Nutrient And Microbiome-Mediated Plant–Soil Feedback In Domesticated And Wild Andropogoneae: Implications For Agroecosystems, Amanda Quattrone, Yuguo Yang, Pooja Yadav, Karrie A. Weber, Sabrina E. Russo

School of Biological Sciences: Faculty Publications

Plants influence the abiotic and biotic environment of the rhizosphere, affecting plant performance through plant–soil feedback (PSF). We compared the strength of nutrient and microbemediated PSF and its implications for plant performance in domesticated and wild grasses with a fully crossed greenhouse PSF experiment using four inbred maize genotypes (Zea mays ssp. mays b58, B73- wt, B73-rth3, and HP301), teosinte (Z. mays ssp. parviglumis), and two wild prairie grasses (Andropogon gerardii and Tripsacum dactyloides) to condition soils for three feedback species (maize B73-wt, teosinte, Andropogon gerardii). We found evidence of negative …

Mutational Analysis Of The Nitrogenase Carbon Monoxide Protective Protein Cown Reveals That A Conserved C‑Terminal Glutamic Acid Residue Is Necessary For Its Activity, Dustin L. Willard, Joshuah J. Arellano, Mitch Underdahl, Terrence M. Lee, Avinash S. Ramaswamy, Gabriella Fumes, Agatha Kliman, Emily Y. Wong, Cedric P. Owens

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Nitrogenase is the only enzyme that catalyzes the reduction of nitrogen gas into ammonia. Nitrogenase is tightly inhibited by the environmental gas carbon monoxide (CO). Many nitrogen fixing bacteria protect nitrogenase from CO inhibition using the protective protein CowN. This work demonstrates that a conserved glutamic acid residue near the C-terminus of Gluconacetobacter diazotrophicus CowN is necessary for its function. Mutation of the glutamic acid residue abolishes both CowN’s protection against CO inhibition and the ability of CowN to bind to nitrogenase. In contrast, a conserved C-terminal cysteine residue is not important for CO protection by CowN. Overall, this work …

On The Spectrum Of Mesons In Quenched $Sp(2n)$ Gauge Theories, Ed Bennett, Jack Holligan, Deog Ki Hong, Jong-Wan Lee, C. -J. David Lin, Biagio Lucini, Maurizio Piai, Davide Vadacchino

School of Engineering, Computing and Mathematics

We report the findings of our extensive study of the spectra of flavoured mesons in lattice gauge theories with symplectic gauge group and fermion matter content treated in the quenched approximation. For the $Sp(4)$, $Sp(6)$, and $Sp(8)$ gauge groups, the (Dirac) fermions transform in either the fundamental, or the 2-index, antisymmetric or symmetric, representations. This study sets the stage for future precision calculations with dynamical fermions in the low mass region of lattice parameter space. Our results have potential phenomenological applications ranging from composite Higgs models, to top (partial) compositeness, to dark matter models with composite, strong-coupling dynamical origin. Having …

The Tor Algebra Of Trimmings Of Gorenstein Ideals, Luigi Ferraro, Alexis Hardesty

School of Mathematical & Statistical Sciences Faculty Publications

Let (R,\mathfrak m,\Bbbk ) be a regular local ring of dimension 3. Let I be a Gorenstein ideal of R of grade 3. Buchsbaum and Eisenbud proved that there is a skew-symmetric matrix of odd size such that I is generated by the sub-maximal pfaffians of this matrix. Let J be the ideal obtained by multiplying some of the pfaffian generators of I by \mathfrak m; we say that J is a trimming of I. Building on a recent paper of Vandebogert, we construct an explicit free resolution of R/J and compute a partial DG algebra structure on this …

Dwindling Trust In Experts: A Starting Point For Information Literacy, Mark N. Lenker Iii

Library Faculty Presentations

Librarians and teachers encourage students to include expert perspectives in their research, but recent public discourse includes high-profile examples of experts being inconsistent or wrong, and recent studies suggest that public trust in experts is declining. Waning trust makes it difficult to teach information literacy: I can push students to find high-quality research sources, but what if these sources turn out to be yet another example of experts getting it wrong? After a period of living with this worry, I found a way to move forward by centering class discussion on the public’s dwindling trust in experts. Part of this …

Policy Review And Recommendation For Secondary Education Np-Led Clinics In The Southeastern United States, Shiney Alex Jacob

