Humanitarian Watchdogs: The Impact Of Humanitarian Aid On State Behavior, Kevin David Bradley

LSU Doctoral Dissertations

Does the delivery of humanitarian aid outside the control of the state increase repressive practices by the government and harm the population? Concerns over the unintended negative impacts of humanitarian aid continues to drive research and spirited debate by scholars, policy makers, and practitioners. Although several contend humanitarians serve as “watchdogs” and constrain repression by their presence in a country, whether they do this, the methods employed, and the scope of impact has not been theoretically or empirically addressed. The watchdog theory proposes that the presence of humanitarian international non-governmental organizations (INGOs) generates information about the disaster, the actions of …

New Features Of Laboratory-Generated Epfrs From 1,2-Dichlorobenzene (Dcb) And 2-Monochlorophenol (Mcp), Lavrent Khachatryan, Marwan Y. Rezk, Divine Nde, Farhana Hasan, Slawomir Lomnicki, Dorin Boldor, Robert Cook, Phillip Sprunger, Randall Hall, Stephania Cormier

Faculty Publications

The present research is primarily focused on investigating the characteristics of environmentally persistent free radicals (EPFRs) generated from commonly recognized aromatic precursors, namely, 1,2-dichlorobenzene (DCB) and 2-monochlorophenol (MCP), within controlled laboratory conditions at a temperature of 230 °C, termed as DCB230 and MCP230 EPFRs, respectively. An intriguing observation has emerged during the creation of EPFRs from MCP and DCB utilizing a catalyst 5% CuO/SiO2, which was prepared through various methods. A previously proposed mechanism, advanced by Dellinger and colleagues (a conventional model), postulated a positive correlation between the degree of hydroxylation on the catalyst’s surface (higher hydroxylated, HH and less …

Producing Digital Reflections Of Reality Through Intercultural Filmmaking And Multisensory Engagement, Trai Thomas

LSU Doctoral Dissertations

This thesis analyzes the author’s production of three intercultural, multisensory films situated in New Orleans, encompassing elements both narrative and documentary genres. Intercultural cinema exists in a setting where people of different cultural backgrounds live together in power-inflicted spaces of diaspora, colonialism, and cultural apartheid and the development of the story is centered around exoticism, fetishization, and fascination with the other (Marks 2007, 1). Multisensory media primarily engages through visual perception and auditory input, which create cultural knowledge stored as long-term memory files in the brain (Marks 2007).

Advancing Cr(Vi) Electroreduction: A Redox Mediator To Catalyze The Electrochemical Reduction Of Cr(Vi) In Water While Preventing Fouling Of Carbon Electrodes, Callie M. Stern, Malithi M. Abeythunga, Noémie Elgrishi

Faculty Publications

Hexavalent chromium is a contaminant of concern and is found in drinking water supplies. Electrochemical methods are well-suited to accomplish the reduction of toxic Cr(VI) to Cr(III). However, high overpotentials and plating of Cr(III) products on electrodes have stymied the development of efficacious purification methods. The Cr(VI) reduction reaction necessitates the transfer of multiple protons and electrons, which is accompanied by a high kinetic barrier. Following recent advances in the electrocatalytic energy storage community, we report that the use of [Fe(CN)6]^3- as a small molecular electrocatalyst not only diminishes the overpotential for Cr(VI) reduction on carbon electrodes by 0.575 …

Klebsiella Pneumoniae Deda Family Proteins Have Redundant Roles In Divalent Cation Homeostasis And Resistance To Phagocytosis, Vijay Tiwari, Amit Sharma, Reygan Braga, Emily Garcia, Ridhwana Appiah, Renee Fleeman, Basel H. Abuaita, Marianna Patrauchan, William T. Doerrler

