Scheimpflug imaging of the post lens tear film during contact lens wear

A new imaging methodology is described to visualise the post lens tear film (PLTF) during contact lens wear. A rotating-Scheimpflug camera in combination with sodium fluorescein allows evaluation of the PLTF for different contact lens modalities, including mini-scleral, rigid gas permeable (RGP) and soft contact lenses. This imaging technique provides an extension of the instrument’s current functionality. The potential advantages and limitations of the technique are discussed.

Festival focus : Brisbane International Film Festival

In 2012, the Brisbane International Film Festival officially came of age, celebrating its twenty-first birthday. The festival has emerged from a tumultuous adolescence and redefined its position on the Australian festival circuit as an advocate of locally made films and documentary filmmaking in particular. Brisbane’s International Film Festival opened in 1992 and has since been attended by more than 400,000 filmgoers. The festival is held annually and showcases a diverse range of feature films, documentaries, short films, animation and experimental work, children’s films and retrospectives.

'It's Africa. It's Arizona. It's Antarctica. It's Afghanistan. Actually, it's Alberta' : Marketing locations to film producers

This chapter begins by outlining the dynamics of contemporary international film production and the inherent tension between ‘design interest’ and ‘location interest’. A history of the promotion of particular places as filmmaking locations (including Hollywood) is presented, prior to the establishment of the first film commissions. The creation of international associations and their role in professionalization, norm setting and the standardization of offerings and activities, is then described. The chapter concludes with a discussion of commissions’ work, the emergent discourse of ‘film friendliness,’ and the differences between location marketing and other kinds of destination marketing.

Sydney's media cluster: Continuity and change in film and television

A significant media city globally , Sydney is the production and design centre for the Australian media system and a subsidiary node of larger international systems principally headquartered in Los Angeles and London. Its media cluster is undergoing transformations to improve its position internationally by increasing capabilities and ties to other Australian and international production clusters. Sydney’s media cluster is a collection of suburbs forming an “arc” along major transport corridors stretching from Macquarie Park in the north to Sydney airport in the south. As a dispersed rather than tightly bound cluster, it is defined by the functional proximity provided by automobile and telecommunication networks Sydney’s media cluster is considered here along two dimensions—that of Sydney’s place within the ecology of Australian and international media and that of its internal organization within the geographical space of metropolitan Sydney. The first examines Sydney’s media cluster at the level of the metropolitan area of Sydney within its state, national and international contexts; while the second digs below this level to explore its working out in urban space.

The Down Under book and film remind us our copyright law’s still unfair for artists

Australian copyright law is broken, and the Australian Government isn’t moving quickly to fix it. Borrowing, quoting, and homage are fundamental to the creative process. This is how people are inspired to create. Under Australian law, though, most borrowing is copyright infringement, unless it is licensed or falls within particular, narrow categories. This year marks five years since the very real consequences of Australia’s restrictive copyright law for Australian artists were made clear in the controversial litigation over Men at Work’s 1981 hit Down Under. The band lost a court case in 2010 that found that the song’s iconic flute riff copied some of the 1934 children’s song Kookaburra Sits in the Old Gumtree. A new book and documentary tell us more about the story behind the anthem – and the court case. The book, Down Under by Trevor Conomy, and the documentary, You Better Take Cover by Harry Hayes, bring renewed interest and new perspectives on the tragic story.

Location and labor: Critical crossroads in global film and television

I approached the editorial prompt as an opportunity to work through some of the concerns driving my current research on creative labor in emergent or ‘peripheral’ media hubs, centers of production activity outside established media capitals that are nevertheless increasingly integrated into a global production apparatus. It builds from my research on the role that film, television and digital media production have played in the economic and cultural strategies of Glasgow, Scotland, and extends the focus on media work to other locations, including Prague and Budapest. I am particularly drawn to the spatial dynamics at play in these locations and how local producers, writers, directors and crew negotiate a sense of place and creative identity against the flows and counter-flows of capital and culture. This means not only asking questions about the growing ensemble of people, places, firms and policies that make international productions possible, but also studying the more quotidian relationships between media workers and the locations (both near and far) where they now find work. I do not see these tasks as unrelated. On the one hand, such queries underscore how international production depends on a growing constellation of interchangeable parts and is facilitated by various actors whose agendas may or may not converge. On the other hand, these questions also betray an even more complicated dynamic, a process that is shifting the spatial orientation of both location and labor around uneven and contested scales. As local industries reimagine themselves as global players, media practitioners are caught up in a new geography of creative labor: not only are personnel finding it increasingly necessary to hop from place to place to follow the work, but also place itself is changing, as locations morph into nebulous amalgamations of tax rebates, subsidized facilities, production services and (when it still matters) natural beauty.

