Changes in plankton have important implications for ecosystem services, including supporting fish stocks, carbon sequestration, nutrient cycling, and oxygen production. Standard long-term plankton monitoring relies on light microscopy to identify and count plankton taxa, with methods fully supported by international standards, providing high quality trusted data. Novel methods, including imaging and molecular, offer means of collecting select types of plankton data efficiently, filling targeted knowledge gaps left by standard monitoring and generating a more complete picture of plankton dynamics. Standard and novel monitoring methods present different advantages and costs, positioning their suitability to address different management needs. Standard plankton monitoring …

Social Exclusion Of Refugees With A Disability In Australian Society Within The Context Of Healthcare Quality Theory And E-Health, Hossein Adibi

Research outputs 2022 to 2026

The phrase social exclusion came to Australia via Britain. Discussion on 'inclusion and exclusion' mainly focus on those individuals and groups living in poverty. Socially excluded occurs as a result of many factors, based on sex, race, ethnic origin, religion, sexual orientation, and disability. Until 2012 people with a disability were excluded from Australian' resettlement programs representing a significant discrimination concern. As a result of strong opposition to this issue, the policy changed in 2012 and the number of refugees with disabilities increased. This in turn led to more ethnic diversity of people with disabilities within NDIS. However, since NDIS …

Educator Professional Subjectivities In Gamification: Knowing, Being And Doing, Natalie-Jane Howard, Elizabeth J. Cook

Research outputs 2022 to 2026

Gamification has emerged as a prominent innovation in contemporary education, yet its influence on the enactment of educators’ professional subjectivities remains underexplored. As such, little is known about how online gamification applications like Kahoot shape the dynamic ways educators perceive, understand and enact their professional selves within higher education contexts. Adopting a tripartite framework of knowing (epistemological), being (ontological) and doing (praxiological), this qualitative study employed visual-elicitation interviews and remote observations with ten lecturers at a Middle Eastern college. The analysis revealed three key themes shaping educator subjectivities: creating and sharing quiz content; conforming with institutional culture; and infantilizing students …

Improving Hpv Vaccine Rates For Aboriginal Young People Through A Social Media Campaign: An Interrupted Time Series, Natalie A. Strobel, Jocelyn Jones, Kim Gates, Simon L. Turner, Joanne E. Mckenzie, Daniel R. Mcaullay

Research outputs 2022 to 2026

Human papillomavirus (HPV) is a common sexually transmitted infection that can lead to HPV-related cancers such as cervical cancer and other cancers such as anal, vaginal, and penile cancer. HPV rarely produces symptoms and cannot be cured or treated; therefore, vaccination is essential to protect against HPV and HPV-related diseases. However, young Aboriginal and Torres Strait Islander (hereafter, respectfully, ‘Aboriginal’) people are not receiving their HPV vaccine dose, resulting in missed opportunities to be protected from HPV-related cancers. Health promotion is a critical way to empower people to take ownership over and control their health and is a core function …

A Computational Fluid Dynamics (Cfd) Based Assessment Of Animal Borne Data Logger Impact, Christopher Pass

School of Engineering, Computing and Mathematics Theses

Animal borne data loggers are powerful tools that provide researchers with valuable insight into the behaviour and ecology of free-ranging marine animals. Despite their usefulness, the addition of a tag inevitably alters the forces acting on a swimming body and can increase the energetic cost of swimming. Computational Fluid Dynamics (CFD) tools offer a powerful means of assessing tag impact and a number of previous works have employed CFD to this end but have typically been based on a range of simplifying assumptions. Chief amongst these simplifications is that animals can be modelled as rigid bodies with a simple tag …

Meditation Techniques And Their Relationship To Psychotic-Like And Mystical Experiences, Timothy Palmer

School of Psychology Theses

Meditation practice has been associated with benefits but also adverse experiences from anxiety to psychotic-like experiences (PLEs) and even psychosis. The overarching aim was to identify how different types of meditation techniques (varying in bodily focus) differentially relate to psychotic-like experiences and cognitive abilities, including interoceptive awareness, affective awareness and decision-making. For this, I conducted two correlational studies and an intervention study.Different systems have been proposed for classifying meditation techniques. Nash et al’s (2013) approach categorises techniques by goal: Null Directed Methods (NDM), which aim for an “empty” state; Cognitive Directed Methods (CDM), aimed at an enhanced cognitive state; and …

Predictive Perception In Autism, Robert Harlow

School of Psychology Theses

This thesis investigates how predictive perception, motor coordination, and neurotype differences influences social perception in autism. It explores how these mechanisms contribute to social difficulties faced by autistic people, through the lens of the double empathy problem and second-person neuroscience.Chapter 2 examined how spoken intentions and visual evidence guide predictive social perception. Across four experiments, results supported a dual-process model whereby top-down expectations shape early perception but are overridden by visual input once motion begins. This led to the ‘kinematic dominance hypothesis’, suggesting motion cues dominate perception once movement begins due to their higher precision.Chapter 3 used high-resolution active motion …

Understanding Truth And Reconciliations Processes In An Art-Based Community Project Which Addresses Experiences Of Iatrogenic Harm In Mental Health Services, Joseph French
