We study subgame perfect implementation through perfect information mechanisms in economic environments. We assume that worst bundles exist for each agent and can be assigned to them independently of the bundle assigned to at least one other agent. We restrict our attention to allocation rules that are anonymous, efficient on their own range, single-valued in welfare, and that induce agents' participation. We define a class of mechanisms, which satisfy properties of minimal path length and finiteness of message dimensions. We characterize the class of allocation rules which can be implemented through those mechanisms.I would like to thank Bhaskar Dutta, Louis Gevers, Matthew Jackson, Ozgur Kibris, Hervé Moulin and Arunava Sen for stimulating discussions, seminar participants at Université de Montréal (the Axiomatic Theory of Resource Allocation meeting, May 1996), Universitat Autonoma de Barcelona, Universitad Carlos III de Madrid and Université de Paris Dauphine for their comments, and Frédéric Gaspart, Tarik Kara, James Schummer, William Thomson and an anonymous referee for extremely useful comments and suggestions on earlier versions. 相似文献

This paper studies how consumers' reported practices related to food, energy use in housing, daily mobility, and tourism are combined and structured. Social practice theories are the main theoretical framework of this research. Data are drawn from a sensitisation campaign run by the WWF-Belgium and the methods developed to attempt to translate the theoretical focus to practices. Results show that both the low number of ‘green’ practices reported and the multiplicity of combinations of practices indicate a rather important compartmentalisation of ‘green’ practices and seem to refute the hypothesis of vast domino effects in these four different areas. In addition, a wider openness to information on environmentally friendlier practices is associated with a larger number of such practices, which raises questions about the design of such campaigns. Finally, there is no conventionalised way of linking practices and commitments taken by the respondents to reduce their environmental impact. A few policy recommendations are derived for sensitisation campaigns that often assume domino effects between ‘green’ practices, and for tools dealing with personal carbon awareness. 相似文献

In response to growing concerns with explaining how work and family interfere with each other and with statistical approaches that do not capture the way in which predictors interact, this study tested statistical interactions involving personal and social resources of 410 full‐time employed women and men. The results indicate that self‐efficacy is a strong predictor of family interfering with work (FIW) and work interfering with family (WIF). Gender moderates the relation between supervisor support and WIF moderates the impact of efficacy beliefs and instrumental support at home on FIW. Specifically, while supervisor support is negatively related to WIF in women and men, high levels of support more strongly affected men's perceptions of WIF. In low self‐efficacy men, high levels of support at home improved their perceptions of FIW but these perceptions worsened in women. These findings contrast with earlier research that focus predominantly on the predictive value of structural demands (for example, the number of hours worked per week and family size). This study shows that gender plays a critical yet intricate role as a predictor of the successful management of work and family roles: it is not gender per se but its interaction with personal and social variables that informs us about differences in the experience of employed parents. 相似文献

Bedsores (ulcers) are caused by multiple factors which include, but are not limited to; pressure, shear force, friction, temperature, age and medication. Specialised support services, such as specialised mattresses, sheepskin coverings etc., are thought to decrease or relieve pressure, resulting in a lowering of pressure ulcer incidence [3]. The primary aim of this study was to compare the upper/central body pressure distribution between normal lying in a hospital bed versus the use of a pressure redistribution belt. The study involved 16 healthy voluntary subjects lying on a hospital bed with and without wearing the belt. Results showed that the use of a pressure redistribution belt results in reduced pressure peaks and prevents the pressure from increasing over time. 相似文献

Work-related musculoskeletal disorders (WRMD) are the result of the combination of different risk factors. They are very common among computer workers, mainly when neck and upper limbs are considered. Forty-two office workers from a public university participated in this study. They were divided into two groups: Symptomatic Subjects (SS, n=20) and Asymptomatic Subjects (AS, n=22), according to the Nordic Musculoskeletal Questionnaire (NMQ). Psychosocial indicators were assessed using the Job Content Questionnaire (JCQ) and Utrecht Work Engagement Scale (UWES). Workplaces were evaluated according to the Ergonomic Workplace Analysis (EWA), proposed by the Finnish Institute of Occupational Health. The NMQ showed higher weekly prevalence of complaints on neck, shoulders and wrist/hands (p=0.00) among SS. The annual prevalence of symptoms on wrist/hands was also higher among SS (p=0.02). The JCQ did not show any difference between groups (p>0.05). Higher proportion of servers with 'high level' of engagement, dedication and absorption, according to UWES, was identified among SS (p<0.01). EWA showed worse scores for 'Work Site', 'Job Content' and 'Repetitiveness of the Work' among SS (p<0.05). Servers are exposed to physical and psychosocial risk factors that can contribute to the development of WRMD. Work conditions need to be change in order to improve musculoskeletal health. 相似文献
