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).

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.

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.

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.

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.

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

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.

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.

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.

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.”

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.

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.

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.

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.

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.

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.

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.

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.

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.

Young people are widely known to have poorer outcomes, social status and political representation than older adults. These disadvantages, which have come to be largely normalized in the contemporary context, can be further compounded by other factors, however, and are particularly amplified by coming from a lower social class background. An additional challenge for young people is associated with place, with youth who live in more remote and less urban areas at a higher risk of being socially excluded (Alston & Kent, 2009; Shucksmith, 2004) and/or to face complex and multiple barriers to employment and education than their urban-dwelling peers (Cartmel & Furlong, 2000). Drawing upon interviews and focus groups in a qualitative project with 16 young people and five practitioners, and using Nancy Fraser’s tripartite theory of social justice, this paper highlights the various and interlocking disadvantages experienced by working-class young people moving into and through adulthood in Clackmannanshire, mainland Scotland’s smallest council area.

Children and young people’s time is generally structured by adults’ ideas and interests, be it in the family (sleeping or eating times), in the social world (time of school) or in the cultural realm (holidays and festivities). Children’s autonomy of how they spend their time is reduced to certain spaces, which again are assigned to them by adults. For the past two decades, digital media has entered many people’s – adults as well as children’s and young people’s – everyday life.

With the omnipresent and growing use of digital media by young people – fueled even more by mobile devices – grows a discourse around possible (negative) effects and supposedly necessary pedagogical monitoring and restrictions of their digital media time.

These discussions regarding negative effects on well-being and school performance include formal recommendations for limiting the quantity of time spent online. Hereby, mainly the digital time outside school is addressed and potentially problematized. Despite numerous studies on the effects of digital media time on different aspects of young people’s lives there is little research asking for children’s and young people’s perspectives on digital media use and time.

This study uses questionnaires (509) and qualitative interviews (15) to explore young people’s perspectives in terms of meaning, quality and quantity of the time spent with digital media. The participants were youth aged 12–20 from northern Germany. Using qualitative content analysis, findings point to a necessary differentiation between the purpose of usage, respective effects and evaluations.

Accordingly, being online can be an act (a) of self-actualization including positive effects creating great meaning for well-being, identity and appropriation of the digital world for their own future, (b) a waste of time when, for example, using social media or gaming to pass the time including a feeling that time is accelerated and rushing, personal regrets and references to loss of control and the need for self-control, and (c) a pragmatic naturalization of the digital as one part of life for various individual or social purposes and developments.

The article discusses young people’s evaluations and perspectives addressing the possibly artificial adult differentiation of analog and digital time or activities as well as adults’ presumptions about young people’s digital time and the strive for control resulting from these. Additionally, insights from the circumstances of the COVID-19 lockdown are included in gaining knowledge about what is actually important and rewarding when young people spend time digitally. The chapter aims at an intergenerational understanding of the significance of digital media in young people’s lives questioning alarmist scenarios of a generation that is lost in the digital world.

Children experience toxic stress if there is pronounced activation of their stress-response systems, in situations in which they do not have stable caregiving. Due to their exposure to multiple poverty-related risks, African American children may be more susceptible to exposure to toxic stress. Toxic stress affects young children’s brain and neurophysiologic functioning, which leads to a wide range of deleterious health, developmental, and mental health outcomes. Given the benefits of early care and education (ECE) for African American young children, ECE may represent a compensating experience for this group of children, and promote their positive development.
