Factors Influencing Consumers’ Willingness-To-Try Seafood Byproducts, Silvia Murillo, Ryan Ardoin, Witoon Prinyawiwatkul

Faculty Publications

With increasing global demand for seafood, seafood byproducts (SB) utilization can contribute to a more sustainable food supply chain through waste-to-value food product development. However, consumer perceptions of SB (e.g., fish skin and bones) are underexplored. Therefore, this study aims to evaluate some factors influencing consumers’ willingness-to-try seafood byproducts. An online survey was conducted in the USA regarding intervention of SB informational cues with N = 904 adult seafood consumers internationally. The proportion of consumers willing to try SB increased significantly (McNemar’s test, α = 0.05) from 47% to 68% after SB safety and health claims had been presented in …

Temporal Features Of Concepts Are Grounded In Time Perception Neural Networks: An Eeg Study, Karim Johari, Vicky T. Lai, Nicholas Riccardi, Rutvik H. Desai

Faculty Publications

Experimental evidence suggests that modality-specific concept features such as action, motion, and sound partially rely on corresponding action/perception neural networks in the human brain. Little is known, however, about time-related features of concepts. We examined whether temporal features of concepts recruit networks that subserve time perception in the brain in an EEG study using event and object nouns. Results showed significantly larger ERPs for event duration vs object size judgments over right parietal electrodes, a region associated with temporal processing. Additionally, alpha/beta (10–15 Hz) neural oscillation showed a stronger desynchronization for event duration compared to object size in the right …

Explanation Needed: Understanding The Low Graduation Rates Of Spanish-Speaking English Learners In Southeastern Louisiana, Alice I. Garcia

LSU Doctoral Dissertations

This qualitative research study used the case study method of one-on-one interviews to collect and examine the experiences of former English learners (ELs) who were unable to finish high school in southeastern Louisiana. This study aimed to identify specific factors that, using Everett Lee’s theory, pushed or pulled these ELs from school and affected their ability to graduate. The push factors that were identified included language, inadequate support, academic performance, discrimination, and lack of connection with school and culture. Pull factors that were identified included lack of prior education, immigration, poverty, pregnancy, being far from family, financially supporting family, and …

Reverberations Of Boarding School Trauma In Upstate New York, Grace A. Miller

Comparative Woman

The legacy of boarding schools in Upstate New York is one that non-Natives seem to have forgotten. This historical amnesia compounds other acts of genocide, including cultural genocide, of the Haudenosaunee people throughout US history. Established in 1855 at the Cattaraugus Reservation (Seneca), the Thomas Indian School would serve as an institution of forced assimilation and displacement, much like the other Native American boarding schools. While the larger US population has grown to forget these schools' existence, the shadowed legacy of institutions, like the Thomas Indian School, Haskell, and Carlisle Indian Industrial School, the rippling effects of these schools’ practices …

Magpies, Bridge And Goddess: Unearthing The Hidden Symbols And Rediscovering The Lost Goddess In Chinese Qiqiao Festival, Juan Wu

Comparative Woman

The Qiqiao Festival, also known as the Qixi Festival, or Chinese valentine’s day, is a festival celebrating the annual meeting of the Cowherd and Weaver Maid in mythology. The most influential version focuses on the romance or love theme; however, it ignores its underlying historical context, gender tension and mythical belief. This paper takes the texts, rituals and materials related to the Qiqiao festival to investigate its origin and evolution. First, it takes the anthological case of the Qiqiao festival in Xihe county to explore its core image of the holy bridge and Goddess Qiao. Second, it traces the bridge …

Human Subthalamic Nucleus Neurons Differentially Encode Speech And Limb Movement, Karim Johari, Ryan M. Kelley, Kris Tjaden, Charity G. Patterson, Andrea H. Rohl, Joel I. Berger, Daniel M. Corcos, Jeremy D.W. Greenlee

Faculty Publications

Deep brain stimulation (DBS) of the subthalamic nucleus (STN), which consistently improves limb motor functions, shows mixed effects on speech functions in Parkinson’s disease (PD). One possible explanation for this discrepancy is that STN neurons may differentially encode speech and limb movement. However, this hypothesis has not yet been tested. We examined how STN is modulated by limb movement and speech by recording 69 single- and multi-unit neuronal clusters in 12 intraoperative PD patients. Our findings indicated: (1) diverse patterns of modulation in neuronal firing rates in STN for speech and limb movement; (2) a higher number of STN neurons …

