In a design-science-oriented manner, a prototype of a feedforward ANN is demonstrated and refined using the new learning method. The results show that the so-called crystallizing backpropagation increases the control possibilities of neural structures and interpretation chances, while learning can be carried out as usual.

This study shows the importance of dealing with ANN in hierarchies through backpropagation and brings in learning methods as novel ways of interacting with ANN. Practitioners will benefit from this interactive process because they can restrict neural learning to specific architectural components of ANN and can focus further development on specific areas of higher cognitive levels without the risk of destroying valuable ANN structures.}, language = {en} } @article{grosseDetersSchoedel2023, author = {große Deters, Fenne and Schoedel, Ramona}, title = {Keep on scrolling?}, series = {Computers in human behavior}, volume = {150}, journal = {Computers in human behavior}, publisher = {Elsevier Science}, address = {Amsterdam}, issn = {0747-5632}, doi = {10.1016/j.chb.2023.107977}, year = {2023}, abstract = {Smartphones are an integral part of daily life for many people worldwide.

They can help to balance the need to maintain normal life and economic activities as much as possible while still avoiding exponentially growing case numbers. However, a majority of citizens need to be willing to install such an app for it to be effective. Hence, knowledge about drivers for app uptake is crucial. Objective: This study aimed to add to our understanding of underlying psychological factors motivating app uptake. More specifically, we investigated the role of concern for one's own health and concern to unknowingly infect others. Methods: A two-wave survey with 346 German-speaking participants from Switzerland and Germany was conducted. We measured the uptake of two decentralized contact tracing apps officially launched by governments (Corona-Warn-App, Germany; SwissCovid, Switzerland), as well as concerns regarding COVID-19 and control variables. Results: Controlling for demographic variables and general attitudes toward the government and the pandemic, logistic regression analysis showed a significant effect of self-focused concerns (odds ratio [OR] 1.64, P=.002). Meanwhile, concern of unknowingly infecting others did not contribute significantly to the prediction of app uptake over and above concern for one's own health (OR 1.01, P=.92). Longitudinal analyses replicated this pattern and showed no support for the possibility that app uptake provokes changes in levels of concern. Testing for a curvilinear relationship, there was no evidence that "too much" concern leads to defensive reactions and reduces app uptake. Conclusions: As one of the first studies to assess the installation of already launched corona tracing apps, this study extends our knowledge of the motivational landscape of app uptake.

This results in new requirements for the modeling, analysis and design of information processing and performance mapping business processes. In the past, procedures were developed under the name of "process-oriented knowledge management" with which the exchange and use of knowledge in business processes could be represented, analyzed and improved.

Design/methodology/approach This study identifies the most likely holistic future scenario by conducting a two-stage Delphi study involving 59 expert panelists. It addresses 33 projections for six thematic sections of the accommodation sharing industry: relevance, different forms of accommodation sharing, users, hosts, platforms, and finally, industry regulation. Findings The results indicate that the number of shared accommodations and users of home-sharing will increase. Moreover, the cost advantage is the predominant driver for users to engage in the accommodation sharing segment, and for the hosts, the generation of an extra income is the primary incentive. Finally, the regulation within this industry is expected to be more effective in the foreseeable future.

Building on the Rubicon model of human behavior formation, I use a threefold approach to analyze the knowledge-sharing process: public employees' motivation to share knowledge, their intention to share, and knowledge sharing behavior as such. The first article maps the knowledge-sharing behavior of public employees. It builds a typology of behavioral patterns and shows that public employees mainly share their knowledge responsively and directly with a knowledge receiver rather than an information medium. The second article elaborates on the construct of knowledge-sharing motivation and develops a scale to measure this kind of work motivation in a selective and domain-specific way. Data from three studies indicate three dimensions of knowledge-sharing motivation, namely appreciation, growth and altruism, and tangible rewards. Based on these dimensions, the third article analyzes whether the satisfaction of public employees' underlying needs can foster ther knowledge-sharing intention. The study indicates that both tested treatments (appreciation by co-workers, benefits in a performance appraisal) positively affect knowledge-sharing intention if it is explicit knowledge that ought to be shared. However, no effects of either treatment can be found if implicit knowledge is shared. Hence, to foster sharing of explicit knowledge, the analyzed motivation-enhancing rewards can be used in public management practice. To enhance implicit knowledge sharing, ability- and opportunity-enhancing management instruments are discussed. All in all, this dissertation integrates a micro-level perspective on human knowledge sharing into a meso-level perspective on organizational knowledge management.

