One of the major challenges in combatting biodiversity loss concerns range-restricted taxa that are of conservation importance because of their reduced and threatened populations. Astragalus is a genus with many polymorphic species, adapted to arid and semi-arid ecosystems, some of which require urgent conservation attention. Astragalus centralis E. Sheld., endemic to Uzbekistan, is known from a single population in the Tamditau low mountains of the Kyzylkum Desert. Its population is extremely small and continues to decline as a result of threats from limestone extraction, overgrazing, climate change and extreme weather events. Field assessments indicate that this plant is at high risk of extinction, with limited regeneration capacity and ongoing habitat degradation. Using the IUCN Red List criteria, we assess A. centralis as Critically Endangered. Urgent conservation measures are necessary to secure its survival, including habitat protection, conservation translocation, ex situ propagation and regulated grazing, and the ecosystem in which this species occurs should be assessed for the IUCN Red List of Ecosystems. Raising public awareness and securing international recognition for the species are also required. This study highlights the significance of taxonomy in identifying species of conservation priority. The recognition of A. centralis as a unique species has led to it being identified as in urgent need of protection, and reaffirms the importance of taxonomic reassessments in conservation.

In a time of mass global e-waste production, a re-evaluation of re-purposing and recycling practices feels particularly relevant not only in life but also in art-making processes, especially in temporarily mounted installations, both sonic and visual. What is junk and what is useful material? Can the use of salvaged materials also encourage creativity and innovation? This paper, weaving in theoretical frameworks from sound studies, media archaeology and eco-sonic aesthetics, suggests that using mismatched ‘garbage’ loudspeakers and unconventional loudspeaker arrays can offer sound artists creative opportunities for the exploration of new aural spaces and spatial and timbral possibilities, through the formation of sounding sculptures. Examining Social Sciences and Humanities Research Council-funded sound and art installation Waste Whisperer (2023) as a case study, which involved a bespoke 40 loudspeaker set-up of salvaged ‘trash’, the article also explores the work of artists such as Benoit Maubrey, John Wynne and Nor Tijan Firdaus, who use discarded e-waste as their primary sculptural materials, as well as Paul Rogers’ research around the concept of ‘sonic junk’. In addition, the concepts of transparency and ‘realism’ in the audio medium are discussed, positing critical reflections on prevailing techno-utopian narratives in contemporary audio communities around ‘matching’ loudspeakers and spatialisation conventions.

This article explores Islamic citizenship education as the conduit through which ideological governance was articulated and enacted in rebel-governed northwestern Syria (2017–25) with a close ethnographic and textual analysis of the Dar al-Wahy al-Sharif (DWS) school network. Founded in 2017 under the patronage of Hayʾat Tahrir al-Sham (HTS), DWS has grown into the region’s most expansive educational institution, blending Qurʾanic learning with nationalist Islamic pedagogy. Drawing on fieldwork conducted in Idlib in 2025, the study examines how DWS cultivates an “exceptional Qurʾanic generation” while operating within, and reinforcing, a political environment structured by HTS rule, shaping patterns of loyalty and parental alignment. Situating DWS within HTS’s post-Salafi turn and broader state-building project, the article argues that the school system functions as both a site of ideological reproduction and an arena in which postconflict Islamist governance takes shape.

In soundscape composition, environmental sounds form a ‘language’ that highlights the voices of the environment for everyone’s contemplation. Ideally, they create an atmosphere and space of listening that allow us to grapple with and perceive more deeply the ecological imbalances, social inequalities, cultural gaps, and political issues in which we find ourselves. With the help of compositional examples, the author traces ways in which soundscape compositions can be a forum for ‘speaking back’ in protest, making oppositional voices heard while simultaneously exploring artistic-poetic expressions for a deeper listening engagement with the sonic complexity of environmental sounds and the meanings they carry within them. Furthermore, the author considers whether and how a soundscape composition can be a relationship-builder between environment and listener: can it be an agent for listening to the land, to the natural world, in ways that make urgent and necessary changes of human behaviour possible?

Let $p$ be a prime, let $1 \le t \lt d \lt p$ be integers, and let $S$ be a non-empty subset of $\mathbb{F}_p$. We establish that if a polynomial $P:\mathbb{F}_p^n \to \mathbb{F}_p$ with degree $d$ is such that the image $P(S^n)$ does not contain the full image $A(\mathbb{F}_p)$ of any non-constant polynomial $A: \mathbb{F}_p \to \mathbb{F}_p$ with degree at most $t$, then $P$ coincides on $S^n$ with a polynomial that in particular has bounded degree-$\lfloor d/(t+1) \rfloor$-rank in the sense of Green and Tao. Similarly, we prove that if the assumption holds even for $t=d$, then $P$ coincides on $S^n$ with a polynomial determined by a bounded number of coordinates.

