Methods On Implementing Radar And Antenna Solutions To Defense And Biomedical Problems, Jalexis E. Vanga Guzman

College of Graduate Studies: Theses & Dissertations

Growing developments in antenna and radio frequency systems have created a strong incentive for researchers to study and apply electromagnetic (EM)-based solutions to modern defense and biomedical problems. The ability to transmit and receive EM waves using antenna systems has not only increased global connectivity, but also increased the need for innovation in antenna size reduction and development of radar systems.

Size reduction techniques have been extensively studied for antennas after the development of electrically small antennas (ESAs) which follow Chu’s limit. ESAs allow the implementation of antennas with much smaller foot-size than traditional full-sized designed while keeping the same …

The Relationship Between Age, Sport, And Years Coaching On Knowledge, Confidence, Preparedness, And Intention To Intervene With Youth Athletes Experiencing Mental Health Challenges, Allyson P. Looby

College of Graduate Studies: Theses & Dissertations

Introduction: Mental disorders can affect all ages and populations, but there is an increasingly high prevalence in the pediatric population. It is estimated that 1 in 5 youth between the ages of 9-17 experiences some degree of impairment from a diagnosable mental health disorder (Merikangas et al., 2010). Youth are often not equipped to seek professional support; making parents, teachers, and coaches key to detection and referral to professional help (Ng et al., 2021). The environment youth sports creates gives coaches the opportunity to have a greater impact on youth mental health (Das et al., 2016). Purpose: Determine if age, …

Emergency Preparedness And Response: Examining Rural Hospitals (Rhs) Communication Systems Before, During, And After A Natural Disaster, Geremy D. Lloyd

College of Graduate Studies: Theses & Dissertations

Introduction: Rural Hospitals (RHs) have distinctive characteristics that constitute unparalleled challenges. One of those challenges is the ability to communicate effectively in a disaster, impacting the various effects on the affected society. Research has shown that effective emergency preparedness and response (EPR) communication is paramount when communicating informed details about emergent events. Despite the evolving complexities of communication and the technology associated with disaster communication, very few studies have successfully investigated RHs communication systems before, during, and after a natural disaster. The purpose of this study was to examine and assess RHs communication systems and to highlight the strengths, identify …

Investigating Salinity Intrusion Effects On Sapelo Island, Georgia Using Benthic Macroinvertebrate Bioindicators, Raymond Paul Kidder Ii

College of Graduate Studies: Theses & Dissertations

Coastal wetlands are threatened by the compounding effects of sea level rise and historical land modification. Historically, much of Sapelo Island, Georgia was deforested and drained using a series of ditches and canals to create arable land fit for agriculture and to provide drainage to the inhabited parts of the island. Today, this network of artificial channels is believed to be facilitating the movement of saltwater from the nearby estuary into freshwater areas on the interior of the island. This study aimed to better understand the frequency and magnitude of salinity intrusion events along with their resulting impacts to the …

Child Sexual Abuse Cases In The Catholic Church Vs. Secular Groups: A Media Content Analysis, Hannah G. Adkison

College of Graduate Studies: Theses & Dissertations

Child sexual abuse (CSA) is a serious public health problem in the United States, with estimates suggesting that approximately 8% of males and 20% of females experience some form of sexual violence before adulthood (Pereda et al., 2009). Adult acquaintance victim-offender relationships account for 83% of all cases (Ullman, 2001). And while the acquaintance of victim- offender relationships is facilitated by a range of social institutions, perhaps none have received as much media attention as those occurring in the context of the Catholic Church (Formicola, 2014). Although child sexual assault is recognized as a serious punishable charge in all 50 …

Blockchain Securities Issues: Decentralized Identity System With Key Management Perspective, Olalekan O. Adaramola

College of Graduate Studies: Theses & Dissertations

Blockchain was created many years ago to solve the problems of data transfer Integrity, several years later the issues persist.

Eating Disorders: Barriers To Peer And Self Recognition And The Ability To Seek Or Give Help, Savannah Mcvey

Honors College Theses

A lack of knowledge concerning eating disorders has been found to play a major role in self-recognition, peer recognition, and barriers to seeking treatment at all. More specifically, straight men were more often not able to identify these issues in themselves or others. Theories that have been presented involve the image of eating disorders being a “woman’s issue” and a possible obsession with weight lifting and changing one’s body to take on a more masculine build. Combatting this issue needs to begin in the form of basic education on college campuses due to the prevalence in this particular age group. …

“I Tell My Brothers That It Can Be Done”: Indigenous Males Navigating Elite Australian Higher Education, Garth Stahl, James A. Smith, Andrew Harvey, Braden Hill, Himanshu Gupta, Sam Moore, Jianing Wang

Research outputs 2022 to 2026

As Australian higher education grapples with its colonial history, there has been significant attention to recruiting Indigenous students. However, while we have seen increases in Indigenous participation, males lag significantly behind. Very few Indigenous males enter university and even fewer enter the upper echelons of the stratified higher education sector. In this paper, we investigate the experiences of four Indigenous young men who attended an elite Australian higher education institution. Central to our analysis is how their identities are realised in relation to their sense of Indigeneity and Western ways of knowing, being and doing. In capturing the complex identity …

The Negative Relationships Between Employee Resilience And Ambiguity, Complexity, And Inter-Agency Collaboration, Geoff Plimmer, Joana Kuntz, Evan Berman, Sanna Malinen, Katharina Näswall, Esme Franken

