Newborn Spinal Needle, Allison Inouye, Kyle Morton, Evan Russell

Biomedical Engineering

Spinal punctures, or lumbar punctures, are important diagnostic procedures used to collect cerebrospinal fluid (CSF) to diagnose issues in the central nervous system (CNS) such as meningitis. While these procedures are routinely performed on adult and neonatal patients, the current tools are not optimized for use on newborns. Existing spinal needles are often modified versions of adult devices, leading to challenges in fluid collection efficiency, user ergonomics, and patient safety when used in neonatal care.

The Newborn Spinal Needle Project aims to design and develop a spinal needle specifically optimized for neonatal anatomy and clinical workflow. The goal is to …

An Intersectional Framework For Effectively Mentoring Latinas In Stem Fields, Rosalynn A. Vega

Anthropology Faculty Publications

While Latinas are underrepresented across all areas of academia, this problem is especially severe in the science, technology, engineering, and mathematics (STEM) fields. This chapter offers a “best practices,” step‑by-step guide for how to effectively mentor Latinas in STEM fields—drawing from interdisciplinary concepts, culled from critical race studies, statistics, and anthropology—and personal experience as a Latina in STEM, mentor, and mentee. Crenshaw’s (1989) theory of intersectionality, Farmer’s (1999) notion of structural violence, and multivariate statistical modeling is used to demonstrate that intersectional inequality can be traced back to social structures. Multi‑gender and multiethnic mentoring by individuals who are motivated to …

The Space Between Seams, Rachel M. Clarke

School of Art, Art History, and Design: Theses and Student Creative Work

Through the use of form, softly muted colors, and play with transparent materials, I create ethereal drawings and immersive installation experiences. I work with the softness in fabric and the controlled detail in drawing. In doing so, I am enveloping myself in the drive to create, pushing the viewer to be spatially aware of their bodies existing in space.

This body of work exists as I am processing the state of my own body. We engage and perceive the world through our bodies. The fabric panels I create call to the porosity and permeability of human skin. The skin contains …

Promoting Maternal Health Through Community-Based Education: A Quality Improvement Initiative On Hypertension And Pregnancy Complications In An Outpatient Setting, Areli Mendez

Doctor of Nursing Practice Projects

Background

Hypertensive disorders during pregnancy remain one of the leading causes of maternal and fetal complications worldwide, particularly among underserved and minority populations. Spanish-speaking women often experience barriers related to language, limited health literacy, and reduced access to culturally appropriate education, which may delay the recognition of warning signs associated with pregnancy complications. Early education and awareness are essential to improve maternal outcomes and promote timely medical intervention.

Purpose Statement

The purpose of this Doctor of Nursing Practice (DNP) project was to evaluate the effectiveness of a culturally tailored educational intervention designed to improve maternal knowledge regarding hypertension during pregnancy …

Interest Fit Beyond The Riasec: The Comprehensive Assessment Of Basic Interests-O*Net (Cabin-Net), Chu Chu, Kevin A. Hoff, Zihan Liu, Nicholas F. Heimpel, Anthony Greco, Frederick L. Oswald, James Rounds

Research Collection Lee Kong Chian School Of Business

Over the past half-century, Holland’s RIASEC model has dominated vocational interest research. Although the RIASEC categories effectively capture general occupational themes, their breadth obscures meaningful variability across underlying basic interests, which are more refined interest scales. In this research, we adapted the Comprehensive Assessment of Basic Interests (CABIN; Su et ., 2019) to be used alongside O*NET for assessing interest fit, resulting in the 60-item CABIN-NET that measures 20 basic interest scales organized under RIASEC domains. In Study 1, we refined items for the CABIN-NET using a nationally representative adult sample (N = 768). In Studies 2 and 3, we …

Global Value Chains And Economic Inequality, Vivek Soundararajan, Ari Van Assche, Hari Bapuji, Gokhan Ertug

Research Collection Lee Kong Chian School Of Business

In their inaugural editorial, Van Assche and De Marchi (2024) argued that meaningful progress in international business policy requires a more fine-grained understanding of how private international business practices intersect with public policy objectives. This editorial builds on that insight by applying it to a critical yet still underexplored issue – one on which we hope to see more research in this journal: the role of multinational enterprises (MNEs) and global value chains (GVCs) in shaping economic inequality within developing economies. Decisions related to sourcing, contracting, and GVC governance are inherently distributional rather than neutral, with important implications for how …

