数字图书馆异构数据库的现状及解决方法 总被引:3,自引:0,他引:3
由于数字图书馆数据库的发展过程中存在异构数据的现象,给读者查询带来极大的不便,因而需要对异构数据进行整合与集成,使其具有集成性、完整性、一致性和访问安全性等,以便于读者查询访问,实现图书馆信息资源的真正共享。目前,利用VC++的ODBC技术,已经能够很好地解决数据库管理系统本身异构的多源异构数据库的共享问题。 相似文献

Analyzing 219 blog posts from 52 self-employed women lifestyle bloggers in North America, this study shows how these digital professionals navigate tensions and communicatively constitute work flexibility. In their narratives, women bloggers employed tension management approaches such as reframing, continual connections, and reflective practice in response to tensions in enacting temporal–spatial, identity, and financial flexibility. Specifically, women followed oxymoronic constructions – disciplined freedom, branded authenticity, and dependable independence – to embrace and transform competing poles of fluidity?structure, authenticity?marketability, and independence?interconnection. Expanding work–life research to the self-employed digital labor context, this study responds to recent calls to uncover more-than tension management strategies in empirical settings and contributes to a tension-centered, contextual, and processual analysis of workplace flexibility construction. 相似文献

The digital divide refers to the differential patterns of Internet access adoption and usage across different segments of populations. The digital divide has been linked to demographic variables such as age and gender, and socioeconomic characteristics such as education and income. Using a nationally representative Canadian survey (N = 27,223) conducted in 2013, this paper investigates whether religiosity has an independent effect on the digital divide, accounting for the previously validated predictors of Internet use. Religiosity is found to negatively associate with Internet access and activity, controlling for a large set of characteristics such as age, ethnicity, education, and income. The religiosity-related gaps in the usage patterns appear to indicate lifestyle differences for those without any tie with religion compared with the individuals of average religiosity. For the very religious, the gaps indicate that they utilize the Internet for social networking less than others. Various implications are discussed. 相似文献

Current publishing practices in academia tend to result in datasets that are difficult to discover. This is because datasets are not well-integrated across academic domains and they are often not linked to the documents that reference them. For these reasons, discovering datasets across domains can be challenging; for example, discovering archeological observations and biological specimens using the same search is not widely supported, even if both datasets share a similar spatial extent, like Mesoamerica. It is also challenging to retrieve relevant documents that reference datasets; for example, retrieving a series of field reports that reference archeological observations is typically not supported. Our work develops an extensible method for: (1) geographically integrating collections across disciplinary repositories and (2) connecting datasets to related documents. We describe a collection of spatially-referenced researcher datasets, capturing their metadata elements and encoding them as linked open data. We then leverage existing library services to formalize links from datasets to documents. The system described in this work has been deployed, resulting in an experimental open data site for the UCSB campus. Results indicate that this system can be scaled-up with support from an institutional repository in the near future. 相似文献

Industry advocates argue that by tailoring services and commercial solicitations to match media users’ personal interests, data-driven marketing benefits both consumers and businesses. This article shows, however, that advertisers and marketers who are taking up ideas and techniques from behavioral economics tell their clients a very different story about the aims and use of digital marketing and consumer surveillance. Listening in on this discourse demonstrates that some digital marketers conceptualize their own practices as forms of social control, appropriating concepts from behavioral economics to identify consumers’ cognitive and affective biases and target their vulnerabilities. Behavioral economics recognizes that economic decisions are not simply dictated by rational self-interest; rather, such choices depend on cognitive heuristics and habits, and can be manipulated through the design of “choice architecture.” This article discusses implications of the behavioral turn in data-driven marketing for critical advertising scholars, public advocates, and regulators. 相似文献
