  1. A renewed right to urban life: A twenty-first century engagement with Lefebvre’s initial “cry”

    Pugalis, Lee; Giddings, Bob

    2011-01-01

    This paper is concerned with how space is socially produced and the vigorous struggles that this process entails. Critically engaging with some different readings of Henri Lefebvre’s spatial notion of the “right to the city” we contemplate its radical potency to reconstitute a renewed right to urban life. We argue that the right to the city – trialectically interpreted as a theoretical concept, call for action and cry – has substantial contemporary relevance and import, extending to spatial p...

  4. Is Comparative Literature Ready for the Twenty-First Century?

    Kushner, Eva

    2000-01-01

    In her article, "Is Comparative Literature Ready for the Twenty-First Century?" Eva Kushner observes that throughout its history, comparative literature has internalized as part of its own objectives and directives a major challenge: The need to renew its problematics and curriculums in response to the inherent diversity of literature within culture. She emphasizes that the vitality of the discipline depends on an authentic pluralism capable of resisting the dominance of unanalyzed hierarchie...

  5. Intelligence in the Twenty-First Century

    Shebarshin, Leonid V.

    2000-01-01

    The author concludes that the world will most probably remain rife with conflict even in the twenty first century and that the traditional role of intelligence will not only continue but will increase in importance. He characterizes the international situation as being "more of the same historically"; that is, the existence of several different centers of power and mutual conflicts based solely on national interests. In order to protect and promote one's national interests, sovereign states w...

  6. The twenty-first century in space

    Evans, Ben

    2015-01-01

    This final entry in the History of Human Space Exploration mini-series by Ben Evans continues with an in-depth look at the latter part of the 20th century and the start of the new millennium. Picking up where Partnership in Space left off, the story commemorating the evolution of manned space exploration unfolds in further detail. More than fifty years after Yuri Gagarin’s pioneering journey into space, Evans extends his overview of how that momentous voyage continued through the decades which followed. The Twenty-first Century in Space, the sixth book in the series, explores how the fledgling partnership between the United States and Russia in the 1990s gradually bore fruit and laid the groundwork for today’s International Space Station. The narrative follows the convergence of the Shuttle and Mir programs, together with standalone missions, including servicing the Hubble Space Telescope, many of whose technical and human lessons enabled the first efforts to build the ISS in orbit. The book also looks to...

  10. The Teaching Profession in the Twenty First Century

    Ramos Moreno, Mercedes

    2014-01-01

    We teach in the twenty-first century and, therefore, we need to understand the social, cultural and technological changes that are shaping the concept of education nowadays, its functions and the new role of teachers. This context also provides the background for new educational theories and methodologies that will impact on our teaching practice. Once we understand this framework, we need to focus on where we teach. Teaching can never be effective if the context of the school is not ta...

  11. Why the American public supports twenty-first century learning.

    Sacconaghi, Michele

    2006-01-01

    Aware that constituent support is essential to any educational endeavor, the AOL Time Warner Foundation (now the Time Warner Foundation), in conjunction with two respected national research firms, measured Americans' attitudes toward the implementation of twenty-first century skills. The foundation's national research survey was intended to explore public perceptions of the need for changes in the educational system, in school and after school, with respect to the teaching of twenty-first century skills. The author summarizes the findings of the survey, which were released by the foundation in June 2003. One thousand adults were surveyed by telephone, including African Americans, Latinos, teachers, and business executives. In general, the survey found that Americans believe today's students need a "basics-plus" education, meaning communication, technology, and critical thinking skills in addition to the traditional basics of reading, writing, and math. In fact, 92 percent of respondents stated that students today need different skills from those of ten to twenty years ago. Also, after-school programs were found to be an appropriate vehicle to teach these skills. Furthermore, the survey explored how well the public perceives schools to be preparing youth for the workforce and postsecondary education, which twenty-first century skills are seen as being taught effectively, and the level of need for after-school and summer programs. The survey results provide conclusive evidence of national support for basics-plus education. Thus, a clear opportunity exists to build momentum for a new model of education for the twenty-first century. PMID:17017255

  15. Accelerators for the twenty-first century a review

    Wilson, Edmund J N

    1990-01-01

    The development of the synchrotron, and later the storage ring, was based upon the electrical technology at the turn of this century, aided by the microwave radar techniques of World War II. This method of acceleration seems to have reached its limit. Even superconductivity is not likely to lead to devices that will satisfy physics needs into the twenty-first century. Unless a new principle for accelerating elementary particles is discovered soon, it is difficult to imagine that high-energy physics will continue to reach out to higher energies and luminosities.

Viewed in this perspective, the bil...

  17. Can we conquer cancer in the twenty-first century?

    Freireich, E J

    2001-08-01

    The twentieth century recorded the greatest advance in the control of human disease. From the beginning of recorded time, the human life-span changed little until the twentieth century. In the USA, it increased from 47.3 years in 1900 to 76.4 years in 2000. The answer to the question of "Can we cure cancer in the twenty-first century?" requires an appreciation of the contemporary nature of our knowledge. At the beginning of the twentieth century, major problems were nutrition and infection. By 1950, the major causes of mortality and morbidity were still infectious diseases, such as syphilis, tuberculosis, poliomyelitis, and influenza. The 1950s and 1960s were the golden age of control of infectious diseases, while cancer, because of the aging of the population and the strong association between cancer and age, has become the major healthcare problem of the twenty-first century. Until 1960, no one had proposed or demonstrated that a systemic or metastatic form of cancer could be cured. In only 35-40 years not only have techniques for the early detection, prevention, and surgical and radiation therapy treatments improved, but at least 15-20% of patients with systemic/metastatic cancers can be cured with our current primitive systemic treatments. Prior to 1943, there was no chemotherapy. Prior to 1948, no one had described complete regression of a systemic cancer. There were no multi-institution, randomized clinical trials prior to 1949. Additionally, combination chemotherapy, new drugs, bone marrow transplantation, broad-spectrum antibiotics to control infections, and platelets to control hemorrhage have been added in the past 50 years. The pace of progress extrapolates to a prediction of cancer control in the twenty-first century. The human genome has been sequenced, and it will be possible to identify expression profiles not only for malignant cells but for their normal counterparts. It is certain that interventions specific for control of the malignant

  19. Strategies for Teaching Maritime Archaeology in the Twenty First Century

    Staniforth, Mark

    2008-12-01

    Maritime archaeology is a multi-faceted discipline that requires both theoretical learning and practical skills training. In the past most universities have approached the teaching of maritime archaeology as a full-time on-campus activity designed for ‘traditional’ graduate students; primarily those in their early twenties who have recently come from full-time undergraduate study and who are able to study on-campus. The needs of mature-age and other students who work and live in different places (or countries) and therefore cannot attend lectures on a regular basis (or at all) have largely been ignored. This paper provides a case study in the teaching of maritime archaeology from Australia that, in addition to ‘traditional’ on-campus teaching, includes four main components: (1) learning field methods through field schools; (2) skills training through the AIMA/NAS avocational training program; (3) distance learning topics available through CD-ROM and using the Internet; and (4) practicums, internships and fellowships. The author argues that programs to teach maritime archaeology in the twenty first century need to be flexible and to address the diverse needs of students who do not fit the ‘traditional’ model. This involves collaborative partnerships with other universities as well as government underwater cultural heritage management agencies and museums, primarily through field schools, practicums and internships.

  5. Effect of treatment of palatal inflammatory papillary hyperplasia with local and systemic antifungal agents accompanied by renewal of complete dentures.

    Salonen, M A; Raustia, A M; Oikarinen, K S

    1996-04-01

    The aim of this study was to estimate the effect of local and systemic antifungal treatment, accompanied by renewal of complete dentures, on palatal inflammatory papillary hyperplasia (PIPH). The treatment groups consisted of 26 subjects treated with a local antifungal agent (miconazole, 2% gel) for 4 weeks and 13 subjects treated with a systemic antifungal agent (fluconazole, 50 mg) for 2 weeks (test groups). Ten subjects fitted with new complete dentures served as a control group. Variables examined before antifungal and prosthetic treatment included estimation of the size and color of the affected palatal area, measurements of the lengths of the papillae, and salivary variables. Six months after the completion of prosthetic treatment healing was determined as disappearance or marked reduction of the redness of the PIPH. Healing was more often observed in test groups (64%) than in the control group (20%) (p = 0.012). Fifty-eight per cent of the subjects treated with a local (miconazole, 2%) and 77% of those treated with a systemic (fluconazole, 50 mg) antifungal agent were healed. Even though papillary hyperplastic tissue did not disappear, the treatment of PIPH with an antifungal agent without surgery before renewal of dentures might be an alternative treatment in mild cases.

  3. Twenty-first century learning for teachers: helping educators bring new skills into the classroom.

    Wilson, John I

    2006-01-01

    The motivation behind every educator's dedication and hard work in the classroom is the knowledge that his or her teaching will result in students' success in life. Educators are committed to implementing twenty-first century skills; they have no question that students need such skills to be equipped for life beyond school. Members of the National Education Association are enthusiastic about the Partnership for 21st Century Skills framework, yet express frustration that many schools do not have adequate resources to make the necessary changes. Teaching these skills poses significant new responsibilities for schools and educators. To make it possible for teachers to build twenty-first century skills into the curriculum, physical and policy infrastructures must exist, professional development and curriculum materials must be offered, and meaningful assessments must be available. With an established understanding of what skills need to be infused into the classroom-problem solving, analysis, and com- munications-and educators' commitment to the new skill set, this chapter explores how to make such a dramatic reform happen. The author discusses existing strategies that will guide educators in infusing twenty-first century skills into traditional content areas such as math, English, geography, and science. Ultimately, public policy regarding educational standards, professional development, assessments, and physical school structures must exist to enable educators to employ twenty-first century skills, leading to student success in contemporary life. Any concern about the cost of bringing this nation's educational system up to par internationally should be offset by the price that not making twenty-first century skills a priority in the classroom will have on future economic well-being.

  4. The era of the wandering mind? Twenty-first century research on self-generated mental activity

    Felicity eCallard

    2013-12-01

    Full Text Available The first decade of the twenty-first century was characterized by renewed scientific interest in self-generated mental activity (activity largely generated by the individual, rather than in response to experimenters’ instructions or specific external sensory inputs. To understand this renewal of interest, we interrogated the peer-reviewed literature from 2003–2012 (i to explore recent changes in use of terms for self-generated mental activity; (ii to investigate changes in the topics on which mind wandering research, specifically, focuses; and (iii to visualize co-citation communities amongst researchers working on self-generated mental activity. Our analyses demonstrated that there has been a dramatic increase in the term mind wandering, and a significant crossing-over of psychological investigations of mind wandering, specifically, into cognitive neuroscience. If this is, indeed, the ‘era of the wandering mind’, our paper calls for more explicit reflection to be given by mind wandering researchers to the terms they use, the topics and brain regions they focused on, and the research literatures that they implicitly foreground or ignore as not relevant.

  5. The interrelation of twenty-first-century education and work from a gender perspective

    Kupfer , Antonia

    2014-01-01

    This paper analyses the interrelation of twenty-first-century education and work from a gender perspective. The analysis is carried out theoretically by asking whether human capital theory and Bourdieu's reproduction theory are adequate instruments for such an endeavour. It is argued that the explanatory power of the human capital concept of the interrelation between education and work is extremely weak, because the human capital concept conceals costs necessary to create human capital. In co...

    2007-01-01

    The triumph of globalization brought the emergence of a new economy. ,,The new economy” is based on the information and telecommunication technology and Internet. It is a digital economy that recognizes the fundamental role of information. That is why firms seek to change their business models in order to face the tough competition. Therefore the traditional value chain has changed. E-commerce has become a key driver of business success in the twenty first century.

  10. Twenty first century climatic and hydrological changes over Upper Indus Basin of Himalayan region of Pakistan

    This study is based on both the recent and the predicted twenty first century climatic and hydrological changes over the mountainous Upper Indus Basin (UIB), which are influenced by snow and glacier melting. Conformal-Cubic Atmospheric Model (CCAM) data for the periods 1976–2005, 2006–2035, 2041–2070, and 2071–2100 with RCP4.5 and RCP8.5; and Regional Climate Model (RegCM) data for the periods of 2041–2050 and 2071–2080 with RCP8.5 are used for climatic projection and, after bias correction, the same data are used as an input to the University of British Columbia (UBC) hydrological model for river flow projections. The projections of all of the future periods were compared with the results of 1976–2005 and with each other. Projections of future changes show a consistent increase in air temperature and precipitation. However, temperature and precipitation increase is relatively slow during 2071–2100 in contrast with 2041–2070. Northern parts are more likely to experience an increase in precipitation and temperature in comparison to the southern parts. A higher increase in temperature is projected during spring and winter over southern parts and during summer over northern parts. Moreover, the increase in minimum temperature is larger in both scenarios for all future periods. Future river flow is projected by both models to increase in the twenty first century (CCAM and RegCM) in both scenarios. However, the rate of increase is larger during the first half while it is relatively small in the second half of the twenty first century in RCP4.5. The possible reason for high river flow during the first half of the twenty first century is the large increase in temperature, which may cause faster melting of snow, while in the last half of the century there is a decreasing trend in river flow, precipitation, and temperature (2071–2100) in comparison to 2041–2070 for RCP4.5. Generally, for all future periods, the percentage of increased river flow is

  14. Report of the twenty-first session, London, 18-22 February 1991

    The Joint Group of Experts on the Scientific Aspects of Marine Pollution (GESAMP) held its twenty-first session at the Headquarters of the International Maritime Organization (IMO), London, from 18 to 22 February 1991. Marine pollution is primarily linked to coastal development. The most serious problems are those associated with inadequately controlled coastal development and intensive human settlement of the coastal zone. GESAMP emphasizes the importance of the following problems and issues: State of the marine environment; comprehensive framework for the assessment and regulation of waste disposal in the marine environment; information on preparations for the United Nations Conference on Environment and Development; review of potentially harmful substances: 1. Carcinogenic substances. 2. Mutagenic substances. 3. Teratogenic substances. 4. Organochlorine compounds. 5. Oil, and other hydrocarbons including used lubricating oils, oil spill dispersants and chemicals used in offshore oil exploration and exploitation; environmental impacts of coastal aquaculture; global change and the air/sea exchange of chemicals; future work programme

