The 4th Knowledge Cities World Summit Proceedings

FROM KCWS 2011 CHAIRS AND SUMMIT PROCEEDING EDITORS In recent years, with the impact of global knowledge economy, a more comprehensive development approach has gained significant popularity. This new development approach, so called ‘knowledgebased development’, is different from its traditional predecessor. With a much more balanced focus on all of the four key development domains – economic, enviro-urban, institutional, and sociocultural – this contemporary approach, aims to bring economic prosperity, environmental sustainability and local institutional competence with a just socio-spatial order to our cities and regions. The ultimate goal of knowledge-based development is to produce a city purposefully designed to encourage the continuous production, circulation and commercialisation of social and scientific knowledge – this will in turn establish a ‘knowledge city’. A city following the ‘knowledge city’ concept embarks on a strategic mission to firmly encourage and nurture locally focussed innovation, science and creativity within the context of an expanding knowledge economy and society. In this regard a ‘knowledge city’ can be seen as an integrated city, which physically and institutionally combines the functions of a science and technology park with civic and residential functions and urban amenities. It also offers one of the effective paradigms for the sustainable cities of our time. This fourth edition of KCWS – The 4th Knowledge Cities World Summit 2011 – makes an important reminder that the 'knowledge city' concept is a key notion in the 21st Century development. Considering this notion, the Summit sheds light on the multi-faceted dimensions and various scales of building a ‘knowledge city’ via 'knowledge-based development' paradigm by particularly focusing on the overall Summit theme of ‘Knowledge Cities for Future Generations’. At this summit, the theoretical and practical maturing of knowledge-based development paradigms are advanced through the interplay between the world’s leading academics’ theories and the practical models and strategies of practitioners’ and policy makers’ drawn from around the world. This summit proceeding is compiled in order to disseminate the knowledge generated and shared in KCWS 2011 with the wider research, governance, and practice communities the knowledge cocreated in this summit. All papers of this proceeding have gone through a double-blind peer review process and been reviewed by our summit editorial review and advisory board members. We, organisers of the summit, cordially thank the members of the Summit Proceeding Editorial Review and Advisory Board for their diligent work in the review of the papers. We hope the papers in this proceeding will inspire and make a significant contribution to the research, governance, and practice circles.

Disclosure of documents : production for inspection

In Altmann v Ioff of Victoria Friendly Society [2004] QDC 005 McGill DCJ considered the practical question in relation to disclosure of documents as to whether a party disclosing bundles of documents under UCPR r 217 was obliged to number or otherwise individually identify the documents

A broad-scale analysis of links between coastal fisheries production and mangrove extent : a case-study for northeastern Australia

The paradigm that mangroves are critical for sustaining production in coastal fisheries is widely accepted, but empirical evidence has been tenuous. This study showed that links between mangrove extent and coastal fisheries production could be detected for some species at a broad regional scale (1000s of kilometres) on the east coast of Queensland, Australia. The relationships between catch-per-unit-effort for different commercially caught species in four fisheries (trawl, line, net and pot fisheries) and mangrove characteristics, estimated from Landsat images were examined using multiple regression analyses. The species were categorised into three groups based on information on their life history characteristics, namely mangrove-related species (banana prawns Penaeus merguiensis, mud crabs Scylla serrata and barramundi Lates calcarifer), estuarine species (tiger prawns Penaeus esculentus and Penaeus semisulcatus, blue swimmer crabs Portunus pelagicus and blue threadfin Eleutheronema tetradactylum) and offshore species (coral trout Plectropomus spp.). For the mangrove-related species, mangrove characteristics such as area and perimeter accounted for most of the variation in the model; for the non-mangrove estuarine species, latitude was the dominant parameter but some mangrove characteristics (e.g. mangrove perimeter) also made significant contributions to the models. In contrast, for the offshore species, latitude was the dominant variable, with no contribution from mangrove characteristics. This study also identified that finer scale spatial data for the fisheries, to enable catch information to be attributed to a particular catchment, would help to improve our understanding of relationships between mangroves and fisheries production.

