2017-03-01

The objective of the present research was to understand drivers' interaction patterns with hybrid electric vehicles' (HEV) eco-features (electric propulsion, regenerative braking, neutral mode) and their relationship to fuel efficiency and driver characteristics (technical system knowledge, eco-driving motivation). Eco-driving (driving behaviors performed to achieve higher fuel efficiency) has the potential to reduce CO 2 emissions caused by road vehicles. Eco-driving in HEVs is particularly challenging due to the systems' dynamic energy flows. As a result, drivers are likely to show diverse eco-driving behaviors, depending on factors like knowledge and motivation. The eco-features represent an interface for the control of the systems' energy flows. A sample of 121 HEV drivers who had constantly logged their fuel consumption prior to the study participated in an online questionnaire. Drivers' interaction patterns with the eco-features were related to fuel efficiency. A common factor was identified in an exploratory factor analysis, characterizing the intensity of actively dealing with electric energy, which was also related to fuel efficiency. Driver characteristics were not related to this factor, yet they were significant predictors of fuel efficiency. From the perspective of user-energy interaction, the relationship of the aggregated factor to fuel efficiency emphasizes the central role of drivers' perception of and interaction with energy conversions in determining HEV eco-driving success. To arrive at an in-depth understanding of drivers' eco-driving behaviors that can guide interface design, authors of future research should be concerned with the psychological processes that underlie drivers' interaction patterns with eco-features.

Does Nationality Matter in Eco-Behaviour?

Directory of Open Access Journals (Sweden)

Michelle Bonera

2017-09-01

Full Text Available Although many authors agree on the role of personal values in explaining the main determinants of eco-behaviour, disagreement about the effects of socio-demographic features exists, particularly about the effect of nationality. In an attempt to fill this gap in the literature, this paper contributes to the debate surrounding the main determinants of eco-behaviour, based on a cross-country analysis. To test the role of nationality and personal values in eco-behaviour, a linear regression model involving 353 Chinese and 333 Italian subjects was performed. A stepwise analysis was then conducted to identify the main significant effects. The explorative and stepwise analyses confirmed that nationality is significant when explaining individual eco-behaviour, for both Italian and Chinese people. Moreover, the linear regression model, as a stepwise analysis, showed that regulatory focus and universalism are the main personal values influencing ecological behaviour. Differences emerging from the analysis show significant differences in terms of eco-behaviour and eco-awareness, for the two countries involved in the analysis, that might lead companies to adopt different marketing strategies when promoting eco-products.

Eco-Innovation in Circular Agri-Business

Dong-Her Shih

2018-04-01

Full Text Available This study constructs a theory of eco-innovation in circular agri-business. Although previous studies have discussed eco-innovation in circular agri-business, they did not address eco-innovation from the perspective of a closed-loop sustainable supply chain. Hence, this study applied the fuzzy TOPSIS method to conduct the analysis and determine the interrelationship between eco-innovation and the closed-loop concept. The results are consistent with the theory and a significant improvement in terms of the decisive attributes. The findings suggest that improving water management, relationships with suppliers, knowledge sharing, environmental management systems, and new product and service development are the most effective and efficient ways to build eco-innovation in circular agri-business. The managerial and theoretical implications are discussed.

Umberto Eco - autobiograf?

Directory of Open Access Journals (Sweden)

Regina Lubas-Bartoszyńska

2009-01-01

Full Text Available This text shows that U. Eco is an autobiographer in only some sense of the word. He has not written an autobiobiographical text in which he would present a segment of his life. However, he told the history of his novelistic work and presented his intellectual train of thought in his essays, interviews, introductions to his works. There also exists an indirect autobiographism in Eco, which expresses signs of the author's life and of his personality dispersed in his interpretative and theoretical writings on literature, aesthetics, history, in his feuilletons and in his novels. Five types of autobiographism have been distinguished in Eco as well as five autobiographical strategies within the indirect autobiographism. The first strategy - a strong presence of autorial I in the text - is not sufficient and requires support of some other of the strategies discussed.

Full Text Available Eco-innovation is any form of innovation resulting in or aiming at significant and demonstrable progress towards the goal of sustainable development, through reducing impacts on the environment, enhancing resilience to environmental pressures, or achieving a more efficient and responsible use of natural resources. States and governments of the world, different institutions and organizations actively involved and aware in public policies, strategies and actions, reaffirm their commitments and reassess actions in order to achieve a truly sustainable development. In the common vision and the resolutions and other documents of the United Nations Conference on Sustainable Development, Rio+20, the words "environment", "innovation", "green economy" appear very often and almost always along the same context, to achieve the objectives of the sustainable development. The objectives of EU's Europe 2020 strategy for smart, sustainable and inclusive growth, are being implemented through a number of Flagship Initiatives addressing the main challenges, like “Innovation for a sustainable Future - The Eco-innovation Action Plan (EcoAP”. Eco-innovation Observatory developed the Eco-Innovation index, the first tool to assess and illustrate eco-innovation performance across the EU Member States. Like in all fields, in textiles and leather field, eco-innovation is present and there are a lot of tools available that measure environmental damage and help manufacturers and brands become more sustainable. Eco-innovation is not just a trendy concept but a reality and a necessity nowadays, a way to achieve a sustainable future for ourselves and future generations.

The goal is to promote the disciplinary development of eco-hydrology, and serve for national demands on ecological civilization construction in China.

Feedback-Based Eco-Design for Integrating the Recency, Frequency, and Monetary Value of Eco-Efficiency into Sustainability Management

Directory of Open Access Journals (Sweden)

Rui Yang Chen

2016-09-01

Full Text Available Customer feedback is used to understand customer requirements. Early design phases require the consideration of items including manufacturing, the environment, and sustainability management. Therefore, it is crucial that eco-efficiency is taken into account in the early design phases. Traditionally, eco-efficiency is considered only in terms of eco-design issues, not customer requirements based on business values such as Recency, Frequency, and Monetary (RFM value. In the meantime, integrating innovation from eco-design is one important aspect. Here, I propose that customer feedback-based eco-efficiency and TRIZ-based innovation can be considered in early eco-design based on the RFM value for sustainability management. The analytic hierarchy process (AHP and fuzzy-based AHP were integrated to explore the relative weights of RFM variables for business value evaluation. The innovative method of the paper is using a TRIZ contradiction matrix associated with engineering parameters for eco-design. The experimental study has been carried out, and it meets the forecasting business value for green product usage. The business value was used as the decision-making factor in order to evaluate both environmental and marketing performance.

The development of entrepreneurships in the 21st century cannot occur without taking care of the natural environment. The article presents issues related to eco-innovation. Despite the opportunities offered by eco-innovations, implementation of such initiatives remains to lead to various difficulties. They vary across countries and sectors. The insufficient number of enterprises in Poland and other European countries implement adequate level of eco-innovations. The main aim of this paper is to indicate the causes of this status and activities aimed to develop eco-innovativeness. The benefits and risks connected with implementation of innovative products and technologies were also discussed. Furthermore, the advantages of and barriers to their implementation into companies were analysed. The entrepreneurs from the least eco-innovative countries emphasize serious barriers, including uncertain demand from the market, uncertain return on investment or too long a payback period for eco-innovation, lack of funds within the enterprise, insufficient access to existing subsidies and fiscal incentive. They are especially afraid of the financial risks, which raises uncertainty and leads to refraining from innovative initiatives. The possibilities were indicated for the entrepreneurs who face problems with the implementation of innovative solutions. Particular attention was paid to the European Union activities for the development of eco-innovations. Numerous programs supporting their implementation were indicated. The article also presents examples of eco-innovation in water and sewage enterprises. It was emphasized that planning of eco-innovative solutions should be based on comprehensive information about actual benefits and possibility of threats to the environment which can be caused by implementation of eco-innovations. The study presents the example of threats resulting from different methods of sewage sludge management. Copyright © 2017 Elsevier Inc. All rights

To integrate measurements of eco-efficiency with control loop configuration has become an important topic since all industrial processes/plants are requested to increase their eco-efficiency. The exergy eco-efficiency factor, a new measure of eco-efficiency for control loop configuration, has been developed recently. The exergy eco-efficiency factor is based on the thermodynamic concept of exergy, which can be used to analyze a process in terms of its efficiency. The combination of the relative gain array (RGA), NI, CN, dynamic RGA, and the exergy eco-efficiency factor will help guide the process designer to find the optimal control design with low operating cost/eco-efficiency. In this paper, we validate the proposed exergy eco-efficiency factor for processes with recycles which are very common industrially.

This study measures productive inefficiency within the context of multi-environmental pollution (eco-efficiency) in the Chinese industrial sector. The weighted Russell directional distance model is applied to measure eco-efficiency using production technology. The objective is to clarify how external factors affect eco-efficiency. The major findings are that both foreign direct investment and investment for pollution abatement improve eco-efficiency as measured by air pollutant substances. A levy system for wastewater discharge improves eco-efficiency as measured by wastewater pollutant substances. However, an air pollutant levy does not significantly affect eco-efficiency as measured by air pollutants.

This study adds new insights to the long-running corporate environmental-financial performance debate by focusing on the concept of eco-efficiency. Using a new database of eco-efficiency ratings, we analyze the relation between eco-efficiency and financial performance from 1997 to 2004. We report that eco-efficiency relates positively to operating performance and market value. Moreover, our results suggest that the market's valuation of environmental performance has been time variant, which may indicate that the market incorporates environmental information with a drift. Although environmental leaders initially did not sell at a premium relative to laggards, the valuation differential increased significantly over time. Our results have implications for company managers, who evidently do not have to overcome a tradeoff between eco-efficiency and financial performance, and for investors, who can exploit environmental information for investment decisions

Full Text Available Utilization of eco-font for office printing is one of sustainable, “green” printing concepts, which besides obvious economic benefits, as a result has a certain effect on environmental sustainability as well. The fundamental problem that this practice faces is decreased quality of text printed using eco-fonts comparing to those printed with regular fonts. The aim of this research is eco-font efficiency estimation, i.e. determination of toner usage reduction level of ink jet printed documents typed with this font type, as well as estimation of the extent humans perceive differences between text printed with eco-font and the one printed by its „non-eco“ equivalent. Combining instrumental measuring method and digital image analysis, it was found that this simple principle (eco-font utilization enables substantial toner usage reduction for an ink jet printing system, while visual test showed that visual experience of text printed using eco-font is sufficient. In addition, awareness of benefits that eco-font utilization brings, change users’ attitude towards eco-font quality.

Full Text Available Eco-certification has become an increasingly popular market-based tool in the endeavor to reduce negative environmental impacts from fisheries and aquaculture. In this study, we aimed at investigating which psychological consumer characteristics influence demand for eco-labeled seafood by correlating consumers’ stated purchasing of eco-labeled seafood to nine variables: environmental knowledge regarding seafood production, familiarity with eco-labels, subjective knowledge, pro-environmental self-identification, sense of personal responsibility, concern for negative environmental impacts from seafood production, perceived consumer effectiveness, gender and education. Questionnaires were distributed to consumers in Stockholm, Sweden, and the data were tested with multiple regression analysis using linear modeling and model averaging (n = 371. Two variables were the best predictors of stated purchasing of eco-labeled seafood: (i recognition and understanding of eco-labels for seafood (Marine Stewardship Council, Fish for Life, Aquaculture Stewardship Council and KRAV; and (ii concern for negative environmental impacts associated with seafood production. Meanwhile, consumer environmental knowledge was a weaker predictor. Results from this study suggest that strengthening the emotional component of consumer decision-making and improving the level of consumer familiarity with seafood eco-labels could stimulate more pro-environmental seafood consumption.

Surgical resection of epileptogenic foci is often a beneficial treatment for patients suffering debilitating seizures arising from intractable epilepsy [1], [2], [3]. Electrodes placed subdurally on the surface of the brain in the form of an ECoG array is one of the multiple methods for localizing epileptogenic zones for the purpose of defining the region for surgical resection. Currently, transcutaneous wires from ECoG grids limit the duration of time that implanted grids can be used for diagnosis. A wireless ECoG recording and stimulation system may be a solution to extend the diagnostic period. To avoid the transcutaneous connections, a 64-channel wireless silicon recording/stimulating ASIC was developed as the electronic component of a wireless ECoG array that uses SIROF electrodes on a polyimide substrate[4]. Here we describe two new ASIC devices that have been developed and tested as part of the on-going wireless ECoG system design.

Considering climate warming as an immediate threat for humanity, ecologists from the Eco-modernism movement not only approve but call for the presence of nuclear power in the energy mix. For them nuclear energy is a mature low-carbon energy that can be used to combine all renewable energies more efficiently. NGO like 'Environmental Progress', 'Energy for Humanity' or 'Save the Nukes' back the Eco-modernism movement. The Eco-modernism movement gathers unconventional ecologists who consider that modern technologies by using the eco-system more efficiently than previous technologies did, are a powerful tool to reduce the global impact of humane activities on the biosphere. The Eco-modernism movement is for agricultural intensification, the use of GMO, waste recycling and for increasing urbanization. (A.C.)

To bridge this seemingly measurement gap, this paper suggests ‘Eco-Ratio Analysis’ and proposes an approach for conducting eco-ratio analysis. It is argued that since accounting ratios function as a tool for evaluating corporate financial viability by management and investors, eco-ratio analysis should be brought to the fore to provide a succinct measurement about the linkage between environmental performance and conventional business performance. It is hoped that this suggestion will usher in a nuance debate and approach in the teaching, research and practice of environmental management and sustainability accounting

ECO-INDUSTRIAL PARK - A TOOL FOR SUSTAINABLE DEVELOPMENT

Directory of Open Access Journals (Sweden)

BUGNAR NICOLETA GEORGETA

2013-07-01

Full Text Available Local communities embracing the concept of Eco-industrial park are looking for some additional benefits for all the interested parties – both public and private: higher economic efficiency, the increase of competitivity by applying last minute technologies, generation of additional revenues through positive regulations at the community level, the creation of jobs, solving the conflict between economy and environment, diminishing the demand on the county infrastructure, decreasing the effects of pollution, using energy from regenerating sources and replacement materials. Communities and enterprises creating Eco-industrial parks will have common grounds for industrial development, which is much more competitive, more efficient and much cleaner than traditional industrial parks. Moreover, the new business niches will be open to recruitment or new incubators. Eco-industrial parks represent a special category compared to industrial parks, a category which is different from the classical ones due to the fact that they are designed in such a way so that they promote the collaboration between companies in order to reuse recyclable materials and green energy sources. A long-term vision must reflect the focus on the creation of collaboration networks between firms and the fact that an Eco-industrial park should be a business community, not only a mathematical sum of companies located in the same geographical area. The quality, continuity and interconnection of economic flows within the firms of an Eco-industrial park are important characteristics for the success of Eco-industrial networks. The following discussion tackles the way in which an Eco-industrial park is set-up: creating and implementing an Eco-industrial park in accordance with the principles of circular economy or transforming an already existing industrial park into an Eco- industrial park. The quality, the continuity, the number of interconnected firms, the flows of resources and the

An optimization problem of two eco-energetic systems is described. The first one is close to the actual eco-energetic system in Romania, while the second is a new one, based on nuclear energy as primary source and hydrogen energy as secondary source. The optimization problem solved is to find the optimal structure of the systems so that the objective functions adopted, namely unitary energy cost C and total pollution P, to be minimum at the same time. The problem can be modelated with a bimatrix cooperative mathematical game without side payments. We demonstrate the superiority of the new eco-energetic system. (author)

Shedding Light on Eco-Innovation in Tourism: A Critical Analysis

Directory of Open Access Journals (Sweden)

Maria-del-Mar Alonso-Almeida

2016-12-01

Full Text Available The recent global increase in the competitiveness of tourism has made the implementation of eco-innovations a differentiating element among both the destinations and companies in the sector, with quality management and contribution to sustainable development being increasingly valued. However, the eco-innovations that have been developed and implemented in tourist industries have rarely been studied. In this study, the eco-innovations that have been developed and implemented by 57 tourism businesses worldwide are analysed. The identified eco-innovations are classified by using different qualitative methodologies. The obtained results shed light on the limited development of eco-innovations in the tourism industry and the industry focuses mainly on product eco-innovations. Several examples by the tourist sub-industry and types of eco-innovation are analysed. Furthermore, this study provides practical information about measures that both businesses and governmental organisations can adopt to promote eco-innovation in the sector.

Enabling Eco-Friendly Choices by Relying on the Proportional-Thinking Heuristic

Cleotilde Gonzalez

2013-01-01

Full Text Available Ecological (eco taxes are promising mechanisms to enable eco-friendly decisions, but few people prefer them. In this study, we present a way in which eco-tax options may be communicated to general public to encourage their payment. Our implementation (called “information presentation” takes advantage of the non-linear relationship between eco-tax payments and CO2 emissions and the human reliance on the proportional-thinking heuristic. According to the proportional-thinking heuristic, people are likely to prefer a small eco-tax increase and judge larger eco-tax increases to cause proportionally greater CO2 emissions reductions. In an online study, participants were asked to choose between eco-tax increases in two problems: In one, a smaller eco-tax increase resulted in greater CO2 emissions reduction, while in the other, a smaller tax increase resulted in lesser CO2 emissions reduction. Although the larger eco-tax increase did not reduce CO2 emissions the most, across both problems, people judged larger eco-tax increases to cause proportionally greater reductions in CO2 emissions and preferred smaller tax increases. Thus, eco-tax policies would benefit by presenting information in terms of eco-tax increases, such that smaller eco-tax increases (which are more attractive and are likely to be chosen by people cause greater CO2 emissions reductions.

Full Text Available The study of universities and their role in enterprise development, support and education is very mature. However when Isenberg coined the term ‘entrepreneurial ecosystem’ and suggested that higher education was one of the key foundation blocks of a regional eco-system it threw open the concept of the university having a wider role in the overall business, economic and civic life of a region. What is this wider role, and how do the universities themselves view their place in this evolving entrepreneurial eco-system? How do they fit into Regional Alliances set up to build regional economic development? This paper introduces two pilot Alliances that have been recently formed using both the education institutes and the wider eco-system to drive Innovation and Graduate Employability (The SHIP and REAL Alliances.

SUSTAINABLE ECONOMIC GROWTH AND ECO-EFFICIENCY

Directory of Open Access Journals (Sweden)

Mariana\tLUPAN

2015-06-01

Full Text Available The current economic and social contexts have brought forth the issues regarding growth and sustainability. The concept of growth has always been linked to an increase in consumption levels, and this inevitably led to pressures on the environment and on the resources that support human activity. Given these circumstances, the question whether we can avoid an environmental disaster while maintaining economic growth, has become more stringent. We chose to approach this aspect by examining the concept of eco-efficiency, a concept that embodies aspects of both economic efficiency and environmental efficiency. Eco-efficiency can be regarded as the effectiveness with which resources are used in order to create products and services that satisfy human needs. Based on this idea, the last decade has produced an increasing number of studies on eco-efficiency and how it can be measured and implemented in the production of goods and services, but also in the field regarding demand patterns. An analysis regarding the aspects of eco-efficiency at the macro level of the Romanian economy is in line with the current environmental concerns, thus I have chosen to cover these questions, as well as the evolution of the locale economy towards a more sustainable development. The outcome of the examined aspects shows that, in spite of an increase in eco-efficiency levels, energy and material consumption and emissions have increased. This raises the question if measuring economic and environmental efficiency by reporting to the GDP value is becoming obsolete and if there is a need to revaluate eco-efficiency indicators in order to measure the transition to a greener and more sustainable development from different points of view.

In the last decades, majority of automakers started to include lightweight materials in their vehicles to meet hard environmental regulations and to improve fuel efficiency of their vehicles. As a result, eco-material selection for vehicles emerged as a new discipline under design for environment. This chapter will summarize methods of eco-material selections for automotive applications with more emphasis into auto-bodies. A set of metrics for eco-material selection that takes into account all economic, environmental and social factors will be developed using numerical and qualitative methods. These metrics cover products' environmental impact, functionality and manufacturability, in addition to the economic and societal factors.

Proposal for the Evaluation of Eco-Efficient Concrete

Directory of Open Access Journals (Sweden)

Taehyoung Kim

2016-07-01

Full Text Available The importance of environmental consequences due to diverse substances that are emitted during the production of concrete is recognized, but environmental performance tends to be evaluated separately from the economic performance and durability performance of concrete. In order to evaluate concrete from the perspective of sustainable development, evaluation technologies are required for comprehensive assessment of environmental performance, economic performance, and durability performance based on a concept of sustainable development called the triple bottom line (TBL. Herein, an assessment method for concrete eco-efficiency is developed as a technique to ensure the manufacture of highly durable and eco-friendly concrete, while minimizing both the load on the ecological environment and manufacturing costs. The assessment method is based on environmental impact, manufacturing costs, and the service life of concrete. According to our findings, eco-efficiency increased as the compressive strength of concrete increased from 21 MPa to 40 MPa. The eco-efficiency of 40 MPa concrete was about 50% higher than the eco-efficiency of 24 MPa concrete. Thus eco-efficiency is found to increase with an increasing compressive strength of concrete because the rate of increase in the service life of concrete is larger than the rate of increase in the costs. In addition, eco-efficiency (KRW/year was shown to increase for all concrete strengths as mixing rates of admixtures (Ground Granulated Blast furnace Slag increased to 30% during concrete mix design. However, when the mixing rate of admixtures increased to 40% and 60%, the eco-efficiency dropped due to rapid reduction in the service life values of concrete to 74 (year/m3 and 44 (year/m3, respectively.

Eco-ethology

Krebs, J.R.; Davies, N.B.

1981-01-01

Eco-ethology is the science of the effects of animal behaviour on animal environment and the effects of animal environment on animal behaviour, with the purpose to find out how natural selection within this control loop has formed and molded animals. N. Tinbergen was the first to make experiments on the evolution of patterns of behaviour which are influenced not only by the evolution of species but also by their adaptation to a changing environment. R.H. MacArthur then introduced mathematical modelling for better clarification of the function and adoptive value of behavioural patterns. The book gives a detailed description of both methods and a successful attempt at a synthesis. In surveys and specific contribution, an exemplary outline of eco-ethology is presented, with information, ideas and reflections that are of interest both to teachers and students. The book is addressed to biologists, zoologists, ecologists, sociologists, and evolutionary biologists and to students of these disciplines. (orig.) [de

During COP21, Schneider Electric has committed that 100% of our new products would be eco-designed to tackle climate change. Launched in 2015, this initiative ecoDesign WayTM was tested on some pilot projects. This project covers the first ecoDesign WayTM pilot in China on an overvoltage or under voltage protective device used in both residential and industrial sectors, called Monsoon. Under the name ecoDesign WayTM, a method and a process have been deployed. The 3 main ecoDesign WayTM phases are: phase 1 - Marketing & Technique handshake, Phase 2 - ecoDesign WayTM follow-up and Phase 3 - Marketing communication. During the project, EIME from Bureau Veritas CODDE and ecoDesign WayTM scorecard from EVEA consulting are two core tools for eco-design implementation. They are respectively used for life cycle assessment and eco-design performance comparison. Thanks to the approach, compared to previous range, pollution emissions and resource depletion along the whole life cycle of product have decreased (reduction of 55% for energy depletion and 85% for water depletion). Global warming potential has dramatically decreased by 98.4% and air pollution by 33%. Meanwhile, the recycling rate has been improved by 18%, and recycled PA is used. The ecoDesign WayTM scorecard is stored as referent document for any customer request. Moreover, customers can access RoHS certificate, REACh declaration, PEP and EoLI in Check a product, an online environmental data repository, available 24/7.

According to a recent announcement, Eco Logic of Rockwood, Ontario, has entered into a partnership with the Japanese companies Tokyo Boeki and Nippon Sharyo for the destruction of stockpiled PCB materials in Japan, using Eco Logic's non-incineration technology. The deal is reported to be worth about $50 million in revenues to Eco Logic, spread over the next few years. The agreement includes provisions for the Japanese companies to purchase, or manufacture under licence, a number of Eco Logic's gas phase chemical reduction processing units to serve the Japanese market. In exchange for exclusive rights to the Japanese market, Eco Logic will receive license fees and royalties of up to nine per cent for the use of its process. Eco Logic is currently building a demonstration unit under contract with the two Japanese companies. The Japanese PCB waste destruction market is estimated to be worth as much as $400 million. Incineration, the conventional form of disposal, is strongly opposed by local governments

Participants tasted two cups of coffee, decided which they preferred, and then rated each coffee. They were told (in lure) that one of the cups contained "eco-friendly" coffee while the other did not, although the two cups contained identical coffee. In Experiments 1 and 3, but not in Experiment 2, the participants were also told which cup contained which type of coffee before they tasted. The participants preferred the taste of, and were willing to pay more for, the "eco-friendly" coffee, at least those who scored high on a questionnaire on attitudes toward sustainable consumer behavior (Experiment 1). High sustainability consumers were also willing to pay more for "eco-friendly" coffee, even when they were told, after their decision, that they preferred the non-labeled alternative (Experiment 2). Moreover, the eco-label effect does not appear to be a consequence of social desirability, as participants were just as biased when reporting the taste estimates and willingness to pay anonymously (Experiment 3). Eco labels not only promote a willingness to pay more for the product but also lead to a more favorable perceptual experience of it.

Full Text Available In today's world, it is very necessary to understand the importance of being eco-friendly in every facet of our lives. The color “green” has healing power and denotes renewal, growth, and hope. “Eco-friendly dentistry” attempts to reduce the detrimental impact of dental practices on the environment and promote environmental awareness and sustainability to patients. This paper attempts to cover all possible aspects of making a dental practice eco-friendly, both in a dental perspective as well as a general perspective. While establishing an eco-friendly dental workplace, the dentist needs to assess his choices in planning the infrastructure and purchasing of equipment and dental materials. Eco-friendly dentistry is a newly evolving practice of dentistry, which encompasses a simultaneous devotion to sustainability, prevention, precaution, and a minimally invasive patient-centric, as well as global-centric treatment. There are two main avenues for implementing eco-friendly dentistry: (1 appropriate policy development and implementation and (2 dentists taking responsibility/ownership in the absence of policies and regulations. Although in some cases, it may take a little extra effort or money; dentists throughout the world are doing their best to reduce the environmental impact of the dental practice. Although the commitment of one small dental office cannot save the planet, certainly, the collective efforts of many small offices as well as large dental hospitals/colleges can ensure that dentists, at least, will not be responsible for destroying it. This article discusses various factors that can be incorporated into dental practice that can help make dentistry eco-friendly.

Eco-Efficiency Actions and Firm Growth in European SMEs

Directory of Open Access Journals (Sweden)

Elisenda Jové-Llopis

2018-01-01

Full Text Available This study investigates the effects of eco-efficiency actions on firm performance in terms of sales growth in an extensive sample of 11,336 small- and medium-sized enterprises (SMEs located in 28 European countries. Our empirical results suggest that not all eco-strategies are positively related to better performance, at least not in the short term. We found that European companies using renewable energies, and recycling or designing products that are easier to maintain, repair, or reuse, perform better. Those that aim to reduce water or energy pollution, however, seemed to show a negative correlation to firm growth. Our results also indicate that high investment in eco-strategies improves firm growth, particularly in new members that joined the EU from 2004 onwards. Finally, we observed a U-shaped relationship between eco-strategies and firm growth, which indicates that a greater breadth of eco-strategies is associated with better firm performance. However, few European SMEs are able to either invest heavily or undertake multiple eco-strategies, thus leaving room for policy interventions.

Soil eco-toxicology provides a theoretical basis for ecological risk assessment of contaminated soils and soil pollution control. Research on eco-toxicological effects and molecular mechanisms of toxic substances in soil environment is the central content of the soil eco-toxicology. Eco-toxicological diagnosis not only gathers all the information of soil pollution, but also provides the overall toxic effects of soil. Therefore, research on the eco-toxicological diagnosis of soil pollution has important theoretical and practical significance. Based on the research of eco-toxicological diagnosis of soil pollution, this paper introduced some common toxicological methods and indicators, with the advantages and disadvantages of various methods discussed. However, conventional biomarkers can only indicate the class of stress, but fail to explain the molecular mechanism of damage or response happened. Biomarkers and molecular diagnostic techniques, which are used to evaluate toxicity of contaminated soil, can explore deeply detoxification mechanisms of organisms under exogenous stress. In this paper, these biomarkers and techniques were introduced systematically, and the future research trends were prospected.

Full Text Available An important goal of fisheries management is to ensure that fish stocks are harvested at sustainable levels of fishing pressure. However, the classical maximum sustainable yield theory and its derivatives have not worked for fisheries management. A number of mitigating measures have been suggested of which eco -labeling is one. An ecolabel on a fish product is a distinctive mark or statement indicating that it has been harvested in compliance with preset sustainability standards. This paper examines eco labeling in fisheries as the new strategy to achieve fisheries conservation and sustainability. It emphasizes the importance of fish as critical food resources and new approach to fisheries management through the use of certification programs. It considers the benefits and problems that may accrue from eco-certification of fish harvesting and trade practices in fisheries. This paper, attention is focused on examining the likely option for development of eco-labeling scheme in Nigeria. The paper concludes that the increase awareness amongst stakeholders of the potential role of eco-labeling in conservation and sustainability tools should be established.   Keywords: Fisheries management, fish, conservation, eco-certification

travel costs. Based on the techniques above, different histogram aggregation methods are proposed to accurately estimate time-dependent GHG emissions for routes. Based on a 200-million GPS record data set collected from 150 vehicles in Denmark over two years, a comprehensive empirical study is conducted...... transportation. The foundation of eco-routing is a weighted-graph representation of a road network in which road segments, or edges, are associated with eco-weights that capture the GHG emissions caused by traversing the edges. Due to the dynamics of traffic, the eco-weights are best modeled as being time...... dependent and uncertain. We formalize the problem of assigning a time-dependent, uncertain eco-weight to each edge in a road network based on historical GPS records. In particular, a sequence of histograms is employed to describe the uncertain eco-weight of an edge at different time intervals. Compression...

