What Makes Hollywood Run? Capitalist Power, Risk and the Control of Social Creativity

This dissertation combines an interest in political economy, political theory and cinema to offer an answer about the pace of the Hollywood film business and its general modes of behaviour. More specifically, this dissertation seeks to find out how the largest Hollywood firms attempt to control social creativity such that the art of filmmaking and its related social relations under capitalism do not become financial risks in the pursuit of profit. Controlling the ways people make or watch films, the thesis argues, is an institutional facet of capitalist power. Capitalist powerthe ability to control, modify and, sometimes, limit social creation through the rights of ownershipis the foundation of capital accumulation. For the Hollywood film business, capitalist power is about the ability of business concerns to set the terms that mould the future of cinema. The overall objective of Part I is to outline and rectify some of the methodological problems that obscure our understanding of how capital is accumulated from culture. Marxism stands as the theoretical foil for this argument. Because Marxism defines capital such that only economic activity can create value, it needs to clearly distinguish between economics and politicsyet this is a distinction it is ultimately unable to make. With this backdrop in mind, Part I introduces the capital-as-power approach and uses it as a foundation to an alternative political economic theory of capitalism. The capital-as-power approach views capital not as an economic category, but as a category of power. Consequently, this approach reframes the accumulation of capital as a power process. Part II focuses on the Hollywood film business. It investigates how and to what extent major filmed entertainment attempts to accumulate capital by lowering its risk. The process of lowering risk has characterized Hollywoods orientation toward the social-historical character of cinema and mass culture. This push to lower risk has been most apparent since the 1980s. In recent decades, major filmed entertainment has used its oligopolistic control of distribution to institute an order of cinema based on several key strategies: saturation booking, blockbuster cinema and high-concept filmmaking

Modelling the flow behaviour of gas bubbles in a bubble column

Includes abstract.Includes bibliographical references (leaves 96-99).The bubble column reactor is commonly used in industry, although the fluid dynamics inside are not well understood. The challenges associated with solving multi phase flow problems arise from the complexity of the governing equations which have to be solved, which are typically mass, momentum and energy balances. These time-dependent problems need to include effects of turbulence and are computationally expensive when simulating the hydrodynamics of large bubble columns. In an attempt to reduce the computational expense in solving bubble column reactor models, a "cell" model is proposed which predicts the velocity flow field in the vicinity of a single spherical bubble. It is intended that this model would form the fundamental building block in a macroscale model framework that does predict the flow of multiple bubbles in the whole column. The non-linear Navier-Stokes (NVS) equations are used to model fluid flow around the bubble. This study focusses on the Reynolds number range where the linear Stokes equations can be used to accurately predict the flow around the bubble. The Stokes equations are mathematically easier to solve than the NVS equations and are thus less computationally expensive. The validity of the NVS model was tested against experimental data for the flow of water around a solid sphere and was found to be in close agreement for the Reynolds number range 25 to 80. The simulation results from the Stokes flow model were compared with those from the NVS flow model and were similar at Reynolds numbers below 1. The application is then in the partitioning of the bubble column into regions governed by either Stokes or NVS equations

European trade policy in agricultural products

Thirty years after the signing of the Treaty of Rome, the number of member States of the European Community has increased from six to twelve. In 1987, the Community is a more heterogeneous group than it was in 1957. The policies established to meet the needs of the 'original' six have to be adapted to meet the additional demands of the 'new' six.The process of adaptation is most evident in the Common Agricultural Policy (CAP), the policy which has been described as the 'motor of European integration'. The need to adapt the CAP arises from criticisms of the operation of the policy by some member States and the Community's taxpayers. However, these criticisms should not dictate the process of adaptation. The interests, social, economic, and political, which lie behind the CAP must also be considered. The Community Institutions, therefore, have a delicate balancing out to perform as they adapt the policy in the light of these diverse interests.One element which is missing from this balancing act is the demands of other countries. These countries are affected by the impact the CAP has on the international trading environment and the agricultural concessions they obtained by concluding agreements with the Community. The reason why these demands are not considered is that the Community does not have an explicitly formulated agricultural trade policy.The absence of this policy lessens the impact of a range of external Community policies and retards the full development of other internal policies. Through an analysis of the international trading environment, the association and development cooperation policies of the Community, this paper outlines the negative impact which the CAP has externally. To counter this, the paper develops a Common Agricultural Trade Policy which will allow the Community to, maintain the benefits of integration, enhance the development of other common policies and have a positive impact on agricultural trade and external policies. Just as the CAP has been described as the motor of integration, the common agricultural trade policy may be described as the vehicle for growth, internally and externally

