Reverse Engineering Low-Level Design Patterns From Object-Oriented Code., Chandra Shrivastava Jan 1996

Reverse Engineering Low-Level Design Patterns From Object-Oriented Code., Chandra Shrivastava

LSU Historical Dissertations and Theses

The purpose of this research is to develop and automatically extract an abstract representation model of object-oriented (abbreviated as OO) software systems that captures the structure of the system and code dependencies, in order to aid maintenance. The research resulted in the development of two abstract representation models--the low-level design pattern (LLDP) abstract model and the low-level software architecture (LLSA) abstract model. The LLDP model is at a higher level of abstraction than the LLSA model. The LLSA model acts as an intermediate representation between the LLDP model and an OO software system. The design of the LLSA and LLDP …

Characterization Of Ionizing Radiation Sensitive (Irs) Mutants Of Deinococcus Radiodurans R1., Kumaraswamy S. Udupa Jan 1996

Characterization Of Ionizing Radiation Sensitive (Irs) Mutants Of Deinococcus Radiodurans R1., Kumaraswamy S. Udupa

LSU Historical Dissertations and Theses

Deinococcus radiodurans is extremely resistant to ionizing radiation and can withstand 5 kGy $\gamma$ radiation without loss of viability or evidence of mutation. Available evidence argues that an efficient DNA repair mechanism is responsible for the resistance these organisms possess to ionizing radiation. The enzymes which coordinate DNA repair in D. radiodurans are poorly characterized. Two new loci have been detected in D. radiodurans, namely, irrB and irrI which provide resistance. Mutational inactivation of either locus resulted in a partial loss of resistance to ionizing radiation. The extent of sensitivity was locus specific and differentially affected by inactivation of the …

Scale, Resolution And Resampling: Representation And Analysis Of Remotely Sensed Landscapes Across Scale In Geographic Information Systems., Stephanie Jean Weigel Jan 1996

Scale, Resolution And Resampling: Representation And Analysis Of Remotely Sensed Landscapes Across Scale In Geographic Information Systems., Stephanie Jean Weigel

LSU Historical Dissertations and Theses

Earth system scientists are increasingly using the technologies of Geographic Information Systems (GIS) and Remote Sensing (RS) in their analyses of earth system processes and patterns. These investigations take place over a wide range of scales, from the local to the global. Global change researchers focus on both the physical and human dimensions of changes in the earth's landscapes, which occur across a range of scales and may be scale dependent. The way in which landscapes are represented in GIS and RS, using specific spatial data models and data spatial resolutions, affects the subsequent analyses that can be performed. Optimally …

The Effects Of Analytic Reading Skills On Sixth Graders' Ability To Solve Mathematical Story Problems., Linda Hale Eilers Jan 1996

The Effects Of Analytic Reading Skills On Sixth Graders' Ability To Solve Mathematical Story Problems., Linda Hale Eilers

LSU Historical Dissertations and Theses

The purpose of the present study was to determine the effects of two levels of instructional treatment on sixth graders' ability to solve mathematical story problems. The two levels of instructional treatment were instruction in the use of graphic organizers in conjunction with specific analytic reading skills and instruction in specific analytic reading instruction alone. These were compared to the absence of either treatment. The steady decline in students' scores on measures of ability to read and solve story problems over the past decade prompted research in three sixth-grade public school classes in northeast Louisiana. The study employed an experimental/control, …

Performance, Cultural Identity, And Feminist Practice In The Oral History Of An African-American Domestic Worker., Elondust Patrick Johnson Jan 1996

Performance, Cultural Identity, And Feminist Practice In The Oral History Of An African-American Domestic Worker., Elondust Patrick Johnson

LSU Historical Dissertations and Theses

This study analyzes the personal narrative of Mary Rhyne, an elderly African American domestic worker. The study describes the ethnographic process of collecting, transcribing and interpreting the informant's oral history. Interpretive and theoretical perspectives concerned with African American culture, domestic labor, and feminist practice are used to analyze the narrative. Further, the ethnographic process, the informant's oral "telling," and the events that she recalls and recounts are viewed as, and in terms of, performance. Performance foregrounds the collaborative and "fictional" aspects of the ethnographer-informant relationship. It directs attention toward the "performance event" as a site and situation where the teller …

