Abstract

Purpose

This paper aims to measure the oil film thickness between the roller and the inner ring in roller bearings by the ultrasonic method. The oil film thickness between the roller and the inner ring in roller bearings is a key performance indicator of the bearing lubrication condition. As the oil film is very thin and the contact region is very narrow, measurement of this film thickness is very challenging. A promising ultrasonic method was used to measure this film thickness, and this method was expected to overcome some drawbacks in other methods.

Design/methodology/approach

A simplified roller bearing only configured one roller, and an inner ring was built up to investigate this measurement. A miniature piezoelectric element is bonded on the inner surface of the inner ring to measure the reflection coefficient from the layer of oil between the roller and the inner raceway. As the width of the line contact region is smaller than the width of the piezoelectric element, a ray model is used to calibrate the reflection coefficient measured. The quasi-static spring model is then used to calculate oil film thickness from the corrected reflection coefficient data.

Findings

The results measured by this method agree reasonably well with predictions from elastohydrodynamic lubrication (EHL) theory. Also, a dynamic displacement of the rig caused by the skid of the roller versus the inner ring was found under light-load and high-speed conditions.

Originality/value

This work shows that the oil film between the roller and the inner raceway in roller bearings can be measured accurately by ultrasound and shows a deal method when the contact width is smaller than the piezoelectric element width.

Abstract

AN INTERESTING CHOICE for re‐issue this autumn in Anthony Blond's Doughty Library of novels by Victorian and Edwardian authors is Leonard Merrick's The Position of Peggy Harper: interesting because Peggy Harper has always been deservedly a favourite of Leonard Merrick's admirers, and these have been many and various; interesting because this novel is highly typical of Merrick's fiction in the realistic vein; and interesting, too, because any revival of enthusiasm for Merrick, a writer who has never quite had his due, should remind us of the great debt that Leonard Merrick owed to another man who, when he died in 1942, had been for a year borough librarian at Stratford on Avon, and whose name might be remembered today in several connexions more often than it is. The librarian was Alfred Wareing and it was he who was responsible for the publication between 1918 and 1921 of a uniform edition of Merrick's works.

Abstract

The death of John F. Kennedy (JFK) was one of the most remarkable facts of the second half of the twentieth century. Not surprisingly, it was reflected numerous times in popular culture, including in popular music. In this chapter, I discuss songs published in the 1963–1968 period in which the image of JFK was represented as an idea, a cultural motif or a political myth created, transformed and maintained by artistic means. In song lyrics, a real person (who was a genuinely influential politician) was portrayed as a person who acquired a certain mythical status, stemming from JFK's charismatic features and augmented by his tragic death. Thus, separate from the real political career as the president, JFK serves as a kind of mythological structure used by several artists to generate meanings and mirror cultural iconography present in American culture.

Abstract

The emphasis of this survey is on motion picture reference material that has been published since 1982. This update does not, for the most part, include titles covered in a prior RSR article (1:4; 1983), written by myself, or in an even earlier article by Leslie Kane (7:1; 1979). In those few instances where titles that have appeared in the earlier RSR film surveys are discussed, it is because they now have a new subject emphasis.

Abstract

Purpose

The purpose of this paper is to examine the value of utilising future studies to explore citizenship for people with mental health challenges.

Design/methodology/approach

This paper critiques the discipline of future studies and considers it in the context of the citizenship and mental health literature. It explores how future studies can be utilised to promote marginalised voices, such as those of people with mental health challenges.

Findings

Technology is leading to rapid change in society including what it means to be a citizen (Isin and Nielsen, 2008; Isin and Ruppert, 2015). Whilst citizenship has been promoted within mental health for a long time, change has been slow (Rowe and Davidson, 2016). In order to create inclusive opportunities for people with mental health challenges, any focus on citizenship in mental health needs to not only address the present time but to anticipate and influence future technological directions.

Originality/value

This paper is original in bringing together mental health and the future impact on society of new technologies. It stands to offer a new perspective to discussions on citizenship.

Abstract

Purpose

The purpose of this paper is to explore the impact of digital technology on citizenship for people with mental health challenges (PMHC). Technology is increasingly dominating our lives and changing what it means to be a citizen. Citizenship approaches such as the 5Rs (Ponce and Rowe, 2018; Rowe and Pelletier, 2012) or collective citizenship (Quinn et al., 2020) are gaining prominence as ways to promote the rights and inclusion of PMHC. Therefore, it is essential to explore the impact of technology on citizenship for PMHC.

Design/methodology/approach

This study was part of a PhD using community-based participatory research (CBPR) conducted alongside 3 peer researchers. Participants (n = 7) were from a mental health peer-led organisation and a digital technology company (n = 4) in England. They participated in semi-structured interviews and a co-production workshop. Data was co-analysed using thematic analysis.

Findings

Participants viewed technology as a means to promote inclusion but also leading to further division and exclusion. Discussions about technology were seen as central to discussions about citizenship. Participants did not see digital citizenship as a distinct concept. Those from the peer-led organisation wanted to play an active role in shaping citizenship.

Originality/value

This is the first published study to specifically focus on exploring digital citizenship in the context of citizenship within mental health. The paper highlights the importance of incorporating the impact of technology on mental health and citizenship and raises implications for mental health citizenship-orientated research, policy and practice.

Abstract

Forensic nursing is a term applied to nurses working in many different areas of clinical practice, such as high security hospitals, medium secure units, low secure units, acute mental health wards, specialised private hospitals, psychiatric intensive care units, court liaison schemes, and outpatient, community and rehabilitation services. Rarely is the term defined in the general literature and as a concept it is multifaceted. Concept analysis is a method for exploring and evaluating the meaning of words. It gives precise definitions, both theoretical and operational, for use in theory, clinical practice and research. A concept analysis provides a logical basis for defining terms and helps us to refine and define a concept that derives from practice, research and theory. This paper uses the strategy of concept analysis to explore the term ‘forensic nursing’ and finds a working definition of forensic mental health nursing. The historical background and literature are reviewed using concept analysis to bring the term into focus and to define it more clearly. Forensic nursing is found to derive from forensic practice. A proposed definition of forensic nursing is given.

Abstract

THE fact that the forthcoming conference of the Library Association is to be held at Eastbourne this year should provide it with an additional official interest, as it is here that the Association Hon. Solicitor and Legal Adviser holds the important office of Town Clerk. Mr. Fovargue is the authority on Library Law in all its aspects, and is the author of several books on this important subject. We are particularly happy in being able to print an article from his pen in our special Conference number. The programme of the proceedings is by now, no doubt, in the hands of our readers, and will be found to be less crowded, but no less useful for that, than in previous years. Apart from the usual business programme, which should prove full of interest, the social side has been fully catered for and delightfully arranged. Several interesting motor trips are to take place, and delegates will be afforded an opportunity of enjoying the charms of the beautiful county of Sussex as well as those of one of our most favoured of seaside resorts.
