Split labor market theory was originally advanced as a general approach explaining ethnic antagonism as the result of class-based interests. In this investigation, the threat to “high-priced” (white) labor from “cheap” (black) labor within the farm tenancy system of the postbellum South is examined as an underlying cause of the lynching of blacks by whites. Supporting this interpretation, the ratio of black to white tenants in southern counties, a measure of the level of economic threat to high-priced labor, is shown to be a strong predictor of lynching rates in the Cotton South. Findings for the Non-Cotton South, however, are inconsistent with theoretical expectations. We conclude that racial violence linked to economic competition between working-class whites and blacks was limited to that part of the South dominated by the plantation system.  相似文献

Transition probabilities can be estimated when capture-recapture data are available from each stratum on every capture occasion using a conditional likelihood approach with the Arnason-Schwarz model. To decompose the fundamental transition probabilities into derived parameters, all movement probabilities must sum to 1 and all individuals in stratum r at time i must have the same probability of survival regardless of which stratum the individual is in at time i + 1. If movement occurs among strata at the end of a sampling interval, survival rates of individuals from the same stratum are likely to be equal. However, if movement occurs between sampling periods and survival rates of individuals from the same stratum are not the same, estimates of stratum survival can be confounded with estimates of movement causing both estimates to be biased. Monte Carlo simulations were made of a three-sample model for a population with two strata using SURVIV. When differences were created in transition-specific survival rates for survival rates from the same stratum, relative bias was <2% in estimates of stratum survival and capture rates but relative bias in movement rates was much higher and varied. The magnitude of the relative bias in the movement estimate depended on the relative difference between the transition-specific survival rates and the corresponding stratum survival rate. The direction of the bias in movement rate estimates was opposite to the direction of this difference. Increases in relative bias due to increasing heterogeneity in probabilities of survival, movement and capture were small except when survival and capture probabilities were positively correlated within individuals.  相似文献

EFFICACY OF FAMILY THERAPY FOR DRUG ABUSE: PROMISING BUT NOT DEFINITIVE   总被引:2,自引:0,他引:2  
Drug abuse is an enormous public health problem with consequences not only for individuals using drugs but also for families, communities, and society. Moreover, research evidence and clinical experience agree that drug abuse is one of the more difficult problems to treat. Despite considerable research on the connection between family factors and drug use, and the existence of family therapy models for drug abuse, comparatively few controlled efficacy studies have been conducted. This article presents a critical review of controlled treatment outcome research in the area of family therapy for drug abuse in both adults and adolescents. A number of studies from different clinical research groups demonstrate that different versions of family intevention can engage and retain drug users and their families in treatment, significantly reduce drug use and other related problem behaviors, and enhace particular domains of prosocial functioning. Moreover, a smaller number of comparative efficacy studies have shown family therapy to be more effective than nonfamily therapies. Family therapy of adolescent drug abuse is more developed at present than family therapy of adult drug abuse. Although the results of the reviewed studies are promising, a blanket confirmation of family therapy's efficacy for drug abuse cannot be made at this time because of the relatively small number of studies and the noted methodological limitations of the studies published to date. Nonetheless, substantial progress in this clinical research area has occurred, and if research and funding support continue or can expand, significant breakthroughs in the treamtment of drug abuse with family-based treatments are possible.  相似文献

Describing the unsettling effects of adding family therapy procedures to the offerings of a mental health clinic, the author argues that changes in the theory of causation, diagnosis, therapeutic technique, and clinical training are required in order to make such an innovation. Consequences are likely to include disorientation of the staff, radically changed administrative procedures, and others, including service to larger numbers of people and better treatment outcome.

There is a considerable literature on transfer pricing. One strand of this literature is empirical and is concerned with the extent to which companies use the various transfer pricing methods. The other strand is strongly normative being directed to devising transfer pricing methods and defining the circumstances under which it is appropriate to use them. This study attempts to address both these questions by using discriminant analysis methods to predict which approach a company will use to determine transfer prices given its weightings of certain ‘determinants’ which theory suggests should be relevant to the decision. Domestic and international transfer pricing are considered separately. Discriminant analysis is shown to be quite successful in predicting the transfer pricing systems adopted by the UK companies surveyed.  相似文献

Much is revealed through the contrast of two related but divergent forms. In this essay, Elizabeth Mechlingand Jay Mechlingcontrast Disneyland with a later but more loosely themed park, Marriott's Great America in Santa Clara, California. Using the perspectives and methods of semiotics in Louis Marin's Marxist reading, this essay asks, “What are the stories that Disneyland and Marriott's Great America tell?…the ways in which popular culture both teaches and evokes stories that ‘think themselves’ in our minds.” These two parks, though allied in the theme format and rooted in a common bourgeois capitalist culture, are found to promote very different attitudes and values.  相似文献

The most serious problem facing the United States, accordingto many scientific and political leaders, is the threat of nuclearwar. Yet the standard survey question on the most importantproblem facing the country has often shown little public concurrencewith this assumption. Our article uses experimentation in nationalsamples to test whether this difference can be traced to limitationsin either the form or the wording of the standard question.The results indicate that there are some important systematicdifferences between open and closed versions of the question,and also differences that result from reference to the nationas distinct from the world, but neither type of difference accountsfor the infrequent mention of nuclear war on the standard question.Instead, other evidence indicates that most Americans believethat nuclear war is not going to happen at all, or that if itdoes happen it will be too far in the distant future to be ofpressing concern to them personally.  相似文献
