Virtual Advertising In The Nba: How Arousal Level And Visual Attention Alter Brand Recall And Recognition, Caleb H. Porter

Theses and Dissertations

During the 2020 season, the NBA implemented, for the first time, the use of virtual advertisements. Virtual advertisements are digitally superimposed ads directly on the court that are visible to anyone viewing the broadcasted version of a game. This study used eye-tracking and galvanic skin response (GSR) in conjunction with the limited capacity model of motivated mediated message processing (LC4MP; Lang, 2006a) to a) determine virtual advertising's effectiveness compared to traditional in-stadium advertising and to b) monitor the effect emotional arousal has on advertising recall and recognition. A sample of 176 fans of the Utah Jazz viewed one of four …

The Incumbent’S Curse, Party Institutionalization, And Competitive Factionalism In The Candidacy For South Halmahera Election In 2020, Eko Bagus Solihin, Krisna Rettob, David Effendi

Jurnal Politik

This article investigates the incumbent’s curse in the candidacy process in Indonesia by using Bahrain Kasuba’s failure in the running for re-election in South Halmahera in 2020 as its case study. This study diverges from the traditional scholarship on the incumbent curse, which focuses on the election stage. Instead, we focus on the candidacy stage. Candidacy processes and elections are two different political events. Both have differences in three things: their victory targets, mechanisms, and political processes. These three differences urge the study of the effect of incumbency on candidacy, an important aspect to analyze. This article uses the party …

Differential Function And Maturation Of Human Stem Cell-Derived Islets After Transplantation, Kristina G Maxwell, Michelle H Kim, Sarah E Gale, Jeffrey R Millman

2020-Current year OA Pubs

Insulin-producing stem cell-derived islets (SC-islets) provide a virtually unlimited cell source for diabetes cell replacement therapy. While SC-islets are less functional when first differentiated in vitro compared to isolated cadaveric islets, transplantation into mice has been shown to increase their maturation. To understand the effects of transplantation on maturation and function of SC-islets, we examined the effects of cell dose, transplantation strategy, and diabetic state in immunocompromised mice. Transplantation of 2 and 5, but not 0.75 million SC-islet cells underneath the kidney capsule successfully reversed diabetes in mice with pre-existing diabetes. SQ and intramuscular injections failed to reverse diabetes at …

Origin And Epigenetic Regulation Of Cutaneous T Cell Lymphoma, Carly M. Harro

USF Tampa Graduate Theses and Dissertations

The pathogenesis of Cutaneous T cell lymphoma (CTCL) remains unclear. Using conditional knockout mice, we found that ablation of the genomic organizer Special AT-rich sequence-binding protein-1 (Satb1) caused malignant transformation of mature, skin-homing, Notch-activated CD4+ and CD8+ T cells into progressively fatal lymphoma. Mechanistically, Satb1 restrained Stat5 phosphorylation and the expression of skin-homing chemokine receptors in mature T cells. H3K27 and H3K9 trimethylation occluded the SATB1 promoter in Sézary cells, while inhibition of SUV39H1/2 methyltransferases (unlike EZH2 inhibition), restored protective SATB1 expression and selectively abrogated the growth of primary Sézary cells more effectively than romidepsin. Additionally, using single-cell RNA/TCR sequencing …

Mathematical Modelling Of Syphilis Transmission Dynamics: Impacts Of Mass Media Report, Risky Sexual Behavior And Treatment, Gasper G. Mwanga

Tanzania Journal of Science

Syphilis is one of the deadly sexually-transmitted diseases. This paper studied the impacts of sexual behavior, mass media report and treatment of infected individuals on the dynamics of syphilis transmission. The analytical and numerical analyses of the model are presented. The disease free equilibrium of the model is both locally and globally asymptotic stable when the associated reproduction number is less than unity.  Analysis of the Reproduction number shows that it is not possible to control syphilis disease transmission if the rate of individuals practicing risky sexual behavior is high. Furthermore, the treatment of late (latent and tertiary) syphilis infection …

Comparing Survival And Cause-Specific Mortality Of Different Translocation Release Methods For Desert Bighorn Sheep, Taylor S. Daily, Carlos E. Gonzalez, Louis A. Harveson, Warren C. Conway, Froylan Hernandez

Western North American Naturalist

Historically, desert bighorn sheep (Ovis canadensis mexicana) were prevalent throughout the Trans-Pecos region of Texas. However, they were extirpated by the 1960s due to unregulated hunting, habitat loss, predation, and disease transmission from livestock. Restoration efforts have been successfully conducted by the Texas Parks and Wildlife Department to increase population numbers of resident (i.e., animals that currently populate a region of interest) desert bighorn sheep at Black Gap Wildlife Management Area (BGWMA) through the use of translocations. Because there is a lack of knowledge on alternative release methods for large mammal translocations, our goals were to monitor cause-specific …

