  1. When we don't know the costs or the benefits: adaptive strategies for abating climate change

    Lempert, R.J.; Schlesinger, M.E.; Bankes, S.C.

    1996-01-01

    Most quantitative studies of climate-change policy attempt to predict the greenhouse-gas reduction plan that will have the optimum balance of long-term costs and benefits. The authors find that the large uncertainties associated with the climate-change problem can make the policy prescriptions of this traditional approach unreliable. In this study the authors construct a large uncertainty space that includes the possibility of large and/or abrupt climate changes and/or of technology breakthroughs that radically reduce projected abatement costs. Computational experiments are used on a linked system of climate and economic models to compare the performance of a simple adaptive strategy - one that can make midcourse corrections based on observations of the climate and economic systems - and two commonly advocated 'best-estimate' policies based on different expectations about the long-term consequences of climate change. It was found that the 'Do-a-Little' and 'Emissions-Stabilization' best-estimate policies perform well in the respective regions of the uncertainty space where their estimates are valid, but can fail severely in those regions where their estimates are wrong. In contrast, the adaptive strategy can make midcourse corrections and avoid significant errors. While its success is no surprise, the adaptive-strategy approach provides an analytic framework to examine important policy and research issues that will likely arise as society adapts to climate change, which cannot be easily addressed in studies using best-estimate approaches. 44 refs., 15 figs., 3 tabs

  2. Economic restructuring in Eastern Europe and acid rain abatement strategies

    Amann, Markus; Klaassen, Ger; Schoepp, Wolfgang; Soerensen, Lene; Hordijk, Leen

    1992-01-01

    Acid rain abatement strategies in Europe are currently being discussed in view of the expiration of the Helsinki Protocol on SO 2 emission reduction. The changing energy situation in Eastern European countries is expected to have an influence on the deposition pattern in Europe. The paper presents a consistent energy scenario for Eastern European countries and compares optimal strategies to reduce SO 2 emissions. These strategies are based on runs with the RAINS model in which environmental targets have been set based on critical loads for sulphur. The analysis shows that economic restructuring and efficiency improvements in Eastern European countries, as well as in Western Europe, may result in significantly lower sulphur abatement costs. Potential assistance to Eastern Europe to guarantee desired environmental standards in Western countries should therefore focus not only on providing emission control devices but also on the success of the economic transition process.

    Agriculture contributes significantly to the anthropogenic emissions of non-CO2 greenhouse gases methane and nitrous oxide. In this paper, a review is presented of the agriculture related sources of methane and nitrous oxide, and of the main strategies for mitigation. The rumen is the most important

  4. The value of international cooperation for abating global climate change

    Hammitt, James K.; Adams, John L.

    1996-01-01

    Because abatement of global climate change is a public good, independent national actions may not produce the efficient quantity. Using a numerical integrated-assessment model, abatement costs and damages induced by climate change are compared at the cooperative and noncooperative solutions to a set of two-party dynamic games between the industrialized and developing countries. Games with perfect and imperfect information about climate and economic factors are considered. Across 144 games with perfect information, incorporating different values of climate and economic parameters, the noncooperative solution usually yields global benefits comparable to those of the cooperative solution. In about one-fifth of these games, however, a second noncooperative solution exists which yields none of the benefits of the cooperative solution. In a game with imperfect information, where the state of nature is uncertain in the first but known in the second of two periods, the expected benefits of the noncooperative solution are 98% of the expected benefits of the cooperative solution. In contrast to single-agent studies which show little cost to delaying abatement, the benefits of cooperation are usually lost if cooperation is delayed 20 years

  5. Asia least-cost greenhouse gas abatement strategy identification and assessment of mitigation options for the energy sector

    Gupta, Sujata; Bhandari, Preety

    1998-01-01

    The focus of the presentation was on greenhouse gas mitigation options for the energy sector for India. Results from the Asia Least-cost Greenhouse gas Abatement Strategies (ALGAS) project were presented. The presentation comprised of a review of the sources of greenhouse gases, the optimisation model, ie the Markal model, used for determining the least-cost options, discussion of the results from the baseline and the abatement scenarios. The second half of the presentation focussed on a multi-criteria assessment of the abatement options using the Analytical Hierarchical Process (AHP) model. The emissions of all greenhouse gases, for India, are estimated to be 986.3 Tg of carbon dioxide equivalent for 1990. The energy sector accounted for 58 percent of the total emissions and over 90 percent of the CO2 emissions. Net emissions form land use change and forestry were zero. (au)

  6. Climate modelling with endogenous technical change: Stochastic learning and optimal greenhouse gas abatement in the PAGE2002 model

    Alberth, Stephan; Hope, Chris

    2007-01-01

    This paper looks at the impact of ETC on the costs and benefits of different abatement strategies using a modified version of the PAGE2002 model. It was found that for most standard abatement paths there would be an initial 'learning investment' required that would substantially reduce the unit costs of CO 2 abatement as compared to a business as usual scenario. Furthermore, optimising an abatement program where ETC has been included leads to an increase in cost uncertainty during the period of widespread CO 2 abatements due to our lack of knowledge of the learning investments involved. Finally, the inclusion of ETC leads to a slightly deferred optimised abatement path followed by a rapid abatement program. Together, the results draw attention to the possibilities of 'uncovering uncertainty' through proactive abatements. 'Learning about learning' could become an important consideration for any plan to optimise future abatements

  7. Optimal Coordination Strategy of Regional Vertical Emission Abatement Collaboration in a Low-Carbon Environment

    Daming You

    2018-02-01

    Full Text Available This study introduces a time factor into a low-carbon context, and supposes the contamination control state of local government and the ability of polluting enterprise to abate emissions as linear increasing functions in a regional low-carbon emission abatement cooperation chain. The local government effectuates and upholds the low-carbon development within the jurisdiction that is primarily seeking to transform regional economic development modes, while the polluting enterprise abates the amounts of emitted carbon in the entire period of product through simplifying production, facilitating decontamination, and adopting production technology, thus leading to less contamination. On that basis, we infer that the coordinated joint carbon reduction model and two decentralization contracts expound the dynamic coordination strategy for a regional cooperation chain in terms of vertical carbon abatement. Furthermore, feedback equilibrium strategies that are concerned with several diverse conditions are compared and analyzed. The main results show that a collaborative centralized contract is able to promote the regional low-carbon cooperation chain in order to achieve a win–win situation in both economic and environmental performance. Additionally, the optimal profits of the entire regional low-carbon cooperation channel under an integration scenario evidently outstrip that of two non-collaborative decentralization schemes. Eventually, the validity of the conclusions is verified with a case description and numerical simulation, and the sensitivity of the relevant parameters is analyzed in order to lay a theoretical foundation and thus facilitate the sustainable development of a regional low-carbon environment.

  8. Enforcement of Intellectual Property, Pollution Abatement, and Directed Technical Change

    Schaefer, Andreas

    2017-01-01

    We theoretically investigate the interaction between endogenous enforcement of intellectual property rights (IPRs) and tax-financed pollution abatement measures. IPRs affect dirty and clean intermediates alike such that higher IPR enforcement may promote the transition to the clean technology, if this technology is productive enough. If the green technology is relatively unproductive, higher IPRs promote the dirty technology while pollution is increasing. As households are due to subsistence ...

  9. Energy abatement in Chinese industry: Cost evaluation of regulation strategies and allocation alternatives

    Xia, X.H.; Chen, G.Q.

    2012-01-01

    For Chinese industry, the costs of different energy consumption abatement scenarios are evaluated by the method of directional distance function. These scenarios are based on the combinations of regulation strategies and allocation alternatives—the former are sectors and provinces, and the latter include the five principles of average, intensity share, absolute share, discriminatory absolute and discriminatory intensity. For all the scenarios, the quantitative impacts in terms of output potential loss are calculated and compared. Due to less output potential loss for all the allocation alternatives, the sector regulation strategy is shown to be more effective than the province regulation strategy. It is also demonstrated that, among all the scenarios considered, the sector regulation based on the intensity share principle and the province regulation based on the absolute share principle are the two optimal. The performances of energy abatement allocation of the 11th and 12th Five Year Plans of China are assessed against the simulated scenarios. - Highlights: ► The costs of different energy consumption abatement scenarios are evaluated for Chinese industry. ► The impacts on all entities under all allocation alternatives are calculated and compared. ► The optimal scenarios for the different strategies are identified. ► The performances of the 11th and 12th Five Year Plans are assessed.

  10. Pollution abatement from road transport: cross-sectoral implications, climate co-benefits and behavioural change

    Oxley, T.; Elshkaki, A.; Kwiatkowski, L.; Castillo, A.; Scarbrough, T.; ApSimon, H.

    2012-01-01

    With the abatement potential of end-of-pipe technologies for road transport becoming increasingly marginal, and with greater emissions reductions still needed in order to reduce pollution, alternative strategies involving behavioural change and choices between fossil fuelled or low carbon vehicles becomes more important. The environmental requirements include local air quality objectives, meeting national emissions ceilings to limit transboundary effects, and to aspire to significant reductions in greenhouse gas emissions. In this paper we use the BRUTAL sub-model of the UK integrated Assessment Model (UKIAM) to investigate a selection of alternative strategies including downsizing of cars, switching from petrol to diesel, and the introduction of electric, bio-fuelled or hydrogen vehicles into the fleet, relative to a business-as-usual projection for 2020. Projected impacts upon air quality limit values, national emissions ceilings and CO 2 emissions are assessed in relation to local, national and international objectives. We discuss related life-cycle impacts, implications for infrastructure, and potential impacts upon emissions from other sectors in order to highlight the full potential implications of the different strategies within the context of changes resulting from other policy developments at different scales.

  11. Effects of Local Greenhouse Gas Abatement Strategies on Air Pollutant Emissions and on Health in Kuopio, Finland

    Arja Asikainen

    2017-06-01

    Full Text Available Implementation of greenhouse gas (GHG abatement strategies often ends up as the responsibility of municipal action rather than national policies. Impacts of local GHG reduction measures were investigated in the EU FP7 funded project Urban Reduction of Greenhouse Gas Emissions in China and Europe (URGENCHE. Kuopio in Finland was one of the case study cities. The assessed reduction measures were (1 increased use of biomass in local heat and power cogeneration plant, (2 energy efficiency improvements of residences, (3 increased biofuel use in traffic, and (4 increased small scale combustion of wood for residential heating. Impact assessment compared the 2010 baseline with a 2020 BAU (business as usual scenario and a 2020 CO2 interventions scenario. Changes in emissions were assessed for CO2, particulate matter (PM2.5 and PM10, NOx, and SO2, and respective impacts were assessed for PM2.5 ambient concentrations and health effects. The assessed measures would reduce the local CO2 emissions in the Kuopio urban area by over 50% and local emissions of PM2.5 would clearly decrease. However, the annual average ambient PM2.5 concentration would decrease by just 4%. Thus, only marginal population level health benefits would be achieved with these assumed local CO2 abatement actions.

  12. Directed technical change and the adoption of CO2 abatement technology. The case of CO2 capture and storage

    Otto, Vincent M.; Reilly, John

    2008-01-01

    This paper studies the cost-effectiveness of combining traditional environmental policy, such as CO 2 -trading schemes, and technology policy that has aims of reducing the cost and speeding the adoption of CO 2 abatement technology. For this purpose, we develop a dynamic general equilibrium model that captures empirical links between CO 2 emissions associated with energy use, directed technical change and the economy. We specify CO 2 capture and storage (CCS) as a discrete CO 2 abatement technology. We find that combining CO 2 -trading schemes with an adoption subsidy is the most effective instrument to induce adoption of the CCS technology. Such a subsidy directly improves the competitiveness of the CCS technology by compensating for its markup over the cost of conventional electricity. Yet, introducing R and D subsidies throughout the entire economy leads to faster adoption of the CCS technology as well and in addition can be cost-effective in achieving the abatement target.

  13. Ammonia emissions from livestock industries in Canada: Feasibility of abatement strategies

    Carew, Richard

    2010-01-01

    An updated national ammonia (NH 3 ) emissions inventory was employed to study the relationship between NH 3 emissions and livestock industries in Canada. Emissions from animal agriculture accounted for 322 kilotonnes (kt) or 64% of Canadian NH 3 emissions in 2002. Cattle and swine accounted for the bulk of livestock emissions. The provinces of Alberta, Ontario, Quebec, and Saskatchewan accounted for 28.1%, 22.0%, 18.7%, and 13.1% of total livestock emissions, respectively. Emissions from Ontario and Quebec were attributed to the intensive production of dairy, hogs and poultry. Dairy cattle emissions per hectolitre of milk were higher in Ontario and Quebec than in other provinces, while swine emissions per livestock unit were higher than either beef or dairy cattle. A review of the abatement literature indicated diet manipulation to improve N efficiency and land spreading methods are very effective techniques to lower NH 3 emissions. Future research is required to evaluate the feasibility of biofilters and feces/urine separation methods. - Livestock NH 3 emissions are higher in areas characterized by intensive livestock production with diet manipulation and land spreading offering the greatest potential for NH 3 abatement options.

  14. A meta-analysis of the greenhouse gas abatement of bioenergy factoring in land use changes.

    El Akkari, M; Réchauchère, O; Bispo, A; Gabrielle, B; Makowski, D

    2018-06-04

    Non-food biomass production is developing rapidly to fuel the bioenergy sector and substitute dwindling fossil resources, which is likely to impact land-use patterns worldwide. Recent publications attempting to factor this effect into the climate mitigation potential of bioenergy chains have come to widely variable conclusions depending on their scope, data sources or methodology. Here, we conducted a first of its kind, systematic review of scientific literature on this topic and derived quantitative trends through a meta-analysis. We showed that second-generation biofuels and bioelectricity have a larger greenhouse gas (GHG) abatement potential than first generation biofuels, and stand the best chances (with a 80 to 90% probability range) of achieving a 50% reduction compared to fossil fuels. Conversely, directly converting forest ecosystems to produce bioenergy feedstock appeared as the worst-case scenario, systematically leading to negative GHG savings. On the other hand, converting grassland appeared to be a better option and entailed a 60% chance of halving GHG emissions compared to fossil energy sources. Since most climate mitigation scenarios assume still larger savings, it is critical to gain better insight into land-use change effects to provide a more realistic estimate of the mitigation potential associated with bioenergy.

  15. Nitrous Oxide Abatement Coupled with Biopolymer Production As a Model GHG Biorefinery for Cost-Effective Climate Change Mitigation.

    Frutos, Osvaldo D; Cortes, Irene; Cantera, Sara; Arnaiz, Esther; Lebrero, Raquel; Muñoz, Raúl

    2017-06-06

    N 2 O represents ∼6% of the global greenhouse gas emission inventory and the most important O 3 -depleting substance emitted in this 21st century. Despite its environmental relevance, little attention has been given to cost-effective and environmentally friendly N 2 O abatement methods. Here we examined, the potential of a bubble column (BCR) and an internal loop airlift (ALR) bioreactors of 2.3 L for the abatement of N 2 O from a nitric acid plant emission. The process was based on the biological reduction of N 2 O by Paracoccus denitrificans using methanol as a carbon/electron source. Two nitrogen limiting strategies were also tested for the coproduction of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) coupled with N 2 O reduction. High N 2 O removal efficiencies (REs) (≈87%) together with a low PHBV cell accumulation were observed in both bioreactors in excess of nitrogen. However, PHBV contents of 38-64% were recorded under N limiting conditions along with N 2 O-REs of ≈57% and ≈84% in the ALR and BCR, respectively. Fluorescence in situ hybridization analyses showed that P. denitrificans was dominant (>50%) after 6 months of experimentation. The successful abatement of N 2 O concomitant with PHBV accumulation confirmed the potential of integrating biorefinery concepts into biological gas treatment for a cost-effective GHG mitigation.

  16. Potential impact on air pollution from ambitious national CO2 emission abatement strategies in the Nordic countries – environmental links between the UNFCCC and the UNECE – CLRTAP

    Åström, Stefan; Tohka, Antti; Bak, Jesper; Lindblad, Maria; Arnell, Jenny

    2013-01-01

    This article presents results from a meta-study of Nordic low carbon dioxide (CO 2 ) emission scenarios. The focus of the study was to explore possible environmental impacts if selected Nordic low CO 2 emission scenarios were achieved by 2020. The impacts of concern were climate change, acidification, eutrophication and human health. Results from this study indicate that large scale reduction of CO 2 emissions by 2020 in a Nordic energy system requires large scale penetration of technical measures and structural changes. The environmental improvements achieved would most often facilitate achievement of air pollution targets as well as post-Kyoto targets for greenhouse gas (GHG) emissions. All scenarios do, however, not imply co-benefits between air pollution and CO 2 emission reductions and the net impact on climate change could be smaller than anticipated. A conclusion is that co-benefits and risks for trade-offs between air quality and climate change should be emphasised in the development of low-CO 2 energy and emission strategies. - Highlights: ► CO 2 abatement strategies differ in impact on environment, human health and climate. ► Bio fuel CO 2 strategies can imply smaller climate and environmental benefits. ► Nordic ‘clean’ electricity export can give environmental benefits if replacing coal.

  17. Recyclables Valorisation as the Best Strategy for Achieving Landfill CO2e Emissions Abatement from Domestic Waste: Game Theory

    Paul Taboada-González

    2017-07-01

    Full Text Available Various nations in the world have developed technologies and strategies for appropriate waste disposal, and to abate waste generation and greenhouse gasses. Alternatives like recovering materials can help, but they require reliable information to improve planning and management. This study quantifies the Carbon dioxide (CO2 emissions produced by the lack of valorisation of materials in a Mexican city. Two waste characterisations in a lower-class neighbourhood were carried out. For the CO2 emission estimation, two scenarios were considered. DEFRA emission factors for waste treatment processes were used. Waste generation was 0.64 kg/capita/day in the first study, and 0.50 kg/capita/day in the second. The CO2eq emissions of collected waste in the neighbourhood were estimated at 1824 kg for 2013 (0.20 kg/capita/day and 1636 kg for 2015 (0.19 kg/capita/day. The behaviour of solid waste management in the city can be explained by the “prisoner’s dilemma” model, studied in game theory, which is ideally suited to analysing situations affected by multiple agents, but requires an accurate understanding of solid waste actors and social implications.

  19. The potential role of nuclear energy in greenhouse gas abatement strategies

    Cobb, J.; Cornish, E.

    2000-01-01

    Nuclear energy will make a significant contribution to meeting the world's future electricity demand while helping reduce greenhouse gas emissions. However the scale of that contribution will be strongly influenced by the way in which this contribution is recognised in national and international policies designed to tackle climate change. The debate continues to rage over the science of climate change: is climate change the result of human intervention or is it a naturally occurring phenomenon? The majority of scientists involved in this debate would agree that enhanced global warming, as witnessed in recent years, has come about as a result of the massive explosion in greenhouse gas emissions since the beginning of the industrial era. This paper will give an overview of the institutions and organisations involved in the international climate change negotiations. It will describe the political positions of different countries on their perceived role of nuclear power in mechanisms designed to reduce greenhouse gas emissions. The paper will also give an insight into the financial impact of assigning a value to carbon emissions and how that might change the relative economics of nuclear power in comparison to fossil fuel generation

  20. The potential role of nuclear energy in greenhouse gas abatement strategies

    Cobb, J.; Cornish, E.

    2002-01-01

    Nuclear energy plays an essential role in avoiding greenhouse gas emissions. The contribution of nuclear power to electricity supplies has grown rapidly since the 1970's. As of July 2000, 432 power reactors were in operation in 31 countries. Nuclear power provided some 2300 TWh. This is about 17% of the world's total electricity, or 7% of total primary energy. This contribution avoids the emissions of about 2300 million tonnes of carbon dioxide annually, assuming that it would otherwise be provided mainly by coal-fired plants. This represents nearly one-third of the carbon dioxide presently emitted by power generation. Since electricity generation accounts for about 30% of all anthropogenic carbon dioxide emissions, total emissions would be about 10% higher if it were not for nuclear power. In contrast, the objective of the Kyoto Protocol is to reduce greenhouse gas emissions in industrialized nations by 5% by 2008-12 compared to a 1990 baseline. In order for atmospheric greenhouse gas concentrations to be stabilized at a sustainable level, it will be necessary to reduce emissions by around 60% from the 1990 level. Advocates of a policy of 'convergence and contraction', where developed and developing countries are to be allowed similar levels of emissions on a per capita basis, state that developed countries may have to reduce emissions by as much as 80%. Nuclear energy will make a significant contribution to meeting the world's future electricity demand while helping reduce greenhouse gas emissions. However, the scale of that contribution will be strongly influenced by the way in which this contribution is recognized in national and international policies designed to tackle climate change. The debate continues to rage over the science of climate change: is climate change the result of human intervention or is it a naturally occurring phenomenon? The majority of scientists involved in this debate would agree that enhanced global warming, as witnessed in recent

  1. The timing of biological carbon sequestration and carbon abatement in the energy sector under optimal strategies against climate risks

    Gitz, V.; Hourcade, J.Ch.; Ciais, Ph.

    2005-10-01

    This paper addresses the timing of the use of biological carbon sequestration and its capacity to alleviate the carbon constraint on the energy sector. We constructed a stochastic optimal control model balancing the costs of fossil emission abatement, the opportunity costs of lands allocated to afforestation, and the costs of uncertain climate damages. We show that a minor part of the sequestration potential should start immediately as a 'brake', slowing down both the rate of growth of concentrations and the rate of abatement in the energy sector. thus increasing the option value of the emission trajectories. But, most of the potential is put in reserve to be used as a 'safety valve' after the resolution of uncertainty, if a higher and faster decarbonization is required: sequestration cuts off the peaks of costs of fossil abatement and postpones the pivoting of the energy system by up to two decades.

  3. The nitrogen abatement cost in wetlands

    Bystroem, Olof

    1998-01-01

    The costs of abating agricultural nitrogen pollution in wetlands are estimated. By linking costs for construction of wetlands to the denitrification capacity of wetlands, an abatement cost function can be formed. A construction-cost function and a denitrification function for wetlands is estimated empirically. This paper establishes a link between abatement costs and the nitrogen load on wetlands. Since abatement costs fluctuate with nitrogen load, ignoring this link results in incorrect estimates of abatement costs. The results demonstrate that wetlands have the capacity to provide low cost abatement of nitrogen compounds in runoff. For the Kattegatt region in Sweden, marginal abatement costs for wetlands are shown to be lower than costs of land use changing measures, such as extended land under fallow or cultivation of fuel woods, but higher than the marginal costs of reducing nitrogen fertilizer

  5. Climate Change and Children: Health Risks of Abatement Inaction, Health Gains from Action

    Anthony J McMichael

    2014-08-01

    Full Text Available As human-driven climate change advances, many adults fret about the losses of livelihoods, houses and farms that may result. Children fret about their parents’ worries and about information they hear, but do not really understand about the world’s climate and perhaps about their own futures. In chronically worried or anxious children, blood cortisol levels rise and adverse changes accrue in various organ systems that prefigure adult-life diseases. Meanwhile, for many millions of children in poor countries who hear little news and live with day-to-day fatalism, climate change threatens the fundamentals of life—food sufficiency, safe drinking water and physical security—and heightens the risks of diarrhoeal disease, malaria and other climate-sensitive infections. Poor and disadvantaged populations, and especially their children, will bear the brunt of climate-related trauma, disease and premature death over the next few decades and, less directly, from social disruption, impoverishment and displacement. The recent droughts in Somalia as the Indian Ocean warmed and monsoonal rains failed, on top of chronic civil war, forced hundreds of thousands of Somali families into north-eastern Kenya’s vast Dadaab refugee camps, where, for children, shortages of food, water, hygiene and schooling has endangered physical, emotional and mental health. Children warrant special concern, both as children per se and as the coming generation likely to face ever more extreme climate conditions later this century. As children, they face diverse risks, from violent weather, proliferating aeroallergens, heat extremes and mobilised microbes, through to reduced recreational facilities, chronic anxieties about the future and health hazards of displacement and local resource conflict. Many will come to regard their parents’ generation and complacency as culpable.

    2012-06-01

    Strategies that are most effective in both prevention and management of chronic disease consider factors such as age, ethnicity, community, and technology. Most behavioral change strategies derive their components from application of the health belief model, the theory of reasoned action/theory of planned behavior, transtheoretical model, and social cognitive theory. Many tools such as the readiness ruler and personalized action plan form are available to assist health care teams to facilitate healthy behavior change. Primary care providers can support behavior changes by providing venues for peer interventions and family meetings and by making new partnerships with community organizations.

  9. Assessing the effects of noise abatement measures on health risks: A case study in Istanbul

    Ongel, Aybike; Sezgin, Fatih

    2016-01-01

    In recent decades, noise pollution caused by industrialization and increased motorization has become a major concern around the world because of its adverse effects on human well-being. Therefore, transportation agencies have been implementing noise abatement measures in order to reduce road traffic noise. However, limited attention is given to noise in environmental assessment of road transportation systems. This paper presents a framework for a health impact assessment model for road transportation noise emissions. The model allows noise impacts to be addressed with the health effects of air pollutant and greenhouse gas emissions from road transportation. The health damages assessed in the model include annoyance, sleep disturbance, and cardiovascular disease in terms of acute myocardial infarction. The model was applied in a case study in Istanbul in order to evaluate the change in health risks from the implementation of noise abatement strategies. The noise abatement strategies evaluated include altering pavement surfaces in order to absorb noise and introducing speed limits. It was shown that significant improvements in health risks can be achieved using open graded pavement surfaces and introducing speed limits on highways. - Highlights: • Transportation noise has a significant effect on health. • Noise should be included in the environmental assessment of transportation systems. • Traffic noise abatement measures include noise reducing pavements and speed limits. • Noise abatement measures help reduce the health risks of transportation noise. • Speed limit reduction on uncongested roads is an effective way to reduce health risks.

The model allows noise impacts to be addressed with the health effects of air pollutant and greenhouse gas emissions from road transportation. The health damages assessed in the model include annoyance, sleep disturbance, and cardiovascular disease in terms of acute myocardial infarction. The model was applied in a case study in Istanbul in order to evaluate the change in health risks from the implementation of noise abatement strategies. The noise abatement strategies evaluated include altering pavement surfaces in order to absorb noise and introducing speed limits. It was shown that significant improvements in health risks can be achieved using open graded pavement surfaces and introducing speed limits on highways. - Highlights: • Transportation noise has a significant effect on health. • Noise should be included in the environmental assessment of transportation systems. • Traffic noise abatement measures include noise reducing pavements and speed limits. • Noise abatement measures help reduce the health risks of transportation noise. • Speed limit reduction on uncongested roads is an effective way to reduce health risks.

    Climate change is not only dangerous but also expensive. On the other hand, air pollution abatement measures are costly as well. Scientists of the Microeconomics Department investigated how air pollution abatement and cost efficiency can best be combined. (orig.)

  12. Abatement of tropospheric ozone: effects of strategies to improve air quality on public health and other sectors.

    Guest, C S; Morgan, P; Moss, J R; Woodward, A J; McMichael, A J

    1996-06-01

    The National Health and Medical Research Council's air quality goal for ozone in the troposphere (near the earth's surface) is 0.12 parts per million (ppm), averaged over one hour, similar to the United States standard, but less stringent than the guideline for Europe. We aimed to identify the environmental, economic and social changes that would be associated with changing the goal. Methods included literature review, economic assessments and group interviews. The group to benefit from lower exposures may include outdoor workers, school children and people not in regular day-time work indoors, because ozone is most prevalent during the daylight hours of the warmer months. A lower level could improve the yield of some crops. The causes and effects of tropospheric ozone are not appreciated except among groups with relevant commercial, industrial or scientific experience. However, the consultations identified frustration about the social problems caused by dependence on private motor vehicles. Short-term costs of compliance with a more stringent goal would fall principally on the users of transport. The value of the benefits was enough for many to support making the ozone goal more stringent, but those who required a demonstration of financial benefit (even including savings of health care costs) did not support any change to the goal. Based primarily on averted detriment to health, we recommend the more stringent level of 0.08 ppm (one-hour average) as the goal for the year 2005 in Australia and elsewhere. The addition of a goal with longer averaging time is also proposed.

  14. Market Strategies for Climate Change

    Kolk, A.; Pinkse, J. [Business School, University of Amsterdam, Amsterdam (Netherlands)

    2004-06-01

    The issue of climate change has attracted increasing business attention in the past decade. Whereas companies initially aimed primarily at influencing the policy debate, corporate strategies increasingly include economic responses. Existing classifications for climate change strategies however still reflect the political, non-market components. Using empirical information from the largest multinational companies worldwide, this article examines current market responses, focusing on the drivers (threats and opportunities) and the actions being taken by companies to address climate change. It also develops a typology of climate strategies that addresses the market dimensions, covering both the aim (strategic intent) and the degree of cooperation (form of organisation). The aim turns out to be either innovation or compensation, while the organisational arrangements to reach this objective can be oriented at the company level (internal), at companies' own supply chain (vertical) or at cooperation with other companies (competitors or companies in other sectors - horizontal). The typology can assist managers in deciding about the strategic option(s) they want to choose regarding climate change, also based on the insights offered by the paper about the current state of activities of other companies worldwide.

  15. Save water to save carbon and money: developing abatement costs for expanded greenhouse gas reduction portfolios.

    Stokes, Jennifer R; Hendrickson, Thomas P; Horvath, Arpad

    2014-12-02

    The water-energy nexus is of growing interest for researchers and policy makers because the two critical resources are interdependent. Their provision and consumption contribute to climate change through the release of greenhouse gases (GHGs). This research considers the potential for conserving both energy and water resources by measuring the life-cycle economic efficiency of greenhouse gas reductions through the water loss control technologies of pressure management and leak management. These costs are compared to other GHG abatement technologies: lighting, building insulation, electricity generation, and passenger transportation. Each cost is calculated using a bottom-up approach where regional and temporal variations for three different California water utilities are applied to all alternatives. The costs and abatement potential for each technology are displayed on an environmental abatement cost curve. The results reveal that water loss control can reduce GHGs at lower cost than other technologies and well below California's expected carbon trading price floor. One utility with an energy-intensive water supply could abate 135,000 Mg of GHGs between 2014 and 2035 and save--rather than spend--more than $130/Mg using the water loss control strategies evaluated. Water loss control technologies therefore should be considered in GHG abatement portfolios for utilities and policy makers.

  16. Greenhouse Gas and Ammonia Emissions from Different Stages of Liquid Manure Management Chains: Abatement Options and Emission Interactions.

    Mohankumar Sajeev, Erangu Purath; Winiwarter, Wilfried; Amon, Barbara

    2018-01-01

    Farm livestock manure is an important source of ammonia and greenhouse gases. Concerns over the environmental impact of emissions from manure management have resulted in research efforts focusing on emission abatement. However, questions regarding the successful abatement of manure-related emissions remain. This study uses a meta-analytical approach comprising 89 peer-reviewed studies to quantify emission reduction potentials of abatement options for liquid manure management chains from cattle and pigs. Analyses of emission reductions highlight the importance of accounting for interactions between emissions. Only three out of the eight abatement options considered (frequent removal of manure, anaerobic digesters, and manure acidification) reduced ammonia (3-60%), nitrous oxide (21-55%), and methane (29-74%) emissions simultaneously, whereas in all other cases, tradeoffs were identified. The results demonstrate that a shift from single-stage emission abatement options towards a whole-chain perspective is vital in reducing overall emissions along the manure management chain. The study also identifies some key elements like proper clustering, reporting of influencing factors, and explicitly describing assumptions associated with abatement options that can reduce variability in emission reduction estimates. Prioritization of abatement options according to their functioning can help to determine low-risk emission reduction options, specifically options that alter manure characteristics (e.g., reduced protein diets, anaerobic digestion, or slurry acidification). These insights supported by comprehensive emission measurement studies can help improve the effectiveness of emission abatement and harmonize strategies aimed at reducing air pollution and climate change simultaneously.

  17. A Climate Change Adaptation Strategy for Management of ...

    Sea level rise is causing shoreline erosion, increased coastal flooding, and marsh vulnerability to the impact of storms. Coastal marshes provide flood abatement, carbon and nutrient sequestration, water quality maintenance, and habitat for fish, shellfish, and wildlife, including species of concern, such as the saltmarsh sparrow (Ammodramus caudacutus). We present a climate change adaptation strategy (CCAS) adopted by scientific, management, and policy stakeholders for managing coastal marshes and enhancing system resiliency. A common adaptive management approach previously used for restoration projects was modified to identify climate-related vulnerabilities and plan climate change adaptive actions. As an example of implementation of the CCAS, we describe the stakeholder plans and management actions the US Fish and Wildlife Service and partners developed to build coastal resiliency in the Narrow River Estuary, RI, in the aftermath of Superstorm Sandy. When possible, an experimental BACI (before-after, control-impact) design, described as pre- and post-sampling at the impact site and one or more control sites, was incorporated into the climate change adaptation and implementation plans. Specific climate change adaptive actions and monitoring plans are described and include shoreline stabilization, restoring marsh drainage, increasing marsh elevation, and enabling upland marsh migration. The CCAS provides a framework and methodology for successfully managing coa

  18. The public health relevance of air pollution abatement.

    Künzli, N

    2002-07-01

    Assuming a causal relationship between current levels of air pollution and morbidity/mortality, it is crucial to estimate the public health relevance of the problem. The derivation of air pollution attributable cases faces inherent uncertainties and requires influential assumptions. Based on the results of the trinational impact assessment study of Austria, France, and Switzerland, where prudent estimates of the air pollution attributable cases (mortality, chronic bronchitis incidence, hospital admissions, acute bronchitis among children, restricted activity days, asthma attacks) have been made, influential uncertainties are quantified in this review. The public health impact of smoking, environmental tobacco smoke, and air pollution on the prevalence of chronic cough/phlegm are outlined. Despite all methodological caveats, impact assessment studies clearly suggest that public health largely benefits from better air quality. The studies are selective underestimates as they are strongly driven by mortality, but do not include full quantification of the impact on morbidity and their consequences on quality of life among the diseased and the caregivers. Air pollution abatement strategies are usually political in nature, targeting at polities, regulation and technology in mobile or stationary sources rather than at individuals. It is of note that key clean air strategies converge into abatement of climate change. In general, energy consumption is very closely related to both air pollution and greenhouse gases. The dominant causes of both problems are the excessive and inefficient combustion of fossil fuel. Thus, for many policy options, the benefit of air pollution abatement will go far beyond what prudent health-impact assessments may derive. From a climate change and air pollution perspective, improved energy efficiency and a strong and decisive departure from the "fossil fuel" combustion society is a science-based must. Health professionals must raise their voices

  1. On the cost-effective abatement of CO2-options taking consumer behaviour into account

    Wietschel, M.; Rentz, O.

    1995-01-01

    The current ecopolitical discussion focusses on the greenhouse effect and the consequent political aim to abate anthropogenic CO 2 emissions. Studies on individual measures for CO 2 abatement and on the development of efficient abatement strategies are already at hand. There is one aspect, however, that has hardly been dealt with as yet: If CO 2 abatement suceeds as it is planned by the Federal Government, then energy and prices will rise considerably, and this will curb the demand for energy. Any efficient abatement strategy must take this into account. The article presents a new concept for energy-emission models that takes consumer behaviour into account and discusses efficient CO 2 abatement strategies following from the application of such models.

    2013-10-01

    Removal of enzyme inhibitors released during lignocellulose pretreatment is essential for economically feasible biofuel production. We tested bio-abatement to mitigate enzyme inhibitor effects observed in corn stover liquors after pretreatment with either dilute acid or liquid hot water at 10% (w/v) solids. Bio-abatement of liquors was followed by enzymatic hydrolysis of cellulose. To distinguish between inhibitor effects on enzymes and recalcitrance of the substrate, pretreated corn stover solids were removed and replaced with 1% (w/v) Solka Floc. Cellulose conversion in the presence of bio-abated liquors from dilute acid pretreatment was 8.6% (0.1x enzyme) and 16% (1x enzyme) higher than control (non-abated) samples. In the presence of bio-abated liquor from liquid hot water pretreated corn stover, 10% (0.1x enzyme) and 13% (1x enzyme) higher cellulose conversion was obtained compared to control. Bio-abatement yielded improved enzyme hydrolysis in the same range as that obtained using a chemical (overliming) method for mitigating inhibitors. Copyright © 2013 Elsevier Ltd.

    This article reviews and develops theoretical and empirical representations of economic incentives for implementing pollution control strategies. A number of alternative economic instruments exist, which, if applied internationally, could encourage implementation of abatement strategies by counties. The article considers means of persuading countries to minimize abatement costs. A comparison between the pollution targets achieved by the imposition of a uniform charge rate and by differentiated charge rates is discussed, and empirical results are provided with associated conclusions. These results are compared with a simple standards setting in the form of critical loads, in order to assess empirically if economic instruments work better than regulations

  10. Helsinki Metropolitan Area Climate Change Adaptation Strategy

    NONE

    2012-07-01

    The Helsinki Metropolitan Area Climate Change Adaptation Strategy has been prepared in close cooperation with the four cities of the metropolitan area (Helsinki, Espoo, Vantaa and Kauniainen), the Helsinki Region Environmental Services Authority HSY and other municipal, regional and state level organisations. In the strategy, strategic starting points and policies with which the metropolitan area prepares for the consequences of climate change, are compiled. The Helsinki Metropolitan Area adaptation strategy concentrates on the adaptation of the built and urban environment to the changing climate. The vision of the strategy is climate proof city - the future is built now. The strategy aims to (1) assess the impacts of climate change in the area, (2) prepare for the impacts of climate change and to extreme weather events and (3) to reduce the vulnerabilities of the area to climate variability and change. The target is to secure the well-being of the citizens and the functioning of the cities also in the changing climate conditions. The preparation of the adaptation strategy started in 2009 by producing the background studies. They include the regional climate and sea level scenarios, modelling of river floods in climate change conditions and a survey of climate change impacts in the region. Also, existing programmes, legislation, research and studies concerning adaptation were collected. The background studies are published in a report titled 'The Helsinki metropolitan area climate is changing - Adaptation strategy background studies' (in Finnish) (HSY 2010). HSY coordinated the strategy preparation. The work was carried out is close cooperation with the experts of the metropolitan area cities, regional emergency services, Ministry of the Environment, Helsinki Region Transport Authority and other regional organisations. The strategy work has had a steering group that consists of representatives of the cities and other central cooperation partners. The

  11. Measurements of environmental policy for air pollution abatement

    Friedrich, R.

    1993-01-01

    The first part of the study goes into the determination of efficient strategies for the reduction of air pollutants. The developed method is not only derived theoretically but is tested with the concrete example of emissions sources of a German state. The second part goes into the question what the government can do in order to attain that air pollution abatement measures recognized as being efficient will be put into practice. As market economy mechanisms have advantages over central state planning in the allocation of economic resources the question arises if not also for environmental protection market economy tools may contribute to an improvement of the efficiency of air pollution abatement. Therefore the suitability of different tools of environmental policy for the realization of efficient air pollution abatement is investigated and evaluated. This is again not done abstractly but with existing emission sources. (orig./HSCH). 32 figs., 12 tabs [de

  12. A New Strategy for Mitigating Climate Change

    Kaya, Y.; Akimoto, K./ Oda, J.

    2007-07-01

    This paper proposes a new strategy for mitigating climate change, both in short term and in long term. The basic character of the strategy is action oriented with multi-country collaboration, while the Framework Convention on Climate Change (FCCC) and Kyoto protocol is numerical target oriented within United Nation Framework. The introductory part of the paper briefly describes deficits of FCCC and Kyoto protocol and the needs of a different strategy for mitigating climate change. Then the short term strategy is focused on energy conservation and its effectiveness for mitigating climate change is illustrated by estimating the potential of reducing CO{sub 2} emission when intense collaboration is achieved for distributing main energy conservation measures in power generation and key industries among Asia Pacific Partnership countries. The long term strategy is developing novel types of renewables among countries. Geoheat and space solar power systems (SSPS) are candidates which may be developed among major developed countries. Necessity of international collaboration is stressed for R and D of these candidate renewables. (auth)

    A number of questions having to do with the themes of abatement and adaptation are discussed. Under the first rubric are questions of future concentrations of radiatively active trace gases, the linkage of these gases with greenhouse warming, and other environmental problems. Also examined in the abatement context are opportunities to reduce fossil fuel use and therefore the emission of greenhouse gases, and the likelihood that natural forest expansion may provide an opportunity to control the rate of carbon dioxide (CO2) accumulation in the atmosphere. Also discussed are the possible effects of greenhouse warming on agriculture in the United States and in the developing world. Finally, some suggestions are given on capturing and retaining interest in greenhouse warming on the part of the decision making public

  17. Dynamics of carbon abatement in the Second Generation Model

    Sands, Ronald D.

    2004-01-01

    The Second Generation Model (SGM) is a collection of computable-general-equilibrium models developed for analysis of policies to reduce greenhouse gas emissions. Behavior of the Second Generation Model, with respect to changes in carbon prices, can be summarized using marginal abatement cost curves. Marginal abatement costs vary over time, as capital stocks adjust to a new set of prices, and across countries, depending in part on the mix of fuels in the existing energy system. This paper documents the production structure in SGM, marginal abatement cost curves derived from SGM with constant-carbon-price experiments, an application to several Energy Modeling Forum scenarios, and a methodology for including carbon capture and disposal in SGM

  18. Canada's National Implementation Strategy on Climate Change

    2000-10-01

    This document describes the national implementation strategy which is a part of the coordinated national response to climate change. The approach was developed from the National Climate Change process, established by the federal, provincial and territorial ministers responsible for energy and the environment, based on an examination of the impacts, costs and benefits of implementing the Kyoto Protocol, as well as the options for addressing climate change. The Strategy involves (1) taking action to reduce risks and to improve our understanding of risks associated with climate change, (2) institution of a national framework that includes individual and joint action, while recognizing jurisdictional flexibility in responding to unique circumstances, (3) adopting a phased approach, (4) progressive action in response to changing domestic and international circumstances, (5) clear understanding of the necessary relationship between international and national strategies, (6) developing an understanding of the implications of emission reduction targets and major options, including cross-cutting policy approaches such as emissions trading and allocation of responsibility for reducing emissions. The Strategy uses a risk-management approach that attempts to limit the risks of climate change while maximizing opportunities for Canada to contribute to global and national solutions. This approach incorporates improving scientific and analytical understanding and co-ordinating national and international action and a phased approach to implementation. This policy document focuses on Phase One actions which consist of five connected themes, i. e. enhancing awareness and understanding, promoting technology development and innovation, governments leading by example, investing in knowledge and building the foundation, and encouraging action. Future phases will be linked to greater international certainty based on ratification of the Kyoto Protocol, the actions of our trading partners

  19. Assessment of Clmate Change Mitigation Strategies for the Road Transport Sector of India

    Singh, N.; Mishra, T.; Banerjee, R.

    2017-12-01

    India is one of the fastest growing major economies of the world. It imports three quarters of its oil demand, making transport sector major contributor of greenhouse gas (GHG) emissions. 40% of oil consumption in India comes from transport sector and over 90% of energy demand is from road transport sector. This has led to serious increase in CO2 emission and concentration of air pollutants in India. According to Intergovernmental Panel on Climate Change (IPCC), transport can play a crucial role for mitigation of global greenhouse gas emissions. Therefore, assessment of appropriate mitigation policies is required for emission reduction and cost benefit potential. The present study aims to estimate CO2, SO2, PM and NOx emissions from the road transport sector for the base year (2014) and target year (2030) by applying bottom up emission inventory model. Effectiveness of different mitigation strategies like inclusion of natural gas as alternate fuel, penetration of electric vehicle as alternate vehicle, improvement of fuel efficiency and increase share of public transport is evaluated for the target year. Emission reduction achieved from each mitigation strategies in the target year (2030) is compared with the business as usual scenario for the same year. To obtain cost benefit analysis, marginal abatement cost for each mitigation strategy is estimated. The study evaluates mitigation strategies not only on the basis of emission reduction potential but also on their cost saving potential.

  6. EU energy and climate change strategy

    Graça Carvalho, Maria da

    2012-01-01

    This paper will summarise the European Strategy for Energy and Climate Change. In current international negotiations Europe has proposed a 20% reduction in GHG (greenhouse gases) in the developed countries by 2020 or 30% should there be an international agreement in the domain. However it is important to define measures to achieve the targets. One of the principal tools is to improve energy efficiency under the energy efficiency action plan, which will help to achieve a 20% energy saving by 2020. On the other hand, the amount of energy from renewable sources consumed in Europe will have to rise from its current level of 8.5%–20% by 2020. These are ambitious but achievable targets. Nonetheless, these can only be achieved through strong investment in areas of the knowledge triangle which strengthens research and innovation in the energy sector in Europe. The paper covers European Energy and Climate Change Policy, the European Strategic Energy Technology plan, the consequences of the Lisbon Treaty, European and national Road maps to a low carbon economy, the Energy Efficiency Plan for 2011 and finishes with a brief consideration of the EU’s energy infrastructure priorities. -- Highlights: ► This paper summarises the European Strategy for Energy and Climate Change. ► Reduction of GHG emissions by 30%-international agreement or −20% without agreement. ► Use of 20% of renewable energies by 2020. ► Increase of energy efficiency of 20% by 2020. ► Consolidating of the internal energy market.

  7. Conservation strategies, sustainable development and climate change

    Manning, E.; Rizzo, B.; Wiken, E.

