Disabling Travel: Quantifying The Harm Of Inaccessible Hotels To Disabled People, Kristen L. Popham, Elizabeth F. Emens, Jasmine E. Harris Jan 2023

Disabling Travel: Quantifying The Harm Of Inaccessible Hotels To Disabled People, Kristen L. Popham, Elizabeth F. Emens, Jasmine E. Harris

Faculty Scholarship

During its 2023–2024 term, the U.S. Supreme Court will decide a case with significant implications for the future of the Americans with Disabilities Act (ADA). In Acheson Hotels v. Laufer, the Court will determine whether a civil rights “tester” plaintiff has Article III standing to sue a hotel for failing to provide information about the hotel’s accessibility online — in violation of Department of Justice (DOJ) regulations applying the ADA’s requirement of “reasonable modifications in policies, practices, or procedures” — when the plaintiff did not intend to book a hotel reservation. Plaintiff-Respondent Deborah Laufer has not only challenged the …


Affirmative Action After Sffa, Jonathan Feingold Jan 2023

Affirmative Action After Sffa, Jonathan Feingold

Faculty Scholarship

In SFFA v. Harvard (SFFA), the Supreme Court further restricted a university’s right to consider the racial identity of individual applicants during admissions. The ruling has spawned considerable confusion regarding a university’s ongoing ability to pursue racial diversity, racial inclusion, and other equality-oriented goals—whether through “raceconscious” or “race-neutral” means. To assist institutions attempting to navigate the ruling, this article outlines a set of key legal rights and responsibilities that universities continue to possess following SFFA.


Knowledge Generation And Uncertainty In An Unpredictable Social World, Benjamin David Pyle Jan 2023

Knowledge Generation And Uncertainty In An Unpredictable Social World, Benjamin David Pyle

Faculty Scholarship

Professor Megan T. Stevenson’s Article, Cause, Effect, and the Structure of the Social World, is an incredibly important, deep, and thought-provoking argument explaining what we can learn about fundamental causal relationships when we observe few interventions with long-lasting, cascading consequences.1 It is a profound reflection on empirical work in the social sciences.

The Article argues that we have found few, if any, well-identified policy levers that generate outsized, long-term positive impacts for those impacted by the criminal legal system. It offers several explanations for the lack of randomized control trial (“RCT”) evaluations with large, non-mechanical effects, but the …


Large Corporations And Investor-State Arbitration, Weijia Rao Jan 2023

Large Corporations And Investor-State Arbitration, Weijia Rao

Faculty Scholarship

Policymakers and scholars have expressed concerns about growing corporate influence over government regulations, including in the context of investor-state dispute settlement (“ISDS”). Encouraged by high profile victories and examples of “regulatory chill,” critics of ISDS have argued that it excessively serves large multinational corporate interests at the expense of government regulatory agendas. In part due to such criticisms, various proposals have been made, including the replacement of ISDS with multilateral investment courts or state-to-state arbitration.

This Article introduces a novel dataset on ISDS claimant characteristics, which reveals that most ISDS claimants are actually small- or medium-sized firms. Using this dataset, …


Remembering The Origins Of Modern Legal Education, Paula A. Monopoli Jan 2023

Remembering The Origins Of Modern Legal Education, Paula A. Monopoli

Faculty Scholarship

American legal education came under tremendous pressure in the wake of the 2008 financial crisis. That crisis precipitated a decline in law school applications and a concomitant decrease in the size of American law school enrollments during the 2011–2012 academic year. Commentators offered a myriad of proposals for reforming legal education during that period. Yet many of those proposals failed to gain traction, and a decade later legal education looks much the same, albeit with smaller enrollments. One of those proposals was to shorten the three-year course of study. In this Article, I revisit the origins of that long-standing feature …


Situating Dobbs, Paula A. Monopoli Jan 2023

Situating Dobbs, Paula A. Monopoli

Faculty Scholarship

The recent decision in Dobbs v. Jackson Women’s Health has been characterized as an outlier because its effect is to erase a previously recognized constitutional right. This paper situates Dobbs in a broader feminist constitutional history. It asks if this retrenchment is really such a unique turn in American jurisprudence when it comes to protections or “rights” that matter most to women’s lived experience. The paper argues that if one opens the aperture of constitutional history to embrace a more capacious view of rights, those afforded to women have often been eroded or erased by state legislatures, Congress, and courts. …

