Predicting pack-ice seal occupancy of ice floes along the Western Antarctic Peninsula.

We explore the habitat use of Antarctic pack-ice seals by analyzing their occupancy patterns on pack-ice floes, employing a novel combination of segmented generalized linear regression and fine-scale (∼ 50 cm pixel resolution) sea ice feature extraction in satellite imagery. Our analysis of environmental factors identified ice floe size, fine-scale sea ice concentration and nearby marine topography as significantly correlated with seal haul out abundance. Further analysis between seal abundance and ice floe size identified pronounced shifts in the relationship between the number of seals hauled out and floe size, with a positive relationship up to approximately 50 m2 that diminishes for larger floe sizes and largely plateaus after 500 m2.

Penguin colony georegistration using camera pose estimation and phototourism.

Satellite-based remote sensing and uncrewed aerial imagery play increasingly important roles in the mapping of wildlife populations and wildlife habitat, but the availability of imagery has been limited in remote areas. At the same time, ecotourism is a rapidly growing industry and can yield a vast catalog of photographs that could be harnessed for monitoring purposes, but the inherently ad-hoc and unstructured nature of these images make them difficult to use. To help address this, a subfield of computer vision known as phototourism has been developed to leverage a diverse collection of unstructured photographs to reconstruct a georeferenced three-dimensional scene capturing the environment at that location.

Industry price guarantees for publicly funded medicines: learning from Project NextGen for pandemics and beyond.

The affordability of publicly funded medicines has been a longstanding concern. In 2023, the Biden administration took several steps on this front, including incorporation of a price constraint in an agreement between the US Biomedical Advanced Research and Development Authority (BARDA) and Regeneron Pharmaceuticals, Inc. to develop a new COVID-19 monoclonal antibody.

The influence of biotic and abiotic factors on the bacterial microbiome of gentoo penguins (Pygoscelis papua) in their natural environment.

The microbiome is a key factor in the health, well-being, and success of vertebrates, contributing to the adaptive capacity of the host. However, the impact of geographic and biotic factors that may affect the microbiome of wild birds in polar environments is not well defined. To address this, we determined the bacterial 16S rRNA gene sequence profiles in faecal samples from pygoscelid penguin populations in the Scotia Arc, focusing on gentoo penguins.

Play as Occupation: The State of Our Science and a Research Agenda for the Profession.

Occupational therapists view play through a unique lens. Considering play as a human occupation, and one to which all people have a right, places occupational therapists among a special group of professionals championing play. This State of the Science article seeks to increase awareness regarding the occupational therapy profession's contributions and to situate those contributions within the larger body of literature on play while also promoting further study of play as an occupation.

Sources of variability in Luminex bead-based cytokine assays: Evidence from twelve years of multi-site proficiency testing.

Bead array assays, such as those sold by Luminex, BD Biosciences, Sartorius, Abcam and other companies, are a well-established platform for multiplexed quantification of cytokines and other biomarkers in both clinical and discovery research environments. In 2011, the National Institute of Allergy and Infectious Diseases (NIAID)-funded External Quality Assurance Program Oversight Laboratory (EQAPOL) established a proficiency assessment program to monitor participating laboratories performing multiplex cytokine measurements using Luminex bead array technology. During every assessment cycle, each site was sent an assay kit, a protocol, and blinded samples of human sera spiked with recombinant cytokines.

Using the Theory of Affordances to Understand Environment-Play Transactions: Environmental Taxonomy of Outdoor Play Space Features-A Scoping Review.

Objective: To investigate the relationship between environmental characteristics of outdoor play spaces and children's outdoor play and to develop an environmental taxonomy to support the analysis of play affordances in community play spaces.

"Can I Play Too?" A Qualitative Study of Outdoor Play and Participation Among Autistic Preschoolers.

Importance: Outdoor play in homes, schools, and communities provides children with unique opportunities to explore their worlds, develop fundamental life skills, and experience belonging. However, few studies have explored outdoor free play among autistic preschoolers in natural settings from a neurodivergent-informed perspective.

Objective: To explore the play preferences, opportunities, and challenges in outdoor play for autistic preschoolers.

Triangulation of epidemiological evidence and risk of bias evaluation: A proposed framework and applied example using formaldehyde exposure and risk of myeloid leukemias.

