We introduce the super Alternative Daugavet property (super ADP), which lies strictly between the Daugavet property (DP) and the ADP. A Banach space X has the super ADP if for every element x in the unit sphere and every relatively weakly open subset W of the unit ball intersecting the unit sphere, there are an element $y\in W$ and a modulus one scalar θ such that $\|x+\theta y\|$ is almost two. Spaces with the DP satisfy this condition, and it implies the ADP. We first provide examples of super ADP spaces that fail the DP. We show that the norm of a super ADP space is rough, hence the space cannot be Asplund, and we also prove that the space fails the point of continuity property (particularly, the Radon–Nikodým property). In particular, we get examples of spaces with the ADP that fail the super ADP. For a better understanding of the differences between the super ADP, the DP and the ADP, we consider the localizations of these properties and prove that they behave rather differently. As a consequence, we provide characterizations of the super ADP for spaces of vector-valued continuous functions and of vector-valued integrable functions.
The crime of rape has been postulated as an unlawful violation of an individual’s rights or interests. However, this article argues that sexual violence against women in Thailand was traditionally viewed as a breach of an interpersonal hierarchy. It was not until the modern criminalization of rape that lawyers attempted to identify the victim’s individual rights as the essence of the crime. By examining the legal techniques employed by these lawyers in drafting, implementing, and adjudicating the crime, the article contends that the voices and demands of female subjects of rape have been silenced or misplaced. The article will offer studies of legal techniques used by lawyers from various institutions in articulating rape and constructing its subjects from the 19th century to the present. This jurisprudence provides context for the current debate on sexual violence in Thailand and makes it possible to critically reassess the right-based conceptualization of rape law.
I show that a neat expression emerges for the number of spheres in each shell of an octahedron composed of close packed spheres, and that from this expression we can compute the value of the packing density for an infinite array of such spheres.
In this research work, a low-profile elliptical microstrip antenna has been designed with a recessed ground structure. A portion of the ground below the substrate has been cut out for the implementation of the recessed ground. Due to the recessed ground, the gain and bandwidth of the conventional antenna are increased along with the shifting of the resonant band toward high-frequency range. First-time theoretical analysis of the recessed ground is performed using a 2-D capacitance model to understand the effect of its dimensions on the dielectric constant of the antenna and the amount of shifting of the primary resonant frequency. A comprehensive parametric study of the dimension of the recessed ground was carried out to optimize the performance of the antenna. The conventional antenna without recessed ground generates a resonant frequency of 2.35 GHz with a resonant band of 2.28–2.4 GHz (S11≤−10dB) and a gain of −1.35 dB. After using optimum rectangular recessed ground, the resonant frequency of the conventional antenna is shifted to 2.58 GHz, occupying the 2.49–2.69 GHz frequency band with 0.5 dB gain. Therefore, the proposed antenna with recessed ground covers the 2.5–2.69 GHz WiMAX application band with enhanced gain and bandwidth.
This article explores the history and development of British manifestations of a Black diasporic anti-colonial anti-fascist political tradition that stretches across the twentieth century. It centers the experiences and reflections of Black activists and intellectuals in Britain, exploring their efforts to theorize about fascism as a manifestation of white supremacy. The article explores what we can learn about British society and political culture by returning to the overlooked and excluded experiences of Black British activists and intellectuals—in particular, their theoretical and physical encounters with what they called British “fascism” from the 1930s to the 1970s. Journeying from interwar anti-colonial Marxist political writing, Black periodicals in the 1950s and 1960s, to the publications of the British Black Power movement, the article ultimately argues that these encounters confront historians of modern Britain with a different and generative way of thinking about British racism and British fascism in relational terms.
This note offers a preliminary survey of archives containing photographic material – both digitized and nondigitized – related to northern Ghana. Despite the region’s historical marginalization, this condition has not necessarily resulted in a scarcity of sources. On the contrary, numerous archives preserve rich and underexplored photographic documentation. By identifying and describing key collections across institutions such as the White Fathers phototèque, the Ministry of Information in Accra, the University of Cambridge, the British Museum, the Bodleian Library, the Imperial War Museum, the National Archives in London, and the Smithsonian National Museum of African Art, this note seeks to illuminate underexplored visual sources.
