ABSTRACT

This forum brings together food, (in)security, and communication. The authors participating in this forum center communication as both process and tool for understanding, mitigating, and making meaning of food (in)security. The nine authors together discuss the role of communication in food (in)security, the central challenges for scholars and practitioners working on food (in)security, and the creative possibilities and impacts influencing the future of food (in)security. The forum produces a call for applied scholars to re-imagine communication frameworks in order to make meaningful differences in their communities.  相似文献

Anonymous personalization in collaborative web search   总被引:2,自引:0,他引:2  
We present an innovative approach to Web search, called collaborative search, that seeks to cope with the type of vague queries that are commonplace in Web search. We do this by leveraging the search behaviour of previous searchers to personalize future result-lists according to the implied preferences of a community of like-minded individuals. This technique is implemented in the I-SPY meta-search engine and we present the results of a live-user trial which indicates that I-SPY can offer improved search performance when compared to a benchmark search engine, across a variety of performance metrics. In addition, I-SPY achieves its level of personalization while preserving the anonymity of individual users, and we argue that this offers unique privacy benefits compared to alternative approaches to personalization.  相似文献

ABSTRACT

Social media is a powerful tool for building an online presence, but it asks a lot. While it affords plentiful opportunities for professional development and networking, building a professional brand in an online space is not without its drawbacks and risks. By working from a set of actionable principles and benchmarks, users can minimize frustrations and setbacks to build a useful professional presence, all while imbuing the web with the tenets of good information stewardship.  相似文献

The authors assessed the influences of several risk factors—self‐esteem, history of unwanted sexual contact (USC), depression, and sorority membership—on eating‐related and weight‐related attitudes and behaviors. Findings provide support for the roles of self‐esteem, depression, and USC on restricting attitudes. According to the authors' model, these independent variables predicted restricting attitudes that then predicted restricting behaviors. Implications for preventive interventions and the study's limitations are discussed.  相似文献

Software engineering tasks, during both development and maintenance, typically involve teamwork using computers. Team members rarely work on isolated computers. An underlying assumption of our research is that software engineering teams will work more effectively if adequately supported by network-based groupware technology. Experience of working with groupware and evaluating groupware systems will also give software engineering students a direct appreciation of the requirements of engineering such systems.  相似文献