Reflection On Teaching: An Ethnographic Study Of Preservice Teachers' Beliefs And Practices., Thomasine Haskins Mencer Jan 1996

Reflection On Teaching: An Ethnographic Study Of Preservice Teachers' Beliefs And Practices., Thomasine Haskins Mencer

LSU Historical Dissertations and Theses

The purpose of this study was to explore the relationship between preservice teachers' expressed beliefs, their practices, and how they described the two. Particular emphasis was given to factors that influenced the preservice teachers' expectations of students. The preservice teachers were in the graduate year of a five year teacher education program that embraced reflective practice. In many ways, the two preservice teachers conformed to the mold of the typical American teacher in that they were middle class, Anglo Saxon, females who were high achievers from small towns. However, the pair differed in their experiences with diversity. The preservice teachers' …

The Role Of Seed Banks, Disturbance, And Sea Level Rise In Determining The Plant Community Structure Of Oligohaline Coastal Marshes., Andrew Hamilton Baldwin Jan 1996

The Role Of Seed Banks, Disturbance, And Sea Level Rise In Determining The Plant Community Structure Of Oligohaline Coastal Marshes., Andrew Hamilton Baldwin

LSU Historical Dissertations and Theses

Coastal wetlands worldwide are threatened by sea level rise, which is expected to affect the growth and survival of wetland vegetation by increasing water level and salinity. While the effects of salinity and inundation on adult vegetation of oligohaline marshes have been widely studied, the species composition of the seed bank and its response to elevated salinity and water level have not been examined. Additionally, the role of disturbances of different intensities in structuring marsh plant communities and possible interactions between disturbance and rising sea level have received little attention. Disturbances in coastal marshes include nonlethal disturbances such as fire …

The Relationship Of Hemolymph Sugar, Juvenile Hormone And Biogenic Amines To The Three Behavioral States Of Mature Honey Bees., Janko Bozic Jan 1996

The Relationship Of Hemolymph Sugar, Juvenile Hormone And Biogenic Amines To The Three Behavioral States Of Mature Honey Bees., Janko Bozic

LSU Historical Dissertations and Theses

Differences in sugar titers, JH synthesis rate and biogenic amine metabolism correlated with three distinct activity groups or mature bees: resting bees, followers and dancers. Dancers had lower trehalose titers than followers or resting bees. In absconding bees trehalose titers were even lower, due to greatly elevated locomotor activity. The collecting and transferring of food by dancers and followers resulted in a higher glucose titer than in resting bees. Followers had a higher-JH synthesis rate than dancers, suggesting that JH could be an internal motivational stimulus to recruit followers to forage. Dancers and followers collect and transfer food and therefore …

The Phytochrome Gene Family In Grasses (Poaceae): A Phylogeny And Evidence That Grasses Have A Subset Of The Loci Found In Dicot Angiosperms, S. Mathews, Robert A. Sharrock Jan 1996

The Phytochrome Gene Family In Grasses (Poaceae): A Phylogeny And Evidence That Grasses Have A Subset Of The Loci Found In Dicot Angiosperms, S. Mathews, Robert A. Sharrock

Faculty Publications

The phytochrome nuclear gene family encodes photoreceptor proteins that mediate developmental responses to red and far red light throughout the life of the plant. From studies of the dicot flowering plant Arabidopsis, the family has been modeled as comprising five loci, PHYA-PHYE. However, it has been shown recently that the Arabidopsis model may not completely represent some flowering plant groups because additional PHY loci related to PHYA and PHYB of Arabidopsis apparently have evolved independently several times in dicots, and monocot flowering plants may lack orthologs of PHYD and PHYE of Arabidopsis. Nonetheless, the phytochrome nucleotide data were informative in …

Improved Method For Selecting Kick Tolerance During Deepwater Drilling Operations., Shiniti Ohara Jan 1996

Improved Method For Selecting Kick Tolerance During Deepwater Drilling Operations., Shiniti Ohara

LSU Historical Dissertations and Theses

One of the most critical aspects in the design of oil and gas wells is the selection of the depths at which steel casing is set. As the length of open borehole increases, the risk of formation fracturing during drilling operations increases. Formation fracture often leads to an underground blowout that can be very expensive to control. Because of the special problems involved in drilling deepwater well, accurately measuring the risk of formation fracture is essential. A calculated parameter called "kick tolerance" is often used to measure this risk. In this study, improved computer software specifically designed for computing kick …

