Worldwide, hypertension is the leading risk factor for cardiovascular disease and death. An estimated 122 million people, per the American Heart Association in 2023, have been diagnosed with this common condition. It is generally agreed that the primary goal in the treatment of hypertension is to reduce overall blood pressure to below 140/90 mmHg, with a more optimal goal of 130/80 mmHg. Common medications for treating hypertension include calcium channel blockers (CCBs), angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, beta-blockers, and diuretics. CCBs are one of the most widely studied agents and are generally recommended as first-line therapy alone and in …
The Effect Of Early Postnatal Auditory Stimulation On Outcomes In Preterm Infants, Juliann M. Di Fiore, Gloria Liu, Kenneth A. Loparo, Cynthia F. Bearer
The Effect Of Early Postnatal Auditory Stimulation On Outcomes In Preterm Infants, Juliann M. Di Fiore, Gloria Liu, Kenneth A. Loparo, Cynthia F. Bearer
Faculty Scholarship
Abstract: Preterm infants are deprived of in utero sensory stimulation during the third trimester, an important period of central nervous system development. As a result, maturational trajectories are often reduced in infants born preterm. One such system affected is the brain including the auditory and respiratory control pathways. During normal pregnancy the intrauterine environment attenuates external auditory stimuli while exposing the fetus to filtered maternal voice, intra-abdominal sounds, and external stimuli. In contrast, during the third trimester of development, preterm infants are exposed to a vastly different soundscape including non-attenuated auditory sounds and a lack of womb related stimuli, both …
Modeling The Development Of Borderline Personality Disorder: A Formal Theory Approach, Alexandria M. Choate
Modeling The Development Of Borderline Personality Disorder: A Formal Theory Approach, Alexandria M. Choate
USF Tampa Graduate Theses and Dissertations
Borderline personality disorder (BPD) is a complex disorder characterized by instabilities in emotion regulation, impulse control, and interpersonal relationships. BPD affects adolescent and adult populations at similar rates, with traits often detectable in late childhood or early adolescence. Despite some progress in the understanding of BPD and its development, contemporary theories have yet to address several important questions in the literature. The present study suggests that many limitations associated with current theoretical models of BPD may be attributable to an overdependence on verbally specified, or weak theories. In most cases, weak theories are constructed using vague or imprecisely defined hypotheses …
Burning Torches, Eyes, And Empires: A Visual Rhetorical Analysis Of The Modern American Fascist Aesthetic, Caleb Lawler
Burning Torches, Eyes, And Empires: A Visual Rhetorical Analysis Of The Modern American Fascist Aesthetic, Caleb Lawler
Theses and Dissertations
Allegiance to the ideology of fascism is growing in the United States. Racist, misogynist, and xenophobic sentiments are prevalent throughout far-right groups in America. Despite fighting fascism worldwide in World War I and World War II, powerful American figures have and still hold strong ties to fascism. To consolidate control, fascists construct an aesthetic of themselves and their ideological opponents. Using visual rhetorical theory and Marxist theory, I will conduct three visual rhetorical analyses on three images from modern American political events to examine how the fascist aesthetic expresses itself in different situations.

Evaluating The Use Of The Mobile Electrocardiogram Technology Kardiamobile™ In Community Settings: An Online Survey, Aimee Emmett, Bridie Kent, Alison James, Jane March-Mcdonald
School of Nursing and Midwifery
Background: In response to issues identified by community healthcare professionals (HCPs), including difficulty in routinely recording electrocardiograms (ECGs) at the time of their assessments with the population of patients referred to as ‘housebound’, one National Health Service (NHS) Trust adopted the mobile ECG technology; KardiaMobile™, supported by the Academic Health and Science Network (AHSN), in 2017–2018. The use and uptake of this technology were evaluated and are reported in this paper. Methods: A cross-sectional, mixed-methods online survey was conducted from August 2021 to October 2021. The respondents were a convenience sample of HCPs using KardiaMobile™ to detect atrial fibrillation (AF) …

Faculty, Staff and Students Publications
The assignment of variants across haplotypes, phasing, is crucial for predicting the consequences, interaction, and inheritance of mutations and is a key step in improving our understanding of phenotype and disease. However, phasing is limited by read length and stretches of homozygosity along the genome. To overcome this limitation, we designed MethPhaser, a method that utilizes methylation signals from Oxford Nanopore Technologies to extend Single Nucleotide Variation (SNV)-based phasing. We demonstrate that haplotype-specific methylations extensively exist in Human genomes and the advent of long-read technologies enabled direct report of methylation signals. For ONT R9 and R10 cell line data, we …

Human-Machine Communication
This paper delves into what the application of authenticity to Human-Machine Communication (HMC) can teach us about authenticity and us as HMC researchers and as a com- munity. Inspired by the 2023 pre-conference “HMC: Authenticity in communicating with machines,” two central questions guide the discussion: How does HMC contribute to our understanding of authentic communication with machines? And how can the concept of authenticity contribute to our sense of self as researchers within the HMC field? Through the collaborative effort of 22 authors, the paper explores the re-conceptualization of authenticity and presents recent areas of tension that guide the HMC …

