An h‐adaptive finite element code for solving coupled Navier‐Stokes and energy equations is used to solve the thermally driven cavity problem for Rayleigh numbers at which no steady state exists (greater than 1.9 × 10⁸). This problem is characterised by sharp thermal and flow boundary layers and highly advection dominated transport, which normally requires special algorithms, such as streamline upwinding, to achieve stable and smooth solutions. It will be shown that h‐adaptivity provides a suitable solution to both of these problems (sharp gradients and advection dominated transport). Adaptivity is also very effective in resolving the flow physics, characterised by unsteady internal waves, are calculated for three Rayleigh numbers; 2 × 10⁸, 3 × 10⁸ and 4 × 10⁸ using a Prandtl number of 0.71 and results are compared with other published results.

An h‐adaptive finite element code for solving coupled Navier‐Stokes and energy equations is used to solve the thermally driven cavity problem. The buoyancy forces are represented using the Boussinesq approximation. The problem is characterised by very thin boundary layers at high values of Rayleigh number (>10⁶). However, steady state solutions are achievable with adequate discretisation. This is where the auto‐adaptive finite element method provides a powerful means of achieving optimal solutions without having to pre‐define a mesh, which may be either inadequate or too expensive. Steady state and transient results are given for six different Rayleigh numbers in the range 10³ to 10⁸ for a Prandtl number of 0.71. The use of h‐adaptivity, based on a posteriori error estimation, is found to ensure a very accurate problem solution at a reasonable computational cost.

The management of children′s literature is a search for value and suitability. Effective policies in library and educational work are based firmly on knowledge of materials, and on the bibliographical and critical frame within which the materials appear and might best be selected. Boundaries, like those between quality and popular books, and between children′s and adult materials, present important challenges for selection, and implicit in this process are professional acumen and judgement. Yet also there are attitudes and systems of values, which can powerfully influence selection on grounds of morality and good taste. To guard against undue subjectivity, the knowledge frame should acknowledge the relevance of social and experiential context for all reading materials, how readers think as well as how they read, and what explicit and implicit agendas the authors have. The good professional takes all these factors on board.

Employees are increasingly speaking out against their employer on relevant social issues, which raises the human factor to a next level in organisational affairs. The aim of this chapter is to shed light on the concept of employee activism and locate it in the academic and professional discussion about employees' active role as organisational communicators. After scrutinising some of the most popular cases from recent years, the relevant literature in the fields of social activism and employee communication as well as strategic organisational communication and public relations is critically reviewed with the idea to (1) provide a terminological clarification regarding employee activism, (2) outline the unique characteristics of its current forms, (3) discuss several factors that may trigger externally directed employee activism and (4) elaborate on the communicative nature of this phenomenon as well as its implications for organisational development and reputation. As a result, five propositions are suggested to explain what constitutes employee activism as a specific form of employee communication behaviour. The chapter also calls particular attention to related risks and opportunities for organisations and opens up questions for further research.

