This article compares YouTube and the National Film and Sound Archive (NFSA) as resources for television historians interested in viewing old Australian television programs. The author searched for seventeen important television programs, identified in a previous research project, to compare what was available in the two archives and how easy it was to find. The analysis focused on differences in curatorial practices of accessioning and cataloguing. NFSA is stronger in current affairs and older programs, while YouTube is stronger in game shows and lifestyle programs. YouTube is stronger than the NFSA on “human interest” material—births, marriages, and deaths. YouTube accessioning more strongly accords with popular histories of Australian television. Both NFSA and YouTube offer complete episodes of programs, while YouTube also offers many short clips of “moments.” YouTube has more surprising pieces of rare ephemera. YouTube cataloguing is more reliable than that of the NFSA, with fewer broken links. The YouTube metadata can be searched more intuitively. The NFSA generally provides more useful reference information about production and broadcast dates.

Chinese independent cinema has developed for more than twenty years. Two sorts of independent cinema exist in China. One is underground cinema, which is produced without official approvals and cannot be circulated in China, and the other are the films which are legally produced by small private film companies and circulated in the domestic film market. This sort of ‘within-system’ independent cinema has played a significant role in the development of Chinese cinema in terms of culture, economics and ideology. In contrast to the amount of comment on underground filmmaking in China, the significance of ‘within-system’ independent cinema has been underestimated by most scholars. This thesis is a study of how political management has determined the development of Chinese independent cinema and how Chinese independent cinema has developed during its various historical trajectories. This study takes media economics as the research approach, and its major methods utilise archive analysis and interviews. The thesis begins with a general review of the definition and business of American independent cinema. Then, after a literature review of Chinese independent cinema, it identifies significant gaps in previous studies and reviews issues of traditional definition and suggests a new definition. After several case studies on the changes in the most famous Chinese directors’ careers, the thesis shows that state studios and private film companies are two essential domestic backers for filmmaking in China. After that, the body of the thesis provides an examination of the development of ‘within-system’ independent cinema. Specifically, three factors: government intervention, the majors’ performance (state studios and, later, the conglomerates) and the market conduct of independent cinema at various points in their trajectories are studied. The key findings of the study are as follows: First, most scholars have overlooked the existence and the significance of within-system Chinese independent cinema. Drawing on an American definition of the independent sector, this thesis proposes a definition of the sector in China: namely, any film that has not been financed, produced, and/or distributed by majors. The thesis also notes important contradictions in applying this definition: i.e. film-making is still dependent on policies that frame industry development. The thesis recognises that major tensions apply to filmmaking in China, which significantly differentiates the Chinese independents from those in the US. Second, the development of Chinese independent cinema is the result the rise of the private sector and the decline of the state studio system. As state studios encountered difficulties the private sector moved forward; consequently the environment improved for independent cinema. Third, before 2003, the film industry in China had little commercialisation. The government controlled independent cinema by means of license and censorship. State studios produced main melody films and Hollywood attracted most of the audiences. Many independent filmmakers focused on commercial films, thus contributing to film commercialisation. Fourth, after 2003, the film industry became increasingly fragmented. The government created distribution and exhibition opportunities for main melody films; conglomerates collaborated with Hong Kong players; Hong Kong co-productions and Hollywood occupied the film market; and small private film companies produced main melody films in order to earn meagre profits. The original contribution of the thesis is to advance the study of Chinese independent cinema. The study suggests a reasonable and practical definition of Chinese independent cinema. It shows how the Chinese government authorities have implemented economic measures to gain ideological control in the film industry. Finally, this the first study on Chinese independent cinema applying a synthesis of economic, political and historical perspectives.

We both love and hate our journalists. They are perceived as sexy and glamorous on the one hand, despicable and sleazy on the other. Opinion polls regularly indicate that we experience a kind of cultural schizophrenia in our relationship to journalists and the news media: sometimes they are viewed as heroes, at other times villains. From Watergate to the fabrication scandals of the 2000s, journalists have risen and fallen in public esteem. In this book, leading journalism studies scholar Brian McNair explores how journalists have been represented through the prism of one of our key cultural forms, cinema. Drawing on the history of cinema since the 1930s, and with a focus on the period 1997-2008, McNair explores how journalists have been portrayed in film, and what these images tell us about the role of the journalist in liberal democratic societies. Separate chapters are devoted to the subject of female journalists in film, foreign correspondents, investigative reporters and other categories of news maker who have featured regularly in cinema. The book also discusses the representation of public relations professionals in film. Illustrated throughout and written in an accessible and lively style suitable for academic and lay readers alike, Journalists in Film will be essential reading for students and teachers of journalism, and for all those concerned about the role of the journalist in contemporary society, not least journalists themselves. An appendix contains mini-essays on every film about journalism released in the cinema between 1997 and 2008.

