Disordered materials: a survey of amorphous solids

A brief historical perspective and a review of the current research on amorphous or glassy materials are presented. Glass formation by natural processes and by laboratory synthesis techniques is described. Recent efforts to characterize and model the atomic scale structure of amorphous phases are surveyed. The relation between amorphous and liquid states is emphasized in a discussion of thermodynamics and kinetics. The topic of crystal-to-glass transformation in the solid state and the related issue of crystal stability and melting are discussed.     

论精神障碍犯罪人行刑个别化的完善

精神障碍患者犯罪是遗传、疾病以及各种社会因素综合作用下产生的结果,其犯罪行为的发生具有一定的特殊性。因此对其采用一般性的刑罚方法难以达到理想的教育改造效果。依据精神障碍犯罪人的自身特点,在行刑个别化、行刑社会化理念的指导下设计、完善刑事处遇措施以帮助精神障碍犯罪人驱除犯罪原因,重新融入社会生活。根据具体案件的差异将精神障碍犯罪人刑事个别化处遇完善分为社区矫正制度完善与监狱矫正制度完善。     

我国中部6省人口-土地城市化失调特征及空间格局研究

基于ArcGIS和GeoDa软件平台,结合统计学中的变异系数方法,从时间、空间及关联性的视角分析我国中部6省81个地级市2006 ～2011年人口-土地城镇化失调特征空间格局.结果表明,中部地区城市人口城镇化和土地城镇化发展存在普遍的不协调现象,2006 ～2011年中部地区81个地级市的人口-土地城镇化变异系数在空间上存在较明显的负的空间自相关,不论是整个中部地区还是各个省份内部,人口城市化和土地城市化失调程度的区域差异明显,2006～2011年,中部地区人口-土地城市化失调区域差异有减小的趋势,失调态势有所改善.     

Database systems

Database systems, computer systems that are principally devoted to the management of large amounts of data, are becoming more and more important to the operation of many enterprises. This article surveys the technology of database software and hardware, describing some of the principal issues related to the user's view of data, sharing, concurrent access, security, and integrity.
