《子夜》中"自我分裂"的空间意象世界

从空间视角切入 ,小说《子夜》中的上海可以被解读为一个意象化的空间世界。由都市上海、吴公馆和主人公吴荪甫的私人书房等几个重要的空间意象 (群 )构成的这个开放性的空间系统 ,在不同人物的不断参与和介入中被改写 ,并由此呈现出鲜明的自我分裂特质。以吴荪甫为中心建立起来的空间意象世界的最终崩溃 ,可以看出茅盾着意表现的 30年代初上海民族工业必然失败的多重原因。     

A股上市首日超额收益影响因素的实证研究

在股权分置改革的背景下,运用多元线性回归模型的加权最小二乘法,对2004年1月1日至2007年12月31日期间发行上市的206只A股的实证研究,发现上市首日股票换手率、筹资规模和市场指数对上市首日超额涨幅具有较显著的影响;而发行价格、发行市盈率、发行前每股净资产、发行后实际流通股比例、发行方式及股权分置改革对A股上市首日超额收益影响不显著。     

Interval Partitioning Arising from Size-Biased Picking

We consider the following fragmentation model of the unit interval 𝕀. We start fragmenting 𝕀 into two pieces with uniform random sizes. One of these two subintervals is then chosen at random according to a β-size-biased picking procedure, β ∈ ?. This particular tagged fragment is next broken into two random pieces, one of which is chosen accordingly at random for further splitting; the process is then iterated independently. This model constitutes a recursive β-partitioning procedure where splitting occurs only at one of the two fragments formed in the previous step of fragmentation. We investigate some statistical features of this model.     

等待克拉普——试论戏剧《最后的磁带》对自我的追寻

主体的问题是现代社会大多数急迫问题的核心。自弗洛伊德以来,很多理论家都阐述了主体的分裂和虚构性。戏剧无疑是最适合表现这一主题的艺术形式。相比之下,爱尔兰剧作家赛缪尔.贝克特对这一主题的探索更加执著和持久。贝克特塑造的分裂的人物不仅对传统的戏剧审美观提出了挑战,而且以一种全新的角度来展现现实世界。在《最后的磁带》中,贝克特运用录音机,以39岁的这盘磁带作为一个交汇点,让29岁、39岁和69岁的克拉普通过录音机讲述自己,以克拉普的三段人生并置和相互参照,来探索自我的稳定性、真实性和进步性。     

人性的分裂性变化——《高兴》与《了不起的盖茨比》人物形象比较研究

《高兴》与《了不起的盖茨比》分别是中国作家贾平凹与美国作家菲茨杰拉德的重要作品。尽管两位作家来自不同的文化与社会背景,但他们在各自的作品中都突出表现了消费文化对整个社会的穿透力,揭示了社会大众在消费文化的示范下人格的扭曲与行为的失常,展示了一幅社会转型时期东西方社会所呈现出来的共同画面:财富与精神的疏离、信仰与道德的缺失。     

对股权分置改革对价问题的市场分析——通过股权分置改革试点阶段G股的市场表现认识对价的特征

股权分置改革作为一场促进我国资本市场健康发展的制度性变革,给股市带来了生机,G股的活跃表现为投资者创造了更多的投资机会。在股权分置改革试点阶段,试点企业推出的对价方案呈现出对价方式的多样性、对价水平的差异性、对价依据的非统一性和调整对价的随意性等多种市场特征。对价方式的多样性为投资者提供了更多的市场机会,对价水平的高低差异反映了不同的对价成本,对价依据的差异性是导致不同对价水平的主要原因,上市公司频繁调整对价方案缘于非流通股股东与流通股股东的沟通和交流。     

中国法院对重整计划强制批准的问题与解决

法院对重整计划的强制批准是破产法中的核心法律制度,“供给侧结构性改革”推动了法院对重整计划强制批准的司法适用。中国法院对这一“舶来”法律制度的司法适用存在诸多问题:严重的社会本位主义、盲目过高的适用比例、与正常批准的关系颠倒、缺乏全面的审查规定、对普通债权人的保护不利等。要回归法院强制批准正确的司法功能,确保中国法院对重整计划强制批准的正当适用,就必须借鉴《联合国破产法立法指南》及域外的立法,结合2018年最高院《破产审判会议纪要》“审慎适用”规定,从理论、立法和司法层面寻求对问题的解决途径包括充分认识法院强制批准权力的属性、正确定位正常批准和强制批准的关系、修订完善强制批准的实体审查条件、合理构建强制批准的审查程序等。法院对重整计划强制批准问题的解决有助于中国《企业破产法》的修订完善。     

On the Discrete Version of the Aumann–Shapley Cost‐Sharing Method

Each agent in a finite set requests an integer quantity of an idiosyncratic good; the resulting total cost must be shared among the participating agents. The Aumann–Shapley prices are given by the Shapley value of the game where each unit of each good is regarded as a distinct player. The Aumann–Shapley cost‐sharing method charges to an agent the sum of the prices attached to the units she consumes. We show that this method is characterized by the two standard axioms of Additivity and Dummy, and the property of No Merging or Splitting: agents never find it profitable to split or to merge their consumptions. We offer a variant of this result using the No Reshuffling condition: the total cost share paid by a group of agents who consume perfectly substitutable goods depends only on their aggregate consumption. We extend this characterization to the case where agents are allowed to consume bundles of goods.     

Inference after variable selection using restricted permutation methods

When confronted with multiple covariates and a response variable, analysts sometimes apply a variable‐selection algorithm to the covariate‐response data to identify a subset of covariates potentially associated with the response, and then wish to make inferences about parameters in a model for the marginal association between the selected covariates and the response. If an independent data set were available, the parameters of interest could be estimated by using standard inference methods to fit the postulated marginal model to the independent data set. However, when applied to the same data set used by the variable selector, standard (“naive”) methods can lead to distorted inferences. The authors develop testing and interval estimation methods for parameters reflecting the marginal association between the selected covariates and response variable, based on the same data set used for variable selection. They provide theoretical justification for the proposed methods, present results to guide their implementation, and use simulations to assess and compare their performance to a sample‐splitting approach. The methods are illustrated with data from a recent AIDS study. The Canadian Journal of Statistics 37: 625–644; 2009 © 2009 Statistical Society of Canada     

对股权分置改革现实意义的思考

中国股市因为特殊的历史原因而存在流通股和非流通股两类股票,同股不同权、同股不同价、同股不同利的弊端制约着我国证券市场的进一步发展。从减持国有股到全流通问题,再到解决股权分置问题,反映了对证券市场的认识不断深化的过程。股权分置改革是资本市场的一项重要制度改革,不仅有利于完善资本市场定价机制,强化对上市公司的市场约束,充分发挥资本市场的功能和作用,还有利于国有企业的改造重组和国有经济布局的战略调整,关系到投资者的切身利益和上市公司的长远发展。
