Bridge employment and job stopping: evidence from the Harris/Commonwealth Fund Survey

This article analyzes a 1989 Louis Harris and Associates survey designed to elicit information on the employment histories and job-stopping behavior of men and women who then were approaching or had recently reached retirement age. The results indicate that retirement often occurs gradually and includes a substantial period of "bridge employment." Most bridge jobholders work full-time, by choice, and report high levels of job enjoyment. Occupational mobility occurring late in life typically involves upward movement, although the pattern of change is quite different when it takes place outside, rather than within, the longest job. The principal concern identified in this article is the limited ability of some groups of workers (nonwhites, females, the less educated, and those in poorly compensated occupations) to either retain longest jobs or to obtain acceptable bridge employment. Health problems also frequently lead to early departures from the labor force.     

Environmental hazards and the health status of women and children in a riverine community in Nigeria: Nikrowa in Edo State

Nikrowa is a riverine village located in Ovia North-East Local Government Area of Edo State. This paper examines the relationship between the environment and the health status of women and children in the village. Data used in this essay were obtained mainly in focus groups from a study of women and health service utilization in Nikrowa. Women in Nikrowa farm, fish, collect water and firewood, and process and prepare food. They also bear many children. Their hard physical labor causes them to suffer continuous body aches and pains. Environment-related illnesses such as malaria, measles, dysentery, and diarrhea are prevalent among children. The geographical isolation of Nikrowa limits access to modern health care facilities, so traditional therapies are used to treat prevailing illnesses. It is suggested that women have access to fertilizers in order to improve soil fertility and agricultural yields. Fuelwood and adequate and safe water supplies should be made readily available to women. Moreover, access roads to rural areas should be improved to facilitate transport to modern health care facilities, and rural primary health care facilities should be helped to provide efficient services by providing trained staff and ensuring regular supplies of drugs.     

Economic integration and labor flows: stage migration in farm labor markets in Mexico and the United States

"This article examines the probable effects of the North American Free Trade Agreement (NAFTA) on migration from Mexico to the United States, disputing the view that expansion of jobs in Mexico could rapidly reduce undocumented migration. To the extent that NAFTA causes Mexican export agriculture to expand, migration to the United States will increase rather than decrease in the short run. Data collected in both California and the Mexican State of Baja California show that indigenous migrants from southern Mexico typically first undertake internal migration, which lowers the costs and risks of U.S. migration. Two features of employment in export agriculture were found to be specially significant in lowering the costs of U.S. migration: first, working in export agriculture exposes migrants to more diverse social networks and information about U.S. migration; second, agro-export employment in northern Mexico provides stable employment, albeit low-wage employment, for some members of the family close to the border (especially women and children) while allowing other members of the family to assume the risks of U.S. migration."     

Implementing partial least squares

Partial least squares (PLS) regression has been proposed as an alternative regression technique to more traditional approaches such as principal components regression and ridge regression. A number of algorithms have appeared in the literature which have been shown to be equivalent. Someone wishing to implement PLS regression in a programming language or within a statistical package must choose which algorithm to use. We investigate the implementation of univariate PLS algorithms within FORTRAN and the Matlab (1993) and Splus (1992) environments, comparing theoretical measures of execution speed based on flop counts with their observed execution times. We also comment on the ease with which the algorithms may be implemented in the different environments. Finally, we investigate the merits of using the orthogonal invariance of PLS regression to improve the algorithms.     

Applied sociology? Even musicians give concerts

Applied sociology is basically what sociologists do for nonsociologists and sometimes for themselves. Applied sociology includes the teaching of sociology as one of the liberating arts and sciences. It also involves the practice of sociology outside academia in the public and private sectors. Either way, applied sociology needs support groups, and state sociological associations need useful things to do beyond their traditional interests in academic teaching and research. Professional sociological associations, and especially those that serve at the local, state level, can become important support groups for applied sociology. This article suggests five types of applied sociology projects appropriate for state associations. These are volunteering applied sociology; doing applied sociology through consulting; making the value of sociological applications more visible; identifying applied sociology jobs for our baccalaureate, master's, and doctoral graduates; and helping to improve the socioeconomic outlook for our academic colleagues and, in turn, ourselves. State associations provide an organizational base, proximate members, and local opportunities for applying sociology. Ron Wimberley, teaches sociological research methods and does research on the southern Black Belt and other topics. He also attempts applied sociology through volunteer work, consulting, and occasional leaves from his university position. Catherine Harris of Wake Forest University is appreciated for suggesting the topic. The author is responsible for the views expressed in the article.     

Implications of ERISA for health benefits and the number of self-funded ERISA plans

This Issue Brief provides an overview of the issues relating to the Employee Retirement Income Security Act of 1974 (ERISA) and health benefit plans, the major case law relating to ERISA and health plans, and the implications of the preemption of state regulations for health plan sponsors and participants. It also presents the latest data on the number of health plan participants in self-funded ERISA plans. Finally, it presents a summary of current legislative proposals that would attempt to amend ERISA. Under the framework ERISA established for employee benefit plans, the regulation of employment-based health benefit plans has evolved into a two-tiered system in which both federal and state laws play important roles. The Supreme Court has interpreted ERISA's "savings" and "deemer" clauses to mean that insured plans are subject to regulations directly at the federal level and indirectly at the state level, while self-funded plans are regulated exclusively at the federal level. The ERISA statute and the courts' interpretations of the Act have created a sharp controversy over how employee health benefit plans are provided and administered, with state regulators and consumer advocates on one side of the debate and plan sponsors (e.g., employers and unions) on the other. State regulators and consumer advocates tend to favor more regulation, and in many instances greater regulation at the state level, which they argue would provide more protections for consumers. However, employers and unions (or any plan sponsors) think ERISA preemption is very important to their ability to provide innovative and cost-effective health benefits for their employees, and assert that ERISA's present structure should be preserved. The U.S. General Accounting Office (GAO) found that 44 million individuals (39 percent of those in ERISA plans) were enrolled in self-funded ERISA plans in 1993, up from 39 million (33 percent of those in ERISA plans) in 1989. The Employee Benefit Research Institute (EBRI), using the same methodology as GAO with 1995 data, estimated that 48 million individuals (39 percent of those in ERISA plans) were enrolled in self-funded ERISA plans in 1995. When policymakers look to amend ERISA, they should consider whether the change to ERISA will produce a higher level of quality for consumers than is being provided under the present system and will continue to do so in the future. Policymakers must also decide whether quality of care is better enhanced by health plans' greater exposure to liability or by market forces. If policymakers decide that increased exposure to liability is the route to go, will consumers be able to enjoy any potential improvement in quality or will more individuals end up uninsured because of increased costs and not be able to get any care regardless of the quality?
