It was hypothesized that children with physical disabilities would show a deficit in procedural and declarative knowledge of ball catching compared to age-matched non-disabled children. The first group of children consisted of sixteen children with physical disabilities, three girls and…

The high rate of sexually transmitted diseases and teen pregnancies among the Cree adolescents indicate that this population frequently engages in unprotected sexual activities. AIDS is a critical health problem worldwide and AIDS contamination within a Cree community could be…

If we are to understand how we can build machines capable of broad purpose learning and reasoning, we must first aim to build systems that can represent, acquire, and reason about the kinds of commonsense knowledge that we humans have…

This thesis describes two programs for generating tests for digital circuits that exploit several kinds of expert knowledge not used by previous approaches. First, many test generation problems can be solved efficiently using operation relations, a novel representation of circuit…

The main objective of the present work is to investigate the nature of the cognitive processes responsible for the problem-solving operations of novices, intermediates, and experts in a semantically rich and complex domain, i.e. electronics trouble shooting, in relation to…

The thesis examines aspects of the construction of methylmercury as an authoritative object of knowledge for Chisasibi, a Cree community on the James Bay coast in northern Quebec. I describe the evolution of a particular set of spheres of exchange…

TYPICAL is a package for describing and making automatic inferences about a broad class of SCHEME predicate functions. These functions, called types following popular usage, delineate classes of primitive SCHEME objects, composite data structures, and abstract descriptions. TYPICAL types are…

I present a novel design methodology for the synthesis of automatic controllers, together with a computational environment---the Control Engineer's Workbench---integrating a suite of programs that automatically analyze and design controllers for high-performance, global control of nonlinear systems. This work demonstrates…
