Aimed at facilitating the re-use and sharing of data in and between the private and public sectors, the DGA introduces regulation for a newly emerging type of digital platforms - the so-called "providers of data intermediation services". In order to offer their services on the market, providers will have to submit to a prior notification procedure and show compliance with several conditions placed on their economic activities. The regulation of data intermediaries is intended to increase their trustworthiness and ensure the competitiveness of the markets in which they operate. Recent experiences with digital platforms have shown the potential of intermediaries to organise and facilitate markets. At the same time, digital platforms pose undeniable risks to their users and markets at large. Against this backdrop, the role of data intermediaries as envisioned by the DGA must be examined carefully before turning to the question whether the DGA can achieve competitive and trustworthy data sharing through registered third parties. This paper intends to shed light on these and other issues by examining, in-depth, the chapter in the DGA dedicated to data intermediaries (Art. 10-15) from a legal, policy and competition economics perspective. In particular, this paper explores how the experiences made with large-scale digital platforms have shaped the DGA. Thereby, this paper aims to contribute towards a holistic understanding of these provisions as a basis for an informed discussion on the legal framework and on possible alternatives.}, language = {en} } @article{CaspariSadeghi2022, author = {Caspari-Sadeghi, Sima}, title = {Artificial Intelligence in Technology-Enhanced Assessment: A Survey of Machine Learning}, series = {Journal of Educational Technology Systems}, volume = {51}, journal = {Journal of Educational Technology Systems}, number = {3}, publisher = {SAGE Publications}, address = {Sage CA: Los Angeles, CA}, issn = {0047-2395}, doi = {10.1177/00472395221138791}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-11818}, pages = {372 -- 386}, year = {2022}, abstract = {Intelligent assessment, the core of any AI-based educational technology, is defined as embedded, stealth and ubiquitous assessment which uses intelligent techniques to diagnose the current cognitive level, monitor dynamic progress, predict success and update students' profiling continuously.

However, in times of increasing international conflicts and polarisation, such as the years leading up to the Russia's war against Ukraine in 2022, migrant audiences find themselves in a situation when the coverage of national and international politics in the homeland and host country media can differ dramatically. Against this backdrop, this study investigated how Russian speakers living in Germany create and navigate their transnational news repertoires. Grounded in 42 semi-structured interviews with the Russian speakers of the 1 and 1.5 generations in Germany, conducted between May and October 2021, this article identifies three types of transnational news repertoires: (1) politically-motivated news repertoire, (2) truth seeking-motivated news repertoire and (3) situation-motivated news repertoire. The results show that all the news repertoires of all participants are transnational. I argue that in the context of international conflict, not only language but also the participants' political beliefs play an essential role in their news choice.

A deep understanding of the requirements of research data management (RDM), as well as an overview of the different stakeholders, is a key prerequisite for the implementation of an RDMS. Based on a scientific literature review, the aim of this study is to answer the following research questions: "What organizational factors need to be considered when implementing an RDMS? How do these organizational factors interact with each other and how do they constrain or facilitate the implementation of an RDMS?" The structure of the analysis is built on the four components of Leavitt's classical model of organizational change: task, structure, technology, and people. The findings reveal that the implementation of RDMS is strongly impacted by the organizational structure, infrastructure, labor culture as well as strategic considerations. Overall, this literature review summarizes different approaches for the implementation of an RDMS.

Sustained local demand is an essential requirement for further adoption of organic farming by smallholders, who typically have only limited access to export markets. Until now, only few studies have explored the local willingness to pay (WTP) for organic products in low- and middle-income countries in real purchase situations. This paper analyses the consumers' WTP for organic rice in urban and suburban Indonesia using an incentive-compatible auction based on the Becker-DeGroot-Marschak (BDM) approach. We further study the effect of income and a randomised information treatment about the benefits of organic food on respondents' WTP. Estimates suggest that respondents are willing to pay an average price premium of 20\% compared with what they paid for conventional rice outside our experiment. However, our results also indicate that raising consumers' WTP further is complex. Showing participants a video about health or, alternatively, environmental benefits of organic food was not effective in further raising WTP.

Especially at risk are individuals with chronic diseases, since heat can exacerbate a variety of health conditions.

Using a novel dataset from the Indonesian national health insurance scheme Jaminan Kesehatan Nasional/Badan Penyelenggara Jaminan Sosial (BPJS) and linking it with meteorological data on the daily-district level, I estimate the causal effect of high temperatures on the daily number of primary health care visits. The results show that on a hot day all-cause visits and visits with a diagnosis of diabetes and cardiovascular diseases increase by 8\%, 25\% and 14\%, respectively. These increases are permanent and not offset by visit displacement or 'harvesting'. Visits related to respiratory diseases seem not to be affected by high temperatures. I use several climate change scenarios to predict the increase in visits and costs by the end of the century, which all forecast a substantial financial burden for the health care system.

