• LISREL使用.pdf

    PRELIS 是LISREL的一部分。它主要用于在构建结构模型之前,对数据进行前期处理和初 步分析。PRELIS 的主要用途包括: o 将其它格式的数据文件(SAS, SPSS, Excel, Stat 等等)读入并存储为PRELIS 数据文 件。 o 将 PRELIS(*.psf)数据输出为其他软件可读的相应格式。 o 对 PRELIS 数据进行处理。(定义变量类型,处理缺失值,数据筛选,生成子数据集 等)。 o 回归模型分析及初步的因子分析等。 o 计算矩阵(协方差矩阵,多项相关系数以及渐近协方差矩阵等)。 o 可以用图表直观地表现数据的状况。 在这里,我们用不同类型的变量为例介绍如何应用PRELIS 来实现上述功能。本章中的 所有数据都存在LISREL 安装文件夹中的TUTORIAL 子文件夹里。

  • 社会网络的动态分析与仿真实验-理论与应用

    《社会网络的动态分析与仿真实验:理论与应用》主要讲述了,随着网络化和数字化的发展,社会网络在社会学、管理学和情报学等领域已经成为研究热点。由于社会网络是动态演化并存在于复杂社会技术系统中,但是传统的社会网络分析方法集中于对某一横截面数据的静态分析,在应对网络的复杂性和动态性的研究上很难胜任。《社会网络的动态分析与仿真实验:理论与应用》结合作者多年的研究成果,介绍了社会网络动态分析和仿真实验的理论与应用,并尝试将“网络实证分析”和“网络建模仿真”两方面研究结合起来,对社会网络的动态性进行研究。全书分理论与应用两部分。理论部分介绍了社会网络动态分析和社会网络仿真与计算实验理论相关的若干问题与实施方法。应用部分介绍了作者在联盟网络的演化、开源社会网络的协同、基于地理信息的引文网络评价、引文网络局部动态性分析上的实证研究成果,以及在网络信息传播、组织网络适应性、信息技术的采纳与扩散、基于元网络的交互系统影响、政府组织群体网络的信息化行为上的仿真研究成果。

  • 智能主体及其应用.pdf

    智能主体是一种处于一定环境下包装的计算机系统,为了实现设计目的,它能在那种环境下灵活地、自主地活动。智能主体提供了一种新的计算和问题求解风范。在人工智能研究中,主体概念的回归并不单单是因为人们认识到了应该把人工智能各个领域的研究成果集成为一个具有智能行为概念的“主体”,更重要的原因是人们认识到了人类智能的本质是一种社会性的智能。

  • The Proof Theory and Semantics of Intuitionistic Modal Logic

    Possible world semantics underlies many of the applications of modal logic in computer science and philosophy. The standard theory arises from interpreting the semantic de nitions in the ordinary meta-theory of informal classical mathematics. If, however, the same semantic de nitions are interpreted in an intuitionistic metatheory then the induced modal logics no longer satisfy certain intuitionistically invalid principles. This thesis investigates the intuitionistic modal logics that arise in this way. Natural deduction systems for various intuitionistic modal logics are presented. From one point of view, these systems are self-justifying in that a possible world interpretation of the modalities can be read o directly from the inference rules. A technical justi cation is given by the faithfulness of translations into intuitionistic rst-order logic. It is also established that, in many cases, the natural deduction systems induce well-known intuitionisticmodal logics, previously given by Hilbertstyle axiomatizations. The main bene t of the natural deduction systems over axiomatizations is their susceptibility to proof-theoretic techniques. Strong normalization (and con uence) results are proved for all of the systems. Normalization is then used to establish the completeness of cut-free sequent calculi for all of the systems, and decidability for some of the systems. Lastly, techniques developed throughout the thesis are used to establish that those intuitionistic modal logics proved decidable also satisfy the nite model property. For the logics considered, decidability and the nite model property presented open problems

  • An introduction to fibrations, topos theory, the effective topos and modest sets

    A topos is a categorical model of constructive set theory. In particular, the e ective topos is the categorical 'universe' of recursive mathematics. Among its objects are the modest sets, which form a set-theoretic model for polymorphism. More precisely, there is a bration of modest sets which satis es suitable categorical completeness properties, that make it a model for various polymorphic type theories. These lecture notes provide a reasonably thorough introduction to this body of material, aimed at theoretical computer scientists rather than topos theorists. Chapter 2 is an outline of the theory of brations, and sketches how they can be used to model various typed -calculi. Chapter 3 is an exposition of some basic topos theory, and explains why a topos can be regarded as a model of set theory. Chapter 4 discusses the classical PER model for polymorphism, and shows how it 'lives inside' a particular topos|the e ective topos|as the category of modest sets. An appendix contains a full presentation of the internal language of a topos, and a map of the e ective topos. Chapters 2 and 3 provide a sampler of categorical type theory and categorical logic, and should be of more general interest than Chapter 4. They can be read more or less independently of each other; a connection is made at the end of Chapter 3. The main prerequisite for reading these notes is some basic category theory: limits and colimits, functors and natural transformations, adjoints, cartesian closed categories. No knowledge of indexed categories or categorical logic is needed. Some familiarity with 'ordinary' logic and typed -calculus is assumed.
