subjects: science

abstract: Science classrooms in Aotearoa New Zealand may cause some students to feel marginalised.  The inclusion of mātauranga Māori offers a diverse perspective on knowledge which may help inclusion of, and understanding for, these learners.  This research examines how science teachers include mātauranga Māori in their junior secondary science learning activities. 

I am a Pākehā teacher who was born and raised in Hawaii. I have 17 years of science teaching experience in Aotearoa New Zealand. This interpretive, phenomenographic study involved semi-structured interviews with six teachers, all who taught in North Island schools.  Five of the six participants were in schools, and one taught in a Kura Kaupapa Māori.  Data were gathered about teachers’ understanding of te reo Māori, inclusion of mātauranga Māori in the junior secondary science classroom, and how teachers’ own cultural awareness impacted their practice. 

The findings indicate that teachers include mātauranga Māori in their science classrooms in a diverse range of ways. From whole course design to more subtle ways that reflect Māori tikanga and Māori pedagogy.  Teachers often faced challenges in including mātauranga Māori in their science classroom and they overcame these by learning te reo, embracing Māori tikanga and continuing to learn to fill the gaps in their knowledge. The context of the school and its community was also a factor, as well as teachers’ personal philosophies about the nature of knowledge. 

The findings have implications for initial teacher education and professional learning for the integration of mātauranga Māori into the secondary science classroom.

title: Putting it in there: "PSYC575 Indigenous Psychologies" as a for-credit university paper in New Zealand

authors: Waitoki, Waikaremoana

abstract: Over the past 30 years, scholar advocates have sparked the emergence of indigenous psychology as an important contribution to understanding the experiences and challenges faced by indigenous peoples. Part of this exercise is to also bring indigenous knowledges to the learning table as critical information for meaning making and resolving psychological challenges. Increasingly, academics are writing and teaching papers in the fledgling field as important and legitimate contributions for undergraduate and graduate degree credit. Previously, students and academics were confined to the more flexible research driven, directed-learning, study options rather than papers explicitly advertised and institutionally promoted. In this paper, we discuss how we are going about writing the curricula for a graduate level paper called "Indigenous Psychologies" to be offered in 2016 at the University of Waikato, New Zealand. We discuss a) principles that guide curricula decision-making; b) the programme of lecture topics developed; and c) finding and developing supporting resources. We welcome conversation and resource sharing.

title: Chemical aspects of saponin bioactivity and ovine photosensitization diseases

authors: Loader, Jared I.

abstract: A general review of saponin chemistry, bioactivities and of chemical aspects of saponin-associated hepatogenous photosensitization of ruminants (sheep, goats, and cattle) is presented. 
A field trial was undertaken to explore the genin dose/response hypothesis that saponins produced by the plant Narthecium ossifragum may be the direct cause of the toxicity leading to the photosensitization disease alveld seen in Norwegian lambs grazing N. ossifragum containing pastures. The genin content of N. ossifragum leaves from 2 control and 2 outbreak pasture areas, in a region of Norway known for periodic livestock outbreaks of alveld, ranged from 4553 to 10879 mg/kg DM. No significant statistical differences in the mean sapogenin content from the 2 control and 2 outbreak pasture areas were found. Total faecal sapogenin levels determined for lambs grazing the 2 control and 2 outbreak areas ranged from 973 to 36314 mg/kg DM. No obvious relationships between faecal sapogenin levels of lambs exhibiting external alveld symptoms and lambs not exhibiting symptoms were identified. The data does not support the hypothesis that saponins are the sole causative agent for the development of alveld disease symptoms in lambs grazing pastures containing N. ossifragum. 
Genin levels in Scottish collections of N. ossifragum plant material, gathered from pasture on which sheep were photosensitized, were determined. Elevated levels of sarsasapogenin and smilagenin containing saponins were found in flower heads (ca. 18000 mg/kg DM). Significant levels of free genins were found in plant roots (832-1184 mg/kg DM). The percentage contribution (ca. 45-65%) of smilagenin (a 25R-genin) in the Scottish samples was typically 2-4 times greater than is the case for Norwegian collections of N. ossifragum (typically ca. 10-15%). 
A field trial involving the daily intraruminal administration of a 1:4 mixture of [2,2,4,4-2H4]sarsasapogenin and [2,2,4,4-2H4]episarsasapogenin to 4 ewes, their twin lambs, and to 3 weaned lambs over a 21 day period was undertaken in Norway. The results showed that the isotope-dilution methodology can be applied under field conditions to estimate the uptake of sapogenins from plant material under conditions characteristically associated with the development of al veld. 
Mother ewes, on average, consumed 2-3 times the daily weight of N. ossifragum (ca. 700-750 g DM/day) consumed by the lambs (ca. 200-250 g DM/day). Percentage deuterium ratios, determined using SIM GC-MS protocols, while lower that anticipated, were consistent across the animals involved in the trial (between ca. 2-3%). Average N. ossifragum intakes, calculated relative to live-weights, were determined for all sheep involved in the trial. No correlation between the quantity of N. ossifragum consumed and live-weight (g DM day/kg) and the development of alveld was identified. 
The synthesis of sarsasapogenin β-D-galactoside, episarsasapogenin β-D-glucoside, episarsasapogenin β-D-galactoside, betulin 3-(β-D-glucoside) and betulin 3,28-(β-D-diglucoside), was performed via Koenig-Knorr coupling of sarsasapogenin, episarsasapogenin, or betulin with 2,3,4,6-tetra-0-acetyl-α-D-glucopyranosyl bromide, or the corresponding galactoside, followed by hydrolysis of the resulting tetra-0-acetyl-β-Dglycosides.Structures of intermediates, and product glycosides were established using a combination of ES-MS and one- and two-dimensional NMR spectral data. 
The synthesized sarsasapogenin, episarsasapogenin and betulin saponins, 4-methoxyfuran-2(5H)-one 5-(β-D-glucoside), Yucca schidigera 70° Brix extract, a methanol conjugate extract of N. ossifragum leaves and the active triketone fraction (triketone oil) from East Cape Manuka oil were subjected to a bioactivity evaluation against a range of bacterial and fungal organisms using the agar gel well diffusion technique. A possible structure-activity relationship amongst the synthesized saponins is discussed. 
The activity of triketone oil against two fish-pathogenic strains of Saprolegnia parasiticawas evaluated. The evaluation, performed in vitro, required the use of small percentages of water-miscible organic solvents and phosphate buffer solutions to obtain homogenous aqueous solutions. Inhibition of S. parasitica growth was seen at triketone oil concentrations of: (i) 150 and 200 ppm using aqueous solutions containing 0.5% and 1.0% pyrrolidinone, each containing 0.5% Tween 80 and (ii) at 150 and 200 ppm, at both pH 7 .0 and 7.5 of a 0.25 molL-1  phosphate buffer solution. An in vivo toxicity trial found that East Cape triketone oil at 200 ppm was acutely toxic to Atlantic salmon fry, with a 50% mortality rate after a 2 h single dose static bath exposure.
