Solving A Locational Distribution Problem Of Non-Toxic Solid Waste On The Island Of Puerto Rico, Sandra A. Soto Jan 2004

Solving A Locational Distribution Problem Of Non-Toxic Solid Waste On The Island Of Puerto Rico, Sandra A. Soto

LSU Master's Theses

The island of Puerto Rico is confronting a crisis in waste management due to inadequate management from the local government, the decreasing number of landfills available, high population density, and paucity of places for waste disposal. This research develops a least-cost model for the disposal and transportation of non-hazardous solid waste. Location-allocation (LA) and Geographic Information Systems (GIS) software are used to analyze the efficiency of the present pattern of waste allocation and to identify a near-to-optimal assignment of waste for the landfills in operation today and the landfills that will be open by 2008. The “near-to-optimal” models obtained from …

19th And 20th Century French Exoticism: Pierre Loti, Louis-Ferdinand Cé́Line, Michel Leiris, And Simone Schwarz-Bart, Robin Anita White Jan 2004

19th And 20th Century French Exoticism: Pierre Loti, Louis-Ferdinand Cé́Line, Michel Leiris, And Simone Schwarz-Bart, Robin Anita White

LSU Doctoral Dissertations

This study of four 19th and 20th century colonial texts, as well as a later postcolonial novel exposes the cadres exotiques, or exotic frameworks, of literary exoticism. The thesis names and interprets the moods of and reactions to exoticism, including colonial exoticism, antiexoticism, and autoexoticism. Poetic and theoretical interpretations of exoticism, such as Victor Segalen’s Notion du Divers and Edouard Glissant’s Opacité and Poétique de la Relation challenge the prevalent assumptions that the literary practice was only an unfortunate byproduct of colonialism. The first chapter presents literary history and theoretical considerations relating to exoticism: Orientalism, nostalgia, colonial literary history, and …

An Integrative Model Of Clients' Decision To Adopt An Application Service Provider, Yurong Yao Jan 2004

An Integrative Model Of Clients' Decision To Adopt An Application Service Provider, Yurong Yao

LSU Doctoral Dissertations

Application Services Providers (ASPs) exploit the economics of delivering commercial off-the-shelf software over the Internet to many dispersed users, but the decision-making process to adopt the ASP business model can be complex requiring a comprehensive consideration of various factors. As a new form of outsourcing, the ASP business model differs from traditional outsourcing models with respect to the attributes associated with vendors, clients, and applications. These differences are expected to demand decision models that are distinct from those in the traditional IS outsourcing. In this study, an integrative model for ASP adoption that incorporates economic determinants, strategic determinants, and social …

Hydroclimatic And Circulation Anomalies Associated With The North Atlantic Subtropical High, Brian Taylor Allen Jan 2004

Hydroclimatic And Circulation Anomalies Associated With The North Atlantic Subtropical High, Brian Taylor Allen

LSU Master's Theses

Hydroclimatic and circulation variability in regions around the Atlantic sector are linked to the intensity, location, and areal extent of the North Atlantic subtropical high (STH). Few analyses focus directly on the influence of the STH on climatic variability. Using sea level pressure (SLP) data from the NCEP/NCAR Reanalysis dataset, a time series of the STH was produced using principal components analysis (PCA) to describe the temporal variability of the STH from January 1948 to December 2001. A simple area average of SLP across the PCA domain is shown to describe the same phenomena (the dominant mode of the STH …

Estimation Of Living Body Weight Based On Measurements Of Anterior Superior Iliac Spine Breadth And Stature, Jaime A. Suskewicz Jan 2004

Estimation Of Living Body Weight Based On Measurements Of Anterior Superior Iliac Spine Breadth And Stature, Jaime A. Suskewicz

LSU Master's Theses

Standard identification criteria for creating a decedent’s biological profile typically include ancestry, sex, age, and stature, but not body weight. Body weight information may not only assist in creating a more complete biological profile but may also provide insight into other forensic considerations, such as taphonomy and body transport and disposal. The current study seeks to establish multiple regression equations for the prediction of living body weight in skeletal remains. Specifically, the measurements of anterior superior iliac spine (ASIS) breadth and stature are assessed with regard to living weight. Research was carried out on both a skeletal sample and a …

Flesh And Spirit Onstage: Chronotopes Of Performance In Medieval English Theatre, Gregory Lee Cavenaugh Jan 2004

