A Thesis submitted to The University of Arizona College of Medicine - Phoenix in partial fulfillment of the requirements for the Degree of Doctor of Medicine. / Background: One out of every three cancer diagnoses is a skin cancer, and the incidence of both melanoma and non‐melanoma type skin cancers is increasing. Skin cancers, including melanoma, are typically treatable if detected early. However, there is insufficient evidence to support recommendations to establish population based skin cancer screening programs. The specific aims of this study are 1) to evaluate characteristics of participants who attend a community skin cancer screening event and who are referred for follow up due to suspicious lesions, 2) to determine the proportion of participants with suspicious lesions identified at a community skin cancer screening event who complied with a request to visit a dermatologist or primary care physician, and 3) to evaluate attitudes toward sun protection practices, and perceived risk of developing skin cancer among participants who attend a community skin cancer screening and have a suspicious skin lesion. Methods: The Skin Cancer Institute sponsored a series of community skin cancer screening events in Tucson, Arizona from 2006 to 2013. Participants completed an American Academy of Dermatology screening form prior to a skin examination by a dermatologist. Participants with suspicious lesions identified at the examination who agreed to be contacted again received questionnaires 4 months after the initial screening to assess compliance with follow‐up recommendations, and their sun protection practices and risk perceptions. Results: 1979 community members attended the skin cancer screenings. The majority of the participants were Caucasian, females, had blue eyes and brown hair, were college educated, had no prior personal or family history of skin cancer, had health insurance but did not have a regular dermatologist, reported that they had never been to a skin cancer screening before, and stated that without this screening that they would not have their skin examined. 748 (37.8%) of community members were referred and instructed to see a dermatologist for further evaluation of a skin lesion. Of the 441 participants with a suspicious lesion who consented to participate in the follow‐up study, 120 returned a questionnaire; 90 (75%) reported that they followed up with a dermatologist or physician, and 30 (25%) did not. Of the 90 participants who followed up, 53% received a skin biopsy. The self reported diagnoses from the biopsies of the suspicious skin lesions were the following: 1% atypical or dysplastic nevus, 21% actinic keratosis, 16% basal cell carcinoma, 8% squamous cell carcinoma, 2% melanoma, and 38% did not have skin cancer. Conclusions/Impact: This study demonstrated that 38% of community skin cancer screening participants were referred for follow up due to a suspicious skin lesion being identified during a skin cancer screening event. It also appeared that 75% of those who responded to the follow‐up questionnaire complied with the request within four months, although the response rate for the follow‐up questionnaire was low. Therefore, implementing a formal reminder system following the skin cancer screenings may increase the percentage of participants who follow up with a primary care physician or dermatologist after the screening for further evaluation of their suspicious skin lesion.

A three-part study was conducted to characterize and assess the impact of subterranean termite infestation of urban structures in Tucson, Arizona. A termite control questionnaire was administered to all Tucson-based pest control firms offering termite control services, of which 52 percent responded. Twelve study sites were established in and around the city, with toilet paper rolls serving as termite bait at each site. In addition, 5943 active termite control contracts were accessed from Tucson's largest pest control company, and analyzed with accompanying data from various sources including those pertinent to structure location, construction, treatment history, and surrounding soil types. An estimate of over $3 million for gross annual income derived from commercial termite control services performed in Tucson, was calculated from questionnaire responses. Termide (heptachlor + chlordane) was the most frequently used termiticide. Approximately 45 percent of commercial termite control jobs were performed with Termide, the principal termiticide used by 85.7 percent of companies offering termite control services. Gnathamitermes perplexus (Banks) was most prevalent in the toilet paper rolls at bait sites, followed by Heterotermes aureus (Snyder) and Reticulitermes tibialis Banks. G. perplexus infested bait at sites that resembled the surrounding desert while H. aureus and R. tibialis generally infested those which had been significantly altered by irrigation and landscaping. H. aureus and, to a lesser degree, R. tibialis, are by far the most economically important of the 18 termite species inhabiting Tucson and the surrounding area. Significant interrelationships were found between termite contract density, customer affluence, housing density, structure age, and soil permeability, and also between retreatment rate, foundation type, and materials used in wall construction. The percentage of structures under contract requiring retreatment was estimated to be between 17.3 percent and 42.7 percent per year. Analysis utilizing termite control contracts is suggested as a unique and effective approach providing critical insight into factors influencing termite communities and patterns of infestation in the urban environment.

Police discretion has been frequently studied in relationship to arrest practices. The present study reconceptualized Shaw and McKay's (1942) social disorganization theory of the causes of delinquency as a theory proposing that police discretion is largely determined by conditions of disorganization. This theory is viewed as more advantageous than conflict theories of police activity because it allows for normative, exchange, and coercive solutions, rather than only the latter as is the case with conflict based theory. To test this theory, individual, structural, and ecological variables were incorporated in the analyses which examined the distribution of type of referral made by the police. Additionally, Black's (1976) proposition that ecological and structural conditions sufficiently explain police behavior was evaluated. Investigation was limited to physical and citation referral. The sample consisted of all referrals of juveniles made during 1984 in Pima County, Arizona. Three regression analyses were performed: (1) individual level characteristics, (2) contextual characteristics only, and, (3) an analysis including both. The results of the first analysis indicated some police bias toward minorities, but the bulk of explanation was attributed to legal variables. The second analysis provided a model that was statistically sufficient to explain police behavior. However, the model indicated that Black's theory requires considerable revision. The last analysis indicated that the bulk of explanation of police behavior was attributable to legal and normative considerations. Few indicators of coercive solutions were located, suggesting that a theory incorporating social disorganization as a determinate of police behavior is superior to a conflict based theory.
