  10. International nuclear institutions and utilities structures for the 21st century

    International Nuclear Information System (INIS)

    The development of international nuclear institutions during the 20th Century has been extraordinary. It has included international government institutions, such as the International Atomic Energy Agency; international scientific organizations, such as the International Committee on Radiological Protection; international operating support organizations, such as the World Association of Nuclear Operators; and international professional society organizations, such as the International Nuclear Societies Council. We should now examine the relevance of the current institutions and how they can be enhanced for the 21st Century. Examples of potential changes include the following. The scope of government's international responsibilities is being significantly expanded by the Convention of Nuclear Safety of Radioactive Waste Management and Spent Fuel. The implementation of these new conventions will require major actions during the next century. The science upon which international standards have been developed is vastly improved and the assessment is changing. Thus, the guidance provided by organizations such as the ICRP will need to be re-evaluated. The World Association of Nuclear Operators has focuses on operating programs but this scope may be too narrow for the future as designs and standards evolve. The nuclear professional societies have contributed a great deal to the exchange of technology throughout the world but this traditional role may need to be revised in order that political decisions match the relevant scientific data. In addition to the changes within these institutions for the next century, the electric utilities that produce nuclear power will be restructured in many countries. The concept of privatization of utilities and their disaggregation from an integrated generation, transmission and distribution company into separate entities is proceeding quickly. The structure of the utility system will be markedly different in a few years from that which we

    @@ Dramatic changes have occurred in the post-Cold War world strategic configuration and international order with their replacements burgeoning. This confronts nations, big powers in particular, with new strategic choices. Indeed unfolding before us is a contention among them for seizing the initiative in the emerging international landscape in the 21st century.Thus how to correctly assess and respond to these changes for pursuing a reasonable strategy and selecting a right policy option is not only a matter of primary concern for the academic community, but also a major foreign policy task before a rapidly growing China. For this, a symposium on this theme was recently sponsored by the Editorial Department of Contemporary International Relations to solicit from a dozen or so Beijingbased well-known scholars and experts for their views on and policy suggestions for such issues as the current overall strategic picture, global configuration, trends of the international order and the strategic environment facing China. Excerpts of their major views are as follows.

  14. The Large Marine Ecosystem Approach for 21st Century Ocean Health and International Sustainable Development

    Science.gov (United States)

    Honey, K. T.

    2014-12-01

    The global coastal ocean and watersheds are divided into 66 Large Marine Ecosystems (LMEs), which encompass regions from river basins, estuaries, and coasts to the seaward boundaries of continental shelves and margins of major currents. Approximately 80% of global fisheries catch comes from LME waters. Ecosystem goods and services from LMEs contribute an estimated US 18-25 trillion dollars annually to the global economy in market and non-market value. The critical importance of these large-scale systems, however, is threatened by human populations and pressures, including climate change. Fortunately, there is pragmatic reason for optimism. Interdisciplinary frameworks exist, such as the Large Marine Ecosystem (LME) approach for adaptive management that can integrate both nature-centric and human-centric views into ecosystem monitoring, assessment, and adaptive management practices for long-term sustainability. Originally proposed almost 30 years ago, the LME approach rests on five modules are: (i) productivity, (ii) fish and fisheries, (iii) pollution and ecosystem health, (iv) socioeconomics, and (v) governance for iterative adaptive management at a large, international scale of 200,000 km2 or greater. The Global Environment Facility (GEF), World Bank, and United Nations agencies recognize and support the LME approach—as evidenced by over 3.15 billion in financial assistance to date for LME projects. This year of 2014 is an exciting milestone in LME history, after 20 years of the United Nations and GEF organizations adopting LMEs as a unit for ecosystem-based approaches to management. The LME approach, however, is not perfect. Nor is it immutable. Similar to the adaptive management framework it propones, the LME approach itself must adapt to new and emerging 21st Century technologies, science, and realities. The LME approach must further consider socioeconomics and governance. Within the socioeconomics module alone, several trillion-dollar opportunities exist

  15. Developing skills for youth in the 21st century: The role of elite International Baccalaureate Diploma Programme schools in China

    Wright, Ewan; Lee, Moosung

    2014-04-01

    There is a growing body of research suggesting that schools need to respond to changing social and economic dynamics by prioritising "21st-century skills". Proponents of this view, who have been termed "the 21st century skills movement", have called for greater emphasis on cognitive and non-cognitive skills development, alongside the learning of subject content and technical skills. This paper explores the potential of International Baccalaureate Diploma Programme (IBDP) schools to respond to this mandate in China, one of the fastest-growing markets for International Baccalaureate® (IB) schools globally. The authors' research team undertook a multi-site case study of five elite IBDP schools in China. Their findings revealed confidence among interviewees that the IB educational philosophy was conducive to 21st-century skills development, especially through the provision of the three IBDP "Core Requirements", which are Creativity, Action, Service (CAS), Extended Essay (EE) and Theory of Knowledge (TOK). Despite this confidence, concerns remain about the implementation of the IB educational philosophy in the context of IBDP schools in China.

    International Nuclear Information System (INIS)

    objectives of the conference were the following: 1) To review the role of nuclear power and to define the potential benefits (energy security, sustainability and improved environmental protection) that expanding nuclear power offers to meet the increasing energy needs of the world. 2) To facilitate a discussion on the issue of nuclear energy and society involving experts and decision makers. The conference consisted of two major elements. The first element was invited ministerial presentations on the current and future role of nuclear power in the context of national energy strategies, while the second was round table discussions involving renowned international experts to discuss: World energy needs and resources; Environmental challenges of the 21st century; Driving factors for strategies and choices; Governance issues. This conference was held to enable the future of nuclear power to be discussed at the ministerial level. Participation included 465 experts from 69 IAEA Member States and eight international organizations. Presentations of national visions on the future of nuclear power by 25 ministers in person, and seven presentations made on behalf of Ministers, demonstrated the timeliness and importance of the conference. The participation of about 75 press and media representatives and broad media coverage were further indications of the wide interest in the future of nuclear power. In many views presented, and in two round table discussions, the potential significant role of nuclear energy in meeting the energy needs of the planet was recognized, in particular that: 1) Developments in technology and improvements in management resulted in better safety, and that the economics of nuclear power made it increasingly attractive and fully competitive. 2) Nuclear power can contribute in meeting the needs of the Millennium Development Goals and the Johannesburg Plan of Implementation, such as the eradication of poverty and hunger, universal access to plentiful fresh water and

    The Institute of Nuclear Materials Management (INMM) held an International Workshop on 'Containment and Surveillance: Concepts for the 21st Century' on June 6-11, 2010 at the Oak National Laboratory in Oak Ridge, Tennessee. The National Nuclear Security Administration Offices of Non-proliferation Research and Development and Office of Nuclear Safeguards sponsored the event. The workshop focused on determining concepts and needs for 21st century containment and surveillance (C/S) systems that support International Atomic Energy Agency safeguards and future arms control agreements. Panel discussions from subject matter experts and international practitioners provided the daily topical theme of the following areas of C/S: authentication, tagging, sealing, containment verification, and surveillance systems. Each panel discussion was followed with a question and answer session with the audience and an afternoon breakout session. The facilitated breakout sessions were used to compile and determine future needs. Individuals attending the workshop included C/S experts and practitioners; IAEA and arms control inspectors, technology providers, vendors, students and individuals with an interest in or desire to learn about future C/S system needs. The primary goal for the workshop was to produce a document that details the future research and development needs for C/S systems that support nuclear safeguards and arms control missions. This paper will present a compilation of the information obtained from breakout sessions at the workshop. (author)

    Much has been accomplished internationally in the past decade to harmonise the much of the process of post-marketing drug risk detection. However, formidable challenges exist in harmonising analytical approaches to such data and in leveraging international database resources to improve the quality of such data. In addition, international challenges continue in the arena of drug risk management once a specific risk has been detected. Especially problematic are the questions of appropriate methodology and metrics to assess the public health impact of our risk management techniques. Finally, international challenges remain in the world of drug risk communication to practitioners, dispensers, and patients. The primary challenge confronting us is that of providing easily accessible, understandable, unbiased information on drug risk to these communities so that truly informed decisions about medicines can be made at the individual patient level. Only by meeting internationally these challenges in drug risk detection, management, and communication can our citizens know how to best use these wonderful pharmacological gifts to which we now have access.

  5. Ministerial presentation: Republic of Korea [International ministerial conference on nuclear power for the 21st century

    International Nuclear Information System (INIS)

    His Excellency Myung Oh, Deputy Prime Minister and Minister of Science and Technology, Republic of Korea, noted that the peaceful use of nuclear energy has contributed greatly to a sustainable and stable supply of energy over the past 50 years. Over the last two decades energy and electricity consumption in the Republic of Korea (ROK) has increased more than fivefold and sevenfold, respectively, and the ROK is now one of the top ten energy consuming economies. Furthermore, it is expected that the consumption of energy and electricity will continue to rise by 50% and 70%, respectively, by 2020. Given the scarce indigenous energy resources available in the ROK, he stated his firm belief that the application of nuclear energy is inevitable for future economic development. The ROK has recently launched national research and development projects to develop the VHTR (very high temperature reactor), which can produce high temperatures for hydrogen production by nuclear power. He predicted another nuclear renaissance in the future. For this, the global community should assign a larger role to nuclear energy in, for example, space heating, hydrogen production, vehicle propulsion and seawater desalination, and expand the application of radioisotopes to various industries. He confirmed that peaceful uses of nuclear energy are inevitable and indispensable options for the reduction of greenhouse gas emissions and future welfare. He stated that the ROK appreciates the international nuclear society's efforts in strengthening the non-proliferation regime, and commented that in the ROK there have been various measures in this regard, including reinforcement of an export control regime and IAEA safeguard measures. He also indicated that recently the ROK has expanded nuclear research and development activities for the innovation of nuclear technologies and enhanced international cooperation by joining international nuclear cooperation projects, such as GIF (Generation IV

    Over the past fifty years, countless billions of dollars and innumerable person-years of effort have been expended on international development. Sadly, what the development industry has to show for its labors is a present-day situation that is by many standards worse off in terms of total human misery than when they began. The shortcomings of international development are well documented. This is not to say that successes have not been achieved. They have; some have been quite significant. Rather, it is to say that development is much easier said than done. For science to have an impact on the wretched conditions evidenced throughout much of today’s developing and transition world, scientific organizations interested in making such a contribution must understand the realities of development. Biotechnology, fuel cells, the Internet, etc., hold much promise for pulling vast numbers of people out of the expansive morass of poverty. However, the development landscape is replete with botched “good ideas”. This session will, then, present the ways in which development has been and continues to be approached, the lessons learned from these experiences, and a framework for development assistance that can be used to guide the scientific community’s efforts to impact positively on the developing and transition world.

He noted that most activities in the nuclear field in Egypt have been supported by the IAEA through technical cooperation programmes. He commented that Egypt highly appreciates the continuous technical support from the IAEA and is looking forward to continue this fruitful cooperation in areas of the peaceful uses of nuclear energy. He reminded the conference that one of the challenges to be faced is ensuring nuclear security and non-proliferation and that Egypt has strongly supported the non-proliferation system from an early stage. He indicated that in this regard President Mubarak launched in April 1990 an initiative to make the Middle East free from weapons of mass destruction and looked for international support for this initiative

    The ability of scientists to communicate across cultural and linguistic barriers is crucial for the global economic sustainability and protection of the world\\'{}s oceans. Yet students with majors in the sciences and engineering constitute less than 2% of those who study abroad each year. And even rarer are students who study in countries where English is not the first language. The Marine Language Exchange program is a case study of an international and interdisciplinary collaboration between faculties in the languages and the sciences who address this gap. A consortium of U.S. and European institutions including Eckerd College (Florida), University of Washington (Washington), University of Hilo (Hawaii), Université de la Rochelle (France), Université de Liège (Belgium), and Universidad de Las Palmas (Spain) is developing a multilingual, marine sciences exchange program in an effort to internationalize their Marine Sciences departments. The program includes a three-week, intensive "bridge" course designed to reinforce second language skills in the context of marine sciences, and prepare undergraduate students for the cultural and educational differences of their host country. Following this immersion experience students from each institution enroll in courses abroad including marine sciences specialization for full academic credit. This session will review the Marine Language Exchange program activities since 2000 and will discuss the ideological and practical aspects of the program. The program successes, difficulties and future directions will also be presented. Different disciplinary approaches -Second Language Acquisition, English as a Second Language and Marine Science- prepare science students to contribute to the study and the management of the world\\'{}s oceans with an awareness of the cultural issues reflected by national marine policies. Based on this case study, other universities could initiate their own international and interdisciplinary

For each study, we compared the SGA prevalence and the risk ratio between SGA status and neonatal mortality, calculated using Poisson regression with robust error...... variance. MAIN OUTCOMES AND MEASURES: We examine neonatal mortality (death within the first 28 days after birth) as the main outcome measure. RESULTS: The pooled SGA prevalence was 23.7% (95% CI, 16.5%-31.0%) using the INTERGROWTH-21st standard compared with 36.0% (95% CI, 27.0%-45.0%) with the US 2000...

    Pelton, Joseph N.

    1996-02-01

    This paper addresses the changing international communications environment and explores the key elements of a new policy framework for the 21st Century. It addresses the issues related to changing markets, trade considerations, standards, regulatory changes and international institutions and law. The most important aspects will related to new international policy and regulatory frameworks and in particular to a new international code of ethics and behavior in the field of satellite communications. A new communications satellite policy framework requires systematically addressing the following points: • Multi-lateral agreements at the nation state and the operating entity level • Systematic means to access both private and public capital • Meshing ITU regulations with regional and national policy guidelines including • landing rights" and national allocation procedures. • Systematic approach to local partnerships • Resolving the issue of the relative standing of various satellite systems (i.e. GEO, MEO, and LEO systems) • Resolving the rights, duties, and priorities of satellite facility providers versus types of service prviders. Beyond this policy framework and generalized legal infrastructure there is also another need. This is a need that arises from both increased globalism and competitive international markets. This is what might quite simply be called a "code of reasonable conduct:" To provide global and international communications services effectively and well in the 21st Century will require more than meeting minimum international legal requirements. A new "code of conduct" for global satellite communications will thus likely need to address: • Privacy and surveillance • Ethics of transborder data flow • Censorship and moral values • Cultural and linguistic sensitivity • Freedom of the press and respect for journalistic standards As expanding global information and telecommunications systems grow and impact every aspect of modern

    2007-01-01

    New focus on the internationalization of universities occurred in the late 20th century and higher education in nursing has been quick to embrace the opportunities. In this manuscript, writers provide a brief overview of the nursing and more general literature from the late 20th century relating to key dimensions of internationalization, as well as present data from a survey conducted in 1995-96 of the international activities and dimensions at Canadian faculties/schools of nursing. While it is clear that nurses in Canadian universities were engaged in significant international endeavours in the 20th century, the literature and our experience suggest that the extent of such activity has increased substantially in recent years. Discussion centres on examination of how knowledge generated in the 20th century can inform current internationalization initiatives and on identification of key questions that merit consideration as we move forward in the 21st century.

  14. The 21st Century as Whose Century?

    2015-08-01

    Full Text Available Macro-analysis and East-West encounter are shown through consideration of objective yet subjective constructed concepts for the international system and international economy in the 21st century. Three paradigms are considered, namely the 21st century as the ‘Pacific Century’, as ‘China’s Century’ and as the ‘Asian Century’. Overlaps are shown between these three paradigms, as also developments in time, and gradually shift in geographical location. The ‘Pacific Century’, and its associated Rimspeak, was the paradigm emerging in the late 1970s, knitting together America’s West Coast and the Japanese economy. By the late 1980s this was already shifting to talk of the 21st century likely to be an ‘Asian Century’ model, mark-1, based on the Pacific Asia dynamism shown by the ‘Asian Tigers’ and Japan. However, the Asian financial crash of 1997-8, and the economic downturn in Japan, meant that such an ‘Asian Century’ seemed premature as the 21st century arrived. Instead, it was China’s economic growth that seemed most evident, and with it the concept of the 21st century as ‘China’s Century’. However, in turn that has already been modified during the first decade of the century by India’s arrival as a rapidly growing economy. Consequently the 21st century as ‘China’s Century’ and as ‘India’s Century’ has been combined into talk of an ‘Asian Century’, mark-2.

  17. Measuring up to the challenges of the 21st century. An international evaluation of the Centre for Metrology and Accreditation

    Energy Technology Data Exchange (ETDEWEB)

    Clapman, P.; Kaarls, R.; Temmes, M.

    1997-04-01

    The international evaluation of the Centre for Metrology and Accreditation (MIKES) is part of the process in which all relevant industrial and technology policy measures and organizations under the auspices of the Ministry of Trade and Industry (MTI) are being evaluated with the aim of improving their effectiveness. The overall conclusion of the evaluation is that MIKES is serving the country well. An effective national measurement system (FINMET) is being maintained which provides a wide range of calibration services covering most of the nation`s needs. The accreditation service (FINAS) is now well established, is operating effectively, and has good prospects for growth. The evaluators present, however, a number of proposals (including 33 specific recommendations) where they feel that the metrology and accreditation arrangements could be better-suited to meet future national and international challenges. According to the recommendations the Finnish quality policy framework should be developed in a consistent way. There is a need of a comprehensive governmental quality policy statement upon which the inter-ministry coordination and harmonization of various conformity assessment activities can be based. MIKES should retain its current status as an agency within MTI. The national measurement system should be more centralised and a new purpose-built national standards laboratory should be procured. The responsibility for legal metrology should be transferred to MIKES. The terms of reference and membership of Advisory Committee for Metrology, as well as the Advisory Committee for Accreditation should be revised to ensure wider representation of all relevant, and especially industrial interests

  20. Keynote speech by Angel Gurria, OECD Secretary-General, at the International Ministerial Conference on Nuclear Energy in the 21st Century

    International Nuclear Information System (INIS)

    The global crisis has exposed not only the paramount challenges of today's global economy and the remarkable level of interdependence among our nations. It has also confronted us with our duty to define the kind of global economy we need for tomorrow. It is our responsibility to devise sound policies for a stronger, cleaner and fairer global economy. Clean and affordable energy, including access to safe and secure nuclear power, should be a central element of our efforts. This is essential not only for a sustainable economy, but also for the future of our planet. The crisis has prompted us to act immediately and in concert. Take the example of our hosts, the People's Republic of China. In the face of the economic slowdown, they responded rapidly and in a comprehensive fashion. Importantly, they increased government spending, stimulated domestic demand and are looking into effective ways to enhance social policies. The turmoil showed that China and all of us need to be more involved in international economic co-operation. We are profoundly affected by the policies implemented by each of our countries. There is no better example than energy to illustrate our interdependence. Holding this meeting in Beijing shows the importance China places in international co-operation and recognises the role China could play in designing clean and safe energy solutions for the future. For me, coming to Beijing is also an opportunity to stress the high significance of the OECD partnership with China. Our Organisation is now more open and plural, welcoming new members and having launched an 'enhanced engagement' process with the most important emerging economies. Forging a more structured and stronger partnership with China is fundamental in such a process. It is based on our mutual interest to develop global solutions to global challenges, such as nuclear energy in the 21st century. Thus, I urge you to look into three important issues, which we should address in the years to come

    2012-08-01

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

    An overview of the importance of fossil fuels in supplying the energy requirements of the 21st century, their future supply, and the impact of their use on global climate is presented. Current and potential alternative energy sources are considered. It is concluded that even with substantial increases in energy derived from other sources, fossil fuels will remain a major energy source for much of the 21st century and the sequestration of CO2 will be an increasingly important requirement.

  15. Environmental issues in the 21st century

    International Nuclear Information System (INIS)

    Environmental issues in the 21st century D.B. Chambers SENES Consultants Limited, Richmond Hill, Ontario, Canada Abstract. This paper provides an overview of some of the environmental challenges facing the uranium production industry in the 21st century. For many years, the linear, non-threshold (LNT) model has been regarded as a prudent hypothesis for radiation protection purposes. This paradigm has been challenged at the same time for both underestimating and overestimating the risks from ionizing radiation. The reality is that the ability of conventional epidemiology to distinguish small risks will always be limited by statistical power at low doses. In the future, there will be increased emphasis on better understanding the effects of ionizing radiation at the cellular (and sub cellular) level. The concept of 'controllable dose' has been proposed as an alternative to the International Commission on Radiological Protection's (ICRP) current approach to dose limitation. The concept is that if the most exposed individual is protected, then society as a whole is protected. A hazard ranking scale based on comparisons to natural background levels of radiation has been proposed. Adoption of a concept such as 'controllable dose' would require a parallel re-evaluation of the concepts and application of collective dose and ALARA optimization. The protection of non-human biota is an issue of considerable interest in many countries. The science in this area is rapidly evolving, as are discussions of a more philosophical nature. For example, should the focus of environmental risk assessment be the sustainability of the population or should the focus be to limit effects on a single member of the population? The future of environmental risk assessment should be of great interest to the uranium production industry. A systematic approach to risk assessment addressing the full scope of potential hazards -- environmental, human health, engineering, financial and others -- will be

  19. Genome Evolution in the 21st Century

    Science.gov (United States)

    Shapiro, James

    2006-03-01

    Assume no previous theories about genetics and evolution. What conclusions would we draw from molecular data (e.g. genome sequences)? We start from basic principles of cellular information processing: cells behave cognitively using signal transduction networks; signal transduction involves weak noncovalent interactions; allosteric properties of biomolecules; multivalent storage of information in DNA sequences and nucleoprotein complexes; inertness of naked DNA. Genome informatics thus requires formation of nucleoprotein complexes. Complex formation requires generic repeated signals in the DNA; repetition also permits cooperativity to stabilize weak interactions. DNA is a functional structural component of nucleoprotein complexes, not a passive data tape. Specificity in DNA nucleoprotein complex formation involves combining multiple generic signals and/or sequence recognition by small RNAs. Novel combinations of generic signals and coding sequences arise in genomes by iteration and rearrangement. Cells possess natural genetic engineering functions that actively restructure DNA molecules. These internal DNA remodeling functions act cognitively in response to internal and external inputs. They operate non-randomly with respect to (1) the types of new structures produced and (2) the regions of the genome modified. Whole genome sequence data increasingly documents the historical role of natural genetic engineering in evolutionary changes. Basic principles of cellular molecular biology and DNA function lead to a complex interactive systems view of genome organization. This view incorporates different DNA components found in sequenced genomes. Regulated cellular natural genetic engineering functions permit genomes to serve as Read-Write information storage systems, not just Read-Only memories subject to accidental change. These 21st Century conclusions are most compatible with a systems engineering view of the evolutionary process.

  3. Nuclear power in the 21st century

    International Nuclear Information System (INIS)

    Full text: All plausible long term energy scenarios project significant growth of global energy, especially if the Millennium Declaration on poverty eradication and the Plan of Implementation agreed at the World Summit on Sustainable Development (WSSD) are to be met. Projected growth is the fastest in developing countries. While growth for affordable energy services is not subject to debate really - the question is rather by how much - this is not the case for energy supply. 21st century energy supply systems face several challenges and uncertainties including energy resource availability, technology change, environmental compliance, reliability and security, political and social acceptance. One of the uncertainties concerns the role of nuclear power in 21st century energy supplies. Paradoxically, its near term role appears less certain that its longer term role. In the short-run, i.e., until 2020, most studies project either a slight increase, a slight decrease or no change at all. Though regional differences exist in terms of growth and decline, the effectively balance each other. Longer-term energy demand and supply studies, however, paint a different future. Analyses developed by international working groups generally project a potentially significant increase in the use of nuclear power. There are several reasons for this. Foremost, longer-term studies are not subjected to short-term policy constraints. Next, they do factor anticipated technology change and innovation into the analysis. Then resource depletion effects become more visible and environmental constraints become more stringent. The starting point of this paper is the Special Report on Emissions Scenarios (SRES) of the Intergovernmental Panel on Climate Change. Based on four of the SRES scenarios, one from each of the four SRES scenario families, this paper discusses the compatibility requirements of each for nuclear energy in terms of economics, environment, supply security, resources, waste

    This Topical Issue contains works presented at the 21st Nordic Semiconductor Meeting (21NSM) held at Sundvolden, Norway, 18-19 August 2005. The institutions supporting 21NSM were: University of Oslo, SINTEF, the Norwegian Defense Research Establishment and Vestfold University College. The Nordic Semiconductor Meeting has become an international forum that has been held every other year in a relay fashion in Denmark, Finland, Iceland, Norway and Sweden. The focus of the meeting has been on original research and science being carried out on semiconductor materials, devices and systems. Reports on industrial activity have usually been featured at the meetings. The topics have ranged from fundamental research on point defects in a semiconductor to system architecture of semiconductor electronic devices. For the last five meetings the proceedings have been printed in a dedicated volume of Physica Scripta in the Topical Issue series. The papers in this Topical Issue have undergone critical peer review and we wish to thank the reviewers and the authors for their cooperation, which has been instrumental in meeting the expected high standards of the series. The range of topics covered by this volume is broad, reflecting the call for papers; most of the papers have an element of materials science and the largest portion of these deal with other semiconductor materials other than silicon.

    2003-08-01

    Toward the end of the twentieth century, it became evident to professionals working within the meterological arena that the world's climate system was showing signs of change that could not be adequately explained in terms of natural variation. Since that time there has been an increasing recognition that the climate system is changing as a result of human industries and lifestyles, and that the outcomes may prove catastrophic to the world's escalating population. Compiled by an international team formed under the auspices of the World Meteorological Organization (WMO), Climate: Into the 21st Century features an unrivalled collection of essays by the world's leading meteorological experts. These fully integrated contributions provide a perspective of the global climate system across the twentieth century, and describe some of the most arresting and extreme climatic events and their effects that have occurred during that time. In addition, the book traces the development of our capabilities to observe and monitor the climate system, and outlines our understanding of the predictability of climate on time-scales of months and longer. It concludes with a summary of the prospects for applying the twentieth century climate experience in order to benefit society in the twenty-first century. Lavishly illustrated in color, Climate is an accessible acccount of the challenges that climate poses at the start of the twenty-first century. Filled with fascinating facts and diagrams, it is written for a wide audience and will captivate the general reader interested in climate issues, and will be a valuable teaching resource. William Burroughs is a successful science author of books on climate, including Weather (Time Life, 2000), and Climate Change: A Multidisciplinary Approach (2001), Does the Weather Really Matter? (1997) and The Climate Revealed (1999), all published by Cambridge University Press.

