Prostate and colorectal cancer (CRC) rates are disproportionately high among African‐American men. The purpose of this paper is to describe the development of an intervention in which barbers were trained to educate clients about early detection for prostate and CRC.

Working with an advisory panel of local barbers, cancer survivors and clients, educational materials are developed and pilot tested through use of focus groups and cognitive response interviews.

The advisory panel, focus groups, and interviews provide key recommendations for core content, intervention structure, and evaluation strategies. The men suggest a variety of things they want to know about prostate cancer, however the perceived need for CRC information is much broader, suggesting a knowledge gap. The men prefer print materials that are brief, use graphics of real African‐American men, and provide a telephone number they can call for additional information.

Community involvement is key in developing a well‐accepted and culturally‐relevant intervention.

The paper usefully describes the process of developing and pilot testing educational materials for use in an intervention in which barbers would be trained as community health advisors, to educate their clients about CRC screening and informed decision making for prostate cancer screening.

Our article in last month's Library World has elicited some expressions of opinion from various sources, which we print as a contribution towards a general discussion of this important question. It, will be observed that several writers have not quite grasped the exact scope of our proposal, which was not an argument in favour of an increase of the Library Rate by Act of Parliament, but a plea for leaving the amount of the Rate entirely in the hands of the local authorities. This is a very different thing from asking Parliament to raise the amount of Rate all round from one penny to two pence or more per £. If local authorities can be trusted to levy the huge sums required under the various Sanitary, Police and Poor Laws, surely they can be trusted to ascertain the comparatively small needs of a Public Library, and make a Rate in accordance with local requirements. It is impossible to imagine that in any case this power would be abused. As a rule, rating bodies are extremely scrupulous and fearful about raising rates, and this fear and public spirit could be trusted to keep in cheek any tendency towards extravagance. Besides, it must be obvious to every observer that the needs of Public Libraries are not such as to call for lavish expenditure. At the same time, why should a town desirous of extending and improving its library system be debarred from doing so, because of an Act passed nearly fifty years ago, when educational legislation was only in an experimental stage? The more discussion and argument we can have on this subject, the quicker are we likely to arrive at a definite basis of agreement, and we therefore print the following opinions as an introduction to a general discussion.

We study the relationship between underwriter prestige, family control, and IPO underpricing in an international setting. Data are collected for 5,789 firms that went public across twenty‐five countries between 1995 and 2002. We find that non‐penny‐stock and non‐U.S. IPOs from countries where firms are predominately family‐controlled benefit from associations with well‐known investment bankers; i.e., these firms are less underpriced than similar firms from countries with a low level of family control. At the same time, our findings support prior evidence that suggests that underwriter prestige is positively related to underpricing in the U.S. IPO market. Family‐controlled firms should consider the findings of this study, which identifies factors that are associated with more successful IPO outcomes.

The news that the Ministry of Education has set up two Working Parties in connection with the proposed new Public Libraries Bill is welcome and gives further hope that such a Bill will appear in the not too distant future. From the constitutions of these Working Parties, which seem to us to be fairly representative of all interests, it would appear that the first is going to concern itself with the main aspects of the Roberts Report recommendations, while the second will be given the task of studying the problems of library co‐operation. On the first party, county libraries are represented by Miss Paulin and Mr. Budge, while Wales is represented by Mr. A. Edwards, librarian of the Cardiganshire and Aberystwyth Joint Library. Mr. D. I. Colley, the city librarian of Manchester, will be keeping a watching brief on behalf of the large libraries, but it should not be forgotten that he is also a member of the Libraries Committee of the Association of Municipal Corporations. Mr. Gardner is rightly there, perhaps not only as librarian of Luton but also as chairman of the Library Association's Executive Committee. The Smaller Libraries Group can surely have no complaints, for out of the ten members of Working Party No. I there are three librarians from smaller libraries, these being Mr. Helliwell of Winchester, Mr. Christopher of Penge and Mr. Parker of Ilkley. This Working Party is completed by two legal representatives in Mr. W. B. Murgatroyd, who is Town Clerk of Hornsey, and Mr. J. H. Oldham, who is Assistant County Solicitor for Kent.

The management of children′s literature is a search for value and suitability. Effective policies in library and educational work are based firmly on knowledge of materials, and on the bibliographical and critical frame within which the materials appear and might best be selected. Boundaries, like those between quality and popular books, and between children′s and adult materials, present important challenges for selection, and implicit in this process are professional acumen and judgement. Yet also there are attitudes and systems of values, which can powerfully influence selection on grounds of morality and good taste. To guard against undue subjectivity, the knowledge frame should acknowledge the relevance of social and experiential context for all reading materials, how readers think as well as how they read, and what explicit and implicit agendas the authors have. The good professional takes all these factors on board.

The year opens with omens good, and foreboding, for librarians. Of the first kind is the re‐opening after two years of the Science Museum at South Kensington. The second was the astounding proposal of the Air Ministry to commandeer the British Museum for its administrative work. After three years of a war which has shown the devastating results of the neglect of things educational and spiritual the rulers of this country had apparently acqui sced in a proposal which, in the words of the President of the British Association, would “cause a shudder to run through all civilised countries. Were it carried out it would cover the British nation with lasting obliquy.” As we go to press, however, it is announced that the proposed outrage is not considered to be necessary and will therefore not take place. We rejoice over the repentance of the Government; but the fact that the proposal was made seriously, and for a time upheld, is so significant that it behoves all who value the treasures of the nation to be upon their guard. The war, also, is not over yet.

