<p>This study integrates paleonotology and geochemistry to provide a paleoclimatic analysis of cyclic sedimentation in the Lower Marl at Mead Stream in Marlborough, Aotearoa/New Zealand. The alternating marl and limestone bedding in this outcrop coincide with the warmest period in the Paleogene, the Early Eocene Climatic Optimum (EECO).  An acetic acid leaching method was refined and used successfully to extract microfossils from the indurated limestones and marls from two intervals of the Lower Marl. The technique resulted in foraminiferal tests with improved surface ornament in comparison with samples that were processed using standard washing methodology.  The resulting paleontological assessment of leached foraminiferal and radiolarian assemblages coupled with XRF and stable isotope analysis revised the position and detailed the faunal response to the J hyperthermal at the initiation of the EECO. Microfossil assemblages and carbon isotopic data suggest that the J carbon isotopic excursion (CIE) may be a two-stage event. A new L-3 CIE and possible hyperthermal event was identified within the body of the EECO. Both the J and L-3 events contained acmes where Morozovella made up a quarter of the planktic foraminiferal specimens, suggesting the southern expansion of subtropical waters. Fluctuations of Acarinina and Subbotina foraminifera coinciding with the marl and limestone alternations may indicate climate cycles within these hyperthermals.</p>

In this article, we refer to the separation of solid organs from the body as bio-objects. We suggest that the transfer of these bio-objects is connected to emotions and affects that carry a range of different social and cultural meanings specific to the context of Aotearoa New Zealand. The discussion draws on research findings from a series of qualitative indepth interview studies conducted from 2008 to 2013 with Māori (the Indigenous people of Aotearoa New Zealand) and Pākehā (European settler New Zealanders) concerning their views on organ donation and transplantation. Our findings show both differences and similarities between Māori and Pākehā understandings of transplantation. Nevertheless, while many Māori draw on traditional principles, values and beliefs to reflect on their experiences in relation to embodiment, gift-giving, identity and well-being, Pākehā tend to subscribe to more Western understandings of identity in terms of health and well-being, in line with international literature on the topic. Rather than reflecting individualistic notions of the body and transplantation as the endpoint of healthcare as do Pākehā, Māori views are linked to wider conceptions of family, ancestry and belonging, demonstrating how different rationalities and ontologies affect practices and understandings surrounding organ transfer technology. In the article, we focus predominantly on Māori perspectives of organ transfer, contextualising the accounts and experiences of our research participants against the backdrop of a long history of settler colonialism and health inequalities in Aotearoa New Zealand.

The research study focuses on the phenomenon of informal learning and teaching, as it materializes through the quiltmakers’ engagement in idiosyncratic community practices. The present study considers the construction of craft knowledge from a sociocultural perspective, focusing on social and material mediation, and embodiment as a form of meaning-making for quiltmakers. The ethnographic data were collected from two quilting communities in Aotearoa New Zealand and in total 66 quilters volunteered to participate. The fieldwork extended over an eight-month period with data consisting of interviews, observations, fieldnotes and reflective diaries including the visualization of interactive happenings in situ. Chronological content logs were created, and data were analysed by qualitative content analysis. The primary interest was on the verbal (i.e. social), non-verbal (i.e. embodied) and material (inter)actions that were central to the quilters’ meaning-making processes. This praxis and process of informal learning usually make it invisible because it is a ubiquitous element embedded in the quilting community context. Identifying different aspects of multimodal making foregrounds how the quilters’ learning is socially interactive, with ‘hands on’ and ‘minds on’ processes tied to their bodily experiences and material world. This study demonstrates the significance of the ongoing communicative (inter)actions for meaning-making, highlighting the role of the body, mind and environment in shaping quilting practices and appropriating craft knowledge.

<b>This thesis investigates intergenerational collaborative theatre with and for young people in Aotearoa/New Zealand. It researches current practices in theatre for, by, and with young people (henceforth referred to as TYA), in New Zealand, and standards by which quality TYA can be recognised. Utilising an arts research methodology, this thesis identifies practical strategies for engaging a young audience and explores an intergenerational, collaborative devising theatre model for and with young people. It examines how theatre practitioners can work with young people to increase their sense of agency and empowerment in the work. </b><p>The purpose of this research is to contribute to an under-researched body of knowledge within New Zealand theatre, and enhance the current practice and status of TYA in Aotearoa and beyond. It critically analyses the way TYA is created, raising awareness of the body of work in Aotearoa/New Zealand, and contributes to academic and practitioner-based publications about TYA. This investigation aspires to create a pathway for directors and teachers, and to empower practitioners to create great TYA and view it as a valid and valuable career option, not just as a stepping stone to making adult theatre. </p>

<p>This study documents the first detailed palynological analysis of early Eocene strata from the Lower Marl unit at Mead Stream, southern Marlborough, New Zealand. Examination of marine palynomorph assemblages and palynofacies analysis were used to improve biostratigraphic resolution and investigate paleoclimate across the Early Eocene Climatic Optimum (EECO; ~53–49 Ma)—a period characterised by the highest temperatures of the Paleogene. Early Eocene New Zealand dinocyst zones from NZE2–NZE4, and the Charlesdowniea coleothrypta zone are established across the Lower Marl for the first time in this study. Marine palynomorph assemblages originating in outer-neritic conditions and deposited on the upper slope represent low energy transport along the margin of a terrestrial discharge plume. Palynomorph assemblages do not provide insight into sea surface temperature (SST) trends. Palynomorph assemblages may reflect extremely low surface productivity. Cycles in organic matter between marine-dominant limestones to terrestrial-dominant marls, controlled by changes in temperature and seasonal precipitation, may represent orbital forcing by way of precession cycles; however the limited range of high resolution data from this study cannot statistically confirm this. An overall increase of allochthonous organic matter across the Lower Marl is likely representative of long-term background warming, culminating in peak EECO temperatures. The base of a hyperthermal, represented by carbon isotope excursion (CIE) previously identified at Mead Stream has been redefined in this study. High abundances of warm water, extreme salinity taxa coincide with the onset of this warming event.</p>

In this chapter, the author discusses the significance of the body as part of its natural environment, with particular emphasis on sensuous interfaces and somatic presence of the body as nature. The author, a dancer, educator, and ecologist, explores somatic presence in and as nature as she recounts some of her own somatic memories of place. More specifically, she traces her somatic memory of living, dancing, and teaching in Aotearoa, New Zealand. In the process she describes her ecological body as an expressive aspect of nature, as well as the ways that time spent in the natural environment has influenced her choreographic expression and danced improvisations within natural and constructed landscapes of earth and stage. Her emphasis is on the unification of self and world she experiences through dance performance.
