This article offers an advanced and novel investigation into the intricate propagation dynamics of the Belousov–Zhabotinsky system with non-local delayed interaction, which exhibits dynamical transition structure from bistable to monostable. We first solved the enduring open problem concerning the existence, uniqueness and the speed sign of the bistable travelling waves. In the monostable case, we developed and derived new results for the minimal wave speed selection, which, as an application, further improved the existing investigations on pushed and pulled wavefronts. Our results can provide new estimate to the minimal speed as well as to the determinacy of the transition parameters. Moreover, these results can be directly applied to standard localised models and delayed reaction diffusion models by choosing appropriate kernel functions.
Social determinants of health (SDoH), such as socioeconomics and neighborhoods, strongly influence health outcomes. However, the current state of standardized SDoH data in electronic health records (EHRs) is lacking, a significant barrier to research and care quality.
Methods:
We conducted a PubMed search using “SDOH” and “EHR” Medical Subject Headings terms, analyzing included articles across five domains: 1) SDoH screening and assessment approaches, 2) SDoH data collection and documentation, 3) Use of natural language processing (NLP) for extracting SDoH, 4) SDoH data and health outcomes, and 5) SDoH-driven interventions.
Results:
Of 685 articles identified, 324 underwent full review. Key findings include implementation of tailored screening instruments, census and claims data linkage for contextual SDoH profiles, NLP systems extracting SDoH from notes, associations between SDoH and healthcare utilization and chronic disease control, and integrated care management programs. However, variability across data sources, tools, and outcomes underscores the need for standardization.
Discussion:
Despite progress in identifying patient social needs, further development of standards, predictive models, and coordinated interventions is critical for SDoH-EHR integration. Additional database searches could strengthen this scoping review. Ultimately, widespread capture, analysis, and translation of multidimensional SDoH data into clinical care is essential for promoting health equity.
Understanding inequalities in outcomes between demographic groups is a necessary step in addressing them in clinical care. Inequalities in treatment uptake between demographic groups may explain disparities in outcomes in people with first-episode psychosis (FEP).
Aims
To investigate disparities between broad demographic groups in symptomatic improvement in patients with FEP and their relationship to treatment uptake.
Method
We used data from 6813 patients from the 2021–2022 National Clinical Audit of Psychosis data-set. Data were grouped by category type to obtain mean outcomes before adjustment to see whether disparities in outcomes remained after differences in treatment uptake had been accounted for. After matching, the average effect of each demographic variable in terms of outcome change was calculated. Moderator effects on specific treatments were investigated using interaction terms in a regression model.
Results
Observational results showed that patients aged 18–24 years were less likely to improve in outcome, unless adjusted for intervention uptake. Patients classified as Black and Black British were less likely to improve in outcome (moderation effect 0.04, 95% CI 0–0.07) after adjusting for treatment take-up and demographic factors. Regression analysis showed the general positive effect of supported employment interventions in improving outcomes (coefficient −0.13, 95% CI −0.07 to −0.18, P < 0.001), and moderator analysis suggested targeting particular groups for interventions.
Conclusions
Inequalities in treatment uptake and psychotic symptom outcome of FEP by social and demographic factors require monitoring over time. Our analysis provides a framework for monitoring health inequalities across national clinical audits in the UK.
We use multiphase direct numerical simulations to identify, analyse and quantify components of wall-normal heat flux distributions in evaporative vertical falling films with surface modifications at industrially relevant conditions. Previous experiments showed a potential increase of the heat transfer rate through the film by up to 100 % using various types of modifications. We show that the modifications induce significant advective heat transport and hypothesise that four synergistic mixing mechanisms are behind the heat transfer rate improvement. Additionally, we examine how the important surface topology parameters, pitch $\hat {p}$ (distance between modifications), height $\hat {h}$ and the liquid Prandtl number $\mathit {Pr}_l$, influence the mode of heat transport and the Nusselt number $\mathit {Nu}$. We show that $\hat {p}/\hat {h} \approx 10$ maximises $\mathit {Nu}$ and that the optimal pitch is related to the recirculation zone length $L_r$ behind the modification. We find that $L_r/\hat {h} \approx 3.5$ and that $\mathit {Nu} \propto \mathit {Pr}_l^{0.42}$ in the investigated parameter ranges. We also show that all our cases on both smooth and modified surfaces have $\mathit {Pe}_l \gg 1$ and collapse well on a line $\mathit {Nu} \propto (\mathit {Pe}_l/\mathit {Re})^{0.35}$. This relation suggests that $\mathit {Nu}$ is governed by the balance of film mixing, thermal resistance and diffusivity, and that the ratio $\mathit {Pe}_l/\mathit {Re}$ can be used to estimate $\mathit {Nu}$. Our methodology and findings extend the knowledge concerning the mechanisms behind the heat transfer improvement due to surface modifications and facilitate guidelines for designing more efficient modified surfaces in industrial evaporators.
