This article presents a cohesive, empirically grounded categorization system differentiating the types of generalizations students constructed when reasoning mathematically. The generalization taxonomy developed out of an empirical study conducted during a 3-week teaching experiment and a series of individual interviews. Qualitative analysis of…

When classifying numbers as odd or even with left-right keypresses, performance is better with the mapping even-right/odd-left than with the opposite mapping. This linguistic markedness association of response codes (MARC) effect has been attributed to compatibility between the linguistic markedness of stimulus and response codes. In 2 experiments…

In this paper we use membership category analysis to examine the way an interviewee utilises category work in order to resist the possible accusation of being a bad mother and instead posit her mothering as ordinary. Through our analysis we explore the interactional work of ascribing and resisting categorisation organised through claims and…

Hierarchical classes (HICLAS) models constitute a distinct family of structural models for N-way N-mode data. All members of the family include N simultaneous and linked classifications of the elements of the N modes implied by the data; those classifications are organized in terms of hierarchical, if-then-type relations. Moreover, the models are…

It is aimed at students in library schools to familiarize them with the principles and techniques of the Universal Decimal Classification (UDC). The book can also be used as a manual for self-instruction in UDC for those unable to…

This review of the evolution of the Dewey Decimal Classification over past 30 years concentrates on three conflicts that have influenced recent developments: integrity of numbers versus keeping pace with knowledge; detailed bibliographic classification versus shelf location device; and national bias versus internationalization. Seven references…

A proposal for a computer-aided method of building up an indexing language is made. The method involves linking terms relevant to any special retrieval system into the UDC, via a video terminal, producing a hybrid thesaurus-classification. (5 references)