Some may dismiss the prospect of a decolonial transnational surrogacy as a contradiction in terms. After all, there is a parasitic takeover and expansion of the foetus into the host’s body; and the labor is often extracted by those in the Global North from those in the Global South on exploitative terms. However, I claim that a decolonial surrogacy is not necessarily a misnomer nor unimaginable. To either ban surrogacy entirely or allow it fully under the current system falls into the trap of discussing binaries within limited frameworks that decolonialism seeks to resist. I argue that, if there is to be a decolonial surrogacy, it entails a different system altogether. As such, I present a “tripartite-hybrid” model to decolonize surrogacy: an expanded relational unit, basic services, and targeting multiple norm-based hierarchies. While requiring fundamental changes to current conceptions of family and to broader social structures, the proposals together are ways to deal with the “ontological difference” (limki 2018) in surrogacy and to meet decolonial feminist aims. If, and only if, these requirements are met, is a decolonial surrogacy possible.

This study examined the operational and economic aspects of rice drying and storage practices, focusing on the effectiveness of fumigation methods. Based on three case studies of two rice drying and storage companies of different sizes and a milling company, the study explores the economic viability of utilizing an emerging and sustainable pest control treatment technology—atmospheric cold plasma (ACP) fumigation chamber to the Weevil-Cide (Aluminum Phosphide Pellets) fumigant currently used by many agribusiness facilities and companies. The study employs a capital budgeting approach to evaluate economic feasibility and an input–output model to determine the broader economic impact. The findings revealed that the ACP chamber is more cost-effective for mills rather than drying and storage companies, suggesting that profitability in rice drying and storage is closely tied to the volume processed and stored, and the stage in the production chain. The investment in the novel technology was found to have a significant economic impact on the U.S. economy.

Estimation in exploratory factor analysis often yields estimates on the boundary of the parameter space. Such occurrences, called Heywood cases, are characterized by non-positive variance estimates and can cause numerical instability, convergence failures, and misleading inferences. We derive sufficient conditions on the model and a penalty to the log-likelihood function that guarantee the existence of maximum penalized likelihood estimates in the interior of the parameter space, and that the corresponding estimators possess desirable asymptotic properties expected by the maximum likelihood estimator, namely, consistency and asymptotic normality. Consistency and asymptotic normality follow when penalization is soft enough, in a way that adapts to the information accumulation about the model parameters. We formally show, for the first time, that the penalties of Akaike (1987, Psychometrika, 52, 317–332) and Hirose et al. (2011, Journal of Data Science, 9, 243–259) to the log-likelihood of the normal linear factor model satisfy the conditions for existence, and, hence, deal with Heywood cases. Their vanilla versions, though, can result in questionable finite-sample properties in estimation, inference, and model selection. Our maximum softly-penalized likelihood (MSPL) framework ensures that the resulting estimation and inference procedures are asymptotically optimal. Through comprehensive simulation studies and real data analyses, we illustrate the desirable finite-sample properties of the MSPL estimators.

Despite the proliferation of research, more systematic attempts to trace worker experiences across production networks of renewable energy remain marginal. This limits our potential to offer meaningful insights to guide future political mobilisation and policy measures for organised labour and workers more broadly. As a partial remedy, I provide an initial description of labour processes in wind energy. To do so, I carry out labour regime analysis. The utility of the labour regime framework stems from its ability to help the analyst to understand the labour process better by grounding it into a systematic theoretical framework to capture more effectively how dynamic political economic processes condition workplace outcomes. In my analysis, I highlight how capitals-in-competition within energy production networks facilitate structural conditions that intensify the rate of wind worker exploitation. Critically, the ecological sphere of the labour regime mediates the capital-labour interaction, which helps to explain the significant number of hours and extended timelines expected of wind technicians and those involved on project developments, as project owners push for time intensive schedules to reduce wind turbine downtime. My work also extends labour regime scholarship by arguing that ideational constructions, informed by different spheres of the labour regime, govern the labour process in important ways, which suggests that future studies might more seriously consider how ideational notions of work, such as Gramscian ‘common sense’ expectations, maintain labour regimes. I reason that a combination of these factors, both material and ideational, has made workplace organising in wind difficult.

The family is rarely a topic of international politics, but politicised captivity is one of the few domains where familial relations can play a prominent role. Crucially, the families involved generally lack the traditional power resources of wealth or official status that would normally be understood to influence outcomes within international politics. What they do possess, however, is a different set of emotional–political resources that both evoke emotion and invoke a diverse set of social rules concerning emotional experience. To explore our claims, we examine the case of the family of Yokota Megumi, a thirteen-year-old Japanese girl abducted by North Korea. This case both illustrates the potential of emotional–political resources to mobilise action and also highlights the risks that emotional narratives of families can be leveraged by political actors for their own purposes.

