Investigating Preferences And Behavior Within Environmental Economics, Sapana Bastola

LSU Doctoral Dissertations

To respond to the environmental problems posed by disposable plastic bags, several mechanisms exist, such as bag taxes and bans, but such policies are infeasible in several U.S. states and municipalities. This study uses a social quasi-experiment to examine the effect of a voluntary token-donation program, which reduces disposable plastic bag use by providing a small charitable donation incentive. We find that the token-donation program reduces the probability of disposable bag use by 11.4–12.9 percentage points, representing about a 30%–34% decrease in bag use. Our results demonstrate effective mechanisms to reduce plastic bags exist without government-mandated policy.

Despite the widespread …

Longitudinal Associations Between Housing Instability, Primary Caregiver's Mental Health, Parenting Skills, And Child Behavior Problems: A Latent Growth Modeling Approach, Xi Du

LSU Doctoral Dissertations

Children who grow up in disruptive environments have heightened vulnerability to psychological and behavioral difficulties, which may influence overall well-being through the course of their lives. This study combined a life course perspective with Conger’s family stress model to investigate the longitudinal associations between housing instability, primary caregiver’s mental health, parenting skills, and child internalizing/externalizing behavior problems by unpacking dynamic change from a focal child’s early childhood to adolescence in each factor.

Data came from the Panel Study of Income Dynamics and its Child Development Supplement survey. The analytic sample comprises 783 children who aged 3-7 at enrollment with consistent …

Creating A Public Space For Georeferencing Sanborn Maps: A Louisiana Case Study, Adam Cox

LSU Master's Theses

As institutional archives digitize their historical map collections and make them publicly available online, new methods for engaging with these materials emerge. Georeferencing the maps transforms their content from static images to dynamic map overlays, and allows for the extraction of geographic data like building footprints or place name coordinates. Many organizations have turned to crowdsourcing to georeference their large holdings, and this thesis approaches crowdsourced georeferencing from the perspective of participatory heritage, taking much inspiration from the idea of the archival commons. To test these ideas, a new extension was created for GeoNode—an open source geospatial content management system—that …

Gis Automated Delineation And Analysis Of Cancer Service Areas In The United States, Changzhen Wang

LSU Doctoral Dissertations

Delineating a meaningful and reliable geographic unit pertaining to cancer care is essential in examining geographic variations in cancer care for better analysis, management, and planning. Public health researchers have devoted great efforts to defining various service areas, which; however, lack scientific rigor or are unrepresentative of the highly specialized cancer care markets, and their methods have become obsolete in the era of big data and high geo-computation. This study develops the “Spatially Constrained Leiden (ScLeiden)” method, a network community detection algorithm in Geographic Information Systems (GIS), and applies it to delineate a series of coherent cancer service …

Baseline Differences In Driving Frequency As A Predictor Of Cognitive Decline, Luke R. Miller

LSU Master's Theses

Driving is a complex task heavily dependent on cognitive functions which can decline with age including executive functions and processing speed. Although driving cessation as a predictor of cognitive changes has been studied, driving frequency is understudied in the literature. Thus, the objective of the current study is to evaluate the predictive utility of driving frequency at baseline toward objective cognitive decline beyond other factors associated with cognitive decline (e.g., depression, general functional mobility). The sample included a subset of 1,426 older adults (M age = 77.6, SD = 7.1) from the Rush University Memory and Aging Project. Participants completed …

Winding Down River Road, Gillian Harper

LSU Master's Theses

As a mechanism to explore my temporary home in Louisiana, Winding Down River Road is a collection of artworks that integrates natural materials collected from landscapes in southern Louisiana with steel and petroleum-based products. My interest in researching environmental issues, ecology, and industry has shaped my vehicles for observation and how I generate data. Through a variety of methodologies, I am considering how climate change is forcing many of us to re-contextualize how our home can be affected by the very industries we rely on. Personal engagement with residents living in the dystopian atmosphere of southern Louisiana’s industrial corridor and …

Development And Validation Of A Measure For Social Support: Perceived Social Support Inventory, Lindsay Marie Clark

