The Effect Of A Gratitude Intervention On Acute Pain Toleration, Cynthia Ware

Honors College Theses

Gratitude interventions are emerging as a method to improve physical health outcomes; however, gratitude’s effect on pain perception and the autonomic response is understudied. Recent research suggests the perigenual anterior cingulate cortex is activated in gratitude interventions and is also involved in the perception of pain and the activation of the sympathetic nervous system. In this study, we investigated the effect of state gratitude induction on pain through the use of the cold pressor method. We found that although there were no significant differences in self-reported unpleasantness, participants in the gratitude condition reported a higher intensity of pain. Nevertheless, participants …

Exploring The Interactive, Linguistic, And Conceptual Dimensions Of Parent Input And Their Role In Children's Pragmatic Development, Nickolas T. Day

LSU Master's Theses

The development of children’s pragmatic language, which can be defined as conversational competence in social contexts, has been attributed to variation in the language they hear in their environment. When studying the impact language input has on pragmatic development, it is important for clinicians and linguists to measure both the quantity and quality of this language input. Measures of quality, however, are much more relevant when studying the development of pragmatic language, as discussed in Zhang (2020) and Hirsh-Pasek et al. (2015). Rowe and Snow (2016) discussed three dimensions of language quality: interactive, linguistic and conceptual. There is a current …

Identifying Key Language Research Priorities In Autistic Children According To Parents, Taylor Hale

LSU Master's Theses

The lack of involvement of the autistic community and its stakeholders in autism research has led to a call to action. At present, autism researchers have limited knowledge about stakeholders’ priorities for research. The current study aimed to bridge the disconnect between the extant autism research and the recent neurodiversity movement by surveying key stakeholders – parents of autistic children – on their perspectives on autism research that focuses on language. Twenty-six parents of autistic children completed an online survey on their views on autism language research with an option to participate in a follow-up interview. Six parents participated in …

Gulf Sturgeon Mesohabitat Use And Movement In The Lower Pearl River Louisiana-Mississippi, Amanda Popovich

LSU Master's Theses

After spring migrations to natal rivers Gulf Sturgeon Acipenser oxyrinchus desotoi reside in freshwater holding areas prior to fall emigrations to nearby estuaries. Limited published information on the physical habitat characteristics of these holding areas is available, especially for juvenile fish in the western portion of the Gulf Sturgeon’s distribution. To further investigate freshwater occupancy and movement patterns, 32 acoustic receivers were deployed from late April to October of 2021 and 2022 in 1600-m reaches distributed throughout the lower Pearl River, Louisiana-Mississippi, the westernmost river within their distribution. Generalized linear mixed models and multi-state models were used to determine what …

Plants Detect And Adapt, But Do Not Feel, Paul C. Struik

Animal Sentience

Plant sentience is a hot topic in scientific and popular media. There are moral reasons to respect both the service of plants to humanity and their natural integrity as creatures playing their own significant role in a complex ecosystem. However, to infer that plants have certain cognitive capacities that are present also in certain human and nonhuman animals calls for scientific rigor beyond mere analogy. The unique capacities of plants identified by Segundo-Ortin & Calvo are not necessarily linked to sentience. Nor is it likely that sentience is an evolutionary trait that is present to some extent in all living …

Overview Of The Application Of Remote Sensing In Effective Monitoring Of Water Quality Parameters, Godson Ebenezer Adjovu, Haroon Stephen, David James, Sajjad Ahmad

Civil and Environmental Engineering and Construction Faculty Research

This study provides an overview of the techniques, shortcomings, and strengths of remote sensing (RS) applications in the effective retrieval and monitoring of water quality parameters (WQPs) such as chlorophyll-a concentration, turbidity, total suspended solids, colored dissolved organic matter, total dissolved solids among others. To be effectively retrieved by RS, these WQPs are categorized as optically active or inactive based on their influence on the optical characteristics measured by RS sensors. RS applications offer the opportunity for decisionmakers to quantify and monitor WQPs on a spatiotemporal scale effectively. The use of RS for water quality monitoring has been explored in …

