An Historical Analysis Of Public Policy For The Care And Treatment Of People Who Are Mentally Retarded In Michigan, Kenneth O. Slater

Dissertations

This dissertation traces the historical development of Michigan's public policy associated with the residential care and treatment of mentally retarded people. Michigan laws and programs from 1830 through 1983 were studied after being compared to a national history. The central question was: What factors, over time, influenced public policy related to residential care and treatment of the mentally retarded?

Initially, care was the responsibility of families and friends of the mentally retarded. This responsibility shifted from townships to counties, then to the state during the nineteenth century. Until the late 1800s many mentally retarded people were housed on county poor …

Comparison Of Electron And Light Microscopy Of Chromosome Aberration Induced In Human Lymphocytes By Adriamycin And Mitomycin C, Abbas Parsian

Dissertations
