Sociology & Criminal Justice Faculty Publications

Diffusion of innovation (DOI) is widely cited in the HIV behavior change literature; however there is a dearth of research on the application of DOI in interventions for sex workers. Following a randomized-controlled trial of HIV risk reduction among female entertainment workers (FEWs) in Shanghai, China, we used qualitative approaches to delineate potential interpersonal communication networks and contributing factors that promote diffusion of information in entertainment venues. Results showed that top-down communication networks from the venue owners to the FEWs were efficient for diffusion of information. Mammies/madams, who act as intermediaries between FEWs and clients form an essential part of …

Biodosepr-2006 Consensus Committee Report On Biodosimetric Methods To Evaluate Radiation Doses At Long Times After Exposure, Steven L. Simon, Ian Bailiff, André Bouville, Paola Fattibene, Ruth A. Kleinerman, David C. Lloyd, Stephen W.S. Mckeever, Alexander Romanyukha, Alexander V, Sevan’Kaev, James D. Tucker, Albrecht Wieser

Uniformed Services University of the Health Sciences

The requirements for biodosimetric techniques used at long times after exposure, i.e., 6 months to more than 50 years, are unique compared to the requirements for methods used for immediate dose estimation. In addition to the fundamental requirement that the assay measures a physical or biologic change that is proportional to the energy absorbed, the signal must be highly stable over time to enable reasonably precise determinations of the absorbed dose decades later. The primary uses of these biodosimetric methods have been to support long-term health risk (epidemiologic) studies or to support compensation (damage) claims. For these reasons, the methods …

Evaluation Of The Biological Sampling Kit (Biskit) For Large-Area Surface Sampling, Mark P. Buttner, Patrica Cruz, Linda Stetzenbach, Amy Klima-Comba

Environmental & Global Health Faculty Research

Current surface sampling methods for microbial contaminants are designed to sample small areas and utilize culture analysis. The total number of microbes recovered is low because a small area is sampled, making detection of a potential pathogen more difficult. Furthermore, sampling of small areas requires a greater number of samples to be collected, which delays the reporting of results, taxes laboratory resources and staffing, and increases analysis costs. A new biological surface sampling method, the Biological Sampling Kit (BiSKit), designed to sample large areas and to be compatible with testing with a variety of technologies, including PCR and immunoassay, was …

Validation Of A Bag Sampling Method For 1,3-Butadiene, Lori Eckenrode

Community & Environmental Health Theses & Dissertations

At this time there is no NIOSH approved means for bag sampling 1,3-butadiene. An attempt was made to use the application of cold (0°F) to inhibit the reactivity of the gas prior to analysis. The State of California Air Resources Board has an approved method for the gas chromatographic analysis of 1,3-butadiene from stationary sources. The method was utilized in the application of industrial hygiene monitoring of affected workers. The application of cold was found to be ineffective at inhibiting the highly reactive nature of 1,3-butadiene. Analyte losses were too great to classify the method as an accurate measure of …

Analysis And Evaluation Of The Workplace Exposure Assessment Workbook Developed By Keith Tait Including Some Recommended Revisions, Lisa Hebberd

UNLV Theses, Dissertations, Professional Papers, and Capstones

Some risk due to the contamination of workplace environments is an inevitable part of human lives. These risks can often be reduced by improving the control of environmental pollution in the workplace. An extremely important challenge for any industry is to develop a mechanism to identify acceptable levels of safety, or "acceptable risk" in the workplace for specific situations, and to assure adequate quality control over measured or calculated exposure concentrations and their possible contributions to adverse health effects.

Dry aerosols containing known concentrations of Penicillium chrysogenum spores were generated, and air samples were taken by using Andersen six-stage, Surface Air System, Burkard, and depositional samplers. The Andersen and Burkard samplers retrieved the highest numbers of spores compared with the measurement standard, …

Evaluation Of Four Aerobiological Sampling Methods For The Retrieval Of Aerosolized Pseudomonas Syringae, Mark P. Buttner, Linda Stetzenbach

Environmental & Global Health Faculty Research

The Andersen six-stage impactor, the SAS (Surface Air System) impactor, the AGI-30 impinger, and gravity plates were evaluated for the retrieval of aerosol-releasedPseudomonas syringae. The upper limits of the impactor samplers were exceeded at a spray concentration of 10^7 CFU/ml, indicating that these samplers are not appropriate for monitoring high airborne concentrations. Decreased cell concentrations were retrieved with increased sampling time for the Andersen and AGI samplers, indicating that a minimum sampling time is preferable for monitoring aerosolized vegetative cells.

Effects Of Applied Soil Repellent Finish On Pesticide Residues In Work Clothing, Sandra L. Prior

Community & Environmental Health Theses & Dissertations

This study explores the feasibility of using an applied soil repellent finish, Scotchgard, on 100% cotton denim fabric in order to enhance the removal of atrazine and alachlor residue during the laundering process. The experimental findings provided no statistically significant evidence that Scotchgard fabric protector reduced pesticide residuals on the 100% cotton denim fabric either before or after laundering. A significant finding secondary to the study involved the possible interaction of Scotchgard with the pesticide alachlor, leaving greater amounts of residual on the fabric after laundering than those found with no fabric treatment. This suggests that agricultural workers be cautioned …
