  1. Is the Green Revolution Vanishing? Empirical Evidence from TFP Analysis for Rice

    OpenAIRE

    Adlas, J.; Achoth, Lalith

    2006-01-01

    A serious concern has been raised recently on the long run sustainability of the productivity effects of Green Revolution technologies in the light of decelerating trend in the yield growth of rice since the mid 1980s under irrigated ecosystem. However, the changes in physical yield are not true measures of productivity from efficiency perspective. Total factor productivity (TFP) is a true measure of economic efficiency of any technology impact. The paper addresses the crucial issue of "is gr...

  2. Productivity of Nations: A Stochastic Frontier Approach to TFP Decomposition

    2012-01-01

    Full Text Available This paper tackles the problem of aggregate TFP measurement using stochastic frontier analysis. We estimate a world production frontier for a sample of 75 countries over a long period. The “Bauer-Kumbhakar” decomposition of TFP is applied to a smaller sample in order to evaluate the effects of changes in efficiency (technical and allocative, scale effects, and technical change. Estimated technical efficiency scores are compared to productivity indexes offered by nonfrontier studies. We conclude that differences in productivity are responsible for virtually all the differences of growth performance between developed and developing nations and that a large part of this is due to allocative efficiency.

    The Dutch Sustainable Growth Coalition (DSGC) has the following objectives: The DSGC aims to pro-actively drive sustainable growth business models along three lines: (1) Shape. DSGC member companies aim to connect economic profitability with environmental and social progress on the basis of integrated sustainable growth business models; (2) Share. DSGC member companies aim for joint advocacy of sustainable growth business models both internationally and nationally; and (3) Stimulate. DSGC member companies aim to stimulate and influence the policy debate on enabling sustainable growth - with a view to finding solutions to the environmental and social challenges we are facing. This is their first report. The vision, actions and mission of DSGC are documented in the Manifesto in Chapter 2 of this publication. Chapter 3 contains an overview of key features of an integrated sustainable growth business model and the roadmap towards such a model. In Chapter 4, project examples of DSGC members are presented, providing insight into the hands-on reality of implementing the good practices. Chapter 5 offers an overview of how the Netherlands provides an enabling environment for sustainable growth business models. Chapter 6 offers the key conclusions.

    One of the large problems of lidar in practical use is that the price and the weight of a laser and a receiving telescope is too high. To solve this problem, many trials have been made. The system with the TFP (thin film paraboloid) for a receiving telescope and a pulsed LD (laser diode) for a laser source is proposed. It is hoped that as a consequece the lidar system will become very lightweigth and inexpensive.

    In transitional stage saving rate play an important role in output growth rate as proposed by Krugman. Accumulationists are also right as claiming that learning-by-doing play an important role in TFP growth in NIEs. However, using a CES production technology we can show that the growth model based purely on learning-by-doing is constrained by labor growth rate. If the latter is constant in the long-run, then the growth can not be sustained.

  15. 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.

    Full Text Available Macro-level manmade problems can often be best solved by understanding and manipulating the economics behind it. The world today is facing genuine problems of scarcity of resources and environmental amp ecological issues in view of intergenerational equity. The paper proposes a new approach of identification and classification of i Resources and ii Goods and services in the context of sustainable development. Every economy has ambitious economic growth aspirations which are often found conflicting with the commitments on natural resource conservation and climate change obligations. The proposed methodology is a reconciliation of the aspired economic growth of a region and the conservation of the resources and nature. The paper employs contribution of different types of goods and services in the gross domestic product GDP of a region to analyze sustainability of development. The important parameters that the paper establishes are Sustainability Ratio R Sustainable Growth Rate SG and the Sustainable Development Index SI. These parameters can be used to compare the sustainable development level of different regions. Ensuring natural resource and environmental sustainability will eventually ensure economic sustainability. The paper considers resource depletion concerns as well as the environmental pollutants biological risks carbon footprint warhead proliferation et cetera thereby ensuring all round sustainability from survival to economic end. The sustainability analysis is done for long periods such as 50 years 100 years et cetera. The index shows how sustainable the development of an economy is and how sustainability it is growing. The presently much revered GDP growth numbers are directionless it does not tell the type of growth an economy essentially has. The direction should be sustainability which the paper stresses upon. An illustration of sustainability analysis of India is also done. Such indices can help identifying sustainably developing

    Korea has become one of the leading countries in nanotechnology along with the U.S., Japan, and Germany. Since 2001, the Korean Government established the "Nanotechnology Development Plan." Since then, the trend in nanotechnology is steadily changing from fundamental research to application-driven technologies. In this paper, we examine the nanotechnology development and policy during the past decade, which includes the investments in R&D, infrastructure, and education. The Third Phase (2011-2020) on clean nanotechnology convergence and integration in information, energy, and the environmental sector is also given. Furthermore, the program on long-term strategy dealing with sustainability in resolving future societal demand and plans for sustainable energy and environmental activities will be discussed in depth. The outcomes and national evaluations of research and education are also given.

    Full Text Available There are many studies that look into the relationship between public debt and economic growth. It is hard to find, however, research addressing the role of corruption between these two variables. Noticing this vacancy in current literature, we strive to investigate the effect of corruption on the relationship between public debt and economic growth. For this purpose, the pooled ordinary least squares (OLS, fixed effects models and the dynamic panel generalized method of moments (GMM models (Arellano-Bond, 1991 are estimated with data of 77 countries from 1990 to 2014. The empirical results show that the interaction term between public debt and corruption is statistically significant. This confirms the hypothesis that the effect of public debt on economic growth is a function of corruption. The sign of the marginal effect is negative in corrupt countries, but public debt enhances economic growth within countries that are not corrupt, i.e., highly transparent.

  6. Financial Markets and the Challenges of Sustainable Growth

    Directory of Open Access Journals (Sweden)

    Janicka Małgorzata

    2016-06-01

    Full Text Available Sustainable growth and responsibility for the economy and the environment are postulates rarely associated with the term “financial market”. Financial markets are identified with the ruthless maximisation of profit at acceptable risk, rather than with socially responsible conduct. However, in the global economy businesses modify their priorities and become aware of not just the need to grow in financial terms but also to improve their quality performance. International financial markets have become part of this trend and are increasingly often adopting environmentally friendly attitudes and embracing the challenges posed by the concept of sustainable growth. Ideas such as CSR – Corporate Social Responsibility – and SRI – Socially Responsible Investment are gaining in importance. While sustainable growth of the economy as perceived from the point of view of the manufacturing or service sectors is widely discussed, the sustainable growth of financial markets is a relatively new concept and the available literature on “green” financial markets is quite scarce. This paper is intended to fill in this gap and examine the changes that have taken place on financial markets in the context of the idea of sustainable growth, with particular attention paid to the European Union markets.

    This study examined the long-run and causal relationships between international tourism, biodiversity loss, environmental sustainability, and specific growth factors under the premises of sustainable tourism in Austria, by using a consistent time series data from 1975 to 2015. The results reveal that inbound tourism, per capita income, and population density affected the potential habitat area while population density largely affected the food production in a country. Inbound tourism and population density both deteriorate the environmental quality in a form of increasing carbon dioxide (CO2) emissions and fossil fuel energy consumption while per capita income reduces the fossil fuel energy consumption. Food exports increase per capita income, while food imports and population density both decrease economic growth. Inbound tourism and economic growth advance population density while forest area and food exports decrease the population density. The study supports growth-led tourism and growth-led food production in a country.

The focus of the study is on subsidies for co-financing purchases of new technological equipment aimed at promoting innovation and production of new products. Subsidies are distributed based on the prepared European Union (EU and national programs for the purposes of faster economic growth in accordance with the policies and guidelines of the EU. The paper employs a combination of enterprises’ accounting data, data on subsidies and unique in-depth data obtained through a survey at the enterprise level. The results revealed a positive impact of subsidies on financial indicators, and only limited effect on innovation. While analyzing sustainable growth, we have established that the enterprises that received subsidies had a higher growth of financial indicators.

    Full Text Available The emergence of the Internet as a measureable manifestation of our social and economic relationships changed the domination of networks in our lives. From about 2000, the internet has allowed us to study and understand the type of networks in which we live, and to model their behaviour. The Internet has fundamentally changed the distribution of wealth. The rich became richer simply because of the larger scale of the trading network and stretched national wealth distributions. Network effects are therefore likely to be responsible for much of the perceived increases in inequalities in the last 20-30 years, and policies to tackle poverty must therefore address the extent to which the poor can engage with society's networks of wealth creation. The greatest challenge to continued growth and prosperity, and therefore to peace and justice, is climate change. The potential cost of inaction on climate change could be as high. Our self-organising social networks have structured our societies and economies, and are now reflected in our technology networks. We can now replicate their evolution in computer simulations and can therefore better assess how to deal with the greatest challenges facing us in the next few decades.

    Full Text Available The subject “economic growth and sustainability” refers to the relationship between economicgrowth and its positive impact on the wellbeing of the population and on the environment. It is,therefore, about economic, as well as social and environmental, sustainability, i.e. the root ofthe sustainable development paradigm.

    Full Text Available The demographic dynamics analysed in the context of the relationship between economic development and social inclusion presents an image of the sustainable development of a community as well as the manner how the financial resources have been used. With an allocation of 74.3 million euro in the programming period 2007-2013, the Brasov Growth Pole has pursued the contribution to the achievement of sustainable development since 2005 by the participation in the Agenda 21. The implementation of projects with European financing in areas such as transport, social and educational infrastructure or tourism have generated changes/demographic movements, which this paper proposes to present. The evolution of the stable population, its dynamics at the level of each locality that is part of the Brasov growth pole as well as the dynamics of the number of employees or the development of the unemployment rate are presented by the cluster analysis. The effects of the European financing obtained from Regional Operational Programme 2007-2013 are thus reflected in the sustainable development of the Brasov growth pole from the point of view of the dynamics of the population

    Michaelides, Panayotis; Theologou, Kostas; Vouldis, Angelos

    The purpose of this paper is to analyze in terms of security the complexity of European Air Transport after the 2001 terrorist attack, taking into account Total Factor Productivity (T.F.P.) change. Our approach regards European Air Transport as a complex system of airplanes, airports and control. The investigation is based on recent data from the Amadeus database for the largest European (EU-27) air transportation companies (1997-2005). The paper employs the Cobb-Douglas specification of the production function and, in this context, tests the hypothesis that the 2001 terrorist attack had a significant influence on the performance of the EU-27 air transportation companies. An interesting finding is that except for some companies that were negatively influenced, several others were positively influenced by the 2001 terrorist attack. The technological level of the companies included in our dataset remained almost unchanged. The empirical findings are discussed and some suggestions are made regarding policy issues.

  17. Cell longevity and sustained primary growth in palm stems.

    Science.gov (United States)

    Tomlinson, P Barry; Huggett, Brett A

    2012-12-01

    Longevity, or organismal life span, is determined largely by the period over which constituent cells can function metabolically. Plants, with modular organization (the ability continually to develop new organs and tissues) differ from animals, with unitary organization (a fixed body plan), and this difference is reflected in their respective life spans, potentially much longer in plants than animals. We draw attention to the observation that palm trees, as a group of monocotyledons without secondary growth comparable to that of lignophytes (plants with secondary growth from a bifacial cambium), retain by means of sustained primary growth living cells in their trunks throughout their organismal life span. Does this make palms the longest-lived trees because they can grow as individuals for several centuries? No conventional lignophyte retains living metabolically active differentiated cell types in its trunk for this length of time, even though the tree as a whole can exist for millennia. Does this contrast also imply that the long-lived cells in a palm trunk have exceptional properties, which allows this seeming immortality? We document the long-life of many tall palm species and their inherent long-lived stem cell properties, comparing such plants to conventional trees. We provide a summary of aspects of cell age and life span in animals and plants. Cell replacement is a feature of animal function, whereas conventional trees rely on active growth centers (meristems) to sustain organismal development. However, the long persistence of living cells in palm trunks is seen not as evidence for unique metabolic processes that sustain longevity, but is a consequence of unique constructional features. This conclusion suggests that the life span of plant cells is not necessarily genetically determined.

  18. Resource Demand Growth and Sustainability Due to Increased World Consumption

    Directory of Open Access Journals (Sweden)

    Alexander V. Balatsky

    2015-03-01

    Full Text Available The paper aims at continuing the discussion on sustainability and attempts to forecast the impossibility of the expanding consumption worldwide due to the planet’s limited resources. As the population of China, India and other developing countries continue to increase, they would also require more natural and financial resources to sustain their growth. We coarsely estimate the volumes of these resources (energy, food, freshwater and the gross domestic product (GDP that would need to be achieved to bring the population of India and China to the current levels of consumption in the United States. We also provide estimations for potentially needed immediate growth of the world resource consumption to meet this equality requirement. Given the tight historical correlation between GDP and energy consumption, the needed increase of GDP per capita in the developing world to the levels of the U.S. would deplete explored fossil fuel reserves in less than two decades. These estimates predict that the world economy would need to find a development model where growth would be achieved without heavy dependence on fossil fuels.

    Alterations in genes that regulate brain size may contribute to both microcephaly and brain tumor formation. Here, we report that Aspm, a gene that is mutated in familial microcephaly, regulates postnatal neurogenesis in the cerebellum and supports the growth of medulloblastoma, the most common malignant pediatric brain tumor. Cerebellar granule neuron progenitors (CGNPs) express Aspm when maintained in a proliferative state by sonic hedgehog (Shh) signaling, and Aspm is expressed in Shh-driven medulloblastoma in mice. Genetic deletion of Aspm reduces cerebellar growth, while paradoxically increasing the mitotic rate of CGNPs. Aspm-deficient CGNPs show impaired mitotic progression, altered patterns of division orientation and differentiation, and increased DNA damage, which causes progenitor attrition through apoptosis. Deletion of Aspm in mice with Smo-induced medulloblastoma reduces tumor growth and increases DNA damage. Co-deletion of Aspm and either of the apoptosis regulators Bax or Trp53 (also known as p53) rescues the survival of neural progenitors and reduces the growth restriction imposed by Aspm deletion. Our data show that Aspm functions to regulate mitosis and to mitigate DNA damage during CGNP cell division, causes microcephaly through progenitor apoptosis when mutated, and sustains tumor growth in medulloblastoma. © 2015.

    The biofuel industry is divided into four categories comprising of feedstocks used in 1st and 2nd generation bioethanol and biodiesel. In order to identify and quantify each biofuel feedstock's potential for sustainable growth, each were evaluated according to self-developed social, financial, and environmental criteria. From the investigation and analysis carried out, 1st generation biodiesel and bioethanol were determined to be feedstocks not capable of facilitating sustainable growth. Results showed low earnings before interest, taxes, depreciation and amortization (EBITDA) of -0.5 to 1 USD per gallon for biodiesel and 0.25 to 0.5 USD per gallon for bioethanol. Results also showed a poor return on asset (ROA). The energy required to produce one MJ of 1st generation biofuel fuel was at least 0.4 MJ, showing poor energy balance. Furthermore, high land, water, pesticide, and fertilizer requirements strained surrounding ecosystems by affecting the food web, thus reducing biodiversity. Over 55% of land used by the biodiesel industry in Indonesia and Malaysia involved the deforestation of local rainforests. This not only displaced indigenous organisms from their habitat and decreased their scope of nutrition, but also contributed to soil erosion and increased the probability of flooding. If left unregulated, imbalances in the ecosystem due to unsustainable growth will result in a permanent reshaping of tropical rainforest ecosystems in Southeast Asia. Algae, an example of 2nd generation biodiesel feedstock, was concluded to be the biofuel feedstock most capable of supporting sustainable growth. This is due to its low production costs of $1-1.5/gal, high biological productivity of 5000 gallons of biodiesel per acre per year, and high ROA of 25-35%. Additionally, algae's adaptability to varying environmental conditions also makes it an appealing candidate for businesses in developing countries, where access to resource supplies is unstable. Additionally, its reduced net

  3. Examining the contradiction in 'sustainable urban growth': an example of groundwater sustainability

    Science.gov (United States)

    Zellner, Moira L.; Reeves, Howard W.

    2012-01-01

    The environmental planning literature proposes a set of 'best management practices' for urban development that assumes improvement in environmental quality as a result of specific urban patterns. These best management practices, however, often do not recognise finite biophysical limits and social impacts that urban patterns alone cannot overcome. To shed light on this debate, we explore the effects of different degrees of urban clustering on groundwater levels using a coupled land-use change and groundwater-flow model. Our simulations show that specific urban forms only slow down the impact on groundwater. As population increases, the pattern in which it is accommodated ceases to matter, and widespread depletion ensues. These results are predictable, yet current planning practice tends to take growth for granted and is reluctant to envision either no-growth scenarios or the prospect of depletion. We propose to use simulations such as those presented here to aid in policy discussions that allow decision makers to question the assumption of sustainable growth and suggest alternative forms of development.

    The focus of the work is to highlight the present environmental and social impacts of extensive mining on the health of the common people of Odisha. The mining activities have created havoc impact to the environment and social life of the state. Odisha has huge deposits of ores and minerals of chromite, nickel, bauxite, iron, coal, copper, manganese, graphite, vanadium etc. The mining activities have encouraged rapid urbanization and at the same time have altered the topography of these areas and extensively degraded the forest land. For long term sustainable development of the society, it is necessary to take a balanced and integrated approach towards environmental protection and economic advancement. Industries should aim at achieving their goals, through a system of permits based on best available techniques, which gives emphasis on integrated prevention and control of consumption of energy and water as well as pollution of water, air and soil. The rapid industrial growth has brought promising opportunities for economic development and poverty reduction in Odisha but at the same time has caused extensive environmental degradation. The best management practices to deal with environmental and social impacts on mineral-intensive growth are suggested in this work. In addition to lean technology, economic implications of the introduction of environmental technologies for mining activities are also discussed.

    'Sustainable de-growth' is both a concept and a social-grassroots (Northern) movement with its origins in the fields of ecological economics, social ecology, economic anthropology and environmental and social activist groups. This paper introduces the concept of sustainable de-growth by mapping some of the main intellectual influences from these fields, with special focus on the Francophone and Anglophone thinking about this emergent notion. We propose hypotheses pertaining to the appeal of sustainable de-growth, and compare it to the messages enclosed within the dominant sustainable development idea. We scrutinize the theses, contradictions, and consequences of sustainable de-growth thinking as it is currently being shaped by a heterogeneous body of literature and as it interacts with an ample and growing corpus of social movements. We also discuss possible future paths for the de-growth movement compared to the apparent weakening of the sustainable development paradigm. (author)

    2017-10-01

    Full Text Available The persistent increase of government debt in Malaysia in the recent years has raised con-cerns as to whether the borrowings have spurred the economy or became a drag on econom-ic growth. The present paper investigates the real effect of government debt on sustainable economic growth in Malaysia using the Autoregressive Distributed Lag approach for the period of 1970-2015. The results show there are positive significant long- and short-run relationships between government debt and sustainable economic growth. There is also a unidirectional causality running from government debt to sustainable economic growth. The findings indicate that Malaysia’s government debt is an important macroeconomic element for sustainability of economic growth in Malaysia. There is no evidence, however, to con-clude that the level of government debt had any adverse impacts on sustainable economic growth.

    Full Text Available This paper intends to analyse the correlation between the level of economic growth of a country and its rural development. The phrase sustainable development combines the economic growth and the preservation and improvement of environmental and human health, preservation of social justice and assurance of democratic environment in social life. Therefore, the sustainable economic growth provides for the meeting of current consumption requirements without compromising or prejudicing those of the future generations. By adding the requirements regarding environmental protection and preservation of natural resources to economic growth we may speak of a proper sustainable development.

    Currently, traditional development issues such as economic stagnation, poverty, hunger, and illness as well as newer challenges like environmental degradation and globalisation demand attention. Sustainable development, including its economic, environmental and social elements, is a key goal of decisionmakers. Optimal economic growth has also been a crucial goal of both development theorists and practitioners. This paper examines the conditions under which optimal growth might be sustainable, by assessing the costs and benefits of growth. Key environmental and social aspects are considered. The Ecol-Opt-Growth-1 model analyses economic-ecological interactions, including resource depletion, pollution, irreversibility, other environmental effects, and uncertainty. It addresses some important issues, including savings, investment, technical progress, substitutability of productive factors, intergenerational efficiency, equity, and policies to make economic growth more sustainable-a basic element of the sustainomics framework. The empirical results support growing concerns that costs of growth may outweigh its benefits, resulting in unsustainability. Basically, in a wide range of circumstances, long term economic growth is unsustainable due to increasing environmental damage. Nevertheless, the model has many options that can be explored by policy makers, to make the development path more sustainable, as advocated by sustainomics. One example suggests that government supported abatement programs are needed to move towards sustainable development, since the model runs without abatement were infeasible. The optimal rate of abatement increases over time. Abatement of pollution is necessary to improve ecosystem viability and increase sustainability. Further research is necessary to seek conditions under which alternative economic growth paths are likely to become sustainable.

    To safely and effectively apply artemisinin sustained-release granules to control and prevent algal water-blooms, the effects of artemisinin and its sustained-release granules on freshwater alga (Scenedesmus obliquus (S. obliquus) and Microcystis aeruginosa (M. aeruginosa)), as well as the production and release of microcystins (MCs) were studied. The results showed that artemisinin sustained-release granules inhibited the growth of M. aeruginosa (above 95% IR) and S. obliquus (about 90% IR), with M. aeruginosa more sensitive. The artemisinin sustained-release granules had a longer inhibition effect on growth of pure algae and algal coexistence than direct artemisinin dosing. The artemisinin sustained-release granules could decrease the production and release of algal toxins due to the continued stress of artemisinin released from artemisinin sustained-release granules. There was no increase in the total amount of MC-LR in the algal cell culture medium.

    Full Text Available Economic growth is one of the most important issues of humanity. Both in national economies and world economy, recession and prosperity periods are regularly succeeding with different amplitudes. But beyond these fluctuations and their effects, the results are important: performance and economic growth. Because of the problematical issue of economic growth, the authors are trying to critically reflect on the economic growth concept and on its implications on the praxis area. Although there is a large literature about economic growth modeling, it is intriguing that there still are some serious obstacles for conceptualization and praxis. Only the simple fact that the economic growth process needs serious thinking on the time dimension is sufficient for understanding the real difficulties of this problematical issue. As for the economic growth praxis, a clear analysis of the interests system within an economy is needed. Without trying to find miraculous solutions for the economic growth issue, the authors suggest a clear and correct analysis of this important subject.

  1. Microfoundations for Sustainable Growth with Eco-Intelligent Product Service-Arrangements

    Directory of Open Access Journals (Sweden)

    Najine Ameli

    2013-03-01

    Full Text Available This paper argues that the contemporary growth paradigm needs to be reconsidered on a micro level of consumption and product service-systems. This becomes necessary since a dynamic link between macro strategies and micro implementation of sustainable growth is missing up to date. Therefore, mainstream sustainability strategies of efficiency and consistency are extended by sufficiency in order to integrate strategies for individual welfare within their social environment. Limits to and drivers for growth are revised and updated socially in terms of qualitative values, diminishing marginal utility or symbolic social distinction. We elaborate a definition of sustainable growth that fosters individual welfare by enhancing social enactment within the boundaries of environmental space. Shifting focus on social aspects in design fosters more sustainable production and consumption patterns while sustaining individual welfare. We derive latent indications for eco-intelligent product service-arrangements and evaluate to concepts by referring to introduced definitions and according indications. With doing so, we illustrate new pathways for the translation of sustainable growth and strategies into product service-systems.

    2017-08-01

    Full Text Available Nigeria is currently facing economic growth and development challenge. The economic challenge is occasioned by mono-cultural economic reliance on the single resource of crude oil export revenue as well as other internal and international effects that affect her economic drive for heightened growth and development. The Nigerian government had over the years searched for ways of diversifying its economy for greater growth and development especially given the various challenges in the economy, mainly the steep reduction in crude oil revenue arising from volatility of global oil price. This paper therefore uses the research methodology of case study to do a holistic assessment of the possibility of Nigeria diversifying into her tourism potentials for economic growth and development. This would be done equally by drawing relevant comparative analysis of other countries bringing economic benefits in Africa and across the globe.

    Full Text Available Business enterprises exist in a world that is fiercely competitive, tied with huge global uncertainties. They always encounter increasing pressure on prices and margins. Hence, irrespective of their domain of operations and industry, businesses are naturally concerned about their growth, specifically sustained profitable growth, in today’s world. Marketing is a key business function to market and lead a business towards sustained profitable growth but the problem is it lacks a systems perspective in its operations, strategy, and practice. Further, given the confluence and systemic interactions of various economic, digital, and competitive forces; the challenge for different business functions—including marketing—increases tremendously. In this context, it is important for business enterprises to have a systems perspective to find their ways to growth that will be sustained. This calls for a holistic approach to assimilate and steer the business functions in any enterprise. The present conceptual paper focuses on an important business function for sustained growth in a holistic way and presents a systems model, called ‘Value Based Business Approach (VBBA-marketing’, which has potential to guide and steer companies and business enterprises to create a path for their sustained profitable growth.

    Full Text Available What is economic growth? Although the answer to this question may seems of real simplicity, developing an accurate definition of this concept may constitute a real challenge both from a theoretical but also empirical point of view. This constant debate upon the concept of economic growth as well as indentifying the optimum set of instruments for quantifying it, constituted the starting point of the current article. The concept of economic growth is used nowadays complementary to terms like economic development, economic welfare or economic progress with reference to this complex process that implies macro-scale structures. Moreover indentifying the main factors that generate a significant impact upon the dynamics of the economic growth process, constitute a useful approach taking into consideration the high degree of heterogeneity that characterize the architecture of the economies around the world. If we develop this analysis across the European Union member states this debate became even more challenging due to the high degree of diversity that characterize these economies. Moreover, the Central and Eastern European countries and especially the ones that joined EU in 2004 and 2007 embody a set of particularities that make them extremely different from the rest of the European Union member states, features related to the historical background, economic policies and common efforts to intensify the convergence process with the more developed EU members. This paper studies the impact of two main factors upon the economic growth process namely an endogenous-exogenous factor like the degree of openness and an endogenous factor like the human capital using a complex dynamic panel method. The arguments that were in favour of choosing this two factors are on one hand the multitude of theoretical studies that argued the importance of them in modelling the economic growth process and on the other hand the small number of studies that use panel methods in

    Full Text Available We have compared the performance of two Troponin-C-based calcium FRET sensors using fluorescence lifetime read-outs. The first sensor, TN-L15, consists of a Troponin-C fragment inserted between CFP and Citrine while the second sensor, called mTFP-TnC-Cit, was realized by replacing CFP in TN-L15 with monomeric Teal Fluorescent Protein (mTFP1. Using cytosol preparations of transiently transfected mammalian cells, we have measured the fluorescence decay profiles of these sensors at controlled concentrations of calcium using time-correlated single photon counting. These data were fitted to discrete exponential decay models using global analysis to determine the FRET efficiency, fraction of donor molecules undergoing FRET and calcium affinity of these sensors. We have also studied the decay profiles of the donor fluorescent proteins alone and determined the sensitivity of the donor lifetime to temperature and emission wavelength. Live-cell fluorescence lifetime imaging (FLIM of HEK293T cells expressing each of these sensors was also undertaken. We confirmed that donor fluorescence of mTFP-TnC-Cit fits well to a two-component decay model, while the TN-L15 lifetime data was best fitted to a constrained four-component model, which was supported by phasor analysis of the measured lifetime data. If the constrained global fitting is employed, the TN-L15 sensor can provide a larger dynamic range of lifetime readout than the mTFP-TnC-Cit sensor but the CFP donor is significantly more sensitive to changes in temperature and emission wavelength compared to mTFP and, while the mTFP-TnC-Cit solution phase data broadly agreed with measurements in live cells, this was not the case for the TN-L15 sensor. Our titration experiment also indicates that a similar precision in determination of calcium concentration can be achieved with both FRET biosensors when fitting a single exponential donor fluorescence decay model to the fluorescence decay profiles. We therefore

    Full Text Available Smart Growth has become an evident concept in public policy debates and provides answers to the enduring problems of sprawling development and its many adverse consequences. While the concept has widely been touted to promote an urban development pattern characterized by compact and mixed-use development, walkable and bikeable neighborhoods, preserved green spaces, and the availability of mass transit, not much has been written about its contribution to sustainable development. This paper is an attempt to explore the concepts of smart growth and sustainable development and the extent to which the former contributes to the achievement of the latter. The various debates surrounding the smart growth movement have also been explored. The 2003 general plan guideline by the US State of California is used as the basis for determining the sustainable development role of smart growth policies in Portland (Oregon, Arlington (Virginia, Boulder (Colorado and Lancaster County (Pennsylvania. The paper concludes that it would be inappropriate to equate smart growth to sustainable development as the latter is a much broader concept and cuts across myriad disciplines. Notwithstanding, the implementation of smart growth policies in the cases studied have been observed to promote compact, infill and transit-oriented development and to conserve and protect open spaces and natural areas. All these are pro-sustainable development. While this paper has observed that smart growth serves as one of the approaches for achieving sustainable development goals, it calls for a more quantitative study to be able to measure the magnitude of the contribution associated with the smart growth policies.

    The herbicide, glyphosate, has been shown to stimulate growth in a range of species when applied at doses of 5-60 g a.e. ha{sup -1}, corresponding to realistic spray drift events. This study investigates growth of shoot parameters over time to detect whether the glyphosate induced growth increase was sustained and had a final effect on reproduction. The results showed that an actual biomass growth rate increase took place within the first week after spraying with glyphosate doses <60 g a.e. ha{sup -1}. This initial growth boost kept treated plants larger than untreated plants for up to six weeks, but at harvest there was no significant difference between control plants and treated plants. Possible effects of glyphosate hormesis on the competitive ability of spray drift affected plants are discussed. - Glyphosate induced hormesis in barley is not sustained over time.

    Full Text Available India has experienced a robust economic growth in the recent years, but with a trajectory which offers both positive and negative lessons on the business innovation faced by many countries in Asia and elsewhere in the developing world. This study sought to test the relationship between innovation, financial performance and economic growth. Data were analyzed using descriptive and inferential statistics on the factors that contribute to assuring the innovation of the processes involved in the financial performance and economic development in the rubber and plastic product sector in India. The results revealed that there is a positive relationship between innovation and economic growth, as well as between innovation and the financial performance of the company. Finally, the conclusion presents implications, limitations and directions for future research regarding the importance of innovation to the firm’s performance. A clear lesson from this study is that the future must include promoting Innovative Indian SMEs; in other words, business competitiveness depends on the creativity and innovativeness of its entrepreneurship.

