论公司形式的中小企业治理结构的依据——以一人公司治理结构为例

一人公司制度的出现和日益普及,对传统的公司治理结构理论提出了严重的挑战,实际上也暴露了西方传统公司治理结构理论基础的局限性。以所有权与经营权“两权分离”和“效率至上”作为公司治理结构的基本理论前提和价值取向是完全不适当的,是对所有者与经营者“两者分离”的误读和误解。以公司形式出现的中小企业,实际上体现了现代企业制度向中小企业的延伸,所以中国企业制度的改革应当摒弃以产权制度改革为中心的模式,转移到以建立现代企业治理结构的方向上来。     

网络考试系统分析

组织学生考试是高校重要的工作,但现在的考试形式大多是教师手工出题、阅卷,虽然出现了相应的答题卡形式,减少了老师一定的阅卷负担,但效率还是较低的。利用网络和数据库技术,结合目前硬件价格普遍下跌与宽带网大力建设的有利时机,基于B／S模式研究开发了试题库与在线考试系统。它运用方便、操作简单,效率较高,同时也大大减轻了教师出题、组卷和改卷等繁重的工作量。     

Maximizing order or harm? Arrests among a social network of people who inject drugs in a large urban city

Encountering the criminal justice system at the first point of entry---an arrest---is associated with heightened HIV and Hepatitis risk behavior among people who inject drugs (PWIDS). Intervening structurally through the criminal justice system impacts public health; therefore, determining arrest patterns is an important tool for risk reduction. Among a sample of 740 PWIDs, and their social network members recruited from predominantly African-American neighborhoods in Baltimore City, a third were recently arrested in the previous six months, and of those, the arrests were disproportionately African-American persons and characterized as nonviolent, i.e., drug possession/attempt to purchase (38%) and loitering (29%). Poisson regression models were built adjusted for age, sex, race, education level, homelessness, and monthly income after exploring bivariable characteristics of arrests using chi-squared tests. Active drug use was associated with a recent arrest (adjusted prevalence ratio: aPR 2.38 95% CI 1.6, 3.6), in addition to participants who recently reported attending a syringe exchange program (aPR 1.45 95% CI 1.1, 2.0). Our findings are suggestive of recent media coverage and burgeoning research revealing the prioritization of policing resources toward both communities of color and neighborhoods of intensified drug trafficking. Further research is warranted to contextualize the operationalization of criminal justice resources and the impact on community health.     

Automated estimation of the number of contributors in autosomal STR profiles

Estimating the number of contributors to mixed STR profiles can be complex. This study describes the nC-tool to assist DNA expert in this process. The nC-tool is based on the total allele count for PowerPlex® Fusion 6C profiles and showed improved performance when compared to the maximum allele count approach.     

从白小保校运动看马来西亚华人的政治参与形态

马来西亚华人有着积极的政治参与的传统,近些年来更是利用各种途径来最大限度地表达与维护其利益.2001年来持续四年的白小保校运动主要通过政治选举、政治结社、政治表达、政治接触等方式来维护子女接受母语教育、文化传承的权利.这一典型事例体现了马来西亚华人政治参与的基本模式.     

口蹄疫病毒3C基因与增强型绿色荧光蛋白基因的真核共表达

为验证siRNAs对口蹄疫病毒(FMDV)复制的抑制效果,用反转录聚合酶链反应(RT-PCR)扩增Asia 1型口蹄疫病毒Jiangsu/China/2005株的3C基因,克隆入增强型绿色荧光蛋白(EGFP)表达载体pEGFP-N1中,并进行双酶切、PCR及测序鉴定。将阳性重组质粒转染PK-15细胞,检测EGFP的表达和3C基因转录水平。结果显示,经PCR及双酶切鉴定,目的基因片段大小与预期相符,测序结果与Jiangsu/China/2005株相应序列一致。荧光显微镜和流式细胞仪均检测到细胞内有EGFP表达,实时荧光定量PCR检测到细胞内有3C基因的转录。证实,成功构建了FMDV 3C基因与EGFP共表达质粒并在PK-15细胞中获得了表达。     

新《保险法》对中国海上保险合同法律的影响

2009年2月公布的《中华人民共和国保险法》在很多方面进行了重大的修改,势必对中国海上保险合同法律制度产生重要影响。一方面是对海上保险合同法律的补充,另一方面同《中华人民共和国海商法》在海上保险合同不少制度和规则上出现了程度不同的差异。而这些也为后者未来的修改提供了丰富的素材和良好的借鉴蓝本。

The Future of Consumer Web Data: A European/US Perspective

The article considers the subject of clickstream data from aEuropean/US perspective, taking into account the Data ProtectionFramework (Data Protection Directive 95/46/EC; Directive onPrivacy and Electronic Communications 2002/58/EC) and the USlegal framework and in particular, the Wiretap Act U.S.C. 2701(2004) and related statutes. It examines the extent to whichclickstream data is considered "personal data" within the DataProtection Directive and the implications to consumers and businesses.     

“任务驱动”教学模式在C语言教学中的应用

C语言程序设计的教学在高校计算机课程教学中一直处于比较重要的地位,如何培养学生的编程能力和实际动手能力以适应社会的需求,是许多教师、专家和学者比较关注的问题。在此,以当前C语言教学中存在的问题入手,提出在C语言教学中应用＂任务驱动＂教学模式来提升学生的能力,强调以任务为中心,以学生为主体,以教师为主导,以课程设计为辅助,使学生在任务探究过程中掌握知识与技能,培养创新思维,提高实践能力,从而达到教学目标,提高教学质量。
