Virginia Tech

"Under The Trestle" is the true story of the most compelling murder case in Virginia history. In 1980, beautiful Gina Renee Hall, a Radford University freshman, went to a Virginia Tech nightclub on a Saturday night. She was never seen again. Her abandoned car was found parked beneath a railroad trestle bridging the New River, with blood in the trunk. The investigation led police to a secluded cabin on Claytor Lake, where there was evidence of a violent attack.

The Eleventh International Transport Theory Conference and Symposium in honor of the sixty-fifth birthday of Kenneth Case and the sixtieth birthday of Paul Zweifel was held in Blacksburg, Virginia, during May 22-26, 1989, on the campus of Virginia Polytechnic Institute and State University (Virginia Tech). This volume consists of a selection of the invited papers delivered at the Conference, and represents a cross section of the research currently being carried out in the field of transport theory. The volume is divided into two sections. The Symposium lectures are intended each to summarize an important aspect of transport theory, as well as to present timely new results of the author's research interest. The Conference lectures are contributions of each author on his current research.

The State of Indiana denies one million applications for healthcare, foodstamps, and cash benefits in three years because a new computer system interprets any mistake as "failure to cooperate." In Los Angeles, an algorithm calculates the comparative vulnerability of tens of thousands of homeless people in order to prioritize them for an inadequate pool of housing resources. In Pittsburgh, a child welfare agency uses a statistical model to try to predict which children might be future victims of abuse or neglect.