Gerade bei langfristigem Missverh{\"a}ltnis ohne konstruktive L{\"o}sungsstrategie kann dies negative Folgen auf die individuelle Gesundheit nehmen.Mittels Multimethoden-Ansatz wurden Ergebnisse aus verschiedenen Quellen trianguliert und umfassend erfasst. Basis der Datenerhebung bildeten ExpertInnen-Interviews mit Mitarbeitenden und F{\"u}hrungskr{\"a}ften der teilnehmenden Sozial{\"a}mter. Darauf aufbauend fanden teilnehmende Beobachtungen vor Ort und Befragungen von KundInnen und Mitarbeitenden per Kurzfrageb{\"o}gen nach direkten Interaktionen w{\"a}hrend der Sprechzeiten statt. Als letzter Schritt wurde schließlich eine Gesamtbefragung aller Mitarbeitenden der teilnehmenden Sozial{\"a}mter durchgef{\"u}hrt. Aufgrund der Corona-Pandemie erfolgte letztere jedoch verz{\"o}gert. Die erhobenen Daten lassen auf ein heterogenes Stressbild der Mitarbeitenden schließen, wobei deutliche Ausschl{\"a}ge am oberen Ende der Skala zu verzeichnen sind. Ein Teil der Belegschaft ist demnach {\"u}berdurchschnittlich gestresst. Zwar f{\"u}hrt Stress nicht unmittelbar zur Beeintr{\"a}chtigung der Leistungsf{\"a}higkeit. Ein dauerhaft erh{\"o}htes Niveau zieht jedoch gesundheitliche wie psychische Folgen nach sich. Die hohe Stressbelastung l{\"a}sst sich aufgrund der hier durchgef{\"u}hrten Datenerhebung im Wesentlichen auf hohe Arbeitsanforderungen zur{\"u}ckf{\"u}hren, was eine dauerhafte Belastung darstellen k{\"o}nnte. Weitere Stressquellen ergeben sich aus den hohen psychologischen Anforderungen der Arbeit, der eigentlichen Interaktion mit B{\"u}rgerInnen sowie in Teilen einer unzureichenden Attraktivit{\"a}t des Arbeitsplatzes (z.B. durch fehlende Sauberkeit, L{\"a}rmbel{\"a}stigung etc.). Aufgrund dieser Schlussfolgerungen wird daher empfohlen, aktives Gesundheitsmanagement und Sportkurse in den {\"A}mtern auszubauen. Weiterhin sollte die gegenseitige und professionelle Supervision intensiviert werden.

This applies especially to the mature financial services industry and the future perspectives of traditional financial service providers (FSP). Hence, it remains an open question for both research and practice what DT configurations have a positive impact on firm performance. Against this background, the aim of this exploratory study is to examine how DT dimensions are systemically connected to firm performance of incumbent FSP.

We find that the introduction of new sanctions in Iran and Russia significantly lowered firm-level probabilities of serving these sanctioned markets, while the (temporary) lifting of the U.S. sanctions on Cuba and the removal of sanctions against Myanmar had no or only small trade-inducing effects, respectively. Additionally, the impact of sanctions is very heterogeneous along firm dimensions and by case particularities. Firms that depend more on trade finance instruments are more strongly affected, while prior experience in the sanctioned country considerably softens the blow of sanctions, and firms can be partly immune to the sanctions effect if they are specialized in serving "crisis countries".

