Subject and Methods A systematic search of relevant studies was conducted in multiple databases. Randomized controlled trials (RCTs), cluster-randomized controlled trials (cRCTs) and controlled before–after studies (CBAs) were included based on the following criteria: interventions that addressed supervisors, to raise awareness for the importance of health issues, teach mindfulness practices for conscious awareness, reduce stress and promote resources at the level of individual behavior, and evaluated the effect on at least one outcome of psychomental stress, absenteeism and well-being on the employee level. Results Of 6126 publications retrieved, ten studies were identified for analysis. Significant effects of leadership training were reported on exhaustion tendency, self-reported sickness absence, work-related sickness absence and job satisfaction in studies comparing health-oriented training programs to no intervention. Studies comparing health-oriented leadership training to other training did not report significant effects. Risk of bias was judged to be high in seven studies and unclear in three studies. Conclusion Evidence for the effectiveness of health-oriented leadership interventions on employees’ stress, absenteeism or well-being is judged to be low, clearly indicating the need for more and higher-quality research. }}, author = {{Dannheim, Indra and Ludwig-Walz, Helena and Buyken, Anette and Grimm, Valerie and Kroke, Anja}}, issn = {{2198-1833}}, journal = {{Journal of Public Health}}, keywords = {{Public Health, Environmental and Occupational Health}}, number = {{12}}, pages = {{2777--2789}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Effectiveness of health-oriented leadership interventions for improving health and wellbeing of employees: a systematic review}}}, doi = {{10.1007/s10389-021-01664-1}}, volume = {{30}}, year = {{2021}}, } @article{46135, author = {{Schall, Johannes and Deconinck, Marielle and Bart, Nikolai and Florian, Matthias and Helversen, Martin and Dangel, Christian and Schmidt, Ronny and Bremer, Lucas and Bopp, Frederik and Hüllen, Isabell and Gies, Christopher and Reuter, Dirk and Wieck, Andreas D. and Rodt, Sven and Finley, Jonathan J. and Jahnke, Frank and Ludwig, Arne and Reitzenstein, Stephan}}, issn = {{2511-9044}}, journal = {{Advanced Quantum Technologies}}, keywords = {{Electrical and Electronic Engineering, Computational Theory and Mathematics, Condensed Matter Physics, Mathematical Physics, Nuclear and High Energy Physics, Electronic, Optical and Magnetic Materials, Statistical and Nonlinear Physics}}, number = {{6}}, publisher = {{Wiley}}, title = {{{Bright Electrically Controllable Quantum‐Dot‐Molecule Devices Fabricated by In Situ Electron‐Beam Lithography}}}, doi = {{10.1002/qute.202100002}}, volume = {{4}}, year = {{2021}}, } @article{41338, abstract = {{AbstractThis study explains how manufacturers tackle the critical managerial challenge of transforming a product-focused sales force to undertake solution selling.

In several kinds of sports, deceptive actions are used to hinder the anticipation performance of an opponent. During a head fake in basketball, a player turns the head to one side but passes the ball to the other side. A pass with a head fake generates a head-fake effect in the observer, which is characterized by slower and more error-prone responses to the pass direction as compared to passes without a head fake. Whereas the head-fake effect has been replicated several times, the question of its origin with dynamic stimuli has not been answered yet. The present study includes four experiments, which are conducted to examine the perceptual-cognitive mechanism underlying the effect by using the model of dimensional overlap ( Kornblum et al., 1990 ) and the additive factors logic ( Sternberg, 1969 ). Results point to multiple processes contributing to the head-fake effect for dynamic stimuli, which operate not only at a perceptual level but also at a level of response selection. }}, author = {{Polzien, Andrea and Güldenpenning, Iris and Weigelt, Matthias}}, issn = {{1618-3169}}, journal = {{Experimental Psychology}}, keywords = {{General Psychology, Arts and Humanities (miscellaneous), Experimental and Cognitive Psychology, General Medicine}}, number = {{6}}, pages = {{349--363}}, publisher = {{Hogrefe Publishing Group}}, title = {{{Examining the Perceptual-Cognitive Mechanism of Deceptive Actions in Sports}}}, doi = {{10.1027/1618-3169/a000503}}, volume = {{67}}, year = {{2021}}, } @article{45587, author = {{Habla, Wolfgang and Huwe, Vera and Kesternich, Martin}}, issn = {{1361-9209}}, journal = {{Transportation Research Part D: Transport and Environment}}, keywords = {{General Environmental Science, Transportation, Civil and Structural Engineering}}, publisher = {{Elsevier BV}}, title = {{{Electric and conventional vehicle usage in private and car sharing fleets in Germany}}}, doi = {{10.1016/j.trd.2021.102729}}, volume = {{93}}, year = {{2021}}, } @article{42713, abstract = {{The development of motor competencies is necessary for participation in the culture of sport, exercise, and physical activity, which in turn supports the development of a healthy lifestyle.

This article describes an intervention program for promoting basic motor competencies in middle childhood (around 6 to 10 years of age). The intervention was investigated in a longitudinal study from June 2019 to January 2020 (n = 200; 58% girls, M = 8.84 years, SD = 0.63) at three primary schools. The intervention was conducted once a week in physical education (PE). The comparison group participated in regular PE. The intervention showed significant effects on basic motor competencies in object movement but not in self-movement. The results demonstrate that positive effects on basic motor competencies can be achieved with the help of a relatively simple intervention.

For multi-material joints of metals and thermoplastic composites thermally assisted clinching processes with advanced tool concepts are well developed. The material-specific properties of fibre-reinforced thermoplastics have a significant influence on the joining process and the resulting material structure in the joining zone. For this reason, it is important to investigate these influences in detail and to understand the phenomena occurring during the joining process. Additionally, this provides the basis for a validation of a numerical simulation of such joining processes. In this paper, the material structure in a joint resulting from a thermally assisted clinching process is investigated. The joining partners are an aluminium sheet and a thermoplastic composite (organo sheet). Using computed tomography enables a three-dimensional investigation that allows a detailed analysis of the phenomena in different joining stages and in the material structure of the finished joint.

The field became conductive to ethnographic, observational and videographic studies of human-device interaction. Conversation-analytic HCI became possible. That said, this new wave of researchers was never truly able to dethrone the psychological common sense of the field. With recent developments in both the technical-sensorial capabilities and outward actuational range of embodied virtual agents, the field of HCI has once again returned to the question of the sequential unfolding of the interaction between users and intelligent agents, and the multimodal interactional repertoire that is deployed throughout.
