Adolescents' social behaviors remain a mystery to parks and recreation providers. Adolescence is a "high-risk" time for all youth in terms of experimenting with potentially health-compromising behavior, whether alcohol, drugs, or sex. Most of these antisocial behaviors occur during adolescents' leisure time. These inferences gave impetus to this research effort. The study was designed to ascertain information on adolescents' preferences for pleasure: drugs or recreation. Data were collected from a sample of 100 high school students from a medium-sized college town, and 100 students from a rural town in Florida. Findings revealed four statistically significant associations in the motives or pleasures sought in recreation and in drug behaviors: "enhancement of popularity," "provision of a means for self-discovery," "achievement of personal goal," and means to rebel against parents. In reference to the latter motive, findings revealed that neither drugs nor recreation were used to rebel against parents. Findings also provide documentation of the value of recreation in insulating adolescents against many of the stressors of contemporary life.  相似文献

The objective is to summarize the pattern of Egyptian migration to Arab oil-producing countries (AOPC), to review some factors that are important determinants of labor movement based on theory, and to empirically model the migration rate to AOPC and to Saudi Arabia. Factors are differentiated as to their relative importance. Push factors are the low wages, high inflation rate, and high population density in Egypt; pull factors are higher wages. It is predicted that an increase in income from destination countries has a significant positive impact on the migration rate. An increase in population density stimulates migration. An increase in inflation acts to increase out-migration with a 2-year lag, which accommodates departure preparation. Egypt's experience with labor migration is described for the pre-oil boom, and the post-oil boom. Several estimates of labor migration are given. Government policy toward migration is positive. Theory postulates migration to be determined by differences in the availability of labor, labor rewards between destination and origin, and the cost of migration. In the empirical model, push factors are population density, the current inflation rate, and the ratio of income/capita in AOPC to Egypt. The results indicate that the ratio of income/capita had a strong pull impact and population density had a strong push impact. The inflation rate has a positive impact with a lag estimated at 2 years. Prior to the Camp David Accord, there was a significant decrease in the number of Egyptian migrants due to political tension. The findings support the classical theory of factor mobility. The consequences of migration on the Egyptian economy have been adverse. Future models should disaggregate data because chronic shortages exist in some parts of the labor market. Manpower needs assessment would be helpful for policy makers.  相似文献

Data concerning 624 randomly selected mothers in Ekpoma Region, Nigeria, are used to analyze socioeconomic and cultural determinants of fertility. Factors considered include education, occupation, income, religion, age at first marriage, breast-feeding, and contraceptive practice. The author concludes that the conditions for fertility decline are now in place and that this decline could be accelerated by discouraging early marriage, increasing female education, and promoting contraception.  相似文献

"This article shows that an analysis of the impacts of immigration [in Western Europe] has to be divided into allocational and distributional aspects. From an allocational point of view, like free trade in goods, services and capital, migration is welfare-improving as long as marginal productivities of labor are not equalized worldwide. From a distributional point of view, however, the immigration society has to bear the effects of sharing its common public goods and its social values with the new immigrants. Free immigration will only be allowed if the allocational welfare gains exceed the distributional welfare losses. According to this rule of thumb, a guideline for an efficient migration policy is sketched."  相似文献

Demographic trends in rural areas of the former Soviet Union are analyzed over the 10-year period 1979-1989, using census data. Over the whole country, the rural population decreased by 1 percent, while the urban population increased by 15 percent, although significant differences existed between the European and Central Asian republics. Factors affecting the dynamics of rural populations are analyzed, including the undeveloped social and economic infrastructure in rural areas.  相似文献

The world's population growth rate peaked at slightly over 2%/year in the late 1960s and in 1986 is down to 1.7% and falling. Annual numbers added continue to rise because these rates apply to a very large base, 4.9 billion in 1986. According to UN medium variant projections, world population growth will peak at 89 million/year in the late 1990s and then taper off until world population stabilizes in the late decade of the 21st century at about 10.2 billion. Close to 95% of this growth is occurring in less developed countries (LDCs) of Africa, Asia (minus Japan), and Latin America. LDC fertility rates are declining, except in sub-Saharan Africa and parts of Latin America and South Asia, but most have far to go to reach the replacement level of 2.1 births/woman. Fertility is below replacement in virtually all more developed countries. For LDCs, large numbers will be added before stabilization even after attainment of replacement level fertility because of the demographic momentum built into their large and young population bases. This complicates efforts to bridge gaps between living standards in LDCs and industrialized countries. From a new debate about whether rapid population growth deters or stimulates economic growth, a more integrated view has emerged. This view recognizes the complementary relationship between efforts to slow population growth and other development efforts; e.g., to improve health and education, upgrade women's status, increase productivity. Most effective in the increased contraceptive prevalence and fertility declines seen in many LDCs has been the combination of organized programs to increase access to family planning information and supplies with socioeconomic development that enhances the desire for smaller families.  相似文献

The author analyzes international migration patterns of Caribbean populations, with particular attention to the persistence of significant return flows. A typology of migration in the region is presented, which includes categories of transients or shuttle migrants and settlers or long-stay migrants. Skill or occupational changes, principal remittances, and migration objectives of each group are summarized. The social, economic, and policy implications of international circulation in the Caribbean are considered. (SUMMARY IN FRE AND SPA)  相似文献
