    The environment problems on global scale have been highlighted in addition to the local problems due to the rapid increase of population, the increase of energy demand and so on. The global environment summit was held in Brazil. Now, global environment problems are the problems for mankind, and their importance seems to increase toward 21st century. In such circumstances, cogeneration can reduce carbon dioxide emission in addition to energy conservation, therefore, attention has been paid as the countermeasure for global environment. The background of global environment problems is explained. As to the effectiveness of cogeneration for global environment, the suitability of city gas to environment, energy conservation, the reduction of carbon dioxide and nitrogen oxides emission are discussed. As for the state of spread of cogeneration, as of March, 1992, those of 2250 MW in terms of power generation capacity have been installed in Japan. It is forecast that cogeneration will increase hereafter. As the future systems of cogeneration, city and industry energy center conception, industrial repowering, multiple house cogeneration and fuel cells are described. (K.I.)

    In recent years two trends have come into conflict in the international arena. The first is the globalization of economy and the second is the increased public concern over the environmental impact of economic activities and awareness of the global dimensions of many environmental problems. Nowadays confrontation of the issue of globalization and economic liberalization and protect of the environment is a matter of heated debate and environmentalists see globalization posing a threat to environment standards. The effects of liberalization on environment in the developing world have been analyzed from the perspective of the pollution- have hypothesis. The hypothesis suggests that the liberalization encourages a spatial displacement of the so-called d irty o r pollution- intensive industries from the developed countries with stricter environmental regulations to their preferential location in developing countries which enjoy minimal environmental regulations or capacity for environmental monitoring and enforcement. It also suggests that economic policies which promote foreign investment in the natural resources of developing countries will increase rates of natural-resource extraction in the developing world. according to the theory, the translational firms will employ cheep technologies in developing countries which are not environmental sound and no longer permitted to use in the industrialized world

    The development of the Third World and the protection of the environment are two major global problems interconnected by energy - the motor of economic growth and the main cause of deterioration of the global environment. They can no longer be separated. The threats of ozone, acid rain, and global warming are global in scope and solutions must involve energy consumption, conservations, and renewable resources. The precept that development should hinge on sound management of natural resources and the environment no longer has merely local or regional significance. It is a global concern and each person should feel a sense of ethical commitment as a world citizen

    In many areas, the word most often used to describe Japanese policy is open-quotes enigma.close quotes In some ways, Japan's record on environmental policy also has elements of mystery and contradiction. On the one hand, Japan's history and culture often are associated with a reverence for nature. Indeed, Japan does lead the world in certain environmental areas, such as reduction of conventional air pollutants and compensation of air pollution victims. On the other hand, Japan has been widely criticized for its poor record in preserving its domestic environment, contribution to tropical deforestation, and unwillingness to protect endangered species. Today, the international community clamors for Japan to take its share of responsibility, as an economic superpower, for the global environment. To secure its place in world affairs, Japan slowly has begun to respond to this pressure on issues ranging from ivory importation to reduction of CFC emissions. There is some hope that the government's particular willingness to address global warming may be a sign of significant changes to come in Japanese environmental policy. However, international pressure remains on the many environmental issues Japan has yet to resolve, including tropical deforestation and financing of Third World development projects that harm the environment. Japan's environmental policy is most effective when government and industry cooperate to find technical solutions to environmental problems. Although in recent years Japan's energy consumption has risen sharply, the Japanese have developed numerous technologies to reduce pollution and increase economic growth by improving energy efficiency. It is in these technologies that Japan has made the greatest strides and has the most to offer the global environment

    It has been well known that the global environment of the earth is basically determined by the radiation equilibrium of the earth atmosphere system embedded in the solar radiation. However, the surface temperature of about 15 degC on average is much higher than that determined by the radiation equilibrium. This is due to the so-called greenhouse gases in the atmosphere such as carbon dioxide, water vapor, methane and others. Also the global environment has evolved by interacting with the living things on the earth, for example, tree oxygen by photosynthesis, and a small amount of ozone protecting living things from the fetal damage due to solar ultraviolet radiation. The solar radiation of short wavelength, that is, ultraviolet to X-ray influences atmospheric constituents, and the thermal structure and dynamics of the atmosphere through chemical reaction. The solar energetic particles produced by solar flares precipitate in the polar regions, and the nitric oxides are produced by auroral X-ray. Auroral activities accelerate particles in the magnetosphere. All these radiations cause significant global changes. Human activities increase greenhouse gases rapidly and cause global warming, and atmospheric chloro-fluoro-carbon (CFC) makes the ozone hole. Now, human activities must be modified to match the natural cycle of materials. (K.I.)

    Full Text Available Inabilities to deal with the changing environment may lead Higher Education Institutions (HEI to loose institutional attractiveness. Digital transformation requires global insertion as essential feature to institutional attractiveness. Processes for international education seem to lack the links between real environmental trends and the internal capabilities to global education. HEI managers may approach endeavors to internationalize education combining ambidextrous strategy supported by consolidated resilience capabilities. The latest ones refer to building internal value attributes to increase institutional attractiveness assuring solid standing in the global environment. In this article, a theoretical essay, we approach the problem of creating resilience as a way of backing up ambidexterity to generate institutional attractiveness. The set of value attributes, on the other hand, may originate strategic routes to strengthen internal competences and to make the institution more attractive, as a dynamic capability.

  14. Global warming without global mean precipitation increase?

    Science.gov (United States)

    Salzmann, Marc

    2016-06-01

    Global climate models simulate a robust increase of global mean precipitation of about 1.5 to 2% per kelvin surface warming in response to greenhouse gas (GHG) forcing. Here, it is shown that the sensitivity to aerosol cooling is robust as well, albeit roughly twice as large. This larger sensitivity is consistent with energy budget arguments. At the same time, it is still considerably lower than the 6.5 to 7% K(-1) decrease of the water vapor concentration with cooling from anthropogenic aerosol because the water vapor radiative feedback lowers the hydrological sensitivity to anthropogenic forcings. When GHG and aerosol forcings are combined, the climate models with a realistic 20th century warming indicate that the global mean precipitation increase due to GHG warming has, until recently, been completely masked by aerosol drying. This explains the apparent lack of sensitivity of the global mean precipitation to the net global warming recently found in observations. As the importance of GHG warming increases in the future, a clear signal will emerge.

    The current state of Japanese science and technology policy is discussed within the framework of overall global environmental policy. Principles of Japanese environmental policy include participation in international schemes for conservation of the global environment, promotion of Japanese research on the global environment, development and diffusion of technologies contributing to conservation of the global environment, contribution to conservation of the environment in developing countries, and maintenance of economic and social activities in Japan at an environmentally beneficial level. The Japanese environmental budget includes expenditures for earth observation and monitoring by satellite, energy-related research and development, and control of greenhouse gas emissions. The proportion of overall Japanese research and development (R ampersand D) expenditures which were spent on the global environment was about 2% in 1991. Of governmental research expenditures, ca 22% involve the global environment; however, some part of the expenditures on energy R ampersand D and on earth observation satellite R ampersand D are also environment-related. 5 figs

Every ecosystem shows signs of damage: growing quantities of wastes; decreasing water supplies; soil degradation; coastal zone deterioration; deforestation and climatic change; global warming due to ozone depletion. Solutions must involve a cooperative and holistic global effort in three areas: scientific understanding of how the interactive physical, chemical and biological processes regulate the total Earth system; public policy implications including closer liaison between scientists and policymakers;and understanding of the state of the global environment, what is going wrong, why, and whether it is getting worse

    Full Text Available The article discusses the issue of the global marketing environment in line with the factors determining its external conditions. The aim is to specify the marketing-environment indicators in the international context and interpret the use of geographical maps illustratively documenting the differences of particular parameters in various parts of the global market. The research-results help update the theoretical framework of global environment factors. These data are also important for practice. Many enterprises consider the question of optimising their sources and directing their goals towards the opportunities available thanks to global markets. The global environment mapping is thereby an important basis for the marketing activities whose implementation across national boundaries is going to be mainly influenced by peculiarities of the environment involving foreign markets and their changes.

It has become an important subject to make the preservation of global environment and durable economical development compatible by effectively utilizing limited resources and energy. The electric power companies have advanced positively the prevention of pollution and the preservation of environment, and attained the environment preservation of top level in the world. The consciousness of people on environmental problems has heightened, therefore the construction and operation of power plants harmonized to districts are important. The countermeasures to environmental problems taken by electric power companies are reported. (K.I.)

    Lysergic acid diethylamide (LSD) is a non-selective serotonin-receptor agonist that was first synthesized in 1938 and identified as (potently) psychoactive in 1943. Psychedelics have been used by indigenous cultures for millennia [1]; however, because of LSD's unique potency and the timing of its discovery (coinciding with a period of major discovery in psychopharmacology), it is generally regarded as the quintessential contemporary psychedelic [2]. LSD has profound modulatory effects on consciousness and was used extensively in psychological research and psychiatric practice in the 1950s and 1960s [3]. In spite of this, however, there have been no modern human imaging studies of its acute effects on the brain. Here we studied the effects of LSD on intrinsic functional connectivity within the human brain using fMRI. High-level association cortices (partially overlapping with the default-mode, salience, and frontoparietal attention networks) and the thalamus showed increased global connectivity under the drug. The cortical areas showing increased global connectivity overlapped significantly with a map of serotonin 2A (5-HT2A) receptor densities (the key site of action of psychedelic drugs [4]). LSD also increased global integration by inflating the level of communication between normally distinct brain networks. The increase in global connectivity observed under LSD correlated with subjective reports of "ego dissolution." The present results provide the first evidence that LSD selectively expands global connectivity in the brain, compromising the brain's modular and "rich-club" organization and, simultaneously, the perceptual boundaries between the self and the environment.

    The simultaneous increases in obesity in almost all countries seem to be driven mainly by changes in the global food system, which is producing more processed, affordable, and effectively marketed food than ever before. This passive overconsumption of energy leading to obesity is a predictable outcome of market economies predicated on consumption-based growth. The global food system drivers interact with local environmental factors to create a wide variation in obesity prevalence between populations. Within populations, the interactions between environmental and individual factors, including genetic makeup, explain variability in body size between individuals. However, even with this individual variation, the epidemic has predictable patterns in subpopulations. In low-income countries, obesity mostly affects middle-aged adults (especially women) from wealthy, urban environments; whereas in high-income countries it affects both sexes and all ages, but is disproportionately greater in disadvantaged groups. Unlike other major causes of preventable death and disability, such as tobacco use, injuries, and infectious diseases, there are no exemplar populations in which the obesity epidemic has been reversed by public health measures. This absence increases the urgency for evidence-creating policy action, with a priority on reduction of the supply-side drivers. Copyright © 2011 Elsevier Ltd. All rights reserved.

    A large number of assessments of regional marine areas have been conducted in recent years for a variety of purposes. Periodic reviews of the state of the marine environment have been undertaken by the United Nations Joint Group of Experts on the Scientific Aspects of Marine Environmental Protection (GESAMP). The most recent of these global assessments was published in 1990. The international adoption of a Global Programme of Action for the Protection of the Marine Environment from Land-Based Activities in 1995 has led to additional demand for regional assessments and a global review. The regional assessments are either completed or in train largely through mechanisms associated with the UNEP Regional Seas Programme. The global assessment has been assigned to GESAMP and incorporated into its plans for the preparation of a new global review to be completed in the year 2002. The Intergovernmental Oceanographic Commission, (IOC) the Scientific Committee for Oceanic Research (SCOR) and the Scientific Committee on Problems of the Environment (SCOPE) are collaborating in a review of ocean science. The Global Environment Facility (GEF) recently approved funding for a 'Global International Waters Assessment' (GIWA) partly as a means of determining priorities within its International Waters Portfolio.

  11. Increasing women in leadership in global health.

    Science.gov (United States)

    Downs, Jennifer A; Reif, Lindsey K; Hokororo, Adolfine; Fitzgerald, Daniel W

    2014-08-01

    Globally, women experience a disproportionate burden of disease and death due to inequities in access to basic health care, nutrition, and education. In the face of this disparity, it is striking that leadership in the field of global health is highly skewed towards men and that global health organizations neglect the issue of gender equality in their own leadership. Randomized trials demonstrate that women in leadership positions in governmental organizations implement different policies than men and that these policies are more supportive of women and children. Other studies show that proactive interventions to increase the proportion of women in leadership positions within businesses or government can be successful. Therefore, the authors assert that increasing female leadership in global health is both feasible and a fundamental step towards addressing the problem of women's health. In this Perspective, the authors contrast the high proportion of young female trainees who are interested in academic global health early in their careers with the low numbers of women successfully rising to global health leadership roles. The authors subsequently explore reasons for female attrition from the field of global health and offer practical strategies for closing the gender gap in global health leadership. The authors propose solutions aimed to promote female leaders from both resource-wealthy and resource-poor countries, including leadership training grants, mentorship from female leaders in global professions, strengthening health education in resource-poor countries, research-enabling grants, and altering institutional policies to support women choosing a global health career path.

  12. Terrestrial Feedbacks Incorporated in Global Vegetation Models through Observed Trait-Environment Responses

    Science.gov (United States)

    Bodegom, P. V.

    2015-12-01

    Most global vegetation models used to evaluate climate change impacts rely on plant functional types to describe vegetation responses to environmental stresses. In a traditional set-up in which vegetation characteristics are considered constant within a vegetation type, the possibility to implement and infer feedback mechanisms are limited as feedback mechanisms will likely involve a changing expression of community trait values. Based on community assembly concepts, we implemented functional trait-environment relationships into a global dynamic vegetation model to quantitatively assess this feature. For the current climate, a different global vegetation distribution was calculated with and without the inclusion of trait variation, emphasizing the importance of feedbacks -in interaction with competitive processes- for the prevailing global patterns. These trait-environmental responses do, however, not necessarily imply adaptive responses of vegetation to changing conditions and may locally lead to a faster turnover in vegetation upon climate change. Indeed, when running climate projections, simulations with trait variation did not yield a more stable or resilient vegetation than those without. Through the different feedback expressions, global and regional carbon and water fluxes were -however- strongly altered. At a global scale, model projections suggest an increased productivity and hence an increased carbon sink in the next decades to come, when including trait variation. However, by the end of the century, a reduced carbon sink is projected. This effect is due to a downregulation of photosynthesis rates, particularly in the tropical regions, even when accounting for CO2-fertilization effects. Altogether, the various global model simulations suggest the critical importance of including vegetation functional responses to changing environmental conditions to grasp terrestrial feedback mechanisms at global scales in the light of climate change.

    1997-01-01

    Integrated assessments in support of environmental policy have been applied to a number of countries and regions, and to international negotiations. UNEP's first Global Environment Outlook (GEO-1) can be seen as a step towards making the tool of integrated assessment more widely available as a means for focusing action. This technical report documents RIVM's contribution to the GEO-1 report, focusing on the subject 'looking ahead'. It is illustrated that a 'what if' analysis helps to look beyond the delays in environmental and resource processes. This report illustrates that integrated assessment and modelling techniques can be excellent tools for environment and development policy-setting. The methodology, however, will need to be further developed and adapted to the realities and expectations of diverse regions, incorporating alternative policy strategies and development scenarios. This report focuses primarily on the period 1970-2015, because reliable historical data are often only generally available from 1970 onwards and the year 2015 is believed to match the time perspective of decision-makers. The findings of the analysis are reported in terms of six regions, corresponding with the division of the UNEP regional offices. Questions asked are: how will socioeconomic driving forces affect freshwater and land resources, and how will these changes mutually interact, and why are these changes important for society? Chapter 2 deals with the development of the social and economic driving forces. In the Chapters 3 and 4 it is discussed how this pressure influences selected aspects of the environment. Chapter 3 alone addresses the importance of selected elements of the interacting global element cycles for environmental quality, while Chapter 4 addresses land resources, their potential for food production and associated dependence on freshwater resources.

    As the offshore industry continues to develop and move into increasingly deeper waters, technological boundaries are being pushed to new limits. Along with these advances, the design, fabrication and installation of deepwater oil and gas projects has become an increasingly global endeavor. After providing an overview of the history and role of Classification Societies, this paper reviews the challenges of securing classification and regulatory approval in a global environment. Operational, procedural and technological changes which one Classification Society; the American Bureau of Shipping, known as ABS, has implemented to address these challenges are presented. The result of the changes has been a more customized service aiming at faster and more streamlined classification approval process. (author)

    Development of an innovative, integrated, automated system (Global Positioning Site Environment Evaluator - GPSEETM) for surveying contaminated waste sites is described. This system makes novel use of the Global Positioning System (GPS) satellite constellation for establishing specific locations and current times for surveying radioactive, hazardous, or mixed-waste sites. GPSEE may also be used for waste site contamination surveys after remediation activities to ensure environmental remediation is complete. A base station is established for collecting and recording data and directing field operations for field stations which may be located many miles from the base station. The field operators collect site surveying and contamination data utilizing a variety of chemical and radiological sensors. A major goal for the data collection process is to collect all data utilizing in situ sensors, thereby minimizing the need for collecting soil and water samples. Site contamination data is transmitted electronically to the base station for recording and processing. The GPSEE system is being developed for use at DOE/DOD and a variety of industrial facilities. 3 figs

    The rising importance of the BASIC countries in a changing world Over the last decade the emerging economies have become increasingly important for the development of the global economy. This trend was reinforced by the global financial crisis which hit the developed economies the hardest, and after which the emerging economies emerged as crucial growth centres in the global economy. We are entering into a new era in global politics, and a broad process is currently taking place of restructuring global institutions and political processes to increasingly take into account the interests of the emerging economies. A global environmental crisis constitutes the backdrop for this change in global politics, as the current volume of production and consumption of the planets renewable resources (including the capacity to absorb greenhouse gas emissions) is beyond the planets regenerative capacity. The breakdown of the Doha Development Round in World Trade, the creation of the BRIC group and the G20, the emergence of the BASIC group of key emerging economies and the following developments under the UN Framework Convention on Climate Change, all testify to the fact that China, India, South Africa and Brazil (BASIC) today have a decisive and increasing influence in world politics. With regards to the environment, this means that BASIC countries increasingly will set environmental standards in global markets as their economies to a greater extent come to represent global buying power, increasingly will influence to what extent environmental concerns are mainstreamed into international agreements (such as WTO) in general, and also will decide the scope and level of ambition and scope of international environmental agreements (as we see in UNFCCC). Among the emerging economies China, India, South Africa, and Brazil stand out as particularly important. China and India alone represent more than 35 per cent of the global population and are the most rapidly growing economies in the

    1991-01-01

    The present status of investigation of acid rain, stratospheric ozone depletion and greenhouse effect and their relations to radiation exposure are reported. Soil acidification increases transfer rates of radioactivities to plants which increases the population dose. There are two types of ozone depletion, conventional type and ozone hole type and the latter is much more serious than the former. In the greenhouse effect, although there are large uncertainties both in theoretical and observational sides, present predictions about the global warming will not be very far from reality. Environmental effects are wide-ranging and serious. Radon and thoron exhalation rates are affected by the global warming. The influence of the greenhouse effect on ozone depletion is to suppress depletion for conventional type and enhance depletion for ozone hole type. (author) 65 refs

    The Applied Pharmaceutical Software Meeting is held annually. It is sponsored by The Boston Society, a not-for-profit organization that coordinates a series of meetings within the global pharmaceutical industry. The meeting generally focuses on laboratory applications, but in recent years has expanded to include some software applications for clinical trials. The 2011 meeting emphasized the global laboratory environment. Global clinical trials generate massive amounts of data in many locations that must be centralized and processed for efficient analysis. Thus, the meeting had a strong focus on establishing networks and systems for dealing with the computer infrastructure to support such environments. In addition to the globally installed laboratory information management system, electronic laboratory notebook and other traditional laboratory applications, cloud computing is quickly becoming the answer to provide efficient, inexpensive options for managing the large volumes of data and computing power, and thus it served as a central theme for the meeting.

    2015-01-01

    Today, blueberries are recognized worldwide as one of the foremost health foods, becoming one of the crops with the highest productive and commercial projections. Over the last 100 years, the geographical area where highbush blueberries are grown has extended dramatically into hotter and drier environments. The expansion of highbush blueberry growing into warmer regions will be challenged in the future by increases in average global temperature and extreme fluctuations in temperature and rainfall patterns. Considerable genetic variability exists within the blueberry gene pool that breeders can use to meet these challenges, but traditional selection techniques can be slow and inefficient and the precise adaptations of genotypes often remain hidden. Marker assisted breeding (MAB) and phenomics could aid greatly in identifying those individuals carrying adventitious traits, increasing selection efficiency and shortening the rate of cultivar release. While phenomics have begun to be used in the breeding of grain crops in the last 10 years, their use in fruit breeding programs it is almost non-existent. PMID:26483803

    Determine trends in global health-related publication in otolaryngology. A review of research databases. A search of publications available on PubMed and nine additional databases was undertaken reviewing two time periods 10 years apart for the timeframes 1998 to 2002 (early time period) and 2008 to 2012 (recent time period) using specific search terms to identify global health-related publications in otolaryngology. Publications were examined for region of origin, subspecialty, type of publication, and evidence of international collaboration. χ and t test analyses were used to identify trends. In the 1998 to 2002 time period, a total of 26 publications met inclusion criteria for the study, with a mean of 5.2 ± 2.8 publications per year. In the 2008 to 2012 time period, a total of 61 publications met inclusion criteria, with a mean of 12.3 ± 5.6 publications per year. The 235% increase in global health-related publications identified between the two study periods was statistically significant (P = .02). The absolute number of publications in which collaboration occurred between countries increased from three in the early time period to nine the recent time period. There has been a significant increase in the volume of global health-related publications in English language otolaryngology journals over the past decade, providing strong evidence of the increasing trend of global health as an academic pursuit within the field of otolaryngology. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

    1996-12-31

    The global climate change caused by greenhouse gases (GHGs) emission has received wide attention from all countries in the world. Global environmental protection as a common problem has confronted the human being. As a main component of coalbed methane, methane is an important factor influencing the production safety of coal mine and threatens the lives of miners. The recent research on environment science shows that methane is a very harmful GHG. Although methane gas has very little proportion in the GHGs emission and its stayed period is also very short, it has very obvious impact on the climate change. From the estimation, methane emission in the coal-mining process is only 10% of the total emission from human`s activities. As a clean energy, Methane has mature recovery technique before, during and after the process of mining. Thus, coalbed methane is the sole GHG generated in the human`s activities and being possible to be reclaimed and utilized. Compared with the global greenhouse effect of other GHGs emission abatement, coalbed methane emission abatement can be done in very low cost with many other benefits: (1) to protect global environment; (2) to improve obviously the safety of coal mine; and (3) to obtain a new kind of clean energy. Coal is the main energy in China, and coalbed contains very rich methane. According to the exploration result in recent years, about 30000{approximately}35000 billion m{sup 2} methane is contained in the coalbed below 2000 m in depth. China has formed a good development base in the field of reclamation and utilization of coalbed methane. The author hopes that wider international technical exchange and cooperation in the field will be carried out.

  15. Global Indicators Analysis and Consultancy Experience Insights into Correlation between Entrepreneurial Activities and Business Environment

    Directory of Open Access Journals (Sweden)

    Jovan Krivokapić

    2015-02-01

    Full Text Available Many researches and practical experiences clearly indicate the existence of a strong relationship between entrepreneurial activities and the business environment in which these activities are initiated. Although this topic has been quite ignored until the late twentieth century, a lot of studies and consulting practice have contributed to the fact that there are now a number of theories concerning mentioned correlation. These theories aim to offer a model that would provide better utilization of the possibilities from the business environment which could be very important for the development from both macroeconomic and microeconomic aspects. An increasing number of articles on this topic says enough about its importance, and numerous researches by many reputable globally recognized institutions go in favor of this claim. There are many indicators that observe the economic situation in a country or a region from different aspects, so the analyses of these indicators make it possible to determine the specific relationships between entrepreneurial activities and the local and the global business environment. Given the complexity of these relations, the impact cannot be observed partially, without taking into consideration other important factors, but more detailed analyses, however, result in some useful conclusions, which in the proper context can have a positive impact on many economic factors. It is very important to emphasize the fact that the correlation between the business environment and entrepreneurial activities is bidirectional, since this influence is mutual, so that changes in one of these factors can and usually cause some modifications in the other. Frequent series of such iterations actually lead to changes in the business environment, while entrepreneurial activity changes its shape and affects the economy of a country or a region, which is of particular importance for its competitiveness in the era of globalization.

    1991-01-01

    At present about 90% of the world's energy consumption is met by the fossil carbon fuel used in the form of coal, oil and natural gas. This results into release of vast amounts of waste gas CO 2 into the atmosphere posing a threat to the global environment. Moreover this energy source is not sustainable (renewable) and its use amounts to spending Earth's capital resources. The options to this energy source are biomass energy, hydro power, solar energy, geothermal energy and nuclear energy. The potentials, limitations, geological impact and environmental dangers, if any, of these sources are discussed in brief. Energy conservation through energy efficient systems is also one more option. Problems and potential for change to sustainable energy systems with respect to India and Canada are examined. Finally it is pointed out that the ultimate solution to the world's energy problem lies in population control and population reduction. This will make possible for the world to have a sustainable energy system primarily based on solar energy. (M.G.B.). 15 refs

  17. Change in ocean subsurface environment to suppress tropical cyclone intensification under global warming

    Science.gov (United States)

    Huang, Ping; Lin, I. -I; Chou, Chia; Huang, Rong-Hui

    2015-01-01

    Tropical cyclones (TCs) are hazardous natural disasters. Because TC intensification is significantly controlled by atmosphere and ocean environments, changes in these environments may cause changes in TC intensity. Changes in surface and subsurface ocean conditions can both influence a TC's intensification. Regarding global warming, minimal exploration of the subsurface ocean has been undertaken. Here we investigate future subsurface ocean environment changes projected by 22 state-of-the-art climate models and suggest a suppressive effect of subsurface oceans on the intensification of future TCs. Under global warming, the subsurface vertical temperature profile can be sharpened in important TC regions, which may contribute to a stronger ocean coupling (cooling) effect during the intensification of future TCs. Regarding a TC, future subsurface ocean environments may be more suppressive than the existing subsurface ocean environments. This suppressive effect is not spatially uniform and may be weak in certain local areas. PMID:25982028

    Kunkel, Matthew; McGuire, Melissa; Smith, David A.; Gefert, Leon P.

    2011-01-01

    The GLobal Integrated Design Environment (GLIDE) is a collaborative engineering application built to resolve the design session issues of real-time passing of data between multiple discipline experts in a collaborative environment. Utilizing Web protocols and multiple programming languages, GLIDE allows engineers to use the applications to which they are accustomed in this case, Excel to send and receive datasets via the Internet to a database-driven Web server. Traditionally, a collaborative design session consists of one or more engineers representing each discipline meeting together in a single location. The discipline leads exchange parameters and iterate through their respective processes to converge on an acceptable dataset. In cases in which the engineers are unable to meet, their parameters are passed via e-mail, telephone, facsimile, or even postal mail. The result of this slow process of data exchange would elongate a design session to weeks or even months. While the iterative process remains in place, software can now exchange parameters securely and efficiently, while at the same time allowing for much more information about a design session to be made available. GLIDE is written in a compilation of several programming languages, including REALbasic, PHP, and Microsoft Visual Basic. GLIDE client installers are available to download for both Microsoft Windows and Macintosh systems. The GLIDE client software is compatible with Microsoft Excel 2000 or later on Windows systems, and with Microsoft Excel X or later on Macintosh systems. GLIDE follows the Client-Server paradigm, transferring encrypted and compressed data via standard Web protocols. Currently, the engineers use Excel as a front end to the GLIDE Client, as many of their custom tools run in Excel.

  1. Are Global Economic Losses from Natural Hazards Increasing?

    Science.gov (United States)

    McMullan, Caroline; Simic, Milan; Tosco, Antonello; Latchman, Shane

    2016-04-01

    Global society has long been influenced by natural hazards, but it has been widely noted that the economic cost of natural hazards has been rising rapidly over recent decades. This upward trend highlights the increasing exposure of the global economy to natural hazards and the need for society to understand the driving factors to help improve the resilience of communities. However disaster risk is driven by a plethora of factors, including population, wealth, land-use, and demographics. Consider also the natural variability in the frequency and severity of events, climate change, and implementation of resilience policies, and it becomes clear that disaster-risk management is a challenging field. To investigate the apparent upward trend in reported annual economic losses from natural disasters, socioeconomic factors known to influence the magnitude of losses must first be accounted for. Adjustment for these factors, known as loss normalisation, aims to estimate the losses sustained if historical events were to impact present day society. We have undertaken a detailed assessment of global economic losses from natural disasters for the period 1995 through 2013. Although the studied time-period is relatively short, expanding the investigated period would not necessarily produce more reliable insights owing to the inherent difficulty in obtaining accurate economic loss estimates for earlier periods and the challenge of finding consistent and reliable sources of socioeconomic data for the normalisation process. The results of the study, presented at a global and regional level, appear to suggest that the main driver of perceived increase in economic losses over the last ~20 years was the development of nations' economies (i.e. increase in population and wealth/GDP) and not in the natural hazards themselves. As populations all over the world migrate into areas of higher natural hazards regions (e.g. coastal areas or floodplain zones) and global wealth continues to

  2. Future Warming Increases Global Maize Yield Variability with Implications for Food Markets

    Science.gov (United States)

    2017-12-01

    If current trends in population growth and dietary shifts continue, the world will need to produce about 70% more food by 2050, while earth's climate is rapidly changing. Rising temperatures in particular are projected to negatively impact agricultural production, as the world's staple crops perform poorly in extreme heat. Theoretical models suggest that as temperatures rise above plants' optimal temperature for performance, not only will mean yields decline rapidly, but the variability of yields will increase, even as interannual variations in climate remain unchanged. Here we use global datasets of maize production and climate variability combined with CMIP5 temperature projections to quantify how yield variability will change in major maize producing countries under 2°C and 4°C of global warming. Maize is the world's most produced crop, and is linked to other staple crops through substitution in consumption and production. We find that in warmer climates - absent any breeding gains in heat tolerance - the Coefficient of Variation (CV) of maize yields increases almost everywhere, to values much larger than present-day. This increase in CV is due both to an increase in the standard deviation of yields, and a decrease in mean yields. In locations where crop failures become the norm under high (4°C) warming (mostly in tropical, low-yield environments), the standard deviation of yields ultimately decreases. The probability that in any given year the most productive areas in the top three maize producing countries (United States, China, Brazil) have simultaneous production losses greater than 10% is virtually zero under present-day climate conditions, but increases to 12% under 2°C warming, and 89% under 4°C warming. This has major implications for global food markets and staple crop prices, affecting especially the 2.5 billion people that comprise the world's poor, who already spend the majority of their disposable income on food and are particularly vulnerable

    2010-01-01

    The GLobal Integrated Design Environment (GLIDE) is a client-server software application purpose-built to mitigate issues associated with real time data sharing in concurrent engineering environments and to facilitate discipline-to-discipline interaction between multiple engineers and researchers. GLIDE is implemented in multiple programming languages utilizing standardized web protocols to enable secure parameter data sharing between engineers and researchers across the Internet in closed and/or widely distributed working environments. A well defined, HyperText Transfer Protocol (HTTP) based Application Programming Interface (API) to the GLIDE client/server environment enables users to interact with GLIDE, and each other, within common and familiar tools. One such common tool, Microsoft Excel (Microsoft Corporation), paired with its add-in API for GLIDE, is discussed in this paper. The top-level examples given demonstrate how this interface improves the efficiency of the design process of a concurrent engineering study while reducing potential errors associated with manually sharing information between study participants.

    1993-01-01

    A year after the environmental summit in Rio de Janeiro a turnabout in the alarming global environmental change is not within sight. Thoughtless economic activity and population growth threaten, damage or destroy many natural biospheres and biological communities world-wide. In the long term mankind is endangering its own survival. Global environmental changes have other causes and much more complex effects than most national environmental problems. In its first annual expertise of 1993, the scientific advisory council on ''Global Environmental Change'' describes the close global interknitting of man and nature, society and environment, in order to lay the foundation for future expertises. Global environmental targets and future economic development must be better matched to each other. In view of the following major trends: increase in world population, changing composition of the atmosphere in the long term, loss of biological variety and deterioration and loss of soils, the advisory committee gives some main recommendations: increase in German development aid to 1% of the GNP, rapid implementation of the climate convention, i.e., cuts in CO 2 emissions, and sensitization of citizens to global environmental problems as well as schemes for the promotion of environmentally-friendly practices.

    This report relates to the ongoing development of scenarios for the third Global Environment Outlook (GEO-3) of UNEP. It illustrates the scale and type of environmental impacts that GEO-3 needs to consider. It does so by quantifying impacts using existing, recent studies whose scenarios come closest to the current tentative global storylines for GEO-3. With a view to GEO-3;s envisaged role as input for the Rio+10 Earth Summit in 2002, this report suggests a focus for the GEO-3 scenario analys...

    Cognitive emotion regulation (CER) enables humans to flexibly modulate their emotions. While local theories of CER neurobiology suggest interactions between specialized local brain circuits underlying CER, e.g., in subparts of amygdala and medial prefrontal cortices (mPFC), global theories hypothesize global interaction increases among larger functional brain modules comprising local circuits. We tested the global CER hypothesis using graph-based whole-brain network analysis of functional MRI data during aversive emotional processing with and without CER. During CER, global between-module interaction across stable functional network modules increased. Global interaction increase was particularly driven by subregions of amygdala and cuneus-nodes of highest nodal participation-that overlapped with CER-specific local activations, and by mPFC and posterior cingulate as relevant connector hubs. Results provide evidence for the global nature of human CER, complementing functional specialization of embedded local brain circuits during successful CER. © The Author 2017.

  7. Event-related potentials reveal increased distraction by salient global objects in older adults

    DEFF Research Database (Denmark)

    Wiegand, Iris; Finke, Kathrin; Töllner, Thomas

    Age-related changes in visual functions influence how older individuals perceive and react upon objects in their environment. In particular, older individuals might be more distracted by highly salient, irrelevant information. Kanizsa figures induce a ‘global precedence’ effect, which reflects...... a processing advantage for salient whole-object representations relative to configurations of local elements not inducing a global form. We investigated event-related potential (ERP) correlates of age-related decline in visual abilities, and specifically, distractibility by salient global objects in visual...

  10. Is Global Warming likely to cause an increased incidence of Malaria?

    Science.gov (United States)

    Nabi, SA; Qader, SS

    2009-01-01

    The rise in the average temperature of earth has been described as global warming which is mainly attributed to the increasing phenomenon of the greenhouse effect. It is believed that global warming can have several harmful effects on human health, both directly and indirectly. Since malaria is greatly influenced by climatic conditions because of its direct relationship with the mosquito population, it is widely assumed that its incidence is likely to increase in a future warmer world. This review article discusses the two contradictory views regarding the association of global warming with an increased incidence of malaria. On one hand, there are many who believe that there is a strong association between the recent increase in malaria incidence and global warming. They predict that as global warming continues, malaria is set to spread in locations where previously it was limited, due to cooler climate. On the other hand, several theories have been put forward which are quite contrary to this prediction. There are multiple other factors which are accountable for the recent upsurge of malaria: for example drug resistance, mosquito control programs, public health facilities, and living standards.

  11. CHANGE MANAGEMENT STRATEGIES RELATED TO THE GLOBAL ENVIRONMENT COMPLEXITY

    2016-12-01

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

    2013-01-01

    This paper introduces the Global Resource Balance Table (GRBT), which is an extension of the energy balance tables that expresses the relationships between energy, materials and the environment. The material division of the GRBT includes steel, cement, paper, wood and grain. In contrast, the environmental division of the GRBT includes oxygen, CO 2 and methane. The transaction division rows in the GRBT include production, conversion, end use and stock. Each cell of the GRBT contains the quantities of the respective resources that were generated or consumed. The relationships between the cells were constructed from the laws of conservation of the materials and energy. We constructed a GRBT for 2007 and discussed the increasing air temperature due to waste heat and the CO 2 equivalent from human breathing. The GRBT is a comprehensive integrated table that represents the resources that are consumed by human activities and is useful for energy and environmental studies. - Highlights: • We extended energy balance table and introduced Global Resource Balance Table. • It shows relationships between energy, materials and the environment. • The material division includes steel, cement, paper, wood and grain. • The environmental division includes oxygen, CO 2 and methane. • We discussed on waste heat and CO 2 emission by human breathing

  13. Drivers And Uncertainties Of Increasing Global Water Scarcity

    Science.gov (United States)

    Scherer, L.; Pfister, S.