Fluorescence imaging and modelling of virus structure and infection

Diseases caused by viruses represent a serious global health concern. In this thesis, I present novel methods for labelling, imaging and analysing virus particles. I also describe mathematical and computational models that can be used to describe biological structures, such as viruses. In studies of viral structure, pleomorphism, and articularly filamentous morphologies, are frequently overlooked.To characterise and better understand viral filaments, I developed and optimised an imaging protocol for individual virus particles that captured the heterogeneity of viral shape. I also produced analysis pipelines that took this image data to study the structure of viruses at the individual virion level in order to find an overall picture of the populations of virions that exist. These pipelines investigated virus size, patterning of surface proteins and the location of viral genome. I also demonstrated a novel virus labelling strategy that specifically labels virus that will aid in the future study of viral assembly and infection. I also used mathematical modelling to further understand the role of viral morphologies. I modelled virus particles as a pressure vessel to study engineering stress in relation to virus, bacteria, and cellular morphology. Together these advancements will further our ability to study viruses and our knowledge of virus structure

Promoting Creativity through Explicit Teaching Strategies

Creativity is a recognizable and valued skill but is prone to multiple interpretations both in terms of its very nature and how it can be developed in students. This paper highlights one approach that has been taken in an undergraduate unit in creativity that has involved the implementation of a staff development program in applying explicit teaching strategies. The approach integrates a conceptual model of teaching creativity with the application of a professional development program called Advancement via Individual Determination (AVID). The intervention was undertaken as part of an OLT grant in collaboration with Victoria University that explored the value of training teaching staff in explicit teaching strategies. Initial findings suggest that students responded well to the program and perceived value in terms of their engagement in learning and the development of their own creativity

HST imaging and Keck Spectroscopy of z~6 I-band Drop-Out Galaxies in the ACS GOODS Fields

We measure the surface density of i'-band dropout galaxies at z~6 through wide field HST/ACS imaging and ultra-deep Keck/DEIMOS spectroscopy. Using deep HST/ACS SDSS-i' (F775W) and SDSS-z' (F850LP) imaging from GOODS-N (200 arcmin^2), we identify 9 i'-drops satisfying an (i'-z')_AB>1.5 selection criterion to a depth of z'_AB=25.6 (corresponding to L*_UV at z~3-4). We use HK' imaging data to improve the fidelity of our sample, discriminating against lower redshift red galaxies and cool Galactic stars. Three i'-drops are consistent with M/L/T dwarf stars. We present ultra-deep Keck/DEIMOS spectroscopy of 10 objects from our combined GOODS-N and GOODS-S i'-drop sample. We detect Lyman-alpha emission at z=5.83 from one object in the GOODS-S field, which lies only 8arcmin away (i.e. 3Mpc/h_70) from the z=5.78 object already confirmed by Bunker et al. (2003). One possible Lyman-alpha emitter at z=6.24 is found in the GOODS-N field (although identification of this spatially-offset emission line is ambiguous). Using the rest-frame UV continuum from our 6 candidate z~6 galaxies from the GOODS-N field, we determine a lower limit to the unobscured volume-averaged global star formation rate at z~6 of (5.4+/-2.2)x10^-4 h_70 M_sun/yr/Mpc^3. We find that the cosmic star formation density in galaxies with unobscured star formation rates 15M_sun/yr/h_70^2 falls by a factor of 8 between z~3 and z~6. Hence the luminosity function of LBGs must evolve in this redshift interval: a constant integrated star formation density at $z>3$ requires a much steeper faint-end slope, or a brighter characteristic luminosity. This result is in agreement with our previous measurement from the Chandra Deep Field South (Stanway et al. 2003), indicating that cosmic variance is not a dominant source of uncertainty.Comment: to appear in ApJ; replaced with accepted versio

