title: Lexical attraction for text compression

authors: Bach, Joscha

subjects: computer science

abstract: New methods of acquiring structural information in text documents may support better compression by identifying an appropriate prediction context for each symbol. The method of “lexical attraction” infers syntactic dependency structures from statistical analysis of large corpora. We describe the generation of a lexical attraction model, discuss its application to text compression, and explore its potential to outperform fixed-context models such as word-level PPM. Perhaps the most exciting aspect of this work is the prospect of using compression as a metric for structure discovery in text.

title: Meanings of 'the Outdoors': Shaping outdoor education in Aotearoa New Zealand

authors: Straker, Jo

subjects: Outdoor Education

abstract: Abstract
The issue of human-nature relationships has become increasingly important given the environmental issues affecting the world. Thus, education which can encourage students to positively engage and connect with the world around them is vital. Outdoor education offers one way to help build relationships, but only if outdoor educators have an understanding and appreciation of the ways 'the outdoors' influences their pedagogy. Over the years, growing emphasis on adventure activities, social and personal development, and experiential learning styles, has subsumed the role of 'the outdoors' within outdoor education.
Using an interpretive narrative framework, this research focuses on 'the outdoors' as a defining feature of outdoor education.  A series of three semi-structured interviews with 11 outdoor educators provided opportunities to explore meanings of the outdoors and how those meanings influenced their understandings and practices of outdoor education. An inductive analysis of the interviews identified five primary themes; locations, activities, living simply, emotional responses, and relationships, and these were used to unpack the participants' beliefs and experiences of 'the outdoors' and outdoor education. In order to retain the richness and complexity of the meanings the participants shared, the findings are presented in a variety of formats including vignettes and poetic text. 
The findings are multi-layered, something that reflected the dynamic nature of 'the outdoors' and the ensuing opportunities offered for creative and critical thinking. There was also evidence that the participants were vigilant about adopting a multi-dimensional approach to outdoor education. This required integrating pragmatic pro-environmental actions, experiential opportunities, challenge activities, spontaneous learning moments, and quiet time into many of their sessions. In so doing, they ensured experiences for their students were holistic, meaningful, and engaging, as well as promoting a respectful relationship with 'the outdoors'. Some of these practices were constrained at times by the expectations of current secondary school educational orthodoxies, especially those relating to assessing pre-determined outcomes. Nonetheless, there was an unreserved belief that outdoor education has an increasingly distinct and important role to play in the school curriculum. How this will be enacted depends on the challenges and opportunities that rise and fall with changing social, political, and economic agendas.

title: Relational Responsive Pedagogy, Teachers and Māori students Listening and Learning from each other

authors: Joyce, Chrisandra Itirana

subjects: Relational Pedagogy

abstract: This thesis examines the culturally responsive and relational pedagogical practices of a group of teachers in one Phase four Te Kotahitanga school. It then considers the influences of these pedagogies on four Māori students.
The thesis begins by seeking to understand the two different worldviews in Aotearoa/New Zealand (a Western worldview and a Māori worldview) and some of the discourses that have emerged in the shared Māori and colonial history of this country. It examines kaupapa Māori as both a movement of resistance to the dominant Western worldview that came with colonisation; and a movement of revitalisation to Māori ways of knowing and understanding the world that began to be lost at the same time. It focuses on Te Kotahitanga as a kaupapa Māori response in secondary schools.
The collaborative storying of teachers and Māori students in a Te Kotahitanga school alongside their data of practice and achievement are discussed and examined. Shifts across three levels of the school are identified and understood alongside the Te Kotahitanga professional development cycle. These understandings are discussed in relation to Māori metaphors.  The overall implications of Māori metaphors in relation to the research questions are then considered.
This thesis concludes with considerations and implications for others in addressing the on-going educational disparities of Māori students in mainstream educational settings in New Zealand.
