This historical review traces the con­ cept of work throughout the develop­ ment of occupational therapy. Para­ digm shifting is used as a framework for describing the conceptual defini­ tions and therapeutic uses of work in four developmental stages. T he concept of work is funda­ mental to our profession; the terms occupation and therapy con­ note the strong relationship be­ tween healing and...

T he field of neurotrophin biology has made great advances in recent years to include a greater understanding of signaling pathways and broader understanding of the diverse biological roles of these molecules. This review will focus primarily on the nerve growth factor family of neurotrophins and how recent descriptions of the molecular function of both the ligands and the receptors have helped...

number of new drugs which have appeared during the last three years have been included and the author has been very wise in exercising a judicious caution in their selection. The sulphanilamide group of drugs which, is still in an experimental stage has received adequate attention. The book has been well written and brings out with great clarity the really important actions and therapeutic uses...

ION IN MATHEMATICS What does it mean to say that mathematics is “abstract”? Mathematics is a self-contained system separated from the physical and social world:  Mathematics uses everyday words, but their meaning is defined precisely in relation to other mathematical terms and not by their everyday meaning. Even the syntax of mathematical argument is different from the syntax of everyday lang...

This paper explores the use of statistical machine translation (SMT) methods for tactical natural language generation. We present results on using phrase-based SMT for learning to map meaning representations to natural language. Improved results are obtained by inverting a semantic parser that uses SMT methods to map sentences into meaning representations. Finally, we show that hybridizing thes...

The lexicon has long been assumed to be the source of all conceptual content expressed by sentences. Syntactic structures have correspondingly been seen only as providing instructions for the assembly of the concepts expressed by words. Under this view, sentences have meaning, but the syntactic structures which sentences instantiate do not. This paper challenges this view: it uses the phenomeno...

We present a computer-based model of acquisition of word meaning from context. The model uses semantic role assignments to search through a hierarchy of conceptual information for an appropriate meaning for an unknown word. The implementation of this approach has led to many surprising similarities with work in modelling human language acquisition. We describe the learning task and the model, t...

This paper argues that multiple coordinations like tall, thin and happy are interpreted in a “flat” iterative process, but using “nested” recursive application of binary coordination operators in the compositional meaning derivation. Ample motivation for flat interpretation is shown by contrasting such coordinations with nested, syntactically ambiguous, coordinate structures like tall and thin ...
