Network Analysis Of Circular Permutations In Multidomain Proteins Reveals Functional Linkages For Uncharacterized Proteins., Donald Adjeroh, Yue Jiang, Bing-Hua Jiang, Jie Lin Jan 2014

Network Analysis Of Circular Permutations In Multidomain Proteins Reveals Functional Linkages For Uncharacterized Proteins., Donald Adjeroh, Yue Jiang, Bing-Hua Jiang, Jie Lin

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Various studies have implicated different multidomain proteins in cancer. However, there has been little or no detailed study on the role of circular multidomain proteins in the general problem of cancer or on specific cancer types. This work represents an initial attempt at investigating the potential for predicting linkages between known cancer-associated proteins with uncharacterized or hypothetical multidomain proteins, based primarily on circular permutation (CP) relationships. First, we propose an efficient algorithm for rapid identification of both exact and approximate CPs in multidomain proteins. Using the circular relations identified, we construct networks between multidomain proteins, based on which we perform …

Error-Related Negativities During Spelling Judgments Expose Orthographic Knowledge, Lindsay N. Harris, Charles A. Perfetti, Benjamin Rickles Jan 2014

Error-Related Negativities During Spelling Judgments Expose Orthographic Knowledge, Lindsay N. Harris, Charles A. Perfetti, Benjamin Rickles

Faculty Articles, Papers, and Other Scholarship

In two experiments, we demonstrate that error-related negativities (ERNs) recorded during spelling decisions can expose individual differences in lexical knowledge. The first experiment found that the ERN was elicited during spelling decisions and that its magnitude was correlated with independent measures of subjects’ spelling knowledge. In the second experiment, we manipulated the phonology of misspelled stimuli and observed that ERN magnitudes were larger when misspelled words altered the phonology of their correctly spelled counterparts than when they preserved it. Thus, when an error is made in a decision about spelling, the brain processes indexed by the ERN reflect both phonological …

Public Injunctions As A Way Around Concepcion: California's Continued Resistance To The Federal Arbitration Act, Elizabeth Kiesewetter Jan 2014

Public Injunctions As A Way Around Concepcion: California's Continued Resistance To The Federal Arbitration Act, Elizabeth Kiesewetter

Journal of Dispute Resolution

This note outlines the general applicability of the FAA and preemption. Next, it examines the Supreme Court's precedent concerning preemption, as it relates to class actions and public policy. This note argues that California's public injunction exception does prohibit outright the arbitration of a particular type of claim and is, thus, preempted by the FAA. The Supreme Court will likely see this rule as being at odds with the FAA and as another repudiation from the California courts of their long-standing FAA jurisprudence. Finally, this note argues that, despite the likely preemption of California's rule, there are strong policy arguments …

Pressure To Plead: How Case-Management Mediation Will Alter Criminal Plea-Bargaining, Taylor C. Leonard Jan 2014

Pressure To Plead: How Case-Management Mediation Will Alter Criminal Plea-Bargaining, Taylor C. Leonard

Journal of Dispute Resolution

This note first discusses the facts and proceedings in Milligan. Next, it explores the history and importance of plea-bargaining in the United States and how mediation has slowly become a part of criminal proceedings. Next, this note examines the Milligan court's reasoning for upholding the mediation plea bargain at issue in that case, in light of the legal landscape concerning ADR and the criminal justice system. Finally, this note argues in favor of using case-management mediation in criminal plea negotiations, and explores the proper methods and procedures to make these mediations successful.

Memory Self-Efficacy And Beliefs About Memory Controllability In Late Life, Bethany A. Lyon Jan 2014

Memory Self-Efficacy And Beliefs About Memory Controllability In Late Life, Bethany A. Lyon

LSU Master's Theses

The Selective Optimization with Compensation (SOC) model for lifespan development (Baltes & Baltes, 1990) holds that as we age, our goals change from growth to maintenance. When people face difficulties, they work to minimize losses in order to maintain skills they already have physically, mentally, and socially. Thus, we compensate when possible in order to maintain the life we have established. In the case of memory people assume that there is little they can do when memory starts to fail and forgetfulness becomes more prominent. In the present research, we examine memory self-appraisals to provide new evidence on memory self-efficacy …

Detection And Confirmation Of Veterinary Drug Residues In Commercially Available Frozen Shrimp, Jessica Danielle Johnson Jan 2014

Detection And Confirmation Of Veterinary Drug Residues In Commercially Available Frozen Shrimp, Jessica Danielle Johnson

