Cannibalism, Predation, And Refuges Of Juvenile Blue Crabsfrom A 37–Year Experiment, Anson H. Hines, Margaret A. Kramer, Kimberly D. Richie, L. David Smith, Robert Aguilar, Matthew B. Ogburn, Eric G. Johnson, Gregory M. Ruiz

Biological Sciences: Faculty Publications

This 37-y record (1989–2025) of field experiments tested seasonal and annual variation in predation on juvenile blue crabs (Callinectes sapidus) in a representative mesohaline site of Chesapeake Bay, USA, where the species is a dominant epibenthic predator and major fishery. We used replicated sets of individually tethered crabs to provide a relative index of lethal and sublethal predation rates on intermolt individuals as a function of size and habitats. Cannibalism by large adult crabs accounted for>97% of predation of juvenile crabs; predation by fish was not observed; and mortality from physiological stress was rare (< 1%). Sampling by depth showed that juveniles occurred in nearshore shallows, while adults were in deeper water. Cannibalism was also depth-dependent: Rates were high at 75 cm depth; intermediate at 40cm; and lowest at 15 cm shallows, which provided partial refuge. Cannibalism was size-dependent: 30 to 50 mm juveniles experienced high rates of predation; 90 to 110mm preadults had low rates; and >120 mm adults …

School of Biological and Marine Sciences

Illegal, unreported, and unregulated (IUU) fishing poses a significant threat to fisheries sustainability, global food security, and biodiversity conservation. Many regions rely on patrol-based enforcement to promote compliance, yet the effectiveness of such strategies in deterring IUU activity remains underexplored. In this study, we employed a mixed-methods approach to assess the impact of management and policy decisions on illegal fishing within the Chagos Archipelago marine protected area (MPA). This MPA has maintained near-continuous patrols since its implementation in 2010, providing a unique opportunity to evaluate the influence of patrolling on illegal fishing deterrence. First, we analyzed semi-structured interviews with fishers …

We also accessed archived data from field campaigns in 2003, 2004, and 2017 in order to test whether a recent increase in the number of hurricanes impacting the region, five since August, 2017, may have significantly altered the seasonal dynamics …

From Answers To Understanding: Bridging The Gap Between Multiple-Choice And Open-Ended Questions, Kathleen A. Siren

Teaching and Learning in Communication Sciences & Disorders

Assessment is central to effective teaching, and the structure of exam questions significantly influences both learning and instruction. Multiple-choice (MCQ) and short-answer (SAQ) questions are widely used and frequently studied, each offering distinct advantages and limitations for formative and summative assessment. This study examined a modified multiple-choice format, multiple-choice questions with explanation (MCQwE), for which students selected an answer and briefly explained their reasoning. Designed to combine the efficiency of MCQs with the diagnostic value of open-ended responses, MCQwE were implemented in an undergraduate speech science course and compared to traditional MCQs and SAQs in terms of student performance. Findings …

Intergenerational Hypertension Transmission Before And After South Africa's Democratic Transition, Winfred A. Avogo

Faculty Publications – Sociology and Anthropology

Background: Apartheid's structural violence produced profound cardiovascular inequalities among Black South Africans through processes that accelerate biological aging ("weathering") and transmit health disadvantage across successive generations. Whether South Africa's 1994 political transition interrupted this intergenerational transmission remains unknown. This study tests whether parent-to-offspring hypertension transmission weakened among cohorts born after apartheid's end, using the 1994 transition as a natural experiment. Methods: This study analyzed 30,438 parent-offspring dyads from five waves (2008–2017) of South Africa's National Income Dynamics Study, representing 11,655 unique offspring aged 18 years and older. Hypertension was defined as blood pressure ≥140/90mmHg or use of antihypertensive medication. Logistic …

Research outputs 2022 to 2026

Tasmanian devils (Sarcophilus harrisii), like all marsupials, give birth to altricial young. Here we employ proteomic analysis to identify components of devil pouch secretions that may contribute to offspring survival and development. Proteins were extracted from five samples and analysed by liquid chromatography-tandem mass spectrometry. Peptide-level evidence revealed proteins involved in a diverse set of immune pathways, including those mediating iron-ion transport, defence responses to bacteria, innate immune responses, and antigen processing. A core set of 200 proteins was identified across at least three samples, 63 of which were associated with antimicrobial or immunoregulatory functions. These included immunoglobulins, components of …

Why General Ai Inherited The Body: A Structural Account Of Embodied Modulation Under Monolithic Imitation, Griselda Poe

