title: Visualising Location-Based Information using Augmented Reality

authors: Zhang, Qimo

subjects: Narrative Navigation

abstract: The use of augmented reality extends navigation in location-based mobile applications. This thesis introduces the concept of narrative navigation and describes the design and testing of four mobile application prototypes that explore the proof-of-concept for narrative navigation. 
We explored the work related to Augmented Reality and navigation and found that no scholars have focused on the use of Augmented Reality by navigating users in the context of location-based stories. This thesis aims to answer the research question of how Augmented Reality visualisations can reflect location-based data to tell a story on mobile devices. While typical navigation only involves guidance to a single point, narrative navigation requires navigation that focuses on the linearity of the story. The goal of our research is to investigate how augmented reality can be used to visualize location-based information for navigation in a storytelling environment.
We carried out the design, development, and testing of the Initial Digital Prototype, exploring the use of Augmented Reality technology to display the Point of Interest (POI) position, direction, distance, and story chapter order, and guide users to the next location in the story. In the subsequent Paper Prototype, we explored four navigation visualisations, showing the next story element through stylized flags of varying heights. We found that showing the next story location nearer to the bottom of the screen was the most successful way to guide users, but also found that many participants preferred to show location order by distance. In the Narrative Navigation Prototype, further POI design options are explored. We improved details such as size, quantity, description and the spacing of POIs, the camera tilt display, and the use of indicator arrows. In the Final Prototype, the concept of narrative navigation was confirmed by the positive evaluation of participants and confirmation of user interactions provided by our behavioural tracking maps that were used to observe participant movements and prototype interactions.
The thesis contributions include four insights into the concept of narrative navigation. The first is the use of augmented reality to visualise location-based stories on mobile phones; the second is to highlight the importance of showing the next location in the story sequence, which has been almost absent in related work. Removing visited story chapters will facilitate navigation and narrative ordering; and finally, the use of directional indicators that guide the small phone screen to connect to the real world.
We have shown that narrative navigation is a promising concept that can expand application scenarios based on location information.

title: Timing of initiation of reverse displacement on the Taranaki Fault, northern Taranaki Basin: Constraints from the on land record (Oligocene Te Kuiti Group)

authors: Tripathi, Anand Ratnakar Prasad

subjects: Sequence Stratigraphy

abstract: Structures associated with the wedge of basement overthrust into Taranaki Basin along the Taranaki Fault, are regarded as hydrocarbon plays and have been tested by drilling through the tip of the overthrust. The timing of initiation of reverse displace ment on Taranaki Fault is difficult to interpret from available seismic reflection data across it because the evidence has been masked by later movements. The record from the basin, as summarised in King & Thrasher (1996), suggests that the fault evolved from normal to reverse character during the mid-Oligocene. This was inferred from formation of a foredeep parallel to, and west of, Taranaki Fault and a marked increase in its paleo-water depth, as indicated by foraminiferal assemblages of Late Oligocene age.  
A comprehensive re-assessment of the lithostratigraphy and sequence stratigraphy of the Late Eocene-Oligocene Te Kuiti Group exposed on land east of Taranaki Fault in central-western North Island, between Port Waikato and Awakino, provides new constraints on the early history of Taranaki Fault displacement. New age control has been achieved by a review of existing foraminiferal biostratigraphy combined with determination of Sr isotope ages from macrofossil samples. Six unconformity-bound sequences have been identified and mapped within the Te Kuiti Group. A major subaerial unconformity between sequences TK3 and TK4 combined with a basinward shift in the position of onlap for sequence TK4 indicate a dramatic change in stratigraphic development and basin dynamics during the mid-upper Whaingaroan at c. 29 Ma, corresponding to the change from mild extension (sag basin) to shortening across the Taranaki Fault Zone. We consider sequences TK4 – TK6 to each represent tectonic cycles of subsidence and basin inversion and we attribute the origin of these cycles to periodic locking of the Taranaki Fault décollement in underlying Murihiku basement, the accumulating strain causing uplift in the basin east of the fault zone, followed by free displacement, relaxation in the upper crust and subsidence. A 1st order model is presented of the Late Oligocene to earliest Miocene vertical and horizontal displacement of basement on the Taranaki Fault Zone for a west –east transect through Awakino. It implies that the mid- to Late Oligocene displace¬ment on the fault zone in the vicinity of Awakino was episodic, and that the thrust belt was narrow (c. 15 km). North of Kawhia Harbour there will have been a different displacement history with most of the total displacement occurring during the devel opment of the c. 29 Ma unconformity at the base of Sequence TK4, whereas to the south between Awakino and Kawhia Harbour the majority of the total displacement occurred during the Otaian and at the end of it. The model also shows that the start of reverse/thrust displacement on Taranaki Fault must have involved the development of a completely new fault trace(s), rather than involving a change of sense of movement on the pre-existing normal fault. The Manganui Fault is part of the Taranaki Fault Zone and probably became active at c. 27 Ma during development of the unconformity between sequences TK4 & TK5. The model presented here has been validated against the subsurface Oligocene stratigraphy in Taranaki Basin.

title: Repositioning within indigenous discourses of transformation and self-determination

authors: Berryman, Mere

subjects: research-whanau

abstract: This thesis reflectively and critically examines a series of research case studies initiated by a research-whānau. It explores the thinking, experiences and reflections of this research-whānau, as they worked to enhance the educational achievement of Māori students. Authorship of the thesis was undertaken by me (Mere Berryman). However, the methodology involved a collaborative, retrospective and critical reflection of research-whānau experiences and thinking, in the light of the research findings and experiences since the inception of this research-whānau in 1991. In the course of this work, the research-whānau have been able to explore what it has meant to put the principles of kaupapa Māori research into practice while working within a mainstream organisation (Specialist Education Services then the Ministry of Education). Our research work has involved repositioning ourselves from dependence on Western research methodologies to a better understanding and application of kaupapa Māori conceptualisations of research. 
The thesis begins by identifying mainstream and kaupapa Māori events that have historically and still continue to impact upon Māori students' educational experiences. These events provide the wider context for the work of this research-whānau at the interface of Te Ao Māori and Te Ao Pākehā, and for the 11 case studies that exemplify changes in our thinking and research practice over a period of 15 years. The thesis employs an indigenous (and specifically Māori) worldview as the framework for description, critical reflection, and theorising around these case studies. Common themes are collaboratively co-constructed then each theme is explained in relation to relevant Māori theory.
The thesis concludes with the shifts in theorising and practice made by the research-whānau during the course of our work as we sought to contribute in ways that were more transformative and self-determining. We argue that these shifts in theorising and practice are also required of others if we are to change the status quo and contribute constructively to improving Māori students' potential.
