The Value Of Government Mandated Location-Based Services In Emergencies In Australia, Anas Aloudat, Katina Michael, Roba Abbas, Mutaz M. Al-Debei Dec 2011

The Value Of Government Mandated Location-Based Services In Emergencies In Australia, Anas Aloudat, Katina Michael, Roba Abbas, Mutaz M. Al-Debei

Dr. Mutaz M. Al-Debei

The adoption of mobile technologies for emergency management has the capacity to save lives. In Australia in February 2009, the Victorian Bushfires claimed 173 lives, the worst peace-time disaster in the nation’s history. The Australian government responded swiftly to the tragedy by going to tender for mobile applications that could be used during emergencies, such as mobile alerts and location services. These applications, which are becoming increasingly accurate with the evolution of positioning techniques, have the ability to deliver personalized information direct to the citizen during crises, complementing traditional broadcasting mediums like television and radio. Indeed governments have a responsibility …


The Social And Behavioral Implications Of Location-Based Services, Katina Michael, M.G. Michael Nov 2011

The Social And Behavioral Implications Of Location-Based Services, Katina Michael, M.G. Michael

Associate Professor Katina Michael

The social and behavioral implications of location-based services (LBS) are only now beginning to come to light in advanced markets where the services have been adopted by just a little over half the market (Microsoft 2011). Depending on one’s definition of what constitutes location-based services, statistics on the level of adoption differ considerably. While it is helpful to provide as broad a list of applications as possible in what constitutes LBS (e.g. everything from in-vehicle navigation systems to downloading a map using a computer), it can also cloud the real picture forming behind this emerging technology. Emerging not in the …

Recommendations For Australia’S Implementation Of The National Emergency Warning System Using Location-Based Services, Anas Aloudat, Katina Michael, Roba Abbas

Professor Katina Michael

Mobile alerts, notifications and location-based emergency warning systems are now an established part of mobile government strategies in an increasing number of countries worldwide. In Australia the national emergency warning system (NEWS) was instituted after the tragic Black Saturday Victorian Bushfires of February 2009. In the first phase, NEWS has enabled the provision of public information from the government to the citizen during emergencies anywhere and any time. Moving on from traditional short message service (SMS) notifications and cell broadcasting to more advanced location-based services, this paper provides executive-level recommendations about the viability of location-based mobile phone services in NEWS …

High Speed Flight At Low Altitude: Hazard To Commercial Aviation ?, Paul F. Eschenfelder , Capt. Mar 2011

High Speed Flight At Low Altitude: Hazard To Commercial Aviation ?, Paul F. Eschenfelder , Capt.

Paul F. Eschenfelder

Commercial aircraft are capable of, and in fact, do, operate at high speed (>250 knots indicated airspeed [KIAS]) at low altitude (below 10,000’ above ground level) worldwide. Design, construction and certification standards for these aircraft were developed over 40 years ago. Since the development of these standards populations of large flocking birds have increased dramatically in many parts of the world. Yet neither design/construction standards nor operational practice have changed to reflect the new threat. Subsequent serious damage resulting from recent collisions indicates change is necessary. Since 2003, flight rules in Canada and the United States have been amended, …


Integrating Avian Radar Into The Aviation Operating Environment, Richard Sowden, Paul Eschenfelder Mar 2011

Integrating Avian Radar Into The Aviation Operating Environment, Richard Sowden, Paul Eschenfelder

Paul F. Eschenfelder

Avian radar technology has matured to the point where robust data and analysis tools are now able to provide the aviation industry with high quality information to support bird strike risk mitigation activities. The aviation operating environment is dynamic and challenging with complex interactions between the primary bird strike risk mitigation stakeholders; airport operators, air traffic service providers and flight crews. The transfer of this proof of concept technology into a suite of tools that is integrated into the aviation industry requires the engagement and support of the user community in the next critical evolutionary step of this emerging technology. …