Indeed, a plethora of studies suggest that the performing arts are more than an interesting sideline for authors, as they offer unique theoretical and empirical lenses for organization studies. However, this stream of literature spreads across multiple research areas, varies with regard to its underlying theories and methods, and fails to pay sufficient attention to the contextuality of the findings. We address the resulting limitations by identifying and reviewing 89 articles on management and organization related to the performing arts published in 15 top-tier journals between 1976 and 2022. We find that research in the performing arts advances organizational theory and the understanding of organizational phenomena in four key ways, namely by studying (1) organizational phenomena in performing-arts contexts; (2) performing-arts phenomena in organizational contexts; (3) organizational phenomena through the prism of performing-arts theories; and (4) organizational phenomena through the prism of performing-arts practices. We also find that, in contrast to other settings, the performing arts are uniquely suited for immersive participant-observer research and for generating genuine insights into fundamental organizational structures and processes that are generic conditions of the performing arts and management alike, such as leadership, innovation, and the management of uncertainty.

One quantitative indicator of policy effectiveness and pandemic severity is the case fatality ratio, which relies on the lagged number of infections relative to current deaths. The appropriate length of the time lag to be used, however, is heavily debated. In this article, I contribute to this debate by determining the temporal lag between the number of infections and deaths using daily panel data from Germany's 16 federal states. To account for the dynamic spatial spread of the virus, I rely on different spatial econometric models that allow not only to consider the infections in a given state but also spill over effects through infections in neighboring federal states. My results suggest that a wave of infections within a given state is followed by increasing death rates 12 days later. Yet, if the number of infections in other states rises, the number of death cases within that given state subsequently decreases.

To approach this conundrum, research focus has progressed from an isolated investigation of IT to the assessment of complementarity between IT and different non-IT resources such as work practices or decision structures. However, incoherence around the characteristics and scope of these complementary non-IT resources has created a fragmented body of research, preventing a sustainable knowledge creation. Thus, in this paper we synthesize the dispersed research efforts, identify shortcomings in the extant literature, and derive opportunities for future research. Specifically, we present a converging definition of complementary non-IT resources and specify their role in the value creation process from IT by viewing it through three distinct lenses: microeconomic theory, resource-based view, and contingency theory. We structure current research efforts by organizing complementary non-IT resources into distinct categories, namely strategy, structure, practices, processes, and culture (organizational resources), top management support, internal relations, and external relations (relational resources), worker skill (non-IT human resources), non-IT physical resources, as well as internal funds and external funds (financial resources).

Based on 35 qualitative in-depth inter-views, we identify four barriers that hinder the funding of artistic projects throughICOs: legal shortcomings, investment restrictions, lack of consumer interest, andintermediaries' resistance. Our research contributes to cultural finance and fundingliterature by disclosing barriers that impede a promising form of financing artisticprojects. Further, we outline possible solutions to overcome them. We also con-tribute to the research about ICOs by showing that rather than reducing investmentrisks, these offerings merely shift them.}, language = {en} } @article{Herberger2022, author = {Herberger, Marie}, title = {Pf{\"a}ndungsschutz f{\"u}r Tiere}, series = {Natur und Recht}, volume = {2022}, journal = {Natur und Recht}, number = {44}, publisher = {Springer Nature}, address = {Berlin}, doi = {10.1007/s10357-022-3958-z}, url = {http://nbn-resolving.de/urn:nbn:de:101:1-2022052822431970208748}, pages = {106 -- 109}, year = {2022}, abstract = {Das Gerichtsvollzieherschutzgesetz (GvSchuG) hat den Pf{\"a}ndungsschutz f{\"u}r Tiere erweitert.

In this paper, we define the novel Neural Aggre-gate Generator (NAG), a neural network-based feature extraction module that learns featureaggregates end-to-end on the fraud classification task. In contrast to other automatic featureextraction approaches, the network architecture of the NAG closely mimics the structureof feature aggregates.

We provide a proof to show the modeling capabilities of the NAG.We compare the performance of the NAG to the state-of-the-art approaches on a real-worlddataset with millions of transactions. More precisely, we show that features generated with theNAG lead to improved results over manual aggregates for fraud classification, thus demon-strating its viability to replace them. Moreover, we compare the NAG to other end-to-endapproaches such as the LSTM or a generic CNN. Here we also observe improved results. Weperform a robust evaluation of the NAG through a parameter budget study, an analysis of theimpact of different sequence lengths and also the predictions across days.

