Nine industrial-location research studies of the Appalachian region are presented in this document. These studies relate to the casting, plastic, metal, and food industries. Each study devotes sections to (1) a profile of the industry, (2) the industry's prospects for growth, (3) technology and trends, (4) primary factors influencing selection of locations, and (5) selecting public-investment policies and activities which will enhance the competitive position of Appalachia. It is noted that, although some industry relies heavily on in-plant training through the apprenticeship programs, the area of vocational training is felt to be one of the most effective public investments for industry. Suggested course offerings for vocational education are given for some of the industries. Each study is appended with pertinent information. (Related documents are RC 004 206 and RC 004 211.) (AN)
