Atlantic Tropical Cyclone: Climatology And The Contribution To Monthly And Seasonal Rainfall In The Eastern U.S. 1960-2007, Ricardo Chabarria Nogueira

LSU Doctoral Dissertations

Tropical cyclones (TCs) are among the most devastating of natural disasters, producing high winds, heavy rainfall, and floods. When TC remnants are considered, these events have impacts nearly nationwide across the U.S. Tropical cyclone activity in the North Atlantic Basin experiences great variability on intra-annual, interannual, and interdecadal timescales. That variability is often associated with El Niño Southern Oscillation (ENSO) and Atlantic Multidecadal Oscillation (AMO). George Cry (1967), in his pioneering study of tropical cyclone-induced rainfall found that TC rainfall presents an intraseasonal pattern over the eastern Unite States, contributing up to 40% of the monthly rainfall. This study replicates …

Sediment Records Of Modern And Prehistoric Hurricane Strikes In Weeks Bay, Alabama, Yun Huang

LSU Master's Theses

This study aims to find modern and prehistoric hurricane records in sediment from marsh and swamp forest surrounding Weeks. Hurricane Ivan made landfall in this area at category 3 intensity in 2004. Hurricane Katrina and Hurricane Frederic also seriously affected this region in 2005 and 1979, respectively. Seventy two cores were taken from marshes, swamps, and bay bottom. The cores, taken from baymouth marsh, contain a prominent Ivan sand layer, and possibly a prominent Frederic sand layer as well. For those cores taken from the marshes and swamps around the eastern, western, and northern Weeks Bay, there is no distinct …

A Multi-Proxy Approach To Investigating The Latest Holocene (~4,500 Yrs. Bp) Vegetational History Of Catahoula Lake, Louisiana, Rebecca Ann Tedford

LSU Doctoral Dissertations

A multi-proxy investigation of sediments examined from Catahoula Lake, Louisiana has provided a record of late-Holocene vegetational changes, related to both hydrology and climate. This study integrates data from phytoliths, pollen, stable isotopes, magnetic susceptibility, and core sediment analysis. A modern phytolith analog assessed the phytoliths production in local plants and their modern soil sample distribution within the established lake vegetation zones. Fifty of the 76 species produced both distinctive and redundant phytoliths. The modern soil sample database indicates that phytoliths produced from both monocotyledon and dicotlyledon plant groups prove useful in distinguishing between forest and grassland communities and identifying …

Descriptive Study Of Korean E-Mail Discourse, Jaegu Kim

LSU Doctoral Dissertations

This study is an examination of a corpus of computer mediated Korean discourse (i.e., e-mail), based on a folk-cultural category, nunch’i. Nunch’i is actively involved in linguistic feature use in terms of [+age] and [+distance] of human relationships. Many Koreans think that the world has an inherent hierarchy according to age. This idea has been reflected through nunch’i, a culture-specific system for maintaining harmonious social relationships especially between [+age] and [–age] people. Nunch’i has a function of foresight, in that it is part of the way that people read the situations and the faces of addressers and addressees. Like oral …

Everyday, Jill Tucker Moore

LSU Master's Theses

In our everyday lives we are bombarded with thousands, even millions, of images. Suffering information overload, we filter out the vast majority of these impressions – the person we pass on the street or sitting in the car next to us at a stop light. We only ‘see’ those people, places and things that ‘matter’, all else becomes ‘noise’; filtered into the background of consciousness – vaguely familiar, yet simultaneously foreign, creating a ‘manageable paradigm’ or construct of the world we inhabit. I take photographic portraits every day. Not of the ‘important’ in my life, but the nondescript, often overlooked …

Structural Influences In Information Systems Projects: A Virtual Experiment In A Multi-Agent System, Pierce Hopkins

LSU Doctoral Dissertations

A virtual experiment (in silico) of a complex social system is conducted in order to investigate the effects of social structure and organizational culture on an information system development project’s outcome. This is performed within the context of user participation and project success. A 2x2 factorial design is employed with the social factor being measured as either low or high initial relationships between the customer and developer groups working on the project. The cultural factor is measured dichotomously with the two groups either having the same or different cultural beliefs. The project success outcome variable is measured as a percentage …