  15. Toward a Social Psychology of Race and Race Relations for the Twenty-First Century.

    Richeson, Jennifer A; Sommers, Samuel R

    2016-01-01

    The United States, like many nations, continues to experience rapid growth in its racial minority population and is projected to attain so-called majority-minority status by 2050. Along with these demographic changes, staggering racial disparities persist in health, wealth, and overall well-being. In this article, we review the social psychological literature on race and race relations, beginning with the seemingly simple question: What is race? Drawing on research from different fields, we forward a model of race as dynamic, malleable, and socially constructed, shifting across time, place, perceiver, and target. We then use classic theoretical perspectives on intergroup relations to frame and then consider new questions regarding contemporary racial dynamics. We next consider research on racial diversity, focusing on its effects during interpersonal encounters and for groups. We close by highlighting emerging topics that should top the research agenda for the social psychology of race and race relations in the twenty-first century. PMID:26361050

    McGowan, Angela K; Lee, Mary M; Meneses, Cristina M; Perkins, Jane; Youdelman, Mara

    2016-03-18

    To improve health in the twenty-first century, to promote both access to and quality of health care services and delivery, and to address significant health disparities, legal and policy approaches, specifically those focused on civil rights, could be used more intentionally and strategically. This review describes how civil rights laws, and their implementation and enforcement, help to encourage health in the United States, and it provides examples for peers around the world. The review uses a broad lens to define health for both classes of individuals and their communities-places where people live, learn, work, and play. Suggestions are offered for improving health and equity broadly, especially within societal groups and marginalized populations. These recommendations include multisectorial approaches that focus on the social determinants of health. PMID:26789383

    Full Text Available This is a broad examination of the issue of youth violence in twenty-first-century Africa, looking at the context within which a youth culture of violence has evolved and attempting to understand the underlining discourses of hegemony and power that drive it. The article focuses specifically on youth violence as apolitical response to the dynamics of (disempowerment, exclusion, and economic crisis and uses (postconflict states like Liberia, Sierra Leone, and Nigeriato explain not just the overall challenge of youth violence but also the nature of responses that it has elicited from established structures of authority. Youth violence is in many ways an expression of youth agency in the context of a social and economic system that provides little opportunity.

    Invasive alien species (IAS) threaten human livelihoods and biodiversity globally. Increasing globalization facilitates IAS arrival, and environmental changes, including climate change, facilitate IAS establishment. Here we provide the first global, spatial analysis of the terrestrial threat from IAS in light of twenty-first century globalization and environmental change, and evaluate national capacities to prevent and manage species invasions. We find that one-sixth of the global land surface is highly vulnerable to invasion, including substantial areas in developing economies and biodiversity hotspots. The dominant invasion vectors differ between high-income countries (imports, particularly of plants and pets) and low-income countries (air travel). Uniting data on the causes of introduction and establishment can improve early-warning and eradication schemes. Most countries have limited capacity to act against invasions. In particular, we reveal a clear need for proactive invasion strategies in areas with high poverty levels, high biodiversity and low historical levels of invasion. PMID:27549569

  19. Twenty-first century learning in states: the case of the Massachusetts educational system.

    Driscoll, David P

    2006-01-01

    A current crisis in education is leaving students less prepared to succeed in the working world than any generation before them. Increasingly complex external, nonacademic pressures have an impact on many of today's students, often causing them to drop out of school. Only 76 percent of Massachusetts high school students graduate, and only 29 percent earn a college degree. National figures are worse. Most educational institutions share a common goal to support students in becoming skilled, productive, successful members of society, but the author argues that this goal is not being met. Despite the constant changes in the world, educational practices have remained static. Most public schools are not adapting to meet the shifting needs of students. Universities are not able to prepare the right mix of prospective employees for the demands of the job market; for example, schools are graduating only 10 percent of the needed engineers. Institutions of higher learning cannot keep up with employers' needs in an evolving global market: strong math, science, and writing abilities; critical thinking skills; and the ability to work in teams. The author draws on exemplary efforts at work in his home state of Massachusetts--whose improvements in student achievement outcomes have been some of the best in the nation--to suggest there is promise in twenty-first century learning. Middle school students involved in a NASA-funded project write proposals, work in teams, and engage in peer review. Older students participate in enhanced, hands-on cooperative school-to-work and after-school programs. Schools are starting to offer expanded day learning, increasing the number of hours they are engaged in formal learning. Yet such programs have not reached significant levels of scale. The author calls for a major shift in education to help today's students be successful in the twenty-first century. PMID:17017262

  20. Twenty-first century learning after school: the case of Junior Achievement Worldwide.

    Box, John M

    2006-01-01

    Efforts to increase after-school programming indicate the nation's concern about how youth are engaged during out-of-school time. There are clear benefits to extending the learning that goes on during the school day. Research from the U.S. Departments of Education and Justice shows that after-school participants do better in school and have stronger expectations for the future than youth who are not occupied after school. And the need is evident: 14.3 million students return to an empty house after school, yet only 6.5 million children are currently enrolled in after-school programs. If an after-school program were available, parents of 15.3 million would enroll their child. JA Worldwide began in 1919 and has been rooted in the afterschool arena from its origins. Its after-school programs teach students about the free enterprise system through curriculum focusing on business, citizenship, economics, entrepreneurship, ethics and character, financial literacy, and career development. At the same time, JA Worldwide incorporates hands-on learning and engagement with adults as role models, both key elements to a successful after-school program. Now focused on developing curriculum emphasizing skills needed for the twenty-first century, JA adopted the key elements laid out for after-school programs by the Partnership for 21st Century Skills. To ensure that the next generation of students enters the workforce prepared, America's education system must provide the required knowledge, skills, and attitudes. Programs such as JA Worldwide serve as models of how to provide the twenty-first century skills that all students need to succeed. PMID:17017264

    The Mediterranean climate is expected to become warmer and drier during the twenty-first century. Mediterranean Sea response to climate change could be modulated by the choice of the socio-economic scenario as well as the choice of the boundary conditions mainly the Atlantic hydrography, the river runoff and the atmospheric fluxes. To assess and quantify the sensitivity of the Mediterranean Sea to the twenty-first century climate change, a set of numerical experiments was carried out with the regional ocean model NEMOMED8 set up for the Mediterranean Sea. The model is forced by air-sea fluxes derived from the regional climate model ARPEGE-Climate at a 50-km horizontal resolution. Historical simulations representing the climate of the period 1961-2000 were run to obtain a reference state. From this baseline, various sensitivity experiments were performed for the period 2001-2099, following different socio-economic scenarios based on the Special Report on Emissions Scenarios. For the A2 scenario, the main three boundary forcings (river runoff, near-Atlantic water hydrography and air-sea fluxes) were changed one by one to better identify the role of each forcing in the way the ocean responds to climate change. In two additional simulations (A1B, B1), the scenario is changed, allowing to quantify the socio-economic uncertainty. Our 6-member scenario simulations display a warming and saltening of the Mediterranean. For the 2070-2099 period compared to 1961-1990, the sea surface temperature anomalies range from +1.73 to +2.97 °C and the SSS anomalies spread from +0.48 to +0.89. In most of the cases, we found that the future Mediterranean thermohaline circulation (MTHC) tends to reach a situation similar to the eastern Mediterranean Transient. However, this response is varying depending on the chosen boundary conditions and socio-economic scenarios. Our numerical experiments suggest that the choice of the near-Atlantic surface water evolution, which is very uncertain in

    2015-05-01

    Retreat of mountain glaciers is a significant contributor to sea-level rise and a potential threat to human populations through impacts on water availability and regional hydrology. Like most of Earth’s mountain glaciers, those in western North America are experiencing rapid mass loss. Projections of future large-scale mass change are based on surface mass balance models that are open to criticism, because they ignore or greatly simplify glacier physics. Here we use a high-resolution regional glaciation model, developed by coupling physics-based ice dynamics with a surface mass balance model, to project the fate of glaciers in western Canada. We use twenty-first-century climate scenarios from an ensemble of global climate models in our simulations; the results indicate that by 2100, the volume of glacier ice in western Canada will shrink by 70 +/- 10% relative to 2005. According to our simulations, few glaciers will remain in the Interior and Rockies regions, but maritime glaciers, in particular those in northwestern British Columbia, will survive in a diminished state. We project the maximum rate of ice volume loss, corresponding to peak input of deglacial meltwater to streams and rivers, to occur around 2020-2040. Potential implications include impacts on aquatic ecosystems, agriculture, forestry, alpine tourism and water quality.

  3. Indication to Open Anatrophic Nephrolithotomy in the Twenty-First Century: A Case Report

    Alfredo Maria Bove

    2012-01-01

    Full Text Available Introduction. Advances in endourology have greatly reduced indications to open surgery in the treatment of staghorn kidney stones. Nevertheless in our experience, open surgery still represents the treatment of choice in rare cases. Case Report. A 71-year-old morbidly obese female patient complaining about occasional left flank pain, and recurrent cystitis for many years, presented bilateral staghorn kidney stones. Comorbidities were obesity (BMI 36.2, hypertension, type II diabetes, and chronic obstructive pulmunary disease (COPD hyperlipidemia. Due to these comorbidities, endoscopic and laparoscopic approaches were not indicated. We offered the patient staged open anatrophic nephrolithotomy. Results. Operative time was 180 minutes. Blood loss was 500 cc. requiring one unit of packed red blood cells. Hospital stay was 7 days. The renal function was unaffected based on preoperative and postoperative serum creatinine levels. Stone-free status of the left kidney was confirmed after surgery with CT scan. Conclusions. Open surgery can represent a valid alterative in the treatment of staghorn kidney stones of very selected cases. A discussion of the current indications in the twenty-first century is presented.

  4. Civil engineering at the crossroads in the twenty-first century.

    Ramírez, Francisco; Seco, Andres

    2012-12-01

    The twenty-first century presents a major challenge for civil engineering. The magnitude and future importance of some of the problems perceived by society are directly related to the field of the civil engineer, implying an inescapable burden of responsibility for a group whose technical soundness, rational approach and efficiency is highly valued and respected by the citizen. However, the substantial changes in society and in the way it perceives the problems that it considers important call for a thorough review of our structures, both professional and educational; so that our profession, with its undeniable historical prestige, may modernize certain approaches and attitudes in order to continue to be a reliable instrument in the service of society, giving priority from an ethical standpoint to its actions in pursuit of "the public good". It possesses important tools to facilitate this work (new technologies, the development of communications, the transmission of scientific thought.···); but there is nevertheless a need for deep reflection on the very essence of civil engineering: what we want it to be in the future, and the ability and willingness to take the lead at a time when society needs disinterested messages, technically supported, reasonably presented and dispassionately transmitted.

  5. The Third Revolution: Philosophy into Practice in Twenty-first Century Psychiatry

    KWM (Bill Fulford

    2008-12-01

    Full Text Available Three revolutions in psychiatry characterised the closing decade of the twentieth century: 1 in the neurosciences, 2 in patient-centred models of service delivery, and 3 in the emergence of a rapidly expanding new cross-disciplinary field of philosophy and psychiatry. Starting with a case history, the paper illustrates the impact of this third revolution - the new philosophy of psychiatry - on day-to-day clinical practice through training programmes and policy developments in what has become known as values-based practice. Derived from philosophical value theory and phenomenology, values-based practice is a partner to evidence-based practice in supporting clinical decision-making in the highly complex environment of mental health care. The paper concludes by setting values-based practice in context with other potentially practical important areas of the new philosophy of psychiatry arguing that all three revolutions need to be brought together if psychiatry is to meet the challenges of the twenty-first century.

    2011-12-01

    Full Text Available This study has been narrowed down to reveal a paradox. Here the vanguard of culture and civilization - which is regarded as young people of the twenty-first century – is embroiled in a discourse of exclusion: economic, political and cultural life. In secondary school programs and high schools we do not find specific references and studies, primarily based on the needs of students, about the theory of popular culture and cultural education in the area of pop culture. The paradox of exclusion of mainstream culture from educational discourse is schizophrenic. The political exclusion of young people of the XXI century I consider all the disparaging scientific discourse, which skips the actual media and communication competence of young people. Prosumers, cognitarchy, digital natives, C-generation – they are for the modern economy “Silicon Valley” - their market power to exclude is already unstoppable. In other areas it remains to be considered whether excluding young people from the cultural discourse will not deprive our future teachers and translators of the next civilization revolution of social reality...

  8. History and evolution of surgical ethics: John Gregory to the twenty-first century.

    Namm, Jukes P; Siegler, Mark; Brander, Caroline; Kim, Tae Yeon; Lowe, Christian; Angelos, Peter

    2014-07-01

    As surgery grew to become a respected medical profession in the eighteenth century, medical ethics emerged as a response to the growing need to protect patients and maintain the public's trust in physicians. The early influences of John Gregory and Thomas Percival were instrumental in the formulation of patient-centered medical ethics. In the late nineteenth century, the modern surgical advances of anesthesia and antisepsis created the need for a discipline of ethics specific to surgery in order to confront new and evolving ethical issues. One of the founding initiatives of the American College of Surgeons in 1913 was to eliminate unethical practices such as fee-splitting and itinerant surgery. As surgery continued to advance in the era of solid organ transplantation and minimally invasive surgery in the latter half of the twentieth century, surgical innovation and conflict of interest have emerged as important ethical issues moving forward into the twenty-first century. Surgical ethics has evolved into a distinct branch of medical ethics, and the core of surgical ethics is the surgeon-patient relationship and the surgeon's responsibility to advance and protect the well-being of the patient.