Eco-design is crucial to take environmental aspects into account in the phases of design. Few literature review that green product must meet market value. The development of models to predict market value is thus very useful because it can provide early eco-efficiency to the eco-design. For the eco-design engineer, when he tries to solve a customer feedback problem, he usually faces the eco-efficiency. There are, however, often other types of fuzziness uncertainty present, which are related to the quantity of eco-design conditions. In this paper, it is derived that analysis of eco-efficiency can be identified by using the RFM value for quantifying eco-design with Takagi-Sugeno fuzzy system on customer feedback problem. It clusters eco-efficiency into segments according to green product usages value expressed in terms of weighted RFM. This experiment examined the weighted RFM effect of overall average normalized, AHP and non-weighted for F1 metric. The experimental results show that the proposed methodology indeed can yield identification of higher quality

With the advance of internet and wireless communication technology, the fields of ecology and environment have entered a new digital era with the amount of data growing explosively and big data technologies attracting more and more attention. The eco-environmental big data is based airborne and space-/land-based observations of ecological and environmental factors and its ultimate goal is to integrate multi-source and multi-scale data for information mining by taking advantages of cloud computation, artificial intelligence, and modeling technologies. In comparison with other fields, the eco-environmental big data has its own characteristics, such as diverse data formats and sources, data collected with various protocols and standards, and serving different clients and organizations with special requirements. Big data technology has been applied worldwide in ecological and environmental fields including global climate prediction, ecological network observation and modeling, and regional air pollution control. The development of eco-environmental big data in China is facing many problems, such as data sharing issues, outdated monitoring facilities and techno-logies, and insufficient data mining capacity. Despite all this, big data technology is critical to solving eco-environmental problems, improving prediction and warning accuracy on eco-environmental catastrophes, and boosting scientific research in the field in China. We expected that the eco-environmental big data would contribute significantly to policy making and environmental services and management, and thus the sustainable development and eco-civilization construction in China in the coming decades.

Jie Zhou

2015-07-01

Full Text Available This paper discusses vegetarian eco-feminist consciousness in Carol Ann Duffy’s poetry by close analysis of two poems, namely “The Dolphins” and “A Healthy Diet” from her poem collection Standing Female Nude. The former is a dramatic monologue of a dolphin, which is exploited by people, and the latter is a dramatic monologue of an omnipotent observer in a restaurant. Both poems criticized the species-ism, and together, they showed the poet’s vegetarian eco-feminist consciousness. A close reading of the two poems from the eco-feminist perspective helps the reader understand why Carol Ann Duffy is honored as the first woman poet laureate in British history, and better understand vegetarian eco-feminism and its influence in British society.

Regional eco-environmental quality is the key and foundation to the sustainable socio-economic development of a region. Eco-environmental quality assessment can reveal the capacity of sustainable socio-economic development in a region and the degree of coordination between social production and the living environment. As part of a new development strategy for Fujian Province, the Western Taiwan Straits Economic Zone (hereafter referred to as the Economic Zone) provides an important guarantee for the development of China's southeastern coastal area. Based on ecological and remote sensing data on the Economic Zone obtained in 2000, 2005, and 2010, this study investigated county-level administrative regions with a comprehensive index of eco-environmental indicators. An objective weighting method was used to determine the importance of each indicator. This led to the development of an indicator system to assess the eco-environmental quality of the economic zone. ArcGIS software was used to assess the eco-environmental quality of the economic zone based on each indicator. The eco-environmental quality index (EQI) of the county-level administrative regions was calculated. The overall eco-environmental quality of the Economic Zone during the period studied is described and analyzed. The results show that the overall eco-environmental quality of the Economic Zone is satisfactory, but significant intraregional differences still exist. The key to improving the overall eco-environmental quality of this area is to restore vegetation and preserve biodiversity.

The Eco House

Energy Technology Data Exchange (ETDEWEB)

Hobbett, A. (Leicester Ecology Trust (United Kingdom))

The Eco House is a former park keeper's lodge on the periphery of Leicester's largest public park. Taken over by Leicester Ecology Trust in 1990, the Eco House was a successor to the Trust's earlier low energy house. This has been a local authority decant house, retrofitted to show the potential for increased energy efficiency in older buildings. Many of the ideas from the earlier project were adopted by the new with a widening of its remit to include all matters of environmental concern connected with people's homes. So in addition to energy efficiency, other issues addressed include conservation of resources, wildlife, organic gardening, food production, water, environmental consumerism, recycling and health. Given that the use of energy is regarded by many environmentalists to be the single most important environmental issue today, and one which is easiest for households to address, it remains the project's dominant theme.

Jang-Hwan Jo

2015-12-01

Full Text Available Following the trend on focusing on a nation’s economic-growth, side effects such as resource exhaustion, environmental pollution, and social injustice have begun to appear. As a solution, eco-innovation has received a great amount of attention from European countries and as a result, many efforts to analyze the development of eco-innovation quantitatively have been made. This study aims to evaluate the validity of an eco-innovation index developed to support the sustainable development goal. For this purpose, four factors of eco-innovation—capacity, supportive environment, activity, and performance—were applied to three categories of the Triple-Bottom-Line (TBL concept in sustainability to compare the eco-innovation development level of 49 Asia-Europe Meeting countries. Factors for eco-innovation and TBL at the country level were organized in quartile and compared to see strength and weaknesses for each nation. In order to test if eco-innovation factors of a nation adequately reflect its sustainability, we used various comparisons of ANOVA. The results of this study are as follows: First, the one-way ANOVA tests present the scores for capacity, supportive environment, and performance as grouped into four quartiles in the same pattern as their economic, social, and environmental scores. The three-way ANOVA tests showed significance for the economic category. Scores for capacity, supportive environment, activity and performance were significant at a nation’s economic level. Lastly, the MANOVA test revealed that TBL significantly explains four eco-innovation factors. In addition, the eco-innovation performance level of European nations and Asian nations were compared. The possibility that many nations still have room to be competitive in their eco-innovation efforts was identified. Nations with unbalanced eco-innovation growth are urged to implement new strategies to balance their growth. Therefore, this research contributes to extending

The Application Potential of Eco-Efficiency for Greening Company

Prasaja, Lukman Eka; Hadiyanto

2018-02-01

Eco-Efficiency emerged in the 1990s as a measure of "the efficiency that ecological sources use to meet human needs." As a tool in economic and environmental integration, Eco-efficiency needs to be promoted further so that regulation in government and industrial management can include it as an important instrument. This paper provides several approaches that can help various industries to develop effective eco-efficiency principles. The approach used is to maximize the role of the Steering Committee of the company's internal environment. Utilization of natural resources such as water, forests, mines and energy needs need to be balanced with Eco-Efficiency so that natural exploitation can be well controlled so that sustainable development aspired by the world can be realized.

Eco-labelling of shampoos, shower gels and foam baths.

Environmental issues of personal care products have been met with little attention in the past. Monitoring data as well as preliminary environmental risk assessments indicate that some ingredients in personal care products might be relevant pollutants in the environment. Following the precautionary principle, eco-labelling is proposed as an effective tool for source control of one major group of personal care products, shampoos, shower gels and foam baths (SSBs). Eco-labelling is a soft, but effective market driven and product specific approach to lower discharge of environmentally detrimental substances. Products that fulfil the criteria proposed help to minimise the impact of SSBs on the environment. Available assessment tools for dangerous substances (e.g. current legislation on environmental risk assessments and classification, and labelling, eco-labelling criteria for similar products, the calculation of the critical dilution volume) were adapted and integrated into the criteria for the eco-labelling of SSBs. A short outline of the eco-labelling criteria developed for SSBs is provided. The basic criteria concern the effects of the substances discharged into the waste water during and after use. Products with an eco-label award may exclusively contain substances for which basic information about their effects on the environment is available. They may not contain persistent, bioaccumulating, toxic or ecotoxicological substances. In addition, the basic criteria include requirements for the container and consumer information. The basic criteria for eco-labelling SSBs are based on the actual state of science and are at the same time as simple and transparent as possible to ensure the best applicability. SSBs that comply with the described basic criteria can contribute to a lower chemical burden of waste water treatment plants and surface water. The proposal for basic criteria described should stimulate discussion on eco-labelling of SSBs. It should help to pass

SOFT: smooth OPC fixing technique for ECO process

Zhang, Hongbo; Shi, Zheng

2007-03-01

SOFT (Smooth OPC Fixing Technique) is a new OPC flow developed from the basic OPC framework. It provides a new method to reduce the computation cost and complexities of ECO-OPC (Engineering Change Order - Optical Proximity Correction). In this paper, we introduce polygon comparison to extract the necessary but possibly lost fragmentation and offset information of previous post-OPC layout. By reusing these data, we can start the modification on each segment from a more accurate initial offset. In addition, the fragmentation method in the boundary of the patch in the previous OPC process is therefore available for engineers to stitch the regional ECO-OPC result back to the whole post-OPC layout seamlessly. For the ripple effect in the OPC, by comparing each segment's movement in each loop, we much free the fixing speed from the limitation of patch size. We handle layout remodification, especially in three basic kinds of ECO-OPC processes, while maintaining other design closure. Our experimental results show that, by utilizing the previous post-OPC layout, full-chip ECO-OPC can realize an over 5X acceleration and the regional ECO-OPC result can also be stitched back into the whole layout seamlessly with the ripple effect of the lithography interaction.

O fundamento estrutural do pensamento de Umberto Eco

Full Text Available Uma análise detalhada apresenta o método argumentativo a contrario, característico do artigo "Existe a contracultura?", de Umberto Eco, como paradigmático do princípio estruturalista da constituição do sentido por meio de oposições semânticas. O artigo argumenta que muitos dos escritos de Eco podem ser lidos como aplicações do princípio estruturalista de que apenas diferenças ou oposições carregam significação. A evidência do modo como o pensamento de Eco está sob o encanto do princípio das oposições e da dialética da presença e da ausência é apresentada através do levantamento dos escritos gerais de Eco e também da inspeção das obras A estrutura ausente e Semiótica e filosofia da linguagem. Além disso, o artigo revela que o pensamento de Eco é igualmente atraído tanto por processos nos quais oposições anulam ou dissolvem a si próprias quanto pela crítica pós-estruturalista do pensamento estruturalista.

Green Eco-Driving Effects in Non-Congested Cities

2017-12-01

Full Text Available Despite technological advances in engines and fuels, the transportation sector is still one of the largest emitters of greenhouse gas (GHG. Driving patterns, including eco-driving techniques, are a complementary measure for saving GHG emissions. Most eco-driving studies so far have been conducted in large cities suffering chronic congestion problems. The aim of this research is therefore to analyse the potential of driver behaviour for reducing emissions in a small non-congested city. Driver performance parameters such as travel speeds, number of stops, revolutions per minute, and maximum acceleration-deceleration are also studied. The methodology is designed to measure the effect of both eco-driving and eco-routing under real traffic conditions. A campaign was carried out in the city of Caceres (Spain to collect data on various types of roads under different traffic conditions. This research concludes that eco-driving leads to CO2 savings on all routes and road types of 17% in gasoline engines and 21% in diesel, although travel times are increased by 7.5% on average. The shortest route is also the most ecological, regardless of the traffic volume and characteristics, implying that consumption in non-congested cities depends mainly on distance travelled rather than driving patterns in terms of number of stops, speed and acceleration.

Designed especially for forest ecosystem studies, EcoSAR employs state-of-the-art digital beamforming technology to generate wide-swath, high-resolution imagery. EcoSARs dual antenna single-pass imaging capability eliminates temporal decorrelation from polarimetric and interferometric analysis, increasing the signal strength and simplifying models used to invert forest structure parameters. Antennae are physically separated by 25 meters providing single pass interferometry. In this mode the radar is most sensitive to topography. With 32 active transmit and receive channels, EcoSARs digital beamforming is an order of magnitude more versatile than the digital beamforming employed on the upcoming NISAR mission. EcoSARs long wavelength (P-band, 435 MHz, 69 cm) measurements can be used to simulate data products for ESAs future BIOMASS mission, allowing scientists to develop algorithms before the launch of the satellite. EcoSAR can also be deployed to collect much needed data where BIOMASS satellite wont be allowed to collect data (North America, Europe and Arctic), filling in the gaps to keep a watchful eye on the global carbon cycle. EcoSAR can play a vital role in monitoring, reporting and verification schemes of internationals programs such as UN-REDD (United Nations Reducing Emissions from Deforestation and Degradation) benefiting global society. EcoSAR was developed and flown with support from NASA Earth Sciences Technology Offices Instrument Incubator Program.

Full Text Available Climate change adaptation and mitigation have become key policy drivers in the UK under its Climate Change Act of 2008. At the same time, urbanization has been high on the agenda, given the pressing need for substantial additional housing, particularly in southeast England. These twin policy objectives were brought together in the UK government's 'eco-town' initiative for England launched in 2007, which has since resulted in four eco-town projects currently under development. We critically analyze the eco-town initiative's policy evolution and early planning phase from a multilevel governance perspective by focusing on the following two interrelated aspects: (1 the evolving governance structures and resulting dynamics arising from the development of the eco-town initiative at UK governmental level, and the subsequent partial devolution to local stakeholders, including local authorities and nongovernmental actors, under the new 'localism' agenda; and (2 the effect of these governance dynamics on the conceptual and practical approach to adaptation through the emerging eco-town projects. As such, we problematize the impact of multilevel governance relations, and competing governance strategies and leadership, on shaping eco-town and related adaptation strategies and practice.

To investigate the implementation of eco-friendly dental office strategies by Jordanian dentists. Self-designed questionnaires were provided to 150 dentists working in private dental practices in the city of Amman, the capital of Jordan. Dentists' names and addresses were obtained from the Jordanian Dental Association. Overall, the level of knowledge about eco-friendly dental offices strategies was high for amalgam, radiology, paper waste, infection control and energy and water conservation. In terms of implementation, the majority of Jordanian dentists apply few eco-friendly dental offices strategies. The most frequently identified barriers to implementation of eco-friendly dental offices strategies were cost and lack of incentives from the government. Most Jordanian dental practices are not eco-friendly. A continued focus on the impact of dental practices on the environment is needed through formal and continuing dental education. Results of this study can guide policy development to encourage implementation of eco-friendly strategies. © 2013 FDI World Dental Federation.

The demand to preserve the environment and form a sustainable development is greatly increasing in the recent decades all over the world, and this environmental concern is also merged in electrical power industry, resulting in many eco-design approaches in Transmission and Distribution (T and D) industries. As a method of eco-design, Life Cycle Assessment (LCA) is a systematic tool that enables the assessment of the environmental impacts of a product or service throughout its entire life cycle, i.e. raw material production, manufacture, distribution, use and disposal including all intervening transportation steps necessary or caused by the product's existence. In T and D industries, LCA has been done for a lot of products individually, in order to see one product's environmental impacts and to seek for ways of improving its environmental performance. This eco-design for product approach is a rather well-developed trend, however, as only a single electrical product cannot provide the electrical power to users, electrical system consists of a huge number of components, in order to investigate system's environmental profile, the entire environmental profiles of different composing products has to be integrated systematically, that is to say, a system approach is needed. Under this philosophy, the study 'Eco-design of Power Transmission Systems' is conducted in this thesis, with the purpose of analysing the transmission systems' environmental impacts, locating the major environmental burden sources of transmission systems, selecting and/or developing methodologies of reducing its environmental impacts.

FoldEco: A Model for Proteostasis in E. coli

Directory of Open Access Journals (Sweden)

Evan T. Powers

2012-03-01

Full Text Available To gain insight into the interplay of processes and species that maintain a correctly folded, functional proteome, we have developed a computational model called FoldEco. FoldEco models the cellular proteostasis network of the E. coli cytoplasm, including protein synthesis, degradation, aggregation, chaperone systems, and the folding characteristics of protein clients. We focused on E. coli because much of the needed input information—including mechanisms, rate parameters, and equilibrium coefficients—is available, largely from in vitro experiments; however, FoldEco will shed light on proteostasis in other organisms. FoldEco can generate hypotheses to guide the design of new experiments. Hypothesis generation leads to system-wide questions and shows how to convert these questions to experimentally measurable quantities, such as changes in protein concentrations with chaperone or protease levels, which can then be used to improve our current understanding of proteostasis and refine the model. A web version of FoldEco is available at http://foldeco.scripps.edu.

Consumer Acceptance of Eco-Labeled Fish: A Mexican Case Study

Directory of Open Access Journals (Sweden)

Mónica Pérez-Ramírez

2015-04-01

Full Text Available Fish eco-labeling is a market-based incentive program for sustainable fisheries. This paper examines consumers’ acceptance of eco-labeled fish by using data from a pilot study conducted in a coastal area of northwestern Mexico. An ordered probit model was applied, using 364 observations. The results show that most respondents favor the idea of eco-labeled fish as a sustainable option and know that this is a costlier option. Income level, consumers’ occupation and frequency of fish consumption are factors taken into account in the buying decision. Price was not a statistically significant factor affecting purchase decision. The study suggests that employed consumers with knowledge of labels may prioritize their demand for eco-labeled fish. Thus, providing a clear definition of sustainability that increases consumer awareness might be a promising strategy in developing the market for eco-labeled fish. The results and their implications could be employed as an element for future development of consumer policies related to fish sustainability.

Singh, Nitin Kumar; Singh, Rana Pratap; Kazmi, Absar Ahmad

2017-05-01

In the present study, a life cycle assessment (LCA) approach was used to analyse the environmental impacts associated with the construction and operational phases of an integrated fixed-film activated sludge (IFAS) reactor treating municipal wastewater. This study was conducted within the boundaries of a research project that aimed to investigate the implementation related challenges of a package type IFAS reactor from an environmental perspective. Along with the LCA results of the construction phase, a comparison of the LCA results of seven operational phases is also presented in this study. The results showed that among all the inputs, the use of stainless steel in the construction phase caused the highest impact on environment, followed by electricity consumption in raw materials production. The impact of the construction phase on toxicity impact indicators was found to be significant compared to all operational phases. Among the seven operational phases of this study, the dissolved oxygen phase III, having a concentration of ∼4.5 mg/L, showed the highest impact on abiotic depletion, acidification, global warming, ozone layer depletion, human toxicity, fresh water eco-toxicity, marine aquatic eco-toxicity, terrestrial eco-toxicity, and photochemical oxidation. However, better effluent quality in this phase reduced the eutrophication load on environment.

Conference logo The 21st century has been called the century of environmental revolution. Green innovations and environmentally friendly production systems based on physics, chemistry, materials science, and electronic engineering will be indispensable for ensuring renewable energy and establishing a sustainable society. In particular, production design, materials processing, and fabrication technologies such as welding and joining will be very important components of such green innovations. For these reasons, the International Symposium on Materials Science and Innovation for Sustainable Society - eco-materials and eco-innovation for global sustainability - (ECO-MATES 2011) was organized by the Joining and Welding Research Institute (JWRI) and the Center of Environmental Innovation Design for Sustainability (CEIDS), Osaka University. ECO-MATES 2011 was held at Hotel Hankyu Expo Park, Osaka, Japan from 28-30 November 2011. 435 participants from 20 countries around the world attended the symposium. 149 oral presentations including 60 invited talks and 160 posters were presented at the symposium to discuss the latest research and developments in green innovations in relation to environmental issues. The topics of the symposium covered all environmentally related fields including renewable energy, energy-materials, environment and resources, waste and biomass, power electronics, semiconductor, rare-earth metals, functional materials, organic electronics materials, electronics packaging, smart processing, joining and welding, eco-efficient processes, and green applied physics and chemistry. Therefore, 55 full papers concerning green innovations and environmentally benign production were selected and approved by the editorial board and the program committee of ECO-MATES 2011. All papers were accepted through peer review processes. I believe that all the papers have many informative contents. On behalf of the steering committee of the symposium, I would like to express

2007-11-01

Based on the data of land use/cover and by using eco-economic harmony index (EEH) this paper studied the spatiotemporal characteristics of ecosystem service value on the northern slope of Tianshan Mountains, and evaluated the harmony degree of eco-economic development in the region. The results showed that the total ecosystem service value on the northern slope of Tianshan Mountains was increased from 319.93 x 10(8) yuan in 1989 to 321.26 x 10(8) yuan in 2000, with a net increment of 0.42%. The regional eco-economic development was overall at a low harmony level, being higher in eastern part than in middle and western parts, among which, eight counties had a positive value of EEH and their eco-economic development was harmonious, while seven counties had a negative value of EEH and their eco-economic development was inharmonic. The eco-economic development in the region was at the margin of harmony, and thus, more attention should be paid to strengthen the protection of eco-environment and promote the harmonious development of eco-economy to have a sustainable development.

This paper first applied material flow analysis (MFA) to construct three levels of regional eco-efficiency indicators, i.e., regional direct eco-efficiency (RDE), regional total eco-efficiency (RTE), and holistic eco-efficiency (HE), and adopted the newly developed data envelopment analysis (DEA) to evaluate the eco-efficiency of Tongling City during the period of 1990-2008. We also applied Malmquist productivity index (MPI) to explore the eco-efficiency change between two following years and its driving factors. The main results were summarized as 1) though the RDE of Tongling City in 1990-2008 kept an increasing trend, its mean eco-efficiency was not high (close to 0.8 in 80% of the years), being lower than that of the RTE and HE, and 2) the RDE change was closely relevant to the improvement in resource management and the technical input in environmental protection in recent years. In order to further improve the RDE of the City, it would be necessary to raise its eco-efficiency via expanding raw material input, reducing domestic extraction, promoting resources productivity, and taking more measures on environmental protection facilities construction.

There is wide variation in clinical practice regarding the role of electrocorticography immediately after resection (post-resection ECoG) for pediatric epilepsy surgery. Results can guide further resection of potentially epileptogenic tissue. We hypothesized that post-resection ECoG spiking represents a biomarker of the epileptogenic zone and predicts seizure outcome in children undergoing epilepsy surgery. We retrospectively identified 124 children with post-resection ECoG performed on the margins of resection. ECoG records were scored in a blinded fashion based on presence of frequent spiking. For patients identified as having additional resection based on clinical post-resection ECoG interpretation, these "second-look" ECoG results were re-reviewed for ongoing discharges or completeness of resection. Frequent spike populations were grouped using a standard scoring system into three ranges: 0.1-0.5Hz, 0.5-1Hz, >1Hz. Seizure outcomes were determined at minimum 12-month followup. Of 124 patients who met inclusion criteria, 60 (48%) had an identified spike population on post-resection ECoG. Thirty (50%) of these had further resection based on clinical interpretation. Overall, good outcome (ILAE 1) was seen in 56/124 (45%). Completeness of resection of spiking (absence of spiking on initial post-resection ECoG or resolution of spiking after further resection) showed a trend toward good outcome (OR 2.03, p=0.099). Patients with completeness of resection had good outcome in 41/80 (51%) of cases; patients with continued spikes had good outcome in 15/44 (35%) of cases. Post-resection ECoG identifies residual epileptogenic tissue in a significant number of children. Lower frequency or absence of discharges on initial recording showed a trend toward good outcome. Completeness of resection demonstrated on final ECoG recording did not show a significant difference in outcome. This suggests that post-resection discharges represent a prognostic marker rather than a remediable

The use of fossil energy is one of the major environmental problems associated with tourism and travel. Consequently, the need to limit fossil energy use has been highlighted as a precondition for achieving sustainable tourism development. However, tourism is also one of the most important sectors of the world economy, and fears have thus been expressed by the tourist industry and its organisations that increasing energy prices (for example, as a result of eco-taxes) could substantially decrease the economic welfare of countries and destinations. In this article, the interplay of environmental damage and economic gains is thus analysed within the context of tourism. Carbon dioxide-equivalent emissions are assessed in relation to the revenues generated, allowing for conclusions about the eco-efficiency of tourism.

Supplying water to the ecological environment with certain quantity and quality is significant for the protection of diversity and the realization of sustainable development. The conception and connotation of eco-environmental water requirements, including the definition of the conception, the composition and characteristics of eco-environmental water requirements, are evaluated in this paper. The classification and estimation methods of eco-environmental water requirements are then proposed. On the basis of the study on the Huang-Huai-Hai Area, the present water use, the minimum and suitable water requirement are estimated and the corresponding water shortage is also calculated. According to the interrelated programs, the eco-environmental water requirements in the coming years (2010, 2030, 2050) are estimated. The result indicates that the minimum and suitable eco-environmental water requirements fluctuate with the differences of function setting and the referential standard of water resources, and so as the water shortage. Moreover, the study indicates that the minimum eco-environmental water requirement of the study area ranges from 2.84×1010m3 to 1.02×1011m3, the suitable water requirement ranges from 6.45×1010m3 to 1.78×1011m3, the water shortage ranges from 9.1×109m3 to 2.16×1010m3 under the minimum water requirement, and it is from 3.07×1010m3 to 7.53×1010m3 under the suitable water requirement. According to the different values of the water shortage, the water priority can be allocated. The ranges of the eco-environmental water requirements in the three coming years (2010, 2030, 2050) are 4.49×1010m3-1.73×1011m3, 5.99×10m3?2.09×1011m3, and 7.44×1010m3-2.52×1011m3, respectively.

Eco-Dimensionality as a Religious Foundation for Sustainability

Directory of Open Access Journals (Sweden)

Susan Power Bratton

2018-03-01

Full Text Available Academics have critiqued the Abrahamic faiths, particularly Christianity, as inadequate to respond to today’s environmental dilemmas due to abstract theological qualities like the concept of a unified or transcendent God. Christianity and Islam are the earth’s most populous religions, however, and they are growing in the global south. A literature review finds that both indigenous and world religions develop strategies for environmental sustainability. Examples include: Amazonian fisheries, Islamic gardens, monastic forest management, Baptist LEED certified buildings, and Christian agrarian stewardship. These cases share a characteristic termed eco-dimensionality, defined as the integrative expression of environmental values, caretaking norms and sustainable practices in all aspects of religion, that recognizes and specifically adapts to keystone environmental processes and ecosystemic or geo-physical diversity. Religious eco-dimensionality incorporates: inventorying biota and ecosystems, recognizing environmental spatial and temporal dynamics at multiple scales, understanding communitarian and anti-communitarian human behaviors, structuring social networks, adopting sustainable technologies, and developing an integrative repertoire of religious symbols, aesthetic endeavors and ceremonies. Eco-dimensionality can evolve to address new issues. Negatively stereotyping faith traditions can inhibit constructive conversations concerning environmental issues and development of religious symbols and practices enhancing eco-dimensionality.

The eco-driving effect of electric vehicles compared to conventional gasoline vehicles

Full Text Available Eco-driving is attractive to the public, not only users of internal-combustion-engine vehicles (ICEVs including hybrid electric vehicles (HEVs but also users of electric vehicles (EVs have interest in eco-driving. In this context, a quantitative evaluation of eco-driving effect of EVs was conducted using a chassis dynamometer (C/D with an “eco-driving test mode.” This mode comprised four speed patterns selected from fifty-two real-world driving datasets collected during an eco-driving test-ride event. The four patterns had the same travel distance (5.2 km, but showed varying eco-driving achievement levels. Three ICEVs, one HEV and two EVs were tested using a C/D. Good linear relationships were found between the eco-driving achievement level and electric or fuel consumption rate of all vehicles. The reduction of CO2 emissions was also estimated. The CO2-reduction rates of the four conventional (including hybrid vehicles were 10.9%–12.6%, while those of two types of EVs were 11.7%–18.4%. These results indicate that the eco-driving tips for conventional vehicles are effective to not only ICEVs and HEVs but also EVs. Furthermore, EVs have a higher potential of eco-driving effect than ICEVs and HEVs if EVs could maintain high energy conversion efficiency at low load range. This study is intended to support the importance of the dissemination of tools like the intelligent speed adaptation (ISA to obey the regulation speed in real time. In the future, also in the development and dissemination of automated driving systems, the viewpoint of achieving the traveling purpose with less kinetic energy would be important.

Forest Ecosystem Services and Eco-Compensation Mechanisms in China

2011-12-01

Forests are a major terrestrial ecosystem providing multiple ecosystem services. However, the importance of forests is frequently underestimated from an economic perspective because of the externalities and public good properties of these services. Forest eco-compensation is a transfer mechanism that serves to internalize the externalities of forest ecosystem services by compensating individuals or companies for the losses or costs resulting from the provision of these services. China's current forest eco-compensation system is centered mainly on noncommercial forest. The primary measures associated with ecosystem services are (1) a charge on destructive activities, such as indiscriminate logging, and (2) compensation for individual or local activities and investments in forest conservation. The Compensation Fund System for Forest Ecological Benefits was first listed in the Forest Law of the People's Republic of China in 1998. In 2004, the Central Government Financial Compensation Fund, an important source for the Compensation Fund for Forest Ecological Benefits, was formally established. To improve the forest eco-compensation system, it is crucial to design and establish compensation criteria for noncommercial forests. These criteria should take both theoretical and practical concerns into account, and they should be based on the quantitative valuation of ecosystem services. Although some initial headway has been made on this task, the implementation of an effective forest eco-compensation system in China still has deficiencies and still faces problems. Implementing classification-based and dynamic management for key noncommercial forests and establishing an eco-compensation mechanism with multiple funding sources in the market economy are the key measures needed to conquer these problems and improve the forest eco-compensation system and China's forestry development in sequence.

A distributed eco-hydrological model and its application

Zong-xue Xu

2017-10-01

Full Text Available Eco-hydrological processes in arid areas are the focus of many hydrological and water resources studies. However, the hydrological cycle and the ecological system have usually been considered separately in most previous studies, and the correlation between the two has not been fully understood. Interdisciplinary research on eco-hydrological processes using multidisciplinary knowledge has been insufficient. In order to quantitatively analyze and evaluate the interaction between the ecosystem and the hydrological cycle, a new kind of eco-hydrological model, the ecology module for a grid-based integrated surface and groundwater model (Eco-GISMOD, is proposed with a two-way coupling approach, which combines the ecological model (EPIC and hydrological model (GISMOD by considering water exchange in the soil layer. Water interaction between different soil layers is simply described through a generalized physical process in various situations. A special method was used to simulate the water exchange between plants and the soil layer, taking into account precipitation, evapotranspiration, infiltration, soil water replenishment, and root water uptake. In order to evaluate the system performance, the Heihe River Basin in northwestern China was selected for a case study. The results show that forests and crops were generally growing well with sufficient water supply, but water shortages, especially in the summer, inhibited the growth of grass and caused grass degradation. This demonstrates that water requirements and water consumption for different kinds of vegetation can be estimated by considering the water-supply rules of Eco-GISMOD, which will be helpful for the planning and management of water resources in the future.

