In the year 1900 Koch expressed the view that human and bovine tuberculosis were distinct diseases, that the bacillus of bovine tuberculosis could not produce this disease in the human subject, and that the bacillus of human tuberculosis could not set it up in the bovine species. As is now well known. these conclusions have not received the slightest confirmation from other workers in the same field, and it may be said that the consensus of scientific opinion is now to the effect that the bacilli of human and bovine tuberculosis are identical—at any rate, so far as the effects attributed to them are concerned. The Royal Commission appointed in 1901, and consisting of the late Sir MICHAEL FOSTER, Drs. SIMS WOODHEAD, SIDNEY MARTIN, MACFADYEAN, and BOYCE, have issued a further interim report on their investigations. The first interim report was published in 1904, the conclusions stated in it being to the effect that the human and animal diseases were identical, and that no characteristics by which the one could be distinguished from the other had been discovered. The report now issued shows that these conclusions are confirmed by the results of a very large number of fresh experiments. The main conclusions set forth in the present report are as understated :—

Most decision-making problems in construction are complex and difficult to solve, as they involve multiple criteria and multiple decision makers in addition to subjective uncertainties, imprecisions and vagueness surrounding the decision-making process. In many instances, the decision-making process is based on linguistic terms rather than numerical values. Hence, structured fuzzy consensus-reaching processes and fuzzy aggregation methods are instrumental in multi-criteria group decision-making (MCGDM) problems for capturing the point of view of a group of experts. This chapter outlines different fuzzy consensus-reaching processes and fuzzy aggregation methods. It presents the background of the basic theory and formulation of these processes and methods, as well as numerical examples that illustrate their theory and formulation. Application areas of fuzzy consensus reaching and fuzzy aggregation in the construction domain are identified, and an overview of previously developed frameworks for fuzzy consensus reaching and fuzzy aggregation is provided. Finally, areas for future work are presented that highlight emerging trends and the imminent needs of fuzzy consensus reaching and fuzzy aggregation in the construction domain.

With numerous and ambiguous sets of information and often conflicting requirements, construction management is a complex process involving much uncertainty. Decision makers may be challenged with satisfying multiple criteria using vague information. Fuzzy multi-criteria decision-making (FMCDM) provides an innovative approach for addressing complex problems featuring diverse decision makers’ interests, conflicting objectives and numerous but uncertain bits of information. FMCDM has therefore been widely applied in construction management. With the increase in information complexity, extensions of fuzzy set (FS) theory have been generated and adopted to improve its capacity to address this complexity. Examples include hesitant FSs (HFSs), intuitionistic FSs (IFSs) and type-2 FSs (T2FSs). This chapter introduces commonly used FMCDM methods, examines their applications in construction management and discusses trends in future research and application. The chapter first introduces the MCDM process as well as FS theory and its three main extensions, namely, HFSs, IFSs and T2FSs. The chapter then explores the linkage between FS theory and its extensions and MCDM approaches. In total, 17 FMCDM methods are reviewed and two FMCDM methods (i.e. T2FS-TOPSIS and T2FS-PROMETHEE) are further improved based on the literature. These 19 FMCDM methods with their corresponding applications in construction management are discussed in a systematic manner. This review and development of FS theory and its extensions should help both researchers and practitioners better understand and handle information uncertainty in complex decision problems.

NOW that it is generally acknowledged that open‐access has come to stay, the attention of Public Librarians is becoming directed more to matters of detail in management, and less to the broader questions of policy. So far, however, the larger details, such as planning and interior arrangement, classification, and methods of issue—to name a few—have received most consideration, and there are many points of great importance to the practical utility of the library which yet remain to be dealt with systematically. It is on one of these points, the provision of Guides, that I propose to touch.

THE following list of contracts placed by the Air Ministry during October is extracted from the November issue of The Ministry of Labour Gazette:

THIS month is that in which librarians of public libraries are concerned with budgets. In spite of occasional croakings, it is fair to say that the worst of the crisis is over, and, if prosperity is not here, it is at least on the way. It will be interesting to learn if the cuts which some libraries had to make in their appropriations will be continued this year. Libraries have demonstrated beyond disproof that they have played a part in the depression in raising some of the gloom from the minds of the people, and can make reasonable claim to have financial consideration of the fact. Fortunately, in our worst times, the grotesque cutting which public libraries in the United States were called to endure was not suffered here.

