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.

Improving decision making in government service delivery using third party providers. This project focuses on analysing and improving decision making in government service delivery through two complementary parts: examining the range of models/potential models used by government agencies through 3rd party providers; and investigating how specific relations are managed/improved in selected industries (childcare, ageing, disability services). Our approaches encompass policy process theories, contr ....Improving decision making in government service delivery using third party providers. This project focuses on analysing and improving decision making in government service delivery through two complementary parts: examining the range of models/potential models used by government agencies through 3rd party providers; and investigating how specific relations are managed/improved in selected industries (childcare, ageing, disability services). Our approaches encompass policy process theories, contractual management, alternative service delivery, citizen empowerment theories, new institutional economics, industry impact analysis, and new modes of accountability. Analytical methods include survey and statistical investigations, comparative historical methods, case studies, comparative research with Canadian and NZ experts.Read moreRead less
Problems of identification and inference for 'non-standard' models in complex systems with special reference to finance and teletraffic. The project is concerned with 'non-standard' models needed to deal with complex systems, such as those exhibiting scaling and fractal properties. There is a focus on methods for dealing with heavy tailed distributions and long range dependent observations, for which most standard statistical methods break down, and on applications in finance and telecommunicati ....Problems of identification and inference for 'non-standard' models in complex systems with special reference to finance and teletraffic. The project is concerned with 'non-standard' models needed to deal with complex systems, such as those exhibiting scaling and fractal properties. There is a focus on methods for dealing with heavy tailed distributions and long range dependent observations, for which most standard statistical methods break down, and on applications in finance and telecommunications. An important part of the project concerns model validation for Heyde's fractal activity time geometric Brownian motion model, a candidate minimal description risky asset model to replace the geometric Brownian motion paradigm.Read moreRead less
Semantic Compliance in Complex Enterprise Information Systems. Large organisations have invested heavily to reduce the number of dependent information systems they support. Larger integrated systems should provide increased information reach and better coordination of activities. However there are major problems in practice - integration requires common meaning and context. Information-sharing within cooperating organisations is improved by enforcing compliance of databases with a master model. ....Semantic Compliance in Complex Enterprise Information Systems. Large organisations have invested heavily to reduce the number of dependent information systems they support. Larger integrated systems should provide increased information reach and better coordination of activities. However there are major problems in practice - integration requires common meaning and context. Information-sharing within cooperating organisations is improved by enforcing compliance of databases with a master model. Our research refines, extends and tests an approach for semantic compliance checking based on mathematical category theory. It investigates structures that help detect irregular data. The research uses models from NSW Health. Outcomes include improved processes and software for checking compliance and data anomalies.Read moreRead less
Investigations of the Integrity of the Australian Height Datum. The Australian Height Datum (AHD) forms the fundamental framework for all vertical spatial information in Australia. It supports a wide range of applications in areas such as geodesy, surveying, mapping, telecommunications, resource exploration and environmental science. This medium-term research programme will investigate the many issues surrounding the integrity of the AHD, and will rigorously redefine, correct and unify it with ....Investigations of the Integrity of the Australian Height Datum. The Australian Height Datum (AHD) forms the fundamental framework for all vertical spatial information in Australia. It supports a wide range of applications in areas such as geodesy, surveying, mapping, telecommunications, resource exploration and environmental science. This medium-term research programme will investigate the many issues surrounding the integrity of the AHD, and will rigorously redefine, correct and unify it within a global vertical framework. This will provide improved height information to the numerous users of the AHD in Australia, and allow Australia to contribute more fully to the global spatial data infrastructure.Read moreRead less
Theoretical and Model Strengthening of Future Global Navigation Satellite Systems (GNSS) to Yield Improved Geospatial Information for Tomorrow's Society. Australia is a significant user of Global Navigation Satellite Systems (GNSSs) because of its utility and for scientific applications (e.g., Earth-, atmospheric- and space-science). The national benefit of improved integer-estimation and model strengthening of integrated GNSSs is twofold: 1. all future scientific GNSS studies will rest on more ....Theoretical and Model Strengthening of Future Global Navigation Satellite Systems (GNSS) to Yield Improved Geospatial Information for Tomorrow's Society. Australia is a significant user of Global Navigation Satellite Systems (GNSSs) because of its utility and for scientific applications (e.g., Earth-, atmospheric- and space-science). The national benefit of improved integer-estimation and model strengthening of integrated GNSSs is twofold: 1. all future scientific GNSS studies will rest on more reliable positioning and related solutions, and 2. the refinements to these high-precision and high-integrity scientific GNSS applications will feed into much-improved geospatial information for tomorrow's society.

Invoking consistency of meaning in data integration and extraction for Electronic Health Records. Many governments want to implement an Electronic Health Record. Such a Record is a summary of events in an individual's medical history derived from diverse medical databases. Only some summaries are relevant to any medical condition. This project is to address these converse issues of data integration and extraction. Summaries must have variable structure according to event, and must be consistentl ....Invoking consistency of meaning in data integration and extraction for Electronic Health Records. Many governments want to implement an Electronic Health Record. Such a Record is a summary of events in an individual's medical history derived from diverse medical databases. Only some summaries are relevant to any medical condition. This project is to address these converse issues of data integration and extraction. Summaries must have variable structure according to event, and must be consistently drawn from datasets which have consistent meaning. We will extend a formal mathematical approach successfully developed for checking conformity of databases. NSW Health Department is partnering us, because the outcomes represent a step toward a practical Electronic Health Record.Read moreRead less
