Brahms's Ein Deutsches Requiem: Dialectic And The Chromatic Middleground, Patrick Tuck

LSU Doctoral Dissertations

Brahms’s Ein deutsches Requiem (1868) has been the focus of much scholarly research. The present study focuses specifically on the work’s dialectic: the presentation and resolution of a conflict between mortal suffering and eternal joy. It takes an Schenkerian approach to the tonal content of the piece, which provides a musical reflection of the human spiritual journey to the afterlife. It examines how Brahms brings his chosen texts to life with the aid of musical processes such as mixture, register transfer, coupling, covering lines, and contrasting textures. The present study will cite previous authors who have noted the opposing forces …

The Formation Of A Style: Selected Early Works By Hugo Wolf, Jure Rozman

LSU Doctoral Dissertations

Hugo Wolf’s (1860–1903) most pronounced talent was in marrying music and poetry in novel ways, which is clearly demonstrated by his more than 240 art songs. In his early years Wolf composed a series of works for piano solo, published for the first time in 1974 by the Musikwissenschaftlicher Verlag in Vienna. This paper explores these and other formative works in detail, focusing on music-theoretical issues, but also placing them in historical context by means of a brief biography which includes recent discoveries regarding Wolf’s Slovene lineage.

Investigation Of Superficial Dose From A Static Tomotherapy Beam, Koren Suzette Smith

LSU Master's Theses

Abstract Purpose: The TomoTherapy planning system is capable of creating treatment plans that deliver a homogeneous dose to superficial targets. It is essential that the planning system accurately predicts dose to the surface and superficial depths from beams directed at every angle in the axial plane. This work concentrates on measuring and modeling the dose from a static TomoTherapy beam at normal and oblique incidence. It was hypothesized that superficial doses measured from a static TomoTherapy beam agree with doses calculated by the TomoTherapy planning system to within 5% of the maximum dose for angles of incidence from 0¢ª-83¢ª. Methods: …

Rate Change Effects On Acoustic Duration Measures On An Adolescent Who Stutters, Valerie Jean Courville

LSU Master's Theses

The purpose of this study was to determine if reduced rate techniques have an effect on speech motor coordination of an adolescent. A literature review revealed that a reduced rate technique consistently promoted more fluent speech; however, the cause of that increase in fluency is not known. This study proposed three specific questions to determine if there was a shortening of the /s/ phoneme in clustered contexts when compared to singletons, if reducing the rate would cause the adolescent to produce more adult-like shortening patterns, and if the reduced rate technique caused a decrease in stuttering events. One eleven year …

Chromosomal Stability And Epigenetic Modifications Of Fibroblast Cells Used For Nuclear Transfer, Angelica Maria Giraldo Gomez

LSU Doctoral Dissertations

Investigations into the importance of the nuclear integrity of the donor cell prior to nuclear transfer (NT) are limited. In Experiment 1, the proliferative characteristics, chromosomal stability and level of histone phosphorylation in cell lines established by explants and enzymatic dissociation at different population doublings (PDs) were investigated. The cells divided at a constant rate and cell cycle length increased only at the end of the proliferative stage. The level of aneuploidies was high and remained elevated throughout the study independent of the technique used to establish the primary culture. High levels of multinucleated cells and abnormal spindle configurations were …

Visualizing The Menstrual Cycle: Effects Of A Redesigned Cycle Diagram On Community College Biology Students' Learning, Francesca Maria Mellieon-Williams

LSU Doctoral Dissertations

This mixed methods, exploratory study investigated the importance of the menstrual cycle diagram for understanding human reproduction. Several theories were used to support this study including Visual Design Theory (Tufte, 1990, 1997, 2001), and Human Constructivist Theory (Mintzes, Wandersee, Novak 1998). The two sexuality education programs used by society, abstinence-only programs and comprehensive sex education programs were compared to illustrate how this study applies to the current state of sexuality education in the United States. Community college students from two institutions in the southern region of the United States, registered in five introductory biological science courses, participated in a unit …

Genotypic Variability And Inheritance Of Iron And Zinc In Sweetpotato, Michael William Courtney

LSU Master's Theses

Sweetpotato [Ipomœa batatas (L.) Lam.] is a major subsistence crop in Sub-Saharan Africa, where iron and zinc deficiency in humans is an important health problem. A sweetpotato cultivar suited for subsistence farming, with high iron and zinc concentration, would be important in alleviating these deficiencies. The main objective of this research was to identify the extent of genetic variability of iron and zinc concentration in sweetpotato germplasm. An important subcomponent of this research was to determine the heritability of iron and zinc in sweetpotato. Protocol development studies were also conducted to aid in determining proper sampling technique. The results of …

