This paper details the development of a rapid tooling manufacturing route for the gravity and high‐pressure die‐casting industries, resulting from an EPSRC funded collaborative research project between the Universities of Warwick, Loughborough and DeMontfort, with industrial support from, amongst others, MG Rover, TRW Automotive, Sulzer Metco UK Ltd and Kemlows Diecasting Products Ltd. The developed process offers the rapid generation of mould tools from laser‐cut laminated sheets of H13 steel, bolted or brazed together and finish machined. The paper discusses the down‐selection of materials, bonding methods and machining methods, the effect of conformal cooling channels on process efficiency, and the evaluation of a number of test tools developed for the industrial partners. The paper also demonstrates the cost and time advantages (up to 50 and 54 per cent, respectively) of the tooling route compared to traditional fabrication methods.

The aim of this study is to demonstrate the benefit of design flexibility afforded by the Arcam free‐form fabrication process in the direct manufacture of injection mould inserts with complex cooling channel configurations and the process efficiency and quality gains achieved through using such inserts.

The manufacturing process of a flood cooled injection mould insert using the Arcam EBM S12 layered manufacturing process is presented. The insert is then evaluated against two other inserts (one un‐cooled and one traditionally baffle cooled (BC)) in the manufacture of test components, with the temperature of the insert and components recorded. The process conditions were adjusted (reduced cooling time) to increase the core and component temperatures to identify the operational limits of the inserts. Thermal imaging was employed to visualize the thermal distribution within the BC and flood cooled (FC) inserts.

The cooling efficiency of the FC insert was found to be significantly higher than that of the other two inserts, and the homogeneity of the heat distribution of the FC insert was more even than the BC insert. It was possible to manufacture non‐deformed components using the FC insert with zero cooling time (ejection immediately after removal of holding pressure), this was not possible with the BC insert.

Provides a basis for the development of more efficient and thermally homogeneous inserts through the Arcam EBM process.

Provides a technology/process for the manufacture of highly efficient core inserts for injection moulding, offering the industry a competitive advantage through the potential for time and cost savings and higher quality components.

This is the first direct comparison of an Arcam EBM manufactured insert with complex cooling geometries against traditionally cooled inserts, particularly novel is the thermal imaging analysis of the cooling efficiency and distribution.

Research suggests effective immersive simulations that rely on augmented reality enhance teachers’ self-efficacy and skills (Badiee & Kauffman, 2015). However, there is a gap in the literature as studies have largely ignored their uses in educational leadership programs (Bradley & Kendall, 2015). This study investigated the relationship between application of critical skills within an immersive simulation environment and 26 school or district leaders’ perceptions of self-efficacy in leading a professional learning community (PLC). Two overarching themes materialized from participants: improved general confidence in leading a PLC, and a sense of refined or expanded skills in the context of new approaches to leading PLC. Further studies are needed on the use of immersive simulation as a pedagogical tool and to examine impact for educational leadership practitioners.

We observe with pleasure that the French Analytical Control, which is known as the Controle Chimique Permanent Français, continues to make satisfactory progress. The value and importance of the system of Control cannot fail to meet with appreciation in France—as it cannot fail to meet with appreciation elsewhere—so soon as its objects and method of working have been understood and have become sufficiently well known. From the reports which appear from time to time in l'Hygiène Moderne, the organ of the French Control, it is obvious that a number of French firms of the highest standing have grasped the fact that to place their products on the market with a permanent and authoritative scientific guarantee as to their nature and quality, is to meet a growing public demand, and must therefore become a commercial necessity. An ample assurance that the Controle Chimique Permanent Français is a solid and stable undertaking is afforded by the facts that it is under the general direction of so distinguished an expert as M. Ferdinand Jean and that he is assisted by several well‐known French scientists in carrying out the very varied technical work required.

