Aspects of visual avatar appearance: self-representation, display type, and uncanny valley
(2021) Hepperle, Daniel; Purps, Christian Felix; Deuchler, Jonas; Wölfel, Matthias
The visual representation of human-like entities in virtual worlds is becoming a very important aspect as virtual reality becomes more and more “social”. The visual representation of a character’s resemblance to a real person and the emotional response to it, as well as the expectations raised, have been a topic of discussion for several decades and have been debated by scientists from different disciplines. But as with any new technology, the findings may need to be reevaluated and adapted to new modalities. In this context, we make two contributions which may have implications for how avatars should be represented in social virtual reality applications. First, we determine how default and customized characters of current social virtual reality platforms appear in terms of human likeness, eeriness, and likability, and whether there is a clear resemblance to a given person. It can be concluded that the investigated platforms vary strongly in their representation of avatars. Common to all is that a clear resemblance does not exist. Second, we show that the uncanny valley effect is also present in head-mounted displays, but - compared to 2D monitors - even more pronounced.
Between trust and ambivalence: how does trainee teachers’ perception of the relationship with their mentors explain how trainee teachers experience their work?
(2024) Maué, Elisabeth; Goller, Michael; Bonnes, Caroline; Kärner, Tobias
The study aims to identify profiles of trainee teachers in terms of their stress and work experiences and to uncover profile differences in regard to dropout intentions and perceived relationships between trainee teachers and their mentors. Based on data from 1,756 German trainee teachers, three distinct stress and work experience profiles could be identified. Trainee teachers with high levels of stress and negative work experiences exhibit higher dropout intentions and experience their relationship with their mentors as less transparent, fair and trusting, and more ambivalent compared to trainee teachers with low levels of stress and positive work experiences. The results underline the importance of the relationship between mentors and trainee teachers for the professional development of future teachers.
Emotions and entrepreneurial finance: analysis of venture capitalists’ and business angels’ digital footprints on Twitter
(2024) Kaiser, Manuel; Kuckertz, Andreas
Emotions are a central concept in previous entrepreneurship research, but this is mainly related to entrepreneurs and their entrepreneurial journey. However, venture capitalists (VCs) and business angels (BAs), two critical investors in the entrepreneurial finance literature, are essential actors in the entrepreneurial process. Still, little is known about investor emotions in this context. Therefore, in this study, we ask how venture capitalists differ from business angels in terms of their expressed emotions. To this end, we use an increasingly familiar research approach by examining the digital footprints of these investors on Twitter. For this purpose, we identify 822 investors from Crunchbase and analyze their 994,969 Tweets with Linguistic Inquiry and Word Count (LIWC) as a text analysis tool. Our results show that venture capitalists display more positive emotions on Twitter than angel investors, meaning that we find an association between VCs and emotional tone. Furthermore, in our post-hoc analysis, we explore further explanations for the differences between VC and BA. In doing so, we show differences in their expressed cognitive processes as well as in their communicated drivers. In both concepts, we find positive associations with the investor type of VC. To conclude this paper, we develop implications for practice and further research based on the results.
A generalized representation of Faà Di Bruno'S formula using multivariate and matrix‐valued Bell polynomials
(2025) Evers, Michael P.; Kontny, Markus
We provide a generalization of Faà di Bruno’s formula to represent the 𝑛-th total derivative of the multivariate and vector-valued composite 𝑓 ∘𝑔. To this end, we make use of properties of the Kronecker product and the 𝑛-th derivative of the left-composite 𝑓 , which allow the use of a multivariate and matrix-valued form of partial Bell polynomials to represent the generalized Faà di Bruno’s formula. We further show that standard recurrence relations that hold for the univariate partial Bell polynomial also hold for the multivariate partial Bell polynomial under a simple transformation. We apply this generalization of Faà di Bruno’s formula to the computation of multivariate moments of the normal distribution.
