Mary L. Gray 《Journal of Computer-Mediated Communication》2009,14(4):1162-1189
Drawing on a 19-month ethnographic study, this essay explores how rural young people weave digital-media-generated source materials into their identity work, particularly as they navigate the politics of visibility's master narrative event: "coming out." More so than in urban scenes where a critical mass of LGBTQ visibility is taken for granted, these stories resonate with the complex negotiation of visibility and family ties that consume rural young people's everyday lives. At the same time the amount rural youth absorb or rework these categories has everything to do with each person's capacity to enact and publicly assert them. This approach to studies of media effects calls for a deeply situated understanding of media engagements beyond reception of particular media texts. 相似文献

TVDI在冬小麦春季干旱监测中的应用 总被引:2,自引:0,他引:2
应用冬小麦春季生长期的NOAA/AVHRR资料,反演归一化植被指数(NDVI)、土壤调整植被指数(SAVI)和下垫面温度(Ts),分析了植被指数和下垫面温度空间特征,采用温度植被旱情指数(TVDI),研究了河北省2005年3~5月的冬小麦旱情状况。结果表明:基于SAVI的温度植被旱情指数与土壤表层相对湿度的相关性好于基于NDVI的温度植被旱情指数。通过与气象站土壤水分观测资料进行相关性分析,表明温度植被旱情指数与10 cm土壤相对湿度关系最好,20 cm次之,50 cm较差。因此,基于SAVI的温度植被旱情指数更适于监测冬小麦春季的旱情。 相似文献

ABSTRACT Each year Dacus Library teaches library use to over a thousand freshmen in introductory Writing classes. In the summer of 2000, two reference librarians undertook a revision of the basic methodology of teaching library use to freshmen. This change was necessitated by staff shortages, coupled with increasing enrollment. The resulting virtual tour, which was introduced in fall 2000, combined an existing audio-tape tour with one hour of classroom instruction. The university's mascot, an eagle, was used to lead the students on a tour of all three floors of Dacus Library, with explanations of each location pictured. In addition, the eagle was used to describe and explain the online catalog. The new virtual tour, while still a work in progress, is considered to be a success by students, library faculty and staff, and Writing instruction faculty. You can visit the Dacus Library tour at www.winthrop.edu/dacus/About/Tapetour/Exercises/assignment2.htm. 相似文献

话题关联识别用于判断新闻报道对流中每对中的两篇报道是否描述了同一个话题.为解决其中报道篇幅短小、稀疏问题严重及其内容存在漂移等问题,提出了一种动态信息扩充技术,用于改进报道表示模型.该技术用过去最新的话题相关报道来扩充当前报道,动态更新原有模型.此外,还研究了扩充信息的精化问题,通过有选择地加重一些重要特征的权重来减小扩充过程中噪音带来的影响.该方法在TDT4中的中文语料上进行了实验,结果表明动态信息扩充技术能够较大幅度地改进话题关联识别的性能,对多种特征采取的精化技术也对性能改进产生了较大影响. 相似文献

ABSTRACT In tough economic times, it is more important than ever to be mindful of common sense security practices. The security posture of your organization can be increased with simple to remember safety tips, inexpensive security technology solutions, and by making your employees aware of rising security threats and ways to mitigate these threats. Risk is inherent to business operations and you can not totally eliminate all types of risks; however, there are some fundamental practices that can be implemented in your organization that will dramatically increase the protection of your organization. 相似文献
