Abstract

Purpose

To evaluate the temperature-dependency of the Young’s and shear moduli of concrete after exposure to moderately elevated temperatures using the non-destructive impulse excitation technique (IET).

Design/methodology/approach

The study involved heating the concrete up to 225 °C and measuring the dynamic Young’s and shear moduli using the non-destructive technique of impulse excitation, which measures the natural vibration frequency from a mechanical impulse received by an acoustic sensor. The effects of temperature on the dynamic Young’s and shear moduli were analysed and the importance of the spatial variability of the measured values was also verified.

Findings

The study found that even moderately elevated temperatures (below 225 °C) resulted in a significant permanent reduction in the Young’s modulus of concrete (reduction in the range of 23%–36% for the maximum temperature considered in this research) as well as a modest and permanent reduction in the shear modulus of around 6%. It was also observed that spatial variability of the mechanical properties of concrete plays an important role in the measured values; higher dispersion of the results was found for the values of the Young’s and shear moduli of concrete measured along the height of the beam. The non-destructive test method used in this study was found to be extremely useful in the investigation of heat-related damage in concrete structures for its ease of use, low time consumption and accuracy. The results were consistent with the published literature.

Originality/value

This study provides important insights into the temperature-dependent behaviour of the dynamic Young’s and shear moduli of concrete and highlights the significance of proper consideration of the spatial variability of the measured values. The use of a non-destructive test method for continuous acoustic testing during heating and cooling proved to be effective, and the findings contribute to the fields of materials science and civil engineering in understanding the effects of elevated temperatures on concrete properties. The findings confirm that IET can be easily used to gather important information in the condition assessment and rehabilitation of concrete structures after a fire event. Further studies to foster the application of this technique to real structures are suggested.

Abstract

Purpose

Heavy episodic drinking in young women has caused concern among many groups including public health professionals. The purpose of this paper is to investigate the experiences of young women’s alcohol consumption so as to facilitate better health education targeting.

Design/methodology/approach

This qualitative descriptive study examines the narratives of 16 young women’s experience of a “night out” framed as the Alcohol Consumption Journey.

Findings

The young women’s Alcohol Consumption Journey is a ritual perpetuated by the “experienced” and “anticipated” pleasure from social bonding and collective intoxication. The data showed three sequential phases; preloading, going out and recovery, which were repeated regularly. The young women perceived that going out was riskier than preloading or recovery and employed protective strategies to minimise risk and maximise pleasure. Alcohol was consumed collectively to enhance the experience of pleasure and facilitate enjoyment in the atmosphere of the night time economy. Implications for health interventions on collective alcohol consumption and perceived risk are presented.

Originality/value

The concept of socio-pleasure is valuable to explain the perpetuation of the young’s women ritualised Alcohol Consumption Journey. The binary concepts of mundane/celebration, individual/collective and insiders/outsiders are useful to illustrate the balancing of collective intoxication with group protective strategies in navigating the edge between risk and pleasure.

Abstract

Allyn Young′s lectures, as recorded by the young Nicholas Kaldor, survey the historical roots of the subject from Aristotle through to the modern neo‐classical writers. The focus throughout is on the conditions making for economic progress, with stress on the institutional developments that extend and are extended by the size of the market. Organisational changes that promote the division of labour and specialisation within and between firms and industries, and which promote competition and mobility, are seen as the vital factors in growth. In the absence of new markets, inventions as such play only a minor role. The economic system is an inter‐related whole, or a living “organon”. It is from this perspective that micro‐economic relations are analysed, and this helps expose certain fallacies of composition associated with the marginal productivity theory of production and distribution. Factors are paid not because they are productive but because they are scarce. Likewise he shows why Marshallian supply and demand schedules, based on the “one thing at a time” approach, cannot adequately describe the dynamic growth properties of the system. Supply and demand cannot be simply integrated to arrive at a picture of the whole economy. These notes are complemented by eleven articles in the Encyclopaedia Britannica which were published shortly after Young′s sudden death in 1929.

Abstract

In the novel, The Member of the Wedding, Carson McCullers probes the American malaise through the longings of a young adolescent girl. Twelve‐year‐old Frankie no longer sees the world as round and inviting as a school globe. No, the world is huge and cracked and turning a thousand miles an hour. Indeed, the world seems separate from herself. In the midst of chaos, Frankie sees her brother's upcoming wedding as a chance to feel connected, to feel that she matters. The story focuses on Frankie's efforts to be a “member of the wedding,” as she recognizes, “they are the we of me.”

