The evolving demographic landscape in the United States is a cause to shift leadership training approaches to better serve diverse populations. This article addresses the call for leadership educators to create inclusive, courageous training environments that reflect the increasing diversity in educational and professional settings. Traditionally, leadership education has centered on White and masculine paradigms, often neglecting the unique experiences of historically marginalized groups. This article emphasizes the importance of recognizing and incorporating social identities into leadership training by using these four key strategies: (1) building trust, (2) acknowledging social identity, (3) identity‐based storytelling, and (4) experiential learning activities. By integrating these strategies, leadership educators can foster environments that are conducive to deeper learning and engagement.

Insular and coastal territories like those in the Seaflower Biosphere Reserve are exposed to strong winds, waves, storms, and hurricanes. In November 2020, Hurricanes Eta and Iota provided a costly reminder of the risks facing Seaflower’s people and ecosystems. Coral reefs and mangroves are natural shields, reducing wind and wave strength during normal and extreme conditions. These coastal protection ecosystem services (ES) are vital for human safety and well-being, and become more important given the heightened vulnerability of low-lying insular islands to climate change impacts. These ecosystems also provide biodiversity refuge ES for fishes and shellfish, key for food security and resilience to global challenges like hurricanes, sea level rise, and global warming. Despite their importance, these valuable ecosystems are threatened by anthropogenic pressures, jeopardizing the survival and well-being of islanders; their restoration and recovery require improved management and decision-making, and heightened societal awareness of our dependence on marine ecosystems and their potential as climate change adaptation solutions. We identify ES provided by coral reefs and mangroves, interdisciplinary management tools, and recommendations to motivate society and decision-makers to expand efforts for the protection, restoration, and use of these ecosystems as Nature-based Solutions for climate change adaptation and mitigation in Seaflower.

Embryos of zooplankton from inland waters and estuaries can remain viable for years in an extreme state of metabolic suppression. How these embryos resist microbial attack with limited metabolic capacity for immune defence or repair is unknown. As a first step in evaluating resistance to microbial attack in dormant zooplankton, surface colonization of the Antarctic freshwater copepod, Boeckella poppei, was evaluated. Scanning electron micrographs demonstrate the outer two layers of a five‐layered cyst wall in B. poppei fragment and create a complex environment for microbial colonization. By contrast, the third layer remains undamaged during years of embryo storage in native sediment. The absence of damage to the third layer indicates that it is resistant to degradation by microbial enzymes. Scanning electron microscopy and microbiome analysis using the 16S ribosomal subunit gene and internal transcribed spacer (ITS) region demonstrate the presence of a diverse microbial community on the embryo surface. Coverage of the embryos with microbial life varies from a sparse population with individual microbes to complete coverage by a thick biofilm. Extracellular polymeric substance binds debris and provides a structural element for the microbial community. Frequent observation of bacterial fission indicates that the biofilm is viable in stored sediments.

People with HIV/AIDS have historically faced barriers to treatment, including stigma, yet advocates have been able to affect change by socially reconstructing stigmatizing public attitudes. People with mental illness face similar challenges, as most are not able to receive services. Mental health legislation could address these gaps, but most bills fail, perhaps due to the persistence of stigma. Thus, this article will (1) discuss forms of mental illness stigma affecting policy processes, (2) examine HIV/AIDS destigmatization strategies, and (3) utilize policy process theory to provide blueprints for advocates to use during development of their advocacy agendas and stigma reduction campaigns.

The Neurohospitalist Core Competencies comprise a set of competency-based learning objectives that encapsulate the knowledge, skills, and attitudes of neurohospitalitists who specialize in the care of hospitalized patients with neurologic conditions. These competencies serve to characterize the rapidly expanding field of neurohospitalist medicine. The 27 chapters are divided into 3 sections entitled: neurological conditions, clinical interventions and interpretation of ancillary studies, and neurohospitalist role in the healthcare system. Each individual learning objective in the chapters describes a specific concept with an action verb to illustrate the behavior that the neurohospitalist exhibits. The individual neurohospitalist may not exhibit mastery in each of the topics included as individual practices vary in scope and practice pattern. A few examples of how the complete set of competencies may be used include in the creation of curricula for neurohospitalist fellowships, to assist in defining the scope of practice of neurohospitalists for administrative leaders of hospitals and departments, and in influencing the direction of further research and quality improvement in the field.

