TY - THES A1 - Kodes, Jan T1 - Zum Verhältnis von E-Learning-Praktiken Studierender und den E-Learning-Angeboten wie -Potenzialen an Universitäten: eine explorative empirische Studie N2 - In der vorliegenden Dissertation wird untersucht, wie Studierende bei der Prüfungsvorbereitung auf die vorhandenen E-Learning Angebote zurückgreifen wie Dozierende E-Learning Angebote in der Lehre einsetzen und wie die Potenziale von E-Learning-Angeboten an den Universitäten besser ausgeschöpft werden und die Studierenden bei der Prüfungsvorbereitung zu unterstützen. Als Studiendesign wurde eine Kombination von quantitativen und qualitativen Methoden gewählt. An den verschiedenen Fakultäten der Universität Passau wurde zu Beginn eine quantitative Befragung unter Studierenden zu deren Nutzung von Lehrmaterialien und Medienangeboten durchgeführt. Danach folgten qualitative Lehrenden- und Experteninterviews zum Medieneinsatz in der Lehre. Zum Abschluss wurden in einer zweiten quantitativen Befragung Studierender die Zusammenhänge von Lernmotivation, Lernstrategien und Prüfungsangst genauer untersucht. In den Ergebnissen zeigte sich, dass die Studierenden die E-Learning-Angebote nur dann annehmen, wenn sie daraus einen unmittelbaren Nutzen ziehen. Den Lehrenden stehen die entsprechenden Ressourcen zum Einsatz digitaler Medien häufig nicht zur Verfügung. Kurz zusammengefasst bedeutet E-Learning an Universitäten vor allem Folgendes: Hochladen und Verwalten von Lernmaterialien auf Lernplattformen, zusätzlich die Bereitstellung von Videoaufzeichnungen bei Veranstaltungen mit hoher Teilnehmerzahl. Vereinzelt werden noch elektronische Klausuren oder Live Votings angeboten. Des Weiteren konnte nachgewiesen werden, dass die weiblichen Studierenden, unabhängig vom Fachsemester, über eine höhere Lernmotivation als die männlichen Studierenden verfügen. Wenn Studierende sich mehr Lernstrategien zu eigen machen, ist sowohl deren Prüfungsangst als auch die Anzahl der Arbeitsstörungen geringer. Künftig sollten die digitalen Medien verstärkt dazu eingesetzt werden, die Studierenden zur aktiven Mitarbeit anzuregen. Die Lehrenden sollten Zugriff auf spezielle technische Ausrüstungen sowie auf didaktische Qualifizierung und Beratung haben, damit sie auch anspruchsvolle Medienangebote wie Webbasiertes Lernen oder Apps umsetzen können.

First, they are confronted with surging rates of non-communicable diseases (NCDs), and second, climate change will take its toll and is predicted to cause catastrophic health impairments and exacerbate chronic health conditions further. Both will pose a disproportionate health and economic burden on low- and middle-income countries, which are also the countries least able to cope with them. By threatening individual health and socioeconomic improvements, and by putting an immense burden on already constrained health care systems, they impede the progress in poverty reduction and widen health inequities between the rich and the poor. Against this background, this thesis investigates the potential of NCD prevention and treatment measures in the context of Southeast Asia, with case studies in Indonesia. Specifically, it seeks to understand what kind of health interventions have the potential to be (cost-)effective considering the cultural background, lifestyle, health literacy and health system capacities in the region. Further, this thesis analyzes the interplay between NCDs and climate change and assesses the financial burden that both might pose in the decades to come. Hence, this thesis contributes to a better understanding of how the two health challenges of the 21st century, NCDs and climate change, can be addressed in the context of Southeast Asia and offers insights into what type of health policies and interventions can play a supportive role.

Recently, different cutting edge technologies have been addressed in the Financial Technology (FinTech) domain, including numeracy understanding, opinion mining and financial ocument processing. In this thesis, we are interested in analyzing the arguments of financial experts with the goal of supporting investment decisions. Although various business studies confirm the crucial role of argumentation in financial communications, no work has addressed this problem as a computational argumentation task. In other words, the automatic analysis of arguments. In this regard, this thesis presents contributions in the three essential axes of theory, data, and evaluation to fill the gap between argument mining and financial text. First, we propose a method for determining the structure of the arguments stated by company representatives during the public announcement of their quarterly results and future estimations through earnings conference calls. The proposed scheme is derived from argumentation theory at the micro-structure level of discourse. We further conducted the corresponding annotation study and published the first financial dataset annotated with arguments: FinArg. Moreover, we investigate the question of evaluating the quality of arguments in this financial genre of text. To tackle this challenge, we suggest using two levels of quality metrics, considering both the Natural Language Processing (NLP) literature of argument quality assessment and the financial era peculiarities. Hence, we have also enriched the FinArg data with our quality dimensions to produce the FinArgQuality dataset. In terms of evaluation, we validate the principle of ensemble learning on the argument identification and argument unit classification tasks. We show that combining a traditional machine learning model along with a deep learning one, via an integration model (stacking), improves the overall performance, especially in small dataset settings. In addition, despite the fact that argument mining is mainly a domain dependent task, to this date, the number of studies that tackle the generalization of argument mining models is still relatively small. Therefore, using our stacking approach and in comparison to the transfer learning model of DistilBert, we address and analyze three real-world scenarios concerning the model robustness over completely unseen domains and unseen topics. Furthermore, with the aim of the automatic assessment of argument strength, we have investigated and compared different (refined) versions of Bert-based models that incorporate external knowledge in the decision layer. Consequently, our method outperforms the baseline model by 13 ± 2% in terms of F1-score through integrating Bert with encoded categorical features. Beyond our theoretical and methodological proposals, our model of argument quality assessment, annotated corpora, and evaluation approaches are publicly available, and can serve as strong baselines for future work in both FinNLP and computational argumentation domains. Hence, directly exploiting this thesis, we proposed to the community, a new task/challenge related to the analysis of financial arguments: FinArg-1, within the framework of the NTCIR-17 conference. We also used our proposals to react to the Touché challenge at the CLEF 2021 conference. Our contribution was selected among the «Best of Labs».

Increased media literacy in the population is one way to counter these issues and their implications. This especially applies to the sub‐concept of journalism literacy, focusing on the ability to consume news critically and reflectively, thus enabling democratic participation. For media companies, promoting journalism literacy seems logical for economic and altruistic reasons. However, research on German initiatives is scarce. This article presents an explorative qualitative survey of experts from seven media companies offering journalistic media education projects in German schools, focusing on the initiatives’ content, structure, and motivation. Results show that initiatives primarily aim at students and teachers, offering mostly education on journalism (e.g., teaching material) and via journalism (e.g., journalistic co‐production with students). While these projects mainly provide information on the respective medium and journalistic practices, dealing with disinformation is also a central goal. Most initiatives are motivated both extrinsically (e.g., reaching new audiences) and intrinsically (e.g., democratic responsibility). Despite sometimes insufficient resources and reluctant teachers, media companies see many opportunities in their initiatives: Gaining trust and creating resilience against disinformation are just two examples within the larger goal of enabling young people to be informed and opinionated members of a democratic society.

The SCRATCH programming environment is particularly popular, with more than 90 million registered users at the time of this writing. While the block-based nature of S CRATCH helps learners by preventing syntactical mistakes, there nevertheless remains a need to provide feedback and support in order to implement desired functionality. To support individual learning and classroom settings, this feedback and support should ideally be provided in an automated fashion, which requires tests to enable dynamic program analysis. In prior work we introduced W HISKER , a framework that enables automated testing of S CRATCH programs. However, creating these automated tests for S CRATCH programs is challenging. In this paper, we therefore investigate how to automatically generate W HISKER tests. Generating tests for S CRATCH raises important challenges: First, game-like programs are typically randomised, leading to flaky tests. Second, S CRATCH programs usually consist of animations and interactions with long delays, inhibiting the application of classical test generation approaches. Thus, the new application domain raises the question of which test generation technique is best suited to produce high coverage tests capable of detecting faulty behaviour. We investigate these questions using an extension of the W HISKER test framework for automated test generation. Evaluation on common programming exercises, a random sample of 1000 S CRATCH user programs, and the 1000 most popular S CRATCH programs demonstrates that our approach enables W HISKER to reliably accelerate test executions, and even though many SCRATCH programs are small and easy to cover, there are many unique challenges for which advanced search-based test generation using many-objective algorithms is needed in order to achieve high coverage.

Institutional quality has been examined using broad indices of rule of law, the rate of murder, the share of the shadow economy and provision of public goods. Nonetheless, we need to locate the specific institutional conditions under which the curse manifests since some “rule of law” countries like Nigeria and Angola are generally classified as resource cursed. In this review, I argue that managing and distributing natural resource wealth through a centralised planning strategy and lack of a binding long-term national development plan are institutional conditions that encourage government unaccountability as they do not restrict policy makers against discretionary distribution of natural resource windfall, rent seeking, clientelism and corruption which contribute to poor economic development and growth. Also, inadequate regulations on how to address the potential or actual impacts of natural resource extraction on the livelihood of local people and the environment tend to precipitate grievance-induced resource conflict.

Because the internet is a highly volatile medium and online content can become inaccessible after the campaign season, new challenges for research arise as well as the need for the preservation of online content. Moreover, the sheer volume of data researchers have to deal with has reached levels where traditional methods are being highly challenged. This paper puts forth a web harvesting workflow with a strong focus on granular extraction of unstructured information (publication dates) for automated analysis. As our approach is methodological, we would like to point out the benefits that researches in political science may draw from adapting our methodology. We demonstrate this by analysing an event-based web crawl of German parties participating in the election campaign for the European Parliamentary Election in 2019. We employ distant reading methods to generate topic models, which are subsequently evaluated by hermeneutic analysis of a subset of the data.

By reviewing both the evolution of those distinctions over the previous decades and the ways in which they have been used in quantitative empirical research, we argue that the CED's evolution has been a partial success story, whereas discourse around the NPD has not seen substantial development. Despite lingering inconsistencies, researchers drawing on the CED have been successful in addressing different lines of critique and in using the CED as a heuristic for investigating notions of nationhood as expressed in public perceptions. In contrast, there has been only limited dialogue between theoretical and empirical approaches to the NPD. The article illustrates how research drawing on the NPD could profit from the CED's evolution. We close by providing a conceptual roadmap to guide the path towards more terminological clarity and to construct more theoretically robust measures for nationalism and patriotism. We specifically suggest that nationalism and patriotism should be consistently understood as ideal types that citizens can simultaneously hold to varying degrees.

A closure system is algebraic if and only if it is a patch closed subset of the ambient algebraic lattice. Every subset X in an algebraic lattice P generates a closure system〈X〉P . The closure system〈Y 〉P generated by the patch closure Y of X is the patch closure of〈X〉P.

A related problem is to find representations for multiple input graphs that coin- cide on subgraphs shared by the input graphs. A common restriction is the sunflower case where the shared graph is the same for each pair of input graphs. These problems translate to the setting of comparability graphs where the representations correspond to transitive orientations of their edges. We use modular decompositions to improve the runtime for the orientation extension problem and the sunflower orientation problem to linear time. We apply these results to improve the runtime for the partial represen- tation problem and the sunflower case of the simultaneous representation problem for permutation graphs to linear time.

An investigation into relative warning density and external software quality on the example of Apache open source projects JF - Empirical Software Engineering N2 - Automated Static Analysis Tools (ASATs) are part of software development best practices. ASATs are able to warn developers about potential problems in the code. On the one hand, ASATs are based on best practices so there should be a noticeable effect on software quality. On the other hand, ASATs suffer from false positive warnings, which developers have to inspect and then ignore or mark as invalid. In this article, we ask whether ASATs have a measurable impact on external software quality, using the example of PMD for Java. We investigate the relationship between ASAT warnings emitted by PMD on defects per change and per file. Our case study includes data for the history of each file as well as the differences between changed files and the project in which they are contained. We investigate whether files that induce a defect have more static analysis warnings than the rest of the project. Moreover, we investigate the impact of two different sets of ASAT rules. We find that, bug inducing files contain less static analysis warnings than other files of the project at that point in time. However, this can be explained by the overall decreasing warning density. When compared with all other changes, we find a statistically significant difference in one metric for all rules and two metrics for a subset of rules. However, the effect size is negligible in all cases, showing that the actual difference in warning density between bug inducing changes and other changes is small at best.

The material traces of writing were understood to outlive their creators and promise to resurrect the authorial body through the magic of the relic. This article reconstructs how authorial script gradually transformed into a collectible object pursued as a memento and a commodity. Letters, drafts, and fair copies by major modern writers found their way into the collections of British aristocrats and American industrialists at the same time that hunting for literary autographs diversified into a middle-class pursuit. Surveying recent scholarship on nineteenth-century collecting and material culture, the essay offers a condensed cultural history of the literary manuscript as a collectible and draws attention to how collectors and collecting feature in fictional texts of the period. It focuses on the artefactual mobility and custodial afterlives of Romantic papers in Victorian literature and culture, exploring a form of collecting which crossed boundaries between periods and national literary traditions.