How To Do The History Of Sexual Science, Benjamin Kahan, Greta Lafleur

Faculty Publications

This introduction maps the ways in which sexual scientific thought circulated during the fin de siècle, tracing the interconnections between and breaks in the global circuits of sexological thought and how this circuitry continues to structure sexuality in the present. In so doing, Kahan and LaFleur position their approach and that of the special issue as a whole within the larger field of sexology, placing it in more robust dialogue with sexuality studies and attending in particular to sexology's racial and imperial logics. They examine the ways in which racial science and colonial knowledge constitute sexual science as an amorphous …

Remote Assessment Of Negative Symptoms Of Schizophrenia, David G. Daniel, Alex S. Cohen, Dawn Velligan, Phillip D. Harvey, Larry Alphs, Michael Davidson, William Potter, Alan Kott, Nina Schooler, Christopher R. Brodie, Raeanne C. Moore, Pierre Lindenmeyer, Stephen R. Marder

Faculty Publications

In contrast to the validated scales for face-to-face assessment of negative symptoms, no widely accepted tools currently exist for remote monitoring of negative symptoms. Remote assessment of negative symptoms can be broadly divided into 3 categories: (1) remote administration of an existing negative-symptom scale by a clinician, in real time, using videoconference technology to communicate with the patient; (2) direct inference of negative symptoms through detection and analysis of the patient's voice, appearance, or activity by way of the patient's smartphone or other device; and (3) ecological momentary assessment, in which the patient self-reports their condition upon receipt of periodic …

Markossian, Jenna Nikolaides, Elisabeth Ramsey, Hale M. Thompson, Juan C. Rojas, Brihat Sharma, Dmitriy Dligach, Madeline K. Oguss, Richard S. Cooper, Majid Afshar

Faculty Publications

Background: Automated and data-driven methods for screening using natural language processing (NLP) and machine learning may replace resource-intensive manual approaches in the usual care of patients hospitalized with conditions related to unhealthy substance use. The rigorous evaluation of tools that use artificial intelligence (AI) is necessary to demonstrate effectiveness before system-wide implementation. An NLP tool to use routinely collected data in the electronic health record was previously validated for diagnostic accuracy in a retrospective study for screening unhealthy substance use. Our next step is a noninferiority design incorporated into a research protocol for clinical implementation with prospective evaluation of clinical …

Multidisciplinary Collaboration To Develop A Digital Health Solution For Early Detection Of Cognitive Decline In Primary Care, Robin C. Hilsabeck, Jeffrey N. Keller, Maya L. Henry, Paul Toprac, Paul Rathouz, Varshinee Sreekanth, Avery Largent, Joshua Chang, Jessy Li, Lokesh Pugalenthi, Thomas Parsons, Heather E. Cuevas, Suzanne Schmitz

Clinical Research Faculty Publications

Background: Developing digital healthcare solutions that facilitate rapid identification and effective management of patients with Alzheimer disease and related disorders (ADRD) is an area of intense study. A critical juncture for these efforts involves the early detection of cognitive decline. Because primary care providers (PCPs) are the first line of medical care, they are often the first to hear concerns about cognitive decline. However, under-diagnosis of ADRD in primary care settings is widely recognized, as are the many barriers to routine cognitive screening. While information about brief cognitive screening tools for detecting ADRD is plentiful, PCPs remain uncertain about which …

Spam Detection Using Machine Learning And Deep Learning, Olubodunde Agboola

LSU Doctoral Dissertations

Text messages are essential these days; however, spam texts have contributed negatively to the success of this communication mode. The compromised authenticity of such messages has given rise to several security breaches. Using spam messages, malicious links have been sent to either harm the system or obtain information detrimental to the user. Spam SMS messages as well as emails have been used as media for attacks such as masquerading and smishing ( a phishing attack through text messaging), and this has threatened both the user and service providers. Therefore, given the waves of attacks, the need to identify and remove …

Migration And Displacement In Twenty-First Century Magical Realist Fiction, Laura Duncan Fontenot

