Data included 4,537 infinitival TO contexts extracted from language samples; each was coded as zero or overtly marked and by preceding verb context (i.e., verbs …

Dissolved Carbon In A Large Variety Of Lakes Across Five Limnetic Regions In China, Kaishan Song, Zhidan Wen, Yijun Xu, Hong Yang, Lili Lyu, Ying Zhao, Chong Fang, Yingxin Shang, Jia Du

Faculty Publications

Dissolved carbon in lakes play a vital role in the global carbon cycling. The concentration and dynamics of lake dissolved carbon can be influenced by both the surrounding landscape and a combination of physical, chemical and biological processes within the lakes themselves. From 2009 to 2016, we conducted a large-scale assessment of dissolved organic carbon (DOC) and dissolved inorganic carbon (DIC) in 249 lakes across a diverse range of climatic, geopedologic, topographical and hydrological conditions in five Chinese limnetic regions: the East Limnetic Region (ELR), the Northeast Limnetic Region (NLR), the Inner Mongolia-Xinjiang Limnetic Region (MXR), the Yungui Limnetic Region …

On Working From Within: Understanding Self And Story, Bruce Parker

LSU Doctoral Dissertations

Curriculum theory explores teaching and learning both in and out of schools. This research continues to engage with teachers and students as complex individuals whose identities and experiences influence their education and their approaches to teaching and learning. This research examines questions of self and story using autobiographical and autoethnographic methods. The project begins with an overview of some of the challenges public education and teachers have met with in the past two decades. One outcome of those challenges is control of the curriculum and classroom time has increasingly been taken away from students and teachers and given to administrators …

An Evaluation Of The Utility Of A Mass-Weighted Frequency Distribution Of Sediment For Modeling Aeolian Transport Rates, Raihan Jamil

LSU Master's Theses

Predictions made by aeolian transport models often do not match well with measured data. The poor predictive capability of these models remains a fundamental problem in aeolian geomorphology. This study evaluates the effectiveness of the recently proposed mass-weighted frequency distribution (Edwards and Namikas 2015) and the apparent von Kármán parameter proposed by Li et al. (2010) to improve transport rate predictions. The evaluation consists of comparisons of predicted transport rates versus a large dataset of measured field and lab transport rates collected from the literature. The transport rate predictions are made both with and without recalibration of model empirical coefficients. …

Madden-Julian Oscillation Relationships With Cool Season Cyclogenesis, Daily Precipitation, And Cool Season Severe Weather Frequencies In The Gulf Of Mexico Region, Stephen Paul Caparotta

LSU Doctoral Dissertations

Tropical cyclone variability in the Gulf of Mexico (GoM) has been the focus of a considerable amount of research. Variability on both interannual scales, related to the El Niño-Southern Oscillation (ENSO), and on subseasonal scales, related to the Madden-Julian Oscillation (MJO), is well documented. By contrast, very little research exists on the relationships between the MJO and cool season, non-tropical cyclones in the GoM.

The MJO influence on cool season (October-March) cyclogenesis in the GoM variability is explored here. Additionally, daily precipitation variability and cool season severe weather variability is examined for areas near and just inland of the GoM. …

"If You Stand On This Corner, People Know What You're About": Powerful Geographies Of Airline & Goodwood In #Justiceforalton, Shannon Kathleen Groll

LSU Master's Theses

This thesis seeks to understand the multiple geographies of Airline & Goodwood, a site of protest occupied nightly during a part of summer 2016 in response to the police shooting of Alton Sterling. Through a methodology of observant-participation, interviews, and oral histories, I make the case that the politics of this site differed from other contemporaneous protest sites in the city through specific place-making activity which highlighted the site’s powerful contemporary and historical geographies. I connect protest at this site to the precarity of Black life and death in Baton Rouge through interviews and oral histories which discuss the historical …

Dendroecology is the science that dates tree rings to their exact calendar year of formation to study processes that influence forest ecology (e.g., Speer 2010 [1], Amoroso et al., 2017 [2]). Reconstruction of past fire regimes is a core application of dendroecology, linking fire history to population dynamics and climate effects on tree growth and survivorship. Since the early 20th century when dendrochronologists recognized that tree rings retained fire scars (e.g., Figure 1), and hence a record of past fires, they have conducted studies worldwide to reconstruct [2] the historical range …

