Illuminating Hemophilia: Distinguishing Normal And Factor Deficient Plasma Clots Via Brightfield Microscopy And A Convolutional Neural Network, Jason H. Tullis

Undergraduate Honors Theses

When blood vessels are damaged, clots formed by the protein fibrin stabilize platelets and stem active bleeding. Coagulation, the physiological process that forms fibrin clots from blood plasma, hinges on the clotting cascade, a complex network of interacting proteins. These so-called clotting factors help control fibrin polymerization and thereby coagulation. A clotting factor deficiency generally slows coagulation, resulting in bleeding disorders like hemophilia A, B or C. Diagnosing the deficient factor's identity is essential to optimal treatment. Currently, missing factors are determined in reference laboratories via specialized tests. A more accessible test could help streamline the diagnosis process--in this work, …

Steptrigger: Contact-State-Triggered Backdoor Attacks On Vlm-Powered Legged Robots, Jiageng Zhang, Doniyorkhon Obidov, Kaichen Yang

Michigan Tech Publications

Large language models and vision-language models are increasingly used as high-level planners in robotic systems, using task goals and sensor summaries to select navigation or manipulation actions. This creates a new backdoor surface: a compromised planner can behave normally in most runs, yet change its target selection when a hidden trigger is present. Prior attacks on LLM-powered or embodied agents mainly rely on triggers that appear in language, camera-visible objects, scene semantics, or specific sequences of past actions. This paper presents StepTrigger, a contact-state-triggered backdoor attack for VLM-powered legged robots. The trigger is not a prompt token or a visible …

Improving Recognition And Communication Of Early Patient Condition Changes Through An Evidence-Based Staff Education Program, Raymond Mwanje

Walden Dissertations and Doctoral Studies

This doctoral project is a staff education project aimed at enhancing recognition and communication of early changes in patients' conditions in a long-term care rehabilitation environment. Delayed recognition of patient deterioration is a major challenge in nursing practice, as subtle changes in a patient's condition may go unnoticed, leading to delayed intervention, avoidable complications, and unnecessary hospital transfers. Poor communication among staff can also hinder the escalation of care, impacting patient safety and quality of care. There is evidence that structured communication strategies and education interventions can help enhance communication between clinicians and aid earlier detection of patient deterioration.

Reducing Hospital-Acquired Pressure Injuries In Acute Care Using Structured Prevention Strategies, Yemisi Adesuyi Akinfenwa

Walden Dissertations and Doctoral Studies

Pressure injuries that patients develop while hospitalized continue to be a major safety concern in hospitals treating very sick patients. These wounds hurt, make infections more likely, keep people in the hospital longer, and increase expenses. On many units, the steps meant to stop these injuries, like checking each patient's risk level and turning patients regularly are not carried out the same way for everyone. Because of this inconsistency, some patients develop preventable pressure injuries. The purpose of this Doctor of Nursing Practice (DNP) project was to create a clinical practice guideline (CPG) for organized pressure injury prevention and to …

Impact Of Taped Problems Intervention Modification On Children With Deafness, Clyniece Hodge

Electronic Theses and Dissertations

Children with hearing loss are at an increased risk of experiencing setbacks in various areas of life, including academic performance and employment opportunities. Academically, they are likely to experience poor academic achievement in reading, as well as in mathematics (ASHA, 2013). In comparison to gifted hearing students and average-ability hearing students, students with hearing loss are at a higher risk of low mathematics performance (Hassan & Mohammed, 2019). Despite these known challenges and risk factors, limited research has been conducted to identify effective intervention strategies for improving mathematical outcomes among this population. As such, this study aimed to evaluate the …

Dialogic Communication Ethics As A Hopeful Response To Artificial Intelligence, Kristen Haldeman

Electronic Theses and Dissertations

Within the past five years, a new technology has dominated modern culture: artificial intelligence. With a multiplicity of ways to respond to this new environment, this dissertation situates a response to artificial intelligence by combining the media ecology and communication ethics perspectives. Media ecology explores historical roots and biases of technology to learn about their influence of humanity. A dialogic communication ethics seeks to find an opening for hope to emerge. Hope, grounded in the works of Jacques Ellul and the Christian tradition, offers a new rhetorical perspective by shifting focus away from technology and to our neighbor.

