The Third Way: A Study Of Economic Justice In The Writings Of Karol Wojtyla (Pope John Paul Ii)., Woodard King Mott Jr
The Third Way: A Study Of Economic Justice In The Writings Of Karol Wojtyla (Pope John Paul Ii)., Woodard King Mott Jr
LSU Historical Dissertations and Theses
Pope John Paul II, born Karol Wojtyla, has written extensively about the human person and how that person acts in the world. Beginning with Wojtyla's doctoral dissertation presented at the Pontifical University of St. Thomas Aquinas on the Catholic mystic St. John of the Cross and continuing through the most recent best seller, Crossing the Threshold of Hope, Christian personalism has pervaded Wojtyla's writings, encyclicals, and public utterances. Wojtyla's perspective on economic justice, as shaped by his Christian personalism, is the subject of this dissertation. A systematic investigation of Wojtyla's theory of economic justice reveals a third way of economic …
Land/Water Interface Delineation Using Neural Networks., Rajabhushanam Cherukuri
Land/Water Interface Delineation Using Neural Networks., Rajabhushanam Cherukuri
LSU Historical Dissertations and Theses
The rapid decline in acreage of land areas in wetlands caused by frequent inundations and flooding has brought about an increased awareness and emphasis on the identification and inventory of land and water areas. This dissertation evaluates three classification methods--Normalized Difference Vegetation Index technique, Artificial Neural Networks, and Maximum-Likelihood classifier for the delineation of land/water interface conditions using Landsat-TM imagery. The effects of three scaling algorithms, including resampling by aggregation, Gaussian smoothing, and local variance analysis, on the classification accuracy are analyzed to determine how the delineation, quantification and analysis of land/water boundaries relate to problems of mixed pixels, scale …
The Influence Of Violence Upon Academic Achievement Among African American First Time College Students., Diana F. Kelly
The Influence Of Violence Upon Academic Achievement Among African American First Time College Students., Diana F. Kelly
LSU Historical Dissertations and Theses
This study examined the relationship between early exposure to violence--both personal and community--and the later academic achievement of African American first time college students. The study incorporated several variables that were thought to impinge upon the academic achievement process. Specifically, those variables were divided into several groups: background factors (socioeconomic status, high school academic record, personal and community violence exposure), student characteristics (locus of control, educational aspirations and expectations), and university characteristics (campus safety, academic and social integration). Student achievement was measured by students' expected grade point average, as indicated on a student questionnaire. University administrators, professors, and researchers who …
An Investigation Of Consistency Between Theoretical Orientations To Reading And Planning For Reading Instruction: A Three-Year Study., Norma Jean Paris
An Investigation Of Consistency Between Theoretical Orientations To Reading And Planning For Reading Instruction: A Three-Year Study., Norma Jean Paris
LSU Historical Dissertations and Theses
The purpose of this three-year study was to investigate the participants' theoretical orientations to reading over time. By presenting an in-depth description of the thoughts and actions, as related to the research questions, of nine student teachers during their student teaching experience, and again three years later as elementary teachers, this study provided valuable insights into the degree to which a well-defined theoretical orientation to reading is internalized and how it manifests in classroom practices. The research questions that were investigated included the durability of theoretical orientations to reading, consistency between theoretical orientations and planning for reading instruction, and the …
Nature, Culture And Big Old Trees: Human Relationships With Ceiba (Ceiba Pentandra) And Live Oak (Quercus Virginiana) In The Landscapes Of Guatemala And Louisiana., Katharine Anderson
Nature, Culture And Big Old Trees: Human Relationships With Ceiba (Ceiba Pentandra) And Live Oak (Quercus Virginiana) In The Landscapes Of Guatemala And Louisiana., Katharine Anderson
LSU Historical Dissertations and Theses
The ceiba in Guatemala and the live oak in Louisiana are examples of two trees that attain great size and age within the cultural landscape. Humans have adopted both as symbolic trees; they protect, encourage and even plant them. As the trees age, they become historic landmarks, are indicators of important places, and give character to the landscape. Although each tree is native within portions of each study area, both have taken advantage of human disturbance to expand beyond their original habitats. In addition, they have been moved deliberately by humans to new areas well beyond their geographical limits. Other …