Crop Coefficients For Cotton In Northeastern Louisiana, Sean Allen Hribal

LSU Master's Theses

Daily crop coefficients (Kc) were determined for irrigated cotton (Gossypium hirsutum L.) at the Louisiana State University (LSU) AgCenter Northeast Research Station near St. Joseph, Louisiana, in 2007. Kc values were calculated using daily crop evapotranspiration (ETc), which was measured using paired weighing lysimeters, and daily reference evapotranspiration (ETo), which was calculated using the Standardized Reference Evapotranspiration Equation (SREE) for a short crop. Meteorological data for input into the SREE were obtained from a nearby Louisiana Agriclimatic Information System (LAIS) weather station and an on-site portable weather station. Averaged Kc values were 0.15, 0.64, and 1.39 for the initial (day …

Impact Of Watershed Delineation Detail On Hydrologic Process Modeling In Low Slope Areas, Jason Alexander Braud

LSU Master's Theses

Ascension Parish, located along the Mississippi River in southern Louisiana, is a low-lying, low slope landscape that primarily drains into the tidally-influenced Lake Maurepas. The predominant method of drainage within the parish is gravity drainage. Ascension Parish is currently one of the fastest growing areas in the United States. New developments have changed the area’s hydrology along with its landscape. Proper watershed delineation within the parish is critical for the management of and future improvements to the parish’s drainage infrastructure. Most of the recent drainage modeling in the parish has been performed using a light detection and ranging (LIDAR) digital …

An Analysis Of The Social Networks Of Local Television Reporters, Lisa R. Honore

LSU Doctoral Dissertations

This study analyzed the personal and professional networks of four local television reporters using social network analysis methodology. Network analysis was carried out to the tertiary level allowing examination of demographic data for 773 individuals in the reporter networks. Analysis was conducted through the lens of media norms and routines and the sociological principle of homophily that states people are more likely to associate with people like themselves. Using as a guide, norms and routines and homophily literature as well as studies about the portrayal of minorities, the study examines how the social networks of reporters can determine how communities …

A Taphonomic Model Of Concealment: Decomposition And The Postmortem Interval (Pmi) In A 55-Gallon Barrel, Lauren Rebecca Pharr

LSU Master's Theses

Three 80-pound pigs used as human models were sealed inside 55-gallon black metal drums to monitor the rates and stages of decomposition of concealed, child-sized remains. Visual assessments of the anaerobic decomposition processes in each of the drums for Pigs A and B were possible through a Lexan window installed on each drums’ lid. The third pig—Pig C—was placed inside a drum with four one-half-inch holes permitting insect access and oriented in north, south, east, and west positions around the drum’s upper perimeter. Visual assessments of Pig C were made by lifting the drum’s lid; these assessments revealed that the …

Why The Old Traditions Will Not Fail: Landscape, Legends, And The Construction Of Place At Dartmouth College, Charles H. Wade

LSU Doctoral Dissertations

Dartmouth College, located in Hanover, New Hampshire, is one of the nine Colonial Colleges and a member of the exclusive Ivy League. Congregationalist minister Eleazar Wheelock founded Dartmouth in 1769 on the premise of training missionaries to Christianize the Indians of the region and, over the years, Dartmouth developed into a premier college. Dartmouth is famous for its traditions, its ardently loyal alumni, and as a classic New England liberal arts college. But this image does not correspond with a closer, more critical look at the College. Through both archival and ethnographic research, this dissertation examines the cultural landscape, folklore, …

Strangers In The Postcolonial World, Thomas F. Halloran

LSU Doctoral Dissertations

This dissertation analyzes American writing from and about the former British and French colonies in order to critique postcolonial theory and also to establish a new genre of expatriate literature. Focusing on the works of J. P. Donleavy, Edith Wharton, Paul Bowles, and Paul Theroux, I argue that reading these Americans disrupts the binary concepts encouraged by postcolonial theory. This project rethinks important dichotomies such as colonizer/colonized, center/margin, metropolis/margin, civilized/primitive, and white/non-white by examining the ambiguous American character in the postcolonial context. I argue that by categorizing the themes of American literature in the colonies, and analyzing the similarities and …

A Sense Of Community And Community Change: An Ethnographic Study Of A Contemporary Louisiana Juke Joint As It Compares To Historical Literature On The Subject, Kristopher Ian Debnam

LSU Master's Theses

The rural juke joint is a phenomenon that has been mentioned quite frequently in literature pertaining to blues music, but has not received the amount of scholarly attention that it deserves. This social institution is an integral part of the Mississippi Delta’s cultural landscape. Over time, it has developed a dual reputation as a fun place for weekend entertainment, and also a dangerous place for sin and vice. Using qualitative methods, this thesis explores a modern-day juke joint located in Waterproof, Louisiana, a small town in the northeast part of the state. It is the goal of this research to …

