Daily Stock Market Movement From Oscillating Social Mood Factors, Cari Bourette Dec 2011

Daily Stock Market Movement From Oscillating Social Mood Factors, Cari Bourette

Cari Bourette

Since 2006, there has been ongoing research into the correlation of a set of oscillating mood factors and socioeconomic, geopolitical, and natural events with the goal of forecasting increased risks of destabilizing events. While promising results have been forthcoming, it has been difficult to present models that allowed those outside a small circle of specialists to participate. Between July 2007 and June 2010, weekly social mood projections, as published in monthly issues of MoodCompass, were used to develop a model to convert four oscillating mood factors into stock market expectations. This model was modified to generate signals of projected stock …


Designing Carbon Taxation Schemes For Automobiles: A Simulation Exercise For Germany, Adamos Adamou, Sofronis Clerides, Theodoros Zachariadis Dec 2011

Designing Carbon Taxation Schemes For Automobiles: A Simulation Exercise For Germany, Adamos Adamou, Sofronis Clerides, Theodoros Zachariadis

Theodoros Zachariadis

Vehicle taxation based on CO2 emissions is increasingly being adopted worldwide in order to shift consumer purchases to low-carbon cars, yet little is known about the effectiveness and overall economic impact of these schemes. We focus on feebate schemes, which impose a fee on high-carbon vehicles and give a rebate to purchasers of low-carbon automobiles. We estimate a discrete choice model of demand for automobiles in Germany and simulate the impact of alternative feebate schemes on emissions, consumer welfare, public revenues and firm profits. The analysis shows that a well-designed scheme can lead to emission reductions without reducing overall welfare.

The Impact Of ‘‘No Impact Man’’: Alternative Hedonism As Environmental Appeal, Jen Schneider, Glen Miller Dec 2011

The Impact Of ‘‘No Impact Man’’: Alternative Hedonism As Environmental Appeal, Jen Schneider, Glen Miller

Jen Schneider

As ‘‘No Impact Man,’’ writer Colin Beavan conducted a one-year experiment to determine whether he and his family could reduce their environmental impact to zero while living and working in Manhattan. This article examines the No Impact Man (NIM) experiment both as ‘‘alternative hedonism,’’ a reconceptualization of the ‘‘good life’’ that avoids unduly damaging the natural world, and also as a kind of ‘‘eco-stunt,’’ an attempt to garner significant media coverage about positive environmental behaviors. We use DeLuca’s theorization of the ‘‘image event’’ to analyze the No Impact Man franchise—blog, book, and documentary film—though we modify that theory in order …

The Impact Of Driving Conditions On Phev Battery Performance, Nathan Christensen, John Patten, Steven Srivastava, Gary P. Nola Nov 2011

The Impact Of Driving Conditions On Phev Battery Performance, Nathan Christensen, John Patten, Steven Srivastava, Gary P. Nola

john a patten

The battery performance of a modified Prius with a 5 kWh plug-in battery was documented for a year to determine the impact of environmental conditions and user attributes on vehicle performance. Both fuel economy and pure electrical efficiency were compared to ambient temperature. The fuel economy has a positive relationship with ambient temperature until approximately 70˚F where the efficiency begins to drop. Electrical performance has a positive linear relationship with ambient temperature. With the emergence of electric vehicles (EVs) and PHEVs from a variety of automotive manufacturers, information on EV and PHEV performance for consumers will become more important.

Inequality, Communication And The Avoidance Of Disastrous Climate Change In A Public Goods Game, Alessandro Tavoni, Astrid Dannenberg, Giorgos Kallis, Andreas Loeschel Jul 2011

Inequality, Communication And The Avoidance Of Disastrous Climate Change In A Public Goods Game, Alessandro Tavoni, Astrid Dannenberg, Giorgos Kallis, Andreas Loeschel

Alessandro Tavoni

International efforts to provide global public goods often face the challenges of coordinating national contributions and distributing costs equitably in the face of uncertainty, inequality, and free-riding incentives. In an experimental setting, we distribute endowments unequally among a group of people who can reach a fixed target sum through successive money contributions, knowing that if they fail they will lose all their remaining money with 50% probability. In some treatments we give players the option to communicate intended contributions. We find that inequality reduces the prospects of reaching the target, but that communication increases success dramatically. Successful groups tend to …

Developing Criteria For Evaluating The Sustainability Of Emerging Energy, Kurt A. Rosentrater, Elif Kongar Apr 2011

Developing Criteria For Evaluating The Sustainability Of Emerging Energy, Kurt A. Rosentrater, Elif Kongar

Kurt A. Rosentrater

Over the last decade, the interest in and production of biofuels has grown rapidly. Renewable transportation fuels can be produced from a variety of substrates, using various processing strategies. Feedstock preference and factory scale are geographic dependent. However, it is important to understand the implications of deploying these types of systems on a large scale, both throughout the U.S. as well as globally. To assess the sustainability of various biofuel options, it is crucial to evaluate their performance according to a number of attributes. This has been done using Life Cycle Assessment (LCA). Even so, comparisons among biofuel options are …


Making The Human Dimensions Of Sustainable Community Development Visible To Engineers, Juan Lucena, Jen Schneider, Jon A. Leydens Mar 2011

Making The Human Dimensions Of Sustainable Community Development Visible To Engineers, Juan Lucena, Jen Schneider, Jon A. Leydens

Jen Schneider

Recently, engineers – particularly those working on sustainability-related initiatives – have increasingly turned their efforts towards under-served communities. This paper summarises the findings in Engineering and Sustainable Community Development (Juan Lucena et al., 2010) aimed at a diversity of these efforts which are grouped here under the term ‘engineering to help’. These initiatives often exist under names such as community service, humanitarian engineering, and engineers without borders or activities such as the Institution of Civil Engineers' co-sponsored workshop ‘Helping local communities to help themselves’. Although there has been a blossoming of engineering-to-help-related programmes around the world, there is a …

