Behavioral Health Professionals’ Perception Of Anxiety Disorders Amongst African American Clients, Chantel K. Gant

LSU New Orleans Theses and Dissertations

Abstract

Anxiety disorders are frequent and increasing across the United States including for ethnically diverse populations (Carter et al., 2012). There is a need for education in the community on anxiety disorders about indicators of anxiety, severity and therapeutic approaches that would be beneficial (Johnson & Coles, 2013). It is imperative to know the variation in anxiety for African Americans to aid in therapeutic resources and counseling designed for this population (Hopkins & Shook, 2017). Prior research includes more of a focus on behavioral health professionals’ perspectives in conjectural situations rather than actual clinical practice (Joy & Bartholomew, 2021; Lawrence …

Modification, Transport, And Sources Of Hydrocarbon Oxidation Products From Groundwater At Crude Oil And Diesel Spill Sites In Minnesota: Unveiling Common “Theems” Via Spectroscopy & Chromatography, Eduardo E. Turcios Valle

LSU New Orleans Theses and Dissertations

In this thesis, petroleum-contaminated groundwater from three spill-affected Minnesota sites—two contaminated with crude oil; one with diesel—is investigated to elucidate whether differences in degradation products from different parent oils exist. After spill events, parent molecules from the leaked oil seep underground and undergo microbial degradation over time, transforming into hydrocarbon oxidation products (HOPs), water-soluble contaminants that infiltrate groundwater aquifers, flowing into nearby environments and towns while exhibiting environmental persistence, toxicity to aquatic biota, and potential risks to humans that become exposed. Spectroscopic and chromatographic study of the structural themes and spatial distributions of HOPs reveals preferential degradation of aliphatic (biolabile) …

The Slidell Museum: Rebuilding Overlooked And Disregarded Narratives In Small-Town America, Gregory D. Scott

LSU New Orleans Theses and Dissertations

The community of Slidell, Louisiana, sits across the lake from New Orleans on the north shore of Lake Pontchartrain. Slidell quietly shrouds a multitude of fascinating historic narratives with roots that extend back to before the 1718 founding of New Orleans. The first documented European presence in the area near Slidell occurred in 1699 when Iberville camped at Goose Point a few miles west of present-day Slidell. This area would play a vital role in the survival, growth, and development of the early New Orleans settlement.

Slidell has a rich history of people, places, and events. In 2005, the devastation …

Topography-Based Modulation Of Environmental Factors As A Mechanism For Intertidal Microhabitat Formation: A Basis For Marine Ecological Design, Franz Bauer, Antony M. Knights, Mick E. Hanley, John N. Griffin, Andy Foggo, Austin Brown, Louise B. Firth

School of Biological and Marine Sciences

Topographic complexity is often considered to be closely associated with habitat complexity and niche diversity; however, complex topography per se does not imply habitat suitability. Rather, ecologically suitable habitats may emerge if topographic features interact with environmental factors and thereby alter their surrounding microenvironment to the benefit of local organisms (e.g., resource provisioning, stress mitigation). Topography may thus act as a key modulator of abiotic stressors and biotic pressures, particularly in environmentally challenging intertidal systems. Here, we review how topography can alter microhabitat conditions with respect to four resources required by intertidal organisms: a source of energy (light, suspended food …

Archives Of Facade, Arielle Nord

Masters Theses and Doctoral Dissertations

Fantasy is a genre that seldom includes black characters. When black characters are present, they often lack the same narrative significance, reliability and character growth that is given to white characters. This can lead to poorly written black characters that lack purpose or fall victim to stereotypical roles and troupes. Depicting black characters in this way can further isolate readers who wish to read about black characters, that are more than just stereotypes, within the fantasy genre. This thesis will examine the writing techniques of character coding and the subversion of stereotypes and how they present a way for black …

Click, Click, Boom: A Multi-Level Analysis Of Repeat Firearm Offending In Chattanooga, Tennessee, Katlyn Whittenburg

Masters Theses and Doctoral Dissertations

Criminologists have long noted the exacerbated rates of firearm-related offending in the United States in comparison to other developed nations. There has been a renewed focus on gun crime in the wake of a recent dramatic reversal of the long-trending decrease in firearm-related violence. Explorations of the factors that contribute to firearm offending are often restricted to large metro areas like Chicago, New York City, and Philadelphia—which may have limited generalizability to more common small and medium sized cities in the United States. This study attempts to address this concern through examination of the factors that contribute to firearm re-offending …

Understanding The Importance Of Peak Bone Mass, Timothy Hereford, Alec Kellish, Julie Balch Samora, Louise Reid Nichols

Department of Medicine Faculty Papers

Bone mass attained early in life is one of the most important determinants of lifelong skeletal health. Bone mineral content increases exponentially during childhood. In fact, 40%-60% of the total adult bone mass is accrued during puberty. By the end of the first 2 decades of life, peak bone mass has been reached. Between ages 20-50, bone mass has plateaued, but it continues to remodel. This is regulated by parathyroid hormone (PTH), vitamin D3, and insulin-like growth factor 1 (IGF-1). After the age of 50, bone mass begins to decrease. The purpose of this paper is to review the importance …

Research outputs 2022 to 2026

STUDY QUESTION: Do embryos displaying abnormal cleavage (ABNCL) up to Day 3 have compromised live birth rates and neonatal outcomes if full blastulation has been achieved prior to transfer? SUMMARY ANSWER: ABNCL is associated with reduced full blastulation rates but does not impact live birth rates and neonatal outcomes once full blastulation has been achieved. WHAT IS KNOWN ALREADY?: It is widely accepted that ABNCL is associated with reduced implantation rates of embryos when transferred at the cleavage stage. However, evidence is scarce in the literature reporting birth outcomes from blastocysts arising from ABNCL embryos, likely because they are ranked …

Intensity-Dependent Effects Of Tdcs On Motor Learning Are Related To Dopamine, Li Ann Leow, Jiaqin Jiang, Samantha Bowers, Yuhan Zhang, Paul E. Dux, Hannah L. Filmer

Research outputs 2022 to 2026

Non-invasive brain stimulation techniques, such as transcranial direct current stimulation (tDCS), are popular methods for inducing neuroplastic changes to alter cognition and behaviour. One challenge for the field is to optimise stimulation protocols to maximise benefits. For this to happen, we need a better understanding of how stimulation modulates cortical functioning/behaviour. To date, there is increasing evidence for a dose-response relationship between tDCS and brain excitability, however how this relates to behaviour is not well understood. Even less is known about the neurochemical mechanisms which may drive the dose-response relationship between stimulation intensities and behaviour. Here, we examine the effect …