However,instead of being bound directly with the response in a binary fashion, the context modulates the binary binding between thedistractor and response. This finding raises the questions of whether the context can also enter into a binary binding with theresponse, and if so, what determines the way of its integration. In order to resolve these questions, saliency of the contextwas manipulated in three experiments by changing the loudness (Experiment 1) and emotional valence (Experiment 2Aand 2B) of the context. All experiments implemented the four-alternative auditory negative priming paradigm introducedby Mayr and Buchner (2006, Journal of Experimental Psychology: Human Perception and Performance, 32[4], 932-943).Results showed that the integration of context changed as a function of its saliency level. Specifically, the context of lowsaliency was not bound at all, the context of moderate saliency modulated the binary binding between the distractor andresponse, whereas the context of high saliency entered into a binary binding with the response. The current results extend aprevious finding by Hommel (2004, Trends in Cognitive Sciences, 8[11], 494-500) that there is a saliency threshold whichdetermines whether a stimulus is bound or not, by suggesting that a second threshold determines the specific structure (i.e.,binary vs. configural) of the resulting binding.}, language = {en} } @misc{KottSchusterGrossetal.2025, author = {Kott, Annette and Schuster, Jennifer and Groß, Rainer and Bauer, Christoph}, title = {Maßnahmenkatalog Green IT an bayerischen Hochschulen}, organization = {Digitalverbund Bayern}, doi = {10.15475/DVB-GIT.2025}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-15327}, pages = {VII, 43 Seiten}, year = {2025}, abstract = {"Der vorliegende Maßnahmenkatalog bietet abgestimmte Empfehlungen, um Nachhaltigkeit f{\"u}r bayerische Hochschulen im Bereich Green IT zu f{\"o}rdern.

By applying a simple propensity score matching approach, the study demonstrates that households with at least one migrant are 18 percentage points more likely to invest in housing for Amedzofe family members than non-migrant housholds. Notably, investments in aesthetically appealing housing are particularly significant. Our qualitative findings substantiate these observations, highlighting a strong inclination to showcase translocal interconnectedness and a lasting sense of belonging to Amedzofe. Housing investments also encapsulate the ingrained notion of migrants' eventual return to Amedzofe, especially for retirement, namely the "stone-made myth of return."

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.}, subject = {R{\"u}ckmeldung}, language = {en} } @phdthesis{Stumpf2024, author = {Stumpf, Peter Frederik}, title = {Partial Representation Extension and Simultaneous Representation of Intersection Graphs}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-15201}, school = {Universit{\"a}t Passau}, pages = {IX, 208 Seiten}, year = {2024}, abstract = {Many real world problems can be modeled with geometric intersection graphs. A (geometric) intersection representation of a graph G=(V,E) is a family {R_v}_{v\in V} of geometric objects such that two geometric objects R_u, R_v intersect if and only if the corresponding vertices u, v are adjacent in G. The most prominent class of intersection graphs are interval graphs, which have representations consisting only of intervals on the real line. Interval graphs have applications in genetics, scheduling, archaeology and many more fields. The recognition problem asks the question whether a given graph belongs to a certain graph class. Two natural generalizations of the recognition problem are the partial representation extension problem and the simultaneous representation problem. In the partial representation extension problem one is given a graph G and a partial representation, i.e., a representation of a subgraph of G. The question then is whether the partial representation can be extended to the whole graph G without changing the given partial representation. In the simultaneous representation problem one is given multiple graphs G_1,...,G_k that can have shared parts, and the question is whether there are representations of all input graphs such that shared vertices are represented by the same geometric objects. Often the sunflower case is considered, where the shared part of any two input graphs is the same. We determine the complexity of the partial representation extension problem and the simultaneous representation problem, especially in the sunflower case for various intersection graph classes. We also improve the running time for various intersection graph classes. In particular, we show that the partial representation extension problem for circular-arc graphs is NP-complete and that the simultaneous representation problem for interval graphs can be solved in linear time in the sunflower case, answering open questions from 2014 and 2010.}, language = {en} } @phdthesis{Grabl2024, author = {Grabl, Susanne}, title = {How Technological Advancements and Digitalization Impact Both Organizational Behavior and Work Structures}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-15149}, school = {Universit{\"a}t Passau}, pages = {IV, 153 Seiten}, year = {2024}, abstract = {Organizations are in a constant state of flux, making transformations an inevitable aspect of their evolution and adaptation (By, 2005; Kotter, 1995). Transformations in organizations take many forms. These include sustainability transformations intended to make organizations more sustainable and fit for the future (Bansal, 2005; Corbett \& Mellouli, 2017; Kim et al., 2017; Robertson \& Barling, 2013). Additionally, transformations can affect day-to-day work and impact working practices (Orlikowski, 2002; Watson-Manheim et al., 2002, 2012). On the one hand, this enables more flexible working conditions through the introduction of hybrid work, for instance (Halford, 2005). On the other hand, new digital transformations, such as platform work (Deng et al., 2016; Deng \& Joshi, 2016; Kittur et al., 2013; Kost et al., 2018), allow organizations to outsource work. Platform work allows users to work completely flexibly and organize their working day according to their needs (Deng et al., 2016; Deng \& Joshi, 2016; Kost et al., 2018). A distinction can be made between different types of platforms. There are platforms that require physical labor, such as Uber (Duggan et al., 2020; M{\"o}hlmann et al., 2021), where transportation trips can be booked, or DoorDash, where food is delivered (Griesbach et al., 2019). Furthermore, there are entirely virtual online platforms. These include freelancing platforms such as Topcoder or Upwork, where workers advertise their profiles for jobs such as web design (Howcroft \& Bergvall-K{\aa}reborn, 2019; Shafiei Gol et al., 2019; Taylor \& Joshi, 2019). They are evaluated by their clients and paid according to their work performance. There is also another type of platform with very low entry barriers: micro-task crowdsourcing platforms (Bush \& Balven, 2021; Deng et al., 2016; Deng \& Joshi, 2016; Wong et al., 2020). Here, people can perform currently posted tasks without prior application and receive a small remuneration (Deng et al., 2016). Digital transformations in the workplace change work processes and practices in the long term (Carroll et al., 2023). For instance, the introduction of hybrid work allows employees to divide their working time between the office and remote locations (Halford, 2005). Studies have shown that this shift has not negatively impacted employee performance, but has actually improved it (Abdullah et al., 2020; Mann \& Holdsworth, 2003; Wessel et al., 2021). Thanks to the gain in flexibility, employees are at least as productive as in mere office work. However, this can also have negative effects, for example on the training of new employees or on maintaining social contacts among colleagues (Hafermalz \& Riemer, 2020; Weritz et al., 2022). Another transformation changing organizations, particularly day-to-day work, is the introduction of artificial intelligence (AI) (Strich et al., 2021). AI encompasses a range of technologies that aim to mimic human cognitive processes or learn independently to solve problems (Asatiani, Malo, et al., 2021; Benbya et al., 2021; Berente et al., 2021). AI differs from previous technologies in terms of its self-learning nature, its (partial) autonomy in decision-making, and its opacity (Asatiani, Malo, et al., 2021; Barredo Arrieta et al., 2020). A special type of AI in use is generative AI (GAI). GAI is a model capable of creating apparently new content such as texts, codes, images, etc. (Brynjolfsson et al., 2023; Susarla et al., 2023). GAI applications like ChatGPT and Bard have quickly gained a large user base due to their easy accessibility, applicability, and versatility (Alavi et al., 2024; Kowalczyk et al., 2023). In addition to private use, GAI is utilized in various work processes across different professions (Benbya et al., 2024; Brynjolfsson et al., 2023), benefiting employees and organizations by improving the quality and efficiency of work (Brynjolfsson et al., 2023; Jia et al., 2024).

