Faculty Publications

Workforce training is needed throughout the construction industry to create and maintain competent workers; unfortunately, most construction training and education research focuses on university student education. Integrating education science theory into construction training has the potential to improve industry training, but the status of this integration has not been well articulated. To address this gap, this article undertakes a state-of-the-art review of education theory–integrated construction training for current industry professionals. To measure the extent of educational theory integration, this article identifies and summarizes studies that meet inclusion criteria, identifies the frequency of occurrence of Bloom’s Taxonomy verbs as a measure …

Using Distributed Techology To Make Music In The Time Of The Attention Economy, Tate Carson

LSU Doctoral Dissertations

Sounds Aware is a mobile web app that allows users to record soundwalks and share them so that other people can experience them. The creator of the soundwalk records their perceptions of the restorativeness of a specific place on the walk, these answers are then sonified for whoever experiences the walk later to hear. Sounds Aware aims to be a social app that is restorative to our attention. It does this by encouraging experience of nature and by using decentralized technology that exists outside of the attention economy.

The attention economy is discussed as a force that exists within much …

Sphincs_Bssn: A General Relativistic Smooth Particle Hydrodynamics Code For Dynamical Spacetimes, S. Rosswog, P. Diener

Faculty Publications

We present a new methodology for simulating self-gravitating general-relativistic fluids. In our approach the fluid is modelled by means of Lagrangian particles in the framework of a general-relativistic (GR) smoothed particle hydrodynamics (SPH) formulation, while the spacetime is evolved on a mesh according to the Baumgarte-Shapiro-Shibata-Nakamura (BSSN) formulation that is also frequently used in Eulerian GR-hydrodynamics. To the best of our knowledge this is the first Lagrangian fully general relativistic hydrodynamics code (all previous SPH approaches used approximations to GR-gravity). A core ingredient of our particle-mesh approach is the coupling between the gas (represented by particles) and the spacetime (represented …

Noncommutative Tensor Triangular Geometry And Its Applications To Representation Theory, Kent Barton Vashaw

LSU Doctoral Dissertations

One of the cornerstones of the representation theory of Hopf algebras and finite tensor categories is the theory of support varieties. Balmer introduced tensor triangular geometry for symmetric monoidal triangulated categories, which united various support variety theories coming from disparate areas such as homotopy theory, algebraic geometry, and representation theory. In this thesis a noncommutative version will be introduced and developed. We show that this noncommutative analogue of Balmer's theory can be determined in many concrete situations via the theory of abstract support data, and can be used to classify thick tensor ideals. We prove an analogue of prime ideal …

Development Of Parameters Towards Voice Bifurcations, Takeshi Ikuma, Andrew J. Mcwhorter, Lacey Adkins, Melda Kunduk

Faculty Publications

Pathological vocal folds are known to exhibit multiple oscillation patterns, depending on tissue imbalance, subglottal pressure level, and other factors. This includes mid-phonation changes due to bifurcations in the underlying voice source system. Knowledge of when changes in oscillation patterns occur is helpful in the assessments of voice disorders, and the knowledge could be transformed into useful objective measures. Mid-phonation bifurcations can occur in rapid succession; hence, a fast classification of oscillation pattern is critical to minimize the averaging of data across bifurcations. This paper proposes frequency-ratio based short-term measures, named harmonic disturbance factor (HDF) and biphonic index (BI), towards …

FRAM (F/Photometric Robotic Atmospheric Monitor) is a robotic telescope operated at the Pierre Auger Observatory in Argentina for the purposes of atmospheric monitoring using stellar photometry. As a passive system which does not produce any light that could interfere with the observations of the fluorescence telescopes of the observatory, it complements the active monitoring systems that use lasers. We discuss the applications of stellar photometry for atmospheric monitoring at optical observatories in general and the particular modes of operation employed by the Auger FRAM. We describe in detail the technical aspects of FRAM, the hardware and software requirements for a …

Faculty Publications

Purpose: High-speed videoendoscopy (HSV) is an emerging, but barely used, endoscopy technique in the clinic to assess and diagnose voice disorders because of the lack of dedicated software to analyze the data. HSV allows to quantify the vocal fold oscillations by segmenting the glottal area. This challenging task has been tackled by various studies; however, the proposed approaches are mostly limited and not suitable for daily clinical routine. Method: We developed a user-friendly software in C# that allows the editing, motion correction, segmentation, and quantitative analysis of HSV data. We further provide pretrained deep neural networks for fully automatic glottis …

