Concept Mapping: Effects On Content Knowledge And Engagement With Content In Elementary Students’ Persuasive Writing, Melissa E. Gardner

Theses and Dissertations--Curriculum and Instruction

This comparative pre-test/post-test quantitative study investigated the effect of an instructional strategy using concept mapping as a graphic organizer on the quality of persuasive writing compositions produced by fourth grade elementary school students. Six fourth grade classes were assigned as intact groups to three conditions: concept mapping treatment, four square treatment, and control. Participants wrote a pre-test essay prior to treatment. Treatment consisted of an instructional unit collaboratively developed by the researcher and classroom teachers on persuasive writing. Instruction for the three treatment groups was the same except for type of graphic organizer used (Concept Map, Four Square, or none). …

The Use Of Contrastive Analysis In Code-Switching From Appalachian English Dialect To Standard English Dialect, Shayla D. Mettille

Theses and Dissertations--Curriculum and Instruction

This study examined the use of an intervention, Contrastive Analysis (CA), with fourth-graders’ writing in a Central Appalachian elementary school. The purpose was to improve the use of Standard English in students’ writing in Appalachia by decreasing the number of vernacular features typically used in the writing. The researcher collected data through Consent and Assent Forms, interviews with the fourth-grade teacher, classroom observations and an accompanying CA observation evaluation rubric, pre- and post-writing prompts, selected writings and Writer Self-Perception Scale (WSPS), as well as communication data. Data analysis was accomplished for both the prompts, writing pieces and the WSPS scores. …

Biomechanical Analysis Of Race Walking Compared To Normal Walking And Running Gait, Jaclyn D. Norberg

Theses and Dissertations--Kinesiology and Health Promotion

Human locomotion is phenomenon that is extraordinarily complex. It is evident that a complete description of locomotion involves consideration of kinematics, kinetics, and muscle activity of the extremities in all of their various movements. Race walking (RW) is a form of upright locomotion that differs from normal walking and running by its form dictated by the International Amateur Athletics Federation (IAAF). Despite the similarities to both normal walking (NW) and running (RU), RW has not been the subject of equally intensive investigations.

This study explores the comprehensive biomechanics of race walking and how it compares to NW and RU. A …

The Effect Of Fluid Periodization On Athletic Performance Outcomes In American Football Players, Christopher W. Morris

Theses and Dissertations--Kinesiology and Health Promotion

For decades strength and conditioning professionals have been seeking optimal training volumes and intensities to yield maximum performance outcomes without the onset of injury. Unfortunately, current studies apply experimental training techniques without considering the individuals’ response to the imposed training load. Due to the vast genetic variability and extraneous environmental factors that affect one’s ability to recover, results from such studies are controversial and inconclusive. Athlete monitoring systems offer an objective assessment that is purported to evaluate an individual’s physiological readiness to adapt to an overload stimulus and thus allow for daily manipulations in training loads (i.e., fluid periodization). However, …

A Microsimulation Of Novel Intersection Designs, Aman Kinfemichael Woldetinsae

Civil and Environmental Engineering Master's Project Reports

The focus of this project is to see how a turbo roundabout and a protected intersection designs behave when they are applied on two study sites in Portland, OR. PTV VISSM is used to model, analyze and compare the performances of these designs with the existing intersection. In addition, the best features of the protected intersection and the turbo roundabout were combined to create a new intersection design that is safer for the bicyclists and also performs better than the existing intersection.

The analysis is conducted for five different volume scenarios for both the study sites. The results of the …

Key Aspects For Lrfd Implementation For Driven Pile Capacity By Dynamic Methods, Natalie R. Ehrlich

Civil and Environmental Engineering Master's Project Reports

Inputs and interpretation procedures for pile wave equation analysis, which correlates measured field dynamic driving response to axial pile static capacity, are highly dependent on site-specific soil conditions and field practices. The 6^th Edition of the AASHTO LRFD Bridge Design Specifications provide generalized guidelines for pile design, but do not account for variability in region-specific soils and field practices. A comprehensive literature review of region-specific resistance factor recalibration efforts across the U.S. has given insight into the range of implementation issues encountered, especially the key decisions around choosing a restrike (BOR), along with measures of efficiency and treatment of …