Abstract

Purpose

The purpose of this paper is to understand the regime–youth relationship in Macao. It will use the framework by Weiss and Aspinall (2012) to explain the rise of Macao youth activism and the de-harmonization of their relationship with the authorities.

Design/methodology/approach

According to Weiss and Aspinall, the emergence of youth movements in Asia after the Second World War was based on four factors: the development higher education systems, youth’s collective identities, youth’s trust in the ruling regime and transnational flows of activist ideas and inspirations. This paper analyzes the rise of Macao youth through the four dimensions by Weiss and Aspinall.

Findings

The rise of Macao youth movement is attributable to the development of tertiary education, youth’s collective identities, lowered trust in the regime and international inspiration. Better-educated Macao youth have been increasing their demands for political participation while their distrust in the MSAR government pushes their mobilization. The rise of youth movements around the world after the millennium inspires Macao youth activists’ political mobilization. Interestingly, Macao’s youth movement has been gradually integrated into the opposition forces instead of campaigning by youth organizations. In response to youth activism, the MSAR government, however, could not alleviate the youth’s hostility against the authorities, but its repressive approach intensified the regime-youth tension.

Originality/value

The paper includes interviews with leaders of young activists for their understanding of youth movement in Macao. It can serve the purpose for comparative study of youth movement among Asian societies.

Abstract

Purpose

The purpose of this paper is to describe the work of the Children and Young People's Programme of Time to Change, which is England's biggest campaign to end the stigma and discrimination that surrounds mental health.

Design/methodology/approach

The paper draws upon research into the nature and effects of mental health stigma and discrimination on young people and also outlines the strategy of the Time to Change campaign and its initial outcomes.

Findings

The paper includes testimonies from young people with lived experience of mental health problems about the stigma and discrimination they have faced. It also outlines the aims, objectives and stages of implementation of the Time to Change Children and Young People's Programme. The paper particularly focuses on the campaign work undertaken in secondary schools, the social leadership programme for young people with lived experience of mental health problems and the process of designing effective campaign messaging for social media.

Originality/value

Time to Change is England's biggest campaign to end the stigma and discrimination that surrounds mental health. This paper provides a unique insight into the process of developing and rolling out an anti-stigma campaign for young people.

Abstract

At what age should children and teenagers have access to certain subject materials and/or the adult collection in libraries? Parents, school teachers and administrators, organized and unorganized religious, politicians, and the judiciary are among those willing to expound on their firm conviction that certain materials and subjects are harmful to the young. There are also those who, although uncertain about the effect of certain materials and subjects, are willing to opt for restricting access for the young and to demand that librarians be responsible for policing such action. Librarians generally share these ambivalent feelings about library materials and access for children and young adults. Aware of the possible adverse reaction of adults if alleged controversial materials are placed either in the children's or the young adult collection, librarians often choose not to select such materials. A recent letter to American Libraries suggested that librarians place controversial children's or young adult material into adult collections only, thus avoiding confrontations with those adults concerned about “harmful” matter reaching minors. The writer stated that everyone would win; the material would be available, but objections based on access to the material by the young would be thwarted. The writer did not seem to anticipate problems in determining at what age the young person would be allowed access to the adult collection containing this material, nor was a method proposed for defining either controversial or noncontroversial material. However, the “way out” proposed is actually used by some public libraries in the U.S., although a cursory look at library problems over objections to library materials for the young reveals titles and subjects that would be classified as noncontroversial by many.

Abstract

Reproduces the main texts of hitherto unpublished reminiscences of the style and influence, as a teacher, of Allyn Abbott Young (1876‐1929) by 17 of his distinguished students. They include Bertil Ohlin, Nicholas Kaldor, James Angell, Lauchlin Currie, Colin Clark, Howard Ellis, Frank Fetter, Earl Hamilton, and Melvin Knight (brother of Frank Knight who, with Edward Chamberlin, was perhaps Young’s most famous PhD student). There has recently been a revival of interest in Young’s influence on US monetary thought and in his theory of economic growth based on endogenous increasing returns. These recollections of his students (addressed to Young’s biographer, Charles Blitch) shed light on why Young has, at least until recently, been renowned more for his massive erudition than for his published writings.

