The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

The human brain has many subdivisions (�areas�) that are dedicated to vision, but in many cases their functions remain unclear. This project will study an area located deep in the brain, about which very little is known, and which appears to be affected from early stages in conditions such as Alzheimer�s disease. By understanding the patterns of electrical activity of cells in this region, and their connections with other brain areas, we hope to decipher their contribution to sensory cognition.
Improving Speech Perception Outcomes In Deaf Adults And Children Using Cochlear Implants

Summary
This project aims to further improve on speech understanding by deaf adults and children using the cochlear implant. In particular, we aim to individually modify the speech coding scheme on the basis of the basic hearing skills of the subject. In this manner, more speech information should be available and the users will likely gain more benefit from their cochlear implants.

In particular, we aim to individually modify the speech coding scheme on the basis of the basic hearing skills of the subject. In this manner, more speech information should be available and the users will likely gain more benefit from their cochlear implants. The speech processing strategy of the multiple-electrode cochlear implant, manufactured by the Australian biomedical company Cochlear Limited, codes acoustic frequency information on electrodes which are located in the cochlea. The assignment of frequencies to electrodes is consistent with the ordering of pitch in the cochlea. For optimum performance, all electrodes would need to be perceptually distinct from each other. Recent research with adults and children has shown that this is not the case for a number of subjects as adjacent electrodes sound the same. Thus important speech information may not be heard by these subjects. In this project, we will determine how well adults and children are able to hear differences between the electrodes, and then provide speech processing schemes which exclude those electrodes which sound the same as others in close proximity. The project will compare these modified strategies with the standard strategy currently used by the subjects over time, so that any differences in the way adults and children are able to improve on speech understanding will be determined. As far as can be determined, this project will be the first investigation to improve on speech understanding in children using the cochlear implant.Read moreRead less
Health Care Priorities: The Community's Preferences For Using Community Preferences

Summary
Determining how health care resources should be allocated - often termed rationing or priority setting - has traditionally been carried out by health care personnel, usually doctors but increasingly managers. More recently there has been a move to involve the general public in this process. Much of the research in this area has focussed on the methods used to elicit community preferences.

More recently there has been a move to involve the general public in this process. Much of the research in this area has focussed on the methods used to elicit community preferences. While this is an important area of investigation, a prior issue of how community members feel about the use of their preferences in informing health care priorities needs to be investigated. Four specific questions will be addressed in this study: (i) do members of the general public feel that, as individuals, they have a legitimate role to play in informing priority decisions in health care? if so why? if not, why not? (ii) does the nature-level-setting of the decisions for which priorities are to be set affect whether individual members of the public would wish to participate in the priority setting process? (e.g. different health services, medical procedures-treatments, diseases) (iii) whose preferences should be used if not the community's? (iv) faced ex post with the preferences of the community and the preferences (possibly different) of health service decision makers (i.e. Oexperts'), does this knowledge affect preferences for having community preferences count? A number of health authorities are currently looking for ways of engaging local communities in health care decision making. This study will indicate the appropriate levels at which community preferences are to be elicited and the type of decisions and settings in which they are most relevant.Read moreRead less