    The present debate on how to increase global food production in a sustainable way has focused on arguments over the pros and cons of genetically modified (GM) crops. Scientists in both public and private sectors clearly regard GM technology as a major new set of tools, whereas industry sees it as an opportunity for increased profits. However, it remains questionable whether GM crops can contribute to agricultural growth, agricultural development, and agricultural sustainability. This review p...

  17. Critical Sustainability: Setting the Limits to Growth and Responsibility in Tourism

    Directory of Open Access Journals (Sweden)

    Jarkko Saarinen

    2013-12-01

    Full Text Available The idea of sustainable development has been discussed in tourism research for almost a quarter of a century. During that time, sustainability has become an important policy framework for tourism and regional developers guiding their planning and development thinking. Sustainability has also emerged academically as an important field of research with an emphasis on defining the limits to growth and responsibilities in tourism. However, while there are urgent needs to incorporate sustainability into tourism, there is also a growing amount of frustration among scholars on the conceptual nature of sustainability and how tourism as a private-driven economic activity relates to the ideals of sustainable development. This has created an increasing need to understand and potentially reframe the concept. The purpose of this paper is to overview the conceptual dimensions of sustainable tourism and discuss some of the main sources of frustration. Based on this, it is concluded that while a conceptual plurality seems to be unavoidable, there is a need to re-frame i.e., rescale and decentralize tourism in policy frameworks and practices aiming towards sustainability.

    This study assesses the quantitative impact of parasitic chytrids on the planktonic food web of two contrasting freshwater lakes during different algal bloom situations. Carbon-based food web models were used to investigate the effects of chytrids during the spring diatom bloom in Lake Pavin (oligo-mesotrophic) and the autumn cyanobacteria bloom in Lake Aydat (eutrophic). Linear inverse modeling was employed to estimate undetermined flows in both lakes. The Monte Carlo Markov chain linear inverse modeling procedure provided estimates of the ranges of model-derived fluxes. Model results confirm recent theories on the impact of parasites on food web function through grazers and recyclers. During blooms of "inedible" algae (unexploited by planktonic herbivores), the epidemic growth of chytrids channeled 19-20% of the primary production in both lakes through the production of grazer exploitable zoospores. The parasitic throughput represented 50% and 57% of the zooplankton diet, respectively, in the oligo-mesotrophic and in the eutrophic lakes. Parasites also affected ecological network properties such as longer carbon path lengths and loop strength, and contributed to increase the stability of the aquatic food web, notably in the oligo-mesotrophic Lake Pavin.

    In recent years smart textiles have gained a significant increase of attention. Electrotherapeutic socks, light emitting dresses or shirts with integrated sensors, having the ability to process data of vital parameters, are just a few examples and the full potential is not yet exhausted: Smart textiles are not only used for clothing purposes. Sensors for the care of the elderly, light applications for home textiles and monitoring systems in the automotive section are promising fields for the future. For all these electrical and electronic features, the supply of power is needed. The most common used power supplies, however, are not flexible, often not lightweight and therefore a huge problem for the integration into textile products. In recent projects, textile-based batteries are being developed. Metal-coated fabrics and yarns (e.g. silver, copper, nickel, zinc) as well as carbon based materials were used to create textile based energy sources. This article gives an overview of textile based electrochemical cells by combining different conductive yarns and a gel-electrolyte. The available materials will be processed by embroidering utilizing tailored fiber placement (TFP). The electrical characteristics of different embroidered patterns and material combinations are examined.

  20. SUSTAINABLE GROWTH OF THE COMMERCIAL AVIATION INDUSTRY IN MALAYSIA USING A SYSTEM DYNAMICS APPROACH

    2015-09-01

    Full Text Available The environmental impact of the commercial aviation industry for an emerging economy like Malaysia is under-studied. The focus on the subject has thus far concentrated either on non geographical performance of the aviation industry or technical performance of aircrafts and that leaves the sustainability of the commercial aviation industry for an economy, or more specifically, an emerging economy least understood. Hence, this paper aims to investigate the sustainability of the growth of the commercial aviation industry in Malaysia and its impact upon the environment using a system dynamics approach. VENSIM is employed to model the commercial aviation industry in Malaysia as a dynamic system to evaluate the CO2 emitted from each component within the industry in order to forecast its overall CO2 emission. Results from the analysis show that sustainable growth can be affected by adopting short and long term strategies identified in this study.

  1. In Tourism Industry We Talk About Sustainable Development, But We Evaluate Profits and Growth

    2017-06-01

    Full Text Available Tourism is one of the biggest economic sectors, it has a significant impact on the environment. At the same time, the long-term development of tourism also greatly depends on the environment it affects. Experts are unanimous that it is necessary for the longterm existence and development of tourism that it becomes sustainable. Nevertheless, in tourism businesses, sustainable development strategies are not sufficiently present and put into practice. The author of the article presents the argument as a possible reason for this: the management of tourism enterprises as well as management of all the companies is focused on doing business successfully; and because the performance of management is assessed in terms of growth and security of its operations, and not in relation to the measures taken in the field of sustainable development, management gives priority to ensuring relatively short-term growth and security of operations.

    Full Text Available The paper presents the use of the “time series model” to forecast the quarterly and yearly sales for a company with business seasonality. These sales forecasts will represent the fundamental basis for estimating the external financing, using the percentage to sales method. Sales growth rates are afterwards analysed in the context of ensuring a sustainable and self-financed growth. We focus on establishing the forecasted financial structure of the external financial requirements both in the context of using the reinvested profit complemented with credit, maintaining the debt rate constant, and in the context of total internal funding of the company economic growth, from reinvested profit.

    The quantification of growth and development is an important issue in economics, because these phenomena are closely related to sustainability. We address growth and development from a network perspective in which economic systems are represented as flow networks and analyzed using ecological network analysis (ENA). The Beijing economic system is used as a case study and 11 input-output (I-O) tables for 1985-2010 are converted into currency networks. ENA is used to calculate system-level indices to quantify the growth and development of Beijing. The contributions of each direct flow toward growth and development in 2010 are calculated and their implications for sustainable development are discussed. The results show that during 1985-2010, growth was the main attribute of the Beijing economic system. Although the system grew exponentially, its development fluctuated within only a small range. The results suggest that system ascendency should be increased in order to favor more sustainable development. Ascendency can be augmented in two ways: (1) strengthen those pathways with positive contributions to increasing ascendency and (2) weaken those with negative effects.

  5. Tragedy of the Commons, Business Growth and the Fundamental Sustainability Problem

    2012-09-01

    Full Text Available This paper reviews the major issues involved in Hardin’s [1] tragedy of the commons, written over 44 years ago, and examines whether these issues are still relevant today. We assert that this model still provides important insight to aid in the solution to our global problems. In particular, we maintain that the underlying issues of growth against limits and bounded rationality are still not adequately recognized and addressed; this underlies many of the reasons for our unsustainable world. Examples from fisheries management are used to examine potential solutions and reveal weaknesses in current approaches. We show how our current, restricted mental models promote social injustice and blind us to developing sustainable solutions. Both the neo-liberal economic view of business that directly seeks growth and the new sustainable development view that indirectly supports growth are leading our global economy in the wrong direction and away from prosperity and sustainability. Current thinking has not realized Hardin’s message that sustainability is of the class of no technology solution problems. We conclude with recommendations to radically advance a new world view and business paradigm.

  6. Avoiding the Limits to Growth: Gross National Happiness in Bhutan as a Model for Sustainable Development

    Directory of Open Access Journals (Sweden)

    Jeremy S. Brooks

    2013-08-01

    Full Text Available In their 30-year update to Limits to Growth, Meadows et al. call for a vision of sustainable development that includes systemic change brought on by new perspectives on the purpose of development, new ways of measuring progress, and changes in social norms. Here, I discuss Meadows et al.’s work in the context of the literature on sustainable development and well-being as well as the development trajectory of Bhutan. I suggest that Bhutan’s development approach mirrors Meadows et al.’s recommendations and provides one model for sustainable development. The ideal of maximizing Gross National Happiness (GNH exemplifies Bhutan’s commitment to holistic development and dovetails with arguments about the shortcomings of approaches that emphasize economic growth. I provide examples of how GNH has been put into practice, describe how happiness is being measured, and discuss the emergence of social norms and a shared Bhutanese identity that may contribute to sustainable development. Bhutan’s development success suggests that an alternative to growth-centric development is viable. However, while Bhutan’s standard of living has increased, the country faces challenges, the most important of which may be their ability to manage rising consumption levels. Importantly, other nations have begun measuring well-being and considering similar development approaches.

    2012-09-01

    Full Text Available Abstract This paper presents a computational model that describes the growth of the bone as a function of the proliferation and hypertrophy of chondrocytes in the growth plate. We have included the effects of the mechanical loads on the sizes of the proliferative and hypertrophic areas, the number of proliferative chondrocytes and the final size of the hypertrophic chondrocytes. The validation of the model was performed with experimental data published on other investigations about proximal tibia of rats, subjected to sustained axial stresses of 0.1 MPa, 0.0 MPa, -0.1 MPa and −0.2 MPa. Growth was simulated during 23 days, obtaining numerical errors between 2.77% and 3.73% with respect to experimental growth rates. The results obtained show that the model adequately simulates the behavior of the growth plate and the effect of mechanical loads over its cellular activity.

    Full Text Available This paper examines the growth experience of Indonesia in the years before and after the Asian financial crisis. Particular attention is paid to the relationship between economic growth and petroleum sector’s total factor productivity (TFP. It finds the possibility that post-crisis Indonesian economic growth has ‘recoupled’ with petroleum sector’s TFP – fluctuations in petroleum TFP is directly correlated with fluctuations in economic growth. Further, although keeping Indonesia’s petroleum sector open to fair competition should be the prime policy, the fact regarding resource nationalism might need to be taken into account in designing the policy to develop the productivity of Indonesia’s petroleum sector.

  9. Developing Policy Scenarios for Sustainable Urban Growth Management: A Delphi Approach

    Full Text Available In many parts of the world, a rapid urbanization process is taking place at an unprecedented scale, and its drastic impacts on societies and the environment are evident. To combat the externalities of such rapid, and to a degree uncontrolled, development, many cities around the globe introduced various urban growth management policies. However, policy making—to provide sustainable outcomes, while generating growth opportunities—has been a daunting task for urban administrators. To ease the task, scenario-based planning methods are introduced to produce alternative visions for managing urban growth in sustainable ways by incorporating various socio-environmental issues. However, even though modelling urban growth and associated impacts based on these scenarios have emerged to strengthen and quantify the future of urban policies and related planning actions, this process has a number of glitches. Major issues include the uncertainties associated with the selection of suitable methods to generate scenarios, identify indicators to be used to assess scenarios, evaluate scenarios to prioritize for policy formulation, and assess the impacts of policy scenarios. This paper aims to address the challenge of developing suitable policy scenarios for sustainable urban growth. As for the methodological approach, the study undertakes a thorough review of the literature and current practices, and conducts a two-round Delphi survey—involving experts from public, private and academic sectors specialized in the fields of urban planning, environmental planning, social planning, transportation modelling, and economic development. The expert driven policy scenarios are validated in a local context by comparing findings against the policy options as proposed in the South East Queensland Regional Plan 2017 (Australia. The findings offer valuable guidelines for planners, modellers, and policy makers in adopting suitable methods, indicators, and policy priorities

  10. Effects of Population Growth and Climate Variability on Sustainable Groundwater in Mali, West Africa

    Directory of Open Access Journals (Sweden)

    Alexandra Lutz

    2010-12-01

    Full Text Available Groundwater is increasingly relied on as a source of potable water in developing countries, but factors such as population growth, development, and climate variability, pose potential challenges for ongoing sustainable supply. The effect of these factors on the groundwater system was considered in four scenarios using a numerical model to represent the Bani area of Mali, West Africa. By 2040, population growth, climate variability, and development as urbanization, agriculture, and industry creates scenarios in which groundwater extraction is an increasingly larger percentage of the groundwater system. Consumption from agriculture and industry increases extraction rates from less than 1 to 3.8% of mean annual precipitation, which will likely affect the groundwater system. For instance, concentrated pumping in local areas may result in water level declines. The results of this study contribute to an ongoing evaluation of sustainable groundwater resources in West Africa.

  11. Sharing Economy as a Contributor to Sustainable Growth. An EU Perspective

    Directory of Open Access Journals (Sweden)

    Florin Bonciu

    2016-06-01

    Full Text Available The paper bases its analytical approach on two assumptions: the first refers to a significant change taking place in the contemporary world economy – the phenomenon of multipolarity – and proposes a new concept, that of multi-level manifestation of multipolarity; the second has in view the need of a new model of sustainable economic growth. In the context of these two points of view, the paper analyses the sharing economy as a potential significant contributor to sustainable economic growth. The conclusion of this research is that sharing economy has a huge potential of involving millions or even billions of participants and of capitalizing the existing assets while providing spill over effects in the economy. The authors expect sharing economy to become a form of economic activity that will complement traditional forms of business while generating positive economic, social and environmental effects.

    The worldwide industrialization, which has spread from advanced industrial nations to developing nations via newly industrialized nations, and the expanded international trade have been triggering all kinds of environmental pollution, so the environmental pollution has become an environmental problem of pan-global line. The spread of modern industrial society, which is characterized by mass production and mass consumption, has been polluting an entire earth as well as a relevant area and draining usable natural resources. It has caused discord between evironmentalists - regarding environment - and developmentalists - stressing growth through industralization - to deepen. Joint Working Party on Trade and Environment 0f OECD and Committee on Trade and Environment of WTO, which was established with joint efforts of international community in order to resolve such problems, has suggested new improved methodologies to promote the protection of environment, trade liberalization, and sustainable development, besides the discussion for the establishment of reciprocal supporting relation at the same time. The concept of sustainable development, whose main objects are the protection of environment, economic growth, and social development, is recognized as an alternative program that can settle the deepened discord between developed and developing countries on the surrounding issue of the protection of environment and economic development. Because the past discussion connecting environment and trade was developed around a static analysis, it was not available to consider thoroughly the dynamic environmental effects of trade liberalization. This study started from such a critical mind has developed the theoretical analysis model on endogenous growth in order to study on the reciprocal relation among environment, trade, and growth at the first time. This report examined the reciprocal relation between environment and trade, trade and growth, and growth and environment within

    Plant growth promoting rhizobacteria (PGPR) shows an important role in the sustainable agriculture industry. The increasing demand for crop production with a significant reduction of synthetic chemical fertilizers and pesticides use is a big challenge nowadays. The use of PGPR has been proven to be an environmentally sound way of increasing crop yields by facilitating plant growth through either a direct or indirect mechanism. The mechanisms of PGPR include regulating hormonal and nutritional balance, inducing resistance against plant pathogens, and solubilizing nutrients for easy uptake by plants. In addition, PGPR show synergistic and antagonistic interactions with microorganisms within the rhizosphere and beyond in bulk soil, which indirectly boosts plant growth rate. There are many bacteria species that act as PGPR, described in the literature as successful for improving plant growth. However, there is a gap between the mode of action (mechanism) of the PGPR for plant growth and the role of the PGPR as biofertilizer-thus the importance of nano-encapsulation technology in improving the efficacy of PGPR. Hence, this review bridges the gap mentioned and summarizes the mechanism of PGPR as a biofertilizer for agricultural sustainability.

    2012-01-01

    Full Text Available The neoclassical growth models argued that the movement to steady states; technology, exogenous rate of savings, population growth and technical progress stimulate higher growth levels (Solow 1956. Contrary to the neoclassical argument, endogenous growth model argues that, in the theory of endogenous growth, government play a significant role in promoting accumulation of knowledge, research and development, public investment, human capital development, law and order can generate growth both in the short and long run. Moreover, they assumed technical progress as endogenous variable for growth (Barro 1995. This study analyze the effects of fiscal deficit on sustainability of economic growth and provided new empirical evidence on the effects of fiscal deficit on saving and sustainability of economic growth based on the assumption of endogenous growth model. We estimated using the reduced form of GMM method for dynamic panels covers 1990-2009 for three emerging countries that includes China, India and South Africa.

  16. Does Renewable Energy Drive Sustainable Economic Growth? Multivariate Panel Data Evidence for EU-28 Countries

    2017-03-01

    Full Text Available Energy is crucial to economic progress, but the contemporary worldwide population increase that demands greater energy generated from conventional exhaustible resources, an energy price upsurge, and environmental concerns, imperils sustainable economic growth. Nevertheless, switching to renewable energy produced from naturally replenished resources promotes energy security, likewise addressing issues such as global warming and climate change. This paper aims at exploring the influence and causal relation between renewable energy, both overall and by type, and sustainable economic growth of European Union (EU-28 countries for the period of 2003–2014. We notice that the mean share of renewable energy in the gross final energy consumption is 15%, while the mean share of renewable energy in transport fuel consumption is 3%, which are below the thresholds of 20% and 10%, respectively, as set by the EU Directive 2009/28/EC. By estimating panel data fixed-effects regression models, the results provide support for a positive influence of renewable energy overall, as well as by type, namely biomass, hydropower, geothermal energy, wind power, and solar energy on gross domestic product per capita. However, biomass energy shows the highest influence on economic growth among the rest of renewable energy types. In fact, a 1% increase of the primary production of solid biofuels increases GDP per capita by 0.16%. Besides, cointegrating regressions set on panel fully modified and dynamic ordinary least squares regressions confirm the positive influence related to the primary production of renewable energies on economic growth. A 1% increase in primary production of renewable energies increases GDP per capita by 0.05%–0.06%. However, the results of Granger causality based on panel vector error correction model indicate both in short-run and long-run a unidirectional causal relationship running from sustainable economic growth to the primary production of

    The administration of recombinant human growth hormone in adults with growth hormone deficiency has been known to improve metabolic impairment and quality of life. Patients, however, have to tolerate daily injections of growth hormone. The efficacy, safety, and compliance of weekly administered sustained-release recombinant human growth hormone (SR-rhGH, Declage™) supplement in patients with growth hormone deficiency were evaluated. This trial is 12-week prospective, single-arm, open-label trial. Men and women aged ≥20 years with diagnosed growth hormone deficiency (caused by pituitary tumor, trauma and other pituitary diseases) were eligible for this study. Each subject was given 2 mg (6 IU) of SR-rhGH once a week, subcutaneously for 12 weeks. Efficacy and safety at baseline and within 30 days after the 12th injection were assessed and compared. Score of Assessment of Growth Hormone Deficiency in Adults (AGHDA score) for quality of life and serum IGF-1 level. The IGF-1 level of 108.67±74.03 ng/mL was increased to 129.01±68.37 ng/mL (p=0.0111) and the AGHDA QoL score was decreased from 9.80±6.51 to 7.55±5.76 (p<0.0001) at week 12 compared with those at baseline. Adverse events included pain, swelling, erythema, and warmth sensation at the administration site, but many adverse events gradually disappeared during the investigation. Weekly administered SR-rhGH for 12 weeks effectively increased IGF-1 level and improved the quality of life in patients with GH deficiency without serious adverse events.

    Full Text Available The increasing levels of generation of nutrient-rich waste water pose serious challenge. Conventional biological and chemical methods of waste water treatment have failed in meeting sustainability challenges. Naturally occurring mixed algal species reared in mixotrophic growth modes have been deployed to recover nutrients (N and P from domestic wastewater after anaerobic digestion. In this paper, we present the results pertaining to growth and mixotrophy. Pilot-scale operation shows that the cultivation methods adopted and the use of naturally selected species lead to a tendency among these species to clump at certain stages of growth that in turn float or settle rapidly making algal harvest and thereby the nutrient recovery processes energy efficient. The highest settling rate was found to be 6.37 ± 1.6 g/m2/d. Mixotrophy was seen to contribute 15 – 24 % across the various algal consortia in wastewater (polyculture.

    1997-01-01

    "One of the most sensitive criteria for gauging the degree of socio-economic prosperity of an urban settlement is the ability to sustain stable rates of population growth by attracting newcomers and retaining existing population. The present paper argues that after reaching a particular size (on the average, 20-30,000 residents), urban localities in Israel tend to experience substantial changes in components of their annual population growth. Starting with this inflection point, the growth of settlements gradually becomes less dependent on natural causes (birth and death rates) than on the ability to attract newcomers and retain current residents. On the basis of this conclusion, a strategy of ¿redirecting priorities' to developing the peripheral regions of the country is suggested." excerpt

    Full Text Available The evolution of Chinese economic growth correlates with more or less inclusive politic and economic institutions at different points of history. At 13 century, China stood as the most technologically advanced nation in the world, where economic institutions motivates innovation and trade. In 20th century China experienced some industrialization policy by the regime, the Great Leap Forward, while in the last three decades economic growth has been pushed by an abundant workforce, implementation of economic reforms aimed at the market and promotion of domestic consumption. However, China has driven its economic activity into an authoritarian context, political and economic constraints where we could assume that sustainability of Chinese economic model with high growth rates tends to stagnate in the coming years, if political reforms are not carried out.

  1. Publication Growth in Biological Sub-Fields: Patterns, Predictability and Sustainability

    Directory of Open Access Journals (Sweden)

    Marco Pautasso

    2012-11-01

    Full Text Available Biologists are producing ever-increasing quantities of papers. The question arises of whether current rates of increase in scientific outputs are sustainable in the long term. I studied this issue using publication data from the Web of Science (1991–2010 for 18 biological sub-fields. In the majority of cases, an exponential regression explains more variation than a linear one in the number of papers published each year as a function of publication year. Exponential growth in publication numbers is clearly not sustainable. About 75% of the variation in publication growth among biological sub-fields over the two studied decades can be predicted by publication data from the first six years. Currently trendy fields such as structural biology, neuroscience and biomaterials cannot be expected to carry on growing at the current pace, because in a few decades they would produce more papers than the whole of biology combined. Synthetic and systems biology are problematic from the point of view of knowledge dissemination, because in these fields more than 80% of existing papers have been published over the last five years. The evidence presented here casts a shadow on how sustainable the recent increase in scientific publications can be in the long term.

    Micro-RNAs are deregulated in cancer cells, and some are either tumor suppressive or oncogenic. In addition, a link has been established between decreased expression of micro-RNAs and transformation, and several proteins of the RNA interference pathway have been shown to be haploinsufficient tumor suppressors. Oncogenic micro-RNAs (oncomiRs) could represent new therapeutic targets, and their identification is therefore crucial. However, structural and functional redundancy between micro-RNAs hampers approaches relying on individual micro-RNA inhibition. We reasoned that in cancer cells that depend on oncomiRs, impairing the micro-RNA pathway could lead to growth perturbation rather than increased tumorigenesis. Identifying such cells could allow functional analyses of individual micro-RNAs by complementation of the phenotypes observed upon global micro-RNA inhibition. Therefore, we developed episomal vectors coding for small hairpin RNAs targeting either Drosha or DGCR8, the two components of the microprocessor, the nuclear micro-RNA maturation complex. We identified cancer cell lines in which both vectors induced colony growth arrest. We then screened for individual micro-RNAs complementing this growth arrest, and identified miR-19a, miR-19b, miR-20a and miR-27b as major growth-sustaining micro-RNAs. However, the effect of miR-19a and miR-19b was only transient. In addition, embryonic stem cell-derived micro-RNAs with miR-20a seeds were much less efficient than miR-20a in sustaining cancer cell growth, a finding that contrasted with results obtained in stem cells. Finally, we showed that the tumor suppressor phosphatase and tensin homologue deleted on chromosome 10, a shared target of miR-19 and miR-20, was functionally involved in the growth arrest induced by microprocessor inhibition. We conclude that our approach allowed to identify microprocessor-dependent cancer cells, which could be used to screen for growth-sustaining micro-RNAs. This complementation screen

    Fish growth is strongly influenced by environmental and nutritional factors and changing culture conditions can help optimize it. The importance of early-life experience on the muscle phenotype later in life is well known. Here, we study the effects of 5 weeks of moderate and sustained swimming activity (5 BL s(-1)) in gilthead sea bream during early development. We analysed growth and body indexes, plasma IGF-I and GH levels, feed conversion, composition [proximate and isotopic ((15)N/(13)C)] and metabolic key enzymes (COX, CS, LDH, HOAD, HK, ALAT, ASAT) of white muscle. Moderate and continuous exercise in fingerlings of gilthead sea bream increased plasma IGF-I, whereas it reduced plasma GH. Under these conditions, growth rate improved without any modification to feed intake through an increase in muscle mass and a reduction in mesenteric fat deposits. There were no changes in the content and turnover of muscle proteins and lipid reserves. Glycogen stores were maintained, but glycogen turnover was higher in white muscle of exercised fish. A lower LDH/CS ratio demonstrated an improvement in the aerobic capacity of white muscle, while a reduction in the COX/CS ratio possibly indicated a functional adaptation of mitochondria to adjust to the tissue-specific energy demand and metabolic fuel availability in exercised fish. We discuss the synergistic effects of dietary nutrients and sustained exercise on the different mitochondrial responses.

    The paper outlines the strengths and weaknesses of the U.S. economic growth model, assesses its’ ability to respond to the key economic, environmental and social challenges currently facing the U.S. and proposes policies that if adopted would move the U.S. onto a more sustainable growth path. The paper provides scenarios of projected future growth trajectories, as well as recommendations for specific policies in key areas: employment, infrastructure, energy and fiscal rebalancing. To reach this goal this paper focuses on four areas for action: Increasing employment, which is the most urgent priority to accelerate recovery from the Great Recession, while addressing underlying structural issues that have led to a decade of poor economic outcomes for most citizens; Investing in the future, as the key marker of whether the United States is prepared to make farsighted decisions to improve education, build new infrastructure and increase innovation; Maximizing an increased energy endowment in a way that grows the economy, while reinforcing the trend towards reducing resource demand and reducing greenhouse gas emissions; and, Fiscal rebalancing, where the United States must insulate economic recovery from the process of fiscal reform while reducing and stabilizing debt over the long term. Finally, we argue that President Obama can re-energize America’s global leadership if he builds on a platform of domestic actions that enhance the sustainability of America’s society and economy.

  6. Does Firms’ Innovation Promote Export Growth Sustainably?—Evidence from Chinese Manufacturing Firms

    Full Text Available Recent theoretical analysis and empirical studies have emphasized that firms’ innovation could significantly improve export growth. However, the positive effect of innovation on exports is likely to change due to unstable domestic offsetting for innovation and increasing worldwide competition for trade. This study aims to explore the dynamic link between them. We first develop a theoretical model between innovation and export growth based on the theory of heterogeneity. Export growth is measured through the dimensions of extensive margin and intensive margin so as to better investigate the effect of innovation on export performance. The propositions of mechanism analysis reveal that the effect of innovation on exports is non-linear rather than sustainable. An empirical study is followed to test the propositions by using data from a representative panel of Chinese manufacturing firms. Consistent with the theoretical predictions, the results show an inverted U-shaped relationship between innovation and extensive margin and a U-shaped relationship between innovation and intensive margin. The non-linear relations are verified by a threshold effect test. Further study shows less innovation and more firms on the left side of the relation curves. The distribution suggests irregular innovation ability among the exporters. Moreover, the role of innovation is more important for export growth and the corresponding threshold is higher in terms of high technological sectors. The contribution of this study is to introduce a comprehensive framework to investigate the dynamic effect of innovation on export growth, serving as a modest spur to induce the following studies to explore the sustainability of innovation effect.

    Lymphatics proliferate, become enlarged, or regress in multiple inflammatory lung diseases in humans. Lymphatic growth and remodeling is known to occur in the mouse trachea in sustained inflammation, but whether intrapulmonary lymphatics exhibit similar plasticity is unknown. We examined the time course, distribution, and dependence on vascular endothelial growth factor receptor (VEGFR)-2/VEGFR-3 signaling of lung lymphatics in sustained inflammation. Lymphatics in mouse lungs were examined under baseline conditions and 3 to 28 days after Mycoplasma pulmonis infection, using prospero heomeobox 1-enhanced green fluorescence protein and VEGFR-3 as markers. Sprouting lymphangiogenesis was evident at 7 days. Lymphatic growth was restricted to regions of bronchus-associated lymphoid tissue (BALT), where VEGF-C-producing cells were scattered in T-cell zones. Expansion of lung lymphatics after infection was reduced 68% by blocking VEGFR-2, 83% by blocking VEGFR-3, and 99% by blocking both receptors. Inhibition of VEGFR-2/VEGFR-3 did not prevent the formation of BALT. Treatment of established infection with oxytetracycline caused BALT, but not the lymphatics, to regress. We conclude that robust lymphangiogenesis occurs in mouse lungs after M. pulmonis infection through a mechanism involving signaling of both VEGFR-2 and VEGFR-3. Expansion of the lymphatic network is restricted to regions of BALT, but lymphatics do not regress when BALT regresses after antibiotic treatment. The lung lymphatic network can thus expand in sustained inflammation, but the expansion is not as reversible as the accompanying inflammation.

    Cells are mechanosensitive to extracellular matrix (ECM) deformation, which can be caused by muscle contraction or changes in hydrostatic pressure. Focal adhesions (FAs) mediate the linkage between the cell and the ECM and initiate mechanically stimulated signaling events. We developed a stretching apparatus in which cells grown on fibronectin-coated elastic substrates can be stretched and imaged live to study how FAs dynamically respond to ECM deformation. Human bone osteosarcoma epithelial cell line U2OS was transfected with GFP-paxillin as an FA marker and subjected to sustained uniaxial stretching. Two responses at different timescales were observed: rapid FA growth within seconds after stretching, and delayed FA disassembly and loss of cell polarity that occurred over tens of minutes. Rapid FA growth occurred in all cells; however, delayed responses to stretch occurred in an orientation-specific manner, specifically in cells with their long axes perpendicular to the stretching direction, but not in cells with their long axes parallel to stretch. Pharmacological treatments demonstrated that FA kinase (FAK) promotes but Src inhibits rapid FA growth, whereas FAK, Src, and calpain 2 all contribute to delayed FA disassembly and loss of polarity in cells perpendicular to stretching. Immunostaining for phospho-FAK after stretching revealed that FAK activation was maximal at 5 s after stretching, specifically in FAs oriented perpendicular to stretch. We hypothesize that orientation-specific activation of strain/stress-sensitive proteins in FAs upstream to FAK and Src promote orientation-specific responses in FA growth and disassembly that mediate polarity rearrangement in response to sustained stretch.

