title: Antarctic Treaty system: achievements and prospects

authors: Daya-Winterbottom, Trevor

subjects: Antarctica

abstract: The Antarctic Treaty 1959 has now been in place for 60 years and is regarded by informed commentators as one of the most successful multi-party international treaty systems. This paper provides an opportunity to look back and take stock of previous success, and more importantly, an opportunity to assess the future prospects of the treaty system.
New Zealand has played a key role in the Antarctic Treaty system and has had a long involvement with Antarctica since accepting the transfer of sovereignty over the Ross Dependency in 1923. This paper therefore focuses on the effectiveness of the Antarctic Treaty system through a New Zealand lens.

title: Using absolute metric maps to close cycles in a topological map

authors: Jefferies, Margaret E.

subjects: cognitive mapping

abstract: In simultaneous localisation and mapping (SLAM) the correspondence problem, specifically detecting cycles, is one of the most difficult challenges for an autonomous mobile robot. In this paper we show how significant cycles in a topological map can be identified with a companion absolute global metric map. A tight coupling of the basic unit of representation in the two maps is the key to the method. Each local space visited is represented, with its own frame of reference, as a node in the topological map. In the global absolute metric map these local space representations from the topological map are described within a single global frame of reference. The method exploits the overlap which occurs when duplicate representations are computed from different vantage points for the same local space. The representations need not be exactly aligned and can thus tolerate a limited amount of accumulated error. We show how false positive overlaps which are the result of a misaligned map, can be discounted.

title: Network Analysis Reveals Unique Associations of Mindfulness and Distress with Immunity in Māori and Non-Māori New Zealanders

authors: Billot, Moana

abstract: Objectives: 
A healthy immune system is required to protect against viral infection and ensure the efficacy of vaccines. Psychological distress can threaten immune resilience, while mindfulness practices can be protective. In New Zealand, Māori experience significantly higher levels of distress compared to non-Māori. The aim of this study was to explore the role of ethnicity in the relations among immunity, depression, anxiety, stress, and mindfulness relate to each other.
Method:
Network analysis was used to explore unique relations among distress (depression, anxiety, stress), mindfulness facets, and immune status in matched (age, ranging from 19 to 88 years, sex, and self-classified socio-economic status) samples of Māori (n=195) and non-Māori (n=195) participants from New Zealand.
Results:
The networks of distress, mindfulness, and immune status were significantly different between Māori and non-Māori participants. The mindfulness facets Describe and Act with Awareness were more strongly positively linked in Māori, and Non-judge and Depression more strongly negatively linked in Māori, while Describe and Non-judge were more strongly positively linked in non-Māori. For both Māori and non-Māori, similarities included a negative link between anxiety and immune status, strong positive links between the distress variables, and positive links between the mindfulness facets of Non-judge and Act with Awareness, Observe and Non-React, and Observe and Describe.
Conclusions:
These findings suggest that anxiety is strongly linked to poor immunity across both Māori and non-Māori in New Zealand while networks of mindfulness and distress also demonstrated differences unique for each of these groups. Both similarities and differences between Māori and non-Māori should be considered when developing targeted interventions to improve physical and mental health in New Zealand.
