Racial Equality, Religious Liberty, And The Complications Of Pluralism, Rachel F. Moran

Faculty Scholarship

Constitutional law scholar Laurence Tribe once described due process and equal protection as “a legal double helix.” By this, he meant that protections for substantive liberties coupled with principles of equal treatment created “a single, unfolding tale of equal liberty and increasingly universal dignity.” In his view, equality and liberty were mutually constitutive and “center[ed] on a quest for genuine self-government of groups small and large.” Although this optimistic account of the nation’s constitutional DNA is reassuring, Professor Sahar Aziz’s new book on “The Racial Muslim: When Racism Quashes Religious Freedom” reminds us that the double helix can unravel, so …

Blockchain Real Estate And Nfts, Juliet M. Moringiello, Christopher K. Odinet

Faculty Scholarship

Non-fungible tokens (popularly known as NFTs) and blockchains are frequently promoted as the solution to a multitude of property ownership problems. The promise of an immutable blockchain is often touted as a mechanism to resolve disputes over intangible rights, notably intellectual property rights, and even to facilitate quicker and easier real estate transactions.

In this Symposium Article, we question the use of distributed ledger technologies as a method of facilitating and verifying the transfer of physical assets. As our example of an existing transfer method, we use real property law, which is characterized by centuries-old common law rules regarding fractionalized …

Machine Learning Techniques For Stock Price Prediction And Graphic Signal Recognition, Junde Chen, Yuxin Wen, Y. A. Nanehkaran, M. D. Suzauddola, Weirong Chen, Defu Zhang

Engineering Faculty Articles and Research

Stock market analysis is extremely important for investors because knowing the future trend and grasping the changing characteristics of stock prices will decrease the risk of investing capital for profit. Thereupon, the prediction of stock prices and identifying the graphic signals of candlestick charts, which are two crucial tasks in stock price analysis, attract much attention from investors owing to the returns and risks that coexist in financial markets. To introduce a reliable approach for addressing these challenges, this paper proposes the modeling strategies based on machine learning (ML) techniques. A vector autoregression (VAR)-based rolling prediction model is proposed for …

Epibionts Provide Their Basibionts With Associational Resistance To Predation But At A Cost, S Downes, L Firth, Am Knights

School of Biological and Marine Sciences

Epibiosis is increasingly considered a survival strategy in space-limited environments. However, epibionts can create a new interface between its host, environment and potential predators which may alter predator-prey relationships and biological functioning. Ex-situ experiments investigated the potential costs and benefits of epibiont barnacles on mortality and feeding rate of the mussel, Mytilus edulis, and its predator, the whelk Nucella lapillus. Mussels with living epibiont barnacles suffered no mortality from whelk predation, but when barnacles were absent, mortality was ~21% over 48 days. Further comparisons revealed the structural complexity of barnacles provided mussels with protection from whelk predation, while the presence …

The Superstition That Enslaves Virgin Girls In Ghana: An Exploration Of The Origins, Evolution, And Practice Of Trokosi, Emmanuel Sarpong Owusu

Dignity: A Journal of Analysis of Exploitation and Violence

Trokosi is a religious practice in some parts of West Africa where young virgin girls are sent to fetish shrines to become sex slaves as part of rituals meant to prevent a communal calamity supposedly provoked by the transgressions of members of the girls’ family. This study offers additional insight into the concept, origins, evolution, and practice of trokosi, highlighting the cultural, socio-economic, and legal contexts of this practice in Ghana. This goal is achieved by reviewing pertinent literature and interviewing 10 participants: academics; activists; traditional leaders; and ordinary community members. The study establishes that trokosi, which is …

Divided Yet One: The Two Catholic Communities In China, Gabriel Liu

Loyola Papers

This paper examines the commonly held perception that two Catholic Churches exist in China. Drawing from the perspective of a native Chinese Catholic, it argues that the reality is not the existence of two distinct Churches but rather two historically divided Catholic communities. The study traces the origins, development, and evolution of this division over the past decades, noting that the separation was not originally intended by ecclesial authorities and was later shaped by the policies of the Chinese communist government. While considering the broader social and political context of China, the paper primarily seeks to present a clearer public …

