This paper aims to study passive control techniques for transonic flow over a backward-facing step (BFS) using square-lobed trailing edges. The study investigates the efficacy of upward and downward lobe patterns, different lobe widths and deflection angles on flow separation, aiming for a deeper understanding of the flow physics behind the passive flow control system.

Large Eddy Simulation and Reynolds-averaged Navier–Stokes were used to evaluate the results of the study. The research explores the impact of upward and downward patterns of lobes on flow separation through the effects of different lobe widths and deflection angles. Numerical methods are used to analyse the behaviour of transonic flow over BFS and compared it to existing experimental results.

The square-lobed trailing edges significantly enhance the reduction of mean reattachment length by up to 80%. At Ma = 0.8, the up-downward configuration demonstrates increased effectiveness in reducing the root mean square of pressure fluctuations at a proximity of 5-step height in the wake region, with a reduction of 50%, while the flat-downward configuration proves to be more efficient in reducing the root mean square of pressure fluctuations at a proximity of 1-step height in the near wake region, achieving a reduction of 71%. Furthermore, the study shows that the up-downward configuration triggers early spanwise velocity fluctuations, whereas the standalone flat-downward configuration displays less intense crosswise velocity fluctuations within the wake region.

The findings demonstrate the effectiveness of square-lobed trailing edges as passive control techniques, showing significant implications for improving efficiency, performance and safety of the design in aerospace and industrial systems.

This paper demonstrates that the square-lobed trailing edges are effective in reducing the mean reattachment length and pressure fluctuations in transonic conditions. The study evaluates the efficacy of different configurations, deflection angles and lobe widths on flow and provides insights into the flow physics of passive flow control systems.

This study aims to examine the relationship between the personality dimensions of consumers and celebrities; the effect of celebrity personality on attitude towards the celebrity; and the effect of attitude towards the celebrity on purchase intention.

Data were gathered from 400 respondents in the North of England to explore the connections between five consumer personality dimensions (agreeableness, extroversion, openness, conscientiousness and neuroticism) and nine celebrity personality dimensions (neuroticism, extroversion, openness, agreeableness, conscientiousness, sincerity, excitement, stylishness and positivity) and were analysed using structural equation modelling.

The findings suggested that some dimensions of consumer personality, i.e. conscientiousness, extroversion and openness, were significantly related to all the celebrity personality dimensions. Moreover, all the celebrity personality dimensions had a significant effect on consumers’ attitude towards the celebrity; however, only neuroticism, extroversion, openness, sincerity and positivity significantly affected purchase intention. Finally, attitude towards the celebrity had a significant effect on purchase intention.

The study introduces a celebrity personality scale and explores a topic that has not previously been researched.

This study aims to explore the experiences of living through the COVID-19 pandemic for people who faced homelessness and dealt with mental health and/or substance use challenges.

This qualitative study was comprised of 26 1:1 interviews (16 men and 10 women), conducted between February and May 2021 with people who experienced homelessness in North East England during the COVID-19 pandemic. An inductive reflexive thematic analysis was undertaken, with input from individuals with lived experience who were involved throughout the study.

Four themes were developed. The first theme, lack of support and exacerbation of mental health and substance use difficulties, highlighted how the lack of in-person support and increased isolation and loneliness led to relapses or new challenges for many people’s mental health and substance use. The second theme, uncertainty and fear during the pandemic, explored how the “surreal” experience of the pandemic led to many people feeling uncertain about the future and when things would return to normal. The third theme, isolation and impacts on social networks, discussed how isolation and changes to relationships also played a role in mental health and substance use. Finally, opportunity for reflection and self-improvement for mental health and substance use, explored how some people used the isolated time to re-evaluate their recovery journey and focus on self-improvement.

The experiences shared within this study have important implications for planning the future delivery and commissioning of health and social care services for people facing homelessness, such as sharing information accessibly through clear, consistent and simple language.

As one of the few papers to involve people with lived experience as part of the research, the findings reflect the unique narratives of this population with a focus on improving services.

