Isolation Of The Toxic Principle Of Senecio Latifolius By Means Of The Sensory Receptors Of Sheep, Leendert D. Snyman

Poisonous Plant Research (PPR)

The aversive substance of Senecio latifolius was isolated by means of the sensory receptors of sheep averted to S. latifolius. Chemical fractions refused due to the presence of the aversive substance sensed by the sheep were fractionated until a purified substance had been isolated. Nuclear magnetic resonance (NMR) analysis of the purified substance showed it to be sceleratine nitrogen oxide, the toxic principle of S. latifolius.

Biophysical Factors Affecting Habitat Suitability For Crassostrea Virginica, Jason D. Tilley

Dissertations

Oyster reefs provide a variety of important ecosystem services. However, the mortality rate of eastern oyster, Crassostrea virginica, the dominant species that produces oyster reefs in the northern Gulf of Mexico, is increasing at an alarming rate due to a variety of abiotic and biological factors. I examined how biophysical factors, including the less-studied fatty acid profiles of the suspended particulate matter on which oysters feed, influenced morphometric condition of C. virginica.

I sampled suspended particulate matter (SPM) and oysters in-situ in the western Mississippi Sound, which historically supported the majority of oyster production in Mississippi waters. Sampling …

Abstinence Restores Cardiac Function In Mice With Established Alcohol-Induced Cardiomyopathy, Joshua M. Edavettal, Nicholas R. Harris, Sarah E. Cohen, Janos Paloczi, Bysani Chandrasekar, Jason D. Gardner

School of Graduate Studies Faculty Publications

Alcohol-induced cardiomyopathy (ACM) has a poor prognosis with up to a 50% chance of death within four years of diagnosis. There are limited studies investigating the potential of abstinence for promoting repair after alcohol-induced cardiac damage, particularly in a controlled preclinical study design. Here, we developed an exposure protocol that led to significant decreases in cardiac function in C57BL6/J mice within 30 days; dP/dt max decreased in the mice fed alcohol for 30 days (8054 ± 664.5 mmHg/s compared to control mice: 11,188 ± 724.2 mmHg/s, p < 0.01), and the dP/dt min decreased, as well (−7711 ± 561 mmHg/s compared to control mice: −10,147 ± 448.2 mmHg/s, p < 0.01). Quantitative PCR was used to investigate inflammatory and fibrotic biomarkers, while histology was used to depict overt changes in cardiac fibrosis. We observed a complete recovery of function after abstinence (dP/dt max increased from 8054 ± 664 mmHg/s at 30 days to 11,967 ± 449 mmHg/s after abstinence, p < 0.01); further, both inflammatory and fibrotic biomarkers decreased after abstinence. These results lay the groundwork for future investigation of the molecular mechanisms underlying recovery from alcohol-induced damage in the heart.

Soil Health In American Sports Fields, Miria C. Barnes

Theses and Dissertations

Healthy soils are essential for sustaining the world's ecosystems and maintaining human lifestyles. The adoption of biological, chemical, and physical analyses to assess soil health is a relatively new concept with a paucity of scientific work assessing how these metrics are affected by field management in urban systems Soil samples (n = 110) were collected from a diverse range of sports fields and, for comparative purposes, golf courses, farm fields, non-sport urban, undisturbed forest, and non-vegetated sandy soils. The samples were then analyzed using biological, chemical, and physical metrics to determine if there were significant differences between sport/golf venues and …

Creating And Implementing A Mentorship Ministry For New Believers, Moses Aleman

Doctoral Dissertations and Projects

A major spiritual crisis exists in the Christian church due to the lack of care and attention given to new believers. Although many churches provide conversion opportunities, they may not prioritize discipleship and support for those who are new to the faith. Consequently, some new believers resign their faith when faced with difficulties, while others may struggle without crucial elements of their faith and doctrine, causing obstacles in their future spiritual journeys. This thesis project argues that having a New Believers Mentorship Ministry is vital and effective in addressing these issues. The project coordinator has three specific expectations for the …

A Phenomenological Study On Veterans’ Military Sexual Trauma And Its Impacts On Intimate Partner Relationships, Jaretta A. Buckholtz

