School dropout and injecting drug use in a national sample of white non-Hispanic American adults

In this study we sought to extend our previous finding of an association between school dropout and injecting drug use (IDU) among African Americans by testing the association in a sample of White non-Hispanic Americans. A nationally representative sample of White non-Hispanic Americans age eighteen years and older was drawn from public use data files of the 1995-1996 National Household Surveys on Drug Abuse (NHSDA). Adults with a self-report history of IDU were identified, and were matched to non-IDU adults in the same neighborhoods of residence. Conditional logistic regression was used to estimate the association between dropping out of high school and the occurrence of IDU. White non-Hispanic American high school dropouts were more likely than high school graduates to have injected a drug at least once. The findings of this research on non-Hispanic Whites are generally consistent with our earlier evidence on the association between educational status and a history of IDU among African-American adults. School dropout prevention programs may merit attention in an overall strategy of preventing injecting drug use and HIV/AIDS.     

Evaluation of a family-based substance abuse prevention program targeted for the middle school years

A family-based substance abuse prevention program was evaluated which emphasizes family cohesion, school and peer attachment, self-esteem, and attitudes about adolescent use of alcohol and tobacco. The program was implemented in rural communities and targeted families with students entering middle or junior high school. Baseline surveys were conducted with students and parents in four schools and were readministered one year later. Because the program was voluntary, a quasi-experimental design was used to compare participants (29 students and 28 parents) and nonparticipants (268 students and 134 parents). Analyses of covariance indicated that student participants, as compared to nonparticipants, had higher family cohesion, less family fighting, greater school attachment, higher self-esteem, and believed that alcohol should be consumed at an older age at the one year follow-up. There were fewer significant results for parent participants. Strategies for involving parents in prevention programs are discussed.     

Boater training, drinking and boating, and other unsafe boating practices

OBJECTIVES: Identify associations between lack of formal boater training, drinking and boating, and other unsafe boating practices. METHODS: A telephone survey queried respondents (age 16 or older in continental United States) about boating experience, type of boat used, and training. RESULTS: Of the 3,042 boaters surveyed (70% response), most had no formal training (73%). Boaters with formal training failed to use PFDs about as often as those without formal training and were equally or more likely to use alcohol while boating. CONCLUSIONS: The unexpected association between formal training and unsafe boating practices is probably due to reduced risk perception and inadequacies of boater training programs. Such programs seldom mention the risks of alcohol use while boating. Decisions to mandate formal training should be informed by these results; if mandated, training should address the risks of alcohol use while boating, and should be renewed frequently enough to offset reductions in risk perception.     

Psychopathology and behavioral problems in mental retardation

1. The lack of psychiatric services for the mentally retarded is of particular concern for advanced practice nurses in psychiatry. 2. Prevalence of psychopathology and behavioral problems in the mentally retarded appears to be significant. 3. For purposes of diagnostic clarity, a thorough mental status and neurological examination specifically devised for the mentally retarded population must be utilized.     

Technology and managing people:

conclusion The Information Age has revolutionized the workplace. While it is possible to purchase or copy machines and technology, their very interchangeability means they fail to cre-ate a sustained competitive advantage for an organization (Barney, 1991). The research directions this paper offers are intended to develop firm knowledge that allows creation of inimitable human resources. Importantly, in the rush to embrace new information technologies, organizations must remember the fundamental principle that workers will invest in firm goals in the presence of shared values and a commitment by the firm to make their well-being a priority. We urge continued attention to fulfillment of the psy-chological contract, and to the "people issues" that frequently seem less critical than issues of hardware or technology.     

Profiles of refugee and non-refugee Palestinians from the West Bank and Gaza

Relying on demographic and labour surveys which the Palestinian Central Bureau of Statistics collected in 1995, this article investigates the profile of West Bank and Gaza refugees. Refugees are better educated and have higher fertility than non-refugee Palestinians, but the difference is small. However, they have a significantly lower participation rate, a higher unemployment rate and a higher incidence of arrests and work stoppage than the corresponding rates among non-refugee Palestinians. A smaller proportion of Palestinians commute to work into the Israeli labour market and refugees earn lower wages than non-refugees. Returns to investment in education are small for both groups. High fertility among refugees imposes a future challenge for policy makers in terms of resources required for the provision of appropriate education and health facilities. Employing future labour market entrants is another serious policy challenge.     

Mapping child maltreatment: looking at neighborhoods in a suburban county

This study used administrative data, census data, and geographic information system (GIS) technology to map and analyze the rates and distribution of child physical abuse, sexual abuse, and neglect at the neighborhood level in a suburban jurisdiction. The results provide an example of how administrative data, census data, and GIS technology can give child protective services and community-based agencies a visual tool to help identify and target neighborhoods in which children may be at high risk for maltreatment.     

Receiving shadows: governance and liminality in the night-time economy

This paper focuses upon the emergence of the night-time economy both materially and culturally as a powerful manifestation of post-industrial society. This emergence features two key processes: firstly a shift in economic development from the industrial to the post-industrial; secondly a significant orientation of urban governance involving a move away from the traditional managerial functions of local service provision, towards an entrepreneurial stance primarily focused on the facilitation of economic growth. Central to this new economic era is the identification and promotion of liminality. The State's apparent inability to control these new leisure zones constitutes the creation of an urban frontier that is governed by commercial imperatives.     

Decompositions of λ K v

In a series of 2 papers, Kang, Du and Tian solved the existence problem for G-decomposition of λ K _n when G is any simple graph with 6 vertices and 7 edges, except when G is the graph T=K ₄∪K ₂. Notice that a T-decomposition can be considered to be a Pairwise Balanced Design in which each block of size 4 has been matched to a block of size 2. In this paper we remove this exception for all λ≥2. The case when λ=1 is also addressed. This paper is written in honor of Frank Hwang on the occasion of his 65th birthday.
