Musicking New Orleans Street Musicians: A Methodology For Writing About Music, Savannah Cadi Rose Ganster

LSU Doctoral Dissertations

This project argues for the use of performative writing as a methodology for writing about musical performances. An analysis of recent scholarship on music and musical performances written by performance studies scholars supports the use of performative writing in texts that address musical performances. In order to further this methodological claim, this study uses performative writing to document both historical and present day accounts of musical performances of street musicians in New Orleans. Utilizing Foucault’s theories on and Roach’s model of genealogy, Bruner’s notion of reflexive ethnography, and Small’s concept of musicking, I theorize, on a meta-methodological level, that performative …

Articulating Situated Knowledge And Standpoints In Our Responses To Contemporary Street Fiction: A Book Club Case Study With African American Women, Yvette Rachele Hyde

LSU Doctoral Dissertations

Contemporary street fiction is a form of literature that has been growing in popularity since the 1990s. Such novels are set in contemporary urban contexts and present the experiences of historically oppressed groups. Sold in venues such as independent bookstores, the Internet, barbershops, beauty salons, flea markets, street vendors, and churches (Hill, Pérez, & Irby, 2008; McClellan, 2011), this genre is especially popular among African American females. Because much of the scholarship concerning engagement with contemporary street fiction focuses on improving school literacy skills, the purpose of this study was to investigate readers’ responses in a book club held at …

Stress Tolerance Enhancement Of Rice By Genetic Manipulation Of A Bhlh-Myc2 Transcription Factor, Luis Eduardo Sanchez Timm

LSU Doctoral Dissertations

Rice yield is adversely affected by various abiotic and biotic stresses. Jasmonic acid (JA) signaling has been implicated in stress response of plants. The nuclear localized basic helix loop helix (bHLH) Myc2 transcription factor is known to be a master regulator of genes involved in the response of the JA-mediated signaling pathway during stress and plant development. Myc2 is also induced by wounding and mechanical damage, and is associated with resistance against herbivore insects. In order to understand the mode of action of Myc2 in stress response of rice, overexpresser (OE) and knock-down (KD) mutants for OsMyc2 were generated in …

The Relationships Of Word Processing In Academic Work And Student Achievement Scores On The National Assessment Of Educational Progress, Amos Glenn

Electronic Theses and Dissertations

This study is a secondary analysis of the 2011 NAEP writing test investigating the relationships between word processing in academic work and achievement test scores. Using data and methods to overcome several of the limitations found in research surrounding instructional technology, the statistical analyses constructed a table of z- scores and p-values that describe the relationship between both general use and specific uses of word processors and the total score on the NAEP writing assessment. Heuristic analysis of this table finds that there is a persistent and positive relationship between the use of word processors and writing achievement score. Specifically, …

Evolutionary Relationships Among Fungal Soybean Pathogens And Molecular Marker Development In The Genus Cercospora, Sebastian Albu

LSU Doctoral Dissertations

Cercospora leaf blight (CLB) and purple seed stain (PSS) are common soybean diseases in the Gulf South of the United States (USA). For nearly a century, Cercospora kikuchii has been considered as the only pathogen causing these diseases. However, previous reports of genetic diversity among isolates collected throughout Louisiana suggested the presence of multiple lineages or species. Recent systematic studies classified species of Cercospora using a taxonomic system based on phylogenetic analysis of five nuclear loci (legacy genes). Using a similar approach, cercosporoid fungi tentatively identified as C. kikuchii were evaluated along with 53 other species of Cercospora. No …

Mechanisms Controlling Stem Cell Differentiation, Tran Doan Ngoc Tran

LSU Doctoral Dissertations

Mesenchymal stem cells are multipotent cells that can differentiate into many cell types. However, the molecular mechanism controlling this process remains unclear. We utilized rat dental follicle stem cells (rDFSCs) and human adipose derived stem cells (hASCs) to study the mechanisms controlling osteogenesis and adipogenesis. Elevations in the intracellular Ca2+ concentration are a phenomenon commonly observed during stem cell differentiation but cease after the process is complete. The Transient Receptor Potential Melastatin 4 (TRPM4) is an ion channel that controls Ca2+ signals in excitable and non-excitable cells. However, there are no studies on TRPM4 in stem cells. In another study, …

