A Ratiometric Fluorescent Metal Ion Indicator Based On Dansyl Labeled Poly(N-Isopropylacrylamide) Responds To A Quenching Metal Ion, Shawn Burdette, Jie Du, Shaojun Yao, W. Seitz, Nicholas Bencivenga, Justin Massing, Roy Planalp, Randy Jackson, Daniel Kennedy
Shawn C. Burdette
The fluorescence emission of poly(N-isopropylacrylamide) (PNIPAM) covalently tagged with a 5-(dimethylamino)naphthalene-1-sulfonyl (dansyl) fluorophore and an iminodiacetic acid (IDA) chelator changes with temperature and with Cu(II) complexation. Increasing the temperature above the lower critical solution temperature (LCST) causes the polymer to collapse from a coil to a compact globule. This changes the environment experienced by the fluorophore causing a shift in maximum emission wavelength from 546 to 508 nm and an increase in the ratio of emission intensity at 508 nm to emission intensity at 546 nm from 0.70 to almost 1.40. Metal ions can be sensed by working at a …
Recommendations For Australia’S Implementation Of The National Emergency Warning System Using Location-Based Services, Anas Aloudat, Katina Michael, Roba Abbas
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 …

Hatoko Comes Home: Civil Society And Nuclear Power In Japan, Daniel P. Aldrich, Martin Dusinberre
Hatoko Comes Home: Civil Society And Nuclear Power In Japan, Daniel P. Aldrich, Martin Dusinberre
Daniel P Aldrich
This article seeks to explain how, given Japan’s “nuclear allergy” following World War II, a small coastal town not far from Hiroshima volunteered to host a nuclear power plant in the early 1980s. Where standard explanations of conten- tious nuclear power siting decisions have focused on the regional power utilities and the central government, this paper instead examines the importance of historical change and civil society at a local level. Using a microhistorical approach based on interviews and archival materials, and framing our discussion with a popular Japanese television show known as Hatoko’s Sea, we illustrate the agency of municipal …

To Phd Or Not To Phd?, Daniel Edwards
Dr Daniel Edwards
Research degrees, particularly the PhD, are seen as an important stepping stone into a research career, particularly in the sciences where chemistry is no exception. However, as part of any contemplation about undertaking a PhD, prospective students should keep in mind the sort of career, types of future research and location of the work they might be hoping to pursue. A research project by the Australian Council for Educational Research (ACER) for the Federal Department of Education, Employment and Workplace Relations (DEEWR) provides some important insights into the supply and demand for research positions in science in Australia.

The Externalities Of Strong Social Capital: Post-Tsunami Recovery In Southeast India, Daniel P. Aldrich
The Externalities Of Strong Social Capital: Post-Tsunami Recovery In Southeast India, Daniel P. Aldrich
Daniel P Aldrich
Much research has implied that social capital functions as an unqualified “public good,” enhancing governance, economic performance, and quality of life (Coleman 1988; Cohen and Arato 1992; Putnam 1993; Cohen and Rogers 1995). Scholars of disaster (Nakagawa and Shaw 2004; Adger et al. 2005; Dynes 2005; Tatsuki 2008) have extended this concept to posit that social capital provides nonexcludable benefits to whole communities after major crises. Using qualitative methods to analyze data from villages in Tamil Nadu, India following the 2004 Indian Ocean tsunami, this paper demonstrates that high levels of social capital simultaneously provided strong benefits and equally strong …
High Speed Flight At Low Altitude: Hazard To Commercial Aviation ?, Paul F. Eschenfelder , Capt.
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
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. …
A World Without Work? [Review Of The Books The End Of Work And The Jobless Future], Lance A. Compa
A World Without Work? [Review Of The Books The End Of Work And The Jobless Future], Lance A. Compa
Lance A Compa
[Excerpt] These two books take different routes to the same conclusion: This Time It's For Real. The end of work is now upon us, and the jobless future beckons. This was portended in the past--by the development of steam-powered machinery, then electrical power, then by mid-twentieth century automation reflected in numerically-controlled machine tools, and even by the first and second generations of computers--but never realized as new outlets for employment took shape. Those days are done now. Advanced computers and software are bringing into being what Jeremy Rifkin calls a "near-workerless economy."
Media Evolution And Public Understanding Of Climate Science, Ann Williams
Media Evolution And Public Understanding Of Climate Science, Ann Williams
Ann E Williams
This paper employs public opinion data from a nationally representative probability sample to examine how information encounters and exposure to different media sources relate to individuals' beliefs about global warming. The analyses indicate that media source exposure (i.e., exposure to news and information about science presented through different media outlets), intentional information exposure (i.e., deliberate exposure to global warming news coverage), and inadvertent information exposure (i.e., unplanned exposure to news and information about science that is encountered online while searching for other forms of information) relate to beliefs about global warming, in significant and meaningful ways. Namely, the findings show …

The Use Of Environmental, Health And Safety Research In Nanotechnology Research, Jan Youtie, Alan Porter, Philip Shapira, Li Tang, Troy Benn
Li Tang
Environmental, health, and safety (EHS) concerns are receiving considerable attention in nanoscience and nanotechnology (nano) research and development (R&D). Policymakers and others have urged that research on nano's EHS implications be developed alongside scientific research in the nano domain rather than subsequent to applications. This concurrent perspective suggests the importance of early understanding and measurement of the diffusion of nano EHS research. The paper examines the diffusion of nano EHS publications, defined through a set of search terms, into the broader nano domain using a global nanotechnology R&D database developed at Georgia Tech. The results indicate that nano EHS research …

Charting Nano Environmental, Health, & Safety Research Trajectories: Is China Convergent With The United States?, Li Tang, Stephen Carley, Alan Porter
Li Tang
Despite China’s recent entrance into the Nano Environmental, Health, & Safety (“EHS”) field, China is currently the number two producer of Nano EHS research, following the United States. As is demonstrated in this paper, China is quickly gaining ground on the United States in a number of key Nano EHS research areas and looks to one day establish leadership positions of its own in these domains. China’s escalating efforts to promote Nano EHS research, along with its rapid growth of research outputs in this field and increasing Sino-U.S. research collaboration in multiple research domains, raises the question: Is Nano EHS …
Governing Nanotechnology For Solar Fuels: Towards A Jurisprudence Of Global Artificial Photosynthesis, Thomas A. Faunce
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
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
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 …

Japanese Liberal Democratic Party Support And The Gender Gap: A New Approach, Daniel P. Aldrich
Japanese Liberal Democratic Party Support And The Gender Gap: A New Approach, Daniel P. Aldrich
Daniel P Aldrich
Scholars have argued that there is a broad gender gap in support for the long-ruling Liberal Democratic Party (LDP) in Japan. We uncover strong evidence that age, rather than gender, along with rural or urban location, serves as the most critical determinant of party support. Through logistic regression, propensity score matching and simulation techniques applied to four large-scale datasets; we demonstrate that age effects are consistent but slowly diminishing across cohorts between the mid-1970s and the early 2000s. As Japanese women and men age, they come to support the LDP at similar rates controlling for education, income and other demographic …