Doctoral Dissertations and Projects

The purpose of this phenomenological study is to describe active duty and military veterans’ experiences with intimate partner relationships after a sexually traumatic event. The theory guiding this study is attachment theory. Therapies such as cognitive behavioral therapy (CBT), cognitive processing therapy (CPT), and eye-movement desensitization and reprocessing (EMDR), demonstrate they could help victims of military sexual trauma (MST) minimize the suffering of post-traumatic stress disorder (PTSD), major depressive disorder (MDD), substance use disorder (SUD), and a host of other debilitating diseases that may have developed as the result of their MST, which could cause difficulties in their intimate partner …

A Cosmic Conflict In Covenantal Literature, Lisa Marie Martinez-Leeper

Doctoral Dissertations and Projects

This dissertation examines the cosmic conflict that God declared in Genesis 3:15 in the Garden of Eden, and that will not come to fruition until the final judgment articulated in Revelation 20. This raging spiritual warfare can be seen through the lens of the covenants God made with Israel and the administration of God’s purposes through His people. Through God’s sovereign hand over Israel, His providence and grace can be seen throughout the whole of Holy Scriptures. The unfolding spiritual conflict to prevent the “seed of the woman” can be clandestinely observed in the outworking of God’s relationship with His …

The Power Of The “Like”: A Quantitative Study On The Facebook Emoji As Social Support, Lina Rawlings

Doctoral Dissertations and Projects

This quantitative study aimed to evaluate how receiving a Facebook “like” correlates to the perception of social support and how much this correlation is moderated by the age and gender of the users. The social information processing theory guided the study, providing a framework to explain how communicators adapt to the restriction of nonverbal cues by creating surrogates to maintain interpersonal relationships in computer-mediated communication circumstances. For the central research question, findings revealed that receiving a Facebook “like” positively correlates with perceptions of social support from Facebook friends and family. While no significant correlation was found between the gender of …

The Perceived Racial Discrimination Of Incarcerated African American Juveniles By Correctional Officers, Jervaughn Fabian Reid

Doctoral Dissertations and Projects

There is an overrepresentation of African American youths at every stage of the juvenile justice system in America, from initial interaction with criminal justice to sentencing and imprisonment. This quantitative correlational study aimed to study the perceived racial discrimination of incarcerated African American juveniles by correctional officers. Statistics indicate that African Americans have a higher probability of offending and incarceration than their White counterparts. Some juveniles are serving long-term sentences, which may go well into adulthood. This study offers general knowledge on what experiences juvenile offenders go through, what promotes such experiences, and how these experiences can affect the population …

Faculty, Staff and Students Publications

The common marmoset (Callithrix jacchus) is one of the most widely used nonhuman primate models of human disease. Owing to limitations in sequencing technology, early genome assemblies of this species using short-read sequencing suffered from gaps. In addition, the genetic diversity of the species has not yet been adequately explored. Using long-read genome sequencing and expert annotation, we generated a high-quality genome resource creating a 2.898 Gb marmoset genome in which most of the euchromatin portion is assembled contiguously (contig N50 = 25.23 Mbp, scaffold N50 = 98.2 Mbp). We then performed whole genome sequencing on 84 marmosets …

Several canonical translocations produce oncofusion genes that can initiate acute myeloid leukemia (AML). Although each translocation is associated with unique features, the mechanisms responsible remain unclear. While proteins interacting with each oncofusion are known to be relevant for how they act, these interactions have not yet been systematically defined. To address this issue in an unbiased fashion, we fused a promiscuous biotin ligase (TurboID) in-frame with 3 favorable-risk AML oncofusion cDNAs (PML::RARA, RUNX1::RUNX1T1, and CBFB::MYH11) and identified their interacting proteins in primary murine hematopoietic cells. The PML::RARA- and RUNX1::RUNX1T1-TurboID fusion proteins labeled common and unique nuclear repressor complexes, implying their …

Visual Afrofuturism And Dieselfunk In The Works Of Tim Fielder, Justin Wigard

Third Stone

Tim Fielder is, first and foremost, a visual Afrofuturist. This distinction is significant in understanding Fielder’s corpus, who works as an illustrator, cartoonist, concept artist, and even animator. Born in Tupelo, Mississippi alongside Jim, his twin brother, Fielder has become an ardent advocate, pioneer, and creator in the 21st-century Afrofuturist movement, creating visual representations of Black people overcoming past, present, and future systems of oppression, all within fantastic and speculative settings.

