“If I was going to design a chair,the last thing I would look at is a chair”: product analysis and the causes of fixation in students’ design work 11–16 years

Creativity is acknowledged to be important for economic growth and as an everyday life-skill, however several influential reports have suggested that education could do more to harness creative talent. Creative cognition literature suggests the lack of creativity is at least partly the result of ‘fixation’ (difficulty in generating novel ideas due to imagination being ‘structured’ by existing knowledge). This paper focuses on the secondary (students aged 11–16 years) design and technology (D&T) context in the UK. Here we examine whether teacher practice can contribute to fixation by focusing on one specific facet of teacher practice in D&T; the use of product analysis to inform the generation of creative design ideas. Data is drawn from the preliminary phase of a research and intervention project from interviews with D&T teachers (N = 14), students (N = 126) and lesson observations (N = 10) and an analysis of documents and student work. Product analysis is widely used at different points in design projects but, as is shown, in all cases current practice can lead to fixation, as thinking is constrained down specific paths and tasks are at best at procedural rather than comprehension level. The implications of these findings and tentative ways forward for practitioners are discussed.     

Riding the Third Wave Implications of Biotechnology for the Canadian Seed Crop Industry

Biotechnology is causing dramatic changes in the seed industry on a national and global level. Further, the delivery of technology through seed is affecting all aspects of crop production. Coined the Third Wave of Development, it is a drive to meet specific end use traits through biotechnology. In light of this, the industry is seeing increased integration between all those involved in the chain of production. Adapting to this new environment creates significant challenges for the industry, including regulatory, international, handling, and structural.
As the Canadian seed industry changes dramatically to meet the specific needs of end users, there has been an increase in strategic alliances between both handling and seed companies to accommodate identity preserved production. There has also been an increase in mergers and acquisitions, as R&D companies attempt to marry novel trait developments with good germplasm and seed production expertise.
Yet, this is only the beginning as the integration of the seed industry with other aspects of the crop inputs sector applies even more pressure to integrate the agri-food industry right from plant breeding through to end use.     

Commonality in Codes of Ethics

We create a database of company codes of ethics from firms listed on the Standard & Poor’s 500 Index and, separately, a sample of small firms. The SEC believes that “ethics codes do, and should, vary from company to company.” Using textual analysis techniques, we measure the extent of commonality across the documents. We find substantial levels of common sentences used by the firms, including a few cases where the codes of ethics are essentially identical. We consider these results in the context of legal statements versus value statements. While legal writing often mandates duplication, we argue that value-based statements should be held to a higher standard of originality. Our evidence is consistent with isomorphic pressures on smaller firms to conform.     

An alternative interpretation of the discontinuity in earnings distributions

We show that the asymmetric effects of income taxes and special items for profit and loss firms contribute to a discontinuity at zero in the distribution of earnings. Income taxes draw profit observations towards zero while negative special items pull loss observations away from zero. These earnings components are thus expected to contribute to a discontinuity even in the absence of discretion. We show our results are not an artifact of deflation and that other common components of earnings do not have similar effects on the earnings distribution around zero.

‘Gone to Gowings’ - An Analysis of Success Factors in Retail Longevity: Gowings of Sydney

Low productivity within service industries has been a major concern, but this situation is unlikely to improve without a general change in the way productivity is measured and managed. This paper aims to illustrate the value of stepwise data envelopment analysis (DEA) for measuring and benchmarking productivity. The issues and problems regarding productivity measurement as well as the advantages of using DEA in productivity measurement are analysed. The article extends current DEA applications by developing a stepwise approach to DEA. The latter technique combines correlation and DEA analysis for developing robust models and sound productivity measurement. The advantages of the proposed methodology are illustrated by applying it to a dataset of three-star hotels in the UK. Six inputs and three outputs are identified as the factors affecting rooms division efficiency in three star hotels.     

Tourism environments and management

The Congress of the World Leisure and Recreation Association, held in Sydney, Australia 16–19 July 1991, had as its focus the theme of ‘Leisure and tourism: social and environmental change’. Among over 140 papers on varied management, research and education issues a number examined the frameworks used to understand tourism environments and their management. Bill Bramwell, of the Centre for Tourism at Sheffield City Polytechnic, assesses the new insights offered by these papers.