Guidelines for using financial incentives in software-engineering experimentation
(2024) Krüger, Jacob; Çalıklı, Gül; Bershadskyy, Dmitri; Otto, Siegmar; Zabel, Sarah; Heyer, Robert
Context: Empirical studies with human participants (e.g., controlled experiments) are established methods in Software Engineering (SE) research to understand developers’ activities or the pros and cons of a technique, tool, or practice. Various guidelines and recommendations on designing and conducting different types of empirical studies in SE exist. However, the use of financial incentives (i.e., paying participants to compensate for their effort and improve the validity of a study) is rarely mentioned Objective: In this article, we analyze and discuss the use of financial incentives for human-oriented SE experimentation to derive corresponding guidelines and recommendations for researchers. Specifically, we propose how to extend the current state-of-the-art and provide a better understanding of when and how to incentivize. Method: We captured the state-of-the-art in SE by performing a Systematic Literature Review (SLR) involving 105 publications from six conferences and five journals published in 2020 and 2021. Then, we conducted an interdisciplinary analysis based on guidelines from experimental economics and behavioral psychology, two disciplines that research and use financial incentives. Results: Our results show that financial incentives are sparsely used in SE experimentation, mostly as completion fees. Especially performance-based and task-related financial incentives (i.e., payoff functions) are not used, even though we identified studies for which the validity may benefit from tailored payoff functions. To tackle this issue, we contribute an overview of how experiments in SE may benefit from financial incentivisation, a guideline for deciding on their use, and 11 recommendations on how to design them. Conclusions: We hope that our contributions get incorporated into standards (e.g., the ACM SIGSOFT Empirical Standards), helping researchers understand whether the use of financial incentives is useful for their experiments and how to define a suitable incentivisation strategy.
How news audiences allocate trust in the digital age: A figuration perspective
(2024) Mangold, Frank; Bachl, Marko; Prochazka, Fabian
The article enriches the understanding of trust in news at a time when mass and interpersonal communication have merged in the digital sphere. We propose disentangling individual-level patterns of trust allocation (i.e., trust figurations ) across journalistic media, social media, and peers to reflect the multiplicity among modern news audiences. A latent class analysis of a representative survey among German young adults revealed four figurations: traditionalists, indifferentials, optimists, and cynics. Political characteristics and education corresponded with substantial heterogeneity in individuals’ trust in news sources, their inclination to differentiate between sources, and the ways of integrating trust in journalistic and non-journalistic sources.
A longitudinal analysis of the privacy paradox
(2021) Dienlin, Tobias; Masur, Philipp K; Trepte, Sabine
The privacy paradox states that people’s concerns about online privacy are unrelated to their online sharing of personal information. On the basis of a representative sample of the German population, which includes 1,403 respondents interviewed at three waves separated by 6 months, we investigate the privacy paradox from a longitudinal perspective. Using a cross-lagged panel model with random intercepts, we differentiate between-person relations from within-person effects. Results revealed that people who were more concerned about their online privacy than others also shared slightly less personal information and had substantially more negative attitudes toward information sharing (between-person level). People who were more concerned than usual also shared slightly less information than usual (within-person level). We found no long-term effects of privacy concerns on information sharing or attitudes 6 months later. The results provide further evidence against the privacy paradox, but more research is needed to better understand potential causal relations.
Metropolitan, urban, and rural regions: how regional differences affect elementary school students in Germany
(2025) Schwerter, Jakob; Bleher, Johannes; Doebler, Philipp; McElvany, Nele
This study examined how regional differences affect elementary school students using the representative German Progress in International Reading Literacy Study (PIRLS) 2016 data (N = 3,959 fourth-grade students; M_{Age} = 10.34 years; 49% girls; 71% from a nonimmigrant background) by combining bootstrapping, multiple imputations, principal component analysis, and the least absolute shrinkage and selection operator (LASSO). Grouping regions into rural, (sub-)urban, and metropolitan, we found that students from rural and metropolitan areas are 10.9% and 15.1% more likely, respectively, to receive an academic track recommendation than their urban counterparts. Similarly, rural and metropolitan students are 0.2 to 0.3 standard deviations more likely to enjoy school and be interested in reading than their urban counterparts. Aside from students’ backgrounds and skills, many of the characteristics explaining this regional difference are structural, directly affected by policy decisions. Variables directly and indirectly influenced by policy help explain regional differences, but nonpolicy variables reduce regional differences in academic track recommendations the most.
