title: Text categorization using compression models

authors: Frank, Eibe

abstract: Text categorization, or the assignment of natural language texts to predefined categories based on their content, is of growing importance as the volume of information available on the internet continues to overwhelm us. The use of predefined categories implies a “supervised learning” approach to categorization, where already-classified articles—which effectively define the categories—are used as “training data” to build a model that can be used for classifying new articles that comprise the “test data.” This contrasts with “unsupervised” learning, where there is no training data and clusters of like documents are sought amongst the test articles. With supervised learning, meaningful labels (such as
keyphrases) are attached to the training documents, and appropriate labels can be assigned automatically to test documents depending on which category they fall into.

title: A mosaic of visions, daydreams, and memories: diverse inlays of organizing and communicating from around the globe

authors: Broadfoot, Kirsten J.

subjects: organizing

abstract: This collaboratively multiauthored essay presents diverse tales of organizing and communicative practices in our global context. Authors from India, Nepal, Aotearoa New Zealand, Australia, Brazil, the United States, and Nigeria present individual contributions that coalesce around three clear thematic concerns regarding issues of organizing and communicating: (1) silence and voice, (2) the limits and consequences of linguistic and theoretical translations, and (3) the communal considerations of research politics and participation. The essay concludes with communal reflections on how it is that in attempting to engage with diversity we begin to see remarkable similarities not only in expressing a desire to be heard but also in making a commitment to let others be heard, not only in breaking boundaries and building alliances but also in moving towards a collective, inclusive, and participative conceptualization of the myriad shapes of organizing and communicating that exist in the contemporary global context.

title: Mai i te kore, ki te pō, ki te ao mārama: He kohinga pūrākau hauora o ngā kaumātua Māori, Māori Elders health and wellbeing stories in life transitions

authors: Shelford, Pita

subjects: pūrākau

abstract: Introduction
New Zealand’s general population is ageing. Kaumātua (Māori elders) only make up approximately 3.1 percent of the total population and yet, they are disproportionately overrepresented in poor health, wellbeing and ageing statistics. However, this is a one-sided story and the focus of a deficit approach. There is a strong need for a strength-based approach where kaumātua voices of problem-solving and resilience related to ageing and the changes it presents, are heard. The purpose of this study is to identify and share those voices and to respond to the call from Māori academics to apply pūrākau as an alternative to Western narrative approaches. Through a pūrākau approach, this thesis sought to answer three key research questions: 

1)What are the cultural and communication features of the kaumātua teina narratives?
2) What are the cultural and communication characteristics of the kaumātua tuakana conversational styles? and 
3) What is the nature of the kaumātua journeys in how the stories unfold, and relationships develop? 

Methods
This study analyses pūrākau from the Kaumātua Mana Motuhake (KMM) collaboration project between the University of Waikato and the Rauawaawa Kaumātua Charitable Trust in Hamilton, Aotearoa New Zealand. The KMM project sought to enhance kaumātua wellbeing during life changes such as losses of licence, independence or spouse, health changes and retirement through a peer-support tuakana-teina programme. The KMM team implemented a tuakana-teina peer support programme where kaumātua (n= 121) engaged in up to three conversations as kaumātua tuakana-teina pairs. The conversations involved exploring the life changes the teina chose with the tuakana guiding the conversations and sharing potential services to help with the changes.
This thesis analysed 30 kaumātua conversations in 10 tuakana-teina pairs to tell a strengths-based story of health and wellbeing. Taking a Kaupapa Māori approach, the research prioritised, privileged and foregrounded Māori and Indigenous epistemology, ontology, and axiology. A pūrākau-grounded analysis approach was developed and applied to the conversations.

Findings
Related to the first research question, the analysis revealed kaumātua narratives that spoke to stories about adversity, turning points, independence and resilience. Regarding the second research question, the study identified key cultural and communicational characteristics kaumātua tuakana used, speaking with words of kinship and reciprocation, words of ignition and guidance, and words of empathy and affirmation. Pertaining to the third research question, the analysis illustrated conversational and relational journey types kaumātua pairs travelled, consisting of conversations that went direct to topics, detours that became defining moments, small tiki tours that came back to the topic, stories that were revisited, and hospitality becoming defining moments. 

Conclusions
The findings compiled weave a collective tapestry of kaumātua teina pūrākau, kaumātua tuakana communication styles, and kaumātua conversational and relational journeys. Kaumātua teina have voiced a pūrākau for us to understand inter-generational trauma and how cultural connection liberated their wellbeing. Kaumātua tuakana have composed a script of communication protocols emphasising connection and relationship development essential to upholding tikanga (practices, principles, communications). The paired kaumātua journeys have drawn a signposted road map that highlighted journey types, emphasising reciprocity in conversing, learning, guiding, connecting, developing, strengthening and enhancing communications, relationships, and wellbeing

Implications
Via kaumātua conversations, invaluable understandings into Māori and Indigenous wellbeing, ageing and development scholarship are offered, strengthening transformation, leadership and resilience theories. Pūrākau and whanaungatanga (relationships) methodologies are advocated for and culturally responsive research is promoted. Health, wellbeing and ageing programme development, policy and service delivery can be practically informed, accentuating mentorship, intergenerational initiatives, and culturally appropriate kaumātua support. Together, the findings can cultivate community wellbeing and nurture cultural continuity.
