This paper is a critique of recent service-intensive shelter programs for homeless mothers and the policies that underlie these shelters. We first document the process by which mental health problems and family homelessness became so closely but mistakenly linked. We then demonstrate empirically that shelter programs for homeless families nonetheless presume that mental health problems are part of the causal nexus of family homelessness and indiscriminately deliver mental health services to homeless mothers. Simultaneously, shelter programs encourage the isolation of their residents from what they presume to be their "problematic" social networks. We show that, while mental health services had little impact on depression levels among homeless mothers, isolation from social networks did increase depression among homeless mothers. Our findings suggest that policy should put more emphasis on rapid reintegration into the community through providing housing, and it should put less emphasis on providing services.  相似文献

The patterns of family formation and fertility behavior of Turkish and Moroccan women in Belgium are changing rapidly. The census data (1991) indicate a fertility decline. The reasons are changes in the nuptiality patterns, contraceptive behavior, and migratory flows. The changes are not identical in both communities. Young cohorts postpone their marriage, but this is most prominent among Moroccan women. On the other hand, young Turkish women have a clear preference for smaller families. The changes also differentiate according to migrant "generation" and level of education. The changes are not restricted to Belgium but are also observed in the countries of origin.  相似文献

A system that includes a number of terrorist cells is considered. The cells can consist of one or more terrorists. The current number of terrorist cells is further denoted by N(t), where t is a current time counted from any appropriate origin. The objective is to find the evolution of the system in terms of N(t) and some interpretable parameters, such as the initial number of the terrorist cells N0=N(0), the cell disabling rate constant lambda (or the cell half-life t1/2), and the rate of formation of new cells P. The cost-effectiveness analysis, performed in the framework of the model, reveals that the effectiveness of disabling a terrorist cell is getting worse after 2-3 half-lives of a cell, which shows that if the anti-terrorist actions have not reached their goal during that time, the respective policy should be considered for revision, using the risk assessment consideration. Another important issue raised concerns balancing the efforts related to counterterrorism actions inside the system and the efforts protecting its borders. The respective data analysis is suggested and illustrated using simulated data.  相似文献

This article addresses issues involved in the treatment of fathers who do not have custody of their children. It reviews literature on demographic trends and discusses fathers' reactions to loss of child custody. Assessment and treatment guidelines are offered so that clinical practice may become more responsive to the needs of the population. Gender concerns, particularly as they relate to transference and countertransference, are also discussed.  相似文献

Trust is a prominent determinant of effective interpersonal relationships, group process, and organizational development. However, for leaders and managers, trust building is often problematic. The aim of this article is to contribute to a growing understanding of the way in which individual managers can develop trust in organizations, particularly those defined by medium to high risk. The article presents a theoretical and empirical analysis of the nature of trust at work. Building on the results of an earlier study, use is made of the facet-theoretical approach to generate a definitional framework of trust, which focuses on the characteristics of the trusted person that contribute to the development of trust. Using items developed on the basis of a mapping sentence, hypotheses regarding the relations between the definitional framework and empirical observations were tested through smallest space analysis (SSA) of data collected from a sample of 398 bank and hospital employees. The results demonstrate strong support for the definitional system and show a clear association with results of prior research that identify perceptions of ability, integrity, fairness, and openness as key determinants of trust. The empirical structure clearly reflects the attitudinal nature of interpersonal trust at work and the items empirically distinguish distinct character-based components of trust.  相似文献

Although male sexual abuse has co-existed with female sexual abuse, the professional literature has paid minimal attention to the impact of sexual abuse of male children to their adult adaptation. This paper concentrates on the negative impact of sexual abuse on the adult male's gender identity. Examples of eight male clients' responses to sexual abuse in their adult life and the therapeutic framework utilized to work with them are discussed in the paper.This paper was originally presented at the ICAPP conference, 1993.He teaches advanced clinical practice, Human Behavior and AIDS ELECTIVE. He maintains a private practice specializing in Gay men, persons with HIV virus.  相似文献

In this paper, we report some results on the exact significance level when the usual F-statistic is used in a linear regression model with autocorrelated disturbances. The exact tail area probabilities sometimes differ substantially from the nominal size used in an ‘F-test’ and from upper-bound probabilities derived by Kiviet (1979) which do not depend on the values of the regressors. A similar conclusion is also reached for the exact size of the significance tests for the spurious regressions considered by Granger and Newbold (1974, 1977). The results indicate once more that one has to be careful when using an algebraic F-test in the presence of autoregressive errors. However then too, the Durbin-Watson test is expected to indicate the presence of autocorrelation.  相似文献
