Visual representations of dromedaries in Greco‐Roman antiquity and the middle ages: Imagining the other before orientalism
Authors: Sauquet Mathilde 
Published: July 2023

AbstractThe diorama Lion Attacking a Dromedary found in the Carnegie Museum of Natural History rightfully belongs to an Orientalist artistic tradition that crystallized many of the discriminatory misrepresentations of people of color that have plagued our society to this day. Camels and dromedaries, associated with the “Orient,” constituted an integral element of the exotic vision held and disseminated by Europeans. The motif of the camel and its dark‐skinned rider, however, emerged many centuries prior to the context of colonial Europe and across media. This paper explores the surfacing and subsequent proliferation of the camel as a symbol of otherness and foreignness in Antiquity and the Middle Ages in relation to Christian and imperial ideologies. I argue that the material evidence points to a long‐standing associative combination of the camel with people of color and/or of foreign origin and thus establishes a precedent worth our attention as we continue to wrestle with the racial and political ramifications of Lion Attacking a Dromedary.

AbstractChronic wounds can severely limit patient's social life. This cross‐sectional study investigated quantitatively social support of patients with chronic wounds, its association with health‐related quality of life as well as qualitatively changes in social participation of these patients. Overall, 263 patients from seven countries participated. The most frequent wound class was leg ulcer (49.2%). Results revealed generally high levels of social support (mean global score: 5.5) as measured with the Multidimensional Scale of Perceived Social Support. However, individuals differed considerably (range 1.0–7.0). All dimensions of social support differed by patients' family and living situations (p < 0.001 to p = 0.040) and were positively correlated with generic health‐related quality of life (r = 0.136–0.172). Having children, living with others and being in a relationship were significant predictors of having higher global social support. Patients reported great support from family members. Many participants reported no changes in relationships with friends. Wound care managers took an important role and provided additional emotional support. Patients reported a range of discontinued activities. Despite the high overall level of social support, inter‐individual differences should be acknowledged. The importance of family carers should be acknowledged to be able to reduce caregiver burden and to ensure high‐qualitative wound care.

AbstractIn the response of the flood disaster in Germany 2021 a vast number of spontaneous volunteers (SVs) participated. They organized coordinating services, developed emergent forms of SVs and thus hold the potential to improve existing flood managing capacities. This raises the need for in‐depth knowledge about SVs and organization, the use of information and communication technologies (ICT), social and individual aspects. This article analyzed results of an online survey (n = 2636) with the aim to discuss challenges and potentials to develop SVs as social innovations in flood risk management. As a result, SVs are strong value‐based motivated, can be psychologically stressed and travel long distances, especially when they got aware of helping possibilities via social media. Disaster relief organizations rarely cooperate with or integrate SVs, but when they collaborate, SVs' satisfaction with authorities increases significantly. Based on the results, this article derives preplanning of useful concepts consider safety aspects, ICT utilization, foster mutual respect between SVs and authorities and supporting sense of community as key results for development of social innovations. Especially in light of pandemics, social crisis like refugee movements, and climate change‐related disasters, the requirement rises for engaging SVs.

Published: July 2023

AbstractBackground and AimsPrevious literature suggests an association between non‐alcoholic fatty liver disease (NAFLD) and infections. We aimed to determine the rate and risk of severe infections in NAFLD compared to the general population.MethodsIn this population‐based cohort study, we used national registers to identify all patients with a hospital‐based diagnosis of NAFLD in Sweden 1987–2020 (n = 14 869). The patients were matched with ≤10 comparators from the general population for age, sex, municipality, and calendar year (n = 137 145). Cox regression was used to estimate hazard ratios (HR) for infections in patients with NAFLD compared to comparators. Cumulative incidences were calculated while accounting for competing risks (non‐infection death and liver transplantation).ResultsSevere infections leading to death or hospitalization occurred in 1990 (13.4%) patients with NAFLD and 9899 (7.2%) comparators during a median of 4.5 and 6.1 years of follow‐up, respectively. The rate of severe infections per 1000 person‐years was higher in patients with NAFLD (21.0) than comparators (9.1) independently of components related to the metabolic syndrome (adjusted HR 1.9, 95% CI = 1.8–2.0). Infection‐related mortality was also higher in NAFLD compared to comparators (adjusted HR 1.8, 95% CI = 1.6–2.2). The 10‐year cumulative incidence of severe infections was 16.6% (95% CI = 15.8–17.4) in NAFLD and 8.0% (95% CI = 7.8–8.2) in comparators.ConclusionNAFLD was associated with severe infections and infection‐related mortality, independently of components associated with the metabolic syndrome. Increased clinical vigilance of severe infections in NAFLD may diminish the risk of premature death.
Deep order flow imbalance: Extracting alpha at multiple horizons from the limit order book
Authors: Kolm Petter N. , Turiel Jeremy , Westray Nicholas 
Published: July 2023