Eco-cities as an Assemblage of Worlding Practices

Zack Lee

2015-09-01

Full Text Available Eco-cities are gaining attention in policy and academic circles over the past few years. Yet they pose difficulties as objects of study since they have been diversely defined and implemented. This paper argues that eco-cities are better understood as an assemblage of worlding practices. Combining these two concepts foregoes the emphasis on the eco-city’s physical structures and focuses more on its policy environment and its relations with other locations. The case study being examined is the Philippine’s Clark Green, the country’s first eco-city project. Its main proponent is an independent government agency, the Bases Conversion and Development Authority (BCDA, tasked with developing former military locations for civilian uses. Their vision is to create a world-class project built by international stakeholders in order to elevate the status of the Philippines and the Filipinos. They have chosen to emulate the Songdo International Business District in South Korea as their benchmark model. Not only are they adopting the ideas of a smart city but also similar strategies to enter the international education and logistics industries. The paper will show how the BCDA uses the eco-city idea as a tool to enter various national and international discourses that extend beyond the project’s geographical boundaries. Yet the strategies and visions of an independent government-owned corporation are tempered by challenges from local stakeholders, conflicting national priorities, and failures from similar policies applied elsewhere. The paper highlights the need for worlding projects to be embedded in their own national context for greater policy coordination.

Decoding Finger Flexion From Band-specific ECoG Signals in Humans

Nanying eLiang

2012-06-01

Full Text Available This article presents the method that won the BCI competition IV addressed to the pre- diction of the finger flexion from ECoG signals. ECoG-based BCIs have recently drawn the attention from the community. Indeed, ECoG can provide a higher spatial resolution, a higher signal quality and is more suitable for long-term use than classical EEG recordings. These characteristics allow to decode precise brain activities and to realize efficient ECoG-based neu- roprostheses. Signal processing is a very important task in BCIs research for translating brain signals into commands. Here, we present a linear regression method based on the amplitude modulation of band-specific ECoG including a short term memory for individual finger flexion prediction. The effectiveness of the method was proven by achieving the highest value of corre- lation coefficient between the predicted and recorded finger flexion values on data set 4 during the BCI competition IV.

Eco-ethology. Oeko-Ethologie

Krebs, J.R.; Davies, N.B.

1981-01-01

Eco-ethology is the science of the effects of animal behaviour on animal environment and the effects of animal environment on animal behaviour, with the purpose to find out how natural selection within this control loop has formed and molded animals. N. Tinbergen was the first to make experiments on the evolution of patterns of behaviour which are influenced not only by the evolution of species but also by their adaptation to a changing environment. R.H. MacArthur then introduced mathematical modelling for better clarification of the function and adoptive value of behavioural patterns. The book gives a detailed description of both methods and a successful attempt at a synthesis. In surveys and specific contribution, an exemplary outline of eco-ethology is presented, with information, ideas and reflections that are of interest both to teachers and students. The book is addressed to biologists, zoologists, ecologists, sociologists, and evolutionary biologists and to students of these disciplines.

Synthesis of Constructs for Modeling Consumers’ Understanding and Perception of Eco-Labels

Full Text Available The term “eco-labeling” has become a buzzword in today’s sustainable business world. The use of eco-labeling in various forms has been increasing notably for past many years, sometimes as an environmental “requirement” and sometimes merely as a marketing tool. Questions arise about how well these eco-labels are attended and understood by consumers. However, though mentionable studies are found on various aspects of eco-labels, gaps exist in exploring an inclusive set of parameters for investigating consumer perceptions of eco-labels. This paper aims at preparing a synthesis of all the possible factors to be incorporated for measuring consumer perceptions of eco-labeling of products. For making such synthesis, all major works in the field have been thoroughly reviewed. The paper comes up with a total of 10 parameters that include consumer awareness, consumer knowledge, consumer involvement, consumer trust, design and visibility, credibility of the source, type and level of information, clarity of meaning, persuasiveness, and private benefits. This tentative, yet inclusive, set of parameters is thought to be useful for designing large scale future empirical researches for developing a dependable inclusive set of parameters to test consumer understanding and perceptions of eco-label. A framework is proposed for further empirical research.

A Sustainability Model for Bringing Core Villages into Eco-tourism

2014-12-01

Full Text Available Eco villages comprise a part of eco-tourism in rural regions, and are the destination of choice for those who wish to experience a taste of traditional life. In 2004, through a series of by-laws, the Turkish Republic of Northern Cyprus (KKTC initiated an eco-tourism movement in the Karpaz Peninsula. It was envisioned then that a planning approach within the framework of sustainability would be of importance to the island, and the project was developed using a sustainable planning approach with a view to contributing to the state’s initiative to incorporate core villages into tourism on the island. Eco-tourism and the eco-village were explored within the framework of environmental problems, sustainable development and environmental sustainability, and the concept of core village was explained, with an emphasis on its benefits for tourism on the island. To ensure sustainability of the villages, a conceptual framework based on the principles of sustainable planning was established, specifically, in this case, on the Wheeler principles. These are grouped as: a. Compact, efficient land use, b. Less automobile use, better access, c. Efficient use of resources, reduction of pollution and waste, d. Restoration of natural systems, e. Good housing and living environments, f. Healthy social ecology, g. Sustainable economics, h. Community participation, i. Preservation of local culture and wisdom. These are used as cross references in assessing the situation in Büyükkonuk Village, the place nominated as the pilot area for eco-tourism.

Contemporary examples of zero-carbon cities: Masdar City, United Arab Emirates and Dongtan, China, confirm technical feasibility of renewable energy by implementation of solar PV and wind technologies. The ecological city - medium or high density urban settlement separated by greenspace causes the smallest possible ecological footprint on the surrounding countryside through efficient use of land and its resources, recycling used materials and converting waste to energy. This paper investigates the concept of energy sustainable cities, examines, how urban settlements might affect building energy design in eco-villages, eco-districts (e.g. Vauban, Freiburg in Germany, Bo01 Malmo in Sweden), and discuss the strategies for achieving Zero Emission Cities principles in densely populated areas. It is focused on low energy architectural design solutions which could be incorporated into urban settlements to create ecological villages, districts and cities, designed with consideration of environmental impact, required minimal inputs of energy, water, food, waste and pollution.

The study analyses the relationships between the main drivers of eco-innovation introduced by innovative industries, focused on cooperation strategy. Eco-innovation is analysed by means of a multidimensional identification strategy, showing the relationships between the independent variables and the variable of interest. The literature discussing environmental innovation is different from the one discussing other types of innovation inasmuch as it seeks to grasp its determinants and to mostly highlight the relevance of environmental regulation. The key feature of this paper is that it ascribes special relevance to cooperation strategy with external partners and to the propensity of innovative industry introducing eco-innovation. A sample of 35,060 Brazilian industries were analysed, between 2003 and 2011, by means of Binomial, Multinomial and Ordinal logistic regressions with microdata collected with the research and innovation department (PINTEC) from the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística). The econometric results estimated by the Logit Multinomial method suggest that the cooperation with external partners practiced by innovative industries facilitates the adoption of eco-innovation in dimension 01 with probability of 64.59%, 57.63% in dimension 02 and 81.02% in dimension 03. The data reveal that the higher the degree of eco-innovation complexity, the harder industries seek to obtain cooperation with external partners. When calculating with the Logit Ordinal and Binomial models, cooperation increases the probability that the industry is eco-innovative in 65.09% and 89.34%, respectively. Environmental regulation and innovation in product and information management were also positively correlated as drivers of eco-innovation.

Full Text Available Eco-environmental stress refers to the pressure borne by the environment in sustaining the pre-existing non-industrialized state and/or in counteracting adverse impacts caused by natural and human factors. The present article introduces the concept, research progress, and method for assessing eco-environmental stress. An eco-environmental stress index (ESI is established to assess the eco-environmental stress of 13 cities in the Western Taiwan Straits Economic Zone (hereafter referred to as the Economic Zone during the period from 2000 to 2010. The research provides a reference for the strategic planning of industrial development and environmental protection. The results show that the overall eco-environmental stress of the Economic Zone was slight and did not have significant change during the past 10 years. The cities with the most severe eco-environmental stress are distributed in the north and south of the Economic Zone. Most areas of Fujian Province have a low degree of eco-environmental stress, a situation that is being constantly improved. The regions with high atmospheric and water pollutant emissions are concentrated in the northern, middle, and southern coastal regions of the Economic Zone. The pollutant emissions of coastal cities are higher than those of inland cities. In the future, ecological restoration and compensation mechanisms should be established for regions where environmental protection and remediation is urgently needed.

ECO-DRIVING Europe - building the frame for a European market for eco-driving

Due to rapidly increasing greenhouse gas emissions, the transport sector is a key issue in any sustainability and climate strategy. Still, it is the one most difficult to deal with because of it's complexity and direct impact on everybody's life. Innovative transport technologies can significantly contribute to reducing emissions and energy use, but there is also a need for behavioural changes to turn down energy demand, especially in individual motorised transport. One of the most cost-effective measures in this field is Ecodriving, an energy efficient and road safety improving driving style. Nowadays, there are several stand-alone initiatives in Europe. But to strengthen Ecodriving and increase its market share it needs: - an overview of existing offers and facilities, - pilot projects with different target groups, - training courses (both for novice drivers and experienced road users), - quality standards, - scientific proof of the various benefits, - awareness raising and marketing. That's why ECO-DRIVING Europe has been initiated by the main stakeholders in Europe. It aims to change the behaviour of drivers by using technological developments, influencing legislation and supporting long term driving and mobility culture change. The Europe-wide ECO-DRIVING project (www.ecodrive.org ) tries to reach this goal by integrating Ecodriving into various policy fields such as energy, climate change, road safety, local environment, sustainable transport and legislation for driver licence procedures. By decreasing greenhouse gas emission by 10-20% compared to normal driving, Ecodriving can considerably contribute to reduce energy demand in transport and fight climate change.

Full Text Available Electrocorticography (ECoG has been demonstrated as a promising neural signal source for developing brain-machine interfaces (BMIs. However, many concerns about the disadvantages brought by large craniotomy for implanting the ECoG grid limit the clinical translation of ECoG-based BMIs. In this study, we collected clinical ECoG signals from the sensorimotor cortex of three epileptic participants when they performed hand gestures. The ECoG power spectrum in hybrid frequency bands was extracted to build a synchronous real-time BMI system. High decoding accuracy of the three gestures was achieved in both offline analysis (85.7%, 84.5%, and 69.7% and online tests (80% and 82%, tested on two participants only. We found that the decoding performance was maintained even with a subset of channels selected by a greedy algorithm. More importantly, these selected channels were mostly distributed along the central sulcus and clustered in the area of 3 interelectrode squares. Our findings of the reduced and clustered distribution of ECoG channels further supported the feasibility of clinically implementing the ECoG-based BMI system for the control of hand gestures.

Energy production and industrial processes are crucial economic sectors accounting for about 62% of greenhouse gas (GHG) emissions globally in 2012. Eco-industrial parks are practical attempts to mitigate GHG emissions through cooperation among businesses and the local community in order to reduce waste and pollution, efficiently share resources, and help with the pursuit of sustainable development. This work developed a framework based on ecological network analysis to trace carbon metabolic processes in eco-industrial parks and applied it to a typical eco-industrial park in Beijing. Our findings show that the entire metabolic system is dominated by supply of primary goods from the external environment and final demand. The more carbon flows through a sector, the more influence it would exert upon the whole system. External environment and energy providers are the most active and dominating part of the carbon metabolic system, which should be the first target to mitigate emissions by increasing efficiencies. The carbon metabolism of the eco-industrial park can be seen as an evolutionary system with high levels of efficiency, but this may come at the expense of larger levels of resilience. This work may provide a useful modeling framework for low-carbon design and management of industrial parks.

Full Text Available Ecological security and environmental sustainability are the foundations of sustainable development. With the acceleration of urbanization, increasing human activities have promoted greater impacts on the eco-spaces that maintain ecological security. Regional key eco-space has become the primary need to maintain environmental sustainability and can offer society with continued ecosystem services. In this paper, considering the security of water resources, biodiversity conservation, disaster avoidance and protection and natural recreation, an integrated index of eco-space importance was established and a method for identifying key eco-space was created using GIS, with Lanzhou City, China as a case study. The results show that the area of core eco-space in the Lanzhou City is approximately 50,908.7 hm2, accounting for 40% of the region’s total area. These areas mainly consist of geological hazard protection zones and the core zones of regional river systems, wetlands, nature reserves, forest parks and scenic spots. The results of this study provide some guidance for the management of ecological security, ecological restoration and environmental sustainability.

Mao, Hui-ping; He, Xuan; He, Jia; Niu, Dong-jie; Bao, Cun-kuan

2013-04-01

Ecological civilization is to normalize human development behaviors to harmonize the relationships between social and ecological development and eco-environment protection. In this paper, a comparative analysis was made on the ecological demonstration activities of ecological demonstration areas led by the Ministry of Environmental Protection, exemplar cities of national environmental protection, and ecological provinces, cities, and counties. It was considered that all the ecological demonstration activities had the problems of lacking pertinence of construction goals, disordered construction subjects, inefficient construction processes, and lacking continuous incentive mechanisms of assessment. In the meantime, through the analysis of the connotations of eco-civilization, the relationships between eco-civilization and eco-demonstration constructions were approached, and the eco-civilization construction mode was put forward in terms of construction goal, construction subject, and construction processes and assessment. The construction mode included the construction goal based on regional characteristics; the synergistic cooperation of construction subjects, the expanding ways of public participation, and the establishment of evaluation system for comprehensively measuring the 'actions and results'.

ECO DESIGN IN DESIGN PROCESS

Directory of Open Access Journals (Sweden)

PRALEA Jeni

2014-05-01

Full Text Available Eco-design is a new domain, required by the new trends and existing concerns worldwide, generated by the necessity of adopting new design principles. New design principles require the designer to provide a friendly relationship between concept created, environment and consume. This "friendly" relationship should be valid both at present and in the future, generating new opportunities for product, product components or materials from which it was made. Awareness, by the designer, the importance of this new trend, permits the establishment of concepts that have as their objective the protection of present values and ensuring the legacy of future generations. Ecodesig, by its principles, is involved in the design process, from early stage, the stage of product design. Priority objective of the designers will consist in reducing the negative effects on the environment through the entire life cycle and after it is taken out of use. The main aspects of the eco-design will consider extending product exploitation, make better use of materials, reduction of emission of waste. The design process in the "eco"domein must be started by selecting the function of the concept, materials and technological processes, causing the shape of macro and micro geometric of the product through an analysis that involves optimizing and streamlining the product. This paper presents the design process of a cross-sports footwear concept, built on the basis of the principles of ecodesign

Eco-genetic modeling of contemporary life-history evolution.

Dunlop, Erin S; Heino, Mikko; Dieckmann, Ulf

2009-10-01

We present eco-genetic modeling as a flexible tool for exploring the course and rates of multi-trait life-history evolution in natural populations. We build on existing modeling approaches by combining features that facilitate studying the ecological and evolutionary dynamics of realistically structured populations. In particular, the joint consideration of age and size structure enables the analysis of phenotypically plastic populations with more than a single growth trajectory, and ecological feedback is readily included in the form of density dependence and frequency dependence. Stochasticity and life-history trade-offs can also be implemented. Critically, eco-genetic models permit the incorporation of salient genetic detail such as a population's genetic variances and covariances and the corresponding heritabilities, as well as the probabilistic inheritance and phenotypic expression of quantitative traits. These inclusions are crucial for predicting rates of evolutionary change on both contemporary and longer timescales. An eco-genetic model can be tightly coupled with empirical data and therefore may have considerable practical relevance, in terms of generating testable predictions and evaluating alternative management measures. To illustrate the utility of these models, we present as an example an eco-genetic model used to study harvest-induced evolution of multiple traits in Atlantic cod. The predictions of our model (most notably that harvesting induces a genetic reduction in age and size at maturation, an increase or decrease in growth capacity depending on the minimum-length limit, and an increase in reproductive investment) are corroborated by patterns observed in wild populations. The predicted genetic changes occur together with plastic changes that could phenotypically mask the former. Importantly, our analysis predicts that evolutionary changes show little signs of reversal following a harvest moratorium. This illustrates how predictions offered by

Full Text Available The present study was created in order to customise the marketing mix for non-purchasers of eco-friendly products by studying their perspectives on the introduction of eco-friendly variants of the regular products that they are using in particular product categories (personal care and home care. Overall previous literature reviews in this area imply that there is a gap in the scientific literature on the marketing mix formulation for converting non-purchasers into purchasers of eco-friendly products to augment eco-friendly product sales and adopt green marketing. As literature reviews had clearly indicated that green purchasers have a very low percentage when compared to non-purchasers, the purpose is to create new opportunities for successful green marketing as the study tries to convert non-purchasers into purchasers. We used descriptive research design to study a sample of 885 respondents, who were surveyed in 2 cities in the Tamil Nadu state in India, to acquire an in-depth understanding of consumer behaviour that would enable the consumption of eco-friendly products among non-purchasers. The results reveal the marketing mix requirement and the eco-friendly aspects needed by the non-purchasers in order to buy the eco-friendly variants. The research sheds light on the product, price and promotion components that will attract non-purchases of eco-friendly products to buy eco-friendly products, thus facilitating green marketing mix adaptation. The study will provide valuable input for further research in formulating the marketing mix necessary to enable consumption of eco-friendly products in different geographical locations and various product categories.

A Product Line Analysis for Eco-Designed Fashion Products: Evidence from an Outdoor Sportswear Brand

Directory of Open Access Journals (Sweden)

Luo Wang

2017-07-01

Full Text Available With the increasing awareness of sustainability, eco-design has been an important trend in the fashion industry. Many fashion brands such as Nike, Adidas, and The North Face have developed sustainable fashion by incorporating eco-design elements. Eco-design is an important part of sustainable supply chains. In this paper, we conducted a product line analysis of eco-designed products from a famous outdoor sportswear brand, Patagonia. We collected Patagonia’s 2017 Spring Season product line data and analyzed the data through descriptive analysis, factor analysis and correlation analysis. We found that Patagonia mainly uses organic, recycled, and traceable materials in their eco-product line development. We identified that the usage of eco-materials may significantly affect the number of color choices and product weight as well as gender difference, pattern design, product fit and online reviewers’ opinions at Patagonia. We argued that Patagonia should focus on functionality more than aesthetics in eco-design. We discussed how sustainable fashion firms should manage eco-design in the supply chain.

Eco-evolutionary spatial dynamics in the Glanville fritillary butterfly.

Science.gov (United States)

Hanski, Ilkka A

2011-08-30

Demographic population dynamics, gene flow, and local adaptation may influence each other and lead to coupling of ecological and evolutionary dynamics, especially in species inhabiting fragmented heterogeneous environments. Here, I review long-term research on eco-evolutionary spatial dynamics in the Glanville fritillary butterfly inhabiting a large network of approximately 4,000 meadows in Finland. The metapopulation persists in a balance between frequent local extinctions and recolonizations. The genetic spatial structure as defined by neutral markers is much more coarse-grained than the demographic spatial structure determined by the fragmented habitat, yet small-scale spatial structure has important consequences for the dynamics. I discuss three examples of eco-evolutionary spatial dynamics. (i) Extinction-colonization metapopulation dynamics influence allele frequency changes in the phosphoglucose isomerase (Pgi) gene, which leads to strong associations between genetic variation in Pgi and dispersal, recolonization, and local population dynamics. (ii) Inbreeding in local populations increases their risk for extinction, whereas reciprocal effects between inbreeding, population size, and emigration represent likely eco-evolutionary feedbacks. (iii) Genetically determined female oviposition preference for two host plant species exhibits a cline paralleling a gradient in host plant relative abundances, and host plant preference of dispersing females in relation to the host plant composition of habitat patches influences immigration (gene flow) and recolonization (founder events). Eco-evolutionary spatial dynamics in heterogeneous environments may not lead to directional evolutionary changes unless the environment itself changes, but eco-evolutionary dynamics may contribute to the maintenance of genetic variation attributable to fluctuating selection in space and time.

Shang, Wenxiu; Gong, Yicheng; Wang, Zhongjing; Stewardson, Michael J

2018-03-15

Eco-compensation is the most important form of compensatory conservation in China. However, this compensatory mechanism is criticized for vague definition and massive government participation. For better understanding of eco-compensation in China, this paper compares theories and practices of compensatory mechanisms in China and abroad. The analysis of theoretical backgrounds shows that eco-compensation in China is a combination of 'ecological compensation' and 'payments for ecosystem services'. Ten compensatory projects in China and abroad are assessed to reveal characteristics and problems of eco-compensation in China. The results show that compensatory projects in China lagged behind mature foreign compensatory projects in clarity of property rights, responsibility fulfillment, executive efficiency, effectiveness, sustainability and equality. The massive participation of the government is the major reason for the poor performance of compensatory projects in China. However, government participation is necessary at the present stage in China for the income gap and beneficiaries' low willingness to pay. For the improvement of eco-compensation in China, suggestions are given on the choice of non-market valuation methods, the creation of property rights and the establishment of market mechanisms.

Urban planning solutions and decisions have large-scale significance for ecological sustainability (eco-efficiency) the consumption of energy and other natural resources, the production of greenhouse gas and other emissions and the costs caused by urban form. Climate change brings new and growing challenges for urban planning. The EcoBalance model was developed to assess the sustainability of urban form and has been applied at various planning levels: regional plans, local master plans and detailed plans. The EcoBalance model estimates the total consumption of energy and other natural resources, the production of emissions and wastes and the costs caused directly and indirectly by urban form on a life cycle basis. The results of the case studies provide information about the ecological impacts of various solutions in urban development. (orig.)

Xie, Hualin; Wang, Peng; Huang, Hongsheng

2013-01-01

Land use/land cover change has been attracting increasing attention in the field of global environmental change research because of its role in the social and ecological environment. To explore the ecological risk characteristics of land use change in the Poyang Lake Eco-economic Zone of China, an eco-risk index was established in this study by the combination of a landscape disturbance index with a landscape fragmentation index. Spatial distribution and gradient difference of land use eco-risk are analyzed by using the methods of spatial autocorrelation and semivariance. Results show that ecological risk in the study area has a positive correlation, and there is a decreasing trend with the increase of grain size both in 1995 and 2005. Because the area of high eco-risk value increased from 1995 to 2005, eco-environment quality declined slightly in the study area. There are distinct spatial changes in the concentrated areas with high land use eco-risk values from 1995 to 2005. The step length of spatial separation of land use eco-risk is comparatively long—58 km in 1995 and 11 km in 2005—respectively. There are still nonstructural factors affecting the quality of the regional ecological environment at some small-scales. Our research results can provide some useful information for land eco-management, eco-environmental harnessing and restoration. In the future, some measures should be put forward in the regions with high eco-risk value, which include strengthening land use management, avoiding unreasonable types of land use and reducing the degree of fragmentation and separation.

Full Text Available The present paper investigates the impact of pollution information transparency index (PITI on eco-efficiency using a novel panel dataset covering 109 key environmental protection prefecture-level cities in China over the period 2008–2015. We apply an extended data envelopment analysis (DEA model, simultaneously incorporating metafrontier, undesirable outputs and super efficiency into slack-based measure (Meta-US-SBM to estimate eco-efficiency. Then, the bootstrap Granger causality approach is utilized to test the unidirectional Granger causal relationship running from PITI to eco-efficiency. Results of DEA model show that there exist significant spatiotemporal disparities of eco-efficiency, on average, the eco-efficiency in eastern region is relative higher than those of central/western region. Estimates of ordinary least square (OLS method, quantile regression, and spatial Durbin model document that the evidence of an inverted-U-shaped relation between PITI and eco-efficiency is supported, and the turning points vary from 0.3370 to 0.4540 with different model specifications. Finally, supplementary analysis of panel threshold model also supports the robust findings. Policy implications are presented based on the empirical results.

Sustainability analysis requires a joint assessment of environmental, social and economic aspects of production processes. Here we propose the use of Life Cycle Analysis (LCA), a metafrontier (MF) directional distance function (DDF) approach, and Data Envelopment Analysis (DEA), to assess technological and managerial differences in eco-efficiency between production systems. We use LCA to compute six environmental and health impacts associated with the production processes of nearly 200 Spanish citrus farms belonging to organic and conventional farming systems. DEA is then employed to obtain joint economic-environmental farm's scores that we refer to as eco-efficiency. DDF allows us to determine farms' global eco-efficiency scores, as well as eco-efficiency scores with respect to specific environmental impacts. Furthermore, the use of an MF helps us to disentangle technological and managerial eco-inefficiencies by comparing the eco-efficiency of both farming systems with regards to a common benchmark. Our core results suggest that the shift from conventional to organic farming technology would allow a potential reduction in environmental impacts of 80% without resulting in any decline in economic performance. In contrast, as regards farmers' managerial capacities, both systems display quite similar mean scores.

Dengue is considered one of the most important vector-borne diseases in Thailand. Its incidence is increasing despite routine implementation of national dengue control programmes. This study, conducted during 2010, aimed to demonstrate an application of integrated, community-based, eco-bio-social strategies in combination with locally-produced eco-friendly vector control tools in the dengue control programme, emphasizing urban and peri-urban settings in eastern Thailand. Three different community settings were selected and were randomly assigned to intervention and control clusters. Key community leaders and relevant governmental authorities were approached to participate in this intervention programme. Ecohealth volunteers were identified and trained in each study community. They were selected among active community health volunteers and were trained by public health experts to conduct vector control activities in their own communities using environmental management in combination with eco-friendly vector control tools. These trained ecohealth volunteers carried out outreach health education and vector control during household visits. Management of public spaces and public properties, especially solid waste management, was efficiently carried out by local municipalities. Significant reduction in the pupae per person index in the intervention clusters when compared to the control ones was used as a proxy to determine the impact of this programme. Our community-based dengue vector control programme demonstrated a significant reduction in the pupae per person index during entomological surveys which were conducted at two-month intervals from May 2010 for the total of six months in the intervention and control clusters. The programme also raised awareness in applying eco-friendly vector control approaches and increased intersectoral and household participation in dengue control activities.

Life without chemicals would be inconceivable, but the potential risks and impacts to the environment associated with chemical production and chemical products are viewed critically. Eco-efficiency analysis considers the economic and life cycle environmental effects of a product or process, giving these equal weighting. The major elements of the environmental assessment include primary energy use, raw materials utilization, emissions to all media, toxicity, safety risk, and land use. The relevance of each environmental category and also for the economic versus the environmental impacts is evaluated using national emissions and economic data. The eco-efficiency analysis method of BASF is briefly presented, and results from three applications to chemical processes and products are summarized. Through these applications, the eco-efficiency analyses mostly confirm the 12 Principles listed in Anastas and Zimmerman (Environ. Sci. Technol. 2003, 37(5), 94A), with the exception that, in one application, production systems based on bio-based feedstocks were not the most eco-efficient as compared to those based on fossil resources. Over 180 eco-efficiency analyses have been conducted at BASF, and their results have been used to support strategic decision-making, marketing, research and development, and communication with external parties. Eco-efficiency analysis, as one important strategy and success factor in sustainable development, will continue to be a very strong operational tool at BASF.

Environmental performance indicators (EPI) were discussed and a method by which companies can design indicators to help measure their progress toward greater eco-efficiency was presented. EPIs are quantitative measures of environmental performance. EPIs can measure one attribute, such as effluent released to water, or they can be a complex index. EPIs track impacts on the environment and provide information for decision making. The need for more eco-efficient companies, i.e. companies that produce useful goods and services while reducing their consumption of resources and while making efforts to reduce pollution, was emphasized

Can Consumers Understand Sustainability through Seafood Eco-Labels? A U.S. and UK Case Study

Directory of Open Access Journals (Sweden)

Alexis Gutierrez

2014-11-01

Full Text Available In the United States and the United Kingdom, over the last decade major retail chains have increasingly publicized their efforts to supply sustainably sourced and eco-labelled seafood. Debate exists over the extent of consumer demand for this product. Seafood eco-labels purportedly resolve the information asymmetry between producer and consumer, allowing consumers who care about sustainability to easily find and purchase these products. This paper discusses the idealized model of seafood eco-labelling in promoting sustainability and presents results of US and UK case studies based on consumer interviews and surveys, which found that consumers had often seen one or more seafood eco-labels. Two well-established eco-labels, dolphin-safe and organic, drove these rates of sustainable seafood awareness. These rates are interpreted in the context of consumer’s understanding of sustainable. The Sustainable Seafood Movement’s efforts to increase the supply of eco-labelled seafood and elaborate corporate buying policies for sustainable seafood are influencing consumer’s recognition and purchase of certified sustainable seafood products. However, eco-labels are a means to communicate messages about sustainable fisheries to consumers, not an end. Efforts to educate consumers about eco-labels should be a component of ocean literacy efforts, which educate the public about the need for sustainable fisheries.

Nakata, K; Kawamura, H

1986-01-01

In rats with a high mesencephalic transection, isolating both the locus coeruleus and raphe nuclei from the forebrain, Electrocorticogram (ECoG) and Electromyogram (EMG) of the neck muscles were continuously recorded. Normal sleep-waking ECoG changes with a significant circadian rhythm reappeared in 4 to 9 days after transection. Neck muscle EMG and bodily movements were independent of the ECoG changes and did not show any significant circadian rhythm. In these high mesencephalic rats with sleep-waking ECoG changes, large bilateral hypothalamic lesions were made by passing DC current either in the preoptic area or in the posterior hypothalamus. After the preoptic area lesions the amount of low voltage fast ECoG per day markedly increased, whereas after the posterior hypothalamic lesions, the total amount of low voltate fast wave per day decreased showing long-lasting slow wave sleep pattern. These results support an idea that the forebrain, especially in the hypothalamus including the preoptic area, a mechanism inducing sleep-waking ECoG changes is localized.

Eco-evolutionary dynamics have been shown to be important for understanding population and community stability and their adaptive potential. However, coevolution in the framework of eco-evolutionary theory has not been addressed directly. Combining experiments with an algal host and its viral parasite, and mathematical model analyses we show eco-evolutionary dynamics in antagonistic coevolving populations. The interaction between antagonists initially resulted in arms race dynamics (ARD) with selective sweeps, causing oscillating host-virus population dynamics. However, ARD ended and populations stabilised after the evolution of a general resistant host, whereas a trade-off between host resistance and growth then maintained host diversity over time (trade-off driven dynamics). Most importantly, our study shows that the interaction between ecology and evolution had important consequences for the predictability of the mode and tempo of adaptive change and for the stability and adaptive potential of populations. © 2016 John Wiley & Sons Ltd/CNRS.

