The first paper investigates tundra vegetation productivity trends which have decreased in the Yukon-Kuskokwim Delta despite increasing temperatures during the growing season, contrasting with other Arctic tundra regions. Using available long-term climate datasets, a coherent multi-decadal pattern involving spring sea-ice concentration in …

Does Emotion Regulation Capacity Moderate Social Anxiety Risk Given Experiences Of Racial Microaggressions In Black/African American Undergraduate Students?, Alisha M. Sylvester

Honors College Theses

Racial microaggressions are intentional or unintentional slights toward members of a marginalized community that may come in the form of verbal, behavioral, or environmental insults. Black/African Americans experience racial microaggressions frequently, and these experiences threaten mental health. Specifically, experiencing more racial microaggressions is linked with a risk for social anxiety. However, not all individuals within the community go on to experience social anxiety. Therefore, the present study sought to identify which individuals are more vulnerable to social anxiety given experiences of racism. Poorer emotion regulation (i.e., the ability to manage emotions) is a known risk factor for anxiety. Thus, I …

Bala, Marco Arriaga, Natasha Garcia-Rodriguez, Renee Hernandez, Satish Kumar, John Blangero, Sarah Williams-Blangero

School of Medicine Publications

Nonalcoholic Fatty Liver Disease (NAFLD) is a prevalent and complex condition influenced by both genetic and environmental factors. This chapter explores the genotype-by-environment interactions that contribute to the development and progression of NAFLD in the Mexican American population. Using advanced genetic epidemiology and bioinformatics approaches, we investigated how specific genetic variants interact with environmental factors such as depression, acculturation stress, and social determinants of health, to influence NAFLD risk and severity. Our findings reveal significant genotype-by-environment interactions for key NAFLD-related traits, including HbA1c, AST/ALT ratio, and steatosis-controlled attenuation parameter (CAP). We also discuss the application of cutting-edge proteomic and transcriptomic …

Understanding Sequence Determinants Of Functional Protein Dynamics Using Biophysical Simulations And Experiments, Upasana Lakshmi Mallimadugula

Arts & Sciences Graduate Student Theses and Dissertations

Mutations in the sequence of proteins associated with a disease often increase its risk or severity. They can also be a barrier to developing effective therapeutics for such diseases. One way in which mutations affect function is by altering dynamics that elude structural studies. Observing these changes requires methods that can report on movements of the protein on various timescales and is an ongoing challenge in biophysics and biochemistry. In this study I will use both experimental and computational techniques that can report on such dynamics to explore how small sequence changes shift the conformational landscape and consequently the function …

Avian Adaptation To Thermal Gradients, Justin Wheeler Baldwin

Arts & Sciences Graduate Student Theses and Dissertations

Life on Earth has adapted to extremely different temperatures worldwide. However, across distant branches of the tree of life, animals in similar temperature environments often share similar phenotypic traits. Specifically, traits that bear on the ratio between an individual’s surface area (e.g. appendage length) and its volume (e.g. body size) are particularly important for temperature regulation and are codified in canonical biogeographical rules. Although these global patterns of finding larger-bodied (Bergmann’s Rule) and shorter-limbed (Allen’s Rule) animals in colder regions are widely upheld, they also show substantial variation. It remains poorly understood why some animals conform to these biogeographical rules …

Sustainable Plastics From Plastic Metabolisms: Leveraging Purple Non-Sulfur Bacteria For Polyhydroxyalkanoate Synthesis, Eric Michael Conners

Arts & Sciences Graduate Student Theses and Dissertations

Purple non-sulfur bacteria (PNSB) are a taxonomically diverse group of gram-negative bacteria representing some of Earth’s most metabolically versatile life, with many genera capable of switching between the four major metabolic modes – chemoheterotrophy, chemoautotrophy, photoheterotrophy, and photoautotrophy. Today, we exploit this diversity to explore fundamental questions about microbial metabolism. At the same time, many researchers are eager to use PNSB as tools for biotechnological innovations. Yet there exists a gap between fundamental biology and applied science. Part of the challenge is that we rely on a handful of model organisms – namely, members of the genera Rhodopseudomonas and Rhodobacter …

