In the first part of the paper, which outlines the laboratory and field investigations on corrosion by flue gases from solid fuel combustion carried out by the British Coal Utilisation Research Association, the effects of different flue gas constituents on corrosion phenomena are discussed. Laboratory studies of the effects of fuel type and method of combustion on the sulphuric acid content of combustion gases are described. The second part presents the results of measurements of the condensation characteristics of flue gases from water‐tube boilers in power stations and from various industrial boilers and furnaces; investigations into the use of additives are described briefly. The final section is concerned with some theoretical considerations of effects of fuel type, burning rate, etc., on the amounts of sulphuric acid likely to be present in the combustion products from domestic appliances.

In this, the concluding part of Mr. Kear's paper, methods of reducing corrosion by flue‐gas condensates are discussed, including fuel selection, the addition of ‘inerts,’ dusts and smokes. But it is the removal of the root causes of low‐temperature corrosion which is the preferred method.

The phenomenon of corrosion is so extensive that it is universally accepted as an inherent part of our present‐day commercial and industrial life. It is not surprising, therefore, to find corrosion problems associated with the most important of our chemical processes, the combustion of fuels. All our industrial fuels contain inorganic constituents, and during the combustion process certain of the more volatile constituents may be released in an active form to contaminate the combustion products.

It is rarely the case that a broader consideration of the available strategies for changing organisations is linked with empirical evidence on the way organisational change occurs. The purpose of this article is to examine data on the OD consultant's role as currently performed and the way consultants facilitate change. However, the intention is to broaden the discussion by setting this specific data against a backcloth of the current strategies for implementing organisational change. By examining the OD consultant's role against the wider perspective, the content, strengths and weaknesses of the role and of OD may be better understood.

“BEFORE the leaves of Autumn fall” we were assured by Mr. Churchill that there might be heavy fighting. They have not fallen yet, although with September, beautiful as it often is, we know the Summer is over and our minds must be occupied most immediately with the war. Libraries may seem to some, even librarians, secondary in this maelstrom but, even if they are, that secondariness is really so important that at this month everyone looks to his own work to see in what ways it may be geared up more fully for its own special contribution. Immediate planning concerns such matters as winter service hours, staffing, the growing wear and tear on stocks, the inadequacy of new book supply, the growing shabbiness of our buildings and our continuing inability to carry on the extension work which was so prominent a feature of many libraries. Frankly, in most towns we are giving a book service, not doing the library work, personal and bibliographical, which every librarian desires to give. To do what is within our limits to the best advantage is, then, the immediate problem.

The question of health and safety at work is a central issue for trade unions. In Britain it is an area of concern where there were important legislative initiatives in the 1970s and 1980s, although surprisingly this has received relatively little attention in the debates about trade unionism. This neglect results in an aspect of union activity about which little is known. Explores through a detailed longitudinal study of a middle‐range engineering firm, from the late 1970s into the 1990s, the ways in which trade unions organize and act on health and safety questions. Argues that it is almost “routine” that workers face dangers and hazards at work, a central feature of the work and employment experience of most workers. However, this is often difficult to deal with as individual issues, or as matters which are subject to collective consideration. On the one hand, workers often appear to accept the dangers and hazards they face. On the other hand, managements are preoccupied with questions relating to production and finance, rather than the day‐to‐day problems faced by workers. This tension suggests that the future wellbeing of workers in unionized workplaces lies not so much with legislative provisions and rights at work, but in education and the organizing ability of workplace unions, raising and addressing what often seem like individualistic problems in collective ways.

THE policy and organization of the Avro Repair Group was based upon intelligent anticipation—anticipation of the many and varied types of damage that might be expectedl anticipation of quantities, and anticipation of facilities to deal with all contingencies. The central depot at Bracebridge Heath, Lincoln, developed from an ex‐1914–18 war hangar to an establishment employing nearly 3,000 men and forming the hub of an organization that embraced many stations and subcontractors' works, civilian out‐working parties, of A. V. Roe personnel, effected a high proportion of major repairs to Lancaster, York and Anson aircraft; such parties were stationed all over the British Isles and were supplemented by a fleet of some seventy mobile workshops.

In advanced societies, lifestyles are increasingly sedentary, and it is important to identify strategies to help people acquire healthy habits, such as exercise. The present study proposes the use of gamification as a strategy for encouraging users to exercise regularly, based on the possibilities offered by “smart” devices such as smartbands.

The work analyzes how individuals experience their participation in a gamification program, on the premise that it should provide an experience that is intrinsically motivating and fun. Also the moderator effect of the gender and age on the relationship between their experience of participating in a gamification program and perceived self-efficacy.

The results show that individuals' experience of participating in a gamification program exerts a positive influence on their perceived self-efficacy in the practice of sport or exercise. The study also finds that the variables “gender” and “age” moderate the relationship between their experience of participating in a gamification program and perceived self-efficacy, such that it exerts a greater influence on women and older people.

The practical implications for the professionals and institutions involved in promoting the adoption of regular sport and exercise in society are about taking advantage of the potential of wearable technology such as smartbands. The present study finds that the use of gamification for encouraging people to adopt regular physical activity is more effective for women than for men, and for older people than for younger users.

The findings of this study provide a better understanding of whether gamification is an appropriate strategy for helping participants to perceive themselves as having greater self-efficacy in their chosen sport or exercise, taking into account the moderating effect of participant gender and age.

THE medical problems of flying were first seriously tackled during the latter part of the first world war, when it became obvious that mechanical construction was indivisible with pilot performance. Research has since proceeded along two main lines: pre‐selection of personnel for flying duties and the maintenance of the physiological efficiency of flying personnel. There is no doubt that the work accomplished is proving invaluable in these times of extended air force expansion and added interest is therefore given to the report of the symposium held at Washington D.C., at which Air‐Commodore H. E. Whittingham represented Great Britain.

This study (1) explores what programmes police services promote for autistic individuals on their websites and (2) describes how autistic individuals are constructed in the information about these programmes.

All 53 official police service websites in Ontario, Canada, were examined to determine which programmes were promoted for autistic individuals. Inductive qualitative content analysis was used to identify and describe how autism was constructed in the information about the programmes.

About 64.8% of police services in Ontario, Canada, promoted at least one programme to autistic individuals and their caregivers. These programmes included Vulnerable Person and Autism Registries, MedicAlert™ and Project Lifesaver™. Autistic individuals were described as vulnerable using medicalised and tragic narratives of autism.

Autistic individuals and caregivers have suggested several interventions to improve police-autistic individual encounters. Little is known about which interventions police services have adopted and which representations of autism are used to describe autistic individuals.