The present study sought to evaluate the effectiveness of Behavior Skills Training (BST) in teaching core NDBI skills to a preschool teacher, examine changes in teacher self-efficacy related to supporting autistic students, and assess the …

Empathetic Political Communication As The Political Identity Of Female Legislators: A Phenomenological Study In The Surabaya City Dprd, Nurannafi Farni Syam Maella, Farida Farida, Herlina Harsono Njoto, Hamizah Sahharon, Vinna Amalia

JURNAL KOMUNIKASI INDONESIA

Politics has long been constructed as a masculine arena dominated by discourses of power, authority, and instrumental rationality. The presence of female legislators disrupts this hegemony by foregrounding empathetic modes of political communication that emphasize inclusivity, relational engagement, and responsiveness to social realities. These communicative practices not only contest dominant masculine norms in political discourse but also expand deliberative spaces and support the formulation of gender-responsive public policies. Accordingly, this study examines how female legislators in the Surabaya Legislative Council construct and enact empathetic political communication as a core expression of their political identity. Using a qualitative phenomenological approach, this …

From Theory To Practice: Locating Moral Exemplars In Aristotelian Virtue Ethics, Joseph A. Murray

McNair Summer Research Program

Abstract

This research examines mentorship within Aristotelian virtue ethics. Aristotle holds that moral excellence develops through habituation, guided practice that forms stable dispositions, rather than through knowledge or rules alone. Central to this process are virtuous mentors who model good character and cultivate practical wisdom (phronesis). Although Aristotle stresses the necessity of such examples, he offers little practical guidance on who they are or how they may be identified. This omission raises a practical challenge: if virtue depends on guidance from the genuinely virtuous, identifying those individuals is essential to the theory’s implementation.  My research investigates whether society provides accessible …

Navigating Errors: Voice Assistants And Aging Users, Bea Marithe V. Pulido

Theses

This study examined how age relates to usability, cognitive load, and affect when using voice-user interfaces (VUIs). VUIs such as Siri, Alexa, and Google Home are increasingly common and allow users to complete tasks through voice commands. While these systems can be convenient and accessible, especially for older adults, they often provide brief or unclear feedback when errors occur, making it difficult for users to understand what went wrong and how to continue the interaction. The current study compared older and younger adults (n = 40) to examine group differences in perceived usability, cognitive load, and affective change during VUI …

The Effects Of Predator-Prey Interactions On Carbon Sequestration In Philippine Grazing Halos, Alexandra Butler

All HCAS Student Capstones, Theses, and Dissertations

Predator presence can cause indirect shifts in prey behavior and composition (fear effects), inducing behaviorally mediated trophic cascades (BMTCs) that alter seagrass structure and associated carbon stores. Grazing halos have been identified as indicators of BMTCs and carbon storage due to formation linked to predator-mediated constrained herbivory. Here, I investigated the effects of predator community composition on reef fish communities, foraging behavior, seagrass structure, and their relationship to organic carbon (OC) stocks at varying levels of risk (i.e., within and outside of the halo). This study was conducted across 10 grazing halos in Tubbataha Reefs Natural Park, Philippines— providing a …

Visions of Research in Music Education

In response to the inequities within music education, Critical Race Theory (CRT) offers an approach to analyzing how race and racism operate within music education and prompts educators to critically examine existing structures and practices. CRT is a comprehensive framework that offers fundamental insights, perspectives, methods, and pedagogical approaches. Its primary objective is to identify, analyze, and transform the structural and cultural factors that perpetuate the marginalization and subordination of People of Color. CRT’s origins can be traced back to the legal system, where it emerged as a means to challenge and dismantle the pervasive influence of race and racism …

Professionalizing Folklore In Latin America: Four Paradigms Of The Musician And The Coloniality Of Music Education, Matias Recharte

Visions of Research in Music Education

In this article, I discuss the professionalization of folklore and its entanglements with coloniality through an analysis of four paradigms of the musicians I encountered in conversations with students, administrators and instructors at the Escuela Nacional de Folklore Jose Maria Arguedas in Lima, Peru. I contrast two pairs of paradigms, the empírico with the académico and the chivero with the professional in order to show how the “professional folklore musician” is constructed through similarities and differences with these paradigms. For my analysis, I use a coloniality theory framework (Casto-Gomez, 2021; Quijan, 1980, 2000, 2007; Segato 2011, 2022) which considers social …
