Retrieval-Based Word Learning In Young Typically Developing Children And Children With Developmental Language Disorder I: The Benefits Of Repeated Retrieval, Laurence B. Leonard, Jeffrey Karpicke, Patricia Deevy, Christine Weber, Sharon Christ, Eileen Haebig, Sofía Souto, Justin B. Kueser, Windi Krok

Faculty Publications

Purpose: Scholars have long noted that retention improves significantly when learners frequently test themselves on the new material rather than engage in continuous study with no intermittent testing. In this study, we apply the notion of repeated testing or retrieval to the process of word learning in preschool-age children with and without developmental language disorder (DLD). Method: Novel words and their meanings were taught to 10 children with DLD and 10 typically developing (TD) children matched on age (DLD, M = 63.4 months; TD, M = 63.2 months). Recall was assessed immediately after the 2nd learning session and then again …

Influence Of Spatial Camera Resolution In Highspeed Videoendoscopy On Laryngeal Parameters, Patrick Schlegel, Melda Kunduk, Michael Stingl, Marion Semmler, Michael Döllinger, Christopher Bohr, Anne Schützenberger

Faculty Publications

In laryngeal high-speed videoendoscopy (HSV) the area between the vibrating vocal folds during phonation is of interest, being referred to as glottal area waveform (GAW). Varying camera resolution may influence parameters computed on the GAW and hence hinder the comparability between examinations. This study investigates the influence of spatial camera resolution on quantitative vocal fold vibratory function parameters obtained from the GAW. In total 40 HSV recordings during sustained phonation (20 healthy males and 20 healthy females) were investigated. A clinically used Photron Fastcam MC2 camera with a frame rate of 4000 fps and a spatial resolution of 512×256 pixels …

Acoustic Characteristics Of Vowels Produced By Young Children From The New Orleans Area, Rebecca E. Dorsa

LSU Master's Theses

Understanding dialects and their effects on speech and language is integral to the field of speech-language pathology, as dialectal differences could potentially be misdiagnosed as speech or language disorders if these factors are not well-considered. The number and organization of the vowel system of one regional dialect of American English differs from those of another regional dialects. Therefore, understanding the effect of dialect on vowel productions in children can aid in the accurate evaluation of children from various dialectal backgrounds. The aims of the proposed study were to 1) determine the age at which young children develop acoustic markers of …

Distributed Wireless Algorithms For Rfid Systems: Grouping Proofs And Cardinality Estimation, Vanya D. Cherneva

LSU Doctoral Dissertations

The breadth and depth of the use of Radio Frequency Identification (RFID) are becoming more substantial. RFID is a technology useful for identifying unique items through radio waves. We design algorithms on RFID-based systems for the Grouping Proof and Cardinality Estimation problems.

A grouping-proof protocol is evidence that a reader simultaneously scanned the RFID tags in a group. In many practical scenarios, grouping-proofs greatly expand the potential of RFID-based systems such as supply chain applications, simultaneous scanning of multiple forms of IDs in banks or airports, and government paperwork. The design of RFID grouping-proofs that provide optimal security, privacy, and …

Marcela: Emociones, Geografía E Intelectualidad, Maria D. Garcia De La Torre

LSU Master's Theses

By positioning Marcela at the field because she prefers honest conversation with young women instead of the superficiality of the court, Cervantes invites us to consider the debate of “disregard of the court and worship of the small village” from a different perspective. Marcela’s set out towards the field entails a much complex meaning which until now has been recognized. Her set out from the court turns out to be part of a Cervantine strategy which seeks to display the field as a natural space whose self-development makes possible “culture” or the speech of reason and not only as the …

Acquiring Native-Like Norms Of Making A Request In Spanish During Short-Term Study Abroad In Argentina And Spain, Christine H. Song