Use Of An Invertebrate Animal Model (Aplysia Californica) To Develop Novel Neural Interfaces For Neuromodulation, Junqi Zhuo, Jeffrey P. Gill, Michael W. Jenkins, Hillel J. Chiel

Faculty Scholarship

New tools for monitoring and manipulating neural activity have been developed with steadily improving functionality, specificity, and reliability, which are critical both for mapping neural circuits and treating neurological diseases. This review focuses on the use of an invertebrate animal, the marine mollusk Aplysia californica, in the development of novel neurotechniques. We review the basic physiological properties of Aplysia neurons and discuss the specific aspects that make it advantageous for developing novel neural interfaces: First, Aplysia nerves consist only of unmyelinated axons with various diameters, providing a particularly useful model of the unmyelinated C fibers in vertebrates that are known …

An Implementation Roadmap For Establishing Remote Infectious Disease Specialist Support For Consultation And Antibiotic Stewardship In Resource-Limited Settings, Robin L.P. Jump

Faculty Scholarship

Infectious Disease (ID)-trained specialists, defined as ID pharmacists and ID physicians, improve hospital care by providing consultations to patients with complicated infections and by leading programs that monitor and improve antibiotic prescribing. However, many hospitals and nursing homes lack access to ID specialists. Telehealth is an effective tool to deliver ID specialist expertise to resource-limited settings. Telehealth services are most useful when they are adapted to meet the needs and resources of the local setting. In this step-by-step guide, we describe how a tailored telehealth program can be implemented to provide remote ID specialist support for direct patient consultation and …


The Mediating Effect Of Caregiving Relationship Quality On The Association Between Caregiving Stressors And Mental Health Problems Among Older Spousal Caregivers, Fei Wang, Elliane Irani Dec 2022

The Mediating Effect Of Caregiving Relationship Quality On The Association Between Caregiving Stressors And Mental Health Problems Among Older Spousal Caregivers, Fei Wang, Elliane Irani

Faculty Scholarship

Providing care to a spouse can be especially challenging for older adults given their compounding stressors resulting from aging and caregiving. This cross-sectional study examines the relationships between caregiving stressors and caregiver mental health problems and the potential mediator (i.e., caregiving relationship quality) of these associations. A total of 431 Americans (≥65 years) were selected from the National Study of Caregiving. Path analysis shows that care assistance was positively associated with caregiver mental health problems, and this association was mediated by negative relationship quality (Indirect effect =.14, p =.016). Moreover, role overload was positively associated with caregiver mental health problems, …


Pum1 Mediates The Posttranscriptional Regulation Of Human Fetal Hemoglobin, Yuncheng Man, Amma Owusu-Ansah, Omar Y. Mian, Umut A. Gurkan, Anton A. Komar, Merlin Nithya Gnanapragasam Dec 2022

Pum1 Mediates The Posttranscriptional Regulation Of Human Fetal Hemoglobin, Yuncheng Man, Amma Owusu-Ansah, Omar Y. Mian, Umut A. Gurkan, Anton A. Komar, Merlin Nithya Gnanapragasam

Faculty Scholarship

The fetal-to-adult hemoglobin switching at about the time of birth involves a shift in expression from γ-globin to β-globin in erythroid cells. Effective re-expression of fetal γ-globin can ameliorate sickle cell anemia and β-thalassemia. Despite the physiological and clinical relevance of this switch, its posttranscriptional regulation is poorly understood. Here, we identify Pumilo 1 (PUM1), an RNA-binding protein with no previously reported functions in erythropoiesis, as a direct posttranscriptional regulator of β-globin switching. PUM1, whose expression is regulated by the erythroid master transcription factor erythroid Krüppel-like factor (EKLF/KLF1), peaks during erythroid differentiation, binds γ-globin messenger RNA (mRNA), and reduces γ-globin …

Socioeconomic Deprivation And Cardiometabolic Risk Factors In Individuals With Type 1 Diabetes: T1d Exchange Clinic Registry, Stephanie Griggs, Sadeer Al-Kindi, Heather Hardin, Elliane Irani, Sanjay Rajagopalan, Ronald L. Hickman Jr.

