Relevance Logic and Entailment

- J. Dunn
- Computer Science
- 1986

Note carefully that the title of this piece is not ‘A Survey of Relevance Logic’. Such a project would be impossible given the development of the field and even the space limitations of this… Expand

Intuitive semantics for first-degree entailments and ‘coupled trees’

- J. Dunn
- Philosophy
- 1 March 1976

Classically, an argument A therefore B is ‘valid’ (or A is said to ‘entail’ B) if and only if (iff) each situation (model) is such that either A is false or B is true. This fits well with so-called… Expand

TLDR

Canonical extensions and relational completeness of some substructural logics*

- J. Dunn, M. Gehrke, Alessandra Palmigiano
- Mathematics, Computer ScienceJournal of Symbolic Logic
- 1 September 2005

Abstract In this paper we introduce canonical extensions of partially ordered sets and monotone maps and a corresponding discrete duality. We then use these to give a uniform treatment of… Expand

The Effect of Peer Tutors on Motor Performance in Integrated Physical Education Classes

- Cathy Houston-Wilson, J. Dunn, H. Mars, J. McCubbin
- Psychology
- 1 October 1997

The effect of untrained and trained peer tutors on the motor performance of students with developmental disabilities in integrated physical education classes was studied. This study used a… Expand

Partiality and Its Dual

- J. Dunn
- Mathematics, Computer ScienceStud Logica
- 1 October 2000

This paper explores allowing truth value assignments to be undetermined or "partial" (no truth values) and overdetermined or "inconsistent" (both truth values), thus returning to an investigation of… Expand

Star and Perp: Two Treatments of Negation1

- J. Dunn
- Philosophy
- 1993

The first uses a unary operation * ("star") on some underlying set of "states" ("worlds," "situations," "set-ups," "cases," whatever). The second definition uses a binary relation I ("perp") on such… Expand

Generalized Galois Logics: Relational Semantics of Nonclassical Logical Calculi

Nonclassical logics have recently played an increasing role in disciplines ranging from mathematics and computer science to linguistics and philosophy. "Generalized Galois Logics" develops a uniform… Expand