The injection attacks can also target embedded applications running on processors like ARM and Xtensa by exploiting memory bugs and maliciously altering the program’s behavior or even taking full control over a system. Especially, ARM’s support of low power consumption without sacrificing performance is leading the industry to shift towards ARM processors, which advances the attention of injection attacks as well. In this thesis, we are considering web applications and embedded applications (running on ARM and Xtensa processors) as the target of injection attacks. To detect injection attacks in web applications, taint analysis is mostly proposed but the precision, scalability, and runtime overhead of the detection depend on the analysis types (e.g., static vs dynamic, sound vs unsound). Moreover, in the existing dynamic taint tracking approach for Java- based applications, even the most performant can impose a slowdown of at least 10–20% and often far more. On the other hand, considering the embedded applications, while some initial research has tried to detect injection attacks (i.e., ROP and JOP) on ARM, they suffer from high performance or storage overhead. Besides, the Xtensa has been neglected though used in most firmware-based embedded WiFi home automation devices. This thesis aims to provide novel approaches to precisely detect injection attacks on both the web and embedded applications. To that end, we evaluate JavaScript static analysis frameworks to evaluate the security of a hybrid app (JS & native) from an industrial partner, provide RIVULET – a tool that precisely detects injection attacks in Java-based real-world applications, and investigate injection attacks detection on ARM and Xtensa platforms using hardware performance counters (HPCs) and machine learning (ML) techniques. To evaluate the security of the hybrid application, we initially compare the precision, scalability, and code coverage of two widely-used static analysis frameworks—WALA and SAFE. The result of our comparison shows that SAFE provides higher precision and better code coverage at the cost of somewhat lower scalability. Based on these results, we analyze the data flows of the hybrid app via taint analysis by extending the SAFE’s taint analysis and detected a potential for injection attacks of the hybrid application. Similarly, to detect injection attacks in Java-based applications, we provide Rivulet which monitors the execution of developer-written functional tests using dynamic taint tracking. Rivulet uses a white-box test generation technique to re-purpose those functional tests to check if any vulnerable flow could be exploited. We compared Rivulet to the state-of-the-art static vulnerability detector Julia on benchmarks and Rivulet outperformed Julia in both false positives and false negatives. We also used Rivulet to detect new vulnerabilities. Moreover, for applications running on ARM and Xtensa platforms, we investigate ROP1 attack detection by combining HPCs and ML techniques. We collect data exploiting real- world vulnerable applications and small benchmarks to train the ML. For ROP attack detection on ARM, we also implement an online monitor which labels a program’s execution as benign or under attack and stops its execution once the latter is detected. Evaluating our ROP attack detection approach on ARM provides a detection accuracy of 92% for the offline training and 75% for the online monitoring. Similarly, our ROP attack detection on the firmware-only Xtensa processor provides an overall average detection accuracy of 79%. Last but not least, this thesis shows how relevant taint analysis is to precisely detect injection attacks on web applications and the power of HPC combined with machine learning in the control flow injection attacks detection on ARM and Xtensa platforms.

This paper seeks to expand the scope of international intelligibility research in this respect by reporting on a large-scale study involving 423 nonnative listeners at different proficiency levels, who transcribed words spoken with another nonnative accent under four conditions that varied in the availability of syntactic, semantic, and schematic cues. The results suggest that co-text and context as well as listening proficiency are crucial variables that ought to receive greater attention in research on international intelligibility. The pedagogical implications of these findings are addressed as well.

Foreign policy change in the US-Cuban dyad JF - Zeitschrift für Friedens- und Konfliktforschung N2 - In foreign policy dyads characterized by enmity, mutual desecuritization can serve as a crucial asset for détente. But how does “the way out of the emergency mode” function, considering mutual securitizations over decades? Embarking from theoretical insights provided by second generation scholars on securitization and desecuritization studies, the authors generate a theory-based model of détente for dyads. This analytical tool contributes to the study of the dissolution of historically grown, mutual (re-)securitization processes in interstate relations. By clarifying the impact and functioning of the four desecuritizing modes (replacement, silencing, change through stabilization, and rearticulation), our model allows us to trace dynamics of change and assess the sustainability of détente. Especially mutual desecuritization as rearticulation has the potential to substantially change the self-other relation with effects on the social structure of a foreign policy dyad. The heuristic case study of US-Cuban relations serves as a prime example of a complex dyad of enmity which became a subject of change due to the Obama–Castro diplomacy in 2014. The study on US-Cuban foreign policy issues before and after 2014 helps to sharpen our understanding of dynamic securitization and desecuritization processes. The overall analysis demonstrates that the modes of desecuritization during the Obama–Castro diplomacy lifted the process of détente to a new and unprecedented level.

The study theoretically refers to the distinction of populism through and by the media, which has been discussed to a great extent in populist political communication research. Empirically, the author focuses on visual representations of politicians on the covers of the German news weekly Der Spiegel as well as those of Compact – a far-right alternative magazine. The article argues that political magazines contribute to how the political is imagined, particularly by the visual messages they convey via their front pages. An image type analysis of both magazines’ covers between 2010 and 2020 is conducted (N = 103) in order to explore patterns in the visual representations of German politicians disseminated by the magazines. On the one hand, the comparison of a mainstream and far-right alternative medium enriches the theoretical debate of how populism is strengthened by opportunity structures through the media. On the other hand, the issue of how populism is actively promoted by the media is addressed.

In dieser Arbeit wird die sprachliche Signifikanz des Zusammenspiels von Frame-Semantik und Plastikwörtern im Kontext der Politik des 21. Jahrhunderts untersucht. Nach der Vorstellung dieser beiden Theorien werden grundlegende Definitionen aus der Frame-Semantik und der Forschung zu Plastikwörtern adaptiert, um das Vokabular in der politischen Kommunikation fachlich adäquat analysieren zu können. Für diese politolinguistische Analyse wurde eigenständig ein Untersuchungskorpus erstellt, das aus Reden und Redeanteilen von deutschen Politikerinnen und Politikern aus dem Zeitraum von 2005 bis 2020 besteht. Das Korpus umfasst Reden bzw. Redeanteile verschiedener Politikerinnen und Politiker. Die korpuslinguistische Analyse soll den Zusammenhang zwischen Frame-Semantik und Plastikwörtern in der Politik, sowie die dabei auftretenden sprachlichen Muster und Praktiken empirisch nachweisen. Hierzu wurde eine com-putergestützte Analyse mithilfe der Programmiersprachen Python und R durchgeführt. Sprache in der Politik bietet einen relevanten Themenbereich der Sprachwissenschaft. Sie ist durch die Medien in der Gesellschaft omnipräsent und betrifft alle Bürgerinnen und Bürger. Aus diesem Grund ist die Bearbeitung dieses Fachgebietes von allgemeinem Interesse.

LoRa is a communication protocol that can cover a wide range with low energy consumption. To evaluate the efficiency of the LoRa Wide-Area Network (LoRaWAN), three criteria can be considered, namely, the Packet Delivery Rate (PDR), Energy Consumption (EC), and coverage area. A set of transmission parameters have to be configured to establish a communication link. These parameters can affect the data rate, noise resistance, receiver sensitivity, and EC. The Adaptive Data Rate (ADR) algorithm is a mechanism to configure the transmission parameters of EDs aiming to improve the PDR. Therefore, we introduce a new algorithm using the Multi-Armed Bandit (MAB) technique, to configure the EDs’ transmission parameters in a centralized manner on the Network Server (NS) side, while improving the EC, too. The performance of the proposed algorithm, the Low-Power Multi-Armed Bandit (LP-MAB), is evaluated through simulation results and is compared with other approaches in different scenarios. The simulation results indicate that the LP-MAB’s EC outperforms other algorithms while maintaining a relatively high PDR in various circumstances.

(SODA 258–267 2007)). We call this new problem online mobile facility location (OMFL). In the OMFL problem, initially, we are given a set of k mobile facilities with their starting locations. One by one, requests are added. After each request arrives, one can make some changes to the facility locations before the subsequent request arrives. Each request is always assigned to the nearest facility. The cost of this assignment is the distance from the request to the facility. The objective is to minimize the total cost, which consists of the relocation cost of facilities and the distance cost of requests to their nearest facilities. We provide a lower bound for the OMFL problem that even holds on uniform metrics. A natural approach to solve the OMFL problem for general metric spaces is to utilize hierarchically well-separated trees (HSTs) and directly solve the OMFL problem on HSTs. In this paper, we provide the first step in this direction by solving a generalized variant of the OMFL problem on uniform metrics that we call G-OMFL. We devise a simple deterministic online algorithm and provide a tight analysis for the algorithm. The second step remains an open question. Inspired by the k-server problem, we introduce a new variant of the OMFL problem that focuses solely on minimizing movement cost. We refer to this variant as M-OMFL. Additionally, we provide a lower bound for M-OMFL that is applicable even on uniform metrics.

Drawn from all classes and originating in societal and political disenfranchisement, in Arendt's understanding they are rebellious nihilists who falsely believe they represent the people as a whole while they exclude any citizens who do not share their tribal nationalism and leader worshiping. Illuminating conditions of their emergence, Arendt also helps to elucidate what drives the populist crowds’ illusions about an uncompromising “sovereign will” they and their leaders claim to embody. Such illusions benefit from broader modern trends eroding differences between facts, opinion, truth, and lies. In public environments suffering from destabilized factual truths, organized lies can easily fill a political vacuum generated by crises of political modernity. Unpacking interrelated theoretical trajectories, it is argued that an Arendtian framework can significantly contribute to the study of present-day authoritarian populism.

Prior research, however, audited Yandex’s algorithms largely within Russia. In contrast, this study is the first to assess the role of Yandex’s web search algorithms as a resource for Russia’s informational influence abroad. To do so, we conduct a comparative algorithm audit of Google and Yandex in Belarus, examining the visibility and narratives of COVID-19-related conspiracy theories in their search results. By manually analysing the content of 1320 search results collected in mid-April to mid-May 2020, we find that, compared with Google, (1) Yandex retrieves significantly more conspiratorial content (2) that close to exclusively suspects US plotters to be behind the pandemic, even though the virus spread from the Chinese city of Wuhan across the globe.

Instead of having colleagues at work, crowd workers connect in online communities. We investigate how crowd workers build professional holding environments in online communities to compensate for the lack of organisational structures and we consider how they craft their crowd work activities to enhance their work experience and reduce its long-term precarity. Following a qualitative research design, this paper uses 675 forum interactions collected across six online communities. Based on our findings, we propose the concept of professional holding environments and provide a model for building such holding environments and job crafting in online communities. We thereby expand previous research on holding environments comprised of family members and friends by revealing the impact of professional online communities and their role in professionalisation and crafting supportive social structures in online crowd work.

It is well known that the performance of EAs may depend drastically on these parameters. Recent theoretical studies have shown that self-adjusting parameter control mechanisms that tune parameters during the algorithm run can provably outperform the best static parameters in EAs on discrete problems. However, the majority of these studies concerned elitist EAs and we do not have a clear answer on whether the same mechanisms can be applied for non-elitist EAs. We study one of the best-known parameter control mechanisms, the one-fifth success rule, to control the offspring population size λ in the non-elitist (1, λ) EA. It is known that the (1, λ) EA has a sharp threshold with respect to the choice of λ where the expected runtime on the benchmark function OneMax changes from polynomial to exponential time. Hence, it is not clear whether parameter control mechanisms are able to find and maintain suitable values of λ. For OneMax we show that the answer crucially depends on the success rates (i. e. a one-(s + 1)-th success rule). We prove that, if the success rate is appropriately small, the self-adjusting (1, λ) EA optimises OneMax in O(n) expected generations and O(n log n) expected evaluations, the best possible runtime for any unary unbiased black-box algorithm. A small success rate is crucial: we also show that if the success rate is too large, the algorithm has an exponential runtime on OneMax and other functions with similar characteristics.

Evidence from two representative studies JF - Political Psychology N2 - This article calls for revisiting the predominant yet flawed nationalism-patriotism dichotomy, which has to date remained unchallenged. It advocates for a more nuanced triad: nationalism, exclusively referring to the nation; patriotism, revolving around the homeland; and democratic patriotism, with democracy as its object of attachment. This novel conceptual approach explicitly theorizes these three objects of attachment, which have hitherto rarely been considered. In so doing, the article synthesizes the field's predominant research traditions that have not been fully recognized as diverging nor been simultaneously investigated. By responding to calls for more theoretically robust measures, it not only makes a theoretical but also an empirical contribution to the field. Drawing on data from a representative sample (N = 1875) in Germany in 2022, the study introduces a three-factor measurement model of nationalism, patriotism, and democratic patriotism. Taking into account both the antecedents of the triad and its impact on outgroup hostility, the measures are further validated. To establish its applicability in non-German contexts, the model is additionally supported using data from a representative sample (N = 1164) in Denmark in 2022.

Due to the complexity of such distributed systems, the optimization of energy allocation is a non-trivial task, especially considering constraints and limitations introduced by distributed devices or sub-systems. Additionally, the variety of devices forces approaches to be highly situational and not universally applicable. In this paper, a two-level optimization scheme is proposed, which aims at reducing the optimization complexity of sector-coupled systems. The multi-vector optimization embedded in the two-level optimization scheme is formulated as a mixed-integer linear problem, optimizing the energy flow between domains, which are modeled as an abstraction of a sector. Distributed devices are modeled as components that represent an abstraction of devices connected to an energy domain. The optimization process is evaluated based on the data from a residential complex in Ghent, Belgium. It shows that the approach is capable of minimizing costs, CO2 emissions, and dependency on external resources.

