Sequential classification on partially ordered sets

Summary. A general theorem on the asymptotically optimal sequential selection of experiments is presented and applied to a Bayesian classification problem when the parameter space is a finite partially ordered set. The main results include establishing conditions under which the posterior probability of the true state converges to 1 almost surely and determining optimal rates of convergence. Properties of a class of experiment selection rules are explored.     

The Changing Impact of Industry,Household Structure,and Residence on Household Weil-Being1

Abstract The changing impact of industry, household structure, and residence on household well-being during the 1980s is examined with data from the Current Population Survey for 1981–1982 and 1990–1991. Findings indicate that household well-being was greatest for those families relying on traditional higher-wage industries (high-wage manufacturing, government, mining). The well-being of families relying on higher-wage services was lower, most likely a consequence of the prevalence of marginal and low-paying jobs in the service sector. Rewards associated with employment in construction and low-wage manufacturing were not consistently greater than those associated with employment in low-wage services. While changes in the impact of industry were minor, significant changes occurred in the impact of an additional earner on economic well-being over the decade. Results indicate that increasing hardship has been experienced by vulnerable populations, such as nonmetropolitan and single-headed families, and minority households, particularly Hispanics. Implications for economic development strategies and work-related assistance programs are highlighted.     

Issues in psychotherapy with HIV-infected Latinos in New York city

This article will discuss issues important in psychotherapy with Latinos with HIV/AIDS in New York City. The various levels of oppressed group membership will be discussed as they relate to a therapeutic understanding of the mental health needs of Latinos. A case study will be used to demonstrate the clinical applications of the Model of Multiple Oppression.     

The consequences of acculturation to service delivery and research with Hispanic families

The experience of working with Hispanic children and their parents is compared with the existing professional literature. Although the literature acknowledges partially the importance of acculturation, the consequences of acculturation to service delivery and working with Hispanics as research subjects are seldom addressed. These consequences are demonstrated in four areas: as a cause of family problems, in the attitudes of Hispanics toward speaking Spanish and English, in the status of folk healers in the Hispanic community, and in attitudes toward the delivery of human services. The failure to take into account the consequences of acculturation can contribute to the further underutilization of mental health services by Hispanic families.The research described in this article was funded by a grant from the Blowitz-Ridgeway Foundation.Special thanks to Laura L.

An ethnographic study of pregnancy counseling

In-depth interviewing and participant observation were used to study how social workers influence birth mothers in the pregnancy counseling process. According to the workers (1) they have little or no influence over a birth mother's decision to keep or relinquish her baby and (2) the decision to keep or relinquish is largely dependent on the birth mother's emotional capacity to tolerate the loss of the child.     

Conventional versus Alternative Agriculture: The Paradigmatic Roots of the Debate*

Abstract Analysts have described conflict between the economically dominant industrial sector of society and the environmental movement as representing competition between two opposing worldviews or social paradigms. There appears to be a similar schism developing in agriculture. The conventional paradigm of large-scale, highly industrialized agriculture is being challenged by an increasingly vocal alternative agriculture movement which advocates major shifts toward a more “ecologically sustainable agriculture.” Some have suggested that alternative agriculture represents a fundamentally new paradigm for agriculture. This paper seeks to clarify and synthesize the core beliefs and values underlying these two approaches to agriculture into a “conventional agriculture paradigm” and an “alternative agriculture paradigm.” The writings of six major proponents of alternative agriculture are compared with those of six leading proponents of conventional agriculture to document the major components of the two agricultural paradigms. The two sets of writings reveal dramatically divergent perspectives on a wide range of agricultural issues. The competing paradigms can be synthesized into six major dimensions: 1) centralization vs. decentralization, 2) dependence vs. independence, 3) competition vs. community, 4) domination of nature vs. harmony with nature, 5) specialization vs. diversity, and 6) exploitation vs. restraint. The emerging controversy over “low-input, sustainable agriculture” (LISA) illustrates the paradigmatic gulf between alternative and conventional agriculture, as well as the pitfalls facing alternative agriculturalists as they attempt to replace conventional agriculture as the dominant paradigm.     

Covariates of length of stay in residential treatment

This study explores variables associated with length of stay in a child welfare residential treatment center. The study followed three entry cohorts (416 boys) from admission through discharge. The researchers conducted event history analyses to examine the rates of discharge over time and the covariates of length of stay. They conducted analyses by discharge destination (reunified, transferred, or ran away). The results demonstrated that mental health issues slowed down rates of discharge for youth who were reunified or transferred. For children who left by running away, age and prior substance history were associated with faster rates of exit. These results have important public policy implications for improving the application of length of stay variables in planning and treatment.
