    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

    In the twentieth century, vaccination has been possibly the greatest revolution in health. Together with hygiene and antibiotics, vaccination led to the elimination of many childhood infectious diseases and contributed to the increase in disability-free life expectancy that in Western societies rose from 50 to 78–85 years (Crimmins, E. M. & Finch, C. E. 2006 Proc. Natl Acad. Sci. USA 103, 498–503; Kirkwood, T. B. 2008 Nat. Med 10, 1177–1185). In the twenty-first century, vaccination will be expected to eliminate the remaining childhood infectious diseases, such as meningococcal meningitis, respiratory syncytial virus, group A streptococcus, and will address the health challenges of this century such as those associated with ageing, antibiotic resistance, emerging infectious diseases and poverty. However, for this to happen, we need to increase the public trust in vaccination so that vaccines can be perceived as the best insurance against most diseases across all ages. PMID:21893537

    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...

    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.

  15. Early twenty-first-century droughts during the warmest climate

    Directory of Open Access Journals (Sweden)

    Felix Kogan

    2016-01-01

    Full Text Available The first 13 years of the twenty-first century have begun with a series of widespread, long and intensive droughts around the world. Extreme and severe-to-extreme intensity droughts covered 2%–6% and 7%–16% of the world land, respectively, affecting environment, economies and humans. These droughts reduced agricultural production, leading to food shortages, human health deterioration, poverty, regional disturbances, population migration and death. This feature article is a travelogue of the twenty-first-century global and regional droughts during the warmest years of the past 100 years. These droughts were identified and monitored with the National Oceanic and Atmospheric Administration operational space technology, called vegetation health (VH, which has the longest period of observation and provides good data quality. The VH method was used for assessment of vegetation condition or health, including drought early detection and monitoring. The VH method is based on operational satellites data estimating both land surface greenness (NDVI and thermal conditions. The twenty-first-century droughts in the USA, Russia, Australia and Horn of Africa were intensive, long, covered large areas and caused huge losses in agricultural production, which affected food security and led to food riots in some countries. This research also investigates drought dynamics presenting no definite conclusion about drought intensification or/and expansion during the time of the warmest globe.

    2005-12-01

    With infection once again a high priority for the UK National Health Service (NHS), the medical microbiology and infection-control services require increased technology resources and more multidisciplinary staff. Clinical care and health protection need a coordinated network of microbiology services working to consistent standards, provided locally by NHS Trusts and supported by the regional expertise and national reference laboratories of the new Health Protection Agency. Here, I outline my thoughts on the need for these new resources and the ways in which clinical microbiology services in the UK can best meet the demands of the twenty-first century.

    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.

  18. Increasing precipitation volatility in twenty-first-century California

    Swain, Daniel L.; Langenbrunner, Baird; Neelin, J. David; Hall, Alex

    2018-05-01

    Mediterranean climate regimes are particularly susceptible to rapid shifts between drought and flood—of which, California's rapid transition from record multi-year dryness between 2012 and 2016 to extreme wetness during the 2016-2017 winter provides a dramatic example. Projected future changes in such dry-to-wet events, however, remain inadequately quantified, which we investigate here using the Community Earth System Model Large Ensemble of climate model simulations. Anthropogenic forcing is found to yield large twenty-first-century increases in the frequency of wet extremes, including a more than threefold increase in sub-seasonal events comparable to California's `Great Flood of 1862'. Smaller but statistically robust increases in dry extremes are also apparent. As a consequence, a 25% to 100% increase in extreme dry-to-wet precipitation events is projected, despite only modest changes in mean precipitation. Such hydrological cycle intensification would seriously challenge California's existing water storage, conveyance and flood control infrastructure.

  19. The Turn to Precarity in Twenty-First Century Fiction

    Directory of Open Access Journals (Sweden)

    Morrison Jago

    2014-01-01

    Full Text Available Recent years have seen several attempts by writers and critics to understand the changed sensibility in post-9/11 fiction through a variety of new -isms. This essay explores this cultural shift in a different way, finding a ‘turn to precarity’ in twenty-first century fiction characterised by a renewal of interest in the flow and foreclosure of affect, the resurgence of questions about vulnerability and our relationships to the other, and a heightened awareness of the social dynamics of seeing. The essay draws these tendencies together via the work of Judith Butler in Frames of War, in an analysis of Trezza Azzopardi’s quasi-biographical study of precarious life, Remember Me.

    Full Text Available This article explores some of the latest developments in the scholarship on race relations and nationalism that seek to address the impact of globalization and the changed geo-political relations of the first decade of the twenty-first century. New patterns of identification, some of which challenge existing group boundaries and others that reinforce them, can be seen to flow from the effects of global market changes and the political counter-movements against them. The impact of the “war on terrorism”, the limits of the utility of hard power, and the need for new mechanisms of inter-racial and inter-ethnic conflict resolution are evaluated to emphasize the complexity of these group relations in the new world disorder.

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

    Science.gov (United States)

    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.

  4. Nuclear energy into the twenty-first century

    Hammond, G.P.

    1996-01-01

    The historical development of the civil nuclear power generation industry is examined in the light of the need to meet conflicting energy-supply and environmental pressures over recent decades. It is suggested that fission (thermal and fast) reactors will dominate the market up to the period 2010-2030, with fusion being relegated to the latter part of the twenty-first century. A number of issues affecting the use of nuclear electricity generation in Western Europe are considered including its cost, industrial strategy needs, and the public acceptability of nuclear power. The contribution of nuclear power stations to achieving CO2 targets aimed at relieving global warming is discussed in the context of alternative strategies for sustainable development, including renewable energy sources and energy-efficiency measures. Trends in the generation of nuclear electricity from fission reactors are finally considered in terms of the main geopolitical groupings that make up the world in the mid-1990s. Several recent, but somewhat conflicting, forecasts of the role of nuclear power in the fuel mix to about 2020 are reviewed. It is argued that the only major expansion in generating capacity will take place on the Asia-Pacific Rim and not in the developing countries generally. Nevertheless, the global nuclear industry overall will continue to be dominated by a small number of large nuclear electricity generating countries; principally the USA, France and Japan. (UK)

    2014-04-01

    Clergy and religious leaders are facing a wide variety of sexual needs and concerns within their faith communities. Conflicts over sexual issues are growing across the entire spectrum of religious denominations, and clerics remain ill prepared to deal with them. As religious communities work to remain influential in public policy debates, clergy and the institutions that train them need to be properly prepared for twenty-first century challenges that impact sexuality and religion. Clergy are often the first point of contact for sexual problems and concerns of their faith community members-complex issues centered on morals, spirituality, and ethics. Yet, there still exists a significant lack of sexual curricula in the programs that are educating our future religious leaders. The resulting paucity of knowledge leaves these leaders unprepared to address the needs and concerns of their congregants. However, with accurate, relevant human sexuality curricula integrated into theological formation programs, future leaders will be equipped to competently serve their constituencies. This paper provides a rationale for the need for such training, an overview of the faith- and theology-based history of a pilot training project, and a description of how the Christian faith and the social sciences intersect in a training pilot project's impetus and process.

    1998-10-01

    The world's children comprise: (i) those in wealthy, industrialized countries; (ii) those from rapidly industrializing countries; (iii) minority groups including recently arrived immigrants in otherwise affluent and healthy societies; (iv) previously traditional people in rapid transition to urbanized, Western lifestyles; and (v) many millions living in grinding poverty in overcrowded, unhygienic conditions where child mortality is high and often due to malnutrition and infections. Industrialization, affluence, better housing, hygiene and nutrition, better clinical care and disease prevention have helped enhance child health in many countries over the past century. However, this is being offset by obesity, smoking, alcohol and drug abuse and social disruption, mental disease and high rates of violence including homicide and suicide. These 'new morbidities' are worse among minorities and in populations undergoing rapid social change. Social pressures including unemployment, depression and family dysfunction are important. Pediatricians must become active in decisions about the use of public resources in disease prevention, health education and more rational and equitable use of high technology. They should also be active advocates for children and their rights and advise governments about all issues that affect child health, protection and well-being. This is particularly so in the poorest and developing countries. There is a need for better international collaboration, training and exchange programs involving the International Pediatric Association, United Nations International Children's Emergency Fund, World Health Organization and other local, national and regional organizations to help overcome these problems as the next century draws near.

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

    Science.gov (United States)

    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.

    Bruett, Karen

    2006-01-01

    Public education is the key to individual and business prosperity. With a vested stake in education, educators, employers, parents, policymakers, and the public should question how this nation's public education system is faring. Knowing that recent international assessments have shown little or no gains in American students' achievement, the author asserts the clear need for change. As both a large American corporate employer and a provider of technology for schools, Dell is concerned with ensuring that youth will thrive in their adult lives. Changing workplace expectations lead to a new list of skills students will need to acquire before completing their schooling. Through technology, Dell supports schools in meeting educational goals, striving to supply students with the necessary skills, referred to as twenty-first century skills. The Partnership for 21st Century Skills, of which Dell is a member, has led an initiative to define what twenty-first century learning should entail. Through extensive research, the partnership has built a framework outlining twenty-first century skills: analytical thinking, communication, collaboration, global awareness, and technological and economic literacy. Dell and the partnership are working state by state to promote the integration of these skills into curricula, professional development for teachers, and classroom environments. The authors describe two current initiatives, one in Virginia, the other in Texas, which both use technology to help student learning. All stakeholders can take part in preparing young people to compete in the global economy. Educators and administrators, legislators, parents, and employers must play their role in helping students be ready for what the workforce and the world has in store for them.

  6. Ecological restoration should be redefined for the twenty-first century.

    Science.gov (United States)

    Martin, David M

    2017-09-24

    Forty years ago, ecological restoration was conceptualized through a natural science lens. Today, ecological restoration has evolved into a social and scientific concept. The duality of ecological restoration is acknowledged in guidance documents on the subject but is not apparent in its definition. Current definitions reflect our views about what ecological restoration does but not why we do it. This viewpoint does not give appropriate credit to contributions from social sciences, nor does it provide compelling goals for people with different motivating rationales to engage in or support restoration. In this study, I give a concise history of the conceptualization and definition of ecological restoration, and I propose an alternative definition and corresponding viewpoint on restoration goal-setting to meet twenty-first century scientific and public inquiry.

    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

    Niels Bohr and Philosophy of Physics: Twenty-First Century Perspectives examines the philosophical views, influences and legacy of the Nobel Prize physicist and philosophical spokesman of the quantum revolution, Niels Bohr. The sixteen contributions in this collection by some of the best contemporary philosophers and physicists writing on Bohr's philosophy today all carefully distinguish his subtle and unique interpretation of quantum mechanics from views often imputed to him under the banner of the “Copenhagen Interpretation.” With respect to philosophical influences on Bohr's outlook, the contributors analyse prominent similarities between his viewpoint and Kantian ways of thinking, the views of the Danish philosopher Harald Høffding, and themes characteristic of American pragmatism. In recognizing the importance of Bohr's epistemological naturalism they examine his defence of the indispensability of classical concepts from a variety of different perspectives. This collection shows us that Bohr's int...

    At the beginning of the twenty-first century, there are 30,000 golf courses and 55 million people who play golf worldwide. In the USA alone, the value of golf club memberships sold in the 1990s was US dollar 3.2 billion. Underpinning this significant human activity is a wide variety of people researching and applying science to sustain and develop the game. The 11 golf science disciplines recognized by the World Scientific Congress of Golf have reported 311 papers at four world congresses since 1990. Additionally, scientific papers have been published in discipline-specific peer-reviewed journals, research has been sponsored by the two governing bodies of golf, the Royal and Ancient Golf Club of St. Andrews and the United States Golf Association, and confidential research is undertaken by commercial companies, especially equipment manufacturers. This paper reviews much of this human endeavour and points the way forward for future research into golf.

    2016-01-01

    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.

  11. Uncertainty in Twenty-First-Century CMIP5 Sea Level Projections

    Little, Christopher M.; Horton, Radley M.; Kopp, Robert E.; Oppenheimer, Michael; Yip, Stan

    2015-01-01

    The representative concentration pathway (RCP) simulations included in phase 5 of the Coupled Model Intercomparison Project (CMIP5) quantify the response of the climate system to different natural and anthropogenic forcing scenarios. These simulations differ because of 1) forcing, 2) the representation of the climate system in atmosphere-ocean general circulation models (AOGCMs), and 3) the presence of unforced (internal) variability. Global and local sea level rise projections derived from these simulations, and the emergence of distinct responses to the four RCPs depend on the relative magnitude of these sources of uncertainty at different lead times. Here, the uncertainty in CMIP5 projections of sea level is partitioned at global and local scales, using a 164-member ensemble of twenty-first-century simulations. Local projections at New York City (NYSL) are highlighted. The partition between model uncertainty, scenario uncertainty, and internal variability in global mean sea level (GMSL) is qualitatively consistent with that of surface air temperature, with model uncertainty dominant for most of the twenty-first century. Locally, model uncertainty is dominant through 2100, with maxima in the North Atlantic and the Arctic Ocean. The model spread is driven largely by 4 of the 16 AOGCMs in the ensemble; these models exhibit outlying behavior in all RCPs and in both GMSL and NYSL. The magnitude of internal variability varies widely by location and across models, leading to differences of several decades in the local emergence of RCPs. The AOGCM spread, and its sensitivity to model exclusion and/or weighting, has important implications for sea level assessments, especially if a local risk management approach is utilized.

  12. 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.

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

    Science.gov (United States)

    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.

    Extensive and rapid losses of sea ice in the Arctic have raised conservation concerns for the Pacific walrus (Odobenus rosmarus divergens), a large pinniped inhabiting arctic and subarctic continental shelf waters of the Chukchi and Bering seas. We developed a Bayesian network model to integrate potential effects of changing environmental conditions and anthropogenic stressors on the future status of the Pacific walrus population at four periods through the twenty-first century. The model framework allowed for inclusion of various sources and levels of knowledge, and representation of structural and parameter uncertainties. Walrus outcome probabilities through the century reflected a clear trend of worsening conditions for the subspecies. From the current observation period to the end of century, the greatest change in walrus outcome probabilities was a progressive decrease in the outcome state of robust and a concomitant increase in the outcome state of vulnerable. The probabilities of rare and extirpated states each progressively increased but remained level of 10% in 2004 to 22% by 2050 and 40% by 2095. The degree of uncertainty in walrus outcomes increased monotonically over future periods. In the model, sea ice habitat (particularly for summer/fall) and harvest levels had the greatest influence on future population outcomes. Other potential stressors had much smaller influences on walrus outcomes, mostly because of uncertainty in their future states and our current poor understanding of their mechanistic influence on walrus abundance.

    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.

    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.

Although the decadal-to-centennial response to atmospheric CO2 and climate change is constrained by observations and models1, 9, little is known about corresponding changes in seasonality10-12, particularly for pH. Here we assess the latter by analysing nine earth system models (ESMs) forced with a business-as-usual emissions scenario13. During the twenty-first century, the seasonal cycle of surface-ocean pH was attenuated by 16 ± 7%, on average, whereas that for hydrogen ion concentration [H+] was amplified by 81 ± 16%. Simultaneously, the seasonal amplitude of the aragonite saturation state (Ωarag) was attenuated except in the subtropics, where it was amplified. These contrasting changes derive from regionally varying sensitivities of these variables to atmospheric CO2 and climate change and to diverging trends in seasonal extremes in the primary controlling variables (temperature, dissolved inorganic carbon and alkalinity). Projected seasonality changes will tend to exacerbate the impacts of increasing [H+] on marine organisms during the summer and ameliorate the impacts during the winter, although the opposite holds in the high latitudes. Similarly, over most of the ocean, impacts from declining Ωarag are likely to be intensified during the summer and dampened during the winter.

    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...

    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.

    There are many opportunities and challenges for conducting occupational epidemiologic studies today. In this paper, we summarize the discussion of a symposium held at the Epidemiology in Occupational Health (EPICOH) conference, Chicago 2014, on challenges for occupational epidemiology in the twenty-first century. The increasing number of publications and attendance at our conferences suggests that worldwide interest in occupational epidemiology has been growing. There are clearly abundant opportunities for new research in occupational epidemiology. Areas ripe for further work include developing improved methods for exposure assessment, statistical analysis, studying migrant workers and other vulnerable populations, the use of biomarkers, and new hazards. Several major challenges are also discussed such as the rapidly changing nature and location of work, lack of funding, and political/legal conflicts. As long as work exists there will be occupational diseases that demand our attention, and a need for epidemiologic studies designed to characterize these risks and to support the development of preventive strategies. Despite the challenges and given the important past contribution in this field, we are optimistic about the importance and continued vitality of the research field of occupational epidemiology.

    The twenty-first in a series of nuclear accident dosimetry (NAD) intercomparison (NAD) studies was conducted at the Oak Ridge National Laboratory's Dosimetry Applications Research Facility during August 6-10, 1984. The Health Physics Research Reactor operated in the pulse mode was used to simulate three criticality accidents with different radiation fields. Participants from five organizations measured neutron doses between 0.53 and 4.36 Gy and gamma doses between 0.19 and 1.01 Gy at area monitoring stations and on phantoms. About 75% of all neutron dose estimates based on foil activation, hair activation, simulated blood sodium activation, and thermoluminescent methods were within +-25% of reference values. Approximately 86% of all gamma results measured using thermoluminescent (TLD-700 or CaSO 4 ) systems were within +-20% of reference doses which represents a significant improvement over previous studies. Improvements observed in the ability of intercomparison participants to estimate neutron and gamma doses under criticality accident conditions can be partly attributed to experience in previous NAD studies which have provided practical tests of dosimetry systems, enabled participants to improve evaluation methods, and standardized dose reporting conventions. 16 refs., 15 tabs

    During the spring and summer months of 1987, the Aero Propulsion Laboratory of the Air Force Wright Aeronautical Laboratories, Wright-Patterson AFB, Ohio in cooperation with the Air Force Space Technology Center at Kirtland AFB, New Mexico, undertook an initiative to develop a Strategic Plan for Space Power Technology Development. The initiative was called SPT21, Space Power Technology for the Twenty-First Century. The planning process involved the participation of other Government organizations (U.S. Army, Navy, DOE and NASA) along with major aerospace companies and universities. Following an SPT21 kickoff meeting on 28 May 1987, detailed strategic planning was accomplished through seven (7) Space Power Technology Discipline Workshops commencing in June 1987 and concluding in August 1987. Technology Discipline Workshops were conducted in the following areas: (1) Solar Thermal Dynamic Power Systems (2) Solar Photovoltaic Cells and Arrays (3) Thermal Management Technology (4) Energy Storage Technology (5) Nuclear Power Systems Technology (6) Power Conditioning, Distribution and Control and (7) Systems Technology/Advanced Concepts. This technical paper summarizes the planning process and describes the salient findings and conclusions of the workshops

    Full Text Available The Baltic Sea, one of the world’s largest semi-enclosed seas, which, with its very low salinity and quasi-isolation from the big oceans cannot decide whether it is a sea or a large lake. This geologically-unique environment supports an even more surprising and delicate marine ecosystem, where a complex community of fishes, marine mammals and important microscopic organisms creates a magical mosaic of life. Humans have enjoyed the abundance of life in the Baltic Sea for thousands of years, and major Scandinavian and Baltic cities have oriented themselves towards this geo-ecosystem in order to develop and seek ecological, economical and cultural inspiration and wealth. The ‘Mosaic of Life’ workshop aimed at going beyond the obvious in examining the meaning of the Baltic Sea by gathering together a selection of young, creative minds from different backgrounds ranging from the arts and economics to geology and life sciences. This intensive workshop was designed as a unique training opportunity to develop essential twenty-first century skills – to introduce and develop creative, critical and interdisciplinary thinking and collaborative teamwork, as well as to foster a visual and scientific literacy, using project-based learning and hands-on activities. Our final goal has been to be inspired by the resulting connections, differences and unifying concepts, creating innovative, interdisciplinary projects which would look further than the sea – further than the eye can see and further into the future.

  4. Twenty-first century learning in schools: A case study of New Technology High School in Napa, California.

    2006-01-01

    The most pertinent question concerning teaching and learning in the twenty-first century is not what knowledge and skills students need--that laundry list was identified over a decade ago--but rather how to foster twenty-first century learning. What curricula, experiences, assessments, environments, and technology best support twenty-first century learning? New Technology High School (NTHS) in Napa, California, is one example of a successful twenty-first century school. In this chapter, the author describes the components of this exemplary high school, illustrating an environment that will cultivate twenty-first century student learning. New Technology High School began by defining eight learning outcomes, aligned with the standards of the Partnership for 21st Century Skills; to graduate, students demonstrate mastery of these outcomes through an online portfolio. To help students achieve the outcomes, NTHS employs project- and problem-based learning. Whereas in traditional classrooms students work alone on short-term assignments that do not lend themselves to deep understanding, the project-based learning approach has students working in teams on long-term, in-depth, rigorous projects. Students' work is supported by the school's workplace-like environment and effectiv use of technology. Meaningful assessment is essential to project-based learning; students receive continuous feedback, helping them become self-directed learners. In fact, NTHS uses outcome-based grading through which students constantly know how they are performing on the twenty-first century outcomes. Research has shown that NTHS graduates are better prepared for postsecondary education, careers, and citizenship than their peers from other schools. To facilitate twenty-first century learning, all schools need to rethink their approach to teaching and learning. New Technology High School is one way to do so.

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

    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.

    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

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

    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. © London School of Economics and Political Science 2014.

  8. 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

    Full Text Available In accord with the promise made by Henry Jenkins that “old and new media will interact in ever more complex ways” (Convergence Culture 6, this research observes metamodern fairy tale adaptations of the twenty-first century in light of Christina Bacchilega’s construct of the fairy-tale web and Henry Jenkins’ theory of convergence culture and transmedia storytelling. The research will address the growing trend of embedding “wonder tale” collections within the context of a larger narrative as an artefact of significance, power, and material value. Although original tales with known authorship, these fairy tale adaptations are appended to the mythology and culture of the fantastic secondary worlds. Such texts tend to be parodic, subversive, and even carnivalesque (Bakhtin; Stephens, providing a commentary on the culture of their origin, as well as our own. By blending cultures, styles, and formats, mise en abyme wonder tales also result in the empowerment of specifically marginalised groups. Generally defined as spin-offs that are otherwise a part of a complex inter- and hypertextual web, these fairy tale collections constitute a metafictional body of knowledge and wisdom. In the digital era much focus is placed on multimodal, hypertextual, and transmedia narratives with a significant influence of fandom on the production of such literary works. The study will focus on the popular examples of such practice, J.K. Rowling’s Tales of Beedle the Bard (2007/2008 and Ransom Riggs’ Tales of the Peculiar (2016, in order to define mise en abyme fairy tale adaptations, as well as to discuss their cultural significance and function.