Optimization of organic solar cells with thin film Au as anode

Optical transmittance and conductivity for thin metallic films, such as Au, are two inversely related and extremely important parameters for its application in organic photovoltaics as the front electrode. We report our findings on how these parameters have been optimized to attain maximum possible efficiencies by fabricating organic solar cells with thin Au film anodes of differing optical transmittances and consequently due to scaling at the nanolevel, varying electrical conductivities. There was an extraordinary improvement in the overall solar cell efficiency (to the order of 49%) when the Au thin film transmittance was increased from 38% to 54%. Surface morphologies of these thin films also have an effect on the critical parameters including, Voc, Jsc and FF.

Organic photovoltaics using thin gold film as an alternative anode to indium tin oxide

Indium Tin Oxide (ITO) is the most commonly used anode as a transparent electrode and more recently as an anode for organic photovoltaics (OPVs). However, there are significant drawbacks in using ITO which include high material costs, mechanical instability including brittleness and poor electrical properties which limit its use in low-cost flexible devices. We present initial results of poly(3-hexylthiophene): phenyl-C61-butyric acid methyl ester OPVs showing that an efficiency of 1.9% (short-circuit current 7.01 mA/cm2, open-circuit voltage 0.55 V, fill factor 0.49) can be attained using an ultra thin film of gold coated glass as the device anode. The initial I-V characteristics demonstrate that using high work function metals when the thin film is kept ultra thin can be used as a replacement to ITO due to their greater stability and better morphological control.

Stable organic photovoltaics using Ag thin film anodes

The interaction at the interface between a metal electrode and photoactive polymer is crucial for overall performance and stability of organic photovoltaics (OPVs). In this article, we report a comparative study of the stability of thin film Ag and indium tin oxide (ITO) as electrodes when used in conjunction with an interfacial PEDOT:PSS layer for P3HT:PCBM blend OPV devices. XPS measurements were taken for Ag and ITO/PEDOT:PSS layered samples with different exposure times to ambient conditions (∼25 °C, ∼50% relative humidity) to investigate the migration of Ag and In into the PEDOT:PSS layer. The change in efficiency of OPVs with a longer exposure time and degree of migration is explained by the analysis of XPS results. We propose the mechanism behind the interactions occurring at the interfaces. The efficiency of the ITO electrode OPVs continuously decreased to below 10% of the initial efficiency. However, the Ag devices displayed a slower degradation and maintained 50% of the initial efficiency for the same period of time.

Effects of metal ion concentration on electrodeposited CuZnSn film and its application in kesterite Cu2ZnSnS4solar cells

In this study, effects of concentrations of Cu(II), Zn(II) and Sn(II) ions in the electrolytic bath solution on the properties of electrochemically deposited CuZnSn (CZT) films were investigated. Study of the composition of a CZT film has shown that the metallic content (relative atomic ratio) in the film increased linearly with increase in the metal ion concentration. It is the first time that the relationship of the compositions of the alloy phases in the co-electrodeposited CZT film with the concentration of metal ions has been revealed. The results have confirmed that the formation and content of Cu6Sn5 and Cu5Zn8 alloy phases in the film were directly controlled by the concentration of Cu(II). SEM measurements have shown that Sn(II) has significant impact on film morphology, which became more porous as a result of the larger nucleation size of tin. The changes in the surface properties of the films was also confirmed by chronoamperometry characteristic (i–t) deposition curves. By optimization of metal ion concentrations in the electrolyte solution, a copper-poor and zinc-rich kesterite Cu2ZnSnS4 (CZTS) film was synthesized by the sulfurization of the deposited CZT film. The solar cell with the CZTS film showed an energy conversion efficiency of 2.15% under the illumination intensity of 100 mW cm 2.

Introduction to "International Perspectives on Business Innovation and Disruption in the Creative Industries Film, Video and Photography"

The creative industries are particularly fecund empirical fields for investigating the processes of business innovation and disruption. The creative industries are some of the fastest growing sectors in many economies (European Commission, 2001; OECD, 2006; United States Census Bureau, 2010) and thus are worthy of study in their own right. Additionally, the study of the creative industries affords insights into how we understand the current economic transformation towards knowledge- based economies more broadly. The transformation toward knowledge- based economies has been foreshadowed by the transformation of creative industries such as publishing, film, video, photography, music and so on...
