EVERYONE interested in the British library movement will learn with sorrow and regret that one of its greatest friends and strongest champions has passed away, in the person of Thomas Greenwood, the kind‐hearted and generous advocate of libraries, who won the respect and regard of every English libiarian. From one of his own periodicals the following particulars are abstracted:—

To anyone concerned with the use of lubricants the word “additive” is nowadays commonplace, but just what an additive is or what is meant by additive treatment is not so widely understood. Any attempt at a simple explanation would undoubtedly err on the side of understatement and leave a lot unexplained but some form of definition is necessary as a basis from which to work.

In this series of articles, the author reviews some of the problems involved in the lubrication of modern automobiles and suggests how the use of additive treated oils can assist in their solution. This part reviews the fundamental points concerning automobile engine lubrication and part two will deal with Additives. Later parts will cover fuels, oil consumption and drain periods, transmission lubricants, chassis lubrication, etc.

Later parts will cover oil quality, specifications, transmission oils, upper cylinder lubricants, etc.

In this series of articles the author has revieiced some of the problems involved in the lubrication of modern automobiles and has suggested how the use of additive‐treated oils can assist in their solution. Previous parts appeared in the December, January, February and April issues.

This article looks at the attitudes and perceptions that young offenders have of dental health and services prior to and during their time at a Young Offenders’ Institution in the North East of England. The recent incorporation of prison health services into National Health Service (NHS) structures and funding arrangements brings with it statutory responsibilities concerning the amount and equivalence of health care in and out of prison settings. It also requires evaluation of services in comparable ways. Prison health in general and prison dental health in particular have previously been isolated from mainstream NHS health care in terms of both practice and research. The results from this study highlight the need for those responsible for dental health services at all penal institutions to examine the levels of provision they provide and how the perspectives of this marginalized and vulnerable group can be taken into account in the planning and improvement of services.

As increasing numbers of older people retain their teeth for longer, the result is a dramatic change in both the volume and type of dental treatment required. In response to the ageing population issues, changing dental needs, a shortage of NHS dentists, and the creation of new roles in the dental profession, both the UK Department of Health and British Dental Association have emphasised the importance of dental workforce planning and in particular to estimating the size and skill‐mix of the dental team. The dental team includes such professions as dentists, hygienists, therapists and technicians. The purpose of this paper is to present collaborative work between operational researchers and dental public health researchers, and as such is the first academic project to utilise operational research (OR) techniques to address issues surrounding predictions on demand and supply of dental activities in England, with recommendations on the necessary skill‐mix of the dental team.

A three‐stage model has been constructed to predict demand for dental treatment, dental workforce supply and optimisation of the skill‐mix of the dental workforce team over the next 20 years. A cost‐benefit study is included and Monte Carlo simulation is used for sensitivity analysis.

The findings reveal a significant shortage in dental workforce supply, both currently and projected for the short‐term future.

Demand for dental treatment is certain to rise over the next 20 or more years. An ageing population coupled with trends in increased tooth retention will have a significant impact on the need and demand for dental care amongst older people in the future. This research makes a series of recommendations in order to expand public care provision in a cost‐effective manner.

There is an urgent need to provide recommendations on the desirable skill‐mix of dental teams, and their cost‐effectiveness. This paper presents novel collaborative work between operational researchers and dental public health researchers, and as such is the first academic project to utilise OR techniques to address issues surrounding predictions on demand and supply of dental activities.
