The Siltcatcher: A Sediment-Capture System For Wetland Creation And Coastal Protection In Western Lake Pontchartrain, Andrew M. Wright

LSU Master's Theses

The West Lake Pontchartrain region faces a number of long-term environmental challenges due to anthropogenic climate disturbance and landscape modification, including sea level rise, increased storm surge risk, shoreline erosion, and wetland degradation. In response, this thesis applies recent research in the fields of landscape architecture and civil engineering to propose a dynamic, natural-systems solution for wetland creation and shoreline protection. The project envisions a series of breakwater-like structures in western Lake Pontchartrain positioned to slow water released from the nearby Bonnet Carré Spillway, causing suspended sediment to settle and create self-building and self-sustaining wetlands capable of keeping pace with …

Automatic Features Extraction From Time Series Of Passive Microwave Images For Snowmelt Detection Using Deep-Learning – A Bidirectional Long-Short Term Memory Autoencoder (Bi-Lstm-Ae) Approach., Bienvenu Sedin Massamba

LSU Master's Theses

The Antarctic surface snowmelt is prone to the polar climate and is common in its coastal regions. With about 90 percent of the planet's glaciers, if all of the Antarctica glaciers melted, sea levels will rise about 58 meters around the planet. The development of an effective automated ice-sheet snowmelt monitoring system is therefore crucial.

Microwave remote sensing instruments, on the one hand, are very sensitive to snowmelt and can see day and night through clouds, allowing us to distinguish melting from dry snow and to better understand when, where, and for how long melting has taken place. On the …

Night Of The Witch: Alternative Spirituality, Identity And Media, Andreana Tarleton

LSU Master's Theses

This thesis works to understand the relationships witches and conjurors have with the film and television depictions of them. Employing the method of film critique, I argue that the witch stands as a cultural symbol in the US of women and femmes with power, and that their stories serve as lessons to these populations about what it means to be an acceptable woman or femme, while simultaneously creating and perpetuating stereotypes of magic practitioners. Then, using the combination of hashtag ethnography, in-person and video interviewing and internet surveys, I argue that #witchblr and #witchesofcolor, as well as the space of …

Estimation Of Age From The Auricular Surface Of The Ilium Through The Utilization Of 3d Scanning And Gis, Krista Bennett

LSU Master's Theses

The ability to produce age estimations for adult skeletons has been a focus of forensic anthropologists for decades. Most age estimation methods for adult remains provide age ranges that are too narrow, too broad, or too vague. This project sought to combine 3D scans with GIS to produce morphological maps of the auricular surface of the os coxa in order to identify quantifiable characteristics for age assessment that could be used for generating narrower age range estimates for older adult remains.

A NextEngine ™ HD Desktop 3D scanner was used to scan the auricular surfaces of 384 os coxae from …

Not All Fun And Gaymes: Technology, Transgression, And Representation Among Gaymers, Kyle Bikowski

LSU Master's Theses

Over the past decade, a new identity has emerged within gaming and gay communities. This identity, Gaymer (Gay-gamer), incorporates elements from both gaming and gay communities, but is accepted by neither. This thesis asks how the interplay of actual and virtual worlds have shaped Gaymer identities, and further asks what the relationship between Gaymers and both the gay and gaming communities are; what elements are conducive to the formation of Gaymer communities; how Gaymers work with or around affordances to assert their identities in virtual and actual spaces; and to what degree representation, either within games as playable characters or …

Comparing The Accuracy Of Close-Range Photogrammetry To Microct Scanning Via Surface Deviation Analysis Of 3d Digital Models Of Hominin Molars, Margaret J. Furtner

LSU Master's Theses

The purpose of this study is to assess whether close-range photogrammetry is a viable alternative to microCT scanning for the construction of 3D models of isolated teeth. Photogrammetric scanning is more cost-effective and less time-consuming than CT scanning, and in paleoanthropological contexts eliminates the possibility of exposing fossils to doses of radiation that affect ESR dating. Samples of fossil (Homo naledi), archaeological, and contemporary human molars were scanned via microCT scanning and close-range photogrammetric scanning. The photogrammetric scans included 96 digital images per tooth which were used to construct a 3D triangular mesh. The resulting models of the tooth crowns …

Applications Of Unmanned Aerial Vehicles For Conducting Mesocarnivore And Breeding Waterfowl Surveys In Southern Manitoba, Jacob Bushaw

LSU Master's Theses

Unmanned aerial vehicles (UAVs) are becoming an increasingly important tool for wildlife surveys and equipping UAVs with thermal imaging cameras could make these surveys even more effective. In my thesis I examined the feasibility of using a UAV equipped with a thermal imaging camera to conduct mesocarnivore surveys, search for duck nests built over water, and conduct duck brood surveys in southern Manitoba.

