E-learning quickly became a crucial tool for universities and other higher education institutions during the global COVID-19 pandemic. The field of sport physical (PE) was no exception. However, though there is considerable growth in digital technologies or education, we have very little evidence about use outcomes these technologies. Thus, this study aims to document how e-learning pedagogical...

This deliverable contains two major pieces of work specifically associated with Task 6.4 within Workpackage 6. (1) A concept of traversable mixed reality boundary is articulated and innovative designs for devices and displays are presented so as to support participants as they cross between ‘realities’. (2) Techniques for gesturally engaging with interaction surfaces are described as being of c...

In our global world, the increasing complexity of social relations and transport infrastructures are key factors in the spread of epidemics. In recent years, the increasing availability of computer power has enabled both to obtain reliable data allowing one to quantify the complexity of the networks on which epidemics may propagate and to envision computational tools able to tackle the analysis...

First, the artifacts on display are supposed to be real. For example, a real amphora is displayed and not its photograph or some other facsimile. There are many disadvantages to this practice: Some artifacts are too large, or may be incomplete, making their display difficult; expensive measures have to be taken to assure security for the artifacts; and the displays need environmental conditions...

The Impact Factor was originally devised as an index of the quality of scientific journals and has since obtained mythical proportions. Authors select journals to which they submit their work on the basis of that journal's Impact Factor. Medical school deans and administrators have adopted the Impact Factor as a means of judging the quality of the academic efforts of individual faculty, as well...

E lectronic voting has been around since the 1970s, but until the US’s 2000 Gore-Bush presidential election, it was largely out of the public eye. After the Florida punched-card debacle, it became clear that our election infrastructure needed renovation. The Help America Vote Act of 2002 mandated a solution of sorts, making US$3 billion available to states to move away from their long-lived, we...

The goal of contemporary research in pemphigus vulgaris and pemphigus foliaceus is to achieve and maintain clinical remission without corticosteroids. Recent advances of knowledge on pemphigus autoimmunity scrutinize old dogmas, resolve controversies, and open novel perspectives for treatment. Elucidation of intimate mechanisms of keratinocyte detachment and death in pemphigus has challenged th...

Over the last decade, the increases in capacity promised by multiantenna communication techniques have spurred many information-theoretic analyses. Furthermore, information theory has been used as a design tool to optimize the signals fed to the transmit array and to motivate signal processing strategies at the receiver. In this chapter, we catalog a number of misconceptions that have arisen in...