Spatiotemporal satellite image fusion aims to generate remote sensing images satisfying both high spatial and temporal resolution by integrating different satellite imagery datasets with distinct spatial and temporal resolutions. Such fusion technique is crucial for numerous applications that require frequent monitoring at fine spatial and temporal scales spanning agriculture, environment, natural resources and disaster management. However, existing fusion models have difficulty accommodating abrupt spatial changes in land cover among images and dealing with temporally distant image data. This study proposes a novel multi-stream spatiotemporal fusion generative adversarial network (STGAN) model for spatiotemporal satellite image fusion that can produce accurate fused images and accommodate substantial temporal differences between the input images. The STGAN employs a conditional generative adversarial network (GAN) architecture with a multi-stream input design to better learn temporal features. The generator of STGAN comprises convolutional blocks, a spatial transformer module, a channel attention network, and a U-net module designed to better capture spatial and temporal features from the multi-resolution input images. Comprehensive evaluations of the proposed STGAN model have been performed on the Coleambally Irrigation Area and Lower Gwydir Catchment datasets, using both visual inspection and spatial and spectral metrics, including RMSE, ERGAS, SAM, SSIM, and LBP. The experiments show that the proposed STGAN model consistently outperforms existing benchmark models and is capable of generating high-quality fused remote sensing data product of high spatial and temporal resolution.

Phytoplankton have a high potential for CO2 capture and conversion. Besidesbeing a vital food source at the base of oceanic and freshwater food webs, microalgae provide acritical platform for producing chemicals and consumer products. Enhanced nutrient levels,elevated CO2, and rising temperatures increase the frequency of algal blooms, which often havenegative effects such as fish mortalities, loss of flora and fauna, and the production of algaltoxins. Harmful algal blooms (HABs) produce toxins that pose major challenges to waterquality, ecosystem function, human health, tourism, and the food web. These toxins havecomplex chemical structures and possess a wide range of biological properties with potentialapplications as new therapeutics. This review presents a balanced and comprehensiveassessment of the roles of algal blooms in generating fixed carbon for the food chain,sequestering carbon, and their unique secondary metabolites. The structural complexity ofthese metabolites has had an unprecedented impact on structure elucidation technologies andtotal synthesis, which are highlighted throughout this review. In addition, the influence ofbiogeochemical environmental perturbations on algal blooms and their influence on biospheric environments is discussed. Lastly, wesummarize work on management strategies and technologies for the control and treatment of HABs

Background Over their evolutionary history, corals have adapted to sea level rise and increasing ocean temperatures, however, it is unclear how quickly they may respond to rapid change. Genome structure and genetic diversity contained within may highlight their adaptive potential. Results We present chromosome-scale genome assemblies and linkage maps of the critically endangered Atlantic acroporids, Acropora palmata and A. cervicornis. Both assemblies and linkage maps were resolved into 14 chromosomes with their gene content and colinearity. Repeats and chromosome arrangements were largely preserved between the species. The family Acroporidae and the genus Acropora exhibited many phylogenetically significant gene family expansions. Macrosynteny decreased with phylogenetic distance. Nevertheless, scleractinians shared six of the 21 cnidarian ancestral linkage groups as well as numerous fission and fusion events compared to other distantly related cnidarians. Genetic linkage maps were constructed from one A. palmata family and 16 A. cervicornis families using a genotyping array. The consensus maps span 1,013.42 cM and 927.36 cM for A. palmata and A. cervicornis, respectively. Both species exhibited high genome-wide recombination rates (3.04 to 3.53 cM/Mb) and pronounced sex-based differences, known as heterochiasmy, with 2 to 2.5X higher recombination rates estimated in the female maps. Conclusions Together, the chromosome-scale assemblies and genetic maps we present here are the first detailed look at the genomic landscapes of the critically endangered Atlantic acroporids. These data sets revealed that adaptive capacity of Atlantic acroporids is not limited by their recombination rates. The sister species maintain macrosynteny with few genes with high sequence divergence that may act as reproductive barriers between them. In the Atlantic Acropora, hybridization between the two sister species yields an F1 hybrid with limited fertility despite the high levels of macrosynteny and gene colinearity of their genomes. Together, these resources now enable genome-wide association studies and discovery of quantitative trait loci, two tools that can aid in the conservation of these species.

Studies show that a nexus exists between racialized campus experiences, racial-ethnic identity, and engagement in campus activities for Black college men and shapes their perceptions about an institution's commitment to support the communities they represent. Yet, there is limited knowledge about how this nexus may unfold ecologically for this student population during their undergraduate experience. Using the Phenomenological Variant Ecological System Theory, this qualitative study describes how 31 Black college males leveraged their identities to manage self and societal appraisals, cope with stress experienced in university programs, and navigate feelings of marginalization and sense of belonging during their undergraduate experience.

