The semantic interpretation of determiner quantifiers and the relationship between syntactic structure and semantic structure of sentences with determiner quantifiers

根据Herburger(1997,2000),在阶段性谓词的语境中,处在限定量词内部论元位置的焦点对弱量化词而不是强量化词的语义解读有影响,而处在VP中的焦点对强量化词和弱量化词的语义解读都有影响。本文在此基础之上,进一步详细考察处在VP中的焦点对限定量词语义解读的影响;同时考察限定量词句的句法结构与语义结构的关系及其原因。本文认为,当焦点处在VP中时,全称限定量词实际难以对焦点敏感,其他限定量词对焦点敏感,但由于其比例解读和焦点解读的真值存在不同的蕴涵关系,使得其体现出的对VP内焦点的敏感性的强弱程度不同;限定量词句的语义结构在阶段性谓词的语境中受焦点影响而跟句法结构产生不一致关系,且这种不一致关系强弱量化词有别,原因在于阶段性谓词表示的具体场景中的具体事件,更容易成为参与者成分的标志而起到帮助辨识参与者的作用;弱量化词的强述谓性和强量化词的话题性,使得其内部论元位置的焦点成分在是否能移到LF层的VP中有别。Hcrburger （ 1997, 2000） observed that in contexts with stage-level predicates, focus in internal argument position of DQs has a truth-conditional effect on the interpretation of weak but not strong DQs, while focus in VP affects the interpretation of both weak and strong DQs. On the basis of Herburger （ 1997, 2000）, this paper aims to give a full picture of the way focus in VP influences the interpretation of weak and strong DQs, and based on the observations of the way focus in VP works, the paper tries to find out how and why syntactic structure and semantic structure are mismatched in sentences with DQs. It is pointed out that while universal quantifiers are insensitive to focus in VP, non- universal quantifiers are sensitive to it; the degree of focus-sensitivity of non-universal quantifiers varies from quantifier to quantifier, which is due to different entailing relation between the truth condition of their proportional reading （ where the restriction is provided by the internal NP） and that of their focus-affected reading （ where the restriction is provided by the non-focused part of the sentence）. The reason why focus has a structuring effect on semantic structure of DQ-sentences with stage-level predicates but not on that of DQ~sente~ce~ w~t~ ~,~dua~-~e,~e~ predicates ~,~e~ ~ t~e fact t~at t~e ~en~tati~n~ ~f stage~ level predicates are quite different from those of individual-level ones. What stage-level predicates denote are concrete events taking place in some specific temporal and spacial domain, while the denotations of individual-level ones are characteristics or properties that are relatively stable over time. As for why sentences with weak DQs allow for more mismatch between their syntactic structure and semantic structure than those with strong DQs, it is argued that weak DQ are of strong predicative properties and strong DQs are of strong topical properties and it is such a contrast that is responsible for whether the movement of a focused element in internal NP of the DQs to VP国家社科基金重大招标项目(项目批准号:12&ZD175)；国家社科基金一般项目(项目批准号:16BYY135)；教育部人文社科基金青年项目(项目批准号:13YJC740032)的资助

Economic Analysis on Catastrophe Insurance

长期以来，我国一直是一个巨灾事件多发的国家。巨灾不仅严重威胁着人们的生命和财产安全，还严重影响着经济发展和社会稳定。2008年5•12汶川大地震、2010年西南五省旱灾、青海玉树地震、甘肃舟曲特大泥石流等无不对我国经济和社会造成了巨大的冲击。在发达国家，由于风险保障水平较高，巨灾事故引发的庞大损失通常可通过保险、再保险等方式予以补偿；而在我国，就目前来看，由于保险业发展还处在起步阶段，商业保险还难以在巨灾发生时发挥重要作用。加上长期以来社会公众对灾后政府救助所形成的预期，导致每次巨灾发生时政府都不得不承担主要的损失。鉴于此，有必要在我国建立完善的巨灾风险管理体系，一方面降低巨灾事故...China has long been one of the countries that frequently suffered from catastrophe events.

联盟与多偶婚:作为政治范畴的媵妾制与巴力婚

基于葛兰言关于上古中国封建社会一夫多妻制的研究梳理,本文讨论了多偶婚研究在政治人类学中的价值意义。通过比较上古中国的媵妾制和古代阿拉伯的巴力婚这两种多偶婚形式所代表的两种联结社会的不同方式,可以看到群婚制的不同发展方向对于不同文明早期形态的形塑至为关键。在上古中国,\"华夏\"作为封建贵族联盟的\"通婚圈\",其形塑了上古中国社会的一种整体性,而贵族联姻的媵妾制则是维系这种等级性的联盟关系之产物。国家社会科学基金项目“马克斯·韦伯的宗教理论与蒙藏佛教社会的人类学研究”(项目编号:15BSH094);;国家民族事务委员会中青年英才培养计划项目“水利制度与中国边疆的封建类型:基于藏边诸社会的比较研究”(2016)阶段性成

在双促进铁催化剂上氨合成反应机理与动力学方程

本文从已知实验事实的理论分析,包括使用EHMO量子化近似计算及反应速率方程的推导等理论分析方法,提出了氮的活化、氢的活化、~(28)N_2—~(30)N_2同位素交换的机理.并提出氮的分子吸附以及H~(+δ)对吸附N_2~(-δ)作用生成NH_x是氨合成反应的二个决定性步骤.N_2~(-δ)与NH_x的相对含量决定于催化剂组成和反应条件(温度、压力、原料组成).文中根据微观分子催化作用机理,推导出相应的动力学方程式,该方程形式上与Temkin推广式一致,二者仅差一氢吸附常数项,但微观作用机理与某些动力学参数的物理意义则有重要的不同

Change about the Evolution of Financial Regulation in China:Mandatory or Induction

我国金融管制放松可归纳为银行业管制放松、利率管制放松、外汇管制放松、资本管制放松四个方面。我国金融管制放松主要是政府供给主导下的强制性制度变迁,同时伴有诱致性向强制性转变的制度变迁。金融管制放松的非均衡特征主要表现为管制放松的供给不足,管制放松的程度取决于预期净收益的大小。我国金融管制放松的路径依赖表现为政府主导下的渐进式强制性制度变迁。Chinese financial deregulation can be divided into banking deregulation,interest rate deregulation,foreign exchange control deregulation,capital control deregulation.Financial deregulation is the compulsory institutional change under the lead of government,accompanying with the system change that is from induction to mandatory.The non-equilibrium characteristic of financial regulation mainly embodies the lack of supply.The degree of deregulation is decided by the expected income.Path dependence of financial deregulation is characterized by gradual and compulsory institutional change under the lead of government

The Research on the Financial Accelerator of Monetary Policies under the Deregulation of Interest Rate in China

从我国货币政策执行情况以及宏观经济运行状况来看，货币政策往往是我国宏观经济波动的主要来源之一。那么，货币政策导致宏观经济波动是否由于货币政策存在金融加速器？本文分别基于企业、家庭和银行部门并结合我国利率管制放松进程研究我国货币政策金融加速器。 首先，建立理论模型分析金融加速器的产生机制，并应用回归分析和脉冲响应检验我国货币政策金融加速器，实证检验结果表明基于企业、家庭和银行部门的货币政策冲击存在金融加速器，并且利率冲击的金融加速器大于货币供给冲击的金融加速器。其次，应用门限回归模型分析我国货币政策金融加速器的非线性特征，实证结果证明了基于企业、家庭部门的利率、货币供给冲击的金融加速器具有非线...From the operating of monetary policies and the running of macroeconomy, it is clear that monetary policies are one of the sources of macroeconomics fluctuation.
