Queer Emplotment: Lesbian Caretaking In North American Canonical Fiction From 1980 – 2011., Penelope Gay Dane

LSU Doctoral Dissertations

My dissertation argues that lesbian caretaking in late 20th century and early 21th century North American fiction disrupts normative temporalities while repairing damage protagonists sustain from intra-familial trauma. Aligned with queer studies’ growing interest in representations of time, my project explores this paradox of lesbian representation. How can lesbian characters be both reparative and disruptive? Lesbian characters in Alice Walker’s The Color Purple (1980); Dorothy Allison’s Bastard Out of Carolina (1992); and Louise Erdrich’s Shadow Tag (2010) are reparative as they clean up the psychological and physical damage caused male violence, sexual abuse, and neglectful mothers. Yet their caregiving disrupts …

Methods For The Characterization Of Deep-Sea Benthic Megafauna In The Vicinity Of The Deepwater Horizon Macondo Well, Stephanie Marie Sharuga

LSU Doctoral Dissertations

Soft-sediment benthic environments are amongst the largest marine ecosystems in the world and play important roles in many ecosystem functions. In recent years, exploitation of resources and unintentional impacts on deep-sea benthic environments has increased. The Deepwater Horizon oil spill of 2010 in the northern Gulf of Mexico (GoM) represented a prime example of this. The oil spill not only highlighted deficiencies of data and information on baseline conditions, but also represented an opportunity to learn more and develop better methods for the future. Deep-sea imaging platforms such as autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs) have been …

Chemistry And Application Of Pulses As Value-Added Ingredients In Processed Foods, Darryl Holliday

LSU Doctoral Dissertations

Chemical characterization of pulses allows for varying rates of water absorption, least gelation capacity, and retrogradation depending on species. Nutritionally, pulses are good sources of protein while being low in fat. Pulses deliver a readily bioavailable food form of several key minerals. Additionally, they deliver fiber. The insoluble fiber components are both natural and formed resistant starch in addition to the oligosaccharide content. Therefore, pulses can serve both a nutritional and functional role when used as a value-added ingredient. Meat patties were produced from beef and 23 different pulses at 35%, 42.5%, and 50% ratios. Each patty was tested for …

Evolving Time Surfaces And Tracking Mixing Indicators For Flow Visualization, Farid Harhad

LSU Doctoral Dissertations

The complexity of large scale computational fluid dynamic simulations (CFD) demands powerful tools to investigate the numerical results. To analyze and understand these voluminous results, we need to visualize the 3D flow field. We chose to use a visualization technique called Time Surfaces. A time surface is a set of surfaces swept by an initial seed surface for a given number of timesteps. We use a front tracking approach where the points of an in initial surface are advanced in a Lagrangian fashion. To maintain a smooth time surface, our method requires surface refinement operations that either split triangle edges, …

Differential Examination Of Disgust In Spider, Blood-Injection, And Contamination Fear: Self-Reported And Attention-Based Assessment Of Differences, Whitney Shay Jenkins

LSU Doctoral Dissertations

Biased attention toward threat has been demonstrated across anxiety disorders as well as among nonclinical samples. While such studies have produced findings of attentional bias for fear-related or threatening stimuli, other types of emotionally laden stimuli have been ignored. This study sought to examine the experience and impact of disgust on individuals experiencing various types of anxiety, which may play a more significant role than fear in some disorders such as obsessive-compulsive disorder (OCD) and some specific phobias. Specifically, this study examined self-reported disgust and attentional bias in relation to disgust and threatening stimuli. A modified dot-probe task with pictorial …

Untangling Earth System Responses Recorded In Sulfate's Sulfur And Oxygen Isotopes At The Dawn Of Multicellular Life And Today, Bryan Alan Killingsworth

LSU Doctoral Dissertations

Major Earth system perturbations in the deep past and today are recorded in sulfate sulfur and oxygen isotopes, as examined here in three cases. (1) Sedimentary sulfate record of the “Marinoan Oxygen-17 Depletion” (MOSD) event, implies ultra-high CO2 atmosphere at ~635 Ma after global glaciation. MOSD duration is constrained by correlating its most complete record to radiometric dates. Barium sulfate layers in South China sediments show the MOSD in lower layers but persistently absent up section. Carbon-13 correlation locates the MOSD within dated intervals from other sites, yielding a 0 - 0.99 Myr duration. Thus, sedimentary constraint on this non-steady-state …

Characterization Of A Water Soluble, Non-Ionic, Helical Poly(Α-Amino Acid), Wayne Huberty

