Reconsidering The Obstetrical Dilemma: Correlations Between Head And Pelvic Size, Kelsey Catrice Fox

LSU Master's Theses

The Obstetrical Dilemma (OD) theory has become canon in biological anthropology. The OD posits that i] dystocia results from bipedal mothers and encephalized infants, ii] contrasting selection for bipedality and obstetrics hinders locomotive efficiency, and iii] the contradicting requirement of the fetus being small enough to pass through the birth canal yet being cognitively advanced enough to cling to its mother after birth. Females, theoretically, exhibit deficient gait efficiency for the sake of successful childbirth. An obstetric advantage theory has been posited where taller individuals with a larger head size have larger pelves. If the distance between the acetabulae increases …

Spatial Production And Nomadic Subjectivities In A Buddhist Learning Space, Chau Bao Le

LSU Doctoral Dissertations

Space and place are an integral part in the geographies of education, therefore, knowledge about culturally complex and ethnically diverse transnational communities could inform curricular innovations that meet the needs of individual students. This year-long ethnographic study challenged the prevailing realities that U.S. schools continue to devalue the experiences and cultural backgrounds of immigrant youth, which caused students from ethnic, cultural, racial, linguistic, and religious minority groups to feel structurally excluded and marginalized. Through examining the spatial production and nomadic subjectivities enacted over time in a transnational, diasporic space of a Buddhist temple in a U.S. southern state, the study …

The analytical sample included 2845 children aged 9-11 years from the International Study of Childhood Obesity, Lifestyle and the Environment. Multilevel generalized linear mixed models were used to estimate the associations between distance, safety and socioeconomic variables, and the …

Evaluating Temporal Approximation Methods Using Burglary Data, Lukas Oswald, Michael Leitner

Faculty Publications

Law enforcement is very interested in knowing when a crime has happened. Unfortunately, the occurrence time of a crime is often not exactly known. In such circumstances, estimating the most likely time that a crime has happened is crucial for spatio-temporal analysis. The main purpose of this research is to introduce two novel temporal approximation methods, termed retrospective temporal analysis (RTA) and extended retrospective temporal analysis (RTAext). Both methods are compared to six existing temporal approximation methods and subsequently evaluated in order to identify the method that can most accurately estimate the occurrence time of crimes. This research is conducted …

Spatial Synchrony Is Related To Environmental Change In Finnish Moth Communities: Synchrony And Environmental Change, Tad A. Dallas, Laura H. Antão, Juha Pöyry, Reima Leinonen, Otso Ovaskainen

Faculty Publications

© 2020 The Author(s). Spatially distinct pairs of sites may have similarly fluctuating population dynamics across large geographical distances, a phenomenon called spatial synchrony. However, species rarely exist in isolation, but rather as members of interactive communities, linked with other communities through dispersal (i.e. a metacommunity). Using data on Finnish moth communities sampled across 65 sites for 20 years, we examine the complex synchronous/anti-synchronous relationships among sites using the geography of synchrony framework. We relate site-level synchrony to mean and temporal variation in climatic data, finding that colder and drier sites-and those with the most drastic temperature increases-are important for …

Documenting Desire: Addressing The Educational Needs Of Undocumented English Learners, Alejandra Sofia Torres

LSU Doctoral Dissertations

While research on motivation in second language acquisition is copious and the interest in undocumented youth within the education field is growing, there is a need to closely examine the intersection of being both undocumented and an English Learner (EL) and how this intersection often limits ELs, especially those in underserved schools. Using ethnographic methods, this dissertation documents the educational experiences of thirty-one Spanish-speaking ELs in a predominately of color, urban, working-class high school in the southeastern United States. EL participants were ages fourteen through twenty with varying non-citizen immigrant statuses. Semi-structured interviews and field notes were collected during the …

Geography and associated hydrological, hydroclimate and land-use conditions and their changes determine the states and dynamics of wetlands and their ecosystem services. The influences of these controls are not limited to just the local scale of each individual wetland but extend over larger landscape areas that integrate multiple wetlands and their total hydrological catchment-the wetlandscape. However, the data and knowledge of conditions and changes over entire wetlandscapes are still scarce, limiting the capacity to accurately understand and manage critical wetland ecosystems and their services under global change. We present a new Wetlandscape Change Information Database (WetCID), consisting of geographic, hydrological, …

The Strange Death Of American Democracy: Judicial Supremacy And The New Constitutional Politics, 1910-1916, Logan Istre

LSU Master's Theses

American constitutional politics reached a crisis point during the Progressive Era. At the center of the crisis was the question as to what the Constitution meant and who had the final word in interpreting it: The Supreme Court or the People of the United States. That fundamental question came to a head in the presidential election of 1912. The result of that contest was the confirmation of judicial supremacy in constitutional interpretation and a mortal blow the nation’s traditional popular constitutional politics. The ensuring consensus of judicial supremacy has defined the nation’s constitutional politics since, which has resulted in the …

Quantifying The Individual Contributions Of Climate Change, Dam Construction, And Land Use/Land Cover Change To Hydrological Drought In A Marshy River, Peng Qi, Y. Jun Xu, Guodong Wang

