Stabilization maxillary splint therapy was employed to seat mandibular condyles in CR. Pre- and post-treatment CBCT scans were taken to compare airway changes. Thirty-one subjects (13 male and 18 female) with a mean age of 45.8 years at the time of the post-treatment scan were evaluated. DICOM files were …

The Feedforward And Feedback Controls On Gait In Adults With Diabetes, Chun-Kai Huang

Theses & Dissertations

There are nearly 26 million people with diabetes mellitus (DM) in the US, and half of chronic DMs develop somatosensory deficits due to diabetic polyneuropathy or diabetic peripheral neuropathy (DPN). The absence or impaired somatosensory feedback (e.g. touch sensation or joint proprioception) resulted from the damage of large nerve fiber, and motor deficits such as attenuated muscle strength and abnormal plantar pressure of lower extremity have been identified in DPN, and these sensorimotor impairments lead to an increased number of falls. To reduce the risk of falling, a well-coordinated and adapted limb movement driven by the feedforward (anticipatory) and feedback …

The Effects Of Thc On Attentional Bias To Emotional Stimuli, Sydney N. Haberberger

Honors Theses

The current study tested the hypothesis that the effects of THC on affect are mediated by the ability of THC to alter attentional bias to positive and negative stimuli. The study was completed by 16 participants, all of whom were consistent marijuana users. During sessions, participants used a machine called a Quantified Smoke Delivery System, which delivers a controlled amount of smoke to the user, to smoke either a cigarette that contained THC or a placebo cigarette. After smoking, participants would complete a task. During tasks, participants were placed in an eye tracking apparatus in order to record the movement …

An Examination Of Voter Groups That Make Up The Emerging Democratic Majority Thesis, Jason Waguespack

LSU New Orleans Theses and Dissertations

In 2002, John Judis and Ruy Teixeira published The Emerging Democratic Majority, a book that postulated that the United States was in the beginning of a political realignment that would spell the end of the Reagan-era coalition that gave Republicans an electoral advantage on the presidency. The authors claimed an electorate that would favor the Democratic Party would emerge to take its place. Since Senator Barack Obama’s victory in the 2008 presidential election was powered by a coalition that looked much like the one Judis and Teixeira described, it appeared the authors’ thesis was being borne out by actual …

Classification Of Breast Cancer Patients Using Somatic Mutation Profiles And Machine Learning Approaches, Suleyman Vural

Theses & Dissertations

The high degree of heterogeneity observed in breast cancers makes it very difficult to classify cancer patients into distinct clinical subgroups and consequently limits the ability to devise effective therapeutic strategies. In this study, we explore the use of gene mutation profiles to classify, characterize and predict the subgroups of breast cancers. We analyzed the whole exome sequencing data from 358 ethnically similar breast cancer patients in The Cancer Genome Atlas (TCGA) project. Identified somatic and non-synonymous single nucleotide variants were assigned a quantitative score (C-score) that represents the extent of negative impact on the function of the gene. Using …

Preventing 30-Day Readmissions Of Clostridium Difficile Patients Utilizing Targeted Discharge Instructions, Keith A. Howard

Doctor of Nursing Practice (DNP) Projects

The Patient Protection and Affordable Care Act of 2010 ushered in a new era of fiscal accountability for healthcare organizations. Healthcare organizations and providers are now jointly held responsible for the improved quality of patient care and sustained reductions in patient care events termed healthcare-acquired conditions. To ensure compliance with this newly enacted legislation, the Centers for Medicare and Medicaid Services (CMS) began penalizing hospitals for targeted conditions leading to 30-day readmissions beginning in October 2012. Annually, CMS has focused attention on conditions that endanger patient health and welfare while secondarily attempting to reduce the excessive financial expenditures in …

John Milton: Not War, Not Peace, Not Exactly Grotian, William T. Abbott

LSU New Orleans Theses and Dissertations

Foreword

This paper will be of value in answering continuing questions regarding John Milton's position on war and peace. The questions continue and are valid because Milton's works, as considered in the paper, offer support for both pro-war and pro-peace interpretations. The paper also addresses a middle-ground interpretation-that Milton's position can best be understood in light of the legal theories of Hugo Grotius, the seventeenth-century Dutch scholar who is generally accepted as the father of modern international law.