The purpose of this paper is to provide a new computational method based on the polynomial chaos (PC) expansion to identify the uncertain parameters of load sensing proportional valve (LSPV), which is commonly used to improve the efficiency of brake system in heavy truck.

For this investigation, the mathematic model of LSPV is constructed in the form of state space equation. Then the estimation process is implemented relying on the experimental measurements. With the coefficients of the PC expansion obtained by the numerical implementation, the output observation function can be transformed into a linear and time-invariant form. The uncertain parameter recursively update functions based on Newton method can therefore be derived fit for computer calculation. To improve the estimation accuracy and stability, the Newton method is modified by employing the acceptance probability to escape from the local minima during the estimation process.

The accuracy and effectiveness of the proposed parameter estimation method are confirmed by model validation compared with other estimation methods. Meanwhile, the influence of measurement noise on the robustness of the estimation methods is taken into consideration, and it is shown that the estimation approach developed in this paper could achieve impressive stability without compromising the convergence speed and accuracy too much.

The model of LSPV is originally developed in this paper, and then the authors propose a novel effective strategy for recursively estimating uncertain parameters of complicate pneumatic system based on the PC theory.

A MIXED feeling seems to be present in the minds of members of Public Library Committees regarding the clause in the new Libraries Bill which gives local authorities the option of increasing the present limited rate of one penny to any amount up to a maximum total of twopence in the pound. In view of the fact that the extension of the rate can only be made at the discretion of local authorities, it is difficult to see what objections can be brought against it. One of the strongest arguments in favour of an extension of the penny rate limit is that about thirty library districts have varied the Acts by special legislation giving increased rating powers. When one realizes the demands made on Public Libraries at the present day, compared with those made upon them in 1855, when the penny rate was fixed, the suggested increase appears to be only reasonable.

Those who contemplate attending the Annual Conference of the Library Association at Portsmouth would be well advised to secure their accommodation immediately if they have not done so already. The demands upon hotel space have been very much greater than even sanguine members anticipated, and already we hear of people being refused rooms because they are no longer available. Portsmouth, of course, is the naval centre of the Empire, and that common‐place piece of knowledge is magnetic, nevertheless. There are other attractions in Portsmouth. Its situation, practically adjacent to the Isle of Wight, with all its charms, on one side, and its nearness to the New Forest and the belt of Hampshire towns on the west, and on the east with such places as Chichester, Selsey, Bognor, Worthing, and Brighton make it, from the location point of view, of special interest. There is the further call of the literary associations of Portsmouth. Every book on the Navy has something about it, as those of us who read W. H. G. Kingston, Captain Marryatt and many another sea‐author can testify. Perhaps the most important author who came out of Portsmouth was not a sea‐writer but the son of a naval outfitter—George Meredith. Pernaps to a post‐War generation he seems old‐fashioned, involved, unnecessarily intricate, precious, and possesses other faults. This is a superficial point of view, and certainly in his poems he rises to heights and reaches depths that are denied to most writers of to‐day. In any case, The Ordeal of Richard Feverel and Beauchamp's Career, to say nothing of The Egoist, are among the great novels of the English language.

The Sanitary Committee of a certain County Council, strong with the strength of recent creation, have lately been animated by a desire to distinguish themselves in some way, and, proceeding along the lines of least resistance, they appear to have selected the Public Analyst as the most suitable object for attack. The charge against this unfortunate official was not that he is incompetent, or that he had been in any way negligent of his duties as prescribed by Act of Parliament, but simply and solely that he has the temerity to reside in London, which city is distant by a certain number of miles from the much favoured district controlled by the County Council aforesaid. The committee were favoured in their deliberations by the assistance of no less an authority than the “Principal” of a local “Technical School”;—and who could be more capable than he to express an opinion upon so simple a matter? This eminent exponent of scientific truths, after due and proper consideration, is reported to have delivered himself of the opinion that “scientifically it would be desirable that the analyst should reside in the district, as the delay occasioned by the sending of samples of water to London is liable to produce a misleading effect upon an analysis.” Apparently appalled by the contemplation of such possibilities, and strengthened by another expression of opinion to the effect that there were as “good men” in the district as in London, the committee resolved to recommend the County Council to determine the existing arrangement with the Public Analyst, and to appoint a “local analyst for all purposes.” Thus, the only objection which could be urged to the employment of a Public Analyst resident in London was the ridiculous one that the composition of a sample of water was likely to seriously alter during the period of its transit to London, and this contention becomes still more absurd when it is remembered that the examination of water samples is no part of the official duty of a Public Analyst. The employment of local scientific talent may be very proper when the object to be attained is simply the more or less imperfect instruction of the rising generation in the rudiments of what passes in this country for “technical education”; but the work of the Public Analyst is serious and responsible, and cannot be lightly undertaken by every person who may be acquainted with some of the uses of a test‐tube. The worthy members of this committee may find to their cost, as other committees have found before them, that persons possessing the requisite knowledge and experience are not necessarily indigenous to their district. Supposing that the County Council adopts the recommendation, the aspirations of the committee may even then be strangled in their infancy, as the Local Government Board will want to know all about the matter, and the committee will have to give serious and valid reasons in support of their case.
