Comparing Thermal Imaging Of New York City From 1988 To 2025, Amelia R. Slaton

Scholars Week

My project compared the urban heat island effect on New York City from 1988 to 2025. After looking at the risks associated with the heat island effect on local life I compared Landsat 5 imaging from 1988 and 1989 to Landsat 9 imaging from 2025 to find any differences between the thermal output of New York City. I then used images from both inner and long island area of New York from both time periods. As well as, the reason for New York's large thermal output compared to other surrounding areas and what the city is doing to combat the …


Sensitive Fluorescence Quantitation And Efficient Free Radical Characterization Of N‑Glycans Via Lc-Flr-Hrms/Ms With A Novel Fluorescent Free Radical Tag, Rayan Murtada, C. J. Szafranski, Maria Tevletidis, Shane Finn, Wilthon Gilles, Tabia Tahsin, Jinshan Gao Apr 2025

Sensitive Fluorescence Quantitation And Efficient Free Radical Characterization Of N‑Glycans Via Lc-Flr-Hrms/Ms With A Novel Fluorescent Free Radical Tag, Rayan Murtada, C. J. Szafranski, Maria Tevletidis, Shane Finn, Wilthon Gilles, Tabia Tahsin, Jinshan Gao

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

Glycans are some of the most difficult biomolecules to analyze owing to their branching tendencies as well as their regiochemical and stereochemical diversity. Yet, the correlation between various pathological states and glycan quantity or structural alterations has demonstrated the importance and urgency for the development of a more robust glycan analytical technique. Furthermore, the manufacturing and regulation of biopharmaceuticals demands a feasible and improved analytical approach toward the characterization and quantitation of glycosylations. Unfortunately, multiple commercially available glycan tags lack, in combination, liquid chromatography detection sensitivity, chemical stability and, most importantly, optimal glycan characterization capabilities. Therefore, a novel fluorescent tag …


Dictating The Divine: Revisiting Authorship, Intention, And Authority From Sacred Texts To Generative Ai, James Hutson, W. Travis Mcmaken Apr 2025

Dictating The Divine: Revisiting Authorship, Intention, And Authority From Sacred Texts To Generative Ai, James Hutson, W. Travis Mcmaken

Faculty Scholarship

This article interrogates the historical practice of mediated authorship in religious texts to draw critical parallels with contemporary debates surrounding generative artificial intelligence (AI), specifically large language models (LLMs). By juxtaposing the mediated authorship of sacred texts, such as the Hebrew Bible and New Testament—where figures like the Apostle Paul dictated theological concepts to scribes who infused these directives with their interpretive insights—with the generative processes of LLMs, this research underscores the shared dynamics of co-constructed authorship across historical and technological contexts. Employing interdisciplinary methodologies from art history, textual studies, and reception theory, as well as theological and biblical studies, …

USF Tampa Graduate Theses and Dissertations

This dissertation explores the algebraic and combinatorial structures arising from the study of knot theory through the lens of quandles, their colorings, and associated quiver and ring constructions. It is organized around three central themes: the analysis of quandle coloring quivers for torus links, the development of polynomial invariants and quiver invariants for stuck knots and links, and the algebraic and graphical study of quandle rings. The first chapter begins with an introduction to relevant concepts throughout the dissertation.

In the second chapter, we classify quandle coloring quivers of torus links using dihedral quandles. We describe these quivers as weighted …


The Fear Of Replacement: How Ai Panic In Journalism Mirrors Existential Crisis In Industry, James Hutson Apr 2025

The Fear Of Replacement: How Ai Panic In Journalism Mirrors Existential Crisis In Industry, James Hutson

Faculty Scholarship

This study systematically examines the portrayal of artificial intelligence (AI) errors, such as hallucinations and deepfakes, in journalistic contexts, evaluating whether these narratives reflect a broader existential anxiety about AI's role in reshaping journalism. Using a systematic literature review combined with a qualitative content analysis of recent AI-focused news reports, this study identifies recurring themes in media coverage to assess the accuracy and context of reported AI errors relative to actual technological limitations and affordances. Findings suggest that while AI errors are comparatively rare, they receive amplified coverage, often fueling public mistrust in AI technologies. Nevertheless, a balanced examination reveals …

Bringing Different Disciplines And Competitions In Your Classroom, Eric Chan-Tin, Mohammed Abuhamad

