title: A bilinear pairing based secure data aggregation scheme for WSNs

authors: Kumar, Vimal

subjects: computer science

abstract: End to end secure data aggregation scheme for wireless sensor networks that are based on public key cryptography generally use elliptic curves. However elliptic curve based protocols require messages to be mapped to elliptic curves before performing any operations and finally reverse mapped to retrieve the message back. No mapping function, however, which is both homomorphic and has an efficient reverse mapping function is currently known. The mapping functions used in many previous protocols require brute forcing to reverse map the message from a point on the elliptic curve. This solution may be feasible on a base station with unlimited energy and processing power but it means that decrypting becomes very inefficient on ordinary sensors. We propose a secure data aggregation algorithm based on bilinear pairing that avoids this problem and makes decrypting data feasible on ordinary sensors.

title: Reflective practice: Dance-making and image narratives.

authors: Bright, Deborah Ann

subjects: reflective practice

abstract: In this paper I discuss the identification and representation of embodied knowing, focusing on how it is evidenced through reflective practice in dance-making. Grounded in a phenomenological hermeneutic approach, the research from which this discussion is drawn included the development of a model specific to reflective practice in dance-making and an exploration into alternative means of representing embodied knowing in dance-making. The outcome of this exploration is an image narrative which brings together dance-making, images and reflective journals.

title: Ko Waikato-Maniapoto te iwi

authors: Ngaia, Te Ingo Karangaroa Terehia

subjects: Waikato Maniapoto

abstract: Nō te ūnga mai o Tainui waka, i Whangaparāoa, ka tīmata i reira te tautapa haere a Tainui waka i tōna rohe, i tāna tere i Te Ika-ā-Māui. Nāwai rā ka tau ki tōna tumu i roto o Kāwhia Moana, Kāwhia Kai, Kāwhia Tāngata, i te taha hauāuru o Te Ika-ā-Māui. I roto i ngā rautau i muri mai i te ūnga o Tainui waka me ngā tūpuna i tere mai i te waka, ka tīmata ngā tūpuna te mātoro haere i te whenua hou me te whakanoho i ngō rātou whānau. Ka tupu i koneki ngā hapū me ngā iwi i heke mai i ngā waka. I roto i ngā tātai whakapapa o Tainu waka, e mārama mai ana ngā kāwai heke ki ngā iwi o Waikato me Maniapoto hoki. Ka whai mana ngā rangatira o ngā iwi nei i ngō rātou kāinga me ngā pānga whenua i noho ai rātou.
I hua tuatahi ai te iwi o Waikato-Maniapoto i roto i ngā pakanga me ngā whakaipoipotanga mo ngā kāinga me ngā pānga whenua, kai, moana hoki. Nā ngā pūkenga wānanga, pakanga hoki, i whakawehe, i kotahi ai rānei ngā iwi.
I te taenga mai o te Pākehā ki te pēhi i ngā tikanga a te Māori, ka huri te aro o te Pākehā ki te whakahau me te whakawai i ngā rātou tauira hou ki runga i ngā iwi.
Ka whakaturengia ngā ingoa o ngā tikanga hou, nā te Kāwanatanga Pākehā hou nei i whakamana, ā, i whakaū ngēnei tikanga hou kia pēhia ngā tikanga taketake ake a te Māori. Ka huri a Waikato-Maniapoto iwi ki te aru i ngā tauira hou ki te whakawhanake i ngā uri whakatupu i roto i te ao hou. Hoi, i mau tonu i a Waikato-Maniapoto te wairua me ngā tikanga i heke iho ki ngōna uri.
Ka whakaūngia te wairua me ngā tikanga o ngā mātua tūpuna ki roto i te tauira hou o te Kīngitanga. Ka mahi ngātahi te Kīngitanga me te iwi o Waikato-Maniapoto ki te whakatinana i tōna kaupapa, arā, hei pupuru i te toto; hei pupuru i te whenua; ā, hei pupuru i te mana Māori motuhake. I roto i te Kīngitanga nga 
hanganga iwi hou i puta hei kōkiri i ngā rautaki whakawhanake i te iwi whānui i roto i te ao hou nei.
Huhua noa atu ngā uri o Waikato-Maniapoto i whai wāhi i runga i ngā tūranga whakawhanake i te iwi whānui mā te whakaū i te mana Māori motuhake i roto i te reo me ngā tikanga o Waikato-Maniapoto iwi me ngōna kaupapa. Ko te whakahua i ngā hononga iwi kia whai whanaungatanga, kia whai tūrangawaewae te whakatinanatanga o te whakapono ā-wairua nei ki ngā taonga tuku iho o Waikato-Maniapoto. Ka whai mana, ka tūturu te kīanga a Waikato-Maniapoto i roto i te whakamana a ngā uri i ngā kōrero whakapapa o te iwi o Waikato-Maniapoto me te whakamana i te kīanga nei i ngā reanga whakapapa.
