title: Understanding the degree of condensation of phenolic and etherified C-9 Units of in situ lignins

authors: Nanayakkara, Bernadette

subjects: β-aryl ether linkages

abstract: A novel approach for the quantification of the degree of condensation at the C₅ position of etherified and phenolic phenylpropane (C-9) units of in situ lignin is described. This is achieved by degrading unmethylated and methylated wood by thioacidolysis and analyzing the resultant product mixtures by quantitative ³¹P NMR spectroscopy. Applying this new method to compression wood and normal wood from Pinus radiata showed that, whereas 41–47% of etherified guaiacyl C-9 units are condensed at the C₅ position, almost all phenolic guaiacyl C-9 units exist as uncondensed moieties. Analysis of milled wood lignin (MWL) isolated from the same wood by ³¹P NMR spectroscopy before and after thioacidolysis showed that the phenolic guaiacyl C-9 units were more condensed than those in the in situ lignin. This is likely due to partial cleavage of the more condensed etherified linkages during the lignin isolation, leading to a relative increase in condensed phenolic guaiacyl C-9 units.

title: A Sea of Voices: Deep sea mining and the Solwara 1 Project in Papua New Guinea

authors: Phillips, Hayley

subjects: Anthropology

abstract: Deep sea mining is a new and increasingly important part of the capitalist exploitation of the world’s oceans. Situated off the coast of New Ireland Province, Papua New Guinea, Solwara 1 is expected to become the world’s first deep sea mining project. Developments in late 2018, however, suggest that the project might not go ahead. If Solwara 1 does proceed, it shall occur in a country with a long history of mining developments that have produced widespread social and environmental harm. The aim of this thesis is to critically analyse the discursive articulations of four key stakeholder groups: the mining company, the government, local communities and the fourth estate, the latter taken to include NGOs, the scientific community, as well as media. In order to discover how each of these groups portrays and reacts to the Solwara 1 project, this thesis will examine bureaucratic artefacts, such as reports, media releases and social media. It is evident that each party has constructed its own unique discourse regarding the project and its interrelationship with the surrounding communities and marine environment. The mining company claim that local people do not have a tangible or intangible relationship to the sea, which is also echoed by the national government, who are shareholders in Solwara 1. Local communities dispute this however, and argue they are deeply connected to the sea. The fourth estate are primarily concerned with the environmental impacts that deep sea mining may cause. Ultimately, this ‘sea of voices’ presents a situation whereby each stakeholder ultimately constructs a discourse that best serves and advances their own interests, and does so on a highly uneven playing field.

title: Guidelines for gender affirming healthcare for gender diverse and transgender children, young people and adults in Aotearoa New Zealand

authors: Oliphant, Jeannie

abstract: Internationally and within New Zealand there has been a substantial increase in the demand for gender affirming healthcare over the past decade. The Youth’12 secondary school survey, estimated that approximately 1.2% of adolescents in New Zealand identify as transgender.¹ It is likely that this level of referrals to health services will continue in the foreseeable future. 
This guideline has been developed following the recognition that New Zealand’s previous good practice guide, Gender Reassignment Health Services for Trans People within New Zealand,² which was based heavily on the World Professional Association of Transgender Health, Standards of Care, version 6 (WPATH SOC v6),³ requires updating to be in step with current practice and international guidelines.
Transgender healthcare is a rapidly evolving area of medicine. WPATH is the international body responsible for producing standards of care. WPATH SOC v7,⁴ was published soon after New Zealand’s good practice guide and version 8 is currently in development. This guideline is not intended to replace the WPATH SOC but to present additional guidance for the provision of gender affirming healthcare in Aotearoa, New Zealand. We hope that this guide will be used to support the development of health services providing gender affirming healthcare around the country and provide guidance to District Health Boards (DHBs).
We use Sir Mason Durie’s health framework to inform the kaupapa or approach of these guidelines. WPATH SOC v7 encourages culturally appropriate approaches which are contextually based.⁴ Durie’s model for health promotion development, Te Pae Māhutonga (the Southern Cross), has two guiding principles which correspond to the pointer stars of the constellation, Te Mana Whakahaere and Ngā Manukura.⁵
