Ai-Assisted Wheat Spike And Spikelet Detection And Density Mapping Using Multiscale Remote Sensing Data To Support Wheat Grain Yield Forecasting, Hillson Ghimire

Electronic Theses and Dissertations

Wheat grain yield is determined by the number of spikes per unit area, the number of grains per spike, and kernel weight. However, spike number and spikelets per spike are still measured predominantly through manual counting, a labor-intensive and subjective process that limits phenotyping throughput and selection intensity in modern wheat breeding programs. This thesis develops and evaluates a deep learning framework for automated, high-throughput phenotyping of wheat spike and spikelet traits across complementary imaging scales and implements the framework as a deployable platform. First, two large-scale benchmark datasets with oriented bounding box (OBB) annotations were established, comprising 48,521 spike …

The emergence and rapid adoption of digital health technologies (DHT) present unprecedented opportunities to democratize and reduce disparities in health care by monitoring health and disease at the point of care in all patients. However, limited access to DHT is becoming a major obstacle to realizing these goals. Access to DHT is influenced not only by well-recognized social determinants of health, but also by digital determinants of health, such as digital literacy and the need for broad access to digital infrastructure, as well as commercial and economic factors. Addressing these challenges and designing unbiased systems of care are essential to …

Study Of Fire Regimes In Southwestern Australia Using Geospatial Techniques, Ana Do Carmo Carvalho

Theses: Doctorates and Masters

The Northern Jarrah Forest in Southwestern Australia (SWA), part of a global biodiversity hotspot, is home to fire-sensitive tree species such as marri (Corymbia calophylla) and jarrah (Eucalyptus marginata). As climate change intensifies drought and extreme fire events, understanding the drivers of fire severity is increasingly critical. This thesis analyses fire regimes within the Mundaring drinking water catchment to better understand the spatiotemporal complexity of fire severity in relation to fire history and environmental factors.

The thesis commences with a review of three Fire History Databases (FHDs) used in SWA, highlighting significant inconsistencies and data gaps across time and space. …

Understanding Climate Change And Wellbeing Through Bhutan's Pursuit Of Gross National Happiness, Tashi Dorji

Theses: Doctorates and Masters

Climate change has evolved into one of the biggest global challenges of the twenty first century reshaping ecological systems and social conditions with wide-ranging implications for human wellbeing. Bhutan offers a distinct context to explore interactions between climate change and wellbeing as it remains guided by its wellbeing-centred development philosophy of Gross National Happiness (GNH). At the same time, it remains highly vulnerable to climate change despite being the only carbon negative country in the world. Nonetheless, the intersections between climate change and GNH have not been systematically explored.

This research aims to explore the relationship between climate change and …

Play-Based Learning In Private International Preschools In Cairo: Teachers' Perspectives, Kesha L. Stovall

Theses and Dissertations

This thesis explores how play-based learning is practiced and contextualized in private, international preschools in Cairo, Egypt through the perspective of teachers. It calls upon both historical and contemporary theories of play and play pedagogies ranging from the times of Plato and Al-Farabi to the 21st century with Montessori and Dewey. Using a contemporary theory of play presented by Stuart Lester and Wendy Russell as a guiding framework, it examines how play and play-based learning are implemented, shaped and even challenged in a Cairene context. These contexts include sociocultural factors such as parents’ expectations and aspirations, institutional barriers, teacher development …

Centring The Audience: Attitudes And Behaviours In Australian Arts Organisations, Katya Johanson, Abbie Trott, Mark Taylor, Anne Kershaw, Hilary Glow, Tracy Margieson

Research outputs 2022 to 2026

Many arts organisations seek to increase the diversity of their audiences. Recent literature suggests that this requires organisations to interrogate and change their ways of operating. This is a fundamental shift for a sector that has long considered the goal of diversifying audiences as a problem external to the organisation. Responding to this discrepancy, this article compares attitudes and behaviours among workers in arts organisations, to identify whether staff see the need to make change and practise the behaviours required. It identifies and uses three organisational capabilities–‘dynamic capabilities’, ‘social networks’ and ‘business improvement processes’–to frame an analysis of a national …

Half-Armenian, Fully Diasporic: Navigating Memory, Trauma, And Identity In Marcella Polain’S The Edge Of The World, Sebnem Nazli Karali