  13. Nuclear Power in the 21st Century

    International Nuclear Information System (INIS)

    The International Atomic Energy Agency helps its Member States to use nuclear technology for a broad range of peaceful purposes, one of the most important of which is generating electricity. The accident at the Fukushima Daiichi nuclear power plant in Japan in March 2011 caused anxiety about nuclear safety throughout the world and raised questions about the future of nuclear power. Two years on, it is clear that the use of nuclear power will continue to grow in the coming decades, although growth will be slower than was anticipated before the accident. Many countries with existing nuclear power programmes plan to expand them. Many new countries, both developed and developing, plan to introduce nuclear power. The factors contributing to this growing interest include increasing global demand for energy, as well as concerns about climate change, volatile fossil fuel prices, and security of energy supply. It will be difficult for the world to achieve the twin goals of ensuring sustainable energy supplies and curbing greenhouse gases without nuclear power. The IAEA helps countries that opt for nuclear power to use it safely and securely. Countries that have decided to phase out nuclear power will have to deal with issues such as plant decommissioning, remediation, and waste management for decades to come. The IAEA also assists in these areas. I am grateful to the Russian Federation for hosting the 2013 International Ministerial Conference on Nuclear Power in the 21st Century in St Petersburg in June. This timely conference provides a valuable opportunity to take stock of nuclear power in the wake of the Fukushima Daiichi accident. A high level of public confidence in the safety of nuclear power is essential for the future of the sector. Much valuable work has been done in the past two years to improve safety. But much remains to be done. It is vitally important that the momentum is maintained and that everything is done to ensure that nuclear power is as safe as humanly

    2001-03-01

    Full Text Available Detergents of the 21st century will depend on evolutions in household appliances, in substrates and in consumer needs. In addition, the environmental constraints, which become more and more stringent, will also play an important role, particularly in the formulations. Surfactants, which constitute one of the main raw materials in detergents, will have to be more environmentally friendly with increasing criteria of biodegradability and renewable materials. Builders (phosphates or zeolithes, heavy metal complexants (EDTA and bleaching agents (combination perborate/TAED are also expected to be replaced by biodegradable compounds, with better performances and lower costs. The real raw materials of the detergents of the 21st century will probably be enzymes (oxidase, hydrolase, peroxidase which present several advantages. At the same time, efforts will be made on biodegradable packaging through the use of micro-organisms able to degrade polymers. Finally, in terms of product forms, the concept of concentration might come back through the use of tablets.

    Full Text Available Gallbladder cancer (GBC is an uncommon disease in the majority of the world despite being the most common and aggressive malignancy of the biliary tree. Early diagnosis is essential for improved prognosis; however, indolent and nonspecific clinical presentations with a paucity of pathognomonic/predictive radiological features often preclude accurate identification of GBC at an early stage. As such, GBC remains a highly lethal disease, with only 10% of all patients presenting at a stage amenable to surgical resection. Among this select population, continued improvements in survival during the 21st century are attributable to aggressive radical surgery with improved surgical techniques. This paper reviews the current available literature of the 21st century on PubMed and Medline to provide a detailed summary of the epidemiology and risk factors, pathogenesis, clinical presentation, radiology, pathology, management, and prognosis of GBC.

    This is an encore presentation of what was presented at the 2012 AGU International Conference. It was entitled: 'The Importance of Water Conservation in the 21st Century.' The poster presentation, however, has been redesigned and reorganized with new, revised perspectives. The importance of water conservation principles has been emphasized. The population of United States has more than doubled over the past 50 years. The need for water however, has tripled. The EPA estimates that more than 36 states face water shortage during the forthcoming years. The EPA has prepared a plan for achieving environmental and energy performance. This will be coupled with leadership and accountability. Carbon neutrality is also of prime importance. The objective is to focus on six important, essential areas. 1. Efficient use of already available energy resources. 2. Intelligent water consumption and focusing on water conservation. 3. Expand the use of renewable energy resources. 4. Explore innovative transportation systems and methodologies. 5. Change building codes and promote high performance sustainable buildings. 6. Focus on developing creative environment management systems. Greenhouse gases such as carbon dioxide occur naturally in the atmosphere. Carbon dioxide is also emitted to the atmosphere through a variety of natural processes and also some human activities. However, fluorinated gases are emitted to the atmosphere solely through human activities, because they are created by humans. It is very important to observe that water conservation is probably the most cost-effective way to reduce our demand for water. Furthermore, it is certainly environmentally justifiable. The Environmental Protection Agency has a plan called E2PLAN. It is EPA's plan for achieving energy and environmental performance, leadership, accountability, and carbon neutrality. In June 2011, the EPA published a comprehensive, multi-year planning document called Strategic Sustainability Performance Plan. The

    2012-12-01

    Growing pressure on the world's water resources is having major impacts on our social and economic well-being. According to the United Nations, today, at least 1.1 billion people do not have access to clean drinking water. Pressures on water resources are likely to continue to worsen in response to decaying and crumbling infrastructure, continued population growth, climate change, degradation of water quality, and other challenges. If these challenges are not addressed, they pose future risks for many countries around the world, making it urgent that efforts are made to understand both the nature of the problems and the possible solutions that can effectively reduce the associated risks. There is growing understanding of the need to rethink governance to meet the 21st century water challenges. More and more water problems extend over traditional national boundaries and to the global community and the types and numbers of organizations addressing water issues are large and growing. Economic globalization and transnational organizations and activities point to the need for improving coordination and integration on addressing water issues, which are increasingly tied to food and energy security, trade, global climate change, and other international policies. We will present some of the key limitations of global water governance institutions and provide recommendations for improving these institutions to address 21st century global water challenges more effectively.

  5. Nursing heroism in the 21st Century'

    Directory of Open Access Journals (Sweden)

    Darbyshire Philip

    2011-02-01

    Full Text Available Abstract Background The Vivian Bullwinkel Oration honours the life and work of an extraordinary nurse. Given her story and that of her World War II colleagues, the topic of nursing heroism in the 21st century could not be more germane. Discussion Is heroism a legitimate part of nursing, or are nurses simply 'just doing their job' even when facing extreme personal danger? In this paper I explore the place and relevance of heroism in contemporary nursing. I propose that nursing heroism deserves a broader appreciation and that within the term lie many hidden, 'unsung' or 'unrecorded' heroisms. I also challenge the critiques of heroism that would condemn it as part of a 'militarisation' of nursing. Finally, I argue that nursing needs to be more open in celebrating our heroes and the transformative power of nursing achievements. Summary The language of heroism may sound quaint by 21st Century standards but nursing heroism is alive and well in the best of our contemporary nursing ethos and practice.

    Federal laboratories have successfully filled many roles for the public; however, as the 21st Century nears it is time to rethink and reevaluate how Federal laboratories can better support the public and identify new roles for this class of publicly-owned institutions. The productivity of the Federal laboratory system can be increased by making use of public outcome metrics, by benchmarking laboratories, by deploying innovative new governance models, by partnerships of Federal laboratories with universities and companies, and by accelerating the transition of federal laboratories and the agencies that own them into learning organizations. The authors must learn how government-owned laboratories in other countries serve their public. Taiwan`s government laboratory, Industrial Technology Research Institute, has been particularly successful in promoting economic growth. It is time to stop operating Federal laboratories as monopoly institutions; therefore, competition between Federal laboratories must be promoted. Additionally, Federal laboratories capable of addressing emerging 21st century public problems must be identified and given the challenge of serving the public in innovative new ways. Increased investment in case studies of particular programs at Federal laboratories and research on the public utility of a system of Federal laboratories could lead to increased productivity of laboratories. Elimination of risk-averse Federal laboratory and agency bureaucracies would also have dramatic impact on the productivity of the Federal laboratory system. Appropriately used, the US Federal laboratory system offers the US an innovative advantage over other nations.

  8. Antiparasitic DNA vaccines in 21st century.

    Science.gov (United States)

    Wedrychowicz, Halina

    2015-06-01

    Demands for effective vaccines to control parasitic diseases of humans and livestock have been recently exacerbated by the development of resistance of most pathogenic parasites to anti-parasitic drugs. Novel genomic and proteomic technologies have provided opportunities for the discovery and improvement of DNA vaccines which are relatively easy as well as cheap to fabricate and stable at room temperatures. However, their main limitation is rather poor immunogenicity, which makes it necessary to couple the antigens with adjuvant molecules. This paper review recent advances in the development of DNA vaccines to some pathogenic protozoa and helminths. Numerous studies were conducted over the past 14 years of 21st century, employing various administration techniques, adjuvants and new immunogenic antigens to increase efficacy of DNA vaccines. Unfortunately, the results have not been rewarding. Further research is necessary using more extensive combinations of antigens; alternate delivery systems and more efficient adjuvants based on knowledge of the immunomodulatory capacities of parasitic protozoa and helminths.

    2004-07-01

    The Federal government plays a key role in supporting the country's science infrastructure, a national treasure, and scientific research, an investment in our future. Scientific discoveries transform the way we think about our universe and ourselves, from the vastness of space to molecular-level biology. In innovations such as drugs derived through biotechnology and new communications technologies we see constant evidence of the power of science to improve lives and address national challenges. We had not yet learned to fly at the dawn of the 20th century, and could not have imagined the amazing 20th century inventions that we now take for granted. As we move into the 21st century, we eagerly anticipate new insights, discoveries, and technologies that will inspire and enrich us for many decades to come. This report presents the critical responsibilities of our Federal science enterprise and the actions taken by the Federal research agencies, through the National Science and Technology Council, to align our programs with scientific opportunity and with national needs. The many examples show how our science enterprise has responded to the President's priorities for homeland and national security, economic growth, health research, and the environment. In addition, we show how the science agencies work together to set priorities; coordinate related research programs; leverage investments to promote discovery, translate science into national benefits, and sustain the national research enterprise; and promote excellence in math and science education and work force development.

  16. Ionizing radiation in 21st century

    International Nuclear Information System (INIS)

    The paper begins with the author's personal experience in Poland on the occasion of Chernobyl nuclear accident followed by main lessons that the author could deduce from the accident. After the discovery of ionizing radiation at the end of 19th century, social perception has altered between acceptance and rejection stemming from recognition of the basic aspects: usefulness for medical applications and for technical and scientific aims, beneficial effects of their low levels, and harmful effects of high levels. The author explains how linear no-threshold (LNT) assumption according to which even the lowest, near zero doses of radiation may cause cancer genetic harm has become established. Comparing the natural radioactivity of the earth's crust with the activity of much shorter-lived radioactive wastes from the nuclear power cycle, it is concluded that none of the man-made component of the radioactive wastes has higher-toxicity than the natural Th 232. The paper concludes by stating that one century has not been long enough to adapt mentally to ionizing radiation and radioactivity and perhaps 21st century will suffice for this adaptation. (S.

    2009-06-01

    Biofabrication can be defined as the production of complex living and non-living biological products from raw materials such as living cells, molecules, extracellular matrices, and biomaterials. Cell and developmental biology, biomaterials science, and mechanical engineering are the main disciplines contributing to the emergence of biofabrication technology. The industrial potential of biofabrication technology is far beyond the traditional medically oriented tissue engineering and organ printing and, in the short term, it is essential for developing potentially highly predictive human cell- and tissue-based technologies for drug discovery, drug toxicity, environmental toxicology assays, and complex in vitro models of human development and diseases. In the long term, biofabrication can also contribute to the development of novel biotechnologies for sustainable energy production in the future biofuel industry and dramatically transform traditional animal-based agriculture by inventing 'animal-free' food, leather, and fur products. Thus, the broad spectrum of potential applications and rapidly growing arsenal of biofabrication methods strongly suggests that biofabrication can become a dominant technological platform and new paradigm for 21st century manufacturing. The main objectives of this review are defining biofabrication, outlining the most essential disciplines critical for emergence of this field, analysis of the evolving arsenal of biofabrication technologies and their potential practical applications, as well as a discussion of the common challenges being faced by biofabrication technologies, and the necessary conditions for the development of a global biofabrication research community and commercially successful biofabrication industry.

    We are truly fortunate to live in one of the great epochs of human discovery, a time when science is providing new visions and understanding about ourselves and the world in which we live. At last, we are beginning to explore the Universe itself. One particularly exciting area of advancement is high-energy physics where several existing concepts will be put to the test. A brief survey will be given of accomplishments in 20th Century physics. These include relativity and quantum physics which have produced breakthroughs in cosmology, astrophysics, and high-energy particle physics. The current situation is then assessed, combining the last 100 years of progress with new 21st Century challenges about unification and where to go next. Finally, the future is upon us. The next frontier in experimental high-energy physics, the Large Hadron Collider (LHC) at CERN in Geneva, is scheduled to begin coming online this year (2007). The potential for the LHC to address several of the significant problems in physics today will be discussed, as this great accelerator examines the predictions of the Standard Model of particle physics and even cosmology. New physics and new science will surely emerge and a better vision of the world will unfold.

    Biofabrication can be defined as the production of complex living and non-living biological products from raw materials such as living cells, molecules, extracellular matrices, and biomaterials. Cell and developmental biology, biomaterials science, and mechanical engineering are the main disciplines contributing to the emergence of biofabrication technology. The industrial potential of biofabrication technology is far beyond the traditional medically oriented tissue engineering and organ printing and, in the short term, it is essential for developing potentially highly predictive human cell- and tissue-based technologies for drug discovery, drug toxicity, environmental toxicology assays, and complex in vitro models of human development and diseases. In the long term, biofabrication can also contribute to the development of novel biotechnologies for sustainable energy production in the future biofuel industry and dramatically transform traditional animal-based agriculture by inventing 'animal-free' food, leather, and fur products. Thus, the broad spectrum of potential applications and rapidly growing arsenal of biofabrication methods strongly suggests that biofabrication can become a dominant technological platform and new paradigm for 21st century manufacturing. The main objectives of this review are defining biofabrication, outlining the most essential disciplines critical for emergence of this field, analysis of the evolving arsenal of biofabrication technologies and their potential practical applications, as well as a discussion of the common challenges being faced by biofabrication technologies, and the necessary conditions for the development of a global biofabrication research community and commercially successful biofabrication industry.

    Lithium is an important industrial compound and the principal component of high energy-density batteries. Because it is the lightest solid element, these batteries are widely used in consumer electronics and are expected to be the basis for battery electric vehicles (BEVs), hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs) for the 21st century. In view of the large incremental demand for lithium that will result from expanded use of various types of EVs, long-term estimates of lithium demand and supply are advisable. For GDP growth rates of 2 to 3% and battery recycling rates of 90 to 100%, total demand for lithium for all markets is expected to be a maximum of 19.6 million tonnes through 2100. This includes 3.2 million tonnes for industrial compounds, 3.6 million tonnes for consumer electronics, and 12.8 million tonnes for EVs. Lithium-bearing mineral deposits that might supply this demand contain an estimated resource of approximately 39 million tonnes, although many of these deposits have not been adequately evaluated. These lithium-bearing mineral deposits are of two main types, non-marine playa-brine deposits and igneous deposits. Playa-brine deposits have the greatest immediate resource potential (estimated at 66% of global resources) and include the Salar de Atacama (Chile), the source of almost half of current world lithium production, as well as Zabuye (China/Tibet) and Hombre Muerto (Argentina). Additional important playa-brine lithium resources include Rincon (Argentina), Qaidam (China), Silver Peak (USA) and Uyuni (Bolivia), which together account for about 35% of the estimated global lithium resource. Information on the size and continuity of brine-bearing aquifers in many of these deposits is limited, and differences in chemical composition of brines from deposit to deposit require different extraction processes and yield different product mixes of lithium, boron, potassium and other elements. Numerous other brines in playas

  4. Environmental issues in the 21st century

    International Nuclear Information System (INIS)

    This paper provides an overview of some of the environmental challenges facing the uranium production industry in the 21st century. For many years, the linear, non-threshold (LNT) model has been regarded as a prudent hypothesis for radiation protection purposes. This paradigm has been challenged at the same time for both underestimating and overestimating the risks from ionizing radiation. The reality is that the ability of conventional epidemiology to distinguish small risks will always be limited by statistical power at low doses. In the future, there will be increased emphasis on better understanding the effects of ionizing radiation at the cellular (and sub cellular) level. The concept of 'controllable dose' has been proposed as an alternative to the ICRP's current approach to dose limitation. The concept is that if the most exposed individual is protected, then society as a whole is protected. A hazard ranking scale based on comparisons to natural background levels of radiation has been proposed. Adoption of a concept such as 'controllable dose' would require a parallel re-evaluation of the concepts and application of collective dose and ALARA optimization. The protection of non-human biota is an issue of considerable interest in many countries. The science in this area is rapidly evolving, as are discussions of a more philosophical nature. For example, should the focus of environmental risk assessment be the sustainability of the population or should the focus be to limit effects on a single member of the population? The future of environmental risk assessment should be of great interest to the uranium production industry. A systematic approach to risk assessment addressing the full scope of potential hazards - environmental, human health, engineering, financial and others - will be increasingly important in the future. What level of risk is it reasonable to accept? What is meant by 'reasonable'? How much risk can be engineered away, for how long, and at what

    Geoscience knowledge and skills play new roles in the workforce as our society addresses the challenges of living safely and sustainably on Earth. As a result, we expect a wider range of future career opportunities for students with education in the geosciences and related fields. A workshop offered by the InTeGrate STEP Center on 'Geoscience and the 21st Century Workforce' brought together representatives from 24 programs with a substantial geoscience component, representatives from different employment sectors, and workforce scholars to explore the intersections between geoscience education and employment. As has been reported elsewhere, employment in energy, environmental and extractive sectors for geoscientists with core geology, quantitative and communication skills is expected to be robust over the next decade as demand for resources grow and a significant part of the current workforce retires. Relatively little is known about employment opportunities in emerging areas such as green energy or sustainability consulting. Employers at the workshop from all sectors are seeking the combination of strong technical, quantitative, communication, time management, and critical thinking skills. The specific technical skills are highly specific to the employer and employment needs. Thus there is not a single answer to the question 'What skills make a student employable?'. Employers at this workshop emphasized the value of data analysis, quantitative, and problem solving skills over broad awareness of policy issues. Employers value the ability to articulate an appropriate, effective, creative solution to problems. Employers are also very interested in enthusiasm and drive. Participants felt that the learning outcomes that their programs have in place were in line with the needs expressed by employers. Preparing students for the workforce requires attention to professional skills, as well as to the skills needed to identify career pathways and land a job. This critical

    Full Text Available Establishing a common strategic framework is a decisive factor in the Ukrainian-Polish relations in the current social and political context. The complexity of the partnership between the two states arise from their geographical location on the borderline between civilizations, the site of historical cataclysms. At the same time, national sovereignty of was always a high priority for both peoples. The recognition of Ukraine’s independence by Poland marked a new stage of rapprochement between Warsaw and Kyiv, the act being evidence of maturity of the Polish political elite. Poland made its best to promote the interest of Ukraine in the international political arena. The article suggests periodization in the history of the Ukrainian-Polish partnership. Ukrainian policy can be modelled on Poland’s experience of the transformation of society. Being a member of the European Union, Poland advocates the idea of European and Euro-Atlantic integration of Ukraine. Increased economic cooperation is one of the aspects of the Ukrainian-Polish partnership. Cooperation at regional level, between local government bodies is also important for the relations between the two states. Step by step, visa regulations are being liberalized, interpersonal contacts broadened. The beginning of the 21st century witnesses a change in political consciousness of Ukrainian and Polish people, who reconsider painful events from their past.

    2016-01-01

    Summary Understanding and preventing adverse impacts from chemicals in the environment is fundamental to protecting public health, and chemical risk assessments are used to inform public health decisions in the United States and around the world. Traditional chemical risk assessments focus on health effects of environmental contaminants on a chemical-by-chemical basis, largely based on data from animal models using exposures that are typically higher than those experienced by humans. Results from environmental epidemiology studies sometimes show effects that are not observed in animal studies at human exposure levels that are lower than those used in animal studies. In addition, new approaches such as Toxicology in the 21st Century (Tox21) and exposure forecasting (ExpoCast) are generating mechanistic data that provide broad coverage of chemical space, chemical mixtures, and potential associated health outcomes, along with improved exposure estimates. It is becoming clear that risk assessments in the future will need to use the full range of available mechanistic, animal, and human data to integrate multiple types of data and to consider nontraditional health outcomes and end points. This perspective was developed at the “Strengthening the Scientific Basis of Chemical Safety Assessments” workshop, which was cosponsored by the U.S. Environmental Protection Agency and the National Institute of Environmental Health Sciences, where gaps between the emerging science and traditional chemical risk assessments were explored, and approaches for bridging the gaps were considered.

    Melia, N.; Haines, K.; Hawkins, E.

    Climate models unanimously project a decline in the extent and thickness of Arctic sea ice as the climate warms, but at differing rates. Projecting the timing of an ice-free Arctic is a topic that has received considerable scientific and public attention. An ice-free Arctic opens up the potential for shorter global trade routes through the Arctic Ocean and there has already been a sharp increase in the number of transits along Russia's Northern Sea Route with escorts from nuclear powered icebreakers.Here we present results on the future of trans-Arctic shipping using bias corrected sea ice thickness projections, utilising the CMIP5 multi-model ensemble and considering multiple emission scenarios. We find that for 'Open Water' vessels (normal ocean going vessels that possess no specific ice strengthening), unaided trans-Arctic shipping is likely to become feasible in the next couple of decades. We find that the North West Passage will open approximately a decade later than the Northern Sea Route. Initially however, both routes exhibit marked inter-annual variability in accessibility which we quantify. The hypothesised trans-polar sea route through international waters via the North Pole will start to become navigable by 2050. Towards the latter period of the 21st century, normal ocean going vessels will be able to transit their choice of any of these routes for at least six months of any given year under the RCP 8.5 high future emissions scenario and four months for the lower RCP 4.5 emissions scenario. These findings suggest that further increases in global temperature could transform the Arctic into a global transport hub.

  14. Responsible Management Education for 21st Century Leadership

    Markus Prandini

    2012-09-01

    Full Text Available In the aftermath of the 2008/09 financial crisis, business schools had to face increasing criticism to have failed equipping their students with a broad and critical understanding of management and business practices which go beyond pure self-interest. Business schools are supposed to contribute to a holistic understanding of management which creates value along a triple bottom line: profit, people and planet. The triple bottom line finds its realization in the concept of sustainable corporate responsibility. This paper discusses possible approaches for business schools how to educate students to be future generators of sustainable value for business and society at large and to work for an inclusive and sustainable global economy. On the basis of the recently published Principles for Responsible Management Education (PRME as well as contemporary learning theories, the paper provides concrete recommendations how to foster students’ development towards long-term thinking, responsible business leaders. The paper argues that student learning needs to occur within powerful learning environments to provide an active, problem-based and self-directed acquisition of knowledge, skills and attitudes. Two approaches to create best-practice learning environments are real-life case studies and real-life student projects which both lead to a strong buy in of students, faculty and company partners. Both approaches are exemplified with the bachelor degree program International Management at the Zurich University of Applied Sciences (Switzerland. As a conclusion, a responsible management education fosters the students’ knowledge, skills and attitudes towards responsible business leadership to shape the future direction of the 21st century.

    Despite significant improvements in leprosy (Hansen's disease) treatment and outlook for patients since the introduction of multidrug therapy (MDT) 3 decades ago, the global incidence remains high, and patients often have long-term complications associated with the disease. In this article, we discuss recent findings related to genetics, susceptibility, and disease reservoirs and the implications of these findings for Hansen's disease control and health outcomes for patients. We describe the continued difficulties associated with treatment of inflammatory episodes known as "leprosy reactions," which cause much of the disability associated with the disease and can affect people for many years after MDT is complete. We also discuss some of the contemporary challenges for physicians and patients, including international and internal migration of people affected by the disease. We suggest some important areas of focus for future Hansen's disease research. PMID:25567223

  9. Magnets for the 21st century

    International Nuclear Information System (INIS)

    Based on a review of the development of laboratory electromagnets, perspectives for the next generation of pulsed magnets are discussed. Record fields are now approaching the 75T mark, and large efforts are made on an international scale in order to move into the region between 75 and 100T. Simple scaling laws indicate that these magnets will have a small bore and a short pulse duration of order 10ms. Fields above 100T are obtained by destructive methods, using high explosives (up to 2000T) and capacitor banks (up to 300T with the single turn coil and up to 600T with flux compression by implosion). The pulse duration is governed by shock waves, and therefore, restricted to the microsecond range. Efficient use of all these magnets calls for miniaturisation of both magnets and experiments, and the development of experimental techniques that are adapted to these conditions

    2016-07-01

    The internationalization of engineering curricula and engineering practices has begun in Europe, Anglosphere (English speaking) nations and Asian emerging economies through the Bologna Process and International Engineering Alliance (Washington Accord). Both the Bologna Process and the Washington Accord have introduced standardized outcome based engineering competencies and frameworks for the attainment of these competencies by restructuring existing and undertaking some new measures for an intelligent adaptation of the engineering curriculum and pedagogy. Thus graduates with such standardized outcome based curriculum can move freely as professional engineers with mutual recognition within member nations. Despite having similar or near similar curriculum, Bangladeshi engineering graduates currently cannot get mutual recognition in nations of Washington Accord and the Bologna Process due to the non-compliance of outcome based curriculum and pedagogy. This paper emphasizes the steps that are required to undertake by the engineering educational institutions and the professional body in Bangladesh to make the engineering competencies, curriculum and pedagogy compliant to the global engineering alliance. Achieving such compliance will usher in a new era for the global mobility and global engagement by Bangladesh trained engineering graduates.

This has resulted in many new books and teaching packages involving multi media presentation materials becoming available on the open market. Availability of computer software packages, originally developed for research purposes, has led to the introduction of solar system simulation into many engineering and architectural courses. Finally, as we move into the arena of the virtual school or university of the twenty first century, there is no doubt that more and more teaching and learning material will be made available free of charge on the world wide web, and that students worldwide will eventually have ease of access to academic and commercial information on a scale unimaginable only a few years ago.

