The Aging Workforce: How It Relates To Incident Rates Within A Distribution Warehouse And A Chemical Manufacturing Building, Elisabeth V. Jones

USF Tampa Graduate Theses and Dissertations

Over the past 20 years or so, the average age of the global population has slowly increased. This is due to low birth rates as well as increased life expectancy. With this global population aging, there has also been a shift in the global labor market causing a trend termed the “aging workforce.” However, with the aging workforce comes a new set of issues for the health and safety professional because they create new hazards. This is due mostly because of the body undergoing physical, psychological, and cognitive decline as someone ages which causes decreased capabilities. Thus, the purpose of …

Tyramine And Its Amtyr1 Receptor Modulate Attention In Honey Bees (Apis Mellifera), Joseph S. Latshaw, Reece E. Mazade, Mary Petersen, Julie A. Mustard, Irina Sinakevitch, Lothar Wissler, Xiaojiao Guo, Chelsea Cook, Hong Lei, Brian Smith

School of Integrative Biological & Chemical Sciences Faculty Publications

Animals must learn to ignore stimuli that are irrelevant to survival and attend to ones that enhance survival. When a stimulus regularly fails to be associated with an important consequence, subsequent excitatory learning about that stimulus can be delayed, which is a form of nonassociative conditioning called ‘latent inhibition’. Honey bees show latent inhibition toward an odor they have experienced without association with food reinforcement. Moreover, individual honey bees from the same colony differ in the degree to which they show latent inhibition, and these individual differences have a genetic basis. To investigate the mechanisms that underly individual differences in …

3d Musculoskeletal Analysis Of The Rhea Americana Forelimb And Implications For The Evolution Of Avian Flight, Sarah Elizabeth Guzinski

USF Tampa Graduate Theses and Dissertations

To understand the evolutionary gain, and loss, of avian powered flight, attention must be paid to the wing morphology of species across these transitions. However, paleognaths, while being the most well-known flightless birds, have greatly understudied forelimbs. Additionally, current literature regarding their forelimb anatomy generally lacks a three-dimensional (3D), biomechanical approach. Among the flightless paleognaths, the rhea is notable in having the least reduced forelimb. Though not used for flight, the wings of rheas are used in other behaviors such as courtship and threat display, as well as nest defense. In this study, I investigate the forelimb anatomy of an …

Dual Targeted Extracellular Vesicles Regulate Oncogenic Genes In Advanced Pancreatic Cancer, Chi-Ling Chiang, Yifan Ma, Ya-Chin Hou, Junjie Pan, Sin-Yu Chen, Ming-Hsien Chien, Zhi-Xuan Zhang, Wei-Hsiang Hsu, Xinyu Wang, Jingjing Zhang, Hong Li, Lili Sun, Shannon Fallen, Inyoul Lee, Xing-Yu Chen, Yeh-Shiu Chu, Chi Zhang, Tai-Shan Cheng, Wen Jiang, Betty Y S Kim, Eduardo Reategui, Robert Lee, Yuan Yuan, Hsiao-Chun Liu, Kai Wang, Michael Hsiao, Chi-Ying F Huang, Yan-Shen Shan, Andrew S Lee, L James Lee

Pancreatic ductal adenocarcinoma (PDAC) tumours carry multiple gene mutations and respond poorly to treatments. There is currently an unmet need for drug carriers that can deliver multiple gene cargoes to target high solid tumour burden like PDAC. Here, we report a dual targeted extracellular vesicle (dtEV) carrying high loads of therapeutic RNA that effectively suppresses large PDAC tumours in mice. The EV surface contains a CD64 protein that has a tissue targeting peptide and a humanized monoclonal antibody. Cells sequentially transfected with plasmid DNAs encoding for the RNA and protein of interest by Transwell®-based asymmetric cell electroporation release abundant targeted …

Ecosystem Structure And Function Across Western Dryland Ecosystems: A Cross-Site Comparison Of Semiarid Ecosystem Types In Colorado And Wyoming, Christopher W. Beltz, William K. Lauenroth, Ingrid C. Burke

