“I want to move once I have got things straight”: Voluntary sector chief executives' career accounts

This article reports investigation into chief executives' career perceptions, experiences, and aspirations in small and mediumsized organizations in England, using career history and biographical narrative techniques. Career accounts from sixty chief executives—twenty‐seven women and thirty‐three men—were gathered and analyzed, drawing on career theory and typologies of career characterization. A typology for voluntary sector chief executives' career stances was developed: the Paid Philanthropists, the Careerists, and the Nonaligned. Within this typology, women chief executives appeared as predominantly Careerists, outnumbering male chief executives by two to one. Implications for developing career theory in voluntary sector contexts is discussed and directions for future research suggested.     

Management,Competition and Professional Practice: Medicine and the Marketplace

Within the context of the creation of the internal market for health care, the paper examines the role of clinical directors, that is doctors who have retained their professional clinical positions whilst at the same time assumed roles as managers within increasingly well-defined corporate organizations providing health care. This represents considerable change from previous contexts in which doctors could always contract out of difficult managerial decisions. The role of clinical director is examined in terms of its own directorate and its involvement in contracting, co-operation and competition both within its own corporate organization and within the wider market place for health. Key issues are raised for the individuals and organization by these changes, they are discussed in terms of time, succession, managing colleagues, financial and human resources, market behaviour, support and terms of reference. These changes occasion wider discussion in terms of the challenge of coping with future demands for innovation, changes in the distribution of power within an emerging market for health care and the relationship among health care organizations, professionals and lay clients.     

The physiological costs of flight capability in wing-dimorphic crickets

Nutritional indices, triglyceride levels and flight muscle developmental profiles were compared between long-winged (LW) and short-winged (SW; flightless) morphs of the cricketsGryllus rubens Scudder andG. firmus Scudder. This was done to identify potential physiological costs of flight capability in adults. The LW morph of each species converted a lower proportion of assimilated nutrients into biomass (reduced ECD) than did the SW morph. This documents increased respiratory metabolism in the LW morph. Triglyceride concentration was higher in LW vs. SW adults. This suggests that the elevated respiration in the LW morph may be at least partially due to the increased biosynthesis of this high energy substance. Preliminary data indicate higher respiration rates of LW functional vs. SW vestigial flight muscles. Collectively, these data suggest that the energetic cost of flight capability in adults results from biosynthesis of triglyceride flight fuel and flight muscle maintenance but not flight muscle growth. No flight muscle growth was observed in adults.     

Sources of Bias in the Recall of Self‐Generated Data: The Role of Anchoring1

This study examines two issues. First, we assess the reliability of employment data self‐generated by respondents using a survey panel of 280 firms surveyed in 1999 and again in 2002. Our results show that there is a close correlation between self‐generated and archival secondary data. Second, we test for bias in the recall of previous years' employment levels and the sources of such bias. We assess three reasons for recall bias: respondent‐level factors; firm‐level factors; and anchoring. Our regression results indicate that: owners and new respondents; those in firms that changed legal status and/or location; those in smaller firms; and those in growing or declining firms were biased in their recall of prior employment. In addition, growing firms tended to underestimate their growth, which points to anchoring as an explanation for these biases. These biases imply that we have to be careful in delineating performance measures and cautious about how we interpret self‐generated managerial information.     

Combinatorial analysis for route first-cluster second vehicle routing

Two Route first-cluster second vehicle routing algorithms are contrasted in the first section of the paper. Next, the ‘large’ number of feasible solutions to a multiple travelling salesman problem is established given that each salesman can visit any number of customers in a stated range. An approximate expression is given for the ‘small’ fraction of this solution space searched by a route first-cluster second vehicle routing heuristic. Nevertheless, this heuristic is seen to be a very efficient means of searching its solution space.     

Comparing products using data envelopment analysis

Using an application of linear programming known as Data Envelopment Analysis (DEA), a method is described to compare products which vary in excellence along a number of dimensions, and for each of which there might be a number of associated “costs”. The method is illustrated by comparing published benchmarks of 37 computer printers. Potential uses of a DEA analysis of products might be: to assist corporate buyers who may need to reconcile a diversity of present and future uses in one standardised purchase; in competitor analysis; in determining unexplored market niches; and as a normative model of product excellence against which product purchasing behaviour could be compared.     

Inventory control in hospital blood banks

The delicate relationship between donors and the Transfusion Service in the U.K. implies a clear duty to make the best possible use of the limited blood supplies, and this turns attention upon the stocking policies adopted by Hospital Blood Banks. Whereas Blood Bank staff can obtain an intuitive grasp of the effects of various stock levels for the common bloods, this is not usually the case for the rare bloods which are more difficult to control. A policy decision has to be made which balances the conflicting stock requirements of maintaining a high availability and also low out-dating rates. A Markovian structure is exploited in this paper for this purpose and the effects of the key variables are shown to be interrelated. In any particular instance the form of the probability distribution of demand between replenishments, the scale of the throughput, the blood life in relation to the ordering interval, the fraction of blood transfused and the fraction of the replenishment order which is supplied to the Bank will together determine the form of the operating characteristics.
