Some contributions on the multivariate Poisson–Skellam probability distribution

In this article, we introduce a new form of distribution whose components have the Poisson or Skellam marginal distributions. This new specification allows the incorporation of relevant information on the nature of the correlations between every component. In addition, we present some properties of this distribution. Unlike the multivariate Poisson distribution, it can handle variables with positive and negative correlations. It should be noted that we are only interested in modeling covariances of order 2, which means between all pairs of variables. Some simulations are presented to illustrate the estimation methods. Finally, an application of soccer teams data will highlight the relationship between number of points per season and the goal differential by some covariates.     

Uncovering the Truth: The Lake Perućac Exhumations in Eastern Bosnia

The aggression and genocide in Bosnia and Herzegovina (BiH) from 1992 to 1995 left an estimated 30,000 missing persons mainly Bosniaks (Bosnian Muslims). These victims consisted of mostly male civilians, but also a significant number of women, elderly and children. Remains of victims are being uncovered in mass graves by expert teams since 1996. The mass graves included various sites spread across the territory that became known as Republika Srpska after the war ended. In many cases ravines, rivers and lakebeds were used as mass graves where the bodies were dumped and hidden. This article describes the largest operation to uncover human remains of victims in BiH and beyond, which took place in 2010, and was undertaken by the Missing Persons Institute of BiH on the dried up surface of the Peru?ac Lake on the Drina River in Eastern Bosnia. This article aims to record the important aspects of the operation and the personal stories of the victims found.     

Are There Gender-based Effects for an Educational Program for Parents of Adolescents With Risk Behaviors?

The goals of this study were to evaluate the gender-based effectiveness of the parental intervention of the Suspertu (“recovery” in English) prevention program for adolescents with risk behaviors in Spain. The sample included 229 parents (105 fathers and 124 mothers). One open-label trial with repeated measures was used. Parents received a family therapy and a group education. The intervention improved parents’ authoritative parenting style, decreasing the degree of parental stress and reducing parent’s psychopathological symptoms and maladjustment. Improvement in both groups (fathers and mothers) was mainly observed from pre- to post-intervention assessment. According to the results, prevention programs for adolescents with risk behaviors may be a suitable context both to teach parents to deal appropriately with their children’s risk behaviors, and to improve parent’s psychological state.     

The Touchard distribution

We present a novel model, which is a two-parameter extension of the Poisson distribution. Its normalizing constant is related to the Touchard polynomials, hence the name of this model. It is a flexible distribution that can account for both under- or overdispersion and concentration of zeros that are frequently found in non-Poisson count data. In contrast to some other generalizations, the Hessian matrix for maximum likelihood estimation of the Touchard parameters has a simple form. We exemplify with three data sets, showing that our suggested model is a competitive candidate for fitting non-Poisson counts.

Relationships Between Religiosity Level and Attitudes Toward Lesbians and Gay Men Among Turkish University Students

This study examined the relationships between religiosity levels and attitudes toward lesbians and gay men among freshmen university students in Turkey. The Attitudes Towards Lesbians and Gay Men Scale–Short Form and the Religiosity Scale were administered to 91 male (M = 19.95, SD = 1.48 years) and 171 female (M = 19.23, SD = 1.28 years) students. The findings showed that male freshmen (M = 19.32, SD = 4.97) had more negative attitudes toward gay men than toward lesbians (M = 17.84, SD = 5.25), p = .000. In addition, attitudes of male freshmen were significantly more negative toward gay men (M =19.32, SD = 4.97) than females (M = 17.51, SD = 5.73), p = .012. Both male and female freshmen students who had higher levels of religiosity were found to have higher levels of negative attitudes toward both lesbians and gay men.     

Social inclusion for whom and towards what end? A critical discourse analysis of youth and sport policies in Turkey

This article examines the social inclusion policy strategies of the Turkish Ministry of Youth and Sport (MYS). Using a critical discourse analysis, based on Norman Fairclough’s work (2012), the aim is to analyse the discourses used within policy-related documents regarding social inclusion, youth, and sport. In order to achieve this objective, we analysed 15 key documents, including annual activity reports, national youth and sport policy documents, and strategic plans produced by the Ministry. Findings revealed that the dominant discourses about young people seem to be embedded within neoliberal and neoconservative ideologies in which depoliticised notions of ‘employment/apprenticeship’ and ‘the family’ are put forward as solutions for the social inclusion of young people. However, such a discourse risks further sustaining the social exclusion of youth, denying their full citizenship.     

Has the HIV Epidemic Peaked?

This study reviews the highly diverse regional and country patterns of HIV epidemics and discusses possible causes of the geographic variation in epidemic sizes. Past trends and projections of the epidemics are presented and the peak years of epidemics are estimated. The potential future impact of new prevention technologies is briefly assessed. A final section summarizes the future impact of the epidemic on key demographic variables. The main finding of this analysis is that the HIV epidemic reached a major turning point over the past decade. The peak years of HIV incidence rates are past for all regions, and the peaks of prevalence rates are mostly in the past except in Eastern Europe, where they are expected to peak in 2008. But owing in part to the life‐prolonging effect of antiretroviral therapy and to sustained population growth, the absolute number of infected individuals is expected to keep growing slowly in sub‐Saharan Africa and to remain near current levels worldwide, thus posing a continuing challenge to public health programs. No country is expected to see a decline in its population size between 2005 and 2050 that is attributable to high mortality related to AIDS.
