SUMMARY Recent research has documented the growing gap between those who have access to information technology and those who do not. Reviewing available literature regarding the lack of access to computers and technology by oppressed groups, this paper discusses problems inherent in ignoring this issue in social work education and practice. Finally, some of the promising interventions currently used to address problems of access are outlined and recommendations for social workers are highlighted. 相似文献

Many firms that sell digital copies of copyrighted materials online face a common dilemma: the use of digital rights management (DRM) to impede pirates can impose restrictions on legitimate use. We introduce a two‐period model in which the use of DRM in the first period affects the probability that a consumer finds a pirated copy in the second period; the threat of legal action reduces consumers’ consumption of pirated copies; and firms choose whether to sell, and at what prices, either strongly or weakly DRM‐protected products, or both. Furthermore, we incorporate the role of uncertainty concerning future levels of piracy. Using a two‐period model with uncertainty, we investigate a firm's optimal DRM strategies and present the optimal pricing strategy as well as product launch strategy under different market conditions. We find that one important characteristic of the optimal strategy is that it is optimal to maintain the same product line configuration strategy for both periods. We also characterize the conditions under which each strategy is optimal. 相似文献

ABSTRACTCyber-safety behaviors are important in preventing the loss of an individual's digital assets and ensuring the safety of important daily online activities. Individuals’ cyber-safety is also critical for national cybersecurity. The issue is highly relevant for Israel, a country that relies on the digital capabilities of its workers for its major technology industries and is also often a target of cyberwarfare and cybercrime attacks. The purpose of this study is to identify the determinants of cyber-safety behavior. We investigate the role of age, gender and education in the use of safety-related digital skills and antivirus software. Using a 2014 survey of a national sample of Internet users in Israel (N?=?1850), we found that age, gender, education and quality of access are associated with the level of users’ digital security skills. In addition, these skills and the frequency of conducting financial activities online are the main determinants of antivirus behaviors. Our results expand the understanding of cyber-safety by showing that social and digital disparities are reproduced in the use of measures to prevent online threats, putting the digitally disadvantaged at greater risk of becoming victims of online threats. 相似文献

As a contribution to the ongoing tradition of critically assessing documents for research, this paper aims to highlight materiality as a key factor in the co-shaping of knowledge derived from digital documents. The paper first builds upon prior debates in document studies with work from the fields of Science and Technology Studies, and Communication Studies, to establish the role of document materiality in the interpretative process. By first establishing digital documents’ material reality as electrical signal, the paper then discusses the interpretative role of software, in both the representation of that signal for human interpretation and the production of the document through software tools. Finally, the paper considers the implications for persistence and access to digital documents posed by their material reality and the private archival contexts in which they often reside. 相似文献

In 2010 the U.S. State Department funded an “Apps4Africa” contest to encourage development of socially conscious mobile applications for Africa. The initiative marked a significant departure from traditional public diplomacy efforts to expand diplomatic outreach beyond traditional government-to-government relationships. This case study analyses Apps4Africa to reveal its appropriateness as a model for future efforts and concludes Apps4Africa succeeded primarily because it responded to the changing dynamics of the 21st Century. 相似文献

对数字化技术的价值探析,需要有人文理性的意义维度,以廓清其与人类预设的文化命意和精神旨趣相协同的可能限度,即数字化技术方式背后的哲学局限与艺术美学悖论。前者表现为数字标准化对事物个性意义体认的限制,数字平面化对事物深度认知复杂性的限制和数字的知识化对意志自由的限制;后者则蕴含了数字虚拟与艺术真实、文学在线与文学性消散、个体中心与主体边缘、精神临场与身体缺席等方面的对立与统一。 相似文献

The Pacific Rim Library (PRL) is an initiative of the Pacific Rim Digital Library Association (PRDLA). The project began in 2006 using the OAI-PMH paradigm and now holds over 300,000 records harvested from OAI data provider libraries around the Pacific. PRL's goal is to enable the sharing of digital collections amongst PRDLA members and the world, but greater unexpected benefits have been discovered. Through mirroring their metadata, PRL increases the chance that their data will be discovered in Google and other general search engines. With its many disparate collections, PRL is not a repository for traditional information discovery and retrieval. Initially users will bounce from a Google hit to the PRL metadata record in Hong Kong and then begin an intensive search on the original site which hosts the full digital object, in Vancouver, Honolulu, Wuhan, Singapore, or other PRDLA member location. 相似文献
