Intrathecal (G4c2)149 Delivery In C9orf72-Deficient Mice Yields Mild Motor Dysfunction And Als/Ftd Pathological Hallmarks, Katelyn Russell, Amelia Shahrabi, Suleyman Akerman, Matthew D. Byrne, Jeffrey Rothstein, Davide Trotti, Brigid Jensen, Aaron Haeusler
Farber Institute for Neuroscience Faculty Papers
A repeat expansion in C9ORF72 is the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), yet existing mouse models incompletely engage spinal regions implicated in disease. Here, an adeno-associated virus encoding (G4C2)149 repeats was delivered via neonatal intrathecal injection, achieving widespread CNS expression with robust spinal cord targeting. This approach was applied to mice with graded loss of endogenous C9orf72 to interrogate both gain- and loss-of-function mechanisms. Longitudinal motor, behavioral, and pathological analyses revealed that repeat expression primarily drives mild, progressive muscle weakness, whereas coordination deficits were largely genotype dependent. Subtle gait abnormalities and hyperactivity …
Gold Medal Girl: Media Representations Of Aly Raisman During The Larry Nassar Scandal Through Lenses Of Whiteness, Vulnerability, And "Good" Patriarchy, Anna Mischelle Dean
Gold Medal Girl: Media Representations Of Aly Raisman During The Larry Nassar Scandal Through Lenses Of Whiteness, Vulnerability, And "Good" Patriarchy, Anna Mischelle Dean
Electronic Theses and Dissertations Archive
This thesis analyzed two media texts about former Olympic gymnast Aly Raisman and how these texts constructed her identity during and after the Larry Nassar scandal. I analyzed these texts through the lenses of whiteness, vulnerability, and carceral feminism. Looking at how the media acts as a disciplinary apparatus in this case, I argue that women athletes’ bodies are portrayed as having a vulnerability to abuse that only the "good" patriarchy can address. I seek to show that the media use depictions of women’s vulnerability and need for patriarchal help to remind women athletes that, in cases of abuse, who …

Beyond Predation: Invasive Green Crab (Carcinus Maenas) Alters Juvenile Pacific Oyster (Magallana Gigas) Function And Survival Across Environmental Gradients, Isabel Helena Mize
Dissertations and Theses
The establishment of the invasive green crab, Carcinus maenas, creates ecological and economic impacts in estuaries, particularly through predation on bivalves and alteration of species interactions. This thesis evaluates the direct predation, non-consumptive predator presence, and spatial management implications of C. maenas impacts on filtration rate of juvenile Pacific oysters, Magallana gigas, across laboratory, field, and GIS-based vulnerability mapping approaches. In laboratory conditions, clearance rates of M. gigas were measured over 72 hours across two temperatures (14°C and 18°C) and predator treatments including C. maenas, Pacific rock crab (Romaleon antennarium), both predators together, and a …
“He’S Got The Whole World In His Hands”: Seed Sovereignty And Agricultural Decision Making In Southeastern Kenya, Caroline Stahley
“He’S Got The Whole World In His Hands”: Seed Sovereignty And Agricultural Decision Making In Southeastern Kenya, Caroline Stahley
USF Tampa Graduate Theses and Dissertations
Increasing corporate control of the global seed supply and restrictions to local exchange threaten the autonomy of smallholder farmers and Indigenous communities. This project contributes to agricultural sovereignty movements by examining the decisions farmers make to address climate uncertainty, market volatility, and development agendas. Specifically, how is seed saving practiced and understood in relation to sovereignty? It reimagines what global food systems might look like if investment were directed to producers rather than intermediaries, arguing that cultivators lack support, not knowledge or capacity. Across these domains, seeds act as a motif to describe the concerns, innovations, and visions of farmers.
House Sparrows Reveal Hidden Reservoirs Of Antimicrobial Resistance, Nathan Dowling
House Sparrows Reveal Hidden Reservoirs Of Antimicrobial Resistance, Nathan Dowling
USF Tampa Graduate Theses and Dissertations
Antimicrobial resistance (AMR) is a growing global health threat, yet surveillance for antimicrobial resistance genes (ARGs) remains concentrated in clinical and livestock systems, leaving environmental and wildlife reservoirs comparatively understudied. The objective of this study was to evaluate whether one synanthropic bird species integrates landscape-level antimicrobial resistance pressures across socioeconomic gradients and to identify the predictors most strongly associated with cross-national variation in ARG prevalence. We examined ARG occurrence in the globally distributed house sparrow (Passer domesticus), sampling 205 individuals across eight countries spanning large gradients in economic development, antimicrobial use, and governance structure. Using targeted molecular screening of gastrointestinal …
Using The Good Behavior Game To Decrease Challenging Behavior In Children With Autism Spectrum Disorder, Andrea M. Babb
Using The Good Behavior Game To Decrease Challenging Behavior In Children With Autism Spectrum Disorder, Andrea M. Babb
USF Tampa Graduate Theses and Dissertations
Challenging behavior in school settings can negatively impact academic engagement, social relationships, and access to instruction. Previous research has shown that the Good Behavior Game (GBG) can improve academic performance and decrease challenging behavior. Generally, to play the GBG, the teacher establishes a set of rules (e.g., “remain seated during the lecture”) that the students should follow and divides the class into two teams. When a student on either team breaks a rule, the teacher gives that team a tally or hatch mark. The team with the fewest tallies at the end of the game wins a prize. The current …