Thereby, I contribute to a dynamic field and demonstrate how transformations in organizations can have a lasting impact on work processes.

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.

In completely detached work settings (study two), our findings emphasize the prevalence of negative work experiences - frustration in our case - and the central role of both social and technical antecedents. Work settings devoid of any organizational framework, such as microtask crowd work, show an even greater detachment from shared values and structures compared to study one, posing significant challenges for the workers involved.

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 f{\"u}r zuk{\"u}nftige Stadtentwicklung darstellen k{\"o}nnen. Trotz eher geringer Unterschiede ist es wichtig, diese verschiedenen Sichtweisen zu ber{\"u}cksichtigen, 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 k{\"o}nnen. Im Kontext der globalen Entwicklung hin zu nachhaltigen Verkehrsmitteln und umweltfreundlichen Mobilit{\"a}tsl{\"o}sungen gewinnt die Analyse der Fahrradfreundlichkeit in St{\"a}dten wie Gunzenhausen immer mehr an Relevanz. Die Ergebnisse und die daraus folgenden Erkenntnisse dieser Untersuchung k{\"o}nnen als Grundlage f{\"u}r eine an den Bed{\"u}rfnissen verschiedener Bev{\"o}lkerungsgruppen ausgerichtete Stadtentwicklung dienen. Sowohl die Zukunft des Radfahrens als Verkehrsmittel als auch die Erhaltung und Erweiterung seiner Attraktivit{\"a}t bleiben in Bezug auf die Anpassung st{\"a}dtischer Infrastrukturen weiterhin von Interesse.

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).}, language = {en} } @phdthesis{Hofer2024, author = {Hofer, Denise}, title = {Die Implementierung Inklusiver Begabungsf{\"o}rderung - Eine Interventionsstudie zur Implementierung Inklusiver Begabungsf{\"o}rderung in Niederbayern}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-15065}, school = {Universit{\"a}t Passau}, pages = {315 Seiten}, year = {2024}, abstract = {In der vorliegenden Forschungsarbeit wird das zweij{\"a}hrige Pilotprojekt „BegIN-Begabungsf{\"o}rderung in Niederbayern" wissenschaftlich begleitet.

