Psychopathology In Person With And Without Co-Morbid Autism, Martin Nicholas Ancona Jan 2009

Psychopathology In Person With And Without Co-Morbid Autism, Martin Nicholas Ancona

LSU Doctoral Dissertations

Autism and intellectual disability are frequently co-occurring. In addition, a diagnosis of mild, moderate, severe, or profound intellectual disability increases the risk for co-occurring Axis I psychiatric disorders. This study utilized multivariate analyses of variance (MANOVA) to determine whether mean differences exist across three diagnostic groups: ID only, ID and autism, and ID and pervasive developmental disorder not otherwise specified (PDD-NOS) on the linear combination of subscales present on the Diagnostic Assessment of the Severely Handicapped-II (DASH-II), a psychometrically sound measure that assesses psychopathology in those with ID. The results of this study supported an association between the presence of …

Particle-Chemical Interactions And Environmental Chemodynamics Of Fine And Ultrafine Particles In A Natural Disaster Scenario, Nicholas A. Ashley Jan 2009

Particle-Chemical Interactions And Environmental Chemodynamics Of Fine And Ultrafine Particles In A Natural Disaster Scenario, Nicholas A. Ashley

LSU Doctoral Dissertations

The interactions of fine and ultrafine particles with chemicals play a dominant role in determining the mobility and availability of pollutants in the environment. Fine particles in sediments can sequester chemicals from the water column, and release volatile and semi-volatile organic compounds to the gas phase upon exposure to air. Ultrafine particles which are photoreactive can degrade these vapor-phase contaminants, and may transform the molecules into species which are more toxic or hazardous than the parent. As the widespread, commercial use of ultrafine particles becomes more common, understanding the chemodynamics of these particles and their interactions with chemicals in the …

Children Of Men: The American Jeremiad In Twentieth And Twenty-First Century Science Fiction And Film, Joseph Franklin Brown Jr.

LSU Doctoral Dissertations

This dissertation considers the dynamic and resilient influence of the jeremiad, an early American religious and literary mode, on contemporary American literature and culture. It argues that the polemical, dystopian, and apocalyptic narratives so abundant in twentieth-century literature and film participate in an ingrained literary tradition that accounts for society's misfortunes as penalty for its social and moral evils while, at the same time, emphasizing an American exceptionalism born out of a belief in the society's election through its covenant with God. The project makes connections between early-American texts and related works of twentieth and twenty-first century American literature and …


Effects Of Clenbuterol On Skeletal And Cardiac Muscle In Horses, Jessica Thompson Jan 2009

Effects Of Clenbuterol On Skeletal And Cardiac Muscle In Horses, Jessica Thompson

LSU Master's Theses

Clenbuterol is a commonly prescribed β2-adrenergic agonist approved for veterinary use as a bronchodilator in horses with reactive and obstructive airway disease. Potential for abuse of this drug in the horse industry is substantial, due to the perceptions that clenbuterol increases performance and lean muscle mass. Although anabolic effects have been confirmed in multiple species, recent studies into the effects of clenbuterol in exercising horses suggest that clenbuterol doses within therapeutic ranges negatively impact aerobic capacity and cardiac function. Results of studies in murine models demonstrate that clenbuterol directly induces skeletal and cardiac muscle cell death at high doses. Three …

The Effects Of Performance Feedback Plus Graphing On The Treatment Integrity Of A Parent Implemented Reading Intervention Program, Lacey Leblanc

LSU Doctoral Dissertations

Repeated reading is an effective intervention that has been demonstrated to remediate reading problems in children. The parent tutoring literature has shown that this intervention is effective in the home environment as well as the school environment. One primary difference between home-based and school-based interventions is that a consultant is often available to work with teachers, whereas parents are not always offered this resource. However, research has demonstrated that behavioral consultation in the home environment, in which a parent serves the role of the consultee, is an effective method for addressing academic concerns. In order to make sound conclusions regarding …


Proxy Records Of Paleohurricanes For The Western And Southern Caribbean, Terrence Allen Mccloskey Jan 2009

Proxy Records Of Paleohurricanes For The Western And Southern Caribbean, Terrence Allen Mccloskey

LSU Doctoral Dissertations

This dissertation evaluates the hypothesis that hurricane activity levels in the North Atlantic during the late Holocene have been driven by latitudinal movements of the North Atlantic circulation system. Multi-millennial sedimentary proxy records, based on the occurrence of overwash clastic layers, provide clear evidence of abruptly alternating periods of hurricane landfall frequency for Nicaragua and Belize. Three Belizean transects exhibit an Active period (hyperactivity) occurring from ~2000-6000 cal yr BP, although dating is inconsistent across the transects. An Active period covering the last 500 years is found at one location. The Nicaraguan record, derived from three transects covering >90 km …

Materials and Methods: Intact cartilage cores with underlying subchondral bone were collected aseptically from both humeral heads of 16 fresh canine cadavers. Joints from each dog were randomly assigned to SI or SR. Ten osteochondral …


Comorbid Psychopathology In Individuals With Autism Spectrum Disorders And Intellectual Disabilities, Santino Vincent Lovullo Jan 2009

Comorbid Psychopathology In Individuals With Autism Spectrum Disorders And Intellectual Disabilities, Santino Vincent Lovullo

LSU Master's Theses

While there has been an abundance of research investigating Autism Spectrum Disorders (ASD) in children, very little emphasis has been placed on ASD in adults, especially in regards to comorbid psychopathology. This is of great concern considering that ASD often co-occurs with intellectual disability (ID), and that both may serve as risk factors for additional psychopathology. While instruments exist that measure comorbid psychopathology in adults with ID, these scales are not targeted to the unique expression of comorbidity in adults with ID and ASD. The Autism Spectrum Disorders-Comorbidity for Adults (ASD-CA) was devised for this reason. This paper begins with …

Atom-Based Computer Simulation Studies Of Gas-To-Liquid Nucleation In Atmospherically Relevant Systems: Clarifying Discrepancies And Elucidating Mechanisms, Ricky Bendanillo Nellas

LSU Doctoral Dissertations

For over a century, nucleation for all systems was thought simplistically to be a process that advances through the formation of critical clusters with a well-defined composition. Our results show intriguing nucleation mechanisms that challenge the aforementioned notion. We employed the simple TraPPE-UA (transferable potential for phase equilibria – united atom) force field and the AVUS-HR approach (a combination of aggregation-volume-bias Monte Carlo, umbrella sampling, and histogram reweighting), to investigate the homogeneous vapor-to-liquid nucleation of various nucleating systems. We found out that these systems could nucleate through a variety of unique non-ideal mechanisms. Alongside existing experimental investigations, this dissertation presents …
