A wellknown result of CHERNOFF on the convergence rate of the 2nd kind error in testing two simple hypotheses is generalized to the case of finite hypotheses by help of methods of linear programming and the asymptotic behaviour of the corresponding least favourable distribution is investigated. 相似文献

The purpose of this research study was to increase our understanding of how families living in poverty successfully meet life challenges. Family resiliency provided the theoretical framework for examining family coping and adaptation. This study used a purposive sample of women (N = 128) in families with children attending Head Start. All families lived below or at poverty level, most with 11th grade education or high-school/GED diploma. Content analysis methods were used for data analysis. Results of this study identify the characteristics that promote competence, including how individual, family, and environmental factors are potential stressors that also may serve to promote family resilience. The data indicate that family love and mutual support, as well as faith, help stressed families cope and maintain meaning in spite of lack of control over life circumstances resulting from economic poverty. 相似文献

In this article we examine the prevalence of and associations between sexual orientation–based verbal harassment and reported utilization of health services across levels of sexual orientation in a diverse sample of adult recipients of Los Angeles County–funded HIV-related health and social services. Thirty-two percent reported they had experienced verbal harassment, the majority (80.3%) of whom identified as lesbian, gay, or bisexual (LGB). Those who reported being verbally harassed received significantly more services overall than those who were not verbally harassed, and service utilization varied by sexual orientation. These findings inform future efforts to identify and assess social discrimination in health and social service settings. 相似文献

The distribution of ant colonies within a community is often well defined, yet this distribution can change due to changing environmental conditions, resource availability, and colony growth. In this study, structure infesting ant communities were sampled for one year within three Puerto Rican housing developments of different ages. These developments represented environments in different stages of recovery after a disturbance (secondary succession). Spatial mapping was used to plot the distribution and abundance of ant communities within these developments. At the beginning of the study, the youngest housing development (1 year since construction), had the fewest number of species present (ave. 1.6 per house). The second housing development (4 years old) had a greater number of species (ave. 2.6 per house), and a greater sampling frequency (the same species collected at multiple houses) than Site 1. The oldest development (8 years old) had both the greatest number of species (ave. 2.7 per house), and sampling frequency of the three sites. In all developments, the number of species, sampling frequency, and ant biomass increased throughout the year as colonies grew and foraging ranges expanded. It was observed in all developments, that species coexistence also increased throughout the year. As colony populations increased, there was a greater occurrence of multiple species being collected at the same sample house. In the youngest development, the two most dominant species increased in numbers during the year and began to be collected from the same sample houses. Spatial diagrams documented that multiple species in the older housing developments (later stages of succession), also shared a common distribution. Even the most dominant species (S. invicta) in all three sites, did not exclude additional species from foraging within its established range. 相似文献

The social work profession has been too little concerned with policy, program, and practice issues related to human sexuality. Changing times and new knowledge require that the profession deal with this area more competently. Studies indicate that human sexuality is affected by biological, cultural, and psychological factors; that the female and male sex drives and physiological responses are similar; that the incidence of premarital and extramarital sexual relations are probably increasing along with more emphasis on the quality of the total interpersonal relationship; and that sexual behavior and values vary between socioeconomic groups. 相似文献

Abstract The merging of videodiscs and computers now makes possible a variety of exciting instructional strategies in education. This article highlights the ways in which videodiscs can be utilized to individualize the pace of student learning and to enhance the transfer of new learning from the classroom to beginning professional encounters. Ranging from concept learning to simulations of client-worker interactions, the application of videodisc technology to classroom instruction enables the blending of theory and practice so valued by social work educators. 相似文献

The Lacanian concept of the masculine and feminine as symbolic positions, which may or may not correspond to anatomy, is clinically useful in the case of Mr. M. This discussion suggests that these concerns can be addressed by the feminist Lacanian theorists (Ragland, 1995), who discuss language within the landscape of primary repression as well as secondary repression. The analyst here illustrates the insufficiency of listening or speaking from only a preoedipal/maternal or an oedipal/paternal position; both are needed. In this discussion, the factors of sexual difference, psychosexual identification, gender definitions, and object choice are described in their different relations to one another when in preoedipal land (the Law of Language) versus the oedipal territory (Law of the father/culture). In summary, it could be said that stuttering or the inability to speak one's name is an incomplete weaning–there is no “I” who speaks from a secure symbolic indentification. 相似文献

“Hookups”: Characteristics and correlates of college students' spontaneous and anonymous sexual experiences 总被引:1,自引:0,他引:1
This study focused on a specific risky practice common among contemporary college students: the hookup. Hookups are defined as a sexual encounter which may or may not include sexual intercourse, usually occurring on only one occasion between two people who are strangers or brief acquaintances. The aim of this study was to determine the relative importance of a variety of social and psychological predictors in understanding differences among undergraduate students who had never hooked up, those who had hooked up without sexual intercourse, and those who had hooked up with sexual intercourse. Analyses revealed that, as predicted, social, individual, and relational psychological variables helped to explain the variance among college students' varied hookup experiences. By examining the full range of sexual involvement characteristic of the casual sexual phenomenon of hooking up within a multivariate model, we were able to achieve a more differentiated understanding of college students' casual sexual experimentation. 相似文献
