The author examines the relationship between highway improvement and changes in urban form in the St. Louis Standard Metropolitan Statistical Area (SMSA). The paper briefly reviews the literature concerning industrial location, and then summarizes highway improvements and land use changes that occurred in the St. Louis region during the 1960s. The paper presents regression models relating land use changes to travel time change and reports the results.

Documents an attempt to develop an objective measure for peacetime evaluation of a fighter pilot's air-to-air combat skills. Previous research and combat data from Korea and North Vietnam suggest that the skill of the individual pilot is crucial in the outcome of an aerial engagement. However, it has not been possible to estimate the actual effect or to identify what makes him superior. The Air Force cannot currently evaluate its pilots' air-to-air skills objectively during either their training or operational assignments. This report proposes four research areas that address the effectiveness and evaluation of these pilots: the selection of the prospective pilot from his undergraduate pilot training program, the air-to-air portions of his combat crew training squadron curriculum, the more efficient management of pilot resources, and an examination of the costs and benefits of dissimilar air combat training. It also proposes the development of a pilot skill index.

"This report reviews recent developments and trends in international terrorism that could affect the safety and security of U.S. nuclear weapons research sites and production facilities. It is based on an examination of prior research findings and new evidence concerning the terrorist threat to U.S. nuclear weapons facilities. The findings suggest that the motivation, characteristics, and capabilities of potential adversaries have changed little in the past decade. However, two developments--a dramatic increase in state sponsorship of terrorism (i.e., sponsorship of terrorist groups by foreign governments) and a shift in emphasis within both the American and European anti-nuclear protest movements from energy to weapons--may necessitate some revisions in nuclear facility defense requirements."--Rand Abstracts.
