Does social exclusion improve detection of real and fake smiles? A replication study
(2021-01-28)
Research on social exclusion suggests an increased attention of excluded persons to subtle social cues. In one study (N = 32), published in Psychological Science,Bernstein et al. (2008) provided evidence for this idea by showing that participants in the social exclusion condition were better in correctly categorizing a target person’s smile as real or fake. Although highly cited, this finding has never been directly replicated.
The present study aimed to fill that gap. 201 participants (79.1% female) were randomly ...

A Study of Extensions of Classical Summation Theorems for the Series ₃F₂ and ₄F₃ with Applications
(2021-03-16)
Very recently, Masjed-Jamei & Koepf [Some summation theorems for generalized hypergeometric functions, Axioms, 2018, 7, 38, 10.3390/axioms 7020038] established some summation theorems for the generalized hypergeometric functions. The aim of this paper is to establish extensions of some of their summation theorems in the most general form. As an application, several Eulerian-type and Laplace-type integrals have also been given. Results earlier obtained by Jun et al. and Koepf et al. follow special cases of our main findings.

Laser Powder Bed Fusion Processing of Fe-Mn-Al-Ni Shape Memory Alloy—On the Effect of Elevated Platform Temperatures
(2021-01-20)
In order to overcome constraints related to crack formation during additive processing (laser powder bed fusion, L-BPF) of Fe-Mn-Al-Ni, the potential of high-temperature L-PBF processing was investigated in the present study. The effect of the process parameters on crack formation, grain structure, and phase distribution in the as-built condition, as well as in the course of cyclic heat treatment was examined by microstructural analysis. Optimized processing parameters were applied to fabricate cylindrical samples ...

Full-scale testing of adhesively bonded timber-concrete composite beams
(2021-09-07)
This paper presents new findings on adhesively bonded timber-concrete composites with prefabricated concrete parts. Hereby, timber and concrete are bonded solely with adhesive and no metallic connectors have been used. Because the achievement of a continuous bond proved to be a critical point in past studies, special attention is given to that issue. The application procedure of the adhesives is investigated in small-scale bond samples and the manufacturing process in full-scale composite beams with a span of 8 m and ...

Suitability of Slower Growing Commercial Turkey Strains for Organic Husbandry in Terms of Animal Welfare and Performance
(2021-01-06)
Intensive turkey production with fast growing strains is often critically discussed regarding animal welfare problems. Studies evaluating the welfare status of both organic and less intensive selected turkey strains are limited, except in the slightly slower growing Kelly Broad Breast Bronze (Kelly). The aim of this study was to assess the welfare of turkeys from two strains with further decreased growth rate, Hockenhull Large Bronze (HoBr) and Hockenhull Black (HoBl), in comparison to Kelly under commercial organic ...

Efficient Solution of Distributed MIP in Control of Networked Systems
(2021-01-25)
Certain classes of optimization‐based control problems stated for networked systems involving hybrid dynamics and logical constraints can be cast into Mixed‐Integer Programming (MIP) problems. Since these belong to the complexity class NP‐hard, the motivation arises to find approximations of the optimal solution by distributed solution efficiently. For the cases that the cost functional is linear or quadratic and the constraints are linear, this paper proposes an alternative to the standard centralized schemes, by ...

Digital transformation: What we have learned (thus far) and what is next
(2021-01-06)
There is certainly a lot of discussion about digital technologies, their transformative nature, and their potentially disruptive impact on business and society. The number of publications on digital technologies and their impact on business and management have risen dramatically. This paper's main objective is to draw attention to practical and research-related views on what we know and what we still need to learn about business and management in the digital era. We do so by combining the insights obtained from ...

Doppelspitzen: Notlösung, Heilsbringer oder innovatives Führungsmodell? Coaching für gelingende Führungstandems
(2021-03-25)
Doppelspitzen werden in der aktuellen Führungsdebatte kontrovers diskutiert. Wissenschaftliche Erkenntnisse zur Arbeit von Führungstandems sind rar. Bisherige Coachingkonzepte befassen sich schwerpunktmäßig mit dem Konfliktcoaching von Doppelspitzen. In dem vorliegenden Beitrag wird den Fragen nachgegangen, welche Gelingensfaktoren und Herausforderungen es bei geteilter Leitung gibt und wie die Potenziale von Führungstandems durch (präventives) Coaching gehoben werden können.

Zum Forschungsstand über Ansätze des Dual Career Coachings
(2021-04-13)
Der vorliegende Artikel zeigt den Forschungsstand zur Beratung von Dual Career Couples (DCCs) anhand von zehn theoretisch, empirisch und praxeologisch entwickelten Ansätzen auf. Zunächst wird die Bedeutung des Phänomens DCCs für die Karriereberatung konturiert und anschließend vor dem Hintergrund gesellschaftlicher Transformationsprozesse eingeordnet. Die Einführung eines triadisch konzeptualisierten Beratungsraums schafft einen Rahmen, der eine vergleichende Darstellung und Einordnung der zehn Ansätze ermöglicht. ...
