title: Late Quaternary tephras in the Hamilton Basin, North Island, New Zealand

authors: Lowe, David J.

abstract: This paper summarises the occurrence and distribution of late Quaternary tephras in the Hamilton (Middle Waikato) Basin and outlines a model to explain the pattern of soils formed from them. The collaborative work currently in progress on paleoecological aspects of the late Otiran - Aranuian history of the area is also reported.

title: Impact of environmental education on beginning preservice teachers’ environmental literacy

authors: Dada, Deborah O.

abstract: One of the goals of environmental education is the development of environ- mental literacy. The development of environmental literacy for preservice teachers is critical if they are to be con dent and competent to deliver envi- ronmental education in schools. Little is known about the impact of envi- ronmental education on preservice teachers’ environmental literacy and their subsequent practices as teachers within schools in New Zealand. This study used a mixed-methods approach with a pretest and posttest design to examine the environmental literacy of preservice teachers enrolled in a compulsory environmental education paper as part of their Bachelor of Teaching program at a New Zealand university. The perceptions of the pre- service teachers’ preparedness to teach environmental education was also examined. Findings indicate that despite only slight shifts in preservice teachers’ environmental literacy, their con dence to teach environmental education signi cantly increased after completing the paper. Increases in the strength of correlations between environmental knowledge and affec- tive dispositions were observed upon completing the environmental edu- cation paper. Implications of ndings for teacher education programs are discussed. This study could inform curriculum design and teaching and learning practices for effectively preparing preservice teachers to promote the development of the environmental literacy of students in their future schools.

title: Studies on the conservation of waterlogged wood in New Zealand

authors: Wallace, Roderick Thomas

abstract: This thesis is a study of properties of certain New Zealand woods recovered from waterlogged environments. The woods are those which were commonly used by the pre-european Maori to make artefacts, and the properties are those which affect the way these artefacts can be conserved after they have been removed from wet archaeological sites.
The properties studied were (a) the species of wood used (b) the forms and shapes of the timbers (c) the densities (d) directional shrinkages, and (e) directional penetrabilities of each wood. The results of this research are intended to aid conservators to correctly treat the artefacts. 
The research began with studies of (a) New Zealand wet site archaeology, (b) the structure and properties of wood in general, and (c) the techniques used to conserve waterlogged wood worldwide.
This was followed by a survey of circa. 1000 wooden Maori artefacts from Museums involving the identification, by thin section microscopy, of wood species. 30 wood types from 22 tree species were found to have been widely used. A collection was made of samples of each type in different states of decay. 
Each sample was tested for density, directional shrinkage and directional penetrability.
The penetrability was measured by vacuum impregnation of water into wood blocks. Results were compared to those from sound oak (Quercus robur), a wood which has been studied intensively by conservators in Europe. 
Detailed summaries of the conservation properties of 26 wood types are given. This reveals that while some New Zealand woods are easy to conserve others provide considerable problems. The latter woods are all highly durable in wet sites, extremely dense, have high shrinkages and are highly impenetrable. These will require special types of treatment to avoid damage during conservation.
