Explains that stereolithography (SL) can greatly reduce initial tooling costs, thus making prototyping and small production runs economically feasible. Describes how epoxy resin SL5170 and Zeneca filled resin are used to build SL injection moulding tools. Different sets of tools were evaluated, based on the maximum number of successful injections and quality of performance. A polymer tool requires a minimum level of strength, thermal conductivity and dimensional accuracy. The Zeneca SL tool achieved a total number of 200 successful injections before starting to fail. However, the failure happened during the first shot of the day where the initial injection pressure was set high. On the other hand, epoxy tools were more resistant to injection pressure and temperature and more than 500 injections were achieved without tool failure. In all tests the cavity was never damaged and it was the core which failed during either injection or ejection. Concludes that product diversity, high product complexity, increase in product variety, and shorter product life are prime motives for SL tooling.

Reviews, for the USA, Europe and Japan, the current state of development and application of rapid prototyping techniques and their impact on time‐to‐market for new products. These techniques, which are still undergoing rapid development, have already had a dramatic effect on reducing the time‐to‐market for new products by between 60 per cent and per cent and on reducing the cost‐to‐market by between 40 per cent and 70 per cent. Concludes that although the US is ahead of the rest of the world in terms of depth of experience and range of techniques, Europe and Japan are catching up fast in terms of experience and applications. Gives guidelines for the managers of manufacturing companies on the importance of the techniques, the selection of the most appropriate system and how to obtain most of the techniques adopted.

In this study we demonstrate how the Health of the Nation Outcomes Scales for secure and forensic service users (HoNOS‐secure) tracks risk and recovery in men with mental illness and men with learning disability in a secure care pathway. Total and individual HoNOS‐secure item ratings made by multi‐disciplinary teams across the course of a period of admission (mean 15 months) for 180 men were examined. There was significant positive change on the clinical and risk‐related scales of HoNOS‐secure for patients in the learning disability care pathway (N = 48) between initial and final ratings. In the mental health care pathway (N = 132 patients) an apparent lack of change masked a more complex picture, where initial decline in HoNOS‐secure ratings was succeeded by significant improvement. Results suggest that it is challenging to measure clinical and risk‐related medium‐term clinical outcomes objectively for these patients, particularly in relation to core issues of treatment of mental disorder, and reduction of both problem behaviour and risk to others. However, it is important that practitioners continue to strive to demonstrate the benefits of care and treatment through appropriate outcomes measures.

SOME twenty five years ago, in my late teens, poking about in a very dirty second hand bookshop of the sort which seem virtually to have disappeared nowadays, I came across a volume which had been very lovingly, and very clumsily rebound by hand in orange and brown morocco. It stood out from the nineteenth century sermons and the early twentieth century adventures in the Raj like some exotic tropical fruit. I took the book from the shelves and found that the front cover had on it a rather roughly executed plant design in blind. The raised bands of the spine were finished off with a small leaf design, and at the top of the spine on a dark brown and heavy label which I discovered later covered a messy attempt at tooling was the title of the book, The roadmender, in gilt. The title was also in blind on the front cover at the top and slightly askew. It was a dull day outside, and in the gloom of the shop, lit by one measly unshaded bulb, the book actually did seem to take on a luminous quality, but it was the fact that someone had clearly spent so much loving time on rebinding that made me buy it. I reasoned that if someone cared so much for what the contents had to say, either to rebind the book specially, or have to rebind it because of wear and tear, it might be worth reading. It was priced at one shilling—more than I was used to forking out in that type of shop where twopence (d) was the sort of money I anticipated paying in the days before inflated book prices. The title of the book meant nothing to me, and the name of the author—Michael Fairless—rang no literary bell in my head. But I bought it, and took it home.

THE greatly increased interest in historical studies since the second world war has been, I hope, a welcome challenge to librarians, but it has been very difficult to meet it. That the librarians of our new universities should have had little research material to offer was only to be expected. Unfortunately, research scholars have discovered that our older libraries were also deficient, that source materials had either not been purchased, in the years when they were readily available, or had been acquired only to be discarded at a later date. Recently, therefore, both old libraries and new have found themselves in competition for a small and dwindling supply of out‐of‐print publications.

I suppose that most noticeable of all the changes in our profession since I came into it has been the multiplicity of the methods by which one can become a librarian. A. E. Standley says in a recent article in the L.A.R., in 1970: “The term librarian includes the Library Association chartered librarian, the graduate with a degree in librarianship, the scholar librarian, the information and intelligence officer, the translator, the abstracter, the non‐library‐qualified subject expert”.

Drawing upon Alfred Sohn-Rethel's work, we argue that, just as capitalism produces abstract labor, it coproduces both abstract mind and abstract life. Abstract mind is the split between mind and nature and between subject/observer and observed object that characterizes scientific epistemology. Abstract mind reflects an abstracted objectified world of nature as a means to be exploited. Biological life is rendered as abstract life by capitalist exploitation and by the reification and technologization of organisms by contemporary technoscience. What Alberto Toscano has called “the culture of abstraction” imposes market rationality onto nature and the living world, disrupting biotic communities and transforming organisms into what Finn Bowring calls “functional bio-machines.”
