Since the second part of the 1980s, and with the negotiation and implementation of the North American Free Trade Agreement (NAFTA), Mexico's growth-and industry-orientated policies have shifted from the realm of public policy to a market-driven domain. This paper suggests that economic openness and the empowerment of market actors is provoking a new regionalisation of Mexico's core economic activities that will play a crucial role in the coming century. For Mexico, the core of NAFTA, so to speak, encompasses a cross-border territoriality covering two key southern American states: Texas and California, and key Mexican states located from the border to the Central plateau of the country. I also argue in this paper that Mexico's changing economic territoriality, triggered by the dominance of the outward-looking economic model, is exacerbating regional inequalities that prevailed in the country even before the outset of economic reforms. This is mainly the case of Mexico's southern region, still very agriculture-orientated, and with a deficit of those export-orientated industries currently fuelling economic growth. This region is the least endowed with mobile assets-such as technology, capital, knowledge-in order to exploit the opportunities of market-orientated policies. Consequently, social cohesion is at stake, not necessarily provoked by the market, but exacerbated by it, and the market mechanism cannot by itself address this problem. 相似文献

Identifying neighborhood thresholds: An empirical exploration 总被引:1,自引:0,他引:1
Abstract In this article, we investigate the threshold‐like effects of four aspects of neighborhood environment: poverty rate, adult nonemployment rate, female headship rate for families with children, and secondary school dropout rate. We used a sample consisting of virtually all census tracts from U.S. metropolitan areas. The relationship between the value of numerous neighborhood indicators in 1980 and subsequent changes in each of the four dimensions of neighborhood quality of family life from 1980 to 1990 was evaluated statistically using a regression model with a spline specification to test for nonlinear, threshold‐like processes. Stressing the exploratory nature of the study, we find evidence of threshold‐like effects in an endodynamic relationship (poverty rate and subsequent changes in that rate), and in exodynamic relationships (occupational status and rental rates and subsequent changes in several neighborhood quality indicators). Implications for research and a spatially targeted neighborhood reinvestment policy are derived from the analysis. 相似文献

The suitability of liquid-liquid extraction (LLE) and solid-phase extraction (SPE) for the preparation of impurity extracts intended for gas chromatographic profiling analyses of amphetamine were evaluated. Both techniques were optimised with respect to the extraction of selected target compounds by use of full factorial designs in which the variables affecting the performance were evaluated. Test samples consisted of amphetamine synthesised by the Leuckart reaction, by reductive amination of benzyl methyl ketone and by the nitrostyrene route. The performance of LLE and SPE were comparable in terms of repeatability and recovery of the target compounds. LLE was considered the better choice for the present harmonised amphetamine profiling method due to the lack of information on the long-term stability of SPE columns. 相似文献

The developments and applications in human biotechnology make us face deep social dilemmas, social and ethical, that are associated to the possibility of altering our evolutionary and cultural development, thereby renouncing to the principle of Humanity. From a sociological perspective, this text reflects on this matters taking into account how its past and present has shaped a specific operational matrix that is projected towards the future. We shall offer all the public perceptions held on their possibilities in Spain and in the European nations as every advance in scientific and technological matters must take into account the opinion of the citizenry. Finally, there are some final reflections that rather than close the debate leave some questions unanswered. The future should be constructed through dialogue and consensus in a matter of such importance. 相似文献

The impact of immigrant labor in the Service sector is best understood by focusing on the organization of production within firms and its effect on employer demand for labor. This analysis of the San Diego restaurant industry identifies a two tier occupational structure, where employers have selectively recruited undocumented immigrants to fill back-house positions. Conversely, the target hiring of the U.S.-born for visible front-house positions completes the cost-effective symmetry which has allowed this industry to flourish. Although the Immigration Reform and Control Act of 1986 (IRCA) threatens this arrangement, its policy effectiveness remains extremely problematic. 相似文献

Although immigrants tend to be less involved in crime than the native-born, less is known about whether immigration is protective regarding family violence and, if so, why. This is especially problematic given that some cultural features of immigrants, such as machismo, may increase family violence. Using a random sample of adults in El Paso County, Texas, the present study finds that family violence is substantially lower among first generation Mexican immigrants compared to 1.5 generation immigrants, second generation Americans and third generation or higher Americans. Higher levels of acculturation to Mexico among first generation immigrants partially mediated, or explained, this finding. However, familism and machismo were not higher among first generation Mexican immigrants; and, while lower among first generation immigrants, acculturation to the US was not associated with higher levels of family violence. Implications of these findings are discussed. 相似文献