Here, 𝐻 is the Hilbert transform. This complexification of functions allows for an analysis of their amplitude and phase information and has ever since given well-interpretable insight into the properties of the signals over time. The idea of complexification has been reconsidered with regard to many aspects: examples are the dual tree complex wavelet transform, or via the Riesz transform and the monogenic signal, that is, a multi-dimensional version of the Hilbert transform, which in combination with multi-resolution approaches leads to Riesz wavelets, and others. In this context, we ask two questions: - Which pairs of real orthonormal bases (ONBs), Riesz bases, frames and Parseval frames {𝑓 𝑛 } 𝑛∈ℕ and {𝑔 𝑛 } 𝑛∈ℕ can be “rebricked” to complex-valued ones {𝑓𝑛 + 𝑖𝑔 𝑛 } 𝑛∈ℕ? - And which real operators A allow for rebricking via the ansatz {𝑓𝑛 + 𝑖𝐴𝑓𝑛 } 𝑛∈ℕ? In this short note, we give answers to these questions with regard to a characterization which linear operators A are suitable for rebricking while maintaining the structure of the original real valued family. Surprisingly, the Hilbert transform is not among them.

The ten essays originate from discussions about Social Memory Theory and the New Testament at international conferences, three of them are translations of German contributions, while two are published for the first time in this volume.

Gesellschaftliche Transformation, autonome Materialität und der Fall des Digital Farming JF - Berliner Journal für Soziologie N2 - Nachhaltigkeit und Digitalisierung sind zwei Tendenzen gesellschaftlichen Wandels, die in verschiedene Richtungen weisen. Nachhaltigkeit wird als angestrebte, jedoch im Ergebnis unzureichend bleibende Veränderung gesehen, während Digitalisierung – erwünscht oder auch nicht – schlicht erfolgt. Diese Diskrepanz zu untersuchen, ist eine Herausforderung auch für die soziologische Theorie. Nachdem Nachhaltigkeit und Digitalisierung bislang meist unabhängig voneinander in den Blick genommen wurden, erlaubt eine materialitätstheoretisch erweiterte Gesellschaftstheorie ein soziologisches Zusammendenken und eine Erklärung für die Unterschiedlichkeit der Dynamiken gesellschaftlichen Wandels: In der spezifischen, nämlich autonomen Materialität der modernen Gesellschaft ist Digitalisierung bereits angelegt, während eine nachhaltige Entwicklung eine Transformation dieser Materialität selbst erfordert. Am Fallbeispiel des Digital Farming wird diese These näher ausgeführt. Den Abschluss des Beitrags bilden Überlegungen zu Herausforderungen, Bedingungen und Möglichkeiten einer nachhaltigen Digitalisierung.

To substantiate this statement, the mechanism of litigation finance will be scrutinized first, alongside its application to date in the four jurisdictions where its usage is established. Secondly, features characteristic of environmental disputes will be identified in order to assess the potential of their applicability to litigation finance. Finally, these two domains are analyzed in an integrated manner, through case studies of environmental disputes which have been financed to identify key challenges as well as potential impact. In conclusion, this thesis describes how litigation finance can be effectively employed for environmental disputes and offers a guideline for financing environmental disputes successfully.

Städte müssen auf die zunehmenden Verkehrsbelastungen und Umweltprobleme reagieren, wobei der Fahrradverkehr als eine umweltfreundliche Alternative eine wichtige Rolle einnimmt. In diesem Kontext richtet sich die Aufmerksamkeit dieser Arbeit auf Gunzenhausen, eine Stadt im Fränkischen Seenland, die sich bereits seit Jahren aktiv darum bemüht, ihre Fahrradfreundlichkeit zu verbessern. Die im Rahmen dieser Untersuchung durch geführten Umfrage konzentriert sich auf die unterschiedliche Wahrnehmung der Fahrradfreundlichkeit zwischen Einheimischen und Touristen. Dabei ist von Interesse, ob und in welchem Ausmaß diese beiden Gruppen Unterschiede in ihrer Wahrnehmung der Fahrradfreundlichkeit in Gunzenhausen aufweisen. Die Analyse der Ergebnisse macht differierende Ansichten zwischen Einheimischen und Touristen hinsichtlich der Fahrradfreundlichkeit sichtbar. Diese Unterschiede reflektieren individuelle Perspektiven und Erfahrungen, die relevante Konsequenzen für zukünftige Stadtentwicklung darstellen können. Trotz eher geringer Unterschiede ist es wichtig, diese verschiedenen Sichtweisen zu berücksichtigen, um eine weitere Auseinanderentwicklung zu vermeiden. Die gewonnenen Erkenntnisse betonen die Notwendigkeit, ebendiese Unterschiede genauer zu erforschen, um die Fahrradfreundlichkeit in Gunzenhausen zu verbessern und die Ansichten von Einheimischen und Touristen sogar angleichen zu können. Im Kontext der globalen Entwicklung hin zu nachhaltigen Verkehrsmitteln und umweltfreundlichen Mobilitätslösungen gewinnt die Analyse der Fahrradfreundlichkeit in Städten wie Gunzenhausen immer mehr an Relevanz. Die Ergebnisse und die daraus folgenden Erkenntnisse dieser Untersuchung können als Grundlage für eine an den Bedürfnissen verschiedener Bevölkerungsgruppen ausgerichtete Stadtentwicklung dienen. Sowohl die Zukunft des Radfahrens als Verkehrsmittel als auch die Erhaltung und Erweiterung seiner Attraktivität bleiben in Bezug auf die Anpassung städtischer Infrastrukturen weiterhin von Interesse. Die Berücksichtigung unterschiedlicher Perspektiven, wie die für diese Arbeit ausgewählten, kann dabei helfen, eine umfassendere Mobilitätsstrategie zu entwickeln, die die Stadt Gunzenhausen und ähnliche Gebiete umweltfreundlicher und auch lebenswerter gestaltet.

Automatically generating unit tests for dynamically typed programming languages such as Python, however, is substantially more difficult due to the dynamic nature of these languages as well as the lack of type information. Our P YNGUIN framework provides automated unit test generation for Python. In this paper, we extend our previous work on P YNGUIN to support more aspects of the Python language, and by studying a larger variety of well-established state of the art test-generation algorithms, namely DynaMOSA, MIO, and MOSA. Furthermore, we improved our P YNGUIN tool to generate regression assertions, whose quality we also evaluate. Our experiments confirm that evolutionary algorithms can outperform random test generation also in the context of Python, and similar to the Java world, DynaMOSA yields the highest coverage results. However, our results also demonstrate that there are still fundamental remaining issues, such as inferring type information for code without this information, currently limiting the effectiveness of test generation for Python.

In recent years, this approach was successfully used for test campaigns of deep learning frameworks. There is little knowledge about the application of differential testing beyond deep learning. Within this article, we want to close this gap for classification algorithms. We conduct a case study using Scikit-learn, Weka, Spark MLlib, and Caret in which we identify the potential of differential testing by considering which algorithms are available in multiple frameworks, the feasibility by identifying pairs of algorithms that should exhibit the same behavior, and the effectiveness by executing tests for the identified pairs and analyzing the deviations. While we found a large potential for popular algorithms, the feasibility seems limited because, often, it is not possible to determine configurations that are the same in other frameworks. The execution of the feasible tests revealed that there is a large number of deviations for the scores and classes. Only a lenient approach based on statistical significance of classes does not lead to a huge amount of test failures. The potential of differential testing beyond deep learning seems limited for research into the quality of machine learning libraries. Practitioners may still use the approach if they have deep knowledge about implementations, especially if a coarse oracle that only considers significant differences of classes is sufficient.

We extend the aforementioned result of Roberts and Rosenthal (Stoch Model 18(2):257–280, 2002) by developing a theory which identifies conditions, in terms of a generalized level set function, that imply an explicit lower bound on the spectral gap even in a general slice sampling context. Verifying the identified conditions for polar slice sampling yields a lower bound of 1/2 on the spectral gap for arbitrary dimension if the target density is rotationally invariant, log-concave along rays emanating from the origin and sufficiently smooth. The general theoretical result is potentially applicable beyond the polar slice sampling framework.

Machine learning experiments usually tend to be more ad-hoc in nature, and results are communicated most often in the form of a publication. Experimental details are often omitted due to size or time constraints, or simply because the complexity in terms of technical setup or parametrization became intractable. Even access to code bases, disregard important properties of the environment and experimental setup, like for example random generators or computing infrastructure. At the same time, tracking and communicating an often inherently exploratory scientific process is a task with considerable effort. We explored different venues to tackle these issues from a data science engineering point of view. The efforts resulted in PyPads, a framework providing an infrastructure to extend experimental setups with logging, communication and analysis features in a mostly non-intrusive way. PyPads can be extended to different Python-based frameworks, utilizing community driven, descriptive metadata in an effort to harmonize library specific logs in an ontology. Meanwhile, we also try to emphasize similarities to practices in software engineering, which have turned out to be essential in practical applications.

While these grassroots movements emerged under an authoritarian government that showed little interest in organic agriculture, the turn of the 21st century saw the rapid involvement of the Indonesian government in supporting, regulating and, arguably, commodifying organic agriculture. Institutionalization triggered diverse responses from competing organic actors, reflecting their different standpoints and knowledges. In this context, a transdisciplinary approach is deemed suitable to provide context-specific insights into organic agriculture. This dissertation draws on anthropology and Science and Technology Studies (STS) to explore the politics of knowledge of organic agriculture in Yogyakarta, Indonesia, as a contribution to a critique of transdisciplinarity. My interest on the hierarchization of different knowledges is inspired by the work of anthropologists of knowledge that asks how the communities they study construct knowledge and how they themselves construct knowledge about these communities. Since transdisciplinary knowledge is co-produced by science and society and reflects their embedded power relations, transdisciplinary research needs to be open to different interpretations, and reflexive towards the unequal distribution of resources, accountability, and responsibility. By linking these two lines of thought, I examine the making of knowledges through reflexive transdisciplinary work. I reflect on how “epistemic living space” (Felt 2009) and “co-presence” (Chua 2015) affect research and shape the politics of knowledge of organic agriculture in Yogyakarta, Indonesia. I argue that the hierarchization of different knowledges of organic agriculture was intertwined with my shifting positionalities, as a field researcher in Indonesia and PhD student at Passau University, as I moved between these two different “field sites”. This cumulative dissertation is divided into two parts. In Part I, “Knowledge in the making”, I present my contributions towards transdisciplinary knowledge production and politics of knowledge of organic agriculture. Part II, “Publications”, comprises the three stand-alone papers. The first contribution is my formulation of the notion of knowledge in the making. The second is my exploration of the ways that reflexive transdisciplinary work, and living and intersubjective experience shape knowledge in the making. The third is my demonstration of how an understanding of knowledge in the making sheds lights on the politics of knowledge of organic agriculture. This approach serves to examine the politics involved in synthesizing the conceptualizations of organic agriculture employed by different actors into one overarching narrative, such as sustainable agriculture or alternative agriculture. My final contribution is the notion of transdisciplinary moments, a conceptualization of transdisciplinary research practice that accounts for the politics of knowledge in which both scientific and extra-scientific actors are embedded. As a conclusion, I share the lessons learned from pursuing a PhD as a cumulative dissertation in an unstructured setting within a German–Indonesian research project on Indonesian organic agriculture. Finally, I identify bodies of literature and strands of thinking for future engagement within transdisciplinary research and discuss their potential to contribute to radical change in the institutional and value structures of contemporary academia.

A fuzzy extractor works in two stages: The generation phase and the reproduction phase. In the generation phase, an Error Correction Code (ECC) is used to compute redundant bits for a given PUF response, which are then stored as helper data, and a key is extracted from the response. Then, in the reproduction phase, another (possibly noisy) PUF response can be used in conjunction with this helper data to extract the original key. It is clear that the performance of the fuzzy extractor is strongly dependent on the underlying ECC. Therefore, a comparison of ECCs in the context of fuzzy extractors is essential in order to make them as suitable as possible for a given situation. It is important to note that due to the plethora of various PUFs with different characteristics, it is very unrealistic to propose a single metric by which the suitability of a given ECC can be measured. First, we give a brief introduction to the topic, followed by a detailed description of the background of the ECCs and fuzzy extractors studied. Then, we summarise related work and describe an implementation of the ECCs under consideration. Finally, we carry out the actual comparison of the ECCs and the thesis concludes with a summary of the results and suggestions for future work. N2 - Diese Arbeit befasst sich mit Fuzzy Extractors, Sicherheitsprimitiven, die häufig in Verbindung mit Physical Unclonable Functions (PUFs) verwendet werden. Ein Fuzzy Extractor arbeitet in zwei Phasen: Der Generierungsphase und der Reproduktionsphase. In der Generierungsphase wird ein Fehlerkorrekturverfahren (ECC) verwendet, um redundante Bits für eine gegebene PUF-Antwort zu berechnen, die dann als Hilfsdaten gespeichert werden, und ein Schlüssel wird aus der Antwort extrahiert. In der Reproduktionsphase kann dann eine andere (möglicherweise verrauschte) PUF-Antwort zusammen mit diesen Hilfsdaten verwendet werden, um den ursprünglichen Schlüssel zu extrahieren. Es ist klar, dass die Leistung des Fuzzy Extractors stark von der Leistung des zugrunde liegenden ECC abhängt. Daher ist es unerlässlich, ECCs in Verbindung mit Fuzzy Extractors zu vergleichen, um sie für eine bestimmte Situation so geeignet wie möglich zu machen. Es ist wichtig, darauf hinzuweisen, dass es aufgrund der Vielzahl verschiedener PUFs mit unterschiedlichen Eigenschaften sehr unrealistisch ist, eine einzige Metrik vorzuschlagen, mit der die Eignung eines bestimmten ECCs gemessen werden kann. Wir beginnen mit einer kurzen Einführung in das Thema, gefolgt von einer detaillierten Beschreibung des Hintergrunds der untersuchten ECCs und Fuzzy Extractors. Anschließend fassen wir verwandte Arbeiten zusammen und beschreiben eine Implementierung der untersuchten ECCs. Schließlich führen wir den eigentlichen Vergleich der ECCs durch und schließen die Arbeit mit einer Zusammenfassung der Ergebnisse und Vorschlägen für zukünftige Arbeiten ab.

