title: Tensile Properties and Fracture Behaviour of Induction Sintered Ti and Ti-6Al-4V (wt %) Powder Compacts

authors: Raynova, Stiliana (Stella) Rousseva

subjects: Titanium alloys

abstract: Induction heating of powder compacts could be a very effective method for metal powder consolidation to get the final product or as an intermediate consolidation step to produce feedstock for metal powder forging or extrusion. Our study has proven that only a few minutes of induction heating, of Ti and Ti-6Al-4V (wt %) powder compacts, increases their density dramatically and causes a significant sintering effect, as evidenced by the formation of interparticle diffusion bonding and reflected by the tensile properties of the induction sintered powder compacts. This paper presents and discusses the results of a study on the tensile properties and fracture behaviour of the Ti and Ti-6Al-4V powder compacts sintered under a variety of induction heating conditions. Keywords: Titanium alloys, powder consolidation, powder compact sintering, induction heating.

title: Terrorism and religious fundamentalism: Prospects for a predictive paradigm

authors: Pratt, Douglas

subjects: religion

abstract: Although fundamentalism is neither new nor limited to one culture, globalized communications and recent political events have highlighted Christian and Muslim forms. Since links are often perceived between fundamentalism, extremism and terrorism, most commonly with respect to Islamic fundamentalism, it is desirable to delineate a model of fundamentalism which permits some degree of prediction as to its possible extension into political action. The term ‘religious fundamentalism’, it is argued here, can denote a type of worldview that can in fact be found in various religions of the world of today. Specifically, it may denote a shift in mentality from the relative harmlessness of an otherwise quaint, ultra-religious belief system to the readiness to pursue aggressively impositional, and in some cases terrorist activity. The article seeks to work out the details of these potential connections paradigmatically.

title: A Mātauranga Māori Perspective of Literacy for Adult Learners

authors: Furness, Jane Amanda

abstract: Globally, literacy can be conceived of in different ways. Two perspectives that have influenced adult literacy policy internationally are the economic functionalist and the sociocultural. In Aotearoa New Zealand, Māori educators have repeatedly advanced a mātauranga Māori perspective of literacy. This perspective has parallels with the embodied, practice-based multiliteracies and sociomateriality of the sociocultural perspective but less so with the dominant functionalist perspective. To address how Māori views have been side-lined in adult literacy policy development, we seek to clarify this view and foreground Māori-led policy recommendations that date back to the creation of the New Zealand Adult Literacy Strategy in 2001. We also highlight the relevance of this perspective by sharing the success and effectiveness of Māori-led adult literacy programmes. In doing so, we demonstrate the need for a biliteracy approach to adult literacy policy to reflect our bicultural nation and ensure Māori aspirations for literacy are met.
