对弱势群体的政策支持刍议——以武汉市A区实施分散按比例安排残疾人就业政策为例

关注弱势群体,给予弱势群体必要的政策支持是构建社会主义和谐社会的必然要求。残疾人属于弱势群体,因此,政府有责任通过多方位、多角度的政策支持促进其就业,增强其平等参与社会生活的积极性和创造性。本文通过对武汉市A区分散按比例安排残疾人就业政策的实施、政策实施的成效及存在的问题进行分析,在此基础上提出政策优化建议。     

Comparing civil law and common law systems for mergers and acquisitions An economic analysis

＂From the economic point of view, common law is more efficient than civil law.＂ Is this recent statement published in an economic report valid for mergers and acquisitions （M＆A）？ The main objective of this paper is to compare the legal performance of M＆A in France and in the United States. The purpose is to quantify the impact of both legal systems on the long-term performance of M＆A transactions. To carry out this research, a specific methodology was developed and the results of which are evaluated. Two legal structures for M＆A transactions were retained： the purchase of shares （share deal）, and the purchase of assets （asset deal）. Each of these acquisition structures was then subdivided into eleven steps composing the process, for example from preliminary information, letter of intent, due diligence, stock or asset purchase agreement, closing, to litigation with formal summons. Performance was then measured by taking into account time, cost, and satisfaction factors. The time factor was broken down into person-days and the number of days, weeks, or months required to complete each step. French and U.S. respondents were asked to fill out a questionnaire with reference to a specific acquisition project. A typical question was for instance： What is your estimate of working days to complete this step （person-days）？ Radar charts were used to compare the mean of each performance factor. In order to check for correlations among the performance factors, an inter-factors analysis （regression） was carried out. The research findings are presented in this paper. Results show that a share deal in France is generally cheaper and participants indicate a significantly greater amount of satisfaction than in the U.S. However, for the time factor, the results vary. The conclusion is that the application of the civil code rather than common law does not reveal substantial differences as far as M＆A transactions are concerned. One reason is that in both France and the U.S. these transactions are carried out following standard procedures in compliance with common contractual practices.     

黑恶组织犯罪的初查研判研究

在黑恶组织犯罪案件的侦办过程中,由于此类犯罪操作层面大,取证难,因而大量立案前的调查行为在打黑实践中比比皆是,如对黑恶组织的早期摸排经营,情报信息的甄别审查等。较之检察机关侦办职务犯罪案件的初查制度的日益成熟与规范,立法对黑恶组织犯罪立案前的调查行为并未专门规定,它还处于一个实践概念的层面。黑恶组织犯罪的初查研判在打黑实践中极为关键,是侦查工作顺利开展的基础,是启动黑恶组织犯罪专案侦查的保障。     

固相微萃取技术在毛发药物分析中的应用

固相微萃取（SPME）可与GC/MS、HPLC/MS等在线联用,实现分离、分析一体化的特点为其在毛发药物分析中的应用提供了可能性和良好的应用前景。本文对SPME技术在毛发中滥用药物如苯丙胺类、美沙酮、大麻、可卡因、利多卡因等及其相应代谢产物的分析研究及应用进展做一综述。     

Forensic DNA against wildlife poaching: Identification of a serial wolf killing in Italy

The recent expansion of the Italian wolf population through the Apennine and western Alps, after centuries of contractions, is causing conflicts with human activities leading to a rise in poaching or illegal killings. Here we show how molecular population genetics has been used to identify a suspect serial wolf killer. We analysed DNA extracted from a necklace made of ten presumed wolf canine teeth, confiscated in 2008 to a man living in the northern Italian Apennine (Liguria Region). Individual genotypes were determined using 12 unlinked autosomal microsatellites (STRs), mtDNA control-region sequences, a male-specific ZFX/ZFY restriction-site and three Y-linked STRs. Results indicate that the teeth belonged to six different individuals (three males and three females), which were assigned to the Italian wolf population with p > 0.90 by Bayesian procedures. One of these genotypes matched with the genetic profile of a male wolf previously found-dead and already non-invasively sampled in the same area. Another genotype matched with that of a female wolf non-invasively sampled twice in the same area 1 year before. These data are being used as forensic genetic evidence in the ongoing criminal trial against the suspect serial wolf killer.     

高校学生户籍制度的弊端解析

随着经济体制的转变,现行高校学生户籍制度的弊端日益暴露出来。户籍管理工作量大、容易出错,"人户分离"、"口袋户口"现象严重,影响了学校的管理,影响了大学生的流动和就业。个中原因主要是滞后的高校学生户籍制度不符合高校改革的要求,不符合社会发展的需要。为此,应采取有针对性的措施以解决这些弊端。     

网络舆情引导与警察公共关系

网络舆论是社会舆论的放大器、思想文化信息的集散地和群体极化倾向的助推器。网络舆论给公安工作可能带来负面影响,引发严重的警察公共关系危机。公安机关要通过健全工作机制、加强网络监管、提高舆情研判能力、发挥"主场优势"、争抢舆论"旗帜"等方式对网络舆论进行有效引导。     

我国农民专业合作社法律地位剖析

2006年10月31日我国颁布了《中华人民共和国农民专业合作社法》,明确了农民专业合作社的法律地位。但是现实生活中,我国还存在大量仅有合作之名而无合作之实的农村合作经济组织。因此,从理论层面厘清农民专业合作社与非合作社之间的界限,在法律上澄清并确定农民专业合作社的主体地位,对于促进我国农民专业合作社制度的发展及保障现行法律的正确实施具有十分重要的现实意义。
