早期马克思主义学者队伍分化的渊源探讨

早期马克思主义学者队伍分化有其客观必然性。转型期中国社会现实的复杂与多变,是导致队伍分化的社会根源;马克思主义在中国早期传播呈现出发展性和复杂性,是导致队伍分化的思想根源;早期马克思主义学者的队伍鱼龙混杂,是导致队伍分化的组织根源。早期马克思主义学者队伍分化又带有主体选择的偶然性。阶级立场、政治理念是影响主体选择的内在因素;党派聚散离合、人际网络等个人机缘是影响主体选择的外在因素。     

流动人口的社会保险覆盖率及其影响因素分析

利用国家卫计委2010年12月的全国性大规模调查数据,本文研究了城市外来流动人口的社会保险覆盖率及其影响因素。研究发现,教育和培训提高了流动人口的参保概率;企业所有制性质、有无劳动合同,显著影响流动人口的参保;农民工各项社会保险的参保状况显著低于城城流动人口,并且中部地区流动人口的社会保险参保率显著低于东部和西部地区。流动人口不再是被动的社会保险获得者,已经有了一定的主动权。在提高流动人口社会保险覆盖率的政策设计上,除了加强流动人口的职业培训和教育之外,还应该严格落实新《劳动合同法》的实施,将农民工作为社会保险扩面工程的重点人群,并将中部地区作为扩面工程的重点区域。     

On Complete Convergence for an Extended Negatively Dependent Sequence

In this article, the Rosenthal-type maximal inequality for extended negatively dependent (END) sequence is provided. By using the Rosenthal type inequality, we present some results of complete convergence for weighted sums of END random variables under mild conditions.     

Local Influence Analysis for The Ridge Regression Under Stochastic Linear Restrictions

In this article, we assess the local influence for the ridge regression of linear models with stochastic linear restrictions in the spirit of Cook by using the log-likelihood of the stochastic restricted ridge regression estimator. The diagnostics under the perturbations of constant variance, responses and individual explanatory variables are derived. We also assess the local influence of the stochastic restricted ridge regression estimator under the approach suggested by Billor and Loynes. At the end, a numerical example on the Longley data is given to illustrate the theoretic results.     

On Bahadur representation for sample quantiles under α-mixing sequence

In this paper, by relaxing the mixing coefficients to α(n) = O(n ^?β), β > 3, we investigate the Bahadur representation of sample quantiles under α-mixing sequence and obtain the rate as ${O(n^{-\frac{1}{2}}(\log\log n\cdot\log n)^{\frac{1}{2}})}$ . Meanwhile, for any δ > 0, by strengthening the mixing coefficients to α(n) = O(n ^?β ), ${\beta > \max\{3+\frac{5}{1+\delta},1+\frac{2}{\delta}\}}$ , we have the rate as ${O(n^{-\frac{3}{4}+\frac{\delta}{4(2+\delta)}}(\log\log n\cdot \log n)^{\frac{1}{2}})}$ . Specifically, if ${\delta=\frac{\sqrt{41}-5}{4}}$ and ${\beta > \frac{\sqrt{41}+7}{2}}$ , then the rate is presented as ${O(n^{-\frac{\sqrt{41}+5}{16}}(\log\log n\cdot \log n)^{\frac{1}{2}})}$ .     

试析表示“科举及第”意义的典故词

科举考试兴盛于唐宋时期,开通了平民入仕的道路。读书人期待一举成名天下知,创造了一些雅致的表示科举及第的词汇。这些词汇有的出自《尚书》,有的来源于《庄子》和其他古代诗文。本文以时代为线索,对这些典故词进行了初步分析。了解这些词汇的来源,有助于我们更好地理解古代文献,进一步探求科举文化的内涵。       

Modeling potential time to event data with competing risks

Patients receiving radical prostatectomy are at risk of metastasis or prostate cancer related death, and often need repeated clinical evaluations to determine whether additional adjuvant or salvage therapies are needed. Since the prostate cancer is a slowly progressing disease, and these additional therapies come with significant side effects, it is important for clinical decision making purposes to estimate a patient’s risk of cancer metastasis, in the presence of a competing risk by death, under the hypothetical condition that the patient does not receive any additional therapy. In observational studies, patients may receive additional therapy by choice; the time to metastasis without any therapy is often a potential outcome and not always observed. We study the competing risks model of Fine and Gray (J Am Stat Assoc, 94:496–509, 1999) with adjustment for treatment choice by inverse probability censoring weighting (IPCW). The model can be fit using standard software for partial likelihood with double IPCW weights. The proposed methodology is used in a prostate cancer study to predict the post-prostatectomy cumulative incidence probability of cancer metastasis without additional adjuvant or salvage therapies.     

论东亚三国西学成果差异及其原因

东亚三国在文化层面上存在着东亚各国的文化差异,即东西文化交流与融合过程中,显现的东亚各国文化的传统特性。通过分析得出,东亚三国的历史文化传统差异是导致三国在不同时期、不同阶段形成西学成果及水准差异的主要原因。