LSU Master's Theses

Aquaculture has grown rapidly as the world’s wild-caught fisheries approach their sustainable limits. Feed conversion in aquaculture is more efficient than in terrestrial animals. Thus with a growing world population, seafood produced through aquaculture can provide a high quality source of protein. Aquaculture systems rely on high stocking densities and commercial feeds to increase production and profitability, which increase animal stress and susceptibility to disease. Veterinary drugs are commonly used to prevent and treat disease outbreaks. Several of these drugs are banned for use in shrimp farming in the United States. These drugs can be toxic to humans, with side …

Effect Of The Bp Deepwater Horizon Oil Spill On Critical Marsh Soil Microbial Functions, Jason Paul Pietroski Jan 2014

Effect Of The Bp Deepwater Horizon Oil Spill On Critical Marsh Soil Microbial Functions, Jason Paul Pietroski

LSU Master's Theses

On April 20, 2010, the BP Deepwater Horizon (DWH) offshore oil platform exploded releasing ~ 795 million L of southern Louisiana (LA) light sweet crude oil into the Gulf of Mexico. Approximately 7.9 million liters of dispersant, Corexit EC9500A, were applied for remediation. The effect of BP DWH crude oil and Corexit EC9500A on two marsh soil microbial processes, (mineralizable nitrogen and denitrification), were examined in the laboratory. Surface soil samples were collected from an unimpacted salt marsh site proximal to areas that suffered light to heavily oiling in Barataria Bay, LA. Additions of oil were at a ratio of …

Physico-Chemical Properties Of Green Leaf Volatiles, Harsha Satyanarayana Vempati Jan 2014

Physico-Chemical Properties Of Green Leaf Volatiles, Harsha Satyanarayana Vempati

LSU Master's Theses

Green Leaf Volatiles (GLVs) is a class of vegetation emissions whose release is greatly enhanced in the event of thermal or mechanical stress. These oxygenated hydrocarbons that have been identified as a potential source of Secondary Organic Aerosols (SOA) via aqueous oxidation. The physico-chemical properties of GLVs are vital to understanding their fate and transport in the atmosphere, but few experimental data are available. We studied the aqueous solubility, 1-Octanol/Water Partition Coefficient, and Henry’s Constant (KH) of five GLVs at 25&176;C: methyl jasmonate, methyl salicylate, 2-methyl-3-buten-2-ol, cis-3-hexen-1-ol, and cis-3-hexenyl acetate. Henry’s constant was additionally measured at 30&176;C & 35&176;C, and …

Essays On Mortgage Securitizations, Hong Lee Jan 2014

Essays On Mortgage Securitizations, Hong Lee

LSU Doctoral Dissertations

This dissertation studies how the affiliation between different entities in securitization process make different market outcomes, and how this estimation of affiliation effects is susceptible to limitations in securitized residential mortgage data. Three essays constitute the dissertation. The first essay illustrates the limitations and potential bias in the loan-level trustee data. Substantial amounts of loan attributes and risk factors are missing. The patterns of data omissions dramatically vary across different risk factors, sponsors, and trustees, and over the time. Missing of one risk factor is in general positively correlated with missing of the other. Omissions of loan attributes are systematically …

The Pulpit And The Nation: Clergymen, Political Culture, And The Creation Of An American National Identity, Spencer W. Mcbride Jan 2014

The Pulpit And The Nation: Clergymen, Political Culture, And The Creation Of An American National Identity, Spencer W. Mcbride

LSU Doctoral Dissertations

This dissertation examines the politicization of clergymen during the American Revolution and explains the direct impact this process had on the development of a national polity and a distinct American national identity in the early republic. Both during and after the Revolution, clergymen utilized providential rhetoric and biblical symbolism to assign greater religious and moral significance to political events. Focusing on the period between 1775 and 1800, this dissertation describes and analyzes the extent to which national political leaders relied on local clergymen when securing independence and thereafter inventing a new nation. Ultimately, it argues that clergymen were essential to …

Some Numerical And Phenomenological Studies In Loop Quantum Cosmology, Brajesh Kumar Gupt Jan 2014

Some Numerical And Phenomenological Studies In Loop Quantum Cosmology, Brajesh Kumar Gupt

LSU Doctoral Dissertations

A key feature of the singularity resolution in loop quantum cosmology (LQC) is the occurrence of the quantum bounce when the spacetime curvature becomes comparable to the Planck scale. The presence of quantum bounce greatly modifies the dynamics of the early universe and can have important implications for observational signatures. Although the quantum bounce has been previously studied via numerical methods for initial conditions that correspond to large macroscopic universes at late times, a detailed study of the robustness of the quantum bounce for a generic class of initial condition has so far been missing due to severe computational challenges. …

Energy Dissipation And Entropy Generation During The Fatigue Degradation: Application To Health Monitoring Of Composites, Ali Kahirdeh Jan 2014

