This paper contributes to the emerging field of forest pedagogies by foregrounding mangroves as critical sites for learning with more-than-human entanglements in polluted worlds. Engaging with planetary strategies of corresponding, evidencing and circulating, we approach mangroves as complex, contested and vital ecotones. We explore how mangroves invite pedagogical attention to the lived realities of toxicity, urbanisation and forms of contamination in the emergence of the Anthropocene. We conceptualise mangroves as “unruly edges” that unsettle binary distinctions between forest and estuary, fresh and saline waters and call for an estimation, historisation and analyses of interspecies entanglements. This position grounds a critical pedagogical project of “riparian struggles,” fostering mutual learning among river-zone inhabitants across planetary contexts. Through a case study in the Guanabara Bay region of Rio de Janeiro, we present filmmaking as a threefold tactic that (1) situates mangrove struggles within broader historical geographies, (2) supports community-based and student learning with contaminated ecologies and (3) circulates tactics of mangrove struggles across academic, educational and public spheres. Ultimately, we propose mangroves as more-than-human classrooms where practices of habitability with toxicity can be cultivated, unsettling paradigms of ecological purity and expanding forest imaginaries within the field of Critical Forest Studies.
We investigate axisymmetric surfaces in Euclidean space that are stationary for the energy $E_\alpha=\int_\Sigma |p|^\alpha\, d\Sigma$. Using a phase plane analysis, we classify these surfaces under the assumption that they intersect the rotation axis orthogonally. We also provide applications of the maximum principle, characterizing closed stationary surfaces and compact stationary surfaces with circular boundary in the case $\alpha=-2$. Finally, we prove that helicoidal stationary surfaces must in fact be rotational surfaces.
English is the lingua franca not only for academia but also for almost all international infrastructures and global communications. It comes as no surprise, then, that the dominant and assumed normative voice in archaeology is standard British English (SBE) for narratives of various times and places. This language is ‘majoritarian’—by this we do not mean that it is spoken by most of humanity, but that it is the imposed ‘ideal’ others are measured against, and that is an issue. Categories, terms and ways of interpretation are all done from a privileged majoritarian position. These do not translate and are certainly not applicable in all the different places where archaeology takes place. This paper is the culmination of conversations that occurred during a Theoretical Archaeology Group conference session in 2023, with contributing authors having adapted their talks into a discussion format to keep the conversation on challenging language representation active within the discipline.
Industrial and organizational (I-O) psychology recognizes dozens of different constructs, including several individual differences, environmental variables, job attitudes, and work-related behaviors. It is, of course, necessary to retain a variety of constructs in order to adequately capture the complexities, subtleties, and diversity of work-related phenomena. But do the many constructs recognized by I-O psychologists all serve a useful purpose? Or has our field been too eager to welcome redundant, unnecessary constructs into the fold? And if I-O psychology has embraced too many unnecessary constructs, then what—if anything—should we do about it? In the current focal article, we first discuss when and why construct proliferation occurs. We then advance a nuanced perspective—one that asserts that construct proliferation is occasionally “good,” usually “bad,” largely inevitable, and often incentivized. We conclude by calling for a temporary moratorium on the introduction of new constructs into the field of I-O psychology, and we offer suggestions for how the field can address construct proliferation. We hope that the current article leads to a fruitful discussion of how to most effectively solve the construct proliferation dilemma.
Psychiatrists in resource-constrained Indian settings face profound ethical dilemmas when progressive mental health legislation conflicts with ground realities. The Mental Healthcare Act 2017 mandates care standards that are often unattainable given family abandonment, inadequate rehabilitation facilities and persistent stigma, particularly in rural areas. Early-career clinicians experience moral distress when choosing between legal compliance and patients’ best interests. This gap between rights-based frameworks and available resources creates systematic moral injury among providers. Addressing these challenges requires comprehensive ethics training, peer support mechanisms and coordinated community infrastructure development to protect both clinician well-being and patient outcomes.
A growing body of evidence finds that rural electrification reduces fertility, typically by expanding women’s opportunities outside the home and raising the opportunity cost of childbearing. We examine electrification in post-revolutionary rural Iran, where electricity expanded rapidly but female labor force participation remained low. Using a large panel of villages observed in the 1986, 1996, and 2006 censuses, we show that while Ordinary Least Squares estimates align with the broader literature in suggesting a negative association between electrification and fertility, instrumental variable estimates exploiting elevation-based variation reveal the opposite: villages with longer exposure to electricity experienced higher fertility. This positive effect is strongest in provinces with lower female labor force participation, indicating that the substitution channel emphasized in prior research was weak in the Iranian context. These findings highlight the importance of context in shaping demographic responses to infrastructure and suggest that electrification’s effects on fertility are not universally negative.