Analyzing The Role Of Icts In The Tunisian And Egyptian Unrest From An Information Warfare Perspective, Brett Van Niekerk, Kiru Pillay, Manoj Maharaj Jan 2011

Analyzing The Role Of Icts In The Tunisian And Egyptian Unrest From An Information Warfare Perspective, Brett Van Niekerk, Kiru Pillay, Manoj Maharaj

Manoj Maharaj

In January 2011, the Tunisian government stepped down after weeks of protests; this was followed by unrest and protests in Egypt against the Egyptian government, leading also to the resignation of its president. Demonstrations in both countries were facilitated in some part by the online social media and related information and communications technologies that impacted the flow of information. The manner in which the information and communication technologies were employed suggests that the uprisings were a form of social information warfare. To provide an alternative understanding of the role of technology and information in the events that led to the …

Governing Nanotechnology For Solar Fuels: Towards A Jurisprudence Of Global Artificial Photosynthesis, Thomas A. Faunce Dec 2010

Governing Nanotechnology For Solar Fuels: Towards A Jurisprudence Of Global Artificial Photosynthesis, Thomas A. Faunce

Thomas A Faunce

The carbon-based fossil fuels (chiefly oil, coal, and natural gas) implicated in anthropogenic climate change are sequestered outcomes of millions of years of natural photosynthesis. Many emerging areas of nanotechnology research are focusing on artificial photosynthesis as a long-term planetary renewable energy and carbon management option – by providing an alternative form of energy to both fossil fuels and biofuels and as a means of stabilising atmospheric CO2. A macroscience Global Artificial Photosynthesis (GAP) Project, by allowing researchers to refine and enhance the process of photosynthesis, has the potential to become a valuable adjunct to or even supplant other bioenergy …


Artificial Photosynthesis: Feeding And Fuelling The Future, Thomas A. Faunce Dec 2010

Artificial Photosynthesis: Feeding And Fuelling The Future, Thomas A. Faunce

Thomas A Faunce

Large research teams in many nations are using nanotechnology to actively redesign photosynthetic components such as light capture antennae, artificial reaction centre proteins, organic polymers and inorganic catalysts. A major aim was to achieve low cost, localised, off-the electricity grid use of sunlight to split water and achieve hydrogen for fuel cells or compression and hyper-cooling to form a liquid fuel that when burnt produces fresh water. The first international conference dedicated to creating a Global Artificial Photosynthesis (GAP) project was held in Australia at Lord Howe Island on 14-18 August 2011. As well as having endorsement from the UNESCO …

Global Artificial Photosynthesis: A Scientific And Legal Introduction., Thomas A. Faunce

Thomas A Faunce

With the global human population set to exceed 10 billion by 2050, its collective energy consumption to rise from 400 to over 500 EJ/yr and with the natural environment under increasing pressure from these sources as well as from anthropogenic climate change, political solutions such as the creation of an efficient carbon price and trading scheme may arrive too late. In this context, the scientific community is exploring technological remedies. Central to these options is artificial photosynthesis – the creation, particularly through nanotechnology, of devices capable to doing what plants have done for millions of years – transforming sunlight, water …


Will International Trade Law Promote Or Inhibit Global Artificial Photosynthesis, Thomas A. Faunce Dec 2010

Will International Trade Law Promote Or Inhibit Global Artificial Photosynthesis, Thomas A. Faunce

Thomas A Faunce

Artificial photosynthesis (AP) is an area of well-advanced research involving large international groups at the cutting edge of synthetic biology and nanotechnology. In simple terms it offers to produce a cheap source of hydrogen for fuel through using sunlight to split water, as well as making basic starches by a process involving absorption of carbon dioxide via the enzyme RuBisCO. As the proliferating numbers of university-based research teams working in this area begin to combine, there will be a natural escalation of the expected time for a global roll-out of AP domestic and international devices. Policy attention will then turns …
