title: An effective, low-cost measure of semantic relatedness obtained from Wikipedia links

authors: Witten, Ian H.

subjects: computer science

abstract: This paper describes a new technique for obtaining measures of semantic relatedness. Like other recent approaches, it uses Wikipedia to provide structured world knowledge about the terms of interest. Out approach is unique in that it does so using the hyperlink structure of Wikipedia rather than its category hierarchy or textual content. Evaluation with manually defined measures of semantic relatedness reveals this to be an effective compromise between the ease of computation of the former approach and the accuracy of the latter.

title: Micro-eukaryotic diversity in hypolithons from Miers Valley, Antarctica

authors: Gokul, Jarishma K.

subjects: Antarctica

abstract: The discovery of extensive and complex hypolithic communities in both cold and hot deserts has raised many questions regarding their ecology, biodiversity and relevance in terms of regional productivity. However, most hypolithic research has focused on the bacterial elements of the community. This study represents the first investigation of micro-eukaryotic communities in all three hypolith types. Here we show that Antarctic hypoliths support extensive populations of novel uncharacterized bryophyta, fungi and protists and suggest that well known producer-decomposer-predator interactions may create the necessary conditions for hypolithic productivity in Antarctic deserts.

title: A case study of Pipiri Ki A Papatūānuku

authors: Tamoko-o-te-rangi, Ormsby

subjects: environmental initiatives

abstract: This thesis is an examination and analysis of the environmental initiative Pipiri Ki A Papatūānuku, co-founded by Waimirirangi Ormsby (née Koopu-Stone) and myself, Tamoko Ormsby. The primary aim of this research was to achieve an understanding of the PKP initiative at the individual level and to inform future collective action at the community level. As such, my primary research question is:

How can Pipiri Ki A Papatūānuku inform community-scale action that contributes to our more-than-human relationship with Papatūānuku within our current capitalist settler-colonial context?

The study is part-autoethnographic in that it is informed by my personal reflections and experiences as a co-founder, operator, and participant of the initiative. In addition, the study explores the number of participants who signed up yearly for each action and employs a brief descriptive analysis of the initiative.

The literature review explores how common Western notions of environmentalism are devoid of the spiritual, cultural, and relational aspects present within indigenous and Māori knowledge systems. It touches on the histories of capitalism and colonialism and how these have led to the consumptogenic society we are in. It aims to illustrate the nexus between the Māori and Western Eurocentric worlds.

He Whatu is the framework that has emerged from this case study as the means to respond to the primary research question. The framework was developed by analyzing the key themes of PKP over the years 2017 to 2021. He Whatu has five key elements: Identity, Language, Distance, Practicality, and Influence; each with three subcategories. It is activated through provoking key conversations to inform future community action.