  13. Glaciers in 21st Century Himalayan Geopolitics

    2002-05-01

    Glaciers are ablating rapidly the world over. Nowhere are the rates of retreat and downwasting greater than in the Hindu Kush-Himalaya (HKH) region. It is estimated that over the next century, 40,000 square kilometers of present glacier area in the HKH region will become ice free. Most of this area is in major valleys and the lowest glaciated mountain passes. The existence and characteristics of glaciers have security impacts, and rapidly changing HKH glaciers have broad strategic implications: (1) Glaciers supply much of the fresh water and hydroelectric power in South and Central Asia, and so glaciers are valuable resources. (2) Shared economic interests in water, hydroelectricity, flood hazards, and habitat preservation are a force for common cause and reasoned international relations. (3) Glaciers and their high mountains generally pose a natural barrier tending to isolate people. Historically, they have hindered trade and intercultural exchanges and have protected against aggression. This has further promoted an independent spirit of the region's many ethnic groups. (4) Although glaciers are generally incompatible with human development and habitation, many of the HKH region's glaciers and their mountains have become sanctuaries and transit routes for militants. Siachen Glacier in Kashmir has for 17 years been "the world's highest battlefield," with tens of thousands of troops deployed on both sides of the India/Pakistan line of control. In 1999, that conflict threatened to trigger all-out warfare, and perhaps nuclear warfare. Other recent terrorist and military action has taken place on glaciers in Kyrgyzstan and Tajikistan. As terrorists are forced from easily controlled territories, many may tend to migrate toward the highest ground, where definitive encounters may take place in severe alpine glacial environments. This should be a major concern in Nepali security planning, where an Army offensive is attempting to reign in an increasingly robust and brutal

    21st Century Kinematics focuses on algebraic problems in the analysis and synthesis of mechanisms and robots, compliant mechanisms, cable-driven systems and protein kinematics. The specialist contributors provide the background for a series of presentations at the 2012 NSF Workshop. The text shows how the analysis and design of innovative mechanical systems yield increasingly complex systems of polynomials, characteristic of those systems. In doing so, takes advantage of increasingly sophisticated computational tools developed for numerical algebraic geometry and demonstrates the now routine derivation of polynomial systems dwarfing the landmark problems of even the recent past. The 21st Century Kinematics workshop echoes the NSF-supported 1963 Yale Mechanisms Teachers Conference that taught a generation of university educators the fundamental principles of kinematic theory. As such these proceedings will be provide admirable supporting theory for a graduate course in modern kinematics and should be of consid...

    Full Text Available Information and communication technologies will undoubtely be leading determinants of urban landscape in the 21st century. Until the present day, it was assumed that urban landscapes were being shaped by conventional factors such as demography, social and economical structure, transportion, infrastructure, building technologies etc. In spite of many speculative approaches, recent developments in information and communication technologies can offer us some clues which may go beyond mere speculation. The“intelligent city” which is based on “autonomous” and “intelligent” objects and agents promising novel solutions to urban problems. Mobile communication is also another promising domain to offer creative solutions to some cronical urban problems. All these novelties provide sufficient reasons to think about new urban structures based upon information technologies.This paper is an attempt to discuss probable effects of information technologies, as new dynamics to shape the urban environment and urban life of the 21st century.

  6. How 21st century droughts affect food and environmental security

    Science.gov (United States)

    Kogan, Felix

    The first 13th years of the 21st century has begun with a series of widespread, long and intensive droughts around the world. Extreme and severe-to-extreme intensity droughts covered 2-6% and 7-16% of the world land, respectively, affecting environment, economies and humans. These droughts reduced agricultural production, leading to food shortages, human health deterioration, poverty, regional disturbances, population migration and death. This presentation is a travelogue of the 21st century global and regional droughts during the warmest years of the past 100 years. These droughts were identified and monitored with the NOAA operational space technology, called Vegetation Health (VH), which has the longest period of observation and provide good data quality. The VH method was used for assessment of vegetation condition or health, including drought early detection and monitoring. The VH method is based on operational satellites data estimating both land surface greenness (NDVI) and thermal conditions. The 21st century droughts in the USA, Russia, Australia Argentina, Brazil, China, India and other principal grain producing countries were intensive, long, covered large areas and caused huge losses in agricultural production, which affected food and environmental security and led to food riots in some countries. This presentation investigate how droughts affect food and environmental security, if they can be detected earlier, how to monitor their area, intensity, duration and impacts and also their dynamics during the climate warming era with satellite-based vegetation health technology.

  8. International conference: nuclear power for the 21 st century

    International Nuclear Information System (INIS)

    It is widely recognised that global energy demand will rise substantially during this century. The increased industrialization and urbanization of developing countries will produce large increases in energy demand in regions that currently have very low per capita energy use. This increasing demand for energy will need to be met in order to improve living standards for at least half of the world population and to reduce the economic imbalances between countries and regions. At the same time the use of fossil fuel based energy is identified as a major cause of environmental damage. The release of greenhouse gases from burning of fossil fuel in power stations and for transport is seen as a contributor to global warming. It is widely recognised that continued exploitation of fossil fuels and release of carbon dioxide will need to be controlled. After a prolonged period of slow development of nuclear power, confined to some countries in the world, it is now being recognised that nuclear energy has a potentially significant role to play in meeting the energy needs of the planet without damaging the environment. Developments in technology make the economics of nuclear power more attractive, and they may become even more so as fossil fuel prices continue to rise.or a widespread use of nuclear power, however, there remain concerns on the safety, security, waste and proliferation aspects. The global application of safety standards and appropriate security measures are required to ensure acceptable levels of protection. Effective control measures are required to ensure that non-proliferation commitments are honored. Handling nuclear waste safely and securely is achievable, but continues to remain as a public concern. The broad strategic objectives of the Conference are the following: to review the role of nuclear power and to define the potential benefits (energy security, sustainability and improved environmental protection) that expanding nuclear power offers to meet the increasing energy needs of the world; to facilitate a discussion on the issue of nuclear energy and society involving experts and decision makers.

    One of the main objectives of the Spanish and Portuguese-Speaking Group of the International Society for Forensic Genetics (GHEP-ISFG) is to promote and contribute to the development and dissemination of scientific knowledge in the area of forensic genetics. Due to this fact, GHEP-ISFG holds different working commissions that are set up to develop activities in scientific aspects of general interest. One of them, the Mixture Commission of GHEP-ISFG, has organized annually, since 2009, a collaborative exercise on analysis and interpretation of autosomal short tandem repeat (STR) mixture profiles. Until now, three exercises have been organized (GHEP-MIX01, GHEP-MIX02 and GHEP-MIX03), with 32, 24 and 17 participant laboratories respectively. The exercise aims to give a general vision by addressing, through the proposal of mock cases, aspects related to the edition of mixture profiles and the statistical treatment. The main conclusions obtained from these exercises may be summarized as follows. Firstly, the data show an increased tendency of the laboratories toward validation of DNA mixture profiles analysis following international recommendations (ISO/IEC 17025:2005). Secondly, the majority of discrepancies are mainly encountered in stutters positions (53.4%, 96.0% and 74.9%, respectively for the three editions). On the other hand, the results submitted reveal the importance of performing duplicate analysis by using different kits in order to reduce errors as much as possible. Regarding the statistical aspect (GHEP-MIX02 and 03), all participants employed the likelihood ratio (LR) parameter to evaluate the statistical compatibility and the formulas employed were quite similar. When the hypotheses to evaluate the LR value were locked by the coordinators (GHEP-MIX02) the results revealed a minor number of discrepancies that were mainly due to clerical reasons. However, the GHEP-MIX03 exercise allowed the participants to freely come up with their own hypotheses to

The National Science Foundation's Very Large Array (VLA) radio telescope now has half of its giant, 230-ton dish antennas converted to use new, state-of-the-art digital electronics to replace analog equipment that has served since the facility's construction during the 1970s. VLA and Radio Galaxy VLA Antennas Getting Modern Electronics To Meet New Scientific Challenges CREDIT: NRAO/AUI/NSF Click on image for more information, higher-resolution files "We're taking a facility that has made landmark discoveries in astronomy for three decades and making it 10 times more powerful, at a cost that's a fraction of its total value, by replacing outdated technology with modern equipment," said Mark McKinnon, project manager for the Expanded VLA (EVLA). Rick Perley, EVLA project scientist, added: "When completed in 2012, the EVLA will be 10 times more sensitive, cover more frequencies, and provide far greater analysis capabilities than the current VLA. In addition, it will be much simpler to use, making its power available to a wider range of scientists." The EVLA will give scientists new power and flexibility to meet the numerous challenges of 21st-Century astrophysics. The increased sensitivity will reveal the earliest epochs of galaxy formation, back to within a billion years of the Big Bang, or 93 percent of the look-back time to the beginning of the Universe. It will have the resolution to peer deep into the dustiest star-forming clouds, imaging protoplanetary disks around young stars on scales approaching that of the formation of terrestrial planets. The EVLA will provide unique capabilities to study magnetic fields in the Universe, to image regions near massive black holes, and to systematically track changes in transient objects

  11. The 21st century decline in damaging European windstorms

    Science.gov (United States)

    Dawkins, Laura C.; Stephenson, David B.; Lockwood, Julia F.; Maisey, Paul E.

    2016-08-01

    A decline in damaging European windstorms has led to a reduction in insured losses in the 21st century. This decline is explored by identifying a damaging windstorm characteristic and investigating how and why this characteristic has changed in recent years. This novel exploration is based on 6103 high-resolution model-generated historical footprints (1979-2014), representing the whole European domain. The footprint of a windstorm is defined as the maximum wind gust speed to occur at a set of spatial locations over the duration of the storm. The area of the footprint exceeding 20 ms-1 over land, A20, is shown to be a good predictor of windstorm damage. This damaging characteristic has decreased in the 21st century, due to a statistically significant decrease in the relative frequency of windstorms exceeding 20 ms-1 in north-western Europe, although an increase is observed in southern Europe. This is explained by a decrease in the quantiles of the footprint wind gust speed distribution above approximately 18 ms-1 at locations in this region. In addition, an increased variability in the number of windstorm events is observed in the 21st century. Much of the change in A20 is explained by the North Atlantic Oscillation (NAO). The correlation between winter total A20 and winter-averaged mean sea-level pressure resembles the NAO pattern, shifted eastwards over Europe, and a strong positive relationship (correlation of 0.715) exists between winter total A20 and winter-averaged NAO. The shifted correlation pattern, however, suggests that other modes of variability may also play a role in the variation in windstorm losses.

    2001-01-01

    The 21st Century is the time for human seeking harmonizing with environment and carrying out sustainable development strategy. But sustainable development is facing many challenges. They may mainly include the follows: challenge comes from the contradiction between human and the earth, challenge of local benefit conflict to human common goal, challenge of competition to fairness, challenge of unbalanced development in regions and countries, challenge of diversity and challenge of calamity. Challenges are not only pressure, but also the motive force. Challenge exists, the motive force would never stop. Sustainable development was born in challenges, is developing in contradiction and will sustain in conflict.

    Libraries and librarians have been defined by the book throughout modern history. What happens when society increasingly lets print go in favour of storing, retrieving and manipulating electronic information? What happens after the book? After the Book explores how the academic library of the 21st Century is first and foremost a provider of electronic information services. Contemporary users expect today's library to provide information as quickly and efficiently as other online information resources. The book argues that librarians need to change what they know, how they work, and how they ar

    2000-01-01

    Evidence on a broad range of time scales, from Proterozoic to the most recent periods, shows that the Earth's climate responds sensitively to global forcings. In the past few decades the Earth's surface has warmed rapidly, apparently in response to increasing anthropogenic greenhouse gases in the atmosphere. The conventional view is that the current global warming rate will continue or accelerate in the 21st century. I will describe an alternate scenario that would slow the rate of global warming and reduce the danger of dramatic climate change. But reliable prediction of future climate change requires improved knowledge of the carbon cycle and global observations that allow interpretation of ongoing climate change.

    Full Text Available The latest four decades have marked by their width, speed and radicality a true “revolution” on the financial market, a transformation and restructuring of financial services, of financial instruments which were used, of transaction systems, but also of competitive processes. The importance that should be given to such transformations of financial systems is given, as well, by their impact, both at the micro- and at the macro- levels, on the economy as a whole.The evolution of the European financial market at the beginning of the 21st century has followed the general trend of global markets. As a main tendency of financial market restructuring at the European level we should keep in mind the fact that there was an opening towards private financing according to the American model, due to the necessity to attract international capital resources, a process which is still ongoing.The integration of the European financial markets at the beginning of the 21st century follows the general process of financial globalization which develops rapidly on several structures of financial systems.

    In the spring of 2009, I participated in PolarTREC - Teachers and Researchers Exploring and Collaborating, a Teacher Research Experience (TRE) funded by the National Science Foundation and managed by the Arctic Research Consortium of the United States. I assisted in hands-on research being performed by scientists with OASIS (Ocean, Atmosphere, Sea Ice and Snowpack) during their field campaign in Barrow, Alaska. Although I was in the field for only 3 weeks, it was merely a beginning to a transformation that took place not only in me, but also among all of those involved. The PolarTREC program embodies the principles fundamental to the 21st Century skill-set that we want our students to possess. The job market is changing for graduates, and education is striving to provide students with the skills necessary to thrive in the future. To ensure the success of students the International Society for Technology Education (ISTE) has defined 21st Century Skills. They are incorporated into many educational standards (such as the Arizona Educational Technology Standards) and they are practiced by the teachers, researchers, students and the PolarTREC community. They are: Creativity and Innovation Communication and Collaboration Research and Information Literacy Critical Thinking, Problem Solving, and Decision Making Digital Citizenship Technology Operations and Concepts

    Future stratospheric ozone concentrations will be determined both by changes in the concentration of ozone depleting substances (ODSs) and by changes in stratospheric and tropospheric climate, including those caused by changes in anthropogenic greenhouse gases (GHGs). Since future economic development pathways and resultant emissions of GHGs are uncertain, anthropogenic climate change could be a significant source of uncertainty for future projections of stratospheric ozone. In this pilot study, using an ensemble of opportunity of chemistry-climate model (CCM) simulations, the contribution of scenario uncertainty from different plausible emissions pathways for 10 ODSs and GHGs to future ozone projections is quantified relative to the contribution from model uncertainty and internal variability of the chemistry-climate system. For both the global, annual mean ozone concentration and for ozone in specific geographical regions, differences between CCMs are the dominant source of uncertainty for the first two-thirds of the 21 st century, up-to and after the time when ozone concentrations 15 return to 1980 values. In the last third of the 21st century, dependent upon the set of greenhouse gas scenarios used, scenario uncertainty can be the dominant contributor. This result suggests that investment in chemistry-climate modelling is likely to continue to refine projections of stratospheric ozone and estimates of the return of stratospheric ozone concentrations to pre-1980 levels.

    2016-01-01

    Recent advances in biological and computational technologies are changing the way different social groups imagine race, gender, kinship, citizenship and disease risk. Existing taxonomies are being displaced or reconfigured, impacting the ways in which people are governed, how lives are lived, how groups are known and how power is exercised. Herein we report on a two-day international symposium that we co-organized, titled 'The molecularization of identity: science and subjectivity in the 21st century,' that was held on 29-30 April 2016 at the Program on Science, Technology and Society, at Harvard University. The symposium drew upon the tools and expertise from multiple disciplines and diverse geographical regions and consisted of 24 original research presentations and an interdisciplinary roundtable. Specific attention was paid to the bioethical, material and lived dimensions of recent developments in molecular technologies, and discussions interrogated the complex ways in which the 'molecular realm' is an emerging site for constituting human identities in the 21st century. Herein we summarize some of the key findings of the conference and raise three further issues for practitioners and researchers to consider in relation to the broader impact of genetics research. Namely: transnational governance of emerging biotechnologies; representation of different interest groups in policy decisions; and rights of access to emerging technologies. PMID:27376979

    The 21st Century Jobs Initiative has been launched in the context of new realities in Washington, D.C., rapid restructuring of the US economy and accelerating changes in the makeup of the East Tennessee economy driven by these and other external economic forces. Continuing downward pressure on Federal budgets for programs that support three key institutions in the region - DOE`s Oak Ridge complex, the Tennessee Valley Authority and research programs of the University of Tennessee - are especially threatening to the region. With a large part of its economy dependent on Federal spending, the area is at risk of troublesome impacts that could ripple out from the Oak Ridge and Knoxville home of these institutions throughout the entire 15-county {open_quotes}Resource Valley.{close_quotes} As these economic forces play out in the region`s economy, important questions arise. How will East Tennessee {open_quotes}earn its living{close_quotes} in the future if the Federal government role in the economy shrinks? What kind of new industries will be formed to replace those at risk due to Federal cutbacks and economic restructuring? Where will the jobs come from for the next generation of job seekers? These are among the questions driving the 21st Century Jobs Initiative, an action-oriented program designed and implemented by local leaders in response to the economic challenges facing East Tennessee. Fortunately, the region`s economy is strong today. Unemployment is at near record lows in most counties. Moreover, leaders are increasingly aware of the threats on the horizon and are already moving to action. And the impacts from the forces at work on the economy will probably come slowly, over the next decade or so. Based on economic research and input from local leaders knowledgeable about the economy, the 21st Century Jobs Initiative has set forth a strategic economic development plan for the region.

    Full Text Available The paper reviewed the emerging roles of the 21st century librarians, charged with the responsibility to manage repository services across libraries in present-day information technology environment. Librarians need to be trained and empowered with requisite skills and knowledge needed for successful management of the ICT driven repository initiatives that the 21st century demands. Literature was reviewed on the roles and responsibilities of librarians, training needs and opportunities, career path and recruitment of librarians, and community support necessary for effective and efficient implementation and management of repository initiatives. This entails the ability to comprehend trends and change patterns which are essential for providing research focused and user-friendly models in open repository services that are based on thorough analytical understanding of the challenges of emerging trends. To achieve this requires the training and retraining of librarians to reposition them as information specialists in their career path. The role of the library as an integral part of its social environment is to educate the community about the existence of an open repository by building partnership with community-oriented research centres through seminars, workshops, symposium, training, and awareness programmes. The study recommends that librarians should strategize and collaborate with researchers to make open repository an essential research tool.

    Full Text Available This paper focuses on the weaknesses of different democracies of the world in 21st century and suggests some solutions to them. Among the living democracies of the world all of them are not exemplary and among the mediocre ones too all of them are not too bad. Some of the countries are justifying with the splendid principle of democracy and leaving the examples of good governance, self reliance, supremacy of Law and Rule of Equality for the rest of the world. On the other hand some of the countries are still striving hard to establish or retrieve the democracy. We need an ideal of democracy which renders it possible to access to what degree a world government serving a sovereign world parliament could be democratic and independent in order to be prosperous and capable of standing on its own feet in the 21st century. A strong democratic system of government is the only way out for the self reliance and stability of the country. This paper is aimed to identify the problems faced by today’s democratic countries and their solution.

    Gaps between science, technology, engineering, and mathematics (STEM) education and required workplace skills have been identified in industry, academia, and government. Educators acknowledge the need to reform STEM education to better prepare students for their future careers. We pursue this growing interest in the skills needed for STEM disciplines and ask whether frameworks for 21st century skills and engineering education cover all of important STEM competencies. In this study, we identify important STEM competencies and evaluate the relevance of current frameworks applied in education using the standardized job-specific database operated and maintained by the US Department of Labor. Our analysis of the importance of 109 skills, types of knowledge and work activities, revealed 18 skills, seven categories of knowledge, and 27 work activities important for STEM workers. We investigate the perspectives of STEM and non-STEM job incumbents, comparing the importance of each skill, knowledge, and work activity for the two groups. We aimed to condense dimensions of the 52 key areas by categorizing them according to the Katz and Kahn (1978) framework and testing for inter-rater reliability. Our findings show frameworks for 21st century skills and engineering education do not encompass all important STEM competencies. Implications for STEM education programs are discussed, including how they can bridge gaps between education and important workplace competencies.

    n 2012, the National Cancer Institute (NCI) engaged the scientific community to provide a vision for cancer epidemiology in the 21st century. Eight overarching thematic recommendations, with proposed corresponding actions for consideration by funding agencies, professional societies, and the research community emerged from the collective intellectual discourse. The themes are (i) extending the reach of epidemiology beyond discovery and etiologic research to include multilevel analysis, intervention evaluation, implementation, and outcomes research; (ii) transforming the practice of epidemiology by moving toward more access and sharing of protocols, data, metadata, and specimens to foster collaboration, to ensure reproducibility and replication, and accelerate translation; (iii) expanding cohort studies to collect exposure, clinical, and other information across the life course and examining multiple health-related endpoints; (iv) developing and validating reliable methods and technologies to quantify exposures and outcomes on a massive scale, and to assess concomitantly the role of multiple factors in complex diseases; (v) integrating big data science into the practice of epidemiology; (vi) expanding knowledge integration to drive research, policy, and practice; (vii) transforming training of 21st century epidemiologists to address interdisciplinary and translational research; and (viii) optimizing the use of resources and infrastructure for epidemiologic studies. These recommendations can transform cancer epidemiology and the field of epidemiology, in general, by enhancing transparency, interdisciplinary collaboration, and strategic applications of new technologies. They should lay a strong scientific foundation for accelerated translation of scientific discoveries into individual and population health benefits.

    Indian leadership has been crucial in both the establishment of the foundational capabilities of the Power Partnership as well as the realization of opportunities for applied policy implementation. Understanding policy regimes that support and accelerate the transition to clean, smart, efficient, affordable, and reliable electricity will help inform decisions that enable innovative solutions, or even disruptive innovations. India has already demonstrated a wide variety of business model innovation in a wide range of industries. Its potential to do the same in the power sector is an enormous opportunity. Indian contributions to international knowledge about the legal, regulatory and business environment will be an integral component of the Power Partnership program.

    We report here a review of the seventh mitochondrial DNA (mtDNA) exercise undertaken by the Spanish and Portuguese working group (GEP) of the International Society for Forensic Genetics (ISFG) corresponding to the period 2003-2004. Five reference bloodstains from five donors (M1-M5), a mixed stain of saliva and semen (M6), and a hair sample (M7) were submitted to each participating laboratory for nuclear DNA (nDNA; autosomal STR and Y-STR) and mtDNA analysis. Laboratories were asked to investigate the contributors of samples M6 and M7 among the reference donors (M1-M5). A total of 34 laboratories reported total or partial mtDNA sequence data from both, the reference bloodstains (M1-M5) and the hair sample (M7) concluding a match between mtDNA profiles of M5 and M7. Autosomal STR and Y-STR profiling was the preferred strategy to investigate the contributors of the semen/saliva mixture (M6). Nuclear DNA profiles were consistent with a mixture of saliva from the donor (female) of M4 and semen from donor M5, being the semen (XY) profile the dominant component of the mixture. Strikingly, and in contradiction to the nuclear DNA analysis, mtDNA sequencing results yield a more simple result: only the saliva contribution (M4) was detected, either after preferential lysis or after complete DNA digestion. Some labs provided with several explanations for this finding and carried out additional experiments to explain this apparent contradictory result. The results pointed to the existence of different relative amounts of nuclear and mtDNAs in saliva and semen. We conclude that this circumstance could strongly influence the interpretation of the mtDNA evidence in unbalanced mixtures and in consequence lead to false exclusions. During the GEP-ISFG annual conference a validation study was planned to progress in the interpretation of mtDNA from different mixtures.

    Currently there is a call for brief concise measurements to appraise relevant 21st century college readiness skills in K-12 learners. This study employed K-12 teachers' ratings for over 3,000 students for an existing 91-item rating scale, the Human Behavior Rating Scale, that measured the 21st century skills of persistence, curiosity, externalizing affect, internalizing affect, and cognition. Teachers' ratings for K-12 learners were used to develop a brief, concise, and manageable 30-item tool, the Human Behavior Rating Scale-Brief. Results yielded high internal consistency coefficients and inter-item correlations. The items were not biased with regard to student sex or race, and were supported through confirmatory factor analyses. In addition, when teachers' ratings were compared with students' academic and behavioral performance data, moderate to strong relationships were revealed. This study provided an essential first step in the development of a psychometrically sound, manageable, and brief tool to appraise 21st century skills in K-12 learners.

    Full Text Available In his book Humanitarian Intervention and Legitimacy Wars: Seeking Peace and Justice in the 21st Century, Richard Falk argues that, with the growing prevalence of soft power, historical lessons of asymmetric warfare and legitimacy wars must be taken into account. Falk rejects the realist notion that the state is the only rational actor, offering a more constructivist approach that focuses on the norms, culture and morality of the international community. He asserts that humanitarian intervention is on the decline, and legitimacy wars are increasing. Much of this legitimacy is based on international law and its relevance in the international community.

    Yanji is the biggest China Korean inhabited city. Based on a newly finished research project, this paper discusses strategic problems about Yanji towards 21st century. The general point of the authors is that at the beginning of new century,Yanji will play a more important role in Tumen River Delta development, regional economy cooperation in Korea Peninsula as well as Northeast Asia, and it will develop to be an important central city in this area. This paper puts forwards Yanji City′s developing goal, urban nature, and urban size, probes its regional orientation, and further probes how to establish The Yanji Urban Economy Cooperation Zone. The authors think that Yanji should depend on its intellect resources and other characteristic resources. Industry development need to pay much attention to modern agriculture, tertiary industry (especially commerce, trade and tourism) and dominant industries, and high-tech industry must give a special care, in order to establish a light industrial structure.

    Space medicine research in the 21st century will continue to focus on the four major areas including: (1) expansion of the current incomplete knowledge base of clinical and subclinical physiological changes due to microgravity; (2) development of countermeasures to extend the capabilities of the human performance envelope in extended duration flights; (3) development of novel methods for delivering all aspects of a comprehensive health care system in extreme remote conditions: and (4) further research and application of systems for biological materials processing. New space transportation vehicles will place unique physiologic and human factors demands on the human system, while providing better access to platforms for materials processing. Success in meeting the demands in each of the noted research areas will require an extensive, interactive team approach. Personnel from the medical research,operational, developmental, and basic science communities will be essential to success.

