    A critical review of pre-post surveys designed to measure student epistemology in undergraduate science courses
    (2025-11-18) Chatzikyriakidou, Kyriaki; Hall, Kristi L.; Redish, Edward F.; Cooke, Todd J.
    The epistemology of science students, i.e., their beliefs about the nature of the knowledge they are learning, about what they have to do to learn it, and about how they will use that knowledge, often plays a powerful role in what they learn in their science courses. This perspective paper provides a broad overview of the theoretical frameworks, designs, and applications of online pre-post surveys that are available to assess the potential shifts in epistemic perspectives in undergraduate science courses. We pay particular attention to a recent survey for biology courses called the Maryland Biological Expectation Survey (MBEX). The MBEX was developed to probe four epistemic themes that are closely aligned with the Vision and Change initiative for reforming undergraduate biology education. This review is intended to inform STEM teachers about the availability of online epistemological surveys for evaluating the epistemic effects of their courses. These surveys can also help STEM education researchers readily evaluate how different pedagogies, classroom contexts, and other features of learning environments affect the epistemic perspectives of science students.

    Search "Libraries Worldwide" with Primo VE
    (2025-11-14) Bradley, Benjamin
    Change will almost always ruffle some feathers. My institution recently migrated from WorldCat Discovery to Alma/Primo VE, and we received a lot of feedback lamenting the loss of WorldCat Discovery. This wasn't just people resistant to change, the system migration disrupted users' normal workflows. As a library focused on "just in time" services, Interlibrary Loan is an essential for many of our users. Primo VE can integrate with WorldCat, but during our migration we were discouraged to implement the integration because it causes performance issues. At most the suggestion was to create a separate search option in Primo VE to just search WorldCat, yet that would similarly complicate the research workflow. In response to the volume of feedback, I began a month-long test of the API integration, and I found that the integration did not cause performance issues. This poster will share the data I collected, the methods used, and a discussion about the pros and cons of integrating the WorldCat API as part of the default search option in Primo VE.

    Understanding Linkages Between Coastal Environment & Community Health
    (2025-01-24) Vargas-Nguyen, V; Kelsey, Heath; Badri, L; Adebayo, A; Breton, T; Byun, J; Fife, A; Kalama, I; Matthew, L; Novara, A; Sequeira, R
    Coastal environments face unique challenges that profoundly affect human well-being. Stressors such as pollution, rising temperatures, flooding, harmful algal blooms (HABs), and emerging contaminants threaten ecosystems and disproportionately impact vulnerable communities. This report presents the findings from the Fall 2024 Coastal Environment and Community Health course, by graduate students in the Marine, Estuarine, and Environmental Science program at the University System of Maryland.

    Genetic diversity, recombination and cross-species transmission of a waterbird gammacoronavirus in the wild
    (Journal of General Virology, 8/17/2023) François, Sarah; Nazki, Salik; Vickers, H., Stephen; Fournié, Guillaume; Perrins, M., Christopher; Broadbent, J., Andrew; Pybus, G., Oliver; Hill, C., Sarah
    Viruses emerging from wildlife can cause outbreaks in humans and domesticated animals. Predicting the emergence of future pathogens and mitigating their impacts requires an understanding of what shapes virus diversity and dynamics in wildlife reservoirs. In order to better understand coronavirus ecology in wild species, we sampled birds within a coastal freshwater lagoon habitat across 5 years, focussing on a large population of mute swans ( Cygnus olor ) and the diverse species that they interact with. We discovered and characterised the full genome of a divergent gammacoronavirus belonging to the Goose coronavirus CB17 species. We investigated the genetic diversity and dynamics of this gammacoronavirus using untargeted metagenomic sequencing of 223 faecal samples from swans of known age and sex, and RT-PCR screening of 1632 additional bird samples. The virus circulated persistently within the bird community; virus prevalence in mute swans exhibited seasonal variations, but did not change with swan age-class or epidemiological year. One whole genome was fully characterised, and revealed that the virus originated from a recombination event involving an undescribed gammacoronavirus species. Multiple lineages of this gammacoronavirus co-circulated within our study population. Viruses from this species have recently been detected in aquatic birds from both the Anatidae and Rallidae families, implying that host species habitat sharing may be important in shaping virus host range. As the host range of the Goose coronavirus CB17 species is not limited to geese, we propose that this species name should be updated to ‘ Waterbird gammacoronavirus 1 ’. Non-invasive sampling of bird coronaviruses may provide a tractable model system for understanding the evolutionary and cross-species dynamics of coronaviruses.
