Different strategies have been used to stimulate a return to work (RTW) among individuals suffering from long-term ailments. In Sweden a new law on "resting disability pension" permits disability pensioners to go back to work without jeopardising their benefits. In this study different variables related to RTW during 2000 by means of this legislation were identified among disability pensioners with musculoskeletal disorders. Individuals in the study group, when compared to a control group, had more often been disability pensioners for several years, had additional education, estimated their previous job to have been physically strenuous to a lesser degree, were more satisfied with the treatment at the social insurance office and had a more positive self-image. This study shows that it may be meaningful to continue/resume rehabilitation efforts and to try to motivate an individual suffering from musculoskeletal disorders to return to work even after several years as a disability pensioner.  相似文献

Postgraduate research students have a unique position in the debate on integrity in research as students and novice researchers. To assess how far policies for integrity in postgraduate research meet the needs of students as “research trainees,” we reviewed online policies for integrity in postgraduate research at nine particular Australian universities against the Australian Code for Responsible Conduct of Research (the Code) and the five core elements of exemplary academic integrity policy identified by Bretag et al. (2011 Bretag, T., Mahmud, S., Wallace, M., Walker, R., Green, M., East, J., James, C., McGowan, U. and Partridge, L. 2011. Core elements of exemplary academic integrity policy in Australian higher education. International Journal for Educational Integrity, 7: 312.  [Google Scholar]), i.e., access, approach, responsibility, detail, and support. We found inconsistency with the Code in the definition of research misconduct and a lack of adequate detail and support. Based on our analysis, previous research, and the literature, we propose a framework for policy and support for postgraduate research that encompasses a consistent and educative approach to integrity maintained across the university at all levels of scholarship and for all stakeholders.  相似文献

The paper is a speculative discussion of the relative saliency of communal rhetoric in instances of local social mobilisation. Despite several recent studies of local collective action, there remains considerable uncertainty as to when - and why - values exphasising local distinctiveness and superiority find assertion amongst groups at the community level. By detailing the activities of residents associations and organized amenity groups in one setting, I suggest that the saliency of communal imagery is closely associated with constraints facing local leaders in mobilising and sustaining their support. Where leadership interests are well established, yet must base their legitimacy in appeal to pluralistic sources of local support, the celebration of communal identity is pronounced and pervades local collective action. The declaration of communal unity then, marks the existence of elites for whom such sentiments are advantageous. This point suggests a re-examination of Coleman's earlier analysis of community conflict as revealing distinctive organisational dynamics, rapid issue elaboration and vilification between protagonist interests. I argue that these processes themselves reflect deeper patterns in local social organisation; the exigencies of local leader - follower relationships.  相似文献

This paper considers a matching model of the labor market where workers, who have private information on their quality, signal to firms that also differ in quality. Signals allow assortative matching in which the highest‐quality workers send the highest signals and are hired by the best firms. Matching is considered both when wages are rigid (nontransferable utility) and when they are fully flexible (transferable utility). In both cases, equilibrium strategies and payoffs depend on the distributions of worker and firm types. This is in contrast to separating equilibria of the standard model, which do not respond to changes in supply or demand. With sticky wages, despite incomplete information, equilibrium investment in education by low‐ability workers can be inefficiently low, and this distortion can become worse in a more competitive environment. In contrast, with flexible wages, greater competition improves efficiency.  相似文献

Reinforcement learning and stochastic fictitious play are apparent rivals as models of human learning. They embody quite different assumptions about the processing of information and optimization. This paper compares their properties and finds that they are far more similar than were thought. In particular, the expected motion of stochastic fictitious play and reinforcement learning with experimentation can both be written as a perturbed form of the evolutionary replicator dynamics. Therefore they will in many cases have the same asymptotic behavior. In particular, local stability of mixed equilibria under stochastic fictitious play implies local stability under perturbed reinforcement learning. The main identifiable difference between the two models is speed: stochastic fictitious play gives rise to faster learning.  相似文献
