One hundred and sixty-four elite union leaders in the United States completed a survey to assess the condition of the American
labor movement and the factors affecting it. The respondents included high-level international union and state federation
officers, central labor presidents, and 58 shop stewards. This study compares the responses of these labor officials and finds
that they have similar, negative assessments of the condition of the American labor movement. The study also finds that these
leaders agree that the most important factors affecting the labor movement are collective bargaining rights, union leadership,
union member solidarity, and the NLRB. 相似文献

We consider the assessment of outliers and influential observation in non-linear measurement error models. Residuals, leverage measures and case-deletiondiagonostics are examined. The method of local influence is also applied to the models. In particular, the perturbation of measurement error variances has been found useful in assessing the adequancy of the model assumptions. A numerical example is given to illustrate the application of the diagonostics. 相似文献

Conclusion Data systems created with one purpose inevitably have shortcomings when used for other purposes, so it is not surprising that a database compiled from informational tax returns has serious flaws when used to compile a statistical picture of the non-profit sector. The two-digit NTEE level of aggregation that is published in theAlmanac conceals many problems that appear when the IRS-based data are broken down to the three-digit level.Identification of the problems in the NTEE and in the use of the IRS data is a necessary step toward their correction. At this point, it is clear that the IRS-based numbers in theAlmanac should be regarded, at best, as rough approximations and as a starting point for additional work. My assessment of theAlmanac suggests that, at least as far as health care is concerned, the NTEE needs revision. Correcting the problems with the IRS data will be much, much more difficult.I am grateful for assistance from Steve Noga, Chris Toppe and Virginia Hodgkinson at Independent Sector. 相似文献

Efficient contracts set incentives through the assignment of rights and profit shares., Although efficient contracts have been used to explain the nature of the firm, the use of contractual rights in specific business contracts is relatively unexplored. We analyze contractual rights in franchise systems, in particular the right to add franchisees. An exclusive territory assigned to an initial franchisee is not an immutable guarantee, but rather a starting point for subsequent renegotiation in the franchise relationship. Exclusivity is therefore profitable when franchisee efforts are critical to the venture. A sample of franchise contracts reveals evidence consistent with the model's prediction. 相似文献

Abstract Consumer concerns over pesticide residues and food additives have been growing in industrialized societies, including the United States and Japan. However, little comparative research has been carried out to determine which household characteristics may be significantly associated with these heightened concerns, and whether or not the same factors are useful for understanding variation in these worries in more than one society. This paper examines food safety attitudes in Seattle, Washington, and Kobe, Japan, and discovers that while the absolute level of expressed concern is higher in Kobe, the predictive power of household characteristics in explaining attitudinal differences within countries is similar. Implications for rural areas and future research on family structures in capitalist societies are discussed. 相似文献

The Contra Costa County educational program for juveniles found guilty of driving under the influence (DUI) was evaluated. Over 600 juveniles convicted of DUI from 1983 to 1988 formed the study group for this research and of these over 100 participated in the educational program. Assessment of program participants was conducted for knowledge, attitudes and behavior. Participants demonstrated increased knowledge, stronger attitudes against driving under the influence, and less risky alcohol and automobile related behaviors. County juvenile records analyzed by the logit procedure showed that class participants had a significantly lower number of repeat offenses compared to non-program participants that could not be explained by race, offense severity, age or gender. 相似文献