Highlights: • We examined occupants’ responses to an eco-feedback system in a commercial building. • We analyzed the impact of notifications on the level of engagement of participants. • We found notification effectiveness to be highly dependent on the type of feedback. • Occupant response to uniform normative comparison eco-feedback varied substantially. • This highlights the need for targeted eco-feedback based on consumption patterns. - Abstract: Despite all improvements in buildings shell, equipment, and design, CO_2 emissions from buildings are increasing. Since occupants spend more than 87% of their time indoors, they are inseparable and significant elements of building system dynamics. Hence, there is a great potential for energy efficiency in buildings using a wide range of programs such as intervention and eco-feedback. Despite the high level of individual differences and intra-class variability of occupants’ behaviors, the current state-of-the-art eco-feedback programs treat all the occupants uniformly and do not target and tailor the feedback. Therefore, it leaves an opportunity to increase the efficacy of eco-feedback systems through the designing of tailored and targeted programs. In this paper, we conducted a comprehensive analysis and tested hypotheses on occupants’ behavioral responses to a normative comparison feedback program, in addition to the impact of notifications on the level of engagement of each group of occupants. We categorized occupants who participated in the normative comparison feedback program into three groups (i.e. low, medium, and high energy consumers) based on their baseline energy consumption, and tested 9 hypotheses. A mixed-effect regression model (MRM) and a paired t-test was implemented to evaluate the proposed hypotheses. The hypotheses examine the variability of occupants’ responses under the same eco-feedback program, and the effectiveness of notifications on reinforcing occupants’ engagement in

Utilization of waste glass in ECO-cement: Strength properties and microstructural observations

2007-01-01

Waste glass creates a serious environmental problem, mainly because of the inconsistency of the waste glass streams. The use of waste glass as a finely ground mineral additive (FGMA) in cement is a promising direction for recycling. Based on the method of mechano-chemical activation, a new group of ECO-cements was developed. In ECO-cement, relatively large amounts (up to 70%) of portland cement clinker can be replaced with waste glass. This report examines the effect of waste glass on the microstructure and strength of ECO-cement based materials. Scanning electron microscopy (SEM) investigations were used to observe the changes in the cement hydrates and interface between the cement matrix and waste glass particles. According to the research results, the developed ECO-cement with 50% of waste glass possessed compressive strength properties at a level similar to normal portland cement

Eco-Efficiency Indicators for Urban Transport

Directory of Open Access Journals (Sweden)

Patrick Moriarty

2015-06-01

Full Text Available This paper focuses on urban passenger transport eco-efficiency, which can be defined as the production of maximum benefits to society while minimising environmental impacts from urban transport’s inputs of energy and materials. Researchers have intensively studied transport’s varied environmental impacts, particularly through Life Cycle Assessment; this paper argues that primary transport energy per capita is presently the best measure of impact. Although transport’s societal benefits have generally been regarded as self-evident, access to out-of-home activities, not passenger-km, should be considered as the fundamental useful output of an urban transport system, since transport is a derived demand. We argue that access levels are roughly similar in all high-income OECD cities, so that these cities can be ranked on transport eco-efficiency simply on the basis of per capita primary transport energy.

This article takes a look at how the Swiss Raetia-Energie group markets ecologically produced power. As opposed to physically delivering the electricity to its eco-customers, Raetia Energie sells certificates for the production of this form of clean power. The price of the certificates reflects the difference between the higher price for the eco-electricity and normal, non-certified power. The article discusses this mechanism, which is successfully used for customers in Switzerland and Germany. Part of the earnings made from the 'Naturemade Star' certified electricity is used to finance ecological projects in the company's area, famous for its tourist attractions

Umberto Eco: Freedom and the limits of artwork interpretation

Directory of Open Access Journals (Sweden)

Kršić Lamija

2017-01-01

Full Text Available In his study The Open Work (1962 Umberto Eco commenced his long term exploration of the nature of interpreting an artwork. The author problematizes the question of freedom and the limits of artwork interpretation in the context of semiology and theory of semiotics. Although the contemporary debates on interpreting art focus on interpretation and interpreter, that is to say, on unconditional openness of the work, Eco reminds us of the other side of the interpreting process - controllability of the interpretative activity and limitations of reading in new meanings. The paper points to the various theoretical basis on which Eco propagates the dialectics between the form and openness of a work of art, in other words, between intentio operis and intentio lectoris. This position enables him to differentiate art from nonart, as well as to consider interpretation of a work of art not as a self-sufficing process, but from the point of view of human experience.

Some challenges in eco-hydrology

Science.gov (United States)

Porporato, A.

2007-12-01

The importance of the mutual interactions between biosphere in hydrosphere has become increasingly apparent in both the ecological and hydrological sciences. In hydrology, while the role of plants in controlling soil water balance has been recognized from some time, more subtle controls have also been realized, such as the impact of soil organic matter on soil water dynamics and soil properties, the plant control on infiltration, erosion, and geomorphology. Ecosystem dynamics and land-use changes have also been recognized to impact water availability and quality. On the other hand, biologists and ecologists have increased their attention towards the dynamics of the terrestrial water balance and its impact on plants (photosynthesis, plant growth and reproduction) as well as microbial life (and thus decomposition and the entire cycling of nutrients and carbon fluxes). In this eco-hydrological context, we discuss: (i) the need to distinguish complex from complicated eco- hydrologic behaviors, which are both expected to be present in systems with many degrees of freedom, spatial heterogeneity, nonlinearities and feedbacks (and with biological components). (ii) The use of ideas and tools from complex systems science and non-equilibrium statistical mechanics to explore possible emerging behaviors and patterns. (iii) The importance of intermittency and of the entire spectrum of eco-hydrologic fluctuations conferred by the system nonlinearities, and their connection to a possible theory of biologically- meaningful hydroclimatic extremes. (iv) The need for further research of basic questions yet unanswered (e.g., role of organic matter/roots on soil water balance and soil properties; vegetation control on infiltration; competition for water by plants; role of plant control on uptake (e.g., hydraulic lift)). (v) Ways to merge observations, minimalist models and complex numerical simulations as well as to increase communication of hydrologists with physicists, statisticians

A new method of regional eco-environmental quality assessment and its application.

Wang, Xiaodan; Cao, Yingzi; Zhong, Xianghao; Gao, Pan

2012-01-01

Eco-environmental quality assessment (EQA) is an intricate and challenging task that must take into account numerous natural, economic, political, and social factors, which are subject to multiple conflicting criteria. In this paper, a methodological reference framework is developed for EQA that combines the fuzzy Delphi method (FDM) and fuzzy analytical hierarchy process (FAHP) with a geographic information system (GIS). The proposed method significantly improves the accuracy and reliability of evaluation results through the incorporation of fuzzy set theory. A GIS not only has the ability to store and analyze large amounts of spatial data from different sources but also provides a consistent visualization environment for displaying the input data and the results of EQA. Furthermore, unlike prior EQAs, the proposed method can support the dynamic estimation of regional eco-environmental quality by updating historical spatiotemporal data at little additional cost. A case study is presented for the western Tibetan Plateau. The study results show that worse, bad, and moderate eco-environmental quality classes comprised 16.58, 20.15, and 24.84% of the total area, respectively. Good and better eco-environmental quality classes accounted for 38.43%. This result indicates that nearly 62% of the total area is eco-environmentally vulnerable. The results verified the usefulness and feasibility of the proposed method. The EQA can also help local managers make scientifically based and effective decisions about Tibetan eco-environmental protection and land use.

Actualizing Communities of Practice (COPs and Situated Learning for A Sustainable Eco-Village

Directory of Open Access Journals (Sweden)

Maria Victoria Pineda

2016-05-01

Full Text Available An eco-village as defined by Robert Gilman is a “human-scale, full-featured settlement where you feel you know the others, and human activities are integrated with natural, biological systems.” Roland Mayerl argued that this maybe ideal, but there are huge challenges. He claims the challenges are at different levels—there is the physical layer that constitutes food production, animals, water and wastewater treatment. Other layers will be the built environment, the economic system and the governance in the village.This paper argues that one of the challenging layers is the human layer that was excluded in the modeling of many eco-village works. While there are many good models of an eco-village, sustainability will primarily be laid on the shoulders of the members of the community or the village for that matter. Sustainability should be espoused by the members of the eco-village. But how can sustainability be attained? What sustainability approach or strategy can be employed?“Communities of practice (COP are formed by people who engage in a process of collective learning in a shared domain of human endeavor.“ (Wenger, 2004 COPs are concepts commonly applied in organizations and virtual communities. Using this approach together with periphery participation and situated learning, this paper presents a human-based model of a sustainable eco-village and some useful examples.The paper also argues that an eco-village necessitates the support of technology in enhancing and preserving the shared practices. Hence, use of social media deployed in the web is one of the recommended ways that also permit collective action among members of the eco-village.

New Zealand (NZ) dairy farms used to be the lowest input and most efficient dairy farms of the world. However, intensification of the traditional pasture-based system has occurred over the last decade and has not always been accompanied by increased efficiency. The purpose of this paper is to produce an updated reference of the eco-efficiency of NZ dairy farm systems and to analyse the implications of intensification on their eco-efficiency. Results for an average NZ dairy farm system were compared with those for three dairy farmlet systems representing a wide range in intensification practices. A low input system (LI) (no N fertiliser, no brought-in feed supplement, stocking rate of 2.3 cows/ha) was compared with an N-fertilised farm system (NF) (170 kg fertiliser-N/ha/year, 3 cows/ha) representing a first level of intensification and with an N-fertilised and maize silage supplemented system (NFMS) (170 kg fertiliser-N/ha/year, 13 t DM maize silage/ha/year, 5.2 cows/ha), representing a possible future intensification option. Their eco-efficiency in terms of milk production and land use was compared using Life Cycle Assessment (LCA) methodology. NZ dairy farm systems rely on favourable temperate climate conditions and long-term perennial ryegrass/white clover pasture, to achieve eco-efficient milk production and land use compared to European systems. However, intensification of NZ dairy farms was shown to be detrimental to their eco-efficiency in terms both of milk production and land use functions and could greatly reduce their advantage compared to European systems. The eco-efficiency of LI was very high whatever the functional unit which is remarkable from an LCA perspective. NF and NFMS had a similar eco-efficiency except for energy use which corresponded to the most critical hot spot of NFMS. All studied NZ systems presented some areas for improvement where some new technologies available for dairy farms might play a promising role in the future. Finally, it

[Eco-epidemiology: towards epidemiology of complexity].

Science.gov (United States)

Bizouarn, Philippe

2016-05-01

In order to solve public health problems posed by the epidemiology of risk factors centered on the individual and neglecting the causal processes linking the risk factors with the health outcomes, Mervyn Susser proposed a multilevel epidemiology called eco-epidemiology, addressing the interdependence of individuals and their connection with molecular, individual, societal, environmental levels of organization participating in the causal disease processes. The aim of this epidemiology is to integrate more than a level of organization in design, analysis and interpretation of health problems. After presenting the main criticisms of risk-factor epidemiology focused on the individual, we will try to show how eco-epidemiology and its development could help to understand the need for a broader and integrative epidemiology, in which studies designed to identify risk factors would be balanced by studies designed to answer other questions equally vital to public health. © 2016 médecine/sciences – Inserm.

ECO-4601 is a structurally novel farnesylated dibenzodiazepinone discovered through DECIPHER technology, Thallion's proprietary drug discovery platform. The compound was shown to have a broad cytotoxic activity in the low micromolar range when tested in the NCI 60 cell line panel. In the work presented here, ECO-4601 was further evaluated against brain tumor cell lines. Preliminary mechanistic studies as well as in vivo antitumor evaluation were performed. Since ECO-4601 has a benzodiazepinone moiety, we first investigated if it binds the central and/or peripheral benzodiazepine receptors. ECO-4601 was tested in radioligand binding assays on benzodiazepine receptors obtained from rat hearts. The ability of ECO-4601 to inhibit the growth of CNS cancers was evaluated on a panel of mouse, rat and human glioma cell lines using a standard MTT assay. Antitumor efficacy studies were performed on gliomas (rat and human), human breast and human prostate mouse tumor xenografts. Antitumor activity and pharmacokinetic analysis of ECO-4601 was evaluated following intravenous (i.v.), subcutaneous (s.c.), and intraperitoneal (i.p.) bolus administrations. ECO-4601 was shown to bind the peripheral but not the central benzodiazepine receptor and inhibited the growth of CNS tumor cell lines. Bolus s.c. and i.p. administration gave rise to low but sustained drug exposure, and resulted in moderate to significant antitumor activity at doses that were well tolerated. In a rat glioma (C6) xenograft model, ECO-4601 produced up to 70% tumor growth inhibition (TGI) while in a human glioma (U-87MG) xenograft, TGI was 34%. Antitumor activity was highly significant in both human hormone-independent breast (MDA-MB-231) and prostate (PC-3) xenografts, resulting in TGI of 72 and 100%, respectively. On the other hand, i.v. dosing was followed by rapid elimination of the drug and was ineffective. Antitumor efficacy of ECO-4601 appears to be associated with the exposure parameter AUC and/or sustained

A Transcriptome—Targeting EcoChip for Assessing Functional Mycodiversity

Derek Peršoh

2011-10-01

Full Text Available A functional biodiversity microarray (EcoChip prototype has been developed to facilitate the analysis of fungal communities in environmental samples with broad functional and phylogenetic coverage and to enable the incorporation of nucleic acid sequence data as they become available from large-scale (next generation sequencing projects. A dual probe set (DPS was designed to detect a functional enzyme transcripts at conserved protein sites and b phylogenetic barcoding transcripts at ITS regions present in precursor rRNA. Deviating from the concept of GeoChip-type microarrays, the presented EcoChip microarray phylogenetic information was obtained using a dedicated set of barcoding microarray probes, whereas functional gene expression was analyzed by conserved domain-specific probes. By unlinking these two target groups, the shortage of broad sequence information of functional enzyme-coding genes in environmental communities became less important. The novel EcoChip microarray could be successfully applied to identify specific degradation activities in environmental samples at considerably high phylogenetic resolution. Reproducible and unbiased microarray signals could be obtained with chemically labeled total RNA preparations, thus avoiding the use of enzymatic labeling steps. ITS precursor rRNA was detected for the first time in a microarray experiment, which confirms the applicability of the EcoChip concept to selectively quantify the transcriptionally active part of fungal communities at high phylogenetic resolution. In addition, the chosen microarray platform facilitates the conducting of experiments with high sample throughput in almost any molecular biology laboratory.

Computational modeling for eco engineering: Making the connections between engineering and ecology (Invited)

Science.gov (United States)

Bowles, C.

2013-12-01

Ecological engineering, or eco engineering, is an emerging field in the study of integrating ecology and engineering, concerned with the design, monitoring, and construction of ecosystems. According to Mitsch (1996) 'the design of sustainable ecosystems intends to integrate human society with its natural environment for the benefit of both'. Eco engineering emerged as a new idea in the early 1960s, and the concept has seen refinement since then. As a commonly practiced field of engineering it is relatively novel. Howard Odum (1963) and others first introduced it as 'utilizing natural energy sources as the predominant input to manipulate and control environmental systems'. Mtisch and Jorgensen (1989) were the first to define eco engineering, to provide eco engineering principles and conceptual eco engineering models. Later they refined the definition and increased the number of principles. They suggested that the goals of eco engineering are: a) the restoration of ecosystems that have been substantially disturbed by human activities such as environmental pollution or land disturbance, and b) the development of new sustainable ecosystems that have both human and ecological values. Here a more detailed overview of eco engineering is provided, particularly with regard to how engineers and ecologists are utilizing multi-dimensional computational models to link ecology and engineering, resulting in increasingly successful project implementation. Descriptions are provided pertaining to 1-, 2- and 3-dimensional hydrodynamic models and their use at small- and large-scale applications. A range of conceptual models that have been developed to aid the in the creation of linkages between ecology and engineering are discussed. Finally, several case studies that link ecology and engineering via computational modeling are provided. These studies include localized stream rehabilitation, spawning gravel enhancement on a large river system, and watershed-wide floodplain modeling of

EcoTILLING in Capsicum species: searching for new virus resistances

Directory of Open Access Journals (Sweden)

Nuez Fernando

2010-11-01

Full Text Available Abstract Background The EcoTILLING technique allows polymorphisms in target genes of natural populations to be quickly analysed or identified and facilitates the screening of genebank collections for desired traits. We have developed an EcoTILLING platform to exploit Capsicum genetic resources. A perfect example of the utility of this EcoTILLING platform is its application in searching for new virus-resistant alleles in Capsicum genus. Mutations in translation initiation factors (eIF4E, eIF(iso4E, eIF4G and eIF(iso4G break the cycle of several RNA viruses without affecting the plant life cycle, which makes these genes potential targets to screen for resistant germplasm. Results We developed and assayed a cDNA-based EcoTILLING platform with 233 cultivated accessions of the genus Capsicum. High variability in the coding sequences of the eIF4E and eIF(iso4E genes was detected using the cDNA platform. After sequencing, 36 nucleotide changes were detected in the CDS of eIF4E and 26 in eIF(iso4E. A total of 21 eIF4E haplotypes and 15 eIF(iso4E haplotypes were identified. To evaluate the functional relevance of this variability, 31 possible eIF4E/eIF(iso4E combinations were tested against Potato virus Y. The results showed that five new eIF4E variants (pvr210, pvr211, pvr212, pvr213 and pvr214 were related to PVY-resistance responses. Conclusions EcoTILLING was optimised in different Capsicum species to detect allelic variants of target genes. This work is the first to use cDNA instead of genomic DNA in EcoTILLING. This approach avoids intronic sequence problems and reduces the number of reactions. A high level of polymorphism has been identified for initiation factors, showing the high genetic variability present in our collection and its potential use for other traits, such as genes related to biotic or abiotic stresses, quality or production. Moreover, the new eIF4E and eIF(iso4E alleles are an excellent collection for searching for new resistance

2017-12-01

As being the heartlands of international trade, sea ports are the junction points of land and sea routes. The growth of global trade has led to the development of number and capacity as well as the service quality of ports. The policies and procedures applied during construction, operation and development of ports under development with environmental considerations scope has evolved in accordance with the needs of global trends. Although maritime transportation provides the most ecofriendly transportation method, the reduction of potential environmental threats and continuous improvement of ports and their vicinity is paramount from environmental concerns with regards to the international environmental standards. In the context of the study, national and international legal regulations governing the control of the environmental impacts of the activity groups causing pollution in Turkey based sea ports were viewed. In addition, the models applied during the measurement and documentation of environmental impacts were investigated. The most important aspects in terms of the effectiveness of the environmental management models are legal regulations. However, the standards applied at the ports without any legal obligation, such as EcoPorts applications, ISO 14001 standard, and the EMAS (Eco-Management and Audit Scheme) were sought in the scope of the study. The boundaries of the study were determined as the EU based Environmental Management Systems and the Green Port/Eco Port Project which is being administered by the Turkish Ministry of Transport, Maritime and Communication. “Marport”, which is Turkey’s first certified Green Port / Eco Port is designated as the experimental study site. In addition, the provisions in the ports of ESPO member countries are approached in order to compare the effectiveness and applicability of Green Port / Eco Port Project.

Eco-Anthropic Compatibility - a Multidisciplinary Model in Urban Ecology

Directory of Open Access Journals (Sweden)

MARIANO L. BIANCA

2010-01-01

Full Text Available In this paper I propose a multidisciplinary model of urban development which goes beyond the notion of ecological sustainability, by building on the concept of eco-anthropic compatibility. First of all I will sketch the historical development of human aggregations and I will underline the difference between ancient and modern aggregations. On the basis of this analysis, I will take into consideration the notion of sustainability and its possible application to present conurbations. I will underline several limits of the notion of sustainable development and I will propose a multidisciplinary model grounded on a broader and new notion: the eco-anthropic compatibility. Using this notion, which includes the idea of sustainability, it is possible to handle, within the model, the human factors and human living conditions inside an urban aggregation. Finally, I will state that the actual urban model is decaying and therefore, sooner or later, we will have to face the end of urban civilization; for this reason we can start imagining new future ways for human aggregations on the planet based on the notion of eco-anthropic compatibility.

[Application of extended exergy method in driving mechanism and efficiency of regional eco-economy].

Fan, Xin Gang; Mi, Wen Bao; Hou, Jing Wei

2017-01-01

To analyze social-economic causes of the regional ecological degradation, and avoid such problems as the complex circulation network and difficulty to identify laws caused by extended exergy analysis (EEA) previously applied at the national scale, this paper reduced spatial scale to the county scale and took Pengyang County in Ningxia as an example. Eco-economic system in Peng-yang County was divided into seven interrelated sectors. The exergy value of circulations in the eco-economic system including materials, labor and capital were calculated respectively to analyze the extended exergy characteristics of the driving sectors, factors and paths and evaluate their ecological efficiency. The results showed that agriculture and households were the main driving sectors of the eco-economic system in Pengyang County. The average exergy value of 31 flow paths among the sectors was 0.80 PJ. There were only 8 flow paths whose exergy values were higher than the average value. Eco-economic system in Pengyang County development was driven by two continuous flow paths, labor output of the households sector and demands of the households sector supported by other sectors. The mineral resources were massively exploited, and then directly exported to the outside, which could not promote the local development from the inside, but, on the contrary, increase the ecological environment pressure because of the over-exploitation. The eco-efficiency of Pengyang County in 2014 was 68.1%, almost equivalent to the by-level of the national scale at home and abroad ten years ago, mainly because of the lower eco-efficiencies of the service sector and households sector. EEA had the advantage of networking and structuring, could specify the sectors, factors and driven paths, and break through the bottleneck of driving mechanism research of the eco-economic system. EEA had certain adaptability to explore the operational principle and optimal pattern of the regional eco-economic system. Compared

Power industry restructuring and eco-efficiency changes: A new slacks-based model in Malmquist–Luenberger Index measurement

Arabi, Behrouz; Munisamy, Susila; Emrouznejad, Ali; Shadman, Foroogh

2014-01-01

Measuring variations in efficiency and its extension, eco-efficiency, during a restructuring period in different industries has always been a point of interest for regulators and policy makers. This paper assesses the impacts of restructuring of procurement in the Iranian power industry on the performance of power plants. We introduce a new slacks-based model for Malmquist–Luenberger (ML) Index measurement and apply it to the power plants to calculate the efficiency, eco-efficiency, and technological changes over the 8-year period (2003–2010) of restructuring in the power industry. The results reveal that although the restructuring had different effects on the individual power plants, the overall growth in the eco-efficiency of the sector was mainly due to advances in pure technology. We also assess the correlation between efficiency and eco-efficiency of the power plants, which indicates a close relationship between these two steps, thus lending support to the incorporation of environmental factors in efficiency analysis. - Highlights: • We introduce a new slack-based model incorporating bad outputs to measure eco-efficiency. • Eco-efficiency change of power plants is measured over a restructuring period. • A success to enhance the eco-efficiency is revealed. • A close relationship between efficiency and eco-efficiency is shown

Full Text Available The paper aims to present some eco-innovative practices regarding Sustainable Consumption and Production (SCP. The study also focuses on potential benefits for the actors who implement these practices, mainly with reference to companies. After a literature review on the actual importance of SCP and on the effects of eco-innovation tools and policies on companies, authors present the developed eco-innovation practices in three focus areas related to sustainable consumption and production. The aim of the study is to contribute to literature studies on SCP with the development of eco-innovative practices resulting by the integration of existing tools, by pointing out and valorizing their potentials and synergies. These practices have been pointing out in the framework of the international European project. Three focus areas are involved by the practices: sustainability of products and services, sustainability of production processes and sustainable management of industrial areas. Authors developed four eco innovative practices resulting from the integration of 15 existing tools. These practices offer many opportunities to many actors, mainly companies and public authorities, in order to achieve environmental and competitive benefits and implement eco-innovation principles with a cooperative and shared approach.

Highlights: ► The results of X-ray diffraction (XRD) pattern and scanning electron micrograph (SEM) indicated that the major components in the eco-cement clinkers were similar to those in ordinary Portland cement. ► Though the C 2 S phase formation increased with the increase of sewage sludge contents. ► All the eco-cement pastes had a longer initial setting time and final setting time than those of plain cement paste, which increased as the sewage sludge contents in raw meal increased. ► All the eco-cement pastes had lower early flexural strengths and it increased with the increase of sewage sludge contents increased, while the compressive strengths decreased slightly. ► However, it had no significant effect on all the strengths at later ages. - Abstract: The effects of using dried sewage sludge as additive on cement property in the process of clinker burning were investigated in this paper. The eco-cement samples were prepared by adding 0.50–15.0% of dried sewage sludge to unit raw meal, and then the mixtures were burned at 1450 °C for 2 h. The results indicated that the major components in the eco-cement clinkers were similar to those in ordinary Portland cement. Although the C 2 S phase formation increased with the increase of sewage sludge content, it was also found that the microstructure of the mixture containing 15.0% sewage sludge in raw meal was significantly different and that a larger amount of pores were distributed in the clinker. Moreover, all the eco-cement pastes had a longer initial setting time and final setting time than those of plain cement paste, which increased as the sewage sludge content in the raw meal increased. All the eco-cement pastes had lower early flexural strengths, which increased as the sewage sludge content increased, while the compressive strengths decreased slightly. However, this had no significant effect on all the strengths at later stages. Furthermore, the leaching concentrations of all the types of eco

Wahlgren, Irmeli

2007-01-01

Urban planning and transportation system solutions and decisions have a large-scale significance for eco efficiency, the consumption of energy and other natural resources, the production of greenhouse gas and other emissions, and the costs caused by communities.Planning solutions may impact on greenhouse gas emissions by 10 % at regional level, by 20 % at local community level and even by 200 % at local dwelling area level. Impact on emissions caused by transportation is even bigger: at least double compared to the impact on total emissions. Similarly large impacts can be seen concerning consumption of energy and other natural resources as well as costs.The most important factors in sustainable urban and transportation planning are at dwelling area level: location, structure, building density, house types, space heating systems, at community and regional level: area density, energy consumption and production systems, location of and distances between dwellings, working places and services, transportation systems, possibilities of walking and cycling, availability of public transport, and necessity for use of private cars. The presentation is based on the author's research and case studies from 1992 to 2006. The assessment method EcoBalance was developed to assess sustainability of communities and it has been applied at different planning levels: regional plans, local master plans and detailed plans. The EcoBalance model estimates the total consumption of energy and other natural resources, the production of emissions and wastes and the costs caused directly and indirectly by communities on a life-cycle basis

Highlights: • Sugarcane biorefinery in Thailand is evaluated using the eco-efficiency concept. • Green cane along with cane trash use for electricity yields highest eco-efficiency. • Proposed biorefinery system increases eco-efficiency by 20–70%. - Abstract: The study aims to evaluate the sugarcane biorefinery and molasses ethanol production in Thailand using the combined environmental and economic sustainability indicator, so called “Eco-efficiency”. Four sugarcane biorefinery scenarios in Thailand are evaluated. The total output values (US$) and the life cycle greenhouse gas (GHG) emissions (kg CO_2eq) are selected as the indicators for characterizing economic and environmental performance, respectively. The results show that the biorefinery system of mechanized farming along with cane trash utilization for power generation yields the highest eco-efficiency. The benefits come from the increased value added of the biorefinery together with the decreased GHG emissions of the biorefinery system. As compared to the base case scenario, the new systems proposed result in the eco-efficiency improvement by around 20–70%. The biorefinery concept induces reduction of GHG emissions attributed to molasses ethanol. Green cane production and harvesting results in further lowering of the GHG emissions. Integration of sugarcane biomass utilization across the entire sugarcane complex would enhance the sustainability of the sugarcane production system.

