Synthesis and characterization of soluble conducting polymers

Although conducting polymers have various potential applications, lack of solubility is an impediment in their direct application to material surfaces. Synthesis of alkyl pyrrole monomers and subsequent polymerization into soluble conducting polymers are aimed as alternatives to conventional methods of application of conducting polymers on substrates. Alkyl chains are attached to a pyrrole ring to produce solubility in the resulting conducting polypyrroles, which allow direct application of conductive polymer emulsions to any desired surface. Friedel-Crafts acylation of the tosyl-protected pyrrole provides high yields of the 3-acylated product. The conductivity values of poly-3- and 3, 4-substituted pyrroles are generally less than the unmodified polypyrrole. Increasingly bulkier groups attached to the pyrrole means lower conductivity of the resultant polymer. As the carbon chain length attached to the 3-position of pyrrole increases, the solubility also increases. However, the magnitude of change in conductivity of films and pellets of soluble conducting polypyrroles over the alkyl range is not significant.

Supergirl scorned : lessons about young femininity in an Australian television satire

In this paper I explore the popular Australian television character of Ja’mie King – a teenage private school girl created and performed by male comedian Chris Lilley. I conceptualise Lilley’s satire as a public pedagogy of young femininity. My reading of his satire responds to recent feminist scholarship around young femininities and ‘girl power’, which explores representations of young femininity in popular culture in Western nations. Drawing primarily on the 2005 television mockumentary We can be heroes, I explore how King can be read in terms of exaggerated ‘girl power’ subjectivity. I examine the relationships, fashioned through the character of King, between ‘sexuality’ and global citizenship activity. I consider the extent to which King’s character teaches that young women can ‘have it all’. I explore the extent to which her character teaches that they can be ‘beautiful’ and ‘brainy’, ‘self-determined’ and ‘sexy’ at the same time.

Study of shot length and motion as contributing factors to movie tempo

This work seeks to lay the framework of film grammar over the video to be analyzed. We use the shot attributes of motion and shot length to produce a novel continuous measure of one of the aesthetic elements of films, namely the movie tempo. We refer to our previous work detailing the study of this construct and its automatic derivation, and also demonstrating its usefulness as an expressive element and as a sound basis for higher semantic descriptions such as dramatic events and story elements. Initial assessment of tempo was performed in our study on the basis that the relative importance of both shot length and motion in formulating the tempo function was the same. In this paper, we analyze their relative contributions to tempo, and demonstrate how these two factors can be manipulated to influence audience perception of movie time.

Racialized urban America and Holocaust film : negotiating the limits of representation

Sidney Lumet’s influential film The Pawnbroker (1964) is one of the earliest films to consider the encounter between Holocaust narratives and low-income, urban American racial minorities. As much concerned with contemporary ‘race relations’ in the United States as it is with the Nazis’ persecution of Europe’s Jews, the film intertwines the story of Holocaust survivor Sol Nazerman with the social tensions of 1960s America, represented in his relationship with the young Puerto Rican shop assistant Jesus Oritz. The film stylistically juxtaposes raw footage of concentration camp existence with dismal images of New York slum life. Against these backdrops, the protagonist’s climactic ‘silent scream’ emblematically merges the repressed trauma of the survivor with the filmmaker’s interest in race relations, a theme that has undergone various transformations in a number of films since. One film that contemporizes this encounter is Richard LaGravenese’s Freedom Writers (2007). As opposed to the tragic outcome of the pawnbroker’s induction into urban America, here the Holocaust is a redemptive tool that permits inner-city Black and Latino youth to contextualize their own suffering. After reading The Diary of Anne Frank, this group of ‘at-risk’ sophomores to inspired to collaborate on an ultimately successful effort to bring Miep Geis, the woman who sheltered Anne Frank, to speak at their high school. Foregrounded by the 1992 Los Angeles riots, gentiles teacher Erin Gruwell and savior Miep Geis transform the Holocaust from an amplified parallel of American slums into an event that permits the children of American postcoloniality to triumph in spite of their socio-economic circumstances. Underlining the tension between the Jewish specificity and unprecedented nature of the Holocaust, and the need to generate Holocaust narratives that intersect with intrinsically racialized American narratives, such films have significant implications for how collective memories of suffering are constructed and contested.