Wisdom: The Feminine In The Divine, Rogel Anecito L. Abais

Loyola Papers

This paper explores the figure of Lady Wisdom (sophia) in the Book of Wisdom, particularly her portrayal in Wisdom 7:22b–8:1. It examines whether Wisdom should be understood as a personification of God or as a divine attribute, highlighting the text’s rich imagery and theological depth. By tracing the development of the Wisdom figure in Scripture and engaging the feminist critique of Rosemary Radford Ruether, the study investigates how Wisdom literature presents feminine imagery within a largely androcentric biblical context. The analysis seeks to determine whether the depiction of Wisdom offers a meaningful affirmation of the feminine in the divine and …

Exploring Narratives Of Researcher Development For Student Researchers Abroad, Kirsten A. Davis, Teirra Holloman, Jessica Deters, David B. Knight

School of Engineering Education Faculty Publications

Background: Research experiences for undergraduate and graduate students have the potential to provide significant learning experiences, but most research of these experiences focuses primarily on their outcomes. To better design such experiences for a diverse range of students, it is important to understand student narratives of researcher development and identify significant experiences in their development as researchers.

Purpose: In this study, we explored narratives of researcher development for seven US civil engineering students in an eight-week research experience in Australia. Through these narratives, we sought to identify categories of significant experiences to characterize the early stage of the researcher development …

What Are Risk Factors For And Outcomes Of Late Amputation After Treatment For Lower Extremity Sarcoma: A Childhood Cancer Survivor Study Report, Erik J Geiger, Wei Liu, Deo Kumar Srivastava, Nicholas M Bernthal, Brent R Weil, Kirsten K Ness, Robert E Goldsby, Kevin C Oeffinger, Leslie L Robison, Bryan V Dieffenbach, Christopher B Weldon, Mark C Gebhardt, Rebecca Howell, Andrew J Murphy, Wendy M Leisenring, Gregory T Armstrong, Eric J Chow, Rosanna L Wustrack

Faculty, Staff and Student Publications

Background: Although pediatric lower extremity sarcoma once was routinely treated with amputation, multiagent chemotherapy as well as the evolution of tumor resection and reconstruction techniques have enabled the wide adoption of limb salvage surgery (LSS). Even though infection and tumor recurrence are established risk factors for early amputation (< 5 years) after LSS, the frequency of and factors associated with late amputation (≥ 5 years from diagnosis) in children with sarcomas are not known. Additionally, the resulting psychosocial and physical outcomes of these patients compared with those treated with primary amputation or LSS that was not complicated by subsequent amputation are not well studied. Studying these outcomes is critical to enhancing the quality of life of patients with sarcomas.

Questions/purposes: (1) How have treatments changed over time in patients with lower extremity sarcoma who are included in the Childhood Cancer Survivor Study (CCSS), and did primary treatment with amputation or LSS affect overall survival at 25 years among patients who had survived at least 5 years from diagnosis? (2) What …

Highly Synchronized Cortical Circuit Dynamics Mediate Spontaneous Pain In Mice, Weihua Ding, Lukas Fischer, Qian Chen, Ziyi Li, Liuyue Yang, Kun Hu, Xue Zhou, Wei Chao, Peter Hu, Tewodros Mulugeta Dagnew, Daniel M Dubreuil, Shiyu Wang, Suyun Xia, Caroline Bao, Shengmei Zhu, Lucy Chen, Changning Wang, Brian Wainger, Peng Jin, Jianren Mao, Guoping Feng, Mark T Harnett, Shiqian Shen

Cortical neural dynamics mediate information processing for the cerebral cortex, which is implicated in fundamental biological processes such as vision and olfaction, in addition to neurological and psychiatric diseases. Spontaneous pain is a key feature of human neuropathic pain. Whether spontaneous pain pushes the cortical network into an aberrant state and, if so, whether it can be brought back to a "normal" operating range to ameliorate pain are unknown. Using a clinically relevant mouse model of neuropathic pain with spontaneous pain-like behavior, we report that orofacial spontaneous pain activated a specific area within the primary somatosensory cortex (S1), displaying synchronized …

Summary of background data: Data are conflicting regarding pain outcomes and quality of life (QOL) among women who undergo different types of breast surgery.