Statistical analysis was performed to determine the absolute agreement and consistency of ratings in all iterations, and the correlation between the ratings in terms of content and style. The findings revealed high interrater reliability, with ICC scores ranging from 0.94 to 0.99 for different time periods, indicating that GPT-4 is capable of producing consistent ratings.

The development of ChatGPT and the recently released GPT-4 model has shown competence in solving complex and higher-order reasoning tasks without further training or fine-tuning. However, the applicability and strength of these models in classifying legal texts in the context of argument mining are yet to be realized and have not been tested thoroughly. In this study, we investigate the effectiveness of GPT-like models, specifically GPT-3.5 and GPT-4, for argument mining via prompting. We closely study the model's performance considering diverse prompt formulation and example selection in the prompt via semantic search using state-of-the-art embedding models from OpenAI and sentence transformers. We primarily concentrate on the argument component classification task on the legal corpus from the European Court of Human Rights. To address these models' inherent non-deterministic nature and make our result statistically sound, we conducted 5-fold cross-validation on the test set. Our experiments demonstrate, quite surprisingly, that relatively small domain-specific models outperform GPT 3.5 and GPT-4 in the F1-score for premise and conclusion classes, with 1.9% and 12% improvements, respectively. We hypothesize that the performance drop indirectly reflects the complexity of the structure in the dataset, which we verify through prompt and data analysis. Nevertheless, our results demonstrate a noteworthy variation in the performance of GPT models based on prompt formulation. We observe comparable performance between the two embedding models, with a slight improvement in the local model's ability for prompt selection. This suggests that local models are as semantically rich as the embeddings from the OpenAI model. Our results indicate that the structure of prompts significantly impacts the performance of GPT models and should be considered when designing them.

Nowadays, consumers are required to disclose personal data online multiple times a day and in a variety of different contexts, such as creating user profiles, online payment or using location-based services. Despite consumers’ increasing online privacy concerns, firms rely ever more strongly on consumer data that they convert into a competitive advantage through personalized product recommendations and targeted advertising. In an effort to encourage consumer data disclosure, many firms have focused on building trust as a way to counterbalance privacy concerns and mitigate risk perceptions. Correspondingly, marketing literature has continued to examine the interplay of trust and consumer privacy concerns. While the extant research has considerably advanced our understanding of the role of trust in privacy-related decision-making, the majority of studies has mainly focused on single-stage, dyadic disclosure settings and cognitive decision-making processes. Against this background, the overarching goal of this thesis is to shed light on under-researched data disclosure contexts involving trust and to explore additional facets of the underlying decision-making processes. For example, considering pre- and post-disclosure stages when evaluating consumers’ data disclosure decisions allows for a more holistic picture of the decision-making process. Similarly, social media and sharing economy settings challenge the traditional assumption of purely dyadic consumer-firm data disclosure, thus extending traditional conceptualizations of trust. Across three independent essays, this thesis addresses the overarching research question of how the peculiarities of multi-stage and multi-actor settings shape consumers’ trust-based decision-making strategies.

The presented research results show that CG can effectively optimize both small and very large networks. However, the default machine precision of 32 bits can lead to problems. The best results are only achieved in 64-bits computations. The research also emphasizes the importance of the initialization of the NNs’ trainable parameters and shows that an initialization using singular value decomposition (SVD) leads to drastically lower error values. Surprisingly, shallow but wide NNs, both in Transformer and CNN architectures, often perform better than their deeper counterparts. Overall, the research results recommend a re-evaluation of the previous preference for extremely deep NNs and emphasize the potential of CG as an optimization method. N2 - Zusammenfassend untersucht die vorliegende kumulative Dissertation die Anwendung des konjugierten Gradienten (CG) zur Optimierung künstlicher neuronaler Netzwerke (NNs) und vergleicht diese Methode mit verbreiteten Optimierungsverfahren erster Ordnung, insbesondere dem Stochastischem Gradientenabstieg (SGD). Die in den Arbeiten präsentierten Forschungsergebnisse zeigen, dass CG in der Lage ist, sowohl kleinere als auch sehr große Netzwerke effektiv zu optimieren. Allerdings kann die Maschinen- genauigkeit bei 32-Bit-Berechnungen zu Problemen führen, beste Ergebnisse werden erst in 64-Bit-Fließkommazahlen erreicht. Die Forschung betont auch die Bedeutung der Initialisierung der NN-Parameter und zeigt, dass eine Initialisierung mittels Singulärwertzerlegung zu deutlich geringeren Fehlerwerten führt. Überraschenderweise erzielen flachere NNs bessere Ergebnisse als tiefe NNs mit einer vergleichbaren Anzahl an trainierbaren Parametern, unabhängig vom jeweiligen NN, das die künstlichen Daten erzeugt. Es zeigt sich auch, dass flache, breite NNs, sowohl in Transformer-, als auch in CNN-Architekturen oft besser abschneiden als ihre tieferen Gegenstücke. Insgesamt empfehlen die Forschungsergebnisse eine Neubewertung der bisherigen Präferenz für extrem tiefe NNs und betonen das Potential von CG als Optimierungsmethode.

This era was marked by an expansion of “non-state spheres,” or areas of life of which the Communist state increasingly released its control after Joseph Stalin’s death in 1953. Political elites, architects, and designers, as well as ordinary citizens co-constructed and explored the rising spheres through the languages of their respective fields—by producing regulations and laws, designing and erecting new types of buildings, developing new and modernizing already familiar everyday objects as well as devising new ways of integrating these objects into private and public spaces. Alongside these voices, transformations in the cultural sphere in general, and literature in particular, were most vocal. The late Soviet era witnessed the dissolution of the ossified ideology of socialist realism that focused on the glorification of the “new Soviet man” and had held culture in its tight grips since the 1930s. Starting from the 1950s, writers increasingly focused on portraying areas of life that lay beyond one’s public commitments and experimented with new meanings, codes, and forms to give shape to novel spheres of experience of the “late Soviet man” that can be subsumed under the concept of the “private sphere.” The analytical framework of my dissertation is built around the journey to understand the mechanisms and architecture that powered the imagination of models of distancing oneself from the state and the society at large—scenarios of privacy, as we may call them today. I examine Russian prose and drama of the 1950s–1980s as a laboratory for the ideas of privacy, which was increasingly sought in the society disillusioned by the Communist doctrine and thus progressively alienating from active participation in the public sphere. I analyze the meanings that writers incorporated into new and old forms of domesticity—private flats that became progressively widespread throughout the 1950s–1980s, rooms in communal apartments, individual houses—to determine the spectrum of concepts that nurtured the idea of privacy in the late Soviet literary imagination. I also examine representations of reciprocal paradigms of relations between subjects from which the state and society at large were increasingly excluded. In the examples that I analyze, forms of private withdrawals variate from establishing control over liminal spaces or escaping into the world of feelings and emotions and building a connection to a person or space (significant for the characters for private rather than public reasons) to experimenting with language and pursuing one’s idiolect despite the ubiquitous “officialese,” as well as living in temporalities asynchronous with the public time. Beyond revealing the visions of different, non-state existences in the late Soviet era, my text also advocates examining the role of official literature as a platform for subversion and change that was no less important in an authoritarian state than dissident literature. I see officially published texts as a cultural subaltern who defies the state of affairs and slowly but firmly turns the “state sphere” into a public one by pushing its own agenda through publications that test and gain ground for bolder visions of Soviet life that are not predicated on the commitment to the public sphere. With individual mechanisms of power assertion employed by the state or literature in the late Soviet era well-researched, the framework is still missing that would capture the shifts of borders between the private and public spheres under the influence of these actors. In devising such framework, I build upon sociological theories of disattendability and civil inattention that Erving Goffman conceived to describe conventions of individual behavior and social interaction in public. Extending these theories toward the studies of literary politics, I argue that by envisioning scenarios of a private retreat and bringing them into officially published editions, literature normalized privacy as a late Soviet imaginary and, therefore, continuously heightened its own disattendability, thereby expanding the borders of the private sphere. On the side of the state, the border was defined by the triggers of disturbance of civil inattention: privacy was conceded in return for disattendability. Under such conditions, literature became a bizarre “private kitchen” that performed private and public functions simultaneously—similar to the kitchens in newly-built individual apartments that were popular loci of socialization in the late Soviet era. It turned into a place where one can escape—it became one of the “niches of privacy” where it was possible to discuss and negotiate the world, in which the society lived or to which it should strive. At the same time, it assumed the role of a surrogate for the public sphere within the “state” sphere by pushing its own agenda through the publication of literary texts that sought to imagine a person rather than a cog in the Communist machine and thus transformed socialist realism into a literary current “with a human face.” In my research, privacy, literature, and politics are bound together to reveal a vibrant spectacle of the continuous interaction between the state, cultural elites, and the citizens, in which thresholds are erected and crossed incessantly. Fictional private sites were battlefields for the production and contestation of ideologies, and the exposure of these literary wars to the public eye played a fundamental role in shifting the borders between the private and the public spheres in an authoritarian late Soviet Russia. The patterns of relations between the state and culture that I uncover in my dissertation resonate in neo-authoritarian twenty-first-century Russia, making privacy an important lens for our insight into the role of culture in rising authoritarian and failing democratic systems across the globe.