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.}, subject = {Softwareentwicklung}, language = {en} } @phdthesis{Masselus2024, author = {Masselus, Lise}, title = {Evaluating Poverty Alleviation: Essays on Microfinance, Energy Access and Limits to the Gold Standard in Empirical Economics}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-14981}, school = {Universit{\"a}t Passau}, pages = {145 Seiten}, year = {2024}, abstract = {In my dissertation, I combine topical contributions on microfinance and energy access, two prevalent poverty alleviation policies, with methodological contributions on how empirical economics research can contribute to effective policymaking.

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.

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.}, subject = {Cloud Computing}, language = {en} } @phdthesis{Binder2024, author = {Binder, Alexandra}, title = {Universit{\"a}t nachhaltig bauen.

With a formal definition for structures of neural networks, neural architecture search problems and solution methods can be formulated under a common framework. Both practical and theoretical questions arise from closing the gap between applied neural architecture search and learning theory. Does structure make a difference or can it be chosen arbitrarily? This work is concerned with deep structures of artificial neural networks and examines automatic construction methods under empirical principles to shed light on to the so called ``black-box models''. Our contributions include a formulation of graph-induced neural networks that is used to pose optimisation problems for neural architecture. We analyse structural properties for different neural network objectives such as correctness, robustness or energy consumption and discuss how structure affects them. Selected automation methods for neural architecture optimisation problems are discussed and empirically analysed.

Often, there exist multiple apps for the same purpose, and it is the choice of the end user to pick an appropriate app. Apps that behave unexpected, e.g., crash frequently, are sooner or later replaced, which isundesirable for the companies developing such apps. Thus, it is essential to tests apps properly before they are released onto the market. However, testing manually is often not only too cost-intensive but also too time-consuming in the short development phase, thus an automated solution is preferred. Testing mobile apps automatically received increased attention in the last decade from primarily people in academia, and several testing techniques evolved. One technique that yielded promising results, especially in different domains, is search-based software testing in which a metaheuristic, e.g., a genetic algorithm, is applied to solve an optimisation problem, e.g., test generation. A main objective of test generation is to produce tests that reveal as many faults as possible. This in turn requires the generation of tests that deeply explore the tested app. The core metric to quantify how much code tests cover is the measurement of code coverage, which can be computed at different levels of granularity ranging from determining the fraction of covered activities to a very fine-grained measurement that calculates the percentage of covered lines. This coverage information is then often used to guide the search of the employed metaheuristic. However, current automated test generation approaches produce tests with a rather low code coverage. Thus, a substantial part of tested apps remains unexplored, which in turn misses revealing deeply residing faults. We identified three core issues that are directly related to the generation of low-coverage tests. First, the applicability of current test generators is often limited. This comprises the fact that current state-of-the-art code coverage tools are incapable of instrumenting a substantial number of apps and consequently, test generators cannot utilise detailed coverage information during exploration. In addition, test generators are often only equipped with a primitive set of actions that are insufficient to simulate system events and complex user inputs. Second, the test execution is extremely time-consuming. This includes among other things the overhead associated with executing individual actions, intermediate restart operations as well as fitness evaluations. Since search-based algorithms require a substantial number of test executions to play out their strengths, the slow test execution impedes the effectiveness of the search. Third, the guidance offered by search-based algorithms is often hampered by applying inadequate fitness functions or by using non-representation-specific variation operators. In this thesis we address the problem of low-coverage tests in the Android domain by proposing several enhancements for the three identified core issues. Concerning the applicability problem, we provide the implementation of a robust code coverage tool that is capable of measuring coverage at different levels of granularity and requires no access to the source code. We also propose to include actions that can simulate system events as well as complex user inputs. Regarding the performance issue, we suggest the integration of a surrogate model that is capable of predicting the outcome of individual actions or complete tests over time in order to reduce the overall test execution costs. With respect to the lack of guidance offered by traditional search-based algorithms, we suggest alternative search strategies. In the case of a deceptive fitness landscape, we propose using novelty search algorithms. Alternatively, we suggest utilising estimation of distribution algorithms that require no crossover or mutation perators to sample new tests. While all those enhancements had a positive impact on the Android test generation process, the individual empirical studies highlighted that further research is necessary to unleash the full power of the proposed search-based algorithms. In particular, exploring complex user interfaces meaningfully requires more attention whether by introducing additional actions or by extracting valuable hints to infer reasonable text inputs. In addition, the guidance offered by fitness functions is often limited because they are either designed too coarse at all or do not accurately reflect the search objectives.}, language = {en} } @techreport{BohnenkaemperFussederEmmanouilidisetal.2024, author = {Bohnenk{\"a}mper, Ronja and Fußeder, Christina and Emmanouilidis, Georgios and Emmert, Cornelia and Haberger, Mathias and Hartmann, Nils and Hohlfeldt, Leonie and J{\"a}ckel, Franziska and K{\"o}rber, Janina and Listl, Johannes and Ostendorp, Falk and Pantaleon Osuna, Alvaro and Steinmetzer, Luzie and Thurl, Lena and Ungruhe, Christian and Wagener, Jonas and Wehner, Stefanie}, title = {Socio-economic development and migration in rural Ghana : report from field research in Amedzofe, Volta Region}, number = {3}, editor = {Ungruhe, Christian and Pantaleon Osuna, Alvaro and Wehner, Stefanie}, doi = {10.15475/mitrawa.upa3}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-14865}, pages = {25 Seiten}, year = {2024}, abstract = {Migration plays a significant role in Ghanaian society, particularly in rural areas where its impact is inextricably linked to socio-economic dynamics.

