Decomposing Shadow Prices Under Climate-Driven Growth Scenarios: Insights From An Elk Herd Case Study, Ranjit Bawa, Drew Bennett, Wai Yan Siu, Bailey Kirkland, David Finnoff, Jacob Hochard

ODU Articles

Natural capital accounting provides a framework for integrating ecological processes with economic valuation, but the mechanics of shadow price formation often remain opaque to resource managers and policymakers. Using the Clarks Fork elk herd in northwestern Wyoming as a case study, we decompose the shadow price of natural capital into its ecological, economic, and institutional components. Population dynamics are estimated using a linearized Ricker model and projected forward using a logistic projection, incorporating climate-driven reductions in intrinsic growth rates. These ecological scenarios are linked to a shadow pricing formulation that explicitly accounts for marginal benefits, harvest policy responses, discounting, and …

Agricultural Productivity Under Energy Development: Insights From California, Wai Yan Siu, Sherzod B. Akhundjanov

ODU Articles

This paper examines how agricultural productivity patterns in Kern County, California, a leading region for both agricultural production and oil and gas development, co-vary with the spatial and temporal expansion of hydraulic fracturing and associated energy infrastructure. Using parcel- and county-level analyses, we characterize how agricultural productivity differs across proximity to energy development and across spatial scales. The results reveal spatially heterogeneous and scale-dependent patterns: parcel-level evidence indicates lower Enhanced Vegetation Index-based vegetation productivity within the 20-mile proximity zone around fracking wells, while county-level results show heterogeneous crop-specific yield changes during the post-expansion period. Together, these findings highlight the importance …

Exploring The Ephemeral: California’S Light And Space Artists, Shasta Power

Undergraduate Research Awards

Advancements in technology during the 20th and 21st centuries have allowed for new forms of art to be created, and new mediums to be explored— evidenced by the Light and Space Movement which emerged out of Southern California in the 1960s. Artists of this movement occupied a unique position within the larger scene of art history at the time; they were at the center of political turmoil and technological revolution, working in the same spaces and at times even alongside the engineers and psychologists interested in space: both outer and inner. Mary Corse, a painter, Fred Eversley, a sculptor, and …

Towards Novel Porphyrinoid Architectures: Synthesis Of Porphyrin Analogues With Two Six-Membered Exocyclic Rings, Amy L. Le, Timothy D. Lash

Faculty Publications – Chemistry

Tripyrranes with terminal ester protective groups were prepared by reacting 7-acetoxy-4,5,6,7-tetrahydroindoles with 3,4-diethylpyrrole in refluxing acetic acid-ethanol. Dibenzyl esters were deprotected by hydrogenolysis over 10% Pd/C and the resulting dicarboxylic acids were condensed with a series of dialdehydes in the presence of trifluoroacetic acid, followed by oxidation with FeCl₃ or DDQ, to give porphyrinoid products with two six-membered exocyclic rings. Reactions with a pyrrole dialdehyde gave porphyrins in 27-30% yield and good yields were also obtained using 2,5-furandicarbaldehyde and 4-hydroxy-2,6-pyridinedicarbaldehyde to prepare oxaporphyrins and oxypyriporphyrins. However, poorer results were noted for thiaporphyrins, benzocarbaporphyrins and oxybenziporphyrins due to their poor …

Rudolph, April M. Young, Golnaz Eftekhari Yazdi, William W. Thompson, Liesl M. Hagan, Liisa M. Randall, Jianing Wang, Rebecca Earnest, Shayla Nolen, Benjamin P. Linas, Joshua A. Salomon

Center on Drug and Alcohol Research Faculty Publications

People who inject drugs (PWID) account for the majority of hepatitis C virus (HCV) infections in the United States. The injection-equipment-sharing network likely plays an important role in shaping the dynamics of HCV transmission. Recognizing the emerging HCV epidemic in rural communities, we developed an agent-based network simulation model of HCV transmission via injection equipment sharing and used data on rural PWID networks to inform model parameterization and calibration. We then simulated an array of networks that varied key network properties to understand their impact on the magnitude and distribution of HCV incidence. The results show substantial heterogeneity in HCV …

Early-stage governance is often hindered by limited understanding of technological implications, rapid innovation cycles, and resistance from powerful industry actors who favor minimal oversight. Yet, timely and effective governance is essential, as new technologies are most malleable in their formative stages. This dissertation examines how emerging technologies can be governed effectively by using deepfakes technology as a focal case. This dissertation comprises three interrelated studies.

