    近些年来,关键链方法(CriticalChainMethod,CCM)被越来越多的应用到各行各业多项目管理领域中,成为多项目管理领域的研究热点之一。关键链法是在约束理论(TheoryofConstraints,TOC)的基础上发展起来的,与传统项目管理的关键路径法(CPM)和计划评审技术(PERT)相比,关键链法在制定项目实施计划时就考虑了资源的约束性。并在项目管理过程中运用缓冲区动态监控的方法,持续不断的改进项目的进度计划。当前,关键链技术在有资源争夺的多项目进度计划制定中发挥了其显著作用。该方法基于关键资源约束,通过识别项目的关键链,设置缓冲区,能够尽量避免由于资源冲突和人为因素对工期估计...In recent years, Critical Chain Method (CCM) is applied to the field of multi project managements more and more, which has become one of the research hotspots in this field. Based on the Theory of Constraints (TOC), the Critical Chain method is developed, comparing with CPM and PERT, CCM considered the constraint of resource, while scheduling the project. And in the process of project management, ...学位:工程硕士院系专业:管理学院_工程硕士(项目管理)学号:X200915306

    90年代以来,互联网等信息技术高速发展,给政府管理的改革与创新带来很多机会与挑战,为了适应信息化的发展趋势并且为公众提供更好的政府管理服务,“电子政务”的概念逐渐进入人们的视野,根据《中华人民共和国行政许可法》第33条规定指出各类行政单位应积极推进电子政务建设,而政府网络办公系统是真正意义上实现电子政务的第一步。 目前,国内各级政府都已经有了自己的政务办公系统,国内大中城市更是投入巨大的人力和财力建设政府网络办公系统,各大政府的网络办公系统已经基本实现了信息发布、工作宣传等基本功能,但是还没有跟上网络发展的趋势,大部分网络办公系统在功能和运营管理上没有切实做到满足办公人员的需要,还没有真正的...The Information technology has been developping at a high speed such as Network in the 90’s, which brings enormous challenges and opportunities to the reformation and innovation of government management. To adapt to the tendency of informatization and supply better service to the public, the concept of EG (e-government) is coming into the people’s horizons.

    An ultra-thin amniotic membrane preparation and its application as carrier in corneal epithelium tissue-engineering

    目的:羊膜是目前应用最广泛的构建组织工程角膜上皮的载体。但在临床应用中发现,基于羊膜构建的组织工程角膜上皮在移植术后角膜的透明度恢复并不理想。目前认为,羊膜基质的纤维细胞层及疏松的海绵层可能是影响羊膜透明度的主要原因。因此,本研究对传统去上皮羊膜(DAM)进行改造,制备一种新型的超薄羊膜(UAM)载体,并评估其生物学及光学性质,同时探讨使用该种载体构建组织工程角膜上皮的可行性。 方法:本研究利用0.02%的EDTA去除失活羊膜组织的上皮细胞,并采用IV型胶原酶消化去除羊膜基质的纤维层及海绵层,从而获得羊膜致密层。比较从不同位置来源的胎儿面及胎盘面羊膜,选择合适的羊膜来源。以传统的完整羊膜(I...Purpose: Amniotic membranes (AM) are widely used as a corneal epithelial tissue carrier in reconstruction surgery. However, the engineered tissue transparency is low due to the translucent thick underlying AM stroma. To overcome this drawback, we developed an ultra-thin AM (UAM) by stripping away from the epithelial denuded AM (DAM) some of the stroma, and evaluated its biomaterial characteristics...学位:理学博士院系专业:医学院_生理学学号:2452013015432

    根据中国银行业监督管理委员会2016年初发布的数据,至2015年四季度末,我国商业银行不良率已连续10个季度上升、不良贷款余额已连续16个季度增加,商业银行信贷资产质量管理面临前所未有的压力。2016年随着供给侧结构性改革的推进,实体经济在去产能、去库存、去杠杆的过程中,商业银行信贷资产质量管控压力进一步增大。在这一背景下,对国有控股银行不良贷款影响因素的研究具有现实意义。 首先,通过国内外学者关于不良率影响因素理论研究、法人和零售贷款的比较分析,明确本文以法人贷款为研究对象,再从A市某国有控股银行B分行的实务出发,选取最具代表性的批发零售业、制造业和房地产业为法人贷款的比较行业。其次,构建...According to data released by the China Banking Regulatory Commission, by the end of the fourth quarter of 2015, the ratio of non-performing loans to total gross loans(“non-performing loan ratio”) and non-performing loan balance of China's commercial banks has been increasing for 10 and 16 consecutive quarters respectively. China’s commercial banks are facing unprecedented pressure of loan qualit...学位:金融硕士院系专业:经济学院_金融硕士学号:1562014115208

