Current and Future Problems of Capital Accumulation in the Chinese Pension System

The decree establishing a uniform system of basic pensions for employees in municipal and private enterprises, published by the State Council on 16 July 1997, reflects the Chinese Government's ultimate choice in favour of a partly private funded scheme to cover future pension needs. This article examines the reasons which led to this choice and asks how easy or otherwise it will be to find the capital to finance it. The authors believe that the partly private scheme is more advantageous than other methods and is right for China. Many issues, however, remain the focus of lively debate. In particular, a realistic coordination of individual and group accumulation is needed in order to avoid shortfalls in capital formation and the dangers of inadequate benefit provision. To safeguard the subsistence needs of former workers in state-owned enterprises, a system of equalization at national level is needed, and problems continue over how future pension insurance funds should best be managed.     

关于专利行政执法问题的探讨

专利行政执法在专利制度中具有重要的不可替代的作用。专利管理机关对专利纠纷的调处行为不是具体行政行为而属于居间仲裁。本文在进行理论和实务论证的基础上 ,提出以下立法建议 :当事人不服专利管理机关就专利纠纷所作处理决定向法院起诉时 ,仍应以纠纷的相对人为诉讼当事人 ;增加专利管理机关的执法手段 ;加大专利管理机关的处罚力度 ;对专利复审委员会就实用新型、外观设计的复审决定 ,当事人应有权启动司法程序 ;实用新型专利侵权诉讼中 ,专利权人应提交专利局就争议专利技术的专利性出具的检索报告 ,法院依据检索报告进行专利侵权的判定 ,不中止侵权诉讼。

草地早熟禾主要经济性状间的灰色关联分析

应用灰色关联分析方法研究了坪用草地早熟禾地上生物量、生殖枝数、生殖枝高、穗长、穗粒数、结实率等6个主要经济性状与种子产量以及各性状之间的关联程度。结果表明,各性状与种子产量之间的关联度大小依次为单位面积生殖枝数＞单位面积地上生物量＞生殖技高＞穗长＞结实率＞穗粒数。地上生物量对生殖校高、生殖枝数和穗长的影响较大。     

Feature selection based on distance correlation: a filter algorithm

Feature selection (FS) is one of the most powerful techniques to cope with the curse of dimensionality. In the study, a new filter approach to feature selection based on distance correlation is presented (DCFS, for short), which keeps the model-free advantage without any pre-specified parameters. Our method consists of two steps: hard step (forward selection) and soft step (backward selection). In the hard step, two types of associations, between univariate feature and the classes and between group feature and the classes, are involved to pick out the most relevant features with respect to the target classes. Due to the strict screening condition in the first step, some of the useful features are likely removed. Therefore, in the soft step, a feature-relationship gain (like feature score) based on the distance correlation is introduced, which is concerned with five kinds of associations. We sort the feature gain values and implement the backward selection procedure until the errors stop declining. The simulation results show that our method becomes more competitive on several datasets compared with some of the representative feature selection methods based on several classification models.     

皮亚杰的道德责任发生论及其教育意蕴

皮亚杰首次利用实验方法,从个体心理发展的微观角度,揭示了儿童的道德责任的发生过程和机制。道德责任是个体社会化的产物,经历了由他律的客观责任向自律的主观责任的进化。真正的道德责任产生于协作。皮亚杰的道德责任发生论对道德教育理论与实践的启示是:道德教育必须以自由为基础,充分利用学生的自主活动,才能教会学生负责。     

论中共二大提出"民族自决"的历史原因

本文认为,中共二大提出并不符合中国国情的民族自决主张,有其一定的必然性.这种必然性来自当时国际与国内、主观和客观诸种因素相互作用而产生的"历史合力".     

基于用户和基于项目结合的个性化推荐算法

这篇文章说明了一种新的推荐算法,结合基于用户的协同过滤算法和基于项目的协同过滤算法各自的优点,在新算法中,首先利用基于用户的协同过滤算法确定一定数量的邻居,以保证推荐的个性化,然后在确定的邻居数据集上利用基于项目的算法模型进行推荐。最后将这种新算法和基于项目的协同过滤算法进行比较,实验结果表明这种新算法只用一少部分部分的最相似邻居用户就能得到基于项目算法的推荐质量,而且要比基于项目的推荐更加个性化。