Faculty Publications

The DedA superfamily is a highly conserved family of membrane proteins. Deletion of Escherichia coli yqjA and yghB, encoding related DedA family proteins, results in sensitivity to elevated temperature, antibiotics, and alkaline pH. The human pathogen Klebsiella pneumoniae possesses genes encoding DedA family proteins with >90% amino acid identity to E. coli YqjA and YghB. We hypothesized that the deletion of K. pneumoniae yqjA and yghB will impact its physiology and may reduce its virulence. The K. pneumoniae ΔyqjA ΔyghB mutant (strain VT101) displayed a growth defect at 42°C and alkaline pH sensitivity, not unlike its E. coli counterpart. However, …

Irrigation Of Sand-Based Creeping Bentgrass Putting Greens With Nanobubble-Oxygenated Water, Eric J. Deboer, Michael D. Richardson, John H. Mccalla

Faculty Publications

Cultural and environmental factors can place creeping bentgrass (Agrostis stolonifera) under extreme stress during the summer months. This stress, coupled with the growth adaptation of creeping bentgrass, can result in shallow, poorly rooted stands of turf. To enhance root zone oxygen and rooting of creeping bentgrass, golf courses use methods such as core and solid-tine aerification, and sand topdressing. An additional method of delivering oxygen to the soil could be irrigation with nanobubble-oxygenated water. The properties of nanobubbles (NBs) allow for high gas dissolution rates in water. Irrigating with NB-oxygenated water sources may promote increased rooting of creeping bentgrass putting …

Against Conflict, Against Occupation: Protest Songs In India And Kashmir, Mridula Sharma

Comparative Woman

The establishment of All India Progressive Writers’ Association in colonial India encouraged artists to articulate and examine social realities. Literary-cultural productions, particularly popular songs in Hindi films, in independent India continued to remain preoccupied with social conflicts such as religious bigotry and communalism. Sahir Ludhianvi’s “Yeh Duniya Agar Mil Bhi Jaye” (trans. “What can one gain, even if one gains this world?,” 1958 ) and “Yeh Kiska Lahu Hai, Kaun Mara” (trans. “Whose Blood Has Spilled? Who Died?,” 1961) are early examples of a lasting tide of pessimism owing to communal violence during the 1947 India-Pakistan …

In Search Of The Armorial Aesthetic: The Counter-Reform Of Ariano Suassuna And The Compositional Techniques In Clovis Pereira’S Suite Macambira, Wagner De Oliveira Duarte

LSU Doctoral Dissertations

Throughout the first half of the twentieth century, in the wake of the Week of Modern Art in São Paulo in 1922, Brazil grappled with defining its national identity, distinct from European influences. While eminent figures such as Villa-Lobos, Camargo Guarnieri, and Francisco Mignone provided foundational narratives in this quest, the Armorial movement emerged as a unique and emblematic response to these nationalistic aspirations.

Originating from the creative vision of Ariano Suassuna, the Armorial movement, though often perceived as a regional initiative, epitomized a broader endeavor to represent Brazil's diverse cultural tapestry. Central to understanding this movement is the work …

Key findings emerged through four themes …

Death, Dreaming, And Diaspora: Achieving Orientation Through Afro-Spirituality, Liz Johnston, Jaime Elizabeth Johnston

LSU Doctoral Dissertations

Enslavement, colonization, and the systems that uphold racial injustice were and still are a series of new, unfathomable, and challenging experiences that prompt individuals within the diaspora to seek orientation. How does a human cope with centuries of attempts at the systematic destruction of their humanity, culture, and identity? How can they reclaim that identity, especially when so much of it seems lost? I address these questions by utilizing texts from the expansive body of work regarding ethnographic-historical-religious studies on Afro-spiritual practices to better analyze instances in literature in the ongoing practice of diasporic orientation. In this project, I argue …

Time, Place, & Purpose: The Performance Of Creole Identity In Louisiana, Rachel N. Aker

