Marine protected areas (MPAs) have proliferated to protect marine ecosystems and manage unsustainable fishing, but their outcomes vary by economic and governance contexts. Drawing on a panel dataset spanning 1995–2021 and employing the Pressure–State–Response framework, this study analyses how MPA coverage is associated with overexploited fish stocks and examines Official Development Assistance (ODA). Results show MPAs in high-income countries are associated with lower overexploited catch rates, reflecting robust governance. In low-income nations, however, limited capacity is often linked to ‘paper parks’ with negligible impact. Multi-purpose ODA – supporting sustainability goals – appears more effective than single-purpose ODA and is associated with better conservation outcomes. Integrating MPAs with fisheries management, supported by international assistance for enforcement, appears important for bridging disparities in effectiveness. By highlighting the interplay among economic conditions, governance and funding, this study offers higher-level insights into factors that shape MPA effectiveness, contributing to broader policy discussions on marine conservation.
Since the 1920s, the workers’ movement has been crucial in linking international communism with colonial liberation. From the 1950s, communist trade unions and the World Federation of Trade Unions (WFTU) played a key role in this process. The WFTU forged ties with Afro-Asian unions to challenge Western powers with an anti-imperialist platform. Decolonization opened new opportunities for European workers in their anti-capitalist struggle, prompting unions such as the French Confédération Générale du Travail (CGT) and Italian Confederazione Generale Italiana del Lavoro (CGIL) to build relationships with unions in newly independent African nations. Their focus was mainly on North and West Africa, where socialist movements emerged during the late 1950s and early 1960s. The CGT and the CGIL established solid links with trade unions in Guinea, Mali, and Ghana. Their views, shaped by their affiliations with the French and Italian communist parties, were not consistently aligned. The CGT maintained a Eurocentric approach to African socialism, while the CGIL, aligned with the PCI, supported a “staged” revolution in Africa, where the working class did not occupy a position of leadership. The CGIL and PCI emphasized the role of peasants and workers in building socialism through a “social revolution” that could strengthen the socialist bloc. These differences created tensions in African trade unions and the FSM, leading to the marginalization of the CGIL’s approach. Nonetheless, Italian unionists gained support from African unions and joined the CGT in mediating for workers in Guinea, Mali, and Ghana.
Obsessive-compulsive disorder (OCD) is a complex psychiatric disorder. While existing studies have revealed abnormalities in brain structure and function associated with OCD, there is a paucity of research integrating these two aspects, and the transcriptional patterns underlying these abnormalities remain unclear. This study is a multiscale, exploratory investigation designed to generate hypotheses rather than to test causal mechanisms. We aimed to investigate aberrations in brain structure–function coupling (SFC) in OCD patients and, by integrating gene expression profiles and neurotransmitter maps, to explore the potential molecular and genetic bases of these changes. We recruited 100 medication-free OCD patients and 90 healthy controls, and employed multimodal imaging techniques to systematically analyze abnormalities in static SFC in OCD patients. Subsequently, we conducted transcriptomic analysis to identify genes associated with SFC abnormalities and performed spatial correlation analysis with neurotransmitter atlases to investigate potential links between SFC dysregulation and transcriptional patterns. Our findings demonstrated that OCD patients exhibit significant SFC abnormalities in the right temporoparietal junction (rTPJ). These SFC abnormalities are significantly associated with 2,421 gene expression profiles and the serotonin neurotransmitter system. Gene enrichment analysis revealed that these aberrant genes are primarily involved in key biological processes, such as brain development, synaptic signaling, cell projection development, and regulation of neuronal processes. By integrating multimodal imaging, transcriptomic, and neurotransmitter data, this study provides multiscale evidence for the potential molecular basis of SFC abnormalities in the rTPJ of OCD patients, offering preliminary insights into a possible pathological pathway of OCD.
