Race-Based Stressors And Racial Trauma: The Moderating Role Of Parental Racial Socialization, Jessica S. Philip

Graduate Research Theses & Dissertations

Experiences of race-based stressors are linked with worse psychological outcomes for racial/ethnic minority individuals (e.g., Ferdinand et al., 2015). The way in which parents talk to their children about race (i.e., racial/ethnic socialization; RES) may exacerbate or buffer against the strength of this link (e.g., Keum & Ahn, 2021). Therefore, the present study examined the links between race-based stressors, RES, and psychological outcomes (i.e., depression, anxiety, stress, racial trauma) across multiple racial/ethnic minority groups. The present study also explored the different RES messages as potential moderators for the link between race-based stressors and outcomes, as well as differences in these …

Exploring The Connection: Field Ecology Research And Student Wellbeing, Elizabeth Small

Graduate Research Theses & Dissertations

Field work is essential in ecological research, offering the opportunity to gather firsthand data, observe natural processes, and deepen our understanding of ecosystems. In my study on small mammal trophic niche dynamics, I investigate how small mammals—critical players in grassland food webs—adapt their diets in response to environmental disturbances. By examining the drivers of variation in trophic niche among three common small mammal species, I aim to uncover how these animals coexist despite similar dietary requirements. Understanding these dynamics is critical for informing global conservation efforts, especially as we work to reverse the biodiversity crisis and restore damaged ecosystems.However, the …

Leveraging Bioinformatics To Understand Chlorophyll D Biosynthesis In Acaryochloris Spp., Dikshyant Gautam

Increasing Retention Of Women In Hunting And Fishing, Shelby Isensee

Electronic Theses and Dissertations

Despite national declines in hunting and fishing, women are making inroads in historically male-dominated sports. To further encourage women’s participation, states established programs to recruit, retain, and reactivate [R3] hunters and anglers. Women are participating in these programs and other recreational groups to access opportunities to learn skills and grow their networks. Yet, very little is known about what programs are offered for women, what aspects of programs are most effective to support women’s retention in these activities, and what women’s hunting and fishing groups are available across the landscape. To address these questions, I collected qualitative data from participant …

Dna Methylation In Aging And Alzheimer's Disease, Raymond Cheng, Jingmin Shu, Hai Chen, Ming Li, Xiaodong Cheng, Li Liu

The Brown Foundation: Institute of Molecular Medicine

DNA methylation undergoes significant changes with age. These alterations play a pivotal role in the development of age-related diseases, including Alzheimer's disease (AD). Recent advancements in DNA methylome profiling have revealed global hypomethylation patterns, particularly within repetitive elements, as well as gene-specific changes that are associated with neurodegeneration. Age-related alterations in DNA methylation have been implicated in the disruption of key cellular processes, such as inflammation and proteostasis, both central to AD pathology. However, several challenges persist in this field. One major issue is the inconsistency of findings across different brain regions and tissue types, which complicates result interpretation. Furthermore, …

A Simple And Rapid In Vitro Assay For Identification Of Direct Inhibitors Of O6-Methylguanine-Dna Methyltransferase, Vahid Khalaj, Solmaz Aghaamiri, Sukhen C Ghosh, Servando Hernandez Vargas, Majid Momeny, Ali Azhdarinia

The Brown Foundation: Institute of Molecular Medicine

O6-Methylguanine-DNA methyltransferase (MGMT) is a DNA repair enzyme that is overexpressed in certain tumors and is associated with resistance to the DNA alkylating agent temozolomide. MGMT inhibitors show potential in combating temozolomide resistance, but current assays for MGMT enzyme activity and inhibition, primarily oligonucleotide-based and fluorescent probe-based, are laborious and costly. The clinical relevance of temozolomide therapy calls for more convenient methodologies to study MGMT inhibition. Here, we extended the application of SNAP-Capture magnetic beads to develop a novel MGMT inhibition assay that demonstrated efficacy not only with known MGMT inhibitors, but also with the aldehyde dehydrogenase inhibitor, disulfiram. The …

Fetal Abdominal Obesity In Women With One Value Abnormality On Diagnostic Test For Gestational Diabetes Mellitus, Wonjin Kim, Soo Kyung Park, Yoo Lee Kim

The Brown Foundation: Institute of Molecular Medicine

Previous studies have shown that fetal abdominal obesity (FAO) was already observed at the time of gestational diabetes mellitus (GDM) diagnosis and persisted until delivery despite management in older and/or obese women. In this study, we investigated whether fetuses of women with milder hyperglycemia than GDM have accelerated abdominal growth, leading to adverse pregnancy outcomes. We retrospectively reviewed the medical records of 7,569 singleton pregnant women who were universally screened using a 50-g glucose challenge test (GCT) and underwent a 3-h 100-g oral glucose tolerance test (OGTT) if GCT result was ≥140mg/dL. GDM, one value abnormality (OVA), and normal glucose …

Reorganization Of Dopamine Circuitry In The Anterior Corpus Callosum Between Early Adolescence And Adulthood In The Mouse, Megan Caldwell, Josue Criollo Mendoza, Xin Yan Zhu Jiang, Colin Alarcon, Vanessa Ayo-Jibunoh, Shelby Louis, Daniel Maronna, Rania Darwish, Jaquelyn Tomaio, Susana Mingote, Leora Yetnikoff

