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 …

The Importance Of Landscape Position Information And Elevation Uncertainty For Barrier Island Habitat Mapping And Modeling, Nicholas Matthew Enwright

LSU Doctoral Dissertations

Barrier islands provide important ecosystem services, including storm protection and erosion control to the mainland, habitat for fish and wildlife, and tourism. As a result, natural resource managers are concerned with monitoring changes to these islands and modeling future states of these environments. Landscape position, such as elevation and distance from shore, influences habitat coverage on barrier islands by regulating exposure to abiotic factors, including waves, tides, and salt spray. Geographers commonly use aerial topographic lidar data for extracting landscape position information. However, researchers rarely consider lidar elevation uncertainty when using automated processes for extracting elevation-dependent habitats from lidar data. …

Climatology And Trends In Hourly Precipitation For The Southeast United States, Vincent M. Brown, Barry D. Keim, Alan W. Black

Faculty Publications

This research introduces a climatology of hourly precipitation characteristics, investigates trends in precipitation hours (PH) and hourly accumulation, and uses four different time series to determine if precipitation intensity is changing across the southeastern United States from 1960 to 2017. Results indicate hourly intensity significantly increased at 44% (22/50) of the stations, accompanied by an increase in average hourly accumulation at 40% of the sites analyzed (20/50). The average duration of precipitation events decreased at 82% (41/50) of the stations. However, the frequency of 90th percentile hourly events and events above station-specific average hourly totals did not show a broad …

Investigation Of Spectral Variation Of Pine Needles As An Indicator Of Arsenic Content In Soils, Ji Hye Shin, Jaehyung Yu, Lei Wang, Jieun Kim, Sang Mo Koh

Faculty Publications

The spectral response to arsenic (As) stress of pine needles (Pinus densiflora Siebold and Zucc.) from an abandoned lead (Pb)–zinc (Zn) mine was investigated based on chemical and spectroscopic analyses. The correlation analysis between the content of As in needle samples and that of soils and spectral parameters of the needle samples were conducted. The results showed very high correlation between As content in pine needles and soils. The major spectral response of pine needles to the As stress were characterized by the increase in the green and red color reflectance, the decrease in the first derivatives at 1648 nm, …

The Religion Of Policing: Race, Riots, And The Killing Of Alton Sterling, Landon Jay Douglas

LSU Doctoral Dissertations

Deadly force encounters with black people and law enforcement officials are far too numerous and encounters that result in the death of civilians do not always result in disciplinary actions against officers, many of whom are white. The high-profile killings of black people in America require an in-depth analysis of race, policing, and the origins of tactics used by law enforcement against black people, which is not merely data-driven, but also theory driven. In trying to understand the disparate treatment experienced by black people at the hands of law enforcement officials, and the extent to which many Americans, mostly white …

"If They Don't Tell You, The Hair Will": Hair Narrative In Contemporary Women's Writing, Darina Pugacheva

LSU Doctoral Dissertations

The history of colonial and racial oppression made hair stories and testimonials fundamental to understanding hair as a unifying element particular for women of African descent in the post-slavery era. Seen as such, their hair narrations provide the first-person perspective of their life experiences while at the same time inviting a critical investigation of colonial and racial oppression. Contemporary women writers develop these types of narrations into a special language of hair that helps them tell a story that is not apparent or straightforward. This literary device that uses hair to uncover deeper social and political issues is bound up …

Hourly Precipitation Climatology Of The Southeast United States, Vincent Brown

LSU Doctoral Dissertations

Precipitation changes are one of the most important potential outcomes of a warming climate because of how essential it is to society and ecosystems. Sub-daily precipitation time series provide more information on precipitation characteristics, particularly frequency, intensity, and duration compared to daily data. In a series of four peer-reviewed manuscripts, this research investigates sub-daily precipitation characteristics from a climatological perspective. The first study introduces a climatology of hourly precipitation for four first-order weather stations across Louisiana, explores possible changes in the hourly precipitation distribution, and links winter Gulf of Mexico sea surface temperatures to the frequency of hours with precipitation. …

Mapping Soil Moisture From Remotely Sensed And In-Situ Data With Statistical Methods, Yaping Xu

LSU Doctoral Dissertations

Soil moisture is an important factor for accurate prediction of agricultural productivity and rainfall runoff with hydrological models. Remote sensing satellites such as Soil Moisture Active Passive (SMAP) offer synoptic views of soil moisture distribution at a regional-to-global scale. To use the soil moisture product from these satellites, however, requires a downscaling of the data from an usually large instantaneous field of view (i.e. 36 km) to the watershed analysis scales ranging from 30 m to 1 km. In addition, validation of the soil moisture products using the ground station observations without an upscaling treatment would lead to cross-level fallacy. …

Contrasting Latitudinal Gradients Of Body Size In Helminth Parasites And Their Hosts, Tad Dallas, Alyssa Lois M. Gehman, A. Alonso Aguirre, Sarah A. Budischak, John M. Drake, Maxwell J. Farrell, Ria Ghai, Shan Huang, Ignacio Morales-Castilla

