Abstract
THE Society of Automotive Engineers' paper, upon which this article is based, followed very closely along the lines of an article entitled ‘Composite Power Plant System for V/S.T.O.L. Aircraft’ published in the December, 1962, issue of AIRCRAFT ENGINEERING [see Ref. (4)]—although the latter paper concentrated upon a description of the RB. 162 and the use of lightweight lift engines for a V/S.T.O.L. low‐level strike fighter. The S.A.E. paper has therefore been slightly condensed here, to avoid unnecessary duplication and a number of illustrations have been omitted. Throughout this paper there are references to the advantages of a multi‐engined aircraft for the V/S.T.O.L. fighter application in preference to the single‐engined type. These passages must be read in the light of the recent statement to the effect that Rolls‐Royce have submitted to the Ministry of Aviation design proposals for a version of the Hawker PA 154 V.T.O.L. aircraft powered by two lift/thrust engines based upon the Spey by‐pass engine. These two lift (thrust engines would replace the single Bristol Siddeley BS.100 vectored thrust engine which is believed to have a thrust (with plenum chamber burning) of about 30,000 lb. Apart from the more obvious advantage of having two engines, i.e. safety, and the ability of the aircraft to complete the mission as a conventional aircraft if one engine fails, there is also the additional and attractive proposition that the Rolls‐Royce Spey engine is already in quantity production for a number of civil and military aircraft and could presumably be readily adapted to a lift/thrust configuration with front nozzle incorporating plenum chamber burning and rear nozzle. Finally, the reader is recommended to study in full the articles referred to in Refs. (2), (3), (4) and (5), in addition to this paper, since these provide a comprehensive survey of the jet lift field and in particular the application of jet lift to V/S.T.O.L. fighters. The six references listed on this page did not, of course, form part of the original S.A.E. paper—Editor.

Abstract
A Description of the Development of the Bristol Siddeley Pegasus and Plenum Chamber Burning for the BS.100 and an Outline of the Performance of a V/S.T.O.L Subsonic Strike Fighter Utilizing a Vectored Thrust Engine with PCB as Compared with a Composite Power Plant Fighter and a Vectored Thrust Type without PCB. The Bristol Siddeley Pegasus vectored‐thrust turbo‐Tan has now been in operation for six years, and during that time has been developed to a fully operational stan‐dard in the Hawker Siddeley Kestrel V/S.T.O.L. sub‐sonic strike fighter. Initial development of a second‐generation V/ S.T.O.L. strike fighter for supersonic flight necessitated thrust augmentation by combustion in the normally cold by‐pass flow. This gave rise to the design and development of a suitable combustion system, now known as ‘Plenum Chamber Burning’, or ‘PCB’. This paper summarizes the satisfactory development of the Pegasus vectored‐thrust turbofan, gives some description of the PCB system development, and shows how the application of this system to a V/S.T.O.L. subsonic strike fighter vectored‐thrust power plant gives the latter considerable superiority when compared with an equivalent composite power plant configuration.

Abstract
The Asia‐Pacific Region is the fastest growing area of the world in economic terms. Unfortunately, it has also suffered from several environmental and occupational health problems largely as a result of this rapid growth without attendant safeguards. Highlights problems such as environmental pollution, those relating to sanitation, cigarette smoking, traffic accidents, poisoning from industrial and agricultural chemicals, noise, health of women workers and other psychosocial problems, and recent trends in the health education and environmental improvements. Concludes with a plea for more attention to and collaboration concerning a clean environment.

Abstract
AIRCRAFT ENGINEERING was born in March 1929 of the belief that the emerging technology from which it took its title would become a fundamental element of engineering progress. The keystone of its policy was that it would attempt to meet the needs of engineers and students working in this field and that its contents should be ‘written by engineers — for engineers’. That this venture was fully justified has been amply vindicated by the achievements of the industry during the ensuing 41 years — as recorded in the first 500 issues of this Journal, the major milestone celebrated this month. This is a propitious occasion on which to review the record to date because, although aviation has always been about looking forward, history is instructive and it is the impressive performance of the aerospace industry to date that inspires and motivates confidence in its future.

Abstract
Describes the training model employed to train trainers for the UK‐based ATLS (Advanced Trauma Life Support) programme. A questionnaire evaluation of the course reveals the effectiveness of the training model when compared to other training provision in postgraduate medical education. The course is seen to be very effective in raising the confidence of instructors who have little previous training in instructional methods. Identifies and discusses the successful characteristics of the course which include a high tutor:student ratio, extensive use of interactive learning strategies, continuous assessment, a focus on problem‐based learning and the use of self and peer group critiquing strategies.

