概念迁移视阈下基于语料库的非英语专业学习者动名词搭配错误研究

文章拟从概念迁移视角研究大学英语写作中的动-名词搭配错误，研究采用语料库定量与定性相结合的分析方法。语料取材于中国学习者英语语料库（CLEC），包括大学英语低年级学习者（St3）和高年级学习者（St4）两个子语料库。利用检索工具Ant Conc3.58检索中国学习者作文中的动-名词搭配错误，从而对大学生英语写作中的动-名词搭配错误进行描述与分类，进而分析造成大学生英语写作动-名词搭配误用的潜在原因，并对现有大学英语教学做出反思。     

A volume based approach to establish B-spline based expressions for density functions and its application to progressive hybrid censoring

We propose an approach to determine the distribution of particular linear combinations of hybrid censored order statistics which is based on the calculation of volumes of polytopes. For this purpose, we establish efficient and compact volume formulas in terms of B-splines. Further, we illustrate our approach for ten different progressive hybrid censoring schemes under an exponential assumption.     

Conditional time-dependent nonparametric estimators with an application to healthcare production function

ABSTRACT

By using the probabilistic framework of production efficiency, the paper develops time-dependent conditional efficiency estimators performing a non-parametric frontier analysis. Specifically, by applying both full and quantile (robust) time-dependent conditional estimators, it models the dynamic effect of health expenditure on countries’ technological change and technological catch-up levels. The results from the application reveal that the effect of per capita health expenditure on countries’ technological change and technological catch-up is nonlinear and is subject to countries’ specific income levels.     

论公共管理实践中的“试点”方法

试点是我国公共管理实践中常用的一种方法,是政策制定的一个有机组成部分,为各级公共管理部门所广泛采用。当前我国公共管理部门所开展的试点越来越多,一方面说明试点是一种有效的公共管理方法,有利于提高制度设计的精度和可控性;另一方面也反映当前改革难度日趋加大,改革的不确定性逐渐增强。在实践中,试点方法又面临诸多挑战,影响了试点的内在效度和外在效度。因此,需要加强相关制度建设,以提高试点方法的内在效度与外在效度。     

从文化差异看旅游文字的汉译英

首先说明语言与文化之间密不可分的关系,进而根据中国和英语国家由于不同的哲学观而导致的截然不同的审美观及其在两种语言表达上的差异以及不同民族在社会和历史背景方面的差异,相应提出了旅游文字汉译英中可以采用的删减法和增添的两种翻译方法。     

梁启超的理性精神与学术态度

从“不为古人所欺，不为世法所挠”、“我物我格，我理我穷”，以及“除心奴”，反“依傍”三个层次论述了梁启超与西方启蒙主义相通的理性精神与学术态度。从理性精神的角度对众所周知的梁启超一生“多变”作了新的阐释。并认为，梁启超与王国维一样，具有“独立之精神，自由之思想”，只不过表现方式有所不同罢了。

A Bayesian Adjustment for Covariate Misclassification with Correlated Binary Outcome Data

Estimated associations between an outcome variable and misclassified covariates tend to be biased when the methods of estimation that ignore the classification error are applied. Available methods to account for misclassification often require the use of a validation sample (i.e. a gold standard). In practice, however, such a gold standard may be unavailable or impractical. We propose a Bayesian approach to adjust for misclassification in a binary covariate in the random effect logistic model when a gold standard is not available. This Markov Chain Monte Carlo (MCMC) approach uses two imperfect measures of a dichotomous exposure under the assumptions of conditional independence and non-differential misclassification. A simulated numerical example and a real clinical example are given to illustrate the proposed approach. Our results suggest that the estimated log odds of inpatient care and the corresponding standard deviation are much larger in our proposed method compared with the models ignoring misclassification. Ignoring misclassification produces downwardly biased estimates and underestimate uncertainty.
