title: Approximative filtering of XML documents in a publish/subscribe system

authors: Hinze, Annika

subjects: computer science

abstract: Publish/subscribe systems filter published documents and inform their subscribers about documents matching their interests. Recent systems have focussed on documents or messages sent in XML format. Subscribers have to be familiar with the underlying XML format to create meaningful subscriptions. A service might support several providers with slightly differing formats, e.g., several publishers of books. This makes the definition of a successful subscription almost impossible. This paper proposes the use of an approximative language for subscriptions. We introduce the design of our ApproXFilter algorithm for approximative filtering in a publish/subscribe system. We present the results of our performance analysis of a prototypical implementation.

title: Using apps for teaching and learning mathematics: A socio- technological assemblage

authors: Calder, Nigel Stuart

abstract: This paper reports on an aspect of a research project that examined the use of apps in primary school mathematics programmes. It reports teacher and student perspectives on how they used a range of digital tools within the apps to solve problems. We consider the interplay between the affordances of the mobile technologies, including multi- representation and haptic, with other social and pedagogical aspects, and how the assemblage of social and technological entities influences the ways that teachers might integrate apps into their mathematics programmes.

title: Mōteatea: He pātaka whakairinga kōrero nō Ngāti Rangiwewehi

authors: Paterson, Awatea

subjects: Ngāti Rangiwewehi

abstract: Mai rā anō a Ngāi Tāua, te iwi Māori, e tuku iho ai i ngā mātauranga mā te ārero tupuna mai i tētehi whakatupuranga, ki tētehi whakatupuranga. Ko ngā mātauranga ka tukua iho ko ngā pūrākau, ko ngā karakia, ko ngā whakataukī, ā, ko ngā waiata hoki. Ko te pūtake o te rangahau nei he titiro pū ki te āhua o te noho o ngā mōteatea hei pātaka whakairinga kōrero mō Ngāti Rangiwewehi ake, nō reira ka āta tirohia ngā momo puna mōhiohio, ngā momo kura aweko ka whakairia ki te pakitara o te pātaka kōrero o Ngāti Rangiwewehi. Nā ngā mōteatea i tohu te wā, i kōrero mō te wāhi, i whakapūkete ngā mahi a ngā tūpuna o te wā i titoa ai te mōteatea. Nā, ko ngā waiata, ko ngā mōteatea koirā te ara whakapūkete kōrero ka wānangahia e te tuhinga nei. Mā te āta wetewete i tētehi mōteatea pū o Ngāti Rangiwewehi, ka hora i ngā kura āuki, i ngā māpihi pounamu, i ngā puna mātauranga o te iwi kua whakaemi mai ki roto i te mōteatea hei kōrero tuku iho mō te iwi o Ngāti Rangiwewehi, hei whakatauira ake hoki i te āhua o te noho o ngā mōteatea hei ara whakapūkete mātauranga.