  9. How will melting of ice affect volcanic hazards in the twenty-first century?

    Tuffen, Hugh

    2010-05-28

    Glaciers and ice sheets on many active volcanoes are rapidly receding. There is compelling evidence that melting of ice during the last deglaciation triggered a dramatic acceleration in volcanic activity. Will melting of ice this century, which is associated with climate change, similarly affect volcanic activity and associated hazards? This paper provides a critical overview of the evidence that current melting of ice will increase the frequency or size of hazardous volcanic eruptions. Many aspects of the link between ice recession and accelerated volcanic activity remain poorly understood. Key questions include how rapidly volcanic systems react to melting of ice, whether volcanoes are sensitive to small changes in ice thickness and how recession of ice affects the generation, storage and eruption of magma at stratovolcanoes. A greater frequency of collapse events at glaciated stratovolcanoes can be expected in the near future, and there is strong potential for positive feedbacks between melting of ice and enhanced volcanism. Nonetheless, much further research is required to remove current uncertainties about the implications of climate change for volcanic hazards in the twenty-first century. PMID:20403841

    Clark, C. [Electron and Optical Physics Division, National Institute of Standards and Technology, MD (United States)]. E-mail: clark@mail.nist.gov

    2006-09-15

    Stephen Hawking's inaugural lecture as Lucasian Professor of Mathematics at Cambridge University in 1980 caused quite a stir. Its title - 'Is the end in sight for theoretical physics?' - raised the prospect of a unified 'theory of everything'. Hawking suggested that there was a good chance of resolving the remaining inconsistencies between the two big 'theories of something' - quantum mechanics and general relativity - before the turn of the century. My first impression on reading The New Physics for the Twenty-First Century, a collection of essays edited by science journalist Gordon Fraser, is that a theory of everything may still be attainable by the turn of the century. However, there is now 20 times more of everything in the universe than there was in the past century, 95% of which no-one has ever actually seen, or had even heard of until a few years ago - as summarized in articles by Wendy Freedman, Edward Kolb and Ronald Adler. Despite this, Michael Green describes amazing developments in string theory that could tie everything together, if one could just figure out which, if any, of the apparently infinite varieties of string theory applies to our world, and why.

    Ice shelves modulate Antarctic contributions to sea-level rise and thereby represent a critical, climate-sensitive interface between the Antarctic ice sheet and the global ocean. Following rapid atmospheric warming over the past decades, Antarctic Peninsula ice shelves have progressively retreated, at times catastrophically. This decay supports hypotheses of thermal limits of viability for ice shelves via surface melt forcing. Here we use a polar-adapted regional climate model and satellite observations to quantify the nonlinear relationship between surface melting and summer air temperature. Combining observations and multimodel simulations, we examine melt evolution and intensification before observed ice shelf collapse on the Antarctic Peninsula. We then assess the twenty-first-century evolution of surface melt across Antarctica under intermediate and high emissions climate scenarios. Our projections reveal a scenario-independent doubling of Antarctic-wide melt by 2050. Between 2050 and 2100, however, significant divergence in melt occurs between the two climate scenarios. Under the high emissions pathway by 2100, melt on several ice shelves approaches or surpasses intensities that have historically been associated with ice shelf collapse, at least on the northeast Antarctic Peninsula.

    It is shown in this paper that the D-He-3 fusion fuel cycle is not only credible from a physics standpoint, but that its breakeven and ignition characteristics could be developed on roughly the same time schedule as the DT cycle. It was also shown that the extremely low fraction of power in neutrons, the lack of significant radioactivity in the reactants, and the potential for very high conversion efficiencies, can result in definite advantages for the D-He-3 cycle with respect to DT fusion and fission reactors in the twenty-first century. More specifically, the D-He-3 cycle can accomplish the following: (1) eliminate the need for deep geologic waste burial facilities and the wastes can qualify for Class A, near-surface land burial; (2) allow 'inherently safe' reactors to be built that, under the worst conceivable accident, cannot cause a civilian fatality or result in a significant (greater than 100 mrem) exposure to a member of the public; (3) reduce the radiation damage levels to a point where no scheduled replacement of reactor structural components is required, i.e., full reactor lifetimes (approximately 30 FPY) can be credibly claimed; (4) increase the reliability and availability of fusion reactors compared to DT systems because of the greatly reduced radioactivity, the low neutron damage, and the elimination of T breeding; and (5) greatly reduce the capital costs of fusion power plants (compared to DT systems) by as much as 50 percent and present the potential for a significant reduction on the COE. The concepts presented in this paper tie together two of the most ambitious high-technology endeavors of the twentieth century: the development of controlled thermonuclear fusion for civilian power applications and the utilization of outer space for the benefit of mankind on Earth.

  14. Latvian Security and Defense Policy within the Twenty-First Century Security Environment

    Rublovskis Raimonds

    2014-12-01

    Full Text Available The aim of this paper is to analyze fundamental factors which form and profoundly shape security and defense policy of the Republic of Latvia. One can argue that historical background, geographical location, common institutional history within the former Soviet Union, the Russia factor, the relative smallness of the territory of state and the population, the ethnic composition of the population, the low density of the population and rather limited financial and manpower resources available for the defense of the Republic of Latvia are the key factors of influence on the state security and defense policy. The core principles of the security and defense policy of Latvia are the membership in powerful global military alliance of NATO and bilateral strategic partnership with the United States. However, security and defense cooperation among the three Baltic States as well as enhanced cooperation within the Baltic-Nordic framework is seen as an important supplementary factor for the increased security of the Republic of Latvia. Latvia has developed a sustainable legal and institutional framework in order to contribute to state security and defense; however, security challenges and significant changes within the global security environment of the twenty-first century will further challenge the ability of the Republic of Latvia to sustain its current legal framework, and more importantly, current institutional structure of Latvian security and defense architecture. Significant internal and external challenges will impact the fundamental pillars of Latvian security and defense policy, such as American strategic shift to the Pacific, and lack of political will to increase defense budgets in European part of NATO. It has to be clear that very independence, security and defense of the Republic of Latvia depend on the ability of NATO to remain an effective organization with timely and efficient decision-making, and the ability of the United States to remain

  15. Gendering inequality: a note on Piketty's Capital in the twenty-first century.

    Perrons, Diane

    2014-12-01

    Thomas Piketty's Capital in the Twenty-First Century is remarkable for moving inequality from the margins to mainstream debate through detailed analysis of longitudinal statistics and, for an economist, by advocating an interdisciplinary perspective and writing in a witty and accessible style. With reference to the post 1970 period, when wage increases are largely responsible for the increase in inequality, Piketty shows how patrimonial capitalists (elite managers) in the top decile and centile of the distribution appropriate a growing share of social wealth as a consequence of their 'power to set their own remuneration' in the context of tolerant social norms rather than through their productive contributions. Piketty raises but defers the question of where these social norms come from to other disciplines. A Feminist Economics perspective indicates that these questions are central to a more inclusive form of economic analysis and such an approach would enrich Piketty's analysis in two main ways. First, by paying greater attention to the processes and social norms through which inequalities are produced and justified and second by highlighting the ways in which inequality is experienced differently depending not only on class, but also on other aspects of identity including gender. This approach also suggests that it is necessary to supplement the ex-post redistributive policies recommended by Piketty: a global wealth tax and more steeply progressive income tax, with ex-ante measures to stop the rise in wage inequality in the first place, especially by bridging the huge gulf that exists between those who care for people and those who manage money.

  16. Yeast culture collections in the twenty-first century: new opportunities and challenges.

    Boundy-Mills, Kyria L; Glantschnig, Ewald; Roberts, Ian N; Yurkov, Andrey; Casaregola, Serge; Daniel, Heide-Marie; Groenewald, Marizeth; Turchetti, Benedetta

    The twenty-first century has brought new opportunities and challenges to yeast culture collections, whether they are long-standing or recently established. Basic functions such as archiving, characterizing and distributing yeasts continue, but with expanded responsibilities and emerging opportunities. In addition to a number of well-known, large public repositories, there are dozens of smaller public collections that differ in the range of species and strains preserved, field of emphasis and services offered. Several collections have converted their catalogues to comprehensive databases and synchronize them continuously through public services, making it easier for users worldwide to locate a suitable source for specific yeast strains and the data associated with these yeasts. In-house research such as yeast taxonomy continues to be important at culture collections. Because yeast culture collections preserve a broad diversity of species and strains within a species, they are able to make discoveries in many other areas as well, such as biotechnology, functional, comparative and evolution genomics, bioprocesses and novel products. Due to the implementation of the Convention of Biological Diversity (CBD) and the Nagoya Protocol (NP), there are new requirements for both depositors and users to ensure that yeasts were collected following proper procedures and to guarantee that the country of origin will be considered if benefits arise from a yeast's utilization. Intellectual property rights (IPRs) are extremely relevant to the current access and benefit-sharing (ABS) mechanisms; most research and development involving genetic resources and associated traditional knowledge will be subject to this topic.

  17. Strong Inference in Mathematical Modeling: A Method for Robust Science in the Twenty-First Century

    Ganusov, Vitaly V.

    2016-01-01

    While there are many opinions on what mathematical modeling in biology is, in essence, modeling is a mathematical tool, like a microscope, which allows consequences to logically follow from a set of assumptions. Only when this tool is applied appropriately, as microscope is used to look at small items, it may allow to understand importance of specific mechanisms/assumptions in biological processes. Mathematical modeling can be less useful or even misleading if used inappropriately, for example, when a microscope is used to study stars. According to some philosophers (Oreskes et al., 1994), the best use of mathematical models is not when a model is used to confirm a hypothesis but rather when a model shows inconsistency of the model (defined by a specific set of assumptions) and data. Following the principle of strong inference for experimental sciences proposed by Platt (1964), I suggest “strong inference in mathematical modeling” as an effective and robust way of using mathematical modeling to understand mechanisms driving dynamics of biological systems. The major steps of strong inference in mathematical modeling are (1) to develop multiple alternative models for the phenomenon in question; (2) to compare the models with available experimental data and to determine which of the models are not consistent with the data; (3) to determine reasons why rejected models failed to explain the data, and (4) to suggest experiments which would allow to discriminate between remaining alternative models. The use of strong inference is likely to provide better robustness of predictions of mathematical models and it should be strongly encouraged in mathematical modeling-based publications in the Twenty-First century.

  18. Fusion energy from the Moon for the twenty-first century

    It is shown in this paper that the D-He-3 fusion fuel cycle is not only credible from a physics standpoint, but that its breakeven and ignition characteristics could be developed on roughly the same time schedule as the DT cycle. It was also shown that the extremely low fraction of power in neutrons, the lack of significant radioactivity in the reactants, and the potential for very high conversion efficiencies, can result in definite advantages for the D-He-3 cycle with respect to DT fusion and fission reactors in the twenty-first century. More specifically, the D-He-3 cycle can accomplish the following: (1) eliminate the need for deep geologic waste burial facilities and the wastes can qualify for Class A, near-surface land burial; (2) allow inherently safe reactors to be built that, under the worst conceivable accident, cannot cause a civilian fatality or result in a significant (greater than 100 mrem) exposure to a member of the public; (3) reduce the radiation damage levels to a point where no scheduled replacement of reactor structural components is required, i.e., full reactor lifetimes (approximately 30 FPY) can be credibly claimed; (4) increase the reliability and availability of fusion reactors compared to DT systems because of the greatly reduced radioactivity, the low neutron damage, and the elimination of T breeding; and (5) greatly reduce the capital costs of fusion power plants (compared to DT systems) by as much as 50 percent and present the potential for a significant reduction on the COE. The concepts presented in this paper tie together two of the most ambitious high-technology endeavors of the twentieth century: the development of controlled thermonuclear fusion for civilian power applications and the utilization of outer space for the benefit of mankind on Earth

  20. Assessing twenty-first century skills through a teacher created video game for high school biology students

    Annetta, Leonard A.; Cheng, Meng-Tzu; Holmes, Shawn

    2010-07-01

    As twenty-first century skills become a greater focus in K-12 education, an infusion of technology that meets the needs of today's students is paramount. This study looks at the design and creation of a Multiplayer Educational Gaming Application (MEGA) for high school biology students. The quasi-experimental, qualitative design assessed the twenty-first century skills of digital age literacy, inventive thinking, high productivity, and effective communication techniques of the students exposed to a MEGA. Three factors, as they pertained to these skills, emerged from classroom observations. Interaction with the teacher, discussion with peers, and engagement/time-on-task while playing the MEGA suggested that students playing an educational video game exhibited all of the projected twenty-first century skills while being engrossed in the embedded science content.

  7. Science Teacher Education in the Twenty-First Century: a Pedagogical Framework for Technology-Integrated Social Constructivism

    Barak, Miri

    2016-01-01

    Changes in our global world have shifted the skill demands from acquisition of structured knowledge to mastery of skills, often referred to as twenty-first century competencies. Given these changes, a sequential explanatory mixed methods study was undertaken to (a) examine predominant instructional methods and technologies used by teacher educators, (b) identify attributes for learning and teaching in the twenty-first century, and (c) develop a pedagogical framework for promoting meaningful usage of advanced technologies. Quantitative and qualitative data were collected via an online survey, personal interviews, and written reflections with science teacher educators and student teachers. Findings indicated that teacher educators do not provide sufficient models for the promotion of reform-based practice via web 2.0 environments, such as Wikis, blogs, social networks, or other cloud technologies. Findings also indicated four attributes for teaching and learning in the twenty-first century: (a) adapting to frequent changes and uncertain situations, (b) collaborating and communicating in decentralized environments, (c) generating data and managing information, and (d) releasing control by encouraging exploration. Guided by social constructivist paradigms and twenty-first century teaching attributes, this study suggests a pedagogical framework for fostering meaningful usage of advanced technologies in science teacher education courses.

