Seedling Xylem Anatomy Of Two Banksia Species Relative To Availability Of Groundwater, Melissa Karlinski

Theses: Doctorates and Masters

Fluctuating environmental conditions place plants at risk of mortality if they cannot adapt, particularly to warmer temperatures and drier environments. Plants are known to modify their morphology, physiology and anatomy to thrive under these conditions, and xylem anatomy and hydraulic architecture are common traits studied to understand plant adaptations and responses to changeable water availability. However, little is known about the changes to the hydraulic architecture of groundwater dependent plants during their early establishment in water-limited environments. By exposing young seedlings of two Banksia species to contrasting groundwater availability treatments in a glasshouse experiment, it was possible to analyse the …

Video Cued Teacher Reflection To Guide Enhancement Of Student Engagement In A Specialist Primary Classroom, Tamara Nicole Standley

Theses: Doctorates and Masters

Specialist primary teachers confront the challenging task of teaching extensive learning content of the Western Australian Curriculum, within limited weekly timetabled lessons. This was the motivating factor behind this study aimed at investigating the use of self-tracking video technology as a tool for teacher reflection, to guide enhancement of student engagement and learning in the specialist classroom. Reflective practice is integral to monitoring and improving teaching pedagogy but without an effective reflection tool, it can potentially be a waste of time.

The capacity for a teacher to engage in reflection-on-action through real time video analysis enables a deeper understanding of …

The Impact Of Video As A Self-Reflective Tool For Improvement Of Teacher Feedback Practices, Julia Mueller

Theses: Doctorates and Masters

Teacher reflection on instructional practices can improve performance and positively influence student achievement. This qualitative quasi-ethnographic study investigated the impact of self-tracking video technology as a reflective tool for improvement of teacher feedback in a specialist primary classroom. Video provided observational data which was analysed using a checklist and researcher and reviewer annotations. The study concluded that the teacher used non-specific feedback strategies more than specific-feedback to respond to behavioural, engagement and learning issues. Thus, context was identified as an important determinant of effectiveness in feedback. The video technology features enhanced the teacher’s reflection and strengthened the collaborative reflective processes.

Mobility Management In 5g Heterogeneous Networks, Mohammad Arifin Rahman Khan

Theses: Doctorates and Masters

In recent years, mobile data traffic has increased exponentially as a result of widespread popularity and uptake of portable devices, such as smartphones, tablets and laptops. This growth has placed enormous stress on network service providers who are committed to offering the best quality of service to consumer groups. Consequently, telecommunication engineers are investigating innovative solutions to accommodate the additional load offered by growing numbers of mobile users.

The fifth generation (5G) of wireless communication standard is expected to provide numerous innovative solutions to meet the growing demand of consumer groups. Accordingly the ultimate goal is to achieve several key …

Ancient Origins Of A Diverse Stygofaunal Group: The Australian Bathynellidae (Crustacea), Giulia Perina

Theses: Doctorates and Masters

Research on subterranean fauna on all continents has highlighted often high levels of endemism, for both troglobionts (terrestrial subterranean organisms) and stygobionts (organisms living in groundwater). In Australia, particularly in the arid zones of Western Australia, a rich hypogean assemblage has been discovered in the past few decades, largely due to surveys required as part of environmental impact assessments for, and imposed conditions on, mining operations. Bathynellidae (Crustacea) are part of the stygofaunal community, but to-date they are poorly understood, mainly because their conservative morphology, small size and delicate exoskeleton make their dissection, observation and study very difficult. Additionally, the …
