Comparing Latent Means Without Mean Structure Models: A Projection-Based Approach

The conventional setup for multi-group structural equation modeling requires a stringent condition of cross-group equality of intercepts before mean comparison with latent variables can be conducted. This article proposes a new setup that allows mean comparison without the need to estimate any mean structural model. By projecting the observed sample means onto the space of the common scores and the space orthogonal to that of the common scores, the new setup allows identifying and estimating the means of the common and specific factors, although, without replicate measures, variances of specific factors cannot be distinguished from those of measurement errors. Under the new setup, testing cross-group mean differences of the common scores is done independently from that of the specific factors. Such independent testing eliminates the requirement for cross-group equality of intercepts by the conventional setup in order to test cross-group equality of means of latent variables using chi-square-difference statistics. The most appealing piece of the new setup is a validity index for mean differences, defined as the percentage of the sum of the squared observed mean differences that is due to that of the mean differences of the common scores. By analyzing real data with two groups, the new setup is shown to offer more information than what is obtained under the conventional setup.     

从自由与平等的关系看获取正义

获取之正义乃是人类的千古困惑.获取正义之原则必须而且只能从社会主义社会理念中导出,该理念是:人人生而自由,人人生而平等,没有贵族,没有特权,没有压迫,没有剥削,公共职位向所有公民开放,人人有权选择并努力实现自己所向往的幸福生活.在此理念之下,自由与平等之关系是:公民之间的平等是基于自由权利的平等.社会主义社会理念下的获取正义包括:每个公民都有从自然资源中获取收益的社会权利;合法的市场交易所得;其他合法途径,如遗产继承、馈赠等.任何一个认同社会主义社会理念的人均不赞成公共财政充当劫富济贫的\"佐罗\"角色,但保障每个公民都能够从自然资源的收益中获得生存资料乃是政府之责任、公民之权利,税收资源的主要功能是创造和维护社会秩序、保障本民族的集体安全、满足公共事务的需要.     

尼古丁依赖的神经生物学机制

尼古丁依赖是香烟成瘾的主要原因,其特征为无法克制的尼古丁觅求冲动,以及强迫性地、连续地使用尼古丁,以体验其带来的欣快感和愉悦感,并避免可能产生的戒断症状。该文主要从动物模型和人类脑功能成像两个方面来综述已有关于尼古丁依赖的神经生物学机制的研究成果,发现中脑边缘多巴胺系统是尼古丁依赖中的重要神经生物学基础。然而,目前对于尼古丁依赖的研究主要从静态的角度出发,较少研究其动态过程;并且尼古丁依赖与其他药物依赖之间的差异也缺乏直接的证据,因此这些都将成为将来可能的研究方向。     

论儒家必为大一统的思想基础

儒家全面秉承了周文,在思想与规则上对社会生活都有全面的设计与安排,有助于安顿百姓的日常生活。儒家最终因汉武帝的罢黜百家,表章六经而被独尊,承担着秦汉以来的大一统的思想共源的基础作用,并据之建构起中华民族的公共交往平台,成为中华民族的精神家园。     

青少年期母子性格与家庭亲密度的关系:性格喜好的作用

研究旨在考察性格喜好与母子性格、家庭成员亲密度的关系以及性格喜好在其他两个变量之间的中介作用。成都市632对初高中学生及其母亲分别自评并填写了艾森克人格问卷,同时评价喜欢对方性格的程度。另外,青少年还报告了与家庭成员的亲密程度。通过相关分析、多元方差分析、层级回归分析以及结构方程模型建模,结果发现：性格喜好与母亲性格、青少年性格均有显著关系,青少年对母亲的性格喜好程度与家庭成员间的亲密感有显著正相关。青少年性格和青少年对母亲的性格喜好程度能直接预测家庭成员亲密度,同时青少年和母亲的性格还通过青少年对母亲的性格喜好程度间接作用于家庭亲密度,提示性格喜好在二者的关系中发挥了重要的中介作用。     

影响儿童情绪自我调节的因素

情绪自我调节较多的研究主要集中在有关情绪自我调节的表现方式和发展阶段水平方面,本文则从情绪自我调节的积极指向方面探讨其影响因素,认为大脑成熟顺序、社会认知发展及文化宗教等方面的因素影响着儿童的情绪自我调节.为对儿童的发展进行更好的干预提供依据.     

论"自我"的自欺本质

自我意识就是把自己当对象看、同时又把对象当自我看的意识,但对象和自我本来是不同的,因此自我意识里面包含一个自欺结构。这种结构从形式逻辑和日常意识来看是自相矛盾的,必然导致无穷后退并引出一个上帝;但从辩证法来理解则正是主体的能动性之源。这种有意识的自欺使人生成为艺术,但也体现了人性的“根本恶”,能够调解这种自相矛盾的只有忏悔。忏悔不是一次性的,而是不断深入的无限过程,只有在这一反思和怀疑的过程中,人性才能越来越真诚。     

宗教裁判所与检察制度的萌芽

宗教裁判所因对异端的迫害而臭名昭著.然而,正是从其秘密、刑讯逼供、有罪推定等今天看来缺乏最基本的程序正义的审判方式中,蕴育出现代检察制度的胚芽.宗教裁判所公共起诉和由机构控诉等做法,对于现代检察制度的萌芽产生了积极的促进作用,而纠问式审判的弊端,也从反面催生了现代检察制度.     

"本质"的双重含义:自然科学与人文科学——黑格尔、狄尔泰、胡塞尔之间的一点链接

Early in Aristotle’s terminology, and ever since, “essence” has been conceived as having two meanings, namely “universality” and “individuality”. According to the tradition of thought that has dominated throughout the history of Western philosophy, “essence” unequivocally refers to “universality”. As a matter of fact, however, “universality” cannot cover Aristotle’s definition and formulation of “essence”: Essence is what makes a thing “happen to be this thing.” “Individuality” should be the deep meaning of “essence”. By means of an analysis of some relevant Western thoughts and a review of cultural realities, it can be concluded that the difference between the attitudes toward things of the natural sciences and the humane sciences mainly lies in the fact that the former focus on the pursuit of universal regularity, whereas the latter go after the value and significance of human life. The movement from natural things to cultural things is a process in which essence shifts from universality to individuality. It is the author’s contention that what should be stressed in the fields of human culture and society is the construction of an ideal society that is “harmonious yet not identical”, on the basis of respecting and developing individual peculiarity and otherness.

展开模型和优势模型在职业兴趣测验中的比较研究

该研究调查了展开模型(GGUM)和优势模型(GRM)对职业兴趣测验反应数据的拟合情况,并对展开模型和优势模型两种测验编制方法在职业兴趣测验中进行了比较。结果发现:(1)展开模型的模型拟合情况和测量精度优于累积模型,两种模型对被试能力参数估计的差异主要体现在极端被试上,对兴趣水平极端高的被试,展开模型的估计值更精确;(2)采用展开模型编制的测验在信度上远远高于Likert方法编制的测验,中间区域题目的增加提高了测验的信度,但两种方法在测验的效标关联效度上没有差异。结果表明,在职业兴趣的测量上,展开模型更精确;在职业兴趣测验的编制上,GGUM和Likert法没有差异,反而Likert法具有简便、易懂的优势。
