Intelligent Telemedicine Systems For Contactless Heart Rate Estimation Using Deep Learning-Based Rppg, Do Duc Thinh, Nguyen Duc Manh, Nguyen Thi Bich Ngoc, Vu Van Huan

Journal of Informatics and Web Engineering

Over the last ten years, telemedicine has undergone significant developments, from simple communication-based healthcare to smart and data-driven solutions. The solutions are now powered by Artificial Intelligence (AI), Machine Learning (ML), and Internet of Medical Things (IoMT) technologies. Physiological monitoring is traditionally done with contact-based sensors. The sensors include Electrocardiogram (ECG) and pulse oximeters. The sensors have various disadvantages, including hardware costs, difficulty in continuous usage, and discomfort for patients. Photoplethysmography (rPPG), a remote method of physiological monitoring, is a breakthrough technology. The method is used to estimate physiological signals, including Heart Rate (HR), from video streams captured by standard …

Why Student Research Matters: A Graduate Student’S Perspective, Jessica L. Hensley

The Journal of Integrative Physiology

Research fundamentally changes how students engage with knowledge. Rather than memorizing established facts, students learn to question, analyze, and contribute to the body of knowledge within their field (1). This shift supports deeper understanding and promotes critical thinking skills by encouraging active construction of knowledge (1). It also exposes students to the process of engaging with scientific literature and integrating information within the context of their research (2).

In my experience, research requires individuals to confront uncertainty. Experiments do not always produce exact results, and methods can require modification. Through this process, students develop adaptability, persistence, and the ability to …

The Possibility Of Post Binary Reflexivity: A Genealogy Of Binary Logic In Western Philosophy, Vaughan A. Bidois

Critical Humanities

This article traces a genealogy of binary logic within Western philosophy, from its origins in Platonic metaphysics through to its deconstruction in poststructuralist theory. Drawing on the genealogical methods of Friedrich Nietzsche and Michel Foucault, it critiques how oppositional structures, such as mind/body, reason/emotion, and truth/error, have persisted through shifting intellectual paradigms while shaping knowledge, power, and subjectivity. Structuralist and linguistic theories are examined for their role in reinforcing binary meaning-making, while poststructural critiques (notably Derrida and Foucault) are explored for their attempts to subvert such hierarchies. However, the article argues that these critiques remain paradoxically ensnared within the same …

Human Wisdom And Artificial Intelligence: Role Of Liberal Arts Education In A Neoliberal World, Purna Chandra Bhusal

Critical Humanities

Neoliberalism is an economic and political ideology that originated in the 1930s and 40s, gained momentum in the late 70s and 80s, and peaked in the 90s and 2000s. Since its inception, neoliberalism has promoted a free-market economy with minimal state intervention, granting individuals the freedom to compete and succeed. Since the last quarter of the twentieth century, the neoliberal system has invested in, incorporated, and promoted Artificial Intelligence (AI), valuing an AI-enhanced corporate ethos. As a result, the success of higher education is generally measured by the quantity of technologically sound, market-ready, AI-trained human capital it produces for industry. …

Why Literature Matters: Perpetrator Portrayal, Cultural Imaginaire And Poetry Of The Taliban, Inayat Ullah

Critical Humanities

The question of how perpetrators of violence are identified, represented and understood has become a central concern of Perpetrator Studies, an interdisciplinary field that emerged in the early twenty-first century. This article analyzes The Poetry of the Taliban in a bid to examine how the selected poems construct and negotiate multiple figurations of the perpetrator rather than presenting it as a singular or fixed category. While the poems frequently identify perpetrator through recognizable political, military and ideological structures, they also reveal the complexities involved in reducing the perpetrator to a clearly identifiable form or kind. In exploring these tensions, the …

Enhancing Access And Social Mobility: Metro State University's Liberal Arts Mission In Action, Kristen Lillvis, Kate Ries

Critical Humanities

This article examines how a liberal arts framework has guided Metropolitan State University’s responses to political, financial, and social pressures on higher education. Drawing on the university’s history as an access-oriented, urban institution, the authors present two case studies—the North Star Promise scholarship and emergency grant funding—to demonstrate how mission-driven investments in students’ basic needs advance social mobility and strengthen institutional sustainability. The authors argue that prioritizing student supports, including those available through short-term or contingent opportunities, yields long-term benefits for learners, their communities, and the university.

