Reciprocal Peer Mentoring : Increasing The Prosocial Behavior Of Socially Neglected Students, Tai A. Collins Jan 2013

Reciprocal Peer Mentoring : Increasing The Prosocial Behavior Of Socially Neglected Students, Tai A. Collins

LSU Doctoral Dissertations

Two studies investigated the effectiveness of the Reciprocal Peer Mentoring intervention in improving the prosocial behavior of socially neglected elementary school students as measured by a Direct Behavior Rating filled out by their teachers. Reciprocal Peer Mentoring uses the methodological framework of the Check-In/Check-Out intervention (e.g. Hawken & Horner, 2003), but expands on it by using peers as mentors, adding a reciprocity component, focusing on prosocial behavior, and targeting socially neglected students. In Study 1, the effectiveness of Nonreciprocal Peer Mentoring was examined, as popular peers served as mentors for neglected peers. In Study 2, neglected or rejected students mentored …

Postmodern Humanism And The "Exhaustion Of Easy Life", Mason Beets Jan 2013

Postmodern Humanism And The "Exhaustion Of Easy Life", Mason Beets

Dissertations and Theses @ UNI

The twenty-first century appears to herald a new epoch, one in which religion and other similar belief systems appear to have run their course. However, this should not necessarily mean that other forms of spirituality and interconnectedness must fade away. Within America, there is a humanistic undercurrent that is gaining strength within our postmodern condition, even as we begin to challenge several of the tenets of postmodernity itself. The groundswell of American humanism has a notable and wholly unintended effect: it ideologically rehabilitates modes or vehicles of thought that might otherwise be labeled as defunct, or inapplicable to the changing …

Bcl9 And C9orf5 Are Associated With Negative Symptoms In Schizophrenia: Meta-Analysis Of Two Genome-Wide Association Studies, Chun Xu, Nagesh Aragam, Xia Li, Erika Cynthia Villa, Liang Wang, David Briones, Brenda Bin Su, Michael A. Escamilla, Kesheng Wang

Health & Biomedical Sciences Faculty Publications

Schizophrenia is a chronic and debilitating psychiatric condition affecting slightly more than 1% of the population worldwide and it is a multifactorial disorder with a high degree of heritability (80%) based on family and twin studies. Increasing lines of evidence suggest intermediate phenotypes/endophenotypes are more associated with causes of the disease and are less genetically complex than the broader disease spectrum. Negative symptoms in schizophrenia are attractive intermediate phenotypes based on their clinical and treatment response features. Therefore, our objective was to identify genetic variants underlying the negative symptoms of schizophrenia by analyzing two genome-wide association (GWA) data sets consisting …

Framework Of Damage Detection In Vehicle-Bridge Coupled System And Application To Bridge Scour Monitoring, Xuan Kong Jan 2013

Framework Of Damage Detection In Vehicle-Bridge Coupled System And Application To Bridge Scour Monitoring, Xuan Kong

LSU Doctoral Dissertations

Most vibration-based damage identification methods make use of measurements directly from bridge structures with attached sensors. However, the vehicle moving on the bridge can serve as both an active actuator and a response receiver. This dissertation aimed to develop new methodologies to eventually detect bridge damages such as scour using the dynamic response of the vehicle. To reach the final objective, a framework of damage identification was developed first, which gave a guideline on the three crucial steps for damage detection. An optimization method was proposed that combines the Genetic Algorithm (GA) and the First Order (FO) method. It has …

Microstructure And Physics-Based Structural Models For Suspended Clay-Exopolymer Flocs, Xiaoling Tan Jan 2013

Microstructure And Physics-Based Structural Models For Suspended Clay-Exopolymer Flocs, Xiaoling Tan

LSU Doctoral Dissertations

Costal or shoreline waters are often characterized by high concentrations of suspended cohesive sediments (or clay) affected by varied organic matters (mostly extracellular polymeric substances or exopolymers), salt, and hydrodynamic disturbance. Resulting from the flocculation-disaggregation between the colloidal clay and exopolymer, the size and structure changes of the cohesive sediments are of key importance for understanding sediment transport processes (i.e., settling, breakage, and survivability) and the geotechnical and geophysical properties of the bottom bed. Because the coastal environment is extremely complicated, with many unpredictable and uncontrollable parameters, current knowledge is still insufficient to predict or fully explain the behavior of …

Earth Occultation Imaging Of The Low Energy Gamma-Ray Sky With The Fermi/Gamma-Ray Burst Monitor, James Craig Rodi Jan 2013

Earth Occultation Imaging Of The Low Energy Gamma-Ray Sky With The Fermi/Gamma-Ray Burst Monitor, James Craig Rodi

