黑洞热力学第三定律与宇宙监督假设

对黑洞视界的研究结果表明 :黑洞热力学第三定律可禁止裸奇性的出现 ;反之 ,裸奇性的出现必破坏黑洞热力学第三定律。由此推断宇宙监督假设就是黑洞热力学第三定律。     

语用预设--美国2000年总统大选辩论片断分析

语用预设作为句子或话语中隐含的信息或命题，对交际双方的话语理解起着至关重要的作用。本以美国2000年总统大选辩论为语料，试运用语用预设这一话语中的隐含信息为理论指导分析辩论双方是如何阐述自己的政见，以及对对方的政纲提出质疑，批评和攻击，以捞取政治积分并赢得选民的支持。通过分析，章旨在揭示语用预设理论能更好的帮助我们理解政治体裁章，并为各种语篇分析带来新的启示。     

西方企业反收购的经验和启示

西方企业的反收购措施的部署大致可分为两类：预防性和主动性的。预防性的措施是为了减少财务上成功的敌意收购的可能性，而主动性的措施在敌意报价后采取。我国企业的反收购尚处于起步阶段，反收购体系不完善，我们可以借鉴西方企业成熟的反收购策略，进行一定程度的变异，移植到我国特有的国情中。     

Cross-Racial Friendships and Social Distance Between Racial Groups on a College Campus

This study examined the effectiveness of curriculum-focused diversity initiatives on a college campus by determining the relationships between GPA, social class, year in school, residential status, racial diversity courses taken, and cross-racial friendships on the level of social distance between Whites-Blacks, Whites-Hispanics, Hispanics-Whites, Hispanics-Blacks, Blacks-Whites, and Blacks-Hispanics. The data suggest that, while the institution does a good job of bringing diverse groups of students to the campus, it does not effectively reduce the level of social distance among many members of the different racial groups on campus. Using the Intergroup Contact Hypothesis, the article concludes by suggesting means by which social distance among racial groups on campus might be decreased.     

数学教学中非智力因素培养途径及其有效性检验

本文针对数学教学的实际特点, 分别从成就动机、认识兴趣、学习毅力和注意稳定性四个方面研究了数学教学中非智力因素培养的各种切实可行的方法与途径。以惠州学院数学系数学教学为例本文进行了实证研究, 包括学生非智力因素状况调查与培养途径有效性检验。结果表明, 目前学生非智力因素状况总体良好, 却存在诸多问题; 学习兴趣对数学成绩的影响极其显著, 而注意稳定性和意志力对数学成绩直接影响不显著。     

圆柱滚子轴承的强度研究

依据赫兹接触强度计算理论,着重研究了圆柱滚子轴承内、外圈及滚动体的接触应力。结果表明,当内圈与滚动体运动到与轴承所受经向载荷方向重合时,内圈与滚动体之间的接触应力最大。     

Discrete Time Survival Analysis Via Latent Variable Modeling: A Note on Lagged Depression Links to Stroke in Middle and Late Life

This article is concerned with a latent variable modeling approach to discrete time survival analysis that includes both time-invariant and time-varying covariates. The approach is illustrated with data from the Health and Retirement Study, which are utilized to study further the relationship of depression to stroke in middle and late life. Employing lag-1 depression scores as time-varying covariates, in addition to a set of relevant medical and demographic variables as time-invariant covariates collected at baseline, the article addresses a particular aspect of the prominent vascular depression hypothesis representing an important area in aging research, gerontology, geriatrics, and medicine. The results indicate considerable links of immediately prior depression levels to subsequent occurrences of stroke in middle-aged and older adults. The findings complement those reported by Raykov, Gorelick, Zajacova, and Marcoulides (2017), and are consistent with that hypothesis implying depression as a potential warning sign of an impending stroke.     

我国利率期限结构预期假设的实证研究

从长期利率的短期变化和短期利率的长期变化两个角度提出利率期限结构预期假设检验的理论框架,并对我国市场进行了实证检验。检验基于Nelson-Siegel扩展模型估计的几个主要期限的利率。在实证检验前,对利率时间序列的平稳性进行了分析。在实证检验中,考虑了抽样间隔和预测间隔不一致而导致的数据重合问题。检验结果表明,我国利率期限结构的预期假设检验出现了“预期迷惑”现象,我国长期利率对市场冲击发生过度反应,利率期限结构预期假设不成立。     

再论继承与创新--兼析中国画现代与传统之争

20世纪的中国画界,继承与创新、传统与现代之间演绎了一场唇枪舌战。而其实,矛盾双方的争论其实围绕的是一个假设命题,急功近利和保守退却同是艺术和中国画的大敌,而现代中国画丰硕的成果恰恰得益于不可缺一的二者：优秀的传统遗产和现代文明最前沿的成就。     

竞争力度量的一种新假说——基于结构主义方法论的研究

针对"竞争力内涵与度量尚未形成统一认识"的问题,通过梳理国际知名学者与组织的相关研究成果,总结出竞争力度量的共性指标;在此基础上,运用结构主义方法论的研究思想,将竞争力与牛顿力学和量子力学进行类比后,针对经济竞争的三种方式,将力学中的动量定理理论推广到经济管理领域,提出了竞争力度量新假说。最后,运用该理论对我国省域建筑产业竞争力进行了实证研究。
