Analysing the imageries prevalent among the citizens of the young Turkish Republic in the post-Catastrophe Smyrna/Izmir, this article aims to shed light on the reflections of the destruction, forced migration, and economic provincialization of the ethnically-cleansed city. Aside from regular newspaper reports, travelogues and other popular literature accounts produced by local Muslims also recounted the haunting character of the ravaged region. The common word ‘loss’ in these post-Catastrophe narratives indicates what is apprehended by the imagery and discourse of mourning, trauma, sadness, and nostalgia from the victors’ perspective.
This paper demonstrates tensions between national environmental policies and international free trade rules and traces business reactions to environmentalism through a study of the Can War, a controversy over a Danish ban on beverage cans from 1970 to 2002. At its core was a conflict between Denmark and the European Economic Community (EEC, later the European Union, EU) over free trade versus environmental objectives. This study of the Can War demonstrates how environmental concerns were entangled with national and economic interests, but also how brewers, retailers, and packaging producers used environmental and economic arguments in pragmatic ways and adapted to changing political and economic environments. Thus, the paper adds to the literature on the formative years of environmental politics, with a focus on business interests and a conflict between a nation-state and the EEC in a period when environmental concerns gained political momentum yet remained contested in a system based on free trade. This study also adds to the literature on waste-handling by demonstrating how the Danish return system changed from one based on reuse to one based on recycling; it further shows how beverage cans went from banned to uncontested, everyday objects. Through a comparison with Sweden, the case shows how national businesses influenced the design of new deposit and return systems for single-use packaging, wherein refillable glass bottles became marginalized. Overall, the study offers an understanding of the intricate relationships between environmental policies, business interests, consumer habits, and competing container materials, with aluminum as the winner.
Despite the central role of language teacher educators (LTEs) in contributing to the development of language teachers in higher education and non-higher education contexts, there is a lack of theoretical and empirical work on their professional lives. One such area that remains largely unexplored concerns the psychology of LTEs. This paper argues for the need to embrace a research program that systematically investigates aspects of LTE psychology in the face of the unique demands, challenges, and pressures this professional group needs to navigate in their complex situated reality. We first position LTEs as key agents in the educational enterprise and go on to problematize the current state of scholarship on this under-researched population in universities, schools, and other practical settings. We then present an empirically grounded discussion to justify why a more explicit focus on LTE psychology is essential, followed by a brief review of what is already known in this respect. In what follows, we outline several key directions future empirical work might take to generate a more in-depth and holistic account of LTE psychology. Overall, this paper portrays LTE psychology as a promising but under-explored area which merits particular attention in its own right.
An isolated Leidenfrost droplet levitating over its own vapour above a superheated flat substrate is considered theoretically, the superheating for water being up to several hundred degrees above the boiling temperature. The focus is on the limit of small, practically spherical droplets of several tens of micrometres or less. This may occur when the liquid is sprayed over a hot substrate, or just be a late life stage of an initially large Leidenfrost droplet. A rigorous numerically assisted analysis is carried out within verifiable assumptions such as quasi-stationarities and small Reynolds/Péclet numbers. It is considered that the droplet is surrounded by its pure vapour. Simple formulae approximating our numerical data for the forces and evaporation rates are preliminarily obtained, all respecting the asymptotic behaviours (also investigated) in the limits of small and large levitation heights. They are subsequently used within a system of ordinary differential equations to study the droplet dynamics and take-off (drastic height increase as the droplet vapourises). A previously known quasi-stationary inverse-square-root law for the droplet height as a function of its radius (at the root of the take-off) is recovered, although we point out different prefactors in the two limits. Deviations of a dynamic nature therefrom are uncovered as the droplet radius further decreases due to evaporation, improving the agreement with experiment. Furthermore, we reveal that, if initially large enough, the droplets vanish at a universal finite height (just dependent on the superheat and fluid properties). Scalings in various distinguished cases are obtained along the way.
An exact solution is developed for bubble-induced acoustic microstreaming in the case of a gas bubble undergoing asymmetric oscillations. The modelling is based on the decomposition of the solenoidal, first- and second-order, vorticity fields into poloidal and toroidal components. The result is valid for small-amplitude bubble oscillations without restriction on the size of the viscous boundary layer $(2\nu /\omega )^{1/2}$ in comparison to the bubble radius. The non-spherical distortions of the bubble interface are decomposed over the set of orthonormal spherical harmonics $Y_{n}^{m}(\theta , \phi )$ of degree $n$ and order $m$. The present theory describes the steady flow produced by the non-spherical oscillations $(n,\pm m)$ that occur at a frequency different from that of the spherical oscillation, as in the case of a parametrically excited surface oscillation. The three-dimensional aspect of the streaming pattern is revealed as well as the particular flow signatures associated with different asymmetric oscillations.
