Until recently, little was documented about how functional capacity evaluations (FCEs) are used by employers and workers' compensation organizations. Such information was one focus of a comprehensive research study on FCEs carried out in southern Ontario, Canada, which involved representatives from the full range of groups involved in FCEs: referral sources, assessors, return-to-work specialists, third party payers and injured workers [1]. This paper shares findings from a cohort of injured workers undergoing FCEs, and explored how their FCE results were perceived and utilized by those receiving the reports. Based on study findings, we provide recommendations as to how FCEs should be requested, undertaken, reported and particularly applied to reduce work disability among injured workers. 相似文献

The Chinese household registration system (hukou), which divides the population into "agricultural" and "nonagricultural" sectors, may be the most important determinant of differential privileges in state socialist China, determining access to good jobs, education for one's children, housing, health care, and even the right to move to a city. Transforming one's hukou status from rural to urban is a central aspect of upward social mobility. Using data from a 1996 national probability sample, we show that education and membership in the Chinese Communist Party are the main determinants of such mobility. 相似文献

Several different analytical theories of justice are analyzed in the context of a uniform diagrammatic exposition. The diagrams make use of ordinary economic tools of analysis - production possibility frontiers and indifference curves. Additionally, numerous propositions are set forth which establish either the critical differences between alternative theories, or the conditions under which different theories yield identical results.This paper is a revised version of a lecture delivered at the University of Chicago (1976) and at the Public Choice Meetings in New Orleans (1978). 相似文献

Abstract Do outside firms come to North Carolina or, more generally, to the rural South to take advantage of the low-wage unorganized local relations of production? Do they disrupt local labor market arrangements? We use data from a survey of North Carolina employees to examine labor market and job quality differences between local and outside firms and also the organization of regional labor markets. Results, based on multiple regression models, suggest that outside firms provide higher quality jobs, mediated by organizational resources and internal firm relations of production. Urban Piedmont labor markets provide better jobs than rural labor markets, regardless of the establishment's ownership locale. Generally, uneven development predictions are supported by additive models, but challenged by additional analyses of interactions. These analyses suggest that outside firms may be undermining local relations of production in rural North Carolina. Results of this research present rural policymakers with a challenge for future economic development strategies. 相似文献

By changing the choice of a positional voting method, different election rankings can result from a fixed profile. A geometric theory is developed to explain why this occurs, to completely characterize all possible sets of rankings that can arise in this manner, to determine the number of rankings and other properties of these sets of rankings, to design profiles that cause the different conclusions, to develop elementary tools to analyze actual data, and to compare new types of social choice solutions that are based on the set of rankings admitted by a profile. A secondary theme is to indicate how results for voting theory can be obtained with (relative) ease when they are analyzed with a geometric approach.This research was supported by NSF Grant IRI-9103180. 相似文献

We use the martingale approach to study large deviations and laws of the iterated logarithm for certain multidimensional diffusion processes. The criteria for the validity of these properties are expressed in terms of averaging properties of the coefficients of the infinitesimal generator. In particular we apply our results to diffusion processes with random coefficients. 相似文献

A social welfare function satisfying Arrow's independence axiom is constant or authoritarian if it generates continuous and transitive social preferences over the space of allocations of public and private goods, and individual preferences have the classical economic properties. The social welfare function will be oligarchial if it generates continuous and quasitransitive social preferences and satisfies a weak version of the Pareto criterion in addition to the independence axiom.This work was supported by the National Sciences Foundation grant no.

This research examines the influence of situational ethics on cheating among college students. The analysis of responses from 6,096 students at thirty-one diverse schools suggests that neutralization is a significant factor in justifying the violation of institutional norms on academic honesty. Although cheating is generally seen as wrong, students identify many situations in which they feel cheating is acceptable. 相似文献