Flesh And Spirit Onstage: Chronotopes Of Performance In Medieval English Theatre, Gregory Lee Cavenaugh

LSU Doctoral Dissertations

This study uses Mikhail Bakhtin's chronotope, which is the informing principle of one's experience of space and time, to explore different relations among space, time, actors, and audience in medieval theatre. Relations between the material and spiritual worlds as understood in the Middle Ages are considered in the context of relations between performers and audience members with two goals. First, I explore how the ontological status of the metaworld created through performance changed in the context of specific chronotopes. Second, I explore how diverse religious discourses affected medieval modes of representation. This study posits three chronotopes of performance informing medieval …

"Walking The Queen's Highway": Ideology And Cultural Landscape In Nothern Ireland, Deborah J. Miller Jan 2004

"Walking The Queen's Highway": Ideology And Cultural Landscape In Nothern Ireland, Deborah J. Miller

LSU Doctoral Dissertations

The use of public art and ritual in Northern Ireland leads to the creation of cultural landscapes heavy with symbolism – ideological landscapes – that maintain social divisions and incite conflict. Mural and curbstone painting, flag bearing, the construction of memorials, and parading are activities that inscribe messages in the landscape. This study documents the types of symbolism prevalent in Northern Irish landscapes, the meanings attributed to them, and the reactions and subsequent cultural landscape re-creations that result. Loyalist and nationalist marches that incite riots and civil disorder have disrupted and delayed peace efforts in Northern Ireland for decades. Both …

An Application Of Geographic Information Systems (Gis): The Utility Of Victim Activity Spaces In The Geographic Profiling Of Serial Killers, Charles Casey Shamblin Jan 2004

An Application Of Geographic Information Systems (Gis): The Utility Of Victim Activity Spaces In The Geographic Profiling Of Serial Killers, Charles Casey Shamblin

LSU Master's Theses

Today, computer technology is producing new methods of investigation into the complex nature of serial killers; among these are geographic profiles. Yet, due to the lack of proven success, budgetary constraints, and the inherent multifaceted nature of serial murder, these geographic profiles have not been completely embraced by the law enforcement community. Because of this, the academic and law enforcement communities continue to refine and develop new methods to solve serial killer cases. This thesis investigates the possibility of identifying the location of the interaction site of a serial killer and his victims using a commercial geographic information system (GIS) …

Evaluation Of The Impacts Of Hurricane Hugo On The Land Cover Of Francis Marion National Forest, South Carolina Using Remote Sensing, Amit Kulkarni Jan 2004

Evaluation Of The Impacts Of Hurricane Hugo On The Land Cover Of Francis Marion National Forest, South Carolina Using Remote Sensing, Amit Kulkarni

LSU Master's Theses

Hurricane Hugo struck the South Carolina coast on the night of September 21, 1989 at Sullivan’s Island, where it was considered a Category 4 on the Saffir-Simpson scale when the hurricane made landfall (Hook et al. 1991). It is probably amongst the most studied and documented hurricanes in the United States (USDA Southern Research Station Publication 1996). There has been a Landsat TM based Hugo damage assessment study conducted by Cablk et al. (1994) in the Hobcaw barony forest. This study attempted to assess for a different and smaller study area near the Wambaw and Coffee creek swamp. The main …

Being Korean And Being Christian: Identity Making In The Korean Baptist Church Of Baton Rouge In The U.S. Deep South, Hyeon Ju Lee Jan 2004

Being Korean And Being Christian: Identity Making In The Korean Baptist Church Of Baton Rouge In The U.S. Deep South, Hyeon Ju Lee

LSU Master's Theses

The post-1965 generation Korean immigrants in the U.S., who have left their country for betterment of their lives, find themselves unable to acculturate to the U.S. mainstream culture. Although legally Americans, these Koreans strive to hold onto their culture they brought with them. A group of Koreans who belong to this post-1965 immigrant generation in Baton Rouge established a church to share religious and cultural experience while speaking Korean language and sharing Korean food--The Korean Baptist Church of Baton Rouge. The members of the Korean Baptist Church of Baton Rouge ("the Church") create a familial community within Christian and Confucian …

Stepping Out Of Her Place: A New Look At Women's Roles During Selected Wars In U.S. History, Nicole Lynn Bowen Jan 2004

Stepping Out Of Her Place: A New Look At Women's Roles During Selected Wars In U.S. History, Nicole Lynn Bowen