The field research aimed to address a wide range of topics related to rural livelihoods, focusing on migration and translocal aspects of everyday life. Six working groups embarked on a 10-day field research journey, employing mixed methods encompassing both quantitative and qualitative approaches. This extensive fieldwork followed a semester of intensive preparation, ensuring the thoroughness and depth of the study. The survey results were meticulously analysed and presented, providing valuable insights into the patterns, drivers and impacts of migration in the region. Additionally, the findings of the six working groups offered nuanced perspectives on various facets of rural life, including economic activities, social networks, cultural practices, education and gender aspects.

They can even outperform human decision-making in many task domains (Meehl, 1954; Dawes et al., 1989). The prominent defeat of Garry Kasparov, the world champion in chess, in 1997 is a milestone for the potentials of algorithms, increasing the value of IBM's stock increased by \$18 billion (Norvig and Russell, 2010). More recently, universal chatbots such as ChatGPT and the Bing Chatbot Sydney can influence millions of users and provide them answers to a broad range of tasks. 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; {\"O}nkal 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.

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.}, language = {en} } @unpublished{KloepfWehner2024, author = {Kl{\"o}pf, Tobias and Wehner, Stefanie}, title = {Vulnerabilities and capacities : dealing with coastal flooding in Ghana´s Volta Region}, number = {2}, address = {Passau}, doi = {10.15475/mitrawa.upa2}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-14597}, pages = {14 Seiten}, year = {2024}, abstract = {Coastal flooding events pose an existential threat to populations around the world, particularly in the Global South.

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.

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.}, language = {en} } @article{FekihHassenChallouf2024, author = {Fekih Hassen, Wiem and Challouf, Maher}, title = {Long short-term renewable energy sources prediction for grid-management systems based on stacking ensemble model}, series = {Energies}, volume = {2024}, journal = {Energies}, number = {17(13)}, doi = {10.3390/en17133145}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-14649}, pages = {19 Seiten}, year = {2024}, abstract = {The transition towards sustainable energy systems necessitates effective management of renewable energy sources alongside conventional grid infrastructure.

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 {\"A}hnlichkeiten weiterhin im Rahmen des Partizipationsprojekts sowie (3) einer Datensammlung 3 mit einem Fokus auf st{\"a}rkeren Kontrast und Unterschiede hinsichtlich Aktivit{\"a}t, Alter oder Kultur der Akteure bzw. hinsichtlich des (eher) l{\"a}ndlichen bzw. st{\"a}dtischen 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 Durchf{\"u}hrung von Partizipationsprozessen. Anhand dieser drei Gesichtspunkte ergibt sich zudem die Antwort auf die zentrale Forschungsfrage dieser Arbeit, wie Partizipationsprozesse in kommunalen Projekten gestaltet werden k{\"o}nnen, um digitale Formate sowie lokal-regionale Kontexte zu ber{\"u}cksichtigen, und welche Aspekte dabei relevant sind: (1) das analoge Milieu der konkreten (eher) l{\"a}ndlichen bzw. st{\"a}dtischen 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 Atmosph{\"a}re 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 tats{\"a}chlichen oder emotionalen Betroffenheit ausgepr{\"a}gte) 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 Auspr{\"a}gung milieuorientiert (mit der Definition und Analyse des Partizipations-Raums als Kern der Milieuorientierung und der Standortsuche als zus{\"a}tzlicher Aspekt bei standortbezogenen Projekten), akteursorientiert (auf den Umfang und den Grad der Einflussnahme-M{\"o}glichkeit der Akteure/Interessensgruppen von Nicht-Partizipation {\"u}ber 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 Verst{\"a}ndnis von Partizipationsprozessen erweitert, indem sie die Fokussierung auf gesellschaftliche Interaktionen in st{\"a}dtisch- und l{\"a}ndlich-digitalen Kontexten einf{\"u}hrt, 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 M{\"o}glichkeiten analoger und/oder digitaler Partizipation bei. Schließlich er{\"o}ffnet diese Arbeit Ankn{\"u}pfungspunkte f{\"u}r k{\"u}nftige Forschungen - etwa in der Motivationspsychologie, der Kommunikations- und Politikwissenschaft, der Volkswirtschafts- oder der Betriebswirtschaftslehre sowie mit Blick auf andere r{\"a}umliche Maßst{\"a}be bis hin zu landes-, bundes- und europa-politischen (Partizipations-)Projekten.}, subject = {E-Partizipation}, language = {de} } @phdthesis{Vogelsang2024, author = {Vogelsang, Irina}, title = {Ausstellungen und ihr Erfolg: (Kunst-)Geschichten befragen.