Film, representation and the exclusion of Aboriginal identity: examples from Australian cinema

Throughout the latter half of the past century cinema has played a significant role in the shaping of the core narratives of Australia. Films express and implicitly shape national images and symbolic representations of cultural fictions in which ideas about Indigenous identity have been embedded. In this paper, exclusionary practices in Australian narratives are analysed through examples of films representing Aboriginal identity. Through these filmic narratives the articulation, interrogation, and contestation of views about filmic representations of Aboriginal identity in Australia is illuminated. The various themes in the filmic narratives are examined in order to compare and contrast the ways in which the films display the operation of narrative closure and dualisms within the film texts.

Screen media, parenting practices, and the family environment in Australia: a longitudinal study of young children’s media use, lifestyles, and outcomes for healthy weight

Few studies of media use and adiposity explore the influence of parenting on children’s lifestyle behaviors. Screen media access, bedroom television, lack of physical activity, and snacking on energy-dense foods have long been implicated in child overweight. This research used data from the first three waves of the Longitudinal Study of Australian Children to investigate, prospectively, the associations between parental practices in early to middle childhood and children’s behaviors and weight in late childhood. A path model was used to investigate whether consistent parentingpredicted setting of boundaries for access to and use of media, and was indirectly associated with children’s lifestyle behaviors that increase the likelihood of healthy weight maintenance. The findings demonstrated that children’s lifestyles pertinent to weight maintenance and media use cluster together and involve both old and newer screen media, but are also predicted by parenting practices and the family environment.

D.A. Pennebaker: Interviews

This wide-ranging and insightful collection of interviews with D. A. Pennebaker (b. 1925) spans the prolific career of this pioneer of observational cinema. From the 1950s to the present day, D. A. Pennebaker has made documentary films that have revealed the world of politics, celebrity culture, and the music industry. Following his early collaborations with Robert Drew on a number of works for television, his feature-length portrait of Bob Dylan on tour in England in 1965 (the landmark film Dont Look Back) established so-called direct cinema as a form capable of achieving broad theatrical release. With Monterey Pop, Pennebaker inaugurated the popular mode of rock concert film (or "rockumentary"), a style of filmmaking he has expanded on through a number of films, including Ziggy Stardust and the Spiders from Mars and Depeche Mode: 101. Pennebaker has always regarded collaboration as an integral part of his filmmaking methods. His long-running collaboration with Richard Leacock and subsequently his work with Chris Hegedus have enriched his approach and, in the process, have instituted collaboration as a working practice integral to American direct cinema. His other collaborations, in particular, with Jean-Luc Godard and Norman Mailer, resulted in innovative combinations of observational techniques and fictional aesthetics. Such films as The War Room, which was about the 1992 Democratic primaries and was nominated for an Academy Award, and the 2009 Kings of Pastry continue to explore the capacities of observational documentary. In 2012 Pennebaker was the first documentary filmmaker to be awarded an Academy Honorary Award by the Academy of Motion Picture Arts and Sciences.

Titanium dioxide nanotube films for electrochemical supercapacitors: Biocompatibility and operation in an electrolyte based on a physiological fluid

Growing interest in developing devices that can be implantable or wearable requires the identification of suitable materials for the components of these devices. Electrochemical supercapacitors are not the exception in this trend, and identifying electrode materials that can be not only suitable for the capacitive device but also biocompatible at the same time is important. In addition, it would be advantageous if physiological fluids could be used instead of more conventional (and often corrosive) electrolytes for implantable or wearable supercapacitors. In this study, we assess the biocompatibility of films of anodized TiO2 nanotubes subjected to the subsequent annealing in Ar atmosphere and evaluate their capacitive performance in a physiological liquid. A biocompatibility test tracking cell proliferation on TiO2 nanotube electrodes and electrochemical tests in 0.01 M phosphate-buffered saline solution are discussed. It is expected that the study will stimulate further developments in this area.

Abstract & experimental animation – A century of innovation

This compact history of 100 years of abstract and experimental animation in Australia spans the earliest cameraless classics through to modern examples of what’s happening in the vibrant VJ scene. Australian animators and experimental filmmakers have been as innovative as anybody when it comes to creating abstract animation. This history is more elongated than many people believe, in part due to the inherent lack of commercial or popular screening opportunities for much of this sort of filmmaking. This program showcases a rich collection of films from this most elemental of all animation genres. It will be introduced by a small panel of filmmakers who will contextualise this history and explain its future.
