Palynological Analysis Of Tiger And Trinity Shoals, Louisiana Continental Shelf, Russell Ryan Crouch

LSU Master's Theses

Forty sediment samples taken from twenty-six vibracores collected from Holocene shoals (Tiger and Trinity) were processed for palynomorphs and analyzed to characterize the terrestrial and marine paleo-environments of southern Louisiana at the time of deposition of each shoal. Abundant and diverse pollen assemblages were recovered while marine microplankton were sparse (< 2% relative abundance). Pollen species were grouped by plants of similar environmental significances including arboreal, non-arboreal, aquatic, and shrub categories. Palynological signals were compared in detail between each core, as well as along strike and dip transects, to help determine whether or not these shoals were deposited coevally or in distinct depositional cycles. Evidence shows that Tiger and Trinity Shoals carry remarkably similar palynological profiles, indicating that sediments of these shoals areS from the same source, and that deposition extended over an interval of time such that climate change was not sufficient enough to alter the vegetation response (hence palynological signal). Pollen profiles show source sediments are predominantly from the lower Mississippi River drainage basin and exhibit species similar to those present in modern Louisiana coastal marshes and swamps (i.e., Taxodium distichum, Cyperaceae, Graminae, Chenopodiaceae, and Asteraceae), and coastal to upland hardwood forests of the Mississippi River alluvial valley (i.e., Pinus, Quercus, Carya, and Liquidambar styraciflua).

Designing Irishness: Ethnicity, Heritage, And Imagined Connection To Place Through Language, Thomas James Sullivan

LSU Doctoral Dissertations

In North America, those who are descended from "old world" immigrant groups—for example Germans, Greeks, Italians, Poles, and Irish—are thought to be assimilated or acculturated into the mainstream American culture. Since the late 1970s, however, sociologists have observed how a number of white ethnics, particularly those descended from third- and fourth-generation (and beyond) immigrants, continue to maintain a link to an ethnic group. This phenomenon—labeled symbolic or optional ethnicity—is now seen as a latter-stage development in the larger process of assimilation and ethnic-group identification. In this dissertation I show how the meaning of Irish identity has evolved in North America …

"Blessed Be The Critics Of Newspapers": Journalistic Criticism Of Journalism 1865-1930, Yasmine Tarek Dabbous

LSU Doctoral Dissertations

This study examined journalistic press criticism between 1865 and 1930. It sought to understand how the first modern journalists conceived of their profession in a period of great transitions. As the study revealed, journalists writing about journalism between 1865 and 1930 discussed recurring themes such as commercialization, sensationalism, advertising, and ethics. They expressed ambivalence toward the rise of big business in their field and the consequences it could have on the quality of the work. In the process, journalists also defined journalism as a profession providing a public service or as a business aiming solely for circulation and profit. Definitions …

Dry Event Trends And Frequencies In The South Central United States, Michael Roberts

LSU Master's Theses

In this study, dry spells in the southern United States are analyzed. Dry spells are defined as consecutive days with no recorded rainfall. Seventy (70) weather stations are researched in Texas, Oklahoma, Louisiana, Arkansas, Mississippi, and Tennessee. Daily precipitation for each station identifies potential trends in consecutive dry days. Stations were selected for their completeness, longevity, and their proximity to one another. Only stations with five percent or less missing data were allowed. All 70 stations will be analyzed from 1950-2008. Twenty-four stations possess over 100 years of data and will be analyzed. The best geographical indicator for consecutive dry …

Put The Bunny Down, And Other Short Stories, Jacqueline Mersereau Lincoln

LSU Master's Theses

I have always been interested in stories, and parts of every story I have heard has shaped who I am as an adult. If I’m not telling others an anecdote of a moment turned into an adventure, I am inventing adventures to tell myself. Three characters developed from the mixture of the stories I heard from true life, books and television, and what I made up for myself. Originally I simply intended these characters of a little girl, a rabbit, and a few raccoons to interact with one another and show moments of individual stories—like illustrations in an anthology that …

Using Algae To Estimate Postmortem Submersion Interval In A Louisiana Bayou, Sophia Renke