    1990-01-01

    The relationship between conservation strategies, sustainable development and climatic change is discussed. A broad conceptual model of environment-economy relationships is introduced, which can aid in understanding the sources of the stresses put on the environment and the ability of the environment to respond. The supply side of the model introduces the concept of the environment as a source of environmental functions, each distinguishable part of which can be described in terms of a range of biological or physical variables. These functions have the potential to produce an extensive range of goods, services, values, etc. The demand side of the model is population powered and anthropocentric. Transformation functions occur to alter the supply to satisfy the demand, and may range from picking an apple to combinations of transport, combination, distillation and packaging of many different substances. Climate change can be viewed as one of the most significant feedbacks from our demands on the resource base, most particularly from the transformation functions used. Conservation strategies are a means to try to address concerns with all areas of the system embodied in the model. 36 refs., 4 figs

  8. Marginal abatement cost curves in general equilibrium: The influence of world energy prices

    Klepper, Gernot; Peterson, Sonja

    2006-01-01

    Marginal abatement cost curves (MACCs) are a favorite instrument to analyze international emissions trading. This paper focuses on the question of how to define MACCs in a general equilibrium context where the global abatement level influences energy prices and in turn national MACCs. We discuss the mechanisms theoretically and then use the CGE model DART for quantitative simulations. The result is, that changes in energy prices resulting from different global abatement levels do indeed affect national MACCs. Also, we compare different possibilities of defining MACCs-of which some are robust against changes in energy prices while others vary considerably. (author)

  9. Endogenous Technological Progress with Uncertainty and Carbon Abatement Polices

    Cho, G.L. [Korea Energy Economics Institute, Euiwang (Korea)

    2001-11-01

    Most greenhouse gas abatement policy models tend to neglect a potentially important element that is relevant to the induced technology changes(ITC). These models that incorporate technological change treat such a change as autonomous, that is, unaffected by changes in prices brought about by policy reforms. However, climate change policies can create economic incentives to engage in more extensive R and D oriented toward the discovery of new production techniques that mitigate a reliance on convectional fuels, ultimately resulting in impacts on the policies themselves. In order to investigate the significance of induced technology for the attractiveness of abatement policies, this study develop the multi-sectoral dynamic CGE model by incorporating two characteristics of technological progress: the endogenous growth model with externality of technology in Romer (1986) and Lucas(1988) and the technological changes resulting from profit maximizing investment in R and D in Rebelo(1991) and Jones and Manuelli(1990). Furthermore, technological progress is affected by not only the economical factors but also the political and institutional system that cannot be captured in this model. This study considers such uncertainty in the technological progress as technology shock as in RBC school. This study shows that the presence of ITC implies lower costs of achieving a given abatement target in terms of the reduction cost per ton of carbon and GDP losses. The presence of ITC reduces the GDP losses by 0.9%p{approx}1.5%p compared with the absence of the ITC. As the abatement target is substantially high, R and D is reduced significantly even in the presence of ITC. Therefore, it is necessary to seriously consider the tax recycling for enhancing R and D investment, which minimizes the GDP losses. The reduction cost is highly sensitive to the uncertainty in technological progress. The technology shock leads the reduction cost to widely vary, in terms of standard deviation, 3

  10. Sex change strategy and the aromatase genes.

    Gardner, L; Anderson, T; Place, A R; Dixon, B; Elizur, A

    2005-04-01

    Sequential hermaphroditism is a common reproductive strategy in many teleosts. Steroid production is known to mediate both the natural and induced sex change, yet beyond this the physiology directing this process has received little attention. Cytochrome P450 aromatase is a key enzyme in the hormonal pathway catalysing the conversion of sex steroids, androgens to oestrogens, and thus is highly relevant to the process of sex change. This study reports the isolation of cDNA sequences for aromatase isoforms CYP19A1 and CYP19A2 from teleost species representing three forms of sexual hermaphroditism: Lates calcarifer (protandry), Cromileptes altivelis (protogyny), and Gobiodon histrio (bi-directional). Deduced amino acid analysis of these isoforms with other reported isoforms from gonochoristic (single sex) teleosts revealed 56-95% identity within the same isoform while only 48-65% identity between isoforms irrespective of species and sexual strategy. Phylogenetic analysis supported this result separating sequences into isoform exclusive clades in spite of species apparent evolutionary distance. Furthermore, this study isolates 5' flanking regions of all above genes and describes putative cis-acting elements therein. Elements identified include steroidogenic factor 1 binding site (SF-1), oestrogen response element (ERE), progesterone response element (PRE), androgen response element (ARE), glucocorticoid response elements (GRE), peroxisome proliferator-activated receptor alpha/retinoid X receptor alpha heterodimer responsive element (PPARalpha/RXRalpha), nuclear factor kappabeta (NF-kappabeta), SOX 5, SOX 9, and Wilms tumor suppressor (WTI). A hypothetical in vivo model was constructed for both isoforms highlighting potential roles of these putative cis-acting elements with reference to normal function and sexual hermaphroditism.

  11. Prospective life cycle carbon abatement for pyrolysis biochar systems in the UK

    Hammond, Jim; Shackley, Simon; Sohi, Saran; Brownsort, Peter

    2011-01-01

    Life cycle assessment (LCA) of slow pyrolysis biochar systems (PBS) in the UK for small, medium and large scale process chains and ten feedstocks was performed, assessing carbon abatement and electricity production. Pyrolysis biochar systems appear to offer greater carbon abatement than other bioenergy systems. Carbon abatement of 0.7-1.3 t CO 2 equivalent per oven dry tonne of feedstock processed was found. In terms of delivered energy, medium to large scale PBS abates 1.4-1.9 t CO 2 e/MWh, which compares to average carbon emissions of 0.05-0.30 t CO 2 e/MWh for other bioenergy systems. The largest contribution to PBS carbon abatement is from the feedstock carbon stabilised in biochar (40-50%), followed by the less certain indirect effects of biochar in the soil (25-40%)-mainly due to increase in soil organic carbon levels. Change in soil organic carbon levels was found to be a key sensitivity. Electricity production off-setting emissions from fossil fuels accounted for 10-25% of carbon abatement. The LCA suggests that provided 43% of the carbon in the biochar remains stable, PBS will out-perform direct combustion of biomass at 33% efficiency in terms of carbon abatement, even if there is no beneficial effect upon soil organic carbon levels from biochar application. - Research highlights: → Biochar systems offer greater carbon abatement than combustion or gasification. → Carbon abatement of 0.7-1.4t CO 2 e/dry tonne of feedstock processed was found. → Change in soil organic carbon stocks induced by biochar is the key sensitivity. → Biochar systems produce less electricity then combustion or gasification.

  12. Climate and air quality-driven scenarios of ozone and aerosol precursor abatement

    In addition to causing domestic and regional environmental effects, many air pollutants contribute to radiative forcing (RF) of the climate system. However, climate effects are not considered when cost-effective abatement targets for these pollutants are established, nor are they included in current international climate agreements. We construct air pollution abatement scenarios in 2030 which target cost-effective reductions in RF in the EU, USA, and China and compare these to abatement scenarios which instead target regional ozone effects and particulate matter concentrations. Our analysis covers emissions of PM (fine, black carbon and organic carbon), SO 2 , NO x , CH 4 , VOCs, and CO. We find that the effect synergies are strong for PM/BC, VOC, CO and CH 4 . While an air quality strategy targeted at reducing ozone will also reduce RF, this will not be the case for a strategy targeting particulate matter. Abatement in China dominates RF reduction, but there are cheap abatement options also available in the EU and USA. The justification for international cooperation on air quality issues is underlined when the co-benefits of reduced RF are considered. Some species, most importantly SO 2 , contribute a negative forcing on climate. We suggest that given current knowledge, NO x and SO 2 should be ignored in RF-targeted abatement policies.

  14. Abate distribution and dengue control in rural Cambodia.

    Khun, Sokrin; Manderson, Lenore H

    2007-02-01

    Sustainable public health and community collaboration and partnerships are essential for the effective elimination of vector breeding sites to prevent dengue fever. A prerequisite is that community members appreciate the importance of the infection, understand its transmission and preventive activities, and are able to translate such knowledge to action. In this paper, we draw on an ethnographic study of two villages in the eastern province of Kampong Cham, using data collected from qualitative research methods and entomological surveys to describe community knowledge of the vector, practices related to the reduction of breeding sources, and the effectiveness of temephos to control larvae. During the study period, temephos (distributed as Abate) was applied in water containers only in the rainy season, although these containers were also positive with larvae in the dry season. Discarded containers, ignored in terms of control activities, had twice the number of larvae as water storage containers. The continued reliance on Abate creates financial and technical problems, while its inappropriate distribution raises the possibility of larvicide resistance. Based on research findings, we argue that control strategies emphasizing the use of Abate should be reconsidered.

  15. Energy balance and GHG-abatement cost of cassava utilization for fuel ethanol in Thailand

    Nguyen, Thu Lan Thi; Gheewala, Shabbir H.; Garivait, Savitri

    2007-01-01

    Since 2001, in order to enhance ethanol's cost competitiveness with gasoline, the Thai government has approved the exemption of excise tax imposed on ethanol, controlling the retail price of gasohol (a mixture of ethanol and gasoline at a ratio of 1:9) to be less than that of octane 95 gasoline, within a range not exceeding 1.5 baht a litre. The policy to promote ethanol for transport is being supported by its positive effects on energy security and climate change mitigation. An analysis of energy, greenhouse gas (GHG) balances and GHG abatement cost was done to evaluate fuel ethanol produced from cassava in Thailand. Positive energy balance of 22.4 MJ/L and net avoided GHG emission of 1.6 kg CO 2 eq./L found for cassava-based ethanol (CE) proved that it would be a good substitute for gasoline, effective in fossil energy saving and GHG reduction. With a GHG abatement cost of US$99 per tonne of CO 2 , CE is rather less cost effective than the many other climate strategies relevant to Thailand in the short term. Opportunities for improvements are discussed to make CE a reasonable option for national climate policy

  17. Marginal abatement cost curves and the optimal timing of mitigation measures

    Vogt-Schilb, Adrien; Hallegatte, Stéphane

    2014-01-01

    Decision makers facing abatement targets need to decide which abatement measures to implement, and in which order. Measure-explicit marginal abatement cost curves depict the cost and abating potential of available mitigation options. Using a simple intertemporal optimization model, we demonstrate why this information is not sufficient to design emission reduction strategies. Because the measures required to achieve ambitious emission reductions cannot be implemented overnight, the optimal strategy to reach a short-term target depends on longer-term targets. For instance, the best strategy to achieve European's −20% by 2020 target may be to implement some expensive, high-potential, and long-to-implement options required to meet the −75% by 2050 target. Using just the cheapest abatement options to reach the 2020 target can create a carbon-intensive lock-in and make the 2050 target too expensive to reach. Designing mitigation policies requires information on the speed at which various measures to curb greenhouse gas emissions can be implemented, in addition to the information on the costs and potential of such measures provided by marginal abatement cost curves. - Highlights: • Classification of existing Marginal Abatement Cost Curves (MACC). • MACCs do not provide separated data on the speed at which measures can be implemented. • Optimal measures to reach a short-term target depend on longer-term targets. • Unique carbon price or aggregated emission-reduction target may be insufficient. • Room for short-term sectoral policies if agents are myopic or governments cannot commit

  18. Prenatal stress changes learning strategies in adulthood.

    Schwabe, Lars; Bohbot, Veronique D; Wolf, Oliver T

    2012-11-01

    It is well known that stressful experiences may shape hippocampus-dependent learning and memory processes. However, although most studies focused on the impact of stress at the time of learning or memory testing, very little is known about how stress during critical periods of brain development affects learning and memory later in life. In this study, we asked whether prenatal stress exposure may influence the engagement of hippocampus-dependent spatial learning strategies and caudate nucleus-dependent response learning strategies in later life. To this end, we tested healthy participants whose mothers had experienced major negative life events during their pregnancy in a virtual navigation task that can be solved by spatial and response strategies. We found that young adults with prenatal stress used rigid response learning strategies more often than flexible spatial learning strategies compared with participants whose mothers did not experience major negative life events during pregnancy. Individual differences in acute or chronic stress do not account for these findings. Our data suggest that the engagement of hippocampal and nonhippocampal learning strategies may be influenced by stress very early in life. Copyright © 2012 Wiley Periodicals, Inc.

  3. CHANGE MANAGEMENT STRATEGIES RELATED TO THE GLOBAL ENVIRONMENT COMPLEXITY

    Elena DOVAL

    2016-12-01

    Full Text Available The changes in organizations appear as a reaction to the organizational environment changes. In order to manage these changes successfully, the managers need to anticipate and design alternative strategies by preparing different options.  Nevertheless, the complexity of the global environment forces the managers to adopt strategies for their organizations that are facilitating the creation of new strategic competences and competitive advantages to face the environmental rapid changes. In this context, this paper is aiming to illustrate the main directions the change management may consider to change the organization strategies in order to harmonize them to the external environment, such as: integration versus externalization, flexible specialization and flexible organization, standardization versus adaptation, market segmentation, relationship building and maintaining and communication integration.  However, the new strategies are based on a changed attitude of the managers towards the competitive advantage that is dynamic and focused on creation rather then to operations.

  4. Carbon dioxide abatement as a differential game

    Tahvonen, O.

    1993-01-01

    The report combines predictions on greenhouse warming, CO 2 abatement costs and adaptation costs in a differential game framework. The specified model makes it possible to solve the payoffs of the subgame perfect solution of a two state variable nonautonomous problem with N unequal countries. Abatement cost parameters are calibrated with a global energy sector model and climate parameters are based on empirical time series. Simulation suggests that the backstop technology assumption in the abatement cost model may imply drastic cuts in optimal emission levels. Compared to the Nash noncooperative equilibrium a pareto optimal agreement is found to be beneficial for developing countries but more costly for the industrial world. Given the present damage estimates, the losses due to an emission stabilizing agreement may be 400 times higher than maximum potential gains from cooperation

    Perhaps one of the most mysterious abatement procedures is that of the remediation of waterborne radon contamination in residential structures. Many mitigators have been led to believe that the use of GAC as an abatement technique is in appropriate due to the potential creation of a hazardous waste disposal problem. This paper sheds light on the use of GAC as a true alternative to costly aeration mitigation techniques, and can be used as a resource tool for mitigators who need to understand the limits of activity surrounding GAC, and what, if any, shielding may be needed for the protection of residential occupants

Initial effort has focused on providing strategic information and help to countries, on achieving offsets in greenhouse gas emissions by energy conservation or carbon sinking, and an emphasis on development of renewable energy supplies. The U.N. Development Agency has limited funding to help support startup on projects submitted. Specific examples are discussed in the areas of energy conservation and energy efficiency, adoption of renewable energy sources, and reducing the long-term costs of low greenhouse gas-emitting energy technologies.

  10. Flexible management: strategies for the changing workforce.

    Michaels, B

    1994-01-01

    In the year 2000, managers will supervise employees whose career aspirations differ drastically from their own. Success not only will be measured by salary and status, but will be tied to a person's family relationships. Twenty years ago, most managers were not concerned with the family problems of their subordinates. This notion is now out of date. The family responsibilities of staff have a direct effect on the company's productivity. An employee who is worried about the care of an elderly parent, or concerned with the safety of a preteen home alone after school, is unlikely to give full attention to the task at hand. Flexible management is a cost-effective way of dealing with these issues. Managers who have the skills to be flexible and the strategies to work with employees for a win-win situation will reduce distractions and tardiness and gain productivity and loyalty.

    Weindl, Isabelle; Lotze-Campen, Hermann; Popp, Alexander; Müller, Christoph; Schmitz, Christoph; Rolinski, Susanne; Havlík, Petr; Herrero, Mario

    2015-01-01

    Livestock farming is the world’s largest land use sector and utilizes around 60% of the global biomass harvest. Over the coming decades, climate change will affect the natural resource base of livestock production, especially the productivity of rangeland and feed crops. Based on a comprehensive impact modeling chain, we assess implications of different climate projections for agricultural production costs and land use change and explore the effectiveness of livestock system transitions as an adaptation strategy. Simulated climate impacts on crop yields and rangeland productivity generate adaptation costs amounting to 3% of total agricultural production costs in 2045 (i.e. 145 billion US$). Shifts in livestock production towards mixed crop-livestock systems represent a resource- and cost-efficient adaptation option, reducing agricultural adaptation costs to 0.3% of total production costs and simultaneously abating deforestation by about 76 million ha globally. The relatively positive climate impacts on grass yields compared with crop yields favor grazing systems inter alia in South Asia and North America. Incomplete transitions in production systems already have a strong adaptive and cost reducing effect: a 50% shift to mixed systems lowers agricultural adaptation costs to 0.8%. General responses of production costs to system transitions are robust across different global climate and crop models as well as regarding assumptions on CO 2 fertilization, but simulated values show a large variation. In the face of these uncertainties, public policy support for transforming livestock production systems provides an important lever to improve agricultural resource management and lower adaptation costs, possibly even contributing to emission reduction.

    1992-04-01

    The project initiated by the United Nations Environment Programme aims to clarify some economic issues involved in greenhouse gas limitation by carrying out comparative studies of various nations. The programme should contribute to the establishment of a consistent methodological framework for making cost assessments of greenhouse gas abatement and help to support countries in the process of establishing national and international agreements on actions to combat climate change. The publication gives a survey of Danish energy demand and supply, emissions and current energy policy issues and reviews existing studies of carbon dioxide reductions. This includes the overall national environmental policy and the plan of action for the transport sector. Conclusions are that there seems to be a long-term potential for significant reduction of CO 2 emission by 10-15% by 2010 with no additional costs, a 50% reduction will cost DKK 25-50 per kg reduced CO 2 . The most promising options include increased use of cogeneration of heat and electricity, and electricity conservation in households, services and in industry. Economic growth is forecast as ca. 2.7% and energy prices for oil products should increase by ca. 4.8%. A 40% reduction of CO 2 emission in the year 2005 would increase costs by 1-2%, and a reduction of two thirds of present emission should be possible at no additional cost compared to the reference cases. There is general agreement that a reduction of carbon dioxide emission of 15-30% by 2005-10 should involve no additional costs to society. (AB) (11 refs.)

  17. Marginal abatement cost curves for policy recommendation – A method for energy system analysis

    Tomaschek, Jan

    2015-01-01

    The transport sector is seen as one of the key factors for driving future energy consumption and greenhouse gas (GHG) emissions. In order to rank possible measures marginal abatement cost curves have become a tool to graphically represent the relationship between abatement costs and emission reduction. This paper demonstrates how to derive marginal abatement cost curves for well-to-wheel GHG emissions of the transport sector considering the full energy provision chain and the interlinkages and interdependencies within the energy system. Presented marginal abatement cost curves visualize substitution effects between measures for different marginal mitigation costs. The analysis makes use of an application of the energy system model generator TIMES for South Africa (TIMES-GEECO). For the example of Gauteng province, this study exemplary shows that the transport sector is not the first sector to address for cost-efficient reduction of GHG emissions. However, the analysis also demonstrates that several options are available to mitigate transport related GHG emissions at comparable low marginal abatement costs. This methodology can be transferred to other economic sectors as well as to other regions in the world to derive cost-efficient GHG reduction strategies

  18. Infectious disease risk in asbestos abatement workers.

    Lange, John H; Mastrangelo, Giuseppe; Cegolon, Luca

    2012-08-16

    The current literature reports increased infectious disease occurrence in various construction occupations, as an important contributor to morbidity and mortality arising from employment.These observations should be expanded to asbestos abatement workers, as the abatement can create an environment favorable for bacterial, viral and fungal infections. Asbestos abatement work employs activities resulting in cuts, blisters and abrasions to the skin, work in a dirty environment and exposure to dust, mists and fumes.Furthermore, this population exhibits a high smoking rate which increases the risk of chronic obstructive pulmonary disease and respiratory infections.In addition, these workers also commonly employ respirators, which can accumulate dirt and debris magnifying exposure to microbes. Use of respirators and related types of personal protective equipment, especially if shared and in the close environment experienced by workers, may enhance communicability of these agents, including viruses. Abatement workers need to be provided with information on hazards and targeted by appropriate health education to reduce the infection risk. Epidemiological studies to investigate this risk in asbestos removers are recommended.

    2010-01-01

    This book expresses the French State's view on the way to deal with the issue of climate change adaptation. After having recalled the ineluctability of some observed changes, the actors involved in this adaptation, and some guideline principles to implement adaptation, a first chapter describes the context: international mobilization, climate data evolution, definition of new criteria and critical thresholds, relationship between adaptation, alleviation and sustainable development, tensions between long and short terms. It discusses the objectives: public security and health, alleviation of inequalities with respect to risks, cost reduction, natural heritage preservation. Nine strategic axes are then identified: to develop knowledge, to strengthen the survey system, to inform, to educate and to make all actors aware, to promote a territory-based approach, to finance adaptation actions, to use regulatory and law instruments, to support voluntary approaches and the dialogue with private actors, to take the overseas peculiarity into account, and to contribute to international exchanges. The next chapters are respectively dealing with transverse approaches (water, risk prevention, health, and biodiversity), sector-based insights (agriculture, energy and industry, transports, building and housing, tourism, banks and insurance companies), medium-based approach (cities, littoral and seas, mountain, forest). The last part deals with the implementation issue

  8. Strategies facilitating practice change in pediatric cancer: a systematic review.

    Robinson, Paula D; Dupuis, Lee L; Tomlinson, George; Phillips, Bob; Greenberg, Mark; Sung, Lillian

    2016-09-01

    By conducting a systematic review, we describe strategies to actively disseminate knowledge or facilitate practice change among healthcare providers caring for children with cancer and we evaluate the effectiveness of these strategies. We searched Ovid Medline, EMBASE and PsychINFO. Fully published primary studies were included if they evaluated one or more professional intervention strategies to actively disseminate knowledge or facilitate practice change in pediatric cancer or hematopoietic stem cell transplantation. Data extracted included study characteristics and strategies evaluated. In studies with a quantitative analysis of patient outcomes, the relationship between study-level characteristics and statistically significant primary analyses was evaluated. Of 20 644 titles and abstracts screened, 146 studies were retrieved in full and 60 were included. In 20 studies, quantitative evaluation of patient outcomes was examined and a primary outcome was stated. Eighteen studies were 'before and after' design; there were no randomized studies. All studies were at risk for bias. Interrupted time series was never the primary analytic approach. No specific strategy type was successful at improving patient outcomes. Literature describing strategies to facilitate practice change in pediatric cancer is emerging. However, major methodological limitations exist. Studies with robust designs are required to identify effective strategies to effect practice change. © The Author 2016.

  9. Hanford Tank Farm Vapors Abatement Technology and Vendor Proposals Assessment

    Burns, H. H.; Farrar, M. E.; Fink, S. D.

    2016-01-01

    Suspected chemical vapor releases from the Hanford nuclear waste tank system pose concerns for worker exposure. Washington River Protection Solutions (WRPS) contracted the Savannah River National Laboratory (SRNL) to explore abatement technologies and strategies to remediate the vapors emitted through the ventilation system. In response, SRNL conducted an evaluation of technologies to abate, or reduce, vapor emissions to below 10% of the recognized occupational exposure limits (OELs). The evaluation included a review of published literature and a broadly communicated Request for Information to commercial vendors through a Federal Business Opportunities (Fed Biz Opps) web posting. In addition, SRNL conducted a workshop and post-workshop conference calls with interested suppliers (vendors) to assess proposals of relevant technologies. This report reviews applicable technologies and summarizes the approaches proposed by the vendors who participated in the workshop and teleconference interviews. In addition, the report evaluates the estimated performance of the individual technologies for the various classes of chemical compounds present in the Hanford Chemicals of Potential Concern (COPCs) list. Similarly, the report provides a relative evaluation of the vendor proposed approaches against criteria of: technical feasibility (and maturity), design features, operational considerations, secondary waste generation, safety/regulatory, and cost / schedule. These rough order-of-magnitude (ROM) cost estimates are intended to provide a comparison basis between technologies and are not intended to be actual project estimates.

  11. Emission abatement: Untangling the impacts of the EU ETS and the economic crisis

    Bel, Germà; Joseph, Stephan

    2015-01-01

    In this study we use historical emission data from installations under the European Union Emissions Trading System (EU ETS) to evaluate the impact of this policy on greenhouse gas emissions during the first two trading phases (2005–2012). As such the analysis seeks to disentangle two causes of emission abatement: that attributable to the EU ETS and that attributable to the economic crisis that hit the EU in 2008/09. To do so, we use a dynamic panel data approach. Our results suggest that, by far, the biggest share of abatement was attributable to the effects of the economic crisis. This finding has serious implications for future policy adjustments affecting core elements of the EU ETS, including the distribution of EU emission allowances. - Highlights: • We untangle the effects of the EU ETS from those of the economic crisis on industrial emission abatement. • The empirical analysis uses verified emission data instead of estimated emission data. • Abatement of emissions in EU in the last years has been mainly due to the impact of the economic crisis. • Low level of abatement attributable to the EU ETS suggests that important changes must be made in environmental policy

  12. Dynamic optimal strategies in transboundary pollution game under learning by doing

    Chang, Shuhua; Qin, Weihua; Wang, Xinyu

    2018-01-01

    In this paper, we present a transboundary pollution game, in which emission permits trading and pollution abatement costs under learning by doing are considered. In this model, the abatement cost mainly depends on the level of pollution abatement and the experience of using pollution abatement technology. We use optimal control theory to investigate the optimal emission paths and the optimal pollution abatement strategies under cooperative and noncooperative games, respectively. Additionally, the effects of parameters on the results have been examined.

    -level governance strategies, could significantly augment the carbon abatement contributions of city actions toward national climate targets. The results suggest that cities may play a pivotal role in progress toward national climate targets. In addition to providing carbon and emissions estimates, this report estimates the national net economic impacts of policies for which cost and benefit data are available. Impact metrics include employment, worker earnings, and gross domestic product (GDP). For the policy areas studied, the economic analysis demonstrates that city carbon abatement may be achieved with only minimal and generally slightly positive economic impacts. Employment impacts range from 0.04% to 0.13% of U.S, employment during implementation and zero to 0.1% thereafter. GDP estimates show net impacts of 0.02% to 0.07% of GDP during implementation and impacts from -0.02% to zero thereafter. This report quantitatively demonstrates the material impact of a limited set of local policy areas on national carbon abatement potential. The magnitude of estimated carbon reductions from city policies, 3%-7% of national emissions by 2035, suggests an important role for city-led actions in reaching U.S. climate goals. Multi-level governance at the city, state, and national levels could augment the carbon abatement potential of city actions and make cities a key component of long-term U.S. climate strategies.

  19. Strategies for sustainable management of renewable resources during environmental change.

    Lindkvist, Emilie; Ekeberg, Örjan; Norberg, Jon

    2017-03-15

    As a consequence of global environmental change, management strategies that can deal with unexpected change in resource dynamics are becoming increasingly important. In this paper we undertake a novel approach to studying resource growth problems using a computational form of adaptive management to find optimal strategies for prevalent natural resource management dilemmas. We scrutinize adaptive management, or learning-by-doing, to better understand how to simultaneously manage and learn about a system when its dynamics are unknown. We study important trade-offs in decision-making with respect to choosing optimal actions (harvest efforts) for sustainable management during change. This is operationalized through an artificially intelligent model where we analyze how different trends and fluctuations in growth rates of a renewable resource affect the performance of different management strategies. Our results show that the optimal strategy for managing resources with declining growth is capable of managing resources with fluctuating or increasing growth at a negligible cost, creating in a management strategy that is both efficient and robust towards future unknown changes. To obtain this strategy, adaptive management should strive for: high learning rates to new knowledge, high valuation of future outcomes and modest exploration around what is perceived as the optimal action. © 2017 The Author(s).

    It is now well established that the emission of sub-micrometric particulate matter entrained in flue gases of industry and vehicles exhausts, is one of the most critical treats for human health because of the toxicological effects of ultrafine particles on the respiratory system and their ability to cross alveoli’s membranes reaching the circulatory system too. Albeit this scenario, the traditional particle abatement devices are mainly designed and optimised to treat particles larger tha...

  1. Human health risks associated with asbestos abatement.

    Chrostowski, P C; Foster, S A; Anderson, E L

    1991-09-01

    Upperbound lifetime excess cancer risks were calculated for activities associated with asbestos abatement using a risk assessment framework developed for EPA's Superfund program. It was found that removals were associated with cancer risks to workers which were often greater than the commonly accepted cancer risk of 1 x 10(-6), although lower than occupational exposure limits associated with risks of 1 x 10(-3). Removals had little effect in reducing risk to school populations. Risks to teachers and students in school buildings containing asbestos were approximately the same as risks associated with exposure to ambient asbestos by the general public and were below the levels typically of concern to regulatory agencies. During abatement, however, there were increased risks to both workers and nearby individuals. Careless, everyday building maintenance generated the greatest risk to workers followed by removals and encapsulation. If asbestos abatement was judged by the risk criteria applied to EPA's Superfund program, the no-action alternative would likely be selected in preference to removal in a majority of cases. These conclusions should only be interpreted within the context of an overall asbestos risk management program, which includes consideration of specific fiber types and sizes, sampling and analytical limitations, physical condition of asbestos-containing material, episodic peak exposures, and the number of people potentially exposed.

  2. Using goal setting as a strategy for dietary behavior change.

    Cullen, K W; Baranowski, T; Smith, S P

    2001-05-01

    Recent reviews have noted that behavioral theory-based nutrition education programs are more successful at achieving food behavior change than knowledge-based programs and that a clear understanding of the mechanisms of behavior change procedures enable dietetics professionals to more effectively promote change. Successful dietary behavior change programs target 1 or more of the personal, behavioral, or environmental factors that influence the behavior of interest and apply theory-based strategies to influence or change those factors. Goal setting is a strategy that is frequently used to help people change. A 4-step goal-setting process has been identified: recognizing a need for change; establishing a goal; adopting a goal-directed activity and self-monitoring it; and self-rewarding goal attainment. The applications of goal setting in dietary interventions for adults and children are reviewed here. Because interventions using goal setting appear to promote dietary change, dietitians should consider incorporating the goal-setting strategies to enhance the behavior change process in nutrition education programs.

    2016-03-01

    Full Text Available Purpose: On the topic of sustainable aviation a study was carried out to measure the difference between the actual change in air traffic noise and the airport’s residents’ perception of the noise change at Vienna International Airport. Therefore, a questionnaire was developed in cooperation with the airport and an online survey was conducted. Design/methodology/approach: For the survey of the opinion of the affected population of the surrounding communities, a web based online questionnaire is created and distributed via various channels including e-mail, and online forums. After the basic structure of the questionnaire had been defined, the questions were developed in cooperation with employees form the environmental department of VIE, who had a sustainable influence on the questions’ order and formulation. As the survey was supposed to be answered by residents around VIE. Findings: Results of the online study show that only parts of the participants are affected by air traffic noise at VIE. Even less experienced a significant change over the last five years. About one third of the participants stated that they are affected by air traffic noise in one way or another. The majority of these people live in Lower Austria, the federal state in which the airport is located. The participants obviously judge air traffic noise during day time more importantly than air traffic noise at night. Research limitations/implications: Due to the low number of returns, no statistically relevant conclusions can be drawn, the results of the survey can be used to make some general statements. Originality/value: Economic growth and deregulation lead to growing aircraft operations. Vienna International Airport with its approximately 260,000 flight movements per year is the biggest airport in Austria and a major hub in Europe. The combination of constantly growing air transport and the resulting noise exposure, as well as the steadily increasing

  7. Change in MSW characteristics under recent management strategies in Taiwan.

    Chang, Yu-Min; Liu, Chien-Chung; Hung, Chao-Yang; Hu, Allen; Chen, Shiao-Shing

    2008-12-01

    Reduction and recycling initiatives such as producer responsibility and pay-as-you-throw are being implemented in Taiwan. This paper presents a study assessing the impact of recently implemented municipal solid waste (MSW) reduction and recycling management strategies on the characteristics of waste feedstock for incineration in Taiwan. Through the periodic sampling of two typical MSW incineration plants, proximate and ultimate analyses were conducted according to standard methods to explore the influence of MSW reduction and recycling management strategies on incineration feed waste characteristics. It was observed that the annual amount of MSW generated in 2005 decreased by about 10% compared to 2003 and that the characteristics of MSW have changed significantly due to recent management strategies. The heating value of the MSW generated in Taiwan increased yearly by about 5% after program implementation. A comparison of the monthly variations in chemical concentrations indicated that the chlorine content in MSW has changed. This change results from usage reduction of PVC plastic due to the recycling fund management (RFM) program, and the food waste as well as salt content reduction due to the total recycling for kitchen garbage program. This achievement will improve the reduction of dioxin emissions from MSW incineration. In summary, management strategies must be conducted in tandem with the global trend to achieve a zero-waste-discharge country. When implementing these strategies and planning for future MSW management systems, it is important to consider the changes that may occur in the composition and characteristics of MSW over time.

  8. Managing strategic change--strategy, culture and action.

    1992-02-01

    One of the major problems facing senior executives is that of effecting significant strategic change in their organizations. This paper develops a number of explanatory frameworks which address the links between the development of strategy in organizations, dimensions of corporate culture and managerial action. In considering such linkages, and by illustrating them with examples from work undertaken in companies, the paper also seeks to advance our understanding of the problems and means of managing strategic change.

  9. Changes in hospital competitive strategy: a new medical arms race?

    Devers, Kelly J; Brewster, Linda R; Casalino, Lawrence P

    2003-02-01

    To describe changes in hospitals' competitive strategies, specifically the relative emphasis placed on strategies for competing along price and nonprice (i.e., service, amenities, perceived quality) dimensions, and the reasons for any observed shifts. This study uses data gathered through the Community Tracking Study site visits, a longitudinal study of a nationally representative sample of 12 U.S. communities. Research teams visited each of these communities every two years since 1996 and conducted between 50 to 90 semistructured interviews. Additional information on hospital competition and strategy was gathered from secondary data. We found that hospitals' strategic emphasis changed significantly between 1996-1997 and 2000-2001. In the mid-1990s, hospitals primarily competed on price through "wholesale" strategies (i.e., providing services attractive to managed care plans). By 2000-2001, nonprice competition was becoming increasingly important and hospitals were reviving "retail" strategies (i.e., providing services attractive to individual physicians and the patients they serve). Three major factors explain this shift in hospital strategy: less than anticipated selective contracting and capitated payment; the freeing up of hospital resources previously devoted to horizontal and vertical integration strategies; and, the emergence and growth of new competitors. Renewed emphasis on nonprice competition and retail strategies, and the service mimicking and one-upmanship that result, suggest that a new medical arms race is emerging. However, there are important differences between the medical arms race today and the one that occurred in the 1970s and early 1980s: the hospital market is more concentrated and price competition remains relatively important. The development of a new medical arms race has significant research and policy implications.

  12. The oil industry and climate change: strategies and ethical dilemmas

    Hove, S. van den; Le Menestrel, M.; Bettignies, H.C. de

    2002-01-01

    This paper explores the different climate change strategies chosen by three major multinational oil corporations: ExxonMobil, TotalFinaElf and BP Amoco. They are referred to, as the 'fight against emission constraints,' 'wait and see,' and 'proactive' strategies, respectively. The justifications given to support these strategies are identified. They cover the business, scientific, political, economic, technological and social dimensions. In a business ethics framework, the issue of climate change brings forth an ethical dilemma for the oil industry, in the form of a tension between profits and CO 2 emissions. The strategies are analysed as three attitudes towards this dilemma: (i) placing priority on the business consequences while weakening the perception that anthropogenic greenhouse gas emissions are causing climate change; (ii) avoiding responsibility; and (iii) placing priority on the need for a modification of the business process while limiting the negative effect in terms of business consequences. In conclusion, we propose that beyond the ethical issues proper to climate change itself, additional ethical issues are raised if society at large is instrumentalised by an industry in its search for profit. Publicly gauging and valorising the ethical commitment of a corporation appear as ways of inducing more collaborative and proactive attitudes by business actors. (Author)

  15. An evaluation of the effect of greenhouse gas accounting methods on a marginal abatement cost curve for Irish agricultural greenhouse gas emissions

    O’Brien, Donal; Shalloo, Laurence; Crosson, Paul; Donnellan, Trevor; Farrelly, Niall; Finnan, John; Hanrahan, Kevin; Lalor, Stan; Lanigan, Gary; Thorne, Fiona; Schulte, Rogier

    2014-01-01

    Highlights: • Improving productivity was the most effective strategy to reduce emissions and costs. • The accounting methods disagreed on the total abatement potential of mitigation measures. • Thus, it may be difficult to convince farmers to adopt certain abatement measures. • Domestic offsetting and consumption based accounting are options to overcome current methodological issues. - Abstract: Marginal abatement cost curve (MACC) analysis allows the evaluation of strategies to reduce agricultural greenhouse gas (GHG) emissions relative to some reference scenario and encompasses their costs or benefits. A popular approach to quantify the potential to abate national agricultural emissions is the Intergovernmental Panel on Climate Change guidelines for national GHG inventories (IPCC-NI method). This methodology is the standard for assessing compliance with binding national GHG reduction targets and uses a sector based framework to attribute emissions. There is however an alternative to the IPCC-NI method, known as life cycle assessment (LCA), which is the preferred method to assess the GHG intensity of food production (kg of GHG/unit of food). The purpose of this study was to compare the effect of using the IPCC-NI and LCA methodologies when completing a MACC analysis of national agricultural GHG emissions. The MACC was applied to the Irish agricultural sector and mitigation measures were only constrained by the biophysical environment. The reference scenario chosen assumed that the 2020 growth targets set by the Irish agricultural industry would be achieved. The comparison of methodologies showed that only 1.1 Mt of the annual GHG abatement potential that can be achieved at zero or negative cost could be attributed to agricultural sector using the IPCC-NI method, which was only 44% of the zero or negative cost abatement potential attributed to the sector using the LCA method. The difference between methodologies was because the IPCC-NI method attributes the

  16. Porter's generic strategies, discontinuous environments, and performance: a longitudinal study of changing strategies in the hospital industry.

    Lamont, B T; Marlin, D; Hoffman, J J

    1993-12-01

    Changes in generic strategies in response to discontinuous environments have been relatively ignored in the management literature. This study reports an examination of the relationships between Porter's (1980) generic strategies, discontinuous environments, and performance. Archival data for 1984 and 1988 were collected for 172 acute care hospitals in Florida in order to test these relationships. To examine fully the performance impact of changes in strategy in a discontinuous environment, a longitudinal research design that identified a firm's strategy at two points in time, 1984 and 1988, was used. Results indicate that firms with a proper strategy environment fit performed the highest, firms that did not change their strategy had no change in performance, and firms that changed their strategy toward a proper strategy environment showed an increase in performance. Findings support the notion that hospitals with appropriate strategy-environment combinations will exhibit higher performance.

    2008-05-15

    This paper introduces a solution for the fair division of emission reduction costs in the climate change regime. Our primary focus is on the fair division of efficiency gains that arise from exchanging the initial allocation of emission entitlements, rather than the initial allocation itself. We propose to complement the competitive Walrasian solution with welfare bounds, the ethical justification of which rests on commonality of ownership. Simulations with an intertemporal computable general equilibrium model illustrate the relevance of such welfare bounds. For a wide range of initial allocations of emission entitlements - including an equal per capita allocation - we find that developing countries should be fully compensated for their emission abatement efforts, but should not receive any further transfers.

  19. Business Responses to Climate Change. Identifying Emergent Strategies

    Kolk, A.; Pinkse, J.

    2005-01-01

    Companies face much uncertainty about the competitive effects of the recently adopted Kyoto Protocol on global climate change and the current and future regulations that may emerge from it. Companies have considerable discretion to explore different market strategies to address global warming and reduce greenhouse gas emissions. This article examines these strategic options by reviewing the market-oriented actions that are currently being taken by 136 large companies that are part of the Global 500. There are six different market strategies that companies use to address climate change and that consist of different combinations of the market components available to managers. Managers can choose between more emphasis on improvements in their business activities through innovation or employ compensatory approaches such as emissions trading. They can either act by themselves or work with other companies, NGOs, or (local) governments

  2. Cognitive debiasing 2: impediments to and strategies for change.

    Croskerry, Pat; Singhal, Geeta; Mamede, Sílvia

    2013-10-01

    In a companion paper, we proposed that cognitive debiasing is a skill essential in developing sound clinical reasoning to mitigate the incidence of diagnostic failure. We reviewed the origins of cognitive biases and some proposed mechanisms for how debiasing processes might work. In this paper, we first outline a general schema of how cognitive change occurs and the constraints that may apply. We review a variety of individual factors, many of them biases themselves, which may be impediments to change. We then examine the major strategies that have been developed in the social sciences and in medicine to achieve cognitive and affective debiasing, including the important concept of forcing functions. The abundance and rich variety of approaches that exist in the literature and in individual clinical domains illustrate the difficulties inherent in achieving cognitive change, and also the need for such interventions. Ongoing cognitive debiasing is arguably the most important feature of the critical thinker and the well-calibrated mind. We outline three groups of suggested interventions going forward: educational strategies, workplace strategies and forcing functions. We stress the importance of ambient and contextual influences on the quality of individual decision making and the need to address factors known to impair calibration of the decision maker. We also emphasise the importance of introducing these concepts and corollary development of training in critical thinking in the undergraduate level in medical education.

  3. Legitimately seeking differences: The case of climate change strategies

    Bui, B.; Fowler, C. [Victoria Univ. of Wellington (New Zealand)

    2009-07-01

    In 2002, the New Zealand Government announced its intention to introduce a carbon tax as part of its response to climate change. Following the review of New Zealand climate change policies, the proposed carbon tax was ruled out in 2005 and other measures were investigated. In October 2007, the government announced its new climate change policy package, a fundamental part of which is the domestic cap-and-trade Emissions Trading Scheme (ETS). The scheme is currently being revised by the Government, with a report due August 2009. The government's climate change policy and the ETS in particular, represent significant changes in regulatory and societal expectations of the way in which businesses will account for the impact of their carbon emissions on the natural environment. The New Zealand electricity generators are among the most heavily impacted by the Government's climate change policy due to the scale of carbon emissions from electricity generation. This study utilizes institutional theory and the concept of legitimate differentiation, using a resource-based view, to examine and explain the changes in the electricity generators' carbon-strategy related environmental management and reporting practices as a result of regulatory, societal and financial pressures arising from the Government's climate change policy as it changed between 2002 and 2008. A study of organizations' reactions to climate change regulations is timely because the phenomenon of changing regulation is worldwide and far-reaching in scale. As such, the findings from a New Zealand study of electricity companies are releavant to many countries and organizations. Two generators that are among the firms with highest levels of carbon emissions in the New Zealand electricity industry (NZEI) are selected for in-depth analysis. Each company is first analyzed longitudinally (2001-2008) to discern changes in their internal environmental structures, systems and strategies to account

  4. A review of Thailand's strategies for global climate change

    Boonchalermkit, S.

    1994-01-01

    Thailand is greatly concerned about global climate change, which is caused primarily by the burning of fossil fuels, deforestation and the release of chlorofluorocarbons. The country itself is not currently a major contributor to global climate change. However, as Thailand's economy expands and its burning of fossil fuels increases, the country's contribution to global climate change could increase. Thailand's use of primary energy supplies grew at an average rate of 13.4 percent per year in the period 1985 to 1990. The rapid, sustained growth was due to the overall pace of growth in the economy and the expansion of industrial, construction, and transportation activities. The primary energy demand was approximately 31,600 kilotons of oil equivalent (KTOE) in 1990. The transportation sector accounted for the largest proportion of energy demand at 30 percent. Within the next 15 years, the power sector is expected to overtake the transportation sector as the largest consumer of energy. Petroleum is currently the predominant source of energy in Thailand, accounting for 56 percent of the primary energy demand. Thailand recognizes that it has an important part to play in finding solutions to minimizing emissions of greenhouse gases and identifying viable response strategies. Thus, in this paper the authors will present several policy strategies relevant to climate change in Thailand and discuss how they have been implemented and enforced. Policies concerning forestry, energy, and environment are reviewed in detail in this paper

  5. Terrestrial ecosystem responses to global change: A research strategy

    NONE

    1998-09-01

    Uncertainty about the magnitude of global change effects on terrestrial ecosystems and consequent feedbacks to the atmosphere impedes sound policy planning at regional, national, and global scales. A strategy to reduce these uncertainties must include a substantial increase in funding for large-scale ecosystem experiments and a careful prioritization of research efforts. Prioritization criteria should be based on the magnitude of potential changes in environmental properties of concern to society, including productivity; biodiversity; the storage and cycling of carbon, water, and nutrients; and sensitivity of specific ecosystems to environmental change. A research strategy is proposed that builds on existing knowledge of ecosystem responses to global change by (1) expanding the spatial and temporal scale of experimental ecosystem manipulations to include processes known to occur at large scales and over long time periods; (2) quantifying poorly understood linkages among processes through the use of experiments that manipulate multiple interacting environmental factors over a broader range of relevant conditions than did past experiments; and (3) prioritizing ecosystems for major experimental manipulations on the basis of potential positive and negative impacts on ecosystem properties and processes of intrinsic and/or utilitarian value to humans and on feedbacks of terrestrial ecosystems to the atmosphere.

  6. NOx Abatement Pilot Plant 90-day test results report

    McCray, J.A.; Boardman, R.D.

    1991-01-01

    High-level radioactive liquid wastes produced during nuclear fuel reprocessing at the Idaho Chemical Processing Plant are calcined in the New Waste Calcining Facility (NWCF) to provide both volume reduction and a more stable waste form. Because a large component of the HLW is nitric acid, high levels of oxides of nitrogen (NO x ) are produced in the process and discharged to the environment via the calciner off-gas. The NO x abatement program is required by the new Fuel Processing Restoration (FPR) project permit to construct to reduce NO x emissions from the NWCF. Extensive research and development has indicated that the selective catalytic reduction (SCR) process is the most promising technology for treating the NWCF off-gas. Pilot plant tests were performed to determine the compatibility of the SCR process with actual NWCF off-gas. Test results indicate that the SCR process is a viable method for abating the NO x from the NWCF off-gas. Reduction efficiencies over 95% can be obtained, with minimal amounts of ammonia slip, provided favorable operating conditions exist. Two reactors operated with series flow will provide optimum reduction capabilities. Typical operation should be performed with a first reactor stage gas space velocity of 20,000 hr -1 and an inlet temperature of 320 degrees C. The first stage exhaust NO x concentration will then dictate the parameter settings for the second stage. Operation should always strive for a peak reactor temperature of 520 degrees C in both reactors, with minimal NH 3 slip from the second reactor. Frequent fluctuations in the NWCF off-gas NO x concentration will require a full-scale reduction facility that is versatile and quick-responding. Sudden changes in NWCF off-gas NO x concentrations will require quick detection and immediate response to avoid reactor bed over-heating and/or excessive ammonia slip

  7. Cogeneration plant noise: Environmental impacts and abatement

    De Renzio, M.; Ciocca, B.

