A Note on Functional Forms of Order Statistics

Functional forms of order statistics, as the solution of a system of equations, are studied. The case of the smaller and the larger of two random variables is discussed in detail. Some applications for normal and binomial distributions are presented.     

Parameter estimation in nonlinear regression models 1

Fisher information contained in record values, inter-record times and their concomitants from a sample of fixed size is derived in general and explicit expressions are deduced for some specific known bivariate classes of distributions. A comparison between fixed sampling and inverse sampling schemes with equal number of records and concomitants is also carried out. We also consider parameter estimation based on bivariate records and a small simulation study is done.     

Sequential confidence intervals for the number of cells in a multinomial population

A two-sided sequential confidence interval is suggested for the number of equally probable cells in a given multinomial population with prescribed width and confidence coefficient. We establish large-sample properties of the fixed-width confidence interval procedure using a normal approximation, and some comparisons are made. In addition, a simulation study is carried out in order to investigate the finite sample behaviour of the suggested sequential interval estimation procedure.     

In Spite of All,We Make It: Themes of Stress and Resiliency as Told by Women in Families Living in Poverty

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.     

Concretizing the Concept of Social Stress

The concept of social stress, as adapted from Selye’s work on biology, is insufficient to explain psychological functioning. To be useful, social stress must include enduring social practices characteristic of particular social systems that violate socially generated as well as biological needs. Some of these stressful events are gender role, poverty, and societal practices such as extreme competition, individualism, and materialism.     

Efficacy of a Group Therapy for Sexually Abused Adolescent Girls

ABSTRACT

The effects of a group therapy program for teenage girls reporting child sexual abuse were evaluated by means of a pretest/post-test design with a control group. The psycho-educational intervention consisted of an average of 20 weekly two-hour meetings. Results of the repeated analyses of variance (ANOVA) revealed a sig-nificant improvement in youth participating in the therapy when compared with the control group on measures of post-traumatic stress, internalizing and externalizing behavior problems, coping strategies, relation- ship with the mother, and sense of empowerment. The findings suggest that the group therapy offered by the Centre d'Intervention en Abus Sexuels pour la Famille (CIASF) was effective in reducing symptoms for sexually abused teenagers.     

Building Strength Through Challenging Homophobia: Liberation Workshops with Younger and Midlife Irish Lesbians

Drawing on the theoretical framework of liberation psychology, this article details workshops on liberation psychology conducted in Ireland with lesbian and transgendered persons aged from early 20's to late 50's. Both younger and older lesbians in the workshops benefited from the opportunity to focus on oppression and to explore options for transformation. The workshops illustrated many of the strengths and vulnerabilities associated with living with homophobia and demonstrated the value of action and engagement. Midlife lesbians were more aware of the systemic nature of homophobia and of the negative emotions related to that. They saw many of these as understandable and even necessary reactions to oppression rather than as negative patterns. These older lesbians tended to be more accepting of the course their lives had taken and of the ways in which choices had been influenced by homophobia and heterosexism. They tended to be more relativistic in their views on coming out, viewing coming out as a decision for each context rather than an overall principle. They valued the importance of community and of activism, and though they were aware of some of the challenges, they also had more positive experiences in this area. These strengths can facilitate managing both homophobia and aging more effectively.     

Evidence-based treatments for trauma among culturally diverse foster care youth: Treatment retention and outcomes

This study describes the implementation of three evidence-based treatments addressing traumatic stress symptoms within a wraparound foster care program in Illinois. Child–Parent Psychotherapy (CPP), Trauma-Focused Cognitive Behavioral Therapy (TF-CBT), and Structured Psychotherapy for Adolescents Responding to Chronic Stress (SPARCS) were implemented with a racially diverse sample of youth ages 3–18 at six agencies. Culturally sensitive adaptations were made to treatment approaches to improve client retention and outcomes. Data analyses revealed no racial differences in retention in the program and no differences in outcomes between minority youth exposed to the intervention and other participants. All three evidence-based treatments were effective in reducing symptoms and improving functioning among minority youth. Implementation issues, including challenges and culturally competent accommodations, are discussed.     

灾难情境下的社会心态研究——“生物—心理—社会”研究思路与方法

从"生物—心理—社会"的视角全面地探讨灾难情境下的人们的社会心态变化规律及其特点有一定的学术价值。生物学视角的研究成果表明,灾难后的心理行为变化源于人类前额叶的高级认知控制功能受到应激影响的条件下转变为由杏仁核所主导的快速情绪反应模式。心理学视角的研究分析认为,灾难后的心理行为变化可看做进化心理学和精神分析理论双重意义上的心理原始化过程。社会文化视角的分析认为,灾难后的心理行为变化可看做一种社会文化心态模式从"平时状态"向"灾难应急模式"的转换。这三个视角的研究分析既有内在本质的联系,也遵循各自不同的逻辑,只有将这三个视角结合起来考虑,我们才能获得对于灾难后社会心态变化的全面认识。     

Laughing Your Way to Peace of Mind: How a Little Humor Helps Caregivers Survive

As the numbers of caregivers continue to increase, more attention is being focused on the unique stresses these individuals experience. Caring for a loved one tests the limits of even the most resilient, regardless of professional status or experience. Laughter is a universal elixir which allows people to cope more sanely with stress and caregiving responsibilities. Research on the emotional and physical benefits of laughter supports the use of humor by professionals and family members who occupy caregiving roles. This article addresses this research and examines common caregiver emotions while providing concrete guidelines for developing humor. Case examples demonstrate how laughter and wit are utilized by those caring for a loved one.
