The use of web-based surveys to gather information from teachers has become increasingly common primarily based on the premise that they can reduce costs. Yet, relatively, little is known about the quality or cost effectiveness of web-based versus mail surveys for teachers. To study the efficacy of web-based teacher surveys, the author randomly assigned a nationally representative sample of 877 elementary school teachers to a paper or web survey mode. The cost savings from the web administration were not enough to offset the loss of sample due to missing/inaccurate email addresses and the lower response rates that resulted from the web survey.  相似文献

This study examined whether cognitive control mediated the association between socioeconomic status (SES; composite of income‐to‐needs ratio and parent education) and changes in risk‐taking behaviors. The sample included 167 dyads of adolescents (53% male; Mage = 14.07 years at Time 1) and their parents, assessed annually across 4 years. Parents reported socioeconomic variables at Time 1. Adolescents reported risk‐taking behaviors at Times 1 and 4, and completed a functional magnetic resonance imaging cognitive control task at Times 2 and 3. Lower SES was associated with lower behavioral (but not neural) cognitive control, which was associated with increases in risk‐taking behaviors. The findings suggest that elevated socioeconomic risk may compromise cognitive control which can cascade into maladaptive behaviors in adolescence.  相似文献

The notion of ‘think manager–think male’ has been demonstrated in many studies. The current study examines whether leaders are perceived as more effective when they have ‘feminine’, ‘masculine’ or ‘androgynous’ characteristics, and how this relates to the leader's and followers' sex. Using carefully matched samples of 930 employees of 76 bank managers, we studied the relationship between managers' gender-role identity (perceived ‘femininity’, ‘masculinity’ and ‘androgyny’) and how this relates to leadership effectiveness in terms of transformational leadership and personal identification with the leader. Our findings show that among both male and female leaders, ‘androgyny’ was more strongly related to transformational leadership and followers' identification than ‘non-androgyny’, and that leaders' ‘femininity’ was more strongly related to leadership effectiveness than ‘masculinity’. Furthermore, the results show that women paid a higher penalty for not being perceived as ‘androgynous’ (mixing ‘femininity’ and ‘masculinity’), in comparison to men with regard to personal identification. When examining same- versus cross-sex relationships, we found that ‘non-androgynous’ male managers were rated higher by their male employees than by their female employees. Our findings suggest that women and men who are interested in being perceived as effective leaders may be well advised to blend ‘feminine’ and ‘masculine’ behaviors, and even more so when they are in situations of non-congruency (i.e., women in leadership roles and leading in cross-sex relationships). We discuss the implications of these findings for both theory and practice.  相似文献

Objective. Using Poisson‐based negative binomial regression, we estimate the effect of neighborhood factors on homicides in two cities (San Antonio, Texas and San Diego, California) that have large Mexican‐origin populations. Methods. Three independent data sources (official homicide police reports, medical examiner records, and the U.S. Census) are used to construct the dependent homicide, and independent neighborhood, variables. Census tracts represent the unit of analysis, which serve as a proxy for neighborhoods. Given the spatial nature of the data, spatial estimation procedures were also modeled. Results. Spatial proximity to violence, neighborhood disadvantage, and affluence (in San Antonio) consistently buffered homicide across neighborhoods, even in heavily populated Latino neighborhoods. Conclusions. Spatial embeddedness and neighborhood characteristics are important for improving our understanding about ethnic neighborhood variations in levels of violence. Comparative approaches across places, namely, Latino‐dominated cities, can yield considerable insight into how the local context intersects race/ethnicity and violent crime.  相似文献

ABSTRACT

Heteronormativity is a culturally embedded system defining acceptable identities and behaviors in romantic relationships. Recent literature has suggested that heteronormativity is strongly associated with political attitudes, personality characteristics such as tolerance of ambiguity, and key demographic variables such as gender and sexual orientation. However, interactions between gender and other factors have not been thoroughly explored as predictors of heteronormative attitude and beliefs. The current study (N = 306) expands the understanding of predictors of heteronormativity, particularly as they interact with gender. In the current study, higher education was associated with lower heteronormativity among women, but not among men, and expressiveness was associated with lower heteronormativity among men, but not among women. Finally, a 3-way interaction showed that the relationship between education and heteronormativity for men (but not women) depended on trait expressiveness. Future studies are recommended, including observation of changes in heteronormativity over time and exploration of mechanisms that reinforce or reduce heteronormativity.  相似文献

In this article, the authors explore the impact of women on nonprofit boards. From a sociological perspective, they look at the actual proportion of women on boards and, from a more psychological perspective, at the sex of the chief executive officers in order to examine the impact of these variables on board effectiveness, structure, and process. The study results, based on data from a cross section of Canadian nonprofits, indicate that as the percentage of women on a board increases, the dynamics of the board are significantly affected.  相似文献

Rural often is viewed as a setting for study rather than an object of study. Often a priori definitions of rural are used; these definitions may bear little resemblance to residents' understanding of the concept. A cognitive mapping experiment to explore the meaning of rural is undertaken in this paper. Results indicate that urban residents could readily identify rural areas on a blank map of Pennsylvania. Their responses to the question varied, however, with some respondents indicating urban areas or writing images on the map. A discussion of these thought processes and implications from these varying responses are presented. Then, the cognitive maps are compared to three commonly accepted definitions of rural. Population density was found to best approximate the areas that urban residents perceived as rural. The paper concludes by discussing policy implications of the findings.  相似文献

We develop a pre-test type estimator of a deterministic parameter vector ββ in a linear Gaussian regression model. In contrast to conventional pre-test strategies, that do not dominate the least-squares (LS) method in terms of mean-squared error (MSE), our technique is shown to dominate LS when the effective dimension is greater than or equal to 4. Our estimator is based on a simple and intuitive approach in which we first determine the linear minimum MSE (MMSE) estimate that minimizes the MSE. Since the unknown vector ββ is deterministic, the MSE, and consequently the MMSE solution, will depend in general on ββ and therefore cannot be implemented. Instead, we propose applying the linear MMSE strategy with the LS substituted for the true value of ββ to obtain a new estimate. We then use the current estimate in conjunction with the linear MMSE solution to generate another estimate and continue iterating until convergence. As we show, the limit is a pre-test type method which is zero when the norm of the data is small, and is otherwise a non-linear shrinkage of LS.  相似文献

Using structural equation modeling, the present study investigated relationships between neuroticism, coping strategies, and negative career thoughts within the context of attaining a positive career decision state. Results from the initial model, based on a sample of college students (119 women, 113 men; M = 20.3 years) enrolled in a career development course, revealed that coping strategies were not a significant contribution to the model. The final model, without coping strategies, showed that neuroticism had a significant indirect effect on career decision state through negative thinking and that the relationship between neuroticism and career decision state was also significant. Findings also indicate that in the presence of negative career thoughts, neuroticism becomes associated with a more positive career decision state. Practical implications include suggestions that counselors intervene on clients' negative career thoughts to potentially render their neurotic tendencies more productive in reaching a desired career decision state.  相似文献
