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 Arizona transportation history project was conceived in anticipation of Arizona’s centennial, which will be celebrated in 2012. Following approval of the Arizona Centennial Plan in 2007, the Arizona Department of Transportation recognized that the centennial celebration would present an opportunity to inform Arizonans of the crucial role that transportation has played in the growth and development of the state.

The report consists of a historical narrative and a series of topical essays. The seven-chapter historical narrative is a history of Arizona’s highways that extends from the pre-Columbian era to the present. The 14 topical essays extend the scope of the history beyond the state’s highway system. They include overviews of the development of other transportation modes (railroads, aviation, and urban transit), a brief history of highway pavements, a lighthearted look at the motoring experience during the 1920s and 1930s, and an exploration of how changes in transportation infrastructure affected some Arizona communities. The topical essays also provide additional historical information on bridges, urban freeways, the Interstate system, ADOT and its predecessor agencies, and famous roads such as U.S. Route 66, U.S. Route 89, the Black Canyon Highway, and the Beeline Highway.

The report also includes a timeline of transportation-related developments. This chronology not only provides an accessible overview of Arizona’s transportation history; it also places that history in a larger context by including transportation-related developments from the rest of the nation and around the world. Finally, the report contains a guide to archives in Arizona that hold significant collections of historical photographs related to the state’s transportation history, a bibliography of published historical sources related to the history of highways in Arizona, and a discussion of how the historical narrative and topical essays could be used to produce publications and media that would be made available to the public.

Arizona’s vulnerable populations are struggling on a daily basis but usually do so in silence, undetected by traditional radar and rankings, often unaware themselves of their high risk for being pushed or pulled into full crisis. Ineligible for financial assistance under strict eligibility guidelines, they don’t qualify as poor because vulnerable populations are not yet in full crisis. To be clear, this report is not about the “poor,” at least not in the limited sense of the word. It is about our underemployed wage earners, our single-parent households, our deployed or returning military members, our under-educated and unskilled workforce, our debt-ridden neighbors, our uninsured friends, our family members with no savings for an emergency, much less retirement.

Arizona's recently adopted budget for fiscal year 2015-16 includes dramatic reductions in assistance to low-income families with children. On July 1, Arizona will become the first and only state to limit lifetime eligibility requirements for recipients of Temporary Assistance for Needy Families (TANF) to 12 months (federal law allows for eligibility time limits of 60 months). That means come June 30, 2016, many Arizona families no longer will receive TANF benefits even if they otherwise would be eligible under federal guidelines.

More than one in 10 Arizona public high school students have disabilities. One-third of these youth remain unengaged in work or education following graduation, creating a significant public policy challenge for the state. Why is this so? This report shares findings from 2014 surveys and focus groups conducted with youth and families as well as interviews with education leaders across the state. These responses highlight how Arizona schools and families are preparing these youth, and what the state still needs to do to ensure youth with disabilities have a role to play in Arizona’s job market.

Report takes a look at the pros and cons of three propositions that will be on the November 2014 ballot.
* Prop 122: a constitutional amendment to allow the Legislature to ignore any federal law or action they think is unconstitutional.
* Prop 304: would increase legislator's salaries to $35,000/year.
* Prop 303: would permit a manufacturer to give or sell investigational drugs, biological products, and medical devices to terminally ill patients even though the FDA has not cleared them for general use.

For decades, Arizona was one of the national leaders in aggregate economic growth, as measured by the percent change in measures such as gross product and employment. However, its growth rate always has been highly cyclical. During expansionary periods, Arizona always has been among the top states on the rate of growth. During recessions, the Arizona economy generally slumped at a rate similar to the national average, but would experience a rapid recovery. This pattern continued through the economic expansion of the mid-2000s.