For my first objective, I conducted nighttime mesocarnivore surveys with the UAV and thermal camera. I used a modified point-count survey from six waypoints and surveyed 29.5 ha in each replicate. I conducted a total of 200 …

The two goals of this research are to apply accessibility estimation methods to HIV testing facilities, and to examine the accessibility of HIV testing facilities in the BR MSA. To achieve these goals, this study uses several research methods. The data about HIV testing providers and their locations were collected through Internet searches. By means of a fieldwork, the data were checked, revealing that …

Changing Geographies Of Flood Mitigation Policies: A Case Study Of Central, Louisiana, Ria Mukerji

LSU Master's Theses

In 2016, the Baton Rouge region experienced what would come to be record-setting precipitation levels. The 1,000 year rainfall event dumped almost triple the amount of water on Louisiana than was seen during Hurricane Katrina (some areas received over 10 inches of rain in a matter of hours), with rain persisting from August 12^th until the 17^th. Previously a part of Baton Rouge, Central is a relatively new development that expanded into the 100 year floodplain in 2005. This thesis will present the changing geographies of flood mitigation policies since a major flood in 1983 to the …

Contextual Adjustment Of The Ite Trip Generation Rates Using Wi-Fi And Bluetooth Technologies, Saba Doulabi

LSU Master's Theses

The ITE Trip Generation Handbook has been in common use for about half a century to estimate vehicle trips generated by more than 172 land use categories as a function of establishment size (floor area) only. However, observed trip rates display a huge error range across different sites. Although contextual adjustment factors can ameliorate the error in the ITE trip generation estimates considerably, local site-specific trip generation rates should be collected for this purpose. Due to the huge time and monetary costs of data collection, adjusting the ITE trip generation rate is ignored by many jurisdictions. The primary contribution of …

Retrospective Study Of Fmol Health System Utilization Using Geospatial Information, Deekshith Mandala

LSU Master's Theses

Medicaid Expansion and closing of Emergency Departments (ED) like Earl K. Long, Baton Rouge General Mid-City ED, and Champion Medical Center changed the health care landscape in East Baton Rouge Parish (EBRP). In this research study, a Geographical Information System (GIS) is used to analyze the impact of the expansion of Medicaid and the inauguration of Our Lady of the Lake North Baton Rouge ED (OLOL NBR ED) over the utilization of Franciscan Missionaries of our Lady Health System (FMOLHS) for both emergency and non-emergency health care services. This study is performed across the 58 neighborhoods of EBRP. Overutilization of …

Spatial And Topological Analysis Of Urban Land Cover Structure In New Orleans Using Multispectral Aerial Image And Lidar Data, Shuxian Liu

LSU Master's Theses

Urban land use and land cover (LULC) mapping has been one of the major applications in remote sensing of the urban environment. Land cover refers to the biophysical materials at the surface of the earth (i.e. grass, trees, soils, concrete, water), while land use indicates the socio-economic function of the land (i.e., residential, industrial, commercial land uses). This study addresses the technical issue of how to computationally infer urban land use types based on the urban land cover structures from remote sensing data. In this research, a multispectral aerial image and high-resolution LiDAR topographic data have been integrated to investigate …

Race, Geography, And News Coverage Of The Opioid Epidemic, Nicholas B. Robert

LSU Master's Theses

The opioid epidemic is the deadliest drug epidemic in United States history. During the early stages of the epidemic, the focus was on white victims in rural and suburban areas. Using the geo-ethnic framework developed from immigration research, this study examines if geography and race impacted the framing of the opioid epidemic in newspapers. The study finds there to be a low level of geo-ethnic influenced framing in news coverage of the opioid epidemic from 2016-2018.

The Effects Of Forced Migration On The Houma Of Louisiana, Jessica R. Parfait

LSU Master's Theses

This thesis seeks to understand the effects of multiple forced migrations on the Indigenous Houma of southern Louisiana. The causes of these migrations have taken many forms such as the dispossession of land and relocating for access to resources. Through ethnographic interviews and historic research, I seek to critically engage the past to understand how it has molded the present and the lives of tribal citizens. I evaluate the power dynamics enacted upon the Houma who have recorded contact with Europeans dating to 1686 but have never been recognized as a sovereign entity by the United States.

L'Apport Des Écrivains Catholiques Du Début Du Xxe Siècle Au Roman D'Analyse À Travers Leur Étude Du Mariage, Edouard D'Espalungue D'Arros

LSU Master's Theses

The psychological novel (roman d’analyse) as a genre starts in France with Mme de Lafayette (1634-1693) in the seventeenth century with the publication of La Princesse de Clèves (1678). However, the use of a psychological perspective is less known among early twentiethth century catholic authors. At the beginning of the century, several authors have used this genre extensively to convey their moral message: Paul Bourget (1852-1935); Henry Bordeaux (1870-1963); and Émile Baumann (1868-1941). The works of these writers have not been the object of research when it comes to analyzing their views and their accounts of their epoch. …

Searching For Galveztown: Employing Multiple Methodologies To Identify Features Of The Galveztown Settlement, Ashlee Taylor

LSU Master's Theses

Galveztown (1778-1806) was a Spanish fort and settlement located in southeastern Louisiana. This site was historically important as it provided protection for the city of New Orleans during a time of constantly shifting geopolitical environment. Today, this site is among the most important historical archaeological sites in Louisiana. Culturally, this site is significant as the descendants of the settlers still live within the Baton Rouge metropolitan area. Archaeologically, the site is significant due to the limited disturbance and lack of urban development at the location which has protected the archaeological record.

