A method using liquid chromatography–tandem mass spectrometry (LC–MS/MS) to simultaneously quantify amphetamines, opiates, ketamine, cocaine, and metabolites in human hair is described. Hair samples (50 mg) were extracted with methanol utilizing cryogenic grinding. Calibration curves for all the analytes were established in the concentration range 0.05–10 ng/mg. The recoveries were above 72%, except for AMP at the limit of quantification (LOQ), which was 48%. The accuracies were within ±20% at the LOQ (0.05 ng/mg) and between −11% and 13.3% at 0.3 and 9.5 ng/mg, respectively. The intraday and interday precisions were within 19.6% and 19.8%, respectively. A proficiency test was applied to the validated method with z-scores within ±2, demonstrating the accuracy of the method for the determination of drugs of abuse in the hair of individuals suspected of abusing drugs. The hair concentration ranges, means, and medians are summarized for abused drugs in 158 authentic cases. 相似文献

关于提高女性劳动者退休年龄的探讨 总被引:2,自引:0,他引:2
关于提高中国退休年龄问题,近来引发了社会各界的广泛关注。文章深入分析了广泛关注的几个因素:平均余命变化,世界的退休年龄变化趋势以及对于劳动力市场的影响,并进一步分析了当前制度规定下女性退休年龄偏低产生的低收益及退而不休现象及其影响。在此基础上,文章建议:中国应当提高女性退休年龄;结合劳动力人口变化趋势,采用小步渐进的方式进行调整。好处在于:在一定程度上解决女性退休后低收益问题,因而可以缓解退而不休现象;在一定程度上优化劳动力市场供给。 相似文献

青少年生命意识淡漠的原因分析 总被引:1,自引:0,他引:1
近年来,青少年残害他人生命自杀现象日益突出。青少年生命意识较为淡漠与青少年没有形成良好的生命意识,既有其自身的心理、生理等原因,又与教育、制度以及舆论引导等三个方面的缺失有着极大的关联。 相似文献

The purpose of this study was to examine the relationships among Chinese American adolescents’ discrimination experiences,
cultural orientations, and delinquent behaviors. Data were collected from three hundred and eleven Chinese American adolescents
(58% girls) and their parents when the adolescents were 7th or 8th graders and again 4 years later. The data analyses demonstrated
that adolescents’ perceptions of discrimination and victimization experiences were significantly related to their delinquent
behaviors conditionally based upon their cultural orientation. Specifically, adolescents’ high Chinese cultural orientation
amplified the negative impact of discriminatory experiences on delinquent behaviors whereas high Western cultural orientation
protected them against that impact. The significance of both ethnic and mainstream cultural orientations for understanding
ethnic minority adolescents’ adjustment and improving their adjustment outcomes is discussed. 相似文献

This article examines how media framed the deadly stampede that killed several dozen people gathered to celebrate a festival in Ethiopia. News articles published by 14 national media (N=21) and 116 international media (N=117) on October 2 and 3, 2016 were collected and comparative content analysis was carried out between April and May 2017. Conflict, attribution of responsibility and political consequences frames dominated the coverage. The differences observed in the use of conflict, responsibility and morality frames by national and international media were statistically significant. The differences in the appearance of political consequences and human-interest frames in national and international media were not statistically significant. In terms of coverage pattern, the themes of headlines of almost all the news articles published on the first day after the incident focused on deaths of people whereas the second day headlines diverged to deaths, mourning, unrest that followed, and other issues as the media found additional facts to organise strong and compelling frames to influence the audience. Based on the findings, this article generalises that national and international media cover the same disaster from different perspectives—national media promote national interest whereas international media emphasise conflict. 相似文献
