Ice Giant Watch Dog: Cubesat Concept To Monitor Weather On Neptune, Isabela Huckabee, Don Banfield, Nikole Lewis, Elijah Mullens, Abby Boehm

Small Satellite Conference

Why Neptune?

Neptune hosts one of the most dynamic weather systems in the solar system, yet it hasn't been closely observed since the Voyager-2 flyby. Existing observing programs [1,2] are too infrequent to capture the day-to-week timescales on which storms and clouds evolve, but a dedicated CubeSat could fill this gap.

The current project has two goals:

  1. Explore the photometric precisions achievable by a CubeSat platform
  2. Determine whether the presence of clouds will be detectable by a CubeSat platform

Small Satellite Conference

Reliance on fossil fuels, combined with the physical limits of ground-based solar arrays, makes a strong case for collecting solar energy in orbit. Earth intercepts roughly 1.4 kW/m² at the top of the atmosphere, but absorption by carbon dioxide and water vapour and atmospheric scattering cut peak surface intensity to about 1.1 kW/m², this results in an over a 20% reduction. While inclination, time of day, and weather restrict that to a narrow band of land for a few hours each day.

The Solar Incident Energy Relay Array (SIERA) is a proposed mission that will create a single 6U CubeSat …

Quality Reveals What Quantity Conceals: Deceptive Equity Patterns In Urban Green Space Distribution, Zheng Xian, Yoshiharu Suzuki, Kun Liu, Clive E. Sabel, Naoki Nakaya, Atsushi Hozawa, Tomoki Nakaya

School of Geography, Earth and Environmental Sciences

Equitable provision of urban green space depends on how green space exposure is measured, yet aggregate, quantity-focused metrics can mask disparities in quality. We introduce the concept of deceptive equity, in which apparent distributional fairness conceals substantive inequality, and test it across 344 postcode areas in Sendai, Japan. Across three dimensions — ecological (NDVI), perceptual (Green View Index) and service provision (accessible park count) — we paired a quantity indicator with a quality indicator. A quantity–quality divergence emerged in every dimension: wherever a quality indicator showed a significant socioeconomic gradient it favoured affluent areas, whereas the corresponding quantity indicators were …

Building Competency Through Context: A Simulation-Driven Curriculum Redesign, Natalya Pasklinsky, Mary T. Hickey, Kristy Deyeso Aug 2026

Building Competency Through Context: A Simulation-Driven Curriculum Redesign, Natalya Pasklinsky, Mary T. Hickey, Kristy Deyeso

International Nursing Research Congress (INRC)

Background: Traditional nursing curricula often emphasize isolated psychomotor skill instruction, limiting retention and transfer to complex clinical settings. Previously, students completed a three-hour skills lab followed by a single three-hour simulation. Faculty observed that, even immediately after the skills session, learners struggled to apply those same technical skills in simulation. During “double-day” sessions, both sequencing approaches produced similar performance gaps, revealing a misalignment between knowledge, skills, and reasoning, highlighting the need for a simulation-centered redesign to support contextual skill application.

Purpose: This project aimed to redesign the simulation curriculum to align with AACN Essentials (2021), advancing a competency-based framework emphasizing …

International Nursing Research Congress (INRC)

Posttraumatic stress disorder (PTSD) may develop after a traumatic event and may impair cognition, mood, behavior, and increase risk of psychiatric illness and suicide (Mann et al., 2024). The lifetime prevalence of PTSD among United States (US) veterans can reach 29% depending on their period of military service (Judkins et al., 2020; Na et al., 2023). Many veterans still do not seek treatment. In a study of 13,824 veterans, less than 50% received PTSD treatment in the year after diagnosis (Grekin et al., 2021). Limited awareness of PTSD treatment options may be a cause. The aim of this dissemination initiative …

Decolonizing Peer Review: Dismantling Epistemic Gatekeeping In Nursing Scholarship, Kechi Iheduru-Anderson Aug 2026

Decolonizing Peer Review: Dismantling Epistemic Gatekeeping In Nursing Scholarship, Kechi Iheduru-Anderson

International Nursing Research Congress (INRC)

Background: Peer review in nursing privileges Western knowledge systems while marginalizing Indigenous, Global South, and community-based traditions. This colonial structure limits who contributes to nursing science, which methodologies are legitimate, and constrains culturally responsive care. Current practices exclude nurse researchers employing non-Western epistemologies, working in non-English languages, or prioritizing community-based approaches essential to addressing health disparities.

Purpose: This presentation examines peer review as a colonial mechanism and advocates for reforms democratizing nursing knowledge production. It explores how linguistic hegemony, methodological gatekeeping, and citation politics perpetuate epistemic injustice, and identifies alternative models from Latin America, Africa, and Indigenous communities fostering collaboration …
