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.

In the fall of 1995, the City of Phoenix Police Department convened a special group of people known to be deeply involved with the social and personal aspects of domestic violence. This group, which came to be called the Phoenix Police Department's Joint Task Force on Domestic Violence, consisted of police and criminal justice personnel, social service and health care providers, and a number of interested community members. Task Force members soon began earnest discussions on how best to reduce the incidence of domestic violence-a crime that is, sadly, the number one call for police service in the City of Phoenix.

Tourism is one of 12 industry clusters widely considered to be driving the Arizona economy according to the Governor’s Strategic Partnership for Economic Development (GSPED). The term "cluster" refers to a geographic concentration of interdependent companies, suppliers, products, labor pool, and institutions that together constitute an important competitive advantage for a region. In northern Arizona, tourism ranks as the predominant industry cluster. This paper provides a profile of the tourism cluster in Coconino County, with special focus on the Flagstaff area. It examines the cluster’s composition, relative size and importance to the regional economy. It addresses the cluster’s dynamics and requirements for growth. It reviews important national and worldwide trends affecting tourism in Arizona, as well as the special characteristics of gateway communities. And, finally, it presents a menu of actions to choose from for strengthening the cluster in both Flagstaff and Coconino County.