LSU Doctoral Dissertations

The hard X-ray/soft gamma-ray sky is highly variable as source intensities can vary on timescales from fractions of a second to years. The type of sources emitting at these energies often include compact objects such as white dwarfs, neutron stars, and black holes interacting with the surrounding environment, which enables the study of the properties and characteristics of these exotic objects. Because the interactions with the environment is often through accretion, most of the emission is in X-rays and gamma-rays Frank et al. 1992 making this energy range critical to understanding the relevant physical processes and mechanisms. Hard X-ray/soft gamma-ray …

Essays On Credit Default Swaps And Debtor-Creditor Relationships, Cihan Uzmanoglu Jan 2013

Essays On Credit Default Swaps And Debtor-Creditor Relationships, Cihan Uzmanoglu

LSU Doctoral Dissertations

Over the last decade, markets for credit insurance have developed dramatically and credit default swaps (CDS) have become the instrument of choice when it comes to hedging credit risks. The expanded hedging opportunities CDS provide and the allied benefits of better risk-sharing notwithstanding, concerns over the economic role of CDS arise from their ability to engender “empty” creditors – joint holders of the bond and CDS, and the role such creditors play in distress situations. Financially distressed firms often restructure their debt through out-of-court renegotiations with creditors to avoid formal default. In addition to the going concern value of the …

High Capacity Digital Beam Steering Technology, Daniel James Hebert Jan 2013

High Capacity Digital Beam Steering Technology, Daniel James Hebert

LSU Doctoral Dissertations

A novel method is described in detail for steering light in many directions without moving mechanical parts. The method involves a combination of liquid crystal cells and polarizing beam splitters. The polarization at each beam splitter is controlled by applying a signal to its corresponding liquid crystal cell. A study of light steering techniques is described for efficient beam placement, in a line and plane. These techniques permit accurate, non-mechanical, beam steering limited by the response time of the liquid crystal cells. A theoretical limit to the number of discrete directions is described and closely approached for a one dimensional …

Geometric Modeling And Optimization Over Regular Domains For Graphics And Visual Computing, Shenghua Wan Jan 2013

Geometric Modeling And Optimization Over Regular Domains For Graphics And Visual Computing, Shenghua Wan

LSU Doctoral Dissertations

The effective construction of parametric representation of complicated geometric objects can facilitate many design, analysis, and simulation tasks in Computer-Aided Design (CAD), Computer-Aided Manufacturing (CAM), and Computer-Aided Engineering (CAE). Given a 3D shape, the procedure of finding such a parametric representation upon a canonical domain is called geometric parameterization. Regular geometric regions, such as polycubes and spheres, are desirable domains for parameterization. Parametric representations defined upon regular geometric domains have many desirable mathematical properties and can facilitate or simplify various surface/solid modeling and processing computation. This dissertation studies the construction of parameterization on regular geometric domains and explores their applications …

Large Deviations For Stochastic Navier-Stokes Equations With Nonlinear Viscosities, Ming Tao Jan 2013

Large Deviations For Stochastic Navier-Stokes Equations With Nonlinear Viscosities, Ming Tao

LSU Doctoral Dissertations

In this work, a Wentzell-Freidlin type large deviation principle is established for the two-dimensional stochastic Navier-Stokes equations (SNSE's) with nonlinear viscosities. We fi_x000C_rst prove the existence and uniqueness of solutions to the two-dimensionalstochastic Navier-Stokes equations with nonlinear viscosities using the martingale problem argument and the method of monotonicity. By the results of Varadhan and Bryc, the large deviation principle (LDP) is equivalent to the Laplace-Varadhan principle (LVP) if the underlying space is Polish. Then using the stochastic control and weak convergence approach developed by Budhiraja and Dupuis, the Laplace-Varadhan principle for solutions of stochastic Navier-Stokesequations is obtained in appropriate function …

Resolving Pronominal Anaphora Using Commonsense Knowledge, Seyedeh Leili Javadpour Jan 2013

Resolving Pronominal Anaphora Using Commonsense Knowledge, Seyedeh Leili Javadpour

LSU Doctoral Dissertations

Coreference resolution is the task of resolving all expressions in a text that refer to the same entity. Such expressions are often used in writing and speech as shortcuts to avoid repetition. The most frequent form of coreference is the anaphor. To resolve anaphora not only grammatical and syntactical strategies are required, but also semantic approaches should be taken into consideration. This dissertation presents a framework for automatically resolving pronominal anaphora by integrating recent findings from the field of linguistics with new semantic features. Commonsense knowledge is the routine knowledge people have of the everyday world. Because such knowledge is …

Time Of Day Preferences And Resource Allocation, Alicia Marie Briganti Jan 2013

Time Of Day Preferences And Resource Allocation, Alicia Marie Briganti

LSU Doctoral Dissertations

Previous studies have shown that circadian rhythms can have a significant impact on cognitive task performance (Bodenhausen, 1990; May, Hasher, & Stoltzfus, 1993), and that performance is better during participants’ optimal time of day for explicit memory tasks and for tasks where inhibition of responses is required. Researchers have concluded that deficits during one’s non-optimal time of day are due to inefficient inhibition (e.g., May & Hasher, 1998). However, previous studies have not sufficiently addressed possible changes in resource allocation, or the amount of resources that are allocated to the primary task versus the amount of resources used to actively …

