    Technological cycles have been characterized as the basis of long and continuous periods economic growth through sustained changes in total factor productivity. While this hypothesis is in part consistent with several theories of growth, the sheer magnitude and length of the economic revolutions experienced by humankind seems to indicate surmise that more attention should be given to the origin of major technological and economic changes, with reference to one crucial question: role of production and use of energy in economic development.

    Nanotechnology is a revolutionary engine that will engender enormous changes in a vast majority of today's industries and markets, while potentially creating whole new industries. The impact of nanotechnology is particularly significant in the electronics industry, which is constantly driven by the need for higher performance, increased functionality, smaller size and lower cost. Nanotechnology can influence many of the hundreds of components that are typically assembled to manufacture modern electronic devices. Motorola manufactures electronics for a wide range of industries and communication products. In this presentation, the typical components of a cellular phone are outlined and technology requirements for future products, the customer benefits, and the potential impact of nanotechnology on many of the components are discussed. Technology needs include reliable materials supply, processes for high volume production, experimental and simulation tools, etc. For example, even routine procedures such as failure characterization may require the development of new tools for investigating nano-scale phenomena. Business needs include the development of an effective, high volume supply chain for nano-materials and devices, disruptive product platforms, and visible performance impact on the end consumer. An equally significant long-term industry need is the availability of science and engineering graduates with a multidisciplinary focus and a deep understanding of the fundamentals of nano-technology, that can harness the technology to create revolutionary products.

    Full Text Available The development of the education system are largely determined by scientific and technical progress. In recent times it is spoken about approach of a new, fourth industrial revolution. According to researchers, this revolution coincides with a series of information revolutions and is based on the development and implementation of new means and technologies of informatization, such as the Internet of things, VR and AR, 3D-printing, and quantum computers. It is obvious that the education system needs to respond to these challenges. For the solution of relevant problems the article describes a number of urgent measures to be taken in education in the coming years. These measures are systematized depending on the factors of the fourth industrial revolution. In particular, special training of teachers, establishment of a closer partnership organizations vocational education with industry, fundamentalization of training of students, is invariant to rapidly changing technologies, and other measures. Special attention is paid to development of information technologies and approaches to the allocation information revolutions. Their change also has an impact on approaches to reforming the education system.

    For decades, America has anticipated the transformational impact of clean energy technologies. But even as costs fell and technology matured, a clean energy revolution always seemed just out of reach. Critics often said a clean energy future would "always be five years away." This report focuses on four technology revolutions that are here today. In the last five years they have achieved dramatic reductions in cost and this has been accompanied by a surge in consumer, industrial and commercial deployment. Although these four technologies still represent a small percentage of their total market, they are growing rapidly. The four key technologies this report focuses on are: onshore wind power, polysilicon photovoltaic modules, LED lighting, and electric vehicles.

    Approaching the marketing and deployment of small, inherently safe reactors from the standpoint of the legal and financial community, the author suggests various ideal planning criteria that should be adhered to by designers and suppliers in order for the new plants to achieve political and financial acceptability. Although new nuclear technology based on those criteria promise to rekindle the prospects for nuclear fission, neither governments nor suppliers are likely to undertake the requisite investments. Rather, the author proposes a private development initiative between the political community, private investors, and would-be suppliers. (author)

  17. Growth in an English population from the Industrial Revolution.

    Mays, S; Brickley, M; Ives, R

    2008-05-01

    The rapid urbanization of the Industrial Revolution in 18th-19th century England presented new health challenges. Our aim is to investigate using English skeletal remains whether the living conditions for an urban working class group in the Industrial Revolution negatively impacted upon their skeletal growth compared with a population from a rural agrarian parish. The Industrial Revolution skeletal material is from St Martin's Churchyard, Birmingham (SMB), West Midlands. It dates primarily from the first half of the nineteenth century when Birmingham was a major manufacturing center. The rural group is from Wharram Percy (WP), North Yorkshire, and dates from 10th-19th century AD. The methodology involves plotting diaphyseal bone lengths versus dental age for subadults. No overall difference was found between the two populations in bone length-for-age among the 2- to 18-year cohort. However the younger parts of the SMB cohort were smaller than at WP; the opposite was true of the older parts of the cohort. Growth rate, as inferred from crosssectional data, appeared greater at SMB than at WP. The only result consistent with expectations is the larger bone dimensions in young children from WP, but this likely reflects prolonged breastfeeding at WP not differences in urban and rural environments. That the deleterious health effects that we know accompanied the major transition in human society from a rural agrarian to an urban industrialized living environment should be little manifest in skeletal endochondral growth data is discouraging for those who would use such methodology to monitor health in earlier populations.

    Baron, L

    1992-09-01

    The "green revolution" was desirable because of increased crop yields, but 25 years later after the results of land degradation, groundwater contamination, and environmentally harmful practices were revealed, there is a return to sustainable agriculture. The aim is to minimize agriculture's harmful effects on the environment and to maintain water ad soil resources. Present and future food production depends on suitable land, water, climate, and finances. Unfortunately, the timing is wrong. Population growth is putting pressure on farmers to increase yields. The current conditions are the 11% of the earth's vegetative land surface has diminished productivity due to human activity. There is loss of biodiversity and genetic material. CAttle grazing is inefficient and adds to desertification; animal waste contributes to pollution. Pesticides and fertilizers are the largest US water pollutants. Sustainable agriculture means new tilling methods, reducing pesticide use, and crop rotation. The National Research Council in 1989 reported on alternative agriculture: 1) making the most of natural biological processes; 2) reducing or eliminating pesticides and other chemicals; 3) conserving soil, water, and energy; and 4) matching crops with land to ensure sustainable production levels. Reeducation is needed. Operation SAVE (Sustainable Agriculture that's Voluntary and Economical) produces an annual directory and guide for farmers adopting new methods. Land trusts and conservation easements are being established to preserve farmland. Reclamation of degraded land is being promoted by distribution of tree seedlings to developing countries. Community supported agriculture groups share in the cost of raising crops and receive organic, fresh produce. There are fears about economic feasibility. Conventional farmers argue for pesticide use to increase yields, but a Cornell University study refutes this for organically grown corn. High technology research is not likely to yield a new

    Li, Chengzhi; Zhang, Dehui; Hu, Danian

    2017-09-01

    This article discusses why Chinese space programs were able to develop to the extent they did during the turbulent decade of the Cultural Revolution (1966-1976). It first introduces briefly what China had accomplished in rocket and missile technology before the Cultural Revolution, including the establishment of a system for research and manufacturing, breakthroughs in rocket technology, and programs for future development. It then analyzes the harmful impacts of the Cultural Revolution on Chinese space programs by examining activities of contemporary mass factions in the Seventh Ministry of Machinery Industry. In the third section, this article presents the important developments of Chinese space programs during the Cultural Revolution and explores briefly the significance of these developments for the future and overall progress in space technology. Finally, it discusses the reasons for the series of developments of Chinese space technology during the Cultural Revolution. This article concludes that, although the Cultural Revolution generated certain harmful impacts on the development of Chinese space technology, the Chinese essentially accomplished their scheduled objectives in their space program, both because of the great support of top Chinese leaders, including the officially disgraced Lin Biao and the Gang of Four, and due to the implementation of many effective special measures.

  1. Where's the revolution? Digital technology and health care in the internet age.

    Science.gov (United States)

    Miller, Edward Alan; West, Darrell M

    2009-04-01

    Despite the growing use of online resources, it is unclear how many Americans are using the World Wide Web for different health-related purposes and whether factors promoting use of the Internet in health care correspond with those affecting more traditional in-person and telemedicine encounters. This research uses a national public opinion survey to examine the degree to which health care consumers communicate through conventional, face-to-face consultation, telemedicine, or digital technology, and the relationship between these means of communication and respondent characteristics. Results indicate that few people are using digital technology to get information, communicate with health personnel, or make online medical purchases. Furthermore, less well educated, lower-income individuals living in rural areas tend to use the health care Internet less than others. Several policy measures need to be undertaken in order to accelerate the appropriate use of digital technology by health care consumers of all kinds. These include improving education and technological literacy and providing access to low-cost digital technology. Without a consumer complement to prevailing efforts to spur health information technology development and implementation on the part of providers, the promise of the digital revolution will continue to be limited to certain better-connected segments of the population.

  2. A low carbon industrial revolution? Insights and challenges from past technological and economic transformations

    International Nuclear Information System (INIS)

    Pearson, Peter J.G.; Foxon, Timothy J.

    2012-01-01

    Recent efforts to promote a transition to a low carbon economy have been influenced by suggestions that a low carbon transition offers challenges and might yield economic benefits comparable to those of the previous industrial revolutions. This paper examines these arguments and the challenges facing a low carbon transition, by drawing on recent thinking on the technological, economic and institutional factors that enabled and sustained the first (British) industrial revolution, and the role of ‘general purpose technologies’ in stimulating and sustaining this and subsequent industrial transformation processes that have contributed to significant macroeconomic gains. These revolutions involved profound, long drawn-out changes in economy, technology and society; and although their energy transitions led to long-run economic benefits, they took many decades to develop. To reap significant long-run economic benefits from a low carbon transition sooner rather than later would require systemic efforts and incentives for low carbon innovation and substitution of high-carbon technologies. We conclude that while achieving a low carbon transition may require societal changes on a scale comparable with those of previous industrial revolutions, this transition does not yet resemble previous industrial revolutions. A successful low carbon transition would, however, amount to a different kind of industrial revolution. - Highlights: ► Investigates lessons for a low carbon transition from past industrial revolutions. ► Explores the implications of ‘general purpose technologies’ and their properties. ► Examines analysis of ‘long waves’ of technological progress and diffusion. ► Draws insights for low carbon transitions and policy.

    Full Text Available The article considers the problem of increasing the technological competitiveness of Ukrainian enterprises under conditions of a new industrial revolution through the development and introduction of advanced converged technologies. The classification of industrial revolutions, namely, industrial, technological, information and Industry 4.0, is presented, and it has been determined that the key factor of the latter is cyber physical systems for introduction of the client-oriented “Internet of Things”. It has been justified that the formation of Industry 4.0 in developed countries will occur through advanced production technologies (APT, which main characteristics are technological substitution, automation, customization, localization and economic efficiency. It has been found that in 2020 the main priority APT will be: systems of production process control; multidimensional modeling of complex products; intelligent production systems and robotics; systems of creation and transformation (growing of material objects and 3D-printing; materials effective in creating perspective actuating devices (compositional and those that exhibit their properties in small-size structures. It has been proved that the recovery of Ukraine’s industry is not possible on the old industrial base, and the creation of a new industry based on APT of Industry 4.0 is possible in the following areas: ICT (primarily in the field of software development; new composite materials with specified properties; industrial nanobiotechnologies (biomedicine and pharmacy, new agricultural technologies; mathematical modeling for creation of intelligent production systems; space research and development (in particular, development of the first stages of heavy missiles. The necessity of elaborating state programs of competitiveness development on the basis of APT, foresight research oftechnology priorities, promoting high-tech exports in Ukraine has been substantiated.

    2017-01-01

    Among preterm infants, 1-2% are born before 32 weeks of gestation or have a birth weight below 1,500 g. They contribute disproportionately to the burden of mortality and morbidity related to preterm birth, whether in the neonatal period or later in life. They are the target population studied in neonatal networks. Improving neonatal care and later outcome is a major issue in public health. Neonatologists, health care providers, public authorities, parents and families, industry, and all organizations dedicated to infant health must bring their efforts together and dedicate their actions in order to do so. Neonatal networks are the strongest platforms through which to achieve this goal. The progressive information technology (IT) revolution is leading to a new approach. The power of search engines and new technological devices opens extraordinary new perspectives in terms of speed, storing, sharing, and innovative approaches in providing health care. However, difficulties are expected with old applications that cannot evolve in the new IT environment. Security and privacy in data collection are future challenges to be addressed. Here, we describe the eNewborn project and its original software. The main functionalities are interactive navigation, harmonization with other formats, linkage with other databases, and strict security and privacy procedures. © 2017 S. Karger AG, Basel.

    2017-10-01

    Revolutionary progress in the photonic technology provides the ability to develop military systems of new properties not possible to obtain with the use of classical technologies. In recent years, this progress has resulted in developing advanced, complex, multifunctional and relatively cheap Photonic Integrated Circuits (PIC) or Hybrid Photonics Circuits (HPC) built of a collection of standardized optical, optoelectronic and photonic components. This idea is similar to the technology of Electronic Integrated Circuits, which has revolutionized the microelectronic market. The novel approach to photonic technology is now revolutionizing the photonics' market. It simplifies the photonics technology and enables creation of technological centers for designing, development and production of advanced optical and photonic systems in the EU and other countries. This paper presents some selected photonic technologies and their impact on such defense systems like radars, radiolocation, telecommunication, and radio-communication systems.

    Full Text Available In Argentina, innovations related to biotechnologies were rapidly adopted while initially there was an absence of a large social debate. To understand this absence, the institutional framework which legitimized technological innovations must be addressed. This framework was undoubtedly one of the conditions of success of the dissemination of the agribusiness model. It´s unfolding also evidences the restructuring of local rural dominant classes that led to the emergency of new social actors. These were the “innovators” gathered in the Argentine Association of No-Tilling Farmers (or AAPRESID.  Here, we analyze how innovations were introduced and legitimated in Argentina. In contrast to what AAPRESID has termed as a “paradigmatic revolution”, we will characterize the introduction of biotechnologies in Argentine agriculture as a “conservative revolution”.

    Directory of Open Access Journals (Sweden)

    O.I. OLADELE

    2010-09-01

    Full Text Available The development and dissemination of sawah rice eco-technology in Nigeria and Ghana as prerequisites for the actualization of green revolution in West Africa were described. It showed that the neglect of the eco-technology and the overemphasis of the biotechnology have rendered the ineffective transferability of the green revolution process from Asia to Africa. The sawah eco-technology increases yield up to 5 t/hm2 through bunding and the use of inlet and outlet connecting irrigation and drainage, which enhances effective water control and management, improves the efficiency of fertilizer, improves nitrogen fixation by soil microbes and algae, increases the use of wetlands, improves soil organic matter accumulation, suppresses weed growth, and enhances immune mechanism of rice through nutrient supply. The current experience has therefore established that the technology overcomes the constraints that have limited the realization of green revolution in West Africa.

  1. From the water wheel to turbines and hydroelectricity. Technological evolution and revolutions

    Science.gov (United States)

    Viollet, Pierre-Louis

    2017-08-01

    Since its appearance in the first century BC, the water wheel has developed with increasing pre-industrial activities, and has been at the origin of the industrial revolution for metallurgy, textile mills, and paper mills. Since the nineteenth century, the water wheel has become highly efficient. The reaction turbine appeared by 1825, and continued to undergo technological development. The impulsion turbine appeared for high chutes, by 1880. Other turbines for low-head chutes were further designed. Turbine development was associated, after 1890, with the use of hydropower to generate electricity, both for industrial activities, and for the benefits of cities. A model ;one city + one plant; was followed in the twentieth century by more complex and efficient schemes when electrical interconnection developed, together with pumped plants for energy storage.

