Impact Of In-Season Potassium Fertilizer Application On Sweetpotato Yields, Alyssa Lynn Hotchkiss

Theses and Dissertations

Sweetpotatoes require approximately three times more potassium (K) than nitrogen (N), making K the most applied nutrient in production. However, K fertilizer recommendations for sweetpotatoes in Mississippi remain outdated or are based on recommendations for other crops. This study evaluated the effects of K fertilizer rate, timing, and application method on sweetpotato production. Field trials were conducted during the 2023 and 2024 growing seasons at the Pontotoc Ridge-Flatwoods Branch Experiment Station in Pontotoc, Mississippi. Treatments included preplant K applications of 0, 134, or 191 kg ha⁻¹ K₂O, in-season sidedress applications of 56 kg ha⁻¹ K₂O, and four foliar K treatments. …

Profiles Of Body Image In Emerging Adults And Associations Across Sociocultural Influences, Alligrace Story

Theses and Dissertations

The Tripartite Influence Model of body image suggests that multiple sources of appearance-related pressures (i.e., family, peers, significant others, and media) impact body image and disordered eating behaviors via appearance-related comparisons and internalization of body-related ideals (i.e., thin-ideal internalization and muscular-ideal internalization). Previous research has shown support for the Tripartite Influence Model of body image among various demographic groups. The current study identified and examined profiles of emerging adults based on their reported body esteem and body appreciation. Body esteem was measured using the Body Esteem Scale for Adolescents and Adults (BESAA; Mendelson et al., 2001), and body appreciation was …

Ethnic Identity And Career Adaptability Among African American High School Students: Exploring The Roles Of Perceived Barriers And Social Support, Zion J. Kamau

Theses and Dissertations

African Americans are subjected to systemic racial discrimination and bias in the labor market. Data on labor force participation collected by the U.S. Census Bureau between 1970 and 2010 were investigated for the purpose of identifying trends, and it was found that race and ethnicity significantly influence an individual's labor market position and employment outcomes (Byars-Winston et al., 2014). African Americans were more likely to hold positions earning less, requiring fewer skills, and associated with a lower social status. There is a misconception that the phenomenon occurs only in adulthood, but it is also observed during adolescence. The U.S. Bureau …

The Role Of Latinx And Hispanic Identity In The Presentation Of Hoarding Symptoms, Caitlyn Ashley Nix

Theses and Dissertations

Although people who identify as Hispanic and Latinx make up approximately 19% of the United States population (U.S. Census Bureau, 2023), most research into hoarding disorder is comprised of White, non-Latinx samples. Thus, the current study investigated Hispanic and Latinx ethnicity as a predictor of several facets of hoarding disorder. Previous literature has shown lower risk for Hispanic and Latinx individuals in terms of several physical health outcomes when compared to individuals of similar socioeconomic status (Markides & Coreil, 1986), though mental health outcomes have more variation by subgroup (Barragán et al., 2020). Previous research has also shown that collectivistic …

An Equity-Centered Creative Therapies Implementation Framework For K-12 School Counseling Practice, Brian Caleb Carlisle

Theses and Dissertations

Adolescents in K-12 schools are experiencing a significant mental health crisis, with rising rates of anxiety, depression, trauma, and emotional dysregulation, while many continue to face limited access to equitable, developmentally appropriate supports. Although schools increasingly serve as primary sites for mental health services, they often lack resources, training, and infrastructures necessary to implement effective interventions. Arts-based and creative therapy approaches demonstrate benefits for emotional regulation, trauma processing, and social-emotional development but remain underused due to inconsistent implementation and systemic barriers. This capstone project examines how creative therapies can be integrated into school counseling programs to address these gaps. Guided …

Enhancing Social Emotional Learning Interventions For Black Adolescent Girls Through Staff Training, Shundrell Mcmullan

Data were collected through semi-structured interviews with five purposively selected school administrators working in high-poverty districts and analyzed using thematic analysis. Findings revealed four central themes: (a) instructional instability resulting from persistent exposure to violence, (b) the spillover of community …

Carbon Dioxide Capture, Utilization, And Storage: A Comprehensive Overview, Katheryn Bailey

Theses and Dissertations

The average global surface temperature is rising, with the 20th-century average being 2.63˚F/1.46˚C above the pre-industrial average, 56.7˚F/13.7˚C. Therefore, research into CO2 capture technology is being explored and implemented as a method to reduce greenhouse gas emissions. The main methods of CO2 capture are pre-combustion, post-combustion, oxy-fuel combustion, and direct air capture. These processes utilize solvent-based absorption, adsorption, membrane separation, and chemical looping combustion to separate CO2 from the exhaust gas. Implementation of this technology can come with increased: material cost, energy penalty, and CAPEX depending on the separation technique, existing equipment, inlet CO2 concentration, and partial pressure, etc.. Financial …

Latent Profile Analysis Of Trauma Appraisal: Associations With Psychological Problems And Substance Use Moderated By Emotion Dysregulation In College Students With Trauma History, Tram Nguyen

Theses and Dissertations

Empirical research suggests that trauma-related appraisals have significant mental health implications. A prior meta-analysis reported that maladaptive trauma-related cognitions play a central role in the development and maintenance of poor coping strategies (i.e., substance use) and posttraumatic stress disorder. However, less is known about the relationships among maladaptive trauma cognitions, emotion dysregulation, and risk for substance use. The current study sought to provide a comprehensive examination of the relationships among trauma appraisals, emotion dysregulation, psychological problems, and substance use. A systematic review highlighted the lack of a person-centered approach to trauma appraisal research, as well as a lack of research …

The purpose of the professional development sessions is twofold. They were created to increase teacher awareness of the etiology …

Telomere-To-Telomere Genome Assembly And A Pangenome For The Rat, Kai Li, Julia L Ciosek, Sergey Koren, Adam M Phillippy, Yaming Zhu, William A Lauer, Shelise Y Brooks, Gerard G Bouffard, Brandon D Pickett, Beth L Dumont, Melissa L Smith, Theodore S Kalbfleisch, Peter A Doris

The Brown Foundation: Institute of Molecular Medicine

We report a complete rodent telomere-to-telomere genome assembly from the brown rat, Rattus norvegicus. Annotation was enriched with multi-tissue long-read RNA sequencing and uncovered numerous novel genes. Assembly of both sex chromosomes reveals the absence of gene coding in the presumed pseudo-autosomal regions and the presence of centromeric satellite repeats on distal chromosome Y (chrY). We provide evidence of meiotic conjunction between Xp and Yq. The genome assembly reveals several expanded autosomal regions enriched for testis-expressed genes. Finally, we have generated a pangenome from recent high-quality assemblies of 8 distinct inbred rat strain genomes. This allows the strain-specific distribution of …

System Leadership For Sdg-Aligned Research Security In Ireland, Seán Lacey

Publications

What is new?

Research security has rapidly emerged as a priority in research governance across Europe and internationally. However, discussions frequently frame research security primarily in terms of national security or geopolitical risk, with limited attention to how security measures intersect with sustainable development objectives. This paper addresses this gap by exploring the relationship between research security and the Sustainable Development Goals (SDGs), using the emerging Irish research security framework as an illustrative context. It argues that research security and sustainable development are not inherently in conflict; however, aligning them requires coordinated system leadership to ensure that security measures protect …
