Innovating With In-Service Mathematics Teachers’ Professional Development: The Intersection Among Mixed-Reality Simulations, Approximation-Of-Practice, And Technology-Acceptance, Jair J. Aguilar, Seokmin Kang

Teaching and Learning Faculty Publications

In-service teachers must be provided with high-quality professional development (PD) opportunities that not only effectively improves and develops their skills, but also engage, and motivate them to continue growing. In this project, we studied in-service teachers’ perceptions, opinions, and mindset toward the use of mixed-reality simulations (MRS) as a potential tool for PD to advance and enhance their pedagogical knowledge for mathematics. We followed a convergent parallel mixed-method approach with 49 in-service teachers who were exposed to a series of simulations sessions. We found evidence that the use and integration of technologies like MRS as a tool for PD is …

Privately-Owned Versus Shared Automated Vehicle: The Roles Of Utilitarian And Hedonic Beliefs, Fatemeh Nazari, Yellitza Soto, Mohamadhossein Noruzoliaee

Civil Engineering Faculty Publications

Transportation systems will be likely transformed by the emergence of automated vehicles (AVs) promising for safe, convenient, and efficient mobility, especially if used in shared systems (shared AV or SAV). However, the potential tendency is observed towards owning AV as a private asset rather than using SAV. This calls for a research on investigating individuals’ attitude towards AV in comparison with SAV to recognize the barriers to the public’s tendency towards SAV. To do so, the present study proposes a modeling framework based on the theories in behavioral psychology to explain individuals’ preference for owning AV over using SAV, built …

Assessing An Online Patient Decision Aid About Upper Extremity Reconstructive Surgery For Cervical Spinal Cord Injury: Pilot Testing Knowledge, Decisional Conflict, And Acceptability, William Moritz, Amanda M Westman, Mary C Politi, Dod Working Group, Ida K Fox

2020-Current year OA Pubs

UNLABELLED:

HIGHLIGHTS: People with cervical spinal cord injury prioritize gaining upper extremity function after injury, but few individuals receive information about treatment options.A newly created patient decision aid (PtDA) provides information about recovery after spinal cord injury and the role of traditional tendon and newer nerve transfer surgery to improve upper extremity upper extremity function.The PtDA improved knowledge and decreased decisional conflict in this pilot study.Future work should focus on studying dissemination and implementation of the ptDA into clinical practice.

Microbiome-Targeting Therapies In The Neonatal Intensive Care Unit: Safety And Efficacy, Anna Deveaux, Jian Ryou, Gautam Dantas, Barbara B Warner, Phillip I Tarr

2020-Current year OA Pubs

Microbiome-targeting therapies have received great attention as approaches to prevent disease in infants born preterm, but their safety and efficacy remain uncertain. Here we summarize the existing literature, focusing on recent meta-analyses and systematic reviews that evaluate the performance of probiotics, prebiotics, and/or synbiotics in clinical trials and studies, emphasizing interventions for which the primary or secondary outcomes were prevention of necrotizing enterocolitis, late-onset sepsis, feeding intolerance, and/or reduction in hospitalization length or all-cause mortality. Current evidence suggests that probiotics and prebiotics are largely safe but conclusions regarding their effectiveness in the neonatal intensive care unit have been mixed. To …

Cognition And Education Benefits Of Increased Hemoglobin And Blood Oxygenation In Children With Sickle Cell Disease, Joanna P. Macewan, Allison A. King, Andy Nguyen, Anuj Mubayi, Irene Agodoa, Kim Smith-Whitley

2020-Current year OA Pubs

BACKGROUND: Among individuals with sickle cell disease (SCD), decreased hemoglobin is associated with lower oxygen saturation (SpO2) and increased risk of stroke, both of which are associated with lower intelligence quotient (IQ) scores. Thus, increasing hemoglobin and SpO2 in individuals with SCD may increase IQ and educational attainment.

