The Impact Of Student Centered Learning Strategies In Middle School Earth Science, Zane Jay Whittington Jan 2014

The Impact Of Student Centered Learning Strategies In Middle School Earth Science, Zane Jay Whittington

LSU Master's Theses

Research continues to reinforce that student centered classrooms and interactive engagement (IE) strategies, when used effectively, can produce considerable gains compared to traditional instruction methods. In this study, IE strategies, primarily modeling instruction, were compared to traditional instruction in a middle school classroom to determine if IE strategies would have an impact in two specific areas: graphing ability and science reasoning skills. Class mean scores on tests were compared over time to show that IE strategies produced greater gains in graphing and science reasoning than traditional instruction for one group. The other group did not see significant differences in graphing …

Evolution Of Supply Chain Collaboration: Implications For The Role Of Knowledge, Michael Gravier, M. Theodore Farris Jan 2014

Evolution Of Supply Chain Collaboration: Implications For The Role Of Knowledge, Michael Gravier, M. Theodore Farris

Marketing Department Faculty Journal Articles

Increasingly, research across many disciplines has recognized the shortcomings of the traditional “integration prescription” for inter-organizational knowledge management. This research conducts several simulation experiments to study the effects of different rates of product change, different demand environments, and different economies of scale on the level of integration between firms at different levels in the supply chain. The underlying paradigm shifts from a static, steady state view to a dynamic, complex adaptive systems and knowledge-based view of supply chain networks. Several research propositions are presented that use the role of knowledge in the supply chain to provide predictive power for how …

An Analysis Of "Printemps D'Amour" (Op.40) And "L'Union" (Op,48): Two Programmatic Piano Solos By Louis Moreau Gottschalk, Sam Vaden Jan 2014

An Analysis Of "Printemps D'Amour" (Op.40) And "L'Union" (Op,48): Two Programmatic Piano Solos By Louis Moreau Gottschalk, Sam Vaden

LSU Master's Theses

Close analyses of two works by Gottschalk demonstrate, not just his consummate skill in evoking and sustaining extra-musical imagery, but also his firm control of harmony, motivic development, and form. In Printemps d'amour (1855), a mazurka inspired by Gottschalk's love for Ada McElhenney, a romance develops between two distinct theme-actors, both of whom grow ever more entwined. Comparison with Chopin's mazurka op. 50, no. 2, points out general similarities and profound differences. Analysis of L'Union (1862) follows, presenting a pasticcio rife with narrative and irony. The former manifests as a battaglia; the latter, as denial of listeners' expectations. Comparison with …

Tonal And Topical Coherence In Brahms's Op.10 Ballades, Jacob Joel Gran Jan 2014

Tonal And Topical Coherence In Brahms's Op.10 Ballades, Jacob Joel Gran

LSU Master's Theses

Johannes Brahms composed the op. 10 ballades in the summer of 1854 while living at the Schumann household in Düsseldorf. These pieces are unique within the instrumental ballade repertoire in that they form a collection of ballades published as a single opus. How did Brahms intend the four ballades to cohere as a group, as opposed to a collection of independent pieces? The problem in identifying coherence lies as much within the genre of the instrumental ballade as it does within the musical features of op. 10. These pieces demonstrate a wide range of musical topics, some of which appear …

Quantifying Phase Configuration Inside An Intact Core Based On Wettability Using X-Ray Computed Tomography, Dinara Dussenova Jan 2014

Quantifying Phase Configuration Inside An Intact Core Based On Wettability Using X-Ray Computed Tomography, Dinara Dussenova

LSU Master's Theses

The ability to evaluate rock and fluid properties on the order of a few microns opens new areas in reservoir engineering and reservoir simulation. Multiple studies have been done on the application of x-ray computed tomography (microCT) for the pore-scale evaluation of fluid interfaces and rock-fluid interaction. A majority of the fluid flow governing interactions occur at the pore scale level and is usually overseen on large reservoir scales. Hence, it is important to carefully investigate such interactions. Multi-fluid-phase distribution and interaction of two immiscible fluids such as oil and water is one of the most important and constantly investigated …

Examination Of The Differential Effectiveness Of Interdependent And Dependent Group Contingencies In Reducing Disruptive Behavior In The Classroom, Kelsey Lynn Hartman Jan 2014

Examination Of The Differential Effectiveness Of Interdependent And Dependent Group Contingencies In Reducing Disruptive Behavior In The Classroom, Kelsey Lynn Hartman

