Teaching Digital Evangelism And Web Design As Redemptive Work For The Women Of The Northeastern Conference Of Seventh-Day Adventists, Brenda Michele Rhyne

Doctor of Ministry Projects

Problem.

The COVID-19 pandemic eliminated thousands of jobs, including positions held by women within the Northeastern Conference of Seventh-day Adventists. Unemployment and underemployment may contribute to diminished self-esteem and adverse mental-health outcomes. The problem of unemployment and underemployment is not simply economic—it is theological. For women in the Northeastern Conference, the lack of an ordered pathway to explore technology-related fields as a career option represents both an economic and a spiritual loss. A course combining technical and evangelistic training may promote members' involvement in evangelistic initiatives (i.e., TMI) while simultaneously providing technological skills. Also, women who do not regularly use …

Fault Tolerant Adaptive Control Under Actuator Saturation For Robot Manipulators, D. J. López-Araujo, N. Alvarez-Jarquin, P. Borja, A. T. Becker

School of Engineering, Computing and Mathematics

In practice, actuators inherently have natural limitations that are often overlooked by theoretical control strategies, such as bounded output and discrepancies between calculated and actual responses. Consequently, reliable control techniques must be employed to ensure safe and dependable operation. We propose an adaptive control law for global regulation in the case of partial loss of effectiveness due to input faults. The proposed control strategy maintains the system at the desired configuration while accounting for the physical limitations of the actuators. Additionally, it is suitable for dealing with unknown parameters in the vector of gravitational forces, making it robust to these …

Angle-Based Formation Stabilization And Maneuvers In Port-Hamiltonian Form With Bearing And Velocity Measurements, Ningbo Li, Pablo Borja, Arjan Van Der Schaft, Jacquelien M.A. Scherpen

School of Engineering, Computing and Mathematics

This paper proposes a port-Hamiltonian approach for angle-based formation stabilization and maneuvers using bearing and velocity measurements with an underlying triangulated Laman graph. The corresponding port-Hamiltonian controller is designed using virtual couplings on the errors of angle constraints in angle space. Then, the angle constraints and agent actuators are mapped by the constraint Jacobian, which can be applied to other formation constraints. In addition, to avoid unavailable distance terms in the control law, an estimator is designed based on port-Hamiltonian theory and the property that energy is coordinate-free for different sensor modalities using bearing and velocity measurements, which permits our …

Specifically, it presents a single-stepapproach to functionalize the 3D graphene foam (Gii-Sens) with 1-pyrenebutyric acid N-hydroxysuccinimideester (Pyrene-NHS ester). Electrochemical techniques, including cyclic voltammetry (CV) and differential pulsevoltammetry (DPV), confirmed …


Shelled Shut-Ins: A Conditional Escape Task Showing Perceptual Awareness In Hermit Crabs, Ari Drummond, John Spicer, Mark Briffa Jan 2026

Shelled Shut-Ins: A Conditional Escape Task Showing Perceptual Awareness In Hermit Crabs, Ari Drummond, John Spicer, Mark Briffa

School of Biological and Marine Sciences

Sentience is an increasingly popular topic in animal welfare and behavioural research. However, studying sentience can be difficult and contentious. Sentience has frequently been associated with ‘feelings’ and ‘subjective states’ not directly accessible to human observers; thus, investigating awareness in animals could be an alternative approach. Frameworks of awareness have been developed for the experimental examination of cognitive capacities that might underpin ‘feelings’ as affective states and subjective experiences. Using a framework of four hierarchically arranged levels of awareness (that is, perceptual, cognitive, assessment and executive), the awareness of an intertidal crustacean, the common hermit crab, Pagurus bernhardus , was …

Picturing The Past: The Role Of Photo Cue Visual Perspective On Positive Autobiographical Memory Recall In Dysphoria, Sarah Snow, Zachary Adolph Niese, Julie L Ji

School of Psychology

Positive autobiographical memory plays a key role in emotional well-being and is distorted by cognitive processing biases in dysphoria. This experiment investigated how the visual perspectives (first-person vs. third-person) of personal photographs influence recall of positive memories depending on dysphoria. Eighty-five participants (42 low dysphoria, 43 high dysphoria) submitted photos of positive events from both perspectives. Later, participants recalled these events while viewing either a first- or third-person photo before rating and describing their memory. While first-person photos promoted more recall from an own-eyes vantage point regardless of dysphoria level, dysphoria was still associated with greater observer-like recall, reduced mental …

UNF Graduate Theses and Dissertations

Using first-principles methods, we investigate the effects of applied isotropic pressure on the electronic and magnetic properties of intercalated Fe1/3TaS2 and Co1/3TaS2. Fe1/3TaS2 has been shown to be a ferromagnet that undergoes structural and magnetic phase transitions under applied pressure. The magnetic phase transitions are observed to be linked to the structural shift, and a mixture of magnetic phase states is present between 3 GPa and 6 GPa. Co1/3TaS2 was found to be antiferromagnetic, as confirmed by experimental work. One- and two-unit-cell systems of Co1/3TaS2 are analyzed, both showing band splitting that disappears under pressure. The application of pressure forces …

UNF Graduate Theses and Dissertations

Teacher shortages have increased in the past two decades, creating greater emphasis on recruitment, talent development, and retention efforts for educational leaders. Novice educators feature prominently in these considerations. A teacher’s first years can be extremely challenging, and induction, the professional learning experiences specific to early career professionals, is often considered the answer. Despite the seeming ubiquity of induction, there is much variability in interpretation, enactment and outcomes. While it is generally accepted that some induction is better than no induction, new teachers deserve more intentionally designed support.

This study sought to reexamine assumptions about induction, adding to the literature …
