Burnout and Mental Health in Swiss Vocational Students: The Moderating Role of Physical Activity 下载免费PDF全文
Markus Gerber Christin Lang Anne Karina Feldmeth Catherine Elliot Serge Brand Edith Holsboer‐Trachsler Uwe Pühse 《Journal of research on adolescence》2015,25(1):63-74
Few studies have focused on burnout among vocational students. This study examined the association between burnout and mental health among 56 Swiss vocational students (29 males, 27 females, M = 18.1, SD = 1.2 years) and tested whether recommended levels of moderate‐to‐vigorous physical activity (MVPA) attenuate this relationship. Burnout was strongly associated with increased depressive symptoms and decreased levels of life satisfaction, mental toughness, and quality of sleep. Students above recommended levels of MVPA reported lower burnout and higher mental health. No significant moderator effects were observed. Symptoms of burnout were associated with increased mental health problems. Physical activity should be promoted to prevent burnout, because nearly half of the students did not meet MVPA recommendations. 相似文献

This study explores the impact of information and communications technology (ICT) use on rural child welfare practice using a technology-in-practice framework to derive the social structures that are instantiated by rural child welfare workers (CWWs) and to examine their agency as actors. ICT use was tracked, and interviews were conducted with rural CWWs who work with children and families to gain an understanding of and describe their day-to-day ICT use at the practice level. Findings demonstrate that CWWs enact social structures along four frames: bureaucratic structure, family centricity, ICT context and information–documentation culture. In terms of agency, CWWs not only are constrained by but also exert some influence on the social structures they enact through facilities (material resources), norms and interpretive schemes. These findings have implications for how ICT can be used to facilitate the CWW–client relationship and the need in rural areas for increased infrastructure to support CWWs. 相似文献

ABSTRACT The recent increase in the number of girls involved in the juvenile justice system has resulted in increased academic and public attention. Thus far, this attention has focused on entry into the juvenile justice system rather than longer-term consequences. This research helps fill this gap by examining a sample of 700 maltreated and/or impoverished juvenile court–involved females. Competing risks models were used to control for time from juvenile-court entry to adult outcomes: criminal justice system involvement, use of public mental health or substance use services, and income maintenance use. Results indicate that there are distinct predictors associated with the different outcomes, although learning disability and adolescent parenthood were associated with higher risk of both mental health/substance use services and income maintenance. Individualized services for juvenile court–involved girls are suggested. Prospective, longitudinal research is needed to investigate intrapsychic and behavioral dynamics associated with females' young adult outcomes. 相似文献

ABSTRACTParenting interventions are efficacious in reducing child maltreatment and negative child behaviors, yet the recruitment and retention of parents, especially vulnerable parents, in such interventions can be challenging. Prior research identifies several ways to improve recruitment and retention including laying the foundation for the intervention, fostering relationships with parents, ensuring fit of the intervention with the intended population, and identifying barriers to parents’ participation. This case study presents a process of recruiting and retaining a vulnerable group of parents, specifically parenting youth aging out of the child welfare system. In addition to outlining the strategies used, lessons learned are highlighted. Parents expressed interest in the parenting intervention, experienced significant needs, negotiated great instability in their lives, and valued the social connections facilitated by the group intervention. Despite the research team following best practices and investing significant time and resources, recruitment and retention remained challenging. Implications for future work in this area are presented. 相似文献

A hierarchical production planning and scheduling system is developed that integrates planning decisions into a unified and consistent framework. A three-tiered approach is used to address long-term inventory control, short-term production planning, and daily scheduling tasks. A product grouping scheme introduces uniformity into the solution process and simplifies overall model complexity. Results of the model implementation are reported. 相似文献

Greater interdependence among workers and activities not only increases the need for internal communication, but it also imposes complications and barriers to effective information exchange. Intraorganizational communication capabilities of certain information systems can help overcome these barriers. However, the extent to which certain systems are promoted as communication tools depends largely on management's interpretation of their usefulness, which in turn may be largely dependent on operational context and managerial experience. We use a controlled experimental approach to study how these issues interact to impact managerial assessments of resource planning systems. Results show that managers value the communication capabilities of resource planning systems more so in highly task‐interdependent contexts and that these assessments are still more positive among managers with greater supervisory experience. As a result, these findings pose direct implications regarding the management support of technology use. 相似文献

The emergence of the Internet may have fundamentally altered the mechanisms underlying information exchanges between sellers and end consumers. However, little attention has been given to the impact these mechanisms have on the efficiency of supply chain operations. This paper begins to address this deficiency in the literature by evaluating supply chain transaction efficiency effects from Internet purchases by consumers. It develops and empirically tests a theoretical framework examining the role Internet purchases have in establishing transaction‐efficiency levels in product exchanges involving sellers, placed at different supply chain echelons, and consumers. The theoretical framework integrates the transaction‐cost and internet economics, inter‐organizational information systems, and supply chain management literatures. Empirical testing, via structural equation modeling, is based on archival data in the Internet music CD market. The results show that Internet‐mediated purchases by consumers allow for greater transaction efficiencies when inventory ownership is postponed farther upstream in the supply chain and supply chain echelons are disintermediated. The results also indicate that channel structure configuration, defined by the supply chains' Internet retailing echelon, moderates these transaction efficiency effects. 相似文献