The Feasibility, Acceptability, And Effectiveness Of A School-Based Motivational Interviewing Intervention For Adolescent Females, Vanessa Durand

Electronic Theses and Dissertations

Motivational Interviewing (MI) is an evidence-based therapeutic approach shown to elicit behavior change in adolescents engaged in risky behavior. MI is used to increase the individuals feeling of self-efficacy and outcome expectancy. Female adolescents engaged in substance use, sexual activity and identified as academically disengaged were provided an MI intervention in their alternative education setting. According to the Social Cognitive Theory, MI is well suited toward supporting individual behavior change. Results showed that MI is an acceptable intervention to at-risk adolescent females. However, feasibility considerations highlighted the implementation barriers present in this alternative high school as well as those in …

Expertise And Disbelief: Post-1945 American Attitudes Toward The Authority Of Knowledge, Terry Wagner

LSU Doctoral Dissertations

“You can’t beat brains,” said President John Kennedy of the intellectuals and technicians he assembled in his cabinet. Kennedy was perhaps the greatest political champion for the virtues of expertise. However, all over America during the 1960s and ‘70s, diverse groups voiced doubts about how much experts, such as social scientists, policy specialists, and others, actually improved life. This dissertation examines how movements on the political left and right, and spiritual ruptures such as the rise of ‘60s counterculture and of evangelicalism, spoke in different language to express a similar point: human mastery over the world is profoundly limited. Many …

Out-Of-School Sports Time And Children's Body Weight Status: Evidence From A Longitudinal Study, Juan Du, Qi Zhang, Michael Stallone

Economics Faculty Publications

We used data from the Child Development Supplement (CDS) of the Panel Study of Income Dynamics in 2002 and 2007 to examine the relationship between the specific sport time spent during weekdays or weekends and American children’s body mass index (BMI). Time spent on out-of-school sports was recorded on a randomly selected weekday and a weekend day. Sports were further categorized as formal (organized sports such as sports games or lessons) or casual (any unorganized sports such as sports time in the neighborhood). Child’s height and weight were measured in person by interviewers. Body mass index was used to measure …

A Tale Of Two Cultures: A Qualitative Narrative Of Nigerian Immigrant Parenting In The United States, Chinwe Onwujuba

LSU Doctoral Dissertations

Current demographic estimates indicate that the foreign-born population makes up about 13% (40 million) of the total U.S. population. This number consists of immigrants from all over the world, with a larger majority originating from Latin America and Asia. Research in the area of immigrant adaptation is robust and compelling; however, it is replete with studies on immigrants from the cultural regions identified above, and not as much on other regions with relatively less numerical representation, specifically Africa. From this region, Nigerian individuals and families make up a larger portion of this immigrant group. This study employs a qualitative research …

Scanning Probe Investigations Of Nanopatterned And Thermo-Responsive Polypeptoids And The Design Of A Sample Stage For Force Modulation Microscopy, Lu Lu

LSU Doctoral Dissertations

Protocols for patterning nanostructures of polymers were developed to enable scanning probe microscopy (SPM) studies of surface properties at the molecular level. A chemically selective surface for patterning polymers was generated by combining particle lithography with organosilane immersion. Poly(N-allyl glycine), a biocompatible and backbone degradable polypeptoid, was grown on Si(111) at confined amine sites using surface-initiated polymerization (also known as the “graft from” approach). A thermo-responsive random copolypeptoid, poly[(N-ethyl glycine)32-r-(N-butyl glycine17)], was pre-synthesized and attached onto a patterned organosilane surface using a thiol-ene click reaction (“graft to” approach). The phase transitions of the copolypeptoid nanostructures in an aqueous environment was …

The Response Of Gossypium Spp. To Biotic And Abiotic Stresses In Louisiana And The Modeling Of Yarn Performance, Bikash Bhandari

