Reference Price Effects: The Role Of Multiple Internal Reference Prices And Semantic Cues., Balaji Chandrasekaran Krishnan

LSU Historical Dissertations and Theses

The purpose of this dissertation is two fold. The first objective is to assess the effect of price promotion on consumers' evaluation of the value of the deal independent of the specific IRP used by consumers. Towards this end, a subjective measure called "perceived fairness of the offer price" is introduced in a model hypothesizing relations among transaction utility, acquisition utility, and perceived value of the deal. The proposed model was compared to an existing model designed to predict and explain perceived value of the deal using a survey-based methodology, in the first study. Results indicate that the proposed model …

Considering Outcomes Beyond Achievement: Student Participation As An Indicator Of High School Performance., Susan Elizabeth Kochan-Teddlie

LSU Historical Dissertations and Theses

This dissertation is the product of a three-phase exploratory study that utilized both quantitative and qualitative methods in order to develop and test a composite indicator of high school performance that measures the degree to which high schools strike a balance between the press for academic excellence and the need to sustain all students--even the most marginal--on to high school completion. In Phase I, undaunted and relative performance indicators (UPIs and RPIs) of student achievement and participation were calculated for a statewide sample of 308 schools whose grade configurations included grades 9-12. The achievement scores were composites of student performance …

Development Of A New Methodology For Particle Transport Calculations Utilizing Pointwise-Continuous Nuclear Data., Mehdi Asgari

LSU Historical Dissertations and Theses

The purpose of this study is to develop a new method to compute a continuous-energy representation of the neutron flux spectrum using the one-dimensional discrete ordinates method. The technique provides a rigorous calculational tool for applications that require a detailed description of the fine-structure variation in the space-dependent neutron energy spectrum over some energy ranges. This technique uses the combination of multigroup (MG) and rigorous pointwise (PW) solutions to the steady state Boltzmann transport equation in the calculations. Also utilized in this methodology are two new methods called "sub-moment" expansion and "cumulative integral" operator to accurately evaluate the Legendre moments …

Directed Search In K-System Reconstruction., Christopher W. Branton

LSU Historical Dissertations and Theses

K-systems analysis is a factor analysis technique created through the generalization of key reconstructability analysis definitions and algorithms. The method is applied to functions on systems of discrete variables to discover a set of factors which can explain the bulk of the function's variation from the mean. K-systems analysis uses principles of information theory to reveal interactions which are often masked by the assumptions implicit in traditional methods. The method has been used successfully to analyze systems in several disciplines. Despite the success of k-systems analysis, obstacles to the creation of a mature methodology still exist. Some issues and open …

The dynamics of oxidation of aluminum nanoclusters is studied with a MD scheme that can simultaneously treat metallic and oxide systems. Dynamic charge transfer between anions and cations which gives rise to a compute-intensive Coulomb interaction, is treated by the O(N) Fast Multipole Method. Structural and dynamical correlations and local stresses reveal significant charge transfer and stress variations which cause rapid …

Subterranean Echoes: Curriculum Theory As Cultural Studies., Toby Allan Daspit

LSU Historical Dissertations and Theses

Cultural studies has emerged in recent decades as a popular realm of academic inquiry (During, 1993). Giroux (1994), while noting the field's increased acceptance, ponders why cultural studies has yet to permeate critical analyses of education and simultaneously questions cultural studies' reticence in considering schools as an important site of cultural production. Edgerton (1996) concurs with Giroux and notes that cultural studies' use in colleges of education is extremely rare. The realm of popular culture, one of the central foci of cultural studies, has especially been marginalized in academic discourses. My project is to explore the implications of curriculum theory …

Thermomechanical Characterization Of Heat-Activated Coupling For Advanced Composite Piping Systems., Patrick Fitzgerald Mensah

LSU Historical Dissertations and Theses

A new technology for joining advanced composite piping systems, based on heat-activated coupling (HAC) of a thermosetting pre-impregnated (prepreg) fiber reinforced material has been advanced. The successful design of a heat-activated coupled joint depends on achieving the following requirements: (1) uniformly cured prepreg bonded to the surfaces of coupled pipe; and (2) minimal residual thermal stress as a result of the curing process. In order to address the above concerns, thermal characterization of the uncured and cured prepreg used was undertaken in order to establish prerequisite chemical kinetics parameters and material property data required for the curing process models and …

Assessing The Reuse Potential Of Objects., Maria Lorna Reyes

LSU Historical Dissertations and Theses

In this research, we investigate whether reusable classes can be characterized by object-oriented (OO) software metrics. Three class-level reuse measures for the OO paradigm are defined: inheritance-based reuse, inter-application reuse by extension, and inter-application reuse as a server. Using data from a software company, we collected metrics on Smalltalk classes. Among the 20 metrics collected are cyclomatic complexity, Lorenz complexity, lines of code, class coupling, reuse ratio, specialization ratio and number of direct subclasses. We used stepwise regression to derive prediction models incorporating the 20 metrics as the independent variables and the reuse measures, applied separately, as the dependent variable. …

Pseudo Power Signatures For Nonstationary Signal Analysis And Classification., Vidya Venkatachalam

LSU Historical Dissertations and Theses

This research focuses on the analysis and classification of multicomponent non-stationary signals of arbitrary duration. The proposed classification approach has potential applications in areas like moving target detection, object recognition, oil exploration, and speech processing. The wavelet transform is used as the basis for the analysis. The classification technique is based on novel scale energy density functions, called pseudo power signatures , which are independent of signal length, and which can be used to characterize the time-scale energy distribution of the signal. These signatures allow for fast classification of signals regardless of their length. Two approaches to determine pseudo power …

