The 28th annual conference of Aslib, held at Nottingham University from 11th to 14th September, 1953, proved to be the largest that Aslib has so far organized. A list of those present is printed on pp. 254–260. Yet again Aslib was glad to be able to welcome a number of overseas guests and members, including Dr. and Mrs. Lancour and their small daughter from the U.S.A., Drs. and Mrs. van Dijk and Miss Rom from the Netherlands, Mr. M. S. Dandekar and Mr. J. V. Karandikar from India, Miss D. M. Leach from Canada, and Mrs. T. Collin from Norway. Mr. Walter A. Southern, a Fulbright scholar from the U.S.A. affiliated to Aslib during his year's study in the United Kingdom, represented the Special Libraries Association, and Mr. J. E. Holmstrom attended as an observer on behalf of Unesco.

This paper studies elastohydrodynamic lubrication (EHL) of line contacts for the slide‐roll ratios 0‐2 based on the assumptions of interfacial shear strength and interfacial slip. It is shown that the viscoelastic, viscoplastic and non‐continuum fluids distribute from the inlet zone to the Hertzian contact zone in order for a given operating condition when the load and rolling speed exceed critical values. For the rolling speed below the critical, the distributing fluids from the inlet zone to the Hertzian contact zone in order are viscoelastic and non‐continuum when the load exceeds a critical value. These show a multirheological behavior EHL film, formed in a contact, which may represent a mode of mixed lubrication. For this mode of lubrication, the fluid model should handle both inlet and Hertzian contact zones where the fluids are, respectively, continuum and non‐continuum. A new EHL analysis and theory, therefore needs to be established.

LOOKING BEFORE AND AFTER : BEFORE Opening, as we do, a new volume of THE LIBRARY WORLD, especially as with it we reach the venerable age of sixty‐one, does suggest retrospective and prospective view. The magazine is the oldest amongst independent library journals, though others existed before 1899 in different forms or under other titles than those by which they are known to‐day. When at the end of last century it was felt that utterances were needed about libraries, unfettered by uncritical allegiance to associations or coteries, librarianship was a vessel riding upon an official sea of complacency so far as its main organisation was concerned. It was in the first tide, so far as public libraries were concerned, of Carnegie gifts of buildings, not yet however at the full flood. The captains were men of the beginnings of the library voyage; who were still guided themselves by the methods and modes of the men who believed in libraries, yet feared what the public might do in its use of them. Hence the indicator, meant to show, as its name implies, what books were available, but even more to secure them from theft, and to preserve men and women from the violent mental reactions they would suffer from close contact with large numbers of books. There were rebels of course. Six years earlier James Duff Brown has turned his anvil shaped building in Clerkenwell into a safeguarded open access library in which he actually allowed people, properly vetted, to enter and handle their own property. This act of faith was a great one, because within a mile or so some 5,000 books had been lost from the Bishopgate Institute Library, which has open shelves, too, not “safeguarded”. Brown's “cave of library chaos” as a well‐known Chairman, who by one visit was convinced of its good sense and practicability, called it, focused the attention of scores of librarians—so much so that Brown had to beg them to keep away for about a year, so that the method might be better judged after sufficient trial. It also focused the attention of the inventors of the indicator, who, presumably, had more than a benevolent interest in its sales. So there was war against this threat and for several years this childish contention raged at conferences, in private conversations amongst library workers, and in letters to the press aimed to convict Brown and all his satellites of encouraging dishonesty, mental confusion and other maladies public. Hence Brown, L. Stanley Jast, William Fortune and others initiated this journal to teach librarians and library committees how libraries were to be run. That, in extreme brevity, is our genesis. For sixty years it has encouraged voices, new and old, orthodox or unorthodox, who had something to say, or could give a new face to old things, to use its pages. Brown was its first honorary Editor, and with some assistance in the later stages remained so for the thirteen years he had yet to live. Nearly every librarian of distinction in his day has at some time or other contributed to these pages. So much of our past may be said and we hope will be allowed.

This chapter presents an innovative learning opportunity for tourism students, International Tourism and Hospitality Academy at Sea, that has been in operation for the last 10 years. The program could render itself as a case study of Kolb’s experiential learning theory according to which knowledge is created by transforming experience. Its uniqueness and complexity lie in its diversity. This program has involved between 80 and 130 tourism students yearly from four to six institutions from different countries participating in new scholarly inputs by non-resident professors and instructors.

All measurements of EHD film thicknesses were carried out in simulated test machines. This study uses an actual bearing. A test rig which used a 65mm bore radial cylindrical roller bearing was constructed with a specially designed sapphire window in the outer track. Full loads, and speeds to 3000 rpm were applied. With specially polished rollers and chromic oxide coating on the window excellent interferometric film thickness measurements were found possible. A Xenon flash lamp was used and a Xenon Iaserof0–50pps,pulse half width of 150ns and peak power of 100 watts was developed for this research. A microscope and 35mm camera as well as video tape were used for recording results. Arrangements were made to study any chosen roller and the side of the bearing was also open to view. First the film measurements, when corrected for inlet zone viscous heating, agreed admirably with theoretical predictions for mid and exit film thickness. The effect of inlet boundary length on the film was then investigated in some depth. Studying the effect of the multiple roller system, a number of techniques were used to demonstrate that the inlet boundary length, which controls the lubricant film thickness, was itself controlled by the film thickness between the rollers and track in the unloaded zone. The ribs of oil, formed at either edge of the roller, are only secondary sources of oil for replenishment of the inlet film. It is in fact usual (as shown by the convex shape of the inletzone) for oil to feed out of the inlet zone into the ribs. Oil globules were sometimes observed riding on an air cushion at the entry to the roller‐track conjunction, though completely inoperative as providers of oil.

Since its launch in 2005, YouTube has provided a unique platform for users worldwide to share and engage with content, leading to a rise in user-generated content (UGC), especially among youth. One of the most prevalent, yet under-explored, subgenres of UGC is the user-generated music video, where users integrate music and images with an element of performance or narrative; the current research deploys longitudinal analysis to describe the trends in youth-created music videos and how these trends have evolved in the early years of YouTube. Using a sample of 100 youth-created user-generated music videos uploaded to YouTube in 2007 and 2013, the authors investigate trends in production strategies, narrative content, and demographics. Compared to videos posted in 2007, youth-created music videos posted in 2013 featured more complicated editing techniques, less linear narratives, younger actors, more women, and were more likely to celebrate the self, mimicking the recent emergence of “selfie culture.” These findings are discussed with respect to YouTube’s role in reducing barriers to entry and providing a virtual space for youth-oriented content communities that thrive on engagement and social networking as strategies of identity development.

This chapter outlines an augmented reality project developed as part of a master’s course on eTourism within a curriculum. It discusses opportunities to foster community engagement with local tourism actors and experiential learning for international students. It also contributes to the literature on experiential education in this field. Moreover, the chapter discusses cross-cultural learning implications as international students were asked to study a local destination. Results show how the introduction of a practical project into the tourism curriculum proved to provide better learning of the application of eTourism, and a powerful pedagogical approach to raise global citizenship awareness.

This chapter explains the background of the book and begins with an introduction of Jafar Jafari’s tremendous contribution to tourism knowledge creation and education. This is followed by a report on the content analysis of 573 tourism education related articles published in the past 10 years. Results indicated the need for philosophical discussion about the nature of tourism education and the popularity of teaching and learning approaches as a research topic. The two main sections of this book, namely philosophical issues in tourism education and experiential/active learning in tourism education, fit into these two identified issues. A synopsis of each chapter is provided next; and future directions for tourism education research are suggested.
