Active Galactic Nuclei Across Scales: From Blazar Jets To Dark Matter Halos, Stephanie Ann Podjed

Dartmouth College Ph.D Dissertations

Within ΛCDM, galaxies form and evolve within dark matter halos, with both central and satellite galaxies contributing to the total stellar mass content. Virtually every massive galaxy harbors a supermassive black hole (SMBH) at its center, with a small fraction of the population growing by actively accreting material; we call this an active galactic nucleus (AGN). The processes giving rise to an AGN phase (i.e., growth of a SMBH) releases enormous amounts of energy in the form of radiation, outflows, and relativistic jets that are able to significantly affect the formation and evolution of galaxies. Blazars are an extreme class …

Facts, Policy, And Discretion, F. Andrew Hessick, Carissa Byrne Hessick

Faculty Publications

Presidents, prosecutors, and judges often announce policies on how they will make discretionary decisions. These policies have met the criticism that discretion must be the product of an assessment of the particular facts of a case. Decisionmakers cannot base discretionary decisions on policy considerations, nor can they adopt policies stating how they intend to exercise their discretion. To do so, the argument goes, does not constitute an exercise of discretion, but rather an abdication of it.

This Article argues that this criticism misunderstands discretion. Discretionary decisions must rest on reasons, and reasons necessarily appeal to principles and policies that are …

Gendered Words And Patent Grant Rates: A Textual Analysis, Deborah R. Gerhardt, Miriam Marcowitz-Bitton, W. Michael Schuster, Avshalom Elmalech, Omri Suissa, Moshe Mash

Faculty Publications

Text is a vehicle to convey information that reflects the writer’s linguistic style and communication patterns. By studying these attributes, we can discover latent insights about the author and their underlying message. This article uses such an approach to better understand patent applications and their inventors.

While prior research focuses on patent metadata (i.e., filing year or gendered inventor names), we employ machine learning and natural language processing to extract hidden information from the words in patent applications. Through these methods, we find that inventor gender can often be identified from textual attributes—even without knowing the inventor’s name. This ability …

Government Religious Speech And The Establishment Clause, Mark Storslee, Michael Helfand

Faculty Publications

The government says religious things. From monuments and holiday displays to legislative prayers, religion saturates the government’s public voice. But how can that be permissible when the Establishment Clause, at least in theory, indicates the government should be religiously neutral?

So far, the Supreme Court’s attempts to address the puzzle have come up short. Early on, the Court suggested that seemingly all government speech must be secular, or that it refrain from “endorsing” religion. But the Court never consistently enforced those limits, struggling to reconcile them with America’s historical experience. And in recent years, the Court has rejected those approaches …

The End Of Territoriality?, Reuven S. Avi-Yonah

Articles

The One Big Beautiful Big Act (OBBBA) of 2025 is generally consideredto be a continuation of the Tax Cuts and Jobs Act (TCJA) of 2017.1Thatis definitely true as far as the individual tax provisions are concerned, be-cause the OBBBA merely made permanent the TCJA provisions with minorchanges, such as increasing the cap on the state and local tax deduction from$10,000 to $40,000. For the corporate tax, the OBBBA continued some of thechanges in the TCJA (such as expensing) while relaxing others (such as amorti-zation of research and experimentation (R&E) expenditures and a stricter limiton interest deductions) without changing the overall …

Merger Remedies Unbound, Dhruv Aggarwal, Albert H. Choi, Geeyoung Min

Articles

How should foundational contract law doctrines apply to corporate mergers? This Article argues that recent changes in Delaware law grant parties expansive contractual freedom to define their preferred remedies in merger agreements, untethered from the limits imposed by traditional contract law. A new provision in the Delaware corporate code, or the Delaware General Corporation Law (DGCL), permits penalty clauses in merger agreements, notwithstanding the traditional “anti-penalty doctrine” that forbids punitive liquidated damages in contracts. Delaware courts have also shown deference to specific performance provisions, treating them as presumptively enforceable commitments instead of retaining their traditional judicial discretion over the choice …

States As Gatekeepers In Global Governance, Kristina Daugirdas

Articles

Over the last several decades, private actors—corporations, philanthropic foundations, and non-governmental organizations—have increasingly contributed to the development and implementation of public international law. In some cases, private actors are developing standards that serve as substitutes for public regulation. In other cases, private actors have been “invited in” to public international organizations as funders, accredited observers and consultants, and even representatives of member states. According to one estimate, 56 percent of international organizations offered some form of access to private actors in 1990; two decades later, more than 90 percent did.