Evidence triangulation may help identify the impact of study design elements on study findings and to tease out biased results when evaluating potential causal relationships; however, methods for triangulating epidemiologic evidence are evolving and have not been standardized. Building upon key principles of epidemiologic evidence triangulation and risk of bias assessment, and responding to the National Academies of Sciences, Engineering, and Medicine (NASEM) call for applied triangulation examples, the objective of this manuscript is to propose a triangulation framework and to apply it as an illustrative example to epidemiologic studies examining the possible relationship between occupational formaldehyde exposure and risk of myeloid leukemias (ML) including acute (AML) and chronic (CML) types. A nine-component triangulation framework for epidemiological evidence was developed incorporating study quality and ROB guidance from various federal health agencies (i.

The mindful leader: a review of leadership qualities derived from mindfulness meditation.

Mindfulness has been practiced by global leaders and companies as an efficient way to build effective leadership. Because of its popularity, plus the lack of a comprehensive theoretical framework that explains it in a leadership context, the research literature has called for a coherent account of the qualities that is derived by those leaders that practice mindfulness. Here, we aim to answer that call, by clarifying .

Quantifying potential marine debris sources and potential threats to penguins on the West Antarctic Peninsula.

Marine pollution is becoming ubiquitous in the environment. Observations of pollution on beaches, in the coastal ocean, and in organisms in the Antarctic are becoming distressingly common. Increasing human activity, growing tourism, and an expanding krill fishing industry along the West Antarctic Peninsula all represent potential sources of plastic pollution and other debris (collectively referred to as debris) to the region.

The Importance of Primary Care Physicians in the Diagnosis and Exclusion of Rare Syndromes: A Case Study of Ruling Out PHACE Syndrome.

PHACE (posterior fossa malformations, hemangioma, arterial anomalies, coarctation of the aorta/cardiac defects, and eye abnormalities) syndrome is an extremely uncommon condition that requires a team of physicians to properly diagnose, treat, and follow. Patients are at risk of posterior fossa malformations, hemangiomas, and arterial, cardiac, eye, and sternal cleft abnormalities. These syndrome hallmarks can cause severe functional and developmental issues or, in the worst case, death.

Antarctic Penguin Biogeography Project: Database of abundance and distribution for the Adélie, chinstrap, gentoo, emperor, macaroni and king penguin south of 60 S.

Background: The Antarctic Penguin Biogeography Project is an effort to collate all known information about the distribution and abundance of Antarctic penguins through time and to make such data available to the scientific and management community. The core data product involves a series of structured tables with information on known breeding sites and surveys conducted at those sites from the earliest days of Antarctic exploration through to the present. This database, which is continuously updated as new information becomes available, provides a unified and comprehensive repository of information on Antarctic penguin biogeography that contributes to a growing suite of applications of value to the Antarctic community.

Whole genome sequencing reveals stepping-stone dispersal buffered against founder effects in a range expanding seabird.

Many species are shifting their ranges in response to climate-driven environmental changes, particularly in high-latitude regions. However, the patterns of dispersal and colonization during range shifting events are not always clear. Understanding how populations are connected through space and time can reveal how species navigate a changing environment.

Big Mistake: Knowing and Doing Better in Patient Engagement.

Pushing back on policies favored by dying patients is a challenging endeavor, requiring tact, engagement, openness to bidirectional learning, and willingness to offer alternative solutions. It's easy to make missteps, especially in the age of social media. Holly Fernandez Lynch shares her experience learning with and from the amyotrophic lateral sclerosis (ALS) community, first as a caricature of an ivory tower bioethicist and more recently as a trusted advisor, at least for some.

Objectives: The purpose of this systematic review is to explore the impact of self-referral and direct access pathways on inequalities in health care use.

Raising the 'environmental question' in social work in Canada and Scotland.

This article contributes a comparative review of social work in Canada and Scotland to international conversations about social work and the environment. The 'environmental question' of the 21st century is a radical challenge to social work developed in relation to the 'social question' of the 19th century. Work to begin to include the natural environment within high-income state social work can expect to encounter established infrastructures of thinking and doing that will be difficult to shift.

Preclinical Evaluation of Zn(II) Self-Assemblies with Selective Cytotoxic Activity Against Cancer Cells In Vitro and In Ovo.

Dipodal pyridylthiazole amine ligands L and L both form different metallo-supramolecular self-assemblies with Zn and Cu and these are shown to be toxic and selective towards cancer cell lines in vitro. Furthermore, potency and selectivity are highly dependent upon the metal ions, ligand system and bound anion, with significant changes in chemosensitivity and selectivity dependent upon which species are employed. Importantly, significant anti-tumor activity was observed in ovo at doses that are non-toxic.
