title: Globalization and economic geography: the world is curved, not flat

authors: McCann, P.

subjects: globalization

abstract: This paper analyses the argument put that the world is becoming flatter from the perspective of economic geography and spatial economics. In order to do this, we consider the variety of empirical evidence available, much of which appears to be prima facie rather paradoxical. However, it is possible to reconcile all of the seemingly conflicting the evidence by adopting the argument that the global economy simultaneously exhibits trends towards both increasing globalization and localization. Cities are increasingly seen to be the critical context for growth. Using diagrams, we demonstrate that analytically the global economy is becoming even more curved.

title: Relationship between manufacturing and properties of vacuum sintered Ti and Ti-6Al-7Nb

authors: Bolzoni, Leandro

abstract: Titanium alloys are ideal for a great range of engineering applications; however, their high manufacturing costs hinder their widespread use. This study investigates the relationship between the processing and properties of representative Ti-based materials manufactured via powder metallurgy in order to reduce the manufacturing costs. This is possible as powder metallurgy techniques are near-net shape processes with high yield of material. It is found that the relative density increases with the sintering temperature, and it is slightly higher for longer processing times, reaching values in the 94–97% range. Moreover, homogeneous microstructures are obtained for all the conditions investigated, achieving an equiaxed microstructure for Ti and the typical lamellar structure for the Ti-6Al-7Nb alloy. However, the increment of the temperature also leads to a higher amount of interstitial pick-up, with a maximum increment of 0.21 wt.% and 0.028 wt.% for oxygen and nitrogen, respectively. The highest properties achieved for Ti and Ti-6Al-7Nb are 272 HV (hardness), 17.9 W/m·K (thermal conductivity), and 62.7 μohm·cm (electrical resistivity) and 336 HV, 6.9 W/m·K, and 180 μohm·cm, respectively.

title: What does it take to make us listen? The experiences of those leading whole school reform to improve outcomes for indigenous minority students

authors: Buckley, Louise Jane

subjects: Education

abstract: This thesis examines how the Kia Eke Panuku: Building on Success school reform initiative shaped the experiences of groups of educators within mainstream New Zealand secondary schools. These experiences are analysed against a setting of colonisation and historic educational policies of assimilation and integration that have created a situation of education debt. The lack of power for Māori in education is evident. This study highlights the role of the Strategic Change Leadership Team in deconstructing power hierarchies within schools so that educational outcomes can be improved for Māori students. It presents the Strategic Change Leadership Team as the vehicle for conscientisation, resistance and transformative praxis within schools. It shows that in schools where power hierarchies were deconstructed, Māori students were able to enjoy educational success as Māori.