Gleichzeitig bestehen beim Thema Partizipation aber Forschungslücken, insbesondere mit Blick auf digitale Formen der Partizipation. Letztere stehen erst am Beginn ihres Einsatzes, während die digitalen Medien sowohl die Alltagswelt der Menschen als auch die Planungsverfahren immer stärker berühren. Diese Arbeit befasst sich deshalb mit Partizipationsprozessen zur Beteiligung von Bürgerinnen, Bürgern und anderen Akteuren/Interessensgruppen in kommunalen Projekten und damit, wie diese Partizipationsprozesse im Lichte von aktuellen, modernen Möglichkeiten digitaler Partizipation anwendungsorientiert gestaltet und sowohl in städtischen als auch ländlichen Räumen akteurs- und ergebnisorientiert analog und/oder digital umgesetzt werden können. Das methodische Vorgehen basiert auf einem vor allem qualitativ- und interaktiv-sozialwissenschaftlichen Methodenmix und erfolgt in drei Zyklen: (1) einer initialen Datensammlung mit Fokus auf einem kommunalen Partizipationsprojekt, (2) einer Datensammlung 2 mit einem Fokus auf minimalen Kontrast und Ähnlichkeiten weiterhin im Rahmen des Partizipationsprojekts sowie (3) einer Datensammlung 3 mit einem Fokus auf stärkeren Kontrast und Unterschiede hinsichtlich Aktivität, Alter oder Kultur der Akteure bzw. hinsichtlich des (eher) ländlichen bzw. städtischen Kontextes. Die verwendeten Erhebungsinstrumente (vor allem narrative und problemzentrierte Interviews, Befragungen, teilnehmende Beobachtungen, ein Schulprojekt und die Erhebung digitaler Partizipations- und Forschungsdaten) zeigen die Bedeutung der drei Aspekte Milieu, Akteure und Programm in der Planung, Gestaltung und Durchführung von Partizipationsprozessen. Anhand dieser drei Gesichtspunkte ergibt sich zudem die Antwort auf die zentrale Forschungsfrage dieser Arbeit, wie Partizipationsprozesse in kommunalen Projekten gestaltet werden können, um digitale Formate sowie lokal-regionale Kontexte zu berücksichtigen, und welche Aspekte dabei relevant sind: (1) das analoge Milieu der konkreten (eher) ländlichen bzw. städtischen Kommune sowie das in diesem sozialen und emotionalen Betroffenheits-Raum vorhandene oder von den Verantwortlichen anreichernd eingesetzte digitale Partizipations-Milieu bilden insgesamt den Raum und beeinflussen die Atmosphäre des Raums, innerhalb dem sich der Partizipationsprozess und die einzelnen -formate je nach Projektphase an ggf. unterschiedlichen Veranstaltungsorten als mikrogeographische Milieus in unterschiedlicher Art und Weise realisieren; (2) die sich in verschiedener Weise in den Partizipationsprozess einbringenden Akteure/Interessensgruppen und deren (je nach Ausmaß der tatsächlichen oder emotionalen Betroffenheit ausgeprägte) individuelle Motivation, beeinflussen die Erfordernisse an eine analoge und/oder digitale informative, dialogische und/oder diskursive Kommunikation sowie an eine auf Bildung, Begegnung, Kooperation und Verantwortung bauende analoge und/oder digitale Interaktion im konkreten Partizipationsprozess; (3) mit dem konkreten Programm des Partizipationsprozesses und den einzelnen analogen und/oder digitalen -formaten gestaltet sich ein (Partizipations-)Projekt in unterschiedlicher Ausprägung milieuorientiert (mit der Definition und Analyse des Partizipations-Raums als Kern der Milieuorientierung und der Standortsuche als zusätzlicher Aspekt bei standortbezogenen Projekten), akteursorientiert (auf den Umfang und den Grad der Einflussnahme-Möglichkeit der Akteure/Interessensgruppen von Nicht-Partizipation über Information und Mitsprache bis hin zu Zusammenarbeit und Mitbestimmung sowie Selbstbestimmung der Akteure blickend) sowie ergebnisorientiert (wirtschaftlich hinsichtlich Planung, Umsetzung, Entscheidung, Nachhaltung und Nachhaltigkeit). Die Bedeutung dieser Arbeit besteht zum einen darin, dass sie das theoretische und praktische Verständnis von Partizipationsprozessen erweitert, indem sie die Fokussierung auf gesellschaftliche Interaktionen in städtisch- und ländlich-digitalen Kontexten einführt, den es so bisher nicht gab, und damit auch die Action-Setting-Theorie von Peter Weichhart um digitale und regionale Anwendungsfelder erweitert. Die anwendungsorientierten Handlungsempfehlungen tragen zudem zur milieu-, akteurs- und programmsensiblen Umsetzung moderner Möglichkeiten analoger und/oder digitaler Partizipation bei. Schließlich eröffnet diese Arbeit Anknüpfungspunkte für künftige Forschungen – etwa in der Motivationspsychologie, der Kommunikations- und Politikwissenschaft, der Volkswirtschafts- oder der Betriebswirtschaftslehre sowie mit Blick auf andere räumliche Maßstäbe bis hin zu landes-, bundes- und europa-politischen (Partizipations-)Projekten. N2 - Great importance and great potential are ascribed to social inclusion and participation, for example by the European Commission and national authorities in funding programs, by the United Nations, in the Sustainable Development Goals of the 2030 Agenda, or by the German Federal Ministry of Education and Research in the High-Tech Strategy 2025. At the same time, however, there are research gaps on the subject of participation, particularly with regard to digital forms of participation. The latter are only just beginning to be used, while digital media are increasingly affecting both people's everyday lives and planning processes. This work therefore deals with processes for the participation of citizens and other actors/interest groups in municipal projects and how these participation processes can be designed in the light of current, modern possibilities of digital participation analogously and/or digitally and in an application-, actor- and result-oriented manner in both urban and rural areas. The methodological approach is based on a primarily qualitative and interactive social science method mix and takes place in three cycles: (1) an initial data collection with a focus on a municipal participation project, (2) a data collection 2 with a focus on minimal contrast and similarities, which continues in the participation project and (3) a data collection 3 with a focus on stronger contrast and differences in terms of activity, age or culture of the actors or in terms of the (rather) rural or urban context. The survey instruments used (mainly narrative and problem-centered interviews, surveys, participatory observations, a school project and the collection of digital participation- and research data) show the importance of the three aspects milieu, actors and program in the planning, design and implementation of participation processes. These three points of view also provide the answer to the central research question of this work, how participation processes in municipal projects can be designed to take digital formats and local-regional contexts into account, and which aspects are relevant: (1) the analogue milieu of the concrete (rather) rural or urban municipality as well as the digital participation milieu, that is present in this social and emotional area of concern or that is used to enrich it by those responsible, form the area as a whole and influence the atmosphere of the area, within which the participation process and the individual formats are realized in different ways at possibly different venues as microgeographical milieus depending on the project phase; (2) the actors/interest groups involved in the participation process in various ways and their individual motivation (depending on the extent of the actual or emotional impact) influence the requirements for analogue and/or digital informative, dialogical and/or discursive communication as well to an analogue and/or digital interaction based on education, encounter, cooperation and responsibility in the concrete process of participation; (3) with the specific program of the participation process and the individual analogue and/or digital formats, a (participation) project is formed milieu-oriented (with the definition and analysis of the participation space as the core of the milieu orientation and the search for a location as an additional aspect in site-related projects), actor-oriented (looking at the scope and degree of the actors/interest groups' ability to exert influence, from non-participation to information and participation to cooperation and co-determination as well as self-determination of the actors) and result-oriented (economically in terms of planning, implementation , decision, follow-up and sustainability) in various forms. The importance of this work is, on the one hand, that it expands the theoretical and practical understanding of participatory processes by introducing a focus on social interactions in urban- and rural-digital contexts that did not exist before. This also expands the Action-Setting-Theory by Peter Weichhart by including digital and regional fields of application. The application-oriented recommendations for action also contribute to the milieu-, actor- and program-sensitive implementation of modern opportunities for analogue and/or digital participation. Finally, this work opens up starting points for future research – for example in motivational psychology, communication and political science, economics or business administration, as well as with a view to other spatial scales, including state, federal and European political (participation) projects.

To gain a competitive edge, companies invest heavily in algorithmic systems (Kappelman et al., 2021), which are considered as one of the most important drivers of today’s economy (Brynjolfsson and McAfee, 2011; Hogharth and Makridakis, 1981; Önkal et al., 2019). Particularly in management accounting, an algorithmic data analysis offers the potential to support a high decision quality, making their usage a key factor for success. However, algorithms can not only support, but also manipulate human decision-making (Roose et al., 2023). Algorithmic advice can lead to overtrust, i.e. to the heuristic replacement of vigilant information seeking and processing in favor of the advice provided (Mosier et al., 2001). The implementation of algorithmic decision support systems is thus no panacea to improve human decision-making. In contrast, they can entail new risks, such as the uncritical use of these algorithms (Boden, 2016). Yet, this ‘dark side’ of algorithms is not sufficiently investigated in the field of management accounting. With advances in machine learning, algorithmic support can become even more of a black box, blurring the reference points for evaluating its advice quality and thus increasing the risk of overtrust. Stephen Hawking even warns that AI will be “either the best, or the worst thing, ever to happen to humanity” (Alex Hern in: The Guardian: Stephen Hawking: AI will be 'either best or worst thing' for humanity, 19th October 2016). Interacting with such algorithmic systems therefore requires data literacy skills for an appropriate use. They seem to be a crucial prerequisite in today’s data-driven world to reap of the benefits of algorithmic systems. If no reflective and critical interaction between human and algorithm can be ensured, the trend towards a digitalized world will be a race against the algorithm (Brynjolfsson and McAfee, 2011). This dissertation takes this understudied critical perspective on the increasing implementation of algorithmic systems and sheds light on different aspects of human-algorithm interaction, ranging from the ability to use data visualization tools to trust calibrations and critical evaluations of algorithmic advices. Study I investigates an adequate information representation of subjective multiple criteria decision problems, an important task in management accounting, to support human decision-making. Study II distinguishes different designs of the human-algorithm interaction investigated in the trust in automation literature and compiles factors influencing the calibration of trust and behavior toward the true capabilities of the algorithm. Study III examines the role of performance feedback on trust and advice usage in a forecasting task for a better understanding of the recently observed phenomenon ‘algorithm aversion’. Finally, Study IV focusses on the risk of overtrust in advice in repeated interactions with a forecasting advisor and investigates the calibration of advice usage. Each study thereby represents an independent contribution and contains all information relevant to the respective research questions asked in the study.

To master these challenges, suppliers need excellent commercial capabilities. This thesis considers these challenges and opportunities in sales, contracting, and pricing of complex B2B solutions in three essays: Essay 1 addresses the increased complexity for solution salespeople, who represent an essential strategic asset in solution selling. In-depth interviews with solution sales managers in study 1 and survey data from matched sales manager-salesperson dyads in study 2, reveal nine specific equifinal configurations of key personal and procedural competencies that qualify individual salespeople in their role and thus determine their solution sales success. The focus of essay 2 lies on B2B export relationships for complex product-service combinations in an international context. A regression analysis based on a survey study with 198 responses shows several direct and indirect effects of contractual and cultural constructs. The results give insights under which cultural framework conditions contract specificity serves as a safeguarding mechanism against uncertainty and opportunism. Essay 3 examines how the bidirectional agency relationship between suppliers and customers and the performance uncertainty of a solution influence B2B customers’ acceptance of performance-based pricing (PBP). Drawing on a cross-industry survey with 196 managers of B2B firms, this study contributes to extend PBP literature by showing how bidirectional agency relationships shape customers’ acceptance of PBP. In sum, this thesis contributes to a better understanding on how to optimize commercial capabilities in the context of national and international solution selling. It thereby focuses on addressing recently identified causes that hinder B2B firms from increasing their margins through solution selling by (1) optimizing the sales force through a better understanding of important resources and capabilities for solution selling, (2) optimizing their contractual set-up through a better understanding of cultural factors and the interplay with contract specificity, and 3) optimizing price policy through a better understanding of framework conditions, which have an impact on customers’ acceptance of PBP.

As a result of climate change and other, direct forms of anthropogenic interference, the magnitude and frequency of such floodings is predicted to continuously increase in the near future. Therefore, it is important to understand the vulnerability of affected people to implement appropriate measures. This research presents a case study on coastal flooding and its impact on livelihoods in the Volta Region of Ghana. The paper utilizes a vulnerability framework that focuses on exposure, susceptibility, as well as the capacities to anticipate, cope with, and recover from the effects of natural hazards. Based on a qualitative approach, the study focusses on those households who were directly affected of a severe tidal flood in November 2021, leading to a total destruction of their property. The research was conducted in March, July and August 2022. It revealed that the studied group had low capacity to anticipate and had no contingency plans in case of relocation. Further, we discovered different strategies that people applied to deal with the situation eight months after the flood event. Most households applied (short term) coping strategies to reestablish their former marine-based livelihood systems. Adaption in terms of long-term adjustment of their livelihoods played only a minor role and could be found in form of out-migration in a limited number of households.

This research addresses how the distributed generation location and capacity impact the operation of the circuit breaker in terms of the response time of the circuit breakers. The relative electrical distances of the faults and distributed generation to the circuit breakers are considered. The impact of distributed generation capacity considering the fault location is characterized using a new index called the heterogeneity index. The electrical distance between distributed generations and circuit breakers and the electrical distance between fault and circuit breaker is considered by a second new index called the electrical distance ratio. Data analysis on simulation results shows that these indices capture the phenomena of protection blinding caused by distributed generation. Results show that a higher distributed generation penetration and faults that are electri cally further away from a circuit breaker show severe cases of protection blinding captured by the indices. Furthermore, it is demonstrated how these indices can identify the worst impacted locations in the distribution grid. A key result is that protection blinding does not necessarily occur solely due to the presence of distributed generation between a circuit breaker and a fault, but is dependent on factors such as distributed generation location in the distribution grid, fault level, fault level distribution across the generation units and fault location.

Exhibition Audiences in Indonesia and Processes of Selection, Reception, and Appropriation Using the Example of the Exhibition "Raden Saleh and the Beginning of Modern Indonesian Painting" N2 - In der Dissertation «Ausstellungen und ihr Erfolg: (Kunst-)Geschichten befragen» wird ein Teilbereich der Bildungsforschung untersucht, nämlich die informelle Bildung im internationalen Kontext. Die Arbeit kombiniert eine ausführliche Analyse einer Ausstellung und deren Publikum und fokussiert sich dabei auf die Perspektive der Besucher*innen. Als Fallbeispiel dient die empirische Forschung zur kunsthistorischen Ausstellung «Raden Saleh und der Beginn der modernen indonesischen Malerei», die 2012 in der Nationalgalerie von Jakarta stattfand. Organisiert als kulturpolitisches Instrument vom Goethe-Institut Indonesien, stellte die Ausstellung eine bedeutende historische Persönlichkeit Indonesiens, Raden Saleh, in den Mittelpunkt. Besonders bemerkenswert war, dass seine Werke erstmals retrospektiv mit Originalgemälden in seiner Heimat gezeigt wurden. Die Ausstellung führte neue Narrative, neu Ausstellungs- und Vermittlungskonzepte ein und weckte großes Interesse beim Publikum, was zu einem außerordentlichen Erfolg führte. Basierend auf Konzepten der kritischen Museologie, (Kunst-)Soziologie und qualitativen Medienforschung untersucht die Arbeit die Ursachen und kurz- sowie langfristigen Effekte des Ausstellungserfolgs. Durch die Erforschung der bisher wenig beachteten Sphäre der Kunstdistribution und informellen Bildung in Indonesien leistet die Arbeit einen wichtigen Beitrag zur Grundlagenforschung der Südostasienwissenschaften. Gleichzeitig adressiert sie verschiedene Desiderate in der Publikumsforschung und liefert Erkenntnisse für eine kritische Ausstellungspraxis auf internationaler Bühne. Unter der Berücksichtigung von vielfältigen Kontexten der Ausstellungsbesucher (Sozio-kulturell, physisch, persönlich) arbeitet die qualitative sowie quantitative Analyse die massgeblichen Erfolgsfaktoren der Ausstellung heraus. Die Besucherforschung zeigte, dass vor allem die urbane Mittelklasse die Ausstellung aufsuchte. Besucher_innen kamen in die Ausstellung mit Vorwissen zu Raden Saleh in Form von Legenden. Dieses Vorwissen verhandelten sie in der Ausstellung neu und passten es an ihre persönlichen Bedürfnisse an. Gleichzeitig generierte sich das Interesse aus bis dato fehlenden Ganzkörpererfahrungen mit historischen Zeitzeugnissen zu Raden Saleh. Der Ausstellungserfolg war nicht nur auf den richtigen Ort, sondern auf den gut gewählten Zeitpunkt zurückführen. Die stattfindenden Feierlichkeiten zu Raden Salehs Geburtstag im Rahmen einer Erinnerungspolitik und diverse stattfindende Diskurse der Kunstwelt fanden in der Ausstellung die richtige Plattform, um Narrative zu Kunst und Geschichte zu verhandeln. Die Analyse der Selektions- und Rezeptionspraktiken der Besuchwer_innen machten die wichtigsten Erfolgsfaktoren der Ausstellung deutlich: ihre Fähigkeit an die oben genannten Kontexte der Besucher_innen anzuknüpfen oder diese für sich zu nutzen. Die Arbeit schließt mit Ergebnissen aus der Aneignungs- und Wirkungsforschung und deren Bewertung ab. Diese zeigen deutlich, dass die Wahrnehmung von Raden Saleh heute maßgeblich durch die Ausstellung «Raden Saleh und der Beginn der modernen indonesischen Malerei» beeinflusst wurde und verdeutlicht damit die Bedeutung und Verantwortung der informellen Lernorte wie Ausstellungen – insbesondere in postkolonialen Kontexten. N2 - In the dissertation "Exhibitions and Their Success: Examining (Art) Narratives", a specific area of educational research is investigated, namely informal education in an international context. The study combines a comprehensive analysis of an exhibition and its audience, focusing on the perspective of the visitors. The empirical research centers on the art-historical exhibition "Raden Saleh and the Beginning of Modern Indonesian Painting," which took place in 2012 at the National Gallery of Jakarta. Organized as a cultural-political instrument by the Goethe-Institut Indonesia, the exhibition highlighted Raden Saleh, a significant historical figure in Indonesia. Notably, this was the first retrospective showcasing his original paintings in his homeland. The exhibition introduced new narratives, as well as innovative exhibition and educational concepts, which garnered substantial public interest, leading to its extraordinary success. Based on concepts from critical museology, (art) sociology, and qualitative media research, the dissertation examines the causes and both the short- and long-term effects of the exhibition's success. By exploring the hitherto under-researched sphere of art distribution and informal education in Indonesia, this work makes a significant contribution to foundational research in Southeast Asian studies. Simultaneously, it addresses various desiderata in audience research and provides insights for a critical exhibition practice on the international stage. Considering the diverse contexts of exhibition visitors (e.g. socio-cultural, physical, personal), the qualitative and quantitative analyses identify the key success factors of the exhibition. Visitor research indicated that the urban middle class predominantly attended the exhibition. Visitors approached the exhibition with pre-existing knowledge of Raden Saleh in the form of legends, which they reinterpreted and adapted to their personal needs. At the same time, their interest was generated by the previously unavailable holistic experiences with historical artifacts related to Raden Saleh. The success of the exhibition was attributed not only to the appropriate location but also to the well-chosen timing. The concurrent celebrations of Raden Saleh's birthday within the framework of commemorative politics and various ongoing art world discourses provided a suitable platform for negotiating narratives of art and history. The analysis of the selection and reception practices of the visitors highlighted the most critical success factors of the exhibition; for example, its ability to connect with or utilize the aforementioned contexts of the visitors. The dissertation concludes with findings from appropriation and impact research and their evaluation. These clearly demonstrate that the perception of Raden Saleh today has been significantly influenced by the exhibition "Raden Saleh and the Beginning of Modern Indonesian Painting", highlighting the importance and responsibility of informal learning sites like exhibitions – especially in postcolonial contexts.

