Research on the Definition of Refusal to Deal

合同自由是民事活动的基本原则，但合同自由不是绝对的，而是相对的。依照我国《反垄断法》第17条的规定，如果经营者滥用市场支配地位拒绝与交易相对人进行交易，则要受到反垄断法的规制，构成合同自由的一种例外情形。 拒绝交易行为是指具有市场支配地位的经营者无正当理由，拒绝和交易相对人进行交易的行为。在认定经营者拒绝与交易相对人进行交易的违法性时，需要进行科学、严谨的分析，以准确界定经营者的行为是合同自由的体现还是反垄断法规制的拒绝交易行为。近几年来，我国陆续查处一些涉及拒绝交易行为的案件。经营者在未来也有可能滥用市场支配地位实施拒绝交易行为，以排除、限制市场竞争。因此，如何准确认定拒绝交易行为，是我国...Freedom of contract is the basic principle of civil activities. Freedom of contract is not absolute, but relative. According to the Article 17 of Chinese Anti-Monopoly Law, if the operators abuse their dominant market positions and refuse to enter into transactions with their trading counterparts, they are subject to the regulation of the anti-monopoly law and constitute an exception to the freedo...学位：法律硕士院系专业：法学院_法律硕士学号：1302014115025

Cloning，Expressing and Identification of Aspartic Protease Gene and Cathepsin B Protease Gene from Ancylostoma caninum in E.coli

钩虫是重要的人兽共患寄生虫,寄生于人体可导致贫血，儿童感染钩虫后造成发育迟缓，为了解肠道线虫在儿童中的流行情况和开展儿童肠道线虫病的防治，我们于2004年7月至10月间进行了厦门市儿童肠道线虫感染调查。通过收集儿童粪便，采用饱和盐水漂浮法收集虫卵并镜检计数,以透明胶纸拭擦法检查蛲虫卵。调查发现厦门市儿童肠道线虫感染率为13.79%,全为蛔虫感染；蛲虫感染率为8.87%。岛内儿童的感染率为11.96%，岛外儿童的感染率为15.32%。各幼儿园的感染率有明显的差别。蛔虫感染中,感染率最低为5.00%,最高为26.67%；蛲虫感染中,感染率最高为25.93%。蛔虫感染中,男童感染率为12.24%，女...Hookworm is a important intestinal parasitic nematodes in human,in order to ensure children grow healthily and to study the infection of the intestinal nematodes in the children, 406 children’s faeces were collected and checked in the laboratory.

CDM下我国碳金融发展的思考

2009年,哥本哈根联合国气候变化会议将低碳经济理念渗透到了当今世界的发展潮流中。随之而来的碳金融行业发展势头强劲,得到越来越多国家经济体的重视。然而和国际相关机构相比,中国碳金融市场的发展面对复杂的清洁发展机制(简称CdM)的开发流程还相当不成熟。在这样的背景下,本文旨在通过深入剖析中国CdM产业链,探究碳金融行业存在的不足;同时提出面对这些缺陷,中国政府机构、商业银行、企业究竟应该如何把握机会,争取主动权,为碳金融在中国的发展铺平道路

Family Control, Institutional Environment and Cash Dividend Policy

随着20世纪90年代家族控制的上市公司逐步进入西方学者的视野，他们开始对其展开激烈的研究，但是在很多领域意见尚未统一。与此同时，以LaPorta等学者为代表的学者将法律环境制度引入公司的研究，掀起了一场“法与金融”的浪潮。本文基于家族控制与治理环境的双重视角，收集了2004-2007年1486家A股上市公司的资料，应用Logistic回归与Tobit回归的方法，实证研究了家族控制和治理环境对公司现金股利支付意愿和支付比例的影响，将家族控制与治理环境这两种内、外部公司治理机制纳入统一的分析框架来探讨其对上市公司现金股利政策的影响，还考察了治理环境作为外部治理对于改善内部治理的积极作用。 本文共...As the family controlled listed companies came into western scholars’ view in 1990s, they start to begin the research intensely, but still lots of disagreements in many fields were left unsolved. At the same time, the scholars, represented by La Porta et al, introduce the law environment into the study of companies, setting off a wave of “law and finance”.

Asset Pricing with View Bias Ajjustment under Imperfect Information

资产定价理论构建了资产定价框架，再该框架之下，任何或有索取权的价格等于该或有索取权的最终收益经由随机贴现因子贴现后得到的贴现值的数学期望。然而，该理论并不能与很好地与实际数据相吻合。问题主要体现在如下两个方面:第一，从随机贴现因子的均值方差角度来看，存在股权溢价之谜、无风险利率之谜和相关性之谜；第二，从随机贴现因子的因子结构来看，存在规模效应、价值效应和动量效应。 论文的主要目的是要将信息的不确定性引入到资产定价的理论框架中来，并希望，该扩展的模型能够解释上述两大类资产定价的异常现象。本文的主要创新在于建立了新的内在一致的风险收益度量体系，使得该体系能够体现出投资者面对模糊信息产生观点偏差的...The fundamental asset pricing theory established an asset pricing framework, that is, the asset price of any contingent claim is the expectation of its terminal payoff discounted by a stochastic discount factor (SDF).

