This paper examines how public health promotion in colonial Australia figures the maternal body as an instrument for the production of whiteness for the perpetuation of the colonial state. In the context of a paradox between the institutional valuing of motherhood and institutional practices of systemic child removal and violence against women and mothers, I argue that public health promotion should be understood as a mechanism for the production of the white maternal body. I first establish the coloniality of public health promotion, arguing that its purpose is the production of bodies for the sake of colonial futurity, and that it so functions as a racializing code. Next, I offer a genealogical account in which the emergence of maternal subjectivity is shown to be the product of the colonial struggle for power; the white maternal body is thus produced through a schema of colonial mechanisms, among them the naturalization of sex, the feminization of the domestic sphere, the institutional establishment of the nuclear, heteroromantic family, and the British colonial notion of private property. I finally analyze how the white maternal body is subsequently materialized through the body’s own existential-temporal capacity for habituation.
Capacity assessments under the Mental Capacity Act 2005 (MCA) are a routine part of daily clinical practice in England and Wales. One element of these is the role of insight within the MCA’s capacity criteria. This article focuses on the issue of insight and capacity in a recent Court of Protection judgment, discussing how to assess insight in clinical practice and elucidating key issues regarding the role and assessment of insight within capacity assessments. The article includes a 10-point checklist for capacity assessments that was presented in the judgment, and a discussion of insight assessments that can guide documentation and be implemented in clinical practice.
This parallel randomised controlled trial examined the effect of a 4-week, high dose (Lf-High, 600mg/d) or low dose (Lf-Low, 200mg/d) oral lactoferrin (Lf) intervention versus placebo, on immune cell responses to respiratory virus, circulating immune cell subsets, and systemic inflammation. In healthy older adults (n=103, ≥50 years old), ex vivo cytokine release of interferon (IFN)-α2, IFN-γ, interleukin (IL)-6, and tumour necrosis factor (TNF)-α from isolated peripheral blood mononuclear cells (PBMCs) stimulated with rhinovirus A-16 (RV-16) or influenza A virus (H1N1), circulating immune cell subsets, and plasma IL-6, C-reactive protein (CRP) and TNF-α were assessed at baseline and 4 weeks. Ninety-seven participants completed the intervention (Lf-High n=32, Lf-Low n=31, placebo n=34, withdrawals n=6). There was no difference in RV-16 or H1N1-induced IFN-γ release between groups. At 4-weeks, RV-16-induced IL-6 was lower in Lf-High compared to placebo (P=0.001), and RV-16-induced IFN-α2 was higher in Lf-High compared to Lf-Low (P=0.04). Lf-High increased total T cells (P=0.03) and CD4+ T cells (P=0.03) compared to placebo. Lf-Low reduced neutrophil (P=0.04), natural killer cell (P=0.045), activated CD8+ T cell (P=0.03), and γδ T cell (P=0.03) frequency compared to placebo. Plasma IL-6 (P=0.004) and CRP (P=0.03) were lower following Lf-High compared to Lf-Low, but not placebo. Both high and low dose lactoferrin altered ex vivo immune cell responses after 4 weeks. High dose lactoferrin increased T-cell subsets, promoting adaptive immunity, and reduced systemic inflammation, while low dose lactoferrin reduced proinflammatory and cytotoxic immune cells. High and low dose lactoferrin supplements may have immunoceutical benefits in older adults.
Lactotransferrin (LTF), a critical multifunctional glycoprotein, plays an essential role in the immune defence, growth and development, and milk quality of dairy cows. The regulatory mechanisms governing gene expression are intricate, with sequence variations in the promoter region potentially exerting a substantial impact on gene expression. In this study, sequencing analysis of the bovine lactotransferrin promoter region was conducted, leading to the identification of two linked single nucleotide polymorphism (SNP) sites. A significant association between these SNPs and lactotransferrin content was observed in a cohort of 301 Holstein cows. Subsequently, further investigation into the transcriptional activity of various lactotransferrin genotypes was performed by constructing promoter fragments encompassing different lactotransferrin genotypes. The findings reveal that the two SNPs significantly influence the activity of the lactotransferrin promoter, thereby affecting lactotransferrin expression. These results hold substantial implications for advancing our understanding of the regulatory mechanisms underlying lactotransferrin expression and for the genetic enhancement of dairy cows.
