We introduce a notion of stratification for rigidly-compactly generated tensor-triangulated categories relative to the homological spectrum and develop the fundamental features of this theory. In particular, we demonstrate that it exhibits excellent descent properties. In conjunction with Balmer’s Nerves of Steel conjecture, we conclude that classical stratification also admits a general form of descent. This gives a uniform treatment of several recent stratification results and provides a complete answer to the question: When does stratification descend? As a new application, we extend earlier work on the tensor triangular geometry of equivariant module spectra from finite groups to compact Lie groups.

We construct a model in which all C-sequences are trivial, yet there exists a $\kappa $-Souslin tree all of whose limit levels are vanishing levels. This provides an optimal combination of compactness and incompactness. It is obtained by incorporating a so-called mutually exclusive ascent path to Kunen’s 1978 forcing construction, and by analyzing a gallery of $\kappa $-cc forcing extensions of the outcome model.

The International Law Commission’s ongoing study on subsidiary means identifies a significant pattern: international courts predominantly cite teachings from a narrow cohort of Western, male scholars. The Commission’s response, adopting “representativeness” to ensure geographic and demographic proportionality, while well-intentioned, could reflect a misalignment if this concept is applied formalistically. Unlike state-derived sources of law, teachings derive their authority from analytical rigor rather than representative mandates. This article argues that applying representativeness to scholarly works may misconceive their epistemological function within Article 38(1)(d). We propose a pluralist approach grounded in three interconnected arguments: epistemological (disrupting legalist assumptions about determinacy), dialectical (mediating between formal law and lived experience), and sociological (challenging inherited patterns of judicial reasoning). While acknowledging that both pluralism and representativeness remain susceptible to formalistic application, we suggest a purposive reading of “representativeness” that embraces pluralism as offering a more direct pathway to surfacing the assumptions embedded within legalist methodology.

This article examines how Miskitu King Robert Charles Frederic (1824–42) used colonial contracts with foreign merchants to advance his political agenda in Moskitia, on Central America’s Caribbean coast. Drawing on European and Central American archives, this study challenges narratives that portray Indigenous leaders as passive actors in colonial expansion, highlighting how the king strategically wielded contracts to facilitate the import of foreign capital through concessions and loans. His mastery of international finance enabled resistance to imperial domination while allowing him to consolidate power, maintain independence, and participate in nineteenth-century Atlantic political transformations. However, this strategy compelled him to facilitate the entry of financial capitalism into Moskitia, subsequently defining his kingdom’s fiscal governance and external relations. By examining Robert Charles Frederic’s learning process in navigating Caribbean political and Atlantic financial systems, this article contributes to scholarship on Indigenous agency in colonial encounters and reveals how peripheral actors mediated the global spread of economic institutions.

While the growing representation of women in diplomacy is often celebrated, scholarship on occupational feminisation warns that feminisation can trigger a devaluation of professional work. This article focuses on two conditions identified as inhibitors of such devaluation – the overall status of the occupation and the value accorded to female labour within the occupation – and traces how these two conditions have varied over time and interacted with feminisation in diplomatic work. We contend that in the transition from a classical to a polylateral mode of diplomacy, feminisation has not led to devaluation, as it coincided with an increase in the status of diplomatic work and reinforced the salience of ‘feminine’ skills. However, currently, the rise of populism is undermining these safeguards against devaluation in diplomatic work by constraining the autonomy of diplomats and delegitimising their expert knowledge. To illustrate these dynamics, the article examines the Turkish Ministry of Foreign Affairs (TMFA). We show that the growing diversification and ambition of Turkish foreign policy in the 2000s enhanced the status of diplomatic work and the value of female labour in it. However, by the mid-2010s, these safeguards against devaluation for a more gender-equal TMFA have weakened in the populist–authoritarian political context. Thus, in the context of rising populism in Turkey as well as globally, it is imperative for initiatives to increase women’s representation to be accompanied by strategies that preserve and elevate the status of diplomatic work.

