Abstract
IT is well known that cross‐sections of a thin‐walled shell, unconstrained at the ends, do not necessarily remain plane under the action of an applied torque, but may undergo axial displacement or warp, as it is called.
The work involved in solving certain fixed‐fixed arch problems can be considerably reduced by adopting the clastic centre method.

Abstract
There is quite a lot of literature showing how to find the distribution of shear stress on a thin multi‐walled section under the action of an applied torque. In actual fact, however, before this torque can be assessed, it is necessary to know the position of the flexural axis of the section, the flexural axis being so positioned that when a shear is applied along it the section does not experience any torque. A method of finding the distribution of direct shear stress and hence the position of the flexural axis for a 2‐cell and then a 3‐cell section is explained.
The work involved in solving certain fixed‐fixed arch problems can be considerably reduced by adopting the classic centre method.

Abstract
When a complete fuselage ring, symmetrical about the ZZ axis, is under the action of a symmetrical loading system—the ring ABCD in FIG. 3.01 is one such example—it can be treated in two halves built‐in at D and cut at B, in the manner described earlier.

Abstract
MID‐SEPTEMBER, with the summer gone irrevocably, allows the librarian a fortnight of reflection time before the strenuous interests of autumn and winter become active. That is, if he returns stimulated in body and mind from a reasonable holiday and does not become immersed immediately in the almost compelling series of meetings of librarians arranged for the last fortnight of September and for October. For the student members the Birmingham Summer School remains in session until the 20th; for their elders ASLIB will confer at Swanwick from the 19th to 21st, and, in the same week‐end at Buxton, there will be the conference on library work for children; and, a week later, 26th to 29th, the University and Research Section will occupy Lady Margaret Hall at Oxford. The arrangements for October are set out in the L. A. Record. Their profusion embarasses many librarians. It is only natural that, as librarianship extends, every organized part of it becomes keenly aware of its individuality and, as the profession today grows more and more conference‐minded, few can keep step, save in a general way, with more than a fraction of the meetings arranged. Some effort is made by the L.A. and by librarians to preserve and strengthen the basic unity of all librarianship, but otherwise the diversity is great.

Abstract
Criticizes previous research on price/earnings ratios (PER) for neglecting their historical links with interest rates and analyses the causal links between interest ratres and the PERs of the Toronto Stock Exchange 300 Index (TSE300) and of seven major Canadian industries 1965‐1997. Explains the methodology and identifies three “distinct PER regimes”: 1965‐1974 (average PER 17.17), 1975‐1982 (average PER 8.92) and 1983‐1997 (average PER 17.2 with a higher standard deviation). Looks at the economic conditions for each period and suggests that current PERs “may not be too high”. Finds a negative correlation between PERs and treasury bill rates, differing between industries; and that the bill rate explains 95 per cent of PER variation for the TSE300, although it is not significant for the gold and silver industry. Adds that divided payout ratios and lower investor risk aversion are positively related to PERs, but that growth rate has a more variable influence. Summarizes the findings and their implications for PER forecasters.

Abstract
Die Redeweise von der «touristischen Explosion» in der jüngsten Gegenwart gehört ins «Wörterbuch des Unmenschen». Sie kennzeichnet aber drastisch einen Vorgang, dem eine Sprengwirkung nicht ganz abgesprochen werden kann. Jahrtausendalte Gewohnheiten der Sesshaftigkeit wurden seit rund 20 Jahren durch den Tourismus in einem früher unvorstellbaren Ausmass aufgebrochen. Die Erschütterung erfasste auch die Jugend. Das Beben pflanzt sich fort, zeitlich und räumlich, nicht etwa sich verebbend wie bei einem einzigen Erdstoss. Einmal in Schwung gesetzt, wurde der Tourismus allgemein, somit auch jener der Jugend, zu einem perpetuum mobile.

Abstract
Most academic libraries probably have in their collections, either in reference or as circulating titles, several of the works generally and rather imprecisely known as library handbooks or guides. These may include such standards as Jean Key Gates' Guide to the Use of Books and Libraries, now in its fourth edition, as well as more ephemeral efforts produced in‐house by the staffs of individual libraries and made commercially available to other institutions.