LSU Doctoral Dissertations

In “Migration and Displacement in Twenty-First Century Magical Realist Fiction” I discuss identity development and the search for belonging of displaced people within twenty-first century magical realist novels. In each instance, the characters undergo some form of change heralded by a magical moment or moments. The “magic” allows the authors to literalize underlying cultural tensions by physically altering some aspect of a character. The changes are not mere metaphors, they are literal, bodily transformations. The first stage of this process are magical thresholds that allow passage in space and time far beyond the conventions of reality. A magical threshold literalizes …

Multiscale Analysis Of Cancer Service Areas In The United States, Changzhen Wang, Tracy Onega, Fahui Wang

The purpose of delineating Cancer Service Areas (CSAs) is to define a reliable unit of analysis, more meaningful than geopolitical units such as states and counties, for examining geographic variations of the cancer care markets using geographic information systems (GIS). This study aims to provide a multiscale analysis of the U.S. cancer care markets based on the 2014–2015 Medicare claims of cancer-directed surgery, chemotherapy, and radiation. The CSAs are delineated by a scale-flexible network community detection algorithm automated in GIS so that the patient flows are maximized within CSAs and minimized between them. The multiscale CSAs include those comparable in …

Defining Change Beyond A Binary System: Measurement And Interpretation Of Degrees Of Dysphonia Severity In The Individual And Across Voice Disorders, Lindsey Ann Parker

LSU Doctoral Dissertations

Objective: The current study examined the sensitivity of voice outcome measures in discriminating cut-off thresholds between degrees of dysphonia severity, correlations to perceived dysphonia, and the impact of vocal task. Differences between cases of adductor spasmodic dysphonia, benign vocal fold polyps, and unilateral vocal fold paralysis were also explored.

Method: Auditory-perceptual judgments were performed by three raters for four diagnostic groups: Normal (n=14), AdSD (n=15), Polyp (n=15) and UVFP (n=15). Receiver operator characteristic area under the curve (AUC) analyses established screening and dysphonia severity (mild, moderate, severe) cut-off thresholds for auditory-perceptual visual analog scale (VAS) ratings and acoustic measures (f0_SD, …

Verb Diversities Of Children With And Without Developmental Language Disorder: A Study Of Language Samples, Caitlyn J. Kearns

LSU Master's Theses

Background: There have been numerous studies that have researched word learning in children with Developmental Language Disorder (DLD). These studies have found that children with DLD present with higher vocabulary deficits compared to their typically developing (TD) peers. Many of these studies’ results suggest that verb learning is the most difficult word type to comprehend in early language development for both TD children and children with DLD. This current study aims to examine verb use in children with and without DLD and to specifically examine their usage of GAP verbs. Methods: Participants included 36 children, 18 TD and 18 DLD …

The Effect Of Word-Learning Biases On Early Vocabulary Acquisition In Young Children On The Autism Spectrum, Claire C. Bourgeois

LSU Master's Theses

Background: Vocabulary composition and word-learning biases are closely interrelated in typical development. Such word-learning biases are influenced by perceptually and conceptually salient word features, including imageability, concreteness, iconicity, and attention to shape. Autistic children often have delayed language acquisition, but there is currently little research examining the underlying mechanisms autistic children use to acquire words. The current study aimed to examine the noun composition of autistic children across a range of vocabulary sizes by examining associations between expressive noun vocabulary size and imageability, iconicity, concreteness and evidence for the shape bias, and to examine whether these patterns differ from their …

Investigating The Theoretical Orientations Of Select Louisiana Preservice Teachers Regarding Teaching Reading: A Mixed-Methods Study, Megan Jenny

LSU Doctoral Dissertations

Teacher quality is one of the most significant factors contributing to student success, and Teacher Preparation Programs (TPPs) are traditionally responsible for teaching preservice teachers how to teach reading. Effective reading instruction is responsive, complex, and equitable. Acknowledgement of a disconnect between preparation programming and critical teacher knowledge for teachers of reading indicated a need for this exploratory mixed-methods study. The purpose of the current study, grounded by the theoretical framework of Sociocultural Theory, was to investigate what a select group of 21 preservice grades 1-3 elementary teachers were taught about teaching reading, preservice teachers’ theoretical orientations for teaching reading, …

