Ceramic Technology, Production, And Exchange As Seen Through Macroscopic Analysis Of Pottery Fragments From The Early Horizon Center Caylán, Nepeña Valley, Peru, Michelle Nicole Miller
LSU Master's Theses
In this thesis, I examine the production, use, and decoration of ceramic vessels at the Early Horizon center of Caylán (800-1 B. C. E.) on the Peruvian North Central-Coast. Pottery sherds are artifacts ubiquitously recovered at archaeological sites, especially in sedentary agrarian societies. Most studies of ceramics in Peru have focused on typological sequences. Recently investigators in the Nepeña Valley have focused on ceramic pastes and technologies. The materials examined in this thesis were excavated from Caylán. Caylán is an incipient urban center, which developed during the Early Horizon (900-200 B. C. E.). Caylán’s dense urban core consists in 43 …
Tropospheric Ozone Prediction With Land Cover Regression In Baton Rouge, Louisiana, Mallory Nance Thomas
Tropospheric Ozone Prediction With Land Cover Regression In Baton Rouge, Louisiana, Mallory Nance Thomas
LSU Master's Theses
Ground level ozone (O3) is a pollutant of great public health concern. Spatial interpolation techniques provide powerful tools in estimating O3 exposure, but many fall short when predicting O3 on complex surfaces, especially given the high local variability typically associated with O3 data. Like most other locations, the Baton Rouge, Louisiana, O3 non-attainment zone (BRNZ) is plagued by a sparse density of O3 monitoring stations. This research explores land use regression (LUR) as an alternative spatial prediction method in and around the BRNZ. Multiple years of data are used to partially compensate for the small sample of spatial points. To …

Examining Healthy Food Accessibility In Baton Rouge, Louisiana Using A Huff-Modified 2sfca Method, Xuan Kuai
LSU Master's Theses
Food accessibility refers to people’s ability to access the service of food providers. Disparities in healthy food accessibility have long been a public health concern. This study proposes a new approach modified from the popular 2-Step Floating Catchment Area (2SFCA) method to measure spatial access. By incorporating a self-adaptive kernel density function extracted from the Huff Model, the proposed new method is termed the Huff-modified 2SFCA method. It is then applied to measure the healthy food accessibility in East Baton Rouge Parish, Louisiana. The research accounts for the economically disadvantaged groups that may walk or depend on public transit for …

Habitat Preferences Of Adult Spotted Seatrout, Cynoscion Nebulosus, In Lake Pontchartrain, Louisiana, Noelle Marie Bramer
LSU Master's Theses
Spotted seatrout (Cynoscion nebulosus) are a highly sought after sportfish, making up over 90% of the recreational fishery in Louisiana. As a significant portion of every life history stage is spent within its natal estuary, it is an ideal bio-indicator of estuarine health. As one of the largest estuaries in Louisiana, Lake Pontchartrain represents one such supporting ecosystem. From November 2012 to April 2014 acoustic tagging of individual fish, a lake-wide receiver array, and ArcGIS mapping software were utilized to determine the spatial distribution of spotted seatrout within the lake. Receivers were placed in representative locations including man-made and natural …
A Study Of The Effectiveness Of A Common Household Chemical For Maceration, Sara O'Neil Wyatt
A Study Of The Effectiveness Of A Common Household Chemical For Maceration, Sara O'Neil Wyatt
LSU Master's Theses
Maceration is often a necessary component when working on a forensic case. Since it is not very common to get a case with fully skeletonized remains, the soft tissue must be removed for the forensic anthropologist to start their assessment. There are varying maceration techniques, but the goal is the same: to remove the soft tissue without damaging the bone The main purpose of my research is to examine a common household chemical, Drano® Max Gel, to determine its effectiveness for maceration. I tested two diluted solutions of Drano® Max Gel, 25% and 12.5%, both heated and unheated, to determine …

