SEPTEMBER this year will be unique in the history of the librarian in England in that for the first time in nearly sixty years the annual conference of the Library Association has already become a memory only. There are those who profess to believe that the conference should be restored to the autumn months. It may be suggested on the other hand that the attendance at Margate lent no assistance to that point of view; indeed, the Margate conference was one of the most pleasant, one of the most successful, of which we have record. Nevertheless, if it can be proved that any large body of librarians was unable to be present owing to the change of month, it appears to us that the matter should be considered sympathetically. Although no one holds any longer the view that one week's attendance at a conference will teach more than many months' study in hermit‐like seclusion—the words and sentiments are those of James Duff Brown—because to‐day there is much more intimate communication between librarians than there was when that sentiment was expressed, there is enormous value, and the adjective is not an exaggeration, in one large meeting of librarians in body in the year. It is an event to which every young librarian looks forward as the privilege to be his when he reaches a high enough position in the service; attendance is a privilege that no librarian anywhere would forego. And this, in spite of the fact that there is usually a grumble because the day is so full of meetings that there is very little chance of such recreation as a seaside, or indeed any other, place visited, usually provides for the delegates.

Details a cross‐cultural study to expose the extent to which public concern regulates sexual‐eroticism and withdraws it from public attention; identifies a propensity towards the ideal of sexual constraint within US society, reflected by a high degree of regulation and criminalization of sexuality ‐ ranging from strict policies on sexual‐harassment to the restriction of explicit images, even for sex education purposes. Compares with the more liberal attitudes exhibited in Germany. Develops an empirical model to establish cultural differences in attitudes to sexual issues; confirms that Germans are less likely to stigmatize sexual eroticism than their American contemporaries. Concludes that Germans exhibit emotions that typify sexual emancipation, compared with the sexually constrained emotions of Americans; suggests a link between the repression of sexual emotions and violence in society.

Ministry of Health, Whitehall, S.W. 1. 12th June, 1924. SIR, I am directed by the Minister of Health to state that on consideration of communications received through the Foreign Office from the Government of the Latvian Republic, he has decided to recognise as an Official Certificate for the purposes of the Public Health (Foreign Meat) Regulations a label and mark issued by the Government of that country. He has accordingly caused to be published in the London Gazette of the 30th May, 1924, a Notice containing in the schedule a description of the label and mark which is declared to be admissible as an “Official Certificate” in respect of pork and other edible portions of the pig, which have been subjected to inspection in the Latvian Republic.

This paper aims to revisit the preventive maintenance scheduling literature. The problem to be solved is the simultaneous scheduling of resource‐constrained preventive maintenance and operations. In particular, the expression that defines the period‐dependent cost function for a preventive maintenance scheduling activity is redefined. A case study is presented from the shipping industry.

In this paper a mathematical theory of differential calculus known as three‐dimensional wave equation is applied. The methodology involves transforming the preventive maintenance cost function that is expressed in terms of several variables into a more precise framework. The motivation for the work is the need to measure the total preventive maintenance scheduling cost more precisely than with the use of the existing linear cost structure.

In this paper the findings from the analysis carried out found evidence that validates the claim of the feasibility of analyzing preventive maintenance cost using the approach proposed.

The paper shows that, in practice, maintenance managers strive to reduce the cost of preventive maintenance activities in order to achieve low cost production of goods. This would encourage a high patronage of customers and prevent decisions being made on wrong data. The approach presented here aims at correcting this weakness by revealing a more precise and reliable method of preventive maintenance scheduling cost computation. This is a scientific tool that should be of immense benefit to maintenance planners, particularly those actively engaged in scheduling functions.

The work in this paper is new, since a novel framework is presented in a way that has not been documented earlier.

What is the Purpose of the Library? The question is exercising not only the English librarian but his American colleague, and we notice that one of our contemporaries there has given some space to this fundamental question. The simple reply to the question would seem to be “To provide the community with the books it needs.” Such a reply, however, is likely to be regarded as an over‐simplification. Nevertheless, we may adhere to it because the operative word in our definition is “needs” and not “wants.” To discover the needs of a community, which are as manifold as there are people in it, is in itself a formidable task; to supply the books which are likely to satisfy them is a life‐work worthy of the ablest of men. These considerations should never be lost sight of in the attempts which occur from time to time to define a programme of library work. We are the last to believe that our province should be a limited one and we deprecate any attempt to thwart the enthusiasm of any librarian, young or old, who has something constructive to contribute. Our definition, however, is indisputable. The addition to it that the librarian makes was defined years ago in Brown's Manual, which declared his work to be the exploiting of books. A programme then, if there is to be one, is merely of the best methods of exploitation by good technique, tactful advertisement, and a personal service which radiates willingness. The librarian must always beware of the many attempts that are made to harness the library to particular movements, shibboleths or partisan‐ships: the so‐called programmes which endeavour to define a purpose for the library will often be found to be influenced by one of these three evils. The matter thus stated seems trite enough, but it would seem that there is necessity for its fequent re‐statement.

