社会发展内涵探析

作为马克思主义哲学研究的社会发展，不是对具体的社会发展问题进行实证研究，而主要是运用逻辑手段，对复杂的社会发展现象进行抽象、概括，揭示出社会整体发展的普遍本质和一般规律。为了对社会发展有一个较为全面的理解，从社会、社会革命、社会变迁、社会转型与社会发展之间的关系入手进行了探讨。     

进化论思潮与唯物史观的传播——近代中国两大思想关系刍议

进化论思想与唯物史观同为近代中国影响广泛的思想。二者的传入时间接近，并且都经历了中国化的过程。随着进化论思想在现代遭到了越来越多的批判和质疑，唯物史观早期传播和发展的历程也经历了重新的审视。文章从近代思想史发展的事实出发，重新厘清两种思想的关系，并具体论证马克思的唯物史观能否从广义上归结为一种进化论的思想，以及进化论思想在中国是否经历了一个向唯物史观转变的历程。     

A New Methodology for Before–After Safety Assessment Using Survival Analysis and Longitudinal Data

The widely used empirical Bayes (EB) and full Bayes (FB) methods for before–after safety assessment are sometimes limited because of the extensive data needs from additional reference sites. To address this issue, this study proposes a novel before–after safety evaluation methodology based on survival analysis and longitudinal data as an alternative to the EB/FB method. A Bayesian survival analysis (SARE) model with a random effect term to address the unobserved heterogeneity across sites is developed. The proposed survival analysis method is validated through a simulation study before its application. Subsequently, the SARE model is developed in a case study to evaluate the safety effectiveness of a recent red‐light‐running photo enforcement program in New Jersey. As demonstrated in the simulation and the case study, the survival analysis can provide valid estimates using only data from treated sites, and thus its results will not be affected by the selection of defective or insufficient reference sites. In addition, the proposed approach can take into account the censored data generated due to the transition from the before period to the after period, which has not been previously explored in the literature. Using individual crashes as units of analysis, survival analysis can incorporate longitudinal covariates such as the traffic volume and weather variation, and thus can explicitly account for the potential temporal heterogeneity.     

Sex Related Factors in the Perception of Threatening Facial Expressions

This study replicated and extended previously reported sex differences involving both viewer and target in the recognition of threatening facial expressions. Based on the assumption that the evolved cognitive mechanisms mediating anger recognition would have been designed by natural selection to operate quickly in the interests of survival, brief tachistoscopic presentation of stimulus photographs was used. Additionally, in contrast to prior published studies, the statistical methods of signal detection research were used to control for the confounding effects of non-random guessing. The main hypothesis, that anger posed by males would be more accurately perceived than anger posed by females, was supported. A secondary hypothesis, that female-posed anger would be more accurately perceived by women than by men, received partial support. Testosterone levels, measured inferentially in terms of diurnal cycles, failed to show the hypothesized positive relationship to accuracy of anger perception.

在生物进化与人类进化之间

由于人类的进化已日益集中反映在文化的进化上 ,从而使得它与生物之间表现出不同的性质和方式。对于属人世界的生物进化来说 ,既存在自然选择式的客体中介 ,又存在社会选择式的主体中介 ,在当今世界所普遍存在的“生态危机”和各种“人类危机”面前 ,我们更需要确立和谐型的社会选择     

论资本市场全球一体化趋势

资本市场全球一体化是当前全球资本市场发展的基本趋势。是指相对独立的全球各主要资本市场日益融合形成的统一市场网络组织结构体系。表现为市场组织形式的全球网络化 ;筹资主体的国际化 ;投资者的机构化及投资活动的国际化 ;资本流动的全球化 ;同质的金融资产价格趋同化 ;金融机构经营业务的混业化和全球化。资本市场全球一体化降低了市场主体的交易成本 ,提高了市场效率 ;为一些国家调节国际收支失衡与国际储备的保值增值提供了便利条件 ;有利于长期资本的优化配置 ,促进世界经济增长。同时也使各国运用货币政策调控宏观经济的有效性降低 ;市场的系统性风险增大 ;金融监管面临新的挑战     

走向西方的日本近代文学的起点——进化论与坪内逍遥的小说改良

由于明治以来的日本文化始终处于东西方文化交融的前哨 ,研究日本近代文学也必须从东西文化交融这一点切入。明治文学的起点是坪内逍遥的小说改良 ,其小说改良的理论基础是进化论。但对于进化论如何影响日本近代文学的确立这一问题若明若暗 ,如今 ,在日本文学界成为反思的一个焦点 ;同样 ,对这一问题的探讨也有助于对我国现当代文学的理论研究
