Gay affirmative practice has recently been introduced into the social work literature as a culturally sensitive model for
working with gay, lesbian, and bisexual (GLB) adults, however, this model has rarely been applied to practice with GLB youth.
In this article, the authors review the literature to present the main tenets of gay affirmative practice, outline the challenges
that GLB youth face, and delineate the environmental and individual strengths that can be enhanced to promote well-being.
The authors then apply the gay affirmative practice model to GLB youth, offering concrete information about the specific knowledge,
attitudes, and skills that social workers should acquire to better serve the unique, yet diverse, needs of GLB youth. 相似文献

Cultural and professional associations are the expression of the modern society with structured organisations. The 19th century was the marking epoch of the constitution of associations in Germany. The involvement of associations in the political live, specially the professional ones, is typical in Germany. While political sciences focus on the analyses of interest representation and mediation functions of organisations, sociology research covers the full range of social, psychological, political and economical functions of organisations. Management and especially human resource management topics are presently gaining a growing importance within the research community which focuses on the cultural and professional organisations. 相似文献

Sets of alternatives as Condorcet winners 总被引:1,自引:0,他引:1
We characterize sets of alternatives which are Condorcet winners according to preferences over sets of alternatives, in terms
of properties defined on preferences over alternatives. We state our results under certain preference extension axioms which,
at any preference profile over alternatives, give the list of admissible preference profiles over sets of alternatives. It
turns out to be that requiring from a set to be a Condorcet winner at every admissible preference profile is too demanding,
even when the set of admissible preference profiles is fairly narrow. However, weakening this requirement to being a Condorcet
winner at some admissible preference profile opens the door to more permissive results and we characterize these sets by using
various versions of an undomination condition. Although our main results are given for a world where any two sets – whether
they are of the same cardinality or not – can be compared, the case for sets of equal cardinality is also considered.

The importance of women on the bench and the influence of gender on judicial decision making has garnered much scholarly attention. We examine the voting behavior of male and female justices in 718 Fourth Amendment search and seizure votes cast on state Supreme Courts between 1980 and 2000. We find that women justices, controlling for institutional, political, and legal constraints, are more likely to rule in favor of the criminal defendant than their male brethren in cases decided after 1991 but not before. We also find women justices serving with female colleagues are more inclined to render liberal votes. We conclude the influence of gender may be evident in a wider variety of cases than those dealing with women's lives but that this influence is dependent upon the existence of a critical mass of women on the state court benches. 相似文献

We employed 4,095 couples from both waves of the National Survey of Families and Households (NSFH) to test a model of couple violence drawn from several theoretical perspectives. The outcome distinguishes among nonviolent couples and those experiencing either physical aggression or intense male violence. According to the model, background characteristics of couples are related to relationship stressors, which affect the risk of violence via their tendency to promote verbal conflict. Considerable support for the model was found. Couples were at higher risk for one or both forms of violence if they were younger at union inception, had been together for less time, were both in their first union, had only one partner who was employed, had a nontraditional woman paired with a traditional man, had at least one partner who abused substances, had more children, had more frequent disagreements, exhibited a more hostile disagreement style, or lived in an economically disadvantaged neighborhood. Moreover, the effects of stressors such as the number of children and couples' employment status disparities appear to be mediated by disagreement frequency and disagreement style. 相似文献

We consider the problem of density estimation when the data is in the form of a continuous stream with no fixed length. In
this setting, implementations of the usual methods of density estimation such as kernel density estimation are problematic.
We propose a method of density estimation for massive datasets that is based upon taking the derivative of a smooth curve
that has been fit through a set of quantile estimates. To achieve this, a low-storage, single-pass, sequential method is proposed
for simultaneous estimation of multiple quantiles for massive datasets that form the basis of this method of density estimation.
For comparison, we also consider a sequential kernel density estimator. The proposed methods are shown through simulation
study to perform well and to have several distinct advantages over existing methods. 相似文献
