Dynamically Adjustable Photoplethysmography Geometry Based On Perfusion Index And Motion Profile To Balance Accuracy And Power Efficiency, Hamed Vavadi, Kaiyuan (Kai) Yao, Chintan Trehan

Defensive Publications Series

Wearable photoplethysmography (PPG) sensors detect a small pulsatile signal against a large non-pulsatile background.  The signal quality varies widely across users, activities, and conditions.  This publication describes systems and techniques in which the optical geometry of a PPG sensor is adjusted during operation to balance signal quality against power consumption.  A voltage-controlled film, for instance, over an emitter and a photodetector changes an effective aperture, and thereby the depth of light penetration and the perfusion index, without moving parts.  A control system uses a perfusion index and a motion level to select the aperture size produced by the voltage-controlled film. …

Mexican Women Caregivers’ Support For Family Members With Type 2 Diabetes, Andrea Mesa

Walden Dissertations and Doctoral Studies

Type 2 diabetes (T2D) is a persistent public health challenge in the United States, disproportionately affecting Hispanic populations. Mexican-origin women often serve as primary caregivers for relatives living with diabetes, yet their voices and lived experiences remain underrepresented in research. This study addressed the limited understanding of how cultural values and caregiving roles influence diabetes management within Hispanic families. The purpose of this qualitative phenomenological study was to explore the lived experiences of Mexican-origin women aged 40 to 60 who care for a family member with T2D. Guided by the theory of planned behavior and social cognitive theory, the study …

Design And Characterization Of A 3d-Printed Dual Stacked Patch Antenna With Tunable Coupling For Uav Applications, Isabelle Lynn Brigman

Masters Theses

Antennas are a critical component of unmanned aerial vehicle (UAV) communication systems where compact size, light weight, and reliable operation across multiple frequency bands are critical. While microstrip patch antennas are attractive for UAV applications due to their low profile, low cost, and ease of fabrication, they are often limited by narrow bandwidth and fixed-frequency operation. To address these limitations, this thesis investigates a mechanically and electrically reconfigurable dual-stacked patch antenna fabricated using additive manufacturing techniques.

The proposed antenna consists of a slotted driven patch operating near 2.5 GHz with a second resonant mode near 5 GHz. A parasitic patch …

Speaking Back Through Stories: Storytelling And The Politics Of Resistance, Korka Sall

Wagadu: A Journal of Transnational Women's & Gender Studies

Black women have long served as storytellers, knowledge producers, and custodians of collective memory across Africa and its diaspora. Through oral traditions, literature, and film, they have created networks for the circulation of knowledge while fostering Pan-African consciousness, preserving cultural heritage, and educating communities about identity, justice, and self-determination. Their narratives challenge systems of colonialism, patriarchy, and historical erasure by centering Black women's voices and lived experiences within transnational conversations about history, culture, and belonging. This paper examines Aminata Sow Fall's Le Revenant (1976), Bessie Head's short story "Life" (1977), and Diabou Bessane's documentary Les Mamans de l'Indépendance …

Motherhood And The Illusion Of Delayed Gratification In Gerotti Kyomuhendo’S Waiting And Secrets No More, Mopelola R. Olayiwola

Wagadu: A Journal of Transnational Women's & Gender Studies

The birth of a girl child in most African societies automatically signals the arrival of another procreator. Her role is assigned long before birth: she is to be a woman, a wife, and a mother whose nurturance continues until death. Motherhood demands nurturing children alongside the husband, and most myths tie a woman’s relevance to this single role. To ensure undivided attention to this occupation, societies empower the virtue of patience. As a result, many African narratives corroborate the ideology of delayed gratification, encouraging women to give excessively toward a distant future when children may return the favour. Little attention …

From The Traditional Role Of Motherhood To The Creation Of Ritual Fertility Dolls Among The Ashanti People, Youssoupha Mane

Wagadu: A Journal of Transnational Women's & Gender Studies

This article explores the art and traditional sculpture of the Ashanti people of Ghana. The study delves into the symbolic, spiritual, therapeutic, and psychological implications of ritual fertility dolls known as Akua’ba, which serve as a means for infertile women to experience the joy and delight of motherhood. The study will also focus on how accessing motherhood is highly esteemed and regarded as a social obligation in most African cultures. The psychological burden and pressure associated with the social duty of bearing children to avoid ‘‘social death’’ or being ‘‘the dead end of human life’’ is undoubtedly at the root …

Reclaiming The Silenced: West African Women, Anticolonial Activism, And Storytelling As Historical Resistance, Tahsina Nasir

Wagadu: A Journal of Transnational Women's & Gender Studies

This paper examines the systematic erasure of West African women from dominant historical narratives of anticolonial liberation, focusing on decolonization and post-independence nation building in Ghana, Guinea-Bissau, and Nigeria. Although women played central roles in organizing, mobilizing, and educating during nationalist movements, their contributions were increasingly sidelined once state power was achieved. Drawing on feminist historiography, Black feminist thought, and archival and literary sources, this study analyzes how state actors dismantled autonomous women’s organizations, including the Federation of Ghana Women, and confined women to symbolic roles within party-controlled structures. Figures such as Hannah Kudjoe, once central to political mobilization, were …

Political Linguistics And Epistemic Agency: Universal Write Publications And The Defense Of Global Black Knowledge, Ayo Sekai

