Study Description. The goal of the study is to perform an information synthesis to support development of a selenium monitoring program for North San Francisco Bay. The synthesis will support an integrated and strategic approach to monitoring in support of the selenium TMDL. Specific items to be covered include examination of the linkages between the three indicators (i.e., water column, sediment, and tissue), completing the development of the statistical framework for monitoring design and data evaluation, and consideration of analytical methods for long-term monitoring.
Study Description. This study will synthesize information from the DMMO database to evaluate PCB concentrations from dredging projects to compare the concentration ranges to other areas (e.g., open water and margin ambient sites), and to estimate the PCB mass removed from the Bay by dredging. The DMMO maintains a database that compiles sediment chemistry testing data from all Bay dredging projects. The DMMO has only recently released this database to the public. These data would provide valuable information to confirm the PCB total maximum daily load (TMDL) assessment that dredging results in a net PCB loss from the Bay and to leverage data already collected to evaluate the current conceptual model of Bay PCBs.

Study Description. The FTC plans to conduct Internet- based consumer research to explore consumer perceptions of certain fuel economy claims to enhance the Commission’s knowledge of how consumers understand such claims. Specifically, using a treatment-effect methodology, the proposed study will compare participant responses regarding their understanding of a variety of claim types, such as general fuel economy claims (e.g., ‘‘this car gets great gas mileage’’), specific MPG claims (e.g., ‘‘39 mpg’’), and driving range claims. To economy advertising and to facilitate aid in developing possible changes to the Fuel Economy Guide, FTC staff will
Study Description. This study was conducted using data from the InvolveMENt study, a recently completed, prospective cohort study.[24, 25, 26] The Emory University-‐led study was comprised of a computer-‐ based questionnaire and HIV/STI testing of black and white metro Atlanta MSM, and has current Emory University IRB approval. Venue sampling and convenience sampling through Facebook were used to recruit black and white MSM for the study. A variety of venues throughout Atlanta where MSM congregate were randomly chosen, and at the venues study staff systematically approached men to administer screening questions. Facebook sampling was achieved through paid advertisements directed towards men who were possibly eligible for the study. Recruitment took place between June 2010 and December 2012 during 605 sampling events at 94 individual venues. Eligibility requirements included being male at birth, being capable of completing the study instruments in English, self-‐reported white or black race, currently living in the metropolitan Atlanta area, having at least one male sex partner in the last three months, being 18 years of age or older, and providing at least two means of contact. Exclusion criteria included reporting Hispanic or Latino ethnicity, having plans to move out of Atlanta within the next two years, being in a mutually monogamous relationship with a man, or currently participating in any HIV prevention research study. Participants completed a computer assisted self-‐interview questionnaire at the baseline visit that included questions pertaining to demographics, psychosocial scales, community characteristics, individual-‐level HIV-‐related behaviors, and a dyadic inventory of the five most recent sex partners. Participants were also screened for HIV antibodies at each visit. At the baseline visit, participants were tested for syphilis, chlamydia, and gonorrhea. In addition, all participants were screened for biological markers of marijuana, cocaine, morphine, amphetamines, and methamphetamines at baseline. All participants who were confirmed to be HIV-‐negative at the baseline visit were then followed prospectively for two years to observe HIV and STI incidence. Those eligible returned for visits at 3, 6, 12, 18, and 24 months after the baseline visit, and the follow-‐up visits were conducted essentially the same as the baseline visit. Study participation ended after the 24-‐month visit or after HIV seroconversion.
Study Description. A cross-sectional qualitative study was conducted to explore the barriers and facilitators to participation in MtMSGs in northern Sierra Leone. The research was conducted in three stages. Figure 5 diagrams the series of research activities that were undertaken for this study. In stage one, doer/ non-doer surveys were conducted to explore the differences between women who attend support groups with those who do not, to gain insight on women’s perceptions toward MtMSGs and who women saw as influential parties in decision making. Stage two consisted of decision trees, social mapping, and ten seed analyses. These activities were conducted to explore where women go to obtain IYCF information, the barriers and facilitators to attending MtMSGs and to further refine the research questions used for focus group discussions and key informant interviews. In stage three, 16 focus groups and 10 key informant interviews were conducted to explore the cultural and programmatic barriers and facilitators to participation and understanding of community perceptions of MtMSGs.

Study Description. The calculation and monitoring of sediment loads entering San Francisco Bay are important for a variety of reasons, such as to inform dredging and tidal wetland restoration projects and to assess aquatic ecology, among others. While the information on sediment loads from many tributary sources is up-to-date, for other areas, such as the North Bay watersheds, there is little or no recent data. The objective of the work proposed herein, which the San Francisco Estuary Institute (SFEI) will carry out through the Regional Monitoring Program for Water Quality in San Francisco Bay (RMP) under Regional Water Board oversight, is to address this data gap by monitoring sediment loads at two existing USGS gages in the North Bay watersheds: 11458000 NAPA R NR NAPA CA, and 11458500 SONOMA C A AGUA CALIENTE CA. These two existing USGS gages currently monitor water flow rates following standard USGS methods. The addition of sediment load monitoring at these two gages is particularly important now because it will also provide information on sediment loads following the recent and extensive North Bay fires in these watersheds. Both gages have burned areas upstream. For this reason, it is critical that the monitoring begin as soon as possible. The scope and budget of this study assumes that the ongoing water flow rate monitoring at both sites will continue. The study will employ the following methods:
Study Description. This study is a prospective comparative, randomized, single center study to gather agreement and precision of the Nidek Xxxxxxx OCT with SLO and Anterior Segment Imaging capabilities in comparison to the Optovue RTVue XR Avanti OCT and Optos P200DTx in normal subjects, subjects with glaucoma, subjects with retinal disease and subjects with corneal disease.
