We focus on three facets that are of special importance during change: coping with the change, resisting the change, and leading the change. For each facet, we present relevant quantitative and qualitative studies; and in a final section, we derive implications for employees, leaders, and organisations. In regards to coping with change, we focus on the stress-buffering effects of humour. High-humour individuals maintain higher levels of positive affect in stressful situations and appraise a potentially stressful event as a positive challenge rather than a threat. In regards to resisting change, we show that aggressive humour can be an indicator of serious distress and a means to express resistance towards authority or aspects of the change process. In regards to leading change, we point out how effective leaders may utilise humour to manage followers' emotions in order to increase positive affect and to reduce perceived threat associated with change. We conclude by suggesting how humour can be used as a diagnostic tool, to foster a humour-supportive climate, to improve communication strategies, and to support an error management culture.}, language = {en} } @article{Hessel2015, author = {Hessel, Franz}, title = {Genetisch stratifizierende Medizin in der Onkologie}, series = {Blickpunkte Mensch Gesellschaft Sicherheit}, journal = {Blickpunkte Mensch Gesellschaft Sicherheit}, number = {4}, pages = {10 -- 12}, year = {2015}, abstract = {Keine Angabe - No details}, language = {de} } @article{SchermulyMeyer2015, author = {Schermuly, Carsten C. and Meyer, Bertolt}, title = {Good relationships at work: The effects of Leader-Member Exchange and Team-Member Exchange on psychological empowerment, emotional exhaustion, and depression}, series = {Journal of Organizational Behavior}, volume = {37}, journal = {Journal of Organizational Behavior}, number = {5}, publisher = {Wiley}, address = {Hoboken, NJ}, pages = {673 -- 691}, year = {2015}, abstract = {Emotional exhaustion and depression pose a threat to employees' psychological health. Social relationships at work are important potential buffers against these threats, but the corresponding psychological processes are still unclear. We propose that the subjective experience of high-quality relationships with supervisors (i.e., Leader-Member Exchange [LMX]) is one of the protective factors against psychological health issues at work and that this effect is mediated by psychological empowerment. We tested these assumptions with two studies (one cross-sectional and one time lagged) on diverse samples of employees from different organizations. The first study employed emotional exhaustion as the outcome measure; the second used depression. Results from both studies support the proposed process by showing that LMX positively affects empowerment, which negatively affects emotional exhaustion (Study 1) and depression (Study 2). Additionally, Study 2 also showed that Team-Member Exchange is as important as LMX for preventing psychological health issues among employees.}, language = {en} } @article{PrietoGonzalezJaedickeSchubertetal.2016, author = {Prieto-Gonz{\´a}lez, Lisardo and Jaedicke, Corvin and Schubert, Johannes and Stantchev, Vladimir}, title = {Fog computing architectures for healthcare: Wireless performance and semantic opportunities}, series = {Journal of Information, Communication and Ethics in Society}, volume = {14}, journal = {Journal of Information, Communication and Ethics in Society}, number = {4}, publisher = {Emerald}, address = {Bingley}, pages = {334 -- 349}, year = {2016}, abstract = {Purpose - The purpose of this study is to analyze how embedding of self-powered wireless sensors into cloud computing further enables such a system to become a sustainable part of work environment. Design/methodology/approach - This is exemplified by an application scenario in healthcare that was developed in the context of the OpSIT project in Germany. A clearly outlined three-layer architecture, in the sense of Internet of Things, is presented. It provides the basis for integrating a broad range of sensors into smart healthcare infrastructure. More specifically, by making use of short-range communication sensors (sensing layer), gateways which implement data transmission and low-level computation (fog layer) and cloud computing for processing the data (application layer). Findings - A technical in-depth analysis of the first two layers of the infrastructure is given to provereliability and to determine the communication quality and availability in real-world scenarios. Furthermore, two example use-cases that directly apply to a healthcare environment are examined,concluding with the feasibility of the presented approach. Practical implications - Finally, the next research steps, oriented towards the semantic tagging and classification of data received from sensors, and the usage of advanced artificial intelligence-based algorithms on this information to produce useful knowledge, are described together with the derived social benefits. Originality/value - The work presents an innovative, extensible and scalable system, proven to be useful in healthcare environments.}, language = {en} } @article{LeibfriedStecker, author = {Leibfried, Stephan and Stecker, Christina}, title = {Sozialpolitik: Bilanz und Perspektiven f{\"u}r Forschung und Lehre an den deutschen Universit{\"a}ten.

