Some juveniles who engage in sexual offenses may have a paraphilia, a psychiatric disorder characterized by a pervasive pattern of deviant and impairing sexual fantasies, thoughts, and/or behaviors. Though there is no known cure for these conditions, paraphilias can be effectively managed using a multimodal treatment approach. This may include the use of psychotherapeutic and pharmacological treatment interventions, including antiandrogen medications. One such agent, leuprolide acetate (leuprolide), a luteinizing hormone-releasing-hormone agonist, has been shown to be effective in reducing paraphilic symptoms in adult patients. To date, however, there is no published data on its use and effectiveness in adolescent and young adult paraphilic patients. This study consists of a case report series of six young adult patients treated with leuprolide. All subjects had been diagnosed with at least one paraphilia (i.e., Pedophilia, Sexual Sadism, Frotteurism, and Paraphilia Not Otherwise Specified). All subjects had been refractory to treatment in a residential program for adolescent sex offenders prior to initiation of leuprolide. All six subjects reported a reduction in sexually deviant symptoms following treatment with leuprolide. Clinicians rated four as much improved and two as moderately improved. The treatment was well tolerated in all six subjects. This preliminary case series supports the conclusion that leuprolide deserves further examination as a potentially safe and effective component in the treatment of young adult patients with paraphilia.  相似文献

This article examines the way in which administrative courts and the National Ombudsman in the Netherlands seek to control administrative action, and is aimed at developing a heuristic model that can also be useful in a wider context. Two styles of control will be introduced: "coercive" and "cooperative." An exploratory empirical study was conducted of two administrative agencies, investigating the implementation process of court and ombudsman decisions. This article argues that it is likely that the policy impact of the courts and the ombudsman is directly related to their style of control. More empirical research is needed to evaluate this hypothesis.  相似文献

A rapid and sensitive method using LC-MS/MS triple stage quadrupole for the determination of traces of amphetamine (AP), methamphetamine (MA), 3,4-methylenedioxyamphetamine (MDA), 3,4-methylenedioxymethamphetamine (MDMA, “ecstasy”), 3,4-methylenedioxyethamphetamine (MDEA), and N-methyl-1-(3,4-methylenedioxyphenyl)-2-butanamine (MBDB) in hair, blood and urine has been developed and validated. Chromatography was carried out on an Uptisphere ODB C18 5 μm, 2.1 mm × 150 mm column (Interchim, France) with a gradient of acetonitrile and formate 2 mM pH 3.0 buffer. Urine and blood were extracted with Toxitube A® (Varian, France). Segmented scalp hair was treated by incubation 15 min at 80 °C in NaOH 1 M before liquid–liquid extraction with hexane/ethyl acetate (2/1, v/v). The limits of quantification (LOQ) in blood and urine were at 0.1 ng/mL for all analytes. In hair, LOQ was <5 pg/mg for MA, MDMA, MDEA and MBDB, at 14.7 pg/mg for AP and 15.7 pg/mg for MDA. Calibration curves were linear in the range 0.1–50 ng/mL in blood and urine; in the range 5–500 pg/mg for MA, MDMA, MDEA and MBDB, and 20–500 pg/mg for AP and MDA. Inter-day precisions were <13% for all analytes in all matrices. Accuracy was <20% in blood and urine at 1 and 50 ng/mL and <10% in hair at 20 and 250 pg/mg. This method was applied to the determination of MDMA in a forensic case of single administration of ecstasy to a 16-year-old female without her knowledge during a party. She suffered from hyperactivity, sweating and agitation. A first sample of urine was collected a few hours after (T + 12 h) and tested positive to amphetamines by immunoassay by a clinical laboratory. Blood and urine were sampled for forensic purposes at day 8 (D + 8) and scalp hair at day 60 (D + 60). No MDMA was detected in blood, but urine and hair were tested positive, respectively at 0.42 ng/mL and at 22 pg/mg in hair only in the segment corresponding to the period of the offence, while no MDA was detectable. This method allows the detection of MDMA up to 8 days in urine after single intake.  相似文献

Recent developments in German corporate governance   总被引:1,自引:0,他引:1  
This paper provides an overview of the German corporate governance system. We review the governance role of large shareholders, creditors, the product market and the supervisory board. We also discuss the importance of mergers and acquisitions, the market in block trades, and the lack of a hostile takeover market. Given that Germany is often referred to as a bank-based economy, we pay particular attention to the role of the universal banks (Hausbanken). We show that the German system is characterised by a market for partial corporate control, large shareholders and bank/creditor monitoring, a two-tier (management and supervisory) board with co-determination between shareholders and employees on the supervisory board, a disciplinary product–market, and corporate governance regulation largely based on EU directives but with deep roots in the German codes and legal doctrine. Another important feature of the German system is its corporate governance efficiency criterion which is focused on the maximisation of stakeholder value rather than shareholder value. However, the German corporate governance system has experienced many important changes over the last decade. First, the relationship between ownership or control concentration and profitability has changed over time. Second, the pay-for-performance relation is influenced by large shareholder control: in firms with controlling blockholders and when a universal bank is simultaneously an equity- and debtholder, the pay-for-performance relation is lower than in widely held firms or blockholder-controlled firms. Third, since 1995 several major regulatory initiatives (including voluntary codes) have increased transparency and accountability.  相似文献

和谐强调一种更高要求和层次上的配合,其意味着冲突的消弭,而国际私法以解决法律冲突为根本任务,其中的国际民事司法协助通过国际合作的方式体现了这一价值追求.和谐与国际私法是否存在联系?存在怎样的联系?其作为一种价值范畴对于国际私法是含是可欲的?带此疑问对国际私法中程序法领域的国际民事司法协助进行具体制度上的考量,以期获得一种对和谐与国际私法内在关系上的认识.  相似文献

Relatively little is known about when, why, and how some jurisdictions “double down” on policy priorities, rapidly adopting multiple measures tackling the same issue. Rapid policy expansion can emerge in fast‐evolving, uncertain, and contested policy arenas in which pressures for policy making are not satisfied, and even may be strengthened, by initial policy innovation. This article analyzes local government policy making on high‐volume hydraulic fracturing by New York State municipalities from 2008 to 2012. Policy path dependence, peer influence, and policy design appear to play a critical role in determining whether public officials respond to these pressures with policy expansion. Initial policy innovations can open windows for policy participants to secure additional measures that strengthen or enlarge the scope of action. Public officials and stakeholders seeking particular policy outcomes should take a long view of the policy process while simultaneously remaining alert for opportunities afforded by pressurized policy dilemmas.  相似文献

Climate science research documents and predicts changes in the physical environment. This information informs policy decisions and public programs through the design of human interventions that promote adaptive management. Since the early 2000s, federal funding has led to the creation of transdisciplinary regional climate workgroups to facilitate integrative knowledge coproduction and promote shared use of research results by scientific and nonscientific stakeholders. Labeled “boundary organizations,” these workgroups are tasked with facilitating partnerships between climate science researchers and practitioners with expertise in multiple physical and social science disciplines. When these organizations are successful, scientific findings and practitioner experiences are integrated to synergistically create usable knowledge about adaptive management that provides direct public value and creates broader societal impacts. This article explores the broader impacts provided by these boundary organizations through the establishment of regional research agendas and the communication of research results in ways that influence regional public policy and promote adaptive management.  相似文献
