title: Social media platforms duty of care – Regulating online hate speech

authors: Tan, Rachel Sue Yin

abstract: There has been a proliferation of social media usage over the past decade. Social media platforms offer a convenient mode for virtual social interaction by providing relatively simple access to most people. However, there has been a recurring theme of harassment or bullying by way of hateful speech that causes social harm especially following the Christchurch terrorist attacks in 2019. New Zealand is at a point of inflexion when it comes to updating its laws to combat online hate speech. The manner in which statutory duty of care is proposed as law in other comparative jurisdictions (such as the UK and Australia) will be explored in order to establish whether it is beneficial and necessary to be adopted in New Zealand.

title: Visco–resistive dissipation in transient reconnection driven by the Orszag–Tang vortex

authors: Armstrong, Craig Keith

subjects: Flares

abstract: Viscous effects are expected to significantly contribute to reconnective energy release mechanisms in solar flares. While simple scaling arguments based on head-on reconnection suggest that viscous dissipation may dominate resistive dissipation, it is not clear whether these findings can be applied in more general merging situations. Here we perform side-by-side planar reconnection simulations driven by the Orszag-Tang vortex, for both classical and Braginskii forms of the viscosity. This formulation has the advantage of providing an autonomous MHD system that develops strong current layers, sustained by large-scale vortical shearing flows. The dissipation rates are shown to follow analytically based scaling laws, which suggest that viscous losses generated from large-scale non-uniform velocity fields are likely to dominate resistive losses in current-sheet reconnection solutions.

title: Hapū data sovereignty: Tips for getting started

authors: Clark, Vanessa

abstract: This brief is a part of a series, produced for the Tikanga in Technology (TiNT) research programme, that provides a hapū perspective on data sovereignty, data governance, and data privacy. The purpose is to provide practical advice for individuals, whānau, marae and hapū who are embarking on their own hapū data sovereignty kaupapa, with a particular focus on whakapapa data.
