Motivation gains on divisible conjunctive group tasks

Construction of Group Divisible Designs

Research Note: The Accuracy of Group Majorities for Disjunctive and Conjunctive Decision Tasks

For complex group decision tasks which can be described in terms of establishing the truth value of conjunctive (and) or disjunctive (or) composite propositions, the advantage for group judgmental accuracy of disaggregating the decision task into separate individual evaluations of the truth value of each component atomic proposition in the composite is investigated. For true propositions it is ...

Who Gains from Achievement Motivation Training?

Karoly Varga is Senior Research Fellow at the Sociological Research Institute of the Hungarian Academy of Sciences. He was recently involved in an evaluation of achievement motivation training programmes in several countries on behalf of UNI DO. Since the first experiment in India by McCelland and Winter (1969), work on achievement motivation development has been attempted in various cultures, ...

Class-Uniformly Resolvable Group Divisible Structures I: Resolvable Group Divisible Designs

We consider Class-Uniformly Resolvable Group Divisible Designs (CURGDD), which are resolvable group divisible designs in which each of the resolution classes has the same number of blocks of each size. We derive the fully general necessary conditions including a number of extremal bounds. We present some general constructions including a novel construction for shrinking the index of a master de...

Further results on large sets of disjoint group-divisible designs

Chen, D., CC. Lindner and D.R. Stinson, Further results on large sets of disjoint group-divisible designs, Discrete Mathematics 110 (1992) 35-42. This paper is a continuation of a recent paper by Chen and Stinson, where some recursive constructions for large sets of group-divisible design with block size 3 arc presented. In this paper, we give two new recursive constructions. In particular, we ...
