Analytic approaches to problems of a middle-sized defence department

The application of operational research to the problems of Canadian defence was very similar to that in Great Britain and the United States during World War II and through the 1950s. But because of the rapidly increasing costs of major weapon systems, since the 1960s systems analysis has been very thoroughly applied to the study of the large procurement programs, including far-reaching examination of their economic impact on the nation. Other problems of special interest to Canada which received analytical attention included peacekeeping and military involvement in activities such as maritime surveillance and search and rescue. Analytical studies have been extended into examination of logistics and manpower, and into economic, sociological, and strategic problems of concern to the Canadian defence department, including arms control. This type of research represents a considerable excursion from the original operational research, but is needed in the Canadian Department of National Defence.     

Performance evaluation of normal distribution software

Methods are developed to test the performance of software for calculating the standard normal distribution function. The accuracy and implementation details of the tests are described. Results are presented on a selection of available codes, showing a wide variation in performance. At least one published code is shown to have severe defects.     

Insiders or Outsiders: normalisation and women with learning difficulties

This paper examines changing attitudes towards women with learning difficulties within the culture of normalisation. It builds on earlier critiques of the normalisation principle and, whilst welcoming these, argues the case for looking at women in particular. The authors review literature on sex education for people with learning difficulties to illustrate the ways in which gender has been ignored and women's sexuality has been treated. Writing from their perspective as lesbian feminists, they explore the oppressive nature of sex education in a culture that places a premium on normality. The paper ends with a discussion of alternative ways for women with learning difficulties to gain a sense of identity and belonging.     

Influencing alcohol control policies and practices at community festivals

The goal of this study was to assess the feasibility and effectiveness of two interventions aimed at reducing alcohol-related risks at community festivals--a training program for festival planners and a community organizing campaign. We randomly selected four festivals for each intervention and had 24 comparison festivals. Our assessment included process evaluation to track and evaluate types of alcohol policies resulting from each of the interventions, pre and post telephone surveys of key festival planners and law enforcement agencies, and pre and post pseudo-underage and pseudo-intoxicated purchase attempts. Analyses showed that both interventions were feasible and were successful in influencing adoption of written policies and improving alcohol-related practices. However, neither intervention appeared to decrease propensity for illegal alcohol sales at these events, likely due, in part, to the short time frame of the interventions. Future research should assess effects of the interventions on alcohol-related problems and effects of enforcement interventions.     

Promising research and methodological approaches for health behavior research with homeless persons

High-risk health behaviors have high prevalence among homeless persons prompting substantial research on health behavior and behavior change strategies within the population. Previously, much of this research focused solely on the target behavior without consideration of contextual factors that may contribute to the behavior or that may inhibit behavior change. We describe three overlapping trends in homeless health behavior research – longitudinal, qualitative, and participatory – which consider the link between the context of homelessness and health behavior. These approaches contribute to the understanding of the social determinants of health behavior and health and demonstrate opportunities for intervention beyond the individual level.     

Exploring the Association Between Dispositional Cancer Worry,Perceived Risk,and Physical Activity Among College Women

Abstract

Objective: In this study, the authors explored the association between dispositional cancer worry (DCW), risk perceptions (RP), and physical activity (PA) among college females. Participants: Four hundred fifty-one females from a midwestern university completed an online survey in September/October 2012. Methods: DCW severity, DCW frequency, RP, and PA were measured along with qualitative data about PA as cancer prevention. Results: Sixty-nine percent of participants did not meet PA recommendations. DCW severity was a significant predictor of meeting PA recommendations (odds ratio = 1.2, 95% confidence interval [1.00, 1.38]; p = .05). Qualitative data revealed a lack of knowledge about breast cancer risk and PA as cancer prevention. Conclusions: College women do not engage in enough PA nor feel at risk for developing breast cancer. A lack of knowledge exists about the cancer prevention benefit of PA. Results indicate a need for PA interventions that both educate breast cancer risk and motivate health protective behaviors.