Identifying the key sociocultural influences on drinking behavior in high and moderate binge-drinking countries and the public policy implications

Despite considerable state investment and initiatives, binge drinking is still a major behavioral problem for policy makers and communities in many parts of the world. Furthermore, the practice of bingeing on alcohol seems to be spreading to young people in countries traditionally considered to have moderate drinking behaviors. Using a sociocultural lens and a framework of sociocultural themes from previous literature to develop propositions from their empirical study, the authors examine binge-drinking attitudes and behaviors among young people from high and moderate binge-drinking countries. The authors then make proposals regarding how policy makers can use social marketing more effectively to contribute to behavior change. Qualitative interviews were conducted with 91 respondents from 22 countries who were studying in two high binge-drinking countries at the time. The results show support for three contrasting sociocultural propositions that identify influences on binge drinking across these countries.

Australian content

There has long been widespread community, political and industry agreement over the important place of Australian content in the media mix, but debate continues over what counts as such in different media, how that content is defined, how much there should be, whether particular genres should be privileged, who should finance production, and how all of these things should be regulated.

Enhancing itaconic acid production by Aspergillus terreus

Aspergillus terreus is successfully used for industrial production of itaconic acid. The acid is formed from cis-aconitate, an intermediate of the tricarboxylic (TCA) cycle, by catalytic action of cis-aconitate decarboxylase. It could be assumed that strong anaplerotic reactions that replenish the pool of the TCA cycle intermediates would enhance the synthesis and excretion rate of itaconic acid. In the phylogenetic close relative Aspergillus niger, upregulated metabolic flux through glycolysis has been described that acted as a strong anaplerotic reaction. Deregulated glycolytic flux was caused by posttranslational modification of 6-phosphofructo-1-kinase (PFK1) that resulted in formation of a highly active, citrate inhibition-resistant shorter form of the enzyme. In order to avoid complex posttranslational modification, the native A. niger pfkA gene has been modified to encode for an active shorter PFK1 fragment. By the insertion of the modified A. niger pfkA genes into the A. terreus strain, increased specific productivities of itaconic acid and final yields were documented by transformants in respect to the parental strain. On the other hand, growth rate of all transformants remained suppressed which is due to the low initial pH value of the medium, one of the prerequisites for the accumulation of itaconic acid by A. terreus mycelium. © 2010 Springer-Verlag.

The activation, appropriation and practices of student-equity policy in Australian higher education

Current national reforms in Australian higher education have prioritised efforts to reduce educational disadvantage within a vernacular expression of neoliberal education policy. Student-equity policy in universities is enmeshed in a set of competitive student recruitment relations. This raises practice-based tensions as universities strive to meet specific institutional targets for low-socio-economic status (SES) and Indigenous student participation, whilst broadening participation more generally within the sector. This paper seeks empirically to trace the activation and appropriation of federal policy through two sites of higher education policy practices: a state government-sponsored equity practitioner body and two differently positioned universities, Dawson and McIllwraith, as they engage with low-SES schools. Working together Dorothy Smith’s insights into the textually mediated activation of local practices, Levinson and colleagues’ concept of the local appropriation of authorised policy, and Bourdieu’s notion of the contested field, we demonstrate that the generation of state level and institutionally specific policies for student-equity practices not only articulates to federal policy, but also appropriates the ruling relations of mandated policy. Further, the scope of these creative local appropriations is organised within a hierarchical academic field through which particular institutional imperatives, as well as the needs of low-SES students, are negotiated. The analysis demonstrates the vernacularisation of policy in the national rearticulation of global discourses, in appropriation at the level of the state body and in the practices of equity workers.