Conservation Genetics Of The Endangered Eastern Freshwater Cod, Maccullochella Ikei, Catherine Jane Nock Jan 2011

Conservation Genetics Of The Endangered Eastern Freshwater Cod, Maccullochella Ikei, Catherine Jane Nock

Dr Catherine J Nock

Fragmentation over evolutionary time scales following vicariant and dispersal events has long been recognised as a dominant process in biological diversification and speciation; while anthropogenic habitat fragmentation in recent times is considered a threat to the long-term persistence of species and ecosystems. The eastern freshwater cod Maccullochella ikei is Australia’s largest endangered freshwater fish species. Abundant in the Clarence and Richmond River systems at the time of European settlement, populations crashed in the early 1900s causing local extinctions and range reduction. Recovery efforts, including a prohibition on fishing for M. ikei and hatchery breeding programs, were initiated in an attempt …


Customer Response To Carbon Labelling Of Groceries, Jerome K. Vanclay, John Shortiss, Scott Aulsebrook, Angus M. Gillespie, Ben C. Howell, Rhoda Johanni, Michael J. Maher, Kelly M. Mitchell, Mark D. Stewart, Jim Yates Jan 2011

Customer Response To Carbon Labelling Of Groceries, Jerome K. Vanclay, John Shortiss, Scott Aulsebrook, Angus M. Gillespie, Ben C. Howell, Rhoda Johanni, Michael J. Maher, Kelly M. Mitchell, Mark D. Stewart, Jim Yates

Professor Jerome K Vanclay

Thirty-seven products were labelled to indicate embodied carbon emissions, and sales were recorded over a 3-month period. Green (below average), yellow (near average), and black (above average) footprints indicated carbon emissions embodied in groceries. The overall change in purchasing pattern was small, with black-labelled sales decreasing 6% and green-labelled sales increasing 4% after labelling. However, when green-labelled products were also the cheapest, the shift was more substantial, with a 20% switch from black- to green-label sales. These findings illustrate the potential for labelling to stimulate reductions in carbon emissions.

Strategic Environmental Assessment And Regional Infrastructure Planning: The Case Of York Region, Ontario, Denis Kirchhoff, Daniel D. Mccarthy, Debbe D. Crandall, Graham S. Whitelaw Jan 2011

Strategic Environmental Assessment And Regional Infrastructure Planning: The Case Of York Region, Ontario, Denis Kirchhoff, Daniel D. Mccarthy, Debbe D. Crandall, Graham S. Whitelaw

Denis Kirchhoff

Strategic environmental assessment (SEA) is seen as an instrument that is essential to realizing sustainability goals that transcend project-level undertakings (e.g. policies, plans and programmes). The purpose of this case-based, collaborative research was to extend practical and theoretical understanding of SEA to the related, but in practice poorly coordinated, processes of project-level environmental assessment (EA), master planning and regional land use planning. Semi-structured key informant interviews and review of policy documents were used as the main sources of qualitative data to explore the key events that have led to an emerging strategic approach to planning and EA in York Region. …

Influence Of Energy Policy On The Rate Of Implementation Of Biogas Power Plants In Germany During The 2001-2010 Decade, Izabela Chasiak, Wojciech M. Budzianowski Jan 2011

Influence Of Energy Policy On The Rate Of Implementation Of Biogas Power Plants In Germany During The 2001-2010 Decade, Izabela Chasiak, Wojciech M. Budzianowski

Wojciech Budzianowski

The current article describes energy policy tools, which caused intensive development of biogas-based power generation in Germany during the 2001-2010 decade. The German system of financial support to biogas power plants is presented in details. It is shown that in Germany, i.e. in a country characterised by similar climate and potentials to renewable energy to Poland, biogas power plants cover 10,7% of electricity demands in 2010, while all renewable energy sources cover only 5,4% of electricity demands. It is emphasised that under favourable Polish energy policy, the development of biogas energy can be very rapid.

A Meta-Analysis Of Global Urban Land Expansion, Karen C. Seto, Michail Fragkias, Burak Güneralp, Michael K. Reilly

Michail Fragkias

The conversion of Earth's land surface to urban uses is one of the most irreversible human impacts on the global biosphere. It drives the loss of farmland, affects local climate, fragments habitats, and threatens biodiversity. Here we present a meta-analysis of 326 studies that have used remotely sensed images to map urban land conversion. We report a worldwide observed increase in urban land area of 58,000 km2 from 1970 to 2000. India, China, and Africa have experienced the highest rates of urban land expansion, and the largest change in total urban extent has occurred in North America. Across all regions …


Efficient Water Conservation In Agriculture For Growing Urban Water Demands In Jordan, Raed Al-Tabini, A.R. Octavio, A,W. Frank, R. Phillips Dec 2010

Efficient Water Conservation In Agriculture For Growing Urban Water Demands In Jordan, Raed Al-Tabini, A.R. Octavio, A,W. Frank, R. Phillips

Raed Al-Tabini

A significant challenge worldwide is to increase food supply to accommodate a population growing to 10 billion in the face of climate change. Per capita water supply in Jordan is among the world’s lowest. Despite this scarcity, three quarters of Jordan’s water use is consumed by irrigated agriculture, while producing low economic values at the margin compared to urban uses. However, irrigated agriculture supports Jordan’s food security, so its policymakers continue to examine measures to produce more crop‐per‐drop in irrigated agriculture to permit scarce water to meet growing urban demands. This paper examines economically efficient measures to conserve water in …

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 …