The promotion of menstrual health and hygiene globally, especially in lower-middle-income countries (LMICs), is a major public health imperative. The primary study objective was to ascertain the change in the patterns of menstrual hygiene practices and their sociodemographic determinants amongst adolescent girls and young women in India. The present study analyses data from the Indian National Family and Health Survey (NFHS), round 4 (2015–2016) and round 5 (2019–21). Women in the age group 15–24 years (n = 241,180) were interviewed regarding their menstrual hygiene practices. The proportion of women using sanitary napkins as absorbent during menstruation increased from 41.8% (NFHS-4) to 64.1% (NFHS-5), with more than six in ten adolescent girls and young women in India using sanitary pads during menses, although the socioeconomically vulnerable more likely to lack access. The higher age group (20–24 years), rural residence, lower wealth quintile, absence of schooling, absence of flush toilets, and lack of exposure to media were factors that were independently associated with the use of cloth as menstrual absorbent. Vaginal discharge was reportedly higher among women using unhygienic products, however, on adjusted analyses, no statistically significant association was observed with the type of absorbent used. The transition from cloth to sanitary pads has nearly doubled on average in the states implementing free and subsidised government pad distribution schemes during the same period.
Oscillatory flows induced by a monochromatic forcing frequency $\omega$ close to a planar surface are present in many applications involving fluid–matter interaction such as ultrasound, vibrational spectra by microscopic pulsating cantilevers, nanoparticle oscillatory magnetometry, quartz crystal microbalance and more. Numerical solution of these flows using standard time-stepping solvers in finite domains present important drawbacks. First, hydrodynamic finite-size effects scale as $1/L_{\parallel }^2$ close to the surface and extend several times the penetration length $\delta \sim \omega ^{-1/2}$ in the normal $z$ direction and second, they demand rather long transient times $O(L_z^2)$ to allow vorticity to diffuse over the computational domain. We present a new frequency-based scheme for doubly periodic (DP) domains in free or confined spaces which uses spectral-accurate solvers based on fast Fourier transform in the periodic $(xy)$ plane and Chebyshev polynomials in the aperiodic $z$ direction. Following the ideas developed for the steady Stokes solver (Hashemi et al. J. Chem. Phys. vol. 158, 2023, p. 154101), the computational system is decomposed into an ‘inner’ domain (where forces are imposed) and an outer domain (where the flow is solved analytically using plane-wave expansions). Matching conditions leads to a solvable boundary value problem. Solving the equations in the frequency domain using complex phasor fields avoids time-stepping and permits a strong reduction in computational time. The spectral scheme is validated against analytical results for mutual and self-mobility tensors, including the in-plane Fourier transform of the Green function. Hydrodynamic couplings are investigated as a function of the periodic lattice length. Applications are finally discussed.
Cinq générations doivent actuellement cohabiter sur le marché du travail, ce qui peut entraîner plusieurs bénéfices, mais également un risque de tensions et de conflits susceptibles de nuire à la collaboration des équipes de travail et à la santé des personnes vieillissantes. La coopération intergénérationnelle au travail (CIT) a été relevée dans la littérature comme une avenue intéressante pour diminuer le risque de conflits intergénérationnels, mais elle demeure peu concrètement définie. Cette étude vise à proposer une définition opérationnelle du concept de coopération intergénérationnelle au travail à l’aide de la méthode d’analyse de Walker and Avant (2019). Quarante-huit manuscrits ont été répertoriés, permettant d’identifier huit attributs caractérisant la CIT, sept antécédents et six conséquents du concept. Cette étude fait ressortir le rôle des différents acteurs dans la CIT, met en lumière les bénéfices de la CIT et permet de considérer son rôle en prévention des lésions professionnelles.
Potassium is an essential macronutrient required for plant growth and development. Over the recent decade, an important signalling role of K+ has emerged. Here, we discuss some aspects of such signalling at the various levels of plant functional organisation. The topic covered include: (1) mechanisms of long-distant K+ transport in the xylem and phloem and the molecular identity and regulation of K+ loading and unloading into plant vasculature; (2) essentiality and physiological roles of K+ cycling between shoots and roots; (3) plant sensing and signalling of low K+; (4) maintenance of K+ homeostasis at the cellular level; (5) stress-induced modulation of cytosolic K+ as a signal in plant adaptive responses to hostile environment; (6) stress-specific K+ “signatures” and mechanisms of their decoding by regulation of purine metabolism and H+-ATPase activity; (7) cytosolic K+ loss as a metabolic switch and a regulator of autophagy; and (8) vacuolar K+ transport and sensing.