Die Arbeit kombiniert eine ausf{\"u}hrliche 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 Pers{\"o}nlichkeit Indonesiens, Raden Saleh, in den Mittelpunkt. Besonders bemerkenswert war, dass seine Werke erstmals retrospektiv mit Originalgem{\"a}lden in seiner Heimat gezeigt wurden. Die Ausstellung f{\"u}hrte neue Narrative, neu Ausstellungs- und Vermittlungskonzepte ein und weckte großes Interesse beim Publikum, was zu einem außerordentlichen Erfolg f{\"u}hrte. 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 Sph{\"a}re der Kunstdistribution und informellen Bildung in Indonesien leistet die Arbeit einen wichtigen Beitrag zur Grundlagenforschung der S{\"u}dostasienwissenschaften. Gleichzeitig adressiert sie verschiedene Desiderate in der Publikumsforschung und liefert Erkenntnisse f{\"u}r eine kritische Ausstellungspraxis auf internationaler B{\"u}hne. Unter der Ber{\"u}cksichtigung von vielf{\"a}ltigen Kontexten der Ausstellungsbesucher (Sozio-kulturell, physisch, pers{\"o}nlich) 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 pers{\"o}nlichen Bed{\"u}rfnisse an. Gleichzeitig generierte sich das Interesse aus bis dato fehlenden Ganzk{\"o}rpererfahrungen mit historischen Zeitzeugnissen zu Raden Saleh. Der Ausstellungserfolg war nicht nur auf den richtigen Ort, sondern auf den gut gew{\"a}hlten Zeitpunkt zur{\"u}ckf{\"u}hren. 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 F{\"a}higkeit an die oben genannten Kontexte der Besucher_innen anzukn{\"u}pfen oder diese f{\"u}r 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.}, subject = {Rezeptionsforschung}, language = {de} } @phdthesis{Donner2024, author = {Donner, Eva Katharina}, title = {4 Essays on Sustainable Development and Organizations' Response to Stakeholder's Expectations}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-14516}, school = {Universit{\"a}t Passau}, pages = {181 Seiten}, year = {2024}, abstract = {As integral part of the society, environment, and economy, the organization's survival and growth depend on legitimacy which reflects the social support and acceptance of its stakeholders, the institutions and individuals it interacts with. 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.

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.}, language = {en} } @phdthesis{Klumpp2024, author = {Klumpp, Lorenz}, title = {Populismus und Medien - Visuelle Darstellungen politischer Akteure auf Magazincovern}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-14349}, school = {Universit{\"a}t Passau}, pages = {128 Seiten}, year = {2024}, abstract = {Bislang beschr{\"a}nkte sich die inhaltsanalytische Populismusforschung {\"u}berwiegend auf textuelle Botschaften, wie etwa Parteiprogramme, Zeitungsartikel oder Online Foren.

Hinsichtlich des Bereichs Textverstehen konnte ein aus fachspezifischer Perspektive vielversprechendes Modell literarischer Kompetenz auf semiotischer Grundlage (Schilcher \& Pissarek, 2015) in diesem Kontext erstmals im hochschulischen Vermittlungsprozess empirisch untersucht werden. Hier konnten insbesondere hinsichtlich der Kategorien Raum, Figur und Handlung positive Effekte auf die Textverstehensleistung Studierender festgestellt werden. Eine grunds{\"a}tzliche {\"U}berlegenheit des literatursemiotischen Modells konnte aber nicht best{\"a}tigt werden. Die Befunde weisen darauf hin, dass das literatursemiotische Modell hinsichtlich einiger zentraler Teilkompetenzen im Textverstehen f{\"o}rderlich sein kann, dass die Studierenden aber im Professionalisierungsprozess in diesem Bereich wom{\"o}glich noch gezielterer F{\"o}rderung bed{\"u}rfen, um hier Expertise aufzubauen.

