Back-to-back mixtures of discrete distributions

A method for expanding the choices for fits of discrete data is given. The method is very simple: a breakpoint is chosen for the data set on either side of which two separate discrete distributions are fit. Thus, the method is a mixture of two discrete distributions. The method is appealing in light of the ease with which the likelihood equations simplify. For illustrative purposes, the method is used on the data set that motivated its conception.     

An Analysis of Specific Life Satisfaction Domains and Disordered Eating among College Students

Research has revealed that overall life satisfaction (LS) is negatively related to disordered eating. This study examined whether specific LS domains (e.g., family, friends, etc.) were more strongly associated with eating behaviors/weight perceptions (e.g., exercising to lose weight, using laxatives to lose weight, etc.) in 723 randomly selected college students analyzed separately by gender. Data were analyzed using logistic and multiple regression procedures. Results supported the hypotheses in the expected directions. College students’ weight perceptions had the strongest relationships with Satisfaction with Self and Satisfaction with Physical Appearance, and these relationships were stronger among females than males. Worrying about weight, self-described weight, and binge eating were significantly correlated with all LS domains (p < .05). Results suggest potential contributions of differentiating among the domains of LS in efforts to understand disordered eating among males and female college students. Implications for practice are discussed briefly.     

Attitudes Toward Lesbians and Gays Among American and Dutch Adolescents

Attitudes toward lesbians and gays vary across national populations, and previous research has found relatively more accepting attitudes in the Netherlands as compared to the United States. In this study, we compared beliefs about and attitudes toward lesbians and gays in samples of Dutch and American heterosexual adolescents, utilizing survey data from 1,080 American adolescents (mean age = 15.86 years) attending two schools and from 1,391 Dutch adolescents (mean age = 16.27 years) attending eight schools. Findings indicated the Dutch participants were more tolerant of lesbians and gays, after adjusting for the gender, age, and racial/ethnic minority status of the participants. However, between-country differences were attenuated by accounting for the beliefs about lesbians and gays that participants used to justify their attitudes. American participants were more likely to justify their attitudes using beliefs related to social norms and religious opposition, while the Dutch participants were more likely to justify their attitudes using beliefs related to individual rights and the biological/genetic basis of homosexuality. The results suggest that the relative importance of particular beliefs about lesbians and gays to attitudes at the group level may be context dependent but also that certain beliefs are salient to attitudes across national contexts.     

Reviewing Implications of Urban Growth Management and Spatial Governance in the Global South

ABSTRACT

Urban containment policies have been applied in the global north as a strategy towards creating compact urban development. In the south the urban growth management discourse have been part of planning practice for the past three decades. There are however several reasons, both structural and political that have contributed to its limited success. The purpose of the research is to review practices of growth management in the south in an attempt to find lessons from the implementation of different mechanisms. The study focuses on the challenges of growth management mechanisms and its associated spatial governance approaches.     

The relationship between perceived quality and divulgation strategies of products in the electronic marketplace

This article introduces concepts regarding management design, the electronic marketplace and recommendation systems, as well as uses a revised bibliography proposing the relationship between applied management design strategies and recommendation products identified through Cazella and the different types of perceived quality developped by Michalos and Schwartz.     

A Qualitative Exploration of the Premigration Victimization Experiences of Sexual and Gender Minority Refugees and Asylees in the United States and Canada

Progress in analyzing and interpreting the concepts of sexual orientation and gender identity in the context of refugee law has contributed to a rise in individuals seeking asylum in such countries as the United States and Canada. However, few studies have examined the victimization experiences of sexual- and gender-identity forced migrants prior to their arrival in North America. This qualitative study used thematic analysis to explore the premigration adult victimization experiences of 26 lesbian, gay, and transgender individuals who obtained refugee, asylee, or withholding-of-removal status in the United States or Canada based on persecution for their sexual orientation and/or gender identity. Participants originated from countries in Asia, Africa, the Caribbean, Eastern Europe, Latin America, and the Middle East. Analysis revealed the following themes: living on the edge, adopting concealment strategies, routine victimization, and protectors as perpetrators. Participants described living in a constant state of hypervigilance, and they adopted numerous strategies to protect themselves from victimization. Despite the use of such strategies, participants experienced victimization by community members and state actors, leaving them no choice but to flee to ensure their safety and well-being. Findings are discussed using the ecological framework outlined by the World Health Organization (WHO). The discussion concludes with implications for international policy and clinical practice.     

Fatherhood, cohabitation, and marriage

In “Fatherhood, Cohabitation, and Marriage,” Wade F. Horn, Assistant Secretary for Children and Families at the Department of Health and Human Services, summarizes the importance of fathers to child well-being. He explains that “fatherlessness is a significant risk factor for poor developmental outcomes for children.” This connection has led some observers to view cohabitation as a substitute or at least an alternative to marriage. Horn argues, however, that marriage is the best option for children and that cohabitation is a weak family structure compared with marriage. Children in households with married parents do better on almost every measure of child well-being, even after controlling for income.     

Prisoners of Conscience

Amnesty International is a human rights organisation that operates right around the world. This article describes its objectives and methods, and discusses some of the factors which have contributed to its successful growth over the past 27 years. It also looks at the relationships between the organisation, the offending authorities and the victims of oppression and their families.
