Speeding through the frat house: a qualitative exploration of nonmedical ADHD stimulant use in fraternities

Qualitative methods were used to investigate the use of nonmedical Attention Deficit Hyperactivity Disorder (ADHD) stimulants by fraternity members. The primary goal of the study was to determine students' levels of understanding and motivations for use of these Schedule II controlled substances. Seventy-nine in-depth interviews were conducted. Key findings highlighted how: a) easy it was for subjects to obtain stimulants; b) little health information nonmedical users have about stimulants; c) academic stress created a fertile context for stimulant use; and d) a small number of prescribed users supply the vast majority of nonmedical users with their stimulants. Most nonmedical users claimed to primarily use ADHD stimulants in periods of high academic stress and believed that they not only reduced fatigue, but also increased reading comprehension, interest, cognition, and memory. These qualitative data have supplied a rich and complex understanding behind nonmedical ADHD stimulant use among fraternity members.     

Perceptions of Equal Opportunity among Women and Minority Army Personnel

Equal opportunity (EO) is recognized by the Department of Defense (DoD) as being crucial to maintaining a high state of military readiness. In the last two and a half decades, a number of EO initiatives have been employed by the DoD and each of the military services in an effort to promote fair treatment of minorities and women. Social science literature suggests that the integration of racial minorities, particularly African American males, is a military success story. Some social scientists argue convincingly that the military has far surpassed civilian organizations in integrating African Americans. While the U.S. military has had a long history of addressing racial issues, problems concerning gender have only recently been addressed on a large scale. Some scholars assert that the military is the last male bastion in the United States. It lags behind the civilian sector in integrating women. This study examines the perceptions of active‐duty men and women in the U.S. Army to determine whether minority men are more satisfied with the equal opportunity climate than women and whether minority women are less satisfied with the equal opportunity climate than non‐minority (White) women. The purpose of this study is twofold: One objective is to examine differences within the gender category, i.e., African American, Hispanic, and White women. The other objective is to explore differences across gender. Degree of satisfaction is measured by responses to items on the Military Equal Opportunity Climate Survey (MEOCS). The data were stratified by rank level, officer and enlisted, and a General Linear Model (GLM) was performed with race, gender, and the interaction of race and gender as independent variables. In the final analysis, the data were stratified by paygrade, and a GLM was performed on each part separately. Among the findings, race is a more powerful predictor of the attitudes of active‐duty men and women toward the EO climate in their units than either gender or the interaction of race and gender. While gender is significant in most of the statistical models, and the interaction of gender and race is sometimes significant, these variables explain less than one percent of the variance. Although African American men are generally more satisfied with the EO climate than African American women, they are less satisfied than White and, in some cases, Hispanic men and women.     

A Basis Function Approach to Position Estimation Using Microwave Arrays

We consider the problem of estimating the bearing of a remote object given measurements on a particular type of non-scanning radar, namely a focal-plane array. Such a system focuses incoming radiation through a lens onto an array of detectors. The problem is to estimate the angular position of the radiation source given measurements on the array of detectors and knowledge of the properties of the lens. The training data are essentially noiseless, and an estimator is derived for noisy test conditions. An approach based on kernel basis functions is developed. The estimate of the basis function weights is achieved through a regularization or roughness penalty approach. Choosing the regularization parameter to be proportional to the inverse of the input signal-to-noise ratio leads to a minimum prediction error. Experimental results for a 12-element detector array support the theoretical predictions.     

In Two Minds? — Parental Attitudes toward Physical Punishment in the UK

Since the Millennium, the use of physical punishment in the home has been a widely debated topic across the UK. Reliance on public opinion has been an important feature of this debate with a variety of UK surveys showing that many find physical punishment acceptable and do not support a complete ban on smacking. Drawing on the results from a comprehensive review of the literature, this article highlights that public/parental opinion is less than straightforward. Parents are often ambivalent about physical discipline, do not view it as an optimal method of behaviour management and are more prone to smack when stressed or angry. Likewise, a survey of the disciplinary practices and attitudes of 1000 parents in Northern Ireland shows that majority of parents have negative attitudes towards physical discipline. Nonetheless, many parents continue to smack despite the fact they do not believe it to be effective. Lack of parental support for legislative reform should be reconsidered in the light of this ambivalence. Most important, the UK Government needs to reframe the smacking debate in terms of children’s rights rather than relying on public opinion if it is to fulfil its commitment to protect children from harm as set out in the United Nations Convention on the Rights of the Child.     

Is Business Discourse Colonizing Philanthropy? A Critical Discourse Analysis of (PRODUCT) RED

Increasingly, traditional notions of philanthropy are colonized by a market discourse that promotes consumption as an effective way to solve social ills, resulting in what scholars have termed “marketized philanthropy.” This paper examines the implications of marketized philanthropy through a discourse analysis of the (PRODUCT) RED campaign benefiting the Global Fund to fight HIV/AIDS, malaria, and tuberculosis in Africa through consumption of (RED)-branded products. This paper explores the implications of a business-oriented model of philanthropy for bringing about social change, the repercussions of campaigns like (RED) that explicitly shed the label of philanthropy; and how they impact political engagement.
