Drawing on focus groups conducted with musicians based in England, we discuss how musicians with backgrounds in different genres evaluate the effects of a range of music-related digital platforms on musicians and music culture. Alongside criticisms, some of them familiar from recent public debate and academic research, we identify a number of more ambivalent and even positive perspectives on the platformisation of music. We analyse the divided responses of our focus group participants under three main headings: attitudes towards music streaming platforms and record labels; attitudes towards social media and short video platforms, in particular, their use as promotional and branding mechanisms; and attitudes towards the abundance of data available to musicians from these various kinds of digital platforms. In our concluding comments, we consider the possible objection that musicians’ ambivalent and sometimes positive appraisals might represent misguided or mistaken perspectives concerning the effects of platformisation.
We consider two-dimensional (2-D) free surface gravity waves in prismatic channels, including bathymetric variations uniquely in the transverse direction. Starting from the Saint-Venant equations (shallow-water equations) we derive a one-dimensional transverse averaged model describing dispersive effects related solely to variations of the channel topography. These effects have been demonstrated in Chassagne et al. 2019 J. Fluid Mech.870, 595–616 to be predominant in the propagation of bores with Froude numbers below a critical value of approximately 1.15. The model proposed is fully nonlinear, Galilean invariant, and admits a variational formulation under natural assumptions about the channel geometry. It is endowed with an exact energy conservation law, and admits exact travelling-wave solutions. Our model generalises and improves the linear equations proposed by Chassagne et al. 2019 J. Fluid Mech.870, 595–616, as well as in Quezada de Luna and Ketcheson, 2021 J. Fluid Mech.917, A45. The system is recast in two useful forms appropriate for its numerical approximations, whose properties are discussed. Numerical results allow the verification of the implementation of these formulations against analytical solutions, and validation of our model against fully 2-D nonlinear shallow-water simulations, as well as the famous experiments by Treske 1994 J. Hyd. Res.32, 355–370.
This study explores an emerging yet under-researched group within the Chinese bureaucratic system: grassroots female civil servants. Although there is a growing focus in academia on female officials in China, existing research mainly concentrates on the gender representation and career pathways of high-ranking female officials. This research delves into the work and life choices faced by female civil servants in local governments. Despite official discourse advocating for gender equality, interviews with 21 female public servants from a poverty-stricken county in northern China reveal that the demands of local government work and gender norms impose a double burden on them. Although the civil service is known for its stability, these women often have to put in extra effort into demanding and exhausting jobs, frequently sacrificing promotion opportunities to balance family and caregiving responsibilities. However, they seldom express dissatisfaction with this situation, reflecting the entrenched nature of gender role perceptions. This study provides a new explanation for the underrepresentation of female officials at higher levels from a grassroots perspective and reveals the impact of overloaded bureaucratic work on career mobility.
This brief article explores forms for the verb “melt” in Gyalrongic languages, demonstrating that they are cognates and not Tibetan loanwords. Clarification is made on a phonological rule in Japhug, where w- transforms to m- following a nasal, merging the nasal and w-. The article also suggests that the preinitial m- in Mazur Stau and Geshiza is a fossilized autive prefix, possibly resulting from independent changes or language contact. Additionally, Tangut, Bawang, and Puxi Stosde’s usage of a labial medial -w-/-v- for “melt” is hypothesized as an ancient labial causative infix.
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.
