2,5-Dimethoxy-4-bromoamphetamine (DOB) is one of the potent hallucinogenic phenylalkylamines, whose ingestion has already caused several deaths reported all over the world. However, there is unsufficient information on DOB properties based on controlled pharmacokinetic studies available. The aim of this study was to clarify the distribution profile of DOB and its phenolic metabolite 2-methoxy-5-hydroxy-4-bromoamphetamine (2M5H4BA) in blood and biological tissues of experimental rats. The rats were administered a 20 mg/kg dose of DOB·HCl by oral ingestion or subcutaneous injection. Plasma and brain, liver and lung tissues were collected at 0.5, 1, 2, 4, 8, 16, and 32 h after dosing (three animals per time point). The samples were prepared by a liquid–liquid extraction procedure and the extracts were assayed by GC–MS. After per oral application, DOB peak plasma level of 320 ng/mL was reached after one-hour post dosing as well as 2M5H4BA peak concentration of 203 ng/mL. A rapid phase of DOB absorption, 2M5H4BA formation and their tissue distribution during the first two hours after application were followed by a slow decrease rate of the elimination process until 32 h. After subcutaneous application, high plasma levels of the unchanged parent drug and relatively reduced formation of its metabolite 2M5H4BA were observed. DOB maximum plasma concentration of 1143 ng/mL was reached after one-hour post application, whereas its metabolite peak level after 8 h was 213 ng/mL. The concentration profiles of both compounds in plasma after per oral and subcutaneous administration revealed the existence of significant first pass effect after per oral administration that significantly affected DOB bioavailability. DOB tissue concentrations exceeded plasma and the highest values were found in the lungs, where drug accumulation occurred with prolonged retention till 32 h after subcutaneous dose. Although the plasma/tissue transfer was more effective for the lipophilic parent drug than for its hydroxylated metabolite 2M5H4BA, the metabolite tissue levels were significant. The hallucinogenic potential of 2M5H4BA appearing in brain remains unclear as nothing is known about its pharmacological activity at present. 相似文献

The article examines the recent Court of Appeal judgment in Bree, in which the court considered the guidance that should be given to a jury when the complainant is intoxicated at the time of an alleged rape. As well as analysing the reasoning of the court in Bree, the judgment is placed in context by examining factors, such as social attitudes, that influence juror decision-making in rape cases. It also examines the suggestion made by the court in Bree that further law reform in this area would represent 'patronising interference' in the lives of women. 相似文献

Representation beyond people: Lobbying access of umbrella associations to legislatures and the media
Wiebke Marie Junk 《管理》2019,32(2):313-330
Lobbying access to policy discussions determines how political interests are voiced and potentially exert influence. This article addresses whether access to the national legislature and the media favors umbrella organizations, which represent interests of their member groups. It theorizes that the role of umbrellas goes beyond signaling a large individual membership or constituency of people, but that umbrellas are distinct in transmitting interests from other organizations. This function is expected to be valuable in exchanges with legislators who seek efficiency, input legitimacy, and policy implementation, but less valuable in the media arena. Using a new data set on lobbying by 286 groups on 12 issues in the United Kingdom and Germany, the article serves support for this theory: Umbrellas enjoy higher legislative access, but lower media access than groups without member organizations, irrespective of their individual membership or claimed constituency. The findings have implications for how we understand and study political representation. 相似文献

This study reports on the effectiveness of a year-long field experiment involving training in transformational and transactional leadership in the public and private sectors. Using before and after training assessments by employees of several hundred Danish leaders, the analysis shows that transformational leadership training is associated with increases in behaviors linked to both transformational leadership and the use of verbal rewards, but only for public sector organizations. There is no impact in private sector organizations. Transactional leadership training appears to be equally effective in stimulating the use of pecuniary rewards in both public and private organizations. 相似文献

Self‐driving cars (also known as driverless cars, autonomous vehicles, and highly automated vehicles [HAVs]) will change the regulatory, political, and ethical frameworks surrounding motor vehicles. At the highest levels of automation, HAVs are operated by independent machine agents, making decisions without the direct intervention of humans. The current transportation system assumes human intervention though, including legal and moral responsibilities of human operators. Has the development of these artificial intelligence (AI) and autonomous system (AS) technologies outpaced the ethical and political conversations? This paper examines discussions of HAVs, driver responsibility, and technology failure to highlight the differences between how the policy‐making institutions in the United States (Congress and the Public Administration) and technology and transportation experts are or are not speaking about responsibility in the context of autonomous systems technologies. We report findings from a big data analysis of corpus‐level documents to find that enthusiasm for HAVs has outpaced other discussions of the technology. 相似文献

The rhetoric of then U.S. President‐elect Donald Trump and Philippines' President Rodrigo Duterte had triggered a shift in global political discourse (Greene, 2016 ). This study examines their responses on three similar crises: disrespectful remarks towards women, associations with controversial political figures, and remarks threatening geopolitical relations. Data from prestige publications, Washington Post (U.S.) and the Philippine Daily Inquirer, were analyzed during the acute stage of each crisis. Findings showed that both men employed confusing strategy combinations in their crisis responses. Despite incoherent application and contradictory strategies, they survived threats to their image as evidenced by poll results. New strategies (diversion and logorrhea) and a strategy amplifier (machismo) were uncovered. These strategies tapped on ambiguity and were found to be successfully employed in a post‐truth landscape. This study builds on Benoit's ( 2006 ) argument that “any attempt by a president to repair a damaged image … clearly merits scholarly attention” (p. 138). 相似文献

Abstract Late nineteenth-century England saw the development of a number of campaigns and social movements which were connected by both a hostility towards the medical profession and by the use of discourses of purity and sanitary reform. This article explores the involvement of women within these movements, analysing their activism as an aspect of social purity feminism. It argues that many of these movements drew on widespread female anxiety regarding male violence – both physical and sexual – towards women. The anti-medical feminists claimed that some pieces of ‘sanitary’ legislation represented a state-sanctioned violation of the bodies of women and children. Finally, this article analyses the use made, by some of these activists, of the discourses of sanitary reform to challenge the gender ordering associated with the reason/nature dualism in Victorian society. 相似文献

This research re‐evaluates the female marginalisation thesis through an examination of the changing nature of work in Latin America and of women's incorporation into paid employment. We combine labour market segementation theory, which explains the emergence of low level occupations in terms of capitalist restructuring, with feminist theory, which explains why women become concentrated in inferior positions. We operationalise this reconceptualisation through an empirical analysis of women's and men's relative occupational position across economic sectors and through time in Ecuador. A key finding is that women's and men's occupations are differentiated in terms of control over economic resources and control over the labour process and that this worsens over time. 相似文献