  8. Psychosocial Accompaniment

    Mary Watkins

    2015-01-01

    This essay advocates for a paradigm shift in psychology toward the activity and ethics of accompaniment. Accompaniment requires a reorientation of the subjectivity, interpersonal practices, and critical understanding of the accompanier so that (s)he can stand alongside others who desire listening, witnessing, advocacy, space to develop critical inquiry and research, and joint imagination and action to address desired and needed changes. The idea of “accompaniment” emerged in liberation theolo...

    Milanovic, Branko

    2014-01-01

    Capital in the Twenty-First Century by Thomas Piketty provides a unified theory of the functioning of the capitalist economy by linking theories of economic growth and functional and personal income distributions. It argues, based on the long-run historical data series, that the forces of economic divergence (including rising income inequality) tend to dominate in capitalism. It regards the twentieth century as an exception to this rule and proposes policies that would make capitalism sustain...

  13. Twenty-first century learning in school systems: the case of the Metropolitan School District of Lawrence Township, Indianapolis, Indiana.

    Capuano, Marcia; Knoderer, Troy

    2006-01-01

    To empower students with skills such as information and technological literacy, global awareness and cultural competence, self-direction, and sound reasoning, teachers must master these skills themselves. This chapter examines how the Digital Age Literacy Initiative of the Metropolitan School District of Lawrence Township in Indianapolis, Indiana, which is funded by the Lilly Endowment, incorporated twenty-first century learning through a systemic approach involving teacher training and the use of data. The authors explain the district's content, process, and context goals toward accomplishing its mission of empowering students with the necessary twenty-first century skills to succeed in the digital age. The district places a strong emphasis on professional development for teachers. To support the necessary teacher learning and therefore sustain the work of the initiative, the district has adopted action research, self-assessment, and an online professional development network. To support teachers in implementing new strategies, master teachers serve as digital age literacy coaches. The chapter discusses the initiative's focus on evidence of progress. Through a partnership with the Metiri Group of California, the district has built a range of assessments including online inventories and twenty-first century skill rubrics. For example, the Mankato Survey collected teacher and student data around access, ability, and use of technology in the classroom in 2001 and then in 2004. This research showed significant gains in some technologies across all grade levels and consistent gains in nearly all technologies for middle and high school students. As it moves into the next phase of implementing the Digital Age Literacy Initiative, the district embraces the systemic shifts in school culture necessary to institutionalize twenty-first century learning.

  14. Detached concern?: Emotional socialization in twenty-first century medical education.

    Underman, Kelly; Hirshfield, Laura E

    2016-07-01

    Early works in medical sociology have been pivotal in the development of scholarly knowledge about emotions, emotional socialization, and empathy within medical training, medical education, and medical contexts. Yet despite major shifts in both medical education and in medicine writ-large, medical sociologists' focus on emotions has largely disappeared. In this paper, we argue that due to recent radical transformations in the medical arena, emotional socialization within medical education should be of renewed interest for sociologists. Developments in medical education such as increased diversity among enrollees, the rise of patient health movements, and curricular transformation have made this context a particularly interesting case for sociologists working on a variety of questions related to structural, organizational, and cultural change. We offer three areas of debate within studies in medical education that sociologists may be interested in studying: 1) gendered and racialized differences in the performance of clinical skills related to emotion, 2) differences in self-reported empathy among subspecialties, and 3) loss of empathy during the third year or clinical year of medical school.

  15. Twenty-first century probabilistic projections of precipitation over Ontario, Canada through a regional climate model ensemble

    Wang, Xiuquan; Huang, Guohe; Liu, Jinliang

    2016-06-01

    In this study, probabilistic projections of precipitation for the Province of Ontario are developed through a regional climate model ensemble to help investigate how global warming would affect its local climate. The PRECIS regional climate modeling system is employed to perform ensemble simulations, driven by a set of boundary conditions from a HadCM3-based perturbed-physics ensemble. The PRECIS ensemble simulations are fed into a Bayesian hierarchical model to quantify uncertain factors affecting the resulting projections of precipitation and thus generate probabilistic precipitation changes at grid point scales. Following that, reliable precipitation projections throughout the twenty-first century are developed for the entire province by applying the probabilistic changes to the observed precipitation. The results show that the vast majority of cities in Ontario are likely to suffer positive changes in annual precipitation in 2030, 2050, and 2080 s in comparison to the baseline observations. This may suggest that the whole province is likely to gain more precipitation throughout the twenty-first century in response to global warming. The analyses on the projections of seasonal precipitation further demonstrate that the entire province is likely to receive more precipitation in winter, spring, and autumn throughout this century while summer precipitation is only likely to increase slightly in 2030 s and would decrease gradually afterwards. However, because the magnitude of projected decrease in summer precipitation is relatively small in comparison with the anticipated increases in other three seasons, the annual precipitation over Ontario is likely to suffer a progressive increase throughout the twenty-first century (by 7.0 % in 2030 s, 9.5 % in 2050 s, and 12.6 % in 2080 s). Besides, the degree of uncertainty for precipitation projections is analyzed. The results suggest that future changes in spring precipitation show higher degree of uncertainty than other

  18. A needs assessment for DOE's packaging and transportation activities - a look into the twenty-first century

    The U.S. Department of Energy (DOE) has performed a department-wide scoping of its packaging and transportation needs and has arrived at a projection of these needs for well into the twenty-first century. The assessment, known as the Transportation Needs Assessment (TNA) was initiated during August 1994 and completed in December 1994. The TNA will allow DOE to better prepare for changes in its transportation requirements in the future. The TNA focused on projected, quantified shipping needs based on forecasts of inventories of materials which will ultimately require transport by the DOE for storage, treatment and/or disposal. In addition, experts provided input on the growing needs throughout DOE resulting from changes in regulations, in DOE's mission, and in the sociopolitical structure of the United States. Through the assessment, DOE's transportation needs have been identified for a time period extending from the present through the first three decades of the twenty-first century. The needs assessment was accomplished in three phases: (1) defining current packaging, shipping, resource utilization, and methods of managing packaging and transportation activities; (2) establishing the inventory of materials which DOE will need to transport on into the next century and scenarios which project when, from where, and to where these materials will need to be transported; and (3) developing requirements and projected changes for DOE to accomplish the necessary transport safely and economically

    2016-04-01

    Most of the policy debate surrounding the actions needed to mitigate and adapt to anthropogenic climate change has been framed by observations of the past 150 years as well as climate and sea-level projections for the twenty-first century. The focus on this 250-year window, however, obscures some of the most profound problems associated with climate change. Here, we argue that the twentieth and twenty-first centuries, a period during which the overwhelming majority of human-caused carbon emissions are likely to occur, need to be placed into a long-term context that includes the past 20 millennia, when the last Ice Age ended and human civilization developed, and the next ten millennia, over which time the projected impacts of anthropogenic climate change will grow and persist. This long-term perspective illustrates that policy decisions made in the next few years to decades will have profound impacts on global climate, ecosystems and human societies -- not just for this century, but for the next ten millennia and beyond.

  20. On ‘a Continuum with Expansion’? Intelligence Cooperation in Europe in the Early Twenty-first Century

    Adam D.M. Svendsen

    2011-12-01

    Full Text Available This article argues that during the early twenty-first century, generally we have witnessed greater intelligence co-operation in Europe. Indeed, we can even appropriately discuss the increased 'regionalisation of intelligence'. Effectively reflecting 'uneven and combined development', persistently these co-operative intelligence trends appear to be occurring haphazardly, non-uniformly and at several different rates at the different levels of relations in the various 'pockets' of European intelligence co-operation. This article concludes by arguing that overall there is the development of an ever-more complex web consisting of a plethora of various overlapping international intelligence liaison arrangements that collectively provide a form of regional intelligence coverage in Europe. How they overlap is important, accounting for the connections, and notably the 'disconnects', that publicly come to our attention.

  2. Evolution and modulation of tropical heating from the last glacial maximum through the twenty-first century

    Hoyos, Carlos D.; Webster, Peter J. [Georgia Institute of Technology, School of Earth and Atmospheric Sciences, Atlanta, GA (United States)

    2012-04-15

    Twentieth century observations show that during the last 50 years the sea-surface temperature (SST) of the tropical oceans has increased by {proportional_to}0.5 C and the area of SST >26.5 and 28 C (arbitrarily referred to as the oceanic warm pool: OWP) by 15 and 50% respectively in association with an increase in green house gas concentrations, with non-understood natural variability or a combination of both. Based on CMIP3 projections the OWP is projected to double during twenty-first century in a moderate CO{sub 2} forcing scenario (IPCC A1B scenario). However, during the observational period the area of positive atmospheric heating (referred to as the dynamic warm pool, DWP), has remained constant. The threshold SST (T{sub H}), which demarks the region of net heating and cooling, has increased from 26.6 C in the 1950s to 27.1 C in the last decade and it is projected to increase to {proportional_to}28.5 C by 2100. Based on climate model simulations, the area of the DWP is projected to remain constant during the twenty-first century. Analysis of the paleoclimate model intercomparison project (PMIP I and II) simulations for the Last Glacial maximum and the Mid-Holocene periods show a very similar behaviour, with a larger OWP in periods of elevated tropical SST, and an almost constant DWP associated with a varying T{sub H}. The constancy of the DWP area, despite shifts in the background SST, is shown to be the result of a near exact matching between increases in the integrated convective heating within the DWP and the integrated radiative cooling outside the DWP as SST changes. Although the area of the DWP remains constant, the total tropical atmospheric heating is a strong function of the SST. For example the net heating has increased by about 10% from 1950 to 2000 and it is projected to increase by a further 20% by 2100. Such changes must be compensated by a more vigorous atmospheric circulation, with growth in convective heating within the warm pool, and an

  3. From Decent Work to Decent Lives: Positive Self and Relational Management (PS&RM) in the Twenty-First Century.

    Di Fabio, Annamaria; Kenny, Maureen E

    2016-01-01

    The aim of the present study is to empirically test the theoretical model, Positive Self and Relational Management (PS&RM), for a sample of 184 Italian university students. The PS&RM model specifies the development of individuals' strengths, potentials, and talents across the lifespan and with regard to the dialect of self in relationship. PS&RM is defined theoretically by three constructs: Positive Lifelong Life Management, Positive Lifelong Self-Management, Positive Lifelong Relational Management. The three constructs are operationalized as follows: Positive Lifelong Life Management is measured by the Positive and Negative Affect Schedule (PANAS), the Satisfaction With Life Scale (SWLS), the Meaningful Life Measure (MLM), and the Authenticity Scale (AS); Positive Lifelong Self-Management is measured by the Intrapreneurial Self-Capital Scale (ISC), the Career Adapt-Abilities Scale (CAAS), and the Life Project Reflexivity Scale (LPRS); and Positive Lifelong Relational Management is measured by the Trait Emotional Intelligence Questionnaire (TEIQue), the Multidimensional Scale for Perceived Social Support (MSPSS), and the Positive Relational Management Scale (PRMS). Confirmatory factor analysis of the PS&RM model was completed using structural equation modeling. The theoretical PS&RM model was empirically tested as defined by the three hypothesized constructs. Empirical support for this model offers a framework for further research and the design of preventive interventions to promote decent work and decent lives in the twenty-first century. PMID:27047406

  4. Shelter and indoor air in the twenty-first century--radon, smoking, and lung cancer risks

    Recognition that radon and its daughter products may accumulate to high levels in homes and in the workplace has led to concern about the potential lung cancer risk resulting from indoor domestic exposure. While such risks can be estimated with current dosimetric and epidemiological models for excess relative risks, it must be recognized that these models are based on data from occupational exposure and from underground miners' mortality experience. Several assumptions are required to apply risk estimates from an occupational setting to the indoor domestic environment. Analyses of the relevant data do not lead to a conclusive description of the interaction between radon daughters and cigarette smoking for the induction of lung cancer. The evidence compels the conclusion that indoor radon daughter exposure in homes represents a potential life-threatening public health hazard, particularly in males, and in cigarette smokers. Resolution of complex societal interactions will require public policy decisions involving the governmental, scientific, financial, and industrial sectors. These decisions impact the home, the workplace, and the marketplace, and they extend beyond the constraints of science. Risk identification, assessment, and management require scientific and engineering approaches to guide policy decisions to protect the public health. Mitigation and control procedures are only beginning to receive attention. Full acceptance for protection against what could prove to be a significant public health hazard in the twenty-first century will certainly involve policy decisions, not by scientists, but rather by men and women of government and law

  5. Prehistorically modified soils of central Amazonia: a model for sustainable agriculture in the twenty-first century.

    Glaser, Bruno

    2007-02-28

    Terra Preta soils of central Amazonia exhibit approximately three times more soil organic matter, nitrogen and phosphorus and 70 times more charcoal compared to adjacent infertile soils. The Terra Preta soils were generated by pre-Columbian native populations by chance or intentionally adding large amounts of charred residues (charcoal), organic wastes, excrements and bones. In this paper, it is argued that generating new Terra Preta sites ('Terra Preta nova') could be the basis for sustainable agriculture in the twenty-first century to produce food for billions of people, and could lead to attaining three Millennium Development Goals: (i) to combat desertification, (ii) to sequester atmospheric CO2 in the long term, and (iii) to maintain biodiversity hotspots such as tropical rainforests. Therefore, large-scale generation and utilization of Terra Preta soils would decrease the pressure on primary forests that are being extensively cleared for agricultural use with only limited fertility and sustainability and, hence, only providing a limited time for cropping. This would maintain biodiversity while mitigating both land degradation and climate change. However, it should not be overlooked that the infertility of most tropical soils (and associated low population density) is what could have prevented tropical forests undergoing large-scale clearance for agriculture. Increased fertility may increase the populations supported by shifting cultivation, thereby maintaining and increasing pressure on forests. PMID:17255028

    Transformational learning is the focus of twenty-first century global educational reforms. In India, there is a need to amalgamate the skills and knowledge of medical, nursing, and public health practitioners and to develop robust leadership competencies among them. This initiative proposed to identify interdisciplinary leadership competencies among Indian health practitioners and to develop a training program for interdisciplinary leadership skills through an Innovation Collaborative. Medical, nursing, and public health institutions partnered in this endeavor. An exhaustive literature search was undertaken to identify leadership competencies in these three professions. Published evidence was utilized in searching for the need for interdisciplinary training of health practitioners, including current scenarios in interprofessional health education and the key competencies required. The interdisciplinary leadership competencies identified were self-awareness, vision, self-regulation, motivation, decisiveness, integrity, interpersonal communication skills, strategic planning, team building, innovation, and being an effective change agent. Subsequently, a training program was developed, and three training sessions were piloted with 66 participants. Each cohort comprised a mix of participants from different disciplines. The pilot training guided the development of a training model for building interdisciplinary leadership skills and organizing interdisciplinary leadership workshops. The need for interdisciplinary leadership competencies is recognized. The long-term objective of the training model is integration into the regular medical, nursing, and public health curricula, with the aim of developing interdisciplinary leadership skills among them. Although challenging, formal incorporation of leadership skills into health professional education is possible within the interdisciplinary classroom setting using principles of transformative learning.

