Drawing the line: Chinese calligraphy, cultural materialisms and the “remixing of remix"

Remix in writing has very different expressions, and is grounded in very different legal, philosophical and creative materialisms, in Western and Chinese cultures. The infringement of authors’ Intellectual Property Rights (IPRs) in China is not only an irritant for Chinese-Western commercial and legal relations. It also points to different formations of the creative and legal domains across global space, and serves to introduce notions of creativity and originality that are largely unfamiliar in the West. Calligraphy, as a pictorial and material mode of writing, comprises a practice of Chinese remix in which the apprentice traces the lines of the master’s work: repetition of Yun 韵 (‘composed body movements’) stimulates the expression of Qing 情 (‘feelings’). What appears from a distance to be slavish imitation actually involves a philosophy of learning (or more precisely, of ‘unlearnt learning’) that, bypassing plagiarism’s traps, effectively ‘remixes remix’ as a creative model no longer dependent on the familiar Western rationales for the legitimacy of remix as appropriation, homage and/or pastiche. To see this though, one has to deploy a Taoist rather than a Confucian framework in the analysis of calligraphic practices. The case of Kathy Acker, allied with the work of Gilles Deleuze, reveals a largely invisible lineage of Taoist-influenced remix in Western creative writing. In this way, calligraphy emerges as a model of remix relevant to all forms of writing—for all writing is material, whether calligraphic or not. Further, as Acker shows, the materiality of writing constantly replenishes its remixing with cultural elements that may not be otherwise visible.

Mental context reinstatement or drawing: which better enhances children's recall of witnessed events and protects against suggestive questions?

The aim of this experiment was to examine the effectiveness of two techniques in enhancing children's recall of an event that they experienced approximately a week earlier. Younger (5–6 years) and older (8–9 years) children were interviewed about a magic show event in one of three conditions. Before recalling the event, some children were instructed to mentally reinstate the context of the event (MCR group), others were asked to draw the context of the event (DCR group), and others received no reinstatement instructions (NCR). Results showed that these instructions had no impact on children's free recall or responses to open-ended prompts. However, reinstatement instructions impacted children's responses to suggestive questions: those in the DCR group gave more accurate responses than those in the NCR group. These findings provide preliminary support for the use of drawing as a potentially protective exercise that lessens the impact of biased questions with child witnesses.

Polyacrylonitrile nanofibre yarn; electrospinning and their post-drawing behaviour

Polyacrylontrile nanofibre yarns have been successfully produced from an electrospinning setup composing positively and negatively charged spinnerets, a rotating funnel and a yarn winder. Through hot drawing, yarns show compact morphology and improved uniformity and have a significant decrease in both yarn and fibre diameters. The hot drawing has improved the molecular orientation and crystallinity of the fibres. The yarn drawn to 5 times of its original length has been found to have the highest tensile strength and modulus.

Benchmark 4 : wrinkling during cup drawing

Benchmark-4 is designed to predict wrinkling during cup drawing. Two different punch geometries have been selected in order to investigate the changes of wrinkling amplitude and wave. To study the effect of material on wrinkling, two distinct materials including AA 5042 and AKDQ steel are also considered in the benchmark. Problem description, material properties, and simulation reports with experimental data are summarized.

Continuous polyacrylonitrile nanofiber yarns: Preparation and dry-drawing treatment for carbon nanofiber production

Precursor fibers with diameters in nanometer scale and highly aligned polymer chains in fibers are highly promising for the preparation of high-performance carbon nanofibers, but are challenging to make. In this study, we demonstrate for the first time that a carbon nanofiber precursor can be prepared by the electrospinning of polyacrylonitrile into a nanofiber yarn and by the subsequent drawing treatment of the yarn in dry conditions. The yarn shows excellent drawing performance, which can be drawn evenly up to 6 times of its original length without breaking. The drawing treatment improves the yarn and fiber uniformity, polymer chain orientation within the fibers, as well as yarn tension and modules, but shows decreased yarn and fiber diameter and elongation at break. The drawing temperature and force show influences on the drawing behavior. The highest strength and modules (362 ± 37 MPa and 9.2 ± 1.4 GPa, respectively) are found on the yarn drawn by 5 times its length, which increased by 800% and 1800% when compared to the as-spun yarn. Through un-optimized stabilization and carbonization treatments, we further demonstrate that the carbonized nanofiber yarn shows comparable tensile properties as the commercial carbon fibers. Electrospun nanofiber yarns may form next generation precursors for making high performance carbon fibers. This journal is

Place-based initiatives to tackle mature-age workers’ long-term unemployment in Australia, drawing on successful Nordic precedents

In order to tackle unemployment for the at-risk group of mature-age workers displaced by industry sector restructuring, exemplary place-based initiatives are needed focusing on a selected area of high disadvantage identified by Professor Tony Vinson’s 2015 Jesuit Social Services report Dropping off the Edge, with an Australian state government committed to supporting the initiative, as that report recommends. In order to make such a place-based initiative exemplary in its outcomes, so that it leads to uptake in other areas of high disadvantage, it needs to be thoroughly informed by successful Nordic precedents. In particular, the new Australian place-based initiative needs to be informed by Danish regionally-focused large-scale job skills programs involving transition into a proximate sector of employment growth; and by Norwegian measures for more even population distribution outside capital cities or in particular hard-hit regions within capital cities. An advantage of the proposed initiative is that it will also produce measurable results for children in families in which neither parent works, whose needs are normally tackled (if at all) by separate policy actions in separate tiers or departments of government. Australian children are disproportionately disadvantaged by the internationally extreme concentration of joblessness. Denmark’s Løntilskud and Virksomhedspraktik job training programs subsidised by municipalities and the national government, and supported by Danish trade unions, will be discussed in this paper for the positive effects they have for participants, including establishing or re-establishing unemployed people’s structured work habits and routines, improving their networks along with their social skills, and boosting their confidence. This paper will outline in detail the types of features the proposed new Australian place-based initiative will require, drawing on and drilling down further into data and analysis presented in the author’s recent book: Northern Lights: The Positive Policy Example of Sweden, Finland, Denmark and Norway.

Study on yield function and plastic potential under non-associated flow for accurate earing prediction in cup drawing

Prediction of more than four ears in a cup drawing process can be successfully achieved by considering r-value and stress directionalities. Yld2004-18p based on associated flow rule and Yld2000-2D based on non-associated flow rule are the examples. The former, however, is more costly in terms of computational efficiency than the latter. In this work, an anisotropic constitutive model based on non-associated flow rule which combines two different functions, Hill (1948) and Yld2000-2d, is implemented to a user defined material model. The accuracy of the anisotropic directionalities (yield stresses and plastic strain ratios) is evaluated. Simulation of a mini-die cup drawing with a body stock alloy predicted eight ears, in good agreement with the experimental results. The use of Hill (1948) model for the yield function and Yld2000-2d for plastic potential under the framework of non-associated flow rule led to accurate prediction of up to eight ears at the lower computational cost.