Effectively addressing climate change requires new approaches to action, implementation and social change. Urban societies are profoundly shaped by faith, with religion influencing the physical environment, institutional structures and lives of citizens. Consequently, there is a need to consider seriously religion's role in mobilizing or constraining climate action in cities. Research is presented that shows the potential of faith-based organizations and faith perspectives to minimize and adapt to climate impacts. A framework for sensitively engaging faith communities in urban climate policy is developed, based on the power of shared values among diverse stakeholder groups to mobilize climate action through partnerships.
Technical summary
Global environmental research and policy frameworks have begun to emphasize the importance of culture and multi-sector partnerships for urban sustainability governance. However, there has been little explicit attention paid to religion and belief as ubiquitous urban socio-cultural phenomena. This article reviews literature on the intersection of religion and climate change in the context of cities. Religious responses to climate change are presented as a typology spanning physicalities, practices, ‘prophetic’ imagination and policy arenas. Key themes are then intersected with areas of focal activity presented in the most recent IPCC reports. Religion is shown to offer both opportunities and barriers for effective urban climate adaptation and mitigation. A new model of religious-civic partnership is then developed as a framework for guiding urban climate policy implementation. This model presents religion as vital to shaping the ‘value landscape’ of cities and calls for collaborative action based on identifying, enriching and mobilizing shared values. As cities become increasingly more populous, heterogeneous, globally teleconnected and exposed to climate impacts, there is an urgent need for research and policy that effectively engages with the historic and evolving presence and impact of religion within urban environments.
Social media summary
Effective action on climate change in cities requires new modes of engagement with religious perspectives, grounded in shared values.
Understanding how childhood psychosocial adjustment (CPA) influences later life health outcomes is crucial for developing interventions to mitigate the long-term risk of cardiometabolic diseases (CMDs).
Aims
To investigate the association between CPA and incident CMDs in mid-life, and the mediating roles of educational attainment, smoking habits and depression during young adulthood.
Method
A prospective cohort study utilised data from the 1958 National Child Development Study (NCDS; 1958–2013) and the 1970 British Cohort Study (BCS70; 1970–2018), encompassing 22 012 participants assessed for CPA in childhood, who were subsequently evaluated for educational attainment, smoking habits and depression in young adulthood, followed by assessments for CMDs in mid-life. CPA was assessed using the Bristol Social Adjustment Guides in the NCDS and the Rutter Child Behaviour Scale in the BCS70, with higher scores indicating poorer psychosocial adjustment. The primary outcomes were the mid-life incidences of hypertension, diabetes and obesity.
Results
Compared with children in the lowest tertile for CPA scores, those in the middle tertile had an adjusted odds ratio for hypertension of 0.98 (95% CI 0.90–1.06), whereas those in the highest tertile had an odds ratio of 1.17 (95% CI 1.08–1.26). For diabetes, the corresponding odds ratios (95% CI) were 1.15 (0.98–1.35) and 1.39 (1.19–1.62). For obesity, the corresponding odds ratios (95% CI) were 1.08 (1.00–1.16) and 1.18 (1.09–1.27). These associations were partially mediated by educational attainment (2.4–13.9%) and depression during young adulthood (2.5–14.9%).
Conclusions
Poorer CPA is correlated with the development of hypertension, diabetes and obesity in mid-life. Interventions aimed at improving CPA may help in reducing the burden of these diseases in later life.
Free transverse oscillations of an elastically mounted circular cylinder with low mass-damping are studied with a focus on the effects of the cylinder end condition on structural oscillations and vortex shedding. While the top end of the cylinder pierces the free surface of a water channel, the lower end is changed to have three end conditions: an attached endplate, an endplate unattached from the cylinder at varying gaps and no endplate. All three response branches are examined, with the reduced velocity sweeping $2 \le {U^\ast } \le 15$ (corresponding to a Reynolds number range of $2000 \le Re \le 14\;700$). Although the cylinder oscillations are unaffected by the end condition in the initial and upper branches, they show significant dependency on the end condition in the lower branch. When the endplate is attached or unattached with a small gap, the upper-to-lower branch transition occurs with a sudden decrease in oscillation amplitude, after which the lower branch maintains a near-constant amplitude. For larger gaps or no endplate, with increasing reduced velocity, the oscillation amplitude decreases gradually from its peak without any discernible sign of transition between the upper and lower branches. The three-dimensional effects of the gap are the basis for these differences in oscillation. Atop the strong tip vortex, a low-magnitude streamwise velocity region develops downstream of the cylinder, which delays upper-to-lower branch transition over the cylinder span that sees this low-velocity region. With increasing gap, this low-velocity region and the delay in transition spread over larger spanwise extents, forcing the overall body to oscillate at larger amplitudes.
