The Recovery and Resilience Facility reflects the generalisation of spending conditionality and the economisation of the rule of law in EU governance. The RRF performance-based approach also applies to measures related to rule of law protection, meaning that recovery funds can only be disbursed as long as the related conditions are met. While the academic literature has already highlighted the difficulty of applying performance frameworks to values, this article assesses how the RRF performance-based approach integrates the safeguard of the rule of law, based on a comparative study of the Slovak, Hungarian and Polish plans. Rule of law protection is set as a priority in the RRF. Yet, the economic and financial framing – in line with New Public Management and neoliberal governmentality – limits the potential impact of rule of law reforms. Overall, the effectiveness of rule-of-law spending conditionality depends more on the features of the performance regime and the attitude of political actors than the degree of financial pressure.
Amphibious unmanned vehicles promise next-generation water-based missions by eliminating the need for multiple vehicles to traverse water and air separately. Existing research-grade quadrotors can navigate in water and air and cross the water–air boundary, but it remains unclear how their transition is affected by rotor kinematics and geometry. We present here experimental results from isolated small rotors (diameters $\sim 10\,\mathrm{cm}$) dynamically transitioning from water to air. We discovered that rotors experience an abrupt change in frequency, lift and torque before reaching the interface, and the change is linked to the surface depression caused by a free surface vortex. We explored how the surface dynamics are affected by advance ratio, rotor diameter, number of rotor blades and input throttle. Free surface vortices above rotating objects have been studied in the context of unbaffled stirred tanks, but not in the field of small amphibious rotorcraft. We show that existing free surface vortex models can be adapted to explain water-to-air rotor performance. A better understanding of water–air rotor transitions helps to (i) assess the amphibious capability of existing aerial rotors, and (ii) suggest efficient water–air transition strategies for next-generation amphibious vehicles.
Accumulating evidence suggests that stress, social relationships, and sex/gender differences in brain function, particularly of the orbitofrontal cortex (OFC), may drive problematic alcohol use. How these factors interact to effect alcohol use, and if they do so differently in men and women, has yet to be explored.
Methods
Using a subsample of the publicly available Human Connectome Project data consisting of young adults with problematic alcohol use (N = 491; 41.75% women, ≥1 symptom of alcohol abuse/dependence), we used a moderated moderation approach to test whether perceived stress and sex/gender moderated the effect of a multidimensional measure of social relationship quality on drinking levels. We subsequently tested whether OFC function moderated these effects.
Results
We found that in women, higher friendship and companionship had a protective effect on drinking levels, particularly for women under high stress. In contrast, in men, higher friendship and companionship were linked to increased drinking levels under stress. Preliminary evidence suggested that this effect in men was driven by a subgroup of men with higher OFC reactivity to negative emotional faces.
Conclusions
Our findings suggest that women benefit from friendship and companionship as a form of stress-relief in the context of problematic drinking, whereas men do not, supporting the need of interventions that facilitate emotionally supportive, pro-recovery social environments particularly in men. Preliminary evidence further suggests a role of emotional dysregulation in men. Overall, our findings support the importance of developing sex/gender and neurobiologically informed interventions that target stress-related alcohol use.
The value of people’s unique lived experience of mental illness (including psychosis), professional treatment and recovery as a valid form of knowledge remains relatively unexplored and under-utilised by mental health professionals, policy makers and by those seeking help. Mutual peer support remains a largely untapped resource, often ignored and distanced from mainstream services. In this reflective perspective article, I share my own experiences as a service user, spouse, close relative and brother-in-law and also as someone who worked for many years in mutual peer support and in the area of recovery. I reflect on the findings of my doctoral narrative research which focused on the role played by Grow Mental Health, Ireland’s largest network of mutual peer support groups, in recovery from a wide range of diagnoses. The main finding from this research suggested that recovery can be experienced as a re-enchantment with life and that mental illness can act as a gateway to mental health rather than be experienced as a form of (often life-long) disability. In the discussion I try and envisage what a recovery oriented mental health system might look like, and what changes would need to be introduced. Despite such a long personal history of dealing with mental illness and witnessing many different levels of recovery, I still have much to learn about mental illness and recovery. I also welcome many recent changes made within the system and indeed this special edition of the journal.