    Macroalgae (seaweeds) are the subject of increasing interest for their potential as a source of valuable, sustainable biomass in the food, feed, chemical and pharmaceutical industries. Compared with microalgae, the pace of knowledge acquisition in seaweeds is slower despite the availability of whole-genome sequences and model organisms for the major seaweed groups. This is partly a consequence of specific hurdles related to the large size of these organisms and their slow growth. As a result, this basic scientific field is falling behind, despite the societal and economic importance of these organisms. Here, we argue that sustainable management of seaweed aquaculture requires fundamental understanding of the underlying biological mechanisms controlling macroalgal life cycles - from the production of germ cells to the growth and fertility of the adult organisms - using diverse approaches requiring a broad range of technological tools. This Viewpoint highlights several examples of basic research on macroalgal developmental biology that could enable the step-changes which are required to adequately meet the demands of the aquaculture sector. © 2017 The Authors.

  13. Four Sustainability Goals in a Swedish Low-Growth/Degrowth Context

    Directory of Open Access Journals (Sweden)

    2016-10-01

    Full Text Available Continual environmental degradation and an unfair distribution of environmental burdens and benefits are two great challenges for humanity. Economic growth is often taken for granted when planning for the future. However, it is often argued that maintaining economic growth conflicts with keeping human activities adjusted to ecological boundaries and finite resources, at least for the more-developed countries. With this paper, we present sustainability goals for building and planning in Sweden to be achieved by 2050 in a context of limited or even negative economic growth. These goals should ensure that all groups in society have sufficient resources and a good life within planetary boundaries. We select four goals in a participatory process: two environmental goals related to climate change and land use and two social goals related to welfare and participation. Our results show that achieving the environmental goals will require significant reductions of Sweden’s greenhouse gas (GHG emissions and land use compared to today’s levels. Regarding the social goals, these are, in many aspects, reasonably well fulfilled in Sweden today, although disparities remain between groups of citizens. The main challenge, however, is to ensure that these goals are fulfilled even within environmental limits and if economic growth should halt.

    Full Text Available Stockpiled soils are excavated from the ground during mining activities, and piled on the surface of the soil for rehabilitation purposes. These soils are often characterized by low organic matter (SOM content, low fertility, and poor physical, chemical, and biological properties, limiting their capability for sustainable vegetation growth. The aim of the study was to evaluate the impact of stockpile soils of differing depth and quality on vegetation growth and productivity. Soils were collected at three different depths (surface, mid, and deep as well as mixed (equal proportion of surface, mid and deep from two stockpiles (named Stockpile 1: aged 10 and Stockpile 2: 20 years at the coal mine near Witbank in the Mpumalanga province of South Africa. Soils were amended with different organic and inorganic fertilizer. A 2 × 4 × 5 factorial experiment in a completely randomized blocked design with four replications was established under greenhouse conditions. A grass species (Digiteria eriantha was planted in the pots with unamended and amended soils under greenhouse conditions at 26–28 °C during the day and 16.5–18.5 °C at night. Mean values of plant height, plant cover, total fresh biomass (roots, stems and leaves, and total dry biomass were found to be higher in Stockpile 1 than in Stockpile 2 soils. Plants grown on soils with no amendments had lower mean values for major plant parameters studied. Soil amended with poultry manure and lime was found to have higher growth rate compared with soils with other soil amendments. Mixed soils had better vegetation growth than soil from other depths. Stockpiled soils in the study area cannot support vegetation growth without being amended, as evidenced by low grass growth and productivity in this study.

    Swimming exercise at optimal speed may optimize growth performance of yellowtail kingfish in a recirculating aquaculture system. Therefore, optimal swimming speeds (U opt in m s(-1) or body lengths s(-1), BL s(-1)) were assessed and then applied to determine the effects of long-term forced and sustained swimming at U opt on growth performance of juvenile yellowtail kingfish. U opt was quantified in Blazka-type swim-tunnels for 145, 206, and 311 mm juveniles resulting in values of: (1) 0.70 m s(-1) or 4.83 BL s(-1), (2) 0.82 m s(-1) or 3.25 BL s(-1), and (3) 0.85 m s(-1) or 2.73 BL s(-1). Combined with literature data from larger fish, a relation of U opt (BL s(-1)) = 234.07(BL)(-0.779) (R (2) = 0.9909) was established for this species. Yellowtail kingfish, either forced to perform sustained swimming exercise at an optimal speed of 2.46 BL s(-1) ("swimmers") or allowed to perform spontaneous activity at low water flow ("resters") in a newly designed 3600 L oval flume (with flow created by an impeller driven by an electric motor), were then compared. At the start of the experiment, ten fish were sampled representing the initial condition. After 18 days, swimmers (n = 23) showed a 92% greater increase in BL and 46% greater increase in BW as compared to resters (n = 23). As both groups were fed equal rations, feed conversion ratio (FCR) for swimmers was 1.21 vs. 1.74 for resters. Doppler ultrasound imaging showed a statistically significant higher blood flow (31%) in the ventral aorta of swimmers vs. resters (44 ± 3 vs. 34 ± 3 mL min(-1), respectively, under anesthesia). Thus, growth performance can be rapidly improved by optimal swimming, without larger feed investments.

    Sarcoma accounts for 20% of solid tumors in children. Surgery has significant morbidity. We hypothesized that delivering chemotherapy directly into tumors through sustained release silk systems could slow tumor growth. Human Ewing sarcoma cells A673 were cultured with vincristine and doxorubicin to determine half maximal inhibitory concentration (IC50). Cells were injected into mouse hind leg to create orthotopic tumors. Tumor volumes were measured using ultrasound. When volume reached >250mm(3,) interventions included: implantation of drug-free silk foam (Control-F), doxorubicin 400μg foam (Dox400-F), vincristine 50μg foam (Vin50-F), drug-free silk gel (Control-G), vincristine 50μg gel (Vin50-G), or single dose intravenous vincristine 50μg (Vin50-IV). End-point was volume>1000mm(3). Kaplan Meier and ANOVA were used. IC50 for vincristine and doxorubicin was 0.5ng/mL and 200ng/mL, respectively. There was no difference between Dox400-F [6±1days to end point (DTEP)] and Control-F (5±1.3 DTEP). Vin50-F (12.4±3.5 DTEP) had slower growth compared to Control-F (pinside the sarcoma tumor with silk gel decreased tumor growth. Applying this intratumoral treatment strategy may potentially decrease the extent of surgical excision. Copyright © 2016 Elsevier Inc. All rights reserved.

    Alginate microcapsules coated with a permselective poly-L-ornithine (PLO) membrane have been investigated for the encapsulation and transplantation of islets as a treatment for type 1 diabetes. The therapeutic potential of this approach could be improved through local stimulation of microvascular networks in order to meet mass transport demands of the encapsulated cells. Fibroblast growth factor-1 (FGF-1) is a potent angiogenic factor with optimal effect occurring when it is delivered in a sustained manner. In this paper, a technique is described for the generation of multilayered alginate microcapsules with an outer alginate layer that can be used for the delivery of FGF-1. The influence of alginate concentration and composition (high mannuronic acid (M) or guluronic acid (G) content) on outer layer size and stability, protein encapsulation efficiency, and release kinetics was investigated. The technique results in a stable outer layer of alginate with a mean thickness between 113–164 µm, increasing with alginate concentration and G-content. The outer layer was able to encapsulate and release FGF-1 for up to thirty days, with 1.25% of high G alginate displaying the most sustained release. The released FGF-1 retained its biologic activity in the presence of heparin, and the addition of the outer layer did not alter the permselectivity of the PLO coat. This technique could be used to generate encapsulation systems that deliver proteins to stimulate local neovascularization around encapsulated islets. PMID:20725969

    Vascularization of engineered or damaged tissues is essential to maintain cell viability and proper tissue function. Revascularization of the left ventricle (LV) of the heart after myocardial infarction is particularly important, since hypoxia can give rise to chronic heart failure due to inappropriate remodeling of the LV after death of cardiomyocytes (CMs). Fibroblasts can express vascular endothelial growth factor (VEGF), which plays a major role in angiogenesis and also acts as a chemoattractant and survival factor for CMs and cardiac progenitors. In this in vitro model study, mouse NIH 3T3 fibroblasts encapsulated in 2% w/v Ca-alginate were shown to remain viable for 150 days. Semiquantitative reverse transcription–polymerase chain reaction and immunohistochemistry demonstrated that over 21 days of encapsulation, fibroblasts continued to express VEGF, while enzyme-linked immunosorbent assay showed that there was sustained release of VEGF from the Ca-alginate during this period. The scaffold degraded gradually over the 21 days, without reduction in volume. Cells released from the Ca-alginate at 7 and 21 days as a result of scaffold degradation were shown to retain viability, to adhere to fibronectin in a normal manner, and continue to express VEGF, demonstrating their potential to further contribute to maintenance of cardiac function after scaffold degradation. This model in vitro study therefore demonstrates that fibroblasts encapsulated in Ca-alginate provide sustained release of VEGF. PMID:23082964

    Full Text Available Most innovation activities that are inevitable for sustainable growth are coordinated via research and development (R&D projects, which can differ widely in terms of both project and open innovation characteristics, even when conducted within the same firm. Therefore, it is important to consider the peculiarities of R&D projects when evaluating the performance of open innovation strategies, as well as to explore how the benefits and costs of open innovation are shaped by cross-level interactions. This study identifies the differences between successful and unsuccessful open innovation projects, in both firm-level and project-level terms. We focus on small and medium enterprises (SMEs, which usually lack the full set of internal resources and competences required to effectively develop, produce, and commercialize their innovations, and thus must adopt open innovation approaches more actively for sustainability. Adopting an empirical approach, we conducted a survey of 517 Korean SMEs and analyzed 241 successful and unsuccessful open innovation projects in depth. By combining measurements at the firm and project levels, this study provides new insight into the intra-organizational challenges of implementing open innovation projects, which are not only helpful to strategic decision-makers in SMEs, but also to those who make policies for them.

    The progression of life in all forms is not only dependent on agricultural and food security but also on the soil characteristics. The dynamic nature of soil is a direct manifestation of soil microbes, bio-mineralization, and synergistic co-evolution with plants. With the increase in world's population the demand for agriculture yield has increased tremendously and thereby leading to large scale production of chemical fertilizers. Since the use of fertilizers and pesticides in the agricultural fields have caused degradation of soil quality and fertility, thus the expansion of agricultural land with fertile soil is near impossible, hence researchers and scientists have sifted their attention for a safer and productive means of agricultural practices. Plant growth promoting rhizobacteria (PGPR) has been functioning as a co-evolution between plants and microbes showing antagonistic and synergistic interactions with microorganisms and the soil. Microbial revitalization using plant growth promoters had been achieved through direct and indirect approaches like bio-fertilization, invigorating root growth, rhizoremediation, disease resistance etc. Although, there are a wide variety of PGPR and its allies, their role and usages for sustainable agriculture remains controversial and restricted. There is also variability in the performance of PGPR that may be due to various environmental factors that might affect their growth and proliferation in the plants. These gaps and limitations can be addressed through use of modern approaches and techniques such as nano-encapsulation and micro-encapsulation along with exploring multidisciplinary research that combines applications in biotechnology, nanotechnology, agro biotechnology, chemical engineering and material science and bringing together different ecological and functional biological approaches to provide new formulations and opportunities with immense potential.

    Here we show the extent to which the expected world population growth could be lowered by successfully implementing the recently agreed-upon Sustainable Development Goals (SDGs). The SDGs include specific quantitative targets on mortality, reproductive health, and education for all girls by 2030, measures that will directly and indirectly affect future demographic trends. Based on a multidimensional model of population dynamics that stratifies national populations by age, sex, and level of education with educational fertility and mortality differentials, we translate these goals into SDG population scenarios, resulting in population sizes between 8.2 and 8.7 billion in 2100. Because these results lie outside the 95% prediction range given by the 2015 United Nations probabilistic population projections, we complement the study with sensitivity analyses of these projections that suggest that those prediction intervals are too narrow because of uncertainty in baseline data, conservative assumptions on correlations, and the possibility of new policies influencing these trends. Although the analysis presented here rests on several assumptions about the implementation of the SDGs and the persistence of educational, fertility, and mortality differentials, it quantitatively illustrates the view that demography is not destiny and that policies can make a decisive difference. In particular, advances in female education and reproductive health can contribute greatly to reducing world population growth.

    The peripheral axonal branch of primary sensory neurons readily regenerates after peripheral nerve injury, but the central branch, which courses in the dorsal columns of the spinal cord, does not. However, if a peripheral nerve is transected before a spinal cord injury, sensory neurons that course in the dorsal columns will regenerate, presumably because their intrinsic growth capacity is enhanced by the priming peripheral nerve lesion. As the effective priming lesion is made before the spinal cord injury it would clearly have no clinical utility, and unfortunately, a priming lesion made after a spinal cord injury results in an abortive regenerative response. Here, we show that two priming lesions, one made at the time of a spinal cord injury and a second 1 week after a spinal cord injury, in fact, promote dramatic regeneration, within and beyond the lesion. The first lesion, we hypothesize, enhances intrinsic growth capacity, and the second one sustains it, providing a paradigm for promoting CNS regeneration after injury. primary afferents | dorsal columns | neurite outgrowth | sprouting | priming

    Full Text Available Earth observation data can provide valuable assessments for monitoring the spatial extent of (unsustainable urban growth of the world’s cities to better inform planning policy in reducing associated economic, social and environmental costs. Western Australia has witnessed rapid economic expansion since the turn of the century founded upon extensive natural resource extraction. Thus, Perth, the state capital of Western Australia, has encountered significant population and urban growth in response to the booming state economy. However, the recent economic slowdown resulted in the largest decrease in natural resource values that Western Australia has ever experienced. Here, we present multi-temporal urban expansion statistics from 1990 to 2015 for Perth, derived from Landsat imagery. Current urban estimates used for future development plans and progress monitoring of infill and density targets are based upon aggregated census data and metrics unrepresentative of actual land cover change, underestimating overall urban area. Earth observation provides a temporally consistent methodology, identifying areal urban area at higher spatial and temporal resolution than current estimates. Our results indicate that the spatial extent of the Perth Metropolitan Region has increased 45% between 1990 and 2015, over 320 km2. We highlight the applicability of earth observation data in accurately quantifying urban area for sustainable targeted planning practices.

    Full Text Available Why public debts are growing so fast in most developing countries, like a dangerous snowball which is growing and growing and no one can stop it? It is only a negative relation between high debt and real growth of economy? How can we definitively remove the Ricardian anxiety which called debt a “terrible scourge”? These are only few questions asked in the last century in relation with debt “overhang” not only by scholars, but by governments as well. This paper aims to answer to other questions like: Why debt’s rate grows faster than GDP? Why governments borrow? For current spending or for public investments? Who should benefits current loans? Who should pay for them and when? How should be the taxation along the economic cycle: neutral or countercyclical? Need we a model to sustain the public debt over generations, or it is good enough to maintain a good ration between real GDP growth and debt and that’s it?

    Full Text Available In Malaysia, the growth of the Islamic financial industry has increased tremendously in line with the Government’s ambition to make Malaysia as an international hub for Islamic finance since 2010. With the increasing number of foreign players in this industry plus with the increasing demand from domestic and foreign customers would further enhance the possibility for Malaysia to achieve this ambition. Currently, according to the Economic Transformation Programme, 2012 Malaysia is the world’s third largest market for Shariah assets that cover Islamic banks, Takaful, and sukuk. Malaysia as one of the main contributors to the global Islamic financial assets with Islamic assets in Malaysia grew by 23.8% in 2011 from RM350.8bil to RM434.6bil. The issues of predicting the performance and the survival of Islamic Banks in Malaysia become amongst crucial issues in academic research. By employing multi – layer perceptron neural network and pooled regression, we found that total assets/ size of the Islamic banks (GROWTH have high weightage and significantly influence in predicting the performance and the survival of Islamic banks in Malaysia. With the increasing number of Islamic banking institutions in Malaysia, this study can give insight on the sustainability of the Islamic banking system in Malaysia for the benefit of the investors, shareholder and depositors.

  9. Energy efficiency, human behavior, and economic growth: Challenges to cutting energy demand to sustainable levels

    Increasing energy efficiency in households, transportation, industries, and services is an important strategy to reduce energy service demand to levels that allow the steep reduction of greenhouse gases, and a full fledged switch of energy systems to a renewable basis. Yet, technological efficiency improvements may generate so-called rebound effects, which may `eat up' parts of the technical savings potential. This article provides a comprehensive review of existing research on these effects, raises critiques, and points out open questions. It introduces micro-economic rebound effect and suggests extending consumer-side analysis to incorporate potential `psychological rebound effects.' It then discusses meso-economic rebound effects, i.e. producer-side and market-level rebounds, which so far have achieved little attention in the literature. Finally, the article critically reviews evidence for macro-economic rebound effects as energy efficiency-induced economic growth impacts. For all three categories, the article summarizes assessments of their potential quantitative scope, while pointing out remaining methodological weaknesses and open questions. As a rough "rule of thumb", in the long term and on gross average, only half the technical savings potential of across-the-board efficiency improvements may actually be achieved in the real world. Policies that aim at cutting energy service demand to sustainable levels are well advised to take due note of detrimental behavioral and economic growth impacts, and should foster policies and measures that can contain them.

    A growth accounting exercise is conducted for 88 countries for 1960-94 to examine the source of cross-country differences in total factor productivity (TFP) levels. Two differences distinguish this analysis from that of the related literature. First, the critical technology parameter - the share of physical capital in output - is econometrically estimated and the usual assumption of identical technology across regions is relaxed. Second, while the few studies on the determinants of cross-coun...

    Full Text Available Swimming exercise at optimal speed may optimize growth performance of yellowtail kingfish in a recirculating aquaculture system. Therefore, optimal swimming speeds (Uopt in m s-1 or body lengths s-1, BL s-1 were assessed and then applied to determine the effects of long-term forced and sustained swimming at Uopt on growth performance of juvenile yellowtail kingfish. Uopt was quantified in Blazka-type swim-tunnels for 145 mm, 206 mm and 311 mm juveniles resulting in values of: 1 0.70 m s-1 or 4.83 BL s-1, 2 0.82 m s-1 or 3.25 BL s-1 and 3 0.85 m s-1 or 2.73 BL s-1. Combined with literature data from larger fish, a relation of Uopt (BL s-1 = 234.07(BL-0.779 (R2= 0.9909 was established for this species. Yellowtail kingfish, either forced to perform sustained swimming exercise at an optimal speed of 2.46 BL s-1 (‘swimmers’ or allowed to perform spontaneous activity at low water flow (‘resters’ in a newly designed 3,600 L oval flume (with flow created by an impeller driven by an electric motor, were then compared. At the start of the experiment, ten fish were sampled representing the initial condition. After 18 days, swimmers (n= 23 showed a 92% greater increase in BL and 46% greater increase in BW as compared to resters (n= 23. As both groups were fed equal rations, feed conversion ratio (FCR for swimmers was 1.21 vs. 1.74 for resters. Doppler ultrasound imaging showed a statistically significant higher blood flow (31% in the ventral aorta of swimmers vs. resters (44 ± 3 mL min-1 vs. 34 ± 3 mL min-1, respectively, under anesthesia. Thus growth performance can be rapidly improved by optimal swimming, without larger feed investments.

    Full Text Available Considering the current emerging demographic, urbanization and climatic trends, integrating sustainability and resilience principles into urban development becomes a key priority for decision-makers worldwide. Local and national governments, project developers and other urban stakeholders dealing with the complexities of urban development need projects with clear structure and outcomes in order to inform decision-making and ensure sources of financing. The need for developing an integrated assessment methodology that would capture and quantify multiple urban sustainability and resilience benefits of projects in one common framework and eventually lead to verifiable sustainability and resilience outcomes is immense and challenging at the same time. The main objective of this paper is to present the development of a methodological approach that aims to integrate sustainability and resilience benefits, derived from the implementation of green growth urban projects, into a unified framework of criteria addressing environmental, social, economic and institutional perspectives. The proposed sustainability and resilience benefits assessment (SRBA methodology is a combination of top down and bottom up approaches, including GIS-based scenario building. The different types of sustainability and resilience benefits of urban green growth projects are also identified at different levels (i.e., individual, neighborhood, city and global. Moreover, the proposed methodology creates scenarios that can be illustrated by a map-based approach to enable a better illustration and visualization of benefits. It demonstrates how a map-based approach can assess not only the extent of sustainability and resilience benefits accrued (how much is benefitted, but also their spatial distribution (who is benefitted. The main methodological challenges and issues on developing an integrated sustainability and resilience benefits assessment are identified and discussed.

  15. Stringent Mitigation Policy Implied By Temperature Impacts on Economic Growth

    2014-12-01

    Integrated assessment models (IAMs) compare the costs of greenhouse gas mitigation with damages from climate change in order to evaluate the social welfare implications of climate policy proposals and inform optimal emissions reduction trajectories. However, these models have been criticized for lacking a strong empirical basis for their damage functions, which do little to alter assumptions of sustained GDP growth, even under extreme temperature scenarios. We implement empirical estimates of temperature effects on GDP growth-rates in the Dynamic Integrated Climate and Economy (DICE) model via two pathways, total factor productivity (TFP) growth and capital depreciation. Even under optimistic adaptation assumptions, this damage specification implies that optimal climate policy involves the elimination of emissions in the near future, the stabilization of global temperature change below 2°C, and a social cost of carbon (SCC) an order of magnitude larger than previous estimates. A sensitivity analysis shows that the magnitude of growth effects, the rate of adaptation, and the dynamic interaction between damages from warming and GDP are three critical uncertainties and an important focus for future research.

    Full Text Available AIM: To design and investigate the efficacy of a modified nanostructured lipid carrier loaded with genistein (Gen-NLC to inhibit human lens epithelial cells (HLECs proliferation. METHODS: Gen-NLC was made by melt emulsification method. The morphology, particle size (PS, zeta potentials (ZP, encapsulation efficiency (EE and in vitro release were characterized. The inhibition effect of nanostructured lipid carrier (NLC, genistein (Gen and Gen-NLC on HLECs proliferation was evaluated by cell counting kit-8 (CCK-8 assay, gene and protein expression of the proliferation marker Ki67 were evaluated with real-time quantitative polymerase chain reaction (RT-qPCR and immunofluorescence analyses. RESULTS: The mean PS of Gen-NLC was 80.12±1.55 nm with a mean polydispersity index of 0.11±0.02. The mean ZP was -7.14±0.38 mV and the EE of Gen in the nanoparticles was 92.3%±0.73%. Transmission electron microscopy showed that Gen-NLC displayed spherical-shaped particles covered by an outer-layer structure. In vitro release experiments demonstrated a prolonged drug release for 72h. The CCK-8 assay results showed the NLC had no inhibitory effect on HLECs and Gen-NLC displayed a much more prominent inhibitory effect on cellular growth compared to Gen of the same concentration. The mRNA and protein expression of Ki67 in LECs decreased significantly in Gen-NLC group. CONCLUSION: Sustained drug release by Gen-NLCs may impede HLEC growth.

    Full Text Available The educational system will need to direct its actions and programs towards the identification of the current and future values of the labour market, starting from the existing and potential labour resources, anticipating first and foremost the adjusting of the economy to fast-developing fields and domains, put forward by the State via the Fast-developing Field Strategies or even via the Fast-developing National Strategy. It will accordingly generate a binder between the demands of the labour market as a response to the developing necessities of the economy, and the training/specialization of the labour force as offered by the national syllabus. By these means the educational system would create a labour force compatible with the labour market, which is both a premiss for the increasing level of employment and for the sustainable economic growth. Our task is therefore to provide a concept of education related to technological progress, based on the model of Nelson and Phelps, and a suggestion for investments and education policies.

    Full Text Available Recently, innovative changes in information technology (IT trends, such as cloud computing and deep learning, have led IT companies to focus on collaboration for sustainable growth. This paper investigates collaboration strategies and success factors for IT service companies via a survey-based empirical study of Korean leading IT firms. Four types of collaboration were identified by considering the types of customer relationship and the target market: offshore, joint venture, collaboration with small and medium-sized enterprises (SMEs, and partnership with major local firms. Then, based on a Plan-Do-See management activity process, this paper considers success factors in the planning process and collaboration process, and analyzes an impact of these factors on collaboration performance such as financial performance, process innovation, improving competitiveness, and technology acquisition. As a result, the success factors differ according to the types of performance measures as well as the collaboration types. In particular, the characteristics of partners positively influence competitiveness in captive and global markets, while they improve process innovation in open and domestic markets. This study attempts to provide insight for companies in the IT service industry about how collaboration activities could enhance performance, depending on the alliance types.

    2009-07-01

    Full Text Available The fact that today’s activities are imposing a heavy burden on the earth's capacity has led to an increasing interest in environmental issues. It is emphasized that rapid production growth has exhausted natural resources and polluted the environment. The objective of this essay is to offer a clear definition of natural capital, connect it to a qualitative concept of sustainability and, supported by two analytical models and a set of studies on related environmental literature, to show that sustainability can be attained via imposition of controls over production processes that use depletable natural resources and generate pollution. The methodology used contemplates an integrative approach combining a qualitative (seeking definitions-analytical (appraising models apparatus to reach a new conceptual perspective to conceive sustainability. As the main essay’s contribution, it is showed that sustainability can be reached if compensation is allowed for, i.e., stocks of renewable being augmented as production depletes the stocks of nonrenewable natural resources. Moreover, that result is possible even considering nondecreasing output production, an important finding to contrast with the current environmentally based output growth literature, which asserts that slowing down output production is the only way to obtain sustainability.

  20. Divergent Developmental Trajectories and Strategic Coupling in the Pearl River Delta: Where Is a Sustainable Way of Regional Economic Growth?

    Directory of Open Access Journals (Sweden)

    Yi Liu

    2017-10-01

    Full Text Available This paper interprets regional economic sustainability in the context of the globalization of late-coming regions. Drawing upon the concept of strategic coupling from economic geography, this paper proposes two types of strategic coupling, captive and proactive coupling, for better understanding regional sustainability and resilience through the experiences of the Pearl River Delta in China. It finds that sub-regional economies under captive coupling become highly dependent on exogenous growth and are vulnerable to external shocks. This trajectory looks less sustainable according to the general understanding, but it interestingly shows better resilience during and after the 2008 global financial crisis. In contrast, the ones under proactive coupling are less volatile, but growing much slower and are less resilient. By reporting these regional economic dynamics, this paper argues that sustainability in late-coming regions cannot be explained by either intra-regional forces or the means of global integration alone. In contrast, it has to be explained by the combination of both; the alleged strategic coupling in which economic growth and learning happens. This paper thus calls for greater attention to strategic coupling, the trade-off of globalization and resilience for understanding regional sustainability, rather than purely focusing on resource utilization and ecological balance.

    Full Text Available Sustainable growth is not only the ultimate goal of business corporations but also the primary target of local governments as well as regional and global economies. One of the cornerstones of sustainable growth is ethics. An ethical organizational culture provides support to achieve sustain- able growth. Ethical leaders and employees have great potential for positive influence on decisions and behaviors that lead to sustainability. Ethical behavior, therefore, is expected of everyone in the modern workplace. As a result, companies devote many resources and training programs to make sure their employees live according to the high ethical standards. This study provides an analysis of Vietnamese business students’ level of ethical maturity based on gender, education, work ex- perience, and ethics training. The results of data from 260 business students compared with 704 working adults in Vietnam demonstrate that students have a significantly higher level of ethical maturity. Furthermore, gender and work experience are significant factors in ethical maturity. While more educated respondents and those who had completed an ethics course did have a higher level of ethical maturity, the results were not statistically significant. Analysis of the results along with suggestions and implications are provided.

    Full Text Available Land use, urban development and environmental sustainability have become an interesting research arena as urban development would change the city landscape as well as generate environmental degradation. This paper looks at the missing link between land use planning and urban growth, and it implications for environmental sustainability in a selected sub Saharan Africa city of Kaduna, Nigeria. We assessed urban growth from historical GIS data of the city to evaluate the urban expansion. At the same time, regression analysis was used to established relationship between carbon emission and traffic volume in the city. A city characterized by weak land use planning has created a gap leading to uncoordinated land use planning and uncontrolled physical growth. A steady increase of built up area of 8,400.31 hectares in 1982 to an area of 17,120.5 hectares in 2015 can be a reflection of the presence of uncontrolled urban expansion. The lack of coordination between land use planning and urban growth has resulted to environmental ills within the city. One among the ills, is ubiquitous traffic congestion within the city leading to high carbon (CO2 emission. Findings shows a strong connection between emission and volume of traffic. In addition to findings, is the decline of green areas in the city. By this findings, it is suggested that the modern concept of land use planning which embraces flexibility, public participation and integration of environmental issues should be entrenched and allow to take the lead in the process of urban growth.

    2015-03-01

    Full Text Available In the current context of economic recovery and rebalancing, the necessity of modelling and estimating the potential output and output gap emerges in order to assess the quality and sustainability of economic growth, the monetary and fiscal policies, as well as the impact of business cycles. Despite the importance of potential GDP and the output gap, there are difficulties in reliably estimating them, as many of the models proposed in the economic literature are calibrated for developed economies and are based on complex macroeconomic relationships and a long history of robust data, while emerging economies exhibit high volatility. The object of this study is to develop a model in order to estimate the potential GDP and output gap and to assess the sustainability of projected growth using a multivariate filter approach. This trend estimation technique is the newest approach proposed by the economic literature and has gained wide acceptance with researchers and practitioners alike, while also being used by the IMF for Romania. The paper will be structured as follows. We first discuss the theoretical background of the model. The second section focuses on an analysis of the Romanian economy for the 1995–2013 time frame, while also providing a forecast for 2014–2017 and an assessment of the sustainability of Romania’s economic growth. The third section sums up the results and concludes.

    Full Text Available Enterprises should find a new business model for their development, so as to make better use of their own advantages. At the same time, with rapid development of the economy and of science technology, the competition between small and medium-sized enterprises (SMEs and large enterprises is inevitable, so it is very important for small and medium-sized enterprises to find better ways to improve their ability to compete. E-commerce is a new medium of commerce in this 21st century, so as to promote the quantity development of SMEs and enhance the risk management ability of enterprises. However, at present, many of China’s small and medium enterprises face many challenges in the process of electronic commerce’s development, such as, which factors hinder the performance of electronic commerce, and what aspect of enterprises should be improved? This paper is based on the above problems, using theoretical analysis and empirical research methods to explore the root of these problems and find the solutions. In the empirical section, we explore how e-commerce influences sales growth in the short- and long-term. Through analysis of e-commerce performance, we further explore the causality relationship and influence degree. The results show that: first, IT Investment is the most important factor to achieve success, what competitive advantage can be achieved largely depends on whether enterprises will effectively use the network technology; second, the expansion of the enterprise size can promote transaction volume increase of SMEs in the short term; third, internet availability has a positive effect on the trade volume of e-commerce, but the intensity is not obvious, and the effect is relatively stable.