In France, HIV prevention measures including HIV testing, treatment, and uptake of pre-exposure prophylaxis (PrEP), have increased throughout the last decade. To analyse their impact, we performed a time series analysis of monthly HIV diagnoses reported via the national HIV surveillance database. In addition, we compared the timing of HIV promotional campaigns with monthly trends in HIV testing and PrEP initiation. From January 2012 to December 2022, new HIV diagnoses steadily decreased among men who have sex with men (MSM) born in France and heterosexuals born in France, whereas HIV diagnoses increased among MSM born abroad. HIV testing activity and PrEP use in France both steadily increased from 2014 to 2020, during which multiple campaigns targeting HIV testing and prevention occurred. The decline in HIV diagnoses among MSM born in France preceded the introduction of PrEP in 2016 and continued post-2016 without any acceleration in the rate of decline. Increased awareness of, access to and uptake of HIV prevention measures remain essential to progress towards HIV elimination in France, especially among MSM born abroad.
This inquiry explores how eco-phenomenology reveals our relational engagement with forests inspiring a philosophy of education nurturing an ethos of mystery useful to teacher education, and the unsettling and decolonising of Western settler views of a Canadian forest. Through eco-phenomenological descriptions and interpretations, immediate lived experiences in a forest reveal three concepts: the sylvan fringe, the clearing and the care structure. Respectively, the ontological, epistemological and axiological domains of poetism, as a philosophy of education consist of physis (presencing-absencing), poetic knowledge (known-unknown) and dwelling (care structure). The relationship between Critical Forest Studies (CFS) and teacher environmental education is furthered by considering currents in environmental education and programming. CFS and poetism each resonate with the holistic current of environmental education and are well suited to the systematic programming of environmental education in teacher education.
The Gaza war, which started on 7 October 2023 through the horrendous attack by Hamas on Israel, has caused a depressing measure of human suffering on all sides. As far as Israel’s use of force is concerned, this war also constitutes a challenging case for the application of the jus contra bellum. This chiefly arises from the genuine legal uncertainty concerning the applicability of the right of self-defence when an armed attack by a non-state organisation emanates from the territory of a state that has proven unable to prevent said armed attack. Arguably, the situation in the Gaza Strip on 7 October 2023 presents the rare variation of such an ‘unable host state scenario’ where the non-state armed attack (by Hamas) against a state (Israel) has originated from a territory (the Gaza Strip) destined for the realisation of the right to self-determination of a people (the Palestinian people). In such a case, the dilemmatic conflict that underlies the uncertainty about the applicability of the right of self-defence is between the legally protected interests of the state that is the victim of the armed attack and those of the ‘host people’ of the non-state attacker.
Leishmaniasis is a neglected parasitic disease responsible for significant morbidity and mortality. Currently, there is no vaccine approved for clinical use. Therefore, controlling infections in infected individuals depends on interventions to prevent infected female sand flies from biting humans, treatment of clinical infections or alternative treatment methods. This review focuses on the types of vaccine developed to control leishmaniasis and which vaccines have made it through to clinical trials. It also discusses the role CRISPR technology may play in improving vaccine candidates design.
This study aimed to evaluate the effectiveness of the SmartNav in detecting tip fold-over during cochlear implantation and to compare angular insertion depth measurements obtained via SmartNav and transorbital X-ray imaging.
Methods
This retrospective multicentre study included patients with normal cochlear anatomy, comprising 163 individuals and 213 ears who underwent cochlear implantation using Nucleus CI522 and CI622 systems at Gazi University Faculty of Medicine and Gaziantep City Hospital.
Results
Of the 213 cochlear implantations, tip fold-over was detected in 4 implantations (1.88 per cent) intra-operatively with SmartNav. One case (0.47 per cent) of tip fold-over was not detected by SmartNav and identified post-operatively through X-ray imaging. SmartNav showed a sensitivity of 80 per cent, specificity of 100 per cent. A strong correlation was found between SmartNav and X-ray angular insertion depth measurements (p < 0.001).
Conclusion
The SmartNav is a reliable tool for the intra-operative detection of tip fold-overand the assessment of angular insertion depth in patients with normal cochlear anatomy.