Construction Of A Tropical Cyclone Size Dataset Using Retroactive Analysis Data With A Damage Application, Derek Trent Thompson

LSU Master's Theses

This thesis introduces a new tropical cyclone (TC) size dataset. Using the radius of the outermost closed isobar (ROCI) as the size metric of focus, a comprehensive record of TC size at landfall was constructed for tropical storms and hurricanes that made landfall in the United States along the East Coast and in the Gulf of Mexico. The ROCI information was derived from mean sea level pressure maps generated using the NCEP/NCAR Reanalysis I dataset over a 69-year period (1948 – 2016). Construction of the dataset involved using two methodologies, one based on hourly interpolated HURDAT2 best tracks and the …

A Performer’S Guide To Poema De Sete Faces, Song Cycle By Jeffrey Perry, Paulo Henrique Campos Silva

LSU Doctoral Dissertations

The American composer Jeffrey Perry composed the song cycle Poema de sete faces (Poem of seven faces), for tenor or soprano and piano, based on the poem of the same name by Carlos Drummond de Andrade, one of the greatest Brazilian modernist poets of the 20th century. Both Drummond’s poem and Perry’s music were written to be open to multiple interpretations. Together, the possibilities for their interpretation are even broader. This dissertation discusses the art that emerges at the intersection of the poem and the music from the perspective of the singer. I present a biography and an overview of …

Understanding “Southern” Identities And Confederate Iconography: Internal Orientalism, (Mis)Representation, And Social Media, Robert W. Perham

LSU Master's Theses

In light of recent debates surrounding Confederate iconography (flags, statues and symbols), this thesis has three foci. First, the continued construction of the American “South” as an internal “Other.” Second, the reactive perspectives taken by self-identifying “Southerners” who both support and denounce Confederate iconography. Third, the role that social media platforms (Facebook, Twitter and Instagram) have as sites that both disseminate hegemonic discourse and facilitate resistance. Drawing on a Foucauldian discourse analysis of content (news articles, posts, videos, images, memes) published and discussed on social media, I explore whether "the South" continues to be portrayed as a lesser "Other" nationally, …

A Novel Multiproxy Approach To Reconstructing Sea Surface Temperature In The Southwestern Gulf Of Mexico, Marissa Anne Vara

LSU Master's Theses

Coral Sr/Ca is a widely-used proxy for sea surface temperature (SST); however, discrepancies in the coral Sr/Ca-SST relationship among colonies of the same species makes uncertainty in absolute temperature reconstructions larger than the climate signal yet climate variability studies are possible. Furthermore, the riverine input of terrestrial carbonate weathering products to the coastal waters can disrupt the coral Sr/Ca-SST signal by changing local seawater chemistry. This study evaluates the fidelity and reproducibly of coral SST proxies (Sr/Ca, Li/Ca, Mg/Li, Sr-U, Mg/Ca, and U/Ca) and a riverine-upwelling proxy (Ba/Ca) in four Orbicella faveolata colonies in two reefs offshore from Veracruz, Mexico …

A Climatology Of Precipitation Days Throughout The Continguous United States, Rudy J. Bartels

LSU Doctoral Dissertations

Precipitation can affect many sectors including agriculture, socio-economic activities and hazard management. This dissertation addresses the temporal aspect of precipitation using 167 first order stations in the contiguous United States from 1951-2015. The three objectives of this dissertation are to perform (1) an annual analysis of the frequency of rain days in the United States and changing magnitudes of daily rainfall, (2) seasonal rain day frequency in the United States, and (3) use an artificial neural …

At The Edge Of Humanity: American Indian Legal Identity And The Development Of American Citizenship, Zachary Charles Isenhower

LSU Doctoral Dissertations

Civic standing in the formative era of the United States was defined by land ownership. Landless white Americans demanded access to western lands, while the American government regulated settler pressure on the borderlands in order to preserve peace, and maintain its authority over citizens. Simultaneously, the U.S. depended upon western lands for revenue and on settlers for expanding its domain. As acquisition of property by white Americans depended in very real terms on dispossessing Indians of their lands, justifying that dispossession became one of the most fraught intellectual processes in American thought.