Evaluating The Impact Of Early Contractor Involvement On Enhancing The Performance Of Construction Projects In Egypt, Samah Saleh Abdelraof, Ayman Ahmed Ezzat Othman, Lamees Mostafa Ahmed

Mansoura Engineering Journal

The construction industry constitutes a critical pillar of Egypt’s national economic growth and sustainable development. Despite its strategic importance, the sector continues to face persistent challenges, including chronic cost overruns, schedule delays, and inadequate coordination among stakeholders. These inefficiencies are largely attributed to the dominance of the traditional Design–Bid–Build (DBB) system, which enforces a rigid separation between design and construction, fostering adversarial relationships and project disputes, which highlights the need for alternative procurement approaches. This research investigates the impact of Early Contractor Involvement (ECI) as a collaborative procurement alternative to enhance project performance. Case studies show that ECI improves early-stage …

From Principal To Behavioral Health Ceo: Lessons Schools Must Learn About Student Mental Health, Anthony S. Felder

Essays in Education

Schools across the United States are increasingly functioning as front-line mental health systems, often without adequate preparation, staffing, or clinical training. This essay draws on the author's lived experience as a former school principal, doctoral scholar in educational leadership, licensed clinical social worker, and current behavioral health chief executive officer to examine the intersection of K-12 education and youth mental health. Grounded in trauma-informed care, restorative practice, and family-centered systems of support, the essay presents five evidence-based lessons that school leaders must consider to meet students' evolving social-emotional needs. These lessons address the limitations of punitive discipline, the urgent need …

BACKGROUND: Patients presenting with bleeding or pelvic pain in early pregnancy are commonly found to have pregnancies of unknown location (PUL), with no sonographic findings of intrauterine nor ectopic pregnancy. We aimed to explore healthcare experiences and needs of patients presenting with PUL.

METHODS: This was a qualitative study using semi-structured interviews to explore healthcare experiences among patients with PUL. Patients were eligible if they presented with bleeding or abdominopelvic pain to the OB/GYN office or emergency department and were found to have a PUL followed in an electronic health record tracking list; had an initial human chorionic gonadotropin (hCG) …

Reclaiming Narrative Authority: Gendered Violence And Feminist Reauthorship In Sharon Pollock's Saucy Jack, Jennifer Jones Cavenaugh

Theatre and Dance Faculty Publications

This article examines Sharon Pollock’s Saucy Jack (1994) as a feminist intervention into the narrative structures that have sustained the cultural authority of Jack the Ripper mythology. Drawing on feminist historiography, particularly Judith Walkowitz’s analysis of male violence as narrative structure and Hallie Rubenhold’s reclamation of the murdered women’s lived histories, the essay argues that Ripper narratives depend on three interlocking conventions: killer-centered focalization, the erasure of women’s lives, and the aestheticization of death as spectacle. Through close performance analysis, the article shows how Pollock dismantles these conventions by centering Kate, a music hall actress whose reenactments transform performance into …

The Neuroprotective Effect Of Cdc42 Inhibition In The G93a Mutant Hsod1 Mouse Model Of Als, Andrea Koly

