On The Nature Of Artworks: An Argument For Artwork Universals, Emma H.B. Rosenberg Jan 2025

On The Nature Of Artworks: An Argument For Artwork Universals, Emma H.B. Rosenberg

Scripps Senior Theses

What kind of a thing is an artwork? Artworks are an extensive, complex category including all manner of media and content. This makes the project of determining what artworks themselves are a significant challenge. Nevertheless, there are many things we intuitively desire to say about what artworks are like and what value they offer. One underexplored theory which I will here argue successfully accommodates many of these features is that of artworks as universals.

It is not my aim in this thesis to compare this theory with other, rival theories of artworks. Rather, I will argue that the theory supports …


A Proof Of Np-Completeness For The K-Means Clustering Algorithm, Brooke C. Feinberg Jan 2025

A Proof Of Np-Completeness For The K-Means Clustering Algorithm, Brooke C. Feinberg

Scripps Senior Theses

The k-means clustering algorithm is one of the most widely used clustering techniques in data analysis and machine learning, yet its exact computational complexity remains subject to ongoing theoretical investiga- tion. This work establishes the NP-completeness of k-means by proving (1) it is NP-hard and (2) it lies in NP. To demonstrate NP-hardness, we construct a series of polynomial-time reductions from well-known NP-complete problems. Specifically, we reduce 3sat to Vertex Cover, and then reduce Vertex Cover to k-means, thereby establishing the computational hardness of the k-means clustering problem. We then prove k-means is in NP, and thus conclude it is …

A Knowledge-Based Planning Model To Identify Fraction-Reduction Opportunities In Brain Stereotactic Radiotherapy, Shane Mccarthy, William St. Clair, Damodar Pokhrel Jan 2025

A Knowledge-Based Planning Model To Identify Fraction-Reduction Opportunities In Brain Stereotactic Radiotherapy, Shane Mccarthy, William St. Clair, Damodar Pokhrel

Radiation Medicine Faculty Publications

Objective: To develop and validate a HyperArc-based RapidPlan (HARP) model for three-fraction brain stereotactic radiotherapy (SRT) plans to then use to replan previously treated five-fraction SRT plans. Demonstrating the possibility of reducing the number of fractions while achieving acceptable organs-at-risk (OAR) doses with improved target biological effective dose (BED) to brain lesions. Methods: Thirty-nine high-quality clinical three-fraction HyperArc brain SRT plans (24–27 Gy) were used to train the HARP model, with a separate 10 plans used to validate its effectiveness. Fifty-eight five-fraction HyperArc brain SRT plans (30–40 Gy) attempted to be retrospectively replanned for three fractions scheme using the HARP …


An Investigation Into The Feasibility And Efficacy Of Stereotactic Radiosurgery For 1–3 Cm Single Brain Lesions On The Ring-Mounted Halcyon Linac, Kristin J. Hazelwood, Shane Mccarthy, Josh Misa, David Castelvetere, William St. Clair, Damodar Pokhrel Jan 2025

An Investigation Into The Feasibility And Efficacy Of Stereotactic Radiosurgery For 1–3 Cm Single Brain Lesions On The Ring-Mounted Halcyon Linac, Kristin J. Hazelwood, Shane Mccarthy, Josh Misa, David Castelvetere, William St. Clair, Damodar Pokhrel

Radiation Medicine Faculty Publications

Purpose: An evaluation of the accuracy, safety, and efficiency of the Halcyon ring delivery system (RDS) for stereotactic radiosurgery (SRS) treatment to relatively small (1–3 cm) brain lesions.

Methods: After completing the extensive in-house quality assurance checks including Winston–Lutz test and independent dose verification via MD Anderson IROC SRS head phantom irradiation on Halcyon, fifteen brain SRS patients previously treated with a single dose of 20 Gy on TrueBeam (6MV-FFF) with HyperArc geometry were retrospectively replanned on Halcyon (6MV-FFF). Plan quality metrics including conformity index (CI), gradient index (GI), gradient distance (GD), PTV coverage, gross tumor volume (GTV) dose, heterogeneity …


A Predictive Quality Assurance Model For Patient-Specific Gamma Passing Rate Of Hyperarc-Based Stereotactic Radiotherapy And Radiosurgery Of Brain Metastases, Shane Mccarthy, Brent Harrison, Damodar Pokhrel Jan 2025

