    Measuring HIV risk in the U.S. population aged 15–44: Results from Cycle 6 of the National Survey of Family Growth

    Objective—This report presents national estimates of the percentage and number of persons in the U.S. population aged 15–44 who report behaviors that place them at increased risk for acquiring or transmitting human immunodeficiency virus, or HIV. The report also contains data on condom use and HIV testing by persons who report risk behaviors. In addition, estimates of self-reported risk for HIV from the Cycle 6 National Survey of Family Growth (NSFG) are compared with data from other recent national surveys. Methods—Data from the NSFG Cycle 6, conducted by the Centers for Disease Control and Prevention’s (CDC) National Center for Health Statistics (NCHS), are based on interviews with a national sample of the household population of the United States. In-person, face-to-face interviews were conducted in the homes of 12,571 males and females 15–44 years of age in 2002. Most of the data were collected by Computer-Assisted Personal Interviewing (CAPI), in which a laptop computer is used to select and present the questions, which an interviewer reads to the respondent. The more sensitive data, including the risk behavior items on which this report is based, were collected by Audio Computer-Assisted Self-Interviewing (ACASI), in which the respondent listens to recording of each question and enters his or her own answers into the computer without involving an interviewer. Results—Overall, 8.9 percent of persons 15–44 years of age had engaged in sexual behaviors in the past year that put them at increased risk of HIV, and 1.5 percent had engaged in drug use behaviors that put them at risk. In all, an estimated 9.9 percent engaged in either drug use or sexual behavior that placed them at increased risk for HIV. Including those who were treated for a sexually transmitted disease (STD) in the past year, 11.9 percent of persons 15–44 years of age—13.0 percent males and 10.8 percent of females—were at risk of HIV in 2002. The 11.9 percent at risk is equivalent to an estimated 14.4 million persons aged 15–44 at higher risk of HIV through drug use, sexual behavior, or having been treated for an STD in the past year. Persons who were at increased risk reported greater condom use and higher rates of HIV testing, but among those at risk, 33.6 percent had never been tested for HIV and 60.4 percent did not use condoms at last sex

    Suggested severe local storm operational scenario for GOES I-M

    Get PDF
    The GOES I-M satellite system is expected to provide continuous high resolution estimates of temperature and moisture profiles, winds from cloud motions, surface temperature, cloud properties, and precipitation for severe local storm and tropical cyclone events. The suggested operational schedule for the GOES I-M satellite emphasizes the observation frequencies, spatial coverage, spectral bands, etc. for the GOES I-M imager and sounder instruments that are expected to optimize the determination of the relevant meteorological parameters. During severe local storm events, the imager would be programmed to perform high frequency imaging (less than or= 3.5 min) for determining winds from cloud motions and for monitoring severe convection. In addition, the sounder would provide temperature and moisture profiles every hour over a 3000 X 3000 km domain during the antecedent stage or over a 1000 X 1000 km area every 10 minutes during the mature storm stage

    Learning Together: Actionable Approaches for Grantmakers

    Get PDF
    A majority of grantmakers are struggling to make evaluation and learning meaningful to anyone outside their organizations. Not only is evaluation conducted primarily for internal purposes, but it is usually done by the grantmaker entirely on its own -- with no outside learning partners except perhaps an external evaluator -- and provides little value and may even be burdensome to the grantee. It may be that some funders do not consider expanding the scope of learning efforts beyond their own walls. Or perhaps the gap is driven by funding constraints or funder -- grantee dynamics. In any case, grantees and other stakeholders are critical partners in the achievement of grantmakers' missions and are therefore critical learning partners as well.In this publication, GEO offers actionable ideas and practices to help grantmakers make learning with others a priority. The publication includes stories about foundations that are learning together with a variety of partners, plus a discussion of the key questions that can help shape successful shared learning. It is based on research and interviews conducted from late 2013 to 2015, including extensive outreach to grantmakers, evaluation practitioners and others. The focus of GEO's inquiry: documenting the challenges facing grantmakers as they set out to learn with others, lifting up what it takes to do this work successfully and identifying grantmakers that show a commitment to learning together

    A Model for Calculating Desert Aerosol Turbidity Over the Oceans from Geostationary Satellite Data

    Get PDF
    A technique has been developed to infer the optical thickness of Saharan dust from Synchronous Meteorological Satellite (SMS) brightness measurements at visible wavelengths. The scattering model consists of an air layer, a dust layer and a lower boundary of variable albedo. Single-scatter properties of the dust computed from Mie theory were the basis for calculations by plane-parallel theory of radiative transfer in the dust layer. Radiative interactions between air and dust layers and the lower boundary were calculated with an adding version of the doubling scheme. Optical thickness was determined from satellite brightness measurements through a lookup table produced by the adding program. SMS visible sensors were calibrated from the prelaunch calibration measurements and measurements of sun and space. Error analysis and tests indicate a potential accuracy of ∼0.1 unit of optical thickness. The main limits on accuracy are digitizing resolution of the SMS visible signals, and mistaking clouds for dust in the satellite imagery. This technique of inferring Saharan dust turbidity has been verified and fine-tuned using surface turbidity measurements during GATE and corresponding SMS imagery

    Ex vivo Platelet Deposition on Fibronectin-Preadsorbed Surfaces

    Temporal platelet deposition profiles of canine plasma fibronectin (CPFN) adsorbed to different polymers ex vivo and the in vitro characteristics of CPFN adsorption were studied in an attempt to correlate the two. The maximum platelet deposition (pltmax) obtained at a protein preadsorption time of 30 min was greater than that obtained using an adsorption time of 120 min for all surfaces studied. At 30 min of preadsorption, pltmax was 520, 560 and 1230 platelets/1000 μm2 on Biomer, polyethylene (PE) and oxidized PE (OXPE), respectively. In contrast, the platelet deposition at 120 min. of fibronectin preadsorption was about 60-90 platelets/1000 μm2 on all polymers studied. The surface concentrations of adsorbed CPFN measured using 125I-CPFN, were in the order PE\u3e OXPE \u3e Biomer. The adsorbed protein concentration increased with increasing adsorption time. The surface distribution of adsorbed CPFN was visualized with antibody-labelled colloidal gold and scanning electron microscopy. The extent of staining was lowest on PE, greater on Biomer, and highest on OXPE, roughly similar to the order of platelet deposition. Platelet deposition ex vivo appears to correlate with the irnmunogold-stainable-adsorbed protein rather than with the total amount of adsorbed protein