What we are witnessing, in other words, is the growing …

Monitoring, Oversight, And Learning In Medical Ai, W. Nicholson Price Ii

Articles

When medical AI errs, it often goes unnoticed. If there’s a specific patient injury, and the link to AI is obvious, that problem might be reported to the Food and Drug Administration (FDA), but not always. And many other types of problems, like worse performance on specific groups or ineffective integration into health system workflows, simply don’t fall within the contours of regularized reporting. Even if they are noticed by the health system—far from a given—there’s no obvious way to share that information more broadly. Against this backdrop, there are justified calls for better oversight and reporting. But there’s the …

The Crisis Of Appropriations Law, Samuel R. Bagenstos

Articles

Appropriations law is a unique body of federal law.  Appropriations law imposes its own somewhat baroque set of statutory interpretation principles, approves of very broad delegations to the Executive Branch without meaningful limiting principles, and is often exempt from judicial review.  But perhaps that is all about to change.  Donald Trump’s historically aggressive challenge to Congress’s power of the purse has spurred an unusually large volume of exceptionally high-stakes appropriations law litigation. 

The potential implications go beyond the high-profile issues such as enforcement of the Impoundment Control Act.  In general, the unusual features of appropriations law are built on a …

Read But Not Understood? An Empirical Analysis Of Consumer Comprehension In Homeowners Insurance, Daniel Schwarcz, Brenda J. Cude, Kyle D. Logue, German Marquez Alcala

Articles

Modern contract law assumes that consumers meaningfully assent to the standard forms that govern their daily lives. However, this assumption is widely regarded as a legal fiction for two key reasons: first, most consumers do not read standard forms, and second, even those who do often struggle to fully comprehend their terms and implications. Although the lack of consumer reading has been well documented through empirical research, consumers’ ability to comprehend standard-form contracts has received surprisingly little attention.

This Article addresses the latter issue by empirically examining whether providing excerpts from the dominant standard-form homeowners insurance policy improves consumer understanding …

Authorship Nonsense, Jessica Litman

Articles

Copyright law’s primary device for promoting progress is to bestow rights on the authors of works. Rights vest automatically and last for a very long time. Authors’ choices to retain, license, or transfer those rights fuel opportunities to communicate the works to their audiences. The copyright system’s mechanisms for determining who authored works (and therefore automatically obtained copyright rights) should be both accurate and reliable, since misidentifications will undermine the law’s working as intended.

This article examines authors’ creation of works and copyright law’s handling of authorship disputes. Many works result from creative collaboration. Although the copyright statute incorporates mechanisms …

Useful Noise: Understanding Dicta And Knowing What To Do With It, Len Niehoff, Tucker Gribble

Articles

Sometimes we approach the idea of obiter dictum as if it were Latin for “Here the court says something I wish it didn’t.” When a judicial opinion includes a statement that hurts our case, we labor to cast it as dicta and we give it the first name “mere.” If the opposing party quotes the statement, we huff about its irrelevance and dismissively proclaim that it can, indeed must, be ignored. We treat dicta as background noise, and we encourage the court to plug its ears and hum.

How The U.S. Constitution Shapes International Tax Law: Instrument Choice In Tax Agreements, Noam Noked, Young Ran (Christine) Kim, Reuven Avi-Yonah

Articles

The U.S. Constitution’s Treaty Clause, which requires Senate approval by a two-thirds vote for treaties, has significantly influenced the development of international tax law. This Article examines the implications of Senate supermajority requirements on bilateral and multilateral tax treaties and agreements, alternative instruments, relevant international tax standards, and global tax governance.

Historically, tax treaties have been approved exclusively as Article II treaties requiring Senate approval. The difficulty of entering into treaties with the United States has influenced the instrument choice and design of U.S. and international tax standards. To address this challenge, several U.S. and international tax reforms have employed …

Putting The L In Elsi: Legal Methods For Bioethics Research, Anya E R Prince, Benjamin Berkman, Donald Ford, Dov Fox, Christi Guerrini, Amy Koopmann, Natalie Ram, Jessica L Roberts, Kayte Spector-Bagdady, Sonia Suter

Center for Medical Ethics and Health Policy Staff Publications

Lawyers and law professors are increasingly involved in interdisciplinary scientific teams and grant research to answer ethical, legal and policy questions related to biomedical topics. Yet, the methods that lawyers use to conduct legal research and analysis are not always familiar to scientists and social scientists conducting peer review of a proposed project with legal aims or a publication reporting a legal study. To better facilitate interdisciplinary ethical, legal, and social implications collaboration, there is a need to better explain how legal research methodologies can provide robust tools to address a range of nuanced biomedical questions. This paper explores …

