This article presents a comprehensive analysis of the polychrome paintings on the Flower Peking Opera Theatre in Bozhou, Anhui Province, China. A multi-technique approach was employed, including polarized light microscopy (PLM), X-ray fluorescence (XRF), micro-Raman spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy with energy-dispersive spectrometry (SEM-EDS), and Herzberg staining to determine the composition and methodologies involved in the formation of the pigment layer, the white primer, and the ground layer. The analysis identified cinnabar (red), both artificial ultramarine and Prussian blue (blue), a mixture of barite and gypsum (white), a mixture of chromite and Prussian blue (green), and carbon black (black) in the pigment layer. The ground layer was found to consist of clay and plant fibers (cotton and hemp), while the white prime layer was primarily composed of barite and gypsum. This research provides insights for future conservation and restoration efforts. Full article

Acoustically, Baroque theatres have prove remarkably appropriate for opera, and, in the past, little distinction was drawn in design between drama and opera use, except for the inclusion of an orchestra pit, because both music and words were audible and balanced, reverberation times being shorter than in concert halls but longer than in speech auditoria. In a drama configuration, scenery is set in the fly tower on stage, while for opera pieces, in most cases, the orchestra pit platform raises to the main floor level of the stalls to set additional seats rows. Considering the characteristics of the Opera di Roma (IT), the case study, the main physical parameters that contribute to the sound quality are evaluated and compared in relation to the pit position level, in order to understand the possible merits of the covering seats on the pit surface for drama representations and, more generally, for speech activities. Eight different configurations are compared and, to evaluate the acoustic parameters’ sensitivity, the JND (just noticeable difference) is analyzed. The parameters’ trend is described. Full article

Radon exposure poses a significant health risk in underground cultural heritage sites, where limited ventilation and prolonged visitor presence can lead to high radon exposures. While previous studies have concentrated on monitoring and mitigation strategies, few have developed a comprehensive approach that ensures both safe and sustainable site use. This research introduces an innovative methodology that integrates periodic/seasonal radon risk assessment with risk-informed access management based on periodic monitoring and time tracking. This approach is based on: (i) periodic monitoring to obtain representative concentrations; (ii) the calculation of permissible stay durations using a dose-based framework; (iii) implementation via access registration (badges) and procedural measures; and (iv) the application of mitigation measures when concentrations exceed limits (otherwise, the dose is evaluated in accordance with the applicable reference levels). This strategy was implemented and validated at the Roman Theatre in Herculaneum, a unique case study characterised by complex architectural constraints (as the theatre is completely underground) and high cultural significance. Results from years of monitoring, along with ongoing campaigns, demonstrate that this methodology not only reduces radon-related health risks but also enhances visitor experience. This integrated framework provides a replicable model for balancing conservation, safety, and accessibility in underground heritage sites. Full article

This study explores the role of Applied Theatre as a form of cultural mediation in addressing issues of environmental justice within higher education. Eight university professors participated in the study, providing qualitative data through semi-structured interviews that focused on their perceptions of environmental inequalities, their teaching practices, and the potential of theatrical approaches to foster critical engagement with sustainability issues, drawing on their prior use of drama-based methods in university teaching. Using a directed content analysis framework, the study highlights that environmental inequalities are not only material or ecological but are closely intertwined with social relations, access to resources, and collective experiences. The findings indicate that Applied Theatre can create an intermediate learning space where knowledge, emotion, and action intersect, enabling students to engage critically and experientially with social and environmental injustices. Essential conditions for successful integration include targeted professional development of faculty, institutional support, and interdisciplinary collaborations, while challenges such as limited resources, time constraints, and lack of curricular recognition remain significant. The study contributes to the development of a theoretical framework that positions Applied Theatre as cultural mediation in higher education, framing it not only as an artistic methodology but also as a social and educational practice. This framework provides directions for future research and policy, particularly in the design of sustainable teaching practices that connect higher education with social justice and ecological responsibility.

