Smallholder farmers’ access to credit in the Amathole District Municipality, Eastern Cape Province, South Africa

Provision of credit has being identified as an important instrument for improving the welfare of smallholder farmers directly and for enhancing productive capacity through financing investment by the farmers in their human and physical capital. This study investigated the individual and household characteristics that influence credit market access in Amathole District Municipality, Eastern Cape Province, South Africa, using a cross sectional data from smallholder farmers’ household survey. The aim is to provide a better understanding of the households’ level socio-economic characteristics, not only because they influence household’s demand for credit but also due to the fact that potential lenders are most likely to base their assessment of borrowers’ creditworthiness on such characteristics. The results of the logistic regression suggest that credit market access was significantly influenced by variables such as gender, education, households’ income, value of assets, savings, dependency ratio, repayment capacity and social capital. Implications for rural credit delivery are discussed.

The Architect's Collaborator: Toward Intelligent Tools for Conceptual Design

In early stages of architectural design, as in other design domains, the language used is often very abstract. In architectural design, for example, architects and their clients use experiential terms such as "private" or "open" to describe spaces. If we are to build programs that can help designers during this early-stage design, we must give those programs the capability to deal with concepts on the level of such abstractions. The work reported in this thesis sought to do that, focusing on two key questions: How are abstract terms such as "private" and "open" translated into physical form? How might one build a tool to assist designers with this process? The Architect's Collaborator (TAC) was built to explore these issues. It is a design assistant that supports iterative design refinement, and that represents and reasons about how experiential qualities are manifested in physical form. Given a starting design and a set of design goals, TAC explores the space of possible designs in search of solutions that satisfy the goals. It employs a strategy we've called dependency-directed redesign: it evaluates a design with respect to a set of goals, then uses an explanation of the evaluation to guide proposal and refinement of repair suggestions; it then carries out the repair suggestions to create new designs. A series of experiments was run to study TAC's behavior. Issues of control structure, goal set size, goal order, and modification operator capabilities were explored. In addition, TAC's use as a design assistant was studied in an experiment using a house in the process of being redesigned. TAC's use as an analysis tool was studied in an experiment using Frank Lloyd Wright's Prairie houses.

Desarrollo profesional e investigación-acción en la enseñanza universitaria : un estudio de caso.

Analizar, mediante un estudio de caso, el desarrollo de un proceso de investigación-acción llevado a cabo por un grupo de profesores y profesoras de la Universidad de Oviedo bajo los planteamientos generales de la ciencia crítica de la educación, durante los dos primeros años de existencia del mismo. Un grupo de profesores de la Universidad de Oviedo durante los cursos 1990-1991 y 1991-1992, bajo los planteamientos generales de la ciencia crítica de la educación. Comienza con un estudio del marco teórico y metodológico, para pasar posteriormente al estudio de caso concreto que se apoya fundamentalmente en el análisis de los informes de investigación generados por el grupo. El estudio de caso incluye una fase de trabajo de campo y una fase de elaboración y discusión del informe de caso. Los instrumentos utilizados en el estudio han sido todos los materiales generados por el grupo a lo largo del proceso investigador, fundamentalmente informes. Análisis de dilemas de Winter. La investigación-acción reúne unas características que la hacen especialmente adecuada para la construcción de una nueva profesionalidad alternativa a la tradicional. La tarea que queda es la de seguir profundizando a través de los procesos de investigación-acción en el desarrollo teórico-práctico del trabajo de los docentes universitarios.

What is the Web? The Web Architecture

The Introductory Lecture is a discussion about "What is the Web". It involves lots of calling out TLAs and writing them on the blackboard, dividing things into servers, clients, protocols, formats, and the punchline is that the one unique and novel thing about the web is the hypertext link. This follows naturally into the Web architecture - the answer to the question "what is the web".
