Essays On Poverty And Infant Health, Deokrye Baek

LSU Doctoral Dissertations

In this dissertation, I offer three independent studies that each contribute to the literature on poverty and infant health. The first essay examines whether access to public transportation reduces food insecurity in the U.S. Potential endogeneity problem is addressed with instruments of federal transportation funding. I provide new evidence of a negative causal effect of public transportation accessibility on food insecurity, which is more prominent among poor African-American households. The second essay examines the relation between savings of poor households and a welfare program called the Supplemental Nutritional Assistance Program (SNAP). Eligibility for SNAP benefits requires households to own limited …

The Effects Of Concurrent Driving And In-Vehicle Tasks: A Multivariate Statistical Analysis Of Driver Distraction In A High-Fidelity Driving Simulator, Julius A. Codjoe

LSU Doctoral Dissertations

Distracted driving continues to remain a cause of concern for a number of bodies, including government agencies, traffic safety advocacy groups and law enforcement agencies, because of its traffic safety risks. The driving simulator continues to be popular with researchers in collecting data on performance variables that provide scientific knowledge of the effects of distracted driving. Several of these performance variables can be used to quantify a single distracting effect, resulting in a multivariate dataset. A literature review of related studies revealed that researchers overwhelmingly use univariate (single and multiple) tests to analyze the resulting dataset. Performing multiple univariate tests …

Thermodynamics Of Dna Binding By Dna Polymerase I And Reca Recombinase From Deinococcus Radiodurans, Jaycob Dalton Warfel

LSU Doctoral Dissertations

Deinococcus radiodurans has a significantly more robust DNA repair response than Escherichia coli, which helps it survive high amounts of oxidative stress. D. radiodurans DNA Polymerase I (DrPolI) and RecA protein (DrRecA) play essential parts in this DNA repair capability. Structural stability studies of the DrPolI large fragment (Klendra) and examination of the DNA binding characteristics of Klendra and RecA are presented herein. In the absence of cofactors DrRecA binds to dsDNA more than 20 fold tighter than EcRecA, and binds ssDNA up to 9 fold tighter. Binding to dsDNA in the absence of cofactor presumably monitors DNA end binding. …

Revealing The Jewishness Of Hannah Arendt, Jennifer Richard

LSU Doctoral Dissertations

Hannah Arendt, one of the most important political thinkers of the twentieth century, passed away before finishing her final statement on politics. Because her political theory is incomplete, scholars have adopted many means for interpreting her work. In this dissertation, I adopt a phenomenological approach to understanding Arendt by engaging with the phenomenological method Arendt, herself, used—narrative. I specifically employ the Passover narrative as a metaphorical framework alongside which Arendt’s political theory is traced. In this approach, four elements of Arendt’s theory emerge to distinguish her thought from the Western political tradition: the role of the mental activities, the definition …

Space-Efficient Data Structures For String Searching And Retrieval, Sharma Valliyil Thankachan

LSU Doctoral Dissertations

Let D = {d_1, d_2, ...} be a collection of string documents of n characters in total, which are drawn from an alphabet set Sigma =[sigma] ={1,2,3,...sigma}. The top-k document retrieval problem is to maintain D as a data structure, such that when ever a query Q=(P, k) comes, we can report (the identifiers of) those k documents that are most relevant to the pattern P (of p characters). The relevance of a document d_r with respect to a pattern P is captured by score(P, d_r), which can be any function of the set of locations where P occurs in …

Some Numerical And Phenomenological Studies In Loop Quantum Cosmology, Brajesh Kumar Gupt

LSU Doctoral Dissertations

A key feature of the singularity resolution in loop quantum cosmology (LQC) is the occurrence of the quantum bounce when the spacetime curvature becomes comparable to the Planck scale. The presence of quantum bounce greatly modifies the dynamics of the early universe and can have important implications for observational signatures. Although the quantum bounce has been previously studied via numerical methods for initial conditions that correspond to large macroscopic universes at late times, a detailed study of the robustness of the quantum bounce for a generic class of initial condition has so far been missing due to severe computational challenges. …

Energy Dissipation And Entropy Generation During The Fatigue Degradation: Application To Health Monitoring Of Composites, Ali Kahirdeh