METHODS: A cohort simulation model was built to determine academic performance and educational attainment based on cognitive function (measured by IQ) of a pediatric SCD cohort randomly assigned to treatment and control groups. The model contained two key stages: childhood (<10 years) and adolescence (≥10 years). In stage 1, increased hemoglobin and increased SpO2 (assigned to the treatment group) were determinants of higher IQ, prevention of IQ deterioration over time. Increased hemoglobin was also a determinant of decreased stroke risk. In stage 2, improvement in adolescent IQ as a result of treatment was a determinant of academic performance.

RESULTS: In a simulated cohort of 2000 children and adolescents with …

A Single-Molecule Method For Measuring Fluorophore Labeling Yields For The Study Of Membrane Protein Oligomerization In Membranes, Melanie Ernst, Tugba N. Ozturk, Janice L. Robertson

2020-Current year OA Pubs

Membrane proteins are often observed as higher-order oligomers, and in some cases in multiple stoichiometric forms, raising the question of whether dynamic oligomerization can be linked to modulation of function. To better understand this potential regulatory mechanism, there is an ongoing effort to quantify equilibrium reactions of membrane protein oligomerization directly in membranes. Single-molecule photobleaching analysis is particularly useful for this as it provides a binary readout of fluorophores attached to protein subunits at dilute conditions. However, any quantification of stoichiometry also critically requires knowing the probability that a subunit is fluorescently labeled. Since labeling uncertainty is often unavoidable, we …

2020-Current year OA Pubs

PURPOSE: There is an unmet need to identify women diagnosed with ductal carcinoma in situ (DCIS) with a low risk of in-breast recurrence (IBR) after breast conserving surgery (BCS), which could omit radiation therapy (RT), and also to identify those with elevated IBR risk remaining after BCS plus RT. We evaluated a novel biosignature for a residual risk subtype (RRt) to help identify patients with elevated IBR risk after BCS plus RT.

METHODS AND MATERIALS: Women with DCIS treated with BCS with or without RT at centers in the US, Australia, and Sweden (n = 926) were evaluated. Patients were …

Sting Suppresses Mitochondrial Vdac2 To Govern Rcc Growth Independent Of Innate Immunity, Zhichuan Zhu, Xin Zhou, Hongwei Du, Erica W Cloer, Jiaming Zhang, Liu Mei, Ying Wang, Xianming Tan, Austin J Hepperla, Jeremy M Simon, Jeanette Gowen Cook, Michael B Major, Gianpietro Dotti, Pengda Liu

2020-Current year OA Pubs

STING is an innate immune sensor for immune surveillance of viral/bacterial infection and maintenance of an immune-friendly microenvironment to prevent tumorigenesis. However, if and how STING exerts innate immunity-independent function remains elusive. Here, the authors report that STING expression is increased in renal cell carcinoma (RCC) patients and governs tumor growth through non-canonical innate immune signaling involving mitochondrial ROS maintenance and calcium homeostasis. Mitochondrial voltage-dependent anion channel VDAC2 is identified as a new STING binding partner. STING depletion potentiates VDAC2/GRP75-mediated MERC (mitochondria-ER contact) formation to increase mitochondrial ROS/calcium levels, impairs mitochondria function, and suppresses mTORC1/S6K signaling leading to RCC growth …

Faculty and Staff Publications

In the spring of 2020, the COVID-19 pandemic rapidly brought college baseball to a halt. Most college baseball players saw disruption of their training and development due to interruptions of their seasons. With these interruptions, it is necessary to examine the effects of the COVID-19 pandemic on collegiate baseball injury epidemiology. Data from a small-school Midwest collegiate conference was tallied for the number of collegiate conference injuries per year, and for the injuries per anatomic region. An unpaired t-test was conducted upon the overall conference mean injuries per year and on each anatomic region for the mean injuries per region …

Transient Rise In Medical Abortions At Michigan Clinic During Sars-Cov-2 “Stay-At-Home” Order, Rachel Steffes, Susanna Wang, Jennifer F. Dennis

Faculty and Staff Publications

Background

In response to the SARS-CoV-2 (COVID-19) pandemic, the State of Michigan enacted a “stay-at-home” executive order detailing social distancing guidelines on March 24, 2020, with an expiration date of June 1, 2020.