The first paper reviews the literature on deepfakes and emerging technology governance, identifying the distinct characteristics of deepfake technology …

The Relationship Between Culturally Responsive Teaching (Crt) Training, Teachers’ Children’S Book Choices, And Perceptions Of Censorship In Kuwait, Norma Gina Lombardi Sciarra

All Electronic Theses and Dissertations

Teachers who are culturally responsive use classroom materials that reflect their students' ethnicities, traditions, and values. Western teachers have access to diverse books and classroom tools. They have the agency to choose materials that support the curriculum. However, when Western educators work abroad, they must adapt their teaching methods and tools to local norms. Working abroad may require censoring or omitting information and content they believe in and support. As a result, teachers may feel dissonance or conflict when censoring. Censoring may impact their ability to teach comprehensively. Little research examines the relationship between culturally responsive teaching (CRT), perceptions of …

The Relationship Between Principals' Servant Leadership And The Retention Of Mid-To-Late-Career Elementary Teachers In Minnesota Public Schools, Teresa Widen

Teacher attrition, particularly among experienced educators, significantly impacts school stability and student outcomes. This quantitative study examined the relationship between mid-to-late-career elementary teachers’ perceptions of their principals’ servant leadership behaviors and their own retention decisions within Minnesota public schools. Grounded in servant leadership theory, the research also explored whether perceptions of leadership varied significantly based on teacher gender or teaching position. Utilizing a non-experimental, correlational design, data were collected via an online survey administering the Servant Leadership Scale and the Turnover Intention Scale (TIS-6). The final sample consisted of 410 experienced elementary teachers. Data were analyzed using JASP employing descriptive …

A Quantitative Analysis Of The Relationship Between Mentoring And Professional Development Outcomes Of Public Senior High School Teachers In Ghana’S Central Region, Frank Ayim

All Electronic Theses and Dissertations

This quantitative study examined the relationship between mentoring and teacher professional development among public senior high school teachers in Ghana’s Central Region. Although mentoring is widely promoted as a strategy for strengthening instructional quality, limited empirical research has investigated how specific dimensions of mentoring influence in-service secondary teachers within Sub-Saharan African contexts. Grounded in social cognitive theory and adult learning theory, this study addressed that gap by differentiating among structural participation in mentoring, duration of mentoring involvement, and mentorship participation intensity. A correlational research design was employed using validated instruments measuring mentoring engagement, instructional effectiveness, and classroom management. Data were …

An Analogue Of Carmichael Numbers, Or Six For Infinity, J.D. Phillips

Journal Articles

We find all non-negative integers n such that congruence modulo n is stable under exponentiation by positive integers, i.e. we show, that n = 1, 2, 6, 42, 1806 are the only numbers for which the condition a ≡n b and c ≡n d imply that a c ≡n b d , a, b, c, d ∈ N is satisfied. We also show in what sense this condition is close to the conditions for Carmichael numbers.

What Truly Drives Graduate Earnings?, Aiden Akbarov

High Impact Practices Student Showcase Spring 2026

The goal of my project, Predicting the Paycheck: What Factors Truly Influence Graduate Earnings?, was to see if we could actually predict a college graduate's starting salary using data instead of just guessing. I used a dataset of 172 majors from the American Community Survey to look at how a student's field of study, the gender balance of their major, and the current job market all impact their first paycheck. I wanted to create a tool that helps students understand the financial reality of their degree before they even graduate.

To get my results, I used a Multiple Linear Regression …

Do Developers Read Type Information? An Eye-Tracking Study On Typescript, Samuel W. Flint, Robert Dyer, Bonita Sharif

Research & Publications

Statically-annotated types have been shown to aid developers in a number of programming tasks, and this benefit holds true even when static type checking is not used. It is hypothesized that this is because developers use type annotations as in-code documentation. In this study, we aim to provide evidence that developers use type annotations as in-code documentation. Understanding this hypothesized use will help to understand how, and in what contexts, developers use type information; additionally, it may help to design better development tools and inform educational decisions. To provide this evidence, we conduct an eye tracking study with 26 undergraduate …

Automated Cerebral Autoregulation Monitoring With Machine Learning, Matteo Rosati

Yale Medicine Thesis Digital Library

Background - Current methods of identifying patients in the neurological intensive care unit (NeuroICU) with disrupted cerebral autoregulation rely on statistical methods that require significant time to produce predictions. There is a need for faster algorithms that can minimize the secondary damage caused by disrupted autoregulation in these patients.

Research Aims - We aim to develop a machine learning (ML) model that determines whether a patient is outside optimal autoregulatory limits using continuously recordable and minimally invasive physiologic data gathered in the NeuroICU.

Hypothesis - We hypothesize we can use ML techinques to ingest physiologic data in short time windows …

Neighborhood Embeddings And Scalable Learning For Optimal Transport And Unbalanced Optimal Transport, Muhammad S. Rana

Mathematics Dissertations - Archive

Dimensionality reduction techniques are developed from the assumption that high-dimensional data often arises from low-dimensional structures embedded into the high-dimensional ambient space. Classical dimensionality reduction methods rely on the Euclidean distance, which may fail to capture the geometric structures of the datasets. This dissertation includes alternative metrics for dimensionality reduction techniques and challenges in applying these techniques.

