The Interaction Of Post-Partum Depression And Maternal Knowledge Of Infant Development On Change In Sensitive And Responsive Parenting During Early Infancy, Julie Weiss

LSU New Orleans Theses and Dissertations

Sensitive and responsive parenting during early infancy is highly understudied, particularly in families with a low socioeconomic status. Longitudinal data from 41 mothers and their 4 to 16 week old infants found that accurate maternal knowledge of infant development positively affected parenting contemporaneously and over time while depression did not affect parenting in this sample. Implications for intervention and research are discussed.

Wave Transformation At A Saltmarsh Edge And Resulting Marsh Edge Erosion: Observations And Modeling, Kevin J. Trosclair

LSU New Orleans Theses and Dissertations

This study examines wind generated waves during winter storms, their transformation/attenuation near the marsh edge, and the resulting saltmarsh edge erosion. A simple numerical model for wave generation, transmission and marsh edge erosion was developed and validated against observations from Lake Borgne, Louisiana. Results suggest that meteorological conditions modify the local water depth via wind or wave setup and atmospheric pressure, thus exerting a first order control on the location of wave attack, which in turn determines the type of wave forces (shear vs. impact) that dominate the erosion process. Scarp failure follows, at a location determined by water level, …

LSU New Orleans Theses and Dissertations

Philosophical tenets have been at the heart of the counseling process since its inception. This study explores the factors present within a graduate-level counseling class that directly teaches these philosophical foundations through an exploration of dialectics and its impact on the medium of conversation. Interviews were conducted with both the professor that created the class as well as its current instructor along with focus groups of both current program students and program alumni. The fundamental aim was to understand the processes at work within the class and their influence on its students. The results suggest that by bringing the students …

Semantic Services For Enterprise Data Exchange, James A. Sauvinet

LSU New Orleans Theses and Dissertations

Data exchange between different information systems is a complex issue. Each system, designed for a specific purpose, is defined using a vocabulary of the specific business. While Web services allow interoperations and data communications between multiple systems, the clients of the services must understand the vocabulary of the targeting data resources to select services or to construct queries. In this thesis we explore an ontology-based approach to facilitate clients’ queries in the vocabulary of the clients’ own domain, and to automate the query processing. A governmental inter-department data query process has been used to illustrate the capability of the semantic …

Curated Reasoning By Formal Modeling Of Provenance, Kevin B. Shaw

LSU New Orleans Theses and Dissertations

The core problem addressed in this research is the current lack of an ability to repurpose and curate scientific data among interdisciplinary scientists within a research enterprise environment. Explosive growth in sensor technology as well as the cost of collecting ocean data and airborne measurements has allowed for exponential increases in scientific data collection as well as substantial enterprise resources required for data collection. There is currently no framework for efficiently curating this scientific data for repurposing or intergenerational use.

There are several reasons why this problem has eluded solution to date to include the competitive requirements for funding and …

A Wedge Impact Theory Used To Predict Bow Slamming Forces, Ashok Benjamin Basil Attumaly

LSU New Orleans Theses and Dissertations

The pressures and impact forces acting on a hull while experiencing bow wave slamming is analyzed using Vorus' Impact Theory. The theory extends the hydrodynamic analysis of planing hulls from simple wedges to irregular shapes using a Boundary Element Method. A Fortran-based code developed by the Author is used to analyze hullforms. Linear strip theory is used to extend the analysis over a three dimensional hull. Post-processing of output data gives hull pressure distributions at different time steps and is visually presentable.

The PSSE dynamics simulator is used to study the dynamics of the IEEE 39 Bus equivalent test system. To correlate dynamic behavior to system voltage abnormality, this research utilizes two different pattern recognition methods one being algorithmic method known as …

Hurricane-Exposed Youth And Psychological Distress: An Examination Of The Role Of Social Support, Donice M. Banks

LSU New Orleans Theses and Dissertations

Hurricane exposure places youth at risk for psychological distress such as symptoms of Posttraumatic Stress Disorder (PTSD), anxiety, and depression, while social support may contribute to resilience following disasters. This study examined associations among family and peer social support, level of hurricane exposure, and psychological distress using both a large single-time assessment sample (N = 1098) and a longitudinal sample followed over a six-month period (n = 192). Higher levels of hurricane exposure were related to lower levels of social support from family and peers as well as to higher levels of psychological distress. Higher levels of family …

