    扬州依托四通八达的水系交通,成为唐代江淮地区盐、粮、茶大宗货物的转运中心,对大宗货物的转运业务也就成为扬州的经济支柱。“扬一益二”的历史评价,说明了扬州经济水平的发达状况以及其在唐代中后期的经济地位。在唐代中后期,政府对大宗货物的经济管理政策发生巨大变化,从经济管理者转变为参与者,扬州罗城也经历了从无到有的过程,但是罗城内不设坊墙,将市设在城的南端,远离人口密集之处,其中原因值得深入探讨。 通过梳理都城历史,观察坊、市在城内分布区域的变化,推断唐政府采取封闭式的空间格局、严格的交易时间管理为特点的坊市分离制度,在唐初是有利于商业发展的。而唐政府采用坊市分离制度更多的是对历史的沿袭而非故意限制...Yangzhou relying on accessible water traffic,become the southeast of the Tang Dynasty salt, grain, tea bulk cargo transit center.

    陈墨香是民国时期著名的京剧票友、编剧家以及戏曲批评家。他的戏曲理论批评和研究注重从艺术本体出发,对京剧进行整体性的研究和论述,并提出一些颇具创建性的主张和观点。他注意到京剧艺术厚重的民间文化底蕴,有意识地对京剧表演与民间习俗的互动关系进行考察,拓宽了京剧学的研究路径。陈墨香的京剧研究以丰赡的戏曲活动经验为支撑,虽然经验描述多于理论阐发,未能形成严整的理论体系,但他的京剧批评和研究,对于二十世纪的戏曲理论批评乃至今天的京剧研究都具有重要的参考价值和意义。 本文以陈墨香的京剧学研究著述为对象,在对原始资料进行归纳、总结的基础上,结合前人的研究成果,对陈墨香的京剧学研究进行深入的分析和研究,以期全...Chen Moxiang was famous as an amateur performer of Peking Opera, scenarist and drama critic in the period of Republic of China.

    Fission life-time calculation using a complex absorbing potential

    Full text link
    A comparison between the semi-classical approximation and the full quantum calculation with a complex absorbing potential is made with a model of the fission of 258Fm. The potential barrier is obtained with the constrained Skyrme HF+BCS theory. The life-time obtained by the two calculations agree with each other the difference being only by 25%.Comment: 5 pages, 2 figures, Conference proceedings of CNR*15 workshop, Tokyo, October 2015 to be published in EPJ Web of Conference

    Research and Application of Classifier with Confidence

    高风险领域的分类问题对模式分类算法提出以下三个挑战: 1)能否设计一种分类器模型,使得它的输出结果能够附带置信度; 2)预测输出的置信度是有效的,应该使得算法的准确率能够被置信度所控制。 3)算法应能够独立地对每个测试数据提供相应的置信度评估,也就是说,能够根据指定的置信度产生相应的预测结果。 针对上述三个挑战,我们引入了基于转导推理和随机性检验的置信预测方法来解决这些问题。近年新发展起来的一致性预测器(CP)是这种方法的典型代表。但是,CP在实践中的实用性较差,主要是其固有的运算效率低下、以及对样本奇异函数的设计缺乏指导性准则。我们的工作主要是改进了CP的理论模型,提出了混合压缩一致...There are three challenges to the researchers on the classification in the high-risk areas: 1)Can we develop a classification algorithm that outputs predictions coupled with confidence level? 2)Are these confidences for the predictions really valid, i.e., could the accuracy rate be guaranteed by the confidence level? 3)Could the algorithm give a prediction with a confidence level tailored for ...学位:工学博士院系专业:信息科学与技术学院自动化系_控制理论与控制工程学号:2322006015338

    摘要经济全球化的今天,市场竞争已从企业发展战略向产业集群战略演化。产业集群作为区域经济发展的重要组织形式,不仅极大地推进了区域经济发展,而且增强了区域产业在国内乃至国际上的竞争优势,越来越成为区域参与国际经济竞争的一支重要的新生力量,日益受到国内乃至世界范围内的关注。无论是发达国家还是发展中国家,纷纷实施产业集群战略,力求形成具有高度竞争力的企业集聚区,从而增强一个地区乃至一个国家的竞争优势。福建作为对外开放和海峡两岸交流合作的前沿阵地,如何打造个性化发展之路,成为摆在区域经济发展决策者面前的重大任务。这几年,福建省委、省政府把加快产业集聚、培育发展产业集群作为福建建设海峡西岸经济区的六大举措...Abstract On the background of economic globalization, market competition has evolved from business development strategy to industrial clusters strategy.

    The Effect of Ownership Structure on Cash Dividend Behavior in Chinese Listed Companies

    从1956年Lintner[1]对公司最佳股利政策的研究开始,现金股利一直是现代财务理论研究的一个重要领域。理论与实证研究成果证明,不同地区不同阶段的现金股利分配都会有不同的特点,学者们将这一普遍现象定义为“现金股利之谜”。在国外的研究中,现金股利作为一种减少代理成本的方式被投资者所青睐,而在我国,基于上市公司股权结构集中度高和股权分置的特殊背景,现金股利成为大股东对小股东利益进行侵害的工具,出现了分与不分都会损害小股东利益的尴尬局面,即“现金股利悖论”。 截至2006年底,我国的股权分置改革已基本完成,股改对于公司现金股利分配的影响尚不确定。本文以我国特殊的股权集中和股权分置改革为背景,从...Cash dividend policy has always been a widely addressed topic in modern financial literature, since the research of Lintner in 1956 on the best dividend policy. Both theoretical and empirical study indicates that cash dividends in different areas and stages will have different characteristics, which is called “the cash dividend puzzle”. In the research abroad, cash dividends are favored by investo...学位:管理学硕士院系专业:管理学院会计系_会计学学号:1752008115132
