This study uses an intersectional approach to predict attitudes toward immigrants by examining the intersections of race, class, gender, and social space. With data from the 2004 General Social Survey and the 2000 Census, generalized hierarchal linear modeling generates significant two‐way and three‐way interactions in predicting attitudes toward immigrants taking jobs, improving the economy, committing crime, and migrating to the United States. Important differences in attitudes between groups and within groups only emerge when particular intersections are considered in the analysis. One implication is that pro‐immigrant organizations may gain greater support by devising political strategies from an intersectional perspective.  相似文献

We investigated the combined effects of charismatic leadership and organizational culture on perceived and objective company performance using a longitudinal design. Employees (N = 1214) in 46 branches of a large Dutch bank rated branch management on charismatic leadership, organizational culture in terms of work practices, as well as perceived organizational performance. Objective performance data were collected twice, two years apart. The split sample technique attenuated common source bias. Results of structural equation modeling, in which Time 1 financial performance measures were controlled, revealed that charisma increased financial performance; however culture did not do so. Culture and charisma were significantly related to perceived performance, and culture and charisma were interrelated. A longer time interval may be necessary before the effects of culture on financial performance become apparent. The findings are discussed against the backdrop of the value of intangible resources.  相似文献

The concept of a moment distribution is here applied to the class of factorial series distributions introduced by the author (197U). Moment distributions turn out to have a simple interpretation in this case and often take on a simple form. A few examples are given to illustrate this fact  相似文献

Abstract

The relationship between three different performance measures and burnout was explored in 20 Dutch Intensive Care Units (ICUs). Burnout (i.e. emotional exhaustion and depersonalization) proved to be significantly related to nurses' perceptions of performance as well as to objectively assessed unit performance. Subjective performance measures relate negatively to burnout levels of nurses, whereas an objective performance measure relates positively to burnout. Furthermore, subjectively assessed personal performance (i.e. personal accomplishment) is more strongly related to burnout than subjectively assessed unit performance. A model test of the relationship between both types of subjective performance and burnout reveals that nurses' perception of unit performance is indirectly related to burnout through perception of personal performance. This model holds similarly for objectively well- and poor-performing ICUs.  相似文献

In the research literature on immigration attitudes, there are a number of theories that explain why individuals hold positive or negative opinions of certain immigrant groups and immigration policies. In this review of the literature, the theories are summarized into five categories: personal and social identity, self and group interest, cultural values and beliefs, social interaction, and multilevel theories. The majority of the theories offer explanations that favor one causal direction, focus on social psychology or the social structural environment, and assume that effects are additive rather than interactive. It is argued in this review that scholars would benefit by using multilevel theories, such as group position theory and intersectionality, in order to extend their explanatory reach past the theoretical standards and, in doing so, be able to better examine some understudied but important questions, such as why individuals often hold pro‐ and anti‐immigrant opinions simultaneously. Multilevel theories have the potential to offer a nuanced understanding of immigration attitudes.  相似文献

A bootstrap algorithm is proposed for testing Gaussianity and linearity in stationary time series, and consistency of the relevant bootstrap approximations is proven rigorously for the first time. Subba Rao and Gabr (1980) and Hinich (1982) have formulated some well-known nonparametric tests for Gaussianity and linearity based on the asymptotic distribution of the normalized bispectrum. The proposed bootstrap procedure gives an alternative way to approximate the finite-sample null distribution of such test statistics. We revisit a modified form of Hinich's test utilizing kernel smoothing, and compare its performance to the bootstrap test on several simulated data sets and two real data sets—the S&P 500 returns and the quarterly US real GNP growth rate. Interestingly, Hinich's test and the proposed bootstrapped version yield substantially different results when testing Gaussianity and linearity of the GNP data.  相似文献

An ample body of research has shown that young adults from non-intact families are more likely to leave the parental home at an early age than young adults from intact families. However, little is known about the mechanisms underlying this relationship. We drew on prospective longitudinal data from the German Socio-Economic Panel Study (SOEP) to examine why young adults from non-intact families are more likely to leave home early. Based on the feathered nest hypothesis, it was expected that young adults from non-intact families are pushed out of the parental home because of a lack in economic, social, and community resources. Moreover, it was expected that young adults from non-intact families are pulled toward independent living at a younger age because they have a partner and are employed earlier in life. We employed discrete-time event history models and used the KHB method to test relative weights of the mediators. The mediators explained 16% (women) and 22% (men) of the effect of living in a stepfamily, and 50% (women) and 37% (men) of the effect of living in a single-mother family. Economic resources were the main mediator for the effect of living in a single-mother family on early home leaving. For women, mother’s life satisfaction and housing conditions significantly explained differences in early home leaving between single-mother and intact families. For men, residential mobility significantly mediated the effect of family structure on early home leaving.  相似文献

The article presents theoretical and empirical research findings which incorporate price and replacement purchases in new product diffusion models. On the theoretical side, this paper characterizes, qualitatively, optimum pricing policies for new products. Possible entry of rivals is not considered, but repeat sales, cost learning dynamics and discounting of future profit streams are allowed. Theoretical research findings suggest that the inclusion of repeat purchases in the diffusion model significantly changes the derived optimal pricing policy even if replacements were not price dependent. On the empirical side, alternative first purchase and repeat purchase models have been estimated and compared using nonlinear procedures. The diffusion data analyzed is related to nine consumer durables. Empirical research findings suggest that, for the considered product categories, diffusion is basically an imitative process, price can affect first and replacement purchases, and unit production cost is a decreasing function of cumulative first purchases. Managerial implications of the research findings are also discussed.  相似文献

As fertility declines in low- and middle-income countries, the time women devote to childbearing and rearing may also be reduced. This shift has been described as one of the positive consequences of the demographic transition, as it opens opportunities for women to pursue educational and employment opportunities that were previously constrained by the demands of bearing and raising children. We estimate the numbers of children residing at home (with their mother) for women in 58 countries in Asia, Latin America, the Middle East and North Africa, and sub-Saharan Africa. We then examine the association between women’s employment and having children at home. Finally, we assess trends over recent decades in the relationship between employment and childbearing, and differences in this relationship by mother’s occupation. We find a negative association between women’s employment and having children at home; this association varies substantially by world region, age of child, and mother’s occupation.  相似文献
