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. In contrast, the evidence about the effect of methods expertise is more ambivalent.}, language = {en} } @phdthesis{Garbas2022, author = {Garbas, Janina}, title = {From now to next - Three essays on consumer responses to innovative technology-driven business models}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-11132}, school = {Universit{\"a}t Passau}, pages = {XVIII, 212 Seiten}, year = {2022}, abstract = {Over the last decades, ongoing advancements in information technology (i.e., Internet and mobile devices) have expanded a firm's ability to communicate and interact with consumers and hence, create the potential of building sustainable relationships. Tailoring offerings through (1) consumer-initiated customization and (2) firm-initiated personalization is considered a key driver of long-term consumer relationships. As technologies continue to evolve, the opportunities for tailored marketing expand and enable new technology-driven business models that help to leverage customization and personalization and strengthen customer relationships in the era of the digital economy. Across three independent essays, the purpose of this dissertation is to answer the overarching research question of how innovative technology-driven business models versus traditional business models in the domains of customization and personalization influence consumer behavior. Thereby, this dissertation contributes to an understanding of challenges and opportunities of innovative customization and personalization business models with the ultimate goal of enabling their successful diffusion in the marketplace. Specifically, in Essay 1 and Essay 2, I investigate an innovative business model located in the realm of customization, that is, internal product upgrades (i.e., offering fee-based access to originally built-in, but deliberately restricted, optional features). Using a conceptual approach, Essay 1 provides a framework for understanding how internal product upgrades will likely influence consumers' responses. As such, it outlines evolving challenges and opportunities of internal product upgrades and derives questions for future research. In Essay 2, I use an empirical approach to examine pitfalls of internal product upgrades in the product usage phase. Drawing on research on normative expectations and perceived ownership, this essay reveals that consumers respond less favorably to internal (vs. external) product upgrades and investigates managerially relevant boundary conditions. Finally, Essay 3 creates novel insights into a business model in the domain of personalization. This essay examines how the increasingly prevalent data disclosure practice of firms engaging in a network with other firms to exchange consumer data, which we denote as Business Network Data Exchange (BNDE), influences consumers' privacy-related decision-making. In particular, this essay shows that consumers are less likely to disclose personal data in BNDE (vs. traditional dyadic) data exchange settings and that immediate affective reactions are crucial in explaining consumers' privacy-related decision-making. Within this dissertation, I make substantial contributions at a more general level to literature on customization and personalization by comparing innovative business models to established ones. At the individual essay level, I extend existing research in the domains of product feature modifications, norm violations, and privacy-related decision making. Moreover, this dissertation provides actionable implications for managers who are facing the decision to transform their established business model into an innovative technology-driven one.}, language = {en} } @phdthesis{Resch2022, author = {Resch, Ren{\´e} Matthias}, title = {Three Essays on Brand Management in the Business-to-Business Context: Brand Identity, Brand Culture, and Brand Essence}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-11589}, school = {Universit{\"a}t Passau}, pages = {XVI, 187 Seiten}, year = {2022}, abstract = {This dissertation examines the overarching research question of how the suppliers' brand management in the form of brand identity, brand culture, and brand essence influences buyer-seller relationships in three independent essays. In Essay 1, I address the structure, capabilities, and outcomes of brand identity from a supplier perspective. Through qualitative interviews with suppliers, I examine how widespread the concept of brand identity is in practice and what exactly practitioners understand by it. Going further, I look at what capabilities and conditions are necessary for brand identity to be successful and what outcomes suppliers hope to achieve. Using an Information-Display-Matrix (IDM) test and a sample of Master of Business Administration (MBA) students, I examine the relevance of brand functions in more detail. In Essay 2, I use a dyadic dataset with matched buyer-seller dyads to examine the causes and effects of perceptual congruence and incongruence of brand culture strength on the buyer-seller relationship, while considering relationship-specific investments and interaction mechanisms as moderating effects. I show that congruence and incongruence have different effects on customer loyalty and price sensitivity and that these are strongly context-dependent. In Essay 3, I deal with brand essence strength interactions and their effects on the buyer-seller relationship. I use a dyadic dataset with matched buyer-seller dyads to show how brand essence strength influences customer loyalty and customer profitability, and how it interacts with key customer attitudes and other important buyer-seller relationship closeness indicators. This dissertation makes a significant contribution to the literature on brand identity, brand culture, and brand essence in buyer-seller relationships.