Faculty Scholarship

Aims: Social determinants of health (SDOH) influence cardiovascular health in the general population; however, the degree to which this occurs in individuals with type 1 diabetes (T1D) is not well understood. We evaluated associations among socioeconomic deprivation and cardiometabolic risk factors (hemoglobin A1c, low-density lipoprotein, blood pressure, body mass index, physical activity) in individuals with T1D from the T1D Clinic Exchange Registry. Methods: We evaluated the association between the social deprivation index (SDI) and cardiometabolic risk factors using multivariable and logistic regression among 18,754 participants ages 13 – 90 years (mean 29.2 ± 17) in the T1D Exchange clinic registry …


Moral Status And The Oversight Of Research Involving Chimeric Animals, Patricia Marshall, Kaitlynn P. Craig Dec 2022

Moral Status And The Oversight Of Research Involving Chimeric Animals, Patricia Marshall, Kaitlynn P. Craig

Faculty Scholarship

The use of nonhuman animals in research has long been a source of bioethical and scientific debate. We consider the oversight and use of nonhuman animals in chimeric research. We conducted interviews with twelve members of embryonic stem cell research oversight committees, nine members of institutional animal care and use committees, and fourteen scientists involved in human–nonhuman-animal chimeric research in different areas of the United States. Interviews addressed animal welfare and conceptual issues associated with moral status and humanization of nonhuman animals that contain human cells. Our findings suggest that concepts of enhanced moral status and consciousness are not very …


Fostering Durable Skills Development: Leveraging Student Worker Programs, James Hutson, Elizabeth Macdonald, Lisa Young, Susan Edele, Chris Smentkowski Dec 2022

Fostering Durable Skills Development: Leveraging Student Worker Programs, James Hutson, Elizabeth Macdonald, Lisa Young, Susan Edele, Chris Smentkowski

Faculty Scholarship

The past half century has witnessed exponential increases in the cost of a college degree paralleled by an increase of undergraduate students who are employed during matriculation. While the impact on learning outcomes due to off-campus employment continues to receive much attention, there has been little attention paid to students employed on-campus through student worker programs and their benefits, especially in developing durable skills and improving retention. Research has demonstrated that engagement in oncampus activities improves retention and persistence in students. Additionally, employers desire power or durable skills (formerly known as “soft skills”), and that student worker programs are suited …

Novel Screening Tool And Considerations For Music Therapists Serving Autistic Individuals Via Telehealth: Qualitative Results From A Survey Of Clinicians’ Experiences, Nicole M. Richard Williams

Faculty Scholarship

During the COVID-19 pandemic, music therapists transitioned services from in-person to telehealth due to health and safety concerns. Though online delivery of music therapy services for autistic individuals occurred prior to 2020, the number of North American music therapists using telehealth with autistic clients rose substantially during the pandemic. The current paper’s objective was to delineate music therapists’ perceptions regarding factors that helped or hindered autistic persons’ engagement in online music therapy sessions. One-hundred ninety-two participants completed the survey. Qualitative content analysis of an open-ended question identified seven overarching themes regarding benefits and challenges of telehealth music therapy for autistic …

Open Educational Resources And Institutional Repositories: Roles, Challenges, And Opportunities For Libraries, James Hutson, Susan Edele, Elizabeth Macdonald, Paul Huffman, Nancy Messina, Maggie Pavone, Carla Mueller, Gabriela Romero

Faculty Scholarship

The adoption of digital-born, Open Educational Resources (OER) has been proven to improve student retention and learning outcomes, and OER has the flexibly to support multiple modalities of instruction. Institutional Repositories are uniquely situated to act as a platform to support and distribute content that can be created collaboratively between faculty researchers as well as students. However, faculty are still largely hesitant to adopt OER sources for a variety of reasons, not least among them being a lack of exposure and understanding of the potential benefits for both faculty and students in keeping curriculum affordable, up-to-date, and nimble through media-rich, …