Differences Between Government, Consortium, And Private Database Stewards Impacting The Genomic Data Market: A Survey Of U.S. Academic Genetic Researchers., Amanda K Greene, J Denard Thomas, Kaitlyn Jaffe, Luyun Chen, Kerry A Ryan, Brian J Zikmund-Fisher, J Scott Roberts, Amy L Mcguire, Katherine Hendy, Kayte Spector-Bagdady

Center for Medical Ethics and Health Policy Staff Publications

Background: Despite major shifts in U.S. federal government data sharing requirements, their impact, and relation to researcher choice of database, are underexplored. This study surveyed genetic researchers regarding trends, priorities, perceptions of quality, impact on research outcomes, and genomic data sharing and use across government, consortium, and private databases.

Methods: As part of an exploratory sequential mixed methods project, we surveyed 294 U.S.-based genomic academic researchers.

Results: Genetic researchers generally have a choice between databases, which allows them to prioritize data quality. This might explain recent trends toward the use of government and consortium databases away from private ones. Respondents …

Prom: Protection Against Reverse Engineering Attacks Through Programmable Logic Macros, Pravin Gaikwad, Aritra Dasgupta, Sudipta Paria, Peyman Dehghanzadeh, Jonathan Cruz, Swarup Bhunia

Electrical Engineering and Computer Science Faculty Publications

The modern supply chain ecosystem exposes hardware intellectual property (IP) blocks to diverse confidentiality attacks aimed at reverse engineering (RE), piracy, or the extraction of design secrets. An emerging and potent design solution for IP protection against these attacks, particularly against RE, is the fine-grained redaction of security-critical logic and replacing the redacted logic with lookup tables (LUTs). The LUTs are then programmed in-field, similar to FPGAs, using protected bitstreams, thereby preventing untrusted foundries or test/assembly facilities from mounting RE attacks. The LUT-based redaction paradigm incurs a substantial hardware cost, with area overhead ranging from 70x to 100x and delay …

A Quantum Algorithm For Multidimensional Partial Differential Equations With Practical Case Studies, Manu Chaudhary, Kareem El-Araby, Devon Bontrager, Alvir Nobel, Shima Mohaghegh, Kieran Egan, Mainish Singh, Trey Campbell, Jacob Spry, Luis Aviles, Naveed Mahmud, Pranav Reddy, Pruthviraj Sadhankar, Shivansh Shrivas, Esam El-Araby

Electrical Engineering and Computer Science Faculty Publications

Partial differential equations (PDEs) play a central role in scientific and engineering analysis, with applications spanning fluid dynamics, heat and mass transfer, electromagnetism, quantum mechanics, and financial modeling, where they are used to describe diffusion processes, wave propagation, and the evolution of complex systems over space and time. Solving multidimensional partial differential equations (PDEs) is a computationally challenging problem, even for the most advanced classical systems. Over the past decade, quantum computing has attracted significant interest as a potential approach for solving complex computational problems, including multidimensional PDEs. Although a variety of approaches have been proposed for solving PDEs, most …

Counting Constraints In Pomdps Based On Pid Controllers, Garrett Gmeiner, Patrick Quinn, Asmaa Alqurashi, Prem Swaroop Pochiraju, Mirajul Islam, Jackson Contreras, Sajina Pathak, Rwaida Alssadi, Sumana Boyapalli, Raghavendra Mallesha, Vijay Uppalapati, Javier Laboy-Jusino, Nikiraj Konwar, Muntaser Syed, Marius Silaghi

Electrical Engineering and Computer Science Faculty Publications

A Bayesian architecture is proposed for integrating counting constraints in the process of decision making with Partially Observable Markov Decision Models for robotics. In addressed problems, the counted events are detected with noisy sensors, making their detection uncertain. We handle their count as a random variable to be updated on observations. In our test scenario, an iRobot Create3 moves along a hallway and needs to count how many doors it passes while following the wall. After detecting that the given number of doors have been passed, the robot should turn around and return to the starting region. For this kind …

Exploring Parent-Child Reminiscing Style And Internal-State Talk When Discussing Positive And Negative Shared Events, Komal Verma Miss.

