      Burross, John Marcus, 1946- (The University of Arizona., 1975)
    • Survey: attitudes of military pharmacists toward drug information center support

      Jenkins, Leslie Gail "Rick" (The University of Arizona., 1980)
    • Survivability in air vs. ground transported trauma patients

      Crosby, Leanna J.; Higie, Stephanie Marie (The University of Arizona., 1993)
      Helicopter Emergency Medical Service (EMS) programs have shown a steady pattern of growth over the last 20 years. The impact of hospital-based helicopter EMS programs, on the survival of trauma patients has been evaluated by several investigators with conflicting results. The purpose of this study was to compare the survivability of trauma patients flown by helicopter versus the survivability of trauma patients transported by ground vehicle to a Level I Trauma Center. 11 The second purpose of the study was to determine the relationship between survivability and 1) age, 2) mechanism of injury, 3) severity of injury, and 4) physiologic insult in a population of trauma patients flown by helicopter to a Level I Trauma Center, and a population of trauma patients transported by ground vehicle to a Level I Trauma Center. Chi Square tests of statistical independence were used to analyze the data. Air transported patients were found to have statistically significantly higher injury severity scores, and a higher mortality rate. A blood pressure of < 80, age of > 54, and penetrating injury were also found to negatively impact survival.
    • The survival and recovery of Salmonella in Tucson's wastewater reclamation program

      Butler, Clifford Edison,1931-; Ludovici, Peter P. (The University of Arizona., 1968)
      An investigation into the survival and recovery of Salmonella and Shiella in Tucson's wastewaters was conducted as one aspect of a program dealing with the use of a pilot soil fitter to reclaim water from secondary treated sewage. Only a rare Salmonella and no Shigella were detected in the sewage or activated sludge effluents. When Salmonella typhimurium was added to wastewaters, recovery was dependent on the number of indigenous organisms. Salmonella typhimurium could not be recovered from sewage when the ratio of added Salmonella to indigenous organisms was 1:500,000 per ml. When the ratio was 1:50,000 per ml, Salmonella typhimuriurn was recoverable. When the indigenous organisms were removed by membrane filtration or reduced by high-speed centrifugation, added Salmonella typhimurium or Shigella flexneri not only survived but increased 2 to 5 logs in 24 hours.
    • Survival and spreading ability of endemic and exotic grasses on a desert grassland site

      Claverán Alonso, Ramón, 1934- (The University of Arizona., 1965)
    • Survival distancing: A grounded theory of living with HIV infection in rural areas

      Longman, Alice J.; Gray, Joel Ronald, 1962- (The University of Arizona., 1994)
      A disparity of resources for HIV-infected persons exists in rural areas. Unlike any other chronic illness, HIV has no immediate medical intervention until significant disease progression occurs. Lack of curative treatment for a disease process known to induce irrevocable damage to the immune system causes distress, anxiety, and uncertainty. Presently, no theory exists to aid health professionals understand and provide appropriate interventions for these individuals. Considering the negative effects of stress and illness on immune function and the inadequacy of health care services, the purpose of this study was to identify experiences of HIV-infected persons in rural areas. S scURVIVAL D scISTANCING, described experiences by which HIV-infected persons in rural areas balanced limits and accepted the reality of living with chronic illness. Migration of HIV-infected persons, in addition to those indigenous to rural areas, added to challenges in determining health care needs of those infected and needs of those affected by HIV.
    • Survival of Microbial Indicators In constructed Wetlands

      Vinluan, Edlin Artuz.; Gerba, Charles P. (The University of Arizona., 1996)
      The purpose of this study was to evaluate the removal of bacterial and viral indicators in a constructed wetland system receiving secondarily treated sewage. Results along a multispecies raceway showed that coliphage and enteric bacteria were removed similarly. Among the enteric bacteria, fecal coliforms were removed to a greater extent than total coliforms and enterococci. No differences were observed in the survival of total coliforms in sunlight or shade. Fecal coliform inactivation, however, occurred more readily in the shade than in sunlight. The inactivation of PRD-lwas the same in either sunlight or shade. However, MS-2 was inactivated more readily in the shade than in sunlight. PRD-1 was more resistant to inactivation than MS-2. Laboratory survival experiments revealed that all tested indicators were more rapidly inactivated at 37°C than at 25° C. At 4° C, however, MS-2, PRD-1, and indigenous coliphage remained relatively stable after 32 days. Among the three, PRD-1 seemed to be the most stable. When exposed to direct sunlight at a constant temperature, PRD-1 was inactivated more rapidly than both fecal coliforms and indigenous coliphage.
    • The survival of velvet mesquite (Prosopis juliflora var. velutina) after fire