Energy Dissipation And Entropy Generation During The Fatigue Degradation: Application To Health Monitoring Of Composites, Ali Kahirdeh

LSU Doctoral Dissertations

In this dissertation, an experimental approach for characterizing energy dissipation and degradation evolution in a woven Epoxy/Glass (G10/FR4) laminate subjected to fully reversed bending fatigue test is presented. Infrared thermography and acoustic emission are utilized to characterize the degradation progression. The results show similar evolutionary response indicating the presence of three degradation stages. The effect of the surface cooling on the fatigue life of the laminates is investigated both experimentally and analytically. The results show that the life of the laminate is highly dependent on the temperature and that surface cooling can significantly increase the fatigue life of the laminate. …

Chronic Toxicity Of Nano Metallics On Red Swamp Crayfish (Procambarus Clarkii) In Laboratory And Mesocosm Studies, Jake Andrew Farlow Jan 2014

Chronic Toxicity Of Nano Metallics On Red Swamp Crayfish (Procambarus Clarkii) In Laboratory And Mesocosm Studies, Jake Andrew Farlow

LSU Master's Theses

Nanotechnology has become integrated in commercial, industrial and medical products, and its use has grown exponentially in the past several years. Although potential applications of nanoparticles (NPs) are numerous, concerns about their water quality, environmental, and human health impacts remain unclear. Crayfish are ubiquitous to streams and wetland habitats, are used as a food source, and inhabit areas that could be impacted by water quality issues. Numerous studies have been conducted on the toxicity of various classes of agricultural pesticides and oils to crayfish (Procambarus clarkii) as a non-target organism. However, there is little evidence published on chronic toxicity of …

Factor Analysis And Cut-Off Scores For The Autism Spectrum Disorders-Observation For Children, Megan Alice Hattier Jan 2014

Factor Analysis And Cut-Off Scores For The Autism Spectrum Disorders-Observation For Children, Megan Alice Hattier

LSU Doctoral Dissertations

Optimal prognoses for children with Autism Spectrum Disorders (ASDs) often rely upon early intervention; thus, there has been a call for reliable and valid assessment tools in order to ensure accurate diagnoses among youth at risk for developmental disabilities (DDs) such as autism. The target of this paper is to inspect the underlying factor structure of a recently developed observation tool for assessing autistic symptoms, the Autism Spectrum Disorders – Observation for Children (ASD-OC). More importantly, cutoff scores were also developed for clinical use in order to distinguish between those with and without an ASD. Given that marked changed were …

Teaching Climate Literacy Using Geospatial Tools, Steven L. Babcock Jan 2014

Teaching Climate Literacy Using Geospatial Tools, Steven L. Babcock

LSU Master's Theses

Antarctica is the world’s coldest, driest and windiest continent. It is a harsh environment that few people will ever see but it is a very important part of our Earth system. Over the past 34 million years the climate in Antarctica has deteriorated from one that supported lush vegetation to the conditions observed today. By studying this trend and the associated changes to ice and vegetation we can gain critical insight into climate changes taking place today. This thesis presents three pieces of curricula that will help students and the general public understand some of the research currently underway in …

The (In)Visible Road Map: The Role Of Mentoring For First-Generation Black Female Doctoral Students At Predominantly White Institutions, Takea Vickers Jan 2014

The (In)Visible Road Map: The Role Of Mentoring For First-Generation Black Female Doctoral Students At Predominantly White Institutions, Takea Vickers

LSU Doctoral Dissertations

Although women’s status in higher education has vastly improved over the past decades, invisible barriers remain that disenfranchise first-generation Black female doctoral students at predominantly White institutions (PWI). Specifically, the sparse literature base constricts existing knowledge and understanding about the mentoring relationships of first-generation Black female doctoral students and the barriers they face in the academy. Using the theoretical framework of intersectionality, this study sought to address the ways in which first-generation Black female doctoral students navigated the academy through mentorship and the ways in which mentoring relationships were formidable to construct. Five first-generational Black female doctoral students and two …

Examining The Boundary Conditions Between Cognitive Control And Interference Derived From Stimulus-Based And Response-Based Conflict, Jonathan D. Tall Jan 2014

Examining The Boundary Conditions Between Cognitive Control And Interference Derived From Stimulus-Based And Response-Based Conflict, Jonathan D. Tall

LSU Doctoral Dissertations

Cognitive control is a broad construct that defines a set of processes involved in maintaining task goals in response to interference. Working memory capacity (WMC) is a similarly defined construct that shares many overlapping functions with cognitive control. The studies presented used controlled forms of interference to identify limits, or boundary conditions, that could help clarify the relationship between cognitive control and WMC. Experiment 1 used context effects to manipulate how interference and cognitive control could overlap. A spatial Stroop/Simon task was used in which proportion congruency for each subset (e.g., Simon or spatial Stroop) was manipulated to produce a …

