The effect of schooling on nutritional knowledge, attitudes and nutritional outcomes in Ethiopia was investigated. Data were obtained in late 1989 in Debre Birhan in Shoa province from three groups: 267 mothers, 114 clinic users and six primary schools with…

Stemming from the dialectical concepts of critical epistemology developed by feminism and Critical Theory (specifically, the Frankfurt School), this thesis attempts to articulate the political dimension of knowledge and to demonstrate how this dimension is incorporated into the liberatory pedagogical…

This thesis is about how medical knowledge is constructed by staff for patients and their families in a Japanese 'comprehensive care' facility for the treatment of epilepsy (the JEC). The thesis sets out to explain the possible reasons for differences…

A survey was undertaken to assess the knowledge, attitudes and practices, with respect to malaria, of 300 women from six randomly selected rural communities in Central Ethiopia from December 1991 to February 1992. Eighty-five per cent were able to recognize…

Concept mapping in college-level physics was investigated. The study was carried out in three parts. First, an attempt was made to validate concept mapping as a method of evaluating student learning at the junior college level (ages 16-21). Several measures…

A methodology was developed in this study for identifying the cognitive, pedagogical, and computational characteristics of computer-based learning environments. The characterization of the cognitive and pedagogical features was achieved by decomposing the learning environments into episodes which were composed of…

Additive and multiplicative statistical models in epidemiology invoke different assumptions regarding exposure-outcome relationships. While either may seem to provide an adequate fit in small data sets, a comparative parameter based on the correct set of assumptions will be more stable…

The development of language in physically handicapped individuals using augmentative and alternative communication (AAC) systems has not been described. Therefore our understanding of the role of AAC language encoding limitations in the development of syntax is limited. This study examined…

A design for a unified model based on the hypermedia paradigm is proposed as a means to a better synergism of the functionalities of different knowledge manipulation tools. A survey of past and present hypermdia systems has been achieved, and…

This thesis explores the use of randomized, performance-based search strategies to improve the generalization of an automatic speech recognition system based on hidden Markov models. We apply simulated annealing and random search to several components of the system, including phoneme…
