    Recent advances in photovoltaic thermal collectors (PVT): from conventional designs to high insulation glazing and semi-transparent PVT for building applications

    Get PDF
    Photovoltaic Thermal (PVT) systems offer the potential to simultaneously generate electricity and heat from solar energy, achieving significantly higher overall efficiencies than standalone Photovoltaic (PV) or solar thermal collectors. However, despite decades of research since the 1970s, real-world adoption of PVT technology in buildings remains limited compared to separate PV and thermal systems. Prior studies have predominantly focused on improving the performance of conventional opaque PVT panels as standalone systems. Meanwhile, the integration of high insulation glazing in PV and PVT, as well as Semi-Transparent PVT (SPVT) collectors for building applications, remains underexplored. To address this gap, this paper traces the development of PVT systems, beginning with conventional opaque technologies, followed by developments in high-insulation glazing applied to PV and PVT collectors, and concluding with a review of SPVT systems for building integration. To achieve this, the review begins with an overview of PVT innovations published between 2020 and 2025, followed by a focused analysis of high-insulation glazing technologies for PV and PVT (2018–2024), and concludes with a detailed discussion of SPVT advancements (2014–2025). This review identifies a critical gap in the literature: to date, most building-integrated SPVT research has focused mainly on dual functionality (electricity and heat), despite its potential for optical daylighting. Furthermore, no studies to date have investigated real-scale implementation, SPVT–glazing building integration, detailed technoeconomic assessments, or standardized performance evaluation methods for optical, thermal, and electrical outputs. This review highlights these knowledge gaps and recommends future research directions to advance multifunctional solar technologies for energy-efficient buildings

    Building information modeling (BIM) in project management: A bibliometric and science mapping review

    Get PDF
    Purpose: The impact of building information modeling (BIM) on various aspects of project management has attracted much attention in the past decade. However, previous studies have focused on a particular facet of project management (e.g., safety, quality, facility management) and within identified target journals. Despite numerous existing studies, there is limited research on the mainstream research topics, gaps and future research directions on BIM in project management. This study aims to conduct a bibliometric and science mapping review of published articles on BIM in project management and to identify mainstream research topics, research gaps and future research directions in this domain. Design/methodology/approach: A science mapping approach consisting of bibliometric search, scientometric analysis and qualitative discussion was used to analyze 521 journal articles that were retrieved from the Scopus database and related to BIM in project management. In the scientometric analysis, keyword co-occurrence analysis and document analysis were performed. This was followed by a qualitative discussion that seeks to propose a framework summarizing the interconnection between the mainstream research topics, research gaps and future research directions. Findings: Six mainstream research topics were found including (1) BIM-enabled advanced digital technologies, (2) BIM-based reinforcement and enhancement, (3) BIM and project composition, (4) BIM project elements and attributes, (5) BIM-based collaboration and communication and (6) BIM-based information and data. Moreover, this study discussed six research gaps, namely, (1) integration of BIM and other digital technologies, (2) future maturity of BIM applications in project management, (3) application of BIM in project components and processes, (4) role of BIM application in project elements and attributes, (5) impact of collaboration and communication in BIM application and (6) stability of information and data interaction. Furthermore, future research directions were discussed. Originality/value: The findings and proposed framework contribute to providing a deeper understanding to researchers, policymakers and practitioners in the development of related research and practice in the domain of BIM in project management, thus, promoting digital transformation in project management. Overall, it adds to the global knowledge domain in BIM and promotes the need for digital and data integration, BIM maturity and BIM collaboration

    Upholding social hierarchies: Social dominance orientation moderates the link between (intergroup) conspiracy exposure and violent extremism

    Get PDF
    Across two experimental studies, we explored whether exposure to intergroup conspiracy theories can increase violent reactions towards targeted groups. We also examined how ideological attitudes may moderate the effect. In Study 1 (N = 160, preregistered), we found that exposure to immigrant conspiracy theories (vs. control) increased the willingness to use violence for those who reported higher social dominance orientation (SDO) and right-wing authoritarianism (RWA). Study 2 (N = 211, preregistered) sought to extend these results by focusing on a specific target: Muslim immigrants. Exposure to Muslim immigrant conspiracy theories (vs. control) increased motivation and willingness to use violence for those with higher SDO (but not RWA). These findings showcase how exposure to intergroup conspiracy theories and violent reactions are conditional on specific ideological attitudes. Thus, when considering interventions, we argue that it is crucial to consider the role of ideological worldviews when seeking to combat conspiracy-inspired violence

    Cross-Cultural Insights from Two Global Mental Health Studies: Self-Enhancement and Ingroup Biases

    Get PDF
    This commentary highlights two cross-cultural issues identified from our global mental health (GMH) research, RECOLLECT (Recovery Colleges Characterisation and Testing) 2: self-enhancement and ingroup biases. Self-enhancement is a tendency to maintain and express unrealistically positive self-views. Ingroup biases are differences in one’s evaluation of others belonging to the same social group. These biases are discussed in the context of GMH research using self-report measures across cultures. GMH, a field evolving since its Lancet series introduction in 2007, aims to advance mental health equity and human rights. Despite a 16.5-fold increase in annual GMH studies from 2007 to 2016, cross-cultural understanding remains underdeveloped. We discuss the impact of individualism versus collectivism on self-enhancement and ingroup biases. GMH research using concepts, outcomes, and methods aligned with individualism may give advantages to people and services oriented to individualism. GMH research needs to address these biases arising from cross-cultural differences to achieve its aim

