Adolescent suicide is increasing in the United States and the incidence of suicide gestures and attempts in juvenile correctional facilities is high. The attitudes of correctional staff toward adolescents and toward suicidal behavior may contribute to the increase. Suicide is often the outcome of a progression of problems that have isolated the adolescent from meaningful social relationships. Correctional staff must be aware of the phenomenon of adolescent suicide and be given training to deal with it effectively within the institution. Institutional staff have commonly seen suicide gestures or attempts as acting out behavior rather than a symptom of low self-esteem or inability to cope with institutional placement. This discussion examines the phenomenon of adolescent suicide and the impact the juvenile justice system has on its occurrence. It will also include an examination of interdisciplinary interventive strategies which can be used in an institutional setting.  相似文献

Voluntary sector organizations claim to be private institutions acting for the public good. However, if the concept of public is disengaged from the state and connected instead to citizenship, VSOs can be shown to have both private and public origins, as well as private and public impacts. As citizens, VSOs are public organizations serving the public good through their purported representation of the people and civic leadership. The legitimacy of their assumption of these public roles remains a continuing challenge.  相似文献

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.  相似文献

The problem of keeping abreast of relevant competitive developments for strategic purposes is common to many organizations. In this article the authors describe a system which they have developed and which is currently in operation which they believe can prove beneficial in meeting this need. They believe that their system provides competitive data in a useful form. Also it ensures that information, and not data, are processed and provided for planners and managers to support their decision-making.  相似文献

Abstract

Continuous shiftworkers of both genders who like shiftwork and report fewer digestive problems have higher scores on hardiness than those who dislike shiftwork. Whether this is a causal, consequential or accidental relationship requires a longitudinal investigation. It is also not clear how far ‘hardiness’ is a personality measure, a behavioural style, a coping strategy, or a consequence of the stress of shiftwork.  相似文献
