The first volume begins with the early experiments into wireless telegraphy by Ernest Rutherford and ends with the New Zealand Broadcasting Service in the 1950s, just before the advent of television. Topics dealt with are the development and geographical spread of transmission and reception facilities, the political debates about broadcasting and consequential institutional changes, the interventionist role of the state in broadcasting, programming style and content, and the social and cultural consequences of broadcasting.
Results of the Collaborative Perinatal Project report disclose the risk factors for mental retardation found in children examined from the prenatal period to age seven. Both biological and social risk factors are analyzed for both severe and mild cognitive deficits. The authors of this volume investigated the etiologies of the neurological subgroups of the retarded and reveal, through comparisons with non-retarded groups, important population factors related to normal cognitive development.