Student Scholarly Projects

Secondary-level education involves adolescent children aged 11-12 years to 18-19 with unique healthcare needs. Their healthcare is of significant importance as they are transitioning to adulthood, and a majority of them lack access to primary healthcare needs. Advanced Practice Registered Nurses/Nurse Practitioners (APRNs/NPs) provide high-quality, cost-effective, and evidence-based care to people across the lifespan, and there is minimal utilization of their services in meeting the primary care needs of adolescents at the secondary school level. The purpose of the policy project was to determine if current policies and practices related to school health services in three southeastern states of the …

The Accuracy Of Automatic And Human Live Captions In English, Pablo Romero-Fresco, Nazaret Fresno

Writing and Language Studies Faculty Publications

Closed captions play a vital role in making live broadcasts accessible to many viewers. Traditionally, stenographers and respeakers have been in charge of their production, but this scenario is changing due to the steady improvements that automatic speech recognition has undergone in recent years. This technology is being used to create intralingual live captions without human assistance and broadcasters have begun to explore its use. As a result, human and automatic captions co-exist now on television and, while some research has focused on the accuracy of human live captions, comprehensive assessments of the accuracy and quality of automatic captions are …

Behavioural Responses Of Fin Whales To Military Mid-Frequency Active Sonar, Brandon L. Southall, Ann N. Allen, John Calambokidis, Caroline Casey, Stacy L. Deruiter, Selene Fregosi, Ari S. Friedlaender, Jeremy A. Goldbogen, Catriona M. Harris, Elliott L. Hazen, Valentin Popov, Alison K. Stimpert

Faculty Research, Scholarly, and Creative Activity

The effect of active sonars on marine mammal behaviour is a topic of considerable interest and scientific investigation. Some whales, including the largest species (blue whales, Balaenoptera musculus), can be impacted by mid-frequency (1-10 kHz) military sonars. Here we apply complementary experimental methods to provide the first experimentally controlled measurements of behavioural responses to military sonar and similar stimuli for a related endangered species, fin whales (Balaenoptera physalus). Analytical methods include: (i) principal component analysis paired with generalized additive mixed models; (ii) hidden Markov models; and (iii) structured expert elicitation using response severity metrics. These approaches provide complementary perspectives on …

Living In Untranslatability--Performance Art In China And Usa, Ziyun Ma

Masters Theses

This thesis embodies discontinuities in performance art and its non-equivalent Chinese term “行 为艺术” between language and cultural context into a migrating journey. A comparative analysis on the disciplinary history of performance art studies in the US and China laid a foundation in exploring the dynamics of marginality in two contexts. Extracting from the narrative mechanism and body view of Chinese performance art, I demonstrate how the philosophy of living (生) inspired many artistic creation, which also echoes my research journey. And from our mutual living experience, I pose the concept of constructive untranslatability that applies positionality and situated knowledge …

“Little Old Wales”: Expressions Of Nationalism, Language And Pride In Welsh Football, Abigail Mathieson

Masters Theses

Welsh football, through its use of material culture, language, and acknowledgements of history, has become a major force in representing Welsh national identities locally and globally. This thesis expands on Benedict Anderson’s idea of the “imagined community” through contemporary research from academic sources and from voices throughout the Welsh footballing community. It highlights the significance of the sport in national identity, especially within smaller nations such as Wales with histories of post-colonialism. Along with this, football shows the role cultural nationalism plays in the nation of Wales and in its independence movements.

Cannabis-Induced Psychotic Disorder And Schizophrenia Diagnostic Comparison, Tyanna Brodhagen

Honors Theses

Recent changes in cannabis legalization will have broad societal impacts for decades to come, not the least of which are the unknown consequences to neuropsychiatric health, particularly for adolescents and young adults. Cannabis-induced psychotic disorder (CIPD) is a controversial and poorly understood neuropsychiatric condition characterized by a psychotic experience brought on by excessive cannabis intoxication and/or withdrawal. Although CIPD is currently an uncommon diagnosis, the overlapping symptomology and comorbidity with schizophrenia indicates CIPD may be underdiagnosed. Some authors suggest the under diagnosis of CIPD may be correlated to physician diagnostic practices. This honors thesis constitutes a scholarly literature review and …

Identification Of Candidate Dna Methylation Biomarkers Related To Alzheimer’S Disease Risk By Integrating Genome And Blood Methylome Data, Yanfa Sun, Jingjing Zhu, Yaohua Yang, Zichen Zhang, Hua Zhong, Guanghua Zeng, Dan Zhou, Richard S Nowakowski, Jirong Long, Chong Wu, Lang Wu