Research outputs 2022 to 2026

This work of creative nonfiction employs a hybrid creative-critical methodology that combines autobiographical narrative and interview-based research within the framework of memory studies. Drawing on Marianne Hirsch’s concept of postmemory, the article examines how knowledge of the Armenian Catastrophe is transmitted, refracted, and contested across generations in the Armenian diaspora in Australia. It situates The Edge of the World, Marcella Polain’s semi-autobiographical novel, within broader traditions of diasporic and postmemory writing, arguing for its significance as a literary meditation on historical rupture and inherited trauma. Interweaving Karali’s personal diasporic narrative with a close reading of Polain’s novel and her in-depth …

Holistic Stormwater Management In The Bound Brook River Basin, New Jersey, Sana Mirza

Theses, Dissertations and Culminating Projects

This dissertation presents a holistic framework for stormwater management in the Bound Brook River Basin, an urban watershed in central New Jersey that faces chronic nutrient enrichment and climate-driven hydrologic changes. The research integrates water-quality trend analysis, hydrologic modeling, and low-impact development (LID) optimization to assess current and projected watershed responses. By combining empirical monitoring data with downscaled climate simulations and spatial prioritization, the study utilizes a holistic approach for stormwater management planning. The first objective was to characterize nutrient dynamics and hydrologic transport pathways for nitrogen, phosphorus, and total suspended solids (TSS) from 2004 to 2019. Using bi-monthly monitoring …

Lack Of Disparities In Postoperative Care After Ileocecal Resection In Patients With Crohn's Disease At Tertiary Inflammatory Bowel Diseases Centers, Shannon Coombs, Molly Powell, Kemmian Johnson, Jessica Hu, Mollie Webb, Philip Mcdaniel, Parakkal Deepak, Edward L Barnes

2020-Current year OA Pubs

BACKGROUND: Prior studies suggest that longer drive time (DT) to specialists and higher area deprivation index (ADI) are linked to worse outcomes in inflammatory bowel disease (IBD), but their impact on postileocolic resection (ICR) care in patients with Crohn's disease (CD) is not well defined.

OBJECTIVES: We aimed to evaluate disparities in post-ICR care based on DT and ADI.

METHODS: Spatial analysis was performed with ArcGIS Pro to geocode patient and medical facility addresses with StreetMap Premium locators. High DT was defined as >60 min from the center. Data were analyzed using basic statistics and multivariate logistic regression.

Regulatory Design Choices For Ai: The What, The Who And The How, Aziz Z. Huq

Public Law and Legal Theory Working Papers

This chapter identifies three common design choices that must be made in the course of an effort to regulate artificial intelligence “AI”). By isolating the way in which those different sovereign regulators approach these choices in respect to AI, it is possible to evaluate more clearly the likely effects of regulation, and to better understand aspects of regulatory design that to date have been overlooked. First, the “what” of AI regulation is not just a matter of how “AI” is defined, but also which element of the technology stack is targeted by law: compute, data, or models. Second, the “who” …

Overcoming The Literacy Gap In K-5 Students From A District Perspective: A Qualitative Study, Sarah G. Boles

Doctor of Education Dissertations

The purpose of this qualitative study was to explore how district leaders respond to literacy gaps among kindergarten through fifth-grade students in a small, rural school district in Northwestern North Carolina. While previous research has focused specifically on classroom practices, less is known about the role of district leadership in shaping system-level approaches to literacy improvement. Using a qualitative research design, data were collected through semi-structured interviews with 18 participants, which included nine elementary lead classroom teachers and nine elementary school leaders (five principals, two assistant principals, and two instructional coaches). The culminating focus group included six teachers, three principals, …

Improved Climate Services In Hawai‘I: The Collaborative Development Of Drought-Related Decision Support Tools, Ryan J. Longman, Derek Ford, Cherryle Heu, Jennifer Geis, Abby Frazier, Christian P. Giardina, James T. Potemra, Sean B. Cleveland, John J. Marra

Geography

Rising temperatures, prolonged droughts, and increasingly variable rainfall are negatively impacting natural and cultural resources and agricultural production systems in Hawai‘i. To effectively manage resources in the face of these changes, stewards and producers now require accurate, timely, and site-specific climate data and information. However, access to such data as well as the ability to interpret available data remain limited for many sectors. In response to various needs, a team of scientists working with the Pacific Drought Knowledge Exchange (PDKE) has developed two open-source decision-support tools (DSTs) through a collaborative, user-informed process aimed at closing longstanding gaps in local climate …