We simplify our lives by learning from others. I focus on instances where we learn from our peers by receiving evidence that they have evidence for a hypothesis. I refer to this type of learning as learning from others’ evidence. I exclusively consider cases where we do not learn what the other agent’s evidence is; we only receive evidence that such evidence exists. I approach learning from others’ evidence by exploring the following slogan, popular in epistemology:
EEE-Slogan “[E]vidence of evidence is evidence. More carefully, evidence that there is evidence for h is evidence for h” (Feldman 2007: 208; notation adjusted).
I am interested in the limitations of the slogan, focus on the impact of non-epistemic values on it, and argue for the following main thesis:
Non-Epistemic Values in the EEE-Slogan: There are cases in which we cannot (adequately) apply the EEE-Slogan due to the differing non-epistemic values between us and our peers.
In arguing for the thesis, I draw on and expand insights from the philosophy of science. There are instances where our peers’ reasoning, commitments, and evidence (see Douglas 2000) are not rationally acceptable to us due to differences in non-epistemic values. Building on this, I contend that in such cases, we cannot (adequately) apply the slogan.
Amid intensifying geopolitical competition and accelerating climate commitments, China’s rare earth elements (REE) sector has emerged as a strategic asset and a site of political contestation. While existing accounts emphasize China’s dominance through central control, this article develops the concept of “fractured extraction” to show how REE governance is mediated by uneven, multi-scalar negotiations among central authorities, provincial governments, municipal actors and firms. Drawing on historical analysis and provincial case studies from Inner Mongolia, Jiangxi and Sichuan, we argue that China’s REE governance is marked by cycles of alignment and divergence, where central mandates around environmental reform, industrial upgrading and resource consolidation are selectively implemented, reinterpreted or resisted by subnational actors pursuing local development goals. This dynamic reflects not fragmentation or coherence but fracture: a provisional, relational mode of governance that persists across China’s evolving extractive landscape. We identify four interrelated processes – innovation, upgrading, financialization and formalization – through which fractured extraction materializes to develop a framework for understanding the politics of green industrialization and strategic resource governance that foregrounds subnational actors and the contested nature of China’s low-carbon transition.
Atrial septal defect is commonly considered a minor CHD, but morbidity and mortality are higher compared to the background population. Maternal pre-eclampsia is associated with CHD in the offspring in large registry-based studies. However, the association between pre-eclampsia and atrial septal defects might be subject to detection bias, as many atrial septal defects are asymptomatic or might remain undiagnosed until late in life.
Objectives:
We investigated the association between maternal pre-eclampsia and the risk of atrial septal defects in a population-based cohort of neonates examined with echocardiography.
Materials and methods:
Neonates included in the Copenhagen Baby Heart Study, who were examined using transthoracic echocardiography within 30 days of birth, were systematically assessed for atrial septal defects and patent foramen ovale using a standardised algorithm. Using log-linear binomial regression and polytomous logistic regression, we compared the risk of atrial septal defects in neonates exposed to maternal pre-eclampsia with the risk in neonates not exposed to pre-eclampsia.
Results:
Our study cohort included 12,354 neonates (mean age, 11 days), including 462 exposed to maternal pre-eclampsia. Atrial septal defect was found in 5.9% (n = 732) of the study cohort and compared with unexposed neonates, neonates exposed to maternal pre-eclampsia had a modestly increased risk of atrial septal defects (adjusted risk ratio 1.19, 95% confidence interval 0.83, 1.64). Estimates were robust to various exclusions in sensitivity analyses.
Conclusion:
There appears to be an association between maternal pre-eclampsia and atrial septal defect in the neonate in a population-based cohort of neonates.
