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.

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.

Prior to developing and approving new ordinances that would further regulate sex- offender distance restrictions and clustering, the Phoenix City Council approved a study to examine the nature and impact of sex-offender clustering. Their overall goal was to use the study to fill in some important knowledge gaps about the issue of sex-offender residential clustering in order to inform the development of effective policy. To examine this issue on behalf of the city council, we relied on a multi-methodological research design. We wanted to incorporate information from several different points of view, giving policy makers a more comprehensive perspective from which to inform their decision making. For this study, we relied on four resources: official police data, offender interview data, citizen survey data, and key stakeholder interview data.

The Decision Center for a Desert City at Arizona State University—funded by the National Science Foundation since 2004—conducts research relevant to water resources and urban climate dynamics under multiple uncertainties. This report summarizes and synthesizes research findings and achievements of DCDC after almost a decade of research and science-policy interactions. Water resource decision-making is complicated by climate change and variability, population growth and economic development, diverse stakeholder interests and fragmented governance. While these factors generate various uncertainties and complexities for decision-makers, DCDC pursues research to create a more sustainable future. The DCDC contributes to water management and urban sustainability by conducting basic science and collaborating with policymakers and stakeholders to solve real-world problems. As detailed herein, DCDC research, education, and community outreach have made substantial contributions to improving water-resource governance and climate adaptation.
