title: Revealing the interactional features of learning and teaching moments in outdoor activity

authors: Waters, Jane

subjects: intersubjectivity

abstract: The data considered in this article was generated as part of a doctoral research study entitled: A sociocultural consideration of child-initiated interaction with teachers in indoor and outdoor spaces (Waters 2011) where child-initiated, teacher–child interaction in indoor and outdoor spaces were investigated. The purpose of the secondary analysis was twofold; firstly to explore, more deeply, the establishment of intersubjectivity between teacher and child in educative interaction, particularly in episodes that support and extend thinking. Secondly, the secondary analysis was to consider the role of the environment in such episodes. Through investigating the selected interactions using conversation analysis, it is revealed that children talk their environment into being (Heritage 1978) through the initiation of an interaction using a wh type question. Also, the child's initiation of an interaction regarding the environment sequentially offers the teacher an opportunity to engage in a sustained, affiliated interaction with the child via the mobilized topic.

title: Removal of flatulence causing sugars in soymilk

authors: Rajan, Anila

subjects: Alpha -galactosidase

abstract: The enzyme, alpha-galactosidase was extracted from peanuts using various buffers
and solvents. The specific activity of soluble preparation of peanut ranged from
0.0083 to 0.0606 U/mg. Phosphate buffer extract showed the maximum specific
activity of 0.0606 U/mg. The soluble alpha-galactosidase was immobilised in calcium
alginate beads and the specific activity of the immobilized enzyme was found to
be 0.0808 U/mg. Activity yield was 33%. The immobilised enzyme showed
increase in activity compared with the soluble enzyme above 35 C. The thermal
stability of the immobilised alpha-galactosidase was significantly improved in
comparison to the soluble form. The effect of different pH depicts that at acidic
pH the activity of the immobilised alpha-galactosidase was higher than that of the
soluble enzyme. The Km and Vmax for immobilised enzyme was higher when
compared with the soluble enzyme. Immobilised alpha-galactosidase retained 20%
activity after 7 repeated uses. The immobilised enzyme exhibited high storage
stability. The immobilised enzyme was used in batch and continuous packed bed
reactors for the hydrolysis of stachyose and raffinose in soymilk. Flatulence
causing raffinose and stachyose, after hydrolysis, was removed to a remarkable
extent. Hydrolysis of flatulence causing oligosaccharides of soymilk in a
continuous packed bed reactor has not been attempted previously.

title: Ki te kapu o takau ringa - In the Hollow of my Hand: Wānanga based Photographic Approaches to Place Representation

authors: Hill, Rodrigo

abstract: Ka matakitaki iho au ki te riu o Waikato
 Ano nei hei kapo kau ake maaku; 
Ki te kapu o taku ringa, 
“I look down on the valley of Waikato, 
As though to hold it  
In the hollow of my hand.
 The words above are from Māori King Tawhiao’s maioha (song poem), a representation of his love for his homelands of the Waikato and the region known today as the King Country. Now imagine a large-scale photograph: a close-up of cupped hands, holding an object carefully. The phrase above informs Professor Tom Roa and Dr. Rodrigo Hill’s current research project titled ‘Te Nehenehenui - The Ancient Enduring Beauty in the Great Forest of the King Country’. With this project still in its early stages the research team will present early and ongoing creative practice developments, discussions and ideas about photography practice, wānanga, and place representation. The project promotes the use of wānanga (forums and meetings of focus groups through which knowledge - mātauranga - is discussed and passed on) and other reflective practices, engaging with and led by mana whenua (guardians of the land) providing a thread which will guide the construction of the photographic images. The research fuses wānanga, that is Mātauranga Māori (Māori Knowledge), and photography practice in novel ways, aiming to move away and challenge core photographic conventions and Eurocentric modes of place representation. Roa and Hill understand wānanga as a fluid practice of engagement which can be with mana whenua or with the taiao - the environment - either by itself or with the mana whenua. This is the essence of Kaupapa Māori Research.