  7. Inherited Behaviour in Wilkie Collins's The Legacy of Cain: Victorian Studies and Twenty-First-Century Science Policy

    Jay Clayton

    2008-10-01

    Full Text Available 'The Legacy of Cain' (1888, the last novel Wilkie Collins published before his death, is structured as a case study of the respective influences of nature and nurture. The central question is whether the daughter of a murderess will reveal a 'hereditary taint' or whether a loving and religious environment will prove the stronger influence on the child's character. The Victorians knew nothing about genetics, but scientists and novelists alike shared a vigorous discourse about the hereditary transmission of behaviour and whether 'character' was heritable. In the wake of genetic and epigenetic discoveries, we find ourselves faced with a situation comparable to that Collins encountered in the 1880s, when evolutionary theory was unsettling many things Victorians held dear. Exploring how novelists and scientists in the late-nineteenth century attempted to cope with notions of inherited behaviour without genetics sheds an interesting light on twenty-first-century reactions to the news that acquired characteristics and behavioural traits may be passed on to future generations through mechanisms other than the gene. The emergence of an influential, semi-autonomous zone of activity known as the policy arena, which occupies an intermediate position between the disciplinary specialist and the public sphere, enables humanists to participate in science policy today in ways comparable to the contributions made by Victorian literary figures such as Wilkie Collins, George Eliot, Matthew Arnold and Samuel Butler.

  8. From Decent Work to Decent Lives: Positive Self and Relational Management (PS&RM) in the Twenty-First Century

    Di Fabio, Annamaria; Kenny, Maureen E.

    2016-01-01

    The aim of the present study is to empirically test the theoretical model, Positive Self and Relational Management (PS&RM), for a sample of 184 Italian university students. The PS&RM model specifies the development of individuals' strengths, potentials, and talents across the lifespan and with regard to the dialect of self in relationship. PS&RM is defined theoretically by three constructs: Positive Lifelong Life Management, Positive Lifelong Self-Management, Positive Lifelong Relational Management. The three constructs are operationalized as follows: Positive Lifelong Life Management is measured by the Positive and Negative Affect Schedule (PANAS), the Satisfaction With Life Scale (SWLS), the Meaningful Life Measure (MLM), and the Authenticity Scale (AS); Positive Lifelong Self-Management is measured by the Intrapreneurial Self-Capital Scale (ISC), the Career Adapt-Abilities Scale (CAAS), and the Life Project Reflexivity Scale (LPRS); and Positive Lifelong Relational Management is measured by the Trait Emotional Intelligence Questionnaire (TEIQue), the Multidimensional Scale for Perceived Social Support (MSPSS), and the Positive Relational Management Scale (PRMS). Confirmatory factor analysis of the PS&RM model was completed using structural equation modeling. The theoretical PS&RM model was empirically tested as defined by the three hypothesized constructs. Empirical support for this model offers a framework for further research and the design of preventive interventions to promote decent work and decent lives in the twenty-first century. PMID:27047406

    Sea-level change is often considered to be globally uniform in sea-level projections. However, local relative sea-level (RSL) change can deviate substantially from the global mean. Here, we present maps of twenty-first century local RSL change estimates based on an ensemble of coupled climate model simulations for three emission scenarios. In the Intergovernmental Panel on Climate Change Fourth Assessment Report (IPCC AR4), the same model simulations were used for their projections of global mean sea-level rise. The contribution of the small glaciers and ice caps to local RSL change is calculated with a glacier model, based on a volume-area approach. The contributions of the Greenland and Antarctic ice sheets are obtained from IPCC AR4 estimates. The RSL distribution resulting from the land ice mass changes is then calculated by solving the sea-level equation for a rotating, elastic Earth model. Next, we add the pattern of steric RSL changes obtained from the coupled climate models and a model estimate for the effect of Glacial Isostatic Adjustment. The resulting ensemble mean RSL pattern reveals that many regions will experience RSL changes that differ substantially from the global mean. For the A1B ensemble, local RSL change values range from -3.91 to 0.79 m, with a global mean of 0.47 m. Although the RSL amplitude differs, the spatial patterns are similar for all three emission scenarios. The spread in the projections is dominated by the distribution of the steric contribution, at least for the processes included in this study. Extreme ice loss scenarios may alter this picture. For individual sites, we find a standard deviation for the combined contributions of approximately 10 cm, regardless of emission scenario. (orig.)

  10. Zoos in the twenty-first century: Can't we find a better way to love nature?

    Dewey-Platt, Lauren Kay

    As a new millennium approaches, many forms of life on the planet and the environments in which they have evolved are increasingly threatened by human activities Wildlife is being marginalized, and native habitats are disappearing at an unprecedented rate. Equally disturbing is the impending demise of traditional human societies---peoples who have evolved outside of the confines and conditions of modern Western influence. The loss of these human and animal societies has occurred so rapidly that implications are largely unknown. Research on how modern Americans relate to animals, particularly wildlife, revealed a clear and disturbing incongruity best exemplified in the current paradigm of zoo exhibition and education. Although zoos purport to educate visitors about the ecology of natural environments and the universal plight of wildlife, research shows that people, particularly children, learn less about ecological principles in zoos with live animals than they do in non-living natural history exhibits. While designers employ a variety of visual techniques in natural history exhibition, environmental sound as an educational exhibit component is largely nonexistent. Many animal species communicate through sound, especially species in underwater environments. As the audio equivalent of a landscape, the soundscape is as important as any other habitat feature to the well-being of wildlife populations. Using recorded sounds of natural environments, an exhibition soundscape was designed and produced for Oceanario de Lisboa in Lisbon, Portugal---the centerpiece of the 1998 World Exposition in Lisbon, Portugal. With programmed sound serving as a major component of natural history exhibition, a conceptual design of a novel zoo for the twenty-first century was described. The "NewZew" concept is based on a growing awareness that the best way to save species is to salvage, preserve, and restore their natural habitats---activities that are largely antithetical to current zoo

  18. Proliferation and Nonproliferation in the Early Twenty-First Century. The Permanent Five Hold the Key to Success

    are. Its core finding is that much of the success against proliferation will be determined by the role played by the permanent members of the Security Council, the so-called Permanent Five or P-5 (China, France, Russia, the United Kingdom, and the United States). It is unclear, however, whether the Five will be able and willing to play this role adequately. The developments of the first decade of the twenty-first century have not been comforting for nonproliferation. Proliferation challenges have risen and grown more complex. In response, policy tools have been developed, but their effectiveness has suffered from divisions among the P-5 and between them and the NAM states. Half a century since Ikle's article and a decade since Roberts' review, the major powers have remained at a loss to address the threat of proliferation. Winning is still possible, but it will require more than wishful thinking. In the years ahead, the challenge will be to reconcile policy effectiveness with policy legitimacy, be it to restore compliance altogether or to prevent proliferation, counter it, detect and expose noncompliance, and manage nonproliferation failures. Meeting this challenge places the P-5 at the center-stage. Much of the success against proliferation will be determined by the role that the Five choose to play. But given current shifts in international power structures (what Joseph Nye calls 'the rise of the rest') the prospects appear uncertain.68 It is important, therefore, that further research focuses on how the P-5 role can be strengthened to address proliferation, and how this role can be better aligned with today's evolving international trends

  20. Beyond conventional energy use: A regionally based end-use approach for the twenty-first century

    Feder, Deborah R.

    In the United States, the dominant energy discourse is supply-oriented and focused on the large-scale use of fossil fuel and nuclear electricity energy resources. Fossil fuels and nuclear electricity are valued for the convenience, quality of life, and services that they provide. Despite these qualities, the laws of thermodynamics tell us that fossil fuels and nuclear electricity are not required for all end-use needs. Concentrated high quality energy sources such as fossil fuels and electricity are degraded when used for tasks such as water and space heating. The degraded energy is released into the environment as waste heat and pollution and contribute to scarcity in many realms. This dissertation suggests an alternative discourse on energy that calls on three frameworks of thinking: the nexus of relations, end-use analysis, and regional geography. The nexus of relations is a device for showing how different relations in society construct uses of energy that lead most naturally to scarcity and environmental degradation. End-use analysis is a framework for matching energy sources and end-uses based on thermodynamic quality, and regional geography is useful for identifying localized renewable energy sources and end-use needs. By combining these three approaches, a new framework has been created that matches thermodynamically appropriate renewable resources to end-use needs. This approach offers a new perspective on resource use that emphasizes how energy demands can be met, while minimizing scarcity and environmental degradation. To illustrate this regionally based end-use framework, a case study was conducted at three sites within Centre County, Pennsylvania. At each study site, the flux density of solar, wind, and water resources was evaluated and matched with local end-use needs. This exercise resulted in several findings: one, fossil fuel/nuclear electricity savings are possible at each study site; two, geographically-specific renewable resources can be used to

  1. Changing ideas in forestry: A comparison of concepts in Swedish and American forestry journals during the early twentieth and twenty-first centuries.

    Mårald, Erland; Langston, Nancy; Sténs, Anna; Moen, Jon

    2016-02-01

    By combining digital humanities text-mining tools and a qualitative approach, we examine changing concepts in forestry journals in Sweden and the United States (US) in the early twentieth and early twenty-first centuries. Our first hypothesis is that foresters at the beginning of the twentieth century were more concerned with production and less concerned with ecology than foresters at the beginning of the twenty-first century. Our second hypothesis is that US foresters in the early twentieth century were less concerned with local site conditions than Swedish foresters. We find that early foresters in both countries had broader-and often ecologically focused-concerns than hypothesized. Ecological concerns in the forestry literature have increased, but in the Nordic countries, production concerns have increased as well. In both regions and both time periods, timber management is closely connected to concerns about governance and state power, but the forms that governance takes have changed. PMID:26744044

  3. Twenty-first century wave climate projections for Ireland and surface winds in the North Atlantic Ocean

    Gallagher, Sarah; Gleeson, Emily; Tiron, Roxana; McGrath, Ray; Dias, Frédéric

    2016-04-01

    Ireland has a highly energetic wave and wind climate, and is therefore uniquely placed in terms of its ocean renewable energy resource. The socio-economic importance of the marine resource to Ireland makes it critical to quantify how the wave and wind climate may change in the future due to global climate change. Projected changes in winds, ocean waves and the frequency and severity of extreme weather events should be carefully assessed for long-term marine and coastal planning. We derived an ensemble of future wave climate projections for Ireland using the EC-Earth global climate model and the WAVEWATCH III® wave model, by comparing the future 30-year period 2070-2099 to the period 1980-2009 for the RCP4.5 and the RCP8.5 forcing scenarios. This dataset is currently the highest resolution wave projection dataset available for Ireland. The EC-Earth ensemble predicts decreases in mean (up to 2 % for RCP4.5 and up to 3.5 % for RCP8.5) 10 m wind speeds over the North Atlantic Ocean (5-75° N, 0-80° W) by the end of the century, which will consequently affect swell generation for the Irish wave climate. The WAVEWATCH III® model predicts an overall decrease in annual and seasonal mean significant wave heights around Ireland, with the largest decreases in summer (up to 15 %) and winter (up to 10 %) for RCP8.5. Projected decreases in mean significant wave heights for spring and autumn were found to be small for both forcing scenarios (less than 5 %), with no significant decrease found for RCP4.5 off the west coast in those seasons.

    2015-12-01

    Social cognitive theory guided the design of a survey to investigate high school students' perceptions of factors affecting their career contemplations and beliefs regarding the influence of their participation in the international Science Olympiad on their subject interests and twenty-first century skills. In addition, gender differences in students' choice of competition category were studied. Mixed methods analysis of survey returns from 172 Olympiad participants from 31 countries showed that students' career aspirations were affected most by their teachers, personal interests, and parents, respectively. Students also indicated that they believed that their participation in the Olympiad reinforced their plan to choose a science, technology, engineering, and mathematics (STEM) major at college and assisted them in developing and improving their twenty-first century skills. Furthermore, female students' responses indicated that their project choices were less likely to be in the engineering category and more likely to be in the environment or energy categories. Findings are discussed in the light of increasing the awareness of the role and importance of Science Olympiads in STEM career choice and finding ways to attract more female students into engineering careers.

