VII. Conclusion The number of immigrants now coming to the United States is proportionally only a fraction of the number that came in earlier
years, and there is nothing in those numbers to suggest a difficult absorption burden. Immigrants, both legal and illegal,
more than pay for the services they use with the taxes they pay, leaving a considerable net surplus that benefits American
citizens. Immigrants raise productivity and do not cause an observable amount of unemployment of citizens. Admitting far more
immigrants into the country than the law now allows would have positive effects on the incomes of citizens, and would enhance
the continuing vitality of the United States. 相似文献

In our zeal to deal with alcohol and drug abuse, we may have a distorted picture of what the majority of college students actually think about alcohol and drug use. Students in this study done at a public university located in the Deep South report being generally intolerant of substance abuse. 相似文献

The theory of family paradigms provides an integrative framework for under-standing and systematizing the diverse ways that families organize and make sense of family life. Using formal methods of analysis based on logical and geometrical arguments, the priecise implications of models of family types can be investigated and compared. The paradigmatic framework can thus be refined and extended to form a more rigorous theoretical grounding for family typologies is explored and a miltidimensional model is derived the geometry of which is equivalent to, but more succinctly captures, the underlying structure of uariation in family para-digms. In Part II, the resulting model is interpredtd and explored in terms of implications for family theory, theory construction, and family therapy. Clarifying the basic dimensions of the paradigmatic framework also permits more precise exploration of interrelationships among related models of family types, which can be understood as reduced models derivable from the complete geometry of the paradigmatic framework. 相似文献

Primary care physicians are well situated to identify patients with substance abuse problems and motivate them to seek appropriate assistance, but active programs are the exception. A study in a community setting was undertaken to assess the CAGE (the first letters of key words in a series of four questions about drinking: cut down; annoyed; guilty; and eye-opener), instrument in the routine screening for alcohol problems in both new and established patients. The screening process identified subjects for a pilot evaluation of a motivational interview designed to encourage problem-solving behavior. This article focuses on the screening results and the use of the CAGE instrument. During June and July of 1990, 687 patients of two primary care physicians belonging to a large group practice were asked to complete a health questionnaire that included the CAGE. Those who responded affirmatively to at least two of the four CAGE questions were requested to participate in follow-up assessment of problems associated with alcohol and health. The type and severity of alcohol problems experienced by patients who scored positive on the CAGE are described. Prevalence of a positive score on the CAGE was 8.6 percent with males, smokers, and blue collar and unemployed persons being more likely to score positive. The positive predictive value was .68. Primarily, persons with moderate alcohol problems were identified. Results show that the CAGE instrument is a useful screening device for identifying those with mild to moderate substance abuse problems, increasing the opportunity for intervention prior to serious medical complications. The instrument is easily administered, and has demonstrated relatively high levels of sensitivity and specificity. When combined with assessment and motivational interviews, the CAGE shows promise in the secondary prevention of substance abuse and related health problems. 相似文献

Definitions of social roles and the maintenance of a working consensus are two kinds of background expectations which are important for actors’accomplishment of self-work. Interactionists have traditionally assumed that these background expectations are unambiguously available to social actors as they negotiate situated meanings of selves and situations. Using data from dyadic role-play conversations, this study examines instances where interactants reference these expectations as ambiguous or problematic. The findings show that the situated meanings of role definitions and the working consensus are continually subject to potential negotiation. The implications of these findings for future research and theory on self-work in social interaction are discussed. 相似文献

Popular contemporary rhetoric of the self advocates knowing the needs of the self and reaching a balance between self and other. As a consequence of economic dependence on men, women have emotional obligations that make meeting these goals unlikely. The recently identified condition called codependency addresses the tensions underlying this situation. Recovering from codependency serves as an aligning action that accounts for past behavior using the quasi-medical rhetoric of addiction. The sick role then allows for small amounts of deviance from female gender role norms in that it permits women to exercise some self-determination in the allocation of their time and emotions. Although critics have ignored the possibility, codependency can provide a tool of resistance for those who have few resources to challenge the status quo. 相似文献

This paper presents a new Laplacian approximation to the posterior density of η = g(θ). It has a simpler analytical form than that described by Leonard et al. (1989). The approximation derived by Leonard et al. requires a conditional information matrix Rη to be positive definite for every fixed η. However, in many cases, not all Rη are positive definite. In such cases, the computations of their approximations fail, since the approximation cannot be normalized. However, the new approximation may be modified so that the corresponding conditional information matrix can be made positive definite for every fixed η. In addition, a Bayesian procedure for contingency-table model checking is provided. An example of cross-classification between the educational level of a wife and fertility-planning status of couples is used for explanation. Various Laplacian approximations are computed and compared in this example and in an example of public school expenditures in the context of Bayesian analysis of the multiparameter Fisher-Behrens problem. 相似文献

Abstract This paper examines rural/urban differences and trends in mental health during the farm crisis of the 1980s in a large panel sample from a midwestern state. A community research perspective, which attributes differences to life styles, culture, and community context, is contrasted with an economic stress perspective, which focuses on individual differences in economic circumstances as determinants of rural-urban differences in mental health. Survey samples from 1981, 1986, and 1989 are used to examine differences among seven categories of community type. Multiple regression analysis of the trend and panel data provide support for both the individual economic distress and community context models. 相似文献
