This paper attempts to measure infant and child mortality levels and also to determine their structure by utilizing the results of the 1968–1969 National Demographic Sample Survey which was conducted under the directorship of the author. Among the major problems encountered in the exercise are the adjustment of the current raw mortality data and the estimation of infant and child mortality from independent source material. The estimated infant mortality rates range from 56 per 1,000 live births in the Accra Capital District to 192 in the Upper Region during the late 1960’s. The urban rate is lower than the rural rate, 98 as against 161 per 1,000 live births. A large proportion of the deaths among children aged 0–4 occur in the second year of life, and deaths in this age group account for the bulk of the deaths within the age group 1–4 years.  相似文献

Conclusion The nursery school may be considered an institution and a market where the habits produced by the family are moulded, developed and standardized; thus, it is confronted with an objective definition of early childhood embedded in pedagogical practices. The proper objective of a sociology of nursery-school practice is the analysis of the lag between the functions delegated to the school by the different social classes and the functions which it objectively tends to fulfill. Here we have the best test of the lag between the pedagogic demands of the different classes and what the schools supply-which is very abstract, with results that are only visible at a later stage in the school career. It is not so much a question of learning to read or of preparing to do so (the acquisition of certain logical operations or a developed sensitivity, of acquiring a few I.Q. points). This learning takes place through many varied activities which apppear to be far from the learning function.All told, the conditions for understanding nursery-school exercises flow from the conditions for inventing these exercises. For instance, in games of manipulation, construction, classifying various objects, is not some knowledge of Piaget (at least in the sense of some psychologikal knowledge) needed to understand that practical manipulation is also logical manipulation, to see in cube games the learning of logic? Similarly, the language naïveté cultivated in language games is a clever naïveté, which supposes for example a cultured re-discovery of popular archaic language or of child talk. p ]Is it not likely to appear as pure childishness to those who, without the ncessary cultural knowledge, do not have the keys to decipher these ostensibly naïve exercises? Similarly, the conditions for understanding children's drawings as artistic learning (and the nursery school as an educational institution) are the very conditions for understanding modern art as art.It is not just a matter of perception and understanding; as the objective definition of early childhood proper to the different social classes becomes pervasive both in the relationship with school and in the socialization practices of the family, it patterns the children's habitus (as long-lasting internalized dispositions), which in turn influence the child's behavior and attitude towards school.The perception categories and the different forms of treatment of young children appropriate to each social class are not simply the result of the diffusion of definitions of early childhood produced by the autonomous evolution of scientific and artistic disciplines. They are the products of all the social and cultural conditions which define the class situation. We may also wonder whether at least some pedagogy and certain types of exercises do not presume that the child has socially marked attitudes, produced in some classes by family inculcation. For instance, a general attitude of disinterested interest is required by a pedagogy offering multiple activities and open to an attitude of active research and exploration. Does not this attitude suppose as an existential possibility the condition of social classes protected from economic pressure and from the urgency of immediate life, a general attitude towards life nearer to leisure than to the constraints of work?Thus, in confronting supply with demand—here even less than elsewhere-there is no question of comparing the expectations arising from users' opinions with the program offered in the official definition of the institution. The expectations are those which arise from objective determinations inherent in each social group, the forms of treatment and perception of early childhood. To analyze the program-and therefore to ascertain the social conditions governing the use of the nursery school—the dominant definition of early childhood on which the institution is founded must be brought to light. Moreover, the way in which this definition is written into the curriculum (and, subsequently, into pedagogical practice) must also be studied. This implies that the preliminary condition for a sociological analysis of the functions performed by the nursery school for the different social classes would be an analysis of a) the components of this dominant definition of early childhood and b) of the social conditions in those groups which make it possible to identify these components.We wish to thank P. Bourdieu for his advice during our research. R. Collins provided useful suggestions after reading the first version of this paper.  相似文献

