Morphologic Adjustments Of Actively Evolving Highly Curved Neck Cutoffs, Derek Richards, Kory Konsoer Dec 2019

Morphologic Adjustments Of Actively Evolving Highly Curved Neck Cutoffs, Derek Richards, Kory Konsoer

Faculty Publications

Neck cutoffs and their resultant oxbow lakes are important and prominent features of riverine landscapes. Detailed field-based research focusing on the morphologic evolution of neck cutoffs is currently insufficient to fully characterize cutoff evolution. High-resolution bathymetric data were collected over 3 years for the purpose of determining channel morphology and morphologic change on three actively evolving neck cutoffs. Results indicate the following general trends in morphologic adjustment: (1) a longitudinal bar in the upstream meander limb that develops near the entrance to the abandoned bend; (2) a deep scour hole in the downstream meander limb immediately downstream of the cutoff …

emperatures (SST), salinity, carbonate chemistry, and acidity. Over the last half-century, some reef communities have been disappearing at an alarming pace. This study focuses on the Gulf of Mexico, where the majority of shallow coral reefs are reported to be in poor or fair condition. We analyze the RCP8.5 ensemble of the Community Earth System Model v1.2 to identify monthly-to-decadal trends in Gulf of Mexico SST. Secondly, we examine projected changes in ocean pH, carbonate saturation state, and salinity in the same coupled model simulations. We find that the joint impacts of predicted higher temperatures and changes in ocean acidification …


Race, Geography, And News Coverage Of The Opioid Epidemic, Nicholas B. Robert Nov 2019

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 Nov 2019

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.


Social Justice Through Social Media: The Use Of Twitter As A Tool For Activism In The #Metoo #Blacklivesmatter Era, Laura L. Coleman Nov 2019

Social Justice Through Social Media: The Use Of Twitter As A Tool For Activism In The #Metoo #Blacklivesmatter Era, Laura L. Coleman

LSU Master's Theses

This study focuses on social justice and how people on Twitter chose to talk about it. The rise of social media has allowed Twitter users to speak more freely in more spaces than one. The study compared two different sexual assault cases between Judge Brett Kavanaugh and Professor Christine Blasey; and Virginia’s Lt. Governor Justin Fairfax and Vanessa Tyson. Applying the social responsibility theory, which allows free press without any censorship, I then can see the tone of which Black Twitter users have when talking about two separate sexual assault cases. This study compares the use of the #BlackTwitter hashtag …

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 …

The Impact Of Experimentally-Induced Perceived Discrimination On Substance Use, Kimberlye Elise Dean Nov 2019

The Impact Of Experimentally-Induced Perceived Discrimination On Substance Use, Kimberlye Elise Dean

LSU Doctoral Dissertations

Substance use disorders (SUDs) are among the most debilitating psychiatric disorders. Although prevalence rates of SUDs are similar between White and Black adults, these groups experience differential treatment outcomes (e.g., Black adults with SUDs are more likely to report greater pre- and post-treatment substance use). Examining culture-specific correlates of racial differences in substance use is vital to improve understanding of the etiological and maintaining mechanisms of SUDs among Black adults. Perceived racial discrimination (PRD) is prospectively related to various substance use-related outcomes. Thus, some may use substances to alleviate psychological distress (e.g., anxiety) associated with PRD, which may over time …

Validation Of The Dual-Factor Model Of Mental Health In College Students: An Investigation Of Group Characteristics, Ashley Perle Galsky Oct 2019

Validation Of The Dual-Factor Model Of Mental Health In College Students: An Investigation Of Group Characteristics, Ashley Perle Galsky

LSU Doctoral Dissertations

The dual-factor model of mental health proposes that symptoms of mental illness and markers of mental wellness can occur simultaneously, while functioning as discrete factors that contribute to mental health and adaptive functioning (Keyes, 2005). The current study investigated the utility of the dual-factor model of mental health (cf. Greenspoon & Saklofske, 2001; Suldo & Shaffer, 2008; Suldo, Thalji, & Ferron, 2011) in college students (N = 1,023). Using self-reported symptoms of depression, anxiety, stress, inattention, and hyperactivity/impulsivity as indicators of psychopathology, in combination with self-reported subjective well-being (SWB) as an indicator of wellness, participants were classified into one …

A Longitudinal Study Of Two Teacher-Report Screening Measures For Student Mental Health: Comparing The Swtrs And Saebrs, Anthony Joseph Roberson Oct 2019

A Longitudinal Study Of Two Teacher-Report Screening Measures For Student Mental Health: Comparing The Swtrs And Saebrs, Anthony Joseph Roberson

LSU Doctoral Dissertations

This study compared the comparative utility of two teacher-report universal screeners for student mental health, the Student Wellbeing Teacher-Report Scale (SWTRS) and the Social, Academic, and Emotional Behavior Risk Screener (SAEBRS), across two occasions during the school year. Both instruments measure aspects of academic, social, and emotional student behavior from the teacher’s perspective but differ in their inclusion of both positive and challenging behaviors (i.e., SAEBRS) or positive behaviors only (i.e., SWTRS). Results suggest that both have strong concurrent and predictive validity characteristics in identifying student risk but differ in which outcomes they are better at predicting.