    1991-01-01

    In Italy, ever increasing attention to environmental problems has led to legislation requiring cogeneration plant owners to perform environmental impact assessments in order to determine plant conformity with pollution laws. This paper, based on an in-depth analysis of physics fundamentals relevant to the nature and effects of noise, examines the principal sources of noise in industrial cogeneration plants and the intensity and range of the effects of this noise on the local environment. A review is then made of the different methods of noise pollution abatement (e.g., heat and corrosion resistant silencers for gas turbines, varying types and thicknesses of acoustic insulation placed in specific locations) that can be effectively applied to cogeneration plant equipment and housing

  8. Application of cheaper materials in pollution abatement

    Hasany, S.M.

    1997-01-01

    Industrial effluents and waste water bearing toxic metal ions and hazardous organic substances including phenols and dyes need to be treated to remove such harmful materials before their safe disposal into biosphere. For this purpose a number of cheaper and waste materials like onion skin, bagasse pith, maize ob, groundnut husk, saw dust, wood, fugal and biomass, biogas waste slurry, lignite, wool fiber, fly ash, blast furnace sludge peat and charcoal, natural clays, sands and minerals, bone and glass have been used. some of these materials can also be employed to decontaminate fresh water containing these harmful substances present in very low concentrations. These cheaper materials have been reviewed and examples have been cited mostly from the recent literature. the optimal conditions for the removal of hazardous substances including metal ions form solutions utilizing these waste materials have also been given. These low cost materials have been proven to be very effective in the spheres of pollution abatement and environmental studies. (author)

  9. Energy and GHG abatement cost curves

    Alvarenga, Rafael [BHP Billiton Base Metals (Australia)

    2010-07-01

    Global warming due to various reasons but especially to emission of green house gases (GHGs) has become a cause for serious concern. This paper discusses the steps taken by BHP Billiton to reduce energy consumption and GHG emissions using cost curves. According to forecasts, global warming is expected to impact Chile badly and the rise in temperature could be between 1 and more than 5 degrees Celsius. Mining in Chile consumes a lot of energy, particularly electricity. Total energy and electricity consumption in 2007 was 13 and 36 % respectively. BHP base metals developed a set of abatement cost curves for energy and GHG in Chile and these are shown in figures. The methodology for the curves consisted of consultant visits to each mine operation. The study also includes mass energy balance and feasibility maps. The paper concludes that it is important to evaluate the potential for reducing emissions and energy and their associated costs.

  10. Behavioral Change Strategies for Improving Complementary Feeding and Breastfeeding.

    Osendarp, Saskia J M; Roche, Marion L

    2016-01-01

    Improving infant and young child feeding (IYCF) practices, including breastfeeding and complementary feeding, has been identified as one of the most effective interventions to improve child survival, stunting and wasting. Evidence from randomized controlled trials suggests that effective promotion of breastfeeding and complementary feeding, with or without food provision, has the potential to improve IYCF practices and child nutrition. However, in many countries, breastfeeding practices and complementary feeding practices are still far from optimal. The lack of implementation of available, effective, affordable interventions in scale-up programs is in part attributed to a lack of innovative, creative and effective behavioral change strategies that enable and encourage caregivers. Successful behavioral change strategies should be based on a rigorous situational analysis and formative research, and the findings and insights of formative research should be used to further design interventions that address the identified barriers and enablers, to select delivery channels, and to formulate appropriate and effective messages. In addition, successful behavioral change interventions should a priori define and investigate the program impact pathway to target behavioral change and should assess intermediary behavioral changes and indicators to learn why the expected outcome was achieved or not achieved by testing the program theory. The design of behavioral change communication must be flexible and responsive to shifts in societies and contexts. Performance of adequate IYCF also requires investments to generate community demand through social mobilization, relevant media and existing support systems. Applying these principles has been shown to be effective in improving IYCF practices in Vietnam, Bangladesh and Ethiopia and is recommended to be adopted by other programs and countries in order to accelerate progress in improving child nutrition. © 2016 S.

  11. R and D investment strategy for climate change

    Blanford, Geoffrey J.

    2009-01-01

    The economic costs of stabilizing greenhouse gas concentrations over the coming century depend critically on the development of new technologies in the energy sector. Our research and development (R and D) investment strategy is the control variable for technology availability. This paper proposes an analytic framework for determining optimal R and D investment allocation and presents some numerical results to demonstrate the implementation of the methodology. The value of technological advance in three targeted areas-fossil-based generation, renewables, and carbon capture and storage-is represented by the increase in expected welfare in the presence of an emissions policy constraint of initially uncertain stringency. R and D expenditure increases the probability of advance. Optimal investment is determined by its relationship with success probability, which is assumed to exhibit decreasing returns to scale, relative to the value of success. While the numerical results are speculative, the paper offers insights into the nature of an optimal technology strategy for addressing climate change. (author)

  12. Water Resources Research Program. Abatement of malodors at diked, dredged-material disposal sites. Final report

    Harrison, W.; Dravnieks, A.; Zussman, R.; Goltz, R.

    1976-06-01

    Samples of malodorous air and dredged material were collected at diked disposal sites at the following locations: Buffalo, NY; Milwaukee, WI; Mobile, AL; York Harbor, ME; Houston, TX; Detroit, MI; and Anacortes, WA; during the period July--October, 1975. Odorous compounds in the air samples were identified by gas chromatography/mass spectrometry, while the detection threshold, intensity, and character of the various odors were determined by experienced panelists using a dynamic, forced-choice-triangle olfactometer. Although significant problems with malodors were not observed beyond the disposal-area dikes during site visits, noteworthy odor episodes had occurred at some sites. An odor-abatement strategy is presented for handling the expected range of odor conditions at dredged-material disposal sites. Its aim is to reduce to an acceptable level the intensity of malodors in an affected community. The main steps in the strategy cover selection of the disposal site, site preparation, odor characterization of sediments to be dredged, malodor abatement during dredging and disposal operations, malodor abatement after filling of the disposal site, and the handling of malodor complaints.

    Full Text Available The objective of the study: to investigate the changes in preferable coping-strategies during treatment of the school-age children in a TB sanatorium. 77 patients (children and adolescents were enrolled into the study, they all had rehabilitation due to respiratory tuberculosis. All patients were divided into two groups: 8-12 years old (17 boys and 13 girls and 13-17 years old (24 boys and 23 girls. Coping strategies in the school-age children were investigated twice: at admission and discharge from the sanatorium, using a questionnaire adapted by N.A. Sirota and V.N. Yaltonsky and modified by R. M. Granovskaya and I.M. Nikolskaya. Analysis of the structure of the responses identified a group of patients who were oriented in the direction from the problem. This group presented a lower number of scores of the problem solution scale and a higher number of scores in the scales of avoidance, denial, fantasy formation. The other group of patients, focused in the direction towards the problem, characterized by a higher number of scores of the scales of problem solution and communication and a lower number of scores for the scales of denial and fantasy formation. Statistically significant changes were observed in the scale assessing communication (p = 0.03; there was a statistically significant reduction in the scores reflecting avoidance and denial (p < 0.001. There were no significant changes in the other scores.

  15. Optimal strategies for the abatement of gaseous air pollutant emissions produced by human mobility. The Rome case study; Strategie ottimali per la riduzione delle emissioni di inquinanti gassosi prodotte dalla mobilita' urbana. Un'applicazione al caso di Roma

    Santostefano, S.; Cirillo, M.C. [ENEA, Centro Ricerche Casaccia, Rome (Italy). Dipt. Ambiente

    1999-07-01

    In this paper a cost-effectiveness of gaseous vehicular emission reduction has been carried out for human mobility, over the transport network in Rome: in other words, once a reduction target of total emissions has been fixed for each pollutant, the most efficient abatement measures from a technical-economic point of view are selected. The optimization problem has been formalized considering linear functions both for the objective function and for constrains, i.e. within the classic linear programming framework, the objective being that of finding the diversion of present vehicular traffic to alternative technologies with lower emissions at minimum costs. A set of transport alternative measures has been considered and emission abatement cost minimization has been assumed as an objective function; specified abatements for CO (Carbon monoxide), NO{sub x} (nitrogen oxides) and VOC (Volatile Organic Compounds) emissions have been introduced as constraints to the problem, expressed as reduction rates of estimated present emissions in the considered area. Model results show the distribution of present transportation capacity among possible alternatives for different hypothesis of emission reduction rates (reduction of 25%, 50%, 75%, 85% of present emissions and maximum feasible reduction within the specified constraints), and related costs. [Italian] In questo rapporto e' stata condotta un'analisi costi-efficacia relativa alla riduzione delle emissioni gassose veicolari dovute alla mobilita' urbana sulla rete di trasporto di Roma: in altre parole, fissata una quota di abbattimento delle emissioni complessive per ogni inquinante, sono state individuate le misure piu' efficienti dal punto di vista tecnico-economico che permettono di perseguire la riduzione prefissata. Il problema di ottimizzazione e' stato formalizzato definendo sia la funzione obiettivo che i relativi vincoli come funzioni lineari, e quindi nell'ambito della programmazione

  17. Global climate change and the equity-efficiency puzzle

    Manne, Alan S.; Stephan, Gunter

    2005-01-01

    There is a broad consensus that the costs of abatement of global climate change can be reduced efficiently through the assignment of quota rights and through international trade in these rights. There is, however, no consensus on whether the initial assignment of emissions permits can affect the Pareto-optimal global level of abatement. This paper provides some insight into the equity-efficiency puzzle. Qualitative results are obtained from a small-scale model; then quantitative evidence of separability is obtained from MERGE, a multiregion integrated assessment model. It is shown that if all the costs of climate change can be expressed in terms of GDP losses, Pareto-efficient abatement strategies are independent of the initial allocation of emissions rights. This is the case sometimes described as 'market damages'. If, however, different regions assign different values to nonmarket damages such as species losses, different sharing rules may affect the Pareto-optimal level of greenhouse gas abatement. Separability may then be demonstrated only in specific cases (e.g. identical welfare functions or quasi-linearity of preferences or small shares of wealth devoted to abatement)

  18. Adaptation Strategies and Resilience to Climate Change of Historic Dwellings

    Carlos Rubio-Bellido

    2015-03-01

    Full Text Available Historic city centres have a large amount of dwellings in Europe, which were built to provide a comfortable shelter with the absence of mechanical means. The knowledge of climate responsive design strategies can play a significant role in reducing the energy demand of extant buildings, paving the way for its sustainable development in the face of the rising threat to its occupants of climate change. The residential architecture, developed, in most cases, in dense urban centres, was built using both available materials and traditional and academic construction technologies. This paper thoroughly investigates the extant urban conglomerate in Cádiz and analyses, in a qualitative and quantitative manner, which bioclimatic design strategies were applied and the city’s adaptation for future climate scenarios. The results indicate that historic housing in Cádiz is creatively adapted to the local natural conditions by means of a combination of climate responsive strategies, and there is significant scope for improvement in the ongoing response to global warming.

    1996-01-01

    A top executive for New England's biggest independent gas distributor says deregulation of the utility industry offers unprecedented opportunities for growth, but getting there will radically change the way it does business. To achieve dramatic growth, Bay State Gas Co. needs to base their strategies on anticipating the changes in the industry and aggressively positioning themselves to capture the new opportunities that the new business environment is creating. This includes: accelerating the unbundling of transportation service all the way to the residential customer level; forging strategic relationships with retail energy product and service companies as a means of increasing throughput on Bay State's system; implementing performance-based rates that provide financial incentives for lowering costs and improving customer service; accelerating the implementation of sophisticated information systems to streamline key business processes; and aggressively expanding Bay State's nonregulated Energy Products and Services business. These steps are discussed

  20. Change and Continuity in Indonesian Islamist Ideology and Terrorist Strategies

    Adam James Fenton

    2015-04-01

    Full Text Available The “Islamisation” of Indonesia has exerted a transformative force on every aspect of Indonesian society. That process continues today. It has created streams of change and continuity in thoughts, ideologies and practices, of enormous complexity. Strict doctrinal interpretation of Koranic text is not a new phenomenon, contrary to what some reports in the mass media might suggest. Its roots stretch back at least as far as the 1800s with the outbreak of violent conflicts between those urging a stricter, scripturalist application of Islam, and those adhering to traditionalist and colonialist ideologies --culminating in the Padri war of West Sumatra of 1821-38. Indicating an ostensible continuity of ideology, modern extremist ideologues, such as Abu Bakar Bashir, urge their followers toward violent conflict and terrorist actions based on an ideology of strict “Middle Eastern” interpretation of fundamental Islamic tenets. This paper argues that the strategies of those carrying out radical and violent ideologies are undergoing change, as are the strategies of the authorities tasked with combating them. Radical groups have displayed a shift away from large-scale, attacks on symbolic foreign targets towards low-level violence primarily aimed at law enforcement authorities. Authorities, on the other hand, have shown a greater tendency to shoot dead those suspected of involvement with violent radical groups. This paper will examine the changing strategies of violent radical groups and the continuity, and evolution, of the underlying Islamic ideology that provides religious justification for their violent acts. The paper will argue that engaging Indonesia’s politically active youth in an ideological dialogue on Islamism and democracy provides the best prospect for disengagement from, and breaking the cycle of recruitment for, radical violence and terrorism.[Proses panjang Islamisasi di Indonesia telah menghasilkan kekuatan transformatif di

  1. Task demands determine comparison strategy in whole probe change detection.

    Udale, Rob; Farrell, Simon; Kent, Chris

    2018-05-01

    Detecting a change in our visual world requires a process that compares the external environment (test display) with the contents of memory (study display). We addressed the question of whether people strategically adapt the comparison process in response to different decision loads. Study displays of 3 colored items were presented, followed by 'whole-display' probes containing 3 colored shapes. Participants were asked to decide whether any probed items contained a new feature. In Experiments 1-4, irrelevant changes to the probed item's locations or feature bindings influenced memory performance, suggesting that participants employed a comparison process that relied on spatial locations. This finding occurred irrespective of whether participants were asked to decide about the whole display, or only a single cued item within the display. In Experiment 5, when the base-rate of changes in the nonprobed items increased (increasing the incentive to use the cue effectively), participants were not influenced by irrelevant changes in location or feature bindings. In addition, we observed individual differences in the use of spatial cues. These results suggest that participants can flexibly switch between spatial and nonspatial comparison strategies, depending on interactions between individual differences and task demand factors. These findings have implications for models of visual working memory that assume that the comparison between study and test obligatorily relies on accessing visual features via their binding to location.

Researchers need to look at IT in different ways and suggest suitable solutions for practitioners.

  3. Advance strategy for climate change adaptation and mitigation in cities

    Varquez, A. C. G.; Kanda, M.; Darmanto, N. S.; Sueishi, T.; Kawano, N.

    2017-12-01

    An on-going 5-yr project financially supported by the Ministry of Environment, Japan, has been carried out to specifically address the issue of prescribing appropriate adaptation and mitigation measures to climate change in cities. Entitled "Case Study on Mitigation and Local Adaptation to Climate Change in an Asian Megacity, Jakarta", the project's relevant objectives is to develop a research framework that can consider both urbanization and climate change with the main advantage of being readily implementable for all cities around the world. The test location is the benchmark city, Jakarta, Indonesia, with the end focus of evaluating the benefits of various mitigation and adaptation strategies in Jakarta and other megacities. The framework was designed to improve representation of urban areas when conducting climate change investigations in cities; and to be able to quantify separately the impacts of urbanization and climate change to all cities globally. It is comprised of a sophisticated, top-down, multi-downscaling approach utilizing a regional model (numerical weather model) and a microscale model (energy balance model and CFD model), with global circulation models (GCM) as input. The models, except the GCM, were configured to reasonably consider land cover, urban morphology, and anthropogenic heating (AH). Equally as important, methodologies that can collect and estimate global distribution of urban parametric and AH datasets are continually being developed. Urban growth models, climate scenario matrices that match representative concentration pathways with shared socio-economic pathways, present distribution of socio-demographic indicators such as population and GDP, existing GIS datasets of urban parameters, are utilized. From these tools, future urbanization (urban morphological parameters and AH) can be introduced into the models. Sensitivity using various combinations of GCM and urbanization can be conducted. Furthermore, since the models utilize

  5. Risk management for sulfur dioxide abatement under multiple uncertainties

    Dai, C.; Sun, W.; Tan, Q.; Liu, Y.; Lu, W. T.; Guo, H. C.

    2016-03-01

    In this study, interval-parameter programming, two-stage stochastic programming (TSP), and conditional value-at-risk (CVaR) were incorporated into a general optimization framework, leading to an interval-parameter CVaR-based two-stage programming (ICTP) method. The ICTP method had several advantages: (i) its objective function simultaneously took expected cost and risk cost into consideration, and also used discrete random variables and discrete intervals to reflect uncertain properties; (ii) it quantitatively evaluated the right tail of distributions of random variables which could better calculate the risk of violated environmental standards; (iii) it was useful for helping decision makers to analyze the trade-offs between cost and risk; and (iv) it was effective to penalize the second-stage costs, as well as to capture the notion of risk in stochastic programming. The developed model was applied to sulfur dioxide abatement in an air quality management system. The results indicated that the ICTP method could be used for generating a series of air quality management schemes under different risk-aversion levels, for identifying desired air quality management strategies for decision makers, and for considering a proper balance between system economy and environmental quality.

  6. Sulfamethoxazole abatement by photo-Fenton

    Gonzalez, Oscar; Sans, Carme; Esplugas, Santiago

    2007-01-01

    The objective of this work was to study the abatement of 200 mg L -1 sulfamethoxazole (SMX) solution by means of photo-Fenton process. Biodegradability of the treated solutions was followed by the ratio biochemical oxygen demand at five days/chemical oxygen demand (BOD 5 /COD) and toxicity by Microtox[reg] and inhibition tests. Experiments with different initial concentration of H 2 O 2 were carried out. The initial amount of Fe 2+ and pH of the solution were set at 10 mg L -1 and 2.8 respectively. The temperature of the reactor was kept constant in all the experiments (25 ± 0.8 deg. C). Photo-Fenton process is thought to be a successful treatment step to improve the biodegradability of wastewater containing SMX. The complete antibiotic removal was achieved for a H 2 O 2 dose over 300 mg L -1 . Biodegradability (BOD 5 /COD) rose from zero (SMX solution) to values higher than 0.3 (treated solutions). Toxicity and inhibition tests pointed out in the same direction: oxidized intermediates for initial H 2 O 2 dose over 300 mg L -1 showed no toxicity effects on pure bacteria and no inhibition on activated sludge activity

    The UNEP (United Nations Environment Programme) programme of Greenhouse Gas Abatement Costing Studies is intended to clarify the economic issues involved in assessing the costs of limiting emissions of greenhouse gases and to propose approaches to comparable costing studies. Phase 1 of the Zimbabwe country study describes the current energy situation in Zimbabwe related to the national economy, energy supply and demand and amounts of greenhouse gas emissions.

    The UNEP (United Nations Environment Programme) programme of Greenhouse Gas Abatement Costing Studies is intended to clarify the economic issues involved in assessing the costs of limiting emissions of greenhouse gases and to propose approaches to comparable costing studies. Phase 1 of the Zimbabwe country study describes the current energy situation in Zimbabwe related to the national economy, energy supply and demand and amounts of greenhouse gas emissions. Factors regarding the geography, (including a map illustrating the degree and character of land degradation by erosion) population, politics, international relations, land-use and management of the energy sector are dealt with in detail and the text is illustrated with data compiled from the study. It is estimated that Zimbabwe consumed 270.4 Tj of energy during 1988 and emitted 21.7 tonnes of carbon dioxide.

    The aim was to assess options and cost of reducing emissions of greenhouse gases (with emphasis on carbon dioxide) from human activity in Zimbabwe. A brief description of the country's economy and energy sector, policy and pricing and regulations is given and substantial data related to the country's economy, technology, energy consumption, emission and fuel prices are presented. The energy demand in households and for other sectors in Zimbabwe are assessed, and documented in the case of the former. The reference scenarios on energy demand and supply assess greenhouse gas emissions under conditions whereby the present economic growth trends predominate. Energy efficiency improvements are discussed. Abatement technology options are stated as afforestation for carbon sequestration, more efficient coal-fired industrial boilers, extended use of hydroelectricity, prepayment electric meters, minimum tillage, optimization of coal-fired tobacco barns, industrial power factor correction equipment, domestic biogas digesters, solar water heating systems, time switches in electric geysers, optimization of industrial furnaces, photovoltaic water pumps, production of ammonia from coal for fertilizing purposes, and recovery of coke oven gases for use in thermal power generation.

  10. Managing organizational change: strategies for the female health care supervisor.

    Davies, G

    1990-07-01

    In responding to resistance to change in the current health care organization, the new female supervisor can learn to support her staff in encountering and accepting these changes. The strategies and skills discussed above are characteristic of a supervisory style that may naturally occur for women, but also can be incorporated into the leadership style of men in health care management today. Health care leaders of tomorrow must work from an androgynous framework in which the behavior patterns and responses of each gender are learned and used appropriately by both men and women. Sargent suggests that the best managers are androgynous and that this is the inevitable wave of the future. Whether man or woman, a supervisor should learn, accept, and use methods that are characteristic of both sexes to be successful in managing people. Women and men must learn from each other's strengths and share these diverse skills. Given that women now outnumber men in health care management positions and organizations are changing to a more nurturing environment, the androgynous supervisor will be the successful leader of the future. Finally, women in health care supervisory positions have the potential to bring change where it is badly needed. Women in these roles often have a system wide view of health care policy issues that recognizes less federal commitment to social programs. Many women in health care positions believe that the issues of children, women, the elderly, the poor, and the homeless need focused attention. The growing number of women in health care supervisory and leadership roles is an important factor in changing national health policy for the benefit of these groups.(ABSTRACT TRUNCATED AT 250 WORDS)

  11. Climate Change and Public Health Surveillance: Toward a Comprehensive Strategy.

    Moulton, Anthony Drummond; Schramm, Paul John

    Climate change poses a host of serious threats to human health that robust public health surveillance systems can help address. It is unknown, however, whether existing surveillance systems in the United States have adequate capacity to serve that role, nor what actions may be needed to develop adequate capacity. Our goals were to review efforts to assess and strengthen the capacity of public health surveillance systems to support health-related adaptation to climate change in the United States and to determine whether additional efforts are warranted. Building on frameworks issued by the Intergovernmental Panel on Climate Change and the Centers for Disease Control and Prevention, we specified 4 core components of public health surveillance capacity relevant to climate change health threats. Using standard methods, we next identified and analyzed multiple assessments of the existing, relevant capacity of public health surveillance systems as well as attempts to improve that capacity. We also received information from selected national public health associations. Multiple federal, state, and local public health agencies, professional associations, and researchers have made valuable, initial efforts to assess and strengthen surveillance capacity. These efforts, however, have been made by entities working independently and without the benefit of a shared conceptual framework or strategy. Their principal focus has been on identifying suitable indicators and data sources largely to the exclusion of other core components of surveillance capacity. A more comprehensive and strategic approach is needed to build the public health surveillance capacity required to protect the health of Americans in a world of rapidly evolving climate change. Public health practitioners and policy makers at all levels can use the findings and issues reviewed in this article as they lead design and execution of a coordinated, multisector strategic plan to create and sustain that capacity.

  13. Efficiency, equity or disagreement? The economics of international carbon abatement negotiations

    Mabey, N.; Smith, C.

    1995-01-01

    The current international effort to reduce greenhouse gas emissions, as embodied in the Framework Convention on Climate Change, is often criticized as inefficient by economists because it uses uniform targets instead of more theoretically efficient instruments such as international taxes. However, the effectiveness of any international treaty in producing environmental benefits is not wholly dependent on its economic efficiency but also on its political stability and the ability to accurately monitor and enforce its conditions. Stability depends on the magnitude and distribution of costs and benefits between countries which have heterogeneous economies, environmental damages, trading partners and abatement costs. The distribution of costs between countries will also depend on the type of policy instrument used to coordinate international abatement efforts. This paper analyses trade-offs that must be made when negotiating international agreements in order to balance the need for administrative convenience and economic efficiency with the realization that any agreement is better than no agreement

  14. CO2 Abatement In The Iron And Steel Industry

    NONE

    2012-01-15

    The iron and steel industry is the largest industrial source of CO2 emissions due to the energy intensity of steel production, its reliance on carbon-based fuels and reductants, and the large volume of steel produced -- over 1414 Mt in 2010. With the growing concern over climate change, steel makers are faced with the challenge of finding ways of lowering CO2 emissions without seriously undermining process efficiency or considerably adding to costs. This report examines ways of abating CO2 emissions from raw materials preparation (coking, sintering and pelletising plants) through to the production of liquid steel in basic oxygen furnaces and electric arc furnaces. Direct reduction and smelting reduction processes are covered, as well as iron making in a blast furnace. A range of technologies and measures exist for lowering CO2 emissions including minimising energy consumption and improving energy efficiency, changing to a fuel and/or reducing agent with a lower CO2 emission factor (such as wood charcoal), and capturing the CO2 and storing it underground. Significant CO2 reductions can be achieved by combining a number of the available technologies. If carbon capture and storage is fitted than steel plants could become near zero emitters of CO2.

  15. Adoption of Emissions Abating Technologies by U.S. Electricity Producing Firms Under the SO2 Emission Allowance Market

    Creamer, Gregorio Bernardo

    The objective of this research is to determine the adaptation strategies that coal-based, electricity producing firms in the United States utilize to comply with the emission control regulations imposed by the SO2 Emissions Allowance Market created by the Clean Air Act Amendment of 1990, and the effect of market conditions on the decision making process. In particular, I take into consideration (1) the existence of carbon contracts for the provision of coal that may a affect coal prices at the plant level, and (2) local and geographical conditions, as well as political arrangements that may encourage firms to adopt strategies that appear socially less efficient. As the electricity producing sector is a regulated sector, firms do not necessarily behave in a way that maximizes the welfare of society when reacting to environmental regulations. In other words, profit maximization actions taken by the firm do not necessarily translate into utility maximization for society. Therefore, the environmental regulator has to direct firms into adopting strategies that are socially efficient, i.e., that maximize utility. The SO 2 permit market is an instrument that allows each firm to reduce marginal emissions abatement costs according to their own production conditions and abatement costs. Companies will be driven to opt for a cost-minimizing emissions abatement strategy or a combination of abatement strategies when adapting to new environmental regulations or markets. Firms may adopt one or more of the following strategies to reduce abatement costs while meeting the emission constraints imposed by the SO2 Emissions Allowance Market: (1) continue with business as usual on the production site while buying SO2 permits to comply with environmental regulations, (2) switch to higher quality, lower sulfur coal inputs that will generate less SO2 emissions, or (3) adopting new emissions abating technologies. A utility optimization condition is that the marginal value of each input

  16. China's strategy for energy development and climate change mitigation

    He Jiankun; Yu Zhiwei; Zhang Da

    2012-01-01

    In recent years, China has made great efforts in energy saving and carbon emission reduction by pushing forward domestic sustainable development along with global climate change mitigation. The efforts have paid off with a dramatic decrease in carbon intensity. Nevertheless, China is still confronted with tough challenges in emission control due to the fast pace of industrialization, large total historical emission and high growth rate of emissions. Therefore, China should give priority to energy saving by improving energy efficiency and sectoral structure adjustment and upgrade, and develop sustainable and renewable energy to optimize energy mix and its carbon content. China should continue to regard significant reduction of energy intensity and carbon intensity as the main objective in the near future, strive to achieve peak emissions around 2030, and realize a relatively sharp emissions reduction by 2050 in order to address climate change to meet the goal of making the warming less than 2°. During the 12th Five Year Plan (FYP), China will further strengthen measures to control the amount of energy consumption, establish a statistics, accounting and evaluation system of carbon emissions, and promote a market-based carbon emissions trading mechanism to facilitate the low-carbon transformation of China's economy. - Highlights: ► This paper studies China's strategy for energy development and climate change mitigation. ► We suggest that China should focus on reducing the energy intensity and carbon intensity of GDP, and optimization of energy mix in the near term. ► In the long term, China should achieve the peak emission around 2030, and realize a relative sharp emission reduction by 2050. ► The paper also concludes some important measures which China should take during the 12th Five-Year-Plan (2011–2015).

  17. Multigas reduction strategy under climate stabilization target

    Kurosawa, A. [Inst. of Applied Energy, Tokyo (Japan)

    2005-07-01

    Global warming can be mitigated through the abatement of carbon dioxide (CO{sub 2}), methane (CH{sub 4}), nitrous oxide (N{sub 2}O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulfur hexafluoride (SF{sub 6}). This study argued that multiple gas reduction flexibility should be assessed when considering effective greenhouse gas (GHG) mitigation strategies. Emissions of non-CO{sub 2} GHGs were calculated endogenously using an integrated assessment model. Multigas reduction potential was measured in relation to long-term atmospheric temperature targets, and the effects on gas life as well as abatement timing uncertainty were considered in terms of cost and technological availability. The model consisted of 5 nodules which considered issues related to energy, climate, land use, macroeconomics, and environmental impacts. The time horizon of the model was 2000 to 2100. An economic utility maximization technology was used to consider global trade balances. Emissions of non-CO{sub 2} gases from specific sources was calculated by multiplying the emission factor and the endogenous parameters within the model. Results were presented for GHG emissions and concentrations in 2 simulation cases: (1) a no climate policy case (NCP); and (2) a transient temperature stabilization (TTS) case. Actions to reduce non-CO{sub 2} GHGs included activity level changes in production and consumption, and additional reductions in abatement costs without sector activity changes. Results of the study showed that reducing global dependency on fossil fuels was an effective way to reduce GHG effects from CO{sub 2}, CH{sub 4} and N{sub 2}O. Additional abatements to reduce N{sub 2}O emissions are required in the agricultural sector. Economic incentives and public outreach programs are needed to offset the high transaction costs of GHG mitigation strategies. It was concluded that both short-term and long-term policies are required to reduce GHG in all sectors. Multigas mitigation is needed to

  18. Estimating the financial risks of Andropogon gayanus to greenhouse gas abatement projects in northern Australia

    Adams, Vanessa M.; Setterfield, Samantha A.

    2013-06-01

    Financial mechanisms such as offsets are one strategy to abate greenhouse gas emissions, and the carbon market is expanding with a growing demand for offset products. However, in the case of carbon offsets, if the carbon is released due to intentional or unintentional reversal through environmental events such as fire, the financial liability to replace lost offsets will likely fall on the provider. This liability may have implications for future participation in programmes, but common strategies such as buffer pool and insurance products can be used to minimize this liability. In order for these strategies to be effective, an understanding of the spatial and temporal distributions of expected reversals is needed. We use the case study of savanna burning, an approved greenhouse gas abatement methodology under the Carbon Farming Initiative in Australia, to examine potential risks to carbon markets in northern Australia and quantify the financial risks. We focus our analysis on the threat of Andropogon gayanus (gamba grass) to savanna burning due to its documented impacts of increased fuel loads and altered fire regimes. We assess the spatial and financial extent to which gamba grass poses a risk to savanna burning programmes in northern Australia. We find that 75% of the eligible area for savanna burning is spatially coincident with the high suitability range for gamba grass. Our analysis demonstrates that the presence of gamba grass seriously impacts the financial viability of savanna burning projects. For example, in order to recuperate the annual costs of controlling 1 ha of gamba grass infestation, 290 ha of land must be enrolled in annual carbon abatement credits. Our results show an immediate need to contain gamba grass to its current extent to avoid future spread into large expanses of land, which are currently profitable for savanna burning.

  20. Terrestrial Ecosystem Responses to Global Change: A Research Strategy

    Ecosystems Working Group,

    1998-09-23

    Uncertainty about the magnitude of global change effects on terrestrial ecosystems and consequent feedbacks to the atmosphere impedes sound policy planning at regional, national, and global scales. A strategy to reduce these uncertainties must include a substantial increase in funding for large-scale ecosystem experiments and a careful prioritization of research efforts. Prioritization criteria should be based on the magnitude of potential changes in environmental properties of concern to society, including productivity; biodiversity; the storage and cycling of carbon, water, and nutrients; and sensitivity of specific ecosystems to environmental change. A research strategy is proposed that builds on existing knowledge of ecosystem responses to global change by (1) expanding the spatial and temporal scale of experimental ecosystem manipulations to include processes known to occur at large scales and over long time periods; (2) quantifying poorly understood linkages among processes through the use of experiments that manipulate multiple interacting environmental factors over a broader range of relevant conditions than did past experiments; and (3) prioritizing ecosystems for major experimental manipulations on the basis of potential positive and negative impacts on ecosystem properties and processes of intrinsic and/or utilitarian value to humans and on feedbacks of terrestrial ecosystems to the atmosphere. Models and experiments are equally important for developing process-level understanding into a predictive capability. To support both the development and testing of mechanistic ecosystem models, a two-tiered design of ecosystem experiments should be used. This design should include both (1) large-scale manipulative experiments for comprehensive testing of integrated ecosystem models and (2) multifactor, multilevel experiments for parameterization of process models across the critical range of interacting environmental factors (CO{sub 2}, temperature, water

  1. Commentary: one strategy for building public trust in changing times.

    Major health care reforms are being debated in the United States. While these debates address issues of access and cost, the systems-based problems of patient safety, continuous quality improvement, and an integrated approach to continuing professional development (CPD) remain traditional opportunities for the profession to directly improve health care and maintain professional accountability. Such challenges can be addressed independently of proposed reforms and offer an opportunity for the profession to build greater public trust. Given recent evidence questioning many assumptions behind individually focused CPD, and as physicians' work shifts into group and team contexts, it is an opportune time to address better CPD strategies within emerging group and team settings.The first strategic change requires a focus on managing the development of the individual physician's educational growth into a systems-oriented approach based on better information and feedback within groups of practitioners and health care teams. Second, the renewal of the linked visions of professional collegiality and accountability with professional regulation needs to be seen as a collective responsibility across key organizations within the profession's normal accountability framework. Thus, the professional colleges, certifying boards, and regulatory authorities need to collaborate with the CDP community in refocusing their collective activities to promote the profession's traditional role of improving the quality of care and maintaining the public's trust in these times of intense policy debate.

  2. Nitrate formation during ozonation as a surrogate parameter for abatement of micropollutants and the N-nitrosodimethylamine (NDMA) formation potential.

    Song, Yang; Breider, Florian; Ma, Jun; von Gunten, Urs

    2017-10-01

    In this study, nitrate formation from ammonium and/or dissolved organic nitrogen (DON) was investigated as a novel surrogate parameter to evaluate the abatement of micropollutants during ozonation of synthetic waters containing natural organic matter (NOM) isolates, a natural water and secondary wastewater effluents. Nitrate formation during ozonation was compared to the changes in UV absorbance at 254 nm (UVA 254 ) including the effect of pH. For low specific ozone doses UVA 254 was abated more efficiently than nitrate was formed. This is due to a relatively slow rate-limiting step for nitrate formation from the reaction between ozone and a proposed nitrogen-containing intermediate. This reaction cannot compete with the fast reactions between ozone and UV-absorbing moieties (e.g., activated aromatic compounds). To further test the kinetics of nitrate formation, two possible intermediates formed during ozonation of DON were tested. At pH 7, nitrate was formed during ozonation of acetone oxime and methyl nitroacetate with second-order rate constants of 256.7 ± 4.7 M -1  s -1 and 149.5 ± 5.8 M -1  s -1 , respectively. The abatement of the selected micropollutants (i.e., 17α-ethinylestradiol (EE2), carbamazepine (CBZ), bezafibrate (BZF), ibuprofen (IBU), and p-chlorobenzoic acid (pCBA)) was investigated for specific ozone doses ≤1.53 mgO 3 /mgDOC and its efficiency depended strongly on the reactivity of the selected compounds with ozone. The relative abatement of micropollutants (i.e., EE2 and CBZ) with high ozone reactivity showed linear relationships with nitrate formation. The abatement of micropollutants with intermediate-low ozone reactivity (BZF, IBU, and pCBA) followed one- and two-phase behaviors relative to nitrate formation during ozonation of water samples containing high and low concentrations of nitrate-forming DON, respectively. During ozonation of a wastewater sample, the N-nitrosodimethylamine formation potential (NDMA-FP) during

    2014-04-01

    The people who use Federal buildings — Federal employees, operations and maintenance staff, and the general public — can significantly impact a building’s environmental performance and the consumption of energy, water, and materials. Many factors influence building occupants’ use of resources (use behaviors) including work process requirements, ability to fulfill agency missions, new and possibly unfamiliar high-efficiency/high-performance building technologies; a lack of understanding, education, and training; inaccessible information or ineffective feedback mechanisms; and cultural norms and institutional rules and requirements, among others. While many strategies have been used to introduce new occupant use behaviors that promote sustainability and reduced resource consumption, few have been verified in the scientific literature or have properly documented case study results. This paper documents validated strategies that have been shown to encourage new use behaviors that can result in significant, persistent, and measureable reductions in resource consumption. From the peer-reviewed literature, the paper identifies relevant strategies for Federal facilities and commercial buildings that focus on the individual, groups of individuals (e.g., work groups), and institutions — their policies, requirements, and culture. The paper documents methods with evidence of success in changing use behaviors and enabling occupants to effectively interact with new technologies/designs. It also provides a case study of the strategies used at a Federal facility — Fort Carson, Colorado. The paper documents gaps in the current literature and approaches, and provides topics for future research.

  7. Chance-constrained/stochastic linear programming model for acid rain abatement. I. Complete colinearity and noncolinearity

    Ellis, J H; McBean, E A; Farquhar, G J

    1985-01-01

    A Linear Programming model is presented for development of acid rain abatement strategies in eastern North America. For a system comprised of 235 large controllable point sources and 83 uncontrolled area sources, it determines the least-cost method of reducing SO/sub 2/ emissions to satisfy maximum wet sulfur deposition limits at 20 sensitive receptor locations. In this paper, the purely deterministic model is extended to a probabilistic form by incorporating the effects of meteorologic variability on the long-range pollutant transport processes. These processes are represented by source-receptor-specific transfer coefficients. Experiments for quantifying the spatial variability of transfer coefficients showed their distributions to be approximately lognormal with logarithmic standard deviations consistently about unity. Three methods of incorporating second-moment random variable uncertainty into the deterministic LP framework are described: Two-Stage Programming Under Uncertainty, Chance-Constrained Programming and Stochastic Linear Programming. A composite CCP-SLP model is developed which embodies the two-dimensional characteristics of transfer coefficient uncertainty. Two probabilistic formulations are described involving complete colinearity and complete noncolinearity for the transfer coefficient covariance-correlation structure. The completely colinear and noncolinear formulations are considered extreme bounds in a meteorologic sense and yield abatement strategies of largely didactic value. Such strategies can be characterized as having excessive costs and undesirable deposition results in the completely colinear case and absence of a clearly defined system risk level (other than expected-value) in the noncolinear formulation.

  8. Future needs for ship emission abatement and technical measures

    Teresa ANTES

    2013-01-01

    Full Text Available The International Maritime Organization (IMO has revised air pollution regulations in MARPOL Annex VI. In 2012 Emission Control Areas (ECA will limit fuel sulphur content to 1% and from 2015 to 0.1%. NOx emissions based on ships engine speed are also reduced for new vessels (2012 & 2016. Facing this legislation, ship owners have the alternative either to operate ships with costly low-sulphur fuels, or to keep using HFO but together with a gas cleaning equipment at the ship stack in order to reduce the rejected amount of SO2 gas in the atmosphere. To achieve this requirement, research and development organizations came out with proposing a solution that uses a device for cleaning exhaust gas of marine diesel engines. The paper presents a short communication about the DEECON project, which aim is to create a novel on-board after-treatment unit more advanced than any currently available. Each sub-unit of the system will be optimized to remove a specific primary pollutant. In particular, the technology within the DEECON system is based on novel or improved abatement techniques for reducing SOx, NOx, Particulate Matter (PM, CO and Volatile Organic Compounds (VOC. Some of these technologies are completely new for the maritime sector and they will represent a breakthrough in the reduction of the atmospheric emissions of ships, moving forward the performance of exhaust gas cleaning systems and fostering and anticipating the adoption of future and tighter regulatory requirements. In addition, an after-treatment strategy enables the possible adoption of alternative fuels, which often have their own emissions characteristics.

  9. How to encourage road noise abatement in Nordic municipalities

    Sørensen, Claus Hedegaard

    2008-01-01

    Road noise nuisance is a huge problem in the Nordic countries, and it seems diffi cult for Nordic countries to meet national targets for its reduction. One reason for this is the lack of municipal activities in the fi eld. Th us the research question that this article seeks to answer in relation...... to already existing residential areas and roads is: which conditions in the municipal organisation and its institutional environment contribute to making municipalities provide and implement noise abatement measures? Th e assumption is that three factors infl uence how the municipalities prioritize among...... political issues: the municipal organisation itself, the local institutional environment (citizens, business and NGOs), and the state and trans-municipal networks. A study of the anatomy of municipal road noise abatement policy shows that conditions for implementing road noise abatement in existing...

  10. Arctic Sea Ice Trafficability - New Strategies for a Changing Icescape

    Dammann, Dyre Oliver

    Sea ice is an important part of the Arctic social-environmental system, in part because it provides a platform for human transportation and for marine flora and fauna that use the ice as a habitat. Sea ice loss projected for coming decades is expected to change ice conditions throughout the Arctic, but little is known about the nature and extent of anticipated changes and in particular potential implications for over-ice travel and ice use as a platform. This question has been addressed here through an extensive effort to link sea ice use and key geophysical properties of sea ice, drawing upon extensive field surveys around on-ice operations and local and Indigenous knowledge for the widely different ice uses and ice regimes of Utqiagvik, Kotzebue, and Nome, Alaska.. A set of nine parameters that constrain landfast sea ice use has been derived, including spatial extent, stability, and timing and persistence of landfast ice. This work lays the foundation for a framework to assess and monitor key ice-parameters relevant in the context of ice-use feasibility, safety, and efficiency, drawing on different remote-sensing techniques. The framework outlines the steps necessary to further evaluate relevant parameters in the context of user objectives and key stakeholder needs for a given ice regime and ice use scenario. I have utilized this framework in case studies for three different ice regimes, where I find uses to be constrained by ice thickness, roughness, and fracture potential and develop assessment strategies with accuracy at the relevant spatial scales. In response to the widely reported importance of high-confidence ice thickness measurements, I have developed a new strategy to estimate appropriate thickness compensation factors. Compensation factors have the potential to reduce risk of misrepresenting areas of thin ice when using point-based in-situ assessment methods along a particular route. This approach was tested on an ice road near Kotzebue, Alaska, where

    2013-01-01

    This study assesses the prospects for presently available abatement technologies to achieve significant reductions in CO 2 emissions from large stationary sources of CO 2 in the EU up to year 2050. The study covers power generation, petroleum refining, iron and steel, and cement production. By simulating capital stock turnover, scenarios that assume future developments in the technology stock, energy intensities, fuel and production mixes, and the resulting CO 2 emissions were generated for each sector. The results confirm that the EU goal for reductions in Greenhouse Gas Emission in the sectors covered by the EU Emission Trading System, i.e., 21% reduction by 2020 as compared to the levels in 2005, is attainable with the abatement measures that are already available. However, despite the optimism regarding the potential for, and implementation of, available abatement strategies within current production processes, our results indicate that the power and industrial sectors will fail to comply with more stringent reduction targets in both the medium term (2030) and long term (2050). Deliberate exclusion from the analysis of mitigation technologies that are still in the early phases of development (e.g., CO 2 capture and storage) provides an indirect measure of the requirements for novel low-carbon technologies and production processes. - Highlights: • Explore the limits for CO 2 emission abatement within current production processes. • Analysis of scenarios for CO 2 emissions from EU power and industrial sectors 2010–2050. • Short-term (2020) emission targets are attainable with available abatement measures. • Fail to comply with more stringent reduction targets in the long term (2050). • Efforts to develop new low-carbon production processes need to be accelerated

  12. Pricing emission permits in the absence of abatement

    Hintermann, Beat

    2012-01-01

    If emissions are stochastic and firms are unable to control them through abatement, the cap in a permit market may be exceeded, or not be reached. I derive a binary options pricing formula that expresses the permit price as a function of the penalty for noncompliance and the probability of an exceeded cap under the assumption of no abatement. I apply my model to the EU ETS, where the rapid introduction of the market made it difficult for firms to adjust their production technology in time for the first phase. The model fits the data well, implying that the permit price may have been driven by firms hedging against stochastic emissions.

  13. Change Strategies and Associated Implementation Challenges: An Analysis of Online Counselling Sessions.

    Rodda, Simone N; Hing, Nerilee; Hodgins, David C; Cheetham, Alison; Dickins, Marissa; Lubman, Dan I

    2017-09-01

    Self-change is the most frequent way people limit or reduce gambling involvement and often the first choice of people experiencing gambling-related problems. Less well known is the range of change strategies gamblers use and how these are selected, initiated or maintained. This study examined change strategies discussed in counselling transcripts from 149 clients who accessed a national online gambling help service in Australia. Using thematic analysis, we identified the presence of six change strategies; cash control and financial management, social support, avoiding or limiting gambling, alternative activities, changing thoughts and beliefs, and self-assessment and monitoring. Four implementation issues were also identified; a mismatch between need and strategy selection or maintenance; importance and readiness versus the cost of implementation; poor or unplanned transitions between strategies; and failure to review the helpfulness of strategies resulting in premature abandonment or unhelpful prolonged application. This study is the first to identify change strategies discussed in online counselling sessions. This study suggests change strategies are frequently discussed in online counselling sessions and we identified multiple new actions associated with change strategies that had not previously been identified. However, multiple implementation issues were identified and further work is required to determine the helpfulness of change strategies in terms of their selection, initiation and maintenance.