External And Internal Attribution In Human-Agent Interaction: Insights From Neuroscience And Virtual Reality, Nina Lauharatanahirun, Andrea Won, Angel Hsing-Chi Hwang
Human-Machine Communication
Agents are designed in the image of humans, both internally and externally. The internal systems of agents imitate the human brain, both at the levels of hardware (i.e., neuromorphic computing) and software (i.e., neural networks). Furthermore, the external appearance and behaviors of agents are designed by people and based on human data. Sometimes, these humanlike qualities of agents are purposely selected to increase their social influence over human users, and sometimes the human factors that influence perceptions of agents are hidden. Inspired by Blascovich’s “threshold of social influence’, a model designed to explain the effects of different methods of anthropomorphizing …
Feminist Cybernetic, Critical Race, Postcolonial, And Crip Propositions For The Theoretical Future Of Human-Machine Communication, Paula M. Gardner, Jess Rauchberg
Feminist Cybernetic, Critical Race, Postcolonial, And Crip Propositions For The Theoretical Future Of Human-Machine Communication, Paula M. Gardner, Jess Rauchberg
Human-Machine Communication
The authors review theoretical trends in HMC research, as well as recent critical interventions in the HMC journal that usefully reshape and expand our research terrain. Conventional research such as positivist and quantified approaches are identified as restraining research questions and delimiting understandings of concepts including subjects, agency and interactivity. Feminist cybernetic, critical race, postcolonial and crip theoretical approaches are offered, examining how they fill research gaps in HMC, expanding content areas explored, and addressing diverse intersectional pressures, situated, and time/space dynamics that impact human machine interaction. The authors suggest these shifts are essential to expanding HMC research to address …

Machine Ex Machina: A Framework Decentering The Human In Ai Design Praxis, Cait Lackey, Zizi Papacharissi
Human-Machine Communication
Artificial intelligence (AI) design typically incorporates intelligence in a manner that is affirmatory of the superiority of human forms of intelligence. In this paper, we draw from relevant research and theory to propose a social-ecological design praxis of machine inclusivity that rejects the presumption of primacy afforded to human-centered AI. We provide new perspectives for how human-machine communication (HMC) scholarship can be synergistically combined with modern neuroscience’s integrated information theory (IIT) of consciousness. We propose an integrated theoretical framework with five design practice recommendations to guide how we might think about responsible and conscious AI environments of the future: symbiotic …

Forage Productivity Evaluation And Geographic Information Systems In Temperate Semi-Arid Agro-Ecosystem, H Salinas, R Ramirez, J Zegbe, G Medina, R A. Martinez
IGC Proceedings (1977-2023)
700,000 ha of the temperate semi-arid area of Zacatecas state are grown with rainfed crops. Low productivity is obtained from these crops: 350 kg/ha of beans grain and 500 kg/ha of corn grain. This state is characterized by a wide range of topographic and climatic values. A need for alternative crops led to establishment of a trial to evaluate rainfed forages, and to know in what range these could be located. Geographic information systems were used to find out the potential area of the species. Results indicated that sorghum presented a higher yield (5822 kgDM/ha) than sorghum x sudan (5460), …
The Effect Of Harvest Techniques On Yield, Botanical Composition And Soil Structure In An Organic Clover Grass Sward, M Lund
IGC Proceedings (1977-2023)
The objectives of this study were to find out if lighter machines with less number of wheel-passes are favourable for harvesting grassland under wet conditions. A field trial on an ecological experimental farm in Norway was performed with two different mechanization systems. One was a conventional mechanization system with reduced ground pressure tractor driving a forage harvester and grass trailers, and one less wheeling system with reduced ground pressure where a two-wheel tractor with a mower was putting the grass in a swath and a self loading trailer was picking the swath up. The field work was carried out as …

Symbiotic Potential And N Returns In Forage And Grain Legumes For Improving The N Economy Of Tropical Cropping Systems, F D. Dakora, J A. Abdogoba
IGC Proceedings (1977-2023)
There were marked cultivar and species differences in the amounts of N fixed and potential N returns in five forage legumes and ten groundnut (Arachis hypogaea L.) cultivars evaluated for symbiotic performance in both Guinea and Sahel savanna environments. Of the forage legumes, the Crotalaria and Lablab species accumulated greater symbiotic N and therefore showed higher potential N returns for improving the N economy of soils in both Guinea and Sahel savanna in Africa. However, Lablab appeared to be better adapted to the drier Sahel environment compared to the other species. When nutrient imbalances in the Guinea savanna soil …