    Full Text Available Estimating the sources of economic growth within the framework of the conventional growth accounting approach is based on two assumptions namely the factor markets are competitive and the underlying aggregate production function has a specific form. In this study, following Iwata et al (2003, sources of economic growth and total factor productivity (TFP growth in the Turkish economy for the period 1968-2006 were estimated with nonparametric regression approach which does not require imposing these restrictive assumptions. Nonparametric estimates of income share of capital and labor indicated there are diminishing returns to scale in the Turkish economy. According to results, capital formation is the main sources of growth before in the pre-1980 period, TFP is the sources of growth with the exception of 1991-95 period and post-1980 period seems to be the sources of growth. It is observed that labor’s contribution to economic growth reached the highest level in the 1991-95.

    2015-05-01

    Full Text Available “Incentivized Sustainable Mobility” is a conceptual business model which involves four stakeholders: citizens, municipalities, commerce and mobility services. A platform named “ISUMO” (Incentivized Sustainable Mobility provides technological support to this business model, integrating a set of metaservices that unifies the existing ICTs of transportation plus a unique patented QR-based (Quick Response low-cost charging device for electric vehicles. Essentially, the system tracks and registers citizens’ transportation activities (anonymously and voluntarily and evaluates each through a scoring system while their ecological footprint is calculated. Afterwards, citizens are able to exchange their accumulated points for discount QR coupons, to be redeemed in the associated commerce in order to purchase their products or services. The breakthrough of this business model is that it enhances awareness of sustainable mobility practices, increasing their attractiveness as perceived by the stakeholders with diverse benefits; citizens (and indirectly, the municipalities initiate a new consumption pattern of “coupons culture” linked to sustainable mobility, the urban economy is stimulated, and the use of mobility services grows, providing a new business opportunity regarding electric vehicles. It is expected that continuous exploration of the model and implementation will contribute to sustainable social and economic development aiming at CO2 emissions reduction, headline targets of the Europe 2020 strategy.

    2015-07-01

    Full Text Available A question fundamental to sustainable economic growth is whether a poor region tends to grow faster than a rich one, such that the poor region catches up with the rich region in terms of the level of per capita income. In this article, we apply the spatial panel data approach to the analysis of regional income convergence across 177 economic areas in the contiguous US states over the period from 1969 to 2009. Using data on per capita incomes in the functionally defined economic areas, we find that the absolute value of the estimated coefficient of the initial per capita income decreases in the spatial and time-period fixed effects spatial lag model and increases in the spatial and time-period fixed effects spatial error model. This result implies that the growth rate in a specific economic area will be not only directly affected by an exogenous shock introduced into that economic area but also be impacted more by both the indirect effects of the first-order neighboring economic areas and the induced effects of the higher-order neighboring economic areas. This gives helpful hints on the issue of spatial interaction and regional policy coordination to start a virtuous circle of sustainable economic growth.

    Over the last decade the concept of functional foods and nutraceuticals (FFN) has gained support from various stakeholders including the food industry, scientific and academic community, government institutions or regulators, producers and consumers. However, as one begins to evaluate the global FFN industry, several issues emerge including (i) a lack of consensus across jurisdictions for acknowledging safe and efficacious FFN, (ii) challenges regarding the classification of novel food-derived bioactives as FFN or drugs, and (iii) a disconnect between nutrient requirements and dosages of FFN required to facilitate health benefits. The objectives of the present review are to discuss the role of existing stakeholders within the FFN marketplace and identify performance indicators for growth within the FFN sector. In addition, the following report provides feasible resolutions to present and future challenges facing the global FFN industry to ensure sustained long-term growth.

  14. Landscape urbanization and economic growth in China: positive feedbacks and sustainability dilemmas.

    Accelerating urbanization has been viewed as an important instrument for economic development and reducing regional income disparity in some developing countries, including China. Recent studies (Bloom et al. 2008) indicate that demographic urbanization level has no causal effect on economic growth. However, due to the varying and changing definition of urban population, the use of demographic indicators as a sole representing indicator for urbanization might be misleading. Here, we re-examine the causal relationship between urbanization and economic growth in Chinese cities and provinces in recent decades, using built-up areas as a landscape urbanization indicator. Our analysis shows that (1) larger cities, both in terms of population size and built-up area, and richer cities tend to gain more income, have larger built-up area expansion, and attract more population, than poorer cities or smaller cities; and (2) that there is a long-term bidirectional causality between urban built-up area expansion and GDP per capita at both city and provincial level, and a short-term bidirectional causality at provincial level, revealing a positive feedback between landscape urbanization and urban and regional economic growth in China. Our results suggest that urbanization, if measured by a landscape indicator, does have causal effect on economic growth in China, both within the city and with spillover effect to the region, and that urban land expansion is not only the consequences of economic growth in cities, but also drivers of such growth. The results also suggest that under its current economic growth model, it might be difficult for China to control urban expansion without sacrificing economic growth, and China's policy to stop the loss of agricultural land, for food security, might be challenged by its policy to promote economic growth through urbanization.

    According to United Nation, world population may reach 10.1 billion by the year 2100. The fossil fuel based global economy is not sustainable. For sustainable global green energy scenario we must consider free fuel based energy conversion, environmental concerns and conservation of water. Photovoltaics (PV) offers a unique opportunity to solve the 21st century's electricity generation because solar energy is essentially unlimited and PV systems provide electricity without any undesirable impact on the environment. Innovative paths for green energy conversion and storage are proposed in areas of R and D, manufacturing and system integration, energy policy and financing. With existing silicon PV system manufacturing, the implementation of new innovative energy policies and new innovative business model can provide immediately large capacity of electricity generation to developed, emerging and underdeveloped economies.

    2013-06-01

    This doctoral thesis is based on four peer reviewed articles, which together make a coherent longitudinal research and knowledge creating process, with conceptual integration and dialectical reasoning as its corner stones. The thesis is based on zooming in from large scale thinking - philosophy and worldview - towards smaller scale issues, first in order to understand, then to deepen knowledge through research, then to search for solutions for clearly explicated problems, and finally to implement the findings in practice. The logical framework is as follows: The state of the global environment is approaching a point where the whole of humankind is in danger. These issues are widely discussed and analysed. The change towards more sustainable development will be a long societal process, and it will be essential to understand the characteristics and dialectics of the process. The author presents and analyses his three layer model of societal evolution. The change of making humankind more sustainable creates practical needs - real actions will be necessary - but above all, it creates a need to develop scientific understanding, which is briefly discussed. The production of energy has traditionally been one of the core issues concerning the effect humankind has on the environment, and in the process of change, the potential reform of the energy sector will be in a key position. The main part of the thesis' empirical material concerns the energy sector and its potential shift towards the principle of sustainable energy. (orig.)

    2010-06-01

    Full Text Available Credit growth rates as high as 30% or 50% a year were observed in some Central Eastern European countries (CEECs in 2006-2007, such as the Baltic States, Bulgaria or Romania. This strong credit growth could have been due to the catching-up process but could also have been excessive, paving the way to the credit crunch that followed the crisis in 2008-2009. We try to assess the excessiveness of credit by applying a number of methods. First, we consider the gap between current credit and its long-term trend and we find some signs of credit booms, in several CEECs in 2005-2007. Second, we assess the "normal" growth of credit with regard to fundamentals through econometric estimations. Credit growth is also shown to have been excessive in several countries just before the 2008-2009 financial crisis.

    China's rapid and sustained economic growth offers an opportunity to ask whether the advantages of growth diffuse throughout an economy, or remain localized in areas where the growth has been the greatest. A critical policy area in China has been the health system, and health inequality has become an issue that has led the government to broaden national health insurance programs. This study investigates whether health system resources and performance have converged over the past 30 years across China's 31 provinces. To examine geographic variation of health system resources and performance at the provincial level, we measure the degree of sigma convergence and beta convergence in indicators of health system resources (structure), health services utilization (process), and outcome. All data are from officially published sources: the China Health Statistics Year Book and the China Statistics Year Book. Sigma convergence is found for resource indicators, whereas it is not observed for either process or outcome indicators, indicating that disparities only narrowed in health system resources. Beta convergence is found in most indicators, except for 2 procedure indicators, reflecting that provinces with poorer resources were catching up. Convergence found in this study probably reflects the mixed outcome of government input, and market forces. Thus, left alone, the equitable distribution of health care resources may not occur naturally during a period of economic growth. Governmental and societal efforts are needed to reduce geographic health variation and promote health equity. © The Author(s) 2016.

  3. Is rapid growth in Internet usage environmentally sustainable for Australia? An empirical investigation.

    2016-03-01

    This study estimates the short- and long-run effects of Internet usage and economic growth on carbon dioxide (CO2) emissions using annual time series macro data for Australia for the period 1985-2012. Autoregressive distributive lag (ARDL) bounds and Gregory-Hansen structural break cointegration tests are applied. ARDL estimates indicate no significant long-run relationship between Internet usage and CO2 emissions, which implies that the rapid growth in Internet usage is still not an environmental threat for Australia. The study further indicates that higher level of economic growth is associated with lower level of CO2 emissions; however, Internet usage and economic growth have no significant short-run relationship with CO2 emissions. Financial development has both short-run and long-run significant positive association with CO2 emissions. The findings offer support in favor of energy efficiency gains and a reduction in energy intensity in Australia. However, impulse response and variance decomposition analysis suggest that Internet usage, economic growth and financial development will continue to impact CO2 emissions in the future, and as such, this study recommends that in addition to the existing measures to combat CO2 emissions, Australia needs to exploit the potential of the Internet not only to reduce its own carbon footprint but also to utilize information and communication technology (ICT)-enabled emissions abatement potential to reduce emissions in various other sectors across the economy, such as, power, renewable energy especially in solar and wind energy, agriculture, transport and service.

    Details of a fast and sustainable bottom-up process to grow large area high quality graphene films without the aid of any catalyst are reported in this paper. We used Melaleuca alternifolia, a volatile natural extract from tea tree plant as the precursor. The as-fabricated graphene films yielded a stable contact angle of 135°, indicating their potential application in very high hydrophobic coatings. The electronic devices formed by sandwiching pentacene between graphene and aluminum films demonstrated memristive behavior, and hence, these graphene films could find use in nonvolatile memory devices also.

    This paper introduces convergent innovation (CI) as a form of meta-innovation-an innovation in the way we innovate. CI integrates human and economic development outcomes, through behavioral and ecosystem transformation at scale, for sustainable prosperity and affordable universal health care within a whole-of-society paradigm. To this end, CI combines technological and social innovation (including organizational, social process, financial, and institutional), with a special focus on the most underserved populations. CI takes a modular approach that convenes around roadmaps for real world change-a portfolio of loosely coupled complementary partners from the business community, civil society, and the public sector. Roadmaps serve as collaborative platforms for focused, achievable, and time-bound projects to provide scalable, sustainable, and resilient solutions to complex challenges, with benefits both to participating partners and to society. In this paper, we first briefly review the literature on technological innovation that sets the foundations of CI and motivates its feasibility. We then describe CI, its building blocks, and enabling conditions for deployment and scaling up, illustrating its operational forms through examples of existing CI-sensitive innovation. © 2014 The New York Academy of Sciences.

    Full Text Available In this study we investigated the relation between energy consumption and growth of total factor productivity (TFP of agriculture in Iran from 1974 to 2012 using Solow residual method. The results from estimated aggregate Cobb–Douglas production function showed that one percent change in the value of labor, capital and energy will lead to 4.07, 0.09 and 0.49 percent change in agriculture value added, respectively. Also in a long term, based on the Johansen cointegration test, there is a negative relation between TFP growth and energy consumption in Iranian agriculture which might be due to cheap and inefficient energy use in this sector. Gradual liberalization of energy price and use of so called green box support policies is recommended.

    This study's objective was to determine the effects in dogs of oral capromorelin, a ghrelin agonist, at different doses for 7 days on food consumption, body weight and serum concentrations of growth hormone (GH), insulin-like growth factor 1 (IGF-1), and cortisol. Adult Beagles (n = 6) were dosed with placebo BID, capromorelin at 3.0 mg/kg SID, 4.5 mg/kg SID, or 3.0 mg/kg BID. Food consumption, body weight, serum capromorelin, GH, IGF-1, and cortisol were measured at intervals on days 1, 4, 7, and 9. Capromorelin increased food consumption and body weight compared to placebo and caused increased serum GH, which returned to the baseline by 8 h postdose. The magnitude of the GH increase was less on days 4 and 7 compared to Day 1. IGF-1 concentrations increased on Day 1 in capromorelin-treated dogs and this increase was sustained through Day 7. Serum cortisol increased postdosing and returned to the baseline concentrations by 8 h. The magnitude of the increase was less on days 4 and 7 compared to Day 1. A dose of 3 mg/kg was chosen for further study in dogs based on this dose causing increased food consumption and sustained IGF-1 serum concentrations that may increase lean muscle mass when administered over extended periods. © 2016 The Authors.

  11. Incorporating Role of Stakeholders into Corporate CSR Strategy For Sustainable Growth: An Exploratory Study

    Directory of Open Access Journals (Sweden)

    Tanggamani Vani

    2017-01-01

    Full Text Available In today’s modern day context, Corporate Social Responsibility (CSR become the mantra for businesses as it can be seen as a strategic approach for firms to be succeed in their business endeavours. Hence, it remains the most widely used concept to refer to organizational- stakeholder relationships. An understanding about a stakeholder approach to CSR is an important means for a firm to enhance their commitment to operate in an economically, socially and environmentally sustainable manner. In support with above arguments, this article presents a theoretical proposition based on stakeholder theory for better CSR and firm performance. By drawing upon classic work in the field, the paper offers conceptual discussion and then systematically develops a means of stakeholder approach into corporate CSR strategy. The aim of this paper is to demonstrates the need for a firm to enhance further understanding about the role of stakeholders in the context of corporate CSR strategy, which is increasingly necessary in view of the fact that business entities are absolutely essential for economic development, but at the same time, their business activities pose a huge impact to society and the environment. Thus, firm's CSR disclosure is a pivotal tool to establish a relationship of working together with the stakeholders that ensures mutual benefit and continue to be a firm that is needed by society. This article contributes to the literature by providing a fundamental explanation of how a business should embrace responsibility for the impact of its activities on the stakeholders across various levels of the value chain. By doing so, firms are offered a means to take a much more proactive approach to CSR through the stakeholder approach which is precisely helpful in measuring the effectiveness of any CSR initiative on the society to foster business sustainability.

  12. HOW TO SUSTAIN ECONOMIC PERFORMANCE? ECONOMIC GROWTH AND ITS IMPACT FACTORS

    Directory of Open Access Journals (Sweden)

    2012-05-01

    Full Text Available This paper intends to render several important factors of impact on economic growth and to describe the particular types of relationships of the latter with each one of its influencing elements. In order to correctly determine such issue, we have resorted to three carefully selected models that have been estimated and compared so as to identify the most adequate and representative regression. For this purpose we have performed an analysis based on cross-section annual data for 105 countries spread all over the world. After having tested and rejected certain exogenous variables initially considered, such as imports or exports, we have finally retained the external debt and foreign direct investments as explanatory items of the dependent variable. The results revealed that both of them positively affect the gross domestic product of the analysed countries, this one being inelastic in relation to the exogenous variables considered. Even if the relationship between the economic growth and the external debt of a country is usually negative, as the money exit out of the country due to the debt service causes non-achieved potential investments, yet, there is an inflexion point up to which the external debt has a positive influence on economic growth by the increase of the investments funds acquired as result of the external credit contracting, this being the case reflected by our study. As for the relationship existing between foreign direct investments and GDP, the economic theory confirms that FDI and economic growth are directly correlated, the former contributing to technical progress, production increase and, finally, to the improvement of the living standard.

    While regional countries are driving the global 'green growth' agenda, policymakers are facing a new economic reality and heightened uncertainty. The challenge of eco-efficient economic growth and inclusive resource use is critical and growing in several countries. Fundamental, rather than incremental changes are needed. Governments must therefore take the lead in re-orienting both the 'visible' and the 'invisible' economic infrastructure. At the same time the implications of heightened uncertainty and risk for policymaking requires more attention. This report highlights changes in the policy landscape that have taken place since 2005, focuses on the emerging challenges of resources and resilience, presents new regional and country data produced by the Commonwealth Scientific and Industrial Research Organisation of Australia (CSIRO) and UNEP, and provides insights to key policy arenas for greening of growth. The report is the sixth in a series of reports produced every five years by ESCAP for the Ministerial Conference on Environment and Development. It is also the third in the ADB's Asian Environment Outlook series. This year, it complements a UNEP report: Resource Efficiency: Economics and Outlook for Asia and the Pacific (Canberra, CSIRO Publishing), providing new insights into regional use of key resources, and what that means for economies in the Asia-Pacific Region. The report is also intended to support stakeholders preparing for Rio+20.

    Despite decades of international experience with the use of information and communication technologies in healthcare delivery, widespread telehealth adoption remains limited and progress slow. Escalating health system challenges related to access, cost and quality currently coincide with rapid advancement of affordable and reliable internet based communication technologies creating unprecedented opportunities and incentives for telehealth. In this paper, we will describe how Human Factors Engineering (HFE) and user-centric elements have been incorporated into the establishment of telehealth within a large academic medical center to increase acceptance and sustainability. Through examples and lessons learned we wish to increase awareness of HFE and its importance in the successful implementation, innovation and growth of telehealth programs.

    Grain legumes are a cost-effective alternative for the animal protein in improving the diets of the poor in South-East Asia and Africa. Legumes, through symbiotic nitrogen fixation, meet a major part of their own N demand and partially benefit the following crops of the system by enriching soil. In realization of this sustainability advantage and to promote pulse production, United Nations had declared 2016 as the "International Year of pulses". Grain legumes are frequently subjected to both abiotic and biotic stresses resulting in severe yield losses. Global yields of legumes have been stagnant for the past five decades in spite of adopting various conventional and molecular breeding approaches. Furthermore, the increasing costs and negative effects of pesticides and fertilizers for crop production necessitate the use of biological options of crop production and protection. The use of plant growth-promoting (PGP) bacteria for improving soil and plant health has become one of the attractive strategies for developing sustainable agricultural systems due to their eco-friendliness, low production cost and minimizing consumption of non-renewable resources. This review emphasizes on how the PGP actinobacteria and their metabolites can be used effectively in enhancing the yield and controlling the pests and pathogens of grain legumes.

  16. Global health and development: conceptualizing health between economic growth and environmental sustainability.

    Science.gov (United States)

    Borowy, Iris

    2013-07-01

    After World War II, health was firmly integrated into the discourse about national development. Transition theories portrayed health improvements as part of an overall development pattern based on economic growth as modeled by the recent history of industrialization in high-income countries. In the 1970s, an increasing awareness of the environmental degradation caused by industrialization challenged the conventional model of development. Gradually, it became clear that health improvements depended on poverty-reduction strategies including industrialization. Industrialization, in turn, risked aggravating environmental degradation with its negative effects on public health. Thus, public health in low-income countries threatened to suffer from lack of economic development as well as from the results of global economic development. Similarly, demands of developing countries risked being trapped between calls for global wealth redistribution, a political impossibility, and calls for unrestricted material development, which, in a world of finite land, water, air, energy, and resources, increasingly looked like a physical impossibility, too. Various international bodies, including the WHO, the Brundtland Commission, and the World Bank, tried to capture the problem and solution strategies in development theories. Broadly conceived, two models have emerged: a "localist model," which analyzes national health data and advocates growth policies with a strong focus on poverty reduction, and a "globalist" model, based on global health data, which calls for growth optimization, rather than maximization. Both models have focused on different types of health burdens and have received support from different institutions. In a nutshell, the health discourse epitomized a larger controversy regarding competing visions of development.

    Full Text Available The paper assessed agricultural production systems from a sustainability perspective defined in terms of relatively homogeneous agro-ecological zones of Africa, using the framework of a production function. Data used were drawn from FAOSTAT, the National Centre for Atmospheric Research and World Bank Indicators respectively for the period 1961-2009. The data were separated into three sub periods, namely: entire period (1961-2009, the pre-Structural Adjustment Period (SAP reform period (1961-1985 and the post SAP reform period (1986-2009. This was necessitated by the need to examine whether production systems may have been shifted out of the overall trajectory of system evolution by shocks e.g. policy (SAP among others. To investigate whether there has been a degradation of the quality of the natural resource base across the diverse agro-ecological zones; the estimated TFP trends were related to changes in selected resource quality variables over time. The results showed that the Northern and Southern agro-ecological zones had non-negative trends in TFP, indicating sustainability of production systems. However, the result indicated that the policy instrument (structural adjustment programme may have shifted farming or production systems out of the overall trajectory of system evolution in three out of the five agro-ecological zones studied which showed negative TFP trends. A degradation of resource quality over time was noted during the pre-SAP reform period, but was maintained during the post-SAP period.

    Full Text Available The paper presents the concept of Fair Trade, which is considered an alternative to conventional trade, and becomes increasingly popular in the Western countries. In addition, some results of empirical research, conveyed in Poland and aimed at diagnosis and assessment of Fairtrade products market, are provided. Fair trade is analysed not only in the broad theoretical context which shows its contribution to sustainable development and relation to corporate social responsibility, but also in the framework of supply chains management. The benefits from the Fairtrade label, including transaction costs reduction are indicated. The assumption is that to achieve them, consumer acceptance of the idea and willingness to buy Fairtrade products are necessary. The empirical research was focused on answering the question whether a market niche for Fairtrade goods exists in Poland and how to develop it by the means of communication tools. The market niche, although very small, has been identified and described. It is apparent that, in order to develop it, a public policy, aimed at raising the awareness of Fair Trade idea, is necessary as well as marketing activities like social marketing Internet campaigns and better and more prominently products display.

    This study provides the first evidence that treatment of human pancreatic adenocarcinoma is markedly improved by the intratumoral administration of chemotherapeutic agents in a novel drug delivery system. The effect of chemotherapeutic agents delivered in a sustained-release, protein-based, injectable gel was evaluated on the growth of human pancreatic adenocarcinoma cell line, BxPC-3. In vitro chemosensitivity of BxPC-3 cells exposed for 24 or 72 h to fluorouracil (0.01-5 mM), cisplatin or doxorubicin (0.1-50 microM) and floxuridine, vinblastine, mitomycin or paclitaxel (1.0-100 microM) was compared with that of untreated cells. In vitro chemosensitivity was also studied with fluorouracil and mitomycin in the poorly differentiated PANC-1, human pancreatic cancer cell line. Survival was determined after 7-10 days. All drugs decreased cell growth in a dose-dependent fashion. The efficacy of fluorouracil, cisplatin and doxorubicin increased with prolonged exposure, rendering these drugs most appropriate for a sustained-release preparation. For in vivo studies, athymic nude mice bearing BxPC-3 xenografts were treated either with fluorouracil, cisplatin or doxorubicin in the therapeutic injectable gel containing epinephrine or with vehicle alone administered intratumorally on days 1 and 4. After 28 days, the mice were sacrificed and tumors dissected and weighed. Tumors in mice treated with the injectable gel decreased in size by 72-79% compared with tumors in untreated controls and tumors treated with vehicle alone. Intratumoral injection of drug solution and intraperitoneal injection of drug in the injectable gel did not change tumor size compared with controls. In a drug-retention study, mice were injected intratumorally with [3H]fluorouracil either in the injectable gel or in solution. Sustained radioactivity was observed in tumors injected with the gel, and, conversely, greater radioactivity was detected in the liver and kidneys in mice receiving the radiolabeled

    Full Text Available Although China has promoted the construction of Chinese Sustainable Ground Transportation (CSGT to guide sustainable development, it may create substantial challenges, such as rapid urban growth and land limitations. This research assessed the effects of the Hangzhou Bay Bridge on impervious surface growth in Cixi County, Ningbo, Zhejiang Province, China. Changes in impervious surfaces were mapped based on Landsat images from 1995, 2002, and 2009 using a combination of multiple endmember spectral mixture analysis (MESMA and landscape metrics. The results indicated that the area and density of impervious surfaces increased significantly during construction of the Hangzhou Bay Bridge (2002–2009. Additionally, the bridge and connected road networks promoted urban development along major roads, resulting in compact growth patterns of impervious surfaces in urbanized regions. Moreover, the Hangzhou Bay Bridge promoted the expansion and densification of impervious surfaces in Hangzhou Bay District, which surrounds the bridge. The bridge also accelerated socioeconomic growth in the area, promoting rapid urban growth in Cixi County between 2002 and 2009. Overall, the Hangzhou Bay Bridge is an important driver of urban growth in Cixi County, and policy suggestions for sustainable urban growth should be adopted in the future.

    Full Text Available The article considers the issue of dependence of key macroeconomic indicators on the energy supply price dynamics, especially oil price, relevant to the modern Russian economy. In order to overcome the negative trends related to oil price dynamics, the authors propose to consider the measures on the gradual diversification of the Russian economy as an effective tool of state regulation. To test the hypothesis that diversification contributes to the increase in sustainability of the national economic system, the authors review the simultaneous equations model, the endogenous variables of which include structural values which reflect the structure of national production system. The share of gross value added (hereinafter, GVA generated in the i-th sector in the total GVA and the base GVA index generated in the i-th sector similar to the industry output index sequentially serve as endogenous variables in this study. The test of the hypothesis was carried out in two stages: at the first stage, according to the results of econometric modeling, the indicator of the real effective ruble exchange rate to foreign currencies was chosen as the main exogenous variable; at the second stage, the basic system of equations was evaluated. Econometric calculations have been made for the following types of economic activity (according to the classification of the\tRussian National Classifier of Economic Activities: agriculture, hunting and forestry; mineral extraction; manufacturing; wholesale and retail trade; repairs of motor vehicles, motorcycles, household goods and personal appliances. During the econometric modeling, co-integrated equations for the pairs of indicators under study have been obtained; it has also been concluded that there are significant disparities in the selected economic sectors. The analysis of the obtained data has helped develop a set of measures of state regulation aimed at overcoming the existing disparities

    The topic of trade effects on economic growth has been usually controversial. Former empirical evidence linking trade to growth in Israel has been mixed and inconclusive either. This study reexamines the role of trade in Israel by testing for cointegration and causality from both exports and imports to output and total factor productivity over the period 1960-2004. The results suggest that both output and TFP are positively long-run correlated with exports and imports. The Granger causality t...

    The light reactions in photosynthesis drive both linear and cyclic electron transport around photosystem I (PSI). Linear electron transport generates both ATP and NADPH, whereas PSI cyclic electron transport produces ATP without producing NADPH. PSI cyclic electron transport is thought to be essential for balancing the ATP/NADPH production ratio and for protecting both photosystems from damage caused by stromal overreduction. Two distinct pathways of cyclic electron transport have been proposed in angiosperms: a major pathway that depends on the PROTON GRADIENT REGULATION 5 (PGR5) and PGR5-LIKE PHOTOSYNTHETIC PHENOTYPE 1 (PGRL1) proteins, which are the target site of antimycin A, and a minor pathway mediated by the chloroplast NADH dehydrogenase-like (NDH) complex. Recently, the regulation of PSI cyclic electron transport has been recognized as essential for photosynthesis and plant growth. In this review, we summarize the possible functions and importance of the two pathways of PSI cyclic electron transport.

    The vulnerability to medical emergencies is greatest in space where there are real limits to the availability or effectiveness of ground based assistance. Moreover, astronaut safety and health maintenance will be of increasing importance as we venture out into space for extended periods of time. It is therefore critical to understand the mechanisms of the regulatory physiology of homeostatic systems (sleep, circadian, neuroendocrine, fluid and nutritional balance) and the key roles played in adaptation. This synergy project has combined aims of the "Human Performance Factors, Sleep and Chronobiology Team"; the "Immunology, Infection and Hematology Team"; and the "Muscle Alterations and Atrophy Team", to broadly address the effects of long term sleep reduction, as is frequently encountered in space exploration, on neuroendocrine, neuroimmune and circulating growth factors. Astronaut sleep is frequently curtailed to averages of between 4- 6.5 hours per night. There is evidence that this amount of sleep is inadequate for maintaining optimal daytime functioning. However, there is a lack of information concerning the effects of chronic sleep restriction, or reduction, on regulatory physiology in general, and there have been no controlled studies of the cumulative effects of chronic sleep reduction on neuroendocrine and neuroimmune parameters. This synergy project represents a pilot study designed to characterize the effects of chronic partial sleep deprivation (PSD) on neuroendocrine, neuroimmune and growth factors. This project draws its subjects from two (of 18) conditions of the larger NSBRI project, "Countermeasures to Neurobehavioral Deficits from Cumulative Partial Sleep Deprivation During Space Flight", one of the projects on the "Human Performance Factors, Sleep and Chronobiology Team ". For the purposes of this study, to investigate the effects of chronic sleep loss on neuroendocrine and neuroimmune function, we have focused on the two extreme sleep conditions

    Mineralization of (14)C-labeled tracers is a common way of studying the environmental fate of xenobiotics, but it can be difficult to extract relevant kinetic parameters from such experiments since complex kinetic functions or several kinetic functions may be needed to adequately describe large data sets. In this study, we suggest using a two-parameter, sigmoid Gompertz function for parametrizing mineralization curves. The function was applied to a data set of 252 normalized mineralization curves that represented the potential for degradation of the herbicide MCPA in three horizons of an agricultural soil. The Gompertz function fitted most of the normalized curves, and trends in the data set could be visualized by a scatter plot of the two Gompertz parameters (rate constant and time delay). For agricultural topsoil, we also tested the effect of the MCPA concentration on the mineralization kinetics. Reduced initial concentrations lead to shortened lag-phases, probably due to reduced need for bacterial growth. The effect of substrate concentration could be predicted by simply changing the time delay of the Gompertz curves. This delay could to some extent also simulate concentration effects for 2,4-D mineralization in agricultural soil and aquifer sediment and 2,6-dichlorobenzamide mineralization in single-species, mineral medium.

