A permutation approach for testing heterogeneity in two-sample categorical variables

In many sciences researchers often meet the problem of establishing if the distribution of a categorical variable is more concentrated, or less heterogeneous, in population P ₁ than in population P ₂. An approximate nonparametric solution to this problem is discussed within the permutation context. Such a solution has similarities to that of testing for stochastic dominance, that is, of testing under order restrictions, for ordered categorical variables. Main properties of given solution and a Monte Carlo simulation in order to evaluate its degree of approximation and its power behaviour are examined. Two application examples are also discussed.

Queer visual pleasures and the policing of male sexuality in responses to images of David Beckham

Since he stepped out in a sarong in 1998, David Beckham's sexuality and gendered image has been a popular topic of discussion in the media. He has also attracted academic attention for the expanded range of masculinities he seems to represent. Some academic studies of Beckham have employed ‘queer theory’ to analyse the destabilising of gender that his public presentations seem to embody but little attention has been paid to the specifically visual dynamics of images of Beckham. In this essay, I take Sam Taylor-Wood's David (2004) as a starting point to suggest the types of visual pleasure that images of Beckham might be seen to offer to both male and female audiences. For the remainder of the essay I focus on an Armani male underwear advertisement from the 2007–2008 campaign. Informed by discourse analysis and queer theory, I identify a set of ‘queer’ responses to the advertisement, suggesting they represent the ‘policing’ of male sexuality, which often accompanies potential signifiers of homoeroticism. I conclude by considering how and why Beckham has retained his status as a heteronormative masculine icon despite his continued appearance in homoerotic images.     

Treatment of incarcerated, sexually-abused adolescent females: an outcome study

This study examined the psychosocial functioning of 100 adolescent females (ages 12-17) sentenced to secure care in a southeastern state and the impact of gender-specific, cognitive-behavioral therapy (CBT) intervention on the psychosocial functioning of subjects who reported a history of sexual abuse. The Multidimensional Adolescent Assessment Scale (MAAS) was used to assess psychosocial functioning. Pre-test scores on the MAAS revealed significantly higher scores on 12 of 16 dimensions of psychosocial functioning and higher rates of serious criminal behavior for youth who subsequently disclosed sexual abuse histories as compared to those without such histories. At post-test, statistically significant improvements in psychosocial functioning were observed on 14 of 16 MAAS subscales for those who received the CBT intervention. Thus, incarcerated female adolescents who reported a history of sexual abuse demonstrated more impairment in their functioning as compared to those without a reported history of sexual abuse and responded positively to gender-specific, CBT-based intervention.     

The impact of ethnicity on attitudes toward health care reform in New Mexico

Latinos tend to have significantly lower levels of access to general and top quality medical care than do non-Latino whites, and although disparities in access to health care have diminished for all other minority groups over time, they have widened for Latinos. Given these trends, current attempts to provide universal health care at both the national and state levels across the United States have large implications for the health status of Latinos. The objective of this analysis is to determine whether Latinos have different attitudes regarding health reform than non-Latino whites. Our data are from a statewide random digit dialing telephone survey of New Mexico residents, age 18 and older, conducted in the Fall of 2007. With a Latino population of 44% and ongoing health care reform efforts by the state legislature, New Mexico is an ideal location for this analysis. After controlling for a host of individual level factors, our findings suggest that while Latinos are less likely to identify health care as a salient state issue relative to the economy and crime, they are more likely than non-Latino whites to believe affordable health care programs are important. Finally, Latinos view employers, more than government or individuals, to be responsible for expanding health care coverage.     

Examining the Psychosocial Functioning and Characteristics of Incarcerated Girls with a Substance Use Disorder

The purpose of this study was to identify the psychosocial characteristics of incarcerated girls with a substance use disorder. Profile analysis, the repeated measures extension of multivariate analysis of variance, was conducted to compare a state-based sample of incarcerated girls with (n = 140) and without (n = 63) a substance use disorder across multiple subscales of the Multidimensional Adolescent Assessment Scale. Girls with a substance use disorder had higher levels of problem severity. They were more likely to have problems related to alcohol use, drug use, aggression, and cognition. Incarcerated girls with a substance use disorder may benefit from intense interventions that focus on cognitive restructuring or cognitive recovery, and interventions that promote coping and stress management skills.