  15. Geoeconomic Uses of Global Warming: The “Green” Technological Revolution and the Role of the Semi-Periphery

    Directory of Open Access Journals (Sweden)

    Diego Hurtado

    2018-03-01

    Full Text Available While some semi-peripheral countries have seen renewable energies as an opportunity to build their industrial and technological capacities, core countries and global governance organizations have been promoting “green growth.” Since the 2008 global financial crisis, global warming has been used as a catalyst for big business. As the global economy may be entering the first stage of a “green” technology revolution, neo-Schumpeterian economists have regained visibility. We intend to show how, as a consequence of the lack of a world-systemic perspective, crucial inconsistencies arise in neo-Schumpeterian contributions that weaken their conceptualization of the role of non-core economies in technological change. We examine the case of the tortuous trajectory of wind energy in Argentina to show the specific organizational, institutional, and macroeconomic constraints faced by a semi-peripheral economy as it attempts to develop its own technological and industrial capacities. The neo-Schumpeterian view of the “green industrial revolution” must be understood as valid only for the core-economy subsystem, which seems to require as well polarization of the world-system through what we call “semi-peripheral neoliberalism,” a peripheralizing force upon the semi-periphery necessary in order to rejuvenate core economies.

    Benagiano, Giuseppe; Bastianelli, Carlo; Farris, Manuela

    2007-03-01

    Modern contraceptive technology is more than a technical advance: it has brought about a true social revolution, the 'first reproductive revolution' in the history of mankind. This latter was followed in rapid succession by other major changes in human reproductive strategies. In the human species, sexual activity began to lose its exclusive reproductive meaning at an early stage of its evolution. Human beings must have practiced non-conceptive sex from the outset and therefore must have had a need to avoid, rather than to seek conception during intercourse from time immemorial. The search for methods to control fertility went on for millennia, but a valid solution was only found during the twentieth century, when the population explosion had forever changed the shape of humanity: in only one century the total population of the planet had grown from some 1.6 billion to more than 6 billion. That increase will remain unique in the history of Homo sapiens. At the global level, contraception provided a tool to deal with overpopulation and, in only 50 years, went a long way towards its resolution. However, to solve the problem, national and international family planning initiatives were required. For individuals, contraception also meant a revolution. It allowed sexual intercourse without reproduction. Only 25 years later, in vitro fertilisation permitted childbearing without sexual intercourse. Other advances followed and now cloning, that is, reproduction without the two gametes, looms on the horizon. Such a series of rapid, major changes in human reproductive strategies has confused many. For this reason, a constructive dialogue between sociology and biology is mandatory. Contraception is a powerful tool to promote equity between sexes; it improves women's status in the family and in the community. Avoiding pregnancy during the teens increases opportunities for a young woman's education, training and employment. By controlling their fertility, women get a chance to

    The wide-spread prevalence of unimproved sanitation technologies has been a major cause of concern for the environment and public health, and China is no exception to this. Towards the sanitation issue, toilet revolution has become a buzzword in China recently. This paper elaborates the backgrounds, connotations, and actions of the toilet revolution in China. The toilet revolution aims to create sanitation infrastructure and public services that work for everyone and that turn waste into value. Opportunities for implementing the toilet revolution include: fulfilling Millennium Development Goals and new Sustainable Development Goals; government support at all levels for popularizing sanitary toilet; environmental protection to alleviate wastewater pollution; resource recovery from human waste and disease prevention for health and wellbeing improvement. Meanwhile, the challenges faced are: insufficient funding and policy support, regional imbalance and lagging approval processes, weak sanitary awareness and low acceptance of new toilets, lack of R&D and service system. The toilet revolution requires a concerted effort from many governmental departments. It needs to address not only technology implementation, but also social acceptance, economic affordability, maintenance issues and, increasingly, gender considerations. Aligned with the ecological sanitation principles, it calls for understanding issues across the entire sanitation service chain. Public-private partnership is also recommended to absorb private capital to make up the lack of funds, as well as arouse the enthusiasm of the public. Copyright © 2017 The Authors.

    The detection of nuclear or radioactive materials for homeland or national security purposes is inherently difficult. This is one reason detection efforts must be seen as just one part of an overall nuclear defense strategy which includes, inter alia, material security, detection, interdiction, consequence management and recovery. Nevertheless, one could argue that there has been a revolution in detection affairs in the past several decades as the innovative application of new technology has changed the character and conduct of detection operations. This revolution will likely be most effectively reinforced in the coming decades with the networking of detectors and innovative application of anomaly detection algorithms.

Conclusion 1417 Acknowledgements 1417 ORCID 1417 References 1417 SUMMARY: Over the last decade, there has been an ongoing revolution in the exploration, manipulation and synthesis of biological systems, through the development of new technologies that generate, analyse and exploit big data. Users of Plant Genetic Resources (PGR) can potentially leverage these capacities to significantly increase the efficiency and effectiveness of their efforts to conserve, discover and utilise novel qualities in PGR, and help achieve the Sustainable Development Goals (SDGs). This review advances the discussion on these emerging opportunities and discusses how taking advantage of them will require data integration and synthesis across disciplinary, organisational and international boundaries, and the formation of multi-disciplinary, international partnerships. We explore some of the institutional and policy challenges that these efforts will face, particularly how these new technologies may influence the structure and role of research for sustainable development, ownership of resources, and access and benefit sharing. We discuss potential responses to political and institutional challenges, ranging from options for enhanced structure and governance of research discovery platforms to internationally brokered benefit-sharing agreements, and identify a set of broad principles that could guide the global community as it seeks or considers solutions. © 2018 The Authors.

    Since the discovery of protein kinase activity in 1954, close to 600 kinases have been discovered that have crucial roles in cell physiology. In several pathological conditions, aberrant protein kinase activity leads to abnormal cell and tissue physiology. Therefore, protein kinase inhibitors are investigated as potential treatments for several diseases, including dementia, diabetes, cancer and autoimmune and cardiovascular disease. Modern semiconductor technology has recently been applied to accelerate the discovery of novel protein kinase inhibitors that could become the standard-of-care drugs of tomorrow. Here, we describe current techniques and novel applications of semiconductor technologies in protein kinase inhibitor drug discovery. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2012-01-01

    The capabilities of information technology (IT) have advanced precipitously in the last fifty years. Many of these advances have enabled new and beneficial applications of IT in dental education. However, conceptually, IT use in dental schools is only in its infancy. Challenges and opportunities abound for improving how we support clinical care, education, and research with IT. In clinical care, we need to move electronic dental records beyond replicating paper, connect information on oral health to that on systemic health, facilitate collaborative care through teledentistry, and help clinicians apply evidence-based dentistry and preventive management strategies. With respect to education, we should adopt an evidence-based approach to IT use for teaching and learning, share effective educational content and methods, leverage technology-mediated changes in the balance of power between faculty and students, improve technology support for clinical teaching, and build an information infrastructure centered on learners and organizations. In research, opportunities include reusing clinical care data for research studies, helping advance computational methods for research, applying generalizable research tools in dentistry, and reusing research data and scientific workflows. In the process, we transition from a focus on IT-the mere technical aspects of applying computer technology-to one on informatics: the what, how, and why of managing information.

    Personalized medicine (PM) aims to establish a new approach in clinical decision-making, based upon a patient's individual profile in order to tailor treatment to each patient's characteristics. Although this has become a focus of the discussion also in the psychiatric field, with evidence of its high potential coming from several proof-of-concept studies, nearly no tools have been developed by now that are ready to be applied in clinical practice. In this paper, we discuss recent technological advances that can make a shift toward a clinical application of the PM paradigm. We focus specifically on those technologies that allow both the collection of massive as much as real-time data, i.e., electronic medical records and smart wearable devices, and to achieve relevant predictions using these data, i.e. the application of machine learning techniques.

    2015-03-01

    Neuroscience is fascinating, mysterious, and truly medicine's "final frontier" but deciphering its marvels has historically been inhibited by its sheer complexity. The recent escalation of global neuroscientific endeavors and vast financial backing from governments, foundations, and industries, however are changing this perspective. The sequencing of the human genome, development of innovative tools for mapping neuronal connectivities, and enhanced resolution capabilities of imaging techniques have made landmark contributions toward advancing neurotechnologies. Nations all around the world have initiated and launched brain mapping projects on such a profound and financially immense scale that research in 2015 and beyond are highly anticipated to revolutionize medicine and our interaction with the technological world. Although neurodiagnostic technology is not the vanguard of research interest in the scientific community, it will certainly ride the coattails of these new neuroscientific endeavors. And, in turn, these advancements will greatly impact how we diagnose, treat, and care for our patients in the future. Therefore, the purpose of this article is not only to introduce current neuroscientific enterprises, but to also explore some of the most interesting and instrumental findings using neurodiagnostic technology over the past year.

    This paper sheds light on the general mechanisms underlying large-scale social and institutional change. We employ an agent-based model to test the impact of authority centralization and social network technology on preference falsification and institutional change. We find that preference falsification is increasing with centralization and decreasing with social network range. This leads to greater cascades of preference revelation and thus more institutional change in highly centralized societies and this effect is exacerbated at greater social network ranges. An empirical analysis confirms the connections that we find between institutional centralization, social radius, preference falsification, and institutional change.

    Full Text Available Economic restructuring since 1989 has created an environment in which this economic branch has been able to expand through private enterprise; involving both the former state monopoly (through the creation and subsequent privatisation of Romtelecom – emerging from the communist PTTR organisation and a fiscal regime conducive to private investment both domestic and foreign; not to mention appropriate regimes of licensing and regulation as well as stimulatory measures to accelerate the absorption of information technology. While development has been very rapid globally, Romania’s progress is particularly striking given the low priority for state investment in the 1980s coupled with the enthusiasm of consumers over the past decade and the commitments made by foreign investors. The paper provides a historical introduction before examining recent developments in telephony (both fixed and mobile, cable television and information technology; emphasising the diversity of methods for Internet access; based on material culled from the economic press throughout the post-1989 period. Attention is given to both domestic and foreign IT companies; noting location policies which emphasise not only Bucharest but also the country’s ‘metropoles’ which are very attractive on account of their accessibility and labour markets.

    2015-05-01

    Thoracoabdominal aortic repair is a high-risk procedure in most experienced centers, not only because of anatomical complexity but also due to the fragility of the patients in whom these aneurysms occur. Such repairs are complex, time-consuming and impose a systemic injury upon the patients, regardless of whether the repair is performed by open surgery or via a fenestrated/branched technique. The substantive risks associated with such repairs include death, dialysis and paralysis. The multilayer flow modulator (MFM) is a disruptive technology which promises a minimally invasive reproducible treatment option, with clinical results demonstrating physiological modulation of the aortic sac with abolition of spinal injury. The mode of action of MFM forces us to completely rethink aneurysm pathogenesis and, consequently, it has been met with much cynicism. We aim to uncloak some of the mystery surrounding the MFM, clarify its mode of action and explore the truth behind its clinical effectiveness.

    Lidström, Suzy; Allen, Roland E.

    2015-03-01

    Fundamental physics, as exemplified by the recently discovered Higgs boson, often appears to be completely disconnected from practical applications and ordinary human life. But this is not really the case, because science, technology, and human affairs are profoundly integrated in ways that are not immediately obvious. We illustrate this by defining a ``Higgs number'' through overlapping activities. Following three different paths, which end respectively in applications of the World Wide Web, digital photography, and modern electronic devices, we find that most people have a Higgs number of no greater than 3. Specific examples chosen for illustration, with their assigned Higgs numbers, are: LHC experimentalists employing the Worldwide Computing Grid (0) - Timothy Berners-Lee (1) - Marissa Mayer, of Google and Yahoo, and Sheryl Sandberg, of Facebook (2) - users of all web-based enterprises (3). CMS and ATLAS experimentalists (0) - particle detector developers (1) - inventors of CCDs and active-pixel sensors (2) - users of digital cameras and camcorders (3). Philip Anderson (0) - John Bardeen (1) - Jack Kilby (2) - users of personal computers, mobile phones, and all other modern electronic devices (3).

    A significant increase in shoot biomass and seed yield has always been the dream of plant biologists who wish to dedicate their fundamental research to the benefit of mankind; the first green revolution about half a century ago represented a crucial step towards contemporary agriculture and the development of high-yield varieties of cereal grains. Although there has been a steady rise in our food production from then onwards, the currently applied technology and the available crop plants will not be sufficient to feed the rapidly growing world population. In this opinion article, we highlight several below-ground characteristics of plants such as root architecture, nutrient uptake and nitrogen fixation as promising features enabling a very much needed new green revolution.

  17. The Impact of Social Networks and Mobile Technologies on the Revolutions in the Arab World—A Study of Egypt and Tunisia

    Directory of Open Access Journals (Sweden)

    Alana Maurushat

    2014-10-01

    Full Text Available Revolts in Tunisia and Egypt have led many observers to speak of the “first digital revolution” in the Arab world. Social media sites, such as Twitter and Facebook, are now recognised as the important tools that facilitated the “Jasmine Revolution”. In fact, the willingness of the Mubarak government to block all internet connection in Egypt has demonstrated the concern over the power of new technologies in facilitating political change. The tenacity of the social movements that are still on-going in the Arab world continues to demonstrate the important role that networked technologies—such as the internet, satellite channels and social networking sites—play in revolutions. The revolutions demonstrate an effective use of social media and other network technologies as an organisational tool, and as a means of asserting pressure on current rulers and future governments. Accordingly, this article seeks to expose freedom of expression as a fundamental democratic principle and the internet network as a vehicle driving the demonstrations in the Arab countries of Tunisia and Egypt.

    Full Text Available Andhra Pradesh is an agrarian state located in peninsular India with semi-arid tropical climate; divided into three geo-political regions viz. Coastal Andhra, Rayalaseema and Telangana. Regional differences in agro climatic conditions and irrigation potential resulted in regional imbalances in overall development. Agricultural production in Andhra Pradesh is dominated by small and marginal farmers who practice traditional mixed farming system. Major changes that took place during green revolution phase lead to increased irrigation potential, shifts in crops and cropping pattern, farm mechanization and fragmentation of land holding had direct impact on livestock sector. Cattle were predominant in the state during pre-green revolution period except in Coastal Andhra. Among cattle 44% were males, emphasizing their role as draft animal. By 2003, it was reduced to 15 %. Among buffaloes, proportion of females and young stock recorded an increase of about 20% indicating shift in farmer’s preference for milch buffaloes. The increase in proportion of male cattle; female and young buffaloes in Telangana indicate that farmers in this region prefer to keep cattle for draft and buffaloes for milk production. Spatial and temporal trends along with shifts in composition in cattle and buffaloes are discussed.