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.

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

Political elites, architects, and designers, as well as ordinary citizens co-constructed and explored the rising spheres through the languages of their respective fields—by producing regulations and laws, designing and erecting new types of buildings, developing new and modernizing already familiar everyday objects as well as devising new ways of integrating these objects into private and public spaces. Alongside these voices, transformations in the cultural sphere in general, and literature in particular, were most vocal. The late Soviet era witnessed the dissolution of the ossified ideology of socialist realism that focused on the glorification of the "new Soviet man" and had held culture in its tight grips since the 1930s. Starting from the 1950s, writers increasingly focused on portraying areas of life that lay beyond one's public commitments and experimented with new meanings, codes, and forms to give shape to novel spheres of experience of the "late Soviet man" that can be subsumed under the concept of the "private sphere." The analytical framework of my dissertation is built around the journey to understand the mechanisms and architecture that powered the imagination of models of distancing oneself from the state and the society at large—scenarios of privacy, as we may call them today. I examine Russian prose and drama of the 1950s-1980s as a laboratory for the ideas of privacy, which was increasingly sought in the society disillusioned by the Communist doctrine and thus progressively alienating from active participation in the public sphere. I analyze the meanings that writers incorporated into new and old forms of domesticity—private flats that became progressively widespread throughout the 1950s-1980s, rooms in communal apartments, individual houses—to determine the spectrum of concepts that nurtured the idea of privacy in the late Soviet literary imagination. I also examine representations of reciprocal paradigms of relations between subjects from which the state and society at large were increasingly excluded. In the examples that I analyze, forms of private withdrawals variate from establishing control over liminal spaces or escaping into the world of feelings and emotions and building a connection to a person or space (significant for the characters for private rather than public reasons) to experimenting with language and pursuing one's idiolect despite the ubiquitous "officialese," as well as living in temporalities asynchronous with the public time. Beyond revealing the visions of different, non-state existences in the late Soviet era, my text also advocates examining the role of official literature as a platform for subversion and change that was no less important in an authoritarian state than dissident literature. I see officially published texts as a cultural subaltern who defies the state of affairs and slowly but firmly turns the "state sphere" into a public one by pushing its own agenda through publications that test and gain ground for bolder visions of Soviet life that are not predicated on the commitment to the public sphere. With individual mechanisms of power assertion employed by the state or literature in the late Soviet era well-researched, the framework is still missing that would capture the shifts of borders between the private and public spheres under the influence of these actors. In devising such framework, I build upon sociological theories of disattendability and civil inattention that Erving Goffman conceived to describe conventions of individual behavior and social interaction in public. Extending these theories toward the studies of literary politics, I argue that by envisioning scenarios of a private retreat and bringing them into officially published editions, literature normalized privacy as a late Soviet imaginary and, therefore, continuously heightened its own disattendability, thereby expanding the borders of the private sphere. On the side of the state, the border was defined by the triggers of disturbance of civil inattention: privacy was conceded in return for disattendability. Under such conditions, literature became a bizarre "private kitchen" that performed private and public functions simultaneously—similar to the kitchens in newly-built individual apartments that were popular loci of socialization in the late Soviet era. It turned into a place where one can escape—it became one of the "niches of privacy" where it was possible to discuss and negotiate the world, in which the society lived or to which it should strive. At the same time, it assumed the role of a surrogate for the public sphere within the "state" sphere by pushing its own agenda through the publication of literary texts that sought to imagine a person rather than a cog in the Communist machine and thus transformed socialist realism into a literary current "with a human face." In my research, privacy, literature, and politics are bound together to reveal a vibrant spectacle of the continuous interaction between the state, cultural elites, and the citizens, in which thresholds are erected and crossed incessantly. Fictional private sites were battlefields for the production and contestation of ideologies, and the exposure of these literary wars to the public eye played a fundamental role in shifting the borders between the private and the public spheres in an authoritarian late Soviet Russia. The patterns of relations between the state and culture that I uncover in my dissertation resonate in neo-authoritarian twenty-first-century Russia, making privacy an important lens for our insight into the role of culture in rising authoritarian and failing democratic systems across the globe.}, language = {en} } @phdthesis{Mussotter2023, author = {Mußotter, Marlene}, title = {On nation, homeland, and democracy: Toward a novel three-factor measurement model for nationalism and patriotism}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-13781}, school = {Universit{\"a}t Passau}, pages = {100, ca. 100 ungez{\"a}hlte Seiten}, year = {2023}, abstract = {The nationalism-patriotism distinction is one of the most influential distinctions in the field of political psychology.

