"They Gave Me One Star?" An Analysis Of Online Reviews Of Hand Surgeons, Stephen J Demartini, Brendan J Navarro, Christopher J Dy

2020-Current year OA Pubs

PURPOSE: Measures of patient satisfaction are growing in importance. Patients can use online review websites as opportunities to both praise and criticize their physicians and health care experience. We examined "one star" reviews of American Society for Surgery of the Hand (ASSH) members, with the hypothesis that the types of complaints would differ based on patient management and physician gender (based on social identity).

METHODS: We assembled a list of ASSH members in the Midwest region using the ASSH "Find a Hand Surgeon" tool. We then screened three online physician rating websites, including Yelp.com, Healthgrades.com, and Vitals.com, for physician profiles …

Empirically Exploring The Physical Realizability Of Adversarial Examples, Ruoyao Wen

McKelvey School of Engineering Graduate Student Theses & Dissertations

The development of autonomous vehicles (AVs) has been accelerated by advancements in deep neural networks (DNNs), which power the complex perception systems necessary for safe and efficient real-world navigation. However, as AVs increasingly integrate into public transportation networks, the robustness of their perception systems against potential vulnerabilities is critical. Among these threats, adversarial attacks—particularly through the use of adversarial patches—pose significant risks. These patches are carefully crafted perturbations designed to mislead DNNs, potentially compromising AV safety by causing incorrect object recognition or misclassification.

While extensive research has demonstrated high attack success rates for adversarial patches in controlled digital environments, their …

Compartmental Disaggregation: Bridging Simulation And Sampling Methods For Synthetic Population Data Generation, Dylan Mack

McKelvey School of Engineering Graduate Student Theses & Dissertations

As agent-based models (ABMs) grow increasingly widespread in public health, their associated challenges have become all the more significant. Lauded for their ability to capture population heterogeneity, nonlinear dynamics, and emergent behaviors, disease ABMs are also computationally expensive and often require detailed inputs that describe each agent at the individual-level, known as synthetic population data. Current approaches for synthetic population data generation generally fall into one of two categories: sampling or simulation. These methods are both feasible only under restricted conditions and suffer from challenges surrounding data availability and computing power. This thesis proposes compartmental disaggregation, an intermediate method for …

Predicting Which Genes Will Respond To Transcription Factor Perturbation, Eric L. Jia

McKelvey School of Engineering Graduate Student Theses & Dissertations

A fundamental issue in mapping regulatory networks between transcription factors and their target genes is the poor overlap between the set of genes bound by a given transcription factor (TF), and the set of genes that are differentially expressed after knocking out or overexpressing the same TF. We began with the hypothesis that to predict whether a gene will respond to perturbation of a TF, it is important to not only consider whether that TF is bound at the gene’s promoter, but also whether other TFs bind at the same promoter.

In this work, we propose a novel modeling procedure …

Perianal Fistulizing Crohn's Disease-Associated Anorectal And Fistula Cancers: Systematic Review And Expert Consensus, Serre-Yu Wong, Parakkal Deepak, David H Ballard, Et Al.

2020-Current year OA Pubs

BACKGROUND & AIMS: Perianal fistulizing Crohn's disease (PFCD)-associated anorectal and fistula cancers are rare but often devastating diagnoses. However, given the low incidence and consequent lack of data and clinical trials in the field, there is little to no guidance on screening and management of these cancers. To inform clinical practice, we developed consensus guidelines on PFCD-associated anorectal and fistula cancers by multidisciplinary experts from the international TOpClass consortium.

METHODS: We conducted a systematic review by standard methodology, using the Newcastle-Ottawa Scale quality assessment tool. We subsequently developed consensus statements using a Delphi consensus approach.

RESULTS: Of 561 articles identified, …

A Heuristic Approach To Portrait Segmentation And Its Application To Synthetic Bokeh Generation, Charles J. Snead

Master's Theses

Segmentation of portrait images is an important technique used to separate the foreground and background of an image. This separation of layers is useful for selectively applying post-processing techniques to enhance the quality of the image, such as blurring the background. Automatic portrait segmentation is a complex process that can be completed with a high degree of accuracy using deep learning with neural networks, but training and inference are often very computationally expensive. This thesis aims to take a heuristic approach to portrait segmentation by combining classical image processing and computer vision techniques into a solution that can be run …

Enhanced Post-Capture Automatic White Balance For Srgb Images, Eric Huang

Master's Theses

Automatic white balancing (AWB) aims to correct color casts caused by varying illumination conditions, typically assuming access to RAW sensor data. However, many real-world applications involve only sRGB images that have already been processed by in-camera pipelines. In these cases, traditional AWB algorithms often underperform due to the nonlinear transformations done by these pipelines.

