Growth and internationalisation of the Chinese economy have reconfigured the global value chains of many commodities with important implications for industry and rural and regional development both in and outside China. This article analyses the chain for cashmere, all stages of which have gravitated to China, and the impacts on rural development, especially for herders in remote pastoral regions. Traditionally a high‐value product, cashmere has become increasingly generic and adulterated over the past decade. More formal and closer integration of Chinese actors into the global industry and re‐orienting policy from supply‐side intervention to the enforcement of standards would enhance the competitiveness of Chinese cashmere in international fibre markets. 相似文献

This paper uses data from the Fragile Families and Child Wellbeing Study to test the hypotheses that (1) similar to other
positive pre- and post-natal outcomes, Mexican immigrant mothers are more likely to breastfeed, and to breastfeed longer,
than white or Mexican-American mothers; and (2) acculturation accounts for the ethnic/nativity differential in breastfeeding
initiation and duration. The results support both hypotheses. Mexican immigrants to the U.S. are much more likely than whites
to breastfeed, and to breastfeed longer. Mexican-American mothers, after controlling for background characteristics, have
similar initiation and duration to whites. Using expanded acculturation measures developed for this paper, acculturation accounts
for some of the difference between whites and Mexican immigrants in breastfeeding initiation, and much of the difference for
breastfeeding duration. The results suggest that low levels of acculturation operate to protect Mexican immigrants from choosing
to formula-feed, which gives their babies many health advantages, and may be associated with better health outcomes across
the life course. The results also suggest that successive generations of Mexican immigrants may abandon breastfeeding, which
is deleterious for their infants. 相似文献

Among older youth transitioning from the foster care system, this longitudinal study examined the association of religious and spiritual capital to substance use in the past year at age 19. Participants consisted of African American (N = 179) and White non‐Hispanic (N = 133) older youth in foster care. Drawing from social capital theory, it was posited that religious service attendance (a proxy for religious capital) and belief in a spiritual force (a proxy for spiritual capital) would be inversely associated with substance use. Multiple logistic regression results indicated support for the first and second hypothesis for White foster youth only. Among White foster youth, more frequent religious service attendance and greater belief in a spiritual force were associated with a lower likelihood of illegal substance and polysubstance use. No association between religious or spiritual capital and substance use was found among African American foster youth. The findings underscore the importance of conducting spiritual assessments to help ensure older foster youth who have strong religious or spiritual orientations are in environments where they are accommodated and supported. 相似文献

The claim that multiple partner fertility may pose a risk of adverse outcomes for children has not been tested. We test this argument using a sample of 4,027 resident fathers and children from the Fragile Families and Child Well‐being Survey by examining the pathways through which fathers' multipartnered fertility is associated with children's externalizing behaviors and physical health status at 36 months. Path analyses indicate that multiple partner fertility exerted both a significant direct and indirect effect through paternal depression to influence children's externalizing behaviors. Fathers' multiple partner fertility also exerted a significant indirect effect through one mediator—father involvement—to influence children's physical health. This evidence suggests that the disruptions brought about by multipartnered fertility are important for understanding child well‐being. 相似文献

We estimate a mixed logit model of the demand for local news service. Results provide evidence that suggest the representative consumer values more diverse news, more coverage of multicultural issues, and more information on community news, and has a distaste for advertising. Demand estimates are used to calculate the impact on consumer welfare from a marginal decrease in the number of independent television stations that lowers the amount of diversity, multiculturalism, community news, and advertising. Consumer welfare decreases, but the losses are smaller in large markets. For example, small‐market consumers lose $45 million annually while large‐market consumers lose $13 million.

New, “big data” sources allow measurement of city characteristics and outcome variables at higher collection frequencies and more granular geographic scales than ever before. However, big data will not solve large urban social science questions on its own. Big urban data has the most value for the study of cities when it allows measurement of the previously opaque, or when it can be coupled with exogenous shocks to people or place. We describe a number of new urban data sources and illustrate how they can be used to improve the study and function of cities. We first show how Google Street View images can be used to predict income in New York City, suggesting that similar imagery data can be used to map wealth and poverty in previously unmeasured areas of the developing world. We then discuss how survey techniques can be improved to better measure willingness to pay for urban amenities. Finally, we explain how Internet data is being used to improve the quality of city services. (JEL R1, C8, C18) 相似文献

An Empirical Approach to Sufficient Similarity: Combining Exposure Data and Mixtures Toxicology Data
Scott Marshall Chris Gennings Linda K. Teuschler LeAnna G. Stork Rogelio Tornero‐Velez Kevin M. Crofton Glenn E. Rice 《Risk analysis》2013,33(9):1582-1595
When assessing risks posed by environmental chemical mixtures, whole mixture approaches are preferred to component approaches. When toxicological data on whole mixtures as they occur in the environment are not available, Environmental Protection Agency guidance states that toxicity data from a mixture considered “sufficiently similar” to the environmental mixture can serve as a surrogate. We propose a novel method to examine whether mixtures are sufficiently similar, when exposure data and mixture toxicity study data from at least one representative mixture are available. We define sufficient similarity using equivalence testing methodology comparing the distance between benchmark dose estimates for mixtures in both data‐rich and data‐poor cases. We construct a “similar mixtures risk indicator”(SMRI) (analogous to the hazard index) on sufficiently similar mixtures linking exposure data with mixtures toxicology data. The methods are illustrated using pyrethroid mixtures occurrence data collected in child care centers (CCC) and dose‐response data examining acute neurobehavioral effects of pyrethroid mixtures in rats. Our method shows that the mixtures from 90% of the CCCs were sufficiently similar to the dose‐response study mixture. Using exposure estimates for a hypothetical child, the 95th percentile of the (weighted) SMRI for these sufficiently similar mixtures was 0.20 (i.e., where SMRI <1, less concern; >1, more concern). 相似文献

As labour markets have become more complex there has been increasing interest among researchers in understanding the ways
that social and labour market processes and contexts impact on various labour market states. One important area has been in
understanding the differences between unemployment and hidden unemployment. This paper considers the ways in which these two
labour market states differ for a sample of male and female respondents to the Household Income and Labour Dynamics Australia
(HILDA) survey. It presents data related to the reasons why respondents in these two labour force states consider they are
jobless and analyses the characteristics of male and female respondents in the two labour market states to consider differences
in outcomes. The findings suggest that there are differences in the two states of labour market outcomes and that these are
further complicated when one considers processes for males and females. 相似文献