This paper presents an actively controllable nonreciprocal metasurface based on a ferrite–patch structure with PIN diodes for dynamic control. Two activation methods are investigated: (a) phase control, which enables a 30° transmission-phase shift while maintaining nonreciprocal behavior, and (b) ON–OFF control, which switches the response by altering the propagation path. The phase-control metasurface is analyzed using transmission-line theory, full-wave simulation, and experiments, showing good agreement across methods. The ON–OFF design is optimized to suppress bidirectional transmission when ON. Experimental results confirm strong nonreciprocity, though slight frequency shifts arise from FR4 variability, and a back-fitted simulation improves consistency. The proposed dual-control framework provides a compact and low-cost approach to reconfigurable nonreciprocal surfaces that retain the use of permanent magnets for ferrite bias and are applicable to microwave wireless systems, including adaptive isolation, interference control, and tunable shielding. The results demonstrate the feasibility of compact, reconfigurable nonreciprocal metasurfaces using simple biasing circuits and offer design insights for frequency-stable implementations.
The current study was designed to examine the association between a composite Healthy Lifestyle Score (HLS) and thyroid function biomarkers among American adults. This cross-sectional study utilized data from 5,693 adults aged ≥18 years in the NHANES 2007–2012 cycles. A HLS (range 0–6) was constructed based on six modifiable factors: non-smoking, no heavy alcohol intake, normal BMI (18.5–24.9 kg/m²), high physical activity (upper tertile of MET-min/week), adequate sleep (7–9 h/night), and appropriate energy intake. Serum concentrations of thyroid-stimulating hormone (TSH), free and total thyroxine (FT4, TT4), free and total triiodothyronine (FT3, TT3), thyroglobulin (Tg), and thyroid antibodies (TPOAb, TgAb) were measured. Multivariable linear regression adjusted for sociodemographic factors was used to assess associations. In fully adjusted models, each one-point increase in HLS was associated with lower serum FT4 (β = −0.07 ng/dL; 95% CI: −0.10, −0.03; p < 0.001) and TT4 (β = −0.11 µg/dL; 95% CI: −0.15, −0.06; p < 0.001). Compared with participants with an HLS of 0–1, those with HLS 4–6 had lower FT4 (β = −0.20; 95% CI: −0.30, −0.09; p < 0.001) and TT4 (β = −0.36; 95% CI: −0.49, −0.22; p < 0.001). Associations for other thyroid markers were not statistically significant after correction for multiple comparisons (p > 0.05). A healthier lifestyle is inversely associated with serum FT4 and TT4 levels, highlighting potential links between modifiable behaviors and thyroid physiology.
Assisted dying debates overlook the powerful unconscious forces that shape end-of-life decision-making. These dynamics influence personal, clinical and societal judgements and may be contributing to the rapid international expansion of assisted dying practices. Strengthening safeguards requires acknowledging these forces and integrating structured psychological assessment, clinician support and reflective practice to reduce unconscious bias and enhance the reliability, transparency and ethical integrity of decisions.
On 28 August 2023, Canada amended and substantially narrowed its unilateral declaration accepting the compulsory jurisdiction of the International Court of Justice (ICJ). The combined effects of its various reservations — notably, Canada’s new requirement that states must have provided at least six-month advance written notice before instituting ICJ proceedings against it, coupled with its ongoing rights to amend or terminate its declaration with immediate effect — have now rendered Canadian acceptance of Optional Clause jurisdiction compulsory in name only. Canada now appears to control whether any future ICJ cases can ever be brought against it in this way.