Dendrotempestology: Identifying The Statistical Relationship Between Hurricanes And Tree Growth In The Pine Savannas Of Coastal Mississippi, Clay Stephens Tucker
LSU Master's Theses
Hurricanes cause massive destruction of property and land through high wind speeds, high precipitation, and flooding from storm surge inundation. Hurricane Katrina produced nearly an 8.5 meter-high storm surge at Pass Christian, Mississippi. The envelope of high water from Hurricane Katrina covered a large area of the Gulf Coast including, but not limited to, the area from the Atchafalaya Bay in Louisiana to Mobile Bay in Alabama. This study assesses the relationship between hurricane characteristics (i.e., storm surge and maximum wind) and tree growth using coastal pine tree cores taken in Grand Bay National Estuarine Research Reserve (GBNERR). GBNERR, an …
Neodymium Isotope Ratios And A Positive Δ13c Excursion: Connecting Oceanographic And Climate Changes Near The M4-M5 Sequence Boundary Of The Late Ordovician, Zachary Wright
LSU Master's Theses
A significant positive carbon isotope excursion first described from the Guttenberg Member of the Decorah Formation in Iowa called the GICE is a defining feature of Late Ordovician chemostratigraphy. It occurs near the M4-M5 sequence boundary of the Late Ordovician and has been correlated across the globe using prominent K-bentonite ash beds and conodont biomarkers. The cause of the GICE has been debated, with some arguing that it represents the initiation of a glacial period in a greenhouse climate 10 Ma before the end Ordovician glaciation and extinction. A variety of cooling signals have been identified across the M4-M5 sequence …
Impacts Of The Three-Dimensional Oceanic Thermal Structure And Translation Speed On Tropical Cyclogenesis And Intensity Fluctuations During The 2005 North Atlantic Hurricane Season, Jordan Vick Pino
LSU Master's Theses
Tropical cyclones are some of the most devastating natural phenomena on the planet. While it has long been recognized that sea surface temperature is an important factor in the evolution of tropical cyclones, it is limited due to its two-dimensional nature. This research seeks to investigate the role of the three-dimensional oceanic thermal structure and translation speed (Uh) on the cyclogenesis and intensity fluctuations of these powerful storm systems. This investigation utilized two main data sets: (1) depth of the 26°C isotherm (D26) which indicates the depth (or volume) of the warm water layer, and (2) hourly-interpolated wind …
Nationalization And Regionalism In 1920s College Football, Bennett Jeffery Koerber
Nationalization And Regionalism In 1920s College Football, Bennett Jeffery Koerber
LSU Master's Theses
By illuminating the complexities of 1920s American society, college football serves as a remarkably insightful cultural device. At the commencement of the decade, a national business community – one that had been developing since the late nineteenth century – appeared to have come to fruition. The more connected nature of the country served to homogenize the United States economically, politically, and even socially. Citizens who had once lived autonomously found themselves more interconnected with neighboring regions of the country, and thus increasingly defined by national characteristics. This served as an internal crisis of sorts because regional identity operated as a …
Using Stormwater Modeling In Iterative Site Design: An Integration Of Techniques From Engineering And Landscape Architecture, Brooke Erin Morris
Using Stormwater Modeling In Iterative Site Design: An Integration Of Techniques From Engineering And Landscape Architecture, Brooke Erin Morris
LSU Master's Theses
Landscape Architects currently do not have an efficient method for including stormwater quantities in early stages of their design process. With stormwater control infrastructure and theory rapidly shifting in favor of stormwater management with Green Infrastructure or Low Impact Development technologies (LIDs), landscape architects and planners are increasingly making layout and sizing decisions for stormwater design. Due to the development of modeling tools, it is now possible to rapidly produce quantifiable stormwater values for complex site designs at a range of scales. This paper proposes a methodology for the utilization of the EPA – Stormwater Management Model (SWMM), in conjunction …

The Association Between Attachment And Posttraumatic Growth In A Sample Of U.S. College Students, Keith Alan Morgan
The Association Between Attachment And Posttraumatic Growth In A Sample Of U.S. College Students, Keith Alan Morgan
LSU Master's Theses
The purpose of this study is to examine the association between attachment and posttraumatic growth. Previous literature has suggested that securely attached individuals show more positive methods of coping with stress by activating their attachment system and facing the distress of a traumatic event. On the other hand, insecurely attached individuals display more negative methods of dealing with stress. Those with insecure attachment may avoid the distress of a traumatic event or not successfully activate the attachment system. Thus, it is expected that securely attached individuals will demonstrate higher levels of posttraumatic growth, or positive reactions to the experience of …
Decomposition And Entomological Associations Of Swine In Louisiana Micro-Environments, Rachael Ann Farris
Decomposition And Entomological Associations Of Swine In Louisiana Micro-Environments, Rachael Ann Farris
LSU Master's Theses
Flies are commonly used as forensic indicators of an approximate time of death. This measurement of postmortem interval is influenced by factors such as climate and the environment in which the remains are placed. Each environment has its own set of influences that can accelerate or hinder the rate of decomposition. Remains left on dry land will decompose at a faster rate than remains in water due to the accessibility of the remains to scavengers and necrophagus insects. This research serves to provide a start to research into decomposition in the swamp environment of southern Louisiana. Three fetal pigs were …
