Coupled Landscape And Channel Dynamics Across The Ganges-Brahmaputra Tidal-Fluvial Continuum, Southwest Bangladesh, Edwin Jefferson Bomer Iv

LSU Doctoral Dissertations

The Ganges-Brahmaputra (G-B) Delta of Bangladesh and India is widely considered to be one of the most vulnerable coastal systems in the world, owing to locally-accelerated sea level rise and landscape modification by human activities. Recent research efforts have identified pronounced elevation differences between natural and embanked areas in the G-B tidal delta plain, suggesting that natural landscapes are keeping pace with sea-level rise while anthropogenic locations are actively subsiding. However, this observation represents a singular point in time, and longitudinal trends of surface elevation in these regions are presently unknown. For communities residing in upstream regions of G-B delta …

Derivational Development: Derivational Word Processing In Three English-Speaking Populations, Lisa Suzanne Kemp

LSU Doctoral Dissertations

Native-English speaking adults use morphological decomposition to understand complex words (e.g. farmer becomes farm-er). Whether decomposition is driven by semantic organization is still unclear. It is also unclear whether ESL adults and elementary age children use the same word processing strategies as native speaking adults. This study tested an identical experimental procedure across three English-speaking populations: native speaking adults, non-native speaking adults and elementary age children. The first task tested how readers use base and suffix information in complex words and nonwords when the word featured only a base word, only a suffix, both a base and …

On-Demand Receiver-Centric Channel Allocation Via Constrained Vcg Auction For Spatial Spectrum Reuse, Feixiang Zhang, Xiangwei Zhou, Mingxuan Sun

Faculty Publications

Spatial spectrum reuse significantly enhances spectrum utilization but requires delicate design to avoid cochannel interference. Instead of focusing solely on spectrum efficiency, we consider maximizing social welfare via channel allocation. Specifically, we propose an on-demand receiver-centric mechanism with a new factor, the supply and demand relationship. The optimal channel allocation that maximizes social welfare can be achieved by the constrained Vickrey-Clarke-Groves (VCG) auction for secondary users (SUs), but with high complexity. To simplify the constrained VCG auction, we group the SUs into maximal independent groups (MIGs) using a modified Bron-Kerbosch algorithm. We prove that truthful bidding is the optimal strategy …

Combining Virtual Reality And Machine Learning For Enhancing The Resiliency Of Transportation Infrastructure In Extreme Events, Supratik Mukhopadhyay, Yimin Zhu, Ravindra Gudishala

Publications

Traffic management models that include route choice form the basis of traffic management systems. High-fidelity models that are based on rapidly evolving contextual conditions can have significant impact on smart and energy efficient transportation. Existing traffic/route choice models are generic and are calibrated on static contextual conditions. These models do not consider dynamic contextual conditions such as the location, failure of certain portions of the road network, the social network structure of population inhabiting the region, route choices made by other drivers, extreme conditions, etc. As a result, the model’s predictions are made at an aggregate level and for a …

Deciphering Public Transit Ridership In Baton Rouge: Spatial Disaggregation Approaches, Xuan Kuai

LSU Doctoral Dissertations

Background: Surveys across the U.S. reveal that commuters driving personal vehicles spend a significant amount of time in traffic, while public transit, as an efficient commuting mode, has been largely underutilized.

Purpose: What causes a low public transit ridership? How could public transit ridership be explained by demographic, socio-economic and spatial characteristics of neighborhood? This study answers these questions by deciphering the relationships between public transit ridership and various factors in a medium-size city in southern U.S. – Baton Rouge, Louisiana.

