Internet presence and historically black colleges and universities: Protecting their images on the World Wide Web?

This study examines how historically black colleges and universities (HBCUs) use their home pages to present images of themselves. The home pages of 96 institutions were examined using content analysis. The findings suggest that HBCUs are not using their home pages to project a strong image. For example, less than 10% of these institutional home pages made mention of institutional rankings, and less than 20% made mention of students, athletics or faculty. The authors make suggestions for how HBCUs can better project institutional image with changes to home page content and design.

An alternative estimator for multiple characteristics in PPS sampling

The problem considered relates to large-scale sample surveys. A new estimator of population total for the characteristics that are poorly correlated with the selection probabilities has been developed for the PPSWR sampling scheme. The relative efficiency of the proposed estimator has been studied under a super-population model. A numerical investigation into the performance of the estimator has also been made.

WEB PAGES, AUTHORS AND AUDIENCES: The meaning of a mouse click

One popular framework for analysing web pages has been to think of them as identity performances on the part of the author. This framework opens up possibilities for analysis of the ways in which identity performances are composed. The personal web pages to which this perspective is most immediately applicable, are, however, now only a small proportion of the overall amount of information available on the World Wide Web. It would be possible, by extension, to analyse institutional web pages as performances of the institutional identity. It is the contention of this paper that to do so is to miss out on some important aspects of web page design: namely that the production of a web page involves understandings not only of the audience for the page but also of the capacities of the technology. In addition, web page production has to become a socially meaningful act for the individual web page developer and the institution concerned. It is, therefore, argued that the analysis of web pages can usefully learn from media studies and the sociology of technology in this respect. An interview-based study of the developers of web pages for the service departments of a UK university is described. The ideas of audience which the authors use are far from homogeneous: they include an institutional offline audience for the page, a pre-existing imagined audience, developers themselves as audience, and the technology of the browser as a stand-in audience. The audience and the capacities of the technology are developed in context through the practices of designers.     

基于滑动窗口的自适应网页预测模型

PPM模型广泛应用于Web预取技术,但大多数的PPM模型不具有自适应性,不能反映用户浏览模式的改变。通过对标准PPM模型的扩展,提出基于滑动窗口的自适应网页预测模型。该模型仅保留处于滑动窗口之内的最近访问序列,从而反映用户兴趣的变化,同时利用非压缩后缀树增量式添加新的用户请求和删除过时的浏览信息,以提高更新速度。实验表明,该模型能更准确地描述用户在Web上的浏览特征,在预取性能上明显地优于以往的模型。
