An enduring concern of Robert Dreeben’s work is the conditions of classroom instruction (Dreeben [1968] 2002; Barr and Dreeben 1983; Dreeben and Barr 1988). Whether it is the conditions influencing classroom goodwill (Bidwell, Chapter 3, this volume) or the compositional effects on instructional methods, Dreeben repeatedly brings readers’ attention to how the social organization of schools rela...

Simple Library Thesaurus Alignment with SILAS

This paper describes a systemwritten in Cwhich employs the instancebased approach to ontology alignment of library thesauri. It computes relatedness relations between subsets of a library catalogue. Even a very basic method to calculate confidence in the found relation yields usable alignment results. 1 Presentation of the system 1.1 State, purpose, general statement The system in this paper (S...

Negabent Functions in the Maiorana-McFarland Class

Boolean functions which are simultaneously bent and negabent are studied. Transformations that leave the bent-negabent property invariant are presented. A construction for infinitely many bentnegabent Boolean functions in 2mn variables (m > 1) and of algebraic degree at most n is described, this being a subclass of the Maiorana– McFarland class of bent functions. Finally it is shown that a bent...
