title: Computer graphics techniques for modeling page turning

authors: Liesaputra, Veronica

subjects: computer graphics models

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; 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 paper 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 that are generated by 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 methods discussed. The simpler techniques support convincing real-time implementations on ordinary workstations.

title: Talking About Race and Positionality in Psychology: Asians as Tangata Tiriti

authors: Tan, Kyle K. H.

subjects: tangata whenua

abstract: The article discusses the dominance of Western, educated, industrialized, rich, and democratic (WEIRD) perspectives in the field of psychology in Aotearoa New Zealand. This has resulted in a racial hierarchy of knowledge, with Indigenous and culturally diverse epistemologies marginalized. The lack of diversity in the curriculum and the limited representation of non-Pākehā (non-New Zealand European) psychologists in the country have led to calls for a more inclusive environment.

The first perspective proposed is to understand Asians as a racialized group with diverse experiences. Asians in Aotearoa come from various backgrounds and face different degrees of racism and acculturation. The notion of 'Asian' may be used to marginalize the interests of Māori, perpetuating institutional racism. The concept of 'Asianisations' describes different forms of racial marginalization experienced by Asians in the country.

The second perspective emphasizes the positionality of Asians as tangata Tiriti (people of the Treaty). Te Tiriti o Waitangi, the Treaty between the British Crown and Māori chiefs, is seen as granting tangata Tiriti equal rights and privileges alongside Pākehā and Māori. As tangata Tiriti, Asians have a responsibility to uphold Tiriti principles, which include partnership, active protection, equity, and options to address Māori inequities. Asian psychologists can engage in culturally safe care for Māori clients and collaborate with and empower Māori leadership in research.

The article highlights the need for Asian psychologists to reflect on their positionality, power structures, and biases within the discipline and society. It encourages them to challenge the dominance of WEIRD psychology and work towards decolonizing the field. By doing so, they can contribute to the flourishing of Kaupapa Māori psychology and develop culturally informed practices that draw on the richness of Asian cultures.