  14. Achieving CO2 reductions in Colombia: Effects of carbon taxes and abatement targets

    Calderón, Silvia; Alvarez, Andrés Camilo; Loboguerrero, Ana María; Arango, Santiago; Calvin, Katherine; Kober, Tom; Daenzer, Kathryn; Fisher-Vanden, Karen

    2016-01-01

    In this paper we investigate CO 2 emission scenarios for Colombia and the effects of implementing carbon taxes and abatement targets on the energy system. By comparing baseline and policy scenario results from two integrated assessment partial equilibrium models TIAM-ECN and GCAM and two general equilibrium models Phoenix and MEG4C, we provide an indication of future developments and dynamics in the Colombian energy system. Currently, the carbon intensity of the energy system in Colombia is low compared to other countries in Latin America. However, this trend may change given the projected rapid growth of the economy and the potential increase in the use of carbon-based technologies. Climate policy in Colombia is under development and has yet to consider economic instruments such as taxes and abatement targets. This paper shows how taxes or abatement targets can achieve significant CO 2 reductions in Colombia. Though abatement may be achieved through different pathways, taxes and targets promote the entry of cleaner energy sources into the market and reduce final energy demand through energy efficiency improvements and other demand-side responses. The electric power sector plays an important role in achieving CO 2 emission reductions in Colombia, through the increase of hydropower, the introduction of wind technologies, and the deployment of biomass, coal and natural gas with CO 2 capture and storage (CCS). Uncertainty over the prevailing mitigation pathway reinforces the importance of climate policy to guide sectors toward low-carbon technologies. This paper also assesses the economy-wide implications of mitigation policies such as potential losses in GDP and consumption. An assessment of the legal, institutional, social and environmental barriers to economy-wide mitigation policies is critical yet beyond the scope of this paper. - Highlights: • Four energy and economy-wide models under carbon mitigation scenarios are compared. • Baseline results show that CO

  16. Energy-saving and emission-abatement potential of Chinese coal-fired power enterprise: A non-parametric analysis

    Wei, Chu; Löschel, Andreas; Liu, Bing

    2015-01-01

    In the context of soaring demand for electricity, mitigating and controlling greenhouse gas emissions is a great challenge for China's power sector. Increasing attention has been placed on the evaluation of energy efficiency and CO 2 abatement potential in the power sector. However, studies at the micro-level are relatively rare due to serious data limitations. This study uses the 2004 and 2008 Census data of Zhejiang province to construct a non-parametric frontier in order to assess the abatement space of energy and associated CO 2 emission from China's coal-fired power enterprises. A Weighted Russell Directional Distance Function (WRDDF) is applied to construct an energy-saving potential index and a CO 2 emission-abatement potential index. Both indicators depict the inefficiency level in terms of energy utilization and CO 2 emissions of electric power plants. Our results show a substantial variation of energy-saving potential and CO 2 abatement potential among enterprises. We find that large power enterprises are less efficient in 2004, but become more efficient than smaller enterprises in 2008. State-owned enterprises (SOE) are not significantly different in 2008 from 2004, but perform better than their non-SOE counterparts in 2008. This change in performance for large enterprises and SOE might be driven by the “top-1000 Enterprise Energy Conservation Action” that was implemented in 2006. - Highlights: • Energy-saving potential and CO 2 abatement-potential for Chinese power enterprise are evaluated. • The potential to curb energy and emission shows great variation and dynamic changes. • Large enterprise is less efficient than small enterprise in 2004, but more efficient in 2008. • The state-owned enterprise performs better than non-state-owned enterprise in 2008

  17. Changing currents: a strategy for understanding and predicting the changing ocean circulation.

    Bryden, Harry L; Robinson, Carol; Griffiths, Gwyn

    2012-12-13

    Within the context of UK marine science, we project a strategy for ocean circulation research over the next 20 years. We recommend a focus on three types of research: (i) sustained observations of the varying and evolving ocean circulation, (ii) careful analysis and interpretation of the observed climate changes for comparison with climate model projections, and (iii) the design and execution of focused field experiments to understand ocean processes that are not resolved in coupled climate models so as to be able to embed these processes realistically in the models. Within UK-sustained observations, we emphasize smart, cost-effective design of the observational network to extract maximum information from limited field resources. We encourage the incorporation of new sensors and new energy sources within the operational environment of UK-sustained observational programmes to bridge the gap that normally separates laboratory prototype from operational instrument. For interpreting the climate-change records obtained through a variety of national and international sustained observational programmes, creative and dedicated UK scientists should lead efforts to extract the meaningful signals and patterns of climate change and to interpret them so as to project future changes. For the process studies, individual scientists will need to work together in team environments to combine observational and process modelling results into effective improvements in the coupled climate models that will lead to more accurate climate predictions.

  18. Evaluation of plume potential and plume abatement of evaporative cooling towers in a subtropical region

    Xu Xinhua; Wang Shengwei; Ma Zhenjun

    2008-01-01

    Hong Kong is a typical subtropical region with frequently high humidity in late spring and summer seasons. Plume from evaporative cooling towers, which service air-conditioning systems of civil buildings, has aroused public concerns since 2000 when the fresh water evaporative cooling towers were allowed to be used for high energy efficiency and environmental issues. This paper presents the evaluation of the plume potential and its effect on the sizing of the plume abatement system in a large commercial office building in Hong Kong for practical application. This evaluation was conducted based on a dynamic simulation platform using the typical meteorological year of Hong Kong since the occurrence of the plume heavily depends on the state conditions of the exhaust air from cooling towers and the ambient air, while the state condition of the exhaust air is determined by the total building cooling load and the control strategies of cooling towers employed mainly for improving energy efficiency. The results show that the control strategies have a significant effect on the plume potential and further affect the system design and sizing of the plume abatement system

  19. A change in strategy: Static emotion recognition in Malaysian Chinese

    Chrystalle B.Y. Tan

    2015-12-01

    Full Text Available Studies have shown that while East Asians focused on the center of the face to recognize identities, participants adapted their strategy by focusing more on the eyes to identify emotions, suggesting that the eyes may contain salient information pertaining to emotional state in Eastern cultures. However, Western Caucasians employ the same strategy by moving between the eyes and mouth to identify both identities and emotions. Malaysian Chinese have been shown to focus on the eyes and nose more than the mouth during face recognition task, which represents an intermediate between Eastern and Western looking strategies. The current study examined whether Malaysian Chinese continue to employ an intermediate strategy or shift towards an Eastern or Western pattern (by fixating more on the eyes or mouth respectively during an emotion recognition task. Participants focused more on the eyes, followed by the nose then mouth. Directing attention towards the eye region resulted in better recognition of certain own- than other-race emotions. Although the fixation patterns appear similar for both tasks, further analyses showed that fixations on the eyes were reduced whereas fixations on the nose and mouth were increased during emotion recognition, indicating that participants adapt looking strategies based on their aims.

  20. System-wide and Superemitter Policy Options for the Abatement of Methane Emissions from the U.S. Natural Gas System

    Mayfield, E. N.; Robinson, A. L.; Cohon, J. L.

    2017-12-01

    This work assesses trade-offs between system-wide and superemitter policy options for reducing methane emissions from compressor stations in the U.S. transmission and storage system. Leveraging recently collected national emissions and activity data sets, we developed a new process-based emissions model implemented in a Monte Carlo simulation framework to estimate emissions for each component and facility in the system. We find that approximately 83% of emissions, given the existing suite of technologies, have the potential to be abated, with only a few emission categories comprising a majority of emissions. We then formulate optimization models to determine optimal abatement strategies. Most emissions across the system (approximately 80%) are efficient to abate, resulting in net benefits ranging from 160M to 1.2B annually across the system. The private cost burden is minimal under standard and tax instruments, and if firms market the abated natural gas, private net benefits may be generated. Superemitter policies, namely, those that target the highest emitting facilities, may reduce the private cost burden and achieve high emission reductions, especially if emissions across facilities are highly skewed. However, detection across all facilities is necessary regardless of the policy option and there are nontrivial net benefits resulting from abatement of relatively low-emitting sources.

  1. Marginal abatement cost curves for NOx that account for ...

    A marginal abatement cost curve (MACC) traces out the relationship between the quantity of pollution abated and the marginal cost of abating each additional unit. In the context of air quality management, MACCs typically are developed by sorting end-of-pipe controls by their respective cost effectiveness. Alternative measures, such as renewable electricity, energy efficiency, and fuel switching (RE/EE/FS), are not considered as it is difficult to quantify their abatement potential. In this paper, we demonstrate the use of an energy system model to develop a MACC for nitrogen oxides (NOx) that incorporates both end-of-pipe controls and these alternative measures. We decompose the MACC by sector, and evaluate the cost-effectiveness of RE/EE/FS relative to end-of-pipe controls. RE/EE/FS are shown to produce considerable emission reductions after end-of-pipe controls have been exhausted. Furthermore, some RE/EE/FS are shown to be cost-competitive with end-of-pipe controls. Demonstrate how the MARKAL energy system model can be used to evaluate the potential role of renewable electricity, energy efficiency and fuel switching (RE/EE/FS) in achieving NOx reductions. For this particular analysis, we show that RE/EE/FSs are able to increase the quantity of NOx reductions available for a particular marginal cost (ranging from $5k per ton to $40k per ton) by approximately 50%.

  3. Efficient air pollution abatement for regions in China

    Hu, J.L. [National Chiao Tung University, Taipei (Taiwan). Inst. for Business & Management

    2006-08-15

    This paper computes the efficient air pollution abatement ratios of 30 regions in China during the period 1996-2002. Three air emissions (SO{sub 2}, soot and dust) are considered. Data envelopment analysis (DEA) with a single output (real GDP) and five inputs (labour, real capital stock, SO{sub 2}, dust and soot emissions) is used to compute the target emissions of each region for each year. The efficient abatement ratios of each region in each year are then obtained by dividing the target emission by the actual emission of an air pollutant. Our major findings are: 1. The eastern area is the most efficient region with respect to SO{sub 2}, soot and dust emissions in every year during the research period. 2. The eastern, central and western areas have the lowest, medium and highest 1996-2002 average target abatement ratios of SO, (22.09%, 42.23% and 57.58%), soot (26.19%, 56.34% and 66.37%) and dust (15.20%, 29.09% and 40.59%), respectively. 3. These results are consistent with the Environmental Kuznets Curve (EKC) theory, whereby a more developed area will use environmental goods more efficiently than a less developed area. 4. Compared to dust emission, the average target abatement ratios for SO{sub 2} and soot emissions (as direct outcomes of burning coal) are relatively much higher for all three areas.

  10. Integrated energy planning: Strategies to mitigate climate change

    Ortiz, Johnny N; Sheffield, John W [University of Missouri-Rolla (United States)

    1997-07-01

    The framework convention on climate change, signed by more than 150 governments worldwide in June 1992, calls on parties to the convention undertaken inventories of national sources and sinks of greenhouse gases and to develop plans for responding to climate change. The energy sector is comprised of the major energy demand sectors (industry, residential and commercial, transport and agriculture), and the energy supply sector, which consists of resource extraction, conversion, and delivery of energy products. Greenhouse Gas (GHG) emissions occur at various points in the sector, from resource extraction to end use application, and accordingly, options for mitigation exist at various points. In most countries, will be a major focus of GHG mitigation analysis. The primary focus of this paper is on the identification of strategies that can mitigate climate changes on the basis of integrated energy planing analysis. The overall approach follows a methodology developed by the U.S. Country Studies Program under the framework of the Convention's commitments. It involves the development of scenarios based on energy uses and evaluation of specific technologies that can satisfy demands for energy services. One can compare technologies based on their relative cost to achieve a unit of GHG reduction and other features of interest. This approach gives equal weight to both energy supply and energy demand options. A variety of screening criteria including indicators of cost-effectiveness as well as non-economic analysis concerns, can be used to identify and assess promising options, which can then be combined to create one or more scenarios. Mitigation scenarios are evaluated against the backdrop of a baseline scenario, which simulates assumed to take place in the absence of mitigation efforts. Mitigation scenarios can be designed to meet specific emission reduction targets or to simulate the effect of specific policy inventions. The paper ends with an application using a

  14. Essays on carbon abatement and electricity markets

    Taber, John Timothy

    In the first chapter of this dissertation, I study the effects of a number of policies which affect the electric grid using the SuperOPF, a full AC optimization/simulation framework with optimal investment developed at Cornell University. A 36-node model of the Northeast Power Coordinating Council is used to test policies that aim to reduce CO2, other emissions, or otherwise impact the operation of the electric grid: a base case, with no new environmental legislation; enactment of the Kerry-Lieberman CO2 allowance proposal in 2012; following Fukishima, a retirement of all US nuclear plants by 2022 with and without Kerry-Lieberman; marginal damages from SO2 and NOX emissions charged to coal, gas and oil-fired generation; plug-in hybrid electric vehicle load filling; wind incentives in place; and two cases which combine these. The cases suggest that alternative policies may have very different outcomes in terms of electricity prices, emissions, and health outcomes. In all cases, however, the optimal strategy for future investment is investment in new natural gas combined cycle plants. Policies can change how much new generation is built, whether other plants are built, or what types of plants are retired. The second chapter of my dissertation utilizes the SuperOPF and the model of the Northeast Power Coordinating Council to analyze the issue of carbon leakage. I analyze the effects of a regionally-limited carbon cap and trade program, the Regional Greenhouse Initiative (RGGI), when additional generating assets in non-affected states are included in the analysis. In the face of different carbon prices on generating assets in covered and non-covered states, generation is expected to shift from states bound by RGGI to states outside of RGGI. This carbon leakage may undermine some or all of the benefits of RGGI while simultaneously increasing prices for customers in the area. Even though carbon prices under RGGI are very low, some leakage is occurring, and this leakage

  15. Is flood defense changing in nature? Shifts in the flood defense strategy in six European countries

    Mathilde Gralepois

    2016-12-01

    Full Text Available In many countries, flood defense has historically formed the core of flood risk management but this strategy is now evolving with the changing approach to risk management. This paper focuses on the neglected analysis of institutional changes within the flood defense strategies formulated and implemented in six European countries (Belgium, England, France, the Netherlands, Poland, and Sweden. The evolutions within the defense strategy over the last 30 years have been analyzed with the help of three mainstream institutional theories: a policy dynamics-oriented framework, a structure-oriented institutional theory on path dependency, and a policy actors-oriented analysis called the advocacy coalitions framework. We characterize the stability and evolution of the trends that affect the defense strategy in the six countries through four dimensions of a policy arrangement approach: actors, rules, resources, and discourses. We ask whether the strategy itself is changing radically, i.e., toward a discontinuous situation, and whether the processes of change are more incremental or radical. Our findings indicate that in the European countries studied, the position of defense strategy is continuous, as the classical role of flood defense remains dominant. With changing approaches to risk, integrated risk management, climate change, urban growth, participation in governance, and socioeconomic challenges, the flood defense strategy is increasingly under pressure to change. However, these changes can be defined as part of an adaptation of the defense strategy rather than as a real change in the nature of flood risk management.

  16. Feasibility study on improving SO/sub 2/ abatement economics through improvements in byproduct utilization. Final report. 2 Volumes

    1984-01-17

    This study was undertaken to assess the technical feasibility of improving SO/sub 2/ abatement economics through improvements in byproduct utilization, and to recommend the most appropriate strategy for fostering the development and commericalization of such technology. Existing byproduct technology was reviewed and the potential for new technology assessed. This was done by a literature review and a survey of individuals and organizations actively engaged in this area. The assessment is confined to technical aspects only. This phase of the study concludes that there is a wide range of abatement byproduct technology, at various stages of development, which if appropriately exploited, offers the potential of improving byproduct utility and value, and hence the economics of Canadian SO/sub 2/ abatement. The second phase of this study addresses the problem of the most effective strategy for ensuring the development and commercialization of appropriate byproduct technology. This is based on discussions with individuals and organizations involved in the field, and assessment of the motivation and potential effectiveness of alternative approaches within the context of a diverse Canadian industry, the technology status in Canada and the national need. Includes 51-page bibliography. 400 refs., 14 tabs.

  6. FUEL/CARBON PRICE VS. ABATEMENT TECHNOLOGY IN FREIGHT TRANSPORT

    Eugen Ferdinand Spangenberg

    2017-12-01

    Full Text Available The current situation is the exponential increase in greenhouse gases (GHG, which is mainly caused by industrial and transport activities. The recent Paris agreement in 2015 (Framework Convention on Climate Change COP21, UNFCCC made it clear to everyone that CO2 emissions are to be limited in all areas of life. Alternative fuels with a lower environmental impact than carbon (CO2 emissions are hard to find if the overall footprint is to be taken into account. Nevertheless, there are some fuels that have less impact on climate change. One the other hand, the production of biofuels is a controversial matter, although it is a viable alternative to emissions reduction. CNG or LNG-powered vehicles are also better in terms of environmental pollution, but are hardly better with regard to CO2 impact when a Life Cycle Assessment (LCA is carried out. LNG (liquid natural gas, for example, is the future fuel in the maritime sector because of the stricter environmental regulations (SOx,NOx in the shipping industry. The battery-powered vehicle is another example of an environmentally friendly solution. The afore-mentioned measures can be considered as “abatement“ necessary in order to limit CO2 impact. The study shows that there are significant differences in the environmental impact between transport systems and the corresponding drive-system or associated energy base. The polluter should pay, which is a common basic principle in economic research. The Emission Trading Scheme (ETS has been introduced in order to ensure a reduction in CO2 output – emissions come with a price tag. An overall view is necessary, both en-vironmental and economic impact must be reconciled (cf. Spangenberg - TQI. The future viability of the transport system as we know it may change significantly over time if new environmental requirements or e.g. CO2 taxes or ETS are introduced in the freight sector. The abatement of CO2 should be effected primarily through technological

A comparative biology approach revealed underlying mechanisms of vertebrate seasonal reproduction. Here we review the current understanding of vertebrate seasonal reproduction. We Aso describe the involvement of tissue-specific post-translational modification in functional diversification of a hormone.

  12. Universal precautions: employee resistance and strategies for planned organizational change.

    Kearns, K P; Hogg, M

    1988-01-01

    Health care organizations have been strongly encouraged to design and implement procedures to prevent the spread of HIV/AIDS in the workplace. The procedures will have a dramatic impact on the work habits of health care workers and may even challenge some dominant health care values. Therefore, precautionary procedures are likely to meet with mixed reactions and, perhaps, outright resistance from health care workers. This article identifies some plausible causes for employee resistance to precautionary procedures. After describing the dilemma in terms of competing values and conflicting objectives, some practical managerial strategies for reconciling differences and securing broad-based commitment to preventive policies and procedures are proposed.

  13. Potential Cost-Effective Opportunities for Methane Emission Abatement

    The energy sector was responsible for approximately 84% of carbon dioxide equivalent (CO2e) greenhouse gas (GHG) emissions in the U.S. in 2012 (EPA 2014a). Methane is the second most important GHG, contributing 9% of total U.S. CO2e emissions. A large portion of those methane emissions result from energy production and use; the natural gas, coal, and oil industries produce approximately 39% of anthropogenic methane emissions in the U.S. As a result, fossil-fuel systems have been consistently identified as high priority sectors to contribute to U.S. GHG reduction goals (White House 2015). Only two studies have recently attempted to quantify the abatement potential and cost associated with the breadth of opportunities to reduce GHG emissions within natural gas, oil, and coal supply chains in the United States, namely the U.S. Environmental Protection Agency (EPA) (2013a) and ICF (2014). EPA, in its 2013 analysis, estimated the marginal cost of abatement for non-CO2 GHG emissions from the natural gas, oil, and coal supply chains for multiple regions globally, including the United States. Building on this work, ICF International (ICF) (2014) provided an update and re-analysis of the potential opportunities in U.S. natural gas and oil systems. In this report we synthesize these previously published estimates as well as incorporate additional data provided by ICF to provide a comprehensive national analysis of methane abatement opportunities and their associated costs across the natural gas, oil, and coal supply chains. Results are presented as a suite of marginal abatement cost curves (MACCs), which depict the total potential and cost of reducing emissions through different abatement measures. We report results by sector (natural gas, oil, and coal) and by supply chain segment - production, gathering and boosting, processing, transmission and storage, or distribution - to facilitate identification of which sectors and supply chain

  14. Particulate emission abatement for Krakow boiler houses

    Wysk, R.

    1995-12-31

    Among the many strategies for improving air quality in Krakow, one possible method is to adapt new and improved emission control technology. This project focuses on such a strategy. In order to reduce dust emissions from coal-fueled boilers, a new device called a Core Separator has been introduced in several boiler house applications. This advanced technology has been successfully demonstrated in Poland and several commercial units are now in operation. Particulate emissions from the Core Separator are typically 3 to 5 times lower than those from the best cyclone collectors. It can easily meet the new standard for dust emissions which will be in effect in Poland after 1997. The Core Separator is a completely inertial collector and is based on a unique recirculation method. It can effectively remove dust particles below 10 microns in diameter, the so-called PM-10 emissions. Its performance approaches that of fabric filters, but without the attendant cost and maintenance. It is well-suited to the industrial size boilers located in Krakow. Core Separators are now being marketed and sold by EcoInstal, one of the leading environmental firms in Poland, through a cooperative agreement with LSR Technologies.

  15. Urban Planning and Climate Change: Adaptation and Mitigation Strategies

    Fulvia Pinto

    2014-05-01

    Full Text Available Climate change is a current phenomenon: the temperatures rise, rainfall patterns are changing, glaciers melt and the average global sea level is rising. It is expected that these changes will continue and that the extreme weather events, such as floods and droughts, will become more frequent and intense. The impact and vulnerability factors for nature, for the economy and for our health are different, depending on the territorial, social and economic aspects. The current scientific debate is focused on the need to formulate effective policies for adaptation and mitigation to climate change. The city plays an important role in this issue: it emits the most greenhouse gas emissions (more than 60% of the world population currently lives in urban areas and the city is more exposed and vulnerable to the impacts of climate change. Urban planning and territorial governance play a crucial role in this context: the international debate on the sustainability of urban areas is increasing. It’s necessary to adapt the tools of building regulations to increase the quality of energy - environment of the cities.

  2. Direct crowding out, optimal taxation and pollution abatement

    Van der Ploeg, Frederick [FEE, University of Amsterdam, Amsterdam (Netherlands); Bovenberg, A. Lans [CentER, Tilburg University, Tilburg (Netherlands)

    1993-05-01

    The interactions between direct crowding out, the provision of public goods, optimal taxation and environmental policy are explored. Greener preferences induce a larger tax rate by raising the non-distortionary level of the tax rate. If the marginal productivity of public abatement diminishes rapidly environmental quality improves mainly through a fall in economic activity and emissions. In this case, public consumption increases which crowds out labour supply and private consumption. However, if environmental policy is very effective public consumption falls in order to make room for public abatement. In this case, if labour supply is inelastic with respect to the after-tax wage and direct crowding in is strong, labour supply and economic activity may expand. 1 fig., 7 refs.

    Schroten, A.; Warringa, G.; Bles, M.

    2012-09-15

    Cost curves were calculated for CO2 abatement technologies for Heavy Duty Vehicles. These curves were elaborated for eight different vehicle categories (six categories of truck and two subcategories), as well as for an 'average' truck and bus. Given that cost curves depend very much on underlying assumptions, the MACH model (Marginal Abatement Costs of Heavy duty vehicles) was developed. This model allows users to enter their own assumptions with respect to parameters like fuel prices and cost and lifetime of individual technologies, with the model then generating new cost curves for the various vehicle categories. This background report contains a description of the model and a summary of the results of several model runs.

  4. Forest fires are changing: let’s change the fire management strategy

    Bovio G

    2017-08-01

    Full Text Available Forest fires in Italy are changing. More frequent heatwaves and drought increase the flammability of the vegetation; the abandonment of rural land produces 30.000 ha of newly afforested areas each year; and the wildland-urban interface is expanding with the sprawl of urbanized areas. However, forest fires are rarely understood and managed in their complexity. The public opinion is often misinformed on the causes and consequences of fires in the forest. Moreover, fire management relies almost exclusively on extinction and emergency response, resulting in high costs and limited efficacy versus extreme fire seasons. We advocate to increase the role and investments in wildfire prevention, which can be carried out by fuel-oriented silviculture, such as facilitating less flammable species or prescribed burning, in order to reduce the flammability of the vegetation and mitigate fire intensity in high-leverage areas. A centralized structure is necessary to implement such a strategy and coordinate the competences and actions of all local administrations and actors involved.

  8. Pollution Emissions, Environmental Policy, and Marginal Abatement Costs.

    He, Ling-Yun; Ou, Jia-Jia

    2017-12-05

    Pollution emissions impose serious social negative externalities, especially in terms of public health. To reduce pollution emissions cost-effectively, the marginal abatement costs (MACs) of pollution emissions must be determined. Since the industrial sectors are the essential pillars of China's economic growth, as well as leading energy consumers and sulfur dioxide (SO₂) emitters, estimating MACs of SO₂ emissions at the industrial level can provide valuable information for all abatement efforts. This paper tries to address the critical and essential issue in pollution abatement: How do we determine the MACs of pollution emissions in China? This paper first quantifies the SO₂ emission contribution of different industrial sectors in the Chinese economy by an Input-Output method and then estimates MACs of SO₂ for industrial sectors at the national level, provincial level, and sectoral level by the shadow price theory. Our results show that six sectors (e.g., the Mining and Washing of Coal sector) should be covered in the Chinese pollution emission trading system. We have also found that the lowest SO₂ shadow price is 2000 Yuan/ton at the national level, and that shadow prices should be set differently at the provincial level. Our empirical study has several important policy implications, e.g., the estimated MACs may be used as a pricing benchmark through emission allowance allocation. In this paper, the MACs of industrial sectors are calculated from the national, provincial and sectoral levels; therefore, we provide an efficient framework to track the complex relationship between sectors and provinces.

  9. Relative Greenhouse Gas Abatement Cost Competitiveness of Biofuels in Germany

    Markus Millinger

    2018-03-01

    Full Text Available Transport biofuels derived from biogenic material are used for substituting fossil fuels, thereby abating greenhouse gas (GHG emissions. Numerous competing conversion options exist to produce biofuels, with differing GHG emissions and costs. In this paper, the analysis and modeling of the long-term development of GHG abatement and relative GHG abatement cost competitiveness between crop-based biofuels in Germany are carried out. Presently dominant conventional biofuels and advanced liquid biofuels were found not to be competitive compared to the substantially higher yielding options available: sugar beet-based ethanol for the short- to medium-term least-cost option and substitute natural gas (SNG for the medium to long term. The competitiveness of SNG was found to depend highly on the emissions development of the power mix. Silage maize-based biomethane was found competitive on a land area basis, but not on an energetic basis. Due to land limitations, as well as cost and GHG uncertainty, a stronger focus on the land use of crop-based biofuels should be laid out in policy.

    For a long time, treatment of peritoneal metastases (PM) was mostly palliative and thus, this status was link with “terminal status/despair”. The current multimodal treatment strategy, consisting of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), has been strenuously achieved over time, but seems to be the best treatment option for PM patients. As we reviewed the literature data, we could emphasize some milestones and also, controversies in the history of proposed multimodal treatment and thus, outline the philosophy of this approach, which seems to be an unusual one indeed. Initially marked by nihilism and fear, but benefiting from a remarkable joint effort of human and material resources (multi-center and -institutional research), over a period of 30 years, CRS and HIPEC found their place in the treatment of PM. The next 4 years were dedicated to the refinement of the multimodal treatment, by launching research pathways. In selected patients, with requires training, it demonstrated a significant survival results (similar to the Hepatic Metastases treatment), with acceptable risks and costs. The main debates regarding CRS and HIPEC treatment were based on the oncologists’ perspective and the small number of randomized clinical trials. It is important to statement the PM patient has the right to be informed of the existence of CRS and HIPEC, as a real treatment resource, the decision being made by multidisciplinary teams.

  11. Flexibility to contingency changes distinguishes habitual and goal-directed strategies in humans.

    Lee, Julie J; Keramati, Mehdi

    2017-09-01

    Decision-making in the real world presents the challenge of requiring flexible yet prompt behavior, a balance that has been characterized in terms of a trade-off between a slower, prospective goal-directed model-based (MB) strategy and a fast, retrospective habitual model-free (MF) strategy. Theory predicts that flexibility to changes in both reward values and transition contingencies can determine the relative influence of the two systems in reinforcement learning, but few studies have manipulated the latter. Therefore, we developed a novel two-level contingency change task in which transition contingencies between states change every few trials; MB and MF control predict different responses following these contingency changes, allowing their relative influence to be inferred. Additionally, we manipulated the rate of contingency changes in order to determine whether contingency change volatility would play a role in shifting subjects between a MB and MF strategy. We found that human subjects employed a hybrid MB/MF strategy on the task, corroborating the parallel contribution of MB and MF systems in reinforcement learning. Further, subjects did not remain at one level of MB/MF behaviour but rather displayed a shift towards more MB behavior over the first two blocks that was not attributable to the rate of contingency changes but rather to the extent of training. We demonstrate that flexibility to contingency changes can distinguish MB and MF strategies, with human subjects utilizing a hybrid strategy that shifts towards more MB behavior over blocks, consequently corresponding to a higher payoff.

    Climate change resulted in changes in crop growth duration and planting structure, northward movement of planting region, and more severe plant diseases and insect pests in Northwest China. It caused earlier seeding for spring crop, later seeding for autumn crop, accelerated crop growth, and reduced mortality for winter crop. To adapt to climate change, measures such as optimization of agricultural arrangement, adjustment of planting structure, expansion of thermophilic crops, and development of water-saving agriculture have been taken. Damaging consequences of imbalance between grassland and livestock were enhanced. The deterioration trend of grassland was intensified; both grass quantity and quality declined. With overgrazing, proportions of inferior grass, weeds and poisonous weeds increased in plateau pastoral areas. Returning farmland to grazing, returning grazing to grassland, fence enclosure and artificial grassland construction have been implemented to restore the grassland vegetation, to increase the grassland coverage, to reasonably control the livestock carrying capacity, to prevent overgrazing, to keep balance between grassland and livestock, and to develop the ecological animal husbandry. In Northwest China, because the amount of regional water resources had an overall decreasing trend, there was a continuous expansion in the regional land desertification, and soil erosion was very serious. A series of measures, such as development of artificial precipitation (snow), water resources control, regional water diversion, water storage project and so on, were used effectively to respond to water deficit. It had played a certain role in controlling soil erosion by natural forest protection and returning farmland to forest and grassland. In the early 21st century, noticeable achievements had been made in prevention and control of desertification in Northwest China. The regional ecological environment has been improved obviously, and the desertification trend

  13. One Strategy for Reducing Uncertainty in Climate Change Communications

    Romm, J.

    2011-12-01

    Future impacts of climate change are invariably presented with a very wide range of impacts reflecting two different sets of uncertainties. The first concerns our uncertainty about precisely how much greenhouse gas emissions humanity will emit into the atmosphere. The second concerns our uncertainty about precisely what impact those emissions will have on the climate. By failing to distinguish between these two types of uncertainties, climate scientists have not clearly explained to the public and policymakers what the scientific literature suggests is likely to happen if we don't substantially alter our current emissions path. Indeed, much of climate communications has been built around describing the range of impacts from emissions paths that are increasingly implausible given political and technological constraints, such as a stabilization at 450 or 550 parts per million atmospheric of carbon dioxide. For the past decade, human emissions of greenhouse gases have trended near the worst-case scenarios of the Intergovernmental Panel on Climate Change, emissions paths that reach 800 ppm or even 1000 ppm. The current policies of the two biggest emitters, the United States and China, coupled with the ongoing failure of international negotiations to come to an agreement on restricting emissions, suggests that recent trends will continue for the foreseeable future. This in turn suggests that greater clarity in climate change communications could be achieved by more clearly explaining to the public what the scientific literature suggests the range of impacts are for our current high emissions path. This also suggests that more focus should be given in the scientific literature to better constraining the range of impacts from the high emissions scenarios.

  17. Ecological Footprint in relation to Climate Change Strategy in Cities

    Belčáková, Ingrid; Diviaková, Andrea; Belaňová, Eliška

    2017-10-01

    Ecological footprint determines how much natural resources are consumed by an individual, city, region, state or all inhabitants of our planet in order to ensure their requirements and needs. It includes all activities, from food consumption, housing, transport to waste produced and allows us to compare particular activities and their impacts on the environment and natural resources. Ecological footprint is important issue for making sustainable development concept more popular using simplifications, which provide the public with basic information on situation on our planet. Today we know calculations of global (worldwide), national and local ecological footprints. During our research in cities, we were concentrated on calculation of city’s ecological footprint. The article tries to outline theoretical and assumptions and practical results of climate change consequences in cities of Bratislava and Nitra (Slovakia), to describe potential of mitigating adverse impacts of climate change and to provide information for general and professional public on theoretical assumptions in calculating ecological footprint. The intention is to present innovation of ecological footprint calculation, taking into consideration ecological stability of a city (with a specific focus on micro-climate functions of green areas). Present possibilities to reduce ecological footprint are presented.

  18. Exploring the 'permanent forest' paradigm: might renewable commercial forest estates lead to greater net greenhouse abatement over the longer term?

    Anderson, Graeme

    2007-01-01

    Full text: Understanding permanence: A common perception exists which suggests that long term or 'permanent' tree plantings are considered a superior form of (post 1990) carbon sink, and commercial plantations (which allow for harvesting and replanting) are less useful for abatement. However, common to all forms of forest carbon sink is the issue of permanence. None of these are truly permanent stores of carbon because at any point either a fire, disease, harvest or major event can mean part of the carbon store is released. Why then the perceived bias against sink projects which allow for commercial harvesting and replanting? Let's not forget - things are getting hotter: Australian projections for climate change provide plenty of challenges for current and future forest managers. Over the next century many key forest species may have to endure conditions outside their'current growing range. This poses risks for the emergent offsets industry which needs to be actively managed. Simply planting local indigenous species alone may no longer be the only best practice. Think 'true fate of carbon': It is important that our thinking is not constrained by current rules, as these will continually be refined as our knowledge about carbon systems improves over the next century (between now and 2100 there will be 22 post-Kyoto negotiation periods). Our key focus should be in considering the 'true fate' of carbon, and the real contribution to greenhouse abatement. Policy makers need to keep this in mind, and ensure that the entire carbon life cycle is considered in their decision making. 'Standing forest' versus 'Net abatement effect': There are two effective means for forests to achieve genuine greenhouse abatement. One is the carbon sequestered and stored in the 'standing forest', the other is the greenhouse benefit (carbon flow or net abatement effect) of an ongoing and renewable supply of tree based products from the site (wood, fibre, biomass, biofuel), which replace

  19. Hydropower, an integral part of Canada's climate change strategy

    Fortin, P.

    1999-01-01

    The development and implementation of a climate change policy could be among the most far-reaching environmental initiatives ever embarked upon in Canada and abroad. If Canada is to stabilize or reduce its Greenhouse Gas (GHG) emissions over the long term, a significant adjustment to Canadian industry will be required as we move away from fossil fuel-intensive and GHG producing activities. Future hydroelectric projects provide Canada with a unique opportunity to significantly reduce the costs associated with stabilizing its GHG emissions. In addition, the energy storage and dispatchability associated with hydropower can support development of other low emitting renewable resources such as wind and solar. This document discusses the potential role of hydropower as a tool to reduce emissions, recommends action to reduce barriers facing hydropower and comments on some of the policy tools available to manage Canada's GHG emissions.

  6. Diagnostic imaging in oncology: New challenges and changing strategies

    Castellino, Ronald A.; Schwartz, Lawrence H.

    1997-01-01

    Diagnostic radiology and nuclear medicine studies, both imaging and therapeutic, play important roles in screening, staging, monitoring of treatment, and in long term surveillance of oncologic patients. Frequently, information from these studies, as well as from ancillary data (such as the clinical examination and laboratory studies) overlap, and it is sometimes unclear which tests and examinations to perform. Current changes in the delivery and funding of health care are prompting all specialties to evaluate their patterns of care. Some of the important questions to be addressed in medical imaging include: Which studies are pertinent at initial staging, e.g., those that impact patient management, serve as important baselines for comparison with subsequent studies, etc? How sensitive and specific are these studies, e.g., when can they obviate the need for more invasive confirmatory exams? What are the critical questions in monitoring response to therapy, e.g., the significance of the 'post treatment residual mass' and ways to elucidate its etiology? Which tests should be performed in surveillance for disease relapse, and how frequently should they be done? Purpose/Objective: To develop a set of guidelines for developing rational approaches for utilizing diagnostic imaging studies

    Research indicates that the public views zoos and aquariums as reliable and trusted sources for information on conservation. Additionally, visiting zoos and aquariums helps people reconsider their connections to conservation issues and solutions. The Aquarium of the Pacific, an AZA-accredited institution that serves the most ethnically diverse population of all aquariums in the nation, is using exhibit space, technology, public programming, and staff professional development to present a model for how aquariums can promote climate literacy. Our newest galleries and programs are designed to immerse our visitors in experiences that connect our live animal collection to larger themes on ocean change. The Aquarium is supporting our new programming with a multifaceted staff professional development that exposes our interpretive staff to current climate science and researchers as well as current social science on public perception of climate science. Our staff also leads workshops for scientists; these sessions allow us to examine learning theory and develop tools to communicate science and controversial subjects effectively. Through our partnerships in the science, social science, and informal science education communities, we are working to innovate and develop best practices in climate communication.

Some of the important questions to be addressed in medical imaging include: Which studies are pertinent at initial staging, e.g., those that impact patient management, serve as important baselines for comparison with subsequent studies, etc? How sensitive and specific are these studies, e.g., when can they obviate the need for more invasive confirmatory exams? What are the critical questions in monitoring response to therapy, e.g., the significance of the 'post treatment residual mass' and ways to elucidate its etiology? Which tests should be performed in surveillance for disease relapse, and how frequently should they be done?

  9. Concepts and measures for greenhouse gas abatement

    Lamprecht, F.

    1995-01-01

    On April 3 this year, the Hannover Fair will open, and at the same time in Berlin, the participants of the UN conference of the signatory states to the Climate Change Convention will enter the decisive phase of debates about concrete proposals and standards for giving life to the Convention and provide for practical application. Although the conference is not expected to achieve contractual commitments for reducing the CO 2 emissions, it has indeed prepared the ground for enhanced willingness to combat emissions, which is shown in initiatives such as the public commitment of German industry, to cut back CO 2 emissions by 20% until the year 2005, (1987 being taken as the reference year). Industry announced to achieve this goal by appropriate technology for enhancing the efficiency of power generating systems and energy utilization. The Hannover Fair is the right place to look for the required technology and equipment, and public utilities will even be offered comprehensive problem solutions for their supply services.

  11. Greenhouse gas abatement cost curves of the residential heating market. A microeconomic approach

    Dieckhoener, Caroline; Hecking, Harald

    2012-01-01

    In this paper, we develop a microeconomic approach to deduce greenhouse gas abatement cost curves of the residential heating sector. By accounting for household behavior, we find that welfare-based abatement costs are generally higher than pure technical equipment costs. Our results are based on a microsimulation of private households' investment decision for heating systems until 2030. The households' investment behavior in the simulation is derived from a discrete choice estimation which allows investigating the welfare costs of different abatement policies in terms of the compensating variation and the excess burden. We simulate greenhouse gas abatements and welfare costs of carbon taxes and subsidies on heating system investments until 2030 to deduce abatement curves. Given utility maximizing households, our results suggest a carbon tax to be the welfare efficient policy. Assuming behavioral misperceptions instead, a subsidy on investments might have lower marginal greenhouse gas abatement costs than a carbon tax.

    2011-01-01

    This U.S. Geological Survey (USGS) Global Change Science Strategy expands on the Climate Variability and Change science component of the USGS 2007 Science Strategy, “Facing Tomorrow’s Challenges: USGS Science in the Coming Decade” (U.S. Geological Survey, 2007). Here we embrace the broad definition of global change provided in the U.S. Global Change Research Act of 1990 (Public Law 101–606,104 Stat. 3096–3104)—“Changes in the global environment (including alterations in climate, land productivity, oceans or other water resources, atmospheric chemistry, and ecological systems) that may alter the capacity of the Earth to sustain life”—with a focus on climate and land-use change.There are three major characteristics of this science strategy. First, it addresses the science required to broadly inform global change policy, while emphasizing the needs of natural-resource managers and reflecting the role of the USGS as the science provider for the Department of the Interior and other resource-management agencies. Second, the strategy identifies core competencies, noting 10 critical capabilities and strengths the USGS uses to overcome key problem areas. We highlight those areas in which the USGS is a science leader, recognizing the strong partnerships and effective collaboration that are essential to address complex global environmental challenges. Third, it uses a query-based approach listing key research questions that need to be addressed to create an agenda for hypothesis-driven global change science organized under six strategic goals. Overall, the strategy starts from where we are, provides a vision for where we want to go, and then describes high-priority strategic actions, including outcomes, products, and partnerships that can get us there. Global change science is a well-defined research field with strong linkages to the ecosystems, water, energy and minerals, natural hazards, and environmental health components of the USGS Science Strategy

  15. Farmers’ Adaptation Strategies to Climate Change and Their Implications in the Zou Department of South Benin

    Adégnandjou Mahouna Roland Fadina

    2018-01-01

    Full Text Available Climate change is a global phenomenon. Its impact on agricultural activities in developing countries has increased dramatically. Understanding how farmers perceive climate change and how they adapt to it is very important to the implementation of adequate policies for agricultural and food security. This paper aims to contribute to an understanding of farmers’ adaptation choices, determinants of the adaptation choices and the long-term implications of the adaptation choices. Data were collected from 120 respondents in the Zou Department of Benin. A binary logit model was used to analyze the factors influencing household decisions to adapt to climate change. Multinomial logistic regression analysis was estimated to analyze the factors influencing households’ choice of adaptation strategies to climate change. The results show that farmers have a developed perception of climate change. These changes are translated by rainfall disturbances (rainfall delays, early cessation, bad rainfall distribution etc., shortening of the small dry season, increasing of temperature and sometimes, violent winds. The survey reveals that Benin farmers adopt many strategies in response to climate change. These strategies include “Crop–livestock diversification and other good practices (mulching, organic fertilizer,” “Use of improved varieties, chemical fertilizers and pesticides,” “Agroforestry and perennial plantation” and “Diversification of income-generating activities.” The findings also reveal that most of the respondents use these strategies in combination. From the binary logit model, we know that “farming experience” and “educational level of household head” positively influence adaptation decisions. The result of the multinomial logit analysis shows that farming experience, educational level, farm size and gender have a significant impact on climate change adaptation strategies. Based on in-depth analysis of each strategy, we

  16. How does a change in the control room design affect diagnostic strategies in nuclear power plants?

    Kim, Dong Young; Kim, Jonghyun

    2014-01-01

    Recently, main control rooms have been considerably changed by modern computer techniques. Some of the features that distinguish digital control rooms from conventional, analog rooms in nuclear power plants include advanced alarm systems, graphic information display systems, computerized procedure systems, and soft control. These features can bring changes in operator tasks, changing the characteristics of tasks or creating new tasks for operators. It is especially expected that these features may bring out changes in the operator's diagnostic tasks and strategies in a digital control room as compared with an analog control room. This study investigates the differences in the operator's diagnostic tasks and strategies in analog and digital control rooms. This study also attempts to evaluate how new systems in a digital control room affect diagnostic strategies. Three different approaches, which are complementary, are used to identify diagnostic strategies in the digital control room and in the analog control room: (1) observation in the simulator, (2) interview with operators, and (3) a literature review. The results show that the digital control room introduces new diagnosis strategies compared with the analog control room while also changing the characteristics of the strategies, mostly by gaining more support from the computerized system.

    Teixeira Carneiro, J.M.; Moutinho Dos Santos, E.

    1999-01-01

    This article is part of a series of four dedicated to the study of the global oil competition game through the analytical framework proposed by Michael Porter, from the University of Harvard. By means of a questionnaire answered by top executives in ten oil companies, the authors investigate the changes in the competitive strategy of these companies in the downstream side of the oil business due to deregulation and privatization. The paper starts by establishing the relationship between Porter's generic competitive strategies and specific competitive methods. Then, it describes how companies have changes their competitive methods after privatization and major deregulation. Changes in the industry structure are also analyzed. (authors)

  2. Flexibility to contingency changes distinguishes habitual and goal-directed strategies in humans.

    Julie J Lee

    2017-09-01

    Full Text Available Decision-making in the real world presents the challenge of requiring flexible yet prompt behavior, a balance that has been characterized in terms of a trade-off between a slower, prospective goal-directed model-based (MB strategy and a fast, retrospective habitual model-free (MF strategy. Theory predicts that flexibility to changes in both reward values and transition contingencies can determine the relative influence of the two systems in reinforcement learning, but few studies have manipulated the latter. Therefore, we developed a novel two-level contingency change task in which transition contingencies between states change every few trials; MB and MF control predict different responses following these contingency changes, allowing their relative influence to be inferred. Additionally, we manipulated the rate of contingency changes in order to determine whether contingency change volatility would play a role in shifting subjects between a MB and MF strategy. We found that human subjects employed a hybrid MB/MF strategy on the task, corroborating the parallel contribution of MB and MF systems in reinforcement learning. Further, subjects did not remain at one level of MB/MF behaviour but rather displayed a shift towards more MB behavior over the first two blocks that was not attributable to the rate of contingency changes but rather to the extent of training. We demonstrate that flexibility to contingency changes can distinguish MB and MF strategies, with human subjects utilizing a hybrid strategy that shifts towards more MB behavior over blocks, consequently corresponding to a higher payoff.

  3. Subjective well-being in times of social change: congruence of control strategies and perceived control.

    Grümer, Sebastian; Silbereisen, Rainer K; Heckhausen, Jutta

    2013-01-01

    This paper investigates the association between perceptions of broader changes in the social-ecological context and individuals' subjective well-being (SWB). Macro-level societal changes such as globalization or demographic change give rise to new demands for individual functioning at work and/or in the family. Such new demands associated with social change are stressful and likely to be related to lower levels of SWB. Being active agents, individuals attempt to deal with social change and its increasing demands to protect their SWB. The present study investigates which kinds of control strategies are most effective in protecting one's SWB. Specifically, we predicted that control strategies of goal engagement will be most effective under conditions of perceived high control, and control strategies of goal disengagement will be most effective under conditions of perceived low control. In a large sample of 2537 German adults, work- and family-related demands associated with social change were found to be negatively linked to SWB. Moreover and in line with the motivational theory of lifespan development, control strategies of goal engagement and disengagement were beneficial for SWB to the extent that they matched the perceived control of the demands associated with social change.