    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.

    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.

    Using the set of simulations performed with atmosphere-ocean general circulation models (AOGCMs) for the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR4), the projected regional distribution of sea ice for the twenty-first century has been investigated. Averaged over all those model simulations, the current climate is reasonably well reproduced. However, this averaging procedure hides the errors from individual models. Over the twentieth century, the multimodel average simulates a larger sea-ice concentration decrease around the Antarctic Peninsula compared to other regions, which is in qualitative agreement with observations. This is likely related to the positive trend in the Southern Annular Mode (SAM) index over the twentieth century, in both observations and in the multimodel average. Despite the simulated positive future trend in SAM, such a regional feature around the Antarctic Peninsula is absent in the projected sea-ice change for the end of the twenty-first century. The maximum decrease is indeed located over the central Weddell Sea and the Amundsen-Bellingshausen Seas. In most models, changes in the oceanic currents could play a role in the regional distribution of the sea ice, especially in the Ross Sea, where stronger southward currents could be responsible for a smaller sea-ice decrease during the twenty-first century. Finally, changes in the mixed layer depth can be found in some models, inducing locally strong changes in the sea-ice concentration. (orig.)

    2017-06-01

    Full Text Available Public health in twenty-first century Ghana is mired with several issues ranging from the inadequacy of public health facilities, improper settlement planning, insanitary conditions, and the inadequacy of laws and their implementation. This situation compared to the colonial era is a direct contradiction. Development in the pre-colonial era to the colonial era sought to make the prevention of diseases a priority in the colonial administration. This was begun with the establishment of the health branch in 1909 as a response to the bubonic plague that was fast spreading in the colony. From here public health policies and strategies were enacted to help the diseases prevention cause. Various public health boards, the medical research institute or the laboratory branch, the waste management department, the use of preventive medicine and maintenance of good settlement planning and sanitation were public health measures in the colonial era. This research seeks to analyse the public health system in the colonial era so as to draw basic lessons for twenty-first century Ghana. Archival data and other secondary sources are reviewed and analysed to help draw these lessons. Richard Rose’s lesson-drawing approach was used to draw the lessons.

    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

    Full Text Available Twenty-first century education has undoubtedly witnessed changes of the definition of literacy to cope with the economic, social, and intellectual trends. Technological advances, which include skills of communication, creativity, critical thinking, and collaboration have become key in education, especially when dealing with literacy and reading motivation. As motivation hinges around two major theoretical approaches, intrinsic and extrinsic, numerous studies argue for the first to be more sustainable in enhancing reading motivation. Accordingly, many research-based interventional programs have emerged since the late nineties with increasing popularity to offer answers to the dwindling rates in reading among youth. This article discusses traits of 21st century education in light of trends and challenges as it probes the effectiveness of some interventional programs that are meant, and argued for, to enhance literacy skills and reading motivation.

  15. Us, them, and others: reflections on Canadian multiculturalism and national identity at the turn of the twenty-first century.

    Winter, Elke

    2014-05-01

    The John Porter Lecture at the annual meeting of the Canadian Sociological Association in Victoria 2013 draws upon my book Us, Them, and Others: Pluralism and National Identity in Diverse Societies. Incorporating the findings from an analysis of Canadian English-language newspaper discourses during the 1990s into a theoretical framework inspired by Weberian sociology, the book argues that pluralism is best understood as a dynamic set of triangular relations where the compromise between unequal groups--"us" and "others"--is rendered meaningful through the confrontation with real or imagined outsiders ("them"). The lecture summarizes the theoretical contribution and explains how multiculturalism became consolidated in dominant Canadian discourses in the late 1990s. The lecture then discusses changes to Canadian multicultural identity at the beginning of the twenty-first century.

    2014-10-01

    This paper highlights the specific manner in which twenty-first-century horror films stigmatize psychosis and mental health care environments (MHCEs) A search on various film forums using the terms "mental/psychiatric patient," "psychosis/psychoses," and "mental/psychiatric hospital" (limited from 2000 to 2012) revealed 55 films. A literature review revealed criteria for a checklist. Subsequent to viewings, salient recurring criteria were added to the checklist. Films were systematically analyzed under these criteria. Homicidal maniacs are the most common stereotypes. Misinformation is often communicated. Familiar horror tropes are used to stigmatize MHCEs. Practitioners should be aware of the specific manner in which clients are being stigmatized by the media. This paper highlights specific ways in which psychosis and MHCEs are stigmatized, and encourages practitioners to challenge these depictions. © 2013 Wiley Periodicals, Inc.

  17. Towards a Rational Kingdom in Africa: Knowledge, Critical Rationality and Development in a Twenty-First Century African Cultural Context

    Directory of Open Access Journals (Sweden)

    Lawrence Ogbo Ugwuanyi

    2018-03-01

    Full Text Available This paper seeks to locate the kind of knowledge that is relevant for African development in the twenty-first century African cultural context and to propose the paradigm for achieving such knowledge. To do this, it advances the view that the concept of twenty-first century in an African context must be located with the colonial and post-colonial challenges of the African world and applied to serve the African demand. Anchored on this position, the paper outlines and critiques the wrong assumption on which modern state project was anchored in post-colonial Africa and its development dividend to suggest that this is an outcome of a wrong knowledge design that is foundational to the state project and which the project did not address. It proposes a shift in the knowledge paradigm in Africa and suggests critical self-consciousness as a more desirable knowledge design for Africa. It applies the term ‘rational kingdom’ (defined as a community of reason marked by critical conceptual self-awareness driven by innovation and constructivism to suggest this paradigm. ‘Innovation’ is meant as the application of reason with an enlarged capacity to anticipate and address problems with fresh options and ‘constructivism’ is meant as the disposition to sustain innovation by advancing an alternative but more reliable worldview that can meet the exigencies of modernity in an African cultural context. The paper then proceeds to outline the nature of the rational kingdom and its anticipated gains and outcomes. It applies the method of inductive reasoning to advance its position. To do this it invokes selected but crucial areas of African life to locate how the developmental demands of these aspects of life suggest a critical turn in African rationality.

    The global wave-induced current (the Stokes Drift - SD) is an important feature of the ocean surface, with mean values close to 10 cm/s along the extra-tropical storm tracks in both hemispheres. Besides the horizontal displacement of large volumes of water the SD also plays an important role in the ocean mix-layer turbulence structure, particularly in stormy or high wind speed areas. The role of the wave-induced currents in the ocean mix-layer and in the sea surface temperature (SST) is currently a hot topic of air-sea interaction research, from forecast to climate ranges. The SD is mostly driven by wind sea waves and highly sensitive to changes in the overlaying wind speed and direction. The impact of climate change in the global wave-induced current climate will be presented. The wave model WAM has been forced by the global climate model (GCM) ECHAM5 wind speed (at 10 m height) and ice, for present-day and potential future climate conditions towards the end of the end of the twenty-first century, represented by the Intergovernmental Panel for Climate Change (IPCC) CMIP3 (Coupled Model Inter-comparison Project phase 3) A1B greenhouse gas emission scenario (usually referred to as a ''medium-high emissions'' scenario). Several wave parameters were stored as output in the WAM model simulations, including the wave spectra. The 6 hourly and 0.5°×0.5°, temporal and space resolution, wave spectra were used to compute the SD global climate of two 32-yr periods, representative of the end of the twentieth (1959-1990) and twenty-first (1969-2100) centuries. Comparisons of the present climate run with the ECMWF (European Centre for Medium-Range Weather Forecasts) ERA-40 reanalysis are used to assess the capability of the WAM-ECHAM5 runs to produce realistic SD results. This study is part of the WRCP-JCOMM COWCLIP (Coordinated Ocean Wave Climate Project) effort.

  1. 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)

    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

    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.

  3. Watershed-scale response to climate change through the twenty-first century for selected basins across the United States

    The hydrologic response of different climate-change emission scenarios for the twenty-first century were evaluated in 14 basins from different hydroclimatic regions across the United States using the Precipitation-Runoff Modeling System (PRMS), a process-based, distributed-parameter watershed model. This study involves four major steps: 1) setup and calibration of the PRMS model in 14 basins across the United States by local U.S. Geological Survey personnel; 2) statistical downscaling of the World Climate Research Programme’s Coupled Model Intercomparison Project phase 3 climate-change emission scenarios to create PRMS input files that reflect these emission scenarios; 3) run PRMS for the climate-change emission scenarios for the 14 basins; and 4) evaluation of the PRMS output.This paper presents an overview of this project, details of the methodology, results from the 14 basin simulations, and interpretation of these results. A key finding is that the hydrological response of the different geographical regions of the United States to potential climate change may be very different, depending on the dominant physical processes of that particular region. Also considered is the tremendous amount of uncertainty present in the climate emission scenarios and how this uncertainty propagates through the hydrologic simulations. This paper concludes with a discussion of the lessons learned and potential for future work.

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

    Directory of Open Access Journals (Sweden)

    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.

    Strong growth of interdisciplinary sciences might find exceptional example in academic health economics. We decided to observe the quantitative output in this science since the beginning of the twenty-first century. Electronic search of the published literature was conducted in four different databases: one medical database-MEDLINE/PubMed, two general databases-Scopus/Elsevier and Web of Science (WoS), and one specialized health economic database-NHS Economic Evaluation Database (EED). The applied combination of key words was carefully chosen to cover the most commonly used terms in titles of publications dealing with conceptual areas of health economics. All bibliographic units were taken into account. Within the time horizon from January 1, 2000 to December 31, 2016, without language or limitations on bibliographic unit types, we identified an output ranging approximately from 60,345 to 88,246 records with applied search strategy in MEDLINE/PubMed, Scopus/Elsevier, and WoS. In NHS EED, we detected 14,761 records of economic evaluations of health interventions during the period in which database was maintained and regularly updated. With slightly more than one-third of the identified records, USA clearly dominates in this field. United Kingdom takes a strong second place with about 12% of identified records. Consistently, USA and UK universities are the most frequent among the top 15 affiliations/organizations of the authors of the identified records. Authors from Harvard University contributed to the largest number of the identified records. There is a clear evidence of both the upward stream of blossoming in health economics publications and its acceleration. Based on this bibliographic data set, it is difficult to distinguish the actual impact growth of this output provided dominantly by academia with modest contribution by pharmaceutical/medicinal device industry and diverse national government-based agencies.

  6. Agriculture in West Africa in the Twenty-First Century: Climate Change and Impacts Scenarios, and Potential for Adaptation

    Sultan, Benjamin; Gaetani, Marco

    2016-01-01

    West Africa is known to be particularly vulnerable to climate change due to high climate variability, high reliance on rain-fed agriculture, and limited economic and institutional capacity to respond to climate variability and change. In this context, better knowledge of how climate will change in West Africa and how such changes will impact crop productivity is crucial to inform policies that may counteract the adverse effects. This review paper provides a comprehensive overview of climate change impacts on agriculture in West Africa based on the recent scientific literature. West Africa is nowadays experiencing a rapid climate change, characterized by a widespread warming, a recovery of the monsoonal precipitation, and an increase in the occurrence of climate extremes. The observed climate tendencies are also projected to continue in the twenty-first century under moderate and high emission scenarios, although large uncertainties still affect simulations of the future West African climate, especially regarding the summer precipitation. However, despite diverging future projections of the monsoonal rainfall, which is essential for rain-fed agriculture, a robust evidence of yield loss in West Africa emerges. This yield loss is mainly driven by increased mean temperature while potential wetter or drier conditions as well as elevated CO2 concentrations can modulate this effect. Potential for adaptation is illustrated for major crops in West Africa through a selection of studies based on process-based crop models to adjust cropping systems (change in varieties, sowing dates and density, irrigation, fertilizer management) to future climate. Results of the cited studies are crop and region specific and no clear conclusions can be made regarding the most effective adaptation options. Further efforts are needed to improve modeling of the monsoon system and to better quantify the uncertainty in its changes under a warmer climate, in the response of the crops to such

  7. The traditional commons of England and Wales in the twenty-first century: meeting new and old challenges

    Directory of Open Access Journals (Sweden)

    2008-07-01

    Full Text Available The commons literature makes much of the changes within the traditional land use sectors of developed countries. This largely focuses on the decline of the economic function of commons that threaten their existence, the emergence of multiple use patterns, and the resilience and policy adaptation needed to continue. The situation in England and Wales is used to illustrate that commons are increasingly important to a number of ‘new’ rural functions and that the associated policy developments may hold an important message for progress towards sustainable multifunctional land management more generally. This article reviews and updates what is meant by the term common land within England and Wales, while outlining its current importance and threats. The commons literature is investigated to see if the approach is useful in revealing the current issues associated with the incorporation of new stakeholders and functions within a traditional structure. Recent changes and developments surrounding the Commons Act 2006 are assessed to see if they are likely to assist in sustaining these commons through the twenty-first century. The article argues that any new approach requires long term planning and a commitment to support local participation among commoners and others who are involved in the governance and management of these areas of land. In order for these challenges to be met there needs to be an understanding of the functions and cultural traditions of common land as well as of the changes in society associated with the decline in traditional agrarian management in developed countries. Such challenges can rarely if ever be achieved through legislation and policy developments, requiring an investment in developing locally based solutions.

    The Chácobo are a Panoan speaking tribe of about 1000 members (300+ adults) in Beni, Bolivia. Originally nomadic, the Chácabo were relocated to their current main location in the 1960s. Researchers have visited the Chácabo since 1911. A first more detailed anthropological report exists from the late 1960s, and ecological-ethnobotanical studies were conducted in the 1980s and 1990s. The presented work represents a complete ethnobotanical inventory of the entire adult Chácobo population, with interviews and plant collection conducted directly by Chácobo counterparts. Based on previous reports and our preliminary studies, we hypothesized that twenty-first century Chácobo plant use centered on income generation, and that traditional plant use related to household utensils, medicine and traditional crop varieties had almost disappeared. To test this hypothesis, we started the "Chácobo Ethnobotany Project," training 10 indigenous Chácobo participants in ethnobotanical interview and plant collection techniques, in order to more fully document Chácobo knowledge and avoid the influence of foreign interviewers. Our study found 331 useful plant species in 241genera of 95 plant families, with leaves, roots and bark being the most commonly used plant parts The comprehensive documentation that these methods enabled completely nullified our initial hypothesis of knowledge loss. Traditional crop varieties are still widely grown and traditional knowledge is alive. Moreover, it is being actively recuperated in certain domains by the younger generation. Most Chácobo know, and can name, traditional utensils and tools, although only the older generation has still the skills to manufacture them. While many Chácobo still know the names and uses of medicinal species, the younger generation is however often unsure how to identify them. In this paper we illustrate the complexity of perspectives on knowledge at different ages, and the persistence of knowledge over almost a century

  9. 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

    The Southeast US (SEUS) has long been recognized as a region where the climatic effect of atmospheric aerosols can cool the Earth and have thus reduced the effect of greenhouse warming. However, previous studies have assessed that abundant carbonaceous aerosols over SEUS from a combination of anthropogenic and natural sources are systematically underestimated by most atmospheric models, especially during summer when the average carbon concentration in SEUS is the highest in the country. In this study, we utilize an ensemble of surface (AERONET) and satellite (MISR, CALIPSO) observations over the SEUS from 2001 to 2015 to better understand the spatially and vertically-resolved decadal trend of SEUS aerosol burden. Results from CALIOP show significant aerosol loading extending from the surface to 5km year-round. Additionally, these data show aerosol extinction coefficients as large as 0.01 km-1 extending well above 8km during the summertime. CALIOP measurements corroborate seasonal observations from MISR and indicate that much of the aerosol burden in the SEUS is comprised of smoke, polluted continental and polluted dust species. Using boundary layer heights from the ERA Interim dataset, CALIOP data show that while summertime aerosol burden above the boundary layer (elevated) is equal to about half of the AOD in the surface layer (0.17 vs. 0.08), during wintertime, the vast majority of aerosols are below the boundary layer (0.12 vs. 0.03). Despite strong seasonality in overall aerosol burden, decadal trends in AOD did not exhibit similarly large seasonal differences; data show AOD decreasing between 2001 and 2015 during both summer and winter and in both the MISR and CALIOP datasets. Between 2001 and 2015, the average summertime aerosol optical depth (AOD) from MISR fell from 0.23 to 0.15, and the trend was -0.05 decade-1 (23% decade-1). The fit was statistically significant, with an r2=0.53. Measurement campaigns such as SEAC4RC will be extensively leveraged, which

    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.

    Full Text Available One hundred and ten years ago, men and women took constitutionalism to achieve justice in Iran. National Council was the result of the Iranian people's struggle for justice, both women and men. Men policies from the beginning of legislation put women as minors and lunatics and bankrupted and banned them from vote. However, the Constitutional Revolution as a turning point and a national revolution played a key role in changing attitudes to women and structural context of their participation provided. In this paper, with the use of descriptive-analytical as well as quantitative methods, we sought to answer the question that what was the position of women in the twenty-first Parliament. The results of this study suggest that when Iranian women were allowed to participate politics, they have achieved to show their ability in politics as we saw examples in the twenty-first Parliament in which women had twenty-two percent participation.

    The fourth version of the atmosphere-ocean general circulation (AOGCM) model developed at the Institut Pierre-Simon Laplace (IPSL-CM4) is used to investigate the mechanisms influencing the Arctic freshwater balance in response to anthropogenic greenhouse gas forcing. The freshwater influence on the interannual variability of deep winter oceanic convection in the Nordic Seas is also studied on the basis of correlation and regression analyses of detrended variables. The model shows that the Fram Strait outflow, which is an important source of freshwater for the northern North Atlantic, experiences a rapid and strong transition from a weak state toward a relatively strong state during 1990-2010. The authors propose that this climate shift is triggered by the retreat of sea ice in the Barents Sea during the late twentieth century. This sea ice reduction initiates a positive feedback in the atmosphere-sea ice-ocean system that alters both the atmospheric and oceanic circulations in the Greenland-Iceland-Norwegian (GIN)-Barents Seas sector. Around year 2080, the model predicts a second transition threshold beyond which the Fram Strait outflow is restored toward its original weak value. The long-term freshening of the GIN Seas is invoked to explain this rapid transition. It is further found that the mechanism of interannual changes in deep mixing differ fundamentally between the twentieth and twenty-first centuries. This difference is caused by the dominant influence of freshwater over the twenty-first century. In the GIN Seas, the interannual changes in the liquid freshwater export out of the Arctic Ocean through Fram Strait combined with the interannual changes in the liquid freshwater import from the North Atlantic are shown to have a major influence in driving the interannual variability of the deep convection during the twenty-first century. South of Iceland, the other region of deep water renewal in the model, changes in freshwater import from the North Atlantic

    Full Text Available The EU CAP has developed immensely since the 1960’s. However, its current determinants are completely different from those which formed the CAP foundations. This results mainly from the fact that the UE CAP must meet present-day challenges and threats. Moreover, further EU enlargements also significantly influenced performance of this sector of economy. It is important to determine whether the existence of the CAP in the twenty-first century still makes sense and to specify in more detail the CAP reform directions after 2013 from the perspective of Poland and Hungary.

  5. A Conservation Ethic and the Collecting of Animals by Institutions of Natural Heritage in the Twenty-First Century: Case Study of the Australian Museum

    2011-02-01

    Full Text Available Collecting of animals from their habitats for preservation by museums and related bodies is a core operation of such institutions. Conservation of biodiversity in the current era is a priority in the scientific agendas of museums of natural heritage in Australia and the world. Intuitively, to take animals from the wild, while engaged in scientific or other practices that are supposed to promote their ongoing survival, may appear be incompatible. The Australian Museum presents an interesting ground to consider zoological collecting by museums in the twenty-first century. Anderson and Reeves in 1994 argued that a milieu existed that undervalued native species, and that the role of natural history museums, up to as late as the mid-twentieth century, was only to make a record the faunal diversity of Australia, which would inevitably be extinct. Despite the latter, conservation of Australia’s faunal diversity is a key aspect of research programmes in Australia’s institutions of natural heritage in the current era. This paper analyses collecting of animals, a core task for institutions of natural heritage, and how this interacts with a professed “conservation ethic” in a twenty-first century Australian setting.

    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.

  8. How Has Elderly Migration Changed in the Twenty-First Century? What the Data Can-and Cannot-Tell Us.

    2016-08-01

    Interstate elderly migration has strong implications for state tax policies and health care systems, yet little is known about how it has changed in the twenty-first century. Its relative rarity requires a large data set with which to construct reliable measures, and the replacement of the U.S. Census long form (CLF) with the American Community Survey (ACS) has made such updates difficult. Two commonly used alternative migration data sources-the Current Population Survey (CPS) and the Statistics of Income (SOI) program of the Internal Revenue Service (IRS)-suffer serious limitations in studying the migration of any subpopulation, including the elderly. Our study informs migration research in the post-2000 era by identifying methodological differences between data sources and devising strategies for reconciling the CLF and ACS. Our investigation focusing on the elderly suggests that the ACS can generate comparable migration data that reveal a continuation of previously identified geographic patterns as well as changes unique to the 2000s. However, its changed definition of residence and survey timing leaves us unable to construct a comparable national migration rate, suggesting that one must use national trends in the smaller CPS to investigate whether elderly migration has increased or decreased in the twenty-first century.

  9. Wicked Female Characters in Roddy Doyle’s “The Pram”: Revisiting Celtic and Polish Myths in the Context of Twenty-First Century Ireland

    2015-07-01

    Full Text Available “The Pram” is the only horror story in Roddy Doyle’s collection The Deportees and Other Stories (2007. It is also unique in terms of its approach to Ireland’s multicultural scene in the twenty-first century. Doyle turns the other side of the coin and introduces a migrant caretaker (Alina, who loses her mind due to her employees’ (the O’Reilly family ill-treatment. As a reaction to their scornful attitude, Alina becomes a murderer. Set in the context of twenty-first century Dublin, “The Pram” contains various references to Celtic and Polish mythological female figures (in particular, the Old Hag of Beara and Boginka, which strengthen the thrilling, mythical elements in the plot. This paper aims to examine the characters’ negative attitude towards migrants in Ireland in the light of the racist discourse present in the story. Also, I will focus on the story’s female characters and discuss the handicaps of being a female migrant in Ireland. The parallels between the mythical female figures and the protagonist Alina will be another point to be analyzed. The argument of this paper is that Doyle does not always portray the positive outcomes of a multicultural society. On the contrary, he conveys the perspective of the incoming migrant. “The Pram” stages the obstacles that a female outsider may experience in Ireland and her subsequent transformation as a result of the racism she encounters there.