Computer Science: Faculty Publications and Other Works

It is well-known that cybersecurity does not belong only to computer science/engineering. Other disciplines such as Psychology, Criminal Justice, Sociology, and Political Science can have a great impact in cybersecurity research and education. Students taking only courses are at a disadvantage and should be encouraged to participate in cybersecurity competitions to obtain real-world skills. This lightning talk will look at incorporating two aspects in an interdisciplinary cybersecurity program/curriculum: 1) different disciplines and majors such as Psychology, Criminal Justice, Political Science, Sociology into the cybersecurity program; and 2) including cybersecurity competitions as an integral part of the cybersecurity classroom and curriculum. …

Detection Of Co2 Locally Generated By Formate Dehydrogenase Using Carbonate Ion-Selective Micropipette Electrodes, Seol Baek, Salvador Gutierrez-Portocarrero, Rokas Gerulskis, Shelley D. Minteer, Sean R. German, Henry S. White

Chemistry Faculty Research & Creative Works

Many technologies involve immobilizing catalysts such as enzymes on surfaces, and the catalytic activities or functional efficiencies of these surface-bound catalysts can vary depending on orientations, localized binding sites, active sites, and intrinsic molecular nature. Accurate and rapid quantification of reaction products from surface-immobilized catalysts is crucial for understanding the selectivity, mechanisms, and reaction dynamics of catalytic systems and for revealing heterogeneous catalytic activities and reaction sites for applications such as biosensors and energy conversion/generation systems. Here, we demonstrate the feasibility of localized enzymatic activity measurements using microscale carbon dioxide (CO2)-sensitive ion-selective electrode (ISE) pipettes (0.5-2.5 μm tip …

Prenatal Exposure To Pm2.5 Concentration And Risk Of Preterm Birth In New Mexico; A Seasonal Pattern And Spatio-Temporal Modeling., Onyedikachi J. Okeke

Mathematics & Statistics ETDs

This study investigates the association between prenatal PM2.5 exposure and preterm birth risk in New Mexico (2014–2021). Using descriptive statistics, time series models, and spatial analyses, findings show an average preterm birth rate of 14.87 per 1,000 live births, with moderate correlation (r = 0.727) between PM2.5 levels and very preterm births. While traditional models revealed no significant global effect, spatial methods such as Geographically Weighted Regression (GWR) and Multiscale GWR uncovered strong spatial heterogeneity. PM2.5 effects varied by county (coefficients: -0.00154 to 0.00150), with clustering evident in 2018–2019 (Moran’s I = 0.155–0.174). Results highlight the limitations of global models …


Predicting Capture And Survival Probabilities Of The Arizona Tiger Salamander: A Comparison Of Capture-Recapture Models, Brittney Nelson Apr 2025

Predicting Capture And Survival Probabilities Of The Arizona Tiger Salamander: A Comparison Of Capture-Recapture Models, Brittney Nelson

Scholars Week

Capture-recapture models are essential tools for estimating population dynamics in ecological studies. A fundamental component of these models is the capture history matrix, which records individual detection over time and serves as the basis for estimating survival and capture probabilities. This presentation explores three statistical approaches to these estimations: the Cormack-Jolly-Seber (CJS) model, the Hidden Markov Model (HMM) for CJS, and the Bayesian CJS model. The CJS model provides a likelihood-based framework for estimation, and the HMM CJS incorporates latent states into the model to account for uncertainty in detection. The Bayesian CJS extends this same analysis by integrating prior …


Depth Patterns Of Redear Sunfish Lepomis Microlophus In Kentucky Lake, Justin Graben Apr 2025

Depth Patterns Of Redear Sunfish Lepomis Microlophus In Kentucky Lake, Justin Graben

Scholars Week

Redear Sunfish Lepomis microlophus are a highly sought sportfish known for their size potential, but their ecological behavior in large reservoirs remain poorly understood. In this study, we looked at how Redear Sunfish Lepomis microlophus move vertically in Kentucky Lake. We used acoustic tags with depth sensors to measure the movement of Redear Sunfish both diurnally and seasonally within Kentucky Lake.

During the day, Redear Sunfish occupied significantly deeper waters compared to dawn, dusk, and night (p < 0.0001.). Many fish, including the species in the Lepomis genus, may have a preference for specific light levels for optimal foraging and predation avoidance, even if predation is not the primary concern at larger sizes. This daily pattern was consistent through most seasons, except on average the fish were deeper during the winter season (p < 0.0001).

Understanding the movement patterns of Redear Sunfish is essential for effective species management, especially as their popularity grows and they potentially compete with …


Microcanonical Analysis Of Semiflexible Homopolymers With Variable Bending Potential Width, Michael Gray Apr 2025

Microcanonical Analysis Of Semiflexible Homopolymers With Variable Bending Potential Width, Michael Gray

Scholars Week

I have developed an algorithm for finding phase transition in microcanonical data of simulations of homopolymers. These simulations model the behavior of homopolymers in an array of different conditions. This algorithm is generalized and can be applied to a variety of different systems. It works by taking repeated derivatives of the microcanonical entropy of the system and applying several filters, whose parameters are tuned algorithmically as well. Identification of phase transitions allows for the construction of a phase diagram.