Evaluating The Effects Of Response Cards On Active Student Responding And On-Task Behavior With Elementary Students Diagnosed With Autism And Other Disabilties, Joshua N. Alvarado
USF Tampa Graduate Theses and Dissertations
One of the most prominent difficulties that students diagnosed with autism spectrum disorder (ASD) face in their education is consistently engaging in on-task behavior and active participation during whole-class group instruction. The use of response cards is one method that has been demonstrated to have beneficial effects for increasing on-task behavior and active participation for students with disabilities. However, there is limited research on effects with students diagnosed with ASD, particularly elementary students. The purpose of this study was to evaluate the effects of two response card types to increase active student responding, on-task behavior and correct responding for elementary …
Amending Planting Media With Typha-Derived Biochar For Sustainable Horticulture, Elissa Touma
Amending Planting Media With Typha-Derived Biochar For Sustainable Horticulture, Elissa Touma
USF Tampa Graduate Theses and Dissertations
Constructed wetlands are widely used to improve water quality by removing excess nutrients from wastewater and stormwater. Nutrients are stored within wetland vegetation, particularly in fast-growing plants such as Typha. Harvesting vegetation provides an opportunity to permanently remove these nutrients while generating biomass suitable for beneficial reuse. Converting harvested biomass into value-added products such as compost and biochar can support nutrient recovery and sustainable biomass management. In addition, increasing concerns regarding the environmental impacts of peat extraction have created interest in renewable alternatives for horticultural growing media. Therefore, the objective of this study was to evaluate the potential of harvested …

The Hunt For Eden: Humanity’S Journey Home Through The Epics Of Milton And Homer, Hannah Pryor
The Hunt For Eden: Humanity’S Journey Home Through The Epics Of Milton And Homer, Hannah Pryor
Masters Theses
This thesis argues that the recurrent theme of loss and home in the Western Literature tradition reflects humanity’s innate and theological memory of losing Eden. An examination of Homer’s The Odyssey and John Milton’s Paradise Lost in comparison with the Biblical text serve both as literary companions and ethical dichotomies. Some of the greatest pieces of Western Literature highlight the greatest tragedy and triumph the world has ever and will ever know – the loss of Paradise and the hunt for Eden. Nothing is perhaps more heartbreaking and inspiring than reading and living the story of humanity’s journey home.
Creation As Calling: The Intersection Of Faith And Craft, Alexandra J. Slyman
Creation As Calling: The Intersection Of Faith And Craft, Alexandra J. Slyman
Masters Theses
This thesis, titled "Creation as Calling: The Intersection of Faith and Craft," explores the relationship between creative writing—specifically within the epic fantasy genre—and Christian belief. The work is divided into three distinct sections: an Artist Statement, a Craft Element Paper, and a Creative Manuscript. The Artist Statement establishes a creative philosophy grounded in the biblical doctrine of imago Dei, or being made in the image of God. It argues that the human impulse to create is a divine mandate to reflect God’s glory and a means of bearing witness to the "great story of salvation". The author contends that fiction …
Fear Appeal Advertising As A Tool For Preventative Medicine And Chronic Disease Mitigation, Samuel J. Moore
Fear Appeal Advertising As A Tool For Preventative Medicine And Chronic Disease Mitigation, Samuel J. Moore
Undergraduate Honors Theses
Chronic disease refers broadly to a group of diseases that develop and progress as individuals age, that last 1 or more years, and that require ongoing medical attention or limit activities of daily living, or both (“About chronic diseases,” 2026). Chronic disease is most often associated with years of compounding effects of poor nutrition and physical inactivity. Since negative emotion-based advertising, also known as “fear campaigns,” have been shown to be effective forms of communication for other health related topics (Huang et al, 2017), we sought to test a fear campaign’s potential to discourage unhealthy physical activity practices in young …