“WE come now to another aspect of the question, and it must be admitted that the resource and ingenuity of the opposition have left nothing unnoticed. This is the common and constantly repeated assertion that novels are so cheap that every working man in the country can buy all he needs for less than the annual library rate. This statement was first made some years ago when publishers commenced to issue cheap reprints of non‐copyright novels at 1s. and 6d. each. Previous to this the halfpenny evening paper had been relied upon as affording sufficient literary entertainment for the working man, but when it was found to work out at 13s. per annum, as against a library rate of 1od. or 1s. 4d., the cheap newspaper argument was dropped like a hot cinder. We doubt if the cheap paper‐covered novel is any better. Suppose a workman pays £20 per annum for his house, and is rated at £16, he will pay 1s. 4d. as library rate, or not much more than 1¼d. per month for an unlimited choice of books, newspapers and magazines. But suppose he has to depend on cheap literature. The lowest price at which he can purchase a complete novel of high quality by any author of repute is 3d., but more likely 4½d. or 6d. However, we will take 3d. as an average rate, and assume that our man has leisure to read one book every fortnight. Well, at the end of one year he will have paid 6s. 6d. for a small library by a restricted number of authors, and it will cost him an additional 4s. or 5s. if he contemplates binding his tattered array of books for future preservation. Besides this, he will be practically shut off from all the current literature on topics of the day, as his 3d. a fortnight will hardly enable him to get copyright books by the best living authors. With a Public Library at his command he can get all these, and still afford to buy an occasional poet or essayist, or novel, or technical book, well bound and printed on good paper, such as his friend who would protect him against an iniquitous library rate would not blush to see on his own shelves. It seems hard that the working men of the country should be condemned to the mental entertainment afforded by an accumulation of pamphlets. Literature clothed in such a dress as gaudy paper covers is not very inspiring or elevating, and even the most contented mind would revolt against the possession of mere reading matter in its cheapest and least durable form. The amount of variety and interest existing among cheap reprints of novels is not enough, even if the form of such books were better. It is well known to readers of wide scope that something more than mere pastime can be had out of novels. Take, for example, the splendid array of historical novels which have been written during the present century. No one can read a few of these books without consciously or unconsciously acquiring historical and political knowledge of much value. The amount of pains taken by the authors in the preparation of historical novels is enormous, and their researches extend not only to the political movements of the period, but to the geography, social state, costume, language and contemporary biography of the time. Thus it is utterly impossible for even a careless reader to escape noticing facts when presented in an environment which fixes them in the memory. For example, the average school history gives a digest of the Peninsular War, but in such brief and matter of fact terms as to scarcely leave any impression. On the other hand, certain novels by Lever and Grant, slipshod and inaccurate as they may be in many respects, give the dates and sequence of events and battles in the Peninsula in such a picturesque and detailed manner, that a better general idea is given of the history of the period than could possibly be acquired without hard study of a heavy work like Napier's History. It is hardly necessary to do more than name Scott, James, Cooper, Kingsley, Hugo, Lytton, Dumas, Ainsworth, Reade, G. Eliot, Short‐house, Blackmore, Doyle, Crockett and Weyman in support of this claim. Again, no stranger can gain an inkling of the many‐sided characteristics of the Scot, without reading the works of Scott, Ferrier, Galt, Moir, Macdonald, Black, Oliphant, Stevenson, Barrie, Crockett, Annie Swan and Ian Maclaren. And how many works by these authors can be had for 3d. each? The only way in which a stay‐at‐home Briton can hope to acquire a knowledge of the people and scenery of India is by reading the works of Kipling, Mrs. Steel, Cunningham, Meadows Taylor, and others. Probably a more vivid and memory‐haunting picture of Indian life and Indian scenery can be obtained by reading these authors than by reading laboriously through Hunter's huge gazetteer. In short, novels are to the teaching of general knowledge what illustrations are to books, or diagrams to engineers, they show things as they are and give information about all things which are beyond the reach of ordinary experience or means. It is just the same with juvenile literature, which is usually classed with fiction, and gives to that much‐maligned class a very large percentage of its turnover. The adventure stories of Ballantyne, Fenn, Mayne Reid, Henty, Kingston, Verne and others of the same class are positive mines of topographical and scientific information. Such works represent more than paste and scissors industry in connection with gazetteers, books of travel and historical works; they represent actual observation on the part of the authors. A better idea of Northern Canada can be derived from some of Ballantyne's works than from formal topographical works; while the same may be said of Mexico and South America as portrayed by Captain Mayne Reid, and the West Indies by Michael Scott. The volume of Personal Reminiscences written by R. M. Ballantyne before he died will give some idea of the labour spent in the preparation of books for the young. The life of the navy at various periods can only be learned from the books of Smollett, Marryat and James Hannay, as that of the modern army is only to be got in the works of Lever, Grant, Kipling, Jephson, “John Strange Winter” and Robert Blatchford.

Klaus Schmidbauer presented a paper entitled “On the Price Structure in Consumer Markets: Results of a Secondary Analysis of Price Comparisons of Consumer Durables”. The paper analysed price data on consumer durables collected by the German Institut für angewandte Verbraucherforschung in order to throw some light on two important issues in consumer policy. First, Schmidbauer considered the shape and form of the distributions of prices of given makes and models of consumer durables found in local markets. Inspection of these empirical distributions permitted the author to reach some conclusions about the usefulness of providing price comparison information on a public good basis. Secondly, the variety of different prices on offer in a local market (as measured by the coefficient of variation) was suggested as a measure of local price competition. Simple correlations were found between the number of prices quoted for a model and the range of those prices (positive); the average variability of prices between sellers and the price level in a given local market (negative); and the size of the local market and the price level (negative). Overall these results were taken as confirming the notion that increased price competition is reflected in an increased variation in price.

This paper reviews the prospect of a radical redefinition of the relationship between society, technology, and Nature as posited within Paolo Soleri’s Arcology theory, and anticipates a transformative social order and environmental setting in support of sustainability as demonstrated within the urban laboratory Arcosanti. It locates the roots of Soleri's ecological architecture within a rejection of urban sprawl emerging from his early apprenticship with Frank Lloyd Wright at Taliesin West in Arizona, and argues that his own theoretical model, in presenting a fusion of architecture and ecology, prefigures a utopia of transcendence and offers a more rational planned response to the challenges of our age, while offering environmental movements a vision of what a sustainable urban future might look like. The paper argues that the positive utopian tendencies in Soleri’s work should be reaffirmed and, at the same time, it underlines an urgent need for multi-aspect and multi-disciplinary research, and postgraduate education, to be undertaken at Arcosanti, to test the parameters of micro- and macro-structures within alternative models of ecological design. In concluding the paper gives acknowledgement to the ongoing work of the Cosanti Foundation’s Board of Directors and its new Strategic Plan Steering Committee, and their commitment to attract renewed levels of financial and human resource in support of the urban laboratory’s unfinished business.

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.