Department of Agronomy and Horticulture: Faculty Publications

Microbial symbionts play a significant role in plant health and stress tolerance. However, few studies exist that address rare species of core-microbiome function during abiotic stress. In the current study, we compared the microbiome composition of succulent dwarf shrub halophyte Zygophyllum qatarensis Hadidi across desert populations. The results showed that rhizospheric and endosphere microbiome greatly varied due to soil texture (sandy and gravel). No specific bacterial amplicon sequence variants were observed in the core-microbiome of bulk soil and rhizosphere, however, bacterial genus Alcaligenes and fungal genus Acidea were abundantly distributed across root and shoot endospheres. We also analyzed major nutrients …

Jurnal Penyakit Dalam Indonesia

Since March 2020, the Coronavirus Disease 2019 (COVID-19) pandemic has engulfed the world, including Indonesia, for nearly two years. SARS-CoV-2 has undergone several mutations during its evolution as a pathogen, resulting in various variants of global concern. Variants of this virus are suspected to impede the outbreak resolution and possibly causing the outbreak to spiral out of control. There is still considerable debate and research underway regarding the new SARS-CoV-2 variants. Rapid transmission mechanisms and widespread vaccination coverage have accelerated the virus’s mutation rate and resulted in numerous new variants. To date, this has resulted in the discovery of a …

Are Long-Period Exoplants Around Cool Stars More Common Than We Thought?, Emily Jane Safron

LSU Doctoral Dissertations

The Kepler mission has been the catalyst for discovery of nearly 5,000 confirmed and candidate exoplanets. The majority of these candidates orbit Sun-like stars, and have orbital periods comparable to or shorter than that of the Earth, due to the selection bias inherent in the transit method and the limitations of automated transit search algorithms. We aim to develop a richer understanding of the population of exoplanets around the lowest-mass stars, the M spectral type. We are particularly interested in exoplanets with long orbital periods, which are difficult or impossible to find using standard transit search algorithms. In our study, …

Billbugs In Turfgrass (Sphenophorus Spp.), Desiree Wickwar, Ricardo Ramirez

All Current Publications

Billbugs are weevils, a type of beetle, in the genus Sphenophorus. At least 10 billbug species are known pests of turfgrass and can be found in both warm and cool season turfgrasses throughout the United States. Though billbug adults do feed on the leaves of turfgrasses, it is the larvae that cause visible damage. Larvae feed within the stems and on roots of grasses, leading to the development of yellow or brown patches, with the potential to escalate into large patches of dead turfgrass. Billbug management in turfgrass presents a number of unique challenges, but early monitoring and informed integration …

A Push For Inclusive Data Collection In Stem Organizations, Nicholas P. Burnett, Alyssa M. Hernandez, Emily E. King, Richelle L. Tanner, Kathryn Wilsterman

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Professional organizations in STEM (science, technology, engineering, and mathematics) can use demographic data to quantify recruitment and retention (R&R) of underrepresented groups within their memberships. However, variation in the types of demographic data collected can influence the targeting and perceived impacts of R&R efforts - e.g., giving false signals of R&R for some groups. We obtained demographic surveys from 73 U.S.-affiliated STEM organizations, collectively representing 712,000 members and conference-attendees. We found large differences in the demographic categories surveyed (e.g., disability status, sexual orientation) and the available response options. These discrepancies indicate a lack of consensus regarding the demographic groups that …

Cell Type-Specific Roles Of Stat3 Signaling In The Pathogenesis And Progression Of K-Ras Mutant Lung Adenocarcinoma, Michael J Clowers, Seyed Javad Moghaddam

Faculty, Staff and Student Publications

Worldwide, lung cancer, particularly K-ras mutant lung adenocarcinoma (KM-LUAD), is the leading cause of cancer mortality because of its high incidence and low cure rate. To treat and prevent KM-LUAD, there is an urgent unmet need for alternative strategies targeting downstream effectors of K-ras and/or its cooperating pathways. Tumor-promoting inflammation, an enabling hallmark of cancer, strongly participates in the development and progression of KM-LUAD. However, our knowledge of the dynamic inflammatory mechanisms, immunomodulatory pathways, and cell-specific molecular signals mediating K-ras-induced lung tumorigenesis is substantially deficient. Nevertheless, within this signaling complexity, an inflammatory pathway is emerging as a druggable target: signal …

Coal Fines Migration: A Holistic Review Of Influencing Factors, Faisal Ur Rahman Awan, Muhammad Arif, Stefan Iglauer, Alireza Keshavarz

Research outputs 2022 to 2026

Coal fines can substantially influence coal seam gas reservoir permeability, thus impeding the flow of gas in coal microstructure. The coal fines generation and migration are influenced by several factors, wherein coal fines are generally hydrophobic and aggregate in natural coal seam gas (CSG) under prevailing conditions of pH, salinity, temperature and pressure. This aggregation behaviour can damage the coal matrix and cleat system permeabilities, leading to a considerable reduction of proppant pack conductivity (i.e. fracture conductivity). Several datasets have been reported within the literature on this subject in the last decade. However, a more up-to-date discussion of this area …
