The purpose of this paper is to provide evidence on the effect of child health on marital stability and family structure in an economic framework. We use the 1988 National Health Interview Survey's Child Health Supplement, with a sample of about 9,000 families, to test whether having an unhealthy child decreases the mother's chance of being married and whether it increases her chance of living in an extended family. Using two different measures of child health, we find that having an unhealthy child decreases the mother's likelihood of being married. Our results imply that children in poor health are more likely to face obstacles beyond their illness because they also are more likely to suffer the consequences of poverty and the poor schooling outcomes that result from being raised in a female-headed household. The only mitigating factor is that unhealthy white children are more likely than their healthy counterparts to be living in an extended family. 相似文献

The employment circumstances of immigrants and their children constitute a key dimension along which immigrant adaptation to the U.S. can be evaluated. We describe and analyze employment adequacy—defined as underemployment—among first, second and third (or higher) immigrant generations. Analyzing CPS data for the decade spanning 1995–2004, we find support for the notion of successful economic assimilation. The prevalence of underemployment is decidedly higher among the first-generation compared to the second or third, while the latter two groups differ little in this regard. These gross comparisons, however, mask important variation within immigrant generations, including a particular disadvantage among foreign-born non-citizens. 相似文献

Local food systems (LFSs) are complex and diverse social structures. The processes that influence the formation and evolution of LFSs are obscure, relatively uncoordinated, and somewhat mysterious. This study develops a stronger understanding of such processes through a qualitative exploration of the influence of routine practice work at the organization level on the entrepreneurial development of two distinct LFSs in the Southwest region of the United States: southeastern Arizona and Albuquerque?Santa Fe. We gathered data between August 2014 and September 2017 through semistructured interviews with and direct observations of 53 local food practitioners operating in one of the two LFSs. Theoretical principles of institutional entrepreneurship, embedded agency, and practice work guided the study. The findings reveal three forms of ingenuity (technological, organizational, policy) that regularly emerge through the day‐to‐day organization‐level work of local food practitioners. We argue that the system‐level influence of these forms, whether intentional or not, are indicators of the embedded agency of the practitioners and their capacities to serve as institutional entrepreneurs. We discuss implications for both practice and future research. 相似文献

In linear models having near collinear columns of X, ridge and surrogate estimators often are used to mitigate collinearity. A new class of estimators is based on mixtures, either of X and a design minimal in an ordered class or of the Fisher information and a scalar matrix. Comparisons are drawn among choices for the mixing parameter, and the estimators are found to be admissible relative to ordinary least squares. Case studies demonstrate that selected mixture designs are perturbed from the original design to a lesser extent than are those of the surrogate method, while retaining reasonable efficiency characteristics. 相似文献

AbstractMany explanations offered for the gap in marriage rates between Black and White people are economic and cultural. Less often considered are how racial social psychological factors influence marriage rates. In this study, we use critical race theory and the life course perspective to investigate how perceived racial discrimination impacts the likelihood of marriage for Black and White people. Data for the study are taken from the Portraits of American Life Study (N?=?678). The results of logistic regression analyses show that among people who report perceived racial discrimination, White people generally have a higher probability of being married compared to Black people. Analyses by age demonstrate that among younger adults, Black people who perceive racial discrimination are equally likely to be married as White people and have a higher probability of being married than Black people who do not report perceptions of racial discrimination. A negative influence on the odds of marriage related to perceived racial discrimination for Black people becomes clearer as respondents age. The findings highlight the importance of considering perceptions of racial discrimination to better understand the marriage gap between Black and White people across the life course. 相似文献
