A novel method for the analysis of discharged smokeless powder residues

A novel method for the estimation of intermediate-long firing distance range is proposed. The method is based on the characterization and chemical analysis of the smokeless powder particles on the target. An adhesive lifter is applied to collect the suspected gunshot residues (GSRs) from the surface of an object, and a Modified Griess Test (MGT) is carried out after alkaline hydrolysis on the adhesive lifter. Visualized particles are removed from the adhesive lifter under a microscope. Two systems are used for the analysis of organic discharge residues from the smokeless powder: (1) gas chromatography/thermal energy analysis (GC/TEA) for the analysis of nitroglycerine (NG) and 2,4-dinitrotoluene (2,4-DNT), (2) gas chromatography/mass spectrometry (GC/MS) for the identification of organic components such as DNT, NG, and some stabilizers. By using this procedure and confirming that the suspected particles are indeed GSR, one can estimate the intermediate-long firing distance of c. 0.75-3 m in the presence of very few particles and provide information for the classification of ammunition type in casework.     

后危机时代的中国经济安全问题

后危机时代中国经济安全受到严峻挑战。经济安全主要包括金融安全、产业与贸易安全、战略资源安全和信息安全。在金融安全方面,金融监管体制的相对滞后,金融开放和金融全球化程度的提高对我国金融安全构成直接或间接的威胁。而产业与贸易安全方面,外商直接投资对我国产业发展带来一定冲击,较高的外贸依存度降低了我国经济抵御外部风险的能力。战略资源安全主要集中在石油安全和粮食安全上。我国的信息安全也面临着巨大的挑战。要使我国经济安全得到保障,应尽快培育和树立经济安全意识,制定国家经济安全整体战略;要建立经济安全的预警防范机制和风险释放机制;要把握对外开放的主动权积极参与多边合作。     

我国洗钱犯罪现状分析

每种犯罪，在行为的最后似乎都要有个买单者才能表现出犯罪周期循环结束，那么在很多情况下．洗钱就顺理成章地成为众多犯罪交易的一个必要步骤，担负着资金回流的“重任”。从洗钱存在及衍变的趋势分析出发，分析洗钱犯罪在我国的现状，从而为从根本上认识洗钱犯罪的全貌打下基础。     

新时期我国社会纠纷问题探析

新时期我国社会纠纷呈现增多趋势,这些纠纷是伴随着社会利益调整、结构调整和社会秩序重建而产生的,也缘于这些调整与改革还不到位。要解决这些问题,必须以科学发展观为指导,树立正确的执政理念,遵循法治精神,才能有效化解社会纠纷。     

论我国行政诉讼被告确认标准的重建

一般认为,目前我国行政诉讼被告资格的确认以行政主体为标准,这一规则给行政诉讼法的实施带来了不利影响。以行使权力时的行为是否为行政行为为标准,以保护公民、法人和其他组织的合法权益为目标,则非行政组织、行政机关的内部组织、行政人等都可成为行政诉讼被告。相应组织除了承担力所能及的责任外,行政诉讼后果则转继到行政诉讼被告所归属的行政机关或行政组织,由国家来承担赔偿责任。     

检察机关实施刑事被害人国家补偿的正当性

我国目前在刑事被害人国家补偿实施机构的选择上,主要有法院主导、专门机构主导、检察机关主导、司法行政机关主导、民政机关主导、多机关共同主导等六种模式.上述六种模式各有自身的优劣,但相对而言,检察机关主导模式有较多的优点,其可能出现的问题也是可控的.因此.我国以检察机关作为刑事被害人国家补偿机构是较好的选择.     

论新闻评论的准确性和说理性

作为报纸重要内容的新闻评论写作中有两个至关重要的问题--准确性和说理性.准确性中包括命题准确、由头准确、分寸准确、分析准确、政策准确五个方面.说理性应该具备思想深刻、虚实结合、善用对比、巧用矛盾、力戒片面、政策界限清楚、精心提炼语言七个方面.     

浅论企业折旧的税务筹划

现行会计制度和税法赋予企业固定资产折旧方法和折旧年限的选择权,企业可以通过折旧费用影响利润并最终影响所得税额,因此具有较大的税务筹划空间。企业若能利用折旧方法的合理选择和折旧年限的合理确定来开展税务筹划,必能使企业合法地减轻税负,增加税后收益。     

Characteristics of the ＂Islamic State＂

The extreme organization that calls itself the ＂Islamic State＂ has alarmed the world with its rapid rise and grave damage while drawing sharp censure from numerous directions. In his speech on the strategy of dismantling the ＂Islamic State of Iraq and Syria,＂ American President Barak Obama＇ s called it ＂a terrorist organization, pure and simple.＂ 1 Rooted in Middle East turmoil, facilitated by the irresponsible policies of the great powers and nearby countries, the ＂Islamic State＂ （also known as ISIS or ISIL） stands out from among regional terrorist organizations in a number of vital characteristics. ISIS, disowned by the A1-Qaeda, nevertheless challenges it and seems to gain the upper hand. What lies behind its success are at least two powerful characteristics： its religio-political ambition to establish a recognizable country, and its ability to entice the zeal of Western jihadists.
