中国共产党有效执政的基础、挑战及路径依赖

执政党的有效执政,最根本的是要有效地规范、利用和分配好自身的执政资源,这是提升其执政合法性的重要基础。在新时期,中国共产党要实现有效执政,虽有其一定的基础和源泉,但也面临着严重的挑战。整合好执政资源,是中国共产党实现有效执政的价值选择。     

统一战线与党的建设:建设中国特色社会主义的重要法宝

统一战线是中国共产党克敌制胜的法宝,是党的建设理论的重要组成部分.统一战线必须坚持党的领导,同时统一战线对加强党的思想、组织与作风建设具有着重要意义.文章指出,在党的统一战线理论中,统一战线已经成为国家制度、党和国家决策的重要环节,它已经不是一个简单的党的作风问题,而是制度建设的一个重要内容.     

试论我国资源物权立法的不足与完善

资源物权作为重要的财产权 ,要求自然资源法应以传统物权法为理论基础 ,根据自然资源所特有的经济属性和生态属性 ,构建我国的资源物权制度。本文从资源物权制度的体系化设计、自然资源所有权主体、资源物权的变动、不动产资源物权的登记制度等几个重要方面对我国现行资源物权制度进行了反思与探讨 ,并在传统物权理论的基础上 ,提出了对策方案。     

冷战后印度一新加坡关系透析

印度与新加坡在历史上有着密切的联系。在冷战时期由于深受两极格局的制约、双方外交政策取向差异之影响,双边关系发展缓慢。自冷战结束后,印度与新加坡的哉略联系明显增强,在政治、经济、安全等领域合作日益加深。经济利益的追求、安全战略的契合、对恐怖主义和海盗活动的关注成为印度和新加坡战略合作的主要因素。     

Identification of forensically important sarcophagid flies (Diptera: Sarcophagidae) in China, based on COI and 16S rDNA gene sequences

Insects attracted to cadavers may provide important indications of the postmortem interval (PMI). However, use of the flesh flies (Diptera: Sarcophagidae) for PMI estimation is limited as the species are often not morphologically distinct, especially as immatures. In this study, 23 forensically important flesh flies were collected from 13 locations in 10 Chinese provinces. Then, a 278-bp segment of the cytochrome oxidase subunits one (COI) gene and a 289-bp segment of the 16S rDNA gene of all specimens were successfully sequenced. Phylogenetic analysis of the sequenced segments showed that all sarcophagid specimens were properly assigned into four species (Boerttcherisca peregrina [Robineau-Desvoidy, 1830], Helicophagella melanura [Meigen, 1826], Parasarcophaga albiceps [Meigen, 1826], and Parasarcophaga dux [Thompson, 1869]) with relatively strong supporting values, thus indicating that the COI and 16S rDNA regions are suitable for identification of sarcophagid species. The difference between intraspecific threshold and interspecific divergence confirmed the potential of the two regions for sarcophagid species identification.     

Fabrication of compound nonwoven materials for soft body armor

The primary objective of body armor research is the development of low-cost, lightweight, wearable garments that effectively resist ballistic impact. This study introduces a material intended to reduce nonpenetration trauma by absorbing energy from ballistic impacts. Layers of web were made by low-melting point polyester (LMPET) on unaligned fibers of high-strength polyamide 6 (HSPA6). A compound nonwoven fabric was made by laying high-strength Vectran filaments between two layers of HSPA6-LMPET web. The new fabric underwent needle punching and thermal bonding to form a composite sandwich structure. The new fabric was subjected to a falling weight impact test and a ballistic impact test. The results indicated that the material with the new design reduced maximum indentation depth by 8%. Furthermore, soft body armor made from the material with the new design would cost less to produce and would weigh 22.5% less than conventional soft body armor.     

《未成年人社会调查报告》的证据法分析

《未成年人社会调查报告》具有相关性、专业性和科学性、应用性,属于专家证据。社会调查员应当出庭质证,接受双方当事人的询问。法官应当结合其它证据对《报告》的可信性进行审查,并综合全案对其证明力大小作出判断。     

论罪犯自我改造的主体性

罪犯的教育改造是双向互动的过程,监狱干警对罪犯所施加的强制性的教育改造内容,只是外部影响因素,罪犯自我改造的主观能动性,才是提高教育改造质量的关键.为此,在罪犯教育改造中,应确立罪犯的主体性地位,充分保护罪犯合法权益,以激励罪犯的自我改造.     

Free Fatty Acids Composition in Adipocere of the Kwäday Dän Ts’ìnchí Ancient Remains Found in a Glacier*

Abstract: Adipocere is a postmortem decomposition product consisting of mostly a mixture of free fatty acids (FFAs) that are formed because of the hydrolysis of triglycerides in adipose tissues. This article describes a simple and robust method for the extraction, identification, and quantification of FFA commonly found in adipocere using gas chromatography–mass spectrometry (GC/MS). This method was applied to analyze tissues from Kwäday Dän Ts’ìnchí, ancient remains discovered in a retreating glacier in the Tatshenshini‐Alsek Park, British Columbia, Canada in August 1999. The lyophilized tissues were grinded and extracted with hexane. The trimethylsilyl fatty acid derivatives were analyzed by GC/MS, and the relative abundances of myristic acid, palmitic acid, oleic acid, and stearic acid were determined. Milligram per gram levels of saturated fatty acids were found in the tissues of the ancient remains, while the levels of unsaturated fatty acids, such as palmitoleic acid, were found to be negligible. The results provided further evidence of the existence of adipocere found during forensic examination of the Kwäday Dän Ts’ìnchí ancient remains.     

常见嗜尸性甲虫及蝇类虫体不同部位mtDNA的提取效果

目的探讨改良后十六烷基三甲基溴化铵(cetyltriethylammnonium bromide,CTAB)法对常见嗜尸性昆虫虫体不同部位mtDNA的提取效果。方法随机采集放置在呼和浩特地区室外草地家兔尸体上丽蝇科的丝光绿蝇[Lucilia sericata(Meigen)]、埋葬甲科的Nicrophorus fossor(Erichson)各13例,采用改良CTAB法分别提取每只昆虫头部、胸肌、腿部、翅膀4个部位的mtDNA,核酸蛋白测定仪检测DNA纯度及质量浓度,琼脂糖凝胶电泳检测其PCR产物,测定PCR产物序列,上传GenBank。结果 13例丝光绿蝇[Lu-cilia sericata(Meigen)]的胸肌均提取到了DNA,10例头部样本、6例腿部样本、4例翅膀样本得到DNA;13例Nicrophorus fossor(Erichson)胸肌DNA均提取成功,5例头部样本、8例腿部样本及3例翅膀样本提取出DNA。结论改良CTAB法可用于对嗜尸性昆虫胸肌及其他部位进行DNA的提取。
