• Categories of elderly experience in the landscape

      Wilkin, Donovan C.; Doxtater, Rebecca Jo, 1944- (The University of Arizona., 1992)
      Aspects of landscape experience by the elderly are explored. An understanding of this user group is sought through investigation of stereotypes, personality traits, psyco-social, and physical aspects of aging. A construct of use categories provides a system for understanding the environment in terms of what it is perceived to provide its users. Use categories include wayfinding, human territoriality, cultural expression, visual and non-visual aesthetics, and task performance. Drawing from literature and research in many areas, each of these categories is first defined in general terms. Each is then surveyed relative to its more specific application to the elderly which is followed by an examination of each category as it relates to the elderly and landscape. Application of categories to site analysis, programming, design, post-occupancy evaluations, and research is proposed. Some landscape design implications for the elderly are noted along with areas for further research.
    • Perceptions of quality of life held by Tubac residents: A further exploration of qualitative approach to quality of life research

      Wilkin, Donovan C.; Mann, Hili Sonia, 1962- (The University of Arizona., 1998)
      This study explores: (1) Attitudes and perceptions of Tubac residents that may have an impact on their QOL--both personally and at the community level; and (2) QOL measurement techniques that may contribute to the utilization of QOL indicators as a tool for studying and monitoring human communities toward a sustainable future. Informal interviews were conducted with seventeen Tubac residents followed by the distribution of a questionnaire in a "snowball" sampling method (Bernard, 1994). Fifty-two responses were compiled and compared for similarities and differences. Results demonstrate the majority of Tubac residents are extremely satisfied with the QOL and feel fortunate to live in a community they believe is unique--mostly for its surrounding natural scenery. Results also support the idea that qualitative approaches to QOL measurement techniques are necessary for further comprehension of the complexities of human communities.
    • Potential Use of Water Harvesting in an Urban Development on State Urban Lands in the Tucson Area

      Gutierrez, Joni Marie.; Wilkin, Donovan C.; Hebel, Susan Jane; Cluff, Carwin Brent (The University of Arizona., 1984)
      Tucson, Arizona's population depends on its natural water supply as the largest community in the nation to rely entirely upon groundwater. With a population growth rate of 41/2 percent a year, Tucson's groundwater levels have been declining. State Urban Land, available for urban development in the Tucson area, is largely located where groundwater supplies are limited. If these lands are to be developed, insitu surface water supplies have to be utilized. This study examines an actual planned subdivision case study, Fairway Villas, along with existing water harvesting technologies. The case study and existing technologies are then incorporated into two additional schemes of design and compared. Comparisons of the potential runoff and economic feasibility were made. The two redesigned subdivision schemes indicated the runoff potential of the sites is enough to supply the subdivision with water for all landscape needs in both cases. Economically, the two additional schemes become feasible at a water rate increase of 7 and 10 percent, respectively. The State Land Department has the potential to fully develop their Urban Land near Tucson if alternative water supplies, such as water harvesting, are utilized.
    • Water in Tucson: Policy, Planning, and Public Involvement

      Hathaway, Pamela Lynne.; Ingram, Helen M.; Brickler, Stanley K.; Wilkin, Donovan C.; Gregg, R. Frank (The University of Arizona., 1984)
      This paper describes and assesses the policies, planning agencies, and citizen advisory committees which are involved in water resource decision making in the Tucson basin. Shifting priorities in basin water uses are traced by reviewing four events and trends. This review, together with a description of existing policies and planning agencies, provides the basis for assessing the status and potential for public involvement in water resource decision making. The influence of the citizens advisory committees on water resource decision making depends on the relationship among an agency, a committee, and the general public. If citizens advisory committees are to address controversial issues, such as those surrounding the priorities of water use in the basin, a link between community education and political participation is necessary.
