Mapping established psychopathology scales onto the Hierarchical Taxonomy of Psychopathology (HiTOP)
(2022-09-26)
The Hierarchical Taxonomy of Psychopathology (HiTOP) organizes phenotypes of mental disorder based on empirical covariation, offering a comprehensive organizational framework from narrow symptoms to broader patterns of psychopathology. We argue that established self-report measures of psychopathology from the pre-HiTOP era should be systematically integrated into HiTOP to foster cumulative research and further the understanding of psychopathology structure. Hence, in this study, we mapped 92 established psychopathology ...

Predictors of post-stroke depression: Validation of established risk factors and introduction of a dynamic perspective in two longitudinal studies
(2023-02-13)
Introduction: Cerebral insults lead in many cases not only to cognitive impairment but also to disturbed emotionality. After stroke, one in three survivors develops a depression which impacts quality of life and rehabilitation. Meta-analyses have identified five main predictors of post-stroke depression (PSD): history of mental disorder, stroke severity, physical disability, cognitive impairment, and social support. However, these five established variables have never been conjointly investigated in a sample of stroke ...

Motiviert begonnen, erfolgreich beendet?
(2021-03-01)
Die Bedeutung der Studienwahlmotivation für den Studien- und Berufserfolg von Lehrkräften wird vielfach betont, wurde bislang jedoch nicht hinreichend untersucht. So ist zwar bekannt, dass die Studienwahlmotivation mit leistungsrelevanten Merkmalen wie der Nutzung von Lernstrategien in Verbindung steht, unklar ist jedoch, inwiefern die Studienwahlmotivation darüber hinaus auch Leistungsmaße beeinflusst. Im vorliegenden Beitrag wird die prognostische Validität der Studienwahlmotivation auf zwei Leistungsmaße geprüft: ...

Research topic flows in co-authorship networks
(2022-10-11)
In scientometrics, scientific collaboration is often analyzed by means of co-authorships. An aspect which is often overlooked and more difficult to quantify is the flow of expertise between authors from different research topics, which is an important part of scientific progress. With the Topic Flow Network (TFN) we propose a graph structure for the analysis of research topic flows between scientific authors and their respective research fields. Based on a multi-graph and a topic model, our proposed network structure ...

Consumers' body image expressions: Reflection of a Snow White or an Evil Queen
(2023-03-17)
Introduction: The aim of this paper is to explore how minimal-self impacts the body image, projecting it as a reflection of one's approach toward their health and mental well-being.
Methods: The study takes qualitative data from two countries India and Germany and draws on a qualitative study of 20 individuals who are involved in some kind of physical activity for a long time. This paper examines the body image perspectives from Grimms Brothers fairytale characters showcasing fit and healthy perspectives on Snow ...

Normative and cognitive influences on female entrepreneurial reluctance at the base of the pyramid - an explorative study of cleaning ladies in Istanbul
(COMSATS, Inst. of Information Technology, 2013)
Previous research has considered entrepreneurship as a way out of poverty and as a chance to foster economic growth. Moreover, specifically start-ups headed by women have played an important role in the economic development and it has been argued that gender-related issues, amongst others, play a significant role for the performance of a country or region. Against this background, this qualitative study explores desires, reluctances and constraints toward entrepreneurial activities of a comparably homogenous group ...

Happy growers! Relationship quality in the German organic apple chain
(IFAMA, 2014)
Relational factors between supply chain actors have been acknowledged to contribute significantly to competitiveness. With the example of the German market for organic apples the suitability of the concept of the Relational View for explaining competitiveness was investigated. Structured interviews were conducted with selected actors of the supply chain. Actors at all levels of the supply chain proved to be highly committed and described their business relations as satisfying and trustful. Strong vertical and horizontal ...

Giving Is Nicer than Taking: Preschoolers Reciprocate Based on the Social Intentions of the Distributor
(2016-01-25)
Recent research has found that even preschoolers give more resources to others who have previously given resources to them, but the psychological bases of this reciprocity are unknown. In our study, a puppet distributed resources between herself and a child by taking some from a pile in front of the child or else by giving some from a pile in front of herself. Although the resulting distributions were identical, three- and five-year-olds reciprocated less generously when the puppet had taken rather than given resources. ...

Effect of Auger recombination and leakage on the droop in InGaN/GaN quantum well LEDs
(Optical Society of America, 2014)
We investigate the effect of the epitaxial structure and the acceptor doping profile on the efficiency droop in InGaN/GaN LEDs by the physics based simulation of experimental internal quantum efficiency (IQE) characteristics. The device geometry is an integral part of our simulation approach. We demonstrate that even for single quantum well LEDs the droop depends critically on the acceptor doping profile. The Auger recombination was found to increase stronger than with the third power of the carrier density and has ...

Spatio-temporal patterns of herbage availability and livestock movements: A cross-border analysis in the Chinese-Mongolian Altay
(Springer, 2016-07-04)
Due to increasing population and the recent implementation of policies to intensify the use of land and water resources, the transhumant pastoral systems in the Chinese-Mongolian Altay-Dzungarian region are rapidly changing, leading to modifications of herd size, herd composition and spatial distribution of livestock grazing. This may have major consequences for the supply and quality of rangeland biomass. Despite similar topographic settings, the socio-political framework for Chinese and Mongolian pastoralists differs ...
