AbstractFollowing the 2016 EU referendum on Britain's membership in the European Union, many people described themselves as “Leavers” or “Remainers.” Here, we examine the emotional responses associated with Brexit identities using survey data collected from two nationally representative samples of the British public in 2019 (N = 638) and 2021 (N = 2,058). Confirmatory factor analysis indicated that many in both samples had coherent Leave or Remain identities. Remain and, to a lesser extent, Leave identities (regardless of how people actually voted in the referendum) predicted distress about Brexit‐related events and clinical symptoms of depression and anxiety at both time points. Structural equation models suggested that the effect of identities on symptoms was largely mediated by distress about Brexit‐related events. We demonstrate a lasting impact of Brexit on the mental health of UK citizens and show that the formation of novel political identities has been more important in this process than voting behavior.
Structure, essence and existence in chemistry
Authors: Hendry Robin Findlay 
Published: August 2023

AbstractPhilosophers have often debated the truth of microstructural essentialism about chemical substances: whether or not the structure of a chemical substance at the molecular scale is what makes it the substance it is. Oddly they have tended to pursue this debate without identifying what a structure is, and with some confusion and about what a chemical substance is. In this paper I draw on chemistry to rectify those omissions, providing a pluralist account of structure, clarifying what (according to chemistry) a chemical substance is and defending microstructural essentialism, as I understand that position. I then give an account of the existence of composite substances and objects in chemistry, an issue that goes back to Aristotle.

AbstractThe Bahamian Archipelago has been the subject of extensive studies of stratigraphy, carbonate island morphology and diagenetic overprinting for many decades. A recently‐acquired dataset comprised of high‐resolution light detection and ranging, tightly spaced cored boreholes with image logs, thin sections, porosity and permeability measurements, and isotopic geochemical analyses provides a unique opportunity to perform detailed sequence stratigraphic analysis. This multi‐faceted study first establishes a new high‐resolution sequence stratigraphic framework for the Sandy Point area of San Salvador Island, encompassing six unconformity bound sequences (exposure surfaces) representing varying lengths of missing time. The stratigraphically lowest sequence is Late Pliocene in age and is dominated by reef facies capped by an extensive laminar caliche that represents 1.5 million years of exposure. The overlying Early Pleistocene is split into two sequences, EP1 and EP2, which are both dominated by low‐energy subtidal facies. The upper three sequences are tied to the Marine Isotope Stage 11, 9 and 5e interglacials, and are distinctly different in facies composition and architecture, being dominated by higher energy facies distributed in a more complex mosaic. The new stratigraphic framework highlights significant changes in depositional style and facies architecture that can be linked to increasing sea‐level amplitude oscillations and greater climate gradient at the Mid Pleistocene Transition. The well‐constrained framework is then used to provide key context for observed complex diagenetic evolution through repeated sea‐level inundation and subaerial exposure. These results suggest that well‐developed subaerial exposure surfaces drive increases in non‐matrix features in the subsequent stratigraphic package following exposure as the well‐cemented exposure surface acts to concentrate fluid flow and dissolution. Integration of non‐matrix features within this framework highlights the importance of dissolution/cementation patterns on formation of these modified unconformity surfaces for focusing later meteoric diagenesis and creating enhanced fluid flow pathways for continued multicyclic diagenetic events.
Police‐perpetrated racism and health in African American and Black communities
Authors: Hoggard Lori S. , Lutchman Mariah T. 
Published: August 2023

AbstractThis brief review article focuses on police‐perpetrated racism against African American and Black (AAB) communities, typically in the form of police brutality, police violence, and aggressive policing. We assert that police‐perpetrated racism constitutes a racial justice and public health problem. A growing body of literature supports this assertion, with the consequences and correlates of direct police contact, vicarious police contact, and place‐based exposure to aggressive policing including mental health (e.g., anxiety symptoms, depressive symptoms, trauma) and physical health (e.g., poorer self‐rated health, hypertension) sequelae. We assert that eradicating police‐perpetrated racism requires acknowledgement of the historical landscape of policing as well as the ways in which police‐perpetrated racism maintains racial hierarchies. We conclude by making recommendations for promoting racial equity in policing.