Essential Property, Timothy M. Mulvaney, Joseph William Singer Dec 2022

Essential Property, Timothy M. Mulvaney, Joseph William Singer

Faculty Scholarship

For a sizable swath of the U.S. population, incomes and wealth are insufficient to cover life’s most basic necessities even in the most ordinary of times. A disturbingly resilient explanation for this state of affairs rests on the view that resource inequities are avoidable through self-reliance, a stance that invites observers to see people in poverty as morally suspect. This Article advances a counterview in contending that the widespread lack of essential resources did not simply arise naturally via individuals’ life choices but instead has been, in very meaningful part, created and perpetuated by our system of property laws.

The …


Designing For Justice: Pandemic Lessons For Criminal Courts, Cynthia Alkon Dec 2022

Designing For Justice: Pandemic Lessons For Criminal Courts, Cynthia Alkon

Faculty Scholarship

March 2020 brought an unprecedented crisis to the United States: COVID-19. In a two-week period, criminal courts across the country closed. But, that is where the uniformity ended. Criminal courts did not have a clear process to decide how to conduct necessary business. As a result, criminal courts across the country took different approaches to deciding how to continue necessary operations and in doing so many did not consider the impact on justice of the operational changes that were made to manage the COVID-19 crisis. One key problem was that many courts did not use inclusive processes and include all …

This study assessed correlates of disaster preparedness among community-dwelling minority older adults and explored unique differences for African American and Hispanic older adults. An electronic survey was disseminated to older minority adults 55+, between November 2020 and January 2021 (n = 522). An empirical framework was used to contextualize 12 disaster-related activities into survival and planning actions. Multivariate logistic regression models were stratified by race/ethnicity to examine the …


The Role Of Virtual Reality In Art Therapy To Mitigate Autism Spectrum Disorder (Asd) Symptoms, James Hutson Dec 2022

The Role Of Virtual Reality In Art Therapy To Mitigate Autism Spectrum Disorder (Asd) Symptoms, James Hutson

Faculty Scholarship

Traditional art therapy sessions are designed for face-to-face engagement with patients as with other mental health services such as counseling. However, the pandemic of 2019 severely limited access to these services and, initially, led to widespread cancelation and postponement until the nature of COVID-19 could be better understood. When treatment resumed, video conferencing was the preferred method of holding therapy sessions one-on-one to diagnose patients and provide services. Similar approaches were taken in art therapy with less efficacy given the hands-on nature of the required activities. With the rise of virtual reality (VR) as a more widely accessible technology since …


Would You Make It To The Future? Teaching Race In An Assisted Reproductive Technologies And The Law Classroom, Sonia Gipson Rankin Dec 2022

Would You Make It To The Future? Teaching Race In An Assisted Reproductive Technologies And The Law Classroom, Sonia Gipson Rankin

Faculty Scholarship

Would you make it to the future? For the last five years, I have started my Assisted Reproductive Technology (ART) lecture in Family Law with this question. Students take the query seriously. They ponder their lived experiences such as home training, medical history, education, financial well-being, personality traits, work ethic, and social graces when determining if they would be the “model DNA” someone might select in a future society. The good-natured jokes about being nearsighted, having a pitiful jump shot, and wearing orthodontic headgear turn reflective when someone raises the question: would someone in the future select my race? In …

Multispectral Imaging For Microchip Electrophoresis Enables Point-Of-Care Newborn Hemoglobin Variant Screening, Ran An, Yuning Huang, Anne Rocheleau, Qiaochu Zhang, Yuncheng Man, Zoe Sekyonda, Amma Owusu-Ansah, Umut A. Gurkan

Faculty Scholarship

Hemoglobin (Hb) disorders affect nearly 7% of the world's population. Globally, around 400,000 babies are born annually with sickle cell disease (SCD), primarily in sub-Saharan Africa where morbidity and mortality rates are high. Screening, early diagnosis, and monitoring are not widely accessible due to technical challenges and cost. We hypothesized that multispectral imaging will allow sensitive hemoglobin variant identification in existing affordable paper-based Hb electrophoresis. To test this hypothesis, we developed the first integrated point-of-care multispectral Hb variant test: Gazelle-Multispectral. Here, we evaluated the accuracy of Gazelle-Multispectral for Hb variant newborn screening in 265 newborns with known hemoglobin variants including …


