An Inquiry Into The Impact Of Teacher Variances Within The Implementation Of The Success For All Reading Program In Two School Districts., Karen Parker Guillot
An Inquiry Into The Impact Of Teacher Variances Within The Implementation Of The Success For All Reading Program In Two School Districts., Karen Parker Guillot
LSU Historical Dissertations and Theses
Elementary school students walk single file to their respective classrooms where literacy should miraculously transpire. For literacy to occur, some schools adopt reading programs provided by their local district or state, while others utilize externally developed program designs. This multiple-case qualitative inquiry examined the externally developed program, Success for All, a program designed to benefit high poverty schools, founded by Robert Slavin and Nancy Madden as well as their cohorts at Johns Hopkins University. This research study examined the variances among seven teachers implementing the SFA reading program, "Reading Wings," in three schools in two school districts in Louisiana. It …
The Effects Of The Laboratory On College Students' Understanding Of Evolution: Implications For Conceptual Change., Lorna Benita Holtman
The Effects Of The Laboratory On College Students' Understanding Of Evolution: Implications For Conceptual Change., Lorna Benita Holtman
LSU Historical Dissertations and Theses
This study investigated eighty junior and senior college students' understanding of evolutionary biology concepts in lecture-only and lecture-laboratory settings. The evolution lab stressed the processes of evolution, and involved simulations, experiments, discussions, report writing, and reading. Test scores do not reveal everything about the actual process of learning in the laboratory. This study examined conceptual change patterns over a period of one semester using in-depth interviews with eight participants. The study revealed that the lecture-laboratory group performed better than the lecture-only group on certain shared items on the objective examination. The interview participants showed various patterns of conceptual change; that …
Simulations And Algorithms On Reconfigurable Meshes With Pipelined Optical Buses., Anu Goel Bourgeois
Simulations And Algorithms On Reconfigurable Meshes With Pipelined Optical Buses., Anu Goel Bourgeois
LSU Historical Dissertations and Theses
Recently, many models using reconfigurable optically pipelined buses have been proposed in the literature. A system with an optically pipelined bus uses optical waveguides, with unidirectional propagation and predictable delays, instead of electrical buses to transfer information among processors. These two properties enable synchronized concurrent access to an optical bus in a pipelined fashion. Combined with the abilities of the bus structure to broadcast and multicast, this architecture suits many communication-intensive applications. We establish the equivalence of three such one-dimensional optical models, namely the LARPBS, LPB, and POB. This implies an automatic translation of algorithms (without loss of speed or …

The study used three different populations in addressing the specific objectives of the study. The first and primary population in the study was defined the head coaches, the second population was defined as all member institutions of the Southeastern Conference, and the third population consisted of the individual sports that are supported by each institution and recognized by the Southeastern Conference. The instrument used to collect the data in this study was …
Comparative Biology And Ecology Of The Formosan Subterranean Termite, Coptotermes Formosanus Shiraki (Isoptera: Rhinotermitidae) In Louisiana., Huixin Fei
LSU Historical Dissertations and Theses
A laboratory study was conducted to investigate the effects of sibship patterns and different origins of colonies on mate mortality and growth of incipient colonies in the subterranean termite, Coptotermes formosanus Shiraki. Primary reproductives from New Orleans in nonsibling pairs had significantly higher mortality than sibling pairs. The average egg production for sibling and nonsibling pairs showed no overall significance in the first oviposition period, however, the average number of larvae was consistently higher in nonsibling than in sibling-founded colonies from New Orleans. After two years, the average number of eggs or larvae present in nonsibling-founded colonies was significantly higher …
Narrative Structure And Characters In The Nanzi Stories Of Curacao: A Discourse Analysis., Joke Maaten Mondada
Narrative Structure And Characters In The Nanzi Stories Of Curacao: A Discourse Analysis., Joke Maaten Mondada
LSU Historical Dissertations and Theses
This dissertation develops a new approach to the analysis of narratives by combining the analysis of narrative structure and character analysis. Through the in-depth analysis of two stories of a collection of 32 Nanzi stories (from Curacao), which are spider/trickster stories in Papiamentu, I develop a method to analyze the structure of the Nanzi stories. My method is based on the determination of narrative division into (1) episodes, organized as macro-propositions under a macro-structure (Van Dijk 1982; 1992); (2) different sections (six), based on narrative and free clauses (Labov 1972); and, (3) major events (Barthes 1975; Chatman 1978). By applying …
The Effect Of Negative Events And Firm Responses On Brand Associations, Organizational Associations, And Brand Evaluations., Chris Patrick Pullig
The Effect Of Negative Events And Firm Responses On Brand Associations, Organizational Associations, And Brand Evaluations., Chris Patrick Pullig
LSU Historical Dissertations and Theses
This dissertation examines the impact of negative events and firm responses to such events on an associative network of brand knowledge; key consumer brand and organizational associations, risk perceptions, and brand response variables. To accomplish this objective the issue of how negative event information is integrated with an existing brand/organizational image was assessed within the framework of a consumer-brand relationship. Two between-subjects experiments were conducted using adult consumers as subjects. In Study One, negative events were found to affect associations linked to the brand and limit the brand's ability to fulfill the consumer-brand relationship. Two types of events were identified, …