Recent experiments aiming to measure phenomena predicted by strong-field quantum electrodynamics (SFQED) have done so by colliding relativistic electron beams and high-power lasers. In such experiments, measurements of collision parameters are not always feasible. However, precise knowledge of these parameters is required to accurately test SFQED.
Here, we present a novel Bayesian inference procedure that infers collision parameters that could not be measured on-shot. This procedure is applicable to all-optical non-linear Compton scattering experiments investigating radiation reaction. The framework allows multiple diagnostics to be combined self-consistently and facilitates the inclusion of known information pertaining to the collision parameters. Using this Bayesian analysis, the relative validity of the classical, quantum-continuous and quantum-stochastic models of radiation reaction was compared for several test cases, which demonstrates the accuracy and model selection capability of the framework and highlight its robustness if the experimental values of fixed parameters differ from their values in the models.
Women legislators face a variety of gendered barriers both outside and inside the legislature. Yet, little previous scholarship has quantitatively examined whether legislative insiders are biased against women and their accomplishments. We explore a new potential explanation for gender inequity in legislatures: that women in office may get less credit than men for similar achievements. If legislative insiders systematically undervalue women’s work, women will have a harder time gaining influence within the chamber; alternatively, those working in and with the legislature may be uniquely aware of the effort that goes into representational activities and can observe the work that women perform firsthand. To examine this question, we combine elite evaluations of legislators from the North Carolina General Assembly with data on committee assignments, legislative effectiveness, electoral performance, and more. We find little systematic evidence that women legislators’ accomplishments are valued less than those of the men with whom they serve.
This paper focuses on the discursive connection between the notion of autonomy and the ageing-in-place policy approach, in a context of population aging and budgetary restraint. We argue that these central elements of the policy discourse on ageing represent a governance strategy that defines ageing in place as the prevailing standard for ageing well. Through an analysis of ageing policy documents released by the Québécois government between 2012 and 2023, this paper shows a disconnect between national policy frameworks and the reality of ageing in place. The issue of ageing in place is strongly bound up with the idea of autonomy, which is mainly expressed in terms of responsibility and freedom of choice, while its implementation overlooks the social structural determinants of individual autonomy and their impact on older people’s opportunities and processes of ageing in place.
A stochastic wavevector approach is formulated to accurately represent compressible turbulence subject to rapid deformations. This approach is inspired by the incompressible particle representation model of Kassinos & Reynolds (1994), and preserves the exact nature of compressible rapid distortion theory (RDT). The adoption of a stochastic – rather than Fourier – perspective simplifies the transformation of statistics to physical space and serves as a starting point for the development of practical turbulence models. We assume small density fluctuations and isentropic flow to obtain a transport equation for the pressure fluctuation. This results in four fewer transport equations compared with the compressible RDT model of Yu & Girimaji (Phys. Fluids, vol. 19, 2007, 041702). The final formulation is closed in spectral space and only requires numerical approximation for the transformation integrals. The use of Monte Carlo for unit wavevector integration motivates the representation of the moments as stochastic variables. Consistency between the Fourier and stochastic representation is demonstrated by showing equivalency between the evolution equations for the velocity spectrum tensor in both representations. Sample clustering with respect to orientation allows for different techniques to be used for the wavevector magnitude integration. The performance of the stochastic model is evaluated for axially compressed turbulence, serving as a simplified model for shock–turbulence interaction, and is compared with linear interaction approximations and direct numerical simulation (DNS). Pure and compressed sheared turbulence at different distortion Mach numbers are also computed and compared with RDT/DNS data. Finally, two additional deformations are applied and compared with solenoidal and pressure-released limits to demonstrate the modelling capability for generic rapid deformations.
Notre société segmentée par l’âge offre peu de possibilités d’interactions intergénérationnelles authentiques. Cela contribue aux stéréotypes et préjugés envers les personnes de tous âges, particulièrement les adultes aînés. Pour favoriser une société plus inclusive et lutter contre l’âgisme, un changement de paradigme sociétal devient nécessaire. À partir d’une recherche basée sur la conception et l’apprentissage intergénérationnel, nous avons cherché à mieux caractériser ces apprentissages afin de développer des formations spécifiques pour les appuyer. Basé sur un questionnaire préliminaire (n=79), nous avons conçu un atelier pilote (français/anglais) avec huit adultes aînées et huit jeunes adultes au cours duquel les participants ont dû réaliser en binôme une vidéo sur TikTok. Nos résultats indiquent que l’apprentissage intergénérationnel doit se fonder sur une pédagogie active, les activités et les objectifs pédagogiques doivent être multiples pour être réalisées en binômes intergénérationnels, le format doit permettre de développer une relation de confiance et l’évaluation doit être personnelle.