    2015-12-01

    Water scarcity threatens ecosystems and human health and hampers economic development. It generally depends on the ratio of water consumption to availability. We calculated global, spatially explicit water stress indices (WSIs) which describe the vulnerability to additional water consumption on a scale from 0 (low) to 1 (high) and compare them for the decades 1981-1990 and 2001-2010. Input data are obtained from a multi-model ensemble at a resolution of 0.5 degrees. The variability among the models was used to run 1000 Monte Carlo simulations (latin hypercube sampling) and to subsequently estimate uncertainties of the WSIs. Globally, a trend of increasing water scarcity can be observed, however, uncertainties are large. The probability that this trend is actually occurring is as low as 53%. The increase in WSIs is rather driven by higher water use than lower water availability. Water availability is only 40% likely to decrease whereas water consumption is 67% likely to increase. Independent from the trend, we are already living under water scarce conditions, which is reflected in a consumption-weighted average of monthly WSIs of 0.51 in the recent decade. Its coefficient of variation points with 0.8 to the high uncertainties entailed, which might still hide poor model performance where all models consistently over- or underestimate water availability or use. Especially in arid areas, models generally overestimate availability. Although we do not traverse the planetary boundary of freshwater use as global water availability is sufficient, local water scarcity might be high. Therefore the regionalized assessment of WSIs under uncertainty helps to focus on specific regions to optimise water consumption. These global results can also help to raise awareness of water scarcity, and to suggest relevant measures such as more water efficient technologies to international companies, which have to deal with complex and distributed supply chains (e.g. in food production).

    Two articles of 'Care of coppice in Wood Totoro' and 'Global environment protection from the universe' are included in this report. The former explains the necessity of coppice conservation through an example of Sayama Hill in Tokyo. Until the time 30 years ago, coppices are deeply related to people as the places which supply fuel and fertilizer to villagers, but they have been left or cut down by energy source conversion and development of home lots. Now we must learn the traditional methods of caring coppices again and find a new sense of values regarding the nature. The latter introduces satellite-used remote sensing which allows to continuously scan all the areas of the earth within a short period for global environment protection. This sensor uses a wide range of wavelengths from light to radiowave. In the U.S., it is operated in the name of LANDSAT since 1972, and Japan is also operating various kinds of satellites for environment research concerning, e.g., CO2 concentration and resource exploration. 10 figs.

    Protecting the environment and enhancing food security are among the world's Sustainable Development Goals and greatest challenges. International food trade is an important mechanism to enhance food security worldwide. Nonetheless, it is widely concluded that in international food trade importing countries gain environmental benefits, while exporting countries suffer environmental problems by using land and other resources to produce food for exports. Our study shows that international food trade can also lead to environmental pollution in importing countries. At the global level, our metaanalysis indicates that there was increased nitrogen (N) pollution after much farmland for domestically cultivated N-fixing soybeans in importing countries was converted to grow high N-demanding crops (wheat, corn, rice, and vegetables). The findings were further verified by an intensive study at the regional level in China, the largest soybean-importing country, where the conversion of soybean lands to corn fields and rice paddies has also led to N pollution. Our study provides a sharp contrast to the conventional wisdom that only exports contribute substantially to environmental woes. Our results suggest the need to evaluate environmental consequences of international trade of all other major goods and products in all importing countries, which have significant implications for fundamental rethinking in global policy-making and debates on environmental responsibilities among consumers, producers, and traders across the world.

  16. Increasing global crop harvest frequency: recent trends and future directions

    2013-01-01

    The world’s agricultural systems face the challenge of meeting the rising demands from population growth, changing dietary preferences, and expanding biofuel use. Previous studies have put forward strategies for meeting this growing demand by increasing global crop production, either expanding the area under cultivation or intensifying the crop yields of our existing agricultural lands. However, another possible means for increasing global crop production has received less attention: increasing the frequency of global cropland harvested each year. Historically, many of the world’s croplands were left fallow, or had failed harvests, each year, foregoing opportunities for delivering crop production. Furthermore, many regions, particularly in the tropics, may be capable of multiple harvests per year, often more than are harvested today. Here we analyze a global compilation of agricultural statistics to show how the world’s harvested cropland has changed. Between 2000 and 2011, harvested land area grew roughly 4 times faster than total standing cropland area. Using a metric of cropland harvest frequency (CHF)—the ratio of land harvested each year to the total standing cropland—and its recent trends, we identify countries that harvest their croplands more frequently, and those that have the potential to increase their cropland harvest frequency. We suggest that a possible ‘harvest gap’ may exist in many countries that represents an opportunity to increase crop production on existing agricultural lands. However, increasing the harvest frequency of existing croplands could have significant environmental and social impacts, which need careful evaluation. (letter)

    Intense thunderstorms produce rapid cloud updrafts and may be associated with a range of destructive weather events. An important ingredient in measures of the potential for intense thunderstorms is the convective available potential energy (CAPE). Climate models project increases in summertime mean CAPE in the tropics and subtropics in response to global warming, but the physical mechanisms responsible for such increases and the implications for future thunderstorm activity remain uncertain. Here, we show that high percentiles of the CAPE distribution (CAPE extremes) also increase robustly with warming across the tropics and subtropics in an ensemble of state-of-the-art climate models, implying strong increases in the frequency of occurrence of environments conducive to intense thunderstorms in future climate projections. The increase in CAPE extremes is consistent with a recently proposed theoretical model in which CAPE depends on the influence of convective entrainment on the tropospheric lapse rate, and we demonstrate the importance of this influence for simulated CAPE extremes using a climate model in which the convective entrainment rate is varied. We further show that the theoretical model is able to account for the climatological relationship between CAPE and a measure of lower-tropospheric humidity in simulations and in observations. Our results provide a physical basis on which to understand projected future increases in intense thunderstorm potential, and they suggest that an important mechanism that contributes to such increases may be present in Earth's atmosphere.

  20. Potential Increasing Dominance of Heterotrophy in the Global Ocean

    2016-02-01

    Autotrophs are largely limited by resources in the modern ocean. However, standard metabolic theory suggests continued ocean warming could globally benefit heterotrophs, thereby reducing autotrophic nutrient limitation. The paleo record as well as modern observations offer evidence this has happened in the past and could happen again. Increasing dominance of heterotrophs would result in strong nutrient recycling in the upper ocean and high rates of net primary production (NPP), yet low carbon export to the deep ocean and sediments. We describe the transition towards such a state in the early 22nd century as a response to business-as-usual Representative Concentration Pathway forcing (RCP8.5) in an intermediate complexity Earth system model in three configurations: with and without an explicit calcifier phytoplankton class and calcite ballast model. In all models nutrient regeneration in the near surface becomes an increasingly important driver of primary production. The near-linear relationship between changes in NPP and global sea surface temperature (SST) found over the 21st century becomes exponential above a 2-4 °C global mean SST change. This transition to a more heterotrophic ocean agrees roughly with metabolic theory. Inclusion of small phytoplankton and calcifiers increase the model NPP:SST sensitivity because of their relatively higher nutrient affinity than general phytoplankton. Accounting for organic carbon "protected" from remineralization by carbonate ballast mitigates the exponential increase in NPP and provides an increasingly important pathway for deep carbon export with higher SST changes, despite simultaneous increasing carbonate dissolution rates due to ocean acidification.

    The author has recently been awarded the NSF Career award to develop a radar with cognitive sensing capabilities to study Equatorial plasma instabilities in the Peruvian Andes. Educational research has shown that a rich learning environment contributes tremendously toward improvement in learning achievements and also attitudes toward studies. One of the benefits of this project is that it provides such an environment and a global platform to involve several students at both graduate and undergraduate levels from the US, Puerto Rico, and Peru, and who will benefit from designing, installing, and deploying a radar in multi-instrument science campaigns. In addition to working in the laboratories, students will gain invaluable real world experience building this complex instrument and making it work under challenging conditions at remote sites. The PI will describe how these components are being developed in a Freshman Seminar course and Graduate courses in the Department of Electrical Engineering at Penn State University, and how they are aligned well with the department's and university's strategy for greater global engagement through a network of Global Engagement Nodes in South America (GENSA). The issues of mentoring, recruitment, and retention become particularly important in consideration of the educational objective of this career project to involve underrepresented students with diverse backgrounds and interest them in research projects. The author is working very closely with the Office of Engineering Diversity to leverage existing programs at Penn State designed to increase the participation of women and minority students in science and engineering research: (a) WISER (Women In Science and Engineering Research), and (b) MURE (Minority Undergraduate Research Experience). The Electrical Engineering Department at Penn State is also currently an NSF REU (Research Experience for Undergraduates) site. The PI will also present his efforts in connecting his career

  2. Global risk of big earthquakes has not recently increased.

    2012-01-17

    The recent elevated rate of large earthquakes has fueled concern that the underlying global rate of earthquake activity has increased, which would have important implications for assessments of seismic hazard and our understanding of how faults interact. We examine the timing of large (magnitude M≥7) earthquakes from 1900 to the present, after removing local clustering related to aftershocks. The global rate of M≥8 earthquakes has been at a record high roughly since 2004, but rates have been almost as high before, and the rate of smaller earthquakes is close to its historical average. Some features of the global catalog are improbable in retrospect, but so are some features of most random sequences--if the features are selected after looking at the data. For a variety of magnitude cutoffs and three statistical tests, the global catalog, with local clusters removed, is not distinguishable from a homogeneous Poisson process. Moreover, no plausible physical mechanism predicts real changes in the underlying global rate of large events. Together these facts suggest that the global risk of large earthquakes is no higher today than it has been in the past.

    The current share of sub-Saharan Africa in global carbon dioxide emissions is negligible compared to major contributors like Asia, Americas, and Europe. This trend is, however, likely to change given that both economic growth and rate of urbanization in the region are projected to be robust in the future. The current study contributes to the literature by examining both the direct and the indirect impacts of quality of institution on the environment. Specifically, we investigate whether the institutional setting in the region provides some sort of a complementary role in the environment-FEG relationships. We use the panel two-step system generalized method of moments (GMM) technique to deal with the simultaneity problem. Data consists of 43 sub-Saharan African countries. The result shows that energy inefficiency compromises environmental standards. However, the quality of the institutional setting helps moderate this negative consequences; countries with good institutions show greater prospects than countries with poor institutions. On the other hand, globalization of the region and increased forest size generate positive environmental outcomes in the region. Their impacts are, however, independent of the quality of institution. Afforestation programs, promotion of other clean energy types, and investment in energy efficiency, basic city infrastructure, and regulatory and institutional structures, are desirable policies to pursue to safeguard the environment.

    Full Text Available The main objective of this article is to present the determinants of increase in agricultural commodity prices after 2006. The other specific aim is to show the factors affecting agricultural raw materials and food prices in the global context. This article is a review paper of the determinants of recent commodity and food prices spikes. However, it provides an outlook on these determinants that were the most important for the increases in the last decade. The last part of the article (conclusions to some extent is a synthesis of considerations and includes the authors’ opinions concerning determinants and an attempt to identify which ones were the most important in the growth of agricultural commodity prices. These increases in agricultural commodity prices resulted from many factors and it is very difficult to separate the individual impact of each of them, because they occurred in parallel. However, it is possible to indicate several main reasons for these price increases, which are: adverse changes in supply-demand relations in agricultural markets, increases in oil prices (and increases of the volatility of those prices, development of biofuel production from agricultural commodities (the first generation biofuels, dollar depreciation, an increase in operations of a speculative nature on commodity markets and improper economic policy that created an environment for the growth of prices of agricultural products.

    The response of the terrestrial water cycle to global warming is central to issues including water resources, agriculture and ecosystem health. Recent studies indicate that aridity, defined in terms of atmospheric supply (precipitation, P) and demand (potential evapotranspiration, Ep) of water at the land surface, will increase globally in a warmer world. Recently proposed mechanisms for this response emphasize the driving role of oceanic warming and associated atmospheric processes. Here we show that the aridity response is substantially amplified by land–atmosphere feedbacks associated with the land surface’s response to climate and CO2 change. Using simulations from the Global Land Atmosphere Coupling Experiment (GLACE)-CMIP5 experiment, we show that global aridity is enhanced by the feedbacks of projected soil moisture decrease on land surface temperature, relative humidity and precipitation. The physiological impact of increasing atmospheric CO2 on vegetation exerts a qualitatively similar control on aridity. We reconcile these findings with previously proposed mechanisms by showing that the moist enthalpy change over land is unaffected by the land hydrological response. Thus, although oceanic warming constrains the combined moisture and temperature changes over land, land hydrology modulates the partitioning of this enthalpy increase towards increased aridity.

    2016-12-01

    The abundance of plants with Crassulacean Acid Metabolism (CAM) has increased in many drylands worldwide. This is hypothesized to occur because CAM plants store water, take up CO2 at night, exhibit photosynthetic plasticity, and have high water use efficiency. The increased dominance of CAM plants, however, also depends on their competitive relationship with other functional groups, an aspect of CAM plant sensitivity to global environmental change that has remained largely understudied. Here, we investigated the response of CAM plants and their competitive relationships with C3 and C4 plants under global environmental change. We focused on two pairs of CAM and non-CAM species, namely Cylindropuntia imbricata (a constitutive CAM species) and Bouteloua eriopoda (C4 grass), which co-occur in desert grasslands in northern Mexico, and invasive Mesembryanthemum crystallinum (a facultative CAM species) and Bromus mollis (a C3 invasive grass), which coexist in California's coastal grasslands. A set of growth chamber experiments under altered CO2 and water conditions show that C. imbricata outcompeted B. eriopoda under drought conditions, while in well-watered conditions B. eriopoda was a stronger competitor for soil water than C. imbricata. Under drought conditions a more positive response to CO2 enrichment by C. imbricata indirectly disfavored B. eriopoda, which suggests that interspecific competition can outweigh the favorable direct effect of CO2 enrichment on plant growth. A set of greenhouse experiments under water, N, and soil salinity manipulations showed that drought, N deposition, and/or increased soil salinity served as important drivers for success of M. crystallinum invasion, while B. mollis exerted strong competitive effects on M. crystallinum for light and soil nutrients in well-watered conditions. M. crystallinum switched from C3 photosynthesis to CAM photosynthesis as an adaptive strategy in response to moderate intensity of competition from B. mollis, in

    Precipitation accumulations, integrated over rainfall events, can be affected by both intensity and duration of the storm event. Thus, although precipitation intensity is widely projected to increase under global warming, a clear framework for predicting accumulation changes has been lacking, despite the importance of accumulations for societal impacts. Theory for changes in the probability density function (pdf) of precipitation accumulations is presented with an evaluation of these changes in global climate model simulations. We show that a simple set of conditions implies roughly exponential increases in the frequency of the very largest accumulations above a physical cutoff scale, increasing with event size. The pdf exhibits an approximately power-law range where probability density drops slowly with each order of magnitude size increase, up to a cutoff at large accumulations that limits the largest events experienced in current climate. The theory predicts that the cutoff scale, controlled by the interplay of moisture convergence variance and precipitation loss, tends to increase under global warming. Thus, precisely the large accumulations above the cutoff that are currently rare will exhibit increases in the warmer climate as this cutoff is extended. This indeed occurs in the full climate model, with a 3 °C end-of-century global-average warming yielding regional increases of hundreds of percent to >1,000% in the probability density of the largest accumulations that have historical precedents. The probabilities of unprecedented accumulations are also consistent with the extension of the cutoff.

  12. Capturing value from IP in a global environment

    DEFF Research Database (Denmark)

    Alcacer, Juan; Beukel, Karin; Cassiman, Bruno

    Executive Summary The authors argue that challenges to capturing value from know-how and reputation through the use of different IP tools will be an increasingly important matter of strategy for global enterprises. This has important implications for management practice. Global enterprises...... will need to combine different institutional, market and non-market mechanisms. The precise combination of tools will depend on the local and regional institutional and market conditions. Abstract: This paper documents the strong growth in tools used by firms to protect their intellectual property (IP......), develop their know-how, and build and maintain their reputation globally during the last decades. We focus on three tools: patents, trademarks, and industrial designs. We find that, although most IP applications come from a few countries (the United States, European Union, Japan, China, and South Korea...

  15. Changes in the Global Energy System: Implications for China's International Strategic Environment

    Directory of Open Access Journals (Sweden)

    Zhang Chi

    2015-12-01

    Full Text Available This article briefly discusses major reasons for the slump of international oil prices and provides a prediction for the future development of international oil prices, before analyzing the three factors leading to significant changes of the global energy system, namely the eastward shift of the world energy consumption centre, the emergence of the United States as a major oil producer and the dramatic waning of the Organization of Petroleum Exporting Countries’ (OPEC influence. These factors and developments are shaping a new order of the global energy strategic landscape and exerting profound influence on China’s international strategic environment. In the foreseeable future, these changes of the global energy system would bring China more uncertainties regarding the country’s oil imports from the Middle East, more strategic pressure from the United States, while promoting China’s leverage on the global energy system and international relations.

  16. How warm days increase belief in global warming

    2014-02-01

    Climate change judgements can depend on whether today seems warmer or colder than usual, termed the local warming effect. Although previous research has demonstrated that this effect occurs, studies have yet to explain why or how temperature abnormalities influence global warming attitudes. A better understanding of the underlying psychology of this effect can help explain the public's reaction to climate change and inform approaches used to communicate the phenomenon. Across five studies, we find evidence of attribute substitution, whereby individuals use less relevant but available information (for example, today's temperature) in place of more diagnostic but less accessible information (for example, global climate change patterns) when making judgements. Moreover, we rule out alternative hypotheses involving climate change labelling and lay mental models. Ultimately, we show that present temperature abnormalities are given undue weight and lead to an overestimation of the frequency of similar past events, thereby increasing belief in and concern for global warming.

    Cloud computing system is a huge cluster of interconnected servers residing in a datacenter and dynamically provisioned to clients on-demand via a front-end interface. Scientific applications scheduling in the cloud computing environment is identified as NP-hard problem due to the dynamic nature of heterogeneous resources. Recently, a number of metaheuristics optimization schemes have been applied to address the challenges of applications scheduling in the cloud system, without much emphasis on the issue of secure global scheduling. In this paper, scientific applications scheduling techniques using the Global League Championship Algorithm (GBLCA) optimization technique is first presented for global task scheduling in the cloud environment. The experiment is carried out using CloudSim simulator. The experimental results show that, the proposed GBLCA technique produced remarkable performance improvement rate on the makespan that ranges between 14.44% to 46.41%. It also shows significant reduction in the time taken to securely schedule applications as parametrically measured in terms of the response time. In view of the experimental results, the proposed technique provides better-quality scheduling solution that is suitable for scientific applications task execution in the Cloud Computing environment than the MinMin, MaxMin, Genetic Algorithm (GA) and Ant Colony Optimization (ACO) scheduling techniques.

  4. Knowledge-inducing Global Path Planning for Robots in Environment with Hybrid Terrain

    Directory of Open Access Journals (Sweden)

    Yi-nan Guo

    2010-09-01

    Full Text Available In complex environment with hybrid terrain, different regions may have different terrain. Path planning for robots in such environment is an open NP-complete problem, which lacks effective methods. The paper develops a novel global path planning method based on common sense and evolution knowledge by adopting dual evolution structure in culture algorithms. Common sense describes terrain information and feasibility of environment, which is used to evaluate and select the paths. Evolution knowledge describes the angle relationship between the path and the obstacles, or the common segments of paths, which is used to judge and repair infeasible individuals. Taken two types of environments with different obstacles and terrain as examples, simulation results indicate that the algorithm can effectively solve path planning problem in complex environment and decrease the computation complexity for judgment and repair of infeasible individuals. It also can improve the convergence speed and have better computation stability.

  5. Childhood socioeconomic status and risk in early family environments: predictors of global sleep quality in college students.

    2018-06-01

    Low socioeconomic status (SES) in childhood associates with poor sleep quality in adulthood. Separately, childhood family environments shape health into adulthood. Here, we investigated whether these early life factors independently or interactively inform global sleep quality in college students. Cross-sectional. College students at a state university (N = 391). As a measure of childhood SES, we asked participants to consider their families' socioeconomic standing relative to the rest of the society during their childhood. We used the Risky Family questionnaire to measure adversity and the presence of warmth and affection in the family environment during childhood, and the Pittsburgh Sleep Quality Index as a measure of current global sleep quality. We used linear regressions adjusting for age and sex to examine relationships between childhood SES, risk in childhood family environments, and global sleep quality. Lower childhood SES and greater risk in childhood family environments independently predicted poor sleep quality. Importantly, in low-risk family environments, there was no significant difference in sleep quality as a function of childhood SES. However, students who were from low childhood SES backgrounds who also reported high levels of risk in their early family environments had the worst sleep quality. Findings highlight the importance of considering socioeconomic and family environments in childhood as informants of sleep quality across the lifespan. Compromised sleep quality in college students could affect academic performance and health over time. Copyright © 2018 National Sleep Foundation. Published by Elsevier Inc. All rights reserved.

    The close relationship between human health, performance, well-being and the thermal environment is obvious. Nevertheless, most studies of climate and climate change impacts show amazing shortcomings in the assessment of the environment. Populations living in different climates have different susceptibilities, due to socio-economic reasons, and different customary behavioural adaptations. The global distribution of risks of hazardous thermal exposure has not been analysed before. To produce maps of the baseline and future bioclimate that allows a direct comparison of the differences in the vulnerability of populations to thermal stress across the world. The required climatological data fields are obtained from climate simulations with the global General Circulation Model ECHAM4 in T106-resolution. For the thermo-physiologically relevant assessment of these climate data a complete heat budget model of the human being, the 'Perceived Temperature' procedure has been applied which already comprises adaptation by clothing to a certain degree. Short-term physiological acclimatisation is considered via Health Related Assessment of the Thermal Environment. The global maps 1971-1980 (control run, assumed as baseline climate) show a pattern of thermal stress intensities as frequencies of heat. The heat load for people living in warm-humid climates is the highest. Climate change will lead to clear differences in health-related thermal stress between baseline climate and the future bioclimate 2041-2050 based on the 'business-as-usual' greenhouse gas scenario IS92a. The majority of the world's population will be faced with more frequent and more intense heat strain in spite of an assumed level of acclimatisation. Further adaptation measures are crucial in order to reduce the vulnerability of the populations. This bioclimatology analysis provides a tool for various questions in climate and climate change impact research. Considerations of regional or local scale require climate

  7. Observations of urban and suburban environments with global satellite scatterometer data

    A global and consistent characterization of land use and land change in urban and suburban environments is crucial for many fundamental social and natural science studies and applications. Presented here is a dense sampling method (DSM) that uses satellite scatterometer data to delineate urban and intraurban areas at a posting scale of about 1 km. DSM results are analyzed together with information on population and housing censuses, with Landsat Enhanced Thematic Mapper Plus (ETM+) imagery, and with Defense Meteorological Satellite Program (DMSP) night-light data. The analyses include Dallas-Fort Worth and Phoenix in the United States, Bogotá in Colombia, Dhaka in Bangladesh, Guangzhou in China, and Quito in Ecuador. Results show that scatterometer signatures correspond to buildings and infrastructures in urban and suburban environments. City extents detected by scatterometer data are significantly smaller than city light extents, but not all urban areas are detectable by the current SeaWinds scatterometer on the QuikSCAT satellite. Core commercial and industrial areas with high buildings and large factories are identified as high-backscatter centers. Data from DSM backscatter and DMSP nighttime lights have a good correlation with population density. However, the correlation relations from the two satellite datasets are different for different cities indicating that they contain complementary information. Together with night-light and census data, DSM and satellite scatterometer data provide new observations to study global urban and suburban environments and their changes. Furthermore, the capability of DSM to identify hydrological channels on the Greenland ice sheet and ecological biomes in central Africa demonstrates that DSM can be used to observe persistent structures in natural environments at a km scale, providing contemporaneous data to study human impacts beyond urban and suburban areas.

    2018-04-30

    The recent levelling of global mean temperatures after the late 1990s, the so-called global warming hiatus or slowdown, ignited a surge of scientific interest into natural global mean surface temperature variability, observed temperature biases, and climate communication, but many questions remain about how these findings relate to variations in more societally relevant temperature extremes. Here we show that both summertime warm and wintertime cold extreme occurrences increased over land during the so-called hiatus period, and that these increases occurred for distinct reasons. The increase in cold extremes is associated with an atmospheric circulation pattern resembling the warm Arctic-cold continents pattern, whereas the increase in warm extremes is tied to a pattern of sea surface temperatures resembling the Atlantic Multidecadal Oscillation. These findings indicate that large-scale factors responsible for the most societally relevant temperature variations over continents are distinct from those of global mean surface temperature.

  12. Modeling and Monitoring Terrestrial Primary Production in a Changing Global Environment: Toward a Multiscale Synthesis of Observation and Simulation

    Directory of Open Access Journals (Sweden)

    Shufen Pan

    2014-01-01

    Full Text Available There is a critical need to monitor and predict terrestrial primary production, the key indicator of ecosystem functioning, in a changing global environment. Here we provide a brief review of three major approaches to monitoring and predicting terrestrial primary production: (1 ground-based field measurements, (2 satellite-based observations, and (3 process-based ecosystem modelling. Much uncertainty exists in the multi-approach estimations of terrestrial gross primary production (GPP and net primary production (NPP. To improve the capacity of model simulation and prediction, it is essential to evaluate ecosystem models against ground and satellite-based measurements and observations. As a case, we have shown the performance of the dynamic land ecosystem model (DLEM at various scales from site to region to global. We also discuss how terrestrial primary production might respond to climate change and increasing atmospheric CO2 and uncertainties associated with model and data. Further progress in monitoring and predicting terrestrial primary production requires a multiscale synthesis of observations and model simulations. In the Anthropocene era in which human activity has indeed changed the Earth’s biosphere, therefore, it is essential to incorporate the socioeconomic component into terrestrial ecosystem models for accurately estimating and predicting terrestrial primary production in a changing global environment.

  13. Subterranean karst environments as a global sink for atmospheric methane

    Webster, Kevin D.; Drobniak, Agnieszka; Etiope, Giuseppe; Mastalerz, Maria; Sauer, Peter E.; Schimmelmann, Arndt

    2018-03-01

    The air in subterranean karst cavities is often depleted in methane (CH4) relative to the atmosphere. Karst is considered a potential sink for the atmospheric greenhouse gas CH4 because its subsurface drainage networks and solution-enlarged fractures facilitate atmospheric exchange. Karst landscapes cover about 14% of earth's continental surface, but observations of CH4 concentrations in cave air are limited to localized studies in Gibraltar, Spain, Indiana (USA), Vietnam, Australia, and by incomplete isotopic data. To test if karst is acting as a global CH4 sink, we measured the CH4 concentrations, δ13CCH4, and δ2HCH4 values of cave air from 33 caves in the USA and three caves in New Zealand. We also measured CO2 concentrations, δ13CCO2, and radon (Rn) concentrations to support CH4 data interpretation by assessing cave air residence times and mixing processes. Among these caves, 35 exhibited subatmospheric CH4 concentrations in at least one location compared to their local atmospheric backgrounds. CH4 concentrations, δ13CCH4, and δ2HCH4 values suggest that microbial methanotrophy within caves is the primary CH4 consumption mechanism. Only 5 locations from 3 caves showed elevated CH4 concentrations compared to the atmospheric background and could be ascribed to local CH4 sources from sewage and outgassing swamp water. Several associated δ13CCH4 and δ2HCH4 values point to carbonate reduction and acetate fermentation as biochemical pathways of limited methanogenesis in karst environments and suggest that these pathways occur in the environment over large spatial scales. Our data show that karst environments function as a global CH4 sink.

  14. Toward an Assessment of the Global Inventory of Present-Day Mercury Releases to Freshwater Environments

    Directory of Open Access Journals (Sweden)

    2017-02-01

    Full Text Available Aquatic ecosystems are an essential component of the biogeochemical cycle of mercury (Hg, as inorganic Hg can be converted to toxic methylmercury (MeHg in these environments and reemissions of elemental Hg rival anthropogenic Hg releases on a global scale. Quantification of effluent Hg releases to aquatic systems globally has focused on discharges to the global oceans, rather than contributions to freshwater systems that affect local exposures and risks associated with MeHg. Here we produce a first-estimate of sector-specific, spatially resolved global aquatic Hg discharges to freshwater systems. We compare our release estimates to atmospheric sources that have been quantified elsewhere. By analyzing available quantitative and qualitative information, we estimate that present-day global Hg releases to freshwater environments (rivers and lakes associated with anthropogenic activities have a lower bound of ~1000 Mg· a−1. Artisanal and small-scale gold mining (ASGM represents the single largest source, followed by disposal of mercury-containing products and domestic waste water, metal production, and releases from industrial installations such as chlor-alkali plants and oil refineries. In addition to these direct anthropogenic inputs, diffuse inputs from land management activities and remobilization of Hg previously accumulated in terrestrial ecosystems are likely comparable in magnitude. Aquatic discharges of Hg are greatly understudied and further constraining associated data gaps is crucial for reducing the uncertainties in the global biogeochemical Hg budget.

  15. ABB and the global market

    1994-01-01

    Competing in a global environment implies that the authors previous business environment has been less than global, and there are indeed changes underway that lead to a more universal environment. But, there are still differences between regions and especially between the mature economies in the OECD countries and the rapidly developing countries, of which a majority are in Asia. For the OECD countries, the time after World War 2 and up to about 1970 was a period of unprecedented growth. Rebuilding after the war and a general growth of the use of electric power required high investments in power systems and caused a booming market for equipment suppliers. After a trend break in the beginning of the 1970s to less than 40 GW 10 years later, then slowly increased to about 50 GW today. At the same time, annual capacity growth in developing countries increased from less than 20 GW to about 50 GW, i.e. the same level as in OECD. This means that ABB is now passing a cross-over point: from now on less than half of their global market is in their well-known OECD world. And this share will continue to shrink. ABB is now restructuring to fulfill market needs in less developed, developing, and newly industrialized countries. This is the most important change in their global environment is addressed in this article

  16. The impact of German biogas production on European and global agricultural markets, land use and the environment

    Britz, Wolfgang; Delzeit, Ruth

    2013-01-01

    As part of its climate policy, Germany promotes the production of biogas via its so-called Renewable-Energy-Act (EEG). The resulting boost in biogas output went along with a significant increase in production of green maize, the dominant feedstock. Existing studies of the EEG have analysed its impacts on German agriculture without considering market feedback. We thus expand existing quantitative analysis by also considering impacts on European and global agricultural markets, land use and the environment by combining a detailed location model for biogas plants, the Regionalised Location Information System-Maize (ReSi-M2012), with a global Partial Equilibrium model for agriculture, the Common Agricultural Policy Regional Impact (CAPRI) model. Our results indicate that the German biogas production is large enough to have sizeable impacts on global agricultural markets in prices and quantities, causing significant land use change outside of Germany. While profits in the agricultural sector increase, food consumer face higher prices, and subsidies for biogas production are passed on to electricity consumers. The German biogas program, as long as it is almost entirely based on non-waste feedstocks, is probably not a promising avenue towards a GHG-saving renewable energy production, but a rather expensive one. - Highlights: • Recent changes to that program decrease green maize use but increase land demands. • The program could raise EU prices for cereals by 3%. • Agricultural land use expansion outside of the EU estimated at 1 Mio ha

    Pastures and rangelands underpin global meat and milk production and are a critical resource for millions of people dependent on livestock for food security1,2. Forage growth, which is highly climate dependent3,4, is potentially vulnerable to climate change, although precisely where and to what extent remains relatively unexplored. In this study, we assess climate-based threats to global pastures, with a specific focus on changes in within- and between-year precipitation variability (precipitation concentration index (PCI) and coefficient of variation of precipitation (CVP), respectively). Relating global satellite measures of vegetation greenness (such as the Normalized Difference Vegetation Index; NDVI) to key climatic factors reveals that CVP is a significant, yet often overlooked, constraint on vegetation productivity across global pastures. Using independent stocking data, we found that areas with high CVP support lower livestock densities than less-variable regions. Globally, pastures experience about a 25% greater year-to-year precipitation variation (CVP = 0.27) than the average global land surface area (0.21). Over the past century, CVP has generally increased across pasture areas, although both positive (49% of pasture area) and negative (31% of pasture area) trends exist. We identify regions in which livestock grazing is important for local food access and economies, and discuss the potential for pasture intensification in the context of long-term regional trends in precipitation variability.

  3. European strategy/global strategy

    1998-08-01

    In order to be `global`, a carmaker has to satisfy three main criteria: a global customer service, a global market presence, a global respect for the environment. Just in a word, the automotive industry needs to develop - and has indeed already launched - a process of global re-engineering of its: product, processes, and market. The product is not simply a `car`, but a global mobility service. This is what an increasingly diversified clientele is demanding in order to meet its particular mobility needs in terms of comfort and safety, in a way that does not damage the environment and at welldefined, competitive costs. The process is not just a matter of the way we design, manufacture and distribute our product. We have to re-design our entire corporate profile, redefine the parameters of our specific strategic mission, identifying the levels of control and our core business in a way that is consistent with our particular history, market positioning and growth targets. The market is no longer hard set, but is globally diversified, ready to expand into important niches and to meet the personalized needs of specific users: from VIPs to the elderly or the disables, and so on.

    Full Text Available Distance education system in India has undergone many stages and phases of evolution before it really reached the stage of what is called open education, ICT-enabled education and global education. During these phases, it has assimilated different aspects of ICT with all applauds and has been able to go hand-in-hand with it transcending the national and regional boundaries. The distance education institutions have now started giving a serious thought to explore the possibility of cross-boarder expansion. The educational needs of the present society are changing very fast. The education is now being seen as an enabling tool for empowerment and all-round development of individuals. It is difficult for an institution to come up to all the educational requirements of the society. It is, therefore, time to collaborate rather than compete. Quality concern becomes a serious issue in such a situation. Consequently, globalization, internationalization, collaboration, networking have become the buzzwords of the day in distance education. In furtherance of this journey, Indira National Open University, INDIA organized an international conference on the theme “Open and Distance Education in Global Environment: Opportunities for Collaboration” under the aegis of International Council for Distance Education. The articles of the renowned educationists presented in the Conference have reserved their place in the volume under review. The volume is a repository of their experiences in the becoming of distance education all these years. The volume is spread over 32 chapters summed up into four major streams– internationalization are: collaboration and networking; ICT-enabled education; quality assurance; and distance education for development. The canvas of the volume covers the present scenario of open and distance education from the global perspective.The first part discusses as to how collaboration can be tamed to develop joint curriculum and deliver

    As the world becomes increasingly interconnected, exposure to global cultures affords individuals opportunities to develop global identities. In two studies, we examine the antecedents and outcomes of identifying with a superordinate identity--global citizen. Global citizenship is defined as awareness, caring, and embracing cultural diversity while promoting social justice and sustainability, coupled with a sense of responsibility to act. Prior theory and research suggest that being aware of one's connection with others in the world (global awareness) and embedded in settings that value global citizenship (normative environment) lead to greater identification with global citizens. Furthermore, theory and research suggest that when global citizen identity is salient, greater identification is related to adherence to the group's content (i.e., prosocial values and behaviors). Results of the present set of studies showed that global awareness (knowledge and interconnectedness with others) and one's normative environment (friends and family support global citizenship) predicted identification with global citizens, and global citizenship predicted prosocial values of intergroup empathy, valuing diversity, social justice, environmental sustainability, intergroup helping, and a felt responsibility to act for the betterment of the world. The relationship between antecedents (normative environment and global awareness) and outcomes (prosocial values) was mediated by identification with global citizens. We discuss the relationship between the present results and other research findings in psychology, the implications of global citizenship for other academic domains, and future avenues of research. Global citizenship highlights the unique effect of taking a global perspective on a multitude of topics relevant to the psychology of everyday actions, environments, and identity.

    Full Text Available Indoor thermal environment is one of the criteria in sustainable building. This criterion is important in ensuring a healthy indoor environment for the occupants. The consideration of environmental concerns at the early design stage would effectively integrate the sustainability of the building environment. Global climate changes such as global warming do affect human comfort since people spend most of their time and activities in the building. The increasing of urban population required additional housing for households, as well as places to shop, office and other facilities. Occupants are now more conscious the importance of sustainability for a better quality of life. Good thermal environment is essential for human wellness and comfort. A residential environment will influence residents’ health and safety. The global warming increase the earth’s temperature and greenhouse emission to the atmosphere cause adverse effects to the outdoor environment. Residential developments modify the materials, structure and energy balance in urban climate effects of human economic activities. As an indoor environment is influenced by the outdoor condition, the factors affecting indoor thermal environment are crucial in improving a comfortable and healthy environment in residential building. The microclimatic of a site such as temperature and relative humidity, and wind movement led to the variation of indoor thermal environment in the building.

    The Scientific Committee on Problems of the Environment (SCOPE) has organized an international project to synthesize and advance current theory on the influence of ecotones, or transition zones between ecosystems, on biodiversity and flows of energy, nutrients, water, and project is other materials between ecosystems. In particular, the entire project is designed to evaluate the influence of global climate change and land-use practices on biodiversity and ecological flows associated with ecotones, and will assess the feasibility of monitoring ecotones as early indicators of global change. The later stages of the project will recommend landscape management strategies for ecotones that produce desirable patterns of biodiversity and ecological flows. The result of the project--a comprehensive body of information on the theory and management of biodiversity and ecological flows associated with ecotones--will be part of the planning for research to be carried out under the International Geosphere-Biosphere Program.

