The arguments for and against policy measures designed to increase birth rates in European countries are reviewed. The author concludes that the deterioration of the environment associated with the growth of population in developed countries outweighs any arguments in favor of policy measures to increase fertility. 相似文献

Hammond PJ 《Social Choice and Welfare》1988,5(2-3):127-145
This paper extends the author's recent work on dynamically consistent consequentialist social norms for an unrestricted domain of decision trees with risk to trees in which the population is a variable consequence — i.e., endogenous. Given a form of ethical liberalism and ethical irrelevance of distant ancestors, classical utilitarianism is implied (provided also that a weak continuity condition is met). The repugnant conclusion that having many poor people may be desirable can be avoided by denying that individuals' interests extend to the circumstances of their birth. But it is better avoided by recognizing that potential parents have legitimate interests concerning the sizes of their families.That action is best, which procures the greatest happiness for the greatest numbers. Francis Hutchison (1725).An abiding interest in concepts of optimality for the choice of population has been stimulated by frequent discussions with Partha Dasgupta. This paper was presented at the seminar on Distributive Justice and Inequality at the Wissenschaftskolleg zu Berlin, May 1986. I am grateful to the audience for their helpful comments, especially Maurice Salles and Patrick Suppes, and especially to John Weymark for carefully reading and suggesting distinct improvements to the earlier version. 相似文献

From making to being the excuse: An analysis of deception and verbal/nonverbal issues 总被引:1,自引:0,他引:1
Excuse-making is defined, and the issues of deception and verbal/nonverbal presentations are discussed in regard to the excuse process. Subsequently, the deception and verbal/nonverbal issues are described in greater detail in the context of whether the excuse occurs temporally after a negative outcome (retrospective), before a negative outcome (anticipatory), or as part of the characterological makeup of the person (incorporated). Going from retrospective to anticipatory to incorporated excuses, it is concluded that the role of nonverbal factors increases. Likewise, in the progression from making to being the excuse, it is argued that self- and other-deception also become more pervasive. 相似文献

Dail PW 《International migration (Geneva, Switzerland)》1988,26(4):441-452
The author discusses various social problems resulting from migration to and within the United States, including poverty, acculturation, education, housing, employment, social adjustment, and family difficulties. The potential impact of migrants on the U.S. society and economy is assessed, and government policy responses to their problems are considered. (SUMMARY IN FRE AND SPA) 相似文献

"This article presents estimates of the size of emigration from Poland during the 1980s as well as projections concerning the migration patterns in the 1990s. The author anticipates a contraction of the volume of population outflow by some 50 percent: from about 100,000 to about 50,000 per year, on the average. These projections are based upon the examination of the role of a number of incentives and barriers to migration, including economic, demographic and political factors. In the final section, prospects concerning immigration to Poland are briefly discussed." 相似文献

A comparison of the Korean minorities in China and Japan 总被引:1,自引:0,他引:1
Min PG 《The International migration review》1992,26(1):4-21
"This article compares the Korean minorities in China and Japan in their differential levels of cultural autonomy and ethnic identity....In explaining the differential levels of ethnicity between the two Korean minority groups, this paper focuses on the basic differences in minority policy between the two countries; the difference in the context of migration; the existence or absence of a territorial base; and the differential levels of influence from Korea." 相似文献

Liebig PS 《Journal of aging & social policy》1992,4(1-2):17-33
Shifts in the American political landscape during the 1980s had impacts on aging policy and on the behavior of aging interest groups through that decade. But perhaps even more important are the likely effects of those changes on aging policy and on the roles of age-related groups in the 1990s--and probably beyond. First, some of the major policy trends of the 1980s are sketched out, especially the renewed emphasis on federalism. Then, an assessment of their effects on aging policy and aging interest groups is provided. Next, a rationale for focusing on state-level policy and a discussion of current aging interest-group mobilization at the state level are presented. Last, the prospects for aging interest-group influence in the 1990s--a period in which the prior decade's emphasis on dual federalism is likely to continue--is addressed. 相似文献
