The Role Of Individual Specialization In Migration Phenology And How Restored Habits Are Used By Native And Nonnative Fishes, Austin Garner

All Graduate Theses and Dissertations, Fall 2023 to Present

Native fish species around the world have declined due to habitat loss, habitat fragmentation, and the spread of non-native species. Because these problems often happen at the same time and interact, recovery efforts can stall unless they address all of the factors limiting a species' comeback. The June sucker (Chasmistes liorus), native only to Utah Lake, UT, has declined for many of these reasons, though its recovery effort has made significant progress due in large part to a successful hatchery program. Yet, the recovery efforts have not yet been able to establish a self-sustaining population in Utah Lake, …

'Fast' And 'Slow' Water Handling Strategies Explain Pinyon Pine Decline And Juniper Expansion, M. Faraz Rehman

All Graduate Theses and Dissertations, Fall 2023 to Present

Across the western United States, pinyon and juniper woodlands are changing with pinyon pine trees dying back while juniper becoming more abundant. Previous studies suggested that pinyon may lose more water during drier periods. But water loss is only part of the story. Water inputs, or how plants absorb water, are also likely to be important, but rarely well understood. To better understand this, we measured how pinyon and juniper absorb water from different soil depths and how actively they lose water through their leaves. Measurements were made over two years at three sites that ranged from more dry to …

Magnetic Properties And Ultrafast Spin Dynamics In Quantum Materials, Trung Kien Mac

All Graduate Theses and Dissertations, Fall 2023 to Present

Modern electronics mostly work by moving electric charge, which generates heat and hence wastes energy, especially as devices become smaller and faster. An alternative is to use the spin of electrons (a tiny magnetic property) and related “valley” states in certain atomically thin materials to store and process information more efficiently. This thesis explores how magnetism and spin behavior can be created and measured in a family of ultra-thin materials known as van der Waals quantum materials. Three kinds of materials are studied. First, atomically thin semiconductors are shaped into narrow nanoribbons. Because of their narrow size, their edges can …

The Evolution Of Hymenopteran Recombination Rates, Timothy John Delory

All Graduate Theses and Dissertations, Fall 2023 to Present

Individuals of some species mix their DNA frequently when producing sex cells, while others do so much less. Hymenopterans (ants bees and wasps) are especially useful for understanding this variation for several reasons. They show large differences in this frequency of shuffling, or rate of recombination, have well-studied genomes, and vary widely in how they live and reproduce. I capitalized on these features examines how recombination rates have evolved in this group at the trait, and gene level.

First, I revisited long-standing ideas about why recombination rates differ among these species, incorporating more than a decade of new research. This …

Flow And Professional Identity Through Lived Experiences Of Doctoral Students In An Online Immersive Instructional Framework, Leticia De Leon

Teaching and Learning Faculty Publications

This qualitative phenomenological study explored the lived experiences of doctoral students engaged in an immersive instructional framework within an online course on Adult Learning Strategies. The purpose was to examine how immersive design elements (De Leon, 2020) and flow theory as defined through Csikszentmihalyi’s (1990) and Shin’s (2006) helped participant engagement via enjoyment, telepresence, focused attention, and time distortion. Participants completed five narrative journals across two immersive modules designed with multimodal, authentic, interactive, and autonomous elements. Data analysis followed Moustakas’ (1994) phenomenological reduction, including bracketing, horizontalizing, thematic clustering, and a synthesized essence of experience. Results revealed that students experienced flow …

Yap1-Dependent Regulation Of Cell Size In Bcam-Positive Limbal Corneal Progenitor Cells, Kosei Suzuki, Shinri Sato, Markus H. Frank, Natasha Y. Frank, Yuzuru Sasamoto

Research outputs 2022 to 2026

Cell size has been associated with stem and progenitor cell states across multiple tissues, yet its regulation in the human corneal epithelium remains incompletely understood. This study aimed to characterize cell-size differences among limbal and corneal epithelial cell populations defined by the limbal stem cell (LSC) marker ABCB5 and the transit-amplifying cell (TAC) marker BCAM, and to investigate the molecular regulators of progenitor cell size. ABCB5-positive LSCs and BCAM-positive TACs were identified and isolated by flow cytometry, and the mean cell size was estimated using forward scatter (FSC). As a result, ABCB5-positive LSCs were significantly smaller than ABCB5-negative limbal epithelial …

It draws on the results of a large-scale Scoping Study that sought perspectives from experts equally distributed across (1) industries providing …

Casual Killing In The Home: Ecological Citizenship And The Micro-Geopolitics Of Mosquito Cohabitation, Orlando Woods, Junxi Qian

Research Collection College of Integrative Studies

This article explores how the visceral acts of being bitten by and killing mosquitoes can underpin the formation of ecological citizenship. This form of citizenship is premised on human-nature entanglement and raises questions concerning how the rights and responsibilities stemming from such entanglement become distributed across the public and private domains. As a space in which mosquito cohabitation is contested daily, the home is a key site through which ecological citizenship can be forged and theoretical debates concerning urban political ecology can be extended. Human-mosquito entanglements in the home can reveal the limits of public pest management strategies, the partiality …

