Substance use among college athletes: a comparison based on sport/team affiliation

OBJECTIVE: Prior research shows that college athletes have higher rates of substance use, especially alcohol, than do college students who are not involved in athletics. To augment the literature, the author sought to determine which sports/teams are at the greatest risk for substance use. PARTICIPANTS: The author used data from the 1999 Harvard School of Public Health College Alcohol Study, a national survey of college and university students in the United States. METHODS: A series of chi-square and logistic regression models examined variation in substance use among college athletes on the basis of sport/team affiliation. RESULTS: Findings indicated that male hockey and female soccer athletes were the most likely to report substance use and that male basketball and cross-country/track athletes reported lower levels of substance use. CONCLUSION: There is variation in substance use on the basis of sport/team affiliation, and future researchers should examine why certain groups of athletes have higher rates of substance use.     

Osteoporosis knowledge and attitudes: a cross-sectional study among college-age students

OBJECTIVE: The authors' purpose in this study was to investigate the influence of knowledge of osteoporosis, attitudes regarding osteoporosis, and knowledge of dietary calcium on dairy product intake in both male and female college-age students. PARTICIPANTS: The authors conducted this cross-sectional study on 911 men and women enrolled in 2 demographically similar universities. METHODS: A modified osteoporosis knowledge questionnaire assessed participant's general osteoporosis knowledge and perceived disease risk. RESULTS: The authors found that knowledge of osteoporosis and calcium did not significantly influence dairy product intake. Attitude regarding osteoporosis was a significant predictor of dairy product intake in men but was not significant for the women. CONCLUSIONS: The authors recommend development and implementation of educational programs designed to increase awareness of calcium-rich food sources as well as other risk factors of this crippling disease.     

HIGHER EDUCATION AND CRIMINAL OFFENDING OVER THE LIFE COURSE

Educational attainment and school bonding are established predictors of delinquent behavior. In spite of an abundance of research on the relationship between education and delinquency, there is little research that examines the impact of education on stability and change in criminal offending over the life course. This dearth of research is surprising given the increasing significance of post-secondary education in contemporary society and the prominence of the life course approach in the study of crime. The current study uses seven waves of data from the National Youth Survey to examine the impact of higher education on criminal offending over the life course. Findings indicate that college attendance and investment in higher education are negatively associated with criminal offending in adulthood. In addition, the protective effect of higher education is stronger for individuals who were more delinquent during adolescence. Study limitations and future research needs are discussed.     

Information and ambiguity: herd and contrarian behaviour in financial markets

The paper studies the impact of informational ambiguity on behalf of informed traders on history-dependent price behaviour in a model of sequential trading in financial markets. Following Chateauneuf et al. (J Econ Theory 137:538–567, 2008), we use neo-additive capacities to model ambiguity. Such ambiguity and attitudes to it can engender herd and contrarian behaviour, and also cause the market to break down. The latter, herd and contrarian behaviour, can be reduced by the existence of a bid-ask spread.     

Nutrition and Fertility in Bangladesh: Breastfeeding and Post Partum Amenorrhoea

From 1975 to 1980 a prospective study a nearly 2,500 married, fertile women was conducted in Matlab, Bangladesh at the International Centre for Diarrhoeal Disease Research. Women were interviewed at monthly intervals to collect information on nutritional and reproductive status, in order to study the factors associated with natural fertility. The median duration of amenorrhoea for women with no child deaths was 15.5 months, with older women and those of higher parities recording longer durations than younger women or those of lower parities. Median duration of amenorrhoea for women with six or more years of education was 8.4 months compared to 16.4 months among women with no education. When classified by weight at pregnancy termination, average duration of amenorrhoea of women weighing less than 38 kg was 17.6 months compared to 13.6 months among women weighing more than 44 kg. Proportional hazards analyses show that mother's education, parity, month of birth, supplementation practices and nutritional status were significantly associated with the probability of resuming menstruation.     

Relationships between psychological,physical, and behavioural health and work performance: A review and meta-analysis

The relationships between health and job performance problems have received increased attention in business and scientific communities. This paper attempts to synthesize theoretical and empirical work in this arena. First, the theoretical links between health and work performance are presented. This is followed by a meta-analysis of the relations between psychological, physical, and behavioural health variables and work performance criteria. Meta-analytic results from 111 independent samples obtained from a search of the literature indicate that psychological health, in the form of psychological well-being, depression, general anxiety, and life satisfaction, is a moderate-to-strong correlate of work performance. Associations between physical health, particularly somatic complaints and hypertension, and performance were weak-to-moderate. Regarding health behaviour, alcohol consumption, and smoking were weakly and sleep problems moderately associated with performance problems. Effect sizes sometimes differed across performance dimensions and data sources. The results are consistent with the notion that ill-health is associated with substantial reductions in work performance. This implies that interventions to improve health may have an impact on performance. However, as most of the research in this area has been cross-sectional, more longitudinal research is needed to test theoretical and alternative causal explanations for the relations summarized in this review.     

Parental military service and adolescent well‐being: mental health,social connections and coping among youth in the USA

The association between parental military work factors and adolescent's well‐being was examined. Data were collected from 1036 military youth. Using a within‐group design, we examined adolescent's well‐being related to parental absence, school and neighbourhood transitions, paygrade/rank and participation in military‐sponsored activities, and differentiated outcomes by sex and age. Two parental work factors primarily influenced adolescent's well‐being, parental paygrade/rank and engagement in military‐sponsored activities. Parental paygrade/rank was the only factor uniformly related to poorer well‐being, and this variable likely represents a more complex set of family circumstances. Engaging in military‐sponsored activities served as a resource and was related to enhanced well‐being. Individual‐level differences and implications for social workers are discussed.     

Get It Now: Five Years Later

Abstract

Five years ago, Tennessee Technological University Library implemented the use of Get It Now from the Copyright Clearance Center to provide their users with instant access to journal articles. Funding for this initiative came from the cancellation of expensive ejournal packages. Examining implementation, usage, costs, and pros and cons is helpful for other libraries considering this method of document delivery.     

Social Entrepreneurship Through an Organizational Ecology Lens: Examining the Emergence and Evolution of the Voucher School Population in Milwaukee

The creation and introduction of new ideas and new organizations to address social challenges are central features in current social entrepreneurship research, and over the past two decades scholars have proposed a variety of approaches to understand and analyze these and other dimensions of social entrepreneurship. This article looks at social entrepreneurship from an ecological perspective and proposes that organizational ecology has much to offer this emerging filed. Specifically, the article draws from a unique dataset on voucher schools in Milwaukee, Wisconsin to analyze the emergence as well as dynamics of this nonprofit population.