    因脊椎动物的血清与黏液中含有大量蛋白质及其他生物活性物质,而具有多种生理、生化与抗病防御功能。为了解水生脊椎动物血清与黏液中所含主要蛋白成分及其异同,我们分别从中华鲟(Chinese stur-geon Aclpenser sinensis grdy)、鲫鱼(Crucian carp Carassius auratus)、草鱼(Grass carp Ctenopharyngodonidellus)、赤点石斑鱼(Red-spotted grouper Epinephelus akaara)、青石斑鱼(Banded grouper Epinephelusawoara)、狗鱼(Pikes Esox reicherti)、江豚(Finless porpoise Neophocaena phocaenoides)、黄颡鱼(Yellow catfishPelteobagrus fulvidraco)、鳜鱼(Mandarin fish Siniperca chuatsi)这9种水生脊椎动物中,采集血清和皮肤黏液样本。利用考马斯亮蓝G-250法,测定了不同水生脊椎动物的血清和黏液样品中总蛋白的含量;经SDS-PAGE蛋白电泳,分别获得不同水生脊椎动物血清及黏液蛋白图谱;比较和分析了同种动物血清和黏液、不同动物之间血清与血清或黏液与黏液之间蛋白图谱的差异。结果表明:这些动物的血清蛋白组分有显著相似性,在分子量45—120 kD之间,蛋白条带大量集中分布;除青石斑鱼外,其他8种水生脊椎动物都有分子量约为28 kD和14 kD相同或相近的两条蛋白带。草鱼、鲫鱼、鳜鱼、狗鱼、黄颡鱼和江豚的黏液蛋白,除了都含有分子量大小约为45 kD的蛋白条带外,其他无显著相似性。对同种水生脊椎动物的血清与黏液蛋白比较,虽然黄颡鱼的血清与黏液中分子量相近的蛋白带最多,也仅约为38%,可见其蛋白带的种类和含量都存在显著差异

    随着我国经济的快速发展,资源紧缺、环境污染问题越来越凸显,经济的发展带来的是生态环境的毁坏。各种环境问题特别是流域污染问题危害严重,尤其是厦门市集美区许溪小流域内,基础设施配套建设欠债严重,沿溪村庄没有排污管网设施,村庄内小工厂、小作坊众多,工业面源、农业面源污染指数不降反升,导致出现“三农困境”——农业发展转型提升难、农村生产生活环境改善难、农民收入持续增收难。流域是人类社会、经济和生态系统共享的宝贵财富,国家把生态文明建设提升到“五位一体”的高度,同时重点加强流域治理更是社会的发展趋势,但原有政府单一行政治理方式弊端的暴露,加快了流域治理模式的衍生,也将协同治理理念引入流域综合治理中。 ...With the rapid development of China's economy, the shortage of resources, the problem of environmental pollution have became increasingly prominent, but the economic development has brought the destruction of the ecological environment.

    Forms and Functions of Copulas: A Study on Nominal Predicate Sentences

    Get PDF
    前人对系词的认识,大致有“连接说”“傀儡说”“谓词说”三种观点。这些观点都有局限,特别不适用于汉语。本文从共时和历时的角度,跨语言描写系词隐现的规律,从而揭示系词的功能并解释名词谓语句,得知系词的作用是标明或强调“话题-述题”关系,即“增强标述性”功能。词类句法语法化程度较高的语言(如英语),系词是语法性质的、刚性的,语法上规定了系词是否出现;词类句法语法化程度较低的语言(如汉语),系词是语用性质的、柔性的,“话题-述题”关系是否明确或是否需要强调,决定是否出现系词。Theories on the functions of copulas normally include Linker Hypothesis, Dummy Hypothesis and Predicatot Hypothesis, all of which have their limitations, especially when applied to Chinese. In a cross-linguistic perspective, the present paper describes the copulas synchronically and diachronically, revealing that the functions of copulas are to indicate or emphasize the interpretation of "topic-comment", i. e. predicate-indicator. Copulas are obligatory in more grammaticalized languages (such as English) , and thus they are called grammatical copulas. In less grammati- calized languages (such as Chinese), the interpretation of "topicomment" relation resorts to context and world knowledge. Copulas in these languages are optional and are thus called pragmatic copulas.本文是第一作者的博士论文相关章节经两位作者延续研究而成,感谢导师沈家煊先生悉心指导.本文还蒙陈刚、陈满华、龙海平、完权、朱庆祥等多位学友提出改进意见,《外国语》审稿专家也提出不少意见和建议,受益良多.尚存谬误,均归笔者.教育部人文社会科学研究项目“基于并置关系的汉语(教学)语法体系研究”(15YJC740130);中央高校基本业务费资助项目“基于语言类型学的汉英教学研究”(20720151167);福建省社科规划项目“基于英汉结构对比的阅读技巧研究”(2014C015)
