title: Tertiary teaching: Reflecting on human change and influence from the crucible

authors: Kelly, Janette

abstract: This article draws on the metaphor of ‘a crucible’ to describe the tertiary classroom context, where I work in initial teacher education with early childhood education (ECE) student teachers. Stories are told about the classroom participants (students and an educator) in an attempt to find meaning in terms of development, both the students and mine. This storytelling highlights ongoing questions for me about the impact of what happens in the classroom we bring our selves to, and the significance of informed actions for social justice for teachers and teaching. In telling these stories I highlight my deepening understanding of education pedagogy, and perception of myself as a teacher, a practitioner of human influence and change. I hope that these stories echo and illuminate the experiences of other educators as they too seek to understand their practice.

title: Total site utility systems optimisation for milk powder production

authors: Walmsley, Timothy Gordon

abstract: This study applies the Total Site Heat Integration method, in conjunction with a detailed process and utility model, to investigate three methods to increase the energy efficiency of the utility supply system for milk powder production. Sequentially explored opportunities are: (1) increasing boiler efficiency through condensing economisers, (2) waste heat recovery from the chiller unit, and (3) Combined Heat and Power (CHP) for electricity production. The basis for the analysis is the anticipated future milk powder process design, which incorporates results from recent studies that have focused on improving the process design and integration of the heat treatment and evaporator systems and recovering heat from the spray dryer exhaust, which show a combined specific fuel consumption reduction of 29.6 % and a relatively small increase in electricity use of 4.5 %. To maximise boiler efficiency, the study concludes that a condensing economiser for the flue gas can be indirectly matched with heating fluidised bed air flows through the boiler condensate system, which results in specific fuel use reduction of 227 MJ/tp. Chiller waste heat can be upgraded and integrated as a heat source to replace the equivalent specific fuel use of 101 MJ/tp through integration with the site low temperature hot water loop. By designing the steam system to maximise electricity generation in a new turbine, results show that 51 % of the site’s electricity demand may be satisfied by CHP. The combined effect of implementing these three utility systems opportunities is a specific fuel use of 3,868 MJ/tₚ, of which 530 MJ/tₚ result from electricity production, and a specific grid electricity demand of 113.4 kWh/tₚ.

title: Te taiao: Te titiro a te Māori

authors: Kirby, Dean Robert

subjects: Cosmology

abstract: Ko te kaupapa o tēnei tuhinga ko te titiro a te Māori ki te taiao. He mea tuhi i runga i te aroha, i te whakapono ki ngēnei mea, ki te ātaahua o te taiao me ngā kōrero mōna. E whakatangatatia ana ngā āhuatanga o te taiao, ngā rākau, ngā manu, ngā ika, te kohu, ngā kapua, ngā maunga, otirā ngā mea katoa. Ara noa atu ngā kōrero, he whakapapa ō rātou, he huānga tētehi mea ki tētehi, he mauri tō tēnā mea tō tēnā mea. E ora ana ngā mea katoa o te ao, ka whai tamariki, he mātua he tūpuna anō, te katoa tae atu hoki ki te tangata, he wāhanga ia nō te taiao.
Hei aha tēnei tuhinga? Ko tāna mahi he whakaatu i ngēnei āhuatanga. Ā he whakamātau hoki ki te whakautu i te pātai he aha i whērā ai te titiro a ngā tūpuna ki tō rātou taiao. He kohikohingā tēnei nō ngā kōrero maha e takoto mai naka i roto i ngā pukapuka kua tāia kētia. Ehake i te mea ka kōrerotia ngā mea katoa, otiia ka tirohia noatia ngētehi āhuatanga o tēnei hanga te taiao. Kāhore i tuhia i runga i ngā kōrero ā waha a ngētehi kaikōrero, whēnā i ngētehi atu tuhinga roa. He mahi nui tērā mā tētehi atu hei whai, heoi anō tēnei he huihuinga nō ngētehi kōrero kua tuhia i mua atu.
Ka whakarārangitia ngā kōrero neki i muri ake nei. Ko tōna timatanga kei te Ōrokohanga, ko te timatanga tērā o te taiao. Ko te whenua ka whai mai me ngā kōrero mōna. Muri iho ko te wai me ngōna āhuatanga katoa. Ko te rangi, ngā mea katoa o te rangi ka whai mai i muri i tēnā. Muri iho anō ko ngā manu, ko ngā ngārara me ngā ngāngara, ngā rākau me ngā ika. Ka mutu atu i ngā tupua, i ngā taniwha me ngā patupaiarehe, i ngā kōrero mō ngērā. E iwa wāhanga nui te katoa o tēnei tuhinga. Kei te timatanga tētehi wāhanga hei whakamārama i te tuhinga ā kei te mutunga tētehi atu wāhanga hei whakatōpū, hei whakarāpopoto i ngā kōrero o roto i te puku o te tuhinga nei.
Kei ngā wāhanga o te pukapuka nei he kōrero mō tēnā mea, mō tēnā mea i raro i tōna ūpoko anō, me ngā whakaāhua e rite ana mōna. Ko te tūmanako ka kite te kaipānui i te pūrotutanga o te taiao o te Māori.