Functional Microanatomy Of The Feather-Bearing Integument: Implications For The Evolution Of Birds And Avian Flight, Dominique G. Homberger, Kumudini N.D.E. Silva
Functional Microanatomy Of The Feather-Bearing Integument: Implications For The Evolution Of Birds And Avian Flight, Dominique G. Homberger, Kumudini N.D.E. Silva
Faculty Publications
A selective regime favoring a streamlining of body contours and surfaces is proposed as having been instrumental in driving the morphological and functional transformations of an unfeathered reptilian integument into a featherbearing avian one. This hypothesis is consistent with a new, structurally and functionally coherent analysis of the microanatomy of the avian feather-bearing integument as a complex, integrated organ system that includes an intricate, hydraulic skeleto-muscular apparatus of the feathers, a dermo-subcutaneous muscle system of the integument, and a subcutaneous hydraulic skeletal system formed by fat bodies. Key elements of the evidence supporting the new hypothesis are (1) the presence …

T cell immunity to lytic proteins of herpesviruses is important in host control of infection. We have characterized the cytotoxic T lymphocyte (CTL) response to 5 human herpesvirus 8 (HHV-8) homologues of lytic proteins in HHV-8-seropositive individuals. HLA class I-restricted, CD8+ CTL responses to ≥1 HHV-8 lytic protein were detected in all 14 HHV-8-seropositive study subjects tested, with or without human immunodeficiency virus type 1 (HIV-1) infection, but not in any of 5 HHV-8-seronegative individuals. Seven of these study subjects with both HHV-8 and HIV-1 infection had greater anti-CTL reactivity to glycoprotein H (open-reading frame 22) than did the 7 …

