title: Dancing national Identity: The evolution of meta-narratives in Colombian and Filipino Folk Dance

authors: Diaz Rodriguez, José M.

subjects: Bambuco

abstract: The Philippines and Colombia share a history of colonial conquest from the same country, Spain. This shared history has influenced the ways in which folk dance has developed. Both countries have a wide folk repertoire, some of which reflects the different ways in which Spanish source material has been processed, adapted, and fused with local material to represent ways in which the past is remembered. Despite the apparent disparity, two dances in particular, the Cariñosa in the Philippines, and the Bambuco in Colombia, share similar features in terms of their choreographic material and narratives. This article explores several meta-narratives in both sets of dances, and the politics of memory behind them, through an interdisciplinary approach, intertwining cultural representation and choreographic politics. Included in this comparative exploration are the choices towards reflecting local identities through folk dance and some of the implications of these representations in both physical and political terms.

title: The linear stability of line-tied coronal magnetic fields

authors: Foote, B.J.

abstract: The problem of the linear stability of cylindrically symmetric force-free magnetic equilibria is addressed. The aim is to quantify the severity of ideal MHD disturbances on a variety of line-tied coronal equilibria. Accordingly methods are developed which determine, at high spatial resolution, the dominant eigenmodes of the problem. We first introduce a family of equilibrium force-free fields parameterized by the local dimensionless twist T = rν which includes the well-known Gold-Hoyle field in the case ν = 0. The stability problem is then formulated, and the numerical techniques required for its solution are derived. As a preliminary test of our methods we present convergence results for the critical length of the Gold-Hoyle field, obtaining the result lc = 2.46π (dimensionless units). Next, the severity of the instability is quantified. The kink instability (m = 1) is found to be weak even for long lengths (l ≳ 4lc), generating dimensionless force eigenvalues less than O(10-2). The Gold-Hoyle field is shown to be the most unstable member of the family for large l, yet is the most susceptible to line-tying and so possesses the longest critical length. Preliminary investigations for higher m have not yielded instabilities for the moderate tube lengths of interest. The significance of these results to flare theories cannot be known definitively without results from finite-amplitude studies. Our results show, however, that the power release over the linear phase is at least three orders of magnitude below dimensional expectation. This implies that unstable coronal flux tubes cannot be expected to collapse violently on the MHD time scale.

title: How usable is a smartphone with a Māori-language interface?

authors: Mato, Paora James

subjects: Mäori

abstract: Major languages dominate contemporary technologies. For Mäori, there is opportunity to engage with some technologies using their language and to participate within Mäori- language communities in various digital media. A smartphone launched by Two Degrees Mobile Limited provides a Mäori- language interface option. An initial pilot study indicated users will engage with this interface, but when pushed for time will switch the interface to the English- language option. This paper reports on a study undertaken to test the usability of the smartphone Mäorilanguage interface. Participants reported diffi culties and some frustration as they struggled with new words and unfamiliar uses of words. They also expressed disappointment at poor translations and arbitrary truncations. The feedback highlights perceived shortcomings encountered when technologies that are normally developed and used in a major language are translated for use in minority Indigenous languages. Mäori-language strategies that consider using translated application interfaces should be cognisant of such issues.