The current mode of our democratic system is archaic in addressing the world’s multifaceted global crises. So, there’s a dire need to incorporate new elements of democratic governance to address the issue. Humanity now lives in a transition period, so the path may not be easy. But the scientific and technological revolution underway is rapidly changing the mindsets of people and helping them exercise their rights. The article thus focuses on how democracy serves as the best system to ensure human rights and provide for a better society and also, how current models of democratic governance which matured in the last century can be improved in the 21st century, which is instrumental for meeting the challenges humanity confronts today. – Editor

  3. Coal research strategies for the 21st century

    International Nuclear Information System (INIS)

    This paper provides a personal view of the research strategies which will be necessary to develop the new generations of equipment and new concepts and processes which will be required by the coal industry into the 21st century. It is claimed that the economics of coal supply and availability will continue to ensure that coal retains a very significant role as long as it is not targeted by taxes, regulation or penalties which are specifically intended to take it out of contention. In the author opinion, the coal industry needs to show that coal can be produced safely and with acceptable environmental impacts for future land use. These issues of community concern impact on all coal mining companies, and the need is a common one to maintain industry wide collaborative support for research to provide the technological innovation which will be an essential part of their solutions

  4. Infection imaging with radiopharmaceuticals in the 21st century

    International Nuclear Information System (INIS)

    Infection continues to be a major cause of morbidity and mortality worldwide. Nuclear medicine has an important role in aiding the diagnosis of particularly deep-seated infections such as abscesses, osteomyelitis, septic arthritis, endocarditis, and infections of prosthetic devices. Established techniques such as radiolabelled leucocytes are sensitive and specific for inflammation but do not distinguish between infective and non-infective inflammation. The challenge for Nuclear Medicine in infection imaging in the 21st century is to build on the recent trend towards the development of more infection specific radiopharmaceuticals, such as radiolabelled anti-infectives (e.g. 99 m Tc ciprofloxacin). In addition to aiding early diagnosis of infection, through serial imaging these agents might prove very useful in monitoring the response to and determining the optimum duration of anti-infective therapy. This article reviews the current approach to infection imaging with radiopharmaceuticals nd the future direction it might take. (author)

  5. Heat stress and societal impacts in the 21st century

    Heat is the number-one weather related killer in the US and around the world. As a result of rising temperatures and steady or slightly rising levels of specific humidity, heat stress is projected to become increasingly severe. Here we show that heat stress as measured by two common indices -- the heat index and the wet-bulb temperature -- is projected to rapidly and dramatically increase, and that by mid-century crippling summertime conditions are possible across some of the most densely populated regions of the planet. Many of these regions are places where cooling infrastructure is scarce, adaptive capacity is low, and populations are rapidly rising. We find that by the end of the 21st century, the habitability of some regions of the planet may be questionable due to heat stress alone, and in many other regions severe impacts to human health, infrastructure, agriculture, and economic performance will create significant societal stress and necessitate rapid adaptation.

  6. Challenges for Educational Technologists in the 21st Century

    2015-09-01

    Full Text Available In 1972, Edsger Dijkstra claimed that computers had only introduced the new problem of learning to use them effectively. This is especially true in 2015 with regard to powerful new educational technologies. This article describes the challenges that 21st century educational technologists are, and will be, addressing as they undertake the effective integration of new technologies into K-12 educational systems and learning environments. The expanding Internet, ever more powerful mobile devices, and other innovations make the task of designing effective formal and informal learning challenging, especially in light of the high rate of change in these new technologies. While these technologies introduce many benefits, they are also causing serious threats to system security and personal privacy. Furthermore, as these technologies continue to evolve, ethical issues such as equal access to resources become imperative. Educational technologists must expand their forward-thinking leadership and planning competencies so as to ensure effective use of new technologies.

    2011-05-01

    This paper identifies the contribution of health and clinical informatics in the support of healthcare in the 21st century. Although little is known about the health and clinical informatics workforce, there is widespread recognition that the health informatics workforce will require significant expansion to support national eHealth work agendas. Workforce issues including discipline definition and self-identification, formal professionalisation, weaknesses in training and education, multidisciplinarity and interprofessional tensions, career structure, managerial support, and financial allocation play a critical role in facilitating or hindering the development of a workforce that is capable of realising the benefits to be gained from eHealth in general and clinical informatics in particular. As well as the national coordination of higher level policies, local support of training and allocation of sufficient position hours in appropriately defined roles by executive and clinical managers is essential to develop the health and clinical informatics workforce and achieve the anticipated results from evolving eHealth initiatives.

    1996-01-01

    Space Technology has been rapidly increasing in the past decade. This can be attributed to the future construction of the International Space Station (ISS). New innovations must constantly be engineered to make ISS the safest, quality, research facility in space. Since space science must often be gathered by crew members, more attention must be geared to the human's safety and comfort. Virtual simulations are now being used to design environments that crew members can live in for long periods of time without harmful effects to their bodies. This paper gives a few examples of the ergonomic design problems that arise on manned space flights, and design solutions that follow NASA's strategic commitment to customer satisfaction. The conclusions show that virtual simulations are a great asset to 21st century design.

    An International Conference entitled "Close Binaries in the 21st Century: New Opportunities and Challenges", was held in Syros island, Greece, from 27 to 30 June, 2005. There are many binary star systems whose components are so close together, that they interact in various ways. Stars in such systems do not pass through all stages of their evolution independently of each other; in fact their evolutionary path is significantly affected by their companions. Processes of interaction include gravitational effects, mutual irradiation, mass exchange, mass loss from the system, phenomena of extended atmospheres, semi-transparent atmospheric clouds, variable thickness disks and gas streams. The zoo of Close Binary Systems includes: Close Eclipsing Binaries (Detached, Semi-detached, Contact), High and Low-Mass X-ray Binaries, Cataclysmic Variables, RS CVn systems, Pulsar Binaries and Symbiotic Stars. The study of these binaries triggered the development of new branches of astrophysics dealing with the structure and ev...

  7. World energy strategies into the 21st century

    International Nuclear Information System (INIS)

    In mid-1990s, tighter oil supply and firmer and higher price will be projected due to the declining production in non-OPEC countries. The OPEC members have the oil production capacity of 30 million barrels a day, but last year, OPEC produced 17 million barrels a day. World oil demand was down about 600,000 barrels a day due primarily to the continued substitution with natural gas, coal and nuclear power. The conclusion of the UK coal strike also contributed to the drop of the demand for residual fuel oil. Economic growth was too sluggish to offset the substitution effect. The crude oil production from non-OPEC sources has increased, but low price will reverse the trend of non-OPEC production. Energy supply will be ample to meet the projected demand through the next decade. The annual growth rate of less than 2 % was forecast for the primary energy demand in non-communist world, assuming the economic growth of 3 % a year worldwide. The trend of the use of natural gas, coal and nuclear power is discussed. At the beginning of the 21st century, world energy will be supplied 42 % by oil, 18 % by natural gas, 24 % by coal and 8 % by nuclear power. (Kako, I.)

    2005-01-01

    The 21st century is referred to as a "century for cities" or "era for cities" and China has also speeded up its process of urbanization. It is very important to choose a scientific urbanization pattern to exert the function of cities and realize our dream for China to become a powerful modernized country.It's concluded from history since 1800 that the pattern of the world urbanization has transformed from "extensive" to "intensive". However, it is still an extensive pattern in China, and there are many problems behind the splendid achievements, reflected on the urbanization process of our country since 1949. Today, sustainable development and the knowledge economy are the themes of the cities; it is inevitable to change our urbanization pattern.Based on the dialectic relationship of quality and quantity, the article points out that urbanization should not only focus on quantity but also on quality in China. High quality and multiform urbanization pattern is an inevitable choice of China, and the development of the region can also be exalted by the radiation of the cities. But what's the real meaning of the new pattern? What's its difference from the western countries'? The article discusses its content according to the reality of China.

    The aim of this article is to bring forward and realise the size of cardiovascular diseases and the burden of its numbers that concern practising doctors in Lower Silesia, in Poland, Europe and the world. Every fourth patient knocking at the GP's door comes with a problem with the circulatory system. These diseases are the reason for every second in hospitalization or referral to a specialist. The most common diagnosis is not the common cold but arterial hypertension. Three of the most common diseases in patients over 65 years old are: hypertension, ischaemic heart disease, and atherosclerosis of the brain arteries. Poland belongs to the group of developed countries with an emerging economy, where degenerative diseases dominate, and cardiovascular diseases account for the biggest problems within the Health System. Nearly half of male deaths (46%) and over half of female deaths (56%) are the consequence of cardiovascular diseases. 80% of people around the world live in developing economies, where cardiovascular diseases cause 23% of all deaths. Every fifth person lives in a developed country and has a 50% chance of dying because of cardiovascular diseases. Will these diseases become "the number one killer" of the 21st century? 27% lost healthy life years are due to arterial hypertension, ischeamic heart disease, and congestive heart failure so their epidemiology is being regarded in this article.

    2015-01-01

    This study examined bullying and cyberbullying prevalence among 367 adolescents 10 to 18 years of age who were attending schools and community organizations in suburban and urban neighborhoods in the Midwest United States. The correlational design investigated adolescents' daily use of technology that could be used to cyberbully peers, such as cell phones, computers, email, and the Internet. Results showed that 30% of participants had been bullied during school, and 17% had been cyberbullied, with online social networking sites the most common media employed (68%). The majority of participants owned or had access to computers (92%), email accounts (88%), social networking accounts (e.g., Facebook or MySpace) (82%), and cell phones (79%). Daily technology use included an average of two hours on a computer and a median of 71 text messages per day. Logistic regression analysis revealed no significant differences in bullying or cyberbullying prevalence based on location (urban or suburban) or demographic characteristics. Given the substantial presence of cyberbullying and the increase in technology use among adolescents in the 21st century, nurses need knowledge of the phenomenon to plan assessments in clinical practice. Early identification and assessment of cyberbullying victims and perpetrators, and development and implementation of effective interventions are needed to reduce this form of bullying among adolescents.

    2016-02-01

    Full Text Available The paper examines young adult dystopian novels written in the first decade of the 21st century, as heirs to the tradition of the bildungsroman, and the great dystopias. The focus of this new genre has shifted from maintaining "the best of all worlds" – where the young person adjusts and fits into the existing world, to the shaping of the hero’s critical spirit which is supposed to result in the hero/heroine growing up, but also in changes in the world which they inhabit. Two other important characteristics of these novels are the critical relationship toward ancestors and tradition on the one hand, and on the other the positive assessment of non-rational decisions which are made impulsively and are based on emotions, which points to the abandonment of different aspects of the heritage of modernity (the traditions of rationalism and romanticism. Thus they set the stage for a new, different view of the world and the role which the individual is to fulfill by growing from a child into an adult in such a world.

    Full Text Available One of the five primary objectives of the European Union within the framework of Europe 2020 is to increase the proportion of the tertiary educated population. The research task titled “The motivation of the student in the 21st century” is intended to address the factors that have both an impact on the decision of students to pursue higher studies and affect the choice of a specific field of study and a preferred form of study. The stimulus to the exploration was sparked by the mentioned EU initiative, interesting statistical data, the growing number of students studying in the external form compared to the daily option, and an increase of students from abroad. Therefore, it is necessary to identify the causes of these trends. Motivation of students is not researched in a systematic way in Slovakia, even though it is an important factor in a student’s decisionmaking process to study. Information was obtained by a questionnaire distributed to 105 students, evaluated using SPSS software and application of descriptive statistics.

  14. Civilian Power from Space in the Early 21st Century

    Energy Technology Data Exchange (ETDEWEB)

    Hyde, R; Ishikawa, M; Wood, L

    2003-06-01

    If power beamed from space is to be become widely used on Earth in the first half of the 21St century, several thus-far-persistent impediments must be obviated, including threshold effects and problematic aspects of cost, availability, reliability, hazards and environmental impacts. We sketch a generally-applicable route to doing so, noting key enabling technologies and practical features. Likely-essential features of any successful strategy include vigorous, systematic leveraging of all intrinsic features of space-derived power, e.g., addressing marginal, high-value-added markets for electric power in space- and time-agile manners to conveniently provide power-upon-demand, and incrementally ''wedging'' into ever-larger markets with ever more cost-efficient generations and scales of technology. We suggest that no prudent strategic plan will rely upon large-scale, long-term public subsidies--fiscal, regulatory, etc.--with their attendant ''sovereign risks'' and interminable delays, and that plan-essential governmental support likely will be limited to early feasibility demonstrations, provision of threshold technologies and a rational, competition-neutral licensing environment. If salient realities are uniformly respected and accessible technologies are intelligently leveraged, electricity derived from space-sourced power-beams may come into significant civilian use during the latter part of the first quarter of this century, and may become widely used by the half-century point.

    2008-10-01

    Estimates of 21st Century global-mean surface temperature increase have generally been based on scenarios that do not include climate policies. Newly developed multigas mitigation scenarios, based on a wide range of modeling approaches and socioeconomic assumptions, now allow the assessment of possible impacts of climate policies on projected warming ranges. This article assesses the atmospheric CO(2) concentrations, radiative forcing, and temperature increase for these new scenarios using two reduced-complexity climate models. These scenarios result in temperature increase of 0.5-4.4 degrees C over 1990 levels or 0.3-3.4 degrees C less than the no-policy cases. The range results from differences in the assumed stringency of climate policy and uncertainty in our understanding of the climate system. Notably, an average minimum warming of approximately 1.4 degrees C (with a full range of 0.5-2.8 degrees C) remains for even the most stringent stabilization scenarios analyzed here. This value is substantially above previously estimated committed warming based on climate system inertia alone. The results show that, although ambitious mitigation efforts can significantly reduce global warming, adaptation measures will be needed in addition to mitigation to reduce the impact of the residual warming.

    The 1960's-era National Committee for Fluid Mechanics Films produced 39 famous 16mm films - dated but still in use - with 3 million dollars of NSF funding. Here we examine the nature of new fluid mechanics films, goals, media changes, and practicality. Examples are given of new narrated videos produced to illustrate chapters of a basic fluids text and provide a ``glimpse through the laboratory window.'' Both experiments and CFD are featured, though the facilities needed for the former are declining. The fundamentally-visual nature of the topic is emphasized with no repetition of text or equations. We believe this visual nature of fluid mechanics is the key to its role in renewed efforts to bolster US science education. This is one - not the only - paradigm for new fluid mechanics films. While inflation makes such film production perhaps 6 times more expensive than in the 1960's, there are offsetting economies based on consumer video technology and digital desktop production. Nonetheless, funding new educational fluid mechanics videos in the 21st century remains a daunting prospect.

  17. Biosurfactants: Multifunctional Biomolecules of the 21st Century

    Full Text Available In the era of global industrialisation, the exploration of natural resources has served as a source of experimentation for science and advanced technologies, giving rise to the manufacturing of products with high aggregate value in the world market, such as biosurfactants. Biosurfactants are amphiphilic microbial molecules with hydrophilic and hydrophobic moieties that partition at liquid/liquid, liquid/gas or liquid/solid interfaces. Such characteristics allow these biomolecules to play a key role in emulsification, foam formation, detergency and dispersal, which are desirable qualities in different industries. Biosurfactant production is considered one of the key technologies for development in the 21st century. Besides exerting a strong positive impact on the main global problems, biosurfactant production has considerable importance to the implantation of sustainable industrial processes, such as the use of renewable resources and “green” products. Biodegradability and low toxicity have led to the intensification of scientific studies on a wide range of industrial applications for biosurfactants in the field of bioremediation as well as the petroleum, food processing, health, chemical, agricultural and cosmetic industries. In this paper, we offer an extensive review regarding knowledge accumulated over the years and advances achieved in the incorporation of biomolecules in different industries.

  18. Being Black and Brown in the 21st Century

    Full Text Available Depending on one’s level of understanding and awareness about the plight of Black and Brown people, one might argue that they are better off today than they were 50 years ago or so, especially when one remembers the Jim Crow era during which Black and Brown people were ruthlessly brutalized, particularly by White supremacist groups such as the Klu Klux Kan. However, if one critically analyzed the achievement gap between students of color and their White counterparts, the decline in incomes, and other forms of educational and socioeconomic inequality that Black and Brown people, particularly poor students of color, have been experiencing for the last several decades or so, one would realize that substantially nothing has changed for them. In light of this view, this article explores the educational and socioeconomic conditions of People of Color, including those of linguistically and culturally diverse students. Specifically, it examines the ways and the degree to which lack of resources combined with institutional racism and the legacy of slavery continue to limit the life chances of Black and Brown people in the 21st century. The author ends this article making recommendations to counter inequality in schools and society at large that Black and Brown people have been facing.

    A strategic approach for retaining and more efficiently operating the essential Langley Ground Testing Facilities in the 21st Century is presented. This effort takes advantage of the previously completed and ongoing studies at the Agency and National levels. This integrated approach takes into consideration the overall decline in test business base within the nation and reduced utilization in each of the Langley facilities with capabilities to test in the subsonic, transonic, supersonic, and hypersonic speed regimes. The strategy accounts for capability needs to meet the Agency programmatic requirements and strategic goals and to execute test activities in the most efficient and flexible facility operating structure. The structure currently being implemented at Langley offers agility to right-size our capability and capacity from a national perspective, to accommodate the dynamic nature of the testing needs, and will address the influence of existing and emerging analytical tools for design. The paradigm for testing in the retained facilities is to efficiently and reliably provide more accurate and high-quality test results at an affordable cost to support design information needs for flight regimes where the computational capability is not adequate and to verify and validate the existing and emerging computational tools. Each of the above goals are planned to be achieved, keeping in mind the increasing small industry customer base engaged in developing unpiloted aerial vehicles and commercial space transportation systems.

  20. Flue gas cleaning by electron beam technology in 21st

    International Nuclear Information System (INIS)

    China is paying great attention to the pollution caused by flue gases including sulfur oxides, nitrogen oxides, fine particles, and volatile organic compounds (VOC) for the environmental protection and sustainable development of China economy for 21st century. Among several promising processes, applicable to industrial scale, the electron beam (EB) scrubbing process can simultaneously remove SO2, NOx, PM-10 (particulate matter 10 μm or less in diameter), VOC and CO2 from the flue gas is a new high technology combined with radiation chemistry and electron accelerator technique. The EB flue gas purification process consists of the producing ionization in the EB irradiated gases followed by the formation of free radicals and active species which ultimately forming foggy sulfur acid and nitrate acid. These acids react further with added ammonia to form ammonium sulfate and nitrates as by-products, which can be fertilizer usable in agriculture. The next stage for this technology is its optimization for the reduction of electricity energy consumption and an effective collection of by-products. Lastly the investment cost for EB method is shown to be the most economic compared with other competing methods. (S. Ohno)

    The South Asian site in the INTERGROWTH-21(st) Project was the city of Nagpur, in Maharashtra State, India, with approximately 4500 births per year among the target population with middle to high socio-economic status. These deliveries are mainly concentrated in 20 small private hospitals, most of which are in the city centre. The sample for the Newborn Cross-Sectional Study (NCSS) was drawn from ten of these hospitals, covering 76% of the target low-risk pregnant population. The Fetal Growth Longitudinal Study (FGLS) sample was recruited from the largest of these institutions, Ketkar Hospital, as well as several ancillary antenatal care clinics. Special activities to encourage participation and raise awareness of the study at this site included translating patient information leaflets into local languages and securing local media interest. Among the unique challenges of the Indian site was the coordination of the large number of hospitals involved in NCSS, a task that required careful planning and organisation by the field teams.

  3. Bionic autonomic neuromodulation revolutionizes cardiology in the 21st century.

    2009-01-01

    In this invited session, we would like to address the impact of bionic neuromodulation on cardiovascular diseases. It has been well established that cardiovascular dysregulation plays major roles in the pathogenesis of cardiovascular diseases. This is the reason why most drugs currently used in cardiology have significant pharmacological effects on the cardiovascular regulatory system. Since the ultimate center for cardiovascular regulation is the brainstem, it is conceivable that autonomic neuromodulation would have significant impacts on cardiovascular diseases. On the basis of this framework, we first developed a bionic, neurally regulated artificial pacemaker. We then substituted the brainstem by CPU and developed a bionic artificial baroreflex system. We further developed a bionic brain that achieved better regulatory conditions than the native brainstem in order to improve survival in animal model with heart failure. We recently developed a bionic neuromodulation system to reduce infarction size following acute myocardial infarction. We believe that the bionic neuromodulation will inspire even more intricate applications in cardiology in the 21(st) century.

    Full Text Available Although tumors on the surface of the skin are considered to be easily recognizable, neglected advanced skin neoplasms are encountered even in the 21st century. There can be numerous causes of the delay in the diagnosis: fear of the diagnosis and the treatment, becoming accustomed to a slowly growing tumor, old age, a low social milieu, and an inadequate hygienic culture are among the factors leading some people not to seek medical advice. The treatment of such advanced neoplasms is usually challenging. The therapy of neglected cases demands an individual multidisciplinary approach and teamwork. Basal cell carcinoma (BCC, the most common cutaneous tumor, usually develops in the elderly, grows slowly, and has an extremely low metastatic potential; these factors are suggesting that BCCs might well be the “ideal candidates” for neglected tumors. Five neglected advanced cases of BCC were diagnosed in our dermatological institute between 2000 and 2009. The clinical characteristics and treatment modalities of these neoplasms are discussed, together with the possible causes of the neglect.

    2015-01-01

    The form of the public health system in India is a three tiered pyramid-like structure consisting primary, secondary, and tertiary healthcare services. The content of India's health system is mono-cultural and based on western bio-medicine. Authors discuss need for health sector reforms in the wake of the fact that despite huge investment, the public health system is not delivering. Today, 70% of the population pays out of pocket for even primary healthcare. Innovation is the need of the hour. The Indian government has recognized eight systems of healthcare viz., Allopathy, Ayurveda, Siddha, Swa-rigpa, Unani, Naturopathy, Homeopathy, and Yoga. Allopathy receives 97% of the national health budget, and 3% is divided amongst the remaining seven systems. At present, skewed funding and poor integration denies the public of advantage of synergy and innovations arising out of the richness of India's Medical Heritage. Health seeking behavior studies reveal that 40-70% of the population exercise pluralistic choices and seek health services for different needs, from different systems. For emergency and surgery, Allopathy is the first choice but for chronic and common ailments and for prevention and wellness help from the other seven systems is sought. Integrative healthcare appears to be the future framework for healthcare in the 21(st) century. A long-term strategy involving radical changes in medical education, research, clinical practice, public health and the legal and regulatory framework is needed, to innovate India's public health system and make it both integrative and participatory. India can be a world leader in the new emerging field of "integrative healthcare" because we have over the last century or so assimilated and achieved a reasonable degree of competence in bio-medical and life sciences and we possess an incredibly rich and varied medical heritage of our own.

    2010-01-01

    In the second half of the 20th century it became obvious that a relentless increase in diabetes type 2 (DM) affecting the economically affluent countries, is gradually afflicting also the developing world. This review juxtaposes the threat that the DM epidemic represents to mankind, with the astonishing recent discoveries on the role of obesity and of the body fat in this metabolic disorder. Presently, the highest prevalence of DM is in Saudi Arabia, a country deep in riches generated by its oil wells. DM is very high, in over 10% of adults in the USA, Switzerland and Austria. Prevalence is low in Norway, China and in Iceland. Predictions of epidemiologists for the first third of the 21st century claim up to 2.5 times increase in DM in the Middle East, Sub-Saharan Africa, India, rest of Asia and in the Latin America. In China the number of patients with DM will double but in the economically advanced countries that experienced rise in DM in the 20th century, the increase will be only about 50%. Remarkably, a lowest increase in DM is expected in the countries that formerly belonged to the Soviet political space. Increasing urbanization, aging populations, obesity, and falling levels of physical activity are all contributing to the rise of DM worldwide. The main cause of DM pandemic is growing prevalence of obesity, in Europe and in the Latin America. In the North America obesity is considered to be responsible for 90% of DM in females. Male obesity is associated with DM slightly less, at 70-80% in the European Union and in the US. The precise mechanism by which obesity leads to insulin resistance and to DM is not completely described but it may be related to several biochemical factors, such as abnormalities in free fatty acids, adipokines, leptin and other substances (Tab. 1, Fig. 4, Ref. 24).

  9. Maunder's Butterfly Diagram in the 21st Century

    2005-01-01

    E. Walter Maunder created his first "Butterfly Diagram" showing the equatorward drift of the sunspot latitudes over the course of each of two solar cycles in 1903. This diagram was constructed from data obtained through the Royal Greenwich Observatory (RGO) starting in 1874. The RGO continued to acquire data up until 1976. Fortunately, the US Air Force (USAF) and the US National Oceanic and Atmospheric Administration (NOAA) have continued to acquire similar data since that time. This combined RGO/USAF/NOAA dataset on sunspot group positions and areas now extends virtually unbroken from the 19th century to the 21st century. The data represented in the Butterfly Diagram contain a wealth of information about solar activity and the solar cycle. Solar activity (as represented by the sunspots) appears at mid-latitudes at the start of each cycle. The bands of activity spread in each hemisphere and then drift toward the equator as the cycle progresses. Although the equator itself tends to be avoided, the spread of activity reaches the equator at about the time of cycle maximum. The cycles overlap at minimum with old cycle spots appearing near the equator while new cycle spots emerge in the mid-latitudes. Large amplitude cycles tend to have activity starting at higher latitudes with the activity spreading to higher latitudes as well. Large amplitude cycles also tend to be preceded by earlier cycles with faster drift rates. These drift rates may be tied to the Sun s meridional circulation - a component in many dynamo theories for the origin of the sunspot cycle. The Butterfly Diagram must be reproduced in any successful dynamo model for the Sun.

  10. Public support for nuclear energy in the 21st century

    International Nuclear Information System (INIS)

    Public support for nuclear energy in the next millennium will depend on the extent to which two essential qualities are exercised now by industry and governments. These qualities are leadership and vision. However, a fear of leadership in supporting nuclear energy afflicts government officials and legislators and many industry stakeholders as well. The paper examines a root cause of this fear of leadership, namely the use of an incomplete and outdated model of public opinion on nuclear energy. The old model leads to the conclusion that expressing support for nuclear energy is politically risky. Yet a new, more complete, model of public opinion on nuclear energy is readily available from the social science research. By underestimating various types of support that exist, the old model causes stakeholders in the industry to believe that their position is unpopular. This may make them reluctant to lead the way in speaking out. Thus, politicians and government officials hear most from a small opposition. Leadership in speaking out and advocating solutions is not sufficient for assuring public support for nuclear energy in the 21st century. Under the umbrella of sustainable development, opinion leaders worldwide are assessing energy sources on the basis of ethical and environmental considerations, not just economics. Leaders in the nuclear industry for years have made a strong case for nuclear energy as a moral imperative, based on the absence of emissions and the preservation of natural resources. This case can and must be developed through active participation in world movements, by listening to all views, and by helping to define what is sustainable and just for future generations. (author)

    Full Text Available Rheumatoid arthritis (RA, juvenile arthritis, spondyloarthritis, including psoriatic arthritis, systemic lupus erythematosus (SLE, and other systemic connective tissue diseases, are the most severe chronic immunoinflammatory rheumatic diseases (IIRDs that affect as high as 10% of the population. Substantial progress has been made in the treatment of IIRDs in the 21st century. The current Treat to Target (T2T strategy for RA is to achieve remission as soon as possible. The main treatment goal is to improve quality of life, by controlling the symptoms of the disease, by preventing joint destruction and dysfunction, and by maintaining social possibilities. The most important way to achieve this goal is to inhibit inflammation and to evaluate the efficiency of treatment, by using the standardized activity indices and by choosing the appropriate treatment option. The widespread use of biological agents in combination with standard disease-modifying antirheumatic drugs could substantially enhance therapeutic effectiveness. A new class of medicaments (chemically synthesized small molecular weight agents to treat RA has appeared. The point of their application is tyrosine kinases, primarily Janus kinase (JAK. The new era in the treatment of SLE and other IIRDs is associated with the design of the new class of drugs Р BLyS inhibitors. In the coming years, the main lines of researches by Russian rheumatologists will be to elaborate a strategy to prevent IIRDs; to introduce innovative methods for their early diagnosis and treatment (biological agents, JAK inhibitors, and other cell signaling molecules and for the prediction of the outcomes of the most severe forms of IIRD; to realize the concept of personified medicine (to investigate the prognostic biomarkers of the efficiency and safety of targeted therapy, to reduce the risk of infectious complications, cardiovascular diseases, cancer, osteoporotic fractures, and other comorbidities.