    2013-12-01

    Physical inactivity has been recognised by the World Health Organization as one of the leading causes of death due to non-communicable disease (NCD), worldwide. The benefits of action over inactivity can cut across health, environment, transportation, sport, culture and the economy. Despite the evidence, the policies and strategies to increase population-wide participation in physical activity receive insufficient priority from across high, middle and low-income countries; where physical inactivity is a rapidly-emerging issue. There is an increased need for all countries to invest in policies, strategies and supportive environments that inform, motivate and support individuals and communities to be active in ways that are safe, accessible and enjoyable. This commentary presents some recent efforts towards physical activity promotion globally, led by the Global Advocacy for Physical Activity (GAPA). It provides an overview of the background and history of GAPA; describes GAPA and the council's key achievements and milestones; places physical activity promotion within the global NCD agenda; presents GAPA flagships; and reflects on the lessons learned, ingredients for success and the major challenges that remain. The commentary documents insights into the effectiveness and challenges faced by a small non-governmental organisation (NGO) in mounting global advocacy. These lessons may be transferrable to other areas of health promotion advocacy.

    The global energy situation is rapidly changing. Global oil and gas trade is increasing, in an environment of rising prices, higher costs, greater environmental concerns, and growing security uncertainties. While predictions of shortages through depletion of oil and gas reserves are unfounded, the world must adapt to higher prices and changing trade patterns, as conventional reserves are increasingly being replaced un-conventional resources. Canada, drawing upon its vast natural resources and technological innovation, is positioned to be an even more important global energy leader in the 21st century. (author)

    2009-06-01

    Full Text Available Current global warming affects the composition and dynamics of mammalian communities and can increase extinction risk; however, long-term effects of warming on mammals are less understood. Dietary reconstructions inferred from stable isotopes of fossil herbivorous mammalian tooth enamel document environmental and climatic changes in ancient ecosystems, including C(3/C(4 transitions and relative seasonality.Here, we use stable carbon and oxygen isotopes preserved in fossil teeth to document the magnitude of mammalian dietary shifts and ancient floral change during geologically documented glacial and interglacial periods during the Pliocene (approximately 1.9 million years ago and Pleistocene (approximately 1.3 million years ago in Florida. Stable isotope data demonstrate increased aridity, increased C(4 grass consumption, inter-faunal dietary partitioning, increased isotopic niche breadth of mixed feeders, niche partitioning of phylogenetically similar taxa, and differences in relative seasonality with warming.Our data show that global warming resulted in dramatic vegetation and dietary changes even at lower latitudes (approximately 28 degrees N. Our results also question the use of models that predict the long term decline and extinction of species based on the assumption that niches are conserved over time. These findings have immediate relevance to clarifying possible biotic responses to current global warming in modern ecosystems.

    There is an urgent need to ensure food supply for a growing global population. To enable a sustainable growth of agricultural production, effective and timely information is required to support decision making and to improve management of agricultural resources. This requires innovative ways and monitoring methods that will not only improve short-term crop production forecasts, but also allow to assess changes in cultivation practices, agricultural areas, agriculture in general and, its impact on the environment. The G20 launched in June 2011 the "GEO Global Agricultural Monitoring initiative (GEOGLAM), requesting the GEO (Group on Earth Observations) Agricultural Community of Practice to implement GEOGLAM with the main objective to improve crop yield forecasts as an input to the Agricultural Market Information System (AMIS), in order to foster stabilisation of markets and increase transparency on agricultural production. In response to this need, the European Commission decided in 2013 to fund an international partnership to contribute to GEOGLAM and its research agenda. The resulting SIGMA project (Stimulating Innovation for Global Monitoring of Agriculture), a partnership of 23 globally distributed expert organisations, focusses on developing datasets and innovative techniques in support of agricultural monitoring and its impact on the environment in support of GEOGLAM. SIGMA has 3 generic objectives which are: (i) develop and test methods to characterise cropland and assess its changes at various scales; (ii) develop and test methods to assess changes in agricultural production levels; and; (iii) study environmental impacts of agriculture. Firstly, multi-scale remote sensing data sets, in combination with field and other ancillary data, will be used to generate an improved (global) agro-ecological zoning map and crop mask. Secondly, a combination of agro-meteorological models, satellite-based information and long-term time series will be explored to assess crop

    Tracking antibiotic consumption patterns over time and across countries could inform policies to optimize antibiotic prescribing and minimize antibiotic resistance, such as setting and enforcing per capita consumption targets or aiding investments in alternatives to antibiotics. In this study, we analyzed the trends and drivers of antibiotic consumption from 2000 to 2015 in 76 countries and projected total global antibiotic consumption through 2030. Between 2000 and 2015, antibiotic consumption, expressed in defined daily doses (DDD), increased 65% (21.1–34.8 billion DDDs), and the antibiotic consumption rate increased 39% (11.3–15.7 DDDs per 1,000 inhabitants per day). The increase was driven by low- and middle-income countries (LMICs), where rising consumption was correlated with gross domestic product per capita (GDPPC) growth (P = 0.004). In high-income countries (HICs), although overall consumption increased modestly, DDDs per 1,000 inhabitants per day fell 4%, and there was no correlation with GDPPC. Of particular concern was the rapid increase in the use of last-resort compounds, both in HICs and LMICs, such as glycylcyclines, oxazolidinones, carbapenems, and polymyxins. Projections of global antibiotic consumption in 2030, assuming no policy changes, were up to 200% higher than the 42 billion DDDs estimated in 2015. Although antibiotic consumption rates in most LMICs remain lower than in HICs despite higher bacterial disease burden, consumption in LMICs is rapidly converging to rates similar to HICs. Reducing global consumption is critical for reducing the threat of antibiotic resistance, but reduction efforts must balance access limitations in LMICs and take account of local and global resistance patterns.

  18. Sustainable development goals for global health: facilitating good governance in a complex environment.

    Haffeld, Just

    2013-11-01

    Increasing complexity is following in the wake of rampant globalization. Thus, the discussion about Sustainable Development Goals (SDGs) requires new thinking that departs from a critique of current policy tools in exploration of a complexity-friendly approach. This article argues that potential SDGs should: treat stakeholders, like states, business and civil society actors, as agents on different aggregate levels of networks; incorporate good governance processes that facilitate early involvement of relevant resources, as well as equitable participation, consultative processes, and regular policy and programme implementation reviews; anchor adoption and enforcement of such rules to democratic processes in accountable organizations; and include comprehensive systems evaluations, including procedural indicators. A global framework convention for health could be a suitable instrument for handling some of the challenges related to the governance of a complex environment. It could structure and legitimize government involvement, engage stakeholders, arrange deliberation and decision-making processes with due participation and regular policy review, and define minimum standards for health services. A monitoring scheme could ensure that agents in networks comply according to whole-systems targets, locally defined outcome indicators, and process indicators, thus resolving the paradox of government control vs. local policy space. A convention could thus exploit the energy created in the encounter between civil society, international organizations and national authorities. Copyright © 2013 Reproductive Health Matters.

    2014-09-23

    There has been a resurgence of interest in the impacts of agricultural productivity on land use and the environment. At the center of this debate is the assertion that agricultural innovation is land sparing. However, numerous case studies and global empirical studies have found little evidence of higher yields being accompanied by reduced area. We find that these studies overlook two crucial factors: estimation of a true counterfactual scenario and a tendency to adopt a regional, rather than a global, perspective. This paper introduces a general framework for analyzing the impacts of regional and global innovation on long run crop output, prices, land rents, land use, and associated CO2 emissions. In so doing, it facilitates a reconciliation of the apparently conflicting views of the impacts of agricultural productivity growth on global land use and environmental quality. Our historical analysis demonstrates that the Green Revolution in Asia, Latin America, and the Middle East was unambiguously land and emissions sparing, compared with a counterfactual world without these innovations. In contrast, we find that the environmental impacts of a prospective African Green Revolution are potentially ambiguous. We trace these divergent outcomes to relative differences between the innovating region and the rest of the world in yields, emissions efficiencies, cropland supply response, and intensification potential. Globalization of agriculture raises the potential for adverse environmental consequences. However, if sustained for several decades, an African Green Revolution will eventually become land sparing.

    International Nuclear Information System (INIS)

    2012-01-01

    According to the Millennium Development Goals, managing the environment is considered an integral part of the global development process. The main purpose of the IAEA's environment laboratories is to provide Member States with reliable information on environmental issues and facilitate decision making on protection of the environment. An increasingly important feature of this work is to assess the impact of climate change on environmental sustainability and natural resources. The IAEA's environment laboratories use nuclear techniques, radionuclides, isotopic tracers and stable isotopes to gain a better understanding of the various marine processes, including locating the sources of pollutants and their fate, their transport pathways and their ultimate accumulation in sediments. Radioisotopes are also used to study bioaccumulation in organisms and the food chain, as well as to track signals of climate change throughout history. Natural and artificial radionuclides are used to track ocean currents in key regions. They are also used to validate models designed to predict the future impact of climate change and ocean acidification. The laboratories study the fate and impact of contamination on a variety of ecosystems in order to provide effective preventative diagnostic and remediation strategies. They enhance the capability of Member States to use nuclear techniques to understand and assess changes in their own terrestrial and atmospheric environments, and adopt suitable and sustainable remediation measures when needed. Since 1995, the IAEA environment laboratories have coordinated the international network of Analytical Laboratories for the Measurement of Environmental Radioactivity, providing accurate analysis in the event of an accident or an intentional release of radioactivity. In addition, the laboratories work alongside other organizations, such as UNESCO, the IOC, UNEP and the EC. The laboratories collaborate with Member States through direct involvement with

  4. How can increased use of biological N2 fixation in agriculture benefit the environment?

    International Nuclear Information System (INIS)

    Jensen, Erik Steen; Hauggaard-Nielsen, Henrik

    2001-01-01

    Asymbiotic, associative or symbiotic biological N 2 fixation (BNF), is a free and renewable resource, which should constitute an integral part of sustainable agro-ecosystems. Yet there has been a rapid increase in use of fertiliser N and a parallel decline in the cultivation of leguminous plants and BNF, especially in the developed world. Fertilisers have boosted crop yields, but intensive agricultural systems have increasingly negative effects on the atmospheric and aquatic environments. BNF, either alone or in combination with fertilisers and animal manures, may prove to be a better solution to supply nitrogen to the cropping systems of the future. This review focuses on the potential benefit of BNF on the environment especially on soil acidification, rhizosphere processes and plant CO 2 fixation. As fertiliser N has supplanted BNF in agriculture the re-substitution of BNF is considered. What is the consequence of fertiliser N production on energy use? The effect of fertiliser use on the release of the greenhouse gas CO 2 is estimated at approximately 1 % of the global anthropogenic emission of CO 2 . The role of BNF on nitrogen cycling, ammonia volatilisation, N 2 O emission and NO 3 leaching suggests that BNF is less likely than fertilisers to cause losses during pre-cropping and cropping. Sometimes however the post-harvest losses may be greater, due to the special qualities of legume residues. Nevertheless, legumes provide other 'ecological services' including improved soil structure, erosion protection and greater biological diversity. (author)

  5. Leveraging non-binding instruments for global health governance: reflections from the Global AIDS Reporting Mechanism for WHO reform.

    2014-02-01

    As countries contend with an increasingly complex global environment with direct implications for population health, the international community is seeking novel mechanisms to incentivize coordinated national and international action towards shared health goals. Binding legal instruments have garnered increasing attention since the World Health Organization adopted its first convention in 2003. This paper seeks to expand the discourse on future global health lawmaking by exploring the potential value of non-binding instruments in global health governance, drawing on the case of the 2001 United Nations General Assembly Special Session Declaration of Commitment on HIV/AIDS. In other realms of international concern ranging from the environment to human rights to arms control, non-binding instruments are increasingly used as effective instruments of international cooperation. The experience of the Global AIDS Reporting Mechanism, established pursuant to the Declaration, evidences that, at times, non-binding legal instruments can offer benefits over slower, more rigid binding legal approaches to governance. The global AIDS response has demonstrated that the use of a non-binding instrument can be remarkably effective in galvanizing increasingly deep commitments, action, reporting compliance and ultimately accountability for results. Based on this case, the authors argued that non-binding instruments deserve serious consideration by the international community for the future of global health governance, including in the context of WHO reform.

    The food production system is increasingly global and seafood is among the most highly traded commodities. Global trade can improve food security by providing access to a greater variety of foods, increasing wealth, buffering against local supply shocks, and benefit the environment by increasing overall use efficiency for some resources. However, global trade can also expose countries to external supply shocks and degrade the environment by increasing resource demand and loosening feedbacks between consumers and the impacts of food production. As a result, changes in global food trade can have important implications for both food security and the environmental impacts of production. Measurements of globalization and the environmental impacts of food production require data on both total trade and the origin and destination of traded goods (the network structure). While the global trade network of agricultural and livestock products has previously been studied, seafood products have been excluded. This study describes the structure and evolution of the global seafood trade network, including metrics quantifying the globalization of seafood, shifts in bilateral trade flows, changes in centrality and comparisons of seafood to agricultural and industrial trade networks. From 1994 to 2012 the number of countries trading in the network remained relatively constant, while the number of trade partnerships increased by over 65%. Over this same period, the total quantity of seafood traded increased by 58% and the value increased 85% in real terms. These changes signify the increasing globalization of seafood products. Additionally, the trade patterns in the network indicate: increased influence of Thailand and China, strengthened intraregional trade, and increased exports from South America and Asia. In addition to characterizing these network changes, this study identifies data needs in order to connect seafood trade with environmental impacts and food security outcomes.

    Recent advancement of land-based mobile mapping enables rapid and cost-effective collection of highquality road related spatial information. Mobile Mapping Systems (MMS) can provide spatial information with subdecimeter accuracy in nominal operation environments. However, performance in challenging environments such as tunnels is not well characterized. The Norwegian Public Roads Administration (NPRA) manages the country's public road network and its infrastructure, a large segment of which is represented by road tunnels (there are about 1 000 road tunnels in Norway with a combined length of 800 km). In order to adopt mobile mapping technology for streamlining road network and infrastructure management and maintenance tasks, it is important to ensure that the technology is mature enough to meet existing requirements for object positioning accuracy in all types of environments, and provide homogeneous accuracy over the mapping perimeter. This paper presents results of a testing campaign performed within a project funded by the NPRA as a part of SMarter road traffic with Intelligent Transport Systems (ITS) (SMITS) program. The testing campaign objective was performance evaluation of high end commercial MMSs for inventory of public areas, focusing on Global Navigation Satellite System (GNSS) signal degraded environments.

    Full Text Available Ever more extensive use of marine space by human activities and greater demands for marine natural resources has led to increases in both duration and spatial extent of pressures on the marine environment. In parallel, the global crisis of decreasing biodiversity and loss of habitats has revitalized scientific research on human impacts and lead to methodological development of cumulative pressure and impact assessments (CPIA. In Europe alone, almost twenty CPIAs have been published in the past 10 years and some more in other sea regions of the world. In this review, we have analysed 36 recent marine CPIAs and focused on their methodological approaches. We were especially interested in uncovering methodological similarities, identifying best practices and analysing whether the CPIAs have addressed the recent criticism. The review results showed surprisingly similar methodological approaches in >50% of the studies, raising hopes for finding coherence in international assessment efforts. Although the CPIA methods showed relatively few innovative approaches for addressing the major caveats of previous CPIAs, the most recent studies indicate that improved approaches may be soon found.

    Global healthcare practice has expanded in the past 20 years. At the same time the incorporation of research into the design process has gained prominence as a best practice among architects. The authors of this study investigated the status of design research in a variety of international settings. We intended to answer the question, "how pervasive is healthcare design research outside of the United States?" The authors reviewed the international literature on the design of healthcare facilities. More than 500 international studies and conference proceedings were incorporated in this literature review. A team of five research assistants searched multiple databases comparing approximately 16 keywords to geographic location. Some of those keywords included: evidence-based design, salutogenic design, design research, and healthcare environment. Additional articles were gathered by contacting prominent researchers and asking for their personal assessment of local health design research studies. While there are design researchers in most parts of the world, the majority of studies focus on the needs of populations in developed countries and generate guidelines that have significant cost and cultural implications that prohibit their implementation in developing countries. Additionally, the body of literature discussing the role of culture in healthcare environments is extremely limited. Design researchers must address the cultural implications of their studies. Additionally, we need to expand our research objectives to address healthcare design in countries that have not been previous considered. © 2014 Vendome Group, LLC.

  13. Long range global warming

    1995-01-01

    This paper explores one of the causes of global warming that is often overlooked, the direct heating of the environment by engineering systems. Most research and studies of global warming concentrate on the modification that is occurring to atmospheric air as a result of pollution gases being added by various systems; i.e., refrigerants, nitrogen oxides, ozone, hydrocarbons, halon, and others. This modification affects the thermal radiation balance between earth, sun and space, resulting in a decrease of radiation outflow and a slow rise in the earth's steady state temperature. For this reason the solution to the problem is perceived as one of cleaning up the processes and effluents that are discharged into the environment. In this paper arguments are presented that suggest, that there is a far more serious cause for global warming that will manifest itself in the next two or three centuries; direct heating from the exponential growth of energy usage by humankind. Because this is a minor contributor to the global warming problem at present, it is overlooked or ignored. Energy use from the combustion of fuels and from the output of nuclear reactions eventually is manifest as warming of the surroundings. Thus, as energy is used at an ever increasing rate the consequent global warming also increases at an ever increasing rate. Eventually this rate will become equal to a few percent of solar radiation. When this happens the earth's temperature will have risen by several degrees with catastrophic results. The trends in world energy use are reviewed and some mathematical models are presented to suggest future scenarios. These models can be used to predict when the global warming problem will become undeniably apparent, when it will become critical, and when it will become catastrophic

    Full Text Available Communication within organisations in a global environment requires effective internal and strategic planning at the executive level. Previous studies indicate that measurement is a key factor in assessing the needs and success of global communication within an organisation. Survey questions were used to measure satisfaction responses from 650 local and 110 global employees in a technology division of a large manufacturing company. In this case study, employees expressed the need to connect team members through face-to-face meetings, employee webcast meetings, web chat forums, and an updated employee networking site. The findings formed the foundations for recommendations for strategy, objectives, and tactics within the organisation.

    1994-01-01

    Global environmental policy has hardly made headway after the United Nations World Conference on Environment and Development (UNCED) in Rio in June 1992, despite there being no shortage of programmes, institutions, and actors. Obviously, formal structures for political action based on the system of institutions of the United Nations do not suffice. Global environmental policy strategies must reach further, overcoming system-immanent obstacles to sustainable development. This necessitates analyzing the causes of environmental destruction and making a critical evaluation of the relations between the societies of the North and South that received their imprint from development policies. Only after such a preliminary elucidation by interdisciplinary approaches in the light of political and ecological economy and human ecology does an empirical analysis of politically controlled processes in environmental and development policy make sense. The analysis points to strategies for this international political field that rely on non-governmental actors and social movements, and question the traditional European model of an environmental policy determined by government institutions.

  19. Global hierarchical classification of deepwater and wetland environments from remote sensing products

    Global surface water maps have improved in spatial and temporal resolutions through various remote sensing methods: open water extents with compiled Landsat archives and inundation with topographically downscaled multi-sensor retrievals. These time-series capture variations through time of open water and inundation without discriminating between hydrographic features (e.g. lakes, reservoirs, river channels and wetland types) as other databases have done as static representation. Available data sources present the opportunity to generate a comprehensive map and typology of aquatic environments (deepwater and wetlands) that improves on earlier digitized inventories and maps. The challenge of classifying surface waters globally is to distinguishing wetland types with meaningful characteristics or proxies (hydrology, water chemistry, soils, vegetation) while accommodating limitations of remote sensing data. We present a new wetland classification scheme designed for global application and produce a map of aquatic ecosystem types globally using state-of-the-art remote sensing products. Our classification scheme combines open water extent and expands it with downscaled multi-sensor inundation data to capture the maximal vegetated wetland extent. The hierarchical structure of the classification is modified from the Cowardin Systems (1979) developed for the USA. The first level classification is based on a combination of landscape positions and water source (e.g. lacustrine, riverine, palustrine, coastal and artificial) while the second level represents the hydrologic regime (e.g. perennial, seasonal, intermittent and waterlogged). Class-specific descriptors can further detail the wetland types with soils and vegetation cover. Our globally consistent nomenclature and top-down mapping allows for direct comparison across biogeographic regions, to upscale biogeochemical fluxes as well as other landscape level functions.

  20. Geographical spread of global emissions: Within-country inequalities are large and increasing

    2016-01-01

    In spite of the extensive literature on greenhouse gas emission inequalities at the world-wide level, most of the evidence so far has been based on country-level data. However, the within-country dimension matters for both the implementation and the policy formation of climate policies. As a preliminary step towards a better understanding of within-country inequalities, this paper measures their extent for the two major greenhouse gases, CO_2 and CH_4, over the 1970–2008 period. Using Theil-index decompositions, we show that within-country inequalities account for the bulk of global inequality, and tend to increase over the sample period, in contrast with diminishing between-country inequalities. Including differences across sectors reveals that between-sector inequalities matter more than between-country inequalities, and between-sector inequalities become the dominant source of global inequality at the end of the sample period in the CO_2 case. Finally, estimated social tensions arising from the disconnection between emissions and future damages turn out to be increasing as soon as within-country disparities are taken into account. These orders of magnitude should be kept in mind while discussing the efficiency and fairness of alternative paths in combating global warming. - Highlights: • We estimate global spatial CO_2 and CH_4 inequality using grid data for 1970–2008. • Overall spatial emission inequality is constant for CO_2 and increasing for CH_4. • Within-country inequality is rising and constitutes the main bulk of overall inequality. • An important part of within country inequality is due to differences among sectors. • The gap between emitters and victims is rising within countries.

    2009-03-01

    Full Text Available Ubiquitous learning allows students to learn at any time and any place. Adaptivity plays an important role in ubiquitous learning, aiming at providing students with adaptive and personalized learning material, activities, and information at the right place and the right time. However, for providing rich adaptivity, the student model needs to be able to gather a variety of information about the students. In this paper, an automatic, global, and dynamic student modeling approach is introduced, which aims at identifying and frequently updating information about students’ progress, learning styles, interests and knowledge level, problem solving abilities, preferences for using the system, social connectivity, and current location. This information is gathered in an automatic way, using students’ behavior and actions in different learning situations provided by different components/services of the ubiquitous learning environment. By providing a comprehensive student model, students can be supported by rich adaptivity in every component/service of the learning environment. Furthermore, the information in the student model can help in giving teachers a better understanding about the students’ learning process.

  5. Metagenomes Reveal Global Distribution of Bacterial Steroid Catabolism in Natural, Engineered, and Host Environments

    Directory of Open Access Journals (Sweden)

    2018-01-01

    Full Text Available Steroids are abundant growth substrates for bacteria in natural, engineered, and host-associated environments. This study analyzed the distribution of the aerobic 9,10-seco steroid degradation pathway in 346 publically available metagenomes from diverse environments. Our results show that steroid-degrading bacteria are globally distributed and prevalent in particular environments, such as wastewater treatment plants, soil, plant rhizospheres, and the marine environment, including marine sponges. Genomic signature-based sequence binning recovered 45 metagenome-assembled genomes containing a majority of 9,10-seco pathway genes. Only Actinobacteria and Proteobacteria were identified as steroid degraders, but we identified several alpha- and gammaproteobacterial lineages not previously known to degrade steroids. Actino- and proteobacterial steroid degraders coexisted in wastewater, while soil and rhizosphere samples contained mostly actinobacterial ones. Actinobacterial steroid degraders were found in deep ocean samples, while mostly alpha- and gammaproteobacterial ones were found in other marine samples, including sponges. Isolation of steroid-degrading bacteria from sponges confirmed their presence. Phylogenetic analysis of key steroid degradation proteins suggested their biochemical novelty in genomes from sponges and other environments. This study shows that the ecological significance as well as taxonomic and biochemical diversity of bacterial steroid degradation has so far been largely underestimated, especially in the marine environment.

  10. Unrealized Global Temperature Increase: Implications of Current Uncertainties

    Science.gov (United States)

    Schwartz, Stephen E.

    2018-04-01

    Unrealized increase in global mean surface air temperature (GMST) may result from the climate system not being in steady state with forcings and/or from cessation of negative aerosol forcing that would result from decreases in emissions. An observation-constrained method is applied to infer the dependence of Earth's climate sensitivity on forcing by anthropogenic aerosols within the uncertainty on that forcing given by the Fifth (2013) Assessment Report of the Intergovernmental Panel on Climate Change. Within these uncertainty ranges the increase in GMST due to temperature lag for future forcings held constant is slight (0.09-0.19 K over 20 years; 0.12-0.26 K over 100 years). However, the incremental increase in GMST that would result from a hypothetical abrupt cessation of sources of aerosols could be quite large but is highly uncertain, 0.1-1.3 K over 20 years. Decrease in CO2 abundance and forcing following abrupt cessation of emissions would offset these increases in GMST over 100 years by as little as 0.09 K to as much as 0.8 K. The uncertainties quantified here greatly limit confidence in projections of change in GMST that would result from any strategy for future reduction of emissions.

  11. The strategic role of partnerships between universities and private corporations as a driver for increasing workforce competitiveness in a global economy

    Directory of Open Access Journals (Sweden)

    Damoc Adrian-Ioan

    2017-07-01

    Full Text Available A global economic context means increased competition as corporations face contenders from other countries, and there is a wider range of choices on the market available to consumers. This global competition drives economic actors to seek competitive edges to increase the efficiency of their operations; within this global economy, corporations seek these advantages, outsourcing their activities in order to make use of the opportunities of globalisation. The same situation can be encountered on the labour market. While the expansion of economic activities globally often means increased employment opportunities, it also means that job seekers from around the world need to become more competitive on the job market to attract better employment opportunities. Workforce competitiveness is determined by various factors, like availability and ease of access (i.e. job market legislation, level and quality of education, and cost. The level and quality of education are of particular concern, as it gauges the potential of the workforce, and is the cornerstone of the controversial “skills gap”, based on a common complaint of corporations regarding a shortage of skilled employees. Acknowledging the importance of this factor, numerous companies have concluded partnerships with local universities, leading to intimate connections between the business environment and education. Thus, in the same manner that supply and demand shape the markets for typical goods and determine the success of a market, these partnerships between universities and corporations influence the labour market, bringing together demand (i.e. the corporations seeking skilled employees and supply (universities and education centres training the future workforce. There are numerous long-term benefits that such partnerships can bring to a country’s education sector. As such, the present paper seeks to examine the strategic importance of partnerships between academia and industry as a key

    Understanding the spatiotemporal change trend of global crop growth and multiple cropping system under climate change scenarios is a critical requirement for supporting the food security issue that maintains the function of human society. Many studies have predicted the effects of climate changes on crop production using a combination of filed studies and models, but there has been limited evidence relating decadal-scale climate change to global crop growth and the spatiotemporal distribution of multiple cropping system. Using long-term satellite-derived Normalized Difference Vegetation Index (NDVI) and observed climate data from 1982 to 2012, we investigated the crop growth trend, spatiotemporal pattern trend of agricultural cropping intensity, and their potential correlations with respect to the climate change drivers at a global scale. Results show that 82.97 % of global cropland maximum NDVI witnesses an increased trend while 17.03 % of that shows a decreased trend over the past three decades. The spatial distribution of multiple cropping system is observed to expand from lower latitude to higher latitude, and the increased cropping intensity is also witnessed globally. In terms of regional major crop zones, results show that all nine selected zones have an obvious upward trend of crop maximum NDVI (p impact on the crop growth trend.

    The 'green paradox' by Hans-Werner Sinn suggests that increasing resource taxes accelerate global warming because resource owners increase near-term extraction in fear of higher future taxation. In this note we show that this effect does only occur for the specific set of carbon taxes that increase at a rate higher than the effective discount rate of the resource owners. We calculate a critical initial value for the carbon tax that leads to a decreased cumulative consumption over the entire (infinite) time horizon. Applying our formal findings to carbon taxes for several mitigation targets, we conclude that there is a low risk of a green paradox in case the regulator implements and commits to a permanently mal-adjusted tax. This remaining risk can be avoided by emissions trading scheme as suggested by Sinn-as long as the emission caps are set appropriately and the intertemporal permit market works correctly. - Research highlights: {yields} Fast increasing carbon taxes accelerate global warming if they start at a low level. {yields} Appropriately high carbon taxes can always reduce cumulative emissions. {yields} Many existing tax proposals are unlikely to accelerate global warming. {yields} Capital income taxes cannot reduce cumulative emissions.

    A series of major scientific programs carried out over the past 40 years has greatly increased understanding of our global environment and has led to the present concern over global change. Each program responded to a specific and urgent scientific need or opportunity. In each case, institutions and resources were created that provided the foundation for later programs. Increased scientific understanding has exposed threats to future welfare and has raised serious policy implications for governments. Institutions for responding to global policy issues need to be created or strengthened. Recommendations for better procedures and institutional structures are provided in this article. 39 refs

    We provide an overview of contemporaneous global mangrove soil organic carbon (SOC) estimates, focusing on a framework to explain disproportionate differences among observed data as a way to improve global estimates. This framework is based on a former conceptual model, the coastal environmental setting, in contrast to the more popular latitude-based hypotheses largely believed to explain hemispheric variation in mangrove ecosystem properties. To demonstrate how local and regional estimates of SOC linked to coastal environmental settings can render more realistic global mangrove SOC extrapolations we combined published and unpublished data, yielding a total of 106 studies, reporting on 552 sites from 43 countries. These sites were classified into distinct coastal environmental setting types according to two concurrent worldwide typology of nearshore coastal systems classifications. Mangrove SOC density varied substantially across coastal environmental settings, ranging from 14.9 ± 0.8 in river dominated (deltaic) soils to 53.9 ± 1.6 mg cm-3 (mean ± SE) in karstic coastlines. Our findings reveal striking differences between published values and contemporary global mangrove SOC extrapolation based on country-level mean reference values, particularly for karstic-dominated coastlines where mangrove SOC stocks have been underestimated by up to 50%. Correspondingly, climate-based global estimates predicted lower mangrove SOC density values (32-41 mg C cm-3) for mangroves in karstic environments, differing from published (21-126 mg C cm-3) and unpublished (47-58 mg C cm-3) values. Moreover, climate-based projections yielded higher SOC density values (27-70 mg C cm-3) for river-dominated mangroves compared to lower ranges reported in the literature (11-24 mg C cm-3). We argue that this inconsistent reporting of SOC stock estimates between river-dominated and karstic coastal environmental settings is likely due to the omission of geomorphological and geophysical

    2018-04-01

    Full Text Available Understanding the spatiotemporal change trend of global crop growth and multiple cropping system under climate change scenarios is a critical requirement for supporting the food security issue that maintains the function of human society. Many studies have predicted the effects of climate changes on crop production using a combination of filed studies and models, but there has been limited evidence relating decadal-scale climate change to global crop growth and the spatiotemporal distribution of multiple cropping system. Using long-term satellite-derived Normalized Difference Vegetation Index (NDVI and observed climate data from 1982 to 2012, we investigated the crop growth trend, spatiotemporal pattern trend of agricultural cropping intensity, and their potential correlations with respect to the climate change drivers at a global scale. Results show that 82.97 % of global cropland maximum NDVI witnesses an increased trend while 17.03 % of that shows a decreased trend over the past three decades. The spatial distribution of multiple cropping system is observed to expand from lower latitude to higher latitude, and the increased cropping intensity is also witnessed globally. In terms of regional major crop zones, results show that all nine selected zones have an obvious upward trend of crop maximum NDVI (p < 0.001, and as for climatic drivers, the gradual temperature and precipitation changes have had a measurable impact on the crop growth trend.

    Hartmann, Dennis L.

    Enough coal exists to sustain world energy consumption growth through at least the end of the next century. If fossil carbon fuel consumption continues to increase at current rates, however, atmospheric carbon dioxide concentrations will likely more than double, probably leading to significant warming of global climate, shifts in regional climates, and sea-level rise. Scientists and citizens throughout the world are discussing what should be done about the effects of our energy economy on the global environment.The issue is very broad and engaging, ranging from basic issues of geoscience to economics to fundamental value systems, and it has mobilized great economic interests and concern for our global environment. We live in an interesting time when human activities have begun to compete with the global capacities of Earth to recycle the elements of life. In the coming years, we will see how the world community reacts to this challenge, and what combination of conservation, technological development, and adaptation is ultimately adopted.

  7. Dialogical Self Theory and the increasing multiplicity of I-positions in a globalizing society: an introduction.

    Science.gov (United States)

    Hermans, Hubert J M

    2012-01-01

    Dialogical Self Theory is a recent development in the social sciences, based on a conception of the self as a society of mind. In this conception, the self is considered as extended to significant others in the environment, who populate the self as a dynamic multiplicity of I-positions between which dialogical or monological relationships may emerge. While from a spatial perspective the self is engaged in a process of positioning and counterpositioning in a globalizing society, from a temporal point of view the self is part of a process of positioning and repositioning in collective history and personal development. Some phenomena that are necessary for the understanding of the dialogical self are discussed: dominance and social power, the processes of globalization and localization, the experience of uncertainty and possible reactions to uncertainty in a globalizing world. Finally, the different contributions of this special issue are placed in the context of the presented conceptual framework. Copyright © 2012 Wiley Periodicals, Inc., A Wiley Company.

    Russia and Ukraine are countries with relatively large untapped agricultural potentials, both in terms of abandoned agricultural land and substantial yield gaps. Here we present a comprehensive assessment of Russian and Ukrainian crop production potentials and we analyze possible impacts of their future utilization, on a regional as well as global scale. To this end, the total amount of available abandoned land and potential yields in Russia and Ukraine are estimated and explicitly implemented in an economic agricultural sector model. We find that cereal (barley, corn, and wheat) production in Russia and Ukraine could increase by up to 64% in 2030 to 267 million tons, compared to a baseline scenario. Oilseeds (rapeseed, soybean, and sunflower) production could increase by 84% to 50 million tons, respectively. In comparison to the baseline, common net exports of Ukraine and Russia could increase by up to 86.3 million tons of cereals and 18.9 million tons of oilseeds in 2030, representing 4% and 3.6% of the global production of these crops, respectively. Furthermore, we find that production potentials due to intensification are ten times larger than potentials due to recultivation of abandoned land. Consequently, we also find stronger impacts from intensification at the global scale. A utilization of crop production potentials in Russia and Ukraine could globally save up to 21 million hectares of cropland and reduce average global crop prices by more than 3%.

    The effects of global mitochondrial calcium (Ca 2+ ) uniporter (MCU) deficiency on hypoxic-ischemic (HI) brain injury, neuronal Ca 2+ handling, bioenergetics and hypoxic preconditioning (HPC) were examined. Forebrain mitochondria isolated from global MCU nulls displayed markedly reduced Ca 2+ uptake and Ca 2+ -induced opening of the membrane permeability transition pore. Despite evidence that these effects should be neuroprotective, global MCU nulls and wild-type (WT) mice suffered comparable HI brain damage. Energetic stress enhanced glycolysis and depressed Complex I activity in global MCU null, relative to WT, cortical neurons. HI reduced forebrain NADH levels more in global MCU nulls than WT mice suggesting that increased glycolytic consumption of NADH suppressed Complex I activity. Compared to WT neurons, pyruvate dehydrogenase (PDH) was hyper-phosphorylated in MCU nulls at several sites that lower the supply of substrates for the tricarboxylic acid cycle. Elevation of cytosolic Ca 2+ with glutamate or ionomycin decreased PDH phosphorylation in MCU null neurons suggesting the use of alternative mitochondrial Ca 2+ transport. Under basal conditions, global MCU nulls showed similar increases of Ca 2+ handling genes in the hippocampus as WT mice subjected to HPC. We propose that long-term adaptations, common to HPC, in global MCU nulls compromise resistance to HI brain injury and disrupt HPC.

  10. From the Collaborative Environment of the Remote Laboratory NetLab to the Global Collaboration

    2008-07-01

    Full Text Available The remote laboratory (RL can be considered as a modern collaborative learning environment, where students acquire skills required for efficient collaboration and communication on a local and global scale, both today and in the near future. The majority of current existing RLs are not constructed to allow the involved participants to collaborate in real time. This paper describes the collaborative RL NetLab, developed at the University of South Australia (UniSA, which allows up to three onshore and/or offshore students to conduct remote experiments at the same time as a team. This allows the online RL environment to become very similar, if not nearly identical to its real laboratory counterpart. The collaboration in the real laboratory is replaced by the “global” on-line collaboration.

