As part of an international public health partnership formed in 2001 we assessed the impact of Project Northland in Croatia--an adolescent alcohol school-based prevention intervention implemented in Split--on students. The curriculum was implemented in 13 randomly selected schools with another 13 schools serving as controls. The evaluation included quantitative and qualitative methods, using pre/post-tests to compare intervention and controls and follow-up focus groups with parents and teachers. Quantitative data showed the intervention was more successful in changing attitudes in the first two years, but had less impact on older students. Qualitative data suggest benefits from the program overall. Given the intervention was successful in the earlier grades it should be initiated earlier to have a greater impact. Challenges and lessons learned are offered.  相似文献

Infants are attuned to emotional facial and vocal expressions, reacting most prominently when they are exposed to negative expressions. However, it remains unknown if infants can detect whether a person's emotions are justifiable given a particular context. The focus of the current paper was to examine whether infants react the same way to unjustified (e.g., distress following a positive experience) and justified (e.g., distress following a negative experience) emotional reactions. Infants aged 15 and 18 months were shown an actor experiencing negative and positive experiences, with one group exposed to an actor whose emotional reactions were consistently unjustified (i.e., did not match the event), while the other saw an actor whose emotional reactions were justified (i.e., always matched the event). Infants' looking times and empathic reactions were examined. Only 18‐month‐olds detected the mismatching facial expressions: Those in the unjustified group showed more hypothesis testing (i.e., checking) across events than the justified group. Older infants in the justified group also showed more concerned reactions to negative expressions than those in the unjustified group. The present findings indicate that infants implicitly understand how the emotional valence of experiences is linked to subsequent emotional expressions.  相似文献

Abstract

The association of knowledge of health risks, living arrangements, and perceived stress with health-risk behaviors was examined in a sample of college students included in the Health Promotion and Disease Prevention Supplement of the National Health Interview Survey. Regressions of each health-risk behavior (dependent variable) were performed on the predicted correlates. Although knowledge was not associated with participation in physical activity or smoking, the study found that students who knew more about the harmful effects of alcohol drank less, and those with greater knowledge of health risks practiced fewer risky behaviors. Students living independently were more likely to smoke, and those living in residence halls were less like to do so. Drinking, however, was more common among students living in residence halls or independently than among those living at home. Hall residents engaged in more group physical activity than other students did, but their physical activity was unrelated to health-risk behaviors. Stress was associated with smoking but not with other health practices. The findings suggest that smoking may be less influenced by health knowledge and more associated than drinking is with a response to stress. Drinking appears to be a social activity associated with living among peers and is potentially modifiable by increased knowledge about the effects of alcohol on health.  相似文献

Abstract Instrustrial restructuring in the 1980s ushered in a new pattern of growing economic diversity over geographic space. The objective of this study is to examine the extent and etiology of changing spatial inequality between and within metropolitan (metro) and nonmetropolitan (nonmetro) areas, as measured by increasing or decreasing county poverty rates. Results based on data from the 1980 and 1990 census summary tape files suggest several conclusions. First, poverty rates increased more rapidly in nonmetro than metro counties during the 1980s; historical patterns of metro-nonmetro economic convergence slowed over the past decade. Second, poverty rates tended to decline in nonmetro counties with traditionally high rates of poverty, thus providing counter-evidence to arguments suggesting that the gap between traditionally poor and nonpoor nonmetro counties has widened. Third, spatial differences in poverty rates and relative increases in county poverty rates over the 1980s were most strongly associated with women's employment and headship status. The results raise questions about the extent to which traditional rural economic development strategies address the potentially deleterious economic effects of rising percentages of poor female-headed families.  相似文献

The stated UK Government policy on Higher Education is to attract increasing numbers of non‐traditional applicants to Higher Education. Mature students are positioned as key within this policy initiative. However, the statistics suggest that recent policy changes have made it more rather than less difficult for non‐traditional students to attend university. This paper explores some of the sociological and psychological processes which make working‐class transitions to higher education problematic by focusing on the narratives of 23 mature students attending an inner London Further Education college. It is argued that class, although mediated by gender and ethnicity, always counts in the transition process. Also, within the working‐classes there are different class fractions with differing priorities in relation to risk, challenge and fitting in. These solidarist and individualist fractions within the working‐classes result in differing priorities, attitudes and actions in relation to the higher education choice process.  相似文献

Public opinion about labor unions is influenced by a variety of factors, including media coverage. The type of media coverage unions receive provides a cognitive foundation for judgments about them and media coverage of unions has often been characterized as biased. This study examines media coverage of unions between 1946 and 1985 and shows that it became increasingly concentrated on strike activities and exaggerated the frequency of strikes. Moreover, strike-centered coverage has its strongest negative influence on individuals who lack ideological and group attachments to unions.  相似文献