Dynamic Effect Of Light And Turbulence On Algal Photosynthetic Rate: A Water-Quality Model, Andres R. Rivas

Civil and Environmental Engineering Master's Project Reports

Several studies provide evidence that algal photosynthetic rates depend on various changing factors such as light attenuation, temperature, and nutrient limitation (Chapra, 1997). However, recent papers show that turbulence and photosynthetic rate dynamics is also important (Ross, 2006). In this study, the photosynthetic rate model used is the one proposed by Chapra (1997), where it depends directly on temperature, nutrient and light limitation factors. At the same time, the effect of turbulence or random-walk of algae particles in the water column was also introduced in this model. To account for this factor, the model added was that proposed by Ross …

Comparing Mode Shares For Non-Residential Destinations In Urban And Suburban Environments, Tasnia Subrin

Civil and Environmental Engineering Master's Project Reports

To ensure facility for multimodal transportation is one of the most important concerns in today's transportation sector, with initiatives being taken to make multimodal transportation popular. The built environment variables have a strong relationship with transportation mode choice, but whether that relationship holds true in urban and suburban neighborhoods in the same manner has not been considered. Using data for three non-residential land uses, this research explores whether the built environment variables in suburban areas influences mode share like it does in urban areas. We used survey data conducted at the establishments regarding respondents' travel characteristics from a previous study, …

Stress, Anxiety Symptomology, And The Need For Student Support Services For University Freshmen Of First-Generation Status, Low-Ses Backgrounds, And Those Registered With Disabilities, Kelly Dale Allison

LSU Master's Theses

Three populations of concern for professional social workers in higher educational settings include first-generation college students (FGCSs), students from low socio-economic (low-SES) backgrounds, and students with disabilities. As the national demand for degrees in higher education rises both socially and economically, the push for young adults’ postsecondary success becomes increasingly crucial. In college and university settings, a significant portion of students may be classified as FGCSs, low-SES, or may be registered with a disability. Examining these vulnerable populations within higher education settings, particularly regarding stress and anxiety symptomology, can help social workers recognize the social, developmental, and academic inhibitions that …

Nuclear Structure Of 26si And 32cl For Astrophysics, Liudmyla Afanasieva

LSU Doctoral Dissertations

We studied the nuclear structure of two isotopes, 26Si and 32Cl, important for understanding stellar explosions like novae and Type I X-ray bursts. The 31S(p,γ)32Cl reaction rate influences the enrichment of sulfur observed in some nova ejecta, but the uncertainty in the rate spans as much as an order of magnitude and arises from uncertainties in the properties of resonances corresponding to excited states in 32Cl. We populated states in 32Cl via the 10B(24Mg,2n)32Cl reaction using the Argonne Tandem-Linac Accelerator System (ATLAS), with a 75 MeV beam of 24Mg bombarding a 200 μg/cm2 10B target. Gamma rays emitted from recoiling …

Non-Marital Families And (Or After?) Marriage Equality, Deborah A. Widiss

Articles by Maurer Faculty

If, as is widely expected, the Supreme Court soon holds that bans on same-sex marriage are unconstitutional, it is almost certain that the decision will rely heavily on the Court’s reasoning in United States v. Windsor. I strongly support marriage equality. However, a decision that amplifies Windsor’s conception of the harm caused by exclusionary marriage rules could set back efforts to secure legal recognition of, and respect for, non-marital families. That is, Windsor rectified a deep inequality in the law—that same-sex marriages were categorically denied federal recognition—but in so doing it embraced a traditional understanding of marriage as superior to …

Griggs At Midlife, Deborah A. Widiss

Articles by Maurer Faculty

Griggs v. Duke Power, the Supreme Court case that held that policies that disproportionately harm minority employees can violate federal employment discrimination law even without evidence of “intentional” discrimination, recently turned forty. Griggs is generally celebrated as a landmark decision, but disparate impact’s current relevance (and its constitutionality) is hotly debated. Robert Belton’s The Crusade for Equality in the Workplace offers a rich and detailed history of the strategic choices that led to the plaintiffs’ victory in Griggs. This Review uses Belton’s history as a jumping off point to consider the contemporary importance of disparate impact in efforts to challenge …