    This study analyzes the impact of anthropogenic climate change in the hydroclimatology of Senegal with a focus over the lake of Guiers basin for the middle (2041-2060) and late twenty-first century (2080-2099). To this end, high-resolution multimodel ensemble based on regional climate model experiments considering two Representative Concentration Pathways (RCP4.5 and RCP8.5) is used. The results indicate that an elevated warming, leading to substantial increase of atmospheric water demand, is projected over the whole of Senegal. In the Lake basin, these increases in potential evapotranspiration (PE) range between 10 and 25 % in the near future and for RCP4.5 while for the far future and RCP8.5, they exceed 50 %. In addition, mean precipitation unveils contrasting changes with wetter (10 to 25 % more) conditions by the middle of the century and drier conditions (more than 50 %) during the late twenty-first century. Such changes cause more/less evapotranspiration and soil moisture respectively during the two future periods. Furthermore, surface runoff shows a tendency to increase in most areas amid few locations including the Lake basin with substantial reduction. Finally, it is found that while semi-arid climates develop in the RCP4.5 scenario, generalized arid conditions prevail over the whole Senegal for RCP8.5. It is thus evident that these future climate conditions substantially threaten freshwater availability for the country and irrigated cropping over the Lake basin. Therefore, strong governmental politics are needed to help design response options to cope with the challenges posed by the projected climate change for the country.

Embora a globalização seja um processo dinâmico em andamento, o seu avanço tem ocorrido de forma desequilibrada, gerando instabilidade política, econômica e social em várias regiões do planeta. O presente trabalho procura, de forma teórica, mostrar a falta da globalização social como um dos fatores que tem provocado desequilíbrio na dinâmica do processo de globalização. Pelo lado econômico, observa-se que a globalização ocorre de forma acelerada e já alcança os mais distantes pontos da face da Terra, ao passo que, pelo lado social, observa-se que a globalização está ausente em algumas regiões e, em outro tanto, ela ocorre de forma lenta e sem muito interesse. De nada vale os benefícios da globalização econômica se não existir a globalização social. Esse e o desafio do século XXI.The criticism of many of globalization is a consequence of directions it is taking.

    Regional climate change projections for the last half of the twenty-first century have been produced for South America, as part of the CREAS (Cenarios REgionalizados de Clima Futuro da America do Sul) regional project. Three regional climate models RCMs (Eta CCS, RegCM3 and HadRM3P) were nested within the HadAM3P global model. The simulations cover a 30-year period representing present climate (1961-1990) and projections for the IPCC A2 high emission scenario for 2071-2100. The focus was on the changes in the mean circulation and surface variables, in particular, surface air temperature and precipitation. There is a consistent pattern of changes in circulation, rainfall and temperatures as depicted by the three models. The HadRM3P shows intensification and a more southward position of the subtropical Pacific high, while a pattern of intensification/weakening during summer/winter is projected by the Eta CCS/RegCM3. There is a tendency for a weakening of the subtropical westerly jet from the Eta CCS and HadRM3P, consistent with other studies. There are indications that regions such of Northeast Brazil and central-eastern and southern Amazonia may experience rainfall deficiency in the future, while the Northwest coast of Peru-Ecuador and northern Argentina may experience rainfall excesses in a warmer future, and these changes may vary with the seasons. The three models show warming in the A2 scenario stronger in the tropical region, especially in the 5 N-15 S band, both in summer and especially in winter, reaching up to 6-8 C warmer than in the present. In southern South America, the warming in summer varies between 2 and 4 C and in winter between 3 and 5 C in the same region from the 3 models. These changes are consistent with changes in low level circulation from the models, and they are comparable with changes in rainfall and temperature extremes reported elsewhere. In summary, some aspects of projected future climate change are quite robust across this set of

  14. Lights, camera, action research: The effects of didactic digital movie making on students' twenty-first century learning skills and science content in the middle school classroom

    Ochsner, Karl

    Students are moving away from content consumption to content production. Short movies are uploaded onto video social networking sites and shared around the world. Unfortunately they usually contain little to no educational value, lack a narrative and are rarely created in the science classroom. According to new Arizona Technology standards and ISTE NET*S, along with the framework from the Partnership for 21st Century Learning Standards, our society demands students not only to learn curriculum, but to think critically, problem solve effectively, and become adept at communicating and collaborating. Didactic digital movie making in the science classroom may be one way that these twenty-first century learning skills may be implemented. An action research study using a mixed-methods approach to collect data was used to investigate if didactic moviemaking can help eighth grade students learn physical science content while incorporating 21st century learning skills of collaboration, communication, problem solving and critical thinking skills through their group production. Over a five week period, students researched lessons, wrote scripts, acted, video recorded and edited a didactic movie that contained a narrative plot to teach a science strand from the Arizona State Standards in physical science. A pretest/posttest science content test and KWL chart was given before and after the innovation to measure content learned by the students. Students then took a 21st Century Learning Skills Student Survey to measure how much they perceived that communication, collaboration, problem solving and critical thinking were taking place during the production. An open ended survey and a focus group of four students were used for qualitative analysis. Three science teachers used a project evaluation rubric to measure science content and production values from the movies. Triangulating the science content test, KWL chart, open ended questions and the project evaluation rubric, it

    2014-05-01

    Water scarcity affects large parts of the world. Over the course of the twenty-first century, water demand is likely to increase due to population growth and associated food production, and increased economic activity, while water supply is projected to decrease in many regions due to climate change. Despite recent studies that analyze the effect of climate change on water scarcity, e.g. using climate projections under representative concentration pathways (RCP) of the fifth assessment report of the IPCC (AR5), decision support for closing the water gap between now and 2100 does not exist at a meaningful scale and with a global coverage. In this study, we aimed (i) to assess the joint impact of climatic and socio-economic change on water scarcity, (ii) to integrate impact and potential adaptation in one workflow, (iii) to prioritize adaptation options to counteract water scarcity based on their financial, regional socio-economic and environmental implications, and (iv) to deliver all this information in an integrated user-friendly web-based service. To enable the combination of global coverage with local relevance, we aggregated all results for 1604 water provinces (food producing units) delineated in this study, which is five times smaller than previous food producing units. Water supply was computed using the PCR-GLOBWB hydrological and water resources model, parameterized at 5 arcminutes for the whole globe, excluding Antarctica and Greenland. We ran PCR-GLOBWB with a daily forcing derived from five different GCM models from the CMIP5 (GFDL-ESM2M, Hadgem2-ES, IPSL-CMA5-LR, MIROC-ESM-CHEM, NorESM1-M) that were bias corrected using observation-based WATCH data between 1960-1999. For each of the models all four RCPs (RCP 2.6, 4.5, 6.0, and 8.5) were run, producing the ensemble of 20 future projections. The blue water supply was aggregated per month and per water province. Industrial, domestic and irrigation water demands were computed for a limited number of

  6. Recent incentives for renewable energy in Turkey

    Recently, the importance of renewable energy sources has increased significantly as climate change has become an important long term threat to global ecosystems and the world economy. In the face of increased concern about climate change and high fossil fuel costs together with a reduction in the primary energy sources such as oil, natural gas and coal, alternative energy sources (renewables) are increasingly needed to respond to the threat of climate change and growing energy demand in the world. Recent developments in Turkey, such as the liberalization of the electricity market and improvements in the renewable legislations, have accelerated the growth process and investment opportunities in the field of renewable energy. Turkey′s naturally endowed potential for renewables, such as solar, geothermal and wind, also accompanied these developments and attracted world attention to this market. In Turkey, renewable energy sources have gained great importance in the last decades due to growing energy demand and incentive policies which foster the utilization of renewable energy sources. This study aims to explore the availability and potential of renewable energy sources in Turkey and discuss the government policies and economic aspects. - highlights: • Turkey′s potential for renewable energy has attracted world attention. • Turkey has specific energy objectives in promoting renewable energy. • This paper evaluates recent incentives for renewable energy in Turkey. • Incentives in Turkey have led to more investment in renewable energy generation

  7. Mitigation of global warming through renewable biomass

    Rising level of atmospheric CO2 and consequent global warming is evident. Global surface temperature have already increased by 0.8 °C over the 20th century and is projected to increase by 1.4–5.8 °C during the twenty-first century. The global warming will continue till atmospheric concentrations of the major greenhouse gases are stabilized. Among them, CO2 is mainly responsible and is expected to account for about 60% of the warming over the next century. This study reviews advances on causes and consequences of global climate change and its impact on nature and society. Renewable biomass has tremendous potential to mitigate the global warming. Renewable biomass is expected to play a multifunctional role including food production, source of energy and fodder, biodiversity conservation, yield of goods and services to the society as well as mitigation of the impact of climate change. The review highlights the different management and research strategies in forestry, agriculture, agroforestry and grasslands to mitigate the global warming. -- Highlights: ► Rising level of atmospheric CO2 and consequent global warming is evident. ► CO2 is mainly responsible for global warming. ► Global temperature is predicted to increase by 1.4–5.8 °C during 21st century. ► Renewable biomass has great potential to mitigate the global warming

    international solar and renewable energy professional societies, in identifying the range and level of teaching materials required for use at schools and universities. 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.

  11. Renewing governance.

    Loos, Gregory P

    2003-01-01

    Globalization's profound influence on social and political institutions need not be negative. Critics of globalization have often referred to the "Impossible Trinity" because decision-making must 1. respect national sovereignty, 2. develop and implement firm regulation, and 3. allow capital markets to be as free as possible. To many, such goals are mutually exclusive because history conditions us to view policy-making and governance in traditional molds. Thus, transnational governance merely appears impossible because current forms of governance were not designed to provide it. The world needs new tools for governing, and its citizens must seize the opportunity to help develop them. The rise of a global society requires a greater level of generality and inclusion than is found in most policy bodies today. Politicians need to re-examine key assumptions about government. States must develop ways to discharge their regulatory responsibilities across borders and collaborate with neighboring jurisdictions, multilateral bodies, and business. Concepts such as multilateralism and tripartism show great promise. Governments must engage civil society in the spirit of shared responsibility and democratic decision-making. Such changes will result in a renewal of the state's purpose and better use of international resources and expertise in governance. PMID:17208717

    Full Text Available Undoubtedly, the twenty-first century has witnessed rapid changes and developments in the information world. As science and technology develop, sharing information and knowledge has been accelerated. Digital tools are of paramount importance and play an important role in the production and sharing of this information. The world has become a global village by means of digital tools. Digital skills are also an important sub-dimension of lifelong learning. Within this context, our teachers to educate the people of our age are required to acquire and use these skills throughout their lives in order to catch our era in which the information production and sharing are accelerated. The aim of this study is to assess digital competence of teachers within the context of lifelong learning and in the light of the twenty-first century skills. Scope of this study includes teachers in service at high school and junior high school in Diyarbakır, during the spring semester of 2014-2015 academic years. The sample of the study consisted of 286 teachers randomly selected from the population. One of the descriptive research models, survey model has been used in this study. As data collection tool, a scale developed by researchers was used. Developed scale consists of 30 items and three-dimensional. SPSS software was used for analysing the data. In data analysis, digital qualifications of teachers was both examined overall and compared in terms of gender, level of education, branch, school type, institutions, seniority and whether to take computer lessons or courses variables. According to the results obtained, it was observed that teachers have digital qualifications at ‘Adequate level ( =3,5’, male teachers are more qualified than female teachers and having studied computing either in university or another institution significantly increases digital qualifications.  The results obtained were compared with similar studies in literature and the following

  16. Tailings management for the twenty-first century

    The evolution of tailings management at Saskatchewan uranium mines is traced from the fifties to the nineties. Some of the problems with past systems are discussed. The new tailings systems now being proposed for the new operations currently undergoing environmental assessment in Saskatchewan are examined in detail. These new systems represent a change in tailings management philosophy, from keeping tailings high and dry on the surface, to placement of tailings in a low-energy regime within the water table. There they are removed from the active surface environment, avoiding future erosion problems, with a reduced likelihood of suffering intrusion from future human or animal activities.

  18. Water and Food in the Twenty-First Century

    de Marsily, Ghislain; Abarca-del-Rio, Rodrigo

    2016-03-01

    In 2000, the World population was 6.2 billion people; it reached 7 billion in 2012 and is expected to reach 9.5 billion (±0.4) in 2050 and 11 billion (±1.5) in 2100, according to the 2012 UN projections (Gerland et al. in Science 346:234-237, 2014). The trend after 2100 is still one of the global demographic growths, but after 2060, Africa is the only continent where the population would still increase. The amount of water consumed annually to produce the food necessary to meet the needs of the populations varies greatly between countries, from about 600 to 2500 m3/year per capita (Zimmer in L'empreinte eau. Les faces cachées d'une ressource vitale. Charles Léopold Meyer, Paris, 2013), depending on their wealth, their food habits, and the percentage of food waste they generate (on average, 30 % of the food produced is wasted). In 2000, the total food production was on the order of 3300 million tons (in cereal equivalents). In 2014, it is estimated that about 0.8 billion inhabitants of the planet suffer from hunger (FAO in World agriculture: towards 2030-2050. FAO, Rome, 2014. http://www.fao.org/docrep/004/Y3557E/y3557e00.HTM) and do not get the nutrition they need to be in good health or, in the case of children, to grow properly (both physically and intellectually). This food deficit was on the order of 40 million tons of cereal equivalents in 2014. The number of inhabitants with a food deficit was about 0.85 billion before the 2008 crisis and was decreasing annually, but it increased abruptly after 2008 up to 1 billion inhabitants and is slowly decreasing now. Assuming a World average water consumption for food of 1300 m3/year per capita in 2000, 1400 m3/year in 2050, and 1500 m3/year in 2100, a volume of water of around 8200 km3/year was needed in 2000, 13,000 km3/year will be needed in 2050, and 16,500 km3/year in 2100 (Marsily in L'eau, un trésor en partage. Dunod, Paris, 2009). Can bioenergy be added to food production? Will that much water be available on Earth, and where will it come from? Is climate change going to modify the answers to these questions? Can severe droughts occur? Can there be conflicts related to a food deficit? Some preliminary answers and scenarios for food production will be given in this paper from a hydrologist's viewpoint.

    Recognizing that tuberculosis (TB) is still the leading cause of human death from a curable infection, the international health community has set ambitious targets for disease control. One target is to eliminate TB by 2050; that is, to cut the annual incidence of new cases to less than 1 per million population. National TB control programmes are working to eliminate TB mainly by intensifying efforts to find and cure patients with active disease. Here, we use mathematical modelling to show tha...

