Stories from beyond the frame dilemas and contradictions of photojournalism in a digitized and globalized world

To engage in the practice of photojournalism is to occupy a position of privilege, because the practice involves entering, albeit for a short while, the lives of others. But with this privilege comes the burden of representation. In this sense I believe that photojournalism is currently in crisis. This crisis concerns the decontextualization of the image in media outlets and the relegation of the photojournalist to the role of merely a hunter/gatherer rather than a storyteller. In other words, photojournalists have become alienated from the process of re-presentation of their own stories. To some extent it has always been thus.

Through the frame & beyond the gaze

In Fiction in the Age of Photography[i], Nancy Armstrong examines the impact of photography on the way in which the nineteenth century novelists represented society. In particular she asks 'But what do we make of the fact that the novel's turn to pictorialism coincided with the sudden ubiquity of photographic images in the culture at large? Why did pictures begin to speak louder than words?

Robustness in health research : do differences in health measures, techniques, and time frame matter?

Survey-based health research is in a boom phase following an increased amount of health spending in OECD countries and the interest in ageing. A general characteristic of survey-based health research is its diversity. Different studies are based on different health questions in different datasets; they use different statistical techniques; they differ in whether they approach health from an ordinal or cardinal perspective; and they differ in whether they measure short-term or long-term effects. The question in this paper is simple: do these differences matter for the findings? We investigate the effects of life-style choices (drinking, smoking, exercise) and income on six measures of health in the US Health and Retirement Study (HRS) between 1992 and 2002: (1) self-assessed general health status, (2) problems with undertaking daily tasks and chores, (3) mental health indicators, (4) BMI, (5) the presence of serious long-term health conditions, and (6) mortality. We compare ordinal models with cardinal models; we compare models with fixed effects to models without fixed-effects; and we compare short-term effects to long-term effects. We find considerable variation in the impact of different determinants on our chosen health outcome measures; we find that it matters whether ordinality or cardinality is assumed; we find substantial differences between estimates that account for fixed effects versus those that do not; and we find that short-run and long-run effects differ greatly. All this implies that health is an even more complicated notion than hitherto thought, defying generalizations from one measure to the others or one methodology to another.

(Post)colonial ambivalences : Christina Stead and Janet Frame

This thesis is an evaluative comparison of two significant writers, the Australian Christina Stead, and New Zealander Janet Frame. In a detailed analysis of the novels, the writerly ambivalences of each author are explored. Their writings are revealed to be creative of new possibilities for female (post)colonial agency.

Frame rate improvement for the VFX1 headset in virtual reality applications

Concentrates on reducing the processing time to enhance the visual component of the experience in virtual reality. Investigates the use of two co-processing cards, each with their own microprocessor providing parallel processing to the host computer. Concludes that the frame rates of a single computer running the virtual reality system could be improved by up to 35% by the use of parallel processing.

Applying King et al.'s taxonomy to frame the IS discipline's engagement in green IS discourse

This paper considers how the IS discipline can engage with discourse on the institutions and their interventions which influence and regulate green IS innovation. To consider possible responses, we apply King et al.’s (1994) taxonomy, based on Institutional Theory, to frame a research agenda to guide future exploration and debate on the interventions to facilitate green IS innovation. Through the application of the taxonomy, we derive several pertinent questions for the discipline to consider as part of this debate. We conclude that the IS discipline can, and indeed should, play a more prominent role both through traditional responses (e.g., descriptive studies of green IS methodologies, organisational best practice, maturity models, etc.), but also through more active engagement in the form of participation and advocacy in shaping future green policy and regulation.

The performing frame

This project explores the ways that creative practices—improvised movement, choreographed dance, and digital video—produce new knowledge about the sociability of public space. In other words, it uses various theoretical concepts and practical strategies to document and analyse the ways people inhabit and sometimes subvert public spaces — such as plazas, malls and piazzas — as part of their everyday experience. Drawing on concepts developed within the fields of performance theory, spatial history, cultural geography and social theory, the project will build a methodological toolbox for understanding the relationships between the diverse groups that use public spaces in Melbourne, Australia. This ‘toolbox’ will subsequently be used to understand analogous public spaces in other parts of the world to generate comparative data about spatial sociability. The research will enable an innovative way of mapping social, civic and political relations in space through a series of creative interventions, and will reveal the politics of everyday movement while exposing tensions between the spaces of public culture — those framed and legitimated by state institutions — and what Michael Warner calls ‘Counter-Publics.’ That is, those oppositional groups who actively seek to use public space in subversive or unauthorised ways.

