企业网络安全问题与对策浅析

随着计算机网络技术的发展，企业的信息化程度越来越高。但从整体看，我国企业的网络信息安全还存在很多问题．网络安全工作明显滞后于网络建设。     

随机-无标度统一混合演化网络模型

根据实际网络的特点,提出了一个随机-无标度统一混合演化网络模型.通过引入一个调节参数p将随机演化网络与(Barabási-Albert)无标度网络统一起来.理论计算和计算机模拟表明,当调节参数p从1变化到0时,网络结构实现了从随机演化网络到BA无标度网络的连续过渡.

邓小平的科技观新论

邓小平关于科学技术的理论是邓小平建设有中国特色的社会主义理论的重要组成部分 ,也是马克思列宁主义、毛泽东思想理论宝库的重要组成部分。它主要包括科技与生产力、科技与人才、科技与教育及科技与科技开放等基本思想 ,它是推动我国科技进步和经济发展的理论基础。     

费恩伯格的技术批判理论的内涵

新一代法兰克福学派在美国的主要代表安德鲁·费恩伯格在分析以往技术理论不足的基础上提出了技术批判理论,从传统法兰克福学派抽象地批判社会转向对社会中最为常见的技术现象的批判.从理论基础、价值目标、理论内核、方法论框架和批判主题等方面对这一理论展开了剖析,其中理论基础是对传统技术哲学"接受还是放弃"技术的两难困境的分析,价值目标是马克思主义的人的解放,理论内核是民主的理性化,使用的是社会建构论研究技术的方法论框架,批判主题是告别敌托邦.     

Time,Stress and Intellectual Engagement in Academic Work: Exploring Gender Difference

This article is based on a pilot study that examines the effects of recent organizational and public policy changes on Canadian academics' work practices and academic culture. It explores the differences between the use of online technologies by women and male academics in managing these effects. It interprets the complex and often contradictory findings of the study through the lens of time theorization, and speculates about the broader cultural implications of academics' changing work practices, including the possibility of a gestalt shift in the identity of the university, less as a site of research and reflection on society and increasingly as a productive and efficient part of the economy.     

关于北仑“科教兴区”的几个问题

The Prospects for Digital Radio

Digital audio broadcasting is a major innovation in radio, one that is at its most advanced in Europe. It has the potential to deliver high-quality audio reception and to increase significantly the capacity of the radio spectrum, with the possibility of an expansion of both the range and diversity of radio programming. Nevertheless, in the UK and elsewhere it remains relatively unknown and under-adopted in comparison with other consumer technologies like digital television. This article examines the origins of digital radio, and considers how this technology is expected to become a mass communications technology, eventually supplanting analogue radio. However, in its present form, there is little that is novel currently being offered on digital radio, and the economic and political contexts in which it is being developed may encourage further concentration of ownership and reduce diversity of choice in listening. Unlike previous innovations then, such as FM broadcasting, there appear to be few compelling advantages of digital radio that will persuade listeners to adopt this new technology. If this new technological system is to succeed, alternative uses must be found for it, and one area for which it might be suited is mobile data communications. The article concludes by suggesting that this might mean that radio becomes of secondary importance to this potentially lucrative application of digital audio broadcasting technology.     

专利法上的抽象思想与具体技术——计算机程序算法的客体属性分析

程序算法的可专利性是计算机程序专利保护制度的一个核心问题。文章从专利客体从“产品”向“方法”拓展的历史过程出发,揭示专利法区分抽象思想和具体技术的传统标准——“物质状态改变”。文章认为,专利法区分抽象思想与具体技术的传统标准并不像诸多学者所想象的那样否定计算机程序算法的客体属性。程序算法是运行独立于人脑的物理系统(计算机)的具体方法步骤,并非抽象的思维规则。程序算法被执行后会导致传统专利法意义上的“物质状态改变”。因此,程序算法符合前述传统标准,可顺利通过客体审查。沿着这一思路对专利法的传统理论进行整理,能够最大限度地尊重专利法传统,同时又及时地消除了技术进步对客体审查理论的挑战。
