中国农民工政策过程的批评话语分析——基于“农民工”称谓演变的视角

对"农民工"称谓演变的微观话语分析发现,农民工政策话语在建构社会的同时,也受制于社会结构.我国政府处理农民工事务的行动逻辑正逐步从"服务于经济发展"转向"关注社会民生".政策变迁映射和推动了社会变迁,我国农村向城市的人口流动在经历"严苛管制"自由流动"历程后,正朝着渐进式市民化方向发展.研究还发现,批评话语分析视角下的微观话语解构是政策分析的有效切入点,有助于唤起更深刻理性的政策协商,促进社会公平.     

从多模态话语分析视角看广告语言的映像象似性

语言的象似性指语言的表达形式与其表达的内容之间有某种象似关系。在广告英语中,映像象似性广泛存在于语言的音系、排版、字体等多模态手段中,是人们有意识使用的一种手段。搜集大量21世纪以来的品牌广告语料,试图通过多模态话语分析理论对英语广告中映像象似原则及其功能进行较为全面的分析,从而说明映像象似性理论在广告语言中的恰当运用,并证明认知语言学的相似性与功能语言学的多模态话语分析相结合的新领域研究方向。     

On the Critical Value Behaviour of Multiple Decision Procedures

In this paper we investigate the asymptotic critical value behaviour of certain multiple decision procedures as e.g. simultaneous confidence intervals and simultaneous as well as stepwise multiple test procedures. Supposing that n hypotheses or parameters of interest are under consideration we investigate the critical value behaviour when n increases. More specifically, we answer e.g. the question by which amount the lengths of confidence intervals increase when an additional parameter is added to the statistical analysis. Furthermore, critical values of different multiple decision procedures as for instance step-down and step-up procedures will be compared. Some general theoretic results are derived and applied for various distributions.     

环形筋压筋不起外皱的临界计算及试验研究

拉深筋可以用来防止内皱的出现。本文对拉深件成形前环形筋在压靠过程中，筋的外围材料不发生外皱的机理进行了理论分析和试验研究，得到了压筋时不起外皱的临界表达式。为了得到环形筋的合理位置，本文还推出了材料在压筋时不被拖入艋中的验证公式。     

紧缩时代的新极端主义和干扰政治

美国主流媒体有关财政悬崖危机等孤立议题的辩论,是一种转移公众注意力的干扰性话语政治学,它旨在强化去政治化和威权主义的新模式,割裂人们对个体困境与公共利益考虑之间的联系。在民主共和两党尤其是共和党极端主义对福利国家、公共利益和责任政府的大肆攻击之下,美国已经变成精神上的威权国家,市场极端主义和极端个人主义甚嚣尘上,想象力、能动性和希望被窒息。在此情况下,批判教育学成为正义、社会责任和民主意义的核心,帮助人们争取集体夺回民主斗争的胜利。     

When Form Fails to Follow Function

Abstract

Benjamin and Gollan'S (2003) new primer on conducting child custody evaluations, published by the American Psychological Association, presents the authors' flawed evaluation protocol with little discussion of the risks and benefits of the practices they advocate. The authors fail to note where their model varies significantly from the custody evaluation guidelines required by law in some states, and promulgated by various professional organizations. The most troubling practices include not interviewing and assessing pre-adolescent children, destroying videotapes of interviews and observation sessions, organizing the evaluation around parental allegations, use of a suggestive allegation checklist, and limiting consideration of information from collateral witnesses to declarations submitted under penalty of perjury.     

变截面压杆的临界荷载计算

变截面杆件的临界载荷问题，其平衡方程为变系数微分方程，只有少部分的情况可以得到其解析解，采用改进的WBK法,计算了若干变截面压杆的临界荷载，并与有限差分法进行了对比，证实了其可靠性。     

具反射边界条件的板模型迁移系统的临界性

研究非均匀介质,各向同性,具反射边界条件的板模型迁移系统的临界解.借助泛函分析方法,特别是Lp空间上的线性算子理论,证明了积分算子的主本征值(即临界参数)的性质,并获得了系统处于次临界状态的条件以及使系统处于临界状态的板厚度的存在性.     

Critical Effects and Exposure Limits

The use of critical effects in the determination of occupational exposure limits (OELs) in Sweden is subjected to a statistical study. Many of the present OELs are high in relation to known noeffect levels and effect levels, and the degree of protection has a surprisingly weak correlation with the seriousness of the adverse effect. Several proposals for improved procedures are put forward. One of these is to supplement the concept of critical effects with that of dominant effects. A dominant effect of a substance is a health effect that is at some concentration the most serious health effect.     

论非形式逻辑及其基本特征

非形式逻辑是在传统逻辑和数理逻辑之后产生出来的一门新兴学科,它的根本作用是培养和训练人的逻辑思维和理性思维能力,既能体现思维形式和思维内容的完美结合,也能体现思维的确定性和不确定的完美结合,是案例教学学科整体发展趋势的反应。
