当前金融犯罪的主要特点与对策分析

当前经济犯罪的危害越来越严重,在经济犯罪中又以金融犯罪危害更为突出。目前金融犯罪大案、要案大幅度上升,作案手段呈智能化、多样化、隐蔽化,危害重大,严重影响了社会稳定,给社会造成了不可估量的经济损失,更对社会经济秩序乃至整个社会秩序产生了严重破坏。因此,制定科学、有效及切实可行的打击对策是当前公安工作的当务之急。     

地方公务人员"规范补贴"不规范的危害及其治理

公务员收入分配是整个社会收入分配的重要组成部分.始自2006年7月开始的我国第四次公务员工资改革,最明显的效果就是规范了补贴方式,但是,由于一些地方政府背离了中央关于公务人员工资改革的初衰,使得公务人员"规范补贴"不规范,对此必须予以重视并采取相应措施进行治理.     

基于现金流量的财务风险预警体系探析

国内外研究表明,现金流量在财务困境企业与非财务困境企业之间有显著差异,现金流量具有财务预警能力。从现金流量的角度,在对现有的财务风险预警模型比较分析的基础上,研究建立基于现金流量的财务风险预警体系是非常必要的。     

Economic effects estimation for the Eurasian Economic Union: Application of regional linear regression

This paper aims to provide a coherent analysis of the economic impact accession to the Eurasian Economic Union has had on the economies of current member states and what affect membership would have on the economy of Azerbaijan. By applying a Linear Regression Model we find that membership to this regional bloc has yielded minimal financial benefits for the existing members. However, for most states, accession has increased the trade deficit with Russia and that a membership would likely produce a similar negative outcome for Azerbaijan in addition to undermining national economic and energy policy making.     

African farmer-led irrigation development: re-framing agricultural policy and investment?

The past decade has witnessed an intensifying focus on the development of irrigation in sub-Saharan Africa. It follows a 20-year hiatus in the wake of disappointing irrigation performance during the 1970s and 1980s. Persistent low productivity in African agriculture and vulnerability of African food supplies to increasing instability in international commodity markets are driving pan-African agricultural investment initiatives, such as the Comprehensive Africa Agricultural Development Programme (CAADP), that identify as a priority the improvement in reliability of water control for agriculture. The paper argues that, for such initiatives to be effective, there needs to be a re-appraisal of current dynamics of irrigation development in sub-Saharan Africa, particularly with respect to the role of small-scale producers’ initiatives in expanding irrigation. The paper reviews the principal forms such initiatives take and argues that official narratives and statistics on African irrigation often underestimate the extent of such activities. The paper identifies five key characteristics which, it argues, contradict widely held assumptions that inform irrigation policy in Africa. The paper concludes by offering a definition of ‘farmer-led irrigation’ that embraces a range of interaction between producers and commercial, government and non-government agencies, and identifies priority areas for research on the growth potential and impact of such interactions and strategies for their future development.     

A群猪轮状病毒胶体金免疫层析试纸条的研制

为建立一种快速、简便的猪轮状病毒检测方法,采用柠檬酸三钠还原法制备胶体金颗粒,标记纯化的抗猪轮状病毒VP6蛋白单克隆抗体,在硝酸纤维素膜上喷加纯化的抗猪轮状病毒VP6蛋白多克隆抗体和羊抗鼠IgG,制成检测猪轮状病毒抗原的胶体金免疫层析试纸条。结果表明,所制备的试纸条用于检测猪轮状病毒感染的MA104细胞培养物,在检测线处出现红色反应带,未感染病毒的细胞培养物在检测线处未出现反应条带,上述培养物在质控线处均出现红色反应条带;进一步试验表明,试纸条检出病毒培养液(TCID50是10-6.25/0.1 mL)的最低限为1∶32稀释;用不同批次的试纸条重复检测,结果无差异;该试纸条不与相关的腹泻病毒猪传染性胃肠炎病毒、流行性腹泻病毒发生反应,所制备的试纸条具有一定的敏感性和特异性,重复性良好。     

牛D型产气荚膜梭菌肠毒血症间接ELISA诊断方法的建立

根据菌体蛋白可以刺激机体产生相应抗体的原理,建立了以产气荚膜梭菌粗提菌体蛋白为抗原的检测牛D型产气荚膜梭菌抗体的间接ELISA.结果显示,D型产气荚膜梭菌菌体裂解抗原最适包被浓度为50 μg/mL,最适包被条件为37 ℃ 1 h;被检血清的最适稀释度为1∶100,酶标二抗的最适工作浓度为1∶1 000,血清与酶标二抗的反应时间均为37 ℃ 1 h;最适封闭时间为37 ℃ 1 h;PBST稀释液中脱脂乳的浓度为30 g/L;底物最适反应条件为室温25 min;阴阳性临界值为0.032.对采集于吉林省延边州的100份牛血清样品采用建立的间接ELISA进行了检测;结果,阳性率为11.0%.经特异性试验、重复性试验和与琼脂扩散抗体检测法比较,采用裂解菌体蛋白为抗原建立的ELISA方法具有良好的特异性、敏感性和重复性.     

Lip print enhancement: review

Lip print(LP)evidence can be an essential tool for human forensics.LPs have conventionally been developed using substances such as lysochrome dyes,fluorescent dyes,indigo dye,aluminium powder,and silver metallic powder.However,techniques for LP enhancement from various substrates are currently inconsistent and lack standardisation in practice.This review summarises current knowledge on the physical and chemical techniques of LP enhancement,identifies limitations,and provides suggestions for future research on practical applications of cheiloscopy as a forensic tool in criminal justice.     

程序正义理论的再梳理:从《正义论》到《政治自由主义》——遵循罗尔斯思想发展的轨迹

在1971年出版的<正义论>里,罗尔斯将程序正义分为:完善的程序正义、不完善的程序正义、纯粹的程序正义;并认为:纯粹的程序正义决定了结果的实体正义.在学术界,罗尔斯的程序正义理论产生了涟漪:赞同观点和反对主张同时存在.作为自身学术思想的发展,在1993年出版的<政治自由主义>里,罗尔斯修订了其在<正义论>里的观点,认为:程序正义的正义性,部分依赖结果的实体正义性.学术思想的修正,并不代表罗尔斯对程序正义理论的放弃,而是加强了程序正义理论的现实实践基石.
