Identification of impurities and statistical classification of methamphetamine tablets (Ya-Ba) seized in Thailand

Impurity profiles of methamphetamine tablets seized in Thailand have been investigated. The samples are extracted with small amounts of ethyl acetate under alkaline condition and the extracts are analyzed by capillary gas chromatography. Nine compounds (1,2-dimethyl-3-phenylaziridine, ephedrine, methylephedrine, N-formylmethamphetamine, N-acetylmethamphetamine, N-formylephedrine, N-acetylephedrine, N,O-diacetylephedrie, methamphetamine dimer) are identified as impurities in methamphetamine tablet. Caffeine and ethyl vanillin are also detected as diluents and/or adulterants, and acetylcodeine monoacetylmorphine and diacetylmorphine are contained in many samples. In addition, trans-3,4-dimethyl-5-phenyl-2-oxazolidone is newly found as an impurity. For characterization and comparison of methamphetamine tablet exhibits, intensely and commonly detectable nine peaks are selected as the factor for multivariate analysis. The procedures reported here permit classification of 250 analyzed exhibits into five groups and characterization of classified groups.     

Genetic diversity at two pentanucleotide STR and thirteen tetranucleotide STR loci by multiplex PCR in four predominant population groups of central India

Genetic diversity study at STR loci in 208 individuals belonging to two backward groups, one caste and one tribal community of Central India called "Chhattisgarh" has been carried out to evaluate significance of Powerplex System loci in human identification and population diversity. Populations are Agharia (72), Satmani (50), Dheria Gond (36) and Teli (50). Fifteen loci (Powerplex 16 Kit) studied are Penta E, D18S51, D21S11, THO1, D3S1358, FGA, TPOX, D8S1179, vWA, Amelogenin, Penta D, CSF1PO, D16S539, D7S820, D13S317 and D5S818. The studied penta nucleotide STR (two) and 13 tetranucleotide (CODIS ) STR are found to be highly polymorphic genetic markers in all studied populations. Most common allele for the four studied population has been found to be same at THO1 (allele 9), D8S1179 (allele 14), CSF1PO (allele 12), Penta E (allele 11) and D16S539 (allele 11). Penta E is found to be most polymorphic (PD=0.89373) among studied 15 STR loci in four populations of Central India.     

中国的后李斯特主义崛起

虽然对于中国崛起已经有很多讨论,但是对中国崛起的含义仍有争议。争论的关键在于中国崛起是对全球范围的新自由主义霸权的挑战还是进一步巩固了全球范围的新自由主义霸权。本文批判地考察了激进全球化理论的一些关键假设,具体来说,就是中国代表着另一种形式的"竞争型国家",其发展抱负已经从根本上受到全球"新     

青少年刑事司法视野中的英国骚乱处置研究——以2011年8月伦敦骚乱处置为分析对象

2011年8月,伦敦北部托特纳姆区暴发大规模骚乱,并席卷伦敦和整个英格兰地区的多个大城市.青少年是暴乱的主要参与者,并乘着社会秩序的混乱,大肆打砸抢,造成了大量的人身和财产上的损害.在本案后续的刑事司法处置过程中,法院侧重于考察青少年群体性暴力整体、罪行恶性程度、社会和谐秩序受损程度,而不应该过多虑及暴乱参与者的原始动机.这种司法处置策略与英格兰地区长期以来处理大型暴乱的一贯刑事审判方针是一脉相承的.这对我国处理2012年10月中日钓鱼岛事件引发的打砸抢等影响社会安全的突发事件——尤其是对于当前尚未进行的刑事审判活动——具有积极的参考意义.     

中国崛起与亚太各国(地区)的反应:软平衡与融合

美刊《当代中国》(Journal of Contemporary China)2012年1月号刊登了澳大利亚墨尔本大学社会与政治学院副教授徳里克·麦克道高尔(Derek McDougall)的论文,原文标题为《中国崛起与东亚地区各国的反应:软平衡与融合》。这里的东亚是一个广义的概念,泛指整个亚太地区。     

A novel method for the identification of saliva by detecting oral streptococci using PCR

We have used DNA amplification methods to detect common oral bacterial strains to test for the presence of saliva in forensic samples. Streptococcus salivarius and Streptococcus mutans were detected in various forms of saliva samples, whereas these streptococci were not detected in semen, urine, vaginal fluid, or on skin surfaces. Therefore, we demonstrated that these streptococci are promising new marker for the forensic identification of saliva. Our data indicated that S. salivarius is more reliable than S. mutans as an indicator of saliva presence, because the detection rates for S. salivarius and S. mutans by this method were 100% and 90%, respectively. Furthermore, S. salivarius was detected in all saliva stain samples, whereas S. mutans was only identified in 60% of the stains. Finally, using this method we were able to successfully detect S. salivarius and S. mutans in mock forensic samples. We therefore suggested that this method is useful for the identification of saliva in forensic science.     

Unemployment among women: examining the relationship of physical and psychological intimate partner violence and posttraumatic stress disorder

Prior research has demonstrated that intimate partner violence (IPV) is associated with employment instability among poor women. The current study assesses the broader relationship between IPV and women's workforce participation in a population-based sample of 6,698 California women. We examined past-year IPV by analyzing specific effects of physical violence, psychological violence, and posttraumatic stress disorder (PTSD) symptoms as predictors of unemployment. Results indicated substantial rates of unemployment among women who reported IPV, with rates of 20% among women who experienced psychological violence, 18% among women who experienced physical violence, and 19% among women with PTSD symptoms. When the relationship was adjusted for demographic characteristics and educational attainment, PTSD (adjusted odds ratio [AOR] = 1.60; 95% confidence interval [CI] = 1.22, 2.09) and psychological violence (AOR = 1.78; 95% CI = 1.36, 2.32), but not physical violence, were associated with unemployment. Implications for supported employment programs and workplace responses to IPV are discussed.     

美国管制革新的方法

美国<行政程序法>,总的来说是一件相当不错的法律,很好地经受住了时间的考验.当然,我们也承认它存在一些缺陷,并需要更新,但是反对商业团体和他们在国会中的支持者们所提出的这样巨大的、有时甚至是激进的改变.
