The transition to high school has been identified as a potentially difficult time in adolescents’ lives. Reductions in both
academic and social functioning often accompany this transition. While these effects have been documented in urban youth,
the move to high school has not been extensively studied in rural minority youth. Toward that end, the academic grades and
substance use in ninth grade of 447 (184 male and 263 female) African-American adolescents from two rural counties in a state
in the deep South were examined in relation to configurations of adaptation from sixth through eighth grade. Results indicate
that individual with consistently positive patterns across middle school had higher grades and lower rates of substance use
compared to individuals with persistent difficulties or those that transitioned to problem behavior. Many individuals who
improved in their patterns of adaptation had relatively high grades, but also rather high rates of substance use in the ninth
grade.

In this article I test two competing visions about how democracy produces responsive government. Electoral theories of democracy posit that elected governments are responsive to public demands because citizens are able to sanction bad politicians and select good ones. Participatory theories attribute responsiveness to a citizenry's ability to articulate demands and pressure government through a wider range of political action. I test hypotheses derived from these two approaches, using an original dataset that combines electoral, socioeconomic, and public-financial indicators for Mexico's 2,400 municipalities, from 1989 to 2000. The data show that electoral competition has no effect on municipal government performance. But the results are consistent with the hypothesis that nonelectoral participation causes improved performance. Thus, I suggest that the quality of municipal government in Mexico depends on an engaged citizenry and cooperation between political leaders and their constituents, rather than the threat of electoral punishment. I recommend that scholars broaden the study of government responsiveness to account for participatory strategies of political influence and critically assess the claims of those who would promote elections as a cure-all for poor democratic performance. 相似文献

Why does the influence of Congressional parties fluctuate over time? Building on prevailing answers, we develop a model, Strategic Party Government, which highlights the electoral motives of legislative parties and the strategic interaction between parties. We test this theory using the entire range of House and Senate party behavior from 1789 to 2000 and find that the strategic behavior of parties complements members' preferences as an explanation for variation in party influence. Specifically, the strongest predictors of one party's voting unity are the unity of the opposing party and the difference between the parties in the preceding year. Moreover, we find strong links between party behavior in Congress and electoral outcomes: an increase in partisan influence on legislative voting has adverse electoral costs, while winning contested votes has electoral benefits. 相似文献

This study compared AIDS knowledge and attitudes in public high school students (N=167), incarcerated delinquents (N=166), and emotionally disturbed (SED) adolescents (N=151). The response measure was a 50-item Acquired Immunodeficiency Syndrome (AIDS) questionnaire that was previously used by Bell et al., in their 1991 study of learning disabled adolescents. Although AIDS knowledge was moderately high in all three groups, widespread misunderstandings about disease transmission and awareness of high-risk groups and practices were noted. Knowledge scores were significantly higher in the public school sample than in the SED adolescents; moreover, they tended to be slightly higher (p<0.10) than the delinquent group as well. Teenagers with the severest emotional problems were by far the least informed. Age and race were also predictive of AIDS knowledge. Other results showed that delinquents were more permissive in their attitudes about sex, more inclined to disdain safe sex practices, and more likely to feel threatened by high-risk groups as well as powerless to protect themselves against AIDS. Generally speaking, the findings extend the work of other investigators on the needs for AIDS education in adolescents. The need is especially urgent in delinquent and emotionally disturbed youth who may require a more comprehensive intervention because of their greater knowledge deficits, propensity for high-risk practices, and tendency to deny or underestimate their own vulnerability.Received Ph.D. in clinical psychology from the University of Utah in Salt Lake City.

Given that government budgets are increasingly stretched in the face of competing demands, there is a pressing need for evidence on the costs and benefits of public sector investments. Nowhere is this need greater than in the health field, where the benefits of programmes are typically difficult to measure. Within the health sector a key area of interest is primary health care, which is generally regarded as a central function and the most important means by which the health of the population can be improved. This paper reports the results of a recent survey of Commonwealth countries which sought to establish the extent of economic evaluation of PHC programmes, the impact on decision-making and the level of health economics expertise available in Third World countries. Based on the results of the survey, suggestions are made for improving the commissioning and conduct of economic evaluations, for interpreting and implementing evaluation results, and for developing government expertise in economic evaluation. 相似文献

Globalization critics argue that international trade spurs a race to the bottom among national environmental standards. ISO 14001 is the most widely adopted voluntary environmental regulation which encourages firms to take environmental action beyond what domestic government regulations require. Drawing on a panel study of 108 countries over seven years, we investigate conditions under which trade linkages can encourage ISO 14001 adoption, thereby countering environmental races to the bottom. We find that trade linkages encourage ISO 14001 adoption if countries' major export markets have adopted this voluntary regulation. 相似文献