Objectives

Given that medical abortions allow for pregnancy tissue to be passed in the privacy of one’s home, the authors hypothesized that there would be an increase in medical abortions over first trimester surgical abortions in 2020 compared to 2019 due to social distancing guidelines.

Study Design

Retrospective data was collected from an abortion clinic in Southeastern Michigan between January 1, 2019 and December 31, 2020 (n=4,703). …

Aromatic Amino Acid Metabolites Alter Interferon Signaling And Influenza Pathogenesis, Gautam Anand, Colin Clark-Dinovo, Alexandra M Perry, Victoria M Goodwin, Emma St Raymond, Sonia Sakleshpur, Ashley L Steed

2020-Current year OA Pubs

The ability of gut microbial metabolites to influence the host is increasingly recognized. The microbiota extensively metabolizes the three aromatic amino acids, tryptophan, tyrosine, and phenylalanine. Previously we have found that a metabolite of tyrosine, 4-OH-phenylpropionic acid, can enhance type I interferon (IFN) signaling and protect from influenza pathogenesis in a murine model. Herein we screened 17 related aromatic amino acid metabolites for effects on IFN signaling in human lung epithelial cells and monocytes alone and in the presence of IFN-β, influenza, and LPS. While the tryptophan family metabolites reduced IFN signaling in both cell types, the tyrosine and phenylalanine …

2020-Current year OA Pubs

INTRODUCTION: The availability of a human-like chronic heart failure (HF) animal model was critical for affiliating development of novel therapeutic drug treatments. With the close physiology relatedness to humans, the non-human primate (NHP) HF model would be valuable to better understand the pathophysiology and pharmacology of HF. The purpose of this work was to present preliminary cardiac image findings using echocardiography and cardiovascular magnetic resonance (CMR) in a HF-like cynomolgus macaque model.

METHODS: The NHP diet-induced model developed cardiac phenotypes that exhibited diastolic dysfunction with reduced left ventricular ejection fraction (LVEF) or preserved LVEF. Twenty cynomolgus monkeys with cardiac dysfunction …

Open-Source Statistical And Data Processing Tools For Wide-Field Optical Imaging Data In Mice, Lindsey M. Brier, Joseph P. Culver

2020-Current year OA Pubs

SIGNIFICANCE: Wide-field optical imaging (WOI) can produce concurrent hemodynamic and cell-specific calcium recordings across the entire cerebral cortex in animal models. There have been multiple studies using WOI to image mouse models with various environmental or genetic manipulations to understand various diseases. Despite the utility of pursuing mouse WOI alongside human functional magnetic resonance imaging (fMRI), and the multitude of analysis toolboxes in the fMRI literature, there is not an available open-source, user-friendly data processing and statistical analysis toolbox for WOI data.

AIM: To assemble a MATLAB toolbox for processing WOI data, as described and adapted to combine techniques from …

Time Off Work For Menstruation: A Good Idea?, Deborah Widiss

Articles by Maurer Faculty

In February 2023, Spain became the first European country to guarantee “menstrual leave” for workers, joining several countries, mostly in East Asia, that have long done so. It has also become increasingly common for companies to offer paid time off to menstruators as a discretionary benefit. Reports on these developments are almost always accompanied by criticism from self-identified feminists voicing concern that the policies will spur discrimination against women or reinforce stereotypes about menstruators as incapable workers. This echoes earlier arguments over maternity leave. In their groundbreaking book, Menstruation Matters, Bridget Crawford and Emily Waldman expose myriad ways in which …

Accessing Justice With Zoom: Experiences And Outcomes In Online Civil Courts, Victor D. Quintanilla, Kurt Hugenberg, Ryan Hutchings, Nedim Yel

