Under contract HFR-PL-1(31)264, "Concrete Pavement Design and Rehabilitation," a comprehensive data base was created which contains pavement design and construction data, climatic information, traffic data, and condition data for 48 pavement sections. The data base includes projects from jointed concrete pavements (40 sections), prestressed concrete pavements (4 sections), continuousIy reinforced concrete pavements (2 sections), and 3-layer structural rehabilitation pavements (2 sections).

This is a summary of several reports related to government finance in Arizona that have been produced by the Office of the University Economist since December 2008. Some new information has been added in an attempt to provide a complete picture. The format of this report is a brief summary by issue, sometimes accompanied by a table or chart. References are provided to the report and the page number where additional detail can be found.

The purpose of the stabilization fund is to reduce the fluctuations in general fund revenue caused by the economic cycle. These fluctuations result in large budget surpluses in some years and large deficits in other years. Without considering the structural deficit, the budget stabilization fund almost certainly will not have the funding necessary to offset the cyclical reduction in revenue that will occur during the next recession.

For those interested in one of the most extreme state tax and expenditure limitations, TABOR – Colorado’s initiative that limits the funding of most expenditures to annual revenue growth restrained by the sum of annual population growth and inflation rates – would seem to be exactly the right choice. To some, the initiative simply limits government to spend within its means. However, the analysis in this paper reveals that, true to the language in the 1992 Colorado initiative, TABOR limits government growth, and over time the public sector, as a share of the overall economy, declines sharply – crowding out opportunities for investments in strategic initiatives or opportunities for tax reform that may be popular with large voter constituencies or the business community. Advocates point out that provisions in TABOR do allow for voter overrides, but these are costly in both time and money, and until the overrides take place, government is
hamstrung. A simpler, more efficient alternative would be to elect fiscally conservative legislators and hold them accountable for prudent fiscal decisions that strike the right balance between a tax base conductive to economic growth and strategic investments that provide public sector infrastructure, nurturing the business climate and promoting the health and well-being of the citizenry. The paper first outlines the TABOR amendment in Colorado and examines its fiscal consequences for that state. It then examines the potential impact of a TABOR in Arizona.

This study investigated whether highways acted as barriers to gene flow for pronghorn in northern Arizona. DNA samples from 132 pronghorn were analyzed using eight polymorphic microsatellite loci. Samples represented animals living on opposite sides of US Route 89 (US 89) and State Route 64 (SR 64). Two different modeling approaches indicated that both US 89 and SR 64, and to a lesser extent US Route 180 (US 180), acted as barriers to gene flow. The genetic structuring caused by highways, especially across US 89, is consistent with behavioral data that demonstrated pronghorn rarely cross this highway. This study found no evidence of inbreeding or reduced genetic variation in any of the populations examined, but those effects may take longer to appear. Based on these results, the researchers recommend future genetic monitoring of these populations or assessment of genetic variation across highways with larger traffic volumes or longer histories to determine whether the barrier effects documented here lead to loss of genetic diversity.

The condition of Arizona’s infrastructure has a direct impact on economic productivity and quality of life. As economic competition expands domestically and globally, and as the knowledge economy evolves, the importance of a strong infrastructure increases. Education, in particular, is of growing importance. Arizona’s infrastructure challenges will require commitment and creativity to meet the needs and potential of 10 million people and to ensure a positive future for the state.
