从团队建设看北京奥运志愿者的有效管理

奥运会是当今世界最盛大的社会文化现象,在其中扮演着重要角色的志愿者是奥林匹克运动的基石,是奥运会真正的形象大使.但在实际工作中,由于管理制度的不完善,使得志愿者在服务过程中出现了很多遗憾.在北京2008年奥运志愿者培训与管理工作中,团队组织构建具有重要的意义,能够加强志愿者之间的沟通,开展朋辈教育,完善激励和保留机制,促进志愿服务质量的提高.     

公诉环节风险评估预警机制的科学构建

公诉环节风险评估预警机制对于化解社会矛盾、维护稳定、促进和谐具有重要意义。公诉环节风险评估机制具有容纳冲突、预测风险等内在价值,通过明确和规范其适用程序、责任追究机制及完善内处部门协调联动机制、加强释法说理等工作可以构建科学、合理的公诉环节风险评估预警机制。     

吉林省农民增收问题实证研究——基于人力资源开发视角的思考

农民增收问题是"三农"问题的关键。有分析表明,吉林省农民收入中工资性收入和家庭经营二、三产业收入比重较低,因而着力提高农民的非农产业收入势在必行。农民素质的提高对其非农就业和非农收入增长具有显著的促进作用,为此,应大力开发农村人力资源,切实提高农村人力资本质量,以增强内生变量对农民增收的作用,从而形成农民增收的长效机制。     

论独立监管机构的经济法主体地位——以马克思主义社会权力机构学说为视角

早在19世纪中叶,马克思、恩格斯就已经预见到社会权力机构的兴起,这一预见已被中西方主要国家独立监管机构的产生与发展实践所证明。作为日益重要的经济管理主体,独立监管机构的公益代表性与权力合一性完全契合经济法主体特征的基本要求,亟需在经济法主体理论上对此作出回应。纳入独立监管机构考量后的经济法主体理论更加完善,可以明晰国家与政府在经济法主体类型上的差别,解释政府作为经济法主体和行政法主体在性质上的不同,并在一定程度上回答了社会中间层的经济法主体地位问题。基于独立监管机构的发展现状与趋势,经济法主体将呈现出"政府——独立监管机构——市场主体"互动模式。     

A 21‐Locus Autosomal SNP Multiplex and its Application in Forensic Science

To develop a cost‐effective technique for single‐nucleotide polymorphism (SNP) genotyping and improve the efficiency to analyze degraded DNA, we have established a novel multiplex system including 21‐locus autosomal SNPs and amelogenin locus, which was based on allele‐specific amplification (ASA) and universal reporter primers (URP). The target amplicons for each of the 21 SNPs arranged from 63 base pair (bp) to 192 bp. The system was tested in 539 samples from three ethnic groups (Han, Mongolian, and Zhuang population) in China, and the total power of discrimination (TPD) and cumulative probability of exclusion (CPE) were more than 0.99999999 and 0.98, respectively. The system was further validated with forensic samples and full profiles could be achieved from degraded DNA and 63 case‐type samples. In summary, the multiplex system offers an effective technique for individual identification of forensic samples and is much more efficient in the analysis of degraded DNA compared with standard STR typing.     

GC Analysis of Black Gel Pen Ink Stored under Different Conditions

In many criminal and civil cases in China, the most commonly questioned documents are those written with gel pen ink. An important task for forensic document examiners is to identify whether two or more ink entries in one or more documents were written with the same ink type. The identification of the age of gel ink entries made poses an important and difficult problem for forensic document examiners. In this paper, the volatile components of gel ink were determined and the gel ink was classified by gas chromatography with a flame ionization detector. Calibration curves were created to express the relationship between the content of volatile gel ink components and the age of gel ink entries stored under natural and UV‐induced aging conditions. The correspondence between the natural and UV‐induced aging conditions was also established. The experimental results showed that GC was useful in the analysis of black gel ink and applicable for determining the relative age of gel ink entries under certain conditions.

中国-巴西基础设施建设合作:进展、挑战与路径选择

当前中国-巴西基础设施建设合作在港口、电力及交通设施领域已取得进展。巴西基础设施建设薄弱造成的投资需求,在中国-巴西坚实的双边关系以及“一带一路”倡议走入拉美地区的背景下迎来了新机遇。但高投融资成本、制度不完善、经济波动以及营商环境不利都限制了双边合作的进一步扩大。未来,中国巴西双方应着力推动合作机制常态化,创新投融资机制,重视人文交流,实现投资企业多元化发展,从而带领中国-巴西基础设施建设合作进入新时代。     

非洲猪瘟TaqMan实时荧光定量PCR检测方法的建立与应用

为建立检测非洲猪瘟病毒(African swine fever virus,ASFV)的快速诊断方法,本研究根据ASFV SY18株p17蛋白的编码基因D117L的保守序列设计并合成引物和探针,建立了基于ASFV p17蛋白的编码基因D117L的TaqMan荧光定量PCR检测方法,并验证其特异性、灵敏性和重复性。结果显示,本研究建立的TaqMan荧光定量PCR检测方法的C_t值与标准品在1×10^9~1×10^1copies/μL范围内呈良好的线性关系,相关系数为0.998,斜率为-3.192,检测下限为10 copies/μL,且与其他能引起相似症状的猪源病毒无交叉反应。重复性试验结果显示,组间与组内变异系数均小于1.920 7%,重复性好。此方法可用于ASF的早期诊断和ASFV快速检测。