This program consists of two phases: in the first phase of the program, graduate students are trained to become job application trainers and in the second phase, the students give trainings to refugees whom they recruit themselves. Given the multiplier effect of this didactic approach, many refugees may be reached. To evaluate the effectiveness of the first phase of the program for the students, we conducted a questionnaire and interview study. Results of the evaluation show the following: based on their past experience, the participants of the program were more likely to be encouraged by their families to help others than the participants in a control group. In addition, they were more motivated to volunteer deliberately and actively. Furthermore, all necessary core competencies for training performance improved over time. We were also able to predict participants' intentions to volunteer and their attitude towards labor market integration of refugees. We discuss challenges of the program's implementation.}, language = {en} } @article{GerlachGockel, author = {Gerlach, Rebecca and Gockel, Christine}, title = {We belong together : belonging to the principal's in-group protects teachers from the negative effects of task conflict on psychological safety}, series = {School Leadership \& Management}, journal = {School Leadership \& Management}, pages = {1 -- 21}, abstract = {Psychological safety is the shared belief that the team is safe for interpersonal risk-taking. Critical team events such as conflict and faultlines (hypothetical lines that split a team into subgroups) should impact psychological safety. Previous research has shown the benefits of task conflict on team outcomes under certain conditions and the consistently negative effects of demographic faultline strength on team outcomes. We propose that being close to the principal (what we call belonging to the principal's in-group) should help attenuate the negative effects of task conflict and faultlines among teachers, because it is associated with a more effective working relationship. In a survey study with 244 teachers from 45 primary schools, we tested the moderating effect of belonging to the principal's in-group vs. belonging to an out-group on the relationships of task conflict and faultlines on psychological safety. Results of multilevel model tests showed that relationship conflict (but not task conflict) and faultlines decreased psychological safety. However, when teachers belonged to the principal's in-group as compared to an out-group, task conflict had no negative effect on psychological safety. We present implications to bridge the negative effects due to subgroup presence, so that psychological safety can become a resource for all.}, language = {en} } @article{Hessel, author = {Hessel, Franz}, title = {Budget impact of computer-based psychotherapy in Germany}, series = {Value in Health}, journal = {Value in Health}, abstract = {Keine Angabe No details}, language = {en} } @article{LopezGonzalezPeredaReyesRomero2017, author = {L{\´o}pez Gonz{\´a}lez, Lisbet Mailin and Pereda Reyes, Illeana and Romero, Osvaldo}, title = {Anaerobic co-digestion of sugarcane press mud with vinasse on methane yield}, series = {Waste Management}, volume = {68}, journal = {Waste Management}, publisher = {Elsvier}, pages = {139 -- 145}, year = {2017}, abstract = {The conversion efficiency of high solids waste digestion as sugarcane press mud (P) may be limited due to hydrolysis step. The option of co-digestion with vinasse, main liquid waste generated from ethanol production, was investigated under batch regime at mesophilic conditions (37.5 ± 1 °C) and the best mixture was evaluated under semicontinuous regime in stirred-tank reactors. The maximum values for methane yield in batch tests were for V75/P25 and V50/P50 mixtures (on basis of the chemical oxygen demand (COD) percentage added in the mixture), with an average value of 246 N mL CH4 g-1 CODfed, which was 13\% higher than that of press mud alone. A highest methane production rate of 69.6 N mL CH4 g-1 CODfed-1 d-1 was obtained for the mixtureV75/P25. During the experiment carried out in CSTR reactors, the organic loading rate (OLR) was increased from 0.5 up to 2.2 g VS L-1 d-1. Methane yields of 365 L CH4 kg-1 VS and biogas productivities of 1.6 L L-1 were obtained in co-digestion, which was 64\% higher in comparison to mono-digestion. The performance of the process in mono-digestion was less stable than in co-digestion, with a significant fall of methane yield to 1.8 kg VS m-3 d-1, and a partial inhibition of the methanogenic archaeas when the OLR was increased up to 2.2 kg VS m-3 d-1. The co-digestion of vinasse with press mud is a good option for the treatment of streams at the alcohol-sugar industry.}, language = {en} } @article{JimenezBarreradeVriezeetal., author = {Jim{\´e}nez, Janet and Barrera, Ernesto L. and de Vrieze, Jo and Boon, Nico and DeMeester, Steven and Spanjers, Henri and Romero, Osvaldo and Dewulf, Jo}, title = {Microbial community dynamics reflect reactor stability during the anaerobic digestion of a very high strength and sulfate-rich vinasse}, series = {Journal of Chemical Technology \& Biotechnology}, volume = {993}, journal = {Journal of Chemical Technology \& Biotechnology}, number = {4}, pages = {975 -- 984}, abstract = {BACKGROUND Microbial community dynamics during the anaerobic digestion of vinasse has been little studied. However, having knowledge about it is essential for early detection of reactor operational difficulties to apply preventive actions. This research studies the microbial community dynamics in the anaerobic digestion of vinasse, linking to experimental observations about product yields and organic matter degradation. RESULTS Methane and sulfide yields decreased with increasing SO42-/COD ratio, while the fraction of organic matter degraded by sulfate reducing bacteria increased from 4.5 ± 0.3\% to 27.1 ± 0.6\%. The archaeal community showed that acetoclastic Methanosaetaceae were little affected by the increase of the SO42-/COD ratio, in contrast to the Methanomicrobiales and Methanobacteriales population, which decreased during the experiment. The total bacterial diversity was influenced mainly by substrate composition, showing that the increase of the SO42-/COD ratio above 0.10 shifted the bacterial community to a lower richness. CONCLUSION These results provide knowledge on the dynamics of the microbial communities, which can be useful to control the anaerobic digestion of sulfate-rich vinasses, showing that reactor stability equates to the higher ratios between total methanogens and total bacteria gene copy numbers, whereas operational difficulties can be associated to lower bacterial richness and higher community organization.}, language = {en} }
