Beyond disciplinary boundaries
Missing Data Handling via EM and Multiple Imputation in Network Analysis using Glasso and Atan Regularization
The existing literature on missing data handling in psychological network analysis using cross-sectional data is currently limited to likelihood based approaches. In addition, there is a focus on convex regularization, with the missing handling implemented using different calculations in model selection across various packages. Our work aims to contribute to the literature by implementing a missing data handling approach based on multiple imputat…
Applying the human component model of parenting to other primates
The component model of human parenting has been extensively used to study parents’ interactions with their offspring and to examine variation across cultural contexts. The current study applies this model to nonhuman primates to investigate which forms of parenting humans share with other primates and how these interactions change over infants’ first year of life. We repeatedly observed 52 mother-infant pairs, including humans ( N = 11), chimpanz…
Simulation-Based Performance Evaluation of Missing Data Handling in Network Analysis
Network analysis has gained popularity as an approach to investigate psychological constructs. However, there are currently no guidelines for applied researchers when encountering missing values. In this simulation study, we compared the performance of a two-step EM algorithm with separated steps for missing handling and regularization, a combined direct EM algorithm, and pairwise deletion. We investigated conditions with varying network sizes, n…
Exploring weight-related self-monitoring as a potential risk factor for eating disorder symptoms in adults – A systematic review and meta-analysis
Social media and politics on the local level
The local level is highly important for political engagement, as political issues that are relevant to citizens' daily lives are discussed at this level. Therefore, political parties are especially interested in organizing a strong local basis. Yet, empirical research on the local party units is rather scarce, particularly with respect to their social media activities. We do not know whether the local units of political parties are nowadays activ…
Political Communication Patterns of Young Adults in Germany
While the political communication and participation activities of young adults are changing, this is often not adequately captured by research due to a too narrow conceptualization of the phenomenon. Our approach conceptualizes political communication as activities comprising the reception of political content, interpersonal communication regarding political issues and political participation. We incorporated both analog and digital media, as wel…
Constructing the Facets of Altruistic Behaviors (FAB) Scale
Behavior is effectively altruistic to the degree that it is costly for the actor while benefiting others. In a series of preregistered studies, we constructed a 15-item self-report scale assessing three different facets of altruistic behavioral traits: help-giving, moral courage, and peer punishment. Item selection was performed with the help of Ant Colony Optimization (ACO) procedures as implemented in the stuart package for R. Confirmatory fact…
Discussing the effects of prostate cancer beyond biographical disruption and new normalcy
The concept of biographical disruption has been used to explain the experience of a cancer diagnosis. Studies on cancer experience increasingly suggest that people diagnosed in older age may not have such disruptive experiences. Prostate cancer is diagnosed more often in older men and is often considered a disease of old age; furthermore, the signs of illness in prostate cancer and the signs of ageing might become convoluted. With this in mind, t…
Effects of voting advice applications during election campaigns. Evidence from a panel study at the 2014 European elections
Over the last several years, Voting Advice Applications (VAAs) have become an indispensable part of election campaigns in many countries. VAAs are designed to increase the political sophistication of citizens. In this paper we test whether these tools can accomplish this mission. Resorting to self-generated panel data for the 2014 European Election in Germany, we use entropy balancing techniques to deal with the problem of self-selection into the…

Wahlverhalten und Wählerheterogenität
Wahlverhalten und Wahlerheterogenitat
Martin Schultze geht mit seinem Buch der Frage nach, ob und in welchem Ausmass Wählerheterogenität im deutschen Elektorat vorhanden ist. Wählerheterogenität wird dabei durch eine gruppenspezifische Erweiterung des Michigan-Modells analysiert. Anhand von Repräsentativdaten für Deutschland sowie mit Hilfe von Strukturgleichungsmodellen und multiplen Gruppenvergleichen zeigt er, dass ein beträchtliches Ausmaß an Heterogenität im Elektorat vorhanden …
A Cross-Classified CFA-MTMM Model for Structurally Different and Nonindependent Interchangeable Methods
Multirater (multimethod, multisource) studies are increasingly applied in psychology. Eid and colleagues (2008) proposed a multilevel confirmatory factor model for multitrait-multimethod (MTMM) data combining structurally different and multiple independent interchangeable methods (raters). In many studies, however, different interchangeable raters (e.g., peers, subordinates) are asked to rate different targets (students, supervisors), leading to …
Feeling cybervictims’ pain—The effect of empathy training on cyberbullying
As the world's population increasingly relies on the use of modern technology, cyberbullying becomes an omnipresent risk for children and adolescents and demands counteraction to prevent negative (online) experiences. The classroom-based German preventive intervention "Medienhelden" (engl.: "Media Heroes") builds on previous knowledge about links between cognitive empathy, affective empathy, and cyberbullying, among others. For an evaluation stud…

German E-Campaigning and the Emergence of a ‘Digital Voter’? An Analysis of the Users of the Wahl-O-Mat
Within the e-campaigning activities of political actors in Germany, the Wahl-O-Mat has emerged as a popular ‘non-party’ online tool which has been used by millions of voters before elections in Germany. An analysis of the users can provide information about the characteristics of people resorting to this and other types of online pre-election tools. Based on an application-specific approach, hypotheses about the users are developed in light of th…

Acidic lignite mining lakes – a typical case for remediation? Tagebaurestseen – schon bei dar Entstehung ein Sanierungsfall
The formation of lakes after sudden termination of opencast lignite mining in eastern Germany is influenced by massive hydrological problems in the mining area. In spite of restricted surface water availability flooding from external sources is preferable to slow re-ascension of ground-water for geochemical, technological and socio-economical reasons. However, the water quality of the newly formed lakes poses subsequent problems which include eut…