One of the natural problems of operational semantics is to characterise the relationship between eager and lazy evaluation. In the context of $\lambda$-calculus, this is expressed by the classic theorem that call-by-value evaluation of a program to (weak-head) normal form can always be simulated by a call-by-name evaluation. While the statement and intuition behind it are simple and clear, naive attempts at proof famously fail: the result is usually established as a consequence of the more complex standardisation theorem. In this work, we develop and formalise a novel and lightweight inductive approach to tackle the problem of simulation between two semantics for a single calculus, but with different evaluation orders. We exercise our method on the classic call-by-value and call-by-name example and report on methodological takeaways suggested by our approach, in particular what effect the flavour of semantics chosen has on the proof.
Distinguishing viral versus bacterial lower respiratory tract infection (LRTI) is challenging. We previously developed a rapid, host response-based test (Biomeme HR-B/V assay) using peripheral blood samples to identify viral versus bacterial infection. We assessed the performance of this assay when using nasopharyngeal (NP) samples.
Methods:
Patients with LRTI were enrolled, and a NP swab sample was run using the HR-B/V assay (assessing 24 gene targets) on the FranklinTM platform. The performance of the prior classifier at identifying viral versus bacterial infection was assessed. A novel predictive model was generated for NP samples using the same 24 targets. Results were validated using external datasets with nasal/NP RNA sequence data.
Results:
Nineteen patients (median age 62 years, 52.1% male) were included. When using the prior HR-B/V classifier on NP samples of 19 patients with LRTI (12 viral, 7 bacterial), the area under the receiver operator curve (AUC) for viral versus bacterial infection was 0.786 (0.524–1), with accuracy 0.79 (95% CI 0.57–0.91), positive percent agreement (PPA) 0.43 (95% CI 0.16–0.75), and negative percent agreement (NPA) 1.00 (95% CI 0.76–1). The novel model had AUC 0.881 (95% CI 0.726–1), accuracy 0.84 (95% CI 0.62–0.94), PPA 0.86 (95% CI 0.49–0.97), and NPA 0.83 (95% CI 0.55–0.95) for bacterial infection. Validation in two external datasets showed AUC of 0.932 (95% CI 0.90–0.96) and 0.915 (95% CI 0.88–0.95).
Conclusions:
We show that host response in the nasopharynx can distinguish viral versus bacterial LRTI. These findings need to be replicated in larger cohorts with diverse LRTI etiologies.
Astrotheology, the theological engagement with astrobiology and the possibility of extraterrestrial life, has primarily focused on the compatibility of scientific and religious beliefs. However, this article argues that probability and risk assessments play a larger role in the discussion than is commonly recognised, and there is need to learn from the rigour with which natural theological arguments have been evaluated. For instance, the relative urgency and style of astrotheological discourse is affected by ideas of what sort of life is likely to be out there, if any. In this article, I analyse astrotheological risk assessments from the framework of decision theory, using the discussion over Pascal’s Wager as a comparison case. Arguments over the fittingness of creating other life forms are analysed through a comparison with fine-tuning design arguments. I argue that while theological engagement with astrobiology remains important, the justification of probability and risk assessments depends on disputed philosophical and theological assumptions. Examining the compatibility of theological systems and ideas about extraterrestrial life is important. However, fostering doubt about these probabilities is also a service that theology can do for astrobiological debates.
This paper examines the intersection of socio-legal research and activism through my ethnographic work with the Tulipas do Cerrado collective, a group of sex workers in Brazil. It explores the dynamics of knowledge production and the transformative potential of collaborative research that prioritises the reflections and experiences of marginalised communities while recognising the importance of legal expertise. Drawing on the concepts of ‘whoring the knowledge’ and ‘whoring the law’, the article highlights how sex workers reclaim their narratives and creatively navigate legal frameworks, demanding that researchers enhance both academic and activist relevance of their endeavours. First, I discuss relevant literature on ethnography within sex workers’ activism, introducing recent key studies on Brazilian sex work as examples of having the knowledge whored. Then, I detail the ethnographic approach employed in my research, which was inspired by the preceding three studies. Ultimately, the work analyses how reciprocal engagement between sex work activists and scholars is a consequence of a demand that researchers adopt a bolder and more creative way of thinking and living. Furthermore, from a socio-legal perspective, these exchanges present an opportunity to rethink the role of law within these communities and to foster concrete social transformation. I propose the concept of ‘whoring’ the law, suggesting that both activists and socio-legal scholars can identify and build new pathways for dealing with the law.