Background: Frontal sinus (FS) injuries carry high morbidity; however, currently, there is no universally agreed-upon treatment approach for frontal sinus and frontobasal trauma. Objective: This study sets out to evaluate surgical outcomes in frontal reconstruction, looking at how fracture patterns and operative variables impact complication rates. Methods: This was a retrospective cross-sectional study which identified a cohort of 137 patients between the years 2015 and 2022 who sustained frontal sinus fractures at a level one major trauma centre in Central London. The electronic patient record (EPR) and pre-operative computed tomography (CT) were analysed to assess the following factors: patient demographics, injury parameters, surgical technique, and complications. Statistical tests included Pearson’s chi square for categorical variables/nominal data. Mann–Whitney U and Kruskal–Wallis H tests were also used to analyse continuous variables. Results: Overall, 12 of the 91 patients who were treated surgically had major complications (n = 12, 13.2%). In total, 5.5% (n = 5) had return to theatre (RTT) for cerebrospinal fluid (CSF) leaks, 5.5% for infection and 2.2% (n = 2) for haematoma or bleeding. FS fracture complexity was predictive of RTT (p = 0.015) and CSF leak (p = 0.015). Frontobasal complexity was predictive of post-operative infection (p = 0.047). Neurosurgical operative involvement and cranialisation was predictive of post-operative infection, CSF leak, and RTT. Conclusions: Understanding risk profiles in the management of FS fractures is vital in order to help clinicians mitigate these risks and also to better educate patients, including during the consent process. Further research could look at the medical and social risk factors that increase complication rates in this patient cohort. Full article

Indoor positioning using commodity WiFi has gained significant attention; however, achieving sub-meter accuracy across diverse layouts remains challenging due to multipath fading and Non-Line-Of-Sight (NLOS) effects. In this work, we propose a hybrid Graph–Temporal Convolutional Network (GTCN) model that incorporates Access Point (AP) geometry through graph convolutions while capturing temporal signal dynamics via dilated temporal convolutional networks. The proposed model adaptively learns per-AP importance using a lightweight gating mechanism and jointly exploits WiFi Received Signal Strength (RSS) and Round-Trip Time (RTT) features for enhanced robustness. The model is evaluated across four experimental areas such as lecture theatre, office, corridor, and building floor covering areas from 15 m × 14.5 m to 92 m × 15 m. We further analyze the sensitivity of the model to AP density under both LOS and NLOS conditions, demonstrating that positioning accuracy systematically improves with denser AP deployment, especially in large-scale mixed environments. Despite its high accuracy, the proposed GTCN remains computationally lightweight, requiring fewer than ${10}^5$ trainable parameters and only tens of MFLOPs per inference, enabling real-time operation on embedded and edge devices.

In recent years, we assisted the exploitation of Artificial Intelligence (AI) that invasively pervades in several instances of everyday life. The potential of this technology promises the automation of human tasks increasing accuracy and efficiency. The integration of AI systems in the orthopaedic field is becoming more and more a concrete reality, so this topic is gaining increasing interest by the scientific community. More and more authors are testing the power of AI in orthopaedics, exploiting the application in routine workflow, and asking if AI could improve clinical and surgical practice. In this brief narrative review, the state-of-art of AI in hip district orthopaedics is presented, particularly focusing on the application of AI tools in the context of radiological images, early diagnosis, clinical datasets, and around operative theatre. Possible future development of AI-hip pathology management is exposed too, and clear doubts about exploits of these tools in clinical practice are also exposed. Full article

Currently, there remains a lack of systematic quantitative analysis of the acoustic impact mechanism of ancestral temple theatres in relation to their core function of opera performance. This paper takes the Zhaomutang—a typical ancestral temple theatre in northeast Jiangxi—as an example, and comprehensively uses on-site mapping, impulse response testing, and ODEON three-dimensional sound field simulation to conduct acoustic sensitivity analysis on five key spatial elements of the theatre. The results show that the theatre has a hierarchical sound field pattern along its depth, characterized by “high in the front, low in the rear, stronger on the sides and weaker in the middle”. The front patio and the Xiangtang support the clarity of Gan opera dialogue and the fullness of singing through early lateral reflections and moderate reverberation (EDT of 0.8–1.1 s, C₈₀ of 3.2–6.1 dB). However, the rear patio and the Qintang show apparent loudness deficiency (G of −1.5–3.2 dB) and lack of spatial immersion (LF₈₀ below 0.23). The most effective optimization comes from the reconstruction of the geometric relationship between performers and audience: moving the performers forward and appropriately raising the stage and audience area floor can significantly shorten the rear area EDT and increase C₈₀ and G; in contrast, the improvement in sound quality brought about by adding a patio cover and raising the gables is minimal, and the changes in various parameters are generally less than 1 JND. Based on this, the “schedule priority—reversible intervention” acoustic maintenance strategy for living heritage is proposed, and it is suggested that reversible reflective components be set in the side corridor to specifically enhance the sense of immersion in the rear area sound field. The study constructs a quantitative correlation framework of space, materials, and sound field, providing methodological support and parameter basis for the acoustic assessment and protective utilization of ancestral temple theatres.

