title: Attaching negative structures to model cut-outs in the vibration analysis of structures

authors: Mochida, Yusuke

subjects: Science & Technology

abstract: The presence of a hole, cut-out or void in a structure makes it difficult to be modelled for calculating natural frequencies. A theoretical basis for simplifying the modelling of cut-outs in a structure by attaching a negative structure is presented. The Dynamic Stiffness Method has been used to prove that this method yields the required natural frequencies. The derivations also show the presence of additional natural frequencies which correspond to the vibration of the positive and negative parts vibrating together while the actual structure with the hole or cut-out usually remains stationary.

title: Learning, creative col(labor)ation, and knowledge cultures

authors: Peters, Michael A.

subjects: cybernetic capitalism

abstract: In this conversation, Michael A. Peters analyses the advent of knowl- edge cultures and their relationships to human learning. The first part of the conver- sation analyses social transformation towards the network society and links digital technologies to the making of the society of control. It analyses the dynamics between openness, capitalism, and anti-capitalism, and uses various recent examples to link that dynamics to democracy. The second part of the conversation links cybernetic capitalism to learning and knowledge production, and elaborates the movement of open education. Based on work of Paulo Freire, it develops the notion of openness as an (educational) virtue. It links openness and creativity, introduces Michael Peters’ political economy of academic publishing, analyzes the importance of editing for learning and knowledge production, and briefly introduces the concept of knowledge cultures. The third part of the conversation shows practical applications of these theoretical insights using the examples of two academic journals edited by Michael Peters: Knowledge Cultures (Addleton), and The Video Journal of Education and Pedagogy (Springer). It explores epistemic consequences of peer-to-peer and wisdom- of-the-group approaches, introduces the notions of collective intelligence and col- (labor)ation, and outlines the main features of the new collective imagination. Finally, it shows that doing science is a privilege and a responsibility, and points towards transformation of academic labor from perpetuation of capitalism towards subversion.

title: E tama Hikairo

authors: Maxwell, Te Kahautu

subjects: Oriori

abstract: He oriori tēnei mō Hikairo, te mokopuna tuatahi a Kīngi Tūheitia. He oriori tēnei e whakanui ana i a Hikairo, tōna whakapapa, tōna tūranga i te ao Māori me te ao Kīngitanga. He mokopuna Ringatū anō a Hikairo, nā Kīngi Tūheitia i tuku mai a Hikairo kia tūātia e Te Hāhi Ringatū ki te Poukai o Wāhi Pā i te tuawaru o Whiringa-ā-Nuku 2014. Ka whakaaturia tōna whakapono Hāhi Ringatū ki roto i te oriori nei e kupu whakaaritia ana. I tohua hoki e Kīngi Tūheitia a Te Kāhautu hai pou whakaruruhau1 mō Hikairo koinei ia i titoa ai tēnei oriori mō tana tamaiti mokopuna, mō Hikairo. He aroha nui nō te matua mō wai oti, mō Hikairo.

I titoa tēnei oriori hai waiatatanga mā te kapa haka o Ōpōtiki Mai Tawhiti. I waiatatia e Ōpōtiki Mai Tawhiti tēnei ki Te Matatini i tū ki Ōtautahi te tau rua mano tekau mā rima. He huarahi anō tēnei mā Te Kāhautu ki te whakamānawa i tana mokopuna i a Hikairo, nara nā te kapa haka a Te Kāhautu i waiata, i whakanui a Hikairo ki te maraenui o te iwi Māori, ko Te Matatini. Ana i tuatahi a Hikairo i te wehenga o Te Waiata Tira. “E Tama Hikairo, haere mai rā.”
