Doping control laboratories accredited by the World Anti-Doping Agency (WADA) require criteria that allow endogenous steroids to be distinguished from their synthetic analogues in urine. Methodology based on "looking outside the metabolic box" was used in this study to identify diagnostic urinary markers of 4-androstenediol (4-ADIOL) administration. Androst-2,4-diene-17-one and androst-3,5-diene-17-one are proposed to be formed in urine from acid-catalyzed hydrolysis of 4-ADIOL sulfoconjugate, a major phase II metabolic product of 4-ADIOL. The presence of these markers in the routine gas chromatography-mass spectrometry (GC-MS) steroid screen was suitable to identify samples requiring confirmation by gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS) - to measure the carbon isotope ratio (δ(13)C) of the androstdiene markers and confirm their likely synthetic origin based on depleted (13)C content.  相似文献

Purpose. The ideologically based view of intimate partner violence has traditionally influenced policy and practice in modern western nations and dominated cross‐national research and practice. This review considers the validity of the position statement of a British organization responsible for accrediting many male perpetrator programmes in the statutory, voluntary, and private sector as an example of this ideological influence. Method. The position statement, informed by the patriarchal view of partner violence, is evaluated using empirical evidence from various branches of the social sciences, including psychology, that have not been guided by the patriarchal view. Results. Overwhelming empirical evidence is presented, which refutes ideologically driven assumptions that have been put forward to guide current practice and evaluation of it. Conclusions. This review highlights the need to investigate intimate partner violence from a scientific and gender‐inclusive perspective. The implications for psychological practice are discussed.  相似文献

Editorial     
Were the Carmelite order to submit argument based on what itssisters do today, the result in Gilmour v Coats [1949] AC 426would be reversed: but not its finding that the efficacy ofprayer is non-justiciable. Sacramental efficacy is in the same boat. The theologians holdthat the ministers of the sacrament of matrimony are the couplethemselves. In times when the imbalance between the relativesocial positions of the sexes was extreme, the additional requirementof a priestly witness helped protect the weak position in whichthe wife might have found herself  相似文献

ABSTRACT

Ghana’s Petroleum Revenue Management Act 815 (amended to Act 893 in 2015) established the Public Interest and Accountability Committee (PIAC) in 2011 with the mandate to ensure accountability and transparency in the management and usage of oil and gas revenue. This paper critically examines the activities and operations of the PIAC from 2011 vis-à-vis its legally reposed mandate. It points to severe deficit in accountability but improvements in transparency in the management of oil and gas revenues in spite of the existence and operations of the PIAC. After eight years of operation, the PIAC continues to suffer monumental challenges that undermine its effectiveness in serving as an accountability and transparency initiative in Ghana’s oil and gas sector. The paper makes some recommendation based on the empirical challenges of the PIAC identified to strengthen the PIAC to deliver effectively on its mandate.  相似文献
