This is an examination of whether city size is truly an independent variable when the relationships between city size and certain economic and social phenomena are considered. A new hypothesis is presented that postulates that relative or systemic city size is an independent variable that affects urban growth patterns through varying, non-optimum migration flows. The hypothesis is tested using official Mexican data for the period 1960 to 1970.  相似文献

The title of this paper comes from an incident that occurred while I was participating in morning rounds on the pediatric and surgical intensive care unit of a large, midwest tertiary care center. The patient under discussion was an eight-week-old girl who had been born without kidneys, and who had been cared for on the unit for seven weeks. In the previous week, the baby's condition had gone steadily downhill, as she experienced on medical catastrophe after another. One of the nurses asked the staff doctor who was leading rounds that morning, "What are the baby's chances?" The physician replied, "Her chances are slim." To which one of the young residents immediately answered, "Slim just left town."  相似文献

A comparison of Japan's and Switzerland's immigration policies disclaims both globalist and public choice explanations that would predict a similar increase in immigrant numbers and an expansion of immigrant rights in liberal democracies. Although both countries have traditionally espoused a rather exclusionary approach towards immigration, Japan is unique in having hitherto succeeded in preempting large numbers of immigrants from entering the country and in having avoided the legal and societal integration of those migrants already present in its territory. In seeking to explain the different trajectories followed by immigration politics in Japan and Switzerland, despite their similar internal and external economic constellations, this article highlights the role of domestic institutions and norms in filtering economic pressure for immigration. Whereas these internal determinants explain to a large degree why Switzerland has become a country of immigration while Japan has not, the central factor explaining the recent expansion of foreign residents’ rights in Switzerland lies not so much in internal determinants but in the country‘s progressing approximation to the European Union and its single market. Notwithstanding these differences, the article concludes that Japan‘s greater resistance to change might now have reached a critical juncture, where demographic pressure and economic demand will make an opening up to increased labor migration unavoidable.  相似文献

There is increasing divergence in the academic outcomes of African American males and females. By most accounts, males are falling behind their female peers educationally as African American females are graduating from high schools at higher rates and are going on to college and graduate school in greater numbers. Some have suggested that school completion and performance is associated with how students feel about themselves. The purpose of this study was to explore gender differences in the relationship between self-perceptions and 2 academic outcomes among a sample of 243 African American high school sophomores. The results suggest that, overall, females are more favorably oriented toward high school completion. Both male and female students with more positive self-perceptions have stronger intentions to complete the current year of high school. Higher grade point averages were more strongly associated with greater self-efficacy for females than for males. Given these findings, increased attention to educational programming, societal messages, and future research is warranted.  相似文献

This article links the literature on the Europeanization of civil society organizations (CSOs) with the literature on the contribution CSOs can make to democracy in the EU. To do so, it asks which are the pull factors that support CSOs’ Europeanization: are they mostly strategic and linked to where law-making and the money are? Or are they likewise linked to a desire to contribute to EU democracy? To explore this question, the article looks at agricultural, environmental and anti-poverty groups and combines fresh qualitative with quantitative data. The findings suggest that we need to distinguish strategic Europeanization, on the one hand, from the identification with supranational democracy, on the other. They also show that the most Europeanized organizations need not be the most interested in EU democracy, whereas organizations with a comparatively low degree of Europeanization can still be interested in EU democracy.  相似文献
