Research has demonstrated that temperature and relative humidity substantially influence overall perceptions of indoor air quality (Fang, Clausen, & Fanger, 1998). This finding places temperature quality as a high priority, especially for vulnerable adults over 60. Temperature extremes and fluctuation, as well as the perception of those conditions, affect physical performance, thermal comfort and health of older adults (Chatonnet & Cabanac, 1965, pp. 185-6; Fumiharu, Watanabe, Park, Shephard, & Aoyagi, 2005; Heijs & Stringer, 1988). The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and the International Organization for Standardization (ISO) have developed thermal-comfort standards for working-age, healthy individuals. None of these standards address the physiological and psychological needs of older adults (ASHRAE Standard 55, 2010; ISO-7730, 2005). This dissertation investigates the impacts of thermal conditions on self-reported health and perceived comfort for older adults, hypothesizing that warmer and more-table indoor thermal conditions will increase the health and perceived comfort of these adults. To this end, a new set of thermal comfort metrics was designed and tested to address the thermal preferences of older adults. The SENIOR COMFORT Metrics 2013 outlined new thresholds for optimal indoor high and low temperatures and set limits on thermal variability over time based on the ASHRAE-55 2010 model. This study was conducted at Sunnyslope Manor, a multi-unit, public-housing complex in the North Phoenix. Nearly 60% (76 of 118) of the residents (aged 62-82) were interviewed using a 110-question, self-reporting survey in 73 apartment units. A total of 40 questions and 20 sub-questions addressing perceptions of comfort, pain, sleep patterns, injuries, and mood were extracted from this larger health condition survey to assess health and thermal comfort. Indoor environmental thermal measurements included temperature in three locations: kitchen, living area, and bedroom and data were recorded every 15 minutes over 5 full days and 448 points. Study results start to indicate that older adults for Sunnyslope Manor preferred temperatures between 76 and 82.5 degrees Fahrenheit and that lower temperatures as outlined by ASHRAE-55 2010 increases the rate of injuries and mood changes in older adults among other findings.

This study is an initial step in exploring how urban design typologies can help inform community asset research to broaden the definition of physical assets. Asset based community development research identifies specific types of physical assets such as streets, structures, housing or vacant lots. This research argues that a comprehensive look at physical assets is needed, taking into consideration urban typologies such as paths, landmarks, views and districts as well as the spatial relationships that influence their significance. Community asset literature and conditions specific to the Sunnyslope community in Phoenix, Arizona suggest that differences in ethnicity such as spatial segregation, and socio-economic status exist. However, the literature does not address how these differences in ethnicity might influence residents' perceptions of physical assets. This study explores the questions - How do perceptions of physical assets vary among women of different ethnicities? What, if any, are the reasons behind these ethnic differences in perception? The research applied a survey instrument with open-ended and close-ended questions, and a map to mark frequently used routes. Assets identified by recoding open-ended responses were statistically analyzed for frequencies. The most frequently mentioned assets were analyzed by GIS for spatial relationships. Women of White and Latino ethnicities frequently chose individual buildings and locations as physical assets over paths, views, districts and landmarks. White women identified urban typologies as physical assets. In contrast, Latino women identified no significant urban typologies as assets. The inclusion of urban typologies confirmed and expanded upon physical assets previously identified by other asset-based studies on the community of Sunnyslope. Notable differences in ethnicity were found in the perception of physical assets of economic significance, assets for use and assets of visual appeal. Besides ethnicity, age and proximity to assets also influenced asset perception of White and Latino women. Community organizations need to take into consideration the ethnic differences in perception of physical assets, in the context of culture, spatial segregation and differing family structures. The inclusion of urban typologies helped highlight the differences in ethnicities for physical assets of visual appeal, and the use of leisure and recreation facilities.

This dissertation examines the conditions that foster or hinder success of university-based community design centers (CDCs) in the United States. Little is known about the normative underpinnings of CDCs, how successful these centers have been, which factors have contributed to or impeded their success, and how they have responded to the changes in social, political, professional and economic contexts. Adopting Giddens' theory of structuration as a research framework, this study examined CDCs via a mixed-methods sequential research design: a cross-sectional survey of CDCs on current definitions of success and metrics in use; and in-depth interviews to document the centers' histories of change or stasis, and how these changes influenced their successes. The findings of the first phase were utilized to develop a comprehensive success model for current CDCs that comprise measures related to organizational impacts, activities, and capacities. In the multiple case study analysis, four major rationales were identified: universities for public service, pragmatist learning theories, civic professionalism, and social change. These four rationales were evident in all of the studied cases at varying degrees. Using the concept of permeability, the study also exemplified how the processes of CDCs had transformative impacts in institutional, societal, and personal contexts. Multidisciplinarity has also emerged as a theme for the current organizational transformations of CDCs. The main argument that emerged from these findings is that it is not possible to identify a singular model or best practice for CDCs. The strengths and unique potentials of CDCs depend on the alternative rationales, involved agencies, and their social, political and spatial contexts. However, capitalizing on the distinctive attributes of the institutional context (i.e. the university), I consider some possibilities for university-based CDCs with an interdisciplinary structure, pushing the professional, curricular, and institutional boundaries, and striving for systemic change and social justice. In addition to contributing to the theoretical knowledge base, the findings provide useful information to various CDCs across the country, particularly today as they struggle with financial constraints while the community needs they provide are increasingly in demand. Since CDCs have a long history of community service and engagement, the findings can inform other university-community partnerships.
