    信息披露制度是世界各国证券法确立的一项重要制度,是推动证券市场发展、投资者保护的基础性制度。“重大性”标准是信息披露制度的基础性制度之一,并且贯穿信息披露的始终。在我国竭力推行证券市场改革的当下,需要补充完善上市公司信息披露的“重大性”标准,避免证券市场充斥过多的噪音,使投资者陷入众多细小琐碎却无关紧要的信息之中。 第一章探讨信息披露制度“重大性”标准的基础理论问题。首先分析“重大性”标准的内涵及与之相关的学说制度,“重大性”标准与信息披露制度其他标准之间的关系。其次提出当前研究信息披露制度“重大性”标准的价值。 第二章研究当前我国信息披露制度下的“重大性”标准。首先从法律法规和自律规则两...Information disclosure lays a solid foundation for the security management.

    1994年起实施的分税制改革从根本上扭转了中央财力的困窘局面,逐渐形成了财力中央集权、事权地方分权的局面。基础教育作为地方政府所需提供的主要基本公共物品之一,在前农村税费改革时代是靠预算内资金和预算外资金共同支持的。然而,21世纪初开始中国逐渐在农村推开税费改革,在很大程度上重塑了基层公共物品的供给模式。对于基础教育而言,就是从实际上的“乡办教育”变成“以县为主”的供给模式。在此次改革中,因“三提五统”资金的废除而被压缩了预算外部分,加上比改革前损失的农业税和农业特产税收入减少了预算内部分,农村基础教育资金缺口仅仅靠县级财政已经难以为继。在此背景下,作为补偿手段的上级转移支付就呼之欲出了,中央...Since the tax sharing system (TSS) reform in 1994, the embarrassing situation of central financial resources has been fundamentally reversed, which gradually turns into a “resource-up and responsibility-down” model. As one of the most important public goods provided by the local governments, basic education was supported by budgetary and extra-budgetary funds together before the agriculture tax re...学位:法学硕士院系专业:公共事务学院_政治学理论学号:1382011115056

    与传统的微粒制备方法(如机械粉碎与研磨、溶液结晶、化学反应等)相比,超临界流体微粒化技术具有产品纯度高、几何形状均一、粒径分布窄、制造工艺简单、操作适中等许多优点,尤其对热敏感、结构不稳定和具有生物活性的物系的处理具有明显优势。超临界流体抗溶剂-雾化SAS-A(SupercriticalAnti-SolventAtomization,SAS-A)技术以PGSS和SEDS技术为基础,综合了PGSS和SEDS的优点,适合于处理含水体系。本文介绍一套自行设计及搭建的SAS-A实验装置,以该技术研究制备高分子、蛋白质微粒,以及它们的复合微粒;探讨压力、溶液流量和溶液浓度等工艺参数对形成的微粒粒径、粒径...Microparticles with narrow particle size distributions are widely used in many fields, such as biochemistry, materials, pharmaceuticals, cosmetics, etc., due to their excellent chemical properties and physical effects.

    塑造正统:北魏太庙制度的构建

    Get PDF
    在塑造华夏正统过程中,北魏太庙制度的构建在胡汉问题、南北正朔之争、皇权等因素主导下,呈现出较为复杂的历史层面。北魏前期先祖祭祀以东庙为主,至孝文帝改革先祖祭祀制度,太庙祭祀的地位始得以凸显,彰显出北魏先祖祭祀由胡汉杂糅走向以华夏制度为主导的历史转变。北魏太庙制度的构建经历了孝文帝之前"天子七庙"的形成以及孝文帝以后太庙制度的确立两个阶段。中古时期宗庙制度的构建在经学理论上主要以郑、王礼说为依托,两晋南朝宗庙制度采用王肃学说,而道武帝所立太庙,分置始祖、太祖,具有缘饰经典及郑玄学说的明显迹象。此后在学说的择从上,北魏太庙制度的构建呈现出由兼采郑玄、王肃学说到全遵郑玄学说的趋势,并在孝明帝时期最终确立相对完备的宗庙制度。北魏以承继西晋自居,而在太庙制度的构建上,并未依从两晋南朝之制,显现出与东晋南朝争正统的态势。中国社会科学杂志社《历史研究》编辑部与上海师范大学人文与传播学院主办的第四届青年史学家论坛论文;为国家社科基金重大项目“中国礼制变迁及其现代价值研究”(12&ZD134)阶段性成果