Collaborative Work Management Technologies And Managerial Intensity In U.S. Corporations: An Examination, Piyush Gulati, Arianna Marchetti, Phanish Puranam

Research Collection Lee Kong Chian School Of Business

Do digital technologies reinforce managerial hierarchies or, instead, make them less relevant? We propose that the answer to this question depends on the nature of the technology: specifically, its relative impact on managers' capacity to supervise and on subordinates' need for supervision. Applying this framework to collaborative work management (CWM) technologies that facilitate real-time collaboration, communication, and task coordination, we predict that the adoption of such technologies should reduce managerial intensity and increase decentralization in organizations. To test this prediction, we use a difference-in-differences design on a novel data set built from over 26 million job listings (Lightcast) and over …

A Haplotype Reference Panel And Genotype Imputation Framework For The Black Soldier Fly (Hermetia Illucens), Peter Muchina, Johnson Kinyua, Fathiya Khamis, Chrysantus M. Tanga, Maria Altaf Satti, Grum Gebreyesus, Goutam Sahana, Zexi Cai

All Peer-Reviewed Publications

Low-coverage whole genome sequencing (lcWGS) combined with genotype imputation provides a cost-efficient alternative to high-coverage sequencing for large-scale genotyping. Although widely implemented in human and livestock genomics, this strategy has not yet been systematically optimized for insects of industrial importance. The black soldier fly (BSF, Hermetia illucens ) is increasingly used in global waste bioconversion and sustainable protein production, but genomic resources remain limited. Here, we develop the first BSF haplotype reference panel, containing ∼29.8 million high-quality SNPs from 168 high-coverage genomes, and benchmark imputation performance using a validation experiment in which 33 high-coverage individuals were down-sampled to low coverage …

Fgl2-Knockout Tumor Cells Serve As A Vaccine Inducing Long-Duration Brain-Resident Memory T Cells That Reject Subsequent Intracranial Tumor Cell Challenges, Sheng Zhang, Yining Jin, Zhiliang Jia, Xueqing Xia, Yang Li, Qi Wang, Jing Wang, Jian Wang, Joya Chandra, Gregory K Friedman, Shulin Li

Faculty, Staff and Student Publications

The failure to prevent brain tumors, including both recurrent primary and metastatic brain tumors, is the primary cause of patients' mortality. We developed a novel whole tumor-cell vaccine to rapidly induce long-duration brain-resident memory T (TRM) cells that prevent brain tumor progression. Ten Fgl2-KO primary and metastatic tumor cell lines, generated via CRISPR/Cas9, were used to vaccinate mice and for intracranial challenges with the WT tumor cells. Not only did vaccinated mice reject these tumor cell challenges, but also more than half of these mice became long-duration survivors. Transplanting brain immune cells from vaccinated mice into naïve mice enabled this …

Mri Analysis Of The Wrist: Does The Presence Of Palmaris Longus Affect Median Nerve Position?, Victor B Chavez, Dean W Smith

Faculty, Staff and Student Publications

Background: Understanding the median nerve's position relative to surrounding anatomy is essential; however, there are many variations among individuals. This study assesses differences in median nerve position with or without palmaris longus (PL). We hypothesize that PL presence alters median nerve position, resulting in a greater distance to the skin volar surface, a decreased distance to the radius volar surface, and an increased distance to the flexor carpi radialis (FCR).

Methods: 1193 wrist magnetic resonance imaging (MRI) studies were retrospectively reviewed from 2019 to 2023. One hundred adults ages 18 to 50 meeting criteria were included for a power > 80%: …

Generalizability Analyses With A Partially Nested Trial Design: The Necrotizing Enterocolitis Surgery Trial, Sarah E Robertson, Matthew A Rysavy, Martin L Blakely, Jon A Steingrimsson, Issa J Dahabreh

Faculty, Staff and Student Publications

We discuss generalizability analyses under a partially nested trial design, where part of the trial is nested within a cohort of trial-eligible individuals, while the rest of the trial is not nested. This design arises, for example, when only some centers participating in a trial are able to collect data on non-randomized individuals, or when data on non-randomized individuals cannot be collected for the full duration of the trial. Our work is motivated by the Necrotizing Enterocolitis Surgery Trial (NEST), which compared initial laparotomy versus peritoneal drain for infants with necrotizing enterocolitis or spontaneous intestinal perforation. During the first phase …

Faculty, Staff and Student Publications

Breast surgery for aesthetic purposes, such as breast augmentation or breast reduction, and breast reconstruction after cancer treatment require an accurate structural (anatomical) and mechanical (functional) understanding of the breast components, including the fascial-ligamentous support system of the breast, to achieve optimal results. This paper aims to provide a comprehensive description of the mechanical behavior of the ligamentous and fascial connective tissues of the human female breast. Fasciae and ligaments obtained from 17 patients between 35 and 85 years of age who were undergoing mastectomy and three female cadavers were tested. Uniaxial tensile tests were conducted, and three constitutive models …

Faculty, Staff and Student Publications

Background: Segmental tracheal resection is rarely needed for advanced thyroid cancer but is among the most complex, high-risk thyroid surgeries.

