The function of lead additives in petrol is described, together with the effects on various engine components of their removal. The corrosive wear mechanisms are described in detail, and the effect of alternative additives in reducing corrosion and wear are covered. A number of field case histories are described, including experiences in Sweden, where lead replacement petrol was introduced in 1992. The article concludes with a series of recommendations designed to minimise possible damage to engines caused by substitution of leaded petrol by LRP.

Against a background of rapidly developing technology and changing social attitudes, there are many different ways of regarding enquiry work. This article focuses on the problem of characterising information and enquiry work, how it relates to traditional reference work, and how it is adapting to the Internet. Issues of co‐operation and government policy are briefly considered.

A distinction must be drawn between a dismissal on the one hand, and on the other a repudiation of a contract of employment as a result of a breach of a fundamental term of that contract. When such a repudiation has been accepted by the innocent party then a termination of employment takes place. Such termination does not constitute dismissal (see London v. James Laidlaw & Sons Ltd (1974) IRLR 136 and Gannon v. J. C. Firth (1976) IRLR 415 EAT).

To achieve a full understanding of the role of marketing from plan to profit requires a knowledge of the basic building blocks. This textbook introduces the key concepts in the art or science of marketing to practising managers. Understanding your customers and consumers, the 4 Ps (Product, Place, Price and Promotion) provides the basic tools for effective marketing. Deploying your resources and informing your managerial decision making is dealt with in Unit VII introducing marketing intelligence, competition, budgeting and organisational issues. The logical conclusion of this effort is achieving sales and the particular techniques involved are explored in the final section.

Aims to: familiarize the audience with the potentially serious consequences of exposure to lead and ways of preventing them; facilitate understanding of how massive environmental contamination with lead occurred, and is still happening, with the expectation that this knowledge will be useful in designing strategies to reduce environmental contamination with lead and other toxic substances, in the future; emphasizes the relevance of lead to the subject‐matter of virtually every department in schools of arts and sciences in anticipation that some instructors will incorporate this information into their respective courses to increase their students′ awareness of this topic. Discusses some of the properties and uses of lead and its compounds and then indicates its ubiquitous presence in air, water, soil, dust and food. Considers some effects of exposure to lead and describes some pivotal contributions of various researchers. Explores the role of lead in history, in literature and in art. Briefly surveys occupational exposure to lead in the USA and elsewhere. Describes the reasons for, and consequences of, lead in petrol and in paint. Summarizes an outstanding paper on the topic of values and lead. Finally, based on an examination of a portion of the voluminous literature on lead, offers some opinions on this subject.

Properly conceived, conducted and interpreted, motivation research can be an extremely powerful management tool, designed to help the manufacturer or advertiser to sell more goods. Its aim is to expose the market situation, explain it and suggest courses of action which will lead to desired changes. It is a way of looking at a problem rather than a collection of specialist techniques and is strictly practical. Hence it can be used alongside other market research tools for the solution of marketing problems and can be applied to a wide range of business activities. Much of its development has been in the advertising field but it can also help in the formulation of production policy, solving packaging problems and marketing operations. It is examined here in all these contexts. The idea of motivation research, the reasons for its use and the techniques by which to apply it are discussed, as well as the pitfalls that are likely to occur. New and imaginary case studies are used throughout to illustrate points. A review of the subject literature is included.