    Following the Chernobyl accident in 1986, a group of experts from the World Health Organization (WHO) and the United Nations Environment Program (UNEP) met in France to discuss and develop the basic principles of a global environmental radiation monitoring network (GERMON). The basic functions of this network were to provide regular reports on environmental radiation levels and to be in a position to provide reliable and accurate radiation measurements on a quick and accurate radiation measurements on a quick turnaround basis in the event of a major radiation release. By 1992, although 58 countries had indicated an interest in becoming a part of the GERMON system, only 16 were providing data on a regular basis. This paper traces the history of GERMON from its inception in 1987 through its activities during 1993-4. It details the objectives of the network, describes functions, lists its participants, and presents obstacles in the current network. The paper examines the data requirements for radiological emergency preparedness and offers suggestions for the current system. The paper also describes the growing need for such a network. To add a domestic perspective, the authors present a summary of the environmental monitoring information system that was used by the NRC in 1986 in its analyses of the Chernobyl incident. Then we will use this 1986 experience to propose a method for the use of GERMON should a similar occasion arise in the future

    2007-01-01

    Since the beginning of the 19th century humans have increasingly fixed atmospheric nitrogen as ammonia to be used as fertilizer. The fertilizers are necessary to create amino acids and carbohydrates in plants to feed animals and humans. The efficiency with which the fertilizers eventually reach humans is very small: 5-15%, with much of the remainder lost to the environment. The global industrial production of ammonia amounts to 117 Mton NH 3 -N year -1 (for 2004). By comparison, we calculate that anthropogenic emissions of NH 3 to the atmosphere over the lifecycle of industrial NH 3 in agriculture are 45.3 Mton NH 3 -N year -1 , about half the industrial production. Once emitted ammonia has a central role in many environmental issues. We expect an increase in fertilizer use through increasing demands for food and biofuels as population increases. Therefore, management of ammonia or abatement is necessary. - Half of industrial ammonia production is eventually lost to the global environment with significant effects

    1994-01-01

    In spring 1992, increasingly concerned about the preservation of the natural basis for the life and development of humanity, the Federal Government of Germany established the German Advisory Council on Global Change. In its 1993 Annual Report, the Council endeavours to provide a holistic analysis of the Earth System, whereby the central focus is directed at the principal interactions between nature and society. The aim here is to demonstrate the complexity of environmental problems, on the one hand, and to create, on the other, the analytical basis for assessing the impact of current trends (increased greenhouse effect, declining biodiversity, loss of fertile soils, population growth, etc.) on the system as a whole. In-depth treatment of core topics will be related back continually to this global perspective, and vice versa, in order to contribute towards continuous improvement of our understanding of the system. The Report begins with a circumscription of its subject, i.e. a definition of what is meant by ''global environmental change''. This leads inevitably to the issue of ''sustainable development'', which will be dealt with in one of the Reports to follow. The highly condensed description of the ecosphere and the anthroposphere, and an analysis of the linkages between the two spheres in the Earth System, is followed by the examination of the main components and the relevant trends of global environmental change.

    Enhancing competitiveness in the global airline industry is at the forefront of attention with airlines, government, and the flying public. The seemingly unchecked growth of major airline alliances is heralded as an enhancement to global competition. However, like many mega-conglomerates, mega-airlines will face complications driven by size regardless of the many recitations of enhanced efficiency. Outlined herein is a conceptual model to serve as a decision tool for policy-makers, managers, and consumers of airline services. This model is developed using public data for the United States (U.S.) major airline industry available from the U/S. Department of Transportation, Federal Aviation Administration, the National Aeronautics and Space Administration, the National Transportation Safety Board, and other public and private sector sources. Data points include number of accidents, pilot deviations, operational performance indicators, flight problems, and other factors. Data from these sources provide opportunity to develop a model based on a complex dot product equation of two vectors. A row vector is weighted for importance by a key informant panel of government, industry, and consumer experts, while a column vector is established with the factor value. The resulting equation, known as the national Airline Quality Rating (AQR), where Q is quality, C is weight, and V is the value of the variables, is stated Q=C[i1-19] x V[i1-19]. Looking at historical patterns of AQR results provides the basis for establishment of an industry benchmark for the purpose of enhancing airline operational performance. A 7 year average of overall operational performance provides the resulting benchmark indicator. Applications from this example can be applied to the many competitive environments of the global industry and assist policy-makers faced with rapidly changing regulatory challenges.

    Diets link environmental and human health. Rising incomes and urbanization are driving a global dietary transition in which traditional diets are replaced by diets higher in refined sugars, refined fats, oils and meats. By 2050 these dietary trends, if unchecked, would be a major contributor to an estimated 80 per cent increase in global agricultural greenhouse gas emissions from food production and to global land clearing. Moreover, these dietary shifts are greatly increasing the incidence of type II diabetes, coronary heart disease and other chronic non-communicable diseases that lower global life expectancies. Alternative diets that offer substantial health benefits could, if widely adopted, reduce global agricultural greenhouse gas emissions, reduce land clearing and resultant species extinctions, and help prevent such diet-related chronic non-communicable diseases. The implementation of dietary solutions to the tightly linked diet-environment-health trilemma is a global challenge, and opportunity, of great environmental and public health importance.

    Lightning plays an important role in atmospheric chemistry and in the initiation of wildfires, but the impact of global warming on lightning rates is poorly constrained. The lightning flash rate is proposed here to be proportional to the convective available potential energy (CAPE) times the precipitation rate. Using observations, the product of CAPE and precipitation is found to explain the majority of variance in the time series of total cloud-to-ground lightning flashes over the contiguous United States (CONUS) on timescales ranging from diurnal to seasonal. The observations reveal that storms convert the CAPE of water mass to discharged lightning energy with an efficiency of about 1%. This proxy can be applied to global climate models, which provide predictions for the increase in lightning due to global warming. Results from 11 GCMs will be shown.

    This paper explains the involvement of the global environment action plan of Japan Society of Civil Engineers, Agenda 21, with civil engineerings and global environmental problems, as well as the global environment action plan. Global environmental problems require handling the matters in three ways: identification and elucidation of events, effect analysis estimation, and alleviation, avoidance and prevention of the effect. Settlement and proliferation of civil engineering technologies transferred to developing countries demand indispensably understanding such features of the developing countries as social and economic conditions, natural conditions, climates, histories, races, and cultures. Realizing the sustainable development requires the followings: formation of civil engineerings that contribute to improving global environments; development of civil engineerings that make coexistence of human being and other living organisms possible; analyses of effects and mechanisms of global warming and weather change and the corresponding technique and system development; and development of techniques to build resource circulating type national land and cities. It is also essential to move forward positively structuring civil engineerings that contribute to solving such global environmental problems as acid rains and marine pollution, and technical development thereof; providing guidelines on execution of international civil engineering constructions, and technical development thereof; developing civil engineerings in developing countries and assisting training of people.

    Global environmental policy has hardly made headway after the United Nations World Conference on Environment and Development (UNCED) in Rio in June 1992, despite there being no shortage of programmes, institutions, and actors. Obviously, formal structures for political action based on the system of institutions of the United Nations do not suffice. Global environmental policy strategies must reach further, overcoming system-immanent obstacles to sustainable development. This necessitates analyzing the causes of environmental destruction and making a critical evaluation of the relations between the societies of the North and South that received their imprint from development policies. Only after such a preliminary elucidation by interdisciplinary approaches in the light of political and ecological economy and human ecology does an empirical analysis of politically controlled processes in environmental and development policy make sense. The analysis points to strategies for this international political field that rely on non-governmental actors and social movements, and question the traditional European model of an environmental policy determined by government institutions.

The second volume of ''Adaptation and Evolution in Marine Environments - The Impacts of Global Change on Biodiversity'' from the series ''From Pole to Pole'' integrates the marine biology contribution of the first tome to the IPY 2007-2009, presenting overviews of organisms (from bacteria and ciliates to higher vertebrates) thriving on polar continental shelves, slopes and deep sea. The speed and extent of warming in the Arctic and in regions of Antarctica (the Peninsula, at the present) are greater than elsewhere. Changes impact several parameters, in particular the extent of sea ice; organisms, ecosystems and communities that became finely adapted to increasing cold in the course of millions of years are now becoming vulnerable, and biodiversity is threatened. Investigating evolutionary adaptations helps to foresee the impact of changes in temperate areas, highlighting the invaluable contribution of polar marine research to present and future outcomes of the IPY in the Earth system scenario.

    The GEF remains the interim operating entity of the financial mechanism, the aid provider, for the Climate Change Convention (FCCC); It had 1.6 billion dollars to spend between 1994 and 1997 on the 'incremental costs' of implementing UN environmental conventions in eligible countries. The paper describes how this multilateral fund has functioned so far in the energy-environment arena, analyzing its governance and policies, decision-making criteria, project cycle and strategies for monitoring and evaluation. Through the patterns of GEF assistance to climate change related science, technologies and institutions, we explore the origins and wider purposes of the entity and in the process illuminate some assumptions and principles underlying the work of the GEF Secretariat and associated bureaucracies. What can realistically be expected should GEF become a more permanent fund for 'global environmental benefits' after current negotiations for its second replenishment? (author)

    The purpose of this report is to describe the current state of knowledge regarding the sources and quantities of heavy metal emissions, their transport and fate, their potential health and environmental effects, and strategies to control them. The approach is to review the literature on this topic and to consult with experts in the field. Ongoing research activities and research needs are discussed. Estimates of global anthropogenic and natural emissions indicate that anthropogenic emissions are responsible for most of the heavy metals released into the atmosphere and that industrial activities have had a significant impact on the global cycling of trace metals. The largest anthropogenic sources of trace metals are coal combustion and the nonferrous metal industry. Atmospheric deposition is an important pathway by which trace metals enter the environment. Atmospheric deposition varies according to the solubility of the element and the length of time it resides in the atmosphere. Evidence suggests that deposition is influenced by other chemicals in the atmosphere, such as ozone and sulfur dioxide. Trace metals also enter the environment through leaching. Existing emissions-control technologies such as electrostatic precipitators, baghouses, and scrubbers are designed to remove other particulates from the flue gas of coal-fired power plants and are only partially effective at removing heavy metals. Emerging technologies such as flue gas desulfurization, lignite coke, and fluidized bed combustion could further reduce emissions. 108 refs

  11. Hypercompetitive Environments: An Agent-based model approach

    Dias, Manuel; Araújo, Tanya

    Information technology (IT) environments are characterized by complex changes and rapid evolution. Globalization and the spread of technological innovation have increased the need for new strategic information resources, both from individual firms and management environments. Improvements in multidisciplinary methods and, particularly, the availability of powerful computational tools, are giving researchers an increasing opportunity to investigate management environments in their true complex nature. The adoption of a complex systems approach allows for modeling business strategies from a bottom-up perspective — understood as resulting from repeated and local interaction of economic agents — without disregarding the consequences of the business strategies themselves to individual behavior of enterprises, emergence of interaction patterns between firms and management environments. Agent-based models are at the leading approach of this attempt.

  13. Autism and increased paternal age related changes in global levels of gene expression regulation.

    Directory of Open Access Journals (Sweden)

    Full Text Available A causal role of mutations in multiple general transcription factors in neurodevelopmental disorders including autism suggested that alterations in global levels of gene expression regulation might also relate to disease risk in sporadic cases of autism. This premise can be tested by evaluating for changes in the overall distribution of gene expression levels. For instance, in mice, variability in hippocampal-dependent behaviors was associated with variability in the pattern of the overall distribution of gene expression levels, as assessed by variance in the distribution of gene expression levels in the hippocampus. We hypothesized that a similar change in variance might be found in children with autism. Gene expression microarrays covering greater than 47,000 unique RNA transcripts were done on RNA from peripheral blood lymphocytes (PBL of children with autism (n = 82 and controls (n = 64. Variance in the distribution of gene expression levels from each microarray was compared between groups of children. Also tested was whether a risk factor for autism, increased paternal age, was associated with variance. A decrease in the variance in the distribution of gene expression levels in PBL was associated with the diagnosis of autism and a risk factor for autism, increased paternal age. Traditional approaches to microarray analysis of gene expression suggested a possible mechanism for decreased variance in gene expression. Gene expression pathways involved in transcriptional regulation were down-regulated in the blood of children with autism and children of older fathers. Thus, results from global and gene specific approaches to studying microarray data were complimentary and supported the hypothesis that alterations at the global level of gene expression regulation are related to autism and increased paternal age. Global regulation of transcription, thus, represents a possible point of convergence for multiple etiologies of autism and other

    Human activities such as burning of fossil fuels play a role in upsetting a previously more balanced and harmonious ecosystem. Climate change-a significant variation in the usual pattern of Earth's average weather conditions is a product of this ecosystem imbalance, and the rise in the Earth's average temperature (global warming) is a prominent evidence. There is a correlation between global warming and the ease of transmission of infectious diseases. Therefore, with global health in focus, we herein opine a stepping-up of research activities regarding global warming and infectious diseases globally.

    The 2008 global economic crisis appears to have triggered an increase in suicides, particularly among men in Europe and America. To investigate the impact of the economic crisis on international trends in suicide, researchers conducted an analysis comparing the number of suicides in 2009 with the number that would have been expected based on trends before the crisis (2000-2007). The analysis included data from 54 countries.

  18. Greenhouse gases and global warming

    International Nuclear Information System (INIS)

    1995-01-01

    From previous articles we have learned about the complexities of our environment, its atmosphere and its climate system. we have also learned that climate change and, therefore global warm and cool periods are naturally occurring phenomena. Moreover, all scientific evidence suggests that global warming, are likely to occur again naturally in the future. However, we have not yet considered the role of the rates of climate change in affecting the biosphere. It appears that how quickly the climate changes may be more important than the change itself. In light of this concern, let us now consider the possibility that, is due to human activity. We may over the next century experience global warming at rates and magnitudes unparalleled in recent geologic history. The following questions are answered; What can we learn from past climates? What do we know about global climates over the past 100 years? What causes temperature change? What are the greenhouse gases? How much have concentration of greenhouse gases increased in recent years? Why are increases in concentrations of greenhouse of concern? What is the e nhanced greenhouse effect ? How can human activity impact the global climate? What are some reasons for increased concentrations of greenhouse gases? What are fossil fuel and how do they transform into greenhouse gases? Who are the biggest emitters of greenhouse gases? Why are canada per capita emissions of greenhouse gases relatively high? (Author)

    Full Text Available As educators in an increasingly global society, we realize that we need to train students-undergraduate and graduate-to live and work in a global environment. This idea is not a new one; scholars, administrators, and government officials have been promoting similar notions for several decades, especially since the advent of the Cold War. David Ward, president of the American Council on Education, emphasized at the 2003 annual meeting of the National Association of State Universities and Land Grant Colleges that international education can no longer be considered "business as usual." The concept that graduates must have cross-cultural knowledge and expertise -long recognized in the languages and humanities-has steadily gained support to become an important goal and a marker of achievement for many professional schools in the United States today.

  1. GLOBEC: Global Ocean Ecosystems Dynamics: A component of the US Global Change Research Program

    Science.gov (United States)

    1991-01-01

    GLOBEC (GLOBal ocean ECosystems dynamics) is a research initiative proposed by the oceanographic and fisheries communities to address the question of how changes in global environment are expected to affect the abundance and production of animals in the sea. The approach to this problem is to develop a fundamental understanding of the mechanisms that determine both the abundance of key marine animal populations and their variances in space and time. The assumption is that the physical environment is a major contributor to patterns of abundance and production of marine animals, in large part because the planktonic life stages typical of most marine animals are intrinsically at the mercy of the fluid motions of the medium in which they live. Consequently, the authors reason that a logical approach to predicting the potential impact of a globally changing environment is to understand how the physical environment, both directly and indirectly, contributes to animal abundance and its variability in marine ecosystems. The plans for this coordinated study of of the potential impact of global change on ocean ecosystems dynamics are discussed.

  4. Using animation quality metric to improve efficiency of global illumination computation for dynamic environments

    Science.gov (United States)

    Myszkowski, Karol; Tawara, Takehiro; Seidel, Hans-Peter

    2002-06-01

    In this paper, we consider applications of perception-based video quality metrics to improve the performance of global lighting computations for dynamic environments. For this purpose we extend the Visible Difference Predictor (VDP) developed by Daly to handle computer animations. We incorporate into the VDP the spatio-velocity CSF model developed by Kelly. The CSF model requires data on the velocity of moving patterns across the image plane. We use the 3D image warping technique to compensate for the camera motion, and we conservatively assume that the motion of animated objects (usually strong attractors of the visual attention) is fully compensated by the smooth pursuit eye motion. Our global illumination solution is based on stochastic photon tracing and takes advantage of temporal coherence of lighting distribution, by processing photons both in the spatial and temporal domains. The VDP is used to keep noise inherent in stochastic methods below the sensitivity level of the human observer. As a result a perceptually-consistent quality across all animation frames is obtained.

  6. Poor understanding? Challenges to Global Development Education

    Directory of Open Access Journals (Sweden)

    2018-03-01

    Full Text Available As members of a global community, we cohabit a metaphorically shrinking physical environment, and are increasingly connected one to another, and to the world, by ties of culture, economics, politics, communication and the like. Education is an essential component in addressing inequalities and injustices concerning global rights and responsibilities. The increasing multicultural nature of societies locally, enhanced access to distal information, and the work of charitable organisations worldwide are some of the factors that have contributed to the interest in, and need for, understanding global development education. The project on which this paper reports sought answers to the question: to what extent and in what ways can a semester-long subject enhance and extend teacher education students’ understandings of and responses to global inequalities and global development aid? In the course of the project, a continuum model emerged, as follows: Indifference or ignorance ➝ pity and charity ➝ partnership and development among equals. In particular, this paper reports on some of the challenges and obstacles that need to be addressed in order to enhance pre-service teachers’ understandings of global development education. The study, conducted in Australia, has implications for global development education in other developed nations.

    That the transport sector is among the fastest growing economic sectors in both developed and developing countries is no surprise. The movement of people and goods is an essential part of modern society, and unlike some other economic goods the demand for transport largely coupled to income, so that as people become wealthier they demand ever more transport. Despite their many advantages of personal choice, convenience, and flexibility, modern transportation systems are not without problems, notably those that affect the environment and quality of life. The poor, even hazardous, air quality in many cities is often largely attributed to motor vehicle use, while the transport sector globally contributes one quarter of the greenhouse gases emitted to the atmosphere each year. Unfortunately, the environmental consequences of thransportation choices - both local and global - are often overlooked when transport planning decisions are made. This book attempts to remedy that deficiency by providing a guide to technical experts and policy makers concerned with environmental polices for the transport sector. It offers a consistent analytical structure for examining the environmental aspects of transport choices; defines the key economic and environmental concepts used in good policy analysis; and gives information on technologies, environmental impacts, and cost effectiveness of various policy options. The book also describes international financial mechanisms that can be used to support sustainable transportation policies and programmes. (au)

    1992-01-01

    The risk of global warming is one of the most serious global environmental problems. It is due to the increase of greenhouse gases emissions, mainly because of the use of fossil fuels in the energy sector, particularly for electricity generation. At an international level, experts now agree that measures are to be taken to reduce this risk. In the energy sector, an improvement of energy efficiency and an increase of nuclear electricity generation are often presented as the best available solutions. Renewable energy sources are often presented as a solution with a negligible potential impact, and sometimes, hydro power is even forgotten, or its coasts and its potential impacts on local environment are presented as an obstacle to its positive contribution to the reduction of global warming risk. Without denying the positive impacts of other solutions, this paper explains the possibilities and the benefits of an increased use of hydroelectric power, when implemented with a minimum impact on local environment and with a synergistic effect with the rational use of generated energy, in order to have access to a sustainable development. 19 refs., 6 figs

    Teaching about global environmental issues is often reserved to courses in environmental and/or geoscience departments. Universities that do not have departments that fall into these categories may be missing out on educating both science and non-science students about these important and timely issues. Loyola University Maryland is a private Jesuit liberal arts University with no environmental or geoscience department and prior to 2008 had no courses that focused on the science of global environmental issues. Global Environment in a course offered by the Chemistry Department that fills this niche. The course is designed for a general non-science audience, though the course content is also appropriate for science students. The primary goal of the course is for students to learn the basics about how the Earth system works and how our changing climate is related to biodiversity, pollution, water availability and society. The course is designated a diversity course which is a course that fulfills the University's call "to prepare students … to pursue justice by making an action-oriented response to the needs of the world." All students at Loyola University Maryland are required to take one diversity course. For this class, the diversity focus is environmental justice which is brought into the course through lectures, discussions and student projects. By bringing societal impacts into a science course the students can better understand why the environment is important and our actions affect both ourselves and others. The course has also evolved over four iterations into a course that maximizes student involvement while minimizing student angst. One way that this is accomplished is by eliminating tests and substituting daily quizzes using a student response system (clickers). Clickers are also used to poll students and to review what information the students are retaining. Students are able to self-guide their own learning in the course by creating a portfolio

    Full Text Available This paper aims to analyze the interaction of leadership more pronounced due to globalization, the business world, can no longer ignore the powerful cultural aspects of leadership. In other words, there are differences between leadership styles considered acceptable in a national culture or another. Looking at different models of leadership and differences between cultural norms, we find that in this increasingly globalized world, begin to crystallize several converging trends. Thus, "global leadership" that leaders who act in a multicultural environment would be useful following attributes and skills: charisma, aptitude for teamwork, openness to change, interest in political and socio-economic life of other countries; ability to retain good relations with people of other cultures, adaptability to new situations, ability to work in a multicultural team, etc. Foundation skills training exceptional global leadership is built from childhood through socialization experiences that influence cultural patterns, and also are influenced by them. Early managerial responsibilities and experience gained in international projects do not create skills for leadership in international environment, but they develop. Consequently, global leaders must create multicultural communities, creating a culture that goes over the differences between people and contains certain "guiding signals"-values and attitudes - which can be easily understood by employees from different cultural groups. Thus, global leadership development program does not focus exclusively on understanding and acceptance of cultural diversity, but goes further, making the people realize they need a common organizational culture. Globalization requires many changes in the economy, communication, political structures, in all areas of personal and organizational-among them such essential processes of cultural convergence and diversification.

    Full Text Available Currently, internal IT organizations use outsourcing and offshore arrangements to achieve cost savings and gain access to new capabilities. It was found that suppliers’ personnel at the operational level can face challenges with internalizing their operations based on the agreed outsourcing practices and transferred responsibilities. This study gives voice to the supplier and studies the impact of offshore outsourcing operation development activities. The internal IT unit from Nokia Devices selectively outsourced global IT service activities and responsibilities to the IT supplier. The outsourced activities were implemented by offshore centers in India and China. It was found that the global selective outsourcing environment (GSOE did not provide a solution to all of their expectations, and new unexpected challenges occurred. Several practices, communication and information sharing, and behavior-related lessons learned items were identified. It was found that the GSOE operation needs to be developed and implemented in an agile and incremental manner, instead of a singular implementation approach. Also, the globally distributed teams’ group dynamics critically impacted on the teams’ ability to work. The lessons learned items and recommendations can be utilized by other companies during their mode-of-operation development.

    Since the winter of 2013–2014, California has experienced its most severe drought in recorded history, causing statewide water stress, severe economic loss and an extraordinary increase in wildfires. Identifying the effects of global warming on regional water cycle extremes, such as the ongoing drought in California, remains a challenge. Here we analyse large-ensemble and multi-model simulations that project the future of water cycle extremes in California as well as to understand those associations that pertain to changing climate oscillations under global warming. Both intense drought and excessive flooding are projected to increase by at least 50% towards the end of the twenty-first century; this projected increase in water cycle extremes is associated with a strengthened relation to El Niño and the Southern Oscillation (ENSO)—in particular, extreme El Niño and La Niña events that modulate California's climate not only through its warm and cold phases but also its precursor patterns.

    2012-01-01

    Full Text Available The development of the private sector, employers’ requirements of specific communication skills, the economic field division into numberless branches of activity – finance and banks, management, human resources, accounting, international relations, tourism – the presence of a certain literature in the field by means of translations, all such aspects represent grounded reasons for the existence of a global economic vocabulary in the Romanian language. Finding its origins in the structuralism philosophic principles and associated with the structuralism linguistic trends, economic language’s globalisation becomes obvious nowadays through the occurrence of a large number of linguistic borrowings. Classified into either needless or necessary borrowed lexical units, lexical units borrowed and completely or at all assimilated in the target language, such borrowings lay the foundation of what specialists in the field call corporate language. Considering that the total or partial lack of knowledge on such language can become a real barrier in achieving communication, this study aims at analysing the level to which such words are known by the employees in the business environments involved in economic international partnerships and in multinational organisations.

  4. Climate of the Arctic marine environment.

    Science.gov (United States)

    Walsh, John E

    2008-03-01

    The climate of the Arctic marine environment is characterized by strong seasonality in the incoming solar radiation and by tremendous spatial variations arising from a variety of surface types, including open ocean, sea ice, large islands, and proximity to major landmasses. Interannual and decadal-scale variations are prominent features of Arctic climate, complicating the distinction between natural and anthropogenically driven variations. Nevertheless, climate models consistently indicate that the Arctic is the most climatically sensitive region of the Northern Hemisphere, especially near the sea ice margins. The Arctic marine environment has shown changes over the past several decades, and these changes are part of a broader global warming that exceeds the range of natural variability over the past 1000 years. Record minima of sea ice coverage during the past few summers and increased melt from Greenland have important implications for the hydrographic regime of the Arctic marine environment. The recent changes in the atmosphere (temperature, precipitation, pressure), sea ice, and ocean appear to be a coordinated response to systematic variations of the large-scale atmospheric circulation, superimposed on a general warming that is likely associated with increasing greenhouse gases. The changes have been sufficiently large in some sectors (e.g., the Bering/Chukchi Seas) that consequences for marine ecosystems appear to be underway. Global climate models indicate an additional warming of several degrees Celsius in much of the Arctic marine environment by 2050. However, the warming is seasonal (largest in autumn and winter), spatially variable, and closely associated with further retreat of sea ice. Additional changes predicted for 2050 are a general decrease of sea level pressure (largest in the Bering sector) and an increase of precipitation. While predictions of changes in storminess cannot be made with confidence, the predicted reduction of sea ice cover will

    Plastic pollution in the ocean is a global concern; concentrations reach 580,000 pieces per km(2) and production is increasing exponentially. Although a large number of empirical studies provide emerging evidence of impacts to wildlife, there has been little systematic assessment of risk. We performed a spatial risk analysis using predicted debris distributions and ranges for 186 seabird species to model debris exposure. We adjusted the model using published data on plastic ingestion by seabirds. Eighty of 135 (59%) species with studies reported in the literature between 1962 and 2012 had ingested plastic, and, within those studies, on average 29% of individuals had plastic in their gut. Standardizing the data for time and species, we estimate the ingestion rate would reach 90% of individuals if these studies were conducted today. Using these results from the literature, we tuned our risk model and were able to capture 71% of the variation in plastic ingestion based on a model including exposure, time, study method, and body size. We used this tuned model to predict risk across seabird species at the global scale. The highest area of expected impact occurs at the Southern Ocean boundary in the Tasman Sea between Australia and New Zealand, which contrasts with previous work identifying this area as having low anthropogenic pressures and concentrations of marine debris. We predict that plastics ingestion is increasing in seabirds, that it will reach 99% of all species by 2050, and that effective waste management can reduce this threat.

  7. Historic and future increase in the global land area affected by monthly heat extremes

    2013-01-01

    Climatic warming of about 0.5 ° C in the global mean since the 1970s has strongly increased the occurrence-probability of heat extremes on monthly to seasonal time scales. For the 21st century, climate models predict more substantial warming. Here we show that the multi-model mean of the CMIP5 (Coupled Model Intercomparison Project) climate models accurately reproduces the evolution over time and spatial patterns of the historically observed increase in monthly heat extremes. For the near-term (i.e., by 2040), the models predict a robust, several-fold increase in the frequency of such heat extremes, irrespective of the emission scenario. However, mitigation can strongly reduce the number of heat extremes by the second half of the 21st century. Unmitigated climate change causes most (>50%) continental regions to move to a new climatic regime with the coldest summer months by the end of the century substantially hotter than the hottest experienced today. We show that the land fraction experiencing extreme heat as a function of global mean temperature follows a simple cumulative distribution function, which depends only on natural variability and the level of spatial heterogeneity in the warming.

    Global warming could accelerate the spread of invasive species to higher latitudes and intensify their effects on native species. Here, we report results of two years of field surveys along a latitudinal gradient (21°N to 31°N) in southern China, to determine the species structure of the invasive plant Alternanthera philoxeroides community. We also performed a replacement series experiment (mono and mixed) to evaluate the effects of elevated temperature on the competitiveness of A. philoxeroides with the native co-occurring species Digitaria sanguinalis. In the field survey, we found that the dominance of A. philoxeroides increased with increasing of latitude gradient while cover of D. sanguinalis decreased. In monospecific plantings, artificial warming reduced the length of D. sanguinalis roots. In mixed plantings, warming reduced both A. philoxeroides abundance and D. sanguinalis stem length when A. philoxeroides was more prevalent in the planting. Warming also significantly reduced D. sanguinalis biomass, but increased that of A. philoxeroides. In addition, elevated temperatures significantly reduced the relative yield (RY) of D. sanguinalis, particularly when A. philoxeroides was planted in higher proportion in the plot. These results suggest that the invasiveness of A. philoxeroides increased with increasing latitude, and that warming may increase the effectiveness of its interspecific competition with D. sanguinalis. Hence, under global warming conditions, the harm to native species from A. philoxeroides would increase at higher latitudes. Our findings are critical for predicting the invasiveness of alien species under climate change. Copyright © 2016 Elsevier B.V. All rights reserved.

    2003-01-01

    The third Global Environment Outlook (GEO-3) was published on the eve of the Johannesburg summit (autumn 2002). GEO-3 looked back thirty years and forward thirty years. A set of what-if scenarios was used to explore the ways our society can advance, including implications for environmental and social goals. Characteristically, GEO-3 examines in a relatively deep fashion how its global scenarios can be interpreted in the context of each of the world's regions. This brochure presents the pan-European elaboration of the four GEO-3 scenarios. It focusses on the scenarios proper and their impacts in environmental terms. The scenarios are: The Markets First scenario envisages a world in which market-driven developments converge on the currently prevailing values and expectations in industrialized countries; In a Policy First world, strong actions are undertaken by governments in an attempt to achieve specific social and environmental goals; The Security First scenario assumes a world full of large disparities, where inequality and conflict, brought about by socio-economic and environmental stresses, prevail: and Sustainability First pictures a world in which a new development paradigm emerges in response to the challenge of sustainability supported by new, more equitable values and institutions. The second section describes 'the pan-European tale of the four futures' in a predominantly qualitative manner. Section 3 presents a regionally differentiated examination of the environmental implications of the scenarios. Details on input material, assumptions and methodologies applied, and actual results, can be found in Chapter 4 of GEO-3 'Outlook 2002-32' and in the Technical Background Report on GEO-3 Scenario Work

    The global energy balance of a city involves numerous energy flows and is rather complex. It includes, among others, the absorbed solar radiation and the energy fuels on one hand, and the heat loss to the environment --- by radiation, convection and evaporation --- on the other hand. This balance generally results in a temperature in the town that is slightly higher than in the surrounding country. Using solar energy saves imported fuels on one hand, but increases the absorption of solar radiation on the other hand. Simple, steady state models are used to assess the change of heat released to the environment when replacing the use of classical fuels by solar powered plants, on both the global and city scale. The conclusion is that, in most cases, this will reduce the heat released to the environment. The exception is cooling, for which a good solar alternative does not exist today. (Author)

  14. Towards Increased Engagement of Geoscientists in Global Development Frameworks

    2016-04-01

    Geoscientists have the potential to make a significant contribution to tackling some of the major socio-environmental challenges of today, including extreme poverty, sustainable development, disaster risk reduction and climate change. This presentation explores the importance and social responsibility of geoscientists to engage in such work through understanding and supporting key global development frameworks. During 2015 the international community agreed three important agendas for change. Each framework relates to the intersection of environmental processes with human activities and behaviours, addressing significant challenges affecting society. The frameworks are (i) the UN Global Goals for Sustainable Development, (ii) the Sendai Framework for Disaster Risk Reduction 2015-2030, and (iii) subject to final confirmation at the time of writing, an agreement on climate change at the Paris Conference of the Parties - COP21. The UN Global Goals for Sustainable Development, for example, includes 17 goals aiming to end extreme poverty, fight inequality and ensure environmental sustainability. Specific goals relate to clean water and sanitation, clean and affordable energy, the development of resilient infrastructure, and the need for climate action. Given this context, here (i) a synthesis is presented of the role of geoscience in successfully achieving these major global development frameworks agreed in 2015, (ii) the ethical and social understanding that underpins effective engagement by geoscientists in the science-policy-practice interface is discussed, and (iii) this required ethical understanding is placed into the context of geoscience training and development needs. This approach demonstrates the importance of geoscientists from across all sectors and specialisms, engaging in the implementation, monitoring and evaluation of global development frameworks. It highlights the importance of a greater awareness and consideration of our ethical responsibilities in

    The pressure on the Earth's environment and resources is the ultimate result of population growth and the only humane means available for stabilizing world population is to increase per capita living standards in the developing countries. However, this will require a very large increase in global energy consumption. If, as at present, the energy demand is met largely by fossil fuels, atmospheric concentrations of CO 2 will rise rapidly. Until the end of the century, and perhaps beyond it, any actions to control CO 2 emissions will be taken for precautionary reasons alone, because no reliable basis will exist for predicting their global (or regional) impact on the climate. The sustainability of the natural environment is also under threat from human activities such as the clearing of forests for crop-growing and grazing. The resulting elimination of habitats for, and genetic variability in, the victor is as serious a concern as global warming. The economic and social consequences of rigidly curtailing the growth of energy use in developed countries would be severe, and in developing countries extreme; even then greenhouse gas build up could only be slowed not prevented. On the other hand, a wealthier world would be more able to bear the financial burden of protecting biodiversity. It is concluded that since the developed countries on whom the main cost would have to fall, adequate effort into both biodiversity and greenhouse gas reduction, biodiversity must take procedence.

  17. Diffuse radiation increases global ecosystem-level water-use efficiency

    Current environmental changes lead not only to rising atmospheric CO2 levels and air temperature but also to changes in air pollution and thus the light quality of the solar radiation reaching the land-surface. While rising CO2 levels are thought to enhance photosynthesis and closure of stomata, thus leading to relative water savings, the effect of diffuse radiation on transpiration by plants is less clear. It has been speculated that the stimulation of photosynthesis by increased levels of diffuse light may be counteracted by higher transpiration and consequently water depletion and drought stress. Ultimately, in water co-limited systems, the overall effect of diffuse radiation will depend on the sensitivity of canopy transpiration versus photosynthesis to diffuse light, i.e. whether water-use efficiency changes with relative levels of diffuse light. Our study shows that water-use efficiency increases significantly with higher fractions of diffuse light. It uses the ecosystem-atmosphere gas-exchange observations obtained with the eddy covariance method at 29 flux tower sites. In contrast to previous global studies, the analysis is based directly on measurements of diffuse radiation. Its effect on water-use efficiency was derived by analyzing the multivariate response of carbon and water fluxes to radiation and air humidity using a purely empirical approach based on artificial neural networks. We infer that per unit change of diffuse fraction the water-use efficiency increases up to 40% depending on diffuse fraction levels and ecosystem type. Hence, in regions with increasing diffuse radiation positive effects on primary production are expected even under conditions where water is co-limiting productivity.

    Since the end of World War II, global agriculture has undergone a period of rapid intensification achieved through a combination of increased applications of chemical fertilizers, pesticides, and herbicides, the implementation of best management practice techniques, mechanization, irrigation, and more recently, through the use of optimized seed varieties and genetic engineering. However, not all crops and not all regions of the world have realized the same improvements in agricultural intensity. In this study we examine both the magnitude and spatial variation of new agricultural production potential from closing of 'yield gaps' for 20 ethanol and biodiesel feedstock crops. With biofuels coming under increasing pressure to slow or eliminate indirect land-use conversion, the use of targeted intensification via established agricultural practices might offer an alternative for continued growth. We find that by closing the 50th percentile production gap-essentially improving global yields to median levels-the 20 crops in this study could provide approximately 112.5 billion liters of new ethanol and 8.5 billion liters of new biodiesel production. This study is intended to be an important new resource for scientists and policymakers alike-helping to more accurately understand spatial variation of yield and agricultural intensification potential, as well as employing these data to better utilize existing infrastructure and optimize the distribution of development and aid capital.