Book Review. Reviving Fiscal Citizenship, Ajay K. Mehrotra

Articles by Maurer Faculty

In recent years, numerous lawmakers, policy analysts, and scholars have been decrying the many defects of the present U.S. income tax system. Few have attempted to defend our return-based mass income tax. This essay reviews Learning to Love Form 1040, Lawrence Zelenak’s stirring and persuasive defense of a simplified version of our present federal income tax system. In contrast to the conventional economic critiques, Zelenak explores the underappreciated social, cultural, and political benefits of a return-based, mass income tax. Chief among these, he argues, is the existing regime’s potential to raise the tax consciousness of the average citizen and to …

Saccharomyces Cerevisiae Tel1 & Tel2 Role In Dna Double-Strand Break Repairs, Tommy Nhan Trieu

LSU Master's Theses

Genomic DNA is constantly in danger of being damaged by endogenous cellular processes and exogenous agents. Eukaryotes have mechanisms, collectively termed the DNA damage response, that detect and repair DNA damage. After a double-stranded break occurs, protein complexes are recruited to the break site to promote resection. Two main protein kinases involved in DNA repair are the Tel1 and Mec1 proteins. Recent studies have found that the Tel2 protein binds to both the Tel1 and Mec1 proteins and a point mutation of TEL2 on the 129th amino acid disrupts this interaction. Since both of the Tel1 and Mec1 proteins are …

Prison Privatization And Inmate Labor In The Global Economy: Reframing The Debate Over Private Prisons, Alfred C. Aman, Carol J. Greenhouse

Articles by Maurer Faculty

The pragmatics of privatization offer terrain for a critical understanding of the relationship between government and business under the conditions associated with the globalization of neoliberal capitalism. Prison privatization is especially significant in this context, given the fact that—for privatization advocates and critics alike, in the United States and elsewhere—prisons represent a bellwether for broader questions about the scope of government. We review the recent history of prison privatization in the United States from the vantage point of the policy responses to the privatization movement more generally, to highlight the various factors that, over time, made private prisons iconic of …

Effects Of Light Quality And Light Quantity On The Growth Kinetics Of A Louisiana Native Microalgal/Cyanobacterial Co-Culture, Jonathan Zell Barnett

LSU Master's Theses

One of the most important factors controlling the growth of microalgae is light. Light quality and light quantity have a dramatic effect on the production of biomass, lipids and pigments of microalgae. In this research, a native Louisiana co-culture containing Chlorella vulgaris (microalgae) and Leptolyngbya sp (cyanobacteria) was studied to determine the effects of various wavelength distributions and irradiance levels on growth kinetics. Growth rates, biomass levels, lipid contents and chlorophyll-a production was examined in batch cultures to determine which color light was optimum for cultivation. At 80 µmol/m^2-sec the species shifted from microalgae dominant to cyanobacteria dominant. The impact …

White Manhood In Louisiana During Reconstruction, 1865-1877, Arthur Wendel Stout

LSU Doctoral Dissertations

Economic, political, and social landscapes changed for white men in Louisiana after the Civil War. Suffering displacement, business interruption, property confiscation, and lower social and political standing vis-à-vis the former slaves, white men’s standing in every realm seemed diminished, including their core identity as men. It was important to them and to their families for white men to regain a sense of competence as men. Using letters, diaries, and court cases involving white people with strong connections to Louisiana during the Reconstruction era, this dissertation analyzes the gendered problems that white men and their families sought to resolve. Newspaper articles, …

Forfeiture Of Confrontation Rights And The Complicated Dynamics Of Domestic Violence: Some Thoughts Inspired By Myrna Raeder, Aviva A. Orenstein

Articles by Maurer Faculty

In this essay and memorial to my friend and colleague, Myrna Raeder, I examine forfeiting the right of confrontation in the context of domestic violence cases. In 2004, Crawford v. Washington the United States Supreme Court reinterpreted the Sixth Amendment, requiring that for “testimonial statements” to be offered against the accused, the speaker must appear in court, or, if unavailable, must have been subject to cross-examination previously. The practical effect of Crawford was to exclude many out-of-court statements that had previously been admissible. Nowhere was the effect of Crawford more striking than in domestic violence cases, where victims often make …