Methods: Non-spatial and spatial data in a larger areal unit (e.g., block group) are used to infer demographic, socio-economic …

Life Satisfaction And Healthcare Utilization Among Immigrants To The United States, Merritt Christian Rachel Harrelson

LSU Master's Theses

Previous research suggests a relationship between life satisfaction and healthcare utilization or HCU (Habibov & Afandi, 2016; Kim, Park, Sun, Smith, & Peterson, 2014). However, no study was found that examined this relationship among elderly American immigrants. The purpose of this study was to determine whether life satisfaction is linked to HCU for this population. The researcher of the current study applied binary logistic regression to data taken from the Health and Retirement Survey to determine whether changes in life satisfaction could be linked to variance in HCU across seven domains, including hospitalization, overnight nursing home stays, doctors visits, dentist …

Giving Four-Year-Old Children A "Voice" Within The Comprehensive Evaluation Of Quality Teaching Practices, Mistie M. Perry

LSU Doctoral Dissertations

Educational research has largely focused on the correlation between governmental entities and classroom pedagogy as policymakers develop more comprehensive evaluation systems that raise the expectations of teacher quality. However, some researchers in the field of early childhood suggest the measurement of teacher quality is largely a “mismatch between informant-based, retroactive methods” (Downer, Booren, Lima, Luckner, & Pianta, 2010, p. 5) as developmentally appropriate measurements of early childhood quality that include the perceptions of the children are few. To examine the potential for researchers to consider the inclusion of children’s perceptions within evaluation systems, this study examines the following area of …

Spatial Variability Of Mangrove Primary Productivity In The Neotropics, Rafaela De Albuquerque Ribeiro, André Scarlate Rovai, Robert R. Twilley, Edward Castañeda-Moya

Faculty Publications

Mangroves are considered one of the most productive ecosystems in the world with significant contributions as carbon sinks in the biosphere. Yet few attempts have been made to assess global patterns in mangrove net primary productivity, except for a few assumptions relating litterfall rates to variation in latitude. We combined geophysical and climatic variables to predict mangrove litterfall rates at continental scale. On a per-area basis, carbon flux in litterfall in the neotropics is estimated at 5 MgC·ha⁻¹·yr⁻¹, between 20% and 50% higher than previous estimates. Annual carbon fixed in mangrove litterfall in the neotropics is …

Karst Sinkhole Detecting And Mapping Using Airborne Lidar, Su Zhang, Shirley Baros, Susan Bogus

Publications

The focus of this study is to detect sinkhole hazards using airborne light detection and ranging (LiDAR) data. The premise is sinkholes, particularly those close to transportation infrastructure assets, could cause substantial damages to infrastructure assets, and therefore, being able to accurately and rapidly detect them is essential. However, it is expensive, time-consuming, labor-intensive, and unsafe to survey sinkholes using conventional ground observation methods. This research project was focused on developing accurate and rapid airborne LiDAR-based sinkhole detection and mapping methods, and transfer the technologies to transportation engineers for implementation and workforce development. The project team also identified best practices …

Determining The Presence Or Absence Of Euscepes Postfasciatus In Haiti And Use Of Molecular Markers For The Distinction Of Cylas Formicarius Elangantulus Biotypes, Marie Rachele Lexidort

LSU Master's Theses

Cylas formicarius elegantulus (Summers) and Euscepes postfaciatus (Fairmaire) are the most destructive sweetpotato weevils in the Caribean Basin. However, damage occurring in sweetpotato production in Haiti is attributed to C. formicarius (S), since it is known to be the most prevalent species while, conflicting information is available pertaining to the occurrence of the E. postfaciatus (F). This study was conducted in the summer of 2018 to determine the presence or absence of E. postfaciatus (F) in Haiti. 98 weevil samples from field (70% ) and infested sweetpotato roots from field and regional markets were collected (30%) in the most relevant …

Two New Species Of Shrew-Rats (Rhynchomys: Muridae: Rodentia) From Luzon Island, Philippines, Eric A. Rickart, Danilo S. Balete, Robert M. Timm, Phillip A. Alviola, Jacob A. Esselstyn, Lawrence R. Heaney