      Blydenstein, John, 1929- (The University of Arizona., 1957)
    • Survival status of elderly nursing home residents following involuntary relocation

      Woodtli, Anne; Ehrmann-Vanderbilt, Irine, 1932- (The University of Arizona., 1993)
      Survival status of 45 elderly skilled nursing care residents was examined over a 42 month period following involuntary interinstitutional relocation. Medical and relocation planning records provided data to examine survival status of residents in relation to focal and contextual stimuli. Results were compared to a relocation study previously conducted in the same community. Significant relationships existed between survival status and family support and participation in relocation planning event. A higher percentage of subjects survived who did not have family support and did not participate in planning events. A significant relationship was found between time intervals in which deaths of male and female subjects occurred. In the first nine months, 13 of 14 males died; six of the 14 females died. No significant relationships were found between survival status and age, gender, mobility, or dementia. Findings suggest the need for continued study of variables affecting survival status of relocated elders.
    • Surviving the storm: The experience of Desert Storm nurses

      Longman, Alice J.; Concannon, Kathleen O'Sullivan, 1958- (The University of Arizona., 1992)
      Military nurses are often faced with uncertainty in their careers. The potential for deployment raises several concerns: family security, personal safety, and appropriate training to meet the requirements of deployment. Effectively managing these concerns necessitates coping skills and a supportive environment. Using grounded theory, three Air Force nurses were interviewed about their experience of deployment in support of Desert Shield/Storm. From these interviews, a theory emerged of Camaraderie, Patriotism, and Personal Growth as defining the experience. Camaraderie had three dimensions: Physical, Emotional, and Psychological. Despite the stressors encountered throughout the period of time deployed, the experience was described as an overall positive event. This study was an initial attempt to define the experience of deployment. Nurses facing future deployments could use this theory to design supportive processes to ensure a positive experience.
    • Surviving The Virtual: Crafting A New Form Of Theater For The Digital Age

      Ford, Vanessa Anne; Dickey, Jerry (The University of Arizona., 2006)
      This thesis proposes a new genre of theater that combines participatory and interactive narratives with virtual reality technologies and traditional theatrical elements to create a form that is capable of responding to the growing desire for interactive entertainment mediums. A series of participatory narrative events, including traditional theater productions, interactive narrative/drama and role-playing games, are analyzed for their potentialities and limitations. These elements are then used to respond to scholarly writings concerning the problems of participatory narrative forms. From this analysis conclusions are drawn about the necessary elements needed to create this new genre of theater, termed interactive virtual theater, or IVT. The elements are then synthesized into a hypothetical picture of what the IVT of the future might look like.

    • Suspended sediment yields for selected watersheds in western Montana

      Hawkins, Richard H.; Laprevote, James Arthur; Hawkins, Richard H. (The University of Arizona., 1997)
      Annual suspended sediment yields for 17 watersheds in western Montana in a mild drought are recalculated. Previous methodology used sporadic to weekly direct measurements taken only during the annual snowmelt during the drought to estimate drought period yields. Yield approximations for wet period flows relied on predicted increases in the means of flow and sediment concentration of the measured values. This study uses synthetic flow duration curves developed using regional data of a longer period of record for drought and wet period estimates. These are combined with log-transformed sediment rating curves which are bias corrected. Mean flows for the drought average of half previous calculations, sediment yields average 70 percent less. The bias correction averages + 33 percent. Estimates of sediment yield due to increases in flow are 60 percent less than previous approximations.
    • Sustainability Toolkit: An Education Tool for Behavioral Change Strategies