  19. The digital revolution in energy

    International Nuclear Information System (INIS)

    2015-01-01

    The growth of renewable sources of energy on the planet (in particular, solar power) is deeply altering the economics of energy. The decentralization of decision-making, the placing of users at the center of systems, the management of energy consumption in buildings, new forms of mobility... all these are expectations that digital technology can satisfy. Do digital technology and energy naturally converge... or will there be a revolution? For sure, a revolution, but one that has to take place, first of all, in our heads

  20. Quantum revolution

    CERN Multimedia

    CERN Bulletin

    2010-01-01

    The turn of the XXth century witnessed a revolution in physics comparable to Isaac Newton’s discovery of the universal laws of mechanics and of gravitation three centuries earlier. The world required to be described in novel terms, as the immutable, deterministic view of our familiar universe had given way to a new world picture, one which featured chance, flux, and an incessant upsurge of waves of matter. Such a worldview was so radically new and counterintuitive that it gave rise to strong debates, to the effect that Albert Einstein himself tried to oppose it on the grounds that “God does not play dice”. In spite of the intense debates that accompanied its emergence, quantum mechanics quickly proved an incredibly efficacious new tool to understand and to predict a wide array of new phenomena. It was so successful that in no time it broke free from the environment of research labs to become part of daily life, making it possible, for example, to understand why some materials...

    This article argues that technological innovation is transforming the flow of information, the fluidity of social action, and is giving birth to new forms of bottom up innovation that are capable of expanding and exploding old theories of reproduction and resistance because 'smart mobs', 'street knowledge', and 'social movements' cannot be neutralized by powerful structural forces in the same old ways. The purpose of this article is to develop the concept of YPAR 2.0 in which new technologies enable young people to visualize, validate, and transform social inequalities by using local knowledge in innovative ways that deepen civic engagement, democratize data, expand educational opportunity, inform policy, and mobilize community assets. Specifically this article documents how digital technology (including a mobile, mapping and SMS platform called Streetwyze and paper-mapping tool Local Ground) - coupled with 'ground-truthing' - an approach in which community members work with researchers to collect and verify 'public' data - sparked a food revolution in East Oakland that led to an increase in young people's self-esteem, environmental stewardship, academic engagement, and positioned urban youth to become community leaders and community builders who are connected and committed to health and well-being of their neighborhoods. This article provides an overview of how the YPAR 2.0 Model was developed along with recommendations and implications for future research and collaborations between youth, teachers, neighborhood leaders, and youth serving organizations.

    2017-02-01

    In this paper, the energy efficiency of a contemporary Smart Grid that is based on Distributed Renewable Energy Sources (DRES) is examined under the scope of the communication systems utilized between the energy loads and the energy sources. What is evident is that the Internet of Things (IoT) technologies that are based on the existing Web infrastructure can be heavily introduced in this direction especially when combined with long range low bandwidth networking technologies, power line communication technologies and optimization methodologies for renewable energy generation. The renewable energy generation optimization will be based on devices embedded in the PV panels and the wind power generators, which will rely on bidirectional communications with local gateways and remote control stations for achieving energy efficiency. Smart meters and DRES combined with IoT communications will be the enabling technologies for the ultimate fusion of Internet technology and renewable energy generation realizing the Energy Internet.

    2013-06-01

    The iPad and other mobile technologies provide powerful new tools to potentially enhance communication for individuals with developmental disabilities, acquired neurogenic disorders, and degenerative neurological conditions. These mobile technologies offer a number of potential benefits, including: (a) increased awareness and social acceptance of augmentative and alternative communication (AAC), (b) greater consumer empowerment in accessing AAC solutions, (c) increased adoption of AAC technologies, (d) greater functionality and interconnectivity, and (e) greater diffusion of AAC research and development. However, there remain a number of significant challenges that must be addressed if these benefits are to be fully realized: (a) to ensure the focus is on communication, not just technology, (b) to develop innovative models of AAC service delivery to ensure successful outcomes, (c) to ensure ease of access for all individuals who require AAC, and, (d) to maximize AAC solutions to support a wide variety of communication functions. There is an urgent need for effective collaboration among key stakeholders to support research and development activities, and to ensure the successful implementation of mobile technologies to enhance communication outcomes for individuals who require AAC and their families.

  3. After the Biomedical Technology Revolution: Where to Now for a Bio-Psycho-Social Approach to Social Work?

    Science.gov (United States)

    Healy, Karen

    2016-07-01

    In the late twentieth century, the bio-psycho-social framework emerged as a powerful influence on the conceptualisation and delivery of health and rehabilitation services including social work services in these fields. The bio-psycho-social framework is built on a systems view of health and well-being ( Garland and Howard, 2009). The systems perspective encourages medical and allied health professions, including social work, to recognise and to respond to the multiple systems impacting on individual health and well-being ( Engel, 2003). This paper analyses how advances in biomedical technology, particularly in the fields of neuroscience and human genomics, are challenging the bio-psycho-social approach to practice. The paper examines the pressures on the social work profession to embrace biomedical science and points to the problems in doing so. The conclusion points to some tentative ways forward for social workers to engage critically with biomedical advances and to strengthen the bio-psycho-social framework in the interests of holistic and ethical approaches to social work practice.

    Full Text Available Starting from Evangelista Torricelli's pneumatic discoveries, we try to show that the crucial discoveries in pure science associated with the Scientific Revolution, although they may not have found immediate practical applications, have markedly impelled technological progress in the medium term - contrary to the diffused notion which states that the links between science and technology during the modern period have been tenuous, at best. Torricelli's ideas have turned into one of the privileged research areas for then newborn experimental program, actively participating in a process of reformulation in scientific research's epistemological base, which have culminated in steam power productive application.

  7. CRISES AND REVOLUTION

    Directory of Open Access Journals (Sweden)

    Adrián Sotelo Valencia

    2010-01-01

    Full Text Available This article addresses the materialist theory of development and fall of Marxism based on the theory of value as originally considered and presented by Karl Marx in Grundrisse and in Crítica da Economia Política, claiming that the production of value depends on labor force. As it takes place today, capital displaces labor force in every industry, service and activity, country, territory and region all over the world; workers are dismissed and are transferred to speculative activities of the fictional capital. This lesser disposition of labor force eventually harms the mean profit rate and, as time goes by, it provokes a crisis. The present capitalist crisis is resultant from the insufficiency and, to certain extent, to the incapacity of mechanisms from the system to generate enough value production in the labor process, to provide value to the invested capital (in settings of production, raw matter, and in labor force or variable capital; to create more value and to regain increased profit rate. These restraints of the financial capital (fictional capital cause a deviation to the speculative plan and contribute for the formation of tragic speculative bubbles in sectors such as those of housing, energy and food. No matter how much productivity is increased, developing a technological revolution and “sparing labor force”, the reduction of time, socially required for the production of goods and labor force, becomes harder and more marginal. This is the way the capitalist system enters a civilian, structural and organic crisis, as it is now. To go beyond the capital means to construct structures and superstructures of a new non-capitalist society based on a new way to produce, to work and to keep harmonious and friendly human social relations. It is difficult to have a successful revolution if not with the education of its agents, that is, the organized front people, parties and syndicates that will raise the social, political and cultural

  14. An Irish Revolution Without A Revolution

    Directory of Open Access Journals (Sweden)

    Aidan Beatty

    2016-03-01

    Full Text Available There is a conventional view among Irish historians that a revolution occurred in that country between the passing of the Third Home Rule Bill of 1912 and the end of the Civil War in 1923.  The violence of those years, the collapse in support for the Irish Parliamentary Party (IPP, the meteoric rise to power of Sinn Féin, a new sense of meritocracy, a greater sense of democracy and a widespread radicalism; all are seen as elements of a major change in Irish politics and life, a ‘Revolution.’  Drawing on Gramsci's notion of a “revolution without a revolution”, this paper seeks to understand the events in Ireland of 1912-23, not as a sudden rupture with the past but as the culmination of a much longer period of (often British-backed capitalist development in post-Famine Ireland. This paper argues that Irish nationalist politics in the decades before 1912 is better understood via categories such as class, gender, capitalism and the pervasive power of the British state.  As such, as well as pursuing a reassessment of the project of Irish historical development and state-building, this paper also seeks a reassessment of the project of (an equally statist Irish historiography.

  15. "CLASS APPROACH" AND "PROLETARIAN CHARACTER" OF RUSSIAN REVOLUTION OF 1917

    Directory of Open Access Journals (Sweden)

    Эдуард Эдуардович Шульц

    2014-12-01

    Full Text Available Study of the problem of “class character” of 1917’ revolution and competency of the term “proletarian revolution”. The author considers questions of participation of various social groups in the Russian revolution, draws analogies of social composition of previous revolutions, considers the principle of “proletarian revolution”, as an ideology element for positioning of Bolsheviks and power capture. It is necessary to consider that an age, gender and national factor played much bigger role un Russian revolution than class factor. Revolution in Russia in many respects leaned on young generations which made more than a third of the population of the Russian Empire by 1917. In fight against tsarism separate calculation was based on the non-russian population and national suburbs of the empire. The special role in the Russian revolution was played by the peasantry. Revolution happened in the capital (in two capitals in Russia, the peasantry remained indifferent to revolution while Bolsheviks didn't begin to take away from them the food violently. This period:(summer - fall of 1919 became the time of peak of the Civil war. However return of landowners and their claim for property of the land forced peasants to turn bayonets for revolution and the earth and, eventually, to provide to Bolsheviks a victory in the Civil war.

  17. The 1917 Revolution in Tuva

    Directory of Open Access Journals (Sweden)

    Vladimir G. Dazishen

    2017-12-01

    Full Text Available Based on both archival and previously published documents, this article examines the issue of impact that Russia’s revolution of 1917 had on contemporary events in Tuva. Tuva acceded to the USSR in 1944, many years after the Bolshevik revolution and the rise of the Soviet state. However, we postulate that the “Soviet history” of Tuva, just like that of Russia, started in 1917. Soviet historiography prioritized the Great October Socialist revolution, but the events of 1917 began in February. The course of February revolution in Tannu Tuva Uriankhai did not automatically lead to the victory of the Bolsheviks and the establishment of the Soviet power. In spring and summer 1917, revolutionary change in Tuva was largely peaceful and constructive. Supported by the whole Russian population of Tuva, members of the Socialist Revolutionary Party formed the new local government and coopted representatives of Tuvan principalities as partners of the new Russian power. Bolshevik ideas, howsoever high the popularity of their supporters in Tuva might have been, did not find massive endorsement in the region. Consequently, Uriankhai saw no “dual power” (dvoevlastiie in 1917, and the victory of communists in Russia did not mean that the power should transfer to them in Tuva as well. One of the most complex issues of the revolution in the region was incorporating the political system of Tuva into that of the Russian Republic. The complications of the “Uriankhai issue” and the rise of Tuvan separatism did not lead to interethnic conflicts, and the use of force to settle the burning issues was not deemed mandatory. On the whole, both the revolutionary events of 1917 and the vocal presence of all Russian political forces in the region pointed towards the future accession of Tuva into the Russian Republic. Our study made use of sources from the Foreign Policy Archive of the Russian Empire in Moscow, as well as regional archives of Tuva, Novosibirsk

The classical computer that relies on logical gates is out, now quantum properties open the way to new machines that will simulate nature's events exactly, this will be possible because both nature and the machine will be quantum. The machine will mimic nature and some problems like high temperature superconductivity that resist any modelling will be reproduced easily and then put within hand reach to be understood. Another application is quantum imaging based on the property of quantum entanglement. In the case of 2 entangled particle beams, the measurement of the properties of one beam fixes the values on the other beam. In other words, in case of entangled fluctuations, the measurement of the fluctuations on one beam fixes the value of the fluctuations on the other beam and by subtracting them on the second beam, we get a more accurate result: we have made the background noise disappear. Another application, that has already entered our daily life, is the generation of random numbers in a simple way: quantum mechanics states that a photon has a probability of 50 % to be reflected by a semi-reflecting plate and be detected, this experimental setting is a perfect toss play. The most known application of quantum mechanics is cryptography to assure the security of information transfer. Various systems have proved its efficiency but this technology is hampered by the damping of the signal in optical fibers and is reliable on distances shorter than a few hundreds kilometers. (A.C.)

  1. The Chemical Revolution revisited.

    Science.gov (United States)

    Chang, Hasok

    2015-02-01

    I respond to the critical comments by Martin Kusch and Ursula Klein on my account of the Chemical Revolution. I comment along three different lines: descriptive, explanatory, and normative. (1) I agree with Klein that Lavoisier did not introduce drastic changes in chemical ontology, but maintain that there was methodological incommensurability in the Chemical Revolution; in response to Kusch's view, I maintain that Lavoisier's victory was slow and incomplete. (2) Admitting that there were many causes shaping the outcome of the Chemical Revolution, including the convenience of Lavoisier's theoretical scheme and various complicated social factors, I still think that the general rise of compositionism was an important factor. (3) I defend my normative pluralist view on the Chemical Revolution, denying Kusch's argument that chemists had overwhelmingly good reasons to trust Lavoisier and his allies over the phlogistonists. Overall, I agree with Kusch that it would be desirable to have a good descriptive-normative sociological account of the Chemical Revolution, but I also think that it should be an account that allows for divergence in individuals' and sub-communities' self-determination.

      This paper is a continuation of Kantian peace and war analysis, but with other means. The paper is part of an effort to establish a systemic theory of state-formation based on the description of the emergence of a number of functional systems. In a historical perspective the military system...... was dominant in the establishment of the European State-model as well as it has a decisive role in the stabilisation of recent states. Using Niklas Luhmann's system theory that does not describes neither military systems nor the emergence of a organisational system, the present paper outlines a system...... theoretical perspective on the present and historical transformations of military systems. One the one hand the paper offers a systemic criticism of the recent so called revolution in military affairs (RMA), on the other hand the historical establishment of a self-referential form of the military system...

  7. Systems biology: leading the revolution in ecotoxicology.

    Garcia-Reyero, Natàlia; Perkins, Edward J

    2011-02-01

    The rapid development of new technologies such as transcriptomics, proteomics, and metabolomics (Omics) are changing the way ecotoxicology is practiced. The data deluge has begun with genomes of over 65 different aquatic species that are currently being sequenced, and many times that number with at least some level of transcriptome sequencing. Integrating these top-down methodologies is an essential task in the field of systems biology. Systems biology is a biology-based interdisciplinary field that focuses on complex interactions in biological systems, with the intent to model and discover emergent properties of the system. Recent studies demonstrate that Omics technologies provide valuable insight into ecotoxicity, both in laboratory exposures with model organisms and with animals exposed in the field. However, these approaches require a context of the whole animal and population to be relevant. Powerful approaches using reverse engineering to determine interacting networks of genes, proteins, or biochemical reactions are uncovering unique responses to toxicants. Modeling efforts in aquatic animals are evolving to interrelate the interacting networks of a system and the flow of information linking these elements. Just as is happening in medicine, systems biology approaches that allow the integration of many different scales of interaction and information are already driving a revolution in understanding the impacts of pollutants on aquatic systems. © 2010 SETAC.

