These changes mostly affect the Controller to achieve GDPR-compliant privacy policies and management.However, measures to give users a better understanding of privacy, which is essential to generate legitimate interest in the Controller, are often skipped. We recommend addressing this issue by the usage of privacy preference languages, whereas users define rules regarding their preferences for privacy handling. In the literature, preference languages only work with their corresponding privacy language, which limits their applicability. In this paper, we propose the ConTra preference language, which we envision to support users during privacy policy negotiation while meeting current technical and legal requirements. Therefore, ConTra preferences are defined showing its expressiveness, extensibility, and applicability in resource-limited IoT scenarios. In addition, we introduce a generic approach which provides privacy language compatibility for unified preference matching.}, language = {en} } @misc{OPUS4-1154, title = {Universit{\"a}tsbibliothek Passau: Jahresbericht 2021}, address = {Passau}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-11549}, year = {2022}, abstract = {Jahresbericht der Universit{\"a}tsbibliothek Passau f{\"u}r das Jahr 2021.}, language = {de} } @techreport{Weithmann2022, author = {Weithmann, Michael}, title = {Die Petschenegen.

There are different approaches, each with its own advantages and drawbacks. A promising approach using Delaunay configurations and simplex splines is due to Neamtu. After recalling fundamentals of univariate splines, simplex splines, and the wellknown, multivariate DMS-splines, we address Neamtu's DCB-splines. He defined two variants that we refer to as the nonpooled and the pooled approach, respectively. Regarding these spline spaces, we contribute the following results. We prove that, under suitable assumptions on the knot set, both variants exhibit the local finiteness property, i.e., these spline spaces are locally finite-dimensional and at each point only a finite number of basis candidate functions have a nonzero value. Additionally, we establish a criterion guaranteeing these properties within a compact region under mitigated assumptions. Moreover, we show that the knot insertion process known from univariate splines does not work for DCB-splines and reason why this behavior is inherent to these spline spaces. Furthermore, we provide a necessary criterion for the knot insertion property to hold true for a specific inserted knot. This criterion is also sufficient for bivariate, nonpooled DCB-splines of degrees zero and one. Numerical experiments suggest that the sufficiency also holds true for arbitrary spline degrees. Univariate functions can be approximated in terms of splines using the Schoenberg operator, where the approximation error decreases quadratically as the maximum distance between consecutive knots is reduced. We show that the Schoenberg operator can be defined analogously for both variants of DCB-splines with a similar error bound. Additionally, we provide a counterexample showing that the basis candidate functions of nonpooled DCB-splines are not necessarily linearly independent, contrary to earlier statements in the literature. In particular, this implies that the corresponding functions are not a basis for the space of nonpooled DCB-splines.}, subject = {Spline}, language = {en} } @phdthesis{Mini2022, author = {Mini, Tobias}, title = {An Exploration of Tensions in Centralized and Decentralized Digital Platform Contexts}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-11322}, school = {Universit{\"a}t Passau}, pages = {vi, 154 Seiten}, year = {2022}, abstract = {Digital platforms consist of technical elements such as software and hardware and associated social elements such as organizational processes and standards. When such social or technical elements seem logical individually but inconsistent when juxtaposed they form tensions. Prior research on platforms often focused on individual elements of digital platforms but neglected possible related and conflicting elements which offers limited insight about underlying tensions. While some studies on platforms considered tensions, they largely assumed that centralized platform owners being responsible for responding to tensions, neglecting collective response mechanisms in blockchain-based decentralized autonomous organizations (DAOs) where decentralized participants typically respond to tensions. The examination of tensions in the context of centralized platforms and decentralized autonomous organizations offers an opportunity to surface conflicting elements that form novel types of socio-technical tensions which require collective and technology-enabled response mechanisms. This thesis explored what tensions exist in centralized and decentralized digital platform contexts and how platform participants can respond to selected tensions. For this purpose, this thesis comprises five essays that employ multiple different research methods including interviews analyzed by using techniques of grounded theory, qualitative meta-analysis of published case studies, and systematic literature reviews. The findings derived from all five essays contribute to a better understanding of tensions in digital platforms. In particular, this thesis (1) offers a lens for analyzing platforms as collective organizations in which tensions arise at the collective meta-organizational level requiring collective responses, (2) identifies new tensions and response mechanisms related to generativity and collectivity, and (3) points to a novel category of socio-technical tensions that are especially salient in digital platforms.}, language = {en} } @article{WolffPecikiewicz2022, author = {Wolff, Hannes and Pecikiewicz, Jana}, title = {Enhancement mit Gehirnorganoiden - Ethische und rechtliche Probleme einer terra nova}, series = {Medizinrecht}, volume = {2022}, journal = {Medizinrecht}, number = {40}, publisher = {Springer Nature}, address = {Berlin}, doi = {10.1007/s00350-022-6333-4}, url = {http://nbn-resolving.de/urn:nbn:de:101:1-2023021209214076051248}, pages = {907 -- 917}, year = {2022}, abstract = {Enhancement - ein Begriff, der zwar im Alltag noch nicht in aller Munde ist, aber dennoch seit geraumer Zeit große Beachtung in der Wissenschaft findet. {\"U}bersetzt bedeutet Enhancement „Steigerung" oder „Verbesserung" und setzt dort an, wo Behandlungen {\"u}ber das medizinisch Notwendige hinausgehen.

