One hundred and two brackish water shrimp farms in Shyamnagar Upazila of Satkhira District, Bangladesh, were surveyed to study their costs and returns. Key data were collected, using a questionnaire survey from January to August 2002. Profitability of operations was affected by fluctuating yields and prices due to diseases, and generated economic risk. The(More)
BACKGROUND Higher ambient fine particulate matter (PM₂.₅) levels can be associated with increased blood pressure and vascular dysfunction. OBJECTIVES To determine the differential effects on blood pressure and vascular function of daily changes in community ambient- versus personal-level PM₂.₅ measurements. METHODS Cardiovascular outcomes included(More)
BACKGROUND Recent advances in GIS technology and remote sensing have provided new opportunities to collect ecologic data on agricultural pesticide exposure. Many pesticide studies have used historical or records-based data on crops and their associated pesticide applications to estimate exposure by measuring residential proximity to agricultural fields.(More)
The PhenX Toolkit provides researchers with recommended, well-established, low-burden measures suitable for human subject research. The database of Genotypes and Phenotypes (dbGaP) is the data repository for a variety of studies funded by the National Institutes of Health, including genome-wide association studies. The dbGaP requires that investigators(More)
We develop bootstrap methods for constructing conndence regions, including intervals and simultaneous bands, in the context of estimating the intensity function of a non-stationary Poisson process. Several diierent resampling algorithms are suggested, ranging from resampling a Poisson process with intensity equal to that estimated nonparametrically from the(More)
The US Environmental Protection Agency recently conducted the Detroit Exposure and Aerosol Research Study (DEARS). The study began in 2004 and involved community, residential, and personal-based measurements of air pollutants targeting 120 participants and their residences. The primary goal of the study was to evaluate and describe the relationship between(More)
People who are food and nutrition insecure largely reside in Asia and Sub-Saharan Africa and for many, fish represents a rich source of protein, micronutrients and essential fatty acids. The contribution of fish to household food and nutrition security depends upon availability, access and cultural and personal preferences. Access is largely determined by(More)
Access to accurate information and technical expertise is a pre-requisite for informed decision making. The Network of Aquaculture Centres in Asia-Pacific (NACA), an intergovernmental organization of 17 governments in Asia-Pacific, works on the principle of cooperation and collaboration with the intention of sharing regional resources amongst the(More)
Disease is one of the gravest threats to the sustainability of the aquaculture industry. A good understanding of biosecurity and disease causation is essential for developing and implementing farm-level plans and husbandry measures to respond to disease emergencies. Using epidemiological approaches, it is possible to identify pond- and farm-level risk(More)
The focus of the PhenX (Phenotypes and eXposures) Toolkit is to provide researchers whose expertise lies outside a particular area with key measures identified by experts for uniform use in large-scale genetic studies and other extensive epidemiologic efforts going forward. The current paper specifically addresses the PhenX Toolkit research domain of(More)
