Abstract
This article describes the current status of the Success Likelihood Index Method (SLIM) approach to the quantification of human reliability in risk and reliability assessment. The technique has now been implemented using an interactive computer program called MAUD to give a stand‐alone package (SLIM‐MAUD) which can be easily used by engineers without specialist knowledge of human reliability assessment. The article describes the use of the technique to provide design recommendations. The application of SLIM‐MAUD to a series of nuclear power plant tasks is described.

Abstract
Before attempting to decide what are and what are not legitimate constituents of toilet and domestic soaps, it is necessary first to touch upon another question to which in some way it is more difficult to give a definite and satisfactory reply—namely, to what is the cleansing power of soap due? The answer to this depends a good deal upon the standpoint from which the matter is viewed. To the chemist the exact explanation is hardly yet entirely forthcoming, and he can at present only answer in a general way by saying that the chief value of a soap is owing to its power of dissolving or emulsifying fats; but why it does so is still more or less under discussion. It has been shown that a solution of a neutral soap when largely diluted with water is decomposed into free alkali, and a fatty acid which is precipitated.

Abstract
The concept of company culture is now playing an ever‐increasing role in the continuing endeavour to work towards ever better company management, particularly in the industrial field. This monograph reviews the history and development of both national and company cultures, and then goes on to demonstrate the significance of a culture to proper company management. Well‐managed companies will have both a “quality culture” and a “safety culture” as well as a cultural history. However, it has to be recognised that the company culture is subject to change, and effecting this can be very difficult. Of the many national cultures, that of Japan is considered to be the most effective, as is demonstrated by the present dominance of Japan on the industrial scene. Many industrialised nations now seek to emulate the Japanese style of management, but it is not possible to copy or acquire Japan′s cultural heritage. The text is illustrated by a large number of practical examples from real life, illustrating the way in which the company culture works and can be used by management to improve company performance.

Abstract
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.

Abstract
In years past, when life seemed simpler and the Law much less complicated, jurists were fond of quoting the age‐old saying: “All men are equal before the Law.” It was never completely true; there were important exemptions when strict legal enforcement would have been against the public interests. A classic example was Crown immunity, evolved from the historical principle that “The King can do no wrong”. With the growth of government, the multiplicity of government agencies and the enormous amount of secondary legislation, the statutes being merely enabling Acts, this immunity revealed itself as being used largely against public interests. Statutory instruments were being drafted within Ministerial departments largely by as many as 300 officers of those departments authorized to sign such measures, affecting the rights of the people without any real Parliamentary control. Those who suffered and lost in their enforcement had no remedy; Crown immunity protected all those acting as servants of the Crown and the principle came to be an officials' charter with no connection whatever with the Crown. Parliament, custodian of the national conscience, removed much of this socially unacceptable privilege in the Crown Proceedings Act, 1947, which enabled injured parties within limit to sue central departments and their officers. The more recent system of Commissioners—Parliamentary, Local Authority, Health Service—with power to enquire into allegations of injustice, maladministration, malpractice to individuals extra‐legally, has extended the rights of the suffering citizen.

Abstract
In a recent article dealing with the crimes against humanity committed by Germany, The Daily Telegraph remarks that thousands of innocent men, women, and little children murdered in cold blood by airship and submarine appeal for vengeance. The acts of Germany from the early days of the war onwards have filled decent‐minded people with feelings of loathing, and it is well that the last bonds uniting the two nations should be severed. This is no ordinary war. It has cut a deep chasm between the British and German peoples. By every means in our power we must remove, root and branch, those enemy influences in our midst which, by a process of “peaceful penetration,” were undermining our social, financial, and industrial power.

