Conventional Ties,Peer Influence,and the Fear of Apprehension: a Study of Adolescent Marijuana Use*

This study examines the relationship between a belief in the certainty of apprehension and self-reported marijuana use; the relative importance of this belief and ties to conventional others as sources of control; and the extent to which involvement with other users is related to the belief examined and use. The findings suggest that both the belief examined and conventional ties, in this case to the family and school. serve as independent sources of control among the high school youth studied. Of particular importance is involvement with other users; use is unlikely given the absence of group supports. This holds both for youth who maintain conventional ties and for those with weak ties. Further, involvement with nonusing peers is related to patterns of use as well as the belief that one will get caught should he try. The effectiveness of the law as a deterrent, then, is questionable given peer involvement and reinforcement for beliefs which effectively discount or support the certainty of apprehension as a viable reason for nonuse.     

Perceptions of domestic abuse in same-sex relationships and implications for criminal justice and mental health responses

Male and female university students (N = 171) read scenarios describing a domestic abuse incident that systematically varied the sex of victim and perpetrator to produce four between-participants conditions. Results were consistent with and extended previous findings about perceptions of heterosexual domestic abuse to include gay and lesbian domestic abuse. Findings suggest that participant perceptions of abuse in same-sex and heterosexual relationships are similar. Where they differ, the differences have significant implications: (a) participants considered male against female abuse to be more serious than same-sex domestic abuse, (b) participants were more likely to recommend that the victim press charges in male against female abuse than in same-sex domestic abuse, (c) participants perceived same-sex victims to be less believable than heterosexual victims, and (d) victim believability was correlated with sentencing recommendations. Implications for criminal justice and mental health intervention are considered. Directions for future research are outlined.     

Estimating the costs of substance abuse: implications to the estimation of the costs and benefits of gambling

This presentation describes a recently developed set of guidelines for estimating the economic costs of substance abuse, summarizes the findings from a Canadian study that utilized these guidelines, and discusses the implications to the potential development of guidelines for estimating the costs and benefits of gambling. The guidelines for estimating the costs of substance abuse present a general framework of costs to be included and discuss methodological issues such as the definition of abuse; determination of causality; comparison of the demographic and human capital approaches; the treatment of private costs; the treatment of nonworkforce mortality and morbidity; the treatment of research, education, law enforcement costs, the estimation of avoidable costs and budgetary impact of substance abuse, and the significance of intangible costs. Utilizing these guidelines, a study was undertaken to estimate the economic costs of alcohol, tobacco, and illicit drugs to Canadian society in 1992. Based on this experience, it is argued that cost/benefit research should be conducted by multidisciplinary teams, that the real value of such work lies more in the detailed findings than in the bottom line results, and that focus should be placed on developing an ongoing process for developing consensus on how to conduct studies of the costs and benefits of gambling, rather than attempting to find a precise methodology that everyone agrees upon.     

The Two Faces of Toxic Waste: Trends in the Spread of Environmental Hazards

Data from the Massachusetts' Department of Environmental Protection (DEP) and the U.S. Census indicate that the toxic waste crisis is worsening. In addition to the contamination of deindustrialized urban areas comes increasing contamination in many newly industrialized suburbs. This results in both race and class biases with disproportionate amounts of toxic waste in urban communities of color and working-class (predominantly white) suburbs. Despite these region-specific associations, new evidence indicates that the single best indicator of toxic hazards, before controlling for region, is the percentage of community taxes from commercial and industrial sources. This raises important questions regarding sources of race and class biases and how to assess environmental injustices.     

A Note on the Protomental System and “Groupishness”: Bion's Basic Assumptions Revisited

In identifying the unconscious basicassumption behavior of groups, Bion made asignificant discovery. Although he toyed with explainingthis behavior as instinctive, he ultimately postulatedthat it was a postnatal defense. However, there is astrong case for the biogenetic explanation. Thissharpens our understanding of some group andorganizational processes that have been hithertodescribed in terms of psychoanalytic concepts. It may also haveimplications for management of, and interventions in,groups and larger systems.     

When do simpler sexual behavior data collection techniques suffice? An analysis of consequent uncertainty in HIV acquisition risk estimates

The "gold standard" for evaluating human immunodeficiency virus (HIV) prevention programs is a partner-by-partner sexual behavior assessment that elicits information about each sex partner and the activities engaged in with that partner. When collection of detailed partner-by-partner data is not feasible, aggregate data (e.g., total numbers of partners and acts of various types) must suffice. Lack of specificity in the primary data often translates into uncertainty in modeled outcomes, such as participants' risk of HIV acquisition. To our knowledge, no previous study has attempted to quantify this uncertainty. The results of the present analysis of the risk of HIV acquisition by men vacationing in Key West indicate that the use of aggregate rather than partner-by-partner data introduced relatively little uncertainty into the HIV risk estimates. Collection of aggregate data is a viable alternative to detailed partner-by-partner data, at least in some circumstances.     

Solution-focused group therapy for level 1 substance abusers

The present study compared solution-focused group therapy (SFGT) with a traditional problem-focused treatment for level 1 substance abusers. Outcome research on the effectiveness of solution-focused group therapy is minimal, especially in treating substance abusers. In the present study, clients were measured before and after treatment to determine therapeutic effectiveness. Clients in the solution-focused group significantly improved on both the Beck Depression Inventory and the Outcome Questionnaire. The clients in the comparison group did not improve significantly on either measure. Therapist skill level and adherence to theoretical models were measured in each group to reduce confounding variables.     

A QMRA for the Transmission of ESBL‐Producing Escherichia coli and Campylobacter from Poultry Farms to Humans Through Flies

The public health significance of transmission of ESBL‐producing Escherichia coli and Campylobacter from poultry farms to humans through flies was investigated using a worst‐case risk model. Human exposure was modeled by the fraction of contaminated flies, the number of specific bacteria per fly, the number of flies leaving the poultry farm, and the number of positive poultry houses in the Netherlands. Simplified risk calculations for transmission through consumption of chicken fillet were used for comparison, in terms of the number of human exposures, the total human exposure, and, for Campylobacter only, the number of human cases of illness. Comparing estimates of the worst‐case risk of transmission through flies with estimates of the real risk of chicken fillet consumption, the number of human exposures to ESBL‐producing E. coli was higher for chicken fillet as compared with flies, but the total level of exposure was higher for flies. For Campylobacter, risk values were nearly consistently higher for transmission through flies than for chicken fillet consumption. This indicates that the public health risk of transmission of both ESBL‐producing E. coli and Campylobacter to humans through flies might be of importance. It justifies further modeling of transmission through flies for which additional data (fly emigration, human exposure) are required. Similar analyses of other environmental transmission routes from poultry farms are suggested to precede further investigations into flies.     

Masculinities and sexualities in sport and physical cultures: three decades of evolving research

This article traces the foundation of the study between sport and physical cultures and masculinities and sexualities principally by examining the homophobic zeitgeist by which the academic discipline was formed. I show that the intense homophobia of the mid-1980s waned throughout the 1990s, and that during the new millennia, researchers found more inclusive forms of heterosexuality. Indeed, research on masculinities and homophobia today shows that, even in the traditionally conservative institution of sport, matters have shifted dramatically. This has resulted not only in improved conditions for sexual minorities, but it has also promoted a culture of softer, more tactile and emotional forms of heterosexual masculinities. These studies, alongside those within this special issue of the Journal of Homosexuality, highlight the necessity of developing new ways of theorizing the changing dynamics between masculinities, sexualities, and physical cultures in the next decade.
