BACKGROUND The National Health Interview Survey (NHIS) was used to ascertain whether increases in inadequate sleep differentially affected black and white Americans. We tested the hypothesis that prevalence estimates of inadequate sleep were consistently greater among blacks, and that temporal changes have affected these two strata differentially. METHODS NHIS is an ongoing cross-sectional st...

METHODS The estimates in this report are based on data from NHDS and Medicare claims submitted by hospital providers for inpatient stays among Part A fee-for-service Medicare beneficiaries aged 65...

BACKGROUND Access to direct-to-consumer genetic testing services has increased in recent years. However, disparities in knowledge and awareness of these services are not well documented. We examined awareness of genetic testing services by rural/urban and racial/ethnic status. METHODS Analyses were conducted using pooled cross-sectional data from 4 waves (2011-2014) of the Health Information ...

The Impact of Amnesty on Labor Market Outcomes: A Panel Study Using the Legalized Population Survey This paper tests whether amnesty, a provision of the 1986 Immigration Reform and Control Act (IRCA), affected the labor market outcomes of the legalized population. Using the Legalized Population Survey (LPS) and the National Longitudinal Survey of Youth (NLSY79) from 1987-1992, a quasi-experimen...

CSPro (Census and Survey Processing System) is a software package used recently in many large scale surveys for data collection. This software often used as desktop software has been used for the first time as a web service for resolving some problems encountered in the first wave of the Morocco Household Panel Survey (MHSP). The article will outline the Survey Management Web Platform that has ...

In this paper, we propose new methods for investigating the extent of heterogeneity in effective contact rates relevant to the transmission of infections. These methods exploit the correlations between ages at infection for different infections within individuals. The methods are developed for serological surveys, which provide accessible individual data on several infections, and are applied t...

Prediction markets and other reward mechanisms based on proper scoring rules can elicit accurate predictions about future events with public outcomes. However, many questions of public interest do not always have a clear answer. For example, facts such as the effects of raising or lowering interest rates can never be publicly verified, since only one option will be implemented. In this paper we...

Previous research finds that voting is a socially stressful activity associated with increases in cortisol levels. Here we extend this research by investigating whether different voting modalities have differential effects on the stress response to voting. Results from a field experiment conducted during the 2012 presidential elections strongly suggest that traditional "at the polls" voting is ...

Critics of public opinion polls often claim that methodological shortcuts taken to collect timely data produce biased results. This study compares two random digit dial national telephone surveys that used identical questionnaires but very different levels of effort: a "Standard" survey conducted over a 5-day period that used a sample of adults who were home when the interviewer called, and a "...

Wild product harvesting by forest-dwelling peoples, including hunting, fishing, forest product collection and timber harvesting, is believed to be a major threat to the biodiversity of tropical forests worldwide. Despite this threat, few studies have attempted to quantify these activities across time or across large spatial scales. We use a unique longitudinal household survey (n = 480) to desc...
