Language Assessment in Practice by Lyle Bachman and Adrian Palmer is a defining text within the field of language assessment. With an expected readership of students, language teachers with varying experience, applied linguists, professional language testers, materials developers and textbook writers, Language Assessment in Practice is ambitious at its core. Nonetheless, the authors‘ logical ap...

Semantic Similarity relates to computing the similarity between concepts of ontology. There exist four approaches to calculate the semantic similarity. The first approach is based on path length. Under this approach we studied and compared some of the measures on a bench mark dataset. Among the compared measures Wu & Palmer measure has the advantage of being simple to implement and has better p...

A number of experimental techniques have been used to study two of the equilibria which control the speciation of solutions of molecular iodine in water. These are the tri-iodide formation reaction; 12 + 1= 13and the iodate formation reaction: 312 + 3H20 = 103+ 51+ 6H+. The eqiulibria were studied at temperatures up to the region 150 to 200.C. The 13formation reaction was studied by a vapour eq...

Keratosis, one of the earliest skin manifestations of arsenicosis, can be treated by either oral or topical formulation of drug. In this study we examined the effectiveness and tolerance of propylene glycol for the treatment of arsenical palmer keratosis. Sixty patients of arsenicosis with palmer keratoses were randomly divided into three groups and different concentrations (15, 30 and 45%) of ...

In the contextual complexity of modern, computerised systems, the current system state can come as an unpleasant shock to even an experienced user. In this paper, we show that errors, which occur within such complexity, cannot easily be described in terms of individual tasks and their component actions. We use this starting point to examine the dominant thinking in this field (Palmer, 1995, Pal...