The development of electroacoustic music in China over the past four decades has been shaped not only by the nation’s modernisation strategies but also by the interplay of historical contexts, temporal frameworks and cultural connotations. While certain achievements have been made in the current phase, the entrenched dualistic framework of ‘China versus the West’ and a lack of critical inquiry fundamentally constrain the potential for further advancement in China’s electroacoustic music. Positioning ‘Chineseness’ as a central strategy in electroacoustic music composition has proven effective in specific historical contexts. However, with the evolution of the times, this strategy requires re-examination and reassessment within contemporary contexts. This paper seeks to trace the developmental trajectory of electroacoustic music in China and analyse existing academic research to identify and unpack its deeper, underlying issues. By introducing a broader ecological perspective, the paper aims to transcend the rigid, dichotomous framework dominated by Chinese-Western dualism, deconstruct cultural essentialism and critically reassess the positioning of Chinese electroacoustic music within these constructs. Finally, it will explore the potential possibilities and responses of an ecological perspective in practice, based on a selection of compositional practices, including my own work Mixobloodify.

An increasing number of reports highlight the potential of machine learning (ML) methodologies over the conventional generalised linear model (GLM) for non-life insurance pricing. In parallel, national and international regulatory institutions are accentuating their focus on pricing fairness to quantify and mitigate algorithmic differences and discrimination. However, comprehensive studies that assess both pricing accuracy and fairness remain scarce. We propose a benchmark of the GLM against mainstream regularised linear models and tree-based ensemble models under two popular distribution modelling strategies (Poisson-gamma and Tweedie), with respect to key criteria including estimation bias, deviance, risk differentiation, competitiveness, loss ratios, discrimination and fairness. Pricing performance and fairness were assessed simultaneously on the same samples of premium estimates for GLM and ML models. The models were compared on two open-access motor insurance datasets, each with a different type of cover (fully comprehensive and third-party liability). While no single ML model outperformed across both pricing and discrimination metrics, the GLM significantly underperformed for most. The results indicate that ML may be considered a realistic and reasonable alternative to current practices. We advocate that benchmarking exercises for risk prediction models should be carried out to assess both pricing accuracy and fairness for any given portfolio.

The contribution that coal miners made to the reconstruction of Europe is hard-wired into popular memory, with widespread tales of the selfless sacrifice that saw miners conduct extra shifts and work longer hours for the nation. This article compares three conflicts that arose when miners were ordered to go the extra mile: the campaign to have miners in the Nord-Pas-de-Calais basin (France) make up public holidays in early 1945, the extension of the Saturday shift in the coal mines of the Ostrava-Karviná basin (Czechoslovakia) in late 1946, and the calls on miners in the Ruhr basin (Germany) to conduct extra shifts to provide the population with coal for the winter of 1946/47. Where trade unionists invoked patriotic sentiments and, when that failed, ethnic resentments to motivate miners to go the extra mile, this article shows that generational conflict between old and young miners was the driving force behind these disputes.

Algorithmic management (AM) is reshaping work in many industries. However, what is done to redress potential risks is little understood. This study explores how trade unions, employers, and government actors assess AM-related occupational safety and health (OSH) risks and their strategies to understand how industrial relations could influence the safety and health of workers managed by digital technologies. Drawing on the Pressure, Disorganisation and Regulatory failure (PDR) model and interview and document data from Sweden, we find a gradually increasing interest in AM in the early 2020s among the government and the social partners. Unions learn, inform, and bargain about AM; employers enact ‘healthy discipline’; and government agencies inspect digital risks in workplaces. Moreover, economic and reward pressures contribute to AM-associated OSH risks. Disorganisation manifests as a lack of knowledge about the OSH effects of AM, leading to ineffective OSH management. Regulatory failure is reflected in new EU regulations stalling national-level initiatives, since the overlapping regulations complicate the enforcement of existing OSH regulations. This study highlights the crucial role of trade unions in advancing the agenda on AM-related OSH risks. It also makes a theoretical contribution by extending the PDR model, offering insights into the driving forces shaping AM and compromising OSH beyond the workplace level – highlighting wider politico-economic and institutional dynamics influencing OSH.

We consider the Maxwell–Schrödinger equations in the Coulomb gauge describing the interaction of extended fermions with their self-generated electromagnetic field. They heuristically emerge as mean-field equations from nonrelativistic quantum electrodynamics in a mean-field limit of many fermions. In the semiclassical regime, we establish the convergence of the Maxwell–Schrödinger equations for extended charges toward the nonrelativistic Vlasov–Maxwell dynamics and provide explicit estimates on the accuracy of the approximation. To this end, we build a well-posedness and regularity theory for the Maxwell–Schrödinger equations and for the Vlasov–Maxwell system for extended charges.

