Knowledgebases as structured theories
1988According to the structural paradigm of knowledge representation, knowledgebases are built by organizing facts along the semantic primitives of a conceptual modelling approach. Previous work of the authors has shown how these organizational principles can be brought into the logical view of knowledge representation by defining mechanisms for developing

A Structural Theory of Derivations
2018Operations which take in tuples of syntactic objects and assign them output syntactic objects are used to formalize the generative component of most formal grammars in the minimalist tradition. However, these models do not usually include information which relates the structure of the input and output objects explicitly.

Physical Review, 1955
Die relativistischen Korrekturen für die in die HFS eingehenden Ein-Elektronen-Integrale werden normalerweise mit dem reinen Coulomb-Feld des Kerns berechnet. Abweichend wird in der vorliegenden Arbeit die Abschirmung des Leuchtelektrons durch die inneren Elektronen mittels eines ortsabhängigen Korrekturfaktors im Coulomb-Potential berücksichtigt.

Theory of Dissipative Structures
1973One of the main reasons to develop thermodynamics beyond the equilibrium range lies in the need for a physico-chemical basis of biological order. Not only would one like to explain the maintenance of low entropy situations and subtle metabolic regulation processes but also one wants to provide a physico-chemical basis of evolution towards structures of

Bulletin of the London Mathematical Society, 1987
The aim of this paper is to give an approach to Shelah's classification theory. The author has the sure hope that the ideas of classification theory will find good applications beyond the confines of model theory. So he discusses them in the form of pictures, sometimes rather vague, of how things ought to be. The paper is built around eleven ideas. The

The Structure of Developmental Theory
1991This paper explores the thesis that any theory is generated out of a matrix of philosophical values. Evaluations of theories of development presuppose the acknowledgement that any theory emerges from an ontological and epistemological realist matrix, or, from an epistemological rationalist matrix.

FINANCIAL STRUCTURE AND THE THEORY OF PRODUCTION
The Journal of Finance, 1970ANY BUSINESS ENTERPRISE in the course of its operations must make at least three kinds of distinct decisions. First, it must decide upon a production plan-i.e., how much to produce and the choice of productive factors by which this may be optimally achieved.

An Illustration of the Power of Structure Theory
Applied Categorical Structures, 2000This article contains a sampling of applications of the theory of compact topological semigroups to diverse branches of mathematics. The theory of compact semigroups with one-sided continuity can be used effectively in Ramsey theory; this is illustrated with a semigroup proof of van der Waerden's theorem on arithmetic progressions.
