This study assesses the influence of household structure and resource dilution characteristics on childrens immunization coverage in Jamaica and Trinidad and Tobago. The study has three objectives: (1) to compare the impact of different types of household structures (e.g., single parent, two-parent, cohabiting and extended) on child immunization; (2) to examine the effects of household income and resource dilution on child immunization; and (3) to determine whether household structure and resource dilution interact to affect child immunization in these contexts.We use data from the Jamaica 1996 and Trinidad and Tobago 1997 Living Standards Measurement Study Survey and a series of logistic regression models to test hypotheses derived from the current child well-being literature. The results show that household income and household structures selectively predict childrens immunization coverage in both contexts, with significant interaction effects enhancing the interpretation for Jamaica. The key policy implications that emerge from this study are that household structure and income are crucial for understanding child immunization in the Caribbean. 相似文献

This study examined adolescent paternity through structured interviews with their social workers. It adds to the literature by exploring if there were young men involved with the child protection services (CPS) system who are fathers, identifying their unique needs, and beginning discussions on working with these young men. CPS social workers from six area offices and one juvenile detention facility completed surveys for each father on their caseload. A 3.5% rate of adolescent paternity was observed across these offices. Information about the nature of the young men's involvement with CPS, their involvement with their children, and their unique needs as fathers are provided. This paper also identifies some practice and policy implications for adolescent fathers and CPS charged with their care. 相似文献

Workers' ability to delay retirement depends partly on the demands of their jobs. Matching occupational characteristics from the Occupational Information Network to Current Population Survey respondents, this study finds that 7% of American workers held highly physically demanding jobs in 2006 and 35% held highly cognitively demanding jobs. The share of the workforce in physically demanding jobs fell by about one-sixth between 1971 and 2006, while the share in cognitively demanding jobs increased by more than one-third. The decline in physically demanding occupations will likely improve employment prospects for older adults, but the growth in cognitive demands may limit options for some older workers. 相似文献

Maximal flows reach at least a 1/2 approximation of the maximum flow in client-server networks. By adding 1 additional time round to any distributed maximal flow algorithm we show how this 1/2-approximation can be improved on bounded-degree networks. We call these modified maximal flows ??locally fair?? since there is a measure of fairness prescribed to each client and server in the network. Let N=(U,V,E,b) represent a client-server network with clients U, servers V, network links E, and node capacities b, where we assume that each capacity is at least one unit. Let d(u) denote the b-weighted degree of any node u??U??V, ??=max?{d(u)|u??U} and ??=min?{d(v)|v??V}. We show that a locally-fair maximal flow f achieves an approximation to the maximum flow of $\min\{1,\frac{\varDelta^{2}-\delta}{2\varDelta^{2}-\delta\varDelta-\varDelta}$ }, and this result is sharp for any given integers ?? and ??. This results are of practical importance since local-fairness loosely models the steady-state behavior of TCP/IP and these types of degree-bounds often occur naturally (or are easy to enforce) in real client-server systems. 相似文献

AbstractThis study examined how a Native American stepchild’s expectations for their stepparents’ behavior associated with the stepfamily quality. The responses of Native Americans and multiracial Native Americans were compared to the general population in order to identify cultural differences that affect stepfamily quality. Data came from the Stepfamily Experience Project (STEP). Findings suggest that Native Americans differed from other races concerning stepfamily quality, stress from the stepfamily forming, a child’s expectation for a stepparent’s control behaviors, and a child’s relationship with their biological parent. For practical use, clinicians should consider Native American stepchildren’s expectations regarding their stepparent’s behaviors in order to better assess stepfamily quality and provide more effective services. 相似文献

Investigating Risky Choices Over Losses Using Experimental Data 总被引:1,自引:0,他引:1

We conduct a battery of experiments in which agents make choices from several pairs of all-loss-lotteries. Using these choices, we estimate a representation of individual preferences over lotteries. We find statistically and economically significant departures from expected utility maximization for many subjects. We also estimate a preference representation based on summary statistics for behavior in the population of subjects, and again find departures from expected utility maximization. Our results suggest that public policies based on an expected utility approach could significantly underestimate preferences and willingness to pay for risk reduction.JEL Classification: C91, D81 相似文献
