A Novel Automated Approach Of Multi-Modality Retinal Image Registration And Fusion, Hua Cao

LSU Doctoral Dissertations

Biomedical image registration and fusion are usually scene dependent, and require intensive computational effort. A novel automated approach of feature-based control point detection and area-based registration and fusion of retinal images has been successfully designed and developed. The new algorithm, which is reliable and time-efficient, has an automatic adaptation from frame to frame with few tunable threshold parameters. The reference and the to-be-registered images are from two different modalities, i.e. angiogram grayscale images and fundus color images. The relative study of retinal images enhances the information on the fundus image by superimposing information contained in the angiogram image. Through the …

Performing Photographs: Memory, History, And Display, Melanie A. Kitchens

LSU Doctoral Dissertations

In my study, I place concepts and practices of photography and performance in dialogue to enable our understanding of how photographs perform and how performance contains or can contain elements we attribute to photographs. The connection between photography and performance that most intrigues me is how they make memories and when collected or restored in some socially shared way make histories too. My specific aim is to understand how photographs and performance might benefit from each other in how they make and transmit memories and histories. To activate the study, I select and focus on five specific events in which …

Application Of The Hyman Model To Evaluate The Water And Salt Budgets In Three Mangrove Sites Along Shark River, Everglades, Cheng-Feng Tsai

LSU Master's Theses

Mangrove trees play an important role in the maintenance and sustainability of coastal wetlands due to their ability to adapt and survive in a wide range of saline and tidal conditions. Hydrologic processes (e.g., inundation frequency) and salinity are important regulators controlling the growth and productivity of mangrove forests. To quantify how changes in landscape-level hydrology will influence these regulators in mangrove forests, the hydrology model (HYMAN) was applied to three sites with distinct tidal forcings along the Shark River estuary in the Everglades National Park. HYMAN model uses mass balance equation to determine daily water and salt budgets as …

The Relationship Between Early Cumulative Caregiver Sensitivity And Children's Later Self-Perception Of Cognitive Competence And Cognitive Performance, Jenna Rae Watson

LSU Master's Theses

The purpose of the study was to examine the relationship between children’s experiences of caregiver sensitivity during the first three years of their life and their later self-perceptions of cognitive competence and cognitive performance. Caregiver sensitivity was measured using data that had been collected with the Caregiver Interaction Scale (CIS, Arnett, 1989) during an earlier longitudinal study, the Baton Rouge Early Care Study (BRECES; Pierce & Benedict, 2007). Measures of cognitive competence were derived using the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children (Harter & Pike, 1984) and measures of cognitive performance were derived using the …

Wax Extraction And Characterization From Full-Fat And Defatted Rice Bran, Junghong Kim

LSU Doctoral Dissertations

Rice bran oil (RBO) contains 3-4% waxes (rice bran wax, RBW), which are composed of wax esters (WE), hydrocarbons, and other minor constituents. Saponified rice bran wax esters (RBWE) generate fatty acids, long chain alcohols, and phytosterols. Phytosterols and long chain fatty alcohols (policosanol) are known to reduce serum cholesterol and inhibit hepatic cholesterol synthesis. The yields and RBWE contents of RBO and RBW extracted from full-fat RB (FFRB) and defatted RB (DFRB) were determined using 6 different conditions with Soxhlet and Microwave-assisted extraction (MAE). The compositions of WEs from RBO and RBW were also compared. RBW was obtained from …

Evaluation Of Three Methods For Teaching Intraverbals To Children With Language Delays, Nicole Trosclair-Lasserre

LSU Doctoral Dissertations

Direct instruction is often necessary to develop language or expand language use in individuals with language delays. Previous research has begun to identify certain training conditions that result in more efficient use of instructional time devoted to language development. Specifically, incorporating mands into the instructional arrangement, increasing the quality of reinforcement delivered for interspersed tasks, and including instructive feedback stimuli into the consequences of learning trials have all demonstrated more efficient learning of targeted language skills. The purpose of the current investigation was to compare three methods for teaching intraverbals (i.e., conversation skills) to individuals with deficits in this area. …

The Mise En Scène Of Rossini's Le Siège De Corinthe And The Conventions Of Staging At The Paris Opéra In The 1820s, Tina Huettenrauch

LSU Master's Theses

Shortly before 1800, the publication of livrets de mise en scène, short manuals including information regarding costumes, set designs, and blocking (i.e., the movement of characters on stage), became increasingly popular in France. While theater scholars (Gösta M. Bergman, Marvin Carlson, Hellmuth Christian Wolff) have recognized the value of these documents for the history of staging (and blocking in particular), musicologists have tended to focus on their impact on visual aspects and realization of drama. Those who have looked at staging (H. Robert Cohen, Rebecca S. Wilberg, M. Elizabeth C. Bartlet) have largely ignored the period prior to 1827, …