Faculty Publications

© 2019 John Wiley & Sons Ltd Aim: We examined body size scaling relationships for two developmental life stages of parasitic helminths (egg and adult) separately in relationship to latitude (i.e. Bergmann's rule), temperature and temperature seasonality. Given that helminth eggs experience environmental conditions more directly, whereas adults live inside infected host individuals, we predict stronger environmentally driven gradients of body size for eggs than for adults. Location: Global. Time period: Present day. Major taxa studied: Parasitic helminths. Methods: We compiled egg size and adult body size data (both minimum and maximum) for 265 parasitic helminth species from the literature, …

Predicting Climate Types For The Continental United States Using Unsupervised Clustering Techniques, D. Sathiaraj, X. Huang, J. Chen

Faculty Publications

The problem of clustering climate data observation sites and grouping them by their climate types is considered. Machine learning–based clustering algorithms are used in analyzing climate data time series from more than 3,000 climate observation sites in the United States, with the objective of classifying climate type for regions across the United States. Understanding the climate type of a region has applications in public health, environment, actuarial science, insurance, agriculture, and engineering. In this study, daily climate data measurements for temperature and precipitation from the time period 1946–2015 have been used. The daily data observations were grouped into three derived …

A Case-Study Approach To Investigate Transmission, Co-Infection, And Clinical Sequelae During Epidemics Of Dengue And Ebola Virus Disease, Jennifer Elizabeth Giovanni

LSU Doctoral Dissertations

From within their ecologic niches, zoonotic viruses emerge from animal reservoirs into the edges and centers of human habitation to exploit opportunities for unabated transmission within immunologically–naïve populations. Our understanding of where, in whom, and how these viruses emerge is under direct challenge, driving the evolution of modern infectious disease epidemiology within a rapidly-connected global community. The studies presented herein are based on analyses of both aggregate and case-level data, which, we argue, provide unique insight into the complexities of transmission, co-infection, and clinical sequelae occurring within, and arising from, epidemics of emerging zoonotic viruses. In Chapter II, we investigate …

Authentic Csr In Professional Sport Organizations: Application Of A Theoretical Framework, Yoseph Mamo

Chapter 2 extends literature on when, why, and how professional sport organizations (PSO) can develop authentic CSR activities that can have a long-term positive impact on stakeholders. Chapter 3 advances literature on identifying the relevant dimensions of CSR that are supported by the fans rather than using a more holistic approach will advance our understanding of the relationships between different types …

A Comparison Of Hominin Teeth From Lincoln Cave, Sterkfontein L/63, And The Dinaledi Chamber, South Africa, Juliet K. Brophy, Joel Irish, Steve E. Churchill, Darryl J. De Ruiter, John Hawks, Lee R. Berger

Faculty Publications

Prior to the recovery of Homo naledi from the Dinaledi Chamber of the Rising Star Cave system, the Middle Pleistocene fossil record in Africa was particularly sparse. With the large sample size now available from Dinaledi, the opportunity exists to reassess taxonomically ambiguous teeth unearthed at the nearby site of Sterkfontein. Teeth recovered from Lincoln Cave South and area L/63 at Sterkfontein have been considered ‘most probably Homo ergaster’ and ‘perhaps Archaic Homo sapiens’, respectively. Given the similarities shared between Lincoln Cave, area L/63, and the Dinaledi Chamber with regard to climatic/geologic depositional context and age, two teeth from the …

Women Of The Edward J. Gay Family As Textile And Dress Consumers In Louisiana, 1849-1899, Lindsay Danielle Reaves

LSU Doctoral Dissertations

Economic, social, and cultural historians have studied and analyzed consumption behaviors throughout the 20^th century and into the 21^st century. Decorative household textiles and dress items are two product categories that follow the consumption process. American consumption behaviors during the introduction of mass-produced textiles and dress items throughout the 19^th century have not been well documented.

The purpose of this research is to expand the knowledge of Southern planter-class women’s consumer behavior in relation to decorative household textiles and dress items. Arnould and Thompson’s (2005) Consumer Culture Theory and Belk’s (1988) research into possessions and the extended …

Demystifying Jadeite: An Underwater Maya Discovery At Ek Way Nal, Belize, Heather Mckillop, George Harlow, April Sievert, C. Wayne Smith, Michael C. Wiemann

Faculty Publications

Jadeite artefacts at Maya sites are normally associated with ritual and ceremonial locations, with high-quality jadeite reserved for elite objects. The discovery of a jadeite gouge with a wooden handle at a Classic Maya salt-working site submerged by sea-level rise - Ek Way Nal, Belize - is therefore unexpected and provides new information about the utilitarian use of this stone. The extremely high quality of this jadeite tool is particularly surprising, offering new insight into the Classic Maya exchange systems and the role of salt makers such as those based at Ek Way Nal.

"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 …

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, …

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, …