“Everybody Better Care”: A Qualitative Exploration Of Environmental Documentaries And Psychological Distance, Cassandra Lc Troy

Kaleidoscope: A Graduate Journal of Qualitative Communication Research

Severe problems like climate change, pollution, and biodiversity loss demand urgent action. Unfortunately, people can tend to view such problems as distant, failing to feel that they are relevant to their lives. Psychological distance may play a role in such perceptions. In order to understand how environmental documentaries, which are often used to educate the public about the environment, may influence perceptions of psychological distance, environmental film festival attendees and organizers were interviewed. Qualitative analysis revealed complex reactions to depictions of environmental issues in films, with perceived severity playing a key role in conceptions of spatial, social, and temporal distance. …

Inauthenticity, Delusion, And Victimization: Interrogating Affective Rhetoric Targeting Trans* Youth, Ben Bishop

Kaleidoscope: A Graduate Journal of Qualitative Communication Research

In this essay, I interrogate Texas Attorney General Ken Paxton’s KP-0401, a 2022 legal opinion letter that frames gender affirming healthcare as dangerous, sterilizing, and therefore, child abuse. Within this framing, trans* youth are presented as both delusional and deviant, written off as victims of abuse and social contagion. In analyzing KP-0401 through a critical perspective of affect and performativity, I demonstrate how particular affects have gained power through their circulation to reify feelings and performances of cisheteronormativity, often through establishing the trans* body as a source of negative affect, like fear or repulsion, and trans* youth as infantile and …

"Is This Place Inside Or Outside?": Issues Of Space In Kentucky Route Zero, Jesse Snider

Kaleidoscope: A Graduate Journal of Qualitative Communication Research

Using the video game Kentucky Route Zero as an artifact and the theories of Space and Place of De Certeau, I examine “confused spaces:” places that present simultaneously as two or more contradictory spaces. Through the inevitable confusion between my performance/agency as the game’s player and the performance/agency of the characters within the game, I re-examine De Certeau’s idea of the pedestrian through the lens of twice-behaved behaviors, bureaucracy, remembered religion, inside, outside, and the agency to exert perceived change in one’s environment. Finally, I bring what I learned through Kentucky Route Zero into the realm of the physical, as …

Mediatization Of The Early Automobile: A Visual Analysis Of The Illustrated Press In The Late 19th And Early 20th Century, Nicola Carboni

Artl@s Bulletin

The paper presents a digital analysis of automobile imagery in the early 20th-century press, examining the mediatization of the anti-car movement and the role images played in conveying and furthering the activist discourse. To investigate the phenomenon, the author compiled and analyzed over 5,000 images from in 185 journals published in 45 cities between 1891 and 1950. The analysis revealed a preponderance of positive representations of the automobile in the press, whilst evidence of negative sentiment towards the automobile, such as protests and accidents, was conspicuously absent, with the exception of satirical publications.

Le Musée Des Écoles Étrangères Et Le Spectre De La Guerre En Europe Dans L’Entre-Deux- Guerres, Elena Maria Rita Rizzi

Artl@s Bulletin

Cet article examine si et comment la politique artistique du Musée des Écoles étrangères à Paris dans les années 1920 et 1930 put contribuer à définir l’ « art européen » ainsi que l’espace européen. Il étudie ensuite la seule toile exposée par le musée – Europe, réalisée par l’artiste Ismaël Gonzalez de La Serna vers 1935 – qui prêta une attention particulière au sujet. Tout en mettant cette oeuvre en rapport avec les oeuvres portant sur le même sujet réalisées à l’époque par d’autres artistes, il s’agit, enfin, de comprendre la faible circulation de cette image de l’Europe, qui …