Abstract

Purpose

The research reported here forms part of a study of children’s participation in children in care reviews and decision making in one local authority in England. The purpose of this paper is to outline the views of 11 social workers and 8 Independent Reviewing Officers (IROs) and explores their perceptions of children’s participation in reviews. The paper considers the barriers to young people participating meaningfully in decision making and how practice could be improved in this vital area so that children’s voices are more clearly heard and when possible acted upon by professionals.

Design/methodology/approach

The data reported here derive from a qualitative cross-sectional study in one English local authority. The entire study involved interviewing children in care, IROs, social workers and senior managers about young people’s participation in their reviews. Findings from the interviews with young people and senior managers have been reported elsewhere (Diaz and Aylward, 2018; Diaz et al., 2018); this paper focusses on the interviews with social workers and IROs. Specifically, the authors were interested in gaining insight into their views about the following research questions: To what degree do children and young people meaningfully participate in reviews? What are the barriers to participation? What can be done to improve children and young people’s participation in reviews?

Findings

During this process seven themes were identified, five of which concerned barriers to effective participation and two which concerned factors that appeared to support effective participation. These are summarised below and explained further in the following sections. Barriers to effective participation: social workers and IROs’ high caseloads and ensuing time pressures; high turnover of social workers and inexperienced staff; lack of understanding and training of professionals in participation; children and young people’s negative experiences of reviews and consequent reticence in taking part; and structure and process of the review not being child-centred. Factors which assist participation: quality of the relationship between the child and professionals; and the child or young person chairing their own review meeting.

Research limitations/implications

Although these findings reflect practice in one local authority, their consistency with other research in this area suggests that they are applicable more widely.

Practical implications

The practice of children chairing their own reviews was pioneered by The Children’s Society in North West England in the 1990s (Welsby, 1996), and has more recently been implemented with some success by IROs in Gloucestershire (see Thomas, 2015, p. 47). A key recommendation from this study would be for research to explore how this practice could be developed and embedded more widely. Previous research has noted the tension between the review being viewed as an administrative process and as a vehicle of participation (Pert et al., 2014). This study highlighted practitioner reservations about young people chairing their own reviews, but it also gave examples of how this had been done successfully and how it could improve children’s participation in decision making. At the very least, it is essential that young people play a role in deciding where the review is going to take place, when it will take place, who is going to be invited and what will be included on the agenda.

Social implications

The paper highlights that in this Local Authority caseloads for social workers were very high and this, combined with a high turnover of staff and an inexperienced workforce, meant that children in care struggled to have a consistent social worker. This often meant that young people were not able to build up a positive working relationship with their social worker, which negatively impacted on their ability to play a meaningful role in decision making.

Originality/value

There have been very few recent studies that have considered professionals’ perspectives of children’s participation in key meetings and decision making, so that this provides a timely and worthwhile contribution to this important area of work.

Abstract

Purpose

This paper aims to discuss how sex and relationship education (SRE) could benefit from considering current levels of young women's empowerment in (hetero)sexual relationships and challenge popular notions of twenty‐first century young women “having it all” and occupying powerful relational and sexual positions.

Design/methodology/approach

This study employed a qualitative research design. Young women were interviewed in focus group and follow‐up single interview discussion. The generated talk was then transcribed and critical discourse analytical techniques were employed to analyse the dialogues of the more sexually experienced young women to explore their narratives.

Findings

In contrast with popular images of sexually experienced young women enjoying promiscuity and caring little about the consequences of their sexual actions, this paper displays how some young women continue to struggle with their (hetero)sexual relationships, and particularly their first experiences of sexual intercourse. The young women in the study did not necessarily experience “empowered” love and sexual relationships, rather their talk about their relational and sexual experiences revealed uncertainties, dissatisfactions and compromises.

Research limitations/implications

This study explores eight discourses from the sexually experienced, six of whom were young mothers, and two discourses of whom were not mothers at the time of interviewing. Accordingly, the discussed perspectives and experiences originated from the sexually experienced, and predominantly from young mothers, and the conclusions drawn are specific to this research context. Future studies could explore the extent to which the discussed findings may also be relevant to other groups of young women.

Originality/value

This paper contributes towards considerations of the inter‐relationships between current public health and wider social, cultural and educational issues. By taking young women's own concerns seriously and organising the content of educational classes around young people's interests and concerns, SRE can increase its potential to impact on the quality of young people's love and sexual relationships over and above reducing teenage pregnancies and sexually transmitted infections (STIs).