In particular, the ability to drive automatically or even fully autonomously, update control software, and remain connected to the environment allows attackers to infiltrate highly critical vehicle systems and take control without adequate protection. Once not only individual vehicles but entire fleets are dominated by software, cyberattacks could disrupt a significant portion of the infrastructure and expose passengers to substantial risks. This work follows a holistic approach to protecting highly automated software-defined vehicles from cyberattacks by designing and implementing security concepts in the main phases of a vehicle's lifecycle. We use SAE level 4 prototype vehicles to evaluate our proposed techniques. We start with a systematic security requirement analysis using the ISA-62443 standard series, demonstrating how threats can be identified in a collaborative, hierarchical process and how the resulting security risks impact the software and hardware architecture of a self-driving vehicle. We show how this analysis process results in concrete requirements whose consideration reduces the overall security risk to a tolerable level. Subsequently, we develop technical solutions for selected requirements. We begin by securing the CAN and FlexRay legacy protocols, which we foresee being used in specific areas of SDV in a transitional period despite technological changes. To enable vehicle-wide security management, we address the management and distribution of cryptographic keys within such networks, mainly focusing on resource-constrained devices. We propose using lightweight implicit certificates for deriving cryptographic group keys that can be used in CAN networks. Additionally, we demonstrate how the slot-based frame structure of the FlexRay protocol allows for efficient "multi-slot" authentication, for which we calculate cryptographic keys using hash-based key chains. SDV use Ethernet-based communication protocols and custom middleware stacks to transmit large amounts of data in real-time. We develop a three-stage security process for the novel ASOA, which enables the development and central orchestration of system-agnostic functional software components on embedded systems and HPC platforms. After the central specification of the security architecture at the data flow level, security tokens are automatically calculated and distributed for runtime protection of the service-oriented, DDS-based data transmission. Our process ensures the strict separation of function and system knowledge, allowing for cost-effective and adaptable security architecture management. The evaluation in four self-driving, software-defined vehicles demonstrates an average runtime overhead of approximately 5.71%. As the initial risk analysis and actual cyberattacks have shown, protective measures against the compromise of control units must be taken alongside communication security. To address this, we develop a method for verifying and validating the software integrity of control units. A governmental third party confirms a measurement through a digital certificate, proving the examined vehicle's trustworthiness and suitability for participation in automated traffic. In the final step of this work, we present an assessment scheme that allows software-defined vehicles to evaluate security incidents during operation in terms of their maximum expected damage and initiate appropriate countermeasures. We follow the ISO/SAE 21434 standard and model attack paths using a graph representing dependencies among internal vehicle assets to account for the propagation effects of cyberattacks. The assessment of a security incident considers not only the probability of individual attack paths but also the vehicle context. Our practical evaluation demonstrates that we can detect, report, and assess security incidents below the human reaction time in the earlier mentioned prototype vehicles.

Organizations interact with internal and external stakeholder groups which not necessarily have the same legitimacy expectations. Due to several reasons, such as the adoption of new laws or the invention of new technologies, stakeholders’ expectations of legitimate actions can change in the course of time. Thus, to respond to changing stakeholder’s expectations, as integral part of a changing environment, is complex. The main objective of this dissertation is to answer the research question: “How do organizations respond to changing stakeholder’s expectations in context of sustainable development?”. Building on two empirical settings with four essays, this dissertation provides insights into organizations’ responses as reaction to changing stakeholder expectations with regard to sustainable development. In particular, it takes a closer look on the interplay between internal stakeholders, such as employees, and external stakeholders, such as politics or customers. The first essay summarizes the organizational factors for the implementation of a research data management (RDM) system within higher education institutes (HEI) and how they interact with each other. Based on Leavitt’s (1965) classical model of organizational change, the essay provides an overview about the interrelation between the individual components that make up an RDM system. The second essay investigates how early career researchers within HEI make use of different respond strategies to the state, market, professional, and community logic in context of RDM. It provides insights how employees deal with changing environmental conditions and the organization’s response to them. The third essay analyses the shift from voluntary to mandatory sustainability reporting and demonstrates different strategies organizations adopt to respond to it. The fourth essay incorporates the findings of the third essay and investigates which factors influence the organization’s strategy to respond. It focuses on the interface between the top management team and the chief executive officer. This dissertation makes at least two overall contributions to management and organization studies research. First, it emphasizes the role of different stakeholder groups and their impact on the organizations’ activities. Second, this dissertation shows the value of connecting different theoretical approaches such as institutional logics, upper echelon theory, and organizational transparency research in context of organizational legitimacy and demonstrates that a nuanced view is necessary to understand the concept of organizational legitimacy. This cumulative dissertation is structured as follows. Part A is an introduction to the study organizational legitimacy. Part B contains the four essays.

Die katholischen Synoden im frühneuzeitlichen Polen-Litauen bildeten hiervon keine Ausnahme: Obwohl Versammlungen des Klerus, waren sie stark ins politische System eingebunden, das sich zu einer Wahlmonarchie mit starkem Adel und parlamentarischen Elementen entwickelte. Diese Arbeit untersucht systematisch die politischen Aspekte der Provinzial- und Primatialsynoden in Polen-Litauen von 1447 bis 1643 aus der Perspektive der Kulturgeschichte des Politischen. Zunächst wurde eine bereinigte Liste aller Synoden erstellt, um Frequenz und Verteilung zu analysieren und diese mit der Aktivität des Reichstags zu vergleichen. Die Arbeit untersucht in der Folge die institutionelle Ausformung der Synoden, ihre Vor- und Nachbereitung sowie die Abläufe und Beratungen. Zudem beleuchtet sie die Funktionen, die diese Klerus-Versammlungen im politischen System erfüllten, und den Beziehungen, die sie zu anderen politischen Akteuren ‒ insbesondere dem König, dem Adel und dem Reichstag ‒ unterhielten. Da sich im Untersuchungszeitraum von zweihundert Jahren erhebliche Veränderungen in Häufigkeit, Funktionen und politischen Beziehungen zeigten, wurde dieser in vier Abschnitte zu je rund fünfzig Jahren gegliedert: Die erste Phase deckt sich weitestgehend mit der Regentschaft Kazimierzs IV (1447-1492), in der sich die parlamentarischen Elemente im politischen System Polen-Litauens herausbildeten. In der zweiten Phase (1493-1561) traf das nun voll entwickelte System auf eine rege Synodaltätigkeit. Der dritte Abschnitt beleuchtet die Phase nach dem abrupten Einbruch der Synodaltätigkeit (1561-1600). Der vierte Abschnitt (1600-1643) untersucht das moderate Wiederaufleben der Synoden in jener Epoche, in der sich das politische System durch ein Erstarken des Klientelwesens veränderte. Innerhalb jedes Abschnitts werden die vier Hauptfragen nach Frequenz, institutioneller Ausformung, Funktionen und Beziehungen zu politischen Akteuren behandelt. N2 - In the Early Modern period, church and secular politics were closely intertwined. The Catholic synods in early modern Poland-Lithuania were no exception: although they were assemblies of the clergy, they were deeply embedded in the political system, which evolved into an elective monarchy with a powerful nobility and parliamentary elements. This study systematically examines the political aspects of the provincial and primatial synods in Poland-Lithuania from 1447 to 1643 from the perspective of the cultural history of politics. First, a cleaned list of all synods was compiled to analyze their frequency and distribution and to compare them with the activity of the Sejm (parliament). The study then examines the institutional structure of the synods, their preparation and follow-up, as well as the proceedings and deliberations. It also highlights the functions these clerical assemblies fulfilled within the political system and their relationships with other political actors—particularly the king, the nobility, and the Sejm. Given the significant changes in frequency, functions, and political relationships over the two-hundred-year period, the study is divided into four sections of approximately fifty years each: The first phase largely coincides with the reign of Kazimierz IV (1447-1492), during which the parliamentary elements of the political system in Poland-Lithuania emerged. In the second phase (1493-1561), this now fully developed system coincided with active synodal activity. The third section examines the phase following the abrupt decline in synodal activity (1561-1600). The fourth section (1600-1643) explores the moderate revival of the synods during the period when the political system was transformed by a strong increase of clientelism. Within each section, the four main questions regarding the frequency, institutional structure, functions, and relationships of the synods with political actors are addressed.

The persistent male dominance in this domain has created an urgent need for more heterogeneous groups in software engineering. This lack of diversity not only hinders underrepresented groups from entering the field but also prevents them from gaining initial programming experiences, which are a core component of software engineering and essential for developing computational thinking. To address this crisis and its implications, early interventions are key in shaping positive perceptions, building confidence, and sparking initial interest in programming among underrepresented groups before societal stereotypes of programming as a nerdy field manifests. This means starting with basic programming courses for children and continuing through to first-year university students in order to foster technical skills and computational thinking, alongside creativity and collaboration. However, there is limited understanding of how introductory programming course designs impact diversity-dependent characteristics to create welcoming and learning-friendly environments. This understanding is particularly important for underrepresented groups, especially girls, to benefit from their first programming experiences as they are often hindered by the initial perception of programming as (1) abstract and unappealing, and (2) non-social to novices. Engaging, creative, and relatable topics in programming courses might demystify complex programming concepts, making them more accessible, less intimidating, and appealing. However, understanding programming is not just about the content---it is also about the context in which it is learned. Introducing programming as social activity is important, particularly for young learners. By emphasizing team work, we might encourage collaboration and peer support, counteracting the lone-wolf programmer stereotype. Therefore, this doctoral thesis investigates the effects of both key aspects in programming courses---(1) topic choices and (2) group constellations---on young programming novices. The aim is to provide a holistic understanding of how different course designs can support diverse learners and promote gender equality in programming education. While this research primarily addresses gender diversity due to the persistent gender gap in software engineering, it also examines additional diversity dimensions, including age, ethnicity, prior programming experience, disabilities, and educational background. A total of 13 studies were conducted within this thesis, examining the current state of educational settings and utilizing various introductory programming courses designed for children aged 8 to 18, as well as first-year university students. These studies employed different programming environments, such as Scratch and Sonic Pi, and incorporated a variety of topics and group constellations to observe their effects on student outcomes. By using a mixed-methods design, data were gathered through surveys, observations, and both data-driven and manual code analysis. Key findings reveal that it is particularly noteworthy how children utilize the programming environment to engage with and creatively express topics aligned with their interests which also align mostly with gender-stereotypes, including elements from internet and popular culture as well as socio-cultural narratives. However, gender-sensitive and neutral topic choices enhance engagement, self-efficacy, contribution, code quality and creative output, while also contributing to reduce stereotypical beliefs about programming, particularly among girls. In line with the findings for the course topic, group constellations also influence programming experiences. In particular, introducing pair programming in courses shows a promising approach for young learners, but attention must be paid to mitigate socially learned gender-stereotypical behaviours. Another finding indicates that, unlike professional software teams, mixed-diverse student teams often encounter substantial challenges, thus benefit from clear communication guidelines and supportive environments to promote better collaboration. This doctoral thesis concludes with guidelines for designing more effective and inclusive introductory programming courses. These recommendations include using gender-sensitive course materials, allowing for creative freedom through topic choices while encouraging the use of advanced programming concepts, promoting collaboration through pair programming while fostering enhanced communication, boosting self-efficacy with quick positive feedback for girls in particular, and providing emotional support for underrepresented groups. By following these guidelines, educators can create more engaging, inclusive, and effective programming courses. This may ultimately promote a more equitable and diverse future generation of professional software developers while also fostering computational thinking, encouraging a broader interest in programming among all young learners.

