Looking for Aristotle

Although Aristotle was often portrayed during the early modern period, his imagined appearance varied widely. When modern interpreters try to impose definitive meanings on pictures, they run the risk of overlooking symbolic resonances which can be just as significant as direct representation.     

研究生群体的求职问题研究

研究生群体是包括硕士研究生与博士研究生在内的群体,随着国家的扩招政策由本科及以下向研究生的延伸,该群体在找工作时开始面临巨大压力。研究生群体求职问题在微观层次上的原因从根本说是由“职位供需的内卷化”造成的。而内卷化造成的求职困境问题需要社会资本这样的替代性资源来缓解。本文通过上海和沈阳两地高校的个案访谈在微观层次上较为深入地探讨了研究生群体在求职过程中对各种资源尤其是社会资本的运用以及实际的求职效果。     

Looking for a general for some modern major models

Computer climate models are some of the most complex scientific structures ever conceived. Consisting of hundreds of thousands of equations and running on supercomputers capable of trillions of operations per second, they chart the evolution of past and future climates across thousands of years. These simulations are breathtaking in their qualitative detail and vastly ambitious in their quantitative exactitude. However, their progress has recently been challenged by the very size and complexity of the models, factors that are also paralleled in the communities of scientists that build them. This complex co-evolution of computers and scientific communities gives us insight into the promise and limits of sciences driven by exponential increases in computing power.     

Looking to the Internet for models of governance

If code is law then standards bodies are governments. This flawed but powerful metaphor suggests the need to examine more closely those standards bodies that are defining standards for the Internet. In this paper we examine the International Telecommunications Union, the Institute for Electrical and Electronics Engineers Standards Association, the Internet Engineering Task Force, and the World Wide Web Consortium. We compare the organizations on the basis of participation, transparency, authority, openness, security and interoperability. We conclude that the IETF and the W3C are becoming increasingly similar. We also conclude that the classical distinction between standards and implementations is decreasingly useful as standards are embodies in code – itself a form of speech or documentation. Recent Internet standards bodies have flourished in part by discarding or modifying the implementation/standards distinction. We illustrate that no single model is superior on all dimensions. The IETF is not effectively scaling, struggling with its explosive growth with the creation of thousands of working groups. The IETF coordinating body, the Internet Society, addressed growth by reorganization that removed democratic oversight. The W3C, initially the most closed, is becoming responsive to criticism and now includes open code participants. The IEEE SA and ITU have institutional controls appropriate for hardware but too constraining for code. Each organization has much to learn from the others.     

Narratives of quantum theory in the age of quantum technologies

Quantum technologies can be presented to the public with or without introducing a strange trait of quantum theory responsible for their non-classical efficiency. Traditionally the message was centered on the superposition principle, while entanglement and properties such as contextuality have been gaining ground recently. A less theoretical approach is focused on simple protocols that enable technological applications. It results in a pragmatic narrative built with the help of the resource paradigm and principle-based reconstructions. I discuss the advantages and weaknesses of these methods. To illustrate the importance of new metaphors beyond the Schrödinger cat, I briefly describe a non-mathematical narrative about entanglement that conveys an idea of some of its unusual properties. If quantum technologists are to succeed in building trust in their work, they ought to provoke an aesthetic perception in the public commensurable with the mathematical beauty of quantum theory experienced by the physicist. The power of the narrative method lies in its capacity to do so.     

在生活中寻找数学——探析小学数学生活化教学策略

《数学新课程标准》中明确提到:"数学教学是数学活动的教学,数学教学要和学生的生活实际紧密联系在一起,立足于已有的生活经验,让学生和数学过程相亲近;要重视立足于学生的实践经验和已有知识学习和理解数学。"所以,小学数学教师在教学中应和学生的生活实际相联系,把生活资源充分挖掘出来,积极探析生活中的相关信息,按照数学从生活中来而又服务于生活的新理念,把经验数学化、数学问题生活化,为学生提供更多的机会,让其从周围熟悉的事物中学习和探究数学。     

科研人员的情商探究

在知识经济时代,科研人员无疑是知识和财富的主要创造者,他们的创造能力直接体现在他们的创造水平上。因此,对个体智力重要组成部分的情绪智力的研究,是当前一个亟待解决的理论和实际问题。本文对此进行了初步而系统的探讨。     

一种星地量子密钥通信仿真平台

针对星地量子密钥通信空间环境复杂、国内暂不具备实物实验条件的现状,提出一种用于量子密钥通信的计算机仿真平台设计.该平台具有仿真星地量子密钥通信中APT及单光子传输捕获过程的能力和自适应光学对传输畸变波前的修正能力.使用此平台,得到了星地量子密钥通信跟瞄精度、自适应光学对畸变波前的修正及单光子捕获概率、误码率的合理仿真结果,证明此仿真平台对实际系统的设计具有参考意义.     

透视企业客户关系管理中的关系技术

解读我国首例软件捆绑销售案

2006年12月13日,上海高级人民法院对一起计算机软件著作权侵权纠纷案作出终审判决,认为原告为将其开发的应用软件捆绑在自己生产的产品上使用而专门设计的输出文件格式,已经超出了《著作权法》规定的技术保护措施的范围,被告破解该软件输出数据文件格式的行为不属侵权行为。本案是自我国2001年修改《著作权法》以来,第一起涉及利用技术保护措施实现产品捆绑销售的案件。该判决对今后类似案件的审理,以及未来相关产业的有序发展具有深远的指导意义。     

Looking Backward and Forward at the Internet

This article reviews accounts of the origins and growth of the global Internet with an interest in their implications for the future. Many accounts take overly restricted views of technical development. For instance, the Internet is often seen simply as the outgrowth of U.S. Defense Department work and popular enthusiasm. Recent interdisciplinary studies of technology present a more complex picture of how innovations are developed. They highlight technical alternatives, contributions of diverse groups, variety in meanings of technologies, and the overall surprising character of technology development. They suggest that the Internet has multiple origins and numerous particular reasons for its spread. Current discussions of the entry of Internet technologies into consumers' homes and the convergence among computing, media, and telecommunications enterprises represent examples of more complex accounts of technology development. Such accounts will likely provide more powerful bases for policy, management, and design.