  10. Consideration of land-use and land-cover changes in the projection of climate extremes over North America by the end of the twenty-first century

    2018-03-01

    Changes in the essential climate extremes indices and surface variables for the end of the twenty-first century are assessed in this study based on two transient climate change simulations, with and without land-use and land-cover changes (LULCC), but identical atmospheric forcing. The two simulations are performed with the 5th generation of the Canadian Regional Climate Model (CRCM5) driven by the Canadian Earth System Model for the (2006-2100)-Representative Concentration Pathway 4.5 (RCP4.5) scenario. For the simulation with LULCC, land-cover data sets are taken from the global change assessment model (GCAM) representing the RCP4.5 scenario for the period 2006-2100. LULCC in RCP4.5 scenario suggest significant reduction in cultivated land (e.g. Canadian Prairies and Mississippi basin) due to afforestation. CRCM5 climate projections imply a general warming by the end of the twenty-first century, especially over the northern regions in winter. CRCM5 projects more warm spell-days per year over most areas of the continent, and implicitly more summer days and tropical nights at the expense of cold-spell, frost and ice days whose number is projected to decrease by up to 40% by the end of the twenty-first century with respect to the baseline period 1971-2000. Most land areas north of 45°N, in all seasons, as well as the southeastern United States in summer, exhibit increases in mean precipitation under the RCP4.5 scenario. In contrast, central parts of the continent in summer and much of Mexico in all seasons show reduced precipitation. In addition, large areas of North America exhibit changes of 10 to 40% (depending on the season and geographical location) in the number of heavy precipitation days. Results also suggest that the biogeophysical effects of LULCC on climate, assessed through differences between the two simulations, lead to warmer regional climates, especially in winter. The investigation of processes leading to this response shows high sensitivity of the

    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.

    This study examines the shifts in terrestrial climate regimes using the Köppen-Trewartha (K-T) climate classification by analyzing the Community Earth System Model Last Millennium Ensemble (CESM-LME) simulations for the period 850-2005 and CESM Medium Ensemble (CESM-ME), CESM Large Ensemble (CESM-LE) and CESM with fixed aerosols Medium Ensemble (CESM-LE_FixA) simulations for the period 1920-2080. We compare K-T climate types from the Medieval Climate Anomaly (MCA) (950-1250) with the Little Ice Age (LIA) (1550-1850), from present day (PD) (1971-2000) with the last millennium (LM) (850-1850), and from the future (2050-2080) with the LM in order to place anthropogenic changes in the context of changes due to natural forcings occurring during the last millennium. For CESM-LME, we focused on the simulations with all forcings, though the impacts of individual forcings (e.g., solar activities, volcanic eruptions, greenhouse gases, aerosols and land use changes) were also analyzed. We found that the climate types changed slightly between the MCA and the LIA due to weak changes in temperature and precipitation. The climate type changes in PD relative to the last millennium have been largely driven by greenhouse gas-induced warming, but anthropogenic aerosols have also played an important role on regional scales. At the end of the twenty-first century, the anthropogenic forcing has a much greater effect on climate types than the PD. Following the reduction of aerosol emissions, the impact of greenhouse gases will further promote global warming in the future. Compared to precipitation, changes in climate types are dominated by greenhouse gas-induced warming. The large shift in climate types by the end of this century suggests possible wide-spread redistribution of surface vegetation and a significant change in species distributions.

  18. Future projections of synoptic weather types over the Arabian Peninsula during the twenty-first century using an ensemble of CMIP5 models

    2016-07-28

    An assessment of future change in synoptic conditions over the Arabian Peninsula throughout the twenty-first century was performed using 20 climate models from the Coupled Model Intercomparison Project Phase 5 (CMIP5) database. We employed the mean sea level pressure (SLP) data from model output together with NCEP/NCAR reanalysis data and compared the relevant circulation types produced by the Lamb classification scheme for the base period 1975–2000. Overall, model results illustrated good agreement with the reanalysis, albeit with a tendency to underestimate cyclonic (C) and southeasterly (SE) patterns and to overestimate anticyclones and directional flows. We also investigated future projections for each circulation-type during the rainy season (December–May) using three Representative Concentration Pathways (RCPs), comprising RCP2.6, RCP4.5, and RCP8.5. Overall, two scenarios (RCP4.5 and RCP 8.5) revealed a statistically significant increase in weather types favoring above normal rainfall in the region (e.g., C and E-types). In contrast, weather types associated with lower amounts of rainfall (e.g., anticyclones) are projected to decrease in winter but increase in spring. For all scenarios, there was consistent agreement on the sign of change (i.e., positive/negative) for the most frequent patterns (e.g., C, SE, E and A-types), whereas the sign was uncertain for less recurrent types (e.g., N, NW, SE, and W). The projected changes in weather type frequencies in the region can be viewed not only as indicators of change in rainfall response but may also be used to inform impact studies pertinent to water resource planning and management, extreme weather analysis, and agricultural production.

  19. Thomas Piketty’s Book “Capital in the Twenty-First Century”, Karl Marx and the Political Economy of the Internet

    2014-05-01

    Full Text Available Thomas Piketty’s book Capital in the Twenty-First Century has resulted in a sustained political and academic debate about capitalism in the 21st century. This article discusses the relevance of the book in the context of Karl Marx’s works and the political economy of the Internet. It identifies 3 common reactions to Piketty’s book: 1 dignification; 2 denigration of the work’s integrity; 3 the denial of any parallel to Marx. I argue that all three reactions do not help the task of creating a New Left that is urgently needed in the situation of sustained capitalist crisis. Marxists will certainly view Piketty’s analysis of capitalism and political suggestions critically. I argue that they should however not dismiss them, but like Marx and Engels aim to radicalise reform suggestions. In relation to the Internet, this paper discusses especially how insights from Piketty’s book can inform the discussion of tax avoidance by transnational Internet companies such as Google, Facebook and Amazon. For establishing an alternative, non-commercial, non-capitalist Internet one can draw insights about institutional reforms and progressive capital taxation from Piketty that can be radicalised in order to ground radical-reformist Internet politics. “The daily struggle for reforms, for the amelioration of the condition of the workers within the framework of the existing social order, and for democratic institutions, offers to the social democracy the only means of engaging in the proletarian class war and working in the direction of the final goal-the conquest of political power and the suppression of wage labor. Between social reforms and revolution there exists for the social democracy an indissoluble tie. The struggle for reforms is its means; the social revolution, its aim” (Rosa Luxemburg 1899, 41.

    An assessment of future change in synoptic conditions over the Arabian Peninsula throughout the twenty-first century was performed using 20 climate models from the Coupled Model Intercomparison Project Phase 5 (CMIP5) database. We employed the mean sea level pressure (SLP) data from model output together with NCEP/NCAR reanalysis data and compared the relevant circulation types produced by the Lamb classification scheme for the base period 1975-2000. Overall, model results illustrated good agreement with the reanalysis, albeit with a tendency to underestimate cyclonic (C) and southeasterly (SE) patterns and to overestimate anticyclones and directional flows. We also investigated future projections for each circulation-type during the rainy season (December-May) using three Representative Concentration Pathways (RCPs), comprising RCP2.6, RCP4.5, and RCP8.5. Overall, two scenarios (RCP4.5 and RCP 8.5) revealed a statistically significant increase in weather types favoring above normal rainfall in the region (e.g., C and E-types). In contrast, weather types associated with lower amounts of rainfall (e.g., anticyclones) are projected to decrease in winter but increase in spring. For all scenarios, there was consistent agreement on the sign of change (i.e., positive/negative) for the most frequent patterns (e.g., C, SE, E and A-types), whereas the sign was uncertain for less recurrent types (e.g., N, NW, SE, and W). The projected changes in weather type frequencies in the region can be viewed not only as indicators of change in rainfall response but may also be used to inform impact studies pertinent to water resource planning and management, extreme weather analysis, and agricultural production.

    Full Text Available Public health professionals have been challenged to radically reform public health training to meet evolving demands of twenty-first century public health. Such a transformation requires a systems thinking approach with an interdisciplinary focus on problem solving, leadership, management and teamwork, technology and information, budgeting and finance, and communication. This article presents processes for implementing and evaluating a revised public health curriculum and outlines lessons learned from this initiative. To date, more than 200 students have participated in the initial pilot testing of this program. A rigorous process and outcome evaluation plan was developed and employed. Results from the evaluation were used to enhance the resulting curriculum. Specifically, all instructional materials were evaluated by both the students who received the materials and the faculty who presented the materials. As each successive pilot is delivered, both enrollment and faculty involvement has increased. Through this process, the value of committed faculty, the importance of engaging learners in the evaluation of an education program, and the need to implement curriculum that has been carefully evaluated and evidence-informed in nature has emerged. We credit our successful transformation of the Masters in Public Health core to the challenge provided by the Framing the Future task force, the commitment of our College of Public Health leadership, the engagement of our faculty, and the time we allowed for the process to unfold. Ultimately, we believe this transformed curriculum will result in better trained public health professionals, interdisciplinary practitioners who can see public health challenges in new and different ways.

    A regional climate model, the Weather Research and Forecasting (WRF) Model, is forced with increased atmospheric CO{sub 2} and anomalous SSTs and lateral boundary conditions derived from nine coupled atmosphere-ocean general circulation models to produce an ensemble set of nine future climate simulations for northern Africa at the end of the twenty-first century. A well validated control simulation, agreement among ensemble members, and a physical understanding of the future climate change enhance confidence in the predictions. The regional model ensembles produce consistent precipitation projections over much of northern tropical Africa. A moisture budget analysis is used to identify the circulation changes that support future precipitation anomalies. The projected midsummer drought over the Guinean Coast region is related partly to weakened monsoon flow. Since the rainfall maximum demonstrates a southward bias in the control simulation in July-August, this may be indicative of future summer drying over the Sahel. Wetter conditions in late summer over the Sahel are associated with enhanced moisture transport by the West African westerly jet, a strengthening of the jet itself, and moisture transport from the Mediterranean. Severe drought in East Africa during August and September is accompanied by a weakened Indian monsoon and Somali jet. Simulations with projected and idealized SST forcing suggest that overall SST warming in part supports this regional model ensemble agreement, although changes in SST gradients are important over West Africa in spring and fall. Simulations which isolate the role of individual climate forcings suggest that the spatial distribution of the rainfall predictions is controlled by the anomalous SST and lateral boundary conditions, while CO{sub 2} forcing within the regional model domain plays an important secondary role and generally produces wetter conditions.

  3. Why 'class' is too soft a category to capture the explosiveness of social inequality at the beginning of the twenty-first century.

    2013-03-01

    We can distinguish four positions on the continuing, or maybe even increasing, relevance of the category of class at the beginning of the twenty-first century depending on the extent to which they accord central importance to (1) the reproduction or (2) the transformation of social classes with regard to (3) the distribution of goods without bads or (4) the distribution of goods and bads. One could say that Dean Curran introduces the concept of 'risk-class' to radicalize the class distribution of risk and charts who will able to occupy areas less exposed to risk and who will have little choice but to occupy areas that are exposed to the brunt of the fact of the risk society. As he mentioned it is important to note that this social structuring of the distribution of bads will be affected not only by class, but also by other forms of social structuration of disadvantage, such as gender and race. In order to demonstrate that the distribution of bads is currently exacerbating class differences in life chances, however, Curran concentrates exclusively on phenomena of individual risks. In the process, he overlooks the problem of systemic risks in relation of the state, science, new corporate roles, management the mass media, law, mobile capital and social movements; at the same time, his conceptual frame of reference does not really thematize the interdependence between individual and systemic risks. Those who reduce the problematic of risk to that of the life chances of individuals are unable to grasp the conflicting social and political logics of risk and class conflicts. Or, to put it pointedly: 'class' is too soft a category to capture the explosiveness of social inequality in world risk society. © London School of Economics and Political Science 2013.

    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

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.

  6. 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

    Science.gov (United States)

    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

    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

So, how does the World continue to meet its food and nutrition needs?. Solutions may come from bio-technology and precision farming, however developments in these fields are not currently moving at rates that will ensure global food security over next few decades. Further, there is a need for careful consideration of possible harmful effects of bio-technology. We should not be looking back 30– 50 years from now, like we have been looking back now at many mistakes made during the green revolution. During the green revolution the focus was only on getting more yield per unit area. Little thought was put about serious damage done to our natural environments, water resources, and human health as a result of detrimental factors such as uncontrolled use of herbicides-pesticides-nutrients, drastic groundwater mining, and salinization of fertile soils due to over irrigation. Currently, there is talk of a “second green revolution” or even an “ever green revolution”, but clear ideas on what these terms actually mean are still debated and are evolving. One of the biggest issues that are not given adequate focus is the use of large quantities of water for food production. Indeed, an overwhelming proportion (60-90%) of all human water use in India goes for producing their food (Falkenmark, M., & Rockström, 2006). But such intensive water use for food production is no longer tenable due to increasing pressure for water use alternatives such as increasing urbanization

    Full Text Available Objective: To review the literature on associations between cardiovascular diseases and tobacco use, including recent trends in smoking behaviors and clinical approaches for cessation of smoking. Methods: A literature review of recent scientific findings for smoking and cardiovascular diseases and recommendations for obtaining cessation. Results: Tobacco smoking is causally related to cardiovascular disease, with nearly a half million deaths annually attributed to cigarette smoking in the United States. The human, economic, medical, and indirect costs are enormous. Secondhand smoke as inhaled from the environment also plays an important role in the genesis of cardiovascular diseases. A recent trend in the use of e-cigarettes is noted particularly among youth. For children, prevention is the best strategy. For adult smokers, behavioral treatments, self-help approaches, and pharmacologic therapies are readily available. Clinicians can have a significant impact on patients’ smoking habits. Adding to individual strategies, regulatory community and public health approaches provide the potential for eliminating the use of tobacco. Conclusion: Tobacco smoke causes cardiovascular morbidity and death. Clinicians can play a role in preventing smoking and promoting cessation.

    Pathologists' advocacy plays a central role in the establishment of continuously improving patient care quality and patient safety, and in the maintenance and progress of pathology as a profession. Pathology advocacy's primary goal is the betterment of patient safety and quality medical care; however, payment is a necessary and appropriate component to both, and has a central role in advocacy. Now is the time to become involved in pathology advocacy; the Medicare Access and Children's Health Insurance Program (CHIP) Reauthorization Act of 2015 (MACRA) and the Protecting Access to Medicare Act of 2014 (PAMA) are 2 of the most consequential pieces of legislation impacting the pathology and laboratory industry in the last 20 years. Another current issue of far-reaching impact for pathologists is balance billing, and yet many pathologists have little or no understanding of balance billing. Pathologists at all stages of their careers, and in every professional setting, need to participate. Academic pathologists have a special obligation to, if not become directly involved in advocacy, at least have a broad and current understanding of those issues, as well as the need and responsibility of pathologists to actively engage in advocacy efforts to address them, in order to teach residents the place of advocacy, and its value, as an inseparable and indispensable component of their professional responsibilities.

    In the twenty-first century, the dynamics of health and health care are changing, necessitating a commitment to revising traditional public health curricula to better meet present day challenges. This article describes how the College of Public Health at the University of South Florida utilized the Intervention Mapping framework to translate revised core competencies into an integrated, theory-driven core curriculum to meet the training needs of the twenty-first century public health scholar and practitioner. This process resulted in the development of four sequenced courses: History and Systems of Public Health and Population Assessment I delivered in the first semester and Population Assessment II and Translation to Practice delivered in the second semester. While the transformation process, moving from traditional public health core content to an integrated and innovative curriculum, is a challenging and daunting task, Intervention Mapping provides the ideal framework for guiding this process. Intervention mapping walks the curriculum developers from the broad goals and objectives to the finite details of a lesson plan. Throughout this process, critical lessons were learned, including the importance of being open to new ideologies and frameworks and the critical need to involve key-stakeholders in every step of the decision-making process to ensure the sustainability of the resulting integrated and theory-based curriculum. Ultimately, as a stronger curriculum emerged, the developers and instructors themselves were changed, fostering a stronger public health workforce from within.

    Twenty-first century health challenges have significantly altered the expanding role and functions of public health professionals. Guided by a call from the Association of Schools and Programs of Public Health's (ASPPH) and the Framing the Future: The Second 100 Years of Education for Public Health report to adopt new and innovative approaches to prepare public health leaders, the University of South Florida College of Public Health aimed to self-assess the current Masters of Public Health (MPH) core curriculum with regard to preparing students to meet twenty-first century public health challenges. This paper describes how Intervention Mapping was employed as a framework to increase readiness and mobilize the COPH community for curricular change. Intervention Mapping provides an ideal framework, allowing organizations to access capacity, specify goals, and guide the change process from curriculum development to implementation and evaluation of competency-driven programs. The steps outlined in this paper resulted in a final set of revised MPH core competencies that are interdisciplinary in nature and fulfill the emergent needs to address changing trends in both public health education and challenges in population health approaches. Ultimately, the competencies developed through this process were agreed upon by the entire College of Public Health faculty, signaling one college's readiness for change, while providing the impetus to revolutionize the delivery of public health education at the University of South Florida.

    Tobacco smoke, active or passive exposure was the major cause of preventable morbidity and mortality in the world during twentieth century and will continue to be the same in the twenty-first century also if the current trends continue. Both active and passive smoking are having significance in relation to child health. Exposure starts antenatally from placenta to the fetus and later phases through passive exposure to experimental and regular smoking and ultimately addiction and habitual smoking. Evidences are in favour of causal relationship with intrauterine growth restriction, sudden infant death syndrome, decreased pulmonary function, increased risk for respiratory tract infection, otitis media, wheeze, asthma, neurobehavioral disorders, cleft palate and triggering pathogenesis of fetal and childhood onset of adult diseases, especially pulmonary and cardio vascular diseases. All these facts stress the importance of behavioral changes in the population as well as stringent public health measures and legislation for ensuring smoke free work places, public places and households for children. M POWER- Package by WHO is a novel global initiative taking us closer to the target of achieving tobacco free environment for children in the near future.

  1. Changes in seasonal and diurnal precipitation types during summer over South Korea in the late twenty-first century (2081-2100) projected by the RegCM4.0 based on four RCP scenarios

    2018-01-01

    Changes in seasonal and diurnal precipitation types over South Korea during summer in the late twenty-first century (2081-2100) were projected under four RCP scenarios using the Regional Climate Model (RegCM4.0) with a horizontal resolution of 12.5 km. Two boundary conditions, ERA-Interim and HadGEM2-AO, were used to drive the RegCM4.0 (jointly named RG4_ERA and RG4_HG2, respectively). In general, the RegCM4.0 reproduces the spatial distribution of summer precipitation over Northeast Asia for the current climate (1989-2008) reasonably well. The RG4_HG2 shows larger dry biases over South Korea, when compared with observations, than does the RG4_ERA. These strong dry biases result from the underestimation of convective precipitation (CPR) and are particularly noticeable in late afternoons during July and August. It is related to the performance of HadGEM2-AO which simulated southwesterly winds weakly in that time. However, interestingly, the RG4_HG2 simulates similar increases in the contribution of CPR to total precipitation after mid-July, resulting in comparable performance in the reproduction of heavy precipitation. In the late twenty-first century, a significant increase (decrease) in CPR (NCPR) is generally projected over South Korea, and particularly under the RCP8.5. During June, the total precipitation is affected primarily by changes in NCPR under RCP2.6 and RCP6.0. After mid-July, increasing total precipitation is primarily caused by the distinct increases in CPR in the late afternoons; this pattern is particularly noticeable under RCP8.5, which is associated with more destabilized atmospheric conditions during July and August. Light and heavy precipitation are projected to decrease and increase, respectively, under RCP8.5.

    2009-10-01

    Surgical smoke is the gaseous by-product formed during surgical procedures. Most surgeons, operating theatre staff and administrators are unaware of its potential health risks. Surgical smoke is produced by various surgical instruments including those used in electrocautery, lasers, ultrasonic scalpels, high speed drills, burrs and saws. The potential risks include carbon monoxide toxicity to the patient undergoing a laparoscopic operation, pulmonary fibrosis induced by non-viable particles, and transmission of infectious diseases like human papilloma virus. Cytotoxicity and mutagenicity are other concerns. Minimisation of the production of surgical smoke and modification of any evacuation systems are possible solutions. In general, a surgical mask can provide more than 90% protection to exposure to surgical smoke; however, in most circumstances it cannot provide air-tight protection to the user. An at least N95 grade or equivalent respirator offers the best protection against surgical smoke, but whether such protection is necessary is currently unknown.

    Various apparatus and methods for smoke detection are disclosed. In one embodiment, a method of training a classifier for a smoke detector comprises inputting sensor data from a plurality of tests into a processor. The sensor data is processed to generate derived signal data corresponding to the test data for respective tests. The derived signal data is assigned into categories comprising at least one fire group and at least one non-fire group. Linear discriminant analysis (LDA) training is performed by the processor. The derived signal data and the assigned categories for the derived signal data are inputs to the LDA training. The output of the LDA training is stored in a computer readable medium, such as in a smoke detector that uses LDA to determine, based on the training, whether present conditions indicate the existence of a fire.

    An ionization smoke detector consisting of two electrodes defining an ionization chamber permitting entry of smoke, a radioactive source to ionize gas in the chamber and a potential difference applied across the first and second electrodes to cause an ion current to flow is described. The current is affected by entry of smoke. An auxiliary electrode is positioned in the ionization chamber between the first and second electrodes, and it is arranged to maintain or create a potential difference between the first electrode and the auxiliary electrode. The auxiliary electrode may be used for testing or for adjustment of sensitivity. A collector electrode divides the chamber into two regions with the auxiliary electrode in the outer sensing region.

    This describes a smoke detector comprising a self-luminous light source and a photosensitive device which is so arranged that the light source is changed by the presence of smoke in a detecting region. A gaseous tritium light source is used. This consists of a borosilicate glass bulb with an internal phosphor coating, filled with tritium gas. The tritium emits low energy beta particles which cause the phosphor to glow. This is a reliable light source which needs no external power source. The photosensitive device may be a phototransistor and may drive a warning device through a directly coupled transistor amplifier. (U.K.)