Assessing Risk In Adolescent Offenders: A Comparison Of Risk Profiles Versus Summed Risk Factors, Katherine A. Gottlieb

LSU New Orleans Theses and Dissertations

Research supports interventions for high-risk juvenile offenders to reduce recidivism. Methods for assessing delinquent risk vary, however. Aggregate risk scores (i.e. number of risk factors) and specific risk profiles (i.e. types of risk factors) are both empirically supported techniques. This study compared aggregate scores versus profiles for predicting measures of criminal severity among detained adolescents (n=292). Twenty-four risk factors from the Structured Assessment of Violence Risk in Youth (SAVRY) were summed to calculate aggregate scores. Using latent class analysis (LCA), profiles were identified based on scores from the following theoretically important SAVRY risk factors: Risk Taking/Impulsivity, Anger Management …

Special Education Co-Teachers' Perceptions: Collaboration, Involvement In Instruction, And Satisfaction, Eden Hagelman

LSU New Orleans Theses and Dissertations

Co-teaching is an approach that is frequently used by schools when students both with and without disabilities are taught in an inclusive classroom. With co-teaching, a general education teacher and a special education teacher share the responsibility of planning and teaching students. This study examined the perceptions of elementary special education co-teachers (n=81) regarding their collaboration with the general educator and their involvement in instruction in the inclusive classroom. In addition, the special education teachers' satisfaction with the co-teaching assignment was investigated. Findings showed that special education co-teachers shared an average of 30 minutes of co-planning a week, teachers who …

Sistas On The Move: An Ethnographic Case Study Of Health And Friendship In Urban Space Among Black Women In New Orleans, Valerie A. Mcmillan

LSU New Orleans Theses and Dissertations

Abstract

Black women are disproportionately affected by adverse health conditions, such as obesity and heart disease. For example, more black women currently die from complications associated with diabetes, obesity and high blood pressure than any other ethnic group in the United States (Gourdine 2011). There are however, increasing numbers of everyday black women who defy these statistics and are positive role models for all women. One such group of women is the New Orleans chapter of Sistas On The Move (SOTM), an all-female running group that emphasizes the importance of black women’s health and builds community around physical activity. Through …

Knights, Dudes, And Shadow Steeds: Late Victorian Culture And The Early Cycling Clubs Of New Orleans, 1881-1891, Lacar E. Musgrove

LSU New Orleans Theses and Dissertations

In the 1880s, two cycling clubs formed in New Orleans—the New Orleans Bicycle Club in 1881 and the Louisiana Cycling Club in 1887. These clubs were institutions of Victorian middle class culture that, like other athletic clubs, arose from the conditions of urban modernity and Victorian class anxieties. The NOBC, like other American cycling clubs, conformed to Victorian values of order and respectability. The attitudes and activities of the LCC, whose membership was younger, reflected instead a counter-Victorian ethos. This paper examines these two clubs in the context of late Victorian culture in New Orleans as it responded both to …

Experimental Investigation Of Mist Film Cooling And Feasibility Study Of Mist Transport In Gas Turbines, Reda M. Ragab

LSU New Orleans Theses and Dissertations

In the modern advanced gas turbines, the turbine inlet temperature may exceed 1500°C as a requirement to increase power output and thermal efficiency. Therefore, it is imperative that the blades and vanes are cooled so they can withstand these extreme temperatures. Film cooling is a cooling technique widely used in high-performance gas turbines. However, the film cooling effectiveness has almost reached plateau, resulting in a bottleneck for continuous improvement of gas turbines' efficiency.

In this study, an innovative cooling scheme, mist film cooling is investigated through experiments. A small amount of tiny water droplets with an average diameter about 10-15 …

A Numerical Study Of High Temperature And High Velocity Gaseous Hydrogen Flow In A Cooling Channel Of A Ntr Core, Sajan B. Singh

LSU New Orleans Theses and Dissertations

Two mathematical models (a one and a three-dimensional) were adopted to study, numerically, the thermal hydrodynamic behavior of flow inside a single cooling channel of a Nuclear Thermal Rocket (NTR) engine. The first model assumes the flow in the cooling channel to be one-dimensional, unsteady, compressible, turbulent, and subsonic. The working fluid (GH₂) is assumed to be compressible. The governing equations of the 1-D model are discretized using a second order accurate finite difference scheme. Also, a commercial CFD code is used to study the same problem. Numerical experiments, using both codes, simulated the flow and heat transfer …
