title: Quaternary warping at Gorge Saddle, western Southland

authors: Force, Eric R.

abstract: Gorge Saddle is one low point on a drainage divide between Fiordland and the Southland Plain. Eastward sloping Quaternary terraces east of the divide and westward sloping terraces to the west contain granitic pebbles which could have been derived only from the west. This suggests doming at the present divide concurrent with transport from the west.

title: Measuring Auditory Thresholds in Brushtail Possums (Trichosurus Vulpecula)

authors: Osugi, Mizuho

subjects: Audiogram

abstract: A total of 9 brushtail possums (Trichosurus vulpecula) were trained to perform a two-manipulanda, conditional discrimination task.  The possums learned to press a right lever in the presence of a tone (80 dB(A)) during tone-on trials, and a left lever in the absence of the tone on tone-off trials.  Overall sessions of 11 conditions contained tone frequency between 100 Hz and 35 kHz were tested.  Each condition contained training and then probe sessions.   In training sessions, the possums were presented with tone-on and tone-off trials, pseudo-randomly.  Once the possums responded with over 90% accuracy for five consecutive sessions, then probe sessions were introduced.  Probe sessions were similar to the training sessions, except that the tone intensity for tone-on trials was reduced by 8 dB(A) across blocks of 20 trials until their response accuracy in a block fall below 60% or reached 24 dB(A).  Data were analysed using overall percentages correct and log d analysis.  Both measures indicated that overall response accuracy decreased for all possum as tone intensity reduced.  Based on these data analyses, threshold values were calculated using the criterions at 75% correct and a log d of 0.48.  The threshold values for each possum and across all possums were plotted as a function of the tone frequency to produce an audiogram.  A curvilinear regression was fitted for each threshold values.  The functions of both measures were very similar.  Both audiograms showed that the possums could hear the tones between 100 Hz and 35 kHz, and were most sensitive to tones between 15 and 20 kHz.  This experiment involved many difficulties with producing and measuring tones especially outside of human hearing range.  Due to these difficulties, several problems and concerns were raised during the experiment, these were discussed in this study and also recommendations for future research were then presented.

title: Taku Ara, Taku Mahara: Pākehā Family Experiences of Kaupapa Māori and Bilingual Education

authors: Barnes, Alexander Louis

subjects: Kaupapa Maori

abstract: Kaupapa Māori (indigenous Māori-centred philosophies) initiatives have transformed various social, cultural and public projects in the domains of governance and constitutional issues, health, education, the environment, community development and research in Aotearoa – New Zealand. As a Pākehā graduate of te kōhanga reo and kura kaupapa Māori (Māori language immersion pre-school and primary school), this research is concerned with exploring the impact of kaupapa Māori and bilingual educational initiatives on my life and the lives of two other Pākehā families who share similar educational backgrounds. This foundational study utilises qualitative narrative inquiry methods as a means of understanding and analysing the implications for Pākehā as a result of their participation in kaupapa Māori and bilingual education. An intergenerational family approach is used in this research whereby the individual voices and experiences of young adults are heard equally alongside their parents’. Collectively understood, the themes represented in this research offer a unique means of understanding why Päkehä families decided to be involved in Māori immersion settings, and what these experiences mean to them now. One of the principle aims of this study is that it be used as a platform for dialogue amongst Pākehā, non-Māori and Māori about the future direction of bicultural education in Aotearoa – New Zealand.