    2015-01-01

    People with independent (vs. interdependent) social orientation place greater priority on personal success, autonomy, and novel experiences over maintaining ties to their communities of origin. Accordingly, an independent orientation should be linked to a motivational proclivity to move to places that offer economic opportunities, freedom, and diversity. Such places are cities that can be called "cosmopolitan." In support of this hypothesis, Study 1 found that independently oriented young adults showed a preference to move to cosmopolitan rather than noncosmopolitan cities. Study 2 used a priming manipulation and demonstrated a causal impact of independence on residential preferences for cosmopolitan cities. Study 3 established ecological validity by showing that students who actually moved to a cosmopolitan city were more independent than those who either moved to a noncosmopolitan city or never moved. Taken together, the findings illuminate the role of cosmopolitan settlement in the contemporary cultural change toward independence and have implications for urban development and economic growth.

    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. © London School of Economics and Political Science 2014.

    Alzheimer's drugs are failing at a rate of 99.6%, and success rate for drugs designed to help patients with this form of dementia is 47 times less than for drugs designed to help patients with cancers ( www.scientificamerican.com/article/why-alzheimer-s-drugs-keep-failing/2014 ). How can it be so difficult to produce a valuable drug for Alzheimer's disease? Each human has a unique genetic and epigenetic makeup, thus endowing individuals with a highly unique complement of genes, polymorphisms, mutations, RNAs, proteins, lipids, and complex sugars, resulting in distinct genome, proteome, metabolome, and also microbiome identity. This editorial is taking into account the uniqueness of each individual and surrounding environment, and stresses the point that a more accurate definition of a "common" disorder could be simply the amalgamation of a myriad of "rare" diseases. These rare diseases are being grouped together because they share a rather constant complement of common features and, indeed, generally respond to empirically developed treatments, leading to a positive outcome consistently. We make the case that it is highly unlikely that such treatments, despite their statistical success measured with large cohorts using standardized clinical research, will be effective on all patients until we increase the depth and fidelity of our understanding of the individual "rare" diseases that are grouped together in the "buckets" of common illnesses.

  15. American marriage in the early twenty-first century.

    Science.gov (United States)

    Cherlin, Andrew J

    2005-01-01

    During the past century the U.S. family system has seen vast changes--in marriage and divorce rates, cohabitation, childbearing, sexual behavior, and women's work outside the home. Andrew Cherlin reviews these historic changes, noting that marriage remains the most common living arrangement for raising children, but that children, especially poor and minority children, are increasingly likely to grow up in single-parent families and to experience family instability. Cherlin describes the economic and cultural forces that have transformed family life. Job market changes have drawn married women into the work force and deprived less-educated men of the blue-collar jobs by which they traditionally supported their families. And effective contraception and legalized abortion have eroded the norm of marriage before childbearing. Cherlin notes that sentiment in favor of marriage appears to be stronger in the United States than in other developed countries. The share of U.S. adults who are likely to marry is higher, but so is the share likely to divorce. U.S. children are also more likely to live in single-parent families at some time in their childhood. Although nearly all Americans, whether poor or well-to-do, hold to marriage as an ideal, today marriage is increasingly optional. To a greater extent than ever before, individuals can choose whether to form a family on their own, in a cohabiting relationship, or in a marriage. Given U.S. patterns of swift transitions into and out of marriage and high rates of single parenthood, American policymakers eager to promote marriage are unlikely to be able to raise U.S. family stability to levels typical of other developed countries. Consequently, a family policy that relies too heavily on marriage will not help the many children destined to live in single-parent and cohabiting families--many of them poor--during their formative years. Assistance must be directed to needy families, regardless of their household structure. Policymakers must craft a careful balance of marriage-based and marriage-neutral programs to provide adequate support to American children.

  18. 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.

  20. Water and Food in the Twenty-First Century

    Science.gov (United States)

    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.

    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.

  20. Drone Warfare: Twenty-First Century Empire and Communications

    Directory of Open Access Journals (Sweden)

    Kevin Howley

    2017-02-01

    Full Text Available This paper, part of a larger project that examines drones from a social-construction of technology perspective, considers drone warfare in light of Harold Innis’s seminal work on empire and communication. Leveraging leading-edge aeronautics with advanced optics, data processing, and networked communication, drones represent an archetypal “space-biased” technology. Indeed, by allowing remote operators and others to monitor, select, and strike targets from half a world away, and in real-time, these weapon systems epitomize the “pernicious neglect of time” Innis sought to identify and remedy in his later writing. With Innis’s time-space dialectic as a starting point, then, the paper considers drones in light of a longstanding paradox of American culture: the impulse to collapse the geographical distance between the United States and other parts of the globe, while simultaneously magnifying the cultural difference between Americans and other peoples and societies. In the midst of the worldwide proliferation of drones, this quintessentially sublime technology embodies this (disconnect in important, profound, and ominous ways.

  1. Clinical Skills Assessment in the Twenty-First Century.

    Science.gov (United States)

    Elder, Andrew

    2018-05-01

    Clinical skills remain fundamental to the practice of medicine and form a core component of the professional identity of the physician. However, evidence exists to suggest that the practice of some clinical skills is declining, particularly in the United States. A decline in practice of any skill can lead to a decline in its teaching and assessment, with further decline in practice as a result. Consequently, assessment not only drives learning of clinical skills, but their practice. This article summarizes contemporary approaches to clinical skills assessment that, if more widely adopted, could support the maintenance and reinvigoration of bedside clinical skills.

  2. A New Moon for the Twenty-First Century

    Science.gov (United States)

    Taylor, G. J.

    2000-08-01

    Thirty years of lunar sample studies supplemented by spotty remote sensing and geophysical data gave us the broad outline of the nature and geologic history of the Moon. Many cherished beliefs are now being questioned on the basis of global data returned by two bargain-basement missions sent to the Moon in the 1990s, Clementine and Lunar Prospector. These data are being integrated with new and old lunar sample data, to give us new, though still controversial, ideas about the nature of the Moon. Two articles in a special section of the Journal of Geophysical Research (Planets) illustrate the point. Brad Jolliff and his colleagues at Washington University in St. Louis, Jeff Gillis, Larry Haskin, Randy Korotev, and Mark Wieczorek (now at the Massachusetts Institute of Technology) divide the Moon's crust into distinct geochemical provinces quite different from the traditional highlands (or terra) and maria. In a separate paper, Randy Korotev presents a detailed analysis of a common rock type among the samples returned by the Apollo missions. This rock type, nicknamed enigmatically "LKFM," was thought by many of us to represent the composition of the lower crust everywhere on the Moon. Korotev argues that it is confined to only one of Jolliff's provinces. If correct, this changes our estimates of the composition of the lunar crust, hence of the entire Moon. Although other lunar scientists will scrutinize these new views of the Moon, it is clear that some long-held ideas about the Moon might be modified significantly, if not tossed out completely.

    Hoffman, H; Vu, D

    1997-12-01

    Virtual reality (VR) is gaining recognition for its enormous educational potential. While not yet in the mainstream of academic medical training, many prototype and first-generation VR applications are emerging, with target audiences ranging from first- and second-year medical students to residents in advanced clinical training. Visualization tools that take advantage of VR technologies are being designed to provide engaging and intuitive environments for learning visually and spatially complex topics such as human anatomy, biochemistry, and molecular biology. These applications present dynamic, three-dimensional views of structures and their spatial relationships, enabling users to move beyond "real-world" experiences by interacting with or altering virtual objects in ways that would otherwise be difficult or impossible. VR-based procedural and surgical simulations, often compared with flight simulators in aviation, hold significant promise for revolutionizing medical training. Already a wide range of simulations, representing diverse content areas and utilizing a variety of implementation strategies, are either under development or in their early implementation stages. These new systems promise to make broad-based training experiences available for students at all levels, without the risks and ethical concerns typically associated with using animal and human subjects. Medical students could acquire proficiency and gain confidence in the ability to perform a wide variety of techniques long before they need to use them clinically. Surgical residents could rehearse and refine operative procedures, using an unlimited pool of virtual patients manifesting a wide range of anatomic variations, traumatic wounds, and disease states. Those simulated encounters, in combination with existing opportunities to work with real patients, could increase the depth and breadth of learners' exposure to medical problems, ensure uniformity of training experiences, and enhance the acquisition of clinical skills.

  5. Cyber Attacks and Terrorism: A Twenty-First Century Conundrum.

    Albahar, Marwan

    2017-01-05

    In the recent years, an alarming rise in the incidence of cyber attacks has made cyber security a major concern for nations across the globe. Given the current volatile socio-political environment and the massive increase in the incidence of terrorism, it is imperative that government agencies rapidly realize the possibility of cyber space exploitation by terrorist organizations and state players to disrupt the normal way of life. The threat level of cyber terrorism has never been as high as it is today, and this has created a lot of insecurity and fear. This study has focused on different aspects of cyber attacks and explored the reasons behind their increasing popularity among the terrorist organizations and state players. This study proposes an empirical model that can be used to estimate the risk levels associated with different types of cyber attacks and thereby provide a road map to conceptualize and formulate highly effective counter measures and cyber security policies.

    1996-01-01

    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.

    1990-01-01

    Modern synchrotrons and storage rings are based upon the electrical technology of the 1900s boosted by the microwave radar techniques of World War II. This method of acceleration now seems to be approaching its practical limit. It is high time that we seek a new physical acceleration mechanism to provide the higher energies and luminosities needed to continue particle physics beyond the machines now on the stocks. Twenty years is a short time in which to invent, develop, and construct such a device. Without it, high-energy physics may well come to an end. Particle physicists and astrophysicists are invited to join accelerator specialists in the hunt for this new principle. This report analyses the present limitations of colliders and explores some of the directions in which one might look to find a new principle. Chapters cover proton colliders, electron-positron colliders, linear colliders, and two-beam accelerators; transverse fields, wake-field and beat-wave accelerators, ferroelectric crystals, and acceleration in astrophysics.

    Global nitrogen fixation contributes 413 Tg of reactive nitrogen (Nr) to terrestrial and marine ecosystems annually of which anthropogenic activities are responsible for half, 210 Tg N. The majority of the transformations of anthropogenic Nr are on land (240 Tg N yr(-1)) within soils and vegetation where reduced Nr contributes most of the input through the use of fertilizer nitrogen in agriculture. Leakages from the use of fertilizer Nr contribute to nitrate (NO3(-)) in drainage waters from agricultural land and emissions of trace Nr compounds to the atmosphere. Emissions, mainly of ammonia (NH3) from land together with combustion related emissions of nitrogen oxides (NOx), contribute 100 Tg N yr(-1) to the atmosphere, which are transported between countries and processed within the atmosphere, generating secondary pollutants, including ozone and other photochemical oxidants and aerosols, especially ammonium nitrate (NH4NO3) and ammonium sulfate (NH4)2SO4. Leaching and riverine transport of NO3 contribute 40-70 Tg N yr(-1) to coastal waters and the open ocean, which together with the 30 Tg input to oceans from atmospheric deposition combine with marine biological nitrogen fixation (140 Tg N yr(-1)) to double the ocean processing of Nr. Some of the marine Nr is buried in sediments, the remainder being denitrified back to the atmosphere as N2 or N2O. The marine processing is of a similar magnitude to that in terrestrial soils and vegetation, but has a larger fraction of natural origin. The lifetime of Nr in the atmosphere, with the exception of N2O, is only a few weeks, while in terrestrial ecosystems, with the exception of peatlands (where it can be 10(2)-10(3) years), the lifetime is a few decades. In the ocean, the lifetime of Nr is less well known but seems to be longer than in terrestrial ecosystems and may represent an important long-term source of N2O that will respond very slowly to control measures on the sources of Nr from which it is produced.

    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.

  14. Marketing of science in the twenty-first century

    Trivelpiece, A.

    1987-01-01

    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

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.

    2006-01-01

    Land is necessary for human flourishing, and its use remains a compelling concern for every society, even those wherein industrialization has sharply diminished people's awareness of land. Here, we consider land's influence on political thinking, particularly thinking about democratic governance, and ask if this influence might be made more beneficial by the application of lessons drawn from ecological research. We identify five such lessons and apply them in six ways to the institution of private-property rights in nature--the main legal institution that allocates and perpetuates power over land--and to modern assumptions about liberal individualism and rights to health. We conclude that people can live well on land, promoting both human and land health, only in governmental forms engaging more citizens more deliberatively than now typical even in democracies. Implications for political institutions and human welfare are discussed under conditions of globalizing interdependence.

    2001-01-01

    A relentless decrease in the size of silicon-based microelectronics devices is posing problems. The most important among these are limitations imposed by quantum-size effects and instabilities introduced by the effects of thermal fluctuations. These inherent envisaged problems of present-day systems have prompted scientists to look for alternative options. Advancement in the understanding of natural systems such as photosynthetic apparatuses and genetic engineering has enabled attention to be focused on the use of biomolecules. Biomolecules have the advantages of functionality and specificity. The invention of scanning tunneling microscopy and atomic force microscopy has opened up the possibility of addressing and manipulating individual atoms and molecules. Realization of the power of self-assembly principles has opened a novel approach for designing and assembling molecular structures with desired intricate architecture. The utility of molecules such as DNA as a three-dimensional, high-density memory element and its capability for molecular computing have been fully recognized but not yet realized. More time and effort are necessary before devices that can transcend existing ones will become easily available. An overview of the current trends that are envisaged to give rich dividends in the next millennium are discussed.

  1. Talent management for the twenty-first century.

    Science.gov (United States)

    Cappelli, Peter

    2008-03-01

    Most firms have no formal programs for anticipating and fulfilling talent needs, relying on an increasingly expensive pool of outside candidates that has been shrinking since it was created from the white-collar layoffs of the 1980s. But the advice these companies are getting to solve the problem--institute large-scale internal development programs--is equally ineffective. Internal development was the norm back in the 1950s, and every management-development practice that seems novel today was routine in those years--from executive coaching to 360-degree feedback to job rotation to high-potential programs. However, the stable business environment and captive talent pipelines in which such practices were born no longer exist. It's time for a fundamentally new approach to talent management. Fortunately, companies already have such a model, one that has been well honed over decades to anticipate and meet demand in uncertain environments: supply chain management. Cappelli, a professor at the Wharton School, focuses on four practices in particular. First, companies should balance make-versus-buy decisions by using internal development programs to produce most--but not all--of the needed talent, filling in with outside hiring. Second, firms can reduce the risks in forecasting the demand for talent by sending smaller batches of candidates through more modularized training systems in much the same way manufacturers now employ components in just-in-time production lines. Third, companies can improve their returns on investment in development efforts by adopting novel cost-sharing programs. Fourth, they should seek to protect their investments by generating internal opportunities to encourage newly trained managers to stick with the firm. Taken together, these principles form the foundation for a new paradigm in talent management: a talent-on-demand system.

    To determine the frequency of smoking on The Simpsons television show, and the relationship with the sex and age groups of characters shown smoking, and with positive, negative and neutral connotations associated with instances of smoking. Content analysis (performed from January to October 2008) of instances of smoking that appeared in the first 18 seasons of The Simpsons television show, which aired from 1989 to 2007. Frequency, impact (positive, negative, neutral) of instances of smoking; and frequency associated with age (child or adolescent versus adult characters), sex and types of characters on the show. There were 795 instances of smoking in the 400 episodes observed. Most (498; 63%) involved male characters. Only 8% of instances of smoking (63) involved child or adolescent characters. Just over a third of instances of smoking (275; 35%) reflected smoking in a negative way, compared with the majority, which reflected smoking in a neutral way (504; 63%) and the minority, which reflected smoking in a positive way (16; 2%). Child and adolescent characters were much more likely to be involved in instances of smoking reflected in a negative way compared with adult characters (odds ratio, 44.93; 95% CI, 16.15-172.18). There are a large number of instances of smoking in The Simpsons television show. Child and adolescent characters are much more likely to be portrayed in instances of smoking reflected in a negative way than adult characters. Viewing The Simpsons characters smoking may prompt children to consider smoking at an early age.

    To investigate the associations of parental smoking and secondhand smoke (SHS) exposure at home with smoking initiation among young children in Hong Kong. A prospective school-based survey of Hong Kong primary 2-4 students was conducted at baseline in 2006 and followed up in 2008. Self-administered anonymous questionnaires were used to collect information about smoking, SHS exposure at home, parental smoking, and sociodemographic characteristics. Cross-sectional and prospective associations of SHS exposure at home and parental smoking with student smoking were analyzed using logistic regression adjusting for potential confounders. Cross-sectional association between parental smoking and ever smoking was significant with adjustment of sociodemographic characteristics but became insignificant after adjusting for home SHS exposure. Home SHS exposure mediated the association between parental smoking and students smoking (p = .03). Prospectively, parental smoking was not associated with smoking initiation after adjusting for home SHS exposure. Each day increase in home SHS exposure significantly predicted 16% excess risk of smoking initiation after adjusting for parental smoking. The prospective effect of parental smoking on smoking initiation was significantly mediated by baseline home SHS exposure (p smoking initiation of young Chinese children in Hong Kong independent of parental smoking status. On the other hand, the effect of parental smoking on smoking initiation was mediated through SHS exposure at home. To prevent children from smoking as well as the harm of SHS exposure, parents and other family members should quit smoking or at least reduce smoking at home.

  2. Smoking in the movies increases adolescent smoking: a review.

    2005-12-01

    Despite voluntary restrictions prohibiting direct and indirect cigarette marketing to youth and paid product placement, tobacco use remains prevalent in movies. This article presents a systematic review of the evidence on the nature and effect of smoking in the movies on adolescents (and others). We performed a comprehensive literature review. We identified 40 studies. Smoking in the movies decreased from 1950 to approximately 1990 and then increased rapidly. In 2002, smoking in movies was as common as it was in 1950. Movies rarely depict the negative health outcomes associated with smoking and contribute to increased perceptions of smoking prevalence and the benefits of smoking. Movie smoking is presented as adult behavior. Exposure to movie smoking makes viewers' attitudes and beliefs about smoking and smokers more favorable and has a dose-response relationship with adolescent smoking behavior. Parental restrictions on R-rated movies significantly reduces youth exposure to movie smoking and subsequent smoking uptake. Beginning in 2002, the total amount of smoking in movies was greater in youth-rated (G/PG/PG-13) films than adult-rated (R) films, significantly increasing adolescent exposure to movie smoking. Viewing antismoking advertisements before viewing movie smoking seems to blunt the stimulating effects of movie smoking on adolescent smoking. Strong empirical evidence indicates that smoking in movies increases adolescent smoking initiation. Amending the movie-rating system to rate movies containing smoking as "R" should reduce adolescent exposure to smoking and subsequent smoking.

    2010-08-01

    After the invention of the cigarette 1881 the health consequences of active smoking were fully known only in 1964. Since 1986 research findings allow increasingly stronger conclusions about the impact of passive smoking on health, especially for lung cancer, cardiovascular and respiratory disease in adults and children and the sudden infant death syndrome. On the basis of current consumption patterns, approximately 450 million adults will be killed by smoking between 2000 and 2050. At least half of these adults will die between age 30 and 69. Cancer and total deaths due to smoking have fallen so far only in men in high-income countries but will rise globally unless current smokers stop smoking before or during middle age. Higher taxes, regulations on smoking, including 100 % smoke free indoor spaces, and information for consumers could avoid smoking-associated deaths. Irland was 2004 the first country worldwide introducing smoke free bars and restaurants with positive effects on compliance, health of employees and business. In the first year after the introduction these policies have resulted in a 10 - 20 % reduction of acute coronary events. In Switzerland smoke free regulations have been accepted by popular vote first in the canton of Ticino in 2006 and since then in 15 more cantons. The smoking rate dropped from 33 to 27 % since 2001.

  4. Worldwide effort against smoking.

    Science.gov (United States)

    1986-07-01

    The 39th World Health Assembly, which met in May 1986, recognized the escalating health problem of smoking-related diseases and affirmed that tobacco smoking and its use in other forms are incompatible with the attainment of "Health for All by the Year 2000." If properly implemented, antismoking campaigns can decrease the prevalence of smoking. Nations as a whole must work toward changing smoking habits, and governments must support these efforts by officially stating their stand against smoking. Over 60 countries have introduced legislation affecting smoking. The variety of policies range from adopting a health education program designed to increase peoples' awareness of its dangers to increasing taxes to deter smoking by increasing tobacco prices. Each country must adopt an antismoking campaign which works most effectively within the cultural parameters of the society. Other smoking policies include: printed warnings on cigarette packages; health messages via radio, television, mobile teams, pamphlets, health workers, clinic walls, and newspapers; prohibition of smoking in public areas and transportation; prohibition of all advertisement of cigarettes and tobacco; and the establishment of upper limits of tar and nicotine content in cigarettes. The tobacco industry spends about $2000 million annually on worldwide advertising. According to the World Health Organization (WHO), controlling this overabundance of tobacco advertisements is a major priority in preventing the spread of smoking. Cigarette and tobacco advertising can be controlled to varying degrees, e.g., over a dozen countries have enacted a total ban on advertising on television or radio, a mandatory health warning must accompany advertisements in other countries, and tobacco companies often are prohibited from sponsoring sports events. Imposing a substantial tax on cigarettes is one of the most effective means to deter smoking. However, raising taxes and banning advertisements is not enough because

  5. Smoking and adolescent health

    Directory of Open Access Journals (Sweden)

    Sang-hee Park

    2011-10-01

    Full Text Available With the Westernization and opening of our society, adolescents’ smoking is increasing and being popularized. Many adolescents start smoking at an early age out of curiosity and venturesomeness, and earlier start of smoking makes it more difficult to quit smoking. Adolescents’ habitual smoking not only becomes a gateway to all kinds of substance abuse but also causes various health problems including upper respiratory infection, immature lung development, reduced maximum vital capacity, and lung cancer. Therefore, it is quite important to prevent adolescents from smoking. The lowering of adolescents’ smoking rate cannot be achieved only through social restrictions such as stereotyped education on the harms of smoking and ID checking. In order to lower adolescents’ smoking rate substantially, each area of society should develop standardized programs and make related efforts. As adolescents’ smoking is highly influenced by home environment or school life, it is necessary to make efforts in effective education and social reinforcement in school, to establish related norms, and to execute preventive education using peer groups. When these efforts are spread throughout society in cooperation with homes and communities, they will be helpful to protect adolescents’ health and improve their quality of life.