Moved By The Spirit: Protestant Diffusion And Church Location In Central America, With A Case Study From Southwestern Honduras., Terri Shawn Mitchell
Moved By The Spirit: Protestant Diffusion And Church Location In Central America, With A Case Study From Southwestern Honduras., Terri Shawn Mitchell
LSU Historical Dissertations and Theses
This dissertation traces the evolution of Protestant missions in Central America from the colonial period to the present, focusing on the agents, direction, and methods of Protestant diffusion as well as the changing criteria for site selection. Chapters are arranged chronologically and progress from the macro-scale, Central America, to the micro-scale, six towns in southwestern Honduras (La Esperanza, Intibuca, Yamaranguila, San Juan, Erandique and Gracias). The chapters dealing with Central America outline when and where different mission boards have worked, as well as the geographical, economic, political and theological considerations driving site selection. The focus then narrows to patterns of …
The Florida Chautauqua As Text: Creating And Satisfying A Disposition To Appropriate Cultural Goods In Northwest Florida., Matthew Albert Beemer
The Florida Chautauqua As Text: Creating And Satisfying A Disposition To Appropriate Cultural Goods In Northwest Florida., Matthew Albert Beemer
LSU Historical Dissertations and Theses
The purpose of this dissertation is to demonstrate that the Florida Chautauqua in De Funiak Springs, Florida, was primarily a commercial venture which pretended to a goal of offering cultural, educational, and religious products. In the Chautauqua's early years, it succeeded because it could exploit the economic and cultural situation. The Assembly tried to create a market for "culture" by developing cultural competencies in potential consumers so that those consumers would "buy" what the Chautauqua could sell. As the situation changed, the Florida Chautauqua, though it tried, could not adapt enough to be viable. To support the argument, I describe …
Personal And Organizational Structure Correlates Of Receptivity And Resistance To Change And Effectiveness In Institutions Of Higher Education., James Sutherland Clarke
Personal And Organizational Structure Correlates Of Receptivity And Resistance To Change And Effectiveness In Institutions Of Higher Education., James Sutherland Clarke
LSU Historical Dissertations and Theses
The purpose of this exploratory study was three-fold. First, a conceptual framework was developed to link innovation and organizational effectiveness in higher education settings through the mediating variables of faculty decision-making deprivation, self-efficacy, organizational efficacy, receptivity to change and resistance to change. Second, original instrumentation was developed to measure faculty receptivity and resistance to change and academic unit head perspectives of their unit's effectiveness. Third, linkages between the variables were examined through the collection and analysis of data using structure equation modeling and appropriate variable comparisons. The sample consisted of all faculty from five traditional academic units at all 59 …
Ephemeral Hinterlands And The Historical Geography Of Trujillo, Honduras, 1525-1950., Taylor E. Mack
Ephemeral Hinterlands And The Historical Geography Of Trujillo, Honduras, 1525-1950., Taylor E. Mack
LSU Historical Dissertations and Theses
The historical geography of Trujillo, Honduras is told through its changing hinterlands. This dissertation uses world systems to approach and understand the historical geography of Trujillo, however, the focus is on this peripheral area of the world system, rather than on the core. The coast of the western Caribbean experiences economic boom and bust cycles. The periodization of Trujillo's historical geography is based on the city's boom and bust periods, using primary documents from archives in Central America and Spain. Trujillo's first boom period lasted from its founding in 1525 until 1550, based on gold exports from the interior. During …
Indigenous Lands In A Developing Region: A Historical Ethnogeography Of The Pech Indians Of Eastern Honduras, With Emphasis On Recent Settlement And Land Use Changes., James Richard Samson
Indigenous Lands In A Developing Region: A Historical Ethnogeography Of The Pech Indians Of Eastern Honduras, With Emphasis On Recent Settlement And Land Use Changes., James Richard Samson
LSU Historical Dissertations and Theses
Since before Spanish Contact, the Pech Indians have occupied a large portion of northeastern Honduras. Like other native American populations, they have suffered significant territorial reductions and cultural alterations at the hands of European colonists and modern ladino immigrants. Utilizing the methodologies of cultural geography, ethnohistory, and ethnogeography, the Pech, formerly known as the Paya, are scrutinized to illustrate the process by which indigenous peoples are reduced and incorporated into a developing national setting. Part One examines the scholarly record on the ethnohistory of the Pech and their neighbors to delimit their habitats and to document Pech incorporation into the …
