The Young Black Girl: A Narration Of Stem Identity Through Science Origin In Elementary School, Heather F. Lavender

LSU Doctoral Dissertations

An ethnographic qualitative case study was conducted by examining the perceptions of two 5^th grade Black girls at an independent school about their involvement with school science, the impact of race and gender towards their perception, and the influence of teachers, peers, and family on their science identity. Black girls are often relegated to outsider status within the classroom, lacking power and authority, which results in Black girls being denied a rightful presence in their learning community (Dumas & Ross, 2016). Additionally, their presence in STEM careers does not reflect their presence nationwide (Graves et al., 2014). The proposed …

An Examination Of Yoga To Improve Symptoms Of Post-Traumatic Stress In Firefighters, Amanda Joy Weathers-Meyer

LSU Doctoral Dissertations

Firefighters routinely experience traumatic events while executing their daily occupational duties; in turn, this elevates their risk of experiencing post-traumatic stress symptomatology (PTSS). To successfully contend with repeated trauma exposure, effective and culturally appropriate treatment options for firefighters are needed. A growing body of literature shows that yoga effectively reduces PTSS, notably with those in male-dominated fields. Despite these encouraging findings, the impact of yoga on PTSS among fire service personnel has yet to be examined. Therefore, this dissertation aimed to: (a) obtain preliminary data on yoga’s effectiveness to reduce PTSS in firefighters, (b) investigate cultural appropriateness and firefighter receptivity …

Zeta Potential Measurements For Surface Modification Of Plastic Substrates For Nanofluidic Biosensors, Qinhan Liu

LSU Master's Theses

Polymeric materials have revealed their great potentials in micro- and nano- fluidic devices for biosensing. Their advantages include low cost, various physicochemical properties, well-developed fabrication, and surface modification protocols comparing with traditional materials such as silicon or glass. Surface modification consists an essential step in fabrication of polymer-based biosensors. A proper characterization is required to justify the effectiveness of modifications on polymer surface. For nanofluidic devices, special phenomena such as overlapped electrical double layer, ion rectification and electroosmosis flow can dominate the behavior of single molcules. The concept of surface charge density plays a key role in nanofluidic devices due …

Effects Of Testosterone Undecanoate On Performance During Multi-Stressor Military Operations: A Trial Protocol For The Optimizing Performance For Soldiers Ii Study, Alyssa N. Varanoske, Melissa N. Harris, Callie Hebert, Emily E. Howard, Neil M. Johannsen, Steven B. Heymsfield, Frank L. Greenway, Lee M. Margolis, Harris R. Lieberman, David D. Church, Arny A. Ferrando, Jennifer C. Rood, Stefan M. Pasiakos

Clinical Research Faculty Publications

Background: Previously, young males administered 200 mg/week of testosterone enanthate during 28 days of energy deficit (EDef) gained lean mass and lost less total mass than controls (Optimizing Performance for Soldiers I study, OPS I). Despite that benefit, physical performance deteriorated similarly in both groups. However, some experimental limitations may have precluded detection of performance benefits, as performance measures employed lacked military relevance, and the EDef employed did not elicit the magnitude of stress typically experienced by Soldiers conducting operations. Additionally, the testosterone administered required weekly injections, elicited supra-physiological concentrations, and marked suppression of endogenous testosterone upon cessation. Therefore, this …

Investigating The Determinants Of Student Low Enrollment In Historically Black Colleges And Universities (Hbcus): The Case Of One Hbcu In The South, Anthony Trumaine Jackson

LSU Doctoral Dissertations

There is an undeniable fact that enrollment management efforts on academic campuses have become an integral part of campus finance and the backbone of accreditation. Many Historically Black Colleges and Universities (HBCUs) are on the verge of collapsing and even losing their accreditations due to low enrollment, a decline that has been observed in recent decades.

Therefore, this study investigated why students are not enrolling in HBCUs. The study further explored the perceived factors that are likely to contribute to low student enrollment at HBCUs and the role financial matters play in student enrollment. To address this gap in the …

Internal Entrapment And Fearlessness About Death As Precipitants Of Suicidal Thoughts And Planning In The Context Of Post-Traumatic Stress Disorder (Ptsd), D Nicolas Oakey-Frost

LSU Master's Theses

The post-traumatic stress disorder (PTSD) and suicidal thoughts and behaviors (STB) relationship has been extensively studied but potential explanatory mechanisms remain inconclusive. Entrapment is one variable that evinces a theoretical and empirical mechanistic relationship with PTSD and STB. Further, entrapment and fearlessness about death (FAD) have not been linked but are hypothesized to interact in a way that facilitates vulnerability for intense suicidal thinking and potentially suicidal behavior. The current study examined the indirect effect PTSD symptoms have on suicidal ideation, planning, and likelihood of future suicide attempt through both internal (IE) and external entrapment (EE), moderated by levels of …

The Bidirectional Effects Of Serious Conduct Problems, Anxiety, And Trauma Exposure: Implications For Our Understanding Of The Development Of Callous-Unemotional Traits, Emily Lynne Robertson

LSU Doctoral Dissertations

The association of anxiety and trauma with childhood conduct problems has long been the focus of research, and more recently this area of research has become critical to understanding the development of callous-unemotional (CU) traits. Research in samples of children and adolescents has indicated that those elevated on both CU traits and anxiety seem to show more severe externalizing behaviors and are more likely to show histories of trauma. These findings have typically been interpreted as being indicative of a unique casual pathway to CU traits in those high on anxiety. However, an alternative explanation is that the higher rates …

Total daily energy expenditure (“total expenditure”) reflects daily energy needs and is a critical variable in human health and physiology, but its trajectory over the life course is poorly studied. We analyzed a large, diverse database of total expenditure measured by the doubly labeled water method for males and females aged 8 days to 95 years. Total expenditure increased with fat-free mass in a power-law manner, with four distinct life stages. Fat-free mass-adjusted expenditure accelerates rapidly in neonates to ~50% above adult values at ~1 year; declines slowly to adult levels by ~20 years; remains stable in adulthood (20 to …

Clinical Research Faculty Publications

Introduction Our primary aim was to investigate the association between initial weight change and longer-term changes in weight and compensation (predicted weight loss-observed weight loss) during exercise. As secondary aims, we investigated if initial weight change was related to change in cardiometabolic risk markers and energy balance modulators. Methods Two 6-month randomized controlled exercise trials conducted in individuals with overweight or obesity were analyzed (study 1, n = 312; study 2, n = 102). In both studies, participants in an exercise condition (4 kcal·kg-1·wk-1 [KKW], 8 KKW, 12 KKW, or 20 KKW) were split into tertiles based on percent weight …

The Neural Underpinnings Of Processing Newly Taught Semantic Information: The Role Of Retrieval Practice, Eileen Haebig, Laurence B. Leonard, Patricia Deevy, Jennifer Schumaker, Jeffrey D. Karpicke, Christine Weber

Faculty Publications

Purpose: Recent behavioral studies have demonstrated the effectiveness of implementing retrieval practice into learning tasks for children. Such approaches have revealed that repeated spaced retrieval (RSR) is particularly effective in promoting children’s learning of word form and meaning information. This study further examines how retrieval practice enhances learning of word meaning information at the behavioral and neural levels. Method: Twenty typically developing preschool children were taught novel words using an RSR learning schedule for some words and an immediate retrieval (IR) learning schedule for other words. In addition to the label, children were taught two arbitrary semantic features for each …
