"The paper argues that women's status in Haiti is a factor favorable to the spread of modern contraception and a potential rapid demographic transition from high to low fertility. After briefly reviewing recent theories on the determining of fertility declines, the paper considers women's status in Haiti. It discusses family patterns, conjugal unions, and economic activities. Finally, it reviews current patterns of contraceptive use and considers how these are related to various aspects of women's status."  相似文献

These three papers on the future of migration make up a summary report on the Conference of National Experts held at the OECD in Paris, May 13-15, 1986. The papers concern possible policy options, international migration as a basic element of economic development, and conclusions about migration trends from the present to the long-term future. The author of the concluding paper remarks that "the Conference brought representatives of all of the Organization's Member countries together with eminent economists and social scientists to discuss the possible and probable outlook for migratory movements in the years to come. The purpose was not to define international norms in this respect, nor to draft one or more international agreements or a legal instrument having the force of law, but to review all the problems raised by that outlook."  相似文献

"This paper examines the assimilation of immigrants in familial and economic fields.... Specific objectives are as follows: (1) to describe fertility and earning patterns among immigrants to the United States in 1970-1980, from several countries of origin, and (2) to describe some effects of assimilation, human capital, and the dual labor market perspectives on immigrant earnings." Findings vary in both fertility and economic categories for migrants depending on whether they are from developed or developing countries. (SUMMARY IN FRE AND SPA)  相似文献

Ostensibly, the approval of legalized casino type gambling in the Netherlands was intended to combat illegal and uncontrolled gambling. Very early on, however, the plan conceived and implemented by the Netherlands Parliament demonstrated serious mismarketing strategies and tactics. The new legal casinos were appealing to people other than those engaged in illegal gambling, in particular foreign tourists and local high rollers. This paper attempts to analyze the ultimate process of goal displacement, as the state casino industry allowed economic objectives to supplant desires to utilize legal casinos primarily as controls over illegal gambling.  相似文献

"This article investigates the application of the three-parameter, Coale-McNeil marriage model and some related hyperparameterized specifications to data on the first marriage patterns of American women. Because the model is parametric, it can be used to estimate the parameters of the marriage process for cohorts that have yet to complete their first marriage experience. Empirical evidence from three surveys is reported on the ability of the model to replicate and project observed marriage behavior. The results indicate that the model can be a useful tool for analyzing cohort marriage data and that recent cohorts are showing relatively strong proclivities to both delay and forego marriage. Consistent with earlier work, the results also indicate that education is a powerful covariate of the timing of first marriage and that race is a powerful covariate of its incidence." Data are from the U.S. Current Population Survey for 1976 and 1985 and Cycle III of the National Survey of Family Growth for 1982.  相似文献

Research suggests that hurricane‐related risk perception is a critical predictor of behavioral response, such as evacuation. Less is known, however, about the precursors of these subjective risk judgments, especially when time has elapsed from a focal event. Drawing broadly from the risk communication, social psychology, and natural hazards literature, and specifically from concepts adapted from the risk information seeking and processing model and the protective action decision model, we examine how individuals’ distant recollections, including attribution of responsibility for the effects of a storm, attitude toward relevant information, and past hurricane experience, relate to risk judgment for a future, similar event. The present study reports on a survey involving U.S. residents in Connecticut, New Jersey, and New York (n = 619) impacted by Hurricane Sandy. While some results confirm past findings, such as that hurricane experience increases risk judgment, others suggest additional complexity, such as how various types of experience (e.g., having evacuated vs. having experienced losses) may heighten or attenuate individual‐level judgments of responsibility. We suggest avenues for future research, as well as implications for federal agencies involved in severe weather/natural hazard forecasting and communication with public audiences.  相似文献