Research outputs 2022 to 2026

Employee resilience (ER) is often needed to face demands inherent in public sector work. Some types of demands, however, may hinder its development, rather than provide the type of challenging adversity from which resilience can develop. Public sector job demands have been a long-standing issue for public workplaces and employees but are also growing in salience as organisations face an increasingly variable, uncertain, complex, and ambiguous environment. Drawing on the Job Demands–Resources model and the challenge/hindrance stress literature, this multi-level study of Aotearoa New Zealand civil servants (n = 11,533) in 65 public sector organisations shows that ER is negatively …

Unmasking Microaggressions On The Homefront: Exploring Faculty And Staff Perceptions After Attending An Online Workshop On Microaggressions In Higher Education, Andrea N. Crenshaw, Natasha N. Ramsay-Jordan, Allyson Deskins

Georgia Educational Researcher

Microaggressions are brief and everyday slights, insults, indignities, and denigrating messages sent to people of color and/or marginalized groups (women, LGBTQ+, etc.) by well-intentioned [people] who are unaware of the hidden messages being communicated (Sue et al., 2007). Microaggressions are connected to broader conceptualizations of the impact of implicit bias and systems of inequity. Specifically, in K-12 and higher education, microaggressions impact the physical, social, and emotional well-being of those who experience them. Growing research posits the need for more discussions in education about racism, sexism, and other bias prevalent in the field of education (Bergerson, 2003). As such, some …

Novel Therapeutic Approaches To Treat Brain Cancer Combining 3d Cell Culture Models, Cold Atmospheric Plasma And Airborne Acoustic, Janith Wanigasekara

Doctoral

Glioblastoma (GBM), an adult-type diffuse grade 4 glioma (IDH wild type), is the most prevalent, aggressive, fatal, highly vascularized, malignant primary brain tumour in adults with a poor prognosis. Despite existing therapies such as surgical resection, radiation therapy and chemotherapy such as temozolomide (TMZ), patient survival remains largely unchanged over the last three decades. There is an urgent need for novel and effective therapeutic strategies that can overcome drug resistance, cross the blood brain barrier, and minimise off-target side effects that can negatively impact a patient's quality of life. The high failure rate of clinical trials is due to inefficient …

Analysis Of Hippo Pathway Signalling In Schwannoma And Meningioma, Julio Grimm De Guibert

Peninsula Medical School Theses

This project focuses on two tumours of the nervous system, schwannoma and meningioma. A large group of schwannomas and meningiomas display the inactivation of the NF2 gene. The NF2 gene codes for the tumour suppressor protein Merlin and its loss is associated with a multitude of pro-tumourigenic mechanisms leading to the occurrence of schwannomas and meningiomas. The loss of Merlin function causes augmented Hippo signaling i.e. interaction of YAP and TAZ, both co-activators of gene expression and the two main effectors of the Hippo signalling pathway, and TEAD, a group of transcription factors binding to YAP and TAZ. There resulting …

Investigation Of Microbiome Metabolites And Mitochondrial Function In A Model Of Non-Alcoholic Fatty Liver Disease, Paula Boeira

Peninsula Medical School Theses

Several dietary metabolites produced by gut bacteria have been linked to disease including non-alcoholic fatty liver disease (NAFLD). Trimethylamine N-oxide (TMAO) and phenylacetic acid (PAA) are microbiome-derived metabolites that have been associated with early onset of NAFLD. Hypothesising that these metabolites contribute to lipid deposition in the liver by altering hepatic mitochondrial function, we assessed how TMAO and PAA affect hepatocyte bioenergetics in cell models of liver steatosis. Proliferative and differentiated HepaRG cells were cultured under standard conditions, and steatosis was established by 48h exposure to oleate and palmitate (2:1 molar ratio). Lipid accumulation was assessed by BODIPY™ staining and …

Evaluation Of Mir-497 & Mir-219 As Non-Invasive Biomarkers For Meningioma And Glioma, Ahmed Abdelrahman

Peninsula Medical School Theses

Introduction: The current WHO classification aids in predicting meningioma and glioma recurrence and prognosis. However, there is a dearth of circulating biomarkers with clinical value for meningioma diagnosis and classification. Circulating miRNAs have shown potential as cancer biomarkers in various tumours. This study evaluated specific miRNAs, miR-497 and miR-219, as convenient and efficient predictors of meningioma and glioma grades. MiR-497 was selected based on preliminary results from Professor Hannemane's group, indicating its potential as a meningioma biomarker. MiR-219 was chosen because of its reported differential expression according to meningioma grade. Methods: Serum and exosomal levels of miR-497 were studied in …

Anastomotic Leakage In Rectal Surgery: Where Are We And Where Do We Go From Here?, Benjamin William Peter Rossi

Peninsula Medical School Theses

Anastomotic leak in colorectal surgery is a significant complication which is feared by surgeons and has considerable consequences for patients. It affects up to 17% of rectal resections and although there is significant knowledge regarding its detection and treatment, there are still no reliable methods for its prevention. We proposed the routine use of intra-operative endoscopy as a method of reducing the risk of anastomotic leak. This thesis explores current knowledge regarding anastomotic leaks, including the causes, prevention and management. We also present the findings from a feasibility trial into intra-operative endoscopy as a method for reducing anastomotic leak rate. …