    Secondhand smoke, which is also referred to as environmental tobacco smoke and passive smoke, is a known human carcinogen. Secondhand smoke also causes disease and premature death in nonsmoking adults and children. We summarize studies of secondhand smoke in public places before and after smoking bans, as well as studies of cardiovascular and respiratory disease before and after such bans. To protect the public from the harmful effects of secondhand smoke, smoke-free legislation is an effective public health measure. Smoking bans in public places, which have been implemented in many jurisdictions across the U.S. and in other countries, have the potential to influence social norms and reduce smoking behavior. Through legislative smoking bans for reducing secondhand smoke exposure and smoking prevalence, opportunities exist to protect the health of Georgians and other Americans and to reduce health care costs. These opportunities include increasing the comprehensiveness of smoking bans in public places and ensuring adequate funding to quit line services.

    Characterization of smoke, factors influencing smoke production and experimental methods for measuring smoke production are discussed in this literature review. Recent test-based correlation models are also discussed. Despite the large number of laboratories using different fire testing methods, published smoke data have been scarce. Most technical literature on smoke production from building materials is about experimental results in small scale tests. Compilations from cone calorimeter tests have been published for a few materials, e.g. upholstered furniture materials and some building products. Mass optical density data and compilations of gravimetric soot data are available for various materials as well as a number of smoke obscuration values. For a given material often a wide range of values of smoke output can be found in the literature and care should be exercised in applying the appropriate value in each case. In laboratory experiments, the production of smoke and its optical properties are often measured simultaneously with other fire properties as heat release and flame spread. The measurements are usually dynamic in full scale, i.e. they are performed in a flow-through system. In small scale they may be either dynamic, as in the cone calorimeter, or static, i.e. the smoke is accumulated in a closed box. Small-scale tests are necessary as practical tools. Full-scale tests are generally considered to be more reliable and are needed to validitate the small-scale tests

    1996-10-01

    Cigarette smoking is a major preventable cause of morbidity and mortality worldwide. Most adult smokers start smoking regularly some time before 18 years of age. The aim of this study was to determine the age at which children begin cigarette smoking, to study the environmental factors that influence children to smoke, and to understand the reasons why children smoke. The results of this study may help lead to the development of more effective smoking prevention programs. We carried out a cross-sectional survey of all students in grades 6 to 11 (ages: 11 to 17 years) in two high schools in the Jerusalem area, using an anonymous self-completion questionnaire. The students were asked questions regarding the age at which they began smoking, initiation, their smoking habits, their reasons for smoking, and their views on children who smoke. In addition, they were asked about the smoking status of their parents, siblings, and friends. Finally they were asked about the health hazards of smoking. Of the 847 students who answered the questionnaire, 35% stated that they had smoked at least once and 14% stated that they were currently smoking. The percentage of students who were currently smoking increased gradually with age to 36%. There was a sharp increase in experimental smoking after seventh grade (ages 12 to 13 years). Having a friend who smoked substantially increased the likelihood of smoking, whereas parental smoking or having a sibling who smoked did not increase the likelihood of smoking. The most common reason for starting to smoke was "to try something new" (55%). There was a significant difference between the views of students with different smoking statuses regarding children who smoke: nonsmoking children associated more negative characteristics to smoking. All of the children studied were well aware of the health hazards of cigarette smoking. Smoking is highly prevalent among schoolchildren in Jerusalem. The increase in the rate of smoking at the age of 12

    Smoking kills over half a million women each year and is the most important preventable cause of female premature death in several developed countries. However, in many countries, cigarette smoking still tends to be regarded as a mainly male problem. This paper explores the reasons why more attention needs to be paid to issues around smoking and women, even in countries which currently have low levels of female cigarette smoking. The article includes an overview of current patterns and trends of smoking among women, and the factors which influence smoking uptake and cessation in women compared to men. The experience of countries with the longest history of widespread female smoking is used to identify some of the key challenges facing developed and developing countries. Tobacco companies have identified women as a key target group, therefore particular attention is given to the ways in which they have attempted to reach women through advertising and other marketing strategies. It is concluded that in order to halt and ultimately reverse the tobacco epidemic among women, tobacco control policies need to encompass both gender-specific and gender-sensitive approaches. Examples are given of the types of action that are needed in relation to research, public policy and legislation, and education.

    2005-05-01

    This study examined the smoking habits and attitudes towards smoking among Estonian physicians. Cross-sectional data for 2668 physicians were gathered by a self-administered postal survey. The current smoking prevalence was 24.9% for male physicians and 10.8% for female physicians. The percentages of ex-smokers were 32.9 and 16.8%, respectively. Smoking prevalence among physicians was below the levels reported for the highest educational bracket of the total population in Estonia. Non-smoking physicians had more unfavourable views towards smoking than those who smoked. The majority of physicians were aware of the association between smoking and various diseases, with significant differences between smokers and non-smokers. Non-smoking physicians were more active in asking patients about smoking habits than those who smoked. Most Estonian physicians, especially those who smoked, failed to perceive themselves as positive role models. This study found a lower prevalence of smoking among physicians compared with the general population, and demonstrated the impact of personal smoking on physicians' attitudes towards smoking. The results provide an important challenge to medical education in Estonia.

    Full Text Available There is little debate as to the harmful effects of cigarette smoking on health. Most health workers advise their patients to cease the practice. The impact of the advice is however diluted if it is seen to be ignored by the professionals themselves. As nurses play an increasing role in all levels of health care a survey was undertaken to investigate the smoking habits of two groups of nurses - those operating within the community and those working in institutions.

    The aim of this study was to examine whether smoking in movies can predict established smoking in adolescence. A longitudinal study was conducted over a period of 13 months with 4112 German students. Adolescents' exposure to smoking in movies was assessed by asking each student to indicate which film he or she had seen from a unique list of 50 movies, which was randomly selected for each individual survey from a sample of 398 popular contemporary movies. We calculated exposure to movie smoking for each respondent by summing the number of smoking occurrences for each movie that the respondent reported seeing. At follow-up, a total of 272 young people had smoked more than 100 cigarettes during their lifetime. While 2.1% of the young people with the lowest exposure to movie smoking initiated established smoking, 13.4% of the group with the highest exposure to movie smoking initiated established smoking. The adjusted relative risk of initiation of established smoking was 2.05 times higher in the group with the highest movie smoking exposure compared to the group with the lowest exposure (95% confidence interval: 1.25-3.35). Our data indicate that smoking in movies can be regarded as an independent risk factor for the initiation of established smoking in adolescence. © Georg Thieme Verlag KG Stuttgart · New York.

    Acupuncture is promoted as a treatment for smoking cessation, and is believed to reduce withdrawal symptoms. The objective of this review is to determine the effectiveness of acupuncture in smoking cessation in comparison with: a) sham acupuncture b) other interventions c) no intervention. We searched the Cochrane Tobacco Addiction Group trials register, Medline, PsycLit, Dissertation Abstracts, Health Planning and Administration, Social SciSearch, Smoking & Health, Embase, Biological Abstracts and DRUG. Randomised trials comparing a form of acupuncture with either sham acupuncture, another intervention or no intervention for smoking cessation. We extracted data in duplicate on the type of subjects, the nature of the acupuncture and control procedures, the outcome measures, method of randomisation, and completeness of follow-up. We assessed abstinence from smoking at the earliest time-point (before 6 weeks), at six months and at one year follow-up in patients smoking at baseline. We used the most rigorous definition of abstinence for each trial, and biochemically validated rates if available. Those lost to follow-up were counted as continuing to smoke. Where appropriate, we performed meta-analysis using a fixed effects model. We identified 18 publications involving 20 comparisons. Acupuncture was not superior to sham acupuncture in smoking cessation at any time point. The odds ratio (OR) for early outcomes was 1.22 (95% confidence interval 0.99 to 1.49); the OR after 6 months was 1.38 (95% confidence interval 0.90 to 2.11) and after 12 months 1.02 (95% confidence interval 0.72 to 1.43). Similarly, when acupuncture was compared with other anti-smoking interventions, there were no differences in outcome at any time point. Acupuncture appeared to be superior to no intervention in the early results, but this difference was not sustained. The results with different acupuncture techniques do not show any one particular method (i.e. auricular acupuncture or non

    Hypnotherapy is widely promoted as a method for aiding smoking cessation. It is proposed to act on underlying impulses to weaken the desire to smoke or strengthen the will to stop. To evaluate the efficacy of hypnotherapy for smoking cessation. We searched the Cochrane Tobacco Addiction Group Specialized Register and the databases MEDLINE, EMBASE, AMED, SCI, SSCI using the terms smoking cessation and hypnotherapy or hypnosis. Date of most recent searches July 2010. There were no language restrictions. We considered randomized controlled trials of hypnotherapy which reported smoking cessation rates at least six months after the beginning of treatment. Three authors independently extracted data on participant characteristics, the type and duration of the hypnotherapy, the nature of the control group, smoking status, method of randomization, and completeness of follow up. They also independently assessed the quality of the included studies.The main outcome measure was abstinence from smoking after at least six months follow up. We used the most rigorous definition of abstinence in each trial, and biochemically validated rates where available. Those lost to follow up were considered to be smoking. We summarised effects as risk ratios (RR). Where possible, we performed meta-analysis using a fixed-effect model. We also noted any adverse events reported. Eleven studies compared hypnotherapy with 18 different control interventions. There was significant heterogeneity between the results of the individual studies, with conflicting results for the effectiveness of hypnotherapy compared to no treatment, or to advice, or psychological treatment. We did not attempt to calculate pooled risk ratios for the overall effect of hypnotherapy. There was no evidence of a greater effect of hypnotherapy when compared to rapid smoking or psychological treatment. Direct comparisons of hypnotherapy with cessation treatments considered to be effective had confidence intervals that were too

  20. Smoking habits and smoking cessation among North Carolina nurses.

    1989-01-01

    A 1987 questionnaire survey of a 1% random sample (n = 356) of registered nurses in North Carolina provided data on the smoking habits and smoking cessation. Fifty-six percent were never smokers; 19% were current smokers. Among the ever smokers, 31% had quit smoking for at least one year. Twenty-two percent of the former smokers had smoked less than 5 years and 39% less than 10 years before quitting. Anecdotal notes from never smokers suggested that their major deterrent to smoking was their own parents smoking. Concerns about the addictive smoking behavior and health effects of smoking observed in their parents as well as concerns about potential health risks to themselves deterred them from smoking. Concerns about the adverse consequences of smoking was the most influential factor influencing smoking cessation and reduction of cigarette smoking. Friends' and family's encouragement to stop smoking was the most influential external factor motivating nurses to quit or reduce cigarette consumption. Fifty-seven percent of the former smokers quit smoking after one or two attempts while 53 of the current smokers had tried to quit 3 or more times - 90% had tried at least once to quit smoking; however, only 18% of the current smokers had abstained for more than one year during any of their attempts to quit. Implications of the results include: (1) smoking cessation programs for nurses in the workplace may have considerable impact since the majority of nurses who smoke are tying to quit; (2) relapse prevention strategies need to be an integral part of such smoking cessation programs including involvement of family and friends to support the smokers in their cessation efforts.

    2010-01-01

    Background The National Cancer Institute has concluded that exposure to smoking in movies causes adolescent smoking and there are similar results for young adults. Purpose This study investigated whether exposure of young adult smokers to images of smoking in films stimulated smoking behavior. Methods 100 cigarette smokers aged 18–25 years were randomly assigned to watch a movie montage composed with or without smoking scenes and paraphernalia followed by a10-minute recess. The outcome was whether or not participants smoked during the recess. Data were collected and analyzed in 2008 and 2009. Results Smokers who watched the smoking scenes were more likely to smoke during the break (OR3.06, 95% CI=1.01, 9.29). In addition to this acute effect of exposure, smokers who had seen more smoking in movies before the day of the experiment were more likely to smoke during the break (OR 6.73; 1.00–45.25 comparing the top to bottom percentiles of exposure) were more likely to smoke during the break. Level of nicotine dependence (OR 1.71; 1.27–2.32 per point on the FTND scale), “contemplation” (OR 9.07; 1.71–47.99) and “precontemplation” (OR 7.30; 1.39–38.36) stages of change, and impulsivity (OR 1.21; 1.03–1.43), were also associated with smoking during the break. Participants who watched the montage with smoking scenes and those with a higher level of nicotine dependence were also more likely to have smoked within 30 minutes after the study. Conclusions There is a direct link between viewing smoking scenes and immediate subsequent smoking behavior. This finding suggests that individuals attempting to limit or quit smoking should be advised to refrain from or reduce their exposure to movies that contain smoking. PMID:20307802

    To examine the relation between exposure to passive parental smoke and myopia in Chinese children in Singapore. 1334 Chinese children from three schools in Singapore were recruited, all of whom were participants in the Singapore Cohort study Of the Risk factors for Myopia (SCORM). Information on whether the father or mother smoked, number of years smoked, and the number of cigarettes smoked per day during the child's lifetime were derived. These data were correlated with contemporaneously obtained data available in SCORM. The children's cycloplegic autorefraction, corneal curvature radius, and biometry measures were compared with reported parental smoking history. There were 434 fathers (33.3%) and 23 mothers (1.7%) who smoked during their child's lifetime. There were no significant trends observed between paternal smoking and refractive error or axial length. After controlling for age, sex, school, mother's education, and mother's myopia, children with mothers who had ever smoked during their lifetime had more "positive" refractions (adjusted mean -0.28 D v -1.38 D) compared with children whose mother did not smoke (p = 0.012). The study found no consistent evidence of association between parental smoking and refractive error. There was a suggestion that children whose mothers smoked cigarettes had more hyperopic refractions, but the absence of a relation with paternal smoking and the small number of mothers who smoked in this sample preclude definite conclusions about a link between passive smoking exposure and myopia.

    On January 1, 2008, the French government implemented a national ban on indoor smoking in hospitality venues. Survey results indicate the indoor ban has been successful at dramatically reducing indoor smoking; however, there are reports of an increased number of outdoor hospitality spaces (patios) where smoking can take place. This study sought to understand if the indoor ban simply moved smoking to the outdoors, and to assess levels of support for smoking restrictions in outdoor hospitality settings after the smoke-free law. Telephone interviews were conducted among 1067 adult smokers before and after the 2008 indoor ban as part of the International Tobacco Control (ITC) France Survey. Among other topics, this survey measures how the smoking ban has influenced smoking behaviour relevant to outdoor sections of hospitality venues. In addition, 414 non-smoking adults and 164 respondents who had quit smoking between waves were also asked about support for outdoor smoking restrictions. Reported smoking outdoors at cafés/pubs/bars increased from 33.6% of smokers at Wave 1 to 75.9% at Wave 2. At restaurants, smoking outdoors increased from 28.9% to 59.0%. There was also an increase in reported non-smoking for both visits to cafés/pubs/bars, and restaurants from 13.4% to 24.7%, and 30.4% to 40.8% respectively. The majority of smokers (74.5%), non-smokers (89.4%) and quitters (74.0%) support a partial or complete ban on smoking in outdoor areas of restaurants. The indoor smoking ban moved smoking to outdoor spaces; however, the ban is also associated with increased non-smoking behaviour. The majority of respondents support outdoor smoking restrictions in patio environments.

    It is known that exposure to smoking cues increases urge to smoke (UTS), but little is known about other media factors that might also increase UTS. We hypothesized that horror/thriller movies might also increase UTS by increasing negative affect. We surveyed 536 movie patrons who were smokers aged 18 years or older. Subjects had exited 26 movies, of which 12 contained smoking and two were horror films, one with and one without smoking. We used random effects regression to assess the association between exposure to movie smoking, movie horror, both and UTS, controlling for confounding factors. Median age was 26 years and 52% were female. Mean UTS was 5.9, 6.6, 6.6, and 8.7 for smokers exiting movies without smoking, with smoking, horror without smoking and horror with smoking respectively. Smoking in movies was associated with a significantly higher UTS (0.63 [95% CI 0.31–0.94]). Horror with smoking increased UTS by 2.8 points (95% C.I. 2.3, 3.5); the horror without smoking estimate was 0.88, but not statistically significant. This short report offers preliminary evidence that movie horror as one factor besides visual smoking cues that could increase UTS in a community setting. PMID:20301876

  5. Peers and adolescent smoking.

    There is a considerable body of empirical research that has identified adolescent peer relationships as a primary factor involved in adolescent cigarette smoking. Despite this large research base, many questions remain unanswered about the mechanisms by which peers affect youths' smoking behavior. Understanding these processes of influence is key to the development of prevention and intervention programs designed to address adolescent smoking as a significant public health concern. In this paper, theoretical frameworks and empirical findings are reviewed critically which inform the current state of knowledge regarding peer influences on teenage smoking. Specifically, social learning theory, primary socialization theory, social identity theory and social network theory are discussed. Empirical findings regarding peer influence and selection, as well as multiple reference points in adolescent friendships, including best friendships, romantic relationships, peer groups and social crowds, are also reviewed. Review of this work reveals the contribution that peers have in adolescents' use of tobacco, in some cases promoting use, and in other cases deterring it. This review also suggests that peer influences on smoking are more subtle than commonly thought and need to be examined more carefully, including consideration of larger social contexts, e.g. the family, neighborhood, and media. Recommendations for future investigations are made, as well as suggestions for specific methodological approaches that offer promise for advancing our knowledge of the contribution of peers on adolescent tobacco use.

  6. Radiological hazards of smoking

    2011-01-01

    A study of Polonium-210 and Lead -210 contents of tobacco has a great importance because of the increase in the incidence of lung cancer observed among smokers. The carcinogenic effect of 210 Po and 210 Pb with respect to lung cancer is an important problem in many countries with very high cigarette consumption. Naturally occurring primordial radionuclides of the uranium-radium series have long been associated with tobacco plants. The properties and distribution of trichomes on tobacco leaf surfaces suggest that they are effective collectors of small particles. It was reported that for an individual smoking two packages of cigarettes a day, the radiation dose to bronchial epithelium from 210 Po inhaled in cigarette smoking probably is at least seven times that from background sources. The effective dose of persons who smoke one or more packs per day of low quality brands is much higher than that resulting from intake with food and water. This indicates that smoke absorbed through the respiratory system is the main source and the principal pathway of 210 Po and 210 Pb intake. Cigarette smoking can be the reason for the higher incidence of cancer of all organs of the respiratory system. (author)

  7. Ion smoke detector

    This invention covers an ion smoke detector in which the capacity that the smoke will cross, in the event of an accident, is irradiated by a very low energy radioactive source. The gas in the containment is thus partially ionised. Smoke in this containment reduces the mobility of the ions, thereby increasing the impedance of the measuring chamber. A leak tight reference chamber that therefore receives no smoke is added to the measuring chamber. This chamber is filled with the same gas as that present in the measuring chamber and undergoes the same irradiation. It is of course subjected to the same conditions of temperature, atmospheric pressure and hygrometry as the measuring chamber. This makes it possible to break free from the fluctuations of the impedance of the chamber which would seem to be due to these interferences. One only radioactive source irradiates the measuring chamber and the reference chamber. The measuring chamber is in the shape of a cylinder open at one end and the reference chamber is annular and encompasses the measuring chamber. Provision is made for detecting an increase in the potential across the terminals of the measuring chamber in relation to the reference chamber, which is characteristic of the presence of smoke and other provisions separate from the former for dectecting a reduction in potential between the electrodes of the first ionisation chamber, which is characteristic of a change in the detector [fr

    Full Text Available Rheumatoid arthritis (RA is a chronic inflammatory disease caused by both genetic and environmental factors. Smoking has been implicated as one of the most important extrinsic risk factors for its development and severity. Recent developments have shed light on the pathophysiology of RA in smokers, including oxidative stress, inflammation, autoantibody formation and epigenetic changes. The association of smoking and the development of RA have been demonstrated through epidemiologic studies, as well as through in vivo and animal models of RA. With increased use of biological agents in addition to standard disease-modifying antirheumatic drugs (DMARDs, there has been interest in how smoking affects drug response in RA treatment. Recent evidence suggests the response and drug survival in people treated with anti-tumour necrosis factor (anti-TNF therapy is poorer in heavy smokers, and possible immunological mechanisms for this effect are presented in the current paper.

    Background “Social smoking” - smoking mostly or even only with others – may be an important pattern that implies smoking motivated extrinsically by social influences. Non-daily smokers (intermittent smokers; ITS) are often assumed to be social smokers, with some authors even assuming that all ITS are social smokers (SS+). We sought to identify and characterize social smokers in a sample of ITS. Methods 204 adult ITS (smoking 4–27 days/month) recorded the circumstances of smoking in their natural settings using Ecological Momentary Assessment, while also recording their circumstances in nonsmoking moments. SS+ were defined as ITS who were with others when they smoked most of their cigarettes, and who were ≥ 50% more likely to be with others when smoking than when not. Results Only 13% of ITS were SS+. Although defined solely on the basis of presence of others, SS+ showed a distinct pattern of smoking across multiple dimensions: Compared to other ITS (who were significantly less likely to smoke when with others), SS+ smoking was more associated with socializing, being with friends and acquaintances, drinking alcohol, weekends, evening or nighttime, being in other people’s homes, but not their own home. SS+ smoking was low in the morning and increased in the evening. SS+ smoked fewer days/week and were less dependent, but did not differ demographically. Conclusions Social smoking does constitute a highly distinct smoking pattern, but is not common among adult ITS. PMID:26205313

    Waterpipe tobacco smoking is a global health concern. Laboratory research has focused on individual waterpipe users while group use is common. This study examined user toxicant exposure and smoke toxicant yield associated with individual and group waterpipe smoking. Twenty-two pairs of waterpipe smokers used a waterpipe individually and as a dyad. Before and after smoking, blood was sampled and expired carbon monoxide (CO) measured; puff topography was recorded throughout. One participant from each pair was selected randomly and their plasma nicotine and expired air CO concentrations were compared when smoking alone to when smoking as part of a dyad. Recorded puff topography was used to machine-produce smoke that was analyzed for toxicant content. There was no difference in mean plasma nicotine concentration when an individual smoked as part of a dyad (mean = 14.9 ng/ml; standard error of the mean [SEM] = 3.0) compared to when smoking alone (mean = 10.0 ng/ml; SEM = 1.5). An individual smoking as part of as a dyad had, on average, lower CO (mean = 15.8 ppm; SEM = 2.0) compared to when smoking alone (mean= 21.3 ppm; SEM = 2.7). When two participants smoked as a dyad they took, on average, more puffs (mean = 109.8; SEM = 7.6) than a singleton smoker (mean = 77.7; SEM = 8.1) and a shorter interpuff interval (IPI; dyad mean = 23.8 seconds; SEM = 1.9; singleton mean = 40.8 seconds; SEM = 4.8). Higher concentrations of several toxicants were observed in dyad-produced smoke. Dyad smoking may increase smoke toxicant content, likely due to the dyad's shorter IPIs and greater puff number. More work is needed to understand if group waterpipe smoking alters the health risks of waterpipe tobacco smoking. This study is the first to measure toxicants in smoke generated from a waterpipe when used by a dyad. Relative to smoke generated by a singleton, dyad smoke had higher concentration of some toxicants. These differences may be attributed to differences in puffing behavior

    Cannabis is the most commonly smoked illicit substance in the world. It can be smoked alone in plant form (marijuana) but it is mainly smoked mixed with tobacco. The combined smoking of cannabis and tobacco is a common-place phenomenon in our society. However, its use is responsible for severe pulmonary consequences. The specific impact of smoking cannabis is difficult to assess precisely and to distinguish from the effect of tobacco. Marijuana smoke contains polycyclic aromatic hydrocarbons and carcinogens at higher concentration than tobacco smoke. Cellular, tissue, animal and human studies, and also epidemiological studies, show that marijuana smoke is a risk factor for lung cancer. Cannabis exposure doubles the risk of developing lung cancer. This should encourage clinicians to identify cannabis use and to offer patients support in quitting. Copyright © 2014 SPLF. Published by Elsevier Masson SAS. All rights reserved.

