真作假时假充真——评叶植先生指白梅习氏“造假”的伪学术实质和反逻辑手法

习凿齿晚年徙居白梅,是"史不及载"的历史真实。叶植先生一再撰文否定,诬指白梅习氏"造伪",却举不出确凿证据,只得借无中生有、引用不实之录和讹误史料、曲解《白梅习氏族谱》及其序文、玩弄种种反逻辑手法以支撑虚假命题。中华民族尊重自己的历史和文化,国有史、方有志、家有谱。家谱是"祖国文化宝藏"。文史研究者理应善待家谱,善待历史,诚实研究,切勿自以为是挑战历史,玩弄历史。     

高层组合框架-混凝土筒体结构推覆分析

针对高层混合结构中适用于推覆分析的剪力墙单元与型钢混凝土构件塑性铰等问题进行研究,利用三垂直杆元模拟剪力墙,各杆元分别考虑剪力墙轴向、剪切与弯曲变形;根据型钢混凝土构件截面承载力与变形能力,给出了反映截面弯矩与转角关系的型钢混凝土构件塑性铰特性值计算方法;应用MIDAS/GEN软件作为弹塑性分析工具,采用改进的剪力墙单元模型,自定义型钢混凝土构件塑性铰特性值,对30层高混合结构进行推覆分析,并与模型试验结果对比,结果表明：推覆分析所得基底剪力-顶点位移曲线与试验结果较符合,各构件塑性铰分布及状态与模型试验的裂缝分布及破坏模式符合较好,能够反映出混合结构各构件变形和结构整体承载力变化过程.     

AN EXTENSION OF TOPSIS FOR FUZZY MCDM BASED ON VAGUE SET THEORY

1.Introduction The multicriteria decision-making problem(Kickert1978)is a kind of problem that all the alternatives in the choice set can be evaluated according to a number of criteria.A MCDM problem can be concisely expressed in matrix format as C1C2C n11112122122212nnm m m mnA x x xMA x x xA x x x=W={w1,w2,,wn}where A1,A2,,Am are possible alternatives among which decision-makers have to choose,C1,C2,,C n are the criteria with which alternative performance are measured,xi j is the rati…     

VIEWING URBAN DISRUPTIONS FROM A DECISION INFORMATICS PERSPECTIVE

1. Introduction Urban infrastructures are the focus of terrorist acts because, quite simply, they produce the most visible impact, if not casualties. From the September 11, 2001 (i.e., “9/11”) attack on New York City’s World Trade Center to the more recent March 11, 2004, attack on Madrid’s commuter trains, it is obvious that urban centers are indeed vulnerable to such hideous acts. A systemic or holistic approach to securing the infrastructure systems that underpin an urban center isr…     

MODELING COMMERCIAL PROCESSES AND CUSTOMER BEHAVIORS TO ESTIMATE THE DIFFUSION RATE OF NEW PRODUCTS

1. Introduction In his famous seminal book (Rogers 1962), Rogers introduced and popularized a generic framework for analyzing and describing how the mechanism of diffusion of innovations works inside a given population. In this general approach, “innovation” can of course be understood in a large way: it may indeed referto various contexts such as the learning of a new practice, the use of a new tool, the launch of a new product, etc. The strength of Rogers' point of view comes from the fac…     

AGENT-BASED SIMULATION FOR KANSEI ENGINEERING： TESTING A FUZZY LINEAR QUANTIFICATION METHOD IN AN ARTIFICIAL WORLD

This paper argues that agent-based simulation can be used as a way for testing Kansei Engineering methods which deal with the human reaction from sensory to mental state, that is, sensitivity, sense, sensibility, feeling, esthetics, emotion affection and intuition. A new fuzzy linear quantification method is tested in an artificial world by agent-based modeling and simulations, and the performance of the fuzzy linear method is compared with that of a genetic algorithm. The simulations can expand people＇s imagination and enhance people＇s intuition that the new fuzzy linear quantification method is effective.     

ORGANIZATIONAL LEARNING AND VENDOR SUPPORT QUALITY BY THE USAGE OF APPLICATION SOFTWARE PACKAGES： A STUDY OF ASIAN ENTREPRENEURS

In this paper we study how organizational learning impacts organizational behavior, and howvendor support quality enhances product adoption and usage behavior.These constructs were verifiedusing Application Software Packages(ASP)-a prewritten, precoded, commercially available set ofprograms that eliminates the need for individuals or organizations to write their own softwareprograms for certain functions. The relationship between ASP usage, usage outcomes and useprocesses were also investigated. Two hundred and ninety-five Chinese, Indian, and Malayentrepreneurships were studied. It was found that usage outcome strongly determines usage, while useprocess has only an indirect relationship (via outcome) on usage. The impact of organizational learningand vendor service quality on usage, usage outcome, and use process were robust. Theoretical andpractical implications of the research are discussed.