The Impact Of Technological Change On The Economic Viability Of Individual Production Centers: The Case Of The 1840-1880 British Ocean-Going Iron And Steam Shipbuilding Industry., Daniel Stephen Allen
The Impact Of Technological Change On The Economic Viability Of Individual Production Centers: The Case Of The 1840-1880 British Ocean-Going Iron And Steam Shipbuilding Industry., Daniel Stephen Allen
LSU Historical Dissertations and Theses
This dissertation examines the relationship between technological change and spatial industrial restructuring through a case study of the 1840-1880 British ocean-going iron and steam shipbuilding industry. The study tests the hypothesis that a shipbuilding center's share of the national British shipbuilding market was associated with its ability to generate or rapidly adopt technological change. The study begins by establishing iron steamship technological changes introduced by British shipbuilders and the industry's attendant spatial restructuring It then develops two site-specific variables: industrial viability and innovative ability. Data for both variables are obtained from the Lloyds Register of British and Foreign Shipping. The …
Suburbanization Of Office Space: A Case Study Of Houston, Texas., Dmitry Vadimovich Mesyanzhinov
Suburbanization Of Office Space: A Case Study Of Houston, Texas., Dmitry Vadimovich Mesyanzhinov
LSU Historical Dissertations and Theses
Since the 1950s, the service sector of the U.S. economy has experienced remarkable growth. Significantly, new jobs in business and professional services and in similar information-processing occupations required new workplaces. Consequently, thousands of office complexes were built in American cities. Displaying a clean break with the past trend, the majority of the new office complexes were constructed in suburban locations, outside the CBDs of most major cities. The purpose of this research is to investigate the relationships between office complexes and urban labor markets/urban spatial structure. The scope of the empirical work is confined to office suburbanization in Houston, Texas …
An Analysis Of Population Dispersal And Concentration In The United States, 1790-1990: The Frontier, Long Waves, And The Manufacturing Connection., Samuel Mark Otterstrom
An Analysis Of Population Dispersal And Concentration In The United States, 1790-1990: The Frontier, Long Waves, And The Manufacturing Connection., Samuel Mark Otterstrom
LSU Historical Dissertations and Theses
The United States has undergone massive changes in its population geography since 1790. A major component of these population shifts has been the rapid movement of the frontier westward. This dispersal of population through migration from relatively high densities along the eastern seaboard to the sparsely populated west was followed by concentration across most of the country after the general "closure" of the frontier. The rates of settlement growth and population concentration trends were not steady, but cyclical in nature, and they varied among the different regions of the country. This variation leads to a comparison of these phenomena with …
The Myth Of Narcissus And The Narcissistic Structure., Joachim Conrad Hermann Vogeler
The Myth Of Narcissus And The Narcissistic Structure., Joachim Conrad Hermann Vogeler
LSU Historical Dissertations and Theses
Since Freud's article "On Narcissism," behavioral psychologists have predominantly viewed this phenomenon as a personality disorder. This dissertation, in contrast, provides a psychoanalytic, i.e., Lacanian reading of the myth of Narcissus as it is recorded in classical literature, and brings about an understanding of the myth's underlying structure. The four fundamental exigencies of the myth's structure include the incest prohibition which symbolically castrates the human subject, the incestuous desire as a result of this prohibition, the displacement of this desire for another imaginary object, and the obsessive quest of that image as the symptom. This structure--defined as narcissistic structure and …
Americans And German Youth In Nuremberg, 1945-1956: A Study In Politics And Culture., Harald Thomas Oskar Leder
Americans And German Youth In Nuremberg, 1945-1956: A Study In Politics And Culture., Harald Thomas Oskar Leder
LSU Historical Dissertations and Theses
While American policy makers needed three years after World War II to recognize the importance of re-educating German youth and to develop a consistent policy, a look at Nuremberg reveals that American representatives in the field started positive and constructive programs immediately after the war. American soldiers ignored non-fraternization, the Army became heavily involved in helping German communities survive, while the Youth Section of the Office of Military Government was the first to focus on persuasion instead of coercion in its re-education efforts. It designed long range programs to introduce young Germans to a democratic culture. Official American policy simply …