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} } @article{Ryzhova2022, author = {Ryzhova, Anna}, title = {Motivated by political beliefs, not only by language: How Russian speakers in Germany compose their transnational news repertoires}, series = {Journalism}, volume = {25}, journal = {Journalism}, number = {1}, publisher = {Sage}, address = {Thousand Oaks}, doi = {10.1177/14648849221130557}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-15485}, pages = {218 -- 237}, year = {2022}, abstract = {Extant research in media and migration has been largely apolitical, focusing on how migrants use media to culturally connect with their homeland and keep their family ties.

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.

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.

Thus, in this paper we synthesize the dispersed research efforts, identify shortcomings in the extant literature, and derive opportunities for future research.

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).

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.

We examine initial trust (cognitive trust and behaviour) as well as its development after performance feedback by conducting an online experiment that asked participants to forecast the expected demand for a product. Advice accuracy was manipulated by ± 5 \% relative to the participant's initial forecasting accuracy determined in a pre-test. Results show that initial behaviour towards algorithmic advice is not influenced by cognitive trust. Furthermore, the decision maker's initial forecasting accuracy indicates a threshold between near-perfect and bad advice.

Yet, the integration of Distributed Renewable Energy Sources (DRESs) in the Smart Grid introduces new challenges with regards to electrical grid balancing and storing of electrical energy, as well as additional monetary costs. Furthermore, the future smart grid also has to take over the provision of Ancillary Services (ASs). In this paper, a distributed ICT infrastructure to solve such challenges, specifically related to ASs in future Smart Grids, is described. The proposed infrastructure is developed on the basis of the Smart Grid Architecture Model (SGAM) framework, which is defined by the European Commission in Smart Grid Mandate M/490. A testbed that provides a flexible, secure, and low-cost version of this architecture, illustrating the separation of systems and responsibilities, and supporting both emulated DRESs and real hardware has been developed. The resulting system supports the integration of a variety of DRESs with a secure two-way communication channel between the monitoring and controlling components. It assists in the analysis of various inter-operabilities and in the verification of eventual system designs. To validate the system design, the mapping of the proposed architecture to the testbed is presented. Further work will help improve the architecture in two directions; first, by investigating specific-purpose use cases, instantiated using this more generic framework; and second, by investigating the effects a realistic number and variety of connected devices within different grid configurations has on the testbed infrastructure.}, language = {en} } @techreport{AzcuyBecquerHeinrich2023, author = {Azcuy Becquer, Claudia and Heinrich, Horst-Alfred}, title = {Data documentation on history visualisations on the covers of all issues of Der Spiegel between 1965 and 2021}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-12678}, pages = {126 Seiten}, year = {2023}, abstract = {To answer the research question, all SPIEGEL covers from 1965 to 2021 were examined for a reference to history topics.

Lassen sich positive Zusammenh{\"a}nge zwischen Aufgabenmerkmalen und aufgabenbezogenem situationalem Interesse von Sch{\"u}lerinnen und Sch{\"u}lern herstellen?