Many believe that relationships can make a constitutive difference to the moral status of paternalistic treatment. For example, it is often assumed that it’s easier to justify paternalizing a spouse than a stranger. But although this thought is widespread, there exists no detailed account of how relationships could mitigate paternalistic complaints. The aim of this paper is to develop an account of this phenomenon, drawing on the work of Margaret Gilbert and the notion of joint commitments. According to the resulting view, close relations can constitutively mitigate paternalistic complaints by rendering paternalistic interference consistent with the will of the paternalized agent.
Studying exoplanetary atmospheres offers critical insights into chemical compositions, temperature profiles, cloud formations and atmospheric dynamics. Carbon monoxide (CO), an important molecule in biology and astronomy, exhibits distinct spectral features and could be considered a potential biosignature. This work compares the spectral bands of gases emitted by Roseovarius sp. (obtained from the Atacama desert) and theoretical model atmospheres simulating early Earth analogs. We obtained Raman and infrared spectra of the bacteria. Theoretical model atmospheres of early Earth analogs were generated for comparative spectral analysis. The spectra of Roseovarius sp. revealed distinct vibrational modes, including CO at 5.01 $\mu $m (1996 cm−1) which is considered in the context of other biogenic gases in the metabolism of Roseovarius sp. Ultracool dwarf stars, especially those of spectral type M7 and later, are prime targets for observing habitable exoplanets due to their small radii. The James Webb Space Telescope (JWST) and extremely large telescopes (ELTs) will enable the spectroscopic characterization of Earth-like planets orbiting M-dwarfs. Future studies using the JWST sensitivity models PandExo could estimate the number of transits needed to detect CO/CO2 in rocky exoplanet atmospheres, enhancing our understanding of CO detectability.
Women’s sexual and reproductive rights are crucial for achieving gender equality and promoting women’s rights. Across East Africa, there are limited studies about husbands’ knowledge of their partner’s reproductive rights and their associated factors. Hence, this study aimed to assess husbands’ knowledge of partners’ reproductive health rights and associated factors in Central Ethiopia.
Methods:
A community-based cross-sectional study was conducted from March 15 to April 30, 2023, using multi-stage stratified sampling. A structured, interviewer-administered questionnaire was utilized to gather the data, and then SPSS version 26 was employed for analysis. Statistical significance was declared at a p-value < 0.05.
Results:
The overall good knowledge of partners’ reproductive health rights was found to be 47.8% (95% CI: 43.8, 51.8). Age of the husbands 25–35 years (AOR: 2.7; 95% CI: 1.10, 6.6), below primary educational status (AOR: 2.4; 95% CI: 1.3,4.3), primary educational status (AOR: 5.98; 95% CI: 3.10, 11.4), secondary educational status (AOR: 2.1; 95% CI: 1.01, 4.3), above secondary education status (AOR: 8.0; 95% CI: 4.3, 15.2), discussion with a partner (AOR: 3.2; 95% CI: 2.0, 5.2), and vehicle as a means of transport (AOR: 3.3; 95% CI: 2.2, 4.9) were statistically significant for good husbands’ knowledge of partners reproductive health rights.
Conclusion:
These findings indicate that more than half (52.2%) of the study participants had a poor understanding of their partners’ reproductive rights. Therefore, counselling and education should be offered to husbands to ensure equitable access to health services and to disseminate information on reproductive rights, particularly targeting young men.
“The body” became wildly popular in the social sciences and humanities at the end of the twentieth century. The concept anchored hundreds of scholarly articles and books, across a range of disciplines. The present article offers a new answer as to how and why “the body” experienced this meteoric late-century rise. Scholars set out to address a long-running problem in European and American thought: the mind–body problem. To a person, researchers suddenly rejected any sharp delineation between these realms. While warnings against dualism motivated many projects on the body, it only explains the initial rush to this idea. To understand the corporeal turn of the late twentieth century we must attend to the soaring ambition of the body scholars to bridge all of the divisions of modern thought—subject/object, nature/culture, spirit/flesh—at the point of the body. This article analyzes key body books from the fields of theology, political philosophy, sociology, history, black studies, analytical philosophy, anthropology, and feminist philosophy. In the end, it sounds a note of criticism that the corporeal turn rested on a fantasy of control and controllability of flesh.