The works considered include, among others, the Nativity Ode, the sonnets, Paradise Lost, Paradise Regained, Samson Agonistes (including post 9/11 controversy involving …

LSU New Orleans Theses and Dissertations

Research on electrochemical disinfection of municipal wastewater has been conducted at the University of New Orleans using a continuous flow electrochemical reactor connected to a direct current (DC) power supply changing its polarity and varying the electrode distance. Bacterial inactivation and chlorine production were the main parameters that were recorded.

After months of research, it was determined that the electrochemical disinfection reactor is efficient and has a great potential for the future. There is no need to use chlorine and it has low operation costs.

The following design recommendations for an electrochemical disinfection unit were given:

• A detention time of …

Truth Or Consequences—Academic Physicians’ Perspective In The Management Of Commercially-Influenced Conflicts Of Interest, Melinda Lawrie Epperson

LSU New Orleans Theses and Dissertations

Since the 1990s, academic physicians have been subjected to increased requirements for disclosure in their roles as educators and researchers and for conflict of interest (COI) resolution in their financial relationships with pharmaceutical, medical device, and biotech companies, collectively referred to as industry. The requirements are the result of the convergence of federal regulations, accreditation guidelines, professional and industry codes of ethics and conduct, and institutional policies. The disclosure and COI resolution requirements are managed and resolved by a review of forms and compliance with relevant guidance documents and policies. In the context of this environmental oversight, the purpose of …

Second Lieutenant Charles Scheffel, B Company Platoon Leader, 39^th Infantry Regiment, 9^th Infantry Division modified existing methods of venereal disease control in Algeria, North Africa during Operation Torch after being ordered to reduce the venereal disease rate by his regimental commander, Colonel William Ritter. Tasked with defeating the Germans first, Scheffel learned other enemies lurked as well, and he instituted an illegal policy to solve the problem as fast and as effectively as possible. Official United States policy on the eve of World War Two prohibited the establishment and operation of a brothel. Scheffel operated this brothel as …

Fearful Temperament Moderates The Association Between Positive Parenting And Children's Social Competence During Early Childhood, Jessica M. Grande

LSU New Orleans Theses and Dissertations

Social competence during kindergarten has been linked to adaptive teacher-child and peer relationships. The quality of parents’ interaction with their children during the toddler years may promote better social development placing children on a trajectory towards social competence. Quite possibly, children vary in how responsive they are to parenting efforts. This study evaluated the extent to which positive parenting predicted change in social competence from child age 3 to 4 among 137 parent-child dyads. Observational measures of positive parenting and fearful temperament were analyzed when children were 3-years of age. Teacher reports of social competence in the classroom were collected …

Petroleum Play Study Of The Keathley Canyon, Gulf Of Mexico, Jean Pierre Malbrough

LSU New Orleans Theses and Dissertations

Beneath Keathley Canyon (KC) off the Southern Coast of Louisiana and Texas, allochthonous salt bodies have attained thicknesses of over 7620 m (25000 feet), providing excellent seals and migration pathways for hydrocarbons produced by post-rift sedimentary deposition. This study analyzes a small portion of the KC area, utilizing Petrel Seismic software and well information from the KC102 (Tiber) well.

An intra-Miocene wedge, expressed beneath salt, may provide information about movement of allochthonous salt over Wilcox sands, sediment compaction, and hydrocarbon pathways. Progradational sedimentation is the driving force which leads to faulting in the early Miocene, allowing Jurassic salt to rise, …

Emotional And Autonomic Responding To Auditory Stimuli, Jeremy C. Peres

LSU New Orleans Theses and Dissertations

Much of the research examining emotion induction, regulation, and suppression considers solely the visual modality (e.g., pictures of faces) for emotion elicitation. In reality, emotions are cued, expressed, and interpreted through multiple modalities by employing the extensive use of auditory stimuli in addition to visual stimuli. There have been some recent efforts to offset this imbalance in modality preference by using emotional auditory stimuli alone or in addition to visual stimuli. This project aims to further investigate emotional and autonomic responding to auditory stimuli with the added component of examining differential responding across social (nonlinguistic vocal expression) and non-social auditory …