Aufgrund haupts{\"a}chlich normativ gesetzter geschichtsdidaktischer Vorschl{\"a}ge zur Lernaufgabengestaltung fehlt bislang ein empirisch {\"u}berpr{\"u}ftes Klassifikationsschema zur Beschreibung von unterschiedlichen Aufgabenmerkmalen. Die vorliegende Studie stellt die Entwicklung eines Aufgabenkategoriensystems vor und untersucht den Zusammenhang zwischen Aufgabenmerkmalen und aufgabenspezifischem situationalem Interesse [Aufgabeninteressantheit (AI) und subjektive Bedeutsamkeit (SB)] von Lernenden. Als Aufgabenmerkmale ließen sich ‚Aufgabenschwierigkeit', ‚Offenheit der Aufgabenstellung' (Aufgabenstruktur), ‚Kognitive Anforderungen', ‚Lebensweltbezug', ‚Oberfl{\"a}chenmerkmale' (grafische Elemente) und ‚Aufgabenumfang' (Leseaufwand und Schreibaufwand) feststellen und wurden hinsichtlich AI und SB n{\"a}her untersucht. Es wurden insgesamt 801 bayerische Realsch{\"u}lerinnen und Realsch{\"u}ler (30 Klassen) der 9. Jahrgangsstufe dreimal innerhalb eines Zeitraums von zwei bis drei Wochen im Rahmen eines lernaufgabengesteuerten Unterrichts befragt. Nach {\"U}berpr{\"u}fung des Klassifikationsschemas zeigten multiple Regressionsanalysen, dass in den Einzelanalysen (Betrachtung der einzelnen Aufgabenmerkmale) AI vorwiegend durch schwierige Aufgaben, wenig strukturierte Aufgaben, Aufgaben mit hohen kognitiven Anforderungen sowie Aufgaben mit reiner Textdarstellung und hohem Lese- und Schreibaufwand vorhergesagt wurde, w{\"a}hrend SB nur durch Aufgaben mit Lebensweltbezug und Aufgaben mit hohem Leseaufwand pr{\"a}diziert wurde. Betrachtet man die Gesamtmodelle (Aufnahme aller Aufgabenmerkmale ins Modell) unter Ber{\"u}cksichtigung von Multikollinearit{\"a}t, zeigten sich positive Effekte auf SB bei Aufgaben mit dem Erfordernis eines historischen Werturteils, das ein In-Beziehung-Setzen des historischen Geschehens mit der eigenen Gegenwart impliziert. Hinsichtlich AI und SB zeigten sich positive Effekte bei Aufgaben mit hohem Leseaufwand. Negative Effekte auf AI ließen sich bei schwierigen Aufgaben und Aufgaben mit hohem Schreibaufwand feststellen. Hinsichtlich AI und SB zeigten sich negative Effekte bei Aufgaben mit reiner Textdarstellung. Der signifikant positive Einfluss von Aufgaben mit hohem Leseaufwand auf AI und SB deutet auf einen Pr{\"a}diktor hin, der Ans{\"a}tze f{\"u}r Nachfolgestudien im Fach Geschichte bietet.

