Puerto rican drug users’ experiences of physical and sexual abuse: Comparisons based on sexual identities

This study integrates the results of quantitative and qualitative methods to elucidate the association between sexual identity and physical and sexual abuse among Puerto Rican drug users. A structured questionnaire was administered to 800 subjects in New York and 399 in Puerto Rico. A total of 93 subjects (7.9%) self‐identified as homosexual or bisexual. Gay males were significantly more likely than heterosexual males to report first occurrence of physical abuse by a family member in childhood. Both gay and bisexual males were more likely than their heterosexual counterparts to report first experiencing unwanted sex in childhood and intimate partner physical abuse later in life. Lesbians were more likely than female heterosexuals to report unwanted sex in childhood. Qualitative data were collected through in‐depth life histories with 21 subjects and suggest that gay and lesbian subjects perceive antihomosexual prejudice on the part of family members as one cause of childhood physical and sexual abuse.     

Community Support of Ethanol Plants: Does Local Ownership Matter?*

Drawing on data from six communities in Kansas and Iowa, we explore the factors that are related to community members' current levels of overall support for local ethanol plants. What are residents' opinions about the benefits and drawbacks of local ownership of ethanol plants? How does that awareness lead to overall support of plants? Our interest is to understand how perceptions of the negative effects of the plant on the local infrastructure and environment and positive effects on the local economy influence the relationship between local versus absentee ownership and people's overall support of the plant. We use chi‐square to test whether respondents' overall support is associated with the ownership of the plant (local versus absentee), and cumulative logit mixed‐effects models to explore the factors that explain the association between ownership and overall support. Findings suggest that community members are less likely to show high support for locally owned plants, and that the greater perceived negative effects of locally owned plants on the local infrastructure and environment helps explain residents' lower support of locally owned ethanol plants in their communities. We posit several explanations for why this might be the case.     

Temporary Skilled Migration to Australia: Employers' Perspectives1

With the 1996 introduction of a new visa making it easier for employers to sponsor skilled foreign workers, temporary skilled migration has become a significant component of international migration flows to Australia. This paper examines employers' reasons for sponsoring skilled workers from abroad, their modes of recruitment, the occupational skills they require, and their industry profile. We also discuss issues relating to the perception of a shortage of skilled workers, the extent that sponsoring foreign workers substitutes for investing in local training, and the role of networks in recruiting overseas workers. Many employers' now have a global view of labour recruitment. While this is understandable for multinational companies with global operations, many small businesses and public sector institutions are adopting the same strategy to obtain skilled labour which they say is in short supply in Australia. With the internationalization of the Australian economy, there is also an increasing demand for people with specialized skills and knowledge that is not available in Australia's relatively small labour market. An understanding of the demand factors motivating temporary skilled migration is crucial to effectively managing Australia's migration and labour trends.     

A Push Toward Equality: Processes Among Dual‐Career Newlywed Couples in Collectivist Culture

This study examines gender construction among dual‐career newlywed couples in a collectivist culture. A qualitative analysis of in‐depth interviews with 20 heterosexual Singaporean couples reveals aspects of the collectivist norms (e.g., doing family, we‐consciousness, marrying one's equal) that are favorable toward the development of gender equality. Additionally, as couples respond to the political and social pulls of economic development, they begin to organize their relationship around both careers. Incorporating egalitarian values becomes a pragmatic move carried out through five direct processes: (a) career as central to the relationship, (b) flexible allocation of household duties, (c) open dialogue regarding conflict, (d) equal say in decision making, and (e) internal self‐reflection. Implications for future research are addressed.     

Violence Exposure and Drug Use in Central American Youth: Family Cohesion and Parental Monitoring as Protective Factors

Associations between witnessing serious violence and drug use, and the protective influences of family cohesion and parental monitoring, were investigated among 9,840 adolescents (50.5% female, M age=15.29 years, SD=1.76) living in Panama and Costa Rica. After accounting for demographics and parental and sibling substance use, witnessing serious violence was associated with greater drunkenness, tobacco use, number of illicit drugs used, and problems with drugs and alcohol. In every analysis, exposure to violence was associated with more drug use, while family cohesion and parental monitoring attenuated risk. Further, family cohesion and parental monitoring exerted a protective‐stabilizing effect on number of illicit drugs used and on problems with drugs and alcohol. There were few interactions with age. Implications for prevention are discussed.     

Perceptions of work stress in Australian firefighters

This study surveyed 747 firefighters on their perceptions of work stress. The current emphasis in the fire brigades is on the management of traumatic or critical incident stress, but other work stressors may also be important. The firefighters rated their jobs as more stressful than other occupations, and psychological work stress as highest among a set of potential sources and types of stress. Although many factors were mentioned, the most frequently indicated stressors were associated with exposure to traumatic incidents such as major accidents or the suffering of others. Those who had previous experience with stress were more likely to rate current and future risk of stress as higher. Knowledge of existing organizational approaches to stress management was limited. The firefighters rated individual and informal sessions for dealing with stress as potentially more useful than the formal debriefing sessions now common in many emergency organizatins. Those who had previous experience with stress, however, were more likely to favour a formal organizational approach.     

Modelling spatially correlated data via mixtures: a Bayesian approach

Summary. The paper develops mixture models for spatially indexed data. We confine attention to the case of finite, typically irregular, patterns of points or regions with prescribed spatial relationships, and to problems where it is only the weights in the mixture that vary from one location to another. Our specific focus is on Poisson-distributed data, and applications in disease mapping. We work in a Bayesian framework, with the Poisson parameters drawn from gamma priors, and an unknown number of components. We propose two alternative models for spatially dependent weights, based on transformations of autoregressive Gaussian processes: in one (the logistic normal model), the mixture component labels are exchangeable; in the other (the grouped continuous model), they are ordered. Reversible jump Markov chain Monte Carlo algorithms for posterior inference are developed. Finally, the performances of both of these formulations are examined on synthetic data and real data on mortality from a rare disease.