Here we describe the data obtained by a successful proof-of-concept initiative to launch the first ocean color imager on board a CubeSat satellite and collect research-grade imagery at severalfold higher spatial resolution than any other ocean color satellite mission. The 3U CubeSat, named SeaHawk, flew at a nominal altitude of 585 km. Its ocean color sensor, HawkEye, collected 7,471 research-grade push-broom images of 230 × 780 km² at best-in-class 130 × 130 m² per pixel. The sensor is built with comparatively low-cost commercial off-the-shelf optoelectronics and was designed to match NASA SeaWiFS ocean color specifications, including wavelengths, bandwidths, and signal-to-noise ratios. HawkEye’s design for ocean color remote sensing combined with its high spatial resolution make the imagery especially well-suited for coastal, estuarine, and limnological applications. Ultimately, the successful mission provided open access to a rich global dataset of calibrated and quality-controlled imagery for use in aquatic ecology and environmental change studies.

Aim The aim of this study was to develop an outcome measure for caregivers of children with food allergy. Methods A community‐informed measure development process was utilised to generate a novel parent‐reported outcome tool for caregivers of children with food allergy. We conducted focus groups with parents and caregivers of food‐allergic ( n = 18) children, following which a team of coders identified themes and generated an initial set of candidate items. These items were reviewed by content‐area experts ( n = 10) using content validity indices. We then conducted a series of cognitive interviews with parents of children with food allergy ( n = 12) validating the instrument draft. Results We describe the results of these development steps as well as future steps to produce the final, validated form of the measure. The resultant 91‐item measure is intended for parents of children ages two to 12 years. Conclusion This measure fills a unique need in the field by leveraging key stakeholders' perspectives to develop and subsequently validate a novel parent‐reported measure of parent and family food allergy impacts of children ages two to 12 years old.

The exceptional diversity of shallow‐water marine fishes contributes to the nutrition of millions of people worldwide through coastal wild‐capture fisheries, with different species having diverse nutritional profiles. Fishes in ecosystems are reservoirs of micronutrients with benefits to human health. Yet, the amount of micronutrients contained in fish species on coral reefs and in shallow tropical waters is challenging to estimate, and the micronutrients caught by fisheries remain uncertain. To assess whether micronutrient deficiencies could be addressed through specific fisheries management actions, we first require a quantification of the potentially available micronutrients contained in biodiverse reef fish assemblages. Here, we therefore undertake a broad heuristic assessment of available micronutrients on tropical reefs using ensemble species distribution modelling and identify potential mismatches with micronutrients derived from summarising coastal fisheries landings data. We find a mismatch between modelled estimates of micronutrients available in the ecosystem on the one hand and the micronutrients in small‐scale fisheries landings data. Fisheries had lower micronutrients than expected from fishes in the modelled assemblage. Further, fisheries were selective for vitamin A, thus resulting in a trade‐off with other micronutrients. Our results remained unchanged after accounting for the under‐sampling of fish communities and under‐reporting of small‐scale fisheries catches—two major sources of uncertainty. This reported mismatch indicates that current estimates of fished micronutrients are not adequate to fully assess micronutrient inventories. However, small‐scale fisheries in some countries were already selective towards micronutrient mass, indicating policies that target improved access, distribution and consumption of fish could leverage this existing high micronutrient mass. Enhanced taxonomic resolution of catches and biodiversity inventories using localised species consumption surveys could improve understanding of nature‐people linkages. Improving fisheries reporting and monitoring of reef fish assemblages will advance the understanding of micronutrient mismatches, which overall indicate a weak uptake of nutritional goals in fisheries practices. The decoupling between micronutrients in ecosystems and in fisheries catches indicates that social, economic, and biodiversity management goals are not shaped around nutritional targets—but this is key to achieve a sustainable and healthy planet for both people and nature.

Metrics of coral physiology can be used to identify changes in coral health due to environmental stressors or management actions. One of the most unprecedented stressors to Caribbean corals is the spread of stony coral tissue loss disease (SCTLD), which also resulted in the novel management action of in-water amoxicillin treatments on active disease lesions. Though highly effective at halting lesions and preventing coral mortality, possible unintended consequences of topical application of amoxicillin to coral tissue were unknown. We used in-water instrumentation to measure and compare photosynthesis (P), respiration (R), P/R ratios, and calcification of corals that were visually healthy, actively diseased, and diseased but treated with amoxicillin paste. Measurements occurred across three time points and two species – Orbicella faveolata and Montastraea cavernosa. Across all metrics, treatment type did not cause significant differences, indicating that neither SCTLD lesions nor amoxicillin treatments impacted the physiology of adjacent tissues. There were significant variations among time points, which may have resulted from changes to coral health across the reef, variations due to environmental variables, or other unknown factors. We suggest that physiological metrics could be an interesting way to fate track coral health across short- and long-term timeframes. We also conclude that amoxicillin treatments as a tool to halt SCTLD are not detrimental to respiration, photosynthesis, or calcification rates of adult corals.

