Journal of Maine Medical Center

Problem: Microaggressions negatively impact the mental health and wellness of patients and health care workers. Despite efforts in medical education to address this issue, there is limited research on the effect of these strategies in clinical settings over time. We evaluated how a workshop on navigating microaggressions impacts medical students 1 year after the workshop.

Approach: A 60-minute workshop on microaggressions was implemented for medical students (n=85) across 3 clerkship sites. The workshop focused on identifying, responding to, and debriefing microaggressions as recipients or bystanders using a toolkit. Post-intervention surveys measured students’ satisfaction and perceived ability to navigate microaggressions. One …

Uncoupling Agents As A Contributor To Refractory Metabolic Acidosis In A Burn Victim: A Case Report, Kelsie M. Lynch

Linking Shoreline Change, Environmental Forcings, And Sedimentological Resilience In Nourished Beaches Of Cape May And Wildwood, New Jersey, Usa: A Multi-Decadal Synthesis, Divomi Balasuriya, Greg Pope

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Beach nourishment is a widely used strategy to mitigate coastal erosion, yet its long-term geological impacts remain poorly understood. This study provides a multi-decadal synthesis of shoreline change and sedimentological evolution on the nourished beaches of Cape May and Wildwood, New Jersey, USA. Using shoreline positions from 1991 to 2024, we identify contrasting trajectories: Wildwood exhibits ‘persistent transition’ with severe northern erosion (EPR: −10.0 m/yr) feeding southwards accretion, while Cape May demonstrates a ‘managed equilibrium’ with widespread accretion (mean EPR: +1.15 m/yr). Wave energy correlations account for less than 15% of shoreline variability, indicating natural drivers have been superseded by …

A Systematic Study Of Passkey User Experience Consistency, Bernhardt Ramat

Theses and Dissertations

Passkeys have emerged as a more secure authentication method than passwords, providing a passwordless alternative resistant to phishing and credential theft attacks. Despite their growing adoption, a systematic study into the user experience of passkeys across various websites has yet to be conducted. Usability heuristics suggest that users transfer their expectations from one product to another, and therefore, inconsistencies in passkey deployments can increase cognitive load, resulting in frustration and possible rejection. To address this knowledge gap, this paper presents a comparative analysis of the external functional consistency of the passkey user experience across 111 websites. Our research reveals that …

Likewise, multiliteracies continues to make headway in conversations about pedagogy. Research continues to delve into both as practices, though the creation of practical suggestions for educators grounded in data is still in its infancy. There …

Assessing Multilingual Learners: Necessary Reforms In Language And Literacy Evaluation, Victoria Gibson

Honors Program Theses and Projects

Assessing multilingual learners can look different for every student, teacher, and school. Assessing multilingual learners presents challenges because traditional tools often fail to capture students’ true abilities, with scoring inconsistencies, cultural bias, and teacher assumptions further affecting outcomes. Early identification tools, like the frequently used Home Language Survey used by Salerno and Andrei (2024), can misclassify students, impacting placement and support. Research highlights more equitable alternatives, such as formative, classroom-based, and culturally responsive assessments, that better reflect students’ full linguistic abilities and promote fair, accurate evaluation.
