自旋1/2量子受激转子中Planck常数调节的整数量子霍尔效应转变的有限尺寸标度分析

量子受激转子(quantum kicked rotor,QKR)是量子混沌研究中的重要模型之一。在自旋1/2的QKR中,调节等效Planck常数可以在动力学局域化相之间实现一系列相变,其形式与整数量子霍尔效应及其平台相变相似。研究这一相变的有限尺寸标度理论,并将其应用于自旋1/2的QKR模型。估计出相变的临界指数为ν=2.62(9),符合整数量子霍尔效应平台转变的普适类。     

试论公共信息资源商品化及其政府对策

公共信息资源作为一种带有公共性质的资源,在管理的过程当中极易产生公共信息资源商品化问题。公共信息资源的商品化,一方面既可能导致对公众利益的损害,另一方面也可能促使信息资源实现最大限度的开发与利用。作为公共信息资源的最大管理主体,政府应该区别对待公共信息资源两种不同的商品化趋向,采取相应的对策,扬长避短,使信息资源实现配置效益最大化。

中国现代中小学单项教学实验述论

教育方法的科学化是“五四”运动以来中国教育发展的一个时代主题，教育实验则是其实现的一个重要工具。在教学与课程实验领域，中小学单项教学实验最具持久和现实的影响力。它对教育教学改革的深入、教育的科学化与近代化历程的艰难曲折的探索，起到了重要的作用。     

云南护国首义档案

在中国近代历史上,曾经发生过一件大事,那就是1915-1916年的云南首义,护国讨袁。袁世凯背叛中华民国,复辟帝制,云南地处边陲之地首举护国讨袁义旗,组成三军出师川桂讨伐袁军最终胜利。作为89年前的那桩大事件,随着历史硝烟的淡去而渐渐隐去,但真实地反映护国反袁复辟帝制的正义之举的档案,却完整、系统地保存在云南省档案馆里,这就是首批登入“中国档案文献遗产名录”的《云南护国首义档案》。《云南护国首义档案》,均系-年形成,全部为汉文,最早保管在民国时期云南省政府秘书处内,共计191件。档案内容涉及中国南方及北方大部分地区,内容备至…     

Metropolis redux: the unique importance of library skills in informatics.

OBJECTIVES: The objective is to highlight the important role that librarians have in teaching within a successful medical informatics program. Librarians regularly utilize skills that, although not technology dependent, are essential to conducting computer-based research. The Metropolis analogy is used to introduce the part librarians play as informatics partners. Science fiction is a modern mythology that, beyond a technical exterior, has lasting value in its ability to reflect the human condition. The teaching of medical informatics, an intersection of technology and knowledge, is also most relevant when it transcends the operation of databases and systems. Librarians can teach students to understand, research, and utilize information beyond specific technologies. METHODS: A survey of twenty-six informatics programs was conducted during 2002, with specific emphasis on the role of the library service. RESULTS: The survey demonstrated that librarians currently do have a central role in informatics instruction, and that library-focused skills form a significant part of the curriculum in many of those programs. In addition, librarians have creative opportunities to enhance their involvement in informatics training. As a sample program in the study, the development of the informatics course at the Massachusetts College of Pharmacy and Health Sciences is included. CONCLUSIONS: Medical informatics training is a wonderful opportunity for librarians to collaborate with professionals from the sciences and other information disciplines. Librarians' unique combination of human research and technology skills provides a valuable contribution to any program.     

Disciplined freedom,branded authenticity,and dependable independence: how tensions enact flexibility in lifestyle blogging careers

Analyzing 219 blog posts from 52 self-employed women lifestyle bloggers in North America, this study shows how these digital professionals navigate tensions and communicatively constitute work flexibility. In their narratives, women bloggers employed tension management approaches such as reframing, continual connections, and reflective practice in response to tensions in enacting temporal–spatial, identity, and financial flexibility. Specifically, women followed oxymoronic constructions – disciplined freedom, branded authenticity, and dependable independence – to embrace and transform competing poles of fluidity?structure, authenticity?marketability, and independence?interconnection. Expanding work–life research to the self-employed digital labor context, this study responds to recent calls to uncover more-than tension management strategies in empirical settings and contributes to a tension-centered, contextual, and processual analysis of workplace flexibility construction.
