This paper describes the analytical methodology for the determination of MDMA, MDA, MDEA and MBDB in oral fluid. After a liquid–liquid extraction, the analysis was carried out by high performance liquid chromatography (HPLC), with fluorescence detection. The detector wavelength was fixed at 285 nm for excitation and 320 nm for emission. The mobile phase, a mixture of phosphate buffer (pH = 5) and acetonitrile (75:25), and the column, Kromasil 100 C8 5 μm 250 mm × 4.6 mm, allowed good separation of the compounds in an isocratic mode in only 10 min. The method was validated and showed good limits of detection (2 ng/mL) and quantitation (10 ng/mL) for all the amphetamine derivatives. No interfering substances were detected. A stability study of these compounds in oral fluid stored at three different temperatures (−18, 4 and 20 °C) over 10 weeks was conducted, showing a time-dependent degradation of the four compounds.  相似文献

The purpose of the present study is to examine how conflict resolution styles between one family dyad is related to other family dyads and how conflict resolution styles within these family dyads are related to conflict resolution styles in one relationship outside the family—adolescents' romantic relationships. Late adolescents (n = 217) were asked to report their perceptions of three resolution styles used in interparent, mother–adolescent, father–adolescent, sibling, and romantic couple conflicts. Based on the cases with complete data (n = 163), path analyses indicated that both direct and indirect relationships exist between these dyadic relationships: (1) Resolution styles utilized in the interparent subsystem were found to have a direct relationship with mother–adolescent and father–adolescent resolution and an indirect relationship with sibling and romantic couple resolution. (2) Mother–adolescent and father–adolescent resolution were found to have a direct relationship with sibling and romantic couple resolution. (3) Sibling resolution was found to have a direct relationship with romantic couple resolution for negative resolution styles, but not for the positive resolution style of compromise.  相似文献

The Clinton administration's economic diplomacy has been more aggressive, politicized and controversial than that of any recent US administration. We examine its application to the European Union (EU) and seek to answer the question: what makes Europe different? Put another way, why has the US pursued cooperation on “behind-the-border” issues such as competition policy, standards and investment rules, and eschewed export promotion? We offer three explanations. First, the EU's market is unique: it is a mature, but lucrative one for large US-owned firms concerned more with behind-the-border issues than with market access issues. Second, American companies who have invested heavily in Europe have developed their own political links to the EU, particularly through the EU Committee of the American Chamber of Commerce. Third, these same companies have a powerful influence over US policy towards Europe as well as EU policymaking. Our analysis develops these three hypotheses, and also offers an assessment of the progress and meaning of the Transatlantic Business Dialogue.  相似文献

We examine factors that affect the supply of and demand for female cabinet ministers in Latin America and seek to understand the frequency with which women join cabinets and the types of portfolios women receive. Our analysis covers 18 Latin American democracies from 1980 to 2003. We find that presidents from parties of the left appoint more women. Increases in the percentage of women in the legislature and higher human development correlate with more women in the cabinet. Intense partisan competition increases the likelihood that a cabinet will contain a woman. Women are more likely to receive high-prestige cabinet posts from leftist presidents and when the percentage of women in the legislature increases. In addition, an international diffusion effect appears to explain the rapid expansion of women in Latin American cabinets.  相似文献

In Portugal the republican regime broke ties with the monarchy, advocating the need to reassume the national principle, as well as the secularization of its foundations and of the state itself. With the establishment of the new parliamentary republic in 1910 and the debate between republic and monarchy, the supporters of parliamentarianism saw a rupture in the composition and relationship between the powers foreseen in the constitutional charter of 1826, which gave more power to the king during the period of the constitutional monarchy. This made republicans grow closer to the constitution of the French Third Republic, the Brazilian constitution of 1891, the 1812 constitution of Cadiz and the 1822 Portuguese constitution, owing to the fact that these were radical liberal constitutions that conferred national sovereignty. The republicans put forward various arguments both to defame and to defend parliamentarianism. Nevertheless, as in the constitution of 1822, the republican constitution of 1911 stipulated that the congress (the Portuguese Parliament) would be, in theory, the only body that could regulate the political guidelines of the republic.  相似文献

Voela and Tamboukou use Slavoj ?i?ek’s notion of the symptom as a lens through which to look at representations of female figures in Greek literary texts of the early twentieth century by Gregorios Xenopoulos. In mapping the construction of the figure of the modern woman in the matrix of discourses, fantasies and power relations of fin-de-siècle Greece, they draw on psychoanalytic insights, interrupted by Foucauldian interventions. Following Judith Butler’s move of making trouble they attempt to open up a dialogic space between psychoanalytic and Foucauldian approaches to the female subject, contextualized in a specific social, historical and cultural milieu. It is in this context that they discuss, first, how feminine and masculine subjectivities are represented in man’s speech; second, how unintended excesses and interruptions occur in the problematic representation of women; and, third, how madness and ultimately death come to play a significant role in the power relations between the sexes.  相似文献

We discuss how far accountability practices may be relevant to the success of independent regulators in countries without a tradition of administrative autonomy. We develop a conceptualisation of agency accountability failures and develop an analytical framework to examine the life and termination of the Spanish regulatory agency for telecommunications, CMT (Comisión del Mercado de las Telecomunicaciones - Telecommunications Market Commission). We argue that the CMT’s termination was related, among other reasons, to accountability failures in its institutional design. The paper relies on a variety of sources, including legislation, literature, media coverage, and semistructured interviews with agency officials and several stakeholders.  相似文献