Kawasaki disease is a leading cause of acquired heart disease in children in the developed world, characterised by acute systemic vasculitis, with a complex aetiology that remains poorly understood. Recent studies have highlighted the potential anti-inflammatory effects of Interleukin-35 in various proinflammatory and cardiovascular conditions. However, the relationship between Interleukin-35 gene polymorphisms and Kawasaki disease susceptibility, particularly in Chinese children, has not been well-explored.
In this study, we investigated the association between five Interleukin-35 single-nucleotide polymorphisms—rs2243115, rs2243123, rs583911, rs353698, and rs2302164—and Kawasaki disease in a cohort of Chinese children. A total of ninety-four Kawasaki disease patients and one hundred healthy controls were enrolled, with the Kawasaki disease patients further divided into subgroups based on the presence or absence of coronary artery lesions and incomplete or complete Kawasaki disease. Genotyping of Interleukin-35 polymorphisms was performed using the MassARRAY system.
The results showed the GT + GG genotypes and G allele of rs2243115 (T > G) were significantly more prevalent in Kawasaki disease patients with coronary artery lesions than in those without coronary artery lesions, suggesting a possible association with the development of coronary artery lesions. Additionally, the G allele of rs353698 (A > G) was more frequently observed in the incomplete Kawasaki disease group compared to the complete Kawasaki disease group, suggesting a possible association with the risk of incomplete Kawasaki disease.
Travelling wave charges lying on the insulating walls of an electrolyte-filled capillary give rise to oscillatory modes which vanish when averaged over the period of oscillation. They also give rise to a zero mode (a unidirectional, time-independent velocity component) which does not vanish. The latter is a nonlinear effect caused by continuous symmetry breaking due to the quadratic nonlinearity associated with the electric body force in the time-dependent Stokes equations. In this paper, we provide a unified view of the effects arising in boundary-driven electrokinetic flows (travelling wave electroosmosis) and establish the universal behaviour exhibited by the observables. We show that the incipient velocity profiles are self-similar implying that those obtained with a single experimental configuration can be employed again to attain further insights without the need of repeating the experiment. Certain results from the literature are recovered as special cases of our formulation and we resolve certain paradoxes having appeared in the past. We present simple theoretical expressions, depending on a single-fit parameter, that reproduce these profiles, which could thus provide a rapid test of consistency between our theory and future experiment. The effect becomes more pronounced when reducing the transverse dimension of the system, relative to the velocity direction, and increasing the excitation wavelength, and can therefore be employed for unidirectional transport of electrolytes in thin and long capillaries. General relations, expressing the zero mode velocity in terms of the electric potential and the geometry of the system only, can thus be easily adapted to alternative experimental settings.
The duration of undiagnosed or untreated bipolar disorder (DUBD) has become a focus of research interest. However, its relationship with clinical characteristics and outcomes remains poorly understood.
Aims
The objective of this systematic review and meta-analysis was to examine DUBD and explore its relationships with clinical characteristics and outcomes in bipolar disorder.
Methods
We conducted a systematic search of the literature to identify studies reporting on DUBD and its relationships with clinical characteristics and outcomes including frequency of relapse into mood episodes, severity and persistence of mood symptoms, functional and cognitive measures, suicidality, hospital admission rate, and comorbidities such as substance use disorders.
Results
Thirty articles met inclusion criteria for the systematic review, and 23 studies were included in the three different sets of meta-analyses. The pooled mean DUBD across all studies was 9.10 years. Early onset, depression as the polarity of the first mood episode, lifetime suicide attempts, comorbid anxiety and alcohol use disorders, and family history of bipolar disorder were associated with significantly longer DUBD, whereas diagnosis of bipolar I disorder and lifetime psychotic symptoms were associated with shorter DUBD. Studies that investigated outcomes subsequent to the diagnosis of bipolar disorder yielded conflicting results.
Conclusion
DUBD may be associated with certain adverse outcomes. This association indicates the importance of adopting a more comprehensive approach to assessing mood disorders, with an emphasis on prioritising early screening for bipolar disorder. The significant heterogeneity among included studies suggests a need for improved methodological rigour in future research.