Load Balancing For Distributed Nonlocal Models Within Asynchronous Many-Task Systems, Pranav Gadikar, Patrick Diehl, Prashant K. Jha

Faculty Publications

In this work, we consider the challenges of developing a distributed solver for models based on nonlocal interactions. In nonlocal models, in contrast to the local model, such as the wave and heat partial differential equations, the material interacts with neighboring points on a larger-length scale compared to the mesh discretization. In developing a fully distributed solver, the interaction over a length scale greater than mesh size introduces additional data dependencies among the compute nodes and communication bottleneck. In this work, we carefully look at these challenges in the context of nonlocal models; to keep the presentation specific to the …

Oocyte Specific Lncrna Variant Rose Influences Oocyte And Embryo Development, Rajan Iyyappan, Daria Aleshkina, Linkai Zhu, Zongliang Jiang, Veronika Kinterova, Andrej Susor

Faculty Publications

Fully grown mammalian oocytes store a large amount of RNA synthesized during the transcriptionally active growth stage. A large part of the stored RNA belongs to the long non-coding class which contain either transcriptional noise or important contributors to cellular physiology. Despite the expanding number of studies related to lncRNAs, their influence on oocyte physiology remains enigmatic. We found an oocyte specific antisense, long non-coding RNA, “Rose” (lncRNA in Oocyte Specifically Expressed) expressed in two variants containing two and three non-coding exons, respectively. Rose is localized in the nucleus of transcriptionally active oocyte and in embryo with polysomal occupancy in …

Remembrance, Nhu Ngoc Quynh Dao

LSU Master's Theses

The artwork in the collection, “Remembrance,” is a collection of three-dimensional paper toys inspired by the culture of Dong Son civilization. The study was intended as an investigation into a mysterious, once-lost kingdom that flourished in the northern delta region of Vietnam. The designs and art motifs found on bronze artifacts from Dong Son have been scrutinized, then compared with stories in Vietnamese legends to decipher their hidden message and symbolism. I collected and translated the design motifs digitally as part of the creative process before analyzing their philosophies and intentions to not only introduce the culture but also accurately …

Blowout - Capping - Fracturing - Relief Well, A Full Cycle Workflow, Youssuf A. Elnoamany

LSU Master's Theses

Broaching is defined as the uncontrolled release of hydrocarbons to ocean seafloor after a loss of subsurface well control event. Failed attempts to cap the offshore wells undergoing worst case discharge may lead to hydraulic fracture initiation and subsequent propagation, leading to renewed release of hydrocarbon to the seafloor. During the capping stack shut-in process, pressure build-up will occur along the wellbore, exposing locations of possible fracture initiation to overpressurized fluid, such as directly below the casing shoe, and critical points along the well casing. Shall there be enough build-up pressure to exceed the minimum horizontal stress in an exposed …

LSU Master's Theses

This thesis examines the concerns and conflicts around short-term rental (STR) properties in New Orleans neighborhoods. Using data from collected from critical discourse analysis, semi-structured interviews and social media posts, this paper analyzes the ways the city of New Orleans, residents of the city, STR hosts, and platforms like Airbnb discuss issues of safety, displacement, rising costs of living, as well as responsible STR practices. To understand the complexities of the issues people, have with short-term rental properties, this project approaches STRs from a housing and gentrification lens to understand the role these properties play within in the daily atmospheres …

Mixed (F)Ixed Messages, Lauren A. Verrett

LSU Master's Theses

Many individuals have an understanding that our lives have a timeline, and this timeline is full of objectives that we perceive as absolutes. Through personal observations it has become apparent that there are many amazing men and woman that are stagnant because they were raised to believe that meeting these goalposts are a priority. In an age of individualism, it is evident that every individual has control of their own life through their actions. However, in this same age of technology and social media, the anxiety of not meeting certain requirements or standards is even more apparent than previous generations. …

Characterizing Receptive Vocabulary Knowledge In Minimally Verbal Children With Autism Spectrum Disorder, Allison Menting