Wagadu: A Journal of Transnational Women's & Gender Studies

As linguistic erasure intensifies across the African world, the preservation of African-centered knowledge systems has become both a scholarly and political imperative. This article examines the relationship between linguistic imperialism, epistemic agency, and scholarly sovereignty through the intellectual trajectory of Dr. Ayo Sekai, political linguist and founder of Universal Write Publications (UWP), a Black woman–owned academic press dedicated to culturally grounded scholarship. Expanding traditional understandings of linguistic imperialism, Dr. Sekai advances political linguistics beyond structural language dominance to examine who holds linguistic power and how that power operates through dog whistle politics, signaling terms, and policy language code—discursive patterns embedded …

Spcc: Inferring Spatial Cell-Cell Interaction By Integrating Single-Cell And Spatial Transcriptomics, Tiangang Wang, Yu Zhou, Xi Liu, Sijia Wu, Liyu Huang, Kexin Huang, Xiaobo Zhou

Faculty, Staff and Student Publications

Study of single-cell spatial biology reveals the importance of integrating single-cell and spatial data for capturing spatial structure at individual cell resolution in various fields. With the lack of cellular-level information in most spatial data, it is necessary to integrate single-cell and spatial data. Here, we developed a deep learning computational framework for alignment and mapping of unpaired single-cell and the spatial data by using adversarial joint-variational autoencoder and Random Forest model (SPCC). SPCC will generate a mapping matrix for single-cell and spatial positions that can transfer spatial location to individual cells. SPCC can be used to perform downstream analysis, …

Improving Advanced Care Planning Conversations And Documentation Through App Education And Standardized Epic Workflow: A Quality Improvement Initiative, Michelle N. Rutter, Emily Goldstein

Doctor of Nursing Practice (DNP) Student Projects

Background & Significance: Advance care planning (ACP) is essential for ensuring (GOC), particularly in acute care settings, defined in this paper as inpatient hospital environments, including critical and intensive care units (ICU), where a patient’s decision-making capacity could become impaired. ICU patients are often critically ill and may lose the ability to make health care decisions. Family uncertainty regarding patient preferences frequently exacerbates psychological distress regarding GOC. Restricted access to ACP may result in non-concordant medical care, as well as elevated healthcare expenditures driven by the underutilization or inappropriate allocation of critical resources. Despite the recognized importance of ACP and …

Investigating The Links Between Iq, Emotion Dysregulation, And Respiratory Sinus Arrhythmia In Childhood Antisocial Behavior, Isley Jean-Pierre

Student Theses

This study examined relationships among cognitive ability, emotion dysregulation, physiological regulation, and antisocial behavior. Participants were 340 children ages 7-10. Caregivers reported on emotion regulation, aggression, and delinquency, and children completed cognitive assessments. Intellectual profiles were classified as even or uneven. No significant differences in aggression or delinquency were found between intellectual profiles. Emotion Regulation Checklist scores mediated relationships between VIQ and both aggression and delinquency. Resting RSA mediated the relationship between VIQ and delinquency, although the indirect effect was small, whereas RSA reactivity did not mediate either outcome. Overall, findings suggest that emotion regulation may be a more consistent …

African American Experiences Accessing Mental Health Services In Rural Communities, Danielle O. Keith-Alexandre

Walden Dissertations and Doctoral Studies

African American communities have exhibited greater vulnerability in psychological functioning and well-being, and usage of mental health services for evaluation and treatment are lower than for other groups, due to a range of barriers, including geographic location and lack of access. There is a lack of research on the difficulties African Americans face in accessing mental health services in U.S. rural communities. The purpose of this qualitative study was to explore, from a phenomenological approach, the lived experiences of African American adults residing in rural Pennsylvania mid-U.S. Eastern Coastal communities in regard to accessing mental health services. The social-ecological model …

Relationship Between Hospital Case Management Leadership Style And Employee Engagement, Malinda Ellis

Walden Dissertations and Doctoral Studies

Employee engagement among hospital-based nurse case managers is important because these nurses support discharge planning, utilization management, care coordination, and safe patient transitions. Although leadership style has been studied in nursing, limited research has examined its relationship to engagement among nurse case managers. The purpose of this quantitative, nonexperimental, correlational study, using House’s path-goal theory, was to examine the relationship between transformational, transactional, and laissez-faire leadership styles and employee engagement among hospital-based nurse case managers. Data were collected from 89 registered nurse case managers in acute care settings in the United States, who completed the Multifactor Leadership Questionnaire, Short Form, …

Social Workers’ Perceptions Of Pediatric Hiv Disclosure Process, Colleen Myrie

Walden Dissertations and Doctoral Studies

Although the social problem of pediatric HIV disclosure has been studied by researchers internationally, there remains a gap in the experiences of social workers in facilitating this process. The purpose of this generic qualitative study was to explore the experiences and perceptions of social workers in the United States regarding the disclosure process for HIV positive children. This study was grounded in Rosenstock’s health belief model, which posits that an individual will take necessary action to prevent or manage a disease based on their perceptions of health. This model was effective in helping to identify what social workers think about …

Summit Report: Nuclear Deterrence In An Uncertain World, Manolis Priniotakis

GNSI Summit Reports

The Global and National Security Institute’s Tampa Summit 6 took place on March 24-25, 2026, and examined a nuclear weapons environment marked by renewed uncertainty, weakened institutions, and rapid strategic change. General (Ret.) Frank McKenzie’s opening keynote framed the central challenge: The nuclear age never ended, but the United States and its allies spent much of the post-Cold War period looking away at other threats while Russia, China, North Korea, and others adapted. The world is now moving from the longstanding and relatively stable “two-body” nuclear order centered on the United States and Russia toward a far more complex “three-body” …