  20. Eating disorders in the twenty-first century.

    Weiselberg, E C; Gonzalez, M; Fisher, M

    2011-12-01

    The first description of anorexia nervosa appeared in the literature over three hundred years ago. Since then, much has been learned about eating disorders, including the different presentations, medical complications, prognosis, and treatment strategies. In spite of this knowledge, the prevalence of eating disorders continues to grow. As well, eating disorders are seen in increasing frequency among males, children, and adults, and from all cultures and ethnicities. Of particular concern, is that patients with eating disorders often first present because of a complication such as amenorrhea, syncope, or abdominal pain, without disclosing the eating disorder. Therefore, all physicians should be aware of the various presentations of eating disorders, including the medical complications and risks, and be able to screen for a possible eating disorder. The major medical complications are due to the decreased caloric intake which leads to a hypometabolic state. While most complications are reversible with recovery, some, such as bone loss, may not be. Of particular concern during recovery is the possible development of a refeeding syndrome which occurs as the body goes from a catabolic to an anabolic state, causing hypophosphatemia, hypocalcemia and hypomagnesemia, which can lead to delirium, coma and death. Of further concern is that eating disorders have the highest mortality rate of all psychiatric disorders at 5.6% per decade. This article will review the changing demographics, medical complications, treatment options, and prognosis of eating disorders. PMID:22036757

    Lucian A. Lucia

    2012-01-01

    Full Text Available The importance of teaching, for the development of economies, cultures, and the enrichment of people’s lives cannot be overstated. These days biomass and bioenergy teaching has a pivotal role to play in influencing all of the aforementioned areas of life, since fossil fuels are becoming depleted. However, what good is teaching if it cannot be communicated in an intelligible, persuading, and egalitarian manner? A dynamic educational construct between “teacher” and “student” will be the chief mode of promoting knowledge and provoking research for engendering more knowledge. This editorial attempts to show how teaching is a living and symbiotic discipline that we typically take for granted, but once we do it right, we have the power to change the world as we know it. We will briefly explore the example of BioSUCCEED, a platform at NC State University, as a means of communicating knowledge related to biomass and bioenergy.

    Collins, Harry

    2011-01-01

    In theory, at least, gravitational waves do exist. We are constantly bathed in gravitational radiation, which is generated when stars explode or collide and a portion of their mass becomes energy that ripples out like a disturbance on the surface of a serene pond. But unfortunately no gravitational wave has ever been directly detected even though the search has lasted more than forty years. As the leading chronicler of the search for gravitational waves, Harry Collins has been right there with the scientists since the start.

    Young, Anthony

    2015-01-01

    Young addresses the impressive expansion across existing and developing commercial space business markets, with multiple private companies competing in the payload launch services sector. The author pinpoints the new markets, technologies, and players in the industry, as well as highlighting the overall reasons why it is important for us to develop space. NASA now relies on commercial partners to supply cargo and crew spacecraft and services to and from the International Space Station. The sizes of satellites are diminishing and their capabilities expanding, while costs to orbit are decreasing. Suborbital space tourism holds the potential of new industries and jobs. Commercial space exploration of the Moon and the planets also holds promise. All this activity is a catalyst for anyone interested in joining the developing space industry, from students and researchers to engineers and entrepreneurs. As more and more satellites and rockets are launched and the business of space is expanding at a signifi...

  8. Capital in the twenty-first century: a critique.

    Soskice, David

    2014-12-01

    I set out and explain Piketty's model of the dynamics of capitalism based on two equations and the r > g inequality (his central contradiction of capitalism). I then take issue with Piketty's analysis of the rebuilding of inequality from the 1970s to the present on three grounds: First, his model is based on the (neo-classical) assumption that companies are essentially passive actors who invest the amount savers choose to accumulate at equilibrium output - leading to the counterintuitive result that companies respond to the secular fall in growth (and hence their product markets) from the 1970s on by increasing their investment relative to output; this does indeed imply increased inequality on Piketty's β measure, the ratio of capital to output. I suggest a more realistic model in which businesses determine investment growth based on their expectations of output growth, with monetary policy bringing savings into line with business-determined investment; the implication of this model is that β does not change at all. And in fact as other recent empirical work which I reference has noted, β has not changed significantly over these recent decades. Hence Piketty's central analysis of the growth of contemporary inequality requires rethinking. Second, despite many references to the need for political economic analysis, Piketty's analysis of the growth of inequality in the period from the 1970s to the present is almost devoid of it, his explanatory framework being purely mathematical. I sketch what a political economic framework might look like during a period when politics was central to inequality. Third, inequality in fact rose on a variety of dimensions apart from β (including poverty which Piketty virtually makes no reference to in this period), but it is unclear what might explain why inequality rose in these other dimensions.

  9. Organic agriculture in the twenty-first century.

    Reganold, John P; Wachter, Jonathan M

    2016-01-01

    Organic agriculture has a history of being contentious and is considered by some as an inefficient approach to food production. Yet organic foods and beverages are a rapidly growing market segment in the global food industry. Here, we examine the performance of organic farming in light of four key sustainability metrics: productivity, environmental impact, economic viability and social wellbeing. Organic farming systems produce lower yields compared with conventional agriculture. However, they are more profitable and environmentally friendly, and deliver equally or more nutritious foods that contain less (or no) pesticide residues, compared with conventional farming. Moreover, initial evidence indicates that organic agricultural systems deliver greater ecosystem services and social benefits. Although organic agriculture has an untapped role to play when it comes to the establishment of sustainable farming systems, no single approach will safely feed the planet. Rather, a blend of organic and other innovative farming systems is needed. Significant barriers exist to adopting these systems, however, and a diversity of policy instruments will be required to facilitate their development and implementation. PMID:27249193

  15. Censusing marine eukaryotic diversity in the twenty-first century.

    Leray, Matthieu; Knowlton, Nancy

    2016-09-01

    The ocean constitutes one of the vastest and richest biomes on our planet. Most recent estimations, all based on indirect approaches, suggest that there are millions of marine eukaryotic species. Moreover, a large majority of these are small (less than 1 mm), cryptic and still unknown to science. However, this knowledge gap, caused by the lack of diagnostic morphological features in small organisms and the limited sampling of the global ocean, is currently being filled, thanks to new DNA-based approaches. The molecular technique of PCR amplification of homologous gene regions combined with high-throughput sequencing, routinely used to census unculturable prokaryotes, is now also being used to characterize whole communities of marine eukaryotes. Here, we review how this methodological advancement has helped to better quantify the magnitude and patterns of marine eukaryotic diversity, with an emphasis on taxonomic groups previously largely overlooked. We then discuss obstacles remaining to achieve a global understanding of marine eukaryotic diversity. In particular, we argue that 18S variable regions do not provide sufficient taxonomic resolution to census marine life, and suggest combining broad eukaryotic surveys targeting the 18S rRNA region with more taxon-focused analyses of hypervariable regions to improve our understanding of the diversity of species, the functional units of marine ecosystems.This article is part of the themed issue 'From DNA barcodes to biomes'.

    Full Text Available Current educational interventions and training courses in microsurgery are often predicated on theories of skill acquisition and development that follow a ‘practice makes perfect’ model. Given the changing landscape of surgical training and advances in educational theories related to skill development, research is needed to assess current training tools in microsurgery education and devise alternative methods that would enhance training . Simulation is an increasingly important tool for educators because, whilst facilitating improved technical proficiency, it provides a way to reduce risks to both trainees and patients. The International Microsurgery Simulation Society has been founded in 2012 in order to consolidate the global effort in promoting excellence in microsurgical training.

  4. Rheumatic Heart Disease in the Twenty-First Century.

    Woldu, Bethel; Bloomfield, Gerald S

    2016-10-01

    Rheumatic heart disease (RHD) is a chronic valvular disease resulting after severe or repetitive episodes of acute rheumatic fever (ARF), an autoimmune response to group A Streptococcus infection. RHD has been almost eliminated with improved social and health infrastructure in affluent countries while it remains a neglected disease with major cause of morbidity and mortality in many low- and middle-income countries, and resource-limited regions of high-income countries. Despite our evolving understanding of the pathogenesis of RHD, there have not been any significant advances to prevent or halt progression of disease in recent history. Long-term penicillin-based treatment and surgery remain the backbone of a RHD control program in the absence of an effective vaccine. The advent of echocardiographic screening algorithms has improved the accuracy of diagnosing RHD and has shed light on the enormous burden of disease. Encouragingly, this has led to a rekindled commitment from researchers in the most affected countries to advocate and take bold actions to end this disease of social inequality. PMID:27566329

  7. Particle physics of the twenty-first century

    Elementary particle physics is the science devoted to searching for the ultimate constituents of matter and the interactions among them. The last 20 years has seen the emergence of the Standard Model. This is the single unified picture which gives us a language for discussing all the phenomena we see about us and for organizing that information and trying to understand it. Another important development has been the formulation of a mathematical expression for the forces of nature. These are called the gauge theories of the strong, weak, and electromagnetic interactions. The Standard Model has a couple of basic facets. One is that the elementary particles are quarks and leptons. Leptons experience gravitational, weak, and electromagnetic interactions and quarks experience the strong interaction. The carriers of these interactions are gluon for the strong, photon for the electromagnetic, intermediate bosons for the weak, and graviton for gravity. These facts have emerged through experiments using accelerators and detectors. However at energies for collisions among the fundamental constituents of about 1 TeV, the Standard Model ceases to make sense, so it can not be complete. Something else must be happening. Hence, more experiments need to be carried out. The instrument chosen for this is the Superconducting Super Collider. 12 figures, 1 table

  9. Continuing Professional Development in the Twenty-First Century.

    Sachdeva, Ajit K

    2016-01-01

    The critical role of continuing professional development (CPD) in supporting delivery of patient care of the highest quality and safety is receiving significant attention in the current era of monumental change. CPD is essential in efforts to ensure effectiveness of new models of health care delivery, improve outcomes and value in health care, address external regulations, and foster patient engagement. The unique features of CPD; the use of special mastery-based teaching, learning, and assessment methods, and other special interventions to promote excellence; and direct involvement of a variety of key stakeholders differentiate CPD from undergraduate medical education and graduate medical education. The needs of procedural specialties relating to CPD are different from those of primary care disciplines and require special attention for the greatest impact. Simulation-based education and training can be very useful in CPD aimed at improving outcomes and promoting patient safety. Preceptoring, proctoring, mentoring, and coaching should be used routinely to address specific needs in CPD. Distinct CPD strategies are necessary for retraining, reentry, and remediation. Participation in CPD programs can be encouraged by leveraging the joy of learning, which should drive physicians and surgeons to strive continually to be the best in their professional work.

  10. Twenty-first century brain banking: at the crossroads.

    Graeber, Manuel B

    2008-05-01

    Brain banks form an increasingly important resource for research. In view of declining autopsy rates, brain banks are also gaining importance for medical diagnostics, quality control and teaching. In the case of neurodegenerative diseases, brain banks have become drivers of discovery and are yielding invaluable taxonomic references for neuropathologists. This article provides comments on two recent landmark papers in the field (Bell JE et al. Acta Neuropathol 2008. doi:10.1007/s00401-008-0358-8; Vonsattel JP et al. Acta Neuropathol 2008. doi:10.1007/s00401-007-0311-9). Professionalisation of brain banking standards, ethical principles safeguarding the running of a brain bank and a proposed code of conduct for brain bank staff are outlined and discussed. Special emphasis is placed on the need to enable sustainability of the human brain tissue resource in the face of increased financial pressures on medical institutions and raised public expectations towards ethical human brain banking in a globalised economic environment. It is proposed that brain banks undergo rigorous international audit as a prerequisite for their registration with the relevant national neuropathological society. This promises to be an important safeguard so that proper standards can be assured when tissue is handed out to commercial companies. Honesty, accountability and complete transparency are mandatory to allow long-lasting success of the brain banking operation by guaranteeing that the best possible use is made of the tissue. Preferred access by private tissue users must be avoided and money must never be allowed to buy access to a brain bank. Since brain banks operate internationally, any mistake made may be felt around the globe and could endanger the public's willingness to donate brains for research. The much-needed increase in the number of control brain donations will only be achievable if broad-based support from the general public can be won and maintained. PMID:18347804

  11. Marketing of science in the twenty-first century

    The author gives a brief review of marketing of science from the 1930's to the present. He discusses the fact that at the present the scientific community is doing a lousy job of marketing and the fact that it is very important that this be reversed because science and technology have become absolutely essential to our future economic health and development. The four steps which he proposes will help with this problem are: (1) government, universities and industry working together to try and insure that there's an adequate basis of curiosity-driven research; (2) scientist making an effort to insure that they have enough political power to be taken seriously; (3) an adjustment to scientist thinking to reflect the fiscal realities of what the next generation of scientific facilities will cost; and (4) a need for public support

  15. Two-generation programs in the twenty-first century.

    Chase-Lansdale, Lindsay; Brooks-Gunn, Jeanne

    2014-01-01

    Most of the authors in this issue of Future of Children focus on a single strategy for helping both adults and children that could become a component of two-generation programs. Lindsay Chase-Lansdale and Jeanne Brooks-Gunn, on the other hand, look at actual programs with an explicit two-generation focus that have been tried in the past or are currently under way. These explicitly two-generation programs have sought to build human capital across generations by combining education or job training for adults with early childhood education for their children. Chase-Lansdale and Brooks-Gunn explain the theories behind these programs and review the evidence for their efficacy. A first wave of such programs in the 1980s and 1990s produced mostly disappointing results, but the evaluations they left behind pointed to promising new directions. More recently, a second wave of two-generation programs--the authors dub them "Two-Generation 2.0"--has sought to rectify the flaws of earlier efforts, largely by building strong connections between components for children and adults, by ensuring that children and adults receive services of equal duration and intensity, and by incorporating advances in both education and workforce development. These Two-Generation 2.0 programs are still in their infancy, and we have yet to see clear evidence that they can achieve their goals or be implemented cost-effectively at scale. Nonetheless, Chase-Lansdale and Brooks-Gunn write, the theoretical justification for these programs is strong, their early results are promising, and the time is ripe for innovation, experimentation, and further study.

