"The study compares determinants of internal and international migration intentions, drawing upon interview data from a sample of adults in Ilocos Norte, a largely rural province in the Philippines. A regression model is applied to test the relative determinants of intentions to migrate to Manila and to Hawaii. The study is based on a value-expectancy model of migration decision making. The results document the importance of subjective expectations related to the attainment of different values and goals in Manila and Hawaii." 相似文献

A statistical estimation of the relationship between socioeconomic factors and net international migration in Western Europe from 1977 to 1980 is presented using data from the Monthly Bulletin of Statistics and the Statistical Yearbooks of the United Nations and each country. It is found that the rate of change in the gross national income, the percentage of the gross national income in the tertiary sector, and the number of automobiles per 1,000 inhabitants are the major factors affecting net migration in the most industrialized countries of Western Europe. 相似文献

The pro-family movement combines religious and political motivations and organizational activities. A major goal of the conservative backlash is to restrict or control alternative lifestyles. Through single issue campaigns and political pressure, the movement attempts to influence legislative and administrative policy. The extent to which the government is an agent of pro-family interest groups is explored here. An important question is whether there is a hidden agenda in the sense that the human services orientation has been exchanged for a control orientation. Do proposals for restoring rights to the family apply only to the traditional patriarchal family? 相似文献

In this paper we show how the algorithm EBLOC can be extended to deal with valued data directly. The technique is then applied to Sampson's (1969) monastery data and comparisons are made with the original EBLOC algorithm. 相似文献

Not with standing human rights linkages, migrants and refugees are often on the periphery of effective international protection. State sovereignty and self-regarding notions of community are used to deny or dilute substantive and procedural guarantees. Recently, even non- discrimination as a fundamental principle has been questioned, as has the system of refugee protection. This article located both migrants and refugees squarely within the human rights context, contrasting both inalienable rights with the demands of sovereignty, and juxtaposing the 2 in a context of existing and developing international standards. Migration and refugee flows will go on, and the developed world, in particular, must address the consequences - legal, humanitarian, socioeconomic, and cultural. Racism and institutional denials of basic rights daily challenge the common interest. This article shows how the law must evolve, responding coherently to contemporary problems, if the structure of rights and freedoms is to be maintained. 相似文献

The Immigration Reform and Control Act (IRCA) of 1986 made 4 types of aliens eligible to receive legalization benefits: 1) those who resided "continuously" in the US since January 1, 1982; 2) those who had worked in the US perishable-crop agriculture for 90 "man-days" in specified time periods (Special Agricultural Workers [SAWS]); 3) those who were in the US since before January 1, 1972; and 4) those classified as Cuban/Haitian entrants and who had been in the US since January 1, 1982. Estimates of the number of aliens eligible for legalization, not including SAWS, ranges from 1.834 million to 2.56 million. Estimates of undercounts of undocumented aliens are 10% for those who entered before 1975 and 37.5% for those who arrived after 1975. Other refinements in the estimates of undocumented aliens include adjustments for 1) ethnic group and location, 2) the growth of the undocumented population between the census date and the legalization eligibility date under IRCA, and 3) emigration and deportation rates. Out of the 1,581,800 applicants entered into the Immigration and Naturalization Service (INS) computers (from a total of 2.15 million applicants) as of May 20, 1988, 73.7% were Mexican nationals. Only 5 other countries contributed more than 1%: El Salvador (6.5%), Haiti (2.3%), Guatemala (2.2%), the Philippines (1%), and Colombia (1%). The Mexican percentage was unexpectedly high, perhaps because the legalization had been much more successful in the Southwest than anywhere else in the country. Reasons that Mexicans have a higher legalization participation rate than other nationalities include 1) the distant eligibility date; 2) ethnic differences among non-Mexican nationalities; 3) particularly in the northeast, fears of exposing one's illegal status to INS; 4) the difficulty of information reaching ethnic communities, 5) the reluctance of those already undergoing the naturalization process to risk the legalization process; and 6) the reluctance of employees to admit employment of undocumented aliens. In the end, more than 90% of applicants are expected to be granted temporary resident alien status (and about 70% of agricultural workers), for a total of more than 2 million people. Researchers estimate that 2.5 - 3 million more persons remain in an undocumented status in the US. 相似文献

The authors develop an econometric model to examine the impact of migration on fertility in Greece in the period 1968-1986. In the model, the fertility equation is considered within a simultaneous equation system, and international migration is included as an explanatory factor of both fertility and per capita income.