  2. How to Quantify Human-environment Interactions in the Past: A Global Historical Land Use Data Set for the Holocene

    2015-12-01

    Land use plays an important role in the climate system. Many ecosystem processes are directly or indirectly climate driven, and together with human driven land use changes, they determine how the land surface will evolve through time. To assess the effects of land cover changes on the climate system, models are required which are capable of simulating interactions between the involved components of the Earth system. Since driving forces for global environmental change differ among regions, a geographically (spatially) explicit modeling approach is called for, so that it can be incorporated in global and regional (climate and/or biophysical) change models in order to enhance our understanding of the underlying processes and thus improving future projections.Some researchers suggest that mankind has shifted from living in the Holocene (~emergence of agriculture) into the Anthropocene (~humans capable of changing the Earth' atmosphere) since the start of the Industrial Revolution. But in the light of the sheer size and magnitude of some historical land use changes (e.g. the Black Plague in the 14th century and the aftermath of the Colombian Exchange in the 16th century), some believe that this point might have occurred earlier in time. There are still many uncertainties and gaps in our knowledge about the importance of land use (change) in the global biogeochemical cycle, and it is crucial that researchers from other disciplines are involved in decreasing the uncertainties.Thus, integrated records of the co-evolving human-environment system over millennia are needed to provide a basis for a deeper understanding of the present and for forecasting the future. This requires the major task of assembling and integrating regional and global historical, archaeological, and paleo-environmental records. Humans cannot predict the future. Here I present a tool for such long term global change studies; it is the latest update (v 3.2) of the History Database of the Global

    At the beginning of the new century Humankind is facing a new Era. It has to face the effects of a dramatic and accelerated population growth. Human population size increased from one billion in 1835, to six billion by the end of this century. This unprecedented increase in number, affecting specific geographical areas, has augmented the deterioration of the natural environment caused by the misuse of natural resources and the depletion of fertile soils due to climatic changes and pollution. The quality of life is now diminished by the "greenhouse effect" which is the direct result of industrialisation. Ecological integrity is a concept that has to be advanced in order to facilitate the protection of biological and ecological resources against the threat of human survival. Global Bioethics as a discipline of interaction of health professionals with the present endangered environment, the limited global resources and the new biotechnologies is needed in any Biomedical School.

    Science.gov (United States)

    1993-02-01

    Inequalities in distribution of wealth, uneven use and distribution of resources, and human settlement patterns contribute more to environmental degradation than does population size. Current global economic strategies and policy decisions affect population and the natural environment. Large-scale technology and communications, the globalization of capital, subordination within world markets, and increasing consumption levels have broken down livelihoods and the environment. Therefore, contrary to popular opinion, population growth is not the key variable in environmental degradation. The erosion of livelihoods really affect women, especially poor women. Legal and political rights, women's economic independence, education, health, access to reproductive health services, and improved child survival greatly influence fertility decline. The disintegration of women's livelihoods restricts their access to health services and education. We cannot depend on capitalism to protect our livelihoods or the health of the environment. So nongovernmental organizations, international agencies, and national and local governments must do so. Assessments of intensive agriculture, industries destroying the social and physical environment, and military activities are critically needed. We need to reassess the macroeconomic forces affecting the natural environment and livelihoods of the poor. Communities should influence and demand policies and regulations preserving their access to resources. Women must participate more intensely in decision making. They should have access to key services. Citizens should have more access to information on environmental damage of industrialized products and processes. All of us need to advocate for more environmentally sound and sustainable forms of development and technology. People at the local, national, and global levels must work to change values that have caused overconsumption, thereby promoting a new ethic centering on caring for people and the

    Full Text Available Climate changes and expected variability of climatic parameters represent a serious concern of the 21st century agriculture. At the global level, the further rise in temperature, changed quantity and distribution of precipitation, increased variability of climate parameters and the occurrence of extreme climate events are expected. In order to avoid, or at least reduce the negative effects of global climate change, several adaptation strategies are proposed. Adjustment of production technology and breeding for tolerance to changed environment are proposed as two most important adaptation measures.

    Changes in tree growth rates can affect tree mortality and forest feedbacks to the global carbon cycle. As air temperature increases, evaporative demand also increases, increasing effective drought in forest ecosystems. Using a spatially comprehensive network of Douglas fir (Pseudotsuga menziesii) chronologies from 122 locations that represent distinct climate environments in the western United States, we show that increased temperature decreases growth via vapor pressure deficit (VPD) across all latitudes. Using an ensemble of global circulation models, we project an increase in both the mean VPD associated with the lowest growth extremes and the probability of exceeding these VPD values. As temperature continues to increase in future decades, we can expect deficit-related stress to increase and consequently Douglas fir growth to decrease throughout its US range.

Conventionally, water-related engineering projects have managed amphibious spaces through terrestrial approaches premised on removing or controlling water, for example by land reclamation and drainage. They can be contrasted with amphibious approaches that take water flows as a given and organize life around it––as exemplified by living in floating villages or houses on stilts, using water as a primary mode of transportation, or growing crops in water. Yet, the amphibious is gaining new life, as water seems to be increasingly flowing back into land, everywhere giving rise to emergencies that call for creative response. Thus, urban planners, engineers, and architects devise new infrastructures and models adaptive to environments that are becoming amphibious once again, or for the first time, and people living in watery environments everywhere find ways of adapting to increasingly amphibious circumstances. Doing so, they are contributing to the ongoing ontological transformation of amphibious worlds. This introduction to the thematic collection on “Amphibious Worlds: Environments, Infrastructures, Ontologies,” outlines some of the key issues facing STS and anthropological studies of such worlds, and introduces the papers that follow.

  13. What are the major global threats and impacts in marine environments? Investigating the contours of a shared perception among marine scientists from the bottom-up

  15. Role of stranded gas in increasing global gas supplies

    Attanasi, E.D.; Freeman, P.A.

    2013-01-01

    This report synthesizes the findings of three regional studies in order to evaluate, at the global scale, the contribution that stranded gas resources can make to global natural gas supplies. Stranded gas, as defined for this study, is natural gas in discovered conventional gas and oil fields that is currently not commercially producible for either physical or economic reasons. The regional studies evaluated the cost of bringing the large volumes of undeveloped gas in stranded gas fields to selected markets. In particular, stranded gas fields of selected Atlantic Basin countries, north Africa, Russia, and central Asia are screened to determine whether the volumes are sufficient to meet Europe’s increasing demand for gas imports. Stranded gas fields in Russia, central Asia, Southeast Asia, and Australia are also screened to estimate development, production, and transport costs and corresponding gas volumes that could be supplied to Asian markets in China, India, Japan, and South Korea. The data and cost analysis presented here suggest that for the European market and the markets examined in Asia, the development of stranded gas provides a way to meet projected gas import demands for the 2020-to-2040 period. Although this is a reconnaissance-type appraisal, it is based on volumes of gas that are associated with individual identified fields. Individual field data were carefully examined. Some fields were not evaluated because current technology was insufficient or it appeared the gas was likely to be held off the export market. Most of the evaluated stranded gas can be produced and delivered to markets at costs comparable to historical prices. Moreover, the associated volumes of gas are sufficient to provide an interim supply while additional technologies are developed to unlock gas diffused in shale and hydrates or while countries transition to making a greater use of renewable energy sources.

The fundamentals of natural climate change, the atmospheric environment, factors that influence climate, and the greenhouse effect are explained. Global warming is then discussed with reference to paleoclimatic research, the influence of human activity on increased concentrations of greenhouse gases, and predictions of future climates. The possible impacts of global warming on Canada are described for such sectors as forests, fisheries, agriculture, sea levels, health, energy supply and demand, and the Arctic regions. The actions that citizens and governments can take in order to mitigate or adapt to global warming are then presented. A glossary and index are included. 55 refs., 17 figs

  17. Bringing the Global Scale to Education in Natural Resources Management

    Given the ominous trajectory of rapid global environmental change, environmental managers must grapple with global scale structures, processes, and concepts. The concept of the Anthropocene Epoch, albeit contested, is highly integrative across disciplines and temporal scales, and thus potentially helpful in the context of educating environmental managers. It can be framed temporally in terms of the geologic history of the global environment, the initiation and acceleration of anthropogenic impacts on the environment, and a future global environment that is highly dependent on human decisions. A key lesson from Earth's pre-human geologic history is that global climate has generally been linked to greenhouse gas concentrations, and many mass extinction events were associated with high greenhouse gas concentrations. The pervasive impacts of the contemporary technosphere on the biosphere point especially to the need to conserve biosphere capital. Scenarios of Earth's future environment, based on Earth system models, suggest that business-as-usual technologies and economic practices will set the stage for a biophysical environment that is hostile (if not inimical) to a high technology global civilization. These lessons can inform and inspire sub-global management efforts to mitigate and adapt to global environmental change.

  18. Global climate convention

    The effort of negotiate a global convention on climate change is one of mankind's great endeavours - and a challenge to economists and development planners. The inherent linkages between climate and the habitability of the earth are increasingly well recognized, and a convention could help to ensure that conserving the environment and developing the economy in the future must go hand in hand. Due to growing environmental concern the United Nations General Assembly has set into motion an international negotiating process for a framework convention on climate change. One the major tasks in these negotiations is how to share the duties in reducing climate relevant gases, particularly carbon dioxide (CO 2 ), between the industrial and the developing countries. The results and proposals could be among the most far-reaching ever for socio-economic development, indeed for global security and survival itself. While the negotiations will be about climate and protection of the atmosphere, they will be on fundamental global changes in energy policies, forestry, transport, technology, and on development pathways with low greenhouse gas emissions. Some of these aspects of a climate convention, particularly the distributional options and consequences for the North-South relations, are addressed in this chapter. (orig.)

    Full Text Available Because bisphenol A (BPA is a high production volume chemical, we examined over 500 peer-reviewed studies to understand its global distribution in effluent discharges, surface waters, sewage sludge, biosolids, sediments, soils, air, wildlife, and humans. Bisphenol A was largely reported from urban ecosystems in Asia, Europe, and North America; unfortunately, information was lacking from large geographic areas, megacities, and developing countries. When sufficient data were available, probabilistic hazard assessments were performed to understand global environmental quality concerns. Exceedances of Canadian Predicted No Effect Concentrations for aquatic life were >50% for effluents in Asia, Europe, and North America but as high as 80% for surface water reports from Asia. Similarly, maximum concentrations of BPA in sediments from Asia were higher than Europe. Concentrations of BPA in wildlife, mostly for fish, ranged from 0.2 to 13 000 ng/g. We observed 60% and 40% exceedences of median levels by the US Centers for Disease Control and Prevention’s National Health and Nutrition Examination Survey in Europe and Asia, respectively. These findings highlight the utility of coordinating global sensing of environmental contaminants efforts through integration of environmental monitoring and specimen banking to identify regions for implementation of more robust environmental assessment and management programs.

    2013-12-01

    Chytridiomycosis, which is caused by Batrachochytrium dendrobatidis, is an emerging infectious disease of amphibians. The disease is one of the main causes of the global decline in amphibians. The aetiological agent is ubiquitous, with worldwide distribution, and affects a large number of amphibian species in several biomes. In the last decade, scientific research has substantially increased knowledge of the aetiological agent and the associated infection. However, important epidemiological aspects of the environment-mediated interactions between the aetiological agent and the host are not yet clear. The objective of the present review is to describe chytridiomycosis with regard to the major features of the aetiological agent, the host and the environment.

  1. International Trade Drives Global Resource Use: A Structural Decomposition Analysis of Raw Material Consumption from 1990-2010.

    2018-04-03

    Globalization led to an immense increase of international trade and the emergence of complex global value chains. At the same time, global resource use and pressures on the environment are increasing steadily. With these two processes in parallel, the question arises whether trade contributes positively to resource efficiency, or to the contrary is further driving resource use? In this article, the socioeconomic driving forces of increasing global raw material consumption (RMC) are investigated to assess the role of changing trade relations, extended supply chains and increasing consumption. We apply a structural decomposition analysis of changes in RMC from 1990 to 2010, utilizing the Eora multi-regional input-output (MRIO) model. We find that changes in international trade patterns significantly contributed to an increase of global RMC. Wealthy developed countries play a major role in driving global RMC growth through changes in their trade structures, as they shifted production processes increasingly to less material-efficient input suppliers. Even the dramatic increase in material consumption in the emerging economies has not diminished the role of industrialized countries as drivers of global RMC growth.

    criticism. Islam has found two major support-bases for its translation in Southeast Asia: the state and the autonomous religious leaders. With the increasing sophistication and penetration of Western colonialism, modern Muslim organizations gradually have taken over the social role of the defunct indigenous states and other institutions. Southeast Asian Muslims have shown their moral vision of the globalized world and their design to achieve it. In this article, emphasis is given to major trends in spirituality centered movement among Southeast Asian Muslims as represented by mass organizations, the reformed traditional institutions, and the more pronounced social movements in the region. Despite the fact that the state's hegemony and the ever presence of the shari'a at times interfere with and color the activities of these movements, they have undeniably demonstrated the viability and potential of spirituality centered movement in reshaping the rapidly changing and more globalized world of today.

    The tropical forest regeneration technology research group of Kansai Electric Power Company and Kansai Environment Center has been performing the research and development of tropical forest regeneration technology jointly with Indonesia since fiscal 1992. The group was awarded with the Global Environment Technology Prize from Nihon Keizai Shimbun, Inc. As a result of stringent examination on 97 applications, being two times as many as in usual years, the group received high evaluation on the originality, reality and possibility of proliferation of its research, and impacts given to the societies. Two other groups were also selected. The achievements were reported by the representative of the group in the award commemoration lecture at the global environment economist summit held by the Nikkei press the same day. Conventionally, afforestation done with considerable efforts has often been lost by forest fires and slash-and-burn farming, whereas the present research aims at establishing a comprehensive afforestation technology considering social and economic aspects, and CO2 fixation. As one of the choices of flexible measures as a result of the effect of forests having been recognized in COP3, frameworks for utilizing the mechanisms of joint implementation and clean resource development were introduced. Ever increasing expectations are placed on the achievements of the present research works. (NEDO)

    GLOBE is a global educational program for elementary and high school levels, and its main purpose in Costa Rica is to develop scientific thinking and interest for science in high school students through hydrology research projects that allow them to relate science with environmental issues in their communities. Youth between 12 and 17 years old from public schools participate in science clubs outside of their regular school schedule. A comparison study was performed between different groups, in order to assess GLOBE's applicability as a learning science atmosphere and the motivation and interest it generates in students toward science. Internationally applied scales were used as tools for measuring such indicators, adapted to the Costa Rican context. The results provide evidence statistically significant that the students perceive the GLOBE atmosphere as an enriched environment for science learning in comparison with the traditional science class. Moreover, students feel more confident, motivated and interested in science than their peers who do not participate in the project. However, the results were not statistically significant in this last respect.

  7. Wind increases leaf water use efficiency.

    Schymanski, Stanislaus J; Or, Dani

    2016-07-01

    A widespread perception is that, with increasing wind speed, transpiration from plant leaves increases. However, evidence suggests that increasing wind speed enhances carbon dioxide (CO2 ) uptake while reducing transpiration because of more efficient convective cooling (under high solar radiation loads). We provide theoretical and experimental evidence that leaf water use efficiency (WUE, carbon uptake per water transpired) commonly increases with increasing wind speed, thus improving plants' ability to conserve water during photosynthesis. Our leaf-scale analysis suggests that the observed global decrease in near-surface wind speeds could have reduced WUE at a magnitude similar to the increase in WUE attributed to global rise in atmospheric CO2 concentrations. However, there is indication that the effect of long-term trends in wind speed on leaf gas exchange may be compensated for by the concurrent reduction in mean leaf sizes. These unintuitive feedbacks between wind, leaf size and water use efficiency call for re-evaluation of the role of wind in plant water relations and potential re-interpretation of temporal and geographic trends in leaf sizes. © 2015 The Authors.

    The IMAGE 2.0 model is a multi-disciplinary, integrated model, designed to simulate the dynamics of the global society-biosphere-climate system. In this paper the focus is on the scientific aspects of the model, while another paper in this volume emphasizes its political aspects. The objectives of IMAGE 2.0 are to investigate linkages and feedbacks in the global system, and to evaluate consequences of climate policies. Dynamic calculations are performed to the year 2100, with a spatial scale ranging from grid (0.5x0.5 latitude-longitude) to world political regions, depending on the sub-model. A total of 13 sub-models make up IMAGE 2.0, and they are organized into three fully linked sub-systems: Energy-Industry, Terrestrial Environment, and Atmosphere-Ocean. The fully linked model has been tested against data from 1970 to 1990, and after calibration it can reproduce the following observed trends: regional energy consumption and energy-related emissions, terrestrial flux of carbon dioxide and emissions of greenhouse gases, concentrations of greenhouse gases in the atmosphere, and transformation of land cover. The model can also simulate current zonal average surface and vertical temperatures. 1 fig., 10 refs

  9. River export of triclosan from land to sea: A global modelling approach.

    Science.gov (United States)

    van Wijnen, Jikke; Ragas, Ad M J; Kroeze, Carolien

    2018-04-15

    Triclosan (TCS) is an antibacterial agent that is added to commonly used personal care products. Emitted to the aquatic environment in large quantities, it poses a potential threat to aquatic organisms. Triclosan enters the aquatic environment mainly through sewage effluent. We developed a global, spatially explicit model, the Global TCS model, to simulate triclosan transport by rivers to coastal areas. With this model we analysed annual, basin-wide triclosan export for the year 2000 and two future scenarios for the year 2050. Our analyses for 2000 indicate that triclosan export to coastal areas in Western Europe, Southeast Asia and the East Coast of the USA is higher than in the rest of the world. For future scenarios, the Global TCS model predicts an increase in river export of triclosan in Southeast Asia and a small decrease in Europe. The number of rivers with an annual average triclosan concentration at the river mouth that exceeds a PNEC of 26.2ng/L is projected to double between 2000 and 2050. This increase is most prominent in Southeast Asia, as a result of fast population growth, increasing urbanisation and increasing numbers of people connected to sewerage systems with poor wastewater treatment. Predicted triclosan loads correspond reasonably well with measured values. However, basin-specific predictions have considerable uncertainty due to lacking knowledge and location-specific data on the processes determining the fate of triclosan in river water, e.g. sorption, degradation and sedimentation. Additional research on the fate of triclosan in river systems is therefore recommended. We developed a global spatially explicit model to simulate triclosan export by rivers to coastal seas. For two future scenarios this Global TCS model projects an increase in river export of triclosan to several seas around the world. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available The paper presents main trends in global economic development and impact thereof on Ukraine. A characteristic feature of the contemporary world is acceleration of globalization caused by achievements of the scientific and technological progress, which have provided technical means for successful overcoming the factors of time and space, whereby making the world more compact and ensuring the possibility of functioning as a single economic mechanism. Growing of opportunities for solving global problems is accompanied by aggravation of the latter such as: population growth, depletion of natural resources, deterioration of the environment, the mounting danger of climatic changes, potential failure to provide people with foods and potable water. Growth of social inequality in the world is also observed, as is increased differentiation of population by income level, which intensifies migration processes and thereby creates new problems related to coexistence of people belonging to different civilizations, cultures and value systems. An integral part of globalization is formation of regional associations which requires Ukraine to participate in this phase of globalization by means of becoming a member of a regional integration association with the purpose of improving its competitiveness and ensuring decent living for Ukrainian people under conditions of humanity functioning as a single planetary organism

    Slominski, Andrzej T; Zmijewski, Michal A; Skobowiat, Cezary; Zbytek, Blazej; Slominski, Radomir M; Steketee, Jeffery D

    2012-01-01

    Skin, the body's largest organ, is strategically located at the interface with the external environment where it detects, integrates, and responds to a diverse range of stressors including solar radiation. It has already been established that the skin is an important peripheral neuro-endocrine-immune organ that is tightly networked to central regulatory systems. These capabilities contribute to the maintenance of peripheral homeostasis. Specifically, epidermal and dermal cells produce and respond to classical stress neurotransmitters, neuropeptides, and hormones. Such production is stimulated by ultraviolet radiation (UVR), biological factors (infectious and noninfectious), and other physical and chemical agents. Examples of local biologically active products are cytokines, biogenic amines (catecholamines, histamine, serotonin, and N-acetyl-serotonin), melatonin, acetylocholine, neuropeptides including pituitary (proopiomelanocortin-derived ACTH, beta-endorphin or MSH peptides, thyroid-stimulating hormone) and hypothalamic (corticotropin-releasing factor and related urocortins, thyroid-releasing hormone) hormones as well as enkephalins and dynorphins, thyroid hormones, steroids (glucocorticoids, mineralocorticoids, sex hormones, 7-delta steroids), secosteroids, opioids, and endocannabinoids. The production of these molecules is hierarchical, organized along the algorithms of classical neuroendocrine axes such as hypothalamic-pituitary-adrenal axis (HPA), hypothalamic-thyroid axis (HPT), serotoninergic, melatoninergic, catecholaminergic, cholinergic, steroid/secosteroidogenic, opioid, and endocannbinoid systems. Dysregulation of these axes or of communication between them may lead to skin and/ or systemic diseases. These local neuroendocrine networks are also addressed at restricting maximally the effect of noxious environmental agents to preserve local and consequently global homeostasis. Moreover, the skin-derived factors/systems can also activate cutaneous nerve

    The Dynamic, Exascale Global Address Space programming environment (DEGAS) project will develop the next generation of programming models and runtime systems to meet the challenges of Exascale computing. Our approach is to provide an efficient and scalable programming model that can be adapted to application needs through the use of dynamic runtime features and domain-specific languages for computational kernels. We address the following technical challenges: Programmability: Rich set of programming constructs based on a Hierarchical Partitioned Global Address Space (HPGAS) model, demonstrated in UPC++. Scalability: Hierarchical locality control, lightweight communication (extended GASNet), and ef- ficient synchronization mechanisms (Phasers). Performance Portability: Just-in-time specialization (SEJITS) for generating hardware-specific code and scheduling libraries for domain-specific adaptive runtimes (Habanero). Energy Efficiency: Communication-optimal code generation to optimize energy efficiency by re- ducing data movement. Resilience: Containment Domains for flexible, domain-specific resilience, using state capture mechanisms and lightweight, asynchronous recovery mechanisms. Interoperability: Runtime and language interoperability with MPI and OpenMP to encourage broad adoption.

    Glioblastoma (GBM) is a deadly disease with few effective therapies. Although much has been learned about the molecular characteristics of the disease, this knowledge has not been translated into clinical improvements for patients. At the same time, many new therapies are being developed. Many of these therapies have potential biomarkers to identify responders. The result is an enormous amount of testable clinical questions that must be answered efficiently. The GBM Adaptive Global Innovative Learning Environment (GBM AGILE) is a novel, multi-arm, platform trial designed to address these challenges. It is the result of the collective work of over 130 oncologists, statisticians, pathologists, neurosurgeons, imagers, and translational and basic scientists from around the world. GBM AGILE is composed of two stages. The first stage is a Bayesian adaptively randomized screening stage to identify effective therapies based on impact on overall survival compared with a common control. This stage also finds the population in which the therapy shows the most promise based on clinical indication and biomarker status. Highly effective therapies transition in an inferentially seamless manner in the identified population to a second confirmatory stage. The second stage uses fixed randomization to confirm the findings from the first stage to support registration. Therapeutic arms with biomarkers may be added to the trial over time, while others complete testing. The design of GBM AGILE enables rapid clinical testing of new therapies and biomarkers to speed highly effective therapies to clinical practice.

    2012-03-01

    Full Text Available The current complexity of sustainable development in the Global South calls for the design of learning strategies that can deal with this complexity. One such innovative learning strategy, called Visual Problem Appraisal (VPA, is highlighted in this article. The strategy is termed visual as it creates a learning environment that is film-based. VPA enhances the analysis of complex issues, and facilitates stakeholder dialogue and action planning. The strategy is used in workshops dealing with problem analysis and policy design, and involves the participants “meeting” stakeholders through filmed narratives. The article demonstrates the value of using film in multi stakeholder learning environments addressing issues concerning sustainable development.

  19. Plastics in the Marine Environment.

    Law, Kara Lavender

    2017-01-03

    Plastics contamination in the marine environment was first reported nearly 50 years ago, less than two decades after the rise of commercial plastics production, when less than 50 million metric tons were produced per year. In 2014, global plastics production surpassed 300 million metric tons per year. Plastic debris has been detected worldwide in all major marine habitats, in sizes from microns to meters. In response, concerns about risks to marine wildlife upon exposure to the varied forms of plastic debris have increased, stimulating new research into the extent and consequences of plastics contamination in the marine environment. Here, I present a framework to evaluate the current understanding of the sources, distribution, fate, and impacts of marine plastics. Despite remaining knowledge gaps in mass budgeting and challenges in investigating ecological impacts, the increasing evidence of the ubiquity of plastics contamination in the marine environment, the continued rapid growth in plastics production, and the evidence-albeit limited-of demonstrated impacts to marine wildlife support immediate implementation of source-reducing measures to decrease the potential risks of plastics in the marine ecosystem.

    Plastics contamination in the marine environment was first reported nearly 50 years ago, less than two decades after the rise of commercial plastics production, when less than 50 million metric tons were produced per year. In 2014, global plastics production surpassed 300 million metric tons per year. Plastic debris has been detected worldwide in all major marine habitats, in sizes from microns to meters. In response, concerns about risks to marine wildlife upon exposure to the varied forms of plastic debris have increased, stimulating new research into the extent and consequences of plastics contamination in the marine environment. Here, I present a framework to evaluate the current understanding of the sources, distribution, fate, and impacts of marine plastics. Despite remaining knowledge gaps in mass budgeting and challenges in investigating ecological impacts, the increasing evidence of the ubiquity of plastics contamination in the marine environment, the continued rapid growth in plastics production, and the evidence—albeit limited—of demonstrated impacts to marine wildlife support immediate implementation of source-reducing measures to decrease the potential risks of plastics in the marine ecosystem.

    2011-01-01

    To examine the impact of globalization on employee psychological health and job satisfaction via job characteristics (i.e., job demands and job resources) in an emerging economy, that of Malaysia. As external factors are regarded as influences on the working environment, we hypothesized that global forces (increased pressure and competition) would have an impact on burnout and job satisfaction via increased demands (role conflict, emotional demands) and reduced resources (supervisor support, coworkers support). Data were collected using a population based survey among 308 employees in the state of Selangor, Malaysia. Participants were approached at home during the weekend or on days off from work. Only one participant was selected per household. Structural equation modelling was used to analyse the data. Nearly 54% of respondents agreed that they need to work harder, 25% agreed that their job was not secure and 24% thought they had lost power and control on the job due to global trade competition. Consistent with our predictions, demands mediated the globalization to burnout relationship, and resources mediated the globalization to job satisfaction relationship. Together, these results support the idea that external factors influence work conditions and in turn employee health and job satisfaction. We conclude that the jobs demands-resources framework is applicable in an Eastern setting and that globalization is a key antecedent of working environments.

    While researchers have long held that discrimination cannot endure in an increasingly competitive environment, there has been little work testing this dynamic process. This paper tests the hypothesis (based on Becker 1957) that increased competition resulting from globalization in the 1980s forced employers to reduce costly discrimination against women. The empirical strategy exploits differences in market structure across industries to identify the impact of trade on the gender wage gap: bec...

    In the context of a globalised world, reports on health that extend personal or country borders have increasing relevance. Media can promote opportunities to identify and address gaps in important global health issues. In light of the potential role of media as an advocacy tool for global health, we examined how global health issues are represented in mainstream media in New Zealand. We conducted a content analysis of media reports on global health issues in the four highest circulation newspapers in New Zealand between June 2007 and May 2009. Search terms included 'global health, 'international health' and 'world health'. Communicable disease was the most frequently reported global health issue in New Zealand newspapers, followed by environment (e.g. climate change), general health risks (unsafe pharmaceuticals) and substance use (tobacco and alcohol). Chronic disease, injury or their determinants were less frequently reported. Mainstream media favours health-related reports based on crisis, epidemic or acute conditions over chronic or non-communicable diseases or disability. Health issues facing the Asia Pacific region increasingly include chronic diseases, which would benefit from greater media coverage to increase advocacy and political awareness of global health challenges.

  6. The Influence of Low-carbon Economy on Global Trade Pattern

    Science.gov (United States)

    Xiao-jing, Guo

    Since global warming has seriously endangered the living environment of human being and their health and safety, the development of low-carbon economy has become an irreversible global trend. Under the background of economic globalization, low-carbon economy will surely exert a significant impact on global trade pattern. Countries are paying more and more attention to the green trade. The emission permits trade of carbon between the developed countries and the developing countries has become more mature than ever. The carbon tariff caused by the distribution of the "big cake" will make the low-cost advantage in developing countries cease to exist, which will, in turn, affect the foreign trade, economic development, employment and people's living in developing countries. Therefore, under the background of this trend, we should perfect the relevant laws and regulations on trade and environment as soon as possible, optimize trade structure, promote greatly the development of service trade, transform thoroughly the mode of development in foreign trade, take advantage of the international carbon trading market by increasing the added value of export products resulted from technological innovation to achieve mutual benefit and win-win results and promote common development.

    Alzheimer disease (AD) is a growing global health and economic issue as elderly populations increase dramatically across the world. Despite the many clinical trials conducted, currently no approved disease-modifying treatment exists. In this commentary, the present status of AD drug development and the grounds for collaborations between government, academia, and industry to accelerate the development of disease-modifying AD therapies are discussed. Official government documents, literature, and news releases were surveyed by MEDLINE and website research. Currently approved anti-AD drugs provide only short-lived symptomatic improvements, which have no effect on the underlying pathogenic mechanisms or progression of the disease. The failure to approve a disease-modifying drug for AD may be because the progression of AD in the patient populations enrolled in clinical studies was too advanced for drugs to demonstrate cognitive and functional improvements. The US Food and Drug Administration and the European Medicines Agency recently published draft guidance for industry which discusses approaches for conducting clinical studies with patients in early AD stages. For successful clinical trials in early-stage AD, however, it will be necessary to identify biomarkers highly correlated with the clinical onset and the longitudinal progress of AD. In addition, because of the high cost and length of clinical AD studies, support in the form of global initiatives and collaborations between government, industry, and academia is needed. In response to this situation, national guidance and international collaborations have been established. Global initiatives are focusing on 2025 as a goal to provide new treatment options, and early signs of success in biomarker and drug development are already emerging.

    Urban heat island (UHI) is a widely investigated phenomenon in the field of urban climate characterized by the warming of urban areas relative to its surrounding rural environs. Being able to understand the mechanism behind the UHI formation of a city and distinguish its impact from that of global climate change is indispensable when identifying adaptation and mitigation strategies. However, the lack of UHI studies many cities especially for developing countries makes it difficult to generalize the mechanism for UHI formation. Thus, there is an impending demand for studies that focus on the simultaneous analyses of UHI and its trends throughout the world. Hence, we propose a subfield of urban climatology, called "global urban climatology" (GUC), which mainly focuses on the uniform understanding of urban climates across all cities, globally. By using globally applicable methodologies to quantify and compare urban heat islands of cities with diverse backgrounds, including their geography, climate, socio-demography, and other factors, a universal understanding of the mechanisms underlying the formation of the phenomenon can be established. The implementation of GUC involves the use of globally acquired historical observation networks, gridded meteorological parameters from climate models, global geographic information system datasets; the construction of a distributed urban parameter database; and the development of techniques necessary to model the urban climate. Research under GUC can be categorized into three approaches. The collaborative approach (1st) relies on the collection of data from micro-scale experiments conducted worldwide with the aid or development of professional social networking platforms; the analytical approach (2nd) relies on the use of global weather station datasets and their corresponding objectively analysed global outputs; and the numerical approach (3rd) relies on the global estimation of high-resolution urban-representative parameters as

    Mass extinctions have profoundly impacted the evolution of life through not only reducing taxonomic diversity but also reshaping ecosystems and biogeographic patterns. In particular, they are considered to have driven increased biogeographic cosmopolitanism, but quantitative tests of this hypothesis are rare and have not explicitly incorporated information on evolutionary relationships. Here we quantify faunal cosmopolitanism using a phylogenetic network approach for 891 terrestrial vertebrate species spanning the late Permian through Early Jurassic. This key interval witnessed the Permian-Triassic and Triassic-Jurassic mass extinctions, the onset of fragmentation of the supercontinent Pangaea, and the origins of dinosaurs and many modern vertebrate groups. Our results recover significant increases in global faunal cosmopolitanism following both mass extinctions, driven mainly by new, widespread taxa, leading to homogenous 'disaster faunas'. Cosmopolitanism subsequently declines in post-recovery communities. These shared patterns in both biotic crises suggest that mass extinctions have predictable influences on animal distribution and may shed light on biodiversity loss in extant ecosystems.Mass extinctions are thought to produce 'disaster faunas', communities dominated by a small number of widespread species. Here, Button et al. develop a phylogenetic network approach to test this hypothesis and find that mass extinctions did increase faunal cosmopolitanism across Pangaea during the late Palaeozoic and early Mesozoic.

  11. Small global effect on terrestrial net primary production due to increased fossil fuel aerosol emissions from East Asia during the last decade.

    The global terrestrial carbon sink has increased since the start of this century at a time of rapidly growing carbon dioxide emissions from fossil fuel burning. Here we test the hypothesis that increases in atmospheric aerosols from fossil fuel burning have increased the diffuse fraction of incoming solar radiation and the efficiency of photosynthesis leading to increased plant carbon uptake. Using a combination of atmospheric and biospheric models, we find that changes in diffuse light associated with fossil fuel aerosol emission accounts for only 2.8% of the increase in global net primary production (1.221 PgC/yr) over the study period 1998 to 2007. This relatively small global signal is however a result of large regional compensations. Over East Asia, the strong increase in fossil fuel emissions contributed nearly 70% of the increased plant carbon uptake (21 TgC/yr), whereas the declining fossil fuel aerosol emissions in Europe and North America contributed negatively (-16% and -54%, respectively) to increased plant carbon uptake. At global scale, we also find the CO2 fertilization effect on photosynthesis to be the dominant driver of increased plant carbon uptake, in line with previous studies. These results suggest that further research into alternative mechanisms by which fossil fuel emissions could increase carbon uptake, such as nitrogen deposition and carbon-nitrogen interactions, is required to better understand a potential link between the recent changes in fossil fuel emissions and terrestrial carbon uptake.

  13. Wintertime urban heat island modified by global climate change over Japan

    Science.gov (United States)

    Hara, M.

    2015-12-01

    Urban thermal environment change, especially, surface air temperature (SAT) rise in metropolitan areas, is one of the major recent issues in urban areas. The urban thermal environmental change affects not only human health such as heat stroke, but also increasing infectious disease due to spreading out virus vectors habitat and increase of industry and house energy consumption. The SAT rise is mostly caused by global climate change and urban heat island (hereafter UHI) by urbanization. The population in Tokyo metropolitan area is over 30 millions and the Tokyo metropolitan area is one of the biggest megacities in the world. The temperature rise due to urbanization seems comparable to the global climate change in the major megacities. It is important to project how the urbanization and the global climate change affect to the future change of urban thermal environment to plan the adaptation and mitigation policy. To predict future SAT change in urban scale, we should estimate future UHI modified by the global climate change. This study investigates change in UHI intensity (UHII) of major metropolitan areas in Japan by effects of the global climate change. We performed a series of climate simulations. Present climate simulations with and without urban process are conducted for ten seasons using a high-resolution numerical climate model, the Weather Research and Forecasting (WRF) model. Future climate projections with and without urban process are also conducted. The future projections are performed using the pseudo global warming method, assuming 2050s' initial and boundary conditions estimated by a GCM under the RCP scenario. Simulation results indicated that UHII would be enhanced more than 30% in Tokyo during the night due to the global climate change. The enhancement of urban heat island is mostly caused by change of lower atmospheric stability.

    Full Text Available Nanoindustry evolution is caused by the global extension of new technological mode, which requires the construction of effective institutes and mechanisms of regulating its subjects’ relations. In the conditions of unfavorable external environment and unsolved internal problems of Russian nanoindustry development, not only the role of basic nanoindustrialization institutes increases, but the problem of reconstructing their activity and prospective updating of institutions arises. Regardless of level and scale, forms and content, the institutional reconstruction will become a part of a rapid response to external changes and a component of strategic programming of Russian nanoindustry. The Russian government acted as a main institute of national nanoindustry development and support. New special-purpose/universal, financial/nonfinancial, formal/informal institutes, which make up the structure of target investment and resource supply of nanoindustry at various stages of its formation, become active agents of state policy in this sphere. This institutional system should reflect the level and type structure of nanoindustry, corresponding to its strategic perspective. An important role in overcoming negative trends in nanoindustry now belongs not to formal and corporate development institutes but to associative, initiative and complementary ones partially replacing the state as its substitutes. The authors describe the options of international financial funds and integration-type institutes’ reconstruction for Russian nanoindustry in current situation. The feasibility of orienting the construction of nanoindustry institutes to basic relationships of its subjects that ensures their relevance and effectiveness, is argued. The authors’ version of nanoindustry institutes classification is suggested for applying as a testing analyzer of institutes functioning in order to determine their reconstruction directions, identify and supplement missing links

    DNA barcoding--the sequencing of short, standardized DNA regions for specimen identification and species discovery--has promised to facilitate rapid access to biodiversity knowledge by diverse users. Here, we advance our opinion that increased global participation in genetics research is beneficial, both to scientists and for science, and explore the premise that DNA barcoding can help to democratize participation in genetics research. We examine publication patterns (2003-2014) in the DNA barcoding literature and compare trends with those in the broader, related domain of genomics. While genomics is the older and much larger field, the number of nations contributing to the published literature is similar between disciplines. Meanwhile, DNA barcoding exhibits a higher pace of growth in the number of publications as well as greater evenness among nations in their proportional contribution to total authorships. This exploration revealed DNA barcoding to be a highly international discipline, with growing participation by researchers in especially biodiverse nations. We briefly consider several of the challenges that may hinder further participation in genetics research, including access to training and molecular facilities as well as policy relating to the movement of genetic resources.

