There is a long-standing debate concerning the suitability of European or ‘western’ approaches to the conservation of cultural heritage in other parts of world. The Cultural Charter for Africa (1976), The Burra Charter (1979) and Nara Document on Authenticity (1994) are notable manifestations of such concerns. These debates are particularly vibrant in Asia today. This article highlights a number of charters, declarations and publications that have been conceived to recalibrate the international field of heritage governance in ways that address the perceived inadequacies of documents underpinning today’s global conservation movement, such as the 1964 Venice Charter. But as Venice has come to stand as a metonym for a ‘western’ conservation approach, intriguing questions arise concerning what is driving these assertions of geographic, national or civilisational difference in Asia. To address such questions, the article moves between a number of explanatory frameworks. It argues declarations about Asia’s culture, its landscapes, and its inherited pasts are, in fact, the combined manifestations of post-colonial subjectivities, a desire for prestige on the global stage of cultural heritage governance and the practical challenges of actually doing conservation in the region.

The track cycling Omnium is a multi-event competition that has recently been expanded to include the Elimination Race (ER), which presents a unique set of physical and tactical demands. The purpose of this research was to characterise the performance attributes of successful and unsuccessful cyclists in the ER, that are also predictive of performance. Video recordings of four international level ERs were analysed. The performance attributes measured related to the cyclists’ velocity and two dimensional position in the peloton. The average velocity of the peloton up to lap 30 (of 50) was relatively high and consistent (52.2±1.5 km/h). After lap 30, there was a significant (p<0.001) change in velocity (49.9±2.4 km/h), characterised by more fluctuations in lap-to-lap velocity. Successful ER cyclists adopted a tactic of remaining in the middle of the peloton, in the lower lanes of the velodrome, thus avoiding the risk of elimination at the rear and the extra effort required to remain on the front of the peloton. Unsuccessful cyclists tended to reside in the rear and upper (higher) portions of the peloton, risking elimination more often and having to ride faster than those in the lower lanes of the velodrome. The physiological demands of the Elimination Race that are determined by velocity, vary throughout the Elimination Race and the pattern of movement within the peloton is different for successful and unsuccessful cyclists. The findings of the present study may confirm some aspects of race tactics that are currently thought to be optimal, but they also reveal novel information that is useful to coaches and cyclists who compete in the Elimination Race.

Results of a numerical exercise, substituting a numerical operator by an artificial neural network (ANN) are presented in this paper. The numerical operator used is the explicit form of the finite difference (FD) scheme. The FD scheme was used to discretize the one-dimensional transport equation, which included both the advection and dispersion terms. Inputs to the ANN are the FD representation of the transport equation, and the concentration was designated as the output. Concentration values used for training the ANN were obtained from analytical solutions. The numerical operator was reconstructed from a back calculation of the weights of the ANN. Linear transfer functions were used for this purpose. The ANN was able to accurately recover the velocity used in the training data, but not the dispersion coefficient. This capability was improved when numerical dispersion was taken into account; however, it is limited to the condition: C/P<0.5 , where C is the Courant number and P , the Peclet number (i.e., the restriction imposed by the Neumann stability condition).

Social scientists and Indigenous people have voiced concerns that media messages about genetics and race may increase the public's belief in genetic determinism and even increase levels of racism. The degree of genetic determinism in media messages has been examined as a determining factor. This study is the first to consider the implications of this area of scholarship for the indigenous minority in Australia. A search of the last two decades of major Australian newspapers was undertaken for articles that discussed Indigenous Australians and genetics. The review found 212 articles, of which 58 concerned traits or conditions that were presented in a genetically deterministic or antideterministic fashion. These 58 articles were analysed by topic, slant, and time period. Overall, 23 articles were anti-deterministic, 18 were deterministic, 14 presented both sides and three were ambiguous. There was a spike in anti-deterministic articles in the years after the Human Genome Diversity Project, and a parallel increase in deterministic articles since the completion of the Human Genome Project in 2000. Potential implications of the nature of media coverage of genetics for Indigenous Australians is discussed. Further research is required to test directly the impact of these messages on Australians.

The aim of this paper is to support critical and scholarly debates that relate to the increasing role of visual research in education, youth studies, sociology, and studies of mental health. Researching in fields where young people are central exposes many struggles, not least issues of how to represent students who end up on the margins. School disaffection intersects with curriculum practices. When threading together visual research methods and matters of curriculum studies, seduction can set in, and unintentionally curriculum research can become indifferent to difference, the counterpoint often sought by researchers. Some scholars may argue that this debate has been well rehearsed in the curriculum field; I, however, take the opposite view. The constraints of curriculum studies, issues of student disaffection and the exclusions of schooling - when analysed through the perspectives of visual research - trouble our research designs and understandings of data and therefore require more, not less, interrogation. Rethinking the intersection points between visual research methods (VRM) and visuality, a concept that is critical to cultural and visual studies, opens out new spaces in the field of curriculum studies and reframes the methodological decisionmaking process for researching issues that pertain to student disaffection.

Background
Since the introduction of the renal access coordinator (RAC) role into Australia there have been only anecdotal examples of associated improvements in patient outcome and service delivery and scant published quantitative extant evidence exists.

Aim
To review the literature related to the impact of RACs on dialysis patient outcomes and associated service delivery, gauge the level of evidence available and identify gaps in the literature.

Method
A three stage Joanna Briggs Institute (JBI) systematic review process was used to collect and synthesise data. The review considered studies that explored and measured the RAC role in the adult haemodialysis context. All quantitative study designs were considered. Due to lack of homogeneity a narrative synthesis was undertaken.

Results
Five studies met the inclusion criteria for the review. All studies included multidisciplinary teams with variable emphasis on the RAC role. Four pre post intervention cohort studies measured incident and/or prevalent AVF, AVG and CVC rates in the haemodialysis population and the quality assurance report measured differences in patency rates between AVF and AVG and associated hospital length of stay. All discussed the role of central coordination as a contributor to the success of vascular access care.

Conclusion
The available reports do suggest an association between RACs and improved patient outcomes. These improved patient outcomes were apparent in an increase in incident and prevalent AVFs, and a decrease in the incidence and prevalence of CVCs. Both associations are correlated with a reduction in infection rates, length of hospital stay and healthcare costs