Stress And Strength Of Laminated Composite Containing A Circular Hole., Yi Zhao

LSU Historical Dissertations and Theses

This dissertation is to study the stress and strength of a finite laminated plate containing a circular hole subjected to tension. Efforts were made in three aspects: theoretical modeling, computer simulation using finite element method, and experimental evaluation using unidirectional and crossply Scotchply laminates. The stress concentration factor, normal stress distribution and tensile strength of laminates with various hole sizes and gage lengths were investigated. Theoretically, two models were proposed to describe the normal stress distribution of a laminate with finite width and finite length. By defining a width correction function and a size correction function, the normal stress in …

Open Systems, Free Markets, And Regulation Of Internet Commerce, Jane Kaufman Winn

Articles

Can commercial transactions conducted over the Internet be regulated by existing commercial law doctrines? Many promoters of Internet commerce argue that business done over open computer networks such as the Internet will require a new regulatory framework In fact, many issues raised by Internet commerce have already been considered at length in the context of electronic commerce conducted over closed computer networks, such as those used in financial markets.

One of the most hotly debated issues regarding the regulation of Internet commerce is the question of what would be the online equivalent of a signature. Some have argued that, because …

Gn.3(C) Is Prime If N Is Odd, John Ferdinands

University Faculty Publications and Creative Works

A finite CW complex X is said to be prime if for every Hurewicz fibration F → E → B with E homotopy equivalent to X, and B and F homotopically equivalent to finite CW complexes, either B or F is contractible. We show that the 3-plane complex Grassmannian Gn.3(C) is prime if n is odd.

Modelling The Prevalence Of Down Syndrome With Applications Of Markov Chain Monte Carlo Methods, Isabelle Cella Bray

School of Engineering, Computing and Mathematics Theses

This thesis was motivated by applications in the epidemiology of Down syndrome and prenatal screening for Down syndrome. Methodological problems arising in these applications include under-ascertainment of cases in livebirth studies, double-sampled data with missing observations and coarsening of data. These issues are considered from a classical perspective using maximum likelihood and from a Bayesian viewpoint employing Markov chain Monte Carlo (MCMC) techniques. Livebirth prevalence studies published in the literature used a variety of data collection methods and many are of uncertain completeness. In two of the nine studies an estimate of the level of under-reporting is available. We present …

Fluid Inertia And End Effects In Rheometer Flows, Jason Hughes

School of Engineering, Computing and Mathematics Theses

This thesis is concerned with the characterisation of the flow behaviour of inelastic and viscoelastic fluids in steady shear and oscillatory shear flows on commercially available rheometers. The first part of this thesis is concerned with a linear viscoelastic theory to describe the oscillatory shear flow behaviour of fluids on a Weissenberg rheogoniometer. A fluid inertia perturbation analysis is used to produce analytical formulae for correcting complex viscosity data for first and second order fluid inertia effects. In order to validate the perturbation theory we perform a simulation of the oscillatory shear flow behaviour of Newtonian and single element Maxwell …

Creating A Canonical Scientific And Technical Information Classification System For Ncstrl+, Melissa E. Tiffany, Michael L. Nelson

Computer Science Faculty Publications

The purpose of this paper is to describe the new subject classification system for the NCSTRL+ project. NCSTRL+ is a canonical digital library (DL) based on the Networked Computer Science Technical Report Library (NCSTRL). The current NCSTRL+ classification system uses the NASA Scientific and Technical (STI) subject classifications, which has a bias towards the aerospace, aeronautics, and engineering disciplines. Examination of other scientific and technical information classification systems showed similar discipline-centric weaknesses. Traditional, library-oriented classification systems represented all disciplines, but were too generalized to serve the needs of a scientific and technically oriented digital library. Lack of a suitable existing …

Model Results Of Flow Instabilities In The Tropical Pacific Ocean, Kathleen A. Donohue, Mark Wimbush

Graduate School of Oceanography Faculty Publications

A two‐and‐a‐half‐layer model of the tropical Pacific Ocean is used to investigate the energy source for the intraseasonal dynamic‐height variability observed near 6°N. A simulation of equatorial circulation is produced by forcing the model with mean‐monthly wind‐stress climatology. Two westward‐propagating waves appear in the upper layer in the central and eastern portion of the model basin. These two waves are distinguished by period and meridional structure. An off‐equatorial wave with period of 30 days and wavelength of 1100 km has a meridional sea‐level maximum near 6°N similar to that of the 30–50 day intraseasonal wave observed in the ocean. The …

Effects Of Submergence On Embryonic Survival And Developmental Rate Of The Florida Applesnail, Pomacea Paludosa: Implications For Egg Predation And Marsh Management, Richard L. Turner

Ocean Engineering and Marine Sciences Faculty Publications

Aerial deposition of egg clutches by the aquatic Florida applesnail is believed to have evolved in response to aquatic egg predators. Adaptation to aerial conditions might, however, have rendered embryos intolerant of submergence, a potential occurrence in natural and managed marshes, rivers, and lakes. In this study, eggs were submerged in water for various durations in the laboratory to assess their ability to survive flooding; and clutches of known ages were submerged for several days in the field to determine if aquatic predators might decrease survival below levels expected to occur due to flooding alone. Submergence of clutches slowed embryonic …