LSU Doctoral Dissertations

Though much of the early development of Louisiana Creole culture can be found in New Orleans, the culture spread and continued to grow throughout the rest of South Louisiana in both similar and different ways. Expanding beyond Joseph Roach’s treatment of Creole cultural performances in New Orleans in Cities of the Dead (1996) and journeying across land and water, this project identifies more Creole cultural performance as they emerge across place and time. I present Louisiana and the Gulf South as a kind of inland archipelago, with the currents of culture-creation moving in and around distinct community enclaves. The flow …

Madness As Response To Inherent Cultural Conflicts In Anglophone Fiction From 1700 To 2020, Anna Klambauer

Comparative Woman

Madness in literature has a long and colourful history. While its representation varies significantly in different literary periods, madness is nonetheless a consistent theme responding to inherent conflicts of civilisation. Thus, in the eighteenth-century novel, madness is subdued and forced to express itself in the language of rationality, while in the nineteenth century the theme becomes increasingly subversive. In the form of the madwoman trope (Gilbert and Gubar 1979), madness is simultaneously a reaction to restrictive patriarchal norms, and a frame in which the gender conflicts of the time can be safely and effectively played out. In the twentieth century, …

The COVID-19 pandemic impacted personal and professional life. For academics, research, teaching, and service tasks were upended and we all had to navigate the altered landscape. However, some individuals faced a disproportionate burden, particularly academics with minoritized identities or those who were early career, were caregivers, or had intersecting identities. As comparative endocrinologists, we determine how aspects of individual and species-level variation influence response to, recovery from, and resilience in the face of stressors. Here, we flip that framework and apply an integrative biological lens to the impact of the COVID-19 chronic stressor on our endocrine community. We address how …

Faculty Publications

Background: African American or Black (hereafter referred to as Black) adults who use cannabis use it more frequently and are more likely to meet criteria for cannabis use disorder (CUD) than both White and Hispanic or Latin individuals. Black adults may be more apt to use cannabis to cope with distress, which constitutes a false safety behavior (FSB; a behavior designed to reduce psychological distress in the short term). Although FSB engagement can perpetuate the cycle of high rates of CUD among Black individuals, limited work has applied an FSB elimination treatment approach to Black adults with CUD, and no …

Rationale And Challenges For A New Instrument For Remote Measurement Of Negative Symptoms, David Gordon Daniel, Alex S. Cohen, Philip D. Harvey, Dawn I. Velligan, William Z. Potter, William P. Horan, Raeanne C. Moore, Stephen R. Marder

Faculty Publications

There is a broad consensus that the commonly used clinician-administered rating scales for assessment of negative symptoms share significant limitations, including (1) reliance upon accurate self-report and recall from the patient and caregiver; (2) potential for sampling bias and thus being unrepresentative of daily-life experiences; (3) subjectivity of the symptom scoring process and limited sensitivity to change. These limitations led a work group from the International Society of CNS Clinical Trials and Methodology (ISCTM) to initiate the development of a multimodal negative symptom instrument. Experts from academia and industry reviewed the current methods of assessing the domains of negative symptoms …

Introduction: Metabolic flexibility is the ability of a system to switch between metabolic substrates. Human and murine skeletal muscle tissues and cells with decreased activity of the regulatory RNA-binding protein, human antigen R (HuR), have decreased capacity for fat oxidation, and thus decreased metabolic flexibility. In this study, we aimed to assess the preference for carbohydrates in mice lacking HuR in skeletal muscle. Methods: Experiments were performed on weight-matched control and HuR knockout mice of both sexes. Palmitate and pyruvate oxidation were performed in mouse muscle following the release of 14CO2. In vivo glucose and lipid uptake were assayed in …

The desire to live in a healthy “green” environment is becoming increasingly important to global populations. The term “green” is overused, confusing, and inconsistently used among and between consumers, corporate enterprises, environmental groups, government entities, and other segments globally. Research studies suggest that defining and applying the term “green” to behaviors and decision-making is constantly changing, further complicating the study of corporate and consumer environmental responsibility. In this study, we focus on the consumer. Not all consumers behave the same or have the same beliefs and perceptions regarding what is environmentally “green.” As such, we segmented consumers in Slovakia into …
