title: The Significance of subsurface water as a geomorphic agent in an area of the Greywacke Ranges near Whitehall

authors: Oliver, Timothy Ian

abstract: The area chosen for study is situated in the Whitehall district approximately 7 ½ miles ENE of Cambridge at GR N66/106378 (Figure 1). Recent mass movement features on part of the south and southeast-facing slopes of a valley that is tributary to the Karapiro Stream, and thence the Waikato River, were studied in some detail, but reference is also made to specific features in the area draining to the east. The southwest-facing slopes, with a relative relief of nearly 500 feet, rise to about 1,200 feet a.s.1., where a plateau-like surface dissected by broad mass movement gullies, slopes gradually to the east.

title: Computer graphics techniques for modeling page turning

authors: Liesaputra, Veronica

subjects: computer science

abstract: Turning the page is a mechanical part of the cognitive act of reading that we do literally unthinkingly. Interest in realistic book models for digital libraries and other online documents is growing. Yet, actually producing a computer graphics implementation for modeling page turning is a challenging undertaking. There are many possible foundations: two-dimensional models that use reflection and rotation; geometrical models using cylinders or cones; mass-spring models that simulate the mechanical properties of paper at varying degrees of fidelity; and finite-element models that directly compute the actual forces within a piece of paper. Even the simplest methods are not trivial, and the more sophisticated ones involve detailed physical and mathematical models. The variety, intricacy, and complexity of possible ways of simulating this fundamental act of reading is virtually unknown. This article surveys computer graphics models for page turning. It combines a tutorial introduction that covers the range of possibilities and complexities with a mathematical synopsis of each model in sufficient detail to serve as a basis for implementation. Illustrations are included, which are generated through our implementations of each model. The techniques presented include geometric methods (both two- and three-dimensional), mass-spring models with varying degrees of accuracy and complexity, and finite element models. We include a detailed comparison of experimentally determined computation time and subjective visual fidelity for all the methods discussed. The simpler techniques support convincing real-time implementations on ordinary workstations. We also address the question of whether such techniques are worthwhile in practice by describing results from a user study that compared the performance of a page turning book model with HTML and PDF presentations of the same material—and with physical books. This demonstrates that the book model has many advantages over conventional document formats.

title: Kia mau ki te aka matua: Researching Māori development and learning

authors: Hohepa, Margie Kahukura

abstract: The article involves a search for what might be useful, relevant and appropriate research framework for Māori for the study of Māori development and learning. It is also an attempt to articulate psychological approaches that will validate indigenous cultural epistemologies that support indigenous movements towards self-determination and that also provide useful tools for examining development and learning.