Due to this development, consumers are confronted with decisions to disclose personal data on a daily basis, and have become increasingly intentional about data sharing. While this reluctance to disclose personal data poses challenges for firms, at the same time, it also creates new opportunities for improving privacy-related interactions with customers. This dissertation advocates for a more holistic perspective on consumers' privacy-related decision-making and introduces the consumer privacy journey consisting of three subsequent phases: pre data disclosure, data disclosure, post data disclosure. In three independent essays, I stress the importance of investigating data requests (i.e., the first step of this journey) as they represent a largely neglected, yet, potentially powerful means to influence consumers' decision-making and decision-evaluation processes. Based on dual-processing models of decision-making, this dissertation focuses on both consumers' cognitive and affective evaluations of privacy-related information: First, Essay 1 offers novel conceptualizations and operationalizations of consumers' perceived behavioral control over personal data (i.e., cognitive processing) in the context of Artificial Intelligence (AI)-based data disclosure processes. Next, Essay 2 examines consumers' cognitive and affective processing of a data request that entails relevance arguments as well as relevance-illustrating game elements. Finally, Essay 3 categorizes affective cues that trigger consumers' affective processing of a data request and proposes that such cues need to fit with a specific data disclosure situation to foster long-term decision satisfaction. Collectively, my findings provide research and practice with new insights into consumers' privacy perceptions and behaviors, which are particularly valuable in the context of complex, new (technology-enabled) data disclosure situations.}, language = {en} } @article{UrhahneWijnia2023, author = {Urhahne, Detlef and Wijnia, Lisette}, title = {Theories of Motivation in Education: an Integrative Framework}, series = {Educational Psychology Review}, volume = {35}, journal = {Educational Psychology Review}, number = {2}, publisher = {Springer Nature}, address = {Berlin}, doi = {10.1007/s10648-023-09767-9}, url = {http://nbn-resolving.de/urn:nbn:de:101:1-2023092911454443208560}, pages = {1 -- 35}, year = {2023}, abstract = {Several major theories have been established in research on motivation in education to describe, explain, and predict the direction, initiation, intensity, and persistence of learning behaviors. The most commonly cited theories of academic motivation include expectancy-value theory, social cognitive theory, self-determination theory, interest theory, achievement goal theory, and attribution theory. To gain a deeper understanding of the similarities and differences among these prominent theories, we present an integrative framework based on an action model (Heckhausen \& Heckhausen, 2018). The basic model is deliberately parsimonious, consisting of six stages of action: the situation, the self, the goal, the action, the outcome, and the consequences. Motivational constructs from each major theory are related to these determinants in the course of action, mainly revealing differences and to a lesser extent commonalities. In the integrative model, learning outcomes represent a typical indicator of goal-directed behavior. Associated recent meta-analyses demonstrate the empirical relationship between the motivational constructs of the six central theories and academic achievement.

Understanding the choice between the approaches is important for two reasons. First, the added value of each approach depends on how much is known about the phenomenon of interest at the time of the analysis. Second, because of the specializations of methods, there are benefits to a division of labor between researchers who have expertise in the application of a given method. In this preregistered study, we test two hypotheses that follow from these arguments. We theorize that exploratory research is chosen when little is known about a phenomenon and a confirmatory approach is taken when more knowledge is available. A complementary hypothesis is that quantitative researchers opt for confirmatory designs and qualitative researchers for exploration because of their academic socialization. We test the hypotheses with a survey experiment of more than 900 political scientists from the United States and Europe. The results indicate that the state of knowledge has a significant and sizeable effect on the choice of the approach.

