Interactions Between Traditional And Reversed It Adoption: How Incumbent Devices Affect Cross-Situational Specialization Of New Entries, Christopher Agyapong Siaw, Jack Cadeaux, Dirk Meissner, Adrian Payne, David Sarpong

Plymouth Business School

This article proposes a cross-situational specialization framework for what, at its introduction, was a newer generation personal computer (PC) device (a tablet computer). With use as the basis for continuance adoption as the theoretical lens, this article explores how the tablet coexists as a substitute- and a complement-in-use with incumbent PC(s). To test a model consisting of cross-situational use patterns, determinants, and outcomes, this article develops and analyzes the results of a survey of tablet computer use in a learning and education context. The results show a stronger coexistence between the tablet and the incumbent devices when the devices perform …

The Effect Of Water Flow Rates On The Survival And Growth Rates Of Three Caribbean Bouldering Coral Species Juveniles In An Indoor Versus Outdoor Environment, Ian Michael Johnson

All HCAS Student Capstones, Theses, and Dissertations

Coral reefs are vital ecosystems for the world’s oceans and humanity; however, they are threatened by climate change, disease, and local anthropogenic stressors, and need assistance to recover. Traditional reef restoration efforts (fragmentation and outplanting are helping but are limited in effectiveness by not increasing genetic diversity. Ex situ sexual propagation for corals provides new, genetically different coral recruits. However, this process is laborious, expensive and time consuming, especially at the scale required to effectively contribute to the widespread recovery. To lower costs, two key parameters that require optimization to hasten the growth of coral recruits are water flow and …

Applying Integrative Systematics To The Poorly Explored Symbiotic Relationships Between Echinoderms And Zoanthidea, Savannah Renken

All HCAS Student Capstones, Theses, and Dissertations

Epizoic Zoanthidea are highly diverse and live symbiotically with at least six invertebrate phyla, but little is known about zoanthideans living on urchin spines. To better understand symbiotic interactions between Echinodermata and Zoanthidea, Atlantic deep-sea Cidaridae urchin specimens from five museums were surveyed to characterize Zoanthidea colonies on their spines. Specimens were obtained from the Gilbert and Nancy Voss Marine Invertebrate Collection at University of Miami, the Florida Museum Invertebrate Zoology Collection, and the collections of James Reimer and Hiroki Kise at the University of the Ryukyus. This research uses an integrative approach to species discovery and systematics. Integrative systematics …

Optimization Of Light Spectrum During Coral Grow-Out, Daisy N. Ponce

All HCAS Student Capstones, Theses, and Dissertations

Direct and indirect anthropogenic stressors have led to a global decline of coral populations. Coral restoration aims to mitigate this loss and facilitate reef recovery. In particular, the sexual propagation of corals ex situ allows for the production and outplant of genetically diverse coral recruits on the reef. However, optimization at ex situ coral nurseries is required to scale-up production. This project aims to investigate and develop methods that reduce the duration of grow-out ex situ by determining the optimal light spectrum under which to rear for sexual recruits of the tropical scleractinian coral species Pseudodiploria strigosa and P. …

The Language Of League: Making Sense Of Multimodal Meaning In Twitch Live Streams, Dena Elisabeth Arendall

Electronic Theses and Dissertations Archive

Though there has been a good deal of research on digital discourse and online gaming, there has been relatively little research on 1) the social structure of specific groups within the large online gaming community, 2) the multimodal structure of the online gaming live stream, and 3) the impact that these structures have on the final communicative event. One noteworthy component of the social characteristics of online streams is the streamer gender and size of the stream’s audience. In addition, one difference that sets the live stream apart from other online communications is its intense technological complexity. This study then, …

Vertical Federated Learning Using Autoencoders With Applications In Electrocardiograms, Wesley William Chorney

Theses and Dissertations

Federated learning is a framework in machine learning that allows for training a model while maintaining data privacy. Moreover, it allows clients with their own data to collaborate in order to build a stronger, shared model. Federated learning is of particular interest to healthcare data, since it is of the utmost importance to respect patient privacy while still building useful diagnostic tools. However, healthcare data can be complicated — data format might differ across providers, leading to unexpected inputs and incompatibility between different providers. For example, electrocardiograms might differ in sampling rate or number of leads used, meaning that a …

