Existing theoretical perspectives suggest that adolescents who are characterized by high achievement may experience social sanctions from peers. The central premise is that, in many North American settings, adolescent peer groups are characterized by negative attitudes toward the school environment. To test these hypotheses, we examined associations between indicators of low social power (unpopularity and victimization by peers) and academic competence for 415 adolescents (193 boys; 222 girls) attending an urban high school. This school served neighborhoods that were characterized by a moderate degree of economic distress and the students were predominately of Hispanic American descent. A short-term longitudinal design was used, with two waves of data collected over consecutive school years. The adolescents completed a peer nomination inventory assessing relational and overt victimization by peers, unpopularity, and social rejection. In addition, we obtained math and language arts grades from school records, and we assessed behavioral engagement in school with a self-report inventory. Structural equation models did not reveal a strong pattern of longitudinal change in social standing with peers or academic functioning. However, we found positive correlations between academic achievement and problematic peer relationships in both years of the project. We also found evidence that gender moderates these associations, with the effects reaching significance only for boys. Our results provide evidence that, in some settings, high achieving adolescents can be prone to negative treatment or marginalization by peers. 相似文献

- The Chicago Board Options Exchange's (CBOE) Volatility Index (VIX) is the premier established benchmark of near‐term market volatility. It is also referred to as the ‘investor fear gauge’ because it provides a consistent measure of market turmoil. We examine the VIX as it relates to Presidential popularity as indicated by the Gallup Organization's ongoing poll of US Presidential approval ratings. Our analysis indicates that the expected volatility of the market is highly related to Presidential approval. We then examine the strength and implications of this relationship in order to further establish the link between the economy and Presidential approval.

This article examines the compatibility between performance improvement and compliance‐based accountability in the implementation of a new system of public health performance management in Ontario. Findings from this mixed‐method study show that only minor elements of performance improvement get incorporated into pre‐existing compliance‐based accountability structures, that reinforcement of accountability structures works to the detriment of performance improvement intentions, and that limiting managerial influence in developing performance measures and targets diminish the utility of information for improvement. The study concludes that achieving a better balance requires an alternative to top‐down decision making that goes beyond consultation to include partnership. 相似文献

Assessing civil competence in the elderly. 总被引:1,自引:0,他引:1
This study was designed to establish reliability of the Community Competence Scale-Revised (CCS-R) and provide evidence for its validity in making discriminations relevant to civil competence in the elderly. The CCS-R is an individually administered structured interview of 17 subscales. Criterion groups were formed by drawing a sample of research participants from a retirement complex with various levels of care and with nurses having extensive knowledge of the residents' level of functioning. The study demonstrated high reliability and found converging evidence for the effectiveness of the CCS-R in making discrimination about competence in the elderly. The study had added to the growing evidence that it is possible to standardize the assessment of civil competence, thereby making the adjudication process a more accurate one. 相似文献

Thousands of barium enemas are performed in the United States each year without incident. Occasionally complications arise, only a few of which are fatal. Perforation is the most frequent serious complication of this procedure. Two instances of fatal perforation, one colonic and the other vaginal, are described, and the relevant literature is reviewed. 相似文献