Western North American Naturalist

Drylands extend over large portions of the globe, including a significant share of the western United States, yet they remain understudied. We examined ecosystem structure and function at 3 semiarid dryland sites in Colorado and Wyoming, each of which was dominated by a different ecosystem type and plant community—shortgrass steppe, mixed-grass prairie, and sagebrush steppe. This initial study was conducted to fill gaps in knowledge about how sagebrush steppe compares to dryland grasslands in the western United States. Soil respiration was higher at the sagebrush steppe than at the 2 grassland sites (P = 0.001). Aboveground biomass, microbial abundance, …

Is A Psychotic Anthropology Possible? Or How To Have Inclusive Anthropologies Of Subjectivity And Personhood, John Marlovits, Matthew J. Wolf-Meyer

Faculty Research, Scholarly, and Creative Activity

Dominant anthropological theories of mind, cognition, and consciousness reify particular ways of being in the world as "normal," which marginalizes the experiences of people who do not meet normative expectations of personhood or exhibit nonnormative subjectivities. By focusing on atypical forms of communication and self-representation in the ethnographic record, which draws from work in the anthropology of disability and psychological anthropology, we argue for the need to attend to interactions and behavior as the necessary basis for anthropological studies of personhood and subjectivity. These foci, which build on a foundation provided by affect theory and disability studies, stand to open …

Molecular Mechanisms Underlying Host Immunity In The Drosophila-Parasitoid System And Its Application In A Course-Based Research Experience, Ashley Waring-Sparks

Theses and Dissertations

A functional immune response is essential for the survival of all living organisms. The fruit fly Drosophila melanogaster is a well-established model for studying host immunity as well as metabolic regulation during an immune response. Fruit fly larvae, in nature, are commonly infected by parasitoid wasps whose survival is dependent on the successful parasitization of their host. The immune response that the fly elicits toward the wasp egg is a primitive yet effective process. I characterized the genes induced by a host during infection, identified metabolites present in a host during infection, investigated the role of Ab in the cellular …

Global Health Interventions: The Military, The Magic Bullet, The Deterministic Model-And Intervention Otherwise, Emily Yates-Doerr, Lauren Carruth, Gideon Lasco, Rosario García-Meza

Development Studies Faculty Publications

"Intervention" is central to global health, but the significance and effects of how intervention is practiced are often taken for granted. This review takes interventions into health and medicine as subjects for ethnographic inquiry. We highlight three lines of anthropological contributions: studies of global health interventions that serve imperial and military objectives, studies of "magic bullet" interventions arising from laboratory science, and studies of interventions based on deterministic modeling techniques. We then outline examples of "intervention otherwise," in which people build relations of solidarity and care through global health programming, design interventions to be interactive and adaptable, and use data …

Causal Models And Causal Modelling In Obesity: Foundations, Methods And Evidence, Roger S Zoh, Xiaoxin Yu, Philip Dawid, George Davey Smith, Stephen J French, David B Allison

Children’s Nutrition Research Center Staff Publications

Discussing causes in science, if we are to do so in a way that is sensible, begins at the root. All too often, we jump to discussing specific postulated causes but do not first consider what we mean by, for example, causes of obesity or how we discern whether something is a cause. In this paper, we address what we mean by a cause, discuss what might and might not constitute a reasonable causal model in the abstract, speculate about what the causal structure of obesity might be like overall and the types of things we should be looking …

Bung Karno’S Political Thought According To Pancasila: A Study Of Bung Karno’S Speech On June 1, 1945, And The President Soekarno/Bung Karno’S Pancasila Course Throughout 1958-1959, Ganjar Razuni

Jurnal Wacana Politik

This paper examines the evolution of Bung Karno’s Pancasila concept, tracing its origins from his pivotal June 1, 1945 speech and the comprehensive elucidation of Pancasila during the 1958 Pancasila Course, a crucial moment in shaping its official formulation. Pancasila has become an enduring cornerstone of Indonesian ideology. This prompts a closer examination of Sukarno’s political ideals. This study scrutinizes Bung Karno’s Pancasila ideology within the context of his political philosophy. Methodologically, this article employs a Qualitative-Descriptive approach, primarily drawing on literature and documentary sources. The concept of deconstruction has also used in this article. The findings underscore how Sukarno’s …