Herbicide Utilization For Regulation Of Botanical Composition Of Grass Swards, A Lackovic Apr 2025

Herbicide Utilization For Regulation Of Botanical Composition Of Grass Swards, A Lackovic

IGC Proceedings (1977-2023)

In Czechoslovak conditions especially in Slovakia the botan­ical composition of grass swards is for different reasons getting worse and this means the decrease of forage value. As all those swards cannot be improved by complete renovation or by direct strip drilling of productive species into the sward, other possibilities are looked for. One for those is the utilization of herbicides combined with adequate fertilization. Retardation or control of unfavourable species destroy the existing competition which causes the different species succession in the sward. Our aim was to make a positive succession of species in the sward by herbicides utilization and …


Allelopathic Influence Of Certain Pasture Weeds, A E. Smith Apr 2025

Allelopathic Influence Of Certain Pasture Weeds, A E. Smith

IGC Proceedings (1977-2023)

Allelopathy, the direct or indirect effect of one plant on another through the production of chemical compounds that escape into the environment (Rice, 1974) occurs widely in natu­ral plant communities (Gressel and Holm, 1964), and is pos­tulated to be one mechanism by which weeds interfere with crop growth (Gressel and Holm, 1964; Bell and Koeppe, 1962; Muller, 1966). Probably the most significant consequence of allelopathy is the alteration of population densities that affect vegetation patterns in plant communities. The actual and potential roles of allelopathy in agriculture have been exten­sively reviewed (Putman and Duke, 1978; Rice, 1974; Rice, 1979). Generally, …


Economics Of Controlling Weeds Of Permanent Pasture, I Popay, N Barlow Apr 2025

Economics Of Controlling Weeds Of Permanent Pasture, I Popay, N Barlow

IGC Proceedings (1977-2023)

In general, inedible weeds of permanent pasture reduce pas­ture dry matter available to stock in direct proportion to their cover (Doyle et al., 1984). Translating the effects of weeds on pasture to reductions in animal production is difficult because (i) pasture value can range from zero to the cost of purchased feed (ii) weed effects and pasture value can vary seasonally and interact and (iii) reductions in pasture availability at one time affect later growth (Auld et al., 1987). There have been few direct measurements of effects of pasture weeds on animal pro­ductivity, because of the co.sts involved. However, simulation …


Weed Development In Tropical Sown Pastures, G.E D. Tiley Apr 2025

Weed Development In Tropical Sown Pastures, G.E D. Tiley

IGC Proceedings (1977-2023)

The use of artificially sown pastures is relatively recent in the tropics. Grasses and legumes have been evaluated for their value to livestock as well as the more traditional use of resting arable land after cropping. Using the criteria of ease of estab­lishment, production under grazing and botanical stability, a number of species and mixtures were recommended for the humid areas of Uganda (Horrell and Tiley, 1970). Control of weed growth during early establishment and suppression of unsown species subsequently were found to be vital for the success of these tropical ley pastures. The results of monitoring weed development in …


Insect Pests As A Limiting Factor In Green Fodder Production In Lucerne, Their Control And Residual Persistence Of Insecticides, V J. Shivankar Apr 2025

Insect Pests As A Limiting Factor In Green Fodder Production In Lucerne, Their Control And Residual Persistence Of Insecticides, V J. Shivankar

IGC Proceedings (1977-2023)

The green fodder production in lucerne suffers serious loss of about 38 % caused by the insect pests like Empoasca sp., Therioaphis maculata Buck, Aphis craccivora Koch and Hypera variabilis Herbst. under the tropical agroclimatic zone of Bundelkhand-India (Shri Ram and Gupta, 1976). Of these H. variabilis is most serious with regular occurrence and world­wide distribution. No work has been reported on the control aspect of these pests in India, except a few on insecticidal evalu­ation (Shri Ram and Gupta, 1975) and the economic injury level of lucerne weevil (Gupta et al., 1982). Need of the studies on the chemical …


Sitona Hispidulus Larvaw As A Stress On Alfalfa Production, A A. Hower, K T. Leath Apr 2025

Sitona Hispidulus Larvaw As A Stress On Alfalfa Production, A A. Hower, K T. Leath

IGC Proceedings (1977-2023)