Processing Mechanism And Efficacy Maintenance Strategy Of Ginseng Active Ingredients Based On Spectroscopy Technology, Yang Hantong, Kong Linghui, Jiang Mengmeng, Wang Yingxiu, Li Xiangguo
Food and Machinery
Ginseng, as a medicinal and edible plant, has ginsenosides as its core active components, which are widely applied due to their physiological functions such as antioxidant and anti-inflammatory activities; however, their structures and activities are easily affected by food processing. During processing steps such as cleaning, steaming/boiling, and fermentation, temperature, pH, and microbial enzyme systems alter the types, contents, and stability of active components through reactions such as hydrolysis and oxidation. The intrinsic linkage mechanism of "component transformation-activity-bioavailability" constitutes a core focus and challenge in current research. This study, based on spectroscopic techniques including high-performance liquid chromatography (HPLC), nuclear magnetic …

Effect Of Garlic Paste Addition On Volatile Flavor Substances In Crayfish Tails, Tu Jianqiu, Fu Wenjun, Yang Xiaocong, Jing Lixiang, Zhu Jing, Li Jianfang
Food and Machinery
[Objective] To investigate the effect of garlic paste addition on volatile flavor substances and color attributes of crayfish tails, and provide a theoretical basis for flavor standardization in industrial production.[Methods] This paper adopts gas chromatography-ion mobility spectrometry (GC-IMS ) combined with colorimetric analysis to study the characteristics of volatile components and color parameters (L*,a*,b* values ) of crayfish tails under garlic paste additions of 0%,4.4%,8.8%,13.2%,17.6%,and 22.0%. Principal component analysis (PCA ) is applied to analyze flavor differences.[Results] Colorimetric analysis reveals that garlic paste addition significantly decreases L* from 45.69 to 34.50 and b* from 39.24 to 29.94 (P<0.05), while a* values show a significant difference under the garlic paste addition of more than 13.2% (P<0.05). A total of 53 volatile substances are identified by GC-IMS, and their total content increases gradually with the rising garlic paste addition (highest value in the 22% group at 18 749 and lowest value in the control group at 10 758). Camphene, 2-ethylbutanoic acid, 2-methylbutyl acetate, allyl isothiocyanate, and heptanal are identified as intrinsic flavor markers of crayfish meat. Key contributors to flavor include camphene, 1-heptanol, 3-pentenenitrile, 2,3-pentanedione, diacetyl, and isopropanol. PCA shows that the 13.2%~17.6% group exhibits significantly different flavor characteristics from other groups (PC1 contribution rate of 76%).[Conclusion] Under the garlic paste addition of 8.8%~13.2%, the optimal balance between flavor and color attributes is achieved, while excessive addition of more than 17.6% results in aldehyde overaccumulation and accelerated browning.

Invasive African Fig Flies (Zaprionus Indianus) Have Reduced Cold Acclimation Ability Compared To Cosmopolitan Drosophilid Species, Mia Hollekim, Lucy Smith, Priscilla A. Erickson
Biology Faculty Publications
Zaprionus indianus, an invasive species of fruit fly originating from Africa, has successfully inhabited eastern North America but is thought to be seasonally limited by cold temperatures. We compared the cold acclimation abilities of Z. indianus to six drosophilid species. Each species’ survival at -5°C was tested following acclimation periods at 10°C, 15°C, and 25°C. We found that Z. indianus had a similar baseline cold tolerance to other cosmopolitan species and acclimated following treatment at 15°C. Overall, cold acclimation in Z. indianus was better than tropical species but weaker than some cosmopolitan species, suggesting cold may restrict Z. indianus …
