摘要:
SummaryA general form (3) is given of the recursive optimality principle, which is then specialized to the standard case, where a state‐space description is available. The situation with linear dynamics and quadratic costs is briefly reviewed; attention being paid to the certainty equivalence principle, the Kalman recursion, and spectral methods. A couple of trajectory problems are discussed. The qualitative consequences of the stochastic element in these (the “fly‐paper effect”) is mentioned, and an example given of how the stochastic solution is related to the deterministic solution for a certain class of problems. The paper ends with a short section on the statistical characterization of adaptive control.

摘要:
SummaryAnnual morbidity statistics on the prevalence and incidence of mental disorders are not available for the United States or for any other country. However, extensive statistics are available on the patterns of use of state and county mental hospitals and outpatient psychiatric clinics of our nation, and additional statistics are becoming available on patterns of use of psychiatric services in general hospitals.The indexes developed from these data provide measures of the burden of mental disorders on the health facilities of the nation and the extent to which various subgroups of the population use specific types of facilities. Diagnostic distributions of the patient population emphasize the fact that brain syndromes with senile brain disease and cerebral arteriosclerosis, schizophrenia, depressive, alcoholic, personality and transient situational disorders are among the nation's major health problems. These data also document quantitatively the changes that have taken place in the care, treatment and rehabilitation of the mentally ill as a result of many innovations in psychiatric treatment, such as the use of psychotropic drugs, intensive treatment of acute and chronic cases, open hospital, development of additional outpatient clinics and psychiatric services in general hospitals and various intermediary services.Time series on the year and patient populations of the state and county mental hospitals provide another index of change in the care of the mentally ill.The variations in the extent of use of specific types of facilities by the different age and sex groups, and in the diagnostic composition of their respective patient populations, emphasize the major task of co‐ordination and integration of services that face the developing community mental health centres.Some unmet needs for statistical and epidemiological data on the mental disorders are also discussed and some possible solutions to the problems of collecting such data suggested.The planning and realization of the various research and service programmes necessary require a considerable number of well‐trained bio‐statisticians, epidemiologists and social scientists. to provide for such manpower, Government and our academic institutions must intensify efforts to recruit for training in these fields the most promising students from our high schools and colleges. Such action will be essential if the U.S. is to provide the many imaginative and creative scientists required to solve the complex problems that face her.

摘要:
SummaryThe paper asks three main questions. Firstly, if various firms or industries differ in the stress they place on post‐secondary education, is this systematically associated with variations in either their rates of profitability at a moment of time or in their rates of growth over a period? Secondly, whether differences in the level to which trained manpower has been educated appear to be systematically related to improved results, in terms of greater profitability or higher growth. Thirdly, were the observable variations in the stress laid upon personnel trained in various specializations systematically related to growth records or profit performance? The relevant data available are often far from ideal, so that the results are not free from doubt.These questions were first posed in relation to various industries, most of which were in manufacturing. Later, the individual firms in two industries (the iron and steel industry and the construction industry) were compared. Each of these three studies is separate: the available data and the results are quite distinct.

摘要:
SummaryThis paper presents the results of the construction of a working life table for females in Ghana, 1960. Comparisons of the working life table for Ghana with those of other industrialized countries such as the United States of America, England and Wales are made. In addition, some aspects of the uses of working life tables are considered, particularly the examination of annual losses from the actual working population and the factors determining the pattern of losses.It was estimated that out of the total number who left the working population in 1960, 78·2 per cent left because of death and only 21·8 per cent left for reasons other than death. The total loss rate for Ghana in 1960 amounted to 20·5 per thousand female working population; made up of 16·0 per thousand for losses due to death and 4·5 per thousand for losses due to other causes, respectively.The corresponding figures for males in 1960 are 89·9 per cent and 10·1 per cent respectively. The total loss rate for males in 1960 amounted to 23·3 per thousand working population, made up of rates 20·9 per thousand for losses due to death and 2·4 per thousand for losses due to retirement and other causes.