    This study aims to identify patterns of use and preferences related to technology platforms that could support physical activity (PA) programs in an underserved population. A 29-item questionnaire was administered at 5 health and wellness sites targeting low income communities in Chicago. Frequency tables were generated for Internet, cell phone, and social media use and preferences. Chi-squared analysis was used to evaluate differences across age and income groups. A total of 291 individuals participated and were predominantly female (69.0%). Majority reported incomes less than $30,000 (72.9%) and identified as African American/Black/Caribbean (49.3%) or Mexican/Mexican American (34.3%). Most participants regularly used smartphones (63.2%) and the Internet (75.9%). Respondents frequently used Facebook (84.8%), and less commonly used Instagram (43.6%), and Twitter (20.0%). Free Internet-based exercise programs were the most preferred method to increase PA levels (31.6%), while some respondents (21.0%) thought none of the surveyed technology applications would help. Cell phone, Internet, and social media use is common among the surveyed underserved population. Technology preferences to increase PA levels varied, with a considerable number of respondents not preferring the surveyed technology platforms. Creating educational opportunities to increase awareness may maximize the effectiveness of technology-based PA interventions.

  20. The 'Shale Gas Revolution'. Hype and Reality

    International Nuclear Information System (INIS)

    Stevens, P.

    2010-09-01

    The 'shale gas revolution' - responsible for a huge increase in unconventional gas production in the US over the last couple of years - is creating huge investor uncertainties for international gas markets and renewables and could result in serious gas shortages in 10 years time. This report casts serious doubt over industry confidence in the 'revolution', questioning whether it can spread beyond the US, or indeed be maintained within it, as environmental concerns, high depletion rates and the fear that US circumstances may be impossible to replicate elsewhere, come to the fore. Investor uncertainty will reduce investment in future gas supplies to lower levels than would have happened had the 'shale gas revolution' not hit the headlines. While the markets will eventually solve this problem, rising gas demand and the long lead-in-times on most gas projects are likely to inflict high prices on consumers in the medium term. The uncertainties created by the 'shale gas revolution' are also likely to compound existing investor uncertainty in renewables for power generation in the aftermath of Copenhagen. The serious possibility of cheap, relatively clean gas may threaten investment in more expensive lower carbon technologies.

In Rural areas people use biomass fuels (firewood and dried dung for meeting their energy utilization demands. This demand is fulfilled by deforestation and land degradation which results in different health and societal problems and also cause excessive emission of greenhouse gases. The rural population of developing countries is in dire need of biogas for cooking, lighting, heating and feedstock etc. The biogas production derives from various agricultural resources, such as manure and harvest remains enormously available. Biogas technology represents a sustainable way to produce energy for household, particularly in developing countries. It can be cost-effective and environment friendly technology for the people in rural areas. So, Biogas can be a best substitute of biomass fuels for use in rural areas. This review evaluates the use of biogas in developing rural areas and glances at problems and challenges as well as benefits and success factors.

    This essay examines the ways in which the age of revolutions expanded the repertoire of political ideas and identities available to new and old political subjects. It questions the traditional narrative that replaces a model of old regimes and empires with a new one of imagined unitary nation-states. Instead, it argues that the nature of the political crisis of the Iberian empires gave rise to a reinvention of familiar categories, like monarchy and empire, and sired a wider range of new ones that did not fit the national mold.

  13. Joseph Lister's surgical revolution.

    Toledo-Pereyra, Luis H

    2010-10-01

    Joseph Lister (1827-1912), renowned British surgeon-scientist, introduced to the world the use and appreciation of the antiseptic method for the prevention of wound sepsis. Armed with the ideas of Louis Pasteur (1822-1895) regarding the role of microorganisms in infections or the so-called germ theory of disease, he advanced the surgical field by using antiseptics, such as carbolic acid, in the treatment of contaminated wounds. These developments constituted a real surgical revolution. No breakthrough before Lister's, except perhaps the discovery of anesthesia, had contributed to such an incredible advancement in relationship to the surgical arena. After 1867, the year in which Lister published his remarkable paper in Lancet, it was possible to appropriately treat or prevent wound infections with the use of antiseptics at the site of the operated wound. Lister's method was complicated but produced its desired effect--to diminish wound morbidity and patient mortality. His contribution was secured for future generations and a surgical revolution had begun!

    Fuel poverty is a critical issue for a globally ageing population. Longer heating/cooling requirements combine with declining incomes to create a problem in need of urgent attention. One solution is to deploy technology to help elderly users feel informed about their energy use, and empowered to take steps to make it more cost effective and efficient. This study subjects a broad cross section of energy monitoring and home automation products to a formal ergonomic analysis. A high level task analysis was used to guide a product walk through, and a toolkit approach was used thereafter to drive out further insights. The findings reveal a number of serious usability issues which prevent these products from successfully accessing an important target demographic and associated energy saving and fuel poverty outcomes. Design principles and examples are distilled from the research to enable practitioners to translate the underlying research into high quality design-engineering solutions.

  18. Scrutinizing the epigenetics revolution.

    Science.gov (United States)

    Meloni, Maurizio; Testa, Giuseppe

    2014-11-01

    Epigenetics is one of the most rapidly expanding fields in the life sciences. Its rise is frequently framed as a revolutionary turn that heralds a new epoch both for gene-based epistemology and for the wider discourse on life that pervades knowledge-intensive societies of the molecular age. The fundamentals of this revolution remain however to be scrutinized, and indeed the very contours of what counts as 'epigenetic' are often blurred. This is reflected also in the mounting discourse on the societal implications of epigenetics, in which vast expectations coexist with significant uncertainty about what aspects of this science are most relevant for politics or policy alike. This is therefore a suitable time to reflect on the directions that social theory could most productively take in the scrutiny of this revolution. Here we take this opportunity in both its scholarly and normative dimension, that is, proposing a roadmap for social theorizing on epigenetics that does not shy away from, and indeed hopefully guides, the framing of its most socially relevant outputs. To this end, we start with an epistemological reappraisal of epigenetic discourse that valorizes the blurring of meanings as a critical asset for the field and privileged analytical entry point. We then propose three paths of investigation. The first looks at the structuring elements of controversies and visions around epigenetics. The second probes the mutual constitution between the epigenetic reordering of living phenomena and the normative settlements that orient individual and collective responsibilities. The third highlights the material import of epigenetics and the molecularization of culture that it mediates. We suggest that these complementary strands provide both an epistemically and socially self-reflective framework to advance the study of epigenetics as a molecular juncture between nature and nurture and thus as the new critical frontier in the social studies of the life sciences.

  2. A strategy for obtaining social benefits from the gene revolution

    Directory of Open Access Journals (Sweden)

    L.A.B. de Castro

    2004-10-01

    Full Text Available The strategy described in the present paper offers details about the possibility for Brazil to play a more substantial role in the gene revolution. If successfully applied, the powerful science-based technology currently available in Brazil can contribute to extend the benefits of the gene revolution to the poorest countries, very much like the Green Revolution did in the past, thereby reducing the hunger syndrome which claimed the lives of millions of people in some Asian countries, particularly Pakistan and India, decades ago. In his visit to Brazil in February 2004, Norman Borlaug had the opportunity to witness the success of Brazilian agriculture. At a Conference held at ESALQ - Superior School of Agriculture Luiz de Queiroz in Piracicaba, SP, Brazil, he stated that the 21st century revolution will come from Brazil in the area of agriculture. He also said that reducing hunger is essential for the world to achieve socioeconomic stability. A central question remains unanswered: who will fund this revolution? The FAO 2003-2004 Annual Report listed the barriers preventing the gene revolution from reaching the poorest countries: inadequate regulatory procedures - Intellectual Property Rights and Biosafety, poorly functioning seed delivering systems and weak domestic plant breeding capacity; all are discussed in this paper.

  3. Cold fusion in the context of a scientific revolution in physics: History and economic ramifications

    2006-01-01

    Scientific revolutions have occurred in an approximately 80 year periodicity since 1500. Economic depressions have occurred at an approximately 40-50 year periodicity since 1790, and the economic depressions are a result of the scientific revolutions. The field of cold fusion is a part of a scientific revolution in physics. Understanding cold fusion phenomena in the broader historical context is helpful for understanding the development of the field and the significance of the phenomena technologically and economically. This paper includes a short history of science and of the recent scientific revolution, and includes predictions about the economic consequences of the development of the paradigm. (author)

  4. Revolutions that made the earth

    Lenton, Tim

    2013-01-01

    The Earth that sustains us today was born out of a few remarkable, near-catastrophic revolutions, started by biological innovations and marked by global environmental consequences. The revolutions have certain features in common, such as an increase in the complexity, energy utilization, and information processing capabilities of life. This book describes these revolutions, showing the fundamental interdependence of the evolution of life and its non-living environment. We would not exist unless these upheavals had led eventually to 'successful' outcomes - meaning that after each one, at length, a new stable world emerged. The current planet-reshaping activities of our species may be the start of another great Earth system revolution, but there is no guarantee that this one will be successful. This book explains what a successful transition through it might look like, if we are wise enough to steer such a course. This book places humanity in context as part of the Earth system, using a new scientific synthe...

    How unique and definitive is Euclidean geometry in describing the "real" space in which we live? Richard Trudeau confronts the fundamental question of truth and its representation through mathematical models in The Non-Euclidean Revolution. First, the author analyzes geometry in its historical and philosophical setting; second, he examines a revolution every bit as significant as the Copernican revolution in astronomy and the Darwinian revolution in biology; third, on the most speculative level, he questions the possibility of absolute knowledge of the world. Trudeau writes in a lively, entertaining, and highly accessible style. His book provides one of the most stimulating and personal presentations of a struggle with the nature of truth in mathematics and the physical world. A portion of the book won the Pólya Prize, a distinguished award from the Mathematical Association of America.

    Full Text Available The article discusses the separatist moods among the Georgian population of the Black sea province. The attention is paid to the attempts of the georgian social-democrats to separate the Sochi district from the Russian Empire in 1905–1907 years. Among the materials are the archival documents of central and regional archives, namely the state archive of the Russian Federation, state archive of the Krasnodar Krai, the documentation center of contemporary history of Krasnodar Krai, the archival departments of Sochi administration and the historical museum of Sochi. The methodological basis of work based on the principles of objectivity and historicism, suggesting an unbiased approach to the analysis of the studied problems, as well as the critical attitude towards the sources. In conclusion, the authors stated that the social democrats used various methods of dealing with the existing regime, such as the destabilization of public-political situation, expressed in discrediting the Russian administration, provoking ethnic conflicts, the elimination of competitors in wage employment in the trade, physical violence against undesirable persons, the bullying of political opponents, taking money from the haves of the population, and collectively, the escalation of social tensions that eventually led to an armed clash with the authorities.

    If we define scientific revolutions as changes of scientists' ontologies, types of causal explanation, and paradigmatic types of methods and instruments, Antoine-Laurent Lavoisier's contribution to chemistry did not amount to a scientific revolution. Contrary to the received view that Lavoisier initiated a "chemical revolution," which is accepted by Chang and Kusch, I argue that Lavoisier shared with the phlogistonists their "flat ontology" of chemical substance, established decades before the 1770s, their types of explaining chemical transformation, and their quantitative methods. Based on my historical reconstruction, I criticize Chang's argument that the late eighteenth-century phlogistic systems and Lavoisier's system belonged to two different theoretical traditions. As a consequence, I also question Chang's argument that the acceptance of Lavoisier's system can be explained in terms of dominance of "compositionism" over "principlism."

  19. Trends in publications in fluvial geomorphology over two decades: A truly new era in the discipline owing to recent technological revolution?

    Science.gov (United States)

    Piégay, Hervé; Kondolf, G. Mathias; Minear, J. Toby; Vaudor, Lise

    2015-01-01

    Trends in the field of fluvial geomorphology have been reviewed by a number of authors, who have emphasized the dramatic change occuring in the field in the last two decades of the twentieth century, largely as a result of technological advances. Nevertheless, no prior authors have systematically compiled data on publications in fluvial geomorphology over a long period and statistically analyzed the resulting data set. In this contribution we present a quantitative analysis of fluvial geomorphology papers published in the twenty-two-year period 1987–2009 in five journals of the discipline with a more specific focus on Geomorphology and Earth Surface Processes and Landforms (ESPL), identifying authorships, geographic origin of authors, and spatial and temporal scales covered. We also documented the tools employed, demonstrating the transformation of the field with the emergence of new tools over this period, and conducted a cluster to highlight links between tools and a set of factors (country of author's origin, journals, time, and spatial and temporal scales). Of the 1717 papers published in the five journals during this period, the results showed an increased diversity in the nationality of the first author, mainly when dealing with present time scale, and channel feature. Our data show a significant change in methods used in the field as a result of the increase in data availability and new sources of information from remote sensing (ground, airborne and, satellite). Clearly, a new era in knowledge production is observed since 2000, showing the emergence of a second period of active quantification and an internationalization of the fields.

  1. A Short (Personal) Future History of Revolution 2.0.

    Science.gov (United States)

    Spellman, Barbara A

    2015-11-01

    Crisis of replicability is one term that psychological scientists use for the current introspective phase we are in-I argue instead that we are going through a revolution analogous to a political revolution. Revolution 2.0 is an uprising focused on how we should be doing science now (i.e., in a 2.0 world). The precipitating events of the revolution have already been well-documented: failures to replicate, questionable research practices, fraud, etc. And the fact that none of these events is new to our field has also been well-documented. I suggest four interconnected reasons as to why this time is different: changing technology, changing demographics of researchers, limited resources, and misaligned incentives. I then describe two reasons why the revolution is more likely to catch on this time: technology (as part of the solution) and the fact that these concerns cut across social and life sciences-that is, we are not alone. Neither side in the revolution has behaved well, and each has characterized the other in extreme terms (although, of course, each has had a few extreme actors). Some suggested reforms are already taking hold (e.g., journals asking for more transparency in methods and analysis decisions; journals publishing replications) but the feared tyrannical requirements have, of course, not taken root (e.g., few journals require open data; there is no ban on exploratory analyses). Still, we have not yet made needed advances in the ways in which we accumulate, connect, and extract conclusions from our aggregated research. However, we are now ready to move forward by adopting incremental changes and by acknowledging the multiplicity of goals within psychological science. © The Author(s) 2015.

  6. [The beginning of the Cuban demographic revolution].

    Hernandez Castellon, R

    1981-01-01

    The characteristics of the Cuban demographic revolution associated with the main economic, political, and social changes in the country are analyzed. The authors begin with a brief historical outline of the political-economic situation in the country in the middle of the 19th century. There is emphasis on the dependency of the Cuban economy and its monoproducer nature (with sugar being the major export). This was due to the Spanish colonization and to the subsequent American neocolonization. The discovery of the cause for yellow fever by a Cuban physician and the sanitation campaign conducted by the Americans contributed to a diminishing of mortality. A great migratory flow occurred due to the price of sugar in the world market. This must have influenced Cuban demographic patterns which are a major factor linked to the demographic revolution. The influence on proliferation of urbanization and educational trends is emphasized. The low participation in economic activities of women during the early part of the century did affect fertility levels. The trends in mortality throughout the period 1907-43 are pointed out. It was found that 1 major aspect which had a bearing on Cuban demographic patterns was the 2 large migratory flows. An analysis of growth rates in the population--which also confirms the demographic changes in Cuba--is presented. It is concluded that the 4th decade of this century witnessed Cuba's entry in a new stage of the demographic revolution, a stage in which decreased fertility and mortality go together to create a new period.

