title: Cenozoic temperate and sub-tropical carbonate sedimentation on an oceanic volcano – Chatham Islands, New Zealand

authors: James, Noel P.

subjects: Bryozoans

abstract: The Chatham Islands, at the eastern end of the Chatham Rise in the South-west Pacific, are the emergent part of a Late Cretaceous to Cenozoic stratovolcano complex that is variably covered with limestones and fossiliferous tuffs. Most of these deposits accumulated in relatively shallow, high-energy, tide-influenced palaeoenvironments with deposition punctuated by periods of deeper-water pelagic accumulation. Carbonate components in these neritic deposits are biogenic and dominated by molluscs and bryozoans – a heterozoan assemblage. The widespread Middle to Late Eocene Matanginui Limestone contains local photozoan elements such as large benthonic foraminifera (especially Asterocyclina) and calcareous green algae, reflecting the general Palaeogene sub-tropical oceanographic setting. More localized Late Eocene to Oligocene deposits (Te One Limestone) as well as Pliocene carbonates (Onoua Limestone) are, however, wholly heterozoan and confirm a generally cooler-water oceanographic setting, similar to today. Early sea floor diagenesis is interpreted to have removed most aragonite components (infaunal bivalves and epifaunal gastropods). Lack of aragonite resulted in the absence of intergranular calcite cementation during subaerial exposure, such that most carbonates are friable or unlithified. Cementation is, however, present at nodular hardground–firmground caps to metre-scale cycles. Such cements are microcrystalline or micrometre-thick isopachous circumgranular rinds with insufficient definitive attributes to pinpoint their environment of formation. The overall palaeoenvironment of deposition is interpreted as mesotrophic, resulting in part from upwelling about the Chatham volcanic massif and in part from nutrient element delivery from the adjacent volcanic terrane and coeval volcanism. Biotic diversity in tuffs is two to three times that in limestones, supporting the notion of especially high nutrient availability during periods of volcanism. These mid-latitude deposits are strikingly different from their low-latitude, tropical, photozoan counterparts in the volcanic island–coral reef ecosystem. Ground water seepage and fluvial runoff attenuate coral growth and promote microbial carbonate precipitation in these warm-water settings. In contrast, nutrients from the same sources feed the system in the Chatham Islands cool-water setting, promoting active heterozoan carbonate sedimentation.

title: Mindfulness-based stress reduction in a correctional facility: A systematic literature review and meta-analysis on the impact of violent behaviour

authors: Edward, Mtakwa

subjects: MBSR

abstract: Criminal behaviours can often lead to a prison sentence, and a prison sentence suggests that justice has been served. It appears that correctional facilities worldwide have been inundated with prisoners serving time for a variety of reasons.  Though a prison sentence serves as punishment for perpetrators, it can often cause psychological harm for both prisoners and their families. As a result of more relevant research being conducted, several intensive rehabilitative programmes are being run in correctional facilities worldwide to address criminal behaviours such as violence. These intensive programmes aim to teach prisoners to understand the relationships between intrusive thought patterns that may or may not be associated with past traumatic events, emotional dysregulation, and poor behaviour leading to violent offending.  The present study examined the impact of Mindfulness-Based Stress Reduction (MBSR) on prisoners' psychological wellbeing in correctional facilities worldwide. It was completed by running a meta-analysis on four studies based in the United States of America (USA), China, and the Netherlands and across various ethnic and cultural groups, which analysed this relationship. The results indicated that MBSR could be an effective treatment modality to run alongside intensive therapies.
Furthermore, the overall effect size suggested a positive but not significant relationship between MBSR and improved psychological wellbeing. It is suggested that further research using experimental designs be explored in this field to allow for further analysis to be examined. The main objective of this review was to answer two questions: 'Is the use of MBSR in correctional facilities effective in helping reduce recidivism rates?' and 'Will the use of MBSR be effective with different cultural and ethnical populations in correctional facilities?' The conclusion of the meta-analysis in the current study suggests that yes, it is possible to reduce recidivism rates through using MBSR as an effective treatment in correctional facilities. Furthermore, it can be successfully implemented across people of different cultures and ethnicities.

title: The contested shift to a bicultural understanding of place heritage in Aotearoa New Zealand

authors: Passey, Emma

abstract: This article explores contemporary threads in the heritage history of Aotearoa New Zealand, as we witness in real-time the emergence of alternative narratives of Indigenous heritage, in contrast to those of Western dominated modernity and colonial hegemony. Moves to actively decolonise heritage studies is creating shifts in the bicultural understanding of culture and heritage to overtly include place heritage. As this new framing emerges, wider acknowledgement of the significance of Māori heritage landscapes is growing. This is explored here in a series of four case-studies. Each account illustrates how Indigenous Māori voices have gained momentum, and reinforces how Aotearoa New Zealand is transitioning to greater bicultural appreciation through inclusion, changes in social and cultural conventions, and new interpretations of dominant narratives using tools like critical heritage studies and existing legal conventions. This evolution of heritage values is not without repeated contestation, however. Positively, increasing numbers of settler-Pākehā (non-Māori) as well as those colonised, no longer believe or accept the histories previously told. Much needed, robust, and sometimes difficult discussions are taking place, enabling New Zealanders to reconsider the significance of what heritage means to all its people.
