阿特伍德《猫眼》中女性之间破坏性的权力关系

以米歇·尔福柯和厄玛·塞拉诺·加西亚的权利理论为视角,通过分析小说中女性之间权力关系的形成、维持、改变及其产生根源,主要论证二元对立的思维模式导致主人公从在多伦多定居到离开多伦多这段时间里与其他女孩和成年女性所形成的关系都是施害者和受害者模式,指出阿特伍德通过揭露女性对女性的伤害批判了将女性所有问题归于男权社会这一简单化倾向,突破了女权主义运动中将女性关系描绘为姐妹情谊这样的局限性,打破人们贴标签式的看问题方法。     

Two-sample tests for sparse high-dimensional binary data

In this article, we study the methods for two-sample hypothesis testing of high-dimensional data coming from a multivariate binary distribution. We test the random projection method and apply an Edgeworth expansion for improvement. Additionally, we propose new statistics which are especially useful for sparse data. We compare the performance of these tests in various scenarios through simulations run in a parallel computing environment. Additionally, we apply these tests to the 20 Newsgroup data showing that our proposed tests have considerably higher power than the others for differentiating groups of news articles with different topics.     

Joint modeling of correlated binary outcomes: HIV-1 and HSV-2 co-infection

Herpes Simplex Virus Type 2 (HSV-2) facilitates the sexual acquisition and transmission of HIV-1 infection and is highly prevalent in most regions experiencing severe HIV epidemics. In sub-Saharan Africa, where HIV infection is a public health burden, the prevalence of HSV-2 is substantially high. The high prevalence of HSV-2 and the association between HSV-2 infection and HIV-1 acquisition could play a significant role in the spread of HIV-1 in the region. The objective of our study was to identify risk factors for HSV-2 and HIV-1 infections among men in sub-Saharan Africa. We used a joint response model that accommodates the interdependence between the two infections in assessing their risk factors. Simulation studies show superiority of the joint response model compared to the traditional models which ignore the dependence between the two infections. We found higher odds of having HSV-2/HIV-1 among older men, in men who had multiple sexual partners, abused alcohol, or reported symptoms of sexually transmitted infections. These findings suggest that interventions that identify and control the risk factors of the two infections should be part of HIV-1 prevention programs in sub-Saharan Africa where antiretroviral therapy is not readily available.     

中国对东盟出口贸易额的二元边际研究

为了研究中国出口东盟贸易,采用UN Comtrade数据库HS六位编码数据,根据HK分解法计算出口贸易的二元边际,并运用扩展后的引力模型分析其影响因素。为确保结果稳健性,使用PPML进行检验。研究结论显示:中国出口东盟主要沿着集约边际增长,扩展边际对制造业出口贡献更大。中国经济规模、中新自由贸易区协定的签署对二元边际起促进作用,但是东盟经济规模和贸易自由度会阻碍二元边际的增长。     

“文质模式”与中国古代经典阐释学

"文质模式"是儒家理解社会政治、历史和文学艺术的独特视角,是一种极为重要的阐释模式,集中体现了儒家的政治理念与人格理想。在孔子那里,"文质模式"原本是关于君子人格的规范性标准,其内涵是传统贵族精神与新兴士人趣味的复合体。在汉儒那里,这一模式就演变成了考察社会历史的阐释框架,衍化为一种政治标准。而到了汉魏之际,这一模式再进而演变为衡量诗文书画风格特征的尺度,成为一种审美趣味。值得注意的是,这一阐释模式意义与功能的演变始终与古代士人阶层身份意识紧密相关。     

对双宾语结构合法性的思考

为了避免或减少由双宾语结构引起的理论冗余和导致的教学尴尬,本文重审双宾语结构研究中的两大焦点问题——格问题与主目结构问题,发现:双宾语结构中的直宾与间宾不能都获得宾格,从而无法成为合法的动词宾语。因此,双宾语结构不具有句法学意义上的合法性,而只存于语言表象。这一推论得到了语言事实的印证。

Graphics for studying logistic regression models

In this article we focus on logistic regression models for binary responses. An existing result shows that the log-odds can be modelled depending on the log of the ratio between the conditional densities of the predictors given the response variable. This suggests that relevant statistical information could be extracted investigating the inverse problem. Thus, we present different methods for studying the log-density ratio through graphs, which allow us to select which predictors are needed, and how they should be included in a logistic regression model. We also discuss data analysis examples based on real datasets available in literature in order to provide further insights into the methodology proposed.     

Efficiency of generalized estimating equations for binary responses

Summary.  Using standard correlation bounds, we show that in generalized estimation equations (GEEs) the so-called 'working correlation matrix' R ( α ) for analysing binary data cannot in general be the true correlation matrix of the data. Methods for estimating the correlation param-eter in current GEE software for binary responses disregard these bounds. To show that the GEE applied on binary data has high efficiency, we use a multivariate binary model so that the covariance matrix from estimating equation theory can be compared with the inverse Fisher information matrix. But R ( α ) should be viewed as the weight matrix, and it should not be confused with the correlation matrix of the binary responses. We also do a comparison with more general weighted estimating equations by using a matrix Cauchy–Schwarz inequality. Our analysis leads to simple rules for the choice of α in an exchangeable or autoregressive AR(1) weight matrix R ( α ), based on the strength of dependence between the binary variables. An example is given to illustrate the assessment of dependence and choice of α .