    The rate of evolutionary adaptation in long-lived organisms such as forest trees cannot compete with the current and predicted rate of climate change. Tree growth and survival under warming and drying climate, such as predicted for the Mediterranean and other regions, will depend therefore on the existing plasticity of physiological and phenological traits. We examined seven physiological and phenological parameters in Pinus halepensis, a drought resistant Mediterranean tree species, using five ecotypes growing under meso-Mediterranean (MM), thermo-Mediterranean (TM), and semi-arid (SA) climates. The results revealed that both phenotypic plasticity and locally adapted ecotypes contributed, differentially, to the success of this species across a wide range of climatic conditions. While some ecotypes had an inherent xylem resistance to embolism (percent loss of conductivity halepensis performs well under drought conditions it has a sensitive hydraulic system. This was reflected in 50% loss of hydraulic conductivity at relatively high leaf water potential of -3.1 MPa. This, however, was compensated for by a narrow safety margin allowing leaf gas exchange up to leaf water potential of -2.8 MPa. The hydraulic sensitivity also requires fast cavitation reversal, which was indeed observed in the dry season on hourly time-scale: Two cycles of cavitation and reversal observed during morning and afternoon, which were also reflected in a decoupling between sap flow and leaf transpiration. The results indicate newly observed hydraulic capabilities of trees that together with plasticity of other traits facilitate the adjustment to increasingly dry conditions, and the potential of P. halepensis to maintain its current geographical distribution even in face of predicted warming and drying trends.

    Developing low-cost, scalable and reproducible synthesis methods for water oxidation reaction (WOR) catalysts is highly desirable and also challenging in energy, environmental and industrial applications. In this context, electrochemical deposition is known as an easy and cost-effective technique in nanomaterial growth. Herein, cobalt-based nanoflakes were grown on a flexible and commercially available steel mesh substrate by electrodeposition approach with a crystalline structure as a mixture of oxide, hydroxide and oxyhydroxide phases. For the first time, the correlation between electrodeposition parameters, time and current density, and morphological characteristics of the grown nanoflakes (density and aspect ratio based on SEM results) has been derived. According to a comprehensive study of the flakes’ electrocatalytic performance in WOR, the optimized sample fabricated with a moderate electrodeposition current density (7 mA cm‑2) and duration time (2000 s) revealed the highest density (7.6  ×  108 cm‑2) and aspect ratio (7.1) as well as the lowest values for overpotential (OP  =  324 mV) and charge transfer resistance (14 Ω). This designed array of Co-based nanoflakes also showed the lowest value of overpotential for bare cobalt-based WOR electrocatalysts reported yet. High and low values for deposition current density and/or deposition time had a negative effect on the sample surface, leaving some areas without any flakes or with incomplete and inefficient formation of nanoflakes with low densities and aspect ratios. A similar effect was observed for annealed samples in the range of 200–400 °C. Based on recorded overpotentials and extracted surface morphological parameters, a linear and logarithmic behavior in overpotential–flake density dependency was proposed for current density and time controlled systems, respectively.

    Full Text Available The presentations of primary and metastatic cutaneous malignant melanoma (CMM are very diverse. Evidence increasingly indicates that single CMM cells spread to distant sites quite early during cancer progression and are soon eliminated before they become clinically detectable. However bulky metastases which appear at a later stage might derive from some of these early neoplastic cells. It seems that local CMM single cell micro-metastases commonly predict sentinel lymph node involvement without overtly reflecting CMM progression to bulky visceral metastases. This study is intended to review the current understanding of the mechanisms underlying two CMM presentations. The first is the long interval, apparently disease-free, with persistent CMM dormancy, which may precede overt metastatic growth. Immunosurveillance may induce dormancy in single CMM cells disseminated in the body by blocking their proliferation cycle. The second is the socalled CMM smoldering phenomenon, which is marked by an alternate progression and regression of CMM locally with metastases that wax and wane for long periods of time over restricted skin areas. These very diverse patterns of CMM progression are likely to be ascribable to a number of biological factors, including the activation of CMM stem cells, and the combined phenotypic heterogeneity and variability in proliferative amplification in CMM cell clusters. Furthermore an adequate stimulation of CMM immune-surveillance and the induction of a specific stromal structure and vascular response are required. In this context, most early CMM tumors are in part controlled by lymphocytemediated responses before they become clinically detectable. However both the role of immune-surveillance and the mechanisms underlying both persistent and smoldering CMM dormancy remain unclear.

    The publication of the Brundtland Report in 1987 put the topic of sustainable development on the political and corporate agenda. Defining sustainable development as “a development that meets the needs of the future without compromising the ability of future generations to meet their own needs......” (WCED, 1987, p. 43), the Report also put a positive spin on the issue of sustainability by upholding capitalist beliefs in the possibility of infinite growth in a world of finite resources. While growth has delivered benefits, however, it has done so unequally and unsustainably. This thesis focuses...... on the textile and fashion industry, one of the world’s most polluting industries and an industry to some degree notorious for leading the ‘race to the bottom’ in global labour standards. Despite being faced with increasing demands to practise sustainability, most textile and fashion companies continue to fail...

    Full Text Available The present study illustrates a multidimensional analysis of an indicator of urban land use efficiency (per-capita built-up area, LUE in mainland Attica, a Mediterranean urban region, along different expansion waves (1960–2010: compaction and densification in the 1960s, dispersed growth along the coasts and on Athens’ fringe in the 1970s, fringe consolidation in the 1980s, moderate re-polarization and discontinuous expansion in the 1990s and sprawl in remote areas in the 2000s. The non-linear trend in LUE (a continuous increase up to the 1980s and a moderate decrease in 1990 and 2000 preceding the rise observed over the last decade reflects Athens’ expansion waves. A total of 23 indicators were collected by decade for each municipality of the study area with the aim of identifying the drivers of land use efficiency. In 1960, municipalities with low efficiency in the use of land were concentrated on both coastal areas and Athens’ fringe, while in 2010, the lowest efficiency rate was observed in the most remote, rural areas. Typical urban functions (e.g., mixed land uses, multiple-use buildings, vertical profile are the variables most associated with high efficiency in the use of land. Policies for sustainable land management should consider local and regional factors shaping land use efficiency promoting self-contained expansion and more tightly protecting rural and remote land from dispersed urbanization. LUE is a promising indicator reflecting the increased complexity of growth patterns and may anticipate future urban trends.

    Interactions between butterflies and caterpillars in the genus Pieris and plants in the family Brassicaceae are among the best explored in the field of insect-plant biology. However, we report here for the first time that Pieris brassicae, commonly assumed to be a typical folivore, actually prefers to feed on flowers of three Brassica nigra genotypes rather than on their leaves. First- and second-instar caterpillars were observed to feed primarily on leaves, whereas late second and early third instars migrated via the small leaves of the flower branches to the flower buds and flowers. Once flower feeding began, no further leaf feeding was observed. We investigated growth rates of caterpillars having access exclusively to either leaves of flowering plants or flowers. In addition, we analyzed glucosinolate concentrations in leaves and flowers. Late-second- and early-third-instar P. brassicae caterpillars moved upward into the inflorescences of B. nigra and fed on buds and flowers until the end of the final (fifth) instar, after which they entered into the wandering stage, leaving the plant in search of a pupation site. Flower feeding sustained a significantly higher growth rate than leaf feeding. Flowers contained levels of glucosinolates up to five times higher than those of leaves. Five glucosinolates were identified: the aliphatic sinigrin, the aromatic phenylethylglucosinolate, and three indole glucosinolates: glucobrassicin, 4-methoxyglucobrassicin, and 4-hydroxyglucobrassicin. Tissue type and genotype were the most important factors affecting levels of identified glucosinolates. Sinigrin was by far the most abundant compound in all three genotypes. Sinigrin, 4-hydroxyglucobrassicin, and phenylethylglucosinolate were present at significantly higher levels in flowers than in leaves. In response to caterpillar feeding, sinigrin levels in both leaves and flowers were significantly higher than in undamaged plants, whereas 4-hydroxyglucobrassicin leaf levels were

    2012-04-01

    Full Text Available The Whistler Aerosol and Cloud Study (WACS 2010, included intensive measurements of trace gases and particles at two sites on Whistler Mountain. Between 6–11 July 2010 there was a sustained high-pressure system over the region with cloud-free conditions and the highest temperatures of the study. During this period, the organic aerosol concentrations rose from <1 μg m−3 to ∼6 μg m−3. Precursor gas and aerosol composition measurements show that these organics were almost entirely of secondary biogenic nature. Throughout 6–11 July, the anthropogenic influence was minimal with sulfate concentrations <0.2 μg m−3 and SO2 mixing ratios ≈ 0.05–0.1 ppbv. Thus, this case provides excellent conditions to probe the role of biogenic secondary organic aerosol in aerosol microphysics. Although SO2 mixing ratios were relatively low, box-model simulations show that nucleation and growth may be modeled accurately if Jnuc = 3 × 10−7[H2SO4] and the organics are treated as effectively non-volatile. Due to the low condensation sink and the fast condensation rate of organics, the nucleated particles grew rapidly (2–5 nm h−1 with a 10–25% probability of growing to CCN sizes (100 nm in the first two days as opposed to being scavenged by coagulation with larger particles. The nucleated particles were observed to grow to ∼200 nm after three days. Comparisons of size-distribution with CCN data show that particle hygroscopicity (κ was ∼0.1 for particles larger 150 nm, but for smaller particles near 100 nm the κ value decreased near midway through the period from 0.17 to less than 0.06. In this environment of little anthropogenic influence and low SO2, the rapid growth rates of the regionally nucleated particles – due to condensation of biogenic SOA – results in an unusually high efficiency of conversion of

    As a form of therapeutic angiogenesis, we sought to investigate the safety and efficacy of a sustained-release system of basic fibroblast growth factor (bFGF) using biodegradable gelatin hydrogel in patients with critical limb ischemia (CLI). We conducted a phase I-IIa study that analyzed 10 CLI patients following a 200-μg intramuscular injection of bFGF-incorporated gelatin hydrogel microspheres into the ischemic limb. Primary endpoints were safety and transcutaneous oxygen pressure (TcO2) at 4 and 24 weeks after treatment. During the follow-up, there was no death or serious procedure-related adverse event. After 24 weeks, TcO2 (28.4 ± 8.4 vs. 46.2 ± 13.0 mmHg for pretreatment vs after 24 weeks, p < 0.01) showed significant improvement. Regarding secondary endpoints, the distance walked in 6 min (255 ± 105 vs. 318 ± 127 m, p = 0.02), the Rutherford classification (4.4 ± 0.5 vs. 3.1 ± 1.4, p = 0.02), the rest pain scale (1.7 ± 1.0 vs. 1.2 ± 1.3, p = 0.03), and the cyanotic scale (2.0 ± 1.1 vs. 0.9 ± 0.9, p < 0.01) also showed improvement. The blood levels of bFGF were within the normal range in all patients. A subanalysis of patients with arteriosclerosis obliterans (n = 7) or thromboangiitis obliterans (Buerger's disease) (n = 3) revealed that TcO2 had significantly improved in both subgroups. TcO2 did not differ between patients with or without chronic kidney disease. The sustained release of bFGF from biodegradable gelatin hydrogel may offer a safe and effective form of angiogenesis for patients with CLI.

    Climate change is real. And it's happening much faster than was predicted just a few years ago. The good news is that there is a good chance that we really can do something about the problem. And this is in a way where we don't need to compromise the well-being of our global economy. All it takes is to follow a Bright Green strategy where we get the most out of the energy we produce and where we deploy the clean energy technologies we already know can work. Doing so would deliver the affordability, stability and confidence our economies need, as well as help solve the climate crisis. Although our reliance on fossil fuels has created global warming, we now have the opportunity and obligation to begin a transformation towards a robust clean energy economy. This is the opportunity of our generation. To begin a transformation to an economy that is robust without causing environmental harm. But there won't be a single, 'silver bullet' solution. We will need to address energy production, carbon mitigation and efficient consumption of energy. A new approach is needed that both avoids dangerous climate change and is advantageous for the economy - a Bright Green strategy with a strong focus on deploying and investing in climate friendly technologies. Denmark has done this for several decades and we are a clear example that it is possible to both grow our economy and at the same time take care of the environment and especially the global environment. This book tells the Bright Green story of Denmark, and presents a wide range of technologies and solutions that can help pave the way towards a more climate friendly future. (au)

    Dehalococcoides ethenogenes strain 195 (DE195) was grown in a sustainable syntrophic association with Desulfovibrio vulgaris Hildenborough (DVH) as a co-culture, as well as with DVH and the hydrogenotrophic methanogen Methanobacterium congolense (MC) as a tri-culture using lactate as the sole energy and carbon source. In the co- and tri-cultures, maximum dechlorination rates of DE195 were enhanced by approximately three times (11.0±0.01 lmol per day for the co-culture and 10.1±0.3 lmol per day for the tri-culture) compared with DE195 grown alone (3.8±0.1 lmol per day). Cell yield of DE195 was enhanced in the co-culture (9.0±0.5 x 107 cells per lmol Cl{sup -} released, compared with 6.8±0.9x 107 cells per lmol Cl{sup -} released for the pure culture), whereas no further enhancement was observed in the tri-culture (7.3±1.8x 107 cells per lmol Cl{sup -} released). The transcriptome of DE195 grown in the co-culture was analyzed using a whole-genome microarray targeting DE195, which detected 102 significantly up- or down-regulated genes compared with DE195 grown in isolation, whereas no significant transcriptomic difference was observed between co- and tri-cultures. Proteomic analysis showed that 120 proteins were differentially expressed in the co-culture compared with DE195 grown in isolation. Physiological, transcriptomic and proteomic results indicate that the robust growth of DE195 in co- and tri-cultures is because of the advantages associated with the capabilities of DVH to ferment lactate to provide H2 and acetate for growth, along with potential benefits from proton translocation, cobalamin-salvaging and amino acid biosynthesis, whereas MC in the tri-culture provided no significant additional benefits beyond those of DVH.

    Full Text Available When the global community entered in the XXI century world emerging economy is more clearly considered as post-industrial, where a leading sector of the economy in the GDP production is not agriculture and not even industry but services. The main productive resource in such circumstances is not natural and productive capital but human capital, which is represented by storage of knowledge and skills accumulated by a person in the process of training and previous employment. Value of this capital is directly dependent on the level of education both general and professional. Human intellect becomes a main factor of production and professional. If the level is higher it means that such person can perform more valuable types of work for expand wealth of the country and it is transformed into intellectual capital. Consequently, a special market is formed that is a market of intellectual capital. An offer in this market is represented by labor with a high level of intellectuality and innovativeness and it has, in its turn, high market value. Well-handled components of human capital contribute to scientific-technical and social progress of the society, its sustainable economic development as the main types of final products unlike with previous stages of development are information and knowledge and the main factor of economic growth is productivity of mental labor workers. It is human capital that is one of the main factors ensuring transition to V and VI technological paradigms under current conditions. These paradigms are underlying a solid foundation for formation of new intellectual and information society. New knowledge and information technologies are making a breakthrough not only in the direct production of commodities but in the non-manufacturing sector as well (education, health, trade, finance etc..

    Full Text Available The objective of this paper is to present the results of an analysis of the indicator Greenhouse gas emissions (GGE. The GGE is one of the headline indicators tracked under the EU’s main socioeconomic strategy until the year 2020 – the EUROPE 2020 strategy for smart, sustainable and inclusive growth. In the area of sustainable growth, the Resource-efficient Europe initiative was established. For 2020, the EU has made a unilateral commitment to reduce overall greenhouse gas emissions from its 28 member states by 20 % compared to 1990 levels. The GGE indicator shows total man-made emissions of the so-called Kyoto basket of greenhouse gases. It presents annual total emissions in relation to those observed in 1990. The aggregate greenhouse gas emissions are expressed in units of CO2 equivalent. The development of the GGE indicator in the EU and in the Czech Republic from 2000 to 2014 from the point of view of the ability to achieve the Strategy objectives is analyzed. In terms of the level of the analyzed indicator, the set of the EU countries can be divided into two significantly different groups – the euro area and the non-euro area; or into groups by the year of their joining the EU. Analyses of the dependency between the growth of GGE and the GDP growth for both the set of the 28 EU countries and the Czech Republic are presented as well.

    Full Text Available European cities and regions are facing the crucial challenge of greening their economy towards more sustainable patterns. Politicians and policy-makers should promote new policies for sustainable growth including renewables, greenhouse gas emissions, energy efficiency and biodiversity. All of these aspects can be considered as a boost for local and regional economy. In this regard, European countries and regions can benefit from the Europe 2020 Strategy which is defined as Europe’s blueprint for a smart, sustainable and inclusive future, providing a ten year roadmap for growth and jobs. EU2020S was designed as a European exit strategy from the global economic and financial crisis in view of new European economic governance. This study discusses the above issues regarding Italy and intends to provide some answers on the perspectives of the new EU2020S. It draws from a research project supported by ESPON, the S.I.E.S.T.A. Project, focused on the territorial dimension of the EU2020S. Therefore, this paper aims at analyzing Italian regional patterns on climate change, green economy and energy within the context of EU2020S and at providing policy recommendations for better achieving the goals of the Strategy.

    Full Text Available This study aims to investigate the characteristics of the efficient evolution of China’s iron and steel industry against the backdrop of limited openness and regulation and to discuss the important effects of regulatory policy and total factor productivity (TFP of China’s iron and steel industry. The method adopted the Cobb–Douglas production function combined with a semi-parametric method to decompose productivity. This study based on the micro-level dataset of iron and steel enterprises in the database of China’s industrial enterprises between 1998 and 2007 that investigated the intrinsic correlation among corporate entry and exit, market competition of existing enterprises, and TFP growth in the iron and steel industry. The results of the research show that the entry-exit would promote the growth of the aggregate productivity, while the low efficiency of resource allocation would significantly inhibit the TFP growth. The basic conclusion is that, with substantial government intervention in enterprise investments, market competition may not promote optimal resource allocation efficiency in China’s iron and steel industry, but make the allocation less efficient.

    Macroscopic evidence of contracture has been identified as a major issue during the regeneration process. We hypothesize that lack of angiogenesis is the primary cause of contracture and explore a nanomedicine approach to achieve sustained release of vascular endothelial growth factor (VEGF) to stimulate angiogenesis. We evaluate the efficacy of poly(lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) for long-term (3 months) sustained release of VEGF in bladder acellular matrix allografts (BAMA) in a swine model. We anticipate that the sustained release of VEGF could stimulate angiogenesis along the regeneration process and thereby inhibit contracture. Bladder was replaced with BAMA (5×5 cm), modified with PLGA NPs encapsulated with VEGF in a pig model. The time points chosen for sampling were 1, 2, 4, and 12 weeks. The regenerated areas were then measured to obtain the contracture rate, and the extent of revascularization was calculated using histological and morphological features. In the control group of animals, the bladder was replaced with only BAMA. The in vivo release of VEGF was evident for ∼3 months, achieving the goal of long-acting sustained release, and successfully promoted the regeneration of blood vessels and smooth muscle fibers. In addition, less collagen deposition was observed in the experimental group compared with control. Most importantly, the inhibition of contracture was highly significant, and the ultimate contracture rate decreased by ∼57% in the experimental group compared with control. In isolated strips analysis, there were no significant differences between BAMA-regenerated (either VEGF added or not) and autogenous bladder. BAMA modified with VEGF-loaded PLGA-NPs can sustainably release VEGF in vivo (>3 months) to stimulate angiogenesis leading to the inhibition of contracture. This is the first study to report a viable nanomedicine-based strategy to overcome contracture during bladder regeneration induced by BAMA. Furthermore

    Full Text Available Anaemia in school aged girls is an important but neglected issue. Since iron supplementation programmes have had little reported success in reducing anaemia, interest is turning to food based approaches that have higher potential for achieving far reaching benefits. The purpose of the study was to observe sustainability of the effect of iron and food supplementation on haemoglobin (Hb, intelligence quotient (IQ and growth of the subjects. At baseline, estimation of haemoglobin (Hb, red cell indices, serum iron, total iron binding capacity, serum transferrin saturation and serum ferritin was done. IQ, weight and height were measured using standard procedures. Anaemic subjectswere divided into three groups, viz., (i twice weekly supplementation of iron folic acid syrup (53 mg iron/week; (ii daily supplementation of 4 niger seed and defatted soyaflour biscuits plus 2 lemons (45 mg iron/week and (iii control. Non anaemic group(NAC was not intervened. Endline data was collected after 120 days. Follow up for Hb, IQ, weight and height was done 4 months after cessation of supplementation. The prevalence of anaemia was 77% in the study population; 46% subjects had mild anaemia and 32% had moderate anaemia. Iron status was lower in anaemic subjects (p<0.001.Iron supplementation was more effective in raising Hb and building iron stores than iron rich food supplementation. Iron supplementation improved IQ but did not bring about catch up of anaemics to non anaemics. Iron rich food supplementation was better than medicinal iron in promoting growth in anaemic girls. The impact of iron rich food supplementation on Hb, IQ and growth sustained for 4 months while that of medicinal iron did not. Effects of food supplementation are sustainable for 4 months, therefore, this strategy holds more potential to control anaemia, in school aged girls.

    Planning is an integral element of good management and necessary to anticipate events not merely respond to them. Projecting the quantity and spatial distribution of urban growth is essential to effectively plan for the delivery of city services and to evaluate potential environmental impacts. The major drivers of growth in large urban areas are increasing population, employment opportunities, and quality of life attractors such as a favorable climate and recreation opportunities. The spatial distribution of urban growth is dictated by the amount and location of developable land, topography, energy and water resources, transportation network, climate change, and the existing land use configuration. The Atlanta region is growing very rapidly both in population and the consumption of forestland or low-density residential development. Air pollution and water availability are significant ongoing environmental issues. The Prescott Spatial Growth Model (SGM) was used to make growth projections for the metropolitan Atlanta region to 2010,2020 and 2030 and results used for environmental assessment in both business as usual and smart growth scenarios. The Prescott SGM is a tool that uses an ESRI ArcView extension and can be applied at the parcel level or more coarse spatial scales and can accommodate a wide range of user inputs to develop any number of growth rules each of which can be weighted depending on growth assumptions. These projections were used in conjunction with meteorological and air quality models to evaluate future environmental impacts. This presentation will focus on the application of the SGM to the 13-County Atlanta Regional Commission planning jurisdiction as a case study. The SGM will be described, including how rule sets are developed and the decision process for allocation of future development to available land use categories. Data inputs required to effectively run the model will be discussed. Spatial growth projections for ten, twenty, and thirty

    Full Text Available Turkey held the presidency of the G20 (Group of 20 from December 2014 to November 2015. During this period geopolitical tensions started to spread beyond the borders of the regions involved. Turkey went through a challenging time, with a slowing economy, two elections in 2015, revived political confrontations, two million refugees and frustrations in securing its borders and handling terrorism. Turkey defined three priorities for its presidency: inclusiveness, implementation and investment for growth. To combat inequality and ensure inclusive growth, it aimed to address the issues of small and medium-sized enterprises, such as access to finance, skills and global value chains, employment for youth and women, and support to the development of low-income countries. Inclusiveness was also explicit in G20 engagement with social partners. Implementation was emphasized, particularly related to the imperative to deliver on the G20 members’ commitments regarding growth strategies made at the 2014 Brisbane Summit. This article assesses the G20’s performance under the Turkey presidency within a functional paradigm focusing on the three main objectives of plurilateral summitry institutions: strengthening capacity for political leadership to launch new ideas and overcome deadlocks, reconciling domestic and international pressures, and consolidating collective management. To attain those objectives, institutions are expected to demonstrate leadership, solidarity, sustainability, acceptability, consistency and continuity. Efficiency is perceived as G20 performance on a combination of the criteria. Given the G20’s ultimate mission to achieve strong, sustainable, balanced and inclusive growth, all the issues on Turkey’s G20 agenda were grouped according to these four growth pillars. G20 performance on each of the issue areas was assessed on six criteria using a three-point scale: high (1, medium (0 and low (−1 degree of performance. The overall

    DEFF Research Database (Denmark)

    van Gemert, Rob; Andersen, Ken Haste

    2018-01-01

    Currently applied fisheries models and stock assessments rely on the assumption that density-dependent regulation only affects processes early in life, as described by stock–recruitment relationships. However, many fish stocks also experience density-dependent processes late in life......, such as density-dependent adult growth. Theoretical studies have found that, for stocks which experience strong late-in-life density dependence, maximum sustainable yield (MSY) is obtained with a small fishery size-at-entry that also targets juveniles. This goes against common fisheries advice, which dictates...... that primarily adults should be fished. This study aims to examine whether the strength of density-dependent growth in actual fish stocks is sufficiently strong to reduce optimal fishery size-at-entry to below size-at-maturity. A size-structured model is fitted to three stocks that have shown indications of late-in-life...

    Full Text Available This study examined changes in agricultural productivity in Sub-Sahara Africa countries in the context of diverse institutional arrangements using Data Envelopment Analysis (DEA. From a time series which consists of information on agricultural production and means of production were obtained from FAO AGROSTAT and rainfall data from Steve O’Connell data base. The information was for a 43-year period (1961-2003; DEA method was used to measure Malmquist index of total factor productivity. A decomposition of TFP measures revealed that the observed increase in the TFP in the sub–Sahara Africa agriculture is due to technological change rather than efficiency change which is the main constrained of achieving higher level of TFP during the reference period. The study further examined the effect of land quality, malaria, education and selected governance indicators such as, control of corruption and government effectiveness on productivity growth. All the variables included in the model are significant with the exception of government effectiveness

Under microaerobic conditions, growth came to a gradual halt, although more than 60% of the glucose was still left. A decline in growth was not observed during microaerobic cultivation when acetate was added to the medium.......

    Activation of endogenous cardiac stem/progenitor cells (eCSCs) can improve cardiac repair after acute myocardial infarction. We studied whether the in situ activation of eCSCs by insulin-like growth factor 1 (IGF-1) and hepatocyte growth factor (HGF) could be increased using a newly developed hydrogel in chronic myocardial infarction (MI). One-month post-MI pigs underwent NOGA-guided intramyocardial injections of IGF-1/HGF (GF: both 0.5 μg/mL, n = 5) or IGF-1/HGF incorporated in UPy hydrogel (UPy-GF; both 0.5 μg/mL, n = 5). UPy hydrogel without added growth factors was administered to four control (CTRL) pigs. Left ventricular ejection fraction was increased in the UPy-GF and GF animals compared to CTRLs. UPy-GF delivery reduced pathological hypertrophy, led to the formation of new, small cardiomyocytes, and increased capillarization. The eCSC population was increased almost fourfold in the border zone of the UPy-GF-treated hearts compared to CTRL hearts. These results show that IGF-1/HGF therapy led to an improved cardiac function in chronic MI and that effect size could be further increased by using UPy hydrogel.

    Gómez-López, María D; del Amor, Francisco M

    2013-03-30

    The use of organic cultivation with manures does not avoid the risk of high nitrate concentrations if nutrient management is inefficient. So we studied the influence of three organic manures combined or not with additional chemical fertilisers on growth and yield of sweet pepper (Capsicum annuum L.), and on the soil and plant N concentrations. After 3 years of organic cultivation, poultry manure caused the highest soil pollution. The evolution of nitrate and organic matter in soil showed a pattern close to that of plant growth. The addition of mineral fertiliser increased vegetative growth and yield, and a cumulative season effect was observed. In treatments with no additional mineral fertiliser N translocation from leaves to fruits happened. A cumulative effect of seasons on fruit quality and a reduction near to 30% was observed in the first fruit quality category after 3 years. The fruit vitamin C content was reduced by increasing N fertilisation. The effects of organic fertiliser on soil and plant growth and yield depended on the type of manure used, its rate, and consecutive crop seasons. Horse manure gave the best combination of agricultural and environmental characteristics and could be used without additional fertigation. © 2012 Society of Chemical Industry.

    Full Text Available Private sustainability standards are increasingly important in food trade with developing countries, but the implications for smallholder farmers are still poorly understood. We analyze the implications of different coffee certification schemes in Ethiopia using cross-sectional survey data, and regression and propensity-score-matching techniques. We find that: Rainforest Alliance (RA and double Fairtrade-Organic (FT-Org certifications are associated with higher incomes and reduced poverty, mainly because of higher prices; Fairtrade (FT certification hardly affects welfare; and Organic (Org certification reduces incomes, chiefly due to lower yields. Cooperative heterogeneity importantly shapes these results. Results imply that private standards may not always deliver what they promise to consumers.

    2015-07-01

    Full Text Available In this research paper, the main theoretical arguments for discussions are as following: female labour force participation in transition countries, female employment in economic sectors and their main barriers, and the contributions of female labour force in economic growth. In methodology, the secondary data are used, and they are calculated through STATA program. The main analysis include: descriptive statistic, regression analysis and correlation matrix. Based on empirical results, the regression analysis has found that economic growth and government effectiveness has a negative impact on female labour force. Financial market development, enterprises reforms, and innovation have a positive impact on female labour force in SEE (South Eastern European countries. In T-statistic analysis all independent variables have shown a negative significance (T <2 on female labour force. In correlation, economic growth and financial development market have negative correlation on female labour force, but other variables have shown positive correlation. SEE countries should develop the female labour force in their economies, so their role may be crucial toward different economic problems and challenges in the modern economy.

    Full Text Available Many countries, particularly those in the developing world, are under increasing pressure to improve their growth rates in order to tackle pressing economic problems at the domestic level. Increasing export volumes can make a positive contribution to a country’s economic growth rate, but it can also endanger the environment. How to reconcile the often conflicting phenomena of increased export activity, stronger economic growth and a lower carbon footprint is the focus of this study. A core outcome of the study was the creation of a single list using a cross-section of international sources, of low-carbon environmental goods, and their ranking according to their inherent ability to reduce greenhouse gas emissions, South Africa’s capacity to produce them, and their economic benefits, as reflected in the export opportunities they present. These export opportunities were revealed through the application of the Decision Support Model (DSM, an export market selection tool that incorporates a systematic filtering and screening system. The results of the analysis should help guide policymakers in their strategic deliberations on which export sectors to incentivise and support with a view to encouraging more ‘green’ growth in South Africa in the years ahead. diffusion of such goods. If the production and export of environmental goods were to increase, it could have a potentially positive effect on economic and environmental objectives, such as raising economic growth rates and lowering greenhouse gas intensity, respectively.

    Full Text Available We study how the information and communications technology (ICT ecosystem affects the sustainable growth of ICT firms. For our study, we analyze the efficiencies of ICT firms in China, South Korea, the United States, and Japan, which are the current leaders in the global ICT industry, each with different ICT ecosystem structures. We use metafrontier analysis (MFA to compare the efficiencies among countries with different structures, and then use Tobit regression to identify the causes of the efficiency gaps. Our results reveal that the US has the highest efficiency, followed by Japan, South Korea, and China, in that order, and the countries with more balanced ICT ecosystems across sub-industries—manufacturing, software and IT services, content, and telecommunications—have more efficient ICT industries. This suggests that a more balanced industrial development is important to enhancing the overall competitiveness of the ICT industry.

  10. Extracellular Matrix (ECM Multilayer Membrane as a Sustained Releasing Growth Factor Delivery System for rhTGF-β3 in Articular Cartilage Repair.

