This paper presents a boundary element formulation for the transient Stokes equations in which the well known closed form fundamental solution to the steady Stokes equations is employed and the time derivative is taken to the boundary with dual reciprocity method. This approach has the advantage of simplicity of formulation and implementation in relation to the alternative boundary element schemes previously presented. In addition in this paper the dual reciprocity method is presented in a more formal mathematical way using well established interpolation theories which guarantee the convergence of the method. Results are presented for a series of three‐dimensional internal problems in which the accuracy of the method is shown.

The purpose of this paper is to present an inverse analysis procedure based on a coupled numerical formulation through which the coefficients describing non‐linear thermal properties of blood perfusion may be identified.

The coupled numerical technique involves a combination of the dual reciprocity boundary element method (DRBEM) and a genetic algorithm (GA) for the solution of the Pennes bioheat equation. Both linear and quadratic temperature‐dependent variations are considered for the blood perfusion.

The proposed DRBEM formulation requires no internal discretisation and, in this case, no internal nodes either, apart from those defining the interface tissue/tumour. It is seen that the skin temperature variation changes as the blood perfusion increases, and in certain cases flat or nearly flat curves are produced. The proposed algorithm has difficulty to identify the perfusion parameters in these cases, although a more advanced genetic algorithm may provide improved results.

The coupled technique allows accurate inverse solutions of the Pennes bioheat equation for quantitative diagnostics on the physiological conditions of biological bodies and for optimisation of hyperthermia for cancer therapy.

The proposed technique can be used to guide hyperthermia cancer treatment, which normally involves heating tissue to 42‐43°C. When heated up to this range of temperatures, the blood flow in normal tissues, e.g. skin and muscle, increases significantly, while blood flow in the tumour zone decreases. Therefore, the consideration of temperature‐dependent blood perfusion in this case is not only essential for the correct modelling of the problem, but also should provide larger skin temperature variations, making the identification problem easier.

In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.

THE Reference Department of Paisley Central Library today occupies the room which was the original Public Library built in 1870 and opened to the public in April 1871. Since that date two extensions to the building have taken place. The first, in 1882, provided a separate room for both Reference and Lending libraries; the second, opened in 1938, provided a new Children's Department. Together with the original cost of the building, these extensions were entirely financed by Sir Peter Coats, James Coats of Auchendrane and Daniel Coats respectively. The people of Paisley indeed owe much to this one family, whose generosity was great. They not only provided the capital required but continued to donate many useful and often extremely valuable works of reference over the many years that followed. In 1975 Paisley Library was incorporated in the new Renfrew District library service.

SO much controversy has raged around the subject of newsrooms in the past two years, that librarians are, as a rule, utterly tired of it, and the appearance of still another article upon the subject is not calculated to tone down the general spirit of vexation. It requires no little courage to appear in the arena in this year of Grace, openly championing those departments of our institutions which were originally intended to convey the news of the day in the broadest manner.

This chapter traces the history of diversity and inclusion efforts at the College of Information Studies at the University of Maryland as an example of an institution that has made diversity and inclusion central to its activities.

By exploring the successes and failures of a program that identifies itself as activist in terms of diversity and inclusion, this chapter offers a portrait of the evolution of cutting edge diversity and inclusion efforts in the field.

Widespread changes to the diversity and inclusiveness of library and information science education, professions, and institutions depend on all parts of the field committing to these issues, sharing ideas and best practices, and becoming activists for equity.

While granting Cowper the full poetic license he is entitled to, prosaically I must observe that it is not the syllables but rather the philogists who pant. They do indeed breathe rapidly in short gasps after they have established each successively deeper level of root connection in pursuit of the etymological purpose of delineating the origin and historical development of words, or of providing an account of any given word. Etymology as so defined I will designate analytic etymology and distinguish from another form of word study, which I shall call reconstructive etymology.

IT would, perhaps, be in the nature of a precedent for an Editorial to THE LIBRARY WORLD not to be devoted to an analysis of some topic of, or controversy over, librarianship. Possibly recklessly, the Editor has decided on this occasion to establish that precedent.

There has been a recent tendency for medical sociology to ignore the possible influence that religion may have on health. For example, religion as a social variable is now no longer routinely collected in large scale social surveys dealing with health or mortality. As Vaux speaking of America stated: “The U.S. Public Health Service, in its extensive and comprehensive analysis of health in its etiological and epidemiological dimensions, has chosen to systematically ignore the variable religion” (1,p.524). Such an attitude has been justified by recourse to arguments about the secularisation of society and in particular to the decline in the membership of the traditional churches. In this article I wish to re‐open this area for discussion by again asking the question: does religion influence health? The medical literature, from both national and ad hoc studies, considering the evidence of health effects under the headings of mortality, and physical and psychological morbidity will be reviewed. Religion however, when dealt with as a social science variable does have its problems; if correlations between religion and health are found how are they to be accounted for? I will, therefore, also look at the various types of causal mechanisms which have been put forward by researchers. Further, why certain diseases have greater prominence in the literature than others, and why certain religious groups have received greater attention than others will be considered. Finally the article concludes by outlining avenues of future research in the area and how any such work could avoid the theoretical bias of past studies.