LSU Master's Theses

Women are not included in high school history text books in a meaningful way, thus students are only learning about half of the experiences that shaped our nation. The ways in which history is represented as part of the social studies curriculum in secondary schools must be reconsidered. A history text that does not represent the experiences of women in a meaningful way does not provide a means for young women to "locate themselves in time," or meet many of the other standards of the National Council for the Social Studies. If young women and men are going to develop …

What Do Tin-Enameled Ceramics Tell Us?: Explorations Of Socio-Economic Status Through The Archaeological Record In Eighteenth-Century Louisiana: 1700-1790, Jason A. Emery Jan 2004

What Do Tin-Enameled Ceramics Tell Us?: Explorations Of Socio-Economic Status Through The Archaeological Record In Eighteenth-Century Louisiana: 1700-1790, Jason A. Emery

LSU Master's Theses

This thesis examines the presence and distribution of tin-enameled earthenwares in what was colonial Louisiana at nine archaeological sites: Madame John's Legacy (16OR51), the ca. 1730s French Colonial Barracks (16OR136), the Lower Pontalba Building (16OR209), Galveztown (16AN39), French Site I (16PC80), the Bicentennial Gardens (22AD999), Los Adaes (16NA16), the American Cemetery (16NA67), and the Chamard House site (16NA100). To examine the ceramic diversity, a comprehensive classificatory system is proposed, with discussion and classification of vessel forms. Ceramic diversity was anticipated to be patterned following geographic and economic lines; however, this was not substantiated through the analysis of the general body …

Geography, Coloration And Speciation In A Genus Of Neotropical Reef Fishes (Gobiidae: Elacatinus), Michael S. Taylor Jan 2004

Geography, Coloration And Speciation In A Genus Of Neotropical Reef Fishes (Gobiidae: Elacatinus), Michael S. Taylor

LSU Doctoral Dissertations

Studies of speciation in the marine environment have historically compared broad-scale distributions and presumed larval dispersal to infer the geographic barriers responsible for allopatric speciation. However, many marine clades show high species diversity in geographically restricted areas where barriers are not obvious and larval dispersal should bring sister taxa into contact. Genetic differentiation at spatial scales <1000 km could facilitate speciation by mechanisms other than the gradual accumulation of reproductive isolation during extended allopatry, such as ecological adaptation to local environmental conditions or the rapid evolution of genes tied to mate recognition. The role of each of these possibilities has not been simultaneously explored for any species-rich marine taxon. The most species-rich genus of Neotropical reef fishes is Elacatinus (Gobiidae), with 27 species. I examine potential mechanisms underlying this richness through analyses of three genetic markers to investigate genetic and ecological differentiation between closely related taxa and among island populations. Phylogenetic analyses indicate that sister taxa of Elacatinus occur within the same oceans but occupy geographically separate ranges. Sister taxa usually differ by coloration, and distantly related sympatric species frequently differ by habitat. These differences suggest that some combination of coloration and ecological differences may facilitate assortative mating in sympatry or at range boundaries. The ranges of several Elacatinus taxa adjoin at Mona Passage and in the central Bahamas, both in the Caribbean Sea. These boundaries separate island populations by as few as 23 km, yet these populations are genetically distinct. Populations not separated by these breaks also show strong genetic structuring. Coalescent analyses suggest these populations have been demographically closed for up to 800,000 years. Such strong genetic structuring suggests that pelagic larvae are retained at natal populations, despite a three week larval duration (determined from otolith growth rings). My results suggest that local retention of pelagic larvae, coupled with biogeographic breaks, has generated or maintained strong genetic population structure which may facilitate adaptation to local ecological conditions. Such adaptations may explain observed divergence along ecological and coloration gradients. Repeated radiations among allopatrically distributed sister taxa may explain much of the high diversity in Elacatinus.

Herbivore Movement And Spatial Population Dynamics In A Heterogeneous Landscape, Kyle Jonathan Haynes Jan 2004

Herbivore Movement And Spatial Population Dynamics In A Heterogeneous Landscape, Kyle Jonathan Haynes

LSU Doctoral Dissertations

To date, few metapopulation studies have isolated the effects of the intervening matrix from other attributes of landscape structure (e.g., patch geography or quality) that might influence dispersal among patches. Furthermore, there has been little exploration of the mechanisms underlying effects of the matrix on the spatial ecology of species. In this dissertation, I examine how the movement and distribution of the planthopper Prokelisia crocea within and among host-plant patches (prairie cordgrass, Spartina pectinata) is affected by the composition of the matrix (the invasive grass smooth brome [Bromus inermis], native non-host grasses, or mudflat). First, using a mark-recapture study in …

