Singing Strategies Are Linked To Perch Use On Foraging Territories In Heart-Nosed Bats, Grace C. Smarsh, Ashley M. Long, Michael Smotherman

Faculty Publications

Acoustic communication allows animals to coordinate and optimize resource utilization in space. Cardioderma cor, the heart-nosed bat, is one of the few species of bats known to sing during nighttime foraging. Previous research found that heart-nosed bats react aggressively to song playback, supporting the territorial defense hypothesis of singing in this species. We further investigated the territorial defense hypothesis from an ecological standpoint, which predicts that singing should be associated with exclusive areas containing a resource, by tracking 14 individuals nightly during the dry seasons in Tanzania. We quantified the singing behavior of individuals at all perches used throughout the …

Strict Lyapunov Functions And Feedback Controls For Sir Models With Quarantine And Vaccination, Hiroshi Ito, Michael Malisoff, Frederic Mazenc

Faculty Publications

We provide a new global strict Lyapunov function construction for a susceptible, infected, and recovered (or SIR) disease dynamics that includes quarantine of infected individuals and mass vaccination. We use the Lyapunov function to design feedback controls to asymptotically stabilize a desired endemic equilibrium, and to prove input-to-state stability for the dynamics with a suitable restriction on the disturbances. Our simulations illustrate the potential of our feedback controls to reduce peak levels of infected individuals.

Effects Of Tasting And Ingredient Information Statement On Acceptability, Elicited Emotions, And Willingness To Purchase: A Case Of Pita Chips Containing Edible Cricket Protein, Cristhiam E. Gurdian, Damir D. Torrico, Bin Li, Witoon Prinyawiwatkul

Faculty Publications

Sustainable and nutritious alternatives are needed to feed the ever-increasing world population. The successful incorporation of edible-cricket protein (ECP) into foods needs deeper consumer insights. Treatments (plain, Italian, and Cajun pita chips containing 6.9% w/w ECP) were evaluated by subjects for overall liking (OL), emotions, and purchase intent (PI) in three different moments: (1) before tasting, (2) after tasting/before ECP statement, and (3) after tasting/after ECP statement. Attributes’ liking scores were evaluated only after tasting/before ECP statement. Liking scores (mixed-effects ANOVA), emotions, and PI across moments within treatments/across treatments within moments were evaluated. Emotion-based penalty-lift analyses for OL within moments …

Geographic Analysis Of Alcohol-Related Crashes In Nine High-Need Louisiana Parishes, Aimee H. Moles, Austin L. Matthews, John K. Aggrey, Leanna B. Cupit

Reports

This report examines nine Louisiana communities and their alcohol availability concerns from a public health perspective. The nine communities are part of The Louisiana Partnership for Success II (LPFS ll), a 5-year Substance Abuse and Mental Health Services Administration (SAMHSA) grant. The LPFS ll grant is focused exclusively on addressing underage drinking behaviors, consequences, and risk factors among 9 to 20-year-olds in nine high-need, parish-level communities (HNCs) (Louisiana Department of Health [LDH], 2020a). Communities were selected through a data-driven, participatory process and supported to form a cross-sector coalition to implement interventions within those communities. The process for choosing the high-need …

Faculty Publications

There are discussions and debates surrounding forest certification in developing coun-tries. In this study, we surveyed 50 forest-based companies in Sri Lanka (43 wood-based manufacturers and 7 plantation companies) to ascertain their participation in forest certification, current and future forest certification trends, as well as their satisfaction with the performance of Forest Stewardship Council (FSC) certification in its economic, environmental, and social aspects, using an importance–performance analysis (IPA). Study results indicate that certified companies typically focus on exports and supplying raw materials for value-added exporters. The customer demand/signaling mechanism appears to be the primary driver of FSC certification in Sri …

Division of Basic Science Faculty Publications

Asthma is a heterogeneous disease, with multiple underlying inflammatory pathways and structural airway abnormalities that impact disease persistence and severity. Recent progress has been made in developing targeted asthma therapeutics, especially for subjects with eosinophilic asthma. However, there is an unmet need for new approaches to treat patients with severe and exacerbation-prone asthma, who contribute disproportionately to disease burden. Extensive deep phenotyping has revealed the heterogeneous nature of severe asthma and identified distinct disease subtypes. A current challenge in the field is to translate new and emerging knowledge about different pathobiologic mechanisms in asthma into patient-specific therapies, with the ultimate …

Interpretation And Inference For Altmetric Indicators Arising From Sparse Data Statistics, Lawrence Smolinsky, Bernhard Klingenberg, Brian D. Marx

