title: Sulfide-bridged aggregates from the metalloligand [Pt₂(μ-S)₂(PPh₃)₄] and β-diketonate complexes of cobalt(II) and zinc(II)

authors: Bridson, James Hadley

subjects: Zinc complexes

abstract: Reaction of [Pt₂(μ-S)₂(PPh₃)₄] with a range of zinc(II) and cobalt(II) complexes ML₂, where L is a β-diketonate ligand CH₃COCHCOCH₃, PhCOCHCOPh, CF₃COCHCOTh (Th = 2-thienyl)] permits the synthesis of adducts [Pt₂(μ-S)₂(PPh₃)₄M(diketonate)]⁺, isolated as their BPH₄⁻salts in moderate yields. The cobalt and zinc acetylacetonate complexes were characterised by single-crystal X-ray diffraction studies, which reveal isomorphous structures, with tetrahedral heterometal centres.

title: The Prevalence and Targets of Cyberbullying Behaviours: An Observational Approach

authors: Hodge, Emma-Leigh

abstract: The online environment has few boundaries and is evolving quickly, which may enable a greater prevalence of negative behaviour, like cyberbullying. Most cyberbullying researchers have used self-report methodologies, focussed on young people, and have had limited ability to explore contextual factors such as whether messages were retaliatory. Using stratified sampling, we selected a total of 40 YouTube® clips showing singing or dancing performances by young girls and boys. We conducted an exploratory content analysis using the first 20 comments for each of these clips (n = 800), coding eight quantitative factors and identifying themes for each comment. The key measure was the degree of positivity of each comment towards the performer in the clip, and if applicable, the degree of positivity towards the other commenters. Negative comments were directed at performers in 20% of the observed cases, whereas 74% of the comments directed at other commenters were negative, suggesting that commenters are most at risk of receiving negative comments online. Male performers received more negative comments than female. About a third of commenters appeared to criticise users for posting negative comments towards others, which is of continued interest because bystander intervention may mitigate some of the harmful effects of cyberbullying.

title: Te Kahautu Maxwell on Te Kooti and Ringatu (Interviewed by Tama Muru)

authors: Maxwell, Te Kahautu

abstract: In October 1869 musket fire erupted at Te Porere about sixty kilometres north of here, in the shadow of Mount Tongariro in the last major battle of the New Zealand wars. 

Armed constabulary and Maori fighters, clashed with the forces of the prophet Te Kooti Arikinui Te Turiki who had built an earth redoubt at Te Porere.  It was overwhelmed during the battle, but Te Kooti and his surviving followers escaped. 

Today the site is a tourist attraction but what also endured is the Ringatu Church, founded by Te Kooti. In 2018 it celebrated its 150th anniversary. 

Ringatu mixes the Bible with Maori custom and, like Matariki, follows annual cycles such as Te Huamata in June for planting and Te Pure, the harvest, each November. 

We spoke to Professor Te Kahautu Maxwell , a minister in the Ringatu Church and a senior academic in Maori and Indigenous Studies at the University of Waikato.