In the very able and striking address which he recently delivered before the Society of Arts, Sir WILLIAM PREECE insisted that commercial success—whether of a man, of a body of men, or of a nation—is referable to the working of distinct laws, the recognition and study of which may justly be said to constitute a “science of business.” In terms rendered the more severe by their dispassionate and moderate character, Sir WILLIAM referred to the lamentable ignorance displayed by the legislature, by the manufacturer, and by the general public, of what may bo regarded as the most elementary facts and methods upon which such a science must be based. He pointed to the loose and bungling character of our commercial legislation; to the lack of co‐operation and combination; to the nonexistence of a properly organised and effective consular service whereby full information could be supplied and the interests of British trade, both home and colonial, might be studied and advanced; and finally to the lethargy of British producers and manufacturers themselves, who allow foreign competitors to drive them out of even their own home markets without making an effort to discard the old‐fashioned and worn‐out methods which have given those competitors the advantage. Of late years the warning voice has been raised from time to time, but it has been as a voice crying in the wilderness. The remarkable speech delivered at the Guildhall by H.R.H. THE PRINCE OF WALES is fresh in the recollection of those who are not too drowsy or too indifferent to appreciate the vital nature and the magnitude of the evil. In 1891 Lord PLAYFAIR stated that if the Americans were right in principle in the management of some of their commercial concerns, “the whole policy of the United Kingdom was founded on a gigantic error, and must lead to our ruin as a commercial nation.” Sir WILLIAM PREECE is amply justified in attaching severe blame to the British manufacturer and producer. They have allowed “the Americans and the Germans to oust them out of their own markets, not by any superiority in the quality of their goods, but by lower prices, by superior knowledge of the demands of the markets, by the establishment of new markets, by better direct communication with foreign countries, by superior methods in business ways, by establishing regular intelligence departments, and, above all, by possessing and exercising superior commercial technical knowledge,” “and,” continued Sir.WILLIAM, “they must lay aside the commercial habits of their fathers.” With regard to food‐products, for instance, can it be truly said that any adequate steps are taken to secure any satisfactory and permanent improvement of the national food supply with respect to purity and good quality? Has anything been done, with governmental or legislative assistance, to make a systematic study of, and provide authoritative information upon such questions as the sources from which food stuffs are obtained, the adequacy or inadequacy of supplies, the true value of home‐produce and the advantages of utilising colonial products as far as possible? The answers to these questions can only be emphatically in the negative. There is no civilised country in the world in which the producer and vendor of adulterated, impoverished, and inferior articles of food can cany on their nefarious practices with more impunity, in certain respects, than in the United Kingdom, although, originally, we led the way in framing legislative enactments on these all‐important matters. At every port of entry today we might most appropriately set up the old waste‐land notice that “rubbish may be shot here.” As we offer all the necessary facilities, and as they are being taken advantage of more and more, wo might also freely advise that “rubbish should bo manufactured here” as well, What steps do British producers and manufacturers of articles of food take to move with the times, to set their houses in order, to protect themselves, and to enable the public to differentiate between the good and the bad? In the vast majority of instances the attitude they adopt is still one of unmasterly inactivity, except in the direction of unscientific and clumsy advertisement. On this they spend enormous sums without proportionate returns, and in following this course they constantly lay themselves open to condemnatory criticism by the publication of unauthorised and exaggerated statements which, in spit© of CARLYLE'S dictum “mostly fools,” are now merely received by the general public with a shrug of the shoulders. The time has come when, in order not only to develop their trade but in order to keep it, British manufacturers must give evidence of an independent and authoritative character to justify the faith that is presumably in them in recommending their goods to the public. Those who refuse to entertain new ideas and who are content to rest in a semi‐comatose condition on the achievements of the past,—relying merely on the possession of the hitherto reputable “name of the firm,”—by the operation of an inexorable law must inevitably drop out of the race.

Reports received from all quarters indicate much movement in library affairs, partly as a result of the approach made to municipalities by the Library Association, partly because of the agitation initiated by Walthamstow, which we record in part elsewhere. The difficulties of the political and industrial situation do not seem to make a satisfactory milieu for an improved library situation, but, nevertheless, some of the most successful ventures of the past have seemed to be forlorn hopes. It is so now; the overwhelming weight of public opinion is clearly in favour of removing the disabilities from which libraries suffer. The questions asked and answered in the House of Commons recently show that the Local Government Board is not well posted as regards the position of opinion; but the Library Association is now in a position to relieve that august body from the difficulties of ignorance.

The decade of the 1980s was unique for the sheer quantity of education reform reports and legislation. Virtually every state enacted education reform legislation, including reforms of teacher education, licensing, and comprehension. According to Darling‐Hammond and Berry, over 1,000 pieces of legislation related to teachers have been drafted since 1980, and “a substantial fraction have been implemented.” As I discussed in my 1989 RSR article, “Five Years after A Nation at Risk: An Annotated Bibliography,” two waves of 1980s reform reports were identified in the enormous body of primary and secondary literature dealing with education reform. The reform publications of the early 1980s stressed improvements in curricular standards, student performance outcomes, and changes to the education programs, such as salary increases, teacher testing, and stricter certification requirements. The second‐wave reform publications emphasized more complex issues centered around the concepts of restructuring the schools and teacher education programs, as well as empowering teachers to become more involved in curriculum and governance issues.

Type-2 fuzzy sets became attractive in practice because of their footprint of uncertainty that gives them more degrees of freedom. This paper aims to use genetic algorithms (GAs) to design an interval Type-2 fuzzy logic system (IT2FLS) for the purpose of predicting bankruptcy.

The shape of type-2 membership functions, the parameters giving their spread and location in the fuzzy partitions and the set of fuzzy rules are evolved at the same time by encoding all together into the chromosome representation. The enhanced Karnik–Mendel algorithms are used for the centroid type-reduction and defuzzification stage. The performance in predicting bankruptcy is evaluated by benchmarking IT2FLSs against type-1 FLSs. The experimental setup consists of evolving 100 configurations for both the T1FLS and IT2FLS and comparing their in-sample and out-of-sample average accuracy.

The experiments confirm that representing and capturing uncertainty with more degrees of freedom is an important advantage. It is this extra potential of IT2FLSs that allows them to outperform T1FLS, especially in terms of generalization capability.

The strategy followed in this paper is to train an IT2FLS from scratch rather than tuning the parameters of an existing T1FLS. Because this leads to solving a mixed integer optimization problem, the GA-based approach is specifically designed and uses genetic operators that are most suited for such a case: tournament selection, extended Laplace crossover and power mutation. Finally, the trained IT2FLS is applied to bankruptcy prediction, and its generalization capability is compared with related techniques.