Using high-fidelity numerical simulations based on a lattice Boltzmann framework, the advection-enhanced transport of a passive scalar from a prolate spheroid in simple shear flow has been thoroughly investigated across various parameters, including the spheroid’s aspect ratio, particle-to-fluid density ratio, Reynolds number (defined as ${\textit{Re}}=\textit{GR}^{2}/\nu$, where $G$ is the flow shear rate, $R$ is the radius of a sphere of the same volume as the spheroid and $\nu$ is the kinematic viscosity of the fluid) and Schmidt number (defined as $\textit{Sc}=\nu /D$, where $D$ is the diffusivity of passive scalar transport). The Reynolds number is constrained to the range of 0 ≤ Re ≤ 1, where the prolate spheroid tumbles around its minor axis, aligned with the vorticity axis, in an equilibrium state. Several key findings have emerged: (i) particle inertia significantly influences the uniformity of the spheroid’s tumbling, affecting flow patterns around the spheroid and, consequently, the modes of scalar transport; (ii) both uniform and non-uniform tumbling generate a scalar line in the fluid with elevated scalar concentration, which sweeps through the wake region and merges with clusters of previously formed scalar lines; (iii) fluid passing over the spheroid carries the passive scalar downstream along these scalar lines; (iv) variations in the uniformity of spheroid tumbling result in distinct flow patterns and scalar transport modes, leading to different transport rates; (v) within the studied parameter ranges, increased particle inertia enhances the scalar transport rate; (vi) when particle inertia is minimal, the dimensionless scalar transport rate for different aspect ratios converges to a common dependence on the Péclet number. These phenomena are analysed in detail.
Regular physical activity for adults is associated with optimal appetite regulation, though little work has been performed in adolescents. To address this gap in the literature, we conducted a study examining appetite across a range of physical activity and adiposity levels in adolescent males. Healthy males (N=46, 14-18 years old) were recruited across four body weight and activity categories: normal weight/high active (n=11), normal weight/low active (n=13), overweight, obese/high active (n=14), overweight, obese/low active (n=8). Participants from each group completed a six-hour appetite assessment session on Day 0, followed immediately by a 14-day free-living physical activity and dietary assessment period on Days 1-14, and a fitness test session occurring between Days 15-18. Subjective and objective assessment of appetite, resting energy expenditure, body composition using dual energy absorptiometry‘, and thermic effect of feeding was conducted on Day 0. Physiological variables in the normal weight low active group that were different than their peers included lower fat-free mass, cardiorespiratory fitness, glucose/fullness response to a standardized meal, thermic effect of feeding in response to a standardized meal, lower self-rated fullness and satiety, and higher self-rated hunger to a standardized meal. Conversely, the overweight, obese high active group displayed better subjective appetite responses, but higher insulin responses to a standardized meal. Taken together, these results suggest that physical inactivity during adolescence has a negative impact on metabolic health and appetite control which may contribute to future weight gain.
Popular narratives suggest that the effects of Christian nationalism should be more heavily concentrated among white Americans. The academic literature on Christian nationalism largely reflects this take, often asserting that it is effectively white Christian nationalism. We question such pronouncements, as they have come without systematic analysis across the broad range of issue areas needed to justify subgroup segmentations. Utilizing national oversamples of Black and Latino Christians (alongside white Christians), we assess the relationship between standard measures of Christian nationalism and attitudes toward policies that vary in their degree of racialization. Our findings qualify typical narratives: consistent with a theory of Christian nationalism as sacralized in-group protection, we find effects that diverge by racial groups on racialized issues but otherwise converge. We close by discussing the implications of these findings and offering suggestions for future work linking race with Christian nationalism.
