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, …

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 …

Is Necessity The Mother Of Innovation? The Adoption And Use Of Web Technologies Among Congressional Offices, Kevin Esterling, David Lazer, Michael Neblo Nov 2010

Is Necessity The Mother Of Innovation? The Adoption And Use Of Web Technologies Among Congressional Offices, Kevin Esterling, David Lazer, Michael Neblo

David Lazer

From first paragraph: Communication between legislator and constituents is fundamental to effective democratic representation, and devising the institutional means for citizen/legislator communication stands as one of the core and persistent problems in the practice of democracy. A legislator needs information about the preferences, ideals, norms, and beliefs of her constituents in order to do her job well. Similarly, citizens need information about the actions and decisions of their representative in order to maintain appropriate accountability. But as national problems become more complex, and as the political process grows more and more dominated by experts and organized groups, it is becoming …

Nanotechnology And The International Law Of Weaponry: Towards International Regulation Of Nano-Weapons., Thomas A. Faunce, Hitoshi Nasu

Thomas A Faunce

The development of nanotechnology for military application is an emerging area of research and development, the pace and extent of which has not been fully anticipated by international legal regulation. Nano-weapons are referred to here as objects and devices using nanotechnology or causing effects in nano-scale that are designed or used for harming humans. Such weapons, despite their controversial human and environmental toxicity, are not comprehensively covered by specific, targeted regulation under international law. This article critically examines current international humanitarian law and arms control law regimes to determine whether significant gaps exist in the regulation of nanotechnology focused on …

Towards Self-Organizing, Smart Business Networks: Let’S Create ‘Life’ From Inert Information, David Bray, Benn Konsynski Nov 2008

Towards Self-Organizing, Smart Business Networks: Let’S Create ‘Life’ From Inert Information, David Bray, Benn Konsynski

David A. Bray

We review three different theories that can inform how researchers can determine the performance of smart business networks, to include: (1) the Theory of Evolution, (2) the Knowledge-Based Theory of the Firm, and (3) research insights into computers and cognition. We suggest that each of these theories demonstrate that to be generally perceived as smart, an organism needs to be self-organizing, communicative, and tool-making. Consequentially, to determine the performance of a smart business network, we suggest that researchers need to determine the degree to which it is self-organizing, communicative, and tool-making. We then relate these findings to the Internet and …

This special issue of Prometheus is dedicated to the theme of the Social Implications of National Security Measures on Citizens and Business. National security measures can be defined as those technical and non-technical measures that have been initiated as a means to curb breaches in national security, irrespective of whether these might occur by nationals or aliens in or from outside the sovereign state. National security includes such government priorities as maintaining border control, safeguarding against pandemic outbreaks, preventing acts of terror, and even discovering and eliminating identification fraud. Governments worldwide are beginning to implement information and communication security techniques …


Historical Lessons On Id Technology And The Consequences Of An Unchecked Trajectory, Katina Michael, M G. Michael May 2008

Historical Lessons On Id Technology And The Consequences Of An Unchecked Trajectory, Katina Michael, M G. Michael

M. G. Michael

This paper traces the use of identification techniques throughout the ages and focuses on the growing importance of citizen identification by governments. The paper uses a historical approach beginning with manual techniques such as tattoos, through to more recent automatic identification (auto-ID) techniques such as smart cards and biometrics. The findings indicate that identification techniques born for one purpose have gradually found their way into alternate applications, and in some instances have been misused altogether. There is also strong evidence to suggest that governments are moving away from localized identification schemes to more global systems based on universal lifetime identifiers.


Privacy, Value And Control Issues In Four Mobile Business Applications, Benjamin D. Renegar, Katina Michael, M G. Michael May 2008

Privacy, Value And Control Issues In Four Mobile Business Applications, Benjamin D. Renegar, Katina Michael, M G. Michael

M. G. Michael

This paper presents four case studies that explore the adoption and acceptance of mobile technologies and services within the context of the privacy-value-control (PVC) trichotomy. The technologies studied include: the mobile phone, electronic toll payment tags, e-passports, and loyalty card programs. The study shows that despite the potential barriers to adoption in each of the depicted cases, the applications were embraced with great success soon after their introduction. An understanding of why these mobile innovations succeeded in spite of the concerns surrounding them will serve to help practitioners understand other issues currently plaguing emerging technologies like radio-frequency identification (RFID) tags …