Addressing Equity Asymmetries In General Chemistry Outcomes Through An Asset-Based Supplemental Course., Hannah Sevian, Tyson D King-Meadows, Klaudja Caushi, Tamari Kakhoidze, Jessica M Karch

Faculty, Staff and Students Publications

Undergraduate first-semester general chemistry (GC1) functions as a gatekeeper to STEM degrees, asymmetrically impacting students who are nonwhite, from lower socioeconomic groups, non-native English speakers, two-year college transfers, and first-generation in college. Nationally, just under 30% of students earn grades of D, F, or withdraw (termed DFW) in GC1; however, DFW rates are much higher for subgroups underrepresented in STEM occupations. Socioeconomic inequalities tend to increase over an individual's lifetime due to the magnification of cumulative disadvantage. Because undergraduate degrees correlate with higher employment and STEM occupations correlate with higher earnings, GC1 represents a critical path point where disparities can …

A Psychometric Analysis Of Natural Language Inference Using Transformer Language Models, Antonio Laverghetta Jr.

USF Tampa Graduate Theses and Dissertations

Large language models (LLMs) are poised to transform both academia and industry. But the excitement around these generative AIs has also been met with concern for the true extent of their capabilities. This dissertation helps to address these questions by examining the capabilities of LLMs using the tools of psychometrics. We focus on analyzing the capabilities of LLMs on the task of natural language inference (NLI), a foundational benchmark often used to evaluate new models. We demonstrate that LLMs can reliably predict the psychometric properties of NLI items were those items administered to humans. Through a series of experiments, we …

Research Progress On The Regulation And Mechanism Of Borneol On The Blood-Brain Barrier In Pathological States: A Narrative Review Focused On Ischemic Stroke And Cerebral Glioma, Xinghua Tan, Ke Zhang, Wenyin Shi, Zhihu Tang

Department of Radiation Oncology Faculty Papers

Background and Objective: The blood-brain barrier (BBB) serves as a dynamic, selective shield, safeguarding the central nervous system (CNS) by separating the brain from circulating blood, preserving its microenvironment, and ensuring stability. However, in the presence of brain pathology, drug delivery across the BBB and blood-tumor barrier (BTB) becomes challenging, hindering effective treatments. Borneol exhibits promise in bidirectionally modulating the BBB under pathological conditions, suggesting at potential clinical applications for related diseases. Our primary goal in this review is to investigate borneol’s potential clinical utility in bidirectionally regulating the BBB under pathological conditions.

Spatial Structure Of Germination And Seed-Associated Fungi In Tropical Pioneer Seeds, Daniela Varon Garcia

USF Tampa Graduate Theses and Dissertations

Negative density-dependent regulation is the process by which host-specific natural enemies reduce the survival of seeds and seedlings of conspecifics near adult trees, favoring heterospecific recruitment, and ultimately increasing local diversity. Negative density-dependent regulation by fungal pathogens has been consistently reported to promote plant diversity in the tropics, even though they tend to be multi-host and host-specificity is rarely reported. Nevertheless, evidence suggests that host-generalist fungi can have host-specific effects that produce disproportionate negative effects on some plant species but not others, promoting regional diversity. However, such studies have not tested for both host-specificity and distance-dependent effects in fully replicated …

Identification Of Lipids And Cytokines In Plasma And Follicular Fluid Before And After Follicle-Stimulating Hormone Stimulation As Potential Markers For Follicular Maturation In Cattle, Alexandria P. Snider, Renata S. Gomes, Adam F. Summers, Sarah C. Tenley, Mohamed A. Abedal-Majed, Renee M. Mcfee, Jennifer R. Wood, John S. Davis, Andrea S. Cupp

