路翎是主体意识很强的作家,他强烈地感受到生命中无穷无尽的、无法摆脱的苦难,从而试图通过文学作品去展现这种悲苦。路翎思考的着力点并不是如何在现实中免去烦恼,摆脱苦难,而是抱定一种超越的信念和高贵的人生态度去抒写面对苦难的精神方式。路翎面对苦难的精神取向表现为三个层次:追问、寻觅、救赎。 相似文献

WWW以其多媒体的传输及良好的交互性而倍受青睐.但由于Web服务和网络固有的延迟,用户并没有得到与带宽相应的服务体验.为此文章提出了一种基于云端的智能Web预取技术,它能够加快用户浏览Web页面时获取页面的速度.该技术通过简化的WWW数据模型表示用户浏览器缓冲器中的数据,在云端利用数据挖掘技术挖掘类聚用户隐含的兴趣关联规则,并利用类聚用户的历史连接记录创建确定的影射关系模型,存放在云端兴趣关联知识库中,作为对用户行为进行预测的依据.在用户端,浏览器插件负责在用户带宽空闲时根据用户兴趣进行Web预取,从而对用户实现透明的高速浏览. 相似文献

Recent research has indicated the use of the Internet to meet sexual partners among men who have sex with men (MSM) is increasing. This medium also serves as a major source for social and sexual networking among MSM who live in more rural areas. In addition, data suggest the use of the Internet to initiate sexual relationships among this population may increase the risk of transmission of sexually transmitted infections, including HIV. The purpose of this study was to examine differences between self-reported HIV serostatus and requests for condomless bareback (BB) sex among a sample of Florida MSM (n = 483) using a popular Internet sexual networking site to meet sexual partners. Specifically, these variables were assessed in relation to population size among the site's seven geographic regions within the state. Findings indicated an overall statistically significant relationship among requests for BB sex and self-reported HIV serostatus. However, there was not a significant relationship among these variables and geographic region. Thus, although previous data have emphasized the importance of different HIV prevention strategies among rural versus urban MSM, there may not be major differences in HIV serostatus and requests for unsafe sexual practices among these men who use the Internet to meet sexual partners in comparison to MSM in more populated areas. 相似文献

This essay introduces the reader both to the varieties of representations of queers currently available on US Web servers and to the kinds of critical questions that scholars and activists can ask about such representations. As such, the author surveys, summarizes, and analyzes both pertinent Websites and scholarly writing about queer representation, identity, community, and social agency. Ultimately, the author concludes that analyzing queer self-representation on the Web is a significant scholarly undertaking in that it can help us understand better (1) how queers use, represent themselves, and are represented on the Web, and (2) what such representations might mean for our understanding of ourselves, our cultures, and our future both locally and globally. 相似文献