Among the many pressing social issues facing today's urban areas is how to provide adequate and efficient transportation facilities while maintaining a healthy economic and social environment. In light of this problem the federal government is spending billions of dollars in improving existing transit systems and in developing new ones in major cities across the United States. There is considerable debate over how this funding could best be utilized. During the past few years there has been an increasing amount of literature published by leading government, private, and academic research centers in the areas of transportation policy, economics, and technological innovations. Libraries, particularly public libraries in those cities directly affected by these new transit programs, are likely to face an increasing number of reference questions from citizens concerned with how these new systems will affect their lives and the life of their city.

It will be a momentous year, even if prophecies are not fulfilled in the sense in which they are so recklessly made. Threats of terrors at Christmas, especially for London, did not materialize. There are some readers who whisper that they do not believe in a Second Front at all. And so on: jade Rumour lies as earnestly today as ever in her unwholesome history. But much must happen before we can again utter the wish with which we begin. Our business, in addition to our imperative war duties, is to carry to conclusions of value the post‐war policies we have received from the Library Association. We have more than that to do. Some of our libraries, even those that have not suffered from direct bombing, are in a state which in peace conditions we should say was deplorable.

The purpose of this paper is to work on an analytical approach to test sensitivity of a maintenance‐scheduling model. Any model without sensitivity analysis is a “paper work” without advancing for wider applications. Thus, the simulation of simultaneous scheduling of maintenance and operation in a resource‐constrained environment is very important in quality problem and especially in maintenance.

The paper uses an existing model and presents a sensitivity analysis by utilising an optimal initial starting transportation tableau. This is used as input into the Gantt charting model employed in the traditional production scheduling system. The degree of responsiveness of the model parameters is tested.

The paper concludes that some of these parameters and variables are sensitive to changes in values while others are not.

The maintenance engineering community is exposed to various optimal models in the resource‐constraint‐based operational and maintenance arena. However, the models do lack the sensitivity analysis where the present authors have worked. The work seems significant since the parameters have the boundary values so the user knows where he can apply the model after considering the constraints therein.

The underlying quest for testing the sensitivity of the model parameters of a maintenance scheduling model in a multi‐variable operation and maintenance environment with resource constraints is a novel approach. An optimal solution has to be tested for robustness, considering the complexity of the variables and criteria. The objective to test the model parameters is a rather new approach in maintenance engineering discipline. The work hopefully opens a wide gate of research opportunity for members of the maintenance scheduling community.

The purpose of this paper is to identify the factors responsible for road traffic accidents among commercial commuter drivers in Lagos, Nigeria.

A total of 188 commercial drivers, driving 18‐seater mass transit buses in inter‐city highways were studied. Their accident records for the previous three years collected from Police records, Federal Road Safety Commission records, self‐administered questionnaires and observation of driving habits of the drivers. Their eye status were measured and data also collected from the Driver Union's Insurance Agency. A total of 25 human factor variables, identified as possible contributors to road traffic accidents were studied.

Six variables were found as possible significant contributors to road traffic accidents. They are old age, overtaking, overspeeding, religious affiliation, bad brake conditions and use of bad tyres. When the variables were subjected to two‐way interactions, 44 variable combinations were significant (p < 0.05) with R² of 0.994 and residual error of 1.165.

Accidents are not usually caused by single variables but by a combination of variables.

Apart from variables commonly found in the literature as possible causes of road traffic accidents, there may be some factors that may be peculiar to some countries like religious affiliation, belief in use of charms to protect drivers from accident and eye problems that are not identified because of lack of regular tests among others.

The simultaneous scheduling of resource‐constrained maintenance and operations is addressed in this work. The purpose of the paper is to capture the uncertainty in the development of a model that schedules both preventive maintenance and operational activities. Fuzzy logic is employed to transform the human expertise into IF‐THEN rules.

The approach has the advantage of revealing semantic uncertainty with the associated non‐specifying measures. The methodology applied tracks the error values in terms of results in linguistic variable.

The results obtained indicate the feasibility of tracking the uncertain measures in the model discussed. Thus, the study may be applicable to both production system and transportation organizations that are engaged in both maintenance and operational activities.

The research has serious implication in terms of the ability to monitor the imprecision that were introduced in the previous models. This obviously provides a more reliable framework for researchers and practitioners interested in maintenance scheduling activities.

The paper is new in that it demonstrates the application of fuzzy logic in a form that was never documented.
