Allele frequencies, together with some parameters of forensic interest were estimated for nine STRs included in the AmpF/STR Profiler kit (CSF1PO, D3S1358, D5S818, D7S820, D13S317, FGA, TH01, TPOX and vWA) in a sample of 215 unrelated individuals from Cartagena (Colombia). For all loci, no significant deviations from Hardy-Weinberg equilibrium were observed. Comparative analysis results between our data and those from other Colombian and African population samples revealed significant differences, except with two Colombian Caribbean Coast sub-regions. 相似文献

An analytical method using solid-phase extraction (SPE) and high-performance liquid chromatography–mass spectrometry (LC–MS) has been developed and validated for the confirmation of Δ9-tetrahydrocannabinol (THC) in oral fluid samples. Oral fluid was extracted using Bond Elut LRC-Certify solid-phase extraction columns (10 cm3, 300 mg) and elution performed with n-hexane/ethyl acetate. Quantitation made use of the selected ion-recording mode (SIR) using the most abundant characteristic ion [THC + H+], m/z 315.31 and the fragment ion, m/z 193.13 for confirmation, and m/z 318.00 for the protonated internal standard, [d3-THC + H+]. The method proved to be precise for THC, in terms of both intra-day and inter-day analyses, with coefficients of variation less than 10%, and the calculated extraction efficiencies for THC ranged from 76 to 83%. Calibration standards spiked with THC between 2 and 100 ng/mL showed a linear relationship (r2 = 0.999). The method presented was applied to the oral fluid samples taken from the volunteers during the largest music event in Portugal, named Rock in Rio-Lisboa. Oral fluid was collected from 40 persons by expectoration and with Salivette®. In 55% of the samples obtained by expectorating, THC was detected with concentration ranges from 1033 to 6552 ng/mL and in 45% of cases THC was detected at concentrations between 51 and 937 ng/mL. However, using Salivette® collection, 26 of the 40 cases had an undetectable THC. 相似文献

Unarmed Utopia Revisited: The Resurgence of Left-of-Centre Politics in Latin America 总被引:1,自引:0,他引:1
Francisco Panizza 《Political studies》2005,53(4):716-734
This paper seeks to examine the extent to which left-wing forces are making a comeback in Latin America and to draw out the political implications of their political ascendancy. It argues that while left-of-centre parties have developed a persuasive critique of the failures of liberal democracy and economic neoliberalism in the region, there is as yet no conceptual clarity or distinct policy initiatives materialising from the left's promises of deepening democracy and implementing an alternative economic model. When in power, left-of-centre parties have followed a strategy of 'bending and moulding' existing political institutions and the free-market economic model rather than attempting radical political and economic reforms. This paper concludes that left-of-centre parties are right in accepting that there is little room in the region for an anti-systemic model and that instead the emphasis should be placed on making states, markets and democracy work better to secure development, address social demands and attack the root causes of discrimination and inequality. But leaving behind old certainties and adapting to the new political and economic environment has come at the cost of a loss of intellectual confidence, ideological clarity and weakened identities. 相似文献

The paper explores the aerial dimension of policing and surveillance. It does so by drawing upon select results from a large‐scale survey conducted in 2017 among professional (public and private) drone users in Switzerland. Focusing in particular on the police, the paper shows that the technology not only generates novel ways of looking down from above, but also of looking up from below, thus instilling a kind of air‐mindedness among the police. In making the airspace explicit as an object, and stake of imaginaries, concerns and practices, drones mediate novel ways of relating to the air, understanding it, approaching it and acting in relation to it. 相似文献

Abstract We study the degree of convergence or divergence in fiscal decentralization in the European Union over the period 1995–2015 using a club convergence approach. First, we analyze non-central expenditure and revenue as percentages of GDP, of total expenditure and of total revenue. The results for the EU-15 countries indicate some clustering, with three clubs formed when using GDP and four to five when using total revenue or expenditure. Second, we study the gap between expenditure and revenue as a proxy of fiscal responsibility. This results in three and two clubs respectively, with Denmark as the divergent country with the highest gap. Finally, we analyze potential unions of clubs and transitions. We also interpret our results taking into account variables found in the literature as determinants of fiscal decentralization. These results show how European countries are quite heterogeneous in terms of fiscal federalism and decentralization, with greater convergence in fiscal responsibility than in the other magnitudes. 相似文献

The risk for depression increases as Hispanic youth acculturate to U.S. society. This association is stronger for Hispanic girls than boys. To better understand the influence of culture and family on depressive symptoms, we tested a process-oriented model of acculturation, cultural values, and family functioning. The data came from Project RED, which included 1,922 Hispanic students (53?% girls; 86?% were 14?years old; and 84?% were U.S. born) from Southern California. We used data from 9th to 11th grade to test the influence of acculturation-related experiences on depressive symptoms over time. Multi-group structural equation analysis suggested that both family conflict and cohesion were linked with depressive symptoms. Hispanic cultural values were associated with family cohesion and conflict but the strength and direction of these relationships varied across cultural values and gender. For girls and boys, familismo and respeto were associated with higher family cohesion and lower family conflict. Moreover, gender roles were linked with higher family cohesion in girls but not in boys. These results indicate that improving family functioning will be beneficial for boys' and girls' psychological well-being. This may be achieved by promoting familismo and respeto for boys and girls and by promoting traditional gender roles for girls. 相似文献