Pet/Ct Detectability And Classification Of Simulated Pulmonary Nodules Using An Suv Correction Scheme, Andrew Nicholas Morrow

LSU Master's Theses

Positron emission tomography (PET) and computed tomography (CT) together are a powerful diagnostic tool, but imperfect image quality contributes to false positive and false negative diagnoses by an observer despite experience and training. This work investigated a PET standard uptake value (SUV) correction scheme, based on partial volume effect (PVE), on the classification of lesions as benign or malignant in PET/CT images. The correction scheme comprised several steps. The observer drew a region of interest (ROI) around the lesion using the CT dataset. The ROI was blurred with the assumed point spread function (PSF) of the PET scanner then re-sampled …

Mercury Transport Through A Capped Sediment, Jianrong Liu

LSU Doctoral Dissertations

Laboratory simulation cells were employed to evaluate the effectiveness of a sand cap for containing highly mercury-contaminated lake sediments and the resultant impacts on the mercury fate beneath the cap. Sand cap can delay and reduce the migration of mercury into the overlying water; however, due to the small partition coefficient of mercury between sand and water, a capping material with higher partition coefficient is better for the long-term containment of mercury. In the following study, efforts were made to identify and investigate an active capping material which works effectively at containing and inhibiting the methylation of mercury. Based on …

Teachers' Perspectives On The Unintended Consequences Of High Stakes Testing, David Christopher Charles

LSU Doctoral Dissertations

A mixed methods design was utilized that was divided into three phases to verify and explore high stakes testing’s effects on teachers’ perceptions regarding classroom practices, pressure, and commitment to the educational profession. Phase I utilized previous surveys and a peer review to create a knowledge base to generate a survey instrument that measured the three areas assumed to be affected by high stakes testing (commitment, pressure, and classroom practice). The survey instrument that was created was piloted. Throughout Phase II there was a series of three-step analysis: First, the means and standard deviations from the results of the surveys …

Message Framing And Interactivity In Direct-To-Consumer Internet Advertisements: Visual And Textual Cues On Web Sites For Prescription Medications, Brooke Alayne Harrington

LSU Master's Theses

Americans’ adoption of the Internet has spawned the increased usage of this medium for direct-to-consumer advertising by pharmaceutical manufacturers, despite the widespread controversy over the ethics of the practice, the educational value of direct-to-consumer advertising, and the ultimate cost of the practices to the public. While the U.S. Food and Drug Administration regulates the industry’s advertising within traditional media, the agency does not yet impose standards for direct-to-consumer advertising of prescription medications on the Internet. This content analysis of the visual and textual cues of 100 direct-to-consumer Web sites for prescription medications identifies the unexpected strong presence of gain frames …

Factors Affecting Young Driver Safety In The State Of Louisiana, Cherian Cherian-Korah

LSU Master's Theses

Though teenage drivers constitute only 6.4 percent of the total drivers in United States, they are responsible for 14 percent of the fatal crashes and are involved in 18 percent of all police-reported crashes in the country. One of the main causes of teenage crashes was found to be the presence of passengers in the vehicle. This study is focused on the effect of passengers on young drivers in the state of Louisiana. There have been efforts from traffic safety departments to contain crashes involving this age group of drivers and, particularly the Graduated Driver's License Law, which imposes restrictions …

Tax Fairness And The Tax Mix, David G. Duff

All Faculty Publications

Since a society’s tax system is one of its most basic and essential social institutions, the justice or fairness of this tax system is an important subject for social and political theory, as well as for practical politics. In order to assess the fairness of any particular tax or the tax system as a whole, however, it is essential to consider the purpose of the tax and the tax system in general. While the most obvious purpose of most taxes is to raise revenue to finance public expenditures, taxes are also employed to regulate social and economic behaviour and to …

Limit On The Muon Neutrino Magnetic Moment And A Measurement Of The Ccpip To Ccqe Cross Section Ratio, Serge Arisitde Ouedraogo

LSU Doctoral Dissertations

A search for the muon neutrino magnetic moment was conducted using the Mini- BooNE low energy neutrino data. The analysis was performed by analyzing the elastic scattering interactions of muon neutrinos on electrons. The analysis looked for an excess of elastic scattering events above the Standard Model prediction from which a limit on the neutrino magnetic could be set. In this thesis, we report an excess of 15.3}6.6(stat)}4.1(syst) elastic scattering events above the expected background. At 90% C.L., we derived a limit on the muon neutrino magnetic moment of 12.7~ 10−10ƒÊB. The other analysis reported in this thesis is a …

