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.

The Dutch Obesity Intervention in Teenagers (DOiT) cluster controlled implementation trial: intervention effects and mediators and moderators of adiposity and energy balance-related behaviours

 Background: The Dutch Obesity Intervention in Teenagers (DOiT) programme is an evidence-based obesity prevention programme tailored to adolescents attending the first two years of prevocational education in the Netherlands. The initial programme showed promising results during an effectiveness trial. The programme was adapted and prepared for nationwide dissemination. To gain more insight into the process of translating evidence-based approaches into ‘real world’ (i.e., ‘natural’) conditions, our research aims were to evaluate the impact of the DOiT-implementation programme on adolescents’ adiposity and energy balance-related behaviours during natural dissemination and to explore the mediating and moderating factors underlying the DOiT intervention effects.
Methods: We conducted a cluster-controlled implementation trial with 20 voluntary intervention schools (n=1002 adolescents) and 9 comparable control schools (n = 484 adolescents). We measured adolescents’ body height and weight, skinfold thicknesses, and waist circumference. We assessed adolescents’ dietary and physical activity behaviours by means of self-report. Data were collected at baseline and at 20-months follow-up. We used multivariable multilevel linear or logistic regression analyses to evaluate the intervention effects and to test the hypothesised behavioural mediating factors. We checked for potential effect modification by gender, ethnicity and education level.
Results: We found no significant intervention effects on any of the adiposity measures or behavioural outcomes. Furthermore, we found no mediating effects by any of the hypothesised behavioural mediators. Stratified analyses for gender showed that the intervention was effective in reducing sugar-containing beverage consumption in girls (B = -188.2 ml/day; 95% CI = -344.0; -32.3). In boys, we found a significant positive intervention effect on breakfast frequency (B = 0.29 days/week; 95% CI = 0.01; 0.58). Stratified analyses for education level showed an adverse intervention effect (B = 0.09; 95% CI = 0.02; 0.16) on BMI z-scores for adolescents attending the vocational education track.
Conclusions: Although not successful in changing adolescents’ adiposity, the DOiT-implementation programme had some beneficial effects on specific obesity-related behaviours in subgroups. This study underlines the difficulty of translating intervention effectiveness in controlled settings to real world contexts. Adaptations to the implementation strategy are needed in order to promote implementation as intended by the teachers.

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

Tourism, Dutch disease and welfare in an open dynamic economy

This chapter examines the effects of an expansion in tourism on capital accumulation, sectoral output and resident welfare in an open economy with an externality in the traded good sector. An expansion of tourism increases the relative price of the non traded good, improves the tertiary terms-of-trade and hence yields a gain in revenue. However, this increase in the relative price of non traded goods results in a lowering of the demand for capital used in the traded sector. The subsequent de-industrialization in the traded good sector may lower resident welfare. This result is supported by numerical simulations. © 2011 Nova Science Publishers, Inc.
