This study examines the structural relationships among depression, suicidal ideation, gateway substance use (including cigarettes, alcohol, and marijuana), and hard substance use (including cocaine, stimulants, and inhalants) in a sample of continuation high school students at high risk for drug abuse. When the model was examined separately by ethnic group (Latino and Caucasian) and gender, significant differences among the factor correlations emerged. Compared to Latinos and females, Caucasians and males, respectively, demonstrated a greater number of significant relationships among the factors. For Latinos and females, only the depression and suicidal ideation factors were significantly correlated with each other, as were the gateway and hard substance use factors. For Caucasians and males, four of the six factors were significantly intercorrelated. One implication is that mood enhancement may be a particularly important reason for hard substance use among Caucasian and male adolescents.  相似文献

The structural relationships among risk and protective factors were examined in a sample of 646 continuation high school students. Although depression predicted more perceived stress, it was not a unique predictor of anger coping, seeking social support, or substance use. Perceived stress increased seeking social support. Seeking social support decreased the utilization of anger coping, which suggests that it may be a means of prevention for adolescents. Anger coping behaviors were implicated as being significant in sustaining depression and perceived stress, and in increasing hard drug use over time. Moderation analysis indicated that although there was no difference in the stress–coping–depression relationship between Latinos and Caucasians, the relationship among perceived stress, anger coping, and depression was stronger for female than for male adolescents. Theoretical and practical implications of the findings are discussed.  相似文献

This piece provides a detailed case study of the evolution of counter-terrorism within a specific domestic security agency of a liberal-democratic state in the context of the Cold War. It does so by examining the creation of a counter-terrorism unit within Canada’s Royal Canadian Mounted Police Security Service and how it responded to international terrorism. This occurred in between major terrorist attacks in Canada in 1970 and 1985 and included a growing focus on counter-terrorism even as counter-subversion remained a top priority within a still dominant Cold War domestic security framework. Ultimately, the article, based on thousands of pages of previously secret documents, argues that the Security Service could conceive of in a broader strategic sense the threat of terrorism but found it more challenging, for a variety of reasons, including the dominance of the Cold War and the difficulties around infiltrating ethnic communities, to collect intelligence.  相似文献

This article explores how a devolved government in a small country, faced with external constraints beyond its immediate control, can deploy policy resources to shape a distinctive approach to public services. We analyse recent homelessness policy in Wales using the NATO (Nodality, Authority, Treasure, Organisation) typology of tools of government proposed by Hood and Margetts, and show how this can be applied usefully to understand the choices that governments must make in conducting relationships with other institutions. We conclude that a combination of Nodality and Authority provide powerful resources for a subnational government which has only limited formal powers and fiscal autonomy.  相似文献

This article is a response to an article written by William Howe and Hugh McIsaac that questions their recommendations that court‐based mediation not be used when certain types of persons appear in court. We assert that it will be very difficult for the court to identify these people. Further, we argue that mediation practice has advanced so far that even these persons (those with serious issues of domestic violence, substance abuse, and mental health) should be given an opportunity to participate in mediation before being referred to the adversarial court process.  相似文献