LSU Master's Theses

While algae are often used in forensic science for the determination and confirmation of death by drowning, their utility for the estimation of postmortem submersion interval (PMSI) has been underutilized. Algae are present in all water systems and will grow upon decomposing matter; yet, very little published literature exists on their use in PMSI estimation. Because PMSI is difficult to predict due to the variable nature of water, the reaction of the submerged body within water, and the lack of truly sarcophagous aquatic insects, algae are a potentially invaluable tool for the forensic anthropologist. This research investigates the utility of …

Synoptic Circulation Of The North American Monsoon System And Precipitation Within The Lower Colorado River Basin, Jessie Frances Mccann

LSU Master's Theses

The North American Monsoon System (NAMS) is an important climate phenomenon that affects the southwestern United States during the warm season, most significantly in July and August. Climatic variability associated with the NAMS impacts a wide range of both physical and socio-economic systems in this region, with a broad range of stakeholders concentrated in the Lower Colorado River Basin (LCRB) that includes portions of five southwestern states. This study examines variations in synoptic circulation patterns associated with the NAMS with respect to the LCRB. Using a manual classification, daily 500-mb geopotential height patterns were classified for monsoon seasons (July 1-September …

The Role Of Daily Routines In Adolescents Diagnosed With Attention-Deficit/Hyperactivity Disorder, David N. Landry

LSU Doctoral Dissertations

Researchers consistently report both immediate and long-term benefits of establishing daily routines during childhood (e.g., increased physical health, medical treatment adherence, homework completion, and family communication). Increasing routines is also an essential component of evidence-based treatment programs for childhood externalizing problems (i.e., impulsivity, hyperactivity, and noncompliance). Research indicates that ADHD children respond particularly well to the regularity and predictability offered by daily routines. However, relatively few studies have examined the role that routines play on the adjustment and development of adolescents. In part, this is due to the lack of assessment tools available that specifically measure adolescent routines. The Adolescent …

Western Interpretation Of The Other: How The Perpetuation Of Negative Stereotypes Against Blacks Have Shaped Our Culture, Katrina M. Andry

LSU Master's Theses

This thesis examines the history and nature of stereotypes propagated against blacks from the African Exploration to present day. Therefore by understanding the nature of these stereotypes one can better understand the consequences they’ve had on the black community and they’ve helped to maintain racism in America. This thesis further investigates the media’s role in maintaining racist attitudes towards blacks and how separating people in categories ranking from superior which consequentially breeds inferiority is advantageous to the majority rule in America. In conclusion the problem presented in this thesis has no concrete solution other than the viewer’s perspective after engaging …

Maladies Of Modernity: Scientism In Politics, David Nathan Whitney

LSU Doctoral Dissertations

This dissertation explores the complex relationship between science and politics. More specifically, it focuses on the problem of scientism. Features of scientism include the dogmatic faith in the methods of the natural sciences (and the accompanying assumption that those methods can be successfully imported into the social sciences), a materialistic worldview, the rejection of the bios theoretikos, the prohibition of philosophical questions, and an emphasis on immanent fulfillment through the power of science. I seek to demonstrate that scientism is intellectually impoverishing and politically dangerous. Given the lack of full-length studies on the subject, I trace the development of scientism …

The Power Struggle Between Americans And Creoles In The First Half Of The Nineteenth Century And Its Influence On The Architecture Of New Orleans, Sylvia Starns Mince

LSU Doctoral Dissertations

In the first half of the nineteenth century the house types of the landscape and the footprint of New Orleans changed dramatically. Many of the changes can be attributed to the influx of the refugees from Saint Domingue and the Americans who immigrated from the North and the East Coast of the United States. Both sets of influxes reflect the impact of these two immigrant groups on the previously existing power structures in economics, politics, and society of the city. While the refugees from Saint Domingue more or less assimilated into the city, and in doing so, achieved power over …

1337 W4yz Of {Dollar}P34king: Toward A Unifying Pragmatic Theory Of Virtual Speech Community Building, Tracy Rene Leblanc