LSU Doctoral Dissertations

A water soluble, non-ionic, rodlike polymer, PEGL, was synthesized and characterized in efforts to synthesize a novel model polymer to study stiff polymers in solution. The rodlike system is likely stiff due to a high relative percent helicity in water up to 50 °C, measured by circular dichroism, the observation of liquid crystalline domains in water, and from the slope measured from conformation plots supplied by GPC/MALS; however, it also apparent the system is aggregating in both a 2 mM azide solution and a buffer (200 mM NaNO3 + 20 mM NaH2PO4 + 2 mM NaN3), in corroboration of negative …

Coworking: Crafting Lives Alongside Each Other, Claire Frances Taylor

LSU Doctoral Dissertations

Coworking is a form of alternative work arrangement in which communities of individuals share common office and work space but are most often employed by different employers within different fields/industries (Foertsch, 2011). Despite its growing prevalence, coworking is nearly absent from the organizational literature. The present mixed methods study introduced and defined the construct of extent of coworking. Extent of coworking is conceptually defined in this research as the degree to which an individual spends her/his workweek coworking. Qualitative literature review was conducted to establish this construct, and qualitative interview data provided support for the definition. Using job crafting and …

More Than Met The Eye: Industry In The Antebellum Gulf South, Michael Sean Frawley

LSU Doctoral Dissertations

1860 was a census year. Census marshals spread out across the United States to record many different aspects of American society, including information on population, agriculture and, most importantly for this study, manufacturing. The antebellum Gulf South has traditionally been viewed as a region with little industrial development. But, both contemporaries and historians based their view of industry in the Gulf South on what was recorded in the census schedules. Alabama, Mississippi, and Texas were portrayed in the census as areas with little industrial development. But, as many historians have discovered, there were errors in the 1860 census, especially errors …

C. S. Lewis And The Premodern Rhetorical Tradition: The Abolition Of Man As Rhetoric And Philosophy Of Education, Nicholas Ryan Pertler

Electronic Theses and Dissertations

This interpretive project begins with the following question: How does The Abolition of Man by C. S. Lewis (1898-1963) function as a rhetoric and philosophy of education to open up meaningful alternatives to modern education? Although Lewis originally composed and delivered the text as three lectures in response to the felt educational concerns of his age, in its published form The Abolition of Man still offers relevant insight on the topic of education in contemporary times. Scholarship on Lewis has yet to fully appreciate exactly how his educational ideals align with the premodern rhetorical tradition, but this project argues that …

The Influence Of Colorism And Hair Texture Bias On The Professional And Social Lives Of Black Women Student Affairs Professionals, Rhea Monet Perkins

LSU Doctoral Dissertations

The Influence of Colorism and Hair Texture Bias on the Professional and Social Lives of Black Women Student Affairs Professionals “If it was so honorable and glorious to be black, why was it the yellow-skinned people among us had so much prestige?” Zora Neal Hurston (1942) understood the privilege and oppression associated with colorism. “Colorism is the allocation of privilege and disadvantage according to the lightness or darkness of one’s skin” (Burke, 2008, p. 17). Colorism is the systematic preference for lighter skin tones over darker tones and stems from larger racial systems impacting education, income, marriageability, job placement, housing …

Occurrence And Effects Of Repeated Trauma Exposure In Emergency Medical Personnel, Casie Ann Probst

Electronic Theses and Dissertations

This study focuses on the prevalence and severity of post-traumatic stress symptoms in Emergency Medical Services (EMS) personnel. Summative PTSD Checklist (PCL-C) scores were collected and analyzed from 102 active, adult EMS professionals working in Pennsylvania. Data analysis shows EMS professionals are experiencing severe post-traumatic stress symptoms at a higher rate than the general public. The severity and prevalence of EMS post-traumatic stress symptoms are comparable to those of American veterans returning from active combat zones in Iraq. Based on the results, several suggestions are proposed regarding how to effectively minimize the experience of post-traumatic stress symptoms in EMS professionals.