    Smoking is one of the major Public Health problems worldwide. To study the frequency of tobacco smoking among undergraduate students of a Chilean university. An opinion survey was sent by e-mail to all undergraduate students of a university, registering gender, age, study years, study area, smoking behavior, motivation (reason for smoking), intention to quit and tobacco law perception. 1,008 (57% females) out of 11,679 surveys were answered back. Prevalence of active smoking among respondents was 36%, without association with gender, age or years of study. However, students from scientific areas had a lower prevalence. Seventy seven percent of smokers manifested the intention to quit the habit or have started quitting already. Ninety six percent were acquainted with the tobacco law and by 73% agreed with it. Smoking is highly prevalent among university students. It is necessary to develop strategies for smoking cessation within universities that may prevent or reduce tobacco smoking among students.

    Passive or involuntary smoking is the inhalation of smoke which escapes directly into the air from the lit end of a burning cigarette. This unfiltered smoke contains the same toxic components of the mainstream smoke inhaled directly by the smoker, including numerous carcinogens, many in greater concentrations. It has long been known that exposure to this type of smoke leads to increased respiratory and other adverse health conditions in non-smokers, especially children. During the past five years, evidence has been accumulating that risk of lung cancer is also higher, particularly in non-smoking women whose husbands smoke. Despite uncertainties and differences in interpretation of various cancer studies, there is ample justification for public health measures now in place or proposed, such as restriction or elimination of smoking in the workplace and in public places.

    Tobacco smoking is common among various social groups. There is still high prevalence of smoking among health care professionals. The aim of the study was to assess knowledge about smoke-free law in public places in Poland among smoking and nonsmoking students of selected medical university. We surveyed 50 students of one medical university aged 23 +/- 2 years. Control group consisted with 61 students of other universities located in the same region aged 23 +/- 3 years. We developed a new survey to assess students knowledge about smoke-free regulations and their implementations in various public places. Smoking status was verified with exhaled carbon monoxide levels (COex). 57% off all surveyed students declared being familiar with smoke-free law. However, we detected a significant difference between the knowledge of medical vs. nonmedical students (76% vs. 41%, p < 0.05). The knowledge about smoke-free law in Poland among students is not sufficient, especially among nonmedical students.

    2018-07-01

    We explored the role of rejection of parental smoking in the association between parental smoking and smoking in adolescents. In 2010-11 cross-sectional survey, 61,810 Hong Kong secondary school students (mean age 14.6 years, 50.5% boys) reported their smoking (never, not susceptible; never, susceptible; ever, not current; current), paternal and maternal smoking, and whether they accepted paternal and maternal smoking (acceptance/rejection). We used multinomial logistic regression to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) of students' smoking in relation to acceptance and rejection of parental smoking, compared with no parental smoking. The OR (95% CI) of "never, susceptible", "ever, not current", and "current", compared with "never, not susceptible", in relation to acceptance of paternal smoking was 1.81 (1.67-1.96), 2.46 (2.25-2.69), and 2.79 (2.51-3.10), respectively. The corresponding ORs for rejection were 0.70 (0.64-0.76), 1.23 (1.13-1.35), and 0.47 (0.40-0.56). The OR (95% CI) of "never, susceptible", "ever, not current", and "current", compared with "never, not susceptible", in relation to acceptance of maternal smoking was 2.05 (1.80-2.33), 2.57 (2.29-2.88), and 6.33 (5.39-7.44), respectively. The corresponding ORs for rejection were 0.85 (0.69-1.05), 1.59 (1.39-1.81), and 2.14 (1.71-2.68). No overlapping was observed between the 95% CIs for acceptance and rejection of paternal or maternal smoking. While adolescent smoking was associated with parental smoking, especially in those who accepted parental smoking, the association was attenuated or reversed in those who rejected parental smoking.

    Although most agree that the association between tobacco marketing and youth smoking is causal, few studies have assessed the specificity of this association. This study aims to examine the specificity of the association between cigarette advertising and teen smoking. A cross-sectional survey of 3415 German schoolchildren aged 10-17 years was conducted using masked images of six cigarette brands and eight other commercial products in 2008. The exposure variable was a combination of contact frequency (recognition) and brand names (cued recall). Sample quartile (Q) exposure to advertisement exposure was calculated in 2009. Outcome variables were ever tried and current (monthly) smoking, and susceptibility to smoking among never smokers. The prevalence of ever smoking was 31.1% and that of current smoking was 7.4%, and 35.3% of never smokers were susceptible to smoking. Ad recognition rates ranged from 15% for a regionally advertised cigarette brand to 99% for a sweet. Lucky Strike and Marlboro were the most highly recognized cigarette brands (with ad recognition rates of 55% and 34%, respectively). After controlling for a range of established influences on smoking behaviors, the adjusted ORs for having tried smoking were 1.97 (95% CI=1.40, 2.77) for Q4 exposure to cigarette ads compared with adolescents in Q1, 2.90 (95% CI=1.48, 5.66) for current smoking, and 1.79 (95% CI=1.32, 2.43) for susceptibility to smoking among never smokers. Exposure to ads for commercial products other than cigarettes was significantly associated with smoking in crude but not multivariate models. This study underlines the specificity of the relationship between tobacco marketing and youth smoking, with exposure to cigarette ads, but not other ads, being associated with smoking behavior and intentions to smoke. This finding suggests a content-related effect of tobacco advertisements. 2010 American Journal of Preventive Medicine. Published by Elsevier Inc. All rights reserved.

  20. Is the smoking decision an 'informed choice'? Effect of smoking risk factors on smoking beliefs.

    Science.gov (United States)

    Leventhal, H; Glynn, K; Fleming, R

    1987-06-26

    The argument that people freely choose to smoke assumes that individuals at the point of initiation of smoking (often in adolescence) hold accurate beliefs about smoking. Smoking beliefs and the presence of known smoking risk factors were assessed in interviews with a sample of 895 urban young people. The respondents greatly overestimated the prevalence of adult and peer smoking, negative attitudes of their peers were greatly underestimated, a large proportion believed that they would be less likely than other people to contract a smoking-related illness if they became smokers, and there was a general lack of understanding of the adverse consequences experienced upon smoking cessation. These misperceptions were more common among youngsters who were smokers, who intended to smoke, or who had friends or family members who smoked. Because misinformation among young people is widespread and those at greatest risk for smoking are the most misinformed, the tobacco industry's argument that the decision to smoke reflects an "informed choice" is without merit.

    To explore whether parental behaviours related to smoking socialisation and parenting are associated with smoking susceptibility and current smoking in 14-15 year old students. Data were sourced from the New Zealand 2006 Year 10 In-depth Survey, a school-based survey of 3,189 students. Outcome measures were susceptibility to smoking and current smoking. Potential determinants were second-hand smoke exposure in the home, parental smoking, parental anti-smoking expectations, anti-smoking rules, pocket money, monitoring of pocket money expenditure, general rule setting and monitoring, and concern about education. Analysis used logistic regression to adjust for potential confounding factors. Exposure to second-hand smoke and lack of parental anti-smoking expectations were independently associated with smoking susceptibility and current smoking. Parental smoking was not independently associated with current smoking or susceptibility. Receiving pocket money and an absence of monitoring of expenditure were associated with smoking susceptibility and current smoking. Lack of parental rule setting was associated with smoking susceptibility. Findings were similar whether or not one or more parents were smokers. Not allowing smoking in the home, communicating non-smoking expectations to children, monitoring pocket money, and setting rules to guide behaviour are strategies which are likely to reduce risk of smoking uptake. The study provides evidence to inform the development of parent-focused interventions to reduce the risk of smoking initiation by children. © 2011 The Authors.

    Drews, M. J.

    Despite a reduction in Federal regulatory activity, research concerned with flame retardancy and smoke suppression in the private sector appears to be increasing. This trend seem related to the increased utilization of plastics for end uses which traditionally have employed metal or wood products. As a result, new markets have appeared for thermally stable and fire resistance thermoplastic materials, and this in turn has spurred research and development activity. In addition, public awareness of the dangers associated with fire has increased as a result of several highly publicized hotel and restaurant fires within the past two years. The consumers recognition of flammability characteristics as important materials property considerations has increased. The current status of fire and smoke retardant chemistry and research are summarized.

    The effects of smoke fumes on the growth of crops and on the reaction of soils in Yorkshire during the last 15 years are reported. Attention is focused on the scorching effect on vegetation caused by acid rain, and the indirect effect of these acids on plants by reducing the lime status of the soil. In cities and towns the worst offenders are domestic chimneys which contribute 150 tons of sulfur to the atmosphere every week. In less densely populated industrial districts, the bulk of the fumes are contributed by industrial chimneys and by the smouldering pit heaps of collieries. The symptoms of smoke damage on wheat are the scorching of the tip of the leaf, followed by a yellowing of the remainder of the leaf. Adequate liming greatly increases the resistance of crops to attacks by fumes. The effect of acid fumes on the soil is also discussed.

    The major objective of this project is to obtain experimental data that are directly applicable to resolving the question of whether cigarette smokers are at greater risk than nonsmokers to potential health effects of inhaled plutonium. Because cigarette smokers constitute a large fraction of the population, a synergistic effect of plutonium and cigarette smoke might influence estimates of the health risk for plutonium and other transuranics released to the environment

    2004-03-01

    This paper describes secondhand smoke (SHS) litigation over the past quarter century where non-smoking litigants have prevailed and attempts to decipher trends in the law that may impact the course of future cases. Since the early 1980s, the author has sought and examined legal cases in which SHS exposure is an important factor. Law library searches using the official reporter system (for example, Shimp v. New Jersey Bell Telephone Co., 368 A.2d 408) have more recently been combined with computerised online searches using LexisNexis and Westlaw. The author has learned of other cases through personal correspondence and from articles in newspapers. Over 420 cases involving exposure to SHS were identified. Each case was reviewed and summarised. Since 1976, the year of the first reported SHS lawsuit, this type of litigation has increased both in number and in scope with increasing success. While it is common for initial cases to lose in a new area where the law eventually evolves, litigants and their lawyers who later bring similar cases can learn from those previous, unsuccessful cases. It is now apparent that the judicial branch has begun to recognise the need to protect the public-especially some of the most vulnerable members of our society-from the serious threat to their health that is exposure to SHS. Successful cases brought on behalf of individuals exposed to SHS produce an additional benefit for the public health by both paving the way for other non-smoking litigants to succeed in their cases and persuading business owners and others voluntarily to make their facilities 100% smoke-free.

    We assessed the relation between PE and smoking in 1,563 cases (1,068 men and 495 women) who underwent CT scaring for suspicion of respiratory disease on chest radiograph or some respiratory complaints. PE was diagnosed by the existence of low attenuation areas in CT scan and not by pulmonary function tests. CT was performed with 10 mm collimation in a standard algorithm. There were 2 subtypes of pulmonary emphysema: centrilobular and paraseptal emphysema. PE, regardless of the grade, was seen: in 189 out of 348 (54.3%) cases in males smokers and in only 2 out of 63 (3.2%) cases in male non-smokers; and in 5 out of 25 (20.0%) in female smokers and in 4 out of 203 (2.0%) in female non-smokers. PE was observed in more than half of male smokers. High incidence of PE was also observed in even younger generation, and severity would progress with advancing age and smoking. Both types of emphysema progress with age and amount of cigarette smoking. (author)

    2012-06-01

    Smoking bans are gaining widespread support in the European Union and other countries. The vast majority of these bans are partial bans given that smoking is still permitted in certain places. This article investigates the role of partial smoking bans in coping with externalities caused by the secondhand smoking problem. Although it is widely known that Pigouvian taxation is superior to a perfect ban, this result does not necessarily carry over to a partial ban because taxes cannot (easily) be differentiated according to location. We show that under an easy and intuitive condition, (1) enacting a partial smoking ban alone always improves social welfare (a) in an unregulated society and (b) even in a regulated society if externalities can be eliminated, and (2) it is ensured that a combination of Pigouvian tax and a partial smoking ban leads to a higher social optimum than implementing corrective Pigouvian taxation alone.

    Full Text Available In this work, the volatile profiles of smoked and non-smoked Iranian rice were identified, and their relative abundance was calculated and compared. Headspace solid-phase microextraction together with gas chromatography-mass spectrometry (SPME-GC-MS were used to extract and identify the volatile compounds. The main groups of volatiles in Iranian rice were aldehydes, ketones, phenol derivatives, furans, linear hydrocarbons, esters and terpenes. The chemical family aldehydes was the most abundant one in the profile of non-smoked rice, while phenol derivatives and furans predominated in smoked samples. This study is the first one reporting comparative data of volatile compounds between smoked and non-smoked Iranian rice.

    2015-01-01

    As a determining factor in various diseases and the leading known cause of preventable mortality and morbidity, tobacco use is the number one public health problem in developed countries. Facing this health problem requires authorities and health professionals to promote, via specific programs, health campaigns that improve patients' access to smoking cessation services. Pharmaceutical care has a number of specific characteristics that enable the pharmacist, as a health professional, to play an active role in dealing with smoking and deliver positive smoking cessation interventions. The objectives of the study were to assess the efficacy of a smoking cessation campaign carried out at a pharmaceutical care center and to evaluate the effects of pharmaceutical care on patients who decide to try to stop smoking. The methodology was an open, analytical, pre-post intervention, quasi-experimental clinical study performed with one patient cohort. The results of the study were that the promotional campaign for the smoking cessation program increased the number of patients from one to 22, and after 12 months into the study, 43.48% of the total number of patients achieved total smoking cessation. We can conclude that advertising of a smoking cessation program in a pharmacy increases the number of patients who use the pharmacy's smoking cessation services, and pharmaceutical care is an effective means of achieving smoking cessation.

    The socio-cultural environment is an important factor involved with the onset of smoking during adolescence. Initiation of cigarette smoking occurs almost exclusively during this stage. In this context we aimed to analyze the association of school and family factors with adolescent smoking by a cross-sectional study of 16 secondary schools randomly selected from the Balearic Islands involved 3673 students and 530 teachers. The prevalence of regular smoking (at least one cigarette per week) was 4.8% among first year students, 11.6% among second year students, 14.1% among third year students, 20.9% among fourth year students and 22% among teachers. Among first and second year students, there were independent associations between regular smoking and adolescents' perception of being allowed to smoke at home, belonging to a single parent family, poor relationship with parents, poor academic performance, lack of interest in studies and teachers' perception of smoking in the presence of pupils. Among third and fourth year students, there were independent associations between regular smoking and poor relationship with parents, adolescents' perception of being allowed to smoke at home, poor academic performance, lack of control over student misbehavior and the school attended. The school policies and practices affect student related health behavior regarding smoking, independent of individual and family factors.

    Compared to adolescents with low exposure to smoking in movies, those with high exposure are about three times as likely to try smoking or become smokers. We have observed this effect in nationally representative samples using cross-sectional and longitudinal designs. This effect remains statistically significant after controlling for numerous other traditional risk factors, such as personality, parenting style, and sociodemographics. Indeed, the movie-smoking exposure effect on adolescent sm...

    Few studies have investigated the complex interactions among the individual- and community-level social risk factors that underlie adolescents’ smoking behaviors. This study investigated whether community-level adult daily smoking prevalence is associated with adolescents’ smoking and whether it moderates the associations between perceived friends’ smoking approval and smoking behavior and adolescents’ own smoking. Self-reported data from 1,190 youths (50.3% female; 13–18 years old) in 50 midsized Californian cities were obtained through telephone interviews. Community characteristics were obtained from 2010 GeoLytics data. Community adult daily smoking prevalence was ascertained from telephone interviews with 8,918 adults conducted in the same 50 cities. Multilevel analyses, controlling for individual and city characteristics, were used to predict adolescents’ past 12-month smoking from perceived friends’ smoking approval and smoking behavior and from community adult daily smoking prevalence. Results showed that perceived friends’ smoking approval and behavior were associated positively with adolescents’ smoking, as was the community-level prevalence of adult daily smoking. Furthermore, the association between perceived friends’ smoking behavior and adolescents’ own smoking was moderated by the prevalence of adult daily smokers in the community. Specifically, the association was stronger in cities with higher prevalence of adult smokers. These results suggest that adult community norms that are more supportive of smoking may enhance the influence of friends’ smoking behavior. Therefore, interventions designed to prevent or reduce youths’ smoking should also focus on reducing smoking by adults. PMID:24241785

    2014-12-01

    Full Text Available In recent years, the increased availability of tobacco products other than conventional cigarettes, the use of puffing topography devices for smoking behaviour studies and the use of biomarkers to study smoke constituents exposure have generated the need for a more comprehensive set of definitions concerning smoking behaviour and exposure to smoke. The definitions offered in this paper are based on many years of practical experience and on consensus within a broad group of scientists working in these areas. It is intended that, with wider and more consistent usage, these definitions should reduce any misunderstandings and facilitate interpretation of future studies.

    Protection from secondhand smoke (SHS) is one of the fundamental principles of the WHO Framework Convention for Tobacco Control. Objective data on SHS exposure in vehicles in South America is scarce. This study aimed to estimate prevalence of smoking inside vehicles. The point prevalence of smoking in vehicles was observed, and a method for estimating smoking prevalence was piloted. We observed 10 011 vehicles. In 219 (2.2%; 95% CI 1.91 to 2.49) of them, smoking was observed, and in 29.2% of these, another person was exposed to SHS. According to the 'expansion factor' we constructed, direct observation detected one of six to one to nine vehicles in which smoking occurred. The observed prevalence of smoking in vehicles (2.2%) could reflect a real prevalence between 12% and 19%. In 29.2% (95% CI 23.6 to 35.5) and 4.6% (95% CI 2.2 to 8.3) of vehicles in which smoking was observed, another adult or a child, respectively, was exposed to SHS. Smoking was estimated to occur in 12%-19% of vehicles, with involuntary exposure in one of three of vehicles observed. These data underscore a need for new public policies to eliminate SHS in vehicles to protect public health. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    This article discusses the role of bidi smoking as a risk factor for lung cancer. A review of the documented evidence is presented. The literature from Pubmed has been searched using the key words 'beedi smoking', 'bidi smoking' and 'lung cancer'. The bibliographies of all papers found were further searched for additional relevant articles. After this thorough search, eight studies were found. The evidence suggests that bidi smoking poses a higher risk for lung cancer than cigarette smoking and risk further increases with both the length of time and amount of bidi smoking. The focus of tobacco control programs should be expanded to all types of tobacco use, including bidis, to reduce the increasing problem of lung cancer.

    It is estimated that 20%-50% of adult smokers reside with children, and the majority of these smokers (70%) continue to smoke inside their homes despite the adverse health effects of second hand smoke (SHS) for their children (Centers for Disease Control and Prevention, 1997). Smoking is more prevalent among parents with lower incomes and less education (U.S. Surgeon General's Report, 2002a). Young persons, ages 20-40 in the family child-rearing stage, are more likely to be smokers. However, they usually have less time and financial resources for quitting smoking. To prevent the adverse health effects of SHS for children, pediatric nurses must provide parents with accurate information on affordable smoking cessation education resources. Evidenced-based smoking cessation guidelines, the cost and efficacy of prescription and over-the-counter (OTC) pharmacological aids, and essential counseling tips for parents are reviewed.

  1. Does smoking tighten the gut?

    1989-01-01

    There is a low prevalence of smoking in ulcerative colitis. The disease often starts or relapses after stopp of smoking. Increased intestinal permeability for harmful substances has been proposed as one causal factor in ulcerative colitis. The authors therefore wanted to study the relationship between smoking and intestinal permeability in healthy subjects. In 25 smoking and 25 non-smoking healthy persons, urine recoveries of two different oral probes, 51 Cr-ethylenediaminetetraacetic acid ( 51 Cr-EDTA) and low-molecular-weight polymers of polyethylene glycol, were measured. The smokers had significantly lower 24-h urine recoveries of 51 Cr-EDTA than the non-smokers. In contrast, 6-h urine recoveries of PEG 400 were not significantly different in smokers and non-smokers. Thus, smoking appears to tighten the gut either by effects on the paracelluar junctions in the intestinal epithelium, or by decreasing the permeability in the distal small bowel and the colon. 21 refs

    BACKGROUND: Smoking is a potential risk factor for psoriasis. Both psoriasis and smoking habits are partly explained by genetic factors. However, twin studies investigating the association between these traits are limited. METHODS: Questionnaire-based data on smoking habits and psoriasis were...... collected for 34,781 twins, aged 20-71 years, from the Danish Twin Registry. A co-twin control analysis was performed on 1700 twin pairs discordant for lifetime history of smoking. Genetic and environmental correlations between smoking and psoriasis were estimated using classical twin modeling. RESULTS......: After multivariable adjustment, age group (50-71 vs. 20-49 years) and childhood exposure to environmental tobacco smoke (ETS) were significantly associated with psoriasis in the whole population (odds ratio [OR] 1.15, 95% confidence interval [CI] 1.02-1.29 [P = 0.021] and OR 1.28, 95% CI 1.10-1.49 [P...