    《国史儒林传》与阮元《儒林传稿》关系辨误

    Get PDF
    前人所论《国史儒林传》与阮元《儒林传稿》关系,多沿袭缪荃孙《国史儒林文苑两传始末》之说,以为顾莼任国史馆提调,改定阮元《儒林传稿》,以顾炎武居首位,而后国史馆总裁戴衢亨又增删《儒林传稿》。今勘验其实,知缪说不足尽信。从目前相关史料言之,顾莼在阮元任国史馆总裁之际,出任国史馆纂修官,拟定顾炎武传初稿,后经阮元审定收入《儒林传稿》,以顾栋高居首,并无顾莼修改《儒林传稿》之事;增删《儒林传稿》之总裁乃曹振镛,而非戴衢亨。阮元《儒林传稿》初经曹振镛、翁方纲厘定其篇目,道光二十四年方俊、蔡宗茂复加改定,今《国史儒林传》以方、蔡改订本为底本,但编次又有异

    董棕为棕榈科鱼尾葵属常绿乔木,它是我国稀有大型棕榈植物,自然资源少,主要生于海拔370-2000m处的山坡和沟谷中,是国家二级保护濒危种。本文通过ISSR分析了董棕的遗传多样性并借助对叶绿体trnK基因的内含子matK序列分析,初步研究了中国原生鱼尾葵属4种属间的系统发生。 从董棕新鲜叶片中采用CTAB法摸索和提取董棕叶片基因组DNA,找出最合适的提取条件和药剂用量。在此基础上,对董棕ISSR-PCR进行扩增,从100条ISSR引物中筛选出可以扩增出清晰、重复性好的15条带的引物,15条引物对109份材料共扩增出163条带,扩增条带分子量大小在0.1-2kb之间,其中156条带具有多态性,其...Caryota urens Linn. is often green the tree, it is our country rare large-scale palm plant, the natural resource are few, mainly had been born in the elevation 370-2000m place hillside and the run-off ditch.It is the national two levels of protections is in imminent danger plants.Sequence research preliminary analysis China primary Caryota has been 4 kinds through chloroplast trnK the gene content...学位:理学硕士院系专业:生命科学学院生物学系_发育生物学学号:2172006115217

    隋唐圜丘三壝形制及燎坛方位探微

    一、问题缘起郊天礼作为中国古代皇帝祭天的重要礼仪,在汉魏以后国家祭祀中居于主导地位。商周时期是否已确立南北郊祀制度,不易确知[1],《春秋》书郊者凡九,学者以为“郊为夏正正月祈谷之礼”。在秦汉国家祭祀整合过程中,西汉末年王莽所定“元始仪”开启了汉魏以后国家郊祀制度之先河。在汉唐之间,以是否建立圜丘,郊天制度存在两种情况。The excavation to the yuanqiu (Circular Mound Altar) of the Sui and Tang Dynasties at the Tang Chang' an City roughly made clear the forms of the altar body and the neiwei (inner enclosure wall). The contents about the .yuanqiu of the Sui and Tang Dynasties in the historic literatures of the Tang and Song Dynasties are helpful for us to clarify the forms of the sanwei (three enclosure walls of the yuanqiu) and the location of the liao-burning sacrifice altar. In the early Northern Song Dynasty, the forms of the yuanqiu and sanwei followed that of the Tang Dynasty; by referring to the relevant historic literature of the Song Dynasty, the sizes of the yuanqiu and sanwei of the Sui and Tang Dynasties could be understood and the exact location of the liao-burning sacrifice altar in Da Tang Kaiyuan Li (Ritual of the Kaiyuan Era of the Great Tang) could be accurately confirmed. The yuanqiu of the Sui and Tang Dynasties has been amended for many times, but the general forms of the altar and enclosure walls were almost unchanged. The location of the liao-buming sacrifice altar in the Zhenguan Xin Li (New Ritual of Zhenguan Era) and Da Tang Kaiyuan Li has altered, but was not moved beyond the basic rule for the location of liao-burning sacrifice altars in the southern suburb of the capital of the Han to the Tang Dynasties.国家社科基金重点项目“《大唐开元礼》校勘整理与研究”(编号:15AZS001)的阶段性成果