  14. The INTERGROWTH-21st Project Neurodevelopment Package: a novel method for the multi-dimensional assessment of neurodevelopment in pre-school age children.

    Directory of Open Access Journals (Sweden)

    Michelle Fernandes

    Full Text Available BACKGROUND: The International Fetal and Newborn Growth Consortium for the 21st Century (INTERGROWTH-21st Project is a population-based, longitudinal study describing early growth and development in an optimally healthy cohort of 4607 mothers and newborns. At 24 months, children are assessed for neurodevelopmental outcomes with the INTERGROWTH-21st Neurodevelopment Package. This paper describes neurodevelopment tools for preschoolers and the systematic approach leading to the development of the Package. METHODS: An advisory panel shortlisted project-specific criteria (such as multi-dimensional assessments and suitability for international populations to be fulfilled by a neurodevelopment instrument. A literature review of well-established tools for preschoolers revealed 47 candidates, none of which fulfilled all the project's criteria. A multi-dimensional assessment was, therefore, compiled using a package-based approach by: (i categorizing desired outcomes into domains, (ii devising domain-specific criteria for tool selection, and (iii selecting the most appropriate measure for each domain. RESULTS: The Package measures vision (Cardiff tests; cortical auditory processing (auditory evoked potentials to a novelty oddball paradigm; and cognition, language skills, behavior, motor skills and attention (the INTERGROWTH-21st Neurodevelopment Assessment in 35-45 minutes. Sleep-wake patterns (actigraphy are also assessed. Tablet-based applications with integrated quality checks and automated, wireless electroencephalography make the Package easy to administer in the field by non-specialist staff. The Package is in use in Brazil, India, Italy, Kenya and the United Kingdom. CONCLUSIONS: The INTERGROWTH-21st Neurodevelopment Package is a multi-dimensional instrument measuring early child development (ECD. Its developmental approach may be useful to those involved in large-scale ECD research and surveillance efforts.

    Throughout history, peasant farming has proved remarkably resilient to the forces of free-market capitalism both in Europe and Internationally. However, in many countries there are declining numbers of small scale famers, and an increase in larger conventional farms (due to international and national policies). There is an urgent need to renormalise and celebrate the resilience and adaptability of the peasant farming model, and look at how it can be adapted into our 21st century societies.

    During the 21st Century, space activity will have a profound influence on life on Earth and on the development of society. Space activity will touch ever more firmly on the provision of the necessities and qualities of life and will accelerate the movement of nations towards the concept of the global village. A study by Prospective 2100, a group identifying major global trends for the next century, ranked space activity as one of the twelve most important factors for shaping the next century, alongside such items as education, ocean cities, the planetary garden, caring and sharing. The International Space University, ISU, the International Astronautical Federation, IAF, and Prospective 2100 joined forces to study in detail how this influence of space activity would be manifested in the next century. The one-day forum at UNISPACE III was one of a number of international, intercultural and interdisciplinary fora held during the past year to consider what would be the most appropriate space activity for the next century to meet the needs of humanity. The findings and recommendations of the forum are presented in this report.

    2001-01-01

    Full Text Available The scientific problems posed by the Earth's fluid envelope, and its atmosphere, oceans, and the land surface that interacts with them are central to major socio-economic and political concerns as we move into the 21st century. It is natural, therefore, that a certain impatience should prevail in attempting to solve these problems. The point of this review paper is that one should proceed with all diligence, but not excessive haste: "festina lente," as the Romans said two thousand years ago, i.e. "hurry in a measured way." The paper traces the necessary progress through the solutions to the ten problems: 1. What is the coarse-grained structure of low-frequency atmospheric variability, and what is the connection between its episodic and oscillatory description? 2. What can we predict beyond one week, for how long, and by what methods? 3. What are the respective roles of intrinsic ocean variability, coupled ocean-atmosphere modes, and atmospheric forcing in seasonal-to-interannual variability? 4. What are the implications of the answer to the previous problem for climate prediction on this time scale? 5. How does the oceans' thermohaline circulation change on interdecadal and longer time scales, and what is the role of the atmosphere and sea ice in such changes? 6. What is the role of chemical cycles and biological changes in affecting climate on slow time scales, and how are they affected, in turn, by climate variations? 7. Does the answer to the question above give us some trigger points for climate control? 8. What can we learn about these problems from the atmospheres and oceans of other planets and their satellites? 9. Given the answer to the questions so far, what is the role of humans in modifying the climate? 10. Can we achieve enlightened climate control of our planet by the end of the century? A unified framework is proposed to deal with these problems in succession, from the shortest to the longest timescale, i.e. from weeks to

    The ocean is a substantial source of nitrous oxide (N2O) to the atmosphere, but little is known on how this flux might change in the future. Here, we investigate the potential evolution of marine N2O emissions in the 21st century in response to anthropogenic climate change using the global ocean biogeochemical model NEMO-PISCES. We implemented two different parameterizations of N2O production, which differ primarily at low oxygen (O2) conditions. When forced with output from a climate model simulation run under the business-as-usual high CO2 concentration scenario (RCP8.5), our simulations suggest a decrease of 4 to 12% in N2O emissions from 2005 to 2100, i.e., a reduction from 4.03/3.71 to 3.54/3.56 Tg N yr-1 depending on the parameterization. The emissions decrease strongly in the western basins of the Pacific and Atlantic oceans, while they tend to increase above the Oxygen Minimum Zones (OMZs), i.e., in the Eastern Tropical Pacific and in the northern Indian Ocean. The reduction in N2O emissions is caused on the one hand by weakened nitrification as a consequence of reduced primary and export production, and on the other hand by stronger vertical stratification, which reduces the transport of N2O from the ocean interior to the ocean surface. The higher emissions over the OMZ are linked to an expansion of these zones under global warming, which leads to increased N2O production associated primarily with denitrification. From the perspective of a global climate system, the averaged feedback strength associated with the projected decrease in oceanic N2O emissions amounts to around -0.009 W m-2 K-1, which is comparable to the potential increase from terrestrial N2O sources. However, the assesment for a compensation between the terrestrial and marine feedbacks calls for an improved representation of N2O production terms in fully coupled next generation of Earth System Models.

  4. Global peat erosion risk assessment for the 21st Century

    Many peatlands across the world are suffering from degradation and erosion exacerbated by human influences. Blanket peat erosion has adverse impacts on terrestrial and aquatic habitats, reservoir capacity and water quality, and also leads to accelerated carbon release. Bioclimatic modelling suggests that some areas, which are currently suitable for active peat growth, may be no longer under a climate supporting the accumulation of peat by the end of the century. Peat erosion in these marginal regions is thus more likely. A recently developed blanket peat erosion model, PESERA-PEAT, was established through significantly modifying the grid version of the Pan-European Soil Erosion Assessment model (PESERA-GRID) to explicitly include the freeze-thaw and desiccation processes, which appear to be the crucial drivers of peat erosion, and typical land management practices in blanket peatlands such as artificial drainage, grazing and managed burning. Freeze-thaw and desiccation are estimated based on climate (i.e. temperature) and soil moisture conditions. Land management practices interact with hydrology, erosion and vegetation growth via their influence on vegetation cover, biomass and soil moisture condition. The model has been demonstrated to be robust for blanket peat erosion modelling with riverine sediment flux data in the UK. In this paper, the PESERA-PEAT model is applied to investigate the impact of environmental change on the blanket peat erosion at a global scale. Climatic scenarios to the end of 21st Century were derived, as part of the QUEST-GSI initiative, from the outputs of seven global climate models: CGCM3 and CCCMA (Canada); CSIRO Mark III (Australia); IPSL (France); ECHAM5 (Germany); CCSM (US National Centre for Atmospheric Research (NCAR)); HadCM3 and HadGEM1 (UK). Land management practice such as artificial drainage is considered to examine if it is possible to buffer the impact of climate change on erosion through managing blanket peatlands in

    1999-12-01

    The new energy strategy developed by Russian scientists and specialists working in the International Fuel and Energy Association is a doctrine for the further liberalization of the energy sector; pooling of new know-how and efforts of the world community for economic progress; rejecting established stereotypes of lifestyles based on inefficient energy use thereby improving the quality of life; increasing the role and responsibilities of the individual in the process of arresting environment degradation; ensuring gradual decreases in energy consumption at existing costs; and reducing social divides. The article outlines the two stages of the strategy for the development of the energy sector, the first until the year 2030, the second extending to the middle of the 21st century. The first stage will give priority to natural gas usage and intensification of energy conservation measures, the second will tackle the problems of balancing the shares of petroleum, coal and natural gas, develop new and renewable energy and strengthen the resource-technological base of the coal industry and of nuclear energy. The importance of interaction with the government, the international community, social organisations and with the energy sector companies and commercial banks is discussed. 1 ref.

    The end of the Cold War brought with it many protracted internal conflicts and wars that have lasted for decades and whose persistent instability lies at the heart of both chronic nation-state and regional instability. Responsibility for these chronically failed states has been attributed to multiple unresolved root causes. With previous governance and parties to power no longer trusted or acceptable, the vacuum of leadership in many cases has been filled with "bad leadership." This Concept piece argues that in a number of cases opportunistic leaders, suffering from severe antisocial character disorders, have emerged first as saviors and then as despots, or as common criminals claiming to be patriots, sharing a psychological framework that differs little from those responsible for World War II and the Cold War that followed. I describe the identifying characteristics of this unique and poorly understood subset of the population who are driven to seek the ultimate opportunity to control, dictate, and live out their fantasies of power on the world scene and discuss why their destructive actions remain unabated in the 21st century. Their continued antisocial presence, influence, and levels of violence must be seen as a global security and strategic issue that is not amenable to conventional diplomatic interventions, negotiations, mediations, or international sanctions.

  12. Afghanistan’s significance for Russia in the 21st Century: Interests, Perceptions and Perspectives

    2016-04-01

    Full Text Available Since President Barack Obama set the end of 2014 as the deadline to complete the planned troop withdrawal from Afghanistan, numerous commentators have sought to assess Russia’s Afghan policy since September 11, 2001 and anticipate Moscow’s strategy in ‘post-2014’ Afghanistan. This paper maintains that an assessment/evaluation of Afghanistan’s significance for Russia in the current system of international relations is needed to understand Moscow’s current and future Afghan strategy. Hence, the aim of this study is to identify and analyse the major factors, which lead to a conceptualization of Russia’s interests in Afghanistan. When assessing Russia’s interests in Afghanistan, one must take into account a plethora of significant issues, including Putin’s ‘great-power’ rhetoric; geopolitical, geostrategic, and geo-economic rivalries in the wider region; security threats such as the illegal narcotics emanating from Afghanistan and global terrorism and Islamic fundamentalism; the rivalry and competition for energy resources; and control over pipeline routes and energy corridors. The analysis of these substantiating factors demonstrate why in the 21st century the Afghan problem remains a significant challenge to Russia’s ‘great power’ identity, to its international strategy abroad, to its strategically important ‘near abroad,’ and to the country’s domestic socio-economic policy

  13. Emerging technologies for the detection of rabies virus: challenges and hopes in the 21st century.

    Directory of Open Access Journals (Sweden)

    Anthony R Fooks

    Full Text Available The diagnosis of rabies is routinely based on clinical and epidemiological information, especially when exposures are reported in rabies-endemic countries. Diagnostic tests using conventional assays that appear to be negative, even when undertaken late in the disease and despite the clinical diagnosis, have a tendency, at times, to be unreliable. These tests are rarely optimal and entirely dependent on the nature and quality of the sample supplied. In the course of the past three decades, the application of molecular biology has aided in the development of tests that result in a more rapid detection of rabies virus. These tests enable viral strain identification from clinical specimens. Currently, there are a number of molecular tests that can be used to complement conventional tests in rabies diagnosis. Indeed the challenges in the 21st century for the development of rabies diagnostics are not of a technical nature; these tests are available now. The challenges in the 21st century for diagnostic test developers are two-fold: firstly, to achieve internationally accepted validation of a test that will then lead to its acceptance by organisations globally. Secondly, the areas of the world where such tests are needed are mainly in developing regions where financial and logistical barriers prevent their implementation. Although developing countries with a poor healthcare infrastructure recognise that molecular-based diagnostic assays will be unaffordable for routine use, the cost/benefit ratio should still be measured. Adoption of rapid and affordable rabies diagnostic tests for use in developing countries highlights the importance of sharing and transferring technology through laboratory twinning between the developed and the developing countries. Importantly for developing countries, the benefit of molecular methods as tools is the capability for a differential diagnosis of human diseases that present with similar clinical symptoms.

  15. The role of HFCs in mitigating 21st century climate change

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available There is growing international interest in mitigating climate change during the early part of this century by reducing emissions of short-lived climate pollutants (SLCPs, in addition to reducing emissions of CO2. The SLCPs include methane (CH4, black carbon aerosols (BC, tropospheric ozone (O3 and hydrofluorocarbons (HFCs. Recent studies have estimated that by mitigating emissions of CH4, BC, and O3 using available technologies, about 0.5 to 0.6 °C warming can be avoided by mid-21st century. Here we show that avoiding production and use of high-GWP (global warming potential HFCs by using technologically feasible low-GWP substitutes to meet the increasing global demand can avoid as much as another 0.5 °C warming by the end of the century. This combined mitigation of SLCPs would cut the cumulative warming since 2005 by 50% at 2050 and by 60% at 2100 from the CO2-only mitigation scenarios, significantly reducing the rate of warming and lowering the probability of exceeding the 2 °C warming threshold during this century.

    2012-01-01

    Future changes in the climate regimes over China as measured by the Kppen climate classification are reported in this paper. The analysis is based on a high-resolution climate change simulation conducted by a regional climate model (the Abdus Salam International Center for Theoretical Physics (ICTP) RegCM3) driven by the global model of Center for Climate System Research (CCSR)/National Institute for Environment Studies (NIES)/Frontier Research Center for Global Change (FRCGC) MIROC3.2_hires (the Model for Interdisciplinary Research on Climate) under the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES) A1B scenario. Validation of the model performances is presented first. The results show that RegCM3 reproduces the present-day distribution of the Kppen climate types well. Significant changes of the types are found in the future over China, following the simulated warming and precipitation changes. In southern China, the change is characterized by the replacement of subtropical humid (Cr) by subtropical winter-dry (Cw). A pronounced decrease of the cold climate types is found over China, e.g., tundra (Ft) over the Tibetan Plateau and sub-arctic continental (Ec) over northeast China. The changes are usually greater in the end compared with the middle of the 21st century.

    Inflammatory bowel disease (IBD) has been an international hot spot for research for a long period of time. In China, the prevalence of IBD is rapidly increasing in recent years, mimicking the same fast growing footsteps of the developed world. Chinese literature of the 20(th) century shows that the total number of IBD cases increased by approximately 2.5-fold over the previous decade, in particular a 15.7-fold in patients with Crohn's disease (CD). Articles on basic research have increased 4.3-fold, with a particular 9.9-fold increase on immunological mechanisms. The predominantly Traditional Chinese Medicine (TCM) related clinical trials implied tendency to use a combination of Western Medicine and TCM in the management of Chinese IBD patients. IBD research and collaborations overseas have been markedly promoted since the Chinese Organization for the Study of Inflammatory Bowel Disease (COIBD) was founded at the beginning of the 21(st) century. From the second decade of the century onwards, we need to focus on the research hot spots to catch up with the rapid advances worldwide. Big challenges and present achievements provide us with great opportunities for further developments of the study on IBD. The development of some novel target pathogenic factors of the disease will provide us with more effective roll for modern management and optimistic treatment of IBD during this century.

    We investigate the effects of a recently proposed 21st century Dalton minimum like decline of solar activity on the evolution of Earth's climate and ozone layer. Three sets of two member ensemble simulations, radiatively forced by a midlevel emission scenario (Intergovernmental Panel on Climate Change RCP4.5), are performed with the atmosphere-ocean chemistry-climate model AOCCM SOCOL3-MPIOM, one with constant solar activity, the other two with reduced solar activity and different strength of the solar irradiance forcing. A future grand solar minimum will reduce the global mean surface warming of 2 K between 1986-2005 and 2081-2100 by 0.2 to 0.3 K. Furthermore, the decrease in solar UV radiation leads to a significant delay of stratospheric ozone recovery by 10 years and longer. Therefore, the effects of a solar activity minimum, should it occur, may interfere with international efforts for the protection of global climate and the ozone layer.

  19. The Thrill of Discovery: Nuclear Physics Research in the 21st Century

    International Nuclear Information System (INIS)

    To many people outside our field, both scientists and the general public, nuclear physics is no longer regarded as being at the forefront of scientific endeavour. Indeed it is often met with outright hostility. Other physicists will point out that the last time a Nobel Prize was awarded in the field was in 1975. This paper, based on a lecture delivered during an Open Plenary Session of the recent International Nuclear Physics Conference INPC2004, which was aimed at a non-specialist audience, will seek to dispel this myth. Nuclear physics is currently enjoying a period of rapid advances. Many new discoveries have been made in the past few years, from neutron halos and nuclear molecules to a new form of radioactive decay via two protons; from hints of a new particle consisting of five quarks to new 'superheavy' elements. This talk will give a personal perspective on why, far from looking with envy at our neighbours in areas of physics that currently enjoy a higher media profile, we have more than enough to keep us busy and excited in the 21st century

    Full Text Available Significant changes have taken place in the demographics of Turkey in the remaining timeframe of the 21st century in addition to the changes incurring in other areas. The aim of this study was to analyze the statistical and spatial distribution of migrations inter provincial in Turkey between the years 2007-2012. The results of the analyses were compared with the results for previous periods and the similarities and differences in terms of interprovincial migrations were determined. During the last five years of the 21st century 2.3 million people have migrated from one province to another per year to total over 11.6 million people (15,3% of the total population. These figures show that more than twice the number of people compared to previous years migrated to another province. Although the percentage of the migrating population has increased, only 1/3 of the provinces in Turkey have been at the receiving end of this migration. The spatial analyses have determined that the difference between the eastern and western parts of Turkey in terms of internal migration continues. In other words, it has been determined that no significant changes in the net migration map of Turkey have incurred.

    Neisseria gonorrhoeae is a strictly human pathogen that is typically transmitted by sexual contact. The associated disease gonorrhea has plagued humankind for thousands of years, with a current estimated incidence of 78 million cases per year. Advances in antimicrobial discovery in the 1920s and 1930s leading to the discovery of sulfonamides and penicillin begun the era of effective antimicrobial treatment of gonorrhea. Unfortunately, the gonococcus developed decreased susceptibility or even resistance to these initially employed antibiotics, a trend that continued over subsequent decades with each new antibiotic that was brought into clinical practice. As this pattern of resistance has continued into the 21st century, there is now reason for great concern, especially in an era when few new antibiotics have prospects for use as treatment of gonorrhea. Here, we review the history of gonorrhea treatment regimens and gonococcal resistance to antibiotics, the mechanisms of resistance, resistance monitoring schemes that exist in different international settings, global responses to the challenge of resistance, and prospects for future treatment regimens in the 21st century.

    The evolution of stratospheric ozone from 1960 to 2100 is examined in simulations from 14 chemistry-climate models, driven by prescribed levels of halogens and greenhouse gases. There is general agreement among the models that total column ozone reached a minimum around year 2000 at all latitudes, projected to be followed by an increase over the first half of the 21st century. In the second half of the 21st century, ozone is projected to continue increasing, level off, or even decrease depending on the latitude. Separation into partial columns above and below 20 hPa reveals that these latitudinal differences are almost completely caused by differences in the model projections of ozone in the lower stratosphere. At all latitudes, upper stratospheric ozone increases throughout the 21st century and is projected to return to 1960 levels well before the end of the century, although there is a spread among models in the dates that ozone returns to specific historical values. We find decreasing halogens and declining upper atmospheric temperatures, driven by increasing greenhouse gases, contribute almost equally to increases in upper stratospheric ozone. In the tropical lower stratosphere, an increase in upwelling causes a steady decrease in ozone through the 21st century, and total column ozone does not return to 1960 levels in most of the models. In contrast, lower stratospheric and total column ozone in middle and high latitudes increases during the 21st century, returning to 1960 levels well before the end of the century in most models.

    The evolution of damage to building materials has been estimated for the 21st century, with a particular focus on aluminum, zinc, copper, plastic, paint, and rubber in urban areas. We set idealized air pollution and climates to represent London and Prague across the period 1950-2100. Environmental parameters were used to estimate future recession, corrosion, and loss of properties through published damage or dose-response functions. The 21st century seems to provide a less aggressive environment for stone and metals than recent times. Improvements in air quality are the most relevant drivers for this amelioration. Changes in climate predicted for the 21st century do not alter this picture. On the other hand, polymeric materials, plastic, paint, and rubber might show slightly increased rates of degradation, to some extent the result of enhanced oxidant concentrations, but also the possibility of contributions from more solar radiation.

In the 21st century, the compelling technology will be that of the micro-world, enabling the fabrication of structures with features smaller than the wavelengths of light. Such structures will allow use to monitor and control electrical, chemical, and optical phenomena in ways never before imagined. As in the past we will continue to create monuments, but the technological monuments of the 21st century will likely be viewed through a microscope. This report provides a discussion of microtechnology in the 21st century.

  8. Potential Damage to Modern Building Materials from 21st Century Air Pollution

    Directory of Open Access Journals (Sweden)

    Peter Brimblecombe

    2010-01-01

    Full Text Available The evolution of damage to building materials has been estimated for the 21st century, with a particular focus on aluminum, zinc, copper, plastic, paint, and rubber in urban areas. We set idealized air pollution and climates to represent London and Prague across the period 1950–2100. Environmental parameters were used to estimate future recession, corrosion, and loss of properties through published damage or dose-response functions. The 21st century seems to provide a less aggressive environment for stone and metals than recent times. Improvements in air quality are the most relevant drivers for this amelioration. Changes in climate predicted for the 21st century do not alter this picture. On the other hand, polymeric materials, plastic, paint, and rubber might show slightly increased rates of degradation, to some extent the result of enhanced oxidant concentrations, but also the possibility of contributions from more solar radiation.

  9. Ares V: A National Launch Asset for the 21st Century

    2009-01-01

    NASA is designing the Ares V as the cargo launch vehicle to carry NASA's exploration plans into the 21st century. The Ares V is the heavy-lift component of NASA's dual-launch architecture that will replace the current space shuttle fleet, complete the International Space Station, and establish a permanent human presence on the Moon as a stepping stone to destinations beyond. During extensive independent and internal architecture and vehicle trade studies as part of the Exploration Systems Architecture Study, NASA selected the Ares I crew launch vehicle and the Ares V to support future exploration. The smaller Ares I will launch the Orion crew exploration vehicle with four to six astronauts into orbit. The Ares V is designed to carry the Altair lunar lander into orbit, rendezvous with Orion, and send the mated spacecraft toward lunar orbit. The Ares V will be the largest and most powerful launch vehicle in history, providing unprecedented payload mass and volume to establish a permanent lunar outpost and explore significantly more of the lunar surface than was done during the Apollo missions. The Ares V also represents a national asset offering opportunities for new science, national security, and commercial missions of unmatched size and scope. Using the dual-launch Earth Orbit Rendezvous approach, the Ares I and Ares V together will be able to inject roughly 57percent more mass to the Moon than the Apollo-era Saturn V. Ares V alone will be able to send nearly 414,000 pounds into low Earth orbit (LEO) or more than 138,000 pounds directly to the Moon, compared with 262,000 pounds and 99,000 pounds, respectively for the Saturn V. Significant progress has been made on the Ares V to support a planned fiscal 2011 authority-to-proceed (ATP) milestone. This paper discusses recent progress on the Ares V and planned future activities.

    2012-12-01

    Full Text Available There is growing international interest in mitigating climate change during the early part of this century by reducing emissions of short-lived climate pollutants (SLCPs, in addition to reducing emissions of CO2. The SLCPs include methane (CH4, black carbon aerosols (BC, tropospheric ozone (O3 and hydrofluorocarbons (HFCs. Recent studies have estimated that by mitigating emissions of CH4, BC, and O3 using available technologies, about 0.5 to 0.6 °C warming can be avoided by mid-21st century. Here we show that avoiding production and use of high-GWP (global warming potential HFCs by using technologically feasible low-GWP substitutes to meet the increasing global demand can avoid as much as another 0.5 °C warming by end of the century, therefore significantly reducing the rate of warming and lowering the probability of exceeding the 2 °C warming threshold during this century.

