Interactive transport of multi-view videos for 3DTV applications

The authors propose a novel method for transporting multi-view videos that aims to keep the bandwidth requirements on both end-users and servers as low as possible. The method is based on application layer multicast, where each end point receives only a selected number of views required for rendering video from its current viewpoint at any given time. The set of selected videos changes in real time as the user‘s viewpoint changes because of head or eye movements. Techniques for reducing the black-outs during fast viewpoint changes were investigated. The performance of the approach was studied through network experiments.

Defining standards for rankings: An investigation of global university rankings according to the Berlin Principles

The role of universities as the engines of knowledge-based economies drives global internationalisation of higher education. This contributes to a competitive environment where higher education rankings indicate market value. Even though rankings are influential and are used a lot, ranking systems have been heavily critiqued. One of the problems is that there are few if any external checks on how rankings are created. The purpose of the study on which this article reports was to evaluate ranking systems. Within the scope of the study, we have sought to reveal to what extent current ranking systems comply with the Berlin Principles—prepared to create certain rules for rankings, and to ensure that rankings represent quality. A document analysis of publicly available documents online was carried out together with a review of printed and electronic publications on ranking systems. An evaluation form was prepared and used in this study for field experts to fill in. Findings show that ranking systems comply with the Berlin Principles in terms of methodology, transparency, and acceptability at a level that ranges from moderate to low. Overall, rankings do not consider differences in higher education and are not transparent about the processes by which rankings are developed. Rankings should for this reason be interpreted carefully and methodological weaknesses of rankings that can lead to false inferences should be recognised.

A factor analysis of reading attitudes along with measures of reading achievement and scholastic aptitude

The construct validity of the Survey of Reading Attitudes was investigated through a principal-factor analysis of the 88 items comprising the scale, along with measures of scholastic aptitude and reading skills (vocabulary and comprehension). The sample included 600 students selected so that 200 (100 boys and 100 girls) were obtained from each of the three intermediate grades. The Survey was administered orally to class-size groups, but copies of the booklet were also available to students. The factor structure showed a reading achievement factor along with the following eight dimensions of reading attitude: (1) expressed reading difficulty, (2) reading as direct reinforcement, (3) reading as enjoyment, (4) alternative learning modes, (5) silent vs. oral reading, (6) reading anxiety, (7) reading group, and (8) comics.
