Summary
The ultimate goal of this project is to improve the ability of cochlear implant users to understand speech. The way in which a speech signal varies in amplitude over time provides useful information to the listener about the content of the speech signal. Currently, the way that the acoustic signal amplitude is converted to electrical signal amplitude for cochlear implantees does not take into consideration the very significant loudness summation present in multiple-electrode electrical stimulati ....The ultimate goal of this project is to improve the ability of cochlear implant users to understand speech. The way in which a speech signal varies in amplitude over time provides useful information to the listener about the content of the speech signal. Currently, the way that the acoustic signal amplitude is converted to electrical signal amplitude for cochlear implantees does not take into consideration the very significant loudness summation present in multiple-electrode electrical stimulation. That is, when there are multiple sequential current pulses on different electrodes over a short time, the resultant loudness is greater than the loudness due to individual current pulses. The lack of consideration of loudness summation effects has led to the amplitude variations in the acoustic signal not being accurately represented in the loudness variation perceived by the cochlear implantee. This project aims to develop a practical way of more accurately representing speech signal amplitude fluctuations for cochlear implantees by studying the effects of loudness summation. A second aim of the project is to study the effects on perception of using differently-shaped current pulses from those currently used. There is evidence from physiology experiments that using different shapes might cause the electrical stimulation to activate a more narrowly-spaced set of auditory neurons for each electrode. The application of results of both these studies will lead directly to improved perception of speech and other sounds by cochlear implantees, thus improving their communication ability and quality of life.Read moreRead less
Evaluating communication for development: supporting adaptive and accountable development. Australia spends $5.2 billion a year on overseas aid and is increasingly interested in the role of communication in sustainable development. This project will help to create a more effective means of understanding the impact of communication for development and improving its effectiveness in contributing to sustained, positive development outcomes.
Digital photography: mediation, memory and visual communication. This project aims to address the social impact of major shifts in the production, distribution, viewing and storage of photographic images which have profoundly altered their everyday use. By adopting an interdisciplinary, user-centred approach to digitally networked photography, the project will provide a more holistic understanding of how photographs mediate communication, sociality and memory in the present.

This project aims to address the social impact of major shifts in the production, distribution, viewing and storage of photographic images which have profoundly altered their everyday use. By adopting an interdisciplinary, user-centred approach to digitally networked photography, the project will provide a more holistic understanding of how photographs mediate communication, sociality and memory in the present. Expected outcomes include generating original empirical data, building international collaboration, and creating a new conceptual framework for assessing contemporary photographic practices. The research will provide community benefit by enabling insight into the social and ethical tensions affecting photography in the present.

Addressing the Crisis of Local Visual News in Regional and Remote Australia. This project aims to measure the volume and quality of visual content on regional news platforms by diverse publishers in eight key geographic areas. It is the first in Australia to examine the full cycle from production through presentation to consumption for local visual news in a regional context. Expected project outcomes include enhanced relationships between journalists and communities, stronger regional news ecos ....Addressing the Crisis of Local Visual News in Regional and Remote Australia. This project aims to measure the volume and quality of visual content on regional news platforms by diverse publishers in eight key geographic areas. It is the first in Australia to examine the full cycle from production through presentation to consumption for local visual news in a regional context. Expected project outcomes include enhanced relationships between journalists and communities, stronger regional news ecosystems, and a more representative local visual news product. These outcomes boost the academic understanding of an understudied area, help regional Australia, including regional Indigenous Australia, see itself in the journalism that is produced in the regions, and provide commercial benefits to hard-hit news providers.Read moreRead less

Social media influencers as conduits of knowledge in Australia and Asia. This project aims to evaluate how social media influencers can become conduits to communicate information among young people between Australia and East Asia. As icons on the internet who are experts in holding attention and amplifying content, influencers have expanded from being mere commercial enterprises to being conduits of public service information by reaching wide, diverse, and sometimes marginalised youth audiences ....Social media influencers as conduits of knowledge in Australia and Asia. This project aims to evaluate how social media influencers can become conduits to communicate information among young people between Australia and East Asia. As icons on the internet who are experts in holding attention and amplifying content, influencers have expanded from being mere commercial enterprises to being conduits of public service information by reaching wide, diverse, and sometimes marginalised youth audiences with important socio-cultural messages. This project will glean lessons from leading influencer ecologies in East Asia (Seoul, Shanghai and Tokyo), to understand how we can use internet-native communication formats to improve inter-cultural knowledge and relations in Australia.Read moreRead less
