Money In And Money Out: The Effects Of Race And Gender On Campaign Finance, Bertha Gabriela Vitela

LSU Doctoral Dissertations

The role of campaign finance in the success of a candidate is undeniable. Research currently examines the role of race and gender as separate actors in determining how well candidates are able to fund their campaigns. This project uses an intersectional framework arguing that race and gender together combine to influence the kinds of money candidates receive as well as where and how they spend it. Using data from 2006 and 2008 Congressional election cycles, this analysis takes a first step in determining well how Black women and Latinas are able to fund campaigns for the House of Representatives. The …

Aristotle's Quarrel With Socrates: Friendship In Political Thought, John Boersma

LSU Doctoral Dissertations

Friendship played an outsized role in ancient political thought in comparison to medieval and modern political philosophies. Most modern scholarship has paid relatively little attention to the role of friendship in ancient political philosophy. Recently, however, scholars are increasingly beginning to investigate classical conceptions of friendship. My dissertation joins this growing interest by examining the importance of friendship in the political thought of Socrates and Aristotle. Specifically, I analyze the divergent approaches that Socrates and Aristotle take to politics and trace these distinct approaches to their differing conceptions of friendship. Through an examination of two Platonic dialogues—the Lysis and the …

Self-Healing Composite Of Thermoset Polymer And Programmed Super Contraction Fibers, Guoqiang Li, Harper Meng

College of Engineering Patents

A composition comprising thermoset polymer, shape memory polymer to facilitate macro scale damage closure, and means for molecular scale healing has the ability to repair structural defects by a bio-mimetic, close-then-heal process. The shape memory polymer serves to bring surfaces of a structural defect into proximity, after which the healing means moves into the defect and provides molecular scale healing. The means for molecular scale healing can be a thermoplastic, such as fibers, particles or spheres, which are heated to or above the thermoplastic's melting point, and then the composition is cooled below that melting temperature. The compositions can not …

Mosquito Image Classification Using Convolutional Neural Networks, Sumanth Vissamsetty

LSU Master's Theses

Human life has always been affected by insects, especially mosquitoes, since it's early beginnings. This pesky insect acts as a vector that transmit pathogens through feeding on our blood, spreading life-threatening diseases like Zika Virus, Malaria, Dengue fever, Chikungunya and more. It is important to prevent these mosquitoes from harming humans and one way to do so is to control the mosquito population, or mosquito abatement as it is commonly known. It is important to note that not all mosquitoes are the same and each of them live, reproduce and attack in their own unique way. Hence it is crucial …

Pragmatics And Pedagogy In University Level Spanish Second Language Textbooks, Vanessa M. Cardenas

LSU Master's Theses

This pragmatic and pedagogical investigation analyzes six university level Spanish second language textbooks (L2Ts) used in the classroom setting.

(2008), Conexiones (2010), and Interacciones (2013). The purpose of this investigation is to closely examine if the L2Ts communicatively present the speech acts of requesting, refusing, and apologizing, and address forms, with sufficient pragmatic context for the L2 learner to acquire native-like production. The results have shown that the speech acts under …

Exploring Geochemical Proxies For Identifying Cryptic Sequence Boundaries In The Geologic Past Using Modern Bahamian Analogues, Evan B. Magette

LSU Master's Theses

Previous studies of carbonate diagenesis have suggested that bulk Sr concentrations and inorganic δ¹³C values may be a useful proxy for identifying cryptic sequence boundaries in meteorically altered limestones due to geochemical processes associated with carbonate mineral stabilization in cement precipitation in the meteoric diagenetic environment. However, it is possible that natural geochemical variation in sediments may produce geochemical shift which could be misinterpreted as a cryptic sequence boundary. To test this, the Two Pines roadcut containing a previously identified protosol on Eleuthera, Bahamas, which has been affected by vadose meteoric diagenesis was sampled for bulk geochemical analysis. …

Faculty Publications

A new heterogeneous Fenton catalyst, Fe-impregnated biochar catalyst (Fe-BC) was synthesized and evaluated in detail for its catalytic activity with sulfate radical under various conditions. The optimum conditions for the removal of Eriochrome Black T (EBT) by Fe-BC were determined as 0.27 g/L K2S2O8 (PS) and 0.5 g/L Fe-BC for 0.1 g/L EBT, and which resulted 85–88% removal efficiency within 2 h. The effective oxidation of EBT was observed over a pH range of 2–4 and temperature of 25–45 °C and maintained EBT removal efficiency of 77.6–92.7%. Under optimum conditions, the catalytic activity was faster in the order of PS …

