Giftedness And Overexcitability : Investigating The Evidence, Daniel Lawrence Winkler
Giftedness And Overexcitability : Investigating The Evidence, Daniel Lawrence Winkler
LSU Doctoral Dissertations
Many scholars of gifted education have often argued and believed that gifted individuals are neurologically overexcitable while non-gifted persons are not (Chang & Kuo, 2013; Harrison & Haneghan, 2011; Piechowski, 1979, 2006; Silverman, 2000a; Siu, 2010; Tieso, 2007a). This means that gifted persons are more sensitive, intuitive, empathic, and physically and emotionally aware. Some scholars have suggested that this significant degree of overexcitability may even mean that gifted persons are morally superior to non-gifted persons (Silverman, 1994). Over the past thirty years, this relationship between overexcitability (OE) and giftedness has become increasingly popular, as many websites, textbooks, and researchers have …

More specifically, we are interested in restoration of statistics of individual occupancy patterns of specific users based on wireless RF observation traces. In particular, we present a novel approach to finding the statistics of several operations, namely down-sampling, …
Differential Examination Of Disgust In Spider, Blood-Injection, And Contamination Fear: Self-Reported And Attention-Based Assessment Of Differences, Whitney Shay Jenkins
Differential Examination Of Disgust In Spider, Blood-Injection, And Contamination Fear: Self-Reported And Attention-Based Assessment Of Differences, Whitney Shay Jenkins
LSU Doctoral Dissertations
Biased attention toward threat has been demonstrated across anxiety disorders as well as among nonclinical samples. While such studies have produced findings of attentional bias for fear-related or threatening stimuli, other types of emotionally laden stimuli have been ignored. This study sought to examine the experience and impact of disgust on individuals experiencing various types of anxiety, which may play a more significant role than fear in some disorders such as obsessive-compulsive disorder (OCD) and some specific phobias. Specifically, this study examined self-reported disgust and attentional bias in relation to disgust and threatening stimuli. A modified dot-probe task with pictorial …

Polycyclic Aromatic Hydrocarbon Degradation In Tidally Influenced Coastal Marsh Wetland Studied In Laboratory Mesocosm, Doorce S. Batubara
Polycyclic Aromatic Hydrocarbon Degradation In Tidally Influenced Coastal Marsh Wetland Studied In Laboratory Mesocosm, Doorce S. Batubara
LSU Doctoral Dissertations
The compact mesocosm which was designed for a laboratory scale was used for the kinetic study of refractory organic compounds in a tidally influenced coastal marsh wetland soil. The tidal cycles were controlled pneumatically using an air chamber inside the mesocosm tank. Phenanthrene as the test compound showed that its degradation in the intertidal wetland soil was faster than that in the subtidal wetland soil. Oxygen resupply during the tidal cycles to the intertidal wetland soil would enhance the degradation. Comparison of degradation rates of phenanthrene (Phe), pyrene (Pyr), and benzo[e]pyrene (BeP) were also studied using the mesocosm. The degradation …

Evaluation Of Triploid Oysters As A Tool To Assess Short- And Long-Term Seafood Contamination Of Oil Spill-Impacted Areas, Martin Scott Miles
Evaluation Of Triploid Oysters As A Tool To Assess Short- And Long-Term Seafood Contamination Of Oil Spill-Impacted Areas, Martin Scott Miles
LSU Doctoral Dissertations
Many of the organic components of oil have the capacity to persist in the environment, bioaccumulate in tissues, and are toxic to surrounding organisms. Since the early 1970s, environmental assessment programs have utilized bivalves as monitoring tools of chemical contaminants in the marine environment. Because of their sedentary and filter-feeding habit (bioaccumulation), mussels and oysters been employed as sentinel organisms in environmental quality monitoring studies in coastal ecosystems. The use of indigenous (diploid) bivalves for biomonitoring water quality is limited during the summer months due to high stress and changes in biochemical composition induced by reproductive development. In this work …