Published: August 2023

AbstractThe COVID‐19 pandemic brought new attention to the issues of food insecurity faced by individuals throughout the United States, a stressor exacerbated by disruptions to work status and supply chains. The burden of food insecurity likely carries consequences for whether individuals feel capable of pursuing their broad goals and life engagements; put differently, food insecurity may pose a threat to people perceiving a sense of purpose in life. The current study tested this claim across three samples taken during 2020 (n = 2009), 2021 (n = 1666), and 2022 (n = 1975). Participants completed inventories for perceived food insecurity, sense of purpose, depressive symptoms, and anxiety, among other measures. Results found consistent negative associations between food insecurity and sense of purpose across all three samples. In addition, food insecurity moderated associations between sense of purpose and depressive or anxiety symptoms. Sense of purpose was more strongly negatively associated with depressive and anxiety symptoms for those participants who reported no food insecurity. That said, sense of purpose remained negatively associated with psychological distress even among those reporting food insecurity.

AbstractBackgroundMedical trainees are expected to perform complex tasks while experiencing interruptions, which increases susceptibility to errors of omission. In our study, we examine whether documentation of clinical encounters increases reflective thinking and reduces errors of omission among novice learners in a simulated setting.MethodsIn 2021, 56 senior medical students participated in a simulated paging curriculum involving urgent inpatient cross‐cover scenarios (sepsis and atrial fibrillation). Students responded to pages from standardized registered nurses (SRNs) via telephone, gathered history, and discussed clinical decision‐making. Following the phone encounter, students documented a brief note (documentation encounter). A ‘phone’ score (number of checklist items completed in the phone encounter) and a ‘combined’ score (number of checklist items completed in the phone and documentation encounters) were calculated. Data were analyzed for differences between the phone scores (control) and combined scores using T‐tests and McNemar test of symmetry.FindingsFifty‐four students (96%) participated. Combined scores were higher than phone scores for sepsis (72.8 ± 11.3% vs. 67.9 ± 11.9%, p < 0.001) and atrial fibrillation (74.0 ± 10.1% vs. 67.6 ± 10.0%, p < 0.001) cases. Important items, such as ordering blood cultures for sepsis (p = 0.023) and placing the patient on telemetry for atrial fibrillation (p = 0.013), were more likely to be present when a note was documented.DiscussionThis study suggests that documentation provides a mechanism for learners to reflect, which could increase important diagnostic and therapeutic interventions.ConclusionDocumentation by novice medical learners may improve patient care by allowing for reflection and reducing errors of omission.
Development of hidden curriculum skills in a COVID‐19 vaccination centre
Authors: Driessen Johannes , Hearn Russell 
Published: August 2023

AbstractBackgroundDuring the COVID‐19 pandemic, many medical students were deployed as vaccinators. This study set out to capture the lived experience of students at a London‐based mass vaccination site, understand what they learned, how this learning compared to their experience of usual medical education and how any identified benefits might be leveraged in a post‐pandemic context.MethodsStudent vaccinators (n = 8) were recruited from the vaccine clinic workforce and invited to complete semi‐structured interviews about their experiences. Thematic analysis was conducted on interview transcripts to identify significant concepts, which were interpreted in the context of available literature.FindingsParticipants' experiences aligned broadly with the undergraduate curriculum. However, many also identified hidden curriculum areas developed through their work as vaccinators, including professionalism, self‐regulating learning and ethical decision‐making.DiscussionThe need for adequate support, whilst promoting autonomy, was highlighted as vital in supporting professional identity formation within a community of practice, benchmarking clinical knowledge and performance, and in support of student wellbeing, in the face of challenging real‐world clinical encounters.ConclusionIncreased entrustment of clinical activity could be implemented in primary and secondary care settings to reproduce the benefits experienced by student vaccinators in front‐line roles during the COVID‐19 pandemic. Further work might consider how to maximise these benefits and increase inclusion and participation.
A single center experience for clinical evaluation of paroxysmal cold hemoglobinuria and Donath‐Landsteiner testing

