title: Anthropogenic impacts on the Glowworm Cave, Waitomo, New Zealand: a microclimate management approach

authors: Hendy, Chris H.

subjects: cave microclimate

abstract: Waitomo Glowworm Cave is a highly visited cave where the highlight is viewing the bioluminescence display of a large colony of glowworms. The visitation levels result in the build-up of anthropogenic CO₂, to the extent that it could cause corrosion of speleothems. The cave experiences chimney-effect ventilation with air flowing either upward or downward through the main cave chambers depending on air density differences between the cave and the outside environment. Lack of airflow leads to CO₂ build-up; however, unrestricted airflow can draw in cool, dry air which is harmful to the glowworms. Consequently, airflow is managed by controlling the opening and closing of a door that seals the upper-most entrance, preventing ventilation under drying conditions and promoting ventilation when it is necessary to clear CO₂ and when inflowing air has high relative humidity. A network of microclimate sensors in the cave allows prediction and management of the ventilation pattern. Management leads to asymmetric airflow through the year, which has a flow-on effect on cave temperature. Microclimate monitoring supports the current management practices that use door control to enhance cave ventilation when people are in the cave. Suppressing airflow, especially in winter, reduces the introduction of dry air.

title: Towards the design of a kid’s music organizer

authors: Cunningham, Sally Jo

subjects: computer science

abstract: In this paper, we investigate how young children aged 2 to 5 interact with music and their family's music collections. By going into their homes, interviewing them and their parents and observing the children performing a range of music-related tasks, we explore the way that pre-school children select, interact with, and organize music. Additionally, drawing tasks were included in the visits to engage the children and allow them to demonstrate their thoughts in a concrete manner. Insights into the children's' music behaviours suggest design features for a music organizer / player for very young children.

title: Whanaungatanga: an illustration of the importance of cultural context

authors: McNatty, William

subjects: Te reo Māori

abstract: The word 'whanaungatanga' is often used by people who lack an intimate understanding of the philosophical base in Māori culture out of which it emerges. Thus, it is sometimes used simply to describe the camaraderie that can be associated with team sports or with reference to the 'glue' that connects people to one another socially. This is not necessarily a problem in itself. After all, change and development in the lexicon is a characteristic of living languages. However, real problems can emerge where words become divorced from their cultural roots to such an extent that two speakers using the same word can completely fail to understand one another. It is argued here that this is what can happen when Māori words, such as 'whanaungatanga', are used in the context of modelling in the social sciences, particularly where that modelling is conducted in the context of Western social and cultural values. In particular, the essential spiritual dimension of whanaungatanga may be overlooked or misunderstood.