LSU Master's Theses

The current study examines if L2 learners of Spanish acquire native-like norms of making a request during short-term study abroad in Argentina and Spain via Discourse Completion Tasks (DCT). The investigation included 3 groups of the participants: an experimental group of 15 U.S. students who studied in Argentina or Spain; a control group of 12 U.S. students who had not studied abroad; and a control group of 7 native speakers of Spanish. The results show that students in the study abroad group became more native-like in making a request to a certain extent. Firstly, the students in the experimental group …

"La Llorona": Evolución, Ideología Y Uso En El Mundo Hispano, Raquel Sáenz-Llano

LSU Master's Theses

This thesis studies the evolution, ideology and use of the myth of La Llorona through time in the Hispanic World. Considering this myth as one of the most known traditional narratives of the American continent, I begin by providing visual, ethnohistorical and ethnographical insights of weeping in Mesoamerica and South America and the specific mention of a weeping woman in some Spanish chronicles to say how western values were stablished in “the new continent” through this legend. I suggest that during the postcolonialism the legend did not tell anymore about a mother that cries and search a place for their …

Relationship Between Subject Pronoun And Verb Finite Marking In Aae-Speaking Children, Emily C. Sossaman

LSU Master's Theses

Children learning General American English (GAE) show a relationship between their case marking of subject pronouns and their marking of finite verbs, and this relationship has been found for children with specific language impairment (SLI) and typically developing controls (TD). The relationship between children’s case marking of subject pronouns and finite verb marking has not been examined in children who speak dialects of English that differ from GAE. The purpose of the current study was to examine this relationship in children learning African American English (AAE) as this dialect differs from GAE. The data came from an archival dataset of …

Use Of Video-Models To Teach Language Stimulation Techniques, Jason Killian

LSU Master's Theses

The current study was designed to assess the feasibility of creating videos depicting Enhanced Milieu Teaching (EMT) support strategies and presenting them to graduate students in a communication sciences and disorders program, and whether differences in accuracy existed between first- and second-year graduate students. EMT support strategies were chosen due to the previous successes found within the literature. Twelve videos were presented to ten graduate students. Each participant response was analyzed for accuracy and overall responses were compiled to create overall video clarity.

Results showed that the Communication Temptation EMT support strategy videos achieved the highest levels of clarity, while …

Campus-Based Sexual Assault: The #Metoo Movement And Students' Understanding Of Issues Around Consent, Genevieve Hampson

LSU Master's Theses

College students who have experienced sexual assault are at higher risk for negative impacts involving physical and mental heath. In addition, appropriate resources and positive systematic response to disclosure are pivotal in the recovery process of survivors. Empirically relevant research has focused on campus-based sexual assault and interrelationships among variables surrounding students’ attitudes towards explicit sexual consent. This cross-sectional descriptive study of 110 students enrolled in two freshman sociology classes contributes to the emerging body of research regarding the use of social media platforms to raise awareness of sexual assault by examining students’ sociodemographic characteristics, literacy using technology, rape myth …

Assessment And Correction Of Lidar-Derived Dems In The Coastal Marshes Of Louisiana, William M. Lauve

LSU Master's Theses

The onset of airborne light detection and ranging (lidar) has resulted in expansive, precise digital elevation models (DEMs). DEMs are essential for modeling complex systems, such as the coastal land margin of Louisiana. They are used for many applications (e.g. tide, storm surge, and ecological modeling) and by diverse groups (e.g. state and federal agencies, NGOs, and academia). However, in a marsh environment, it is difficult for airborne lidar to produce accurate bare-earth measurements and even accurate elevations are rarely verified by ground truth data. The accuracy of lidar in marshes is limited by the sensor’s resolution …

Factors Related To Parental Stress At Early Diagnostic Assessments For Autism Spectrum Disorder, Abigail Issarraras

