A rapid gas chromatographic method for the fingerprinting of illicit cocaine samples.

A gas chromatographic (GC) fingerprint method, based on the presence or absence of six congeners, was developed for illicit cocaine samples. The fingerprint utilizes the relative abundances of these congeners towards each other, disregarding cocaine as the main constituent, and can be expressed numerically or graphically in the form of pictograms for rapid visual comparison. The method can be applied directly to a solution of the sample in chloroform, without previous workup procedures. More than 70 unrelated samples were analyzed and a great variation was observed in the parameter composition. On the other hand, a remarkable similarity could be seen between related samples. The GC fingerprint method may be considered an important contribution for sample comparison, as is exemplified by a subdivision of the analyzed samples in different categories, based on the number and types of congeners found.     

Measuring carbon monoxide content in muscles

A method ist described to determine the CO-content in the tissue of muscles. The prepared tissue is pulverized in a swinging mill at the temperature of liquid nitrogen. Parts of the powder are weighed into headspace vessels. Carbon monoxide ist ejected by a formerly described method and measured gaschromatographically. The Fe-content is determined after an acid disintegration by AAS. Acute intoxications lead to higher CO-contents in heart than in periphere muscles. Chronic exposure to carbon monoxide does not produce these differences.     

"城市经营"与时俱进之我见

城市经营作为中国城市建设与发展新的实践模式，过去几年是功绩与缺陷并存．作为一种新的城市发展理念，给我们以众多的思想启迪。随着人类进入21世纪和我国全面建设小康社会的推进，城市经营的基本要素在实践中应与时俱进地更新；其理论体系也不宜以企业经营和市场营销的基本理论、思想方法的“放大转换”为架构，而应百花齐放地去研究与创新。     

中国共产党党内民主发展的难点辨析

考察中国共产党党内民主发展的历史与现状,党内民主的发展其难点主要在于:组织文化传统的制约、理论期待与实践的落差、发展战略的模糊、民主集中制的缺陷、实体民主与程序民主的脱节、发展动力的匮乏。     

Child's play: The political imaginary of international relations and contemporary popular children's films

Many scholars in International Relations (IR) have drawn from popular films to examine various problématiques that have informed the discipline's main theorisations. As Cynthia Weber remarks, popular films are powerful because they engage in the very ‘serious political work’ of mythologising the ‘truths’ and ‘realities’ which provide the foundation for many of IR's main theoretical envisionings of our world. To date, however, children's films have received very little attention. For the purpose of this paper, three have been isolated: Toy Story (1995), A Bug's Life (1998) and Rescue Heroes: The Movie (2003). Children's films, it can be argued, help to craft and restore certain perspectives for each new generation of young minds during the crucial years when the world is being textualised for the first time. The objective of this paper, therefore, is to read these films as working towards producing and sustaining the power/knowledge that seeks to defend contemporary forms of world order while concurrently extending and disseminating the rule of these forms of world order through the medium of children's popular cinema.     

浅论我国刑事陪审制度的规范化

刑事陪审制度是一项古老的司法制度 ,在人类的司法文明史上影响深远。中国的刑事陪审制度经过两起两落的坎坷历程 ,处于一种进退两难、操作混乱的状态。在结合我国的具体国情和吸收国外有益经验的基础上 ,提出了完善刑事陪审制度的具体措施。     

哈萨克斯坦独立以来的人口与人口迁移

年轻的哈萨克斯坦共和国独立以后面临着十分严重的人口危机,其主要表现为主体民族在全国总人口中所占比重不到一半;大量居民因各种原因迁离哈萨克斯坦;人口出生率下降,死亡率上升.面对这种情况,政府采取了一系列措施,如鼓励国外的哈萨克人迁回哈萨克斯坦居住;采取积极的人口生育政策,提高本国公民、特别是哈萨克族居民人口出生率;推行民族和睦政策,等等.同10年前相比,哈萨克斯坦的人口状况与结构已经发生了较大变化.     

中国的崛起与东亚合作

东亚合作更多地表现为一种地区多边合作的过程。作为东亚的一个成员,和平发展的中国无疑是东亚区域合作最重要的动力源之一。从地缘上看,美国不属于东亚范畴。但基于历史原因和美国独特的地位,东亚合作进程又不可能排除美国的影响,甚至需要美国建设性的参与。因此,东亚合作一方面是一个内部一体化的过程,另一方面也涉及到一个对外部开放的问题。如何评估东亚合作进程中的中国的作用、美国对东亚合作进程的影响以及东亚合作背景下中美关系的前景等已经成为学界研究的一个热点。为此,中国国际关系学会、外交学院、美国乔治.华盛顿大学联合举办了“东亚地区合作与中美关系”国际研讨会(2005年11月),中美双方学者就此展开坦诚的对话交流。在会议讨论的基础上,我刊以笔谈形式整理刊发部分学者的观点,以飨读者。