Methods: Women with nonhereditary breast cancer completed the brief pain inventory before surgery and at 1, 6, 12, and 18 months postsurgery. We assessed associations between pain outcomes and CPM status and mastectomy status using multivariable repeated measures models. We assessed associations between pain outcome and …

Macrophage-Derived Mlkl In Alcohol-Associated Liver Disease: Regulation Of Phagocytosis, Xiaoqin Wu, Xiude Fan, Megan R Mcmullen, Tatsunori Miyata, Adam Kim, Jianguo Wu, Josiah E Hardesty, Nicole Welch, Jaividhya Dasarathy, Daniela S Allende, Arthur J Mccullough, Jon M Jacobs, Daniel M Rotroff, Srinivasan Dasarathy, Laura E Nagy

Faculty, Staff and Student Publications

BACKGROUND AND AIMS: Mixed lineage kinase domain-like pseudokinase (MLKL), a key terminal effector of necroptosis, also plays a role in intracellular vesicle trafficking that is critical for regulating liver inflammation and injury in alcohol-associated liver disease (ALD). Although receptor interacting protein kinase 3 (Rip3)-/- mice are completely protected from ethanol-induced liver injury, Mlkl-/- mice are only partially protected. Therefore, we hypothesized that cell-specific functions of MLKL may contribute to ethanol-induced injury.

APPROACH AND RESULTS: Bone marrow transplants between Mlkl-/- mice and littermates were conducted to distinguish the role of myeloid versus nonmyeloid Mlkl in the Gao-binge model of ALD. Ethanol-induced …

Dyadic Versus Individual Delivery Of A Yoga Program For Family Caregivers Of Glioma Patients Undergoing Radiotherapy: Results Of A 3-Arm Randomized Controlled Trial, Kathrin Milbury, Meagan Whisenant, Shiao-Pei Weathers, Smitha Malliaha, Stella Snyder, Jing Li, Roseanglea F Silva, Ya-Chen Tina Shih, Lorenzo Cohen

Faculty, Staff and Student Publications

BACKGROUND: Despite their significant distress, supportive care interventions for caregivers of glioma patients are generally lacking. And, whether caregivers are more likely to benefit from interventions targeting patient-caregiver dyads or caregivers individually is unknown. This pilot randomized controlled trial compared the feasibility and preliminary efficacy of a dyadic yoga (DY) versus an individual caregiver yoga (CY) intervention as a supportive care strategy for family caregivers.

METHODS: Patient-caregiver dyads were randomized to a DY, CY or usual care (UC) arm. DY and CY interventions were delivered over 15 sessions. Caregivers completed assessments of their depressive symptoms, quality of life (QOL), and …

Dysphagia And Shortness-Of-Breath As Markers For Treatment Failure And Survival In Oropharyngeal Cancer After Radiation, Jarey H Wang, Vivian Salama, Lance Mccoy, Cem Dede, Temitayo Ajayi, Abdallah S R Mohamed, Clifton David Fuller, Lisanne V Van Dijk, Md Anderson Head And Neck Symptom Working Group

Faculty, Staff and Student Publications

Background: Post-treatment symptoms are a focal point of follow-up visits for head and neck cancer patients. While symptoms such as dysphagia and shortness-of-breath early after treatment may motivate additional work up, their precise association with disease control and survival outcomes is not well established.

Methods: This prospective data cohort study of 470 oropharyngeal cancer patients analyzed patient-reported swallowing, choking and shortness-of-breath symptoms at 3-to-6 months following radiotherapy to evaluate their association with overall survival and disease control. Associations between the presence of moderate-to-severe swallowing, choking and mild-to-severe shortness-of-breath and treatment outcomes were analyzed via Cox regression and Kaplan-Meier. The main …

Immune-Checkpoint Inhibitor Therapy Response Evaluation Using Oncophysics-Based Mathematical Models, Mustafa Syed, Matthew Cagely, Prashant Dogra, Lauren Hollmer, Joseph D Butner, Eugene J Koay

Faculty, Staff and Student Publications

The field of oncology has transformed with the advent of immunotherapies. The standard of care for multiple cancers now includes novel drugs that target key checkpoints that function to modulate immune responses, enabling the patient's immune system to elicit an effective anti-tumor response. While these immune-based approaches can have dramatic effects in terms of significantly reducing tumor burden and prolonging survival for patients, the therapeutic approach remains active only in a minority of patients and is often not durable. Multiple biological investigations have identified key markers that predict response to the most common form of immunotherapy-immune checkpoint inhibitors (ICI). These …

On Target Methods To Induce Abscopal Phenomenon For Off-Target Effects: From Happenstance To Happenings, Blessie Elizabeth Nelson, Jacob J Adashek, Steven H Lin, Vivek Subbiah