LSU Master's Theses

Autism Spectrum Disorder (ASD) is marked by pervasive impairments in social communication and restricted, repetitive interests, behaviors, and activities. Parents raising a child with ASD have consistently reported higher levels of parenting stress compared to parents of typically developing children and children with other disabilities. Several different factors influence parental stress levels at different stages of their child’s life, and so an understanding of the most predictive factors of parental stress at initial ASD assessments is critical to best serving the needs of families with a new diagnosis. The current study investigated several factors that may impact parenting stress at …

Natural Gas Conversion Into Value Added Chemicals Using Solid Acid Catalysts, Swarom Ravindra Kanitkar

LSU Doctoral Dissertations

Direct, non-oxidative conversion of natural gas to value-added chemicals has been identified as one of the grand challenges of the 21^st century. Circumventing indirect and costly reforming steps is highly sought after and solid acids can play an important role in that.

The direct conversion of methane to higher hydrocarbons and hydrogen can be catalyzed using “superacids” at < 450 °C. Reported superacid catalysts in solid, liquid, and gas phase included sulfated zirconia (SZ), HF-SbF₅, FSO₃H-SbF₅, and HBr-AlBr₃. Liquid and gas phase superacids presented difficulties in separation while the solid ones provided low yields. Here, we report a new class of Br-based solid superacids, AlBr_x/H-ZSM-5 (“ABZ-5”, …

While advertising and persuasion is a widely researched area in mass communication, the impact of health marketing on consumer behavior remains a relatively new arena. The complex health information landscape online is comprised of both public health organizations seeking to improve health behaviors as well as businesses seeking to sell their products or services. It is well documented in the communication literature that the source of information can impact the recipient in a multitude of ways. Digital health literacy is undoubtedly an essential skill for anyone interacting with health information online, spurring the question, do individuals with low and high …

Self-Healing Composite Of Thermoset Polymer And Programmed Super Contraction Fibers, Guoqiang Li, Harper Meng

College of Engineering Patents

A composition comprising thermoset polymer, shape memory polymer to facilitate macro scale damage closure, and means for molecular scale healing has the ability to repair structural defects by a bio-mimetic, close-then-heal process. The shape memory polymer serves to bring surfaces of a structural defect into proximity, after which the healing means moves into the defect and provides molecular scale healing. The means for molecular scale healing can be a thermoplastic, such as fibers, particles or spheres, which are heated to or above the thermoplastic's melting point, and then the composition is cooled below that melting temperature. The compositions can not …

Pragmatics And Pedagogy In University Level Spanish Second Language Textbooks, Vanessa M. Cardenas

(2008), Conexiones (2010), and Interacciones (2013). The purpose of this investigation is to closely examine if the L2Ts communicatively present the speech acts of requesting, refusing, and apologizing, and address forms, with sufficient pragmatic context for the L2 learner to acquire native-like production. The results have shown that the speech acts under …

Sowing The Wild Oats: Scandal And Crisis In The Louisiana Grain Industry, Chandler Taylor

LSU Master's Theses

In 1972, U.S. Agriculture Secretary Earl L. Butz commented, "The grain trade is one of the most fiercely competitive industries in this country;" yet to the general public, the grain trade is a largely unknown entity.[1]Sowing the Wild Oatsseeks to address some of the gaps in our knowledge of the grain industry created by the industry’s general invisibility and a lack of writing on the topic, particularly in reference to the latter half of the twentieth century. In the mid-twentieth century, a major investigation of the New Orleans grain trade sparked national changes affecting the entire United …

Parents’ Perspectives Of Cultural Competence In Schools: The Initial Development Of The Culturally Competent School Community Scale, Aijah Kai Baruti Goodwin

LSU Master's Theses

Diversity in school settings is continuously changing with an increase of minority students in the United States school systems. The present study uses a phenomenological approach to gain parents’ experiences related to culturally responsive and competent practices in their child(ren)’s schools. Interviews were conducted with 10 culturally diverse parents with children in preschool and/or elementary school. The interviews were transcribed verbatim, coded for common themes and analyzed for the frequency and prevalence of the themes in preschool vs. elementary school settings. An analysis of the interviews revealed 6 themes related to culturally competent and responsive practices in school settings. The …

