To expand the scant research on sexual expectancies development among non–sexually active adolescents, we examined the relationship between adolescents' exposure to four socializing agents—mother/female guardian, father/male guardian, peers, and television programs with high sexual content—and their endorsement of four sexual expectancies: social benefit, pleasure, social risk, and health risk. Data are from Waves 2 and 3 of a three-wave annual longitudinal study conducted among California adolescents, the majority of whom were not sexually active (N = 914, 84%). Structural equation models were conducted to examine cross-sectional and longitudinal associations between the socializing agents and the sexual expectancies. Cross-sectional results indicate associations between peer sexual communication and social benefit, pleasure, and social risk expectancies. A positive association was found between exposure to music videos and social benefit expectancies, and a negative association was found between exposure to music videos and health risk expectancies. Longitudinal results suggest that communication with peers positively predicted pleasure expectancies and negatively predicted social risk expectancies. No other socializing agents were associated with any sexual expectancies. An invariance test found that significant correlations were similar across the different age groups. Results suggest that efforts to support positive sexual decision making among non–sexually active adolescents should target peer sexual communication. 相似文献

Previous research suggests that minorities are more likely to perceive racially-based discrimination in a variety of settings
than are whites, in large part because of the ways their personal experiences with racism shape the lens they use to view
the world. We examine a labor market that is typically considered an exception to patterns of racism in employment, the industry
of professional football. We interview athletes who attempted to gain employment in the National Football League, a labor
market where access to valued positions is heavily restricted by industry practices. Findings from field research and semi-structured
interviews indicate that minority workers experience symbolic discrimination during the hiring process. Differential treatment
of players reflects stereotypes about minority families and masculinity. Although minority and white players describe much
of the actual content of their labor market experiences in similar fashion, their perceptions of these experiences differ
sharply, with minority athletes identifying far more negative repercussions.

In this paper correlation has been introduced between two successive transitions in the model investigated by Moyal and Heathcote (1959). The transition rate has been taken to be constant and for simplicity of mathematical expressions the time scale has been so chosen that this rate is unity. For the unrestricted walk we find that the mean position of the particle at time t is that position for which the probability of the particle arriving at some earlier instant from the left is 1/2. With both the barriers either absorbing or reflecting, we have obtained the Laplace Transform of the distributions, but because of the complicated nature of the mathematical expressions involved we are able to find only the asymptotic distributions. For the reflecting barrier case, we find that the process tends to a stationary distribution and that the expected position is eventually the middle point between the barriers. 相似文献

Objective. We make use of individual‐level survey data from the 2006 midterm election in order to determine the degree to which redistricting affected the vote choice of whites residing in Georgia Congressional Districts 8 and 12. Methods. A multivariate probit model was used to assess the probability of voting for the GOP House candidate among voters represented by the same incumbent before and after redistricting versus voters who had been newly drawn into one of these districts. Results. Despite a national tide that favored the Democratic Party in the 2006 elections, redrawn whites were more likely to vote for the Republican challengers in the districts surveyed. Conclusions. Our findings indicate that redistricting can be used to dampen the incumbency advantage. In addition, the findings of this research also speak to the continuing Republican realignment of white voters in the Deep South and to the recognition that the effects of redistricting are dependent on political context. 相似文献

In this article, we discuss an outage‐forecasting model that we have developed. This model uses very few input variables to estimate hurricane‐induced outages prior to landfall with great predictive accuracy. We also show the results for a series of simpler models that use only publicly available data and can still estimate outages with reasonable accuracy. The intended users of these models are emergency response planners within power utilities and related government agencies. We developed our models based on the method of random forest, using data from a power distribution system serving two states in the Gulf Coast region of the United States. We also show that estimates of system reliability based on wind speed alone are not sufficient for adequately capturing the reliability of system components. We demonstrate that a multivariate approach can produce more accurate power outage predictions. 相似文献

The actions of organizational leaders are important determinants of the emergence, management, and consequences of employee emotional experience. However, the nature and dimensionality of leader emotion management and the behaviors that constitute such management are largely unknown. The authors present a comprehensive, theoretically-derived model of leader emotion management which clarifies the nature of emotion management and its role in leadership. This model also delineates the knowledge and skill-based antecedents of emotion management and the consequences of such management. Specifically, we propose linkages between particular KSAOs and specific emotion management dimensions and between those dimensions and particular individual and organizational outcomes. The model is meant to serve as a framework to guide empirical efforts in investigating the nature and correlates of leader emotion management. 相似文献

This 2½‐year, 5‐wave longitudinal study tests the hypothesis that acculturation discrepancies between Hispanic immigrant parents and adolescents would lead to compromised family functioning, which would then lead to problematic adolescent outcomes. Recent‐immigrant Hispanic parent–adolescent dyads (N = 302) completed measures of acculturation and family functioning. Adolescents completed measures of positive youth development, depressive symptoms, problem behavior, and substance use. Results indicated that Time 1 discrepancies in Hispanic culture retention, and linear trajectories in some of these discrepancies, negatively predicted adolescent positive youth development, and positively predicted adolescent depressive symptoms and binge drinking, indirectly through adolescent‐reported family functioning. The vast majority of effects were mediated rather than direct, supporting the acculturation discrepancy hypothesis. Implications for further research and intervention are discussed. 相似文献

Based on a review of empirical literature on empowering leadership, given incongruent and mixed results, the current work suggests reconsidering the effectiveness of empowering leadership. We propose a framework for examining the effectiveness of empowering leadership that considers: 1) feasibility of non-linear main effects of empowering leadership on work-related outcomes, 2) possibility of reverse causation between empowering leadership and work-related outcomes, 3) potential contradictory mediating mechanisms through which empowering leadership influences work-related outcomes, 4) consideration of boundary conditions which could alter the relationships between empowering leadership and work-related outcomes, and 5) consideration of levels-of-analysis and multilevel issues in empowering leadership. Our framework considers the multifaceted nature of empowering leadership and offers a guiding tool for advancing future research in this area. 相似文献

A popular view among specialists in electric utility economics is that the regulatory process exacerbated the negative effects of the OPEC's oil price increases during the 1970s. In contrast, Peltzman's theory of regulation suggests that regulators should "buffer" a firm from cost increases. This paper examines these contending propositions by examining the stock returns for a sample of electric utilities during the OPEC oil shock of October 1973. The data are more consistent with a buffering effect than a regulatory lag. 相似文献
