The Purpose and Process of Science: Contrasting Understandings in UK Research Establishments

This paper is based on an ESRC-funded study into scientists' perceptions of management. Changes in the organisation, purpose and process of science were heralded with the publication of the White Paper (Cm2250 1993). However, to date there has been little empirical work into how research scientists understand such issues. Our research, based on qualitative interviews conducted with scientist/managers in seven government-funded research establishments, found that scientists' notions of scientific purpose varied, not just according to the nature of their work, but also evolved as careers progressed and the contexts within which they worked changed (in particular as the need to generate income through commissioned work has increased). The data also reveal a diversity in scientists' understanding of the relationship between discovery and applied science. Of central importance to R&D managers is the extent to which these scientists saw their aspirations as achievable within the changing context of public sector science. From the data we generate an Ideal Type model of approaches that may be taken to reconcile the imperatives of applied and fundamental research and develop an understanding of the key role of senior management in creating an effective interface with external stakeholders and the development of culture and vision within the laboratory that will enable effective synergy.     

Some ideas and models in reliability theory

Summary Some questions about the meaning of reliability for the design of complex systems are discussed. Should the ideas of reliability be put in a broader framework, becoming applicable also to nontechnical systems, like a government organisation? In the mnd chapter some rather new failure models are reviewed and an interesting derivation of the Weibull distribution is discussed.     

Stockholder-bondholder conflict and dividend constraints

This paper examines a large, randomly chosen, sample of bond indentures focusing on the constraints they set on dividend payments that have the potential to transfer wealth from the bondholders (i.e., payments which are financed by a new debt issue or reduced investment). The nature of these restrictions support the hypothesis that bond convenants are structured to control the conflict of interest between stockholders and bondholders. Further, the empirical evidence suggests that these constraints are not binding — i.e., stockholders do not pay themselves as much dividends as they are allowed to. Explanations of this puzzling empirical regularity are suggested.     

Higher energy cost and the demand for restaurant services — a time-series analysis

Energy cost impact on demand for the restaurant services is examined using a broad base multi-variable regression model with special attention given to the lag structure and timing of the effects. The results reveal no negative impact of higher energy costs on demand. On the contrary, a slight positive delayed impact is evident over the short-run suggesting that, on margin, eating out may have been used as a compensatory recreational activity as a temporary substitute to other, more energy intensive, recreational activities.