Spectrum Sensing, Spectrum Monitoring, And Security In Cognitive Radios, Erfan Soltanmohammadi Jan 2014

Spectrum Sensing, Spectrum Monitoring, And Security In Cognitive Radios, Erfan Soltanmohammadi

LSU Doctoral Dissertations

Spectrum sensing is a key function of cognitive radios and is used to determine whether a primary user is present in the channel or not. In this dissertation, we formulate and solve the generalized likelihood ratio test (GLRT) for spectrum sensing when both primary user transmitter and the secondary user receiver are equipped with multiple antennas. We do not assume any prior information about the channel statistics or the primary user’s signal structure. Two cases are considered when the secondary user is aware of the energy of the noise and when it is not. The final test statistics derived from …

Changes In Climate And Moisture Availability In The Antarctic Eocene, Oligocene, And Miocene: Evidence From Palynological And Stable Isotope Geochemical Analyses Of The Shaldril And Andrill Cores, Kathryn Whitney Griener Jan 2014

Changes In Climate And Moisture Availability In The Antarctic Eocene, Oligocene, And Miocene: Evidence From Palynological And Stable Isotope Geochemical Analyses Of The Shaldril And Andrill Cores, Kathryn Whitney Griener

LSU Doctoral Dissertations

Prior to the Late Eocene, the Antarctic continent experienced lush vegetation under temperate conditions. Just before the Eocene/Oligocene Boundary, the climate of the southernmost continent began to deteriorate dramatically. This cooling trend largely continued until most Antarctic vegetation disappeared, ~13.85-12.8 Ma. Classifying the nature and cause of Antarctica’s drastic climate change is essential for furthering our knowledge of Earth’s history, and also for grasping the potential effects of current and future climate shifts. Here, I present evidence from three new palynomorph-centric studies that deepen our understanding of Antarctic earth science, climate change, and of climate proxies. The first study involved …

Evaluating Alternative Techniques For Forecasting Industrial And Occupational Employment, Drew A. Varnado Jan 2014

Evaluating Alternative Techniques For Forecasting Industrial And Occupational Employment, Drew A. Varnado

LSU Doctoral Dissertations

This paper offers three different regional output-by-industry forecasting techniques (time series, Social Accounting Matrix (SAM)-based, and Computable General Equilibrium (CGE)-based) and two different occupation-by-industry matrices (national and state geographies) for use in the creation of industry/occupation employment forecasts. Estimates are compared to actual data from eight years from 2001 to 2010. OLS regressions are run to determine how well modeled employment estimates fit actual employment for the state of Louisiana. A meta-analysis style regression of the R-sqaured values on model characteristics (accounted for using Boolean dummy-variables) determines that industrial output forecasting techniques do not provide statistically different R-squared values, but …

Evaluation Of Stromatolites From The 3.4 Ga Kromberg Formation, Barberton Greenstone Belt, South Africa, Corey E. Shircliff Jan 2014

Evaluation Of Stromatolites From The 3.4 Ga Kromberg Formation, Barberton Greenstone Belt, South Africa, Corey E. Shircliff

LSU Master's Theses

Silicified sedimentary rocks from the 3.4 Ga Kromberg Formation of the Barberton Greenstone Belt in South Africa contain laminated structures that have been identified as possible stromatolites in the field. Morphological evaluation and a variety of chemical analyses are presented here, in an effort to describe the samples in a sedimentary context and consider biogenicity of these laminated forms. Two major types of laminated structures were identified in the field – domical laminates and flat-laminated samples with little to no synoptic relief. The domical sample presents the best morphological evidence for biogenicity. There are several characteristics that suggest the deposition …

Robust Preconditioners For The High-Contrast Elliptic Partial Differential Equations, Zuhal Unlu Jan 2014

Robust Preconditioners For The High-Contrast Elliptic Partial Differential Equations, Zuhal Unlu

LSU Doctoral Dissertations

In this thesis, we discuss a robust preconditioner (the AGKS preconditioner) for solving linear systems arising from approximations of partial differential equations (PDEs) with high-contrast coefficients. The problems considered here include the standard second and higher order elliptic PDEs such as high-contrast diffusion equation, Stokes' equation and biharmonic-plate equation. The goal of this study is the development of robust and parallelizable preconditioners that can easily be integrated to treat large configurations. The construction of the preconditioner consists of two phases. The first one is an algebraic phase which partitions the degrees of freedom into high and low permeability regions which …
