The objective of this study was to evaluate the effect of typical chemical winter maintenance practices on Arizona Department of Transportation pavements. A review of previous studies on the effect of deicing/anti‐icing chemicals did not yield definitive recommendations, especially for DIAICs typically used by ADOT. Researchers conducted a laboratory study evaluating the effects of magnesium chloride, potassium chloride, sodium chloride, and distilled water on eight different open‐graded rubber‐modified asphalt concrete mixes using the boiling test. All experimental factors were found to be statistically significant, and the researchers provide recommendations on which DIAICs should be used for different binder and aggregate types.

Land Use and Traffic Congestion is an investigation into the links among land use, travel behavior, and traffic congestion. Researchers focused on four transportation corridors in the Phoenix area: three older neighborhoods with relatively mixed, higher density land use, and one suburban area with lower density but high traffic volumes. The analysis suggested that the higher density corridors exhibited less congestion due to the greater mix of uses, shorter trip lengths, more travel by transit and non-motorized modes, and the presence of a secondary street grid system.

Prior to 1967, Arizona had one of the highest infant mortality rates in the country. That year, in an effort to reduce the high infant mortality and morbidity rates, Arizona applied for and received a federal demonstration grant. The grant was designed to reduce infant death by transporting critically ill newborns born in rural hospitals into intensive care centers. As a result, there was a dramatic decrease in neonatal mortality. Part of that grant was to provide home based Community Nursing Services to the infants and their families. Community Health Nurses provided follow-up home visits for the NICP infants and their families up to one year of age.

The Project conducted a State‐level environmental scan to develop a more comprehensive picture of the early childhood‐serving environment in Arizona. An effort was made to identify current funds utilized across multiple State agencies that support programs to address the physical, emotional, social, cognitive, and behavioral health of children from birth to eight years of age. This report describes the landscape of systems, programs and other resources currently available in Arizona that are working to address challenges facing young children, birth to age eight, and their families.

Health Start is a neighborhood outreach program that helps high-risk pregnant women obtain early and consistent prenatal care and, for their children, timely immunizations. Its mission is to educate, support, and advocate for families at risk by promoting optimal use of community based family health and education services through the use of community health workers, who live in, and reflect the ethnic, cultural, and socioeconomic characteristics of the community they serve.

In order to continue to provide crucial sexual violence prevention and education services to its statewide community, the Arizona Department of Health Services, Sexual Violence Prevention and Education Program began comprehensive planning in November 2006, the second year of a five-year funding cycle. The plan was developed as a means of achieving the vision of a culture that supports healthy, respectful relationships through primary prevention efforts and zero tolerance of sexual violence in Arizona communities.

Vision screening of children, unlike hearing screening, is not currently mandated by Arizona state law. The purpose of this document is to provide information, guidance and recommendations for implementing a vision screening program for children ages 3 and older in school and community settings. This document provides guidance and practical information on the screening process, appropriate screening tools, referral criteria and follow-up procedures.

As part of the Long Term Pavement Performance (LTPP) Program, the Arizona Department of Transportation constructed eight Specific Pavement Studies 9 (SPS‐9) test sections on Interstate 10 near Phoenix is an overlay project and is accordingly given independent analysis and documentation in this report separate from Arizona SPS‐9B projects located on US 93, which were new construction and are documented in a separate report. The SPS‐9A project studied the effect of asphalt specification and mix designs on flexible pavements, specifically comparing Superpave binders with commonly used agency binders. Opened to traffic in 1995, the project was monitored at regular intervals until it was rehabilitated in 2005. Surface distress, profile, and deflection data collected throughout the life of the pavement were used to evaluate the performance of various flexible pavement design features, layer configurations, and thickness. This report documents the analyses conducted as well as practical findings and lessons learned that will be of interest to ADOT.

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.