Reducing rehospitalization has been a primary focus of hospitals and payors. Recurrence of Clostridioides difficile infection (CDI) is common and often results in rehospitalization. Factors that influence rehospitalization for CDI are not well understood.
Objective:
To determine the risk factors that influence rehospitalization caused by CDI.
Design:
A retrospective cohort study from January 1, 2018, to December 31, 2018, of patients aged ≥18 who tested positive for C. difficile while hospitalized.
Setting:
Academic hospital.
Methods:
The risk of rehospitalization was assessed across exposures during and after the index hospitalization using a Cox proportional hazards model. The primary outcome of this study was 60-day CDI-related rehospitalization.
Results:
There were 559 hospitalized patients with a positive CD test during the study period, and 408 patients were included for analysis. All-cause rehospitalization was 46.1% within 60 days of the index hospital discharge. Within 60 days of discharge, 68 patients developed CDI, of which 72.5% (49 of 68) were rehospitalized specifically for the management of CDI. The risk of rehospitalization in patients with CDI was higher among patients who were exposed to systemic antibiotics ([adjusted hazard ratio] aHR: 2.78; 95% CI, 1.36–5.64) and lower among patients who had post-discharge follow-up addressing C. difficile (aHR: 0.53; 95% CI, 0.28–0.98).
Conclusions:
Exposure to systemic antibiotics increased the risk of rehospitalization due to CDI, while post-discharge follow-up decreased the risk of rehospitalization due to CDI. Comprehensive transitions of care for hospitalized patients with C. difficile may reduce the risk of CDI-related rehospitalization.
This article studies some major shifts in the relationship between law and Sufism in South Asian Islam between the eighteenth and the twentieth centuries. It does so by focusing on Shah Wali Allah of Delhi (d. 1762) to examine, first, how these two key facets of Islam interact with each other in his thought and, second, how some influential Muslim intellectuals of the late nineteenth and twentieth centuries have understood and positioned themselves in relation to this aspect of his thought. Though one would be hard pressed to know this from the sanitized modern image of Wali Allah as a scholar of the Quran and hadith, and of a Sufi piety uncompromisingly anchored in them, his Sufism reveals a wide and, from many a modern Muslim perspective, unwieldly range of ideas and practices. Yet it was precisely in that unwieldy breadth and depth that it was generative of some of his key insights into matters of the law. Even as many people have continued to insist on the imbrication of law and Sufism, a sanitization of Wali Allah’s Sufi image serves to highlight wider processes whereby an earlier era’s generative relationship between the two has come to be increasingly attenuated since the late nineteenth century.
Ruth Glacier is situated in the Central Alaska Range, with the Don Sheldon Amphitheater comprising much of its broad accumulation area, directly adjacent to North America's tallest mountain, Denali. From there it funnels through the ‘Great Gorge,’ flanked by steep valley walls reaching over 1500 m. We combine airborne and ground-based radar measurements of ice thickness with satellite-derived surface velocities to constrain ice flux above and below the gorge, and employ a mass conservation approach to estimate the glacier's thickness within the gorge. We measure ice thickness in the amphitheater to reach 950 m, and estimate centerline thickness in the gorge to range from 610 to 960 m. Our estimates are up to two times greater than those suggested by global models, and allow us to confirm that the Great Gorge rivals Hells Canyon as the deepest gorge in North America. We found that the geometry of the gorge prevents radar measurements of ice thickness there since returns from the subglacial valley walls would precede and potentially occlude nadir bed returns. The same may be true of other unmapped mountain glaciers; however, thickness may be determined using appropriately located flux gates where radar sounding is feasible, combined with mass conservation methods.
This article develops an account of territorial justice to understand what is owed to people at risk of climate displacement. I argue that the aim of territorial justice is to secure a globally recognized status, the status of being an equal common possessor of the earth. As a common possessor, every inhabitant of the globe has a claim to a “place” in the world where they can access minimally just material conditions and political institutions, securely pursue their located practices, and exercise self-determination together with others. I apply this theory to generate prescriptions for a just policy response to the risk of climate displacement. Where possible, I argue that a just response should focus on mandatory global taxation to support in situ adaptation. In cases where relocation becomes inevitable, I outline the implications for how just relocation regime should be structured.
Promising studies show that psilocybin-assisted therapy relieves existential distress in patients with serious illnesses, a difficult condition to treat with current treatment options. There is growing interest in this therapy in palliative care. Canada recently amended its laws to allow physicians to request psilocybin for end-of-life distress. However, barriers to access remain. Since implementing psilocybin-assisted therapy within palliative care depends on the attitudes of healthcare providers willing to recommend it, they should be actively engaged in the broader discussion about this treatment option. We aimed (1) to identify issues and concerns regarding the acceptability of this therapy among palliative care professionals and to discuss ways of remedying them and (2) to identify factors that may facilitate access.