    Effects of embedded walls on tunnelling-induced sandy ground displacements: a numerical investigation

    Get PDF
    Urban tunnelling projects pose significant risks to the integrity of nearby structures due to ground movements induced by the excavation process. Embedded walls are commonly employed as a protective measure to mitigate these adverse effects. This paper presents a comprehensive numerical investigation into the effects of embedded walls on tunnelling-induced ground displacements, aiming to provide insights and recommendations for optimal embedded wall design. The study assesses the impact of varying embedded wall length and horizontal distance from the tunnel on soil settlement and horizontal displacements. Results demonstrate the complex interplay between embedded wall length, horizontal distance, and ground movement patterns, and the highly non-linear influence of key parameters on embedded wall efficiency (i.e. its ability to reduce settlements). A preliminary design chart is proposed to guide engineers in determining the appropriate horizontal location and depth of embedded walls to effectively reduce tunnelling- induced ground displacements. The findings contribute to a better understanding of embedded wall performance in the context of tunnelling and provide valuable guidance for the practical design and implementation of protective measures in urban areas

    Risk, the COVID-19 pandemic, and organizations: Extending, repurposing, and developing theory

    Get PDF
    The COVID-19 pandemic has challenged and changed organisations. While the pandemic has brought opportunities for business in some sectors, such as information and communication, and for people who enjoy the flexibility they gain from home-based or hybrid work arrangements, the realization of benefits for individuals and organisations is uncertain over longer time periods and distributed unevenly across the workforce. Thus, the pandemic situation has been a trigger, albeit an unwelcome one, for revising our theorizing about organisational risk. We build on the articles within our special section and develop a perspective on how to continue the development of new theoretical insights. First, we examine how existing theories can be extended to encompass organisational risk. We focus on theories of organisational culture to do so. Second, we discuss ways that existing theories can be repurposed to address important challenges. We illustrate our points using paradoxical leadership theory and theories of creativity. Third, we reflect on ways to develop new theorizing by exploring multilevel modelling and the microfoundations of organisational risk. Fourth, we reflect on methods. In doing so, we pave the way for future studies that will enrich our understanding of organisational risk and contribute to preparations for future crises

    A bioecological approach to conceptualising posttraumatic growth in psychosis

    Get PDF
    Background: Posttraumatic growth (PTG) refers to positive psychological changes arising from adversity. PTG in psychosis is an emerging area of focus, however the individualistic conceptualisation of PTG has been questioned. We extend these debates to consider environmental influences on PTG in psychosis.Methods: In this paper, we outline the application of Bronfenbrenner’s Bioecological Model to PTG in psychosis.Results: The Bioecological Model comprises six ecological systems; 1) biophysical (individual characteristics), 2) microsystem (immediate environment), 3) mesosystem (system interactions), 4) exosystem (impact on individual despite minimal participation), 5) macrosystem (cultural/societal influences), and 6) chronosystem (time).Discussion: PTG in psychosis research has predominately focused on the biophysical ecosystem. We argue that extending PTG research to address the other systems will be advantageous, providing an ecologically valid conceptualisation of PTG and the development of a causal model of PTG in psychosis. Implications for future research are discussed

    Why bother with arts education in schools?

    Get PDF
    Enrolments in school arts subjects are falling in both England and Australia. There are various arguments made in an attempt to reverse the situation. The arts are said to be vital for the economy, linked to success in core school subjects, are educationally inclusive and important for their disciplinary knowledges. In this paper, based on my Radford lecture, I canvass these arguments, concluding that arts education, like the arts themselves, are complex and refuse simple reductions. I speculate about what this might mean for the arts and broader education research community

    The human HELQ helicase and XRN2 exoribonuclease cooperate in R-loop resolution

    Get PDF
    The human HELQ helicase is a superfamily 2, 3’-5’ helicase homologous to POLQ and RNA helicases of the Ski2-like subfamily. It is involved in diverse aspects of DNA repair and is an emerging prognosis biomarker and novel drug-target for cancer therapy. HELQ interacts with RPA via its inherently disordered N-HELQ domain and hence recruited to RPA-bound DNA substrates. Our study reveals a novel role for HELQ in R-loop resolution. We show in cells and in vitro that HELQ is recruited by RPA at R-loops, which are then resolved if HELQ is catalytically active as an ATPase/helicase. Furthermore, we identify a functional interaction of HELQ with XRN2, a nuclear 5’ to 3’ exoribonuclease, which we suggest coordinates R-loop unwinding by HELQ with RNA digestion by XRN2. Collectively, we assign a new biological function for HELQ in genome stability in metazoans through its involvement with XRN2 in R-loop metabolism

    Digital platform capability and innovation ambidexterity: The mediating role of strategic flexibility

    No full text
    Despite growing research recognising the role of digital capability in enabling innovation strategy and outcomes, we know little about how firms can effectively adapt to shifts in innovation paradigms caused by digitalisation by leveraging digital platform capability to attain innovation ambidexterity. Drawing on dynamic capability theory (DCT), this study explores the influence of firms’ digital platform capability on innovation ambidexterity by analysing a sample of 312 Chinese manufacturing firms. We find that digital platform capability has a positive effect on innovation ambidexterity via the mediating role of strategic flexibility. Market turbulence positively moderates the relationship between digital platform capability and strategic flexibility. These findings enhance our understanding of the mechanisms by which digital platform capability influences innovation ambidexterity