Undergraduate Theses, Capstones, and Recitals

Amyotrophic lateral sclerosis (ALS) is a progressive and fatal neurodegenerative disease characterized by the selective loss of upper and lower motor neurons, leading to muscle weakness, neuromuscular junction (NMJ) degeneration, paralysis, and eventual death due to respiratory failure. Despite extensive research, effective disease-modifying therapies remain limited, underscoring the need to identify novel molecular targets involved in ALS pathogenesis. Dysregulation of Rho family GTPases has been implicated in neurodegeneration, with Rac and Rho exerting opposing effects on neuronal survival; however, the role of the closely related GTPase Cdc42 remains poorly understood in ALS. In this study, the therapeutic potential of inhibiting …

Policy Solutions In The Ev Battery Supply Chain Addressing Unethical Social And Environmental Practices, Mateo Mazariego-Halpern

Undergraduate Theses, Capstones, and Recitals

California should adopt a phased supply chain accountability framework for electric vehicles sold in the state, combining the immediate implementation of a voluntary Fair Trade Decal program with the mandatory adoption of COFFEE (Corporate Operations Free From Environmental Evil) Standards based on CAFÉ standards, by 2035. This thesis identifies a critical gap in U.S. EV policy: current federal legislation regulates where batteries are sourced but not how cleanly or ethically they are produced. The consequences of this regulatory gap are severe, with emissions simply shifting further down the supply chain rather than being eliminated, child labor and indigenous displacement going …

Mothers’ Childhood Maltreatment And Developmentally Appropriate Attributions Of 12-Month-Old Infants, Katelyn M. Lamberton

Undergraduate Theses, Capstones, and Recitals

This study examined associations between developmentally appropriate attributions (DAAs), an understudied construct, with maternal history of childhood maltreatment and maternal reflective functioning (RF) with their 12-month-old infants. The study examined if 1) DAAs at 12 months were concurrently associated with parental RF at 12 months for construct validity, and 2) higher levels of maternal childhood maltreatment were associated with lower DAAs for predictive validity. Participants were 156 mothers (40.0% White, 25.5% Latinx, 14.9% Black, 5.5% Asian, 2.1% Native-American, 12.0% biracial/multiracial) and their 12- to 15-month infants. Childhood maltreatment and RF were assessed by parental self-report at three-months and 12-months postpartum …

Rapid-Prototyping Nanofabrication: Lcd-Based Projection Lithography And Physical Vapor Deposition, Sabeel Saleem Mohammmed

University Honors Theses

The semiconductor industry's continued growth, driven in large part by demand for artificial intelligence hardware, has highlighted the need for greater workforce development in regions adjacent to major fabrication centers like Oregon's Silicon Forest. This capstone project lays the groundwork for a small scale and student led semiconductor fabrication lab at Portland State University by demonstrating two of the core steps in chip manufacturing: photolithography and thin film deposition. Rather than relying on conventional fixed reticles, this work explores a unique, low cost approach to patterning that uses an ultraviolet-compatible liquid crystal display (LCD) as a programmable reticle, allowing arbitrary …

Esophageal Innominate Artery Fistula After Delayed Recognition Of Esophageal Foreign Body., Arianne J Abreu, Rahul Sinha, Robert T Sataloff

Otolaryngology (ENT) Resident Research

Esophageal innominate artery fistula (EIF) is a rare cause of life-threatening gastrointestinal hemorrhage. This condition occurs most often secondary to an aneurysm, tumor, or esophageal foreign body. After stabilization of airway and circulation, the management options vary from open to endoscopic and endovascular repair. The initial presentation, diagnosis and management of EIF in the literature focuses on adults primarily. In this case report, the clinical presentation of EIF in a pediatric patient, secondary to delayed recognition of a foreign body, highlights management considerations in this population.