THE catalogue, as a library appliance of importance, has had more attention devoted to it than, perhaps, any other method or factor of librarianship. Its construction, materials, rules for compilation and other aspects have all been considered at great length, and in every conceivable manner, so that little remains for exposition save some points in the policy of the catalogue, and its effects on progress and methods. In the early days of the municipal library movement, when methods were somewhat crude, and hedged round with restrictions of many kinds, the catalogue, even in the primitive form it then assumed, was the only key to the book‐wealth of a library, and as such its value was duly recognized. As time went on, and the vogue of the printed catalogue was consolidated, its importance as an appliance became more and more established, and when the first Newcastle catalogue appeared and received such an unusual amount of journalistic notice, the idea of the printed catalogue as the indispensable library tool was enormously enhanced from that time till quite recently. One undoubted result of this devotion to the catalogue has been to stereotype methods to a great extent, leading in the end to stagnation, and there are places even now where every department of the library is made to revolve round the catalogue. Whether it is altogether wise to subordinate everything in library work to the cult of the catalogue has been questioned by several librarians during the past few years, and it is because there is so much to be said against this policy that the following reflections are submitted.

The Departmental Committee appointed to inquire into the use of preservatives and colouring matters in the preservation and colouring of food, have now issued their report, and the large amount of evidence which is recorded therein will be found to be of the greatest interest to those concerned in striving to obtain a pure and unsophisticated food‐supply. It is of course much to be regretted that the Committee could not see their way to recommend the prohibition of all chemical preservatives in articles of food and drink; but, apart from this want of strength, they have made certain recommendations which, if they become law, will greatly improve the character of certain classes of food. It is satisfactory to note that formaldehyde and its preparations may be absolutely prohibited in foods and drinks; but, on the other hand, it is suggested that salicylic acid may be allowed in certain proportions in food, although in all cases its presence is to be declared. The entire prohibition of preservatives in milk would be a step in the right direction, although it is difficult to see why, in view of this recommendation, boric acid should be allowed to the extent of 0·25 per cent. in cream, more especially as by another recommendation all dietetic preparations intended for the use of invalids or infants are to be entirely free from preservative chemicals; but it will be a severe shock to tho3e traders who are in the habit of using these substances to be informed that they must declare the fact of the admixture by a label attached to the containing vessel. The use of boric acid and borax only is to be permitted in butter and margarine, in proportions not exceeding 0·5 per cent. expressed as boric acid, without notification. It is suggested that the use of salts of copper in the so‐called greening of vegetables should not be allowed, but upon this recommendation the members of the Committee were not unanimous, as in a note attached to the report one member states that he does not agree with the entire exclusion of added copper to food, for the strange reason that certain foods may naturally contain traces of copper. With equal truth it can be said that certain foods may naturally contain traces of arsenic. Is the addition of arsenic therefore to be permitted? The Committee are to be congratulated upon the result of their labours, and when these recommendations become law Great Britain may be regarded as having come a little more into line— although with some apparent reluctance—with those countries who regard the purity of their food‐supplies as a matter of national importance.

The heady system of high‐pressure Continental air that drifted across the Atlantic and collided with the traditional cyclonic patterns of U.S. literary academe in the mid‐1960s precipitated a “Theory Revolution” that has brought a couple of decades of stormy and stimulating weather to the campus. The collision has produced occasionally furious debate and resulted for higher education in the kind of public attention customarily reserved for athletic scandals; it has kept tenuring processes in turmoil and publish‐or‐perish mills working round the clock.

This article compares the use of deep packet inspection (DPI) technology to the use of cookies for online behavioral advertising (OBA), in the form of two competing paradigms. It seeks to explain why DPI was eliminated as a viable option due to political and regulatory reactions whereas cookies technology was not, even though it raises some of the same privacy issues.

The paradigms draw from two-sided market theory to conceptualize OBA. Empirical case studies, NebuAd's DPI platform and Facebook's Beacon program, substantiate the paradigms with insights into the controversies on behavioral tracking between 2006 and 2009 in the USA. The case studies are based on document analyses and interviews.

Comparing the two cases from a technological, economic, and institutional perspective, the article argues that both paradigms were equally privacy intrusive. Thus, it rejects the generally held view that privacy issues can explain the outcome of the battle. Politics and regulatory legacy tilted the playing field towards the cookies paradigm, impeding a competing technology.

Shifting the narrative away from privacy to competing tracking paradigms and their specific actors sheds light on the political and the regulatory rationales that were not considered in previous research on OBA. Particularly, setting forth institutional aspects on OBA – and DPI in general – the case studies provide much needed empirical analysis to reassess tracking technologies and policy outcomes.
