Scenes, quarters and clusters : new experiments in the formation and governance of creative places in China

This thesis examines the formation and governance patterns of the social and spatial concentration of creative people and creative business in cities. It develops a typology for creative places, adding the terms 'scene' and 'quarter' to 'clusters', to fill in the literature gap of partial emphasis on the 'creative clusters' model as an organising mechanism for regional and urban policy. In this framework, a cluster is the gathering of firms with a core focus on economic benefits; a quarter is the urban milieu usually driven by a growth coalition consisting of local government, real estate agents and residential communities; and a scene is the spontaneous assembly of artists, performers and fans with distinct cultural forms. The framework is applied to China, specifically to Hangzhou – a second-tier city in central eastern China that is ambitious to become a 'national cultural and creative industries centre'. The thesis selects three cases – Ideal & Silian 166 Creative Industries Park, White-horse Lake Eco-creative City and LOFT49 Creative Industries Park – to represent scene, quarter and cluster respectively. Drawing on in-depth interviews with initiators, managers and creative professionals of these places, together with extensive documentary analysis, the thesis investigates the composition of actors, characteristics of the locality and the diversity of activities. The findings illustrate that, in China, planning and government intervention is the key to the governance of creative space; spontaneous development processes exist, but these need a more tolerant environment, a greater diversity of cultural forms and more time to develop. Moreover, the main business development model is still real estate based: this model needs to incorporate more mature business models and an enhanced IP protection system. The thesis makes a contribution to literature on economic and cultural geography, urban planning and creative industries theory. It advocates greater attention to self-management, collaborative governance mechanisms and business strategies for scenes, quarters and clusters. As intersections exist in the terms discussed, a mixed toolkit of the three models is required to advance the creative city discourse in China.

Discriminating stromatolite formation modes using rare earth element geochemistry: Trapping and binding versus in situ precipitation of stromatolites from the Neoproterozoic Bitter Springs Formation, Northern Territory, Australia

Stromatolites consist primarily of trapped and bound ambient sediment and/or authigenic mineral precipitates, but discrimination of the two constituents is difficult where stromatolites have a fine texture. We used laser ablation-inductively coupled plasma-mass spectrometry to measure trace element (rare earth element – REE, Y and Th) concentrations in both stromatolites (domical and branched) and closely associated particulate carbonate sediment in interspaces (spaces between columns or branches) from bioherms within the Neoproterozoic Bitter Springs Formation, central Australia. Our high resolution sampling allows discrimination of shale-normalised REE patterns between carbonate in stromatolites and immediately adjacent, fine-grained ambient particulate carbonate sediment from interspaces. Whereas all samples show similar negative La and Ce anomalies, positive Gd anomalies and chondritic Y/Ho ratios, the stromatolites and non-stromatolite sediment are distinguishable on the basis of consistently elevated light REEs (LREEs) in the stromatolitic laminae and relatively depleted LREEs in the particulate sediment samples. Additionally, concentrations of the lithophile element Th are higher in ambient sediment samples than in stromatolites, consistent with accumulation of some fine siliciclastic detrital material in the ambient sediment but a near absence in the stromatolites. These findings are consistent with the stromatolites consisting dominantly of in situ carbonate precipitates rather than trapped and bound ambient sediment. Hence, high resolution trace element (REE + Y, Th) geochemistry can discriminate fine-grained carbonates in these stromatolites from coeval non-stromatolitic carbonate sediment and demonstrates that the sampled stromatolites formed primarily from in situ precipitation, presumably within microbial mats/biofilms, rather than by trapping and binding of ambient sediment. Identification of the source of fine carbonate in stromatolites is significant, because if it is not too heavily contaminated by trapped ambient sediment, it may contain geochemical biosignatures and/or direct evidence of the local water chemistry in which the precipitates formed.

