Thinking Inside The Box: The Future Of Young Children's Physical Activity And The Home Environment, Chelsea L. Kracht, Amanda E. Staiano

Population and Public Health Science Faculty Publications

Parrish et al.‘s (2021) investigation of caregiver perceptions of preschoolers' physical activity (PA) within the home environment posits important opportunities for public policy to consider space and available opportunities for PA for preschoolers. This study uncovered qualitative themes on preschoolers' PA in the home, referencing the use of indoor and outdoor spaces, adaptations within the home, interplay between space and caregiving, and variability in child's PA. This work sparks a discussion into the current understanding of the home environment for preschooler PA and future research directions. We propose three main areas to bring forward physical activity and public health research, …

Zoos and natural history museums are both collections-based institutions with important missions in biodiversity research and education. Animals in zoos are a repository and living record of the world's biodiversity, whereas natural history museums are a permanent historical record of snapshots of biodiversity in time. Surprisingly, despite significant overlap in institutional missions, formal partnerships between these institution types are infrequent. Life history information, pedigrees, and medical records maintained at zoos should be seen as complementary to historical records of morphology, genetics, and distribution kept at museums. Through examining both institution types, we synthesize the benefits and challenges of cross-institutional exchanges …

Paraphyletic Relationships Revealed By Mitochondrial Dna In The Peromyscus Mexicanus Species Group (Rodentia: Cricetidae), Giovani Hernández-Canchola, Livia León-Paniagua, Jacob A. Esselstyn

Faculty Publications

Although deer mice (Peromyscus spp.) are among the most studied small mammals, their species diversity and phylogenetic relationships remain unclear. The lack of taxonomic clarity is mainly due to a conservative morphology and because some taxa are rare, have restricted distributions, or are poorly sampled. One taxon, P. mexicanus, includes southern Mexican subspecies that have not had their systematic placement tested with genetic data. We analyzed the phylogenetic relationships and genetic structure of P. mexicanus populations using sequences of the mitochondrial gene cytochrome b. We inferred that P. mexicanus is paraphyletic, with P. m. teapensis, P. m. tehuantepecus, and P. …

Faculty Publications

Defining a reliable geographic unit pertaining to cancer care is essential in its assessment, planning, and management. This study aims to delineate and characterize the cancer service areas (CSA) accounting for the presence of major cancer centers in the United States. We used the Medicare enrollment and claims from January 1, 2014 to September 30, 2015 to build a spatial network from patients with cancer to cancer care facilities that provided inpatient and outpatient care of cancer-directed surgery, chemotherapy, and radiation. After excluding those without clinical care or outside of the United States, we identified 94 NCI-designated and other academic …

Boron Proxies Record Paleosalinity Variation In The North American Midcontinent Sea In Response To Carboniferous Glacio-Eustasy, Wei Wei, Wenchao Yu, Thomas J. Algeo, Achim D. Herrmann, Lian Zhou, Jinhua Liu, Qian Wang, Yuansheng Du

Faculty Publications

Salinity variation in ancient epicontinental seas has long been challenging to reconstruct. We determined salinity variation in the Late Pennsylvanian North American Midcontinent Sea based on normalized boron concentrations (B/Ga) and isotopic compositions (δ11B) of bulk shale. We analyzed the Stark Shale Member of the Missourian Stage Dennis Limestone cyclothem in the Charleston core (CC) from the Illinois Basin (eastward, more proximal) and the Iowa Riverton core (IRC) from the Midcontinent Shelf (westward, more distal). Both cores exhibited the same pattern of secular variation, with lower B/Ga and δ11B values at their base and top, recording less saline conditions during …

Observational Study On The Variability Of Mixed Layer Depth In The Bering Sea And The Chukchi Sea In The Summer Of 2019, Xiaohui Jiao, Jicai Zhang, Qun Li, Chunyan Li

Faculty Publications

Based on the CTD data from 58 stations in the Bering Sea and the Chukchi Sea in the summer of 2019, the values of mixed layer depth (MLD) were obtained by using the density difference threshold method. It was concluded that the MLD can be estimated more accurately by using a criterion of 0.125 kg/m³ in this region. The average MLD in the Bering Sea basin was larger than that in the Bering Sea shelf, and both of them were smaller than that in the Bering Sea slope. The MLD increased northward in both the Chukchi Sea shelf and …