In addition, the teachers of the participating pilot project schools will also be quantitatively surveyed at two points in time, one year apart, about their subjective assessments regarding the implementation of inclusive gifted education. Within the scope of this work, numerous favourable and some inhibiting factors in the implementation of inclusive gifted education are examined, which schools can include and take into account in their development processes in the context of inclusive gifted education. In this way, inclusive gifted education can benefit all pupils.

Letzterer widmet sich der theoretischen Erfassung von Möglichkeitsräumen in der Außenpolitik. In theoriegeleiteten Fallstudien analysiert die Arbeit den Zusammenhang zwischen Identitäten, Diskursen und Verhaltensweisen mit dem Ziel, außenpolitische Möglichkeitsräume in unterschiedlichen Handlungskontexten zu ermitteln. Das im Mantelteil neu generierte Modell zur Erforschung dieser Möglichkeitsräume überspannt die verschiedenen Theorien der Einzelbeiträge und zeigt so den Mehrwert einer konstitutiven sozialkonstruktivistischen Außenpolitiktheorie auf. Im Modell werden die folgenden drei Analysefelder herausgearbeitet: 1) Historische Vorstudie, 2) Fallspezifische Diskursanalyse und 3) Konstitutive Wirkungen. Anhand der Fallstudien wird dargelegt, wie der außenpolitische Rechtfertigungsdiskurs die Identität und damit den Möglichkeitsraum des Akteurs entweder reproduziert, erweitert oder durchbricht und welche konkreten Implikationen dies für den aktuellen und zukünftigen Handlungsspielraum in der Außenpolitik hat. Im Ergebnis können unter Anwendung des Modells die langfristigen Wirkungen von politischen Reaktionen auf Krisenereignisse differenziert bewertet werden. Dies führt zu einem besseren Verständnis von Nachhaltigkeit in der Außenpolitik und legt dar, dass sozialkonstruktivistische Außenpolitikforschung in der Lage ist, über die Gegenwart hinaus Aussagen über das zu erwartende Verhalten von Staaten in einem bestimmten Handlungskontext abzugeben.

In Byzantine fault-tolerant (BFT) systems, no concrete assumptions are made about the behavior of faulty replicas. With the advancement of distributed ledger technologies (DLT), planetary-scale BFT SMR ist becoming practical and necessary as it can serve as a consensus primitive to keep the ledger consistent. In our view, the alignment of BFT SMR to DLT brings new challenges, for instance the scalability aspect, where recent research works less frequently address latency improvements than throughput improvements. Further challenges include the geographic dispersion of replicas within a planetary-scale system and the need of a BFT SMR protocol to react to environmental changes during runtime. This thesis has the objective to improve BFT SMR for planetary-scale systems by lowering the protocol latency observed by clients and by making the BFT SMR system adaptive, i.e., enabling replicas to react to perceived changes such as changing network characteristics or faulty replicas. As a first contribution of this thesis, we discover that fast, consensus-free (read-only) operations is a flawed optimization in seminal BFT SMR frameworks, such as PBFT and BFT-SMaRt. We explain how the read-only optimization can violate the protocol's liveness by showing an attack and then present a solution that makes the overall, optimized protocol both live and linearizable. The second contribution is Adaptive Wide-Area Replication (AWARE), which enables a geo-replicated system to adapt to its environment, thus improving the geographical scalability of consensus if replicas are dispersed across the world. Essentially, AWARE is an automated and dynamic voting-weight tuning and leader positioning scheme, which supports the emergence of fast consensus quorums in the system and builds upon previous work, the WHEAT protocol. AWARE combines reliable self-monitoring with a consensus latency prediction model, thus striving to minimize the system’s consensus latency at runtime, which subsequently results in latency improvements observed by clients scattered across the globe, which we validate through experiments. The third contribution presents FlashConsensus, a protocol derived from AWARE, that also adjusts the resilience threshold. The core idea is the tentative use of a lower resilience threshold which leads to smaller consensus quorums and thus consensus acceleration in common-case scenarios where we expect only few faulty replicas. FlashConsensus achieves threat-level awareness through the incorporation of two modes of operation and BFT forensic support and guarantees liveness and linearizability under optimal resilience. Moreover, FlashConsensus allows for client-side speculation by using incremental consistency guarantees to further lower request latency. Additionally, we investigate on the question whether we can reason about the performance of large-scale systems utilizing simulations. We discover, that we can faithfully forecast the performance of BFT protocols by plugging real protocol implementations into a high-performance network simulator. For instance, simulation results reveal that, using 51 replicas scattered across the planet, FlashConsensus can finalize operations in less than 0.4 s, which is half of the time required for a PBFT-like protocol in the same network, and matching the latency of this protocol running on the best possible internet links (transmitting at 67% of the speed of light). N2 - Die Zustandsmaschinenreplikation (ZMR) ist ein klassischer Ansatz für zuverlässige verteilte Systeme. In Byzantinischen fehlertoleranten (BFT) Systemen werden keine konkreten Annahmen über das Verhalten von fehlerhaften Replikaten gemacht. Mit dem Voranschreiten der sog. „Distributed Ledger Technologien“ (DLT) wird planetare BFT ZMR praktikabel und notwendig, da sie als Konsensusprimitiv dienen kann, um die Konsistenz einer Blockchain aufrechtzuerhalten. Unserer Ansicht nach bringt die Ausrichtung von BFT ZMR an DLT neue Herausforderungen mit sich, z.B. den Skalierbarkeitsaspekt, bei dem jüngste Forschungsarbeiten seltener Latenzverbesserungen als Durchsatzverbesserungen untersuchen. Weitere Herausforderungen umfassen die geografische Verteilung von Replikaten innerhalb eines planetaren Systems sowie die Notwendigkeit eines BFT ZMR Protokolls während der Laufzeit auf Veränderungen zu reagieren. Diese Dissertation verfolgt das Ziel, die BFT ZMR für planetare Systeme durch Senkung der von Clients beobachteten Protokolllatenz zu verbessern und die BFT ZMR-Systeme anpassungsfähig zu machen, indem Replikate auf wahrgenommene Änderungen wie sich ändernde Netzwerkcharakteristiken oder fehlerhafte Replikate reagieren können. Als erster Beitrag dieser Dissertation zeigen wir, dass schnelle, konsensusfreie (nur-lesende) Operationen in grundlegenden BFT ZMR Protokollen, wie PBFT und BFT-SMaRt, eine fehlerhafte Optimierung sind. Wir erklären, wie die nur-lesende Optimierung die Liveness (Verfügbarkeit von Operationen) des Protokolls verletzen kann, indem wir einen Angriff präsentieren und dann eine Lösung vorschlagen, die das insgesamt optimierte Protokoll sowohl live (verfügbar) als auch linearisierbar („linearizable“ -- streng konsistent) macht. Der zweite Beitrag ist Adaptive Wide-Area Replication (AWARE), mit der ein geo-repliziertes System sich an seine Umgebung anpassen kann und damit die geografische Skalierbarkeit des Konsensus verbessert, wenn Replikate auf der ganzen Welt verteilt sind. Im Wesentlichen ist AWARE ein automatisches und dynamisches Stimmgewichtseinstellungs- und Anführerpositionierungs-schema, das die Entstehung schneller Konsensusquoren im System unterstützt und auf früheren Arbeiten, wie dem WHEAT-Protokoll, aufbaut. AWARE kombiniert zuverlässige Selbstüberwachung mit einem Konsensuslatenzvorhersagemodell und strebt danach, die Konsensuslatenz des Systems zur Laufzeit zu minimieren, was letztendlich zu Latenzgewinnen führt, die von Clients auf der ganzen Welt beobachtbar sind, was wir durch Experimente bestätigen. Der dritte Beitrag stellt FlashConsensus vor, ein Protokoll, das aus AWARE abgeleitet ist und auch die Resilienzschwelle anpasst. Die Kernidee ist die vorübergehende Verwendung einer niedrigeren Resilienzschwelle, die zu kleineren Konsensusquoren und damit zu einer Beschleunigung des Konsensus in häufigen Fällen führt, in denen nur wenige fehlerhafte Replikate erwartet werden. FlashConsensus erkennt und reagiert auf Bedrohungen durch die Einbeziehung von zwei Betriebsarten und BFT-Forensikunterstützung und garantiert Liveness sowie Konsistenz unter optimaler Resilienz. Darüber hinaus ermöglicht es die Spekulation auf Clientseite durch die Verwendung inkrementeller Konsistenzgarantien, um die Clientlatenz weiter zu senken. Zusätzlich werden wir uns mit der Frage beschäftigen, ob wir die Performanz von groß-skalierten Systemen mittels Simulationen beurteilen können. Wir stellen fest, dass wir die Performanz von BFT Protokollen durch das Einstöpseln von echten Protokollimplementierungen in einen hochleistungsfähigen Netzwerksimulator zuverlässig vorhersagen können. Beispielsweise zeigen Simulationen, dass FlashConsensus mit 51 Replikaten, die auf der ganzen Welt verteilt sind, Operationen in weniger als 0,4 s linearisierbar verarbeiten kann, was die Hälfte der Zeit ist, die für ein PBFT-ähnliches Protokoll im gleichen Netzwerk erforderlich ist und ähnlich schnell ist wie dieses Protokoll mit bestmöglichen Internetverbindungen (Übertragung mit 67% der Lichtgeschwindigkeit).

One key technology that becomes part of this digital transformation is cloud computing. It allows users to have a running system as a virtual machine (VM) on the cloud without owning a physical server. Unfortunately, adversaries can also use those systems to conduct criminal activities. Therefore, developing a method to extract evidence from those systems is also necessary. One way is through digital forensics, and one method to do digital forensics of a VM is using virtual machine introspection (VMI). However, VMI has yet to be made available by any public cloud provider. This thesis addresses this issue by introducing methods for deploying VMI on public cloud providers. Four main challenges have to be solved. Firstly, VMI requires access to the hypervisor, which practically can access all VMs running on the same server. This leads to security and privacy issues where customers can introspect each other VMs. To solve this problem, this thesis introduces KVMIveggur, a versatile access control of VMI. It comes with different options that every customer can choose from based on their needs. Secondly, VMI introduces overhead to the running VM. This is because most of the introspection mechanisms perform data access to the monitored VM. Performing data access on a running VM can cause data inconsistency. Hence, pausing the VM before executing the data access is better. However, when the VM pausing frequency is high, it will affect the performance of the monitored VM. The current state-of-the-art techniques use caching to reduce the VM pausing frequency. However, it faces a problem: the cached data may be outdated compared to the actual data. Therefore, this thesis introduces VMIFresh, a better caching mechanism. We leverage both active and passive tracing mechanisms to ensure high performance and consistency of the data (freshness). Thirdly, many state-of-the-art VMI libraries and applications run perfectly only on Intel processors because Intel CPUs provide the best hardware support for VMI. However, AMD and ARM processors are getting more popular in cloud computing. Thus, it is necessary to retrofit VMI capabilities to support AMD and ARM processors. This thesis describes the requirements to employ VMI on AMD and ARM processors. We also provide the implementation of those requirements. Finally, to do introspection using VMI, it is crucial to have proper symbol information (layout and location of data structures) of the introspected operating system (OS) and user applications. While many existing VMI approaches concentrate primarily on analyzing OS data structures, analyzing user application data often receives no attention. In our approach, we address this gap by focussing on application-level introspection. We have identified several use cases that require this kind of introspection. We focus on cryptographic key extraction for two specific instances: secure shell (SSH) and transport layer security (TLS) by leveraging the power of machine learning techniques to locate those keys in the main memory effectively and efficiently. After we had solved those challenges, we combined a couple of our approaches and introduced two VMI applications: Sarracenia and VMIGuard. Sarracenia is a deception technology that tracks activities done on an SSH session. The main goal of Sarracenia is to attract adversaries away from the production system and learn about their behavior. On the other hand, VMIGuard also monitors the SSH traffic. But, it specifically monitors the activity of any git-related activities. The main goal of VMIGuard is to ensure the integrity of the hosted data from any internal malicious actor.

However, in many contexts, individuals disclose their data primarily for the benefit of others and society, thereby showing a form of prosocial behavior. This dissertation conceptualizes these types of data disclosure as prosocial data disclosures and argues that existing privacy research frameworks, such as the privacy calculus, have not been sufficiently applied in privacy research and need to be reevaluated to fully capture the complexities of prosocial data disclosures. Despite the growing relevance of understanding individuals’ willingness for prosocial data disclosures, existing research in this field is limited. This dissertation consists of four essays that seek to deepen the understanding of the underlying decision-making processes of individuals by exploring the antecedents and investigating strategies that promote prosocial data disclosure. By employing different research methods, including systematic literature reviews, qualitative and quantitative surveys, interviews, workshops, and conjoint analysis, this dissertation contributes to the identification of the multifaceted antecedents of prosocial data disclosure which can be classified into different drivers and barriers. Furthermore, by integrating insights from different disciplines such as behavioral economics, social psychology, and information systems research, this dissertation provides empirical evidence for the use of message framing and the deliberate emphasis on impact uncertainty as two promising strategies in promoting prosocial data disclosure. The findings derived from all four essays inform privacy research and prosocial behavior research about the need for sophisticated theories that are capable of better capturing the complexities of prosocial data disclosure. Additionally, the findings offer practical implications for designing ethically responsible data disclosure practices while respecting individual privacy rights.