This project documents a series of performative interventions designed to harness the untapped potential of various forms of street performance genres to function as tools that can produce new ways of understanding the politics of movement in public space. These ‘interventions’ will be generated through a series of practical performance and movement workshops that will draw on street theatre techniques, contact improvisation, Laban movement analysis and contemporary dance choreography. The project will focus on a series of dyadic relationships: self and other, inside and outside, centre and periphery that are relevant to human interaction in public space.
Street performers — musicians, acrobats, jugglers, magicians, mimes and so on — seek public spaces with high volumes of pedestrian traffic in order to maximise their ability to draw an audience and make a living. These performers who create temporary performance zones alter the flow and intensity of movement around them, thereby transforming the plazas, piazzas, town squares and subways favoured by buskers. Some of these performers interact with their audience more than others, and are potentially capable of telling us something about the politics of space. The practice of ‘shadowing’ the movements of passers-by is an increasingly popular form of public entertainment around the world.

Performance evaluation of multi-frame super-resolution algorithms

Multi-frame super-resolution algorithms aim to increase spatial resolution by fusing information from several low-resolution perspectives of a scene. While a wide array of super-resolution algorithms now exist, the comparative capability of these techniques in practical scenarios has not been adequately explored. In addition, a standard quantitative method for assessing the relative merit of super-resolution algorithms is required. This paper presents a comprehensive practical comparison of existing super-resolution techniques using a shared platform and 4 common greyscale reference images. In total, 13 different super-resolution algorithms are evaluated, and as accurate alignment is critical to the super-resolution process, 6 registration algorithms are also included in the analysis. Pixel-based visual information fidelity (VIFP) is selected from the 12 image quality metrics reviewed as the measure most suited to the appraisal of super-resolved images. Experimental results show that Bayesian super-resolution methods utilizing the simultaneous autoregressive (SAR) prior produce the highest quality images when combined with generalized stochastic Lucas-Kanade optical flow registration.

Improving gambling survey research using dual-frame sampling of landline and mobile phone numbers

Gambling prevalence studies are typically conducted within a single (landline) telephone sampling frame. This practice continues, despite emerging evidence that significant differences exist between landline and mobile (cell) phone only households. This study utilised a dual-frame (landline and mobile) telephone sampling methodology to cast light on the extent of differences across groups of respondents in respect to demographic, health, and gambling characteristics.

A total of 2,014 participants from across Australian states and territories ranging in age from 18 to 96 years participated. Interviews were conducted using computer assisted telephone interviewing technology where 1,012 respondents from the landline sampling frame and 1,002 from the mobile phone sampling frame completed a questionnaire about gambling and other health behaviours. Responses across the landline sampling frame, the mobile phone sampling frame, and the subset of the mobile phone sampling frame that possessed a mobile phone only (MPO) were contrasted.

The findings revealed that although respondents in the landline sample (62.7 %) did not significantly differ from respondents in the mobile phone sample (59.2 %) in gambling participation in the previous 12 months, they were significantly more likely to have gambled in the previous 12 months than the MPO sample (56.4 %). There were no significant differences in internet gambling participation over the previous 12 months in the landline sample (4.7 %), mobile phone sample (4.7 %) and the MPO sample (5.0 %). However, endorsement of lifetime problem gambling on the NODS-CLiP was significantly higher within the mobile sample (10.7 %) and the MPO sample (14.8 %) than the landline sample (6.6 %).

Our research supports previous findings that reliance on a traditional landline telephone sampling approach effectively excludes distinct subgroups of the population from being represented inresearch findings. Consequently, we suggest that research best practice necessitates the use of a dual- rame sampling methodology. Despite inherent logistical and cost issues, this approach  needs to become the norm in gambling survey research.