Postural Responses To Perturbations Of The Vestibular System During Walking In Healthy Young And Older Adults, Jung Hung Chien

Theses & Dissertations

It has been shown that approximate one-third of US adults aged 40 years and older (69 million US citizens) have some type of vestibular problems. These declining abilities of the vestibular system affect quality of life. Difficulties in performing daily activities (dressing, bathing, getting in and out of the bed and etc.) have been highly correlated to loss of balance due to vestibular disorders. The exact number of people affected by vestibular disorders is still difficult to quantify. This might be because symptoms are difficult to describe and differences exist in the qualifying criteria within and across studies. Thus, it …

Atypical Protein Kinase C Dependent Polarized Cell Division Is Required For Myocardial Trabeculation, Derek L. Passer

Theses & Dissertations

A hallmark of cardiac development is the formation of myocardial trabeculations exclusively from the luminal surface of the primitive heart tube. Although a number of genetic defects in the endocardium (Grego-Bessa et al., 2007; Liu et al., 2010) and cardiac jelly (Camenisch et al., 2000) disrupt myocardial trabeculation, the role of cell polarity machinery in driving this process remains unclear. Herein, we demonstrate that atypical protein kinase C iota (Prkci) and its interacting partners of Par polarity complex are localized to the luminal side of luminal myocardial cells. Remarkably, a subset of these cells undergoes polarized cell division with the …

The Role Of Tumor Suppressor Co-Chaperone Chip/Stub1 In Erbb2-Mediated Oncogenesis, Haitao Luan

Theses & Dissertations

The epidermal growth factor receptor (EGFR) family member ErbB2 (Her2) is overexpressed in 20 -30% of invasive breast cancers and this overexpression correlates with poor prognosis and shorter overall as well as disease-free survival. Aberrant expression of ErbB2 through gene amplification, transcriptional deregulation and/or altered endocytic trafficking results in overexpression of ErbB2 at the plasma membrane and biases ErbB2 from primarily ligand-driven hetero-dimerization under normal expression conditions to increased ligand-independent homo-dimer and hetero-dimer formation and consequent activation. C-terminus of HSC70-Inteeracting protein (CHIP)/STIP1-homologous U-Box containing protein 1 (STUB1) is an HSP90/HSC70 interacting negative co-chaperone known to promote ubiquitination and degradation of …

The Effects Of Severe Weather Warnings On Limited English Proficient (Lep) Hispanics/Latinos In Rural Nebraska, Joan E. Nelson

Theses & Dissertations

The language barrier may severely restrict how severe weather warnings are received and responded to by Hispanics/Latinos in rural Nebraska, a state well known for frequent, volatile weather patterns. Nearly 50% of Spanish speaking Nebraskans rated their English abilities as “less than very well” (US Census Bureau, 2013). The estimated number of Hispanics/Latinos with limited English proficiency (LEP) in Nebraska equates to approximately 57,000 people. This thesis attempted to assess English ability and how severe weather warnings were received and responded to by LEP Hispanics/Latinos in rural Nebraska. This was accomplished by analysis of data from completed optional Spanish or …

There is a current gap in research on the effect BMI has on kidney transplant outcomes.