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.

IT-Exposure and Firm Value: We analyze the joint influence of a firm's information technology (IT)-Exposure and investment behavior on firm value. Estimating a firm's (partial) IT-Exposure allows for distinguishing between firms with a business model that is challenged by IT above and below market average. Hence, we estimate the annual IT-Exposure of a firm using a 3-factor Fama-French model extended by an IT-proxy. Subsequently, we analyze the relationship with Tobin's Q in a panel data context, accounting for the relationship between IT-Exposure and investments proxied by R\&D as well as CapEx. We use more than 48,000 firm-year observations for firms in the Russell 3000 Index covering the period 1990 to 2018. Although IT-Exposure has a negative impact on firm value, this discount can be overcompensated by up to 2.1 times by sufficient investments through R\&D and CapEx, giving a firm with an average Tobin's Q a premium of 14.8\% to 19.2\%, while controlling for endogeneity. 2. Corporate Social Responsibility, Risk, and Firm Value: An Unconditional Quantile Regression Approach: This paper examines the impact of corporate social responsibility (CSR) on firm risk, comprising total risk, idiosyncratic risk, and systematic risk, as well as firm value. We focus on analyzing the interrelationships along the entire distribution of the dependent variables, thus estimating an unconditional quantile regression (UQR). The analysis is based on CSR scores from Refinitiv and MSCI, using up to 12,013 firm-year observations over the period 2002 to 2019 for all U.S. companies listed on NYSE, NASDAQ, and AMEX. UQR reveals strongly heterogeneous effects along the unconditional quantiles of the dependent variables, which are reflected in sign changes, magnitude and significance variations. For CSR we find a risk-reducing as well as value-enhancing effect. When applying fixed effects OLS, we can just partly confirm the risk-reducing and value-enhancing effect of CSR shown in the literature. 3. Heterogenous Effects of Religiosity on Firm Risk and Firm Value: An Unconditional Quantile Regression Approach: This paper examines the impact of religiosity on firm risk, comprising total risk, idiosyncratic risk, and systematic risk, as well as firm value.

UQR reveals strongly heterogeneous effects along the unconditional quantiles of the dependent variables, which are reflected in sign changes, magnitude and significance variations. Overall, the risk-reducing effect of religiosity is more pronounced in the higher quantiles of the distribution. We further observe a value-reducing as well as value-enhancing religiosity effect.

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.

Arguably, religion shapes or even constitutes the international society of states, an aspect so far neglected in the field of International Relations. The dissertation provides a new definition of religion for International Relations and the English School in particular. Based upon this understanding of religion, the five publications presented in the dissertation provide new analytical and theoretical concepts and approaches to fill the research gap. Religion is integrated into the theoretical framework of the English School in the form of a "prime institution" and with the help of the "quilt model". While the former expands the theoretical framework, the latter adds an analytical layer. Based upon this definition religion is also introduced as a concept ("hybrid actorness") in Foreign Policy Analysis, opening it up to become less state-centrist and more transnational-oriented, thereby boosting its relevance considering the evolving international (global) society. In another step, the Securitization framework of analysis is expanded to include (freedom) of religion.

