[目的/意义] 期刊从订阅模式转向开放获取模式有多种途径,其中"为开放而订阅(S2O)"是一种新兴模型,正越来越受到向开放获取过渡的传统出版商的认可与接纳。[方法/过程] 运用文献调研法与内容分析法,梳理S2O模型的背景、发展,比较9家出版商采用S2O模型的75种期刊的情况。[结果/结论] 指出S2O模型的潜在问题包含订阅机构的流失、图书馆/文献中心的财政预算审查障碍、订阅费用透明度较差;解决措施包括经费补充机制及提供S2O模型期刊的使用数据。从为出版商提供开放获取转换的新途径、有利于保障非营利性出版商的发展两个方面提出S2O开放获取模式,为我国开放获取的理论与实践带来重要启示。 相似文献

在分析P2 P技术个人数字图书馆及的基础上,提出了可以抑制“搭便车”行为的基于社会信誉度的激励机制。由于该机制是利用最大流方法计算个人数字图书馆的信誉值,因此个人数字图书馆要想获得自己所需的资源就必须通过共享资源来提高自己的信誉值。 相似文献

In today's global culture where the Internet has established itself as the main tool for communication and commerce, the capability to massively analyze and predict citizens' behavior has become a priority for governments in terms of collective intelligence and security. At the same time, in the context of novel possibilities that artificial intelligence (AI) brings to governments in terms of understanding and developing collective behavior analysis, important concerns related to citizens' privacy have emerged. In order to identify the main uses that governments make of AI and to define citizens' concerns about their privacy, in the present study, we undertook a systematic review of the literature, conducted in-depth interviews, and applied data-mining techniques. Based on our results, we classified and discussed the risks to citizens' privacy according to the types of AI strategies used by governments that may affect collective behavior and cause massive behavior modification. Our results revealed 11 uses of AI strategies used by the government to improve their interaction with citizens, organizations in cities, services provided by public institutions or the economy, among other areas. In relation to citizens' privacy when AI is used by governments, we identified 8 topics related to human behavior predictions, intelligence decision making, decision automation, digital surveillance, data privacy law and regulation, and the risk of behavior modification. The paper concludes with a discussion of the development of regulations focused on the ethical design of citizen data collection, where implications for governments are presented aimed at regulating security, ethics, and data privacy. Additionally, we propose a research agenda composed by 16 research questions to be investigated in further research. 相似文献
