The author applies the 1964 model developed by Stanislaw Czamanski, based on theories of urban growth and industrial localization, to the analysis of urban growth in Mexico. "The advantages of this model in its application as a support instrument in the process of urban planning when the information available is incomplete are...discussed...." Census data for 44 cities in Mexico are used. (SUMMARY IN ENG) 相似文献

The United States Supreme Court’s recent decision relating to violent video games revealed divisions within the scientific community about the potential for negative effects of such games as well as the need for more, higher quality research. Scholars also have debated the potential for violent games to have positive effects such as on visuospatial cognition or math ability. The current study sought to extend previous literature by using well-validated clinical outcome measures for relevant constructs, which have generally been lacking in past research. Cross-section data on aggression, visuospatial cognition, and math achievement were available for a sample of 333 (51.7 % female) mostly Hispanic youth (mean age = 12.76). Prospective 1-year data on aggression and school GPA were available for 143 (46.2 % female) of those youth. Results from both sets of analysis revealed that exposure to violent game had neither short-term nor long-term predictive influences on either positive or negative outcomes. A developmental analysis of the cross-sectional data revealed that results did not differ across age categories of older children, preadolescents or adolescents. Analysis of effect sizes largely ruled out Type II error as a possible explanation for null results. Suggestions for new directions in the field of video game research are proffered. 相似文献

Genotype polymorphism studies at the 13 loci STRs included in the combined DNA index system [CODIS and PCR-based short tandem repeat loci, in: Proceedings of the Second European Symposium on Human Identification, Promega Corporation, Madison, WI, 1998, pp. 73-88; J. Forensic Sci. 46 (2001) 453] (CODIS: D3S1358, HUMvWA31, HUMFGA, D8S1179 D21S11, D18S51, D5S818, D13S317, D7S820, HUMTH01, HUMTPOX, HUMCSF1PO and D16S539) were carried out in a sample of 1429 unrelated Colombian individuals belonging to 25 different departments. As many other countries in Latino-America, Colombia shows an important admixture component, basically integrated by Amerindians, European-descendants and African-descendants. Due to the fact that only partial population analyses have been carried out in the country, the main aim of the present analysis is to establish a database of forensic interest based on the widely used CODIS systems covering the main Colombian regions. 相似文献

Hurricane Mitch caused unprecedented destruction when it swept through Nicaragua and Honduras in October 1998. Official reports estimated that 3,332 were reported killed or missing and an estimated $1.5 billion damages were caused in Nicaragua alone. Though Mitch did not cause Nicaragua's impoverishment, the severity of its destruction revealed a deeper crisis that has been troubling Nicaragua's economy for over a decade—an economic crisis aggravated by heavy external debts and structural adjustment policies. Using feminist analysis, the case of Nicaragua is explored to consider the effects of natural disasters from a global perspective and to rethink the long-term merits of structural adjustment and foreign aid. 相似文献

The benefits of performance monitoring for public services are identified as greater transparency of objectives and accountability for results. This article considers recent experience in developing standards to evaluate efficiency and effectiveness of public services. In broad terms this is being done through performance information which is a much more encompassing concept than standards or indicators. Such information is an element of an accountability framework that provides greater management autonomy and flexibility and extends to the private sector which is increasingly providing, or involved with the provision of, public services. 相似文献

Latin American bureaucracies are notorious for their inefficiency and opacity, yet there is very little empirical research done on what exactly constitutes the “bureaucratic experience” for citizens and what the costs of bureaucratic dysfunction are. To improve our understanding of this topic, 5 cases of Mexican citizens' encounters with public bureaucracies are used to develop the notion of “low‐trust bureaucracy”: public organisations in which access to services is unreliable and the levels of control towards both citizens and bureaucrats are excessive. This bottom‐up analysis of administrative practices contributes to our understanding of the ineffectiveness of government programmes and services, but also of how bureaucracies in developing countries amplify social inequality rather than function as a social equaliser. Furthermore, this article adds new insights to the existing understanding of administrative burdens as a result of either political tactics or mere benign neglect. The data presented here suggest that structural and intractable characteristics of the broader administrative context, such as authoritarian legacies, can produce behavioural patterns that shift bureaucratic attention away from a fair and efficient service provision. 相似文献
