We argue that earlier characterizations of clients are inadequate in considering the complexities of organizational-client relations. Some writers assume that client alienation is an inevitable outcome of certain types of bureaucratic structures (e.g., welfare). We show that in the face of large service organizations, some clients fail to experience significant amounts of alienation by forcing organizations to vacate traditional bureaucratic forms and processes. The lack of alienation is accounted for by clients' expertise, political organization, and their access to bureaucracy. 相似文献

Vitaro F Wanner B Ladouceur R Brendgen M Tremblay RE 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》2004,20(1):47-69
This study aimed at empirically identifying groups of adolescents with distinct longitudinal trajectories of gambling involvement and validating these groups by comparing them with respect to correlates. 903 low SES boys were followed annually from age 11 to 16 years. Three groups were found: an early-onset high-level chronic group, a late-onset high-level group, and a low gambler group. The Chronic group and the Low group consistently differed on teacher-rated inhibition (i.e., anxiety) during childhood and early adolescence. They also differed on concurrent teacher and self ratings of disinhibition (i.e., impulsivity), while the Late Onset group appeared to lie in between these groups. Compared to the Low group, both high groups subsequently had elevated scores on later gambling related problems. 相似文献

It may be difficult or impossible to make a reliable empirical investigation of an unknown network of interpersonal choices or contacts if these are in some respect sensitive for the individuals involved. We consider how choice data given anonymously can be used to reveal various features of the network. Using tools from statistical decision theory and information theory we can determine risks and capacities of disclosing choice data, the graph structure of choice data and its numbers of loops and mutuals. We give some general results, illustrate the combinatorial complexity of the problem and comment upon the computational difficulties. 相似文献

Frank M. Andrews 《Social indicators research》1974,1(3):279-299
Modern societies in both developing and developed countries have real and legitimate concerns about the enhancement, maintenance, and redistribution of individual well-being. Indicators of perceived well-being provide direct measures of what societies are trying to achieve, permit cross-sector comparisons, can indicate the adequacy of coverage of ‘objective’ indicators, and can contribute to social policy making. in both the long and short run. Some commentators, however, have suggested perceptual indicators suffer from methodological weaknesses associated with their validity, interpretability, completeness, and utility. Each of these possible weaknesses is addressed in some detail. New research evidence and certain philosophical perspectives are presented, and it is concluded that none of these presumed weaknesses is sufficient to invalidate the development and use of perceptual indicators. Suggestions are made concerning methodological research needed to support the development of indicators of perceived well-being. It is noted that the materials and results developed in the author's research on Americans' perceptions of life quality may be useful for suggesting approaches to the development of indicators of perceived life quality relevant to other cultures. 相似文献

Influence of Safety Measures on the Risks of Transporting Dangerous Goods Through Road Tunnels 总被引:1,自引:0,他引:1
Quantitative risk assessment (QRA) models are used to estimate the risks of transporting dangerous goods and to assess the merits of introducing alternative risk reduction measures for different transportation scenarios and assumptions. A comprehensive QRA model recently was developed in Europe for application to road tunnels. This model can assess the merits of a limited number of "native safety measures." In this article, we introduce a procedure for extending its scope to include the treatment of a number of important "nonnative safety measures" of interest to tunnel operators and decisionmakers. Nonnative safety measures were not included in the original model specification. The suggested procedure makes use of expert judgment and Monte Carlo simulation methods to model uncertainty in the revised risk estimates. The results of a case study application are presented that involve the risks of transporting a given volume of flammable liquid through a 10-km road tunnel. 相似文献

In this paper, we propose the incremental group testing model for the gap closing problem, which assumes that we can tell the difference between the outcome of testing a subset S, and the outcome of testing S {x}. We also give improvements over currently best results in literature for some other models. 相似文献

Perceived Risks from Radiation and Nuclear Testing Near Semipalatinsk, Kazakhstan: A Comparison Between Physicians, Scientists, and the Public 总被引:2,自引:0,他引:2
Determining the difference in perception of risk between experts, or more educated professionals, and laypeople is important so that a potential hazard can be effectively communicated to the public. Many surveys have been conducted to better understand the difference between expert and public opinions, and often laypeople exhibit higher perceptions of risk to hazards in comparison to experts. This is especially true when health risk is due to radiation, nuclear power, and nuclear waste. This article focuses on one section of a risk perception survey given to two groups of individuals with a more specialized education (scientists and physicians) and laypeople (villagers) in the Semipalatinsk region of Kazakhstan. All of these groups live near the former Soviet nuclear test site. Originally, it was expected that the scientists and physicians would have similar perceptions of radiation risk, while the public perceptions would be higher, but this was not always the case. For example, when perceptions of risk pertain to the health impacts of nuclear testing or the dose-response nature of radiation exposure, the physicians tend to agree with the laypeople, not the scientists. The villagers are always the most risk-averse group, followed by the physicians and then the scientists. These differences are likely due to different frames of reference for each of the populations. 相似文献
