The aim is to analyse the implementation of a case manager-model in rural Sweden. A sample of 15 case management teams was selected. Written materials were collected and interviews on location were carried out. Results: rural case managers design their work methods themselves, which entail several deviations from the national policy guidelines in this field. The case management boards have a low capacity to direct and manage the activities of the case managers. Consequently, case managers develop into ‘welfare entrepreneurs’. One salient risk is that teams become isolated from the surrounding welfare system. In conclusion, the Swedish version of case management in rural areas is a result of local processes of adaptation and negotiation that result in services that differ from those envisaged in national policy guidelines.  相似文献

This investigation approaches the levels and the predictors of loneliness among migrant youths from returned migrant families from France to Portugal. Three research questions guided the study: (1) Does loneliness of migrant youths differ from those who have never migrated? (2) Are migrant youths’ re-acculturation factors related to their loneliness? (3) Is the adaptation of migrant youths linked to their loneliness? The answer to these questions is important to improve migrant youths’ re-acculturation experiences and their adaptation. The sample included 222 youths from returned migrant families from France. Participants completed the brief Portuguese version of the Revised UCLA Loneliness Scale (ULS-6), in addition to measures of re-acculturation and adaptation. A control group comprised of 211 Portuguese adolescents who have never migrated was also involved in the investigation. Youths from returned migrant families showed lower levels of loneliness than their native Portuguese counterparts who have never migrated. Demographic, re-acculturation, and adaptation factors were significantly related to adolescents’ loneliness. Major predictors of loneliness were age at return, contacts with peers without migratory experience, perceived discrimination, stressful adaptation experience, and satisfaction with life.  相似文献

Participatory decision making seems to be the new development paradigm in international cooperation. It is still a long way, however, to achieve the objectives that are formulated by the international development actors. Non-state actors are only limitedly involved in the policy decision-making. In this paper, we argue that when these actors take their commitment towards civil society organisations serious, more efforts can be made to improve the available data and indicators on these actors’ policy involvement. We discuss the most important existing databases on civil society’s policy participation and find that only limited data is available. This means that there exist opportunities to: first, extend and refine the existing data and indicators on the policy involvement of these actors; and second, include these data and indicators in the assessment exercises of international development organisations. In addition, we observe a difference, between the available data on the traditional social partners and the new civil society organisations. Therefore, we argue that more research, data collection and the elaboration of indices, on the various policy involvement mechanisms of new civil society organisations would be a welcome contribution to the field. Furthermore the opportunity exists to examine the relation with other governance variables, such as accountability, transparency and rule of law.

The bold lines that have separated the application of specific production planning and control techniques to specific production systems are being blurred by continuous advances in production technologies and innovative operational procedures. Oral communication among dispatchers and production units has given way to electronic communication between production planners and these units by continuous progress in information technologies. Current production literature alludes to the idea that, collectively, these advances have paved the way for application of Just‐In‐Time (JIT) production concepts, which were originally developed for mass production systems, in intermittent production systems. But this literature does not actually consider the possibility. This article presents a modification to JIT procedures to make them more suitable for jumbled‐flow shops. This article suggests providing real‐time information about net‐requirements for each product to each work center operator for setting production priorities at each work center. Simulation experiments conducted for this study show that using Net‐Requirements in JIT (NERJIT) reduces customer wait time by 45–60% while reducing inventory slightly. The analysis of work centers’ input and output stock‐point inventories shows that using the information about net‐requirements results in production of items that are in current demand. NERJIT results in smaller input stock‐point inventory and availability of products with higher priority in the output stock‐points of work centers.  相似文献