In recent years, measuring hair cortisol concentration in dairy cows has gained popularity as a welfare indicator. The aim of this study was to evaluate the usefulness of measuring hair cortisol concentration (HCC) in dairy cows as an indicator of dairy cow welfare. A total of 290 cows from six commercial herds located in Spain, Italy and Finland (two herds each) were included in the study. A hair sample was taken from each cow and cut into two parts (study period T1 and T2). HCC was measured using an automated assay based on a competitive solid phase chemiluminescent enzyme immunoassay. Data relevant to each animal and its welfare (animal-based assessment according to the Welfare Quality protocol, veterinary treatments, meteorological data, cows’ parity and stage of lactation) were collected during the study. The welfare data were used to categorize cows into three welfare classes at each study period (T1 and T2), representing animals with good, medium and poor welfare. Analytical validation of the HCC automated assay was performed on a sub-sample of collected hair and included determination of accuracy, precision, sensitivity and stability of the method. A linear mixed model was fitted to explore the associations between log transferred HCC and welfare class, herd, stage of lactation, parity and season. The results of analytical validation showed that the HCC automated assay method was accurate and able to measure HCC in a linear manner with inter- and intra-assay precision with CVs less than 15%. HCC was explained by the variables herd, cow parity and study period (T1 or T2). We found no evidence that lactation stage and welfare class explained HCC at the individual animal level. This study highlights the challenges of using HCC as an indicator of animal welfare on commercial farms.
Interfaces subjected to strong time-periodic horizontal accelerations exhibit striking patterns known as frozen waves. In this study, we experimentally and numerically investigate the formation of such structures in immiscible fluids under high-frequency forcing. In the inertial regime – characterised by large Reynolds and Weber numbers, where viscous and surface tension effects become negligible – we demonstrate that the amplitude of frozen waves scales proportionally with the square of the forcing velocity. These results are consistent with vibro-equilibria theory and extend the theoretical framework proposed by Gréa & Briard (2019 Phys.Rev.Fluids4, 064608) to immiscible fluids with large density contrasts. Furthermore, we examine the influence of both Reynolds and Weber numbers, not only in the onset of secondary Faraday instabilities – which drive the transition of frozen wave patterns toward a homogenised turbulent state – but also in selecting the dominant wavelength in the final saturated regime.
On 27 October 2021, Cambridge University’s Jesus College commemorated the historic return to Nigeria of the bronze statue of a cockerel called “Okukur.” This was looted from the ancient Kingdom of Benin in 1897 by British colonizers. The college resolved to relinquish ownership to the Oba, who is the cultural, religious, and legal head of Benin. On 23 March 2023, Nigeria’s President Muhammadu Buhari decreed that the “ownership of the artefacts… is vested in the Oba.” The genesis of this order was controversies about the ownership, control, and management of returning objects. This article analyzes the role of the traditional institution of governance in the socio-legal politics of cultural heritage restitution in Nigeria. Building on the traditional leadership’s claims on the returned artworks, it explains the need to use the momentum of restitution to evaluate and improve the effectiveness of the national and international legal systems to protect cultural heritage.
Coercive control (CC) represents a significant proportion of intimate partner violence (IPV) cases in the UK and globally. While theoretical models on CC exist, none so far includes a psychological perspective. As cognitive behavioural theory (CBT) has a robust evidence base as an IPV intervention for women survivors, it can also be used in the development of a psychological model for CC, from the perspective of survivors. Such a model may have utility as a psychotherapeutic formulation tool and providing training on psychological aspects and impact of CC to other professionals involved in survivors’ care.
Method:
Fourteen women with self-identified experience of CC were screened and interviewed. Constructivist grounded theory was used to analyse the interviews.
Results:
Six theoretical codes were developed: vulnerability factors (difficult childhood experiences, negative previous romantic relationships, and low self-esteem), cognitions (thoughts about worthlessness, isolation, being deserving of the abuse, confusion, hope, being treated unfairly, and suicidal ideation), affect (shame, fear, sadness, and anger), maintaining factors (perceived consequences of leaving, financial situation, low self-esteem, and social norms), behaviours (unhelpful coping strategies of dissociation, subjugation, avoidance, and substance misuse, and protective factors were spending time with loved ones, physical activity, and committing to career and interests), and impact (poor physical health, depression, anxiety, trauma, financial difficulties, and chronic mistrust).
Conclusions:
The results of this study constitute a preliminary CBT model of women survivors’ experiences of CC. Further research is required to test and further develop the model, especially the vulnerability factors and mental health implications of experiencing CC.
Key learning aims
(1) To provide information that supports the need for healthcare professionals to be aware of and receive training on coercive control.
(2) To provide insight into women survivors’ experiences of coercive control within heterosexual relationships.
(3) To provide guidance on how psychological professionals can work with women survivors of coercive control to formulate their experiences and plan interventions.