LSU Doctoral Dissertations

Developing improved cotton cultivars depends on how cotton cultivars perform the best when under stresses. Reniform nematode is a major plant pathogen, causing 4-6% yield loss in southern United States. A variation in reproduction and pathogenicity across reniform isolates collected from Louisiana on susceptible cotton was reported. This study was conducted to determine the response of resistant/tolerant cotton genotypes to multiple reniform isolates by inoculating 10,000 juveniles into seven days old seedlings. Across genotypes, the Evan and Avoyelles isolates had significantly higher vermiform nematodes (33,793 and 27,800/250 g soil, respectively) than other isolates. Across isolates, the number of juveniles on …

A Comparative Case Study: An Examination Of How Literature Assists Children Experiencing A Trauma, Michelle Clare Benoit

LSU Doctoral Dissertations

This case study, with four elementary school students as participants, examined the use of books and bibliotherapy when experiencing a traumatic incident. Utilizing fiction books, I explored how literature could be a powerful tool for overcoming life-altering events and circumstances, such as losing a pet, going through a divorce, or dealing with a grandparent who is suffering from Alzheimer's, with a bully in school, or the death of a loved one. Bibliotherapy could also be effective when used with individuals that stutter, children with dyslexia, and children coping with death or a parental mental illness. For this study, the data …

Cellulose Nanofibers From Energycane Bagasse And Their Applications In Core-Shell Structured Hydrogels, Yiying Yue

LSU Doctoral Dissertations

Cellulose fibers (Cellulose I, cellulose II and cellulose I/II Hybrid fibers) were successfully extracted from energycane bagasse by using a combined NaOH and NaClO2 treatment. After the delignification process, most lignin and hemicellulose were removed with a 27.4wt% yield of cellulose fibers, and the mean diameter of cellulose fibers decreased from 137±46 (raw fiber bundles) to 12±5μm (unpacked fibers). The raw bagasse fibers showed a three-step pyrolysis process, while isolated cellulose fibers had a one-step pyrolysis process. NaClO2 treatment caused the reduction of cellulose thermal stability due to its acting on lignin and cellulose. With 10h NaOH treatment, the ribbon …

La Grad Act’S Effects On Developmental Faculty: A Case Study, Patricia Kuhlman Van Brunt

LSU Doctoral Dissertations

Over the past 50 years, state legislatures have placed mandates on higher education institutions to lower attrition, thereby increasing student retention and completion. This study investigated and sought to understand the relationship between the Louisiana Granting Resources and Autonomy for Diplomas Act, or the LA GRAD Act (2010), and developmental education. More specifically, it focused on the perceptions of the mandate held by developmental education faculty who are employed at a public, urban Louisiana community college. This study utilized the four-framework approach by Bolman and Deal (2013) to decipher how developmental classrooms, academic departments, and a higher education institution as …

From Their Own Voices: The Lived Experiences Of African Americans Exposed To Jim Crow, Janelle R. Carter

Electronic Theses and Dissertations

Researchers have become increasingly interested in the impact of racism on African Americans; however, because interactions involving racism are highly subjective, it can be difficult to assert the presence of trauma in a social science context. Thus, whereas literature regarding the effects of racism is abundant, few studies have explored the effects of being exposed to the laws of the "Jim Crow" era. This study sought to illuminate the lived experiences of African Americans who were exposed to the racial caste system known as Jim Crow. This inquiry looked at transgenerational trauma, exploring exposure to decades of legal discrimination, while …

Beyond Batterers: A Primary Prevention And Adult Learning Approach To Engage Well-Meaning Men To Prevent Violence Against Women, Lorett Sturgill Swank

LSU Doctoral Dissertations

This purpose of this research is to examine the critical issue of intimate partner violence and to explore a how non-battering “well-meaning men” can help to end this violence against women. Domestic violence has been primarily considered a women’s issue, and current efforts to prevent this violence have been led mostly by women. In spite of these efforts, violence against women still persists and “well-meaning men” have not been part of a proactive solution. This growing movement to engage men in preventing violence against women, empowers men to learn about and identify the issues that support a culture that tolerates …