This multiple case study examined the degree to which pre-service teachers were prepared to teach writing and how these skills were further developed in the beginning years of teaching to ensure students were receiving foundational literacy skills to be successful in both reading and writing. The setting for this study took place in an urban charter school and a suburban traditional public school in southeastern Louisiana. The participants for this study included two university instructors of teacher preparation programs who taught literacy methods courses. Also included were four K-2 classroom teachers, one kindergarten teacher, one second-grade teacher, and two first-grade …

Of Language And Thought: American Political Discourse, Normative Reason, And Essentially Contested Concepts, Riley Clare Valentine

LSU Doctoral Dissertations

This dissertation analyzes progressive liberalism and neoliberalism as forms of normative reason that redefine specific political concepts, which are central to American liberalism – equality, liberty, the role of the State, and the pursuit of happiness. I contend that language is an important expression of normative reason. Language is how political reason and the norms accompanying it are expressed. I move through Presidents Franklin Delano Roosevelt to Barack Obama, exploring shifts in language and interpretations of political concepts through progressive liberal and neoliberal forms of normative reason. I argue that a tension emerges between progressive liberalism and neoliberalism, and a …

Hd-Tdcs Of Primary And Higher-Order Motor Cortex Affects Action Word Processing, Karim Johari, Nicholas Riccardi, Svetlana Malyutina, Mirage Modi, Rutvik H. Desai

Faculty Publications

The contribution of action-perception systems of the brain to lexical semantics remains controversial. Here, we used high-definition transcranial direct current stimulation (HD-tDCS) in healthy adults to examine the role of primary (left hand motor area; HMA) and higher-order (left anterior inferior parietal lobe; aIPL) action areas in action-related word processing (action verbs and manipulable nouns) compared to non-action-related control words (non-action verbs and non-manipulable nouns). We investigated stimulation-related effects at three levels of semantic processing: subliminal, implicit, and explicit. Broadly, we found that stimulation of HMA and aIPL resulted in relative facilitation of action-related language processing compared to non-action. HMA …

Unsupervised Summarization Of Privacy Concerns In Mobile Application Reviews, Fahimeh Ebrahimi, Anas Mahmoud

Faculty Publications

The proliferation of mobile applications (app) over the past decade has imposed unprecedented challenges on end-users privacy. Apps constantly demand access to sensitive user information in exchange for more personalized services. These - mostly unjustifiable - data collection tactics have raised major privacy concerns among mobile app users. Such concerns are commonly expressed in mobile app reviews, however, they are typically overshadowed by more generic categories of user feedback, such as app reliability and usability. This makes extracting user privacy concerns manually, or even using automated tools, a challenging and time-consuming task. To address these challenges, in this paper, we …

Examination Of Autism Symptoms Across Ethnic Groups: Cross-Cultural Validation Of The Baby And Infant Screen For Children With Autism Traits (Biscuit), Esther Hong

LSU Doctoral Dissertations

Autism spectrum disorder (ASD) a neurodevelopmental disorder characterized by impairments in social communication and interaction and the presence of restricted and repetitive behaviors (American Psychiatric Association, 2013). Variations in prevalence across different racial and ethnic groups have been reported. Though the reason for these variations is unclear, racial and ethnic disparities in access to early screening services, cultural differences in ASD presentation, and the use of culturally insensitive screening tools appear to contribute to disparities in ASD diagnosis. Thus, cultural validation studies of ASD screening tools are needed to investigate the cultural utility of these instruments for use with diverse …

Gis Automated Delineation And Analysis Of Cancer Service Areas In The United States, Changzhen Wang

LSU Doctoral Dissertations

Delineating a meaningful and reliable geographic unit pertaining to cancer care is essential in examining geographic variations in cancer care for better analysis, management, and planning. Public health researchers have devoted great efforts to defining various service areas, which; however, lack scientific rigor or are unrepresentative of the highly specialized cancer care markets, and their methods have become obsolete in the era of big data and high geo-computation. This study develops the “Spatially Constrained Leiden (ScLeiden)” method, a network community detection algorithm in Geographic Information Systems (GIS), and applies it to delineate a series of coherent cancer service …
