农民责任观现状的实证研究——以湖南省衡南县花桥镇为例

以湖南省衡南县花桥镇为研究样本区域,从三方面对农民责任观现状展开了社会调查和实证分析,并对如何进一步增强农民责任观提出了建议。     

An Implicit Iteration Process with Errors for a Finite Family of r-strictly Asymptotically Pseudocontractive Mappings

In this paper,we will establish several strong convergence theorems for the approximation ofcommon fixed points of r-strictly asymptotically pseudocontractive mappings in uniformly convex Banachspaces using the modiied implicit iteration sequence with errors,and prove the necessary and sufficient conditionsfor the convergence of the sequence.Our results generalize,extend and improve the recent work,in thistopic.

Capacity Constrained Transit Assignment with Common Lines

This paper proposes the use of absorbing Markov chains to solve the capacity constrained transit network loading problem taking common lines into account. The approach handles congested transit networks, where some passengers will not be able to board because of the absence of sufficient space. The model also handles the common lines problem, where choice of route depends on frequency of arrivals. The mathematical formulation of the problem is presented together with a numerical example. This revised version was published online in July 2006 with corrections to the Cover Date.

论文艺与宗教的共同特质

文艺与宗教在原始社会时期是混融在一起的。后来虽然在自己的进一步演化中走着各自不同的道路，但它们之间仍然具有许多共同的特质，主要表现在：1、都用感性直观的方式把握世界；2、都有追求人生哲学、人生终极关怀的目的；3、都属于社会意识形态。     

大学生英语写作常见错误分析

目前我国大学生的英语写作能力及写作水平普遍偏低，尚缺乏一定的书面交际能力，为此，重视英语写作课教学，加强对学生语言基础知识的训练，帮助他们分析并克服英语写作中的常见语言错误，是迅速提高他们的英语表达能力及交际能力，适应对外交际需求的当务之急。     

壮泰族群的渊源

壮泰族群的传统文化有许多共同点。这些共同点的形成,因缘于壮泰同源。两个民族的先民原来共同生活在今广西等地,一直到东汉时期。他们分离的时间,主要在三国两晋南北朝时期。分开以后,由于受到不同文化的影响,逐渐形成了两个不同的民族。这种情况,与远古时期生活在中国大陆和东南亚的三大民族集团的发展正相吻合。     

Nonlinear Time Series Analysis Since 1990:Some Personal Reflections

Abstract I reflect upon the development of nonlinear time series analysis since 1990 by focusing on five majorareas of development. These areas include the interface between nonlinear time series analysis and chaos,thenonparametric/semiparametric approach,nonlinear state space modelling,financial time series and nonlinearmodelling of panels of time series.     

Degree distribution of the greatest common divisor of polynomials over 𝔽q

We study the degree distribution of the greatest common divisor of two or more random polynomials over a finite field ??_q. We provide estimates for several parameters like number of distinct common irreducible factors, number of irreducible factors counting repetitions, and total degree of the gcd of two or more polynomials. We show that the limiting distribution of a random variable counting the total degree of the gcd is geometric and that the distributions of random variables counting the number of common factors (with and without repetitions) are very close to Poisson distributions when q is large. © 2005 Wiley Periodicals, Inc.
