This thesis will explore the design and optimization of a peer-to-peer network application as a solution to complex content management problems. Currently, most content management systems are expensive, cumbersome and inflexible custom solutions that require knowledge workers to change their…

In this work we present an approach to model an action-oriented system controlled by BDI agents using a defeasible argumentation formalism to represent its knowledge. Here, our main concern will be modelling the software agents that drive the physical robots.

Knowledge of how groups of people interact is important in many disciplines, e.g. organizational behavior, social network analysis, knowledge management and ubiquitous computing. Existing studies of social network interactions have either been restricted to online communities, where unambiguous measurements about…

This study analyse the influence of Knowledge of Results (KR) with different accuracy levels on the learning rate of a throwing skill of spatial non-vision accuracy, during the acquisition stage. We assessed the number of successful events, the distance from…

Understanding the biological signals encoded in a genome is a key challenge of computational biology. These signals are encoded in the four-nucleotide alphabet of DNA and are responsible for all molecular processes in the cell. In particular, the genome contains…

This thesis explores how doctors and nurses use documents to share their knowledge within and across healthcare settings. In addressing this question I draw on a 15-month, multi-sited ethnographic study in several pediatric health care settings, following patients from primary…

Diabetes mellitus is a syndrome which affects more and more people in all countries over the world. In Mexico, it is commonly treated with herbal extracts. Such treatment may be of considerable benefit especially during the early stages of the…

Discussion of the natural sciences had a foundational role in the development of the sociology of race and racism, underpinning the claim that races should, if at all, be studied as social rather than natural phenomena. Whatever its strengths, the…

There is a significant world-wide apprehension concerning perceived deficiencies in university students’ performance and a resulting decrease of knowledge level and competency development. This paper analyses the benefits of using a portfolio as a means of evaluating student progress and…

Reinforcement of learning in practice may help students learn bioscience but is contingent on adequate support from staff nurses. A 'snapshot' of the situation in practice was obtained (2006/7), with context from lecturers. In Stage 1, surgical care nurses were…