Articles by Maurer Faculty

The global COVID-19 pandemic brought significant change to our civil justice system, particularly in the rapid shift from in-person to remote court proceedings. Courts across the country, facing the unprecedented challenge of a global health emergency, embraced rapid innovation and the adoption of remote proceeding platforms, such as Zoom and Webex. State courts did so across case types, including within high-volume civil dockets containing evictions, debt collections, small claims, and family law cases, where millions of self-represented and unrepresented litigants encounter the U.S. civil justice system each year. Amid the pandemic, voices converged to encourage these justice innovations, including the …

The Child Vanishes: Justice Scalia's Approach To The Role Of Psychology In Determining Children's Rights And Responsibilities, Aviva Orenstein

Articles by Maurer Faculty

This Article explores how Justice Antonin Scalia’s hostility to psychology, antipathy to granting children autonomous rights, and dismissiveness of children’s interior lives both affected his jurisprudence and was a natural outgrowth of it. Justice Scalia expressed a skeptical, one might even say hostile, attitude towards psychology and its practitioners. Justice Scalia’s cynicism about the discipline and the therapists who practice it is particularly interesting regarding legal and policy arguments concerning children. His love of tradition and his rigid and unempathetic approach to children clash with modern notions of child psychology. Justice Scalia’s attitude towards psychology helps to explain his jurisprudence, …

On Fires, Floods, And Federalism, Andrew Hammond

Articles by Maurer Faculty

In the United States, law condemns poor people to their fates in states. Where Americans live continues to dictate whether they can access cash, food, and medical assistance. What’s more, immigrants, territorial residents, and tribal members encounter deteriorated corners of the American welfare state. Nonetheless, despite repeated retrenchment efforts, this patchwork of programs has proven remarkably resilient. Yet, the ability of the United States to meet its people’s most basic needs now faces an unprecedented challenge: climate change. As extreme weather events like wildfires and hurricanes become more frequent and more intense, these climate-fueled disasters will displace and impoverish more …

How The Supreme Court Ghosted The Phosita: Amgen And Legal Constructs In Patent Law, Timothy R. Holbrook, Mark D. Janis

Articles by Maurer Faculty

This Essay is an invited response to The Ghost in the Patent System: An Empirical Study of Patent Law’s Elusive “Skilled Artisan,” by Professors Laura Pedraza-Fariña and Ryan Whalen. In their piece, Pedraza-Fariña and Ryan Whalen offer an empirical study and use it to argue for a new conception of the Person Having Ordinary Skill in the Art (“PHOSITA”), patent law’s nod to the “reasonable person” construct.

As Professors Pedraza-Fariña and Whalen suggest, the PHOSITA should be understood as a crucial concept in patent law, warranting more scholarly attention. Pedraza-Fariña and Whalen provide that attention. They assert, based on an …

Confusing Cy Près, Christopher J. Ryan Jr.

Articles by Maurer Faculty

American courts have increasingly considered the possibility of prolonging the life of charitable trusts through cy près and the closely related doctrine of equitable deviation. This requires courts to interpret the material purposes of trusts and even the administrative terms on which settlors of charitable trusts condition gifts in trust made for public benefit. Yet, the implicit reasons why courts might invoke cy près to change a charitable trust’s material purpose have not been explored in significant depth heretofore—and neither has a common but vexing trend of courts conflating cy près with deviation, which negatively impacts charitable trust-making.

Low-Fidelity Design Optimization And Parameter Sensitivity Analysis Of Tilt-Rotor Evtol Electric Propulsion Systems, Tyler Critchfield, Andrew Ning

Faculty Publications

Urban air mobility requires a multidisciplinary approach to tackle the important chal- lenges facing the design of these aircraft. This work uses low-to-mid fidelity tools to model rotor aerodynamics, blade structures, vehicle aerodynamics, and electric propulsion for a tilt-rotor electric vertical takeoff and landing (eVTOL) aircraft. We use gradient-based design optimization and extensive parameter sensitivity analysis to explore the design space and complex tradeoffs of tilt-rotor distributed electric propulsion systems.