Reconstructing Educational Experience: A Postmodern Perspective., Jeanne Edwards Robertson Jan 1996

Reconstructing Educational Experience: A Postmodern Perspective., Jeanne Edwards Robertson

LSU Historical Dissertations and Theses

Education in America today is dominated by the either/or thinking of modernism. This mode of thought is connected to both the concepts and methods of modern, mechanistic, Newtonian science. However, the attendant reductionistic methodology has been elevated beyond its realm of efficacy to the level of a world view, a metaphysical level. This is demonstrated by the omnipresence of the machine metaphor in all areas of human endeavor. The machine is the root metaphor of modernism. John Dewey speaks of a "new order of conceptions" necessary for significant change. These new order concepts are manifest in the new or postmodern …

Honduras' Transisthmian Corridor: An Historical Geography Of Roadbuilding In Colonial Central America., Scott Arlen Brady Jan 1996

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 …

Automatic Data And Computation Mapping For Distributed-Memory Machines., Isidoro Couvertier-Reyes Jan 1996

Automatic Data And Computation Mapping For Distributed-Memory Machines., Isidoro Couvertier-Reyes

LSU Historical Dissertations and Theses

Distributed memory parallel computers offer enormous computation power, scalability and flexibility. However, these machines are difficult to program and this limits their widespread use. An important characteristic of these machines is the difference in the access time for data in local versus non-local memory; non-local memory accesses are much slower than local memory accesses. This is also a characteristic of shared memory machines but to a less degree. Therefore it is essential that as far as possible, the data that needs to be accessed by a processor during the execution of the computation assigned to it reside in its local …

Importance Of A Siderophore In The Pathogenesis And Virulence Of Photobacterium Damsela Subsp. Piscicida In Hybrid Striped Bass (Morone Saxatili X Morone Chrysops)., John Phillip Hawke

LSU Historical Dissertations and Theses

Photobacterium damsela subsp. piscicida, formerly Pasteurella piscicida, is an important new pathogen of hybrid striped bass cultured in brackish water on Louisiana mariculture farms. Louisiana isolates compared with strains of P. damsela subsp. piscicida from Greece, Japan, Israel and Chesapeake Bay, USA and were found to be identical in biochemical phenotype and enzymic activity. Small plasmids of 8 and 5 kb were unique to Louisiana strains. Sequential daily bacteriology and histopathology on hybrid striped bass experimentally infected by immersion revealed that following high doses (13,000 CFU/ml) the gills and spleen are colonized first as early as 24 hours PI, followed …

Amorphization And Fracture In Silicon Selenium(2) Nanowires: Molecular-Dynamics Simulations On Parallel Computer Architectures., Wei Li Jan 1996

Amorphization And Fracture In Silicon Selenium(2) Nanowires: Molecular-Dynamics Simulations On Parallel Computer Architectures., Wei Li

LSU Historical Dissertations and Theses

The primary goal of this dissertation is to investigate the structural and mechanical properties and dynamical fracture in SiSe$\sb2$ nanowires using the molecular-dynamics (MD) simulation technique. The present work is the first study of SiSe$\sb2$ nanowires. Large-scale simulations reported in this thesis are carried out with parallel multiresolution schemes for the long-range Coulomb and the three-body covalent potentials. The multiresolution scheme reduces the computational complexity from O(N$\sp2$) to O(N). Using an effective interatomic potential containing both 2- and 3-body interactions, MD simulations are performed for SiSe$\sb2$ nanowires composed of finite (1-64) number of chains. Under small uniaxial strain, the nanowires …

Discontinuous Technological Change And Institutional Legitimacy: A Morphological Perspective., Robert Nicholas Mcgrath Jan 1996

Discontinuous Technological Change And Institutional Legitimacy: A Morphological Perspective., Robert Nicholas Mcgrath

LSU Historical Dissertations and Theses

Technological innovation is an important consideration to many strategic managers and thus is important to research in Strategic Management. Deepening the field's understanding of what technology is and how it works can be facilitated by participating in a growing dialogue between the Strategic Management and Management of Technology communities. This dissertation considers elements of both fields and examines the premise that at the industry level, incumbents act to manipulate the "share of mind" or "cognitive legitimacy" of the performance and cost/price characteristics of product-technology innovations that, in aggregate, portend to either enhance or destroy prevailing industry competences. A forecasting technique …