  13. Leo Szilard Lectureship Award: The Public Obligation of Scientists in the 21st Century

    Science.gov (United States)

    Kelly, Henry

    2002-04-01

    As many as ten billion people may be alive at the end of the 21st century. Without order-of-magnitude changes in the productivity of systems for satisfying this population’s needs and whimsies, we face starkly growing worldwide inequality, unsustainable plundering of shrinking supplies of natural resources, or both. Can we invent energy sources that are sustainable, affordable, and consistent with security? Can we mimic the ability of biological systems and build small, inexpensive machines that can fabricate tens of thousands of products on demand from simple raw materials? Can we use information and communication systems to optimize design and performance (the human brain uses half the energy of modern Pentium chips but most people seem much more clever.) Can we cut the resources needed to move people and things from point to point or to maintain homes and office spaces with comfortable light by an order of magnitude? As an APS summer study proved nearly three decades ago, there is much room for optimism about what we can do to address these problems and much has been learned since this initial foray. But there is there less room to be optimistic about changing incentive systems to reflect what we collectively want to do. Scientists who recognize what is possible can not in conscience ignore the complex, frustrating, and morally perilous world of domestic and international politics. Learning to be effective is not easy. Understanding political systems is not easy and being effective means engaging in the agonizing business of sorting through third or fourth-best solutions that are vastly better than no solution at all. The century can not end well without an effective partnership between science and politics.

    Bazell, Carol; Davis, Howard; Glass, Jerilyn; Rodak, John; Bastacky, Stanford M

    2004-01-01

    The Undergraduate Medical Education for the 21st Century (UME-21) project was implemented by the Division of Medicine, Bureau of Health Professions, Health Resources and Services Administration (HRSA) to encourage medical schools to collaborate with managed care organizations and others. The purpose of the collaboration was to ensure that medical students are prepared to provide quality patient care and manage that care in an integrated health care system in which the cost of care and use of empirically justified care are important elements. The UME-21 project represents a continuation of HRSA's interest in the managed care arena. The UME-21 project involved the collaboration of eight partner schools and 10 associate partner schools, together with 50 external partners, to develop innovative curricula that integrated UME-21 content from nine special areas as learning objectives. This project demonstrated that concerted efforts by the leadership in medical education can bring about innovative change in medical school curricula. It ís also demonstrated that faculty of the three primary care disciplines of family medicine, general internal medicine, and general pediatrics were able to cooperate to accomplish such change by working together to allocate clerkship time and content. An important lesson learned in this project was that significant innovations in medical school curricula could be accomplished with a broadbased commitment and involvement of both faculties across the three primary care disciplines and top administrative officials of the medical school. It is uncertain, however, if the innovations achieved will produce further changes or if those changes achieved can be sustained without continued funding.

  15. Projections of Wind Changes for 21st Century in China by Three Regional Climate Models

    Institute of Scientific and Technical Information of China (English)

    JIANG Ying; LUO Yong; ZHAO Zongci; SHI Ying; XU Yinlong; ZHU Jinhong

    2010-01-01

    This paper examines the capability of three regional climate models(RCMs),i.e.,RegCM3(the International Centre for Theoretical Physics Regional Climate Model),PRECIS(Providing Regional Climates for Impacts Studies)and CMM5(the fifth-generation Pennsylvania State University-the National Center for Atmospheric Research of USA,NCAR Mesoscale Model)to simulate the near-surface-layer winds(10 m above surface)all over China in the late 20th century.Results suggest that like global climate models(GCMs),these RCMs have the certain capability of imitating the distribution of mean wind speed and fail to simulate the greatly weakening wind trends for the past 50 years in the country.However,RCMs especially RegCM3 have the better capability than that of GCMs to simulate the distribution and change feature of mean wind speed.In view of their merits,these RCMs were used to project the variability of near-surface-layer winds over China for the 21st century.The results show that 1)summer mean wind speed for 2020-2029 will be lower compared to those in 1990-1999 in most area of China; 2)annual and winter mean wind speed for 2081-2100 will be lower than those of 1971-1990 in the whole China; and 3)the changes of summer mean wind speed for 2081-2100 are uncertain.As a result,although climate models are absolutely necessary for projecting climate change to come,there are great uncertainties in projections,especially for wind speed,and these issues need to be further explored.

  16. Cold-fusion as safe and hazardless energy-source of the 21st century

    International Nuclear Information System (INIS)

    Out of the two processes for nuclear-energy; nuclear-fission is plagued with problem of nuclear-radiation hazard, whereas though nuclear-fusion is safe but almost impossible to be done on earth specially at room- temperature. In 1989, two scientists Fleischmann and Pons in USA proposed a table-top, room temperature electrolysis-experiment of heavy-water with palladium-electrode; this is commonly called cold-fusion wherein nuclear-fusion is said to be taking place. This created a big storm and controversy in the scientific community. Initially the cold-fusion was heavily criticized and several objections (such as: non-reproducibility, non-observation of telltale signature of nuclear-reaction) were raised. The research-work of McKubre and others have clarified the objections and have established that for cold-fusion to take place certain threshold conditions (such as purity of electrode, current-density, deuterium to palladium loading ratio) needs to be satisfied. In due course of time, the Truth prevailed and the cold-fusion got more and more support by many scientists in several countries including India (BARC historic role has been appreciated worldwide). Biggest objection, however, was lack of a proper theory for how Coulomb-repulsion is overcome in cold-fusion. A possible explanation for how the Coulomb-repulsion is overcome, is given in this paper; which is based on a new-found Gupta-Dinu effect, which is a natural outcome of special-relativity via modification in Lorentz force formula. The recent nuclear-accidents have raised international-opinion against nuclear-fission, whereas sin-like hot-fusion on earth is not possible. Now it seems that ultimately it is the cold-fusion which will provide hazardless neat and cheap energy for the 21st century and India could play a leading role in this direction. (author)

    2005-01-01

    Full Text Available Nowadays, an unrealistic common sense on the understanding of the phenomenon of the war prevails in the Occident. That may be explained by the transformation of the analytical perspective of the State into one of the civil society, as well as of the historical loss of the meaning of human action. The text argues that the criticism to the unilateralism of the USA hides serious problems of reality perception that hinders the development of the debate in the area of the international relations. The conclusion is that the current international order is in transition, having been brokered by the emergency of the global terrorism, that ended up leading the USA to take over a strong warlike decisionism against any kind of threat to the global safety.

  18. Radiological protection philosophy for the 21st century

    International Nuclear Information System (INIS)

    The International Commission on Radiological Protection (ICRP) has stated that its recommendations will be reviewed at least every 10-15 years. It is now some 13 years since the main commission released, for comment, a draft of what was to become the 1990 Recommendations of the ICRP. These have become the basis for international basic safety standards and have been adopted in almost all countries that have radiological protection legislation. Therefore, the ICRP has been stimulating discussion, during the last three years, on the best was of expressing protection philosophy for the next publication of its recommendations, which it hopes will be by 2005. It is now beginning to prepare a draft of these recommendations, with a view to distributing an early version for comment, even though the background work is incomplete. (author)

    2008-01-01

    The projected changes in carbon exchange between China terrestrial ecosystem and the atmosphere and vegetation and soil carbon storage during the 21st century were investigated using an atmos-phere-vegetation interaction model (AVIM2). The results show that in the coming 100 a, for SRES B2 scenario and constant atmospheric CO2 concentration, the net primary productivity (NPP) of terrestrial ecosystem in China will be decreased slowly, and vegetation and soil carbon storage as well as net ecosystem productivity (NEP) will also be decreased. The carbon sink for China terrestrial ecosystem in the beginning of the 20th century will become totally a carbon source by the year of 2020, while for B2 scenario and changing atmospheric CO2 concentration, NPP for China will increase continuously from 2.94 GtC.a-1 by the end of the 20th century to 3.99 GtC.a-1 by the end of the 21st century, and vegetation and soil carbon storage will increase to 110.3 GtC. NEP in China will keep rising during the first and middle periods of the 21st century, and reach the peak around 2050s, then will decrease gradually and approach to zero by the end of the 21st century.

D.; Rinaldi, M.; Facchini, M. C.; Flechard, C. R.; Nemitz, E.; Twigg, M.; Erisman, J. W.; Butterbach-Bahl, K.; Galloway, J. N.

    2015-12-01

    The global nitrogen (N) cycle at the beginning of the 21st century has been shown to be strongly influenced by the inputs of reactive nitrogen (Nr) from human activities, including combustion-related NOx, industrial and agricultural N fixation, estimated to be 220 Tg N yr-1 in 2010, which is approximately equal to the sum of biological N fixation in unmanaged terrestrial and marine ecosystems. According to current projections, changes in climate and land use during the 21st century will increase both biological and anthropogenic fixation, bringing the total to approximately 600 Tg N yr-1 by around 2100. The fraction contributed directly by human activities is unlikely to increase substantially if increases in nitrogen use efficiency in agriculture are achieved and control measures on combustion-related emissions implemented. Some N-cycling processes emerge as particularly sensitive to climate change. One of the largest responses to climate in the processing of Nr is the emission to the atmosphere of NH3, which is estimated to increase from 65 Tg N yr-1 in 2008 to 93 Tg N yr-1 in 2100 assuming a change in global surface temperature of 5 °C in the absence of increased anthropogenic activity. With changes in emissions in response to increased demand for animal products the combined effect would be to increase NH3 emissions to 135 Tg N yr-1. Another major change is the effect of climate changes on aerosol composition and specifically the increased sublimation of NH4NO3 close to the ground to form HNO3 and NH3 in a warmer climate, which deposit more rapidly to terrestrial surfaces than aerosols. Inorganic aerosols over the polluted regions especially in Europe and North America were dominated by (NH4)2SO4 in the 1970s to 1980s, and large reductions in emissions of SO2 have removed most of the SO42- from the atmosphere in these regions. Inorganic aerosols from anthropogenic emissions are now dominated by NH4NO3, a volatile aerosol which contributes substantially to PM10

  7. Nuclear energy and materials in the 21st century

    International Nuclear Information System (INIS)

    The Global Nuclear Vision Project at the Los Alamos National Laboratory is examining a range of long-term nuclear energy futures as well as exploring and assessing optimal nuclear fuel-cycle and material strategies. An established global energy, economics, environmental (E3) model has been adopted and modified with a simplified, but comprehensive and multi-regional, nuclear energy module. Consistent nuclear energy scenarios are constructed, where future demands for nuclear power are projected in price competition with other energy sources under a wide range of long-term (∼2100) demographic, economic, policy, and technological drivers. A spectrum of futures is examined at two levels in a hierarchy of scenario attributes in which drivers are either external or internal to nuclear energy. The result reported examine departures from a basis scenario and are presented in the following order of increasing specificity: (a) definition and parametric variations of the basis scenario; (b) comparison of the basis scenario with other recent studies; (c) parametric studies that vary upper-level hierarchical scenario attributes (external drivers); and (d) variations of the lower-level scenario attributes (internal drivers). Impacts of a range of nuclear fuel-cycle scenarios are reflected back to the higher-level scenario attributes that characterize particular nuclear energy scenarios. Special attention is given to the role of nuclear materials inventories (in magnitude, location, and form) and their contribution to the long-term sustainability of nuclear energy, the future competitiveness of both conventional and advanced nuclear reactors, and proliferation risk

    The Council of Managers of National Antarctic Programs' (COMNAP) Antarctic Roadmap Challenges(ARC) project translated the 80 highest priority Antarctic and Southern Ocean scientific questionsidentified by the community via the SCAR Antarctic Science Horizon Scan into the highest prioritytechnological, access, infrastructure and logistics needs to enable the necessary research to answer thequestions. A workshop assembled expert and experienced Antarctic scientists and National AntarcticProgram operators from around the globe to discern the highest priority technological needs includingthe current status of development and availability, where the technologies will be utilized in the Antarctic area, at what temporal scales and frequencies the technologies will be employed,and how broadly applicable the technologies are for answering the highest priority scientific questions.Secondly the logistics, access, and infrastructure requirements were defined that are necessary todeliver the science in terms of feasibility including cost and benefit as determined by expected scientific return on investment. Finally, based on consideration of the science objectives and the mix oftechnologies implications for configuring National Antarctic Program logistics capabilities andinfrastructure architecture over the next 20 years were determined. In particular those elements thatwere either of a complexity, requiring long term investments to achieve and/or having an associated cost that realistically can only (or best) be achieved by international coordination, planning and partnerships were identified. Major trends (changes) in logistics, access, and infrastructure requirements were identified that allow for long-term strategic alignment of international capabilities, resources and capacity. The outcomes of this project will be reported.

    Full Text Available Over the past decade there has been a growing recognition of the involvement of the home in several public health and hygiene issues. Perhaps the best understood of these issues is the role of the home in the transmission and acquisition of foodborne disease. The incidence of foodborne disease is increasing globally. Although foodborne disease data collection systems often miss the mass of home-based outbreaks of sporadic infection, it is now accepted that many cases of foodborne illness occur as a result of improper food handling and preparation by consumers in their own kitchens. Some of the most compelling evidence has come from the international data on Salmonella species and Campylobacter species infections.

    It is my pleasure to talk to you today about "global water security" at the Erice International Seminars 46th Session focused on "The Role of Science in the Third Millennium." The growing importance of water security can be framed in two ways. First, water resources should be protected so that, on a reliable basis, there is sufficient, safe water to sustain the health and livelihoods of populations, while also increasing their resilience to water-related hazards such as floods and droughts. Second, the geopolitical dimensions of water security should be addressed by considering how water shortages, poor water quality, or floods might impact the stability or failure of states, increase regional tensions, and pose a risk to global public health and food markets, thus hobbling economic growth.

    Full Text Available During the present time, the debate regarding European minorities is a problem of high interest. Even if it is a discussion of Basques and Catalans, Turks and Greeks in Cyprus, Catholics and Protestants in Northern Ireland, Hungarians in Romania or genocide in the former Yugoslavia, the matter is high on the agenda. After centuries of confrontations in Europe, the European Union tries to legitimate the issue of national minorities, willing to eliminate any kind of discrimination and to preserve cultural identity. Recommendation 1201/1993 of the Council of Europe intended to draw up an additional protocol on the rights of minorities to the European Convention of Human Rights in order to provide the Council with a suitable mediation instrument.Considering the diversity of peoples and cultures living for centuries within the European space and their important contribution to the cultural development of the European states and civilization, the Recommendation seeks to recognize the rights of persons belonging to a national minority within a state and the international protection of those rights as an aspect of international co-operation, able to end the ethnic, linguistic and religious confrontations, and to guarantee justice, democracy and peace [1]. Nevertheless, at the beginning of the third millennium, the topic of minorities is still an actual one.Antony Alcock’s [2] book, A History of the Protection of Regional Cultural Minorities in Europe (From the Edict of Nantes to the Present Days, is an important study of the main historical events that changed the European approach of the issue of national minorities, providing an original account of the historical foundations of this direction of research. The book is divided in five parts, with seven chapters in total, accompanied by an introductory study, a comprehensive conclusion, two appendixes (one showing the main minorities and the percentage from the total population in 37 European states

    A major part of technological advancement has involved the development of complex infrastructure systems, including electric power generation, transmission, and distribution networks; oil and gas pipeline systems; highway and rail networks; and telecommunication networks. Dependence on these infrastructure systems renders them attractive targets for conflict in the twenty-first century. Hostile governments, domestic and international terrorists, criminals, and mentally distressed individuals will inevitably find some part of the infrastructure an easy target for theft, for making political statements, for disruption of strategic activities, or for making a nuisance. The current situation regarding the vulnerability of the infrastructure can be summarized in three major points: (1) our dependence on technology has made our infrastructure more important and vital to our everyday lives, this in turn, makes us much more vulnerable to disruption in any infrastructure system; (2) technologies available for attacking infrastructure systems have changed substantially and have become much easier to obtain and use, easy accessibility to information on how to disrupt or destroy various infrastructure components means that almost anyone can be involved in this destructive process; (3) technologies for defending infrastructure systems and preventing damage have not kept pace with the capability for destroying such systems. A brief review of these points will illustrate the significance of infrastructure and the growing dangers to its various elements.

    Curated databases are an integral part of the tool set that researchers use on a daily basis for their work. For most users, however, how databases are maintained, and by whom, is rather obscure. The International Society for Biocuration (ISB) represents biocurators, software engineers, developers and researchers with an interest in biocuration. Its goals include fostering communication between biocurators, promoting and describing their work, and highlighting the added value of biocuration to the world. The ISB recently conducted a survey of biocurators to better understand their educational and scientific backgrounds, their motivations for choosing a curatorial job and their career goals. The results are reported here. From the responses received, it is evident that biocuration is performed by highly trained scientists and perceived to be a stimulating career, offering both intellectual challenges and the satisfaction of performing work essential to the modern scientific community. It is also apparent that the ISB has at least a dual role to play to facilitate biocurators' work: (i) to promote biocuration as a career within the greater scientific community; (ii) to aid the development of resources for biomedical research through promotion of nomenclature and data-sharing standards that will allow interconnection of biological databases and better exploit the pivotal contributions that biocurators are making.

    The current situation and possible future developments for nuclear power--including fission and fusion processes--is presented. The fission nuclear power continues to be an essential part of the low-carbon electricity generation in the world for decades to come. There are breakthrough possibilities in the development of new generation nuclear reactors where the life-time of the nuclear waste can be reduced to some hundreds of years instead of the present time-scales of hundred thousand of years. Research on the fourth generation reactors is needed for the realisation of this development. For the fast nuclear reactors, a substantial research and development effort is required in many fields--from material sciences to safety demonstration--to attain the envisaged goals. Fusion provides a long-term vision for an efficient energy production. The fusion option for a nuclear reactor for efficient production of electricity has been set out in a focussed European programme including the international project of ITER after which a fusion electricity DEMO reactor is envisaged.

    Abstract: The Internet was designed in 1973, began operation in 1983, became widely known to the general public in 1993 and now has become a global infrastructure for all forms of communication. The network is relatively unaware of the applications that use it and also relatively insensitive to the technologies that transport its Internet "packets" around the world. Where did the Internet come from? What is its condition today? How will it be used tomorrow? What might we expect it to look like in the next decade? What technical and international policy challenges does the Internet pose? Could it be made to operate across our solar system to support manned and robotic exploration? Answers to these questions and more will be provided in this presentation. Short Biography: Vinton G. Cerf is vice president and chief Internet evangelist for Google.

    The development of superconducting materials and the development of helium temperature refrigeration technology have both been propelled by their wide application in large-scale scientific research. The development of materials and technology for the Tevatron proton storage ring at Fermi National Accelerator Laboratory, Batavia, IL USA, in the decade of the seventies provided the basis in the decade of the eighties, for example, for the use of superconducting helium-cooled whole-body magnets for magnetic resonance imaging in medical diagnosis. In the decade of the nineties a number of particle accelerators for high energy physics will be constructed in national and international laboratories around the world. These devices will employ superconductivity on an ambitious scale, and their operation will require more than double the amount of helium refrigeration capacity now installed worldwide. This large increase in the use of helium refrigeration will have a significant effect on the technology and on the industry that produces it. The largest of these accelerator projects is the Superconducting Super Collider (SSC) now under construction at a new laboratory near Dallas, TX USA. This report discusses the development of this cryogenic system for the SSC magnets.

    Full Text Available The usual procedures for ecological risk assessment (ERA have been based for decades on simplified approaches in order to provide basic information on the huge amount of chemicals introduced into the environment. These approaches allowed the development of international regulatory tools capable of substantially reducing the adverse effects on ecosystems in developed countries. Nevertheless, these approaches suffer from a lack of ecological realism and are poorly suitable for understanding the actual consequences for ecosystem health. The need for more ecologically-based approaches is now recognized by the scientific community and has been highlighted by a recent document of the European Commission. In this paper, a synthesis is presented of the most important issues and the need for research to improve the ecological realism of exposure and effect assessment and the tools that should be developed to reach this objective. In particular, the major challenges are the following: the effects of variable exposure patterns; the vulnerability of ecosystems; the indirect ecological effects; the responses to multiple stress factors; the improvement of ecological modeling. The possibilities for using new scientific achievements in regulatory ERA are also discussed.

    Sustainability of development assistance programs depends greatly on the perceptions of priorities by recipient countries. A written survey was sent by the Catholic University of America's Institute for International Health and Development to 66 ministers of health in low-income and middle-income countries to assess their views of priority problems in health sector development. Response rate was 33%, coming from countries with highly diverse gross national products (GNPs), growth rates, mortality rates and life expectancies. Nevertheless, there was widespread agreement about priorities: 1) meeting costs of health care; 2) improving health care management and administration; and 3) extending communicable disease control. Communicable disease control and child health programs were more important to low-income countries than to middle-income countries. Costs, management and administration and the control of noncommunicable diseases were predicted to increase in importance. In demographics, urbanization, overall population growth and shift of workers from agriculture to industry and services were seen as the major problems of the past, and urbanization and the aging of populations accompanied by increasing life expectancies the major challenges of the future. Highest predicted training needs were for system managers and paramedical personnel. Government budgets, user fees and donor agencies were seen as the most important sources of past funding, with social security systems and fee-based payments increasing in importance in the future. The role of donor agencies would increase as would the need for more responsiveness. Future uncertainties include national economic growth, environmental problems, issues in ethics and changes in disease and technology. PMID:12342422

Different in their approach, both regard the human brain as one of the greatest challenges of 21st century science and the organ that makes us “human”. However, it is mainly the necessity of developing new therapies that affect up to a billion people worldwide, which has propelled the search for extensive expertise and investment in neuroscience research. The debate on ethical and social policy issues as well as the research and medical strategies of such gigantic efforts has involved participants as diverse as neuroscientists, philosophers, scholars in ethics and law, politicians, and the general public, rendering modern neuroscience an interdisciplinary and conflictual endeavor. In fact, the brain is described as the biological underpinning of our thoughts, emotions, perceptions, free willed actions, and memories, features unique to our humanity.

    The World Energy Council's recent study examined the potential of energy end-use technologies and of research, development, and demonstration (RD&D) into these technologies on a global scale. Surprises are likely, but nevertheless, current research and development offer a picture of what might happen in the future as new technologies face the competition of the marketplace. Given the breadth of energy end-use technologies and the differences between regions and economic conditions, the study focused on technologies that appear most important from today's vantage point. Globally, robust research and development followed by demonstrations of new end-use technologies can potentially save at least 110 EJ/year by 2020 and over 300 EJ/year by 2050. If achieved, this translates to worldwide energy savings of as much as 25% by 2020 and over 40% by 2050, over what may be required without these technologies. It is almost certain that no single technology, or even a small set of technologies, will dominate in meeting the needs of the globe in any foreseeable timeframe. Absent a significant joint government-industry effort on end-use technology RD&D, the technologies needed will not be ready for the marketplace in the timeframes required with even the most pessimistic scenarios. Based on previous detailed analyses for the United States, an international expenditure of $4 billion per year seems more than justified. The success of new energy end-use technologies depends on new RD&D investments and policy decisions made today. Governments, in close cooperation with industry, must carefully consider RD&D incentives that can help get technologies from the laboratory or test-bed to market. Any short-term impact areas are likely to benefit from focused RD&D. These include electricity transmission and distribution, distributed electricity production, transportation, the production of paper and pulp, iron and steel, aluminum, cement and chemicals, and information and

    Full Text Available The neo-populism is a socio-political phenomenon, which is characteristic of Latin America in the 21st century, but it has a clear legacy of populism found throughout the entire region in the twentieth century. Hugo Chavez was a political and military figure recognized for his social policies and practices, marked by personalism and the appeal to a direct relationship with people while planting a leftist political discourse called “Socialism of the 21st century”. This paper aims to conceptualize, from the sociological and political theories, the present situation in Latin America, with a special focus on Venezuela, and argue that Chávez must be regarded as the most outstanding figure of the neo-populism of the early twenty-first century.

    Full Text Available The article reflects on the challenges of theological education in the 21st century and in Africa. Reputation, impact, success and funding have become the driving forces of the modern university. However, we are living in the 21st century and in Africa with a subsequent frame of reference that is holistic and faith-based. The article therefore argues for a multi- and transdisciplinary approach towards the nature of a university and recognition of the unique contribution theological education can contribute. Due to the inherently cooperative nature of theological scholarship, theological education could be able to avoid the extremes of the Scylla and the Charybdis, that is, fideism and secularisation, and therefore be able to survive at an academic institution. Both sectarianism and scientism should be avoided. Theological education in Africa needed to travel the same difficult road of theological faculties in Europe in the previous century.

    In paving the way for a new electricity-based civilization in the 21st century, we hope to find the key to solving the trilemma of securing energy and resources, maintaining economic growth, and preserving the environment. In these circumstances, secondary batteries are expected to be used on a large scale in a new field—for energy purposes and to positively affect preservation of the global environment, resulting in the advent of a new battery-based society in the 21st century. It is important to develop secondary batteries not only with high specific energy for convenience, but also with large capacity, high energy efficiency and long life cycle for effective use of primary energy resources including natural energy. Lithium secondary batteries are a promising option.

    Full Text Available The 21st century shows an increase in the number of women occupying leadership positions. The challenge is: How do they lead in a context which is still male dominated? Often female leaders simply try to copy the male leadership style they are familiar with. But sometimes, in doing so, they lose their femininity and the organisation misses out on the specific opportunities of female leadership. One aim of this article is to discuss the opportunities and strengths of a female leadership style such as pro-social behaviour and a panorama view. We will also deal with the issue of how women approach power and the power bases women would typically use. One conclusion is that we need the benefits of both male and female leadership for the 21st century

    Atmospheric nitrogen deposition, nitrogen fixation, and the application of nitrogen fertilizers provide subsidies to land ecosystems that can increase nitrogen availability for vegetation production and thereby influence land carbon dynamics. In addition, enhanced decomposition of soil organic matter (SOM) from warming soils and permafrost degradation may also increase nitrogen availability in Northern Eurasia. Here, we examine how changes in nitrogen availability may influence land carbon dynamics in Northern Eurasia during the 21st century by comparing results for a "business as usual" scenario (the IPCC Representative Concentration Pathways or RCP 8.5) and a stabilization scenario (RCP 4.5) between a version of the Terrestrial Ecosystem Model that does not consider the effects of atmospheric nitrogen deposition, nitrogen fixation and soil thermal dynamics on land carbon dynamics (TEM 4.4) and a version that does consider these dynamics (TEM 6.0). In these simulations, atmospheric nitrogen deposition, nitrogen fixation, and fertilizer applications provide an additional 3.3 Pg N (RCP 4.5) to 3.9 Pg N (RCP 8.5) to Northern Eurasian ecosystems over the 21st century. Land ecosystems retain about 38% (RCP4.5) to 48% (RCP 8.5) of this nitrogen subsidy. Net nitrogen mineralization estimated by TEM 6.0 provide an additional 1.0 Pg N to vegetation than estimated by TEM 4.4 over the 21st century from enhanced decomposition of SOM including SOM formerly protected by permafrost. The enhanced nitrogen availability in TEM 6.0 allows Northern Eurasian ecosystems to sequester 1.8x (RCP 8.5) to 2.4x (RCP 4.5) more carbon over the 21st century than estimated by TEM 4.4. Our results indicate that consideration of nitrogen subsidies and soil thermal dynamics have a large influence on how simulated land carbon dynamics in Northern Eurasia will respond to future changes in climate, atmospheric chemistry, and disturbances.