    2009-11-01

    This special section on Nanophotonics and Metamaterials is a follow-up to the second European Topical Meeting of the NANOMETA series of meetings (see www.nanometa.org) which took place on 5-8 January 2009, in Seefeld, Austria. The main idea of the first NANOMETA meeting held in 2007 was to bring together the mature community of microwave electrical engineers with the emerging community of photonics researchers interested in the physics of light coupled to nanostructures. In recent years the research landscape has shifted dramatically. A wider proliferation of nanofabrication techniques such as electron beam lithography, nanoimprint and focused ion beam milling, diagnostics techniques such as near-field scanning imaging, cathodoluminescence with nanoscale resolution and micro-spectrometry, and the availability of affordable broadband and ultrafast optical sources, have moved the research focus of the NANOMETA community to the optical domain. Quite naturally the ideas of the nonlinearity of materials and the coherency of light in the nanoscale realm have been widely discussed. Driven by the dream of untapped device and material functionality, nonlinear and switchable nanophotonic devices and photonic metamaterials, along with the concept of tailoring the electromagnetic space with metamaterials, appear to be the main avenues along which the subject will develop in the coming years. Indeed, in the last 20 years photonics has played a key role in creating the world as we know it, with enormous beneficial social impact worldwide. It is impossible to imagine modern society without the globe-spanning broadband internet and mobile telephony made possible by the implementation of optical fibre core networks, optical disc data storage (underpinned by the development of compact semiconductor lasers), modern image display technologies and laser-assisted manufacturing. We now anticipate that the next photonic revolution will continue to grow, explosively fuelled by a new

    Rescigno, Maria

    2017-09-01

    Scientific progress is characterized by important technological advances. Next-generation DNA sequencing has, in the past few years, led to a major scientific revolution: the microbiome revolution. It has become possible to generate a fingerprint of the whole microbiota of any given environment. As it becomes clear that the microbiota affects several aspects of our lives, each new scientific finding should ideally be analyzed in light of these communities. For instance, animal experimentation should consider animal sources and husbandry; human experimentation should include analysis of microenvironmental cues that might affect the microbiota, including diet, antibiotic, and drug use, genetics. When analyzing the activity of a drug, we should remember that, according to the microbiota of the host, different drug activities might be observed, either due to modification or degradation by the microbiota, or because the microbiota changes the immune system of the host in a way that makes that drug more or less effective. This minireview will not be a comprehensive review on the interaction between the host and microbiota, but it will aim at creating awareness on why we should not forget the contribution of the microbiota in any single aspect of biology. © 2017 WILEY-VCH Verlag GmbH & Co.

  16. The Spaceflight Revolution Revisited

    Science.gov (United States)

    Bainbridge, William Sims

    2005-01-01

    This essay will first consider whether technological breakthroughs in space technology and the rational motives of ordinary institutions have the capacity to break out of this relatively static situation. Then we will survey the roles that social movements of various kinds might play and conclude with an examination of one particular nascent movement that might possibly build the foundation for a spacefaring civilization. A third of a century ago, practical nuclear fission rockets were under development, but this approach now seems environmentally unacceptable. It is hard to devise a more environmentally benign propellant than the hydrogen and oxygen used by the main engines of the Space Shuttle. There is some hope that nanotechnology will save the day with materials based on carbon nanotubes that are vastly stronger yet lighter than metals.6 However, the X-33 failure shows that it is not easy to work with radically new structural materials in demanding aerospace applications, and we may be many decades away from being able to manufacture propellant tanks, wings, and other large structures from carbon nanotubes. Satellites in low-Earth and synchronous orbit are of great importance in the collection and distribution of information, thus essential to the information economy. The wide range of civilian applications includes telephone, data transmission, television, navigation, weather observation, agriculture monitoring, and prospecting for natural resources.8 The technology is largely perfected, and incremental progress can be achieved by improvement in information systems and simply by investing in more relatively small satellites of the kinds we already have.

    Full Text Available Over the recent years, the Petersen diagram for classical pulsators, Cepheids and RR Lyr stars, populated with a few hundreds of new multiperiodic variables. We review our analyses of the OGLE data, which resulted in a significant extension of the known, and in the discovery of a few new and distinct forms of multiperiodic pulsation. The showcase includes not only radial mode pulsators, but also radial-non-radial pulsators and stars with significant modulation observed on top of the beat pulsation. First theoretical models explaining the new forms of stellar variability are briefly discussed.

    Will developing countries adopt policies that promote the planting of genetically modified (GM) crops, or will they select policies that slow the spread of the GM crop revolution? The evidence so far is mixed. In some prominent countries such as China, policies are in place that encourage the independent development and planting of GM crops. Yet in a number of other equally prominent countries the planting of GM crops is not yet officially approved. The inclination of developing countries to ...

  6. Arab revolutions and shale gas: an explosive mix

    International Nuclear Information System (INIS)

    Boncourt, Maite de

    2013-01-01

    The author comments the critical situation of Arab countries which are traditionally oil and gas producers, but have to face political and social revolutions, and also an energy revolution with the emergence of shale gas and oil, and more generally of new non-conventional energy resources. This energy revolution results in a new deal, and threatens the strategic role of the region with respect to world energy supply. While recalling levels of hydrocarbon and gas production and reserves, and the share in world production of Arab countries, the author discusses to which extent non conventional hydrocarbons are actually a threat for these producers: significant reduction of exports towards the USA, structural upheaval and uncertainty of energy markets, impact on the whole value chain of the world oil industry. The author outlines that the OPEC is progressively loosing its power and influence, and is unable to choose or decide whether to increase or decrease production. Moreover, different political instabilities stopped reforms and investments in Arab countries: revolutions, domestic political tensions, civil war. The challenge could be the ability to make a move on Asian markets, and to implement reforms in order to attract capitals and new technologies

    Wearable technology may provide an integral part of the solution for providing health care to a growing world population that will be strained by a ballooning aging population. By providing a means to conduct telemedicine-the monitoring, recording, and transmission of physiological signals from outside of the hospital-wearable technology solutions could ease the burden on health-care personnel and use hospital space for more emergent or responsive care. In addition, employing wearable technology in professions where workers are exposed to dangers or hazards could help save their lives and protect health-care personnel.

    Hassell, M E C J; Grundeken, M J D; Delewi, R; Wykrzykowska, J J; Piek, J J

    2013-04-01

    After the introduction of coronary balloon angioplasty, bare-metal, and drug-eluting stents, fully bioresorbable scaffolds (BRS) could be the fourth revolution in interventional cardiology. The BRS technology shares the advantages of metallic stents regarding acute gain and prevention of acute vessel occlusion by providing transient scaffolding, while potentially overcoming many of the safety concerns of drug-eluting stents. Furthermore, without a permanent metallic cage, the vessel could remodel favourably and atherosclerotic plaques could regress in the long-term. This attracted increased interest and several BRS have been developed. In this review we will describe all BRS which are thus far clinically evaluated and provide an overview of ongoing clinical studies. Although the technology seems to be very promising, more studies including patients with more complex lesions are needed to evaluate whether the BRS can be used in daily clinical practice and if it is indeed becoming a new interventional revolution.

  9. Revolutions and shifting paradigms in human factors & ergonomics.

    Science.gov (United States)

    Boff, Kenneth R

    2006-07-01

    The "Revolution in Information Technology" has spawned a series of transformational revolutions in the nature and practice of human factors and ergonomics (HFE). "Generation 1" HFE evolved with a focus on adapting equipment, workplace and tasks to human capabilities and limitations. Generation 2, focused on cognitive systems integration, arose in response to the need to manage automation and dynamic function allocation. Generation 3 is focused on symbiotic technologies that can amplify human physical and cognitive capabilities. Generation 4 is emergent and is focused on biological enhancement of physical or cognitive capabilities. The shift from HFE Generations 1 and 2 to Generations 3 and 4 profoundly alters accepted boundary constraints on the adaptability of humans in complex systems design. Furthermore, it has opened an ethical divide between those that see cognitive and physical enhancement as a great benefit to society and those who perceive this as tampering with the fundamentals of human nature.

    Science.gov (United States)

    Turvey, Carolyn; Fortney, John

    2017-10-16

    This article discusses recent applications in telemedicine to promote the goals of population health and population management for people suffering psychiatric disorders. The use of telemedicine to promote collaborative care, self-monitoring and chronic disease management, and population screening has demonstrated broad applicability and effectiveness. Collaborative care using videoconferencing to facilitate mental health specialty consults has demonstrated effectiveness in the treatment of depression, PTSD, and also ADHD in pediatric populations. Mobile health is currently being harnessed to monitor patient symptom trajectories with the goal of using machine learning algorithms to predict illness relapse. Patient portals serve as a bridge between patients and providers. They provide an electronically secure shared space for providers and patients to collaborate and optimize care. To date, research has supported the effectiveness of telemedicine in promoting population health. Future endeavors should focus on developing the most effective clinical protocols for using these technologies to ensure long-term use and maximum effectiveness in reducing population burden of mental health.

  15. No sire, it's a revolution.

    Moccia, P

    1990-09-01

    In much the way 18th century France was ripe for a revolution, so are the two social systems within which we live and work: health care and higher education. In health care, too many are suffering so that a few might live lives of luxury. Higher education is structured so as to reproduce a social order of class privilege and patriarchal values. For a complex set of reasons, (some known to us, many more beyond our consciousness) we have chosen higher education and nursing education as our arena--as the place where we might contribute to the world order, to our society, to individuals and communities who are striving to be healthy. Our project, then, is to enable others so that they might enable still others: to teach and learn with our students who are our colleagues in creating a future; to teach and learn in caring ways that will serve as prototypes for caring communities. To those who would dismiss the curriculum revolution as a fad and those involved it as aging malcontents, I refer them to the diaries of Governor Morris, an American guest of Marie Antoinette who was at Versailles during the months before the fall of the Bastille on July 14, 1789: Yesterday, it was the Fashion at Versailles not to believe that there had been any disturbances at Paris. I presume this Day's Transactions will induce a Conviction that all is not perfectly quiet (Pernoud, 1960, p. 45).

    Full Text Available Change and continuity are characteristics of human history. Strategic change in any society has significant impacts that becomes reference points for similar transformation in the near future. Fundamentally, the numerous internal upheavals that characterized North Africa and Middle East that culminated in a change of government in these countries has raised fundamental question about subject of change and revolution. Such questions include: is every change a revolution and does every revolution culminate in a change? What are the distinguishing features of change and the significance of such change for contemporary international politics? Using secondary data derived from books, and journals, the paper therefore examines the revolution and change in international politics drawing from historical examples of America and France Revolution. Also, noting the causes and implications of these of revolution on International Relations. It also seeks to distinguish between socio-political upheaval and internal disruptions that may culminate in change from revolution, that is, a vital change that affects institution, structure and value system of a society. The paper recommends a cautious use of the term revolution from change of government.

    Antonya, C.

    2017-12-01

    Optical tracking of users and various technical systems are becoming more and more popular. It consists of analysing sequence of recorded images using video capturing devices and image processing algorithms. The returned data contains mainly point-clouds, coordinates of markers or coordinates of point of interest. These data can be used for retrieving information related to the geometry of the objects, but also to extract parameters for the analytical model of the system useful in a variety of computer aided engineering simulations. The parameter identification of joints deals with extraction of physical parameters (mainly geometric parameters) for the purpose of constructing accurate kinematic and dynamic models. The input data are the time-series of the marker’s position. The least square method was used for fitting the data into different geometrical shapes (ellipse, circle, plane) and for obtaining the position and orientation of revolute joins.

    2011-12-09

    Wind energy development in the offshore environment can have both direct and indirect effects on wildlife, yet little is known about most species that use near-shore and offshore waters due in part to the difficulty involved in studying animals in remote, challenging environments. Traditional methods to characterize offshore wildlife populations include shipboard observations. Technological advances have provided researches with an array of technologies to gather information about fauna from afar. This report describes the use and application of radar, thermal and optical imagery, and acoustic detection technologies for monitoring birds, bats, and marine mammals in offshore environments.

    2011-07-01

    We estimate the trend in average height of the population of the French province Orleans from 1715 to the beginning of the 19th century using data on recruits who were drafted either through a lottery system or through general conscription. After controlling for age, residence, and occupation, we find a general decline in the biological standard of living in the decades before the French Revolution. The results support a Ricardian-Malthusian interpretation of the causes of the French Revolution. In the debate 'Revolution de la misère ou de la prospérité' our findings support the side which argues that the French Revolution was a culmination of a long-lasting economic malaise during the final phases of the Ancien Régime.

  6. A demographic projection of the contribution of assisted reproductive technologies to world population growth.

    Science.gov (United States)

    Faddy, Malcolm J; Gosden, Matthew D; Gosden, Roger G

    2018-04-01

    Enormous unmet needs for infertility treatment exist because access to assisted reproductive technologies is demographically skewed. Since the first IVF baby in 1978, the number of people conceived by reproductive technology has grown much faster than expected, reaching several million today and rapidly approaching 0.1% of the total world population. As more patients build families, and their children in turn become parents, the number owing their existence to assisted reproductive technologies, either directly or indirectly, will expand tremendously in future decades, but no attempts have been made hitherto to project the magnitude. We have projected growth to the year 2100, along with the fractional contribution to world population. The chief variable driving growth is access to fertility services. If it stagnates at current levels of about 400,000 babies per year, an estimated 157 million people alive at the end of the century will owe their lives to assisted reproductive technologies (1.4% of global population), but at an arbitrary upper limit of 30,000 extra births annually there will be 394 million additional people alive (3.5%). As the conquest of infertility continues, individuals who owe their lives to assisted reproductive technologies will quietly make a significant contribution to demographic growth as well as social progress.

    Graham, Garth N; Ostrowski, MaryLynn; Sabina, Alyse B

    2016-11-01

    Health care disparities and high chronic disease rates burden many communities and disproportionally impact racial/ethnic populations in the United States. These disparities vary geographically, increase health care expenses, and result in shortened lifespans. Digital technologies may be one tool for addressing health disparities and improving population health by increasing individuals' access to health information-especially as most low-income U.S. residents gain access to smartphones. The Aetna Foundation partners with organizations to use digital technologies, including mobile applications, data collection, and related platforms, for learning and sharing. Projects range from the broad-childhood education, lifestyle modification, health IT training, and nutrition education, to the specific-local healthy foods, stroke rehabilitation, and collection of city-level data. We describe our approaches to grantmaking and discuss lessons learned and their implications. When combined with sound policy strategies, emerging, scalable, digital technologies will likely become powerful allies for improving health and reducing health disparities.