AbstractBackgroundParoxysmal cold hemoglobinuria (PCH) is a rare form of autoimmune hemolytic anemia (AIHA), mainly affecting children. The diagnosis and management are challenging due to similarities to other causes for AIHA and limited availability to Donath‐Landsteiner (DL) testing.Study Design and MethodsIn this single‐center retrospective study, we aimed to characterize the clinical presentation and outcomes of PCH patients, defined as having positive Donath‐Landsteiner antibodies, compared to a cohort of AIHA patients.ResultsDL‐positive patients were observed to have higher lactate dehydrogenase levels and lower reticulocyte counts compared to DL‐negative patients, although this was not statistically significant. We also observed that using steroids in DL‐positive patients did not significantly impact their recovery.DiscussionOur findings support the limited published data on PCH patients and further prompt larger multicenter studies to further characterize these patients so that they are more readily identified, especially in centers where DL antibody testing is not readily available.
Notes on the ecology and distribution of a water flea complex (Anomopoda, Daphniidae) revealed by new DNA barcodes in the Iberian Peninsula

Published: August 2023

AbstractAvailable DNA barcodes of freshwater zooplankton are scarce in regions like the Iberian Peninsula, which harbours many rare and endemic species and is considered a hotspot of crustacean biodiversity. Recently, a new species of Ceriodaphnia (Cladocera: Daphniidae) was described using morphological analysis of specimens in the Mediterranean region and molecular data on a single locality in southern Spain. In our study, we detected the presence of the newly discovered taxa and here, we provide new DNA sequences on the barcoding region mitochondrial cytochrome c oxidase I together with ecological information of the recently described Ceriodaphnia smirnovi. Additionally, we built a molecular phylogenetic tree and genetically compared these specimens with previously available mitochondrial DNA sequences and with new sequences of the genus recovered in Iberia. Our data suggest that this morphospecies might contain some cryptic taxa and might be more common than previously thought, occupying temporary to semi‐permanent ecosystems, with vegetation and highly variable pH and turbidity conditions. Moreover, the existence of a non‐identified clade within our phylogenetic tree requires additional morphological research. Our study highlights the need for further research on microcrustacean biota to better constrain its spatial boundaries, phylogenetic relationship and determine species hiding cryptic diversity.

The role of spatial curvature in constraining the Universe anisotropies across a Big Bounce
Authors: Giovannetti Eleonora , Montani Giovanni 
Published: August 2023

AbstractWe study the implementation of Polymer Quantum Mechanics (PQM) to a system decomposed into a quasi-classical background and a small quantum subsystem, according to the original Vilenkin proposal. We develop the whole formalism in the momentum representation that is the only viable in the continuum limit of the polymer paradigm and we generalize the fundamental equations of the original Vilenkin analysis in the considered context. Then, we provide a Minisuperspace application of the theory, first considering a Bianchi I cosmology and then extending the analysis to a Bianchi IX model in the limit of small anisotropies. In both these cases, the quasi-classical background is identified with an isotropic bouncing Universe whereas the small quantum subsystem contains the anisotropic degrees of freedom. When the Big Bounce scenario is considered, we obtain that in the Bianchi I model the anisotropies standard deviation is regular at $$t=0$$

but still increases indefinitely, whereas in the presence of the harmonic Bianchi IX potential such same quantity is bounded and oscillate around a constant value. As a consequence, we demonstrate that the picture of a semiclassical isotropic Bounce can be extended to more general cosmological settings if the spatial curvature becomes relevant when the anisotropic degrees of freedom are still small quantum variables.
Probabilistic Safe WCET Estimation for Weakly Hard Real-time Systems at Design Stages
Authors: Lee Jaekwon , Shin Seung Yeob , Briand Lionel C. , Nejati Shiva 
Published: August 2023

Weakly hard real-time systems can, to some degree, tolerate deadline misses, but their schedulability still needs to be analyzed to ensure their quality of service. Such analysis usually occurs at early design stages to provide implementation guidelines to engineers so they can make better design decisions. Estimating worst-case execution times (WCET) is a key input to schedulability analysis. However, early on during system design, estimating WCET values is challenging, and engineers usually determine them as plausible ranges based on their domain knowledge. Our approach aims at finding restricted, safe WCET sub-ranges given a set of ranges initially estimated by experts in the context of weakly hard real-time systems. To this end, we leverage (1) multi-objective search aiming at maximizing the violation of weakly hard constraints to find worst-case scheduling scenarios and (2) polynomial logistic regression to infer safe WCET ranges with a probabilistic interpretation. We evaluated our approach by applying it to an industrial system in the satellite domain and several realistic synthetic systems. The results indicate that our approach significantly outperforms a baseline relying on random search without learning and estimates safe WCET ranges with a high degree of confidence in practical time (< 23 h).
Container-based Virtualization for Real-time Industrial Systems—A Systematic Review
Authors: Queiroz Rui , Cruz Tiago , Mendes Jérôme , Sousa Pedro , Simões Paulo 
Published: August 2023

