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 size of the federal budget tells only one part of the tale of government's presence in the market economy. The enormous amounts of non-tax dollars government requires to be spent on regulation – estimated at $647 billion per year – powerfully argue for some sort of regulatory scorekeeping. Regulatory costs are equivalent to over one-third of the level of government spending. A regulatory budget can be an effective tool both for spurring reform and monitoring regulatory activity.At bottom, today's rulemaking process is plagued by the fact that agency bureaucrats are not accountable to voters. And Congress – though responsible for the underlying statutes that usually propel those unanswerable agencies – nevertheless can conveniently blame agencies for regulatory excesses. Indeed, Americans live under a regime of Regulation Without Representation.A regulatory budget could promote greater accountability by limiting the regulatory costs agencies could impose on the private sector. Congress could either specify a limit on compliance costs for each newly enacted law or reauthorization of existing law, or Congress could enact a more ambitious full-scale budget paralleling the fiscal budget, a riskier approach. A comprehensive budget would require Congress to divide to a total budget among agencies. Agencies' responsibility would be to rank hazards serially, from most to least severe, and address them within their budget constraint. In either version of a regulatory budget, any agency desiring to exceed its budget would need to seek congressional approval.Regulatory costs imposed on the private sector by federal agencies can never be precisely measured, and a budget cannot achieve absolute precision. Nonetheless, a regulatory budget is a valuable tool. The real innovation of regulatory budgeting is its potential to impose the consequences of regulatory decisionmaking on agencies rather than on the regulated parties alone. Agencies that today rarely admit a rule provides negligible benefit would be forced to compete for the right to regulate. While agencies would be free to regulate as unwisely as they do now, the consequences could be transfer of the squandered budgetary allocation to a rival agency that saves more lives.Budgeting could fundamentally change incentives. Under a budget, adopting a costly, but marginally beneficial, regulation will suddenly be irrational. Congress would weigh an agency's claimed benefits against alternative means of protecting public health and safety, giving agencies incentives to compete and expose one another's bogus benefits. Budgeting could encourage greater recognition of the fact that some risks are far more remote than those we undertake daily. In the long run, a regulatory budget would force agencies to compete with one another on the most important bottom line of all: that their least-effective rules save more lives per dollar spent (or correct some alleged market imperfection better) than those of other agencies.There are clear benefits to regulatory budgeting, but there are also pitfalls. For instance, under a budget, agencies have incentives to underestimate compliance costs while regulated parties have the opposite incentive. Self-correcting techniques that may force opposing cost calculations to converge are only at the thought- experiment stage. However, limitations on the delegation of regulatory power and enhancing congressional accountability can help.Certain principles and antecedents can help ensure that a regulatory budgeting effort succeeds. Explicitly recognizing that an agency's basic impulse is to overstate the benefits of its activities, a budget would relieve agencies of benefit calculation responsibilities altogether. Agencies would concentrate on properly assessing only the costs of their initiatives. Since an agency must try to maximize benefits within its budget constraint or risk losing its budget allocation, it would be rational for agencies to monitor benefits, but Congress need not require it.Other ways to promote the success of a budget are to: establish an incremental rather than total budget; collect and summarize annual report card data on the numbers of regulations in each agency; establish a regulatory cost freeze; implement a Regulatory Reduction Commission; employ separate budgets for economic and environmental/social regulation; and control indirect costs by limiting the regulatory methods that most often generate them.A regulatory budget is not a magic device alone capable of reducing the current $647 billion regulatory burden. Yet a cautious one deserve consideration. Having good information is an aid in grappling with the regulatory state just as compiling the federal fiscal budget is indispensable to any effort to plan and control government spending. 相似文献

American Indian researchers and scholars have emphasized the importance of identifying variables that promote resilience and protect against the development of psychopathology in American Indian youth. The present study examined the role of self-regulation, specifically goal characteristics (i.e., goal self-efficacy, goal specificity, intrinsic vs. extrinsic motivation, and goal conflict) and dispositional optimism, as well as cultural identity and self-reported academic grades in the depressive experiences of American Indian youth from a North American plains tribe. One hundred and sixty-four participants (53 % female) completed measures of goal representations, cultural identity, dispositional optimism, academic performance, and depressive symptoms. Results supported a model in which higher goal self-efficacy, American Indian cultural identity, grade point average, and dispositional optimism each significantly predicted fewer depressive symptoms. Moreover, grade point average and goal self-efficacy had both direct and indirect (through dispositional optimism) relationships with depressive symptoms. Our findings underscore the importance of cognitive self-regulatory processes and cultural identity in the depressive experiences for these American Indian youth and may have implications for youth interventions attempting to increase resiliency and decrease risk for depressive symptoms. 相似文献

Although most people in developed countries experience sexual initiation during adolescence, little is known about inter-country
variability in the psychosocial correlates of early initiation. Population-based samples of 15-year-olds (n = 6,111, 52% female) who participated in the Health Behaviors in School-Aged Children Study (Finland, Scotland, France and
Poland, 1997/1998) or the National Longitudinal Study of Adolescent Health (United States, 1996) self-reported sexual intercourse
experience and physical (headaches, trouble sleeping) or psychological (unhappiness, loneliness, sadness, moodiness) symptoms.
Analyses were conducted stratified by gender. Sexual initiation prevalence and symptoms scores varied significantly across
nations. In adjusted models, sexual initiation was not related to symptoms among boys in any nation, but significantly positively
related to symptoms among girls in Poland and the US. Results support variability by gender and nation in the relationship
between adolescents’ sexual initiation and physical/psychological symptoms. Empirically investigating specific features of
national contexts that generate these differences should be explored further. 相似文献

Little is known about the social networks of homeless youth in emerging adulthood despite the importance of this information
for interventions to reduce health risks. This study examined the composition of social networks, and the risks and supports
present within them, in a random sample of 349 homeless youth (33.4% female, 23.9% African American, 17.7% Hispanic) between
the ages of 18 and 24. Social network members who were met on the street were among the most likely to be perceived as engaging
in risky sex, as well as to engage in substance use with the youth. Youth were more likely to count on relatives and sex partners
for support compared to other network members, but they also were more likely to use substances with sex partners and perceived
them as engaging in risky sex. Interventions may need to recognize the importance of intimate relationships during the developmental
stage of emerging adulthood by enhancing supportive bonds and reducing substance use and risky sex in these relationships. 相似文献

Over the past few decades, a gender gap has emerged in the mass public in ideological self-placement. While most men and women
moved in the conservative direction, another segment of women retained their liberal self-identifications. A gender gap also
exists in how men and women define their ideology. Which issues are linked to ideological identities is conditioned by gender
and time period. Finally, ideological identities are structure by nonpolitical values as well as political issues. Religiosity
and religious beliefs have come to increasingly shape Americans’ ideological identities, with some differences across the
two sexes.