LSU Doctoral Dissertations

Building a speech community requires building a shared history of communicative interaction. Within a virtual medium, speech community members employ accommodations for the lack of shared physical space that face-to-face interactions provide. These accommodations, amassing through extended discourse, bring to light the communicative strategies that virtual interlocutors employ in order to build community. Drawing from a corpus of unscripted, naturally occurring discourse of a particular virtual speech community, I engage three frames of linguistic analysis in order to recognize the communicative strategies that constitute speech community building. Relevance Theory (Sperber and Wilson 1995) accounts for the individual cognitive work involved …

Phylogeny Of The Macaques (Cercopithecidae: Macaca) Based On Alu Elements, Jing Li, Kyudong Han, Jinchuan Xing, Heui Soo Kim, Jeffrey Rogers, Oliver A. Ryder, Todd Disotell, Bisong Yue, Mark A. Batzer

Faculty Publications

Genus Macaca (Cercopithecidae: Papionini) is one of the most successful primate radiations. Despite previous studies on morphology and mitochondrial DNA analysis, a number of issues regarding the details of macaque evolution remain unsolved. Alu elements are a class of non-autonomous retroposons belonging to short interspersed elements that are specific to the primate lineage. Because retroposon insertions show very little homoplasy, and because the ancestral state (absence of the SINE) is known, Alu elements are useful genetic markers and have been utilized for analyzing primate phylogenentic relationships and human population genetic relationships. Using PCR display methodology, 298 new Alu insertions have …

Race And Ancestry In Biomedical Research: Exploring The Challenges, Timothy Caulfield, Stephanie M. Fullerton, Sarah E. Ali-Khan, Laura Arbour, Esteban G. Burchard, Richard S. Cooper, Billie Jo Hardy, Simrat Harry, Robyn Hyde-Lay, Jonathan Kahn, Rick Kittles, Barbara A. Koenig, Sandra S.J. Lee, Michael Malinowski, Vardit Ravitsky, Pamela Sankar, Stephen W. Scherer, Béatrice Séguin, Darren Shickle, Guilherme Suarez-Kurtz, Abdallah S. Daar

Faculty Publications

The use of race in biomedical research has, for decades, been a source of social controversy. However, recent events, such as the adoption of racially targeted pharmaceuticals, have raised the profile of the race issue. In addition, we are entering an era in which genomic research is increasingly focused on the nature and extent of human genetic variation, often examined by population, which leads to heightened potential for misunderstandings or misuse of terms concerning genetic variation and race. Here, we draw together the perspectives of participants in a recent interdisciplinary workshop on ancestry and health in medicine in order to …

The Role Of Black Barbudans In The Establishment Of Open-Range Cattle Herding In The Colonial Caribbean And South Carolina, Andrew Sluyter

Faculty Publications

Some significant problems remain in understanding the establishment of open-range cattle herding in the Caribbean and North America, especially regarding the role of blacks in that process. Research to date has identified the Greater Antilles, especially Spanish Cuba and British Jamaica, as the sole Caribbean sources of settlers who established the herding systems of, respectively, Mexico and South Carolina. Yet an open-range cattle herding system also occurred in the British Lesser Antilles, which provided many of the settlers for the South Carolina colony. Archival and field research in Antigua and Barbuda provide the basis for comprehensive reconstruction of that system’s …

Moving Over Mountains: A Woman On The Appalachian Trail, Jessica Susan Matthews

LSU Master's Theses

This project examines the experience of a woman on the Appalachian Trail. It is my aim in undertaking this project to evaluate my own personal experiences in order to explore the way the Appalachian Trail is conceptualized as a space, and then experienced as a place. My own experiences will be connected to and contrasted by experiences I have with other hikers. It is through my own experiences and those of others that I hope to highlight the ways that spaces and mobilities are gendered in our society and the ways that those expectations are usurped. The wilderness might be …

Heidegger And Dewey: Science In A Post-Metaphysical World, Michael Allen Dusch

LSU Master's Theses

The aim of this paper is to compare and contrast the philosophies of Martin Heidegger and John Dewey regarding metaphysics and science. Concerning metaphysics, there are two main areas of attention, the historical emergence of metaphysics in the philosophical tradition, and the abandonment of the metaphysical notions of substance and subjectivity. After examining these two areas of both thinkers’ philosophies, we then turn to their philosophy of science, demonstrating how the scientific thought of both thinkers is inseparable from their metaphysical critiques. For Heidegger, modern science is merely a continuation of the metaphysics of the past, while for Dewey; science …

