"凤凰"自比"黄鹤"好--论李白《登金陵凤凰台》的超越性

历代对崔颢<黄鹤楼>的评价都非常高,而对李白<登金陵凤凰台>多有贬低.其实崔诗开篇滞缓重复,在精神上是消极的、悲观的,是个人之愁.李诗在句法上概括精炼;在章法上抒情怀古巧妙地结合;在境界上积极奋发、乐观向上,是时代精神的代表.所以李诗不论是艺术性还是思想性都胜于崔诗,即所谓"青出于蓝,而胜于蓝."     

论新世纪中国哲学精神走向

新世纪的中国需要什么样的哲学精神?目前学术界存在三种观点"启蒙运动补课论";"传统文化本位论";"后现代意识论".这三种观点都是片面的,但它们分别反映了中国社会目前所存在的前现代、现代和后现代的多种矛盾中的某一方而.新世纪中国所需要的哲学精神,不是对上述三种观点中某一种的简单认同,也不是简单抛弃,而是对上述三种观点进行有机整合,提炼出一种能够真正支撑中国特色社会主义现代化模式的哲学精神.     

银行个人贷款审批规则库的知识求精

鉴于个人贷款在银行业务中的比重不断上升,对个人贷款申请进行审批显得格外重要。由于初始规则库常常存在知识不完全或不一致等问题,所以需要规则库修正,即规则库知识求精。现以日本银行个人贷款审批规则库为例,采用神经网络技术,利用个人贷款审批的历史数据,对规则库进行知识求精。结果表明,求精后的规则数量减少了,而分类准确率却有很大的提高。     

"五四"以来中国文学的雅俗研究

"五四"以来,中国文学的雅俗研究尽管有了很大的进展,但是雅俗的区分仍然显得混乱.传统雅俗研究中的困惑与矛盾,根源于单一的思维方式与理论指导.在意识形态理论中,往往将雅俗进行简单的二元对立,容易忽视二者之间互相转化的运动关系.马克思主义的艺术生产理论把艺术当作一种生产、一种动态的活动,能在更为广阔的社会生活层面、从生产(艺术创作)--消费(艺术接受)的动态循环过程来对雅俗问题进行研究.在新的时期,以马克思主义的艺术生产理论为主、其他理论为补充的多角度综合研究,将成为中国文学雅俗研究的新趋势.     

论唐太宗对宫体诗的改造

宫体诗风行梁、陈、隋三代,至唐贞观时,唐太宗依据儒家政教文学观对其进行了全面改造,变其轻艳柔媚为雅正典丽,以使其更好地为新朝服务。他认为儒学才是经邦治国之至道,是创业守成、作训垂范的思想支柱。儒家“诗言志”的思想必然取代元朝以来所形成的“诗缘情”学说。儒家思想复归,引起了初唐诗歌使命的转变,贞观诗坛在一定程度上恢复和实践了诗歌“劝百讽一”的讽谏使命,逐渐走向注重诗歌辞采的典丽高雅,把诗歌从宫廷引向更为广阔的天地,提倡南北文风的融合,主张文质并重,以文学服务于政教又不失其艺术特色。     

Stubbornness,Power, and Equilibrium Selection in Repeated Games with Multiple Equilibria

Axelord’s [(1970), Conflict of Interest, Markham Publishers, Chicago] index of conflict in 2 × 2 games with two pure strategy equilibria has the property that a reduction in the cost of holding out corresponds to an increase in conflict. This article takes the opposite view, arguing that if losing becomes less costly, a player is less likely to gamble to win, which means that conflict will be less frequent. This approach leads to a new power index and a new measure of stubbornness, both anchored in strategic reasoning. The win probability defined as power constitutes an equilibrium refinement which differs from Harsanyi and Selten’s [(1988), A General Theory of Equilibrium Selection in Games, MIT Press, Cambridge] refinement. In contrast, Axelrod’s approach focuses on preferences regarding divergences from imaginary outmost rewards that cannot be obtained jointly. The player who is less powerful in an asymmetric one-shot game becomes more powerful in the repeated game, provided he or she values the future sufficiently more than the opponent. This contrasts with the view that repetition induces cooperation, but conforms with the expectation that a more patient player receives a larger share of the pie.      

词的雅化与音乐演进关系

对宋英宗、神宗、哲宗三朝期间的乐府制度、音乐理论、民间音乐等与词乐密切相关的诸因素的源流演变过程进行分析,从研究的角度理清唐宋词与音乐演进发展的脉络,说明音乐对词的特性及词体演变有显著影响。     

从“精细化”到“精准化”:乡村公共服务供给的逻辑转向

“项目进村”是国家力量嵌入乡村社会治理的重要变量，也是重塑国家资源分配体制的重要渠道。现行资源下乡体制下，乡村公共服务“项目制”供给构筑了一整套“精细化”的公共产品分配、管理和输送体系。这在确保国家意图高效率投射乡村的同时，也因过度技术性的流程把控削减了对乡村实际面向的关照，从而出现产品供需脱节、服务目标替代、内生服务能力削弱等“公共服务弱化”的意外后果。对此，厘清涉及“需求识别”“定向配置”“长效管理”等价值的公共服务“精准化”供给逻辑，对改善“项目进村”效果具有重要现实意义。时下乡村公共服务“精准化”供给不仅应推动现有服务资源供给评价方式和多元参与模式的改良，也应促进公共服务数字赋能和内生机制的革新，实现“过程精细”和“结果精准”的有机结合。     

Bootstrap Methods for Markov Processes

The block bootstrap is the best known bootstrap method for time‐series data when the analyst does not have a parametric model that reduces the data generation process to simple random sampling. However, the errors made by the block bootstrap converge to zero only slightly faster than those made by first‐order asymptotic approximations. This paper describes a bootstrap procedure for data that are generated by a Markov process or a process that can be approximated by a Markov process with sufficient accuracy. The procedure is based on estimating the Markov transition density nonparametrically. Bootstrap samples are obtained by sampling the process implied by the estimated transition density. Conditions are given under which the errors made by the Markov bootstrap converge to zero more rapidly than those made by the block bootstrap.