For the module category of an Artin algebra, we generalize the notion of torsion pairs to ideal torsion pairs. Instead of full subcategories of modules, ideals of morphisms of the ambient category are considered. We characterize the functorially finite ideal torsion pairs, which are those fulfilling some nice approximation conditions, first through corresponding functors and then through the notion of ideals determined by objects introduced in this work. As an application of this theory, we generalize preprojective modules, introduce a new homological dimension, the torsion dimension, and establish its connection with the Krull–Gabriel dimension. In particular, it is shown that both dimensions coincide for hereditary Artin algebras.

1. Meta-analyses are a reliable method for a quantitative research synthesis. They are, however, prone to specific biases that can be introduced in the process. Such a bias could exist if primary literature produces similar results if coming from the same authors. Authorship network bias is the non-independence of effect sizes introduced by the overlap of authors of primary studies. If not accounted for, it can severely impact the quality of meta-analysis and the conclusions drawn from it.

2. To account for such non-independence, multilevel models with author clusters as an additional hierarchy level were recently suggested. We propose a new method for the detection of non-independent effect sizes based on authorship networks and for their correction.

3. An analysis of simulated data demonstrates the effectiveness of the here-suggested new method. We further applied our new method to nine exemplary meta-analyses.

4. Our new method for detection and effective correction can be easily integrated in existing meta-analysis workflows, using the functionality already offered by R’s metafor package.

5. Our goal is to enhance the reliability of meta-analyses by highlighting potential authorship network bias and offering a method to address this often-overlooked bias.

Critical minerals are at the centre of divergent state interests defined by developmental objectives, security objectives, energy transition, and sustainability imperatives. Unlike non-critical commodities, they exhibit heightened strategic importance but suffer from significant concentration of supply chains, notably in China. As securitization of trade reshapes global supply chains, governments are looking beyond traditional experiences with international commodity agreements, towards modernized tools of trade and investment cooperation to secure reliable critical mineral supplies. This article offers descriptive and analytical insights into the consequent non-binding international instruments on critical minerals, concluded by the most active participants in this topic: the United States, the EU, Japan, Canada, and Australia, who are amongst the largest demanders and suppliers of these minerals and are all economically developed. It finds that such instruments bear several potential systemic and institutional implications for rulemaking and governance in international trade, which include their ability to divert agency away from the resource rich, the concentration of norm creation and standard creation amongst a few, the phenomenon of ‘selective de-legalization’, and lack of transparency. By highlighting several trends and sources of potential concerns for commodity-dependent countries, this article urges a reassessment of this emerging framework advocating for the need to better balance state interests.

Research shows that increased participation of women in parliaments benefits climate change outcomes. Yet, the actions taken by women parliamentarians to shape these outcomes have not been identified in the literature. I assert that a primary step by which women may generate impact is by championing environmentalism in their speeches before parliament. To test this, I analyse speeches from the UK House of Commons from 2010 to 2021, and find that women MPs both speak proportionately more about the environment than their male counterparts, and bring environmentalism into debates that are not explicitly coded as environmental. Finally, while Conservative women are outnumbered by men, they contribute significantly more to environmental speeches than their male counterparts. These results suggest that women are disproportionately responsible for embedding environmentalism into political discussions across Parliament and the Conservative Party, and prompt questions around the true cost of unequal representation for our climate.

Clinical and Translational Science Award (CTSA) hubs must advance implementation science via innovative approaches to understand and develop strategies for overcoming barriers to the adoption, adaptation, integration, scale-up, and sustainability of evidence-based interventions, tools, policies, and guidelines. This special communication describes adaption of the I-Corps™@NCATS training program, a Lean Start-Up approach developed to advance commercialization of academic innovation, as a mechanism for building implementation science capacity at the Institute for Translational Medicine, a Chicago-based multi-institutional CTSA hub. Results from seven training cohorts (2021–2025) are presented (43 teams, 157 participants). In this five-week experiential program, teams conducted “customer discovery” interviews with stakeholders (mean = 23.8/team, SD = 5.6) to rapidly assess fit-to-context of their innovation and adoption requirements. Likelihood of recommending the program to a colleague was high (8.9, SD = 1.5; 1–10 scale, where “10” = “extremely likely”). Important adaptations were providing non-commercial use cases; defining “customers” in terms of stakeholders and partners; reframing commercial business model goals in terms of designing-for-dissemination-and-sustainability; and showing how the value proposition hypothesis is analogous to a research hypothesis being tested and validated with “customer discovery” data. Findings support that the modified I-Corps@NCATS training program provides flexible translational science skill-building to advance implementation science capacity among clinical and translational researchers.
