A Study on Standard Competition and its Strategies with Network Effect: Analysis Based on Evolutionary Game Model
在网络经济时代,技术创新速度越来越快,企业所面临的市场环境也因此日趋复杂多变。为了在激烈的市场竞争中生存和发展,企业开始采用标准这一竞争工具。在具有网络结构的产业中,不同于传统产业的一个重要特征就是“网络效应”。网络效应在本质上是一种需求方规模经济,并与古典经济学所研究的供给方规模经济有着较大的区别。由于网络效应的存在,标准竞争中产生了新的现象和特点,因此有必要更新传统的经济学理论,让理论能够更好解释现实和提供建议。 本文首先定义了网络,并将网络分成物理网络和虚拟网络、单向网络与双向网络。这些区分有利于理解网络效应的起源和分类。本文认为,网络效应起源于互补性,包括了结构互补性、功能互补性、信...In the era of Network Economy, the speed of innovation is growing faster and faster; therefore, the market environment that the firms are facing is becoming more complicated. To survive and develop in the fierce market competition, firms start to use standard competition as the main competition tool. In the industries that has the network structure; one significant difference from the traditional ...学位:经济学硕士院系专业:经济学院财政系_网络经济学学号:1552006115097
如何认识与评价世界一流大学的“全球性”潜在特征
世界一流大学映射了极少数大学的精英地位,这是一个模糊的质量概念,既没有明显的边界来区分与其他大学的差别,也缺乏可行的评价标准。国际上,对一流大学评价的通用方法是量化指标排序,但最终指向的是"全球性"认可这一潜在特征,可以概括为:全球性声誉、全球问题研究能力、适应全球变革的战略、参与全球竞争的能力,以及立足本土的全球性价值。这些潜在特征是我们认识和评价一流大学的基础。教育部高等教育评估中心课题“一流大学建设高校本科教学质量监测报告”研
Studies on the methods for Tea Main Components Analysis and Fingerprinting Technology
茶叶是我国的主要经济作物,长期以来,茶叶的质量控制以安全检测为主,即系统测定茶叶中铅、铜、砷等重金属含量以及茶叶中六六六、DDT、三氯杀螨醇、氰戊菊酯等化学农残。事实上,茶叶的质量控制应是一个广义的概念,涉及到茶叶产地信息的明确、质量的稳定、等级的认定等多方面的内容。目前我国市场上茶叶商品质量极度混乱,以假充真、以次充好的现象普遍存在,中国茶叶今天这种混乱局面,与我国作为茶叶大国的地位是极不相称的,严重影响了我国茶叶的发展,市场渴望有科学的评定方法,茶叶质量控制标准化工作势在必行。不同地方栽培、不同栽培方法、不同的采摘期、不同的加工方法生产出的茶叶,在理论上应该有显著差异,茶叶的产地也很重要,...Tea is one of the most popular beverages in the world, and has great economic value. Up to now, activities on the quality control of tea have been concentrated primarily on monitoring toxic elements such as lead, copper, arsenic, and pesticide residues including BHC, DDT, dicofol, fenvalerate, etc. In fact, a comprehensive qulity control process should include much broader range of activities suc...学位:理学硕士院系专业:化学化工学院化学系_分析化学学号:20032502

The Subject Value of Professional Evaluation of Higher Education Should Return to Students
专业评估的通常做法是以专业教学目标的合理性判断为起点,在标准选择上更倾向于教育者和管理者的标准。本文认为,专业评估应该以结果指标,即毕业生质量为评估的逻辑起点,并在评估中突出学生的主体地位和成长价值,评估标准的选择应该从外在的显性数量化指标回归到内在的学生成就等隐性指标。Usually, the starting point of professional evaluation is the speciality teaching target.In detail, it starts with the rationality of arrangement of professional teaching.The selection of evaluation standards is more intended to educators and managers.The authors present that the correct way is to start with the results of speciality teaching, in other words, the quality of graduated students should be the main body, and the emphasis should be the values in students' development.The evaluation standards should return to internal indexes such as students' achievement and development from the external indexes such as teaching times, amount of books and areas of classrooms, the number of teachers, etc.云南省高职研究重点项目《基于学业标准的高职院校学习性评价研究》(项目编号:7ZD201310); 教育部哲学社会科学研究重大课题攻关项目《中国现代职业教育质量保障体系研究》(项目编号:13JZD047)子课题《高职教育专业认证及评估的研究与实践》成果之