Galveztown is also one of the best documented Canary …

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 …

This paper delves into Việt Nam’s socioeconomic development through Mekong agriculture, as well as …

Assessment Of Barrier Island Restoration Planning And Management In The Terrebonne Basin, Louisiana, Sean Russell Williams

LSU Master's Theses

Louisiana holds the majority of the contiguous United States’ coastal wetlands by area, providing significant benefits to users in the form of ecosystem services. Climate change, relative sea level rise, and coastal sediment budget deficits among other anthropogenic processes impact the resilience and sustainability of Louisiana’s coastal systems. Since the implementation of the Coastal Wetland Planning, Protection and Restoration Act (CWPPRA) to restore coastal wetlands in the United States, multiple barrier island restoration projects have taken place in the greater Terrebonne Basin. Amassing a catalog of case studies elucidates the social, ecological, and economic frameworks behind barrier island restoration and …

The Corridor Des Arts, Kade M. Jones

LSU Master's Theses

Arnaudville is a small rural town in south central Louisiana with a population of 1200. In 2010, the National Endowment of the Arts (NEA) named Arnaudville as one of fourteen cities that were classified as a successful case study of “Creative Placemaking.” The NEA defines creative placemaking as community partnerships that use arts and culture to shape the social, environmental, and economic identity of a place. The NUNU Arts and Culture Collective, a Louisiana Cajun French non-profit arts organization centered in Arnaudville, is the main catalyst of this effort.

Members of NUNU have identified five other rural towns within close …

"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 …

Effects Of Oil And Gas Development On Waterfowl Nesting Ecology In The Bakken Formation Of North Dakota, Cassandra G. Skaggs

LSU Master's Theses

The Prairie Pothole Region (PPR) is one of the most important areas on the continent for grassland-nesting birds. Thirty percent of the PPR overlaps the Bakken shale formation where rapidly accelerating oil and gas development has the potential to impact millions of breeding waterfowl. While oil and gas development has negatively affected other ground-nesting birds such as sagebrush passerines and Greater Sage-Grouse (Centrocercus urophasianus) in Wyoming, the potential impact on breeding waterfowl in the PPR is unknown. In addition, the PPR landscape is already heavily fragmented by agriculture, and increasing land conversion and disturbance from petroleum extraction may further …

Sacroiliac Joint Fusion In Nulliparous And Parous Females And Males, Meredith Aulds

LSU Master's Theses

Previous research shows that sacroiliac (SI) joint fusion is age and sex dependent. Older individuals—specifically starting in the fifth or sixth decade of life—are more likely to develop SI fusion. Females have a lower frequency of SI joint fusion than males, perhaps due to pregnancy or parturition. This study examines the relationship between SI joint fusion with both sex and parity status in females. The issue is whether the prevalence of SI fusion in nulliparous females is more similar to that of males or parous females. The sample consists of 46 nulliparous females, 119 parous females, and 158 males from …

"Sir, I Cannot Entertain You": Tour Guides As Agents Of Truth And Transformation At The Whitney Plantation, Sarah Latham

LSU Master's Theses

According to the Louisiana office of tourism, one out of every nine workers in Louisiana relies on the state’s tourism industry for their wages, of which plantation tourism is a growing part (2016). This research examines the experiences of tour guides at the Whitney Plantation. How do tourists’ expectations and concepts of heritage affect the way tour guides do their jobs? What are tour guides’ experiences of being objectified by visitors? How are tour guides’ experiences shaped by race and racialized expectation? Specifically, I examined tour guides at The Whitney Plantation Museum in Wallace, Louisiana. This project drew on participant-observation …

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 …

Estimating Sex Using The Human Mandibular Canine, Brittney Blevins

LSU Master's Theses

Sexual dimorphism can be quantified in human mandibular canines; therefore, these teeth can be used to estimate sex of skeletonized individuals. This study complements and expands previous research by comparing mesiodistal diameter (MD), buccolingual diameter (BL), and crown area of human mandibular canines. Measurements were taken from a sample of skeletal individuals from the Terry Collection (n=677), the Maxwell Museum of Anthropology Skeletal Collection (n=86), and a random sample of dental casts from the James K. Economides Orthodontic Case File (JKE, n=624), for a total study sample of 741 males and 677 females. Both left and right canines were measured, …

Using Entheseal Length To Infer Locomotor Type, Antonio R. Otero

LSU Master's Theses

An enthesis is a marking (tuberosity or impression) on bone where a muscle or tendon attaches and it can be influenced by age, sex, physical activity, and muscle size. This study ascertains whether entheses, long bones, and their respective ratios can be used as an indicator for mode of locomotion in four primate species: Ateles geoffroyi (Geoffroy’s spider monkey), Colobus guereza (mantled guereza), Hylobates lar (lar gibbon), and Macaca mulatta (rhesus monkey). Seven entheses on four long bones were chosen based on importance of the muscle in relation to specific locomotor types, use in other studies, and …

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 …