An Analysis Of The World Shrimp Market And The Impact Of An Increasing Import Base On The Gulf Of Mexico Dockside Price, Pawan Poudel

LSU Master's Theses

As a result of increased cultured activities, the world shrimp market has been expanded significantly during the past two decades. Because the growth in world supply has exceeded that of growth in demand, the deflated world shrimp price has fallen significantly since the mid-1980s. While a large producer of shrimp (primarily in the Gulf of Mexico), the United States is also the world’s largest importer. In general, the Gulf of Mexico dockside price is determined by the world export price and, as such, the Gulf of Mexico price has fallen sharply in recent years. This study quantifies the impact on …

The first phase of the study used questionnaires from the primary caregivers of 161 children. The questionnaires allowed for an examination of family history as a function of a child’s socioeconomic level (+/- high school level of maternal education), educational placement (+/- receipt of services by a speech language clinician), and clinical status (+/- profile consistent with a diagnosis of SLI). The second phase of the study included interviews that were collected from 17 families …

Sensory Characteristics And Optimization Of A Low-Sodium Salt Formulation And Its Food Application, Armen Khachatryan

LSU Doctoral Dissertations

Excessive consumption of sodium is associated with high blood pressure in people. Reduction of sodium intake and replacement of salt with salt substitutes are an essential component of the primary prevention of hypertension. Potassium chloride is the most widely used salt substitute. However, when used in large amounts, it imparts bitterness and metallic aftertaste. Therefore, bitterness masking agents need to be used in salt substitute formulations. L-Arginine has been reported to have bitterness masking properties. No research has yet been conducted to investigate the effects of KCl and L-Arginine on the perception of saltiness and bitterness in the mixture of …

An Empirical Analysis Of Life Tenure: A Response To Professors Calabresi And Lindgren, Ryan W. Scott, David R. Stras

Articles by Maurer Faculty

Opposition to life tenure has been steadily mounting in the legal academy and Professors Steve Calabresi and Jim Lindgren are among those leading the charge. Crucial to their argument that life tenure is fundamentally flawed is an empirical claim that the increases in average tenure among Supreme Court Justices are both dramatic and unprecedented.

In this article, the authors respond to Calabresi and Lindgren by showing that their hypothesis of dramatic and unprecedented growth in average tenure has two fundamental flaws. First, it suffers from a period-selection problem. Rendering the data using longer or shorter periods blunts or eliminates the …

Peforming Louisiana: The History Of Cajun Dialect Humor And Its Impact On The Cajun Cultural Identity, Debrah Royer Richardson

LSU Doctoral Dissertations

Cajuns, the descendants of the Acadian diaspora begun in 1755, chose to live a largely isolated existence in Louisiana until elements in the nineteenth century began concerted efforts to assimilate the Cajuns. By the beginnings of the twentieth century, the dual challenges of enforced schooling and the prohibition of spoken French affected the Cajun sense of pride. Around the same time, outsiders (satirists from Louisiana who were not of Cajun descent) used the Cajun dialect, in publications and on the radio, to humorously skewer Louisiana politics. Over the last century, Cajun dialect humor has evolved along specific lines that have …

Tourmalinities In Neoproterzoic Metaevaporitic Deposit Of Duruchas Formation, Damar Belt, Central Namibia, Haiting Sun

LSU Doctoral Dissertations

Tourmalinites from a well-developed meta-evaporite sequence in the Neoproterozoic Duruchaus Formation of central Namibia contain tourmalines with chemical and textural features that are excellent recorders of their environment of formation. Unlike most other meta-evaporitic deposits, this tourmalinite locality exhibits only minor deformation. The tourmalinites form as finely laminated units ca. 1 m thick within a sequence of quartzites, mica schists, dolomitic marbles, and carbonate breccias. Well-preserved pseudomorphs are considered to replace a variety of evaporitic minerals. The meta-sedimentary rocks of the Duruchaus Formation have been interpreted as representing lacustrine, playa lake, fluvial, and non-marine evaporite deposition in an intracontinental rift …

Strategies For Establishing Spartina Alterniflora On Newly Constructed Marsh Terraces In Coastal Louisiana, Ashley Wilson Mullens

LSU Master's Theses

Marsh terracing is an innovative restoration technique being used in shallow, open water marshes in coastal Louisiana. When properly constructed and planted with an applicable plant species, terraces promote sediment deposition and accumulation by reducing wave energy. Although used extensively for marsh creation, little published information is available on techniques for establishing vegetation on marsh terraces. The goal of this research was to determine the optimal planting season and most effective plant growth form of Spartina alterniflora for establishing vegetation on newly constructed marsh terraces. Study objectives were to: 1) compare survival and growth rates of different plant growth forms …

