A case of fatal aconitine poisoning by Monkshood ingestion 总被引:2,自引:0,他引:2
Accidental aconitine poisoning is extremely rare in North America. This report describes the confirmation of a case of accidental aconitine poisoning using a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. The case involved a 25-year-old man who died suddenly following a recreational outing with friends where he consumed a number of wild berries and plants including one that was later identified as Monkshood (Aconitum napellus). Postmortem blood and urine samples were available for analysis. All routine urine and blood toxicology screens were negative. The LC-MS/MS method allowed sensitive quantification of aconitine, the main toxin in A. napellus, and showed 3.6 and 149 microg/L in blood and urine, respectively. These concentrations were similar to that reported in other aconitine-related deaths. This case illustrates the dangers of consuming unidentified plants, and documents concentrations of aconitine in blood and urine in a fatal case of A. napallus-related poisoning. 相似文献

日本反垄断法实施中的竞争政策和产业政策 总被引:1,自引:0,他引:1
日本反垄断法在过去的60年间经历了一个曲折的发展过程.现在,反垄断法越来越受到日本政府的重视,被称为是经济法中的基本法.日本反垄断法在实施中体现了竞争政策和产业政策的对立和统一,在实践中积累了丰富的经验.现在,追求两者的协调发展是日本反垄断当局和部门主管机关的共同执法目标.我国刚刚颁布实施的反垄断法也将追求竞争政策和产业政策的协调发展作为指导原则,分析研究日本反垄断法的实施经验对于我国有重要的借鉴意义. 相似文献

AbstractThis essay, introducing the special issue on ‘Borders of Memory’, aims to shed light on the links between memory and heritage in contemporary Japan. It does so by examining how heritage sites serve as spaces within which collective memory is both affirmed and contested. Heritage sites enable us to survey the contours of the borders of memory that exist between different memory collectives. An analysis of South Korean and Chinese objections to the Meiji Industrial Sites shows how these heritage sites work as borders of memory, spaces where the competing collective memories of neighbouring East Asian governments and societies clash and rub up against one another. This analysis is then extended to the four articles that make up this special issue. In each case, it is the competing meanings invested in the site, and the struggle over the narrative within which it is incorporated, that results in such sites coming to be demarcated as borders of memory. Understanding these heritage sites as bordered spaces allows us to see such them as being not only where antagonistic collective memories come into contact, but also spaces through which they connect. The existence of such spaces enables the political process of articulating the stories associated with different memory collectives. 相似文献

With drug-related violence reaching record levels in Mexico, there has been growing debate over its causes. US and Mexican officials blame many factors, including problems with their strategy in the drug war, fighting among cartels, corruption in police forces, an ineffective legal justice system and US drug demand. In this paper, I argue that the Mérida Initiative, a multi-billion dollar programme of US assistance, is an important additional factor. Drug-related violence increased in the years after the implementation of the Mérida Initiative, declined when Mexican officials paused new programmes in 2012 and increased again as US and Mexican officials implemented new Mérida programmes in the following years. Over the same time period, drug-related homicides and complementary counternarcotics assistance from the US Department of Defense are positively correlated. Using US records, I show that US officials have been willing to overlook the growing violence because they have been more focused on achieving their economic and strategic objectives. I conclude that their actions have played a significant role in increasing drug-related violence while starting an ominous new phase of US imperialism in Mexico. 相似文献

To understand how time and temperature could affect latent fingerprints, wooden pallets were used to construct five units that each housed ten 60-watt incandescent light bulbs. Fingerprints were deposited on the top, middle, and base of the globes. The bulbs were powered on (except the control bulb in each unit) for 18, 48, 72, 120, 168, 336, 504, and 672 h. Fingerprints recovered from the bulbs by tape lift after black powder processing were given a quality score. A thermal imaging camera determined temperatures on three areas of the bulbs. Fingerprints on the top of the globe (156.3°C) had the lowest quality score, and fingerprints on the middle of the globe (112.6°C) had the highest quality score. The mean quality scores of the three temperature classes were within one standard deviation of one another, meaning there is no way to estimate fingerprint age based on its quality after heat exposure. 相似文献

Civil servants are perceived to possess altruistic motive known as Civil Service Motivation (PSM) which promotes public interest as confirmed in some developed countries. Using the Ejisu-Juabeng Municipality as a case study, this article assesses the existence of PSM in the Ghanaian public sector and finds that PSM exists in the public service but its existence does not ensure maximum output. The workers professed having motives such as sense of social justice, compassion, commitment to public interest, self-sacrifice, and sense of civic duty but indicated their unwillingness to commit their future to the public sector because of poor working conditions. 相似文献

Juveniles who have committed sexual offenses are subject to specialized treatment and policies based on their assumed unique dangerousness, despite contradictory evidence. Limited information is available regarding risk factors and their relationships to outcomes in this population. The comparative frequency and predictive utility of empirically supported risk factors for general delinquency were examined using data from the Pathways to Desistance study. Adolescent males who committed sexual offenses (n = 127) were compared to adolescent males who committed non-sexual offenses (n = 1021). At the start of the study, the sample ranged in age from 14 to 18 (M = 16.00, SD = 1.12) and self-identified as primarily African American (44 %), Latino (29 %), or White (25 %). Outcomes were measured over 7 years and included general and sexual recidivism, involvement in school and work, and positive relationships with peers and adults. The results indicated a few small differences in the presence of risk factors and their relationship to outcomes, with many similarities. Juveniles who have committed sexual offenses had equivalent general recidivism but higher sexual recidivism, though this rate was low (7.87 %, or 10 of the 127 adolescents who had committed sexual offenses). New clinical and policy approaches may be needed given the similarities between groups. 相似文献

The relationship between victimization and offending has been shown consistently across different samples, settings, and crime types. This study uses data from the Pathways to Desistance Study to examine dual trajectories of offending between the ages of 15 and 24 in a sample of male felony offenders. The dual trajectory models demonstrate substantial convergence in victimization and offending. And while there are sizable numbers of youth who continue to be victimized, but desist or decrease in their offending behaviors, very few youth continue to offend in the absence of continued victimization. This study also proposes and tests three criminological theories that have been employed as explanations for the victim-offender overlap—low self-control, lifestyles/routine activities, and street-code attitudes. The logistic regression results indicate that involvement in risky and/or unstructured, unsupervised activities is a key correlate of the victim-offender overlap. The strength of the relationship between routine activity variables and the victim-offender overlap supports the provision of structured, supervised activities for youth and young adults as a way of preventing future victimization and offending, particularly among youth who have high exposure to violence. 相似文献