The oldest pottery of the American Southeast, Stallings fiber-tempered ware (ca. 2550–1850 BCE), is typically associated with shell midden deposits, ostensibly supporting narratives that link pottery innovation with aquatic exploitation and increased sedentism. However, technofunctional and sourcing data on Stallings pottery belie a direct connection between shellfishing, sedentism, and ceramic cooking technology. Refining understanding of the relationships among these variables requires better data on the actual uses of early pottery. This chapter presents pilot data on organic residues preserved in the sherds of Stallings vessels from four sites in the middle Savannah River valley of Georgia and South Carolina. These data support the hypothesis that emergence of early pottery in the Southeast does not comport with the aquatic-centric pattern of early forager pottery documented elsewhere, but instead reflect the complex relationships among mobility, seasonality, and ritual intensification in a dynamic landscape of group interactions.

Mollusca, the second-most diverse animal phylum, is estimated to have over 100,000 living species with great genetic and phenotypic diversity, a rich fossil record, and a considerable evolutionary significance. Early work on molluscan system-atics was grounded in morphological and anatomical studies. With the transition from oligo gene Sanger sequencing to cutting-edge genomic sequencing technologies, molecular data has been increasingly utilised, providing abundant information for reconstructing the molluscan phylogenetic tree. However, relationships among and within most major line-ages of Mollusca have long been contentious, often due to limited genetic markers, insufficient taxon sampling and phylogenetic conflict. Fortunately, remarkable progress in molluscan systematics has been made in recent years, which has shed light on how major molluscan groups have evolved. In this review of molluscan systematics, we first synthesise the current understanding of the molluscan Tree of Life at higher taxonomic levels. We then discuss how micromolluscs, which have adult individuals with a body size smaller than 5 mm, offer unique insights into Mollusca's vast diversity and deep phylogeny. Despite recent advancements, our knowledge of molluscan systematics and phylogeny still needs refinement. Further advancements in molluscan systematics will arise from integrating comprehensive data sets, including genome-scale data, exceptional fossils, and digital morphological data (including internal structures). Enhanced access to these data sets, combined with increased collaboration among morphologists, palaeontologists, evolutionary developmental biologists, and molecular phylogeneticists, will significantly advance this field.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues its largely aseasonal spread with millions of cases per year. Highly sensitive, point-of-care testing is critical for rapid detection of coronavirus disease 2019 (COVID-19) cases and initiation of antiviral therapy to avert adverse health outcomes and reduce onward transmission of the virus. While hundreds of COVID-19 diagnostics received emergency use authorization from the FDA during the pandemic, significantly fewer have navigated the course to FDA clearance or approval. Here, we determined the clinical performance of the Cepheid Xpert Xpress CoV-2 plus for detection of SARS-CoV-2 in 3,750 anterior nasal swab (NS) specimens and nasopharyngeal swab (NPS) from 32 sites in comparison to the FDA-authorized BioFire Respiratory Panel 2.1. Three-quarters of specimens collected were tested on the Xpert Xpress CoV-2 plus in the point-of-care setting. Overall positive percent agreement (PPA) was 98.1% (95% CI: 96.7%–98.9%) and negative percent agreement (NPA) was 98.3% (97.7%–98.7%). Performance of the Xpert Xpress CoV-2 plus was slightly improved in NS compared to NPS specimens, with PPA of 99.3% versus 97.0% (Fisher’s exact test, P = 0.06) and NPA of 98.3% versus 98.2% ( P = 0.89), respectively. Assay PPA was similar between untrained and trained users (98.7% vs 97.3%, P = 0.75), while NPA was slightly improved for untrained users (99.0% vs 97.6%, P = 0.0003). This study showed that Cepheid Xpert Xpress COV-2 plus is highly sensitive and specific/has high PPA and NPA for detection of SARS-CoV-2 from both NS and NPS specimens. IMPORTANCE Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to cause millions of infections and tens of thousands of deaths per year in the United States. While the FDA authorized hundreds of SARS-CoV-2 tests during the public health emergency, significantly fewer have made the transition to being cleared or approved. There continues to be a need for FDA-authorized point-of-care SARS-CoV-2 testing that can be performed by untrained users. We conducted a large prospective study of the Cepheid Xpert Xpress CoV-2 plus test for detection of SARS-CoV-2 in both nasal and nasopharyngeal swabs by trained and untrained users. The assay demonstrated excellent clinical performance characteristics and, as a result of this study, was cleared by the FDA.