Misplay Or Malice? Players’ Interpretations Of Poor Gameplay In Competitive Team-Based Multiplayer Online Games, Valerie Yu, Benjamin H. Detenber, Sonny Rosenthal

Research Collection College of Integrative Studies

Research on perceptions of gaming toxicity has focused on its verbal forms, while gameplay-related forms remain relatively understudied. Furthermore, assessments of gameplay actions as toxic may depend on situational considerations. The present study used a controlled experiment to examine player interpretations of gameplay sabotage using pre-recorded gameplay scenarios from the game, League of Legends. We found that the presence of gameplay sabotage elicited stronger negative emotions and triggered greater player-reported intentions to retaliate and correct the offending player than in comparable instances of unintentional poor gameplay. Further exploratory analyses suggested that participants rated poor gameplay as less acceptable in more …

Ephemeral To Empowered? International Comparison Of Women’S Participation In Web Series Production, 2012–2019, Nicola Evans, Marion Mccutcheon, Emilia King, Joel Bassaget, Steinar Ellingsen

Research outputs 2022 to 2026

Women are significantly underrepresented in above-the-line roles in film and television, but anecdotal evidence suggests they are gravitating to web series. To explore this, the authors built the largest known international archive of web series released during 2012–2019 and analysed women’s participation. In the top five web series producing countries in the West, women achieved or approached parity with men in producing, directing and writing, but not cinematography. Do achievements in low-budget, transitory media count for anything? Drawing on ephemeral media scholarship, we discuss the potential of such forms to disturb entrenched patterns of gender discrimination in screen industries worldwide.

Safety And Effectiveness Of Behavioural Activation For Chronic Pain: A Protocol For A Systematic Review And Meta-Analysis Of Randomised Controlled Trials, Fangyuan Zheng, Laura Hynes, Richard J. Gray, Irene Ngune, Jacqueline Sin, Martin Jones

Research outputs 2022 to 2026

Background/Objectives: Chronic pain is a prevalent and complex condition associated with substantial physical, psychological, and social burden. Behavioural activation (BA), a structured psychological intervention originally developed for depression, may be relevant to chronic pain through its focus on reducing behavioural avoidance and increasing engagement in meaningful activities. Although BA has been applied in studies involving people with chronic pain, the safety and effectiveness of BA in this population have not been comprehensively synthesised. This systematic review and meta-analysis will examine the safety and effectiveness of BA for people with chronic pain.

From Open Banking To Banking-As-A-Service: Regulatory Challenges In The Evolution Of Financial Intermediation, Nydia Remolina Leon

Research Collection Yong Pung How School Of Law

Over the past decade, financial innovation has moved from open banking, centred on consumer-permissioned data sharing, to banking-as-a-service (BaaS), which modularises core banking functions through application programming interfaces. This shift allows fintechs and non-financial platforms to embed financial products seamlessly, reducing transaction costs and fostering innovation. Yet the 2024 collapse of Synapse in the United States exposed the fragility of this model when intermediaries operate outside robust oversight, leaving consumers without recourse and revealing liability fragmentation and regulatory blind spots. This paper distinguishes BaaS from open banking, open finance, and embedded finance, and maps leading global models – from bank-led …

Not A Pretty Picture: Race, Gender, And Inequality In The Legal Profession And Legal Education, Tanina Rostain

Georgetown Law Faculty Publications and Other Works

Responding to renewed interest in law school as a path to a career “to do well and do good,” this essay examines Nelson, Dinovitzer, Garth, Sterling, Wilkins, Dawe, and Michelson’s The Making of Lawyers’ Careers and its account of inequality and opportunity in the American legal profession. Based on a 20-year study of more than 2,000 lawyers, the book traces how credentials, race, gender, class, and law school selectivity profoundly shape career trajectories. The essay situates those findings within the divide in private practice between corporate practice and people law and interrogates the professional ideology—rooted in the lawyer’s traditional role …

Are We Winning At Twinning? Persistent Cni Use In Identical Kidney Transplants., Nicholas S. Herrera, Shivani Wadnerkar, Diane M. Cibrik

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Calcineurin inhibitors (CNIs) revolutionized kidney transplantation by reducing acute rejection rates. Identical twin kidney transplantation is the only setting in which the allograft is immunologically indistinguishable from self, yet CNI use persists. We characterized CNI utilization across end-stage kidney disease etiologies and examined whether CNI exposure was associated with reduced rejection or improved death-censored graft survival (DCGS).

METHODS: We performed a retrospective cohort study using scientific registry of transplant recipients data (January 2000-August 2025). Among 255 adult identical twin kidney transplant recipients, discharge regimens were categorized by CNI use; Firth penalized Cox regression was the primary method for 10-year …
