Using an interview survey of manufacturing establishments that provide 10 years of retrospective data on labor practices, we investigate factors associated with the adoption and termination of employee involvement programs and the relation between these and other human resource policies. In the period studied, more firms introduced than terminated such programs but a sufficiently large number chose to eliminate such programs to indicate that employee involvement does not fit in all business settings. Our results show that business strategy and the use of other complementary human resource policies affect the dynamics of employee involvement use in US manufacturing establishments. 相似文献

Central to the activities of any industry is the modernization of its assets. This paper describes the application of statistical methods to the asset management plan of a large water company. A model for the underground assets is given in detail, and the extensive computations required are illustrated. A Bayesian model shows the consequences of various policy options and provides realistic measures of the uncertainty connected with them. 相似文献

Objective. This study examines how the odds of a black renter becoming a homeowner changed during the 1990s, considering significant policy changes aimed at dismantling discriminatory barriers to nonwhite homeownership during that time period and various housing‐market characteristics, including the level of residential segregation. Methods. This study uses geocoded data from the Panel Study of Income Dynamics and from the 1990 and 2000 Censuses to estimate an event‐history model of transition into homeownership for black Americans. Results. The results of this study suggest that blacks benefited from the changing home‐lending environment and were more likely to become homeowners during the 1990s. These improvements appear to be both absolute and relative to whites. This implies that the policy changes had some success. Nevertheless, blacks were significantly less likely to become homeowners during the study period—even after controlling for a variety of factors known to be associated with homeownership—suggesting that further reforms may be necessary to eradicate disparities in access to homeownership between whites and blacks. The analysis also shows that blacks residing in metro areas with the highest levels of racial isolation were significantly more likely to become homeowners than blacks residing in metro areas with the lowest levels of isolation. Conclusion. The study results show that the policy reforms of the 1990s likely had a salutary effect on black homeownership. The results also suggest that residential segregation matters to black homeownership in complex ways. 相似文献

This paper tackles the practical application of statistical tools. Chemical development is a rich area for collaboration between statisticians and chemists, but most statisticians encounter difficulties in promoting the tools to this client group. This paper, presented from a chemist's perspective, is intended to help bridge the gap between the two professions. The paper explores differences in uptake and attitudes towards adopting these techniques and suggests what has hindered or helped the process of effective application of experimental design.

This is an examination of a set of dimensional conceptions of graphs that might be used to shed light on the structural complexity of social networks. Problems of characterizing various conceptions are explored and computational methods are reviewed. 相似文献

In this paper, we focus on models for recovery data from birds ringed as young. In some cases, it is important to be able to include in these models a degree of age variation in the reporting probability. For certain models this has been found, empirically, to result in completely flat likelihood surfaces, due to parameter redundancy. These models cannot then be fitted to the data, to produce unique parameter estimates. However, empirical evidence also exists that other models with such age variation can be fitted to data by maximum likelihood. Using the approach of Catchpole and Morgan (1996b), we can now identify which models in this area are parameter-redundant, and which are not. Models which are not parameter-redundant may still perform poorly in practice, and this is investigated through examples, involving both real and simulated data. The Akaike Information Criterion is found to select inappropriate models in a number of instances. The paper ends with guidelines for fitting models to data from birds ringed as young, when age dependence is expected in the reporting probability. 相似文献

A professional critically examines her practices towards parents whilst an educational psychologist. Aspects of the power relationship are explored, including acting as a friend, the trappings of professionalism, privacy and confidentiality, interprofessional trust, and the provision of services. A tentative conclusion reached is that these create dilemmas which are part of the workings of the system within which the educational psychologist works, and that professional survival is the underlying motive. 相似文献
