Analysis of Contingency Tables with Clustered Observations

A new approach is presented for testing independence in contingency tables with clustered observations. The approach is based on the framework of generalized linear mixed models. Under the multinomial logistic link function, the category counts are modelled with random cluster effects and a modified likelihood ratio statistic is used for testing independence. The method is applicable to multi-way tables, and can accommodate multiple levels of clustering. It is illustrated using a benchmark dataset.     

浙江房地产业的产业功能定位研究

内容提要：本文利用浙江省投入产出表和相关的房地产业统计数据,在定性分析基础上,定量研究了浙江省房地产业的产业功能,否定了房地产业是浙江基础产业、先导产业、主导产业和产出、就业支柱产业的观点,证实了房地产业是浙江财政收入支柱的论断。     

高校青年教师职业倦怠的现状与缓解

教师职业倦怠是指教师在长时间的职业压力下心理失衡,导致其在生理、心理、情绪情感、行为等方面表现
出来的身心疲惫。近年来,随着我国高等学校青年教师队伍急剧增大,青年教师已经成为高校事业发展的一支重要力
量, 而在实际工作中青年教师面临来自教学、科研、住房、人际关系交往等多方面的压力,高校青年教师的职业怠倦成
为普遍现象。本文以Maslach 的倦怠三维度理论为基础,随机选取四川省5 所高校的青年教师为调查对象,采用问卷
调查方法,用职业倦怠调查普适量表作为测量工具,对现阶段我国高校青年教师的职业倦怠的现状进行调研,使用
SPSS17.0 统计软件处理数据,并从职业倦怠的情绪衰竭、个人成就感、去个性化三个维度进行探讨。最后结合具体情
况,针对高校青年教师职业怠倦的影响因素,从主观和客观两个层面提出了缓解职业倦怠的措施。     

中国投入产出表直接消耗系数变动研究

本文以中国1987、1992、1997、2002、2005年五张全国投入产出表为分析对象,研究了1987-2005年间中国投入产出表直接消耗系数的变动情况,研究表明：投入产出表直接消耗系数矩阵总体差异程度总体上为下降趋势;直接消耗系数的稳定性和直接消耗系数数值的大小有显著的正相关关系;直接消耗系数差异程度增大的部门主要集中于高科技产业部门,直接消耗系数差异程度减小的部门主要集中于传统产业;1987-2005年,中间总投入比成逐年增加,各个部门的中间投入比的平均值逐年下降,离散程度减小;1987-2005年,三次产业均增加了对第二产业的中间消耗、减小了对第一产业的中间消耗。     

从集部目录的流变看古代文学观念的演变——以《汉志》《隋志》《总目》为例

从集部角度比较《汉书.艺文志》《隋书.经籍志》《四库全书总目》,三部目录从诗赋略到集部的嬗变,既是文学观念逐步明晰的过程,也是目录学对文学客观认识的演进过程。从屈原赋之属到楚辞类,楚辞逐步走向经典。别集类的立类及书目传承一方面展示出作家主体地位逐步凸显,另一方面也反映文学正统观念的加强。     

里耶秦简九九表初探

里耶秦简九九表的文字、内容、句数均有其独特之处,它可以修正王国维《流沙坠简》考释中的某些结论：其一,先秦“小九九”并非只有36句一种。其二,九九表中“而”“如”通用。王国维“改‘而’作‘如’,始于宋代”之说不确。其三,敦煌汉简九九表末尾总合实为1113,而非1110。就数学史意义而言,秦简九九表体现了三个重要的数理内涵：乘法定义、乘法交换律、筹算基础。就文化史意义而言,秦简九九表与《周易》存在一定的比附关系。     

Bayesian model comparison based on expected posterior priors for discrete decomposable graphical models

The implementation of the Bayesian paradigm to model comparison can be problematic. In particular, prior distributions on the parameter space of each candidate model require special care. While it is well known that improper priors cannot be routinely used for Bayesian model comparison, we claim that also the use of proper conventional priors under each model should be regarded as suspicious, especially when comparing models having different dimensions. The basic idea is that priors should not be assigned separately under each model; rather they should be related across models, in order to acquire some degree of compatibility, and thus allow fairer and more robust comparisons. In this connection, the intrinsic prior as well as the expected posterior prior (EPP) methodology represent a useful tool. In this paper we develop a procedure based on EPP to perform Bayesian model comparison for discrete undirected decomposable graphical models, although our method could be adapted to deal also with directed acyclic graph models. We present two possible approaches. One based on imaginary data, and one which makes use of a limited number of actual data. The methodology is illustrated through the analysis of a 2×3×4 contingency table.     

Regression modelling of the flows in an input–output table with accounting constraints

This paper details a method for estimating the unknown parameters of a regression model when the estimates of the dependent variable should be embedded in an input–output table with accounting constraints. Since in regression modelling the dependent variable is usually transformed either to achieve homoscedasticity of the residuals or for a better interpretation of the model, the estimating procedure becomes an optimization problem of an opportunely defined Lagrangian function with non-linear constraints. After detailing the algorithm and deriving the asymptotic distribution of the restricted estimator, the methodology is applied to estimate the flows of tourism within and between Italian regions with a gravity model. The procedure can be seen as an extension of Byron’s (J R Stat Soc Ser A 141:359–367, 1978) balancing method.
