Brief Of 20 Professors Of Law And Public Knowledge As Amici Curiae In Support Of Affirmance, Charles Duan, Rachel Bamberger

Amicus Briefs & Court Filings

In Carroll Shelby Licensing v. Halicki, the U.S. Court of Appeals considers whether a car in a film is a "character" for purposes of copyright law. Character copyright protection has proven to be an especially difficult area of the law, and courts and commentators have struggled with the proper boundaries of such protection and whether characters are independently protectable works at all. This brief presents a novel legal argument for resolving the scope of character copyright, at least in the context of inanimate objects in creative works such as cars. While the case law and commentary has to date focused …

Sexual Dimorphism And Divergent Evolutionary Pathways In Primate Cranial Biomechanics: Insights From A Theoretical Morphology Framework, Z. Jack Tseng, Claire E. Terhune Oct 2024

Sexual Dimorphism And Divergent Evolutionary Pathways In Primate Cranial Biomechanics: Insights From A Theoretical Morphology Framework, Z. Jack Tseng, Claire E. Terhune

Anthropology Faculty Publications and Presentations

he mammalian order Primates is known for widespread sexual dimorphism in size and phenotype. Despite repeated speculation that primate sexual size dimorphism either facilitates or is in part driven by functional differences in how males and females interact with their environments, few studies have directly assessed the influence of sexual dimorphism on performance traits. Here, we use a theoretical morphology framework to show that sexual dimorphism in primate crania is associated with divergent biomechanical performance traits. The degree of dimorphism is a significant covariate in biomechanical trait divergence between sexes. Males exhibit less efficient but stiffer cranial shapes and significant …


The Pilling Process: Significance Quest, Self-Verification, And Fusion In Online Incel Forums, Gregory J. Rousis Oct 2024

The Pilling Process: Significance Quest, Self-Verification, And Fusion In Online Incel Forums, Gregory J. Rousis

USF Tampa Graduate Theses and Dissertations

Incels (short for “involuntary celibates) are an online community of men who blame women for their reputed sexual and romantic failures. The misogyny of their worldview, called the blackpill, has inspired multiple instances of real-world violence against women. Alarmingly, we know little about the temporal processes whereby an incel goes from joining an online community to becoming deeply aligned (i.e., “fused”) with the group. This project sought to address this by scraping incels’ most popular web forum and using text analysis to identify psychological mechanisms that could be responsible for incels’ fusion. The resulting dataset consisted of 1,097,841 unique discussion …

Chronic kidney disease (CKD) is a leading cause of morbidity and mortality globally. Maternal obesity during pregnancy is linked to systemic inflammation and elevated levels of the pro-inflammatory cytokine interleukin-6 (IL-6). In our previous work, we demonstrated that increased maternal IL-6 during gestation impacts intrauterine development in mice. We hypothesized that IL-6-induced inflammation alters gene expression in the developing fetus. To test this, pregnant mice were administered IL-6 or saline during mid-gestation. Newborn mouse kidneys were analyzed using mRNA-seq, miRNA-seq and whole-genome bisulfite-seq (WGBS). A multi-omics approach was employed to quantify mRNA gene expression, miRNA expression and DNA methylation, using …

Alzheimer's disease (AD) and Alzheimer's disease-related dementias (ADRDs) are broad-impact multifactorial neurodegenerative diseases. Their complexity presents unique challenges for developing effective therapies. This review highlights research presented at the 2024 Society for Neuroscience meeting which emphasized the gut microbiome's role in AD pathogenesis by influencing brain function and neurodegeneration through the microbiota-gut-brain axis. This emerging evidence underscores the potential for targeting the gut microbiota to treat AD/ADRD.

Mutations And Antibiotic Resistance In Mycobacterium Tuberculosis, Ryan M. Johnson, Bodhi Brady, Nicklaus Busse, Connor Beckman, Hunter Gloden, Joseph Glasrud, Zachary Smith, Hari P. Nepal, Madhav P. Nepal

Life Science Reports

Mycobacterium tuberculosis (MTB) is a bacterium known to target, infect, and destroy lung cells as well as connective tissues within the body. This bacterium is prevalent worldwide and has infected over a quarter of the current world population, becoming one of the most successful pathogens in history. Due to its extreme transmission rates as an airborne pathogen, MTB strains have been treated with antibiotics such as rifampicin and isoniazid, which inhibit bacterial infection in the human body. These first-round drugs remained as successful mechanisms for slowing and killing the pathogen, notably through rifampicin's inhibition of RNA-polymerase and isoniazid’s ability to …

Crocodylian Diversity During The Early Eocene Climatic Optimum In The Golden Valley Formation Of North Dakota, U.S.A., Adam P. Cossette, David Tarailo Oct 2024

Crocodylian Diversity During The Early Eocene Climatic Optimum In The Golden Valley Formation Of North Dakota, U.S.A., Adam P. Cossette, David Tarailo