We study a discrete process on planar convex bodies in which, at each step, a body is replaced by a weighted Minkowski average of itself and its rotation by a fixed angle. Up to translation and uniform scaling, this produces a rigid averaging dynamical system. We give a complete classification of the limit shapes. If the angle is an irrational multiple of $2\pi $, the iterates converge to a disk. If the angle is rational, they converge to the average of finitely many rotated copies of the initial body. We also obtain sharp convergence rates. In the rational case, the decay is uniform and exponential with an explicit constant depending only on the weight and the denominator of the angle. For irrational angles, we prove quantitative rates under a mild number-theoretic condition that holds for almost every angle: low regularity inputs have polynomial decay up to a logarithmic factor, while real analytic inputs have stretched exponential decay. For angles with bounded continued fraction coefficients, we give matching lower bounds along subsequences. These results describe the global attractors of the dynamics and indicate the absence of chaotic behaviour.

Mobile health (mHealth) interventions offer promising ways to enhance access and continuity of mental health services in low-resource settings. However, little is known about the perspective of end users in routine primary care in Nigeria regarding the role of mHealth in mental health care. This qualitative study explored the perspectives of patients, caregivers and healthcare providers on the use of mHealth tools to support access to and continuity of mental health care in Nigeria. Seventeen participants, including persons with lived experience of depression (n=7), caregivers (n=3), and primary healthcare workers (n=7), were purposively recruited from nine primary health clinics in Ibadan. Interviews were conducted in Yoruba, transcribed, translated into English, and analysed inductively using NVivo 15. Participants identified phone calls, Short Message Service (SMS) reminders, and audiovisual content as key facilitators of engagement, self-care and adherence. Caregivers valued direct communication with providers, while healthcare workers used mobile tools for reminders, follow-up and patient education. Flexible use of next-of-kin contacts helped overcome digital barriers. The findings demonstrate that user-friendly mHealth tools are feasible for supporting mental health care in Nigeria, but their success depends on coupling technology with human-centred communication to ensure equitable and continuous care.

This article addresses the expansion of urban public services in major Nordic cities, from 1850 to 1920. We argue that changes in political discourse were the driving force that prompted politicians to act on behalf of the urban public, significantly before the rise of the universal welfare state. The discursive changes are explored through three analytic concepts: publicness, urban citizenship and the welfare city. We start by presenting a short overview of the development of urban public services. Then we demonstrate how these concepts may be used in conjunction to explain the historical changes. Finally, the material effects are discussed in three case-studies, addressing freshwater pipes, public transport and municipal health care, respectively.

Successful coordination around a Duvergerian equilibrium requires accurate and consistent information about parties’ expected electoral support. In practice, such information is often unreliable and rarely available at the local level, thus hindering voters’ coordination. In this paper, we leverage Argentina’s Open, Mandatory, and Simultaneous Primary Elections as a large-scale survey of voter preferences. Using data from 135 municipalities in the province of Buenos Aires (2011–23), we show that a narrower margin between the top-two placed parties in the primary increases both turnout and the proportion of positive votes in the general election, while decreasing electoral fragmentation. We further show that the second-placed party in the primary is substantially more likely to win the election than the third-placed one. Also consistent with theory, these effects are more pronounced (a) in concurrent elections; (b) in smaller municipalities; and (c) when the second-placed party is closer to the first-placed one.

This paper presents an actuarially oriented approach for estimating health state utility values using an enhanced EQ-5D-5L framework that incorporates demographic heterogeneity directly into a Generalised Linear Model (GLM). Using data from 148 patients with Stage IV non-small cell lung cancer (NSCLC) in South Africa, an inverse Gaussian GLM was fitted with demographic variables and EQ-5D-5L domain responses to explain variation in visual analogue scale (VAS) scores. Model selection relied on Akaike Information Criterion, Bayesian Information Criterion, and residual deviance, and extensive diagnostic checks confirmed good calibration, no overdispersion, and strong robustness under bootstrap validation. The final model identified age, gender, home language, and financial dependency as significant predictors of perceived health, demonstrating that utility values differ meaningfully across demographic groups. By generating subgroup-specific estimates rather than relying on uniform value sets, the framework supports more context-sensitive cost-effectiveness modelling and fairer resource allocation. Although developed in the South African NSCLC setting, the methodology is generalisable and offers actuaries and health economists a replicable tool for integrating population heterogeneity into Health Technology Assessment, pricing analysis, and value-based care.