Image Analysis Quantification Of Decondensation Of Bovine Spermatozoa And Pcr Amplification Of A Y Chromosome Specific Sequence., Hilde Christina Steinholt Jan 1996

Image Analysis Quantification Of Decondensation Of Bovine Spermatozoa And Pcr Amplification Of A Y Chromosome Specific Sequence., Hilde Christina Steinholt

LSU Historical Dissertations and Theses

The first objective of this research was to develop a decondensation treatment for bovine spermatozoal DNA that worked consistently across bulls and breeds. The second objective was to use the decondensed DNA for polymerase chain reaction analysis of levels of Y-bearing spermatozoa in different ejaculates and in sex sorted spermatozoa. Decondensation of spermatozoa with dithiothreitol and potassium hydroxide was compatible with in vitro amplification and did not inhibit amplification. The polymerase chain reaction and image analysis were used to differentiate between proportions of Y spermatozoa by measuring fluorescent intensities of electrophoresed, polymerase chain reaction-amplified DNA. There were differences in intensities …

Children's Relative Influence In Purchase Decision-Making: A Multi-Theoretical Approach., Laura Ann Willis Williams Jan 1996

Children's Relative Influence In Purchase Decision-Making: A Multi-Theoretical Approach., Laura Ann Willis Williams

LSU Historical Dissertations and Theses

Sociological changes in the American family have positioned children to wield greater power in family purchase decisions. Although past descriptive research has confirmed that children are an important source of power in the household, this research has not explored the conceptual justification for the observed patterns of children's relative influence. To fill this gap in the family decision-making literature, this research develops a multi-theoretical conceptual model to explain children's relative influence in a purchase context. Social power theory, resource theory, social exchange theory, and social comparison theory were the conceptual frameworks for this research. Six studies were conducted, including a …

Robust Sensor Fusion Algorithms: Calibration And Cost Minimization., Richard Ree Brooks Jan 1996

Robust Sensor Fusion Algorithms: Calibration And Cost Minimization., Richard Ree Brooks

LSU Historical Dissertations and Theses

A system reacting to its environment requires sensor input to model the environment. Unfortunately, sensors are electromechanical devices subject to physical limitations. It is challenging for a system to robustly evaluate sensor data which is of questionable accuracy and dependability. Sensor fusion addresses this problem by taking inputs from several sensors and merging the individual sensor readings into a single logical reading. The use of heterogeneous physical sensors allows a logical sensor to be less sensitive to the limitations of any single sensor technology, and the use of multiple identical sensors allows the system to tolerate failures of some of …

The Amazon Myth In Western Literature., Bruce Robert Magee Jan 1996

The Amazon Myth In Western Literature., Bruce Robert Magee

LSU Historical Dissertations and Theses

This dissertation identifies and evaluates the ways in which the Amazon myth has functioned. The Amazon myth functions within broader discourses about the Orient, Africa, and women. It has implications for the ways we define "self" and "other." Because they are often represented as a threat to the border from long ago and/or far away, Amazons can serve both as an excuse for fortifying the center against the margin, and as a way of projecting fantasies into the void. The Amazon myth has incited men to action as they have searched for adventure and Amazons abroad. Intended in part as …

The Effects Of Industry Deregulation On The Stock Market Responses To Earnings Announcements., Wah Poon Jan 1996

The Effects Of Industry Deregulation On The Stock Market Responses To Earnings Announcements., Wah Poon

LSU Historical Dissertations and Theses

Many sectors of the United States economy have experienced deregulation during the 1970s and 1980s. This study examines how deregulation affects the informativeness of accounting earnings of firms in deregulation industries. In this study, the informativeness of accounting earnings is measured by the earnings response coefficient (ERC, the slope coefficient in the regression of abnormal stock returns on unexpected accounting earnings). The effects of deregulation on ERCs are examined by (1) comparing ERCs before deregulation to those after deregulation to determine the changes in the magnitude of ERCs due to deregulation, (2) investigating the time series of ERCs after deregulation …