Need strength, perceived need support, stress symptomatology, and performance in the context of oral exams: A typological approach
(2022) Schürmann, Linda; Kärner, Tobias; Ringeisen, Tobias
Introduction: Based on self-determination theory, we investigated whether examinees are classifiable into profiles based on basic need strength and perceived need support that differ in stress parameters and achievement in the context of a standardized oral exam. Methods: 92 students reported their basic need strength before and perceived need support provided by the examiner once after the exam. Students indicated their emotions and stress perception at four measurement points and we measured their saliva cortisol concurrently, analyzing stress-related changes over time. Results: Latent class analyses revealed two higher-quality (low/high, high/high) and two lower-quality (low/low, high/low) need strength/need support classes. Physio-affective stress development was typical of exam situations. Higher-quality classes that met or exceeded the needs displayed more beneficial stress and emotion response patterns than lower-quality classes. Gain-related emotions mediated achievement in the higher-quality classes. Discussion: Need-supportive examiners can promote student well-being and achievement when they succeed in providing high need satisfaction.
Palliative care as a digital working world (PALLADiUM) - a mixed-method research protocol
(2023) Grimminger, Sandra; Heckel, Maria; Markgraf, Moritz; Peuten, Sarah; Wöhl, Moritz; Gimpel, Henner; Klein, Carsten; Ostgathe, Christoph; Steigleder, Tobias; Schneider, Werner
Background: In Palliative Care, actors from different professional backgrounds work together and exchange case-specific and expert knowledge and information. Since Palliative Care is traditionally distant from digitalization due to its holistically person-centered approach, there is a lack of suitable concepts enabling digitalization regarding multi-professional team processes. Yet, a digitalised information and collaboration environment geared to the requirements of palliative care and the needs of the members of the multi-professional team might facilitate communication and collaboration processes and improve information and knowledge flows. Taking this chance, the presented three-year project, PALLADiUM, aims to improve the effectiveness of Palliative Care teams by jointly sharing available inter-subjective knowledge and orientation-giving as well as action-guiding practical knowledge. Thus, PALLADiUM will explore the potentials and limitations of digitally supported communication and collaboration solutions. Methods: PALLADiUM follows an open and iterative mixed methods approach. First, ethnographic methods – participant observations, interviews, and focus groups – aim to explore knowledge and information flow in investigating Palliative Care units as well as the requirements and barriers to digitalization. Second, to extend this body, the analysis of the historical hospital data provides quantitative insights. Condensing all findings results in a to-be work system. Adhering to the work systems transformation method, a technical prototype including artificial intelligence components will enhance the collaborative teamwork in the Palliative Care unit. Discussion: PALLADiUM aims to deliver decisive new insights into the preconditions, processes, and success factors of the digitalization of a medical working environment as well as communication and collaboration processes in multi-professional teams.
Response Item Network (ResIN): A network-based approach to explore attitude systems
(2024) Carpentras, Dino; Lueders, Adrian; Quayle, Michael
Belief network analysis (BNA) refers to a class of methods designed to detect and outline structural organizations of complex attitude systems. BNA can be used to analyze attitude-structures of abstract concepts such as ideologies, worldviews, and norm systems that inform how people perceive and navigate the world. The present manuscript presents a formal specification of the Response-Item Network (or ResIN), a new methodological approach that advances BNA in at least two important ways. First, ResIN allows for the detection of attitude asymmetries between different groups, improving the applicability and validity of BNA in research contexts that focus on intergroup differences and/or relationships. Second, ResIN’s networks include a spatial component that is directly connected to item response theory (IRT). This allows for access to latent space information in which each attitude (i.e. each response option across items in a survey) is positioned in relation to the core dimension(s) of group structure, revealing non-linearities and allowing for a more contextual and holistic interpretation of the attitudes network. To validate the effectiveness of ResIN, we develop a mathematical model and apply ResIN to both simulated and real data. Furthermore, we compare these results to existing methods of BNA and IRT. When used to analyze partisan belief-networks in the US-American political context, ResIN was able to reliably distinguish Democrat and Republican attitudes, even in highly asymmetrical attitude systems. These results demonstrate the utility of ResIN as a powerful tool for the analysis of complex attitude systems and contribute to the advancement of BNA.