Pan African Narratives: Sites Of Resistance In The Black Diaspora, Anita Louise Harris Jan 2004

Pan African Narratives: Sites Of Resistance In The Black Diaspora, Anita Louise Harris

LSU Doctoral Dissertations

Africa as a point of reference for Africans dispersed from her shores and their descendants in the Diaspora has perpetuated discourse of longing and ambivalence. For centuries these various sentiments have emerged in Black literary expressions. The quest of this study is to advance Black narrative tradition by proposing a theoretical framework informed by these constructs and predicaments to establish a genre of literature referred to here as Pan African narratives. This work looks at Black response to the dilemma of dispersal and dislocation in the Diaspora from the nineteenth to the twentieth century. More specifically, it examines the emergence …

I-Tal Foodways: Nourishing Rastafarian Bodies, Mandy Garner Dickerson Jan 2004

I-Tal Foodways: Nourishing Rastafarian Bodies, Mandy Garner Dickerson

LSU Master's Theses

This thesis takes a close look at the lived world of Jamaican Rastafarians through the lens of food-related practices and preferences, working to define the group's characteristic strategies for maintaining wellness and illuminating their tastes and sensibilities. It strives to evoke a sensorial and discursive awareness of the activities through which Rastafarians nourish and heal their physical and social bodies, by focusing on ways in which they produce and use I-tal food-medicines. Rastafarian taste for I-tal has developed alongside collective engagement with the valorization and revitalization of traditional knowledge about health and land use. In addition to providing sites for …

Martin Heidegger, Emmanuel Levinas, And The Politics Of Dwelling, David James Gauthier Jan 2004

Martin Heidegger, Emmanuel Levinas, And The Politics Of Dwelling, David James Gauthier

LSU Doctoral Dissertations

The late modern and postmodern theme of homecoming permeates the philosophy of Martin Heidegger, who grapples with the topic throughout the various phases of his lifelong meditation on Being. Heidegger continually gave thought to the relationship between Being and the place or site in which it becomes manifest, whether it is a system of references and manipulable entities (Being and Time), language (An Introduction to Metaphysics), or aesthetic works of art (“The Origin of the Work of Art”). Taking as its point of departure Heidegger’s persistent and dynamic search for home (Heimat), this study will examine the political implications of …

The Myth Of Eternal Preservation: Patterns Of Damage In Egyptian Mummies, Ellen Salter-Pedersen Jan 2004

The Myth Of Eternal Preservation: Patterns Of Damage In Egyptian Mummies, Ellen Salter-Pedersen

LSU Master's Theses

Mummification can preserve a body for several millennia, but it is a popular misconception that these bodies are in pristine condition. The activities of tomb robbers, archaeological excavation and transportation, and the embalming process itself may damage the body. This thesis examines published reports on Egyptian mummies from museums in the United States, Europe, and Egypt for the presence of osteological fractures, dislocations and other related damage. These reports include biographical information and the results of investigations made by one or more of the following techniques: unwrapping, autopsying, x-raying, and CT-scanning. Data on 275 Egyptian mummies were collected and examined …

"Never Could Read No Road Map": Geographic Perspectives On The Grateful Dead, Daniel R. Culli Jan 2004

"Never Could Read No Road Map": Geographic Perspectives On The Grateful Dead, Daniel R. Culli

LSU Master's Theses

The Grateful Dead hold a unique niche in the musical, social, and cultural history of the United States. However, while the volume of available academic literature concerning the band is increasing, the Grateful Dead remain to be nearly ignored by academia and, to this point apparently, completely ignored by cultural geographers. This paper introduces the Grateful Dead into the field of geography. I analyze the geography of certain aspects of the band, such as its context in San Francisco, the carnival atmosphere of the entire phenomenon, the over 2300 tour dates, as well as the huge catalog of lyrics sung …

Routes Of Freedom: Slave Resistance And The Politics Of Literary Geography, Judith Louise Kemerait Jan 2004

Routes Of Freedom: Slave Resistance And The Politics Of Literary Geography, Judith Louise Kemerait