Study on Ancylostoma caninum in dogs and the observation of different stages of life cycle

目的犬钩虫(Ancylostoma canium)幼虫可以感染人体,但不能发育为成虫,仅引起皮肤幼虫移行症。方法采用饱和盐水漂浮法和涂片法检查钩虫卵;用"T"滤纸条培养犬钩蚴;皮肤感染和灌喂人工感染实验狗。感染后不同时间解剖狗,从狗小肠获取钩虫,镜下观察和拍照。结果厦门市30只宠物犬样本犬钩虫感染率为3.33%(1/30),蛔虫感染率为10.00%(3/30)。对犬钩虫生活史各期的形态进行观察。结论厦门市存在宠物犬犬钩虫感染,特别是农家狗的犬钩虫感染为多。Only the larvae of Ancylostoma canium infect human and emigrant in human body,they could not develop into abult.In order to get Ancylostoma canium,we investigated dog hookworm in summer and autumn of 2004.The eggs were floated by saturated NaCl solution and incubated on the "T" filter paper.The experimental dogs were infected with infective larva from skin and mouth.The parasite was collected from small intestine at different time of post-infection and observed via microscope.The results indicate that the infection rate of Ancylostoma caninum is 3.33%,and Ascaris lumbricoides is 10.00% in dogs,respectively.And the observation of different stages of hookworm's lifecycle were done.In conclusion,Ancylostoma canium is still popular in dogs in Xiamen,especially in the countryside.福建省自然科学基金重点项目资助(项目号:C0320001

Cloning,expression and identification of aspartic protease gene of Ancylostoma caninum in E.coli

目的对犬钩虫(Ancylostomacaninum)天冬氨酸蛋白酶Asp基因进行了克隆,鉴定,并在原核系统中进行表达。方法以犬钩虫总RNA为模板,用RT-PCR法对犬钩虫天冬氨酸蛋白酶Asp基因进行扩增,获得的AspcDNA产物克隆进pMD-18T载体,用PCR筛选阳性克隆。碱裂解法进行质粒提取,单、双酶切进行鉴定并测序。将测序正确的阳性克隆进行双酶切,构建到表达载体pET-32a中,将此重组质粒先转化到E.coliDH5a内,提取质粒,酶切鉴定阳性,再转化入表达宿主E.coliBL21(DE3)菌株内,对转化菌株用IPTG进行诱导培养。收集培养液,破菌、离心,上清进行SDS-PAGE,通过电转移将胶中蛋白转到硝酸纤维素膜上后进行免疫印迹分析。结果电泳发现转化了重组质粒的菌株有表达蛋白,所表达蛋白相对分子量为40kDa,抗体检测有特异条带大小为40kDa。结论成功进行了犬钩虫天冬氨酸蛋白酶Asp基因的克隆表达。Cloning,expressing and identify the aspartic protease gene from Ancylostoma caninum for the further studying in the application in the diagnosis of Ancylostoma as well as for the development of anti-hookworm vaccine.The gene encoding aspartic protease was amplified from the total RNA by using RT-PCR technique.The amplified product was cloned initially into pMD-18T vector.After PCR selection,enzyme digestion,and sequencing.The positive and right sequence of plasmid was digested by enzyme and ligated with digested expression vector pET-32a by ligase,and then transformed the construct into the competent E.coli DH5а strain.Colonies containing the insert plasmid were selected on LB plus ampicillin(100μg/ml) plate and also by PCR screening,the positive plasmid DNA was extracted and digested with enzymes.Plasmid containing the right insert were sequenced to confirm its identity,and then retransformed the recombinant plasmids into E.coli BL21(DE3)strain.Bacterial lysates from cultures induced with IPTG(1mmol/L) were directly loaded onto SDS-PAGE,and the proteins on the SDS-PAGE gel.Were transferred to nitrocellulose membrane,detected with antiserum against recombinant expressing aspartic protease.Through these procedures,a specific protein with a molecular mass of 40kDa could be visualized on gel.This recombinant expressing protein can be used for further studies in the detection of the effectiveness of immunity and the preparation of antigen and antibodies of aspartic protease in large scale.国家自然科学基金(No30470881);; 福建省自然科学基金重点项目(NoC0320001)联合资

Moving Object Detection Algorithm in Video Sequences

提出一种基于前景目标分类的视频序列中运动目标检测方法。该方法在RGB空间内建立了一种新颖的背景模型;为了解决背景更新“死锁”问题,提出了像素点的跳跃度函数和稳定性函数,将前景分类为静止目标、运动目标及虚假目标;最后提出了一种基于HSV颜色信息和一阶梯度信息的混合阴影剪除算法。实验结果表明,该方法能有效分割视频场景中的运动目标并鲁棒地分离目标及其阴影区域。An efficient algorithm of detecting moving objects in video sequences was proposed.An adaptive background model was built and subsequently the background model is updated by a foreground object classification based background update algorithm which can resolve the "deadlock" problem efficiently.An improved shadow suppression algorithm which combines HSV color information with first-order image gradient information was exploited to segment shadows.Extensive experiments results on indoor and outdoor image sequences demonstrate that the proposed system can effectively detects moving objects and suppresses their shadows.国家自然科学基金资助项目(60175008);; 国家创新研究群体科学基金项目(60024301
