The use of fluoropolymer resin within ambient temperature curing exterior paint finishes for use on aircraft are shown to be a practical and beneficial proposition. Comparison with two‐component polyester polyurethanes and with acrylic urethanes clearly indicates superior durability in terms of gloss and colour retention.

There is a huge amount of information and data stored in publicly available online databases that consist of large text files accessed by Boolean search techniques. It is widely held that less use is made of these databases than could or should be the case, and that one reason for this is that potential users find it difficult to identify which databases to search, to use the various command languages of the hosts and to construct the Boolean search statements required. This reasoning has stimulated a considerable amount of exploration and development work on the construction of search interfaces, to aid the inexperienced user to gain effective access to these databases. The aim of our paper is to review aspects of the design of such interfaces: to indicate the requirements that must be met if maximum aid is to be offered to the inexperienced searcher; to spell out the knowledge that must be incorporated in an interface if such aid is to be given; to describe some of the solutions that have been implemented in experimental and operational interfaces; and to discuss some of the problems encountered. The paper closes with an extensive bibliography of references relevant to online search aids, going well beyond the items explicitly mentioned in the text. An index to software appears after the bibliography at the end of the paper.

The initial shock of devaluing the currency, after so many promises that it would not take place, has passed; only the uncertainty and apprehension remain. It seems an idle exercise to compare the present state of the country's economy with other periods in recent history, such as when in the first Labour Government, we went off the gold standard; at that time, shock was indeed profound and again, the French were cock‐a‐hoop, but the position was complicated by the huge inter‐indebtedness of the Allies in the First War. Or the first devaluation after the Second World War, but both periods were also characterized by public waste and profligate spending. Now, we have to obtain foreign loans and financial backing to keep going, and it is this aspect of the present devaluation which will probably far outweigh any positive advantages. The country's massive external debts were increased by approximately one‐seventh overnight, probably wiping out completely all the repayments made at such great effort since the War. Devaluation of the currency cannot be seen as anything but a grievous blow to the country, presaging hard times ahead for everyone. When promises were being made that devaluation would not take place, there can be little doubt that these were honestly made and, at the time, believed in, for no Government of a country with imports always exceeding exports, would impose such a burden on its people willingly. It must then have been forced upon them.

This paper examines the implications of the disability rights critique of prenatal testing on the development of genetic policy and abortion rights. It traces the reappearance of the disabled body in public deliberations over reproductive and genetic politics that use disability to frame arguments about which bodies are worthy of protection, how and why we limit reproductive choices, and what reasons women may use to terminate their pregnancies. The disability critique of prenatal testing and selective abortion finds itself in productive tension with reproductive rights politics, which increasingly features disability in both pro-life and pro-choice messages. The uneasy alliance between disability and pro-life interests has profound implications for both disability legal scholarship and the sociolegal inquiry into the role of rights articulation – and rejection – by social movements.

A report of exhibits at the Robot and Automation Show held at the NEC, Birmingham at the time of the 25th ISR. It highlights some of the new developments and products on show, leading with the description of a novel robot tube bender being exhibited for the first time. New products range from a 350kg capacity robot developed by Kuka to a high speed SCARA robot from Epson aimed at PCB odd form component placement applications currently dominated by Cartesian robots. Exhibits of software products emphasised the move to low cost PC‐based systems aimed at small robot users and systems integrators without the resources of large IT departments, notably from Deneb and BYG Systems.

This selective annotated bibliography presents a snapshot of research published between 1990 and 1999 that has studied negative political advertising, primarily in the USA. Political scientists, psychologists, communication theorists and marketing scholars have used experiments, surveys, and case studies to examine the impact of this type of advertising on voter beliefs and behavior. The author categorizes the literature by broad themes such as typologies, effects of negative ads, media coverage of political campaigns, and actual candidate behavior, and provides descriptive annotations of representative articles in each category. In addition, several scholarly books that discuss negative political advertising are annotated. Since the focus of this bibliography is on social science research, articles from the popular literature are not included.

SINCE the year 1940, there have appeared two major reports on the Public Library system in Great Britain. The first, “The public library system of Great Britain: a report on its present condition, with proposals for post‐war re‐organisation” by Lionel R. McColvin, appeared in 1942. It suggested sweeping changes in the organisation of the public library system, more radical and far‐reaching than those embodied in the recent recommendations of the Library Association for local government reform. On library co‐operation, the report was equally radical, though certain similarities with the recommendations of the second report are apparent.