  8. Coevolution of adaptive technology, maladaptive culture and population size in a producer-scrounger game.

    Science.gov (United States)

    Lehmann, Laurent; Feldman, Marcus W

    2009-11-07

    Technology (i.e. tools, methods of cultivation and domestication, systems of construction and appropriation, machines) has increased the vital rates of humans, and is one of the defining features of the transition from Malthusian ecological stagnation to a potentially perpetual rising population growth. Maladaptations, on the other hand, encompass behaviours, customs and practices that decrease the vital rates of individuals. Technology and maladaptations are part of the total stock of culture carried by the individuals in a population. Here, we develop a quantitative model for the coevolution of cumulative adaptive technology and maladaptive culture in a 'producer-scrounger' game, which can also usefully be interpreted as an 'individual-social' learner interaction. Producers (individual learners) are assumed to invent new adaptations and maladaptations by trial-and-error learning, insight or deduction, and they pay the cost of innovation. Scroungers (social learners) are assumed to copy or imitate (cultural transmission) both the adaptations and maladaptations generated by producers. We show that the coevolutionary dynamics of producers and scroungers in the presence of cultural transmission can have a variety of effects on population carrying capacity. From stable polymorphism, where scroungers bring an advantage to the population (increase in carrying capacity), to periodic cycling, where scroungers decrease carrying capacity, we find that selection-driven cultural innovation and transmission may send a population on the path of indefinite growth or to extinction.

    Tao Zhang; Mustiere, Fred; Micheyl, Christophe

    2016-08-01

    The first revolution in hearing aids came from nonlinear amplification, which allows better compensation for both soft and loud sounds. The second revolution stemmed from the introduction of digital signal processing, which allows better programmability and more sophisticated algorithms. The third revolution in hearing aids is wireless, which allows seamless connectivity between a pair of hearing aids and with more and more external devices. Each revolution has fundamentally transformed hearing aids and pushed the entire industry forward significantly. Machine learning has received significant attention in recent years and has been applied in many other industries, e.g., robotics, speech recognition, genetics, and crowdsourcing. We argue that the next revolution in hearing aids is machine intelligence. In fact, this revolution is already quietly happening. We will review the development in at least three major areas: applications of machine learning in speech enhancement; applications of machine learning in individualization and customization of signal processing algorithms; applications of machine learning in improving the efficiency and effectiveness of clinical tests. With the advent of the internet of things, the above developments will accelerate. This revolution will bring patient satisfactions to a new level that has never been seen before.

  11. The dual Green Revolutions in South Korea: reforestation and agricultural revolution under the authoritarian regime.

    Science.gov (United States)

    Moon, Manyong

    2012-01-01

    In South Korea, the Green Revolution has been commonly understood as the development and dissemination of new rice varieties ('Tongil' rice) and the rapid increase of rice yield in the 1970s. However, revolutionary success in agriculture was not the only green revolution South Korea experienced; another green revolution lay in the success of reforestation projects. In the 1970s, South Korea's forest greening was closely related to its agricultural revolution in several ways. Therefore, South Korea's Green Revolution was an intrinsically linked double feature of agriculture and forestry. This two-pronged revolution was initiated by scientific research - yet accomplished by the strong administrative mobilization of President Park Chung Hee's regime. The process of setting goals and meeting them through a military-like strategy in a short time was made possible under the authoritarian regime, known as 'Yushin', though the administration failed to fully acknowledge scientific expertise in the process of pushing to achieve goals.

  14. Renewable energy adoption in an ageing population: Heterogeneity in preferences for micro-generation technology adoption

    International Nuclear Information System (INIS)

    Willis, Ken; Scarpa, Riccardo; Gilroy, Rose; Hamza, Neveen

    2011-01-01

    Many countries are endeavouring to supply more of their energy from renewable resources. Such countries are also experiencing an aging population with a greater proportion of people aged ≥65 years. This demographic shift may reduce the uptake of renewable energy, if older person households are less inclined to accept change and adopt new technologies. This paper assesses whether such households have different behavioural responses to energy efficiency compared to the rest of society and investigates whether micro-generation renewable energy technologies are less likely to be adopted by these households. It uses conditional logit and mixed logit models to investigate the impact of age of household on primary heating adoption, and also to assess the impact of older households on the installation of discretionary micro-generation technologies (solar thermal, solar voltaic, and wind power) to supplement existing heating and lighting systems. Results indicate that primary heating choice is not affected but that older person households are less inclined to adopt micro-generation technologies. - Highlights: → Heterogeneity exists in decisions on micro-generation technology installation. → Older person households are less inclined to adopt micro-generation technologies. → Micro-generation technologies fail a social cost-benefit analysis test.

  15. Technological Health Intervention in Population Aging to Assist People to Work Smarter not Harder: Qualitative Study

    2018-01-01

    Background Technology-based health care has been promoted as an effective tool to enable clinicians to work smarter. However, some health stakeholders believe technology will compel users to work harder by creating extra work. Objective The objective of this study was to investigate how and why electronic health (eHealth) has been applied in Taiwan and to suggest implications that may inspire other countries facing similar challenges. Methods A qualitative methodology was adopted to obtain insightful inputs from deeper probing. Taiwan was selected as a typical case study, given its aging population, advanced technology, and comprehensive health care system. This study investigated 38 stakeholders in the health care ecosystem through in-depth interviews and focus groups, which provides an open, flexible, and enlightening way to study complex, dynamic, and interactive situations through informal conversation or a more structured, directed discussion. Results First, respondents indicated that the use of technology can enable seamless patient care and clinical benefits such as flexibility in time management.

  16. Islamic Revolution: a Civilization-building Revolution; Iranian University:

    Directory of Open Access Journals (Sweden)

    Mohammad Baqer Khorramshad

    2009-08-01

    Full Text Available Islamic Revolution and the consequent Islamic state in Iran have revived Iranian-Islamic civilization’s discourse in a modern form which is rooted in both Iranian and Islamic ancient civilizations. Post-revolutionary Iran, as an obviously determinant country in this civilizational field, which has developed the civilization in the modern era, necessarily has to think and act civilizationally in order to resist western Humanist and Materialist affects. Academy is the place within which knowledge, as clearly one of the most important foundations of civilization-building, is produced. Civilization-building is the horizon toward which Iranian Universities should orient themselves. Academy is the canon of science, knowledge, and culture, and therefore plays an affective role in the formation, development and flourishing of a civilization; and it could be said that University is the foundation on which civilization is built. In other words, University in the modern era is not only the site of education and research, but also as an epistemological basis, participates in the process of culture and civilization-building; the matter which this study attempts to elaborate. Thus, we attempt to explain and define the necessary tools and indicators in the process.

  17. EDITORIAL: Permanent revolution - or evolution?

    Science.gov (United States)

    Dobson, Ken

    1998-03-01

    Honorary Editor It was that temporary Bolshevik Leon Trotsky who developed the principle of `permanent revolution', a principle that perhaps characterizes the recent history of education in (south) Britain more than does, say, principles traditionally associated with the Conservative or Labour parties. As this editorial is being written, changes are being made to primary school education, and the long-awaited details of the post-Dearing reorganizing of post-16 education are yet to hit the overful bookshelves and filing cabinets of school heads and examination board officials. But something unique has happened recently which might have surprised even Trotsky. The Secretary of State for Education has set up targets for primary school pupils' attainment and threatened (or promised) to resign if they are not met within the lifetime of our newly elected parliament. Of course, if Mr Blunkett is still in a position to resign at that stage he will have been the longest serving Secretary of State since time immemorial. But we should not carp: this is truly a revolutionary idea. Not the promise to resign - although this idea is not so fashionable now as it once was. The revolutionary idea is that a major change to an educational process is actually being made that carries with it a predicted and testable outcome. By contrast, when school physics was refreshed a generation ago by the introduction of Nuffield courses at both pre- and post-16 stages, no `targets' were set. I and many other physics teachers certainly preferred teaching these to teaching their predecessor syllabuses, and might even dare to assert that the pupils liked them too. But we still don't really know whether or not they learned more - or even better - physics. Very little happened as far as the outside world was concerned: the usual fraction of students gave up physics at the usual ages, and those who were examined didn't really get a better reward for their more up-to-date and more enjoyably learned

    The Ptolemaic system of the universe, with the earth at the center, had held sway since antiquity as authoritative in philosophy, science, and church teaching. Following his observations of the heavenly bodies, Nicolaus Copernicus (1473-1543) abandoned the geocentric system for a heliocentric model, with the sun at the center. His remarkable work, On the Revolutions of Heavenly Spheres, stands as one of the greatest intellectual revolutions of all time, and profoundly influenced, among others, Galileo and Sir Isaac Newton.

    More than two billion people on the planet do not have access to a reliable supply of electricity, even as greenhouse gas emissions are to approach zero in the long term. It is urgent to invent an energy system by drawing on current trends in technology and galvanizing political and industrial actors. The digital revolution is a tool for accelerating the energy revolution, a catalyst for changes in the energy sector. In 2016, Engie underwent a thoroughgoing transformation in order to become the world leader in the energy revolution. Digital technology lies at the core of this transformation. It provides powerful leverage for cementing relations between the Engie Group and its stakeholders, making the group more operationally efficient, developing new business activities and improving agility

    Phenotypes have gained increased notoriety in the clinical and biological domain owing to their application in numerous areas such as the discovery of disease genes and drug targets, phylogenetics and pharmacogenomics. Phenotypes, defined as observable characteristics of organisms, can be seen as one of the bridges that lead to a translation of experimental findings into clinical applications and thereby support 'bench to bedside' efforts. However, to build this translational bridge, a common and universal understanding of phenotypes is required that goes beyond domain-specific definitions. To achieve this ambitious goal, a digital revolution is ongoing that enables the encoding of data in computer-readable formats and the data storage in specialized repositories, ready for integration, enabling translational research. While phenome research is an ongoing endeavor, the true potential hidden in the currently available data still needs to be unlocked, offering exciting opportunities for the forthcoming years. Here, we provide insights into the state-of-the-art in digital phenotyping, by means of representing, acquiring and analyzing phenotype data. In addition, we provide visions of this field for future research work that could enable better applications of phenotype data. © The Author 2015. Published by Oxford University Press.

  7. Laparoscopic revolution in bariatric surgery.

    Science.gov (United States)

    Sundbom, Magnus

    2014-11-07

    The history of bariatric surgery is investigational. Dedicated surgeons have continuously sought for an ideal procedure to relieve morbidly obese patients from their burden of comorbid conditions, reduced life expectancy and low quality of life. The ideal procedure must have low complication risk, both in short- and long term, as well as minimal impact on daily life. The revolution of laparoscopic techniques in bariatric surgery is described in this summary. Advances in minimal invasive techniques have contributed to reduced operative time, length of stay, and complications. The development in bariatric surgery has been exceptional, resulting in a dramatic increase of the number of procedures performed world wide during the last decades. Although, a complex bariatric procedure can be performed with operative mortality no greater than cholecystectomy, specific procedure-related complications and other drawbacks must be taken into account. The evolution of laparoscopy will be the legacy of the 21(st) century and at present, day-care surgery and further reduction of the operative trauma is in focus. The impressive effects on comorbid conditions have prompted the adoption of minimal invasive bariatric procedures into the field of metabolic surgery.

  8. The Science of Structural Revolutions

    Directory of Open Access Journals (Sweden)

    William P. Graf

    2009-06-01

    Full Text Available A perspective on the very human process by which scientific paradigms change can help point the path forward in any science, or in an applied science, such as Structural Engineering. Understanding this process of change, we can examine earthquake engineering, seismic building codes and theories of structural engineering for earthquake loads. When we take this perspective, we recognize that Structural Engineering for earthquake resistance is in the midst of a number of revolutions, from paradigms embodied in current building codes in which earthquake demands are associated with forces, to a new paradigm in which earthquake demands are re-envisioned as resulting from structural displacements or drift. The new paradigm is embodied in the current national standard for the seismic rehabilitation of existing structures, ASCE 41 [2] and the emerging standards for performance-based earthquake engineering (PBEE. Associated with this is the shift from design oriented towards life-safety to design for a range of performance objectives, such as life-safety, damage reduction, or immediate occupancy. With this perspective, we further recognize deficiencies in research and development. We have failed to systematically use the experimental and computational tools we possess to fill in the gaps of scientific knowledge. We have not developed and deployed appropriate frameworks to collect and share ideas and results. As one example, the formulation of performance-based codes now outstrips the knowledge-base needed to ensure that structures designed by the new tools will meet their performance objectives.

    2010-01-12

    There is an intrinsic link between the challenge we face to ensure food security through the twenty-first century and other global issues, most notably climate change, population growth and the need to sustainably manage the world's rapidly growing demand for energy and water. Our progress in reducing global poverty and achieving the Millennium Development Goals will be determined to a great extent by how coherently these long-term challenges are tackled. A key question is whether we can feed a future nine billion people equitably, healthily and sustainably. Science and technology can make a major contribution, by providing practical solutions. Securing this contribution requires that high priority be attached both to research and to facilitating the real world deployment of existing and emergent technologies. Put simply, we need a new, 'greener revolution'. Important areas for focus include: crop improvement; smarter use of water and fertilizers; new pesticides and their effective management to avoid resistance problems; introduction of novel non-chemical approaches to crop protection; reduction of post-harvest losses; and more sustainable livestock and marine production. Techniques and technologies from many disciplines, ranging from biotechnology and engineering to newer fields such as nanotechnology, will be needed.

    For four years the National Science Foundation (NSF)-sponsored TeXas Earth and Space Science (TXESS) Revolution professional development program has helped teachers build a solid foundation in the geosciences through guided inquiry activities and lectures delivered by science experts. The professional development program comprises eight professional development academies and two summer institutes. Climate literacy has been a cross-cutting theme throughout the series of academies and institutes. Although we present a special emphasis on climate literacy in the 7th academy on Climate Change, the 8th academy on Humans at the Helm and the 2nd summer institute module on climate mitigation technology, activities related to climate literacy are woven into each academy. Examples of climate as a cross-cutting theme include a module on water and drought, including research on climate change through the analysis of deep-sea cores, and the effects on the Mayan population. Our distinguished lecturers bring in climate literacy as part of their presentations and programs: our Poking Holes into the Planet and Team Science professional development academy included two distinguished lecturers who brought current research results and educational materials from the ANDRILL (Antarctic Geological Drilling) program and the Integrated Ocean Drilling Program. Our Earth as a Habitable Planet professional development academy featured an activity on corals that used data to explore how higher than normal sea surface temperatures contribute to coral bleaching events. TXESS Revolution also works with our teachers to link them with other opportunities aligned with our professional development goals. With our assistance, one of our TXESS Revolution teachers sailed as part of the science team on Integrated Ocean Drilling Program expedition 317 to investigate sea level fluctuations in the Canterbury Basin offshore New Zealand, creating various resources (e.g., podcasts, blogs) to multiply the

    Technology-based health care has been promoted as an effective tool to enable clinicians to work smarter. However, some health stakeholders believe technology will compel users to work harder by creating extra work. The objective of this study was to investigate how and why electronic health (eHealth) has been applied in Taiwan and to suggest implications that may inspire other countries facing similar challenges. A qualitative methodology was adopted to obtain insightful inputs from deeper probing. Taiwan was selected as a typical case study, given its aging population, advanced technology, and comprehensive health care system. This study investigated 38 stakeholders in the health care ecosystem through in-depth interviews and focus groups, which provides an open, flexible, and enlightening way to study complex, dynamic, and interactive situations through informal conversation or a more structured, directed discussion. First, respondents indicated that the use of technology can enable seamless patient care and clinical benefits such as flexibility in time management. Second, the results suggested that a leader's vision, authority, and management skills might influence success in health care innovation. Finally, the results implied that both internal and external organizational governance are highly relevant for implementing technology-based innovation in health care. This study provided Taiwanese perspectives on how to intelligently use technology to benefit health care and debated the perception that technology prevents human interaction between clinicians and patients. ©Sonia Chien-I Chen.