    Directory of Open Access Journals (Sweden)

    Soon Sim Yang

    Full Text Available Recombinant human transforming growth factor beta-3 (rhTGF-β3 is a key regulator of chondrogenesis in stem cells and cartilage formation. We have developed a novel drug delivery system that continuously releases rhTGF-β3 using a multilayered extracellular matrix (ECM membrane. We hypothesize that the sustained release of rhTGF-β3 could activate stem cells and result in enhanced repair of cartilage defects. The properties and efficacy of the ECM multilayer-based delivery system (EMLDS are investigated using rhTGF-β3 as a candidate drug. The bioactivity of the released rhTGF-ß3 was evaluated through chondrogenic differentiation of mesenchymal stem cells (MSCs using western blot and circular dichroism (CD analyses in vitro. The cartilage reparability was evaluated through implanting EMLDS with endogenous and exogenous MSC in both in vivo and ex vivo models, respectively. In the results, the sustained release of rhTGF-ß3 was clearly observed over a prolonged period of time in vitro and the released rhTGF-β3 maintained its structural stability and biological activity. Successful cartilage repair was also demonstrated when rabbit MSCs were treated with rhTGF-β3-loaded EMLDS ((+ rhTGF-β3 EMLDS in an in vivo model and when rabbit chondrocytes and MSCs were treated in ex vivo models. Therefore, the multilayer ECM membrane could be a useful drug delivery system for cartilage repair.

    Since medical insurance was introduced in the Republic of Korea, there have been several increases concerning medical waste. In order to solve these problems, we have applied life cycle assessment and life cycle cost. But these methods cannot be a perfect decision-making tool because they can only evaluate environmental and economic burdens. Thus, as one of many practical methods the shared smart and mutual - green growth considers economic growth, environmental protection, social justice, science technology and art, and mutual voluntarism when applied to medical waste management in the Republic of Korea. Four systems were considered: incineration, incineration with heat recovery, steam sterilisation, and microwave disinfection. This research study aimed to assess pollutant emissions from treatment, transport, and disposal. Global warming potential, photochemical oxidant creation potential, acidifications potential, and human toxicity are considered to be environmental impacts. Total investment cost, transport cost, operation, and maintenance cost for the medical waste are considered in the economy evaluations though life cycle cost. The social development, science technology and art, and mutual voluntarism are analysed through the Delphi-method conducted by expert groups related to medical waste. The result is that incineration with heat recovery is the best solution. However, when heat recovery is impossible, incineration without heat recovery becomes the next best choice. That is why 95% of medical waste is currently treated by both incineration and incineration with heat recovery within the Republic of Korea. © The Author(s) 2015.

    The number of patients suffering from postoperative pain due to orthopedic surgery and bone fracture is projected to dramatically increase because the human life span, weight, and involvement in high-activity sports continue to rise worldwide. Joint replacement or bone fracture frequently results in skeletal pain that needs to be adequately controlled for the patient to fully participate in needed physical rehabilitation. Currently, the 2 major therapies used to control skeletal pain are nonsteroidal anti-inflammatory drugs and opiates, both of which have significant unwanted side effects. To assess the efficacy of novel therapies, mouse models of orthopedic and fracture pain were developed and evaluated here. These models, orthopedic surgery pain and bone fracture pain, resulted in skeletal pain-related behaviors that lasted 3 weeks and 8 to 10 weeks, respectively. These skeletal pain behaviors included spontaneous and palpation-induced nocifensive behaviors, dynamic weight bearing, limb use, and voluntary mechanical loading of the injured hind limb. Administration of anti-nerve growth factor before orthopedic surgery or after bone fracture attenuated skeletal pain behaviors by 40% to 70% depending on the end point being assessed. These data suggest that nerve growth factor is involved in driving pain due to orthopedic surgery or bone fracture. These animal models may be useful in developing an understanding of the mechanisms that drive postoperative orthopedic and bone fracture pain and the development of novel therapies to treat these skeletal pains.

    Basic fibroblast growth factor (bFGF) has an established pivotal function in biomedical engineering, especially for the human pluripotent stem cells (iPSCs). However, the limitation of bFGF is the ease of denaturation under normal physiological conditions, inducing loss of its activity. In this study, we designed multi-trilayered nanofilm composed of a repeating polycation/polyanion/bFGF structure, which has high loading efficiency and short buildup time. We also investigated that the loading and release of bFGF from the nanofilm with two parameters (counter-polyanion and film architectures). Then, we prepared the optimized nanofilm which maintains a sustained bFGF level in physiological condition to apply the nanofilm to human iPSCs culture. The amount of bFGF release from 12 trilayer nanofilm was 36.4 ng/cm(2), and activity of bFGF encapsulated into the nanofilm was maintained (60%) until 72 h during incubation at 37 °C. As a result, the iPSCs grown in the presence of the nanofilm with tridaily replacement of growth medium maintained undifferentiated morphology and expression levels of pluripotency marker proteins.

    Eukaryotic development and stem cell control depend on the integration of cell positional sensing with cell cycle control and cell wall positioning, yet few factors that directly link these events are known. The DEFECTIVE KERNEL1 (DEK1) gene encoding the unique plant calpain protein is fundamental for development and growth, being essential to confer and maintain epidermal cell identity that allows development beyond the globular embryo stage. We show that DEK1 expression is highest in the actively dividing cells of seeds, meristems and vasculature. We further show that eliminating Arabidopsis DEK1 function leads to changes in developmental cues from the first zygotic division onward, altered microtubule patterns and misshapen cells, resulting in early embryo abortion. Expression of the embryonic marker genes WOX2, ATML1, PIN4, WUS and STM, related to axis organization, cell identity and meristem functions, is also altered in dek1 embryos. By monitoring cell layer-specific DEK1 down-regulation, we show that L1- and 35S-induced down-regulation mainly affects stem cell functions, causing severe shoot apical meristem phenotypes. These results are consistent with a requirement for DEK1 to direct layer-specific cellular activities and set downstream developmental cues. Our data suggest that DEK1 may anchor cell wall positions and control cell division and differentiation, thereby balancing the plant's requirement to maintain totipotent stem cell reservoirs while simultaneously directing growth and organ formation. A role for DEK1 in regulating microtubule-orchestrated cell wall orientation during cell division can explain its effects on embryonic development, and suggests a more general function for calpains in microtubule organization in eukaryotic cells. © The Author 2015.

  17. Nuclear Symbiosis - A Means to Achieve Sustainable Nuclear Growth while Limiting the Spread of Sensititive Nuclear Technology

    Energy Technology Data Exchange (ETDEWEB)

    2009-09-01

    Global growth of nuclear energy in the 21st century is creating new challenges to limit the spread of nuclear technology without hindering adoption in countries now considering nuclear power. Independent nuclear states desire autonomy over energy choices and seek energy independence. However, this independence comes with high costs for development of new indigenous fuel cycle capabilities. Nuclear supplier states and expert groups have proposed fuel supply assurance mechanisms such as fuel take-back services, international enrichment services and fuel banks in exchange for recipient state concessions on the development of sensitive technologies. Nuclear states are slow to accept any concessions to their rights under the Non-Proliferation Treaty. To date, decisions not to develop indigenous fuel cycle capabilities have been driven primarily by economics. However, additional incentives may be required to offset a nuclear state’s perceived loss of energy independence. This paper proposes alternative economic development incentives that could help countries decide to forgo development of sensitive nuclear technologies. The incentives are created through a nuclear-centered industrial complex with “symbiotic” links to indigenous economic opportunities. This paper also describes a practical tool called the “Nuclear Materials Exchange” for identifying these opportunities.

    Alignment is the degree to which component parts of academic health centers (AHCs) work cohesively. Full alignment allows AHCs to act quickly and cohesively toward common goals and to take advantage of opportunities that present themselves, particularly where collaboration is essential. Maryland's two major AHCs-University of Maryland Medicine (UMM) and Johns Hopkins Medicine (JHM)-have experienced periods of significant misalignment during each of their histories. Their most recent periods of misalignment caused significant negative economic and academic impacts. However, the process of realigning their clinical and research missions has not only given them a renewed economic vigor but has also paid significant dividends for the state of Maryland, helping it weather the current recession much better than other regions of the country. The two AHCs' continued economic success during the recession has led Maryland lawmakers to increasingly seek out their expertise in attempts to stimulate economic development. Indeed, UMM, JHM, and other fully aligned AHCs have shown that they can be powerful economic engines and offer a model of job growth and economic development in the 21st century.

    Herein, we studied whether sustained exercise positively affects growth of gilthead sea bream by alterations in a) plasma concentrations of insulin and IGF-I, b) signaling pathways in muscle, or c) regulation of lipid metabolism. Specifically, we evaluated the effects of moderated swimming (1.5 body lengths per second; BL/s) on the circulating concentrations of insulin and IGF-I, morphometric parameters, and expression of genes related to lipid metabolism in gilthead sea bream (80-90 g BW). Exercise increased the specific growth rate (P growth and metabolic homeostasis during swimming. The observed decrease in plasma insulin concentrations (P = 0.016) could favor the mobilization of tissue reserves in exercised fish. In this sense, the increase in liver fatty acid content (P = 0.041) and the changes in expression of peroxisome proliferator-activated receptors PPARα (P = 0.017) and PPARγ (P = 0.033) indicated a hepatic lipid mobilization. Concentration of glycogen in both white and red muscles was decreased (P = 0.021 and P = 0.017, respectively) in exercised (n = 12) relative to control (n = 12) gilthead sea bream, whereas concentrations of glucose (P = 0.016) and lactate (P = 0.0007) were decreased only in red muscle, indicating the use of these substrates. No changes in the glucose transporter and in lipoprotein lipase mRNA expression were found in any of the tissues studied. Exercised sea bream had decreased content of PPARβ mRNA in white and red muscle relative to control sea bream expression (P = 0.001 and P = 0.049, respectively). Mitogen-activated protein kinase phosphorylation was significantly down-regulated in both white and red muscles of exercised sea bream (P = 0.0374 and P = 0.0371, respectively). Tumor necrosis factor-α expression of white muscle was down-regulated in exercised gilthead sea bream (P = 0.045). Collectively, these results contribute to the knowledge base about hormonal regulation of growth and lipid metabolism in exercised gilthead

    Full Text Available This paper carries out a growth accounting exercise for the 10 Central and Eastern European (CEE countries that are part of the European Union over the period 1993-2008. We estimate the capital share (α from a Cobb-Douglas production function in an intensive form, by employing panel data techniques. The Hausman and Chi-Square tests indicate that a Cross- Section Random Effects with Period Fixed Effects model best suits our data. Based on this model, we find a capital share between 0.45 and 0.83, higher than the usual 0.3-0.4 used in growth accounting literature. When we take into consideration the quality of labour force the estimated capital share slightly decreases, but still remains high, in a range between 0.39 and 0.79. Our growth accounting results reveal that, on average, capital per worker accumulation is the main engine of growth in CEE, followed by the contribution of total factor productivity (TFP. However, when dividing by sub-periods, we found that the contribution of TFP cannot be neglected since during 1997-2004 it proved to be the main engine of growth in some CEE countries (Czech Republic, Slovakia, Hungary, Lithuania and Romania. Some policy implications are offered based on our results.

    To investigate the effects of a sustained-released mixture of vascular endothelial growth factor 165 (VEGF165) and fibrin glue (FG) local administration on postoperative rabbit ileal anastomoses. One hundred twenty-eight male and female New Zealand white rabbits underwent intraperitoneal infection subsequent ileal anastomosis surgery were divided randomly into 4 groups, including 32 animals in each, applied with saline solution, FG, rhVEGF165 and a mixture of rhVEGF165 with FG (VEGF + FG) on the anastomoses, respectively. The incidences of anastomotic leakage were observed. Histopathological examination for inflammatory infiltration, fibroblast proliferation, and capillary vascular proliferation were performed. Then, bursting pressure and hydroxyproline concentrations were assessed in anastomoses sits on postoperative days 3, 5, 7, and 14. Rabbits in VEGF + FG group had the lowest incidence of leakage (P < 0.05). Histological evaluations revealed that granulation tissue was formed on days 5 after anastomosis; fibroblast proliferation and capillary vascular proliferation were significantly increased on days 7 and 14 in VEGF + FG group. Furthermore, there was a statistically significant difference in the mean bursting pressures between VEGF + FG group and other groups on days 7 and 14 (P < 0.05), and rabbits in VEGF + FG group exhibited a higher concentration than VEGF group (P < 0.05) and FG group (P < 0.05) on day 14. Administration of VEGF165 mixed with FG to ileal anastomosis accelerates wound healing and enhances the anastomosis by increased angiogenesis.

    The reduction in the under-5 year mortality rate to at least as low as 25 per 1000 livebirths by 2030 has been implemented as one of the new Sustainable Development Goals. Fetal growth restriction (FGR) is one of the most important determinants of infant mortality in developing countries. In this review, we assess the extent of the literature and summarize its findings on the main preventable factors of FGR in Africa. A scoping review was conducted using the Arksey and O'Malley framework. Five bibliographic databases and grey literature were used to identify studies assessing at least one risk factor for FGR. Aggregate risk estimates for the main factors associated with FGR were calculated. Forty-five of a total of 671 articles were selected for the review. The prevalence of FGR varied between 2.6 and 59.2% according to both the African region and the definition of FGR. The main preventable factors reported were a low maternal nutritional status (aggrerate odds ratio [OR]: 2.28, 95% confidence interval [CI] 1.59, 3.25), HIV infection (aOR 1.86, 95% CI 1.38, 2.50), malaria (aOR 1.95, 95% CI 1.04, 3.66), and gestational hypertension (aOR 2.61, 95% CI 2.42, 2.82). FGR is, to a large extent, preventable through existing efficacious interventions dedicated to malaria, HIV and nutrition. Further studies are still needed to assess the influence of risk factors most commonly documented in high-income countries. Improving research on FGR in Africa requires a consensual and standardized definition of FGR-for a higher comparability-between studies and settings. © 2017 John Wiley & Sons Ltd.

  6. Inward foreign direct investment and industrial restructuring: micro evidence – the Slovenian firms’ growth model

    Full Text Available We examine the impact of inward foreign direct investment (FDI on the growth of local firms in terms of employment and total factor productivity (TFP for the Slovenian manufacturing sector in the 1994-2003 period. The theoretically predicted channels through which inward FDI affects the firm dynamics in a host country prove to be in general significant. First, there is evidence of the direct impact offoreign firms through so-called direct technology transfer as foreign-owned firms have higher growth of TFP compared to domestically-owned firms after controlling for other determinants. Secondly, the entry of foreign firms stimulates the reshuffling of the resources from less to more efficient local firms. The firm selection process is, namely, characterised by the least efficient firms experiencing a drop in their employment growth upon a foreign firm’s entry. Thirdly, regarding the productivity spillover effects from foreign to local firms we provide indirect evidence that they mostly operate through vertical linkages rather than within the same industry.In general, it seems that not all firms are equally able to benefit from foreign firms’ presence and that absorptive capacity plays an important role.

    The objective of this work was to assign systematically the normal modes of vibration of the phosphorous(V) oxyfluorates. These compounds are derived from the orthophosphates by successive substitution according to the sequence PO 3-4→PO 3F 2-→PO 2F 2-→POF 3 after consideration of PO 2F 2- (D.F.P.), the work was extended to PO 3F 2- (M.F.P.) and phosphoryl trifluoride (T.F.P.). The a priori calculation of the vibrational frequencies of these species in a local symmetry force field yields very good agreement with the observed frequencies. Furthermore, the results of this vibrational study confirm the contracting effect of the fluorine atoms, which has already been shown by X-ray crystallography.

  8. Adult growth hormone deficiency treatment with a combination of growth hormone and insulin-like growth factor-1 resulting in elevated sustainable insulin-like growth factor-1 and insulin-like growth factor binding protein 3 plasma levels: a case report

    Directory of Open Access Journals (Sweden)

    2010-09-01

    Full Text Available Abstract Introduction Adult Growth hormone Deficiency is a well known phenomenon effecting both males and females. Adult Growth Hormone Deficiency is marked by a number of neuropsychiatric, cognitive performance, cardiac, metabolic, muscular, and bone symptoms and clinical features. There is no known standardized acceptable therapeutic modality to treat this condition. A recent meta-analysis found that after 16 years of Growth Hormone replacement therapy a large proportion of the patients still had Growth Hormone associated symptoms especially related to executive functioning. A major goal is to increase plasma levels of both insulin-like growth factor (insulin-like growth factor-1 and insulin-like growth factor binding protein 3. Case Presentation We report a case of a 45-year-old caucasian woman with early ovarian failure for 2 years and amenorrhea since the age of 43, who presented with Adult Growth Hormone Deficiency and an IGF-1 of 126 ng/mL. Since her insulin-like growth factor-1 was lowest at 81 ng/mL, she was started on insulin-like growth factor-1 Increlex at 0.2 mg at bedtime, which immediately raised her insulin-like growth factor-1 levels to 130 ng/mL within 1 month, and 193 ng/mL, 249 ng/mL, and 357 ng/mL, after 3, 4, and 5 months, respectively, thereafter. Her insulin-like growth factor binding protein 3 continued to decrease. It was at this point when we added back the Growth Hormone and increased her Increlex dosage to 1.3 - 1.5 mg that her insulin-like growth factor binding protein 3 began to increase. Conclusion It appears that in some patients with Adult Growth Hormone Deficiency, insulin-like growth factor-1 elevation is resistant to direct Growth Hormone treatment. Furthermore, the binding protein may not rise with insulin-like growth factor-1. However, a combination of Growth Hormone and insulin-like growth factor-1 treatment may be a solution.

    Acute muscle wasting in the critically ill is common and causes significant morbidity. In a novel human model of acute muscle wasting following cardiac surgery, known or potential circulating modulators of muscle mass--insulin-like growth factor-1, myostatin, and growth and differentiation factor-15--were measured over a week. It was hypothesized that patients who developed acute muscle wasting would show distinct patterns of change in these mediators. A prospective longitudinal observational study of high-risk elective cardiac surgical patients identifying, by ultrasound, those developing muscle wasting. Tertiary cardiothoracic referral center: Royal Brompton Hospital, London, UK. Forty-two patients undergoing elective high-risk cardiothoracic surgery. Circulating insulin-like growth factor-1, myostatin, and growth and differentiation factor-15 were assayed preoperatively and over the first week postoperatively. The ability of growth and differentiation factor-15 to cause muscle wasting in vitro was determined in C2C12 myotubes. Of the 42 patients, 23 (55%) developed quadriceps atrophy. There was an acute decrease in insulin-like growth factor-1 and unexpectedly myostatin, known mediators of muscle hypertrophy and atrophy, respectively. By contrast, plasma growth and differentiation factor-15 concentrations increased in all patients. This increase in growth and differentiation factor-15 was sustained at day 7 in those who developed muscle wasting (day 7 compared with baseline, p0.05). Insulin-like growth factor-1 did not recover in those who developed muscle wasting (day 7 compared with baseline, p0.05). Finally, we demonstrated that growth and differentiation factor-15 caused atrophy of myotubes in vitro. These data support the hypothesis that acute muscle loss occurs as a result of an imbalance between drivers of muscle atrophy and hypertrophy. Growth and differentiation factor-15 is a potential novel factor associated with muscle atrophy, which may become a

    Full Text Available This paper describes one of the major challenges of the future: the sustainable development of the society. Sustainability is now increasingly recognized as central to the growth of emerging market economies. For the banking sector, this represents both a demand for greater social and environmental responsibility as well as a new landscape of business opportunity. Several years ago, the main part of the banks did not consider the social and environmental problems relevant for their operations. Recently, the banks began to realize the major impact of the sustainable development over the way of ulterior development of the society and, implicitly over the way of creating of the banking value in the future. In this context, the development of a banking management system, based on sustainable principles represents one of the provocations of these days.Starting from literature in the sustainable banking management field in this paper are presented several relevant issues related to risk management in the context of sustainable banking financing: the need to implement the sustainable management principles in financial and banking industry; the role of banks in sustainable development of society; social and environmental risk management policies, events that have shaped the role of the banking sector in sustainable development; international standards regarding sustainable banking management such us: Equator Principles for sustainable investment projects’ financing or GRI principles for sustainable reporting. Furthermore, we developed a practical case study related to the implementation of sustainable banking management at Bank of America.

    The discipline of sustainability science has emerged in response to concerns of natural and social scientists, policymakers, and lay people about whether the Earth can continue to support human population growth and economic prosperity. Yet, sustainability science has developed largely independently from and with little reference to key ecological principles that govern life on Earth. A macroecological perspective highlights three principles that should be integral to sustainability science: 1) physical conservation laws govern the flows of energy and materials between human systems and the environment, 2) smaller systems are connected by these flows to larger systems in which they are embedded, and 3) global constraints ultimately limit flows at smaller scales. Over the past few decades, decreasing per capita rates of consumption of petroleum, phosphate, agricultural land, fresh water, fish, and wood indicate that the growing human population has surpassed the capacity of the Earth to supply enough of these essential resources to sustain even the current population and level of socioeconomic development.

    2007-01-01

    Full Text Available This paper discusses possible contributions of psychologists to sustainable transportation. It is argued that in order to reach sustainable transportation, among others, behaviour changes of individual car users are needed. As transport policies will be more effective if they target important antecedents of travel behaviour, first, factors influencing such behaviour are discussed. It is argued that car use is very attractive and sometimes even necessary for many different reasons. This implies that a combination of policies is called for, each targeting different factors that support car use and hinder the use of more sustainable modes of transport. Next, the paper elaborates on policy strategies that may be employed to achieve sustainable transportation by changing car use. Increasing the attractiveness of sustainable transport modes by means of pull measures seems not sufficient to reduce the level of car use. Besides, car use should be made less attractive by means of push measures to force drivers to reconsider their travel behaviour. The acceptability of such policies may be increased by clearly communicating the aim of these policies, and the expected positive consequences (e.g., less congestion, improved environmental quality. Moreover, possible negative effects for individual freedom may be compensated by implementing additional policies aimed at facilitating the use of sustainable transport modes.

    Full Text Available The modern economic system of any nation is divided into three major producer’s sectors called primary, secondary, and tertiary. These sectors reform a chain of production as a continuum, ultimately in the end provide goods and services. In UAE, economy share divided by each sector of the current GDP in year 2015 were 1%, 48%, and 51%, for the primary, secondary, and tertiary sectors, respectively. The purpose of this empirical study is to analyze the economic industries of the secondary sector by projecting the contribution growth share of factors of production through using the growth accounting model for time series from 1990-2015. The methodology employed a quantitative description and data sourced from FCSA. We find the manufacturing industry the main key contributor to sector growth share, followed by the construction industry, where the mining and quarrying subsectors have less impact compared to the rest. We observed that the TFP performance improved positively in line with a declining size of labor.

    2014-01-01

    The willingness of public authority to delegate social and environmental regulation to the private sector has varied from sector to sector, but has often led to the establishment of ‘voluntary’ standards and certifications on sustainability. Many of these have taken the form of ‘stewardship...... councils’ and ‘sustainability roundtables’ and have been designed around a set of institutional features seeking to establish legitimacy, fend off possible criticism, and ‘sell’ certifications to potential users. The concept of ‘roundtabling’ emphasizes the fitting a variety of commodity......-specific sustainability situations into a form that not only ‘hears more voices’ (as in ‘multi-stakeholder’), but also portrays to give them equal standing at the table of negotiations (roundtable), thus raising higher expectations on accountability, transparency and inclusiveness. In this article, I examine to what...

    The long-term substitution of fossil resources can only be achieved through a bio-based economy, with biorefineries and bio-based products playing a major role. However, it is important to assess the implications of the transition to a bio-based economy. Life cycle-based sustainability assessment is probably the most suitable approach to quantify impacts and to identify trade-offs at multiple levels. The extended utilisation of biomass can cause land use change and affect food security of the most vulnerable people throughout the world. Although this is mainly a political issue and governments should be responsible, the responsibility is shifted to companies producing biofuels and other bio-based products. Organic wastes and lignocellulosic biomass are considered to be the preferred feedstock for the production of bio-based products. However, it is unlikely that a bio-based economy can rely only on organic wastes and lignocellulosic biomass.It is crucial to identify potential problems related to socio-economic and environmental issues. Currently there are many approaches to the sustainability of bio-based products, both quantitative and qualitative. However, results of different calculation methods are not necessarily comparable and can cause confusion among decision-makers, stakeholders and the public.Hence, a harmonised, globally agreed approach would be the best solution to secure sustainable biomass/biofuels/bio-based chemicals production and trade, and to avoid indirect effects (e.g. indirect land use change). However, there is still a long way to go.Generally, the selection of suitable indicators that serve the purpose of sustainability assessment is very context-specific. Therefore, it is recommended to use a flexible and modular approach that can be adapted to various purposes. A conceptual model for the selection of sustainability indicators is provided that facilitates identifying suitable sustainability indicators based on relevance and significance in a

    ELABELA (ELA) is a peptide hormone required for heart development that signals via the Apelin Receptor (APLNR, APJ). ELA is also abundantly secreted by human embryonic stem cells (hESCs), which do not express APLNR. Here we show that ELA signals in a paracrine fashion in hESCs to maintain self-renewal. ELA inhibition by CRISPR/Cas9-mediated deletion, shRNA, or neutralizing antibodies causes reduced hESC growth, cell death, and loss of pluripotency. Global phosphoproteomic and transcriptomic analyses of ELA-pulsed hESCs show that it activates PI3K/AKT/mTORC1 signaling required for cell survival. ELA promotes hESC cell-cycle progression and protein translation and blocks stress-induced apoptosis. INSULIN and ELA have partially overlapping functions in hESC medium, but only ELA can potentiate the TGFβ pathway to prime hESCs toward the endoderm lineage. We propose that ELA, acting through an alternate cell-surface receptor, is an endogenous secreted growth factor in human embryos and hESCs that promotes growth and pluripotency.

  6. Towards sustainable development

    Science.gov (United States)

    Munn, R. E.

    Sustainable development is a difficult phrase to define, particularly in the context of human ecosystems. Questions have to be asked, such as "Sustainable for whom?" "Sustainable for what purposes?" "Sustainable at the subsistence or at the luxury level?" and "Sustainable under what conditions?" In this paper, development is taken to mean improving the quality of life. (If development were to mean growth, then it could not be sustained over the long term.) Studies of development must, of course, consider economic factors, particularly in the case of societies who suffer from the pollution of poverty. However, cultural and environmental factors are equally important. In fact, development is not sustainable over the long term if it is not ecologically sustainable. The terms maximum sustainable yield of a renewable resource, carrying capacity of a region and assimilative capacity of a watershed or airshed are discussed. Approaches using these resource management tools are recommended when external conditions are not changing very much. The problem today is that unprecedented rates of change are expected in the next century, not only of environmental conditions such as climate but also of socioeconomic conditions such as renewable resource consumption and populations (of both people and of automobiles)! In rapidly changing situations, policies must be adopted that strengthen resilence and ecosystem integrity; that is, society must increase its ability to adapt. Maintaining the status quo is a long-term prescription for disaster. The problem is of course that little is known about how to design strategies that will increase resilience and ecosystem integrity, and this area of research needs to be strengthened. Some suggestions on appropriate indicators of ecosystem integrity are given in the paper but these need considerable refinement. One of the main problems with long-term environmental policy formulation is the uncertainty to be expected, including the possibility

    Robinett, Rush D. III (.; ); Wilson, David Gerald; Reed, Alfred W.

    2006-05-01

    Exergy is the elixir of life. Exergy is that portion of energy available to do work. Elixir is defined as a substance held capable of prolonging life indefinitely, which implies sustainability of life. In terms of mathematics and engineering, exergy sustainability is defined as the continuous compensation of irreversible entropy production in an open system with an impedance and capacity-matched persistent exergy source. Irreversible and nonequilibrium thermodynamic concepts are combined with self-organizing systems theories as well as nonlinear control and stability analyses to explain this definition. In particular, this paper provides a missing link in the analysis of self-organizing systems: a tie between irreversible thermodynamics and Hamiltonian systems. As a result of this work, the concept of ''on the edge of chaos'' is formulated as a set of necessary and sufficient conditions for stability and performance of sustainable systems. This interplay between exergy rate and irreversible entropy production rate can be described as Yin and Yang control: the dialectic synthesis of opposing power flows. In addition, exergy is shown to be a fundamental driver and necessary input for sustainable systems, since exergy input in the form of power is a single point of failure for self-organizing, adaptable systems.

    2007-03-01

    A bioactive fibrin-based delivery system was used to provide sustained administration of platelet-derived growth factor (PDGF-BB) in a clinically relevant model of intrasynovial flexor tendon repair. We hypothesized that PDGF-BB administered in this manner would improve the sutured tendon's functional and structural properties 3 weeks after repair. A delivery system consisting of 30 microL of fibrin matrix, peptide, heparin, and 100 ng of PDGF-BB was incorporated into the repair sites of randomly selected medial or lateral forepaw flexor digitorum profundus tendons of 8 adult mongrel dogs. The remaining forepaw flexor digitorum profundus tendons were repaired without the growth-factor and fibrin-based delivery system and served as controls. The surgically treated forelimbs were treated with controlled passive motion rehabilitation. The animals were killed at 3 weeks, at which time the tendons were tested for range of motion with a motion analysis system and for tensile properties with a materials testing machine. Proximal interphalangeal joint and distal interphalangeal joint rotation values were significantly higher for the PDGF-BB-treated tendons compared with the repair-alone tendons. Excursion values were also significantly higher in the PDGF-BB-treated tendons. There were no significant differences in tensile properties when comparing PDGF-BB-treated with repair-alone tendons. The functional properties of repaired intrasynovial flexor tendons were significantly improved with the sustained administration of PDGF-BB. The failure to achieve improvements in ultimate load, stiffness, and strain in the experimental group may have been due to suboptimal PDGF-BB dosage or suboptimal release kinetics.