This article traces the union career of Abdoulaye Diallo, born in French West Africa in 1917, from the united World Federation of Trade Unions’ (WFTU) 1947 Pan-African Trade Union Conference in Dakar to the founding of the Union Générale des Travailleurs d’Afrique Noire (UGTAN) in 1957. The Dakar conference was a turning point: African delegates, including Diallo, compelled the WFTU to address colonial labour exploitation, thereby unsettling representatives of empire. Following the 1949 split, the WFTU increasingly amplified and promoted leaders from Africa, Asia, and Latin America, and Diallo was appointed vice-president. Our analysis of Diallo’s publications reveals his fierce anti-colonialism and anti-imperialism. It also shows how, following the split, the WFTU provided a platform for Africans to express their anti-colonial views to a wider audience through newspapers and WFTU publications. His interventions at meetings of the UN’s Economic and Social Council (ECOSOC) in the early 1950s exposed forced labour and repression to representatives of international organizations while offering unwavering, uncritical support for the Soviet Union. At the WFTU’s Third World Congress in Vienna (1953), Diallo stood out as the leading African delegate, urging workers to organize for liberation. Regionally, he mobilized Francophone West African workers against wage discrimination and colonial coercion, navigating tensions between communist internationalism and emerging nationalist priorities. This study reimagines the WFTU as an anti-colonial arena, shaped by African agency during the early Cold War period.
Planting green (PG), the practice of planting the cash crop into a living cover crop (CC), offers opportunities to maximize CC biomass and weed suppression. The objectives of this study were to evaluate the effects of cereal rye (Secale cereale L.) termination timing and herbicide programs under PG management on cereal rye biomass, Palmer amaranth (Amaranthus palmeri S. Watson) suppression and seed production, corn (Zea mays L.) yield, and economic returns. Field experiments were conducted during 2023 to 2025 under irrigated conditions in south-central Nebraska. The study used a split-plot design, a no–cover crop (NCC) and five cereal rye CC termination timings (at planting, emergence, V1, V2, and V3 corn growth stages) as the main plot factor and four herbicide programs (nontreated, preemergence-only, postemergence-only, and preemergence followed by postemergence [PP]) herbicide as subplot factors. Delaying cereal rye termination from corn planting up to V3 corn growth stage increased cereal rye biomass from 5,992 to 10,888 kg ha−1 in 2024 and from 2,941 to 7,007 kg ha−1 in 2025. Cereal rye terminated at V2 or V3 corn growth stage reduced A. palmeri density, biomass, and seed production by >99% compared with the NCC. Following high biomass conditions, cereal rye provided comparable A. palmeri suppression to herbicide-based programs, and the additional herbicide use offered limited benefit. In contrast, following low-cereal rye biomass conditions (<6,000 kg ha−1), herbicide inclusion remained essential to achieve effective A. palmeri control and minimizing seed production. Corn yield was not affected by delayed cereal rye termination (ranging from 13,110 to 15,660 kg ha−1). Economic analysis indicated that integrating cereal rye CC with reduced herbicide programs (preemergence-only or postemergence-only) maintained profitability ($2,064 to $2,364 ha−1) comparable to the NCC system with PP herbicide program ($2,353 to $2,401 ha−1).