A Predictive Quality Assurance Model For Patient-Specific Gamma Passing Rate Of Hyperarc-Based Stereotactic Radiotherapy And Radiosurgery Of Brain Metastases, Shane Mccarthy, Brent Harrison, Damodar Pokhrel

Radiation Medicine Faculty Publications

Objective: Measurement-based patient specific quality assurance (PSQA) is an increasingly debated topic among medical physicists. Developments like online adaptive radiotherapy and same-day stereotactic treatments limit the time to do measurement-based PSQA. Herein, we develop a predictive machine learning model to supplement PSQA by predicting the gamma passing rate (GPR) per stereotactic arc. This streamlines PSQA, providing planners the insight to replan potentially sub-optimal plans, to mitigate machine time inefficiencies.

Methods: 122 patients that had previously received HyperArc stereotactic radiosurgery/radiotherapy on a TrueBeam LINAC (Millenium 120 MLCs, 6MV-FFF) were used to generate a long short-term memory (LSTM) recurrent neural network to …


Automated Hippocampal Sparing Whole Brain Radiotherapy With Simultaneous Integrated Boost For Multiple Brain Metastases: Halcyon, Hyperarc On Truebeam, And Coplanar Truebeam, Shane Mccarthy, Ryan Clark, Anthony Magliari, William St. Clair, Damodar Pokhrel Jan 2025

Automated Hippocampal Sparing Whole Brain Radiotherapy With Simultaneous Integrated Boost For Multiple Brain Metastases: Halcyon, Hyperarc On Truebeam, And Coplanar Truebeam, Shane Mccarthy, Ryan Clark, Anthony Magliari, William St. Clair, Damodar Pokhrel

Radiation Medicine Faculty Publications

Purpose: To demonstrate the ease and feasibility that hippocampal sparing whole brain (WB) simultaneous integrated boost (HSWB-SIB) plans can be generated using knowledge-based planning and Eclipse Scripting Application Programming Interface (ESAPI) for three different modalities, HyperArc on TrueBeam (TB-HA), a coplanar beam arrangement on TrueBeam (TB-Co), and the ring-mounted Halcyon LINAC (Hal).

Methods: Twelve patients with 2–14 brain metastases were retrospectively replanned for HSWB-SIB using a published HSWB RapidPlan model with modifications for the automated addition of SIB to metastases. Prescribed dose was 30 Gy to the WB planning target volume (PTV) and 50 Gy to the metastases in 10 …


Feasibility Of Treatment Planning With Hyperarc Stereotactic Radiosurgery Methods For Ocular Tumors, Chase Cochran, Shane Mccarthy, William St. Clair, Damodar Pokhrel Jan 2025

Feasibility Of Treatment Planning With Hyperarc Stereotactic Radiosurgery Methods For Ocular Tumors, Chase Cochran, Shane Mccarthy, William St. Clair, Damodar Pokhrel

Radiation Medicine Faculty Publications

Purpose/objectives

Currently, ocular disease is primarily managed with COMS plaque brachytherapy. Various stereotactic radiosurgery (SRS) platforms have also been employed, yet widespread access remains a challenge. Herein, we demonstrate the feasibility of using the HyperArc SRS system to provide an additional platform for the treatment of ocular malignancies.

Materials/methods

Twenty previously treated COMS patients with ocular melanoma were selected for a retrospective HyperArc SRS planning study. The average gross tumor volume (GTV) derived from MRI was 1.19 ± 0.60 cc. Planning target volumes (PTV) were generated from a 2 mm expansion of the GTVs. HyperArc plans were created for a …

The Challenge That The Advent Of Artificial Intelligence (Ai) Tools Poses To The Procedures For Determining The Existence Of The Preliminary Facts That Condition The Admissibility Of Items Of Evidence, Edward J. Imwinkelried Jan 2025

The Challenge That The Advent Of Artificial Intelligence (Ai) Tools Poses To The Procedures For Determining The Existence Of The Preliminary Facts That Condition The Admissibility Of Items Of Evidence, Edward J. Imwinkelried

Marquette Law Review

“[A]d quæstionem facti non respondent judices; . . . ad quæstionem juris not respondent juratores.” Judges do not answer questions of fact; jurors do not answer questions of law.