American Higher Education Professional Evaluation Is Based on Students' Academic Achievement
近年来,高等教育的产出及培养质量受到社会各界的广泛关注,美国高等教育专业认证从高校资源和声誉的维度逐渐转向学生学习成果的维度。本文在分析美国专业认证中如何运用学习成果评估的基础上,提出了今后我国专业评估应在评估主体上突出学生地位,在评估过程中应根据院校特征建立有特色的学生学习成果评估模型,进一步强调学生的学习“结果“评估。Recent years, the production of the higher education and its educational quality were widely noticed by the public in our society.American higher education professional evaluation has made transactions from the university resources and reputation to the students' achievements.This study analyzed the American professional evaluation how to use academic achievements as evaluational indicators, and proposed to treat student as evaluation body in professional evaluation in our country, and built a featured student evaluation model and stress of the evaluation on students' academic results.云南省高职研究重点项目《基于学业标准的高职院校学习性评价研究》(项目编号:7ZD201310); 教育部哲学社会科学研究重大课题攻关项目《中国现代职业教育质量保障体系研究》(项目编号:13JZD047)子课题“高职教育专业认证及评估的研究与实践”成果之
Establishment of MDCK cell lines which stably express visualable human neonatal Fc receptor
[目的]建立稳定表达融合EGFP的人新生儿Fc受体(h FcRn)的MDCK细胞株。[方法]构建重组慢病毒质粒p EGFP-h FcRn,采用四质粒包装系统共转染HEK 293T细胞生产重组慢病毒,感染MDCK细胞后对EGFP阳性细胞进行流式单细胞分选;通过Western Blot及EGFP-β2m荧光共定位验证h FcRn的完整性,并用流式细胞仪检测h FcRn与人Ig G的结合活性。[结果]测序结果表明成功构建p EGFP-FcRn慢病毒表达载体;感染后EGFP阳性MDCK细胞比例约为26.5%,流式单细胞分选后得到纯阳性细胞;荧光共定位及Western Blot均检测到h FcRn的完整表达;流式分析表明细胞株上的h FcRn与Ig G存在p H依赖性结合。[结论]成功获得稳定表达具有生物活性的可视化h FcRn的MDCK细胞株。[ Objective] To establish MDCK cell line stably expressing EGFP- human neonatal Fc receptor(hFcRn) fusion protein. [ Methods ] The lentiviral expression vector for EGFP - hFcRn fusion protein was constructed. Generating by co - transfection of four -plasmids into HEK 293T cells ,the lentivirus particles were used to infect MDCK cell line. EGFP positive single cell was obtained by FACS, and then FcRn expression was identified by fluorescence co -location with EGFP - β2m and confirmed by Western Blot. Flow cytometry was used to detect binding activity of hFcRn and human IgG. [ Results ] DNA se- quencing demonstrated that the lentivirus vector pEGFP - FcRn was constructed successfully. The percentage of EGFP - posi- tive ceils was about 26.5% after infection. Expression of the complete protein was detected through fluorescence co - location and Western Blot, respectively. Flow cytometry analysis showed that the cell lines could pH - dependently capture human IgG. [ Conclusion] MDCK cell line stably expressing functional visualable hFcRn was established.基金项目:国家自然科学基金项目(“结构生物学指导的HBV治疗性抗体人源化及其关键技术研究”,No.31600748;“抗呼吸道合胞病毒高中和活性抗体的保护机制研究”,No.81401668;“基于广谱中和单抗的通用型流感疫苗设计及其结构基础研究”,No.31670934