LSU Doctoral Dissertations

In this dissertation, an experimental approach for characterizing energy dissipation and degradation evolution in a woven Epoxy/Glass (G10/FR4) laminate subjected to fully reversed bending fatigue test is presented. Infrared thermography and acoustic emission are utilized to characterize the degradation progression. The results show similar evolutionary response indicating the presence of three degradation stages. The effect of the surface cooling on the fatigue life of the laminates is investigated both experimentally and analytically. The results show that the life of the laminate is highly dependent on the temperature and that surface cooling can significantly increase the fatigue life of the laminate. …

The purpose of this study was to investigate the multi-platform development applications MoSync, Appcelerator, and …

The (In)Visible Road Map: The Role Of Mentoring For First-Generation Black Female Doctoral Students At Predominantly White Institutions, Takea Vickers

LSU Doctoral Dissertations

Although women’s status in higher education has vastly improved over the past decades, invisible barriers remain that disenfranchise first-generation Black female doctoral students at predominantly White institutions (PWI). Specifically, the sparse literature base constricts existing knowledge and understanding about the mentoring relationships of first-generation Black female doctoral students and the barriers they face in the academy. Using the theoretical framework of intersectionality, this study sought to address the ways in which first-generation Black female doctoral students navigated the academy through mentorship and the ways in which mentoring relationships were formidable to construct. Five first-generational Black female doctoral students and two …

Examining The Boundary Conditions Between Cognitive Control And Interference Derived From Stimulus-Based And Response-Based Conflict, Jonathan D. Tall

LSU Doctoral Dissertations

Cognitive control is a broad construct that defines a set of processes involved in maintaining task goals in response to interference. Working memory capacity (WMC) is a similarly defined construct that shares many overlapping functions with cognitive control. The studies presented used controlled forms of interference to identify limits, or boundary conditions, that could help clarify the relationship between cognitive control and WMC. Experiment 1 used context effects to manipulate how interference and cognitive control could overlap. A spatial Stroop/Simon task was used in which proportion congruency for each subset (e.g., Simon or spatial Stroop) was manipulated to produce a …

The Structures, Mass Motions And Footpoints Of Solar Filaments, Aparna Venkataramanasastry

Theses and Dissertations

This thesis focuses on identifying the mechanism by which solar filaments acquire mass. Some of the speculations for how a filament gets its mass are 1) injection of mass from the chromosphere into the filament structure, and 2) condensation of mass from the corona into the region of the filament channel. Mass motion at the footpoints of the filaments is studied to detect mass entering and leaving the filament body. The magnetic properties of the footpoints of the filaments are also studied. Recommendations are drawn by comparing observational properties obtained in this study with the features used in some of …

The Combined Effects Of Copper Sulfate And Hypoxia Stress On The Swim Performance Of Bluegill Sunfish (Lepomis Macrochirus), Dustin D. Anderson

Theses and Dissertations

Copper (Cu) is a component of several aquatic pesticides often used to target noxious algae, but at high concentrations may elicit toxic effects on non-target organisms such as fish. The severity of Cu toxicity varies widely by fish species, Cu concentration, duration of exposure, and water quality. Hypoxia is a widely occurring aquatic stressor that is also a potential side effect of Cu application due to increased oxygen demand from algae decay. Because Cu and hypoxia stress may occur in concert, it is important to understand and quantify their combined effects. Critical swimming speed (Ucrit) tests are an efficient and …

Paraeducators who decide to obtain their teaching license often experience obstacles to this endeavor: money, time, family obligations, navigating the university system, and academics.

This research study examined and analyzed Minnesota paraeducators' perceptions of the barriers to obtaining their special education teaching license. It also assessed the perceptional differences between Minnesota paraeducators who have completed at least a bachelor's degree and those who have …

Restoration, Presence And Computer Use: How Computer Displays Incorporating Restorative Environments Effect Users' Sense Of Restoration And Presence, Jacob Bell

Theses and Dissertations

Recent technological advances provide opportunities for computer users to replace

desktop pictures with dynamic, audio-visual recordings. Such advances provide researchers with opportunities to better understand how specific video content may effect users' sense of restoration and presence. As described within Attention Restoration Theory, those perceiving restorative environments, which are found primarily within nature-based environments, experience a sense of restoration. Yet, prior research has largely focused on singular, and to an extent, non-interactive displays of restorative environments. The current research further investigated the restorative potential of environments having incorporated interactive, computer-based displays, with animated audio-visual environments.