Methods: Retrospective study of patients undergoing segmental tracheal resection for thyroid cancer at MD Anderson Cancer Center (2005-2024).

Results: We identified 120 patients with a median follow-up of 4.6 years (range 0.02-16.38). Papillary thyroid cancer was most common (68%). The median number of tracheal rings resected was 4 (range 1-9). Seventeen (14%) patients had a new tracheostomy placed at the time of surgery, with 11 (9%) remaining trach-dependent at last follow-up. Twenty-six (22%) patients had a return to the operating …

Exploring The Personal Management Interview Program As A Burnout Prevention Strategy In Policing: A Qualitative Case Study, Lance C. Arnold

Electronic Theses and Dissertations

Police officers in the United States experience severe burnout at rates exceeding other service professions, with approximately 75% experiencing burnout symptoms. Current interventions predominantly focus on individual coping mechanisms rather than addressing organizational and leadership factors contributing to burnout. This qualitative single-case study explored the perceptions and experiences of police leaders and officers concerning the utility of a personal management interview program to foster positive leadership behaviors as a resource-oriented preventive strategy against burnout in a midsize municipal police department in Texas. The study employed semistructured virtual interviews with eight participants: four police leaders and four police officers who had …

A Narrative Study On The Resilience Of Women In Technology Careers, Gina J. Baldridge

Electronic Theses and Dissertations

In spite of the promotion of science, technology, engineering, and mathematics (STEM) education and careers, there is a lack of women entering the STEM workforce and majoring in STEM subjects. Women can experience gender bias and workplace marginalization in STEM careers, but have learned coping strategies that have contributed to their technology career resilience. The purpose of this narrative qualitative study was to explore how women working as individual performers and leaders in technology companies told their career stories of resilience through the perspective of change acceptance, confidence, and communication, three factors in Kumar’s CR8 model of resilience. The model …

Online Age Gating: An Interdisciplinary Evaluation, Noah Apthorpe, Brett Frischmann, Yan Shvartzshnaider

Faculty Publications

The recent surge in regulation seeking to establish age-based governance online is part of a decades-long attempt to establish online zoning. It is driven by active development of technologies to estimate or verify user age based on various characteristics of users, their credentials, or their activities. However, these developments have heightened prevailing concerns that online age gating technology will inevitably be abused and misused to cause a variety of privacy harms and rights infringements. This paper examines this ongoing debate by bridging technical and legal scholarship to explore the current state of online age-based governance. We discuss the current legal …

High-Frequency Functional Trajectories Predict Depressive Worsening In Singapore's Community-Dwelling Older Adults, Kaung Htet Tun Salai, Yi Wen Tan, Grace Cheong, Paulin T. Straughan

ROSA Journal Articles and Publications

Background/Objectives: Functional difficulty and depression often coexist in older adults, yet local Singapore-based research often lacks detailed temporal resolution due to heterogeneity in ageing. This study employs non-parametric, data-driven longitudinal clustering to analyse functional trajectories and their association with depression, using high-frequency data to pinpoint key intervention periods. Methods: Data were drawn from 4273 community-dwelling older adults from Singapore Life Panel^® (2020–2024). Participants completed quarterly self-reported assessments of ADL, IADL and depressive symptoms (8-item CES-D). We employed k-means longitudinal clustering (kml) to identify functional trajectory groups and Cox regression to evaluate the hazard of increased depression (≥5-point increase in …

Association Of Human Papillomavirus On Risk Of Hiv Acquisition In African Women: Analyses From Mtn-020/Aspire, Christine L. Hathaway, Elizabeth R. Brown, Stephen Cherne, Alyssa L. Sepulveda, Zvavahera M. Chirenje, Nitesha Jeenarain, Logashvari Naidoo, Samantha Siva, Nishanta Singh, Kubashni Woeber

School of Medicine Publications

Background: Observational data on the synergy between human papillomavirus (HPV) infection and risk for HIV acquisition are needed. HPV clearance, associated with an influx of cells targeted by HIV, may increase HIV risk. This study examined the association between HPV and HIV acquisition using endocervical swabs collected in MTN-020/ASPIRE.