Abstract
The Food and Drugs Bill introduced by the Government affords an excellent illustration of the fact that repressive legislative enactments in regard to adulteration must always be of such a nature that, while they give a certain degree and a certain kind of protection to the public, they can never be expected to supply a sufficiently real and effective insurance against adulteration and against the palming off of inferior goods, nor an adequate and satisfactory protection to the producer and vendor of superior articles. In this country, at any rate, legislation on the adulteration question has always been, and probably will always be of a somewhat weak and patchy character, with the defects inevitably resulting from more or less futile attempts to conciliate a variety of conflicting interests. The Bill as it stands, for instance, fails to deal in any way satisfactorily with the subject of preservatives, and, if passed in its present form, will give the force of law to the standards of Somerset House—standards which must of necessity be low and the general acceptance of which must tend to reduce the quality of foods and drugs to the same dead‐level of extreme inferiority. The ludicrous laissez faire report of the Beer Materials Committee—whose authors see no reason to interfere with the unrestricted sale of the products of the “ free mash tun,” or, more properly speaking, of the free adulteration tun—affords a further instance of what is to be expected at present and for many years to come as the result of governmental travail and official meditations. Public feeling is developing in reference to these matters. There is a growing demand for some system of effective insurance, official or non‐official, based on common‐sense and common honesty ; and it is on account of the plain necessity that the quibbles and futilities attaching to repressive legislation shall by some means be brushed aside that we have come to believe in the power and the value of the system of Control, and that we advocate its general acceptance. The attitude and the policy of the INTERNATIONAL COMMISSION ON ADULTERATION, of the BRITISH FOOD JOURNAL, and of the BRITISH ANALYTICAL CONTROL, are in all respects identical with regard to adulteration questions; and in answer to the observations and suggestions which have been put forward since the introduction of the Control System in England, it may be well once more to state that nothing will meet with the approbation or support of the Control which is not pure, genuine, and good in the strictest sense of these terms. Those applicants and critics whom it may concern may with advantage take notice of the fact that under no circumstances will approval be given to such articles as substitute beers, separated milks, coppered vegetables, dyed sugars, foods treated with chemical preservatives, or, in fact, to any food or drug which cannot be regarded as in every respect free from any adulterant, and free from any suspicion of sophistication or inferiority. The supply of such articles as those referred to, which is left more or less unfettered by the cumbrous machinery of the law, as well as the sale of those adulterated goods with which the law can more easily deal, can only be adequately held in check by the application of a strong system of Control to justify approbation, providing, as this does, the only effective form of insurance which up to the present has been devised.

Abstract
The Food Bill has emerged from the Grand Committee on Trade, and will shortly be submitted, as amended, to the House of Commons. Whatever further amendments may be introduced, the Bill, when passed into law, will but afford one more example of the impotence of repressive legislation in regard to the production and distribution of adulterated and inferior products. We do not say that the making of such laws and their enforcement are not of the highest importance in the interests of the community; their administration—feeble and inadequate as it must necessarily be—produces a valuable deterrent effect, and tends to educate public opinion and to improve commercial morality. But we say that by the very nature of those laws their working can result only in the exposure of a small portion of that which is bad without affording any indications as to that which is good, and that it is by the Control System alone that the problem can be solved. This fact has been recognised abroad, and is rapidly being recognised here. The system of Permanent Analytical Control was under discussion at the International Congress of Applied Chemistry, held at Brussels in 1894, and at the International Congress of Hygiene at Budapest in 1895, and the facts and explanations put forward have resulted in the introduction of the system into various countries. The establishment of this system in any country must be regarded as the most practical and effective method of ensuring the supply of good and genuine articles, and affords the only means through which public confidence can be ensured.

Abstract
The great difficulties which attach to the fixing of legal standards of composition for food products have now to be grappled with by the Departmental Committee appointed by the Board of Agriculture to consider and determine what regulations should be made by the Board, under Section 4 of the Sale of Food and Drugs Act, 1899, with respect to the composition of butter. As we predicted in regard to the labours of the Milk and Cream Standards Committee, so we predict now that the Butter Committee will be unable to do more than to recommend standards and limits, which, while they will make for the protection of the public against the sale of grossly adulterated articles, will certainly not in any way insure the sale of butter of really satisfactory, or even of fair, composition. Standards and limits established by law for the purposes of the administration of criminal Acts of Parliament must of necessity be such as to legalise the sale of products of a most inferior character, to which the term “genuine” may still by law be applied as well as to legalise the sale of adulterated and sophisticated products so prepared as to come within the four corners of the law. It is, of course, an obvious necessity that official standards and limits should be established, and the Board of Agriculture are to be congratulated upon the manner in which they are endeavouring to deal with these extremely knotty problems; but it is important that misconception on the part of the public and the trade with respect to the effect of the regulations to be made should be as far as possible prevented. All that can be hoped for is that the conclusions at which the Committee may find themselves compelled to arrive will not be such as to place too high and too obvious a premium upon the sale of those inferior and scientifically‐adulterated products which are placed in such enormous quantities on the food market.

Abstract
The March issue of the Journal of Chemical Technology contains the following article, with every word of which we cordially agree. It is gratifying to find that there is one—if only one—of our scientific Journals which has the courage and the patriotism to speak out and to do so in vigorous terms. The indictment of the flabby persons belonging to the Chemical Profession who by their ineptitude and inertia are condoning the bestial crimes of the modern Huns is well‐timed and thoroughly deserved.
