Highly reflective roofing systems have been analyzed over several decades to evaluate their ability to meet sustainability goals, including reducing building energy consumption and mitigating the urban heat island. Studies have isolated and evaluated the effects of climate, surface reflectivity, and roof insulation on energy savings, thermal load mitigation and also ameliorating the urban heat island. Other sustainable roofing systems, like green-roofs and solar panels have been similarly evaluated. The motivation for the present study is twofold: the first goal is to present a method for simultaneous evaluation and inter-comparison of multiple roofing systems, and the second goal is to quantitatively evaluate the realized heating and cooling energy savings associated with a white roof system compared to the reduction in roof-top heat flux. To address the first research goal a field experiment was conducted at the International Harvester Building located in Portland, OR. Thermal data was collected for a white roof, vegetated roof, and a solar panel shaded vegetated roof, and the heat flux through these roofing systems was compared against a control patch of conventional dark roof membrane. The second research goal was accomplished using a building energy simulation program to determine the impact of roof area and roof insulation on the savings from a white roof, in both Portland and Phoenix. The ratio of cooling energy savings to roof heat flux reduction from replacing a dark roof with a white roof was 1:4 for the month of July, and 1:5 annually in Portland. The COP of the associated chillers ranges from 2.8-4.2, indicating that the ratio of cooling energy savings to heat flux reduction is not accounted for solely by the COP of the chillers. The results of the building simulation indicate that based on energy savings alone, white roofs are not an optimal choice for Portland. The benefits associated with cooling energy savings relative to a black roof are offset by the winter-time penalty, and the net benefit from adopting white roof technology in Portland is small. That said, there are other potential benefits of white roofing such as impact on urban heat islands and roof life that must also be considered.

The purpose of this study was to examine the perceptions of families receiving the Child Support Grant in Phoenix, Durban and to establish whether the Child Support Grant contributes to poverty alleviation or not. The investigation included establishing whether people who receive the child support grant are able to meet the needs of their child, to document the income, expenditure on households receiving the child support grant, to explore whether the recipients believe that the quality of their life has improved after receiving the Child Support Grant, to ascertain what would be their ideal social security support and to determine the grant holders opinions about the termination of the grant. Fifty Child Support Grant recipients were interviewed and a questionnaire consisting of fourteen questions were completed and analysed. The results of the study indicate that the Child Support Grant has contributed significantly towards poverty alleviation in the Phoenix community. / Thesis (M.A.)-University of KwaZulu-Natal, Durban, 2004.

abstract: Monsoon hazards routinely affect the community, economy, and environment of the American Southwest. A common link for hazard development during the North American Monsoon concerns the interplay between temperature, moisture, and wind in the vertical atmosphere controlled by an unstable monsoon circulation. This dissertation investigates vertical atmospheric patterns using in-situ sounding data, specifically, 1) environments favorable for severe hail on the Colorado Plateau, 2) significant parameters distinguishing unhealthy versus healthy ozone days in Phoenix, Arizona, and 3) vertical profile alignments associated with distinct ranges in ozone concentrations observed in Phoenix having defined health impacts. The first study (published in the Journal of the Arizona-Nevada Academy of Science) determines significant variables on Flagstaff, Arizona 12Z rawinsonde data (1996-2009) found on severe hail days on the Colorado Plateau. Severe hail is related to greater sub-300 hectopascals (hPa) moisture, a warmer atmospheric column, lighter above surface wind speeds, more southerly to southeasterly oriented winds throughout the vertical (except at the 700 hPa pressure level), and higher geopotential heights. The second study (published in Atmospheric Environment) employs principal component, linear discriminant, and synoptic composite analyses using Phoenix, Arizona rawinsonde data (2006-2016) to identify common monsoon patterns affecting ozone accumulation in the Phoenix metropolitan area. Unhealthy ozone occurs with amplified high-pressure ridging over the Four Corners region, 500 hPa heights often exceeding 5910 meters, surface afternoon temperatures typically over 40°C, lighter wind speeds in the planetary boundary layer under four ms-1, and persistent light easterly flow between 700-500 hPa countering the daytime mountain-valley circulation. The final study (under revision in Weather and Forecasting) assesses composite atmospheric sounding analysis to forecast Air Quality Index ozone classifications of Good, Moderate, and collectively categories exceeding the U.S. EPA 2015 standard. The analysis, using Phoenix 12Z rawinsonde data (2006-2017), identifies the existence of “pollutant dispersion windows” for ozone accumulation and dispersal in Phoenix. Ultimately, monsoon hazards result from a complex and evolving vertical atmosphere. This dissertation demonstrates the viability using available in-situ vertical upper-air data to anticipate recurring atmospheric states contributing to specific hazards. These results will improve monsoon hazard prediction in an effort to protect public and infrastructure. / Dissertation/Thesis / Doctoral Dissertation Geography 2019

abstract: Tempe experienced rapid growth in population and area from 1949 to 1975, stretching its resources thin and changing the character of the city. City boosters encouraged growth through the 1950s to safeguard Tempe’s borders against its larger neighbor, Phoenix. New residents moved to Tempe as it grew, expecting suburban amenities that the former agricultural supply town struggled to pay for and provide. After initially balking at taking responsibility for development of a park system, Tempe established a Parks and Recreation Department in 1958 and used parks as a main component in an evolving strategy for responding to rapid suburban growth. Through the 1960s and 1970s, Tempe pursued an ambitious goal of siting one park in each square mile of the city, planning for neighborhood parks to be paired with elementary schools and placed at the center of each Tempe neighborhood. The highly-publicized plan created a framework, based on the familiarity of public park spaces, that helped both long-time residents and recent transplants understand the new city form and participate in a changing community identity. As growth accelerated and subdivisions surged southward into the productive agricultural area that had driven Tempe’s economy for decades, the School-Park Policy faltered as a planning and community-building tool. Residents and city leaders struggled to reconcile the loss of agricultural land with the carefully maintained cultural narrative that connected Tempe to its frontier past, ultimately broadening the role of parks to address the needs of a changing city. / Dissertation/Thesis / Masters Thesis History 2019
