Cross-organizational collaboration and the exchange of process data are indispensable for many processes in federally organized governments. Conventional IT solutions, such as cross-organizational workflow management systems, address these requirements through centralized process management and architectures. However, such centralization is difficult and often undesirable in federal contexts. One alternative solution that emphasizes decentralized process management and a decentralized architecture is the blockchain solution of Germany’s Federal Office for Migration and Refugees. Here, we investigate the architecture of this solution and examine how it addresses the requirements of federal contexts. We find that the solution’s architecture resembles an improvement and cross-organizational adaption of an old architectural paradigm, the enterprise service bus. [less ▲]

Nematic and columnar phases of lyotropic chromonic liquid crystals (LCLCs) have been long studiedfor their fundamental and applied prospects in material science and medical diagnostics. LCLC phasesrepresent different self-assembled states of disc-shaped molecules, held together by noncovalentinteractions that lead to highly sensitive concentration and temperature dependent properties. Yet,microscale insights into confined LCLCs, specifically in the context of confinement geometry andsurface properties, are lacking. Here, we report the emergence of time dependent textures in staticdisodium chromoglycate (DSCG) solutions, confined in PDMS-based microfluidic devices. We use acombination of soft lithography, surface characterization and polarized optical imaging to generateand analyze the confinement-induced LCLC textures, and demonstrate that over time, herringboneand spherulite textures emerge due to spontaneous nematic (N) to columnar M-phase transition,propagating from the LCLC-PDMS interface into the LCLC bulk. By varying the confinementgeometry, anchoring conditions and the initial DSCG concentration, we can systematically tune thetemporal dynamics of the N to M-phase transition and textural behaviour of the confined LCLC. Sincestatic molecular states register the initial conditions for LC flows, the time dependent boundary andbulk conditions reported here suggest that the local surface-mediated dynamics could be central inunderstanding LCLC flows, and in turn, the associated transport properties of this versatile material.

Workplace bullying is a phenomenon that can have serious detrimental effects on health, work-related attitudes, and the behavior of the target. Particularly, workplace bullying exposure has been linked to lower level of general well-being, job satisfaction, vigor and performance, and higher level of burnout, workplace deviance, and turnover intentions. However, the psychological mechanisms behind these relations are still not well understood. Drawing on psychological contract and self-determination theory, we hypothesized that perceptions of contract violation and the frustration of basic needs mediate the relationship between workplace bullying exposure and well-being, attitudinal, and behavioral outcomes. Self-reported data were collected among employees with different working backgrounds (N = 1,257) via Amazon’s Mechanical Turk in an online survey. Results showed that feelings of contract violation and frustration of basic needs accounted for unique variation in well-being, work satisfaction, burnout, vigor, and turnover intentions, pointing to individual contributions of both psychological mechanisms. However, when controlled for frustration of basic needs, feelings of psychological contract violation were no longer a mediator between workplace bullying exposure and work performance. Helping employees to deal effectively with workplace bullying exposure might buffer its negative effects and reduce their experienced frustration of basic needs, preserving their well-being, vigor, and work performance and, eventually, prevent burnout. The present study is the first to concurrently elucidate the proposed psychological mechanisms and unique contributions of psychological contract violation and frustration of basic needs in the context of workplace bullying.

