In this study, a new method was developed for the impurity profiling of illicit MDMA tablets. The extraction efficiency, linearity, repeatability and reproducibility of the method were evaluated. Eighty two MDMA tablets coming from presumed unrelated large seizures in 2004 (n >500 tablets) were analyzed by gas chromatography mass spectrometry (GC-MS) in order to assess the discrimination power of the method. The latter was found to be practical, robust, relatively easy to perform, highly discriminative and yielding good chromatography. In addition, some new impurities were detected and identified. Their chemical structures and mass spectra are reported.  相似文献

This research examines the data from private polls conducted during Vicente Fox's presidential campaign through the lenses of the "modernization" of campaigning, the creation of image in the modern Mexican presidency, and the survey tools used by the campaign to achieve a historic presidential victory in 2000. Fox's campaign team used polling to determine the potential of the Mexican public to be persuaded by an opposition candidate, to provide a continuous update on how the campaign strategy was working, to assist in solidifying Fox's image and message of change (rather than promoting his policy agenda), and to target demographic groups that were perceived to be important electoral partners. These findings suggest that public opinion polling is a useful tool in Mexico to combat longstanding corporatist structures used to favor the PRI. Presidential campaigns in Mexico are beginning to resemble modern campaigns in other mature democracies in their use of private polling data; future Mexican campaigns will become more image- and personality-based.  相似文献

There has been growing academic and public interest in corporate political lobbying in both the UK and EU in recent years. In Britain, links between politicians and commercial interests have been one of the areas examined by the Committee on Standards in Public Life (‘the Nolan Committee’ and now ‘the Neill Committee’). A visible but under‐researched aspect of political lobbying by firms and other groups is the range of activities that take place at annual party conferences. An exhaustive study of these activities at the three main British party conferences between 1994–97 is reported, covering the period from Tony Blair's first appearance as party leader to the aftermath of the 1997 General Election. There is clear growth of visible lobbying, particularly at the Labour conferences, over the period leading up to the election, and a dropping off in 1997; particularly at the Conservative conference. The implications of the results for organisations, and particularly for public affairs practitioners, are considered. Copyright © 2002 Henry Stewart Publications  相似文献

Conventional methods for the identification of different body fluids like blood, semen and saliva from biological stains involve immunological or enzymatic detection of certain proteins. In this study, we investigated potential RNA markers with the aim of developing Real-Time polymerase chain reaction (PCR) based methods to allow differentiation between several body fluids. Total RNA samples from artificially stained swabs and from various pieces of evidence from case work were extracted, amplified and analyzed with several RNA markers. Three assays detecting the body fluids of interest were selected: hemoglobin-alpha locus 1 (HBA), kallikrein 3 (KLK) and mucin 4 (MUC). With this approach, we demonstrate that specific Real-Time PCR assays are useful in identifying the source of the biological stain. Furthermore, RNA profiling of various body fluids was even possible on samples stored over a long period of time at ambient temperature. The stability and sensitivity of the applied method outlines a novel application for Real-Time PCR within the forensic field.  相似文献

Laws for Sale: Evidence from Russia   总被引:2,自引:0,他引:2  
How does regulatory capture affect growth? We construct measuresof the political power of firms and regional regulatory captureusing microlevel data on the preferential treatment of firmsthrough regional laws and regulations in Russia during the period1992–2000. Using these measures, we find that: (1) politicallypowerful firms perform better on average; (2) a high level ofregulatory capture hurts the performance of firms that haveno political connections and boosts the performance of politicallyconnected firms; (3) capture adversely affects small-businessgrowth and the tax capacity of the state; and (4) there is noevidence that capture affects aggregate growth.

This work develops a detailed STR database from 11 population samples and samples from paternity analyses from different districts of Belarus. The combined data on 2020 individuals form a total database for the country, with the exclusion power of 99.987% based on 11 STR loci. Possible differentiation in allele frequencies between population samples, small in terms of F-statistics and undetectable by standard statistical tests, is discussed.  相似文献

This paper is the fifth in a series of six in relation to the development of a harmonised method for the profiling of amphetamine [L. Aalberg, K. Andersson, C. Bertler, H. Borén, M.D. Cole, J. Dahlén, Y. Finnon, H. Huizer, K. Jalava, E. Kaa, E. Lock, A. Lopes, A. Poortman-van der Meer, E. Sippola, Development of a harmonised method for the profiling of amphetamines I. Synthesis of standards and compilation of analytical data, Forensic Sci. Int. 149 (2005) 219-229; L. Aalberg, K. Andersson, C. Bertler, M.D. Cole, Y. Finnon, H. Huizer, K. Jalava, E. Kaa, E. Lock, A. Lopes, A. Poortman-van der Meer, E. Sippola, J. Dahlén, Development of a harmonised method for the profiling of amphetamines II. Stability of impurities in organic solvents, Forensic Sci. Int. 149 (2005) 231-241]. The third paper [K. Andersson, K. Jalava, E. Lock, L. Aalberg, Y. Finnon, H. Huizer, E. Kaa, A. Lopes, A. Poortman-van der Meer, M.D. Cole, J. Dahlén, E. Sippola, Development of a harmonised method for the profiling of amphetamines III. Development of the gas chromatographic method, Forensic Sci. Int., in press] dealt with the optimisation of the gas chromatographic and detection methods whereas the fourth paper [K. Andersson, K. Jalava, E. Lock, Y. Finnon, S. Stevenson, L. Aalberg, H. Huizer, E. Kaa, A. Lopes, A. Poortman-van der Meer, M.D. Cole, J. Dahlén, E. Sippola, Development of a harmonised method for the profiling of amphetamines IV. Optimisation of sample preparation, Forensic Sci. Int., in press] concerned the optimisation of the extraction method prior to GC analysis. This paper is a study of the optimised method in order to determine its stability. Investigations of within and between day variations were carried out in four laboratories. Moreover, variations between laboratories were also determined. Both flame ionisation detector (FID) and MS detection were used. One laboratory studied nitrogen-phosphorous detector (NPD) detection as well. For this task, 12 batches of amphetamine were prepared. Six of them were synthesised via the Leuckart route, three via the nitrostyrene route and three via the reductive amination route [A.M.A. Verweij, Impurities in illicit drug preparations: amphetamine and methamphetamine, Forensic Sci. Rev. 1 (1989) 2-11]. Taking into account all studied target compounds and the average results from four laboratories, the within day variation was around 6% for FID and 5% for MS, the between days variation was around 10% for FID and 8% for MS. For NPD detection, within day variation was 5% and between days variation 9% (only one laboratory). Finally, the inter-laboratory variation was about 12% for FID (four laboratories) and 10% for MS (three laboratories).  相似文献

Diplomatic relations between Russia and South Africa were established in 1992, before South Africa's transition to democracy was completed. This move was perceived as a betrayal by many in both countries and beyond. For many decades the Soviet Union supported the African National Congress in its fight against the apartheid regime. South Africa's National Party government, in its turn, presented the USSR as the main force behind the ‘total onslaught’ – an all-out war purportedly waged against South Africa by international communism. Yet it was with the National Party government that the Russians established diplomatic relations. This article looks into the reasons for this change of heart in Moscow and Pretoria, discusses the political forces behind the decision to establish diplomatic relations, and analyses the process that led to this event and the results of establishing diplomatic relations the way it happened and at the time it happened for both countries.  相似文献
