Short-form video platforms have reshaped the practices of record companies and music streaming services, giving rise to new cross-audiovisual platform ecosystems. This article adopts the concept of the ‘platform adaptor’ to analyse how music industry practitioners and content producers in China have adjusted their production, distribution, and promotion strategies in response to the affordances of this emerging industrial ecosystem. It discusses the practices of staff who work with musicians to construct ‘hot songs’ (热歌) that can gain popularity across audiovisual platforms and music streaming services. Connecting theoretical ideas about affordance, platform ecologies, and adaptation, this article contributes to research on how cultural forms are ‘optimised’ to be more amenable to the requirements of platforms. The findings demonstrate that emotional encoding has become a pivotal mechanism through which musical commodities gain value as production processes increasingly conform to shareable short-form video formats within the platform economy.
Just before World War I, the Hudson’s Bay Company (HBC) geographically expanded its trade in the Canadian Arctic to derive profits from Arctic fox fur and secure its position in a global value chain (GVC) delivering fur to metropolitan consumers. The “problem of nature” challenged the company’s business venture. Furthermore, “nature” was made and remade by the HBC’s own capital investments. The fox trade itself changed human ecology. Technology transfers to Inuit modified their hunting regimes to increase the company’s returns of polar bear skins. Though these skins had high potential market value, modes of production introduced by the HBC to the Arctic precluded the company from sending high-quality products to metropolitan dressers. Within a changing Arctic human ecology, the HBC produced one highly valued commodity for the market while producing another from which it could derive only modest profit. The HBC’s fox and polar bear trade at the onset of the last century suggests ways that business empires can set off complex and unanticipated changes in human ecologies and, therefore, the dynamics of nature and business at their very peripheries.
This paper presents an effective approach to a compact antenna system incorporating a single artificial magnetic conductor (AMC), designed to operate in the GSM and WiFi frequency bands. The proposed system features a dual-band AMC single element measuring 60 × 60 mm2 with $\pm90^{\circ}$ bandwidths of 100 and 170 MHz. A comprehensive parametric study was conducted to optimize performance and determine the AMC phase while maintaining the compact size of the antenna system. Significant improvements in gain were observed, from −1.61 to 1.88 dBi at 0.9 GHz and from 3.33 to 5.66 dBi at 2.45 GHz. Additionally, the complete system achieves a compact electrical size of 0.18λ0 × 0.18λ0 × 0.048λ0, with an increased front-to-back ratio of 12.3 and 19.9 dB at both frequencies. Finally, measurements of the fabricated prototype show good agreement with the simulation results.
Psychotic disorders are severe mental health conditions frequently associated with long-term disability, reduced quality of life and premature mortality. Early Intervention in Psychosis (EIP) services aim to provide timely, comprehensive packages of care for people with psychotic disorders. However, it is not clear which components of EIP services contribute most to the improved outcomes they achieve.
Aims
We aimed to identify associations between specific components of EIP care and clinically significant outcomes for individuals treated for early psychosis in England.
Method
This national retrospective cohort study of 14 874 EIP individuals examined associations between 12 components of EIP care and outcomes over a 3-year follow-up period, by linking data from the National Clinical Audit of Psychosis (NCAP) to routine health outcome data held by NHS England. The primary outcome was time to relapse, defined as psychiatric inpatient admission or referral to a crisis resolution (home treatment) team. Secondary outcomes included duration of admissions, detention under the Mental Health Act, emergency department and general hospital attendances and mortality. We conducted multilevel regression analyses incorporating demographic and service-level covariates.
Results
Smaller care coordinator case-loads and the use of clozapine for eligible people were associated with reduced relapse risk. Physical health interventions were associated with reductions in mortality risk. Other components, such as cognitive–behavioural therapy for psychosis (CBTp), showed associations with improvements in secondary outcomes.
Conclusions
Smaller case-loads should be prioritised and protected in EIP service design and delivery. Initiatives to improve the uptake of clozapine should be integrated into EIP care. Other components, such as CBTp and physical health interventions, may have specific benefits for those eligible. These findings highlight impactful components of care and should guide resource allocation to optimise EIP service delivery.