LSU Doctoral Dissertations

Abstract

The literature consistently acknowledges the protective function of social support against various negative psychological and physiological outcomes (Cohen & Wills, 1985; Dunst et al., 1986; Taylor, 2011; Uchino, 2009). Further, social support can emerge from different members that comprise an individual’s social network, such as friends, family, teachers, colleagues, and members of common interest groups. Given the important role that social support plays in health outcomes, the importance of psychometrically sound measures for assessing the construct is essential for use in research and clinical settings. However, many of the current measures of social support are outdated, are limited in …

Local And State Climate Initiatives In Louisiana Since 2005: Content And Thematic Analyses, Jessie F. Parrott

LSU Master's Theses

Louisiana is uniquely exposed to severe weather because of its geography and climate. Louisiana’s extreme weather is exacerbated by anthropogenic climate change, which will worsen in the future. The risks its population and environment are exposed to has generated several policies and planning documents, nine of which are analyzed in this thesis. Three plans are from the state level, three are from the parish level, and three are from the urban (New Orleans) level. These planning documents pose various adaptation and mitigation actions to ameliorate and address multiple climate issues. These actions utilize specific mitigation strategies. The content and thematic …

Parasocial Relationships With Online Influencers, Sydney Reynolds

LSU Master's Theses

Current research on parasocial relationships has a focus on the media consumer and the media personae in television or film where the media consumer exerts time and emotional energy into the relationship while the character is unaware of their existence. The purpose of this study is to explore the Influencers and further conceptualize the term parasocial relationship to include these online mediated relationships and interactions. This study explores parasocial relationships and what is associated with them in the context of social media with respondents who consistently engage with social media Influencers. Social media Influencers address their audiences personally and share …

Factors Associated With Racial And Ethnic Minority Youths' Mental Health Help-Seeking At School, Sam Allouche

LSU Doctoral Dissertations

Despite the high prevalence and associated consequences of mental health problems in youth, adolescents with these problems are often left untreated. This service gap is even greater in racial and ethnic minority youth who not only engage in treatment less frequently, but also experience far greater discrimination and systemic inequality than non-ethnic or racial minority students; factors further contributing to a need for service. Schools may provide an ideal location to treat mental health problems in youth, in part because schools eliminate structural barriers, but also because school staff have an opportunity to observe students across a range of functioning. …

Individual Differences In The Criminogenic Effects Of Discrimination: An Exploration Of The Role Of Impulse Control And Callous-Unemotional Traits, Toni Walker

LSU Doctoral Dissertations

The association between perceived discrimination and engagement in criminal offending has been well studied, especially in samples of minority (predominantly Black, Hispanic, and Latinx) adolescents. Several theories have been developed (Social Schematic Theory) and adapted (General Strain Theory) in an attempt to explain how harmful, discriminatory experiences may have an effect on an individual’s behavior. There may be variability in how an individual responds to perceived discrimination, however, but the moderating role of personality characteristics has not been explored. Impulse control and callous-unemotional (CU) traits are both established predictors of offending and may also relate to the mechanisms that theories …

Entities: A Field Of Imaginary Games, Thrasyvoulos Ioannis Kalaitzidis

LSU Master's Theses

With this body of work, I am looking for visual symbols that help communicate unuttered meanings through storytelling and stimulate an affectual response to the viewer. This exploration is presented in two different forms: a surreal sculptural installation and a board game. The installation consists of large-scale sculptures made from light and soft materials (polyurethane foam, plastic waste, paper) that are available to move inside the gallery, while the board game is presented as a set of 3D prints with instructions on how the participants can play it. The materials used in the installation suggest a way to transform waste …

The Effects Of Paired Kinesthetic Movements And Embedded Pictures On Literacy Skills With Preschoolers, Erica Lozy

LSU Doctoral Dissertations

Reading difficulties during childhood often continue during adulthood and result in adverse effects (e.g., unemployment, poverty). A common method to teach early literacy skills is via multisensory instructional programs, which use combinations of mnemonic devices, such as visual, auditory, tactile, and kinesthetic movements. The current literature on the effects of pairing visual mnemonics and kinesthetic movements with literacy skills, either in isolation or in combination, is sparse. The purpose of Study 1 and Study 2 was to compare the efficacy, generalization, and maintenance of and preference for letter sound interventions with and without mnemonic devices. Study 1 evaluated a traditional …

