title: Wiggle-match radiocarbon dating of the Taupo eruption

authors: Hogg, Alan G.

subjects: Taupo eruption

abstract: The Taupo eruption deposit is an isochronous marker bed that spans much of New Zealand’s North Island and pre-dates human arrival. Holdaway et al. (2018, Nature Comms 9, 4110) propose that the current Taupo eruption date is inaccurate and that the eruption occurred “…decades to two centuries…” after the published wiggle-match estimate of 232 ± 10 CE (2 s.d.) derived from a tanekaha (Phyllocladus trichomanoides) tree at the Pureora buried forest site (Hogg et al. 2012, The Holocene 22, 439-449). Holdaway et al. (2018) propose that trees growing at Pureora (and other near-source areas) that were killed and buried by the climactic ignimbrite event were affected by ¹⁴C-depleted (magmatic) CO₂. Holdaway et al.'s (2018) proposal utilises a wide range of published ¹⁴C data, but their work results in assertions that are implausible. Four parts to their hypothesis are considered here.

title: Trust- and location-based recommendations for tourism

authors: Hinze, Annika

subjects: computer science

abstract: Recommender systems in a travel guide suggest touristic sites a user may like. Typically, people are more willing to trust recommendations from people they know. We present a trust-based recommendation service for a mobile tourist guide that uses the notion of directly and indirectly trusted peers. The recommendations combine information about the peers’ ratings on sights, interpersonal trust and geographical constraints. We created two trust propagation models to spread trust information throughout the traveller peer group. Our prototype supports six trust-based, location-aware recommendation algorithms.

title: Supervision as cultural partnership: Contributions to dialogue

authors: Crocket, Kathie

abstract: The term cultural supervision has been coined as part of a strategy that implicates supervision in the support and development of culturally appropriate therapeutic practice. In Aotearoa New Zealand particular focus has been given to supervision where the client is Māori and the practitioner is a member of the dominant Pākehā culture particularly, or of other non-Māori cultures. However, while the phrase cultural supervision has entered common professional parlance, the practice has had little research attention in counselling/psychotherapy in New Zealand. Cultural supervision appears to encompass a range of understandings, and there is no clear agreement about practice implications. It is unclear what alignment there is between aspirations, regulations, and practice. This article reports on an exploratory qualitative study that investigated how supervision might work in supporting culturally appropriate counselling practice in Aotearoa New Zealand. The study’s findings are presented as a multi-voiced dialogue. This arts-based representational practice enacts the uncertainties of post-colonial experience. Its intention is to make assumptions, ideas, and practices available for discussion. Its contribution is to join current dialogue about supervision and culture, and to raise further questions about how supervision and culturally appropriate practice come together.