Mycobacterium lentiflavum is a rare, non-tuberculous mycobacterium (NTM) which is implicated in some cases of active, pulmonary non-tuberculous mycobacterial disease. The outbreak of NTM in nosocomial settings occasionally occurs and outbreak investigation with implementation of concurrent countermeasure is essential.
Design:
Outbreak investigation.
Setting:
A tertiary care medical center.
Patients and participants:
Hospitalized patients during the outbreak period.
Results:
In April 2024, a cluster of patients with Mycobacterium lentiflavum–positive sputum cultures, presumed to be due to nosocomial transmission, was identified at the study center. A retrospective review of cases dating back to February 2023 revealed 27 patients with M. lentiflavum infection whose isolates had initially not been speciated. According to the American Thoracic Society (ATS) criteria for diagnosing pulmonary non-tuberculous mycobacterial (NTM) disease, two of these patients met the criteria for active disease. Multi-locus sequence typing of 12 isolates demonstrated 100% clonality, indicating a common source. A concurrent outbreak investigation identified contaminated faucet aerators in hospital wards as the likely source of transmission. All faucet aerators and caps were manually cleaned and disinfected using liquid sodium hypochlorite, after which no further cases were detected.
Conclusion:
The present study described a nosocomial cluster of M. lentiflavum colonization and infections at a tertiary care center, with contaminated faucet aerators identified as the likely source. Prompt identification of such NTM clusters in healthcare settings is essential to initiate timely treatment and prevent further transmission.
We study the combined effects of natural convection and rotation on the dissolution of a solute in a solvent-filled circular cylinder. The density of the fluid increases with increasing concentration of the dissolved solute, and we model this using the Oberbeck–Boussinesq approximation. The underlying moving-boundary problem has been modelled by combining the Navier–Stokes equations with the advection–diffusion equation and a Stefan condition for the evolving solute–fluid interface. We use highly resolved numerical simulations to investigate the flow regimes, dissolution rates and mixing of the dissolved solute for $Sc = 1$, $Ra \in [10^5, 10^8]$ and $\varOmega \in [0, 2.5]$. In the absence of rotation and buoyancy, the distance of the interface from its initial position follows a square root relationship with time ($r_d \propto \sqrt {t}$), which ceases to exist at a later time due to the finite-size effect of the liquid domain. We then explore the rotation parameter, considering a range of rotation frequency – from smaller to larger, relative to the inverse of the buoyancy-induced time scale – and Rayleigh number. We show that the area of the dissolved solute varies nonlinearly with time depending on $Ra$ and $\varOmega$. The symmetry breaking of the interface is best described in terms of $Ra/\varOmega ^2$.
The rice (Oryza sativa L.)–wheat (Triticum aestivum L.) cropping system (RWCS), recognized as the world’s prime agricultural system, plays a pivotal role in global food security by providing employment for millions and ensuring a steady income, thereby serving as a cornerstone for farmers’ livelihoods and attracting numerous investors. However, the sustainability and efficiency of this critical system face momentous threats due to climate change, which affects both the quantity and quality of wheat and rice crops. Currently, the growth frequency of the RWCS has declined, principally due to evolving challenges such as weed infestation, delayed wheat sowing after rice harvest, soil salinity, and the prevalence of various diseases. Among these challenges, weeds pose a considerable threat to the cultivation of both rice and wheat. Seed germination, a crucial stage in the plant life cycle, is influenced by various factors, including dormancy, temperature, moisture, oxygen, and light. A comprehensive understanding of weed ecology is essential for identifying vulnerabilities that can be targeted for improved weed management. Population-based threshold models, including hydro-time and thermal time, provide insights into germination patterns, contributing to the overall fitness of weed species. The ability to predict species’ responses to climate change is paramount, and these models are effective in comprehending and controlling weed emergence behavior across diverse environments. Hence, this review paper emphasizes the reevaluation of current weed management practices, focusing on investigating ecologically sustainable approaches for efficient weed control.
In an era of accelerating ecological degradation, how might experimental art practices help audiences foster deeper, more empathetic engagement with the intelligence of living systems? This paper explores the potential of contemporary art, when aligned with ecological science, to reframe forest regeneration as a site of aesthetic and ethical inquiry — by regarding the forest as a primary composer within artistic and ecological frameworks. It asks: how might this approach underpin a novel form of “Critical Forest Pedagogy” capable of deepening our understanding of the collective natural intelligence of the living world and encouraging long-term conservation?
