The transition to CE by public and private organizations can be seen as an entrepreneurial act encompassing their strategic policies, business models, structures, and processes. Little is known about the involvement of employees of organizations making this transition. Therefore, this study investigates the influence of organizations’ commitment to the five CE principles on their employees’ perceptions of the usefulness, ease of implementation, and acceptability of the principles. The method used is exploratory, a mixed-method approach combining PLS-SEM and fsQCA. This research contributes to the field by developing a unified theoretical perspective on the entrepreneurial context. It also highlights the impact of CE principles on organizations that are transitioning to more sustainable development.

Therefore, lower extremity kinematics were analysed in response to decelerative perturbations during running using statistical parametric mapping (SPM). 13 asymptomatic individuals (8 females & 5 males, 28 +/- 3 years, 171 +/- 9 cm, 68 +/- 10 kg) completed an 8-minute running protocol with 30 one-sided perturbations (15 each side) to generate decelerative disturbances. A 3D-motion capture system was employed to record kinematic data. Joint angles of the ankle, knee, and hip in addition to stride duration, stride length and step width were calculated for leading and trailing strides. Results were analysed descriptively, followed by SPM of paired t-tests (P < 0.025). Reactively (after perturbation), perturbations caused decreased hip adduction and stride duration of the leading leg. The trailing leg reacted with ankle inversion, knee and hip flexion, hip abduction, as well as an increase in stride duration and step width (P < 0.025). In preparation for perturbation, the trailing leg reduced ankle dorsiflexion, knee flexion, hip flexion, and adduction. In summary, applied perturbations produced substantial reactive (feedback) and predictive (feedforward) responses of the lower limbs, most apparent in the trailing leg.

BT - the advent of the neo-weberian state in Germany JF - Journal of policy studies N2 - In this contribution, the emergence of the neo-Weberian state (NWS) is analyzed with regard to German public administration. Drawing on the concept of a governance space, which consists of a hierarchy, markets, and networks, we distinguish between four empirical manifestations of the NWS, namely, the NWS as (1) come back of the public/ re-municipalization; (2) re-hierarchization; (3) de-agencification; (4) de-escalation in performance management. These movements can, on the one hand, be interpreted as a (partial) reversal of New Public Management (NPM) approaches and a “swinging back of the pendulum” (see Kuhlmann & Wollmann, 2019) toward public and classical Weberian principles (e.g., hierarchy, regulation, institutional re-aggregation). This reversal re-strengthened the hierarchy within the overall governance space to the detriment of, but without completely replacing, market mechanisms and networks. NPM’s failure to deliver what it promised and its inappropriateness as a response to more recent challenges connected to crises and wicked problems have engendered a partial return of the public and a move away from the economization logic of NPM. On the other hand, post-NPM reversals and managerial de-escalation gave rise to hybrid models that merge NPM and classic Weberian administration. While some well-functioning combinations of NPM and Weberianism exist, the hybridization of “old” and “neo” elements has also provoked ambivalent and negative assessments regarding the actual functioning of the NWS in Germany. Our analysis suggests that the NWS is only partially suitable as a model for reform and future administrative modernization, largely depending on the context surrounding reform and implementation practices.

However, there are no studies to date that examine the effect of such use on peer interactions and the occurrence of prosocial behavior in peers. For parents, it has been found that when using digital media only few parents respond responsively to their children's attempts at interaction and also very rarely, they communicate with them verbally and nonverbally. In the present study, we investigated how playing a game in a digital versus analog form influences in-teractions (especially prosocial behavior) of peers. We used an experimental situation, where 24 dyads of 4-10-year-old children were examined. Each of the dyads was randomly assigned to a condition where they played either a digital or analog game together. Various interaction parameters and prosocial behavior during and after the game were analyzed. Results show that children in the analog condition communicated verbally with each other more often, responded more often to interaction attempts of their partners and showed less often negative forms of inter-action and more often positive forms of interaction than children in the digital condition. However, the type of medium had no influence on prosocial behavior after the game situation. These results suggest that the format of a game (digital vs. analog) has a decisive influence on peer interactions concerning their communication during but not their prosocial behavior after the game situation.