      Chalfoun, Nader; Gardner, Ambar Alexis; Chalfoun, Nader; Moeller, Colby; Youssef, Omar; Elzomor, Mohamed (The University of Arizona., 2017)
      Purpose: There is a worldwide movement towards sustainability. A stepping-stone towards a sustainability conscience population starts in the education of the younger generation. Focusing on improving sustainability education will shift and shape youths' interests and lifestyles into an educated community that will work sustainably. A sustainability conscience community will continue to make moral sustainable decisions in their future endeavors. The gap between theory and practice of sustainability is substantial. Educational institutions must be the leaders in this subject to mold future generations’ incoming leaders into sustainability conscious critical thinkers. Current environmental issues such as climate change, CO2 Emissions, poverty and so on must impact these educational institutions to make sustainability education a priority in its curriculum. Addressing this problem requires a holistic approach which integrates sustainability education earlier on to grasp further understanding of sustainability actions in higher education and in society. Sustainability education exists in all levels. Although, sustainability education is much more prominent in higher education institutions as opposed to Elementary, Middle, and High Schools. Consequently, less students are prepared with the desired sustainability knowledge needed in higher education and students' future careers to instill in their disciplines since behavior is achieved through repetitive actions that were not set as a foundation earlier in their education. Approach: There were two approaches in this research. The first research approach was conducting a survey in 120 students, half of them in secondary education and the other half in higher education. The survey was formatted to analyze three different questions: 1) whether students in high school and higher education knew about sustainability 2) whether students' lifestyle consisted of pro-environmental actions, 3) and whether they learned to perform these actions in secondary education or higher education. The second approach was to create an educational tool to implement sustainability behavioral change strategies in their everyday lifestyles. Findings: Study found that most students are aware about sustainability. However, most students engage in pro-environmental actions in higher education because they started learning about them in higher education. Therefore, although most secondary education students are aware about sustainability, they aren't engaging in pro-environmental actions. In conclusion, a sustainability toolkit was created based on behavioral change strategies to reduce water usage, CO2 emissions, energy consumption, and waste output in their school and everyday lifestyles. Value: The efforts of sustainability in Higher Education have been clear in most recent years, although, there is still much resistance to change, transform and reimagine society and education for sustainability. The future of life and social world on Earth is in jeopardy since poverty, climate change, and lack of peace is occurring worldwide. Sustainability education must respond and act on this challenge subsequently to respect all forms of life and future generations. The mission of the sustainability toolkit is to create a pedagogy to assist educational institutions and communities to develop the skills and knowledge to work sustainably.
    • Sustainable Climate Response Connectors at The University of Arizona to Improve User Performance and Reduce Carbon Footprint

      Chalfoun, Nader V.; Rojas, Cesar Alberto; Chalfoun, Nader V.; Moeller, Colby; Youssef, Omar (The University of Arizona., 2017)
      The University of Arizona Main Campus is located in the city of Tucson, Arizona. A place that confronts high air temperatures and extreme solar radiation almost all year around. Currently, more than 38,000 students are enrolled as full-time facing the extreme climate conditions of heat. Thousands of students walk from one place to another experiencing uncomfortable walks causing them heat stress. Campus infrastructure is not capable to interact with the weather conditions of Tucson. The lack of shaded paths, materials with high emissivity of heat, nonnative vegetation, among other factors, make the walks unpleasant. This challenge affects people's health and consecutively the performance of cooling systems once the people enter to buildings overheated. Outdoor human thermal comfort in arid and desert areas is a relevant topic that carries implications and benefits on people and buildings performance. The amount and intensity of activities within individuals affects the level of comfort.
    • Sustainable Design for Health Care Facilities: A Case Study of the LEED Certified Rincon Community Hospital at Civano

      Moeller, Colby; Chalfoun, Nader (The University of Arizona., 2006)
      This Master’s Report focuses on applying sustainable design principles to the design of Rincon Community Hospital at Civano a new healthcare facility being planned for Tucson. Civano is a pre-planned sustainable community located in Tucson, Arizona that demonstrates efficient utilization of resources and planning. Based upon the principle of human thermal comfort, the proposed hospital design emphasizes integration with the surrounding environment by focusing on the relationship of the indoor and outdoor spaces. This includes maximizing the effective use of adjacent open air spaces, transitional spaces, and courtyards that are designed to maximize thermal comfort by working with the local climate to create comfortable microclimates around the building. Rincon Community Hospital at Civano also demonstrates the application of Leadership in Energy and Environmental Design (LEED®) principles during the design process. The proposed design for the hospital utilizes passive solar design, daylighting, earth cooling, and building orientation to create comfortable environments for human occupation that require less energy than specified by ASHRAE Standard 90.1 1999. To achieve these goals, the hospital design was developed through analysis of the physical characteristics of the site, potential for LEED® scoring, and energy analysis. The results are presented as annotated plan, section and perspective images. It is hoped that this methodology can be applied to future development of sustainable healthcare facilities in desert environments that create healthy natural environments to aid patient healing and accelerate their recovery process.
