Cognitive style related to the design process

This paper describes the development of a new version of Witkin's Group Embedded Figures Test (GEFT) and two further tests of a similar type using words and letters. The new form of the Group Embedded Figures Test Consists of a number of original two dimensional figures (complex and simple). Variations of the basic two dimensional figures were obtained by establishing a geometrical progression (from following a set of simple rules) to produce increasing degrees of complexity of the complex figures. This in turn generated more simple figures within them which were used in the test items.By using words and lettersas a means of generating embedded complex/simple shapes, not only are very different types of (overall) shape possible, but also the notion of field dependence/independence can (possibly) be applied to non-spatial (in the usual sense) modes of operating within the curriculum, i.e. the humanities as opposed to design and technology subject areas.     

Using proxies for the short rate: when are three months like an instant?

The dynamics of the unobservable short rate are frequently estimateddirectly using a proxy. We examine the biases resulting fromthis practice (the 'proxy problem'). Analytic results show thatthe proxy problem is not economically significant for single-factoraffine models. In the two-factor affine model of Longstaff andSchwartz (1992), the proxy problem is only economically significantfor pricing discount bonds with maturities of more than fiveyears. We also describe two different numerical procedures forassessing the magnitude of the proxy problem in a general interestrate model. When applied to a nonlinear single-factor model,they suggest that the proxy problem can be economically significant.     

Growth, crisis and change in the insurance industry: a retrospect

The insurance industry currently finds itself in a revolutionary situation characterized, in part, by the impact of new direct marketing techniques, facilitated by new technologies; by corporate restructuring and the creation of international mega-corporations; and by the accelerating globalization of the industry. This article surveys recent research on insurance history with the aim of placing these developments in their long-run context. Three areas are examined for evidence of continuities and discontinuities with the past: namely, the impact of technology, the interaction between markets and organizational change, and the globalization of insurance and its relationship to economic growth.     

The management of cross-disciplinary research

This paper is based on a critical review of the proceedings of the Second International Conference on Interdisciplinary Research held in 1981 in Manchester, England. Two sets of issues important for the management of collaborative research are identified. One is the need to remove ambiguities from the meanings of commonly used terminology, for which more precise definitions are proposed. Cross-disciplinary is used to describe only the nature of the task; multi- and inter-disciplinary are seen as describing alternative organizational ways of executing it. Which way should be used depends objectively on the circumstances.
The other set of issues is concerned with the effect institutional setting could have on the possibility of carrying out effective cross-disciplinary activity. Six different settings are identified and broad concepts of group dynamics are used to identify theoretical and practical problems and their possible solutions. The paper concludes with a survey of the practical implications for those managing cross-disciplinary research.