While frequently used, the distinction suffers from a number of shortcomings that have hitherto been devoted little attention to. This dissertation aims to contribute to fill this research gap by systematically addressing these pitfalls. Notably, it does not abandon the binary distinction as such, but aims to further refine it. Thoroughly revisiting the nationalism-patriotism distinction, it synthesises the field's two predominant research traditions, i.e. the work of Kosterman and Feshbach (1989) in the U.S. and the one of Blank and Schmidt (2003) in Germany, that have not been brought into dialogue. In so doing, and engaging with research on attachment, it calls for a more nuanced triad of attachments: nationalism, that revolves around the nation; patriotism, that refers to the homeland; and democratic patriotism with democracy as its object of attachment. In line with this triad, it introduces a novel three-factor measurement model that has been validated in three studies in Germany. Overall, the dissertation underlines the need to approach ambiguous and complex concepts such as nationalism and patriotism in a more theoretically consistent way before operationalizing them in a rigorous manner.}, language = {en} } @phdthesis{Fink2023, author = {Fink, Simon Dominik}, title = {Constrained Planarity Algorithms in Theory and Practice}, doi = {10.15475/cpatp.2024}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-13817}, school = {Universit{\"a}t Passau}, pages = {216 Seiten}, year = {2023}, abstract = {In the constrained planarity setting, we ask whether a graph admits a crossing-free drawing that additionally satisfies a given set of constraints. These constraints are often derived from very natural problems; prominent examples are Level Planarity, where vertices have to lie on given horizontal lines indicating a hierarchy, Partially Embedded Planarity, where we extend a given drawing without modifying already-drawn parts, and Clustered Planarity, where we additionally draw the boundaries of clusters which recursively group the vertices in a crossing-free manner. In the last years, the family of constrained planarity problems received a lot of attention in the field of graph drawing. Efficient algorithms were discovered for many of them, while a few others turned out to be NP-complete. In contrast to the extensive theoretical considerations and the direct motivation by applications, only very few of the found algorithms have been implemented and evaluated in practice. The goal of this thesis is to advance the research on both theoretical as well as practical aspects of constrained planarity. On the theoretical side, we consider two types of constrained planarity problems. The first type are problems that individually constrain the rotations of vertices, that is they restrict the counter-clockwise cyclic orders of the edges incident to vertices. We give a simple linear-time algorithm for the problem Partially Embedded Planarity, which also generalizes to further constrained planarity variants of this type. The second type of constrained planarity problem concerns more involved planarity variants that come down to the question whether there are embeddings of one or multiple graphs such that the rotations of certain vertices are in sync in a certain way. Clustered Planarity and a variant of the Simultaneous Embedding with Fixed Edges Problem (Connected SEFE-2) are well-known problems of this type. Both are generalized by our Synchronized Planarity problem, for which we give a quadratic algorithm. Through reductions from various other problems, we provide a unified modelling framework for almost all known efficiently solvable constrained planarity variants that also directly provides a quadratic-time solution to all of them. For both our algorithms, a key ingredient for reaching an efficient solution is the usage of the right data structure for the problem at hand. In this case, these data structures are the SPQR-tree and the PC-tree, which describe planar embedding possibilities from a global and a local perspective, respectively. More specifically, PC-trees can be used to locally describe the possible cyclic orders of edges around vertices in all planar embeddings of a graph. This makes it a key component for our algorithms, as it allows us to test planarity while also respecting further constraints, and to communicate constraints arising from the surrounding graph structure between vertices with synchronized rotation. Bridging over to the practical side, we present the first correct implementation of PC-trees. We also describe further improvements, which allow us to outperform all implementations of alternative data structures (out of which we only found very few to be fully correct) by at least a factor of 4. We show that this yields a simple and competitive planarity test that can also yield an embedding to certify planarity. We also use our PC-tree implementation to implement our quadratic algorithm for solving Synchronized Planarity. Here, we show that our algorithm greatly outperforms previous attempts at solving related problems like Clustered Planarity in practice. We also engineer its running time and show how degrees of freedom in the theoretical algorithm can be leveraged to yield an up to tenfold speed-up in practice.}, language = {en} } @techreport{EckhardtFreilingHerrmannetal.2023, author = {Eckhardt, Dennis and Freiling, Felix and Herrmann, Dominik and Katzenbeisser, Stefan and P{\"o}hls, Henrich C.}, title = {Sicherheit in der Digitalisierung des Alltags: Definition eines ethnografisch-informatischen Forschungsfeldes f{\"u}r die L{\"o}sung allt{\"a}glicher Sicherheitsprobleme}, doi = {10.15475/sidial.2023}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-13721}, pages = {18 Seiten}, year = {2023}, abstract = {In den vergangenen Jahrzehnten hat es un{\"u}bersehbar zahlreiche Fortschritte im Bereich der IT-Sicherheitsforschung gegeben, etwa in den Bereichen Systemsicherheit und Kryptographie.