Postmodern Messiah: A Critical Ethnography Of Elvis Presley As A Site Of Performance., Daniel Weaver Heaton
Postmodern Messiah: A Critical Ethnography Of Elvis Presley As A Site Of Performance., Daniel Weaver Heaton
LSU Historical Dissertations and Theses
In this study I used a critical ethnographic approach to investigate Elvis as a site of performance where cultural identity, authority and representation are contextualized within the cultural practices of fans, people who love Elvis, and funs, people who do not love Elvis, but still elect to use Elvis as the basis for their cultural performances. I argued that fans and funs use performance as the agency of postmodern identity construction. I explored three performance events in which both fans and funs participated. Additionally, I examined the relationship of power and play between and within fan and fun culture. I …

A Palynological Study Of Swamp Sediments At The Poverty Point Archaeological Site, Northeastern Louisiana, Karen Thomas
A Palynological Study Of Swamp Sediments At The Poverty Point Archaeological Site, Northeastern Louisiana, Karen Thomas
LSU Historical Dissertations and Theses
The Poverty Point site, characterized by elaborate earthworks, was occupied from about 1500 B.C. to 500 B.C. (Webb 1982). The site was the central node for a large manufacturing network at the end of the late Archaic Period. Questions of subsistence and the demise of the culture remain unanswered. This thesis employs a palynological study of a swamp in the Poverty Point archaeological site (16WC5), northeastern Louisiana. Eight cores were taken from a swamp immediately adjacent to the mounds at the site. Loss-on-ignition was done for four cores. Two cores, cores PP5 and PP7 were used for pollen analysis; core …

Dna Sequences Of Alu Elements Indicate A Recent Replacement Of The Human Autosomal Genetic Complement, Alec Knight, Mark A. Batzer, Mark Stoneking, Hemant K. Tiwari, W. Douglas Scheer, Rene J. Herrera, Prescott L. Deininger
Faculty Publications
DNA sequences of neutral nuclear autosomal loci, compared across diverse human populations, provide a previously untapped perspective into the mode and tempo of the emergence of modern humans and a critical comparison with published clonally inherited mitochondrial DNA and Y chromosome measurements of human diversity. We obtained over 55 kilobases of sequence from three autosomal loci encompassing Alu repeats for representatives of diverse human populations as well as orthologous sequences for other hominoid species at one of these loci. Nucleotide diversity was exceedingly low. Most individuals and populations were identical. Only a single nucleotide difference distinguished presumed ancestral alleles from …

Black Women's Listening: An Ethnography Of Listening In A Southern Inner-City Adult Learning Center., Jennifer Ann Falls
Black Women's Listening: An Ethnography Of Listening In A Southern Inner-City Adult Learning Center., Jennifer Ann Falls
LSU Historical Dissertations and Theses
The research investigated the phenomenon of listening in the context of adult literacy education. The purpose of this study was to explore and describe listening from the points of view of African American women who were teachers and adult learners in a welfare reform program. Using ethnography as a research methodology, this two-year study explored listening as it occurred in the Writing Class, a classroom culture that was situated in a Southern, inner-city adult learning center (Spindler & Spindler, 1982). The study investigated women's assumptions about listening, their own listening behaviors, and the behaviors they expected of listeners. An aim …
Restructuring In Louisiana Schools., Sharon Lee Pol
Restructuring In Louisiana Schools., Sharon Lee Pol
LSU Historical Dissertations and Theses
This study employs both quantitative and qualitative techniques to study the restructuring processes at the district, school, and teacher levels. The quantitative procedures include surveys used to distinguish between teachers's perceptions of highly and moderately restructured schools. Qualitative research techniques included interviews, observations, and document analysis to describe the restructuring. A new instrument, the Attributes of School Restructuring Scale (ASRS), was developed to measure teachers' knowledge about restructuring efforts and their involvement in the restructuring projects. The final version of the ASRS, included 48-items spread across three subscales: Budget/Finance, Governance/Decision-Making, and Curriculum/Instruction. The quantitative results from the statewide study indicated …

The Ecological Origins And Consequences Of Cattle Ranching In Sixteenth-Century New Spain, Andrew Sluyter
The Ecological Origins And Consequences Of Cattle Ranching In Sixteenth-Century New Spain, Andrew Sluyter
Faculty Publications