    Full Text Available Na virada do século, assistimos a um reforço do sistema de patentes. No entanto, os gestores de políticas deixam sistematicamente de lado as controvérsias sobre patentes. Este artigo examina criticamente as complexas relações entre, por um lado, as razões para os direitos de patente e, por outro lado, seus efeitos sociais e econômicos. Só quando entendermos essa relação, seremos capazes de projetar regimes adequados de Direitos de Propriedade Intelectual (DPI para o novo paradigma tecnoeconômico de microeletrônica baseada em conhecimento e invenções de amplo alcance implementadas por computador. O foco se concentra nas razões morais, nas razões de incentivo econômico, e nas razões de aumento da concorrência e "proteção do talento empresarial no mercado", e nas razões econômicas para organizar ciência, tecnologia e criatividade. Afirma-se aqui que os sistemas de patentes não são neutros, eles estabelecem as regras do jogo em que indivíduos e organizações são os jogadores.At the turn of the century we have seen a tightening of the patent system. However, policy makers systematically neglect the patent controversies. This article critically reviews the complex relationships between the rationales for patent rights on the one hand, and the social and economic effects of such on the other hand. Only when we understand this relationship, will we be able to design appropriate Intellectual Property Right (IPR regimes for the new technoeconomic paradigm of knowledge-based micro-electronics and computer implemented pervasive inventions. Focus is on moral rationales, economic incentive rationales, increased competition and "market protection of entrepreneurial talent" rationales, and the economic rationales for organizing science, technology and creativity. It is argued that patent systems are not neutral, but set the rules of the game in which individuals and organizations are the players.

  2. Strategic nutrition: a vision for the twenty-first century.

    Temple, Norman J

    2016-01-01

    It is now widely accepted that poor nutrition plays a major role in the epidemic of various diseases, including obesity, type 2 diabetes and CVD. There has also been much research regarding the role of related factors such as advertising and food prices. Many intervention studies have been carried out where attempts have been made to persuade people to modify their behaviour, such as by making dietary changes, in order to enhance health (health promotion). There has also been much debate on the potential of government policy as a tool for achieving these goals. Various proposals have been made, such as a tax on sugary drinks, the redirection of food subsidies and how the salt content of food can be reduced. However, the great majority of previous papers have considered only single aspects of the topics discussed here. The present paper reviews strategies for improving public health, both health promotion interventions and the use of government policy approaches. Topics discussed include providing advice for the general population and the design of food guides and food labels. This leads to the conclusion that we need an overall strategy that integrates this diverse body of information and formulates a comprehensive action plan. I propose the term 'strategic nutrition'. The implementation of this plan opens up a path to a major advance in public health. PMID:25638207

    2009-03-01

    Although most of sacral perineural cysts are asymptomatic, some may produce symptoms. Specific radicular pain may be due to distortion, compression, or stretching of nerve root by a space occupying cyst. We report a rare case of S1 radiculopathy caused by sacral perineural cyst accompanying disc herniation. The patient underwent a microscopic discectomy at L5-S1 level. However, the patient's symptoms did not improved. The hypesthesia persisted, as did the right leg pain. Cyst-subarachnoid shunt was set to decompress nerve root and to equalize the cerebrospinal fluid pressure between the cephalad thecal sac and cyst. Immediately after surgery, the patient had no leg pain. After 6 months, the patient still remained free of leg pain. PMID:19352483

Neuroimaging due to a visual field defect revealed a right parietooccipital lesion, which was initially misdiagnosed as a tumor. Pathological examination showed that it was demyelinating in nature. Peripheral nervous symptoms of the patient developed two years later and she was then diagnosed with MADSAM. There was prominent clinical and electrophysiological response to steroid treatment. Tumefactive brain involvement was not previously reported for MADSAM neuropathy, although it was documented in a single case with typical chronic inflammatory demyelinating polyneuropathy (CIDP. CNS involvement should therefore be considered in MADSAM patients.

  8. Bilateral foveal retinoschisis accompanying unilateral peripheral retinoschisis

    Full Text Available X-linked juvenile retinoschisis is a rare hereditary retinal disease characterized by a tangential splitting of the neurosensory retina which may cause early-onset visual impairment. Existence of the retinal neurosensory layer splitting on cross-sectional images of optical coherance tomography (OCT and the absence of leakage on fluorescein angiography (FA help confirming the diagnosis. Such diagnostic tests are also helpful in determining the management of the disease. However, most of the retinoschisis cavities remain stable and rarely extend to the posterior pole, many authors suggest laser prophylaxis to avoid the potential risk of retinal detachment due to holes in the outer retinal layer. Herein, we report a case with bilateral foveal retinoschisis accompanying unilateral peripheral retinoschisis who was evaluated with detailed ophthalmologic examination. Visual acuity, fundoscopy, OCT, and FA remained stable in the second year of follow-up after prophylactic argon laser treatment.

    2010-12-01

    The purpose of this study was to evaluate surgical complications accompanying the introduction of orthotopic liver transplantation (OLT) in Estonia. Between 1999 and 2009, we performed the first 12 liver transplantations. Eight patients were males and four were females of age range 12 to 67 years. Their diagnoses were cholestatic disease (n = 5); tumor (n = 3); hepatitis C virus cirrhosis (n = 2); Budd-Chiari syndrome (n = 1); and cystic fibrosis (n = 1). Technical complications occurred in 7/12 patients. The early vascular complications in two patients were a suprahepatic vena cava lesion occurring at liver extraction, which resulted in uncontrolled suprahepatic bleeding after liver perfusion; the recipient died during transplantation. The other case displayed a right intrahepatic portal venous thrombosis, which was treated successfully with thrombolysis and anticoagulant therapy. Early biliary complications of biliary leaks occurred in three patients: two had undergone duct-to-duct reconstructions, which were treated by endoscopic retrograde cholangiography that successfully managed the anastomotic and recipient cystic duct leaks with a papillotomy and stenting. In one patient with a duct-to-jejunum anastomosis, a bile leak stopped at 3 weeks but he needed surgical therapy 2 years later due to an anastomotic stricture. Severe decubitus occurred in the lumbosacral region of the subjects with operating times of 14 hours. They required necretectomy and plastic surgery. One of them with postoperative intra-abdominal hypertension also displayed wound eventration requiring reoperations. The rate of hepatic (5/12) and extrahepatic (3/12) surgical complications, as well as of 1-year survival (9/12), in our period of implementation of OLT were satisfactory to continue OLT development in Estonia.

  15. Auroral pulsations and accompanying VLF emissions

    V. R. Tagirov

    Full Text Available Results of simultaneous TV observations of pulsating auroral patches and ELF-VLF-emissions in the morning sector carried out in Sodankylä (Finland on February 15, 1991 are presented. Auroral pulsating activity was typical having pulsating patches with characteristic periods of about 7 s. Narrow-band hiss emissions and chorus elements at intervals of 0.3–0.4 s formed the main ELF-VLF activity in the frequency range 1.0–2.5 kHz at the same time. The analysis of auroral images with time resolution of 0.04 s allowed perfectly separate analysis of spatial and temporal variations in the auroral luminosity. Mutual correspondence between the behaviour of the luminous auroral patches and the appearance of ELF noise type hiss emissions and VLF chorus trains was found in two intervals chosen for analysis. While the hiss emissions were associated with the appearance of luminosity inside a limited area close to the zenith, the structured VLF emissions were accompanied by rapid motion of luminosity inside the area. The spatial dimension of the pulsating area was about 45–50 km and luminosity propagated inside it with velocity of about 10–12 kms. We discuss a new approach to explain the 5–15 s auroral pulsation based on the theory of flowing cyclotron maser and relaxation characteristics of ionosphere.

    2012-07-01

    This paper builds on IEA publications, Deploying Renewables, Principles for Effective Policies and Deploying Renewables, Best and Future Policy Practice, that discuss the 'integrated policy approach,' whereby renewable energy technologies require different support policies at different stages of their maturity pathways. The paper discusses how the integrated policy approach applies to renewable heat. It attempts to provide guidance for policy-makers on renewable heat throughout the different phases of the policy lifecycle, allowing for the specific challenges of renewable heat and needs of the many stakeholders involved. Stimulating a market for heat involves challenges that are different and, often, more difficult to overcome than in the electricity and transport sectors.

    The use of renewable materials is essential in future technologies to harmonize with our living environment. Renewable materials can maintain our resources from the environment so as to overcome degradation of natural environmental services and diminished productivity. This paper reviews recent advancement of renewable materials for smart material applications, including wood, cellulose, chitin, lignin, and their sensors, actuators and energy storage applications. To further improve functionality of renewable materials, hybrid composites of inorganic functional materials are introduced by incorporating carbon nanotubes, titanium dioxide and tin oxide conducting polymers and ionic liquids. Since renewable materials have many advantages of biocompatible, sustainable, biodegradable, high mechanical strength and versatile modification behaviors, more research efforts need to be focused on the development of renewable smart materials.

  19. Renewable energy export network

    A Renewable Energy Exporters Network (REEN) has recently been established, following a meeting of renewable energy exporters and government agencies on 30 October 2000. REEN will assist the Australian renewable energy industry to take advantage of the opportunities offered by the burgeoning global market for renewable energy goods and services. Recent estimates of the significant potential global growth is renewable energy demand have reinforced the industry and Government's view that, in the medium to long-term, growth in the Australian renewable energy industry will largely depend on capturing export market share. Expanding the export market was identified as a crucial component in the Renewable Energy Action Agenda, developed jointly by industry and Government and released in June 2000. It was estimated that, for the industry to achieve its vision of sales of $4 billion per year by 2010, exports would need to comprise approximately 50% of the forecast growth in sales. As such, the need for a specific export strategy for the Australian renewable energy industry was recognised in the Action Agenda, and the establishment of the REEN is one of the first initiatives undertaken as part of the Renewable Energy Export Strategy. The REEN comprises approximately 50 export-ready renewable energy companies, the Department of Industry, Science and Resources, Austrade, and Stage Government agencies such as NSW's Sustainable Energy Development Authority. The Export Network will operate electronically, with face-to-face meetings held as appropriate. The Department of Industry, Science and Resources will facilitate the Export Network and has published a website at www.isr.gov.au/industry/reen. The site includes: a members directory; a discussion forum; information on opportunities to showcase Australian renewable; energy products and services; and Iinks to sites containing information that may be useful to renewable energy exporters.

  2. Renewable energy resources

    Although the need to decarbonise our global economy and thus in particular the supply of energy to limit the global temperature increase is internationally undisputed the German politics in 2014 has significantly contributed less compared to previous years in order to attain this objective. The expansion of renewable energies in the electricity sector has decelerated significantly; and in the heating and mobility area no new impulses were set in relation to renewable energies. In addition, a dramatic fallen oil price makes it difficult to increase the use of renewable energy supply. Based on these deteriorated framework conditions compared to conditions of the previous years, the developments in Germany of 2014 are shown in the electricity, heat and transport sector in the field of renewable energy. For this purpose - in addition to a discussion of the current energy economic framework - for each option to use renewable energies the state and looming trends are analyzed.

  4. Programs in Renewable Energy

    1990-01-01

    Our nation faces significant challenges as we enter the 1990s: securing a reliable supply of competitively priced energy, improving the quality of our environment, and increasing our share of foreign markets for goods and services. The US Department of Energy's (DOE) Programs in Renewable Energy are working toward meeting these challenges by developing the technologies that make use of our nation's largest energy resource: renewable energy. The sunlight, wind biomass, flowing water, ocean energy, and geothermal energy that make up the renewable energy resource can be found throughout our nation. These resources can provide all the forms of energy our nation needs: liquid fuels, electricity, and heating and cooling. Renewable energy meets about 10% of our need for these forms of energy today, yet the potential contribution is many times greater. DOE's Programs in Renewable Energy are working side-by-side with American industry to develop the technologies that convert renewable energy resources into practical, cost-competitive energy. After a decade of progress in research, several of these technologies are poised to make large contributions during the 1990s and beyond. This booklet provides an overview of the renewable energy programs and their plans for FY 1990. Sources of additional information are listed at the back of the booklet. 48 figs., 4 tabs.

  6. Tax barriers to four renewable electric generation technologies

    The tax loads associated with constructing and owning current and advanced solar central receiver, biomass-electric, and flash and binary cycle geothermal projects are compared to the tax loads incurred by natural gas-fired generation matched in size, hours of operation, and technology status. All but one of the eight renewable projects carry higher tax burdens under current tax codes. These higher tax loads proportionately reduce the competitiveness of renewables. Three tax neutralizing policies are applied to the renewable projects, each restoring competitiveness for some of the projects. The results show that RD and D must be accompanied with such public initiatives as tax neutrality in order for the majority of renewable projects to compete with advanced gas turbines in the emerging electric services market

  7. REFITS - an instrument for renewables' market launch besides others

    Achieving a sustainable energy supply requires the global turn of energy policy: Phasing out nuclear technology, cutting off the 'oil-drip' and replacing them by renewable energies, economical use of energy and energy efficiency. To reach the German Federal Government's goal of meeting 20 % of the needs of electricity by renewable energies until 2020 the increasing use of biomass - providing a reasonable mix of all lines of renewable energies - is an important premise in the future. Biomass is predicted to have a promising future because of its exceeding potential. It is the most multifaceted type of energy use requiring a well adapted and flexible raft of measures: Renewable Energy Sources Act, Market Incentive Programme and Accompanying Ecological Research are the Federal Government's instruments to support biomass on its way to competitiveness on the energy market.