LSU Doctoral Dissertations
Social media is being used as platforms for viral marketing. Although there is some evidence on the usefulness of viral marketing from the marketers’ perspective, little is known about the motivations, attitudes, and behaviors of consumers engaged in this marketing instrument. As the social media platform continues to grow, understanding the characteristics and motivations of key players is invaluable for marketers and communicators who deal with message strategy and media outreach. Fashion companies have noticed this change and want to be present in the social media in different ways. This research represents a comprehensive attempt to examine the factors that …
Queer Emplotment: Lesbian Caretaking In North American Canonical Fiction From 1980 – 2011., Penelope Gay Dane
Queer Emplotment: Lesbian Caretaking In North American Canonical Fiction From 1980 – 2011., Penelope Gay Dane
LSU Doctoral Dissertations
My dissertation argues that lesbian caretaking in late 20th century and early 21th century North American fiction disrupts normative temporalities while repairing damage protagonists sustain from intra-familial trauma. Aligned with queer studies’ growing interest in representations of time, my project explores this paradox of lesbian representation. How can lesbian characters be both reparative and disruptive? Lesbian characters in Alice Walker’s The Color Purple (1980); Dorothy Allison’s Bastard Out of Carolina (1992); and Louise Erdrich’s Shadow Tag (2010) are reparative as they clean up the psychological and physical damage caused male violence, sexual abuse, and neglectful mothers. Yet their caregiving disrupts …
Chemistry And Application Of Pulses As Value-Added Ingredients In Processed Foods, Darryl Holliday
Chemistry And Application Of Pulses As Value-Added Ingredients In Processed Foods, Darryl Holliday
LSU Doctoral Dissertations
Chemical characterization of pulses allows for varying rates of water absorption, least gelation capacity, and retrogradation depending on species. Nutritionally, pulses are good sources of protein while being low in fat. Pulses deliver a readily bioavailable food form of several key minerals. Additionally, they deliver fiber. The insoluble fiber components are both natural and formed resistant starch in addition to the oligosaccharide content. Therefore, pulses can serve both a nutritional and functional role when used as a value-added ingredient. Meat patties were produced from beef and 23 different pulses at 35%, 42.5%, and 50% ratios. Each patty was tested for …
Holocene Paleoenvironmental Reconstruction From Mexico's Pacific Coast-A Paleotempestological Investigation, Thomas Bianchette
Holocene Paleoenvironmental Reconstruction From Mexico's Pacific Coast-A Paleotempestological Investigation, Thomas Bianchette
LSU Doctoral Dissertations
This dissertation examines the paleoenvironments of four lagoons from Mexico’s Pacific coast, with the aim of retrieving sediment deposition from storm surge events to determine long-term tropical cyclone (TC) records. Lagoons Agua Dulce, Boquita, Mitla, and Nuxco are located along a 700 km stretch in states Jalisco and Guerrero. Roughly 70 meters of sediment were collected and subjected to multiple proxies, including loss-on ignition, a microfossil survey, and geochemical analysis. Nuxco’s dynamism is caused by intense and prolonged rainfall (largely from TCs), responsible for increasing water level, opening the tidal inlet, and draining the site (termed “blowouts”). High amounts of …
Biogeographical Approaches For Studying Species Invasion, Ganesh Prasad Bhattarai
Biogeographical Approaches For Studying Species Invasion, Ganesh Prasad Bhattarai
LSU Doctoral Dissertations
Many of the most notorious biological invasions occur at continent-wide or global scales but studies investigating mechanisms enhancing species invasions are often conducted at small spatial scales. Moreover, the contribution of mechanisms facilitating invasion might also vary across a geographical space. I used biogeographical approaches to explore the mechanisms enhancing invasion of introduced genotypes of Phragmites australis along the coastal wetlands of North America. I tested the hypotheses that large-scale disturbance events, such as hurricanes and tropical storms, enhance the invasion success of introduced P. australis in North America. The growth rate of P. australis patches was strongly and positively …

LSU Doctoral Dissertations
The collection of digital data is growing at an exponential rate. Data originates from wide range of data sources such as text feeds, biological sequencers, internet traffic over routers, through sensors and many other sources. To mine intelligent information from these sources, users have to query the data. Indexing techniques aim to reduce the query time by preprocessing the data. Diversity of data sources in real world makes it imperative to develop application specific indexing solutions based on the data to be queried. Data can be structured i.e., relational tables or unstructured i.e., free text. Moreover, increasingly many applications need …
Thrillology: Affective Intensities And The Everyday-Spectacular In American Literature And Culture, Peter James Pappas
Thrillology: Affective Intensities And The Everyday-Spectacular In American Literature And Culture, Peter James Pappas
LSU Doctoral Dissertations
“Thrillology: Affective Intensities and the Everyday-Spectacular in American Literature and Culture” presents thrill as a powerful thematic component centered on immediate affective gratification informing character development and narrative. This perspective rethinks theme as always having an affective dimension that accompanies its conceptual articulations, with the former, in many cases, being the more important element. Thrilled psycho-emotional states emerge, in their own right, as legitimizations of individuality and cultural autonomy from the perspective of the passional subject. Engaging with a broad spectrum of literary and cultural sources spanning the last hundred years, this project investigates various ways in which the self-fulfilling …