  4. Climate change perceptions and local adaptation strategies of hazard-prone rural households in Bangladesh

    G.M. Monirul Alam

    2017-01-01

    Full Text Available Adaptation is a key strategy that can alleviate the severity of climate change impacts on agriculture and food production. Adaptation strategies are unlikely to be effective without an understanding of the farmers’ perceptions of climate change. This paper explores the local knowledge of adaptation in response to the perceived impacts of climate change and climatic hazards using a survey of 380 resource-poor riverbank erosion-prone households in Bangladesh. The results indicate that the respondents’ perceptions of changes in the climate and of extreme climatic events are similar to the observed climate data. Households have recognized the impacts on their livelihood and resources, resulting in an increased sense of vulnerability. To build resilience, households have undertaken a range of farming and non-farming adaptation strategies, which vary significantly among the farming groups. The important adaptation strategies include adopting new crop varieties, changing planting time, homestead gardening, planting trees and migration. Improved access to finance and to information about appropriate strategies appears to be crucial to support adaptation processes locally and thus to enhance the resilience of vulnerable households.

  5. Organizational models as configurations of structure, culture, leadership, control, and change strategy

    Janićijević Nebojša

    2017-01-01

    Full Text Available Starting from the axioms of consistency, stability, contingency, and configuration, research on organizational structure, culture, control, leadership, and change management strategy has shown that their typical configurations, or models, can be differentiated according to the same two criteria: distribution of power and dominant organizational dimension. On the one hand there are models of structure, culture, control, leadership, and change management strategy that are based on an unequal, or authoritarian, distribution of power within organizations, while on the other hand there are models that are based on democratic, or equal, distribution of power. Also, on the one hand there are models of structure, culture, control, leadership, and change strategy that are based on work structure and tasks, while on the other hand there are models of these organizational components that are based on social structure, people, and their relationships. Harmonization of typical configurations of organizational structure, culture, control, leadership, and change strategy occurs due to the harmonization of the differentiation criteria. Based on this harmonization, four organizational models have been identified as typical configurations of structure, culture, control, leadership, and change strategy: the autocratic, bureaucratic, innovative, and task models. Each of these models is effective in a different environmental contingency.

  6. Zeolite ZSM5 catalysts for abatement of nitrogen oxide

    Ganemi, Bager

    1999-07-01

    Airborne pollutants from the combustion of fossil fuels are a global problem. Emission of nitrogen oxides (NO{sub x}) is increasing with the worldwide increase in the use of energy. Atmospheric and photochemical reactions link nitrogen oxides to hydrocarbons and tropospheric ozone. The emission of NO{sub x} has to be tackled urgently in order to limit the harmful effects of anthropogenic activity on the environment. The subject of this thesis is catalytic nitrogen oxide abatement through direct decomposition and reduction by methane over ion-exchanged zeolite ZSM5. The work covers catalytic conversion and surface intermediates, including correlations with the level of exchanged Cu{sup 2+} cations and Ni{sup 2+} or Pd{sup 2+} co-cations. Special attention is given to the aluminium content of the support and changes in structural parameters. It was found that NO{sub x} conversion over cation-exchanged ZSM5 is strongly influenced by the ion-exchange procedure and by the above material parameters. Characterization of Cu-ZSM5 reveals that approximately two molecules of water per Cu{sup 2+} ion desorb at temperatures between 150 and 350 Deg C, in addition to the conventional dehydration at lower temperatures. The desorbed water comes from the decomposition of Cu(OH){sub 2}. Decomposition of hydroxylated copper ions results in the formation Of Cu{sup 2+}-O-Cu{sup 2+} dimers, which are suggested to be the active sites for catalytic decomposition of NO. Acid sites are important for the dispersion of copper ions on the catalyst surface. Acid sites are also important for the interaction between copper species and the zeolite. Increased acidity leads to a stronger interaction between the exchanged cation and the framework, i.e. the exchanged cations become more resistant to mobility. The stronger bond between the exchanged cations and lattice oxygen also prevents dealumination of the catalyst and decreases the thermal expansion at higher temperatures. The temperature of

  8. Regional differences in China's CO2 abatement cost

    He, Xiaoping

    2015-01-01

    Under a framework of output distance function with multiple outputs, the study discusses the carbon abatement cost at provincial and regional levels in China, using the shadow price analysis. The findings show that the abatement cost, reflecting the marginal opportunity cost of carbon reduction, varies greatly among the provinces. On average, the abatement cost of the eastern region was much higher than that of the mid-western region during the observed period. The findings provide evidence that the carbon prices in the current ETS pilots have been much lower than desired levels, implying inefficiency of the markets. The wide range of the abatement cost estimates supports that the equi-marginal principle does not hold for the regulations on carbon pollution at regional levels. The regional cost differences indicate the huge potential for China to minimize the total abatement cost with policy instruments that may motive the emissions moving from areas of low abatement cost to where the abatement cost is higher. For a few undeveloped provinces that are environmentally fragile and have high abatement cost, supplementary measures will be needed to reduce the negative impact of carbon cutbacks on the poor to the minimum. - Highlights: • The marginal abatement cost of CO 2 is defined by the shadow price measure. • A linear programming model based on distance function is established. • Marginal abatement costs at provincial level are empirical investigated. • The abatement cost varies across provinces and regions in China. • The findings provide evidence that the current ETS pilots are inefficient

  9. Visualizing Changes in Strategy Use across Attempts via State Diagrams: A Case Study

    Deirdre Kerr

    2016-01-01

    Full Text Available Game log data have great potential to provide actionable information about the in-game behavior of players. However, these low-level behavioral data are notoriously difficult to analyze due to the challenges associated with extracting meaning from sparse data stored at such a small grain size. This paper describes a three-step solution that uses cluster analysis to determine which strategies players use to solve levels in the game, sequence mining to identify changes in strategy across multiple attempts at the same level, and state transition diagrams to visualize the strategy sequences identified by the sequence mining. In the educational video game used in this case study, cluster analysis successfully identified 15 different in-game strategies. The sequence mining found an average of 40 different sequences of strategy use per level, which the state transition diagrams successfully displayed in an interpretable way.

  10. Abatement costs of post-Kyoto climate regimes

    Elzen, Michel den; Lucas, Paul; Vuuren, Detlef van

    2005-01-01

    This article analyses the abatement costs of three post-Kyoto regimes for differentiating commitments compatible with stabilising atmospheric greenhouse gases concentrations at 550 ppmv CO 2 equivalent in 2100. The three regimes explored are: (1) the Multi-Stage approach assumes a gradual increase in the number of Parties involved who are adopting either emission intensity or reductions targets; (2) the Brazilian Proposal approach, i.e. the allocation or reductions based on countries' contribution to temperature increase; (3) Contraction and Convergence, with full participation in convergence of per capita emission allowances. In 2050, the global costs increase up to about 1% of the world GDP, ranging from 0.5% to 1.5%, depending on baseline scenario and marginal abatement costs. Four groups of regions can be identified on the basis of similar costs (expressed as the percentage of GDP). These are: (1) OECD regions with average costs; (2) FSU, the Middle East and Latin America with high costs; (3) South-East Asia and East Asia (incl. China) with low costs; and (4) South Asia (incl. India) and Africa with net gains from emissions trading for most regimes. The Brazilian Proposal approach gives the highest costs for groups 1 and 2. The distribution of costs for the Contraction and Convergence approach highly depends on the convergence year. The Multi-Stage approach and Contraction and Convergence (convergence year 2050) seem to result in relatively the most even distribution of costs amongst all Parties

  11. Tradeable emission permit in Dutch acidification abatement policy

    1996-12-31

    Target groups as well as the government are under the spell of economic instruments as part of environmental policy. Under this heading fall (regulatory) taxes and tradeable emission permits (VER). Of the two, VER, particularly, receive a lot of attention. From the target groups, because the flexibility of VER means working cost-effectively, which could lead to cost savings. From the government, because it can have more faith in the viability of emission ceilings, and has less need to pass detailed legislation. The latter conforms nicely to the philosophy `government at arm`s length`. The Ministry of Environment has had a study made on the feasibility of VER in the context of the acidification abatement policy in the Netherlands. The development and implementation of policy concerning acidification abatement is at an advanced stage, with deposition targets already set for 2000 and 2010 (2400 and 1400 acid equivalents/ha/year, respectively, averaged for afforested areas). From these, also emission reduction targets per target group are deduced, which can be used in a VER system. The main starting point of the study was to gain more insight into the practical aspects of VER. One important question is what form a VER system for the Netherlands should have to take. Also, an investigation was made into the activities which are necessary to introduce a VER system as well as the time, manpower and money these activities entail

    Current decisions on greenhouse gas emissions may have effects on human well being for centuries. This project has aimed to extend the economic models designed for analyzing this particular issue. A closely related topic follows from the fact that emitting CO{sub 2} can be interpreted as a utilization of a free access resource, i.e., when countries gain from utilizing cheap fossil fuels (relative to noncarbon energy sources), the possible loss any country suffers from climate change is only a negligible fraction of the total loss of all countries. Thus, from a global point of view, the incentives for an individual country to abate emissions is low. Economic understanding of these problems calls for dynamic game-theoretical models

  17. Organisational change stressors and nursing job satisfaction: the mediating effect of coping strategies.

    Teo, Stephen T T; Pick, David; Newton, Cameron J; Yeung, Melissa E; Chang, Esther

    2013-09-01

    To examine the mediating effect of coping strategies on the consequences of nursing and non-nursing (administrative) stressors on the job satisfaction of nurses during change management. Organisational change can result in an increase in nursing and non-nursing-related stressors, which can have a negative impact on the job satisfaction of nurses employed in health-care organisations. Matched data were collected in 2009 via an online survey at two time-points (six months apart). Partial least squares path analysis revealed a significant causal relationship between Time 1 administrative and role stressors and an increase in nursing-specific stressors in Time 2. A significant relationship was also identified between job-specific nursing stressors and the adoption of effective coping strategies to deal with increased levels of change-induced stress and strain and the likelihood of reporting higher levels of job satisfaction in Time 2. The effectiveness of coping strategies is critical in helping nurses to deal with the negative consequences of organisational change. This study shows that there is a causal relationship between change, non-nursing stressors and job satisfaction. Senior management should implement strategies aimed at reducing nursing and non-nursing stress during change in order to enhance the job satisfaction of nurses. © 2013 John Wiley & Sons Ltd.

  18. Policy Entrepreneurs and Change Strategies: Lessons from Sixteen Case Studies of Water Transitions around the Globe

    Sander Meijerink

    2010-06-01

    Full Text Available This paper focuses on the role of policy entrepreneurs in realizing water policy transitions. The central questions are to what extent have policy entrepreneurs played a role in realizing major change in water policies, who are these policy entrepreneurs, and what strategies have they used to bring about change? The policy science literature suggests that policy entrepreneurs have an "arsenal" of possible strategies for achieving change. Based on a comparative analysis of water policy changes in 15 countries around the globe and the European Union, we investigate which strategies have in practice been used by policy entrepreneurs, to what effect, and which lessons for managing water transitions we can draw from this. The comparative case analysis shows that individuals play complementary roles; hence, entrepreneurship in water management is often collective entrepreneurship. Strategies of coalition building, the manipulation of decision making forums, and the strategic framing of issues and windows are crucial to understanding water policy change, which suggests that the management of water policy transitions is a highly political game. We conclude by listing recommendations for those who would like to direct water policy change.

  19. A strategy for implementing genomics into nursing practice informed by three behaviour change theories.

    Leach, Verity; Tonkin, Emma; Lancastle, Deborah; Kirk, Maggie

    2016-06-01

    Genomics is an ever increasing aspect of nursing practice, with focus being directed towards improving health. The authors present an implementation strategy for the incorporation of genomics into nursing practice within the UK, based on three behaviour change theories and the identification of individuals who are likely to provide support for change. Individuals identified as Opinion Leaders and Adopters of genomics illustrate how changes in behaviour might occur among the nursing profession. The core philosophy of the strategy is that genomic nurse Adopters and Opinion Leaders who have direct interaction with their peers in practice will be best placed to highlight the importance of genomics within the nursing role. The strategy discussed in this paper provides scope for continued nursing education and development of genomics within nursing practice on a larger scale. The recommendations might be of particular relevance for senior staff and management. © 2016 John Wiley & Sons Australia, Ltd.

  20. Taking a climate chance: a procedural critique of Vietnam's climate change strategy.

    Fortier, François

    2010-01-01

    This article asks through what processes and for which interests the emerging Vietnamese climate change strategy is being designed, and if, ultimately, it is likely or not to be effective in the face of the looming threat. Through a review of an emerging body of literature and field observations, the paper finds the strategy partial and problematic in several ways. Its technocratic process prevents a pluralist representation of interests, obfuscating and perpetuating sectorial ones, at the expense of a more transparent and democratic resource allocation. The strategy therefore reflects and reinforces existing power relations in both politics and production. It feeds into a business-as-usual complacency, protecting national and international interests vested in unchallenged continuity, even when considering post-carbon technological fixes, which largely serve to expand capital accumulation opportunities. The article concludes that the national climate change strategy provides an illusion of intervention and security, but largely fails to identify and mitigate the underlying causes of climate change, or to lay the ground for a robust mid- and long-term adaptation strategy that can cope with yet unknown levels of climatic and other structural changes.

  1. Influence of the management strategy model on estimating water system performance under climate change

    Francois, Baptiste; Hingray, Benoit; Creutin, Jean-Dominique; Hendrickx, Frederic

    2015-04-01

    The performance of water systems used worldwide for the management of water resources is expected to be influenced by future changes in regional climates and water uses. Anticipating possible performance changes of a given system requires a modeling chain simulating its management. Operational management is usually not trivial especially when several conflicting objectives have to be accounted for. Management models are therefore often a crude representation of the real system and they only approximate its performance. Estimated performance changes are expected to depend on the management model used, but this is often not assessed. This communication analyzes the influence of the management strategy representation on the performance of an Alpine reservoir (Serre-Ponçon, South-East of France) for which irrigation supply, hydropower generation and recreational activities are the main objectives. We consider three ways to construct the strategy named as clear-, short- and far-sighted management. They are based on different forecastability degrees of seasonal inflows into the reservoir. The strategies are optimized using a Dynamic Programming algorithm (deterministic for clear-sighted and implicit stochastic for short- and far-sighted). System performance is estimated for an ensemble of future hydro-meteorological projections obtained in the RIWER2030 research project (http://www.lthe.fr/RIWER2030/) from a suite of climate experiments from the EU - ENSEMBLES research project. Our results show that changes in system performance is much more influenced by changes in hydro-meteorological variables than by the choice of strategy modeling. They also show that a simple strategy representation (i.e. clear-sighted management) leads to similar estimates of performance modifications than those obtained with a representation supposedly closer to real world (i.e. the far-sighted management). The Short-Sighted management approach lead to significantly different results, especially

  2. State of the evidence regarding behavior change theories and strategies in nutrition counseling to facilitate health and food behavior change.

    Spahn, Joanne M; Reeves, Rebecca S; Keim, Kathryn S; Laquatra, Ida; Kellogg, Molly; Jortberg, Bonnie; Clark, Nicole A

    2010-06-01

    Behavior change theories and models, validated within the field of dietetics, offer systematic explanations for nutrition-related behavior change. They are integral to the nutrition care process, guiding nutrition assessment, intervention, and outcome evaluation. The American Dietetic Association Evidence Analysis Library Nutrition Counseling Workgroup conducted a systematic review of peer-reviewed literature related to behavior change theories and strategies used in nutrition counseling. Two hundred fourteen articles were reviewed between July 2007 and March 2008, and 87 studies met the inclusion criteria. The workgroup systematically evaluated these articles and formulated conclusion statements and grades based upon the available evidence. Strong evidence exists to support the use of a combination of behavioral theory and cognitive behavioral theory, the foundation for cognitive behavioral therapy (CBT), in facilitating modification of targeted dietary habits, weight, and cardiovascular and diabetes risk factors. Evidence is particularly strong in patients with type 2 diabetes receiving intensive, intermediate-duration (6 to 12 months) CBT, and long-term (>12 months duration) CBT targeting prevention or delay in onset of type 2 diabetes and hypertension. Few studies have assessed the application of the transtheoretical model on nutrition-related behavior change. Little research was available documenting the effectiveness of nutrition counseling utilizing social cognitive theory. Motivational interviewing was shown to be a highly effective counseling strategy, particularly when combined with CBT. Strong evidence substantiates the effectiveness of self-monitoring and meal replacements and/or structured meal plans. Compelling evidence exists to demonstrate that financial reward strategies are not effective. Goal setting, problem solving, and social support are effective strategies, but additional research is needed in more diverse populations. Routine documentation

  5. Marginal Abatement Cost of CO2 in China Based on Directional Distance Function: An Industry Perspective

    Bowen Xiao

    2017-01-01

    Full Text Available Industrial sectors account for around 70% of the total energy-related CO2 emissions in China. It is of great importance to measure the potential for CO2 emissions reduction and calculate the carbon price in industrial sectors covered in the Emissions Trading Scheme and carbon tax. This paper employs the directional distance function to calculate the marginal abatement costs of CO2 emissions during 2005–2011 and makes a comparative analysis between our study and the relevant literature. Our empirical results show that the marginal abatement costs vary greatly from industry to industry: high marginal abatement costs occur in industries with low carbon intensity, and vice versa. In the application of the marginal abatement cost, the abatement distribution scheme with minimum cost is established under different abatement targets. The conclusions of abatement distribution scheme indicate that those heavy industries with low MACs and high carbon intensity should take more responsibility for emissions reduction and vice versa. Finally, the policy implications for marginal abatement cost are provided.

  8. Embracing technology? Using change management strategies to improve the use of continuous lateral rotation therapy.

    Cybulski, Pamela; Zantinge, Johanna; Abbott-McNeil, Deanna

    2006-01-01

    The purpose of this quality improvement initiative was to improve the utilization of continuous lateral rotation therapy (CLRT) in a nine-bed community hospital ICU within the context of a nurse-driven protocol. Nursing focus groups, analyzed using a strength, weakness, opportunity, threat (SWOT) approach, resulted in the implementation of four interventions over seven weeks. Change management strategies guided all aspects of the project. Results showed a modest increase in the utilization of CLRT. This initiative demonstrates that change management strategies may assist with the incorporation of technology into nursing practice by increasing empowerment and creating an attachment to and responsibility for outcomes.

  10. Perception, Mitigation and Adaptation Strategies of Irrigated Paddy Farmer Community to Face Climate Change

    Siska Rasiska Suantapura

    2016-06-01

    Full Text Available Climate change has a real impact on the condition of agriculture in developing countries, including Indonesia. Irrigated paddy farmers are the ones really feeling the impact of climate change. Therefore, we need to understand the perceptions, mitigation and adaptation strategies of irrigated paddy farmer community to face climate change. The study is conducted in Indramayu and Tasikmalaya Regency in West Java by using descriptive survey method, regression analysis and path analysis through Structural Equation Modelling approach with Lisrel TM 8.5. The results showes that: (1 changes to climate variability affects the productivity of rice; (2 perception of irrigated paddy farmer community on climate change and its affects are influenced by internal and external factors; and (3 adaptation strategy are influenced by internal and external factors, whereas no mitigation strategy. Therefore, mitigation and adaptation strategies with site specific location are very necessary improving climate information services, increasing empowerment of farmers through field schools, and providing the provision of facilities that are practical and adaptive to climate.

  13. Emissions leakage and subsidies for pollution abatement. Pay the polluter or the supplier of the remedy?

    Fischer, Carolyn; Greaker, Mads; Rosendahl, Knut Einar

    2012-07-01

    Asymmetric regulation of a global pollutant between countries can alter the competitiveness of industries and lead to emissions leakage. For most types of pollution, abatement technologies are available for firms to produce with lower emissions. However, the suppliers of those technologies tend to be less than perfectly competitive, particularly when both emissions regulations and advanced technologies are new. In this context of twin market failures, we consider the relative effects and desirability of subsidies for abatement technology. We find a more robust recommendation for upstream subsidies than for downstream subsidies. Downstream subsidies tend to increase global abatement technology prices, reduce pollution abatement abroad and increase emission leakage. On the contrary, upstream subsidies reduce abatement technology prices, and hence also emissions leakage.(Author)

  14. Identifying Effective Strategies for Climate Change Education: The Coastal Areas Climate Change Education (CACCE) Partnership Audiences and Activities

    Ryan, J. G.; Feldman, A.; Muller-Karger, F. E.; Gilbes, F.; Stone, D.; Plank, L.; Reynolds, C. J.

    2011-12-01

    Many past educational initiatives focused on global climate change have foundered on public skepticism and disbelief. Some key reasons for these past failures can be drawn directly from recognized best practices in STEM education - specifically, the necessity to help learners connect new knowledge with their own experiences and perspectives, and the need to create linkages with issues or concerns that are both important for and relevant to the audiences to be educated. The Coastal Areas Climate Change Education (CACCE) partnership has sought to follow these tenets as guiding principles in identifying critical audiences and developing new strategies for educating the public living in the low-lying coastal areas of Florida and the Caribbean on the realities, risks, and adaptation and mitigation strategies for dealing with the regional impacts of global climate change. CACCE is currently focused on three key learner audiences: a) The formal education spectrum, targeting K-12 curricula through middle school marine science courses, and student and educator audiences through coursework and participatory research strategies engaging participants in a range of climate-related investigations. b) Informal science educators and outlets, in particular aquaria and nature centers, as an avenue toward K-12 teacher professional development as well as for public education. c) Regional planning, regulatory and business professionals focused on the built environment along the coasts, many of whom require continuing education to maintain licensing and/or other professional certifications. Our current activities are focused on bringing together an effective set of educational, public- and private-sector partners to target the varied needs of these audiences in Florida and the U.S. Caribbean, and tailoring an educational plan aimed at these stakeholder audiences that starts with the regionally and topically relevant impacts of climate change, and strategies for effective adaptation and

  15. Volatility measurement with directional change in Chinese stock market: Statistical property and investment strategy

    Ma, Junjun; Xiong, Xiong; He, Feng; Zhang, Wei

    2017-04-01

    The stock price fluctuation is studied in this paper with intrinsic time perspective. The event, directional change (DC) or overshoot, are considered as time scale of price time series. With this directional change law, its corresponding statistical properties and parameter estimation is tested in Chinese stock market. Furthermore, a directional change trading strategy is proposed for invest in the market portfolio in Chinese stock market, and both in-sample and out-of-sample performance are compared among the different method of model parameter estimation. We conclude that DC method can capture important fluctuations in Chinese stock market and gain profit due to the statistical property that average upturn overshoot size is bigger than average downturn directional change size. The optimal parameter of DC method is not fixed and we obtained 1.8% annual excess return with this DC-based trading strategy.

  17. Integrated ocean management as a strategy to meet rapid climate change: the Norwegian case.

    Hoel, Alf Håkon; Olsen, Erik

    2012-02-01

    The prospects of rapid climate change and the potential existence of tipping points in marine ecosystems where nonlinear change may result from them being overstepped, raises the question of strategies for coping with ecosystem change. There is broad agreement that the combined forces of climate change, pollution and increasing economic activities necessitates more comprehensive approaches to oceans management, centering on the concept of ecosystem-based oceans management. This article addresses the Norwegian experience in introducing integrated, ecosystem-based oceans management, emphasizing how climate change, seen as a major long-term driver of change in ecosystems, is addressed in management plans. Understanding the direct effects of climate variability and change on ecosystems and indirect effects on human activities is essential for adaptive planning to be useful in the long-term management of the marine environment.

  20. Climate change effects and adaptation strategies in the wine sector: a quantitative literature review

    Sandro Sacchelli

    2016-12-01

    Full Text Available This paper presents a quantitative literature review focusing on how scientific research analysed climate change impact on wine chain as well as potential adaptation strategies. The work is based on content analysis and text mining and takes into account researches from 1990 to 2015. A particular emphasis was given to the evaluation of suggested or implemented adaptation strategies at both global and national levels. Data were analysed using cluster analysis, multidimensional scaling and specificity evaluation. Results show that the study of climate change impacts on the wine sector is a recently emerging research topic. Adaptation strategies have not yet been explored thoroughly in the literature, and in-depth uncertainty quantification is also needed. Finally, additional research gaps and potential future issues are suggested.

  1. Climate Change Adaptation Strategies and Constraints in Northern Ghana: Evidence of Farmers in Sissala West District

    Clifford James Fagariba

    2018-05-01

    Full Text Available Research findings indicate that most African countries are vulnerable to climate change as a result of challenges such as poverty, weather extremes, and insufficient governmental agricultural support. For this reason, the researchers used the Sissala West District as a case study to determine factors influencing farmers’ adaptation to climate change and strategies used to avert climate change impact. A total of 330 small-scale farmers were sampled for survey and 150 key informants were used in focus group discussions. Utilizing the logistic regression model, the study indicated irregular rainfall, high temperature, weather information, and high evaporation as the factors that highly influenced farmers’ ability to adapt to climate change. A Weighted Average Index used to measure weather extremes revealed that drought and temperature had the highest level of occurrence. Furthermore, climate change adaptation strategies assessed in the study showed that agroforestry practices, drought-resistant crops, and mulching were the most preferred methods. The study concluded that farmers’ ability to adapt to climate change can be improved if the Environmental Protection Agency and the Ministry of Food and Agriculture intensify climate adaptation campaigns, increase access to weather information, and train farmers on adaptable strategies including, but not limited to, alternative sources of livelihood.

  2. Leading clinical handover improvement: a change strategy to implement best practices in the acute care setting.

    Clarke, Christina M; Persaud, Drepaul David

    2011-03-01

    Many contemporary acute care facilities lack safe and effective clinical handover practices resulting in patient transitions that are vulnerable to discontinuities in care, medical errors, and adverse patient safety events. This article is intended to supplement existing handover improvement literature by providing practical guidance for leaders and managers who are seeking to improve the safety and the effectiveness of clinical handovers in the acute care setting. A 4-stage change model has been applied to guide the application of strategies for handover improvement. Change management and quality improvement principles, as well as concepts drawn from safety science and high-reliability organizations, were applied to inform strategies. A model for handover improvement respecting handover complexity is presented. Strategies targeted to stages of change include the following: 1. Enhancing awareness of handover problems and opportunities with the support of strategic directions, accountability, end user involvement, and problem complexity recognition. 2. Identifying solutions by applying and adapting best practices in local contexts. 3. Implementing locally adapted best practices supported by communication, documentation, and training. 4. Institutionalizing practice changes through integration, monitoring, and active dissemination. Finally, continued evaluation at every stage is essential. Although gaps in handover process and function knowledge remain, efforts to improve handover safety and effectiveness are still possible. Continued evaluation is critical in building this understanding and to ensure that practice changes lead to improvements in patient safety, organizational effectiveness, and patient and provider satisfaction. Through handover knowledge building, fundamental changes in handover policies and practices may be possible.

  6. Role of media and peers on body change strategies among adult men: is body size important?

    McCabe, Marita P; McGreevy, Shauna J

    2011-01-01

    There has been limited previous research that has examined the role of sociocultural influences on body change strategies among adult men. The current study investigated the role of specific types of messages (encouragement, teasing and modelling) from peers and the media on the strategies to change weight among adult men. Differences were evaluated between 526 men aged from 18 to 60 years from three groups (normal weight, overweight and obese) on body image, body change strategies and messages about their body received from peers and the media. Men were primarily drawn from United States, Australia and Europe. Results showed that messages received by men regarding losing weight or increasing muscle size differed according to weight. Body image and media messages were the strongest predictors of losing weight, whereas body image importance and messages from peers were the strongest predictors of increasing muscles. These findings highlight the importance of sociocultural influences on body change strategies among adult males. Copyright © 2010 John Wiley & Sons, Ltd and Eating Disorders Association.

  9. The effectiveness of strategies to change organisational culture to improve healthcare performance.

    Parmelli, Elena; Flodgren, Gerd; Schaafsma, Mary Ellen; Baillie, Nick; Beyer, Fiona R; Eccles, Martin P

    2011-01-19

    Organisational culture is an anthropological metaphor used to inform research and consultancy and to explain organisational environments. Great emphasis has been placed during the last years on the need to change organisational culture in order to pursue effective improvement of healthcare performance. However, the precise nature of organisational culture in healthcare policy often remains underspecified and the desirability and feasibility of strategies to be adopted has been called into question. To determine the effectiveness of strategies to change organisational culture in order to improve healthcare performance.To examine the effectiveness of these strategies according to different patterns of organisational culture. We searched the following electronic databases for primary studies: The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, Sociological Abstracts, Web of Knowledge, PsycINFO, Business and Management, EThOS, Index to Theses, Intute, HMIC, SIGLE, and Scopus until October 2009. The Database of Abstracts of Reviews of Effectiveness (DARE) was searched for related reviews. We also searched the reference lists of all papers and relevant reviews identified, and we contacted experts in the field for advice on further potential studies. We considered randomised controlled trials (RCTs) or well designed quasi-experimental studies, controlled clinical trials (CCTs), controlled before and after studies (CBAs) and interrupted time series analyses (ITS) meeting the quality criteria used by the Cochrane Effective Practice and Organisation of Care Group (EPOC). Studies should be set in any type of healthcare organisation in which strategies to change organisational culture in order to improve healthcare performance were applied. Our main outcomes were objective measures of professional performance and patient outcome. At least two review authors independently applied the criteria for inclusion and exclusion criteria to scan titles and

  11. Using a social justice and health framework to assess European climate change adaptation strategies.

    Boeckmann, Melanie; Zeeb, Hajo

    2014-11-28

    Climate change puts pressure on existing health vulnerabilities through higher frequency of extreme weather events, changes in disease vector distribution or exacerbated air pollution. Climate change adaptation policies may hold potential to reduce societal inequities. We assessed the role of public health and social justice in European climate change adaptation using a three-fold approach: a document analysis, a critical discourse analysis of a subgroup of strategies, and a ranking of strategies against our social justice framework. The ranking approach favored planning that includes various adaptation types, social issues and infrastructure changes. Themes on values identified in the five subgroup documents showed that risks are perceived as contradictory, technology is viewed as savior, responsibilities need to be negotiated, and social justice is advocated by only a few countries. Of 21 strategy documents assessed overall, those from Austria, England and Sweden received the highest scores in the ranking. Our qualitative assessment showed that in European adaptation planning, progress could still be made through community involvement into adaptation decisions, consistent consideration of social and demographic determinants, and a stronger link between infrastructural adaptation and the health sector. Overall, a social justice framework can serve as an evaluation guideline for adaptation policy documents.

  12. Consultation paper : Nova Scotia's renewed energy strategy and climate change action plan

    2007-10-01

    The Nova Scotia Department of Energy is seeking to create a sustainable and prosperous Nova Scotia that is responsive to climate change. The purpose of this report was to inform public discussion around two upcoming documents, namely the renewed energy strategy focusing on broad energy policy and a climate change action plan for Nova Scotia to reduce greenhouse gas emissions. The report discussed mitigation measures, as it is closely tied with energy use. The consultation process to inform the two documents was to include public forums and direct stakeholder consultation. The report discussed Nova Scotia's strategy for dealing with climate change and the world of energy. Recent changes in energy prices, exploration, awareness, and emerging but uncertain technologies were presented. Long term planning and a review of policy changes were also addressed. The report also presented options for a renewed energy strategy and discussed air quality; energy conservation and efficiency; electricity; natural gas; energy opportunities; government action; and government intervention. Submissions were also sought as input to the discussion paper. refs., tabs., figs., appendices

    2007-01-01

    In natural input modal analysis, only un-scaled mode shapes can be obtained. The mass change method is, in many cases, the simplest way to estimate the scaling factors, which involves repeated modal testing after changing the mass in different points of the structure where the mode shapes are known....... The scaling factors are determined using the natural frequencies and mode shapes of both the modified and the unmodified structure. However, the uncertainty on the scaling factor estimation depends on the modal analysis and the mass change strategy (number, magnitude and location of the masses) used to modify...

    2004-11-01

    The overall purpose of the project was to make a survey of the changes in the Swedish nuclear power plants over the last five years. There is a risk that nuclear power companies after a deregulation will focus especially on reducing operation and maintenance costs and that the changes could have a negative effect on the reactor safety. The task has involved summarising the actual changes, describing the present situation, the need for future development and the differences between the plants as well as identifying possible reactor safety related risks. The survey has been carried out in a broad perspective, studying the changes in equipment, maintenance strategies and the work situation of the staff. Three case studies were carried out at the Swedish nuclear power plants. Documentation from the companies has been analysed and a selection of in total 27 'informed' employees in different positions have been interviewed in total. The project also included a fourth case study concerning railway traffic. This branch of business is interesting because of its longer experience on a deregulated and competitive market. Conclusions concerning the companies individually as well as similarities and differences between them are presented in this report. Results: There have been more changes both in strategy and organisation in the last five years than during the preceding 5-10-year-period and the pace has been relatively rapid. The deregulation of the electricity market was implemented January 1997 and became the main motive force for the changes. The staffing has been reduced or unchanged and the work demands have increased. The maintenance skills have been redistributed within the organisation. New methods and equipment, i.e. RCM, and programmable systems make increased demands for analytical and theoretical competence. In the short term, job satisfaction and motivation have in some cases been negatively influenced by the new organisation forms, according to several of the

  16. Reduced Insecticide Susceptibility in Aedes vexans (Diptera: Culicidae) Where Agricultural Pest Management Overlaps With Mosquito Abatement.

    Mosquito abatement programs in Midwestern communities frequently exist within landscapes dominated by agriculture. Although separately managed, both agricultural pests and mosquitoes are targeted by similar classes of insecticides. As a result, there is the potential for unintended insecticide exposure to mosquito populations from agricultural pest management. To determine the impact that agricultural management practices have on mosquito insecticide susceptibility we compared the mortality of Aedes vexans (Meigen; Diptera: Culicidae) between populations sampled from locations with and without mosquito abatement in South Dakota, a region dominated by agricultural production. Collection locations were either within towns with mosquito abatement programs (n = 2; Brookings and Sioux Falls, SD) or located > 16 km from towns with mosquito abatement programs (n = 2; areas near Harrold and Willow Lake, SD). WHO bioassays were used to test susceptibly of adults to differing insecticide classes relative to their respective controls; 1) an organochlorine (dieldrin 4%), 2) an organophosphate (malathion 5%), and 3) a pyrethroid (lambda-cyhalothrin 0.05%). Corrected mortality did not significantly differ between locations with or without abatement; however, when locations were analized by proportion of developed land within the surrounding landscape pyrethroid mortality was significantly lower where crop production dominated the surrounding landscape and mosquito abatement was present. These data suggest that agricultural pest management may incidentally contribute to reduced mosquito susceptibility where overlap between agricultural pest management and mosquito abatement exists. Decoupling insecticide classes used by both agricultural and public health pest management programs may be necessary to ensure continued efficacy of pest management tools.

  17. Abatement vs. treatment for efficient diffuse source water pollution management in terrestrial-marine systems.

    Roebeling, P C; Cunha, M C; Arroja, L; van Grieken, M E

    2015-01-01

    Marine ecosystems are affected by water pollution originating from coastal catchments. The delivery of water pollutants can be reduced through water pollution abatement as well as water pollution treatment. Hence, sustainable economic development of coastal regions requires balancing of the marginal costs from water pollution abatement and/or treatment and the associated marginal benefits from marine resource appreciation. Water pollution delivery reduction costs are, however, not equal across abatement and treatment options. In this paper, an optimal control approach is developed and applied to explore welfare maximizing rates of water pollution abatement and/or treatment for efficient diffuse source water pollution management in terrestrial-marine systems. For the case of diffuse source dissolved inorganic nitrogen water pollution in the Tully-Murray region, Queensland, Australia, (agricultural) water pollution abatement cost, (wetland) water pollution treatment cost and marine benefit functions are determined to explore welfare maximizing rates of water pollution abatement and/or treatment. Considering partial (wetland) treatment costs and positive water quality improvement benefits, results show that welfare gains can be obtained, primarily, through diffuse source water pollution abatement (improved agricultural management practices) and, to a minor extent, through diffuse source water pollution treatment (wetland restoration).

  18. Soil mapping and processes models to support climate change mitigation and adaptation strategies: a review

    Muñoz-Rojas, Miriam; Pereira, Paulo; Brevik, Eric; Cerda, Artemi; Jordan, Antonio

    2017-04-01

    As agreed in Paris in December 2015, global average temperature is to be limited to "well below 2 °C above pre-industrial levels" and efforts will be made to "limit the temperature increase to 1.5 °C above pre-industrial levels. Thus, reducing greenhouse gas emissions (GHG) in all sectors becomes critical and appropriate sustainable land management practices need to be taken (Pereira et al., 2017). Mitigation strategies focus on reducing the rate and magnitude of climate change by reducing its causes. Complementary to mitigation, adaptation strategies aim to minimise impacts and maximize the benefits of new opportunities. The adoption of both practices will require developing system models to integrate and extrapolate anticipated climate changes such as global climate models (GCMs) and regional climate models (RCMs). Furthermore, integrating climate models driven by socio-economic scenarios in soil process models has allowed the investigation of potential changes and threats in soil characteristics and functions in future climate scenarios. One of the options with largest potential for climate change mitigation is sequestering carbon in soils. Therefore, the development of new methods and the use of existing tools for soil carbon monitoring and accounting have therefore become critical in a global change context. For example, soil C maps can help identify potential areas where management practices that promote C sequestration will be productive and guide the formulation of policies for climate change mitigation and adaptation strategies. Despite extensive efforts to compile soil information and map soil C, many uncertainties remain in the determination of soil C stocks, and the reliability of these estimates depends upon the quality and resolution of the spatial datasets used for its calculation. Thus, better estimates of soil C pools and dynamics are needed to advance understanding of the C balance and the potential of soils for climate change mitigation. Here

    2018-06-01

    Full Text Available As interest in climate change adaptation grows, an increasing number of national and local governments are developing adaptation strategies. This study assesses the strategies for urban climate change adaptation of municipal governments in South Korea. The adaptation plans and budget expenditures of six metropolitan cities in South Korea were compared, based on the Implementation Plan for Climate Change Adaptation Strategy (IPCCAS 2012–2016 and annual expenditure reports of each city. The results show that the actual implementation of these adaptation programs varied vis-à-vis the original plans, in terms of the level of overall expenditure and sector-specific expenditure. The following findings were drawn from the analysis: First, in most cases, the highest adaptation priorities were disaster/infrastructure, water management, and the health sector. Second, actual expenditure on climate change adaptation programs was smaller than the planned budget in the IPCCAS. Third, the prioritized sectors matched for planning and implementation in Seoul, Daegu, Daejeon, and Incheon, but not in Busan and Ulsan. Fourth, the adaptation programs of South Korean metropolitan cities do not seem to have been well-tailored to each case.

  2. Coupled Climate-Economy-Biosphere (CoCEB) model - Part 1: Abatement share and investment in low-carbon technologies

    Ogutu, K. B. Z.; D'Andrea, F.; Ghil, M.; Nyandwi, C.; Manene, M. M.; Muthama, J. N.

    2015-04-01

    The Coupled Climate-Economy-Biosphere (CoCEB) model described herein takes an integrated assessment approach to simulating global change. By using an endogenous economic growth module with physical and human capital accumulation, this paper considers the sustainability of economic growth, as economic activity intensifies greenhouse gas emissions that in turn cause economic damage due to climate change. Different types of fossil fuels and different technologies produce different volumes of carbon dioxide in combustion. The shares of different fuels and their future evolution are not known. We assume that the dynamics of hydrocarbon-based energy share and their replacement with renewable energy sources in the global energy balance can be modeled into the 21st century by use of logistic functions. Various climate change mitigation policy measures are considered. While many integrated assessment models treat abatement costs merely as an unproductive loss of income, we consider abatement activities also as an investment in overall energy efficiency of the economy and decrease of overall carbon intensity of the energy system. The paper shows that these efforts help to reduce the volume of industrial carbon dioxide emissions, lower temperature deviations, and lead to positive effects in economic growth.

  3. Rethinking health systems strengthening: key systems thinking tools and strategies for transformational change.

    While reaching consensus on future plans to address current global health challenges is far from easy, there is broad agreement that reductionist approaches that suggest a limited set of targeted interventions to improve health around the world are inadequate. We argue that a comprehensive systems perspective should guide health practice, education, research and policy. We propose key 'systems thinking' tools and strategies that have the potential for transformational change in health systems. Three overarching themes span these tools and strategies: collaboration across disciplines, sectors and organizations; ongoing, iterative learning; and transformational leadership. The proposed tools and strategies in this paper can be applied, in varying degrees, to every organization within health systems, from families and communities to national ministries of health. While our categorization is necessarily incomplete, this initial effort will provide a valuable contribution to the health systems strengthening debate, as the need for a more systemic, rigorous perspective in health has never been greater.

  4. Changes of Changes: Personal Life Strategy in the Context of Regional Social and Labour Policy: Purchase of Accommodation

    Full Text Available This is the first of three articles in cycle that is dedicated to the regional aspect of change of Russians life strategy in solving the important personal problems like provision of housing, acquisition of income in terms of the profession and merited pension maintenance in the context of the current and prospective changes. The first article concentrates on the solution of housing problem by young Russians and young families. The methods, which are accessible for the citizens of Saratov, were analyzed in terms of the hardest ways without privileges and government support: pledge, housing rent and deposit. The authors presented the digital data on comparison between the popular pledge of OJSC Sberbank and similar ones at the start conditions of housing rent and deposits. Theyve specified the possibility of the reducing time and the amount of payment of the purchased apartment from 20 years, where is the amount of overpayment is 1 850 498, to 4.5-7 years, altogether without overpayments. The basic risks when using discussed ways of the accommodation purchase were demonstrated and specific examples of risks in Saratov were given. There are no absolute priorities when choosing the way of the accommodation purchase, there are examples in the article of a sharp increase of the efficiency within the pledge, and the rent on condition that only one factor has changed. Besides, there are examples of mixed ways including social housing and service housing. Nowadays there is a psychological aspect of the underestimate of the cost-effectively housing rent. As a result we made a conclusion that in spite of the real impossibility to plan and predict the changes, the success of individual strategy of life in solving housing and other important problems depends on the perception and understanding of the changes, on the early use for practical purposes and on the existing life stereotypes.

  5. Enhanced change detection performance reveals improved strategy use in avid action video game players.

    Clark, Kait; Fleck, Mathias S; Mitroff, Stephen R

    2011-01-01

    Recent research has shown that avid action video game players (VGPs) outperform non-video game players (NVGPs) on a variety of attentional and perceptual tasks. However, it remains unknown exactly why and how such differences arise; while some prior research has demonstrated that VGPs' improvements stem from enhanced basic perceptual processes, other work indicates that they can stem from enhanced attentional control. The current experiment used a change-detection task to explore whether top-down strategies can contribute to VGPs' improved abilities. Participants viewed alternating presentations of an image and a modified version of the image and were tasked with detecting and localizing the changed element. Consistent with prior claims of enhanced perceptual abilities, VGPs were able to detect the changes while requiring less exposure to the change than NVGPs. Further analyses revealed this improved change detection performance may result from altered strategy use; VGPs employed broader search patterns when scanning scenes for potential changes. These results complement prior demonstrations of VGPs' enhanced bottom-up perceptual benefits by providing new evidence of VGPs' potentially enhanced top-down strategic benefits.

  6. Comparison of Strategies for Climate Change Adaptation of Water Supply and Flood Control Reservoirs

    Ng, T. L.; Yang, P.; Bhushan, R.

    2016-12-01

    With climate change, streamflows are expected to become more fluctuating, with more frequent and intense floods and droughts. This complicates reservoir operation, which is highly sensitive to inflow variability. We make a comparative evaluation of three strategies for adapting reservoirs to climate-induced shifts in streamflow patterns. Specifically, we examine the effectiveness of (i) expanding the capacities of reservoirs by way of new off-stream reservoirs, (ii) introducing wastewater reclamation to augment supplies, and (iii) improving real-time streamflow forecasts for more optimal decision-making. The first two are hard strategies involving major infrastructure modifications, while the third a soft strategy entailing adjusting the system operation. A comprehensive side-by-side comparison of the three strategies is as yet lacking in the literature despite the many past studies investigating the strategies individually. To this end, we developed an adaptive forward-looking linear program that solves to yield the optimal decisions for the current time as a function of an ensemble forecast of future streamflows. Solving the model repeatedly on a rolling basis with regular updating of the streamflow forecast simulates the system behavior over the entire operating horizon. Results are generated for two hypothetical water supply and flood control reservoirs of differing inflows and demands. Preliminary findings suggest that of the three strategies, improving streamflow forecasts to be most effective in mitigating the effects of climate change. We also found that, in average terms, both additional reservoir capacity and wastewater reclamation have potential to reduce water shortage and downstream flooding. However, in the worst case, the potential of the former to reduce water shortage is limited, and similarly so the potential of the latter to reduce downstream flooding.

  7. Management strategies for coral reefs and people under global environmental change: 25 years of scientific research.

    Comte, Adrien; Pendleton, Linwood H

    2018-03-01

    Coral reef ecosystems and the people who depend on them are increasingly exposed to the adverse effects of global environmental change (GEC), including increases in sea-surface temperature and ocean acidification. Managers and decision-makers need a better understanding of the options available for action in the face of these changes. We refine a typology of actions developed by Gattuso et al. (2015) that could serve in prioritizing strategies to deal with the impacts of GEC on reefs and people. Using the typology we refined, we investigate the scientific effort devoted to four types of management strategies: mitigate, protect, repair, adapt that we tie to the components of the chain of impact they affect: ecological vulnerability or social vulnerability. A systematic literature review is used to investigate quantitatively how scientific effort over the past 25 years is responding to the challenge posed by GEC on coral reefs and to identify gaps in research. A growing literature has focused on these impacts and on management strategies to sustain coral reef social-ecological systems. We identify 767 peer reviewed articles published between 1990 and 2016 that address coral reef management in the context of GEC. The rate of publication of such studies has increased over the years, following the general trend in climate research. The literature focuses on protect strategies the most, followed by mitigate and adapt strategies, and finally repair strategies. Developed countries, particularly Australia and the United States, are over-represented as authors and locations of case studies across all types of management strategies. Authors affiliated in developed countries play a major role in investigating case studies across the globe. The majority of articles focus on only one of the four categories of actions. A gap analysis reveals three directions for future research: (1) more research is needed in South-East Asia and other developing countries where the impacts of

  8. Abatement of mercury pollution in the small-scale gold mining industry: restructuring the policy and research agendas.