Mental Health Matters: Mental Health Service Utilization Among African American Emerging Adults, Tamecia Curry

LSU Doctoral Dissertations

Evidence indicates that people of color underutilize mental health services, but little is known empirically about the help-seeking behaviors of African American emerging adults. The present mixed method study utilizes a concurrent design with nested samples for the qualitative and quantitative components to examine willingness to seek help and help-seeking intentions among college students. Data was collected from four location sites including Louisiana State University (n=38), Texas State University (n=15), The University of Southern Mississippi (n=65) and Southern University and A&M College (n=3). Minority and non-minority participants completed the Willingness-To-Seek-Help Questionnaire and …

A Relational Study Of Self-Taught And Formally Trained Musicians: Trends Within Memory And Socioeconomic Factors, Matthew N. Jimenez, Emily M. Elliott

LSU Master's Theses

It has been well documented that musicians perform better in memory tasks than non-musicians. The current study utilized self-taught musicians, formally trained musicians, and non-musicians, and focused on short-term memory (STM), musicianship, and SES factors to explore this finding. Do the memory benefits of musical training extend to self-taught musicians? First, we addressed musicianship amongst all groups using the Goldsmith’s Musical Sophistication Index (GMSI), which contained subjective and objective measures. The subjective measure was a survey regarding the role of music in daily life. In the objective measures, participants completed tests of beat and melody perception. To measure STM, participants …

Organizational Commitment Profiles And Employee Well-Being: A Latent Profile Analysis, Hannah E. Perkins

LSU Master's Theses

The present study examined the influence that employees’ organizational commitment profile has on both work and non-work outcomes. While the nomological network of the three-component model of organizational commitment has been studied widely, the application of the latent profile analysis (LPA) has changed the way researchers explore organizational commitment. Specifically, while variable centered approaches (e.g., correlations, multiple regression) measure each type of commitment independently and ultimately assume the linear relationships detected are applicable to every employee, a person-centered approach (e.g., latent profile analysis) groups individuals according to patterns of the reported target variables, allowing researchers to explore the combined or …

Preventing Brand Activism From Backfiring: How The Use Of An Ingroup Model Can Limit The Negative Effects Of One-Time Csr History, Cole C. Dunnam

LSU Master's Theses

Brands are beginning to engage in corporate social advocacy (CSA) with social movements to form deeper connections with their audience, but not all are successful. This thesis asks why a brand’s target audience considers some CSA campaigns as more authentic than others. In Study I, I use Twitter data to conduct an exploratory analysis that applies existing research to two extreme CSA cases: Nike’s Emmy-winning “Dream Crazy” campaign starring Colin Kaepernick and Pepsi’s unsuccessful “Live for Now– Moments” campaign starring Kendall Jenner. Pepsi failed despite its history of corporate social responsibility (CSR) initiatives. I suggest that group identity theory impacts …

Public Safety Response For Persons With Serious Mental Illness: A Systematic Review Of Literature, Ashley Bailey

LSU Master's Theses

There are 13.1 million adults living with serious mental illness (SMI) in the United States. It is estimated that 356,000 people with SMI are incarcerated in the United States. Many advocates believe that police reform/alternatives to traditional policing could assist in lowering incarceration rates among persons with SMI, and improve outcomes for both the officer and the person with SMI during police contact.

Does Chronic Risperidone Administration Affect Food Reinforcement In Adulthood In Mice?, Francis Torres, Paul Soto

LSU Master's Theses

Second-generation antipsychotics (SGAs) increase weight gain and food consumption in humans and non-human animals. It has been speculated that SGAs increase the reinforcing effects of food, which increases food consumption and drives weight gain. The current study evaluated the effects of risperidone on sucrose reinforcement in male and female C57BL/6J mice using economic demand assessments. Demand for sucrose was measured by varying the fixed ratio (FR) value required to produce sucrose delivery across experimental sessions using five FR values: 1, 5, 15, 30, and 45. The effects of acute risperidone administration on demand for sucrose were first assessed by orally …

