Resisting the Far-Right: Indigenous Perspectives, Community Arts and Story-Based Strategy
This article explores how we might resist and confront anti-immigration and anti-refugee politics by addressing the social and historical well-spring from which these discriminatory and damaging politics emerge and take sustenance. In doing this, I draw upon the concept of story-based strategy and the idea that our potential to address this issue relies on our capacity to fundamentally shift the dominant ways in which people understand and engage with it. This discussion occurs with reference to one practical application of story-based strategy – a community-arts project titled Stories of Hope and Migration – which attempted to re-frame the migration and refugee debate in Australia by funnelling it through a localised Indigenous perspective. In so doing, this article challenges the way in which early British migrants and their descendants have continually excised themselves from the rhetoric of migration, and furthermore, suggests that through a more nuanced conversation regarding the migration stories of all non-Aboriginal people, we might better promote a more historically aware, compassionate and inclusive society
Non-commutativity and non-associativity of the doubled string in non-geometric backgrounds
We use a T-duality invariant action to investigate the behaviour of a string
in non-geometric backgrounds, where there is a non-trivial global
patching or monodromy. This action leads to a set of Dirac brackets describing
the dynamics of the doubled string, with these brackets determined only by the
monodromy. This allows for a simple derivation of non-commutativity and
non-associativity in backgrounds which are (even locally) non-geometric. We
focus here on the example of the three-torus with H-flux, finding
non-commutativity but not non-associativity, and also comment on the relation
to the exotic brane, which shares the same monodromy.Comment: 31 pages, v2: refs added, corrections to sec 5, results updated, v3:

Integrated series active filter for aerospace flight control surface actuation
The paper investigates integrated series active filters to satisfy aircraft power quality benchmarks and underlying design compromises. Advantages include reduced component count and retrofitting capability. Further insights into the merits of the proposed solution are included, along with representative results from a prototype system
Conserved Currents of Double Field Theory
We find the conserved current associated to invariance under generalised
diffeomorphisms in double field theory. This can be used to define a
generalised Komar integral. We comment on its applications to solutions, in
particular to the fundamental string/pp-wave. We also discuss the current in
the context of Scherk-Schwarz compactifications. We calculate the current for
both the original double field theory action, corresponding to the NSNS sector
alone, and for the RR sector.Comment: 30 pages + appendix, v2: belated update to match published version
