Prediction Model Based on DoE and FTIR Data to Control Fast Setting and Early Shrinkage of Alkaline-Activated Slag/Silica Fume Blended Cementitious Material
(2023-05-31)
This study aims to develop a material-saving performance prediction model for fast-hardening alkali-activated slag/silica fume blended pastes. The hydration process in the early stage and the microstructural properties after 24 h were analyzed using design of experiments (DoE). The experimental results show that the curing time and the FTIR wavenumber of the Si-O-T (T = Al, Si) bond in the band range of 900–1000 cm−¹ after 24 h can be predicted accurately. In detailed investigations, low wavenumbers from FTIR analysis ...

Green in grey: ecosystem services and disservices perceptions from small-scale green infrastructure along a rural-urban gradient in Bengaluru, India
(2023-06-25)
Ecosystem services provided by green infrastructure are often discussed for their potential to address the societal challenges of urbanization. However, green infrastructure, particularly small-scale types (e.g. trees), is vulnerable to loss through urbanization and is often passed over during scientific investigations. Studies on the perceptions of ecosystem services and disservices (hereafter called ecosystem (dis)services) dynamics along the ruralurban gradient are particularly rare in the literature. Therefore, ...

Experimental quantification of site-specific efficiency of Interatomic Coulombic Decay after inner shell ionization
(2023-03-17)
Interatomic Coulombic Decay (ICD) and related interatomic and intermolecular autoionization mechanisms are ubiquitous decay processes of excited atoms and molecules in an environment. It is commonly accepted that the efficiency of ICD of an ionized atom in a cluster increases with an increasing number of nearest neighbors. Here, we present a method for experimental validation of this assumption by a site-specific and quantitative comparison of ICD and its main competitor, Auger decay, in core-level ionized Kr clusters. ...

Agentic and communal narcissism in predicting different types of lies in romantic relationships
(2023-07-03)
Several studies have investigated a potential positive association between agentic narcissism and general dishonesty, revealing both supportive and contradicting evidence. Few have focused on dishonesty within romantic relationships, a phenomenon that occurs in almost all partnerships. With the present research, we first aimed to extend existing literature on narcissism by including its two complementary facets (i.e., agentic and communal narcissism). Second, we aimed to improve the understanding of narcissists’ lying ...

Sustainability performance measurement in risk and uncertainty management: An analysis of base of the pyramid supply chain literature
(2022-10-10)
Risk management in the base of the pyramid (BoP) environment is needed to ensure that firms performance objectives are met. Accordingly, integrating sustainability performance measurement in the supply chain risk management would offer interesting avenues for managing risks in BoP supply chain. Therefore, the paper conceptualizes an intersection between supply chain risk/uncertainty management and sustainable performance measurement. This intersection is then tested by a literature review of 164 BoP SC articles between ...

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 ...