Although, the Pregnancy Physical Activity Questionnaire (PPAQ) has been validated for use in assessing PA in pregnant women. However, understanding the knowledge and participation levels of PA in pregnant women in the underdeveloped regions of Ghana is of clinical relevance to foster education and promotion of PA. In Ghana, pregnant women believe the "myth" (mostly in rural areas and underdeveloped regions) that exercising in the first trimester might lead to miscarriage. Thus, the main objective of this study was to investigate the extent of knowledge and participation levels in PA among pregnant women in Ho, Ghana using a self-developed questionnaire which consisted of some questions adapted from the PPAQ. MethodsSeventy-seven (n = 77) pregnant women between the ages of 18-50 years were recruited from three hospitals across the Ho municipality of Ghana. A self-developed questionnaire which consisted of some questions taken from the PPAQ was administered to participants under the researchers' supervision. Spearman's correlation analysis was used to find the association between the level of participation in PA, knowledge of PA and gestational age among pregnant women. Results From the total participants (n = 77) recruited, 57 (74%) of the participants scored high in PA knowledge. Most of the participants 48 (62.3%) answered that PA promotes healthy pregnancy. Participants who reported barriers to PA during pregnancy were no exercise habits 51 (66.2%), having no time 17 (22.1%) and fear of miscarriage 9 (11.7%). There was a significant (p < 0.05) association between the level of participation and gestational age. No significant (p > 0.05) association between the level of participation and knowledge of PA was observed. Conclusion There is a high level of knowledge of PA among pregnant women in Ho, Ghana. However, most pregnant women rather engage in PA as their gestational age increases. Thus, to foster sustainable exercise participation during pregnancy, all healthcare providers saddled with the responsibility of providing maternal healthcare must strengthen the education and promotion of exercise and PA among pregnant women in Ho, Ghana.

Even though bereaved siblings can be identified as a high-risk group, evidence-based interventions for this bereavement group are still missing. Aim: To evaluate the treatment effects of an internet-based writing intervention for bereaved siblings aged 16-65 years. Design: A two-armed randomized controlled trial (DRKS00011514) compared the intervention to a waiting list control group. The 6-week intervention consisted of six structured writing assignments that were based on cognitive behavioral therapy, focusing on the specific situation of bereaved siblings. Setting/participants: Eighty-six bereaved siblings (loss >1 month ago, no severe psychiatric symptoms) were randomly allocated to the intervention group (n = 47) or the waiting list control group (n = 39). Primary outcomes were symptoms of prolonged grief disorder and depression; secondary outcomes were posttraumatic stress symptoms and survivor guilt. Results: Symptoms of depression and prolonged grief disorder improved significantly in the intention-to-treat analyses from pre-to post-measurement compared with the control group (g(Depression) = -0.62, g(Grief) = 0.33). In the intervention group, all primary and secondary outcomes decreased significantly from baseline to 12-month follow-up (gs = -0.38 to -1.04). A significant clinical change could be found for depression (34%) compared to the waitlist control group (10%). Conclusions: Bereaved siblings profited from this brief internet-based writing intervention in the short- and long-term. However, future research, such as dismantling studies, may help to further optimize the benefits of an intervention aimed at bereaved siblings.

A comparison of their motives for teaching, their well-being, and their intention to stay in the profession JF - Teaching and teacher education N2 - This study investigates alternatively certified (AC) teachers' motives for teaching, their well-being, and their intention to stay in the profession. We conducted multivariate covariance analyses using a largescale dataset of 446 traditionally certified (TC) teachers and 143 AC teachers at secondary schools in Germany. Findings show that AC teachers reported more frequently than TC teachers that they chose teaching due to social influences and because of more time for their family. Furthermore, AC teachers report significantly higher enthusiasm for teaching. No differences were found regarding emotional exhaustion or the intention to stay in the profession.

Contemporary adult education research shows that beliefs and memories from one's school years have an impact on the motivation to pursue further education in working life. However, almost no longitudinal research exists that investigates the long-term forces behind adults' motivation to educate themselves. Hence, the present study examined whether students' learning-related behaviour, cognitions and emotions that developed in their school years are related to the subjective value they place on further education, their expectations of success in solving further learning tasks, and thus the likelihood of participating in further education. Corresponding structural equation analyses on data from the German panel study LifE (n = 1,110) revealed that the learning behaviour, ability self-concept and test anxiety at the age of 12, along with their individual change between the ages of 12 and 16, are associated in different ways with the attainment value and subjective costs placed on further education and expectations of success at the age of 35. In contrast, no influence of youth characteristics on the likelihood of participating in further education could be found. The findings indicate that especially the development of learning-related cognitions and emotions in secondary school is sustainably related to the individual's success expectancy and achievement value of further education. Long-term dependencies should be further investigated with regard to academic domains and socio-economic pathways.

With the availability of Intel Optane DC Persistent Memory, initial benchmarks evaluate the performance of real PMem hardware. However, these results apply to only a single server and it is not yet clear how workloads compare across different PMem servers. In this paper, we propose PerMA-Bench, a con.gurable benchmark framework that allows users to evaluate the bandwidth, latency, and operations per second for customizable database-related PMem access. Based on PerMA-Bench, we perform an extensive evaluation of PMem performance across four di.erent server configurations, containing both first- and second-generation Optane, with additional parameters such as DIMM power budget and number of DIMMs per server. We validate our results with existing systems and show the impact of low-level design choices. We conduct a price-performance comparison that shows while there are large differences across Optane DIMMs, PMem is generally competitive with DRAM. We discuss our findings and identify eight general and implementation-specific aspects that influence PMem performance and should be considered in future work to improve PMem-aware designs.