    Full Text Available The rapid pace of technological developments played a key role in the previous industrial revolutions. However, the fourth industrial revolution (Industry 4.0 and its embedded technology diffusion progress is expected to grow exponentially in terms of technical change and socioeconomic impact. Therefore, coping with such transformation require a holistic approach that encompasses innovative and sustainable system solutions and not just technological ones. In this article, we propose a framework that can facilitate the interaction between technological and social innovation to continuously come up with proactive, and hence timely, sustainable strategies. These strategies can leverage economic rewards, enrich society at large, and protect the environment. The new forthcoming opportunities that will be generated through the next industrial wave are gigantic at all levels. However, the readiness for such revolutionary conversion require coupling the forces of technological innovation and social innovation under the sustainability umbrella.

    The 21st Century will be fundamentally different from the previous one in all aspects of the human life. The world is now facing unprecedented challenges that will determine the fate of the human race as a whole. Our tiny planet is too small to shoulder the weight of six and a half billion energy-needy people and it is too vulnerable to afford violent and confrontational approaches as was the case in the past 20th century. It is also a fact that science opened new horizons before us. Digital Revolution inaugurated a new era in human history. Technology offers tremendous opportunities to overcome new and inherited problems. Sadly, the family of nations is ill-equipped for handling these challenges because the organizational structure of the world society is archaic and inoperative. Or, we live in a geo strategic environment pregnant with dangerous crisis of global significance. Furthermore, the good old days when scientists were heeded respectfully as reliable guides and when scientific facts were accepted as 'veritas' are over. Solid scientific arguments are perceived as cover up stories to defend financial interests of multinational companies. Similarly, confidence in politicians is at its lowest level in several countries. At the center of this puzzle lies a frenetic quest for cleaner, cheaper and more secure energy sources. In such circumstances, the best remedies which may be created by the brightest minds of the world will be tributary to the 'goodwill' of politicians. Or, politicians are under the overwhelming pressure of their respective public opinions who may act according to emotional factors or advices from religion, gossip or ideology. Consequently, 'Societal Issues' will be 'the decisive' factor in shaping the future of 'Emerging Nuclear Energy Systems' as well as nonnuclear technologies. This paper will attempt to identify major elements of this global equation from a political standpoint. One also has to take into account a group of new and powerful

I examine Senegalese conversion narratives and the central role played by the Iranian Revolution, contextualizing life stories (trans)nationally in Senegal's political economy and global networks with Iran and Lebanon. Converts localize foreign religious ideologies into a 'national' Islam through the discourse that Shi`i education can bring peace and economic development to Senegal. Senegalese Shi`a perceive that proselytizing, media technologies, and Muslim networking can lead to social, cultural and perhaps even political change through translating the Iranian Revolution into a non-violent reform movement.

  1. Implications of the sexual revolution.

    Science.gov (United States)

    Dominian, J

    1982-06-01

    2 sexual revolutions have occurred in the last 30 years: an immense increase in knowledge of sexual matters and the accompanying expansion of providing therapy for sexual disorders; and a radical change in sexual attitudes and behavior. Discussion focuses on the ethical implications of these changes. The standards of sexual morality in this society are derived from the Judeo Christian tradition. In the beginning of Genesis there are 2 passages which are fundamental for the origin and understanding of traditional morality. In these 2 passages sexuality is first linked with establishing a man woman permanent relationship and secondly as the means of giving rise to new life. The origins of the standard Christian mortality about sex was that it was good for procreation and procreation was confined to marriage. All sexual activity before marriage and outside marriage was condemned; fornication and adultery were both wrong. This tradition of confining sex to marriage for the purpose of procreation has continued to the present when it has been widely challenged and contravened. The advent of birth control has had a pronounced effect. For the 1st time sexual intercourse and procreation are totally and effectively separated. As a result sexual activity in previously forbidden situations is now rampant. There exists an extensive preoccupation with sex. Many lavish praise on love making, yet it all depends on what is meant by lovemaking. There are at least 3 ways of understanding lovemaking: solitary sex; transient sex between a couple; and sexual intercourse within marriage. There are single people who extol solitary sex, people who insist that they do not need other people in their life. Masturbation has a place in the life of adolescents and may reassert itself when men and women are separated, but the pleasure of mutual involvement is so much greater that masturbation readily yields to heterosexual activity in the majority of cases and homosexual activity in a small

    Digital technology (DT) plays an increasingly important role in the health sector. This study explores how national public health associations (PHAs) use DT to achieve their mandate. The World Federation of Public Health Associations canvassed and conducted a semi-structured interview with its national public health association members about their use of DT, the challenges they encounter in using it, and their experiences and thoughts as to how to assess its impact, both organizationally as well as on population health and health equity. The study found that digital technology plays an important role in some PHAs, principally those in higher income countries. PHAs want to broaden their use within PHAs and to assess how DT enables PHAs to achieve their organizational mandates and goals, including improved public health and health equity.

    Mandler, George

    2002-01-01

    The well documented cognitive "revolution" was, to a large extent, an evolving return to attitudes and trends that were present prior to the advent of behaviorism and that were alive and well outside of the United States, where behaviorism had not developed any coherent support. The behaviorism of the 1920 to 1950 period was replaced because it was unable to address central issues in human psychology, a failure that was inherent in part in J. B. Watson's founding manifesto with its insistence on the seamless continuity of human and nonhuman animal behavior. The "revolution" was often slow and piecemeal, as illustrated by four conferences held between 1955 and 1966 in the field of memory. With the realization that different approaches and concepts were needed to address a psychology of the human, developments in German, British, and Francophone psychology provided some of the fuel of the "revolution."

  5. Hacking the quantum revolution: 1925-1975

    Science.gov (United States)

    Schweber, Silvan S.

    2015-01-01

    I argue that the quantum revolution should be seen as an Ian Hacking type of scientific revolution: a profound, longue durée, multidisciplinary process of transforming our understanding of physical nature, with deep-rooted social components from the start. The "revolution" exhibits a characteristic style of reasoning - the hierarchization of physical nature - and developed and uses a specific language - quantum field theory (QFT). It is by virtue of that language that the quantum theory has achieved some of its deepest insights into the description of the dynamics of the physical world. However, the meaning of what a quantum field theory is and what it describes has deeply altered, and one now speaks of "effective" quantum field theories. Interpreting all present day quantum field theories as but "effective" field theories sheds additional light on Phillip Anderson's assertion that "More is different". This important element is addressed in the last part of the paper.

    Following the Islamic Revolution of 1979 in Iran, the trend of migration of physicians from the country continued. The total number of Iranian physicians migrated to the United States (US) increased from 1625 before revolution in 1974, to 5045 in 2010, thirty years post-revolution. The percentage of medical graduates migrating to the US, in the same period dropped from 15% to 5%. The reasons for this drop were restrictions imposed, along with creation of good postgraduate residency and fellowship programs in Iran. Following the revolution, the number of medical schools increased from 13 to 48. Despite all the restrictions and impediments for post-revolution medical graduates, over 500 medical graduates from newly established medical schools found their ways into the healthcare system of the US.     In spite of all hardships of eight years of imposed war, and 30 years of the US sanctions, Iran has been able to maintain good progress in its healthcare, education, and research in medicine and other branches of science and technology.

Rather than a cause for celebration, this delay should encourage reflection on the role of research in society. Why is it so difficult to realize sustainability in practice? The answer lies in the fact that universities and research centres persist with 19th century methods of data gathering, scholarly analysis, and journal articles. Today’s world needs science in real-time, whether to detect drought, confront Ebola, or assist refugees. Research needs to work faster and embrace 21st century practices including data science, open access, and infographics.A silent revolution is occurring in the ways of organizing and conducting research, enabled by new technology and encouraging work that tackles the key challenges facing society. A variety of new arrangements have come into existence that promote international collaboration, including Horizon 2020 with its emphasis on societal challenges, the Bill & Melinda Gates Foundation which has inspired a family of grand challenges funds on health and development, and the Future Earth joint program of research for global sustainability. These arrangements not only control billions of dollars in research funding, they also influence the strategies of national research councils and international organizations. The result is no less than a transformation in the incentives that reward how researchers invest their time and effort.Why is a revolution needed? Within research, substantial growth in knowledge production coincided with fragmentation among disciplines. One can easily find expertise and publications in soil science or agronomy, yet integrated efforts on food security and climate adaptation remain scarce. Beyond research, society remains largely uninformed, as academics avoid engaging in public

  10. The livestock revolution--a global veterinary mission.

    Steinfeld, Henning

    2004-10-28

    Increasing population, urbanisation and disposable incomes in developing countries are fuelling a strong growth in demand for animal food products, which in turn will have a strong impact on the location and organisation of global livestock production. Changes in the latter will in turn strongly impinge on animal and human health, the livelihoods of the poor and the environment. The consequences of these trends, termed the 'livestock revolution', are expected to dramatically change the face of animal agriculture in coming decades, including a major increase in the developing countries' share in world livestock production and consumption; a gradual substitution of cereals and other basic foods with meat and milk in the developing countries' diets; a change from multiple production objectives to more specialised intensive meat, milk and egg production within an integrated global food and feed market; a shift to more industrial production and processing; rising use of cereal-based animal feeds; and greater stress on fragile extensive pastoral areas and more pressure on land in areas with very high population densities and close to urban centres. Henning Steinfeld, an agricultural economist from the Food and Agriculture Organization of the United Nations, reviews here trends associated with the 'Livestock Revolution' and predicted implications for animal health. The presentation was given in a plenary session at the 19th International Conference of the World Association for the Advancement of Veterinary Parasitology (WAAVP) held in New Orleans, Louisiana, USA during 10-14 August 2003.

    Among the theoreticians dealing with the development of democracy a woman can seldom be found. However, that the influence of the women’s rights issue on the democratic revolution is by no means a minor one, but quite the contrary, demonstrates Mary Wollstonecraft’s essay »Vindication of the Rights of Woman«. In his considerations regarding the relation between the women’s rights issue and the democratic revolution, Mastnak relies upon this very book and its interpretations. In contrast to so...

    Originally published in English in 1973. This volume traces the development of the revolution which so drastically altered man's view of the universe in the sixteenth and seventeenth centuries. The ""astronomical revolution"" was accomplished in three stages, each linked with the work of one man. With Copernicus, the sun became the centre of the universe. With Kepler, celestial dynamics replaced the kinematics of circles and spheres used by Copernicus. With Borelli the unification of celestial and terrestrial physics was completed by abandonment of the circle in favour the straight line to inf

    Some of the most important things in life are taken for granted, and nowhere is this truer than with light. In this article, we will look at some important milestones marking light's path from human evolution to sustainable revolution, challenges facing the modern lighting industry as well as the world we live in, and what the future promises. In a sense, a new revolution is at hand. It would be hard to overestimate the fundamental importance of light as it shapes virtually everything we sense and experience.

  14. Energy and the English Industrial Revolution.

    Science.gov (United States)

    Wrigley, E A

    2013-03-13

    Societies before the Industrial Revolution were dependent on the annual cycle of plant photosynthesis for both heat and mechanical energy. The quantity of energy available each year was therefore limited, and economic growth was necessarily constrained. In the Industrial Revolution, energy usage increased massively and output rose accordingly. The energy source continued to be plant photosynthesis, but accumulated over a geological age in the form of coal. This poses a problem for the future. Fossil fuels are a depleting stock, whereas in pre-industrial time the energy source, though limited, was renewed each year.

    Post-green revolution advances made in biotechnology paved the way of cultivating the high-yielding, stress and disease resistant genetically modified (GM) varieties of wheat, rice, maize cotton and several other crops. The recent rapid commercialization of the genetically modified crops in Asia, Americas and Australia indicates the potentiality of this new technology. GM crops give higher yields and are rich in nutritional values containing vitamins and minerals and can thus can help to alleviate hunger and malnutrition of the growing population in the under developed and developing countries. It could also be possible to develop more biotic and abiotic stress resistant genotypes in these crops where it was difficult to develop due to the unavailability of genes of resistance in the crossing germplasms. However, further research and investigations are needed to popularize the cultivation of these crops in different parts of the world. This review provides an insight of the impact of GM crops on contemporary agriculture across the past few decades, traces its' history across time, highlights new achievements and breakthroughs and discusses the future implication of this powerful technology in the coming few decades.

  20. Impact of the Cryogen Free Revolution on Neutron Scattering Laboratories

    Science.gov (United States)

    Kirichek, Oleg

    A global shortage of helium gas can seriously jeopardise the scientific programmes of neutron scattering laboratories due to the use of cryogenic sample environment in the majority of the neutron scattering experiments. Recently developed cryogen-free technology allows a significant reduction or even a complete elimination of liquid helium consumption. Here we review the impact of the cryogen-free revolution on cryogenic equipment used at large neutron facilities, such as cryostats, dilution refrigerators, superconducting magnets and other cryogenic systems. Particular attention is given to the newly developed superconducting magnets for neutron diffraction and spectroscopy experiments. Use of the cryogen-free approach, as well as cutting-edge superconducting magnet technology and advanced neutron optics allows researcher to achieve extraordinary performance in their experiments, opening up new opportunities in neutron scattering research.

    Digital technology is increasingly used in humanitarian action and promises to improve the health and social well-being of populations affected by both acute and protracted crises. We set out to (1) review the current landscape of digital technologies used by humanitarian actors and affected populations, (2) examine their impact on health and well-being of affected populations, and (3) consider the opportunities for and challenges faced by users of these technologies. Through a systematic search of academic databases and reports, we identified 50 digital technologies used by humanitarian actors, and/or populations affected by crises. We organized them according to the stage of the humanitarian cycle that they were used in, and the health outcomes or determinants of health they affected. Digital technologies were found to facilitate communication, coordination, and collection and analysis of data, enabling timely responses in humanitarian contexts. A lack of evaluation of these technologies, a paternalistic approach to their development, and issues of privacy and equity constituted major challenges. We highlight the need to create a space for dialogue between technology designers and populations affected by humanitarian crises.