Pacts 1.0: A Crowdsourced Reporting Standard For Paleoclimate Data, Kristine Delong

Faculty Publications

The progress of science is tied to the standardization of measurements, instruments, and data. This is especially true in the Big Data age, where analyzing large data volumes critically hinges on the data being standardized. Accordingly, the lack of community-sanctioned data standards in paleoclimatology has largely precluded the benefits of Big Data advances in the field. Building upon recent efforts to standardize the format and terminology of paleoclimate data, this article describes the Paleoclimate Community reporTing Standard (PaCTS), a crowdsourced reporting standard for such data. PaCTS captures which information should be included when reporting paleoclimate data, with the goal of …

Social Determinants Of Health Inequality: Predictors Of Hiv Transmission Among African Americans In The Deep South, Kayla Allison Sep 2019

Social Determinants Of Health Inequality: Predictors Of Hiv Transmission Among African Americans In The Deep South, Kayla Allison

LSU Doctoral Dissertations

HIV/AIDS has become an epidemic in Black communities in the Deep South, which poses a major public health crisis. Unfortunately, the lack of attention from health officials has resulted in African Americans experiencing the greatest burden of the disease as compared to any other racial/ethnic group. Thus, this cross-sectional, correlational study examined predictors of HIV transmission with an emphasis on the course of the disease among African Americans in the Deep South region of the United States given the legacy of slavery, historical racism, and plight of African Americans in this geographical area. The institution of slavery was not isolated …


Derivational Development: Derivational Word Processing In Three English-Speaking Populations, Lisa Suzanne Kemp Sep 2019

Derivational Development: Derivational Word Processing In Three English-Speaking Populations, Lisa Suzanne Kemp

LSU Doctoral Dissertations

Native-English speaking adults use morphological decomposition to understand complex words (e.g. farmer becomes farm-er). Whether decomposition is driven by semantic organization is still unclear. It is also unclear whether ESL adults and elementary age children use the same word processing strategies as native speaking adults. This study tested an identical experimental procedure across three English-speaking populations: native speaking adults, non-native speaking adults and elementary age children. The first task tested how readers use base and suffix information in complex words and nonwords when the word featured only a base word, only a suffix, both a base and …

Addressing Racial Disparities In Parent Training Enrollment: An Examination Of Help-Seeking For Child Behavior Problems Among African American Mothers, Kasia Plessy

LSU Doctoral Dissertations

The consideration of African American mothers’ mental health help-seeking attitudes and intentionsis important when developing culturally sensitive parent training programs and potentially help bridge a critical knowledge and service gap for this population. The purpose of this study is to examine the parental help-seeking for child externalizing behavior problems in order to delineate variables that might influence BPT enrollment among African American families. To address the lack of research considering cultural factors, this study examines the influence of racial group identification, cultural childrearing values, and mental health stigmatization on African American mothers’ problem recognition and willingness to engage in behavioral …


Deciphering Public Transit Ridership In Baton Rouge: Spatial Disaggregation Approaches, Xuan Kuai Aug 2019

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 …


Life Satisfaction And Healthcare Utilization Among Immigrants To The United States, Merritt Christian Rachel Harrelson Aug 2019

Life Satisfaction And Healthcare Utilization Among Immigrants To The United States, Merritt Christian Rachel Harrelson

LSU Master's Theses

Previous research suggests a relationship between life satisfaction and healthcare utilization or HCU (Habibov & Afandi, 2016; Kim, Park, Sun, Smith, & Peterson, 2014). However, no study was found that examined this relationship among elderly American immigrants. The purpose of this study was to determine whether life satisfaction is linked to HCU for this population. The researcher of the current study applied binary logistic regression to data taken from the Health and Retirement Survey to determine whether changes in life satisfaction could be linked to variance in HCU across seven domains, including hospitalization, overnight nursing home stays, doctors visits, dentist …


The Importance Of Landscape Position Information And Elevation Uncertainty For Barrier Island Habitat Mapping And Modeling, Nicholas Matthew Enwright Aug 2019

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. …


Examining The Mechanisms Of Religious Ecology On Population Health And Material Well-Being, Joseph Andrew Clark Aug 2019

Examining The Mechanisms Of Religious Ecology On Population Health And Material Well-Being, Joseph Andrew Clark

LSU Doctoral Dissertations

A growing body of research has addressed the relationship between community-level religious environments and important aspects of well-being, such as mortality, crime, and social mobility. This research argues that the prevalence of specific religious traditions shapes these important outcomes through a variety of mechanisms. While there is no shortage of mechanisms proposed by authors - such as local attitudes towards public institutions, gender norms, and social networks - these mechanisms remain themselves untested. A notable critique of this literature suggests that without evidence supporting the existence of these mechanisms as described, scholars involved in this research run the risk of …


Attention As A Mechanism For Object-Object Binding In Complex Scenes, Kacie Mennie Jul 2019

Attention As A Mechanism For Object-Object Binding In Complex Scenes, Kacie Mennie

LSU Doctoral Dissertations

The current study attempted to determine whether direct binding between objects in complex scenes occurs as a function of directed attention at encoding. In Experiment 1, participants viewed objects in one of these different types contexts: unique scenes, similar scenes, or arrays with no contextual information. Critically, only half of the objects were attended for each encoding trial. Participants then completed an associative recognition task on pairs of items created from the previously studied scenes. Test pairs consisted of two attended or unattended objects, and were associated with a unique scene, a similar scene, or an array. Evidence of binding …