Evaluating Teaching Efficiency In Reading And Spelling Instruction, Sarah Joanne Miller
LSU Doctoral Dissertations
Reading and spelling are essential skills for a student’s educational success. The current literature on spelling instruction has examined a variety of spelling modalities, but has never directly compared written versus oral spelling. There are theoretical and empirical indications that either method may be superior to the other. Thus, study one directly compared written and oral spelling instruction for their rates of spelling acquisition as well as generalization to reading. The results of study 1 indicated that written spelling was superior to oral spelling in rates of acquisition of both spelling and reading accuracy. Previous research has also indicated that …

Evidence Of Methane Cycling Beneath The Western Margin Of The Greenland Ice Sheet, Erik L. J. E. Broemsen
Evidence Of Methane Cycling Beneath The Western Margin Of The Greenland Ice Sheet, Erik L. J. E. Broemsen
LSU Master's Theses
The greenhouse gas methane mainly regulated by microbial processes. Methanogenic archaea, a major biological source of methane, are a diverse group of organisms that produce methane as a metabolic byproduct. The generation of methane takes place in diverse anoxic environments using CO2 and other reduced substrates. The release of methane into oxic environments often is regulated by methanotrophic Proteobacteria and Archaea, specialized groups of bacteria that use methane as sole sources of carbon and energy. These organisms can play major roles in the regulation of methane transport into the atmosphere and make up one part of the methane cycle. Pools …

History, Nesting Population, Migration, Home Range And Habitats Used By Louisiana Bald Eagles, Nickolas Ryan Smith
LSU Master's Theses
The population of Bald Eagles (Haliaeetus leucocephalus) nesting in Louisiana reached precariously low numbers in the early 1970’s, and although the population has since increased markedly, resident eagles remain a species of conservation concern in Louisiana. Using statewide aerial nest survey data from 1975–2008, I documented the history and quantified the recovery of the nesting population in Louisiana. Known active nests increased exponentially from 7 to 387 during this period, exhibiting a mean annual rate of increase of 11.1 ± 0.3% per year with no indications of slowing. By 1990, the nesting population in Louisiana had exceeded all goals of …

Effects Of Induced Plant Resistance And Potassium Fertilization Rates On Soybean Looper (Chrysodeixis Includens) Development In Soybean, Xuan Chen
LSU Master's Theses
Soybean looper, Chrysodeixis includens (Walker), is one of the most destructive pests of soybean in the southern U.S. It is highly resistant to most insecticides. Induced host plant resistance and cultural control are sought as alternative control tactics. In this study, effects of induced resistance by exogenous application of elicitors were estimated on soybean looper development in soybean. Three different known elicitors of SAR (systemic acquired resistance), Actigard 50WG (acibenzolar-S-methyl), Regalia (extract of Reynoutria sachalinensis) and methyl jasmonate (MeJA), were applied to soybean plants at R2 and R5 stages to determine if these chemicals could induce plant resistance and lower …
Electrical Resistivity Employed At The Livonia Mound Site (16pc1), Pointe Coupee Parish, Louisiana, Jennifer Patricia Gardner
Electrical Resistivity Employed At The Livonia Mound Site (16pc1), Pointe Coupee Parish, Louisiana, Jennifer Patricia Gardner
LSU Master's Theses
Electrical resistivity was used at the Livonia Mound site (16PC1) to identify construction breaks, possible human burials, and other cultural activity below the surface. Resistivity transects traveled across the mound and the level surface directly south of the mound; this latter section was called Area A. Four transects stretched across the north, south, west, and east slopes of the mound; as a result, four vertical profiles were created from the apparent resistivity (ƒâa) values. The standard deviation of each transect was computed using the ƒâa values from the four pseudo-sections to establish the base-line for analysis. ƒâa values for Area …
Paleoclimatology And Paleotempestology Study Of Blue Hole, Lighthouse Reef, Belize Through Geochemical Proxies, Laura Carolyn Sorey
Paleoclimatology And Paleotempestology Study Of Blue Hole, Lighthouse Reef, Belize Through Geochemical Proxies, Laura Carolyn Sorey
LSU Master's Theses
A large Pleistocene age sinkhole, the Blue Hole on Lighthouse Reef off the coast of Belize in the Caribbean Sea is the site of a well preserved sedimentary record that serves as paleoclimatology and paleotempestology archive. The nutrient-starved surface waters of the Blue Hole and the surrounding lagoons are “fertilized” by the seasonal introduction of cool, nutrient-rich waters upwelled from the Caribbean deep water. These waters, which stimulate production of organic materials within the surface waters, carry a heightened isotopic signature that is imparted to the organics resultant from upwelling-induced production. These organics are then incorporated into the predominantly carbonate …