    The minimum growth rate capable of supporting plasmid-encoded gene expression is determined using continuous cultures of Escherichia coli MZ9387 at dilution rates (D) as low as 5% of the maximum specific growth rate. Expression from a low copy number plasmid, pMPR166, encoding cyanase under the control of P(lac) is investigated in order to study plasmid-encoded gene expression under conditions approaching starvation. Plasmid copy number was stabilized by selection in the presence of 500 micrograms/mL chloramphenicol by constitutive expression of chloramphenicol acetyl transferase (CAT). Plasmid retention was determined by dot-blot hybridization and chloramphenicol resistance. The contribution of plasmid maintenance and cyanase expression to the maximum cell yield (Y'x/s) and the maintenance coefficient (ms) was determined for MZ9387 and MZ9387:pMPR166 under uninduced and IPTG-induced conditions. The values of Y'x/s and ms for non-plasmid-bearing cultures were 0.56 g of cell dry mass (DCM)/g of glucose and 0.26 g of glucose/g of DCM.h, respectively. The cell yield for plasmid-bearing cultures under uninduced conditions (Y 0'x/s) was 0.28 g of DCM/g of glucose, with m0s = 0.08 g of glucose/g of DCM.h. These values decreased following induction of cyanase expression. Glucose consumption in the presence of IPTG was linearly related to the growth rate at D cyanase expression alters metabolism and glucose consumption. The fraction of plasmid-free cells decreased with decreasing Damköhler number (Da). These data confirm the usefulness of Da for predicting the relationship between plasmid-free and plasmid-bearing cells where plasmids are stabilized by concentrations of antibiotic greater than the minimum plasmid-free host cell growth inhibitory concentration. Specific cyanase expression increased as the dilution rate decreased to D = 0.15 h-1. Between D = 0.15 h-1 and D = 0.14 h-1, expression decreased 7-fold. At very low dilution rates (D < or = 0.06 h-1), nonseptated

    Since the early 1980s our preception of sustainability has fundamentally changed. History sustainability was primarily concerned with the scarcity of natural resources in the face of a growing world population. Awareness of ecological and environmental degradations has come gradually. At first the solution to environmental problems such as global warming, ozone layer depletion, and hazardous waste appeared to require a halt in global economic growth. However creative solutions which address environmental issues and produce economic growth have come to the fore. This paper focuses this with respect to the clean-up of contaminated sites - remediation and case studies.

    The 2016 RAD-AID Conference analyzed the accelerated global activity in the radiology community that is transforming medical imaging into an effective spearhead of health care capacity building in low- and middle-income countries. Global health efforts historically emphasized disaster response, crisis zones, and infectious disease outbreaks. However, the projected doubling of cancer and cardiovascular deaths in developing countries in the next 15 years and the need for higher technology screening and diagnostic technologies in low-resource regions, as articulated by the United Nations' new Sustainable Development Goals of 2016, is heightening the role of radiology in global health. Academic US-based radiology programs with RAD-AID chapters achieved a threefold increase in global health project offerings for trainees in the past 5 years. RAD-AID's nonprofit radiology volunteer corps continue to grow by more than 40% yearly, with a volunteer base of 5,750 radiology professionals, serving in 23 countries, donating close to 20,000 pro bono hours globally in 2016. As a high-technology specialty interfacing with nearly all medical and surgical disciplines, radiology underpins vital health technology infrastructure, such as digital imaging archives, electronic medical records, and advanced diagnosis and treatment, essential for long-term future health care capacity in underserved areas of the world.

  20. The macroecology of sustainability.

    Directory of Open Access Journals (Sweden)

    Joseph R Burger

    Full Text Available The discipline of sustainability science has emerged in response to concerns of natural and social scientists, policymakers, and lay people about whether the Earth can continue to support human population growth and economic prosperity. Yet, sustainability science has developed largely independently from and with little reference to key ecological principles that govern life on Earth. A macroecological perspective highlights three principles that should be integral to sustainability science: 1 physical conservation laws govern the flows of energy and materials between human systems and the environment, 2 smaller systems are connected by these flows to larger systems in which they are embedded, and 3 global constraints ultimately limit flows at smaller scales. Over the past few decades, decreasing per capita rates of consumption of petroleum, phosphate, agricultural land, fresh water, fish, and wood indicate that the growing human population has surpassed the capacity of the Earth to supply enough of these essential resources to sustain even the current population and level of socioeconomic development.

    An animal protein-free medium was developed for Drosophila melanogaster S2 (S2AcGPV2) cells genetically modified to produce the rabies virus G glycoprotein (GPV). IPL-41, used as a basal medium, was supplemented with yeastolate, carbohydrates, amino acids and lipids aiming initially to reduce and further to eliminate the need of fetal bovine serum. The S2AcGPV2 cells were fully capable of growing in serum-free supplemented IPL-41 medium containing 6 g L(-1) yeastolate ultrafiltrate, 10 g L(-1) glucose, 3.5 g L(-1) glutamine, 0.5 g L(-1) fructose, 2 g L(-1) lactose, 0.6 g L(-1) tyrosine, 1.48 g L(-1) methionine and 1% (v/v) lipid emulsion, reaching 19 x 10(6) cells mL(-1). Maximum specific growth rate and cell productivity were 0.025 h(-1) and 0.57 x 10(5) cells mL(-1) h(-1), respectively. Glucose and lactose were consumed during cell culture, but not fructose. Lactate concentration generally decreased during cell culture, while ammonium concentration reached 167 mg L(-1), however, without noticeable deleterious effects on cell growth. GPV concentration values achieved were, however, modest in the proposed medium formulation.

    Full Text Available In recent decades, the image of the international business environment has changed significantly. Studies conducted by UNCTAD shows that corporate phenomenon developments in the world economy is growing. Without claiming to present an exhaustive topic so vast we tried to capture some "facets" of sustainable development from the perspective of multinational corporations, given the expansion of these economic entities and strengthening their power in the global economy. We present more negative aspects of the actions of multinational corporations in terms of sustainable development, it is very important to know both sides of the coin, which will not only help transnational giants including release. Based on issues such as corporate social responsibility, environmental pollution and workers' rights, we sought to counter official statements. The conclusion is that these economic entities are real forces that can not be ignored in today's world and the obvious problem of sustainable development can not be addressed independently of the phenomenon, context we also identified some possible solutions to conflict of corporations and essence of the concept of sustainable development.

    Full Text Available Even if sustainable development is a concept that gained quite recently its scientific prestige, through contribution of researchers its content has upgraded to a high degree of conceptual luggage and, through contribution from governance representatives, has gained an impressive good-practice background. Allowing the use of different methodological premises and conceptual tools, sustainable development paradigm is equipped with all the elements that would allow the opening of new horizons of knowledge. Based on the facility which can operate the concept of sustainable development, the European Union aims to develop both a more competitive economy based on environmental protection as well as a new governance of economic policy. This on one hand demonstrates the sustainable development ability to irradiate creativity towards the establishment of interdisciplinary bridges and on the other hand explains the growing interest of researchers interested in the problem of analyzing in detail this fruitful concept. Launched first as a theoretical framework to serve justify actions responsible for weighting economic growth, the concept of Sustainable Development has quickly become a topic of ethical debate circumscribed to the area of perfectibility of human nature to the necessity registry. In this regard, the philosophical content of this paradigm could not remain outside researchers concerns, who want to provide both policy makers and the general public a wide range of evidence to demonstrate the viability of this paradigm. Academia waits until maximization of the contribution of governance to achieve sustainable economic development, which consists in conjunction of this upward path with the momentum given by public policy sync, perfectly adapted for globalization era and all crises to come. However, because this concept based its structure and composition on three pillars, equally important economy, society and environment any attempt to strengthen

    Tolerance to defoliation can be defined as the degree to which productivity is affected by photosynthetic area reduction. This trait was studied in grain amaranth (Amaranthus cruentus and A. hypochondriacus), which are considered to be a highly defoliation-tolerant species. The physiological and biochemical responses to increasing levels of mechanical leaf removal up to total defoliation were quantified. Tolerance appeared to be dependent on various factors: ( i) amount of lost tissue; (ii) mechanics of leaf tissue removal; (iii) environment, and (iv) species tested. Thus, grain amaranth was found to be a highly tolerant species under green-house conditions when leaf tissue loss was performed by gradual perforation. However, tolerance was compromised under similar conditions when defoliation was done by gradual cutting of the leaf. Also tolerance in completely defoliated plants tended to decrease under field conditions, where differences between A. cruentus and A. hypochondriacus were observed. All non-structural carbohydrate (NSC) levels were reduced in stems and roots of totally defoliated amaranths one day after treatment. Such depletion probably provided the carbon (C) resources needed to sustain the early recovery process in the absence of photosynthetic capacity. This was corroborated by shading of intact plants, which produced the same rapid and drastic reduction of NSC levels in these tissues. These results emphasize the role of stored NSCs, particularly starch, in buffering the impact of severe defoliation in amaranth. The fall in sucrose synthase and cell wall invertase activity observed in stems and roots soon after defoliation was consistent with their predicted shift from sink to source tissues. It is concluded that mobilization of C stores in stems and roots, is a physiologically important trait underlying tolerance to defoliation in grain amaranth. PMID:23861825

    High-dose recombinant human growth hormone (rhGH) (2-6 mg/day) regimes may facilitate T-cell restoration in patients infected with human immunodeficiency virus (HIV) on highly active antiretroviral therapy (HAART). However, high-dose rhGH regimens increase insulin-like growth factor-I (IGF......-I) to supra-physiological levels associated with severe side effects. The present study investigated whether lower doses of rhGH may improve T-cell restoration in patients infected with HIV following an expedient response of total and bioactive (i.e., free) IGF-I.

    Full Text Available This study develops a biennial Malmquist–Luenberger  productivity index that is used to measure the sources of economic growth by utilizing data envelopment analysis and the directional distance function. Taking restrictions on resources and the environment into account based on the green growth accounting framework; we split economic growth into seven components: technical efficiency change, technological change, labor effect, capital effect, energy effect, output structure effect and environmental regulation effect. Further, we apply the Silverman test and Li-Fan-Ullah nonparametric test in combination with kernel distribution to test for the counterfactual contributions at the provincial level in China from 1998 to 2012. The empirical results show that: (1 technological progress and TFP make positive contributions to economic growth in China, while technical efficiency drags it down; (2 the effect of output structure and CO2 emissions with environmental regulation restrain economic growth in some provinces; and (3 overall, physical capital accumulation is the most important driving force for economic take-off, irrespective of whether the government adopts environmental regulations.

  12. Molecular beam epitaxy of GaAs nanowires and their sustainability for optoelectronic applications. Comparing Au- and self-assisted growth methods

    Energy Technology Data Exchange (ETDEWEB)

    Breuer, Steffen

    2011-09-28

    In this work the synthesis of GaAs nanowires by molecular beam epitaxy (MBE) using the vapour-liquid-solid (VLS) mechanism is investigated. A comparison between Au- and self-assisted VLS growth is at the centre of this thesis. While the Au-assisted method is established as a versatile tool for nanowire growth, the recently developed self-assisted variation results from the exchange of Au by Ga droplets and thus eliminates any possibility of Au incorporation. By both methods, we achieve nanowires with epitaxial alignment to the Si(111) substrates. Caused by differences during nanowire nucleation, a parasitic planar layer grows between the nanowires by the Au-assisted method, but can be avoided by the self-assisted method. Au-assisted nanowires grow predominantly in the metastable wurtzite crystal structure, while their self-assisted counterparts have the zincblende structure. All GaAs nanowires are fully relaxed and the strain arising from the lattice mismatch between GaAs and Si of 4.1 % is accommodated by misfit dislocations at the interface. Self-assisted GaAs nanowires are generally found to have vertical and non-polar side facets, while tilted and polar nanofacets were described for Au-assisted GaAs nanowires. We employ VLS nucleation theory to understand the effect of the droplet material on the lateral facets. Optoelectronic applications require long minority carrier lifetimes at room temperature. We fabricate GaAs/(Al,Ga)As core-shell nanowires and analyse them by transient photoluminescence (PL) spectroscopy. The results are 2.5 ns for the self-assisted nanowires as well as 9 ps for the Au-assisted nanowires. By temperature-dependent PL measurements we find a characteristic activation energy of 77 meV that is present only in the Au-assisted nanowires. We conclude that most likely Au is incorporated from the droplets into the GaAs nanowires and acts as a deep, non-radiative recombination centre.

    Peroxisome proliferator activated receptor α (PPARα) stimulates hepatocellular proliferation is species-specific. Activation of mouse, but not human, PPARα induces hepatocellular proliferation, hepatomegaly, and liver cancer. Here we tested the hypothesis that human and mouse PPARα affects liver regeneration differentially. PPARα-humanized mice (hPPARα(PAC)) were similar to wild type mice in responding to fasting-induced PPARα signaling. However, these mouse livers failed to regenerate in response to partial hepatectomy (PH). The liver-to-body weight ratios did not recover even 3 months after PH in hPPARα(PAC). The mouse PPARα-mediated down-regulation of let-7c was absent in hPPARα(PAC), which might partially be responsible for impaired proliferation. After PH, hPPARα(PAC) displayed steatosis, necrosis, and inflammation mainly in periportal zone 1, which suggested bile-induced toxicity. Quantification of hepatic bile acids (BA) revealed BA overload with increased hydrophobic BA in hPPARα(PAC). Forced FGF21 expression in partial hepatectomized hPPARα(PAC) reduced hepatic steatosis, prevented focal necrosis, and restored liver mass. Compared to mouse PPARα, human PPARα has a reduced capacity to regulate metabolic pathways required for liver regeneration. In addition, FGF21 can compensate for the reduced ability of human PPARα in stimulating liver regeneration, which suggests the potential application of FGF21 in promoting hepatic growth in injured and steatotic livers in humans.

    Full Text Available In four ways, massively multiplayer online role-playing games may serve as tools for advancing sustainability goals, and as laboratories for developing alternatives to current social arrangements that have implications for the natural environment. First, by moving conspicuous consumption and other usually costly status competitions into virtual environments, these virtual worlds might reduce the need for physical resources. Second, they provide training that could prepare individuals to be teleworkers, and develop or demonstrate methods for using information technology to replace much transportation technology, notably in commuting. Third, virtual worlds and online games build international cooperation, even blending national cultures, thereby inching us toward not only the world consciousness needed for international agreements about the environment, but also toward non-spatial government that cuts across archaic nationalisms. Finally, realizing the potential social benefits of this new technology may urge us to reconsider a number of traditional societal institutions.

    Downs, R. R.; Chen, R. S.

    2013-12-01

    Sustainability science (SS) is an 'emerging field of research dealing with the interactions between natural and social systems, and with how those interactions affect the challenge of sustainability: meeting the needs of present and future generations while substantially reducing poverty and conserving the planet's life support systems' (Kates, 2011; Clark, 2007). Bettencourt & Kaur (2011) identified more than 20,000 scientific papers published on SS topics since the 1980s with more than 35,000 distinct authors. They estimated that the field is currently growing exponentially, with the number of authors doubling approximately every 8 years. These scholars are undoubtedly using and generating a vast quantity and variety of data and information for both SS research and applications. Unfortunately we know little about what data the SS community is actually using, and whether or not the data that SS scholars generate are being preserved for future use. Moreover, since much SS research is conducted by cross-disciplinary, multi-institutional teams, often scattered around the world, there could well be increased risks of data loss, reduced data quality, inadequate documentation, and poor long-term access and usability. Capabilities and processes therefore need to be established today to support continual, reliable, and efficient preservation of and access to SS data in the future, especially so that they can be reused in conjunction with future data and for new studies not conceived in the original data collection activities. Today's long-term data stewardship challenges include establishing sustainable data governance to facilitate continuing management, selecting data to ensure that limited resources are focused on high priority SS data holdings, securing sufficient rights to allow unforeseen uses, and preparing data to enable use by future communities whose specific research and information needs are not yet known.

Economic development includes economic growth, quantified in particular through the GDP, aspect that leads to a reduced analysis taking into account a limited number of variables such as household income, employment labour, consumption of goods and services, etc.. Perpetuation of this model has led, over time, to the company's inability to solve the problems facing mankind today and serious discrepancies regarding current levels of human development. This type of model does not take into account variables such as unemployment, poverty, education, health, environmental pollution, population migration, urban overcrowding, social inclusion etc. At the opposite side of this type of development, which proves to be beyond the crowd problems currently facing humanity, is a new alternative model, that of sustainable development, which provides an integrated view of all these variables and hence the chance of the human society to a new level of evolution. The sustainable development model of mankind put, among others, the zero growth issue or even sustained decrease for some countries. This model requires also reducing resource consumption and increase sustainability of assets created. It also offers practical solutions to many current problems of mankind, among which we can mention providing food for a growing world population and producing clean alternative energy.

  12. Sustainable Scientists

    Mills, Evan

    2008-12-31

    Scientists are front and center in quantifying and solving environmental problems. Yet, as a spate of recent news articles in scientific journals point out, much can be done to enhance sustainability within the scientific enterprise itself, particularly by trimming the energy use associated with research facilities and the equipment therein (i,ii,iii, iv). Sponsors of research unwittingly spend on the order of $10 billion each year on energy in the U.S. alone, and the underlying inefficiencies drain funds from the research enterprise while causing 80 MT CO2-equivalent greenhouse-gas emissions (see Box). These are significant sums considering the opportunity costs in terms of the amount of additional research that could be funded and emissions that could be reduced if the underlying energy was used more efficiently. By following commercially proven best practices in facility design and operation, scientists--and the sponsors of science--can cost-effectively halve these costs, while doing their part to put society on alow-carbon diet.

The national S&T priorities for countries are systemized and a comparative assessment of capacities for S&T development in BRICS countries is developed. Indicators of publication activity of all BRICS countries have significantly increased since 2000. Analysis shows that Russia must pay particular attention to the development of cooperation with China, which is already one of the leaders on the global S&T stage. Cooperation with India, Brazil and, in some research areas, with South Africa could also have a positive impact on the performance of research and development in Russia. A list of 14 thematic priorities for S&T cooperation for BRICS countries is presented in the paper based on the analysis of a set of national, bilateral and multilateral strategic and forward-looking documents. Priorities of S&T development create a basis for more efficient and mutually beneficial cooperation between BRICS countries and allows individual scientists to broaden the range of research, use new tools for S&T cooperation and share best practices.

    2013-08-01

    Full Text Available The word “sustainability” is often used in business in the belief that the current ways of doing things will be able to be continued with only minor changes to balance economic development with related environmental and social issues. There are, however, immense challenges that threaten the very sustainability of our global society, let alone individual businesses or developments. A few of the most important of these challenges—population growth, clean energy supply, fresh water availability, and global climate change—are discussed. As humanity forms its collective response to these threats, it is concluded that all intelligent people, but especially scientists, have important roles to play, not only in technical innovation, but also in catalyzing political action.

    2010-01-01

    Groundwater extraction has facilitated significant social development and economic growth, enhanced food security and alleviated drought in many farming regions. But groundwater development has also depressed water tables, degraded ecosystems and led to the deterioration of groundwater quality, as well as to conflict among water users. The effects are not evenly spread. In some areas of India, for example, groundwater depletion has preferentially affected the poor. Importantly, groundwater in some aquifers is renewed slowly, over decades to millennia, and coupled climate–aquifer models predict that the flux and/or timing of recharge to many aquifers will change under future climate scenarios. Here we argue that communities need to set multigenerational goals if groundwater is to be managed sustainably.

  9. Sustainability. An economic perspective

    Energy Technology Data Exchange (ETDEWEB)

    Elliott, Steven R. [Department of Economics and Center for Sustainable Systems Studies, Miami University, Oxford, OH (United States)

    2005-06-15

    The economic perspective of sustainability focuses on the trade off of current consumption for future consumption. This was the question that faced the economists of the late 19th century such as Malthus who noticed growth in the population outpaced that of food. Yet, Malthusian prediction of famine and disaster did not come to pass due to technological innovation. There was a substitution of created capital (machines) for natural capital (labor and land). Thus, whether created- and natural capital are substitute or complementary goods is key to sustainability. Many economists believe we can maintain current consumption and that technological innovation will take care of the needs of future generations. However other economists believe that created capital and natural capital are complementary goods; as we consume more created capital, we will also have to consume more natural capital. The relationship between natural and created capital has an impact on what policies and incentives we consider for the preservation of opportunities for future generations. If they are substitutes, current efforts need to focus on development of new technologies which will allow us to do more with less. If they are complements we need to consider efforts of preservation and conservation. We understand that we cannot have our cake and eat it too. The debate is whether we emphasize finding a new way to bake more cake, or carefully consume the cake we have.

  10. Creating sustainable performance.

    2012-01-01

    What makes for sustainable individual and organizational performance? Employees who are thriving-not just satisfied and productive but also engaged in creating the future. The authors found that people who fit this description demonstrated 16% better overall performance, 125% less burnout, 32% more commitment to the organization, and 46% more job satisfaction than their peers. Thriving has two components: vitality, or the sense of being alive and excited, and learning, or the growth that comes from gaining knowledge and skills. Some people naturally build vitality and learning into their jobs, but most employees are influenced by their environment. Four mechanisms, none of which requires heroic effort or major resources, create the conditions for thriving: providing decision-making discretion, sharing information about the organization and its strategy, minimizing incivility, and offering performance feedback. Organizations such as Alaska Airlines, Zingerman's, Quicken Loans, and Caiman Consulting have found that helping people grow and remain energized at work is valiant on its own merits-but it can also boost performance in a sustainable way.

  11. Engineering sustainable development

    Energy Technology Data Exchange (ETDEWEB)

    Deitz, D.

    1996-05-01

    This article describes how engineers are forming alliances on the job, in communities, and in international organizations to accelerate economic development while they preserve resources and the environment. Despite the end of the Cold War and the rapid economic development in Asia and Latin America, anxiety abounds as the 21st century dawns. The growth rate of the world`s population remains frighteningly high, and the Earth`s atmosphere appears endangered. Even rays of hope, such as the surge in China`s and India`s economies, cast a shadow on the future by threatening to deplete natural resources even further. In the face of such overwhelming conditions, individual effort may seem futile. There are signs, however, that people are joining forces to do what they can within the limits of what is technologically and economically possible. Although many of them are driven by idealism, a good number are participating to make business more efficient and profitable as well as to enhance their nation`s industrial competitiveness. Their model for change and growth is one that doesn`t endanger the environment--a concept that has come to be known as sustainable development. In the process, engineers are leaving the isolation of their laboratories and individual disciplines to educate, invent, inspire, and join forces with other engineers, community groups, environmentalists, business and labor leaders, and government officials. One sign that such collaborative efforts are succeeding--in addition to the tangible results--is the evolution in thinking about sustainable development, as it applies both to today`s world and to future generations.

    2014-02-01

    The concept of sustainability has been an integral part of development work since the late 1970s. Sustainability is no longer a buzzword but a reality that must be addressed by cities all over the world. Increasing empirical evidence indicates that city sustainability is not just related to technical issues, such as carbon emissions, energy consumption and waste management, or on the economic aspects of urban regeneration and growth, but also it covers social well-being of different groups living within increasingly cosmopolitan towns and cities. Heritage is seen as a major component of quality of life, features that give a city its unique character and provide the sense of belonging that lies at the core of cultural identity. In other words, heritage by providing important social and psychological benefits enrich human life with meanings and emotions, and raise quality of life as a key component of sustainability. The purpose of this paper, therefore, is to examine the role that built cultural heritage can play within sustainable urban development.

    Full Text Available The paper substantiates an innovation constituent of sustainable development along with environmental, social and economic pillars of the concept. Determining of implementation details of innovation activity by J. Schumpeter is a theoretical prerequisite to understanding of innovation constituent. An innovator-entrepreneur provides a customer with an information image of 'new combinations.' The image is created by identifying customer's future needs, which outline business aims, subject and appropriate means for creating the innovation products. However, consumer choice is largely motivated by values and specific rules of behavior. The rules of consumer society that in the industrial age become the motive, morality and institution, did not consider the reproductive capabilities of the environment. This disagreement was previously presented in The Limits to Growth by the Club of Rome and was reflected in the concept of sustainable development, which gained immense significance after the report of the World Commission on Environment and Development in 1987 (Our Common Future. The study highlights importance for establishment of new social values that motivate innovators to change their thinking, comprehend their responsibility not only to consumers but also to the environment and future generations. The Rio+20 Corporate Sustainability Forum: Innovation and Collaboration for the Future We want, organized by the UN Global Compact, demonstrates the interest of entrepreneurs in practical implementation of the concept of sustainable development, through an effective innovation activity.

    Ridsdale, D Reanne; Noble, Bram F

    2016-12-15

    The remediation industry has grown exponentially in recent decades. International organizations of practitioners and remediation experts have developed several frameworks for integrating sustainability into remediation projects; however, there has been limited attention to how sustainability is approached and operationalized in sustainable remediation frameworks and practices - or whether sustainability plays any meaningful role at all in sustainable remediation. This paper examines how sustainability is represented in remediation frameworks and the guidance provided for practical application. Seven broad sustainability principles and review criteria are proposed and applied to a sample of six international remediation frameworks. Not all review criteria were equally satisfied and none of the frameworks fully met all criteria; however, the best performing frameworks were those identified as sustainability remediation frameworks. Intra-generational equity was addressed by all frameworks. Integrating social, economic and biophysical components beyond triple-bottom-line indicators was explicitly addressed only by the sustainable remediation frameworks. No frameworks provided principle- or rule-based guidance for dealing with trade-offs in sustainability decisions. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The nature of our major global risks calls for sustainable innovations to decouple economic growth from greenhouse gases emission. The development of sustainable technologies has been negatively impacted by several factors including sugar production costs, production scale, economic crises, hydraulic fracking development and the market inability to capture externality costs. However, advances in engineering of biological systems allow bridging the gap between exponential growth of knowledge about biology and the creation of sustainable value chains for a broad range of economic sectors. Additionally, industrial symbiosis of different biobased technologies can increase competitiveness and sustainability, leading to the development of eco-industrial parks. Reliable policies for carbon pricing and revenue reinvestments in disruptive technologies and in the deployment of eco-industrial parks could boost the welfare while addressing our major global risks toward the transition from a fossil to a biobased economy.

    2016-06-01

    Full Text Available The aim of this research is to investigate China’s urban green total factor productivity (TFP under the background of progressing urbanization and intensifying environmental pollution, and found out its main influencing factors. In this paper, green TFP of 285 prefecture-level cities in China from 2005 to 2012 was estimated through Malmquist productivity index. Results showed that the annual growth of green TFP in main cities in China is 3.5% and the overall growth declines gradually. Viewed from decomposition of green TFP, technical progress is the main contributor of green TFP growth. Furthermore, the northern coastal region has achieved the highest annual growth of green TFP (4.5% and the northwest region achieved the lowest growth of green TFP (1.24%, indicating the great regional differences of green TFP and economic growth quality in China. According to analysis on influencing factors of green TFP in main cities, it has been concluded that per-capita urban road area, number of Internet users, proportion of fiscal expenditures, environmental regulation level and technical input are significantly positively correlated with green TFP, while industrial structure and foreign direct investment (FDI are significantly negatively correlated. Finally, policy suggestions to improve urban green TFP in China were proposed.

    / It is legitimate to ask whether and in what form tourism might contribute to sustainable development. This is not the same as sustainable tourism which, as a single-sector approach to development, may overlook important linkages with other sectors. If tourism is to contribute to sustainable development, then it must be economically viable, ecologically sensitive and culturally appropriate. Ecotourism is often advocated as being a sustainable form of tourism but imprecision in terminology clouds basic issues and there are strong economic, ecological, and cultural reasons for believing that, even in its purest forms, ecotourism is likely to present substantial challenges to destination areas, particularly if it competes for scarce resources and displaces existing uses and users. Sustainable tourism and ecotourism are not synonyms, many forms of ecotourism may not be sustainable, and if ecotourism is to contribute to sustainable development, then careful planning and management will be required.KEY WORDS: Ecotourism; Sustainable development; Development; Tourism

    2014-05-01

    Full Text Available Improvement of the sustainability in the farming sector is a core objective of the European Union which generates important consequences on the life’s quality. The sustainable agriculture has to bring an own contribution to the raising of the food safety and security, development and revitalize rural areas, environmental protection.In Romania improving the sustainability features of the agricultural practices is an ongoing preoccupation of the making cisional factors, the sustainable development being introduced in the national strategies and implemented in the practice by the agricultural holdings. This paper investigates the main characteristics of sustainability of Romanian agriculture having in view the three pillars of sustainable development, namely, economic aspects, social aspects and environmental aspects. For achieving this purpose it is carried out a dynamic analysis of the holdings’ economy which have a commercial profile from Romania and the other EU new member states. The analysis results reveal the contribution of some production factors on the economic efficiency to sustainable growth of holdings. The study findings suggest the action directions that have to be addressed by the decisional factors in order to consolidate the sustainability of farming practices.

    Kumar, Manish; Tomar, Rajesh Singh; Lade, Harshad; Paul, Diby

    2016-07-01

    Excessive use of chemical fertilizers to increase production from available land has resulted in deterioration of soil quality. To prevent further soil deterioration, the use of methylotrophic bacteria that have the ability to colonize different habitats, including soil, sediment, water, and both epiphytes and endophytes as host plants, has been suggested for sustainable agriculture. Methylotrophic bacteria are known to play a significant role in the biogeochemical cycle in soil ecosystems, ultimately fortifying plants and sustaining agriculture. Methylotrophs also improve air quality by using volatile organic compounds such as dichloromethane, formaldehyde, methanol, and formic acid. Additionally, methylotrophs are involved in phosphorous, nitrogen, and carbon cycling and can help reduce global warming. In this review, different aspects of the interaction between methylotrophs and host plants are discussed, including the role of methylotrophs in phosphorus acquisition, nitrogen fixation, phytohormone production, iron chelation, and plant growth promotion, and co-inoculation of these bacteria as biofertilizers for viable agriculture practices.