Through a multi-study approach consisting of exploratory factor analysis, confirmatory factor analysis, and convergent validity, we provide psychometric evidence showing that people can have distinct preferences for each cognitive process when generating ideas. Furthermore, when validating this scale through an experiment, we find that each style becomes more dominant in predicting overall enjoyment, engagement, and creativity based on different underlying structures of a task. Therefore, this paper makes both theoretical and empirical contributions to literature by unpacking intrinsic motivation, showing how the alignment between different creative thinking styles and task can be essential to predicting intrinsic motivation, thus reversing the direction of causality between the motivational and cognitive components of creativity typically assumed in literature.}, language = {en} } @techreport{ClausenStieglitzWloka2023, author = {Clausen, S{\"u}nje and Stieglitz, Stefan and Wloka, Michelle}, title = {Between reality \& fantasy}, series = {Communication insights}, volume = {19}, journal = {Communication insights}, publisher = {Academic Society for Management \& Communication}, address = {Leipzig}, issn = {2749-893X}, doi = {10419/280991}, pages = {21}, year = {2023}, abstract = {Synthetische Medien erm{\"o}glichen die zunehmend automatisierte Erstellung virtueller Influencer, von denen bereits einige Millionen Follower in sozialen Medien gewonnen haben.

We estimate the impact of the reform on the program's effectiveness using samples of participants and non-participants from before and after the reform. To control for time-constant unobserved heterogeneity as well as differential selection patterns based on observable characteristics over time, we combine Difference-in-Differences with inverse probability weighting using covariate balancing propensity scores. Holding participants' observed characteristics as well as macroeconomic conditions constant, the results suggest that the reform was successful in raising employment effects on average. As these findings may be contaminated by changes in selection patterns based on unobserved characteristics, we assess our results using simulation-based sensitivity analyses and find that our estimates are highly robust to changes in unobserved characteristics. Hence, the reform most likely had a positive impact on the effectiveness of the program, suggesting that increasing entry requirements and reducing support increased the program's impacts while reducing the cost per participant.

In a two-source, lagged design field study of 258 leader-follower dyads from different settings, we show that uncertainty moderates the relation between visionary leadership and followers' perceived meaningfulness such that this relation is more strongly positive when uncertainty is high, rather than low. Moreover, we show that with increasing uncertainty, visionary leadership is more negatively related to followers' turnover intentions via perceived meaningfulness. This research broadens our understanding of how visionary leadership may be a particularly potent tool in times of increasing uncertainty.}, language = {en} } @phdthesis{Buss2021, author = {Buss, Martin}, title = {The dark side of visionary leadership}, school = {Universit{\"a}t Potsdam}, year = {2021}, language = {de} } @phdthesis{Bunnenberg2022, author = {Bunnenberg, Philipp}, title = {Finanzmarktrisiken durch ETFs und Closet Indexing}, series = {Schriftenreihe Finanzierung und Banken (SFB)}, journal = {Schriftenreihe Finanzierung und Banken (SFB)}, number = {32}, publisher = {EWP, Edition Wissenschaft \& Praxis}, address = {Berlin}, isbn = {978-3-89673-776-2}, issn = {2751-9562}, doi = {10.3790/978-3-89644-776-0}, school = {Universit{\"a}t Potsdam}, pages = {287}, year = {2022}, abstract = {Die Arbeit ist ein Beitrag zu einer grundlegenden Diskussion der Kapitalmarktforschung, dem messbaren Erfolg „aktiver vs. passiver" Investmentstrategien.

In accordance with this statement, prevalent literature understands digital workplace transformation as a second-order effect of implementing new information technology to increase organisational effectiveness or reach other strategic goals. This paper, in contrast, provides empirical evidence from two remote-first organisations that undergo a proactive rather than reactive digital workplace transformation. The analysis of these cases suggests that new ways of working can be the consequence of an identity change that is a precondition for introducing new information technology rather than its outcome. The resulting process model contributes a competing argument to the existing debate in digital transformation literature. Instead of issuing digital workplace transformation as a deliverable of technological progress and strategic goals, this paper supports a notion of digital workplace transformation that serves a desired identity based on work preferences.}, language = {en} }
