严羽和戴复古身世行迹诸问题考——对《严羽评传》的几点商榷性意见

严羽和戴复古订交的时间在绍定五年 (12 32 )而非嘉定十四年 (12 2 1) ;严羽避乱返乡时间在绍定四年而非元年 ;严羽的《平寇颂》写于端平元年 (12 34 )五月之后而非绍定三年间 ;戴复古布衣一生 ,并未任过邵武军学教授     

“九·一八”事变与“满洲国”的建立

日本自明治维新后,制订了称霸亚洲和世界的"大陆政策",其核心是"满蒙"政策.日本在基本实现"大陆政策"的第一期侵略目标(吞并朝鲜)后,立即着手为实现第二期侵略目标(独占"满蒙")进行各种准备."九·一八事变"和伪"满洲国"的建立,标志着日本大陆政策第二期目标的基本实现.事变的结果,不仅使日本实现了既定的侵略目标,而且又以"满洲"为基地,准备实现第三期侵略目标,即征服全中国乃至称霸亚洲.     

山海关士绅与山海关之变--一组甲申山海关之变新史料的发现及意义

山海关地方史志里的一组史料表明,山海关当地士绅在甲申山海关之变中起了极为恶劣的作用他们鼓动吴三桂"降清灭闯",勾结清兵入关,阻挠李自成进军山海关.这些活动在一定程度上促成了山海关之变的结局.     

Evaluation of strategies to mitigate contagion spread using social network characteristics

Computer simulation is an effective tool for assessing mitigation strategies, with recent trends concentrating on agent-based techniques. These methods require high computational efforts in order to simulate enough scenarios for statistical significance. The population individuals and their contacts determined by agent-based simulations form a social network. For some network structures it is possible to gain high accuracy estimates of contagion spread based on the connection structure of the network, an idea that is utilized in this work. A representative social network constructed from the 2006 census of the Greater Toronto Area (Ontario, Canada) of 5 million individuals in 1.8 million households is used to demonstrate the efficacy of our approach. We examine the effects of six mitigation strategies with respect to their ability to contain disease spread as indicated by pre- and post-vaccination reproduction numbers, mean local clustering coefficients and degree distributions. One outcome of the analysis provides evidence supporting the design of mitigation strategies that aim to fragment the population into similarly sized components. While our analysis is framed in the context of pandemic disease spread, the approach is applicable to any contagion such as computer viruses, rumours, social trends, and so on.     

富田事变研究述评

THE CHOICE BETWEEN SETS OF REGRESSORS

This paper examines the choice of critical values for testing both non-sequential and nested sequential sets of constraints in the standard linear regression model. Modest increases in (e.g.) t-ratio critical values relative to their one-off values are often sufficient to maintain proper size. A Bayesian decision-theoretic approach, highlighted by the Schwarz (1978) criterion, provides a framework for deriving consistency and asymptotic local power properties of both forms of testing (data mining) algorithms.     

THE FUTURE OF PUBLIC MEDIA CULTURES

This paper seeks to tie in the arguments that can be connected to the development of a global media culture and concerns around cosmopolitan forms of democracy. This is done by considering arguments for: (i) a global human right initiative in respect of global media conglomerates; (ii) technological change in respect of digital cultures; and (iii) the arrival of what Castells'shas described as the culture of 'real virtuality'. These views and perspectives are assessed in terms of the contributions they are likely to make towards what I call a 'cautious cosmopolitanism'. Finally I seek to make some definite policy recommendations that might help foster conditions in which cosmopolitan democracy could flourish.     

心理活动脑机制的研究历程及研究技术的新进展

本文阐述了心理活动的脑机制及其研究技术的发展过程,从而客观地表达了两种观点:一是,计算机辅助成像技术已成为人类心理活动脑机制研究的新技术;二是,人类的心理和行为活动在大脑皮层都有相应的机能定位,这种机能定位不是绝对的、机械的,而是在整体机能上的动态定位。     

试析狭义批判性思维

狭义批判性思维是对信息试图否定的思维方法,其逻辑机制包括否定、否定的否定、否定与肯定的辨证统一三种情况。批判性思维独具特征,在有效甄别信息、变革思维方式、推动学术创新、塑造创新型人才等方面有着重要的现实意义。     

基于关键链的项目工期风险断链式控制研究

以关键链为物质载体的风险效应的传递在外界环境的作用下，具有一定的扩增性。本文在关键链的基础上，从风险效应链式形态出发，通过对项目工期风险链式传递机理的分析，识别项目关键链上的关键工期风险结点，针对性的将关键链管理中的项目缓冲分解到关键结点之后，有效抑制其关键结点的传递途径，从而达到断链的效果，减少破坏的扩增性，达到风险控制的目的，从而提高项目管理的效率。