China's urban population surpassed its rural population historically in 2011, when the number of Chinese living in towns and cities reached about 690 million1. In the years to come, cities in China will face major challenges as their rapidly increasing populations burden already crowded infrastructure systems and exacerbate environmental and climate change issues, threatening public health and quality of life. Low-carbon cities may be key to addressing those challenges, especially as regards mitigating and adapting to climate change. Government entities at both the central and local level have moved aggressively on building low-carbon eco-cities. According to statistics reported by the Chinese Society for Urban Studies, by February of 2011, China will have 230 cities at the prefecture-and-above level that have proposed to establish themselves as “eco-cities,” accounting for 80.1% of the 287 such cities nationally. Of those 230 cities, 133, or 46.3%, have established targets to develop specifically as “lowcarbon cities” (Chinese Society for Urban Studies 2011). Given the proposed scale of the effort, China’s potential success or failure in demonstrating and implementing low-carbon eco-cities could greatly affect how the world addresses both the climate change impacts of urbanization and the sustainable development of cities. Despite the multiple guidelines that have been developed, it remains unclear what defines a low-carbon eco-city. Additionally, although more than 100 indicators have been used or proposed for assessing such cities, few relate directly to energy use or carbon emissions. Nonetheless, policy makers and leaders continue to demand comprehensive toolboxes to facilitate development of low-carbon eco-cities. This paper presents the results of an extensive literature review of the development of low-carbon eco-cities in China. The paper also qualitatively and quantitatively analyzes 11 major indicator systems that researchers, planners

This article takes a look at the various eco-power offers that can currently be found on the Swiss electricity market. Various electricity utilities offer ecologically produced power in various qualities under several different names. These range from pure solar power through to various mixes of solar, wind and hydro power. The varying marketing approaches used are discussed. Local utilities have the most success in selling eco-power, whereas a large Swiss supermarket chain had difficulty selling its customers certificates for renewable electricity. This, according to the chain's speaker, was due to the difficulty of explaining the relationship between production certificates and the actual power drawn from the wall socket. The offers of various utilities and independent power producers are looked at and discussed with those responsible

The Chinese government has conducted the Returning Grazing Land to Grassland Project (RGLGP) across large portions of grasslands from western China since 2003. In order to explore and understand the impact in the grassland's eco-environment during the RGLGP, we utilized Projection Pursuit Model (PPM) and Geographic Information System (GIS) to develop a spatial assessment model to examine the ecological vulnerability of the grassland. Our results include five indications: (1) it is practical to apply the spatial PPM on ecological vulnerability assessment for the grassland. This methodology avoids creating an artificial hypothesis, thereby providing objective results that successfully execute a multi-index assessment process and analysis under non-linear systems in eco-environments; (2) the spatial PPM is not only capable of evaluating regional eco-environmental vulnerability in a quantitative way, but also can quantitatively demonstrate the degree of effect in each evaluation index for regional eco-environmental vulnerability; (3) the eco-environment of the Xianshui River Basin falls into the medium range level. The normalized difference vegetation index (NDVI) and land use cover and change (LUCC) crucially influence the Xianshui River Basin's eco-environmental vulnerability. Generally, in the Xianshui River Basin, regional eco-environmental conditions improved during 2000 and 2010. The RGLGP positively affected NDVI and LUCC structure, thereby promoting the enhancement of the regional eco-environment; (4) the Xianshui River Basin divides its ecological vulnerability across different levels; therefore our study investigates three ecological regions and proposes specific suggestions for each in order to assist in eco-environmental protection and rehabilitation; and lastly that (5) the spatial PPM established by this study has the potential to be applied on all types of grassland eco-environmental vulnerability assessments under the RGLGP and under the similar

Regional land use/land cover (LULC) changes lead to various changes in ecological processes and, in turn, alter regional micro-climate. To understand eco-environmental responses to LULC changes, eco-environmental evaluation is thus required with aims to identify vulnerable regions and influential factors, so that practical measures for environmental protection and management may be proposed. The Thua Thien - Hue Province has been experiencing urbanization at a rapid rate in both population and physical size. The urban land, agricultural land, and aquaculture activities have been invasively into natural space and caused eco-environment deterioration by land desertification, soil erosion, shrinking forest resources,…etc. In this study, an assessment framework that is composed by 11 variables with 9 of them constructed from Landsat time series is proposed to serve as basis to examine eco-environmental vulnerability in the Thua Thien - Hue Province in years 1989, 2003, and 2014. An eco-environmental vulnerability map is assorted into six vulnerability levels consisting of potential, slight, light, medium, heavy, and very heavy vulnerabilities. Result shows that there is an increasing trend in eco-environmental vulnerability in general with expected evolving distributions in heavy and very heavy vulnerability levels, which mainly lying on developed land, bare land, semi bare land, agricultural land, and poor and recovery forests. In contrast, there is a significant decline in potential vulnerability level. The contributing factors of an upward trend in medium, heavy, and very heavy levels include: (i) a large natural forest converted to plantation forest and agriculture land; and (ii) significant expansion of developed land leading to difference in thermal signatures in urban areas as compared with those of the surrounding areas. It is concluded that anthropogenic processes with transformation on LULC has amplified the vulnerability of eco-environment in the study

This paper analyzes a set of selected German and French cities' performance in terms of the relative behavior of their eco-efficiencies, computed as the ratio of their gross domestic product (GDP) over their CO 2 emissions. For this analysis, eco-efficiency scores of the selected cities are computed using the data envelopment analysis (DEA) technique, taking the eco-efficiencies as outputs, and the inputs being the energy consumption, the population density, the labor productivity, the resource productivity, and the patents per inhabitant. Once DEA results are analyzed, the Malmquist productivity indexes (MPI) are used to assess the time evolution of the technical efficiency, technological efficiency, and productivity of the cities over the window periods 2000 to 2005 and 2005 to 2008. Some of the main conclusions are that (1) most of the analyzed cities seem to have suboptimal scales, being one of the causes of their inefficiency; (2) there is evidence that high GDP over CO 2 emissions does not imply high eco-efficiency scores, meaning that DEA like approaches are useful to complement more simplistic ranking procedures, pointing out potential inefficiencies at the input levels; (3) efficiencies performed worse during the period 2000-2005 than during the period 2005-2008, suggesting the possibility of corrective actions taken during or at the end of the first period but impacting only on the second period, probably due to an increasing environmental awareness of policymakers and governors; and (4) MPI analysis shows a positive technological evolution of all cities, according to the general technological evolution of the reference cities, reflecting a generalized convergence of most cities to their technological frontier and therefore an evolution in the right direction.

Among the problems common to all mankind, which solutions influence the prospects of civilization, the problem of ecological situation monitoring takes very important place. Solution of this problem requires specific methodology based on eco-analytical comprehension of global issues. Eco-analytical methodology should help searching for the optimum balance between environmental problems and accelerating scientific and technical progress. The fact that Governments, corporations, scientists and nations focus on the production and consumption of material goods cause great damage to environment. As a result, the activity of environmentalists is developing quite spontaneously, as a complement to productive activities. Therefore, the challenge posed by the environmental problems for the science is the formation of geo-analytical reasoning and the monitoring of global problems common for the whole humanity. So it is expected to find the optimal trajectory of industrial development to prevent irreversible problems in the biosphere that could stop progress of civilization.

In this paper, Shanghai Chenshan Botanical Garden, China has been selected as the study area. The overall status and the development conditions of resources and environment have been analyzed for the park. The eco-tourism resources and environment of Chenshan Botanical Garden were further evaluated synthetically by using expert analysis and questionnaire. A comprehensive evaluation system including 16 indices has been initially established from three aspects of tourism resource element value, resource development condition and eco-environment condition. The characteristics of eco-tourism resources and the score of each indicator for Chenshan Botanical Garden have subsequently been generated. The results show that the comprehensive evaluation score of eco-tourism resources and environment for Shanghai Chenshan Botanical Garden is 72.06, which belongs to third level of excellent tourism resources and environment. Finally, five suggestions are proposed for future development of its eco-tourism resources and environment.

Spatio-temporal variability of several eco-precipitation indicators in China

2016-12-01

Climate change is expected to have large impacts on the eco-hydrological processes. Precipitation as one of the most important meteorological factors is a significant parameter in ecohydrology. Many studies and precipitation indexes focused on the long-term precipitation variability have been put forward. However, these former studies did not consider the vegetation response and these indexes could not reflect it efficiently. Eco-precipitation indicators reflecting the features and patterns of precipitations and serving as significant input parameters of eco-hydrological models are of paramount significance to the studies of these models. Therefore we proposed 4 important eco-precipitation indicators—Precipitation Variability Index (PVI), Precipitation Occurrence Rate (λ), Mean Precipitation Depth (1/θ) and Annual Precipitation (AP). The PVI index depicts the precipitation variability with a value of zero for perfectly uniform and increases as precipitation events become more sporadic. The λ, 1/θ and AP depict the precipitation frequency, intensity and annual amount, respectively. With large precipitation and vegetation discrepancies, China is selected as a study area. Firstly, these indicators are calculated separately with 55-years (1961-2015) daily precipitation time-series from 693 weather stations in China. Then, the temporal trend is analyzed through Mann-Kendall (MK) test and parametric t-test in annual time scale. Furthermore, the spatial distribution is analyzed through the spatial interpolation tools ANUsplin. The result shows that: (1) 1/θ increased significantly (4.59cm/10yr) while λ decreased significantly (1.54 days/10yr), which means there is an increasing trend of extreme precipitation events; (2)there is a significant downward trend of PVI, which means the rhythm of precipitation has a uniform and concentrated trend; (3) AP increased insignificantly (0.57mm/10yr); and (4)the MK test of these indicators shows that there is saltation of �

Las premisas de argumento son: la justicia global y la soberanía ciudadana son exigencias de la sustentabilidad eco-política y, a su vez, la Democracia Líquida es el modelo que por excelencia promueve la justicia y la soberanía. El corolario es que la Democracia Líquida es la modalidad idónea para la consolidar también al eco-desarrollo. El argumento obliga a explicar conceptos medulares: sustentabilidad, uso de recursos, sentido del consumo. Para lo cual se destacan apreciaciones axiológicas de la biosfera: desde la teología hasta la economía. A su vez, el debate sobre el consumismo se enmarca en la sustentabilidad ampliada más allá de los límites de la ecología. Todo lo anterior suma argumentos a favor de la eco-política ejercida con la Democracia Líquida como la mejor instancia para la elaboración de las políticas ambientales.

Full Text Available Remanufacturing can bring considerable economic and environmental benefits such as cost saving, conservation of energy and resources, and reduction of emissions. With the increasing awareness of sustainable manufacturing, remanufacturing gradually becomes the research priority. Most studies concentrate on the analysis of influencing factors, or the evaluation of the economic and environmental performance in remanufacturing, while little effort has been devoted to investigating the critical factors influencing the eco-efficiency of remanufacturing. Considering the current development of the remanufacturing industry in China, this paper proposes a set of factors influencing the eco-efficiency of remanufacturing and then utilizes a fuzzy Decision Making Trial and Evaluation Laboratory (DEMATEL method to establish relation matrixes reflecting the interdependent relationships among these factors. Finally, the contributions of each factor to eco-efficiency and mutual influence values among them are obtained, and critical factors in eco-efficiency of remanufacturing are identified. The results of the present work can provide theoretical supports for the government to make appropriate policies to improve the eco-efficiency of remanufacturing.

Full Text Available This paper examines the application of life cycle assessment (LCA as an approach to foster the product and process oriented eco- innovation of enterprises, using the fruit and vegetable processing plant as an example. LCA, which is traditionally used to assess the impacts of a single product system on the environment, was applied in the enterprise context. This was made possible by forming an indicator describing the environmental profile of an enterprise, which is calculated by the sum of the multiplication of the environmental impact assessment (LCIA results for individual unit processes within a particular impact category and their weights reflecting the structure of production in an enterprise. In order to distinguish and indicate the direction in which an enterprise should undertake its eco-innovative actions (implementing eco-innovations within the product or production process the LCIA results are presented individually for products and production processes. The research was conducted in full compliance with the LCA methodology. LCA proved that the analysed enterprise has the largest negative impacts on the environment in the following impact categories: marine eco-toxicity, freshwater eco-toxicity, freshwater eutrophication, human toxicity and natural land transformation. They result primarily from the consumption of thermal and electric energy in the production processes. Therefore, to improve energy efficiency, the enterprise should take eco-innovative actions in the processes applied.

In this study human motor cortical activity was recorded with a customized micro-ECoG grid during individual finger movements. The quality of the recorded neural signals was characterized in the frequency domain from three different perspectives: (1) coherence between neural signals recorded from different electrodes, (2) modulation of neural signals by finger movement, and (3) accuracy of finger movement decoding. It was found that, for the high frequency band (60-120 Hz), coherence between neighboring micro-ECoG electrodes was 0.3. In addition, the high frequency band showed significant modulation by finger movement both temporally and spatially, and a classification accuracy of 73% (chance level: 20%) was achieved for individual finger movement using neural signals recorded from the micro-ECoG grid. These results suggest that the micro-ECoG grid presented here offers sufficient spatial and temporal resolution for the development of minimally-invasive brain-computer interface applications.

2015-01-01

This paper mainly compares total factor productivity and eco-efficiency in China's cement manufactures from 2005 to 2010. First, we evaluate total factor productivity and eco-efficiency of China's cement manufactures through distance function and directional slack-based measure (DSBM) respectively. Furthermore, we also explore the difference of total factor productivity and eco-efficiency. Last, we investigate the determinants of Malmquist, Mamlquist–Luenberger of China's cement manufactures through random-effect Tobit and bootstrap truncated econometric methods. We find that there are some gaps between Malmquist and Mamlquist–Luenberger of China's cement manufactures. Per labor cement industry value has U-shape relationship with both Malmquist and Malmquist–Luenberger. It is necessary to adopt advanced technology to reduce pollutant emissions. -- Highlights: •Eco-efficiency of cement manufactures is evaluated through slack-based measure. •Eco-efficiency of China's cement manufactures has biases with total factor productivity. •Environmental Kuznets curve is existed for China's cement manufactures

Full Text Available Small and medium sized companies (SMEs assure economic growth in Europe. The Environmental Technologies Action Plan (ETAP concentrated and mobilized Member State and stakeholder efforts bringing eco-innovation from research to market, improving market conditions, opening up global markets. Rapid and reinforced actions are now required, building on the experience of ETAP helping SMEs to have benefits by introducing eco-innovative approaches into their operations. Particularly start-ups, can be the ideal incubators for eco-innovation, and can bring to market new, less environmentally damaging products, services and processes. Generally many SMEs are struggling to survive in an ongoing global recession and often they are becoming reluctant to release innovation, particularly eco-innovation (Assante et al., 2016. In this paper we present first the differences between eco-innovation based business models and those based on regular innovations. Secondly we give some approaches tested in national and European projects with participation of the authors in order to help SMEs to develop business models of eco-innovations. The first one is to build cooperation between researchers, educators and SME staff in order to explain SMEs the advantages of such models and to implement models designed by researchers. Secondly we used practice oriented forms of training for SMEs like Problem Based Learning (PBL as an efficient form for SMEs and entrepreneurship education to learn to solve problems like the building of an eco-innovation business model. Thirdly we use in our projects eco-innovation biographies (EIBs reflecting the evolutionary character of such innovations and the dynamics of related policy streams.

Background Access to the information concerning blood safety is essential for managing problems and overcoming the challenges that are faced in any given region. Information on the availability and safety of blood in countries of the Economic Cooperation Organisation (ECO) is largely lacking. To address this problem, the Iranian Blood Transfusion Organisation, in collaboration with other ECO member states, initiated a research project in 2009 to collect, analyse and compare statistics on blood safety in the region. Materials and methods A modified and summarised version of the Global Database on Blood Safety (GDBS) questionnaire was used to collect data. The questionnaire was sent to all ten countries in the ECO region. The heads of the national transfusion services or focal points were requested to complete the form. Related literature and websites were also reviewed. Results Only three countries (Afghanistan, Iran and Turkey) completed the questionnaire, while other countries provided their available data on some parts of the questionnaire. The number of donations per year varied from 5 to 27/1,000 population. The rate of donors positive for human immunodeficiency virus ranged from 0.003% to 0.2%. The rate of donors positive for hepatitis C virus antibody varied from 0.05% to 3.9% while that of hepatitis B virus surface antigen ranged from 0.15% to 3.91% respectively. Discussion There is very clear diversity in blood transfusion services among ECO member states. Most countries in the region do not have a data-recording system. It is generally estimated that the need for blood is much higher than the supply in this region. Deficiencies in donor screening and a high prevalence of transfusion-transmitted infections are other important challenges. PMID:26192779

China's industrial parks have been playing a crucial role on driving regional economy development, but also been posing threats to local environment due to intensive resource consumption and waste emission. Chinese government facilitated eco-industrial development of industrial park, aiming to output more with less environmental burden. In our study, the eco-efficiency levels of 40 Chinese industrial parks in 2012 were assessed and ranked by Data Envelopment Analysis (DEA). This paper applied indicators relevant to resource, economy, and environment from industrial parks which can well reflect the characteristics of eco-efficiency conforming to the concept of sustainability. This paper introduced how to adjust less sustainable parks to be more sustainable according to the DEA results. The roles of industrial added value per capita, industrial structure, environmental policy and development scale as influence factors of eco-efficiency were discussed. The results show that large differences exist in the eco-efficiency of different industrial parks. It is shown that 20% of the parks are relatively efficient. 47% of the study parks being inefficient in terms of scale efficiency show decreasing returns to scale. Policy implementations for the management of industrial parks were also discussed based on the results. Copyright © 2017 Elsevier Ltd. All rights reserved.

In 1998 IEFE Bocconi University (Italy) carried out a project for the diffusion of the European Commission Eco label, the certification of the environmental quality of products. What clearly emerges from this experience is that some Italian SMEs, among the most innovative and market-oriented, are prone and ready to grasp the opportunities connected with the Eco label adoption. The more these enterprises are capable of starting up a network of socio-institutional actors eager to support them in promoting the environmental quality of their products, the more they succeed in exploiting the above mentioned opportunities [it

Redealing the cards: How an eco-industry modifies the political economy of environmental taxes

International Nuclear Information System (INIS)

Canton, Joan

2008-01-01

This article presents a combined economic-political model of environmental taxation setting. The model introduces a third lobby group - the lobby of an eco-industry - in addition to the traditional lobbies of polluting firms and environmentalists. Pressure groups interact to influence the environmental tax chosen by a regulator maximizing its chances of being reelected. The eco-industry lobby adds a new political contribution toward a higher environmental tax. The imperfectly competitive structure of the eco-industry also modifies the incentives of the usual lobbies. When the foreign environmental policy is constant, environmentalists can be in favor of a decrease in the local tax in order to reduce foreign pollution. We also discuss the formation of alliances between the eco-industry and one of the other lobbies and their potential impact. In general, the impact of lobbying activities on the politically optimal tax is ambiguous and depends on the relative concentration of each pressure group. (author)

The reality of fiction: the ECO by Mathias Goeritz

Directory of Open Access Journals (Sweden)

Fernando Quesada

2016-05-01

Full Text Available Abstract This article covers the full biography of a building, the Experimental Museum El Eco, designed by Germanborn and Mexican émigré artist and architect Mathias Goeritz. It provides an approach intersecting the biography of the author, the history of the building, and prominent  individuals of the two cultural traditions, German and Mexican, who  participated in the creation of a very special and unique building: El Eco. On the one hand, the ethics of Expressionism, the interest in  non-European art, the cult of primitivism and the aesthetic system of the  pair of concepts abstraction-empathy, all stemming from German culture. On the other, the pantheistic religiosity of landscape, zoomorphism and anthropomorphism, the interest in masks, and the aesthetics of  monumental scale, stemming from pre-Cortesian Mexican culture. Taking  the stance of intertwining Mathias Goeritz parcours with those of individuals and issues from his German past and his Mexican future – highlighting the figures of Wilhelm Worringer, Paul Westheim, Luis Barragán, Edmundo O'Gorman, and Ida Rodríguez Prampolini – this article proposes a return  trip from fiction to reality, following in the footsteps of the author and  comparing them with the pathway of the very building El Eco.

Integrating reverse logistics and eco-design: a proposal for a new framework

Directory of Open Access Journals (Sweden)

Felipe Kich Gontijo

2014-07-01

Full Text Available The concepts of Reverse Logistics and Eco-design are discussed in this paper, suggesting that these applications are often treated differently, thus not being able to achieve a higher performance in relation to environmental sustainability. The reason is most reverse logistics applications have a repairer action, since their waste generation is not planned along with product design. The proposal shows how the two concepts can work together, describing the time of each application.Unfolding the two concepts into reverse channels concerning logistics and life cycle analysis of the product as per eco-design, an application model has been developed, promoting integration between the two practices, so that the reverse supply chain is planned along with the product.The result is the development of a model for implementing reverse logistics integrating eco-design, thus optimizing the reverse flow of waste.

Keum, Y. T.; Lee, S. Y.; Lee, T. H.; Sim, J. K.

2013-12-01

In order to manufacture an eco-friendly stud, the sheared pattern is designed by the Taguchi method and expanded by the side rolls. The seven geometrical shape of sheared pattern are considered in the structural and thermal analyses to select the best functional one in terms of the durability and fire resistance of dry wall. For optimizing the size of the sheared pattern chosen, the L9 orthogonal array and smaller-the-better characteristics of the Taguchi method are used. As the roll gap causes forming defects when the upper-and-lower roll type is adopted for expanding the sheared pattern, the side roll type is introduced. The stress and strain distributions obtained by the FEM simulation of roll-forming processes are utilized for the design of expanding process. The expanding process by side rolls shortens the length of expanding process and minimizes the cost of dies. Furthermore, the stud manufactured by expanding the sheared pattern of the web is an eco-friend because of the scrapless roll-forming process. In addition, compared to the conventionally roll-formed stud, the material cost is lessened about 13.6% and the weight is lightened about 15.5%.

Toward the Eco-Narrative: Rethinking the Role of Conflict in Storytelling

Directory of Open Access Journals (Sweden)

Corinne Donly

2017-04-01

Full Text Available Offered as a response to the increasingly popular call within the eco-humanities for stories that will help humankind adapt to catastrophic planetary conditions, this article proposes “the eco-narrative”—an approach to storytelling that strives to compose with, not for, its nonhuman characters. An extension of eco-critical projects that analyze stories for their depictions of nonhumanity, the theoretical research herein brings ecological analysis of narrative to the level of structure. In particular, it problematizes the dominant plot model of conflict/climax/resolution, suggesting that stories motivated by conflict reinforce dualistic and anthropocentric habits for approaching the animal other. Evaluating two narratives concerning the human practice of killing animals—the Pew Commission’s report on Industrial Farm Animal Production and Annette Watson and Orville H. Huntington’s “They’re here—I can feel them”—the article observes how the former’s efforts at animal rights advocacy are undermined by its very storytelling framework. Celebrating the latter story’s more playful approach to narrative instead, the article ultimately suggests that a theory of “infinite play,” as developed by James P. Carse, can be used to re-envision the dominant plot model. A template for cooperation in the absence of known outcome, infinite play thus becomes the basis for the eco-narrative—a storytelling framework flexible enough to cocreate with nonhumanity, even during an environmental moment characterized by crisis.

Prediction of three-dimensional arm trajectories based on ECoG signals recorded from human sensorimotor cortex.

Directory of Open Access Journals (Sweden)

Yasuhiko Nakanishi

Full Text Available Brain-machine interface techniques have been applied in a number of studies to control neuromotor prostheses and for neurorehabilitation in the hopes of providing a means to restore lost motor function. Electrocorticography (ECoG has seen recent use in this regard because it offers a higher spatiotemporal resolution than non-invasive EEG and is less invasive than intracortical microelectrodes. Although several studies have already succeeded in the inference of computer cursor trajectories and finger flexions using human ECoG signals, precise three-dimensional (3D trajectory reconstruction for a human limb from ECoG has not yet been achieved. In this study, we predicted 3D arm trajectories in time series from ECoG signals in humans using a novel preprocessing method and a sparse linear regression. Average Pearson's correlation coefficients and normalized root-mean-square errors between predicted and actual trajectories were 0.44~0.73 and 0.18~0.42, respectively, confirming the feasibility of predicting 3D arm trajectories from ECoG. We foresee this method contributing to future advancements in neuroprosthesis and neurorehabilitation technology.

We discuss a new EcoDesign method, with a goal of improving the economy, and its application to a sustainable networked society. The new EcoDesign method differs from conventional EcoDesign in three respects: it utilizes a top-down approach, project-style research, and fact-finding and benchmarking. We systematize EcoDesign for a networked society from the viewpoint of technology and divide it into four components. Feasibility studies of the individual components reveal that if we promote ICT diffusion with EcoDesign in mind, we can suppress CO2 emissions and move towards a more sustainable society. (orig.)

Flexural fatigue failures and lives of Eco-Core sandwich beams

Hossain, Mohammad Mynul; Shivakumar, Kunigal

2014-01-01

Highlights: • Eco-Core sandwich beam is flexural fatigue tested to study its fatigue response. • The core showed three failure types: damage onset, progression and final failure. • These failures were found to be represented by 1%, 5% and 7% change in compliance. • The fatigue stress-life (S–N) relationship follows a power low, σ max /σ ct = A o N α . • The fatigue failure was by multiple vertical cracks followed by 45° shear failure. - Abstract: Eco-Core is a class of syntactic foam made from small volume of high char yield binder and large volume of a class of flyash for fire resistance application. Very little or no flexural fatigue data of this class of core material is reported in the open literature. This paper presents a flexural fatigue response of Eco-Core in a glass/vinyl ester composite face sheet sandwich beam. A four-point loaded flexural test specimen was designed and tested in static and fatigue loadings to cause tension failure in the core. The fatigue test was conducted at maximum cyclic stress (σ max ) ranged from 0.7σ ct to 0.9σ ct , where σ ct is the static flexural strength of the core. The sinusoidal loading frequency of 2 Hz with the stress ratio of 0.1 was used. Flexural fatigue failure modes of Eco-Core sandwich beam were classified: damage onset (single tension crack), damage progression (multiple tension cracks) and ultimate failure (a combination of tension and shear). These failures were characterized by 1%, 5% and 7% changes in compliance that corresponds to N 1% , N 5% and N 7% lives. The fatigue stress-life (S–N) relationship was found to follow the well-known power law equation, σ max /σ ct = A o N α . The constants A o and α were established for all three types of failures. The endurance limit was established based on 1 million cycles limit and it was found to be 0.65σ ct , 0.70σ ct and 0.71σ ct , respectively for the three modes of failure.

Global food security requires eco-efficient agriculture to produce the required food and fiber products concomitant with ecologically efficient use of resources. This eco-efficiency concept is used to diagnose the state of agricultural production in China (irrigated wheat-maize double-cropping systems), Zimbabwe (rainfed maize systems), and Australia (rainfed wheat systems). More than 3,000 surveyed crop yields in these three countries were compared against simulated grain yields at farmer-specified levels of nitrogen (N) input. Many Australian commercial wheat farmers are both close to existing production frontiers and gain little prospective return from increasing their N input. Significant losses of N from their systems, either as nitrous oxide emissions or as nitrate leached from the soil profile, are infrequent and at low intensities relative to their level of grain production. These Australian farmers operate close to eco-efficient frontiers in regard to N, and so innovations in technologies and practices are essential to increasing their production without added economic or environmental risks. In contrast, many Chinese farmers can reduce N input without sacrificing production through more efficient use of their fertilizer input. In fact, there are real prospects for the double-cropping systems on the North China Plain to achieve both production increases and reduced environmental risks. Zimbabwean farmers have the opportunity for significant production increases by both improving their technical efficiency and increasing their level of input; however, doing so will require improved management expertise and greater access to institutional support for addressing the higher risks. This paper shows that pathways for achieving improved eco-efficiency will differ among diverse cropping systems.

A Threefold Assessment of the Romanian Economy’s Eco-efficiency

Directory of Open Access Journals (Sweden)

Viorel Niţă

2012-12-01

Full Text Available The present paper assesses the ecological sustainability of the Romanian economy from three different angles. The first two applications use the economy's energy and material consumption as proxy for its overall environmental impact. The third assessment approach is a qualitative and context-based one: the main obstacles to and opportunities for incorporating sustainability-competitiveness synergies into the Romanian industrial firms' management are identified. In the period 2000-2007, GDP growth was an important contributor to the Romanian economy's eco-efficiency levels, while the material and energy consumption remained constant or even increased. The predominance of competitive advantages based on low labour costs, high potential of increasing labour productivity, deficient environmental and industrial policies, and lack of awareness in both business and policy environment as to the beneficial role of resource productivity increase constitute significant obstacles to adopting competitive sustainability strategies. Fortunately, the relatively low levels of eco-efficiency and eco-innovation in industry offer in fact a wide scope of still unexploited win-win solutions. On the basis of the results, further research directions are sketched and several desirable public policy actions for enhancing the ecological sustainability of the Romanian economy are put forward.

Computerized testing in the elderly has multiple advantages, including increased time-efficiency, a wider range of stimulus options and response forms, and increased psychometric reliability. The French-language ECO (Examen Cognitif par Ordinateur, Ritchie et al., 1993) computerized cognitive battery is investigated in this study. The purpose of the study was to yield normative data for an English-language version of the ECO, test the effects of age and education on test scores, to observe individual subtest sensitivity to cognitive impairment, and to examine participants' receptivity to this form of testing. A sample of 129 community-dwelling elderly with normal cognitive functioning and 56 cognitively impaired older adults living in both independent and supported accommodation were tested using the ECO at either their own residence or an outpatient facility. Standardized scores for three different age bands are given for both impaired and non-impaired groups. Age and education effects varied between subtests. A discriminant analysis of subtest-sensitivity to group prediction is reported using a stepwise regression model. The English version of the ECO appears to be a sensitive and practical cognitive battery that is highly acceptable to older people.

2017-04-01

There have been long debates about the environment conscious (ECO) Mg technology which utilizes CaO to produce Ca-containing Mg alloys. Two key process technologies of the ECO-Mg process are the chemical reduction of CaO by liquid Mg and the maintenance of melt cleanliness during the alloying of Ca. Thermodynamic calculations using FactSage software were performed to explain these two key issues. In addition, an experimental study was performed to compare the melt cleanliness of the Ca-containing Mg alloys produced by the conventional route with metallic Ca and the ECO-Mg route with CaO.

Based on the Landset TM information of land use/cover change and greenbelt distribution in Hangzhou city in 1994 and 2004, and by using CITYgreen model, this paper estimated the eco-service value of urban greenbelt in the city under the effects of land use change and economic development. The results showed that in the 10 years from 1994 to 2004, the greenbelt area in the city decreased by 20. 4% , while its eco-service value increased by 168 million yuan. The annual increment of greenbelt eco-service value and GDP was 111.92% and 5. 32% , respectively. Suitable adjustment of land use pattern in the city harmonized the relationships between urban economic development and urban eco-function, and achieved higher eco-service efficiency of land utilization.

Full Text Available Mounting experimental and theoretical results indicate that neural systems are poised near a critical state. In human subjects, however, most evidence comes from functional MRI studies, an indirect measurement of neuronal activity with poor temporal resolution. Electrocorticography (ECoG provides a unique window into human brain activity: each electrode records, with high temporal resolution, the activity resulting from the sum of the local field potentials of sim 10^5 neurons. We show that the human brain ECoG recordings display features of self-regulated dynamical criticality: dynamical modes of activation drift around the critical stability threshold, moving in and out of the unstable region and equilibrating the global dynamical state at a very fast time scale. Moreover, the analysis also reveals differences between the resting state and a motor task, associated with increased stability of a fraction of the dynamical modes.

Chemical reactions and the combustion of dirty fuels, such as coal and petroleum coke (petcoke), that are used in cement production processes generate a significant amount of CO{sub 2} emissions. In this paper, we provide an eco-efficiency measure for 21 prototypes of cement industries operating in many countries by applying both a data envelopment analysis (DEA) and a directional distance function approach, which are particularly suitable for models where several production inputs and desirable and undesirable outputs are taken into account. To understand whether this eco-efficiency is due to a rational utilization of inputs or to a real carbon dioxide reduction as a consequence of environmental regulation, we analyze the cases where CO{sub 2} emissions can either be considered as an input or as an undesirable output. Empirical results show that countries where cement industries invest in technologically advanced kilns and adopt alternative fuels and raw materials in their production processes are eco-efficient. This gives a comparative advantage to emerging countries, such as India and China, which are incentivized to modernize their production processes.

2012-01-01

Ecological risks of heavy metals in urban soils were evaluated using Beijing, China as an example. Cadmium, Cu, Zn, Pb, Cr and Ni contents of 233 surface soils sampled by 1 min latitude × 1 min longitude grid were used to identify their spatial distribution patterns and potential emission sources. Throughout the city, longer the duration of urbanization greater was the accumulations of heavy metals especially, Cd, Cu, Pb, and Zn. The soil Zn mainly came from the wears of vehicular tires. Point source emissions of heavy metals were few and far in the downwind south–east quadrant of Beijing. The calculated risk indices showed potential median eco-risks in the ancient central city. No potential high eco-risk due to soil-borne heavy metals was found. The potential medium eco-risk areas in Beijing would expand from the initial 24 to 110 km 2 if soil pH were to reduce by 0.5 units in anticipation. - Highlights: ► Longer the time of urbanization, greater heavy metal accumulations were in the soils. ► Point source emissions of heavy metals are few in Beijing urban areas. ► The Zn enrichments in urban soils were caused by vehicle tires wearing. ► No high eco-risk areas were observed in Beijing. ► The decrease of soil pH will cause the expansion of medium eco-risk areas in Beijing. - Spatial distributions and potential eco-risks of soil-borne heavy metals in Beijing.

