Housing insecurity and sleep among welfare recipients in California.

Study Objectives: To estimate the effect of housing insecurity on sleep duration and sleep quality.

Methods: Using longitudinal data from a sample of 1,046 welfare recipients in the state of California followed from 2015-2016 through 2017-2018, we regressed self-reported measures of sleep duration and sleep quality recorded in 2017-2018 on experiences of housing insecurity in the prior year. We applied propensity score weights to attenuate potential bias from an array of observed covariates, including sleep duration and sleep quality measured prior to experiences with housing insecurity.

Seismic Model Parameter Optimization for Building Structures.

Structural dynamic modeling is a key element in the analysis of building behavior for different environmental factors. Having this in mind, the authors propose a simple nonlinear model for studying the behavior of buildings in the case of earthquakes. Structural analysis is a key component of seismic design and evaluation.

Investing Early: Taking Stock of Outcomes and Economic Returns from Early Childhood Programs.

The past two decades have been characterized by a growing body of research from diverse disciplines-child development, psychology, neuroscience, and economics, among others-demonstrating the importance of establishing a strong foundation in the early years of life. The research evidence has served to document the range of early childhood services that can successfully put children and families on the path toward lifelong health and well-being, especially those at greatest risk of poor outcomes. As early childhood interventions have proliferated, researchers have evaluated whether the programs improve children's outcomes and, when they do, whether the improved outcomes generate benefits that can outweigh the program costs.

Standards of Evidence for Conducting and Reporting Economic Evaluations in Prevention Science.

Over a decade ago, the Society for Prevention Research endorsed the first standards of evidence for research in preventive interventions. The growing recognition of the need to use limited resources to make sound investments in prevention led the Board of Directors to charge a new task force to set standards for research in analysis of the economic impact of preventive interventions. This article reports the findings of this group's deliberations, proposes standards for economic analyses, and identifies opportunities for future prevention science.

Intended And Unintended Effects Of The War On Poverty: What Research Tells Us And Implications For Policy.

During the mid-1960s, the United States adopted a series of cash and in-kind transfer programs, as well as human capital investment strategies, as part of the War on Poverty. A number of other programs were first proposed as part of this "war" but were not implemented until the mid-1970s. These programs had noble goals: to increase incomes at the bottom of the income distribution, reduce poverty, and improve nutrition, heath, and human capital.
