Elegy to an Oz Republic: First Steps in a Ceremony of Invocation towards Reconciliation

In 2012 the author completed a series of drawings that, while figurative in form, were structurally based on and derived their inspiration from Robert Motherwell’s abstract series, Elegies to the Spanish Republic (1963-1975). This wholesale 'borrowing', 'quotation' and 'citation' raises the questions addressed in this article. What does it mean to engage in acts of appropriation now? And, more importantly, can such acts of appropriation draw on the spirit of the 'original' work to make a (political) difference? 

A material model for warm forming of aluminium sheet

A material model has been developed to simulate the warm forming of Al–Mg\ud sheet. Both the hardening behaviour, including temperature and strain rate effects, and the\ud biaxial stress–strain response of the sheet are considered. A physically-based hardening model\ud according to Bergström is used. This model incorporates the influence of the temperature\ud and strain rate on the flow stress and on the hardening rate based on dynamic recovery. For\ud deformations at constant temperature and strain rate, the Bergström model reduces to the well\ud known Voce hardening model. The Bergström/Voce models can be fitted quite well to the results\ud of monotonic tensile tests of an AA 5754-O alloy.\ud The biaxial stress–strain response of the material is experimentally determined by uniaxial,\ud plane strain, simple shear and equi-biaxial stress tests. It is demonstrated that the widely used\ud Hill ’48 yield locus is inappropriate for simulation of deformation of aluminium. The low Rvalues\ud for aluminium lead to a significant underestimation of the equi-biaxial yield stress. In\ud the simulation of the deep drawing of a cylindrical cup this results in a much too thin bottom of\ud the cup. The Vegter yield criterion is sufficiently flexible to accurately represent the shape of the\ud yield locus and the anisotropy.\ud

Determinants of neighbourhood satisfaction and perception of neighbourhood reputation

It has been suggested that the residential mobility behaviour and general well-being of residents of urban neighbourhoods are not only influenced by how residents themselves assess their neighbourhood, but also by how they think other city residents see their neighbourhood: the perceived reputation of the neighbourhood. There is a large body of literature on residents' satisfaction with their neighbourhood, but much less is known about how residents perceive the reputation of their own neighbourhood. Such knowledge might give important clues on how to improve the well-being of residents in deprived neighbourhoods, not only by directly improving the factors that affect their own level of satisfaction, but also by improving the factors that residents think have a negative effect on the reputation of their neighbourhood. This paper examines whether there are differences in the determinants of neighbourhood satisfaction and the perceived reputation of the neighbourhood. Using data from a purpose-designed survey to study neighbourhood reputations in the city of Utrecht, the Netherlands, it is found that subjective assessment of the dwelling and neighbourhood attributes are more important in explaining neighbourhood satisfaction than in explaining perception of reputation. Objective neighbourhood variables are more important in explaining perception of reputation than in explaining neighbourhood satisfaction.PostprintPeer reviewe

Rhythm and the Performative Power of the Index: Lessons from Kathleen Petyarre's Paintings

Is it possible to find an ethical and generative way to speak about the ‘work’ of Indigenous art? Regardless of what prohibitions exist to protect sacred knowledge from the gaze of Western eyes, Indigenous work is circulating; it is being read, misread, interpreted, misinterpreted and otherwise known. How can a non-Indigenous person ‘speak’ about Indigenous art without reducing it to the diagram, collapsing it into Western modes of knowing, or intruding into the domain of restricted cultural information? Given the lessons of the Indigenous cultural practices, I propose that the work of art is performative and not merely representational. Through attention to the operation of rhythm in Kathleen Petyarre’s paintings, I propose to reconfigure contemporary understandings of performativity. In this formulation I will argue that in the dynamic productivity of the performative act, the world intrudes into practice, and in a double movement, practice casts its effects back towards the world. In this way I suggest that just as life gets into images, so imaging also produces reality. This mutual reflection is the work of art

The Association of Participant Characteristics and Service Delivery with Program Completion Rates for SafeCare in Georgia

Child maltreatment affects millions of children annually, and evidence-based home visiting programs, such as SafeCare®, help increase parenting skills and, ultimately, the well-being of children. Although effective at reducing maltreatment when participants complete services, high attrition rates in home visiting services may reduce this effectiveness. Using a sample of all clients receiving SafeCare services in Georgia (n=93) from October 2013 to February 2015, we evaluated individual characteristics, information seeking behaviors, and programmatic factors in order to understand the relationships, if any, with participant program completion. During this evaluation cycle, SafeCare reports a completion rate of 43%. The race of the primary guardian significantly relates to program completion (p=0.02). This evaluation can assist those implementing SafeCare to anticipate the needs of their target population