Industrial Automation and Control systems have matured into a stable infrastructure model that has been kept fundamentally unchanged, using discrete embedded systems (such as Programmable Logic Controllers) to implement the first line of sensorization, actuation, and process control and stations and servers providing monitoring, supervision, logging/database and data-sharing capabilities, among others. More recently, with the emergence of the Industry 4.0 paradigm and the need for more flexibility, there has been a steady trend towards virtualizing some of the automation station/server components, first by using virtual machines and, more recently, by using container technology. This trend is pushing for better support for real-time requirements on enabling virtualization technologies such as virtual machines and containers.
This article provides a systematic review on the use of container virtualization in real-time environments such as cyber-physical systems, assessing how existing and emerging technologies can fulfill the associated requirements. Starting by reviewing fundamental concepts related to container technology and real-time requirements, it goes on to present the methodology and results of a systematic study of 37 selected papers covering aspects related to the enforcement of real-time constrains within container hosts and the expected task latency on such environments, as well as an overview of container platforms and orchestration mechanisms for RT systems.
Description of a new species of the genus Anthaxia (Haplanthaxia Reitter, 1911) from India with molecular barcoding and phylogenetic analysis

Published: August 2023

This paper deals with the description of a new Anthaxia (subgenus Haplanthaxia Reitter, 1911) species from southern India, which belongs to the Anthaxia (H.) winkleri Obenberger, 1914 species-group: Anthaxia (H.) keralensis sp. nov. In addition to a morphological description, we also generated mt. COI DNA sequences and discuss the results of a phylogenetic analysis of the new species with previously deposited COI DNA sequences of Anthaxia spp. In a maximum-likelihood phylogenetic analysis, the new species shared the same hypothetical ancestor node with A. melancholica Gory, 1841 and similar molecular characteristics (~48% similarity) with A. tenella Kiesenwetter, 1858 and A. corinthia Reiche & Saulcy, 1856. More systematic studies are required to understand the species diversity, distribution, biology, and evolutionary significance of the Anthaxia (H.) species groups.

Any new economic activity in a virgin area brings landscape changes, making it essential to document baseline biodiversity areas to understand the impacts on habitats. Avifaunal inventories are critical for previously undocumented areas, especially in a wintering site for shorebirds in the Central Asian Flyway, to formulate site- and species-specific conservation management tools. We present an annotated checklist of avifauna from the Valinokkam Lagoon in the Ramanathapuram district of Tamil Nadu. We recorded the first baseline avifaunal data for 154 species belonging to 16 orders and 46 families from August 2016 to February 2023. Order-wise, Charadriiformes dominated the study site with 47 species; followed by Passeriformes with 39 species and Pelecaniformes with 20 species. Winter visitors constituted 37.6 % (58 species) and one Passage Migrant Rosy Starling Pastor roseus. The relative abundance indicated that 94 species were C (common), 41 species were UC (uncommon), and 19 species were Ra (rare). Eleven Near Threatened (NT) species: Oriental Darter Anhinga melanogaster, Painted Stork Mycteria leucocephala, Black-headed Ibis Threskiornis melanocephalus, Spot-billed Pelican Pelecanus philippensis, Black-tailed Godwit Limosa limosa, Bar-tailed Godwit Limosa lapponica, Great Stone-curlew Esacus recurvirostris, Eurasian Curlew Numenius arquata, Curlew Sandpiper Calidris ferruginea, Red-necked Stint Calidris ruficollis and Red Knot Calidris canutus, one Endangered (EN) species Great Knot Calidris tenuirostris, and one unassessed Hanuman Plover Charadrius seebohmi according to the IUCN Red List category. This baseline data highlights the importance of Valinokkam Lagoon as an important wintering site in the Central Asian Flyway on the southeast coast of India for migratory shorebirds and the need for more conservation priorities for regional endemic birds like Hanuman Plover.