Musculoskeletal Markers: A Comparison Of The Influence Of Three Biological Factors On Robusticity, Megan Greene

LSU Master's Theses

Research suggests that musculoskeletal markers (MSMs) can provide information about the lives of deceased individuals. The majority of studies focus on single factors that influence the morphology of MSMs in pre-modern societies (i.e., medieval, hunter-gatherers, preindustrial, etc.). This study analyzes MSMs of modern skeletons of 72 females and 83 males from the United States whose ages at death range from 30 to 89 to understand the relationship between various biological factors and MSM morphology. Eight MSMs (attachments of pectoralis major, deltoid, brachialis, supinator, iliopsoas, gluteus maximus, quadriceps, and soleus) were analyzed and categorized as phases zero, one, two, or three …

Cross-Issue Agenda Setting From Racism To Immigration: Spreading Activation Or Group Threat?, Martina Santia

LSU Doctoral Dissertations

Little research to date offers evidence for the “cross-issue agenda setting effect,” that is transfer of salience from media coverage of racism to perceived importance of immigration. Laboratory experiments afford the opportunity to facilitate causal inference in determining whether this cross-issue effect is due to a cognitive mechanism of spreading activation (as conventionally assumed in agenda setting research) or to a cumulative, affective process driven by perceived threat to a certain identity group. Observational data, on the other hand, allow to externally validate the experimental results beyond the constrained settings typical of laboratory experimentation.

This dissertation combines the strengths of …

Assessing The Effect Time And Burial Environment Have On The Use Of The Lamendin Dental Age Estimation Method In Two Archaeological Samples From Jordan, Sabrina L. Williamson

LSU Master's Theses

The Lamendin method is a dental age estimation method that can be used by biological anthropologists when the skeletal anatomy is not available. The Lamendin method utilizes an index derived from measurements of the tooth root height (RH), periodontal line height (PLH), and root transparency height (RTH) to estimate the age of an individual. Although this method is often used in forensic contexts, its presence in the bioarcheological literature is almost non-existent. Research that mentions the Lamendin method conflict about whether the method can be used in specimens with longer postmortem intervals (PMIs) and in various depositional environments. This study …

The Use Of Non-Immersive Virtual Reality As A Functional Rehabilitation Tool For Older Adults With Cognitive Decline, Ross M. Divers

LSU Master's Theses

There is currently no cure for age-related cognitive decline or dementia and current pharmacologic interventions have had limited success at improving daily functioning. Consequently, older adults who experience cognitive decline require assistance with daily activities, which can be quite expensive and lead to caregiver burden. Repeated performance of everyday tasks has been shown to improve performance but requires supervision and direction by another person. The present study evaluated a low-cost computer training program that will use non-immersive virtual reality to enable participants with dementia or cognitive decline to independently practice meaningful everyday activities (e.g., meal preparation). Participants (N= 8) with …

Analysis Of Spindle Whorls And Fishing Weights From The Ancient Maya Trading Port Of Moho Cay, Belize, Kaitlin Samples

LSU Master's Theses

Abstract

Trading, fishing, and spinning thread were important parts of the ancient Maya world. Iconography and archaeological excavations have shown the importance of the three activities. The ancient Maya had an extensive trade network along the Belize River. The site of Moho Cay was an important trading area within this network. Excavations at Moho Cay show the importance of trade, fishing, and spinning at Moho Cay. The excavations done in 1979, led by Dr. McKillop and the team of Trent University, yielded a large sample of spindle whorls and fishing weights. Analysis of these spindle whorls and fishing weights is …

The Influence Of Clutter On Target Prevalence And Decision Making During Visual Search, Brandon Eich

LSU Master's Theses

Participants are sensitive to target prevalence effects in visual search. Low prevalence of targets leads to increased miss rates and shorter response times, and high prevalence of targets leads to increased false alarm rates and longer response times. These effects have been explained using the Multiple-Decision Model (MDM), in which two decisions impact performance during serial visual search. The first decision is whether an inspected item is a target. The second decision is whether the search should be ended with a target-absent response. Target prevalence influences these decisions, evidenced by changes in miss rate, false alarm rate, and response time. …