    The study objectives were to determine the effects of smoking machine puffing parameters on mainstream smoke composition and to express those effects as predicting relationships. Forty-eight commercial Philip Morris USA and Philip Morris International cigarettes from international markets and the 1R4F reference cigarette were machine-smoked using smoking conditions defined by the International Organization of Standardization (ISO), the Massachusetts Department of Public Health (MDPH), and Health Canada (HC). Cigarette tobacco fillers were analyzed for nitrate, nicotine, tobacco-specific nitrosamines (TSNA), and ammonia. Mainstream yields for tar and 44 individual smoke constituents and "smoke pH" were determined. Cigarette constituent yields typically increased in the order ISOrelationships were developed between ISO tar and ISO, MDPH, and HC constituent yields and between MDPH tar and HC tar and respective smoking condition yields. MDPH and HC constituent yields could be predicted with similar reliability using ISO tar or the corresponding smoking-condition tar. The reliability of the relationships varied from strong to weak, depending on particular constituents. Weak predicting relationships for nitrogen oxides and TSNA's, for example, were improved with inclusion of tobacco filler composition factors. "Smoke pH" was similar for all cigarettes at any one smoking condition, and overall marginally lower at HC conditions than at ISO or MDPH conditions.

    Tobacco smoking is the main cause of COPD. Smoking cessation is the only therapeutic measure that can cure COPD and prevent this disorder from its chronic progression. Smoking cessation in COPD patients is difficult because most of these patients have specific characteristics that prevent them to quit. Recently, an ERS Task Force has developed a Consensus Document that contains recommendations for helping COPD smokers to quit.

    Cigarette smoke is a concentrated aerosol of liquid particles suspended in an atmosphere consisting mainly of nitrogen, oxygen, and carbon dioxide. While the precise chemical composition of the particulate and gaseous phases is dependent on the characteristics of the cigarette and the manner in which it is smoked, both phases contain tens of hundreds of individual constitutents. Notable among potentially hazardous constituents of smoke are tar, nicotine, carbon monoxide, nitric oxide, hydrogen cyanide, acrolein, benzo(a)pyrene, and N-nitrosamines.

    The effects of marijuana smoke exposure on several measures of tobacco cigarette smoking behavior were examined. Eight healthy adult male volunteers, who smoked both tobacco and marijuana cigarettes, participated in residential studies, lasting 10 to 15 days, designed to measure the effects of marijuana smoke exposure on a range of behavioral variables. Tobacco cigarettes were available throughout the day (9:00 A.M. until midnight). Each day was divided into a private period (9:00 A.M. to 5:00 P.M.), during which subjects were socially isolated, and a social period (5:00 P.M. to midnight), during which subjects could interact. Under blind conditions, subjects smoked placebo and active marijuana cigarettes (0%, 1.3%, 2.3%, or 2.7% delta 9-tetrahydrocannabinol) four times daily (9:45 A.M., 1:30 P.M., 5:00 P.M. and 8:30 P.M.). Each subject was exposed to both placebo and one active dose over 2- to 5-consecutive-day intervals, and dose conditions (i.e., placebo or active) alternated throughout the study. Active marijuana smoking significantly decreased the number of daily tobacco smoking bouts, increased inter-bout intervals and decreased inter-puff intervals. Marijuana decreased the number of tobacco smoking bouts by delaying the initiation of tobacco cigarette smoking immediately after marijuana smoking, whereas decreases in inter-puff intervals were unrelated to the time of marijuana smoking. No consistent interactions between marijuana effects and social or private periods (i.e., time of day) were observed.

    Secondhand smoke (SHS) directly increases exposure to airborne nicotine, tobacco's main psychoactive substance. When exposed to SHS, nonsmokers inhale 60% to 80% of airborne nicotine, absorb concentrations similar to those absorbed by smokers, and display high levels of nicotine biomarkers. Social modeling, or observing other smokers, is a well-established predictor of smoking during adolescence. Observing smokers also leads to increased pharmacological exposure to airborne nicotine via SHS. The objective of this study is to investigate whether greater exposure to airborne nicotine via SHS increases the risk for smoking initiation precursors among never-smoking adolescents. Secondary students ( N = 406; never-smokers: n = 338, 53% girls, mean age = 12.9, SD = 0.4) participated in the AdoQuest II longitudinal cohort. They answered questionnaires about social exposure to smoking (parents, siblings, peers) and known smoking precursors (eg, expected benefits and/or costs, SHS aversion, smoking susceptibility, and nicotine dependence symptoms). Saliva and hair samples were collected to derive biomarkers of cotinine and nicotine. Adolescents wore a passive monitor for 1 week to measure airborne nicotine. Higher airborne nicotine was significantly associated with greater expected benefits ( R 2 = 0.024) and lower expected costs ( R 2 = 0.014). Higher social exposure was significantly associated with more temptation to try smoking ( R 2 = 0.025), lower aversion to SHS ( R 2 = 0.038), and greater smoking susceptibility ( R 2 = 0.071). Greater social exposure was significantly associated with more nicotine dependence symptoms; this relation worsened with higher nicotine exposure (cotinine R 2 = 0.096; airborne nicotine R 2 = 0.088). Airborne nicotine exposure via SHS is a plausible risk factor for smoking initiation during adolescence. Public health implications include limiting airborne nicotine through smoking bans in homes and cars, in addition to stringent restrictions

    During smoked salmon processing, the dark meat along the lateral line is removed before packaging; this by-product currently has little economic value. In this study, the dark meat trim was incorporated into an extruded jerky. Three formulations were processed: 100% smoked trim, 75% : 25% smoked trim : fresh salmon fillet, and 50% : 50% smoked trim : fresh salmon blends (w/w basis). The base formulation contained salmon (approximately 83.5%), tapioca starch (8%), pregelatinized potato starch (3%), sucrose (4%), salt (1.5%), sodium nitrate (0.02%), and ascorbyl palmitate (0.02% of the lipid content). Blends were extruded in a laboratory-scale twin-screw extruder and then hot-smoked for 5 h. There were no significant differences among formulations in moisture, water activity, and pH. Protein was highest in the 50 : 50 blend jerky. Ash content was highest in the jerky made with 100% trim. Total lipids and salt were higher in the 100% trim jerky than in the 50 : 50 blend. Hot smoking did not adversely affect docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) content in lipids from 100% smoked trim jerky. Servings of salmon jerky made with 75% and 100% smoked trim provided at least 500 mg of EPA and DHA. The 50 : 50 formulation had the highest Intl. Commission on Illumination (CIE) L*, a*, and b* color values. Seventy consumers rated all sensory attributes as between "like slightly" and "like moderately." With some formulation and processing refinements, lateral line trim from smoked salmon processors has potential to be incorporated into acceptable, healthful snack products. Dark meat along the lateral line is typically discarded by smoked salmon processors. This omega-3 fatty acid rich by-product can be used to make a smoked salmon jerky that provides a convenient source of these healthful lipids for consumers. © 2012 Institute of Food Technologists®

    Narghile smoking pastes, known as jurak and moassel, are not standardized manufacture. This study aims at drawing the first conclusions on the potential hazards of radioactivity in relation to moassel-narghile smoking. The results indicate the existence of a wide range of variations in the natural radioactivity. The distribution pattern of these natural radio-nuclides, during smoking, between smoke, ash and water filter is unknown, except for 210Po. Radiological dose assessment due to intake of 210Po was calculated and the possible radio-toxicity of the measured radio-nuclides is discussed. Further research in this direction is needed.

    The major objective of this project is to obtain experimental data that are directly applicable to resolving the question of whether cigarette smokers are at greater risk than nonsmokers to potential health effects of inhaled plutonium. Progress was made on two fronts during the past year. The autoradiographic technique developed from detection of plutonium on the interior surface of pulmonary airways (Annual Report, 1978) has been adapted to routine use in examining tracheas and bronchi of rats. Also, dogs exposed to cigarette smoke for over a year after inhalation of plutonium were killed and necropsied

    Secondhand smoke exposure is estimated to account for 3000 cancer deaths per year. While several countries and states in the U.S. have passed comprehensive smoke-free laws to protect all employees, a significant number of workers are still not protected. The purpose of this study was to determine the effects of passing a comprehensive smoking ban that included bars and restaurants on biomarkers of nicotine and carcinogen exposure. The urines of non-smoking employees (N=24) of bars and restaurants that allowed smoking prior to the smoke-free law were analyzed before and after the law was passed in Minnesota. The results showed significant reductions in both total cotinine and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) (free plus glucuronidated) after the ban was instituted. These results provide further support for the importance of protecting employees working in all venues. PMID:20354127

    Tymko, Morgan Anne

    International law guarantees every person the highest attainable standard of health, and this should include protection from the health risks of environmental tobacco smoke. As knowledge of these risks has increased, there has been an incremental expansion of smoking bans in public space. Since 2007, they have extended to the private space of the motor vehicle in an attempt to protect child passengers. This thesis aimed to understand the views and interests of children and youth on vehicular smoking bans, and the extent to which these have been sought after and considered in previous discussions of this policy initiative in Canada. A print media analysis found a lack of concern for children's perspectives. Rights, when considered, were generally those of adults. In focus groups, children discussed the unfairness of exposure to smoke in any space, but especially within the motor vehicle, and articulated a desire for increased participation in decision-making. Keywords: Smoking, smoking bans, rights, children's opinions, vehicles, Canada.

    2014-05-01

    This study examined tobacco smoke pollution (also known as thirdhand smoke, THS) in hotels with and without complete smoking bans and investigated whether non-smoking guests staying overnight in these hotels were exposed to tobacco smoke pollutants. A stratified random sample of hotels with (n=10) and without (n=30) complete smoking bans was examined. Surfaces and air were analysed for tobacco smoke pollutants (ie, nicotine and 3-ethynylpyridine, 3EP). Non-smoking confederates who stayed overnight in guestrooms provided urine and finger wipe samples to determine exposure to nicotine and the tobacco-specific carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone as measured by their metabolites cotinine and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL), respectively. Compared with hotels with complete smoking bans, surface nicotine and air 3EP were elevated in non-smoking and smoking rooms of hotels that allowed smoking. Air nicotine levels in smoking rooms were significantly higher than those in non-smoking rooms of hotels with and without complete smoking bans. Hallway surfaces outside of smoking rooms also showed higher levels of nicotine than those outside of non-smoking rooms. Non-smoking confederates staying in hotels without complete smoking bans showed higher levels of finger nicotine and urine cotinine than those staying in hotels with complete smoking bans. Confederates showed significant elevations in urinary NNAL after staying in the 10 most polluted rooms. Partial smoking bans in hotels do not protect non-smoking guests from exposure to tobacco smoke and tobacco-specific carcinogens. Non-smokers are advised to stay in hotels with complete smoking bans. Existing policies exempting hotels from complete smoking bans are ineffective.

  5. Where is smoking research published?

    Science.gov (United States)

    Liguori, A.; Hughes, J. R.

    1996-01-01

    OBJECTIVE: To identify journals that have a focus on human nicotine/smoking research and to investigate the coverage of smoking in "high-impact" journals. DESIGN: The MEDLINE computer database was searched for English-language articles on human studies published in 1988-1992 using "nicotine", "smoking", "smoking cessation", "tobacco", or "tobacco use disorder" as focus descriptors. This search was supplemented with a similar search of the PSYCLIT computer database. Fifty-eight journals containing at least 20 nicotine/smoking articles over the five years were analysed for impact factor (IF; citations per article). RESULTS: Among the journals with the highest percentage of nicotine- or smoking-focused articles (that is, 9-39% of their articles were on nicotine/smoking), Addiction, American Journal of Public Health, Cancer Causes and Control, Health Psychology, and Preventive Medicine had the greatest IF (range = 1.3-2.6). Among the journals highest in impact factor (IF > 3), only American Journal of Epidemiology, American Review of Respiratory Disease, Journal of the National Cancer Institute, and Journal of the American Medical Association published more than 10 nicotine/smoking articles per year (3-5% of all articles). Of these, only Journal of the American Medical Association published a large number of nicotine/smoking articles (32 per year). CONCLUSIONS: Although smoking causes 20% of all mortality in developed countries, the topic is not adequately covered in high-impact journals. Most smoking research is published in low-impact journals.

    2015-01-01

    Recent legislative successes allowing expanded access to recreational and medicinal cannabis have been associated with its increased use by the public, despite continued debates regarding its safety within the medical and scientific communities. Despite legislative changes, cannabis is most commonly used by smoking, although alternatives to inhalation have also emerged. Moreover, the composition of commercially available cannabis has dramatically changed in recent years. Therefore, developing sound scientific information regarding its impact on lung health is imperative, particularly because published data conducted prior to widespread legalization are conflicting and inconclusive. In this commentary, we delineate major observations of epidemiologic investigations examining cannabis use and the potential associated development of airways disease and lung cancer to highlight gaps in pulmonary knowledge. Additionally, we review major histopathologic alterations related to smoked cannabis and define specific areas in animal models and human clinical translational investigations that could benefit from additional development. Given that cannabis has an ongoing classification as a schedule I medication, federal funding to support investigations of modern cannabis use in terms of medicinal efficacy and safety profile on lung health have been elusive. It is clear, however, that the effects of inhaled cannabis on lung health remain uncertain and given increasing use patterns, are worthy of further investigation. PMID:25996274

    Full Text Available Neuroendocrine cells are dispersed around the body and can be found within the gastrointestinal system, lungs, larynx, thymus, thyroid, adrenal, gonads, skin and other tissues. These cells form the so-called ''diffuse neuroendocrine system'' and tumors arising from them are defined as neuroendocrine tumors (NETs. The traditional classification of NETs based on their embryonic origin includes foregut tumors (lung, thymus, stomach, pancreas and duodenum, midgut tumors (beyond the ligament of Treitz of the duodenum to the proximal transverse colon and hindgut tumors (distal colon and rectum. NETs at each site are biologically and clinically distinct from their counterparts at other sites. Symptoms in patients with early disease are often insidious in onset, leading to a delay in diagnosis. The majority of these tumors are thus diagnosed at a stage at which the only curative treatment, radical surgical intervention, is no longer an option. Due to the increasing incidence and mortality, many studies have been conducted in order to identify risk factors for the development of NETs. Still, little is known especially when it comes to preventable risk factors such as smoking. This review will focus on smoking and its contribution to the development of different subtypes of NETs.

    Smoking is widely used in fish processing for the color and flavor. Smoke flavorings have evolved as a successful alternative to traditional smoking. The hazards of the fish products treated by liquid-smoking process are discussed in this review. The smoke flavoring is one important ingredient in the smoke-flavored fish. This paper gives the definition of smoke flavorings and the hazard of polycyclic aromatic hydrocarbons (PAHs) residue in the smoke flavorings on the market. It gives also an assessment of chemical hazards such as carcinogenic PAHs, especially Benzo-[ a]pyrene, as well as biological hazards such as Listeria monocytogenes, Clostridium botulinum, histamine and parasites in smoke-flavored fish. The limitations in regulations or standards are discussed. Smoke flavored fish have lower content of PAHs as compared with the traditional smoking techniques if the PAHs residue in smoke flavorings is controlled by regulations or standards.

    2015-04-01

    This study investigated the relationship between lay theories of cigarette smoking and expectations to smoke. An incremental lay theory of smoking entails the belief that smoking behavior can change; an entity theory entails the belief that smoking behavior cannot change. Undergraduate nonsmokers and smokers completed a survey that assessed lay theories of smoking and smoking expectations. Results demonstrated that lay theories of smoking were differentially associated with smoking expectations for nonsmokers and smokers: stronger incremental beliefs were associated with greater expectations of trying smoking for nonsmokers but lower expectations of becoming a regular smoker for smokers. Implications for interventions are discussed. © The Author(s) 2013.

Facing this health problem requires authorities and health professionals to promote, via specific programs, health campaigns that improve patients’ access to smoking cessation services. Pharmaceutical care has a number of specific characteristics that enable the pharmacist, as a health professional, to play an active role in dealing with smoking and deliver positive smoking cessation interventions. The objectives of the study were to assess the efficacy of a smoking cessation campaign carried out at a pharmaceutical care center and to evaluate the effects of pharmaceutical care on patients who decide to try to stop smoking. The methodology was an open, analytical, pre–post intervention, quasi-experimental clinical study performed with one patient cohort. The results of the study were that the promotional campaign for the smoking cessation program increased the number of patients from one to 22, and after 12 months into the study, 43.48% of the total number of patients achieved total smoking cessation. We can conclude that advertising of a smoking cessation program in a pharmacy increases the number of patients who use the pharmacy’s smoking cessation services, and pharmaceutical care is an effective means of achieving smoking cessation. Keywords: community pharmacy, health campaign, tobacco cessation, nicotine replacement therapy

    Smoking bans have been implemented in a variety of settings, as well as being part of policy in many jurisdictions to protect the public and employees from the harmful effects of secondhand smoke (SHS). They also offer the potential to influence social norms and the smoking behaviour of those populations they affect. Since the first version of this review in 2010, more countries have introduced national smoking legislation banning indoor smoking. To assess the effects of legislative smoking bans on (1) morbidity and mortality from exposure to secondhand smoke, and (2) smoking prevalence and tobacco consumption. We searched the Cochrane Tobacco Addiction Group Specialised Register, MEDLINE, EMBASE, PsycINFO, CINAHL and reference lists of included studies. We also checked websites of various organisations. Date of most recent search; February 2015. We considered studies that reported legislative smoking bans affecting populations. The minimum standard was having an indoor smoking ban explicitly in the study and a minimum of six months follow-up for measures of smoking behaviour. Our search included a broad range of research designs including: randomized controlled trials, quasi-experimental studies (i.e. non-randomized controlled studies), controlled before-and-after studies, interrupted time series as defined by the Cochrane Effective Practice and Organisation of Care Group, and uncontrolled pre- and post-ban data. One author extracted characteristics and content of the interventions, participants, outcomes and methods of the included studies and a second author checked the details. We extracted health and smoking behaviour outcomes. We did not attempt a meta-analysis due to the heterogeneity in design and content of the studies included. We evaluated the studies using qualitative narrative synthesis. There are 77 studies included in this updated review. We retained 12 studies from the original review and identified 65 new studies. Evidence from 21 countries is

  2. Nabokov's "Torpid Smoke"

    Directory of Open Access Journals (Sweden)

    Leona Toker

    1988-06-01

    Full Text Available Nabokov's short stories are polished self-contained works of art. However, like his novels and poems, they can be profitably read in the light of their place in his general canon. This place is determined by the time when each story was written and by the way in which other works enrich and elucidate the significance of its images. The short fiction of Nabokov's Berlin period has been regarded largely as akin to studies that a painter makes in preparation for a big picture. In some cases, however, the stories seem to serve as safety valves for the urgent material that had to be kept out of the novels in order not to interfere with their design. A case in point is the 1935 story "Torpid Smoke," written at the juncture of Invitation to a Beheading and The Gift . The plight of the protagonist of "Torpid Smoke" is a hybrid of the tendencies manifest in Cincinnatus of Invitation and Fyodor Godunov Cherdyntsev of The Gift : however, unlike Fyodor, this young poet gets no encouragement in his wish to devote himself to literature; unlike Cincinnatus, he cannot reject his environment with a clear conscience. His father, the major obstacle to his literary pursuits, is essentially decent, well-meaning, and pathetically human—a far cry from the obnoxious "parodies" that surround Cincinnatus. The young poet is trapped between the exquisite happiness that accompanies poetic experience and the price that he cannot achieve artistic self-isolation. In a sense, the story dramatizes the conflict between morality and "aesthetic bliss." The imagery of the story ostensibly serves to increase the density of a plausible setting. Actually, the imagery is also functional; it forms a network of parallels and nuances that point both to the genuineness of the young man's talent and to the possible reason for the "puerile" quality of his "perishable" production, viz., to the presences of unprocessed issues whose pressure prevents him from successfully capturing his poetic

    A high proportion of smokers suffer from mental health problems including depression. Despite many of them wanting to stop smoking, low mood adversely affects their ability to quit. To explore the experiences of smokers with self-reported depression, the relationship of smoking with mental health problems and the experiences of smokers while trying to quit. The study also explored what help within the primary care setting could assist in quitting. Participants were recruited from a large general-practice-based smoking cessation trial. Participants who had indicated they were suffering from depression on a self-reported baseline survey were invited to participate. Semi-structured interviews were conducted over the telephone and digitally recorded. The interviews were transcribed and analysed using a phenomenological qualitative approach. Sixteen interviews were conducted (11 females, 5 males). Mood disturbances were frequently reported as triggers for smoking and low mood was seen as a barrier to quitting. Perceived benefits of smoking when depressed were limited and for many, it was a learned response. A sense of hopelessness, lack of control over one's life and a lack of meaningful activities all emerged as important factors contributing to continued smoking. Participants felt that their quit attempts would be aided by better mood management, increased self-confidence and motivation and additional professional support. Smoking and depression were found to be strongly interconnected. Depressed smokers interested in quitting may benefit from increased psychological help to enhance self-confidence, motivation and mood management, as well as a supportive general practice environment.

    Intention to smoke is a valid and reliable factor for predicting future smoking habits among adolescents. This factor, however, has received inadequate attention in Malaysia. The present paper elaborates the prevalence and factors associated with intent to initiate or to cease smoking, among adolescent nonsmokers and smokers in Kota Tinggi, Johor, Malaysia. A total of 2,300 secondary school students aged 13-16 years were selected through a two-stage stratified sampling method. A set of standardized questionnaires was used to assess the smoking behavior among adolescents and the inter-personal and intra-personal factors associated with smoking intention (intention to initiate smoking or to cease smoking). Multivariable logistic regression was used to identify factors related to smoking intention. The prevalence of intention to smoke in the future or to cease smoking among non- smoking adolescents and current smokers were 10.7% and 61.7% respectively. Having friends who smoke, social influence, and poor knowledge about the ill effects on health due to smoking showed significant relationships with intention to smoke in the future among non-smokers. Conversely, perceived lower prevalence of smoking among peers, weak contributory social influence, and greater awareness of the ill effects of smoking are factors associated with the intention to cease smoking sometime in the future. The study found that prevalence of intention to initiate smoking is low among non-smokers while the majority of current smokers intended to cease smoking in the future. Existing anti-smoking programmes that integrate the factors that have been identified in the current study should be put in motion to reduce the prevalence of intention to initiate smoking and increase the intention to cease smoking among adolescents.