IGC Proceedings (1977-2023)
The livestock sector contributes about 30% of the total value of agricultural production but the sector does not meet the demand for milk. Currently, there is serious migration of the rural population to urban centres and this will lead to high demand for milk and milk products. Therefore, the development of peri-urban dairy production by the small scale farmers appears a promising option to solve the problems of malnutrition, increase household incomes and improve the quality of life of these farmers. The dominant production system practised is zero-grazing using improved dairy breeds and feeding elephant grass (Pennisetum purpureum) …

IGC Proceedings (1977-2023)
The forage productivity of sole plots of Stylosanthes capitata and Stylosanthes hamata in comparison with various proportional mixtures of the two legumes and their effect on soil properties and subsequent maize yield were studied in subhumid Nigeria. Dry matter (DM) yields in the mixtures were higher than in the sole stands, with the mixtures of S. hamata and S. capitata reaching 11959 to 14822 kg/ha over a three year period. Total nitrogen and/or organic carbon concentrations in the soil following the three years of legume were higher in the mixtures than in the sole stands, and this resulted in higher …

Exploring The Mechanistic Trail Connecting Cellular Function, Health, And Athletic Performance With Phase Angle: A Review On The Physiology Of Phase Angle And Exercise-Based Interventions, Trevor Short, Paulette Yamada
Topics in Exercise Science and Kinesiology
Topics in Exercise Science and Kinesiology Volume 5: Issue 1, Article 7, 2024. Bioelectrical impedance analysis-derived phase angle (PhA) has been widely used in clinical and sports settings, as it is positively associated with health and fitness. However, what PhA is measuring at the cellular level has not been addressed, which limits our interpretation of PhA. The purpose of this review is to provide a roadmap, starting with the mechanistic link between the dielectric properties of mammalian cells and their physiological function. In simplistic terms, PhA measures cellular permittivity and electrical conductivity. These characteristics determine cellular health and function. This …

IGC Proceedings (1977-2023)
The long term seed softening of burr medic (Medicago polymorpha L.) was studied in the field in a mediterranean environment in Chile. Burrs were collected in March of 1988, 1989, 1990 and 1991 (collecting years), and placed in the field either on the surface or buried at 1 cm depth. Field germination was recorded regularly and the remaining non-germinated seeds were tested for germination in the laboratory during 4 years. The percentage of soft seeds on soil surface burrs was on average 3.2% (mean of 4 collecting years) after the first summer in the field, and reached 83% after …

Forage Production In The Rice Fields During Dry Season Ryegrass, White Clover And Oats, A S. Raveloson, E Haraldseide
IGC Proceedings (1977-2023)
In the highland of Madagascar, lack of good forage is very acute during the dry and cool season. The cultivation of temperate forage in rice fields under irrigation is practised by farmers to feed dairycattle. The main forages which are cultivated are oats (Avena sativa), Italian rye grass (Lolium multiflorum) and white clover (. Under experimental conditions rye grass has given the highest yield, but every species have their particularities, which can be useful in forage production. Three varieties of each species were studied in 1993 and 1994. Experiments were carried at five sites in the winter …

Impacts Of Grazed Pastures On Soil Water And Nitrogen Status In Cropping Systems, J A. Baldlock, W D. Bellotti, A D. Moore, I Yunusa
IGC Proceedings (1977-2023)
In southern Australia pastures precede wheat in many rotations. In recent years the quality (legume content) of many pastures has declined and the value of pastures in rotation with cereals has been questioned. This research aims to develop a more complete understanding of the impact of pastures on crop production through greater knowledge of the below ground processes of soil water and soil inorganic nitrogen. In this study, the impacts of annual barley grass (Hordium leporinum) and barrel medic (Medicago truncatula) pastures on soil water and inorganic nitrogen status at the start of a subsequent wheat growing season were investigated …

IGC Proceedings (1977-2023)
A model was developed to simulate a milk production system. The program determines the milk production based on energy nutrition, calving date, cow potential and defines grazing sequence and harvesting dates. It can simulate different stocking rates, paddock sizes, levels of production according to pasture quality, seasonal production and concentrate intake. The output of the model is used for an economical analysis which evaluates costs and returns; for some of the most sensitives factors that affect economic returns like prices of milk and concentrate, pasture production and others. The program makes an analysis of sensitivity where these factors are varied …

Yield Decrease Of Corn Sown Into Italian Ryegrass By Minimum Tillage, R Kobayaski, K Tateno, S Sato
IGC Proceedings (1977-2023)
The objective of this study was to determine the factor causing yield decrease of corn (Zea mays L.) sown into Italian ryegrass (Lolium multiflorum Lam.) by minimum tillage. 5 plots with 2 replications were made, consisting of the number of harvest times of Italian ryegrass, tillage system, and herbicide application. They were 1CT (Italian ryegrass was harvested once/conventional tillage), 1MT (once/minimum tillage), 1MTH (once/MT/herbicide), 2CT (twice/ CT), and 2MT (twice/MT). 1MT produced lowest corn yield and highest Italian ryegrass litter. This observation suggested that corn yield decrease was attributed to competition with Italian ryegrass regrowth. NAR in 1MT …