AbstractWe employ deep learning in forecasting high‐frequency returns at multiple horizons for 115 stocks traded on Nasdaq using order book information at the most granular level. While raw order book states can be used as input to the forecasting models, we achieve state‐of‐the‐art predictive accuracy by training simpler “off‐the‐shelf” artificial neural networks on stationary inputs derived from the order book. Specifically, models trained on order flow significantly outperform most models trained directly on order books. Using cross‐sectional regressions, we link the forecasting performance of a long short‐term memory network to stock characteristics at the market microstructure level, suggesting that “information‐rich” stocks can be predicted more accurately. Finally, we demonstrate that the effective horizon of stock specific forecasts is approximately two average price changes.
A place‐based approach to understanding firms' voluntary environmental engagement: The role of regional pressures in the case of Korea
Authors: Song Jongdae 
Published: July 2023

AbstractEnvironmental management literature has extensively explored why the regulated community, particularly private firms, join voluntary environmental programs (VEPs) in which participants promise to regulate “beyond compliance.” However, the notion of locus has been rarely considered a key determinant of a firm's VEP participation. This study examines how regional pressures encourage firms' VEP participation. Drawing on a dataset of over 1000 industrial facilities related to five government sponsored VEPs in Korea, it investigates how three types of regional pressures—regulators, industrial peers, and community members—affect firms' decision to join VEPs. The major findings are that firms located in the same region as their conglomerate peers, as well as firms located in a place where a large amount of odor pollutant is released, are more likely to participate in VEPs. These results demonstrate the impact of social attributes derived from the geographic location of firms on facilities' VEP engagement.
The revolution can be improvised: An intrinsically motivating approach to equity, diversity, and inclusion
Authors: Caruso Heather Maiirhe 
Published: July 2023

AbstractWith unfolding advances in anti‐discrimination policy, communication technology, and affordable transportation, society is gaining an historic opportunity to embrace differences in background and perspective as part of ordinary life. Unfortunately, we can be overly pessimistic about the prospect of attracting stakeholders to the work, because overwhelming societal barriers have long perpetuated narrow and inauspicious views of our paths forward. The result can be our unnecessary and ineffective reliance on top‐down imperatives as necessary to compel engagement. Improvisation can help us do better. After describing how contextual conditions are shifting favorably, I illustrate the prospective benefits of an improvisational approach to EDI—particularly in fostering intrinsic motivation—and extend basic psychological needs theory to provide guidance for successful implementation.

IntroductionMalaria in pregnancy is a major driver of maternal and infant mortality in sub-Saharan Africa. The WHO recommends the administration of intermittent preventive treatment with sulfadoxine pyrimethamine (IPTp-SP) at antenatal care (ANC) visits. Despite being a highly cost-effective strategy, IPTp-SP coverage and uptake remains low. A pilot project was conducted to assess the cost-effectiveness (CE) of community-based delivery of IPTp (C-IPTp) in addition to ANC delivery to increase IPTp uptake in the Democratic Republic of Congo (DRC), Madagascar (MDG), Mozambique (MOZ) and Nigeria (NGA).MethodsCosts and CE estimates of C-IPTp were calculated according to two scenarios: (1) costs in ‘programmatic mode’ (ie, costs if C-IPTp was to be implemented by national health systems) and (2) costs from the pilot project. The effectiveness of C-IPTp was obtained through estimates of the averted disability-adjusted life-years (DALYs) associated with maternal clinical malaria and anaemia, low birth weight and neonatal mortality.ResultsNet incremental costs of C-IPTp ranged between US$6138–US$47 177 (DRC), US$5552–US$31 552 (MDG), US$10 202–US$53 221 (MOZ) and US$667–US$28 645 (NGA) per 1000 pregnant women, under scenarios (1) and (2), respectively. Incremental cost-effectiveness ratios (ICERs) ranged between US$15–US$119 in DRC, US$9–US$53 in MDG, US$104–US$543 in MOZ and US$2–US$66 in NGA per DALY averted, under scenarios (1) and (2), respectively. ICERs fall below the WHO recommended CE threshold based on the gross domestic product per capita.ConclusionFindings suggest that C-IPTp is a highly cost-effective intervention. Results can inform policy decisions on adopting and optimising effective interventions for preventing malaria in pregnancy.