Factors that may influence risk and/or vulnerability to young people’s involvement in terrorism are currently unclear. Understanding the factors that contribute to a young person’s risk profile is a high priority for Youth Justice Services to enable the development of targeted interventions and subsequent risk reduction. The purpose of this study is to systematically identify and critically review studies relating to young peoples’ involvement in terrorism to understand potential risk and/or vulnerability factors and the implications for intervention.

Literature was evaluated using the systematic review method. Twelve papers were selected for the systematic review according to the inclusion criteria.

Twelve factors emerged that indicated relevance to terrorism by young people and were combined into five overarching themes: contextual, social, psychological factors, trauma and use of time.

This systematic review is one of the first of its kind relating to terrorism by young people. The reported findings will be valuable to practitioners seeking to understand the risk and vulnerability factors related to terrorism by young people and the implications for intervention. Directions for future research are explored.

The purpose of this paper is to examine the effects of physical environment design (PED) and its antecedents on consumers’ emotional well-being (EWB). Drawing on place identity and emotional theories, the study aims to provide a new perspective to retail store experiences.

A survey of 800 respondents was conducted in London, out of which 764 responses were constructively used. The data was collected from international retail outlets, and structural equation modelling was used to analyse the data.

The empirical results show that PED has a positive effect on consumers’ EWB. Among the antecedents, visual identity does not have any significant effect on PED and EWB. In contrast, communication had a significant effect on PED but did not have any effect on EWB, and further, cultural heritage had a positive effect on both PED and EWB. Further, moderator analysis identifies the boundary conditions under which specific theories hold.

The value of this paper lies in its potential to be used for creating the perfect design planning in retail stores. Significant implications for managers and researchers are highlighted.

This paper presents an innovative approach to develop the principles of retail store’s PED to support the EWB of consumers.

This study aims to examine the mediating effects of corporate governance mechanisms like the board of directors on the association between disruptive technology adoption by audit clients and the risk of material misstatements, including inherent risk and control risk. In particular, the authors study the mediating effects of board characteristics such as board size, independence and gender diversity.

Based on a sample of 100 audit clients listed on the FTSE 100 from 2015 to 2021, this study uses structural equation modelling to test the research objectives.

The findings indicate a significant and negative association between disruptive technology adoption by audit clients and inherent risk. However, there is no significant evidence observed for control risk. The utilisation of disruptive technology by the audit client has a significant impact on the board characteristics, resulting in an increase in board size, greater independence and gender diversity. The authors also find strong evidence that board independence mediates the association between disruptive technology usage and both inherent risk and control risk. In addition, board size and gender exhibit distinct and differential mediating effects on the association and across the two types of risks.

The study reveals that the significant role of using disruptive technology by audit clients in reducing the risk of material misstatements is closely associated with the board of directors, which makes audit clients place greater emphasis on the construction of effective corporate governance.

This study offers essential primary evidence that can assist policymakers and standard setters in formulating guidance and recommendations for board size, independence and gender quotas, ensuring the enhancement of effective governance and supporting the future of audit within the next generation of digital services.

With respect to relevant stakeholders, it is imperative for audit clients to recognise that corporate governance represents a fundamental means of addressing the ramifications of applying disruptive technology, particularly as they pertain to inherent and control risks within the audit client.

This study contributes to the existing literature by investigating the joint impact of corporate governance and the utilisation of disruptive technology by audit clients on inherent risk and control risk, which has not been investigated by previous research.

Young offender mentoring programmes aim to support young people’s desistance from offending, but despite the importance, there remains limited exploration into mentor experiences of supporting the young people. This study aims to explore how a community-based mentoring intervention supports desistance in young offenders by understanding the mentor's experiences, with a specific reflective focus on facilitators and barriers to their work.

Semi-structured interviews were conducted with seven mentors from Northumbria Coalition against Crime, a youth and community service. Interview transcripts were analysed using interpretative phenomenological analysis, with external auditing conducted by the research supervisor.

Two superordinate themes resulted: “Factors for engagement” and “Personal experiences”, with participant disclosures reflecting professional reward and a sense of success. This was interwoven with “burnout”, emotional investment and challenges linked to barriers to effectiveness. Challenges included the young people having external negative influences, multiple individuals involved in a person’s care and the barrier of in person activities during the coronavirus pandemic. The clinical importance of mentoring programmes, implications for future working practice and research limitations are considered.

