Modelling default and likelihood reasoning as probabilistic

A probabilistic analysis of plausible reasoning about defaults and about likelihood is presented. 'Likely' and 'by default' are in fact treated as duals in the same sense as 'possibility' and 'necessity'. To model these four forms probabilistically, a logic QDP and its quantitative counterpart DP are derived that allow qualitative and corresponding quantitative reasoning. Consistency and consequence results for subsets of the logics are given that require at most a quadratic number of satisfiability tests in the underlying propositional logic. The quantitative logic shows how to track the propagation error inherent in these reasoning forms. The methodology and sound framework of the system highlights their approximate nature, the dualities, and the need for complementary reasoning about relevance

Organic Farming in Cornwall: Results of the 2002 Farmer Survey

A detailed survey of organic farming in Cornwall was completed duing the period August 2002 to February 2003. One of the main objectives of the survey was to describe current practices and constraints to organic production so as to aid the Organic Studies Centre in developing a research and training strategy that meets the needs of Cornish organic farmers. all 130 registered producer members of the Soil Association Certification Ltd (SACert) and Organic Farmers anf Growers Ltd (OF&G) were contacted. Of these, 120 were farming and 119 were interviewed. Data collected through closed questioning reflected a wide range of land-use, enterprise, marketing, husbandry, management, certification, income and environmental issues. Comments from farmers, recorded through open-ended questioning, are quoted and para-phrased throughout the report. The survey has provided the first detailed description of organic production in Cornwall. These data will be used by the Organic Studies Centre at Duchy College to form the basis of a strategy for organic farming research and development relevant to Cornwall. The information gathered will also be used to inform other parties concerned with development of the organic sector in the UK generally, at the south west of England specifically. A second follow-up survey will be conducted during 2005. This survey would not have been possible without the considerable efforts of the data collectors and the goodwill, time and expertise ofthe participating farmers. These contributions are gratefully acknowledged

Elaborate thinking from reading in the primary grades

Thesis (Ed.M.)--Boston UniversityElaborative thinking is an aspect of thought, a significant area in which creative minds are most active. Primary grade children often have vivid imaginations and elaborate on certain ideas. This ability sometimes may be lost as children grow and are taught adult methods of thought processes. It is the authors' hope to cultivate this ability of children to think imaginatively and creatively. Exercises in elaborative thinking have been constructed and successfully tried on intermediate grade children. No such exercises have been available to children in primary grades. The purpose of this study is to construct exercises in elaborative thinking for children in the primary grades, and to conduct an informal evaluation of them