A Comprehensive Assessment Of Rape Myths, Hookup Culture, And Social Structure Among Heterosexual Individuals, Timothy Thomas Reling

LSU Doctoral Dissertations

This dissertation study is an examination of the relationship among rape culture, hookup culture, and social structure (i.e. regular and patterned forms of interaction over time which crystalize ideological constructs and channel behavior in specific ways). Since few efforts have examined female-on-female rape myth acceptance, I first explore collegiate perceptions of female-on-female rape to denote the influence of heteronormative discourse in guiding myths regarding survivor culpability, offender culpability, and situational contexts. Second, I develop, pilot, and validate a psychometric instrument to exclusively assess female-on-female rape myth acceptance. Finally, I comparatively assess the mediating influence of heteronormativity on the association between …

Sacroiliac Joint Fusion In Nulliparous And Parous Females And Males, Meredith Aulds

LSU Master's Theses

Previous research shows that sacroiliac (SI) joint fusion is age and sex dependent. Older individuals—specifically starting in the fifth or sixth decade of life—are more likely to develop SI fusion. Females have a lower frequency of SI joint fusion than males, perhaps due to pregnancy or parturition. This study examines the relationship between SI joint fusion with both sex and parity status in females. The issue is whether the prevalence of SI fusion in nulliparous females is more similar to that of males or parous females. The sample consists of 46 nulliparous females, 119 parous females, and 158 males from …

The present study uses a phenomenological approach to gain parents’ experiences related to culturally responsive and competent practices in their child(ren)’s schools. Interviews were conducted with 10 culturally diverse parents with children in preschool and/or elementary school. The interviews were transcribed verbatim, coded for common themes and analyzed for the frequency and prevalence of the themes in preschool vs. elementary school settings. An analysis of the interviews revealed 6 themes related to culturally competent and responsive practices in school settings. The …

A Retrospective Analysis And Method Validation Of Postmortem Interval Estimation In Louisiana, Sophia Reck

LSU Master's Theses

Forensic anthropologists are often called upon to assess the postmortem interval (PMI; i.e. time since death) of remains in varying states of decomposition and skeletonization. These assessments rely on familiarity with general taphonomic sequences and processes, in addition to experience with how these processes present in local environments and conditions. Assessment using such qualitative methods is a subjective process. Therefore, some researchers have developed formulae whose purpose is to estimate PMI in an objective format. In these instances, the resultant PMI estimation formulae were developed using local data and therefore have the potential for local applicability. Additionally, for some regions, …

Concentration Flow Cells For Efficient Salinity Energy Recovery With Carbonized Peat Moss And Molybdenum Disulfide Electrodes, Haihui Zhu

LSU Master's Theses

The globally extractable salinity gradient (SG) energy from the mixing of seawater and river water is estimated to be 3% of worldwide electricity consumption. Here we applied carbonized peat moss (CPM) electrodes and molybdenum disulfide (MoS₂) electrodes to a concentration flow cell that is capable of harvesting SG energy based on the electrode (pseudo-)capacitance together with the Donnan potential. The CPM electrodes were made from the visually inexhaustible peat moss by a facile pyrolysis process. With two identical CPM electrodes and a cation-exchange membrane, the cell produced a peak power density of 5.33 W m^-2 and an …

A State Of Impermanence: Buddhism, Liberalism, And The Problem Of Politics, Cory Michael Sukala

LSU Doctoral Dissertations

This dissertation explores the relationship of Buddhist political thought and liberal political thought at the level of first principles. I will examine the tension created by the Buddhist view of political life as instrumental and secondary to man's being as a function of the transition of the Buddhist world into the sphere of Western political life, which views the role of politics as primary to man's nature. In Part I, this will be accomplished through a consideration of the origins of political life and the foundation of the political state in each tradition as viewed through the themes of human …

Twitter Use In Hurricane Isaac And Its Implications To Disaster Resilience, Kejin Wang

LSU Master's Theses

Disaster Resilience is the capacity of a community to ‘bounce back’ from disastrous events. Most studies rely on traditional data such as census data to study community resilience. With the advent of social media era, the new data source gives us an opportunity to explore the application of Twitter data to better understand disaster resilience. A research question is: does Twitter use correlate with disaster resilience? In other words, will communities with more Twitter users be more resilient to disasters, presumably because they are more likely to be better informed? The underlying issue is that if there are social and …