    Unhealthy diets are heavily driven by unhealthy food environments. The International Network for Food and Obesity/non-communicable diseases (NCDs) Research, Monitoring and Action Support (INFORMAS) has been established to reduce obesity, NCDs and their related inequalities globally. This paper describes the design and methods of the first-ever, comprehensive national survey on the healthiness of food environments and the public and private sector policies influencing them, as a first step towards global monitoring of food environments and policies. A package of 11 substudies has been identified: (1) food composition, labelling and promotion on food packages; (2) food prices, shelf space and placement of foods in different outlets (mainly supermarkets); (3) food provision in schools/early childhood education (ECE) services and outdoor food promotion around schools/ECE services; (4) density of and proximity to food outlets in communities; food promotion to children via (5) television, (6) magazines, (7) sport club sponsorships, and (8) internet and social media; (9) analysis of the impact of trade and investment agreements on food environments; (10) government policies and actions; and (11) private sector actions and practices. For the substudies on food prices, provision, promotion and retail, 'environmental equity' indicators have been developed to check progress towards reducing diet-related health inequalities. Indicators for these modules will be assessed by tertiles of area deprivation index or school deciles. International 'best practice benchmarks' will be identified, against which to compare progress of countries on improving the healthiness of their food environments and policies. This research is highly original due to the very 'upstream' approach being taken and its direct policy relevance. The detailed protocols will be offered to and adapted for countries of varying size and income in order to establish INFORMAS globally as a new monitoring initiative

    It should be recognized that the key to the future is in the rational use of energy, that is, a more efficient use of energy rather than a continuous increase in the supply of energy. Every unit of energy saved is a unit of energy which does not have to be produced, and whose environmental impacts do not have to be dealt with. Massive reductions in the growth rates, and, where possible, in the absolute use of energy will help us to gain time to better understand and develop response strategies to problems like climate change on the acidification of the environment. In this sense the rational use of energy, including intensified energy efficiency measures is the most environmentally sound energy option with which we should move into the next century. 25 refs., 4 figs

    Differences in self-orientation (or "self-construal") may affect how the visual environment is attended, but the neural and cultural mechanisms that drive this remain unclear. Behavioral studies have demonstrated that people from Western backgrounds with predominant individualistic values are perceptually biased towards local-level information; whereas people from non-Western backgrounds that support collectivist values are preferentially focused on contextual and global-level information. In this study, we compared two groups differing in predominant individualistic (N = 15) vs collectivistic (N = 15) self-orientation. Participants completed a global/local perceptual conflict task whilst undergoing functional Magnetic Resonance Imaging (fMRI) scanning. When participants high in individualistic values attended to the global level (ignoring the local level), greater activity was observed in the frontoparietal and cingulo-opercular networks that underpin attentional control, compared to the match (congruent) baseline. Participants high in collectivistic values activated similar attentional control networks o only when directly compared with global processing. This suggests that global interference was stronger than local interference in the conflict task in the collectivistic group. Both groups showed increased activity in dorsolateral prefrontal regions involved in resolving perceptual conflict during heightened distractor interference. The findings suggest that self-orientation may play an important role in driving attention networks to facilitate interaction with the visual environment.

    The much anticipated year of 2012 is now here. Amidst the predictions and cosmic alignments that many are aware of, one thing is for sure: it will be an interesting and exciting year as the speed of change continues to increase, bringing both chaos and great opportunity. One benchmark of these times is a shift in many people from a paradigm of competition to one of greater cooperation. All across the planet, increasing numbers of people are practicing heart-based living, and more groups are forming activities that support positive change and creative solutions for manifesting a better world. The Global Coherence Initiative (GCI) is a science-based, co-creative project to unite people in heart-focused care and intention. GCI is working in concert with other initiatives to realize the increased power of collective intention and consciousness. The convergence of several independent lines of evidence provides strong support for the existence of a global information field that connects all living systems and consciousness. Every cell in our bodies is bathed in an external and internal environment of fluctuating invisible magnetic forces that can affect virtually every cell and circuit in biological systems. Therefore, it should not be surprising that numerous physiological rhythms in humans and global collective behaviors are not only synchronized with solar and geomagnetic activity, but disruptions in these fields can create adverse effects on human health and behavior. The most likely mechanism for explaining how solar and geomagnetic influences affect human health and behavior are a coupling between the human nervous system and resonating geomagnetic frequencies, called Schumann resonances, which occur in the earth-ionosphere resonant cavity and Alfvén waves. It is well established that these resonant frequencies directly overlap with those of the human brain and cardiovascular system.

    2014-11-14

    Lightning plays an important role in atmospheric chemistry and in the initiation of wildfires, but the impact of global warming on lightning rates is poorly constrained. Here we propose that the lightning flash rate is proportional to the convective available potential energy (CAPE) times the precipitation rate. Using observations, the product of CAPE and precipitation explains 77% of the variance in the time series of total cloud-to-ground lightning flashes over the contiguous United States (CONUS). Storms convert CAPE times precipitated water mass to discharged lightning energy with an efficiency of 1%. When this proxy is applied to 11 climate models, CONUS lightning strikes are predicted to increase 12 ± 5% per degree Celsius of global warming and about 50% over this century.

    Since the ecological footprint analysis in 1970s suggested changing consumption patterns and overpopulation concerns, energy policy such as energy conservation and use of renewable energy has become of prime importance. Several results of the long-term energy demand and supply analysis in 2050 or 2100 to reduce drastically carbon dioxide emission as a measure against global warming, showed the necessity of nuclear power deployment as well as maximum efforts to save energy, exploitation of the separation and disposal of carbon dioxide, and shifting energy sources to fuels that emit less greenhouse gases or non-fossil fuels. As a promising means to contribute to long-term energy supply, nuclear power generation is expected with improving safety, economic efficiency, environmental adaptability, and nuclear proliferation resistance of the technologies.

    We investigate changes in daily precipitation extremes using Tropical Rainfall Measuring Mission (TRMM) data (1998-2013), which coincides with the "global warming hiatus." Results show a change in probability distribution functions of local precipitation events (LPEs) during this period consistent with previous global warming studies, indicating increasing contrast between wet and dry extremes, with more intense LPE, less moderate LPE, and more dry (no rain) days globally. Analyses for land and ocean separately reveal more complex and nuanced changes over land, characterized by a strong positive trend (+12.0% per decade, 99% confidence level (c.l.)) in frequency of extreme LPEs over the Northern Hemisphere extratropics during the wet season but a negative global trend (-6.6% per decade, 95% c.l.) during the dry season. A significant global drying trend (3.2% per decade, 99% c.l.) over land is also found during the dry season. Regions of pronounced increased dry events include western and central U.S., northeastern Asia, and Southern Europe/Mediterranean.

    Speculation over a global rise in jellyfish populations has become widespread in the scientific literature, but until recently the purported ‘global increase’ had not been tested. Here we present a citation analysis of peer-reviewed literature to track the evolution of the current perception of increases in jellyfish and identify key papers involved in its establishment. Trend statements and citation threads were reviewed and arranged in a citation network. Trend statements were assessed according their degree of affirmation and spatial scale, and the appropriateness of the citations used to support statements was assessed. Analyses showed that 48.9% of publications misinterpreted the conclusions of cited sources, with a bias towards claiming jellyfish populations are increasing, with a single review having the most influence on the network. Collectively, these disparities resulted in a network based on unsubstantiated statements and citation threads. As a community, we must ensure our statements about scientific findings in general are accurately substantiated and carefully communicated such that incorrect perceptions, as in the case of jellyfish blooms, do not develop in the absence of rigorous testing. © 2016 John Wiley & Sons Ltd

    Full Text Available Global warming is expected to reduce oxygen solubility and vertical exchange in the ocean, changes which would be expected to result in an increase in the volume of hypoxic waters. A simulation made with a full Earth System model with dynamical atmosphere, ocean, sea ice and biogeochemical cycling (the Geophysical Fluid Dynamics Laboratory's Earth System Model 2.1 shows that this holds true if the condition for hypoxia is set relatively high. However, the volume of the most hypoxic (i.e., suboxic waters does not increase under global warming, as these waters actually become more oxygenated. We show that the rise in dissolved oxygen in the tropical Pacific is associated with a drop in ventilation time. A term-by-term analysis within the least oxygenated waters shows an increased supply of dissolved oxygen due to lateral diffusion compensating an increase in remineralization within these highly hypoxic waters. This lateral diffusive flux is the result of an increase of ventilation along the Chilean coast, as a drying of the region under global warming opens up a region of wintertime convection in our model. The results highlight the potential sensitivity of suboxic waters to changes in subtropical ventilation as well as the importance of constraining lateral eddy transport of dissolved oxygen in such waters.

    2012-06-05

    The current understanding of the global mercury (Hg) cycle remains uncertain because Hg behavior in the environment is very complicated. The special property of Hg causes the atmosphere to be the most important medium for worldwide dispersion and transformation. The source and fate of atmospheric Hg and its interaction with the surface environment are the essential topics in the global Hg cycle. Recent declining measurement trends of Hg in the atmosphere are in apparent conflict with the increasing trends in global anthropogenic Hg emissions. As the single largest country contributor of anthropogenic Hg emission, China's role in the global Hg cycle will become more and more important in the context of the decreasing man-made Hg emission from developed regions. However, much less Hg information in China is available. As a global pollutant which undergoes long-range transport and is persistence in the environment, increasing Hg knowledge in China could not only promote the Hg regulation in this country but also improve the understanding of the fundamental of the global Hg cycle and further push the abatement of this toxin on a global scale. Then the atmospheric Hg research in China may be a breakthrough for improving the current understanding of the global Hg cycle. However, due to the complex behavior of Hg in the atmosphere, a deeper understanding of the atmospheric Hg cycle in China needs greater cooperation across fields.

    Context: Accelerated globalization has produced obvious changes in diplomatic purposes and practices. Health issues have become increasingly preeminent in the evolving global diplomacy agenda. More leaders in academia and policy are thinking about how to structure and utilize diplomacy in pursuit of global health goals. Methods: In this article, we describe the context, practice, and components of global health diplomacy, as applied operationally. We examine the foundations of various approaches to global health diplomacy, along with their implications for the policies shaping the international public health and foreign policy environments. Based on these observations, we propose a taxonomy for the subdiscipline. Findings: Expanding demands on global health diplomacy require a delicate combination of technical expertise, legal knowledge, and diplomatic skills that have not been systematically cultivated among either foreign service or global health professionals. Nonetheless, high expectations that global health initiatives will achieve development and diplomatic goals beyond the immediate technical objectives may be thwarted by this gap. Conclusions: The deepening links between health and foreign policy require both the diplomatic and global health communities to reexamine the skills, comprehension, and resources necessary to achieve their mutual objectives.

    2012-01-01

    The U.S. Global Change Research Program (http://globalchange.gov) coordinates and integrates federal research on changes in the global environment and their implications for society. The USGCRP is developing a Global Change Information System (GCIS) that will centralize access to data and information related to global change across the U.S. federal government. The first implementation will focus on the 2013 National Climate Assessment (NCA) . (http://assessment.globalchange.gov) The NCA integrates, evaluates, and interprets the findings of the USGCRP; analyzes the effects of global change on the natural environment, agriculture, energy production and use, land and water resources, transportation, human health and welfare, human social systems, and biological diversity; and analyzes current trends in global change, both human-induced and natural, and projects major trends for the subsequent 25 to 100 years. The NCA has received over 500 distinct technical inputs to the process, many of which are reports distilling and synthesizing even more information, coming from thousands of individuals around the federal, state and local governments, academic institutions and non-governmental organizations. The GCIS will present a web-based version of the NCA including annotations linking the findings and content of the NCA with the scientific research, datasets, models, observations, etc. that led to its conclusions. It will use semantic tagging and a linked data approach, assigning globally unique, persistent, resolvable identifiers to all of the related entities and capturing and presenting the relationships between them, both internally and referencing out to other linked data sources and back to agency data centers. The developing W3C PROV Data Model and ontology will be used to capture the provenance trail and present it in both human readable web pages and machine readable formats such as RDF and SPARQL. This will improve visibility into the assessment process, increase

    2015-06-01

    Vibrio-related infections are increasing worldwide both in humans and aquatic animals. Rise in global sea surface temperature (SST), which is approximately 1 °C higher now than 140 years ago and is one of the primary physical impacts of global warming, has been linked to such increases. In this chapter, major known effects of increasing SST on the biology and ecology of vibrios are described. They include the effects on bacterial growth rate, both in the field and in laboratory, culturability, expression of pathogenicity traits, and interactions with aquatic organisms and abiotic surfaces. Special emphasis is given to the effect of ocean warming on Vibrio interactions with zooplankters, which represent one of the most important aquatic reservoirs for these bacteria. The reported findings highlight the biocomplexity of the interactions between vibrios and their natural environment in a climate change scenario, posing the need for interdisciplinary studies to properly understand the connection between ocean warming and persistence and spread of vibrios in sea waters and the epidemiology of the diseases they cause.

    The incidence of luminous reflections (LR) in captured images can interfere with the color of the affected regions. These regions tend to oversaturate, becoming whitish and, consequently, losing the original color information of the scene. Decision processes that employ images acquired from digital cameras can be impaired by the LR incidence. Such applications include real-time video surgeries, facial, and ocular recognition. This work proposes an algorithm called contrast enhancement of potential LR regions, which is a preprocessing to increase the contrast of potential LR regions, in order to improve the performance of automatic LR detectors. In addition, three automatic detectors were compared with and without the employment of our preprocessing method. The first one is a technique already consolidated in the literature called the Chang-Tseng threshold. We propose two automatic detectors called adapted histogram peak and global threshold. We employed four performance metrics to evaluate the detectors, namely, accuracy, precision, exactitude, and root mean square error. The exactitude metric is developed by this work. Thus, a manually defined reference model was created. The global threshold detector combined with our preprocessing method presented the best results, with an average exactitude rate of 82.47%.

  6. Reducing greenhouse gas emissions and improving air quality: Two global challenges.

    There are many good reasons to promote sustainable development and reduce greenhouse gas emissions and other combustion emissions. The air quality in many urban environments is causing many premature deaths because of asthma, cardiovascular disease, chronic obstructive pulmonary disease, lung cancer, and dementia associated with combustion emissions. The global social cost of air pollution is at least $3 trillion/year; particulates, nitrogen oxides and ozone associated with combustion emissions are very costly pollutants. Better air quality in urban environments is one of the reasons for countries to work together to reduce greenhouse gas emissions through the Paris Agreement on Climate Change. There are many potential benefits associated with limiting climate change. In the recent past, the concentrations of greenhouse gases in the atmosphere have been increasing and the number of weather and climate disasters with costs over $1 billion has been increasing. The average global temperature set new record highs in 2014, 2015, and 2016. To reduce greenhouse gas emissions, the transition to electric vehicles and electricity generation using renewable energy must take place in accord with the goals of the Paris Agreement on Climate Change. This work reviews progress and identifies some of the health benefits associated with reducing combustion emissions. © 2017 American Institute of Chemical Engineers Environ Prog, 36: 982-988, 2017.

  7. Is the global rise of asthma an early impact of anthropogenic climate change?

    Directory of Open Access Journals (Sweden)

    Paul John Beggs

    Full Text Available The increase in asthma incidence, prevalence, and morbidity over recent decades presents a significant challenge to public health. Pollen is an important trigger of some types of asthma, and both pollen quantity and season depend on climatic and meteorological variables. Over the same period as the global rise in asthma, there have been considerable increases in atmospheric carbon dioxide concentration and global average surface temperature. We hypothesize anthropogenic climate change as a plausible contributor to the rise in asthma. Greater concentrations of carbon dioxide and higher temperatures may increase pollen quantity and induce longer pollen seasons. Pollen allergenicity can also increase as a result of these changes in climate. Exposure in early life to a more allergenic environment may also provoke the development of other atopic conditions, such as eczema and allergic rhinitis. Although the etiology of asthma is complex, the recent global rise in asthma could be an early health effect of anthropogenic climate change.

    This paper describes the removal technique of gases such as CO2, SO2 and NOx which have the deep relation to the maintenance of global environment. This paper describes partially r SO2 and NOx which are the primary cause of acid rain. As for the removal of CO2 generated from fixed sources (thermal power stations and others), the separation technique and isolation-fixation technique have been researched on and developed. Of the separation method, the effect of the chemical absorption method and the adsorption method is proved with the preceding experiments. The isolation method is differently researched on as to store under deep sea or ground but may be urgent and temporary. The fixation of CO2 is a serious global problem which relates to the afforestation and forests. The fixation which uses coral reefs in ocean as the absorption source has a potential. As for the processing of substances causing acid rain, the desulfurization from petroleum and the flue gas desulfurization have the excellent results. The improvement of combustion method or the flue gas denitrification at the fixed sources are used to remove NOx. The removal of NOx from all diesel cars is difficult compared with the exhaust gas cleaning of gasoline cars and is not commercialized. 11 refs., 1 fig., 2 tabs.

  10. Robust Hadley Circulation Changes and Increasing Global Dryness Due to CO2 Warming from CMIP-5 Model Projections

    Lau, William K. M.; Kim, K. M.

    2015-01-01

    In this paper, we investigate changes in the Hadley Circulation (HC) and their connections to increased global dryness under CO2 warming from CMIP-5 model projections. We find a strengthening of the ascending branch of the HC manifested in a deep-tropics squeeze (DTS), i.e., a deepening and narrowing of the convective zone, increased high clouds, and a rise of the level of maximum meridional mass outflow in the upper troposphere (200-100 hectopascals) of the deep tropics. The DTS induces atmospheric moisture divergence, reduces tropospheric relative humidity in the tropics and subtropics, in conjunction with a widening of the subsiding branches of the HC, resulting in increased frequency of dry events in preferred geographic locations worldwide. Among water cycle parameters examined, global dryness has the highest signal-to-noise ratio. Our results provide scientific bases for inferring that the observed tend of prolonged droughts in recent decades is likely attributable to greenhouse warming.

    Energy Technology Data Exchange (ETDEWEB)

    Akbari, Hashem; Menon, Surabi; Rosenfeld, Arthur

    2007-05-22

    In many urban areas, pavements and roofs constitute over 60% of urban surfaces (roof 20-25%, pavements about 40%). The roof and the pavement albedo can be increased by about 0.25 and 0.10, respectively, resulting in a net albedo increase for urban areas of about 0.1. Many studies have demonstrated building cooling-energy savings in excess of 20% upon raising roof reflectivity from an existing 10-20% to about 60%. We estimate U.S. potential savings in excess of $1 billion (B) per year in net annual energy bills. Increasing albedo of urban surfaces can reduce the summertime urban temperature and improve the urban air quality. Increasing the urban albedo has the added benefit of reflecting more of the incoming global solar radiation and countering the effect of global warming. We estimate that increasing albedo of urban areas by 0.1 results in an increase of 3 x 10{sup -4} in Earth albedo. Using a simple global model, the change in air temperature in lowest 1.8 km of the atmosphere is estimated at 0.01K. Modelers predict a warming of about 3K in the next 60 years (0.05K/year). Change of 0.1 in urban albedo will result in 0.01K global cooling, a delay of {approx}0.2 years in global warming. This 0.2 years delay in global warming is equivalent to 10 Gt reduction in CO2 emissions.

  16. The increase in fatigue crack growth rates observed for Zircaloy-4 in a PWR environment

    2018-02-01

    Cyclic stresses produced during the operation of nuclear reactors can result in the extension of cracks by processes of fatigue. Although fatigue crack growth rate (FCGR) data for Zircaloy-4 in air are available, little testing has been performed in a PWR primary water environment. Test programs have been performed by Gee et al., in 1989 and Picker and Pickles in 1984 by the UK Atomic Energy Authority, and by Wisner et al., in 1994, that have shown an enhancement in FCGR for Zircaloy-2 and Zircaloy-4 in high-temperature water. In this work, FCGR testing is performed on Zircaloy-4 in a PWR environment in the hydrided and non-hydrided condition over a range of stress-intensity. Measurements of crack extension are performed using a direct current potential drop (DCPD) method. The cyclic rate in the PWR primary water environment is varied between 1 cycle per minute to 0.1 cycle per minute. Faster FCGR rates are observed in water in comparison to FCGR testing performed in air for the hydrided material. Hydrided and non-hydrided materials had similar FCGR values in air, but the non-hydrided material exhibited much lower rates of FCGR in a PWR primary water environment than for hydrided material. Hydrides are shown to exhibit an increased tendency for cracking or decohesion in a PWR primary water environment that results in an enhancement in FCGR values. The FCGR in the PWR primary water only increased slightly with decreasing cycle frequency in the range of 1 cycle per minute to 0.1 cycle per minute. Comparisons between the FCGR in water and air show the enhancement from the PWR environment is affected by the applied stress intensity.

The GEMS probes are neutrally buoyant and carried passively by the wind at predetermined levels. Each probe contains on-board satellite communication, power generation, processing, and geolocation capabilities. ENSCO has partnered with the National Aeronautics and Space Administration’s Kennedy Space Center (KSC Weather Office for a project called GEMS Test Operations in the Natural Environment (GEMSTONE. The goal of the GEMSTONE project was to build and field-test a small system of prototype probes in the Earth’s atmosphere. This paper summarizes the 9-month GEMSTONE project (Sep 2006 – May 2007 including probe and system engineering as well as experiment design and data analysis from laboratory and field tests. These tests revealed issues with reliability, sensor accuracy, electronics miniaturization, and sub-system optimization. Nevertheless, the success of the third and final free flight test provides a solid foundation to move forward in follow on projects addressing these issues as highlighted in the technology roadmap for future GEMS development.

    This is an editorial overview of the Siberia Integrated Regional Study (SIRS), which is a large-scale investigation of ongoing and future environmental change in Siberia and its relationship to global processes, approaches, existing challenges and future direction. Introduction The SIRS is a mega-project within the Northern Eurasia Earth Science Partnership Initiative (NEESPI), which coordinates interdisciplinary, national and international activities in Northern Eurasia that follow the Earth System Science Program (ESSP) approach. Under the direction of the International Geosphere-Biosphere Program (IGBP), SIRS is one of the Integrated Regional Studies (IRS) that aims to investigate environmental change in Siberia under the current environment of global change, and the potential impact on Earth system dynamics [1]. The regions of interest are those that may function as 'choke or switch points' for the global Earth system, where changes in regional biophysical, biogeochemical and anthropogenic components may have significant consequences for the Earth system at the global scale. Siberia is a large and significant region that may compel change [2]. Regional consequences of global warming (e.g. anomalous increases in cold season temperatures) have already been documented for Siberia [3]. This result is also supported by climate modeling results for the 20th-22nd centuries [4]. Future climatic change threatens Siberia with the shift of permafrost boundaries northward, dramatic changes in land cover (redistribution among boreal forest, wetlands, tundra, and steppe zones often precipitated by fire regime change) and the entire hydrological regime of the territory [5-8]. These processes feed back to and influence climate dynamics through the exchange of energy, water, greenhouse gases and aerosols [9]. Even though there have been a handful of national and international projects focused on the Siberian environment, scientists have minimal knowledge about the processes

However, it remains challenging for them to actually capture that value using traditional Intellectual Property (IP) tools. In this paper, we document the strong growth...... in patents, trademarks, and industrial designs used by firms to protect their IP globally. We then show that IP protection remains fragmented; the quality of IP applications might be questionable; and developing a comprehensive IP footprint worldwide is very costly.

    Increasing concentrations of CO2 and other greenhouse gases in the atmosphere can be directly related to global warming. In terms of human health, because a major cause of increasing atmospheric concentrations of CO2 is the increased combustion of fossil fuels, global warming also may result in increases in air pollutants, acid deposition, and exposure to ultraviolet (UV) radiation. To understand better the impacts of global warming phenomena on human health, this review emphasizes the processes that are responsible for the greenhouse effect, air pollution, acid deposition, and increased exposure to UV radiation.

    , especially farming traditions in small-scale, non-industrial societies, has been based not only on the technologies that are "friendly" to Nature, but also (and first of all) on the perception that soil (earth) is the source of all life. This sort of perception was particularly widespread among peoples of pre-industrial societies. The problem of searching for a way to increase long-term productivity in food grain production is complicated. This problem is of global importance for today and the future. The active interest of Modern society in the Folk experiences of using the Nature to achieve sustainable economies is yet to come, but we have much to learn from these small-scale non-industrial societies. Food production needs to be increased. At the same time, the fertility of the soil must be maintained. Achieving a balance between these two necessities is the problem. Changing the present modern human outlook from its egocentric position to one that understands and respects the natural environment, based on ideas of "ecological ethics", looks especially complex, and is directly connected with the problem of forming a new culture. Actually, the global ecological crisis and related ecological problems take priority and the transition to a new model of thinking promises to be accelerated. In this context, making use of Folk heritage, Folk knowledge and experience in observing Nature and using Nature to achieve harmonious interrelations in a "Nature - Society" system, and for the elaboration of a change of attitudes is quite important for modern society on a Global level to achieve ways of Sustainability. Lucius Seneca maintains that subjugation of a Nature is possible only if obeying to Nature.

    Carbon dioxide concentrations in the surface ocean are increasing owing to rising CO2 concentrations in the atmosphere. Higher CO2 levels are predicted to affect essential physiological processes of many aquatic organisms, leading to widespread impacts on marine diversity and ecosystem function, especially when combined with the effects of global warming. Yet the ability for marine species to adjust to increasing CO2 levels over many generations is an unresolved issue. Here we show that ocean conditions projected for the end of the century (approximately 1,000μatm CO2 and a temperature rise of 1.5-3.0°C) cause an increase in metabolic rate and decreases in length, weight, condition and survival of juvenile fish. However, these effects are absent or reversed when parents also experience high CO2 concentrations. Our results show that non-genetic parental effects can dramatically alter the response of marine organisms to increasing CO2 and demonstrate that some species have more capacity to acclimate to ocean acidification than previously thought.

  10. A hydroclimatic model of global fire patterns

    Boer, Matthias

    2015-04-01

    Satellite-based earth observation is providing an increasingly accurate picture of global fire patterns. The highest fire activity is observed in seasonally dry (sub-)tropical environments of South America, Africa and Australia, but fires occur with varying frequency, intensity and seasonality in almost all biomes on Earth. The particular combination of these fire characteristics, or fire regime, is known to emerge from the combined influences of climate, vegetation, terrain and land use, but has so far proven difficult to reproduce by global models. Uncertainty about the biophysical drivers and constraints that underlie current global fire patterns is propagated in model predictions of how ecosystems, fire regimes and biogeochemical cycles may respond to projected future climates. Here, I present a hydroclimatic model of global fire patterns that predicts the mean annual burned area fraction (F) of 0.25° x 0.25° grid cells as a function of the climatic water balance. Following Bradstock's four-switch model, long-term fire activity levels were assumed to be controlled by fuel productivity rates and the likelihood that the extant fuel is dry enough to burn. The frequency of ignitions and favourable fire weather were assumed to be non-limiting at long time scales. Fundamentally, fuel productivity and fuel dryness are a function of the local water and energy budgets available for the production and desiccation of plant biomass. The climatic water balance summarizes the simultaneous availability of biologically usable energy and water at a site, and may therefore be expected to explain a significant proportion of global variation in F. To capture the effect of the climatic water balance on fire activity I focused on the upper quantiles of F, i.e. the maximum level of fire activity for a given climatic water balance. Analysing GFED4 data for annual burned area together with gridded climate data, I found that nearly 80% of the global variation in the 0.99 quantile of F

    The Urban population of developing countries is predicted to rise from one third in 1990 to over 50% by 2025. In 1950 the world's total urban population was 734 million, of whom 448 million were living in developed countries and remaining 286 were in developing region. The total population on earth is predicted to increase by more than one billion people within the next 15 years, reaching 8.5 billion in 2030, and to increase further to 9.7 billion in 2050 and 11.2 billion by 2100. Looking at the ever increasing urbanization.In 2016, an estimated 54.5 per cent of the world's populations inhabited in urban region. By 2030, urban areas are projected to shelter 60 per cent of people worldwide and one in every three people will live in cities with at least half a million inhabitants.On the basis of these figures and other global trends, it would appear that Africa and Asia will have the highest share of world's urban growth in next 25 years, resulting consideration rise of large number of metropolitan cities and towns. Therefore issues related to urban climate change will be important for socio economic development for urban transformation through environmental sustainability.The information and communication systems plays an important role in achieving the social sustainability through environmental sustainability for urban transformation. This presentation aims to start the Global initiatives on the problem identifications in environment education for global transformation, education for socio-economic and environmental sustainability due to urbanization in 2050 to investigate problems related to social-economic risks and management issues resulting from urbanization to aid mitigation planning in globalized world and to educate scientists and local populations to form a basis for sustainable solutions in environment learning.The presentation aims to assess the potential of information and communication technology for environment education,both within different

    Full Text Available The problem of the globalization of risks is examined in this article. Based on the World Economic Forum (WEF report on global risks 2015-2017, the impact of global risks on the social and economic development of countries is examined. Economic, social, environmental, geopolitical, technological risks are analyzed in a coordinated fashion. The article notes that the main risks are in the field of environment and ecology. Anthropogenic pressure amplification, scientific and technological advance have an influence on the natural environment. The risks of infrastructure and environmental damage in danger zone are increased because of the growth of the frequency of extreme weather events. The measures for the protection of the environment are examined. The unilateral approach to solving international issues, instead of the collective efforts of the international community; the deployment of weapons of mass destruction (nuclear, chemical, biological and technologies for the production of radioactive materials; escalation of economic and resource nationalization (the desire of States to expropriate or restrict the export of important for the world economy of resources, etc. promote the increasing geopolitical risks.Economic risks include the risk in terms of their likelihood their impact on the macroeconomic, as from the financial systems and infrastructure to price volatility and regulatory issues. Social risks are the risks relating to instability of population dynamics, social crises and human survival.Technological risks include such problems as software defects, failure of important information systems, upon which today industrial production is depended, the services and communications sector; the escalation of large-scale cyber-attacks; theft of electronic information and the illegal usage of personal data. The trends that can intensify the global risks or to change the correlation between them are analyzed in this article.

  13. The impact of global warming on the automotive industry

    Science.gov (United States)

    Hannappel, Ralf

    2017-08-01

    One cause of global warming of the earth's atmosphere is the emission of human made gases (methane, CO2, nitrous oxygen, etc.) into the environment. Of the total global CO2 emissions the transportation sector contributes to about 14%. In order to control the emissions of the automotive sector, in all major countries (USA, Europe, China, Japan) of the world, tough emissions targets were being set to reduce the vehicle traffic's contribution of CO2. These are derived from the global climate conference' target to limit the maximum temperature increase of the earth of 2 degrees Celsius until 2100. In order to achieve these stringent targets the automotive industry will face a major change in its drivetrain. It will move from combustion to electrical engines. The technical realization of these engines will most likely be battery and fuel cell driven propulsion systems. In order to achieve that transition a major effort is required in 4 industrial areas, i.e. growing electrical charging infrastructure, lowering battery cost, increasing the battery-electric vehicle ranges and developing new environmental friendly hydrogen production methods.

  14. From global agenda-setting to domestic implementation: successes and challenges of the global health network on tobacco control.

    Gneiting, Uwe

    2016-04-01

    Global policy attention to tobacco control has increased significantly since the 1990 s and culminated in the first international treaty negotiated under the auspices of the World Health Organization--the Framework Convention on Tobacco Control (FCTC). Although the political process that led to the creation of the FCTC has been extensively researched, the FCTC's progression from an aspirational treaty towards a global health governance framework with tangible policy effects within FCTC member countries has not been well-understood to date. This article analyses the role of the global health network of tobacco control advocates and scientists, which formed during the FCTC negotiations during the late 1990 s, in translating countries' commitment to the FCTC into domestic policy change. By comparing the network's influence around two central tobacco control interventions (smoke-free environments and taxation), the study identifies several scope conditions, which have shaped the network's effectiveness around the FCTC's implementation: the complexity of the policy issue and the relative importance of non-health expertise, the required scope of domestic political buy-in, the role of the general public as network allies, and the strength of policy opposition. These political factors had a greater influence on the network's success than the evidence base for the effectiveness of tobacco control interventions. The network's variable success points to a trade-off faced by global health networks between their need to maintain internal cohesion and their ability to form alliances with actors in their social environment.

    Fluvial sediment export from small mountainous rivers in Oceania has global biogeochemical significance affecting the turnover rate and export of terrestrial carbon, which might be speeding up at the recognized conditions of increased rainfall intensity. In this study, the historical runoff and sediment export from 16 major rivers in Taiwan are investigated and separated into an early stage (1970-1989) and a recent stage (1990-2010) to illustrate the changes of both runoff and sediment export. The mean daily sediment export from Taiwan Island in the recent stage significantly increased by >80% with subtle increase in daily runoff, indicating more sediment being delivered to the ocean per unit of runoff in the recent stage. The medians of the runoff depth and sediment yield extremes (99.0-99.9 percentiles) among the 16 rivers increased by 6.5%-37% and 62%-94%, respectively, reflecting the disproportionately magnified response of sediment export to the increased runoff. Taiwan is facing increasing event rainfall intensity which has resulted in chain reactions on magnified runoff and sediment export responses. As the globe is warming, rainfall extremes, which are proved to be temperature-dependent, very likely intensify runoff and trigger more sediment associated hazards. Such impacts might occur globally because significant increases of high-intensity precipitation have been observed not only in Taiwan but over most land areas of the globe.

    Global warming caused by increase in atmospheric CO 2 concentration has been the focus of many recent global energy studies. CO 2 is emitted to the atmosphere mainly from the combustion of fossil fuels. This means that global warming is fundamentally a problem of the global energy system. An analysis of the findings of recent global energy studies is made in this report. The results are categorized from the viewpoint of concern about global warming. The analysis includes energy use and CO 2 emissions, measures taken to restrain CO 2 emissions and the cost of such measure, and suggestions for long term global energy generation. Following this comparative analysis, each of the studies is reviewed in detail. (author) 63 refs

    Full Text Available The environment is increasingly being recognised for the role it might play in the global spread of clinically-relevant antibiotic resistance. Environmental regulators monitor and control many of the pathways responsible for the release of resistance-driving chemicals into the environment (e.g., antimicrobials, metals, biocides. Hence, environmental regulators should be contributing significantly to the development of global and national antimicrobial resistance (AMR action plans. It is argued that the lack of environment-facing mitigation actions included in existing AMR action plans is likely a function of our poor fundamental understanding of many of the key issues. Here, we aim to present the problem with AMR in the environment through the lens of an environmental regulator, using the Environment Agency (England’s regulator as an example from which parallels can be drawn globally. The issues that are pertinent to environmental regulators are drawn out to answer: What are the drivers and pathways of AMR? How do these relate to the normal work, powers and duties of environmental regulators? What are the knowledge gaps that hinder the delivery of environmental protection from AMR? We offer several thought experiments for how different mitigation strategies might proceed. We conclude that: 1 AMR Action Plans do not tackle all the potentially relevant pathways and drivers of AMR in the environment; and 2 AMR Action Plans are deficient, in part, because the science to inform policy is lacking and this needs to be addressed.

  19. Global Banking System Regulatory Environment

    Full Text Available The international and domestic experience shows that the main factors of financial destabilization during the financial crises are in the banking sector. The article reveals that the vulnerability of the financial system is connected with functions, deposit and credit transactions, risks distribution and ensuring liquidity; banks act as a major factor in stabilisation measures in the current context of globalization processes, since the economic stability of banking activities relates directly to all the entities and only stable banking system can withstand the crisis phenomena. Therefore, as a result of the analysis, it is proved that not only reduction of risks of banks is needed, but also introduction of the effective supervision system over implementation of the requirements and standards to prevent these risks. According to modern international approaches, banks use the so-called prudential supervision, which is based on the risk management assessment policy on the part of the Bank’s management, and regulatory bodies contribute to implementation of such policy. The authors have concluded that not only modern specificity of banks, but also the impact of supervision systems and regulation of modern trends in development of the banking should be analysed. Application of the general regulatory principles and banking risks methodology is required. The task of supervision is distribution of reliable risk management practices in the banking system, taking into account national peculiarities of development.