Nevertheless, according to the GDPR (General Data Protection Regulation), the organizations have to protect collected data. Access Control (AC) mechanisms are traditionally used to secure information systems against unauthorized access to sensitive data. The increased availability of personal sensor data, thanks to IoT-oriented applications, motivates new services to offer insights about individuals. Consequently, data mining algorithms have been proposed to infer personal insights from collected sensor data. Although they can be used for genuine purposes, attackers can leverage those outcomes, combining them with other type of data, and further breaching individuals' privacy. Thus, bypassing AC mechanisms thanks to such insights is a concrete problem. We propose an inference detection system based on the analysis of queries issued on a sensor database. The knowledge obtained through these queries, and the inference channels corresponding to the use of data mining algorithms on sensor data to infer individual information, are described using Raw sensor data based Inference ChannEl Model (RICE-M). The detection is carried out by RICE-M based inference detection System (RICE-Sy). RICE-Sy considers at the time of the query, the knowledge that a user obtains via a new query and has obtained via his query history, and determines whether this is sufficient to allow that user to operate a channel. Thus, privacy protection systems can take advantage of the inferences detected by RICE-Sy, taking into account individuals' information obtained by the attackers via a database of sensors, to further protect these individuals.}, language = {en} } @phdthesis{Le2022, author = {Le, Mirjam}, title = {The Peri-urban City: Cargo Cult Urbanism, Porosity and an Emerging Urban Citizenship in Vietnamese Secondary Cities}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-14097}, school = {Universit{\"a}t Passau}, pages = {xiii, 241 Seiten}, year = {2022}, abstract = {The impact of urban development on local residents in the urban periphery oscillates between processes of empowerment and processes of marginalization as well as between state-controlled order and decentralized self-organization. Consequently local authorities, including urban planners and local residents need to negotiate their respective roles in the production and usage of urban space defined by transition, transformation and ambiguity. Therefore, this work examines the underlying patterns, interactions and structures which define the negotiation of state-society relations in the framework of a porous peri-urban landscape in Vietnam's secondary cities. In Chapter 1, peri-urban areas are defined as space of transformation where pattern of rural land use are intertwined with pattern of urban land use to create an urban-rural interface with blurred boundaries. The main characteristic of the spatial pattern in Tam Kỳ and Bu{\^o}n Ma Thuột is rooted urban porosity leading to the spatial intertwining of rural, peri-urban and urban spaces. The emerging urban landscape can be defined as peri-urban city. Three main themes define this peri-urban city beyond porosity: (1) processes of transformation creating the peri-urban city, (2) networks of power and control as means to adapt to these transformations and (3) mobility as prerequisite for ability to benefit from the changing landscape in peri-urban cities. Chapter 2 describes how state authorities, urban planners and private investors at the local level in Tam Kỳ and Bu{\^o}n Ma Thuột use porous space to reproduce the city based on their aspirations. This leads to a cargo cult urbanism, where urban planning is rooted in future aspirations for the city. Plans and construction efforts reference the image of a modern urban future and produce the image of a city, which does not exists in the real urban space of Tam Kỳ and Bu{\^o}n Ma Thuột. In the meantime, practices based in peri-urban space are often contradictory to the official aspirations of local state authorities Chapter 3 explores this emerging divergence between the aspired urban space by the state and the reality of urban space rooted in material and social porosity. Traditional, newly accessible and environmental porosity provide an array of accessible space which transforms the peri-urban city into a social arena of encounters and interaction. Consequently, porosity enables local residents to maintain urban space as commons. This counters the push towards the privatization of urban space by state and private actors and creates multiple aspirations for the urban future. Rooted in urban space as commons, porosity enables the usage of peri-urban space as spaces of resistance as discussed in Chapter 4. Mobility and interaction are means of reproduction in the porous ambiguity of urban materiality but also become means of everyday resistance. The emerging spatialities of emancipation provide opportunities for an emerging urban citizenship.

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.

This study aims to understand the role of translocal practices of remittances and visits by migrants on the MTS. Using multi-sited, sequential explanatory mixed methods and the lens of socioecological systems, the study shows that social capital and socioeconomic obligations of cash remittances from, as well as visits by migrants to their communities of origin play positive roles on reforestation under the MTS. Specifically, translocal households have access to, and use remittances to engage relatively better in the MTS than households that do not receive remittances.

A crucial challenge for charging stations arises from matching fluctuating power supplies and meeting peak load demand. The overall objective of this paper is to optimize the charging scheduling of a hybrid energy storage system (HESS) for EV charging stations while maximizing PV power usage and reducing grid energy costs. This goal is achieved by forecasting the PV power and the load demand using different deep learning (DL) algorithms such as the recurrent neural network (RNN) and long short-term memory (LSTM). Then, the predicted data are adopted to design a scheduling algorithm that determines the optimal charging time slots for the HESS. The findings demonstrate the efficiency of the proposed approach, showcasing a root-mean-square error (RMSE) of 5.78\% for real-time PV power forecasting and 9.70\% for real-time load demand forecasting.