LSU Master's Theses

Disruptive behavior in the classroom negatively affects all students’ academic engagement, achievement, and behavior. Group contingencies have been proven effective in reducing disruptive behavior as part of behavior interventions in the classroom. The Good Behavior Game is a classwide intervention that employs an interdependent group contingency to diminish disruptive behavior. Previous research comparing the effects of the different group contingencies has been inconclusive, inconsistent or unable to rule out sequence effects. This study employed an alternating treatments design across 3 elementary classrooms to compare the effectiveness of interdependent and dependent group contingencies in decreasing disruptive behavior. Results showed that the …

Giftedness And Overexcitability : Investigating The Evidence, Daniel Lawrence Winkler Jan 2014

Giftedness And Overexcitability : Investigating The Evidence, Daniel Lawrence Winkler

LSU Doctoral Dissertations

Many scholars of gifted education have often argued and believed that gifted individuals are neurologically overexcitable while non-gifted persons are not (Chang & Kuo, 2013; Harrison & Haneghan, 2011; Piechowski, 1979, 2006; Silverman, 2000a; Siu, 2010; Tieso, 2007a). This means that gifted persons are more sensitive, intuitive, empathic, and physically and emotionally aware. Some scholars have suggested that this significant degree of overexcitability may even mean that gifted persons are morally superior to non-gifted persons (Silverman, 1994). Over the past thirty years, this relationship between overexcitability (OE) and giftedness has become increasingly popular, as many websites, textbooks, and researchers have …

Spatial And Temporal Analysis Of Selected Birth Defects And Risk Factors In The Baton Rouge, Louisiana Metropolitan Statistical Area, Aimee H. Moles

LSU Doctoral Dissertations

About three percent of all infants are born with a congenital defect each year ranging from minor variants to life threatening abnormalities. The investigation and treatment of these problems is both costly and emotionally trying for all involved. Finding their origins is a complex process. Birth defects create the ultimate mystery in terms of trying to tease out the various influences created by the environment of both the infant and the mother. Two genetically different individuals are simultaneously affected both by their individual makeup and by the outside world impacting the air they breathe, the food they eat, and the …

Recalled Bullying: Development Of A Measure To Identify Childhood Victims And Perpetrators By Adults, Melissa Munson Jan 2014

Recalled Bullying: Development Of A Measure To Identify Childhood Victims And Perpetrators By Adults, Melissa Munson

LSU Doctoral Dissertations

The purpose of the study was to develop a psychometrically sound measure of recalled childhood bullying by adults who were either victims or perpetrators of this behavior. In order to accomplish this, a measure of childhood bullying, the Peer Interactions in Primary School (PIPS) Questionnaire, was modified into a retrospective measure in order to quantify recollections of childhood bullying by adults. Specifically, the modified PIPS (PIPS-R) was created to identify adults who identified themselves as bullies, victims, or bully-victims during their childhood or who do not recall having been a bully or a victim. Eight hundred and twelve undergraduate college …

Performing Joseph Cornell's Chronotopes Of Assemblage, Sarah Kathryn Jackson Jan 2014

Performing Joseph Cornell's Chronotopes Of Assemblage, Sarah Kathryn Jackson

LSU Doctoral Dissertations

In this project I study Joseph Cornell’s practices of art-making through a performative lens. Rather than focusing on his finished products, I am interested in his embodied processes of assemblage. I call on Mikhail Bakhtin’s theory of the chronotope to articulate how time and space operate within Cornell’s finished works and his processes of assemblage art. In so doing, I conceptualize Cornell’s textual chronotope, métaphysique d’éphemera or “everyday magic,” as well as his chronotopes of assemblage: wandering, archiving, collaging, and assembling. I move from the finished work to the contingencies and strategies of the performance of assemblage. This project is …

Fantini And Frescobaldi In Rome, Circa 1634: A Study Of Context And Practice, Shelby Allen Lewis Jan 2014

Fantini And Frescobaldi In Rome, Circa 1634: A Study Of Context And Practice, Shelby Allen Lewis

LSU Doctoral Dissertations

ABSTRACT This study clarifies historical evidence as applied to Italian baroque performance practices and repertoire for trumpet and pipe organ, circa 1630. It focuses upon a specific concert; the first historical record of a trumpet and pipe organ duo performing whereby the trumpeter takes a soloistic role. The details surrounding the performance, one involving trumpeter Girolamo Fantini and organist Girolamo Frescobaldi, make wonderful fodder for a more detailed musical look into 17th century Italy. Perhaps most importantly, the process outlined here can be modified and used in the study of music from virtually any genre from any musical period. Ultimately, …

The Control Of Amplitude And Direction In Bimanual Coordination, Zhujun Pan Jan 2014

