abstract: The Maricopa produce one of the most recognizable types of pottery made in Arizona. Since the late nineteenth century, the ware has been manufactured for sale, and a small number of individuals continue to produce the pottery today. Over the past forty years, the amount of pottery in museum and private collections has increased dramatically. Studying these new collections changes the way in which developments in the pottery are understood. Previous scholarship identified three phases of development, including a pottery revival in the late 1930s during which the involvement of government and museum personnel resulted in the improvement of the ware and a change in style. An analysis of expanded pottery collections shows that this period was not a revival, but rather part of a more gradual continuum. Hindsight shows that the activities of the 1930s served to publicize Maricopa potters, resulting in an increasingly collectible pottery. One collector, Adele Cheatham of Laveen, Arizona, compiled a collection that helps to shed light on developments in the 1960s and 1970s demonstrating that there were relationships between the potters' community and residents of Laveen. This indicates that for women in these settlements the manufacture and sale of Maricopa pottery was a common interest and created deeper bonds, some of which developed into close friendships. The eight different potters represented in the Cheatham Collection highlight a shift in generations within the potter community, showing the importance of teaching and family relationships in transmitting the knowledge of the craft to the next generation. These relationships have continued to change as the number of potters has dwindled, and instruction of the craft has transitioned from one that was learned in a home setting to one that is increasingly introduced in a classroom. At the same time, this historically female associated craft has shifted to one where men are actively producing pottery. Changes in teaching style, the people producing the pottery and decorative techniques indicate that Maricopa pottery is an art in transition. / Dissertation/Thesis / M.A. History 2010

The effect of hydrogen cyanamide (H₂CN₂) on budbreak and fruit maturity of 2-year old 'Flame Seedless' table grapes was investigated in a low desert climate in central Arizona. Dormant sprays of H₂CN₂ applied at 2.5 and 5.0% (v/v) concentrations hastened budbreak by at least 16 days with subsequent advancement of fruit maturity by 5 to 10 days. A 5.0% (v/v) dormant application of H₂CN₂ to whole vine, buds only or pruning cuts only advanced budbreak by at least 16 days and advanced fruit maturity by 1 to 5 days, regardless of application site. A more uniform budbreak was observed on H₂CN₂ treated vines, regardless of concentration or site of application when compared to control vines.

A modified plate load (MPL) test was developed to measure the in situ cohesion of a carbonate or caliche cemented soil. The MPL test was performed on the crest of a vertical cut in alluvial soil with a steel plate loaded until the soil failed. A three-dimensional slope stability analysis was then used to back calculate soil cohesion. In situ test results were used in conjunction with laboratory testing of deaggregated soils samples to completely define the Mohr-Coulomb strength parameters of the in situ soil. In order to check the result of the in situ test procedure, the field test conditions were modeled for use in a two-dimensional slope stability analysis using the computer program CSLIP1. A comparison of the results shows reasonable values of soil cohesion were obtained using the MPL test method.

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. / Chlamydia and gonorrhea are among the most frequently reported infectious diseases in the United States. These two diseases are easily treated with antibiotics; however, challenges exist in providing treatment to cases and their sexual partners. Maricopa County implemented a Field Delivered Therapy (FDT) protocol to treat chlamydia and gonorrhea cases and contacts in 2009. Ultimately, this project sought to inform other public health departments across the United States regarding the benefits of FDT program to treat gonorrhea and chlamydia and provide better insight on how to treat the two most commonly reported infectious diseases. Existing data was analyzed from April 1, 2011 to October 31, 2014 (42 months) for all patients that received FDT in Maricopa County utilizing pharmacy records and electronic health records (PRISM and eClinicalWorks). The following pieces of information were collected from these data sources: gender, age, race/ethnicity, diagnosis, number of partners, and time to treatment. The data were then divided into four FDT groups (FDT, expedited partner therapy via FDT, FDT attempted and FDT planned). There were 172 patients in this analysis; 140 diagnosed or in contact with chlamydia and 16 diagnosed or in contact with gonorrhea. There were 79 patients (45.9%) in the FDT group, 28 (16.3%) in the FDT EPT group, 28 (16.3%) in the FDT attempted and 37 (21.5%) in the FDT planned group. The median age of these patients was 23.8 (range 16.6‐31); 111 (64.5%) were female. The median time to treatment for these patients was 24.6 days (range 0‐64.5 days). Most patients (79.6%) lived outside of central Phoenix. The median number of sexual partners reported by these patients was 6.6 (range 1‐19.7 partners). A majority of the patients were <25 years old, except for in the FDT EPT group where 100% of patients were >25 years old. And the group with the largest <19‐year‐old population (32%) was in the FDT group. All the groups had a female majority, except in the FDT EPT group where 75% of the patients were male. Most patients in the FDT only group received testing at an outside hospital or outpatient clinic, while the FDT attempted and planned were more often tested at the STD clinic. Future Direction/Conclusion Many of the patients that received FDT are young women, some pregnant, that lived outside of Central Phoenix. However, a majority of the overall clients that received expedited partner therapy via FDT were male, a typically hard to reach population for treatment of potentially asymptomatic infections. This study demonstrates an effective method of delivering partner treatment to men. This study can be used to inform other public health departments about this novel practice and to help Maricopa County grow their FDT program to reach even more untreated patients.

Introduction: Vector-borne infectious diseases represent a major public health problem in both developing and developed nations. In particular, West Nile Virus (WNV), a mosquito-borne disease that can lead to severe disease and death in humans, caused over 2,100 reported cases in the United States last year (CDC, 2016). In Maricopa County, Arizona WNV has caused 474 reported cases during the last five years, with a case-fatality rate at 7.8%. Aim: To examine the association between weather patterns and incidence of WNV in Maricopa County, AZ from 2007 to 2013. Methods: We analyzed weekly data on climatological variables and WNV incidence from Maricopa County, AZ. The specific independent variables of interest were precipitation, minimum temperatures, mean temperatures, and maximum temperatures. A full model was generated using multiple linear regression, and a stepwise selection procedure yielded a minimal model. Results: The full multiple linear regression model explains 45.30% of the observed variance in WNV incidence. The variable showing a significant impact on WNV incidence in this model was rainfall (p <0.0001). Stepwise selection results explained 45.16% of the variance observed in the data. This model included two significant predictors: precipitation and maximum temperature. Conclusion: Climatic variables, particularly the amount of rainfall and maximum temperatures, significantly influence WNV dynamics in Maricopa County, Arizona. These findings are in line with prior studies and could be useful to guide mosquito control programs in the state of Arizona.