These Savages Are Called The Natchez: Violence As Exchange And Expression In Natchez-French Relations, Kathrine Seyfried

LSU Master's Theses

Culture contact in colonial North America sometimes led to violent interactions. The continent during colonization contained two very different populations. Native Americans and Europeans occupied the same space and necessarily developed unique relationships. Each had to maneuver around the other to forge careful and productive bonds. When they could not, conflict arose; sometimes as war, sometimes as stealing or raiding. During their brief relationship, the Natchez Indians and French colonists in Louisiana engaged in several wars. Those wars revealed various elements of each culture. In 1716 Natchez warriors responded to a French diplomatic insult by killing French fur traders travelling …

Estimating Age At Death By Examining The Crystallite Size Of Hydroxylapatite In Human Teeth, Teresa Veronica Wilson

LSU Master's Theses

Estimation of age is an important component of the biological profile that forensic anthropologists construct in order to attain a positive identification of a deceased individual. This research is a proof of concept study for the use of X-ray diffraction (XRD) on a tooth sample to estimate age. Previous research (Meneghini et al. 2003; Hanschin and Stern 1992) has concluded that the crystallite size of bone will increase with increased age. The feasibility of the use of teeth in XRD analysis was first tested using pig teeth (samples P1, P2, and P3). Another set of pig teeth (PC1, PC2, and …

The Context And Function Of Four Exceptions To Effigial Wall Tomb Patronage In Quattrocento Florence, Katy Gail Richardson

LSU Master's Theses

Entitlement to burial in a wall tomb with sculpted effigy, the Florentine tomb-type above all others in honor and prestige, belonged solely to members of the ecclesiastical elite throughout the Trecento and into the Quattrocento, but that changed in the mid-1440s with the inclusion of the most illustrious laymen among those memorialized by this type of monument. This modification of patronage, however, does not signify a major reform that allowed unmitigated access to the tomb-type for all laymen of high repute. On the contrary, eighteen of the twenty-two known effigial wall tombs erected in Florence in the fourteenth and fifteenth …

Essays On The Integration Of Anisotropic Landscapes Within Contemporary Geographic Profiling Models, Joshua D. Kent

LSU Doctoral Dissertations

A criminal geographic profile is a tool used by law enforcement professionals for estimating the probable location of a serial offender’s anchor point, or domicile. This estimate is constructed according to the distribution of linked crime scenes. While this approach can utilize a number of different modeling techniques, most fail to account for the inherent irregularities of the physical and cultural landscape. Contemporary methodologies have consistently adopted the a priori assumption that an offender’s crime scenes and anchor point are located across an isotropic surface on which the opportunity to offend is equally distributed around the offender’s residence. Simple introspection …

Assessing The Accuracy Of Task Time Prediction Of An Emerging Human Performance Modeling Software - Cogtool, Oluwakemi Damilola Adio

LSU Master's Theses

There is a need for a human performance modeling tool which not only has the ability to accurately estimate skilled user task time for any interface design, but can be used by modelers with little or no programming knowledge and at a minimal cost. To fulfill this need, this research investigated the accuracy of task time prediction of a modeling tool – CogTool - on two versions of an interface design used extensively in the petrochemical industry – DeltaV. CogTool uses the KeyStroke Level Model (KLM) to calculate and generate time predictions based on specified operators. The data collected from …

A Social Vulnerability-Based Genetic Algorithm To Locate-Allocate Transit Bus Stops For Disaster Evacuation In New Orleans, Louisiana, Xiaojun Qin

LSU Master's Theses

In the face of severe disasters, some or all of the endangered residents must be evacuated to a safe place. A portion of people, due to various reasons (e.g., no available vehicle, too old to drive), will need to take public transit buses to be evacuated. However, to optimize the operation efficiency, the location of these transit pick-up stops and the allocation of the available buses to these stops should be considered seriously by the decision-makers. In the case of a large number of alternative bus stops, it is sometimes impractical to use the exhaustive (brute-force) search to solve this …