Faculty, Staff and Student Publications

Although the "abscopal phenomenon" has been described several decades ago, this phenomenon lately has been obtaining momentous traction with the dawn of immune-based therapies. There has been increased cross talk among radiation oncologists, oncologists and immunologists and consequently a surge in the number of prospective clinical trials. This must be coupled with translation work from these clinical trials to aid in eventual identification of patients who may benefit. Abscopal effects may be induced by local and systemic methods, conventional radiotherapy, particle radiation, radionucleotide methods, cryoablation and brachytherapy. These approaches have all been reported to be stimulate abscopal effect. Immune induction …

A Biallelic Frameshift Indel In Ppp1r35 As A Cause Of Primary Microcephaly, Moez Dawood, Gulsen Akay, Tadahiro Mitani, Dana Marafi, Jawid M Fatih, Hossein Najmabadi, Jaya Punetha, Christopher M Grochowski, Haowei Du, Angad Jolly, He Li, Zeynep Coban-Akdemir, Fritz J Sedlazeck, Jill V Hunter, Shalini N Jhangiani, Donna Muzny, Davut Pehlivan, Jennifer E Posey, Claudia M B Carvalho, Richard A Gibbs, James R Lupski

Faculty, Staff and Student Publications

Protein phosphatase 1 regulatory subunit 35 (PPP1R35) encodes a centrosomal protein required for recruiting microtubule-binding elongation machinery. Several proteins in this centriole biogenesis pathway correspond to established primary microcephaly (MCPH) genes, and multiple model organism studies hypothesize PPP1R35 as a candidate MCPH gene. Here, using exome sequencing (ES) and family-based rare variant analyses, we report a homozygous, frameshifting indel deleting the canonical stop codon in the last exon of PPP1R35 [Chr7: c.753_*3delGGAAGCGTAGACCinsCG (p.Trp251Cysfs*22)]; the variant allele maps in a 3.7 Mb block of absence of heterozygosity (AOH) in a proband with severe MCPH (-4.3 SD at birth, -6.1 SD by …

Persistent Nociceptor Hyperactivity As A Painful Evolutionary Adaptation, Edgar T Walters, Robyn J Crook, G Gregory Neely, Theodore J Price, Ewan St John Smith

Faculty, Staff and Student Publications

Chronic pain caused by injury or disease of the nervous system (neuropathic pain) has been linked to persistent electrical hyperactivity of the sensory neurons (nociceptors) specialized to detect damaging stimuli and/or inflammation. This pain and hyperactivity are considered maladaptive because both can persist long after injured tissues have healed and inflammation has resolved. While the assumption of maladaptiveness is appropriate in many diseases, accumulating evidence from diverse species, including humans, challenges the assumption that neuropathic pain and persistent nociceptor hyperactivity are always maladaptive. We review studies indicating that persistent nociceptor hyperactivity has undergone evolutionary selection in widespread, albeit selected, animal …

Faculty, Staff and Student Publications

BACKGROUND AND PURPOSE: Newer technologies allow for daily treatment adaptation, providing the ability to account for setup variations and organ motion but comes at the cost of increasing the treatment workflow complexity. One such technology is the adapt-to-position (ATP) workflow on the Unity MR-Linac. Prospective risk assessment of a new workflow allows clinics to catch errors before they occur, especially for processes that include novel and unfamiliar steps.

METHODS: As part of a quality management program, failure modes and effects analysis was performed on the ATP treatment workflow following the recommendations of AAPM's Task Group 100. A multidisciplinary team was …

Dosimetric Response Of Gafchromic™ Ebt-Xd Film To Therapeutic Protons, Fada Guan, Xiaochun Wang, Ming Yang, Emily Draeger, Dae Han, Fanqing Guo, Yuting Li, Narayan Sahoo, Radhe Mohan, Zhe Chen

Faculty, Staff and Student Publications

The EBT-XD model of Gafchromic™ films has a broader optimal dynamic dose range, up to 40 Gy, compared with its predecessor models. This characteristic has made EBT-XD films suitable for high-dose applications, such as stereotactic body radiotherapy and stereotactic radiosurgery, as well as ultra-high dose rate FLASH radiotherapy. The purpose of the current study was to characterize the dependence of EBT-XD film response on linear energy transfer (LET) and dose rate of therapeutic protons from a synchrotron. A clinical spot-scanning proton beam was used to study LET dependence at three dose-averaged LET values of 1.0 keV/μm, 3.6 keV/μm, and 7.6 …