Full Text Available This work carries out the environmental evaluation of the cement production in Siguaney Factory as well as the calculation of the Eco-efficiency indicators according to the ISO 14045 norms; the Recipe methodology was used including 18 impact categories and the SimaPro 8.1 software was also used. In order to evaluate the eco-efficiency indicators according to the ISO 14045 norm, the results of the impact categories are related to the monetary value indicators, allowing the evaluation of the current situation as well as the consequences of the suggested modifications. As a result, the environmental profiles of P-35 cement (base case were obtained as well as those of the low carbon ones (LC3-35 y LC3-50 resulting from the clinker substitution by kaolinitic clay after some studies carried out by CIDEM researchers; and the eco-efficiency profiles. The comparison made between P-35 cement and the low-carbon cements showed positive results in eight weather impact categories, however, toxicity-related ones rise due to the increase in electricity consumption connected to the grinding of materials to obtain burnt clay bringing about a greater amount of emissions of volatile organic compounds to the air. An improvement in the eco-efficiency of 6 out of 8 calculated indicators is observed due to a simultaneous decrease in the production costs and the environmental impacts. LC3-50 cement shows the best results. The methodology used permits to evaluate alternatives related to the material substitution in the construction sector.

Form of an evolutionary tradeoff affects eco-evolutionary dynamics in a predator-prey system.

Kasada, Minoru; Yamamichi, Masato; Yoshida, Takehito

2014-11-11

Evolution on a time scale similar to ecological dynamics has been increasingly recognized for the last three decades. Selection mediated by ecological interactions can change heritable phenotypic variation (i.e., evolution), and evolution of traits, in turn, can affect ecological interactions. Hence, ecological and evolutionary dynamics can be tightly linked and important to predict future dynamics, but our understanding of eco-evolutionary dynamics is still in its infancy and there is a significant gap between theoretical predictions and empirical tests. Empirical studies have demonstrated that the presence of genetic variation can dramatically change ecological dynamics, whereas theoretical studies predict that eco-evolutionary dynamics depend on the details of the genetic variation, such as the form of a tradeoff among genotypes, which can be more important than the presence or absence of the genetic variation. Using a predator-prey (rotifer-algal) experimental system in laboratory microcosms, we studied how different forms of a tradeoff between prey defense and growth affect eco-evolutionary dynamics. Our experimental results show for the first time to our knowledge that different forms of the tradeoff produce remarkably divergent eco-evolutionary dynamics, including near fixation, near extinction, and coexistence of algal genotypes, with quantitatively different population dynamics. A mathematical model, parameterized from completely independent experiments, explains the observed dynamics. The results suggest that knowing the details of heritable trait variation and covariation within a population is essential for understanding how evolution and ecology will interact and what form of eco-evolutionary dynamics will result.

Eco-friendly or green dentistry can be a reality by effectively designing dental clinics and using more eco-friendly materials in the clinical practice. To determine the awareness of eco-friendly dentistry among dental faculty and students in preparation for future implementation. Assessment of knowledge regarding eco-friendly dentistry was done using an 18 item self-administered questionnaire among 160 participants. After baseline data collection, the intervention was done by educating participants with a power point presentation. The post-intervention data was then collected for analysis. Statistical analysis was done using Wilcoxon's signed rank test and one-way ANOVA. The educational intervention increased the knowledge about eco-friendly dentistry confirming the importance of continuing education. There was a statistically significant gain in knowledge among the participants after the presentation. The gain was highest for department of Preventive Dental Sciences (PDS) followed by Substitute Dental Sciences (SDS), No specialty, Maxillofacial Dental Sciences (MDS), and Restorative Dental Sciences (RDS) respectively. (F=5.5091, p<0.05). Lack of knowledge of green dentistry amongst the dental fraternity is highly prevailing. The same can be substantiated with effective training in the respective fields if channelized through the curriculum in an educational set-up.

Sustainable products become increasingly important for company in addressing eco-performance to satisfy global environmental regulations. Case study of flame guiding module reviewed design process and concerns related to the torch design. For enhancing flame height, the torch was embedded with an airflow guidance structure. The design process and design methodologies were investigated as an eco-design case study. Combine qualitative and CAE simulation were proposed to fulfil its main and auxiliary functions including reduction of impact during use. The design guidelines help prevent mistake arrangements, CAE helps understand combustion phenomenon. The flow field simulation enables fine tune of geometric design. Functional test and measurement are carried out to confirm the product features. On Eco-performance, we choose 5 items for evaluation the status of previous and redesign module, namely function need, low impact material, few manufacturing steps, low energy consumption, and safety. The radar diagram indicates that eco-performance of redesign module is better. Life cycle assessment calculated the carbon footprint of the manufacturing and processing stage with Eco-it. By using recycled steel in the flame module, it reduces raw material stage carbon footprint significantly.

The More, the Merrier: Why and How Employee-Driven Eco-Innovation Enhances Environmental and Competitive Advantage

Full Text Available Innovative solutions are often conjured as a key factor for companies to come closer to the goal of ecological sustainability. Furthermore, proactive eco-innovation activities can encompass competitive advantages. Companies are therefore well advised to tap any available source of innovation. However, although employees’ innovative capacity has often been described, to date, their manifold potentials for eco-innovation processes have hardly been examined in detail. The overarching research questions guiding this conceptual paper are why and how employee participation in eco-innovation processes can entail environmental and competitive advantages for companies. The authors introduce the concept of employee-driven eco-innovation (EDEI, defined here as ordinary employees’ voluntary engagement in innovation activities within an organizational context that, intentionally or not, lead to environmental improvements. This paper complements previous literature on employee-driven innovation (EDI by applying it to the specific case of eco-innovation. In this context, employees’ comprehensive environmental competences resulting from “tacit knowledge”, “private consumer experience” and “green identity” are taken into account. In addition, we delineate critical intra-organizational factors for EDEI activities and illustrate green employees’ specific requirements in this regard.

2013-12-17

Ecologically based life cycle assessment (Eco-LCA) is an appealing approach for the evaluation of resources utilization and environmental impacts of the process industries from an ecological scale. However, the aggregated metrics of Eco-LCA suffer from some drawbacks: the environmental impact metric has limited applicability; the resource utilization metric ignores indirect consumption; the renewability metric fails to address the quantitative distinction of resources availability; the productivity metric seems self-contradictory. In this paper, the existing Eco-LCA metrics are revised and extended for sustainability assessment of the energy and chemical processes. A new Eco-LCA metrics system is proposed, including four independent dimensions: environmental impact, resource utilization, resource availability, and economic effectiveness. An illustrative example of comparing assessment between a gas boiler and a solar boiler process provides insight into the features of the proposed approach.

Functions that Protect Escherichia coli from Tightly Bound DNA-Protein Complexes Created by Mutant EcoRII Methyltransferase.

Expression of mutant EcoRII methyltransferase protein (M.EcoRII-C186A) in Escherichia coli leads to tightly bound DNA-protein complexes (TBCs), located sporadically on the chromosome rather than in tandem arrays. The mechanisms behind the lethality induced by such sporadic TBCs are not well studied, nor is it clear whether very tight binding but non-covalent complexes are processed in the same way as covalent DNA-protein crosslinks (DPCs). Using 2D gel electrophoresis, we found that TBCs induced by M.EcoRII-C186A block replication forks in vivo. Specific bubble molecules were detected as spots on the 2D gel, only when M.EcoRII-C186A was induced, and a mutation that eliminates a specific EcoRII methylation site led to disappearance of the corresponding spot. We also performed a candidate gene screen for mutants that are hypersensitive to TBCs induced by M.EcoRII-C186A. We found several gene products necessary for protection against these TBCs that are known to also protect against DPCs induced with wild-type M.EcoRII (after 5-azacytidine incorporation): RecA, RecBC, RecG, RuvABC, UvrD, FtsK, XerCD and SsrA (tmRNA). In contrast, the RecFOR pathway and Rep helicase are needed for protection against TBCs but not DPCs induced by M.EcoRII. We propose that stalled fork processing by RecFOR and RecA promotes release of tightly bound (but non-covalent) blocking proteins, perhaps by licensing Rep helicase-driven dissociation of the blocking M.EcoRII-C186A. Our studies also argued against the involvement of several proteins that might be expected to protect against TBCs. We took the opportunity to directly compare the sensitivity of all tested mutants to two quinolone antibiotics, which target bacterial type II topoisomerases and induce a unique form of DPC. We uncovered rep, ftsK and xerCD as novel quinolone hypersensitive mutants, and also obtained evidence against the involvement of a number of functions that might be expected to protect against quinolones.

2011-07-01

Full Text Available Drought, floods, damaging storms, heat waves, acid rain, climate changes are but a few of the consequences of human action upon the environment. Can we possibly live against the environment? The answer is NO, and as such we must run an economy which respects the principles of eco-efficiency because only so can economic progress go on. Green economy is a great opportunity for all of the world’s countries, and is a real economy which keeps the resource-needs and environment relation in balance, aims towards quality and not quantity, lays emphasis on regeneration, recycling, reuse and creativity. Eco-efficiency implies both innovation towards a high degree of product dematerialization, services and systems, alongside with greatly changing current production and consumption practices. If we produce based on the principle of eco-efficiency we can reduce the effects of the profound economic, ecological, socio-political and cultural-spiritual crisis which marks our planet and countries.

Eco's Echoes: Fictional Theory and Detective Practice in The Name of the Rose

David H. Richter

1986-01-01

Full Text Available Umberto Eco's The Name of the Rose is a serio-comic pastiche of the detective story set in the middle ages, which uses history as "a distant mirror" to comment, from a Western Marxist perspective, on contemporary political issues. Structurally, however, The Name of the Rose is a fictional enactment of many of the semiotician's recent critical and philosophical ideas. ( 1 Eco's discussion of "abductive" reasoning in C. S. Peirce and Aristotle appears in a detective not only more fallible than Sherlock Holmes but more aware of what his powers consist of and why they work and fail. (2 Eco's explanation of what he calls the "iterative scheme" in popular fiction—ways of handling time that allow for indefinite sequelae —appears negatively here, where time and time's passage are given their full durational weight. (3 Eco's discussion of closed and open texts, and of a third category "of which the chairman is probably Tristram Shandy ," which evades both modes of reading and forces one into consciousness of the reading process itself, is enacted in The Name of the Rose , in a traditionally closed genre (the mystery which is first opened but finally given an ending that deconstructs the mystery novel by forcing the reader into the third, Shandean, mode.

Life Cycle Assessment of Process Eco-Innovations in an SME Automotive Supply Network

Alberto Simboli

2015-10-01

Full Text Available The aim of the study presented in this article is to assess, from an environmental standpoint, a set of eco-innovations applied to the production process of an automotive component. The eco-innovations were developed by a supply network of small- and medium-sized enterprises (SMEs in the framework of a project named “Hi-reach”. The component considered is a motorcycle rear wheel spindle. The conventional version is obtained by machining a single forged steel part. The Hi-reach version is indeed manufactured by joining a shaft to a flange; in addition, conventional surface treatments are replaced by a plasma-enhanced chemical vapour deposition (PECVD treatment and other machining steps are improved. This process was conceived with the aim of maintaining (or enhancing the technical performance of the spindle and reducing production costs. A Life Cycle Assessment (LCA was carried out to compare the two scenarios described. Those eco-innovations resulted in significant improvements of the environmental performance of the analysed component, ranging, on average, between 50% and 70% for the impact indicators considered. Our results also highlight the role of SMEs in promoting process eco-innovations and the increasing relevance of LCA as a tool to support decision making in manufacturing.

Interaction between an Eco-Spiral Bolt and Crushed Rock in a Borehole Evaluated by Pull-Out Testing

Directory of Open Access Journals (Sweden)

Seong-Seung Kang

2017-01-01

Full Text Available The interactions between an eco-spiral bolt and crushed rocks in a borehole were evaluated by pull-out testing in a laboratory and numerical analysis. The porosity of the crushed rock surrounding the bolt depended on the size of the eco-spiral bolt and affected the eco-spiral bolt’s axial resistance force. The axial resistance force and the porosity of the crushed rocks in the borehole showed an inverse relationship. The porosity was also related to the size of the eco-spiral bolt. The maximum principal stress between the bolt and the rock was related to the porosity of the crushed rock and the size difference between the eco-spiral bolt and the borehole. At low porosity the experimental and numerical analyses show similar relationships between the axial resistance force and the displacement. However, at high porosity, the numerical results deviated greatly from the experimental observation. The initial agreement is attributed to the state of residual resistance after the maximum axial resistance force, and the latter divergence was due to the decreasing axial resistance force owing to slippage.

Maja Fredotović

2011-02-01

Full Text Available Tourism is extremely interacted with the environment. Taking into account that tourism uses the space and related resources, it seems right to pay for the damages caused to the environment. This is the basis of the tourist spatial eco rent. The paper evaluates the space and resources used by tourism as the basis for the introduction of the tourism eco-rent in the area of Makarska Riviera, a traditional tourism destination. It is divided into three main spatial units: urban areas, bathing zone (beaches, Biokovo Park of Nature. According to natural and geographical reasoning, a number of zones with different spatial values within each spatial unit has been identified. Each unit, i.e. zone was evaluated according to various criteria relevant to the evaluation of space for tourism and tourism development purposes. Having ranked zones within each unit, using the multiriteria ranking method PROMETHEE II, comparative analysis of the obtained results was carried out as well.

THE ROLE OF ECO-INNOVATION IN THE ENERGY

Aleksandra Kokić Arsić

2009-09-01

Full Text Available The immediate effect of energy consumption on environment quality is its deterioration. Gas and dust emissions, as products of coal, mazut (heavy fuel oil or natural gas combustion, continually pollute the atmosphere and have a global effect on climate changes, ozone damage, acid rains, disappearing of sensitive ecosystems, etc. This, directly or indirectly, brings about pollution of soil and fresh water, since energy life cycle begins with mines, oil and gas deposits, and ends with mechanical operations, heating and cooling with the restoration of thermal energy back into the atmosphere. In order to anticipate these negative processes, it is necessary to conduct an array of eco innovations in the entire life cycle of final energy. What this paper will show, on the example of communally-industrial energetics, is methodology of research and realization of eco innovations, as well as assessment of effects on improvement of energetic efficiency, quality of the environment and human life.

2016-01-01

Highlights: • Systematic approach to eco-design of steam turbine rotor blades was applied. • Eco-innovative solutions are based on structural and technological change. • At the stage of detailed design the variants were analyzed using LCA. • Main achieved benefits: energy and material savings, lower environmental impact. • Benefits related to the possible scale of the solution practical application. - Abstract: Eco-design of steam turbine blades could be one of the possibilities of decreasing the environmental impact of energy systems based on turbines. The paper investigates the eco-design approach to elaboration of the rotor blades and packages. The purpose is to present the course of eco-design of the rotor blades and the rotor packages taking account of eco-design assumptions, solutions and the concept itself. The following eco-design variants of the rotor blades and the rotor packages are considered: elements of the rotor blades made separately (baseline variant of the rotor blades); elements of the rotor blades made of one piece of material; blades in packages made separately and welded (baseline variant of the rotor packages); packages milled as integral elements. At the stage of detailed design, the Life Cycle Assessment (LCA) is performed in relation to a functional unit – the rotor blades and packages ready for installation in a steam turbine, which is the stage of the turbine. The obtained results indicate that eco-innovative solutions for the turbine blades and packages could be achieved through structural and technological changes. Applying new solutions of the rotor blades may produce the following main benefits: 3.3% lower use of materials, 29.4% decrease in energy consumption at the manufacturing stage, 7.7% decrease in the environmental impact in the life cycle. In relation to the rotor packages, the following main benefits may be achieved: 20.5% lower use of materials, 25.0% decrease in energy consumption at the production stage, 16

A piecewise probabilistic regression model to decode hand movement trajectories from epidural and subdural ECoG signals

Farrokhi, Behraz; Erfanian, Abbas

2018-06-01

Objective. The primary concern of this study is to develop a probabilistic regression method that would improve the decoding of the hand movement trajectories from epidural ECoG as well as from subdural ECoG signals. Approach. The model is characterized by the conditional expectation of the hand position given the ECoG signals. The conditional expectation of the hand position is then modeled by a linear combination of the conditional probability density functions defined for each segment of the movement. Moreover, a spatial linear filter is proposed for reducing the dimension of the feature space. The spatial linear filter is applied to each frequency band of the ECoG signals and extract the features with highest decoding performance. Main results. For evaluating the proposed method, a dataset including 28 ECoG recordings from four adult Japanese macaques is used. The results show that the proposed decoding method outperforms the results with respect to the state of the art methods using this dataset. The relative kinematic information of each frequency band is also investigated using mutual information and decoding performance. The decoding performance shows that the best performance was obtained for high gamma bands from 50 to 200 Hz as well as high frequency ECoG band from 200 to 400 Hz for subdural recordings. However, the decoding performance was decreased for these frequency bands using epidural recordings. The mutual information shows that, on average, the high gamma band from 50 to 200 Hz and high frequency ECoG band from 200 to 400 Hz contain significantly more information than the average of the rest of the frequency bands ≤ft( pright) for both subdural and epidural recordings. The results of high resolution time-frequency analysis show that ERD/ERS patterns in all frequency bands could reveal the dynamics of the ECoG responses during the movement. The onset and offset of the movement can be clearly identified by the ERD/ERS patterns. Significance

Certifying the commons: eco-certification, privatization, and collective action

Directory of Open Access Journals (Sweden)

Paul Foley

2014-06-01

Full Text Available We examine new dynamics of privatization and collective action in common pool resource situations facilitated by the nonstate multistakeholder institutions of the Marine Stewardship Council (MSC, the global leader in sustainability certification for wild caught seafood. Through a review of the literature and two case studies of fishing cooperatives in Baja California Sur, Mexico and on Fogo Island in the Canadian Province of Newfoundland and Labrador (NL, we advance two interrelated arguments. First, certification and eco-labeling institutions privatize fisheries governance in largely unexamined ways through the injection of new forms of exclusive rights or privileges into common pool resource situations already complicated by access and property privileges, creating conditions for confusion and conflict as well as cooperation. Second, the MSC whole stock definition of sustainability places greater demands on certification clients for engaging in collective action by encouraging coordination over all social extractions from targeted fish stocks. Although rules encouraging collective action in common pool situations militate against the narrow private capture of certificate and eco-label rights, they also undermine the ability of small-scale and community-based fisheries that are embedded in larger unhealthy fishery contexts to acquire the right to the MSC stamp of sustainability. We conclude that MSC certification and eco-labeling create new institutions of private property rights and collective action, which can result in exclusionary practices, inclusionary collective action, or both. Much will depend on the specific common pool context and history of the fishery.

Paula Escribano

2017-12-01

Full Text Available Studying grassroots initiatives which aim to respond to environmental and social crisis is of renewed importance nowadays, in the aftermath of the 2008-9 financial crisis in southern Europe. This paper studies people’s motivations for becoming part of an eco-community in Catalonia, Spain, through interviews with 29 informants. The research is part of a larger study, based on ethnographic data collected between 2013 and 2015 in 27 eco-communities. The paper shows the extent to which people who joined an eco-community were driven by ideological reasons, adopting a livelihood strategy, or by a combination of both factors in the years following the crisis. We argue that the social and economic crisis has had an impact on the factors motivating people to join these communities, with an increase in the number of people driven by materialistic motives, relative to those who joined for ideological reasons.

Localizing ECoG electrodes on the cortical anatomy without post-implantation imaging

Science.gov (United States)

Gupta, Disha; Hill, N. Jeremy; Adamo, Matthew A.; Ritaccio, Anthony; Schalk, Gerwin

2014-01-01

Introduction Electrocorticographic (ECoG) grids are placed subdurally on the cortex in people undergoing cortical resection to delineate eloquent cortex. ECoG signals have high spatial and temporal resolution and thus can be valuable for neuroscientific research. The value of these data is highest when they can be related to the cortical anatomy. Existing methods that establish this relationship rely either on post-implantation imaging using computed tomography (CT), magnetic resonance imaging (MRI) or X-Rays, or on intra-operative photographs. For research purposes, it is desirable to localize ECoG electrodes on the brain anatomy even when post-operative imaging is not available or when intra-operative photographs do not readily identify anatomical landmarks. Methods We developed a method to co-register ECoG electrodes to the underlying cortical anatomy using only a pre-operative MRI, a clinical neuronavigation device (such as BrainLab VectorVision), and fiducial markers. To validate our technique, we compared our results to data collected from six subjects who also had post-grid implantation imaging available. We compared the electrode coordinates obtained by our fiducial-based method to those obtained using existing methods, which are based on co-registering pre- and post-grid implantation images. Results Our fiducial-based method agreed with the MRI–CT method to within an average of 8.24 mm (mean, median = 7.10 mm) across 6 subjects in 3 dimensions. It showed an average discrepancy of 2.7 mm when compared to the results of the intra-operative photograph method in a 2D coordinate system. As this method does not require post-operative imaging such as CTs, our technique should prove useful for research in intra-operative single-stage surgery scenarios. To demonstrate the use of our method, we applied our method during real-time mapping of eloquent cortex during a single-stage surgery. The results demonstrated that our method can be applied intra

The large-scale and super-strength development of mineral resources in mining cities in long term has made great contributions to China's economic construction and development, but it has caused serious damage to the ecological environment even ecological imbalance at the same time because the neglect of the environmental impact even to the expense of the environment to some extent. In this study, according to the characteristics of mining cities, the scientific and practical eco-environmental vulnerability evaluation index system of mining cities had been established. Taking Panzhihua city of Sichuan province as an example, using remote sensing and GIS technology, applying various types of remote sensing image (TM, SPOT5, IKONOS) and Statistical data, the ecological environment evaluation data of mining cities was extracted effectively. For the non-linear relationship between the evaluation indexes and the degree of eco-environmental vulnerability in mining cities, this study innovative took the evaluation of eco-environmental vulnerability of the study area by using artificial neural network whose training used SCE-UA algorithm that well overcome the slow learning and difficult convergence of traditional neural network algorithm. The results of ecoenvironmental vulnerability evaluation of the study area were objective, reasonable and the credibility was high. The results showed that the area distribution of five eco-environmental vulnerability grade types was basically normal, and the overall ecological environment situation of Panzhihua city was in the middle level, the degree of eco-environmental vulnerability in the south was higher than the north, and mining activities were dominant factors to cause ecoenvironmental damage and eco-environmental Vulnerability. In this study, a comprehensive theory and technology system of regional eco-environmental vulnerability evaluation which included the establishment of eco-environmental vulnerability evaluation index

A GIS-based decision support system for regional eco-security assessment and its application on the Tibetan Plateau.

Science.gov (United States)

Xiaodan, Wang; Xianghao, Zhong; Pan, Gao

2010-10-01

Regional eco-security assessment is an intricate, challenging task. In previous studies, the integration of eco-environmental models and geographical information systems (GIS) usually takes two approaches: loose coupling and tight coupling. However, the present study used a full coupling approach to develop a GIS-based regional eco-security assessment decision support system (ESDSS). This was achieved by merging the pressure-state-response (PSR) model and the analytic hierarchy process (AHP) into ArcGIS 9 as a dynamic link library (DLL) using ArcObjects in ArcGIS and Visual Basic for Applications. Such an approach makes it easy to capitalize on the GIS visualization and spatial analysis functions, thereby significantly supporting the dynamic estimation of regional eco-security. A case study is presented for the Tibetan Plateau, known as the world's "third pole" after the Arctic and Antarctic. Results verified the usefulness and feasibility of the developed method. As a useful tool, the ESDSS can also help local managers to make scientifically-based and effective decisions about Tibetan eco-environmental protection and land use. Copyright (c) 2010 Elsevier Ltd.

Challenges for eco-design of emerging technologies: The case of electronic textiles

International Nuclear Information System (INIS)

Köhler, Andreas R.

2013-01-01

Highlights: • Recent innovations of electronic textiles and their end-of-life impacts are reviewed. • The properties of e-textiles are examined against Design for Recycling (DfR) principles. • Eco-design strategies for sustainable product development are discussed. • Compatibility standards for e-textiles are proposed as a waste prevention strategy. • Labelling of e-textiles is suggested as a measure to facilitate recycling. - Abstract: The combination of textile and electronic technologies results in new challenges for sustainable product design. Electronic textiles (e-textiles) feature a seamless integration of textiles with electronics and other high-tech materials. Such products may, if they become mass consumer applications, result in a new kind of waste that could be difficult to recycle. The ongoing innovation process of e-textiles holds opportunities to prevent future end-of-life impacts. Implementing eco-design in the technological development process can help to minimise future waste. However, the existing Design for Recycling (DfR) principles for textiles or electronics do not match with the properties of the combined products. This article examines possibilities to advance eco-design of a converging technology. DfR strategies for e-textiles are discussed from the background of contemporary innovation trends. Three waste preventative eco-design approaches for e-textiles are discussed: 1 harnessing the inherent advantages of smart materials for sustainable design; 2 establishing open compatibility standards; 3 labelling the e-textiles to facilitate their recycling. It is argued that life-cycle thinking needs to be implemented concurrent to the technological development process

2011-12-01

The Jinghe River Basin is one of the most serious soil erosion areas in the Loess Plateau. Many measures of soil and water conservation were applied in the basin. Terrestrial ecosystem model BIOME-BGC and distributed hydrological model WEP-L were used to build eco-hydrological model and verified by field observation and literature values. The model was applied in the Jinghe River Basin to analyze eco-hydrological responses under the scenarios of vegetation type change due to soil and water conservation polices. Four scenarios were set under the measures of conversion of cropland to forest, forestation on bare land, forestation on slope wasteland and planting grass on bare land. Analysis results show that the soil and water conservation has significant effects on runoff and the carbon cycle in the Jinghe River Basin: the average annual runoff would decrease and the average annual NPP and carbon storage would increase. Key words: soil and water conservation; conversion of cropland to forest; eco-hydrology response; the Jinghe River Basin

Eco taxes and double dividend. A co-integration analysis

1999-01-01

The paper tackles with the critical discussion of the eco tax double dividend theory. It is built up a theoretical and empirical analysis on short and long run effects of changes in real prices of energetic inputs on the use of polluted sources and labour, as well as on short and long run effects of changes in real labour cost on the use of labour and energy. At that purpose Johansen's procedure allows to get a structural multivariate model of dynamic relationships among the variables enclosed in the data set of a production function with labour and energy. This model is submitted to a dynamic simulation and results suggest that the introduction of an eco tax coupled with a decreasing in real labour cost would have uncertain and not leasing effects on the reduction of pollution coming from the utilisation of energetic sources and very limited effects on employment [it

Recent years have shown a marked interest in the construction of eco-towns, showcase developments intended to demonstrate the best in ecologically-sensitive and energy-efficient construction. This paper examines one such development in the UK and considers the role of biomass energy systems. We present an integrated resource modelling framework that identifies an optimized low-cost energy supply system including the choice of conversion technologies, fuel sources, and distribution networks. Our analysis shows that strategies based on imported wood chips, rather than locally converted forestry residues, burned in a mix of ICE and ORC combined heat and power facilities offer the most promise. While there are uncertainties surrounding the precise environmental impacts of these solutions, it is clear that such biomass systems can help eco-towns to meet their target of an 80% reduction in greenhouse gas emissions. -- Highlights: ► An optimization model for urban biomass energy system design is presented. ► Tool selects technologies, operating rates, supply infrastructures. ► Five technology scenarios evaluated for a UK eco-town proposal. ► Results show ICE and ORC CHP units, fed by wood chips, promising. ► Results show biomass can help eco-towns achieve 80% GHG emission reductions.

Amiri, Mohammad C.; Mohammadifard, Hossein; Ghaffari, Ghasem

2016-07-01

Purpose - Water scarcity will further stress on available water systems and decrease the security of water in many areas. Therefore, innovative methods to minimize industrial water usage and waste production are of paramount importance in the process of extending fresh water resources and happen to be the main life support systems in many arid regions of the world. This paper demonstrates that there are good opportunities for many industries to save water and decrease waste water in softening process by substituting traditional with echo-friendly methods. The patented puffing method is an eco-efficient and viable technology for water saving and waste reduction in lime softening process. Design/methodology/approach - Lime softening process (LSP) is a very sensitive process to chemical reactions. In addition, optimal monitoring not only results in minimizing sludge that must be disposed of but also it reduces the operating costs of water conditioning. Weakness of the current (regular) control of LSP based on chemical analysis has been demonstrated experimentally and compared with the eco-efficient puffing method. Findings - This paper demonstrates that there is a good opportunity for many industries to save water and decrease waste water in softening process by substituting traditional method with puffing method, a patented eco-efficient technology. Originality/value - Details of the required innovative works to minimize industrial water usage and waste production are outlined in this paper. Employing the novel puffing method for monitoring of lime softening process results in saving a considerable amount of water while reducing chemical sludge.

Consumer Choices and Motives for Eco-Labeled Products in China: An Empirical Analysis Based on the Choice Experiment

Directory of Open Access Journals (Sweden)

Qing Liu

2017-02-01

Full Text Available Based on choice experiments conducted via face-to-face interviews with 435 participants in four provincial areas of China (Shanghai, Zhejiang, Jiangsu, and Guangdong, Chinese consumers’ preferences and motives for purchasing eco-labeled rice are examined in this study. The heterogeneous effects of each motivating channel are also investigated. The results reveal positive correlations between premiums for eco-labeled rice and consumers’ concerns about food safety and the environment, suggesting that health benefits and environmental considerations are the two critical motivations. The willingness to pay for eco-labeled rice does not increase with consumers’ knowledge of the different production standards indicated by each eco-label. Individual characteristics that determine each class are further explored through a seemingly irrelevant regression to identify the target group of consumers for policy-makers.

