This paper is concerned with the reciprocal relationship between migration and development in Third World settings. Using individual-level data for Venezuela, migration behavior is related to a person's age, educational attainment, gender, and characteristics of his/her place(s) of residence as an out-migrant, in-migrant, or stayer. Place characteristics are in terms of four groups based on employment patterns: the core, regional centers, resource frontiers, and traditional rural areas. Four questions are of concern. First, does development influence migration? All analyses indicate this is so. Second, does migration influence development? Findings are ambiguous in that places experiencing improvement in their mix of human capital lagged in the net number of persons obtained through migration whereas a gain in numbers was accompanied by deterioriation in human capital profiles. Third, was incipient polarization reversal occurring in Venezuela in the late 1960s, early 1970s? This paper departs from the usual approach by addressing this question in terms of human capital attributes instead of population aggregates. On this basis, polarization reversal is in evidence, particularly in regional centers. Finally, this study answers in the affirmative that places with different development characteristics generate migration streams differing in type, magnitude, explanation, and impact.  相似文献

This article focuses on the particular moment of the 1945 United Nations charter meeting as a catalyst for a shift in Mary McLeod Bethune's feminist thought. The meeting, where Bethune served as the only African American female delegate, signalled a change in Bethune's thinking about equality for black women, so she used the founding of the United Nations as a platform to promote black women's alliances with other women of colour. Her idea was to reframe black women as citizens of the world, thus putting them in a numerical and ideological majority rather than keeping them in a minority position. Bethune has often been viewed as a reformer of race and gender issues in the early twentieth century, but a focus on her activism has hidden the intellectual contributions that she made to a form of black feminism that emerged out of her work with other clubwomen and through the United Nations in the 1920s through the 1950s. Specifically, this article argues that Bethune's intellectual work created a framework for African American women's feminism that emphasised anti-colonialism and their global alliance with other women of colour throughout the world.  相似文献

The need for experiments to study physical aspects of craft of the past is stated, as well as the necessity for them to have clear aims and to follow the established principles of scientific enquiry. These principles are discussed in this joint paper by ten maritime archaeologists and others, together with methods and some points of management critical to their application in this field.  相似文献