Summary In Matlab Bazaar Thana the Cholera Research Laboratory has registered the births, deaths and migrations in a population of approximately 125,000 since 1966. Although this rural area was not the scene of any significant armed encounters, striking changes in birth and death rates were registered during and after the conflict. Birth rates did not change during the relatively brief period of the civil war, but a small decline was registered for one year after the war. Fertility rates which had been declining slightly and irregularly in the pre-war baseline period may have increased slightly during the war and fell substantially in all age groups in the year following the war. The crude death rate, which rose by 37 per cent during the war, was a very sensitive reflection of the administrative and economic problems. Overall infant mortality rose by only 15 per cent over pre-war levels because all of the increase was observed in the post-neo-natal component, which traditionally accounts for less than one-third of the total infant mortality in Bangladesh. Children and older adults accounted for the majority of excess deaths which were largely attributed to acute diarrhoeas and other gastro-intestinal causes. The death rate at ages 1-4 rose by 43 per cent and at ages 5-9 soared to 208 per cent above pre-war baseline rates. All increases in age-specific mortality rates fell to baseline levels during the year following the war, except the 5-9-year age group, in which rates continued to be high largely because of deaths due to dysentery.  相似文献

In the production planning and control of discrete-parts manufacture, aggregation of parts into families, on the basis of similarity, is carried out to ease both long-horizon planning and short-horizon scheduling. Additional advantages are related to those of group technology (GT), such as simplifying the flow of parts and tools and reducing both set-up and production costs. The problem of formally forming part families is presented and discussed. Previous work is reviewed and assessed. Two solution approaches, one based on a location model, the other on simulated annealing, are presented and compared along with test results. The location formulation, which results in an integer programming model solved by Lagrangian relaxation, proved capable of producing solutions of excellent quality, but only for relatively small problem instances. In contrast, simulated annealing, which is a general heuristic approach to combinatorial optimization, produced solutions of comparable quality and could handle realistically large problem instances. However, careful design of the simulated annealing algorithm is crucially important. An effective design is presented.  相似文献

In recent years there has been a good deal of discussion amongst planning specialists and academics about the gap which exists between the theory of planning as set out in journals and textbooks, and the practice of planning in private and public organizations. Planners are continually complaining about the resistance to planning by top management and operating managers in divisions and departments.In this article the author aims to produce a reconciliation between theory and practice and to discuss what alternative strategies are open to planners in devising planning systems for their organizations.He suggests that the problem has its origin in the fact that corporate planning theory was first developed by management scientists as a total systems approach. Corporate planners have failed to sell an integrated planning system either as programme budgeting or as corporate planning. Research suggests that a management team can only adopt and implement a comprehensive planning system in very special circumstances, e.g. when the organization's survival is threatened, a new management team has been appointed and the staff of the organization are ready to accept radical change.In normal circumstances the planner is wrong to advocate a ‘root and branch’ solution. He must diagnose the planning needs of the organization and his objective must be not merely to establish a particular planning procedure but rather to discover how he can best improve the quality of management decisions.Recent studies on strategy formation indicate that the introduction of a formal planning procedure is only a partial answer to the problem of improving the quality of management decisions.The paper reviews various approaches to planning and considers how they relate to organizations with different strategic problems, with differing organization structures and various management styles.  相似文献

Using the first (1995) and third (2001-2002) waves of the Add Health survey, we examine women 's family transitions up to age 24. Only a third of all women marry, and a fifth of those marriages dissolve before age 24. Three out of eight women have afirst birth, with a substantial majority of those births outside of marriage: 66% for whites, 96% for blacks, and 72% for Mexican Americans. Cohabitation is the predominant union form; 59% of women cohabit at least once by age 24. Most cohabitations are short lived, with approximately one in five resulting in a marriage. We summarize the family and relationship experience of women up to age 24 in terms offour categories, each accounting for roughly a quarter of all women. Category 1 has the women who remain single nonparents. Category 2 has the early marriers, women whose marriage is not preceded by a first birth. Category 3 has those who become single parents. Category 4 has the women who cohabit at least once, but who do not marry or have a birth by age 24. The strictly ordered transitions of the 1950s are long gone and have been replaced by a variety of paths to adulthood.  相似文献
