title: Evidence of plant and animal communities at exposed and subglacial (cave) geothermal sites in Antarctica

authors: Fraser, Ceridwen I.

subjects: Science & Technology

abstract: Geothermal areas, such as volcanoes, might have acted as glacial microrefugia for a wide range of species. The heavily glaciated but volcanically active Antarctic continent presents an ideal system for assessing this hypothesis. Ice-free terrain around volcanoes in Antarctica is, however, often restricted to small patches, whereas subglacial cave systems, formed by vented volcanic steam, can be extensive and interconnected. No observations of macrobiota have yet been made for subglacial geothermal environments in Antarctica, but these organisms are often patchily distributed and can be difficult to find. We carried out metabarcoding (eDNA) analyses of soil samples taken from exposed areas on three volcanoes in Victoria Land, and subglacial caves on Mount Erebus. We found evidence of numerous eukaryotic groups, including mosses, algae, arthropods, oligochaetes and nematodes, at both exposed and subglacial sites. Our findings support the notion that geothermal areas—including subglacial environments—can nurture biodiversity in glaciated regions.

title: Social inclusion through ageing-in-place with care?

authors: Barrett, Patrick

subjects: ageing-in-place

abstract: The onset of ill-health and frailty in later life, within the context of the policy of ageing-in-place, is increasingly being responded to through the provision of home care. In the philosophy of ageing-in-place, the home provides for continuity of living environment, maintenance of independence in the community and social inclusion. The provision of assistance to remain at home assumes continuity in the living environment and independence in the organisation of daily life and social contact. This paper explores the changes that occur as a result of becoming a care recipient within the home and concludes that the transition into receiving care is characterised by discontinuity and upheaval which tends to reinforce social exclusion. We draw on the rites of passage framework, which highlights social processes of separation, liminality and reconnection, in analysing this transition to enhance understanding of the experience and gain insights to improve the policy and practice of home care. Separation from independent living leads to a state of liminality. The final stage in the rites of passage framework draws attention to reconnections, but reconnection is not inevitable. Reconnection is, however, an appropriate goal for the care sector when supporting frail or disabled older people through the transition into becoming a home-care recipient.

title: From assimilation to biculturalism: Changing patterns in Maori-Pakeha relationships

authors: Thomas, David R.

subjects: New Zealand

abstract: This chapter examines the changing patterns of inter-ethnic relationships among Maori and Pakeha in New Zealand, specifically the moves from assimilation towards biculturalism. The impact of recent debate about the Treaty of Waitangi is described and examples of bicultural policies and their consequences are outlined.