Theses and Dissertations (Comprehensive)

Conversations between parents and children about past events play a critical role in children’s social, emotional, and cognitive development. Parents scaffold their children in learning to recount details of their autobiographical memories by creating a space to reflect on internal states, specifically emotions and cognitions. Parents with an ‘elaborative’ reminiscing style are responsive to children’s utterances and ask open-ended questions (e.g., What do you remember about...?). Parents who are less ‘elaborative’ typically ask narrow questions like Did you like it?” that do not encourage conversation. Children whose parents use an elaborative reminiscing style have children who produce the most detailed …

Exploring Engagement With The Ecoschools Platform: An Interactive Display Board Exploratory Evaluation, Kaitlyn E. Ashmore

Theses and Dissertations (Comprehensive)

This study explores strategies to enhance engagement with EcoSchools Canada, an online sustainability platform used across Canada. Through an exploratory case study involving two Waterloo Region District School Board (WRDSB) schools, the research evaluates the effectiveness of interactive tools such as an Interactive Display Board (IDB) and action cards in fostering student engagement, self-efficacy, and action competence in sustainability initiatives. Through examining user experiences and feedback from Eco-teams and staff, the findings aim to identify if and how these interventions serve as valuable complements to EcoSchools activities. Although not a standalone solution, these tools facilitate deeper involvement when integrated within …

Nanoparticle Carriers Enhance The Prophylactic Antiviral Effects Of Dsrna In Vitro And Ex Vivo, Shayne Oberhoffner, Stephanie Dewitte-Orr, Starla Richardson, Leah Haile, Dominique Daniels, Erin Cooper, Aizah Ijaz, Janet Velasquez Perez, Mathilde Peruzzi, Bertrand Collet, Paul Craig, Kristof Jenik

Theses and Dissertations (Comprehensive)

Aquaculture now outpaces traditional capture fisheries as the world population and demand for sustainable protein sources increases. Wild and farmed species are increasingly susceptible to pathogen spread as global temperatures rise and stocking densities increase. Despite the devastating losses experienced by aquaculture due to viral infections, there remain few effective prophylactic antiviral therapeutics. Long double-stranded (ds)RNA is a uniquely viral molecule produced by nearly all viruses during their replication cycle, and its detection by salmonids like rainbow trout (Oncorhynchus mykiss) and chinook salmon (Oncorhynchus tshawytsha) leads to the establishment of a defensive antiviral state. Previous in vitro studies demonstrated a …

Envisioning The Role Of Community-Owned Stores & Aligning Federal Food Policies: A Participatory Approach To Food Security And Food Sovereignty In Sambaa K’E, Denendeh (Northwest Territories, Canada), Narayan Subramoniam

Theses and Dissertations (Comprehensive)

Northern Indigenous communities have relied on traditional food systems for meaningful, nutritious diets since time immemorial. But many Indigenous communities in remote northern regions of Canada still face disproportionately elevated levels of food insecurity due to climate change radically altering the availability for traditional foods, colonial food policies imposing Western diets, and the high costs of transporting store-bought foods. Extreme weather events such as wildfires further isolate fly-in remote communities increasing both the costs of transporting store-bought foods and the difficulties of harvesting traditional foods. There are many examples of community-based initiatives for supporting traditional and locally grown foods, however, …

Children's Peer Selection In Stem: The Influence Of Gender, Ethnicity, And Disability, Meagan Girard, Kim P. Roberts

Theses and Dissertations (Comprehensive)

The present study examined how children’s peer selection in STEM (science, technology, engineering, and mathematics) may be influenced by gender, ethnicity, and physical disability. Sixty-four children (ages 6-12) from elementary schools in Southwestern Ontario completed three tasks: a simulated peer selection task, an attribution of ability task, and a stereotype belief questionnaire. In the peer selection task, participants were repeatedly asked to select one peer from a set of AI-generated photographs showing children who differed by gender (male, female), ethnicity (White, Black, East Asian), and physical disability status (able-bodied user vs. nondisabled). The Peer Selection Task was based on the …

Injury To Insight: Exploring The Influence Of Media On Acl Rehabilitation Experiences Of Female Soccer Players, Chynna Ho-Young Cadogan, Jill Tracey

Theses and Dissertations (Comprehensive)

Participation in soccer inherently carries a risk of injury, with female athletes facing a significantly higher susceptibility to anterior cruciate ligament (ACL) injuries (Campbell et al., 2014; Le et al., 2025; Silvers-Granelli, 2021). The increasing participation in women’s soccer, coupled with the growing demand for its consumption through spectatorship, has contributed to a rise in ACL injuries, and increase in media coverage on this phenomenon (Parsons et al., 2021). Understanding how media narratives surrounding ACL injuries and recovery may influence rehabilitation experiences can educate coaches, mental performance consultants, athletic therapists, and female soccer players to better understand and navigate ACL …