Dorsalization of the neural tube by the non-neural ectoderm

The patterning of cell types along the dorsoventral axis of the spinal cord requires a complex set of inductive signals. While the chordamesoderm is a well-known source of ventralizing signals, relatively little is known about the cues that induce dorsal cell types, including neural crest. Here, we demonstrate that juxtaposition of the non-neural and neural ectoderm is sufficient to induce the expression of dorsal markers, Wnt-1, Wnt-3a and Slug, as well as the formation of neural crest cells. In addition, the competence of neural plate to express Wnt-1 and Wnt-3a appears to be stage dependent, occurring only when neural tissue is taken from stage 8–10 embryos but not from stage 4 embryos, regardless of the age of the non-neural ectoderm. In contrast to the induction of Wnt gene expression, neural crest cell formation and Slug expression can be induced when either stage 4 or stage 8–10 neural plates are placed in contact with the non-neural ectoderm. These data suggest that the non-neural ectoderm provides a signal (or signals) that specifies dorsal cell types within the neural tube, and that the response is dependent on the competence of the neural tissue

A star-forming galaxy at z= 5.78 in the Chandra Deep Field South

We report the discovery of a luminous z = 5.78 star-forming galaxy in the Chandra Deep Field South. This galaxy was selected as an ‘i-drop’ from the GOODS public survey imaging with the Hubble Space Telescope/Advanced Camera for Surveys (object 3 in the work of Stanway, Bunker & McMahon 2003). The large colour of (i′−z′)AB = 1.6 indicated a spectral break consistent with the Lyman α forest absorption shortward of Lyman α at z≈ 6. The galaxy is very compact (marginally resolved with ACS with a half-light radius of 0.08 arcsec, so rhl 5. Our spectroscopic redshift for this object confirms the validity of the i′-drop technique of Stanway et al. to select star-forming galaxies atz≈ 6

Near-Infrared Properties of I-Drop Galaxies in the Hubble Ultra Deep Field

We analyse near-infrared HST/NICMOS F110W (J) and F160W (H) band photometry of a sample of 27 i'-drop candidate z~6 galaxies in the central region of the HST/ACS Ultra Deep Field (HUDF). The infrared colours of the 20 objects not affected by near neighbours are consistent with a high redshift interpretation. This suggests that the low redshift contamination of this i'-drop sample is smaller than that observed at brighter magnitudes where values of 10-40% have been reported. The J-H colours are consistent with a slope flat in f_nu (f_lam \propto lam^{-2}), as would be expected for an unreddened starburst. There is, however, evidence for a marginally bluer spectral slope (f_lam propto lam^{-2.2) which is perhaps indicative of an extremely young starburst (~10 Myr old) or a top heavy initial mass function and little dust. The low levels of contamination, median photometric redshift of z~6.0 and blue spectral slope, inferred using the near-infrared data, supports the validity of the assumptions in our earlier work in estimating the star formation rates and, that the majority of the i-drop candidates galaxies lie at z~6.Comment: Replaced to match accepted versio

Holistic engineering design : a combined synchronous and asynchronous approach

To aid the creation and through-life support of large, complex engineering products, organizations are placing a greater emphasis on constructing complete and accurate records of design activities. Current documentary approaches are not sufficient to capture activities and decisions in their entirety and can lead to organizations revisiting and in some cases reworking design decisions in order to understand previous design episodes. Design activities are undertaken in a variety of modes; many of which are dichotomous, and thus each require separate documentary mechanisms to capture information in an efficient manner. It is possible to identify the modes of learning and transaction to describe whether an activity is aimed at increasing a level of understanding or whether it involves manipulating information to achieve a tangible task. The dichotomy of interest in this paper is that of synchronous and asynchronous working, where engineers may work alternately as part of a group or as individuals and where different forms of record are necessary to adequately capture the processes and rationale employed in each mode. This paper introduces complimentary approaches to achieving richer representations of design activities performed synchronously and asynchronously, and through the undertaking of a design based case study, highlights the benefit of each approach. The resulting records serve to provide a more complete depiction of activities undertaken, and provide positive direction for future co-development of the approaches