The integration of electro-osmotic effect to the underlying flow enhances solute dispersion precision in microfluidic systems, which is crucial for applications such as drug delivery and on-chip fluidic functionalities. We investigate, in this study, the solute dispersion characteristics of couple-stress fluids in a two-dimensional microchannel configuration under the combined effects of electro-osmotic actuation and applied pressure gradients. We consider both homogeneous and heterogeneous reactions in the present analysis. Couple-stress fluids, which account for additional stresses due to the presence of the microstructures in the fluids, offer a more accurate model to describe the rheological behaviour of biofluids. While previous studies have addressed longitudinal Gaussianity and transverse uniformity of solute distribution, we focus uniquely in this endeavour on longitudinal uniformity. Using Mei’s multiscale homogenisation technique, we solve a two-dimensional convection–diffusion model, extending it to third-order approximation to analyse the dispersion coefficient, concentration profiles, and variation rates of concentration within microchannel flow. Results show that forcing and couple-stress parameters enhance the gradients of the longitudinal variation rate, while boundary absorption reduces this variation rate near the walls. The couple-stress parameter exhibits dual behaviour: initially, it enhances solute dispersion, but beyond a certain value of couple-stress parameter $B_{cr}$ (which depends on forcing comparison and the Debye–Hückel parameter), it reduces dispersion. In the absence of pressure, solute distribution remains longitudinally uniform. However, as the pressure gradient increases, concentration levels drop sharply, and the distribution shifts to a parabolic profile, underscoring the significant influence of pressure on flow behaviour in electro-osmotic flow.
Although virtual reality (VR) programs are being developed by marginalized groups’, a systemic power imbalance still exists. Marginalized groups have a place in digital wellbeing and can lead initiatives to access resources that they desire. To better support these efforts and mobilize knowledge among marginalized stakeholders, we conducted a scoping review of the use of VR for wellbeing. Adopting an equity lens that considers the experiences of intersectional marginalization, our aim was to identify VR programs, their targets, outcomes and equity-related facilitators and barriers. In May 2023, we conducted a comprehensive literature search of MEDLINE, PsycINFO, Embase and Web of Science databases and grey literature for virtual reality and marginalized populations. Eligible research articles since the inception of the databases were those that met our predefined criteria of VR, marginalized populations and wellbeing. We included 38 studies and charted preregistered variables using narrative synthesis, descriptive statistics, and a logic model. The populations were often intersectionally marginalized--primarily individuals with disabilities, underrepresented sexualities and genders, and marginalized older individuals in high-income countries on Turtle Island (North America). The most common race categories were Black or African American (26%) and European or White (53%), but other sociodemographic characteristics were underreported. VR offered diverse support, including social, mental, physical and cultural. We report program outcomes for several subgroups; though heterogeneous, most studies reported improved wellbeing outcomes. VR’s flexibility created informal, flexible spaces, with peer support that contributed to mental and social wellbeing. Several factors could hinder marginalized groups’ ability to access and participate, such as the lack of free programs, data and program ownership, and intersectional data analyses. This topic reflects a growing literature, with half of the publications being in 2022 or 2023. Many of these studies have limitations like small sample sizes and a lack of mixed-methods or practical significance analyses. Moving forward, researchers should apply more open-access and inclusive practices in their designs and recruitment processes to widen equitable access to marginalized stakeholders. Nevertheless, many marginalized populations created VR programs and benefited from them, contributing to a rebalancing of power over wellbeing.
