The Contribution Of Social Simulation In The Advancement Of Marketing Issues And Challenges, Mario V. González Fuentes
The Contribution Of Social Simulation In The Advancement Of Marketing Issues And Challenges, Mario V. González Fuentes
School of Business Faculty Research
For some years now, marketers have been praising for a more holistic approach of a company’s marketing efforts across all areas. However, traditional models show serious limitations to address the complexities of managing all of a company’s touch points with a customer. Agent-based modeling (ABM) has opened the door to explore the unfolding behaviors and outputs of an increasingly connected and interactive marketplace. The contribution of this paper is twofold. On the one hand, it provides researchers with a state-of-the-art repository for this strand of research. This facilitates the identification of relevant gaps in the literature and future research avenues. …

Storytelling In Comics: Who, When, And Where In “Here”, Michael W. Hancock
Storytelling In Comics: Who, When, And Where In “Here”, Michael W. Hancock
Comics and Graphic Novels
Richard McGuire’s groundbreaking short comic “Here” (1989) revolutionized storytelling possibilities in comics. It may be used within a short story unit to demonstrate familiar elements of fiction, including setting, plot, and character. Moreover, its inventive use of panels within panels to juxtapose past, present, and future can serve as a model for students’ visual rendering of multiple points in time within a single location.
Impacts And Recovery Of The Deepwater Horizon Oil Spill On Vegetation Structure And Function Of Phragmites Australis, Chad Robert Judy
Impacts And Recovery Of The Deepwater Horizon Oil Spill On Vegetation Structure And Function Of Phragmites Australis, Chad Robert Judy
LSU Master's Theses
Abstract The aim of this study was to determine the impacts of the Deepwater Horizon (DWH) oil spill on the common reed Phragmites australis, and the processes controlling species effects and recovery, via a greenhouse mesocosm study. In the greenhouse DWH source oil, weathered approximately 40% by weight and emulsified, was applied to the aboveground shoots of P. australis growing in marsh sods to produce the following treatment-levels: (1) oil coverage of the lower 30% of shoot-height, (2) the lower 70% of shoot-height, (3) repeated oil coverage of the lower 70% of shoot-height, (4) 100% oil coverage of shoots, (5) …

The Effect Of Teaching Biology Concepts With Animations Compared To Static Cartoons On Content Retention, Rebecca Adams Polk
LSU Master's Theses
This study explores the effect of animations versus static cartoons on students’ content retention in a high school biology classroom. Students were pre-tested prior to the introduction of content in three units of study: cellular transport, protein synthesis, and mitosis. After instruction on the topic via PowerPoint presentations, students were randomly assigned to either the test group or experimental group for each unit. The control group was removed from the room and given a series of static cartoons with captions to view. The experimental group viewed an animation on the topic, accompanied by teacher narration, which consisted of the captions …
The Feasibility Of Using Vanadium And Nickel To Track Oil Spills In Coastal Environments, Sean Patrick Kenny
The Feasibility Of Using Vanadium And Nickel To Track Oil Spills In Coastal Environments, Sean Patrick Kenny
LSU Master's Theses
Crude oil has been increasing in world demand over the past century. It is known that oil is resistant to weathering processes and if spilled, can cause serious environmental damage to an area, on land or sea. A complementary approach to current methods of tracking oil and identifying spill-impacted sediments may be to measure trace metals associated with crude oil. Trace metals, such a vanadium (V) and nickel (Ni) are known to be elevated in concentration in some oil sources, but little work has been done on this topic. This research explored less expensive and time-consuming methods to track or …
Temporal And Spatial Variations In The Subsurface Salinity Of Lake Charles, Louisiana : An Investigation Of Saline Sources, Alexandria Suding
Temporal And Spatial Variations In The Subsurface Salinity Of Lake Charles, Louisiana : An Investigation Of Saline Sources, Alexandria Suding
LSU Master's Theses
One of the most pressing issues facing groundwater managers is saltwater intrusion. In coastal Louisiana this issue is especially prevalent. One location that is currently threated by saltwater intrusion is the industrial area of Lake Charles, Louisiana, where three high chloride areas have been detected within the underlying Chicot aquifer. Three sand units of the Chicot aquifer are present in Lake Charles: the 200-foot (200’) sand, the 500’ sand, and the 700’ sand. Groundwater with elevated chloride concentrations was first noticed by industries in the early 1970s. An initial investigation determined that the northern and southern bodies had formed by …