Our proposed method outperforms the existing approach in voltage prediction. Subsequently, we enhance the proposed approach by incorporating a second deep RL algorithm—dueling DQN—which is an improvement of DQN, resulting in a 10\% improvement in the results, especially in terms of voltage prediction.

In order to alleviate the range of anxiety of users, we perform a Deep Reinforcement Learning (DRL) approach that provides the optimal charging time slots for EV based on the Photovoltaic power prices, the current EV SOC, the charging connector type, and the history of load demand profiles collected in different locations. Our implemented approach maximizes the EV profit while giving a margin of liberty to the EV drivers to select the preferred CS and the best charging time (i.e., morning, afternoon, evening, or night).

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.

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} } @phdthesis{Mladenov2024, author = {Mladenov, Mladen}, title = {Running in the Hamster Wheel.

This research presents a case study on coastal flooding and its impact on livelihoods in the Volta Region of Ghana. The paper utilizes a vulnerability framework that focuses on exposure, susceptibility, as well as the capacities to anticipate, cope with, and recover from the effects of natural hazards. Based on a qualitative approach, the study focusses on those households who were directly affected of a severe tidal flood in November 2021, leading to a total destruction of their property. The research was conducted in March, July and August 2022. It revealed that the studied group had low capacity to anticipate and had no contingency plans in case of relocation. Further, we discovered different strategies that people applied to deal with the situation eight months after the flood event. Most households applied (short term) coping strategies to reestablish their former marine-based livelihood systems.

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} } @book{Bleyer2009, author = {Bleyer, Bernhard}, title = {Subjektwerdung des Armen.

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.

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{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.

Die katholischen Synoden im fr{\"u}hneuzeitlichen Polen-Litauen bildeten hiervon keine Ausnahme: Obwohl Versammlungen des Klerus, waren sie stark ins politische System eingebunden, das sich zu einer Wahlmonarchie mit starkem Adel und parlamentarischen Elementen entwickelte. Diese Arbeit untersucht systematisch die politischen Aspekte der Provinzial- und Primatialsynoden in Polen-Litauen von 1447 bis 1643 aus der Perspektive der Kulturgeschichte des Politischen.

First, they are confronted with surging rates of non-communicable diseases (NCDs), and second, climate change will take its toll and is predicted to cause catastrophic health impairments and exacerbate chronic health conditions further. Both will pose a disproportionate health and economic burden on low- and middle-income countries, which are also the countries least able to cope with them. By threatening individual health and socioeconomic improvements, and by putting an immense burden on already constrained health care systems, they impede the progress in poverty reduction and widen health inequities between the rich and the poor.

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

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.

For media companies, promoting journalism literacy seems logical for economic and altruistic reasons. However, research on German initiatives is scarce. This article presents an explorative qualitative survey of experts from seven media companies offering journalistic media education projects in German schools, focusing on the initiatives' content, structure, and motivation. Results show that initiatives primarily aim at students and teachers, offering mostly education on journalism (e.g., teaching material) and via journalism (e.g., journalistic co-production with students). While these projects mainly provide information on the respective medium and journalistic practices, dealing with disinformation is also a central goal. Most initiatives are motivated both extrinsically (e.g., reaching new audiences) and intrinsically (e.g., democratic responsibility). Despite sometimes insufficient resources and reluctant teachers, media companies see many opportunities in their initiatives: Gaining trust and creating resilience against disinformation are just two examples within the larger goal of enabling young people to be informed and opinionated members of a democratic society.}, language = {en} } @techreport{Klumpp2023, author = {Klumpp, Lorenz}, title = {Populism by the media: Bildtypen in der Darstellung des politischen Personals auf Compact-Covern - eine Forschungsdokumentation}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-12458}, year = {2023}, abstract = {Die vorliegende Forschungsdokumentation stellt die in einer Studie ermittelten Bildtypen auf Covern des Compact-Magazins detailliert mittels der ikonographisch-ikonologischen Analyse vor.