Faculty, Staff and Student Publications

Alzheimer disease (AD) is a common neurodegenerative disease with a late onset. It is critical to identify novel blood-based DNA methylation biomarkers to better understand the extent of the molecular pathways affected in AD. Two sets of blood DNA methylation genetic prediction models developed using different reference panels and modelling strategies were leveraged to evaluate associations of genetically predicted DNA methylation levels with AD risk in 111,326 (46,828 proxy) cases and 677,663 controls. A total of 1,168 cytosine-phosphate-guanine (CpG) sites showed a significant association with AD risk at a false discovery rate (FDR) < 0.05. Methylation levels of 196 CpG sites were correlated with expression levels of 130 adjacent genes in blood. Overall, 52 CpG sites of 32 genes showed consistent association directions for the methylation-gene expression-AD risk, including nine genes (CNIH4, THUMPD3, SERPINB9, MTUS1, CISD1, FRAT2, CCDC88B, FES, and SSH2) firstly reported as AD risk genes. Nine of 32 genes were enriched in dementia and AD disease categories (P values ranged from 1.85 × 10-4 to 7.46 × 10-6), and 19 genes in a neurological disease network (score = 54) were also observed. Our findings improve the understanding of genetics and etiology for AD.

Connecting With A Lost Heritage: The Indigenous Taino Community Of The Caribbean In New York City, Angeles R. Rodriguez Negron

Capstones

Among New York City's diasporic communities lie the Indigenous Tainos, an aboriginal people originally from the Caribbean region. But many people are unaware of their existence. There is a belief among Puerto Ricans and other Caribbean societies that the Tainos are an extinct tribe since the 16th century due to European colonization. The Taino revivalist movement has taken strength during the last 30 years, and more Taino descendants are taking pride on their identity and culture. After 5 months of collaboration with this Indigenous community, Puerto Rican journalist Ángeles Rodríguez Negrón created Miyari Taino, a podcast designed to provide visibility …

The New New Yorkers, Frances E. Perozo

The Pima County Jail In A “State Of Full-Blown Crisis”: Inmate Deaths Four Times The National Average, Natalie Robbins

Capstones

Last year, 12 inmates died in custody at the Pima County Jail in Tucson, Arizona. With a 10-year average jail population of 1,827, that is a per capita rate of 656.8 deaths per 100,000 inmates.

According to the most recent data from the Bureau of Justice Statistics, the 2019 national local jail mortality rate was 167 deaths for every 100,000 inmates, making the Pima County Jail’s 2022 per capita death rate nearly four times as high as the national average in 2019.

In a December 2022 memo to the Pima County Board of Supervisors, Pima County Sheriff Chris Nanos wrote …

“Unsanitary, Rundown, Everything Is Broken”: The Reality Of Queer Homeless Shelters, Sunjum Nagpaul

Capstones

Despite the larger need for queer-designated shelters, there are only a handful of them out of hundreds of city shelters. Most of them are for youth except Marsha’s House, located in Belmont in the Bronx, which has an age limit of 30. It also comes with a slew of concerns, like staff who are unfamiliar with LGBTQ+ issues and a layout that can exclude those with physical disabilities. What’s more, queer residents face many of the same challenges others homeless do: dirty and unsanitary facilities that never seem to improve.

This piece focuses on how New York City’s composting programs have adjusted after losing funding from the city government at the beginning of 2024. While there has been coverage about the issue at a larger policy level, there has not been a lot of attention paid to the small local gardens who are just as affected by this change as the larger organizations. The piece interrogates the issue from the bottom up, starting with small community gardens and ending with the larger organizations that support their work. It also looks at the issue from the perspective of the Department of …

Exodus: The Cost Of Leaving High-Control Religion And Life After Breaking Free, Hannah-Kathryn Valles

Capstones

There are many names for those who leave their faith community—apostate, heretic, dissenter. While there is no singular path to parting with one’s religious beliefs, the experience can be fraught and intensely painful. For those in high-control religious environments, the price of leaving is even steeper.

When identity, social connections, finances, and family structures are dependent on conforming to strict religious and ideological norms, the decision to leave can have far-reaching consequences. For those who do make the bold decision to leave, it’s hardly the end of the road. In many ways, leaving is just the first step toward finding …