Elephant Economics And Agrarian Transitions: Conditions For Benefiting From Elephant Tourism Market In An Upland Karen (Paganyaw) Village, Xiaoyun Neo, Aswin Baharuddin, Nur Fadilah Sunardi

Forest and Society

In rural, upland northern Thailand, Indigenous Karen (Paganyaw) communities have long practiced diversified subsistence cultivation and forest-based livelihoods. Yet state conservation policies and tourism-led development are reshaping these agrarian systems and livelihoods. This paper explores how one Karen (Paganyaw) community in Chiang Mai province reconfigures its livelihood strategies amid the decline of swidden cultivation and the rise of elephant tourism as a new rural economy. Beyond subsistence cultivation, villagers are seeking to diversify their households and personal income by participating in this new economic sector. We argue that the transition out of small-scale agriculture into tourism is not a neutral …

The Unequal Partnership Behind Biodiversity Conservation Efforts In The Eastern Democratic Republic Of Congo, Alexandra Rasoamanana, Eliezer Majambu, Dominique Bikaba, Symphorien Ongolo, Emilie Dupuits

Forest and Society

The growing demand for inclusivity in conservation has led international conservation organisations (ICOs) to collaborate more with local conservation organisations (LCOs). This paper assesses such partnerships through a community-led initiative establishing a wildlife corridor between Maiko and Kahuzi-Biega National Parks. In this region, resource conflicts are often cited as a political justification for recurring conservation failures. However, this framing overlooks crucial questions about how fairness and sustainability in conservation are constructed in practice, particularly within contested forestlands where multiple groups claim legitimacy over ownership. We analyse the structural conditions that enable or constrain the formation of authentic partnerships. Such partnerships …

Small-World Simulations: A New Method To Test The Effect Of Legal Rules, Johannes Kruse

Coase-Sandor Institute for Law & Economics Research Paper Series

Small-world simulation exposes an artificial society to a legal rule and observes what its members do. The agents are driven by language models: their conduct is not stipulated in equations but reasoned in their own words. The architecture can be turned on any legal regime; personalized speed limits are the demonstration, chosen because rational-choice and behavioral predictions there conflict. Validated against documented driving patterns, the simulation generates behavior no one wrote into it. Because language models are trained on what people say rather than do, the method estimates orderings, not levels: a benchmark, not a substitute for evidence.

Utilizing Emergency Management Audio Messages For Traffic Incident Management Performance Measures, Christopher Gartner, Vihaan Vajpayee, Jairaj Desai, Darcy M. Bullock

JTRP Technical Reports

Timely and accurate information regarding roadway incidents is critical for Traffic Management Centers (TMCs) to maintain safety and mobility. While Intelligent Transportation Systems (ITS) cameras and crowdsourced data provide significant visibility, rural interstate corridors often suffer from coverage gaps, or "blind spots," where incidents go undetected until significant queuing occurs. Public safety radio communications serve as the primary coordination method for first responders, creating a "verbal infrastructure" that contains vital information regarding incident location and severity. This study evaluates the feasibility of using Automatic Speech Recognition (ASR) to bridge these gaps by monitoring and analyzing radio traffic. The project developed …

Law And The Moral Geography Of Urban Education, Rebecca Horwitz-Willis

Lewis & Clark Law Review

In contemporary discussions, urban schools are often labeled as “bad,” while suburban schools are generally regarded as “good.” These assessments are typically based on achievement metrics, resource allocations, and the demographics of student populations. However, this Article offers a new lens through which to analyze the valuation of urban schools: the relationship between local vice regulation and what I term “educational geographies” in urban areas. Specifically, it argues that the location of vice institutions in cities has disproportionately impacted Black neighborhoods, thereby devaluing the educational geographies within these communities. These distributions do not just impact market value, but rather, also …

Gender-Inclusive Language In Spanish: A Data-Informed Sociolinguistic Exploration Of Naming Variation, Silvia Rivera Alfaro, Jonathan Hanon