This cross-sectional study examined the association between diet price and diet quality in a national sample of Australian adults (n 1956). Diet recall data from the 2020 International Food Policy Study were linked to a national food and beverage price dataset. Daily diet price was calculated by summing the median non-promotional prices of all foods and beverages recorded in diet recall data, priced per gram (or millilitre) and adjusted for edible portions. Diet quality was determined using the Australian Dietary Guideline Index 2013 (scored out of 115). Linear regression models tested the association between the diet price (per dollar and per ten-dollar increments) and diet quality, adjusted for education, age and sex. A positive association was observed, where diet quality increased by 0·09 units (95 % CI 0·05, 0·14) for every $AU 1 increase in diet price. Daily diet price explained approximately 8 % of the variation in diet quality across the sample (R2 = 0·08). When categorised in ten-dollar increments, participants with diet prices < $AU 10/d had a lower mean diet quality score (51·96) compared with all other diet price categories, 5–6 points lower than those whose diet was > $30/d. Diet price appeared to be a modest yet significant determinant of diet quality for Australian adults in 2020. Additional analyses are needed to investigate these associations during recent food inflation. As diet quality appears to be lowest for people who spend the least on food, government action to increase priority communities’ food budgets may help improve the nutritional quality of population diets.
Shift work-induced circadian disruption has been linked to various cardiometabolic diseases, including obesity, diabetes and cardiovascular disease. Limited studies have explored the impact of different variables such as night work durations, intensities, and chronotype on cardiometabolic risk. This study aimed to determine the impact of circadian disruption on cardiometabolic risk markers in shift workers. This case-control study was conducted with 104 male workers (shift workers; n=52, mean age ±SD; 43.3±10.2, and non-shift workers; n=52, mean age ±SD; 41.2±9.8). Shift work details were determined via an interviewer-administered questionnaire. Cardiometabolic risk was evaluated through anthropometric (height, weight, waist circumference, and body composition), biochemical (fasting glucose and lipid profile), clinical (blood pressure), and dietary assessment (24-hour recalls from working and non-working days). The chronotype was determined via the Munich Chronotype Questionnaire (MCTQ). Shift workers had significantly higher mean body fat percentage (31.7, 22.7% p=0.031), systolic blood pressure (138.6, 128.5 mmHg p=0.009), pulse rate (78.7, 72.3 bpm p=0.015), triglycerides (1.60, 1.30mmol/l p=0.021), and LDL-C (3.90, 3.40 mmol/l p=0.012) than non-shift workers. Evening chronotype shift workers had significantly higher visceral fat levels (12.8, 8.90 p=0.001), systolic blood pressure (137.0, 127.6 mmHg p=0.006), pulse rate (82.7, 73.3 bpm p=0.005), and LDL-C (4.00,3.40 mmol/l p=0.039) than shift workers with a morning chronotype. In conclusion, shift workers exhibited higher metabolic risk markers than non-shift workers. Shift workers with evening chronotypes had higher cardiometabolic risk than morning chronotypes. Further research is warranted to elucidate the underlying mechanisms and inform targeted interventions for individuals engaged in shift work, considering chronotypes.
We study the mechanics of evaporation and precipitate formation in pure and bacteria-laden sessile whole blood droplets in the context of disease diagnostics. Using experimental and theoretical analysis, we show that the evaporation process has three stages based on evaporation rate. In the first stage, edge evaporation results in a gelated contact line along the periphery through a sol–gel phase transition. The intermediate stage consists of a gelated front propagating radially inwards due to capillary flow and droplet height regression in pinned mode, forming a wet-gel phase. We unearthed that the gelation of the entire droplet occurs in the second stage, and the wet-gel formed contains trace amounts of water. In the final slowest stage, the wet gel transforms into a dry gel, leading to desiccation-induced stress forming diverse crack patterns in the precipitate. Slow evaporation in the final stage is quantitatively measured using evaporation of trace water and associated transient delamination of the precipitate. Using the axisymmetric lubrication approximation, we compute the transient droplet height profile and the erythrocytes concentration for the first two stages of evaporation. We show that the precipitate thickness profile computed from the theoretical analysis conforms to the optical profilometry measurements. We show that the drop evaporation rate and final dried residue pattern do not change appreciably within the parameter variation of the bacterial concentration typically found in bacterial infection of living organisms. However, at exceedingly high bacterial concentrations, the cracks formed in the coronal region deviate from the typical radial cracks found in lower concentrations.