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{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.

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{Sentanoe2024, author = {Sentanoe, Stewart}, title = {VMIaaS: Virtual Machine Introspection as a Service}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-15027}, school = {Universit{\"a}t Passau}, pages = {vi, 121 Seiten}, year = {2024}, abstract = {In this digital era, communication in the digital world is becoming part of our daily lives. 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{Ghaffar2024, author = {Ghaffar, Abdul Muqeet}, title = {Understanding Individuals' Willingness for Prosocial Data Disclosure: Exploring Antecedents and Investigating Strategies for its Promotion}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-15001}, school = {Universit{\"a}t Passau}, pages = {iv, 94 Seiten}, year = {2024}, abstract = {Privacy research has traditionally focused on understanding individuals' behavior in disclosing personal data by assuming that individuals disclose their data mainly out of self-interest.

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.

The SCRATCH programming environment is particularly popular, with more than 90 million registered users at the time of this writing. While the block-based nature of S CRATCH helps learners by preventing syntactical mistakes, there nevertheless remains a need to provide feedback and support in order to implement desired functionality. To support individual learning and classroom settings, this feedback and support should ideally be provided in an automated fashion, which requires tests to enable dynamic program analysis. In prior work we introduced W HISKER , a framework that enables automated testing of S CRATCH programs. However, creating these automated tests for S CRATCH programs is challenging. In this paper, we therefore investigate how to automatically generate W HISKER tests. Generating tests for S CRATCH raises important challenges: First, game-like programs are typically randomised, leading to flaky tests. Second, S CRATCH programs usually consist of animations and interactions with long delays, inhibiting the application of classical test generation approaches. Thus, the new application domain raises the question of which test generation technique is best suited to produce high coverage tests capable of detecting faulty behaviour. We investigate these questions using an extension of the W HISKER test framework for automated test generation. Evaluation on common programming exercises, a random sample of 1000 S CRATCH user programs, and the 1000 most popular S CRATCH programs demonstrates that our approach enables W HISKER to reliably accelerate test executions, and even though many SCRATCH programs are small and easy to cover, there are many unique challenges for which advanced search-based test generation using many-objective algorithms is needed in order to achieve high coverage.}, language = {en} } @article{Narh2023, author = {Narh, John}, title = {The resource curse and the role of institutions revisited}, series = {Environment, Development and Sustainability}, volume = {27}, journal = {Environment, Development and Sustainability}, publisher = {Springer Nature}, address = {Berlin}, doi = {10.1007/s10668-023-04279-6}, url = {http://nbn-resolving.de/urn:nbn:de:101:1-2024030609203689018522}, pages = {8187 -- 8207}, year = {2023}, abstract = {Many studies have shown that natural resource abundant countries with strong institutions tend to escape the resource curse.

In this review, I argue that managing and distributing natural resource wealth through a centralised planning strategy and lack of a binding long-term national development plan are institutional conditions that encourage government unaccountability as they do not restrict policy makers against discretionary distribution of natural resource windfall, rent seeking, clientelism and corruption which contribute to poor economic development and growth.

In contrast, there has been only limited dialogue between theoretical and empirical approaches to the NPD. The article illustrates how research drawing on the NPD could profit from the CED's evolution.