LSU Master's Theses

Background: Delayed or impaired language skills are common characteristics of children with autism spectrum disorder (ASD). Currently, there is little research examining the receptive language profile in children with ASD, and even less is known about children with ASD who are minimally verbal. The current study aimed to characterize the receptive vocabulary profile of minimally verbal children with ASD and to examine whether this profile differs from their typically developing peers. Methods: Participants included 31 minimally verbal children with ASD, aged 60-118 months, who were reported to produce between 0-10 words, 124 typical developing toddlers, aged 9-14 months, who were …

Fun House, Stephanie Cobb

LSU Master's Theses

The expression “fun house” seems empathetic and joyful, but has potentially melancholy connotations. Fun houses are participatory. They allow guests to move freely through their colorful halls. At the same time, they do not organize guest’s experience. Usually, we are thoughtful of all possible contingencies that make the world so unpredictable. We prefer certainty to doubt and try to avoid risks. However, reason and order have limits. To feel alive, we must take risks. The connotation of the paintings in Fun House may imply either a sunny mood through tenderness between figures or a tense ambivalence that lingers in their …

The King Of Witchcraft: Scotland's Witchcraft Crisis And Religious Politics Under King James Vi, Tristan Rimmer

LSU Master's Theses

In 1590 King James VI of Scotland was the supposed target of diabolical witchcraft; the North Berwick witches were accused of attempting to sink the ship carrying James and his new bride from Copenhagen back to Edinburgh following their marriage. This event set off a widespread witch-hunt in Scotland, one that James took a personal and vested interest in. The hunt continued through 1597, occurring across multiple Scottish locales, resulting in judicial statute rearrangements, and famously inspiring James’ treatise Daemonologie. In addition to Daemonlogie, James also wrote multiple treatises on the theory of divine right in the midst …

On Properties Of Weil Sums Of Binomials, Liem P. Nguyen

LSU Doctoral Dissertations

This dissertation explores questions regarding the Weil sum of binomials, a finite field character sum originated from information theory. The Weil spectrum counts distinct values of the Weil sum through invertible elements in the finite field. The value of these sums and the size of the Weil spectrum are of particular interest, as they link problems in information theory, coding theory, and cryptography to other areas of math such as number theory and arithmetic geometry. In the setting of Niho exponents, we prove the Vanishing Conjecture of Helleseth ($1971$) on the presence of zero values in the Weil spectrum and …

Light Coupling Structures And Switches For Plasmonic Coaxial Waveguides, Amirreza Mahigir, Georgios Veronis

Faculty Publications

We introduce wavelength-scale light coupling structures and switches for plasmonic coaxial waveguides. We first consider single-slit structures optimized for a wavelength of 1550 nm and find that, when the slit is on resonance, the coupling to the plasmonic coaxial waveguide is maximized. We also observe that for optimized double- and triple-slit structures, the coupling efficiency is enhanced compared to the single-slit structure by factors of ˜3.02 and ˜4.21, respectively. We find that, in the case of double- and triple-slit structures, the surface plasmons excited at the metal-air interface enhance light coupling to the plasmonic coaxial waveguide via the slits. In …

The Role Of School Sociocultural Factors On The Mental Health And Academic Competence Of Elementary Aged Children, Aijah Kai Baruti Goodwin

LSU Doctoral Dissertations

Due to the diversification of school systems, schools are being challenged to engage in more culturally responsive practices to meet the needs of diverse students. Therefore, this study utilized Gay’s (2002) model of culturally responsive teaching to assess the relationship between sociocultural factors and the academic competence and mental health of elementary-aged children. This study also aimed to investigate the mediating and moderating relationship that culturally responsive classroom practices play on children’s academic competence and mental health. One hundred thirty-one diverse parents (97.7%), and legal guardians (2.3%) with children in elementary school (M_age = 8.05) were recruited for participation …

Mothering Across Borders: A Phenomenological Exploration Into The Work-Family Balance Experiences Of Jamaican Transnational Mothers In The United States, Phelecia Alecia Udoko

LSU Doctoral Dissertations

The U.S. is home to one of the largest Jamaican populations residing outside of Jamaica and comprises over 50% of the U.S.-Caribbean workforce. Despite this, the experiences of Jamaican mothers who balance domestic work and families abroad–a phenomenon known as transnational motherhood – is often overlooked in research on work-family balance. Currently, a need exists to further explore work-family balance (WFB) as the lack of it has been associated with negative organizational outcomes. The purpose of this dissertation is to understand the WFB experiences of Jamaican transnational mothers and to explore the role of institutional/national policies and culture on WFB …