Predicting Mechanical Properties Of Southern Pine Lumber With Nondestructive Measurements, Jacob Romer
Predicting Mechanical Properties Of Southern Pine Lumber With Nondestructive Measurements, Jacob Romer
LSU Master's Theses
Predictive models were developed for stiffness and bending strength of southern pine 2x6, eight ft. lumber using nondestructive measurements of stresswave velocity, density and visual characteristics such as knots, slope of grain and rate of growth. To account for local areas of weakened material due to knots and slope of grain, a grid system was developed to quantify general knot size and location. Multiple regression models were created using these physical and visual measurements. Two sets of models were developed: one that removed influential samples with abnormal wavespeeds (greater than 18,000 ft./s) indicative of poor wood quality; and, models that …
Forensic Bibliography: Reconstructing The Library Of George Wythe, Linda K. Tesar
Forensic Bibliography: Reconstructing The Library Of George Wythe, Linda K. Tesar
Library Staff Publications
The Wolf Law Library at the College of William and Mary initiated a project to re-create the library of George Wythe, the founding father of American legal education. A relatively small number of Wythe’s books are still extant today; for some volumes, there is strong documentary evidence to prove conclusively he owned specific editions of particular titles. Additionally, four bibliographies with varying levels of substantiating information provide insight into the contents of Wythe’s library. Examination of these sources launched an excursion into bibliographic history and rare book collecting that illuminates the difficulties in attempting to establish the exact editions contained …

Study On Effects Of Supply Voltage Asymmetry And Distortion On Induction Machine, Prashanna Dev Bhattarai
LSU Master's Theses
Performance of induction motor supplied with asymmetrical and nonsinusoidal supply voltages is studied in this thesis. Theory of induction motor is first presented for sinusoidal symmetrical supply voltages. Equations for the torque, losses, currents and efficiency are derived. Appropriate changes are made to apply this theory to induction motors operating at nonsinusoidal and asymmetrical supply voltages. Single phase equivalent circuit of the induction motor is presented for both asymmetrical and nonsinusoidal supply voltages. The equations governing operating characteristics are presented. Machine torque, losses, current and efficiency for asymmetrical and nonsinusoidal supply voltages are compared with the same for sinusoidal symmetrical …
Uncertainty Quantification Of Film Cooling Effectiveness In Gas Turbines, Hessam Babaee
Uncertainty Quantification Of Film Cooling Effectiveness In Gas Turbines, Hessam Babaee
LSU Master's Theses
In this study the effect of uncertainty of velocity ratio on jet in crossflow and particual- rly film cooling performance is studied. Direct numerical simulations have been combined with a stochastic collocation approach where the parametric space is discretized using Multi-Element general Polynomial Chaos (ME-gPC) method. Velocity ratio serves as a bifurcation parameter in a jet in a crossflow and the dynamical system is shown to have several bifurcations. As a result of the bifurcations, the target functional is observed to have low-regularity with respect to the paramteric space. In that sense, ME-gPC is particularly effective in discretizing the parametric …
Experimental Fragility Analysis Of Aluminum Storm Panels Subject To Windborne Debris, Taylor C. Alphonso
Experimental Fragility Analysis Of Aluminum Storm Panels Subject To Windborne Debris, Taylor C. Alphonso
LSU Master's Theses
The research presented in this thesis focused on the derivation of experimental fragility curves for windborne debris (WBD) impact risk assessment of building envelope components (BECs) with ductile behavior (in particular, aluminum storm panels) within the performance-based hurricane engineering (PBHE) framework. Using a pneumatic wind cannon, rod-type WBDs were fired at aluminum storm panels to represent real-life WBD impact hazard. The experimental data from testing were used to derive the probability of failure relative to specific damage measures (DMs) versus its corresponding interaction parameter (IP). These experimentally derived probabilities were compared with results that are available in the literature and …
Scientific Modeling & Scientific Realism : A View From Biological Morphology, Bradley Morgan Wood
Scientific Modeling & Scientific Realism : A View From Biological Morphology, Bradley Morgan Wood
LSU Master's Theses