    Hilson, Gavin

    2006-06-01

    This paper critiques contemporary research and policy approaches taken toward the analysis and abatement of mercury pollution in the small-scale gold mining sector. Unmonitored releases of mercury from gold amalgamation have caused considerable environmental contamination and human health complications in rural reaches of sub-Saharan Africa, Latin America and Asia. Whilst these problems have caught the attention of the scientific community over the past 15-20 years, the research that has since been undertaken has failed to identify appropriate mitigation measures, and has done little to advance understanding of why contamination persists. Moreover, the strategies used to educate operators about the impacts of acute mercury exposure, and the technologies implemented to prevent further pollution, have been marginally effective at best. The mercury pollution problem will not be resolved until governments and donor agencies commit to carrying out research aimed at improving understanding of the dynamics of small scale gold mining communities. Acquisition of this knowledge is the key to designing and implementing appropriate support and abatement measures.

    Much research on organizational change and middle management has emphasized the idea of flatter more performance- and customer focused organizations, in which middle managers’ main responsibilities concern elements of organizational change and development such as strategy involvement, and managing...... people. An important condition for this is, however, that middle managers also perceive such responsibilities as important. This paper is based on a survey of Managers in Danish organizations. Findings with different but related angels are highlighted here. First, only a small percentage of participating...... managers reported that the amount of managerial levels had actually been reduced in the last three years. Secondly, middle managers who had experienced such a reduction perceived aspects of strategy and organizational development as more important. Thirdly, such a reduction did not introduce significant...

  11. Indoor-atmospheric radon-related radioactivity affected by a change of ventilation strategy

    Kobayashi, Tuneo

    2006-01-01

    The present author has kept observation for concentrations of atmospheric radon, radon progeny and thoron progeny for several years at the campus of Fukushima Medical University. Accidentally, in the midst of an observation term, i.e., February 2005, the facility management group of the university changed a strategy for the manner of ventilation, probably because of a recession: tidy everyday ventilation of 7:30-24:00 into shortened weekday ventilation of 8:00-21:00 with weekend halts. This change of ventilation manner brought a clear alteration for the concentrations of radon-related natural radioactivity in indoor air. The present paper concerns an investigation of the effect of the ventilation strategy on the indoor-atmospheric radon-related radioactivity. (author)

    Clay, R.; Neraasen, T.; Coley, R.

    1991-01-01

    Two significant impacts of climate change could affect waterfowl. Climate changes that induce dryness and reduce surface water would have a detrimental effect on waterfowl production capabilities. Global warming could also increase sea levels and flood critical waterfowl overwintering habitat. Strategies undertaken by Ducks Unlimited, a waterfowl conservation organization, to respond to the threat posed by global warming to waterfowl are reviewed. Ducks Unlimited will continue to assist with wetland restoration and preservation throughout the Great Plains. Strategies to enhance retention include converting marginally arable land to permanent forage, forage backflooding, and encouragement of zero and minimum tillage operations. Improved efficiency of irrigation projects is important to foster water conservation. Widespread surface water drainage should be discouraged, by combinations of legislation and economic incentives. Ducks Unlimited is refocusing its activites on parts of Alberta, Saskatchewan and Manitoba that are likely to have relatively wetter conditions under climatic warming

  13. The economics of controlling stock pollutants: An efficient strategy for greenhouse gases

    Falk, I.; Mendelsohn, R.

    1993-01-01

    Optimal control theory is applied to develop an efficient strategy to control stock pollutants such as greenhouse gases and hazardous waste. The optimal strategy suggests that, at any time, the marginal costs of abatement should be equated with the present value of the marginal damage of timely unabated emission. The optimal strategy calls for increasingly tight abatement over time as the pollutant stock accumulates. The optimal policy applied to greenhouse gases suggest moderate abatement efforts, at present, with the potential for much greater future efforts. 15 refs., 2 tabs

  14. Climate change on the Colorado River: a method to search for robust management strategies

    Keefe, R.; Fischbach, J. R.

    2010-12-01

    The Colorado River is a principal source of water for the seven Basin States, providing approximately 16.5 maf per year to users in the southwestern United States and Mexico. Though the dynamics of the river ensure Upper Basin users a reliable supply of water, the three Lower Basin states (California, Nevada, and Arizona) are in danger of delivery interruptions as Upper Basin demand increases and climate change threatens to reduce future streamflows. In light of the recent drought and uncertain effects of climate change on Colorado River flows, we evaluate the performance of a suite of policies modeled after the shortage sharing agreement adopted in December 2007 by the Department of the Interior. We build on the current literature by using a simplified model of the Lower Colorado River to consider future streamflow scenarios given climate change uncertainty. We also generate different scenarios of parametric consumptive use growth in the Upper Basin and evaluate alternate management strategies in light of these uncertainties. Uncertainty associated with climate change is represented with a multi-model ensemble from the literature, using a nearest neighbor perturbation to increase the size of the ensemble. We use Robust Decision Making to compare near-term or long-term management strategies across an ensemble of plausible future scenarios with the goal of identifying one or more approaches that are robust to alternate assumptions about the future. This method entails using search algorithms to quantitatively identify vulnerabilities that may threaten a given strategy (including the current operating policy) and characterize key tradeoffs between strategies under different scenarios.

    On the 20 October 1990 the joint council of ministers of the environment and energy decided to adopt as a community objective, to fight the greenhouse effect and its consequent climatic change, the establishment of the level of CO[sub 2] emissions in the year 2000 at the levels of 1990. This objective was to be reached by a mixed strategy, comprising control measures at community level, complemented by other actions nationally.

  16. Communicating the Urgency and Challenge of Global Climate Change: Lessons Learned and New Strategies

    Dilling, L.; Moser, S. C.

    2004-12-01

    Climate change can sometimes be characterized as a "creeping environmental problem"--it is complex and long-term, involves long system lags, lacks the immediacy of everyday experience and thus is hard to perceive, and feels overwhelming to most individuals. Climate change thus does not typically attain the status of an urgent concern, taking priority over other matters for individuals, organizations or in the policy arena. We review the major reasons behind this lack of urgency, and document the observed consequences of previous communication strategies, including lack of public understanding, indifference, confusion, fear and uncertainty. We find that certain emotional motivators such as fear and guilt, while oft-employed, do not actually result in improved recognition of the urgency of the issue, nor do they typically result in action. Rather, positive and engaging approaches may be more likely to achieve this goal. We propose seven strategies to improve the communication of climate change and its urgency: 1) Abide by basic communication rules and heed the warnings of communication experts; 2) Address the emotional and the temporal components of "urgency"; 3) Increase the persuasiveness of the message; 4) Use trusted messengers-broaden the circle; 5) Use opportunities well; 6) Tap into individual and cultural strengths and values; and 7) Unite and Conquer. The multi-faceted nature of the proposed strategies reflects the unique challenges of the climate change issue as well as the need to engage all levels and sectors of societies in the solution, from individuals, to businesses, to governments. These strategies and results emerged from a multi-disciplinary, academic/practitioner workshop on the topic held at NCAR in summer 2004.

  17. The effectiveness of strategies to change organisational culture to improve healthcare performance: a systematic review.

    Organisational culture is an anthropological metaphor used to inform research and consultancy and to explain organisational environments. In recent years, increasing emphasis has been placed on the need to change organisational culture in order to improve healthcare performance. However, the precise function of organisational culture in healthcare policy often remains underspecified and the desirability and feasibility of strategies to be adopted have been called into question. The objective of this review was to determine the effectiveness of strategies to change organisational culture in order to improve healthcare performance. We searched the following electronic databases: The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, Sociological Abstracts, Web of Knowledge, PsycINFO, Business and Management, EThOS, Index to Theses, Intute, HMIC, SIGLE, and Scopus until October 2009. The Database of Abstracts of Reviews of Effectiveness (DARE) was searched for related reviews. We also searched the reference lists of all papers and relevant reviews identified, and we contacted experts in the field for advice on further potential studies. We considered randomised controlled trials (RCTs) or well designed quasi-experimental studies (controlled clinical trials (CCTs), controlled before and after studies (CBAs), and interrupted time series (ITS) analyses). Studies could be set in any type of healthcare organisation in which strategies to change organisational culture in order to improve healthcare performance were applied. Our main outcomes were objective measures of professional performance and patient outcome. The search strategy yielded 4,239 records. After the full text assessment, two CBA studies were included in the review. They both assessed the impact of interventions aimed at changing organisational culture, but one evaluated the impact on work-related and personal outcomes while the other measured clinical outcomes. Both were at high risk of

    Anthropogenic habitat fragmentation represents a major obstacle to species shifting their range in response to climate change. Conservation measures to increase the (meta-)population capacity and permeability of landscapes may help but the effectiveness of such measures in a warming climate has rarely been evaluated. Here, we simulate range dynamics of 51 species from three taxonomic groups (vascular plants, butterflies and grasshoppers) in Central Europe as driven by twenty-first-century climate scenarios and analyse how three habitat-based conservation strategies (establishing corridors, improving the landscape matrix, and protected area management) modify species' projected range size changes. These simulations suggest that the conservation strategies considered are unable to save species from regional extinction. For those persisting, they reduce the magnitude of range loss in lowland but not in alpine species. Protected area management and corridor establishment are more effective than matrix improvement. However, none of the conservation strategies evaluated could fully compensate the negative impact of climate change for vascular plants, butterflies or grasshoppers in central Europe.

    2005-05-01

    The oil industry is particularly concerned with the issue of climate change. The implementation of Greenhouse Gases (GHG) reduction policies can be perceived as an additional environmental constraint for the management of the production chain. It is also represents a first step towards a possible decarbonization of the economy. In the long-term, the fight against global warming calls thus into question the activity level of petroleum companies. Confronted with this, still uncertain, new environmental deal, some petroleum multinationals adopt proactive behaviors, e.g. with voluntary commitments to reduce GHG emissions, or with investments in alternative technologies. First of all, we present the potential economic impacts of the Kyoto Protocol on oil industry. Then, we conduct a comparative analysis of the 'Kyoto risk' for the five largest multinationals of this sector according to their activities and their geographical implantations. Then, for the purpose to interpreting proactive strategies of firms such as BP and Shell, we examine various explanations including 'win-win', public image and the response to broad societal needs. This leads us to formalize the proactive behavior as an anticipatory management of carbon contestability, particularly perceptible in financial markets. Lastly, we try to justify economically investments of companies in the field of alternative energy sources and technologies through the lens of real options theory and by a management of the exhaustible fossil resources.

The implementation of Greenhouse Gases (GHG) reduction policies can be perceived as an additional environmental constraint for the management of the production chain. It is also represents a first step towards a possible decarbonization of the economy. In the long-term, the fight against global warming calls thus into question the activity level of petroleum companies. Confronted with this, still uncertain, new environmental deal, some petroleum multinationals adopt proactive behaviors, e.g. with voluntary commitments to reduce GHG emissions, or with investments in alternative technologies. First of all, we present the potential economic impacts of the Kyoto Protocol on oil industry. Then, we conduct a comparative analysis of the 'Kyoto risk' for the five largest multinationals of this sector according to their activities and their geographical implantations. Then, for the purpose to interpreting proactive strategies of firms such as BP and Shell, we examine various explanations including 'win-win', public image and the response to broad societal needs. This leads us to formalize the proactive behavior as an anticipatory management of carbon contestability, particularly perceptible in financial markets. Lastly, we try to justify economically investments of companies in the field of alternative energy sources and technologies through the lens of real options theory and by a management of the exhaustible fossil resources.

  1. The performance challenge: a strategy for change, a strategy for implementation, 1991-1996. Le defi performance: une strategie de changement, une strategie d'implantation, 1991-1996

    1990-11-01

    In the spring of 1990, Hydro-Quebec put into action a plan for change whose objective was to improve overall performance. To carry out this objective, a performance analysis of the company was prepared and strategies were recommended. The analysis showed that performance was unsatisfactory and that comparable companies whose performance has improved have integrated into a coherent system all the elements of management related to their mission, their culture, to the competence of their employees, and to their structures and systems. Hydro-Quebec then decided to adopt a strategy for change which was sufficiently global so that any measures taken for improvement would be integrated into a harmonious, coherent, and well-performing whole. This strategy is based on quality management: total satisfaction at least cost of all the needs of internal and external clients; mastery of work processes; employee mobilization; an orientation toward the customer; management as a function of facts; and respect for the person. To carry out the overall strategy, Hydro-Quebec has formed an action plan which clearly identifies the fields where action is necessary, the actions to be done, and the various stages needed to carry out these actions. Improvement teams are being integrated into this overall strategy. 4 figs.

    After the climate change negotiation reaches an agreement in COP7, the next main issue to be addressed is the way of involvement of developing countries in emission abatement commitments and the development of domestic policies and measures to achieve GHG emission reduction target. Many Annex I countries have developed and implemented policies and measures to achieve its quantified GHG emission reduction target. The purpose of this paper is to propose a portfolio of policies and measures, that is, which policies and measures Korea will have to take in preparing future commitment for GHG emission reduction as well as in strengthening mitigation of climate change. Various policies and measures can be used, such as regulations, economic instruments, and covenants, etc., but it is desirable to implement them in some portfolio, taking advantage of their characteristics. Among the possible policies and measures, this study found that economic instruments such as carbon tax and domestic emissions trading have attracted considerable interest recently due to their cost effectiveness. This study also found that, in practice, many developed countries have used these policy instruments in achieving their quantified GHG emission reduction target. In order to develop a portfolio of policies and measures, the comprehension of the features of each policy and measure and the synergetic reconciliation with other objectives than climate change is important.

    Yijun, Liu; Yu, Fang; Xiaoman, He; Yongyou, Wang

    The general mathematic mode of computing noise abatement is commonly used for most project planning and appraisal of environmental noise abatement projects. However, the inconvenient and impracticable mode and algorithm usually cannot meet the real world computation and testing. Therefore, a more practicable abatement mode and algorithm (multiple noise sources with multiband under sound barriers) which had been applied to VR based simulation system. That implemented the function of real-time demonstrating noise scattering condition within 3D virtual space, furthermore, with sound barriers added in 3D scene, the effectiveness of denoise by sound barriers also can be demonstrated within this system. That provides a significant solution for environmental noise abatement projects as a whole.

  7. Climate Change and Energy Sustainability. Which Innovations in European Strategies and Plans

    2014-05-01

    Full Text Available In recent years, the effects of climate change on urban areas have pushed more and more policy-makers and urban planners to deal with the management of territorial transformations in a systemic and multi-sector perspective, due to the complexity of the issue. In order to enhance the urban governance of climate change and cope with environmental sustainability, the concept of resilience can be used. In this perspective, the present work has a double purpose: on the one hand to reflect on he need to adopt a new comprehension/interpretive approach to the study of the city, which embraces the concept of resilience, and on the other hand to perform a reading of European strategies and plans oriented to mitigate the effects of climate change and to achieve the goals of energy and environmental sustainability. This paper describes some of the results of the knowledge framework of the Project Smart Energy Master for the energy management of territory financed by PON 04A2_00120 R & C Axis II, from 2012 to 2015 aimed at supporting local authorities in the development of strategies for the reduction of energy consumption through actions designed to change behavior (in terms of use and energy consumption and to improve the energy efficiency of equipment and infrastructure. The paper is divided into three parts: the first is oriented to the definition of the new comprehension/interpretive approach; the second illustrates a series of recent innovations in planning tools of some European States due to the adoption of the concept of resilience; the third, finally, describes and compares the most innovative energy and environmental strategies aimed at contrasting and/or mitigate the effects of climate change, promoted in some European and Italian cities.

  8. Ethical implications of co-benefits rationale within climate change mitigation strategy

    Rita Vasconcellos Oliveira

    2016-10-01

    Full Text Available Climate change mitigation effort is being translated into several actions and discourses that make collateral benefits and their rationale increasingly relevant for sustainability, in such a way that they are now a constant part of the political agenda. Taking a border and consensual perspective, co-benefits are considered here to be emerging advantages of the implementation of measures regarding the lowering of greenhouse gases.Departing from the analysis of policy documents referring to two European urban transportation strategies, the emergent co-benefits are problematized and discussed to better understand their moral aspect. Further ethical reflection is conducted after an analysis of some unintended consequences of co-benefits rationale coming from the mentioned examples. The focus is primarily on the challenges of an integrative moral justification for co-benefits and also for their role in the climate change mitigation effort. We also discuss the limitations of the current normative models that frame co-benefits rationale, from a moral viewpoint and in relation to the overall climate change mitigation strategy.In this article, we propose the concepts of well-being and freedom, as portrayed by Capabilities Approach, as possible guiding notions for the moral and social evaluation of goodness of these emergent benefits and their rationale too. Additionally, some preliminary conclusions are drawn regarding the potential of the presented concepts to favour the climate change mitigation action. Finally, a scenario is drawn where Capabilities Approach is the moral guideline for co-benefits rationale showing this way its potential in terms of enhancing climate change mitigation strategy.

    Ammonia emissions from livestock production can have negative impacts on nearby protected sites and ecosystems that are sensitive to eutrophication and acidification. Trees are effective scavengers of both gaseous and particulate pollutants from the atmosphere making tree belts potentially effective landscape features to support strategies aiming to reduce ammonia impacts. This research used the MODDAS-THETIS a coupled turbulence and deposition turbulence model, to examine the relationships between tree canopy structure and ammonia capture for three source types—animal housing, slurry lagoon, and livestock under a tree canopy. By altering the canopy length, leaf area index, leaf area density, and height of the canopy in the model the capture efficiencies varied substantially. A maximum of 27% of the emitted ammonia was captured by tree canopy for the animal housing source, for the slurry lagoon the maximum was 19%, while the livestock under trees attained a maximum of 60% recapture. Using agro-forestry systems of differing tree structures near ‘hot spots’ of ammonia in the landscape could provide an effective abatement option for the livestock industry that complements existing source reduction measures.

    1998-02-01

    The proposed Biological Monitoring and Abatement Program (BMAP) for East Fork Poplar Creek (EFPC) at the Oak Ridge Y-12 Plant, as described, will be conducted for the duration of the National Pollutant Discharge Elimination System permit issued for the Y-12 Plant on April 28, 1995, and which became effective July 1, 1995. The basic approach to biological monitoring used in this program was developed by the staff in the Environmental Sciences Division at the Oak Ridge National Laboratory at the request of Y-12 Plant personnel. The proposed BMAP plan is based on results of biological monitoring conducted since 1985. Details of the specific procedures used in the current routine monitoring program are provided, but experimental designs for future studies are described in less detail. The overall strategy used in developing this plan was, and continues to be, to use the results obtained from each task to define the scope of future monitoring efforts. Such efforts may require more intensive sampling than initially proposed in some areas or a reduction in sampling intensity in others. By using the results of previous monitoring efforts to define the current program and to guide them in the development of future studies, an effective integrated monitoring program has been developed to assess the impacts of the Y-12 Plant operation on the biota of EFPC and to document the ecological effects of remedial actions.

  11. Photocatalytic NO{sub x} abatement. Theory, applications, current research, and limitations

    2017-01-15

    Nitrogen oxides are one of the major air pollutants that threaten our air quality and health. As a consequence, increasingly stricter regulations are in place forcing action to reduce the concentration of these dangerous compounds. Conventional methods of reducing the NO{sub x} pollution level are reducing the emission directly at the source or restrictive measures such as low emission zones. However, there are recent reports questioning the efficacy of the strategy to reduce ambient NO{sub x} levels solely by reducing their emissions and existing threshold values are still frequently exceeded in many European cities. Semiconductor photocatalysis presents an appealing alternative capable of removing NO{sub x} and other air pollutants from the air once they have already been released and dispersed. Recent field tests have shown that a reduction of a few percent in NO{sub x} values is possible with available photocatalysts. Current research focuses on further increasing the catalysts' efficacy as well as their selectivity to suppress the formation of undesired by-products. Especially using these improved materials, photocatalytic NO{sub x} abatement could prove a very valuable contributor to better air quality.

    2010-01-01

    Traditional odor control methods are limitative technically and economically for the abatement of odor from pesticide factory due to its toxicity and complicated composition. Non-thermal plasma (NTP) methods, typically characterized by high removal efficiency, energy yields and good economy, offer possible alternative solutions. This paper provides laboratory scale experimental data on the removal of simulated odors from pesticide factory with various humidity (0-0.8 vol%) and oxygen contents (0-21%) by a dielectric barrier discharge (DBD) reactor. Peak voltage and initial dimethylamine (DML) concentration are important factors that influence the DML removal efficiency and energy yield. The conversion of DML of 761 mg/m 3 reaches 100% at a peak voltage of 41.25 kV. Under the experiment conditions, the conversion of DML increases with an increase of oxygen contents. And the highest DML conversion was achieved with the gas stream containing 0.3% water. Simultaneously, the concentration of O 3 and OH radical in reactor was measured. Higher conversion, higher energy yield and fewer byproducts were found in mixed odor (DML + dimethyl sulfide (DMS)) treatment than that in single odor treatment. The energy yield is promoted from 2.13 to 5.20 mg/kJ.

  15. Solar energy and the abatement of atmospheric emissions

    Mirasgedis, S.; Diakoulaki, D.; Assimacopoulos, D.

    1996-01-01

    In spite of the fact that solar energy is a ''clean'' energy form, gaseous pollutants are emitted during the manufacturing of the systems necessary for its utilisation. An attempt is made in this paper to estimate the level of atmospheric pollutants emitted during the successive stages which make up the manufacture process for solar water heating (SWH) systems, and to evaluate these results in comparison with the respective pollutant emission levels attributed to the generation of electricity in Greece's conventional power plants. As energy consumption is recognised as the main source of atmospheric pollution, a Life Cycle Analysis (LCA) method was applied, focusing on the most energy-consuming stages of the SWH system production process. The conclusions of the analysis indicate that the emissions of gaseous pollutants associated with the utilisation of solar energy are considerably lower than those caused by the production of electricity in conventional systems, thereby substantiating that solar energy utilisation can make a notable contribution to the abatement of atmospheric pollution.

  16. Renewable energy and CO_2 abatement in Italy

    Marcantonini, Claudio; Valero, Vanessa

    2017-01-01

    In order to combat global warming, Italy has committed to reduce its CO_2 emissions. To this end, it has significantly encouraged renewable energy development through a variety of support schemes, ranging from green certificates to feed-in and premium tariffs. As a result, the production of electricity from renewable energy sources, in particular from solar and wind energy, has risen considerably over the past years. In this paper we review the Italian support schemes for wind and solar energy and estimate the cost of abating CO_2 emissions by generating electricity from these two sources of energy for the period 2008–2011. The results show that the average costs for wind were around 165 €/tCO_2. For solar, they were much higher, around 1000 €/tCO_2, as solar energy received much higher remunerations than wind energy. These costs were much higher than in Germany. This was due to the differences between the level of incentives and the different power systems. - Highlights: • We estimate the cost of reducing CO_2 emissions by wind and solar energy in Italy in 2008–2011. • The average costs for wind were around 165 €/tCO_2. • The average costs for solar were much higher, around 1000 €/tCO_2. • Those costs were much higher than in Germany. • This was due to the differences in the levels of incentives and to the different power systems.

    Full Text Available Implementing the management of madrasah change starts from an authentic leadership. Authentic leadership is the identity of a head of madrasah in developing value-based educational system. His identity is seen from his sincerity in working, his kindness in treating people and the sharpness of his mind in determining the future of the organization. The authentic leadership of madrasah should represent the identity of moslem morality with work orientation on the sincerity of being a STAF+B (Siddiq, Tablig, Amanah, Fathonah + Brave leader. Leading the madrasah in the context of implementing management of change is not enough to be pious but it requires courage to take strategic and innovative decisions in realizing a qualified madrasah. This research aims to find an authentic leadership strategy model for management of change by head of madrasah. The research was conducted on the head of madrasah in Pangandaran Regency. The results show that the application of authentic leadership can build madrasah changes by empowering the Professional Learning Community (PLC in which 4CS strategy is implemented in a reciprocal (cumsuis-Casing, Communicating, Competencies, Contribution, Sample. The followers can identify who the authentic leader is by finding the integrity of identity that represents in: his mind is vision; his heart is good and his legs work hard.

    African Americans with high blood pressure (BP) can benefit greatly from therapeutic lifestyle changes (TLC) such as diet modification, physical activity, and weight management. However, they and their health care providers face many barriers in modifying health behaviors. A multidisciplinary panel synthesized the scientific data on TLC in African Americans for efficacy in improving BP control, barriers to behavioral change, and strategies to overcome those barriers. Therapeutic lifestyle change interventions should emphasize patient self-management, supported by providers, family, and the community. Interventions should be tailored to an individual's cultural heritage, beliefs, and behavioral norms. Simultaneously targeting multiple factors that impede BP control will maximize the likelihood of success. The panel cited limited progress with integrating the Dietary Approaches to Stop Hypertension (DASH) eating plan into the African American diet as an example of the need for more strategically developed interventions. Culturally sensitive instruments to assess impact will help guide improved provision of TLC in special populations. The challenge of improving BP control in African Americans and delivery of hypertension care requires changes at the health system and public policy levels. At the patient level, culturally sensitive interventions that apply the strategies described and optimize community involvement will advance TLC in African Americans with high BP.

  20. Classical Ecological Restoration and its Current Challenges: Assisted Migration as an Adaptation Strategy to Climate Change

    Pilar A. Gómez-Ruiz

    2017-06-01

    Full Text Available Ecological restoration is a very active area in ecology and of great importance for ecosystems management. Despite of being a relatively young discipline, the classical concepts of restoration seem, at present, impractical considering the great challenges generated by modification and destruction of ecosystems. This is due to anthropic activities (deforestation, change of land use, pollution and global climate change. In the classic definition of restoration, the objective is to recover the degraded ecosystem to the same conditions of a historical reference state. However, nowadays the ecosystems return to a state prior to the disturbances seems unviable, because the thresholds of resilience have already been overcome. Additionally, climate change is causing environmental changes at an unprecedented rate. For this reason, ecological restoration needs to unite efforts of diverse actors to recover ecosystems that can be sustainable and functional in the future, where the species could be able to tolerate the environmental conditions that will exist in the long term. Assisted migration has been proposed as a conservation strategy; it is defined as the translocation of species to new locations outside their known range of distribution. In the current context of loss of diversity and ecosystems, this strategy could be fundamental for the formation of new communities that can later become novel ecosystems where species that are fundamental to the dynamics of ecosystems can persist and, at the same time, recover function, structure and resilience.

  1. Facilitating behavioral learning and habit change in voice therapy--theoretic premises and practical strategies.

    Iwarsson, Jenny

    2015-12-01

    A typical goal of voice therapy is a behavioral change in the patient's everyday speech. The SLP's plan for voice therapy should therefore optimally include strategies for automatization. The aim of the present study was to identify and describe factors that promote behavioral learning and habit change in voice behavior and have the potential to affect patient compliance and thus therapy outcome. Research literature from the areas of motor and behavioral learning, habit formation, and habit change was consulted. Also, specific elements from personal experience of clinical voice therapy are described and discussed from a learning theory perspective. Nine factors that seem to be relevant to facilitate behavioral learning and habit change in voice therapy are presented, together with related practical strategies and theoretical underpinnings. These are: 1) Cue-altering; 2) Attention exercises; 3) Repetition; 4) Cognitive activation; 5) Negative practice; 6) Inhibition through interruption; 7) Decomposing complex behavior; 8) The 'each time-every time' principle; and 9) Successive implementation of automaticity.

  2. Climate Change Adaptation Strategies and Farm-level Efficiency in Food Crop Production in Southwestern, Nigeria

    Otitoju, MA.

    2014-01-01

    Full Text Available Food crop yields depend largely on prevailing climate conditions, especially in Africa, where rain-fed agriculture predominate. The extent to which climate impacts are felt depends principally on the adaptation measures used by farmers. This study focused on the effect of climate change adaptation strategies on farm-level technical efficiency. The study used primary data collected from 360 randomly selected farmers in Southwest Nigeria. Cobb-Douglass stochastic frontier production model was used to analyse the data. Multiple cropping, land fragmentation, multiple planting dates, mulching and cover cropping were the major climate change adaptation strategies employed by the farmers. While land fragmentation and multiple planting dates had significant positive relationships, years of climate change awareness and social capital had significant inverse relationships, with technical inefficiency. This may be because while land fragmentation may hinder farm mechanization, multiple planting dates may increase the monotonousness and drudgery of farming. On the other hand, social capital and climate change awareness could help ameliorate the effects of, particularly, land fragmentation through resource pooling. It is therefore recommended that the farmers be encouraged to form cooperative societies so as to leverage their resource status through collective efforts.

  3. Marginal abatement cost curve for nitrogen oxides incorporating controls, renewable electricity, energy efficiency, and fuel switching.

    Loughlin, Daniel H; Macpherson, Alexander J; Kaufman, Katherine R; Keaveny, Brian N

    2017-10-01

    A marginal abatement cost curve (MACC) traces out the relationship between the quantity of pollution abated and the marginal cost of abating each additional unit. In the context of air quality management, MACCs are typically developed by sorting control technologies by their relative cost-effectiveness. Other potentially important abatement measures such as renewable electricity, energy efficiency, and fuel switching (RE/EE/FS) are often not incorporated into MACCs, as it is difficult to quantify their costs and abatement potential. In this paper, a U.S. energy system model is used to develop a MACC for nitrogen oxides (NO x ) that incorporates both traditional controls and these additional measures. The MACC is decomposed by sector, and the relative cost-effectiveness of RE/EE/FS and traditional controls are compared. RE/EE/FS are shown to have the potential to increase emission reductions beyond what is possible when applying traditional controls alone. Furthermore, a portion of RE/EE/FS appear to be cost-competitive with traditional controls. Renewable electricity, energy efficiency, and fuel switching can be cost-competitive with traditional air pollutant controls for abating air pollutant emissions. The application of renewable electricity, energy efficiency, and fuel switching is also shown to have the potential to increase emission reductions beyond what is possible when applying traditional controls alone.

  4. How large a carbon tax is justified by the secondary benefits of CO2 abatement?

    Ekins, Paul

    1996-01-01

    The combustion of fossil fuels emits a range of damaging pollutants, the emissions of which are reduced if fossil fuel use is reduced in order to achieve CO 2 abatement. These reductions are termed the secondary benefits of such abatement. The paper reviews estimates of the size of these benefits at current levels of emissions of the relevant pollutants. Although the estimates are few and uncertain, their mid-range suggests that the secondary benefits are of the same order of magnitude as the gross costs of medium to high levels of CO 2 abatement, and are substantially larger than the (equally uncertain) estimates of the primary benefits of CO 2 abatement, except where these benefits derive from consideration of damages from unabated global warming in the very long term. The paper then reviews these calculations in the light of the limits on SO 2 emissions mandated by the Second Sulphur Protocol (SSP). It finds that the secondary benefits from abating SO 2 alone beyond the limits of the SSP still provide a substantial offset to the costs of a carbon tax. The paper concludes that the existence of significant secondary benefits greatly reinforces the economic case for an aggressive policy of CO 2 abatement

    Difficulty in emotion regulation is a hallmark feature of patients with borderline personality disorder (BPD). Therefore, change in the frequency of certain patients' coping strategies-aiming at emotion regulation-are among the most promising mechanisms of change in treatments for BPD. In parallel, it was highlighted that therapist responsiveness significantly contributed to outcome across treatment approaches (Stiles, 2009). Based on a randomized controlled trial (Kramer et al., 2014), the present process-outcome mediation analysis aims at examining the patient's early change in frequency of coping strategies-in particular the decrease in behavioral forms of coping-as potential mechanism of change in responsive treatments for BPD. A total of 57 patients with BPD were included in the present analysis, out of whom 27 were randomly assigned to a 10-session psychiatric treatment and 30 to a 10-session psychiatric treatment augmented with the responsive intervention of the motive-oriented therapeutic relationship (Caspar, 2007). The 1st, 5th, and 9th session of each therapy were transcribed and analyzed using the Coping Action Pattern Rating Scale (Perry et al., 2005; 171 sessions analyzed in total), a validated observer-rated method for assessing coping strategies in the therapy process. Psychological distress was assessed using the OQ-45 at intake, after Session 5, and after Session 10. The results confirmed a responsiveness effect associated with the motive-oriented therapeutic relationship and showed a significant decrease in frequency of behavioral forms of coping, F(1, 54) = 3.09, p = .05, d = .56, which was not different between the 2 conditions. In addition, we demonstrated that the early decrease in behavioral forms of coping between Sessions 1 and 5 partially mediated the link between the group assignment and the change in psychological distress between Sessions 5 and 10. These results shed light on the centrality of therapist responsiveness in treatments for

  6. One Health – a strategy for resilience in a changing arctic

    Full Text Available The circumpolar north is uniquely vulnerable to the health impacts of climate change. While international Arctic collaboration on health has enhanced partnerships and advanced the health of inhabitants, significant challenges lie ahead. One Health is an approach that considers the connections between the environment, plant, animal and human health. Understanding this is increasingly critical in assessing the impact of global climate change on the health of Arctic inhabitants. The effects of climate change are complex and difficult to predict with certainty. Health risks include changes in the distribution of infectious disease, expansion of zoonotic diseases and vectors, changing migration patterns, impacts on food security and changes in water availability and quality, among others. A regional network of diverse stakeholder and transdisciplinary specialists from circumpolar nations and Indigenous groups can advance the understanding of complex climate-driven health risks and provide community-based strategies for early identification, prevention and adaption of health risks in human, animals and environment. We propose a regional One Health approach for assessing interactions at the Arctic human–animal–environment interface to enhance the understanding of, and response to, the complexities of climate change on the health of the Arctic inhabitants.

  7. Interactive effects of environmental change and management strategies on regional forest carbon emissions.

    2013-11-19

    Climate mitigation activities in forests need to be quantified in terms of the long-term effects on forest carbon stocks, accumulation, and emissions. The impacts of future environmental change and bioenergy harvests on regional forest carbon storage have not been quantified. We conducted a comprehensive modeling study and life-cycle assessment of the impacts of projected changes in climate, CO2 concentration, and N deposition, and region-wide forest management policies on regional forest carbon fluxes. By 2100, if current management strategies continue, then the warming and CO2 fertilization effect in the given projections result in a 32-68% increase in net carbon uptake, overshadowing increased carbon emissions from projected increases in fire activity and other forest disturbance factors. To test the response to new harvesting strategies, repeated thinnings were applied in areas susceptible to fire to reduce mortality, and two clear-cut rotations were applied in productive forests to provide biomass for wood products and bioenergy. The management strategies examined here lead to long-term increased carbon emissions over current harvesting practices, although semiarid regions contribute little to the increase. The harvest rates were unsustainable. This comprehensive approach could serve as a foundation for regional place-based assessments of management effects on future carbon sequestration by forests in other locations.

  8. Modeling change in learning strategies throughout higher education: a multi-indicator latent growth perspective.

    2013-01-01

    The change in learning strategies during higher education is an important topic of research in the Student Approaches to Learning field. Although the studies on this topic are increasingly longitudinal, analyses have continued to rely primarily on traditional statistical methods. The present research is innovative in the way it uses a multi-indicator latent growth analysis in order to more accurately estimate the general and differential development in learning strategy scales. Moreover, the predictive strength of the latent growth models are estimated. The sample consists of one cohort of Flemish University College students, 245 of whom participated in the three measurement waves by filling out the processing and regulation strategies scales of the Inventory of Learning Styles--Short Versions. Independent-samples t-tests revealed that the longitudinal group is a non-random subset of students starting University College. For each scale, a multi-indicator latent growth model is estimated using Mplus 6.1. Results suggest that, on average, during higher education, students persisting in their studies in a non-delayed manner seem to shift towards high-quality learning and away from undirected and surface-oriented learning. Moreover, students from the longitudinal group are found to vary in their initial levels, while, unexpectedly, not in their change over time. Although the growth models fit the data well, significant residual variances in the latent factors remain.

    2006-12-01

    Full Text Available This paper describes the implementation of an e-learning strategy at a single higher education institution in terms of the levers used to promote effective uptake and ensure sustainable embedding. The focus of this work was at the level of the academic school using a range of change practices including the appointment of school-based learning technologists and e-learning champions, supporting schools to write their own strategies, a pedagogical framework of engaging with e-learning, and curriculum development and evaluation of school-supported projects. It is clear that the implementation of the e-learning strategy has led to a large and increasing proportion of our students experiencing blended learning. In addition, there are initial indications that this has enhanced some learning and teaching processes. Where there has been sustainable embedding of effective e-learning, the following levers were identified as particularly important: flexibility in practices that allow schools to contextualise their plans for change, the facilitation of communities of key staff and creating opportunities for staff to voice and challenge their beliefs about e-learning.

  11. Adapting to climate change in forest based land use systems: A guide to strategy

    Secrett, C M

    1997-12-31

    The prospect of climate change and sea level rise as a result of greenhouse gas emissions presents a serious challenge to decision-makers concerned with ensuring sustainable development. This report provides a guide to means of reducing the potential impact of the global warming problem on the forest sector whilst ensuring that more immediate development priorities are met. The most effective response strategy will be one that simultaneously brings both immediate development and longer-term adaptive benefits. This report outlines ways of constructing an adaptive response strategy that can help achieve these ends. The approach is referred to as sustainable adaptation. A prototype methodological framework of the sustainable adaptation approach has been provided with the summary. The first priority of sustainable adaption is to base climate change responses on actions that meet basic ecological and social needs now and in the future. Solutions should necessarily include relieving current development pressures in the tropical forest sector. The key is to couple adaptive responses to climate change with sustainable development solutions to present-day forest use problems. Implementing adaptive land-use policies and management practices which are likely to minimise the adverse impacts of anticipated climate change should meet current sustainable management goals. Implementing sustainable land-use and forestry management practices should meet adaptation goals. This report presents a discussion of the fundamental issues underlying the development of a sustainable adaptation strategy and a prototype methodological framework. The findings are based on case studies conducted in Central America (Costa Rica and Nicaragua); SADCC countries in Africa (Zimbabwe, Botswana, Tanzania); and Asia (Vietnam). 450 refs

  13. Rhetorical Strategies of Consumer Activists: Reframing Market Offers to Promote Change

    Daiane Scaraboto

    2013-10-01

    Full Text Available Consumer researchers have most frequently looked at the influence the marketplace has on consumers’ identity projects, while the reverse process – how consumers’ identity projects influence the marketplace and general culture – is an important issue that has received less attention. Aiming to contribute to the development of this literature, we conduct a qualitative netnographic investigation of the Fat Acceptance Movement, an online-based movement led by consumer-activists who attempt to change societal attitudes about people who are fat. Our main goal is, therefore, to investigate how consumer activists who congregate online, that is, cyberactivists, reframe market offers while attempting to promote market and cultural change. We identify several rhetorical strategies employed by online consumer activists in their quests to change themselves, other consumers, and the broader culture. Our findings advance consumer research on how consumers may mobilize resources to initiate and promote self-, market-, and cultural transformations.

  14. Self-employed nurses as change agents in healthcare: strategies, consequences, and possibilities.

    Wall, Sarah

    2014-01-01

    The purpose of this paper is to report on ethnographic research that investigated how self-employed nurses perceive the contemporary healthcare field, what attributes they possess that facilitate their roles as change agents, what strategies they use to influence change, and what consequences they face for their actions, thus contributing to what is known about organizational change in institutionalized settings such as healthcare. Focussed ethnography was used to explore self-employed nurses' work experiences and elucidate the cultural elements of their social contexts, including customs, ideologies, beliefs, and knowledge and the ways that these impact upon the possibilities for change in the system. These self-employed nurses reflected on the shortcomings in the healthcare system and took entrepreneurial risks that would allow them to practice nursing according to their professional values. They used a number of strategies to influence change such as capitalizing on opportunities, preparing themselves for innovative work, managing and expanding the scope of nursing practice, and building new ideas on foundational nursing knowledge and experience. They had high job satisfaction and a strong sense of contribution but they faced significant resistance because of their non-traditional approach to nursing practice. Despite dramatic restructuring in the Canadian healthcare system, the system remains physician-centered and hospital-based. Nursing's professional potential has been largely untapped in any change efforts. Self-employed nurses have positioned themselves to deliver care based on nursing values and to promote alternative conceptions of health and healthcare. This study offers a rare exploration of this unique form of nursing practice and its potential to influence health system reform.

  15. Understanding the relationship of maternal health behavior change and intervention strategies in a Nicaraguan NGO network.

    Valadez, Joseph J; Hage, Jerald; Vargas, William

    2005-09-01

    Few studies of community interventions examine independent effects of investments in: (1) capital (i.e., physical, human and social capital), and (2) management systems (e.g., monitoring and evaluation systems (M&E)) on maternal and child health behavior change. This paper does this in the context of an inter-organizational network. In Nicaragua, international non-governmental organizations (NGOs) and local NGOs formed the NicaSalud Federation. Using Lot Quality Assurance Sampling (LQAS), 14 member organizations took baselines measures of maternal safe motherhood and child health behavior indicators during November 1999 and August 2000, respectively, and final evaluation measures in December 2001. In April 2002, retrospective interviews were conducted with supervisors and managers in the 14 organizations to explore changes made to community health strategies, factors associated with the changes, and impacts they attributed to participating in NicaSalud. Physical capital (density of health huts), human capital (density and variety of paramedical personnel) and social capital (density of health committees) were associated with pregnant women attending antenatal care (ANC) 3+ times, and/or retaining ANC cards. The variety of paramedic personnel was also associated with women making post-partum visits to clinics. Physical capital (density of health huts) and social capital (density of health committees and mothers' clubs) were associated with child diarrhea case management indicators. One safe motherhood indicator (delivery of babies by a clinician) was not associated with intervention strategies. At the management level, NicaSalud's training of members to use LQAS for M&E was associated with the number of strategic and tactical changes they subsequently made to interventions (organizational learning). Organizational learning was related to changes in maternal and child health behaviors of the women (including changes in the proportion using post-partum care). As the

    Many classical studies suggest that punishment is a useful way to promote cooperation in the well-mixed public goods game, whereas relative evidence in the research of spatial prisoner’s dilemma game is absent. To address this issue, we introduce a mechanism of strategy changing penalty, combining memory and penalty during the update process, into spatial prisoner’s dilemma game. We find that increasing penalty rate or memory length is able to promote the evolution of cooperation monotonously. Compared with traditional version, recorded penalty could facilitate cooperation better. Moreover, through examining the process of evolution, we provide an interpretation for this promotion phenomenon, namely, the effect of promotion can be warranted by an evolution resonance of standard deviation of fitness coefficient. Finally, we validate our results by studying the impact of uncertainty within strategy adoptions on the evolution of cooperation. We hope that our work may shed light on the understanding of the cooperative behavior in the society.

  17. Regional adaptation strategies to climate change: Guidelines for urban planning in Serbia

    Maruna Marija

    2012-01-01

    Full Text Available The problems of climate change significantly alter the character of urban planning. While changes in the planning process are aimed at mechanisms for urgent action in the transformed circumstances in the sense of a deeper understanding of the causes of phenomena and prediction of future changes, modification of specific measures suppose to be related to the regulatory framework for new and existing construction that will lead to reduction in carbon dioxide emissions and the development of resistance to settlements' extreme impacts. The focus has shifted to land-use planning and the development and application of building regulations. It is considered that planning at the local level is an appropriate instrument for solving the problem of climate impacts in the community. In general, urban planning is an instrument of implementation of national strategies for mitigation and adaptation at the local level. Successful implementation of the strategy is based on a developed vertical and horizontal institutional and procedural coordination. In the circumstances of specific context of post-socialist urban restructuring, which is characterized by a lack of developed institutions and appropriate procedures, it is difficult to expect the entire application of prescribed procedures and harmonization of vertical and horizontal spatial development policies. Accordingly, it is recommended that policies be aimed at short-term improvements that are based on existing climate risk management and short-term projections of climate impacts. Among the main recommendations of the regional climate change adaptation strategies related to policy-makers in the field of urban development is to establish new and efficient use of existing legislation in the field of environment and planning. It is believed that most countries in the region have adequate legislation and efforts should be directed towards more effective implementation of existing planning and building

  18. Climate change, adaptation strategies and mobility: evidence from four settlements in Senegal

    This research investigates the impact of climate change on the mobility of people in four settlements in Senegal: Ngueye Ngueye, Gandiole, the Senegal River delta and Ourossogui. A qualitative approach involving semi-structured interviews and focus groups was used to determine how daily life in these communities is being affected by environmental change. Some migrants spend long periods as far afield as Mauritania, the Gambia or Spain, while others stay closer to home, going to places like Saint-Louis, Dakar and Mbour for short periods. Mobility is an opportunity for migrants to generate funds and send money home. It is a key factor in adaptation to climate change, as a strategy for survival and for diversifying incomes. The problems encountered in the ecological study zones are not entirely due to climate change, for migration is also triggered by factors such as the opening of the breach in Saint-Louis or lack of support for rural development. However, climate change is certainly accelerating disruptions and transformations in the study sites. Moreover, while migrants' financial transfers help improve daily life for some families, they also increase socio-economic inequalities between households that include migrants and those that do not. People are moving away from (but not necessarily abandoning) purely agricultural livelihoods and seeking to diversify their sources of income. This may come from migration, or from artisanal activities undertaken in the locality - such as metalwork, woodwork, sewing or hairdressing. Another option that many women have taken is using micro-credit facilities to start processing local produce, crushing groundnuts and preparing cereals to sell at the weekly markets. Other adaptation strategies are developed and adopted through technical innovations or awareness-raising and educational activities. These activities often require institutional support from the State or from NGOs involved in implementing projects and helping

  19. Coping with child hunger in Canada: have household strategies changed over a decade?

    2012-11-05

    To determine if household coping strategies for child hunger in Canada have changed over a decade (1996-2007). We applied t-tests to data derived from Cycle 2 (1996-1997; n=8165) and Cycle 7 (2006-2007; n=15,961) of the National Longitudinal Survey of Children and Youth (NLSCY) to determine changes in household coping strategies for child hunger. Data were restricted to households with children aged 2-9 years, allowing for cross-sectional analysis of two independent samples. Logistic regression was employed to estimate the odds of reporting child hunger for socio-demographic characteristics and the odds of using different coping strategies. The national prevalence of child hunger fell from 1.5% in 1997 to 0.7% in 2007 (phunger (increased child age and household size, lack of home ownership, low household income, lone-parent status, family dysfunction) and hunger frequency (regular versus occasional) were similar in both NLSCY cycles. Utilization of food banks and other community resources as a method of coping with child hunger remained static despite an increase in national food banks/affiliated agencies in Canada (2,141 in 1998 to 3,540 in 2007). In contrast, there was an increased reliance on reducing household food variety, an internal coping mechanism, to manage child hunger (17.6% Cycle 2 to 35.1% Cycle 7; p=0.03). Community outreach programs between 1997 and 2007 had little impact on coping strategies utilized by households facing child hunger. Our results indicate that current initiatives fail to reach these families.

