title: Doctorates in the dark: Threshold concepts and the improvement of doctoral supervision

authors: Johnson, E. Marcia

subjects: threshold concepts

abstract: The overall goal of this qualitative research case study into doctoral writing was to determine if there were knowable threshold concepts and, if so, to develop effective strategies for helping students overcome them. In addition, it was understood that such strategies could have change implications for supervisory practice. Interview and survey data were collected from students and supervisors. From the student data two threshold concepts had emerged: “Talking to think”—a strategy for developing clarity in writing; and self-efficacy—the belief in one's ability to overcome writing barriers and become an independent academic researcher. In this paper, those two threshold concepts provide an organising framework for the presentation of supervisor findings and for discussion of supervisor professional development needs. The paper concludes with insights into how supervisor professional development could be improved and extended beyond its current focus on regulations and compliance issues.

title: Proof-of-learning: A blockchain consensus mechanism based on machine learning competitions

authors: Bravo-Marquez, Felipe

abstract: This article presents WekaCoin, a peer-to-peer cryptocurrency based on a new distributed consensus protocol called Proof-of-Learning. Proof-of-learning achieves distributed consensus by ranking machine learning systems for a given task. The aim of this protocol is to alleviate the computational waste involved in hashing-based puzzles and to create a public distributed and verifiable database of state-of-the-art machine learning models and experiments.

title: How is the circular economy emerging in Aotearoa New Zealand? Research Brief

authors: Diprose, G

abstract: The results of the environmental scan show that there is grass-roots activity and that we have some high level conceptualisations of circular economies (CE) however there is little in-between. As such, it is in the middle that activity needs to occur to transition towards a circular economy. We see a need to move beyond business-as-usual with an entity focus to an ‘ecosystem phase.’ This means that for CE, partnerships are needed across business, organisations, Treaty partners, institutions, NGOs and stakeholders to form collaborations around material and people flows in order for ecosystems to form and create circular economies.