In this article, we ask whether ASATs have a measurable impact on external software quality, using the example of PMD for Java. We investigate the relationship between ASAT warnings emitted by PMD on defects per change and per file. Our case study includes data for the history of each file as well as the differences between changed files and the project in which they are contained. We investigate whether files that induce a defect have more static analysis warnings than the rest of the project. Moreover, we investigate the impact of two different sets of ASAT rules. We find that, bug inducing files contain less static analysis warnings than other files of the project at that point in time. However, this can be explained by the overall decreasing warning density. When compared with all other changes, we find a statistically significant difference in one metric for all rules and two metrics for a subset of rules. However, the effect size is negligible in all cases, showing that the actual difference in warning density between bug inducing changes and other changes is small at best.}, language = {en} } @article{FruehwirthProchno2023, author = {Fr{\"u}hwirth, Lorenz and Prochno, Joscha}, title = {H{\"o}lder's inequality and its reverse — a probabilistic point of view}, series = {Mathematische Nachrichten}, volume = {296}, journal = {Mathematische Nachrichten}, number = {12}, publisher = {Wiley}, address = {Hoboken}, doi = {10.1002/mana.202200411}, url = {http://nbn-resolving.de/urn:nbn:de:101:1-2023062315175042989607}, pages = {5493 -- 5512}, year = {2023}, abstract = {In this article, we take a probabilistic look at H{\"o}lder's inequality, considering the ratio of terms in the classical H{\"o}lder inequality for random vectors in ℝ𝑛.

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.

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{Welearegai2023, author = {Welearegai, Gebrehiwet Biyane}, title = {Precise Detection of Injection Attacks in Real-world Applications}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-12926}, school = {Universit{\"a}t Passau}, pages = {xvi, 120 Seiten}, year = {2023}, abstract = {Code injection attacks like the one used in the high-profile 2017 Equifax breach, have become increasingly common, ranking at the top of OWASP's list of critical web application vulnerabilities. The injection attacks can also target embedded applications running on processors like ARM and Xtensa by exploiting memory bugs and maliciously altering the program's behavior or even taking full control over a system. Especially, ARM's support of low power consumption without sacrificing performance is leading the industry to shift towards ARM processors, which advances the attention of injection attacks as well. In this thesis, we are considering web applications and embedded applications (running on ARM and Xtensa processors) as the target of injection attacks. To detect injection attacks in web applications, taint analysis is mostly proposed but the precision, scalability, and runtime overhead of the detection depend on the analysis types (e.g., static vs dynamic, sound vs unsound). Moreover, in the existing dynamic taint tracking approach for Java- based applications, even the most performant can impose a slowdown of at least 10-20\% and often far more. On the other hand, considering the embedded applications, while some initial research has tried to detect injection attacks (i.e., ROP and JOP) on ARM, they suffer from high performance or storage overhead. Besides, the Xtensa has been neglected though used in most firmware-based embedded WiFi home automation devices. This thesis aims to provide novel approaches to precisely detect injection attacks on both the web and embedded applications. To that end, we evaluate JavaScript static analysis frameworks to evaluate the security of a hybrid app (JS \& native) from an industrial partner, provide RIVULET - a tool that precisely detects injection attacks in Java-based real-world applications, and investigate injection attacks detection on ARM and Xtensa platforms using hardware performance counters (HPCs) and machine learning (ML) techniques. To evaluate the security of the hybrid application, we initially compare the precision, scalability, and code coverage of two widely-used static analysis frameworks—WALA and SAFE. The result of our comparison shows that SAFE provides higher precision and better code coverage at the cost of somewhat lower scalability. Based on these results, we analyze the data flows of the hybrid app via taint analysis by extending the SAFE's taint analysis and detected a potential for injection attacks of the hybrid application. Similarly, to detect injection attacks in Java-based applications, we provide Rivulet which monitors the execution of developer-written functional tests using dynamic taint tracking. Rivulet uses a white-box test generation technique to re-purpose those functional tests to check if any vulnerable flow could be exploited. We compared Rivulet to the state-of-the-art static vulnerability detector Julia on benchmarks and Rivulet outperformed Julia in both false positives and false negatives. We also used Rivulet to detect new vulnerabilities. Moreover, for applications running on ARM and Xtensa platforms, we investigate ROP1 attack detection by combining HPCs and ML techniques. We collect data exploiting real- world vulnerable applications and small benchmarks to train the ML. For ROP attack detection on ARM, we also implement an online monitor which labels a program's execution as benign or under attack and stops its execution once the latter is detected. Evaluating our ROP attack detection approach on ARM provides a detection accuracy of 92\% for the offline training and 75\% for the online monitoring. Similarly, our ROP attack detection on the firmware-only Xtensa processor provides an overall average detection accuracy of 79\%. Last but not least, this thesis shows how relevant taint analysis is to precisely detect injection attacks on web applications and the power of HPC combined with machine learning in the control flow injection attacks detection on ARM and Xtensa platforms.}, language = {en} } @phdthesis{Dietrich2025, author = {Dietrich, Philip}, title = {Moralische Entscheidung in virtuellen Handlungswelten.