  20. Synthetic polymers in the marine environment: a rapidly increasing, long-term threat.

    2008-10-01

    Synthetic polymers, commonly known as plastics, have been entering the marine environment in quantities paralleling their level of production over the last half century. However, in the last two decades of the 20th Century, the deposition rate accelerated past the rate of production, and plastics are now one of the most common and persistent pollutants in ocean waters and beaches worldwide. Thirty years ago the prevailing attitude of the plastic industry was that "plastic litter is a very small proportion of all litter and causes no harm to the environment except as an eyesore" [Derraik, J.G.B., 2002. The pollution of the marine environment by plastic debris: a review. Mar. Pollut. Bull. 44(9), 842-852]. Between 1960 and 2000, the world production of plastic resins increased 25-fold, while recovery of the material remained below 5%. Between 1970 and 2003, plastics became the fastest growing segment of the US municipal waste stream, increasing nine-fold, and marine litter is now 60-80% plastic, reaching 90-95% in some areas. While undoubtedly still an eyesore, plastic debris today is having significant harmful effects on marine biota. Albatross, fulmars, shearwaters and petrels mistake floating plastics for food, and many individuals of these species are affected; in fact, 44% of all seabird species are known to ingest plastic. Sea turtles ingest plastic bags, fishing line and other plastics, as do 26 species of cetaceans. In all, 267 species of marine organisms worldwide are known to have been affected by plastic debris, a number that will increase as smaller organisms are assessed. The number of fish, birds, and mammals that succumb each year to derelict fishing nets and lines in which they become entangled cannot be reliably known; but estimates are in the millions. We divide marine plastic debris into two categories: macro, >5 mm and micro, plastic micro-debris by filter feeders at the base of the food web is known to occur, but has not been quantified

  3. Evaluating The Global Inventory of Planetary Analog Environments on Earth: An Ontological Approach

    Science.gov (United States)

    Conrad, P. G.

    2010-12-01

    Introduction: Field sites on Earth are routinely used to simulate planetary environments so that we can try to understand the evidence of processes such as sedimentary deposition, weathering, evolution of habitable environments, and behavior of spacecraft and instrumentation prior to selection of mission architectures, payload investigations and landing sites for in situ exploration of other planets. The rapid evolution of astrobiology science drivers for space exploration as well as increasing capability to explore planetary surfaces in situ has led to a proliferation of declarations that various Earth environments are analogs for less accessible planetary environments. We have not yet progressed to standardized measures of analog fidelity, and the analog value of field sites can be variable de-pending upon a variety of factors. Here we present a method of evaluating the fidelity and hence utility of analog environments by using an ontological approach to evaluating how well the analogs work. The use of ontologies as specification constructs is now quite common in artificial intelligence, systems engineering, business development and various informatics systems. We borrow from these developments just as they derive from the original use of ontology in philosophy, where it was meant as a systematic approach to describing the fundamental elements that define “being,” or existence [1]. An ontology is a framework for the specification of a concept or domain of interest. The knowledge regarding that domain, eg., inventory of objects, hierarchical classes, relationships and functions is what describes and defines the domain as a declarative formalism [2]. In the case of planetary environments, one can define a list of fundamen-tal attributes without which the domain (environment) in question must be defined (classified) otherwise. In particu-lar this is problematic when looking at ancient environments because of their alteration over time. In other words, their

    The second annual report describes specific environmental strategies and environmental lending in the Bank's four operational regions: Africa; Asia; Europe, Middle East, and North Africa; and Latin America and the Caribbean. It details the Bank's progress in eight environmental categories: energy and the environment, pollution, urban environment, water resources management, forest and land management, social and cultural, environmental economics, and the global environment. One chapter is devoted exclusively to tropical forests, studying ways in which the Bank is dealing with deforestation as a part of the constant review of its forest policies. Suggestions are made for decreasing the degradation of tropical forests while meeting demands for forest products. This chapter reflects a shift in Bank emphasis from commercial ventures to conservation measures. The publication reports on other initiatives by the Bank during fiscal 1991, including the launching of the Global Environment Facility (GEF)--a pilot program to oversee reduction of global warming, preservation of biological diversity, protection of international waters, and prevention of ozone depletion

    In response to increasing concentrations of atmospheric CO2, high-end general circulation models (GCMs) simulate an accumulation of energy at the top of the atmosphere not through a reduction in outgoing longwave radiation (OLR)—as one might expect from greenhouse gas forcing—but through an enhancement of net absorbed solar radiation (ASR). A simple linear radiative feedback framework is used to explain this counterintuitive behavior. It is found that the timescale over which OLR returns to its initial value after a CO2 perturbation depends sensitively on the magnitude of shortwave (SW) feedbacks. If SW feedbacks are sufficiently positive, OLR recovers within merely several decades, and any subsequent global energy accumulation is because of enhanced ASR only. In the GCM mean, this OLR recovery timescale is only 20 y because of robust SW water vapor and surface albedo feedbacks. However, a large spread in the net SW feedback across models (because of clouds) produces a range of OLR responses; in those few models with a weak SW feedback, OLR takes centuries to recover, and energy accumulation is dominated by reduced OLR. Observational constraints of radiative feedbacks—from satellite radiation and surface temperature data—suggest an OLR recovery timescale of decades or less, consistent with the majority of GCMs. Altogether, these results suggest that, although greenhouse gas forcing predominantly acts to reduce OLR, the resulting global warming is likely caused by enhanced ASR.

    Tree growth has been reported to increase in response to recent global climate change in controlled and semi-controlled experiments, but few studies have reported response of tree growth to increased temperature and atmospheric carbon dioxide (CO₂) concentration in natural environments. This study addresses how recent global climate change has affected height growth of trembling aspen (Populus tremuloides Michx) and black spruce (Picea mariana Mill B.S.) in their natural environments. We sampled 145 stands dominated by aspen and 82 dominated by spruce over the entire range of their distributions in British Columbia, Canada. These stands were established naturally after fire between the 19th and 20th centuries. Height growth was quantified as total heights of sampled dominant and co-dominant trees at breast-height age of 50 years. We assessed the relationships between 50-year height growth and environmental factors at both spatial and temporal scales. We also tested whether the tree growth associated with global climate change differed with spatial environment (latitude, longitude and elevation). As expected, height growth of both species was positively related to temperature variables at the regional scale and with soil moisture and nutrient availability at the local scale. While height growth of trembling aspen was not significantly related to any of the temporal variables we examined, that of black spruce increased significantly with stand establishment date, the anomaly of the average maximum summer temperature between May-August, and atmospheric CO₂ concentration, but not with the Palmer Drought Severity Index. Furthermore, the increase of spruce height growth associated with recent climate change was higher in the western than in eastern part of British Columbia. This study demonstrates that the response of height growth to recent climate change, i.e., increasing temperature and atmospheric CO₂ concentration, did not only differ with tree species, but

    Globalization has increased the demand for international experiences in medical education. International experiences improve medical knowledge, clinical skills, and self-development; influence career objectives; and provide insights on ethical and societal issues. However, global health rotations can end up being no more than tourism if not structured to foster personal transformation and global citizenship. We conducted a qualitative assessment of trainee-reported critical incidents to more deeply understand the impact of our global health experience on trainees. A cross-sectional survey was administered to trainees who had participated in a 2-month elective in Kenya from January 1989 to May 2013. We report the results of a qualitative assessment of the critical incident reflections participants (n = 137) entered in response to the prompt, "Write about one of your most memorable experiences and explain why you chose to describe this particular one." Qualitative analyses were conducted using thematic analysis and crystallization immersion analytic methods based on the principles of grounded theory, employing a constructivists' research paradigm. Four major themes emerged. These themes were Opening Oneself to a Broader World View; Impact of Suffering and Death; Life-Changing Experiences; and Commitment to Care for the Medically Underserved. Circumstances that learners encounter in the resource-scarce environment in Kenya are eye-opening and life-changing. When exposed to these frame-shifting circumstances, students elaborate on or transform existing points of view. These emotionally disruptive experiences in an international health setting allowed students to enter a transformational learning process with a global mind. Students can see the world as an interdependent society and develop the capacity to advance both their enlightened self-interest and the interest of people elsewhere in the world as they mature as global citizens. Medical schools are encouraged to

    Aerosols play a crucial role in the climate system, affecting incoming radiation and cloud formation. Based on a modelling framework that couples ecosystem processes with the atmospheric transfer of radiation, we analyze the effect of aerosols on surface incoming radiation, gross primary productivity (GPP), water losses from ecosystems through evapotranspiration (ET) and ecosystem water use efficiency (WUE, defined as GPP/ET) for 2003–2010 and validate them at global FLUXNET sites. The total diffuse radiation increases under relatively low or intermediate aerosol loadings, but decreases under more polluted conditions. We find that aerosol-induced changes in GPP depend on leaf area index, aerosol loading and cloudiness. Specifically, low and moderate aerosol loadings cause increases in GPP for all plant types, while heavy aerosol loadings result in enhancement (decrease) in GPP for dense (sparse) vegetation. On the other hand, ET is mainly negatively affected by aerosol loadings due to the reduction in total incoming radiation. Finally, WUE shows a consistent rise in all plant types under increasing aerosol loadings. Overall, the simulated daily WUE compares well with observations at 43 eddy-covariance tower sites (R2=0.84 and RMSE=0.01gC (kg H2O)-1) with better performance at forest sites. In addition to the increasing portions of diffuse light, the rise in WUE is also favored by the reduction in radiation- and heat-stress caused by the aerosols, especially for wet and hot climates.

    2009-01-01

    The human interference in the environment and the consequent climate change is today a consensus. The climate change can be local, regional and global. The global climate change is mainly caused by the greenhouse gases, and consequently the climate change intervenes in the environment. The interference cycle emerges in several forms and results in several consequences. However, the Global Warming has certainly the most import global impact. The main cause of the increase in the temperature (Greenhouse Effect) is the intensive use of the fossil fuels. Thus, to minimize the climatic changes actions are necessary to reduce, to substitute and to use with more efficient the fossil fuels. Looking at the past, the old agriculturists may have released greenhouse gases since thousand years ago, thus, modifying slowly but in significant form the earth climate much before the Industrial Age. If this theory is confirmed, its consequences would be decisive for the man history in the planet. For example, in parts of the North America and Europe the current temperatures could be even four Celsius degrees smaller. This change in temperature is enough to hinder agricultural used of these regions and consequently to diminish the human development. The main focus of this work is to perform a retrospective in some of civilizations who collapse due to environmental problems and make a historical description of the human activities (agriculture and livestock) since the primordium of the man up to the Industrial Age, aiming at the man interference on the natural dynamics of the global climate and the environment. This work will show through data comparisons and inferences that the gases emissions from these activities had a significant magnitude comparatively by the emissions after the Industrial Age. It is also demonstrated that the climate and environment interference was inevitable because the human evolution was caused by these activities. Another important point of this work is to

    Global environmental leader (GEL) education programme at graduate school for international development and cooperation (IDEC) in Hiroshima University is an education and training programme for graduate students especially from developing countries in Asian region to build and enhance their ability to become international environmental leaders. Through this programme, they will participate in regular course works and other activities to learn how to cope with the various environment and resource management issues from global to regional scales toward a low-carbon society via multi-disciplinary approaches considering sustainable development and climate change. Under this GEL programme, there are five different research sub-groups as follows assuming a cause-effect relationship among interacting components of social, economic, and environmental systems; 1) urban system design to prevent global warming, 2) wise use of biomass resources, 3) environmental impact assessment, 4) policy and institutional design, and 5) development of environmental education programs. Candidate students of GEL programme belong to one of the five research sub-groups, perform their researches and participate in many activities under the cross-supervisions from faculty members of different sub-groups. Under the third research group for environmental impact assessment, we use numerical models named as regional environment simulator (RES) as a tool for research and education for assessing the environmental impacts due to natural hazards. Developed at IDEC, Hiroshima University, RES is a meso-scale numerical model system that can be used for regional simulation of natural disasters and environmental problems caused by water and heat circulation in the atmosphere, hydrosphere, and biosphere. RES has three components: i) atmosphere-surface waves-ocean part, ii) atmosphere-land surface process-hydrologic part, and iii) coastal and estuarine part. Each part is constructed with state-of-the-art public

  17. The oceanic cycle and global atmospheric budget of carbonyl sulfide

    Energy Technology Data Exchange (ETDEWEB)

    Weiss, P.S.

    1994-12-31

    A significant portion of stratospheric air chemistry is influenced by the existence of carbonyl sulfide (COS). This ubiquitous sulfur gas represents a major source of sulfur to the stratosphere where it is converted to sulfuric acid aerosol particles. Stratospheric aerosols are climatically important because they scatter incoming solar radiation back to space and are able to increase the catalytic destruction of ozone through gas phase reactions on particle surfaces. COS is primarily formed at the surface of the earth, in both marine and terrestrial environments, and is strongly linked to natural biological processes. However, many gaps in the understanding of the global COS cycle still exist, which has led to a global atmospheric budget that is out of balance by a factor of two or more, and a lack of understanding of how human activity has affected the cycling of this gas. The goal of this study was to focus on COS in the marine environment by investigating production/destruction mechanisms and recalculating the ocean-atmosphere flux.

    Full Text Available Research Question (RQ: In the article we highlight the issue of whether Integration processes in the European Union are only a manifestation of these Globalization processes and if there are differences in the the old member States EU (15 and the new EU member states in changed micro and macro environment? Purpose: We wanted to determine how the old member States EU (15 and the new EU member states adapt to the new circumstances and other changes in the micro and macro environment. Method: Analysing complexity of the changes of the state of economic system, and complex fundamental global processes, which have been occurred in long period of time, need to supplement the pure scientific approach with other types of research work, more holistic approach, which is commonly used in Comparative economics. We have taken such an approach in this article. Results: In the article we studied the geopolitical changes in the micro and macro environment. We found that the development in the old EU member states EU-15 and in the new EU member states is different. EU havent addopted the harmonised economic policy which will solve the »North-South« problem and cross-state cultural consensus and find a way to operate systemically in global environment. Organization: The findings can be used to support undestanding of micro and macro envirnment of the companys and contribute for better strategic planning and design of the entire supply chain. Society: The findings can contribute to better understanding of integrative processes in the EU. Limitations/Future Research: The complexity of the problem and the dynamic changes in the functioning of the global market requires in-depth studiying of changes in the micro and macro environment of logistics companie

    A Global Environment Assessment (GEO) workshop was held in Brussels on September 15 and 16, 1998. During the preparation of policy-oriented reports of GEO, several gaps in data and expertise had been identified. The workshop elaborated on the issues where gaps had been signalled aimed to bring together scientists from different disciplines, representatives of the Directorate General XII and specialists from RIVM in integrated environmental assessment to locate information missing in UNEP's studies and make progress in filling up gaps. Research needs would be identified. The specific issues were categorised as: land-related issues, urban environment and implementation of policies. The workshop participants were able to identify several links between the activities for GEO and ongoing research in the context of the EU Research, Technology Development and the Demonstration programme. About 15 more specific research needs were formulated. For land-related issues, the following knowledge gaps and research implications were identified: (1) e.g. social and economic expertise in land-use analysis, (2) e.g. land-use planning and urban land use in integrated assessment, (3) modelling land degradation, and (4) modelling the driving forces of land degradation. For the urban environment, the major knowledge research areas identified from an integrative perspective were: (1) defining a core set of indicators for sustainable urban development, (2) quantifying the interlinkages between environmental stress and human health, (3) describing the effects of measures, (4) determining the role of institutional structures, and (5) ensuring data provision based on the physical city. Major problems were identified for implementation of policies that the degree of policy implementation is not often measured and that it is difficult to relate policy actions to changes in environmental pressures. In analysis it is first of all necessary to identify which definition of effectiveness will be

    BackgroundAntibiotic-resistant bacteria pose challenges to healthcare delivery systems globally; however, limited information is available regarding the prevalence and spread of such bacteria in the environment. The aim of this study was to compare the prevalence of antibiotic-resistant bacteria in large-bodied gulls (Larus spp.) at urban and remote locations in Southcentral Alaska to gain inference into the association between antibiotic resistance in wildlife and anthropogenically influenced habitats.MethodsEscherichia coli was cultured (n=115 isolates) from fecal samples of gulls (n=160) collected from a remote location, Middleton Island, and a more urban setting on the Kenai Peninsula.ResultsScreening of E. coli from fecal samples collected from glaucous-winged gulls (Larus glaucescens) at Middleton Island revealed 8% of isolates were resistant to one or more antibiotics and 2% of the isolates were resistant to three or more antibiotics. In contrast, 55% of E. coli isolates derived from fecal samples collected from large-bodied gulls (i.e. glaucous, herring [Larus argentatus], and potentially hybrid gulls) on the Kenai Peninsula were resistant to one or more antibiotics and 22% were resistant to three or more antibiotics. In addition, total of 16% of the gull samples from locations on the Kenai Peninsula harbored extended-spectrum cephalosporin-resistant E. coli isolates (extended-spectrum beta-lactamases [ESBL] and plasmid-encoded AmpC [pAmpC]), in contrast to Middleton Island where no ESBL- or pAmpC-producing isolates were detected.ConclusionOur findings indicate that increased prevalence of antibiotic resistance is associated with urban environments in Southcentral Alaska and presumably influenced by anthropogenic impacts. Further investigation is warranted to assess how migratory birds may maintain and spread antimicrobial-resistant bacteria of relevance to human and animal health.

    Paul, Varun G; Mormile, Melanie R

    2017-08-01

    Saline and hypersaline environments are known for their unique geochemical properties, microbial populations and aesthetic appeal. Microbial activities and a spectrum of diversity seen in hypersaline environments are distinct with many novel species being identified and reported on a regular basis. Many distinguishing characteristics about the adaptation, morphology, evolutionary history, and potential environmental and biotechnological applications of these organisms are continually investigated. An abundance of interdisciplinary activities and opportunities exist to explore and understand the importance of these environments that potentially hold promising solutions for current and future global issues. Therefore, it is critical to conserve these unique environments and limit the damage inflicted by anthropogenic influences. Increased salinization due to water diversions, undesired freshening, extensive mineral extraction, sewage effluents, pollution due to agricultural runoff and industrial processes, urbanization, and global climate change are factors negatively affecting hypersaline lakes and their surrounding environments. If these harmful effects continue to proceed at the current or even accelerated rates, irrevocable consequences for these environments will occur, resulting in the loss of potential opportunities to gain new knowledge of the biogeochemistry as well as beneficial microbial populations closely associated with these unique and interesting environments. © FEMS 2017.

    Global climate change (GCC) is likely to alter the degree of human exposure to pollutants and the response of human populations to these exposures, meaning that risks of pollutants could change in the future. The present study, therefore, explores how GCC might affect the different steps in the pathway from a chemical source in the environment through to impacts on human health and evaluates the implications for existing risk-assessment and management practices. In certain parts of the world, GCC is predicted to increase the level of exposure of many environmental pollutants due to direct and indirect effects on the use patterns and transport and fate of chemicals. Changes in human behavior will also affect how humans come into contact with contaminated air, water, and food. Dietary changes, psychosocial stress, and coexposure to stressors such as high temperatures are likely to increase the vulnerability of humans to chemicals. These changes are likely to have significant implications for current practices for chemical assessment. Assumptions used in current exposure-assessment models may no longer apply, and existing monitoring methods may not be robust enough to detect adverse episodic changes in exposures. Organizations responsible for the assessment and management of health risks of chemicals therefore need to be more proactive and consider the implications of GCC for their procedures and processes.

  8. Assessment of the Impact of Metropolitan-Scale Urban Planning Scenarios on the Moist Thermal Environment under Global Warming: A Study of the Tokyo Metropolitan Area Using Regional Climate Modeling

    Directory of Open Access Journals (Sweden)

    Asuka Suzuki-Parker

    2015-01-01

    Full Text Available Using a high-resolution regional climate model coupled with urban canopy model, the present study provides the first attempt in quantifying the impact of metropolitan-scale urban planning scenarios on moist thermal environment under global warming. Tokyo metropolitan area is selected as a test case. Three urban planning scenarios are considered: status quo, dispersed city, and compact city. Their impact on the moist thermal environment is assessed using wet-bulb globe temperature (WBGT. Future projections for the 2070s show a 2–4°C increase in daytime mean WBGT relative to the current climate. The urban scenario impacts are shown to be small, with a −0.4 to +0.4°C range. Relative changes in temperature and humidity as the result of a given urban scenario are shown to be critical in determining the sign of the WBGT changes; however, such changes are not necessarily determined by local changes in urban land surface parameters. These findings indicate that urban land surface changes may improve or worsen the local moist thermal environment and that metropolitan-scale urban planning is inefficient in mitigating heat-related health risks for mature cities like Tokyo.

    The growth of the world's population and related human activities are clearly leaving major effects on the environment and on the level of use of natural resources: forests are disappearing, air pollution is leading to acid rains, changes are occuring in the atmospheric ozone and global climate, more and more people lack access to reasonable safe supplies of water, soil pollution is becoming a problem, mineral and energy resources are increasingly being used. Producing more with less, producing more, polluting less, these are basic challenges that the world now faces. Low- and non-waste technologies are certainly one of the keys to those challenges.

  11. Can Better Outdoor Environments Lead to Cost Benefits in Assisted Living Facilities Through Increased Word-of-Mouth Referrals?

    This study explores how better outdoor environments may produce cost benefits for assisted living providers by raising occupancy levels through increased resident satisfaction and word-of-mouth referrals. Older adults who spend even minimal time outdoors may reap substantial health benefits. However, many existing outdoor areas in assisted living facilities are reportedly underutilized, in part because of design issues. Providers may be more willing to improve outdoor areas if they produce cost benefits for provider organizations. This study used data from a recent assisted living survey to assess the relationship between satisfaction with outdoor spaces, time spent outdoors, and resulting improvements in mood. A financial analysis was developed to estimate potential benefits from improved outdoor areas attributable to increased occupancy and decreased marketing costs associated with increased word-of-mouth referrals. Increasing resident satisfaction with outdoor areas (from approximately 29% to 96%) results in residents spending more time outdoors (increase of 1½ hours per week per resident) and improved psychological well-being (12% increase in feeling better). This greater overall satisfaction leads to 8% more residents willing to refer potential residents to their community. Because word-of-mouth referrals by current residents are a major factor in resident recruitment, improving outdoors areas leads to an estimated 4% increase in new residents, resulting in over $170,000 of increased revenue per year for a community of 100 residents. Improved outdoor space can provide substantial cost benefits for assisted living providers. Increasing resident well-being and satisfaction, and thereby generating additional word-of-mouth referrals, can result in higher occupancy levels.

    In order to serve for measures against global problems taken by Japan, joint research was carried out with overseas research organizations. The research project selected ten themes considering urgency, internationality and economic proliferation effect in areas to serve for solution of global environment problems. These themes include removal or emission control of greenhouse effect gases, measures against atmospheric environment problems such as acid rains and ozone layer destruction, prevention of ocean contamination, development and effective utilization of energies and resources. When the feedback of these themes to the NEDO projects is considered, the research achievements in relation with development of the acid rain monitoring system in particular support indirectly development of carbon dioxide fixation technologies. The research achievements in developing an environmentally friendly biomass energy manufacturing process and environmental effect evaluation thereon contribute as an effective process to carbon dioxide reduction using biomass as raw materials. The achievements in research of nonlinear interfacial properties and mixed phase turbulence of low-purity carbon dioxide bubbles contribute to a project related to storage of carbon dioxide in oceans.

    The Michigan Tech GlobalWatershed GK-12 Fellowship program bridges the gap between K-12 learning institutions and the scientific community with a focus on watershed research. Michigan Tech graduate students (fellows) work in tandem with teachers on the development of relevant hands-on, inquiry based lesson plans and activities based on their doctoral research projects in watershed science. By connecting students and teachers to state of the art academic research in watershed science, teachers are afforded a meaningful way in which to embed scientific research as a component of K-12 curricula, while mentoring fellows on the most pertinent and essential topics for lesson plan development. Fellows fulfill their vital responsibility of communicating their academic research to a broader public while fostering improved teaching and communication skills. A goal of the project is to increase science literacy among students so they may understand, communicate and participate in decisions made at local, regional, and global levels. The project largely works with schools located in Michigan's western Upper Peninsula but also partners with K-12 systems in Sonora, Mexico. While focusing on local and regional issues, the international element of the project helps expand student, teacher, and fellow worldviews and global awareness of watershed issues and creates meaningful partnerships. Lesson plans are available online and teacher workshops are held regularly to disseminate the wealth of information and resources available to the broader public. Evaluation results indicate that fellows' skill and confidence in their ability to communicate science increased as a results of their participation of the program, as well as their desire to communicate science in their future careers. Teachers' confidence in their capacity to present watershed science to their students increased, along with their understanding of how scientific research contributes to understanding of water

With the rapid increase of the global population there has been a trend for people to migrate into megacities and has caused the expansion of big city territories. This trend, coupled with the desire for a comfortable living environment, has resulted in numerous problems plaguing the megacity. This article proposes that a viable solution to the problems facing megacities is to create vertical layout environments. Potential options for creating vertical layout environments are set out below including the construction of buildings with atriums. Further, the article puts forth suggested spatial organization of the environment as well as optimal landscaping of high-rise buildings and constructions for the creation of vertical layout environments. Finally, the persuasive reasons for the adoption of vertical layout environments is that it will decrease the amount of developed urban areas, decrease traffic and increase environmental sustainability.

    2018-03-01

    Full Text Available The regularities of transforming the environment of multinational enterprises are considered from the standpoint of the general system theory. Tendencies of growth of pressure of the international competition on the Ukrainian branch markets have been identified. Special attention is paid to the nature of interaction between global and local forces that determine the type of operating environment. On the basis of the allocated nine main directions of transformational processes at the enterprise, the matrix of decision-making on ways of integration of the enterprise in business space has been proposed. Attention is focused on the problem of the local and the global, which is manifested in the decisions on standardization and adaptation of strategies. The dependence of degree of adaptation and standardization of strategic decisions from the correlation of local and global factors of environment, from the type of environment, in which a multinational enterprise works, has been characterized. The national and international aspects of both the internal networks and the external cooperation agreements, advantages of the joint innovative efforts in the form of cooperation are researched. The international importance of multinational enterprises is very topical, as the interaction between own capital and external sources increases the innovation potential of enterprises.

  20. Improvements in crop water productivity increase water sustainability and food security—a global analysis

    Brauman, Kate A; Foley, Jonathan A; Siebert, Stefan

    Irrigation consumes more water than any other human activity, and thus the challenges of water sustainability and food security are closely linked. To evaluate how water resources are used for food production, we examined global patterns of water productivity—food produced (kcal) per unit of water (l) consumed. We document considerable variability in crop water productivity globally, not only across different climatic zones but also within climatic zones. The least water productive systems are disproportionate freshwater consumers. On precipitation-limited croplands, we found that ∼40% of water consumption goes to production of just 20% of food calories. Because in many cases crop water productivity is well below optimal levels, in many cases farmers have substantial opportunities to improve water productivity. To demonstrate the potential impact of management interventions, we calculated that raising crop water productivity in precipitation-limited regions to the 20th percentile of productivity would increase annual production on rainfed cropland by enough to provide food for an estimated 110 million people, and water consumption on irrigated cropland would be reduced enough to meet the annual domestic water demands of nearly 1.4 billion people.

  1. The imprint of crop choice on global nutrient needs

    2014-01-01

    Solutions to meet growing food requirements in a world of limited suitable land and degrading environment focus mainly on increasing crop yields, particularly in poorly performing regions, and reducing animal product consumption. Increasing yields could alleviate land requirements, but imposing higher soil nutrient withdrawals and in most cases larger fertilizer inputs. Lowering animal product consumption favors a more efficient use of land as well as soil and fertilizer nutrients; yet actual saving may largely depend on which crops and how much fertilizer are used to feed livestock versus people. We show, with a global analysis, how the choice of cultivated plant species used to feed people and livestock influences global food production as well as soil nutrient withdrawals and fertilizer additions. The 3 to 15-fold differences in soil nutrient withdrawals per unit of energy or protein produced that we report across major crops explain how composition shifts over the last 20 years have reduced N, maintained P and increased K harvest withdrawals from soils while contributing to increasing dietary energy, protein and, particularly, vegetable fat outputs. Being highly variable across crops, global fertilization rates do not relate to actual soil nutrient withdrawals, but to monetary values of harvested products. Future changes in crop composition could contribute to achieve more sustainable food systems, optimizing land and fertilizer use. (letter)

    Hydropower is a well established electricity system on the global scene. Global electricity needs by far exceed the amount of electricity that hydrosystems can provide to meet global electricity needs. Much of the world's hydropower remains to be brought into production. Improved technology, better calibrated environmental parameters for large projects have become the norm in the past 15 years. How and why does hydropower retain a prominent role in electricity production? How and why does hydropower find social acceptance in diverse social systems? How does hydropower project planning address issues beyond electricity generation? How does the systems approach to hydropower installations further analysis of comparative energy sources powering electricity systems? Attention to the environmental impact of hydropower facilities forms an integral part of systems analysis. Similarly, the technical, political and economic variables call for balanced analysis to identify the viability status of hydro projects. Economic competition among energy systems requires in context assessments as these shape decision making in planning of hydropower systems. Moreover, technological change has to be given a time frame during which the sector advances in productivity and share in expanding electricity generation. The low production costs per kWh assure hydropower at this juncture, 2009, a very viable future. (author)

    Cancer incidence and mortality rates show great variations across nations and between population groups. These variations are largely explained by differences in age distribution, diet and lifestyle, access to health care, cultural barriers and exposure to carcinogens and pathogens. Cancers caused by infections are significantly more common in developing than developed countries, and they overproportionally affect immigrant populations in the USA and other countries. The global pattern of cancer is not stagnant. Instead, it is dynamic because of fluctuations in the age distribution of populations, improvements in cancer prevention and early detection in affluent countries and rapid changes in diet and lifestyle in parts of the world. For example, increased smoking rates have caused tobacco-induced cancers to rise in various Asian countries, whereas reduced smoking rates have caused these cancers to plateau or even begin to decline in Western Europe and North America. Some population groups experience a disproportionally high cancer burden. In the USA and the Caribbean, cancer incidence and mortality rates are excessively high in populations of African ancestry when compared with other population groups. The causes of this disparity are multifaceted and may include tumor biological and genetic factors and their interaction with the environment. In this review, we will discuss the magnitude and causes of global cancer health disparities and will, with a focus on African-Americans and selected cancer sites, evaluate the evidence that genetic and tumor biological factors contribute to existing cancer incidence and outcome differences among population groups in the USA.

  8. Trajectory Planning of Mobile robot in Unstructured Environment for Multiple Objects

    2012-01-01

    Full Text Available In this paper we have presented a novel technique for the navigation and path formulation of wheeled mobile robot. In a given environment having obstacles, a path is generated from the given initial and final position of the robot. Based on the global knowledge of the environment a global path is formulated initially. This global path considers all the known obstacles in the environment and must avoid collision with these obstacles, i.e. the formulated path must be safe (collision free. For global path formulation strategic schemes have been employed using the a priori knowledge of the environment. The global path is fed to the robot. When unknown obstacles come in the path of the robot, it must deviate from the given global path and should generate a local path to avoid collision with the new unknown obstacle. By using sensors data the reactive schemes have been implemented for local path formulation. For local path formulation the path has been subdivided into intermediate steps known as sub goals. In the existing approaches known and unknown objects are considered separately. But in some of the practical applications known and unknown objects need to be considered simultaneously. This paper considers the problem of robot motion formulation in an environment having already known obstacles and unknown new moving objects. A Novel algorithm has been developed which incorporates local path planner, optimization and navigation modules. As unknown objects can appear in the environment randomly therefore uncertainty in the environment has been considered.

    The total environment includes 5 closely-linking circles, in which biosphere and lithosphere are the active core. As global population increases and urbanization process accelerates, arable land is gradually decreasing under global climate change and the pressure of various types of environmental pollution. This case is especially for China. Land is the most important resources for human beings' survival. How to increase and manage arable land is the key for sustainable agriculture development. China has extensive marshy land that can be reclamated for the better potential land resources under the pre- condition of protecting the environment, which will be a good way for enlarging globally and managing arable land. Related studies have been conducted in China for the past 30years and now many results with obvious practical efficiency have been obtained. For summarizing these results, salt-soil will be the main target and related contents such as nutrient transport, use types, biodiversity and interactions with plants from molecular biology to ecology will be covered, in which the interactions among biosphere, lithosphere, atmosphere and anthroposphere will be focused on.

    2016-01-01

    Full Text Available Globalization is an ongoing phenomenon trying to redefine the economic, social, cultural and political dynamics of contemporary societies. The communication among countries and not only them, has been increased expanding political ties, making possible greater economic integration and wider cultural relations combined with augmented global wealth across the world. But, the process of globalization is in wider terms considered a beneficial one, but also viewed by some countries as a menace to national sovereignty and national culture. This paper tries to explain the obstacles to the process of globalization and its attendant benefits. Although globalization has arisen as a result of a more stable world, the factors that had contributed to its rise also help the factions interested to bring destabilization. In an academic approach in this article, between the research and comparative methods, I have been trying to get the maxims between economy, politics and diplomacy in their efforts of affecting the global era.

  12. The world bank and the environment. Progress report

    1991-01-01

    The second annual report describes specific environmental strategies and environmental lending in the Bank's four operational regions: Africa; Asia; Europe, Middle East, and North Africa; and Latin America and the Caribbean. It details the Bank's progress in eight environmental categories: energy and the environment, pollution, urban environment, water resources management, forest and land management, social and cultural, environmental economics, and the global environment. One chapter is devoted exclusively to tropical forests, studying ways in which the Bank is dealing with deforestation as a part of the constant review of its forest policies. Suggestions are made for decreasing the degradation of tropical forests while meeting demands for forest products. This chapter reflects a shift in Bank emphasis from commercial ventures to conservation measures. The publication reports on other initiatives by the Bank during fiscal 1991, including the launching of the Global Environment Facility (GEF)--a pilot program to oversee reduction of global warming, preservation of biological diversity, protection of international waters, and prevention of ozone depletion

  13. Evolution of the concentration PDF in random environments modeled by global random walk

    The evolution of the probability density function (PDF) of concentrations of chemical species transported in random environments is often modeled by ensembles of notional particles. The particles move in physical space along stochastic-Lagrangian trajectories governed by Ito equations, with drift coefficients given by the local values of the resolved velocity field and diffusion coefficients obtained by stochastic or space-filtering upscaling procedures. A general model for the sub-grid mixing also can be formulated as a system of Ito equations solving for trajectories in the composition space. The PDF is finally estimated by the number of particles in space-concentration control volumes. In spite of their efficiency, Lagrangian approaches suffer from two severe limitations. Since the particle trajectories are constructed sequentially, the demanded computing resources increase linearly with the number of particles. Moreover, the need to gather particles at the center of computational cells to perform the mixing step and to estimate statistical parameters, as well as the interpolation of various terms to particle positions, inevitably produce numerical diffusion in either particle-mesh or grid-free particle methods. To overcome these limitations, we introduce a global random walk method to solve the system of Ito equations in physical and composition spaces, which models the evolution of the random concentration's PDF. The algorithm consists of a superposition on a regular lattice of many weak Euler schemes for the set of Ito equations. Since all particles starting from a site of the space-concentration lattice are spread in a single numerical procedure, one obtains PDF estimates at the lattice sites at computational costs comparable with those for solving the system of Ito equations associated to a single particle. The new method avoids the limitations concerning the number of particles in Lagrangian approaches, completely removes the numerical diffusion, and

  14. Global Increases in Individualism.

    2017-09-01

    Individualism appears to have increased over the past several decades, yet most research documenting this shift has been limited to the study of a handful of highly developed countries. Is the world becoming more individualist as a whole? If so, why? To answer these questions, we examined 51 years of data on individualist practices and values across 78 countries. Our findings suggest that individualism is indeed rising in most of the societies we tested. Despite dramatic shifts toward greater individualism around the world, however, cultural differences remain sizable. Moreover, cultural differences are primarily linked to changes in socioeconomic development, and to a lesser extent to shifts in pathogen prevalence and disaster frequency.

  15. The emergence of the BRICS – implications for global governance

    Directory of Open Access Journals (Sweden)

    Sotiris Petropoulos

    2013-05-01

    Full Text Available The global financial crisis of 2008, with its detrimental effects on the global economy, was the starting point of a transformation of the global governance landscape. This fluid political and economic global environment seems to be leading to the enhancement of the position of regional powers, especially within the developing world. Hence, the importance of Brazil, Russia, India, China, and, to some extent, South Africa, within the global governance structure has increased. This rise of importance is derived from the enhancement of the economic capabilities of these powers and the fact that economic interdependence has rendered the world more sensitive to the economic policies of these nations. What is even more significant is the fact that these emerging powers have initiated a process of conducting regular meetings for the purpose of discussing and coordinating their actions related to global issues. The BRIC(S meetings seem to be acting as a power multiplier, leading to enhanced pressure on developed countries to accept some proposals from the BRIC(S countries. This development enhances the effectiveness of global governance structures while also legitimizing the notion of a new global governance structure. It is yet to be shown, however, whether the new rising powers will eventually challenge existing global governance structures or be fully integrated into them.

