The study reported here was designed to examine the impact of background meteorological conditions on the propagation of noise from urban freeways in the Phoenix area. The aim was to understand and predict how sound waves emanating from highways respond to the vertical profiles of atmospheric temperature gradients and velocity shear, so that sound measurements can be interpreted with regard to the environmental variability.

This report provides a simplified method to be used for evaluating the skin friction and tip resistance of axially loaded drilled shafts. A summary of literature and current practice was completed and then a comprehensive set of field and laboratory tests was performed. Several soil samples were collected from different sites from Arizona and surrounding states. Large scale direct shear apparatus was developed and used to determine the friction between soil and concrete. Finite element analyses were conducted on several prototype cases to determine effect of soil parameters such as dilation on the skin friction values. A step-by-step simplified approach was introduced to determine the skin and tip resistance of drilled shaft foundations in gravelly soils. An example application was presented to guide users in utilizing the simplified approach.

The South Mountains, located on the southern edge of the City of Phoenix, Arizona, have long been considered a sacred place to Native Americans. Numerous trails, many of which are associated with ancient rock art and broken pottery, lead from the base of the mountains into the upper reaches of the canyons. The presence of this rock art and associated artifacts indicates that the trails were created by the Hohokam people, an artistic and intelligent culture. The archaeology and rock art of the South Mountains are currently threatened because of development along the edge of the mountains. Some of the incredible rock art has been documented over the past four decades, but no comprehensive surveys have been undertaken. Consequently, the City of Phoenix collaborated with the School of Human Evolution and Social Change at Arizona State University to undertake a long-term program to survey and record rock art within its cultural and natural contexts.

The primary purpose of this paper is to examine the educational achievement and attainment of Latinos living in Arizona. In short, the educational performance and attainment of Hispanics lags considerably behind that of the state’s non-Hispanic white residents. Moreover, the growth in the number of Hispanics, especially children, has far outpaced that of the non-Hispanic white population, raising the importance of this educational gap. This issue was highlighted in the 2001 Morrison Institute report Five Shoes Waiting to Drop on Arizona’s Future.

The specific goal of this report is to assess the future of Hispanic educational performance and attainment in Arizona, but this outlook is dependent to a very sizable extent on the characteristics of the Hispanics living in Arizona. In particular, the educational achievement and attainment of Hispanic immigrants has been substantially less than that of Hispanics born in the United States. Forecasting Hispanic immigration specifically and the characteristics of the Hispanic population generally is extremely difficult for two reasons: severe data limitations, and recent legal and policy changes related to immigration.

This coloring book was designed at the Phoenix Center for the Arts by a couple of our artists as a tool for students to learn about air pollution and to take preventative actions and become good environmental stewards. It is something fun for children to do while at the same time providing a good story that’s instructive about protecting human health and the environment.

If Arizona is going to be successful not only in improving minority access to higher education, but more importantly, minority student success in higher education, a systematic approach needs to be developed. The answers to improving minority access and achievement in higher education requires a holistic view of education as a system as well as an integrated look into the drivers of academic success. A fundamental problem exists with current policies designed to improve minority representation in higher education. Arizona’s lack of both a systematic view of the problem and the creation of a framework to evaluate policy ideas are sources of these disappointing results. The purpose of this paper is to fill in the gap by providing a framework of focus for academic success to be used to enhance Arizona’s approach to higher education policy.

The information presented here highlights the findings of a drought history study in support of the Governor's Drought Task Force activities, such as determining triggers for drought mitigation and response actions, based on observed hydroclimatic and other information. The material is intended to provide the relevant climatology background for non-specialists, and it is presented in a top ten or frequently asked question format. The questions and answers cover the major climate-related aspects of drought including long-term averages, seasonality, interannual and long-term spatial and temporal drought variations, extremes, and causes of climatic variability. The answers to each question include bulleted Quick Answers followed by a concise explanation of more detailed information. Example figures are presented within the text.