  20. Envisioning Adaptive Strategies to Change: Participatory Scenarios for Agropastoral Semiarid Systems in Nicaragua

    Federica Ravera

    2011-03-01

    Full Text Available Historically, the semiarid social-ecological systems of the dry Central American corridor have proven resilient to pressures. However, in the last century, these systems have experienced huge environmental and socioeconomic changes that have increased the vulnerability of local livelihoods to shocks. New approaches are needed to capture complex, uncertain, cross-scale and nonlinear relationships among drivers of change and vulnerability. Therefore, to tackle this challenge, we have applied a participatory and interdisciplinary methodological framework of vulnerability assessment to a case study in northern Nicaragua. We triangulated a range of information and data from participatory and scientific research to explore historical and current drivers of changes that affect the system's components and indicators of vulnerability, represented in a 3-dimensional space in terms of ecological resilience, the socioeconomic ability of individuals to adapt to change, and an institutional capacity to buffer and respond to crisis. A projection of climatic changes combined with a participatory scenario analysis helped, then, to heuristically analyze tendencies of vulnerability in the future and to explore what policy options might enhance the system's adaptive capacity to face new pressures. Our work primarily contributes to an empirical understanding of key factors that influence vulnerability and learning about local strategies to adapt to change in semiarid agropastoral systems in Central America. We also make a methodological contribution by testing the use of a multidimensional vulnerability framework as a way of stimulating discussion among researchers, local stakeholders, and policy makers.

  1. Efficient local behavioral-change strategies to reduce the spread of epidemics in networks

    Bu, Yilei; Gregory, Steve; Mills, Harriet L.

    2013-10-01

    It has recently become established that the spread of infectious diseases between humans is affected not only by the pathogen itself but also by changes in behavior as the population becomes aware of the epidemic, for example, social distancing. It is also well known that community structure (the existence of relatively densely connected groups of vertices) in contact networks influences the spread of disease. We propose a set of local strategies for social distancing, based on community structure, that can be employed in the event of an epidemic to reduce the epidemic size. Unlike most social distancing methods, ours do not require individuals to know the disease state (infected or susceptible, etc.) of others, and we do not make the unrealistic assumption that the structure of the entire contact network is known. Instead, the recommended behavior change is based only on an individual's local view of the network. Each individual avoids contact with a fraction of his/her contacts, using knowledge of his/her local network to decide which contacts should be avoided. If the behavior change occurs only when an individual becomes ill or aware of the disease, these strategies can substantially reduce epidemic size with a relatively small cost, measured by the number of contacts avoided.

  2. Influence of smallholder farmers’ perceptions on adaptation strategies to climate change and policy implications in Zimbabwe

    Jiri Obert

    2017-01-01

    Full Text Available Smallholder agricultural production is largely affected by climate change and variability. Despite the negative effects brought by climate variability, smallholder farmers are still able to derive livelihoods. An understanding of factors that influence farmers’ responses and adaptation to climate variability can improve decision making for governments and development partners. This study investigated farmers’ perceptions and adaptation strategies to climate change and how these influence adaptation policies at local level. A survey was conducted with 100 households randomly selected from Chiredzi district. Data collected was used to derive farmer perceptions to climate change as well as the influence of their perceptions and subsequent adaptation methods to ensuing local agricultural adaptation measures and policies. The results indicated that smallholder farmers perceived general reduction in long-term annual rainfall and rising local average temperatures. Adverse trends in rainfall and average temperature perceived by farmers were consistent with empirical data. These perceptions and other socio-economic factors helped to shape smallholder farmer agricultural adaptation strategies. Policy implications are that the government and development partners should seek ways to assist autonomous adaptations by farmers through investments in planned adaptation initiatives.

  3. Assessment of impact of climate change and adaptation strategies on maize production in Uganda

    Kikoyo, Duncan A.; Nobert, Joel

    2016-06-01

    Globally, various climatic studies have estimated a reduction of crop yields due to changes in surface temperature and precipitation especially for the developing countries which is heavily dependent on agriculture and lacks resources to counter the negative effects of climate change. Uganda's economy and the wellbeing of its populace depend on rain-fed agriculture which is susceptible to climate change. This study quantified the impacts of climate change and variability in Uganda and how coping strategies can enhance crop production against climate change and/or variability. The study used statistical methods to establish various climate change and variability indicators across the country, and uses the FAO AquaCrop model to simulate yields under possible future climate scenarios with and without adaptation strategies. Maize, the most widely grown crop was used for the study. Meteorological, soil and crop data were collected for various districts representing the maize growing ecological zones in the country. Based on this study, it was found that temperatures have increased by up to 1 °C across much of Uganda since the 1970s, with rates of warming around 0.3 °C per decade across the country. High altitude, low rainfall regions experience the highest level of warming, with over 0.5 °C/decade recorded in Kasese. Rainfall is variable and does not follow a specific significant increasing or decreasing trend. For both future climate scenarios, Maize yields will reduce in excess of 4.7% for the fast warming-low rainfall climates but increase on average by 3.5% for slow warming-high rainfall regions, by 2050. Improved soil fertility can improve yields by over 50% while mulching and use of surface water management practices improve yields by single digit percentages. The use of fertilizer application needs to go hand in hand with other water management strategies since more yields as a result of the improved soil fertility leads to increased water stress, especially

    Gregersen, Ida Bülow; Arnbjerg-Nielsen, Karsten

    2012-01-01

    Several extraordinary rainfall events have occurred in Denmark within the last few years. For each event, problems in urban areas occurred as the capacity of the existing drainage systems were exceeded. Adaptation to climate change is necessary but also very challenging as urban drainage systems...... are characterized by long technical lifetimes and high, unrecoverable construction costs. One of the most important barriers for the initiation and implementation of the adaptation strategies is therefore the uncertainty when predicting the magnitude of the extreme rainfall in the future. This challenge is explored...

  6. Combating the effects of climatic change on forests by mitigation strategies

    Dieter Matthias

    2010-11-01

    Full Text Available Abstract Background Forests occur across diverse biomes, each of which shows a specific composition of plant communities associated with the particular climate regimes. Predicted future climate change will have impacts on the vulnerability and productivity of forests; in some regions higher temperatures will extend the growing season and thus improve forest productivity, while changed annual precipitation patterns may show disadvantageous effects in areas, where water availability is restricted. While adaptation of forests to predicted future climate scenarios has been intensively studied, less attention was paid to mitigation strategies such as the introduction of tree species well adapted to changing environmental conditions. Results We simulated the development of managed forest ecosystems in Germany for the time period between 2000 and 2100 under different forest management regimes and climate change scenarios. The management regimes reflect different rotation periods, harvesting intensities and species selection for reforestations. The climate change scenarios were taken from the IPCC's Special Report on Emission Scenarios (SRES. We used the scenarios A1B (rapid and successful economic development and B1 (high level of environmental and social consciousness combined with a globally coherent approach to a more sustainable development. Our results indicate that the effects of different climate change scenarios on the future productivity and species composition of German forests are minor compared to the effects of forest management. Conclusions The inherent natural adaptive capacity of forest ecosystems to changing environmental conditions is limited by the long life time of trees. Planting of adapted species and forest management will reduce the impact of predicted future climate change on forests.

  7. Implant Strategy-Specific Changes in Symptoms in Response to Left Ventricular Assist Devices.

    Lee, Christopher S; Gelow, Jill M; Chien, Christopher V; Hiatt, Shirin O; Bidwell, Julie T; Denfeld, Quin E; Grady, Kathleen L; Mudd, James O

    Although we know that the quality of life generally improves after left ventricular assist device (LVAD) implantation, we know little about how symptoms change in response to LVAD. The purpose of this study was to compare the changes in symptoms between bridge and destination therapy patients as part of a prospective cohort study. Physical (dyspnea and wake disturbances) and affective symptoms (depression and anxiety) were measured before LVAD and at 1, 3, and 6 months after LVAD. Multiphase growth modeling was used to capture the 2 major phases of change: initial improvements between preimplant and 1 month after LVAD and subsequent improvements between 1 and 6 months after LVAD. The sample included 64 bridge and 22 destination therapy patients as the preimplant strategy. Destination patients had worse preimplant dyspnea and wake disturbances, and they experienced greater initial improvements in these symptoms compared with bridge patients (all P .05). Destination patients had worse preimplant depression (P = .042) but experienced similar initial and subsequent improvements in depression in response to LVAD compared with bridge patients (both P > .05). Destination patients had similar preimplant anxiety (P = .279) but experienced less initial and greater subsequent improvements in anxiety after LVAD compared with bridge patients (both P < .05). There are many differences in the magnitude and timing of change in symptom responses to LVAD between bridge and destination therapy patients. Detailed information on changes in specific symptoms may better inform shared decision-making regarding LVAD.

  8. Culturally compelling strategies for behaviour change: a social ecology model and case study in malaria prevention.

    Panter-Brick, Catherine; Clarke, Sian E; Lomas, Heather; Pinder, Margaret; Lindsay, Steve W

    2006-06-01

    Behaviour change is notoriously difficult to initiate and sustain, and the reasons why efforts to promote healthy behaviours fail are coming under increasing scrutiny. To be successful, health interventions should build on existing practices, skills and priorities, recognise the constraints on human behaviour, and either feature community mobilisation or target those most receptive to change. Furthermore, interventions should strive to be culturally compelling, not merely culturally appropriate: they must engage local communities and nestle within social and ecological landscapes. In this paper, we propose a social ecology perspective to make explicit the links between intention to change, actual behaviour change, and subsequent health impact, as relating to both theory-based models and practical strategies for triggering behaviour change. A social ecology model focuses attention on the contexts of behaviour when designing, implementing or critically evaluating interventions. As a case study, we reflect on a community-directed intervention in rural Gambia designed to reduce malaria by promoting a relatively simple and low-cost behaviour: repairing holes in mosquito bednets. In phase 1, contextual information on bednet usage, transactions and repairs (the 'social lives' of nets) was documented. In phase 2 (intervention), songs were composed and posters displayed by community members to encourage repairs, creating a sense of ownership and a compelling medium for the transmission of health messages. In phase 3 (evaluation), qualitative and quantitative data showed that household responses were particularly rapid and extensive, with significant increase in bednet repairs (psocial ecology-of behaviour practices that are the bedrock of health interventions.

    Cities are increasingly taking actions such as building code enforcement, urban planning, and public transit expansion to reduce emissions of carbon dioxide in their communities and municipal operations. However, many cities lack the quantitative information needed to estimate policy impacts and prioritize city actions in terms of carbon abatement potential and cost effectiveness. This report fills this research gap by providing methodologies to assess the carbon abatement potential of a variety of city actions. The methodologies are applied to an energy use data set of 23,458 cities compiled for the U.S. Department of Energy’s City Energy Profile tool. The analysis estimates the national carbon abatement potential of the most commonly implemented actions in six specific policy areas. The results of this analysis suggest that, in aggregate, cities could reduce nationwide carbon emissions by about 210 million metric tons of carbon dioxide (MMT CO2) per year in a "moderate abatement scenario" by 2035 and 480 MMT CO2/year in a "high abatement scenario" by 2035 through these common actions typically within a city’s control in the six policy areas. The aggregate carbon abatement potential of these specific areas equates to a reduction of 3%-7% relative to 2013 U.S. emissions. At the city level, the results suggest the average city could reduce carbon emissions by 7% (moderate) to 19% (high) relative to current city-level emissions. City carbon abatement potential is sensitive to national and state policies that affect the carbon intensity of electricity and transportation. Specifically, the U.S. Clean Power Plan and further renewable energy cost reductions could reduce city carbon emissions overall, helping cities achieve their carbon reduction goals.

    1. General observations Africa south of the Sahara is probably the most vulnerable region when it comes to the impact and consequences of climate changes. Yet the African continent runs a serious risk of being marginalized in the global dialogue on climate issues. Africa contributes little to the global emissions of CO2, and other greenhouse gases. The major focus of the Framework Convention on Climate Change is on abatement and mitigation of emissions rather than adaptation to the con...

  11. Contextualising change through a common strategy: Lecturers' perceptions and key role in supporting academic reform

    Kindelan, Paz; Martin, Ana

    2014-05-01

    European universities are currently going through a process of change in order to meet the common goals set for higher education by the European Commission. They are revising their educational models to adjust them to the guidelines of the "Bologna Process" and are devising an institutional strategy for its implementation. In practical terms, this means aligning former national degrees and diplomas to standard European Bachelor and Masters degrees and PhD doctorates, by creating acknowledged professional qualification benchmarks that also include adjusted course lengths and contents. This process, in the end, mostly affects academic staff members who have a fundamental role to play in carrying out the pedagogical reforms on the teaching front. Besides presenting a commentary on the institutional approach of one particular technical university in Spain, the purpose of this paper is to propose, from the authors' point of view as lecturers, a strategy which has the potential to create a favourable atmosphere for carrying out such a reform. The article's main objective is to highlight a series of action points which may serve to reinforce and advance the main institutional strategy by relying on the powerful influence of its academic staff members.

  12. The impact of climate change on the strategies of the electricity industry

    2000-01-01

    This report is a compilation of the results of a questionnaire survey conducted among eight companies from the E7 and six electricity companies outside the E7, investigating how each company, within its own particular circumstances, deals with the climate change issue as a business issue, and the specific actions that are being taken by major electric companies to alleviate the effect of greenhouse gas emissions. In doing this survey, the E7 companies expect that the results demonstrate the role of electricity as an important means to reduce greenhouse gas emissions, the seriousness with which electric companies in both Annex I and non-Annex I countries view climate change mitigation measures as an important aspect of their corporate strategies, and the extent of cooperation among companies in the electricity sector worldwide as an effective and practical approach to reducing greenhouse gas emissions. 7 refs., 6 tabs., 11 figs

A series of 109 patients with stable angina pectoris and at least one occluded coronary...... a discrepancy in 22% of the patients, resulting in a lower or higher number of grafts than pre-operatively estimated. The difference in shift rates between the three sites, left anterior descending, left circumflex, and right coronary artery, was significant (P=0.014). Patency rates were highest when only...... preoperatively planned grafts were inserted. When shifts occurred, no matter in which direction, it resulted in a decreased patency rate of the inserted grafts. This finding was significant for LAD (P=0.037).

    Full Text Available Climate change and variability are a threat to sustainable agricultural production in semi-arid areas of Malawi. Overdependence on subsistence rain-fed agriculture in these areas calls for the identification of sustainable adaptation strategies. A study was therefore conducted in Chikwawa, a semi-arid district in southern Malawi, to: (1 assess community’s perception of a changing climate against empirical evidence, (2 determine their local adaptive measures, (3 evaluate the potential of irrigated agriculture as an adaptive measure in household food security and (4 challenges over access to available water resources. The study employed focus group discussions and key informant interviews to assess people’s perceptions of climate change and variability and their desired interventions. To validate the people’s perceptions, rainfall and temperature data for the period 1960–2010 were analysed. A participatory complete randomised experimental design in both rain-fed and dry season–irrigated conditions was conducted to assess a maize cropping system that would improve adaptation. The study established persistent declining yields from rain-fed production in part because of perennial rainfall failure. In response, the community has shifted its focus to irrigation as an adaptation strategy, which has in turn triggered water conflicts in the community over the control of the resource. Water legislation however fails to adequately provide for rules governing sharing of water resources between various stakeholders. This article therefore recommends development of an appropriate institutional framework that forms a strong basis for equitable distribution of water for irrigation in areas most vulnerable to extreme climate events – including droughts and floods.

  15. Scenarios Simulation of Spatio-Temporal Land Use Changes for Exploring Sustainable Management Strategies

    Yu Zhang

    2018-03-01

    Full Text Available Land use and land cover change have received considerable attention from global researchers in recent decades. The conflicts between different development strategies for land uses have become a problem that urgently needs to be solved, especially in those regions with a fragile ecological environment. The development of scenario simulations is essential in order to highlight possible alternative pathways for the future under the backgrounds of urbanization, economic growth and ecological protection. This study simulated land use changes for Tekes in 2020 with the Conversion of Land Use and its Effects at Small regional extent (CLUE-S model under a ‘business as usual’ scenario, cropland protection scenario, ecological security scenario, and artificial modification scenario. The results indicated that the spatial patterns of the land use types were explained well by the environment variables, and the selected models had a satisfactory accuracy in this study. The requirements and the patterns were quite different owing to the variation of the major objectives of the four scenarios. In addition to the constraint rules of the land use transformation, the hot point for land use change was its spatial coherency. Areas near to an existing land use type were more likely to transform to that type than those farther away. The increased cropland and urban land were mainly located around the current cropland and urban land while forests and grassland were more likely to occur in places with flat terrain and good hydrological conditions. The results could contribute to better insight into the relationships between land use changes and their driving factors and provide a scientific basis for regional management strategies and sustainable land use development.

  16. Teaching strategies and conceptual change in a professional development program for science teachers of K--8

    Shen, Ji

    This case study investigates two consecutive science courses for teachers of K-8 in a professional development program at Washington University. It aims (1) to trace the processes of the teachers' conceptual change; (2) to analyze the teaching strategies by course instructors; and (3) to try to establish possible links between the two. To achieve this goal, I build a modeling theory to account for the observations. The main body of the study consists of four sub-cases. The first two cases instantiate the elements of the modeling theory. The opening case of balance shows that learning tools and task structures shape the learning outcome, and discusses cycles of modeling. The case also delineates the strategy that the instructors employed---moving from concrete experience to abstract explanation. The second case of buoyancy demonstrates that the modeling theory is able to explain the origins and forming mechanism of the alternative conceptions held by the teachers. It also shows that the teaching strategies of using alternative conceptions, applying analogies and following a logical sequence helped the teachers build new models. The last two cases demonstrate the ways of improving the competence of modelers. The third case of physical models emphasizes the metacognition of the learner who builds models. It illustrates that teachers' level of self-awareness in learning is increased when the models are physical. It shows that the creativity of modeling is rooted in agency, curiosity, communicability, and confidence, and that a chain of transformation among models is the key of systematizing and forming knowledge. The last case of frames of reference tries to answer the question "what is the justification of models if there are alternatives?" The teachers employed different forms of justification which relied heavily on common sense, authority, relativism, and pragmatism, all of which are not rational. While discussing both the positive and negative traits of these

    Different structural and functional changes take place during leaf development. Since some of them are highly connected to oxidative metabolism, regulation of reactive oxygen species (ROS) abundance is required. Most of the reactive oxygen species ROS in plant cells are produced in chloroplasts as a result of highly energetic reactions of photosynthesis. The aim of our study was to examine the changes in concentration of oxidative stress parameters (TBARS - thiobarbituric acid-reacting substances and protein carbonyls) as well as antioxidative strategies during development of maple (Acer platanoides L.) leaves in the light of their enhanced photosynthetic performance. We reveal that biogenesis of the photosynthetic apparatus during maple leaf maturation corresponded with oxidative damage of lipids, but not proteins. In addition, antioxidative responses in young leaves differed from that in older leaves. Young leaves had high values of non-photochemical quenching (NPQ) and catalase (CAT, EC 1.11.1.6) activity which declined during the maturation process. Developing leaves were characterized by an increase in TBARS level, the content of non-enzymatic antioxidants as well as ascorbate peroxidase activity (APX, EC 1.11.1.11), while the content of protein carbonyls decreased with leaf maturation. Fully developed leaves had the highest lipid peroxidation level accompanied by a maximum in ascorbic acid content and superoxide dismutase activity (SOD, EC1.15.1.1). These observations imply completely different antioxidative strategies during leaf maturation enabling them to perform their basic function. Copyright © 2011 Elsevier Masson SAS.

    Adaptation is the process whereby a population or species becomes better fitted to its habitat through modifications of various life history traits which can be positively or negatively correlated. The molecular factors underlying these covariations remain to be elucidated. Using Saccharomyces cerevisiae as a model system, we have investigated the effects on life history traits of varying the dosage of genes involved in the transformation of resources into energy. Changing gene dosage for each of three glycolytic enzyme genes (hexokinase 2, phosphoglucose isomerase, and fructose-1,6-bisphosphate aldolase) resulted in variation in enzyme activities, glucose consumption rate, and life history traits (growth rate, carrying capacity, and cell size). However, the range of effects depended on which enzyme was expressed differently. Most interestingly, these changes revealed a genetic trade-off between carrying capacity and cell size, supporting the discovery of two extreme life history strategies already described in yeast populations: the "ants," which have lower glycolytic gene dosage, take up glucose slowly, and have a small cell size but reach a high carrying capacity, and the "grasshoppers," which have higher glycolytic gene dosage, consume glucose more rapidly, and allocate it to a larger cell size but reach a lower carrying capacity. These results demonstrate antagonist pleiotropy for glycolytic genes and show that altered dosage of a single gene drives a switch between two life history strategies in yeast.

  20. Spot market natural gas strategies and reliability dealing with changing industry conditions

    McClure, D.C.

    1992-01-01

    Many in the energy industry thought the natural gas buying game had finally settled down to a predictable pattern in the 90's. After a tumultuous decade in the 80's they are ready to turn their attention to new challenges such as electricity wheeling and cogeneration. They were wrong. There is plenty of change left in the natural gas industry for the rest of the century. This growth will dramatically increase the number of options available to Energy Buyers, giving them new flexibility to design programs that meet goals for cost reduction, supply reliability, and administrative effort. However, with new options also come the responsibility for choices. Energy Managers of well designed gas programs will make these choices after careful consideration of the pro's and con's of each option. In short, the effective Buyer will develop a natural gas strategy. This report will begin by reviewing the basic types of change occurring in the industry, and then discuss some of the varied strategy options available to the Energy Buyer

    Climate projections produced with CMIP5 and applied by the Intergovernmental Panel on Climate Change (IPCC) in its fifth assessment report indicate that changes in precipitation and temperature are expected to occur throughout Europe in the 21th century, with a likely decrease of water availability in many regions. Besides, water demand is also expected to increase, in link with these expected climate modifications, but also due to socio-economic and demographic changes. In this respect, the use of future freshwater resources may not be sustainable from the current water management perspective. Therefore adaptation strategies will most likely be needed to cope with these evolutions. In this context, the main objective of the ClimAware project (2010-2013 - www.uni-kassel.de/fb14/wasserbau/CLIMAWARE/, a project implemented within the IWRM-NET Funding Initiative) was to analyse the impacts of climate change (CC) on freshwater resources at the continental and regional scales and to identify efficient adaptation strategies to improve water management for various socio-economic sectors. This should contribute to a more effective implementation of the Water Framework Directive (WFD) and its instruments (river basin management plans, programmes of measures). The project developed integrated measures for improved freshwater management under CC constraints. More specifically, the objectives of the ClimAware project were to: • elaborate quantitative projections of changes in river flows and consequences such as flood frequency, drought occurrence and sectorial water uses. • analyse the effect of CC on the hydromorphological reference conditions of rivers and therefore the definition of "good status". • define management rules/strategies concerning dam management and irrigation practices on different time perspectives. • investigate uncertainties in climate model - scenario combinations. The research approach considered both European and regional perspectives, to get

  4. Climate change and eHealth: a promising strategy for health sector mitigation and adaptation

    Åsa Holmner

    2012-06-01

    Full Text Available Climate change is one of today's most pressing global issues. Policies to guide mitigation and adaptation are needed to avoid the devastating impacts of climate change. The health sector is a significant contributor to greenhouse gas emissions in developed countries, and its climate impact in low-income countries is growing steadily. This paper reviews and discusses the literature regarding health sector mitigation potential, known and hypothetical co-benefits, and the potential of health information technology, such as eHealth, in climate change mitigation and adaptation. The promising role of eHealth as an adaptation strategy to reduce societal vulnerability to climate change, and the link's between mitigation and adaptation, are also discussed. The topic of environmental eHealth has gained little attention to date, despite its potential to contribute to more sustainable and green health care. A growing number of local and global initiatives on ‘green information and communication technology (ICT’ are now mentioning eHealth as a promising technology with the potential to reduce emission rates from ICT use. However, the embracing of eHealth is slow because of limitations in technological infrastructure, capacity and political will. Further research on potential emissions reductions and co-benefits with green ICT, in terms of health outcomes and economic effectiveness, would be valuable to guide development and implementation of eHealth in health sector mitigation and adaptation policies.

  6. Dynamic modelling of water demand, water availability and adaptation strategies for power plants to global change

    Koch, Hagen; Voegele, Stefan

    2009-01-01

    According to the latest IPCC reports, the frequency of hot and dry periods will increase in many regions of the world in the future. For power plant operators, the increasing possibility of water shortages is an important challenge that they have to face. Shortages of electricity due to water shortages could have an influence on industries as well as on private households. Climate change impact analyses must analyse the climate effects on power plants and possible adaptation strategies for the power generation sector. Power plants have lifetimes of several decades. Their water demand changes with climate parameters in the short- and medium-term. In the long-term, the water demand will change as old units are phased out and new generating units appear in their place. In this paper, we describe the integration of functions for the calculation of the water demand of power plants into a water resources management model. Also included are both short-term reactive and long-term planned adaptation. This integration allows us to simulate the interconnection between the water demand of power plants and water resources management, i.e. water availability. Economic evaluation functions for water shortages are also integrated into the water resources management model. This coupled model enables us to analyse scenarios of socio-economic and climate change, as well as the effects of water management actions. (author)

  8. Dental work force strategies during a period of change and uncertainty.

    Brown, L J

    2001-12-01

    Both supply and demand influence the ability of the dental work force to adequately and efficiently provide dental care to a U.S. population growing in size and diversity. Major changes are occurring on both sides of the dental care market. Among factors shaping the demand for dental care are changing disease patterns, shifting population demographics, the extent and features of third-party payment, and growth of the economy and the population. The capacity of the dental work force to provide care is influenced by enhancements of productivity and numbers of dental health personnel, as well as their demographic and practice characteristics. The full impact of these changes is difficult to predict. The dentist-to-population ratio does not reflect all the factors that must be considered to develop an effective dental work force policy. Nationally, the dental work force is likely to be adequate for the next several years, but regional work force imbalances appear to exist and may get worse. Against this backdrop of change and uncertainty, future dental work force strategies should strive for short-term responsiveness while avoiding long-term inflexibility. Trends in the work force must be continually monitored. Thorough analysis is required, and action should be taken when necessary.

    2015-12-01

    Full Text Available In Indonesia, the climate change and the global warming like changes in the pattern and distribution of the rainfall give impacts on agricultural production at large, especially in the food crops. These also cause droughts, floods, landslides, forest fires, rising temperatures in urban areas, and rising sea levels. The above impacts are felt by the farmers because those can lead to a decrease in production even the crop failure. This research aims to develop an empowerment strategy of the food crop farmers in anticipating the climate change in Central Java. The data used is the primary data obtained through in-depth interviews with key-person and the Focus Group Discussion (FGD. The Analysis Hierarchy Process (AHP is conducted to determine the program priorities and strate gies. The result of research shows that anticipating the climate change should be synergistically conducted in four aspects: human resources, technology, institutional and production, by involving various groups in the society. Various groups can be grouped into academics, businessmen / private sectors, government and community of food crop farmers / society.

  10. Values under seige in Mexico: strategies for sheltering traditional values from change.

    Hubbell, L J

    1993-01-01

    The adverse economic conditions of inflation and falling oil prices over the late 1970s and 1980s in Mexico forced many middle-class married women out of the home and into the workplace in order to help the family maintain its socioeconomic standing. Although this phenomenon ran directly against the traditional Mexican cultural construction of gender and family, many Uruapan middle-class couples had no alternative and rationalized the change by concealing, reinterpreting, or not directly challenging traditional values. Sections discuss the dilemma of middle-class families, Mexican middle-class adaptation to wives' employment, strategies for existing change in values, and the open acceptance of changed values. The author's comments and conclusions are based largely upon interviews with 16 married women of the period. It is concluded that even though the middle class resists them, changes have taken place over the past 20 years in the acceptance of married women in the workplace, the sharing of domestic work, fertility control, and equality between spouses in family decision making. It remains to be seen, however, whether these women will stop working and return to their formerly exclusive roles of wives and mothers if and when economic conditions improve in Mexico.

  11. A Health Care Project Management Office's Strategies for Continual Change and Continuous Improvement.

    Lavoie-Tremblay, Mélanie; Aubry, Monique; Richer, Marie-Claire; Cyr, Guylaine

    Health care organizations need project and change management support in order to achieve successful transformations. A project management office (PMO) helps support the organizations through their transformations along with increasing their capabilities in project and change management. The aim of the present study was to extend understanding of the continuous improvement mechanisms used by PMOs and to describe PMO's strategies for continual change and continuous improvement in the context of major transformation in health care. This study is a descriptive case study design with interviews conducted from October to December 2015 with PMO's members (3 managers and 1 director) and 3 clients working with the PMO after a major redevelopment project ended (transition to the new facility). Participants suggested a number of elements including carefully selecting the members of the PMO, having a clear mandate for the PMO, having a method and a discipline at the same time as allowing openness and flexibility, clearly prioritizing projects, optimizing collaboration, planning for everything the PMO will need, not overlooking organizational culture, and retaining the existing support model. This study presents a number of factors ensuring the sustainability of changes.

    1991-01-01

    Despite considerable efforts for air pollution abatement - examples are here desulphurization and nitrogen removal in power and large combustion plants as well as catalytic converters for automobiles there are still many problems to solve. Many small and medium-size companies still have to reduce production-related pollutant emissions, traffic still is a major source of pollutants. Air pollution abatement in the new Federal states and other Eastern European countries is a particularly urgent task and reductions of CO 2 emissions from energy production processes with fossil fuels are not least a great challenge. Apart from industry, legislation and administration especially science is called upon to find solutions to these problems. The university of Stuttgart takes up the challenge. Numerous institutes - 17 of 8 faculties -united in the working group ''air pollution abatement'' of the university of Stuttgart which carries out in interdisciplinary cooperation research work in the area of air pollution abatement. In this annual report activities of individual member states institutes in the area of air pollution abatement (fields of study, current research projects, cooperations and publications in 1991) as well as joint projects are presented.

  13. Abatement of waste gases and water during the processes of semiconductor fabrication.

    Wen, Rui-mei; Liang, Jun-wu

    2002-10-01

    The purpose of this article is to examine the methods and equipment for abating waste gases and water produced during the manufacture of semiconductor materials and devices. Three separating methods and equipment are used to control three different groups of electronic wastes. The first group includes arsine and phosphine emitted during the processes of semiconductor materials manufacture. The abatement procedure for this group of pollutants consists of adding iodates, cupric and manganese salts to a multiple shower tower (MST) structure. The second group includes pollutants containing arsenic, phosphorus, HF, HCl, NO2, and SO3 emitted during the manufacture of semiconductor materials and devices. The abatement procedure involves mixing oxidants and bases in an oval column with a separator in the middle. The third group consists of the ions of As, P and heavy metals contained in the waste water. The abatement procedure includes adding CaCO3 and ferric salts in a flocculation-sedimentation compact device equipment. Test results showed that all waste gases and water after the abatement procedures presented in this article passed the discharge standards set by the State Environmental Protection Administration of China.

  14. Changes in motor unit recruitment strategy during pain alters force direction.

    Tucker, Kylie J; Hodges, Paul W

    2010-10-01

    Motor unit (MU) recruitment is altered (decreased discharge rate and cessation of discharge in some units, and recruitment of new units) in force-matched contractions during pain compared to contractions performed before pain. As MU's within a motoneurone pool have different force direction properties we hypothesised that altered MU recruitment during experimental knee pain would change the force vector (total force (F(T)): amplitude and angle) generated by the quadriceps. Force was produced at two levels during 1 × 60-s and 3 × 10-s isometric contractions of knee extensors, and recorded by two force transducers at right angles. This enabled calculation of both F(E) (extension force) and F(T). MU recruitment was recorded from the medial and lateral vastii with four fine-wire electrodes. Pain was induced by hypertonic saline injection in the infra-patella fat pad. Nine subjects matched F(E) and six subjects also matched both medial and lateral forces (F(T)) before and during pain. Changes in MU discharge pattern (decreased discharge rate (Precruitment of new units) during pain were associated with a ∼5° change in absolute force angle. As force angle changed in both directions (left/right) for individual subjects with pain there was no change in average F(T) amplitude between conditions. When both medial and lateral forces were matched MU discharge rate decreased (Punits ceased firing or were newly recruited during pain. Change in motoneurone recruitment during pain alters direction of muscle force. This may be a strategy to avoid pain or protect the painful part.

    Lawrence Berkeley National Laboratory (LBL) is working with the California Energy Commission (CEC) to determine the role of distributed generation (DG) in greenhouse gas reductions. The impact of DG on large industrial sites is well known, and mostly, the potentials are already harvested. In contrast, little is known about the impact of DG on commercial buildings with peak electric loads ranging from 100 kW to 5 MW. We examine how DG with combined heat and power (CHP) may be implemented within the context of a cost minimizing microgrid that is able to adopt and operate various smart energy technologies, such as thermal and photovoltaic (PV) on-site generation, heat exchangers, solar thermal collectors, absorption chillers, and storage systems. We use a mixed-integer linear program (MILP) that has the minimization of a site's annual energy costs as objective. Using 138 representative commercial sites in California (CA) with existing tariff rates and technology data, we find the greenhouse gas reduction potential for California's commercial sector. This paper shows results from the ongoing research project and finished work from a two year U.S. Department of Energy research project. To show the impact of the different technologies on CO2 emissions, several sensitivity runs for different climate zones within CA with different technology performance expectations for 2020 were performed. The considered sites can contribute between 1 Mt/a and 1.8 Mt/a to the California Air Resources Board (CARB) goal of 6.7Mt/a CO2 abatement potential in 2020. Also, with lower PV and storage costs as well as consideration of a CO2 pricing scheme, our results indicate that PV and electric storage adoption can compete rather than supplement each other when the tariff structure and costs of electricity supply have been taken into consideration. To satisfy the site's objective of minimizing energy costs, the batteries will be charged also by CHP systems during off-peak and mid-peak hours and

    Urban Heat Island (UHI) which means urban air temperature is higher than suburban area is one of the most important environmental issues in Urban. High density of buildings and high ratio of impervious surfaces increases the radiation fluxes in urban canopy. Furthermore, climate change is expected to make UHI even more seriously in the future. Increased irradiation and air temperature cause high amount of short wave and long wave radiation, respectively. This increases net radiation negatively affects heat condition of pedestrian. UHI threatens citizen's health by increasing violence and heat related diseases. For this reason, understanding how much urban radiation will increase in the future, and exploring radiation reduction strategies is important for reducing UHI. In this research, we aim to reveal how the radiation flux in the urban canyon will change as the climate change and determine how much of urban vegetation will be needed to cover this degradation. The study area is a commercial district in Seoul where highly populated area. Due to the high density of buildings and lack of urban vegetation, this area has a poor thermal condition in summer. In this research, we simulate the radiation flux on the ground using multi-layer urban canopy model. Unlike conventionally used urban canopy model to simulate radiation transfer using vertically single layer, the multi-layer model we used here, enables to consider the vertical heterogeneous of buildings and urban vegetation. As a result, net radiation of urban ground will be increase 2.1 W/m² in the 2050s and 2.7 W/m² in the 2100s. And to prevent the increase of radiation, it is revealed that the urban vegetation should by increased by 10%. This research will be valuable in establishing greening planning as a strategy to reduce UHI effect.

  17. Delivering step change improvements to UK low level waste strategy - 16188

    Dean, Jason; Rossiter, David

    2009-01-01

    The UK Nuclear Industry continues to produce significant quantities of Low Level Waste (LLW) as decommissioning projects generating waste become more prevalent. Current infrastructure and projected increasing waste volumes will deliver a volumetric shortfall of storage capacity in the near future. Recently established as a standalone site licence company, the Low Level Waste Repository (LLWR) near Drigg, in West Cumbria (formerly operated and owned by British Nuclear Group) is tasked with managing the safe treatment and disposal of LLW in the UK, on behalf of the Nuclear Decommissioning Authority (NDA). The problem is complex involving many stakeholders with potentially different priorities. Previously, most nuclear waste generators operated independently with limited integration with other similar organisations. However, the current financial, programme and technical pressures require collaborative working to facilitate a step-change improvement in LLW management. Achieving this quickly is as much of a challenge as delivering robust cost effective technical solutions. NDA is working in partnership with LLWR to develop a LLW Strategy for the Nuclear Industry and has in parallel commissioned a number of studies by the National Nuclear Laboratory (NNL), looking at opportunities to share best practice. A National Strategy Group has been established to develop a working partnership between the Nuclear Decommissioning Authority, LLW Repository Ltd, Regulators, Stakeholders and LLW Consignors, promoting innovation, value for money, and robust implementation of the waste hierarchy (avoid-reduce-re-use-recycle). Additionally the LLWR supported by the NNL have undertaken a comprehensive strategic review of the UK's LLW management activities. Initial collaborative work has provided for the first time a detailed picture of the existing strategic baseline and identified significant national benefits from improving the way LLW is forecasted, characterised, segregated, and

    Even if we succeed in achieving the EU target of reducing global warming to 2 C, it will be absolutely essential to adapt to changing climatic conditions. The greenhouse gases currently present in the atmosphere will influence the climate in coming decades. The day on which it is quite clear which climatic scenario prevails, so that it is possible to model all relevant processes down to regional level, will be the day on which it is too late to adapt to the actual scenario. Our endeavours to adapt to climate change do not mean, however, that we can neglect to take measures in order to reduce the output of greenhouse gases. It is important to remember that on their own, neither adaptation nor mitigation can prevent the grave impacts resulting from climate change. In fact, they complement each other meaningfully thus helping to alleviate the risks of climate change. On 17th December 2008 the German Federal Cabinet adopted the DAS (German Strategy for the Adaptation to Climate Change), (Bundesregierung 2008). The DAS has created the framework for adapting to the consequences of climate change in Germany. First and fore-most, the DAS contributes its guidelines at Federal level, to provide a guideline for agents at other levels. The Strategy lays the foundation for a medium-term process. In conjunction with the individual Federal States and other groups representing various sectors of society, the Strategy provides a step-by-step assessment of the risks of climate change. Furthermore, it states the potential requirements for action, and defines the appropriate goals and potential adaptation measures to be developed and implemented in this process. In due course, the Federal Environment Agency (UBA) will design a comprehensive set of tools to support and advance the DAS. An integral part of this will be the Special Information System 'Adaptation' (FISKA) and an Indicator System to aid adaptation. The latter is one of the key tasks identified for the DAS. As far

  20. Reaping the carbon rent: Abatement and overallocation profits in the European cement industry, insights from an LMDI decomposition analysis

    Branger, Frédéric; Quirion, Philippe

    2015-01-01

    We analyse variations of carbon emissions in the European cement industry from 1990 to 2012, at the European level (EU 27), and at the national level for six major producers (Germany, France, Spain, the United Kingdom, Italy and Poland). We apply a Log-Mean Divisia Index (LMDI) method, cross-referencing data from three databases: the Getting the Numbers Right (GNR) database developed by the Cement Sustainability Initiative, the European Union Transaction Log (EUTL), and the Eurostat International Trade database. Our decomposition method allows seven channels of emission change to be distinguished: activity, clinker trade, clinker share, alternative fuels, thermal and electrical energy efficiency, and electricity decarbonisation. We find that, apart from a slow trend of emission reductions coming from technological improvements (first from a decrease in the clinker share, then from an increase in alternative fuels), most of the emission change can be attributed to the activity effect. Using counterfactual scenarios, we estimate that the introduction of the EU ETS brought small but positive technological abatement (2.2% ± 1.3% between 2005 and 2012). Moreover, we find that the European cement industry has gained 3.5 billion Euros of “overallocation profits”, mostly due to the slowdown of production. - Highlights: • We analyse variations of carbon emissions in the European cement industry. • We apply a Log-Mean Divisia Index (LMDI) method. • Most of the emission changes can be attributed to the activity effect. • The EU ETS brought small but positive technological abatement. • The European cement industry has gained 3.5 billion Euros of “overallocation profits”

  1. The politics of indigeneity: Indigenous strategies for inclusion in climate change negotiations

    Doolittle Amity

    2010-01-01

    Full Text Available Indigenous environmental activists have clearly articulated their views on global climate change policy. The content of these views was explored during the 10-day 2008 World Conservation Congress (WCC in Barcelona. Data were primarily collected through interviews and participant observation. In addition, policy statements and declarations made by indigenous environmental activists from 2000 to 2009 were analysed to place the perspectives of indigenous leaders and environmental activists in the context of their decade-long struggle to gain negotiating power at the United Nations Framework Convention on Climate Change. This study examines the rhetorical strategies indigenous leaders from around the world use to gain political recognition and legitimacy in climate change negotiations. Two core principles, relating to a particular representation of indigenous environmental knowledge are identified as fundamental rhetorical tools. These are a belief that the earth is a living being with rights and the conviction that it is the responsibility of indigenous peoples to protect the earth from over-exploitation. However, reference to indigenous environmental knowledge is not the only rhetorical mechanism used by indigenous leaders in the climate debates. When faced with specific United Nations policies to combat climate change that could have a profound impact on their land rights, some indigenous leaders adopt a more confrontational response. Fearing that new polices would reinforce historical trends of marginalisation, indigenous leaders seeking recognition in climate change debates speak less about their ecological knowledge and responsibility to the earth and more about their shared histories of political and economic marginalisation and land dispossession, experienced first through colonialism and more recently through globalisation.

    With established partnerships in higher education, K-12, and informal science education communities across Delaware and Maryland, the NSF-funded MADE CLEAR project (Maryland Delaware Climate Change Education, Assessment, and Research) has instituted a suite of professional development strategies to bring climate change science into science education methods courses, K-12 classrooms, university lecture halls, and public park facilities. MADE CLEAR partners have provided consistent climate literacy topics (mechanisms, human contributions, local and global impacts, mitigation and adaptation) while meeting the unique needs of each professional community. In-person topical lectures, hands-on work with classroom materials, seed funding for development of new education kits, and on-line live and recorded sessions are some of the tools employed by the team to meet those needs and build enduring capacity for climate change science education. The scope of expertise of the MADE CLEAR team, with climate scientists, educators, learning scientists, and managers has provided not only PD tailored for each education audience, but has also created, fostered, and strengthened relationships across those audiences for long-term sustainability of the newly-built capacity. Specific examples include new climate change programs planned for implementation across Delaware State Parks that will be consistent with middle school curriculum; integration of climate change topics into science methods classes for pre-service teachers at four universities; and active K-12 and informal science education teams working to cooperatively develop lessons that apply informal science education techniques and formal education pedagogy. Evaluations by participants highlight the utility of personal connections, access to experts, mentoring and models for developing implementation plans.

  3. The diversity of gendered adaptation strategies to climate change of Indian farmers: A feminist intersectional approach.

    Ravera, Federica; Martín-López, Berta; Pascual, Unai; Drucker, Adam

    2016-12-01

    This paper examines climate change adaptation and gender issues through an application of a feminist intersectional approach. This approach permits the identification of diverse adaptation responses arising from the existence of multiple and fragmented dimensions of identity (including gender) that intersect with power relations to shape situation-specific interactions between farmers and ecosystems. Based on results from contrasting research cases in Bihar and Uttarakhand, India, this paper demonstrates, inter alia, that there are geographically determined gendered preferences and adoption strategies regarding adaptation options and that these are influenced by the socio-ecological context and institutional dynamics. Intersecting identities, such as caste, wealth, age and gender, influence decisions and reveal power dynamics and negotiation within the household and the community, as well as barriers to adaptation among groups. Overall, the findings suggest that a feminist intersectional approach does appear to be useful and worth further exploration in the context of climate change adaptation. In particular, future research could benefit from more emphasis on a nuanced analysis of the intra-gender differences that shape adaptive capacity to climate change.

    1995-12-31

    The CERES-rice (Oryza sativa L.) model was calibrated and validated for nine sites in southern China to examine its suitability to model rice production in this area, using agronomic data from more than three successive years. After determining the genetic coefficients for the cultivars, the CERES-rice model was run a second time for the same locations for a time period of 20 to 30 yr. The model used local climate data (1958--1986) and doubled-CO{sub 2} climate change scenarios generated from the Goddard Institute for Space Studies (GISS), Geophysical Fluid dynamics Laboratory (GFDL), and United Kingdom Meteorological Office (UKMO) global climate models (GCMs), with and without supplemental irrigation(to model paddy and upland rice, respectively). The study estimated the potential impacts of climate change on rice production by comparing the base runs with the runs under the three doubled-CO{sub 2} GCM scenarios and it considered the physiological effects of CO{sub 2} on rice growth in each GCM scenario. Finally, the study examined several strategies for adapting to climate change.