In the ongoing philosophical debates between scientific realists and antirealists, scientific modeling is often taken as an exemplar antirealist scientific methodology due to the abstract, idealized, and metaphorical nature of most scientific models. I argue against the antirealist view and in favor of a realist view of scientific modeling as it is performed in biological morphology. On my view, morphological modeling is a type of what I call multiperspectival modeling, which involves multiple related models deployed to represent a single target phenomenon. I show how multiperspectival morphological modeling can be incorporated into the version of scientific realism developed by Richard …
Learning And Identification Of Wireless Network Internode Dynamics Using Software Defined Radio, Benjamin Elliott Carroll
Learning And Identification Of Wireless Network Internode Dynamics Using Software Defined Radio, Benjamin Elliott Carroll
LSU Master's Theses
The recently developed paradigm of cognitive radio wireless devices has been developed with the goal of achieving more customizable and efficient spectrum utilization of commonly used wireless frequency bands. The primary focus of such spectrum utilization approaches has been to discern occupancies and vacancies over portions of the wireless spectrum without necessarily identifying how specific radio frequency (RF) devices contribute to the temporal dynamics of these occupancy patterns within the spectrum. The aim of this thesis is to utilize a hidden semi-Markov model (HSMM) statistical analysis to infer the individual occupancy patterns of specific users from wireless RF observation traces. …
The Unequal Distribution Of Professional Autonomy In Schools, Joseph Cleary
The Unequal Distribution Of Professional Autonomy In Schools, Joseph Cleary
LSU Master's Theses
This qualitative study examines the ways in which educators interpret and respond to government interventions in public schools. I conducted semi-structured interviews with eleven teachers and two principals at two public high schools in Baton Rouge, Louisiana . By comparing the perceptions of educators at a low-performing school (which serves high percentages of minority and low-income students) with perceptions of educators at a high-performing school (which serves fewer numbers of minority and low-income students), this study demonstrates how an educator’s sense of autonomy relates to students’ socioeconomic backgrounds. Findings show that educators, who work in schools with high numbers of …
Impacts Of Artificial Reef Addition On The Nekton Community Of Louisiana Marsh Ponds: A Before-After-Control-Impact Analysis, Kari Elizabeth Klotzbach
Impacts Of Artificial Reef Addition On The Nekton Community Of Louisiana Marsh Ponds: A Before-After-Control-Impact Analysis, Kari Elizabeth Klotzbach
LSU Master's Theses
Louisiana’s coastal estuaries are dynamic, highly variable environments that provide nursery areas for numerous recreationally and commercially important species. Louisiana’s coastline is constantly changing due to natural and anthropogenic processes, and it is important to know how nektonic species are impacted by such changes. This study sought to assess the effects of introducing a hard substrate artificial reef on the nekton community of a Louisiana estuary. A before-after-control-impact (BACI) design was used to assess the impacts of artificial reef addition on nektonic fishes and crustaceans in four shallow marsh ponds near Empire, Louisiana. Marsh ponds were sampled by purse seine …
Blind Ldpc Encoder Identification, Tian Xia
Blind Ldpc Encoder Identification, Tian Xia
LSU Master's Theses
Nowadays, adaptive modulation and coding (AMC) techniques can facilitate flexible strategies subject to dynamic channel quality. The AMC transceivers select the most suitable coding and modulation mechanisms subject to the acquired channel information. Meanwhile, a control channel or a preamble is usually required to synchronously coordinate such changes between transmitters and receivers. On the other hand, low-density parity-check (LDPC) codes become more and more popular in recent years due to their promising capacity-approaching property. The broad range of variations in code rates and codeword lengths for LDPC codes makes them ideal candidates for future AMC transceivers. The blind encoder identification …
Teaching Mirr To Improve Comprehension Of Investment Performance Evaluation Techniques
Teaching Mirr To Improve Comprehension Of Investment Performance Evaluation Techniques
Journal of Economics and Finance Education
NPV and IRR are frequently used to evaluate investment performance, yet when they conflict many firms base capital budgeting decisions on IRR, though NPV is superior in specific cases. Teaching the MIRR technique should reinforce academia’s preference of the NPV technique. The reinvestment assumptions of NPV and IRR are implicit and hidden from students, while the calculation of the MIRR technique forces explicit decisions regarding the investment and discounting of interim cash flows. Thus, by teaching the MIRR calculation students may gain a better understanding of the differences between the three techniques reinforcing the primacy of NPV.