Putting A Face On Prehistory: Reconstructing Late-Mississippian Faces, Alicia Canfield

LSU Master's Theses

This paper examines the results of artificial cranial deformation on the human skull in relation to the human face and the use of three-dimensional printing in the making of skull casts. Forensic facial reconstructions, following the American Method, were performed on three Native American skulls from the Late-Mississippian period, excavated from the Humber Site and on loan from the University of Southern Mississippi, in order to see whether or not the artificial deformation radically changed the faces of the individuals. Skull casts were made out of ABS plastic using rapid prototyping technology, as the original skulls were too fragile for …

Culture And Persuasion Online: Predicting Attitudes, Cognitions, And Behavioral Intentions In A Culturally Diverse Online Marketplace, Gennadi Gevorgyan

LSU Doctoral Dissertations

With an online experiment and a focus group, I examined the role of cultural appeals in online persuasive communication. The results of the study revealed that culturally oriented Web sites and online advertisements influence individual attitudes and behavioral intentions. These effects were particularly strong when cultural appeals were consistent across advertisements and their hosting Web sites. I observed the main effect of culture on persuasiveness of Web sites and advertisements both the American and the Chinese samples of participants. The results of the study did not, however, support the expectation that ethnic identity and need for cognition would interact with …

Strutting It Up Through Histories: A Performance Genealogy Of The Philadelphia Mummers Parade, Corey Elizabeth Leighton

LSU Doctoral Dissertations

This study examines the cultural performances of the parade community in one of the oldest and largest parades in the country: the Philadelphia Mummers Parade. The modern parade celebration consists of groups of mostly working-class white men from South Philadelphia who dress up in extravagant sequined and feathered costumes and, beginning in South Philadelphia, march toward City Hall on one of the largest streets in the city on New Year’s Day. The parade is competitive and marked by performance competitions at the end of each parade. The parade’s history in the city of Philadelphia is extensive but contested. Many locals …

"Why Do I Have Fifty Pairs Of Shoes?": Characterizing And Explaining Acquisitive Buying Behavior, Mousumi Bose Godbole

LSU Doctoral Dissertations

Why do some of us have the fourteenth black shoe? Fifty pens? Thirty fishing rods? While some motivations relate to compulsive, impulsive or excessive buying, others relate to collecting, hoarding, fixated buying and stockpiling. However, there is a set of consumers who purchase recurrently, have an inventory far greater than that of a typical consumer and yet do not share the negative characteristics of the extreme buyers mentioned earlier. This set of consumers is termed ‘acquisitive buyers’ and little research exist to understand them. This dissertation establishes the significance of acquisitive buying as a new buying type in terms of …

Proxy Records Of Paleohurricanes For The Western And Southern Caribbean, Terrence Allen Mccloskey

LSU Doctoral Dissertations

This dissertation evaluates the hypothesis that hurricane activity levels in the North Atlantic during the late Holocene have been driven by latitudinal movements of the North Atlantic circulation system. Multi-millennial sedimentary proxy records, based on the occurrence of overwash clastic layers, provide clear evidence of abruptly alternating periods of hurricane landfall frequency for Nicaragua and Belize. Three Belizean transects exhibit an Active period (hyperactivity) occurring from ~2000-6000 cal yr BP, although dating is inconsistent across the transects. An Active period covering the last 500 years is found at one location. The Nicaraguan record, derived from three transects covering >90 km …

"It Takes A Lot Out Of You": Ethnography Of Secondary English Teachers' Writing Pedagogy, Lisa F. Morales

LSU Doctoral Dissertations

This study was conducted in two case-study teachers’ public middle school classrooms in south Louisiana and a survey in three public school districts. A qualitative research focus with the research design taken from work of Michael Patton’s (2002) Qualitative Research Evaluation Methods and James Spradley and David McCurdy’s (1975) Anthropology: The Cultural Perspective. The survey was developed from the work of Tourangeau, Rips, and Rasinski’s (2002) The Psychology of Survey Responses. The researcher assumed the role of participant observer for three months which resulted in two themes: first, traditional teaching methods in the teaching of writing, and secondly, teacher perceptions …

An Integrated Agent-Based Microsimulation Model For Hurricane Evacuation In New Orleans, Wei Liang

LSU Doctoral Dissertations

Mass evacuation of urban areas due to hurricanes is a critical problem that requires extensive basic and applied research. Knowing the accurate evacuation time needed for the entire region in advance such that the evacuation order can be issued on a timely basis is crucial for the officials. Microsimulation modeling, which focuses on the characteristics of individual motorists and travel behavior, has been used widely in traffic simulation as it can lead to the most accurate result. However, because detailed driver response modeling and path processing must be incorporated, vehicle-based microscopic models have always been used only to simulate small …