Current research conceptualizes the gender performance of populist leaders in terms of toxic hypermasculinity expressed through their sexist, misogynist, and transphobic rhetoric. This article challenges and complicates this perspective. As hegemonic masculinities, which formerly gained their power through their invisibility, are increasingly contested, they engage in a strategic hybridization by borrowing aesthetic elements from marginalized identities. In contrast to the established hypermasculinity thesis, we contend that right-wing populists, exemplified by Donald Trump, incorporate queer elements in their embodied gender performances. Trump’s masculinity appropriates the subversive spirit of queerness. It conveys reactionary content through rebellious aesthetics, which results in fake subversion. By drawing together insights from populist research with masculinities studies and queer theory, the article makes sense of (1) why Trump employs queer aesthetics, (2) why his followers appreciate his queer performance, (3) why the queer dimension of his masculinity goes unnoticed, and (4) what new light the case of Trump’s queerness sheds on the concept of hybrid masculinities.
As a direct consequence of liquid kerosene injection, aeroengine combustors may be categorized as non-premixed combustion systems, characterized by a swirl-stabilized and highly complex flow field. In addition to the flow of air through the fuel injector, there are a large number of other features through which the oxidizer can enter the heat release region. These can have an impact on local fuel–air mixing, inducing strong spatial and temporal variations in stoichiometry, thereby affecting emissions and combustion system performance. This article discusses a novel statistical methodology, based on principal component analysis (PCA) and K-means clustering, that aims to improve the understanding of fuel–air mixing in realistic aeroengine combustors. The method is applied in a post-processing step to data sampled from a large-eddy simulation, where every chamber inflow has been tagged with a unique passive scalar, which allows it to be traced across space and time. PCA is used to construct a low-dimensional, visually interpretable representation of a spatially localized fuel–air mixing process, while K-means clustering is employed to produce an unsupervised discretization of the flow field into regions of similar fuel–air mixing characteristics. The proposed methodology is computationally inexpensive, and the easily interpretable outputs can help the combustion engineer make better-informed decisions about combustor design.
In this work, we will present evidence for the incompatibility of smoothed particle hydrodynamics (SPH) methods and eddy viscosity models. Taking a coarse-graining perspective, we physically argue that SPH methods operate intrinsically as Lagrangian large eddy simulations for turbulent flows with strongly overlapping discretisation elements. However, these overlapping elements in combination with numerical errors cause a significant amount of implicit subfilter stresses (SFS). Considering a Taylor–Green flow at $Re=10^4$, the SFS will be shown to be relevant where turbulent fluctuations are created, explaining why turbulent flows are challenging even for current SPH methods. Although one might hope to mitigate the implicit SFS using eddy viscosity models, we show a degradation of the turbulent transition process, which is rooted in the non-locality of these methods.
Two-fluid simulations using local Landau-fluid closures derived from linear theory provide an efficient computational framework for plasma modelling, since they bridge the gap between computationally intensive kinetic simulations and fluid descriptions. Their accuracy in representing kinetic effects depends critically on the validity of the linear approximation used in the derivation: the plasma should not be too far from local thermodynamic equilibrium (LTE). However, many of the problems where these models are of particular interest (such as plasma turbulence and instabilities) are in fact quite far from LTE. The question then arises as to whether kinetic-scale processes are still sufficiently well captured outside of the theoretical regime of applicability of the closure. In this paper, we show that two-fluid simulations with Landau-fluid closures can effectively reproduce the energy spectra obtained with fully kinetic Vlasov simulations, used as references, as long as the local closure parameter is appropriately chosen. Our findings validate the usage of two-fluid simulations with a Landau-fluid closure as a possible alternative to fully kinetic simulations of turbulence, in cases where being able to simulate extremely large domains is of particular interest.
