维特根斯坦论“否定之谜”

“否定之谜”是早期分析哲学中广泛讨论的问题.维特根斯坦对此做出过很多论述.前期维特根斯坦主要通过命题意义的图像论对否定疑难进行处理.中后期维特根斯坦转向了日常语言分析,从语法自治性和多样性两个角度进行阐发.维特根斯坦认为,正确处理词与句的关系是解决“否定之谜”的关键.     

Logistic regression and other discrete data models for serially correlated observations

Summary We consider the analysis of discrete serially correlated data in the presence of time dependent covariates. If the interest is to relate the covariates to the marginal distribution of the data, Markov chains are an obvious tool to consider, but their use is complicated by the fact that they are expressed in terms of transitional rather than marginal probabilities. We show how to parametrize the transition matrix in a suitable way so that interpretation is as desired. The focus is on binary and Poisson data, but the methodology can be adopted also with other discrete data distributions.     

马克思恩格斯对“旧意识形态”的批判

在对“旧意识形态”的批判中，马克思、恩格斯创立了历史唯物主义．“旧意识形态”是对社会存在的反映，有其存在的合理性和虚假性，虚假性产生的社会历史根源在于生方式的狭隘性．因而，对“旧意识形态”的批判必然走向对狭隘生产方式的批判．马克思、恩格斯的批判方法仍有借鉴意义。     

非等量比较结构中的缩约

许多著名语法家，如夸克、利奇，对非等量比较结构的句法特征和语义特征，有不同的论述，争议颇多。本文试图论述缩约这一语法原则在非等量比较结构中运用后产生的不同缩约类型，并根据缩约的还原性特点分析其句法结构及非等量比较结构中的否定现象。     

Transition psychology: the membership approach

改革开放以来的中国社会转型给中国社会心理学者提供了独特的社会实验室。为 了描述、理解和解释社会转型中的中国人心理和行为逻辑，应该呼唤直面社会转型的 社会心理学研究，或转型心理学的研究，以超越文化特异性路径和稳态社会路径。其 可能的核心构念是多元群体（成员）资格。

关键词: 转型心理学 文化特异性路径 稳态社会路径 部分群体资格

China's social transformation since reform and opening up in 1978 has provided a unique social laboratory for Chinese researchers of social psychology. In order to describe, understand and interpret the psychological and behavioral logic of the Chinese people, we need to call on social psychology research or social transition psychology research that looks directly at social transition, in order to go beyond the cultural exceptionalism and static society approaches. Multiple group membership is the potential core construct of such a psychology.     

On the distributions of the differences between the estimated autocorrelations and partial autocorrelations at the same lag

Pukkila (1982) introduced a new portmanteau-type test of white noise. The test is based on the differences between the estimated autocorrelations and the corresponding partial autocorrelations. In the present paper the distributions of these differences are consider in the case of normal white noise. Approximations to these distributions are given. Goodness of fit of these theoretical distributions and the corresponding observed distributions is studied using simulated time series of various lengths.     

A non-inferiority test for diagnostic accuracy in the absence of the golden standard test based on the paired partial areas under receiver operating characteristic curves

Non-inferiority tests are often measured for the diagnostic accuracy in medical research. The area under the receiver operating characteristic (ROC) curve is a familiar diagnostic measure for the overall diagnostic accuracy. Nevertheless, since it may not differentiate the diverse shapes of the ROC curves with different diagnostic significance, the partial area under the ROC (PAUROC) curve, another summary measure emerges for such diagnostic processes that require the false-positive rate to be in the clinically interested range. Traditionally, to estimate the PAUROC, the golden standard (GS) test on the true disease status is required. Nevertheless, the GS test may sometimes be infeasible. Besides, in a lot of research fields such as the epidemiology field, the true disease status of the patients may not be known or available. Under the normality assumption on diagnostic test results, based on the expectation-maximization algorithm in combination with the bootstrap method, we propose the heuristic method to construct a non-inferiority test for the difference in the paired PAUROCs without the GS test. Through the simulation study, although the proposed method might provide a liberal test, as a whole, the empirical size of the proposed method sufficiently controls the size at the significance level, and the empirical power of the proposed method in the absence of the GS is as good as that of the non-inferiority in the presence of the GS. The proposed method is illustrated with the published data.     

Estimation and Inference of Distributional Partial Effects: Theory and Application

This article considers nonparametric and semiparametric estimation and inference of the effects of a covariate, either discrete or continuous, on the conditional distribution of a response outcome. It also proposes various uniform tests following estimation. This type of analysis is useful in situations where the econometrician or policy-maker is interested in knowing the effect of a variable or policy on the whole distribution of the response outcome conditional on covariates and is not willing to make parametric functional form assumptions. Monte Carlo experiments show that the proposed estimators and tests are well-behaved in small samples. The empirical section studies the effect of minimum wage hikes on household labor earnings. It is found that the minimum wage has a heterogenous impact on household earnings in the U.S. and that small hikes in the minimum wage are more effective in improving the household earnings distribution.