The Revised Cdc Chronic Pain Guidelines And Payer Opioid Analgesic Policies In Michigan, Victoria Tutag Lehr, Cynthia L. Arfken

Michigan Journal of Public Health

Abstract

The 2016 publication of A Guideline for Prescribing Opioids for Chronic Pain by the Centers for Disease Control and Prevention motivated commercial and Medicaid payers to restrict their opioid prescribing policies including the imposition of hard limits on opioid daily dosages and duration. One result of these policies was an increase in abrupt opioid discontinuation and rapid tapering events for patients receiving long-term opioid therapy. Responding to this misapplication of the 2016 guideline, the 2022 revised guidelines emphasized individualized opioid therapy and exclusion of certain chronic diseases. However, it is not known if the payers changed their policies to …

Machine-Learning And Game-Theoretic Inspired Strategies For Adversarial Freeze-Tag, Matthew Giacovelli

Theses

In this thesis, we explore three machine-learning and game-theoretic inspired strategies to address the Freeze-Tag Problem with adversarial agents (FTPA). We develop a custom Gymnasium envi- ronment where unfrozen robots collaborate to “tag” and unfreeze immobile frozen robots while avoiding being tagged by the adversaries. The FTPA models scenarios such as restoring disabled relay towers after a cyberattack where different towers vary in priority, repair difficulty, and ad- versarial threats. We evaluate three strategies: a baseline heuristic where unfrozen robots target the nearest untargeted frozen robot, a hierarchical approach that incorporates adversary interac- tions and likelihood of success into decision-making, …

Undeserving And Underserved: Violence Victims And Society, Venita Monet C. D'Angelo

Theses

This capstone includes three papers that explore how structural disadvantage, place-based dynamics, and institutional responses shape the experiences of individuals and communities. The first paper focuses on the relationship between concentrated disadvantage, micro-places, and individual outcomes. It shows how crime is not randomly distributed but clusters in specific locations within disadvantaged neighborhoods. Drawing on theories of social disorganization and cumulative disadvantage, the paper explains how neighborhood and micro-place conditions intersect to shape long-term risks and outcomes for residents. The second paper analyzes a community-based intervention designed to reduce recidivism and revictimization. The evaluation considers the program’s design, goals, and limitations, …

Guidelines For Returning To Dance Following Concussion: Adaptations From Sport Concussion Literature, Sheyi Ojofeitimi, Lauren Mcintyre, Elizabeth Barchi, Sarah S. Rae, Brittney Winnitoy, Jeffrey A. Russell

Department of Family & Community Medicine Faculty Papers

Sport concussion receives substantial attention as a public health concern. Conversely, performing artists, including dancers, sustain concussions, but these aesthetic athletes do not receive the same level of consideration nor care for this injury as that offered to traditional athletes. The concussion literature pertaining to dance is sparse, and, to our knowledge, no recommendations exist for the crucial aspect of care related to returning to dance following a concussion. The purpose of this article is to assimilate the current knowledge about post-concussion return to activity management in sport—the closest analog of the physical demands required in dance—as a means to …

A Range Extension For Carex Sartwellii In Interior Alaska, Mark A. Winterstein

Biological Sciences

Mean annual temperatures and growing season length have been increasing in northern latitudes. This has impacted permafrost thaw and the water balance of northern regions, resulting in a pattern of drying lakes in the Yukon Flats, Alaska. As lakes dry, they expose lake sediments to colonization by terrestrial vegetation. Recent interest in the terrestrial response to climate change and its effects on ecosystem services led to the formation of the Yukon River Basin project. As a part of this project, we studied plant succession and diversity in the drying lake basins. In the course of our field work we encountered …

Old, Not Odd: Running Laches Against The States And The Future Of Antitrust After New York V. Meta Platforms, Frank Schulze

Michigan Law Review

In New York v. Meta Platforms, Inc., the United States Court of Appeals for the D.C. Circuit applied equitable laches to an antitrust lawsuit brought by forty-six state attorneys general, holding that they had not brought their claims in their role as law enforcers. Meta Platforms is the latest in a line of cases that has characterized antitrust actions by state attorneys general as non-public and non-governmental. But this characterization is in tension with the historical role of state attorneys general in enforcing the antitrust laws and undermines the original design of the federal antitrust statutes as supplements to …
