Explorations into the drug users’ perspectives

Needle sharing among intravenous drug users: national and international perspectives.

Explorations into the Visualization of Policy Networks

Visualization is an important aspect of both exploration and communication of categorical as well as relational data. Graphical displays of policy networks are particularly attractive, since they enable authors to display in a compact way the relevant actors in a network, how they are related to each other, and what the overall structure looks like. Sociograms were early companions of social ne...

Further explorations into ternary complementary pairs

In [R. Craigen, C. Koukouvinos, A theory of ternary complementary pairs, J. Combin. Theory Ser. A 96 (2001) 358–375], we proposed a systematic approach to the theory of ternary complementary pairs (TCPs) and showed how all pairs known then could be constructed using a single elementary product, the natural equivalence relations, and a handful of pairs which we called primitive. We also introduc...

Preliminary Explorations into Just - in - Time Teaching

Accepting that learning is dialogic necessitates the development of teaching and learning activities that support a learning-conversation. Further, Blended Learning requires learning technologies to support the conventional teaching settings by constructing activities that enhance, rather than simply replace, the conventional teaching settings. Just-in-Time Teaching is one such strategy that ac...

Explorations into Unsupervised Corpus Quality Assessment

Corpora, large bodies of text, are of great importance to the field of Natural Language Processing. They are for instance used to train systems on specific tasks through machine learning. When a system is trained on a corpus of low quality, it will not provide reliable results. We search for a metric of corpus quality by comparing the vocabulary growth data, the Zipf slopes and the Pareto expon...