Purpose: The purpose of this study was to determine the role BMI plays in post-kidney transplant clinical outcomes including delayed graft function, new onset diabetes after transplant, wound complications, hospital length of stay, albumin, and readmissions to the hospital from initial hospitalization and at six months following kidney transplantation. The primary …

Evaluation Of The Efficiency Of And Preference For Analog Versus Mand Training On The Acquisition Of Mands For Children With Autism Spectrum Disorder, Melissa L. King

Theses & Dissertations

The present study provides a systematic replication of the Jennett, Harris, and Delmolino (2008) study comparing discrete trial instruction (DTI) and mand training on the acquisition of mands for children with autism spectrum disorder (ASD). An adapted alternating treatment design was implemented across three participants. Independent mands, variation in requested items, and duration of sessions were assessed across conditions. Generalization probes were conducted to assess generalization across communication partners (e.g., novel research assistants), along with a maintenance probe one-week post-training. Furthermore, a concurrent-chains arrangement was implemented to assess participants’ preference for teaching strategies. All participants reached mastery criterion quickest with …

Regulatory Roles Of Mical-L1 And Ehd1 In Cell Signaling And Mitosis, James B. Reinecke

Theses & Dissertations

Membrane trafficking is a basic cell biological process that controls the distribution of proteins and lipids. Our lab is particularly interested in delineating the cellular functions as well as the molecular mechanisms that regulate the C-terminal Eps15 Homology Domain (EHD) protein family of adenosine-5’-triphosphatases in mammalian cells. EHD1-4 are ubiquitously expressed in mammalian tissues and serve partially overlapping but also distinct functions in regulating membrane shaping and fission along the endocytic pathway. Specifically, EHD1 is recruited to tubular recycling endosomes (TREs) by Molecule Interacting with CasL Like-1 (MICAL-L1) and facilitates TRE fission and release of cargo from the perinuclear endocytic …

Developing And Testing An Anguilliform Robot Swimming With Theoretically High Hydrodynamic Efficiency, John B. Potts Iii

LSU New Orleans Theses and Dissertations

An anguilliform swimming robot replicating an idealized motion is a complex marine vehicle necessitating both a theoretical and experimental analysis to completely understand its propulsion characteristics. The ideal anguilliform motion within is theorized to produce ``wakeless'' swimming (Vorus, 2011), a reactive swimming technique that produces thrust by accelerations of the added mass in the vicinity of the body. The net circulation for the unsteady motion is theorized to be eliminated.

The robot was designed to replicate the desired, theoretical motion by applying control theory methods. Independent joint control was used due to hardware limitations. The fluid velocity vectors in the …

Response Of Fishes To Restoration Projects In Bayou St. John Located Within The City Of New Orleans, Louisiana, Including Hydrological Characterization And Hydrodynamic Modelling, Patrick W. Smith

LSU New Orleans Theses and Dissertations

Quantifying the impacts of restoration on coastal waterways is crucial to understanding their effectiveness. Here, I look at the impacts of multiple restoration projects on urban waterways within the city limits of New Orleans, LA, with an emphasis on the response of fishes. First I report the effects of two projects designed to improve exchange down estuary on the hydrologic characteristics of Bayou St. John (BSJ). Within BSJ, flow is dominated by subtidal wind driven processes. Removal of an outdated flood control structure did not appear to alter exchange in BSJ, but removal combined with sector gate openings did. I …

Characters Through Time, Alyssa Venezia

Honors Thesis

T. S. Eliot once wrote that we “often find that not only the best, but the most individual parts of [an author’s] work may be those in which the dead poets, his ancestors, assert their immortality most vigorously” (Eliot 37). By focusing on character adaptations, one comes to understand how authors of children’s books are able to adapt classic literature into age-appropriate texts that retain the merits of the original. Five sets of characters shall be analyzed to demonstrate the success of the adaptations presented in children’s literature. In the first, Sir Bedivere from Sir Thomas Malory’s Le Morte Darthur …

Correction Of Verication Bias Using Log-Linear Models For A Single Binaryscale Diagnostic Tests, Haresh Rochani, Hani M. Samawi, Robert L. Vogel, Jingjing Yin

Biostatistics: Faculty Publications

In diagnostic medicine, the test that determines the true disease status without an error is referred to as the gold standard. Even when a gold standard exists, it is extremely difficult to verify each patient due to the issues of costeffectiveness and invasive nature of the procedures. In practice some of the patients with test results are not selected for verification of the disease status which results in verification bias for diagnostic tests. The ability of the diagnostic test to correctly identify the patients with and without the disease can be evaluated by measures such as sensitivity, specificity and predictive …
