A method for the simultaneous determination of cocaine (COC) and cocaethylene (CE) in human hair was developed, using solid-phase microextraction (SPME) and gas chromatography-mass spectrometry (GC-MS) as analytical technique to identify and quantify the drugs. Selected ion monitoring (SIM) mode was used to obtain higher sensitivity. The deuterated-labeled analogues were used as internal standards. The detector response was linear for the drugs studied over the range 0.4-15 ng/mg, with correlation coefficients higher than 0.995. The coefficients of variation oscillated between 0.65% and 14.18% and the accuracy was in the range from 0.73% to 11.20%. The limits of quantitation and detection were found to be acceptable. Finally, this method was applied to 15 hair samples from cocaine users, obtaining positive results in all cases. The mean concentrations were 5.39 ng/mg (range: 0.43-8.98 ng/mg) for cocaine and 1.11 ng/mg (range: 0.42-2.23 ng/mg) for cocaethylene. 相似文献

Allele frequencies for 15 short tandem repeats (STRs) autosomal loci (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818 and FGA, included in the AmpFLSTR Identifiler, Applied Biosystems) were studied in the city of Maracaibo, Venezuela and were compared with other published Latin-American populations for the same loci. Population and forensic parameters were estimated. 相似文献

It is common wisdom that public sector wages are not determined in the same way as private sector wages. At the same time, the empirical evidence available for OECD countries finds a strong positive correlation between public and private sector wages. In this paper, we develop a model that is consistent with a political economy view of the determination of public sector wages and employment, while being consistent with the said empirical evidence. Public finance constraints are crucial: In booms, governments expand employment and wages, while in downturns, lack of tax revenues forces the government to cut back the wage bill. 相似文献

Cuba faces a development dilemma: it promotes equity and human capital while failing to deliver economic growth. For the government, the country's equity and human capital achievements are a source of pride, a sign that its priorities are right. This essay argues instead that this “equity without growth” dilemma is a sign of malaise. Theory and evidence suggest that high levels of equity and human capital should produce high levels of economic growth. Because growth is often weak or negative, some onerous barriers to development must be present. These barriers, it is argued, are restrictions on property and political rights. By comparing Cuba and China across two sectors, the bicycle industry and Internet access, this article shows how these restrictions have hindered growth. It also assesses how Cuba's latest economic reforms, the so‐called Lineamientos, will address Cuba's development dilemma. The impact may be minimal, but perhaps more lasting than previous reforms. 相似文献

Through the in‐depth ethnographic study of one squatter neighborhood in Montevideo and its leader's political networks, this article illustrates a successful strategy through which some squatter neighborhoods have fought for their right to the city. This consists of opportunistic, face‐to‐face relationships between squatter leaders and politicians of various factions and parties as intermediaries to get state goods, such as water, building materials, electricity, roads, and ultimately land tenure. Through this mechanism, squatters have seized political opportunities at the national and municipal levels. These opportunities were particularly high between 1989 and 2004, years of great competition for the votes of the urban poor on the periphery of the city, when the national and municipal governments belonged to opposing parties. In terms of theory, the article discusses current literature on clientelism, posing problems that make it difficult to characterize the political networks observed among squatters. 相似文献