The jury is a central institution in the American level infrastructure. The Sixth and Seventh Amendments elevate the jury trial right to constitutional status. Of course, when a judge presides at a jury trial, the question that naturally arises is the division of decision-making labor between judge and jury. In the past few decades, the Supreme Court’s Apprendi v. New Jersey line of authority has expanded the jury’s authority to decide …


Don’T Trust The Process: The Viability Of Eighth Amendment Claims For Ultra-Processed Food Overconsumption In Prisons, Markus C. Johnson, Rita L. Rahoi-Gilchrest Jan 2025

Don’T Trust The Process: The Viability Of Eighth Amendment Claims For Ultra-Processed Food Overconsumption In Prisons, Markus C. Johnson, Rita L. Rahoi-Gilchrest

Marquette Law Review

With the largest prison population worldwide, American prisons serve more food than anywhere else. To cut costs, American prisons overwhelmingly (or even entirely) serve prisoners ultra-processed foods, which, if overconsumed, have detrimental and long-lasting health effects. Prisoners taking issue with the food being served to them rely on the courts to counteract any inappropriate prison dietary practices, wielding the Eighth Amendment as a constitutional guarantee to be free from cruel and unusual punishment. But courts are failing to protect this constitutional guarantee by relying on precedent that is at odds with modern Eighth Amendment principles. Indeed, when it comes to …


Boden Lecture: Taxation Of Autonomous Artificial Intelligence, Reuven Avi-Yonah, Lucas Brasil Salama, Herbert Snitz, W. Robert Thomas Jan 2025

Boden Lecture: Taxation Of Autonomous Artificial Intelligence, Reuven Avi-Yonah, Lucas Brasil Salama, Herbert Snitz, W. Robert Thomas

Marquette Law Review

This Article proposes that tax can be a useful supplement to other measures to regulate Autonomous Artificial Intelligence (AAI) and limit its potential harmful effects. This proposal differs from command-and-control regulation of AAI along the lines of European Union legislation that may unduly limit the development of AAI. It also differs from existing proposals to tax AAI to generate revenue to help workers displaced by AAI programs, or to tax the data used by AAI. The proposal is based on granting AAI programs like ChatGPT separate legal personhood, like corporate personhood, while incentivizing or requiring their corporate owner to place …


Substituting One Judge For Another: The Lax Standard Of Review In Involuntary Commitment, Caitlin Riordan Jan 2025

Substituting One Judge For Another: The Lax Standard Of Review In Involuntary Commitment, Caitlin Riordan

Marquette Law Review

Wisconsin involuntarily commits individuals at a rate nearly five times the national average, stripping them of core constitutional rights—including liberty, the ability to refuse treatment, and firearm possession. Yet, when these life-altering orders are appealed, they are almost always reviewed by a single appellate judge. This Comment argues that such a limited review undermines the constitutional weight of involuntary commitments, which closely mirror criminal convictions in the scope of rights deprived. Tracing the historical development of Wisconsin’s civil commitment statutes, this Comment demonstrates how commitments implicate both substantive and procedural due process concerns. It then compares Wisconsin’s one-judge review framework …


Tik Tok! Tiktok: Escalating Tension Between U.S. Privacy Rights And National Security Vulnerabilities, Lawrence J. Trautman Jan 2025

Tik Tok! Tiktok: Escalating Tension Between U.S. Privacy Rights And National Security Vulnerabilities, Lawrence J. Trautman

Marquette Law Review

Vastly popular short-form video provider TikTok employs personalized content algorithms for each consumer. Because TikTok is controlled by the Chinese Communist Party (CCP) of the People’s Republic of China, a legitimate question exists whether TikTok constitutes a national security risk to the West like a number of influential and successful high growth social media platforms that have been used by nation-states during recent years for propaganda and disinformation purposes. Cyberattacks upon American interests have been attributed to China, Iran, North Korea, Russia, and others. Well-documented examples of foreign activity and exploitation resulting from disruption of the U.S. elections since 2016 …


Public Private Property, Xiaoqian Hu Jan 2025

Public Private Property, Xiaoqian Hu

Marquette Law Review

Many struggles are being fought in America today around regulation and redistribution of private property rights: between owners’ right to develop land and society’s need for environmental conservation; between landlords’ privilege to charge higher rents and society’s need for affordable housing, between property owners’ desire for protection from negative effects and unhoused persons’ need to live in the only space accessible to them, etc. These struggles, however, are doomed by a widely shared notion that public and private are inherent qualities in a zero-sum game. This Article refutes this notion. Building upon Legal Realist, post-Realist, and poststructuralist insights, it argues …

