Addition And Subtraction: Coral Reproduction And Disease In A Changing Ocean, Ashley Rossin

LSU Doctoral Dissertations

Marine diseases are changing the landscapes of coral reefs particularly throughout the Western Atlantic. Stony coral tissue loss disease (SCTLD) swept through this region impacting at least 22 stony coral species. White plague (WP) is a more ephemeral disease, but still has a significant impact on coral reef health and perseverance, especially under a changing ocean. While these impacts are seen on the reef-scale, we can zoom into the tissue-level to identify disease markers for both diseases and identify their differences. This has ramifications for disease intervention, as well as mitigation strategies. Despite continuous disease outbreaks, healthy corals persist and …

Settling Preference Of Nipponaclerda Biwakoensis (Hemiptera: Aclerdidae) On Phragmites Australis Stems, Alexia Catherine Desoto

LSU Master's Theses

Phragmites australis, a wetland grass that stabilizes the Louisiana coastline, has been undergoing a major die-off near the Mississippi River Delta (MRD) since the autumn of 2016. One suspected cause for this plant decline is the attack of an invasive scale insect, Nipponaclerda biwakoensis. We lack information on the host preference of the crawlers, the life stage that decides where to settle and when to start feeding on the plant. The objectives of this study were to identify what positions along the vertical stem N. biwakoensis prefers to settle and what host-plant traits may be influencing this choice. We recorded …

Effects Of Iconic Gestures On Word Pair Learning In Autistic And Non-Autistic Adults, Caprielle G. Priola

LSU Master's Theses

Previous studies have demonstrated that simultaneous speech and iconic gestures enhance learning and memory for listeners. Additionally, metacognitive awareness, which can be measured through judgements of learning (JOLs), has also been shown to impact learning and memory. However, it has not been established that these benefits apply to all learners. Existing studies on gesture processing and metacognitive abilities in autistic adults yield mixed findings. The present study aims to investigate the impact of co-speech iconic gestures on word pair recall and perceived learning (JOLs) in autistic and non-autistic adults.

Forty non-autistic adults and 40 autistic adults participated in an online …

Geospatial Analysis Of Historical Tropical Cyclone Intensity And Rainfall In Georgia, United States, Reilly T. Corkran

LSU Master's Theses

Tropical cyclones, characterized by their high wind speeds and heavy rainfall, cause widespread devastation, affecting millions of people and leading to economic losses worldwide. Tropical cyclone-specific research in Georgia is scarce, likely due to the coast’s minimal geographical extent and the relative infrequency of direct landfalls. Research on Georgia tropical cyclones does not account for storms that make landfall in Florida and continue north, northeast, or northwest. In 2018, Hurricane Michael generated $4.7 billion in property, agriculture, and forestry damages across southwest Georgia as a Category 3 hurricane. With an increasing population, property development, and agriculture sector sensitive to tropical …

Different Error Patterns Of /L/ In Children And Speech-Language Pathologists' Perception And Treatment, Grace E. Lemoine

LSU Master's Theses

Children often simplify target speech sounds using phonological processes, or common developmental error patterns. However, some children produce less common error patterns that differ from common errors. In the current study, less common errors involving /l/ sounds were studied as the phoneme /l/ is a sound that is subject to frequent misarticulations in young children and perceptual confusion among listeners. The current study focused on less common errors because studies have suggested that atypical errors can indicate weak phonological representations and poor phonological awareness skills, which can have long-term effects on children’s literacy skills. Therefore, the aim of the current …

This thesis introduces SpectAR, an augmented reality and desktop remote collaboration software suite developed in Unreal Engine 5.1.1. SpectAR …

Speech And Language Errors In An 8-Year-Old Spanish-English Bilingual Speaker: A Case Study, Alaniss Heredia

LSU Master's Theses

Despite the growing population of Spanish-English bilingual speakers with developmental language disorders and speech sound disorders (SSD) in the United States, there is limited research on assessment for this population. Research suggests that the linguistic environment in which the Spanish-English bilingual speakers are brought up should be considered when assessing and treating this population since the Spanish-English bilingual population is diverse. One result of such environments is differences in degrees of language exposure. For example, a child can be exposed to two languages but have more exposure in one than the other. This might lead to better proficiency in one …

Relational Turbulence And Couples’ Convergence And Divergence In Weekly Highs And Lows During Three Months Of The Covid-19 Pandemic Lockdown, Shaochun Li, Denise Haunani Solomon, Kellie St Cyr Brisini

Faculty Publications

Previous research has found relational benefits of interpersonal emotional convergence. Drawing on relational turbulence theory, we expected that partners’ convergence in emotional high and low points is associated with relational uncertainty, qualities of interdependence, and relational turbulence. These hypotheses were tested using data retrieved from a longitudinal project in which spouses in 64 American married couples independently reported high and low experiences and completed relationship measures every week for ten weeks from June to August of 2020. Results from multilevel models confirmed some of the hypothesized benefits of convergence in highs, but predictions about convergence in lows were largely unsupported. …

Callous–Unemotional Traits And Emotion Perception Accuracy And Bias In Youths, Enrica Ciucci, Andrea Baroncelli, Carolina Facci, Stefania Righi, Paul J. Frick

Faculty Publications

This study investigated the associations among conduct problems, callous–unemotional (CU) traits, and indices of emotion recognition accuracy and emotion recognition bias obtained from human faces. Impairments in emotion recognition were considered within broader, impaired emotional and social functioning. The sample consisted of 293 middle-school students (51.19% girls; M age = 12.97 years, SD = 0.88 years). In general, CU traits were associated with less accuracy in recognizing emotions, especially fearful and angry faces, and such deficits in emotional recognition were not associated with conduct problems independent of CU traits. These results support the importance of studying potential deficits in the …