In 1910, Cunningham developed a heuristic expression to predict the drag on a slow-moving spherical particle in a gas; a drag that deviates from Stokes’ law when the particle’s size is comparable to the gas’s mean free path. More than a decade later, Millikan proposed a physical argument for correcting Cunningham’s work: the resulting expression is known today as the ‘Cunningham correction factor’. Despite his contribution, Millikan missed a simpler way to correct Cunningham’s expression, one that would have preserved its generality. In this article, this new, simpler form of the Cunningham correction factor is expanded to provide a predictive heuristic for non-spherical particles through the definition of a ‘correction tensor’. Its accuracy is tested against experiments and kinetic theory for the sphere, and solutions to the Boltzmann equation for a range of spheroids and an infinitesimally thin circular disc.
Sensory Over-Responsivity Disorder (SORD) is characterized by extreme sensitivity to everyday sensory input, which can interfere with children’s emotional, behavioral and social development. Despite growing interest, limited research has explored its developmental effects in the absence of other psychiatric diagnoses. This study investigated self-regulation and related clinical features in preschool children with SORD who did not meet diagnostic criteria for autism spectrum disorder, attention-deficit/hyperactivity disorder (ADHD), or obsessive-compulsive disorder. The sample included 15 children with SORD and 15 typically developing controls, matched by age and gender. Diagnoses were made using the Preschool Age Psychiatric Assessment, and comorbidities were excluded using Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood: Revised Edition criteria. Self-regulation was assessed through the Head-Toes-Knees-Shoulders-Revised task. While no significant differences were found in autistic traits, repetitive behaviors or executive functioning, children with SORD demonstrated significantly poorer self-regulation (p < .001). Poorer self-regulation was strongly associated with greater SORD severity, elevated ADHD symptoms, lower social interaction and increased emotional and sensory reactivity. These findings suggest that self-regulation difficulties are a core feature of SORD, even in the absence of comorbid psychiatric disorders. Early identification and interventions targeting self-regulation may help improve long-term outcomes for children affected by SORD.
Zaiwa (ISO 639-3 code: atb; Glottocode: zaiw1241) belongs to the Burmese branch of the Tibeto-Burman languages, sharing many common features with the Burmese and Achang languages of the same branch. It is primarily spoken by a subgroup of Jingpo people, who identify as ‘Zaiwa’. Beyond Zaiwa, the Jingpo people encompass four distinct subgroups, each conversing in unique linguistic variations, namely Jingpo (景颇), Langsu (浪速), Leqi (勒期), and Bola (波拉). Jingpo is distinctively affiliated with the Jingpo branch of the Tibeto-Burman languages, whereas the other three languages, including Zaiwa, are categorized within the Burmese branch (He, 2016). The majority of Zaiwa speakers are found in Luxi (潞西), Yingjiang (盈江), Longchuan (陇川), Ruili (瑞丽), Lianghe (梁河), and Wanding (畹町) counties within the Dehong Dai and Jingpo Autonomous Prefecture (德宏傣族景颇族自治州) of Yunnan province (云南省) as well as the Shan and Kachin states in Myanmar. Zaiwa is widely used in Zaiwa-dominant areas or communities with a significant Zaiwa presence. It is used not only in daily life contexts, such as among family members, villages, markets, and shops, but also in a range of social sectors, including in government and judicial offices, as well as on radio and broadcasting stations. Among the Jingpo languages, Zaiwa has the largest number of users. Individuals who speak Zaiwa often speak languages of other Jingpo subgroups in addition to Mandarin Chinese. Due to the extensive promotion and dissemination of Mandarin, particularly in educational and media contexts, Mandarin has emerged as the predominant second language for the youth within the community. Moreover, in neighboring regions or mixed communities where the Zaiwa subgroup is prominent, individuals from other ethnic groups such as the Achang, Han, Dai, and Lisu also frequently speak Zaiwa. According to the statistics from China’s Sixth National Population Census in 2010, the total population of the Jingpo ethnic group is approximately 140,000. There were over 80,000 Zaiwa speakers within China, constituting more than 60% of the total Jingpo ethnic population in the country (He, 2016). Scholars such as Xu and Xu (1984), Dai (1989), Kong (2001), Pan (2014), He (2016), Lu and Kong (2019), and Lu et al. (2025) have conducted studies on the phonetics of Zaiwa.