Als generationen{\"u}bergreifendes und interaktives Medium er{\"o}ffnen digitale Spiele durch die Verkn{\"u}pfung von Narration und Interaktion die M{\"o}glichkeit, alternative Perspektiven einzunehmen und neue Rollen zu erproben. Auf Basis von vier Teilstudien wird der Frage nachgegangen, wie gesellschaftlich bedeutsame Inhalte in digitalen Spielen verantwortungsvoll gestaltet und vermittelt werden k{\"o}nnen. Die erste Teilstudie identifiziert zentrale Nutzungsmotive und weist Spielende als potenzielle moralische Handlungstr{\"a}ger (Moral Agents) aus. Sie zeigt auf, dass moralische Dilemmata, die innerhalb virtueller Spielwelten erfahren werden, Relevanz f{\"u}r moralische Urteilsbildungsprozesse in der realen Welt entfalten k{\"o}nnen. Die zweite Teilstudie kn{\"u}pft an diese Erkenntnisse an und untersucht anhand von Expert:inneninterviews das Potenzial digitaler Spiele f{\"u}r eine digitale Erinnerungskultur. Die dritte Teilstudie entwickelt ein Modell f{\"u}r die gelingende Vermittlung gesellschaftlich relevanter Themen im digitalen Spiel. Hierbei wird insbesondere die integrative Funktion von Narration und Interaktion als zentrales Gestaltungsprinzip herausgestellt. Die vierte Teilstudie erweitert dieses Modell um die Dimension der {\"A}sthetik, die als konstitutives Element der Wirklichkeitswahrnehmung und Sinnkonstitution innerhalb virtueller Spielr{\"a}ume fungiert. Die Ergebnisse verdeutlichen, dass f{\"u}r eine verantwortungsvolle Vermittlung gesellschaftlich relevanter Inhalte im digitalen Spiel eine digitale Moral Agency erforderlich ist. Diese bef{\"a}higt Spielende dazu, moralisch zu handeln und das eigene Handeln kritisch zu reflektieren. Die Verbindung von Narration und Interaktion erweist sich dabei als zentrales Mittel zur Initiierung von Perspektivwechseln, zur {\"U}bernahme fremder Rollen und zur F{\"o}rderung reflexiver Prozesse. {\"A}sthetisierungsprozesse innerhalb der Spielwelten tragen wesentlich dazu bei, diese kognitiven und affektiven Auseinandersetzungen anzustoßen und zu vertiefen.}, subject = {Spielwissenschaft}, language = {de} } @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, this approach has limitations, primarily that of being dependenton expensive human expert knowledge. There have been attempts to replace manual aggre-gation through automatic feature extraction approaches. They, however, do not consider thespecific structure of the manual aggregates. 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. Furthermore, the NAG extends learnable aggregates over traditionalones through soft feature value matching and relative weighting of the importance of differ-ent feature constraints. 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. Unlike the LSTMor the CNN, our approach also provides further interpretability through the inspection of itsparameters.}, language = {en} } @phdthesis{Luick2025, author = {Luick, Karen}, title = {Reisebegegnungen in Marokko}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:739-opus4-16024}, school = {Universit{\"a}t Passau}, pages = {v, 371 Seiten}, year = {2025}, abstract = {Die Arbeit beleuchtet Marokko als Reiseziel f{\"u}r Individualreisende aus landeskundlicher und tourismusgeographischer Perspektive.