ObjectiveTo assess health system responsiveness (HSR) and associated factors for delivery care in public health facilities, Northeast Ethiopia.DesignInstitutional-based cross-sectional study.SettingSouth Wollo zone, Ethiopia.ParticipantsA total of 430 women who delivered within the study period from 1 June 2022 to 5 July 2022 were included for this analysis.OutcomeHSR.MethodsInstitutional-based cross-sectional study was conducted from 1 June 2022 to 5 July 2022 in nine public health facilities. The data were collected through semistructured interviewer administered questionnaire, reviewing delivery registration books and client charts. HSR for delivery care was assessed by eight domains based on WHO responsiveness assessment framework. Binary logistic regression analyses were employed to check the association of variables with HSR. An adjusted OR (AOR) with 95% CI was determined to show the strength of association, and a p<0.05 was taken as level of statistical significance.ResultsIn this study, the health system was responsive for 45.8% (95% CI 41.1% to 50.6%) of delivered mothers. The highest (74.2%) and lowest (45.8%) rated domains were dignity and basic amenity, respectively. In multivariable logistic regression analysis, caesarian delivery (AOR 3.67, 95% CI 1.91 to 7.06), obstetric complication in current pregnancy (AOR 0.45, 95% CI 0.23 to 0.85), referred during labour (AOR 0.36, 95% CI 0.18 to 0.69), birth within 17:30–8:30 hours (AOR 0.51, 95% CI 0.32 to 0.81) and good satisfaction (AOR 5.77, 95% CI 3.44 to 9.69) were statistically significant associated factors with HSR.ConclusionThe overall responsiveness of delivery care was low. Basic amenities, choice of provider and social support domains were least rated responsiveness domains. If health professionals give emphasis to mothers during spontaneous vaginal delivery, able to prevent obstetric complications, and if health facilities increase the number of professionals to duty time, handover, the referred mothers appropriately; having clean and attractive delivery wards will be important interventions to improve responsiveness for delivery care.
Exploring physical and biological manifestations of burnout and post-traumatic stress disorder symptoms in healthcare workers: a scoping review protocol
Authors: Kottler Janey , Gingell Monica J , Khosla Shaveta , Kordzikowski Mitchell , Raszewski Rebecca , Chestek David , Maki Katherine 
Published: July 2023

IntroductionThe COVID-19 pandemic has strained the mental and physical well-being of healthcare workers (HCW). Increased work-related stress and limited resources have increased symptoms of anxiety, depression, insomnia and post-traumatic stress disorder (PTSD) in this population. Stress-related disorders have been strongly associated with long-term consequences, including cardiometabolic disorders, endocrine disorders and premature mortality. This scoping review aims to explore available literature on burnout, PTSD, and other mental health-associated symptoms in HCW to synthesise relationships with physiological and biological biomarkers that may be associated with increased risk of disease, creating an opportunity to summarise current biomarker knowledge and identify gaps in this literature.Methods and analysisThis scoping review uses the Arksey and O’Malley six-step scoping review methodology framework. The research team will select appropriate primary sources using a search strategy developed in collaboration with a health sciences librarian. Three reviewers will initially screen the title and abstracts obtained from the literature searches, and two reviewers will conduct independent reviews of full-text studies for inclusion. The research team will be reviewing literature focusing on which burnout and/or PTSD-associated physiological and biological biomarkers have been studied, the methodologies used to study them and the correlations between the biomarkers and HCW experiencing burnout/PTSD. Data extraction forms will be completed by two reviewers for included studies and will guide literature synthesis and analysis to determine common themes.Ethics and disseminationThis review does not require ethical approval. We expect results from this scoping review to identify gaps in the literature and encourage future research regarding improving biological and physiological biomarker research in HCW. Preliminary results and general themes will be communicated back to stakeholders. Results will be disseminated through peer-reviewed publications, policy briefs and conferences as well as presented to stakeholders to an effort to invest in HCW mental and physical health.
Dilaton photoproduction in a magnetic dipole field of pulsars and magnetars

AbstractAccording to Einstein–Maxwell-dilaton theory, the dilaton field $$\varvec{\psi }$$

We discuss three different frameworks for this analysis: (i) an update limited to the experimental data but using the same theoretical framework as in earlier works, (ii) a full update concerning both the experimental inputs and the theoretical framework, (iii) an analysis without the LHCb results on electron modes. The comparison between these various sets of results allows us to identify the differences stemming from the various components of the analysis: new experimental results, new inputs for the hadronic form factors, the role played by LHCb data on electron modes.

Coupling of electron and vibrational spectroscopy with false colour imaging for the investigation of natural dyes in historical fabrics (15th–18th centuries)

Published: July 2023

AbstractA series of historical textile fragments belonging to the Guggenheim collection had been previously studied by FORS and IRR imaging. The need for further analysis emerged in order to get a better understanding of the applied dyes. Under this perspective, SERS measurements and false colour images (UVFC and IRFC) were acquired on selected samples dated back between the fifteenth and the eighteenth centuries and constituted by velvets, embossed velvets, brocades, brocatelles, damasks, lampasses, satins, gros and taffetas of Italian manufacture. The cross-checking of spectroscopic data allowed for confirming some of the results previously obtained, but in the majority of cases much more complex situations were found. On many occasions, SERS and FORS demonstrated their complementarity allowing for discovering the use of mixtures instead of single dye as previously assumed. In addition to indigotin, cochineal and tannins, already identified in the previous investigation, new data allowed for determining the presence of orcein, annatto, luteolin, quercetin and saffron. The FC images supported the obtained results but evidenced the need for the generation of a complete database of historical dyes employed with different dyeing procedures, substrates, mordants and as mixtures with different proportions. The multi-technique approach, involving both non-invasive and micro-invasive methods, also allowed for checking the compatibility of compounds with both the declared historical period and the origin of the investigated textile fragments.