LSU Doctoral Dissertations

This dissertation integrates rhetorical, historical, and spatial analysis in an effort to expand our understanding of the cultural work performed by antebellum narratives that take slavery in the United States as their subject matter. Specifically, it focuses on the complicated relationship between place and human praxis as revealed in five texts: The Confessions of Nat Turner, Harriet Beecher Stowe’s Dred, Martin R. Delany’s Blake, Frederick Douglass’s “The Heroic Slave,” and Herman Melville’s Benito Cereno. In my attention to literary geographies, I trace spatial patterns in which considerations of organized resistance and slave rebellion are repeatedly placed in “wild-spaces” such as …

Phylogenetic Influence Of Complex, Evolutionary Models: A Bayesian Approach, Neeraja M. Krishnan Jan 2004

Phylogenetic Influence Of Complex, Evolutionary Models: A Bayesian Approach, Neeraja M. Krishnan

LSU Master's Theses

Molecular evolution recovers the history of living species by comparing genetic information, exploring genome structure and function from an evolutionary perspective. Here we infer substitution rates and ancestral reconstructions, to better understand mutation responses to some known biochemical phenomena. Mutation processes are commonly inferred using parsimony, maximum likelihood and Bayesian. Parsimony is not explicitly model-based, and is statistically biased due to unrealistic assumptions. The model-based maximum likelihood approaches become computationally inefficient while analyzing large or high-dimensional datasets, leaving little opportunities to incorporate complex evolutionary models. We implemented a posterior probability (Bayesian) approach that evaluates evolutionary models, applying it to primate …

Methods For Estimating Long-Distance Dispersal, Ran Nathan, Gad Perry, James T. Cronin, Allan E. Strand, Michael L. Cain Nov 2003

Methods For Estimating Long-Distance Dispersal, Ran Nathan, Gad Perry, James T. Cronin, Allan E. Strand, Michael L. Cain

Faculty Publications

Long-distance dispersal (LDD) includes events in which propagules arrive, but do not necessarily establish, at a site far removed from their origin. Although important in a variety of ecological contexts, the system-specific nature of LDD makes "far removed" difficult to quantify, partly, but not exclusively, because of inherent uncertainty typically involved with the highly stochastic LDD processes. We critically review the main methods employed in studies of dispersal, in order to facilitate the evaluation of their pertinence to specific aspects of LDD research. Using a novel classification framework, we identify six main methodological groups: biogeographical; Eulerian and Lagrangian movement/redistributional; short-term …

Pelvic Sexual Dimorphism In A Metatherian, Didelphis Virginiana: Implications For Eutherians, Robert G. Tague Nov 2003

Pelvic Sexual Dimorphism In A Metatherian, Didelphis Virginiana: Implications For Eutherians, Robert G. Tague

Faculty Publications

Eutherians give birth to relatively large infants. Females have larger pelves than males, though males typically have larger nonpelvic bones. Pelvic dimorphism is an adaptation for parturition. Metatherian females, who give birth to markedly small infants, should not show pelvic adaptations for parturition and should have smaller pelves than males. Adult females and males of the Virginia opossum, Didelphis virginiana, are compared. Males are significantly larger than females in absolute size for 14 of 16 pelvic and 8 nonpelvic measures. Sexes did not differ significantly for lower iliac length and posterior space of midplane. However, relative lengths for females are …

Advances In Satellite Radiometry For The Surveillance Of Surface Temperatures, Ocean Eddies And Upwelling Processes In The Gulf Of Mexico Using Goes-8 Measurements During Summer, Nan Walker, Soe Myint, Adele Babin, Alaric Haag Aug 2003

Advances In Satellite Radiometry For The Surveillance Of Surface Temperatures, Ocean Eddies And Upwelling Processes In The Gulf Of Mexico Using Goes-8 Measurements During Summer, Nan Walker, Soe Myint, Adele Babin, Alaric Haag

Faculty Publications

GOES-8 satellite infrared (IR) measurements have been under-utilized in oceanographic research, although they provide several advantages over measurements from other sensors such as the NOAA AVHRR. Frequent coverage (48 times/day) over large regions, low noise in the mid- IR channel, and sole use of nighttime data have enabled the development of improved techniques for producing "de-clouded" images and calculating accurate SSTs (with RMS errors < 0.5°C), over cloudy and humid regions such as the Gulf of Mexico. Animations of SST composite images reveal movements of the Loop Current, its frontal eddies and coastal upwelling even during summer months. GOES-12 and future GOES imagers for the next decade are missing the 12 μm channel; however, this study demonstrates that the mid-IR channel is even more useful than previously thought.