The mixing mechanism within a single vortex has been a theoretical focus for decades, while it remains unclear especially under the variable-density (VD) scenario. This study investigates canonical single-vortex VD mixing in shock–bubble interactions (SBI) through high-resolution numerical simulations. Special attention is paid to examining the stretching dynamics and its impact on VD mixing within a single vortex, and this problem is investigated by quantitatively characterising the scalar dissipation rate (SDR), namely the mixing rate, and its time integral, referred to as mixedness. To study VD mixing, we first examine single-vortex passive-scalar (PS) mixing with the absence of a density difference. Mixing originates from diffusion and is further enhanced by the stretching dynamics. Under the axisymmetry and zero diffusion assumptions, the single-vortex stretching rate illustrates an algebraic growth of the length of scalar strips over time. By incorporating the diffusion process through the solution of the advection–diffusion equation along these stretched scalar strips, a PS mixing model for SDR is proposed based on the single-vortex algebraic stretching characteristic. Within this framework, density-gradient effects from two perspectives of the stretching dynamics and diffusion process are discovered to challenge the extension of the PS mixing model to VD mixing. First, the secondary baroclinic effect increases the VD stretching rate by the additional secondary baroclinic principal strain, while the algebraic stretching characteristic is still retained. Second, the density source effect, originating from the intrinsic nature of the density difference in the multi-component transport equation, suppresses the diffusion process. By accounting for both the secondary baroclinic effect on stretching and the density source effect on diffusion, a VD mixing model for SBI is further modified. This model establishes a quantitative relationship between the stretching dynamics and the evolution of the mixing rate and mixedness for single-vortex VD mixing over a broad range of Mach numbers. Furthermore, the essential role of the stretching dynamics on the mixing rate is demonstrated by the derived dependence of the time-averaged mixing rate $\overline {\langle \chi \rangle }$ on the Péclet number ${\textit{Pe}}$, which scales as $\overline {\langle \chi \rangle } \sim {\textit{Pe}}^{{2}/{3}}$.
The unanticipated spillover effects of economic policies on residents’ political trust have seldom been discussed in the literature. This paper examines the impact of the rapid increase in housing prices, triggered by the economic stimulus policies implemented by the Chinese government in response to the 2008 financial crisis, on residents’ political trust. Empirical research based on data from the China Family Panel Studies (CFPS) indicates that the rapid rise in housing prices had differentiated effects on political trust among different age groups: it weakened the political trust of the younger and middle-aged groups but enhanced the political trust felt by elderly groups. Mechanism analysis reveals that the sudden and rapid rise in housing prices exacerbated younger people’s housing difficulties, suppressed their wealth accumulation and undermined their sense of self-efficacy, thus eroding their political trust. The findings of this paper not only extend the research on the formation mechanism of political trust but also broaden the research perspective of housing politics and provide new empirical evidence for understanding the complex dynamic relationship between economic development and political stability.
No existing dietary metric simultaneously captures key dimensions of sustainable healthy diets: dietary variety; intake of animal products; and extent of food processing. This methods and construct development study aimed to identify indicators of a sustainable healthy diet that can be used to inform a multidimensional diet quality score. A modified Delphi was used to gain expert consensus regarding development of a sustainable healthy diet score. Three iterative surveys were conducted between November 2022 and May 2023. Surveys asked participants’ opinion regarding measurement of the three dimensions of sustainable healthy diets (Dimension 1: variety of unprocessed and minimally processed foods; Dimension 2: intake of animal products and; Dimension 3: intake of ultra-processed foods (UPF)) and weighting and aggregation of a score that assesses these three dimensions. Thirteen international experts completed all three surveys. Consensus from experts led to the identification of food-based indicators of sustainable healthy diets. Experts agreed that Dimension 1 should be comprised of 12 food groups, with food groups and scoring ranges informed by the Global Diet Quality Score; Dimension 2 comprised of five food groups with scoring ranges informed by the EAT-Lancet planetary health diet; and Dimension 3 as one food group measured as a cut-off value of ≤10% energy from UPF. There was consensus that each dimension should be equally weighted. Outcomes from this work have been used to inform the development and validation of a multidimensional diet quality score to assess the healthfulness and environmental sustainability of diets among healthy adult populations.
In the fully developed region of a plane turbulent wall jet, the key jet parameters, including the jet velocity Um, jet half-width z1/2 and wall shear stress $ \tau_{0}$, follow the classical power-law scaling with the streamwise distance x: Um$v$/M0 ∼ (xM0/$v$2)−α, z1/2M0/$v$2 ∼ (xM0/$v$2)β and $ \tau_{0}$$v$2/(ρ$M_{0}^{2}$) ∼ (xM0/$v$2)−χ, where M0 is the source kinematic momentum flux, $v$ is the coefficient of kinematic viscosity of fluid, ρ is the mass density of fluid and α, β and χ are the positive scaling exponents. We present a theoretical framework to determine these exponents. Our framework reveals that each jet parameter exhibits a scaling transition. This transition is driven by a shift in the scaling law of the skin-friction coefficient as the Reynolds number Rem = Umzm/$v$ changes over from Rem < 8000 to Rem > 10 000, where zm is the wall-normal location corresponding to the jet velocity. Specifically, α transitions from 4(1 + γ)/(9 − γ) to 13(1 + γ)/[2(14 − γ)], β from 8/(9 − γ) to 13/(14 − γ) and χ from (9 + 7γ)/(9 − γ) to (14 + 12γ)/(14 − γ), where γ ≈ 0.05 is a parameter determined from experiments. We validate the theoretical predictions against extensive experimental datasets from the literature.