The clinical importance of mentoring programmes, implications for future working practice and research limitations are considered.

These findings contribute to understanding mentors’ experiences of working with young people in the community, offering critical insight into the mentorship and wider service dynamics. Furthermore, it provides an inaugural evaluation of the Northumbria Coalition against Crime services.

In Hong Kong, over 20,000 private residential buildings will be 50 plus years old by 2039. However, building maintenance has not been owners’ popular interest because of the high cost as well as the complexities in justifying whether the quantities and prices of the maintenance works are reasonable. This paper therefore aims to validate the practicality of adopting Scan-to-BIM: Terrestrial Laser Scan (TLS) and Building Information Modelling (BIM) to perform quantity take-offs (QTO) for estimating building maintenance costs.

A 64-year-old tenement building was selected to conduct a case study. In this instance, the building had undergone a Scan-to-BIM survey approach to generate QTO for the bills of quantities for external painting works. The Scan-to-BIM approach includes site visit, positioning of scanning equipment, assignment of circular scan routes, point cloud registration and identification of residual error. After that, time, cost and quality data were logged into contrast with QTO on as-built plans for external wall plastering works.

The “time”, “cost” and “quality” of the Scan-to BIM practice were then examined and compared with the prevailing practices of manual measurements on as-built drawings. As noted from the results, the initial cost of Scan-to BIM is high, owing to the cost of equipment, software and capable available operators. However, the authors identified that the time and cost can be significantly minimised by developing and implementing efficient practices such as preparing a detailed scan plan, equipping modeller with quantity surveying knowledge, using automated object recognition and 5D BIM software packages such as Vico Office and CostX.

The upshot is that Scan-to-BIM could be one of the measures to advance the clarity in the QTO and estimated price of the maintenance projects.

The practicability of Scan-to-BIM has received limited attention on existing building maintenance project. The Scan-to-BIM approach was examined using a case building of a 64-year-old tenement building. The approach demonstrated in this research study is promised to advance the clarity in the QTO and estimated price of maintenance project.

This paper aims to explore how environmental employment can promote desistance among criminalised children. Research demonstrates that being immersed in and interacting with the natural environment has a positive impact upon well-being and behaviour, including reduced aggressive and violent behaviours. However, how exposure to the natural environment might promote desistance amongst children with persistent criminal involvement is unclear.

This paper examines, through semi-structured interviews and participant observations, the experiences of n = 23 criminalised children aged 16–18 employed in outdoor work at a UK social enterprise.

The findings demonstrate how working in the natural environment can provide a safe space for children, where they can build positive relationships, learn valuable skills and reconnect with the world outside of the high-pressure, conflict-driven spaces in which they typically occupy.

This research highlights the relevance of the setting in which child rehabilitation takes place and the potential role of natural environments in providing places and opportunities which support pro-social identity development and desistance for children.

Contemporary coliving is a rapidly developing housing typology, characterised by high-density private living spaces integrated with various shared, mixed-use amenities. The purpose of this research is to quantitatively examine the spatial configurations of coliving building systems, and the integration of programmatic space labels, to provide insights for architects and researchers into the homogeneity and genotypical patterns embedded within these contexts.

Coliving buildings of various scales from the United Kingdom and the USA were examined using small graph matching and inequality genotypes. The former was adopted to identify a genotype signature and assess homogeneity levels, whilst the latter provided a comparative analysis of the ranked integration values for space labels within these building systems.

Although local samples exhibited superior levels of homogeneity compared to the sample population (n = 18), the latter still evinced a marked homogeneity and no statistical difference in building system integration (mean real relative asymmetry (RRA)). Local large-scale samples showed the greatest homogeneity and building system integration of all sample groups, whilst a statistically significant distinction in building system integration was evident between large- and small-scale samples. However, a comparison of space label integration (RRA) across different building scales demonstrated that a potential genotypical pattern exists between small- and large-scale samples.

Through the identification of homogeneity and integration values related to scale and location, this research establishes an empirical, methodological framework for the generalisable spatial analysis of contemporary coliving buildings. Furthermore, genotypical patterns provide insights into space labels that are most likely to encourage copresence and social encounters between residents.