"Keep To The Code”: A Global Code Of Conduct For Third-Party Funders, Victoria Sahani Dec 2022

"Keep To The Code”: A Global Code Of Conduct For Third-Party Funders, Victoria Sahani

Faculty Scholarship

Global commercial third-party funding has given rise to wide-ranging regulatory approaches worldwide. Consequently, funders can engage in cross-border regulatory arbitrage by exploiting regulatory gaps within and among nations. This Article argues that the global community of nations should articulate a universal approach to the behavioral expectations of third-party funders operating transnationally, independent of local laws regarding the technical business of funding. It asserts that the key to fostering the ethical development of the third-party funding industry is to develop a globally applicable but locally enforced code of conduct or professional responsibility for the industry. Moreover, a successful regime for funder …


Why Money Is Well Spent On Time, Michael Ulrich Dec 2022

Why Money Is Well Spent On Time, Michael Ulrich

Faculty Scholarship

There are a few reasons why incentivizing clinicians to spend more time with patients can improve health outcomes. Doing so affords clinicians time to assess social determinants’ influences on their patients’ health experiences; offers opportunities to identify and respond to patients’ loneliness; and helps motivate patients’ trust in health care, strengthen patient-clinician relationships, and bolster patients’ adherence to clinicians’ recommendations.

Comments Of The Cordell Institute For Policy In Medicine & Law At Washington University In St. Louis, Neil Richards, Woodrow Hartzog, Jordan Francis

Faculty Scholarship

The Federal Trade Commission—with its broad, independent grant of authority and statutory mandate to identify and prevent unfair and deceptive trade practices—is uniquely situated to prevent and remedy unfair and deceptive data privacy and data security practices. In an increasingly digitized world, data collection, processing, and transfer have become integral to market interactions. Our personal and commercial experiences are now mediated by powerful, information-intensive firms who hold the power to shape what consumers see, how they interact, which options are available to them, and how they make decisions. That power imbalance exposes consumers and leaves them all vulnerable. We all …


Social Determinants Of Health And Child Maltreatment Prevention: The Family Success Network Pilot, Nancy Rolock, David Crampton Nov 2022

Social Determinants Of Health And Child Maltreatment Prevention: The Family Success Network Pilot, Nancy Rolock, David Crampton

Faculty Scholarship

Child maltreatment is a highly prevalent public health concern that contributes to morbidity and mortality in childhood and short- and long-term health consequences that persist into adulthood. Past research suggests that social determinants of health such as socioeconomic status and intergenerational trauma are highly correlated with child maltreatment. With support from the U.S. Children’s Bureau, the Ohio Children’s Trust Fund is currently piloting the Family Success Network, a primary child maltreatment prevention strategy in Northeast Ohio that seeks to address these social determinants through pillars of service that include family coaching, financial assistance, financial education, parenting education, and basic life …

Catch Bonds In Sickle Cell Disease: Shear-Enhanced Adhesion Of Red Blood Cells To Laminin, Utku Goreke, Shamreen Iram, Gundeep Singh, Sergio Domínguez-Medina, Yuncheng Man, Allison Bode, Ran An, Jane A. Little, Christopher L. Wirth, Michael Hinczewski, Umut A. Gurkan

Faculty Scholarship

Could the phenomenon of catch bonding—force-strengthened cellular adhesion—play a role in sickle cell disease, where abnormal red blood cell (RBC) adhesion obstructs blood flow? Here we investigate the dynamics of sickle RBCs adhering to a surface functionalized with the protein laminin (a component of the extracellular matrix around blood vessels) under physiologically relevant micro-scale flow. First, using total internal reflectance microscopy we characterize the spatial fluctuations of the RBC membrane above the laminin surface before detachment. The complex dynamics we observe suggest the possibility of catch bonding, where the mean detachment time of the cell from the surface initially increases …