The Possibility Of Relationships With Others, Joshua Severud

LSU Master's Theses

Levinas offers a rich philosophical insight into the kind of responsibility and ethics that we must have for the Other. This involves a certain conception of what it means to be hospitable which turns out to be impossible. In order to talk about how this impossible relationship can occur, I use Heidegger’s description of the existential Being-with structure and Derrida’s conception of the event in order to make sense of how this Levinasian relationship can possibly exist in spite of—or thanks to—its impossibility.

Examining The Factors That Contribute To Pro-Environmental Behaviour Between Rural And Urban Populations, Alan Smith, Jade Sheasby

School of Geography, Earth and Environmental Sciences

Factors that influence pro-environmental behaviour in individuals can be examined to assess the influence of a single element or combination of elements. In this study, eight factors were investigated for their influence on pro-environmental behaviour: environmental knowledge, environmental attitude, the influence of others, environmental responsibility, age, qualification level, employment status and locality (rural or urban). These factors were established from behavioural theory in the field of psychology, specifically the theory of planned behaviour. Data were collected via an online questionnaire, for which the participants were scored on answers to pro-environmental behaviour questions, which, in turn, were correlated against established influences …

In A Nutshell, Marieann C. Raguso

Digressions: Literary & Art Journal

"As a woman veteran who was exposed to combat, death, violence, sexual assault, and other traumas during my time in service and after service with the VA, I felt I had something to say but had no idea where to begin. Upon attending college, I began to take poetry courses and fell in love with the art form. Not only that, but poetry allows me to be resilient against these traumatic, sometimes intrusive stressors and functions as a positive coping mechanism. So when I write, I write with my emotional intensity and always in my distinct voice."

Effect Of Furosemide Administration On Plasma Analytes And Urine Enzyme Excretion In Two Reptilian Species, Kathryn Metcalf

LSU Master's Theses

Renal disease is a common ailment of captive reptiles that is often closely linked to chronic, subclinical states of dehydration. Currently, the diagnosis of renal disease in reptiles is poorly characterized and often relies on invasive diagnostic techniques (e.g., renal biopsy) for definitive diagnosis. A potential outlet for the further characterization of renal dysfunction in reptiles is the induction of dehydration by furosemide therapy. Furosemide is a loop diuretic that is commonly used in mammalian patients for the treatment of congestive heart failure. The utility of furosemide in reptiles is poorly characterized, however, both experimental and clinical utility of this …

Koonja's Death From Neville's Perspective, Michelle L. Gorodisky

Digressions: Literary & Art Journal

In Grace Cho's memoir Tastes Like War, she states that her brother, Neville, was the one who had found her mother when she died. This scene will take place under Neville’s point of view, because his thoughts about their family’s situation are not examined very thoroughly throughout the memoir. Considering Cho and Neville’s starkly contrasting opinions about their family experiences, I thought it would be interesting to try reading this scene from Neville’s perspective."

Questions About Sentience Are Not Scientific But Cultural, Yoram Gutfreund

Animal Sentience

Abstract: The findings of complex cognitive-like behaviours in plants are surprising and exciting. However, they do not provide a scientific reason for ascribing sentience to plants. The target article, in trying to provide evidence for sentience in plants, exposes the weakness of the science of animal consciousness in general. In this commentary, I try to explain why the scientific method is incapable of resolving the question of which organisms or systems are sentient.

