"We learn from them, they learn from us": global health experiences and host perceptions of visiting health care professionals.

PURPOSE: It is increasingly common for health care professionals from developed countries to travel to developing regions of the world to learn or teach. This project aimed to describe the perceptions held by health care professionals in a developing region toward those who visit their communities to learn or teach. METHOD: Semistructured interviews were conducted in July, 2011, with nine health care professionals from the University of Namibia School of Medicine. Questions revolved around participants' perceptions of benefits, harms, and ethical impressions of a health care professional visiting from a developed country. Interviews were tape-recorded, transcribed, and analyzed qualitatively using an inductive, iterative approach. RESULTS: The interview analysis identified three main narratives that shaped participant perceptions of visits: (1) culture, context, and concern, (2) expectations, intentions, and miscommunications, and (3) partnership and the desire to share and gain knowledge. CONCLUSIONS: Participants' comments supported actively seeking out information regarding cultural and environmental context before visiting, completing a needs assessment to ensure that activities are needed and relevant, attempting to formulate long-term sustainable relationships, and traveling with the appropriate attitude. These themes provide valuable insight into how international educational collaborations can be created in order to be mutually beneficial

The propulsion control requirements of supersonic aircraft are presented. Integration of inlet, engine, and airframe controls is discussed. The application of recent control theory developments to propulsion control design is described. Control component designs for achieving reliable, responsive propulsion control are also discussed

Large Dog Relinquishment to Two Municipal Facilities in New York City and Washington, D.C.: Identifying Targets for Intervention

While the overall trend in euthanasia has been decreasing nationally, large dogs are at a higher risk of euthanasia than other sized dogs in most animal shelters in the United States. We hypothesized one way to increase the lives saved with respect to these large dogs is to keep them home when possible. In order to develop solutions to decrease relinquishment, a survey was developed to learn more about the reasons owners relinquish large dogs. The survey was administered to owners relinquishing their dogs at two large municipal facilities, one in New York City and one in Washington, D.C. There were 157 responses between the two facilities. We found both significant similarities and differences between respondents and their dogs from the two cities. We identified opportunities to potentially support future relinquishers and found that targets for interventions are likely different in each community

Mathematical Model of Heavy Metal Transfer and Transport in Lake Erie

This study was supported in part by the Office of Water Resources Technology, U.S. Department of Interior under project A-045-OHIO(print) vii, 141 p. : ill. ; 27 cm.Numerical integration of mathematical functions representing the concentration of mercury, chromium and nickel in Lake Erie sediments indicate that 3.3 x 10^5 kg Hg, 1.8 x 10^7 kg Cr, and 1.2 x 10^7 kg Ni have been added to the sediments through man's activities. Most of the mercury, chromium and nickel are contained in the sediments of western Lake Erie. A mathematical model of sediment transport in Lake Erie shows that most of the heavy metals in western Lake Erie sediments probably originated from the Detroit metropolitan area and was input via the Detroit River. The sediment dispersal patterns are as follows: 1) the Detroit River sediment spreads southeastward over most of the western basin, 2) the Maumee River sediment is held within 15 miles of the Ohio shore, and 3) the Cuyahoga River sediment travels northeastward along the south shore of the lake. Attempts to model the transfer and transport of mercury within the ecosystem resulted in partial success. Very little transfer results between the sediments and other phases within the system. In contrast the exchange of mercury between the benthic organisms and other trophic and abiotic levels is very rapid.Abstract -- Key Words -- Project Personnel -- Introduction -- Mercury, Chromium and Nickel in Lake Erie Sediments -- Sediment Transport Model -- Model of Mercury Transfer and Transport in Lake Erie - Appendice

Predicted Colors and Flux Densities of Protostars in the Herschel PACS and SPIRE Filters

Upcoming surveys with the Herschel Space Observatory will yield far-IR photometry of large samples of young stellar objects, which will require careful interpretation. We investigate the color and luminosity diagnostics based on Herschel broad-band filters to identify and discern the properties of low-mass protostars. We compute a grid of 2,016 protostars in various physical congurations, present the expected flux densities and flux density ratios for this grid of protostars, and compare Herschel observations of three protostars to the model results. These provide useful constraints on the range of colors and fluxes of protostar in the Herschel filters. We find that Herschel data alone is likely a useful diagnostic of the envelope properties of young starsComment: Part of HOPS KP papers to the Herschel special A&A issu
