Objective. This research explores the seldom‐addressed question of whether teacher‐student racial congruence conditions the impact of teacher perceptions on performance. Methods. Multipopulation LISREL models (utilizing data from the NELS) compare the effect of white teachers' perceptions on African‐American standardized test performance to the corresponding effect among white students. Parallel models compare the impact of African‐American teacher perceptions across races. Preliminary models gauge whether the match/mismatch of teacher's and student's race shapes teacher perceptions of African‐American and white students. Results. The impact of teachers' perceptions on test performance shows signs of being especially pronounced in the racially dissonant white teacher‐black student context—the very context where teacher perceptions seem especially likely to be unfavorable. Conclusions. This research provides new insight on the relevance of teacher perceptions to the black‐white performance gap. Racial congruence seems primarily consequential to African‐American test performance—shaping both teacher perceptions and (somewhat less so) the impact of such perceptions on performance.  相似文献

The growing relative number, the improved economic well-being, and the migration of elderly retirees is not only reshaping the social and economic structure of many areas, it is also modifying both long-term and short-run patterns of economic growth. Transfer payments and property incomes, two of the most important source of elderly income, have been among the leading sources of national income growth over the past several decades. Unlike most labor-related industry sources of earnings, the level of transfer payments and property incomes received by the residents of the region is not directly dependent upon local economic activity. Consequently, as transfer payments and property incomes of elderly retirees become increasingly important sources of income and purchasing power within a region, they also can alter regional short-run cyclical patterns of income growth. This article examines the pattern of growth of transfer payments and property incomes in the context of national economic cycles, and explores the implication of those findings on metropolitan and nonmetropolitan Nevada economies.  相似文献

The authors consider dimensionality reduction methods used for prediction, such as reduced rank regression, principal component regression and partial least squares. They show how it is possible to obtain intermediate solutions by estimating simultaneously the latent variables for the predictors and for the responses. They obtain a continuum of solutions that goes from reduced rank regression to principal component regression via maximum likelihood and least squares estimation. Different solutions are compared using simulated and real data.  相似文献

Affective reactions to the departure of work group leaders are proposed as an important determinant of members' trust-related judgments regarding new leaders. A field test of veterinary hospital employees evaluating new leaders revealed that the affective reaction to the departure of the prior group leader predicted trust when there was no history between the individuals. When there was history between the two individuals, the group member's evaluation of the new leader's ability on their prior job was a significant predictor of trust over and above their affective reaction to the succession. The relationships between affective reactions to succession and trust formation were replicated in a longitudinal simulation of trust formation in student groups. The implications of these findings for the study of trust in organizations and leadership succession processes in work groups are discussed.  相似文献

Costa Rica in the 1930s had a level of social development typical of a peripheral society, yet today Costa Ricans enjoy a level equivalent to the wealthier US and Italy. This paper examines the contribution of labor to state formation and social development. Beginning around the First World War, labor gradually forced the adoption of social legislation that altered the distribution of social power and reshaped the ideological and institutional character of the state. Reactions to the increasing power of labor and the state culminated in the 1948 social pact among labor, the middle strata and the dominant class that institutionalized the existing ideological and strategic trends responsible for the present level of social development.  相似文献

This investigation compares school outcomes for students who differ in the extent to which they perceive their parents, friends, and teachers—each alone and in combination—as important sources of social support. Findings indicate that middle and high school students who perceive high supportiveness from all three sources of support, as opposed to none, one, or two, have better attendance; spend more hours studying; avoid problem behavior more; have higher school satisfaction, engagement, and self-efficacy; and obtain better grades. Positive school outcomes are promoted when teacher support is perceived in combination with perceived support from parents and friends. Implications of the results for human service providers are presented.  相似文献

Relationships between broadcast advertising exposure and variouscognitive and affective orientations were assessed in a surveyof voters during a congressional election campaign. Exposurewas moderately correlated with political knowledge and interest.Highly exposed voters were somewhat more likely to attach higheragenda priorities to issues and candidate attributes emphasizedin the commercials. Personal affect toward each candidate wasmildly associated with advertising exposure frequency.  相似文献

The recent trend of immigrants arriving in mid-size metropolitan areas has received growing attention in the literature. This study examines the success of immigrants in the housing markets of a sample of 60 metropolitan areas using Census microdata in both 2000 and 2005. The results suggest that immigrants are less successful in achieving homeownership and more likely to live in overcrowded conditions than native-born whites of non-Hispanic origin. The immigrant effect on homeownership differs by geography and by immigrant group. Finally, we find evidence that immigrant networks increase the likelihood of becoming a homeowner.  相似文献
