Voices of Children from Around the Globe; An International Analysis of Children's Issues at Child Helplines

Child helplines around the world are an important mental health resource for many children. In this study, an international database was analysed with a total of 25 million registered calls at a total of 111 helplines affiliated with Child Helpline International. The research was aimed at discovering if there are differences between the reasons for calling of children from different parts of the world, and if shifts in the studied 10‐year period can be observed. The data show that all child helplines are contacted by young people seek support with questions concerning abuse, sexual matters and school issues. The results from a mixed model also show significant differences in the reasons for calling between Africa, Asia, Europe, Latin America, North America, the Pacific region and the region Middle East and North Africa. Child helplines in Africa and other developing parts of the world received many calls related to safety and health (e.g. HIV/AIDS, commercial exploitation), whereas children and young people from Europe, North America and the Pacific more often discussed social and psychosocial issues with the helpline (e.g. mental health, peer and family relations). The reasons for calling were relatively stable for the studied period.     

Constraining Is Enabling? Exploring the Influence of National Context on Civil Society Strength

This article analyses the influence of national context on civil society strength based on four key dimensions: level of democracy, political stability, rule of law and economic development. Whereas existing studies mainly focus on Western and post-communist countries, we explicitly include developing countries in our analysis. We use associational membership as proxy for civil society strength and include data of 53 countries. Rule of law, economic development and (to a lesser extent) political stability emerge from our multilevel regression models as the main factors affecting civil society membership. Unlike previous studies, we show that these relations are quadratic instead of linear. This means that where existing theories predict a drop in memberships in developing countries, we find a rise. In other words, harsh conditions actually strengthen civil society in terms of membership levels. We argue that this could be the case because reasons for CSO membership are essentially different in the developed and in the developing world. Contrary to theoretical assumptions, democratic rights do not appear critically important for civil society membership.     

Lot Splitting in Unbalanced Production Systems*

This research investigates the impact of lot splitting in unbalanced production systems, under a variety of experimental conditions. Scheduling policies specifically designed for use in the presence of a long-term bottleneck, a condition frequently encountered in practice, are developed and tested. Results indicate that when steps are taken at nonbottleneck work centers to capitalize on capacity imbalances through increasing the number of setups and, hence, the variety of products produced, shop effectiveness is improved. The results also indicate that scheduling policies that tend to increase the size of the average process batch retard the overlapping of operations, which is critical to the success of the lot-splitting methodology in reducing flow time. Finally, it is shown that increasing capacity at nonbottleneck work centers along with implementation of effectiveness-oriented scheduling polices leads to improved shop performance.     

The longitudinal development of students' well-being in adolescence: The role of perceived teacher autonomy support

Although a decline in adolescents' well-being has repeatedly been reported, longitudinal evidence for this development is rare and time-varying factors like teacher autonomy support that could be associated with this trend have sparsely been investigated. Therefore, the present study examined how the temporal development of perceived autonomy support from their German language arts teachers is related to changes in four different facets of students' well-being. Longitudinal data from 3446 adolescents from Germany (N_Schools = 178) on five measurement points (Grades 5–9) were analyzed using latent growth curve models. Satisfaction with school, enjoyment of school, and self-rated health decreased over time, while social integration remained stable. Perceived teacher autonomy support also declined between Grades 5 and 9. Furthermore, baseline levels of perceived teacher autonomy support and facets of well-being were positively related. Finally and most importantly, our results indicated that changes in perceived teacher autonomy support were positively associated with the development of satisfaction with school, enjoyment of school, and self-rated health, but not social integration. The findings suggest that perceived teacher autonomy support plays an important role in the development of students' well-being in adolescence.     

An Evaluation of Flexible Workday Policies in Job Shops*

Job shops have long faced pressures for improvement in a challenging and volatile environment. Today's trends of global competition and shortening of product life cycles suggest that both the challenges and the intensity of market volatility will only increase. Consequently, the study of tactics for maximizing the flexibility and responsiveness of a job shop is important. Indeed, there is a significant body of literature that has produced guidelines on when and how to deploy tactics such as alternate routings for jobs and transfers of cross‐trained workers between machines. In this paper we consider a different tactic by adjusting the length of workdays. Hours in excess of a 40‐hour week are exchanged for compensatory time off at time and a half, and the total amount of accrued compensatory time is limited to no more than 160 hours in accordance with pending legislation. We propose several simple flexible workday policies that are based on an input/output control approach and investigate their performance in a simulated job shop. We find significant gains in performance over a fixed schedule of eight hours per day. Our results also provide insights into the selection of policy parameters.