This study explores the impact of integrating formal and non-formal learning in secondary school education through a mixed-methods experimental design. A total of 120 students (aged 14–16) from two secondary schools were randomly assigned to an experimental group (n = 60) and a control group (n = 60). The experimental group participated in a twelve-week interdisciplinary programme that combined traditional curricular subjects with non-formal educational practices such as sports, theatre, art, and community engagement, supported by digital learning platforms. Quantitative data were collected through validated instruments, while qualitative data were gathered through observations, focus groups, and semi-structured interviews with students, teachers, and parents. Statistical analyses (t-tests and ANOVA) revealed significant improvements in intrinsic motivation, psychological well-being, and sense of belonging among students in the experimental group compared to the control group. Thematic analysis of qualitative data confirmed these findings, highlighting increased collaboration, engagement, and inclusion. The results indicate that integrating formal and non-formal education fosters holistic learning, strengthens community ties, and promotes emotional and cognitive development. These findings provide empirical support for policies and pedagogical practices aimed at developing flexible, participatory, and sustainable educational models. Full article

Though higher education has returned to in-person instruction in the wake of the COVID-19 pandemic, demand for online learning continues to increase. This rapid growth in virtual instruction necessitates examining its impact, particularly in skill-based courses that have traditionally been taught in person. Public speaking, a course requiring experiential learning and active engagement, presents unique challenges and opportunities when converted to an online format. This study explores student experiences in an online public-speaking course designed to parallel the structure of traditional in-person instruction, examining whether the essential learning outcomes of a skill-based class can be effectively achieved remotely. Using archival student data (n = 1151) from 2021 to 2024, we conducted a qualitative analysis of student reflections on how in-person pedagogical strategies effectively implemented in the online format influenced their self-concept, mindset, and overall learning experience. Our findings indicate significant improvements in students’ self-concept, growth mindset, self-confidence, and their ability to overcome fears related to public speaking. Additionally, students highlighted unexpected benefits of the online format, including enhanced support for multilingual learners and increased connections between course content and greater future career readiness in utilizing remote communication. These results highlight the potential of well-designed online public speaking instruction to foster skill development, professional preparedness, and inclusive learning. The study has implications for future skill-based online pedagogy and curriculum development. Full article

This study explores how theatre activities can stimulate the social engagement of adolescents based on data collected in a survey carried out within the ForesTEEN project. Drawing on the responses of 144 participants (i.e., adolescents, theatre professionals, teachers, project partners, parents, and audience members), this article compares multi-perspective views of the work of theatre, adolescents’ motivation to participate, perceived barriers, and successful strategies to encourage adolescents’ participation. It has been found that active theatre participation can lead to the improvement of communication skills, empathy, and self-esteem of adolescents. Most significantly, engaging teens in theatre provides a key avenue for social integration. By offering adolescents with different cultures and ethnic identities a platform to be heard, co-create stories, and feel connected to others, theatre is a space of belonging and shared humanity. Theatre is utilised in reducing social and cultural inequalities to allow adolescents to be actively involved in society and develop interpersonal and civic skills. Several recommendations are provided in the study, which illuminate how theatre can be more participatory, accessible, and inclusive, and how it is to be recognised as a strategic tool enabling adolescent social engagement.

Background/Objectives: Surgical Site Infections (SSIs) are among the most common complications of Posterior Spinal Fusion (PSF) in children and adolescents. The rate of SSIs after PSF varies from 0.9% to 3% for idiopathic scoliosis and can be as high as 8.7% for neuromuscular scoliosis due to cerebral palsy. Major factors associated with SSIs include patient’s underlying pathology and comorbidities, the complexity of the procedure, and many extrinsic factors such as the expertise of the surgeon, perioperative antibiotic prophylaxis, length of hospitalisation, and perhaps environmental factors in the operating theatre and the hospital infections rates of the centre at which the procedure is being performed. We sought to identify the overall rate of SSI and possible modifiable risk factors for SSI in children and adolescents treated with PSF in Penteli Children’s Hospital. Methods: A total of 46 consecutive patients accounting for 67 surgeries performed between 2019 and 2024 were included in this retrospective observational study. Inclusion criteria were as follows: patient’s age at the time of surgery less than 22 years, patients treated with PSF only, and more than 9 months postoperative observation. SSI was defined as infection occurring within 90 days of the index procedure. Results: The rate of deep SSI in our department was 6.0%. Older age at the time of surgery and a history of previous spine surgery were risk factors for developing an SSI. Conclusions: Between 2019 and 2024 four cases of deep SSI occurred in our institution, leading to a rate of 6.0% among all PSF cases for this specific time period. Higher age and a history of previous spine surgery were risk factors for SSI in this cohort of patients. Full article