Faculty Publications

The murine genus Rhynchomys includes the large-bodied Philippine "shrew-rats," highly specialized members of the vermivorous clade of Philippine murids. Four species are recognized, all of which are endemic to Luzon Island: R. soricoides from mountains within the Central Cordillera, R. isarogensis from Mt. Isarog on the Bicol Peninsula, R. banahao from Mt. Banahaw in south-central Luzon, and R. tapulao from Mt. Tapulao in the Zambales Mountains. Field surveys in 2006 and 2008 revealed two additional populations of Rhynchomys, one from Mt. Labo (1,544 m), a dormant stratovolcano at the base of the Bicol Peninsula, the other from Mt. Mingan (1,901 …

Implications Of Poultry Litter Usage For Electricity Production, Qiuzhou Ma, Krishna P. Paudel, Doleswar Bhandari, Chandra Theegala, Molly Cisneros

Faculty Publications

© 2019 Elsevier Ltd Poultry litter has the potential to cause water quality problems if it is not applied properly to the land as a crop nutrient. Based on the data available from a survey of Louisiana poultry producers, we find that it is not cost effective to transport poultry litter farther than 38.6 km from the production facilities for crop nutrient purposes. This limited breakeven distance restricts the movement of poultry litter and points to a need to identify an alternative disposal method. We review common methods of producing electricity from poultry litter. We identify the minimum cost solution …

Mathematics Experiences Of Students Who Are Blind Or Visually Impaired, Michaela Patricia Stone

LSU Doctoral Dissertations

Historically, researchers studying mathematics education for students with visual impairment (SVI) have faced several challenges. Quantitative researchers are limited by small sample sizes and the need to adapt traditional research instruments for accessibility by SVI. Qualitative research, most often conducted by sighted researchers and relying on the perspectives of sighted educators, suffers from the absence of the voices of the SVI being studied. Overwhelmingly, research on the mathematics education of SVI is explicitly grounded in deficit models of disability, falsely conflating the physical condition of impairment with the social act of disablement. Only in the past decade have critical disability …

La distribution of the variants and linguistic and social predictors that condition the expression of possession are compared among the two cities. The results indicate that …

Verifying Modeling And Audiovisual Stimuli As Strategies For Mastering Guedes Peixoto's Maracatú, Rodrigo Clementino Diniz

LSU Master's Theses

ABSTRACT

Literature has been saying that auditory Modeling can be a useful tool in order to develop or broaden musical interpretive ideas. In the same way, literature ventilates that audiovisual stimuli can be applied to musicians in order to raise emotions that some scholars consider as indispensable when it comes to deliver expressive musical communications. More specifically, research in the Music Performance field points out that Modeling and Audiovisual stimuli are useful strategies in the learning process of building up a musical interpretation, both, fostering expressive tools for aiming musical performance.

This research is intended to empirically verify the applicability …

Politics And Religion During The Rise And Reign Of Anne Boleyn, Megan E. Scherrer

LSU Master's Theses

During the 1520s and 1530s England endured a tumultuous time of drastic political change and religious reform. At the heart of it all was Anne Boleyn, whose relationship with King Henry VIII launched the English Reformation and the Royal Supremacy, and whose tragic end became a story passed down through the current day. This work examines Anne’s life, particularly her religion and influence in politics, and the figures who shone and dimmed as she came to power and once she lost everything. Some of the most significant of these figures include Cardinal Thomas Wolsey, Sir Thomas More, Thomas Cromwell, Hugh …

Agricultural Education Teachers' Perceptions And Use Of Environmental Education In Louisiana Schools, Olivia M. Soler

LSU Master's Theses

The purpose of this study was to describe the status of environmental education (EE) in Louisiana high school agriculture classrooms. A census of Louisiana Agriscience Teacher Association (LATA) members was conducted to understand their perceptions, attitudes, and barriers regarding EE implementation. Icek Ajzen’s Theory of Planned Behavior was utilized as the theoretical framework. Data were collected through an online survey research method and analyzed using descriptive statistics. Results suggest that most LATA members incorporate EE into their curriculum relatively sparingly, perceive EE to be beneficial for students, and are in need of funding to incorporate EE into their curriculum as …