    The evolution of stratospheric ozone from 1960 to 2100 is examined in simulations from fourteen chemistry-climate models. There is general agreement among the models at the broadest levels, showing column ozone decreasing at all latitudes from 1960 to around 2000, then increasing at all latitudes over the first half of the 21st century, and latitudinal variations in the rate of increase and date of return to historical values. In the second half of the century, ozone is projected to continue increasing, level off or even decrease depending on the latitude, resulting in variable dates of return to historical values at latitudes where column ozone has declined below those levels. Separation into partial column above and below 20 hPa reveals that these latitudinal differences are almost completely due to differences in the lower stratosphere. At all latitudes, upper stratospheric ozone increases throughout the 21st century and returns to 1960 levels before the end of the century, although there is a spread among the models in dates that ozone returns to historical values. Using multiple linear regression, we find decreasing halogens and increasing greenhouse gases contribute almost equally to increases in the upper stratospheric ozone. In the tropical lower stratosphere an increase in tropical upwelling causes a steady decrease in ozone through the 21st century, and total column ozone does not return to 1960 levels in all models. In contrast, lower stratospheric and total column ozone in middle and high latitudes increases during the 21st century and returns to 1960 levels.

    Lee Chuo Hiong

    2013-09-01

    Full Text Available The main objective of this study is to propose the conceptual framework for the integration of 21st century skills in biology education in Malaysia. An interdisciplinary approach for Biology, Technology, Engineering and Mathematics (BTEM is suggested to imbibe 21st century skills into the existing Biology curriculum. Solving complex and interdisciplinary worldwide biology problems will require students to understand what connections exist across disciplines and how to make those connections. BTEM allows students to master biological knowledge and at the same time to be adroit in other sub disciplinary skills. The main teaching and learning strategies that apply in the BTEM subjects are problem-based learning and inquiry-based learning which require the coordination of both knowledge and skills simultaneously. This is intended to enhance the students’ abilities to construct their own knowledge through the relevant hands-on and minds-on activities. The essence of engineering is production of design for the inventive problem solving. Integrating advanced information communication technologies such as e-tools and World Wide Web resources are believed to be able to fulfil the learning style needs of the current ‘Net Generation’. Mathematics plays an important role providing computational tools for biology and engineering, especially in analysing data. The expected outcomes of BTEM implementation are the inculcation of 21st century skills digital literacy, inventive thinking, effective communication, high productivity, spiritual and noble values in Malaysian students.

    Challenges and corresponding strategies for Chinas petroleum refining industry in 21st century were described in this paper. Entering 21st century, many countries put more concerns on environmental protection and the possibility of continual development. Production of clean fuel with low sulfur, low olefin and low aromatics to reduce toxic material emission, clean production and free-toxic emission and development of environmental friendly products and technologies will be the main themes of worlds refining industry. The challenges faced by Chinas petroleum refining industry are those from inadequate crude sources, from plant scale and its economic benefit, from processing configuration and product structure, from inferior crude and high quality products and from environmental protection and sustaining development, etc. As long as china recognizes the development trend of overall refining technology and carry out long term strategy for technological innovation and progress, its petroleum refining industry will definitely undergo a greater development and become more capable in market competition in the 21st century.

  1. Maintaining competence in radiological protection in emergency situations - a challenge for the 21st century

    International Nuclear Information System (INIS)

    Full text: State of the art radiological protection in emergency situations requires specific resources and competence in a variety of scientific and technical areas. These include e.g. nuclear and reactor physics, metrology, health sciences, radiobiology, food production, waste management, and information technology. In many of these areas a high technical standard is currently available. This standard is based on great efforts of governments, universities/research institutions and the nuclear industry during the second half of the 20th century. Although the number of scientists and technicians in these areas may appear to be sufficient today at least in some countries, there are strong indicators that future expertise is at risk. The indicators are declining university enrolment, dilution of university course content, high retirement expectations of staff members with little or no replacement planned. During the last decade many international organizations have analyzed the current situation and identified risk areas. Many proposals of general nature are available to take appropriate steps to maintain competence in the 21st century. These proposals include the following recommendations for governments, for the industry, and for international and supra-national organisations. Governments are encouraged to engage in long term strategic planning and funding to maintain competence; organize networks of collaboration between specialised organisations to maintain critical groups size; take responsibility for ensuring that human resources are available to meet obligations; support 'educational networks' among universities, research institutions, and the industry; provide scholarships, fellowships, and traineeships as part of their funding policy. The industry is encouraged to maintain high level training and in house education to meet their specific needs; develop research programmes which are attractive for students and employees; improve co-operation with universities

    Based on 150-year simulations of a regional climate model, RegCM3, under the Special Report on Emissions Scenarios (SRES) A1B scenario, the effective drought index (EDI) is used to project the future drought change in China. During the baseline period 1986–2005, RegCM3 was found to reliably simulate the spatial pattern of drought over the country. Over the 21st century, the regionally averaged EDI should increase, corresponding to a decrease of drought, while the probability of extreme drought events should increase. Geographically, drought should clearly increase in Northeast China, the middle and lower reaches of the Yangtze River valley, Southwest China, and southern Tibet but decrease in most parts of the rest of the country.

    Miller, Robert D.

    This research was conducted to study the development of 21st century communication, collaboration, and digital literacy skills of students at the high school level through the use of online social network tools. The importance of this study was based on evidence high school and college students are not graduating with the requisite skills of communication, collaboration, and digital literacy skills yet employers see these skills important to the success of their employees. The challenge addressed through this study was how high schools can integrate social network tools into traditional learning environments to foster the development of these 21st century skills. A qualitative research study was completed through the use of case study. One high school class in a suburban high performing town in Connecticut was selected as the research site and the sample population of eleven student participants engaged in two sets of interviews and learned through the use social network tools for one semester of the school year. The primary social network tools used were Facebook, Diigo, Google Sites, Google Docs, and Twitter. The data collected and analyzed partially supported the transfer of the theory of connectivism at the high school level. The students actively engaged in collaborative learning and research. Key results indicated a heightened engagement in learning, the development of collaborative learning and research skills, and a greater understanding of how to use social network tools for effective public communication. The use of social network tools with high school students was a positive experience that led to an increased awareness of the students as to the benefits social network tools have as a learning tool. The data supported the continued use of social network tools to develop 21st century communication, collaboration, and digital literacy skills. Future research in this area may explore emerging social network tools as well as the long term impact these tools

    Full Text Available According to (P21, Partnership for 21st Century Skills (n.d., unless the gap is bridged between how students learn and how they live, today’s education system will face irrelevance. The way people work and live has been transformed by demographic, economic, political, technological, and informational forces. Schools must adapt to these changing conditions in order to thrive. Students must be equipped to live in a multifaceted, multitasking, technology-driven world. And, regardless of their economic background, we must also ensure that all students have equal access to this new technological world. Collaborative learning theory which is connected to constructivism pedagogy requires students to work together to solve problems. Students need lifelong learning skills i.e., communication and information skills, problem-solving and thinking skills, and interpersonal and self-directional skills. The challenge becomes to deliberately incorporate learning skills into classrooms strategically and broadly. In this digital age, students must learn to use tools essential to everyday life and workplace productivity. They live in a world of almost unlimited streams of profound information, difficult choices and enormous opportunity. Teachers can create a 21st century context for learning by taking students out into the world, by bringing the world into the classroom, and by creating opportunities for students to collaboratively interact with each other (Learning for the, n.d..

    de Leon, Jose

    2013-09-01

    During the development of the DSM-5, even the lay press questioned psychiatr's scientific validity. This review provides 21st century psychiatry residents with ways of answering these attacks by defining the concepts and history of psychiatry (a branch of medicine), medicine and science. Psychiatric language has two levels: first, describing symptoms and signs (19th century descriptive psychopathology developed in France and Germany), and second, describing disorders (psychiatric nosology was developed in the early 20th century by Kraepelin and resuscitated by the US neo-Kraepelinian revolution leading to the DSM-III). Science is a complex trial-and-error historical process that can be threatened by those who believe too much in it and disregard its limitations. The most important psychiatric advances, electroconvulsive therapy and major psychopharmacological agents, were discovered by "chance", not by scientific planning. Jaspers's General Psychopathology is a complex 100-year-old book that describes: 1) psychiatric disorders as heterogeneous and 2) psychiatry as a hybrid scientific discipline requiring a combination of understanding (a social science method) and explanation (a natural science method). In the 21st century Berrios reminds us of psychiatry's unfortunate methodological issues due to hybrid symptoms and disorders, some of which are better understood as problems in communication between interacting human beings; in those situations neuroscience methods such as brain imaging make no sense. A new language is needed in psychiatry. East Asian psychiatry residents, who are not particularly attached to the antiquated language currently used, may be particularly equipped for the task of recreating psychiatric language using 21st century knowledge.

    Full Text Available In this paper I will analyze economic and political migration in the Gora region at the end of the 20th and in the first decade of the 21st century. It is my intent to consider and explain their cause and their intensity and scope. In short, I view the socioeconomic and political dimension of these migrations from an ethnological and anthropological point of view. The economic and political migrations from the Gora region at the end of the 20th and the beginning of the 21st century represent the continuation of earlier migrations, albeit more intensive and larger in scope (whole families are migrating. There migrations can be viewed as the effects of political changes in Kosovo, as well as the socioeconomic crisis of the 1990’s. There are no fixed boundaries between these types of migrations, and the only truly stand out examples are the cases in which people migrated for safety reasons. A certain type of migration can be identified based on the terminology used by the interlocutors. I have encountered the terms “banishment” and “displacement” in the narrative discourse of my interlocutors. These terms are used to describe the migrations from Gora during the 1999 war, as well as immediately after. The differences between economic and political migrants can be gouged from other factors such as going to Gora during vacations and holidays as well as investing money into real-estate in the region. Individuals who emigrated from Gora because they feared for their and the loves of their families go to Gora rarely (to attend funerals for example and are not currently thinking of investing unlike those who had left Gora as economic migrants. There are no differences when it comes to where people migrate to for different reasons. Places of migration can, however, be indicative of the form of migration in the sense of whether people migrated to a foreign country or not. One can turn into the other due to the changing of state borders. Thus

    A large and growing proportion of the organizations in the contemporary knowledge economy are organized as professional partnerships as is the case of professional service firms (PSFs). As these firms have grown larger (e. g. Big4: Deloitte, PwC, E&Y, KPMG), the way of organizing is under pressure...... for change. This raises the question of whether the Partner ownership and management model is a relic of the past - and the partner a Don Quixote-figure of the 21st century corporate world? Based on an ethnographic study of a PSF in Denmark, and data from other sources, the paper analyzes the changing...

    Grassland degeneration is a prominent problem in China. More in-depth studies should be carried out on the key problem--grassland degeneration for Chinese grassland ecologists in the early 21st century. Some hot research fields were restoration ecology, interface ecology, grazing ecology, health diagnoses and evaluation for grasslands. Among them, restoration ecology was the foundation for restoring degenerative grasslands; interface ecology involved with the point of contact for analyzing degenerative grasslands; grazing ecology was the effective way to control degenerative grasslands; diagnoses of grassland health benefited accurately appraising degenerative levels of grasslands; and evaluation for grassland was also considered as an estimation on services and benefits of grassland ecosystems.

    Acute pancreatitis is an acute inflammatory disease of the pancreas which can lead to a systemic inflammatory response syndrome with significant morbidity and mortality in 20% of patients. Gallstones and alcohol consumption are the most frequent causes of pancreatitis in adults. The treatment of mild acute pancreatitis is conservative and supportive; however severe episodes characterized by necrosis of the pancreatic tissue may require surgical intervention. Advanced understanding of the pathology, and increased interest in assessment of disease severity are the cornerstones of future management strategies of this complex and heterogeneous disease in the 21st century.

    Reliable estimates of future climate change in the Alps are relevant for large parts of the European society. At the same time, the complex Alpine region poses considerable challenges to climate models, which translate to uncertainties in the climate projections. Against this background, the present study reviews the state-of-knowledge about 21st century climate change in the Alps based on existing literature and additional analyses. In particular, it explicitly considers the reliability and uncertainty of climate projections. Results show that besides Alpine temperatures, also precipitation, global radiation, relative humidity, and closely related impacts like floods, droughts, snow cover, and natural hazards will be affected by global warming. Under the A1B emission scenario, about 0.25 °C warming per decade until the mid of the 21st century and accelerated 0.36 °C warming per decade in the second half of the century is expected. Warming will probably be associated with changes in the seasonality of precipitation, global radiation, and relative humidity, and more intense precipitation extremes and flooding potential in the colder part of the year. The conditions of currently record breaking warm or hot winter or summer seasons, respectively, may become normal at the end of the 21st century, and there is indication for droughts to become more severe in the future. Snow cover is expected to drastically decrease below 1500–2000 m and natural hazards related to glacier and permafrost retreat are expected to become more frequent. Such changes in climatic parameters and related quantities will have considerable impact on ecosystems and society and will challenge their adaptive capabilities. - Highlights: • Warming is expected to accelerate throughout the 21st century in the Alpine region. • Seasonal shifts in precipitation, global radiation, and relative humidity are expected. • Precipitation and temperature extremes are expected to intensify. • Snow cover

    With the advances in e-Sciences and the growing complexity of scientific analyses, more and more scientists and researchers are relying on workflow systems for process coordination, derivation automation, provenance tracking, and bookkeeping. While workflow systems have been in use for decades, it is unclear whether scientific workflows can or even should build on existing workflow technologies, or they require fundamentally new approaches. In this paper, we analyze the status and challenges of scientific workflows, investigate both existing technologies and emerging languages, platforms and systems, and identify the key challenges that must be addressed by workflow systems for e-science in the 21st century.

  4. Energy strategy of the 21st century taking advantage of fusion

    International Nuclear Information System (INIS)

    There is some general concern that economic development in developing countries will hasten global warning. In terms of reducing CO2 emissions, fusion will have great potential as a primary energy in the late 21st century according to the results of WING model simulations based on scenario analysis, if the cost of fusion with hydrogen generation would become competitive compared with those of other substitutive energies. However, securing social acceptance is very important to maintain the fossil research funded by the government suffering from cumulative debt. (author)

    Vancomycin-resistant enterococci are serious health threats due in part to their ability to persist in rugged environments and their propensity to acquire antibiotic resistance determinants. Enterococci have now established a home in our hospitals and possess mechanisms to defeat most currently available antimicrobials. This article reviews the history of the struggle with this pathogen, what is known about the traits associated with its rise in the modern medical environment, and the current understanding of therapeutic approaches in severe infections caused by these microorganisms. As the 21st century progresses, vancomycin-resistant enterococci continue to pose a daunting clinical challenge. PMID:27208766

    Market transformations occurring within the health care industry require new patterns of organization and management to meet the increasing complexity of service delivery. A greater understanding of the innovation and entrepreneurial dynamic allows administrators, managers, and leaders to create a new vision of service delivery. Central management and leadership objectives include the development of service technologies that capitalize upon the inherent knowledge of workers to meet consumer needs. A strong sense of innovation and entrepreneurship leading to the introduction of new or improved nursing technologies is a primary component in the evolution of professional nursing practice for the 21st century.

    @@ The world is in various stages of social, economic, and demographic transition. Economically and politically, the world has changed more rapidly in the past few years than at any time since 1945. The emerging global economy is both competitive and interdependent. It reflects the availability of modern communications and production technologies in most parts of the world. So, do we need to be concerned about the future of the English language in the 21st century? According to The Economist (1996), English continues to be the world standard language, and there is no major threat to the language or to its global popularity. But, changes are coming.

    As the world enters the 21st Century, policy makers around the world are grappling with issues related to energy security, energy poverty, global climate change, and the need to reduce greenhouse gas emissions while meeting an expected increase in demand for all energy sources. As a clean burning fuel, many policy leaders have suggested that LNG can play an important role as the world struggles to develop a more environmental sustainable energy future. Others claim that the safety and environmental impact of LNG, including life-cycle emissions, may nullify any clean burning benefit LNG might otherwise provide.

    After the entrance of the 21st century, Thailand's army has played a less important role in its country's politics. The changes are due to two factors. One is the external one in which social and political environment in the international politics have changed and the other is the army's own structure. Those two factors directly affect its role in the country's politics,thus preventing itself from ruling the country.

    To provide sufficient food and fiber to the increasing global population, the technologies associated with crop protection are growing ever more sophisticated but, at the same time, societal expectations for the safe use of crop protection chemistry tools are also increasing. The goal of this perspective is to highlight the key issues that face future leaders in crop protection, based on presentations made during a symposium titled "Developing Global Leaders for Research, Regulation and Stewardship of Crop Protection Chemistry in the 21st Century", held in conjunction with the IUPAC 13th International Congress of Pesticide Chemistry in San Francisco, CA, USA, during August 2014. The presentations highlighted the fact that leaders in crop protection must have a good basic scientific training and understand new and evolving technologies, are aware of the needs of both developed and developing countries, and have good communication skills. Concern is expressed over the apparent lack of resources to meet these needs, and ideas are put forward to remedy these deficiencies. PMID:25855233

    Full Text Available On the basis of his own previous research the author examines views of Europe held by the Serbian political and cultural elite in the late 20th and early 21st century. Unable to meet the challenges of the historical moment, this elite has brought Serbia into open conflict with its closest neighbors and exposed its citizens to international sanctions. War-mongering propaganda of the major state-controlled media was developing feelings of xenophobia and frustration among citizens. The collusion between authoritarian government and war profiteers was systematically destroying the lives of Serbian citizens, bringing them to the brink of material impoverishment and spiritual misery. The process of dissolution of the common Yugoslav state is coming to its end in the first decade of this century. Just as it lacked wisdom political will or strength to prevent armed conflicts and crimes, the Serbian elite today is unable to condemn war crimes, to face disastrous consequences of its own policies, and to help Serbian citizens find their way to prosperity.

    Trying to anticipate the future of tourism may be a particularly fraught task. However, this does not mean that trying to predict the future of tourism is not without value. From a business perspective, examining the future enables firms to anticipate new business conditions and develop new strategies. From a destination perspective, reflections on the future enable consideration of how to maintain or improve the qualities of a destination. The paper is focused on an analysis of the impacts of the energy and ecological macro environments on tourism trends in 21st century. Mass international tourism has thrived on the abundant and cheap supply of energy, and this may be about to change as the world moves towards 'Peak Oil'. The resultant scarcity and high price of all energy fuels will produce changes in human activities, specifically in tourism. The basis of the health of the economy is the health of the environment. Therefore issues of global environmental changes are increasingly influencing consideration of trends in tourism. In this looming transitional era tourism needs to make some dramatic changes to harmonize with the new realities of a post-energy world affected additionaly by global warming and other environmental changes.

  17. Excellence in Radiation Research for the 21st Century (EIRR21): Description of an Innovative Research Training Program

    International Nuclear Information System (INIS)

    Purpose: To describe and assess an interdisciplinary research training program for graduate students, postdoctoral fellows, and clinical fellows focused on radiation medicine; funded by the Canadian Institutes for Health Research since 2003, the program entitled “Excellence in Radiation Research for the 21st Century” (EIRR21) aims to train the next generation of interdisciplinary radiation medicine researchers. Methods and Materials: Online surveys evaluating EIRR21 were sent to trainees (n=56), mentors (n=36), and seminar speakers (n=72). Face-to-face interviews were also conducted for trainee liaisons (n=4) and participants in the international exchange program (n=2). Results: Overall response rates ranged from 53% (mentors) to 91% (trainees). EIRR21 was well received by trainees, with the acquisition of several important skills related to their research endeavors. An innovative seminar series, entitled Brainstorm sessions, imparting “extracurricular” knowledge in intellectual property protection, commercialization strategies, and effective communication, was considered to be the most valuable component of the program. Networking with researchers in other disciplines was also facilitated owing to program participation. Conclusions: EIRR21 is an innovative training program that positively impacts the biomedical community and imparts valuable skill sets to foster success for the future generation of radiation medicine researchers.

    Grasslands across the United States play a key role in regional livelihood and national food security. Yet, it is still unclear how this important resource will respond to the prolonged warm droughts and more intense rainfall events predicted with climate change. The early 21st-century drought in the southwestern United States resulted in hydroclimatic conditions that are similar to those expected with future climate change. We investigated the impact of the early 21st-century drought on aboveground net primary production (ANPP) of six desert and plains grasslands dominated by C4 (warm season) grasses in terms of significant deviations between observed and expected ANPP. In desert grasslands, drought-induced grass mortality led to shifts in the functional response to annual total precipitation (P(T)), and in some cases, new species assemblages occurred that included invasive species. In contrast, the ANPP in plains grasslands exhibited a strong linear function of the current-year P(T) and the previous-year ANPP, despite prolonged warm drought. We used these results to disentangle the impacts of interannual total precipitation, intra-annual precipitation patterns, and grassland abundance on ANPP, and thus generalize the functional response of C4 grasslands to predicted climate change. This will allow managers to plan for predictable shifts in resources associated with climate change related to fire risk, loss of forage, and ecosystem services.

    All chemistry-climate models predict that 1) the TTL warms during the 21st century and 2) that the humidity of air entering the stratosphere increases over this same period. It seems reasonable to conclude that the former causes the latter, but to our knowledge no one has actually tested that. We do so here by analyzing one chemistry-climate model in detail (the Goddard Earth Observing System Chemistry Climate Model, GEOSCCM) and find that the warming of the TTL explains only a fraction of the increase in humidity of air entering the stratosphere. We do this by using meteorological fields from the model to drive a trajectory model, which estimates the water vapor variations in response to the large-scale temperature field. Water vapor simulated by the trajectory model increases by about one quarter of the amount it increases in the GEOSCCM. We conclude that, over the 21st century, an increase in the flux of ice through the TTL is responsible for most of the increase in the humidity of air entering the stratosphere in this model.

    Based on the simulations from CMIP5 models, using climate indices which have high correlation with historical disaster data, and in combination with terrain elevation data and the socio-economic data, to project the flooding disaster risk, the vulnerability of flooding hazard affected body and the risk of flooding hazard respectively during the near term(2015-2039), medium term(2045-2069) and long term(2075-2099) under RCP8.5. According to the IPCC AR5 WGII, we used risk evaluation model of disaster: R=E*H*V. R on behalf of disaster risk index. H, E and V express risk, exposure and vulnerability respectively. The results show that the extreme flooding disaster risk will gradually increase during different terms in the future, and regions with high risk level of flooding hazard are might mainly located in southeastern and eastern China. Under the RCP8.5 greenhouse gas emissions scenario, the high risk of flooding disaster in future might mainly appear in eastern part of Sichuan, most of North China, and major of East China. Compared with the baseline period,21st century forward, although the occurrence of floods area changes little, the regional strong risk will increase during the end of the 21st century. Due to the coarse resolution of climate models and the methodology for determining weight coefficients, large uncertainty still exists in the projection of the flooding disaster risk.

    Increasing greenhouse gases and likely ozone recovery will be the two most important factors influencing changes in stratospheric temperatures in the 21st century. The radiative effect of increasing greenhouse gases will cause cooling in the stratosphere, while ozone recovery will lead to stratospheric warming. To investigate how stratospheric temperatures change under the two opposite forcings in the 21st century, we use observed ozone and reanalysis data as well as simulation results from four coupled oceanic and atmospheric general circulation models (GISS-ER, GFDL-CM20, NCAR-CCSM3, and UKMO-HadCM3) used in the IPCC (Intergovernment Panel for Climate Change) Fourth Assessment Report (AR4). Observational analysis shows that total column ozone and lower stratospheric temperatures all show increasing in the past 10 years, while middle stratospheric temperatures demonstrate cooling. IPCC AR4 simulations show that greenhouse forcing alone will lead to stratospheric cooling. However, with forcing of both increasing greenhouse gases and ozone recovery, the middle stratosphere will be cooled, while the lower stratosphere will be warmed. Warming magnitudes vary from one model to another. UKMO-HadCM3 generates relatively strong warming for all three greenhouse scenarios, and warming extends to 40 hPa. GFDL-CM20 and NCAR-CCSM3 produce weak warming, and warming mainly exists at lower levels, below about 60 hPa. In addition, we also discuss the effect of temperature changes on ozone recovery.

    Full Text Available The transformation of technology in the 21st century has produced children who are technology savvy and exposed to the internet and social networking at a very young age. These children are already in our school system. Thus teachers too need to use technology and transform the learning environment to meet the requirements of these children. This article discusses the need for transforming the primary school science teaching environment so that school children could have meaningful learning using tools familiar to them. However, while some parts of Malaysia are developing very rapidly, others are not developing as rapidly. School children in some areas are just as contented to share a single desktop computer without the Internet for a lesson. Thus teachers need to be creative to transform and improvise the learning environment to meet the pupils’ needs. This article discusses a case study on seven excellent teachers of primary school science from different parts of Malaysia. The findings of the study indicated that the excellent teachers have improvised their teachings and teaching environment to meet the needs of their pupils and the curriculum for 21st century learning.

  5. Can renewable and unconventional energy sources bridge the global energy gap in the 21st century?

    International Nuclear Information System (INIS)

    Energy experts project that global oil supplies will only meet demand until global oil production has peaked sometime between 2013 and 2020. Declining oil production after peak production will cause a global energy gap to develop, which will have to be bridged by unconventional and renewable energy sources. Nuclear, solar and hydrogen are destined to become major energy sources during the 21st century, but only if their enabling technologies improve significantly to ensure affordability and convenience of use. This paper will argue that global oil production will probably peak between 2004 and 2005, causing a serious energy gap to develop sometime between 2008 and 2010 rather than 2013-2020 as the energy experts projected. It will also argue that a transition from fossil fuels to renewable energy sources is inevitable. The paper will conclude, however, that fossil fuels with a growing contribution from nuclear energy, will still be supplying the major part of the global energy needs for most, perhaps all, of the 21st century.