First, we investigate the Wasserstein distance based neighbor embeddings for dimensionality reduction methods and compare the classification and clustering performance with the classical Euclidean based methods. The Wasserstein distance models the data as probability distributions and compares two distributions applying optimal transport (OT) …

Estimating Prep And Voluntary Medical Male Circumcision Prevalence In Three High Hiv Burden Countries, Rose Grace Bender

Yale Medicine Thesis Digital Library

Understanding the impact of specific biomedical interventions is crucial for optimizing HIV prevention strategies. In this study, we estimate of the prevalence of voluntary medical male circumcision (VMMC) and lay out a framework for estimating preexposure prophylaxis (PrEP) in the three high-burden sub-Saharan African countries of Malawi, South Africa, and Zimbabwe. For VMMC, we use a cohort-based simulation framework to model circumcision prevalence in all males over time, allocating VMMC count data to cohorts over time. Model outputs are compared with survey and campaign data, and two parameters, the initial background circumcision prevalence and the age distribution of VMMC procedures, …

Epidermal Differentiation Disorders Across The Lifespan: Growth, Ophthalmologic, And Perinatal Manifestations, Caroline Echeandia-Francis

Yale Medicine Thesis Digital Library

Epidermal differentiation disorders (EDDs) are a heterogeneous group of inherited skin diseases characterized by impaired epidermal barrier function, scaling, and erythema. Although substantial progress has been made in identifying the genetic causes of EDD, long-standing clinical observations—including impaired growth, ectropion, and increased rates of preterm birth—remain poorly characterized across genotypes. The prevalence, severity, and clinical significance of these manifestations have not been systematically evaluated in large, genotype-stratified cohorts, limiting the ability to provide anticipatory guidance and tailored clinical care. This thesis seeks to (1) characterize growth trajectories in children with EDD and determine genotype-specific patterns of growth impairment; (2) assess …

An Exploration Of Student Approaches Towards Note-Taking In Medical School, Salah Eldein Elkattawy

Yale Medicine Thesis Digital Library

During medical school, students are exposed to a vast amount of knowledge they are expected to learn, understand, and apply to the care of patients. Various study strategies have been adopted by students over the years to facilitate this process, such as spaced repetition flashcards, the use of learning aids such as mnemonic devices, and the use of third-party resources to supplement their learning in the classroom. Instructors have also recognized the value in certain formats of classroom instruction, such as case-based learning or team-based learning, in keeping students more engaged and in reinforcing their learning in an interactive manner. …

In order to increase the pool of qualified individuals pursuing healthcare, innovative strategies are needed to increase interest in healthcare fields among youth. Prior research has identified that healthcare career interest is driven in part by motivational characteristics including interest in math and science, self-efficacy, and social factors like the expectations of parents and caregivers. Mentoring, career exploration, and informal learning have been identified as strategies that increase student interest in and commitment towards healthcare careers. This …

Export Controls As Intellectual Property Regulation, Doni Bloomfield

Faculty Scholarship

Export-control laws have long regulated information created outside of the U.S. government. Legal scholars have paid little attention to these national-security laws, and have not recognized that the government uses them specifically to assert a right to suppress information held in patent applications and trade secrets. In this Article, I present a new history of the relationship between export controls and intellectual property to show how the government regulates IP transfers, and how the state uses IP laws to national-security ends. Export-control laws regulate IP by controlling how people in the United States and beyond can share or use inventive …

Chapter 12 - Defensive Procedures Between Bind-Over And The Filing Of The Charging Paper, Anthony G. Amsterdam, Randy A. Hertz

Trial Manual for the Defense of Criminal Cases

Most States, by constitution or statute, require the prosecution of some or all serious crimes by indictment. The Fifth Amendment to the federal Constitution similarly requires that prosecutions for any “capital, or otherwise infamous crime [in the federal courts be by] . . . indictment.” The requirement is conceived principally as a protection to the defendant, and s/he may waive it. See, e.g., People v. Myers, 32 N.Y.3d 18, 20, 109 N.E.3d 555, 556, 84 N.Y.S.3d 406, 407 (2018) (upholding the validity of a defendant’s waiver of the right to indictment “[b]ecause Steven Myers and the court supervising his waiver …

Trial Manual for the Defense of Criminal Cases

There is a host of types of experts that may be useful in a criminal case. For some examples, see § 5.2 seventh paragraph supra.

Chapter 33 - Selecting The Jury At Trial: The Voir Dire, Anthony G. Amsterdam, Randy A. Hertz

Trial Manual for the Defense of Criminal Cases

The procedures described in §§ 32.3-32.3.4 supra carried the process of selecting a trial jury up to the point at which a panel of jurors is ushered into the courtroom on the day of trial. The final step in the process, by which the actual trial jurors (and alternates) are selected from the panel, is known as the voir dire examination. It is the stage at which a great number of criminal cases are won or lost. For a discussion of voir dire practices that are useful in selecting jurors who are most likely to give defendants a fair trial, …