The Control Of Amplitude And Direction In Bimanual Coordination, Zhujun Pan

LSU Doctoral Dissertations

Spatial coordination of bimanual movements is important when performing daily activities. Whereas, older adults and individuals with Parkinson’s disease (PD) commonly show difficulties in temporally coordinating the hands in bimanual coordination tasks, the effects of aging and Parkinson’s disease on the quality of spatial coordination between the hands are unclear. Thus, the present work investigated the impact of older age and PD on the spatial interference in a bimanual task in which 48 right hand-dominant participants (16 young adults, 16 older adults and 16 individuals with PD) drew simultaneously two lines with both hands with varied movement amplitudes (3 and …

Assimilation, A Biological Nitrogen Removal Strategy For Freshwater Ornamental Fish Hatcheries, Fatemehsadat Fahandezhsadi Jan 2014

Assimilation, A Biological Nitrogen Removal Strategy For Freshwater Ornamental Fish Hatcheries, Fatemehsadat Fahandezhsadi

LSU Master's Theses

Freshwater ornamental fish production is a major component of aquaculture in the southeastern United States. Closed recirculating aquaculture systems (RASs) allow freshwater ornamental fish hatcheries to mimic native water quality conditions for sensitive species. Total ammonia-N (TAN) removal is the major concern for closed RASs. Biological nitrification is the common method to control TAN. However, the nitrification process might be impaired in acidic water condition with pH<7. Another issue of using the nitrification process for TAN removal is that the nitrification is not sufficient to compensate for the amount of ammonia released in larval production systems because of slow growth rate of nitrifying bacteria. To address these issues, this study suggests an aerobic assimilation strategy in which fast growing heterotrophic bacteria directly convert TAN into microbial biomass. The heterotrophic bacteria needs an external carbon source. This study employed polyhydroxybutyrate (PHB) that is a solid insoluble bioplastic, as a carbon source in the aerobic assimilation process to avoid releasing carbon into the system. In order to understand the applicability of an assimilation process instead of nitrification, this study compared the ammonia-N removal rate by aerobic assimilation biofilters operating @ pH 8 and 6.5 in a batch system. The study also quantified the performance of an aerobic assimilation strategy under different continuous nitrogen loading regimes. This investigation can be used to establish the biofilter air pulsing frequency, which is the optimized air pulsing frequency that avoids clogging in the system. The results showed that there was no apparent release of carbon in the water tank. Unlike nitrification, assimilation strategy for TAN removal was not significantly different in two pH of 8 and 6.5 @ 28 ° C. The average consumption rate of the PHB was found as 21.93± 0.43 grams of PHB consumed per gram of TAN. The results from the continuous system, at a continuous feeding rate of 350 mg-N/d, suggested that the optimum air pulsing frequency through the PHB bed for releasing the excess biosolids was about 6-hour. In general, the study found that the aerobic assimilation using polyhydroxybutyrate (PHB) as a carbon source is an applicable method for ammonia-N removal particularly for freshwater ornamental fish production systems. The drawback against this approach is that the PHB beads are expensive. However, our investigations show that the average cost of the PHB beads have been decreased dramatically during the last few years. This might indicate that the assimilation using PHB beads can be a reasonable choice for ammonia-N removal particularly for freshwater ornamental fish production systems.

Everything Is Alright: Parental Positive Impression Management In Assessment Of Anxious Youth, Megan Elizabeth Kirkpatrick Jan 2014

Everything Is Alright: Parental Positive Impression Management In Assessment Of Anxious Youth, Megan Elizabeth Kirkpatrick

LSU Master's Theses

Lifetime prevalence rates of anxiety disorders in youth are substantial and range from 6-15%. Valid evidence-based assessments are therefore of critical importance in screening pediatric clients. Assessment of childhood disorders requires multi-informant data (e.g., parents, teachers, child); however, this presents a host of obstacles not found in adult assessment. No single source represents the gold standard and it is therefore up to the judgment of the clinician to integrate often conflicting information. Parents’ reports of their children's symptomology may be marred by their own anxious or depressive symptoms as well as conflict due to differing motivations, values, and goals. This …

Regulation Of Oocyte Meiotic Resumption Using Camp Modulators In Bovine In Vitro Maturation, Sarah Farmer Jan 2014

Regulation Of Oocyte Meiotic Resumption Using Camp Modulators In Bovine In Vitro Maturation, Sarah Farmer

LSU Master's Theses

In vitro maturation (IVM) is a reproductive technique critical to in vitro embryo production (IVP) in commercial livestock industries, research, and human infertility treatment. Currently, IVP has low efficiency due to an inadequate IVM system in which premature meiotic resumption results in low oocyte viability. Meiotic arrest is regulated primarily by 3’,5’-cyclic adenosine monophosphate (cAMP), and the most successful methods of improving IVM utilize cAMP modulators to maintain high intra-oocyte cAMP, delaying the onset of maturation. This thesis includes experiments comparing standard bovine IVM to a novel extended IVM method similar to the procedure described by Albuz and colleagues (Albuz …

