This investigation assesses the relationships between racial threat and partisan dominance in state legislatures with tests of interactive hypotheses. The findings show that historically contingent expectations derived from racial threat theory, Republican law and order campaign appeals, and fundamentalist strength account for Republican strength in the legislatures. Two-way fixed-effects estimates based on pooled time-series analyses of 799 state-years in the post-civil rights era show that the percentage of Republicans in the state legislatures grew after increases in African American presence and the violent crime rates. The combined effects of a growth in African American and fundamentalist populations also account for increased Republican seats in these bodies. Statements by Republican campaign officials on how they deliberately used mass resentments against minorities to gain votes provide evidence about the intervening links between minority threat, the menace posed by high violent crime rates, and increased Republican strength in the state legislatures.  相似文献

The state controls many matters of conflict between labor and management. This study attempts to identify the social conditions that lead to laws which favor either side in their ongoing struggle for influence. Using a cross-sectional ecological design I found that political systems with more blacks were least likely to have public policies in the interest of the working class. Other relevant factors which had less consistent effects were the type of enterprise and the level of resources in an area. Generally, the results are consistent with theories that racial antagonisms undermine the political efforts of workers.  相似文献

The pattern of changes in the Extended Learning Curves representing the performance of 114 assembly workers in an electronics firm is examined in terms of changes in productivity drift over long periods of time. It is shown that 2 types of discontinuities can occur. The first consists of a temporary levelling off in productivity followed by a recovery to new higher levels of productivity; the second has a sustained period of negative productivity drift. A number of work facets are statistically tested as possible causes of these patterns of productivity drift, but, the only significant relationship (at P ≤ 0.05 level) is with length of service in job. Some evidence is presented to show that conventional work measurement methods are not effective in terms of assessing the true work output of experienced workers since such workers are able to beat the system by claiming those allowances which are most difficult to cross-check.  相似文献

ABSTRACT

In 2008, there were more than a million persons with HIV/AIDS in the United States. The CDC (2007) estimates that 15% of persons with HIV/AIDS are over age 50. At greater risk are women of color. Most intervention efforts have focused on intrapersonal aspects of an individual and his or her sexual-risk behaviors, with little or no attention directed toward interpersonal and socioenvironmental considerations of risk and prevention. This paper considers the limitations of current national policies relating to HIV prevention in minority populations, especially among midlife and older women of color. In particular, this paper examines risk and prevention policies in light of ecological perspectives, social capital, and dialogical theories.  相似文献

We strongly reject the full-insurance hypothesis, using testing variables that are not decision variables for the households under investigation. We find that households are not insured against changes in the unemployment rate associated with the household head's occupational category. Using this exogenous information, we also investigate the appropriateness of exogeneity assumptions on idiosyncratic variables that have been used as testing variables in the full-insurance literature. It is shown that several exogeneity assumptions made in the existing literature are potentially problematic.  相似文献

Abstract

Gradually, developments in both psychoanalytic theory and practice have pushed the psychoanalytic therapist from a position of presumed knowing and automatic authority towards a more full, complex and parallel participation in the therapeutic process. This dethroning corresponds to the more general undermining of the expert in the postmodern critique of established knowledge and power relations. It is argued that the shift has come about within psychoanalysis by the increasingly environmentalist tilt in theory, by the ascendance of countertransference thinking, and by the demise of the natural science model for psychoanalytic theory. Some implications for practice deriving from these changes are discussed.  相似文献

Abstract

Hepatitis B immunization is recommended for all American children, and hepatitis A immunization is recommended for children who live in areas with elevated disease rates. Because hepatitis A and B occur most commonly in young adults, the authors examined the cost effectiveness of college-based vaccination. They developed epidemiologic models to consider infection risks and disease progression and then compared the cost of vaccination with economic, longevity, and quality of life benefits. Immunization of 100,000 students would prevent 1,403 acute cases of hepatitis A, 929 cases of hepatitis B, and 144 cases of chronic hepatitis B. Hepatitis B vaccination would cost the health system $7,600 per quality-adjusted life year (QALY) gained but would reduce societal costs by 6%. Hepatitis A/B vaccination would cost the health system $8,500 per QALY but would reduce societal costs by 12%. Until childhood and adolescent vaccination can produce immune cohorts of young adults, college-based hepatitis immunization can reduce disease transmission in a cost-effective manner.  相似文献

Abstract

In this paper we examine the hours of paid work of husbands and wives in 10 industrialized countries, using data from the Luxembourg Income Study. We present results on the average hours of paid work put in jointly by couples, on the proportion working very long weekly hours, and on gender equality in working time within families. The United States ranks at or near the top on most indicators of working time for couples, because of (1) a high proportion of dual-earner couples; (2) long average work weeks, especially among women; and (3) a high proportion of individuals who work very long hours. In terms of gender equality, the United States ranks above average in paid working time among dual-earner couples with no children but fares less well among working parents. Finally, we discuss policies and institutions that may help explain the distinctive United States results, namely the long hours and moderate levels of gender equality, including the regulation of maximum hours, the demand for part-time work, and the public provision of child care.  相似文献
