title: Insights on the environmental impacts associated with visible disturbance of ice-free ground in Antarctica

authors: Brooks, Shaun T.

subjects: Science & Technology

abstract: The small ice-free areas of Antarctica provide an essential habitat for most evident terrestrial biodiversity, as well as being disproportionately targeted by human activity. Visual detection of disturbance within these environments has become a useful tool for measuring areas affected by human impact, but questions remain as to what environmental consequences such disturbance actually has. To answer such questions, several factors must be considered, including the climate and biotic and abiotic characteristics. Although a body of research has established the consequences of disturbance at given locations, this paper was conceived in order to assess whether their findings could be generalized as a statement across the Antarctic continent. From a review of 31 studies within the Maritime Antarctic, Continental Antarctic and McMurdo Dry Valleys regions, we found that 83% confirmed impacts in areas of visible disturbance. Disturbance was found to modify the physical environment, consequently reducing habitat suitability as well as directly damaging biota. Visible disturbance was also associated with hydrocarbon and heavy metal contamination and non-native species establishment, reflecting the pressures from human activity in these sites. The results add significance to existing footprint measurements based on visual analysis, should aid on-the-ground appreciation of probable impacts in sites of disturbance and benefit environmental assessment processes.

title: Post-disaster building functionality: Preliminary findings of a systematic review

authors: Boston, Megan

abstract: During a natural hazard event, buildings are likely to experience some sort of damage, thus limiting their ability to function as intended. The severity of the ensuing consequences for various stakeholders and the community depends on the function of the building and the severity of the damage that occurred. A systematic literature review was performed to investigate post-disaster functionality of various building types after a range of natural hazards. Forty-nine documents were deemed to be eligible for inclusion, with most documents discussing healthcare services and businesses due to the vital role they play in short- and long-term community recovery. The functionality of both facility types was found to be dependent on a complex range of structural and non-structural components, as well as social systems, such as staff and the community. The findings of this paper have been used to inform future research directions to apply post-disaster functionality concepts in the New Zealand context.

title: Language switching in a digital library: Does it make a difference if the default language is set to Maori?

authors: Keegan, Te Taka Adrian Gregory

abstract: In this paper we investigate the effect of default interface language on usage patterns of the Niupepa digital library (a collection of historic Māori language newspapers), by switching the default interface language between Māori and English in alternate weeks.
Transaction analysis of the Niupepa collection logs indicates that changing default language affects the length of user
sessions and the number of actions within sessions, and that the English language interface was used most frequently.
