The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means.  相似文献

This paper examines the category of "Woman" within the metastructure of a system of knowledge organization. We trace the subject scheme used to list books about women in a standard bibliographic guide over the first three-quarters of the twentieth century.Building on the feminist critique of subject representation, our analysis documents how the category was continually constructed over time, providing evidence of multiplication, isolation, and confusion in the process. The outcome is a framework that fails to capture the complex nature of knowledge about women and conceals relationships to the larger body of knowledge. The case of this legacy system exemplifies problems associated with representing the complexity and integration of knowledge and provides a basis for considering the potential residual impacts of current information organization and navigation systems.  相似文献

Contrary to the "retro" image often awarded them, and despite their continuing enthusiasm and responsibility for the organization of printed materials, librarians are upbeat about the prospects of an information society driven primarily by electronic technologies, but in which libraries can play an important part. Public librarians detect a natural correlation between the historic democratic mission of their institution and the increased accessibility made possible by digitalized sources. The library community's acceptance of the information society idea as a "given" social phenomenon supports discourses that play down historical continuities and herald the dawn of a new age. Such discourses ignore or reject historical evidence that points to the existence of past information societies, revolutions, and infrastructures defined, in part, by the operation of indirect surveillance, constituted by the bureaucratic information systems of modernity. Victorian Britain serves as a good example of an early information society, to which public libraries, themselves micro-information societies, contributed significantly. The role played by public librarians in the Victorian information society, illustrated in this article by evidence drawn from the contemporary library press, is seen in their preoccupation with the surveillance and ordering of knowledge; their adoption for library operations of the businesslike, bureaucratic procedures described recently by business historians; and their panoptic tracking of users and their activities.  相似文献

本研究选取Web of Science数据库,收集中国和德国发表的海洋学论文,将论文分为国际合著组与非国际合著组,利用文献计量学的方法,借助EXCEL、SPSS和UCINET软件,比较两国各年的发文量、论文的篇均作者和篇均参考文献数、收录期刊的影响因子、论文的被引频次以及合著国家。研究结果显示,中国海洋学领域的国际合著起步晚于德国,但发展迅速,近年来中国海洋学国际合著的论文量已超过德国;同时中国海洋学国际合著论文的质量和学术影响力都弱于德国,并且中国海洋学论文合著国家的范围也小于德国海洋学的合著国家。  相似文献

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction.  相似文献

在文献回顾的基础上构建城镇化进程中产业、空间与人口的交互发展对能源消费的融合传导机制, 并基于向量形式的Kaya拓展模型与“多项连乘和加总”的LMDI改进形式,对中国1998—2015年间的能耗总量变化进行因素分解。研究显示:城镇化对生产端能耗的拉动效应远大于生活端;传统能源驱动型产业的转型升级 与技术进步缓解了能源压力;近些年除消费支出以外的其他经济单元,因粗放型“三高”发展模式的改善,较居民 消费具有能耗比较优势;居民消费效应仍是间接能耗提升的主导因素,城乡居民消费行为趋同对生活能耗波动的正向贡献日趋增强,并随着人口规模的扩张成为能源可持续发展的掣肘;摊大饼式空间低密度蔓延加剧了能源 消费,仅人口集聚的规模效应对生活能耗波动具有负向贡献。进一步指出在新型城镇化能源约束强化的情境下,虽然产业层面的结构调整与技术进步对能耗的削减效应仍存在,但更应关注人口层面的居民消费方式及用能习 惯的改良,释放空间层面的资源配置对降低能耗的新动能,努力实现共享经济以缓解能耗压力,并据此提出几点 建议。  相似文献

The Principles of Fair Information Practice are almost three decades old and need to be broadened to take account of new technologies for collecting personal information such as drug testing, video cameras, electronic location monitoring, and the Internet. I argue that the ethics of a surveillance activity must be judged according to the means, the context and conditions of data collection, and the uses/goals, and suggest 29 questions related to this. The more one can answer these questions in a way that affirms the underlying principle (or a condition supportive of it), the more ethical the use of a tactic is likely to be. Four conditions are identified that, when breached, are likely to violate an individual's reasonable expectation of privacy. Respect for the dignity of the person is a central factor and emphasis is put on the avoidance of harm, validity, trust, notice, and permission when crossing personal borders.  相似文献

The development of vaccines to prevent infectious diseases has been one of the most important contributions of biomedical sciences. Increasing understanding in biochemistry, molecular biology, molecular genetics and related fields have provided an opportunity for the development of new generation vaccines that are based on rational design approaches. This is possible because of proper understanding of the microbial-genetics, biochemistry, host-pathogen interaction and recent developments in molecular immunology. Another important improvement made in the quality of vaccine production is the incorporation of immunomodulators or adjuvants with modified delivery vehicles viz liposomes, Iscoms and microspheres apart from alum being used as a gold standard. This article reviews the art of vaccination from Jenner period to present day context highlighting all the developments made at each stage of the vaccine development. Various criteria have been discussed regarding the selection of epitopes that expand B & T cells, its linkage with other accessory cells of the immune system, means to overcome MHC linked immune unresponsiveness, enhanced antigen processing and presentations that specially induce either helper or cytotoxic or mucosal immune responses were critically discussed.  相似文献