Heterogeneous Catalyzed Macromolecular Hydrogenations In Oscillating Systems, Alan Bussard

LSU Doctoral Dissertations

An examination of novel oscillatory (alternating gas and liquid phase) reactors and heterogeneous catalysts for multi-phase macromolecular reactions was carried out. A monolith-containing square die with Pd/Al2O3 catalysts was used to successfully hydrogenate poly(styrene) (PS). The inherent pulse behavior of the extruder was found to be sufficient to approach intrinsic kinetics at low polymer concentrations. At higher (10 wt% PS) concentrations, forced pulsing was shown to have a greater impact on observed reaction rates. Selectivity with this extruder-fed reactor was better than with a stirred tank in all cases, due to a more plug-flow-like residence time distribution. While accurate control …

Quantifying Twentieth Century Glacier Change In The Sierra Nevada, California, Hassan J. Basagic

Dissertations and Theses

Numerous small alpine glaciers occupy the high elevation regions of the central and southern Siena Nevada, California. These glaciers change size in response to variations in climate and are therefore important indicators of climate change. An inventory based on USGS topographic maps (l :24,000) revealed 1719 glaciers and perennial snow and ice features for a total area of 39.l5 ±7.52 km². The number of 'true' glaciers, versus non-moving ice, is estimated to be 118, covering 15.87 ± 1.69 Km². All glaciers were located on north to northeast aspects, at elevations >3000 m. Historical photographs, geologic evidence, …

Measuring And Achieving Quality Customer Service: A Study On Public Sector In Malaysia, Muhammad Hafiz Rashid

Theses

Excellent quality of customer service is so important for government agencies even though they are not-for-profit. Better service enhances productivity, and treating customer right the first time saves time and money. Creating satisfied customers reduces the likelihood irate citizens take their complaints to higher sources, or to a public forum where negative word-of-mouth can be damaging. A common criticism of the public in Malaysia has been the poor quality of customer service rendered by employees in government agencies. As the largest organization in Malaysia, the quality of service they provide has a tremendous influence on public perceptions of the quality …

In The Trenches: Searches And The Misunderstood Common-Law History Of Suspicion And Probable Cause, Fabio Arcila

Scholarly Works

A detailed analysis of the common law during the Framers’ era, and of how it reflected the Fourth Amendment’s restrictions, shows that many judges believed they could issue search warrants without independently assessing the adequacy of probable cause, and that this view persisted even after the Fourth Amendment became effective. This conclusion challenges the leading originalist account of the Fourth Amendment, which Professor Thomas Davies published in the Michigan Law Review in 1999.

Learned treatises in particular, and to a lesser extent a few case decisions, had articulated a judicial duty to monitor probable cause. But it is a mistake …

A Response To Professor Steinberg’S Fourth Amendment Chutzpah, Fabio Arcila

Scholarly Works

Professor David Steinberg believes that the Fourth Amendment was intended only to provide some protection against physical searches of homes through imposition of a specific warrant requirement because the Framers' only object in promulgating the Fourth Amendment was to ban physical searches of homes under general warrants or no warrants at all. This response essay takes issue with his thesis by (1) discussing its implications, (2) reviewing some concerns with his methodology in reviewing the historical record, and (3) examining the theoretical implication underlying his thesis that, except as to homes, we have a majoritarian Fourth Amendment, and questioning whether …

Stressor- And Corticotropin Releasing Factor-Induced Reinstatement And Active Stress-Related Behavioral Responses Are Augmented Following Long-Access Cocaine Self-Administration By Rats, John R. Mantsch, David A. Baker, David M. Francis, Eric S. Katz, Michael A. Hoks, Joseph P. Serge

Biomedical Sciences Faculty Research and Publications

Rationale Stressful events during periods of drug abstinence likely contribute to relapse in cocaine-dependent individuals. Excessive cocaine use may increase susceptibility to stressor-induced relapse through alterations in brain corticotropin-releasing factor (CRF) responsiveness.

Objectives This study examined stressor- and CRF-induced cocaine seeking and other stress-related behaviors in rats with different histories of cocaine self-administration (SA).

Materials and methods Rats self-administered cocaine under short-access (ShA; 2 h daily) or long-access (LgA; 6 h daily) conditions for 14 days or were provided access to saline and were tested for reinstatement by a stressor (electric footshock), cocaine or an icv injection of CRF and …