For almost a decade before Hollywood existed, French firm Pathe towered over the early film industry with estimates of its share of all films sold around the world varying between 50-70%. Pathe was the first global entertainment company. This paper analyses its rise to market leadership by applying a theoretical framework drawn from the business literature on causes of industry dominance, which provides insights into how firms acquire and maintain market dominance, and in this case the film industry. This paper uses evidence presented by film historians to argue that Pathe “fits” the expected theoretical model of a dominant firm because it had a marketing orientation, used an effective quality-based competitive strategy and possessed the six critical strategic marketing capabilities that business research shows enable the best performing firms to consistently outperform rivals

In November 2010, the world watched as 33 Chilean miners were rescued from the depths of the earth where they had been stranded since July. We were able to watch because the world’s news media were there, drawn by the human drama, the suspense, the spectacle. It was a great news story, ideally suited for the 24-hour news culture we live in today, and the globalised audience that consumes it. Nothing much happened for 68 of those 69 days, until that final 24 hours when the miners emerged. But we were transfixed, engrossed, immersed in the story.

This study of photocatalytic oxidation of phenol over titanium dioxide films presents a method for the evaluation of true reaction kinetics. A flat plate reactor was designed for the specific purpose of investigating the influence of various reaction parameters, specifically photocatalytic film thickness, solution flow rate (1–8 l min−1), phenol concentration (20, 40 and 80 ppm), and irradiation intensity (70.6, 57.9, 37.1and 20.4 W m−2), in order to further understand their impact on the reaction kinetics. Special attention was given to the mass transfer phenomena and the influence of film thickness. The kinetics of phenol degradation were investigated with different irradiation levels and initial pollutant concentration. Photocatalytic degradation experiments were performed to evaluate the influence of mass transfer on the reaction and, in addition, the benzoic acid method was applied for the evaluation of mass transfer coefficient. For this study the reactor was modelled as a batch-recycle reactor. A system of equations that accounts for irradiation, mass transfer and reaction rate was developed to describe the photocatalytic process, to fit the experimental data and to obtain kinetic parameters. The rate of phenol photocatalytic oxidation was described by a Langmuir–Hinshelwood type law that included competitive adsorption and degradation of phenol and its by-products. The by-products were modelled through their additive effect on the solution total organic carbon.

Low oxygen pressure (hypoxia) plays an important role in stimulating angiogenesis; there are, however, few studies to prepare hypoxia-mimicking tissue engineering scaffolds. Mesoporous bioactive glass (MBG) has been developed as scaffolds with excellent osteogenic properties for bone regeneration. Ionic cobalt (Co) is established as a chemical inducer of hypoxia-inducible factor (HIF)-1α, which induces hypoxia-like response. The aim of this study was to develop hypoxia-mimicking MBG scaffolds by incorporating ionic Co2+ into MBG scaffolds and investigate if the addition of Co2+ ions would induce a cellular hypoxic response in such a tissue engineering scaffold system. The composition, microstructure and mesopore properties (specific surface area, nano-pore volume and nano-pore distribution) of Co-containing MBG (Co-MBG) scaffolds were characterized and the cellular effects of Co on the proliferation, differentiation, vascular endothelial growth factor (VEGF) secretion, HIF-1α expression and bone-related gene expression of human bone marrow stromal cells (BMSCs) in MBG scaffolds were systematically investigated. The results showed that low amounts of Co (< 5%) incorporated into MBG scaffolds had no significant cytotoxicity and that their incorporation significantly enhanced VEGF protein secretion, HIF-1α expression, and bone-related gene expression in BMSCs, and also that the Co-MBG scaffolds support BMSC attachment and proliferation. The scaffolds maintain a well-ordered mesopore channel structure and high specific surface area and have the capacity to efficiently deliver antibiotics drugs; in fact, the sustained released of ampicillin by Co-MBG scaffolds gives them excellent anti-bacterial properties. Our results indicate that incorporating cobalt ions into MBG scaffolds is a viable option for preparing hypoxia-mimicking tissue engineering scaffolds and significantly enhanced hypoxia function. The hypoxia-mimicking MBG scaffolds have great potential for bone tissue engineering applications by combining enhanced angiogenesis with already existing osteogenic properties.

The corset, with its laces and stays, appears to the modern eyes little more than a stylish torture device. However, the corset enjoyed a reputation among the most fashionable women of the nineteenth century. Since small waists were the primary measure of corporeal beauty, corsets were nearly universal among Western women of the middle class upwards. Wearing a corset was also a marker of decency; only lower classes and women of dubious reputation did not wear corsets. From instrument of torture and symbol of submission to its appropriation by women as a marker of sexual liberation, the corset has gone under a sartorial and symbolic transformation remaining the most erotic element of women’s dress. This paper discusses the corset in two Australian films, Picnic at Hanging Rock (Peter Weir, 1974) and Moulin Rouge (Baz Luhrman, 2001), arguing that the corset provides a counterpoint in each film signifying the tension between beauty and respectability, on the one hand, and desire and transgression, on the other. We argue that the corset is the primary prop around which the narrative revolves as well as the key signifying hook for the audience. The fact that erotic motifs are so rare in Australian films makes the centrality of the corset in these films even more powerful as a discursive trope