Signings Of Graphs And Sign-Symmetric Signed Graphs, Ahmad Asiri

Theses and Dissertations

In this dissertation, we investigate various aspects of signed graphs, with a particular focus on signings and sign-symmetric signed graphs. We begin by examining the complete graph on six vertices with one edge deleted ($K_6$\textbackslash e) and explore the different ways of signing this graph up to switching isomorphism. We determine the frustration index (number) of these signings and investigate the existence of sign-symmetric signed graphs. We then extend our study to the $K_6$\textbackslash 2e graph and the McGee graph with exactly two negative edges. We investigate the distinct ways of signing these graphs up to switching isomorphism and demonstrate …

Evaluation Of The Virulence Potential Of Avian Pathogenic Escherichia Coli Isolated From Broiler Breeders With Colibacillosis In Mississippi, Jiddu Joseph

Theses and Dissertations

Avian pathogenic Escherichia coli (APEC) is a bacterium that is responsible for colibacillosis in birds. However, information about broiler breeder APEC isolates is limited, but the data is critical due to the transfer of this bacteria down the production pyramid to progenies resulting in high mortality. Therefore, we evaluated the phenotypic virulence characteristics of 28 isolates using embryo lethality and day-old chick challenge assays. Also, the in vitro adhesion and invasion potential of selected nine isolates were identified. Results showed more than 1/3^rd of the isolates were highly virulent and the virulence increased as the number of virulence-associated genes …

Evaluation Of Heat Abatement Use, Vaginal Temperature, And Activity Of Pregnant, Lactating Holstein Cows Housed On Pasture With Or Without The Choice Between Shade And Sprinklers For Heat Abatement., Kevin M. Braman

Theses and Dissertations

The objective of this thesis was to determine how pregnant, lactating Holstein cows on pasture interact with shade and sprinklers when offered a choice or no-choice between methods. Authors hypothesized that cows would use shade more then sprinklers, but sprinklers would be more effective at cooling cows. Additionally, authors predicted cows using shade more would have decreased lying bouts and steps and an increase in time lying, compared to cows choosing sprinkler. Results indicate cows will use both methods when offered alone or together. However, cows will choose to be exposed or in shade at lower temperature humidity index values, …

Synthesis And Characterization Of Redox-Noninnocent Pyrazine(Diimine) Iron Complexes And An Inverted Pyridine(Diimine) Ligand, Jaylan Billups

Theses and Dissertations

Cooperativity between the metal center and the ligand has been shown in nature to be an important feature of systems that catalyze two-electron processes that first-row transition metals usually cannot catalyze on their own. In these cases, the ligand acts as a site of reactivity that in many instances can store electrons or react directly with substrates in solution. The design and study of systems where there is synergy between the metal and the ligand have been leveraged to catalyze polymerization and hydrogenation-type reactions as well as the activation of small molecules such as dihydrogen. Specifically, the pyridine(diimine) ligand scaffold …

The Interaction Between Predation And Sound Pollution On The Internal And External Microbiome Of The Grasshoppers Melanopus Sanguinipes, Alanna Bond

Theses and Dissertations

Anthropogenic activities such as construction and agriculture directly affect its surrounding environments. Many studies have focused on how megafauna and flora are impacted by human activities, however, relatively little is known how new occupation of land affects smaller organisms such as insects and microbes. Additionally, other stressors such as predation can impact host physiology. The grasshopper species Melanopussanguinipes was chosen to be used in a study to measure how stress caused by artificial sound and predation can alter exoskeleton and gut microbiomes once exposed to these stressors.