Examination Of The Influence Of Instructional Coaching On Teacher And Principal Behavior, Attitudes, And The Resultant Learning Environment, Cynthia Pulkowski

Electronic Theses and Dissertations

Over the past few decades, stakeholders in education have placed significant emphasis on student achievement. Educational reform in the United States and internationally has set ambitious goals for student learning. Additionally, educational reform demands transformations in classroom practices for teachers to become agents of change. As such, teacher professionalism is at a threshold; moral purpose and change agentry are implicit in good teaching and effective change (Fullan, 1993). Systems do not change themselves; rather, they change through the actions of individuals and small groups (Fullan, 1993). In light of this notion, and in the face of educational reform and accountability, …

Crystal Structure, Electronic Structure, And Physicochemical Characterization Of Diamond-Like Semiconductors Prepared By High-Temperature Solid-State Synthesis, Kimberly Ann Rosmus

Electronic Theses and Dissertations

Diamond-like semiconductors (DLSs) have structures that are derived from cubic or hexagonal diamond. The compositions of DLSs are predictable and flexible allowing for properties to be tuned to target technological applications. The fields of photovoltaics, thermoelectrics, and nonlinear optics (NLO) are in need of materials with improved efficiencies for practical devices. Toward the goal of discovering advanced materials, systematic studies of DLSs allowing for the elucidation of structure-property and composition-property relationships were carried out. Here, in-depth structural, physicochemical, and computational studies have been performed on several DLSs to correlate the crystal and electronic structure with the physicochemical properties.

The DLSs, …

Nietzsche And Comedy: Provocative Laughter Amidst A Tragic Philosophy, Michael C. Rudar

Electronic Theses and Dissertations

Friedrich Nietzsche is well known as the philosopher of the tragic view of life. Because we are part of the world of becoming the tragic view maintains that human beings are given over to certain limits that we cannot transcend. These include ourselves as finite beings, the recognition that noumenal knowledge is not possible and, because we are subject to the flux of existence, that life can be both painful and destructive. However, for Nietzsche the tragic view of life ought not result in humorless resignation. Just as he appeals to ancient Greek tragedy to demonstrate how the ancients remained …

Touching Plantation Memories : Tourists And Docents At The Museum, Eddie Arnold Modlin Jr

LSU Doctoral Dissertations

Plantations are one of the long-standing symbols of the U.S. South. Today, almost four hundred former plantation sites are museums. Over the last fifteen years a sustained, critical consideration of how slavery is remembered at these sites has developed in the academic literature. Geographers have argued that remembering slavery at these sites is geographic not only because most of these sites are in the South, but also because the public spatializes memory in certain ways at these historic places. To date, much of the memory literature about plantation museums focuses on the roles of these museums and their staff in …

Genetics And Functions Of Herpes Simplex Virus Type-1 Membrane Proteins Ul20/Gk In Virion Envelopment And Entry, Anu Susan Charles

Contractional Tectonics: Investigations Of Ongoing Construction Of The Himalaya Fold-Thrust Belt And The Trishear Model Of Fault-Propagation Folding, Hongjiao Yu

LSU Doctoral Dissertations

This dissertation focuses on the kinematic evolution of contractional tectonics: the Himalayan fold-thrust belt along the collisional orogenic belts, and growth of the basement-cored monoclines in Colorado Plateau. Ongoing Himalayan growth is generally thought to be dominated by duplexing and/or extrusion processes. Duplexing models highlight accretion of material from the subducting plate to the over-riding orogenic wedge, whereas extrusion models focus on up-dip translation of a block bounded by out-of-sequence faults. Here, a primary outstanding question involves the uncertain relationship of the Berinag thrust and the Tons thrust, structures with displacements of >80 km and >40 km, respectively. The uncertainty …

University Education In A Postmodern Era: Building A Narrative Ethic Of Civil Communication In The Classroom, Jill Dishart Leontiadis

Electronic Theses and Dissertations

This project responds to the question: How can educators quell communicative classroom incivilities (CI) that are currently harming teaching and learning? Sources of CI in a postmodern United States university classroom involve: student entitlement, lack of institutional support for a growing contingent faculty, and incongruent values about appropriate classroom communication. Unlike preceding historical time periods that maintained a shared communicative ethic stemming from antiquity to modernity, postmodernity presents an unprecedented challenge to teaching and learning where there can be no assumed shared ethic of appropriate communicative classroom communication. Postmodernity as an age of coexisting and contentious narratives, this project argues …

The Smartpen As A Mediational Tool For Learning Language And Content Areas: The Case Of English Learners In Mainstream Classrooms, Rae Mancilla

Electronic Theses and Dissertations

The use of mobile devices for supporting the instruction of second language (L2) learners is an emerging and rapidly growing area of inquiry. Previous research on mobile assisted language learning (MALL) has concentrated on the development of isolated linguistic skills through a common set of mobile technologies, such as PDAs and iPods, with limited attention given to alternative mobile devices or situations of L2 learning that require the simultaneous learning of language and academic content (Wu, Jim Wu, Chen, Kao, Lin, & Huang, 2012; Viberg & Grönlund, 2012; 2013). In particular, little is understood about how English Learners (ELs) educated …
