This study examined the in vitro stability of 6-acetylmorphine (6AM) in horse blood, sheep vitreous humour (VH) and homogenised deer muscle stored under different storage conditions. The stability of 6AM in horse blood is of interest because many toxicological laboratories utilise this matrix for the preparation of blood calibration and check standards and the latter are typically stored during routine use. Data on the storage stability of 6AM in human VH is extremely limited and no data has been reported in muscle. In the absence of human samples, 6AM stability was demonstrated in sheep vitreous and deer muscle. Blood and VH were stored with and without NaF at room temperature (RT), 4 and -18°C for 84 days. Muscle tissue homogenates were prepared in water with and without NaF and also in phosphate buffer (pH 6.0) containing NaF. Homogenates were stored for 31 days at RT, 4 and -18°C. Morphine and 6AM were extracted using SPE and quantified by GC-ion trap-MS/MS. In the absence of NaF, 6AM could not be detected after 7 and 14 days in blood stored at RT and 4°C, respectively. Although at -18°C 6AM was stable for 7 days (12% loss), only 54% was detected by day 84. The addition of NaF to horse blood increased 6AM stability substantially at every temperature. Further, the rate of degradation was found to be significantly slower in blood preserved with 2% NaF compared with 1% NaF (p=.05). 6AM was stable for the study period in preserved blood (1 and 2% NaF) stored at -18°C. For laboratories utilising horse blood in the preparation of standards, preservation with 1% NaF (minimum) and storage at -18°C is recommended. The addition of NaF to VH was essential for 6AM stability. Irrespective of temperature substantial losses (≥ 42%) were observed in unpreserved sheep VH by day 7. In preserved VH the concentration declined by only 22% on day 7 following storage at RT and no loss observed in VH stored at 4 and -18°C at the same time. In muscle, 6AM was stable for 7 days in preserved samples stored at RT and in all samples stored at 4°C and below. The addition of NaF increased the stability of 6AM substantially in muscle. The increased stability of 6AM in VH and muscle preserved with fluoride was attributed to inhibition of bacterial action and the subsequent reduction in the rate of putrefaction of these tissues. 相似文献

The eightieth anniversary of the Beveridge inquiry is a timely moment to consider how the landmark report is used within contemporary UK politics. Calls for a ‘new Beveridge’ reflect a desire for a rupture with the past and the creation of a radical new welfare consensus. But this reflects a misunderstanding: Beveridge's approach was organic in nature, building on decades of experimentation, politically contested rather than consensual, and intellectually pluralist rather than moored to a single ideological worldview. The real insight Beveridge offers us today flows not from his substantive agenda—which was rooted in a particular set of historic circumstances—but as an approach to securing social reform. Successful welfare advances over the last generation have drawn on these ‘Beveridgean instincts’. Rather than calling for a new twenty-first century blueprint to be handed down from above, reformers should build on experimentation and successful incremental change, from within the UK and abroad. 相似文献

In 2019, the family treatment court (FTC) best practice standards (the Standards) were published to clarify attributes of FTC programs associated with superior child, parent, and family outcomes. The Standards cover the breadth of FTC operations including program structure and leadership, substance use treatment and complementary services, and behavioral responses to participants. This study aimed to develop an instrument (the Model Standards Implementation Scale; “MSIS”) that stakeholders can use to assess implementation of the Standards by individual FTCs. The MSIS balances usability with scientific validity. Interrater reliability (IRR), internal consistency, and several types of validity were assessed. Results indicated moderate to strong IRR, high internal consistency, mixed known groups validity depending on Standard, and high convergent and divergent validity. Initial findings suggest good validity and usability of the MSIS for evaluating FTC Standards' implementation. Notably, the process of using the tool functioned to educate FTC team members on the Standards. Although implementation of the MSIS is a resource-intensive process, the opportunity to receive constructive feedback proved to be an effective incentive for initial and subsequent participation in the evaluation among FTCs. Future research is needed to examine predictive validity, including association between Standards' implementation and family outcomes in FTCs. 相似文献

This paper is situated within the rhetorical turn in political science and investigates the discourses constructed by Trotskyist parties in order to justify the policy of electoral participation despite poor electoral performance. A wide range of texts are examined from eight organizations that contested seats in the 2010 UK General Election. The thrust of Trotskyist discourse downplayed dismal vote totals, contextualizing them by reference to pro-Labour tactical voting and elaborating a variety of benefits that emerged from electoral participation. It is argued that such analysis could usefully be incorporated into the study of party responses to electoral problems and setbacks. 相似文献

See No Evil,Hear No Evil? Assessing Corruption Risk Perceptions and Strategies of Victorian Public Bodies 下载免费PDF全文
Zeger van der Wal Adam Graycar Kym Kelly 《Australian Journal of Public Administration》2016,75(1):3-17
This paper critically examines qualitative survey data from 36 Victorian public sector bodies on their perceptions of corruption risks, and strategies to mitigate these risks, as well as the integrity mechanisms in place. The findings indicate that even though corruption does not seem to be prevalent in these bodies it is not on their radar either, though fraud prevention was significantly present. The paper identifies international best practices of integrity management and inculcation of public service ethos in developed countries, and stresses three vital elements or pillars that combine both the ‘values’ and ‘compliance’ based approaches. These pillars are as follows: (1) specific corruption prevention programs and strategies that are additional to but complement existing anti‐fraud programs; (2) targeted anti‐corruption training, both for employees and for the public; and (3) effective leadership engagement and commitment to an ethical culture (Tone at the Top). 相似文献

This practical note discusses some of the challenges evaluators face when their values clash with those of their employer. A case example where the author was commissioned to complete an evaluation for a community development project within a welfare-minded NGO highlights evaluation issues for welfare-minded NGOs attempting to deliver community development programmes. A fundamental issue is the differing interpretation of key terms including evaluation, participation, and empowerment. The note discusses how the author attempted to navigate between maintaining community development principles in the evaluation process while at the same time fulfilling quantitative evaluation requirements mandated by the organisation and funders. 相似文献

Co‐parenting in a Highly Conflicted Separation/Divorce: Learning about Parents and their Experiences of Parenting Coordination,Legal, and Mental Health Interventions 下载免费PDF全文
Sixty high‐conflict separated/divorced co‐parents completed surveys investigating characteristics and dynamics (narcissism, empathy, conflict) that were examined in relation to co‐parenting style and parents' experiences of parenting coordination, legal, and mental health interventions. Study findings for this sample did not support common notions found in the literatures on parenting coordination and high‐conflict divorce that suggest these parents are often narcissistic or low in empathy. Findings pertaining to all high‐conflict participant experiences revealed the presence of common elements across aspects of practitioners and interventions with which they were both satisfied and dissatisfied. 相似文献

Bernie Mayer's latest book is an excellent journey into seven key dilemmas in conflict. Mayer devotes a chapter to each of the following dilemmas: Competition and Cooperation, Optimism and Realism, Avoidance and Engagement, Principle and Compromise, Emotions and Logic, Impartiality and Advocacy, and Autonomy and Community. In this review, I suggest that the book is a thorough guide through seemingly diverse and opposing conflict theories. I go through each chapter and detail how Mayer sees these concepts as interwoven instead of oppositional. He walks his readers through what have been thought of as distinctive, even opposing, approaches, theories, and concepts of conflict. The review uses points and quotes from all seven dilemmas to show the depth of Mayer's analysis and the numerous benefits to theorists and practitioners of reading and rereading his book. 相似文献