This essay introduces an experiential process through which student actors can explore any Shakespearean play. Anne Bogart’s Viewpoints technique serves as the foundation for a creative process informed by devising exercises and physical composition. In this essay, I demonstrate how this physically based dramaturgical process enables students to pay particular attention to the foundational elements that uniquely shape the story, such as time, space, sound, architecture, and gesture. This process gives student actors the agency to create material inspired by Shakespeare yet infused with their own imagination and curiosity. It allows students to wake up Shakespeare’s text in unexpected ways, embrace collaboration, and embody the richly detailed expression of Shakespeare’s poetic language. This essay aims to be a resource for educators and directors alike who are interested in a collaborative process that can either be integrated into rehearsals or serve as a foundation for classroom-based discussions. As such, this process can be mapped onto any classical or contemporary play, even though this essay features Shakespeare as the foundation for exploration. Full article

As ecological collapse accelerates under the pressures of anthropogenic climate change, adaptation strategies increasingly include technological proxies for nature’s functions. But can ecosystem services (ES) be meaningfully replaced by technology? Revisiting this urgent question first posed by Fitter (2013), we assess the extent to which bio-inspired design—particularly biomimetics—has advanced the capacity to support, enhance, or replace natural ES. We convened an interdisciplinary team to synthesize and refine a comprehensive list of 22 ecosystem services, integrating often-overlooked cultural and relational dimensions. Using this framework, we conducted a large-scale analysis of over 68,000 peer-reviewed publications from the biomimetics and bio-inspired design literature between 2004 and 2025, applying AI-assisted classification to evaluate whether, and how, these technologies map onto specific ES functions and benefits. Our findings reveal both promise and profound limitations. Bio-inspired research engages with 20 of the 22 ES, but over 78% of this work concentrates on five technologically tractable functions—biochemicals, disease regulation, waste treatment, fibre/hide/wood, and fuel. Foundational supporting and regulating services such as pollination, soil formation, and nutrient cycling are almost entirely absent. Moreover, only 3% of technologies described in the academic literature aim to support existing systems; the overwhelming emphasis on enhancement (39%) and replacement (58%) suggests a design paradigm skewed toward substitution rather than coexistence. Intangible, co-produced services—particularly those related to culture, identity, and meaning—remain outside the current reach of biomimetic design. This skew reveals a dangerous imbalance: while certain ES can be technologically approximated, the relational, emergent, and systemic qualities of ecosystems elude replication. Technological replacement must not become a substitute for preservation. Instead, bio-inspired design should be mobilized as a tool for adaptation that amplifies and protects the living systems on which human and more-than-human futures depend. Full article

In eighteenth-century England, anyone attending an opera, an oratorio, or even a church service would typically have had a printed ‘wordbook’ made available to them to read during the performance. Such wordbooks, whether available for purchase or distributed free of charge, contained the words to be sung (the libretto), usually with translations if necessary, and sometimes also explanatory footnotes, prefaces or plot summaries, or lists of dramatis personae. Examining several oratorios of George Frideric Handel, especially Saul and Theodora, this article asks how the wordbook influenced the drama of a performed work and to what extent this impact made it necessary to have an actively reading audience. The article also explores the use of stage directions in oratorio wordbooks, arguing that they provide rich opportunities for the audience’s imagination by suggesting images that the performance alone cannot provide (since English oratorio probably included no stage action). It notes the wordbook’s necessity in determining which singer is portraying which character, as well as the expressive and dramatic use to which these character identifications can be put. And it compares the practices of different oratorio librettists, suggesting great sensitivity to the unique imaginative power of the oratorio-with-wordbook medium. Full article
