The practice of safe sex by commercial sex workers is considered to be central in preventing the transmission of AIDS in developing countries. However, anecdotal evidence suggests that sex workers may face large losses in income from using condoms because of a strong preference for condom-free sex among clients. This paper attempts to estimate the compensating differential for condom use among ...

This paper presents a machine learning methodology to improve the predictions of traditional RANS turbulence models in channel flows subject strong variations their thermophysical properties. The developed formulation contains several improvements over existing Field Inversion Machine Learning (FIML) frameworks described literature. We first showcase use efficient optimization routines automati...

Many times in both educational and social science research it is impossible to collect data that is complete. When administering a survey, for example, people may answer some questions and not others. This missing data causes a problem for researchers using structural equation modeling (SEM) techniques for data analyses. Because SEM and multivariate methods require complete data, several method...

Abstract Integrated Sustainable Land Management (ISLM) is progressively viewed as a key strategy to boost food security in Ethiopia and feed its growing population. By understanding this logical ground, paper examines the effect of ISLM technologies adoption on household security. The study relies cross-sectional household-level data collected from 414 randomly selected heads across three distr...

BACKGROUND Decision support to facilitate informed consent is increasingly important for complicated medical tests. Here, we test a theoretical model of factors influencing decisional conflict in a study examining the effects of a decision support aid that was designed to assist patients at high risk for hereditary nonpolyposis colorectal cancer (CRC) deciding whether to pursue the microsatelli...

OBJECTIVE There is a dose-response positive relationship between type A behavior (TABP) and cardiovascular disease-related symptoms. Estimates of heritability for TABP from previous studies vary; this might be explained by limitations in the sizes and compositions of the samples. METHODS This study combines a large sample size, twin and parental, data from males and females, two generations o...

The secretion of biomolecules into the extracellular milieu is a common and well-conserved phenomenon in biology. In bacteria, secreted biomolecules are not only involved in intra-species communication but they also play roles in inter-kingdom exchanges and pathogenicity. To date, released products, such as small molecules, DNA, peptides, and proteins, have been well studied in bacteria. Howeve...

We examine the role of money in a general framework that allows for three competing environments: the New Keynesian model with separable utility and static money demand; the non-separable utility variant with habit formation; and the New Keynesian model modi…ed to allow for adjustment costs for holding real balances. The last two models imply a forward-looking character of real money balances, ...

We consider the linkage between stock prices and exchange rates in four Middle East emerging markets. The existing evidence on stock prices and exchange rates typically relies on introduction of a global market index. On the contrary, we find that for the countries of our sample oil prices emerge as the dominant factor in the above relationship. When we focus on the extended sample we do not de...

This essay presents estimates of the monetary policymakers' preferences of the Euro Area, using quarterly aggregate Area data for 1972-2001. The analysis is motivated by the observation that the tradeoff between the volatility of inflation and the volatility of the unemployment gap has improved, in the Euro Area, since the second half of the 80s. This research tries to evaluate the role played ...