A multiplex amplification and detection platform for the diagnosis of Mycobacterium bovis and Brucella abortus infection simultaneously in bovine milk and nasal secretions was developed. This system (designated the bovine pathogen detection assay [BPDA]-PCR) consists of duplex amplification of species-specific targets (a region of the BCSP31K gene of B. abortus and a repeat-sequence region in the hsp65 gene of M. bovis, respectively). This is followed by a solid-phase probe capture hybridization of amplicons for detection. On the basis of spiking experiments with normal milk, the analytical sensitivity of the assay was 800 CFU equivalents/ml of milk for B. abortus and …
Multiple Bus Networks For Binary -Tree Algorithms., Hettihewage Prasanna Dharmasena
Multiple Bus Networks For Binary -Tree Algorithms., Hettihewage Prasanna Dharmasena
LSU Historical Dissertations and Theses
Multiple bus networks (MBN) connect processors via buses. This dissertation addresses issues related to running binary-tree algorithms on MBNs. These algorithms are of a fundamental nature, and reduce inputs at leaves of a binary tree to a result at the root. We study the relationships between running time, degree (maximum number of connections per processor) and loading (maximum number of connections per bus). We also investigate fault-tolerance, meshes enhanced with MBNs, and VLSI layouts for binary-tree MBNs. We prove that the loading of optimal-time, degree-2, binary-tree MBNs is non-constant. In establishing this result, we derive three loading lower bounds Wn …
Rights Of Passage: A Cross -Cultural Study Of Maroon Novels By Black Women., Randi Gray Kristensen
Rights Of Passage: A Cross -Cultural Study Of Maroon Novels By Black Women., Randi Gray Kristensen
LSU Historical Dissertations and Theses
This study investigates the use and implications of the trope of marronage, the African-American practice of self-emancipation to forge alternative New World communities, in selected novels by Black women writers of North America and the Anglophone and Francophone Caribbean. It draws on theories of liminality to posit a theory of liberatory practice that deconstructs hegemonic narratives, both personal and historical. Postmodern approaches are deferred in favor of locating these texts and their concerns as deriving from the epistemological consequences of modernity. Cross-cultural Black women's texts were chosen to illuminate the recognition of shared subjugations across national and linguistic borders, as …
Reengineering Of Legacy Systems To Distributed Environments., Miguel Angel Serrano-Vargas
Reengineering Of Legacy Systems To Distributed Environments., Miguel Angel Serrano-Vargas
LSU Historical Dissertations and Theses
The object-oriented paradigm and client/server and distributed technologies have become widely used in the last decade. There is an increasing interest to migrate and reengineer legacy systems to these new hardware technologies and software development paradigms. Software engineers who wish to reengineer such legacy systems face challenges, such as lack of documentation and programs that are difficult to comprehend. Middleware technologies such as CORBA and DCOM make the development of new distributed systems, as well as the migration of legacy systems to distributed platforms, more feasible. Distribution of a system consists of two parts: (1) subsystem decomposition and (2) allocation …
The Effects Of Comparative Advertising Format On Consumer Responses: The Moderating Effects Of Brand Image And Attribute Relevance., Mehmet Ismail Yagci
The Effects Of Comparative Advertising Format On Consumer Responses: The Moderating Effects Of Brand Image And Attribute Relevance., Mehmet Ismail Yagci
LSU Historical Dissertations and Theses
Comparative advertising has become a popular and powerful promotion tactic for companies competing in a highly competitive marketplace. While most research examined comparison advertisements, focusing on one brand being compared to a competitor brand, "within-brand comparison" advertising has been neglected. Within-brand comparison advertising compares the attributes of an extension brand with the attributes of an original or replaced brand. This dissertation examines the relative effectiveness of two forms of comparative advertising tactics, "within-brand comparison" versus "across-brand comparison". The moderating effects of "brand image" and "attribute relevance" and the mediating effect of "ad believability" are also assessed by an experiment. Based …
Effects Of Cobalt-60 Gamma Irradiation On The Malaysian Prawn Macrobrachium Rosenbergii., Nyanti Lee
Effects Of Cobalt-60 Gamma Irradiation On The Malaysian Prawn Macrobrachium Rosenbergii., Nyanti Lee
LSU Historical Dissertations and Theses
A major obstacle in culture of the Malaysian prawn, Macrobrachium rosenbergii, is the complex social structure whereby a few large males dominate the population and reduce production. The goal of this work was to induce reproductive sterility by use of gamma radiation as a means to increase production. Of the 62 publications related to the use of gamma radiation in aquatic species published between 1938 and 1996, 66% did not indicate performance of dosimetry (dosage verification). Samples were not rotated during irradiation in 98% of these studies, which introduces considerable variation in dose. A dosimetric study in this dissertation found …
Diversity And Spatial Analysis Of Passerine Birds In Relation To Habitat Characteristics Of Woods Along The Northern Coast Of The Gulf Of Mexico., Jose Luis Alcantara
Diversity And Spatial Analysis Of Passerine Birds In Relation To Habitat Characteristics Of Woods Along The Northern Coast Of The Gulf Of Mexico., Jose Luis Alcantara
LSU Historical Dissertations and Theses
I studied the ecological diversity and spatial patterns of passerine birds during the springs of 1993, 1994, and 1995 at 3 stopover sites on the Chenier Plains of Louisiana and Texas. A "control" stand with dense understory vegetation and a "reduced" stand with modified understory were at each site. Data were collected on the structure and composition of vegetation and on the abundance and location of birds. Species richness, dominance, and diversity indices were computed for both vegetation and birds. Patterns of floristic impoverishment, greater dominance, and greater plant species diversity were found at the "reduced" stands. "Control" vegetation did …

What Goes On In Cross -Language Encounters: The Tactics And Strategies Of Interactional Grammar., Stuart Lee Stewart
What Goes On In Cross -Language Encounters: The Tactics And Strategies Of Interactional Grammar., Stuart Lee Stewart
LSU Historical Dissertations and Theses
This investigation involves analysis of cross-language encounters (CLEs), spoken discourse between native speakers (NSs) and non-native speakers (NNSs) of Spanish involved in two types of interactions: simulated service encounters and free conversation. I use a multi-tiered framework comprised of: (1) Schiffrin's (1994) functionalist approach, (2) a model of interactional grammar adapted from Ochs, Schegloff and Thompson (1996), and (3) one of the principal assumptions from conversation analysis, which focuses on the organization of interaction, while maintaining that participants' behavior provides evidence for the units, patterns and rules that are a part of all spoken interaction. Tactics and strategies examined include …