Persistence Of Dna From Biocontained Genetically Engineered Microbes, Wentao Dai

McKelvey School of Engineering Graduate Student Theses & Dissertations

The utilization of genetically engineered microbes in environmental systems requires effective biocontainment mechanisms to ensure their safe operation. CRISPR-based kill switches are a promising solution, inducing cell death through site-specific DNA cleavage under specific environmental conditions. In this study, we aimed to assess the impact of CRISPR-based kill switches on the abundance and persistence of bacterial DNA. Our results revealed that while CRISPR-based kill switches were capable of achieving high reductions in viable Escherichia coli Nissle 1917 (EcN); the DNA largely remained intact. This was observed in two strains of EcN: one enabled with multi-locus genome cleavage, and the other …

A Study Of The Social Media Perceptions And Guest Satisfaction Concerning Recent Changes Related To The Genie+ System In The Walt Disney World Theme Parks, Kylie N. Bennett

Honors College Theses

This study examines the social media perceptions and guest satisfaction rates concerning recent changes related to the introduction of the Genie+ system in the Walt Disney World theme parks. Social media has allowed the public to share these opinions about changes in the Walt Disney World theme parks, but it is not known how these opinions compare to the lived guest experience. It is said that with the introduction of a paid standby queue bypass system the Walt Disney Company is making that aspect of its parks less accessible than in the past (Austin, 2022). This study uses a mixed …

Pattern Dynamics And Stochasticity Of The Brain Rhythms, Clarissa Hoffman, Jingheng Cheng, Daoyun Ji, Yuri Dabaghian

Faculty, Staff and Student Publications

Our current understanding of brain rhythms is based on quantifying their instantaneous or time-averaged characteristics. What remains unexplored is the actual structure of the waves-their shapes and patterns over finite timescales. Here, we study brain wave patterning in different physiological contexts using two independent approaches: The first is based on quantifying stochasticity relative to the underlying mean behavior, and the second assesses "orderliness" of the waves' features. The corresponding measures capture the waves' characteristics and abnormal behaviors, such as atypical periodicity or excessive clustering, and demonstrate coupling between the patterns' dynamics and the animal's location, speed, and acceleration. Specifically, we …

Statins Enhance The Efficacy Of Her2-Targeting Radioligand Therapy In Drug-Resistant Gastric Cancers, Yi Rao, Zachary Samuels, Lukas M Carter, Sebastien Monette, Sandeep Surendra Panikar, Patricia M R Pereira, Jason S Lewis

2020-Current year OA Pubs

Human epidermal growth factor receptor 2 (HER2) is overexpressed in various cancer types. HER2-targeting trastuzumab plus chemotherapy is used as first-line therapy for HER2-positive recurrent or primary metastatic gastric cancer, but intrinsic and acquired trastuzumab resistance inevitably develop over time. To overcome gastric cancer resistance to HER2-targeted therapies, we have conjugated trastuzumab with a beta-emitting therapeutic isotope, lutetium-177, to deliver radiation locally to gastric tumors with minimal toxicity. Because trastuzumab-based targeted radioligand therapy (RLT) requires only the extramembrane domain binding of membrane-bound HER2 receptors, HER2-targeting RLT can bypass any resistance mechanisms that occur downstream of HER2 binding. Leveraging our previous …

Cd73-Dependent Adenosine Signaling Through Adora2b Drives Immunosuppression In Ductal Pancreatic Cancer, Erika Y Faraoni, Kanchan Singh, Vidhi Chandra, Olivereen Le Roux, Yulin Dai, Ismet Sahin, Baylee J O'Brien, Lincoln N Strickland, Le Li, Emily Vucic, Amanda N Warner, Melissa Pruski, Trent Clark, George Van Buren, Nirav C Thosani, John S Bynon, Curtis J Wray, Dafna Bar-Sagi, Kyle L Poulsen, Lana A Vornik, Michelle I Savage, Shizuko Sei, Altaf Mohammed, Zhongming Zhao, Powel H Brown, Tingting Mills, Holger K Eltzschig, Florencia Mcallister, Jennifer M Bailey-Lundberg