Chapter 1 reviews the existing experimental evidence on microfinance. We use this deep literature to highlight challenges in generalizing from empirical research. Chapter 2 and 3 provide empirical insights on the energy access-poverty nexus. We study the long-term adoption of grid electrification and evaluate whether productive use can foster adoption and impact. Chapter 4 addresses data quality, an essential yet often overlooked element in research and policymaking.

Depending on the underlying integration problem we show qualitative and quantitative results, which ensure the asymptotic correctness of an algorithm or provide explicit error bounds. The first problem we consider is Lebesgue integration in the unit cube. We prove that a class of structured randomised integration methods is consistent w.r.t. convergence in mean and probability for any integrable function. Under slightly stronger integrability conditions we show that one also has almost sure convergence for median modified methods. We demonstrate the applicability of our theoretical results by considering randomly shifted lattice rules, randomised (t,d)-sequences, Latin hypercube samples, and randomised Frolov points. Secondly, we study integration w.r.t. probability measures which are available only via their non-normalised density. In this context we investigate Markov chain Monte Carlo methods which satisfy a spectral gap condition and functions which do not need to have a finite second moment. We prove error bounds for the absolute mean error where the rate of convergence is optimal. Illustrative scenarios where our theory is applicable are the random walk Metropolis algorithm as well as slice samplers. Finally, we study so-called adaptive increasingly rare Markov chain Monte Carlo algorithms. Based on a simultaneous Wasserstein contraction assumption we estimate the mean squared error and also prove bounds which characterise the path-wise convergence of the estimator. To demonstrate the applicability of our results we consider a number of examples, among which are doubly intractable distributions.

Primary school education aims at empowering children to participate in and reflect on their environment. Therefore, computer science related contents such as programming are increasingly introduced into primary school curricula. However, this also involves challenges in particular for teachers, who need to familiarise themselves with the new curriculum. As a result, primary school teachers often struggle to help primary school children with their programming issues. Corrective feedback given during the learning process (i. e. formative feedback) can help by promoting cognitive factors such as content knowledge. This thesis therefore aims to support primary school programming education through formative feedback. In order to shed light on different perspectives, both teachers and children participated in the studies in a mixed methods design. Teachers’ challenges and children’s programming issues were explored as a basis for knowing what both target groups struggle with. This was done by conducting content analysis on the challenges and issues collected and using the resulting categories for further quantitative analysis. The effects of different characteristics of feedback on the effectiveness and efficiency of teaching and learning programming were then explained. This was done by asking the teachers and children to explain their ratings and conducting content analysis on their explanations. The support of primary school programming education through formative feedback builds on the major challenge of teachers’ lack of content knowledge and the corresponding strategies of teacher training and automated feedback. Indeed, automated feedback was found to be mostly helpful for debugging and task creation. In order to provide direct support to children, common programming issues were identified in terms of the understanding of programming concepts and the usage of the programming environment. Effects on children’s learning and their preferences were identified for several feedback characteristics, leading for example to elaborated hints instead of simple direct instructions. Based on these results, a formative feedback approach of hint cards was developed and evaluated. The hint cards approach proved to be a useful example strategy for supporting primary school programming education through formative feedback. N2 - Kinder sind in ihrem Alltag zunehmend von informatischen Phänomenen umgeben. Die Grundschulbildung zielt darauf ab, Kinder zu befähigen, an ihrer Umwelt teilzuhaben und sie zu reflektieren. Daher werden informatikbezogene Inhalte wie das Programmieren zunehmend in die Lehrpläne der Grundschulen aufgenommen. Dies bringt jedoch auch Herausforderungen mit sich, insbesondere für die Lehrkräfte, die sich mit dem neuen Lehrplan und Ansätzen vertraut machen müssen. Infolgedessen fällt es Grundschullehrkräften oft schwer, Grundschulkindern bei ihren Programmierproblemen zu helfen. Korrektives Feedback, das während des Lernprozesses gegeben wird (formatives Feedback), kann helfen, indem es kognitive Faktoren wie fachliches Wissen fördert. Ziel dieser Arbeit ist es daher, den Programmierunterricht in der Grundschule durch formatives Feedback zu unterstützen. Um die unterschiedlichen Perspektiven zu beleuchten, nahmen sowohl Lehrkräfte als auch Kinder an den Studien in einem Mixed Methods-Design teil. Die Herausforderungen der Lehrkräfte und die Schwierigkeiten der Kinder bei der Programmierung wurden exploriert, um zu erfahren, womit beide Zielgruppen Probleme haben. Dazu wurden die gesammelten Herausforderungen und Probleme einer qualitativen Inhaltsanalyse unterzogen und die daraus resultierenden Kategorien für eine weitere quantitative Analyse verwendet. Außerdem wurden die Auswirkungen verschiedener Merkmale des Feedbacks auf die Effektivität und Effizienz des Lehrens und Lernens von Programmierkonzepten erklärt. Dazu erläuterten die Lehrkräfte und Kinder ihre Bewertungen und ihre Erläuterungen wurden einer qualitativen Inhaltsanalyse unterzogen. Die Unterstützung des Programmierunterrichts in der Grundschule durch formatives Feedback baut auf der großen Herausforderung des fehlenden fachlichen Wissens der Lehrkräfte und den entsprechenden Strategien der Lehrkräftebildung und des automatischen Feedbacks auf. Das automatische Feedback erwies sich beim Debugging und bei der Erstellung von Aufgaben als hilfreich. Um die Kinder direkt zu unterstützen, wurden allgemeine Programmierprobleme in Bezug auf das Verständnis von Programmierkonzepten und die Nutzung der Programmierumgebung ermittelt. Es wurden Auswirkungen auf das Lernen der Kinder und ihre Präferenzen für verschiedene Feedback-Merkmale ermittelt, was beispielsweise in elaborierten Hinweisen anstelle einfacher direkter Anweisungen resultiert. Auf der Grundlage dieser Ergebnisse wurde ein formatives Feedbackkonzept mit Hinweiskärtchen entwickelt und evaluiert. Dieses Konzept erwies sich als nützliche Strategie zur Unterstützung des Programmierunterrichts in der Grundschule durch formatives Feedback.

Vom Architekturwettbewerb zur gebauten Realität am Campus Passau N2 - In der Praxis wird für den Bildungssektor, insbesondere für Universitäten, bereits nachhaltig gebaut. Häufig kommen hierzu Architekturwettbewerbe als regulierendes Instrument zum Einsatz. In der Theorie jedoch, im Bereich der Architekturgeschichte, wurde dieses Zusammenspiel noch wenig tiefgreifend behandelt. Vor allem, da es sich um ein architekturhistorisch junges Themenfeld handelt. Speziell über die nachhaltige Bauweise am Campus Passau, der erst in den 1970er Jahren im Zuge eines städtebaulichen Ideen- und Bauwettbewerbes entstand und stetig erweitert wird, und deren Wurzeln ist der Öffentlichkeit wenig bekannt. Um diese Informationslücke zu schließen und die Frage zu beantworten, wie Architekturwettbewerbe im Allgemeinen eine nachhaltige Baukultur für Universitäten begünstigen oder sogar festschreiben können, ist die Dissertation „UNIVERSITÄT NACHHALTIG BAUEN“ entstanden. In ihr wird im Zuge der Erforschung der Architekturgeschichte der Universität Passau analysiert, wie Architekturwettbewerbe die Entstehung ihres nachhaltigen Campus etabliert haben und wie sie das auch weiterhin tun. Somit wird ein signifikanter Beitrag zur architektur- sowie insbesondere ideengeschichtlichen Aufarbeitung von Wettbewerbsverfahren als Instrument nachhaltigen Hochschulbaus geleistet. Im Besonderen wird die Identität der Universität Passau als nachhaltige Hochschule über die Darlegung der Tradition klimafreundlichen Bauens am Campus, welche ihren Ursprung in Konkurrenzen hat, gefestigt. Diese exemplarische Entwicklung mit Leitbildcharakter wird erstmals unter Fokussierung auf ein zukunftsweisendes, aktuell sehr präsentes Thema Nachhaltigkeit, zusammenhängend systematisch dokumentiert, analysiert, kontextualisiert sowie kritisch diskutiert. Ziel dieser Vorgehensweise ist es, einen Nachweis fortdauernder nachhaltiger Baukultur, Architektur sowie nachhaltigen Städtebaus am Beispiel des Campus Passau zu erbringen. Untersucht wird die Zeitspanne ab der Gründung anhand der Analyse der entsprechenden Architekturwettbewerbe, mit Schwerpunkt auf das ursprüngliche Verfahren der 70er Jahre für den Campus am Inn bis hin zum aktuellen Verfahren für den Neubau des Internationalen Wissenschaftszentrums am Spitzberg. Die so entstandenen neuen Erkenntnisse bereichern mittels Brückenschlägen zwischen Theorie und Praxis die Nachhaltigkeitsforschung und den bestehenden architekturwissenschaftlichen Diskurs, eröffnen neue Forschungsperspektiven, werden einer breiten Öffentlichkeit erstmals zugänglich gemacht. Sie können unter anderem als Vorbild und unterstützendes Begleitmaterial zukünftiger Planungen dienen. Hervorzuheben ist dabei immer der Fokus auf die historische Entwicklung, architektonische Revolution und Tradition, die zur heutigen Identität des Campus Passau führte. N2 - Sustainable building for education, especially for universities, is already usual in practice. Architectural competitions are therefore frequently used as an instrument of regulation. In the field of history and theory of architecture however, this kind of interaction has rarely been studied profoundly. Particularly, because it is a young theme of architectural history. The sustainable methods of construction for the campus in Passau that was founded in the 1970s by an architectural competition and that grows continuously aren’t well-known in public. Hence this treatise tries to fill this gap and answer the question, how a sustainable building culture can profit form architectural competitions or how it even can be established by them. Because this approach only developed by the intense study of the architectural history of the University of Passau, it shall be analyzed, how architectural competitions have established the birth of a sustainable campus in Passau and how they continue to do so. Thus, a significant contribution to research in architectural history for competition procedures as instrument of a sustainable university architecture can be achieved. Particularly the identity of the University of Passau as sustainable can be revealed by the exploration of the tradition of climate-friendly building on the campus which has its origin in such contests. This exemplary development will be systematically documented, analyzed, contextualized, and critically discussed for the first time with focus on today’s present theme, sustainability. The aim of this procedure is to prove a persisting building culture, architecture as well as sustainable urban planning by the example of the Campus Passau. This period will be examined from the founding by the analysis of the corresponding architectural competitions with main emphasis on the original procedure from the 70s for the campus at the river Inn to the actual process for the new building of the International Centre of Sciences at the Spitzberg. The new achievements should enrich sustainability research and the recent discourse of architectural science in art history. Furthermore, it should open new perspectives of research. The findings should be accessible for the public for the first time. They can be a role model and supporting material for future planning. Meanwhile the focus of this piece of work stays always on the development, tradition and identity of the Campus Passau and its history.

ER - TY - JOUR A1 - Fekih Hassen, Wiem A1 - Challouf, Maher T1 - Long short-term renewable energy sources prediction for grid-management systems based on stacking ensemble model JF - Energies N2 - The transition towards sustainable energy systems necessitates effective management of renewable energy sources alongside conventional grid infrastructure. This paper presents a comprehensive approach to optimizing grid management by integrating Photovoltaic (PV), wind, and grid energies to minimize costs and enhance sustainability. A key focus lies in developing an accurate scheduling algorithm utilizing Mixed Integer Programming (MIP), enabling dynamic allocation of energy resources to meet demand while minimizing reliance on cost-intensive grid energy. An ensemble learning technique, specifically a stacking algorithm, is employed to construct a robust forecasting pipeline for PV and wind energy generation. The forecasting model achieves remarkable accuracy with a Root Mean Squared Error (RMSE) of less than 0.1 for short-term (15 min and one day ahead) and long-term (one week and one month ahead) predictions. By combining optimization and forecasting methodologies, this research contributes to advancing grid management systems capable of harnessing renewable energy sources efficiently, thus facilitating cost savings and fostering sustainability in the energy sector.

A randomized controlled trial with Indonesian Facebook users JF - npj | Digital medicine N2 - Nudging individuals without obvious symptoms of non-communicable diseases (NCDs) to undergo a health screening remains a challenge, especially in middle-income countries, where NCD awareness is low but the incidence is high. We assess whether an awareness campaign implemented on Facebook can encourage individuals in Indonesia to undergo an online diabetes self-screening. We use Facebook’s advertisement function to randomly distribute graphical ads related to the risk and consequences of diabetes. Depending on their risk score, participants receive a recommendation to undergo a professional screening. We were able to reach almost 300,000 individuals in only three weeks. More than 1400 individuals completed the screening, inducing costs of about US$0.75 per person. The two ads labeled “diabetes consequences” and “shock” outperform all other ads. A follow-up survey shows that many high-risk respondents have scheduled a professional screening. A cost-effectiveness analysis suggests that our campaign can diagnose an additional person with diabetes for about US$9.