  6. Prospects of Nuclear Energy in Korea in the 21st Century

    International Nuclear Information System (INIS)

    This paper tries to project the prospects of the role of nuclear energy in Korea in the 21st century. The current status of energy situations and the future prospect of nuclear energy is reviewed, and the potential of its better production and more extensive utilization is investigated. The current government policy as well as the role of nuclear industries is reviewed and a systematic approach is suggested to materialize this anticipation. Through an evaluation of the current status of domestic and foreign technologies, the general outlook of advanced nuclear energy concepts is the future is presented by identifying underdeveloped areas and suggesting a scheme of technology development. However, the present study, by nature is limited to present a general vision of the role of nuclear energy in 2000's, which should be followed by a series of detailed studies in each respective field for implementation. As Korea opens new era of mature nuclear technology, the anticipation of effective, economic, and wide production and utilization of nuclear energy in the 21st century is expected

    The name "21 st Century Laboratory" is an emerging concept of how NASA (and the world) will conduct research in the very near future. Our approach is to carefully plan for significant technological changes in products, organization, and society. The NASA mission can be the beneficiary of these changes, provided the Agency prepares for the role of 21st Century laboratories in research and technology development and its deployment in this new age. It has been clear for some time now that the technology revolutions, technology "mega-trends" that we are in the midst of now, all have a common element centered around advanced computational modeling of small scale physics. Whether it is nano technology, bio technology or advanced computational technology, all of these megatrends are converging on science at the very small scale where it is profoundly important to consider the quantum effects at play with physics at that scale. Whether it is the bio-technology creation of "nanites" designed to mimic our immune system or the creation of nanoscale infotechnology devices, allowing an order of magnitude increase in computational capability, all involve quantum physics that serves as the heart of these revolutionary changes.

  8. The delicate balance: Gazprom and Russia's competing and complementary roles in 21st century international relations

    Francis, David

    Since the fall of the Soviet Union, many have accused Russia of using its energy monopoly Gazprom as a foreign policy tool in Europe. Those who believe this point to three gas disputes between Russia and Ukraine, which they see as punishment for Ukraine's democratic reforms. However, this argument fails to consider Gazprom's actions in terms of its goals of a corporation. This paper shows, through qualitative research and interviews, that Gazprom has goals independent of Russian foreign policy objectives, and that the company has embraced corporate values at a time when Russia is moving away from western liberal ideals.

  10. Towards livestock disease diagnosis and control in the 21st century. Proceedings of an international symposium

    International Nuclear Information System (INIS)

    Livestock diseases remain a key constraint to livestock production in developing countries. Diseases like rinderpest, foot-and-mouth disease, brucellosis, trypanosomosis, tick borne diseases such as anaplasmosis, heartwater and East Coast fever, contagious bovine pleuropneumonia and Newcastle disease have caused great economic losses in various parts of the world. The control, and ultimate eradication where possible, of these and other diseases is important for the economies of many nations. It is for this reason that both the IAEA and the FAO have put great emphasis on the control and eradication of livestock diseases. The success of any disease control or eradication programme relies heavily on the robustness and efficacy of tile diagnosis, surveillance or seromonitoring method or methods being used. Nuclear based and related techniques such as enzyme linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) have played and continue to play a vital role in this regard. The aim of this symposium is to review existing and emerging techniques used in disease diagnosis and control and to carefully put them in context for use in developing countries in the future

    Projections of polar bear (Ursus maritimus) sea ice habitat distribution in the polar basin during the 21st century were developed to understand the consequences of anticipated sea ice reductions on polar bear populations. We used location data from satellitecollared polar bears and environmental data (e.g., bathymetry, distance to coastlines, and sea ice) collected from 1985 to 1995 to build resource selection functions (RSFs). RSFs described habitats that polar bears preferred in summer, autumn, winter, and spring. When applied to independent data from 1996 to 2006, the RSFs consistently identified habitats most frequently used by polar bears. We applied the RSFs to monthly maps of 21st-century sea ice concentration projected by 10 general circulation models (GCMs) used in the Intergovernmental Panel of Climate Change Fourth Assessment Report, under the A1B greenhouse gas forcing scenario. Despite variation in their projections, all GCMs indicated habitat losses in the polar basin during the 21st century. Losses in the highest-valued RSF habitat (optimal habitat) were greatest in the southern seas of the polar basin, especially the Chukchi and Barents seas, and least along the Arctic Ocean shores of Banks Island to northern Greenland. Mean loss of optimal polar bear habitat was greatest during summer; from an observed 1.0 million km2 in 1985-1995 (baseline) to a projected multi-model mean of 0.32 million km2 in 2090-2099 (-68% change). Projected winter losses of polar bear habitat were less: from 1.7 million km2 in 1985-1995 to 1.4 million km2 in 2090-2099 (-17% change). Habitat losses based on GCM multi-model means may be conservative; simulated rates of habitat loss during 1985-2006 from many GCMs were less than the actual observed rates of loss. Although a reduction in the total amount of optimal habitat will likely reduce polar bear populations, exact relationships between habitat losses and population demographics remain unknown. Density and energetic

    Predictions of polar bear (Ursus maritimus) habitat distribution in the Arctic polar basin during the 21st century were developed to help understand the likely consequences of anticipated sea ice reductions on polar bear populations. We used location data from satellite-collared polar bears and environmental data (e.g., bathymetry, coastlines, and sea ice) collected between 1985–1995 to build habitat use models called Resource Selection Functions (RSF). The RSFs described habitats polar bears preferred in each of four seasons: summer (ice minimum), autumn (growth), winter (ice maximum) and spring (melt). When applied to the model source data and to independent data (1996–2006), the RSFs consistently identified habitats most frequently used by polar bears. We applied the RSFs to monthly maps of 21st century sea ice concentration predicted by 10 general circulation models (GCM) described in the International Panel of Climate Change Fourth Assessment Report. The 10 GCMs we used had high concordance between their simulations of 20th century summer sea ice extent and the actual ice extent derived from passive microwave satellite observations. Predictions of the amount and rate of change in polar bear habitat varied among GCMs, but all GCMs predicted net habitat losses in the polar basin during the 21st century. Projected losses in the highest-valued RSF habitat (optimal habitat) were greatest in the peripheral seas of the polar basin, especially the Chukchi Sea and Barents Sea. Losses were least in high-latitude regions where RSFs predicted an initial increase in optimal habitat followed by a modest decline. The largest seasonal reductions in habitat were predicted for spring and summer. Average area of optimal polar bear habitat during summer in the polar basin declined from an observed 1.0 million km2 in 1985–1995 (baseline) to a projected multi-model average of 0.58 million km2 in 2045–2054 (-42% change), 0.36 million km2 in 2070–2079 (-64% change), and 0

    Full Text Available INTRODUCTION Two of the most dreaded diseases of the 21st century are cancer and HIV. It brings shiver down the spines of a treating physician because of the complexity of the diseases. One important way of doing this is serum albumin which is most commonly used. In recent years, the role of malnutrition as a predictor of survival in cancer has received considerable attention. As a result, it is reasonable to investigate whether serum albumin has utility as a prognostic indicator of cancer survival in cancer. This review summarizes all available epidemiological literature on the association between pretreatment serum albumin levels and survival in different types of cancer. Pretreatment serum albumin levels provide useful prognostic significance in cancer.

    De Sousa, Karina P; Doolan, Denise L

    2016-02-01

    Immunomics is a relatively new field of research which integrates the disciplines of immunology, genomics, proteomics, transcriptomics and bioinformatics to characterize the host-pathogen interface. Herein, we discuss how rapid advances in molecular immunology, sophisticated tools and molecular databases are facilitating in-depth exploration of the immunome. In our opinion, an immunomics-based approach presides over traditional antigen and vaccine discovery methods that have proved ineffective for highly complex pathogens such as the causative agents of malaria, tuberculosis and schistosomiasis that have evolved genetic and immunological host-parasite adaptations over time. By using an integrative multidisciplinary approach, immunomics offers enormous potential to advance 21st century antigen discovery and rational vaccine design against complex pathogens such as the Plasmodium parasite.

    2016-04-01

    During the early 21st century, we have experienced a transition period of global ocean observing system from expendable bathythermograph (XBT) to Argo. There has been decreasing of XBT observations, but significant increasing of Argo profiles in the global ocean. However, evaluation of the XBT observation system during this period has little been presented. Here, this study investigates the XBT effects on the global ocean observing system by using GFDL data assimilation model. After Argo period, the amount of heat content correction by XBT assimilation is significantly weaken especially in the upper ocean, but it remains in the deeper oceans below 700 m depth within a dynamic model system. This study also confirms that although XBT only provides temperature observations mostly in the upper 700 m of the northern hemisphere, it can affects both temperature and salinity fields of data assimilation system especially in the deep and southern oceans.

    Increased diversity exists in Anglo-Saxon countries, such as Australia, the United Kingdom, and the United States. By 2050, no single ethnic group is expected to be in a majority in the United States. Health care reform points to an urgent need for health care professionals, such as nursing, medicine, allied health, nutrition, and other interdisciplinary health care team members, to serve a multi-ethnic population by developing intercultural-global and 21st-century competencies. Nurse educators must acknowledge the need to familiarize themselves and integrate these competencies into university and continuing education programs by evaluating and reporting outcomes. All nurses can be expected to have these competencies as global citizens through local, intercultural, and global interactions and exchanges. PMID:25955423

    Wind tunnel testing methods and test technologies for the 21st century using advanced capabilities are presented. These capabilities are necessary to capture more accurate and high quality test results by eliminating the uncertainties in testing and to facilitate verification of computational tools for design. This paper discusses near term developments underway in ground testing capabilities, which will enhance the quality of information of both the test article and airstream flow details. Also discussed is a selection of new capability investments that have been made to accommodate such developments. Examples include advanced experimental methods for measuring the test gas itself; using efficient experiment methodologies, including quality assurance strategies within the test; and increasing test result information density by using extensive optical visualization together with computed flow field results. These points could be made for both major investments in existing tunnel capabilities or for entirely new capabilities.

    2010-09-01

    The simulated precipitation for the 20-th and 21-st centuries at 10 stations from the Danube middle and lower basin are analysed together with the daily pressure values at sea level from March, April, May for 42 years obtained from the four GCMs (CNRM, ECHAM5-MPI, EGMAM and IPSL). For the 20-th century the period 1958-1999 was considered and for the 21-st century 2 periods of 42 years were selected: 2009-2050 and 2051-2092 from the A1B scenario. In the pressure field, the predictors from three key zones were selected as being significant for the precipitation behavior from the Danube middle and lower basin. A nonhomogeneus hidden Markov model (NHMM) with 7 states was applied for the precipitation from 10 stations, for observations and also for each of the considered scenarios, with 3 predictors defined in the key points. The precipitation values were corrected by bias and the predictors were the same for all models, calculated from pressure values corrected by bias. After the modelling of the daily precipitation through a NHMM, a simulation was done on 100 achievements each one with 42 years and 90 days each year. In this way, the daily maximum precipitation amounts during spring from 4200 years were selected. This simulation was necessary in order to increase the statistical selection volume necessary within the modelling through distribution of the extreme values. From these precipitation simulated with NHMM for 4200 years, the maximum daily amounts during spring were selected and then modelled with a generalized distribution of the extreme values (GEV). For the modelling by generalized Pareto distribution (GPD) the daily precipitation values which exceed a certain threshold were selected. After testing several thresholds values, it was concluded that the most adequate is the 50 mm threshold for each of the 10 considered stations. Also it was made an average of the precipitation on the 10 considered stations and from the analysis of the different thresholds it

  7. Global hydrological droughts in the 21st century under a changing hydrological regime

    Directory of Open Access Journals (Sweden)

    N. Wanders

    2014-06-01

    Full Text Available Climate change very likely impacts future hydrological drought characteristics across the world. Here, we quantify the impact of climate change on future low flows and associated hydrological drought characteristics on a global scale using an alternative drought identification approach that considers adaptation to future changes in hydrological regime. The global hydrological model PCR-GLOBWB was used to simulate daily discharge at 0.5° globally for 1971–2099. The model was forced with CMIP5 climate projections taken from five GCMs and four emission scenarios (RCPs, from the Inter-Sectoral Impact Model Intercomparison Project. Drought events occur when discharge is below a threshold. The conventional variable threshold (VTM was calculated by deriving the threshold from the period 1971–2000. The transient variable threshold (VTMt is a non-stationary approach, where the threshold is based on the discharge values of the previous 30 years implying the threshold to vary every year during the 21st century. The VTMt adjusts to gradual changes in the hydrological regime as response to climate change. Results show a significant negative trend in the low flow regime over the 21st century for large parts of South America, southern Africa, Australia and the Mediterranean. In 40–52% of the world reduced low flows are projected, while increased low flows are found in the snow dominated climates. In 27% of the global area both the drought duration and the deficit volume are expected to increase when applying the VTMt. However, this area will significantly increase to 62% when the VTM is applied. The mean global area in drought, with the VTMt, remains rather constant (11.7 to 13.4%, compared to the substantial increase when the VTM is applied (11.7 to 20%. The study illustrates that an alternative drought identification that considers adaptation to an altered hydrological regime, has a substantial influence on future hydrological drought characteristics.

  8. Modeling biomass burning and related carbon emissions during the 21st century in Europe

    Migliavacca, Mirco

    2013-12-01

    In this study we present an assessment of the impact of future climate change on total fire probability, burned area, and carbon (C) emissions from fires in Europe. The analysis was performed with the Community Land Model (CLM) extended with a prognostic treatment of fires that was specifically refined and optimized for application over Europe. Simulations over the 21st century are forced by five different high-resolution Regional Climate Models under the Special Report on Emissions Scenarios A1B. Both original and bias-corrected meteorological forcings is used. Results show that the simulated C emissions over the present period are improved by using bias corrected meteorological forcing, with a reduction of the intermodel variability. In the course of the 21st century, burned area and C emissions from fires are shown to increase in Europe, in particular in the Mediterranean basins, in the Balkan regions and in Eastern Europe. However, the projected increase is lower than in other studies that did not fully account for the effect of climate on ecosystem functioning. We demonstrate that the lower sensitivity of burned area and C emissions to climate change is related to the predicted reduction of the net primary productivity, which is identified as the most important determinant of fire activity in the Mediterranean region after anthropogenic interaction. This behavior, consistent with the intermediate fire-productivity hypothesis, limits the sensitivity of future burned area and C emissions from fires on climate change, providing more conservative estimates of future fire patterns, and demonstrates the importance of coupling fire simulation with a climate driven ecosystem productivity model.

    Bellflower, Julie V.

    Any student seeking a high school diploma from the public school system in one U.S. state must pass the state's high school graduation test. In 2009, only 88% of students at one high school in the state met the basic proficiency requirements on the science portion of the test. Because improved science education has been identified as an explicit national goal, the purpose of this mixed methods study was to determine whether traditional teaching tools (notes, lecture, and textbook) or 21st century teaching tools (online tutorials, video games, YouTube, and virtual labs) lead to greater gains in students' science learning. Bruner's constructivist and Bandura's social cognitive theories served as the foundations for the study. Quantitative research questions were used to investigate the relationship between the type of teaching tools used and student learning gains. Quantitative data from students' pre and posttests were collected and analyzed using a dependent samples t-test. Qualitative data were collected through a focus group interview and participant journals. Analysis of the qualitative data included coding the data and writing a descriptive narrative to convey the findings. Results showed no statistically significant differences in students' science achievement: both types of teaching tools led to student learning gains. As a result, an action plan was developed to assist science educators in the implementation of traditional and 21st century teaching tools that can be used to improve students' science learning. Implications for positive social change included providing science educators with a specific plan of action that will enhance students' science learning, thereby increasing science scores on the state and other high stakes tests.

    A key feature of anticipated 21st century droughts in Southwest North America is the concurrence of elevated temperatures and increased aridity. Instrumental records and paleoclimatic evidence for past prolonged drought in the Southwest that coincide with elevated temperatures can be assessed to provide insights on temperature-drought relations and to develop worst-case scenarios for the future. In particular, during the medieval period, ∼AD 900-1300, the Northern Hemisphere experienced temperatures warmer than all but the most recent decades. Paleoclimatic and model data indicate increased temperatures in western North America of approximately 1 °C over the long-term mean. This was a period of extensive and persistent aridity over western North America. Paleoclimatic evidence suggests drought in the mid-12th century far exceeded the severity, duration, and extent of subsequent droughts. The driest decade of this drought was anomalously warm, though not as warm as the late 20th and early 21st centuries. The convergence of prolonged warming and arid conditions suggests the mid-12th century may serve as a conservative analogue for severe droughts that might occur in the future. The severity, extent, and persistence of the 12th century drought that occurred under natural climate variability, have important implications for water resource management. The causes of past and future drought will not be identical but warm droughts, inferred from paleoclimatic records, demonstrate the plausibility of extensive, severe droughts, provide a long-term perspective on the ongoing drought conditions in the Southwest, and suggest the need for regional sustainability planning for the future.

  11. Snow Cover on the Arctic Sea Ice: Model Validation, Sensitivity, and 21st Century Projections

    Blazey, Benjamin Andrew

    The role of snow cover in controlling Arctic Ocean sea ice thickness and extent is assessed with a series of models. Investigations with the stand alone Community Ice CodE (CICE) show, first, a reduction in snow depth triggers a decrease in ice volume and area, and, second, that the impact of increased snow is heavily dependent on ice and atmospheric conditions. Hindcast snow depths on the Arctic ice, simulated by the fully coupled Community Climate System Model (CCSM) are validated with 20th century in situ snow depth measurements. The snow depths in CCSM are found to be deeper than observed, likely due to excessive precipitation produced by the component atmosphere model. The sensitivity of the ice to the thermal barrier imposed by the biased snow depth is assessed. The removal of the thermodynamic impact of the exaggerated snow depth increases ice area and volume. The initial increases in ice due to enhanced conductive flux triggers feedback mechanisms with the atmosphere and ocean, reinforcing the increase in ice. Finally, the 21st century projections of decreased Arctic Ocean snow depth in CCSM are reported and diagnosed. The changes in snow are dominated by reduced accumulation due to the lack of autumn ice cover. Without this platform, much of the early snowfall is lost directly to the ocean. While this decrease in snow results in enhanced conductive flux through the ice as in the validation sensitivity experiment, the decreased summer albedo is found to dominate, as in the CICE stand alone sensitivity experiment. As such, the decrease in snow projected by CCSM in the 21st century presents a mechanism to continued ice loss. These negative (ice growth due decreased insulation) and positive (ice melt due to decreased albedo) feedback mechanisms highlight the need for an accurate representation snow cover on the ice in order to accurately simulate the evolution of Arctic Ocean sea ice.

  12. The physical drivers of historical and 21st century global precipitation changes

    International Nuclear Information System (INIS)

    Historical and 21st century global precipitation changes are investigated using data from the fifth Coupled Model Intercomparison Project (CMIP5) Atmosphere-Ocean-General-Circulation-Models (AOGCMs) and a simple energy-balance model. In the simple model, precipitation change in response to a given top-of-atmosphere radiative forcing is calculated as the sum of a response to the surface warming and a direct ‘adjustment’ response to the atmospheric radiative forcing. This simple model allows the adjustment in global mean precipitation to atmospheric radiative forcing from different forcing agents to be examined separately and emulates the AOGCMs well. During the historical period the AOGCMs simulate little global precipitation change despite an increase in global temperature—at the end of the historical period, global multi-model mean precipitation has increased by about 0.03 mm day−1, while the global multi-model mean surface temperature has warmed by about 1 K, both relative to the pre-industrial control means. This is because there is a large direct effect from CO2 and black carbon atmospheric forcing that opposes the increase in precipitation from surface warming. In the 21st century scenarios, the opposing effect from black carbon declines and the increase in global precipitation due to surface warming dominates. The cause of the spread between models in the global precipitation projections (which can be up to 0.25 mm day−1) is examined and found to come mainly from uncertainty in the climate sensitivity. The spatial distribution of precipitation change is found to be dominated by the response to surface warming. It is concluded that AOGCM global precipitation projections are in line with expectations based on our understanding of how the energy and water cycles are physically linked. (letters)

  13. Rising methane emissions in response to climate change in Northern Eurasia during the 21st century

    International Nuclear Information System (INIS)

    We used a biogeochemistry model, the Terrestrial Ecosystem Model (TEM), to examine the methane (CH4) exchanges between terrestrial ecosystems and the atmosphere in Northern Eurasia from 1971 to 2100. Multiple model simulations using various wetland extent datasets and climate change scenarios were conducted to assess the uncertainty of CH4 fluxes, including emissions and consumption. On the basis of these simulations we estimate the current net emissions in the region to be 20–24 Tg CH4 yr−1 (1 Tg = 1012 g), two-thirds of which are emitted during the summer. In response to climate change over the 21st century, the annual CH4 emissions in the region are projected to increase at a rate of 0.06 Tg CH4 yr−1, which is an order of magnitude greater than that of annual CH4 consumption. Further, the annual net CH4 emissions are projected to increase by 6–51% under various wetland extent datasets and climate scenarios by the end of the 21st century, relative to present conditions. Spatial patterns of net CH4 emissions were determined by wetland extent. Net CH4 emissions were dominated by wetlands within boreal forests, grasslands and wet tundra areas in the region. Correlation analyses indicated that water table depth and soil temperature were the two most important environmental controls on both CH4 emissions and consumption in the region. Our uncertainty analyses indicated that the uncertainty in wetland extent had a larger effect on future CH4 emissions than the uncertainty in future climate. This study suggests that better characterization of the spatial distribution and the natural diversity of wetlands should be a research priority for quantifying CH4 fluxes in this region.

  14. On Recovery of the Ozone Layer in the Northern Hemisphere in the 21st Century

    Time recovery of the ozone layer in the latitudinal zones of 0°-85° N, 0°-30° N, 30°-60° N and 60°-85° N in the 21st century has been evaluated. Evaluations have been made using an interactive chemical dynamical radiative two-dimensional (2-D) model of the middle atmosphere Socrates (height 0-120 km). As initial data for calculations for the first time the greenhouse gas concentration scenarios of Intergovernmental Panel on Climate Change (IPCC) RCP 4.5 and RCP 6.0 have been used. According to the scenario RCP 4.5 a stabilization of the radiative forcing must occur before the end of the twenty-first century, and according to the scenario RCP 6.0 - in the 22nd century. It has been shown that under both scenarios, the recovery of the ozone layer in the northern hemisphere (0°-85° N) can take place in 2035, and in zones of 0°-30° N, 30°-60° N and 60°-85° N does in 2020, 2030 and 2035, respectively. It has been also shown that after recovery the ozone layer will continue to grow and by the end of the 21st century will reach the stationary level exceeding undisturbed level of 1960 at 2.7% (scenario RCP 4.5) and 3.6% (scenario RCP 6.0) in zone 0°-85° N. It seems to be not smaller ecological threat than depletion of the ozone layer at the end of the twentieth century. The results obtained are in good agreement with the known literary data (see, for example, Table 3-3 in "Scientific Assessment of Ozone Depletion: 2010"), indicating that the model Socrates and "concentration" scenarios of IPCC can successfully be used for such calculations.

    We assess potential changes in crop water requirements and corresponding yields relative to the late 20th century in major crop producing regions of the world by using the Community Land Model (CLM) driven with 21st century meteorology from RCP8.5 and RCP4.5 Community Earth System Model (CESM) simulations. The RCP4.5 simulation allows us to explore the potential for averted societal impacts when compared to the RCP8.5 simulation. We consider the possibility for increased yields and improved water use efficiency under conditions of elevated atmospheric CO2 due to the CO2 fertilization effect (also known as concentration-carbon feedback). We address uncertainty in the current understanding of plant CO2 fertilization by repeating the simulations with and without the CO2 fertilization effect. Simulations without CO2 fertilization represent the radiative effect of elevated CO2 (i.e., warming) without representing the physiological effect of elevated CO2 (enhanced carbon uptake and increased water use efficiency by plants during photosynthesis). Preliminary results suggest that some plants may suffer from increasing heat and drought in much of the world without the CO2 fertilization effect. On the other hand plants (especially C3) tend to grow more with less water when models include the CO2 fertilization effect. Performing 21st century simulations with and without the CO2 fertilization effect brackets the potential range of outcomes. In this work we use the CLM crop model, which includes specific crop types that differ from the model's default plant functional types in that the crops get planted, harvested, and potentially fertilized and irrigated according to algorithms that attempt to capture human management decisions. We use an updated version of the CLM4.5 that includes cotton, rice, and sugarcane, spring wheat, spring barley, and spring rye, as well as temperate and tropical maize and soybean.

    Full Text Available Climate change very likely impacts future hydrological drought characteristics across the world. Here, we quantify the impact of climate change on future low flows and associated hydrological drought characteristics on a global scale using an alternative drought identification approach that considers adaptation to future changes in hydrological regime. The global hydrological model PCR-GLOBWB was used to simulate daily discharge at 0.5° globally for 1971–2099. The model was forced with CMIP5 climate projections taken from five global circulation models (GCMs and four emission scenarios (representative concentration pathways, RCPs, from the Inter-Sectoral Impact Model Intercomparison Project. Drought events occur when discharge is below a threshold. The conventional variable threshold (VTM was calculated by deriving the threshold from the period 1971–2000. The transient variable threshold (VTMt is a non-stationary approach, where the threshold is based on the discharge values of the previous 30 years implying the threshold to vary every year during the 21st century. The VTMt adjusts to gradual changes in the hydrological regime as response to climate change. Results show a significant negative trend in the low flow regime over the 21st century for large parts of South America, southern Africa, Australia and the Mediterranean. In 40–52% of the world reduced low flows are projected, while increased low flows are found in the snow-dominated climates. In 27% of the global area both the drought duration and the deficit volume are expected to increase when applying the VTMt. However, this area will significantly increase to 62% when the VTM is applied. The mean global area in drought, with the VTMt, remains rather constant (11.7 to 13.4%, compared to the substantial increase when the VTM is applied (11.7 to 20%. The study illustrates that an alternative drought identification that considers adaptation to an altered hydrological regime has a

    The German model is a consequent continuation of the work which has already lead to the Mesarovic-Pestel world-model and the 2nd report to the Club of Rome: The authors, members of the Institut fuer angewandte Systemforschung und Prognose (ISP) at Hanover, founded in 1975 by Professor Pestel, show the problems and challenges on the way to the 21st century on the basis of numerous model calculations. The German model consists of a number of coupled sub-models investigating the developments in the fields of population, education, economics, energy and labour market. Germany's role in the international network and its contribution to the North-South dialogue is taken into consideration. In the much-discussed energy sector, the calculations show that future requirements will probably be much lower than expected. Until the turn of the century, there will be no serious problems in energy and raw materials supply and consequently no structural changes.
