农村社区警务建设存在的问题及对策分析

农村社区警务的实施对于建设社会主义新农村,保证全社会的安定有序有着重要的意义。但现在农村社区警务存在着很多问题：一是部分民警对社区警务工作重视不够：二是公安机关用于农村社区警务的经费和警力保障不足;三是警民关系不够和谐,农村社区警务工作没有形成警民合力。因此,农村社区警务建设的重点是：一、完善法律法规;二、警力资源的科学配置;三、民警素质的有效增强。     

行政许可程序的立法欠缺及其完善

行政许可程序是规范行政许可的行为,防止行政许可实施权的滥用,保障公民、组织在行政许可实施中的正当权利的重要环节。尽管行政许可法设计了许多程序规则,但在某些方面还存在问题,诸如处理期限的规定不完善、听证程序不健全、缺乏有效的保障制度等。笔者在对此分析研究的基础上,提出了一些健全和完善我国行政许可程序的设想和建议。     

对实用艺术作品著作权保护之法律探析——完善我国《著作权法》立法建议

我国《著作权法》及《著作权法实施条例》中,对实用艺术作品均没有任何明确的规定,实用艺术作品的法律保护至今仍为空白。我国应结合国际公约、条约和国外一些国家的法律规定,在《著作权法》中应明确规定对实用艺术作品的著作权保护的具体措施。     

人民民主专政理论的哲学分析及当代启示

人民民主专政理论是毛泽东思想的重要组成部分,包含着丰富的哲学思想。关于这一理论的哲学分析,对当前中国特色社会主义建设的启示是:党必须推动中国经济社会的全面发展,必须始终把发展作为党执政兴国的第一要务,必须始终坚持以人为本的执政理念,必须用发展着的马克思主义指导中国新的实践。     

师专学生心理健康状况的调查分析及对策

对1986名师范专科学校的新生的心理健康状况调查表明,有12.34%的学生存在不同程度的心理症状和心理问题,有50.14%的学生存在人际关系不协调、新环境不适应等问题。造成大学生心理健康状况欠佳的原因是多方面的,学校有必要进一步加强学生的心理卫生教育。     

美国反垄断法中界定“相关市场”的临界损失分析法

美国早期用来界定"相关市场"的方法没有限定市场弹性幅度,这个缺陷直到"假定的垄断者测试"产生后才得到弥补。1986年,美国改进了"假定的垄断者测试"操作方法,提出了临界损失分析法。虽然人们对临界损失分析法还存在不少争议,但它在美国和欧盟得到了越来越广泛的应用,相关判例得到了极大的丰富。     

Science Parks’ tenants versus out-of-Park firms: who innovates more? A duration model

We study the successfulness of Science Parks (SPs) as seedbeds of innovation. We investigate whether SPs enhance the innovative output of their tenants and if tenants outperform comparable outside-SPs firms. We rely on original matching datasets regarding in- and out-SP Finnish firms and their patenting activity over 1970–2002. We estimate and compare the ‘before-versus-after’ hazard rates of patenting of both samples. The results suggest that, given the existence of a common tendency to slow down the pace at which all firms patent during their life cycle, Park tenants exhibit a comparatively better performance. Results are robust to various model specifications and to Wald tests performed over the pooled samples.

Identification of acepromazine in hair: an illustration of the difficulties encountered in investigating drug-facilitated crimes

After a drug-facilitated sexual assault (DFSA), a woman was found in a drowsy state at home. She remembered having drunk an unknown beverage by the accused. Blood samples (collected 8 hours after the DFSA), two glasses, and a teaspoon seized by the police were analyzed. Acepromazine, a phenothiazine tranquilizer used in human and veterinary medicine, was detected in the residue of one of the glasses. In spite of acepromazine absence in the victim's blood, the possible use of acepromazine in the DFSA was reported to the police. Two weeks later, a suspect admitted having orally administered acepromazine to the victim. Using a liquid chromatography-tandem mass spectrometry method, this compound was subsequently detected (31 pg/mg) in a sample of the victim's hair collected a month and a half after the DFSA. A potential short elimination half-life in humans and/or the well-known in vitro degradation of acepromazine could explain the negative blood result. DFSA toxicological investigations are challenging and can be complicated when a rather unusual substance is concerned. In particular, special care should be taken when interpreting the results, taking into account elimination and/or instability data, when available.     

Classification and individualization of black ballpoint pen inks using principal component analysis of UV-vis absorption spectra

The technique of principal component analysis has been applied to the UV-vis spectra of inks obtained from a wide range of black ballpoint pens available in the UK market. Both the pen ink and material extracted from the ink line on paper have been examined. Here, principal component analysis characterised each spectrum within a group through the numerical loadings attached to the first few principal components. Analysis of the spectra from multiple measurements on the same brand of pen showed excellent reproducibility and clear discrimination between inks that was supported by statistical analysis. Indeed it was possible to discriminate between the pen ink and the ink line from all brands examined in this way, suggesting that the solvent extraction process may have an influence on these results. For the complete set of 25 pens, interpretation of the loadings for the first few principal components showed that both the pen inks and the extracted ink lines may be classified in an objective manner and in agreement with the results of parallel thin layer chromatography studies. Within each class almost all inks could be individualised. Further work has shown that principal component analysis may be used to identify a particular ink from a database of reference UV-vis spectra and a strategy for developing this approach is suggested.