A Comparison Of The Remote Food Photography Method And The Automated Self-Administered 24-H Dietary Assessment Tool For Measuring Full-Day Dietary Intake Among School-Age Children, Traci A. Bekelman, Corby K. Martin, Susan L. Johnson, Deborah H. Glueck, Katherine A. Sauder, Kylie K. Harrall, Rachel I. Steinberg, Daniel S. Hsia, Dana Dabelea

Clinical Research Faculty Publications

The limitations of self-report measures of dietary intake are well-known. Novel, technology-based measures of dietary intake may provide a more accurate, less burdensome alternative to existing tools. The first objective of this study was to compare participant burden for two technology-based measures of dietary intake among school-age children: the Automated-Self-Administered 24-hour Dietary Assessment Tool-2018 (ASA24-2018) and the Remote Food Photography Method (RFPM). The second objective was to compare reported energy intake for each method to the Estimated Energy Requirement for each child, as a benchmark for actual intake. Forty parent-child dyads participated in two, 3-d dietary assessments: a parent proxy-reported …

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 …

Music Making And Learning At A School For The Visually Impaired: A Case Study, Jacob A. Peterson

LSU Master's Theses

The purpose of this case study was to investigate the learning environment and the teaching methodologies of teachers at a state school for the visually impaired. Data collection included interviews and observations with field notes with two teachers at LSVI (one music and one non-music teacher) and an interview with a member of the administration. The semi-structured interviews and observations took place in three phases: 1) preliminary interviews in which the participants answered questions about goals for their classrooms, background information, common strategies/methods/tools that they have at their disposal, 2) observations of a class/classes with each of the teachers, 3) …

Machine Learning-Based Bridge Load Posting Prediction, Sai Naga Sasi Aditya Bandaru

LSU Master's Theses

1600 (12%) of Louisiana's 13,000 bridges that allow the passage of people, goods, and services are load posted, meaning they are deemed incapable of securely carrying all legal loads. A machine learning framework for estimating the number of load-posted bridges within a regional bridge portfolio would be extremely valuable in the future for allocating essential resources during long-term planning. A framework of this type is necessary since a significant proportion of the bridges are load posted. Furthermore, deterioration due to aging and future increases in legal loads can compound this situation. In this setting, there is a lack of data-driven …

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.

Acknowledgement, Education, Memory: Reframing The Cemetery Landscapes Of The Enslaved, Aubrey L. Phillips

LSU Master's Theses

The landscape holds onto the nearly imperceivable cemeteries of the formerly enslaved population that have been erased through time, development, and censure of historical narratives in Louisiana. Immediate action is necessary to retie censured chronicles of enslavement to the landscape, educating the public on deep-rooted systemic racism in the contemporary environment. This thesis aims to provide reparations to the Black and descendant communities of southern Louisiana. This work acknowledges the remaining cemetery fragments, reframing and knitting them together as a network of spaces that uphold a more holistic memory of the past.

Storytelling As Design Methodology: Reclaiming Little Manila's Urban Landscape Identity, Alyssa M. Gill

LSU Master's Theses

My thesis explores how landscape design can improve its methods of reclaiming lost cultural stories in the urban landscape, using the example of the Filipino American neighborhood known as Little Manila in Stockton, California. Through interpreting both stories and narratives that surround the neighborhood, I propose a basis for landscape design inspiration that focuses on oral history and lived experience. Using this understanding I propose to design a landscape within in the Little Manila Historic Site that celebrates the community’s history while providing public space for continued community use.

My work focuses on the area of Downtown Stockton that earned …

Louisiana’s Coastal Protection and Restoration Authority has been using dredged sand from onshore and offshore sites for barrier island restoration and beach nourishment projects. Caminada dredge pit (CDP) located on eastern Ship Shoal in inner Louisiana shelf underwent two increments in 2014 and 2016, with material used to restore Caminada Headland and nearby areas. Multiple pits in East Terrebonne borrow areas (ET) right next to CDP were then used for East Timbalier Island and other barrier islands near Terrebonne Bay. ET1, north of CDP, was dredged in 2020, and ET2, west of CDP, was dredged in 2020 and 2021 used …

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 …

From The Mouths Of Women: The Life Model Of Homelessness, Janeal M. White

LSU Doctoral Dissertations

The purpose of this study was to identify commonalities in life events preceding a first episode of homelessness for women living in shelters in Texas. This built on the work of Nooe & Patterson (2010) who identified fourteen factors that contributed to increased risk of homelessness as visualized in the Ecology of Homelessness. While based on existing literature at the time, Nooe & Patterson may not have heard clearly the voices of women with lived experience. The current study sought to explore how these risk factors manifest in the lived experiences of women residing in Texas homeless shelters.