Despite the dramatic landscape changes Mexico has undergone due to the introduction of cattle ranching by the Spaniards in the early sixteenth century, the ecological origins of that pastroecosystem have remained obscure. About 1521, Gregorio de Villalobos implanted an Andalusian-derived herding ecology in the Gulf Coast lowlands that involved seasonal movement of cattle between wetlands and hill lands. Land-grant records demonstrate that as the colonial economy expanded, the transhumant model proliferated and came into conflict with those native settlements that had survived the pandemics of the early sixteenth century. In circumventing viceregal laws meant to protect native cultures and ecologies, …
"It Is Leviathan": Family, Feminism, And American Drama., Janet Vanderpool Haedicke
"It Is Leviathan": Family, Feminism, And American Drama., Janet Vanderpool Haedicke
LSU Historical Dissertations and Theses
American drama has ever occupied a stepchild position in scholarship, its denigration rooted in the lure of domestic realism for even the most resistant of our playwrights. Maligned as solipsistic and regressive, this "leviathan" of mainstream American theatre putatively upholds through its content the unity of the mythologized family and through its form the closure of classical realism. Yet the legacy of this leviathan is an epistemological subversion and a transformative impulse. Those very plays which apotheosize American domestic realism ironically undermine its foundation in psychological causality, narrative linearity, transparent language, unmediated consciousness, and unified meaning. Destabilizing that objective reality …
Walker Percy's Return To The Feminine., John Patrick Zmirak Jr
Walker Percy's Return To The Feminine., John Patrick Zmirak Jr
LSU Historical Dissertations and Theses
What has been lacking in the corpus of interpretation of Walker Percy's work is a synthesis of approaches, a reading of the novels that unites the philosophical, psychological, theological, and linguistic insights that have accrued over three decades of criticism, and applies them to the vexing question of sexuality within his novels. In the present work, Percy's four central, non-satiric novels, The Moviegoer, The Last Gentleman, Lancelot and The Second Coming, are analyzed in the light of the Christian allegorical tradition, which employs sexual categories to explicate the meta-physical order, and to inform sexuality with meaning. In each of Percy's …
Border Crossers And Coyotes: A Reception Study Of Latin American And Latina/O Literatures., Delia Maria Poey
Border Crossers And Coyotes: A Reception Study Of Latin American And Latina/O Literatures., Delia Maria Poey
LSU Historical Dissertations and Theses
Since the 1970s, there has been an ongoing debate within the humanities regarding the canon and curricular reform. Moving beyond questions of advocacy and the dichotomy of center and periphery (without diminishing the necessity of these), Border Crossers and Coyotes: A Reception Study of Latin American and Latina/o Literatures surveys the various ways which marginalized texts enter U.S. academic discourse as well as analyzing the conflicts inherent in these border crossings. The study proposes the position of the coyote, a person who transports undocumented workers across the U.S./Mexico border for profit, as analogous to that of the critic/teacher. Employing a …
An-Archy And Justice: An Introduction To Emmanuel Levinas's Political Thought., William Paul Simmons
An-Archy And Justice: An Introduction To Emmanuel Levinas's Political Thought., William Paul Simmons
LSU Historical Dissertations and Theses
Emmanuel Levinas's political thought is best understood as a tension between an-archy and justice. Levinas claims that the aim of philosophy has most often been a search for an arche, or a neuter term that accounts for all of reality. Levinas argues that the reduction of reality to an arche obliterates all transcendence and subordinates man to a totality. Against the predominance of totality in the Western tradition, Levinas proposes a philosophy of transcendence. This transcendence is not found in the direct relationship with God, but in the face of the other person, the Other. Since the face of the …
Honduras' Transisthmian Corridor: An Historical Geography Of Roadbuilding In Colonial Central America., Scott Arlen Brady
Honduras' Transisthmian Corridor: An Historical Geography Of Roadbuilding In Colonial Central America., Scott Arlen Brady
LSU Historical Dissertations and Theses
Historical route geographers consider the factors that influenced past roadbuilding, and the changes that result from roadbuilding. The earliest Spanish colonial officials in Central America initiated roadbuilding projects that were sensitive to physical and cultural factors. Officials had to consider the region's aboriginal routes, Spain's trade flows, the isthmus' topography, and the region's population distribution. The roads the Spaniards opened four centuries ago guided early settlement. In some cases, these early roads persist in the region's route network. During the 16th-century Spaniards sought to establish transisthmian roadways that would link Spain's Atlantic and Pacific maritime networks. Partial fluvial routes across …