Topology And Shape Optimization Of Hydrodynamically–Lubricated Bearings For Enhanced Load-Carrying Capacity, Mohammad Fesanghary Jan 2013

Topology And Shape Optimization Of Hydrodynamically–Lubricated Bearings For Enhanced Load-Carrying Capacity, Mohammad Fesanghary

LSU Doctoral Dissertations

Bearings are basic and essential components of nearly all machinery. They must be designed to work under different loads, speeds, and environments. Of all the performance parameters, load-carrying capacity (LCC) is often the most crucial design constraint. The objective of this research is to investigate different design methodologies that significantly improve the LCC of liquid-lubricated bearings. This goal can be achieved by either altering the surface texture or the bearing geometrical configuration. The methodology used here is based on mathematical topological/shape optimization algorithms. These methods can effectively improve the design performance while avoiding time-consuming trial-and-error design techniques. The first category …

Modeling, Numerical Analysis, And Predictions For The Detonation Of Multi-Component Energetic Solids, Michael Wayne Crochet Jan 2013

Modeling, Numerical Analysis, And Predictions For The Detonation Of Multi-Component Energetic Solids, Michael Wayne Crochet

LSU Doctoral Dissertations

Metal powders are often used as an additive to conventional high explosives to enhance the post-detonation blast wave. Piston-impact simulations are commonly utilized to predict performance metrics such as detonation speed and strength, as well as assessing the impact and shock sensitivity of these materials. The system response is strongly influenced by the initial particle size distribution and material composition. Multiphase continuum models have been routinely applied at the macroscale to characterize the detonation of solid high explosives over engineering length scales. Current models lack a description of the physically permissible constitutive relations for mass transfer due to general chemical …

Geodatabase-Assisted Storm Surge Modeling, Sait Ahmet Binselam Jan 2013

Geodatabase-Assisted Storm Surge Modeling, Sait Ahmet Binselam

LSU Doctoral Dissertations

Tropical cyclone-generated storm surge frequently causes catastrophic damage in communities along the Gulf of Mexico. The prediction of landfalling or hypothetical storm surge magnitudes in U.S. Gulf Coast regions remains problematic, in part, because of the dearth of historic event parameter data, including accurate records of storm surge magnitude (elevation) at locations along the coast from hurricanes. While detailed historical records exist that describe hurricane tracks, these data have rarely been correlated with the resulting storm surge, limiting our ability to make statistical inferences, which are needed to fully understand the vulnerability of the U.S. Gulf Coast to hurricane-induced storm …

An Alu Element-Based Model Of Human Genome Instability, George Wyndham Cook, Jr. Jan 2013

An Alu Element-Based Model Of Human Genome Instability, George Wyndham Cook, Jr.

LSU Doctoral Dissertations

The human genome is strewn with repetitive sequence. An early estimate derived from the draft human genome sequence placed this repetitive content at ~45%. More detailed recent analyses have advanced the idea that the human repetitive and repeat derived contribution to the genome may be closer to 66-69%. The most commonly repeated sequence in the human genome is the Alu element. Alus make up 10.6 percent of all human DNA and have expanded to over one million copies in the human genome reproducing through a copy and paste mechanism. New Alu germline insertions are estimated to occur at a rate …

Study On The Performance Of Tcp Over 10gbps High Speed Networks, Cheng Cui Jan 2013

Study On The Performance Of Tcp Over 10gbps High Speed Networks, Cheng Cui

LSU Doctoral Dissertations

Internet traffic is expected to grow phenomenally over the next five to ten years. To cope with such large traffic volumes, high-speed networks are expected to scale to capacities of terabits-per-second and beyond. Increasing the role of optics for packet forwarding and transmission inside the high-speed networks seems to be the most promising way to accomplish this capacity scaling. Unfortunately, unlike electronic memory, it remains a formidable challenge to build even a few dozen packets of integrated all-optical buffers. On the other hand, many high-speed networks depend on the TCP/IP protocol for reliability which is typically implemented in software and …

Poultry Litter Ash As A Phosphorus Source For Greenhouse Crop Production, Daniel Evan Wells Jan 2013

Poultry Litter Ash As A Phosphorus Source For Greenhouse Crop Production, Daniel Evan Wells

LSU Doctoral Dissertations

Phosphorus (P) is an essential nutrient for all life forms, including plants, but is a limited agricultural resource whose future availability is in question. Therefore, identification of alternative forms of P fertilizers is important. Poultry litter ash (PLA), a byproduct of bioenergy production, contains high concentrations of P comparable to conventional fertilizers. Forms of P contained in PLA have been characterized as having low water solubility. Nutrient losses during containerized plant production are high due to excessive inputs of water and nutrients and low nutrient sorption capacities of common horticultural substrate components. Environmental concerns over reduced water quality intensify this …