Computational fluid dynamic analysis of intracranial aneurysm bleb Formation (NS26P)

Purpose: The management of unruptured aneurysms remains controversial as treatment infers potential significant risk to the currently well patient. The decision to treat is based upon aneurysm location, size and abnormal morphology (e.g. bleb formation). A method to predict bleb formation would thus help stratify patient treatment. Our study aims to investigate possible associations between intra-aneurysmal flow dynamics and bleb formation within intracranial aneurysms. Competing theories on aetiology appear in the literature. Our purpose is to further clarify this issue. Methodology: We recruited data from 3D rotational angiograms (3DRA) of 30 patients with cerebral aneurysms and bleb formation. Models representing aneurysms pre-bleb formation were reconstructed by digitally removing the bleb, then computational fluid dynamics simulations were run on both pre and post bleb models. Pulsatile flow conditions and standard boundary conditions were imposed. Results: Aneurysmal flow structure, impingement regions, wall shear stress magnitude and gradients were produced for all models. Correlation of these parameters with bleb formation was sought. Certain CFD parameters show significant inter patient variability, making statistically significant correlation difficult on the partial data subset obtained currently. Conclusion: CFD models are readily producible from 3DRA data. Preliminary results indicate bleb formation appears to be related to regions of high wall shear stress and direct impingement regions of the aneurysm wall.

Canadian Charity Tribunal : a proposal for implementation

This paper is our attempt to focus the ongoing debate in Canada about the federal regulation of charities. More precisely, the paper examines the desirability of having an independent federal body assume some of the key roles which Revenue Canada currently plays in the charity field, as well as offering ideas about that body’s structure and operations.

The 1998 tax reform proposal fringe benefits tax and nonprofit organisations

Fringe Benefits Tax (FBT) is a tax payable by employers on the value of certain fringe benefits that have been provided to their employees or to associates of those employees. It was introduced on 1 July 1986 to improve the equity of the taxation system because non-salary and wage benefits were escaping the taxation base. FBT ensures that tax is paid on those fringe benefits provided in place of, or in addition to, salary or wages of employees.

Observation of new particle formation in subtropical urban environment

The aim of this study was to characterise the new particle formation events in a subtropical urban environment in the southern hemisphere. The study measured the number concentration of particles and its size distribution in Brisbane, Australia during 2009. The variation of particle number concentration and nucleation burst events were characterised as well as the particle growth rate which was first reported in urban environment of Australia. The annual average NUFP, NAitken and NNuc were 9.3 x 103, 3.7 x 103 and 5.6 x 103 cm-3, respectively. Weak seasonal variation in number concentration was observed. Local traffic exhaust emissions were a major contributor of the pollution (NUFP) observed in morning which was dominated by the Aitken mode particles, while particles formed by secondary formation processes contributed to the particle number concentration during afternoon. Overall, 65 nucleation burst events were identified during the study period. Nucleation burst events were classified into two groups, with and without particles growth after the burst of nucleation mode particles observed. The average particle growth rate of the nucleation events was 4.6 nm hr-1 (ranged from 1.79 – 7.78 nm hr-1). Case studies of the nucleation burst events were characterised including i) the nucleation burst with particle growth which is associated with the particle precursor emitted from local traffic exhaust emission, ii) the nucleation burst without particle growth which is due to the transport of industrial emissions from the coast to Brisbane city or other possible sources with unfavourable conditions which suppressed particle growth and iii) interplay between the above two cases which demonstrated the impact of the vehicle and industrial emissions on the variation of particle number concentration and its size distribution during the same day.

Battling in a virtual world: a proposal for increased copyright protection of multimedia products in Australia

This article discusses the adequacy of copyright protection afforded to multimedia products pursuant to the Copyright Act 1968 (Cth) and in response to international obligations. The paper critically evaluates the effect that the most recent amendments to the Copyright Act have had on the protection of copyright in multimedia products. An outline of some practical measures of protection available to copyright owners as alternatives or complements to the current statutory regime is provided, ultimately concluding that the current legislative protection is ineffective. The paper closes by considering possible future reform by way of statutory amendments to the Copyright Act aimed at increasing protection of copyright in multimedia products.