We present a theoretical framework and validation for manipulating instability growth in shock-accelerated dual-layer material systems, which feature a light–heavy interface followed by two sequential heavy–light interfaces. An analytical model is first developed to predict perturbation evolution at the two heavy–light interfaces, explicitly incorporating the effects of reverberating waves within the dual-layer structure. The model identifies five distinct control regimes for instability modulation. Shock-tube experiments and numerical simulations are designed to validate these regimes, successfully realising all five predicted states. Notably, the selective growth stagnation of a perturbation at either the upstream or downstream heavy–light interface is realised numerically by tuning the initial separation distances of the three interfaces. This work elucidates the critical role of the wave dynamics in governing interface evolution of a shocked dual layer, offering insights for mitigating hydrodynamic instabilities in practical scenarios such as inertial confinement fusion.
As intelligence technology advances, the boundaries between humans and machines blur, prompting questions regarding human identity and agency. While opera has traditionally explored such existential tensions, contemporary productions often emphasise technological narratives, potentially overshadowing human-centred perspectives. This article investigates music’s expressive potential to bridge these divergent viewpoints, positing it as a distinct form of ‘listening’ to and ‘knowing’ the world. Through a case study of Hao Weiya’s chamber opera AI Variation (2021), it probes how a musical approach communicates intricate ethical and existential questions posed by advancing AI technologies. The findings reveal that music’s non-linguistic nature creates an experiential space to explore, feel and contemplate human experiences. Orchestral voices craft sonic landscapes that invite contemplation on being and perception in an AI-driven world, and music conveys complexities beyond what words alone can express. The article illuminates how music contributes to a humanist response to technological advances, enriching cultural and philosophical discourse.
Studying rotating convection under geo- and astrophysically relevant conditions has proven to be extremely difficult. For the rotating Rayleigh–Bénard system, van Kan et al. (J. Fluid Mech., vol. 1010, 2025,A42)have now been able to massively extend the parameter space accessible by direct numerical simulations. Their progress relies on a rescaling of the governing Boussinesq equations, which vastly improves numerical conditioning (Julien et al., arXiv:2410.02702). This opens the door for investigating previously inaccessible dynamical regimes and bridges the gap to the asymptotic branch of rapidly rotating convection.
We address the anti-trans/queer panic integral to the ascendance of authoritarian politics in America and respond by calling on all political scientists to “queer” political science by undoing the cisheteronormativity of the discipline. We contend that this is not the special obligation of LGBTQ scholars but all political scientists. In this we follow Eve Sedgwick’s orientation away from a “minoritizing” to a “universalizing” epistemological perspective that situates this responsibility relative to resisting democratic decline.
This study explores the impact of heatwaves on emergency calls for assistance resulting in service attendance in the Australian state of Queensland for the period from January 1, 2010 through December 31, 2019. The study uses data from the Queensland Ambulance Service (QAS), a state-wide prehospital health system for emergency health care.
Methods:
A retrospective case series using de-identified data from QAS explored spatial and demographic characteristics of patients attended by ambulance and the reason for attendance. All individuals for which there was an emergency call to “000” that resulted in ambulance attendance in Queensland across the ten years were captured. Demand for ambulance services during heatwave and non-heatwave periods were compared. Incidence rate ratio (IRR) and 95% confidence intervals (CI) were constructed exploring ambulance usage patterns during heatwaves and by rurality, climate zone, age groups, sex, and reasons for attendance.
Results:
Compared with non-heatwave days, ambulance attendance across Queensland increased by 9.3% during heatwave days. The impact of heatwaves on ambulance demand differed by climate zone (high humidity summer with warm winter; hot dry summer with warm winter; warm humid summer with mild winter). Attendances related to heat exposure, dehydration, alcohol/drug use, and sepsis increased substantially during heatwaves.
Conclusion:
Heatwaves are a driver of increased ambulance demand in Queensland. The data raise questions about climatic conditions and heat tolerance, and how future cascading and compounding heat disasters may influence work practices and demands on the ambulance service. Understanding the implications of heatwaves in the prehospital setting is important to inform community, service, and system preparedness.
