The Influence Of Life Skills, Teammate And Coach Behavior, And The Sport Environment On The Mental Well-Being Of Intercollegiate Athletes, Lauren A. Shute

LSU Doctoral Dissertations

Abstract

Intercollegiate athletics generate significant interest in the United States, where concerns about the health and well-being of student-athletes have gained increased attention in recent years. Student-athletes face the same developmental challenges as their non-athlete college peers, but they also encounter biological, psychological, sociocultural, and spiritual challenges often introduced or exacerbated by their participation in sport. To assist this subgroup of the college student population in managing their various athletic, academic, and personal responsibilities, the National Collegiate Athletic Association (NCAA) has prioritized and implemented life skills programming. Yet, while much has been documented regarding life skills development at the youth …

From low retention rates to race and gender biases to being overworked and undervalued in the classroom, Black women leave education at higher rates than any other demographic. This study highlighted the experiences of Black women in K-12 education settings, the role of support systems in their retention and advancement, and why they stay in K-12 education. The study used Counter-storytelling in Critical Race Theory, Black Feminist Thought, and Womanism to examine the race and gender inequities that Black women face and to highlight their lived experiences. Through the use of Sista Circles/focus groups and one-on-one interviews, the research …

Intraspecific Variation In Morphological And Biochemical Responses To Salinity And Flooding In Phragmites Australis, Olivia Hurley

LSU Master's Theses

Phragmites australis is a widespread wetland plant species with numerous haplotypes, several of which are highly invasive. In low-lying coastal marshes of Louisiana, the Delta-type (haplotype M1) dominates across a wide range of salinity and flooding environments. This suggests that Phragmites may be highly adaptable to diverse environmental conditions and that there may be a genetic component, as seen in other coastal wetland plant species. While non-native Phragmites haplotypes are targeted for control and removal in many areas, they are considered beneficial for marsh stabilization and contributing to elevation gain in coastal Louisiana, where several areas experience rapid land loss. …

Oral Hygiene And Cardiovascular Health, Md. S. Zaman, S. M. Golam Alam, Mohammed S. Razzaque

School of Medicine Publications

The human oral microbiome plays a vital role in maintaining oral and systemic health. This diverse microbial community includes over 700 bacterial species, some of which are implicated in developing systemic diseases, particularly cardiovascular diseases (CVDs). Research highlights a strong association between periodontal disease and increased cardiovascular risk, suggesting that good oral hygiene practices may reduce the incidence of CVDs. Porphyromonas gingivalis and Fusobacterium nucleatum drive chronic inflammation in periodontal disease; these bacteria can extend beyond the mouth and contribute to systemic inflammatory responses. The inflammatory factors, including C-reactive protein (CRP), interleukins (IL-1, IL-6), and tumor necrosis factor-alpha (TNF-α), damage …

Computed Microtomographic Imaging Of Revascularization During Healing Of Achilles Tendon Injury, Seher Yilmaz, Ozan Akkus

Faculty Scholarship

Angiogenesis in injured tendons may contribute to regeneration, but quantifying it post-injury has been mostly limited to 2D semi-quantitative histology. This study aimed to develop micro-CT as a 3D tool to quantitatively assess tendon blood vessels in an experimental animal model. Adult male Wistar rats (N = 36) had injuries induced in their Achilles tendons by needle insertion. The study included three post-injury groups: 12 hours post-injury (12H), 3 weeks post-injury (3W), and 8 weeks post-injury (8W). The uninjured left Achilles tendon served as the control for each group. Intravital cardiac perfusion with barium sulfate enhanced contrast between tendon and …

Dissecting The Contribution Of Stmn2 To Als Pathogenesis, Kelsey Krus

Arts & Sciences Graduate Student Theses and Dissertations

TDP-43 is required for splicing of Stathmin-2 (STMN2) transcript, so STMN2 is reduced in most ALS patients. TDP-43 does not regulate STMN2 in mice as it does in humans. Thus, mouse models of ALS do not reflect patient loss of STMN2. To test the hypothesis that a reduction in STMN2 contributes to ALS pathogenesis, we generated STMN2 knockout mice. Constitutive STMN2 loss induces an early sensory and motor neuropathy with disrupted motor behavior and dramatic distal neuromuscular junction (NMJ) denervation. This NMJ pathology occurs in fast-fatigable motor units, which are the most vulnerable in ALS. In contrast, motoneurons and axons …

Anxiety Sensitivity And Intolerance Of Uncertainty Uniquely Explain The Association Of The Late Positive Potential With Generalized Anxiety Disorder Symptoms, Matt R. Judah, Hannah C. Hamrick, Benjamin Swanson, Morgan S. Middlebrooks, Grant S. Shields

Psychological Science Faculty Publications and Presentations

Studies suggest that generalized anxiety disorder (GAD) symptoms are related to late positive potential (LPP) responses to negative images, suggesting greater attention. Anxiety sensitivity (AS) and intolerance of uncertainty (IU) are cognitive factors in GAD vulnerability that may be activated by negative stimuli, thereby explaining why the LPP and GAD symptoms are related. We examined whether AS and IU explain the association of the LPP with GAD symptoms. Eighty-seven (77% women) young adults viewed 60 negative and 60 neutral images. The LPP was examined using both frequentist and Bayesian approaches. This revealed unique indirect effects of the LPP on GAD …

Acceptance And Commitment Therapy-Enhanced Behavior Therapy As An Intervention For Trichotillomania And Excoriation Disorder (Skin Picking): A Review, Michael P. Twohig, Leila K. Capel

Psychology Faculty Publications

Acceptance and commitment therapy (ACT) – enhanced behavior therapy (A-EBT) is the most empirically supported treatment for trichotillomania. The data supporting A-EBT for excoriation disorder (skin picking) is small but growing. In this paper we review the model behind A-EBT including support for targeting psychological inflexibility as well as the use of more traditional behavioral procedures to reduce non-focused behaviors. To date there are 15 studies investigating A-EBT for trichotillomania and skin picking across ages and treatment delivery methods (individual, group, telehealth, and asynchronous web-based delivery). The work has occurred by multiple research teams. Data on process of change is …