    Cardiovascular disease (CVD), a global epidemic, is responsible for about 30% of all deaths worldwide. While mortality rates from CVD have been mostly declining in the advanced industrialized nations, CVD risk factors, including hypertension, obesity, and diabetes, have been on the increase everywhere. Researchers investigating the social causes of CVD have produced a robust body of evidence documenting the relationships between the work environment and CVD, including through the mechanisms of psychosocial work stressors. We review the empirical evidence linking work, psychosocial stressors, and CVD. These work stressors can produce chronic biologic arousal and promote unhealthy behaviors and thus, increased CVD risk. We offer a theoretical model that illustrates how economic globalization influences the labor market and work organization in high-income countries, which, in turn, exacerbates job characteristics, such as demands, low job control, effort-reward imbalance, job insecurity, and long work hours. There is also a growing interest in "upstream" factors among work stress researchers, including precarious employment, downsizing/restructuring, privatization, and lean production. We conclude with suggestions for future epidemiologic research on the role of work in the development of CVD, as well as policy recommendations for prevention of work-related CVD. © The Author(s) 2016.

    The purpose of this study was to examine associations among the nursing work environment, nurse job satisfaction, and intent to stay for nurses who practice in hospitals in Jordan. A quantitative descriptive cross-sectional survey design was used. Data were collected through survey questionnaires distributed to 650 registered nurses (RNs) who worked in three hospitals in Jordan. The self-report questionnaire consisted of three instruments and demographic questions. The instruments were the Practice Environment Scale of the Nursing Work Index (PES-NWI), the McCain Intent to Stay scale, and Quinn and Shepard's (1974) Global Job Satisfaction survey. Descriptive statistics were calculated for discrete measures of demographic characteristics of the study participants. Multivariate linear regression models were used to explore relationships among the nursing work environment, job satisfaction, and intent to stay, adjusting for unit type. There was a positive association between nurses' job satisfaction and the nursing work environment (t = 6.42, p job satisfaction increased by 1.3 points, controlling for other factors. Overall, nurses employed in public hospitals were more satisfied than those working in teaching hospitals. The nursing work environment was positively associated with nurses' intent to stay (t = 4.83, p job satisfaction. More attention should be paid to create positive work environments to increase job satisfaction for nurses and increase their intent to stay. Hospital and nurse managers and healthcare policymakers urgently need to create satisfactory work environments supporting nursing practice in order to increase nurses' job satisfaction and intent to stay. © 2016 Sigma Theta Tau International.

    A survey was conducted of bio-chemical complex harmonized with the global environment for the purpose of constructing the material production process harmonized with the environment by the process fusion between biological conversion and chemical reaction. Palm oil was taken up as renewable raw material plant resource. The process utilizing bio-chemical reaction advances at normal temperature and pressure and is high in reaction specificity and selectivity. This is a recycling, circulation and environmental harmony type production technology which brings high yield, energy conservation, resource conservation, and low environmental loads. Waste water treatment and production of useful substances from sludge were thought as elementary technology. A possibility was studied of enzyme production by culturing solid waste, and the enzyme was applied to the hydrolysis process. The paper indicated trace components in the palm oil and the extraction method and proposed the production process of new derivatives for adding value to hydrolysate. A study was also made of the overall process flow which integrated these new processes and the material balance. The comprehensive evaluation of this new process was made from the aspect of the product structure, the market, construction cost, economical efficiency, and the environment. 133 refs., 65 figs., 56 tabs.

    Full Text Available Character and dynamics of relationships in international politics, in which the stronger return to real politics content in the functioning of the foreign policy of the great powers, unequivocally affirms that globalization does not work to its declining power that is less credible design concept of modern world society. The global financial collapse that hit the world in 2008 is a convincing indication that most of the globalization is discredited. The belief in one humanity is becoming a less desirable concept. At the same time, with the increase in global issues that require solving, there are numerous human activities that involve unique or international regulation. The world is increasingly one homeostatic system of interdependent parts of a continent where many aspects of the borders between countries are difficult or even impossible to sustain. Hence the importance of global factors, some of which will fully depend on the articulation of individual and community life of people in the future, stressing the importance of the issue of joint management to ensure global peace and security and promote the prosperity around the world in a universally acceptable and effective way. Therefore, the demonstrated substantial shortcomings of global governance of the world, although they discourage belief in humanity, did not reduce the objective need for global access to many amenities of modern human existence. Many aspects of security, ranging from the security of the individual to the energy and environmental security in modern conditions are not conceivable without international access. However, global security management has been associated with numerous limitations and challenges.

  3. Effect of Global Warming and Increased Freshwater Flux on Northern Hemispheric Cooling

    Girihagama, L. N.; Nof, D.

    2016-02-01

    We wish to answer the, fairly complicated, question of whether global warming and an increased freshwater flux can cause Northern Hemispheric warming or cooling. Starting from the assumption that the ocean is the primary source of variability in the Northern hemispheric ocean-atmosphere coupled system, we employed a simple non-linear one-dimensional coupled ocean-atmosphere model. The simplicity of the model allows us to analytically predict the evolution of many dynamical variables of interest such as, the strength of the Atlantic Meridional overturning circulation (AMOC), temperatures of the ocean and atmosphere, mass transports, salinity, and ocean-atmosphere heat fluxes. The model results show that a reduced AMOC transport due to an increased freshwater flux causes cooling in both the atmosphere and ocean in the North Atlantic (NA) deep-water formation region. Cooling in both the ocean and atmosphere can cause reduction of the ocean-atmosphere temperature difference, which in turn reduces heat fluxes in both the ocean and atmosphere. For present day climate parameters, the calculated critical freshwater flux needed to arrest AMOC is 0.08 Sv. For a constant atmospheric zonal flow, there is minimal reduction in the AMOC strength, as well as minimal warming of the ocean and atmosphere. This model provides a conceptual framework for a dynamically sound response of the ocean and atmosphere to AMOC variability as a function of increased freshwater flux. The results are qualitatively consistent with numerous realistic coupled numerical models of varying complexity.

    Highlights: • Integrated assessment model perform a series of scenarios of technology advances. • Explore the potential roles of wind energy technology advance in global energy. • Technology advance impacts on energy consumption and global low carbon market. • Technology advance influences on global energy security and stability. - Abstract: To avoid additional global warming and environmental damage, energy systems need to rely on the use of low carbon technologies like wind energy. However, supply uncertainties, production costs, and energy security are the main factors considered by the global economies when reshaping their energy systems. Here, we explore the potential roles of wind energy technology advancement in future global electricity generations, costs, and energy security. We use an integrated assessment model performing a series of technology advancement scenarios. The results show that double of the capital cost reduction causes 40% of generation increase and 10% of cost ​decrease on average in the long-term global wind electricity market. Today’s technology advancement could bring us the benefit of increasing electricity production in the future 40–50 years, and decreasing electricity cost in the future 90–100 years. The technology advancement of wind energy can help to keep global energy security and stability. An aggressive development and deployment of wind energy could in the long-term avoid 1/3 of gas and 1/28 of coal burned, and keep 1/2 biomass and 1/20 nuclear fuel saved from the global electricity system. The key is that wind resources are free and carbon-free. The results of this study are useful in broad coverage ranges from innovative technologies and systems of renewable energy to the economic industrial and domestic use of energy with no or minor impact on the environment.

    Full Text Available Oceania’s political institutions as well as the Pacific Island Countries international activities are changing. Especially Fiji’s suspension from the Pacific Islands Forum created impediments towards greater regional cooperation within this most eminent regional organization, while sub-regionalism and alternative ways of collaboration were strengthened. At the same time Oceania is receiving renewed global attention. The Pacific Island Countries become increasingly active and visible in international diplomacy. Headed by Fiji they challenge traditional alliances and perceptions and start to take greater responsibility in international organizations such as the United Nations.

    The concept of usability has become an increasingly important consideration in the design of all kinds of technology. As more products are aimed at global markets and developed through internationally distributed teams, usability design needs to be addressed in global terms. Interest in usability as a design issue and specialist area of research and education has developed steadily in North America and Europe since the 1980's. However, it is only over the last ten years that it has emerged as a global concern. Global Usability provides an introduction to the important issues in globalizing des

  9. Progress and challenges to the global waste management system.

    Singh, Jagdeep; Laurenti, Rafael; Sinha, Rajib; Frostell, Björn

    2014-09-01

    Rapid economic growth, urbanization and increasing population have caused (materially intensive) resource consumption to increase, and consequently the release of large amounts of waste to the environment. From a global perspective, current waste and resource management lacks a holistic approach covering the whole chain of product design, raw material extraction, production, consumption, recycling and waste management. In this article, progress and different sustainability challenges facing the global waste management system are presented and discussed. The study leads to the conclusion that the current, rather isolated efforts, in different systems for waste management, waste reduction and resource management are indeed not sufficient in a long term sustainability perspective. In the future, to manage resources and wastes sustainably, waste management requires a more systems-oriented approach that addresses the root causes for the problems. A specific issue to address is the development of improved feedback information (statistics) on how waste generation is linked to consumption. © The Author(s) 2014.

    2011-03-01

    Full Text Available The purpose of this paper is to discuss globalization’s impacts on the world’s financial characteristics today. The findings inform that globalization promotes entrepreneurship because through globalization, financial markets have grown to be more efficient and flexible which can be seen through lower transaction costs, less binding financial regulations than before, less governments’ intervention within private sector and national economy structures, increasing number of market participants which leads to more access to information. Thus, globalization does create a better environment for entrepreneurs in achieving their competitive advantages and further to sustain them. This research was done by collecting data from papers, journals, modules, and internet databases. The data was analyzed and then concluded. Having applied the analytical process, it can be concluded that globalization does promotes entrepreneurship because it enables entrepreneurs to gain greater benefits at a certain degree of freedom than before in order to achieve and maintain their competitive advantages.

    1994-04-15

    This paper considers which way the global civil engineering should go in the future. Civil engineering has now a paradigm with a new dimension debuted as the global environmental problems are taken up specifically. Achieving the target of civil engineering requires a critical review that how the cost effect and efficiency discussions in only the dimensions of the conventional technologies and economies can be incorporated into the dimensions and measures of new fields to create the new horizons. Conceiving the relationship between civil engineered structures and environmental climate encounters the indispensable judgment criterion on how such social scientific conditions as weather, culture, religion, economy, and politics are combined to reach a judgment. The global civil engineering is desired to have the ideas and directional role to work on the ultimate assignment of environment and development called a global environmental problem analytically, comprehensively, innovatively and creatively as the civil engineering science, rather than as a mere existence of one area of the advanced civil engineering science. 5 refs., 1 tab.

    Lung infections with Mycobacterium abscessus, a species of multidrug resistant nontuberculous mycobacteria, are emerging as an important global threat to individuals with cystic fibrosis (CF) where they accelerate inflammatory lung damage leading to increased morbidity and mortality. Previously, M. abscessus was thought to be independently acquired by susceptible individuals from the environment. However, using whole genome analysis of a global collection of clinical isolates, we show that the majority of M. abscessus infections are acquired through transmission, potentially via fomites and aerosols, of recently emerged dominant circulating clones that have spread globally. We demonstrate that these clones are associated with worse clinical outcomes, show increased virulence in cell-based and mouse infection models, and thus represent an urgent international infection challenge.

  17. What is Driving Global Imbalances? The Global Savings Glut Hypothesis Reexamined

    Directory of Open Access Journals (Sweden)

    Jai-Won Ryou

    2009-12-01

    Full Text Available In the middle of the global financial crisis, global imbalances seem to have been resolved to some extent, but it remains to be seen whether these imbalances will emerge again along with economic recovery. In order to cope with this global issue, we need to clarify what caused global imbalances in the first place. This paper aims to evaluate the relative importance of the "global savings glut" to the U.S. external imbalances. Drawing on the portfolio balance model, we analyze how the process of interaction between the U.S. current account deficit, capital inflows, and the U.S. dollar exchange rate is linked to domestic and external factors. Our empirical analysis shows that the U.S. current account deficit maintained since the early 1990s is mainly driven by the domestic factors, such as a decrease in the U.S. national savings and an increase in money supply growth. The size of the negative effect of a "global savings glut" measured by an increase in the East Asian countries' national savings (i.e. China, Japan and Korea on the U.S. current account seems to be exaggerated. Meanwhile, current account does not appear to be sensitive to changes in the exchange rate. This finding implies that the rectification of global imbalances is hardly possible to achieve by means of depreciating the U.S. dollar alone while leaving the structural factors unchanged. In order to achieve global rebalancing, the U.S. should increase its savings rate, reduce fiscal deficit, and tighten its money supply. While an increase in the domestic demand in the surplus countries such as China and Japan may be helpful in rectifying global imbalances, it appears to be insufficient per se.

  18. WHAT FIRMS ARE REWARDED AFTER GLOBAL FINANCIAL CRISIS? THE ROLE OF INNOVATION AND GLOBALIZATION STRATEGIES IN RECOVERY

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available The aim of the research is to conduct an empirical investigation and reveal what types of globalization and innovation strategies in turbulent and unfavorable regional institutional environment are most likely to be associated with different trajectories of Russian manufacturing firms’ performance in 2007- 2012. We employ the results of empirical survey of 1000 medium and large enterprises in manufacturing (2009 linked to financial data from Amadeus database and the data on the regional institutional environment. We test that (1 introduction of innovations before the crisis ceteris paribus helped the firms to successfully pass the crisis and recover. We expect that (2 companies that became globalized before the crisis (via importing of intermediate and capital goods; exporting; FDI; establishment of partner linkages with foreign firms ceteris paribus are more likely to successfully pass the crisis and grow. And (3 propose the positive effect of synergy of innovation efforts and globalization strategy of the firm. We expect that the abovementioned factors are complimentary and reinforce the ability of the firm to recover after crisis shock. We found strong support for the hypothesis that firms financing introduction of new products before the crisis and simultaneously managed to promote and sell them on the global market were rewarded by quick return to the growing path after global crisis. Other strategies, i.e. solely innovations without exporting play insignificant role while exporting without attempts to introduce new products contribute even negatively to post-crisis recover. Institutional environment also matters: in the regions with less level of corruption firms were more likely to grow after the crisis.

    2010-05-01

    Full Text Available Today’s knowledge-based, global commerce requires continuous investment in human capital through postsecondary education for countries to be fiercely competitive. Countries, such as China and India, are experiencing growth in the number of people participating in postsecondary education; the United States has fallen behind. While America needs to focus on increasing college access and degree completion among underrepresented ethnic minorities, particularly in Science, Technology, Engineering, and Mathematics (STEM, educators and policymakers assert that this is particularly important for African American males. Increasing matriculation and graduation rates for African Americans is not only a matter of equity, but in the context of STEM, it has major implications for the competitiveness of the United States in the global economy. This article identifies strategies that educators and policymakers can employ to promote the participation of African American males in college in general, particularly in STEM.

    The purpose of this paper is to try and demonstrate the role that the use of Wood as a Fuel can play in our environment. The term ''Wood Fuel'', for the purposes of these proceedings, refers to the use of wood obtained from the forest or the farm. It does not refer to waste wood from for example buildings. The role of wood fuel in the environment can be assessed at many different levels. In this paper three different scales of ''Environment'' and the role of wood fuel in each, will be considered. These three scales are namely the global environment, the local environment, and the National (community) environment. (Author)

    2017-12-01

    More and more reservoirs are being build or planned in order to help meet the increasing water demand all over the world. However, is building new reservoirs always helpful to water supply? To address this question, the river routing module of Global Change Assessment Model (GCAM) has been extended with a simple yet physical-based reservoir scheme accounting for irrigation, flood control and hydropower operations at each individual reservoir. The new GCAM river routing model has been applied over the global domain with the runoff inputs from the Variable Infiltration Capacity Model. The simulated streamflow is validated at 150 global river basins where the observed streamflow data are available. The model performance has been significantly improved at 77 basins and worsened at 35 basins. To facilitate the analysis of additional reservoir storage impacts at the basin level, a lumped version of GCAM reservoir model has been developed, representing a single lumped reservoir at each river basin which has the regulation capacity of all reservoir combined. A Sequent Peak Analysis is used to estimate how much additional reservoir storage is required to satisfy the current water demand. For basins with water deficit, the water supply reliability can be improved with additional storage. However, there is a threshold storage value at each basin beyond which the reliability stops increasing, suggesting that building new reservoirs will not help better relieve the water stress. Findings in the research can be helpful to the future planning and management of new reservoirs.

    The influence of globalization on psychological functioning is examined. First, descriptions of how globalization is occurring in various world regions are presented. Then the psychological consequences of globalization are described, with a focus on identity issues. Specifically, it is argued that most people worldwide now develop a bicultural identity that combines their local identity with an identity linked to the global culture; that identity confusion may be increasing among young people in non-Western cultures as a result of globalization; that some people join self-selected cultures to maintain an identity that is separate from the global culture; and that a period of emerging adulthood increasingly extends identity explorations beyond adolescence, through the mid- to late twenties.

    Full Text Available The field of Global Health brings together a vastly diverse array of actors working to address pressing health issues worldwide with unprecedented financial and technological resources and informed by various agendas. While Global Health initiatives are booming and displacing earlier framings of the field (such as tropical medicine or international health, critical analyses of the social, political, and economic processes associated with this expanding field — an “open source anarchy” on the ground — are still few and far between. In this essay, we contend that, among the powerful players of Global Health, the supposed beneficiaries of interventions are generally lost from view and appear as having little to say or nothing to contribute. We make the case for a more comprehensive and people-centered approach and demonstrate the crucial role of ethnography as an empirical lantern in Global Health. By shifting the emphasis from diseases to people and environments, and from trickle-down access to equality, we have the opportunity to set a humane agenda that both realistically confronts challenges and expands our vision of the future of global communities.

  8. Preparing for climate change impacts in Norway's built environment

    International Nuclear Information System (INIS)

    Robert Lisoe, K.; Aandahl, G.; Eriksen, S.; Alfsen, K.

    2003-01-01

    This paper provides an overview of the Norwegian climate policy and of the practical implications of preparing Norway for climate change, with special emphasis on the challenges confronting the built environment. Although the Norwegian government has been relatively proactive in instituting measures aimed at halting global climate change, less attention has been paid to the challenge of adapting to climate change. The global climate system is likely to undergo changes, regardless of the implementation of abatement policies under the Kyoto Protocol or other regimes. The full range of impacts resulting from these changes is still uncertain; however, it is becoming increasingly clear that adaptation to climate change is necessary and inevitable within several sectors. The potential impacts of climate change in the built environment are now being addressed. Both the functionality of the existing built environment and the design of future buildings are likely to be altered by climate change impacts, and the expected implications of these new conditions are now investigated. However, measures aimed at adjustments within individual sectors, such as altering the criteria and codes of practice for the design and construction of buildings, constitute only a partial adaptation to climate change. In order to adapt effectively, larger societal and intersectoral adjustments are necessary. (author)

    Full Text Available In response to radically increasing competition, many manufacturers who produce time-sensitive products have expanded their production plants to worldwide sites. Given this environment, how to aggregate customer orders from around the globe and assign them quickly to the most appropriate plants is currently a crucial issue. This study proposes an effective method to solve the order assignment problem of companies with multiple plants distributed worldwide. A multiobjective genetic algorithm (MOGA is used to find solutions. To validate the effectiveness of the proposed approach, this study employs some real data, provided by a famous garment company in Taiwan, as a base to perform some experiments. In addition, the influences of orders with a wide range of quantities demanded are discussed. The results show that feasible solutions can be obtained effectively and efficiently. Moreover, if managers aim at lower total costs, they can divide a big customer order into more small manufacturing ones.

    Tsai, Wen-Tien

    2017-09-21

    Among the halogenated hydrocarbons, chloromethanes (i.e., methyl chloride, CH₃Cl; methylene chloride, CH₂Cl₂; chloroform, CHCl₃; and carbon tetrachloride, CCl₄) play a vital role due to their extensive uses as solvents and chemical intermediates. This article aims to review their main chemical/physical properties and commercial/industrial uses, as well as the environment and health hazards posed by them and their toxic decomposition products. The environmental properties (including atmospheric lifetime, radiative efficiency, ozone depletion potential, global warming potential, photochemical ozone creation potential, and surface mixing ratio) of these chlorinated methanes are also reviewed. In addition, this paper further discusses their atmospheric fates and human health implications because they are apt to reside in the lower atmosphere when released into the environment. According to the atmospheric degradation mechanism, their toxic degradation products in the troposphere include hydrogen chloride (HCl), carbon monoxide (CO), chlorine (Cl₂), formyl chloride (HCOCl), carbonyl chloride (COCl₂), and hydrogen peroxide (H₂O₂). Among them, COCl₂ (also called phosgene) is a powerful irritating gas, which is easily hydrolyzed or thermally decomposed to form hydrogen chloride.

    2001-01-01

    Energy transit plays a significant role in the energy development and globalization of the energy economy due to the dependence of the countries of large energy consumers on the energy import and the increase of export from the regions which do not have a direct connection with these consumers. In such circumstances huge amounts of energy cross several borders on their way from energy producers to energy consumers ''facing'' the risks of different political systems as well as different economic, legislative and social conditions together with environment protection conditions. With the purpose of reducing such and other risks and increasing the security level of consumer supply as well as the economic results in the energy sector, huge efforts are being made in creating market, non-discriminatory and transparent transit conditions through international treaties, agreements, conventions, protocols and similar. Owing to its geographical position, especially on the Mediterranean, the Republic of Croatia is an interesting transit country, but until now it profited only partially from this advantage. By constructing new gas pipelines and new connections of the existing oil pipeline with the European network both for the needs of local supply and transit, and according to the adopted international obligations on the conditions of the access to available capacities, construction of new capacities, market pricing, environment protection and other, oil and gas transit through this Croatia of Ours will be increased and further integration of oil and gas economy into the globalization processes will be speeded up.(author)

    Through visits to US universities and research institutes, investigation was made on the trend of global environment-related research and possibility of their exchanging the result of research with the RITE (Research Institute of Innovative Technology for the Earth). To investigate the process technology to utilize microbes harmoniously with the environment, the visit was paid to Cornell University, Battelle Memorial Institute and Risk Reduction Engineering Laboratory, where the investigation was made on the environmental bioremediation with microbial functions and clean process production without by-producing substances to load the environment. To investigate the technical measures against the global warming, the visit was paid to Brookhaven National Laboratory, Massachusetts Institute of Technology, California University, Hawaii University and Pacific International Center for High Technology Research, where the investigation was made, through discussion and exchange of research information and opinion with researchers and engineers, on the possibility of their exchanging the result of research with the RITE. Judging from the investigation of this time, the research which is mutually complementary between Japan and USA is easy to promote, because their respective advanced fields do not overlap with each other. 88 refs., 11 figs., 6 tabs.

    In anticipation of UN Conference on Environment and Development scheduled for June in Brazil, the Japan Broadcasting Corporation (NHK) recently televised a hard-hitting documentary focusing on the impact of rapid population growth on resources and the environment. Entitled "Population Explosion and the Looming Crisis: Can Humankind Determine a Better Future?" the documentary aired on January 5, featuring interviews with experts from the population field such as Dr. Nafis Sadik of the UNFPA and Dr. Paul Ehrlich of Stanford University. The program, made with the cooperation of UNFPA and JOICFP, compared the current global demograhic and environmental situation with the one expected to exist in 2025, when the world population is expected to reach 10 billion. The documentary depicted a future fraught with food shortages, depleted energe resources, refugees, and a devastated environment. In order to illustrate the effect of population growth in developing countries, the documentary featured reports from countries in Asia and Africa. And to show the heavy burden that industrialized countries place on the global environment, the documentary examined Japan's own pattern of consumption and waste. As the UNFPA's Sadik pointed out, the luxurious lifestyle of developed countries comes at the expense of the developing world. Stressing that everyone in the world should be able to enjoy a reasonable standard of living. Sadik called for "sustainable patterns of development," which can be achieved through the following: improved technology, reduced consumption patterns, and changed lifestyles. A critical element in changing lifestyles includes reducing global fertility to 3.2 children/woman by the year 2000. Otherwise, a world population will not double but triple by the year 2025.

    A dynamic linear compartment model of the global iodine cycle has been developed for the purpose of estimating long-term doses and dose commitments to the world population from releases of 129 I to the environment. The environmental compartments assumed in the model comprise the atmosphere, hydrosphere, lithosphere, and terrestrial biosphere. The global transport of iodine is described by means of time-invariant fractional transfer rates between the environmental compartments. The fractional transfer rates for 129 I are determined primarily from available data on compartment inventories and fluxes for naturally occurring stable iodine and from data on the global hydrologic cycle. The dose to the world population is estimated from the calculated compartment inventories of 129 I, the known compartment inventories of stable iodine, a pathway analysis of the intake of iodine by a reference individual, dose conversion factors for inhalation and ingestion, and an estimate of the world population. For an assumed constant population of 12.21 billion beyond the year 2075, the estimated population dose commitment is 2 x 10 5 man-rem/Ci. The sensitivity of the calculated doses to variations in some of the parameters in the model for the global iodine cycle is investigated. A computer code written to calculate global compartment inventories and dose rates and population doses is described and documented

    Global warming events have coincided with turnover of plant species at intervals in Earth history. As mean global temperatures rise, the number, frequency and duration of heat-waves will increase. Ginkgo biloba was grown under controlled climatic conditions at two different day/night temperature regimes (25/20 °C and 35/30 °C) to investigate the impact of heat stress. Photosynthetic CO 2 -uptake and electron transport were reduced at the higher temperature, while rates of respiration were greater; suggesting that the carbon balance of the leaves was adversely affected. Stomatal conductance and the potential for evaporative cooling of the leaves was reduced at the higher temperature. Furthermore, the capacity of the leaves to dissipate excess energy was also reduced at 35/30 °C, indicating that photo-protective mechanisms were no longer functioning effectively. Leaf economics were adversely affected by heat stress, exhibiting an increase in leaf mass per area and leaf construction costs. This may be consistent with the selective pressures experienced by fossil Ginkgoales during intervals of global warming such as the Triassic - Jurassic boundary or Early Eocene Climatic Optimum. The physiological and morphological responses of the G. biloba leaves were closely interrelated; these relationships may be used to infer the leaf economics and photosynthetic/stress physiology of fossil plants.

    As liberalisation of global trade and investment accelerates, what happens to the environment? As the world heads for confrontation in Seattle, the questions intensify. Does foreign direct investment mean forsaking environmental protection? Or do multinational corporations export higher standards when they invest abroad? Can a powerful trading nation ban imports of tropical timber produced unsustainably? Should the World Trade Organisation take the views of industry or environmental groups into account when deciding? Must world trade rules be changed to accommodate environmental concerns? This book analyzes key issues in this increasingly controversial arena and includes contributions from Renato Ruggiero, former Director General of the World Trade Organization; The Rt Hon Brian Wilson MP, former UK Minister of Trade; Dr Magda Shahin, Deputy Assistant Minister of Foreign Affairs at the Egyptian Ministry of Foreign Affairs; Pradeep Mehta, Secretary General, Consumer Unity and Trust Society, India; and Dr Michel Potier, Head of the Economics Division at the OECD's Environment Directorate.

    Three themes in global mountain geomorphology have been defined and reinforced over the past decade: (a) new ways of measuring, sensing, and analyzing mountain morphology; (b) a new emphasis on disconnectivity in mountain geomorphology; and (c) the emergence of concerns about the increasing influence of anthropogenic disturbance of the mountain geomorphic environment, especially in intertropical mountains where population densities are higher than in any other mountain region. Anthropogenically induced hydroclimate change increases geomorphic hazards and risks but also provides new opportunities for mountain landscape enhancement. Each theme is considered with respect to the distinctiveness of mountain geomorphology and in relation to important advances in research over the past decade. The traditional reliance on the high energy condition to define mountain geomorphology seems less important than the presence of unique mountain landforms and landscapes and the distinctive ways in which human activity and anthropogenically induced hydroclimate change are transforming mountain landscapes.

    The MOSIX extensions to the Linux Operating System allow the creation of high-performance Linux Farms and an excellent integration of the several CPUs of the Farm, whose computational power can be furtherly increased and made more effective by networking them within the GRID environment. Following this strategy, the authors started to perform computational tests using two independent farms within the GRID environment. In particular, the authors performed a preliminary evaluation of the distributed computing efficiency with a MOSIX Linux farm in the simulation of gravitational waves data analysis from coalescing binaries. To this task, two different techniques were compared: the classical matched filters technique and one of its possible evolutions, based on a global optimisation technique

    Using the spin-wave approximation, we study the geometric phase (GP) of a central spin (signal qubit) coupled to an antiferromagnetic (AF) environment under the application of an external global magnetic field. The external magnetic field affects the GP of the qubit directly and also indirectly through its effect on the AF environment. We find that when the applied magnetic field is increased to the critical magnetic field point, the AF environment undergoes a spin-flop transition, a first-order phase transition, and at the same time the GP of the qubit changes abruptly to zero. This sensitive change of the GP of a signal qubit to the parameter change of a many-body environment near its critical point may serve as another efficient tool or witness to study the many-body phase transition. The influences of the AF environment temperature and crystal anisotropy field on the GP are also investigated.

    Large tsunamis occur infrequently but have the capacity to cause enormous numbers of casualties, damage to the built environment and critical infrastructure, and economic losses. A sound understanding of tsunami hazard is required to underpin management of these risks, and while tsunami hazard assessments are typically conducted at regional or local scales, globally consistent assessments are required to support international disaster risk reduction efforts, and can serve as a reference for local and regional studies. This study presents a global-scale probabilistic tsunami hazard assessment (PTHA), extending previous global-scale assessments based largely on scenario analysis. Only earthquake sources are considered, as they represent about 80% of the recorded damaging tsunami events. Globally extensive estimates of tsunami run-up height are derived at various exceedance rates, and the associated uncertainties are quantified. Epistemic uncertainties in the exceedance rates of large earthquakes often lead to large uncertainties in tsunami run-up. Deviations between modelled tsunami run-up and event observations are quantified, and found to be larger than suggested in previous studies. Accounting for these deviations in PTHA is important, as it leads to a pronounced increase in predicted tsunami run-up for a given exceedance rate.

  9. Chinese Entrepreneurs Go Global

    Full Text Available China may be on the tipping point of explosive global growth. In response to changes in the global economy and an economic slowdown domestically, hundreds of thousands of Chinese SMEs are being encouraged to “go global” by their central and local governments. To a Chinese company, going global requires the expansion of its existing business in other countries or the development of new ventures with partners operating in other countries. Explosive growth in China may be possible, but it will depend on an appropriate strategy for going global. For a country that has firmly established itself as an international manufacturing hub, going global requires a shift in its entrepreneurial capacity, which is the focus of this article. We first assess the current situation in China to understand its current entrepreneurial focus and capacity, as well as the impetus for change. Next, we contrast the Kirznerian and Schumpeterian views of entrepreneurship to illustrate that – to go global – Chinese entrepreneurs must shift from an emphasis on exploiting pricing inefficiencies (i.e., Kirznerian entrepreneurship to an emphasis on innovation (i.e., Schumpeterian entrepreneurship. Finally, we examine unique characteristics of the business environment and culture in China, which are likely to impact the ability of Chinese entrepreneurs to go global.

  10. Plant volatiles in extreme terrestrial and marine environments.

    2014-08-01

    This review summarizes the current understanding on plant and algal volatile organic compound (VOC) production and emission in extreme environments, where temperature, water availability, salinity or other environmental factors pose stress on vegetation. Here, the extreme environments include terrestrial systems, such as arctic tundra, deserts, CO₂ springs and wetlands, and marine systems such as sea ice, tidal rock pools and hypersaline environments, with mangroves and salt marshes at the land-sea interface. The emission potentials at fixed temperature and light level or actual emission rates for phototrophs in extreme environments are frequently higher than for organisms from less stressful environments. For example, plants from the arctic tundra appear to have higher emission potentials for isoprenoids than temperate species, and hypersaline marine habitats contribute to global dimethyl sulphide (DMS) emissions in significant amounts. DMS emissions are more widespread than previously considered, for example, in salt marshes and some desert plants. The reason for widespread VOC, especially isoprenoid, emissions from different extreme environments deserves further attention, as these compounds may have important roles in stress resistance and adaptation to extremes. Climate warming is likely to significantly increase VOC emissions from extreme environments both by direct effects on VOC production and volatility, and indirectly by altering the composition of the vegetation. © 2014 John Wiley & Sons Ltd.

    A tool to assess the built environment, which takes into account issues of disability, accessibility and the need for data comparable across countries and populations, is much needed. The Collaborative Research on Ageing in Europe (COURAGE) in Europe Built Environment Outdoor Checklist (CBE-OUT) helps us to understand when features of the neighbourhood environment have either a positive or negative impact on the accessibility of neighbourhoods for healthy ageing. The CBE-OUT is composed of 128 items that can be recorded when present in the evaluated environment. Audits were performed in households randomly selected from each cluster of the sample for Finland, Poland and Spain, following precise rules defined by experts. Global scores were computed both section by section and in the overall checklist, rescaling the resulting scores from 0 (negative environment) to 100 (positive). The total number of completed CBE-OUT checklists was 2452 (Finland, 245; Poland, 972; and Spain, 1235). Mean global score for our sample is 49.3, suggesting an environment composed both of facilitating and hindering features. Significant differences were observed in the built environment features of the three countries and in particular between Finland and the other two. The assessment of features of built environment is crucial when thinking about ageing and enhanced participation. The COURAGE in Europe project developed this tool to collect information on built environment in an objective evaluation of environmental features and is a recommended methodology for future studies. The CBE-OUT checklist is an objective evaluation of the built environment and is centred on technical measurement of features present in the environment and has its foundations in the concepts of disability and accessibility operating in the International Classification of Functioning, Disability and Health (ICF) model. The CBE-OUT checklist can be analysed using both the total score and the single section score

    Full Text Available In this paper we investigate the different approaches of the globalization phenomenon. Despite the geographical distancesm, the link between people are ever more strong on different ways and plans: from technology between political, economical, cultural world events, and many other aspects. So, the link between globalization and democracy, and its impact on the most important social and economic matters. We also surprise the impact of the internet revolution and its corolar e-commerce, and its consequences, sometimes unpredictible ones. Another annalysed problem is that of the governments trying, and sometimes succeeding to controll the money, products, peole and their ideas that freely move inside the national frontiers, thus going to slower or to stop the progress. Nevertheless, this global interraction between people also create phenomena of insecurity on different ways: terrorism, traffic of arms, drugs, economical aggresions causing the environment, and other inconvenient facts and situations.

    Melluish, Steve

    2014-10-01

    This article outlines the cultural and psychological effects of globalization. It looks at the impact of globalization on identity; ideas of privacy and intimacy; the way we understand and perceive psychological distress; and the development of the profession of psychology around the world. The article takes a critical perspective on globalization, seeing it as aligned with the spread of neoliberal capitalism, a tendency towards cultural homogenization, the imposition of dominant 'global north' ideas and the resultant growing inequalities in health and well-being. However, it also argues that the increased interconnectedness created by globalization allows for greater acknowledgement of our common humanity and for collective efforts to be developed to tackle what are increasingly global problems. This requires the development of more nuanced understandings of cultural differences and of indigenous psychologies.

    The advent of the new millennium has witnessed the embracing of a different perspective on global health aid. New and innovative mechanisms in health-aid financing are leading to new opportunities, focused on greater innovation, risk taking and speed. However, these opportunities might not fully materialize if the traditional approaches of channeling and using funds are followed. To maximize global aid effectiveness and to have a realistic chance of achieving the Millennium Development Goals, the implementation of a holistic approach to the global architecture of health aid will be essential.

    The flux of carbon dioxide from the soil to the atmosphere (soil respiration) is one of the major fluxes in the global carbon cycle. At present, the accumulated field observation data cover a wide range of geographical locations and climate conditions. However, there are still large uncertainties in the magnitude and spatiotemporal variation of global soil respiration. Using a global soil respiration data set, we developed a climate-driven model of soil respiration by modifying and updating Raich's model, and the global spatiotemporal distribution of soil respiration was examined using this model. The model was applied at a spatial resolution of 0.5°and a monthly time step. Soil respiration was divided into the heterotrophic and autotrophic components of respiration using an empirical model. The estimated mean annual global soil respiration was 91 Pg C yr-1 (between 1965 and 2012; Monte Carlo 95 % confidence interval: 87-95 Pg C yr-1) and increased at the rate of 0.09 Pg C yr-2. The contribution of soil respiration from boreal regions to the total increase in global soil respiration was on the same order of magnitude as that of tropical and temperate regions, despite a lower absolute magnitude of soil respiration in boreal regions. The estimated annual global heterotrophic respiration and global autotrophic respiration were 51 and 40 Pg C yr-1, respectively. The global soil respiration responded to the increase in air temperature at the rate of 3.3 Pg C yr-1 °C-1, and Q10 = 1.4. Our study scaled up observed soil respiration values from field measurements to estimate global soil respiration and provide a data-oriented estimate of global soil respiration. The estimates are based on a semi-empirical model parameterized with over one thousand data points. Our analysis indicates that the climate controls on soil respiration may translate into an increasing trend in global soil respiration and our analysis emphasizes the relevance of the soil carbon flux from soil to