Both variable and fixed costs associated with precision grading are estimated on a per hour of operation basis as well as costs per acre and per cubic yard of dirt moved.
Angle-Dependent Magnetothermal Conductivity In D-Wave Superconductors, I. Vekhter, P. J. Hirschfeld
Angle-Dependent Magnetothermal Conductivity In D-Wave Superconductors, I. Vekhter, P. J. Hirschfeld
Faculty Publications
We analyse the behavior of the thermal conductivity, κ(H), in the vortex state of a quasi-two-dimensional d-wave superconductor when both the heat current and the applied magnetic field are in the basal plane. At low temperature the effect of the field is accounted for in a semiclassical approximation, via a Doppler shift in the spectrum of the nodal quasiparticles. In that regime κ(H) exhibits twofold oscillations as a function of the angle between the direction of the field in the plane and the direction of the heat current, in agreement with experiment. © 2000 Elsevier Science B.V.

Faculty Publications
Population-based candidate gene association analyses are becoming increasingly popular as a result of a greater number of genes and gene polymorphisms having been identified for which some functional information is available. Because many biochemical and physiologic systems impact blood pressure regulation and hypertension susceptibility, many of these identified genes and polymorphisms are candidates for population-level association studies involving blood pressure levels or hypertension status. Recent studies have suggested that the α-adducin gene may harbor polymorphisms that influence blood pressure level. Therefore, we embarked on a study to test one such polymorphism in two large US samples: one from an urban …

Bill Clinton's Operational Code: Assessing Source Material Bias, Mark Schafer, Scott Crichlow
Faculty Publications
This paper considers Bill Clinton's operational code as reflected in prepared speeches and spontaneous remarks. Differences between the two types of verbal material, their respective differences over time, and their respective variation after key intervening political events were subjected to analysis of variance as well as descriptive analyses. The results suggest that measurements based on spontaneous comments are preferable, particularly in providing sensitive measures of personal predispositions.
Origin, Distribution, And Degradation Of Sedimentary Organic Matter In A Modern Tropical Deltaic System (Mahakam Delta, Borneo, Indonesia)., Martine Joelle Hardy
Origin, Distribution, And Degradation Of Sedimentary Organic Matter In A Modern Tropical Deltaic System (Mahakam Delta, Borneo, Indonesia)., Martine Joelle Hardy
LSU Historical Dissertations and Theses
The modern, tidally influenced Mahakam Delta progrades onto the eastern Borneo continental shelf. The processes controlling the occurrence and preservation of sedimentary organic matter in a tropical deltaic setting are unknown. Understanding these processes has direct application in explaining the unusual origin of oil and gas generated from terrestrial plant debris (rather than typically from algal remains) in many tropical Miocene basins. Water salinity and dissolved oxygen, and sediment pH, Eh, and TOC were measured. Organic matter was extracted by acid digestion from 200 surface sediment samples collected from the Mahakam River, the delta, and the continental shelf. Seventeen types …
A Class Of Stable, Globally Noniterative, Nonoverlapping Domain Decomposition Algorithms For The Simulation Of Parabolic Evolutionary Systems., Yu Zhuang
LSU Historical Dissertations and Theses
Parabolic systems are governed by time dependent partial differential equations. To obtain a high simulation quality that captures important features of a parabolic system requires solving the governing equation to an adequate accuracy, which necessitates a large sampling size in the spatial and temporal dimensions, and hence a large amount of simulation data and high computing cost. Domain decomposition is an effective method of divide-and-conquer paradigm that divides the problem domain into several subdomains, reducing the original problem into several smaller interdependent problems which can be solved in parallel. In this dissertation, we propose a class of stabilized explicit-implicit time …

Exact Relations For Effective Tensors Of Composites: Necessary Conditions And Sufficient Conditions, Yury Grabovsky, Graeme W. Milton, Daniel S. Sage
Faculty Publications
Typically the elastic and electrical properties of composite materials are strongly microstructure dependent. So it comes as a nice surprise to come across exact formulae for effective moduli that are universally valid no matter what the microstructure. Such exact formulae provide useful benchmarks for testing numerical and actual experimental data and for evaluating the merit of various approximation schemes. They can also be regarded as fundamental invariances existing in a given physical context. Classic examples include Hill's formulae for the effective bulk modulus of a two-phase mixture when the phases have equal shear moduli, Levin's formulae linking the effective thermal …
