Population experts appear to be reaching a consensus that there has been a perceptible decline over the last decade in the growth of the world's population. The decline is accounted for by the "new demographic transition" in the less developed countries (LDCs). The decline in fertility rates began in the 1950s in some LDCs and became more widespread during the 1970s. The process has not yet begun in many of the LDCs. During the 1960s it was observed that the declines in birth rates (to levels of 30 of less per 1000) were occurring mostly in small countries. Many of these countries were islands with levels of social and economic development above the developing country average. The key question is whether the recent downward trend in fertility in LDCs will continue, stabilize at the current level, or rise again. A primary concern about the future is that the poorer and less developed countries will end up with an increasing share of the world's population, with the share of the developed countries declining from 34% to 22% over the 1950-2000 period. Considerable differential exists in demographic growth patterns among various regions. The 12 largest LDCs (China, India, Indonesia, Brazil, Bangladesh, Pakistan, Nigeria, Mexico, Vietnam, Philippines, Thailand, Turkey) contain 55% of the current world population, and the fertility decline of these nations is expected to have the maximum impact. 7 of these countries have had fertility declines of 14-35%. The force of the "population momentum" must also be considered. Most developing country populations have a young age distribution with considerable potential for population growth even after the fertility level reaches a replacement level and the net reproduction rate equals 1.  相似文献

An employer's capacity successfully to survive a strike will depend largely on the extent to which it has anticipated the strike and taken the steps necessary to defend against it. It is the purpose of this article to catalog the factors employers should consider in approaching an imminent strike and devising contingency plans. It attempts to focus on the types of problems, legal and practical, that frequently arise in strike situations, and suggests certain measures that employers may adopt in preparing for, and defending against, the economic impact of a strike.  相似文献

Mnemic disturbances occurred in 8 of 14 subjects during a pharmcopsychological investigation of possible interactions between alcohol and dipotassium chlorazepate (Tranxilium). The blood alcohol concentrations were between 0.87% and 1.32%; the serum concentrations of the active metabolite nordiazepam were in the therapeutic range between 145 ng/ml and 345 ng/ml. The constitutional, dispositional, and situative conditions are presented. The forensic medical interpretation of such mnemic disturbances must be made critically and with reservation when evaluating a psychopathological state.  相似文献

Changes in the wording of core measures of political attitudes in the American National Election Studies have generated a good deal of controversy about artifactual sources of change in the U.S. electorate. This research, based on several field experiments and replications, investigates the effects of using or not using various types of opinion filter questions that have appeared in the SRC/CPS series over the years. The analysis shows that the use of a filter interacts significantly with a respondent's level of education and interest in politics, particularly the latter, in determining whether a respondent will offer an opinion on a given public policy issue. But the study also demonstrates that such an interaction occurs primarily when the question about interest in politics is askedafter, rather thanbefore, a set of political issue items. In interpreting these order-and-context effects the authors develop a self-perception model of how respondents infer their interest in politics from information that isavailable in memory about their own behavior in the survey interview.  相似文献