Alternatively, smart flexibility management that controls user assets can help to better utilize the existing power grid infrastructure for example by sharing available grid capacity among connected electric vehicles or by disaggregating flexibility requests to hybrid photovoltaic battery energy storage systems in households. Besides maintaining an acceptable state of the power distribution grid, these smart grid applications also need to ensure a certain quality of service and provide fairness between the individual participants, both of which are not extensively discussed in the literature. This thesis investigates two smart grid applications, namely electric vehicle charging-as-a-service and flexibility-provision-as-a-service from distributed energy storage systems in private households. The electric vehicle charging service allocation is modeled with distributed queuing-based allocation mechanisms which are compared to new probabilistic algorithms. Both integrate user constraints (arrival time, departure time, and energy required) to manage the quality of service and fairness. In the queuing-based allocation mechanisms, electric vehicle charging requests are packetized into logical charging current packets, representing the smallest controllable size of the charging process. These packets are queued at hierarchically distributed schedulers, which allocate the available charging capacity using the time and frequency division multiplexing technique known from the networking domain. This allows multiple electric vehicles to be charged simultaneously with variable charging currents. To achieve high quality of service and fairness among electric vehicle charging processes, dynamic weights are introduced into a weighted fair queuing scheduler that considers electric vehicle departure time and required energy for prioritization. The distributed probabilistic algorithms are inspired by medium access protocols from computer networking, such as binary exponential backoff, and control the quality of service and fairness by adjusting sampling windows and waiting periods based on user requirements. The second smart grid application under investigation aims to provide flexibility provision-as-a-service that disaggregates power flexibility requests to distributed battery energy storage systems in private households. Commonly, the main purpose of stationary energy storage is to store energy from a local photovoltaic system for later use, e. g., for overnight charging of an electric vehicle. This is optimized locally by a home energy management system, which also allows the scheduling of external flexibility requests defined by the deviation from the optimal power profile at the grid connection point, for example, to perform peak shaving at the transformer. This thesis discusses a linear heuristic and a meta heuristic to disaggregate a flexibility request to the single participating energy management systems that are grouped into a flexibility pool. Thereby, the linear heuristic iteratively assigns portions of the power flexibility to the most appropriate energy management system for one time slot after another, minimizing the total flexibility cost or maximizing the probability of flexibility delivery. In addition, a multi-objective genetic algorithm is proposed that also takes into account power grid aspects, quality of service, and fairness among par-ticipating households. The genetic operators are tailored to the flexibility disaggregation search space, taking into account flexibility and energy management system constraints, and enable power-optimized buffering of fitness values. Both smart grid applications are validated on a realistic power distribution grid with real driving patterns and energy profiles for photovoltaic generation and household consumption. The results of all proposed algorithms are analyzed with respect to a set of newly defined metrics on quality of service, fairness, efficiency, and utilization of the power distribution grid. One of the main findings is that none of the tested algorithms outperforms the others in all quality of service metrics, however, integration of user expectations improves the service quality compared to simpler approaches. Furthermore, smart grid control that incorporates users and their flexibility allows the integration of high-load applications such as electric vehicle charging and flexibility aggregation from distributed energy storage systems into the existing electricity distribution infrastructure. However, there is a trade-off between power grid aspects, e. g., grid losses and voltage values, and the quality of service provided. Whenever active user interaction is required, means of controlling the quality of service of users' smart grid applications are necessary to ensure user satisfaction with the services provided.}, language = {en} } @phdthesis{Scherling2023, author = {Scherling, Arno}, title = {Der Maler Friedrich D{\"u}rck (1809 - 1884) : Biographie, Rezeption, Malweise, Kritisches Verzeichnis der Werke}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-12383}, school = {Universit{\"a}t Passau}, pages = {461 Seiten}, year = {2023}, abstract = {Diese Monographie schildert die Lebensgeschichte des Malers Friedrich D{\"u}rck (1809 Leipzig - 1884 M{\"u}nchen) von seiner famili{\"a}ren Herkunft {\"u}ber seine k{\"u}nstlerische Ausbildung, sein famili{\"a}res und soziales Leben bis zu seinem Tod.

Over the period December 2017 - March 2019, we find significant time variation in the contribution to price discovery of the two markets. Increases in price discovery are mainly driven by relative trading costs and volume, and by uncertainty to a lesser extent. Additionally, medium-sized trades contain most information in terms of price discovery. Finally, higher news-based bitcoin sentiment increases the informational role of the futures market, while attention and macroeconomic news have no impact on price discovery. Abstract 2: We investigate whether local religious norms affect stock liquidity for U.S. listed companies. Over the period 1997-2020, we find that firms located in more religious areas have higher liquidity, as reflected by lower bid-ask spreads. This result persists after the inclusion of additional controls, such as governance metrics, and further sensitivity and endogeneity analyses. Subsample tests indicate that the impact of religiosity on stock liquidity is particularly evident for firms operating in a poor information environment. We further show that firms located in more religious areas have lower price impact of trades and smaller probability of information-based trading. Overall, our findings are consistent with the notion that religiosity, with its antimanipulative ethos, probably fosters trust in corporate actions and information flows, especially when little is known about the firm. Finally, we conjecture an indirect firm value implication of religiosity through the channel of stock liquidity. Abstract 3: This study shows that higher physical distance to institutional shareholders is associated with higher stock price crash risk. Since monitoring costs increase with distance, the results are consistent with the monitoring theory of local institutional investors. Cross-sectional analyses show that the effect of proximity on crash risk is more pronounced for firms with weak internal governance structures. The significant relation between distance and crash risk still holds under the implementation of the Sarbanes-Oxley Act, however, to a lower extent. Also, the existence of the channel of bad news hoarding is confirmed.