The New British Christianity Of C.S. Lewis, Thomas Kemp

LSU Master's Theses

The emergence of C.S. Lewis as a popular author known for Christian content during the second half of the twentieth century provides an ideal case study for the transformation of religiosity within Britain. As religious behavior shifted from institutional adherence to private experience, Lewis became a ‘popular theologian’ who represented Christianity both for Christians – who looked to him for spiritual inspiration– and for non-Christians – who treated his views as representative of contemporary Christianity. By analyzing the reception, representation, and use of Lewis (his figure and his work) throughout the twentieth-century and into the twenty-first, it becomes clear that …

Fermi Surface, Possible Unconventional Fermions, And Unusually Robust Resistive Critical Fields In The Chiral-Structured Superconductor Aube, Drew J. Rebar, Serena M. Birnbaum, John Singleton, Mojammel Khan, J. C. Ball, P. W. Adams, Julia Y. Chan, D. P. Young, Dana A. Browne, J. F. Ditusa

Faculty Publications

The noncentrosymmetric superconductor (NCS) AuBe is investigated using a variety of thermodynamic and resistive probes in magnetic fields of up to 65 T and temperatures down to 0.3 K. Despite the polycrystalline nature of the samples, the observation of a complex series of de Haas-van Alphen (dHvA) oscillations has allowed the calculated band structure for AuBe to be validated. This permits a variety of BCS parameters describing the superconductivity to be estimated, despite the complexity of the measured Fermi surface. In addition, AuBe displays a nonstandard field dependence of the phase of dHvA oscillations associated with a band thought to …

Naus, Justin Greene

LSU Master's Theses

A collection of poems and nonfiction vignettes, naus entails a navigation of my experience with Tourette Syndrome and, consequently, what it can mean to have a noisy body. Rather than situate noise as a negatively construed iteration of sound, I contend that, following the work of Michel Serres, it is instead a disruption within a system, a parasitical interception, an affective force that has the potential to alter the positions and orientations of a given constellation of bodies, human or otherwise. Similar to how sound, as a verb, can be understood as “to fathom” or “to make sense of,” naus …

Quantifying Coherence In A Transdiagnostic Sample: A Methodological Investigation Of Computationally-Derived Coherence Using Ambulatory Assessment, Taylor L. Fedechko

LSU Master's Theses

Schizophrenia is a clinical diagnosis assigned to individuals that experience positive (e.g., hallucinations and delusions), negative (e.g., blunted affect), and disorganized (e.g., incoherent speech) symptoms. One particularly disabling symptom is incoherence, which is defined as the meaning-based relationship between ideas. This symptom can drastically affect an individual’s quality of life by affecting areas such as social and occupational functioning. Currently, the mechanism behind this symptom is unknown and requires further study. One way to examine incoherence is to understand its level of expression in other clinical populations. With the advent of computationally-derived natural language processing (NLP), coherence can be quantified …

Estimating Sex Using The Human Mandibular Canine, Brittney Blevins

LSU Master's Theses

Sexual dimorphism can be quantified in human mandibular canines; therefore, these teeth can be used to estimate sex of skeletonized individuals. This study complements and expands previous research by comparing mesiodistal diameter (MD), buccolingual diameter (BL), and crown area of human mandibular canines. Measurements were taken from a sample of skeletal individuals from the Terry Collection (n=677), the Maxwell Museum of Anthropology Skeletal Collection (n=86), and a random sample of dental casts from the James K. Economides Orthodontic Case File (JKE, n=624), for a total study sample of 741 males and 677 females. Both left and right canines were measured, …

The Lowly Ones, Cassie Meredith Benson Grillon

LSU Master's Theses

The Lowly Ones is a collection of short stories that interrogates the meaning of beatitudes written about in Luke 6:20–23 in the Bible. The characters in these stories navigate complex moral situations that examine the meaning behind the values presented in the beatitudes: mercy, sorrow, persecution, etc. These women face the challenges of faith in surprising ways, through the notoriety of a dead sister, the fascination with a lower-class neighbor, and the mysterious purchase of an exotic bird. This collection thoroughly erases the fictitious line religion and society draw between saints and sinners.

Using Entheseal Length To Infer Locomotor Type, Antonio R. Otero

LSU Master's Theses

An enthesis is a marking (tuberosity or impression) on bone where a muscle or tendon attaches and it can be influenced by age, sex, physical activity, and muscle size. This study ascertains whether entheses, long bones, and their respective ratios can be used as an indicator for mode of locomotion in four primate species: Ateles geoffroyi (Geoffroy’s spider monkey), Colobus guereza (mantled guereza), Hylobates lar (lar gibbon), and Macaca mulatta (rhesus monkey). Seven entheses on four long bones were chosen based on importance of the muscle in relation to specific locomotor types, use in other studies, and …
