商周"鼎"观念的二元结构

鼎是商周礼器中的代表性器物.在它身上,既凝聚了现实生活的世俗性,又饱含古人的文化想象.本文从其创制入手,通过分析上古文献,阐述商周时代鼎在人们心目中的"神圣/世俗"二元结构存在.

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.     

刘渊感生神话的历史形成

《晋书》卷101《刘元海载记》云:“豹(刘渊之父)妻呼延氏,魏嘉平中祈子于龙门,俄而有一大鱼,顶有二角,轩鬐跃鳞而至祭所,久之乃去。巫觋皆异之,曰:‘此嘉祥也。’其夜梦旦所见鱼变为人,左手把一物,大如半鸡子,光景非常,授呼延氏,曰:‘此是日精,服之生贵子。’寤而告豹,豹曰:‘吉征也。吾昔从邯郸张冏母司徒氏相,云吾当有贵子孙,三世必大昌。仿像相符矣。’自是十三月而生元海,左手文有其名,遂以名焉。”该神话以神秘主义的方式对后汉建立者刘渊(即刘元海)的出生进行了详尽生动的表述,堪称古代政治感生神话的一个典型例子。《晋书》为唐初史…     

日本过疏地区开发方式及政策的演变

战后日本区域经济发展呈明显的两极分化态势。一方面是大量的经济功能和财富聚集在以东京为首的三大城市经济圈,另一方面是边远过疏地区的人口急剧减少和经济衰退。日本纠正地区差距对策的重点是扶持和援助过疏地区的发展。本文重点论述过疏地区治理政策中以基础设施建设和公共投资为特征的开发方式的局限性,同时对20世纪90年代学术界提出的以过疏地区为主体的内生式发展方式进行分析,最后梳理近年日本政府新实施的且对过疏地区影响很大的农业收入直接补贴政策。     

福田内阁前途多舛

福田康夫2007年9月23日毫无悬念地当选为自民党第22任总裁,25日被国会推举为第91任首相并旋即组建新内阁。至此,因安信晋三首相9月12日突然辞职造成的政治真空得以填补,中断的临时国会恢复运转,一度陷入"山重水复"困境的日本政局似又转为"柳暗花明"。2006年曾以高龄为由退出自民党总裁竞选、本以为再也无望问鼎首