Multivariate Quantile Autoregression-Mixed Data Sampling (Mvqar-Midas) Modeling Of Cost Of Living And Supply Chain Dynamics In Canada., Patrick Gbolonyo

Theses and Dissertations (Comprehensive)

In recent years, the rising cost of living as a result of persistent inflationary pressures, disruptions in the global supply chains, and changes in the macroeconomic landscape has become a critical topic of discussion. To address this, we move beyond a mean-based framework and employ a quantile regression approach. This allows the persistence of each series and the transmis- sion of shocks between the Consumer Price Index (CPI) (the total CPI which is a percentage change over the past 12 months), the Interest Rate (IR)(the target for the overnight rate), the New Housing Price Index (NHPI), and high-frequency supply chain …

Science Fiction Cinema And The Technological Sublime: Spectacle And The Infinite From Early Cinema To Digital, David Jackson Dr.

Theses and Dissertations (Comprehensive)

This dissertation examines how science fiction cinema constructs and reimagines the technological sublime in the twentieth century: the experience of awe, terror, and admiration provoked by human-made power and scale. Drawing on the philosophical foundations of the sublime in Edmund Burke and Immanuel Kant and extending through Leo Marx’s and David E. Nye’s theorization of the technological sublime, I propose an aesthetic mode in which representation inflected with affect translates technological spectacle into examinations of humanity’s role and agency in the face of overwhelming technologized worlds and in some cases, even the universe itself.

Through three distinct historical periods …

Exploring Leadership In A Changing Church, Tanya Varner

Theses and Dissertations (Comprehensive)

The present phenomenological study investigated the experience of leaders and leadership among active Lutheran clergy serving congregations in the Eastern Synod of the ELCIC in a time of change. Eleven rostered leaders of the Eastern Synod of the Evangelical Lutheran Church in Canada (ELCIC) were interviewed individually using a semi-structured interviews addressing leadership and changes in the church to facilitate the conversation. Participants also completed a participant questionnaire in advance of the semi-structured interview to make sure the sample was diverse in gender, years of ordination and geographical context of ministry. Participants were able to articulate what values and requirements …

Eeg Correlates Of Tactile Synchrony, Devon K. R. Gallagher

Theses and Dissertations (Comprehensive)

New research on the tactile system has suggested that cortical representations of body parts are not fixed, as previously thought, and are instead dynamically maintained through constant sensorimotor information and feedback. Within the somatosensory cortex (S1), the capacity for both permanent and temporary changes have been the topic of ongoing research. The current study aimed to corroborate whether 24 hours of a finger adhesion manipulation is sufficient to elicit behavioural and electrophysiological correlates from cortical reorganization of digit representations in S1, using a behavioural paradigm outlined by Kolasinski et al. (2016). Through electroencephalography (EEG) recording during a tactile discrimination task, …

Methylseleninic Acid Transformations In Nutrient Rich Water Containing Algae Exposed To Simulated Sunlight, Mikayla Cormier

Theses and Dissertations (Comprehensive)

Methylseleninic acid (MSA(IV)) is an organic form of selenium that has been suggested to be one of the most bioaccumulative forms of selenium in aquatic ecosystems. However, there have been no lab studies that confirm this, which is the reason this study was conducted. Once MSA(IV) and other bioavailable forms of selenium enter aquatic ecosystems, organisms such as algae take up these compounds which then bioaccumulate through the food chain. S. obliquus was exposed to 10 ppb MSA(IV) in 10% Bold’s basal medium (BBM) in a growth chamber to mimic environmental conditions over a 7-day period. Carbon traps and filters …

Cognitive Load Classification Using Functional Near-Infrared Spectroscopy, Pratham Shah

Theses and Dissertations (Comprehensive)

This thesis investigates the classification of cognitive load using functional near-infrared spectroscopy (fNIRS) signals recorded during an N-back working memory task. The study introduces a novel short-channel correction layer designed to suppress superficial physiological noise adaptively, addressing limitations of traditional General Linear Model (GLM) based regression. A single participant dataset comprising 69 validated sessions was analyzed using both conventional machine learning and deep learning approaches. Traditional classifiers: Linear Discriminant Analysis (LDA), Support Vector Machines (SVM), Random Forests, and Gradient Boosting were first evaluated using statistical features (mean, variance, peak, and slope). Among these, Gradient Boosting achieved the highest accuracy (55.6%), …
