论信息产品责任的法律调整 总被引:1,自引:0,他引:1
信息服务广泛应用于工农业生产、科学研究、商业流通等各个领域。在信息服务过程中,由信息产品缺陷致害所引发的法律责任问题大量涌现。必须及时对信息产品责任这一新问题进行法律思考,必须用法律的手段规范信息服务、促进信息产品交易、保护消费者合法权益。 相似文献

1958年颁布的《国防教育法》对认识二战后美国的教育变革有重要意义。但长期以来研究者都视其为对"苏联卫星事件"的回应,是冷战时期国防政策的重要内容。笔者通过对文献的重新发掘与分析,指出两者之间不存在必然联系,这场教育改革不是"刺激-反应"模式的产物;此外,该法案立法过程中的焦点问题是对联邦政府干预教育权限的再讨论;法案通过后,在宣誓政治忠诚和学术自由问题上也受到广泛批评。国家安全不能概括法案的全部,至于联邦政府如何干预教育,以法案为代表的每一次讨论本身就是答案。 相似文献

Product cycles have long been used in software development, but libraries can also benefit from a structured product life cycle to help manage technology development and acquisition. This article outlines a proposed product cycle for library technology management with information on implementing each step of the cycle. It will also include information for librarians assessing the success of structured technology management. 相似文献

Librarians in Sweden are facing huge challenges in meeting the demands of their organisations and users. This article looks at four key areas: coping with open science/open access initiatives; increasing demands from researchers for support doing systematic reviews; understanding user experiences in Swedish health science libraries; and the consequences of expanding roles for recruitment and continuing professional development. With regard to changing roles, there is an increasing shift from the generalist towards the expert role. The authors raise the issue as to how to prepare those new to the profession to the changing environment of health science libraries. 相似文献

A number of voices have emerged in U.S. political discourse questioning the legitimacy of American exceptionalism, suggesting we are in a “post-American world.” Our research examines the effects that political messages that explicitly challenge American exceptionalism can have on U.S. public opinion. Drawing upon social identity theory, we find that explicit challenges to American exceptionalism significantly impact Americans’ views toward their own nation, their willingness to denigrate foreign publics, and their broader foreign policy preferences. 相似文献

Human anatomical specimen museums are commonly used by medical, nursing, and paramedical students. Through dissection and prosection, the specimens housed in these museums allow students to appreciate the complex relationships of organs and structures in more detail than textbooks could provide. However, it may be difficult for students, particularly novices, to identify the various parts of these anatomical structures without additional explanations from a docent or supplemental illustrations. Recently, augmented reality (AR) has been used in many museum exhibits to display virtual objects in videos captured from the real world. This technology can significantly enhance the learning experience. In this study, three AR-based support systems for tours in medical specimen museums were developed, and their usability and effectiveness for learning were examined. The first system was constructed using an AR marker. This system could display virtual label information for specimens by capturing AR markers using a tablet camera. Individual AR markers were required for all specimens, but their presence in and on the prosected specimens could also be obtrusive. The second system was developed to set the specimen image itself as an image marker, as most specimens were displayed in cross section. Visitors could then obtain the label information presented by AR without any markers intruding on the display or anatomical specimens. The third system was comprised of a head-mounted display combined with a natural click interface. The system could provide visitors with an environment for the natural manipulation of virtual objects with future scalability. 相似文献