Abstract
Purpose
The hospitalist concept aims for integration and continuity of care in inpatient treatment. The purpose of this paper is to understand how the hospitalist function emerges and unfolds on wards. Therefore, the paper aims to focus on interaction patterns and the role of the hospitalist.
Design/methodology/approach
Building on methodological approaches in health care team research, this process‐oriented case study used participatory observations and semi‐structured interviews. Over a year, 14 observational days were conducted, simultaneously accompanying hospitalists, nurses and surgeons. Observational data illustrate the findings.
Findings
The hospitalist function was perceived to have a positive impact. He/she serves as an informal leader by taking up five interrelated, mostly coordinative roles, which help to cope with different organisational gaps. The interaction patterns are bilateral, ad hoc, reactive, repetitive and dependent on chance and people. Roles, tasks and responsibilities are continuously negotiated.
Research limitations/implications
Hospitalist research should make use of the debate in health care team research about overlapping roles, tasks and responsibilities. Additionally, one could look at the origins behind the evolvement of interaction patterns and the hospitalist's roles.
Practical implications
The sole creation of the hospitalist function is not sufficient to tap its full potential. Organisational issues concerning the interaction processes need to be addressed. In so doing, the professions' orientations must be taken into account.
Originality/value
This paper addresses theoretical and methodological gaps in hospitalist research. Using a process‐oriented qualitative design, the findings question the prominent stimulus‐response assumption. The focus on the interplay of functions and the hospitalists' roles lead to a more comprehensive picture of the patient‐related interaction processes.

Abstract
A welcome sign of the growing recognition of the need for more attention to research and documentation in the social sciences can be found in the Report of the Committee on Social Studies under the chairmanship of Lord Heyworth. Not that the report has a great deal to say on the documentation aspect; it has a few fairly cordial references to libraries, and a paragraph mentioning their inadequacies, with a recommendation that national lending facilities should be provided. But the committee were evidently aware of the need for better collection and dissemination of information, and regarded this as one of the major tasks of the Social Science Research Council, of which Dr Michael Young, Director of the Institute for Community Studies, has now been appointed chairman.

Abstract
This chapter enquires into the contribution of two British writers, Herbert Somerton Foxwell and Henry Riverdale Grenfell, who elaborated upon the hints provided by Jevons towards a description of long waves in the oscillations of prices. Writing two decades after Jevons, they witnessed the era of high prices turning into the great depression of the last quarter of the nineteenth century, the causes of which they saw in the end of bimetallism. Not only did they take up Jevons’s specific explanation of the long fluctuations, but they also based their discussion upon graphical representation of data and incorporated in their treatment a specific trait (the superposition principle) of the ‘waves’ metaphor emphasized by the Manchester statisticians in the 1850s and 1860s. Their contribution is also interesting for their understanding of crises versus depressions at the time of the emergence of the interpretation of oscillations as a cycle, which they have only partially grasped – as distinct from the approach of later long wave theorists.

Abstract
Purpose
Simulation in education has been well documented. Business simulation games (BSGs) are often digital and run by a third-party provider. This can create barriers to engagement from educator and student perspectives. This paper explores a facilitator-led BSG, posing the question: can facilitator-led BSGs provide practical experiential learning experiences within a taught setting.
Design/methodology/approach
Exploratory inductive research recruited a sample of 45 student participants, an external examiner and a module leader. Qualitative data were collected using focus group discussion, participant obsession and facilitator reflection. Mixed-method feedback forms were also used.
Findings
The facilitator-led BSG offered a flexible approach to challenge or problem-based learning, experiential learning, collaborative learning and critical reflection. Student feedback was positive, and there was an increase in engagement within all elements of the module.
Originality/value
This paper presents a case study example of the implementation of a facilitator-led BSG, providing an alternative solution for teaching practitioners to structured simulations run by third-party hosts. This paper highlights a flexible approach to student-centric experiential and challenging learning through enterprise education within small-group settings. There are opportunities for further evaluation and exploration of the notion, which can be developed from this paper in future works.

Abstract
This article reports three years' research into the pilot phase of the Social Science Research Council's Open Door Scheme, a scheme designed to facilitate social science research utilisation. Firstly, some general issues of social science utilisation are examined, followed by the background to the creation of the Council's Open Door Scheme to help meet these difficulties. Then, findings from research into the pilot phase of the scheme from 1977 to 1980 are discussed, including its future operation and potential for influencing managerial activity in its widest sense.