Sitona weevils are pests of various legumes throughout the world. In the United States, the clover root curculio, S. hispi­dulus (F.) is the major species associated with lucerne (alfalfa) Medicago sativa L. This insect has until recently remained obscure as a pest of this major forage crop. However, a recent trend in premature decline of alfalfa has prompted further investigation of this insect/legume interaction. Godfrey and Yeargan (1987) and Hill et al. (1969) indicated that S. hispi­dulus reduced alfalfa production. While adults S. hispidulus feeding on the foliage is of little consequence, it is the associ­ation of larvae with …


Resistance To Plant Parasitic Nematodes In Ryegrasses And White Clover, R Cook, K A. Mizen Apr 2025

Resistance To Plant Parasitic Nematodes In Ryegrasses And White Clover, R Cook, K A. Mizen

IGC Proceedings (1977-2023)

Field and glasshouse experiments indicate that several nematodes damage ryegrasses and white clover (Cook and York, 1985). Populations of these nematodes under grassland are often at potentially damaging densities. Several nematode species of long-term grassland have co-evolved host relationsh­ips in which host resistance is likely to have been selected. This is of direct practical relevance to the control of three nematodes, widespread in England and Wales: the root-knot nematode (Meloidogyne naasi) on ryegrasses; and the stem nematode (Ditylenchus dipsaci) and cyst nematode (Heterodera trifolii) on white clover. Our objectives have been, first, to identify resistant …


The Effect Of Redlegged Earthmite (Halotydeus Destructor) On Legume Productivity, D J. Gillspie, D A. Nicholas Apr 2025

The Effect Of Redlegged Earthmite (Halotydeus Destructor) On Legume Productivity, D J. Gillspie, D A. Nicholas

IGC Proceedings (1977-2023)

Redlegged earthmite (Halotydeus destructor) (RLEM) is a

serious pest of legume-based annual pastures in southern Australia. Observations throughout Australia show that every year they cause both mortality and growth retardation in emerging pastures in autumn, and are also responsible for reduced seed set in annual legumes in spring (Allen 1986, Norris, 1948). The most common legumes in areas where RLEM occur, are annual Trifolium species, especially T. subterraneum (subclover). However, the recent development of M edicago polymorpha and M. murex for use on acid soils together with the wider use of Ornithopus compressus, has resulted in alternative hosts for these …

Resistance In Cynodon Dactlyon To Spodoptera Frugiperda: Influence Of Strain And Dietary Conditioning, S S. Quisenberry

IGC Proceedings (1977-2023)

The most important warm-season perennial grass in the southern United States is bermudagrass (Cynodon dactylon [L.]). Fall armyworms (Spodopterafrugiperda [J.E. Smith]) are the most damaging insect pests of bermudagrass. Conse­quently, researchers have evaluated improved bermudagrass varieties for resistance to fall armyworm (Leuck et al., 1968; Lynch et al., 1983; Quisenberry and Wilson, 1985; Jamjanya and Quisenberry, 1988). Comparison of results from these studies have been contraditory, whereas Leuck et al., (1968) and Lynch et al., (1983) reported Tifton 292 to be extremely resistant (100 % larval mortality) to fall armyworm, Jamjanya and Quisenberry (1988) found it to have …

A Methodology For Evaluation Of Host Plant Resistance In Brachiaria To Spittlebug Species (Homoptera: Cercipidae), L Lapointe, G Arango, G Sotelo

IGC Proceedings (1977-2023)

Previously underutilized lowlands in tropical America are increasingly being used to produce meat and milk largely due to Brachiaria Griseb., an introducea genus of East African grass. Brachiaria is well adapted to infertile, acidic soils with high aluminium saturation. It is estimated than 16 million hectares have been planted to B. decumbens Stapf and B. humidicola (Rendle) Schweick in Latin America (Toledo and Nores, 1986). The various genera and species of spittlebugs native to the neotropics are the principal biotic factor limiting utilization of Brachiaria as forage in Latin America. Spittlebugs are capable of causing severe damage to susceptible …


Some Effects Of Diseases And Pests On Seed Production In White Clover, And Their Control, M J. Foulkes, B C. Clifford Apr 2025

Some Effects Of Diseases And Pests On Seed Production In White Clover, And Their Control, M J. Foulkes, B C. Clifford

IGC Proceedings (1977-2023)

The UK market for seed of white clover (Trifolium repens L.) cultivars is in the order of 1,000 t within an EEC total of some 3,500 t. Although high yields of around 500 kg ha-1 can be achieved, yields are extremely variable (Hides, Lewis and Mar­shall, 1984) and this may be due in part to pathogenic attack. The results reported here are of a field experiment where dis­eases and pests were controlled by pesticide applications in plots grown under two simulated seed production man­agements.