Scenes, quarters and clusters: The formation and governance of creative places in urban China

This paper presents a PhD program examining the formation and governance patterns of the social and spatial concentration of creative people and creative businesses in cities. It develops a typology for creative places, adding the terms ‘scene’ and ‘quarter’ to ‘clusters’, to fill in the literature gap of partial emphasis on the ‘creative clusters’ model as an organising mechanism for regional and urban policy. The framework is then applied to China, specifically to Hangzhou, a second-tier city in central eastern China that is ambitious to become a ‘national cultural and creative industries centre’. Drawing on in-depth interviews with initiators, managers and creative professionals from three cases selected respectively for scene, quarter and cluster, together with extensive documentary analysis, the paper investigates the composition of actors, characteristics of the locality and the diversity of activities of the three places. The findings demonstrate a convergence of the three terms. Furthermore, in China, planning and government intervention is the key to the governance of creative places; spontaneous development processes exist, but these need a more tolerant environment, a greater diversity of cultural forms and more time to develop. Moreover, the main business development model is still real estate based: this model needs to incorporate more mature business models and an enhanced IP protection system. Finally, the business strategies need to be combined with a self-management model for the creative class, and a collaborative governance mechanism with other stakeholders such as government, real estate developers and education providers.

Mission drift or strategic shift? Group formation strategies within MEPs

Microenterprise development programs (MEPs) have been recognised as a valuable way to help the poor engage in micro-businesses (Green et al., 2006; Vargas, 2000), presenting a way out of poverty (Choudhury et al., 2008; Strier, 2010). Concerns have been raised however, that the benefits of MEPs often don’t reach the extremely poor (Jones et al., 2004; Midgley, 2008; Mosley and Hulme, 1998; Nawaz, 2010; Pritchett, 2006). Balancing reach of these programs with depth is a challenging task. Targeting as many poor people as possible often results in MEPs focusing on the upper or middle poor, overlooking the most challenging group. As such, MEPs have been criticised for mission drift – losing sight of the organisation’s core purpose; assisting those more likely to succeed.

A proposal to change existing virus species names to non-Latinized binomials

A proposal has been posted on the ICTV website (2011. 001aG. N. v1. binomial_sp_names) to replace virus species names by non-Latinized binomial names consisting of the current italicized species name with the terminal word "virus" replaced by the italicized and non-capitalized genus name to which the species belongs. If implemented, the current italicized species name Measles virus, for instance, would become Measles morbillivirus while the current virus name measles virus and its abbreviation MeV would remain unchanged. The rationale for the proposed change is presented. © 2010 Springer-Verlag.

Pore formation during dehydration of polycrystalline gypsum observed and quantified in a time-series synchrotron radiation based X-ray micro-tomography experiment

We conducted an in-situ X-ray micro-computed tomography heating experiment at the Advanced Photon Source (USA) to dehydrate an unconfined 2.3 mm diameter cylinder of Volterra Gypsum. We used a purpose-built X-ray transparent furnace to heat the sample to 388 K for a total of 310 min to acquire a three-dimensional time-series tomography dataset comprising nine time steps. The voxel size of 2.2 μm3 proved sufficient to pinpoint reaction initiation and the organization of drainage architecture in space and time. We observed that dehydration commences across a narrow front, which propagates from the margins to the centre of the sample in more than four hours. The advance of this front can be fitted with a square-root function, implying that the initiation of the reaction in the sample can be described as a diffusion process. Novel parallelized computer codes allow quantifying the geometry of the porosity and the drainage architecture from the very large tomographic datasets (20483 voxels) in unprecedented detail. We determined position, volume, shape and orientation of each resolvable pore and tracked these properties over the duration of the experiment. We found that the pore-size distribution follows a power law. Pores tend to be anisotropic but rarely crack-shaped and have a preferred orientation, likely controlled by a pre-existing fabric in the sample. With on-going dehydration, pores coalesce into a single interconnected pore cluster that is connected to the surface of the sample cylinder and provides an effective drainage pathway. Our observations can be summarized in a model in which gypsum is stabilized by thermal expansion stresses and locally increased pore fluid pressures until the dehydration front approaches to within about 100 μm. Then, the internal stresses are released and dehydration happens efficiently, resulting in new pore space. Pressure release, the production of pores and the advance of the front are coupled in a feedback loop.