Celebrating Wetland Foodways: Joining Ecosystems & Cultures On The Louisiana Gulf Coast, Deborah La Rue

LSU Master's Theses

Coastal Louisiana is bountiful in cultural and ecological diversity. Spotted with thriving estuaries, meandering bayous and swamps, and rippling grasses of coastal marshes, these wetland ecosystems sequester carbon, purify floodwaters, and buffer against storm surge. Historically, southern wetland landscapes have offered refuge to people of many folk and ethnic traditions escaping violence and oppression. Until the mid-twentieth century, the people living in present-day Terrebonne and Lafourche parishes enjoyed relative isolation from the rest of America, constructing cultural practices that emphasized attachment to wetland plants, animals, and ecosystem dynamics.

Today, changing environmental conditions and high rates of relative sea level rise …

Outcomes Of Building Parasocial Relationships Betweens Brands And Consumers On Social Media, Emily Ritchart

LSU Master's Theses

Social media has fundamentally changed the way brands can communicate and interact with their consumers. By using a survey that asks participants to answer questions about a brand they follow on social media, this study explores the influence of different social media strategies on parasocial relationships and other positive outcomes for brands. Findings show that popular social media strategies of personalized messages, user-generated content, and use conversational/human tone can be used to predict higher levels of PSRs. Furthermore, these results show that brands who build PSRs with consumers can predict high levels of positive brand outcomes including higher positive trust, …

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 Role Of Child Life Specialists In Transitioning Patients With Sickle Cell Disease From Pediatric Care To Adult Management, Amanda Ochiltree

LSU Master's Theses

The transitional period when adolescents and young adults (AYA) no longer see pediatric specialists or pediatricians and transfer their care to adult health care providers is important for all but can be especially complex for AYAs with sickle cell disease (SCD). Disease-specific education, patient and family resources, and psychosocial care are important during the transitional period from adolescence to adulthood. Certified Child Life Specialists (CCLSs) are trained to provide developmentally appropriate preparation and education, psychosocial support, encouragement of emotional expression, and the opportunity to form trusting relationships with the medical care team (Romito et al., 2021). CCLSs work with the …

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 …

Connections Between Interglacial Variation And Lithological Variability Within Midland Basin Permian Shale Rocks In Martin County, Texas, Helen Rice Hammon

LSU Master's Theses

The Upper Pennsylvanian (323.2–289.9 Ma) and Lower Permian (289.9-251 Ma), (Wolfcamp and Spraberry formations) interval of the Midland Basin, West Texas, contains a mixed succession of shale, carbonate, and siltstone/sandstone lithofacies that accumulated in a deep-water marine environment under variable hydrographic restrictions. The heterogenous stratigraphy found in the Wolfcamp and Spraberry formation was formed in response to variations in sea level and a transition from a glacial to an interglacial climate during the Early Permian. These fluctuations left behind alternating beds of mudstone and carbonate, interwoven with thin sandstone beds. Because the Wolfcamp and Spraberry formations are highly heterolithic, it …

Recently Integrated Alu Elements In Capuchin Monkeys: A Resource For Cebus/Sapajus Genomics, J M. Storer, J A. Walker, C E. Rockwell, G Mores, J M. Storer, J D. Orkin, A D. Melin, K A. Phillips, C Roos, M A. Batzer

Faculty Publications

Capuchins are platyrrhines (monkeys found in the Americas) within the Cebidae family. For most of their taxonomic history, the two main morphological types of capuchins, gracile (untufted) and robust (tufted), were assigned to a single genus, Cebus. Further, all tufted capuchins were assigned to a single species, Cebus apella, despite broad geographic ranges spanning Central and northern South America. In 2012, tufted capuchins were assigned to their genus, Sapajus, with eight currently recognized species and five Cebus species, although these numbers are still under debate. Alu retrotransposons are a class of mobile element insertion (MEI) widely used to study primate …

Exploring Cognitive Associations Of Athletes’ Activism Through Social Issue Primes: A Convergent Analysis, Anthony Ciaramella

LSU Doctoral Dissertations

Contemporary athletes are using their platforms to discuss more social activism issues than ever before. This dissertation examines how attitudes and perceptions of activist athletes may differ based on the social activism issues they advocate for. Further, how different social activism issues may prime individuals to associate different gender and racial stereotypes to the athletes involved. To accomplish this goal, a mixed methods convergent approach was used to explore how certain social activism issues and athletes’ level of activism involvement alter perceptions of the issues and the athletes themselves. This approach combines findings from study 1, in-depth interviews with sports …
