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 ...

Can carbon payments improve profitability of traditional conventional and organic cocoa agroforests? A case study in the Eastern Region of Ghana
(2023-03-16)
This study investigates the carbon (C) sequestration of traditional cocoa agroforestry systems in the Eastern Region of Ghana and the theoretical impact of CO₂ emission rights trading on their profitability. The study was conducted in four villages of Suhum Municipality, two each with either conventional or organic cocoa cultivation systems. Profitability was calculated using net present value of net cashflow (NPV), benefit cost ratio (BCR), and modified internal rate of return (MIRR). Carbon revenues were calculated ...

Lifetime Prediction with Combined Hygro-Thermo-Mechanical Influences on Thick Layer Adhesives
(2023-05-31)
Semi-structural bonded joints of steel components are exposed to long-term stresses in addition to water diffusion, temperature changes and varying external forces during operation. These hygro-thermomechanical loadings lead to successive degradation of stiffness and strength due to damage resulting from chemical aging and fatigue processes, causing failure of the bonded joint when its service life is reached. In the following contribution, a methodology is presented to predict the service life of hygro-thermo-mechanically ...

Sustainable value in the fashion industry: A case study of value construction/destruction using digital twins
(2022-12-14)
New technologies—especially the emergence of digital fashion and a growing interest in creating digital twins (DTs)—are expected to alter existing value chains in the fashion industry as DT technology triggers a redesign of value creation processes. This qualitative case study demonstrates how and to what extent the development of DTs in the fashion industry addresses the sustainability needs of various stakeholders in both real-world and virtual-reality settings. The article examines the possibilities, benefits, and ...

Stuck in between. Phenomenology’s Explanatory Dilemma and its Role in Experimental Practice
(2022-10-22)
Questions about phenomenology’s role in non-philosophical disciplines gained renewed attention. While we claim that phenomenology makes indispensable, unique contributions to different domains of scientific practice such as concept formation, experimental design, and data collection, we also contend that when it comes to explanation, phenomenological approaches face a dilemma. Either phenomenological attempts to explain conscious phenomena do not satisfy a central constraint on explanations, i.e. the asymmetry between ...

Integrated reporting of environmental, social, and governance and financial data: Does the market value integrated reports?
(2020-01-09)
The concept of reporting nonfinancial information within the annual report, so‐called Integrated Reporting (IR) is a rising topic in reporting practice. Supporters claim that IR provides a better view regarding the value creation of a firm.
This study investigates the value relevance of IR and the influence of certain characteristics such as assurance. Thus, this paper contributes to the existing literature by examining the actual advantages for firms when adopting an IR approach.
The Ohlson model is applied for ...