Wet Meadow Plant Associations, Malheur National Wildlife Refuge, Harney County, Oregon, John A. Christy
Wet Meadow Plant Associations, Malheur National Wildlife Refuge, Harney County, Oregon, John A. Christy
Institute for Natural Resources Publications
In July 2012, we sampled 131 plots in wet meadow habitat at the southern end of the Malheur National Wildlife Refuge. Analysis of the data identified eleven different plant associations: Alopecurus pratensis, Carex aquatilis var. aquatilis, Carex nebrascensis, Carex pellita, Carex praegracilis, Carex sheldonii, Distichlis spicata, Juncus balticus, Leymus triticoides, Phalaris arundinacea, and Sparganium eurycarpum. Plant associations spanned a wetland gradient from seasonally moist to seasonally or perennially flooded, but surface water had left most stands at time of sampling. Mean Wetland Indicator Status scores help to place the plant associations within gradients in soil moisture and alkalinity. The Alopecurus …
Two-Step Arithmetic Word Problems, Enrique Castro-Martínez, Antonio Frías-Zorilla
Two-Step Arithmetic Word Problems, Enrique Castro-Martínez, Antonio Frías-Zorilla
The Mathematics Enthusiast
This study uses the perspective of schemes to analyze characteristics of arithmetic word problems that can influence the process of translation from the verbal statement to an arithmetical representation. One characteristic that we have detected in the two-step word problems is the presence of one or two connections (nodes) in schemes that represent them, and this paper explores whether the number of nodes affects the activation of the associated schemas. With students from the 5th and 6th grades of elementary school (11 and 12 years of age), we analyze the written productions and would stress that the number of connections …

Trajectory Of A Problem: A Study In Teacher Training, Alain Kuzniak, Bernard Parzysz, Laurent Vivier
The Mathematics Enthusiast
Problems are frequently used in mathematics to introduce and convey new notions and skills. Hence, teachers transform and adjust those problems to their students' level. The present study focuses on this transformation process on the particular case of a geometric problem posed by two teacher educators in one French Institute for Teacher Training. The whole process is described as a trajectory of the problem through various institutions from training center to secondary school and back. Before presenting the notion of trajectory of the problem, some elements about a general theoretical frame which refers to didactics of mathematics are presented.
Primary School Teacher’S Noticing Of Students’ Mathematical Thinking In Problem Solving, Ceneida Fernández, Salvador Llinares, Julia Valls
Primary School Teacher’S Noticing Of Students’ Mathematical Thinking In Problem Solving, Ceneida Fernández, Salvador Llinares, Julia Valls
The Mathematics Enthusiast
Professional noticing of students’ mathematical thinking in problem solving involves the identification of noteworthy mathematical ideas of students’ mathematical thinking and its interpretation to make decisions in the teaching of mathematics. The goal of this study is to begin to characterize pre-service primary school teachers’ noticing of students’ mathematical thinking when students solve tasks that involve proportional and non-proportional reasoning. From the analysis of how pre-service primary school teachers notice students’ mathematical thinking, we have identified an initial framework with four levels of development. This framework indicates a possible trajectory in the development of primary teachers’ professional noticing.

The Complete Plus-Minus: A Case Study Of The Columbus Blue Jackets, Nathan Spagnola
Theses and Dissertations
A new hockey statistic termed the Complete Plus-Minus (CPM) was created to calculate the abilities of hockey players in the National Hockey League (NHL). This new statistic was used to analyze the Columbus Blue Jackets for the 2011-2012 season. The CPM for the Blue Jackets was created using two logistic regressions that modeled a goal being scored for and against the Blue Jackets. Whether a goal was scored for or against the team were the responses, while events on the ice were the predictors in the model. It was found that the team's poor performance was due to a weak …

Response Of Materials To Various Shock Loading Conditions Generated By Plate Impact Experiments, Gifford W. Plume Iv
Response Of Materials To Various Shock Loading Conditions Generated By Plate Impact Experiments, Gifford W. Plume Iv
Open Access Dissertations
The response of materials to shock loading has been investigated through use of a plate impact experimental technique. A single stage gas gun was utilized to drive projectiles to velocities between 50-500 m/s, facilitating investigations into low to moderate shock loading conditions. Temporal records of the dynamic events were captured with the use of commercial manganin stress gauges that were embedded within layers of test material.
Within this thesis, there is a bimodal theme. The first portion of this thesis investigated the spall fracture of cast irons with varying microstructure. Although the study of the spall fracture of materials is …