Methods: Healthy, sexually active women without HIV participating in the ASPIRE dapivirine ring study in Malawi, South Africa, Uganda, and Zimbabwe provided endocervical swabs monthly, which were tested for HPV-DNA. HPV status was classified into prevalent, persistent (HPV+ for at least 4 months), HPV clearance (HPV+ followed by HPV-), HPV acquisition …

Considering Barriers To Funding Fiscal Sponsorship: Insights From Sponsor And Project Leaders, Elliot M. Zettas, Todd L. Ely, Fredrik O. Andersson

The Foundation Review

This study explores barriers to funding fiscal sponsorship based on interviews with 68 leaders of sponsors and sponsored projects. Findings reveal that funders’ limited understanding and restrictive policies contribute to negative sentiment and reduced grant access for sponsored initiatives.

Despite fiscal sponsorship’s administrative efficiencies and mission-focused benefits, funders often perceive sponsored projects as less legitimate, misunderstand sponsor roles, and resist covering sponsor cost allocations when framed as fees. Structural complexities — such as shared EINs and geographic mismatches — further impede eligibility for funding.

This article concludes with actionable recommendations for funders and sponsors, including staff education, updated grant guidelines, …

Beyond Need: Exploring Readiness To Implement Change As A Predictor Of Nonprofit Capacity-Building Success, Bridget Y. Samuel

The Foundation Review

This mixed-methods exploratory study investigates whether organizational readiness to implement change predicts capacity-building success more reliably than the level of perceived need.

Using a six-factor readiness assessment measuring clear priorities, change management resources, time investment commitment, board engagement, systems infrastructure, and cash flow, data from 10 participating organizations reveal a significant correlation between readiness scores and early capacity-building outcomes.

The findings challenge three common field assumptions: that the greatest capacity-building need should drive selection, that capacity-building works uniformly across developmental stages, and that dysfunction can be addressed through “standard” capacity-building programming.

The Future Of Purpose-Driven Work: Evaluating A Case Study Of The Hybrid: Flexible Purpose Model At The Robert Wood Johnson Foundation, Jeff Williams, Melyssa Tsai O'Brien, Trish Abalo

The Foundation Review

This 15-month case study employed a comprehensive mixed-methods evaluation to document and assess the model across six key areas. Findings revealed the Hybrid: Flexible Purpose model preserved or improved grantmaking outcomes, enhanced staff well-being and autonomy, and expanded the diversity of the talent pool.

Challenges emerged regarding sustaining the organizational culture, fostering cross-team and informal relationships, and ensuring consistent policy implementation across teams, particularly in finding the optimal balance between stated goals and actual experiences during mandatory in-person gatherings.

Findings also documented a “hybrid coordination tax,” i.e., additional effort required to manage mixed in-person and virtual meetings and schedules.

Using Ai To Redirect Donor Support To Smaller Organizations, Madeleine Alegria, Brandolon Barnett

The Foundation Review

Despite rising interest in supporting local causes, many donors continue to give to large, nationally recognized nonprofits. This reflects ongoing structural barriers such as limited nonprofit visibility, decision fatigue, and search environments that prioritize brand familiarity.

At the same time, small-dollar giving has declined for three consecutive years, highlighting the need for more transparent, accessible, and trustworthy tools to support donor decision-making (Childress, 2024; Lilly Family School of Philanthropy, 2023).

In a 2024 evaluation study, 291 U.S. donors were randomly assigned to use either the Giving Compass Guide to Good platform or general internet tools to select a new nonprofit …

Moving Beyond Words To Action: A Practitioner’S Playbook For Achieving Collaboration Success, Tessa Lesage, Jonathan L. Romine, Jane Wei Skillern

The Foundation Review

This article argues that foundations must shift from acting as grantmakers alone to becoming active stewards of cross-sector collaborative networks.

Drawing from more than two decades of field experience and research each, the authors outline a framework for moving from collaborative rhetoric to action, identifying four essential and interconnected actions: fueling trust, elevating purpose, nurturing networks, and strengthening stewardship.

Through case examples, the article illustrates how authentic, trust-based relationships, shared goals, and relational network leadership can drive scalable, sustainable impact.

The article offers both a compelling critique of traditional philanthropic approaches and a strategic road map for how foundations can …