  13. Projected Heat Wave Characteristics over the Korean Peninsula During the Twenty-First Century

    2018-02-01

    Climate change is expected to increase temperatures globally, and consequently more frequent, longer, and hotter heat waves are likely to occur. Ambiguity in defining heat waves appropriately makes it difficult to compare changes in heat wave events over time. This study provides a quantitative definition of a heat wave and makes probabilistic heat wave projections for the Korean Peninsula under two global warming scenarios. Changes to heat waves under global warming are investigated using the representative concentration pathway 4.5 (RCP4.5) and 8.5 (RCP8.5) experiments from 30 coupled models participating in phase five of the Coupled Model Inter-comparison Project. Probabilistic climate projections from multi-model ensembles have been constructed using both simple and weighted averaging. Results from both methods are similar and show that heat waves will be more intense, frequent, and longer lasting. These trends are more apparent under the RCP8.5 scenario as compared to the RCP4.5 scenario. Under the RCP8.5 scenario, typical heat waves are projected to become stronger than any heat wave experienced in the recent measurement record. Furthermore, under this scenario, it cannot be ruled out that Korea will experience heat wave conditions spanning almost an entire summer before the end of the 21st century.

  14. Disease emergence in birds: Challenges for the twenty-first century

    Science.gov (United States)

    Friend, Milton; McLean, R.G.; Dein, F.J.

    2001-01-01

    The paper by Hartup et al. (2001) on House Finch (Carpodacus mexicanus) conjunctivitis is an example of the rapid geographic spread that can result from disease emergence in naïve populations. That event was neither novel nor transient relative to its occurrence or effects. Disease emergence and reemergence are hallmarks of the latter part of the twentieth century (Center for Disease Control 1994, Levins et al. 1994, DaSilva and Laccarino 1999, Gratz 1999). Current examples involving domestic animals include the problems in Europe with bovine spongiform encephalopathy (BSE, or “mad cow disease”) (Brown 2001) and foot-and-mouth disease (FMD) (Kitching 1999). Human health has been affected by diseases caused by an array of viruses (Morse 1993, Nichol et al. 1993, Murphy and Nathanson 1994), bacteria (Dennis 1998, DaSilva and Laccarino 1999), rickettsia (Walker and Dumier 1996, Azad et al. 1997), protozoans (Tuerrant 1997, Saini et al. 2000), and metazoan parasites (Hildreth et al. 1991, Gubler 1998), as well as other causes. Acquired immune deficiency syndrome (AIDS) has received the most notoriety of those diseases (Hahn et al. 2000, Schwartlander et al. 2000). A similar pattern exists on a global scale for free-ranging wildlife populations (Table 1) (Friend 1994, 1995; Epstein et al. 1998, Daszak et al. 2000). However, in comparison to disease emergence affecting humans and domestic animals, response to emerging diseases of wildlife is generally superficial. We present concepts and data to support our contention that failure to adequately address disease emergence in free-ranging wildlife is resulting in a diminished capability to achieve and sustain desired geographic distributions and population abundance for species of wild birds, including some threatened and endangered avifauna.For clarity, we define disease and disease emergence in the context of our use of those terms because they are the focus of our comments. Disease is any departure from health (Guralnik 1982); that is, dysfunction contributing to physiological, physical, reproductive, behavioral, or other impairment that reduces the probability of survival of individuals. If enough individuals are affected, the collective effects can reduce the sustainability of the population. Although disease can result from exposure to a wide variety of physical, chemical, and biological agents and other conditions, we focus this paper on microbes and parasites and to overt mortality caused by them. Thus, disease effects presented only represent the proverbial “tip of the iceberg” relative to the challenges wild avifauna face from disease. Our perspective of disease emergence expands the earlier definitions of emerging diseases by others (Centers for Disease Control and Prevention 1994, Morse 1995) to include all species. Our comments are defined by the context of disease occurrences that have increased within the past three decades, or threaten to increase in the near future relative to populations affected, geographic distribution, or magnitude of effects.

    Recent national focus on the value of increasing US supplies of indigenous renewable energy underscores the need for re-evaluating all alternatives, particularly those that are large and well distributed nationally. A panel was assembled in September 2005 to evaluate the technical and economic feasibility of geothermal becoming a major supplier of primary energy for US base-load generation capacity by 2050. Primary energy produced from both conventional hydrothermal and enhanced (or engineered) geothermal systems (EGS) was considered on a national scale. This paper summarizes the work of the panel which appears in complete form in a 2006 MIT report, 'The future of geothermal energy' parts 1 and 2. In the analysis, a comprehensive national assessment of US geothermal resources, evaluation of drilling and reservoir technologies and economic modelling was carried out. The methodologies employed to estimate geologic heat flow for a range of geothermal resources were utilized to provide detailed quantitative projections of the EGS resource base for the USA. Thirty years of field testing worldwide was evaluated to identify the remaining technology needs with respect to drilling and completing wells, stimulating EGS reservoirs and converting geothermal heat to electricity in surface power and energy recovery systems. Economic modelling was used to develop long-term projections of EGS in the USA for supplying electricity and thermal energy. Sensitivities to capital costs for drilling, stimulation and power plant construction, and financial factors, learning curve estimates, and uncertainties and risks were considered.

    2012-01-01

    The increased reliance on simulation classrooms has proven successful in learning skills. Questions persist concerning the ability of technology-driven robotic devices to form and cultivate caring behaviors, or sufficiently develop interactive nurse-client communication necessary in the context of nursing. This article examines the disconnects created by use of simulation technology in nursing education, raising the question: "Can learning of caring-as-being, be facilitated in simulation classrooms?" We propose that unless time is spent with human beings in the earliest stages of nursing education, transpersonal caring relationships do not have space to develop. Learning, crafting, and maturation of caring behaviors threatens to become a serendipitous event or is no longer perceived as an essential characteristic of nursing. Technology does not negate caring-the isolation it fosters makes transpersonal caring all the more important. We are called to create a new paradigm for nursing education that merges Nightingale's vision with technology's promise. © 2012 Wiley Periodicals, Inc.

  3. The New Face of Genetics: Creating A Multimedia Educational Tool for the Twenty-First Century

    Science.gov (United States)

    Fan, Audrey

    In the study of certain genetic conditions, it is important to understand the specific "dysmorphology" associated with them. This describes the unique anatomical manifestations of the genetic condition. Traditionally, students learn about dysmorphology by reading text descriptions or looking at photographs of affected individuals. The New Face of Genetics is a film project that aims to teach students dysmorphology by featuring people who have specific genetic conditions. The goal is to enhance students' understanding of these conditions as well as to impart the humanity and beauty of the people who appear in the film. Students will have the opportunity to see dysmorphic features on the animated human form as well as meet individuals who are living with genetic difference. The target audience includes genetic counseling students and other medical professionals. Three short films were made in this format to demonstrate how this type of educational tool can be made. The featured conditions were Marfan syndrome, Sturge-Weber syndrome and Joubert syndrome. Future work will be carried out by other genetic counseling students who will make additional films based on our templates. A compendium of approximately 20 films will be eventually completed and released to genetic counseling programs and medical schools.

I claim that conceptual art and biological art are two unique spaces within which the understanding of embodiment and disease comes to be shaped actively and reflexively, sometimes on the very level of the materiality of the body, sometimes through the articulation and representation of medical images and technologies. I link these developments to Paul Rabinow's notion of biosociality and argue that the molecularization and geneticization of the medical gaze, conjoined with certain social and cultural shifts, results in the formation of an experimental public of artists, scientists and lay people, all invested in actively shaping the conceptualization of bodies and diseases. This will take me to a consideration of the intertwining of art and medicine beyond the domain of the visual.

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

    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.

  13. Untying the Mediterranean Gordian Knot: A Twenty First Century Challenge for Fisheries Management

    Directory of Open Access Journals (Sweden)

    Ilaria Vielmini

    2017-06-01

    Full Text Available Management of fisheries in the Mediterranean basin has often been described as a unique and complex challenge, due to their multi-specificity, the diversity of gear-types, and the number of nations involved. This perspective has gone hand-in-hand for decades with a lack of strong political will from decision-makers, who have been unwilling to put Mediterranean fisheries management high on their agendas. Over time, exploitation rates of demersal stocks have increased and in 2016, 97% of shared stocks assessed in the Mediterranean were reported to be overfished. An alarm bell about the chronic overfishing of Mediterranean fish stocks was rung by European policy makers in 2015, exactly 20 years after the Code of Conduct for Responsible Fisheries adopted by the Food and Agriculture Organization mandated that states should ensure the sustainable use of fishery resources. In this perspective, we: (i review the context of fisheries management in the Mediterranean; (ii identify the potential factors that may have hindered management and; (iii discuss how the reformed European Union Common Fisheries Policy and the binding commitments laid down in its text may lead to knock-on effects for fisheries management in the international Mediterranean context, if properly implemented. In this line, we also present the example of demersal fisheries management in the Strait of Sicily, which may represent a starting point for science-based management in the Mediterranean.

  14. Reindustrialization: A Challenge to the Economy in the First Quarter of the Twenty-First Century

    Directory of Open Access Journals (Sweden)

    Krawczyński Michał

    2016-01-01

    Full Text Available The weakening EU and US economies in the aftermath of the global crisis of 2007 need an impulse to act for the improvement of their condition. The analysis of the history of the GDP of selected world economies suggests that a remedy for it may be the strengthening of the industrial sector. By strengthening, we mean its growth, that is, building and developing manufacturing plants. Large multinationals have generally been relocating their production to China, where labor costs have traditionally been a couple of times lower than in the US or the EU. However, over the past years, the pay gap between the US and China has narrowed, and transport prices have gone up. These are the reasons why numerous large American companies decided to transfer part of their business processes back to the homeland. Also, the EU has been taking account of the benefits of a stable industry. Therefore, it has launched the strategy of “European industry rebirth” that entails a growth of the industry’s share in the GDP up to the level of 20%. In order for EU countries to be able to attain it, the paper raises the issue of the Industrie 4.0 methodology, premises and guidelines may, to a large extent, contribute to success. The paper also takes an in-depth look at Industrie 4.0 and discusses its pros and cons. We attempt to provide an answer to the question of whether Industrie 4.0 may be a tool for reindustrialization.

    Today's surface ocean is saturated with respect to calcium carbonate, but increasing atmospheric carbon dioxide concentrations are reducing ocean pH and carbonate ion concentrations, and thus the level of calcium carbonate saturation. Experimental evidence suggests that if these trends continue, key marine organisms--such as corals and some plankton--will have difficulty maintaining their external calcium carbonate skeletons. Here we use 13 models of the ocean-carbon cycle to assess calcium carbonate saturation under the IS92a 'business-as-usual' scenario for future emissions of anthropogenic carbon dioxide. In our projections, Southern Ocean surface waters will begin to become undersaturated with respect to aragonite, a metastable form of calcium carbonate, by the year 2050. By 2100, this undersaturation could extend throughout the entire Southern Ocean and into the subarctic Pacific Ocean. When live pteropods were exposed to our predicted level of undersaturation during a two-day shipboard experiment, their aragonite shells showed notable dissolution. Our findings indicate that conditions detrimental to high-latitude ecosystems could develop within decades, not centuries as suggested previously.

  16. Implications of climate change for agricultural productivity in the early twenty-first century.

    Science.gov (United States)

    Gornall, Jemma; Betts, Richard; Burke, Eleanor; Clark, Robin; Camp, Joanne; Willett, Kate; Wiltshire, Andrew

    2010-09-27

    This paper reviews recent literature concerning a wide range of processes through which climate change could potentially impact global-scale agricultural productivity, and presents projections of changes in relevant meteorological, hydrological and plant physiological quantities from a climate model ensemble to illustrate key areas of uncertainty. Few global-scale assessments have been carried out, and these are limited in their ability to capture the uncertainty in climate projections, and omit potentially important aspects such as extreme events and changes in pests and diseases. There is a lack of clarity on how climate change impacts on drought are best quantified from an agricultural perspective, with different metrics giving very different impressions of future risk. The dependence of some regional agriculture on remote rainfall, snowmelt and glaciers adds to the complexity. Indirect impacts via sea-level rise, storms and diseases have not been quantified. Perhaps most seriously, there is high uncertainty in the extent to which the direct effects of CO(2) rise on plant physiology will interact with climate change in affecting productivity. At present, the aggregate impacts of climate change on global-scale agricultural productivity cannot be reliably quantified.

    It is now frequently recommended, that only ecological resources can save us and keep for the mankind more or less contemporary way of living for future. During such consideration it is obviously forgotten that ecological wind and sun have occasional character and that still we do not know how to store great amount of energy. It is also not easy to estimate, what is the maximal capacity of such resources, supposing that we want all such energy use. Work estimate one special case in which all ecological resources are fully correlated-the same wind or sun on all places of local power stations-typically one state or economy. (Author)

  6. Twenty-First Century Energy Policy Making in New Hampshire: Lessons for Collaboration

    Science.gov (United States)

    Herndon, Henry Phillip

    In this thesis I investigate the organizational field that is New Hampshire's energy policy-making community as it engages with the state regulatory institution, the Public Utilities Commission, to grapple the challenges of designing a 21st century electricity marketplace. The Public Utilities Commission structure and function are evolving. Historically, the Commission has used adjudicative proceedings to carry out a ratemaking function for monopoly utilities. The Commission's adjudicative process is evolving to become increasingly collaborative as it begins to carry out its new function of 21st century electricity market design. I analyze both the new structure (collaboration) and the new function (21 st century electricity market design) of the Commission through three in-depth case studies of dockets (policy-making processes): Energy Efficiency Resource Standard, Electric Grid Modernization, and Net Metering. My findings identify ways in which the Public Utilities Commission structure for making energy policy decisions is flexible and may be shaped by stakeholders engaging in policy processes. Stakeholders have the power to collectively design regulatory proceedings to incorporate greater opportunities for collaboration to better suit the challenges posed by a 21st century electricity sector. I provide recommendations on how that redesign should occur.

    Although the latter part of the twentieth century has seen major advances in the understanding of radiation effects, there are many questions which remain unanswered. This paper notes the recent advances in radiation epidemiology and discusses the health effects of ionizing radiation from certain occupations, from nuclear exposures (the A-bomb and nuclear accidents), from medical procedures, from radon gas and from environmental radiation. It concludes with a forward look at what the new millennium may bring in terms of improved understanding and clarification of radiation risks, particularly in key areas such as susceptibility and interaction.

  12. A Painter's View of the Cosmos In the Twenty-first Century

    Science.gov (United States)

    Cro-Ken, K.

    2016-01-01

    I am an ecosystem artist who uses paint to bring nature's “invisible forces” into view. My eco-sensitive palette recreates the push-pull forces that shape and mold all things. As a result, I create microscopic and telescopic views of earth and places scattered throughout our universe. Self-similarity led me to realize that if I want my mind to wonder into the far reaches of the universe, I must draw closer to nature. I show how space looks and appears and, more importantly, how it moves. My speed element palette is a portal through which I peer into the universe at scales great and small using paint as my lens. Microscopes, telescopes, the Internet, and even eyeglasses are portals through which technology affords us the ability to see that which is unseen to the unaided eye. Rather than see the world and then paint, the opposite is true for me. My work is revelatory, not representational and, as such, seeks similar occurrences in nature. Just as a planet's surface is a visual record of past events, so too do speed element experiments reveal traces of the past. It would be more accurate to call a painting that comes to rest a “painted.” It is video that captures images that eluded capture by the canvas and could more accurately be called a “painting. ” Simply put, I manipulate space, time, and matter—and the matter is never just paint.

  10. Extent and ecological consequences of hunting in Central African rainforests in the twenty-first century.

    Abernethy, K A; Coad, L; Taylor, G; Lee, M E; Maisels, F

    2013-01-01

    Humans have hunted wildlife in Central Africa for millennia. Today, however, many species are being rapidly extirpated and sanctuaries for wildlife are dwindling. Almost all Central Africa's forests are now accessible to hunters. Drastic declines of large mammals have been caused in the past 20 years by the commercial trade for meat or ivory. We review a growing body of empirical data which shows that trophic webs are significantly disrupted in the region, with knock-on effects for other ecological functions, including seed dispersal and forest regeneration. Plausible scenarios for land-use change indicate that increasing extraction pressure on Central African forests is likely to usher in new worker populations and to intensify the hunting impacts and trophic cascade disruption already in progress, unless serious efforts are made for hunting regulation. The profound ecological changes initiated by hunting will not mitigate and may even exacerbate the predicted effects of climate change for the region. We hypothesize that, in the near future, the trophic changes brought about by hunting will have a larger and more rapid impact on Central African rainforest structure and function than the direct impacts of climate change on the vegetation. Immediate hunting regulation is vital for the survival of the Central African rainforest ecosystem.

Progress in materials and production processes has played an important part in this development. Yet, there are many challenges before photovoltaics could provide clean, abundant, and cheap energy. Here, we review this research direction, with a focus on the results obtained within a Japan–French cooperation program, NextPV, working on promising solar cell technologies. The cooperation was focused on efficient photovoltaic devices, such as multijunction, ultrathin, intermediate band, and hot-carrier solar cells, and on printable solar cell materials such as colloidal quantum dots.

    Over a course of centuries, various food processing technologies have been explored and implemented to provide safe, fresher-tasting and nutritive food products. Among these technologies, application of emerging food processes (e.g., cold plasma, pressurized fluids, pulsed electric fields, ohmic heating, radiofrequency electric fields, ultrasonics and megasonics, high hydrostatic pressure, high pressure homogenization, hyperbaric storage, and negative pressure cavitation extraction) have attracted much attention in the past decades. This is because, compared to their conventional counterparts, novel food processes allow a significant reduction in the overall processing times with savings in energy consumption, while ensuring food safety, and ample benefits for the industry. Noteworthily, industry and university teams have made extensive efforts for the development of novel technologies, with sound scientific knowledge of their effects on different food materials. The main objective of this review is to provide a historical account of the extensive efforts and inventions in the field of emerging food processing technologies since their inception to present day.

    2015-01-01

    This paper seeks to define concepts such as ‘citizenship’ and ‘global citizenship’ in a democracy and what it means to be ‘a good citizen’. It also seeks to explain that every individual can be ‘a good citizen’ in different situations and scenarios. Of the many agents responsible for the development of an individual, education, together with the home environment and culture, play an important part. Education is also the key to liberty and freedom, while the media is the key to accessing a ...

  15. Coal utilization in the twenty-first century: How much and for how long?

    Gluskoter, H.

    It is projected that coal usage in the US will increase at approximately the historic rate as electricity consumption increases. Because the life expectancy of powerplants and coal mines is in the tens of years, the electricity to be produced from coal in 2001 will be generated in plants currently on line or under construction, and almost all of the coal consumed will come from existing mines. Coal produces two-thirds of the world's electricity and, on a worldwide basis, will continue to be a major source of energy for the remainder of this century and for some time to come. It is the longer term projections of coal utilization, beyond the next few decades, that remain much more difficult to predict. Fossil fuels are present in the Earth in finite amounts and are not renewable on the human scale of existence. Therefore, a shift to other sources of energy must occur eventually. A doubling of population will create a demand for greatly increased energy production. Historically, a 1% increase in world domestic product has been accompanied by a 1% increase in energy consumption. In most regions of the world, coal could supply a major portion of the increased energy and could do so without requiring major technological advances in coal mining and coal utilization technologies. The large, extensive, and accessible resources of coal, the ability to utilize it, and the demand pressures from an expanding population all bode well for the future of coal. However, there are also factors that may contribute to limiting the future use of coal. They include environmental concerns (acid rain, air toxics, and global warming) and the rate at which nonfossil-fuel sources (perhaps solar and nuclear) are developed. Although many of the decisions that will influence the future use of coal will be based on economic and environmental considerations, it is more than likely that politics will also play an important role in all of those decisions

  19. Radiochemistry and associated nuclear chemistry in the beginning of the twenty-first century

    In many countries radiochemistry and associated nuclear chemistry are facing decreasing attention in scientific and technological education and training. In addition, research facilities involving radioactivity are dealing with growing difficulties, e.g. in respect to finances, staff, public support, and legislation. Quite often it is suggested that radiochemistry has matured and does not need any further development. Moreover, it is stated that radiochemical methods are out-run by new, non-nuclear methods, and thus have actually lost their raison d'etre. Altogether this leads to a situation where radioactivity and radiochemistry are partly vanishing both as a science and as a tool. This situation calls for a closer examination for areas where radiochemistry may continue to play a useful, if not a decisive role, and some guidelines were presented how to proceed in the near future. For that purpose a definition of radiochemistry is given to demarcate it from other areas. Nuclear chemistry as an adjacent field is strongly connected with radiochemistry, and in the frame of the presentation a relevant part of it is considered here as integrated in radiochemistry. The various areas of radiochemistry may be classified into three categories, which partly overlap. The first category is the field of the fundamental aspects of radiochemistry itself. This category covers among others nuclear reaction cross-sections, production routes with associated yields and radionuclidic impurities, decay schemes of radionuclides, radiochemical separations, recoil and hot-atom chemistry, isotope effects and fractionation, and interaction of radiation with matter and detection. The second category covers fields where radioactivity is inextricably bound to the subject involved. This holds e.g. for the entire nuclear fuel cycle, study of the very heavy elements (Z > 100), primordial radioactivity on earth, cosmogenic radioactivity in atmosphere and cosmos, and radionuclides for dating. The third category involves radioactivity as an essential part of a technique. Here two different lines are present. First, radioactivity as a source of ionising radiation to alter material characteristics, e.g. for food conservation, polymerisation and crosslinking of plastics, sterilisation, radiotherapy and pain palliation for patients. The other line is the use of radioactivity to get information on systems and materials, for instance radiotracer methods and nuclear reaction or activation techniques. Quite often these nuclear analytical methods may provide unique information, which cannot be obtained or at least not so easily via other non-nuclear techniques. However, quite often it turns out that these nuclear analytical techniques are not sufficiently used, and when used, they are not exploited to the full extent of their potentials. Additional weak point in studies involving nuclear analytical methods is that the line of approach is too much focussed on the results provided by nuclear analytical technique alone, instead of the actual problem at hand. Necessary additional, mostly non-nuclear techniques, to solve the problem at hand adequately are frequently lacking and/or scientific input from experts from the fields involved is often meagre or even absent. Suggestions are given to improve this situation. (author)

  20. Trauma and Memory in Recent Mexican Narrative of the Twenty-First Century

    OpenAIRE

    Cervantes, Judy

    2015-01-01

    In this dissertation I examine the representation of historical events in contemporary narratives. I offer a psychoanalytical approach to the understanding of a history that reappears in the present. I argue that the return of history to consciousness is itself the awakening of a traumatic loss. In the novels examined, history emerges from the ashes of a forgotten past manifesting a return to a wounded memory. My concern with the study of history and trauma is situated in a particular tim...
