从"唐人选唐诗"看王昌龄在唐代诗坛地位的变迁

“唐人选唐诗”录王昌龄诗歌作品的情况反映出唐代不同时期人们对王昌龄诗歌接受态度及其在唐代诗坛地位的升降变迁。总体而言 ,昌龄因其五言古诗对盛唐诗风的开拓之功而受到当时选家普遍重视 ,有“诗家夫子”之称 ,中唐以后选家则独重昌龄七言绝句 ,虽以“七绝圣手”誉之 ,但其诗歌地位已非显著。文章同时指出 ,作为古代诗歌批评的一种特殊形态 ,唐诗选本所蕴含的诗学价值应受到重视 ,成为唐诗学研究的一个方向     

Optimal scaling of Metropolis algorithms: Heading toward general target distributions

The authors provide an overview of optimal scaling results for the Metropolis algorithm with Gaussian proposal distribution. They address in more depth the case of high‐dimensional target distributions formed of independent, but not identically distributed components. They attempt to give an intuitive explanation as to why the well‐known optimal acceptance rate of 0.234 is not always suitable. They show how to find the asymptotically optimal acceptance rate when needed, and they explain why it is sometimes necessary to turn to inhomogeneous proposal distributions. Their results are illustrated with a simple example.     

Micromomentary movement and the deconding of face and body cues

A new version of the Profile of Nonverbal Sensitivity Test (PONS)—a standardized test of sensitivity to nonverbal cues—was developed to determine the effects of five levels or sequences of micromomentary movement on accuracy in decoding nonverbal face and body cues, presented for 125 microseconds (msecs). The five sequences were: backward movement, partially backward movement, no movement, partially forward movement, and fully forward movement. Two versions of this test—the Test of Micromomentary Movement Effects (TOMME)—were administered to two samples of female high school and college students. The results, averaged over face and body cues, showed that as the movement sequences more closely approximated the fully forward sequence, decoding accuracy increased. These results, showing the benefits of adding properly sequenced information at split second (42 msec) exposures, not only support the findings of previous researchers that micromomentary facial affect displays may be helpful in decoding nonverbal facial cues, but also suggest that micromomentary movements may be important for decoding body cues as well.

清初"外藩蒙古十三旗"杂考

本文依据清崇德二年蒙古文档案澄清了清代史籍中有关"外藩蒙古十三旗"的说法,解决了清初在内蒙古设旗和朝贡方面的一个疑难问题.指出了<旧满洲档>在记载清初蒙古牛录和户数上的错误和蒙古文档案的价值,还附带讨论了察哈尔部和硕亲王额哲旗不在"外藩蒙古十三旗"内和"外藩二十七旗"及"外藩四十九旗"的问题.     

Concepts,Theory, and Techniques PRINCIPLES OF MULTIOBJECTIVE OPTIMIZATION*

This paper attempts to isolate and analyze the principal ideas of multiobjective optimization. We do this without casting aspersions on single-objective optimization or championing any one multiobjective technique. We examine each fundamental idea for strengths and weaknesses and subject two—efficiency and utility—to extended consideration. Some general recommendations are made in light of this analysis. Besides the simple advice to retain single-objective optimization as a possible approach, we suggest that three broad classes of multiobjective techniques are very promising in terms of reliably, and believably, achieving a most preferred solution. These are: (1) partial generation of the efficient set, a rubric we use to unify a wide spectrum of both interactive and analytic methods; (2) explicit utility maximization, a much-overlooked approach combining multiattribute decision theory and mathematical programming; and (3) interactive implicit utility maximization, the popular class of methods introduced by Geoffrion, Dyer, and Feinberg [24] and extended significantly by others.     

Vendor Selection with Bundling*

Product bundling has become increasingly prevalent not only in consumer goods but also in the industrial sector. We study a purchasing problem in which a buyer must obtain necessary numbers of various stock items from a variety of vendors who charge different prices, have limited capacities and different levels of quality, and offer bundled products at discounted prices. We examine relationships among different bundling scenarios and show that the most general scenario is one in which free items are given to the buyer when sufficient quantities are purchased. We develop a mixed integer linear program that finds the purchasing strategy for the buyer that minimizes the total purchase cost. We present computational results which indicate that the problem is very tractable to solve optimally on a personal computer with standard optimization software. Finally, three extensions of the model are discussed.

中国的东北和日本的东北——对中日构筑“大东北经济圈”的思考与建议

2006年10月安倍首相上任伊始，便决定访问中国，展开了“破冰之旅”，结束了中日之间自2001年小泉上台由于参拜靖国神社引发的对立和矛盾，此后“融冰之旅”、“迎春之旅”使中日战略互惠关系不断向前推进。胡锦涛总书记的“暖春之旅”使两国战略互惠关系进入全面升级阶段。在上述氛围推动下，两国的经贸也不断取得突破，中日贸易超过美日贸易，中国成为日本第一大贸易伙伴。随着两国在各个领域的相互依赖不断加深，以区域合作为纽带、以友好城市发展为拉动，两国的地方交流也出现蓬勃发展势头。尤其是我们的东北振兴战略持续深化，使两国在东北地区的各种合作不断增加，学术、经济和企业界甚至发出了打造“中日大东北经济圈”的热切呼声。从中日经贸互动和地方国际合作背景来看，随着两国在东北地区合作的不断深入，中日构筑“东北经济圈”不但具有可能性而且时机日渐成熟。
