Abstract
Cell formation design in cellular manufacturing systems (CMS) has been the focus of recent manufacturing research literature. A great amount of research has been published addressing either technical issues (e.g. part‐machine grouping algorithms) or operational issues (e.g. planning and scheduling in the CMS). Research addressing strategic issues in cell formation design has been minimal. Addresses strategic considerations in cell formation design, specifically, the linkage and relationships between specific cell design issues and the firm′s competitive advantage in the marketplace. It is demonstrated that cell formation design decisions must be addressed in alignment with the firm′s strategic plan and manufacturing competitive priorities.

Abstract
The importance of reducing product lotsizes in converting traditional job shops into just‐in‐time (JIT) type manufacturing systems has been addressed in the literature. This paper presents a lotsize reduction model for closed stochastic production systems. The model is formulated based on an M/G/c queuing lotsize model. Product lotsize choice is related to all major components of job flow time: waiting time in queue, batch processing time, batch moving time, and finished goods warehousing time. The research is motivated by the fact that an optimal lotsize solution that minimizes only average job waiting time in the shop may not be optimal when the effects of job batch processing time, batch moving time, and batch warehousing time are also considered. There is no general closed form solution to the model due to the complexity of its nonlinear formulation. Based on the unique properties of the model, heuristic solution procedures are developed. The research demonstrates opportunities for shop managers to significantly reduce product lotsizes while minimizing total operating cost.

Abstract
OUR readers will, we trust, appreciate our double souvenir number issued in connection with the Library Association Conference at Glasgow. Special features are the articles on the Mitchell Library, Glasgow, 1874–1924, by a member of the staff, Mr. J. Dunlop, and one on the Burns Country, by Mr. J. M. Leighton, of Greenock Public Library. We printed the provisional programme in our July issue and as we go to press have little to add to the particulars there given, except to compliment the Library Association and the Local Reception Committee on the excellent programme arranged for the occasion, from both the professional and social point of view.

Abstract
WE offer our readers good wishes for 1939. We hope that every kind of library may be allowed in peace to pursue its development for the spreading of good reading, to the end that enlightenment and with it wisdom may prevail amongst our millions of readers. We hope too that it will be another year of progress in service, in good and deftly‐employed technique, in the development of the will to make libraries interesting, attractive, useful and indeed inevitable and essential to all men. For librarians we hope it may be a further stage in the promotion of their profession, of growth of their own faith in it, and of increase in the willingness of those who employ librarians in municipalities, counties, colleges and other places to recognize training and service with better pay, prospects and status. We know that appreciation will not give greater willingness to serve; we do know it will give greater happiness.

Abstract
Purpose
In spite of growing research interest in cyber security, inter-firm based cyber risk studies are rare. Therefore, this study aims to investigate cyber risk management in supply chain contexts.
Design/methodology/approach
Adapting a systematic literature review process, papers from interdisciplinary areas published between 1990 and 2017 were selected. Different typologies, developed for conducting descriptive and thematic analysis, were established using data mining techniques to conduct a comprehensive, replicable and transparent review.
Findings
The review identifies multiple future research directions for cyber security/resilience in supply chains. A conceptual model is developed, which indicates a strong link between information technology, organisational and supply chain security systems. The human/behavioural elements within cyber security risk are found to be critical; however, behavioural risks have attracted less attention because of a perceived bias towards technical (data, application and network) risks. There is a need for raising risk awareness, standardised policies, collaborative strategies and empirical models for creating supply chain cyber-resilience.
Research limitations/implications
Different types of cyber risks and their points of penetration, propagation levels, consequences and mitigation measures are identified. The conceptual model developed in this study drives an agenda for future research on supply chain cyber security/resilience.
Practical implications
A multi-perspective, systematic study provides a holistic guide for practitioners in understanding cyber-physical systems. The cyber risk challenges and the mitigation strategies identified support supply chain managers in making informed decisions.
Originality/value
To the best of the authors’ knowledge, this is the first systematic literature review on managing cyber risks in supply chains. The review defines supply chain cyber risk and develops a conceptual model for supply chain cyber security systems and an agenda for future studies.

Abstract
Remarks on the parallel in the basis of the riches of the aristocracy and plutocracy. Illustrates the argument from the history of the development of the cotton textile industry, the underpinnings for its growth being the inventions prior to and during the eighteenth century. Exemplifies the part of inventions as the begetter of plutocratic wealth. Sir Richard Arkwright, notably, was its salacious issue.

Abstract
IN the October number of THE BRITISH FOOD JOURNAL, while disclaiming any intention of supporting or opposing any political party or any section of politicians, we stated our opinion that the fiscal policy which has been outlined before the country by Mr. CHAMBERLAIN is eminently one which requires to be put to the test of experiment and which cannot be profitably argued about upon theoretical bases. In connection with the allegation that by following the policy of leaving our doors open to those who shut their own doors in our faces, we are able to obtain goods at less expense than would be the case under other conditions, we pointed out that it would be well for the public to consider whether that which is so cheap may not also, to a great extent, be particularly nasty. The desirability of considering the nature and quality of so‐called “ cheap ” foods, supplied to us by various countriies without restriction, does not, as yet, appear to have entered the heads of those who have made matter for political controversy out of what is, in reality, a scientific question. The facts are not sufficiently known, or, in consequence of the proverbial carelessness of our generation, are not clearly appreciated. And yet, as it seems to us, some of those facts are of paramount importance to those who desire to study the subject in a calm and scientific manner and outside the region of political turmoil. What do we get from the various countries whose producers and merchants are free to “dump” their goods in this country without the restrictive influence of duty payments? Great Britain has made it known to all the world that “Rubbish may be Shot Here,” and we venture to say that the fullest advantage has been taken, and is taken, of the permission. From America, France, Germany, Italy, Holland, and Belgium, in fact from every producing country—including now even Russia and Siberia, we get inferior or scientifically‐adulterated articles which are sold to the public “ cheap.” Milk and butter scientifically adulterated, or produced under improper conditions in such a way that their composition becomes the same as physically‐adulterated products, condensed “milk” minus cream, cheese practically devoid of fat, or “ filled ” (as it is called) with margarine, all reach us in enormous quantities from most of our near and dear neighbours. Butter and certain wines and beers, loaded with injurious ‘ preservative” chemicals and the sale of which is prohibited in the country of production, are sent to the easily‐entered British “dumping‐ground” for the delectation of its confiding inhabitants. “Tinned” foods prepared from raw materials of inferior character or of more than questionable origin, are copiously unloaded on our shores to feed our complaisant population,—instead of being consigned to the refuse destructors which should be their proper destination; while, every now and then, when something worse than usual has been supplied, representative specimens of this delectable class of preparation are proved to have caused outbreaks of violent illness—those so‐called ptomaine poisonings which, of late years, have increased in number and in virulence to so distinctly alarming an extent. Flour made from diseased or damaged grain, or itself “ sick ” or damaged, and so “ processed ” as to mask its real condition; flour, again, adulterated with other and inferior meals, are “ goods ” supplied to us in ample amount for the benefit of those whose mainstay is some form of bread or flour‐food. The list might be continued literally ad nauseam.