Faculty Publications

Hydrological drought for marshy rivers is poorly characterized and understood. Our inability to quantify hydrological drought in marshy river environments stems from the lack of understanding how wetland loss in a river basin could potentially change watershed structure, attenuation, storage, and flow characteristics. In this study, hydrological drought in a marshy river in far Northeast China at a higher latitude was assessed with a streamflow drought index (SDI). A deterministic, lumped, and conceptual Rainfall-Runoff model, the NAM (Nedbor Afstromnings Model), was used to quantify the individual contributions of climate change, land use/land cover (LULC) change, and river engineering to hydrological …

Baton Rouge Slam!: An Obituary For Summer 2016: A Critical Performance Ethnography Of Eclectic Truth Poetry Slam, Joshua Hamzehee

LSU Doctoral Dissertations

This critical performance ethnography presents the theory, methodology, and practice surrounding the fieldwork, scripting, and performance of Baton Rouge SLAM!: An Obituary for Summer 2016. As participant-observer, director, and co-performer, I unpack social drama, performance ethnography, and slam culture by employing a lens rooted in critical race theory. Local poets permitted me to de- and re-contextualize their interviews into ensemble scenes and theatricalize their slam poems about the recent summer’s charged events. One year later, this involved and embodied process of ethnographic bricolage became the ensemble cast performance of Baton Rouge SLAM!: An Obituary for Summer 2016. Community members and …

Water, Waste, And Race: Designing For Change On The Shelby County Landfill, Elizabeth Peterson

LSU Master's Theses

Historically, landfills have been viewed through an environmental lens as sites for technical remediation, employing scientific or engineering strategies for testing, mitigation and capping. They are more rarely viewed as cultural landscapes, places with histories of habitation and use, or as potential sites for design. This thesis investigation examines the Shelby County Landfill in Memphis, Tennessee from a cultural landscape perspective, opening up a dialog and opportunity to think about this site and other waste sites in a more layered and culturally rich way.

This research contributes to discussions within the field of landscape architecture that present waste landscapes as …

Analyzing Climate Risk To Maritime Cypress Swamps And Pine Savannas Of The Gulf Of Mexico Coastal Plain, Clay Stephens Tucker

LSU Doctoral Dissertations

As sea levels rise, coastal trees are increasingly stressed by saltwater inundation, and stressed trees are ideal for studying changes in the environment through time. Dendrochronology has been used for more than a century to explain changes in past environments using tree rings. Using ring widths and stable isotopes from coastal trees, the effects of tropical cyclones and freshwater moisture availability are shown in regard to tree growth and ultimately are discussed in terms of change to the environment as a whole. Changes in tree growth as they relate to various climate parameters are measured using superposed epoch analysis, moving-window …

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 …

An Atmospheric And Spatiotemporal Examination Of Lightning-Initiated Terrestrial Gamma-Ray Flashes Detected By The Fermi Satellite And Tetra Ii, Deirdre Colleen Smith

LSU Doctoral Dissertations

Terrestrial Gamma-ray Flashes (TGFs) are sub-millisecond bursts of the highest naturally occurring light-energy found within Earth’s atmosphere. TGFs are associated with the electric fields produced in thunderstorms and are geolocated by coincident sferics from lightning strokes. Though billions of lightning strokes occur globally each year, fewer than 1,000 TGFs are detected via satellite and ground-based sensors and only a small fraction are geolocated via sferics.

To date, few studies have focused on individual thunderstorms and climates that produce TGFs. This dissertation examines TGFs from two differing data samples: 1) NASA's Fermi Gamma-Ray Burst Monitor (2013-2018) and 2) The TGF and …

A Case Study Of Two Preservice Elementary Music Teachers As Culture-Bearers, Julius Kyakuwa

LSU Doctoral Dissertations

The integration of music from unfamiliar cultures in music classrooms is part of education curriculums around the world. International music education organizations also have goals for using a variety of musics in music education programs as one way of educating students to meet the 21st century global education targets. In the American education practice, the concept and principles of multiculturalism have been prominent in classroom subjects for over 50 years. In music education, multicultural approaches continue to be included in music standards and curriculum guides across the United States. Music educators, likewise, often use culture-bearers to expose their students to …

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 …

Anomalous Oceanic Conditions In The Central And Eastern North Pacific Ocean During The 2014 Hurricane Season And Relationships To Three Major Hurricanes, Victoria L. Ford, Nan D. Walker, Iam Fei Pun

Faculty Publications

The 2014 Northeast Pacific hurricane season was highly active, with above-average intensity and frequency events, and a rare landfalling Hawaiian hurricane. We show that the anomalous northern extent of sea surface temperatures and anomalous vertical extent of upper ocean heat content above 26 °C throughout the Northeast and Central Pacific Ocean may have influenced three long-lived tropical cyclones in July and August. Using a variety of satellite-observed and-derived products, we assess genesis conditions, along-track intensity, and basin-wide anomalous upper ocean heat content during Hurricanes Genevieve, Iselle, and Julio. The anomalously northern surface position of the 26 °C isotherm beyond 30° …