Methods
A qualitative study design and World Café methodology were adopted to collect data. The event was held on April 24, 2023, with 16 palliative care professionals. The data was analyzed following an inductive approach.
Results
Although participants were interested in psilocybin-assisted therapy, several concerns and needs were identified. Educational and certified training needs, medical legalization of psilocybin, more research, refinement of therapy protocols, reflections on the type of professionals dispensing the therapy, the treatment venue, and eligibility criteria for treatment were discussed.
Significance of results
Palliative care professionals consider psilocybin-assisted therapy a treatment of interest, but it generates several concerns. According to our results, the acceptability of the therapy and the expansion of its access seem interrelated. The development of guidelines will be essential to encourage wider therapy deployment.
This article focuses on the discussions around female athletes and their emotions in the German and Austrian press of the 1920s. In the course of the sports boom of the interwar years, more and more women participated in public sports competitions and demanded their right to be taken seriously as sportswomen. Their public appearance aroused mixed feelings and heated social debates about how much and what kind of sport was appropriate for women, which were reflected in discussions and narratives around the figure of the “sportsgirl.” Sportsgirls were imbued with a novel emotional style to which ambition and audacity – ways of feeling that were cultivated during competitive sports and that contrasted with traditional bourgeois female feeling rules – were key. Sportsgirls and their emotional style were the subject of many stories, reports, pictures, and articles that were published in the growing sports press of the time – and they were judged and evaluated for the emotional style they embodied. The press was a potent platform and site of the formation of feeling rules; as such, discussions around sportsgirls point to the (embodied) experiences of the athletes and indicate how the emotional style that derived from them was turned into a tool to reshape social conventions and feeling rules for women beyond the sports arena.
Irregular migrants’ flows have, for several years now, been making the news headlines and are at the core of political debates. In a context of polycrisis—characterized by the post COVID-19 pandemic, climate change and its devastating impacts; the disruption of labor markets caused by the fourth industrial revolution and artificial intelligence; or geopolitical tensions in different parts of the globe that threaten the livelihoods of many communities—the desire to move from the developing and emerging world to the West can increase.
The transition from childhood to adolescence presents elevated risks for the onset of psychopathology in youth. Given the multilayered nature of development, the present study leverages the longitudinal, population-based Adolescent Brain Cognitive Development Study to derive ecologically informed risk/resilience profiles based on multilevel influences (e.g., neighborhood and family socioeconomic resources, parenting, school characteristics) and their transition pathways and examine their associations with psychopathology. Latent profile analysis characterized risk/resilience profiles at each time point (i.e., baseline, Year-1, Year-2); latent transition analysis estimated the most likely transition pathway for each individual. Analysis of covariance was used to examine associations between profile membership at baseline (i.e., ages 9–11) and psychopathology, both concurrently and at Year-2 follow-up. Further, we examined the associations between profile transition pathways and Year-2 psychopathology. Four distinct profiles emerged across time – High-SES High-Protective, High-SES Low-Protective, Low-SES High-Family-Risk, and Low-SES High-Protective. Despite reasonably high stability, significant transition over time among profiles was detected. Profile membership at baseline significantly correlated with concurrent psychopathology and predicted psychopathology 2 years later. Additionally, profile transition pathways significantly predicted Year-2 psychopathology, exemplifying equifinality and multifinality. Characterizing and tracing shifts in ecologically informed risk/resilience influences, our findings have the potential to inform more precise intervention efforts in youth.
This paper discusses competing visions of the decolonization of Ghana’s economy during the first decade of the country’s independence from Britain (1957–1966), and the agency and horizon of choice available to the Ghanaian decision-makers in charge of implementing these visions. It focuses on Ghana’s construction industry, both as an important part of the national economy and as a condition for Ghana’s broader social and economic development in the context of colonial-era path-dependencies and Cold War competition. By taking the vantage point of mid-level administrators and professionals, the paper shows how they negotiated British and Soviet technological offers of construction materials, machinery, and design. In response to Soviet claims about the adaptability of their construction resources to Ghana’s local conditions, the practice of adaptation became for Ghanaian architects and administrators an opportunity to reflect on the needs, means, and objectives of Ghana’s construction industry, and on broader visions of Ghana’s economic and social development. Beyond the specific focus on the construction industry, this paper conceptualizes the centrality of adaptation in enforcing technological hegemony during the period of decolonization, and discusses African agency beyond the registers of extraction and resistance that have dominated scholarship on the global Cold War.
