基于最大收益的无线虚拟网络重映射算法

针对无线环境的动态性及虚拟网络请求到达与离开的随机性,使得物理网络负载分布不均衡,导致后续请求的接受率降低的问题,提出一种无线网络虚拟化中的两阶段重映射算法（two stages reconfiguration scheme for wireless network virtualization,TR-WNV）。该算法通过第1个阶段选出合适的虚拟网络进行重映射,接着在第2个阶段按照优先级对已选出的虚拟网络进行重映射,并根据离散度来判断每次映射效果。最后,通过仿真对算法进行验证,结果表明该算法在保证虚拟网络请求收益最大化同时,有效提高了虚拟网络请求接受率,实现整个底层网络的负载分布均衡。     

网络游戏虚拟物品的法律保护

目前,我国法律对网络游戏虚拟物品未作出明确的权利定性。从本质上看,虚拟物品属于法律规定的财产范畴,符合传统民法上"物"的特性,应被定性为物权的客体,可以通过直接立法和间接立法两种方式来实现对虚拟物品的保护。     

Women Auto Know: Automotive knowledge,auto activism,and women's online car advice

Although women influence nearly 85 percent of new car sales, their experience at automotive dealerships differs significantly from that of men. Not only are women subject to sexist and patronizing behavior from automotive personnel, but they also often wind up paying considerably more for a vehicle than a male customer. In the past two decades, the Internet has evolved as a significant source of automotive information and advice. While the majority of car advice websites offer guidance to the general public, a handful address the automotive concerns of the female driver. These sites are significant not only for the information they make accessible to female visitors, but for what women gain—as drivers, consumers, and political actors—by reading them. This paper examines four popular websites that cater specifically to the woman driver. Calling upon feminist epistemologies, it demonstrates how such online locations empower women to become more informed drivers and consumers through the accumulation and distribution of women's automotive knowledge. Not only does this automotive knowledge aid women as negotiators, but it also provides them with the tools necessary to radically transform the hostile auto dealership culture, ultimately benefiting all in the market for an automobile.     

虚拟机软件在中职网络教学和实训中的应用

随着全国中等职业学校计算机技能大赛的举办,中职学校网络实训环境发生了改变,虚拟机软件在网络教学中得到了广泛的应用.通过虚拟机软件可以建立虚拟化的实训环境,模拟真实的计算机系统.使用虚拟机软件既可以克服教学资源和设备不足的困难,又可以解决实训时长不足,完成真实环境难以实现的实训任务,保证网络教学和实训的顺利进行.     

农村社会生态理性的社会学研究

本文从理性视角构筑认识论框架,在此框架内对环境价值作出评估。在肯定理性多样化并存的前提下,把两个最具争议的理性——经济理性与生态理性并列齐观,以阐明二者在环境问题上的分歧,并从中揭示出中心价值对边陲价值的侵犯,并以政治形式将其合法化、正当化的过程。如何实现经济理性与生态理性的和解,宏观层面需要工业文明向生态文明的转变,微观层面需要从＂以人为中心＂的价值观向＂人与环境和谐共处＂的价值观转向,在这一转向过程中经济理性与生态理性相平衡的价值观教育是很有必要的。     

Mapping the social geographies of autism – online and off-line narratives of neuro-shared and separate spaces

This paper draws together empirical work that has been produced by the authors in two different autistic spaces: the Swedish magazine Empowerment produced by and aimed at adults with autism, and English-speaking autistic communities online. While the two points of data collection are quite different, there are important points of commonality that enable us to explore central issues concerning autistic and neurotypical space and the meanings assigned to these in different contexts. The paper aims to introduce the notion of social geographies of autism, based on talks among adults with autism and a social movement to promote autistic identities, giving examples from our previous work that has spanned both online and off-line spaces. Key issues discussed in the paper include a focus on autistic political platforms and the carving out of both social and political spaces for people with autism. In doing so, neuro-separate and neuro-shared spaces must be negotiated.     

How to make e-Procurement viable for SME suppliers

Due to their common role as suppliers, small and medium-sized enterprises (SMEs) are especially challenged by today's turbulent business conditions. In order to meet this challenge, short-term WWW-based enterprise cooperations are regarded as an appropriate way to enhance the competitive strength of SMEs. Hence, the Institute of Machine Tools and Industrial Management (IWB) operates three so-called competence networks for engineering (www.engineering-net.de), rapid prototyping (www.rp-net.de) and manufacturing (www.produktionsnetz.de) services. For the purpose of an applied research project, more than 80 participating SME suppliers have been included in these specialized virtual markets, which are based on the core competencies of the cooperating SMEs. Additionally, the platform (www.virtueller-markt.de) enables customers to configure their specific supply chains via the above-mentioned competence networks. The presented paper depicts how to establish and operate these competence networks as well as how to configure supply chains via these virtual markets.     

Seasonal work and aboriginal employment in two rural areas of New South Wales, 1921–78

This paper has several areas of focus. It chronicles the history of Aboriginal employment in Australia in two contrasting areas; it identifies the characteristics of that employment and traces the nature of its change over time; it outlines the attitude of Aborigines towards their work, and the impact of that work on Aboriginal society; it also considers the attitudes of white Australians towards Aborigines and their employment. Finally, it draws some conclusions concerning the responses of the Aborigines to pressures put on them by the economy and society of the white man.

数字化时代与“艺术终结”论（笔谈）——艺术的黄昏与黎明

数字化时代,为文学艺术的发展开辟了广阔的发展空间,创造了前所未有的新的条件.它不仅要求艺术家做一个现代人,换脑、换笔,更新知识结构,而且要求艺术家在继承人类优秀文艺传统的基础上,更加自觉地掌握现代艺术的特点和规律,创造出无愧于新的时代的艺术珍品.艺术的终结,恰恰是艺术新生的起点,艺术的黄昏则是艺术的黎明的前夜.
