Models specifying the utility of another child as either a couple or an individual experience and incorporating variations in the measurement properties of responses about child utility and expectations are estimated with data from the U.S. Value of Children survey. Full information, maximum likelihood analyses indicate that child utility is an individual experience of wives and husbands rather than a shared couple experience. That is, differences in the measurement properties of wives’ and husbands’ responses do not account entirely for the less than perfect correlations between their responses. These findings demonstrate the importance of estimating errors in measurement in the analysis of wives’ and husbands’ responses about the utility of children, and they challenge the assumption that marital partners share the utility of children. 相似文献

This paper studies the familial association of neonatal mortality in Matlab, Bangladesh and its relationship to birth-spacing effects on mortality. Findings show that familial association is strongest for siblings of adjacent birth orders. Moreover, birth-spacing effects on neonatal mortality are stronger when the preceding child has survived the neonatal period than when it has died. Transitional (Markov), random-effects, and marginal models for correlated data are introduced, and are contrasted in interpretation and technique. Familial association of neonatal mortality can be approximated well by a first-order Markov model using generalized estimating equations (GEE) to allow for higher-order correlation. 相似文献

Although project portfolio management has been an active research area over the past 50 years, budget allocation models that consider competition are sparse. Faced with the competition, firms contemplating budget allocation for their project portfolio cannot limit their attention to the returns from their projects' target markets, as is the case for monopoly firms, but must also anticipate the competitive effects on these returns. Assuming firms allocate their budgets between projects offering incremental innovation targeting a mature market and projects offering radical innovation targeting an emerging market, we show that while the monopoly firm bases its budget allocation decision solely on the marginal returns of the markets, competing firms—as they take into account their counterparts' investment decisions—need to also consider the projects' average returns from their respective markets. This drives competing firms into incrementalism: faced with competition, firms invest larger portions of their budgets into projects targeting mature markets. This effect is amplified as the number of competing firms increases and firms allocate an even greater share of their budget into projects targeting a mature market. We further demonstrate the effects that changes to firms' individual budgets, as well as to market characteristics, have on firms' budget allocation decision. 相似文献

We develop a formal theory of legitimate collective choice. In our theory a policy choice is legitimate if the process through which the final choice was determined is consistent with some principle that can be used to (perhaps partially) rank the potential policy choices. The set of principles in any choice situation is taken to be exogenous, but a decision-making process is defined so as to deal with any nontrivial set of principles. Such a process is itself referred to as legitimate if it is guaranteed to select a legitimate outcome for each possible exogenous set of principles. We characterize the class of procedures that are legitimate, prove that legitimate policy decisions consistent with principles always exist and characterize the set of policy decisions that are legitimate for a any given set of principles. As we do not require the principles to be weak orders of the alternatives, our theory provides a notion of legitimacy that can be satisfied even when the guiding principles are potentially cyclic or incomplete. Accordingly, our theory illustrates one nontautological means by which majoritarian principles can be reconciled with legitimacy. 相似文献

While some scholars have recognized the importance of child care to families in the United States (Kamerman, 2001; Waldfogel, 1998), child care has not been viewed as a core social policy concern in the United States. In this article, we provide an overview of child care needs in the U.S. followed by an analysis of three major federal programs that shape U.S. child care policy. The first, the Child Care Development Fund (CCDF), provides financial child care supplements to low-income parents to enable them to engage in paid labor. The second policy, The Family Medical Leave Act (FMLA), is technically a universally applicable policy enabling people to care for a family member in need, including all parents who choose to spend a few weeks of unpaid leave with a newborn child. The third is the U.S. tax policy, including child care exemptions, deductions and credits. We suggest that, though all of these policies exist to help families care for children, they fail the children and families that they are purportedly designed to help. We then discuss the crucial role that professionals who work with families and children can play in shaping U.S. child care policies. 相似文献

A major challenge in child welfare is whether a program (or service) developed and successfully implemented in one jurisdiction, especially another country, will attain the same outcomes for children and families in another jurisdiction? This paper presents the “DCE Classification System” (Defining, Classifying, and Evaluating), a classification system that facilitates cross-jurisdiction comparisons of child and family services. The paper reviews the cross-national research literature in child and family services as well as literature on classification schemes and typologies. As an example of the issues that arise when importing a promising program, we briefly highlight the exporting and importing of family group conferencing. After tracing the history and development of the DCE Classification System, the paper describes the proposed classification scheme, and provides a brief example of how researchers and practitioners can use the classification system for cross-national comparisons of client outcomes and program costs. Finally, we discuss the strengths and weaknesses of this approach, as well as possible benefits for child and family practices. 相似文献

Increased recognition of the consequences associated with child maltreatment has led to greater emphasis on its prevention. Promising maltreatment prevention strategies have been identified, but research continues to suffer from methodological limitations and a narrow focus on select prevention models. This investigation uses data from the Chicago Longitudinal Study to examine mediating mechanisms that link the Chicago Child-Parent Center preschool program to a reduction in overall child maltreatment and, more specifically, child neglect. We use structural equation modeling to test child, family, and school measures hypothesized to mediate the effects of CPC participation on maltreatment and neglect. Results indicate that a substantial proportion of the program's impacts can be accounted for by family support processes, including increased parent involvement in school and maternal educational attainment as well as decreased family problems. The CPC program's association with reduced school mobility and increased attendance in higher-quality schools also significantly mediated its effects on maltreatment and neglect. Further, a decrease in troublemaking behavior contributed modestly to mediating the program's association with maltreatment but not neglect. We discuss the implications of these results for the field of maltreatment prevention. 相似文献

Sustained mass media campaigns have been recommended to stem the tobacco epidemic in the United States. Propensity score matching (PSM) was used to estimate the effect of awareness of a national smoking cessation media campaign (EX) on quit attempts and cessation-related cognition. Participants were 4,067 smokers and recent quitters aged 18-49 in targeted U.S. media markets. Controlling for potential confounders through PSM and regression analysis, confirmed awareness of EX was not significantly associated with either outcome at 6-month follow-up. Matched analyses excluding 217 quitters resulted in a significant effect of EX on both outcomes. 相似文献

Child poverty in the United States persists despite a range of social services designed to reduce poverty rates and improve the economic self-sufficiency of families. The economic downturns resulting in job losses and the housing crisis have converged to create a new group of families who were managing to remain out of poverty prior to the recession but are now slipping into poverty, putting additional strain on services. In light of these pressing issues, this article synthesizes the literature examining child poverty to take a long-range view of the relationship between economic strain, system involvement, and impacts on children and the systems attempting to serve these children. The effectiveness of various policy and program efforts aimed at reducing child poverty rates and/or ameliorating the negative effects of living in poverty is reviewed. The article concludes by suggesting a major shift in focus from reducing child poverty as a singular goal to a comprehensive approach to promoting child and family well-being. 相似文献