A Retrospective Analysis And Method Validation Of Postmortem Interval Estimation In Louisiana, Sophia Reck

LSU Master's Theses

Forensic anthropologists are often called upon to assess the postmortem interval (PMI; i.e. time since death) of remains in varying states of decomposition and skeletonization. These assessments rely on familiarity with general taphonomic sequences and processes, in addition to experience with how these processes present in local environments and conditions. Assessment using such qualitative methods is a subjective process. Therefore, some researchers have developed formulae whose purpose is to estimate PMI in an objective format. In these instances, the resultant PMI estimation formulae were developed using local data and therefore have the potential for local applicability. Additionally, for some regions, …

Twitter Use In Hurricane Isaac And Its Implications To Disaster Resilience, Kejin Wang

LSU Master's Theses

Disaster Resilience is the capacity of a community to ‘bounce back’ from disastrous events. Most studies rely on traditional data such as census data to study community resilience. With the advent of social media era, the new data source gives us an opportunity to explore the application of Twitter data to better understand disaster resilience. A research question is: does Twitter use correlate with disaster resilience? In other words, will communities with more Twitter users be more resilient to disasters, presumably because they are more likely to be better informed? The underlying issue is that if there are social and …

The New British Christianity Of C.S. Lewis, Thomas Kemp

LSU Master's Theses

The emergence of C.S. Lewis as a popular author known for Christian content during the second half of the twentieth century provides an ideal case study for the transformation of religiosity within Britain. As religious behavior shifted from institutional adherence to private experience, Lewis became a ‘popular theologian’ who represented Christianity both for Christians – who looked to him for spiritual inspiration– and for non-Christians – who treated his views as representative of contemporary Christianity. By analyzing the reception, representation, and use of Lewis (his figure and his work) throughout the twentieth-century and into the twenty-first, it becomes clear that …

Quantifying Coherence In A Transdiagnostic Sample: A Methodological Investigation Of Computationally-Derived Coherence Using Ambulatory Assessment, Taylor L. Fedechko

LSU Master's Theses

Schizophrenia is a clinical diagnosis assigned to individuals that experience positive (e.g., hallucinations and delusions), negative (e.g., blunted affect), and disorganized (e.g., incoherent speech) symptoms. One particularly disabling symptom is incoherence, which is defined as the meaning-based relationship between ideas. This symptom can drastically affect an individual’s quality of life by affecting areas such as social and occupational functioning. Currently, the mechanism behind this symptom is unknown and requires further study. One way to examine incoherence is to understand its level of expression in other clinical populations. With the advent of computationally-derived natural language processing (NLP), coherence can be quantified …

Monumental Discourse: Elite And Grassroots Disputes Over White Supremacist Monuments In New Orleans, Jude Bumgardner

LSU Master's Theses

This thesis explores elite and grassroots discourse concerning disputes over monument removal in New Orleans, Louisiana. By means of participant observation, narrative ethnography, and critical discourse analysis, I ground this study of political and academic arguments about Confederate monuments in the context of grassroots concerns regarding white supremacist symbols to inquire about how these divergent discourses relate to inequality in New Orleans. Ultimately, I argue that what is most at stake in each case studied here is speakers’ control over the “public mind” via their control over dominant narratives (van Dijk 1993a, 44-45). In order to preserve their power, each …

Modeling Crowd Feedback In The Mobile App Market, Grant S. Williams

LSU Doctoral Dissertations

Mobile application (app) stores, such as Google Play and the Apple App Store, have recently emerged as a new model of online distribution platform. These stores have expanded in size in the past five years to host millions of apps, offering end-users of mobile software virtually unlimited options to choose from. In such a competitive market, no app is too big to fail. In fact, recent evidence has shown that most apps lose their users within the first 90 days after initial release. Therefore, app developers have to remain up-to-date with their end-users’ needs in order to survive. Staying close …