Design, Synthesis, And Conformational Studies Of Peptides Containing α,α-Disubstituted Amino Acids, Jia Wang

LSU Doctoral Dissertations

C^α,α-disubstituted amino acids (ααAAs) are widely utilized to conformationally constrain peptides. Several pentapeptides containing dipropylglycine (Dpg) at alternating positions and their α-amino acid counterpart L-norvaline (Nva) analogues were synthesized to fully investigate the impact of Dpg on peptide backbone structure in aqueous solution. CD, VCD and NMR spectral analysis suggest that Dpg containing peptides adopt more ordered structures relative to their Nva containing analogues. The central residues (Ala, Thr, Tyr, Val) and the charged side-chains of Glu and Lys play important roles in the degree of peptide folding. Hydrophobic and branched residues (Val, Tyr) at the …

Can I Play Too? A Look At Minor Party Entrance And Success In U.S. Gubernatorial Elections, Jay Douglas Ducote

LSU Master's Theses

New minor political parties and their candidates face many challenges. Most of challenges have been examined on the national level in the previous literature. By examining ballot access laws and campaign finance regulations in all 50 U.S. states, this thesis argues that differences in the restriction to ballot access and campaign finance laws account for some of the variation in the number of new minor party candidates who run for governor in each state as well as the percentage of the vote they receive. Using a coding for ballot access laws and campaign finance stringency, as well as several control …

Spatial And Temporal Distribution Of Solar Radiation In Louisiana, Michael Ulric Kemp

LSU Master's Theses

The purpose of this study is to examine temporal and spatial trends in surface global horizontal solar radiation in Louisiana using a 30-year dataset (1961-1990) of the four stations in Louisiana from the National Solar Radiation Database (NSRD) and a 6-year dataset (2001-2006) of the 25 stations in the Louisiana Agriclimatic Information System (LAIS). Three of the four NSRD stations exhibit a downward linear trend in surface solar radiation over the 30-year period of record, similar to the global trends uncovered in previous studies. Only one station exhibits a slightly upward trend. Surface solar radiation exhibits a positive correlation with …

Analysis Of Trade On El Salvador Post Dollarization, Jorge Raul Rivera

LSU Master's Theses

Dollarization has been suggested as an option for emerging economies. This policy might, among other goals, promote trade between a country adopting the dollar and the United States. Recent research suggests that adopting a common currency increases bilateral trade. Those findings have been widely critiqued for the lack of consistency over different currencies specially the case of dollarization. This thesis is primarily concerned with the impact of dollarization in El Salvador regarding bilateral trade flows. Utilizing the framework of the Gravity Model, bilateral trade flows for 13 trading partners of El Salvador were examined. This study found that dollarization has …

Population Change And Social Vulnerability In The Wake Of Disaster: The Case Of Hurricanes Katrina And Rita, Candice A. Myers

LSU Master's Theses

Previous sociological research on natural disasters has highlighted how various dimensions of social vulnerability influence the impact of, and recovery from, such disasters. This research contributes to the literature by examining population change in the wake of Hurricanes Katrina and Rita, with an explicit focus on how social vulnerability moderates this relationship. Using data from the U.S. Census Bureau, I construct a macro-level Social Vulnerability Index (SoVI) for the impacted region and then use regression analysis to explore how various dimensions of social vulnerability are related to population change in the six months following the storms. The results reveal a …

Uncomfortable Performances: Discovering A Subversive Scenario For Rape Discourse, Annamaria Ruffino

LSU Master's Theses

Current trends in representations of rape show a new fascination with a rape scenario, a fascination that puts a normative slant on discourse surrounding rape. Normalizing the rape scenario carries various consequences for women; the first and foremost is that it turns the experience of rape into an entertainment commodity, thus causing women’s voices to be appropriated into dominant discourses and the capitalist project. One possible way to circumvent this normalization is to look toward feminist performance strategies in order to subvert this rape scenario and the discourses surrounding it from within. In this thesis, I explore ways to accomplish …

Blakely's Silver Lining; Sentencing Guidelines, Judicial Discretion, And Crime, Joanna Shepherd

UC Law Journal

The Supreme Court's recent decisions in United States v. Booker and Blakely v. Washington, invalidating mandatory criminal sentencing guidelines, could have the unexpected benefit of reducing crime. This Article is the first to use regression analysis to explore the relationship between sentencing guidelines and crime. It shows that adoption of guidelines is associated with significant increases in crime, contrary to the expectations of many of the original supporters of sentencing guidelines.

After developing several economic theories about the relationship between guidelines and crime, the author investigates this relationship empirically using a large, state-level data set. The analysis shows that guidelines …
