INVESTIGATIONS into the nature of high speed flow have now been in progress alto‐gether for thirty years, and at a particularly intensive rate during the past ten years. Many of the problems which troubled early workers have now been solved, certain methods of treatment have been developed to a high degree and interest has shifted to new types of problem and new techniques. A stage has been reached when it is appropriate to review the progress made and to point out those fields which remain to be examined. In this and succeeding articles advances in a number of branches of the subject are described. The account is by no means comprehensive and has been limited to those fields in which work remains to be done, which bear some relation to aircraft or rocket design and of which, at the same time, the author has some direct experience, however limited.

IN the first of these articles it was pointed out that normal supersonic flow can be described theoretically, to a first approximation, by the linearized equation of motion. This has the form of the wave equation and governs first order disturbances to fields of uniform flow; for example, flow past thin wings or slender bodies at small angles of incidence, and flow through ducts of varying cross‐section. In the same way small disturbances in a purely subsonic stream can be described by a linearized equation of motion, which can be reduced to Laplace's equation by contracting the co‐ordinate normal to the direction of flow. Transonic flow, in which regions of both supersonic and subsonic flow occur, is not so easily represented.

PARALLEL with the quest for higher speeds in aircraft of the traditional type, there has been a remarkable advance in rocket and missile design in recent years. The German legacy of the V2 gave both East and West a long start in this development, and full advantage of this has been taken in the period of intensive research of the past ten years. Lately the possibility of space travel has made a very profound appeal to people in all spheres and this has caused the pace of research in this field to be stepped up.

IN the March issue of AIRCRAFT ENGINEERING Mr. Falkner establishes a new power index law for the skin friction coefficient of a flat plate with fully turbulent boundary layer.

The rapid changes taking place in education must be bewildering to the layman and even to the average educationalist. Since 1980 a whole range of new courses with new initials and acronyms have been created, so that authors today find it necessary to include a glossary of terms to help the reader find his way through the maze. Here, for example, is a sample of acronyms that have appeared since 1980: ATS, CPVE, CTC, GCSE, RESTART, RVO, TRIST, TVEI, YTS. It is hard to keep up with them all. Before this review is published, we shall see the Government introduce an Education Bill that is going to have a profound effect on the way the education system of this country is run. It will be the most important piece of legislation since 1944. I have therefore tried to select books that deal with the changing scene, and in particular three that are opposed to the present Government's policy.

This study aims to determine whether engagement in a football programme can positively impact the recovery journey of the mental health service users involved from the perspective of the “Kickstart 2 Recovery” (K2R) programme stakeholders. There are many challenges faced by the people with mental health problems, a significant one being social exclusion. Football is a socially valued occupation in Ireland (Moran, 2019) and the K2R programme is an initiative run to combat experiences of isolation and exclusion that those with mental health difficulties may experience.

A descriptive phenomenological approach was taken to the study with the use of semi-structured interviews as the research method. In total, twenty one interviews were carried out and Braun and Clarke’s (2006) thematic analysis was used to analyse the data.

Two themes represent the findings of this paper: the need for pathways and social inclusion, connection and flexibility. These reveal that facilitators are focused on supporting recovery but are unsure of how to overcome barriers to social inclusion. Sports partnerships and programme facilitators have a role to play in accessing community resources, challenging social stigma and creating exit pathways from the group.

This study reveals the challenges footballers with mental health difficulties experience when attempting to become more included in their communities and suggestions on how football programmes, such as K2R, could support their inclusion. These findings add to the body of research analysing the issue of social inclusion for people with mental health difficulties.

This paper aims to elucidate how cultural intermediaries shape the subjectivity of other marketplace actors in fashion, thus preserving the illusio underpinning this field of cultural production.

Narrative interviews were conducted with cultural intermediaries in the fashion industry. These were supplemented with non-participant observations, carried out simultaneously during the research process. Interview transcripts and field notes were analysed using a combination of holistic-content and categorical-content analysis.

As the fashion field is constructed around beliefs as to what constitutes value, the empirical data demonstrate how fashion models’ embody the illusio of the field and authenticate the values, meanings and identities inherent in it through aestheticised and rarefied styles of performance. These activities seduce other market actors and engender a willing suspension of disbelief that in turn mobilises affective intensities resulting in perceptions of legitimacy.

This research adds greater clarity to what cultural intermediaries do when they mediate between economy and culture. To do this, our research is analysed in terms of the ritual performance, the sensibility of the model, the use of the body and the performative fusion.

The paper offers practical implications insofar as it deconstructs the two core ritualistic aspects of the fashion industry which each season yields significant tangible outputs in various forms. The combination of narrative inquiry with observation allows for a better understanding of how these events can be best channelled to mediate the illusio of this cultural field.

To date, there has been very little consumer research that explores cultural intermediaries and less still that offers an empirical glimpse of their performance. This research adds greater clarity to these embodied performances that legitimate other market actors’ suspension of disbelief while also demystifying the ambiguity with which cultural intermediaries are discussed in consumer research.

Argues that cultural influences may not only affect a professional’s implicit concept of what constitutes effective practice, but may also affect researchers’ explicit theories. Suggests that this means that many HRD practices, processes, procedures and language are specific to cultures. Explores some of the reasons underlying the increasing importance placed on cultural issues by multinational companies, touching on a number of theoretical and epistemological debates. Draws no firm conclusions but attempts to locate various positions and boundaries on the universalism‐relativism continuum.

In this survey, we would be concerned, not so much with the sources that provide information directly on companies themselves, as on those which contain composite statistical and other types of data, often required in evaluating corporate and market performance. Some of them relate to corporate reorganizations and taxation, stock prices, price averages and indices, capital adjustments and business and financial ratios. We may also look at some books which explain the organization and functions of national and regional stock exchanges, stock market timing and forecasting techniques, statistical publications describing market activity, and some general guidebooks used often by investors.