Advanced Science Research Center

The maturation of forebrain dopamine circuitry occurs over multiple developmental periods, extending from early postnatal life until adulthood, with the precise timing of maturation defined by the target region. We recently demonstrated in the adult mouse brain that axon terminals arising from midbrain dopamine neurons innervate the anterior corpus callosum and that oligodendrocyte lineage cells in this white matter tract express dopamine receptor transcripts. Whether corpus callosal dopamine circuitry undergoes maturational changes between early adolescence and adulthood is unknown but may be relevant to understanding the dramatic micro- and macro-anatomical changes that occur in the corpus callosum of multiple species …

Mid-way through the study, Allport’s (1954) contact hypothesis was included to inform the revision of intervention approaches. Four elementary teachers attended seven in-person informational discussion meetings over five months. During this time, these teachers also read two books and completed journal responses and surveys. The qualitative data was analyzed using Braun and Clark’s (2006) …

Frequent Use Of Contingency Management And Opioid Treatment Programs That Provide Treatment For More Than Only Opioid Use Disorder, Orrin D. Ware, Matthew D. Novak, Forrest Toegel

Journal Articles

Contingency management is an effective behavioral intervention for treating substance use disorders that provides patients with incentives for objective verification of completed targeted recovery behaviors including abstinence from substances, attending treatment, and medication adherence. Accredited/licensed opioid treatment programs provide effective, medications for opioid use disorder. This study evaluated the prevalence of frequent contingency management use among a national sample of opioid treatment programs in the U.S. (N= 672). A binary logistic regression model examined factors associated with providing contingency management, including state-level fatal overdoses, number of pharmacotherapies, outpatient treatment, facility ownership, and residential treatment.

Comparing The Predictive Capacity Of Allometric Models In Estimating Grass Biomass In A Desert Grassland, Adam T. Naito, Steven R. Archer, Philip Heilman

Journal Articles

Allometric models provide a rapid, nondestructive means for estimating aboveground biomass (AGB) of perennial grass species. In the absence of site-specific models, allometric relationships developed at other sites at other times are often used. This implicitly assumes that size-biomass relationships are highly robust. In this study, we assess the comparability of allometric relationships developed at two points in time (2005 and 2015) on different soils on a Sonoran Desert savanna in southern Arizona. We used peak growing season field measurements to develop single-species and multispecies regression models using basal diameter and height to predict the current year's AGB for seven …

Strategic Planning In Higher Education: Perceptions Of Faculty And Administrators At Public Institutions., Brent Graves, Fritz J. Erickson

Journal Articles

Over the past several decades, strategic planning has become ubiquitous in higher education. Yet, there are varying perceptions of its overall value. Perceptions of value are critically important as they can influence the effectiveness and breadth of participation in the strategic planning process, and such participation is widely held to be critical for success. We investigated these issues using an on-line survey distributed to faculty, chairs, and deans at public colleges and universities in the United States. We found that, compared to both faculty and chairs, deans had a more positive assessment of whether the benefits of the process were …

Dust-Driven Mechanism For Marine Particle Aggregation: Interactions Between Clay Minerals, Heterotrophic Bacteria And Organic Matter Influences Aggregation In Marine Systems, Vignesh Gokuladas Menon

Benthic And Epibenthic Invertebrate Assemblages Associated With Estuarine Submerged Aquatic Vegetation Differ Between Native And Invasive Plants, Marissa Hall, Kathryn O'Shaughnessy, Bethany Kiley, Ashley Mcdonald, Taber Faurie, Zoey Hendrickson, Anna Reimer, Samantha Smith, Charles Martin

Gulf and Caribbean Research

Estuarine submerged aquatic vegetation (SAV) provides vital habitat for macroinvertebrate communities that support diverse food webs and subsequent ecosystem services. Invasive SAV, however, has the potential to alter estuarine food webs through competition with native SAV, resulting in different associated biological communities. In the Mobile-Tensaw Delta (Alabama, USA), the invasive Eurasian milfoil, Myriophyllum spicatum, is fast becoming the dominant SAV, out-competing native SAV such as wild celery, Vallisneria americana. This study investigated the above- and belowground macroinvertebrate assemblages associated with these SAV habitats. We found significantly different assemblages between the SAV, with V. americana supporting more even and …

Weeds To Wealth: Upcycling Emilia Sonchifolia To Biobased Batteries, Arielle E. Myerson, Lauren Whetstone

High Impact Practices Student Showcase Spring 2024

Lithium ion (Li-ion) battery technology typically requires graphite as the conductive material for the anodes. Graphite is an unsustainable material which is either synthetically manufactured from fossil fuels or mined and imported. To replace graphite anodes, silicon-based materials such as silicon oxycarbide (SiOC) can be used along with bio-based carbon sources to make even more energy-dense anodes than traditional graphite. The lignins that comprise plant cell walls are an excellent biological source of carbon. Therefore, invasive weeds, such as Emilia Sonchifolia (lilac tassel flower) are a good candidate for building sustainable Li-ion batteries. In this research, the weeds were collected, …
