收费政策下贫困研究生相关问题的界定与资助对策

研究生收费政策不仅加剧了研究生的原发性贫困,而且引发了研究生的再生性贫困。对贫困研究生从不同的标准和内容进行准确界定,不仅十分必要,而且也有助于更科学地对其进行资助。对贫困研究生进行资助应注意保证研究生公平享有“奖、助、勤、贷”的相关政策,建立国家、学校、院系和导师四位一体的资助体系,完善研究生突发事件的预警和自助机制。     

乡村人居环境中家畜空间特征及再生设计研究 ——以湘南地区为例

家畜空间作为乡村人居环境中的重要组成部分,对乡村环境的村容村貌有着极为重要的影响。为了优化乡村人居环境,构建乡村生态文明,文章基于家畜空间的基本类型特征与再生设计的基本原则,对湘南地区的家畜空间与人居建筑的空间关系进行剖析,总结出家畜空间的集群式和散点式分布特点。在此基础上,对湘南地区家畜空间再生设计的实际案例进行了深入研究,尤其考虑其人性化因素,即装饰材料生态化,空间布局人性化以及使用功能多样化,实现了废弃家畜空间的功能再生、形式再生,促进了乡村废弃建筑的重生和乡村经济新增长。最终对乡村生态文明,特别是人居环境中家畜空间的可持续发展提供重要的参考和借鉴。     

儒学在近代的历史命运:败也西学,成也西学

儒学在晚清、民国时期的历史轨迹,经历了解体与重构的剧烈变化。在经济社会制度现代转型的制约下,儒学在抵御西学的冲击中连连失败,教育、政治和伦理等三大功能皆失,无可奈何花落去,走向衰亡。但儒学的包容和嬗变本性,配之以那些学贯中西的精英们的研究和倡导,巧借民族危亡和文化民族主义兴盛的历史机缘,又在融会西学和顺应现代化潮流中得以新生,实现了儒学历史演进中第三次重大变革。但毕竟儒学所依存的经济社会体制和小农式的日常生活状态发生了质的变化,儒学原有的三大功能不可能有用武之地,有形变为无形,只能作为一种文化资源,去张扬其人文精神。     

A geometric approach to transdimensional markov chain monte carlo

The authors present theoretical results that show how one can simulate a mixture distribution whose components live in subspaces of different dimension by reformulating the problem in such a way that observations may be drawn from an auxiliary continuous distribution on the largest subspace and then transformed in an appropriate fashion. Motivated by the importance of enlarging the set of available Markov chain Monte Carlo (MCMC) techniques, the authors show how their results can be fruitfully employed in problems such as model selection (or averaging) of nested models, or regeneration of Markov chains for evaluating standard deviations of estimated expectations derived from MCMC simulations.

The Redevelopment of Bus Depots: A Transaction Cost Economic Analysis of a Change in the Use of Land in Hong Kong

This is a pioneering study on bus depots based on a review of the English-language literature on or related to them, which is motivated by the prevalence of real estate projects using the land of the former depots. The review is followed by some conjectures about the transaction cost advantages of bus depot sites as a source of development land and examines the hypothesis that redevelopment projects using former bus depots, compared to other uses, in Hong Kong are more easily approved under the statutory planning system. The literature review found that bus depots have attracted much academic attention, although research angles were conditioned by different social perceptions of bus depots. The empirical results of this case study did not reject the hypothesis. The limitations and implications of the study are discussed.     

敦煌艺术视听化转换及其现代化

视听化是文化在全球化、信息化进程中的重要表现方式。敦煌艺术也不例外,它的视听化再生是这一文化现象推动下的必然结果。1979年甘肃敦煌艺术研究院成功推出大型歌舞剧《丝路花雨》,在全球热演超过1300场。在它的引领下,敦煌艺术出现了视听化再生热潮,并取得不俗成就。但在这股浪潮中也存在不少问题亟待解决。通过对敦煌艺术视听化转换中得与失的深入分析,尝试对更合理的全面再生提出自己的见解。     

Efficient use of exact samples

Propp and Wilson (Random Structures and Algorithms (1996) 9: 223–252, Journal of Algorithms (1998) 27: 170–217) described a protocol called coupling from the past (CFTP) for exact sampling from the steady-state distribution of a Markov chain Monte Carlo (MCMC) process. In it a past time is identified from which the paths of coupled Markov chains starting at every possible state would have coalesced into a single value by the present time; this value is then a sample from the steady-state distribution.Unfortunately, producing an exact sample typically requires a large computational effort. We consider the question of how to make efficient use of the sample values that are generated. In particular, we make use of regeneration events (cf. Mykland et al. Journal of the American Statistical Association (1995) 90: 233–241) to aid in the analysis of MCMC runs. In a regeneration event, the chain is in a fixed reference distribution– this allows the chain to be broken up into a series of tours which are independent, or nearly so (though they do not represent draws from the true stationary distribution).In this paper we consider using the CFTP and related algorithms to create tours. In some cases their elements are exactly in the stationary distribution; their length may be fixed or random. This allows us to combine the precision of exact sampling with the efficiency of using entire tours.Several algorithms and estimators are proposed and analysed.     

国家与市场的双重塑造:工人阶级的解体和重建

在单位制度的基础上依附于国家的传统工人阶级,其计划体制中的权利被剥夺,同时市场体制中的权利远未兑现,利益受损的工人以集体抗争的形式来表达自身强烈的不满,在此过程中工人阶级开始获得自主性的权利意识并成为劳工力量重建的重要资源。劳工力量重建既是一个工人阶级的内部整合过程,也是一个工人与国家之间关系重构的过程,而两者的相遇则孕育着国家制度成长的契机。