Faculty Publications

In 2018 Bornmann and Haunschild (2018a) introduced a new indicator called the Mantel-Haenszel quotient (MHq) to measure alternative metrics (or altmetrics) of scientometric data. In this article we review the Mantel-Haenszel statistics, point out two errors in the literature, and introduce a new indicator. First, we correct the interpretation of MHq and mention that it is still a meaningful indicator. Second, we correct the variance formula for MHq, which leads to narrower confidence intervals. A simulation study shows the superior performance of our variance estimator and confidence intervals. Since MHq does not match its original description in the literature, we …

A Survey Of Blind Modulation Classification Techniques For Ofdm Signals, Anand Kumar, Sudhan Majhi, Guan Gui, Hsiao-Chun Wu, Chau Yuen

Faculty Publications

Blind modulation classification (MC) is an integral part of designing an adaptive or intelligent transceiver for future wireless communications. Blind MC has several applications in the adaptive and automated systems of sixth generation (6G) communications to improve spectral efficiency and power efficiency, and reduce latency. It will become a integral part of intelligent software-defined radios (SDR) for future communication. In this paper, we provide various MC techniques for orthogonal frequency division multiplexing (OFDM) signals in a systematic way. We focus on the most widely used statistical and machine learning (ML) models and emphasize their advantages and limitations. The statistical-based blind …

The Effects Of Team Surface-Level Diversity On Creativity & Innovation, Roman Mitchell

Faculty Publications

During the last 20 years, the global marketplace has become more competitive due to increased globalization, aggressive market competition, and changing customer demands. This has forced organizations to assemble teams with diverse knowledge, skills, and abilities to remain competitive. However, previous meta-analytic investigations examining the relationship between team surface-level diversity (i.e., race or gender identity), creativity, and innovation have indicated a small negative relationship. Despite the said positive effects of team diversity, theory and empirical evidence suggests that increased surface-level team diversity leads to decreased team collaboration, team cohesion, and diminished creativity and innovation (Bell, 2007).

This study explores the …

An Investigation Of How Previous Diagnoses Affect The Developmental Functioning Of Children At Risk For Autism Spectrum Disorder, Michaela Brown

LSU Master's Theses

Research has shown that children with autism spectrum disorder (ASD) often have co-occurring medical and/or psychiatric disorders. This current study aimed to investigate how previous diagnoses, which may become comorbidities of ASD if diagnosed, affect the developmental functioning of children presenting as at risk for ASD compared to those presenting with no risk. Developmental areas such as communication, motor, adaptive, cognitive and social, as well as overall developmental functioning, were considered in the analysis. 11,970 children under the age of three were studied. Results found that the presence of previous diagnoses significantly predicted developmental functioning, particularly in the motor functioning …

Elgin's "Native Tongue": A "Me Too" Universe?, Amir Barati

Tête à Tête: Journal of Francophone Studies

Suzette Haden Elgin’s novel Native Tongue (1984) provides a fascinating critique of the ideologies inscribed into patriarchal language and evokes an extremely valuable linguistic and political awareness. This article will examine the liability of the ways the novel revolts against the patriarchal society via the introduction of a gynocentric linguistic intervention. I claim, Elgin’s novel showcases an invaluable instance of how it is possible for women to revolt against the pillars of patriarchy through manipulations at the gestalt and schematic level of language and most specifically, the bodily metaphoric quality of the English. This proposed transformation of the schematic and …

Witnessing And The Gaze In Barbusse’S Hell, Rebecca Stobaugh

Tête à Tête: Journal of Francophone Studies

Stripped down to its most basic plot summary, the premise of Henri Barbusse’s 1908 novel Hell, or L’enfer, sounds like the plot of a cheap porno: a man discovers a peep hole in his hotel room and proceeds to spy on the private lives of the people next door. Indeed, the novel obsesses over the erotic; yet, this obsession is often just as unsensual as it is pleasurable, as descriptions of sex become increasingly disillusioning, and the characters, unsatisfied. Moreover, the narrator does not spy on others for a strictly sexual thrill, but because he believes seeing people …

Developmental Functioning Of Infants And Toddlers With Neurodevelopmental Disorders, Megan Callahan

LSU Master's Theses

Autism spectrum disorder (ASD), epilepsy, and cerebral palsy (CP) are some of the most common neurodevelopmental disorders among children with prevalence rates of 1.85% (Maenner et al., 2020), 1.2% (Zack & Kobau, 2017), and between 0.21 and 0.31% (Christensen et al., 2013), respectively. These neurodevelopmental disorders are highly comorbid with each other and with other disorders, such as intellectual disability (ID). While previous research has investigated developmental functioning in these neurodevelopmental disorders, it has primarily focused on only two at a time and in older children or adults. The current study aimed to investigate developmental functioning in these neurodevelopmental disorders …