Biological Sciences Faculty Publications

Rich bone beds from the lower Eocene strata of the Golden Valley Formation of Stark County, North Dakota reveal a speciose sympatric crocodylian fauna. However, analyses demonstrate limited phylogenetic diversity among these co-occurring taxa, and of the four species known for the locality, three are alligatorids and one is a crocodyloid. Phylogenetic hypotheses recover Chrysochampsa mylnarskii as a late lived member of Brachychampsini—a stem-based clade including Brachychampsa montana and all alligatorids more closely related to it than to Caiman crocodilus or Alligator mississippiensis—and a new genus and species, Ahdeskatanka russlanddeutsche groups with species of Allognathosuchus. The crocodylians, partitioned by body …

Ai And Future-Making: Design, Biases, And Human-Plant Interactions, Maliheh Ghajargar Oct 2024

Ai And Future-Making: Design, Biases, And Human-Plant Interactions, Maliheh Ghajargar

Art Faculty Articles and Research

Design researchers and practitioners are turning to generative AI (genAI) to support activities such as ideation and concept development in pursuit of preferred futures. At the same time, genAI is known to have biases, which prompts questions about how these biases might adversely affect design practices. In the domain of sustainable HCI, with its recent trends in human-nature interactions and more-than-human design, the question can be further refined into whether and how genAI biases might perpetuate anthropocentric biases that these practices are increasingly seeking to confront. In the present research, we conducted three workshops, focusing on genAI for human-plant interactions; …


"The Words We Do Not Yet Have." A Creative Inquiry Into Human-Plant Relationships, Maliheh Ghajargar Oct 2024

"The Words We Do Not Yet Have." A Creative Inquiry Into Human-Plant Relationships, Maliheh Ghajargar

Art Faculty Articles and Research

Climate change, loss of plant biodiversity, and ocean pollution signal the drastic changes in our ecology that call us to attend to the needs of more than human forms of life on Earth. Sustainable design and HCI research are responding to this call by offering methods and approaches to design more sustainable products and systems and recently, more than human design is building momentum. This agenda seeks to reform traditional design processes by decentering the creative agency of the dominant socio-economical group of humans and foregrounding those of diverse Others. In this paper, I focus on plants as a nonhuman …


Aspect-Ratio-Dependent Heat Transport By Baroclinic Acoustic Streaming, Jacques Abdul Massih, Remil Mushthaq, Guillaume Michel, Gregory P. Chini Oct 2024

Aspect-Ratio-Dependent Heat Transport By Baroclinic Acoustic Streaming, Jacques Abdul Massih, Remil Mushthaq, Guillaume Michel, Gregory P. Chini

Faculty Publications

Standing acoustic waves have been known to generate Eulerian time-mean ‘streaming’ flows at least since the seminal investigation of Lord Rayleigh in the 1880s. Nevertheless, a recent body of numerical and experimental evidence has shown that inhomogeneities in the ambient density distribution lead to much faster flows than arise in classical Rayleigh streaming. The emergence of these unusually strong flows creates new opportunities to enhance heat transfer in systems in which convective cooling cannot otherwise be easily achieved. To assess this possibility, a theoretical study of acoustic streaming in an ideal gas confined in a rectangular channel with top and …

The Role Of Lymph-Adipose Crosstalk In Alcohol-Induced Perilymphatic Adipose Tissue Dysfunction, Kourtney D. Weaver, Liz Simon, Patricia E. Molina, Flavia Souza-Smith

School of Graduate Studies Faculty Publications

Chronic alcohol use leads to metabolic dysfunction in adipose tissue. The underlying mechanisms and the contribution of alcohol-induced adipose tissue dysfunction to systemic metabolic dysregulation are not well understood. In our previous studies, we found that chronic alcohol feeding induces mesenteric lymphatic leakage, perilymphatic adipose tissue (PLAT) inflammation, and local insulin resistance in rats. The goal of this study was to further explore the link between alcohol-induced lymphatic leakage and PLAT immunometabolic dysregulation, locally and systemically, using in vivo and ex vivo approaches. Male rats received a Lieber–DeCarli liquid diet, of which 36% of the calories were from alcohol, for …

Severe and chronic infections, including pneumonia, sepsis, and tuberculosis (TB), induce long-lasting epigenetic changes that are associated with an increase in all-cause postinfectious morbidity and mortality. Oncology studies identified metabolic drivers of the epigenetic landscape, with the tricarboxylic acid (TCA) cycle acting as a central hub. It is unknown if the TCA cycle also regulates epigenetics, specifically DNA methylation, after infection-induced immune tolerance. The following studies demonstrate that lipopolysaccharide and Mycobacterium tuberculosis induce changes in DNA methylation that are mediated by the TCA cycle. Infection-induced DNA hypermethylation is mitigated by inhibitors of cellular metabolism (rapamycin, everolimus, metformin) and the TCA …