Atmospheric gas plasma–induced ROS production activates TNF-ASK1 pathway for the induction of melanoma cancer cell apoptosis

Atmospheric gas plasmas (AGPs) are able to selectively induce apoptosis in cancer cells, offering a promising alternative to conventional therapies that have unwanted side effects such as drug resistance and toxicity. However, the mechanism of AGP-induced cancer cell death is unknown. In this study, AGP is shown to up-regulate intracellular reactive oxygen species (ROS) levels and induce apoptosis in melanoma but not normal melanocyte cells. By screening genes involved in apoptosis, we identify tumor necrosis factor (TNF)-family members as the most differentially expressed cellular genes upon AGP treatment of melanoma cells. TNF receptor 1 (TNFR1) antagonist-neutralizing antibody specifically inhibits AGP-induced apoptosis signal, regulating apoptosis signal-regulating kinase 1 (ASK1) activity and subsequent ASK1-dependent apoptosis. Treatment of cells with intracellular ROS scavenger N-acetyl-l-cysteine also inhibits AGP-induced activation of ASK1, as well as apoptosis. Moreover, depletion of intracellular ASK1 reduces the level of AGP-induced oxidative stress and apoptosis. The evidence for TNF-signaling dependence of ASK1-mediated apoptosis suggests possible mechanisms for AGP activation and regulation of apoptosis-signaling pathways in tumor cells.

The large-scale production of graphene flakes using magnetically-enhanced arc discharge between carbon electrodes

A novel approach to large-scale production of high-quality graphene flakes in magnetically-enhanced arc discharges between carbon electrodes is reported. A non-uniform magnetic field is used to control the growth and deposition zones, where the Y-Ni catalyst experiences a transition to the ferromagnetic state, which in turn leads to the graphene deposition in a collection area. The quality of the produced material is characterized by the SEM, TEM, AFM, and Raman techniques. The proposed growth mechanism is supported by the nucleation and growth model.

The production of self-organized carbon connections between Ag nanoparticles using atmospheric microplasma synthesis

The formation of long self-organized carbon connections (where the length is much greater than the diameter) between Ag nanoparticles on a Si(1 0 0) surface in atmospheric pressure Ar + CH4 microplasmas is demonstrated. A growth scenario explaining the connection nucleation and growth is proposed, and this is supported by numerical simulations which reveal that the electric field pattern around the growing connections affects the surface diffusion of carbon adatoms, the main driving force for the observed self-organization. Results suggest that the microplasma-generated surface charges can be used as effective controls for the self-organized formation of complex carbon-based nano-networks for integrated nanodevices.

Tensions between policy and practice : reconciliation agendas in the Australian curriculum English

In various parts of the world, Indigenous and non-Indigenous peoples are actively working towards Reconciliation. In Australia, the context in which we each undertake our work as educationalists and researchers, the Reconciliation agenda has been pushed into schools and English teachers have been called on to share responsibility for facilitating the move towards a new national order. The recently introduced Australian Curriculum mandates that Aboriginal and Torres Strait Islander Histories and Cultures be embedded with “a strong” but “varying presence” into each learning area (Australian Curriculum, Assessment and Reporting Authority, 2013). In this paper we consider the tensions between policy and practice, when discourses external to education are recontextualised into the discipline of English. We do so by applying an analytical framework based on Bernstein’s (1990, 1996,2000) sociological theories about the structure of instructional and regulative discourses. Our findings suggest that the space to exert Reconciliatory agendas in the Australian Curriculum English is ambiguous and thus holds the potential to not only marginalise Indigenous knowledges but also to create tensions between policy and practice for non-Indigenous teachers of English.

Before and after the creative city : the politics of urban cultural policy in Austin, Texas

This article examines the politics and practice of urban cultural policy in Austin, Texas. I demonstrate how aspects of the local context frame how local government and cultural sector interests strive to initiate the direction of policy. While larger trends—such as Richard Florida's creative city thesis—influence cultural policy and planning, specific contextual factors including prior economic development and growth management policy, departmental organization, the forum for interaction between municipal actors and non-governmental coalitions, and the character of the city's cultural economy mediate such trends to produce policy outcomes. As this case shows, contemporary urban cultural policy is not simply due to the rise of the creative city discourse, but is an evolving product of past policy structures and shaped by local institutions and actors.