The Influence Of Perceived Realistic And Symbolic Threat On College Students’ Attitudes Toward Immigrants And Immigration, Brook Shantel Spurlock

LSU Doctoral Dissertations

Immigration has been one of the most dominant and salient political issues during recent presidential election. Unfortunately, the debates surrounding immigration often castigated Latin Americans as threatening, with the intent to spark fear among voters, while increasing the support for anti-immigration policies, such as the border wall and opposition to passage of a law granting citizenship to Dreamers. The purpose of this dissertation was to determine how realistic and symbolic threats influence college students’ attitudes on immigrants and immigration. Very few studies have been conducted on how realistic and symbolic threats influence immigration attitudes and opinions regarding a wide range …

"News At Its Best:" A Case Study Of Boundary Crossing In Social Media Journalism, Bailey L. Williams

LSU Master's Theses

Digitalization continues to redefine the news ecosystem and boundaries that distinguish traditional news organizations from their nontraditional competitors. However, we still know little about how nontraditional organizations that operate entirely on social media are situated within their news ecosystems. This study examines “Reporter News,” a Facebook page that reports local and breaking news in Shreveport, Louisiana. A traditional journalist used the page to report news independently. In January 2020, he left the page in the care of a team of amateur journalists who contributed content to the page. In the amateurs’ care, the Facebook page has continued to amass a …

A Case Study Of Fourth Grade Students' Literacy Difficulties With Mathematical Word Problems, Rosalind Hudson

LSU Doctoral Dissertations

ABSTRACT

Students have had difficulties with mathematical word problems since they were introduced in their early elementary grades. Elementary teachers have dealt with student difficulties in solving mathematical word problems. In addition, elementary teachers are always implementing and searching for research-based strategies to remediate the deficits in solving mathematical word problems. Year after year across the United States, local education agencies implement math and reading curriculums to support students learning in mathematical word problem solving with reading comprehension, but students are still not able to describe their difficulties when they are given mathematical word problems to solve with all the …

Developmental Functioning Of Infants And Toddlers With Autism And Down Syndrome, Celeste Tevis

LSU Master's Theses

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication, as well as restricted interests and repetitive behaviors. Approximately 10% of individuals with ASD also have comorbid genetic or chromosomal conditions, like Down Syndrome (DS). While it was once believed that DS and ASD rarely co-occurred, it has been demonstrated that it is not uncommon for children with DS to also meet criteria for ASD. Due to the difficulties in differentiating between impairments associated with intellectual disability (ID) and ASD symptomology, DS often leads to delayed or misdiagnoses of ASD. This can interfere with early intervention …

As undergraduate students cultivate their scientific knowledge and abilities, several high-impact educational practices such as undergraduate research and global experiences have proven exponentially beneficial for their development and success. Current literature on underrepresented racial and ethnic minorities has focused primarily on the impact of undergraduate research on this subpopulation. However, fewer studies have explored the impact of global research experiences and women of color in international research experiences. Grounded in the theoretical frameworks of Social Cognitive Career Theory, Intersectionality, and Community Cultural Wealth, this present study explored the impact of international undergraduate research experiences on women of color from groups …

Current Methods And Future Directions In Avian Diet Analysis, Brandon D. Hoenig, Allison M. Snider, Anna M. Forsman, Keith A. Hobson, Steven C. Latta, Eliot T. Miller, Michael J. Polito, Luke L. Powell, Samantha L. Rogers, Thomas W. Sherry, David P.L. Toews, Andreanna J. Welch, Sabrina S. Taylor, Brady A. Porter

Faculty Publications

Identifying the composition of avian diets is a critical step in characterizing the roles of birds within ecosystems. However, because birds are a diverse taxonomic group with equally diverse dietary habits, gaining an accurate and thorough understanding of avian diet can be difficult. In addition to overcoming the inherent difficulties of studying birds, the field is advancing rapidly, and researchers are challenged with a myriad of methods to study avian diet, a task that has only become more difficult with the introduction of laboratory techniques to dietary studies. Because methodology drives inference, it is important that researchers are aware of …

Instructional Design Framework For Construction Materials Training, Hazem Jadallah, Carol J. Friedland, Isabelina Nahmens, Charles Pecquet, Charles Berryman, Yimin Zhu

Faculty Publications

The construction industry is suffering, in part, from a lack of training programs offered to the construction workforce. Unfortunately, most construction training and education research focuses on university student education. Integrating education science theory into construction workforce training has the potential to improve industry training but there is a dearth of studies that present details of this integration process. To address this gap, a training framework was developed to educate material stakeholders on material properties, selection, and installation. This framework is based on andragogical and Universal Design for Learning (UDL) principles. An assessment method evaluates training agendas to improve upon …