Publications and Research

General AI has pursued the replication of human-level intelligence without first decomposing human cognition into structurally distinct components. Human cognition, however, is shaped by embodied constraints such as mortality, survival pressures, finite lifespan, and physiological states. This paper argues that when cognition is treated as a single undifferentiated whole, embodied modulation is not accidentally introduced into AI systems but structurally entailed. Any attempt to imitate “human intelligence” under a monolithic model necessarily incorporates variability shaped by mortal embodiment. The tensions observed in contemporary AI systems are better understood as consequences of copying an undecomposed target rather than isolated implementation errors. …

Unveiling The Patent Landscape Of Biologic Drugs, Michael D. Frakes, Melissa F. Wasserman

Northwestern University Law Review

It is undeniable that the escalating price of biopharmaceuticals is a critical issue, as high prices limit patients’ access to life-saving medications and strain our healthcare system. Biologics, or large-molecule drugs, which are revolutionizing modern healthcare, are significantly contributing to the escalating cost of prescription drugs. While biologic drugs represent only 2% of all U.S. prescriptions, they comprise close to 50% of net drug spending.

Policymakers have proposed a series of interventions to decrease drug prices that target the patent practices of pharmaceutical firms. Yet due to differences in law, we have a robust source of patenting information for small-molecule …

Embodied Transcendence: Psychedelics And The Evolution Of Moral Abstraction, Emanuel Jas

Journal of Conscious Evolution

This paper explores the role of psychedelics in the context of evolutionary brain development and the conceptual capacity for moral realism. Drawing on theories from evolutionary anthropology, neuroscience, and moral philosophy, the first part provides a brief overview of human evolution and brain expansion. From here, recent empirical data from the neurosciences is assessed on the effect psychedelics have on the brain, along with speculations on the role of psychedelics in our hominoid evolutionary history—specifically, the capacity for phenomenologically rich, conscious, subjective experiences that are incredibly vivid and real. This imaginative capacity for transcendence and disembodiment could enable the realization …

Currently, there are very few efficient treatment options for hepatobiliary pancreatic cancer (HPC), which comprises pancreatic ductal adenocarcinoma (PDAC), biliary tract cancer (BTC), and hepatocellular carcinoma (HCC). The HPC tumors are the most lethal malignant tumors in the world. Traditional chemotherapy offers little survival benefit and is associated with notable systemic toxicity, which has made antibody–drug conjugates (ADCs) a hopeful treatment option. Strong cytotoxic drugs combine with monoclonal antibodies to attack tumor-associated antigens. This review discusses the benefits and current developments of Antibody–Drug Conjugates (ADCs) in treating HPC. It also covers their mechanisms of action, ongoing clinical trials, and the …

Speleoco: An Open, Low-Cost Arduino Co₂ Datalogger For Cave Microclimate Monitoring, Christos Pennos, Dimitrios Christaras

International Journal of Speleology

Carbon dioxide (CO₂) dynamics in caves are critical for karst processes, speleothem growth and dissolution, microclimate regulation, and caver safety. In cave atmospheres, CO₂ commonly derives from soil respiration, epikarst degassing, microbial activity, and, in tectonically active regions, deep-seated fault-related emissions. Fault-related CO₂ degassing may also track tectonic activity. However, continuous monitoring remains limited due to the cost and inflexibility of commercial instruments. Here we present an open-source, low-cost Arduino-based CO₂ datalogger designed for cave applications. The logger integrates a COZIR NDIR CO₂ sensor, a DS1337 real-time clock, microSD storage, and power-gating for extended deployment in humid environments. Firmware and …

Simulated Hearing Loss In Healthy Young And Older Adults Results In Poor Reaction Time In Older Adults., Victoria Kowalewski, Nicoleta Bugnariu, Rita M. Patterson, Jessica Hartos

Pacific Journal of Health

Emerging evidence links hearing loss to increased fall risk in older adults, yet mechanisms remain unclear. This study examined the impact of simulated hearing loss on reactive balance control in healthy young and older adults. Participants performed dual-task scenario involving auditory sentence repetition and unexpected surface translations. Hearing loss was simulated using Adobe Audition, applying frequency-specific attenuation based on moderate sensorineural hearing loss levels from the literature.

Speech-in-noise performance significantly declined under simulated hearing loss for both age groups (p < .001), confirming effective simulation, but not significant differences were found between age groups. Maximum COP-COM displacement (the scalar distance between Center of Pressure and Center of Mass) increased with perturbation intensity (Level 1 vs. Level 2: p < .001), but no significant differences were found between hearing conditions or age groups (p > .05), suggesting compensatory step execution was preserved.

Reaction time analysis revealed a significant interaction between hearing condition and perturbation level …
