The astronomical diaries from Babylonia (ADB) are excellent sources of information of natural phenomena, including astronomical ones, in pre-Christ era because it contains the record of highly continuous and systematic observations. In this article, we present results of a survey of aurora-like phenomena in ADB, spanning from BCE 652 to BCE 61. We have found nine records of aurora-like phenomen...
BACKGROUND Canadian normative data for the Medical Outcomes Study 36-item short form (SF-36) have recently been published. However, there is evidence from other countries to suggest that regional variation in health-related quality of life (HRQOL) may exist. We therefore examined the SF-36 data from nine Canadian centres for evidence of systematic differences. METHODS Bayesian hierarchical mo...
Animal research is debated highly controversial, as evident by the "Stop Vivi-section" initiative in 2015. Despite widespread protest to the initiative by researchers, no data is available on the European medical research community's opinion towards animal research. In this single-center study, we investigated this question in a survey of students and staff members at the Medical University of ...

Four hundred seventy-six student employees completed the survey in March 2010. The majority of respondents were female (66%) and the average age of all respondents was 20.7 yr. A pre-validated survey instrument was taken from the Youth Employment ...
In this paper we explore the strengths and gaps among NGO surveys based on an analysis of the records held in the CE-DAT database at CRED. We conclude by recommending the priority areas for strengthening NGO capacity to undertake surveys and ways to improve data quality in general.
"In this article we describe a logistic regression modeling approach for nonresponse in the [U.S.] Post-Enumeration Survey (PES) that has desirable theoretical properties and that has performed well in practice.... In the 1990 PES, interviews were not obtained from approximately 1.2% of households in the sample, and approximately 2.1% of the individuals in interviewed households were considered...
Ð We use Demographic and Health Surveys (DHS) to compare ``poverty'' at two or more points in time within and between African countries. Our welfare measure is an index resulting from a factor analysis of various household characteristics, durables, and household headsÕ education. An advantage of this measure is that for intertemporal and intraregional comparisons, we need not rely on suspect p...
We document the impact of the AIDS crisis on non-AIDS-related health services in 14 sub-Saharan African countries. Using multiple waves of Demographic and Health Surveys (DHS) for each country, we examine antenatal care, birth deliveries, and rates of immunization for children born between 1988 and 2005. We find deterioration in nearly all these dimensions of health care over this period. The m...
Commonly available survey data for developing countries often do not include income or expenditure data. This data limitation puts severe constraints on standard poverty and inequality analyses. We provide a simple approach to simulate household income based on publicly available Demographic and Health Surveys (DHS) and macroeconomic data. We illustrate our approach with DHS data for Bolivia, B...
