title: Spatial modelling of wetness for the Antarctic Dry Valleys

authors: Stichbury, Glen

subjects: GIS

abstract: This paper describes a method used to model relative wetness for part of the Antarctic Dry Valleys using Geographic Information Systems (GIS) and remote sensing. The model produces a relative index of liquid water availability using variables that influence the volume and distribution of water. Remote sensing using Moderate Resolution Imaging Spectroradiometer (MODIS) images collected over four years is used to calculate an average index of snow cover and this is combined with other water sources such as glaciers and lakes. This water source model is then used to weight a hydrological flow accumulation model that uses slope derived from Light Detection and Ranging (LIDAR) elevation data. The resulting wetness index is validated using three-dimensional visualization and a comparison with a high-resolution Advanced Land Observing Satellite image that shows drainage channels. This research demonstrates that it is possible to produce a wetness model of Antarctica using data that are becoming widely available.

title: Learning, creative col(labor)ation, and knowledge cultures

authors: Peters, Michael A.

subjects: cybernetic capitalism

abstract: In this conversation, Michael A. Peters analyses the advent of knowl- edge cultures and their relationships to human learning. The first part of the conver- sation analyses social transformation towards the network society and links digital technologies to the making of the society of control. It analyses the dynamics between openness, capitalism, and anti-capitalism, and uses various recent examples to link that dynamics to democracy. The second part of the conversation links cybernetic capitalism to learning and knowledge production, and elaborates the movement of open education. Based on work of Paulo Freire, it develops the notion of openness as an (educational) virtue. It links openness and creativity, introduces Michael Peters’ political economy of academic publishing, analyzes the importance of editing for learning and knowledge production, and briefly introduces the concept of knowledge cultures. The third part of the conversation shows practical applications of these theoretical insights using the examples of two academic journals edited by Michael Peters: Knowledge Cultures (Addleton), and The Video Journal of Education and Pedagogy (Springer). It explores epistemic consequences of peer-to-peer and wisdom- of-the-group approaches, introduces the notions of collective intelligence and col- (labor)ation, and outlines the main features of the new collective imagination. Finally, it shows that doing science is a privilege and a responsibility, and points towards transformation of academic labor from perpetuation of capitalism towards subversion.

title: Waiata anthems: How Aotearoa (New Zealand) popular and contemporary music is addressing generational trauma and revitalising te reo Māori (the Māori language)

authors: Walker, Alroy

abstract: Waiata is translated as song or chant from te reo Māori (the Māori language), yet it has many forms and important functions in te ao Māori (the Māori world). Waiata is most commonly experienced publicly in Aotearoa in support of whaikõrero (oration, formal speech-making), but it also serves to reinforce Māori interconnectedness to others, the natural world and to the supernatural world. Enduring from pre-encounter oral culture, waiata serve as vessels and a mode of transmission for mātauranga Māori (Māori knowledge), histories (whanau, iwi) and culture. This presentation focuses on emergent and contemporary modes of waiata (punk, hardcore and indie) in a post-colonial context, examining musician motivations, the role that music plays in the revitalisation of te reo Māori, and how it honours the purpose of waiata tawhito (traditional waiata). The project is part of ongoing research supported by the partnership agreement between Prifysgol Caerdydd and University of Waikato.