A Toolkit For Tracking And Mediating Parametric Objects Upon Commodity Mobile Devices, Shantanu Thatte Jan 2014

A Toolkit For Tracking And Mediating Parametric Objects Upon Commodity Mobile Devices, Shantanu Thatte

LSU Master's Theses

The large number of mobile devices introduced in the market in recent years provide numerous interaction opportunities. We used commercially available products to create an interface for interaction with diverse datasets. We extended this scenario to include multiple physical instances, realizing a real-time multi-party interaction session. Tangibles act as tools and containers, in a fashion that requires their physical location and orientation to be evaluated continuously during a session. We present a technique to detect an object using only the touchscreen of a mobile device as an input, by means of touch patterns created on the screen. This helps avoid …

Failed Agricultural Impoundments: An Interdisciplinary Assessment Of Community Structure And Social Resilience, Stacy Nicole Peterson Jan 2014

Failed Agricultural Impoundments: An Interdisciplinary Assessment Of Community Structure And Social Resilience, Stacy Nicole Peterson

LSU Master's Theses

The remnants of the wetland reclamation era of the early 1900s are visible in the leveed, drained, and failed impoundments across the United States, and especially in coastal regions. The common themes of their history are flooding, restoration, and – sometimes - community resilience. The physical changes occurring during and after impoundment, and after failure includes subsidence, erosion, and flooding are well-documented. Here I construct an environmental history that integrates data on these physical changes with archival records, historical documents, site visits and personal interviews. The primary region of focus is ‘Delta Farms’ - a failed agricultural impoundment in Lafourche …

The Feasibility Of Creating A 3d Digital Skeletal Collection For Research Purposes And Museum Use, Karen Leigh Beebe Jan 2014

The Feasibility Of Creating A 3d Digital Skeletal Collection For Research Purposes And Museum Use, Karen Leigh Beebe

LSU Master's Theses

3D scanners offer many advantages to scientists and museum curators, such as a permanent digital archival record of the scanned object, the non-intrusive nature of 3D laser surface scanning, the ability to create and share a digital collection with other researchers, and the portability of recent scanners. With the purpose of determining the feasibility of creating a 3D research collection in mind, I have scanned and studied skeletal material from Wild Cane Cay and Moho Cay, Belize. I explore how the 3D model compares to the physical bone and the significance of 3D imaging to the anthropological community.

Field And Numerical Investigation Of Wave Power And Shoreline Retreat In Terrebonne Bay, Southern Louisiana, Kyle Ryan Parker Jan 2014

Field And Numerical Investigation Of Wave Power And Shoreline Retreat In Terrebonne Bay, Southern Louisiana, Kyle Ryan Parker

LSU Master's Theses

The marshland in southern Louisiana is a vital resource that many people and wildlife depend on. Terrebonne Bay was chosen for this research because it has experienced one of the largest wetland loss rates among Louisiana estuaries. Investigations of wave power and shoreline retreat rate could provide decision makers with a better understanding of the contributing wave force responsible for local shoreline retreat. A strong relationship has been shown to exist between wave power and shoreline retreat [Schwimmer (2001) and Marani et al. (2011)]. Whether or not this strong relationship exists in Terrebonne Bay is the subject of this research. …

A Study In Didactics, Jordan Cormier Jan 2014

A Study In Didactics, Jordan Cormier

LSU Master's Theses

When Sir Arthur Conan Doyle ended The Final Problem with Sherlock Holmes’ apparent death there was a mass outcry of protest from his fans to the point that myths still circulate about how young Victorian men wore black armbands in mourning. There was a reason why the Holmes stories had such a mass appeal: Sherlock Holmes, brilliant, asexual, emotionally reserved and eminently rational detective that he was, was in many ways the archetype of the ideal Victorian man. As such he struck a very deep chord with British society at the time, the extent of which his creator never quite …

Sediment Patterns In Relation To Vegetative Community Shifts At Catahoula Lake, Louisiana, Karen Doerr Latuso Jan 2014

Sediment Patterns In Relation To Vegetative Community Shifts At Catahoula Lake, Louisiana, Karen Doerr Latuso

LSU Master's Theses

The processes that control species composition and structure in wetland ecosystems are complex and controlled by many factors including seasonality, depth and duration of flooding, and nutrient dynamics. Catahoula Lake is a floodplain lake that has existed with seasonally fluctuating water levels for at least 4,000 years. The herbaceous vegetation that attracts these waterfowl is slowly being outcompeted by woody vegetation, most notably water-elm (Planera aquatica). Our general goal is to understand the processes that cause this shift, focusing on the role of sediments. Our first objective was to use historical aerial imagery to detect historical changes in plant communities …