Eco-Labeling and Retailer Pricing Strategies: The U.K. Haddock Market

Directory of Open Access Journals (Sweden)

Dengjun Zhang

2018-05-01

Full Text Available In attempts to differentiate their store imagery, grocery retailers frequently introduce new products, which are often rich in extrinsic attributes such as claims regarding healthiness and environmental sustainability. This paper explores retailers’ pricing strategies for product attributes of haddock in the United Kingdom. The results show that retailers’ pricing strategies vary, in particular for extrinsic product attributes such as eco-labels and country-of-origin. The high price premium generated from the most advocated eco-labels and an emphasis upon promotion strategies appear to play a role in the success of high-end retailers, and may have implications for any heightened competitive responses by larger retail chains in the future.

ECO: A Framework for Entity Co-Occurrence Exploration with Faceted Navigation

Energy Technology Data Exchange (ETDEWEB)

Halliday, K. D. [Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States)

2010-08-20

Even as highly structured databases and semantic knowledge bases become more prevalent, a substantial amount of human knowledge is reported as written prose. Typical textual reports, such as news articles, contain information about entities (people, organizations, and locations) and their relationships. Automatically extracting such relationships from large text corpora is a key component of corporate and government knowledge bases. The primary goal of the ECO project is to develop a scalable framework for extracting and presenting these relationships for exploration using an easily navigable faceted user interface. ECO uses entity co-occurrence relationships to identify related entities. The system aggregates and indexes information on each entity pair, allowing the user to rapidly discover and mine relational information.

Anh, N. K.; Liou, Y. A.; Li, M. H.

The motivation for this study is assessment of the eco-environment vulnerability based on four independent determinants: hydro-meteorology, topography, land resources, and human activities. An assessment framework is proposed to assess the vulnerable eco-environment by using 16 variables with 6 of them constructed from Landsat 8 satellite images. The remaining variables were extracted from digital maps. Each variable was evaluated and spatially mapped with the aid of an analytical hierarchy process (AHP) and geographical information system (GIS). The Thua Thien - Hue Province that has been experiencing natural disasters and urbanization in the recent decades is selected as our study area. An eco-environmental vulnerability map is assorted into six vulnerable levels consisting of potential, slight, light, medium, heavy, and very heavy vulnerabilities, representing 14%, 27%, 17%, 26%, 13%, 3% of the study area, respectively. It is found that heavy and very heavy vulnerable areas appear mainly in the low and medium lands with high intensification of social-economic activities and often suffer from flooding. Tiny percentages of medium and heavy vulnerable levels occur in high land areas probably caused by agricultural practices in highlands, slash and burn cultivation and removal of natural forests with new plantation forests and these regions are usually influenced by landslides, flash flooding. Based on our results, three ecological zones requiring different development and protection solutions are proposed to restore local eco-environment toward sustainable development. Our findings support the idea that eco-environmental vulnerability is driven by anthropogenic processes and enhanced by natural disaster in the Thua Thien-Hue Province.

Full Text Available Implementation of the development is often cause adverse environmental impacts. Adverse effects are environmental degradation and decreasing availability of resources. To overcome this, it is necessary that the development can still continue, the environment is not damaged, and the availability of resources is maintained. One effort is through eco - economic decoupling activities with the use of spent resources. The aim of study to determine the potential of spent resources in Central Java, knows the problems in the utilization of spent resources in Central Java, and to determine the impact of the utilization of spent resources in Central Java by a qualitative descriptive method. The results show that in the study have the potential of eco-economic decoupling indicated by the availability of spent resources and had done utilization of spent resources. However, this potential has not been optimally developed, because there are still some problems in its utilization. Problems in the use of spent resources are the lack of knowledge about eco-economic decoupling and spent resources among stakeholder, there is no specific policy on eco - economic decoupling, the lack of Local Government 's role in the utilization of spent resource, and the lack of synergy programs and activities in supporting the utilization of spent resources. Utilization of spent resources have positive impact to reduce pressure on the environment and natural resources, create a new job, and increase incomes for society.

Assessing eco-efficiency and the determinants of horticultural family-farming in southeast Spain.

Godoy-Durán, Ángeles; Galdeano-Gómez, Emilio; Pérez-Mesa, Juan C; Piedra-Muñoz, Laura

2017-12-15

Eco-efficiency is currently receiving ever increasing interest as an indicator of sustainability, as it links environmental and economic performances in productive activities. In agriculture these indicators and their determinants prove relevant due to the close ties in this activity between the use of often limited natural resources and the provision of basic goods for society. The present paper analyzes eco-efficiency at micro-level, focusing on small-scale family farms as the principal decision-making units (DMUs) of horticulture in southeast Spain, which represents over 30% of fresh vegetables produced in the country. To this end, Data Envelopment Analysis (DEA) framework is applied, computing several combinations of environmental pressures (water usage, phytosanitary contamination, waste management, etc.) and economic value added. In a second stage we analyze the influence of family farms' socio-economic and environmental features on eco-efficiency indicators, as endogenous variables, by using truncated regression and bootstrapping techniques. The results show major inefficiency in aspects such as waste management, among others, while there is relatively minor inefficiency in water usage and nitrogen balance. On the other hand, features such as product specialization, adoption of quality certifications, and belonging to a cooperative all have a positive influence on eco-efficiency. These results are deemed to be of interest to agri-food systems structured on small-scale producers, and they may prove useful to policy-makers as regards managing public environmental programs in agriculture.

Spatial co-adaptation of cortical control columns in a micro-ECoG brain-computer interface

Science.gov (United States)

Rouse, A. G.; Williams, J. J.; Wheeler, J. J.; Moran, D. W.

2016-10-01

Objective. Electrocorticography (ECoG) has been used for a range of applications including electrophysiological mapping, epilepsy monitoring, and more recently as a recording modality for brain-computer interfaces (BCIs). Studies that examine ECoG electrodes designed and implanted chronically solely for BCI applications remain limited. The present study explored how two key factors influence chronic, closed-loop ECoG BCI: (i) the effect of inter-electrode distance on BCI performance and (ii) the differences in neural adaptation and performance when fixed versus adaptive BCI decoding weights are used. Approach. The amplitudes of epidural micro-ECoG signals between 75 and 105 Hz with 300 μm diameter electrodes were used for one-dimensional and two-dimensional BCI tasks. The effect of inter-electrode distance on BCI control was tested between 3 and 15 mm. Additionally, the performance and cortical modulation differences between constant, fixed decoding using a small subset of channels versus adaptive decoding weights using the entire array were explored. Main results. Successful BCI control was possible with two electrodes separated by 9 and 15 mm. Performance decreased and the signals became more correlated when the electrodes were only 3 mm apart. BCI performance in a 2D BCI task improved significantly when using adaptive decoding weights (80%-90%) compared to using constant, fixed weights (50%-60%). Additionally, modulation increased for channels previously unavailable for BCI control under the fixed decoding scheme upon switching to the adaptive, all-channel scheme. Significance. Our results clearly show that neural activity under a BCI recording electrode (which we define as a ‘cortical control column’) readily adapts to generate an appropriate control signal. These results show that the practical minimal spatial resolution of these control columns with micro-ECoG BCI is likely on the order of 3 mm. Additionally, they show that the combination and

Objective. Innovations in micro-electrocorticography (µECoG) electrode array manufacturing now allow for intricate designs with smaller contact diameters and/or pitch (i.e. inter-contact distance) down to the sub-mm range. The aims of the present study were: (i) to investigate whether frequency ranges up to 400 Hz can be reproducibly observed in µECoG recordings and (ii) to examine how differences in topographical substructure between these frequency bands and electrode array geometries can be quantified. We also investigated, for the first time, the influence of blood vessels on signal properties and assessed the influence of cortical vasculature on topographic mapping. Approach. The present study employed two µECoG electrode arrays with different contact diameters and inter-contact distances, which were used to characterize neural activity from the somatosensory cortex of minipigs in a broad frequency range up to 400 Hz. The analysed neural data were recorded in acute experiments under anaesthesia during peripheral electrical stimulation. Main results. We observed that µECoG recordings reliably revealed multi-focal cortical somatosensory response patterns, in which response peaks were often less than 1 cm apart and would thus not have been resolvable with conventional ECoG. The response patterns differed by stimulation site and intensity, they were distinct for different frequency bands, and the results of functional mapping proved independent of cortical vascular. Our analysis of different frequency bands exhibited differences in the number of activation peaks in topographical substructures. Notably, signal strength and signal-to-noise ratios differed between the two electrode arrays, possibly due to their different sensitivity for variations in spatial patterns and signal strengths. Significance. Our findings that the geometry of µECoG electrode arrays can strongly influence their recording performance can help to make informed decisions that maybe

Research highlights: → Successful fusion of GFP to M.EcoKI DNA methyltransferase. → GFP located at C-terminal of sequence specificity subunit does not later enzyme activity. → FRET confirms structural model of M.EcoKI bound to DNA. -- Abstract: We describe the fusion of enhanced green fluorescent protein to the C-terminus of the HsdS DNA sequence-specificity subunit of the Type I DNA modification methyltransferase M.EcoKI. The fusion expresses well in vivo and assembles with the two HsdM modification subunits. The fusion protein functions as a sequence-specific DNA methyltransferase protecting DNA against digestion by the EcoKI restriction endonuclease. The purified enzyme shows Foerster resonance energy transfer to fluorescently-labelled DNA duplexes containing the target sequence and to fluorescently-labelled ocr protein, a DNA mimic that binds to the M.EcoKI enzyme. Distances determined from the energy transfer experiments corroborate the structural model of M.EcoKI.

Based on the assessment method of environmental vulnerability constructed by SOPAC and UNEP, this paper constructed an indicator system from three sub-themes including hazard, resistance, and damage to assess the eco-environmental vulnerability of Hainan Island. The results showed that Hainan Island was suffering a middling level eco-environmental hazard, and the main hazards came from some intensive human activities such as intensive agriculture, mass tourism, mining, and a mass of solid wastes thrown by islanders and tourists. Some geographical characters such as larger land area, larger altitude range, integrated geographical form, and abundant habitat types endowed Hainan Island higher resistance to environmental hazards. However, disturbed by historical accumulative artificial and natural hazards, the Island ecosystem had showed serious ecological damage, such as soil degradation and biodiversity loss. Comprehensively considered hazard, resistance, damage, and degradation, the comprehensive environmental vulnerability of the Island was at a middling level. Some indicators showed lower vulnerability, but some showed higher vulnerability.

[Impact of hypoxia in different periods of prenatal ontogenesis on ECoG of rabbit fetus].

Guseĭnov, A G; Mamedov, Kh B

2012-10-01

Sensitivity of ECoG of sensorimotor cortex of 28-day rabbit foetus in different periods (prefetal and fetal) of embryogenesis to hypoxia impact was studied. In the foetus subjected to hypoxia during prefetal period (8-18th days) in the spectrum of the general activity the increase of slow waves, occupying little portion of the spectrum, is noticed, while the main delta-rhythm has more clear pattern. At the same time, hypoxia, undertaken in the fetal period (18-28th days) does not have significant effect on ECoG indexes. On the basis of our own and literature data one can propose tha high sensitivity of ECoG to oxygen deficiency is due to low stability of the brain cortex itself and subcortical white matter to hypoxic inpairement in early embriogenesis.

Most teachers stop on the most important sources, sources of knowledge that young learners can turn to and would be better to turn. They indicate written sources, books, magazines and other publications available in classical libraries and add, especially now, the world’s largest library: the Internet. However, teachers advise students to seek permanently another source, a "book" - permanently opened, the book of reality that contains the most truth and what is very important - many problems waiting to be discovered and resolved. Leafing over "the first pages" of one of the "volumes" of this huge established "book", I found that the paradigm "Everything moves. Nothing stands still" as the paradigm "movement is absolute, and the repose - roughly" is far from having exhausted full knowledge of "everything".

Natural dyes represent an emerging trend in the textile industry and eco-fashion due to the increasing awareness of the sustainability concept, which must be applied to the surrounding environment. In the light of the stated problem, the search for alternative sources of dyes, revealed the new, eco-friendly, biodegradable, non-carcinogenic and sustainable colorant matter, the algal biomass. In the present work, the suitability and viability of printing cotton fabrics with pigments obtained from the red macroalgae Gracilaria sp., has been investigated. For this aim, phycoerythrin, the red pigment, was extracted from fresh algal biomass, and used in a laboratory pigment-printing process, employing a natural and synthetic printing paste, for process efficiency comparison. The color values and the rubbing and laundering fastness of the printed substrates were evaluated. Results show that a light pink color can be obtained when applying both tested printing processes, and in terms of color fastness, both printing pastes show good behavior. In conclusion, the algal pigments show a high printing capacity on cotton substrates, either when employing the synthetic conventional paste and; moreover, when applying the more sustainable and eco-friendly natural paste.

Eco-driving behavior can be triggered by many aspects such as economic and environmental awareness. In Indonesia this issue received less attention from citizen, whereas it has significant roles in reducing greenhouse gas emission. This paper initiated a study about eco-driving tendency behavior among Indonesian people, the objective is to see whether current behavior support or not, and does the differences between gender and age exist. Adopted on-line study method using an online form questionnaire„ 27 questions developed consist of 8 items related to individual data, 19 items related to perception and driving behavior. The respond measures using 5 scale option answers (i.e. strongly disagree, disagree, quite agree, agree, and strongly agree). Based on average respondents’ answers, can be concluded that the tendency of behavior somewhat supports to in line with eco-driving behavior. After Q15 and Q18 omitted based on Pearson-product moment correlation, further analysis results showed that most of respondents categorized into mild tendency behavior (109 respondents). However, a mild tendency among female respondents are higher than male, and the strong tendency of males is higher than female respondents. Based on gender, there are no significant tendency behavior differences between male and female (p-value = 0, 320), and also among age groups (30y, 31-40y, 41-50y, and >50y), even though age >50 have a lower tendency to the behavior compare to other groups.

Highlights: • Dynamical behaviors of a discrete time eco-epidemiological system are discussed. • Global asymptotical stability of this system is obtained by an iteration scheme which can be expended to general dimensional discrete system. • More complex dynamical behaviors are obtained by numerical simulations. - Abstract: In this study, the dynamical behaviors of a discrete time eco-epidemiological system are discussed. The local stability, bifurcation and chaos are obtained. Moreover, the global asymptotical stability of this system is explored by an iteration scheme. The numerical simulations illustrate the theoretical results and exhibit the complex dynamical behaviors such as flip bifurcation, Hopf bifurcation and chaotic dynamical behaviors. Our main results provide an efficient method to analyze the global asymptotical stability for general three dimensional discrete systems.

A critical review of frameworks used for evaluating reliability and relevance of (eco)toxicity data: Perspectives for an integrated eco-human decision-making framework.

Roth, N; Ciffroy, P

Considerable efforts have been invested so far to evaluate and rank the quality and relevance of (eco)toxicity data for their use in regulatory risk assessment to assess chemical hazards. Many frameworks have been developed to improve robustness and transparency in the evaluation of reliability and relevance of individual tests, but these frameworks typically focus on either environmental risk assessment (ERA) or human health risk assessment (HHRA), and there is little cross talk between them. There is a need to develop a common approach that would support a more consistent, transparent and robust evaluation and weighting of the evidence across ERA and HHRA. This paper explores the applicability of existing Data Quality Assessment (DQA) frameworks for integrating environmental toxicity hazard data into human health assessments and vice versa. We performed a comparative analysis of the strengths and weaknesses of eleven frameworks for evaluating reliability and/or relevance of toxicity and ecotoxicity hazard data. We found that a frequent shortcoming is the lack of a clear separation between reliability and relevance criteria. A further gaps and needs analysis revealed that none of the reviewed frameworks satisfy the needs of a common eco-human DQA system. Based on our analysis, some key characteristics, perspectives and recommendations are identified and discussed for building a common DQA system as part of a future integrated eco-human decision-making framework. This work lays the basis for developing a common DQA system to support the further development and promotion of Integrated Risk Assessment. Copyright © 2016 Elsevier Ltd. All rights reserved.

Constructing an Evaluation Framework for Eco-Museum Operations-Management Performance, Based on the Case of Jhushan, Taiwan

Directory of Open Access Journals (Sweden)

Kuo-Wei Hsu

2018-06-01

Full Text Available The bamboo-art industry in Taiwan’s Jhushan Township is inseparable from local life. In the face of local industrial-development difficulties in smaller towns, the Taiwan government aimed to achieve a range of (redevelopment goals using eco-museums as collaboration platforms and required such museums to combine their operations management with cultural preservation, local industrial development, and local residents’ goals. As such, the likely future performance of such operations management has emerged as a crucially important factor in decision-making about whether such museums should be constructed. This study, therefore, reviews the relevant literature on the operations-management performance of museums, with special attention to eco-museums, and proposes an operations-management performance measurement framework for eco-museums based on that review and a two-stage questionnaire administered to experts. The first stage utilized the Fuzzy Delphi Method, which focuses on impact factors, and the second, the Analytica Network Process Method, deals with performance factors. The results indicate that the key impacts on the performance of eco-museums and their operations management were, in order of importance, (1 community symbiosis, (2 cultural inheritance, and (3 regional revitalization. The preservation of cultural heritage, local identity, and community participation are the most important criteria in the operations management of eco-museums, and Jhushan Town can promote such museums through these guidelines.

Eco-efficient services as a route towards sustainable development : between the traditional and the radical

Energy Technology Data Exchange (ETDEWEB)

Anttonen, M.

2012-07-01

The dissertation addresses eco-efficient services as a potential solution to environmental problems such as the ever-increasing use of natural resources. In short, eco-efficient services refer to service solutions that are based on fulfilling customers' needs instead of product ownership. Customer, whether a company or private household obtains services that solve his/her needs. Eco-efficiency refers to the analysis of an economic value of a product or production activity in relation to its environmental impacts. The aim of eco-efficiency is to optimize this relation. The dissertation consists of four journal articles and an introduction that draws the articles together. It studies what kinds of services with a potential to enhance eco-efficiency have emerged, which issues influence the supply and demand of these services and what kind of business models pertain to such services. One of the articles studies services directed to households and three of them analyze material efficiency services in the business-to-business sector. The findings indicate that these services have a strong connection to customers' everyday life and business. At the household sector ecological sustainability as such is not sufficient; the service in question needs to increase the everyday wellbeing of the customer. Likewise, at the business-to-business sector, the ecoefficient service needs to solve both ecological and economic efficiency issues of operative, everyday business. The origins of business-to-business services are varied, such as new logistics and ICTservices in chemical management service industry. The business models of these services are contextual and depend, among other things, on the service provider's position in the supply chain. (orig.)

2016-08-01

Full Text Available The aim of the methodologies described here is to propose measures and procedures for developing concepts and technological solutions, which are adapted to the local conditions, to build sustainable communities in developing countries and emerging economies. These methodologies are linked to the EcoCity framework outlined by VTT Technical Research Centre of Finland Ltd. for sustainable community and neighbourhood regeneration and development. The framework is the result of a long experience in numerous EcoCity related projects, mainly Nordic and European in scope, which has been reformulated in recent years to respond to the local needs in the previously mentioned countries. There is also a particular emphasis on close collaboration with local partners and major stakeholders. In order to illustrate how these methodologies can support EcoCity concept development and implementation, results from a case study in Egypt will be discussed. The referred case study relates to the transformation of New Borg El Arab (NBC, near Alexandria, into an EcoCity. The viability of the idea was explored making use of different methodologies (Roadmap, Feasibility Study, and Residents Energy Survey and Building Consumption Assessment and considering the Residential, Commercial/Public Facilities, Industrial, Services/Utilities, and Transport sectors.

The leaf area of forest canopies is both main attribute of stands controlling water balance through transpiration and interception, and "engine" driving stand growth, stand dynamics, and forest succession. While transpiration and interception dynamics are classic themes in forest hydrology, we present results from our eco-hydrological research on boreal trees to highlight how more recent eco-physiological insights into species specific controls over water use and leaf area such as hydraulic architecture, cavitation, sapwood-leaf area relationships, and root system controls over water uptake are providing new insights into integrated atmospheric-autecological controls over these hydrologic processes. These results are discussed in the context of newer eco-hydrological frameworks which may serve to aid in exploring how forest disturbance and subsequent trajectories of hydrologic recovery are likely to affect both forest growth dynamics and hydrology of forested landscapes in response to forest management, severe forest pest epidemics such as the Mountain Pine Beetle epidemic in Western Canada, and climate change.

Facilitation Processes and Skills Supporting EcoCity Development

Directory of Open Access Journals (Sweden)

Carmen Antuña-Rozado

2018-03-01

Full Text Available Ecocities can provide solutions for the improvement of human settlements around the world and the living conditions therein, but in the authors’ experience, only as long as they are able to address the following questions correctly: How to formulate an ecocity concept that, considering issues of general concern, can be at the same time adapted to different local conditions? What are the instruments supporting the development and implementation of ecocity solutions? VTT’s EcoCity concept for sustainable community and neighbourhood regeneration and development has been designed in response to the first question. Likewise, specific methodologies and effective facilitation processes and skills have been developed in response to the second question. Since the methodologies have been discussed in a previous scientific article, the present one focuses on the facilitation processes and skills, and also on other related, fundamental aspects like participation, adaptation, capacity building, etc. Facilitation processes supporting EcoCity development require matching “hard” and “soft” skills in a fluid way. The main findings are discussed with the help of two case studies: one in Medellín (Colombia, and the other one in Zambia.

2017-09-01

Full Text Available The aim is to determine possibility of developing eco-agrotourism on the Korcula Island. Due to growing diversification within agriculture and tourism, the combination of organic agriculture and ecotourism gives a new product- eco-agrotourism, which is increasingly recognized in the world tourism. Eco-agrotourism at the highest level combines the sustainability of both activities. In addition to the mentioned it supports and protects the diversity of ecosystems, the preservation of natural landscapes; promotes biodiversity, preserves rural architecture and cultural content, encourages the promotion and sale of ecological products as well as the synergy of the economy with the environment and the growth and development of local tourism. Eco-agrotourism is an opportunity for employment of the domicile population especially young people. This is particularly pronounced in less favored areas, such as islands. The results showed that the agrotourism farm owners have the ecological awareness about the importance of nature, authenticity and origin of products through organic agriculture, which is connected with the tradition and culture of the islands, and creates a strong interaction unified in eco-agrotourism. Also, the island of Korcula has basic preconditions for the development of agrotourism, in particular eco-tourism, such as: favorable climatic and geographical conditions, attractive landscapes, specific flora and fauna, tradition of agricultural production, availability of healthier and quality food, but also wealth of cultural goods, way of life, various events, dialects, folklore and gastronomy.

Ecological forecasting is critical in various aspects of our coupled human-nature systems, such as disaster risk reduction, natural resource management and climate change mitigation. Novel advancements are in urgent need to deepen our understandings of ecosystem dynamics, boost the predictive capacity of ecology, and provide timely and effective information for decision-makers in a rapidly changing world. Our study presents a smart system - Ecological Platform for Assimilation of Data (EcoPAD) - which streamlines web request-response, data management, model execution, result storage and visualization. EcoPAD allows users to (i) estimate model parameters or state variables, (ii) quantify uncertainty of estimated parameters and projected states of ecosystems, (iii) evaluate model structures, (iv) assess sampling strategies, (v) conduct ecological forecasting, and (vi) detect ecosystem acclimation to climate change. One of the key innovations of the web-based EcoPAD is the automated near- or real-time forecasting of ecosystem dynamics with uncertainty fully quantified. The user friendly webpage enables non-modelers to explore their data for simulation and data assimilation. As a case study, we applied EcoPAD to the Spruce and Peatland Responses Under Climatic and Environmental Change Experiment (SPRUCE), a whole ecosystem warming and CO2 enrichment treatment project in the northern peatland, assimilated multiple data streams into a process based ecosystem model, enhanced timely feedback between modelers and experimenters, ultimately improved ecosystem forecasting and made better use of current knowledge. Built in a framework with flexible API, EcoPAD is easily portable and will benefit scientific communities, policy makers as well as the general public.

Dou, Qiang; Cai, Jun

2016-01-01

Polylactide (PLA)/poly(butylene adipate-co-terephthalate) (PBAT)/bark flour of plane tree (PF) eco-composites were prepared via melt blending. The morphologies, mechanical properties, crystal structures and melting and crystallization behaviors of the eco-composites were investigated by means of scanning electron microscopy (SEM), mechanical tests, polarized light microscopy (PLM), wide angle X-ray diffraction (WAXD) and differential scanning calorimetry (DSC), respectively. It is shown that the interfacial adhesion between PLA matrix and PF is weak and the mechanical properties of PLA/PF eco-composites are poor. The titanate treatment improves the adhesion between the matrix and the filler and enhances the stiffness of the eco-composites. The toughness is improved by PBAT and ductile fractured surfaces can be found. The spherulitic size of PLA is decreased by the addition of PF. The α crystalline form of PLA remains in the composites. Compared with PF, T-PF (PF treated by a titanate coupling agent) and PBAT have negative effects on the crystallization of PLA. PMID:28773515

High gamma power in ECoG reflects cortical electrical stimulation effects on unit activity in layers V/VI

Science.gov (United States)

Yazdan-Shahmorad, Azadeh; Kipke, Daryl R.; Lehmkuhle, Mark J.

2013-12-01

Objective. Cortical electrical stimulation (CES) has been used extensively in experimental neuroscience to modulate neuronal or behavioral activity, which has led this technique to be considered in neurorehabilitation. Because the cortex and the surrounding anatomy have irregular geometries as well as inhomogeneous and anisotropic electrical properties, the mechanism by which CES has therapeutic effects is poorly understood. Therapeutic effects of CES can be improved by optimizing the stimulation parameters based on the effects of various stimulation parameters on target brain regions. Approach. In this study we have compared the effects of CES pulse polarity, frequency, and amplitude on unit activity recorded from rat primary motor cortex with the effects on the corresponding local field potentials (LFP), and electrocorticograms (ECoG). CES was applied at the surface of the cortex and the unit activity and LFPs were recorded using a penetrating electrode array, which was implanted below the stimulation site. ECoGs were recorded from the vicinity of the stimulation site. Main results. Time-frequency analysis of LFPs following CES showed correlation of gamma frequencies with unit activity response in all layers. More importantly, high gamma power of ECoG signals only correlated with the unit activity in lower layers (V-VI) following CES. Time-frequency correlations, which were found between LFPs, ECoGs and unit activity, were frequency- and amplitude-dependent. Significance. The signature of the neural activity observed in LFP and ECoG signals provides a better understanding of the effects of stimulation on network activity, representative of large numbers of neurons responding to stimulation. These results demonstrate that the neurorehabilitation and neuroprosthetic applications of CES targeting layered cortex can be further improved by using field potential recordings as surrogates to unit activity aimed at optimizing stimulation efficacy. Likewise, the signatures

Eco-Evo-Devo: developmental symbiosis and developmental plasticity as evolutionary agents.

Science.gov (United States)

Gilbert, Scott F; Bosch, Thomas C G; Ledón-Rettig, Cristina

2015-10-01

The integration of research from developmental biology and ecology into evolutionary theory has given rise to a relatively new field, ecological evolutionary developmental biology (Eco-Evo-Devo). This field integrates and organizes concepts such as developmental symbiosis, developmental plasticity, genetic accommodation, extragenic inheritance and niche construction. This Review highlights the roles that developmental symbiosis and developmental plasticity have in evolution. Developmental symbiosis can generate particular organs, can produce selectable genetic variation for the entire animal, can provide mechanisms for reproductive isolation, and may have facilitated evolutionary transitions. Developmental plasticity is crucial for generating novel phenotypes, facilitating evolutionary transitions and altered ecosystem dynamics, and promoting adaptive variation through genetic accommodation and niche construction. In emphasizing such non-genomic mechanisms of selectable and heritable variation, Eco-Evo-Devo presents a new layer of evolutionary synthesis.

Human endocrine-cerebro-osteodysplasia (ECO) syndrome, caused by the loss-of-function mutation R272Q in the ICK (intestinal cell kinase) gene, is a neonatal-lethal developmental disorder. To elucidate the molecular basis of ECO syndrome, we constructed an Ick R272Q knock-in mouse model that recapitulates ECO pathological phenotypes. Newborns bearing Ick R272Q homozygous mutations die at birth due to respiratory distress. Ick mutant lungs exhibit not only impaired branching morphogenesis associated with reduced mesenchymal proliferation, but also significant airspace deficiency in primitive alveoli concomitant with abnormal interstitial mesenchymal differentiation. ICK dysfunction induces elongated primary cilia and perturbs ciliary Hedgehog signaling and autophagy during lung sacculation. Our study identifies an essential role for ICK in lung development and advances the mechanistic understanding of ECO syndrome. PMID:28380258

Absolute versus Relative Environmental Sustainability: What can the Cradle-to-Cradle and Eco-efficiency Concepts Learn from Each Other?

DEFF Research Database (Denmark)

Bjørn, Anders; Hauschild, Michael Zwicky

2013-01-01

The cradle-to-cradle (C2C) concept has emerged as an alternative to the more established eco-efficiency concept based on life cycle assessment (LCA). The two concepts differ fundamentally in that eco-efficiency aims to reduce the negative environmental footprint of human activities while C2C...... attempts to increase the positive footprint. This article discusses the strengths and weaknesses of each concept and suggests how they may learn from each other. The eco-efficiency concept involves no long-term vision or strategy, the links between resource consumption and waste emissions are not well...... related to the sustainability state, and increases in eco-efficiency may lead to increases in consumption levels and hence overall impact. The C2C concept's disregard for energy efficiency means that many current C2C products will likely not perform well in an LCA. Inherent drawbacks are restrictions...

Blind source separation (BSS) algorithms extract neural signals from electroencephalography (EEG) data. However, it is difficult to quantify source separation performance because there is no criterion to dissociate neural signals and noise in EEG signals. This study develops a method for evaluating BSS performance. The idea is neural signals in EEG can be estimated by comparison with simultaneously measured electrocorticography (ECoG). Because the ECoG electrodes cover the majority of the lateral cortical surface and should capture most of the original neural sources in the EEG signals. We measured real EEG and ECoG data and developed an algorithm for evaluating BSS performance. First, EEG signals are separated into EEG components using the BSS algorithm. Second, the EEG components are ranked using the correlation coefficients of the ECoG regression and the components are grouped into subsets based on their ranks. Third, canonical correlation analysis estimates how much information is shared between the subsets of the EEG components and the ECoG signals. We used our algorithm to compare the performance of BSS algorithms (PCA, AMUSE, SOBI, JADE, fastICA) via the EEG and ECoG data of anesthetized nonhuman primates. The results (Best case >JADE = fastICA >AMUSE = SOBI ≥ PCA >random separation) were common to the two subjects. To encourage the further development of better BSS algorithms, our EEG and ECoG data are available on our Web site (http://neurotycho.org/) as a common testing platform.