This thesis builds upon a data-driven color correction framework introduced by Afifi et al. that relies on RGB-UV histograms and learned color transforms. A revised automatic white balancing (AWB) framework that improves both color accuracy and runtime efficiency is proposed. A fallback routine is implemented to …

Constraining The Family Regulation System: The Contribution Of The Restatement Of The Law, Children And The Law, Clare Huntington

Faculty Scholarship

Advocates, policymakers, and scholars have argued for years that the family regulation system (also known as the child welfare system) fails families. Critics rightly note that the system does far too little to support families proactively and does not address the poverty and structural racism underlying many allegations of child abuse and neglect. The overrepresentation of Black, Native American, and Native Alaskan children in foster care is a stark and disturbing manifestation of these failings.

In response to these concerns, there is an active debate about abolishing or radically reforming the family regulation system to direct government funding to proactive …

Administrative Law And The Pandemic, Gillian E. Metzger

Faculty Scholarship

American administrative law’s relationship to change is, as they say, compli­cated. On the one hand, continual evolution has been an endemic feature of American administrative law. Doctrines such as Chevron deference to agency statutory interpretations were born, grew, and declined in just the period from the 1980s to today. On the other, the United States (US) Supreme Court regularly rejects such common law development in administrative law as illegitimate and insists that federal judges must adhere to the original terms of the 1946 Administrative Procedure Act (APA) and other statutes, unless the Constitution requires otherwise. And to this day scholars …

The 100-Year Life And The New Family Law, Naomi Cahn, Clare Huntington, Elizabeth S. Scott

Faculty Scholarship

This chapter reflects on the future of family law in an era of longer lives. Our analysis leads us to conclude that the 100-year life is indeed likely to have an impact on the nature, scope, and definition of family law, but that families will continue to function as the primary setting for intimacy and for caregiving and caretaking, whatever form those families take. Further, the importance to both individual and social welfare of family support throughout life points to a need for reform of current family law doctrine. The impact of longer life on doctrines regulating the relationship of …

Trump Attacks On Climate Science May Violate Numerous Federal Laws, Michael B. Gerrard

Faculty Scholarship

Starting on its first day on January 20, 2025, the second Trump administration has launched an unprecedented rollback of efforts to fight climate change. The Sabin Center for Climate Change Law’s Climate Backtracker already has 117 items.

Much of this is aimed at scientific research on climate change, or has the effect of inhibiting the conduct and dissemination of this research. Many of these actions may also violate federal laws.

This article discusses these actions, some of their legal implications, and the litigation challenges that have already been brought. It begins with actions that are specifically aimed at climate research, …

Toward A Dynamic View Of Corporate Purpose, Dorothy S. Lund

Faculty Scholarship

Scholars debating the corporation’s role in society generally advance the view that there is only one desirable orientation for corporations and their management. Specifically, proponents of a stakeholder governance model contend that focusing management on a broad set of corporate constituents maximizes overall welfare, while advocates of a shareholder-centric directive counter that prioritizing shareholders creates social welfare by rendering the firm most profitable. This Article offers another view: It suggests that the welfare-maximizing purpose for corporations could change depending on external economic conditions, which both of these positions assume away. Specifically, shareholder primacy is likely to promote welfare in a …

The Sec, Fraud, And Cryptocurrencies, Lawrence J. Trautman, Brian Elzweig, Neal F. Newman

Faculty Scholarship

The SEC’s Strategic Plan for Fiscal Years 2022–2026 is focused on the impact of the rapidly developing rate of change in new technologies that provide for markets to be more interconnected and interdependent than ever. Because Congress has yet to give the SEC, or any other agency, express authority to regulate cryptocurrency, the SEC has taken a regulation-by-enforcement approach. The SEC’s recent enforcement efforts relating to crypto asset securities were substantial, with enforcement actions addressing a range of alleged misconduct in the crypto asset securities space, including billion- dollar crypto fraud schemes; unregistered crypto asset offerings, platforms, and intermediaries; and …