Department of Animal Science: Faculty Publications

The process of follicle maturation leading to ovulation is a key milestone in female fertility. It is known that circulating lipids and cytokines play a role in the follicle’s ability to go through follicular maturation and the ovulatory processes. However, the specific mechanisms are not well understood. We posit that dysregulation of granulosa cells influences the ovarian environment, which tries to adapt by changing released lipids and cytokines to achieve follicular maturation. Eleven non-lactating adult females underwent estrus synchronization with two injections of PGF2 14 days apart. Daily blood samples were collected for 28 days to monitor steroid hormone production …

The Involvement Of Caspases In The Process Of Nuclear Removal During Lens Fiber Cell Differentiation, Rifah Gheyas, A. Sue Menko

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The terminal differentiation of lens fiber cells involves elimination of their organelles, which must occur while still maintaining their functionality throughout a lifetime. Removal of non-nuclear organelles is accomplished through induction of autophagy following the spatiotemporal suppression of the PI3K/Akt signaling axis. However, blocking this pathway is not alone sufficient to induce removal of fiber cell nuclei. While the final steps in fiber cell nuclear elimination are highlighted by the appearance of TUNEL-positive nuclei, which are associated with activation of the lens-specific DNaseIIβ, there are many steps in the process that precede the appearance of double stranded DNA breaks. We …

Similarity Measure Of Plithogenic Cubic Vague Sets: Examples And Possibilities, S. Anitha, A. Francina Shalini

Neutrosophic Systems with Applications

The crisp, fuzzy, intuitionistic fuzzy, and neutrosophic sets are the extension of the plithogenic set, in which elements are characterized by the number of attributes and each attribute can assume many values. To achieve more accuracy and precise exclusion, a contradiction or dissimilarity degree is specified between each attribute and the values of the dominating attribute. A plithogenic cubic vague set is a combination of a plithogenic cubic set and a vague set. The key tool for resolving problems with pattern recognition and clustering analysis is the similarity measure. In this research, we characterize and investigate the similarities between two …

The Herbicide Glyphosate Inhibits Hippocampal Long-Term Potentiation And Learning Through Activation Of Pro-Inflammatory Signaling, Yukitoshi Izumi, Kazuko A O'Dell, Charles F Zorumski

2020-Current year OA Pubs

Glyphosate, a herbicide marketed as Roundup, is widely used but there are concerns this exposure could impair cognitive function. In the CA1 region of rat hippocampal slices, we investigated whether glyphosate alters synaptic transmission and long-term potentiation (LTP), a cellular model of learning and memory. Our hypothesis is that glyphosate alters neuronal function and impairs LTP induction via activation of pro-inflammatory processes. Roundup depressed excitatory synaptic potentials(EPSPs) in a dose-dependent manner with complete suppression at 2000 mg/L. At concentrations ≤ 20 mg/L Roundup did not affect basal transmission, but 4 mg/L Roundup administered for 30 min inhibited LTP induction. Acute …

Tolkien Dogmatics: Theology Through Mythology With The Maker Of Middle-Earth By Austin M. Freeman, Alex (Oleksiy) Ostaltsev

Mythlore: A Journal of J.R.R. Tolkien, C.S. Lewis, Charles Williams, and Mythopoeic Literature

The powerful and highly informative definitions that Freeman applies to Tolkien’s Middle-earth phenomenon in the title of his book create a productive interpretational framework. Myth and mythology in Inklings’ writing were always understood, in an almost Jungian way, as a cultural paradigm flexible enough to embrace the free creativity of the playful human mind and a philosophical postulate, or credo, of the humanistic religious intuition of Christianity. In Freeman’s interpretation, Tolkien’s literary myth in some ways requires a theological background, which, in its turn, leads to inevitable dogma, a statement that reveals the sensitive mechanics of literary myth as it …

The C. S. Lewis Correspondence Project was organized for the purpose of making available to scholars and readers transcriptions of all extant Lewis letters. Its goal is to produce an electronic database of Lewis letters. The first priority of the Project is making available transcriptions of all Lewis letters which are not found in the three volumes of Collected Letters of C. S. Lewis. This will not occur quickly. The timeline on even this small aspect of the Project is likely years in the future as many logistical and technical issues must be resolved.