The dynamics of a fluid flow about its limit cycle can be analysed through phase reduction analysis – an approach that distils a high-dimensional dynamical system to its scalar phase dynamics. This technique provides insights into phase sensitivity, revealing the mechanisms that advance or delay phase dynamics. The phase-based reduced-order model derived from this approach serves as a foundation for identifying lock-on conditions and designing flow control techniques. Recent work by Sumanasiri et al. (J. Fluid Mech. vol. 1020, 2025, R4) applied phase reduction analysis to the fluid–structure interaction problem of aerofoil flutter in a free stream. Their analysis systematically changed the stiffness of the structural dynamics to decipher the phase dynamics mechanism of flutter. Moreover, they considered the use of optimised heaving motion to suppress the emergence of flutter. Their approach opens new avenues for modifying flow physics through innovative modifications of material properties and structural dynamics.
The bestselling book, If Christ Came to Chicago, was published in 1894. It was a work of sensationalist, exposé journalism, documenting with titillating details the city’s rampant vice, dire social problems such as unemployment and homelessness, and corrupt officials and politicians. The book was, among other things, a contribution to the Social Gospel movement. It even inspired Charles M. Sheldon’s bestselling novel, In His Steps (1896), with its refrain, “What would Jesus do?” The author of If Christ Came to Chicago, W. T. Stead (1849–1912), however, was an Englishman. Stead’s earlier efforts at the New Journalism had been focused upon London, including his “Maiden Tribute of Modern Babylon” articles and ghostwriting In Darkest England and the Way Out (1890) for the founder of the Salvation Army, William Booth. When he turned to the Windy City, however, Stead was attacked for being an interloper, a foreigner who should not have presumed to pronounce a harsh judgment upon an American city. One of his responses to this charge was to try to recast himself as an insider through evoking the category of “our common English-speaking race.” This article explores transatlantic crossings, collaborations, and condemnations. Stead himself died in one of the greatest failed transatlantic crossings of the twentieth century, the sinking of the Titanic.
This study aimed to evaluate patients with beta thalassaemia major using the cardiac electrophysiological index of balance, a new electrocardiography parameter, and to predict ventricular arrhythmias.
Methods:
In this study, 60 beta thalassaemia major and 60 healthy children were included. All patients were evaluated with echocardiography. P-wave dispersion, repolarisation times, repolarisation dispersion times, and cardiac electrophysiological balance index were measured using 12-lead electrocardiography. Heart rate variability parameters were evaluated with a 24-hour Holter electrocardiography.
Results:
Left ventricular functions were similar between the groups. Although repolarisation times (QT, JT, and JTp) were significantly lower in the beta thalassaemia major group, heart rate-corrected repolarisation times were similar. Except for Tpe/QT, which is one of the repolarisation dispersion parameters, the other parameters were similar. The heart rate-corrected cardiac electrophysiological index of balance ratio was significantly higher in the beta thalassaemia major group. QRS duration and QRS-dispersion duration (QRS-d) were similar between the groups. There was a correlation between blood ferritin levels and LVmass-i, Tpe/QT, Tpe/QTc, QTc/QRS ratio, and QT, JT, and JTp values.
Discussion:
Patients with beta thalassaemia major are at high risk for ventricular arrhythmia due to a high QTc/QRS ratio, despite normal left ventricular systolic, diastolic, and autonomic function in the early period. We believe that there is a moderate correlation between blood ferritin levels and the QTc/QRS ratio and that the QTc/QRS ratio can provide important information for the follow-up and evaluation of patients with beta thalassaemia major.
Conclusions:
Despite normal early ventricular function in the beta thalassaemia major group, they were at high risk of ventricular arrhythmias.
