Using longitudinal data from the China Family Panel Studies, this study provides insights on comparative wellbeing outcomes for older people who are institutionally segregated into clusters that produce uneven social capital. We present the first study that examines how institutionalized social capital inequality, measured by the social capital gap generated by hukou (household registration) status in China, affects the wellbeing of older people. Our results show that high levels of social capital inequality are associated with lower subjective wellbeing, measured by life satisfaction. This general conclusion is robust to a number of sensitivity checks including alternative ways of measuring subjective wellbeing and inequality. We also find that the negative relationship between social capital inequality and subjective wellbeing is strongest for people with a non-urban hukou living in urban areas. Our findings highlight the need for policies aimed at narrowing the social capital gap and the dismantling of institutional structures that hinder upward social capital mobility.
This paper seeks to discover whether the known inaccuracy of informant recall about their communication behavior can be accounted for by experimentally varying the time period over which recall takes place. The experiment took advantage of a new communications medium (computer conferencing) which enabled us to monitor automatically all the interactions involving a subset of the computer network. The experiment itself was administered entirely by the computer, which interviewed informants and recorded their responses. Variations in time period failed to account for much of the inaccuracy, which continues, as in previous experiments at an unacceptably high level. One positive finding did emerge: although the informants did not know with whom they communicated, the informants en masse seemed to know certain broad facts about the communication pattern. All other findings were negative. For example, it is impossible to predict the people an informant claimed to communicate with but did not; and it is impossible to predict who the five people are that an informant forgot to mention that she or he had communication with. Thus, despite their presumed good intentions, our findings here confirm what we have learned from six previous experiments: What people say about their communications bears no resemblance to their behavior. This suggests that other forms of data gathering, based on questions which require that informants recall their behavior, may well be suspect. 相似文献
Connections between evangelicalism and political behavior are explored using National Election Study (NES) data from 1980 to 2004. Our findings suggest that although white evangelical support for Republican presidential candidates has increased, the independent effect of evangelicalism on voting has weakened. We argue that this reflects an increasing convergence between evangelicalism and Republican Party identification. Beginning in the 1990s, as more and more evangelicals identified as Republicans, the independent effect of their religious commitment on voting weakened. We also find strengthening correlations between evangelicalism and policy preferences, especially on non-social issues, and enhanced Republican mobilization of evangelical voters in recent campaigns. We conclude with the suggestion that changes in evangelical political behavior over a 24-year period support the notion of an electoral realignment in American politics. 相似文献
Point estimates that are weighted averages of other estimates are considered. They are adaptive because the weights are also functions of the sample observations.In particular, the weights are functions of new measures of peakedness and skewness. Five adaptive estimators are compared (in a Monte Carlo study using the swindle) to some of the usual estimators, including those robust ones of Huber and Tukey. In addition, the swindle constant is considered in some detail. All of the adaptive estimators do extremely well with an adaptive biweight statistic being the best one in this study. Suggestions are made about future directions in this area. 相似文献
Experience with small group production systems has shown that mere change of layout and introduction of groups on the shop floor do not achieve the main objectives and possible advantages of groups, unless they are accompanied by certain changes in supporting services. Probably the most important changes are those required in production control. It is absolutely vital that the requirements and characteristics of the manufacturing system are taken into account when designing the production control system and vice versa. This paper outlines the problems and important factors affecting production control in a Group Technology (GT) environment, together with case studies which describe the operation of production planning and control systems used in two different organisations. 相似文献
This study provides detailed statistics by state, industry, occupation, and worker characteristics on private sector wage
and salary workers covered by union collective bargaining agreements but who are not union members. A distinction is made
between those workers who value the benefits of coverage more than the cost of membership, the true free riders, and those
who do not, the induced riders. A probit union membership equation is estimated on a sample which excludes the covered nonmembers.
Predicted probabilities are then calculated from the estimated model, yielding a quantifiable measure of the true free-rider
problem.