Synthesis With Hypergraphs, Christopher Thomas Alvin

LSU Doctoral Dissertations

Many problems related to synthesis with intelligent tutoring may be phrased as program synthesis problems using AI-style search and formal reasoning techniques. The _x000C_first two results in this dissertation focus on problem synthesis as an aspect of intelligent tutoring systems applied to STEM-based education frameworks, specifically high school geometry. Given a geometric _x000C_figure as input, our technique constructs a hypergraph representing logical deduction of facts, and then traverses the hypergraph to synthesize problems and their corresponding solutions. Using similar techniques, our third result is focused on exhaustive synthesis of molecules. This synthesis process involves bonding sets of basic, molecular `fragments' …

People’S Perception Of Free Trade And Economic Sophistication, Igor Kuznetsov

LSU Master's Theses

The question of which factors form people’s attitudes toward free trade has occupied scholars’ minds for no less than two decades. Many theories were suggested in an attempt to explain why some individuals strongly support protectionist policies while others prefer trade liberalization. These explanations range from classical economic models of factors of production to nationalism, the fear of foreign cultures, and gender differences. The contribution of this paper is that I combine economic and non-economic approaches, introducing the possibility that individuals may think from an economic perspective or draw on other considerations depending on what they know about economics. That …

Evaluating The Effects Of Silicon And Nitrogen Fertilization On Wheat Production, Brandon White

LSU Master's Theses

Silicon (Si) fertilization provides numerous benefits to plants which can in turn lead to improved crop yields. Field studies were established at multiple sites in Louisiana on alluvial flood plain soils to establish an optimum application rate for CaSiO3 slag for wheat (Triticum aestivum) and determine which parameters contribute to grain yield increases. Treatments were arranged in a randomized complete block design with four replications consisting of twelve treatments: a factorial combination of two N (101 and 145 kg ha-1) and five Si rates (0, 1, 2, 4.5, and 9 Mt ha-1 as calcium silicate slag - CaSiO3, 14% Si), …

Potential For Geothermal Energy In Northern Louisiana: Analysis Of The Subsurface Environment In Union And Morehouse Parishes, Tessa Shizuko Hermes

LSU Master's Theses

Efforts to mitigate greenhouse gas emissions and reduce dependence on fossil fuels have led to renewed focus on the exploration and development of alternative energy production. One such option is hydrothermal binary geothermal energy production from geothermal reservoirs with temperatures of at least 100 °C at depths no greater than 5 km. In the U.S., such systems have the potential to provide 5,400 % of 2013 total U.S. energy consumption. This study evaluates the potential for geothermal energy systems implementation in Morehouse and Union Parishes, Louisiana, by using publicly available bottom hole temperature (BHT), mud weight (MW), logged formation top …

Evaluating The Interspersal Procedure Using Free Access To A Competing Reinforcer, Catherine Rose Lark

LSU Master's Theses

Previous research has shown that interspersing additional easy problems among difficult target problems increases target problem fluency and student preference for an assignment. Nonetheless, there have been some contradictory findings concerning the efficacy of the interspersal procedure, so more research is needed to determine whether teachers should use this procedure for academic assignments. The current study attempted to replicate and extend the research on this procedure by using access to a competing reinforcer (an iPad) and a homework analogue. Fourth-grade students were given access to an iPad, but were told to work first for 10 minutes each on a control …

The Creation And Reflection Of A Solo Show: Corner Of 26 And Lost, Margaret Mcgurn

LSU Master's Theses

We knew coming into this two-year M.F.A. program in June of 2013 that our thesis would culminate in December of 2014 with the performance of a solo show that we would each write and perform ourselves. So as early as out first summer here, we were encouraged to get the ball rolling with potential ideas. The thought this project was to not only give us practice at devising work, but also put a show in our back pocket. So, when we graduated, we would have a full-fledged show that we could take on the road and perform anywhere with little …