Public Opinion And The Katrina Disaster: Linking Support For Rebuilding And Perceptions Of Flood Victims In New Orleans, Vincenzo Pasquantonio

LSU Master's Theses

Public support for government assistance to the needy has long been the focus of scholarly attention. Some assert that the perceived race of recipients of such aid is the primary determinant influencing such support. Others cite that it is the degree of trust one has in government institutions while still others cite American notions of individualism and self-reliance versus collective responsibility. The present study analyzes public opinion regarding aid to the City of New Orleans and its inhabitants following Hurricane Katrina and the subsequent flooding of the city. Several important findings emerge from this analysis. First, it cannot be demonstrated …

Miocene Herpetofaunas From The Central Gulf Coast Usa: Their Paleoecology, Biogeography, And Biostratigraphy, Michael John Williams

LSU Doctoral Dissertations

The late Barstovian Fort Polk herpetofauna represents the most diverse herpetofauna on the Gulf Coast, USA, and includes 15 genera from ten families. The herpetofaunal composition of Fort Polk and Miocene east Texas localities is similar enough to Great Plains localities that they are all considered to be one biogeographical province during the Barstovian. The use of ternary diagrams, ratios of herpetological elements to kg matrix screened, and natricine-colubrine indices, has allowed determining the wetness of the Fort Polk sites. Development of a composite stratigraphic section for North American fossil snakes has allowed recognition of two extinctions of fossil snakes …

Cbod₅ Treatment And Nitrogen Transformations Of The Marshland Upwelling System In Intermediate And Saltwater Marshes, Lorna Anne Putnam

LSU Doctoral Dissertations

The marshland upwelling system (MUS) was designed to treat domestic wastewater from coastal dwellings where conventional methods are inadequate due to high water tables, poor hydraulic soil conditions, anaerobic soils, and saline groundwater. Currently there is no adequate treatment system available and coastal dwellings are contributing to water quality problems. This study focused on determining the treatment effectiveness of the MUS for organic matter and understanding the specific processes involved in nitrogen treatment.

The treatment of organic matter, measured as five-day carbonaceous biological oxygen demand (CBOD₅), was effective in field tests for both saltwater and intermediate marshes. Global …

Turn-Taking And Gaze Behavior Among Cajun French And Cajun English Speakers In Avoyelles Parish, Andrew Mandell Riviere

LSU Master's Theses

Languages are the verbal and non-verbal codes of a culture. A culture houses a language(s) and is comprised of the gaze and distance/use of personal sphere. Linguists and anthropologists have long since argued over which takes priority: culture or language. French and Louisiana are synonymous: it is unimaginable to picture Louisiana without French because French constitutes the culture in Louisiana. Since linguists have debated the priority of language or culture, looking at Louisiana within the confines of this debate proves informative.

The language shift forced upon the residents of South Louisiana by the 1921 State Legislature made English the sole …

People, Sheep, And Landscape Change In Colonial Mexico: The Sixteenth-Century Transformation Of The Valle Del Mezquital, Richard Hunter

LSU Doctoral Dissertations

The causes of central Mexico’s environmental degradation are poorly understood. Scholarly contention centers on the role of introduced livestock as agents of soil erosion. This dissertation explores New Spain’s sixteenth-century livestock ecology by drawing upon archival and field data to reconstruct the spatio-temporal characteristics of sheep ranches in a southeastern section of central Mexico’s Valle del Mezquital. The introductory chapter outlines a scholarly disagreement from the 1990s that underscored differences between historical and geographical approaches to studying historical landscape transformations. On one side of this debate, geographer Karl W. Butzer finds in the sixteenth-century Mexican Bajío little evidence for environmental …

Field Measurements Of Influence Of Sand Transport Rate On Structure Of Wind-Sand Flow Over Coastal Transverse Ridge, Yuxiang Dong, S. L. Namikas, P. A. Hesp, Jun Ma

Faculty Publications

The structure of wind-sand flow under different total sand transport rates was measured with field vertical anemometer and sand trap on the crest of typical coastal transverse ridge in Changli Gold Coast of Hebei Province, which is one of the most typical coastal aeolian distribution regions in China and famous for the tall and typical coastal transverse ridges. The measurement results show that, on the conditions of approximate wind velocities and same surface materials and environments, some changes happen to the structure of wind-sand flow with the increase of total sand transport rate on the crest of coastal transverse ridge. …
