多源模型的新进展

本文总结了高能核—核碰撞的多源模型自1987年提出到1990年以来的主要进展,着重介绍多源模型的基本物理思想及其在两种不同方案下的发展动态.通过与最新实验数据比较,说明多源模型能够成功地解释高能重离子碰撞的整体性质.     

高校建设应法治德治并举

为深入贯彻依法治国和以德治国相结合的治国方略,高校建设也应依法治校与以德治校并举,这是由当前教育中存在的问题,教育的目标机制决定的。实现这一治校方略应分别制定举措,并将两者紧密结合起来,不能忽视其中任何一个方面,要做到两手抓、两手都要硬。     

The dilemma of recognition: Administrative categories and cultural diversity

Governments around the world combat inequality by means of group-specific redistribution. Some pursue redistribution that benefits groups, but also wish to avoid accentuating or even recognizing group distinctions. This poses a dilemma that they try to resolve by adjusting the category system used to target redistribution. There are three types of adjustment: accommodation (the multicultural approach), denial (the ideal-typical liberal solution), and replacement (a compromise). In replacement the targets of redistributive policies are constructed to avoid accentuation or recognition of inconvenient group distinctions, but still allow redistribution that benefits these groups. Replacement is increasingly in demand around the world because the disadvantages of multiculturalism are becoming apparent while denial is hard to sustain in the face of group inequality. The actual effect of replacement is little researched and less understood, however. Does it resolve the dilemma of recognition? Two examples–India and Nigeria–where replacement has been tried ever since the 1950s cast doubt on its viability.     

Multiple imputation of missing data with ante-dependence covariance structure

A controlled clinical trial was conducted to investigate the efficacy effect of a chemical compound in the treatment of Premenstrual Dysphoric Disorder (PMDD). The data from the trial showed a non-monotone pattern of missing data and an ante-dependence covariance structure. A new analytical method for imputing the missing data with the ante-dependence covariance is proposed. The PMDD data are analysed by the non-imputation method and two imputation methods: the proposed method and the MCMC method.

运河文化的特质及其对当前经济社会发展的启示

运河文化属带状型地域文化,其特质属商业文化。认定此点的依据有三:一是运河贯通带动商贸发展,增加官府税收;二是促进城镇经济的发展;三是打破封闭的农业自然经济,孕育资本主义的萌芽,推动中外经济和文化交流。考察运河文化的兴衰,留给我们的启示很多:从其与当时占主导地位的农业文明关系看,二者并非绝对排斥,可以融合。在社会主义初级阶段,不能简单地对尚有很强生命力和发展空间的农业文明一概排斥,应以商改农,抓住机遇,扩大交流;从其与城市建设角度说,应延续历史文脉,注意保护和发展的关系,既遵循规律又要考虑超越式发展,提升城市文化品位;从其与区域经济发展看,一是区域经济发展既需外力,更需内力;二是应以旅游带动商贸;三是抓南水北调机遇,未雨绸缪,选准切入点和突破口。