  5. Changes in cigarette expenditure minimising strategies before and after a cigarette tax increase.

    Choi, Kelvin; Boyle, Raymond G

    2018-01-01

    Smokers use cigarette expenditure minimising strategies (CEMS) to alleviate the effect of tax increases on their cigarette expenses. We examined changes in smokers' CEMS use before and after a 2013 Minnesota $1.75 cigarette tax increase. Data were from representative samples of smokers who participated in the Minnesota Adult Tobacco Survey 2010 (n=948) and 2014 (n=1229). Participants indicated CEMS used in the past year from a list. Weighted multiple logistic regressions were used to examine changes in prevalence of each CEMS use over time adjusting for demographics and cigarette consumption. Characteristics associated with CEMS use in 2014 were examined. Between 2010 and 2014, more smokers tried to save money on cigarettes by rolling their own cigarettes (from 19% to 29%), using other tobacco products (from 13% to 25%), and buying cigarettes from cheaper places (from 48% to 55%). Yet, fewer smokers used coupons/promotions (from 63% to 50%) and bought cigarettes by the carton (from 39% to 32%). These changes varied somewhat by race/ethnicity and education, for example, more smokers with tax increase. Regulations that would reduce CEMS use could boost the effectiveness of cigarette tax increases. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    The revised Biological Monitoring and Abatement Program (BMAP) for East Fork Poplar Creek (EFPC) at the Oak Ridge Y-12 Plant, as described, will be conducted as required by the National Pollutant Discharge Elimination System permit issued for the Y-12 Plant on April 28, 1995 and became effective July 1, 1995. The basic approach to biological monitoring used in this program was developed by the staff in the Environmental Science Division (ESD) at the Oak Ridge National Laboratory (ORNL) at the request of the Y-12 Plant. The revision to the BMAP plan is based on results of biological monitoring conducted during the period of 1985 to present. Details of the specific procedures used in the current routine monitoring program are provided; experimental designs for future studies are described in less detail. The overall strategy used in developing this plan was, and continues to be, to use the results obtained from each task to define the scope of future monitoring efforts. Such efforts may require more intensive sampling than initially proposed in some areas (e.g., additional bioaccumulation monitoring if results indicate unexpectedly high PCBs or Hg) or a reduction in sampling intensity in others (e.g., reduction in the number of sampling sites when no impact is still observed). The program scope will be re-evaluated annually. By using the results of previous monitoring efforts to define the current program and to guide us in the development of future studies, an effective integrated monitoring program has been developed to assess the impacts of Y-12 Plant operations (past and present) on the biota of EFPC and to document the ecological effects of remedial actions.

  7. Managing Risk Aversion for Low-Carbon Supply Chains with Emission Abatement Outsourcing.

    Wang, Qinpeng; He, Longfei

    2018-02-21

    Reducing carbon emissions, including emission abatement outsourcing at the supply-chain level, is becoming a significant but challenging problem in practice. Confronting this challenge, we therefore break down the practice to focus on a low-carbon supply chain consisting of one supplier, one manufacturer and one third-party emission-reducing contractor. The contractor offers a carbon reduction service to the manufacturer. In view of the increasing proportion of Greenhouse Gases (GHG) emissions and absence of carbon reduction policies in developing countries, we adopt the prospect of consumers' low-carbon preferences to capture the demand sensitivity on carbon emission. By exploiting the Mean-Variance (MV) model, we develop a supply chain game model considering risk aversion. Comparing the supply chain performances of the cases under risk neutrality and risk aversion, we investigate the impact of the risk aversion of the supplier and the manufacturer on the low-carbon supply chain performances, respectively. We show that the risk aversion of chain members will not influence the relationship underlain by the profit-sharing contract between the manufacturer and contractor, whereas they may extend the supplier's concerning range. Although the manufacturer's risk aversion has a positive impact on the wholesale price, interestingly, the supplier's impact on the wholesale price is negative. Furthermore, we propose a contract to coordinate the risk-averse low-carbon supply chain by tuning the aversion levels of the supplier and the manufacturer, respectively. Through numerical study, we draw on managerial insights for industrial practitioners to adopt a low carbon strategy potentially by managing the risk attitudes along the supply chain channel.

  11. Climate change implications of shifting forest management strategy in a boreal forest ecosystem of Norway.

    2014-02-01

    Empirical models alongside remotely sensed and station measured meteorological observations are employed to investigate both the local and global direct climate change impacts of alternative forest management strategies within a boreal ecosystem of eastern Norway. Stand-level analysis is firstly executed to attribute differences in daily, seasonal, and annual mean surface temperatures to differences in surface intrinsic biophysical properties across conifer, deciduous, and clear-cut sites. Relative to a conifer site, a slight local cooling of −0.13 °C at a deciduous site and −0.25 °C at a clear-cut site were observed over a 6-year period, which were mostly attributed to a higher albedo throughout the year. When monthly mean albedo trajectories over the entire managed forest landscape were taken into consideration, we found that strategies promoting natural regeneration of coniferous sites with native deciduous species led to substantial global direct climate cooling benefits relative to those maintaining current silviculture regimes – despite predicted long-term regional warming feedbacks and a reduced albedo in spring and autumn months. The magnitude and duration of the cooling benefit depended largely on whether management strategies jointly promoted an enhanced material supply over business-as-usual levels. Expressed in terms of an equivalent CO2 emission pulse at the start of the simulation, the net climate response at the end of the 21st century spanned −8 to −159 Tg-CO2-eq., depending on whether near-term harvest levels increased or followed current trends, respectively. This magnitude equates to approximately −20 to −300% of Norway's annual domestic (production) emission impact. Our analysis supports the assertion that a carbon-only focus in the design and implementation of forest management policy in boreal and other climatically similar regions can be counterproductive – and at best – suboptimal if boreal forests are to be used as a

  12. Energy efficiency as a greenhouse gas mitigation strategy

    Salmon, G.

    1995-01-01

    This paper focuses on the best strategy for New Zealand to follow in order to meet obligations under the Framework Convention on Climate Change (FCCC). The New Zealand government's current policy is to rely on the increased carbon storage in commercial tree plantings to meet 80% of FCCC obligations with the balance being met by policy measures including voluntary energy efficiency agreements with industry and enhanced state support for energy efficiency activities. If targets are not on track for achievement by 2000, the government will introduce a carbon charge in 1997. An alternative strategy involving microeconomic reforms in the electricity and transport sectors and tradable abatement obligations including credits for emission reductions and carbon storage is proposed. 1 fig., 11 refs

  13. Does investment in leaf defenses drive changes in leaf economic strategy? A focus on whole-plant ontogeny.

    Mason, Chase M; Donovan, Lisa A

    2015-04-01

    Leaf defenses have long been studied in the context of plant growth rate, resource availability, and optimal investment theory. Likewise, one of the central modern paradigms of plant ecophysiology, the leaf economics spectrum (LES), has been extensively studied in the context of these factors across ecological scales ranging from global species data sets to temporal shifts within individuals. Despite strong physiological links between LES strategy and leaf defenses in structure, function, and resource investment, the relationship between these trait classes has not been well explored. This study investigates the relationship between leaf defenses and LES strategy across whole-plant ontogeny in three diverse Helianthus species known to exhibit dramatic ontogenetic shifts in LES strategy, focusing primarily on physical and quantitative chemical defenses. Plants were grown under controlled environmental conditions and sampled for LES and defense traits at four ontogenetic stages. Defenses were found to shift strongly with ontogeny, and to correlate strongly with LES strategy. More advanced ontogenetic stages with more conservative LES strategy leaves had higher tannin activity and toughness in all species, and higher leaf dry matter content in two of three species. Modeling results in two species support the conclusion that changes in defenses drive changes in LES strategy through ontogeny, and in one species that changes in defenses and LES strategy are likely independently driven by ontogeny. Results of this study support the hypothesis that leaf-level allocation to defenses might be an important determinant of leaf economic traits, where high investment in defenses drives a conservative LES strategy.

  14. Benefits from restoring wetlands for nitrogen abatement: A case study of Gotland

    Gren, I.M.

    1992-01-01

    The values of nitrogen abatement by measures involving restoration of wetlands, sewage treatment plants and agriculture are calculated and compared. The analytical results show that the value of wetlands is likely to exceed the values of other measures due to the multi-functionality of wetlands and their self-organizing ability. The multi-functionality implies that, in addition to nitrogen abatement, other outputs like buffering of water and biodiversity are produced and the self-organizing feature reduces the rate at which future values of outputs are discounted. According to the empirical results applied to Gotland, a Swedish island in the Baltic with high concentrations of nitrate in the ground water, the imputed value of wetlands exceeds the corresponding values of the other nitrogen abatement measures by several hundred per cent. 21 refs, 6 tabs

    Translating behavioral theories, models, and strategies to guide the development and structure of computer-based health applications is well recognized, although a continued challenge for program developers. A stepped approach to translate behavioral theory in the design of simulations to teach chronic disease management to children is described. This includes the translation steps to: 1) define target behaviors and their determinants, 2) identify theoretical methods to optimize behavioral change, and 3) choose educational strategies to effectively apply these methods and combine these into a cohesive computer-based simulation for health education. Asthma is used to exemplify a chronic health management problem and a computer-based asthma management simulation (Watch, Discover, Think and Act) that has been evaluated and shown to effect asthma self-management in children is used to exemplify the application of theory to practice. Impact and outcome evaluation studies have indicated the effectiveness of these steps in providing increased rigor and accountability, suggesting their utility for educators and developers seeking to apply simulations to enhance self-management behaviors in patients.

  16. Rational choice and the political bases of changing Israeli counterinsurgency strategy.

    Brym, Robert J; Andersen, Robert

    2011-09-01

    Israeli counterinsurgency doctrine holds that the persistent use of credible threat and disproportionate military force results in repeated victories that eventually teach the enemy the futility of aggression. The doctrine thus endorses classical rational choice theory's claim that narrow cost-benefit calculations shape fixed action rationales. This paper assesses whether Israel's strategic practice reflects its counterinsurgency doctrine by exploring the historical record and the association between Israeli and Palestinian deaths due to low-intensity warfare. In contrast to the expectations of classical rational choice theory, the evidence suggests that institutional, cultural and historical forces routinely override simple cost-benefit calculations. Changing domestic and international circumstances periodically cause revisions in counterinsurgency strategy. Credible threat and disproportionate military force lack the predicted long-term effect. © London School of Economics and Political Science 2011.

    2014-04-01

    National immunization programs in developing countries have made major strides to immunize the world's children, increasing full coverage to 83% of children. However, the World Health Organization estimates that 22 million children less than five years of age are left unvaccinated, and coverage levels have been plateauing for nearly a decade. This paper describes the evidence on factors contributing to low vaccination uptake, and describes the connection between these factors and the documented strategies and interventions that can lead to changes in immunization outcomes. The author suggests that investments in these areas may contribute more effectively to immunization coverage and also have positive spill-over benefits for health systems. The paper concludes that while some good quality evidence exists of what works and may contribute to immunization outcomes, the quality of evidence needs to improve and major gaps need to be addressed.

    Tripping over an obstacle is one of the most common causes of falls among older adults. However, the effects of aging, obstacle height and anticipation time on negotiation strategies have not been systematically evaluated. Twenty older adults (ages: 77.7±3.4years; 50% women) and twenty young adults (age: 29.3±3.8years; 50% women) walked through an obstacle course while negotiating anticipated and unanticipated obstacles at heights of 25mm and 75mm. Kinect cameras captured the: (1) distance of the subject's trailing foot before the obstacles, (2) distance of the leading foot after the obstacles, (3) clearance of the leading foot above the obstacles, and (4) clearance of the trailing foot above the obstacles. Linear-mix models assessed changes between groups and conditions. Older adults placed their leading foot closer to the obstacle after landing, compared to young adults (p<0.001). This pattern was enhanced in high obstacles (group*height interaction, p=0.033). Older adults had lower clearance over the obstacles, compared to young adults (p=0.007). This was more pronounced during unanticipated obstacles (group*ART interaction, p=0.003). The distance of the leading foot and clearance of the trailing foot after the obstacles were correlated with motor, cognitive, and functional abilities. These findings suggest that there are age-related changes in obstacle crossing strategies that are dependent on the specific characteristics of the obstacle. The results have important implications for clinical practice, suggesting that functional exercise should include obstacle negotiation training with variable practice of height and available response times. Further studies are needed to better understand the effects of motor and cognitive abilities. Copyright © 2017 Elsevier B.V. All rights reserved.

  19. A structural equation model to integrate changes in functional strategies during old-field succession.

    Vile, Denis; Shipley, Bill; Garnier, Eric

    2006-02-01

    From a functional perspective, changes in abundance, and ultimately species replacement, during succession are a consequence of integrated suites of traits conferring different relative ecological advantages as the environment changes over time. Here we use structural equations to model the interspecific relationships between these integrated functional traits using 34 herbaceous species from a Mediterranean old-field succession and thus quantify the notion of a plant strategy. We measured plant traits related to plant vegetative and reproductive size, leaf functioning, reproductive phenology, seed mass, and production on 15 individuals per species monitored during one growing season. The resulting structural equation model successfully accounts for the pattern of trait covariation during the first 45 years post-abandonment using just two forcing variables: time since site abandonment and seed mass; no association between time since field abandonment and seed mass was observed over these herbaceous stages of secondary succession. All other predicted traits values are determined by these two variables and the cause-effect linkage between them. Adding pre-reproductive vegetative mass as a third forcing variable noticeably increased the predictive power of the model. Increasing the time after abandonment favors species with increasing life span and pre-reproductive biomass and decreasing specific leaf area. Allometric coefficients relating vegetative and reproductive components of plant size were in accordance with allometry theory. The model confirmed the trade-off between seed mass and seed number. Maximum plant height and seed mass were major determinants of reproductive phenology. Our results show that beyond verbal conceptualization, plant ecological strategies can be quantified and modeled.

  1. Carbon dioxide abatement in an empirical model of the Indian economy: an integration of micro and macro analysis

    Gupta, S.

    1995-01-01

    Global warming and associated climate change are the likely results of an enhanced greenhouse effect due to excessive emission of greenhouse gases. Carbon dioxide (CO 2 ) is the largest contributor to the greenhouse effect. The costs of stabilising or reducing CO 2 emissions are estimated by two types of models. Macro models based on aggregate macroeconomic relationships, study the macroeconomic impacts of and responses to different policies. These overestimate costs as technological responses are not adequately modelled. Micro models contain the necessary technical information to assess the abatement potential, but exclude indirect costs. In this study, a methodology for integrating the two approaches for developing countries is proposed and illustrated for India. The problems associated with modelling developing economies are recognized in the integrated model proposed. (Author)

    Vandenbroucke, Arne; Aerts, Robby; Morent, Rino; De Geyter, Nathalie; Bogaerts, Annemie; Leys, Christophe

    2012-01-01

    In this study, the formation of ozone and the abatement of trichloroethylene (TCE) with non thermal plasma was experimentally and theoretically investigated. The model predicts that the ozone formation increases with the energy deposition and decreases with the relative humidity (RH) of the air, which is qualitatively in agreement with experimental data. For an energy deposition of 0.136 J/cm³, the abatement of 1000 ppm TCE in air with 5 % RH is dominated by atomic oxygen and to a lesser exte...

  3. Evaluation of co-benefits from combined climate change and air pollution reduction strategies

    Leitao, Joana; Van Dingenen, Rita; Dentener, Frank; Rao, Shilpa

    2014-05-01

    The connection of climate change and air pollution is becoming more relevant in the process of policy making and implementation of emission control strategies because of resulting co-benefits and trade-offs. Some sectors, such as fossil fuel combustion, are sources of both pollutants (NOx and PM) as well as greenhouse gas (CO2). Additionally, the use of wood burning as biofuel to reduce climate impact may in fact deteriorate air quality. Furthermore, several air pollutants are important radiative forcers and regulating their emissions impacts on climate. It is evident that both problems need to be undertaken with a common strategy and the existence of cross-policy with co-benefits may encourage their implementation. The LIMITS FP7 project (http://www.feem-project.net/limits/index.html) was designed with the main goal of assessing strategies for reduction of GHG emissions so that the 2°C target can be achieved. The work developed focus on the evaluation of the implementation of strategies analysing several aspects of different scenarios, namely: the feasibility of low carbon scenarios in terms of available technologies and infrastructure, the required financial mechanisms, and also the co-benefits regarding energy security, economic development and air pollution. For the latter, five integrated assessment models (IAMs) provided greenhouse gases and pollutant emission values for several scenarios. These were based on air pollution scenarios defined according to stringency and implementation of future global legislation. They which were also combined with 2 climate policy scenarios (no climate policy and 2.8 W/m2 target). The former are mostly focused on non-climate policies and technical control measures for emissions of air pollutants, such as PM2.5, NOx and SO2, with their emission factors harmonized between the IAMs. With the global air quality source-receptor model TM5-FASST the impact of the resulting emissions was analysed and the co-benefits of combined

  5. Object-Based Change Detection in Urban Areas: The Effects of Segmentation Strategy, Scale, and Feature Space on Unsupervised Methods

    Lei Ma

    2016-09-01

    Full Text Available Object-based change detection (OBCD has recently been receiving increasing attention as a result of rapid improvements in the resolution of remote sensing data. However, some OBCD issues relating to the segmentation of high-resolution images remain to be explored. For example, segmentation units derived using different segmentation strategies, segmentation scales, feature space, and change detection methods have rarely been assessed. In this study, we have tested four common unsupervised change detection methods using different segmentation strategies and a series of segmentation scale parameters on two WorldView-2 images of urban areas. We have also evaluated the effect of adding extra textural and Normalized Difference Vegetation Index (NDVI information instead of using only spectral information. Our results indicated that change detection methods performed better at a medium scale than at a fine scale where close to the pixel size. Multivariate Alteration Detection (MAD always outperformed the other methods tested, at the same confidence level. The overall accuracy appeared to benefit from using a two-date segmentation strategy rather than single-date segmentation. Adding textural and NDVI information appeared to reduce detection accuracy, but the magnitude of this reduction was not consistent across the different unsupervised methods and segmentation strategies. We conclude that a two-date segmentation strategy is useful for change detection in high-resolution imagery, but that the optimization of thresholds is critical for unsupervised change detection methods. Advanced methods need be explored that can take advantage of additional textural or other parameters.

  8. A climate for development. Climate change policy options for Africa

    Okoth-Ogendo, H.W.O.; Ojwang, J.B.

    1995-01-01

    The seriousness of the potential impacts of climate change on development in Africa is now well recognized within, and increasingly outside, scientific circles. The United Nations Framework Convention on Climate Change is a landmark in international environmental governance, providing a mechanism for exchange, negotiation and institution-building to re-direct development towards more efficient use of resources, especially energy. The message of 'A climate for Development' is that unless policy-makers fully understand both the international commitments made under the Convention and the essential national development priorities of their own countries, effective action on climate change is unlikely to be realized. The action needed, however, can at the same time stimulate capacity-building, planning and policy change which would strengthen the economic and ecological base of African countries. The climate change issue has hence brought us face to face with the urgency of the basic issues of sustainable development in Africa. The book discusses key issues that cut across all African countries, such as emissions and their impacts, financial resources and technology transfer for emissions abatement strategies. It then provides a sectoral analysis of greenhouse gas emissions and abatement options focusing on energy, industry, agriculture, forestry and transportation. The book concludes with guidelines for options which may be considered by African countries to ensure that climate change concerns are effectively dealt with in the context of their development priorities. 113 refs

  9. Changes in Student Perceptions and Study Strategies Over Time in a Veterinary Clinical Pathology Course Using Case-Based Instruction.

    Fernandez, Nicole J; Wagg, Catherine R; Warren, Amy L

    2018-06-13

    Veterinary students are challenged to develop new, nonlinear ways of thinking as they learn diagnostic reasoning skills. To support this process, we use real-life cases in our clinical pathology course. Changes in student perceptions regarding the use of cases and changes in study strategies over time have not been previously investigated or compared to student grades. Students participated in three voluntary online surveys that included 4-point Likert scale questions and open-ended questions on the helpfulness of cases for learning and study strategies used during the course. We used Friedman tests to detect any differences in perceptions over time; McNemar's test and "Wilcoxon signed-rank tests were used to detect any differences in study strategies over time. Fisher's exact tests'were used to examine the association between the Likert scale responses and grades in quartiles. Before beginning the course, 29% of students responded that cases were very helpful to their learning, with similar "responses for helpfulness in applying course material and grasping important concepts. There was a significant trend of increasing positivity over the duration of the course, with 74% responding that cases were very helpful at the end of the course. The most-reported study strategy was working individually on cases before the midterm (74% of students), and the most helpful study strategy was attending class regularly (88% reported it as very "helpful). Study strategies did not change significantly over time. Overall, perceptions and study strategies did not vary significantly with grades.

  10. Novice medical students: individual patterns in the use of learning strategies and how they change during the first academic year.

    Fabry, Götz; Giesler, Marianne

    2012-01-01

    Adequate use of different learning strategies is one of the most important prerequisites of academic success. The actual use of learning strategies is the result of an interaction between individual and situational variables. Against this background we conducted a longitudinal study with first year medical students to investigate whether individuals show different patterns in their use of learning strategies and whether these patterns change during the first academic year. Medical students (N=175, 58% female) were surveyed three times in their first academic year regarding their use of learning strategies. A hierarchical cluster analysis (Ward) was conducted in order to identify groups of students with different patterns of learning strategies. We identified four different patterns in approaches to learning among novice medical students ("easy-going", "flexible", "problematic" and "hardworking" learners). Compared to their peers, the problematic learners had the worst final school grades. In addition changes in the use of learning strategies were identified, most of them occurred during the first term. Students start their academic studies with different patterns of learning strategies; the characteristics of these patterns change during the first academic year. Further research is necessary to better understand how individual and situational variables determine students' learning.

  11. Enabling long-term oceanographic research: Changing data practices, information management strategies and informatics

    Baker, Karen S.; Chandler, Cynthia L.

    2008-09-01

    Interdisciplinary global ocean science requires new ways of thinking about data and data management. With new data policies and growing technological capabilities, datasets of increasing variety and complexity are being made available digitally and data management is coming to be recognized as an integral part of scientific research. To meet the changing expectations of scientists collecting data and of data reuse by others, collaborative strategies involving diverse teams of information professionals are developing. These changes are stimulating the growth of information infrastructures that support multi-scale sampling, data repositories, and data integration. Two examples of oceanographic projects incorporating data management in partnership with science programs are discussed: the Palmer Station Long-Term Ecological Research program (Palmer LTER) and the United States Joint Global Ocean Flux Study (US JGOFS). Lessons learned from a decade of data management within these communities provide an experience base from which to develop information management strategies—short-term and long-term. Ocean Informatics provides one example of a conceptual framework for managing the complexities inherent to sharing oceanographic data. Elements are introduced that address the economies-of-scale and the complexities-of-scale pertinent to a broader vision of information management and scientific research.

    Although changes in brain function induced by cognitive training have been examined, functional plasticity associated with specific training strategies is still relatively unexplored. In this study, we examined changes in brain function during a complex visuomotor task following training using the Space Fortress video game. To assess brain function, participants completed functional magnetic resonance imaging (fMRI) before and after 30 h of training with one of two training regimens: Hybrid Variable-Priority Training (HVT), with a focus on improving specific skills and managing task priority, or Full Emphasis Training (FET), in which participants simply practiced the game to obtain the highest overall score. Control participants received only 6 h of FET. Compared to FET, HVT learners reached higher performance on the game and showed less brain activation in areas related to visuo-spatial attention and goal-directed movement after training. Compared to the control group, HVT exhibited less brain activation in right dorsolateral prefrontal cortex (DLPFC), coupled with greater performance improvement. Region-of-interest analysis revealed that the reduction in brain activation was correlated with improved performance on the task. This study sheds light on the neurobiological mechanisms of improved learning from directed training (HVT) over non-directed training (FET), which is related to visuo-spatial attention and goal-directed motor planning, while separating the practice-based benefit, which is related to executive control and rule management.

  13. Will Transition of Staple Food Strategy in China Really Mitigate Global Climate Change?

    Liu, B.; Zhao, D.

    2017-12-01

    With the increase in agricultural demand, reducing greenhouse gas (GHG) emissions is a vital challenge in mitigating climate change. Potato staple food strategy in China introduced by Ministry of Agriculture in 2015 is to gradually adjust staple food structure, which provides an opportunity to meet with the challenge. Apart from staple food structure, difference on energy, material input, geography, and crop management are essential to determine agriculture's contribution to climate change. In this study, we conduct a life cycle analysis of four staple foods in China, namely rice, wheat, maize, and potato, to develop crop-specific estimates of GHG emissions and GHG intensity by using `Production intensity' (carbon dioxide equivalent emissions per kilocalorie produced), to help us understand potential synergies and frictions between food producing and climate mitigation. Data used in this study is on city / province levels if city level is unavailable in 2015. First, we evaluate GHG reductions due to transition of staple food structure in China. Staple food GHG emissions in China are 546.90 Tg CO2e yr-1 in 2015, with 47.6%, 21.9%, 27.3% and 3.2% from rice, wheat, maize and potato. Mean production intensity of staple food is 0.45 Mg CO2e M kcal-1 in 2015. Maize leads the intensity with 0.77 Mg CO2e M kcal-1, followed by rice (0.49 Mg CO2e M kcal-1), wheat (0.28 Mg CO2e M kcal-1) and potato (0.24 Mg CO2e M kcal-1). After staple food structure adjustment, 25 Tg CO2e yr-1 (4.2%) reduction will be accomplished in 2020 without any crop management improvement. Further reduction (33.3% - 40.4%) could be achieved with crop management improvement. In addition, because of staple food structure switching, native rice production will decline, which might lead to more export from countries with higher production intensity. Estimated emission leakage from rice import is 30.10 Tg CO2e yr-1, exceeds emission reduction in native China. Therefore, potato staple food strategy could

  14. Ancient cellular structures and modern humans: change of survival strategies before prolonged low solar activity period

    Ragulskaya, Mariya; Rudenchik, Evgeniy; Gromozova, Elena; Voychuk, Sergei; Kachur, Tatiana

    The study of biotropic effects of modern space weather carries the information about the rhythms and features of adaptation of early biological systems to the outer space influence. The influence of cosmic rays, ultraviolet waves and geomagnetic field on early life has its signs in modern biosphere processes. These phenomena could be experimentally studied on present-day biological objects. Particularly inorganic polyphosphates, so-called "fossil molecules", attracts special attention as the most ancient molecules which arose in inanimate nature and have been accompanying biological objects at all stages of evolution. Polyphosphates-containing graves of yeast's cells of Saccharomyces cerevisiae strain Y-517, , from the Ukrainian Collection of Microorganisms was studied by daily measurements during 2000-2013 years. The IZMIRAN daily data base of physiological parameters dynamics during 2000-2013 years were analyzed simultaneously (25 people). The analysis showed significant simultaneous changes of the statistical parameters of the studied biological systems in 2004 -2006. The similarity of simultaneous changes of adaptation strategies of human organism and the cell structures of Saccharomyces cerevisiae during the 23-24 cycles of solar activity are discussed. This phenomenon could be due to a replacement of bio-effective parameters of space weather during the change from 23rd to 24th solar activity cycle and nonstandard geophysical peculiarities of the 24th solar activity cycle. It could be suggested that the observed similarity arose as the optimization of evolution selection of the living systems in expectation of probable prolonged period of low solar activity (4-6 cycles of solar activity).

  15. FTO genotype, dietary protein, and change in appetite: the Preventing Overweight Using Novel Dietary Strategies trial.

    2014-05-01

    A common obesity-risk variant rs9939609 in the fat mass- and obesity-associated (FTO) gene was recently shown to affect appetite, and the gene is sensitive to the regulation of amino acids. We examined the interaction between FTO genotype and protein intake on the long-term changes in appetite in a randomized controlled trial. We genotyped FTO rs9939609 in 737 overweight adults in the 2-y Preventing Overweight Using Novel Dietary Strategies trial and assessed 4 appetite-related traits including cravings, fullness, hunger, and prospective consumption. We showed that dietary protein significantly modified genetic effects on changes in food cravings and appetite scores at 6 mo after adjustment for age, sex, ethnicity, baseline body mass index, weight change, and baseline value for respective outcomes (P-interaction = 0.027 and 0.048, respectively). The A allele was associated with a greater decrease in food cravings and appetite scores in participants with high-protein-diet intake (P = 0.027 and 0.047, respectively) but not in subjects in the low-protein-diet group (P = 0.384 and 0.078, respectively). The weight regain from 6 to 24 mo attenuated gene-protein interactions. Protein intakes did not modify FTO genotype effects on other appetite measures. Our data suggest that individuals with the FTO rs9939609 A allele might obtain more benefits in a reduction of food cravings and appetite by choosing a hypocaloric and higher-protein weight-loss diet. This trial was registered at clinicaltrials.gov as NCT00072995.

  16. Drivers of change in hunter offtake and hunting strategies in Sendje, Equatorial Guinea.

    2012-12-01

    Economic development in Africa is expected to increase levels of bushmeat hunting through rising demand for meat and improved transport infrastructure. However, few studies have tracked long-term changes in hunter behavior as a means of testing this prediction. We evaluated changes in hunter behavior in a rural community in Equatorial Guinea over a period of rapid national economic growth, during which time road access to the regional capital greatly improved. We conducted offtake surveys (Supporting Information) over 3 7-week periods at the same time of year in 1998, 2003, and 2010 and conducted hunter and household interviews (Supporting Information) in 2003 and 2010. We tested whether relations existed among catch, hunting effort, hunting strategy, and income earned through hunting and other livelihoods in 2003 and 2010. Although village offtake increased from 1775 kg in 1998 to 4172 kg in 2003, it decreased in 2010 to 1361 kg. Aggregate catch per unit effort (i.e., number of carcasses caught per hunter and per trap) decreased from 2003 to 2010, and the majority of hunters reported a decrease in abundance of local fauna. Although these results are indicative of unsustainable hunting, cumulative changes in offtake and catch per unit effort were driven by a contraction in the total area hunted following an out-migration of 29 of the village's hunters, most of whom left to gain employment in the construction industry, after 2003. Hunters operating in both 2003 and 2010 hunted closer to the village because an increased abundance of elephants posed a danger and because they desired to earn income through other activities. Our study provides an example of national economic development contributing to a reduction in the intensity and extent of hunting. ©2012 Society for Conservation Biology.

    2018-04-03

    Strategies to mitigate carbon dioxide emissions through forestry activities have been proposed, but ecosystem process-based integration of climate change, enhanced CO 2 , disturbance from fire, and management actions at regional scales are extremely limited. Here, we examine the relative merits of afforestation, reforestation, management changes, and harvest residue bioenergy use in the Pacific Northwest. This region represents some of the highest carbon density forests in the world, which can store carbon in trees for 800 y or more. Oregon's net ecosystem carbon balance (NECB) was equivalent to 72% of total emissions in 2011-2015. By 2100, simulations show increased net carbon uptake with little change in wildfires. Reforestation, afforestation, lengthened harvest cycles on private lands, and restricting harvest on public lands increase NECB 56% by 2100, with the latter two actions contributing the most. Resultant cobenefits included water availability and biodiversity, primarily from increased forest area, age, and species diversity. Converting 127,000 ha of irrigated grass crops to native forests could decrease irrigation demand by 233 billion m 3 ⋅y -1 Utilizing harvest residues for bioenergy production instead of leaving them in forests to decompose increased emissions in the short-term (50 y), reducing mitigation effectiveness. Increasing forest carbon on public lands reduced emissions compared with storage in wood products because the residence time is more than twice that of wood products. Hence, temperate forests with high carbon densities and lower vulnerability to mortality have substantial potential for reducing forest sector emissions. Our analysis framework provides a template for assessments in other temperate regions. Copyright © 2018 the Author(s). Published by PNAS.

  19. Tobacco litter costs and public policy: a framework and methodology for considering the use of fees to offset abatement costs.

    Schneider, John E; Peterson, N Andrew; Kiss, Noemi; Ebeid, Omar; Doyle, Alexis S

    2011-05-01

    Growing concern over the costs, environmental impact and safety of tobacco product litter (TPL) has prompted states and cities to undertake a variety of policy initiatives, of which litter abatement fees are part. The present work describes a framework and methodology for calculating TPL costs and abatement fees. Abatement is associated with four categories of costs: (1) mechanical and manual abatement from streets, sidewalks and public places, (2) mechanical and manual abatement from storm water and sewer treatment systems, (3) the costs associated with harm to the ecosystem and harm to industries dependent on clean and healthy ecosystems, and (4) the costs associated with direct harm to human health. The experiences of the City of San Francisco's recently proposed tobacco litter abatement fee serve as a case study. City and municipal TPL costs are incurred through manual and mechanical clean-up of surfaces and catchment areas. According to some studies, public litter abatement costs to US cities range from US$3 million to US$16 million. TPL typically comprises between 22% and 36% of all visible litter, implying that total public TPL direct abatement costs range from about US$0.5 million to US$6 million for a city the size of San Francisco. The costs of mitigating the negative externalities of TPL in a city the size of San Francisco can be offset by implementing a fee of approximately US$0.20 per pack. Tobacco litter abatement costs to cities can be substantial, even when the costs of potential environmental pollution and tourism effects are excluded. One public policy option to address tobacco litter is levying of fees on cigarettes sold. The methodology described here for calculating TPL costs and abatement fees may be useful to state and local authorities who are considering adoption of this policy initiative.

  20. Out of the Crisis. A radical change of strategy for the Eurozone

    Andrea Ginzburg

    2017-06-01

    Full Text Available The paper argues that the crisis, mistakenly interpreted as a standard fiscal/balance of payments problem, was generated by the incomplete nature of the European institutions and a disregard for the consequences of differences in the stages of development of the member countries. The ideological pre-conception that markets are self-equilibrating through price competition has been used to justify disastrous internal devaluation policies in the belief that an austerity regime associated with institutions close to those assumed to prevail in 'core' countries would create the 'right' environment for resuming growth in the periphery. An analysis of the main phases of the development of European countries since the second post-war period provides evidence of wide differences in the productive structures of the countries of the centre and the southern periphery of Europe at the start of the Europeanization process. These differences entailed an asymmetric capacity of countries at differing levels of development to adjust to external shocks. This longer-term perspective helps us better to assess the limitations of the two alternatives that have been suggested to steer the EZ economy out of its present quagmire: internal devaluation (wage flexibility in the deficit (Southern European countries, or expansion of internal demand in 'core' countries (Germany. Both measures, it is argued, do not go to the root of the development and debt sustainability problems of Southern European countries, which continue to lack a sufficiently broad and differentiated productive structure. Given the differences in the levels of development of the various EU countries and their varying capacities to cope with change, fiscal policy should be assigned two complementary targets: the role of actively promoting — through investment —the removal of development bottlenecks and the renewal of the productive base, and a redistributive and compensative function.

    Full Text Available Abstract Background Efficient delivery strategies for health interventions are essential for high and sustainable coverage. We report impact of a change in programmatic delivery strategy from routine delivery through the Expanded Programme on Immunization (EPI+ approach to twice-yearly mass distribution campaigns on coverage of vitamin A supplementation in Tanzania Methods We investigated disparities in age, sex, socio-economic status, nutritional status and maternal education within vitamin A coverage in children between 1 and 2 years of age from two independent household level child health surveys conducted (1 during a continuous universal targeting scheme based on routine EPI contacts for children aged 9, 15 and 21 months (1999; and (2 three years later after the introduction of twice-yearly vitamin A supplementation campaigns for children aged 6 months to 5 years, a 6-monthly universal targeting scheme (2002. A representative cluster sample of approximately 2,400 rural households was obtained from Rufiji, Morogoro Rural, Kilombero and Ulanga districts. A modular questionnaire about the health of all children under the age of five was administered to consenting heads of households and caretakers of children. Information on the use of child health interventions including vitamin A was asked. Results Coverage of vitamin A supplementation among 1–2 year old children increased from 13% [95% CI 10–18%] in 1999 to 76% [95%CI 72–81%] in 2002. In 2002 knowledge of two or more child health danger signs was negatively associated with vitamin A supplementation coverage (80% versus 70% (p = 0.04. Nevertheless, we did not find any disparities in coverage of vitamin A by district, gender, socio-economic status and DPT vaccinations. Conclusion Change in programmatic delivery of vitamin A supplementation was associated with a major improvement in coverage in Tanzania that was been sustained by repeated campaigns for at least three years. There is a

    2008-01-01

    Abatement of soil-lead hazards may also reduce human exposure to other soil toxins, thereby achieving significant collateral benefits that are not accounted for today. This proposition was tested with the specific case of soil-arsenic, where 1726 residential soil samples were collected and analyzed for lead and arsenic. The study found that these two toxins coexisted in most samples, but their concentrations were weakly correlated, reflecting the differing sources for each toxin. Collateral benefits of 9% would be achieved during abatement of the lead-contaminated soils having elevated arsenic concentrations. However, a hidden hazard of 16% was observed by overlooking elevated arsenic concentrations in soils having lead concentrations not requiring abatement. This study recommends that soil samples collected under HUD programs should be collected from areas of lead and arsenic deposition and tested for arsenic as well as lead, and that soil abatement decisions consider soil-arsenic as well as soil-lead guidelines. - Coexistence of arsenic at elevated concentrations with lead in residential soils undergoing lead hazard assessment is often overlooked, providing either collateral benefits or hidden hazards

    As part of the Copenhagen Accord, individual countries have submitted greenhouse gas reduction proposals for the year 2020. This paper analyses the implications for emission reductions, the carbon price, and abatement costs of these submissions. The submissions of the Annex I (industrialised) countries are estimated to lead to a total reduction target of 12-18% below 1990 levels. The submissions of the seven major emerging economies are estimated to lead to an 11-14% reduction below baseline emissions, depending on international (financial) support. Global abatement costs in 2020 are estimated at about USD 60-100 billion, assuming that at least two-thirds of Annex I emission reduction targets need to be achieved domestically. The largest share of these costs are incurred by Annex I countries, although the costs as share of GDP are similar for Annex I as a group and the seven emerging economies as a group, even when assuming substantial international transfers from Annex I countries to the emerging economies to finance their abatement costs. If the restriction of achieving two-thirds of the emission reduction target domestically is abandoned, it would more than double the international carbon price and at the same time reduce global abatement costs by almost 25%.

  11. Non-thermal plasmas for non-catalytic and catalytic VOC abatement

    Vandenbroucke, Arne M.; Morent, Rino; De Geyter, Nathalie; Leys, Christophe

    2011-01-01

    Highlights: → We review the current status of catalytic and non-catalytic VOC abatement based on a vast number of research papers. → The underlying mechanisms of plasma-catalysis for VOC abatement are discussed. → Critical process parameters that determine the influent are discussed and compared. - Abstract: This paper reviews recent achievements and the current status of non-thermal plasma (NTP) technology for the abatement of volatile organic compounds (VOCs). Many reactor configurations have been developed to generate a NTP at atmospheric pressure. Therefore in this review article, the principles of generating NTPs are outlined. Further on, this paper is divided in two equally important parts: plasma-alone and plasma-catalytic systems. Combination of NTP with heterogeneous catalysis has attracted increased attention in order to overcome the weaknesses of plasma-alone systems. An overview is given of the present understanding of the mechanisms involved in plasma-catalytic processes. In both parts (plasma-alone systems and plasma-catalysis), literature on the abatement of VOCs is reviewed in close detail. Special attention is given to the influence of critical process parameters on the removal process.

  13. Valuation of marginal CO2 abatement options for electric power plants in Korea

    Park, Hojeong; Lim, Jaekyu

    2009-01-01

    The electricity generation sector in Korea is under pressure to mitigate greenhouse gases as directed by the Kyoto Protocol. The principal compliance options for power companies under the cap-and-trade include the application of direct CO 2 emission abatement and the procurement of emission allowances. The objective of this paper is to provide an analytical framework for assessing the cost-effectiveness of these options. We attempt to derive the marginal abatement cost for CO 2 using the output distance function and analyze the relative advantages of emission allowance procurement option as compared to direct abatement option. Real-option approach is adopted to incorporate emission allowance price uncertainty. Empirical result shows the marginal abatement cost with an average of Euro 14.04/ton CO 2 for fossil-fueled power plants and confirms the existence of substantial cost heterogeneity among plants which is sufficient to achieve trading gains in allowance market. The comparison of two options enables us to identify the optimal position of the compliance for each plant. Sensitivity analyses are also presented with regard to several key parameters including the initial allowance prices and interest rate. The result of this paper may help Korean power plants to prepare for upcoming regulations targeted toward the reduction of domestic greenhouse gases.

  15. Inefficient national environmental regulation as a signal of high abatement costs

    Steiner, U.

    1997-12-31

    This paper analyses the importance of informational asymmetries in international environmental regulation by use of a game theoretic approach of signaling games. More specific it analysis whether it is possible for a government to try to extract higher compensation in an international unidirectoral environmental problem. This may be possible when the national environmental regulation carries a signal of the cost of the regulated industry. In this case the government e.g. by means of inefficient environmental regulation on a national level may try to signal high abatement costs. In spite of the fact that many international environmental problems seem to be solvable by the use of financial payments there are only few examples that compensation payment arrangements have been implemented. As many countries and especially many polluting firms possess better information about abatement costs than the countries that receive the pollution, it is worthwhile to include asymmetric information. Consequently, this paper analyses whether the introduction of asymmetric information about abatement costs may bring forward incentives to misrepresent the true abatement cost in order to capture more compensation. If these incentives turn out to be present, it may explain some of the suspicion against using financial payment in order to induce other countries to join an agreement. The analysis shows that it may indeed be the case that the expected gain from cheating is so large that it gives incentives to use an inefficient national environmental policy. (au) 13 refs.

  16. Sustainable noise abatement along motorways in Germany – an empirical study in the municipality Frasdorf (Bavaria

    Jürgen Breuste

    2014-09-01

    Full Text Available As part of the planned expansion work of the motorway A8 between Rosenheim and Salzburg and the associated legal opportunity to develop new traffic noise protection measures, this study investigated properties of sustainable noise abatement in a community next to the A8. A two-stage empirical survey was conducted integrating a citizen and an expert Delphi survey. The results show that the noise from the motorway heavily affects the quality of life in health, economic and ecological respects. Sustainable noise abatement should take into consideration ecological and social aspects like landscape integration and contribution to local development due to the unique location of the municipality. Enclosed motorway canopies are particularly beneficial to meet these criteria. The costs for sustainable noise abatement measures should be weighted as less important; however, financial costs are crucial for the federal government due to the requirements of the Federal Pollution Control Act. Hence, residents and experts assume that noise barriers as the cheaper noise abatement measures will be implemented. However, the results of the study and the latest developments in the expansion plans suggest that the implementation of enclosed motorway canopies, which go beyond the legal requirements, is feasible through extensive citizen participation and community-specific planning.

  18. Reconciling sectoral abatement strategies with global climate targets: the case of the Chinese passenger vehicle fleet.

    Pauliuk, Stefan; Dhaniati, Ni Made A; Müller, Daniel B

    2012-01-03

    The IPCC Forth Assessment Report postulates that global warming can be limited to 2 °C by deploying technologies that are currently available or expected to be commercialized in the coming decades. However, neither specific technological pathways nor internationally binding reduction targets for different sectors or countries have been established yet. Using the passenger car stock in China as example we compute direct CO(2) emissions until 2050 depending on population, car utilization, and fuel efficiency and compare them to benchmarks derived by assuming even contribution of all sectors and a unitary global per capita emission quota. Compared to present car utilization in industrialized countries, massive deployment of prototypes of fuel efficient cars could reduce emissions by about 45%, and moderately lower car use could contribute with another 33%. Still, emissions remain about five times higher than the benchmark for the 2 °C global warming target. Therefore an extended analysis, including in particular low-carbon fuels and the impact of urban and transport planning on annual distance traveled and car ownership, should be considered. A cross-sectoral comparison could reveal whether other sectors could bear an overproportional reduction quota instead. The proposed model offers direct interfaces to material industries, fuel production, and scrap vehicle supply.

  19. Policies and strategies for meeting emission abatement targets in the UK electricity supply industry

    Kyte, W S [Powergen, Solihull (United Kingdom)

    1994-12-31

    A new electricity industry structure was created in the UK on 31 March 1990 and this was launched into the private sector during 1990/91. This structure differs considerably from the public corporations that preceeded it. Public awareness of the environment has grown during this period and the newly privatised electricity supply industry is having to implement new pollution controls. Legislation increasingly comes from the European Commission and is interpreted by HM Inspectorate of Pollution having regard to Best Practicable Environmental Option (BPEO) and Best Available Technology Not Entailing Excessive Cost (BATNEEC). Issues of particular importance include acid rain, and global warming - especially CO{sub 2} reduction. 3 figs.

  20. Innovative Strategies for Building Community Resilience: Lessons from the Frontlines of Climate Change Capacity-Building

    Abrash Walton, A.

    2017-12-01

    There is broad scientific consensus that climate change is occurring; however, there is limited implementation of measures to create resilient local communities (Abrash Walton, Simpson, Rhoades, & Daniels, 2016; Adger, Arnell, & Tompkins, 2005; Glavovic & Smith, 2014; Moser & Ekstrom, 2010; Picketts, Déry, & Curry, 2014). Communities that are considered climate leaders in the United States may have adopted climate change plans, yet few have actually implemented the policies, projects and recommendations in those plans. A range of innovative, education strategies have proven effective in building the capacity of local decision makers to strengthen community resilience. This presentation draws on the results of two years of original research regarding the information and support local decision makers require for effective action. Findings are based on information from four datasets, with more than 600 respondents from 48 U.S. states and 19 other countries working on local adaptation in a range of capacities. These research results can inform priority setting for public policy, budget setting, and action as well as private sector funding and investment. The presentation will focus, in particular, on methods and results of a pioneering Facilitated Community of Practice model (FCoP) for building climate preparedness and community resilience capacity, among local-level decision makers. The FCoP process includes group formation and shared capacity building experience. The process can also support collective objective setting and creation of structures and processes for ongoing sustainable collaboration. Results from two FCoPs - one fully online and the other hybrid - suggest that participants viewed the interpersonal and technical assistance elements of the FCoP as highly valuable. These findings suggest that there is an important need for facilitated networking and other relational aspects of building capacity among those advancing resilience at the local level.