Molecular Mechanisms Of Novel Brain-Penetrating Oxime Acetylcholinesterase Reactivators On Sarin Surrogate-Induced Toxicities, Darby Caroline Stanford

Theses and Dissertations

Organophosphorus compounds (OPs), both nerve agents and insecticides, may induce damage leading to long-term neurological deficits. Oxime 20, the lead compound from a platform of substituted phenoxyalkyl pyridinium oximes (US Patent 9,227,937), is an oxime that reactivates OP-inhibited acetylcholinesterase (AChE) and has displayed neuroprotection within the brain of rats in in vivo tests where the currently approved treatment, pralidoxime (2-PAM), has not. This research investigated the neuroprotective effect of novel oxime therapy. Gene expression in rat piriform cortex was analyzed to determine if neurotoxicity, stress, and synaptic plasticity-associated genes were down-regulated by Oxime 20 following a sublethal dose of sarin …

Dune To Shore: The Relationship Between Vegetative Dune Systems And Shoreline Stability In Barrier Islands, Walter Hastings Hogue

Theses and Dissertations

Dauphin, Petit Bois, and Horn Island form the Alabama gulf-barrier chain directly south of Mobile Bay. Many studies have targeted local climate stressors and the flux of longshore currents as factors for erosional and accretional changes on these islands, but little attention is paid to the degradation of their vegetative dune-systems as a contributor to their shoreline morphology (Hanley et al., 2014; Smith, 2018; Byrnes, 2010). This study fills this literary gap, utilizing GIS raster classification and Digital Shoreline Analysis System to measure vegetative health and shoreline change on these islands and verify a relationship between these two factors. The …

Pre-Emergence Herbicide Programs For Weed Control In Soybean (Glycine Max) And The Effect Of Rainfall Amount On Herbicide Activity, Caleb Knox Meyer

Theses and Dissertations

Preemergence (PRE) herbicides are used to control weeds and reduce pressure on postemergence (POST) herbicides. However, knowledge of length of control each herbicide provides, as well as the amount of activation rainfall required for adequate weed control, is unknown in Mississippi soybean production. Twenty-one PRE applied soybean herbicides were evaluated for their duration of residual control for five weeks over twelve site years on three weed species from 2021-2022. Some differences in control following herbicide application used on certain weed species were observed at different times. However, most PRE herbicides resulted in adequate (greater than or equal to 90%) control …

Nanoscale Modeling Of Membrane Systems Under Mechanical Deformation In Traumatic Brain Injury Using Molecular Dynamics, Anh Thi Ngoc Vo

Theses and Dissertations

Neuronal membrane disruption and mechanoporation are nanoscale damage mechanisms that critically affect brain cell viability during traumatic brain injury (TBI). These nanoscale cellular impairments are elusive in experiments and necessitate in silico approaches such as molecular dynamics (MD) simulations. Implementing MD, this research aims to investigate the effects of different key factors related to membrane deformation and damage, including force field resolutions, lipid compositions, and loading conditions.

To examine the impact of force field resolution, MD deformation simulations were conducted on 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphatidylcholine (POPC) lipid bilayer membranes, using all-atom (AA), united-atom (UA), and coarse-grained Martini (CG-M) force fields. The mechanical responses …

37.3 million Americans (11.2% of the US population) currently have Type 2 diabetes mellitus (T2DM) with over 1.5 million new cases being diagnosed each year. The multifactorial etiology of the patient having neuropathy, overweight/obesity, foot deformities, ischemia, and infection leads to a condition called diabetic foot ulcer (DFU). One in six patients with a DFU will require amputation with infected DFUs have a 155-fold increased risk of amputation. Staphylococcus aureus is the most common bacteria isolated from severe DFU infections that require amputation. Interestingly, diabetics are more heavily colonized with S. aureus compared to non-diabetics suggesting a unique advantageous adaptation …

The Cosolvent And Association Effect On Polymer Behaviors, Xiangyu Zhang

Theses and Dissertations

The blending or mixing is extensively utilized in diverse processes of polymers to bring about advantageous properties, but the behavior becomes intriguing when associations are involved and multi-solvents are used. Explanations based on chemistry-specific arguments are less than satisfactory in abstracting essential features, and lack the general applicability across various systems. So, this work focuses on capturing the physical force governing the phenomenon of interest by using a generic model. Highly non-trivial behaviors of polymers are often observed in multi-solvent solutions. It is known that polymers swell and dissolve in good solvents, while they tend to collapse and aggregate in …
