Distortions of Asymptotic Confidence Size in Locally Misspecified Moment Inequality Models

This paper studies the behavior, under local misspecification, of several confidence sets (CSs) commonly used in the literature on inference in moment (in)equality models. We propose the amount of asymptotic confidence size distortion as a criterion to choose among competing inference methods. This criterion is then applied to compare across test statistics and critical values employed in the construction of CSs. We find two important results under weak assumptions. First, we show that CSs based on subsampling and generalized moment selection (Andrews and Soares (2010)) suffer from the same degree of asymptotic confidence size distortion, despite the fact that asymptotically the latter can lead to CSs with strictly smaller expected volume under correct model specification. Second, we show that the asymptotic confidence size of CSs based on the quasi‐likelihood ratio test statistic can be an arbitrary small fraction of the asymptotic confidence size of CSs based on the modified method of moments test statistic.     

The role of cognitive distortion in online game addiction among Chinese adolescents

The aim of the present study was to examine the role of cognitive distortions in the development of on-line game addiction among Chinese adolescents. In Study 1, the sample comprised 495 adolescents aged 12 to 19 who recruited from two middle schools in Guangzhou, China. They were administered questionnaires relating background variables, the Internet Addiction Scale (IAS), Cognitive Distortions Scale (CDS) and Online Game Cognitive Addiction Scale (OGCAS). In Study 2, Twenty eight adolescents with excessive on-line game play recruited from a local mental hospital were randomly divided into to a CBT group (N = 14) and a clinical control group (N = 14). Measures of severity of on-line game playing, anxiety, depression, and cognitive distortions were assessed on baseline and after the 6 week intervention. Results of the present study showed that rumination and short-term thinking were the most predictors of online game addiction, and all-or-nothing thinking predict online game addiction at marginal significant levels. Males are at a greater risk of developing online game addiction than do females. CBT and basic counseling had different treatment effects on the all-or-nothing thinking scores, online comfort scores and short-term thinking scores, SDS scores and SAS scores. Interestingly, CBT and basic counseling had similar treatment effects on IAS scores and OGCAS scores. Applications of these findings to etiological research and clinical treatment programs are discussed.     

金融时间序列的标度特性实证研究

分别从时间序列分析,简单分形分析及多重分形分析的角度,运用自相关、功率谱、盒维数以及多重分形谱方法对上证指数时间序列的标度特征进行了实证研究.首先,自相关函数和功率谱分析结果表明.上证指数时间序列在跨时间尺度的指教之间存在着相关性,表现为分形时问序列,说明市场未达到弱式有效;其次,盒维数的分析结果揭示了上证指数的聚类特征及标度变化,并且盒维数随临界值增加而递减的规律体现了多标度特征的存在;最后,多重分形谱的方法进一步确认了上海股票市场的多标度特性,并指出该特性是股票市场信息倍增级联过程的结果.     

《尘埃落定》中的原型塑造

“文本”的创造与“原型”的转换，始终都存在着一种隔不断的互动联接，直到“文本”以独立的存在形式面世。民间原型的运用使得《尘埃落定》体现出巨量的人类学的价值。借助民间原型批评理论分析了生殖崇拜与成人仪式、圆形循环与天命难违、洪水神话与征兆等几组民间原型在《尘埃落定》中的置换变形和巧妙结合，从而为阐释这部作品找到一种“元语言”。     

我国会计师事务所的性质与功能扭曲的管制

通过对会计师事务所参与企业会计造假及提供企业虚假财务审计信息的分析,在纵观国内外会计师事务所的性质、形成与发展的基础上,剖析了会计师事务所在社会经济事务中发挥的弥补市场失灵与政府失灵的基本社会功能,并从会计信息失真与会计师事务所之间的经济利益关系,揭示了会计师事务所提供虚假财务审计信息、参与企业会计造假的原因及其社会危害,进而提出了管制会计师事务所行为扭曲的政策措施与建议。     

民生忧痛的史诗,社会苦难的画卷--蒋牧良小说思想内容探微

在宏阔的时代背景下,湘中作家蒋牧良清醒地审视了自己脚下的土地,深情凝眸于故土家园,他的作品深广地反映民生忧痛,揭示社会黑暗.本文力图从揭露残酷的阶级压迫、展示黑暗的社会现实,反映人性的变形扭曲,呼唤人们的觉醒反抗等四个方面对蒋牧良小说的思想内容作一浅析.     

计提资产减值准备对会计信息失真的影响

《企业会计制度》要求企业计提八项减值准备,以降低企业的潜在风险。制度实施的本意是好的,但由于《企业会计制度》自身的原因,使实务操作具有较大的可选择空间,因此,在一定程度上为会计信息失真提供了温床,这是客观存在的,也是影响程度较大的。本文着重从制度的可选择性论述其对会计信息的影响。     

蜗壳进口周向非均匀流动的一种迭代计算方法

提出了通过叶轮与蜗壳 工计算来求解蜗壳内流场的方法，该方法边界条件处理简单，并能在并不增加很多计算量的基础上模拟出蜗壳进口周向流动的非均匀性，从而突破了在计算单个蜗壳时，其进口只能给均匀边界条件的局限性，通过对一蜗壳的试算结果表明，在设计工况下，蜗壳进口周向流动比较均匀，而在变工况下，特别在蜗舌附近，流动的非均匀性要强烈得多。     

浅谈我国会计信息违法性失真的成因及治理对策

会计信息失真通常包括会计信息规则性失真、会计信息违法性失真、会计信息技术性失真。文章从违法性的角度分析了会计信息失真的原因并提出了治理会计信息违法性失真的对策。     

会计信息失真中会计人员民事责任研究

会计信息监管对于解决代理人履行受托责任中的道德风险，以及解决信息不对称的问题具有重要意义。要保障会计信息的质量，会计师本身必须遵守其职业规则和证券法律。美国证券法制定了完善的会计师民事责任条款，以惩罚或制止会计人员的违法行为，对我国证券法的完善具有一定借鉴意义。
