Journal of Mechanical Engineering Science and Technology (JMEST)

The use of ethanol-blended fuel in a standard vehicle can reduce combustion quality, which has an impact on decreasing vehicle performance. At the above 20% blend level, it affects vehicle performance and requires adjustments to engine settings or the Electronic Control Unit (ECU) before use on conventional engines. This study investigates the effect of aftermarket ECU settings on the performance of a 150 cc motorcycle operating on a gasoline-ethanol blend. Four fuel variations were tested: Pertalite (P100), revvo 90 (R100), and 30% ethanol blends (PE30 and RE30). This study analyzes the effects of optimizing injection duration and ignition timing settings …

Out Of The Briar Patch: Storying Resistance Among Black Male Survivors Of Childhood Sexual Abuse And Its Impact On Their Educational Experiences, Anthony Animuntu

Dissertations

This study examines the lack of support within educational settings for Black boys who are survivors of childhood sexual abuse (CSA). Despite growing attention to trauma-informed practices, the experiences of Black male survivors remain largely absent from educational research. Using a qualitative, phenomenological approach informed by critical autoethnography, semi-structured interviews were conducted with five African American men reflecting on their schooling experiences as CSA survivors. Axial analysis revealed four central themes: silence as survival and strategic invisibility, shame and internalized distress, institutional misrecognition, and the transformative role of relational care and educational kinship. Findings indicate that participants’ trauma was often …

Can Curriculum Improve Confidence? Examining The Impact Of The Implementation Of The California Math Framework On Math Anxiety Levels Of Preservice Teachers In California, Amanda Lubbs

Dissertations

In 2010, the state of California adopted the Common Core State Standards (CCSS) as an effort to ensure students were graduating high school as college and career ready. Shortly after, in 2013, the California Board of Education adopted the California Math Framework (CMF) as a tool for schools to implement the CCSS for Mathematics (CCSSM). Its recommendations incorporated research-based techniques to alleviate math anxiety through the use of explorative learning experiences that help students understand math skills in applied contexts, and by de-emphasizing rote practice and memorization. This study inquires about the framework’s effectiveness in mitigating math anxiety among pre-service …

Rethinking Learning From Incidents In Healthcare: A Safety-Ii Model Integrating Work-As-Imagined, Work-As-Done, And Work-As-Experienced, Nawal Khattabi, Axel Ros, Matt Carey, Aled Jones

School of Nursing and Midwifery

Healthcare organizations increasingly investigate patient safety incidents using systems thinking. However, even investigations that claim to adopt a systems approach frequently revert to linear, event-focused reasoning concluding on deviations and recommending further training. A foundational question remains unresolved: when an incident review identifies a "deviation", does this represent exceptional behavior or the system's typical mode of operation that generally succeeds under varying conditions but occasionally fails? Without this distinction, explanations for incidents tend to focus on individual non-compliance rather than understanding the everyday adaptations that enable care delivery in a complex adaptive system. Consequently, incident reviews that promote system learning …

Embedding Nursing Student Researchers In Health System Change: Insights From An Ontario Health Team, Adam Bursey, Izzar Linares, Rosanra Yoon

International Nursing Research Congress (INRC)

Background: Embedding nursing students as researchers within health systems provides meaningful opportunities for experiential learning and mutual capacity building (Menzies et al., 2021). Students gain hands-on experience navigating interdisciplinary environments, while health system partners benefit from added analytic support and strengthened academic connections (Menzies et al., 2021). Despite its value, opportunities for nursing students to participate in embedded research remain limited and are shaped by program structures and funding availability (Corbett et al., 2023). Expanding such experiences is essential to prepare future nurse leaders with the competencies needed to address complex health system challenges (Slattery et al., 2016). This reflexive …

Communication Innovation: Developing A Bilingual Communication Board Validated By Lawshe’S Cvr, Natalie Palau, Amy Valenta

International Nursing Research Congress (INRC)

Hospitalized families with Limited English Proficiency (LEP) can encounter communication barriers during routine interactions due to limited interpreter access, increasing the risk for adverse events and reducing satisfaction. At a freestanding pediatric hospital neurology unit, 67.3% of nurses reported difficulty communicating basic needs and 60% felt dissatisfaction with current LEP communication methods. To address these challenges and enhance communication, a bilingual communication board, featuring English and Spanish captions alongside illustrative icons, was developed and validated.

Advancing Global Health Equity Through Co-Produced Hypertension Care In Rural Ghana, Sandra Peniston

International Nursing Research Congress (INRC)

Introduction: Hypertension, often called the “silent killer,” is a leading cause of preventable death and disability from non-communicable diseases (NCDs) worldwide. Its disproportionate burden in low- and middle-income countries highlights global health inequities, where limited access to primary care, diagnostics, and long-term management perpetuates avoidable suffering. In Ghana’s rural Savannah Region, hypertension often remains undiagnosed and uncontrolled. The Co-Produced Hypertension Adult Intervention (CO-HEART) addresses this inequity by strengthening primary health care (PHC) through a community-and provider-driven, context-specific approach.

Methods: Guided by Participatory Action Research, decolonising principles, and the Six Steps in Quality Intervention Development framework, CO-HEART engaged nurses, clinicians, district …

Virtual Reality Simulation For End-Of-Life Communication: Case Development And Pilot Implementation, Kathryn M. Ledwin, Kylene Abraham, Karen Parker

International Nursing Research Congress (INRC)

Background: Registered nurses have reported feeling unprepared and lacking proper skills for critical end-of-life discussions with patients and their families (Kerr et al., 2020). Virtual reality (VR) simulation presents a novel approach to providing immersive opportunities to support learning and skill development (Liu et al, 2023; Sinurat et al.,2025).

Purpose: This project aimed to develop and examine the feasibility of using VR simulation as an educational intervention …

The Possibilities Of Constitutional Education, Mark Jia

Georgetown Law Faculty Publications and Other Works

Constitutional scholarship has traditionally focused on formal constitutional actors: courts, legislatures, and executives. These actors are often regarded as primary sources of constitutional law, or in some cases, as final arbiters of constitutional meaning. More peripheral in this literature are actors thought to transmit what courts and high officials have established. These constitutional educators, including law professors, legal journalists, and civics planners, are often overlooked for defensible reasons: They lack the normative authorities of formal institutional actors, and they do not exercise power as it is often understood in public law.

This Article advances a general theory of constitutional education …

Judges, Speaking Of Death: Criminal Sentencing As A Socio-Cultural Practice In India’S Trial Courts, Ashna Devaprasad

Socio-Legal Review

What role does language play in legitimising the exercise of judicial discretion during sentencing? And what can a judge’s linguistic choices tell us about the wider sentencing culture of a criminal justice system? Sentencing outcomes have long attracted considerable attention in criminal law scholarship, but the process of sentencing – the logics judges use, the narratives they construct, and the audiences they seek to persuade – has received much less empirical scrutiny. Building on ideas from “law and culture” and organisational sociology literature, this Article proposes studying sentencing as a “socio-cultural” practice; one that qualitatively examines the judicial function of …

Development Of Proposed Airworthiness Certification Criteria For Interference-Tolerant Radio Altimeter Systems, Matheus B. Furstenberger

Student Works