Hormone-dependent bacterial growth persistence and biofilm formation - A pilot study investigating human follicular fluid collected during IVF cycles

Human follicular fluid, considered sterile, is aspirated as part of an in vitro fertilization (IVF) cycle. However, it is easily contaminated by the trans-vaginal collection route and little information exists in its potential to support the growth of microorganisms. The objectives of this study were to determine whether human follicular fluid can support bacterial growth over time, whether the steroid hormones estradiol and progesterone (present at high levels within follicular fluid) contribute to the in vitro growth of bacterial species, and whether species isolated from follicular fluid form biofilms. We found that bacteria in follicular fluid could persist for at least 28 weeks in vitro and that the steroid hormones stimulated the growth of some bacterial species, specifically Lactobacillus spp., Bifidobacterium spp. Streptococcus spp. and E. coli. Several species, Lactobacillus spp., Propionibacterium spp., and Streptococcus spp., formed biofilms when incubated in native follicular fluids in vitro (18/24, 75%). We conclude that bacteria aspirated along with follicular fluid during IVF cycles demonstrate a persistent pattern of growth. This discovery is important since it can offer a new avenue for investigation in infertile couples.

Prosecutorial discretion in assisted dying in Canada : a proposal for charging guidelines

An Expert Panel of the Royal Society of Canada and a Select Committee of the Québec National Assembly both recently recommended the issuance of permissive guidelines for the exercise of prosecutorial discretion on voluntary euthanasia and assisted suicide and “medical aid in dying” respectively. It seems timely, therefore, to propose a set of offence-specific guidelines for how prosecutorial discretion should be exercised in cases of voluntary euthanasia and assisted suicide in Canadian provinces and territories. We take as our starting point the only existing guidelines of this sort currently in force in the world (i.e. the British Columbia Guidelines, and the England and Wales Guidelines). In light of certain concerns we have with these guidelines, we outline an approach to constructing guidelines for Canadian jurisdictions that begins with identifying three guiding principles we argue are appropriate for this purpose (respect for autonomy, the need for high-quality prosecutorial decision making, and the importance of public confidence in that decision making), and ends with a concrete and detailed set of proposed guidelines. The paper is consistent with, but also extends, the work of the Royal Society of Canada Expert Panel on End of Life Decision Making. Un panel d’expert de la Société Royale du Canada et une Commission spéciale de l’Assemblée nationale du Québec ont tous les deux récemment recommandé que soit émises des directives permettant exercice d’un pouvoir de poursuite discrétionnaire concernant l’euthanasie et le suicide assisté et « l’assistance médicale pour mourir », respectivement. Il semble donc à propos de proposer une série de directives spécifiques aux offenses sur la façon dont le pouvoir de poursuite discrétionnaire dans les territoires et provinces canadiennes serait appliqué dans les cas d’euthanasie et de suicide assisté. Nous avons pris comme point de départ les seules directives de la sorte existant déjà (c’est-à-dire celle de la Colombie-Britannique et de l’Angleterre et du Pays de Galles). Par contre, compte tenu de certaines de nos réserves concernant ces directives, nous avons ensuite établi les grandes lignes d’une approche permettant de mettre sur pied des directives pour les juridictions canadiennes, qui débute par l’identification de trois principes de base qui sont selon nous appropriées à cette fin (respect de l’autonomie, besoin pour une grande qualité de prise de prise de décision du poursuivant et la confiance du public envers cette prise de décision) pour se terminer par une série de directives concrètes et détaillées. Le présent document est compatible avec le travail de la Société royale du Canada tout en en augmentant la portée.