Genomes Of Three Arsenic Metabolizing Bacteria, Xue Chen

Electronic Theses and Dissertations

Although arsenic is toxic to most living cells, many microbes live in environments with high concentrations of arsenic. In addition to being resistant to arsenic, some actively couple arsenic oxidation/reduction reactions to respiration gaining energy in the process. Following a current review of the literature, the genomes of the three such bacteria, one arsenite oxidizer, Alkalilimnicola ehrlichii MLHE-1, and two arsenate reducers, Alkaliphilus oremlandii OhILAs, and Bacillus selenitireducens MLS-10 are presented. The genome of Alkalilimnicola ehrlichii MLHE-1 consists of 3,275,944 bp with a 67.53% GC content; the genome of Alkaliphilus oremlandii OhILAs consists of 3,123,558 bp with a 36.26% GC …

A Quantitative Study Using Constructist Learning Activities To Connect Biology Concepts To Local Environmental Issues In A Non-Major Introductory College Biology Course, Michaelyn Broussard

LSU Doctoral Dissertations

Among the general population, there has continued to be a struggle to improve environmental literacy with the knowledge, attitude, and awareness of basic environmental issues locally and nationally. Despite efforts through many formal and informal programs, the result nationally has indicated little to no understanding of basic environmental issues (Coyle, 2005). Many educators such as Sobel (1996, 2004) and Louv (2005) have documented the lack of positive outdoor experiences or environmental behaviors. The purpose of this study was to incorporate local environmental examples through constructivist learning techniques within a general biology non-major course to promote an increase in environmental literacy …

School of Public Service Faculty Publications

Non-profit organizations are actively using social media platforms as a way to deliver information to end users, yet little is known of the internal processes these organizations follow to implement this tool. We present a case study of one non-profit organization, Blue Star Families, Inc., that is actively engaged in advocacy and civic engagement. We offer a new model to explore non-profit organizations' use of social media platforms by building on previous models and frameworks developed to explore the use of social media in the public, private, and non-profit sectors.

Macrophage Cox-2 As A Target For Imaging And Therapy Of Inflammatory Diseases Using Theranostic Nanoemulsions, Sravan Kumar Patel

Electronic Theses and Dissertations

Personalized medicine can be an approach to address the unsatisfactory treatment outcomes in inflammatory conditions such as cancer, arthritis, and cardiovascular diseases. A common feature of chronic diseases is the infiltration of pro-inflammatory macrophages at the disease loci. Infiltrating macrophages have been previously utilized for disease diagnosis. These features suggest that macrophages can be broadly applicable targets for simultaneous therapy and diagnosis. Cyclooxygenase-2 (COX-2), an enzyme involved in the biosynthesis of a lipid inflammatory mediator, prostaglandin E2 (PGE2), is over expressed in macrophages infiltrating the pathological site. Inhibition of PGE2 leads to reduced inflammation, pain and macrophage infiltration. To utilize …

Copyright's Technological Interdependencies, Clark D. Asay

Faculty Scholarship

Copyright was initially conceptualized as a means to free creative parties from dependency on public and private patrons such as monarchs, churches, and well-to-do private citizens. By achieving independence for creative parties, the theory ran, copyright led to greater production of a more diverse set of creative works.

But this lingering conception of copyright is both inaccurate and harmful. It is inaccurate because, in today’s world, creative parties are increasingly dependent upon “Technological Patronage” from the likes of Google, Amazon, Apple, and others. Thus, rather than being alternatives or adversaries, copyright and Technological Patronage are increasingly interdependent in facilitating both …

Reintroducing Invention To Innovation: Investigating The White Space In Marketing Innovation, Mandy E. Dlugos

Electronic Theses and Dissertations

This project investigates the relationship between rhetorical theory and marketing innovation as practiced in the consumer packaged goods industry. Marketing innovation, or the development of new products, product features (including packaging and messaging), and services, is a process-heavy practice often resulting in incremental or novelty innovations that do not drive long-term marketplace success for consumer packaged goods companies.

The history of innovation in consumer packaged goods companies is generally rooted in new-to-world innovations that meet a defined consumer audience's need or fill a gap in the marketplace. Over the past seven decades, this included developing packaged products that helped people …
