清末民初东北进步报刊的境遇及其历史作用

清末民初,东北进步人士纷纷创办报刊,启迪民智,宣传民主革命思想。沙俄、日本殖民势力和东北当局为防止进步思想的传播,联合扼杀进步报刊,东北报业处于白色恐怖笼罩之中。在这段历史时期,东北报业所发挥的积极历史进步作用,及其自身所具有的局限性,值得我们认真总结。

农民工市民化的社会保障机制创建——基于我国东、中、西部及东北部分地区的农村调查

农民工是我国当今最重要的社会现象之一,是城市化进程的推进力量,也是城乡统筹发展的纽带。由于城乡二元经济社会结构及其制度安排,导致相关的农民工问题层出不穷,降低了农民工作为生产要素的生产效率。而农民工市民化无疑是解决这一问题的根本路径和最终选择,应通过城市社会保障和农村土地保障制度及机制的合理创建,尤其是通过保留进城农民在本轮承包期内的承包地,允许其长期流转,降低农民工市民化的机会成本。     

天津区县工业园区规划编制方法研究

一、引言 伴随着中国城市化进程的推进和经济发展,区县工业区的发展也进入了一个新的时代,在国民经济中占有的地位越来越重要.相比国家级、市级开发区,区县工业区功能相对单一,产业发展特色突出,在规划编制中对实施性和操作性的要求最为强烈,这就对传统的规划编制体系和规划编制方法提出了新的要求.在天津近期开展的区县示范工业园区的规划编制实践中,探索尝试了适应区县工业区快速发展建设需求的规划编制方法.     

Three Approximate Solutions to the Multivariate Behrens–Fisher Problem

ABSTRACT

This article provides three approximate solutions to the multivariate Behrens–Fisher problem: the F statistic, the Bartlett, as well as the modified Bartlett corrected statistics. Empirical results indicate that the F statistic outperforms the other two and five existing procedures. The modified Bartlett corrected statistic is also very competitive.     

Confidence Intervals for Survival Probabilities: A Comparison Study

The confidence interval of the Kaplan–Meier estimate of the survival probability at a fixed time point is often constructed by the Greenwood formula. This normal approximation-based method can be looked as a Wald type confidence interval for a binomial proportion, the survival probability, using the “effective” sample size defined by Cutler and Ederer. Wald-type binomial confidence interval has been shown to perform poorly comparing to other methods. We choose three methods of binomial confidence intervals for the construction of confidence interval for survival probability: Wilson's method, Agresti–Coull's method, and higher-order asymptotic likelihood method. The methods of “effective” sample size proposed by Peto et al. and Dorey and Korn are also considered. The Greenwood formula is far from satisfactory, while confidence intervals based on the three methods of binomial proportion using Cutler and Ederer's “effective” sample size have much better performance.     

Incremental modelling for compositional data streams

ABSTRACT

Incremental modelling of data streams is of great practical importance, as shown by its applications in advertising and financial data analysis. We propose two incremental covariance matrix decomposition methods for a compositional data type. The first method, exact incremental covariance decomposition of compositional data (C-EICD), gives an exact decomposition result. The second method, covariance-free incremental covariance decomposition of compositional data (C-CICD), is an approximate algorithm that can efficiently compute high-dimensional cases. Based on these two methods, many frequently used compositional statistical models can be incrementally calculated. We take multiple linear regression and principle component analysis as examples to illustrate the utility of the proposed methods via extensive simulation studies.