This project explores how civic identity was not …

A Bell test is a randomized trial that compares experimental observations against the philosophical worldview of local realism 1, in which the properties of the physical world are independent of our observation of them and no signal travels faster than light. A Bell test requires spatially distributed entanglement, fast and high-efficiency detection and unpredictable measurement settings 2,3 . Although technology can satisfy the first two of these requirements 4-7, the use of physical devices to choose settings in a Bell test involves making assumptions about the physics that one aims to test. Bell himself noted this weakness in using physical …

Assessing The Influence Of Precipitation On Shallow Groundwater Table Response Using A Combination Of Singular Value Decomposition And Cross-Wavelet Approaches, Peng Qi, Guangxin Zhang, Y. Jun Xu, Lei Wang, Changchun Ding, Chunyang Cheng

Faculty Publications

Identifying the spatiotemporal change of the groundwater table to precipitation at the river basin scale can be important for regional water resource management. In this study, we proposed a method that combines singular value decomposition and cross-wavelet approaches to analyze the relationship between groundwater level dynamics and precipitation. The method was applied to the Naoli River Basin, Northeast China. Moreover, the method of continuous wavelet using fast Fourier transform was also used to reveal clearly the relationship between groundwater level and heavy precipitation. The results showed that the major mode of relationship between groundwater and precipitation was divided into four …

Event-Based Climatology Of Tropical Cyclone Rainfall In Houston, Texas And Miami, Florida, Jill C. Trepanier, Clay S. Tucker

Stratigraphic Reconstruction Of A Late Pleistocene Bald Cypress Forest Discovered On The Northern Gulf Of Mexico Continental Shelf, Suyapa Michell Gonzalez Rodriguez

LSU Master's Theses

A previously buried bald cypress forest (Taxodium distichum) was discovered on the continental shelf, offshore of Orange Beach, Alabama, USA, in ~20 m water depth. The forest was exhumed by Hurricane Ivan in 2004, and is now exposed as stumps in life position in a trough located in the northern Gulf of Mexico continental shelf seafloor. We are investigating the local stratigraphy, paleo-landscape, and mode of forest preservation of this unique site. In August 2015 and July 2016, submersible vibracores (18 in total) were collected. Core analysis included: bulk density and imaging via Geotek multi sensor core logger, …

Characterizing Severe Weather Potential In Synoptically Weakly Forced Thunderstorm Environments, Paul W. Miller, Thomas L. Mote

Faculty Publications

Abstract. Weakly forced thunderstorms (WFTs), short-lived convection forming in synoptically quiescent regimes, are a contemporary forecasting challenge. The convective environments that support severe WFTs are often similar to those that yield only non-severe WFTs and, additionally, only a small proportion of individual WFTs will ultimately produce severe weather. The purpose of this study is to better characterize the relative severe weather potential in these settings as a function of the convective environment. Thirty-one near-storm convective parameters for > 200 000 WFTs in the Southeastern United States are calculated from a high-resolution numerical forecasting model, the Rapid Refresh (RAP). For each parameter, …

Incremental Landscape At A Baton Rouge Oil Refinery: Temporal Framework For Phytoremediation In Louisiana Cancer Alley, Dahyung Yang

LSU Master's Theses

There is a rising need for clear guidance for phytoremediation applications in contaminated land, in anticipation of the severity of the pollution problem in the petrochemical industrial area. Results of a demographic survey of Louisiana neighborhoods adjacent to petrochemical plants indicated that both deep-rooted environmental issues and social inequity are an inherent part of many communities. This research simulated a temporal framework for incremental landscape at a Baton Rouge oil refinery and its surrounding neighborhood using phytoremediation principles with local plants and insects. Through this novel ecosystem, the site will become biodiverse, and community members will be able to explore …

Effects Of Sea Level Rise, Land Subsidence, Bathymetric Change And Typhoon Tracks On Storm Flooding In The Coastal Areas Of Shanghai, Jun Wang, Si Yi, Mengya Li, Lei Wang, Chengcheng Song

Faculty Publications

We compared the effects of three key environmental factors of coastal flooding: sea level rise (SLR), land subsidence (LS) and bathymetric change (BC) in the coastal areas of Shanghai. We use the hydrological simulation model MIKE 21 to simulate flood magnitudes under multiple scenarios created from combinations of the key environmental factors projected to year 2030 and 2050. Historical typhoons (TC9711, TC8114, TC0012, TC0205 and TC1109), which caused extremely high surges and considerable losses, were selected as reference tracks to generate potential typhoon events that would make landfalls in Shanghai (SHLD), in the north of Zhejiang (ZNLD) and moving northwards …
