All power to the reviewers: British sociology under two-level supervision of the Research Excellence Framework
(2023-03-16)
Our study investigates the impact of the British Research Assessment Exercise in 2008 and Research Excellence Framework in 2014 on the diversity and topic structure of UK sociology departments from the perspective of habitus-field theory. Empirically, we train a Latent Dirichlet allocation on 819,673 abstracts stemming from the journals in which British sociologists submitted at least one paper in the Research Assessment Exercise 2008 or Research Excellence Framework 2014. We then employ the trained model on the 4822 ...

Experimentelle Untersuchungen von Wärmerohrsystemen für den Einsatz in elektrischen Arbeitskraftmaschinen
(2023-03-01)
Mit dem Ziel die Effizienz elektrischer Arbeitskraftmaschinen durch ein innovatives Kühlsystem zu erhöhen, wird ein Wärmetransportsystem auf Basis von Wärmerohren entwickelt und analysiert. Die Leistungsfähigkeit des Systems bei Variation des Temperaturbereichs und des zugeführten Wärmestroms sowie der Einfluss der Rotation werden experimentell untersucht. Der Wärmewiderstand des Systems wird im Vergleich zu reiner Wärmeleitung um 98 % reduziert. Die Rotation des Systems hat keinen signifikanten Einfluss auf den ...

Das digitale Sportangebot „Get Up – Stand Up – Move Up“ während der Covid-19-Pandemie: eine Interviewstudie mit teilnehmenden Grundschulkindern
(2023-04-18)
Die Covid-19-Pandemie führte während des zweiten Lockdowns zu einer Reduktion der körperlichen Aktivität der Kinder in Deutschland. Um den erschwerten Möglichkeiten, sich als Kind zu bewegen, etwas entgegenzusetzen, wurde ein digitales Sportangebot initiiert. Dieses nahm insbesondere die Befriedigung der psychologischen Grundbedürfnisse in den Blick und richtete sich an Kinder im Grundschulalter. Weiterhin stand die Vermittlung von Freude an der Bewegung im Fokus. Fünf bis sechs Wochen nach Projektstart wurden acht ...

Stakeholder roles in sustainable supply chain management: a literature review
(2022-10-25)
Since ecological deterioration and social discrepancy are intensifying, multiple stakeholders are driving companies to incorporate sustainability in their supply chains. Thus, integrating non-traditional supply chain stakeholders, such as non-governmental organizations and competitors, in supply chain practices is essential for achieving a more sustainable supply chain. Hence, this research aims to show how stakeholders and their roles are related to sustainable supply chain management practices. A systematic literature ...

Valence sound symbolism across language families: a comparison between Japanese and German
(2022-12-13)
Vowels are associated with valence, so that words containing /i/ (as in English meet) compared with /o/ (as in French rose) are typically judged to match positively valenced persons and objects. As yet, valence sound symbolism has been mainly observed for Indo-European languages. The present research extends this to a comparison of Japanese-speaking and German-speaking participants. Participants invented pseudo-words as names for faces with different emotional expressions (happy vs. neutral vs. sad vs. angry). For ...

Electrostatic Body Forces and their Implications for Cracks
(2023-03-24)
A Griffith-type crack in a dielectric solid under electromechanical loading is investigated by numerically solving the combined boundary value problem. The focus is on the contribution of electrostatically induced body forces, coming along with the still controversially discussed Maxwell stress tensor, to the crack tip loading. A 1/r-singularity of compressive stress is found to evolve at the crack tip, however, just being dominant over the mechanically induced 1/√r-behavior within a very small region

Effect of Thermo-Mechanically Activated Precipitation on the Hot Deformation Behavior of High Strength Aluminum Alloy AA7075
(2022-09-26)
The present study investigates the effect of two different microstructural conditions on the hot deformation behavior of precipitation-hardenable AA7075 by compression tests ranging from 200 °C to 350 °C and strain rates from 0.1 s-¹ to 10 s-¹. The first condition is solution heat-treated and quenched in water, whereas the second condition is achieved by subsequent artificial aging and stabilization for 24 h at the respective intended deformation temperature. Both conditions indicate an increase in flow stress with ...

Investigating Adsorption-Based Atmospheric Water Harvesting Potential for Pakistan
(2022-10-03)
Atmospheric water harvesting (AWH) can provide clean and safe drinking water in remote areas. The present study provides a comprehensive review of adsorption-based AWH by using the scientometric approach. The publication types are mainly composed of articles and reviews, accounting for 75.37% and 11.19% of the total, respectively. Among these publications, ~95.1% were published in English and came from 154 different journals which demonstrates that researchers have shown a great interest in this field. However, much ...

An insight into the runs of homozygosity distribution and breed differentiation in Mangalitsa pigs
(2022-10-18)
Mangalitsa pigs exhibit three distinct coat color patterns based on which they are described as Red, Blond, and Swallow-bellied. The current study investigated genome-wide diversity and selection signatures in the three breeds using fixation index, runs of homozygosity and population structure analyses. The analyses were originally based on quality-controlled data on 77 Mangalitsa animals from Germany, including 23 Blond, 30 Swallow-bellied and 24 Red Mangalitsa genotyped with a customized version of the ProcineSNP60 ...

Kann die Schule die Selbstwertentwicklung Jugendlicher positiv beeinflussen?
(2022-02-22)
Die drei Grundbedürfnisse Autonomie, Kompetenzwahrnehmung und soziale Eingebundenheit wurden wiederholt als mögliche Determinanten eines globalen Selbstwerts untersucht. Doch nur wenige dieser Untersuchungen erfassen explizit eine mehrjährige Selbstwertentwicklung und die Rolle der Schule bei der Erfüllung der Grundbedürfnisse während der Adoleszenz. In der vorliegenden Studie werden die Angaben von 334 Schüler*innen zur Gewährung von Autonomie durch die Lehrkräfte sowie deren Kompetenzrückmeldungen und die soziale ...
