The evidence on enduring effects of education is provided by 151 discrete questions from American national surveys conducted between 1949 and 1975, which implicated various values in diverse situations. Since the influence of education on each item is examined separately for each of four age cohorts, our detailed findings involve 600 sets of comparisons of(More)
In many object recognition problems, the object to be identiied is one of a xed set (library) of objects. The problem of identifying which object is present then shares characteristics of the signal detection and parameter estimation problem: which signal is present and what are its parameters? The Reciprocal Basis Set/Direction of Arrival (RBS/DOA)(More)
Certain sociological problems are less likely than others to be studied through primary field research. Some deal with topics that do not seem important enough to warrant the expense of a full-scale field inquiry; others treat subjects about which most people believe the facts are known; some involve events and opinions in the past which cannot be measured(More)
Phosphorus losses from agricultural land can cause accelerated eutrophication of surface water bodies. This study evaluated the use of soil test phosphorus (STP) levels to predict dissolved inorganic phosphorus (DIP) concentrations in runoff water from agricultural soils using laboratory rainfall simulation. The objectives of this study were to determine(More)
The study of mass communications is a broad, multidisciplinary field to which sociology has made major contributions. Some of these contributions have been reviewed in earlier works by Riley & Riley (1959), Larsen (1964), Janowitz (1968), McQuail (1969), Davison & Yu (1974), & Ball-Rokeach (1975), and Wright (1975a). Several chapters in Annual Review of(More)

The incidence of beta-thalassaemia trait among Cypriots in London is about 14%, and the birth rate of children with thalassaemia major is 0.6%. The high incidence of the beta-thalassaemia gene among Cypriots suggests the desirability of screening Cypriot school-leavers for thalassaemia trait and following up any incidentally discovered cases with family(More)
