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

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

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

The authors previously explored invention licensing from the university's perspective. In this paper we focus on the process from the perspective of firms activity engaged in licensing technology. A survey of industry licensing professionals addresses why some firms license technologies from universities and why others do not. The paper then considers the stage of development of university technologies, the characteristics of their licensing contracts, and sources of information about university technologies, all to better understand how the process works and what advantages and disadvantages it offers to all participants. 相似文献

The true impact of heat-induced changes in human bone regarding their sex estimation has not been comprehensively documented having a potentially negative impact on forensic anthropology. The objective of this paper was to evaluate how heat exposure affects sex estimation based on both morphological and metric features. The study focused in both low-to-medium intensity burns and high intensity burns. Selected sexually dimorphic features were analysed in 51 experimentally burnt skeletons from the 21st Century Identified Skeletal Collection. Bones were burnt to maximum temperatures between 450 °C and 1050 °C achieved after 75 to 257 min. Morphological methods tested in this study comprised the recommendations for hipbone features from Buikstra and Ubelaker (1994) and from Bruzek (2002). On the other hand, metric references tested here were the ones from Wasterlain (2000), Curate et al. (2016) and Gonçalves et al. (2013) focused on the humerus, femur, calcaneus and talus. Agreement was tested with Gwet’s AC1 test and was further assessed by calculating the relative amount of perfect agreements. Results demonstrated that heat-induced changes affected not only the scoring of morphological features burnt at high temperatures but also the scoring of features burnt at lower intensities. On the other hand, metric features were only considerably affected in high intensity burns, no major changes being documented for low-to-medium intensity burns. For low-to-medium intensity burns, the Bruzek and Curate et al. methods revealed a better agreement between the pre- and post-burning scores. For high intensity burns, better agreement was obtained by using the Bruzek (2002) and Gonçalves et al. (2013) methods. As expected, heat-induced warping, fracture and metric change had a major impact on the pre- and post-observations’ agreement. Contrary to what has been systematically assumed over the years, this impact is also quite substantial in bones burnt at low-to-medium burn intensities so caution is advised during the analysis of this kind of burnt skeletal material. 相似文献

Existing research highlights that families face geographic, social, and psychological constraints that may limit the extent to which competition can take hold in school choice programs. In this paper, we address the implications of such findings by creating a network of student flows from 11 cohorts of eighth‐grade students in the Chicago Public Schools (CPS). We applied a custom algorithm to group together schools with similar sending and receiving patterns, and calculated the difference in mean achievement between a student's attended and assigned high schools. For all identified school groupings, we found that the students were on average moving to higher achieving schools. We also found that the movement toward higher achieving schools of the top achievement quartile of students was over twice as large as that of the bottom quartile, but that the flows of both the highest and lowest achieving student quartiles were toward higher achieving destinations. Our results suggest that student movements in CPS between the years of 2001 to 2005 were consistent with creating market pressure for improvement as well as increasing segregation by achievement. However, further research into how schools responded to those movements is required to make inferences about the level or consequences of competition generated by choice‐related reforms during that time. 相似文献

The residential aged care industry in Australia will expand rapidly over the next 10 years leading to substantial increases in government expenditure. Recent and future reforms are likely leading to changes in the structure of the industry with a potential impact on quality of care. The purpose of this paper is to stimulate broader public debate, based on the available evidence, about the preferred structure of this important industry. It examines the literature on the impact structure has on the quality of services and compares this with a fresh analysis of current trends. The paper argues that future policy should be evidence based and explicit about the structure of the industry that will emerge from current policy reforms. 相似文献

Correctional staff job burnout is costly to all involved. As such, it has generated a growing body of research. This study reviewed 53 empirical studies of correctional staff burnout and two review articles published between 1981 and 2014. The majority of studies focused on staff working in a variety of institutional positions, fewer studies focused exclusively on the subgroup of correctional officers, and even fewer focused on a different subgroup. The majority of studies also involved staff at US government-run adult prisons. Most but not all studies utilized Maslach’s Burnout Inventory. Research on the antecedents of job burnout among correctional staff is more common than research on the possible consequences or outcomes of job burnout. Interestingly, despite the empirical emphasis on antecedents of burnout, there has been almost no research on effective interventions designed to deal with correctional staff burnout. Based on this narrative review, significant gaps remain in the research on correctional staff burnout. 相似文献