Explaining Variation In Medical Aid In Dying Policy Across U.S. States, Abigail Hopper

Undergraduate Theses, Capstones, and Recitals

This paper asks why Medical Aid in Dying (MAiD) policy in the United States does not follow a simple partisan pattern between states. Existing scholarship on morality policy emphasizes ideological conflict and partisan alignment, but this framework cannot fully explain why states with similar political compositions have adopted different MAiD policy outcomes, indicating that some key mechanisms shaping the variation have been overlooked. To address this, this paper combines a national dataset of MAiD policies across all fifty states with a comparative case study of Montana, Colorado, and West Virginia, focusing on differences in institutional venues, framing strategies, and coalition …

Differential Roles Of Moesin And Vasp In Β-Catenin-Associated Networks During Zebrafish Heart Regeneration, Allen Rutman

Undergraduate Theses, Capstones, and Recitals

With cardiovascular disease remaining as the leading cause of mortality worldwide, it is largely due to the limited regenerative capacity of the human heart. However, zebrafish (Danio rerio) can fully regenerate cardiac tissue following injury, providing a valuable model for studying the mechanisms of heart repair. To investigate these mechanisms, we used proteomics methods in the past. Proximity labeling is a technique that identifies proteins based on their physical proximity to a protein of interest. It can be applied in organisms and in living cells (Roux et al., 2012; Cho et al., 2020). We used proximity labeling to characterize protein …

Welsh, British, And Argentine: Identities Of Convenience In The Welsh Colonies Of Patagonia, Benjamin Welch

Undergraduate Theses, Capstones, and Recitals

In this thesis, I examine the Welsh colonies in Patagonia (in Welsh, Y Wladfa) and how the Welsh negotiated their complex identity. Founded in 1865 as a nationalist project intended to preserve Welsh language, culture, and religion, the colony faced extreme hardships and was forced to ask for help. Drawing on British, Welsh and Argentine sources, I argue that Welsh colonists adopted a pragmatic approach to identity, emphasizing their Welshness, Britishness, or Argentinity as needed. While this flexibility was necessary for the colony to survive, it undermined the original goal of a Welsh homeland free of outside influence. Ultimately, the …

Industrial Democracy: Unionization, Power, And Control In Rockefeller’S Southern Colorado, Ava Welty

Undergraduate Theses, Capstones, and Recitals

By 1914, democracy was clearly connected to America’s political ethos, and Wilson and Frank Walsh only amplified the term. Against this backdrop, labor and CF&I sought to define their movement as aligned with the national project of industrial democracy, despite having divergent understandings of the term. CF&I and Rockefeller built upon decades of social betterment, in addition to new ideas of company unionism to create their definition of industrial democracy, while workers returned to union recognition as a tool of power to construct their definition of industrial democracy. This paper argues that conflicting definitions of industrial democracy after the Ludlow …

A Novel, Embedding-Based Approach To Longitudinal Survey Data Imputation, Julia Rezvani

University Honors Theses

Longitudinal surveys are ubiquitous in the social sciences as a means of tracking changes in behavior and opinions with time and identifying potential causal mechanisms. These surveys are frequently plagued by missing data and semantic drift, both of which limit their effectiveness and scientific utility. Imputation algorithms allow researchers to fill gaps in collected survey datasets, imperfectly reconstructing lost data. Although deep learning algorithms have been used in imputation to great success, approaches which simultaneously leverage the semantic and temporal structure of longitudinal surveys have not yet been developed. We propose a novel imputation architecture which is capable of leveraging …

School of Nursing & Midwifery, East Africa

Background: Noncommunicable diseases (NCDs), particularly cardiovascular diseases (CVDs), hypertension and diabetes, are major contributors to morbidity and mortality globally and in Rwanda, where the dual burden of HIV and NCDs is increasing. Evidence remains limited on how biological, behavioural, social, environmental and health-system determinants influence cardiovascular and metabolic outcomes among people living with HIV (PLHIV) in Rwanda. The NCOHIRWA cohort was established to prospectively investigate determinants associated with CVDs, hypertension, diabetes and related NCD outcomes among PLHIV, newly diagnosed PLHIV and people without HIV (PWoH). This manuscript presents the protocol for the NCOHIRWA cohort study.

Methods:  The NCOHIRWA study …
