警民互动的理论基础研究

当前我国正在全面实施社区警务战略,其核心内容就是通过警民之间的互动,充分利用社区资源凝聚社区的向心力,从而解决社区中的治安问题。但不管在理论界还是在实战部门,对警民互动的理论缺乏研究。本文提出了警民互动的四个理论基础：社会契约论(Thesocialcontract)、变革管理理论(ManagingChange)、破窗理论(BrokenWindowTheory)和社会控制理论(SocialContrloTheory)。     

论澳洲当代小说创作的多元化

澳洲文化在世界上独树一帜,具有多元化的特征,作为其中重要组成部分的小说也是如此.本文从创作流派、题材和方法的新角度,详尽论述了澳洲当代小说创作的多元化风格,并对这种风格形成的社会背景及原因进行了深入剖析,指出这种多元化正是澳洲的历史发展过程的折射.     

全球产业结构调整背景下俄罗斯经济定位的困境

俄罗斯的市场化改革经历了漫长的痛苦历程。1999年以来,在良好的国际市场行情下,俄罗斯经济取得了较快的恢复性增长。本文立足于全球化背景下的产业结构升级和转移的历史趋势,结合当前世界产业结构调整的时代特征,从国际分工格局和俄罗斯国内经济总供求的角度,分析俄罗斯经济由于内在的结构性因素导致其在世界经济体系中定位的困境,认为其发展前景仍不容乐观。     

浅谈中国加入《东南亚友好合作条约》对亚太安全的影响

今年10月6日,在印尼巴厘岛举行的中国与东盟10+1峰会上,中国正式加入《东南亚友好合作条约》。这一重要事件不仅标志着中国与东盟关系进入了一个新的发展阶段,而且将对亚太安全产生重要影响。其影响主要体现在:有利于中国与东盟国家和平解决争端,共同承担起维护亚太地区安全的责任;推动预防外交的开展,有利于在亚太地区建立冲突预防机制;促使亚太地区大国调整安全关系,更加强调相互依赖与合作;推动亚太安全合作朝合作安全的方向发展。     

运用二重PCR和DNA芯片技术检测ABO基因型

目的以玻片为载体,用寡核苷酸探针杂交技术检测ABO基因型。方法根据ABO基因座外显子6和外显子7的3个SNP点的序列分布特征设计4条寡核苷酸探针,制成分型芯片。将待测样品DNA用末端标记了Cy5的引物进行二重PCR扩增,产物与芯片上的探针进行杂交,根据杂交产生的荧光信号确定样品的ABO基因型。结果利用ABO芯片,可对血斑、毛发等微量检材进行ABO基因型检测。对115名汉族无关个体的调查表明,ABO基因型的分布符合Hardy-Weinberg平衡,等位基因杂合度观察值和期望值分别为0.591、0.616,多态信息含量为0.544,二联体和三联体非父排除率分别为0.188、0.334,个体识别能力为0.777。结论通过DNA芯片检测ABO基因型的技术适用于法医学样本,可满足高通量的检测需求。

Rapid determination of ketamine in urine by liquid chromatography-tandem mass spectrometry for a high throughput laboratory

In recent years, the abuse of ketamine had gained popularity in rave parties in Hong Kong. The Urinalysis Unit of the Government Laboratory of Hong Kong faced a tremendous increase in workload for ketamine analysis. The number of tests performed rose from 10 in 1999 to 15,000 in 2002. As a fully validated immunoassay test for ketamine was not available in the market, most laboratories analyzed ketamine by chromatographic techniques after liquid-liquid extraction. However, these methods reported in the literature are not suitable for high throughput laboratories. Hence, a rapid screening/confirmation method for ketamine by liquid chromatography-tandem mass spectrometry (LC-MS-MS) with a detection limit of 5 ng/ml was developed. After automated solid-phase extraction (SPE), the urine extract was analyzed for ketamine by a 2.5-min chromatographic run, the estimated recovery was 89% and the precision was 11% R.S.D. at 20 ng/ml. With the aid of an in-house developed computer program, the results were presented in spreadsheet format for easy checking. The method has been applied to our laboratory for routine ketamine analysis and a maximum of 200 samples per day can be achieved.     

Patterns and Dynamics of China's International Strategic Behaviour

The acceptance and promotion of partnerships among major countries reflect an attempt on the part of China to re-define its position in the new international strategic pattern. They also reveal a strategic idea offered by China in the post-Cold War era in which it is emerging as a major power. The key questions are as follows. (a) What are the contents of such partnerships among major powers? (b) What are the differences between this partnership model among major powers and the Chinese foreign policy of independence and peace in the 1980s? (c) What are the motivations behind China's promotion of this model of partnerships among major powers? (d) Does the new model of partnerships among the major powers provide an important innovation in the management of relations among the major powers in the coming century? This article attempts to answer these questions so as to better understand China's international strategic behaviour patterns in the post-Cold War era, the inner logic of partnership relationships, and the trends of China's international strategy in the coming century.
