Validating Work Discrimination and Coping Strategy Models for Sexual Minorities

The purpose of this study was to validate and expand on Y. B. Chung's (2001) models of work discrimination and coping strategies among lesbian, gay, and bisexual persons. In semistructured individual interviews, 17 lesbians and gay men reported 35 discrimination incidents and their related coping strategies. Responses were coded based on Chung's models. Results supported the validity of the Work Discrimination model and two coping strategy models (Vocational Choice and Identity Management). The Discrimination Management coping strategy model was expanded. Implications for practice and research are discussed.     

Alternative Methods for Computing the Sensitivity of Complex Surveillance Systems

Stochastic scenario trees are a new and popular method by which surveillance systems can be analyzed to demonstrate freedom from pests and disease. For multiple component systems—such as a combination of a serological survey and systematically collected observations—it can be difficult to represent the complete system in a tree because many branches are required to represent complex conditional relationships. Here we show that many of the branches of some scenario trees have identical outcomes and are therefore redundant. We demonstrate how to prune branches and derive compact representations of scenario trees using matrix algebra and Bayesian belief networks. The Bayesian network representation is particularly useful for calculation and exposition. It therefore provides a firm basis for arguing disease freedom in international forums.     

Causes of Disaster: Sloppy Management

The loss of control associated with accidents and disasters can have severe negative consequences for the organizations involved. Some disasters are caused by inadequacies of management, or by unprofessional behaviour but others arise when disaster preconditions are generated as a result of the normal functioning of larger managerial and technical systems. During the incubation period preceding a major incident, therefore, two levels of correction need to be considered to avoid disasters. ‘Sloppy management’ of various kinds can be tackled by establishing, strengthening and asserting appropriate forms of management control. The system properties which constitute disaster preconditions are less immediately accessible to management control. At both levels managers in pursuit of high reliability should expect to have to make a range of trade-offs.     

The Internet's impact on policy evaluation: information compression and credibility

As with all media, the Internet structures and frames information, rewarding some information search and decision behaviors while punishing others and, thereby, strongly influences evaluation research results and possibilities. Now that the Internet is for many evaluators the information medium of choice, the impacts of the medium on evaluation deserve careful attention. The objective of this article is to lay groundwork for a theory of the impact of the Internet on evaluation and policy analysis. Questions addressed include the following: (a) What is the impact of the Internet on the evaluator's professional role, work norms, and work habits? (b) Does the use of the Internet affect who is an evaluator or the meaning of professional evaluation? and (c) How does evaluation via Internet affect the technical quality and credibility of evaluation? A key thesis is that the Internet compresses information in the sense that it is not always easy to distinguish among information resources and, especially, the authority of the information provider and the nature of the knowledge warrant. On one hand, the Internet's information compression seems to hold potential for the democratization of evaluation. On the other hand, the diminished ability to make quality distinctions about evaluation-relevant information may undercut the legitimacy of evaluation.     

Eating dysfunctions in college women: the roles of depression and attachment to fathers

The authors examined the roles of depression and attachment to fathers in college women's eating dysfunctions. Three-hundred six undergraduate women completed (1) a diagnostic measure of eating dysfunctions that categorized them as asymptomatic, symptomatic but not eating disordered, or eating disordered; (2) 3 dimensional measures of attachment to fathers; and (3) a dimensional measure of depression. Depression was directly related to severity of participants' eating dysfunction; the eating-disordered group had scores consistent with clinical depression. After controlling for depression, 3 facets of attachment to fathers significantly differentiated the 3 groups.     

Jacob Mincer,Experience and the Distribution of Earnings

This paper reviews Jacob Mincer's contributions to the analyses of earnings and the distribution of earnings through his pioneering focus on labor market experience or on-the-job training. It begins with a brief discussion of the theoretical literature on the distribution of earnings in the pre-Mincer period, and then discusses his analysis of human capital and earnings developed in his 1957 doctoral dissertation and 1958 Journal of Political Economy (JPE) article. Further analyses of on-the-job training, and in particular estimates of the rate of return from on-the-job training, are presented in his 1962 JPE paper. The synergy between Mincer and Becker during the 1960s is discussed, as is the development of the schooling-earnings function by Gary S. Becker and Barry R. Chiswick (1966). Jacob Mincer extended this relationship by incorporating experience to form the human capital earnings function in his Schooling, Experience and Earnings (1974). Subsequent modifications, extensions, tests of robustness and the wide applicability of the human capital earnings function are presented.     

Multivariate distributions defined in terms of contours

The paper deals with the problem of using contours as the basis for defining probability distributions. First, the most general probability densities with given contours are obtained and the particular cases of circular and elliptical contours are dealt with. It is shown that the so-called elliptically contoured distributions do not include all possible cases. Next, the case of contours defined by polar coordinates is analyzed including its simulation and parameter estimation. Finally, the case of cumulative distribution functions with given contours is discussed. Several examples are used for illustrative purposes.
