The aim of this study was to develop a Matrix of Analysis for Sports Tasks (MAST), regardless of the sports activity, based on practice classification and task analysis. Being this a qualitative research our main question was: in assessing sports' structure is it possible to make the characterization of any discipline through context and individuals' behaviours? The sample was within a surf dis...

There is a serious problem with one of the assumptions made in the security proof of the SURF scheme. This problem turns out to be easy in the regime of parameters needed for the SURF scheme to work. We give afterwards the old version of the paper for the reader’s convenience.

Automatic image annotation is a challenging field with a far reaching effect. As the world moves towards becoming more and more dependent on digital technologies every day, use of machine to automatically annotate images can be proved as demanding in many fields of image processing. Automatic Image Annotation reduces the gap between low level image features and high level image semantics. Utili...

Short-lived radium isotopes (223Ra and 224Ra) are used to investigate the potential association between groundwater discharge and microbial pollution at Huntington Beach, CA. We establish the tidally driven exchange of groundwater from the surficial beach aquifer across the beach face. Groundwater is found to be a source of nutrients (silica, inorganic nitrogen, and orthophosphate) to the surf ...

13 SURF is also currently based on a single user, stand-alone model, resulting in ineecient use of network resources. Articles may be retrieved from the NNTP server multiple times, once for each user. We are currently developing a version of SURF based on a client-server architecture which would allow us to optimize access to the news server by retrieving each article only once for multiple use...

Pneumomediastinum is an uncommon complication of sporting activity. The case of a young asthmatic surf lifesaver is reported in which several factors are thought to have been involved in the aetiology of his condition. Treatment was expectant and a full recovery was made over a short period. This is the first reported case of pneumomediastinum occurring following training for a surf belt race.

BACKGROUND New health information technology (HIT) increasingly plays a role in health care as technology becomes cheaper and more widespread. However, there is a danger that those who do not use or have access to technology will not benefit from HIT innovations, thus creating a "digital divide". AIMS To assess the extent to which mental health service users have access to, skills in using an...
