This article quantifies the extent to which socioeconomic and demographic characteristics can account for black-white disparities
in life expectancy in the United States. Although many studies have investigated the linkages between race, socioeconomic
status, and mortality, this article is the first to measure how much of the life expectancy gap remains after differences
in mortality are purged of the compositional differences in socioeconomic characteristics between blacks and whites. The decomposition
is facilitated by a reweighting technique that creates counterfactual estimation samples in which the distribution of income,
education, employment and occupation, marital status, and other theoretically relevant variables among blacks is made to match
the distribution of these variables among whites. For males, 80% of the black-white gap in life expectancy at age 1 can be
accounted for by differences in socioeconomic and demographic characteristics. For females, 70% percent of the gap is accounted
for. Labor force participation, occupation, and (among women only) marital status have almost no additional power to explain
the black-white disparity in life expectancy after precise measures for income and education are controlled for. 相似文献

Using data from the 2003?C2007 American Time Use Surveys (ATUS), we compare mothers?? (N = 6,640) time spent in four parenting activities across maternal education and child age subgroups. We test the hypothesis that highly educated mothers not only spend more time in active child care than less-educated mothers but also alter the composition of that time to suit children??s developmental needs more than less-educated mothers. Results support this hypothesis: not only do highly educated mothers invest more time in basic care and play when youngest children are infants or toddlers than when children are older, but differences across education groups in basic care and play time are largest among mothers with infants or toddlers; by contrast, highly educated mothers invest more time in management activities when children are 6 to 13?years old than when children are younger, and differences across education groups in management are largest among mothers with school-aged children. These patterns indicate that the education gradient in mothers?? time with children is characterized by a ??developmental gradient.?? 相似文献

This paper presents results from a survey on attitudes toward climate change in Alberta, Canada, home to just 10% of Canada??s population, but the source of 35% of the country??s greenhouse-gas emissions (Environment Canada 2011). Results show high levels of awareness, but much lower levels of perceived climate change impacts for one??s self or region. Women expressed significantly greater awareness and sense of perceived impacts about climate change than men; however, gender differences appear predominantly associated with socioeconomic factors. Indeed, in all, political ideology had the strongest predictive value, with individuals voting for the conservative party significantly less likely to anticipate significant societal climate change impacts. This finding, in turn, is strongly associated with beliefs regarding whether climate change is human induced. Particularly notable is the finding that the gender gap in climate change beliefs and perceived impacts is not attributed to gendered social roles, as indicated by occupational and familial status. Instead, gender distinctions appear to be related to the lower tendency for women to ascribe to a conservative political ideology relative to men. 相似文献

This study focuses on the role of social policies in mitigating work-family incompatibilities in 27 countries. We ask whether work-family conflict is reduced in countries that provide family-friendly policies and flexible employment arrangements, and whether women and men are similarly affected by such policies. The study, based on the ISSP 2002, demonstrates considerable variation among countries in the perceived work-family conflict. In all but two countries, women report higher levels of conflict than men. At the individual level, working hours, the presence of children and work characteristics affect the perception of conflict. At the macro level, childcare availability and to a certain extent maternity leave reduce women's and men's sense of conflict. Additionally, the availability of childcare facilities alleviates the adverse effect of children on work-family balance for mothers while flexible job arrangements intensify this effect. 相似文献

Adapted from the weed risk assessment (WRA) of Pheloung, Williams, and Halloy, the fish invasiveness scoring kit (FISK) was proposed as a screening tool for freshwater fishes. This article describes improvements to FISK, in particular the incorporation of confidence (certainty/uncertainty) ranking of the assessors' responses, and reports on the calibration of the score system, specifically: determination of most appropriate score thresholds for classifying nonnative species into low-, medium-, and high-risk categories, assessment of the patterns of assessors' confidences in their responses in the FISK assessments. Using receiver operating characteristic (ROC) curves, FISK was demonstrated to distinguish accurately (and with statistical confidence) between potentially invasive and noninvasive species of nonnative fishes, with the statistically appropriate threshold score for high-risk species scores being ≥19. Within the group of species classed as high risk using this new threshold, a "higher risk" category could be visually identified, at present consisting of two species (topmouth gudgeon Pseudorasbora parva and gibel carp Carassius gibelio ). FISK represents a useful and viable tool to aid decision- and policymakers in assessing and classifying freshwater fishes according to their potential invasiveness. 相似文献

This study is a replication of “Are Muslim Immigrants Different in terms of Cultural Integration?” by Alberto Bisin, Eleonora Patacchini, Thierry Verdier and Yves Zenou, published in the Journal of the European Economic Association, 6, 445–456, 2008. Bisin et al. (2008) report that they have 5,963 observations in their study. Using their empirical setup, we can only identify 1,901 relevant observations in the original data. After removing missing values we are left with 818 observations. We cannot replicate any of their results and our estimations yield no support for their claims. 相似文献

As service failures are inevitable, firms must be prepared to recover and learn from service failures. Yet, the majority of customers are still dissatisfied with the way firms resolve their complaints. Can learning to reduce service failures reduce customer dissatisfaction, and to what extent are such reductions sustainable? Previous research showed that organizational learning curves for customer dissatisfaction (i) follow a U‐shaped function of operating experience and (ii) are heterogeneous across firms. In this paper, I tease out where the U‐shaped learning‐curve effect and learning‐curve heterogeneity originate: service failure or customers' propensity to complain with a third party given the occurrence of a service failure. Using quarterly data for nine major US airlines over 11 years, I find that the U‐shaped learning‐curve effect and the learning‐curve heterogeneity originate in the propensity to complain. In the long term, reductions in service failure did not translate in sustainable reductions in customer dissatisfaction. Customers' propensity to complain eventually went up. Managing the propensity to complain provides more opportunity for a firm to distinguish itself from competitors. 相似文献

Assimilation and multiculturalism are often contrasted as opposite interethnic ideologies about cultural integration. Here, we address models of assimilation and multiculturalism and how group identity influences attitudes toward immigrants. One overlooked issue concerns the dynamic processes involved in integration. It is proposed that cultural inertia, defined as the desire to avoid cultural change, or conversely, to continue change once it is already occurring, can account for a number of seemingly discrepant findings. In particular, cultural inertia predicts that majority groups should prefer assimilation type models, whereas minority groups should prefer multicultural models. Resistance to change is the mediating process. Cultural inertia is used as a model to understand discrepant attitudes toward assimilation and multiculturalism across different groups. 相似文献