The microenvironment that surrounds pancreatic ductal adenocarcinoma (PDAC) is profoundly desmoplastic and immunosuppressive. Understanding triggers of immunosuppression during the process of pancreatic tumorigenesis would aid in establishing targets for effective prevention and therapy. Here, we interrogated differential molecular mechanisms dependent on cell of origin and subtype that promote immunosuppression during PDAC initiation and in established tumors. Transcriptomic analysis of cell-of-origin-dependent epithelial gene signatures revealed that Nt5e/CD73, a cell-surface enzyme required for extracellular adenosine generation, is one of the top 10% of genes overexpressed in murine tumors arising from the ductal pancreatic epithelium as opposed to those rising from acinar cells. …

Swi/Snf Blockade Disrupts Pu1-Directed Enhancer Programs In Normal Hematopoietic Cells And Acute Myeloid Leukemia, Courtney Chambers, Katerina Cermakova, Yuen San Chan, Kristen Kurtz, Katharina Wohlan, Andrew Henry Lewis, Christiana Wang, Anh Pham, Milan Dejmek, Michal Sala, Mario Loeza Cabrera, Rogelio Aguilar, Radim Nencka, H Daniel Lacorazza, Rachel E Rau, H Courtney Hodges

UNLABELLED: In acute myeloid leukemia (AML), SWI/SNF chromatin remodeling complexes sustain leukemic identity by driving high levels of MYC. Previous studies have implicated the hematopoietic transcription factor PU.1 (SPI1) as an important target of SWI/SNF inhibition, but PU.1 is widely regarded to have pioneer-like activity. As a result, many questions have remained regarding the interplay between PU.1 and SWI/SNF in AML as well as normal hematopoiesis. Here we found that PU.1 binds to most of its targets in a SWI/SNF-independent manner and recruits SWI/SNF to promote accessibility for other AML core regulatory factors, including RUNX1, LMO2, and MEIS1. SWI/SNF inhibition …

Temperament & Character Account For Brain Functional Connectivity At Rest: A Diathesis-Stress Model Of Functional Dysregulation In Psychosis, Igor Zwir, Javier Arnedo, Alberto Mesa, Coral Del Val, Gabriel A. De Erausquin, C. Robert Cloninger

School of Medicine Publications

The human brain’s resting-state functional connectivity (rsFC) provides stable trait-like measures of differences in the perceptual, cognitive, emotional, and social functioning of individuals. The rsFC of the prefrontal cortex is hypothesized to mediate a person’s rational self-government, as is also measured by personality, so we tested whether its connectivity networks account for vulnerability to psychosis and related personality configurations. Young adults were recruited as outpatients or controls from the same communities around psychiatric clinics. Healthy controls (n = 30) and clinically stable outpatients with bipolar disorder (n = 35) or schizophrenia (n = 27) were diagnosed by …

Biodiversity Of Forage Fishes In The Lower Laguna Madre, Southernmost Texas, David Camarillo Jr., Elizabeth Mogus Garcia, Carlos E. Cintra-Buenrostro

School of Earth, Environmental, & Marine Sciences Faculty Publications

Coastal estuarine ecosystems serve as nursery habitats for many commercially and recreationally important fishes. Biodiversity is a structural indicator and has been used as a metric for conservation and management. In the hypersaline Lower Laguna Madre of Texas, a variety of organisms makes their living in and around the dominant seagrass vegetation. This study provides a general assessment of forage fishes biodiversity collected seasonally with bag seines in two sites: Holly Beach (HB) and South Bay (SB) within the most southern Texas bay system as part of a broader study on fish biology. A total of 15,880 fishes representing 32 …

School of Biological and Marine Sciences

The South Mid Atlantic Ridge comprises three main oceanic islands in the equatorial and tropical portions of the Atlantic Ocean. These islands are isolated from each other and equidistant from both the continental margins of South America and Africa, sharing common patterns but with different types of human use and pressures. Moreover, the areas beyond national jurisdiction between those islands are visited and exploited by distant fishing fleets and include large areas of shipping activity for commodities. Here, a pioneering integrated ecosystem assessment (IEA) process is constructed for the region among Saint Peter and Saint Paul’s Archipelago (Brazil), Saint Helena …