In many tourism-dependent islands, an acute imbalance between increasing demand for wastewater management and the capacity of existing sewage infrastructure represents an increased risk for ecosystems and population health. Given that locals may be opposed to increasing tourism taxes to fund investments in sewerage, promoting charitable giving among tourists may be an alternative to improve wastewater management in tourist destinations. Using a contingent valuation survey, this study assesses whether tourists are willing to donate to improve wastewater management in San Andres Island, Colombia. Split-sample treatments were implemented to examine the response of tourists' giving preferences to priming communications regarding the effects of poor wastewater management. Results indicate that tourists are willing to donate to improve local wastewater management. Our findings also provide useful insights about tourists' giving preferences to design effective charitable giving campaigns to improve wastewater management.
With this paper, I suggest focusing on diplo-scientific actors as a fruitful approach to study how certain actors have helped to shape international organisations through their diplomatic activities and scientific practices. Using the example of the Swedish medical physicist Rolf Sievert, I show how Sievert’s personality and preferences came to decisively shape the post-war trajectory of the International Commission on Radiation Protection (ICRP) and more broadly the international landscape of radiation protection. In the inter-war period, Sievert was engaged in the ICRP and its mother organisation, the International Radiological Congress (IRC), dealing with the interwoven questions of how to formulate international radiation standards and radiation protection initiatives. Following the Second World War, Sievert became concerned with the proliferation of nuclear technologies and the spread of radioactive fallout following nuclear test bombings. Because of this concern, Sievert set out to separate the ICRP from the IRC and form a new, independent group that could deal with the dangers of the new ‘Nuclear Age’. While Sievert was ultimately unsuccessful, his attempts would decisively change the purview and trajectory of the ICRP. This had large ramifications, as the ICRP continues to be the prime international organisation on radiological and medical radiation protection, formulating recommendations that are used by international, regional, national, and local groups, informing epistemic judgements on radiation research.
Supersonic turbulent channels subjected to sudden spanwise acceleration at initial friction Reynolds numbers of approximately 500 and different Mach numbers are studied through direct numerical simulations. The response to the spanwise acceleration creates a transient period where the flow exhibits three-dimensionality in the mean statistics. This enables a detailed study of the thermal transport and development of velocity transformations and Reynolds analogies for compressible turbulent flows in swept-like conditions. Extensions of velocity transformations to three-dimensional (3-D) flows demonstrate near-wall self-similarity of the velocity, providing evidence for Morkovin’s hypothesis in non-equilibrium conditions. A similarity solution for the spanwise velocity, valid during the initial transient, is also presented. During the transient, both the thermal fluctuations and turbulent kinetic energy (TKE) decrease, consistent with previous observations in incompressible flows (Lozano-Durán et al. 2020 J. Fluid Mech. 883, A20, Moin et al. 1990 Phys. Fluids A: Fluid Dyn. 2, 1846–1853). For sufficiently strong spanwise acceleration, $Q_{3}$$(+T',+v')$ and $Q_{1}$$(-T',-v')$ events become more significant than sweep and ejections across the channel, creating changes in sign in the velocity–temperature covariances. The temporal evolution of the orientation and sizes of the TKE and temperature-carrying structures is quantified through structure identification and spectra. Finally, the generalized Reynolds analogy (Zhang et al. 2012 Phys. Rev. Lett. 109, 054502) is derived for a transient 3-D flow, allowing predictions of the mean temperature from the velocity.