  8. Sustainable development: women as partners.

    Science.gov (United States)

    Dem, M

    1993-02-01

    The economic recession and the structural adjustment programs imposed y the International Monetary Fund have caused sluggish or no economic growth and a decline in living conditions in sub-Saharan Africa. Senegal's New Agricultural Policy has eliminated subsidies for agricultural inputs, worsening the already declining living conditions. Population growth in Senegal exceeds food production; it is very rapid in cities (urban growth rate, 2.7%). Women, especially, suffer from the economic crisis; it increases the burden on women for income generation, but the increased workload does not equate more income. This workload restricts women's opportunities to improve their physical environment and does not improve their status within society. Women still face discrimination daily; power lies with men. Oxfam supports urban women financially and technically as they organize and pursue income generation activities to institute change leading to sustainable development. It has helped a Serere women's group in Dakar to organize and provided credit funds to support their trading activities and family planning sensitization training. Oxfam also finances rural women coming to Dakar during the dry season to pound millet to sell. Problems which have to be overcome to achieve sustainable development acceptable to women are numerous. Women need access to the ways and means of food production. Resources are insufficient and inaccessible to women because women are excluded from the decision-making process. Women generally do not have access to information and training which would help them make their own choices and manage their own lives. Political and sociocultural environments, especially those of the poor, do not easily allow women opportunities for independent reflection and expression. Grassroots women's groups provide the best base to develop female solidarity and women's representation, leading to sustainable development. Development organizations must take up a new dynamic

  15. A territorial understanding of sustainability in public development

    Energy Technology Data Exchange (ETDEWEB)

    Peti, Marton, E-mail: mpeti@vati.hu

    2012-01-15

    Sustainability theories in European Union (EU) development policies are facing significant challenges: it is difficult to transmit context-specific, publicly communicable messages; the recent development policies strengthen the concurrent development paradigm of economic growth and competitiveness; 'climate change' became a more popular environmental integration term than sustainability in the last few years. However, due to the recent crises of the economic growth, there is a great chance to reintroduce a sustainability-based development. A territorial/regional understanding of sustainability can also be an answer for the current challenges, a platform for refreshing the concept with relevant, specific messages that are close to the everyday life. This paper summarises the 'territorial system'-based basic principles of territorial sustainability in a model called AUTHARSIIV (AUTonomy, HARmony, Solidarity, Innovation, Identity and Values). This is a supplementary sustainability content specified for the context of spatial/regional development or planning. The paper also examines the presence of 'general and territorial sustainability' in regional development programmes, and case studies on applying the territorial sustainability principles in planning, assessment, and implementation. According to the results, sustainability is rarely adapted to the conditions of a given sector or a region, and the territorial aspect of sustainability is underrepresented even in territorial programmes. Therefore, the paper proposes a new planning and assessment system that is based on a set of regionally legitimate sustainability values.

  16. Health and sustainability.

    Science.gov (United States)

    Kjӕrgård, Bente; Land, Birgit; Bransholm Pedersen, Kirsten

    2014-09-01

    In the present article, we explore how sustainable development strategies and health promotion strategies can be bridged. The concept of the 'duality of structure' is taken as our starting point for understanding the linkages between health promotion and sustainable development, and for uncovering the structural properties or conditions which either enable or constrain sustainable public health initiatives. We argue that strategies towards health promotion are not sufficiently integrated with strategies for sustainable development, and thus political strategies aimed at solving health problems or sustainability problems may cause new, undesired and unforeseen environmental or health problems. First, we explore how the relation between health and sustainability is articulated in international policy documents. Next, we develop a model for understanding the relation between health promotion and sustainability. Third, we use examples from agriculture and food production to illustrate that health and sustainability are mutually enabling and constraining. We conclude that while the renewed focus on food security and food inequalities has brought the health and sustainability dimensions of the food system onto the political agenda, the conceptualization of duality between health and sustainability could be a new platform for a critical and theoretical stance towards the market-oriented food system strategy. Thinking along the lines of duality means that the integration of health promotion strategies and sustainable development strategies cannot be based on an approach to integration in which either health or sustainability is given precedence over the other. From a duality perspective, integration means conceiving sustainability from a health perspective and health from a sustainability perspective. © The Author (2013).

    Full Text Available Technology analysis (TA is an important issue in the management of technology. Most R&D (Research & Development policies have depended on diverse TA results. Traditional TA results have been obtained through qualitative approaches such as the Delphi expert survey, scenario analysis, or technology road mapping. Although they are representative methods for TA, they are not stable because their results are dependent on the experts’ knowledge and subjective experience. To solve this problem, recently many studies on TA have been focused on quantitative approaches, such as patent analysis. A patent document has diverse information of developed technologies, and thus, patent is one form of objective data for TA. In addition, sustainable technology has been a big issue in the TA fields, because most companies have their technological competitiveness through the sustainable technology. Sustainable technology is a technology keeping the technological superiority of a company. So a country as well as a company should consider sustainable technology for technological competition and continuous economic growth. Also it is important to manage sustainable technology in a given technology domain. In this paper, we propose a new patent analysis approach based on statistical analysis for the management of sustainable technology (MOST. Our proposed methodology for the MOST is to extract a technological structure and relationship for knowing the sustainable technology. To do this, we develop a hierarchical diagram of technology for finding the causal relationships among technological keywords of a given domain. The aim of the paper is to select the sustainable technology and to create the hierarchical technology paths to sustainable technology for the MOST. This contributes to planning R&D strategy for the sustainability of a company. To show how the methodology can be applied to real problem, we perform a case study using retrieved patent documents related to

    Sustainability is the theme of our time and also the grandest challenge to humanity. Since the 1970s, the term, sustainable development, has frequently appeared in the scientific literature, governmental documents, media promotions for public goods, and commercial advertisements. However, the science that provides the theoretical foundation and practical guidance for sustainable development--sustainability science--only began to emerge in the beginning of the 21st century. Nevertheless, the field has rapidly developed in depth and expanded in scope during the past decade, with its core concepts and research methods coalescing. China, as the most populous country in the world and home to the philosophical root of sustainability science-the unity of man and nature, is obligated to take upon the challenge of our time, to facilitate global sustainability while pursuing the Chinese Dream, and to play a leading role in the development of sustainability science. Toward this grandiose goal, this paper presents the first Chinese introduction to sustainability science, which discusses its basic concepts, research questions, and future directions. Sustainability science is the study of the dynamic relationship between humans and the environment, particularly focusing on the vulnerability, robustness, resilience, and stability of the coupled human-environment system. It is a transdisciplinary science that integrates natural sciences with humanities and social sciences. It hinges on the environment-economy-society nexus, and merges basic and applied research. The key components of sustainability often change with time, place, and culture, and thus sustainability science needs to emphasize multi-scale studies in space and time, with emphasis on landscapes and regions over a horizon of 50 to 100 years. It needs to focus on the relationship between ecosystem services and human well-being, as influenced by biodiversity and ecosystem processes as well as climate change, land use

    Full Text Available Purpose- The aim of this paper is to review and reflect on the sustainability agendas and achievements reported by Europe's leading food and drinks wholesalers. Design/Methodology/Approach- The paper begins with a short introduction to corporate sustainability, sustainability reporting and food and drinks wholesaling within Europe and the empirical material for the paper is drawn from reports and information posted on the leading food and drinks wholesalers' corporate websites. Findings- There are marked variations in the extent to which Europe's leading food and drinks wholesalers reported and provided information on their sustainability agendas and achievements. These agendas and achievements embraced a wide range of environmental, social and economic issues but the reporting process had a number of weaknesses that undermine its transparency and credibility. The authors also argue that the leading food and drinks wholesalers' definitions of, and commitments to, sustainability are principally driven by business imperatives as by any fundamental concern to maintain the viability and integrity of natural and social capital. More critically the authors argue that this approach is couched within existing business models centred on continuing growth and consumption Limitations- The paper is a preliminary review of the sustainability agendas and achievements publicly reported by Europe's leading food and drinks wholesalers. Originality- The role of Europe's wholesale sector in addressing sustainability has received scant attention in the academic literature and this paper will interest academics and students in business management and marketing and employees and executives working in the distribution sector of the economy.

    Energy-savings in the existing building stock have becomes a main goal in national and international policies. Often focus is on building-renovations, whereas the potential of sustainable building operation to a large extent has been neglected. Nevertheless, international research as well...... as practical experiences from Danish housing estates indicates that there are large potentials for energy savings by focusing on the operation of the buildings. We suggest that in order to achieve sustainability in the existing housing, renovation and operations should be seen as integrated parts...... and that sustainable building operation can pave the way for sustainable building renovation.

    ICT Innovations for Sustainability is an investigation of how information and communication technology can contribute to sustainable development. It presents clear definitions of sustainability, suggesting conceptual frameworks for the positive and negative effects of ICT on sustainable development. It reviews methods of assessing the direct and indirect impact of ICT systems on energy and materials demand, and examines the results of such assessments. In addition, it investigates ICT-based approaches to supporting sustainable patterns of production and consumption, analyzing them at various levels of abstraction – from end-user devices, Internet infrastructure, user behavior, and social practices to macro-economic indicators.   Combining approaches from Computer Science, Information Systems, Human-Computer Interaction, Economics, and Environmental Sciences, the book presents a new, holistic perspective on ICT for Sustainability (ICT4S). It is an indispensable resource for anyone working in the area of ICT...

  4. Sustainability and substitutability.

    Science.gov (United States)

    Fenichel, Eli P; Zhao, Jinhua

    2015-02-01

    Developing a quantitative science of sustainability requires bridging mathematical concepts from fields contributing to sustainability science. The concept of substitutability is central to sustainability but is defined differently by different fields. Specifically, economics tends to define substitutability as a marginal concept while fields such as ecology tend to focus on limiting behaviors. We explain how to reconcile these different views. We develop a model where investments can be made in knowledge to increase the elasticity of substitution. We explore the set of sustainable and optimal trajectories for natural capital extraction and built and knowledge capital accumulation. Investments in substitutability through knowledge stock accumulation affect the value of natural capital. Results suggest that investing in the knowledge stock, which can enhance substitutability, is critical to desirable sustainable outcomes. This result is robust even when natural capital is not managed optimally. This leads us to conclude that investments in the knowledge stock are of first order importance for sustainability.

    Full Text Available The growing concern over global warming and significant ecological changes requires sustainable development in all fields of science and technology. Concrete not only consumes huge amount of energy and natural sources, but also emits large amount of CO2, mainly due to the production of cement. It is evident that such large amount of concrete production has put significant impact on the energy, resource, environment, and ecology of the society. Hence, how to develop the concrete technology in a sustainable way has become a significant issue. In this paper, some of Korean researches for sustainable development of concrete are presented. These are sustainable strengthening for deteriorated concrete structure, sustainable reinforcement of new concrete structure, sustainable concrete using recycled aggregate and supplementary cementing materials and finally application of each technique to precast concrete.

  10. Sustainability assessment and complementarity

    Directory of Open Access Journals (Sweden)

    Hugo F. Alrøe

    2016-03-01

    Full Text Available Sustainability assessments bring together different perspectives that pertain to sustainability to produce overall assessments, and a wealth of approaches and tools have been developed in the past decades. However, two major problems remain. The problem of integration concerns the surplus of possibilities for integration; different tools produce different assessments. The problem of implementation concerns the barrier between assessment and transformation; assessments do not lead to the expected changes in practice. We aim to analyze issues of complementarity in sustainability assessment and transformation as a key to better handling the problems of integration and implementation. Based on a generalization of Niels Bohr's complementarity from quantum mechanics, we have identified two forms of complementarity in sustainability assessment, observer stance complementarity and value complementarity. Unlike many other problems of sustainability assessment, complementarity is of a fundamental character connected to the very conditions for observation. Therefore, complementarity cannot be overcome methodologically, only handled better or worse. Science is essential to the societal goal of sustainability, but these issues of complementarity impede the constructive role of science in the transition to more sustainable structures and practices in food systems. The agencies of sustainability assessment and transformation need to be acutely aware of the importance of different perspectives and values and the complementarities that may be connected to these differences. An improved understanding of complementarity can help to better recognize and handle issues of complementarity. These deliberations have relevance not only for sustainability assessment, but more generally for transdisciplinary research on wicked problems.

    Science, Innovation, and Partnerships for Sustainable Solutions: A National Academies Symposium; Washington, D. C., 16-18 May 2012 It is no longer disputed that humanity has drastically changed the face of the planet and its life-support systems. The sustainability challenge is to meet people's needs today and in the future while sustaining life-support systems. This grand challenge demands a new scientific approach: use-inspired, solution-driven research that consciously links scientific research to societal decision-making and action. Sustainability science may help fulfill that need if it can engage communities of expertise across a wide range of disciplines and sectors, including the geosciences.

  15. The Growth Delusion

    Directory of Open Access Journals (Sweden)

    Bob Lloyd

    2009-08-01

    Full Text Available Concern for the environment and a move towards “sustainable development” has assisted progress in a wide range of renewable energy technologies in recent years. The science suggests that a transition from fossil fuels to sustainable sources of energy in a time frame commensurate with the demise of the fossil fuels and prevention of runaway climate change is needed. However, while the movement towards sustainable energy technologies is underway, the World does not want to give up the idea of continuing economic growth. In recent times the financial collapse of October 2008 has given rise to yet another set of pleas from corporations and politicians alike to restart the growth machine. The transition to renewable energy technologies will be difficult to achieve as nowhere within existing economic and political frameworks are the limits to when growth will be curtailed being set. It is possible that the irrational insistence on endless growth as a non negotiable axiom, by a large proportion of the world’s population, may in fact be akin to the similarly irrational belief, by a similarly large proportion of the world’s population, that a supernatural being controls our existence and destiny. The irrationality of religion has recently been examined by Richard Dawkins in “The God Delusion”. Dawkins’ book is used as a starting point to investigate similarities between a belief in God and a belief in continuous growth.

    Even though the government of China has made much progress in controlling population growth, demographic momentum is such that the population of China is still increasing at a rate of about 16 million annually. By mid 1994, China had 1.19 billion people, making up more than 21% of the world's population. China adds about 24 million more people each year. This rapidly rising population is placing much pressure on natural resources and the environment. It is also a taxing obstacle for economic development. Huge population size, irregular age and sex structure, uneven geographic distribution, and much lower fertility and mortality rates than other developing countries at a similar level of socioeconomic development characterizes China's current population. The sex ratios are high (e.g., surplus of 16 million males 20 years old), especially for groups under age 10. In 1989, there was a deficit of 879,466 female births. 94% of the population lives in 36% of the territory (the east and southeast regions). The total fertility rate has fallen from 5.8 in 1970 to 2 in 1994. It is lowest in Shanghai and Beijing (about 1.3) and highest in Tibet (4.3). Natural increase has dropped from 26 to 11.9/1000 people. The size and proportion of the population 60 years and older is expected to increase from 98 million (8.6% of the total population) in mid 1990 to 412 million in 2050 (27.4% of the total population). Despite progress in improving the level of education, China still has 180 million illiterate and semiliterate people. Institutions of higher learning are experiencing a brain drain to developed countries and brain transfer to other sectors inside the country. The population policy and program should strive to realize a reasonable population structure and distribution and to develop human resources so China can meet its needs for sustainable development.

    Full Text Available The article points out that the progressive deterioration of the social and environmental situation on the planet and the emergence of the real threat of anthropo-ecological catastrophe necessitate the abandoning of the current model of civilizational development and the formation (first in theory and then in practice of an ultimately new one. This innovative strategy, which means taking account of the main socio-natural contradiction, is called a sustainable development strategy. This new form of civilizational development must become rationally governed on a planetary scale, thus providing the survival and temporal continuation of the existence of humans and biosphere. The authors regard sustainable development as a vitally important (later on - dominating orientation of international, political and global processes. This vision makes it crucially important to embed this conception into the proper scientific disciplines and research fields. The authors make use of the A.D. Bogaturov's conceptualization approach for the scientific discipline of world politics and consider the latter as an evolutionary form of global political development. The real global integrity of the world political system serves as a global attractor of this evolutionary transformation, and this aspect represents the specific pattern of all global processes. It is supposed that these processes will unfold through transition to sustainable development. The development of the global system of political actorship is considered a fundamental process within the growth of overall complexity of the global political structure. In the evolutionary sustainable development perspective it should result in the formation of an integral subject of global politics and global activity. The article shows that the dominating state-centric approach reproduces the political model of unsustainable development, which is characterized by archaic prerequisites of political realism, spontaneous

    Full Text Available Sustainable development of administrative-territorial units (ATU refers to the main directions of Russian Federation state policy to ensure the security of the national economy to meet the vital needs of people and the preservation of such a possibility for the future generations. The article describes and analyzes the factors that have the most significant impact on the level of ATE development. The dynamics of the gross output of agriculture in Russia and its critical evaluation are presents. It was revealed that the development of the region is the basis of the national economy security. At present, the concept of “sustainable development” in Russia is relevant and the role of regions in the sustainable development of the Russian Federation is constantly increasing. Stability of self-financing of the regional economy is achieved through conducting effective fiscal, financial, credit, tax and price policy, establishment of equal inter-budgetary relations with the federal center, the development of the securities market, increasing the volume of exports. Conducted research allowed: to identify the main factors influencing the sustainable development of Russia regions. The reasons for the backlog of economy of the Smolensk region of the nationwide growth rate and direction of their elimination are examined. Formation of the forecast of domestic agriculture development in the period up to 2020 should be based on the priority position of the industry in the agricultural sector, which is determined by its decisive role in meeting the population’s needs for basic food products. Prospective volumes of production of major agricultural products are based on the need to meet the challenges provided by the Russian Federation Government Decree.

In a universe with seriously exhausted natural resources, severe urbanization, climate change and conflicts that go beyond borders, the issue of overpopulation unquestionably causes worldwide debates and can generate a snowball effect for the global economy or human society. Population’s increase in the nearby future will have a central role in challenges such as: global warming, air and water contamination, increase in the level of poverty, food scarcity, deforestation, desertification, health problems and resource shortages. The transformation into a sustainable environmental model, situated in a post-carbon economy, will imply setting barriers to industrial progress (will have to be sustainable and environmental friendly and also to population growth (will have to follow a normal pace. But, the level on vulnerability and uncertainty in the evolution of energy has been threatened lately by major events that took place all around the world. Security of supply, new geopolitical perspectives and ecological and sustainability issues are yet again on the bleeding line. Therefore, the goal of this theoretical article is to give an overview of the current situation concerning the role of energy in ecological sustainability. It expresses routes in which humans and enterprises can act in order to contribute to ecologically sustainable development. The subject of how we live on a congested planet represents the most critical sustainability of all. We are witnessing our current risks and we can also envision our possible, and particularly desirable, future: a steady human population, living and protecting the nature and planet, having finite needs of goods, services, or energy, and maintaining a healthy Earth for us and the animals that also depend on it.

    The widely used concept of sustainability is seldom precisely defined, and its clarification involves making up one's mind about a range of difficult questions. One line of research (bottom-up) takes sustaining a system over time as its starting point and then infers prescriptions from...... this requirement. Another line (top-down) takes an economical interpretation of the Brundtland Commission's suggestion that the present generation's needsatisfaction should not compromise the need-satisfaction of future generations as its starting point.

    Full Text Available Sustainable energy development implies the need for the emerging potential energy sources which are not producing adverse effect to the environment. In this respect nuclear energy has gained the complimentary favor to be considered as the potential energy source without degradation of the environment. The sustainability evaluation of the nuclear energy systems has required the special attention to the criteria for the assessment of nuclear energy system before we can make firm justification of the sustainability of nuclear energy systems. In order to demonstrate the sustainability assessment of nuclear energy system this exercise has been devoted to the potential options of nuclear energy development, namely: short term option, medium term option, long term option and classical thermal system option. Criteria with following indicators are introduced in this analysis: nuclear indicator, economic indicator, environment indicator, social indicator... The Sustainability Index is used as the merit for the priority assessment among options under consideration.

    Sustainable design is a collective process whereby the built environment achieves unprecedented levels of ecological balance through new and retrofit construction, with the goal of long-term viability and humanization of architecture. Focusing on the environmental context, sustainable design merges the natural, minimum resource conditioning solutions of the past (daylight, solar heat, and natural ventilation) with the innovative technologies of the present.  The desired result is an integrated “intelligent” system that supports individual control with expert negotiation for resource consciousness. International experts in the field address the fundamental questions of sustainable design and landscape management: How should the sustainability of landscapes and buildings be evaluated? Which targets have to be set and which thresholds should not be exceeded? What forms of planning and governance structures exist and to what extent do they further the goals of sustainability?  Gathering 30 peer-reviewed ent...

  7. Urban development in Freiburg, Germany – sustainable and neoliberal?

    Directory of Open Access Journals (Sweden)

    Mössner, Samuel

    2015-09-01

    Full Text Available In recent years, sustainable urban development has emerged as a relevant but contested field in urban studies. A broad and diverse literature has discussed sustainable development from various perspectives. Some authors have researched urban sustainability from a technocratic perspective, looking for technical and managerial solutions. Others have shed light on the political dimension of urban sustainable development in our times of urban neoliberalization. This branch of literature focuses on the problematic relationship between market-oriented growth on the one hand and aspects of equality and justice on the other hand, which come along with the idea of sustainability. This article argues that the professionalization and new forms of urban management, as well as a shift towards urban governance and citizens’ participation have intensified consensual practices of urban regulation. Sustainable politics that have occurred in many cities around the world place emphasis on justice, tolerance and participation as the principal drivers for urban development. Empirical evidence shows, however, that these goals are subjugated to economic growth. Drawing on empirical work carried out in Freiburg, Germany – a city long hailed as a forerunner of urban sustainable development – this article promotes the opinion that the idea of ‘sustainable development’ in its current form is nothing more than an oxymoron, aimed and invented as a fuzzy concept in order to disguise the fundamentalist believe in growth that lies beyond such development.

    2014-12-01

    Lack of adequate safe water, the pollution of the aquatic environment and the mismanagement of resources are major causes of ill-health and mortality, particularly in the developing countries. In order to accommodate more growth, sustainable fresh water resource management will need to be included in future development plans. One of the major environmental issues of concern to policy-makers is the increased vulnerability of ground water quality. The main challenge for the sustainability of water resources is the control of water pollution. To understand the sustainability of the water resources, one needs to understand the impact of future land use and climate changes on the natural resources. Providing safe water and basic sanitation to meet the Millennium Development Goals will require substantial economic resources, sustainable technological solutions and courageous political will. A balanced approach to water resources exploitation for development, on the one hand, and controls for the protection of health, on the other, is required if the benefits of both are to be realized without avoidable detrimental effects manifesting themselves. Meeting the millennium development goals for water and sanitation in the next decade will require substantial economic resources, sustainable technological solutions and courageous political will. In addition to providing "improved" water and "basic" sanitation services, we must ensure that these services provide: safe drinking water, adequate quantities of water for health, hygiene, agriculture and development and sustainable sanitation approaches to protect health and the environment.

    Full Text Available The quality of public finance (QPF is a multidimensional concept. It may be regarded asrepresenting all the arrangements and operations regarding the financial politics that sustainthe macroeconomic objectives, particularly the long-term economic growth. Financialpolicies at European level highlight the fact that a concentration of the public expenses inareas that stimulate the economic growth and a more efficient use of the public resourcesare key methods for sustaining the economic growth. The empirical proofs seem to supportthe assumption according to which certain types of public expenses can supply incentivesand other can negatively influence the economic growth. The role of governments shouldalso be related to social security sustainability and also to public pensions sustainability.There is a growing literature which supports the pension reform as a solution for the latestdemographic trends. Some recent analyses though, outlined the negative influence of thefinancial crisis on the promised returns of private pension funds. The authors make apersonal analysis, taking into consideration both point of views.

    Full Text Available Angela Mariani,1 Antonella Vastola2 1Department of Economic and Legal Studies, University Parthenope, Naples, 2School of Agricultural, Forestry, Food and Environmental Sciences, University of Basilicata, Potenza, Italy Abstract: The winegrowing sector worldwide is strongly committed to improving environmental and social sustainability. The aim of this work, based on a literature review, is to highlight current sustainability perspectives and the related main issues. There is a broad consensus that the challenge to achieve a greater spread of sustainable practices is to enhance environmental and social sustainability while maintaining economic viability. From the producers' point of view, the priority is to bridge the still substantial knowledge gaps in terms of perceived environmental benefits, economic benefits, and costs. Thus, an increased research effort focusing on the costs and benefits of different winegrowing practices and technical assistance with implementation might support their diffusion. Moreover, targeted marketing strategies are needed to: enhance consumers' involvement and their attitude toward sustainable wine; improve understanding and use of sustainable labels and claims; and raise awareness of some environmental credentials of wine packaging, mainly with reference to lightweight glass bottles.

    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.

ISF Academy is a private Chinese bilingual school in Hong Kong serving over 1500 students K-12, following the framework and curriculum of the International Baccalaureate Organization (IBO). The strategy behind the implementation of this policy includes: development of a scientific sustainable curriculum that is age appropriate; establish a culture of sustainability within the ISF community and beyond to the wider HK community; install sustainable infrastructure that allows students to learn; and learn first hand sustainable living practices. It is well understood that solutions to the environmental challenges facing Hong Kong and our planet will require multiple disciplines. The current sustainability programs at ISF include: a) a whole school aerobic food waste composting system and organic farming, b) energy consumption monitoring of existing buildings, c) upcoming installation of an air pollution monitoring equipment that will correlate with the AQHI data collected by the Hong Kong government, d) a Renewable Energy Education Center (REEC) that will teach students about RE and also produce solar energy for classroom consumption, and e) student lead environmental group that manages the paper and used cooking oil recycling on campus. The Shuyuan Science and Sustainability faculty work closely with classroom teachers to ensure that the above mentioned projects are incorporated into the curriculum throughout the school. Interdisciplinary units (IDU) of study are being developed that encourage faculty and students to work across subject areas. Projects include Personal Projects, Extended Essays

    Full Text Available Sustainable use of the planet is based on the assumption that humankind can maintain conditions suitable for inhabiting the planet indefinitely. No robust evidence supports this assumption nor rejects it, and adequate evidence on this issue may not be available for centuries. Numeracy is the ability to use or understand numerical techniques of mathematics. Even if adequate numerical data were available, the important decisions humankind makes regarding sustainable use of the planet should not be guided by numerical information alone, such as economic numbers, but by eco- and sustainability ethics, which provides a values framework that indicates how the numbers should be used and interpreted.

    The EARTH (Education and Research: Testing Hypotheses) workshop has been active since 2002 (www.mbari.org/EARTH) and has been delivered at a wide variety of locations around the United States due in large part to the ability to attract co-hosts that have found value in this workshop model and are willing to host and help cover some of the costs. I would like to briefly introduce the workshop model but will spend most of the presentation on Satellite EARTH workshops which are organized and run by EARTH educators. This includes finding participants (educators and researchers) as well as all of the logistics involved in running a Professional Development workshop. MBARI (Monterey Bay Aquarium Research Institute) is able to provide some limited funding for educator stipends, food, and supplies. These satellite workshops help disseminate the EARTH model and provide a very cost-effective method for sustaining EARTH, getting data into the classrooms, and making connections between researchers and educators.

  12. Sustainable supply chain management: current debate and future directions

    Directory of Open Access Journals (Sweden)

    Bruno Silvestre

    Full Text Available Abstract This paper is a research brief on sustainable supply chain management and covers some of the key elements of literature’s past debate and trends for future directions. It highlights the growth of this research area and reinforces the importance of a full consideration of all three key dimensions of sustainability when managing sustainable supply chains, i.e., the financial, environmental and social dimensions. Therefore, supply chain decision makers need to unequivocally assess the impact of their decisions on the financial, environmental and social performances of their supply chains. This paper also argues that risks and opportunities are the key drivers for supply chain decision makers to adopt sustainability within their operations, and that barriers to sustainability adoption exist. This research highlights that, depending on the focus adopted, supply chains can evolve and shift from more traditional to more sustainable approaches over time. The paper concludes with some promising avenues for future investigation.

  13. Cooperative retraction of bundled type IV pili enables nanonewton force generation.

    Directory of Open Access Journals (Sweden)

    Nicolas Biais

    2008-04-01

    Full Text Available The causative agent of gonorrhea, Neisseria gonorrhoeae, bears retractable filamentous appendages called type IV pili (Tfp. Tfp are used by many pathogenic and nonpathogenic bacteria to carry out a number of vital functions, including DNA uptake, twitching motility (crawling over surfaces, and attachment to host cells. In N. gonorrhoeae, Tfp binding to epithelial cells and the mechanical forces associated with this binding stimulate signaling cascades and gene expression that enhance infection. Retraction of a single Tfp filament generates forces of 50-100 piconewtons, but nothing is known, thus far, on the retraction force ability of multiple Tfp filaments, even though each bacterium expresses multiple Tfp and multiple bacteria interact during infection. We designed a micropillar assay system to measure Tfp retraction forces. This system consists of an array of force sensors made of elastic pillars that allow quantification of retraction forces from adherent N. gonorrhoeae bacteria. Electron microscopy and fluorescence microscopy were used in combination with this novel assay to assess the structures of Tfp. We show that Tfp can form bundles, which contain up to 8-10 Tfp filaments, that act as coordinated retractable units with forces up to 10 times greater than single filament retraction forces. Furthermore, single filament retraction forces are transient, whereas bundled filaments produce retraction forces that can be sustained. Alterations of noncovalent protein-protein interactions between Tfp can inhibit both bundle formation and high-amplitude retraction forces. Retraction forces build over time through the recruitment and bundling of multiple Tfp that pull cooperatively to generate forces in the nanonewton range. We propose that Tfp retraction can be synchronized through bundling, that Tfp bundle retraction can generate forces in the nanonewton range in vivo, and that such high forces could affect infection.

    The importance and role of the geosciences in studies of sustainable agriculture include such traditional research areas as, agromineral resource assessments, the mapping and classification of soils and soil amendments, and the evaluation of landscapes for their vulnerability to physical and chemical degradation. Less traditional areas of study, that are increasing in societal importance because of environmental concerns and research into sustainable systems in general, include regional geochemical studies of plant and animal trace element deficiencies and toxicities, broad-scale water quality investigations, agricultural chemicals and the hydrogeologic interface, and minimally processed and ion-exchange agrominerals. We discuss the importance and future of phosphate in the US and world based on human population growth, projected agromineral demands in general, and the unavailability of new, high-quality agricultural lands. We also present examples of studies that relate geochemistry and the hydrogeologic characteristics of a region to the bioavailability and cycling of trace elements important to sustainable agricultural systems. ?? 1993.

Therefore the authors start with a definition which is stable to serve as an anchor for further research as well as for discussions among scientists, managers and politicians, ideally across different disciplines. The character of this book is purely conceptual. The argumentation is based on comparison of new and demanding requisites with existing models (process and network architectures in the field of logistics). Formerly neglected impacts on the environment will be included. Main features of a new approach will be developed which are capable to avoid these impacts and to align logistics with the requirements of sustainability. In order to make logistics sustainable large parts will have to be reinvented. The focus needs to be on decoupling transportation activities from economic growth rates.

  18. Sovereignty, individuality, and sustainability

    Full Text Available Humans must acknowledge that the biosphere is the essential support for all living organisms. In order to achieve sustainable use of the planet, humans must proceed beyond egocentrism, ethnocentrism, homocentrism, and biocentrism to ecocentrism. National states, with present policies, are a major obstacle to sustainable use of the planet. However, there is some evidence that the individual has increasing sovereignty at the expense of both nation states and the environment. Still, the primary obstacle to sustainability is inherent in the present system of sovereign nation states. The basic question is how much sovereignty must nation-states and individuals relinquish to preserve the health of Earth's biospheric life support system. A free and open exchange of thoughts on this subject is long overdue. To acheive sustainable use of the planet, humankind must view its identity within the context of the interdependent web of life.
