Black and white population change in small American suburbs since World War II: regional differences
Stahura JM 《Sociological focus》1988,21(4):317-329
"This study examines the relationship between black population concentration (% black), black population change and white population change for small American suburbs for the 1950-1980 period. Linear, tipping point (curvilinear) and interaction models of racial transition are evaluated for each decade by region (South and non-South), controlling for several other suburban characteristics (age, annexation and distance to the Central Business District) which may affect both black and white population change. The analyses show that racial transition in suburbs involves the parallel development of white and black populations with mainly weak and complex causal linkages which are sensitive to broader suburbanization patterns." 相似文献

In a six-year study on a locked psychiatric hospital unit for adolescents, first patients and then their families became integrated into the interdisciplinary treatment team. The results were universally beneficial. After initial resistance and some fine tuning of their skills, the staff became strong supporters of the program. Parents, no longer one down, developed a close working relationship with the therapists and milieu staff. Treatment planning and implementation was enriched by the interaction and dissension was minimized. Most important of all, the adolescents improved more rapidly and hospital stays were significantly shortened. 相似文献

The medical model as a conceptual and operative approach to compulsive gambling is discussed. The terms medical model and disease are defined and the practical implications of their application to compulsive gambling are explored. Special attention is given to the addictive disease concept. Finally, a variety of objections to the medical model are described, but it is concluded that the many individual and social advantages of the medical model make it the preferred conceptualization at our present state of knowledge. 相似文献

A questionnaire was designed to test selected aspects of the author's General Theory of Addictions (Jacobs, 1982). Data were collected from groups of compulsive gamblers, alcoholics, and compulsive overeaters, and compared with the responses to the same questionnaire obtained from normative samples of adolescents and adults. The more inclusive term, compulsive gambler, has been used throughout, since the sample of gamblers in this study included an inpatient subgroup who had been diagnosed as pathological gamblers, as well as a subgroup of Gamblers Anonymous members who had not been clinically evaluated. Findings support the author's theoretical position that, when indulging, different kinds of addicts will tend to share a common set of dissociativelike experiences that differentiate them from nonaddicts. This has been termed a state of altered identity. 相似文献

BELIEVABILITY AND THE PRESS 总被引:3,自引:0,他引:3
This study looks at believability ratings assigned to 39 newsorganizations and news personalities by a nationally representativesample of 2,104 adult men and women. The data provide threemajor findings about the believability of the American press,all of which, at least in part, tend to be at odds with muchof the conventional wisdom and some of the contemporary researchdealing with the credibility of the news media. First, the overwhelmingmajority of the general public believes most of what it hears,sees, or reads in the nation's press. Second, perceived "believability"of the news media is not closely related to those politicaland demographic variables that typically divide public opinionin America. Third, the public does "group" the news media interms of "believability," but the groupings do not equate withthe dichotomy usually drawn between television and print journalism. 相似文献

"Net undercount rates in the U.S. decennial census have been steadily declining over the last several censuses. Differential undercounts among race groups and geographic areas, however, appear to persist. In the following, we examine and compare several methodologies for providing small area estimates of census coverage by constructing artificial populations. Measures of performance are also introduced to assess the various small area estimates. Synthetic estimation in combination with regression modelling provide the best results over the methods considered. Sampling error effects are also simulated. The results form the basis for determining coverage evaluation survey small area estimates of the 1900 decennial census." 相似文献

Suppose X1, X2, ..., Xm is a random sample of size m from a population with probability density function f(x), x>0 and let X1,m<...m,m be the corresponding order statistics. We assume m as an integer valued random variable with P(m=k)=p(1?p)k?1, k=1, 2, ... and 0 and n X1,n for fixed n characterizes the exponential distribution. In this paper we prove that under the assumption of monotone hazard rate the identical distribution of and (n?r+1) (Xr,n?Xr?1,n) for some fixed r and n with 1≤r≤n, n≥2, X0,n=0, characterizes the exponential distribution. Under the assumption of monotone hazard rate the conjecture of Kakosyan, Klebanov and Melamed follows from the above result with r=1. 相似文献

It is shown that when a parameter lying in a sufficiently small interval is to be estimated in a family of uniform distributions,
a two point prior is least favourable under squared error loss. The unique Bayes estimator with respect to this prior is minimax.
The Γ-minimax estimator is derived for sets Γ of priors consisting of all priors that give fixed probabilities to two specified
subintervals of the parameter space if a two point prior is least favourable in Γ. 相似文献

In this paper the timing of maternity is estimated by a hazard model. The novel aspect of this paper is that it is shown that wages and total household labor income have a significant effect on the timing of maternity. Both the wage rate of the woman and the wage rate of the husband have a negative effect on the timing of maternity. Total household labor income increases the probability of having a child at an earlier age. Calculated elasticities show that the timing of maternity is relatively elastic with respect to wage rates. However, the elasticities of the decision whether or not to have children altogether are much smaller. Women working in the labor market delay the timing of maternity compared to non-participating women. Attending school has the same effect. Until the age of 28 the maternity hazard increases with age, after that it decreases.We benefited from comments on previous drafts by Siv Gustafsson, Joop Hartog, Peter Kee, Herriette Maassen van den Brink, Eddie Mekkelholt, Joop Odink, Hessel Oosterbeek, Hans van Ophem, Gusta Renes, Andre Voskamp, two anonymous referees, and the Managing Editor of this Journal.

1. It is important to examine client and staff satisfaction with the RN case management (RNCM) model to enhance the quality of care in psychiatric settings. 2. Ninety-two percent of clients surveyed ranked the RNCM care as "excellent" or "above average." Clients valued most the humanistic role of the RNCM and repeatedly commented on the importance of the nurse being caring, genuine, and supportive. 3. RNCMs expressed high satisfaction with their role, which they described as collaborative with the psychiatrist, yet also professional and independent. Psychiatrists expressed a high degree of confidence that clients were receiving excellent care by competent nurse professionals. 相似文献