Publications and Research

ABSTRACT

This paper presents a data-informed sociolinguistic exploration of the variation in the names given to gender-inclusive language in Spanish. We use publicly available Google Trends (GT) data to describe the frequency of usage of different names over time and explore their geographical distribution. To account for the challenges and limitations of using Google Trends, we compare the data with information from two large linguistic corpora (CORPES XXI and Google Books Ngram Viewer). Using these tools, we generate small datasets to explore the intricacies of the topic addressed in this paper. In our literature review, we identified 17 names for …

Reclaiming The Self: A Visual Narrative Of A Process Of Individuation Through Artistic Practice, Stacie Becker

Graduate Studies Theses and Dissertations 2026

Reclaiming the Self: A Visual Narrative of a Process of Individuation Through Artistic Practice features a multidisciplinary practice that uses visual narrative, metaphor, and symbolism to reconcile the complex intersections of internal and external identity-shaping experiences, informed by lived experience as a woman. Working across painting, mixed media, printmaking, book arts, sculpture, and restorative medical tattooing, the artist dissects the tension between internal identity and external expectations, addressing themes of gender roles, relationships, trauma, and agency. Various artistic methods serve not only as a process but also as a parallel for reclaiming, healing, and restoring an authentic, unashamed sense of …

Two Essays On Geopolitical Risk And Investment Decisions, Jie Hu

Graduate Studies Theses and Dissertations 2026

My first essay studies how global institutional investors adjust cross-country equity allocations in response to rising geopolitical risk. Using quarterly equity holdings of institutional investors over 1997–2023, combined with news-based global and country-specific geopolitical risk indices, I find that following increases in geopolitical risk within a country, foreign institutions actively reduce their allocations in that country and the nearby region. Elevated global geopolitical uncertainty triggers both a flight-to-home response toward domestic equities and a flight-to-safety effect toward U.S. equities. Investor responses are heterogeneous: Institutions with higher geopolitical risk sensitivity respond more aggressively, whereas larger or better-performing hedge funds often maintain …

First Record Of Arrhenophagus Chionaspidis Aurivillius (Hymenoptera: Encyrtidae) Parasitizing White Mango Scale In Kenya: Its Potential Distribution And Prospects In Biocontrol, Francis Obala, Abdelmutalab G.A. Azrag, Rehemah Gwokyalya, Shepard Ndlela, Ingo Grass, Georg Petschenka, Sunday Ekesi, Samira A. Mohamed

All Peer-Reviewed Publications

The white mango scale, Aulacaspis tubercularis Newstead (Hemiptera: Diaspididae), is one of the most destructive pests of mango worldwide. Its current management in most of the invaded areas largely depends on the intensive use of chemical insecticides. Biological control using parasitoids represents one of the most effective and environmentally sustainable management options. However, in Kenya, one of Africa's leading mango-producing countries, no effective parasitoid species associated with A. tubercularis had previously been recorded. This study aimed to identify encyrtid parasitoids associated with A. tubercularis in Kenya, and to assess how bioclimatic factors influence their occurrence and habitat suitability. Mango leaves …

Stacked Risks, Unequal Returns: Stratified Risk Allocation In Housing And Higher Education, Regina M. Lewis

University of Kentucky Doctoral Dissertations

In the United States, public policy does more than distribute resources. It distributes risk. The same policy can create profoundly different consequences for different people because policies operate on landscapes shaped by generations of unequal investment and opportunity.

To explore this process, I introduce the Stratified Risk Allocation (SRA) Framework to demonstrate how facially neutral policies reproduce inequality by allocating risk across populations with unequal capacity to absorb it. Drawing on risk society theory, historical institutionalism, critical race theory, intersectionality, and stratification economics, the SRA framework distinguishes between Exposure, the likelihood of encountering policy-generated risk, and Capacity, the resources available …

Restructuring Actor Training For Psychological Wellbeing, Caroline C. Byce

Theses and Dissertations

This thesis highlights the importance of performer mental health as it relates to performance pedagogy. Based on a comprehensive review of traditional western actor training methods, survey data, and interviews, this research proposes a framework through which educators, directors, and performers alike can acknowledge both the artistic value and psychological harm prevalent in many prominent acting techniques. The insights put forth by this thesis extend beyond theatre acting and into television and film acting respectively, culminating in a series of practical steps -transferrable to any medium - for implementing a restructured and more human-centered approach to classrooms, workshops, and rehearsal …