Identification Of Pharmacophore Modifications That Enhance Bmp-Receptor Agonism, An Investigation To Understand The Development Of Potential Therapeutic Interventions, Maleka T. Stewart Jan 2025

Identification Of Pharmacophore Modifications That Enhance Bmp-Receptor Agonism, An Investigation To Understand The Development Of Potential Therapeutic Interventions, Maleka T. Stewart

Theses and Dissertations

Bone morphogenetic proteins (BMPs) are the largest subfamily of the Transforming Growth Factor (TGF)-ß superfamily. BMPs are renowned for their pivotal role in cellular functions such as cell growth, apoptosis, and differentiation. Yet, BMPs have also been attributed to the maintenance of adult tissue homeostasis. BMPs elicit physiological function at the cell membrane via a heterotetrameric complex composed of two Type I and two Type II serine-threonine kinase BMP receptors. Activation of BMP transmembrane receptors results in activation of either canonical (Smad-dependent) and/or non-canonical (Smad-independent) signaling. Given the physiological importance of this intricate communication between receptor activation and induction of …

Corporate Scenarios: Drawing Lessons From History, Madison Condon Jan 2025

Corporate Scenarios: Drawing Lessons From History, Madison Condon

Seattle University Law Review

As corporations are increasingly pressed to reveal information about their exposure to climate-related risks, they are often asked to undertake and disclose the outcome of “scenario analysis.” In this exercise, corporations, including financial institutions, examine how their business would fare under different pathways the future may take. One oft-used scenario, for example, is the International Energy Agency’s “Net-Zero by 2050: A Roadmap for the Energy Sector.” This Essay presents a history of the use of scenarios as a corporate planning tool, particularly in the oil industry, arguing that it is key for understanding our present moment and the role of …


Dark Accounting Matter, Colleen Honigsberg Jan 2025

Dark Accounting Matter, Colleen Honigsberg

Seattle University Law Review

Physicists calculate that approximately 85% of the matter in the universe is composed of “dark matter” that “does not absorb, reflect, or emit electromagnetic radiation and is therefore difficult to detect.” The S&P 500 currently trades at a price-to-book value of 4.2, suggesting that book value accounts for less than 20% of the S&P 500’s market value. The remaining 80% appears nowhere in these firms’ balance sheets—it is invisible to contemporary accounting techniques and constitutes “dark accounting matter.”

Some “dark accounting matter” is composed of factors commonly described as components of “ESG.” Human capital, for example, is an intangible asset …

Physical Therapy Faculty Publications

Background: Gait impairments are common in individuals with mild traumatic brain injury (mTBI), presenting in the acute phase and often persisting in subtle ways over time. Despite the prominence of laboratory gait evaluations, a comprehensive understanding of gait deficits post-mTBI necessitates the examination of various gait domains in real-world environments. Assessing gait during a community ambulation task (CAT) may capture real-world challenges and influence focused interventions or rehabilitation in individuals with mTBI.

Research Question: The aim of the study was to compare gait performance across independent gait domains in individuals with and without mTBI using wearable sensors during both the …

This qualitative study explores the virtual abstinence experience of distance learning human services students, using Mezirow’s transformative learning theory to examine how a 21-day experiential abstinence prompts critical reflection and perspective transformation. The study investigates the socio-emotional and physiological factors influencing participants' progress toward sobriety, including cravings, withdrawal, isolation, and relapse triggers. Findings highlight how participants' critical reflection leads to a deeper understanding of addiction and recovery, as well as an enhanced …


The Identity Factor, Jessica Feinberg Jan 2025

The Identity Factor, Jessica Feinberg

Faculty Publications

Identity development is one of the most important processes that occur during childhood. For certain populations of children, such as those who are LGBTQ+ or multiracial, the path to healthy identity development is substantially more complicated. These children must navigate the development of their identities while existing in a world in which they will frequently encounter a lack of societal understanding and acceptance. Children within these populations face elevated risks of short- and long-term harms, including suicidal ideation, depression, substance abuse, and low self-esteem. As a result, it is critically important that LGBTQ+ and multiracial youth receive support in developing …