Considering the unique relevance of Brazilian biodiversity, this research aims to investigate the main barriers to biodiversity-based R&D and eco-design development in a leading national company which has been commended for its innovation and sustainability. The methodology for this research was based on on-location visits, in-depth interviews, and consensus building among R&D, sustainability, and quality managers. A multi-criteria decision-making (MCDM) approach was adopted through interpretive structural modelling (ISM), a method that assists decision makers to transform complex models with unclear data into structural models. Some of the most influential barriers to biodiversity-based eco-design initiatives are "lack of legal incentive", "not enough demand from the market", and "not enough available knowledge/scientific data." The most relevant barrier was "no legal incentive" from government. Consequently, managers should concentrate their efforts in tackling those barriers that may affect other barriers known as 'key barriers'. Government should work decisively toward promoting a framework of legal incentives for bio-based eco-design; otherwise, metaphorically, "there is not carnival without the samba singer who pushes the rhythm". The results given here reveal the barriers for bio-based eco-design in a Brazilian leading company, and this is the first work combining ISM to barriers to biodiversity R&D and eco-design.

Species packing in eco-evolutionary models of seasonally fluctuating environments.

Science.gov (United States)

Kremer, Colin T; Klausmeier, Christopher A

2017-09-01

As ecology and evolution become ever more entwined, many areas of ecological theory are being re-examined. Eco-evolutionary analyses of classic coexistence mechanisms are yielding new insights into the structure and stability of communities. We examine fluctuation-dependent coexistence models, identifying communities that are both ecologically and evolutionarily stable. Members of these communities possess distinct environmental preferences, revealing widespread patterns of limiting similarity. This regularity leads to consistent changes in the structure of communities across fluctuation regimes. However, at high amplitudes, subtle differences in the form of fluctuations dramatically affect the collapse of communities. We also show that identical fluctuations can support multiple evolutionarily stable communities - a novel example of alternative stable states within eco-evolutionary systems. Consequently, the configuration of communities will depend on historical contingencies, including details of the adaptive process. Integrating evolution into the study of coexistence offers new insights, while enriching our understanding of ecology. © 2017 John Wiley & Sons Ltd/CNRS.

Multitrophic microbial interactions for eco- and agro-biotechnological processes: theory and practice.

Science.gov (United States)

Saleem, Muhammad; Moe, Luke A

2014-10-01

Multitrophic level microbial loop interactions mediated by protist predators, bacteria, and viruses drive eco- and agro-biotechnological processes such as bioremediation, wastewater treatment, plant growth promotion, and ecosystem functioning. To what extent these microbial interactions are context-dependent in performing biotechnological and ecosystem processes remains largely unstudied. Theory-driven research may advance the understanding of eco-evolutionary processes underlying the patterns and functioning of microbial interactions for successful development of microbe-based biotechnologies for real world applications. This could also be a great avenue to test the validity or limitations of ecology theory for managing diverse microbial resources in an era of altering microbial niches, multitrophic interactions, and microbial diversity loss caused by climate and land use changes.

Exploring Eco-Costs and Externalities Absorption Policies and Procedures in the Context of Global Warming

Directory of Open Access Journals (Sweden)

Gina Raluca Guse

2011-06-01

Full Text Available A set of recent international studies reveal the scarcity of coherent entity-level estimation systems able to lead to an adequate identification and valuation of social and environmental performance, despite the large number of entities claiming their concern for the environmental impact of their business activities.The status quo is mainly caused by the lack of domain-specific accounting regulation, along with a general "information gap" in the field of the potential benefits eco-costs and externalities absorption may generate. Eco-costs and externalities absorption technologies for the costing model are still going through their experimental stages, aiming to reflect both the historicalpolitical context and the philosophical motivations of an organization's management and stakeholders. We held as appropriate (and the paper at hand will speak for the intent to promote this class of technologies for the Romanianbusiness environment, mainly by reviewing the relevant literature in the field and developing an eco-costing model able to provide cost levels consistent with the sustainable development goals.

Life cycle environmental evaluation of kettles: Recommendations for the development of eco-design regulations in the European Union.

Science.gov (United States)

Gallego-Schmid, Alejandro; Jeswani, Harish Kumar; Mendoza, Joan Manuel F; Azapagic, Adisa

2018-06-01

Between 117 and 200 million kettles are used in the European Union (EU) every year. However, the full environmental impacts of kettles remain largely unknown. This paper presents a comprehensive life cycle assessment of conventional plastic and metallic kettles in comparison with eco-kettles. The results show that the use stage contributes 80% to the impacts. For this reason, the eco-kettle has over 30% lower environmental impacts due to a greater water efficiency and related lower energy consumption. These results have been extrapolated to the EU level to consider the implications for proposed eco-design regulations. For these purposes, the effects on the impacts of durability of kettles and improvements in their energy and water efficiency have been assessed as they have been identified as two key parameters in the proposed regulations. The results suggest that increasing the current average durability from 4.4 to seven years would reduce the impacts by less than 5%. Thus, improving durability is not a key issue for improving the environmental performance of kettles and does not justify the need for an eco-design regulation based exclusively on it. However, improvements in water and energy efficiency through eco-design can bring relevant environmental savings. Boiling the exact amount of water needed would reduce the impacts by around a third and using water temperature control by further 2%-5%. The study has also considered the effects of reducing significantly the number of kettles in use after the UK (large user of kettles) leaves the EU and reducing the excess water typically boiled by the consumer. Even under these circumstances, the environmental savings justify the development of a specific EU eco-design regulation for kettles. However, consumer engagement will be key to the implementation and achievement of the expected environmental benefits. Copyright © 2017 Elsevier B.V. All rights reserved.

Enhanced CANDU6: Reactor and fuel cycle options - Natural uranium and beyond

International Nuclear Information System (INIS)

Ovanes, M.; Chan, P. S. W.; Mao, J.; Alderson, N.; Hopwood, J. M.

2012-01-01

The Enhanced CANDU 6 R (ECo R ) is the updated version of the well established CANDU 6 family of units incorporating improved safety characteristics designed to meet or exceed Generation III nuclear power plant expectations. The EC6 retains the excellent neutron economy and fuel cycle flexibility that are inherent in the CANDU reactor design. The reference design is based on natural uranium fuel, but the EC6 is also able to utilize additional fuel options, including the use of Recovered Uranium (RU) and Thorium based fuels, without requiring major hardware upgrades to the existing control and safety systems. This paper outlines the major changes in the EC6 core design from the existing C6 design that significantly enhance the safety characteristics and operating efficiency of the reactor. The use of RU fuel as a transparent replacement fuel for the standard 37-el NU fuel, and several RU based advanced fuel designs that give significant improvements in fuel burnup and inherent safety characteristics are also discussed in the paper. In addition, the suitability of the EC6 to use MOX and related Pu-based fuels will also be discussed. (authors)

Consumption of Eco-Innovative Food: How Values and Attitudes Drive Consumers’ Purchase of Organics?

Directory of Open Access Journals (Sweden)

Marcia Dutra de Barcellos

2015-04-01

Full Text Available Brazilian recent economic growth led to a rising demand for products that must satisfy desires that go beyond basic needs. Following this growth, social and environmental awareness upsurge, increasing demand for sustainable food, and subsequently, an opportunity for companies to add value through innovation in sustainable food products, e.g. to develop innovative ingredients and products (such as organics that provide healthiness for consumers and a sustainable offer for the market. Considering the importance of consumer evaluation for the adoption and success of an innovation, the aim of this paper is to investigate conscious consumption behaviour of organic food in Brazil. In specific, to verify the relationship between personal values, attitudes towards the environment and technology, and attitudes and consumer behaviour towards eco-innovative food. A survey with 401 consumers was held in organic street markets in Porto Alegre. Data was analysed through Structural Equation Modelling. Results indicate that consumers presented strong collectivistic values and very positive attitudes towards environment and nature. These attitudes positively influence the purchase of eco-innovative food. Attitudes towards technological progress negatively influence on its consumption. Theoretically, the hierarchical model is confirmed. This study addressed the consumption of eco-innovative food, in this case, organic food, trying to overtake the gap between attitudes and behaviour.  Public authorities and companies should work to increase consumer awareness and consumption of sustainable food, benefiting society and the natural environment, and must improve communication about the relevance of how technology can act to improve safety and increase the availability of eco-friendly food.

Assessing environmental performance in the European Union: Eco-innovation versus catching-up

International Nuclear Information System (INIS)

Beltrán-Esteve, Mercedes; Picazo-Tadeo, Andrés J.

2017-01-01

This paper assesses environmental performance in the European Union (EU) using Luenberger productivity indicators, directional distance functions and Data Envelopment Analysis techniques. It considers four indicators of the pressures exerted by economic activity on the environment: global warming, tropospheric ozone formation, acidification and particulate formation. The change in environmental performance from the early 2000s onwards is decomposed at the levels of country and environmental pressure, and as the result of eco-innovations and catching-up with the best available environmental technologies; furthermore, we distinguish between the periods of economic growth (2001–07) and severe crisis (2007–13). Our main finding is that environmental performance improved in both periods, mainly fuelled by advances in environmental technology. Accordingly, environmental policies aimed at boosting catching-up are highly recommended, particularly in the newer member states that joined the EU from 2004 onwards, which perform further away from their respective environmental technological frontiers. In addition, re-establishing the pre-crisis eco-innovation investment levels would also be highly advisable in order to return to the rates of environmental technical progress registered in the expansion period. - Highlights: • Environmental performance has noticeably improved in the EU since the 2000's. • Eco-innovations have bolstered progress in environmental performance. • Policies aimed at boosting catching-up are highly recommended in the EU.

Innovative eco-friendly bio- solvent for combating sea surface and sedimented oil pollution

Science.gov (United States)

Theodorou, Paraskevas

2017-04-01

The combating of oil spill at sea surface by chemical dispersants accelerates the evaporation and disperse the oil into the water column, where it is broken down by natural processes and/or is sedimented at the sea bottom, especially at near coastal shallow areas, ports and marinas. The usual methodology for cleaning the sedimented oil from the sea bottom is mainly carried out via excavation and dumping of the polluted sediment into deeper sea areas, where the contamination is transferred from one area to another. The eco-friendly bio-solvent MSL Aqua 250 is an innovative new solution based mainly on natural constituents. The action mechanism and the effectiveness of this eco-friendly solvent is based on the high surface tension process. Organic compounds, including hydrocarbons upon coming in contact with MSL Aqua 250 solvent generate a significant surface tension reaction, which is able to alter the organic compounds to liquid form and then to drastically evaporate it. The use of MSL Aqua 250 solvent, both at sea surface and at the bottom, has the following advantages compared to the dispersants: • Efficient solution without transferring the pollution from sea surface to the water column and to the bottom or disturbing the Aquatic Eco System. • Non-Toxic. • Environmentally friendly with a restoration of marine life in the Eco System. • Cost effective. The MSL Aqua 250 solvent has been tested in cooperation with the Cyprus Department of Fisheries and Marine Research and the Technological University of Cyprus and used during the years 2015 and 2016 in marinas and fishing shelters in Cyprus faced oil pollution, with high concentration in the sea water and at the sea bottom of chemical parameters (BOD5, COD, FOG, TKN, TP, TPH), with excellent results.

VanWey, Leah K.; Richards, Peter D.

2014-03-01

Garrett et al’s recent letter (2013 Environ. Res. Lett. 8 044055) shows the trade value of Brazil’s production of non-genetically modified (GM) crops, and argues that production for this niche market laid the foundation for the expansion of a variety of non-GM and eco-certification systems. We argue that the conditions underlying the development and perpetuation of the non-GM certification systems are transient. The expansion of soy production has dampened the conditions that promoted the dominance of non-GM soy in the region. The state at the heart of the production of conventional soy, Mato Grosso, already has transitioned to almost 90% GM soy in the most recent agricultural season. The continued viability of eco-certification systems depends on strengthening institutions on the demand side, and ensuring farm-level costs on the supply side match price premiums reaching the farm level.

Eco-labeling for energy efficiency and sustainability: a meta-evaluation of US programs

Energy Technology Data Exchange (ETDEWEB)

Banerjee, Abhijit; Solomon, Barry D

2003-01-01

Eco-labeling is a promising market-based approach for improving the environmental performance of products through consumer choice. While eco-labeling itself is not new, eco-labeling to promote energy efficiency or sustainability is a more recent phenomenon. Five such energy-labeling programs in the US are evaluated: Green Seal, Scientific Certification Systems, Energy Guide, Energy Star, and Green-e. Of these, the first four certify energy-efficient appliances while the last one certifies renewable electricity. While Energy Guide and Energy Star are government-run programs, the rest are privately administered. Two evaluation criteria were used--consumer response and manufacturer/marketer response. Very few studies have been done on the private programs making comparative analysis more difficult. It was found that government programs, in general, and Energy Star, in particular, were much more successful than the private programs. For appliance energy labeling, the private programs were found to have an almost insignificant effect on the market. Government support proved to be crucial in determining a program's credibility, financial stability, and long-term viability. Further, targeting of specific product categories, legislative mandates, incentives, and partnerships were found to be other important factors for program success. Simple seal-of-approval logos and labels have generally affected consumer behavior more than the complex information-disclosure labels.

Golden Gate cloning is a prominent DNA assembly tool in synthetic biology for the assembly of plasmid constructs often used in combinatorial pathway optimization, with a number of assembly kits developed specifically for yeast and plant-based expression. However, its use for synthetic biology in commonly used bacterial systems such as Escherichia coli has surprisingly been overlooked. Here, we introduce EcoFlex a simplified modular package of DNA parts for a variety of applications in E. coli, cell-free protein synthesis, protein purification and hierarchical assembly of transcription units based on the MoClo assembly standard. The kit features a library of constitutive promoters, T7 expression, RBS strength variants, synthetic terminators, protein purification tags and fluorescence proteins. We validate EcoFlex by assembling a 68-part containing (20 genes) plasmid (31 kb), characterize in vivo and in vitro library parts, and perform combinatorial pathway assembly, using pooled libraries of either fluorescent proteins or the biosynthetic genes for the antimicrobial pigment violacein as a proof-of-concept. To minimize pathway screening, we also introduce a secondary module design site to simplify MoClo pathway optimization. In summary, EcoFlex provides a standardized and multifunctional kit for a variety of applications in E. coli synthetic biology.

As the headstream of the Yellow River, the Yangtze River and the Lantsang River, located in the hinterland of Qinghai-Tibet Plateau, Qinghai province is hugely significant for ecosystem as well as for ecological security and sustainable development in China. With the accomplishment of the first national geographic condition census, the frequent monitoring has begun. The classification indicators of the census and monitoring data are highly correlated with Technical Criterion for Ecosystem Status Evaluation released by Ministry of Environmental Protection in 2015. Based on three years' geographic conditions data (2014-2016), Landsat-8 images and thematic data (water resource, pollution emissions, meteorological data, soil erosion, etc.), a multi-years and high-precision eco-environment status evaluation and spatiotemporal change analysis of Qinghai province has been researched on the basis of Technical Criterion for Ecosystem Status Evaluation in this paper. Unlike the evaluation implemented by environmental protection department, the evaluation unit in this paper is town rather than county. The evaluation result shows that the eco-environment status in Qinghai is generally in a fine condition, and has significant regional differences. The eco-environment status evaluation based on national geographic conditions census and monitoring data can improve both the time and space precision. The eco-environment status with high space precise and multi-indices is a key basis for environment protection decision-making.

Bing, Xiaoyun; de Keizer, Marlies; Bloemhof-Ruwaard, Jacqueline M; van der Vorst, Jack G A J

2014-04-01

Plastic waste is a special category of municipal solid waste. Plastic waste collection is featured with various alternatives of collection methods (curbside/drop-off) and separation methods (source-/post-separation). In the Netherlands, the collection routes of plastic waste are the same as those of other waste, although plastic is different than other waste in terms of volume to weight ratio. This paper aims for redesigning the collection routes and compares the collection options of plastic waste using eco-efficiency as performance indicator. Eco-efficiency concerns the trade-off between environmental impacts, social issues and costs. The collection problem is modeled as a vehicle routing problem. A tabu search heuristic is used to improve the routes. Collection alternatives are compared by a scenario study approach. Real distances between locations are calculated with MapPoint. The scenario study is conducted based on real case data of the Dutch municipality Wageningen. Scenarios are designed according to the collection alternatives with different assumptions in collection method, vehicle type, collection frequency and collection points, etc. Results show that the current collection routes can be improved in terms of eco-efficiency performance by using our method. The source-separation drop-off collection scenario has the best performance for plastic collection assuming householders take the waste to the drop-off points in a sustainable manner. The model also shows to be an efficient decision support tool to investigate the impacts of future changes such as alternative vehicle type and different response rates. Crown Copyright © 2014.

Böll, Albert; Gerber, Werner; Rickli, Christian; Graf, Frank

2010-05-01

Slopes affected by superficial sliding and subsequently re-stabilised with eco-engineering measures were investigated, particularly related to soil stability and plant diversity. The sites are situated in three different areas of beech-fir-spruce forest associations of the higher montane zone of Switzerland. Climatic and site characteristics, in paraticular soil properties after the sliding event, of the three investigation areas are very similar. However, the number of species (shrubs and trees) used for the initial planting as well as the year of application of the eco-engineering measures differ substantially. In the investigation area Dallenwil-Wirzweli the biological measures taken in 1981 were restricted to one tree species, namely White Alder (Alnus incana). In Klosters, where measures were taken in 1983 as well as in the Arieschbach valley, where eco-engineering was applied in 1998, the initial planting consisted of 15 species either. Investigations in 2005/2006 revealed neither obvious differences among the three areas nor distinct correlations related to the diversity of the initial planting on the on hand and the development of the vegetation cover and soil stability on the other hand. During the available time of development, the soil aggregate stability increased by 30 to 39%. Compared to the corresponding climax association, the relative values of soil aggregate stability varied between 90 and 120%. Concurrently, the dry unit weight decreased between 1.1 and 3.1 kN/m3. The cumulative vegetation cover varied from 110 to 150%. Due to processes of soil development a distinct shift in the grain size distribution was noticed, from a well sorted gravel with clay and sand (GW-GC) to a silty gravel with sand (GM) in Dallenwil-Wirzweli and a silty to clayey gravel with sand (GC-GM) in Klosters and the Arieschbach valley. Furthermore, in all three investigation areas succession processes were observed that are comparable to average rates of natural secondary

Pro-Cool is an EU-wide demonstration project which supports the development and market penetration of eco-efficient plug-in cold appliances for the commercial use. These products should be both highly energy efficient, free of HFC-containing refrigerants and -foaming agents and eco-efficient in a general sense. Thus the project corresponds with the EU Integrated Product Policy which aims at improving products by considering the ecological impact along the product life cycle. Besides ecological criteria, which are central for the project, other aspects relevant for purchasers like warranty and functionality are taken into account to guarantee the acceptance of the products by the demand side target groups. The so called 'voice of the customer' has been considered in the development of the criteria To achieve the necessary stimulation of the supply and demand side market a combined competition and procurement approach is developed addressing both manufacturers and buyers respectively users of the products. The central measure of the project is a European competition for suppliers what offers leading manufacturers of the market the opportunity to present themselves as innovative companies which provide eco-efficient equipment. Eight leading manufacturers which have a high market share in the selected product categories are taking part in the competition. Furthermore three large companies representing the demand side branches of super market chains and drinks industry already have signed a general agreement to support the project and to consider the products resulting from the competition in their procurement activities. Thus major supply and demand side target groups which are capable to support market transformation have joined the project. The competition terminates by December 2005 and the award of the winning products takes place in spring 2006 at an international fair or conference event. The paper presents the objectives and the concept of the project. Relevant

A systematical approach based on hierarchical eco-restoration system for the simultaneous removal of COD and dissolved nutrients was proposed and applied in a complex residential-cropland area in Kunming, China from August 2006 to August 2008, where the self-purifying capacity of the agricultural ecosystem had been lost. The system includes four main parts: (1) fertilizer management and agricultural structure optimization, (2) nutrients reuse, (3) wastewater treatment, and (4) catchment restoration. The results showed that the average removal efficiencies were 90% for COD, 93% for ammonia, 94% for nitrate and 71% for total dissolved phosphorus (TDP) when the hierarchical eco-restoration agricultural system was in a relatively steady-state condition. The emergence of 14 species of macrophytes and 4 species of zoobenthos indicated that the growth conditions for the plankton were improved. The results demonstrated that this promising and environmentally benign hierarchical eco-restoration system could decrease the output of nutrients and reduce downstream eutrophication risk. - A systematical approach based on hierarchical eco-restoration system has proven highly effective for simultaneously removing COD and dissolved nutrients, decreasing the output of nutrients, and reducing the eutrophic risk of downstream surface waters.

Dong, Xin; Zhang, Xinyi; Zeng, Siyu

2017-04-01

In the context of sustainable development, there has been an increasing requirement for an eco-efficiency assessment of wastewater treatment plants (WWTPs). Data envelopment analysis (DEA), a technique that is widely applied for relative efficiency assessment, is used in combination with the tolerances approach to handle WWTPs' multiple inputs and outputs as well as their uncertainty. The economic cost, energy consumption, contaminant removal, and global warming effect during the treatment processes are integrated to interpret the eco-efficiency of WWTPs. A total of 736 sample plants from across China are assessed, and large sensitivities to variations in inputs and outputs are observed for most samples, with only three WWTPs identified as being stably efficient. Size of plant, overcapacity, climate type, and influent characteristics are proven to have a significant influence on both the mean efficiency and performance sensitivity of WWTPs, while no clear relationships were found between eco-efficiency and technology under the framework of uncertainty analysis. The incorporation of uncertainty quantification and environmental impact consideration has improved the liability and applicability of the assessment. Copyright © 2017 Elsevier Ltd.

A new trend in the world is the clothing production using the new types of ecological raw materials application - milk, pineapple, coconut, hemp, banana, eucalyptus, clams, corn, bamboo, soya, nettle yarn. This makes it possible to create textile materials of new generation with unique antibacterial and antiseptic properties. Such materials have a positive preventive and sometimes therapeutic effect on people, and their health. Eco-raw materials clothing is able to protect the human body from the environment harmful effects: cold, heat, rain, dust, opportunely remove from underclothing layer the steam and gases, sweat; maintain in underclothing layer the necessary microclimate for normal organism functioning. Study of knitwear consumer properties, produced with eco-materials, is an urgent task of the world vector, directed on ecological environmental protection. This paper presents the research results of hygroscopicity and capillarity weft knitted fabrics, what knitted from different types of eco-raw materials: bamboo yarn, yarn containing soybean and nettle yarn. Character of influence of the liquid raising level changes depending on the experiment time and the knitting structure is revealed.

Ecological risks of heavy metals in urban soils were evaluated using Beijing, China as an example. Cadmium, Cu, Zn, Pb, Cr and Ni contents of 233 surface soils sampled by 1 min latitude × 1 min longitude grid were used to identify their spatial distribution patterns and potential emission sources. Throughout the city, longer the duration of urbanization greater was the accumulations of heavy metals especially, Cd, Cu, Pb, and Zn. The soil Zn mainly came from the wears of vehicular tires. Point source emissions of heavy metals were few and far in the downwind south-east quadrant of Beijing. The calculated risk indices showed potential median eco-risks in the ancient central city. No potential high eco-risk due to soil-borne heavy metals was found. The potential medium eco-risk areas in Beijing would expand from the initial 24 to 110 km(2) if soil pH were to reduce by 0.5 units in anticipation. Copyright © 2011 Elsevier Ltd.

Fly ash (FA) and Alccofine are the eco-friendly materials that can be used in the production of concrete composites. Initially, concrete mixes of M30 grade with replacement of cement by 0%, 5%, 10%, 15%, 20% and 25% by weight of Fly ash were prepared. They were subjected to compression test so as to select the optimum replacement percentage of FA. Keeping this optimum percentage of FA as constant, additional replacement of cement with Alccofine was done varying its replacement in the range of 8%, 10%, 12% and 14%. The mechanical properties such as compressive, split tensile and flexural strengths of these mixes were computed for 7, 14 and 28 days. The results of Eco-Friendly Concrete (EFC) are compared with those of control concrete. It was observed that EFC mixes exhibited superior qualities like quick setting and enhanced workability, their mechanical properties were found to be higher than that of the conventional concrete. This goes to prove that the combination of FA and Alccofine together as replacement for cement would enhance the properties of EFC.

The conflict among water drainage,water supply and eco-environment protection is getting more and more serious due to the irrational drainage and exploitation of ground water resources in coal-accumulated basins of North China.Efficient solutions to the conflict are to maintain long-term dynamic balance between input and output of the ground water basins,and to try to improve resourcification of the mine water.All solutions must guarantee the eco-environment quality.This paper presents a new idea of optimum combination of water drainage,water supply and eco-environment protection so as to solve the problem of unstable mine water supply,which is caused by the changeable water drainage for the whole combination system.Both the management of hydraulic techniques and constraints in economy,society,ecology,environment,industrial structural adjustments and sustainable developments have been taken into account.Since the traditional and separate management of different departments of water drainage,water supply and eco-environment protection is broken up,these departments work together to avoid repeated geological survey and specific evaluation calculations so that large amount of national investment can be saved and precise calculation for the whole system can be obtained.In the light of the conflict of water drainage,water supply and eco-environment protection in a typical sector in Jiaozuo coal mine,a case study puts forward an optimum combination scheme,in which a maximum economic benefit objective is constrained by multiple factors.The scheme provides a very important scientific base for finding a sustainable development strategy.

Microstructure of the eco-material combining vegetation recovery with slope protection is important for determining plant-growing properties.Several techniques for analyzing the eco-material microstructure are presented,including the freeze-cut-drying method of preparing samples for scanning electronic microscopy (SEM),the SEM image processing technique and quantifying analysis method of the SEM images,and etc.The aggregates and pores in SEM images are identified using the different mathematics operators,and their effects are compared.The areas of aggregates and pores are obtained using the operator of morphology,and the influences of different thresholds in image segmentation are also discussed.The results show that the method,in which the variation of non-maximum grey-level gradient is limited,improves the effect of edge detections due to a weak distinction existing at the edge between the aggregates and pores in image.The determination of the threshold should combine the image characteristic with filling operation,so as to assure the precision of the image analysis,in which the contact-segmentation is the simplest and most effective method.The results also show that the pore areas in eco-materials are generally larger than those in the correlative soils,and their increment is large as soil fabric being fine.These differences are related to admixture of expansive perliticThe operator of morphology provides a new method for the image analysis of other porous material microstructure such as soils and concretes.

Mangrove forests in North Sumatera, Indonesia existed in the east coast of Sumatera Island and commonly thrived in Langkat, Deli Serdang, Batubara, Tanjung Balai, Asahan, Labuhanbatu until Serdang Bedagai. The present study describes the developing community-based mangrove management (CBMM) through eco-tourism in two locations, Lubuk Kertang (LK) of Langkat and Sei Nagalawan (SN) of Serdang Bedagai, North Sumatra, Indonesia. Mangrove ecosystem, coastal villagers and visitors, and related stakeholder were analyzed to present the potential of mangrove ecosystem, the ecological suitability, and the carrying capacity then continued with SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis. Results showed that mangrove diversity in LK consist of fifteen species which Rhizophora apiculata and Avicennia lanata dominated the area, where mangroves in SN found seven species dominated by R. apiculata and A. officinalis. Based on the suitability level of mangrove ecosystem for ecotourism development, LK and SN were categorized as suitable and conditionally suitable, respectively. The carrying capacity of mangrove ecotourism for LK and SN were 36 and 36 people/day respectively. SWOT analysis revealed that both locations of eco-tourism have a potential eco-tourism attraction, high mangrove biodiversity, possible human resources, and real people’s perception on the importance of mangrove conservation, and relatively easy access. The study present suggested that mangrove ecotourism is a sustainable form of land use, to contributing the environmental protection and providing socio-economic benefits to the local people through indirect values of the natural resources.

Ecology: Its relative importance and absolute irrelevance for a Christian: A Kierkegaardian transversal space for the controversy on eco-theology

Full Text Available The controversy about the importance of eco-theology or creation spirituality seems to be in a deadlock. Those who support it and those who oppose it do not even seem to be able to communicate with one another. On the one hand, Celia Deane-Drummond, for example, writes in her Eco-theology (2008:x: ‘I find it astonishing that courses on eco-theology do not exist in many university departments of theology and religious studies.’ Matthew Fox desperately asks in his Creation spirituality (1991:xii: ‘Need I list the [environmental] issues of our day that go virtually unattended to in our culture?’ On the other hand, evangelical Christians are known for their ecological ‘blind spot’ (Davis 2000, until recently at least. Pentecostal proponents of the prosperity gospel preach a consumer-lifestyle for all Christians, which is not very eco-friendly (cf. Kroesbergen 2013. Even in more mainline Christianity we find, for example, the well-known theologian Robert Jenson who writes in his Systematic theology: Volume 2 (1999:113, n. 2: ‘Recent waves of “creation spirituality” are simply apostasy to paganism. And it is such unguarded, even unargued judgement that is required of the church.’ We find eco-theologians, who do not understand that not everyone agrees with them on the one hand, and opposing theologians, who do not even feel the need to argue against them on the other hand. What would be needed to re-open communication between those in favour of eco-theology or creation spirituality, and those opposed to it?

Full Text Available Le reti d’impresa che operano nel campo dell’efficienza energetica e dell’eco-sostenibilità del territorio possono innescare uno sviluppo sostenibile, innovativo e inclusivo e, per questa via, lo sviluppo locale. È questa l’ipotesi che ci si propone di verificare sulla base dei risultati di un’analisi econometrica che mostra i benefici della presenza di reti tra imprese in termini di riduzione dell’intensità energetica, di potenziamento della capacità innovativa e di impatto occupazionale, sempre a livello regionale. The inter-firm networks that operate in the field of energy efficiency and eco-sustainability of local territories can trigger sustainable, innovative and inclusive development. We aim to check this hypothesis through an econometric analysis for Italy at the regional level. Empirical results show a positive impact of green inter-firm networks in terms of reduction of energy intensity, enhancement of innovative capacity, and increase in the employment rates.
