赵树理、高晓声农村题材小说之异趣

因创作立场、创作目的、时代环境、个性才情等因素之差异,赵树理、高晓声之农村题材小说呈现出一系列不同的创作风格,具体表现为:赵树理的小说采用的是散点透视的方法,对工作中所遇到的问题予以诗意的言说,写的是凡人大事,文笔简约,风格明丽欢快;高晓声则以追踪反映的方式,致力于对农民心灵世界的探索,多为奇人奇事,善于细节描绘,风格幽默,喜中有泪.     

Ruin Probabilities for the Perturbed Compound Poisson Risk Process with Investment

In this article, we consider the perturbed compound Poisson risk process with investment incomes. The risk reserve process is perturbed by an independent Brownian motion and the surplus is invested at a constant force of interest. We investigate the asymptotic behavior of the ruin probability as the initial reserve goes to infinity. Bounds and time-dependent bounds are derived for the ultimate ruin probability and the probabilities of ruin within finite time, respectively. We also obtain an explicit expression for the Laplace transform of the ultimate ruin probability.     

中国当代文学批评史上的“中间物”——以王晓明、葛红兵、谢有顺为例

新时期以来,人本主义批评观在中国获得长足发展.王晓明、葛红兵、谢有顺分别以"精神"、"身体"、"意义"为核心,提出了他们各自所代表时代最具典型意义的人本主义批评观.然而他们在急切地呼唤人性的同时往往滑向功利,使得批评立场与批评实践之间发生了分裂和悖离.在他们身上深刻地体现了历史"中间物"的特性.本文试图从他们三人的批评观以及批评实践出发,理顺他们之间的精神脉络,探讨他们批评观的异同及成败,进而展示人本主义批评观在当代中国的发展进程.     

城市化背景下的农民人格嬗变及对犯罪的影响

目前,我国已经步入了城市化发展的"快车道",城市化的核心问题是农村人口的城市化,即农民向市民的角色转换.农民向市民的转化过程实质上是农民人格不断嬗变、逐步过渡到市民人格的过程,由于嬗变的自发性和城市化消极因素影响而衍生的不良人格嬗变是诱发犯罪的潜在因素,控制、减少不良的人格嬗变可减少犯罪的发生.

微分方程在构造微分中值命题的辅助函数中的应用

众所周知,Lagrange定理、Cauchy定理[1]及其它许许多多微分中值命题的证明均借助于构造一个适当的辅助函数。然而,如何作辅助函数,如同作几何证明中的辅助线,需要较高的技巧,无一定法则可循,这给教学带来了难处。文[2]给出了一种辅助函数的“统一”构造法,只需按照一套固定的程序即可。本文利用简单微分方程的解构造出中值问题的辅助函数,从而得到寻求辅助函数的一种新方法。

A preliminary inquiry on the problem of unplanned (extra-quota) second births

The resurgence of child births in China in 1981 was marked by a decline in the multiparity birth rates and a drastic rise in the rate of unplanned 2nd births, resulting in unplanned 2nd births outnumbering multiparity births. The aim of this investigation was to find the objective and subjective causes for the unplanned 2nd births and explore ways to bring them under strict control. In the countryside there are loud voices that give insufficient labor as their reason for wanting 2nd births. An analysis of 923 cases of unplanned 2nd births in connection with the economic conditions of the families, the sex of the 1st births, intervals between the births, and the parents' cultural level shows that 61.87% of the total number of families suffered a decline in their income. The effect of the sex of the 1st birth over the 2nd birth varies with different localities. Among those having unplanned births, illiterates accounted for more than 35% in Nanzheng and Yanchuan counties and over 20% in Mianxian and Wubao counties. The current rise in 2nd births is due mainly not to economic reasons but to social and psychological reasons. To effectively hold down 2nd births under the current conditions, the following suggestions are offered: 1) step up propaganda and education work to gradually raise people's consciousness for practicing family planning, 2) family planning measures of economic restriction and reward must be implemented, 3) on the basis of enforcing the new marriage law, late marriage should be promoted, 4) a population tax should be imposed, and 5) social insurance for the elderly should be enlarged.     

A historical demography of Chinese migration

Trends in international migration from China are analyzed from historical times to the present. "The study will involve discussions about the nature of migration and the different forms it took in five different stages, in the light of 1) changes in motivation, 2) type of migration, and 3) the distribution of the out-going population."