Background Fibromyalgia is characterized by widespread musculoskeletal pain and often accompanied by cognitive and emotional problems. Adaptation to fibromyalgia may therefore also rely on one's ability to regulate emotional problems. In this study, we examined two indices of emotion regulation, that is, (a) affective instability, involving frequent large fluctuations in self-reported affect, and (b) resting heart rate variability (HRV). 45.4 years; 39 females) and 46 matched healthy controls (M-age = 44.9 years; 37 females). Heart rate was monitored under resting conditions to derive HRV. Subsequently, participants completed an electronic end-of-day diary for 14 consecutive days assessing daily levels of pain, disability, negative affect (NA) and positive affect (PA). Affective instability was operationalized as the mean square of successive differences in daily mood. Results Results indicate increased levels of NA instability and reduced levels of HRV in patients with fibromyalgia in comparison with healthy controls. Furthermore, HRV and NA instability were inversely related. Finally, in patients, higher NA instability was related to increased pain disability. Conclusions Current findings support the idea that patients with fibromyalgia are confronted with fluctuating emotions. These results may have important implications for treatment as they provide support for the use of emotion regulation skills training in patients with fibromyalgia to impact upon NA instability. Significance This study provides novel insight in the link between emotion regulation indices,that is, heart-rate variability and negative affective (NA) instability, in patients with fibromyalgia, and presents evidence for differences in both emotion regulation indices between patients with fibromyalgia and healthy people. Furthermore, results link increased NA instability with increased levels of daily disability in patients with fibromyalgia. Together, these findings offer support for a key role of emotion regulation in fibromyalgia outcomes, providing pathways for clinical practice. [less ▲]

Subjectivation has become central in the field of social, cultural and educational studies to examine the effects of power on the individual. However, there is a lack of theorizing subjectivation concerning not only individuals, but collectives. In this article the concept of the 'couple' regarding subjectivation will be examined. Furthermore, an empirical approach will be presented, exemplified by a study on double-income-couples with a child categorized as disabled. The findings highlight the interdependencies and contradictions that arise in the subjectivation of two individuals addressed as a couple [less ▲]

This chapter reviews the behavioral and neuroimaging scientific literature on the cognitive consequences of playing various genres of video games. The available research highlights that not all video games have similar cognitive impact; action video games as defined by first- and third-person shooter games have been associated with greater cognitive enhancement, especially when it comes to top-down attention, than puzzle or life-simulation games. This state of affairs suggests specific game mechanics need to be embodied in a video game for it to enhance cognition. These hypothesized game mechanics are reviewed; yet, the authors note that the advent of more complex, hybrid, video games poses new research challenges and call for a more systematic assessment of how specific video game mechanics relate to cognitive enhancement.

What role do generative models play in generalization of learning in humans? Our novel multi-task prediction paradigm—where participants complete four sequence learning tasks, each being a different instance of a common generative family—allows the separate study of within-task learning (i.e., finding the solution to each of the tasks), and across-task learning (i.e., learning a task differently because of past experiences). The very first responses participants make in each task are not yet affected by within-task learning and thus reflect their priors. Our results show that these priors change across successive tasks, increasingly resembling the underlying generative family. We conceptualize multi-task learning as arising from a mixture-of-generative-models learning strategy, whereby participants simultaneously entertain multiple candidate models which compete against each other to explain the experienced sequences. This framework predicts specific error patterns, as well as a gating mechanism for learning, both of which are observed in the data. [less ▲]

Emotion regulation is a human adaptation process with important implications for daily life. Two specific emotion regulation strategies were the principle areas of study: reappraisal (cognitive change in which individuals adapt their state of mind about a given situation) and expressive suppression (response modulation in which individuals change their emotional response after its initiation). The Emotion Regulation Questionnaire (ERQ), that captures individual tendencies to reappraise and to suppress the expression of emotions, was also developed. Response modulation strategy was analyzed by considering two distinct processes: expressive suppression (down-regulation) and expressive enhancement (up-regulation). This latter modulation process has been less frequently studied by researchers. The present study investigates the psychometrical properties, individual differences and correlates of a French adapted version of the ERQ, which comprises reappraisal and the two response modulation tendencies – expressive suppression and expressive enhancement. Based on the initial ERQ, new items were created and added to the scale. The three-factor structure of the ERQ adapted was confirmed. As expected, emotion regulation is linked to individual differences: the tendency to reappraise has a positive low correlation with age; and men are significantly more disposed to suppress and to enhance than women. Finally, the tendency to suppress the expression of emotions is negatively correlated with extraversion, and the disposition to enhance the expression of emotions is negatively correlated with conscientiousness.