To test these ideas, a new art-science project, Forest Art Intelligence, was initiated, framing a regenerating forest as an evolving, living artwork. Because forests evolve through stages mediated by life, death, regeneration and human influence, those stages of growth can also be framed as “process art” — a practice that values each stage of an artwork’s transformation. Collectively therefore this approach proposes a form of art-led “Critical Forest Pedagogy” suited to engaging communities traditionally unaligned with conservation, while remaining relevant to ecologically cognate audiences. It further asks whether this framing might promote a rethinking of restrictive, human-centred definitions of intelligence that underpin generative AI.
Roll patterns on floating ice shelves have been suggested to arise from viscous buckling under compressive stresses. A model of this process is explored, allowing for a power-law fluid rheology for ice. Linear stability theory of uniformly compressing base flows confirms that buckling modes can be unstable over a range of intermediate wavelengths when gravity does not play a dominant role. The rate of compression of the base flow, however, ensures that linear perturbations have wavelengths that continually shorten with time. As a consequence, linear instability only ever arises over a certain window of time $t$, and its strength can be characterised by finding the net amplification factor a buckling mode acquires for $t\to \infty$, beginning from a given initial wavenumber. Bi-axial compression, in which sideways straining flow is introduced to prevent the thickening of the base flow, is found to be more unstable than purely two-dimensional (or uni-axial) compression. Shear-thinning enhances the degree of instability in both uni-axial and bi-axial flow. The implications of the theoretical results for the glaciological problem are discussed.
Panel data often contain stayers and slow movers. The literature proposes an estimator for the average partial effects (APEs) for this setting without a formal theory. The literature is also silent about inference in the presence of stayers and many slow movers. We contribute to this state of the art. First, we develop an asymptotic theory to guarantee that such an estimator is consistent in the presence of stayers and slow movers. Second, we propose its standard error. Third, we relax the existing assumption to allow for “many” slow movers. Fourth, we generalize the existing estimator. Fifth, we establish that this generalized estimator can achieve larger extents of bias reduction and hence faster convergence rates. Simulation studies demonstrate that the conventional 95% confidence interval covers the true value of the APE with 37%–93% frequencies whereas our proposed one achieves 93%–96% coverage frequencies. Using the U.S. Panel Study of Income Dynamics, we find that estimates of the marginal propensity to consume based on our generalized estimator remarkably differ in values from those of the existing estimators. Moreover, the generalized estimator achieves more than three times as small standard errors as those of the existing robust estimator.
UK food system transformation is urgently needed, but to date, minimal research has investigated ‘blue foods’ probably because they are ethically nuanced. There exists a paradox whereby materially deprived communities should be eating more fish to meet nutritional requirements, yet there is a global ‘red flag’ around global overfishing. New collaborative and creative solutions are, therefore, needed to tackle such food system inequities. By working together, all voices can be equally heard when decisions are being made to improve the system. Similarly, innovation and disruption of established supply chains will enable better access to healthy, affordable and tasty food that will support better nutrition, health and wellbeing. This review paper will present a critique of the ‘The Plymouth Fish Finger’ as a collaborative social innovation case study. Part of the FoodSEqual research project, this exploratory pilot project championed ‘co-production’ approaches to achieve multiple (potential) impacts. This review will critically explore how this social innovation case study has exemplified the complex interplay between factors driving distortions in access to and availability of fish within the local food system. Through collaborative multi-stakeholder (transdisciplinary) processes, using participatory creative methods, new strategies and recommendations for research, practice, action and policy are informed, all of which offer great potential for progressive and transformative systemic (blue) food system change.
Tropical glaciers have undergone significant shrinkage or complete disappearance due to climate change. Based on geodetic observations and remote sensing data, this study presents a comprehensive chronology of the extinction of Carihuairazo Ice Cap (Kari-Huayra-Razu in Quichua), located in the Ecuadorian Andes, from 1956 to 2020. The cumulative glacier mass balance over the 1956–2020 period was − 31.40 m w.e. (−0.49 ± 0.04 m w.e. a−1), determined over three periods of ice loss 1956–2005, 2005–2011, and 2011–2020, during which the annual average mass balance was − 0.41, − 0.77 and − 0.75 m w.e. a−1, respectively. The loss of glacier mass led to total glacier shrinkage, with a pronounced acceleration between 1978 and 1986, after which the glaciers retreated rapidly and disappeared by 2024. The ice cap experienced an average annual area loss of 3 % a−1 since the 1980s, a trend two times as high as that reported for the Antisana Ice Cap during a similar period.
