Is the authoritarian potential of policy elites a mortal threat to the consolidation of democracy in Latin America? This article suggests that in the context of democratic transitions, significant variations may exist in the performance of technocratic roles. In most countries in the region, elected governments faced the crisis of the 1980s by retaining markedly technocratic and exclusionary styles of policy-making. In Chile, a highly technocratic form of authoritarianism was succeeded by a novel pattern of pragmatic cooperation between technical and political elites. Democratic institutions were reestablished while a strong economic team enforced coherence and continuity in economic policy. Historical and institutional factors are used to show that Chile may now be nearer the democratic pole than other “hybrid” democratic-authoritarian regimes in the region. 相似文献

A fast and sensitive method for the determination of carboxyhemoglobin (COHb) in blood using derivative spectroscopy is described. The addition of sodium dithionite as a reducing agent is not required. The concentration interval studied was from 0.5% to 100% COHb. 相似文献

We suggest the use of the mismatch distribution methodology as an easy way to estimate the distance between all pairs of haplotypes present in a sample. This approach allows the evaluation of the proportion of pairs of Y-STR haplotypes that are prone to become identical by state (IBS), in one generation, by recurrent mutation, a statistic of major importance in the forensic field. The mismatch approach presents some advantages alternatively to the empirical one, since it is not necessary to have simultaneous information on STRs and SNPs, and it allows the evaluation of IBS also within-haplogroups. The estimation of IBS at an European scale showed that there is a high population substructuring for this parameter, increasing from southern-central European countries towards west and north, in accordance to what was found for Y-biallelic markers. This result seems to imply a more careful use of large databases for matching evaluation, even in the absence of population structure for general Y-STR diversity. Furthermore, mismatch distribution can be used to measure the distance between a particular haplotype and all the haplotypes in a sample. When applied to the most frequent haplotypes in Europe it revealed that the opportunity for IBS is not directly related to the frequency of a haplotype, but highly dependent on the proportion of neighbouring haplotypes--so, that reporting on the haplotype frequency for evaluating the significance of a match can be misleading. 相似文献

Pros and cons in the use of SNPs in forensic kinship investigation: a comparative analysis with STRs 总被引:4,自引:0,他引:4
Recent advances in single nucleotide polymorphisms (SNPs) research have raised the possibility that these markers could replace the forensically established short tandem repeats (STRs). In this work, we compare STRs and SNPs applicability for kinship investigation in terms of expected informative content and probability of occurrence of "difficult cases" (when isolated Mendelian incompatibilities between alleged father and child are found). Since SNPs have a much lower mutation rate than STRs, these difficulties were expected to occur less frequently if SNPs were used instead of STRs. The purpose of this paper is to make some simulations allowing the estimation of how often such difficult cases are expected to occur using both types of markers and how serious can be their impact in routine work. Our results demonstrate that a battery based exclusively on SNPs matching the informative power of current STR kits would be prone, if applied to routine paternity investigation, to the occurrence of cases where the statistical evidence would be inconclusive. We infer that the introduction of a SNP based strategy, as a substitute to the now classical STR approach poses statistical problems that must be carefully evaluated. 相似文献

We present allele frequencies and forensic parameters for 17 STRs included in the AmpFlSTR Identifiler (CSF1PO, D2S1338, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D19S433, D21S11, FGA, TH01, TPO and VWA) and Powerplex 16 System (CSF1PO, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, FGA, Penta D, Penta E, TH01, TPO and VWA) in a sample of 134 unrelated individuals from Equatorial Guinea located in Western Africa, between Cameroon and Gabon. Hardy-Weinberg equilibrium was tested for each locus and the sample was compared with five African databases: Promega's and AB Applied Biosystems African-Americans and samples from Mozambique, from Cabinda (Angola) and Guinea-Bissau. 相似文献

This work studies the issue of political representation from the perspective of a specific legal culture, the exercise of political rights in the context of the occidental democratic system, a concept that has undergone a profound evolution to the present day. The essential aspects for an analysis of this progression are voting, decision making, and the relationship between representatives and their constituents. Overall, the phenomena making up the crisis of representation have been explained as a result of changes that have affected the operation and structure of modern states constituted as representative democracies. The idea is that a well-functioning representative system comes primarily from the form of government and electoral system in which it develops. 相似文献