Flame–wall interaction (FWI) of lean premixed hydrogen/air flames is critical in wall-bounded combustors, where thermodiffusive instabilities strongly influence quenching. To capture these effects efficiently in realistic configurations, reduced-order combustion models such as flamelet tabulation are desirable, as they lower resolution requirements and computational cost. In this study, advanced flamelet manifolds incorporating a mixture-averaged species diffusion model and thermal diffusion are developed to represent the FWI of thermodiffusively unstable lean hydrogen/air flames. A central challenge is the simultaneous capture of intrinsic instabilities and heat losses, each complex in itself. Separate manifolds addressing these effects are first introduced, providing the foundation for joint manifolds that capture both simultaneously. In this context, the choice of flamelet databases is examined by comparing freely propagating flames with exhaust gas recirculation, commonly used in flamelet modelling to represent enthalpy variations, with one-dimensional head-on quenching (HOQ) flames, which are essential for accurate prediction of wall heat flux and pollutant formation in hydrocarbon flames. The models are evaluated through both a-priori and a-posteriori analyses across increasingly complex configurations, culminating in the HOQ of a thermodiffusively unstable flame, where both instability and quenching must be captured simultaneously. Results show excellent agreement with reference simulations using detailed chemistry, accurately reproducing key features of the flame front, thermochemical state and global flame properties such as consumption speed and quenching wall heat flux. This marks a key advance in modelling hydrogen combustion and provides a robust foundation for studying safety-critical phenomena such as flame flashback linked to near-wall flame propagation.
This article explores how informal medicine sellers (IMSs) in Mexico City “contest” and “reassemble” antibiotic control standards in ways that both challenge and respond to antimicrobial resistance (AMR) governance. Drawing on ethnographic fieldwork, we examine the “rationales”—moral, political, economic, technoscientific, and practical—that IMSs invoke to justify bypassing antibiotic prescription, dispensing and accounting regulations, and the “practical tinkering” they perform to make antibiotics available and “appropriately” used under conditions of scarcity and oversight failure. Rather than viewing IMSs as simply breaking official rules, we adopt a “social life of standards” perspective to argue that their actions reflect localized enactments of antibiotic control—versions shaped by community needs, corruption, poverty, and distrust in public health infrastructures. These practices are ambivalent, blurring boundaries between public service and profit and systemic subversion and informal regulation. By tracking how IMSs adapt, collectivize, and sometimes deliver treatments, we show how antibiotic governance is reworked from below—not only in response to AMR, but also to structural exclusions from formal care. We argue that rather than treating IMS rationales and practices as part of the problem, they should be studied as grounded responses to systemic failure—and potential sources of insight for context-sensitive regulatory design.
This response describes the development of a comprehensive approach to sustainability education that is embedded in the curriculum and school culture and involves all actors in a school working together. The authors use their school in Mexico City, a city that is directly impacted by the climate and environmental crises, as an example. The school’s efforts include arts projects on topics such as ‘La Tierra Es Mi Amiga’ (The Earth Is My Friend), themed days and weeks focused on sustainability, curriculum design that incorporates direct engagement with the natural world and outreach to experts. They also utilise philosophy for children and debating to encourage critical thinking and empathy and support student-led social enterprise projects focused on sustainability.
We present a new use of Answer Set Programming (ASP) to discover the molecular structure of chemical samples based on the relative abundance of elements and structural fragments, as measured in mass spectrometry. To constrain the exponential search space for this combinatorial problem, we develop canonical representations of molecular structures and an ASP implementation that uses these definitions. We evaluate the correctness of our implementation over a large set of known molecular structures, and we compare its quality and performance to other ASP symmetry-breaking methods and to a commercial tool from analytical chemistry.
This article examines the V3 particle så in Fenno-Swedish, where the particle can follow both initial arguments and adjuncts in root clauses. In Mainland Scandinavian, this distribution is rather strictly limited to the latter context. The starting point is that the V3-pattern-triggering så is the ‘general adverbial resumptive’ in copy-left dislocation. In copy-left dislocation, an agreeing resumptive item causes a similar V3 pattern, where the adverbial spell-outs of the resumptive are partially interchangeable with så. Three hypotheses are considered. Firstly, så may have become fully generalised resumptive being interchangeable with all spell-outs. Secondly, the distribution could include all initial elements, also wh-phrases and negation markers, that are not pure operators. Finally, the paper suggests that the phenomenon is partially prosodic, and så satisfies a preference of having an anacrusis in the prosodic constituent including the finite verb.