  2. New technology and illness self-management: Potential relevance for resource-poor populations in Asia.

    Science.gov (United States)

    Lucas, Henry

    2015-11-01

    Advances in technology have made it possible for many standard diagnostic and health monitoring procedures, traditionally carried out by qualified personnel within medical facilities, to be reliably undertaken by patients or carers in their own homes with a minimum of basic training. There has also been a dramatic increase in the number and diversity of both sources of information on health issues and the possibilities for sharing information and experiences over ICT-based social networks. It has been suggested that these developments have the potential to 'empower' patients, reducing their dependence on providers and possibly improving their quality of care by increasing the volume and timeliness of diagnostic data and encouraging active self-management of their condition, for example through lifestyle changes. Perhaps more significantly, it is also seen by many economies with ageing populations as a way to contain high and ever rising healthcare costs. It has also been suggested that a move to greater self-management supported by expert networks and smart phone technology could improve the treatment of many millions of patients with chronic diseases in low and middle income economies that are also confronting the potential cost implications of epidemiological and demographic transitions, combined with the higher expectations of a more educated and knowledgeable population. There is now limited evidence that some fairly basic e- and mHealth interventions, for example in the areas of MNCH, malaria and HIV/AIDS can have a positive impact, even in resource-poor contexts. The aim here is to explore the extent to which further investment in technology could play a role in the development of an effective and affordable health sector strategy for at least some developing economies. It is suggested that the effectiveness of the approach may be highly dependent on the specific health conditions addressed, the nature of existing health systems and the overall socio

    estimates of the actual working year, we find two ‘industrious' revolutions among rural workers; both, however, are attributable to economic hardship, and we detect no signs of a consumer revolution. For urban labourers, by contrast, a growing gap between their actual working year and the work  required......It is conventionally assumed that the pre-modern working year was fixed and that consumption varied with changes in wages and prices. This is challenged by the twin theories of the ‘industrious' revolution and the consumer revolution, positing a longer working year as people earned surplus money...... to buy novel goods. In this study, we turn the conventional view on its head, fixing consumption rather than labour input. Specifically, we use a basket of basic consumption goods and compute the working year of rural and urban day labourers required to achieve that. By comparing with independent...

  9. The Mexican Revolution and health care or the health of the Mexican Revolution.

    Science.gov (United States)

    Horn, J J

    1985-01-01

    Despite a victorious social revolution, a self-proclaimed "revolutionary" government, and a significant post-war economic growth, Mexico has not achieved a just or equitable social system. The Mexican Revolution led to the emergence of a new bureaucratic class whose "trickle-down" development strategy sacrificed social welfare to capital accumulation. Mexican morbidity and mortality patterns resemble those of more impoverished developing nations without revolutionary experience. The patterns of health care in Mexico reflect inequities and contradictions in the society and economy at large and flow from the erosion of the egalitarian aims of the revolution concomitant with the expansion of capitalism and the concentration of the benefits of "modernization" in the hands of privileged elites. Mexico's health problems are symptomatic of a general socio-economic malaise which questions the legitimacy of the Revolution.

  12. Dissent, revolution and liberty beyond Earth

    CERN Document Server

    2016-01-01

    This volume provides an in-depth discussion on the central question – how can people express and survive dissent and disagreement in confined habitats in space? The discussion is an important one because it could be that the systems of inter-dependence required to survive in space are so strong that dissent becomes impossible. John Locke originally said that people have a right to use revolution to overthrow a despotic regime. But if revolution causes violence and damage that causes depressurisation with the risk of killing many people, is it even permissible to have a revolution? How then are people to express their liberty or dissatisfaction with their rulers? The emergence of structures of dissent and disagreement is an essential part of the construction of a framework of liberty in space (revolution is just the extreme example) and thus the topic deserves in-depth and immediate attention. Even today, the way in which we assemble organisations and corporations for the government and private exploration o...

    There is considerable potential for mobile technologies to empower pediatric patients and families by improving their communication with health professionals. National surveys suggest minority parents frequently communicate via mobile technology, but it is uncertain how amenable they are to receiving health care information in this format. Although the low cost and far reach characteristics of mobile health (mHealth) technology makes it advantageous for communication with minority parents, data on acceptance are needed. The objective of the study was to determine utilization of mobile and Internet technology by African American parents in an urban, underserved population, and to assess their interest in receiving health information via text messaging or other technologies (eg, social media and the Internet). A survey was administered to parents of children aged 1-12 years covered by public insurance receiving care at 3 pediatric primary care centers in Washington, DC. The African American sample (N=302) was composed of primarily single (75.8%, 229/302) mothers. Almost half had more than a high school education (47.7%, 144/302) and incomes above US $25,000 per year (43.0%, 130/302). Most (97.0%, 293/302) reported owning a cell phone, of which 91.1% (275/302) used it to text and 78.5% (237/302) used it to access the Internet. Most had service plans with unlimited text and data, but 26.5% (80/302) experienced service interruptions in the previous year. Home Internet access was more prevalent among those with higher income (86.2%, 112/130), but it was still relatively pervasive among lower income families (66.9%, 83/124). In adjusted logistic regression models, African American mothers with income greater than US $25,000 annually were 4 times as likely to own a tablet computer than their lower income counterparts. Of the participants, 80.8% (244/302) used social networking, primarily Facebook, and 74.2% (224/302) were interested in joining a social networking group

    Full Text Available The few studies on renewal of Eucalyptus spp populations done in Brazil consider constant technology. This is done this way for facilitating the modeling of how variables affect this activity, such as income, costs, rates of discount and yield. The reason for not considering the gains earned through technological progress is the lack of a specific dynamic model. This study was carried out aiming to get to know the forest rotation with values from the sixties (beginning of tax exemption programme and current values (nineties aiming to obtain wood for cellulose and charcoal production; to determine the moment of substitution of a population which presents the same yield and the same cost structure through time as well as to determine how many cuttings should be done until the final cycle; to determine how many cuttings should be done until substitution (substitution chain; to verify the sensitivity of the substitution time to variations in the discount rates, wood prices, yield, land costs, harvesting costs and coppice yield. The results were tested in a case study, employing the Gompertz Function to determine the population yield. The Current Net Value Method was used as a crieterion of economic decision. It has been concluded that: The forest rotation to produce charcoal in the sixties was at 13 years of age; the current rotation is at 7 years of age; the final cycle allows up to 13 cuttings, but considering the possibility of land leasing, the best alternative is to conduce the sproutings up to the third cutting; an increase in factors such as discount rates, wood prices and yield caused reduction of the cutting age; increase in land costs did not affect the cutting ages; increase in the logging cost increased the cutting ages; the substitution of population now a days happens after 3 cuttings, while in the sixties it happened after 2 cuttings due to the lesser loss; an increase in factors such as discount rates, wood prices, logging costs and

    2017-01-01

    Full Text Available On July 9th, 1925, a coup d’état overthrew the Ecuadorian government of the president Gonzalo S. Córdova. The Military Junta chose the new president, Dr. Isidro Ayora, who founded the Central Bank of Ecuador in 1927. The majority of historians emphasize the patriotic spirit of the military forces in order to eliminate the influence of private banks. Nonetheless, there is a less popular view of the Julian Revolution, which understands the coup d’état, and the foundation of the Central Bank of Ecuador, as the result of struggles between bankers due to controversies around currency emissions. The arguments behind the Julian Revolution were based on some economic facts. Even though real GDP did not decrease in any year from 1913 to 1927, there was a generalized perception of a critical economy due to the constant fluctuation in prices, the increasing of fiscal deficit, and the reduction of revenues from the trade balance. The economic crisis was a common factor in the urban areas, which represented less than half percent of the total population.

    Providing Healthcare to rural population has been a challenge to the medical service providers especially in developing countries. For this to be effective, scalable and sustainable, certain strategic decisions have to be taken during the planning phase. Also, there is a big gap between the services available and the availability of doctors and medical resources in rural areas. Use of Information Technology can aid this deficiency to a good extent. In this paper, a mobile application has been developed to gather data from the field. A cloud based interface has been developed to store the data in the cloud for effective usage and management of the data. A decision tree based solution developed in this paper helps in diagnosing a patient based on his health parameters. Interactive geospatial maps have been developed to provide effective data visualization facility. This will help both the user community as well as decision makers to carry out long term strategy planning.

    While technology is a major driver of many of society's comforts, conveniences, and advances, it has been responsible, in a significant way, for engineering regular physical activity and a number of other positive health behaviors out of people's daily lives. A key question concerns how to harness information and communication technologies (ICT) to bring about positive changes in the health promotion field. One such approach involves community-engaged "citizen science," in which local residents leverage the potential of ICT to foster data-driven consensus-building and mobilization efforts that advance physical activity at the individual, social, built environment, and policy levels. The history of citizen science in the research arena is briefly described and an evidence-based method that embeds citizen science in a multi-level, multi-sectoral community-based participatory research framework for physical activity promotion is presented. Several examples of this citizen science-driven community engagement framework for promoting active lifestyles, called "Our Voice", are discussed, including pilot projects from diverse communities in the U.S. as well as internationally. The opportunities and challenges involved in leveraging citizen science activities as part of a broader population approach to promoting regular physical activity are explored. The strategic engagement of citizen scientists from socio-demographically diverse communities across the globe as both assessment as well as change agents provides a promising, potentially low-cost and scalable strategy for creating more active, healthful, and equitable neighborhoods and communities worldwide.

    The aim of the current study was to evaluate the effectiveness of three nonthermal light technologies (NUV-Vis, continuous UV, and HILP) on their ability to inactivate Escherichia coli K12 and Listeria innocua.  E. coli K12 was selected as a representative microorganism for the enterohaemorrhagic foodborne pathogen E. coli O157:H7 and L. innocua as a surrogate microorganism for the common foodborne pathogen Listeria monocytogenes, respectively. The liquid matrix used for the disinfection experiments was a liquid matrix (MRD solution). The results of the present study show that the HILP treatment inactivated both E. coli and L. innocua more rapidly and effectively than either continuous UV-C or NUV-vis treatment. With HILP at 2.5 cm from the lamp, E. coli and L. innocua populations were reduced by 3.07 and 3.77 log10 CFU/mL, respectively, after a 5 sec treatment time, and were shown to be below the limit of detection (<0.22 log10 CFU/mL) following 30 sec exposure to HILP (106.2 J/cm(2)). These studies demonstrate the bactericidal efficacy of alternative nonthermal light technologies and their potential as decontamination strategies in the food industry.

    Many health systems recovering from a massive investment in electronic health records are now faced with the prospect of maturing into accountable care organizations. This maturation includes the need to cooperate with new partners, involve substantially new data sources, require investment in additional information technology (IT) solutions, and become proficient in managing care from a new perspective. Adding to the confusion, there are hundreds of population health management (PHM) vendors with overlapping product functions. This article proposes an organized approach to investing in PHM IT. The steps include assessing the organization's business and clinical goals, establishing governance, agreeing on business requirements, evaluating the ability of current IT systems to meet those requirements, setting time lines and budgets, rationalizing current and future needs and capabilities, and installing the new systems in the context of a continuously learning organization. This article will help organizations chart their position on the population health readiness spectrum and enhance their chances for a successful transition from volume-based to value-based care.

  13. Health and the urban environment: revolutions revisited

    2009-05-15

    From cholera pandemics to smog episodes, urban development driven by narrow economic interests has shown itself to be a serious threat to human health and wellbeing. Past revolutions in sanitation and pollution control demonstrate that social movements and governance reforms can transform an urban health penalty into a health advantage. But many environmental problems have been displaced over time and space, and never truly resolved. Health concerns need once again to drive an environmental agenda – but this time it must be sustainable over the long haul, and globally equitable. With the global economic crisis raising the ante, what's needed is no less than a revolution in environmental justice that puts health, not economics, at the core of its values.

    This book is about how electronics, computing, and telecommunications have profoundly changed our lives – the way we work, live, and play. It covers a myriad of topics from the invention of the fundamental devices, and integrated circuits, through radio and television, to computers, mobile telephones and GPS. Today our lives are ruled by electronics as they control the home and computers dominate the workspace. We walk around with mobile phones and communicate by email. Electronics didn’t exist until into the twentieth century. The industrial revolution is the term usually applied to the coming of steam, railways and the factory system. In the twentieth century, it is electronics that has changed the way we gather our information, entertain ourselves, communicate and work. This book demonstrates that this is, in fact, another revolution. .

Years, in many countries of North Africa and the Middle East, called the ''Arab revolutions''. For some, these events are coincidental and spontaneous protest ''dreamers of democracy'', while for others it is a result of the planned implementation of projects for a global reorganization of the world. Besides the difference in the value perception of ''colored revolutions'', among theorists there is no agreement even on issues of their target orientation and of their relationship to democracy, social reasonableness, and especially of compatibility of goals and the methods for their realizations.

    Visual analysis of biomolecules is an integral avenue of basic and applied biological research. It has been widely carried out by tagging of nucleotides and proteins with traditional fluorophores that are limited in their application by features such as photobleaching, spectral overlaps, and operational difficulties. Quantum dots (QDs) are emerging as a superior alternative and are poised to change the world of bio-imaging and further its applications in basic and applied biology. The interdisciplinary field of nanobiotechnology is experiencing a revolution and QDs as an enabling technology have become a harbinger of this hybrid field. Within a decade, research on QDs has evolved from being a pure science subject to the one with high-end commercial applications

    2010-01-01

    The potyviruses are one of the two most speciose taxa of plant viruses. Our expanded knowledge of the breadth and depth of their diversity and its origins has depended greatly on the use of computing and the Internet in biological research and is reviewed here. We report a fully supported phylogeny based on gene sequence data for approximately half the named species. The phylogeny shows that the genus probably originated from a virus of monocotyledonous plants and that it first diverged approximately 7250 years ago in Southwest Eurasia or North Africa. The use of computer programs to better understand the structure and evolutionary trajectory of potyvirus populations is illustrated. The review concludes with recommendations for improving potyvirus nomenclature and the databasing of potyvirus information.

  1. Toward a Rethinking of the Relativity Revolution

    Science.gov (United States)

    Siegel, Daniel

    2014-03-01

    This journey in the history of physics is offered in celebration of David Cassidy's Pais Prize. The journey, undertaken in part with the community of historians of physics and in part not, starts from a conventional characterization of the relativity revolution as an abrupt transition, in 1905, from pre-Einsteinian darkness to Einsteinian light, and ends with an alternative perspective on the relativity revolution, seeing it as a process extending over 50 years, in two phases: first, the protorelativity phase, lasting from the early 1880s to 1905, and involving initial treatments of the length contraction, the mass increase, and invariance properties; second, the Einsteinian phase, beginning with his recasting of the basic theoretical framework--with the inclusion now of the time dilation and the E = mc2 relationship--and continuing with the ensuing competition between the protorelativistic and Einsteinian approaches, issuing in the final triumph of the Einsteinian approach only in the early 1930s. A proper appreciation of the character and importance of the protorelativity phase of the relativity revolution is relevant to a variety of contexts: for the teaching of relativity theory, it makes available a more concrete and pictorial approach to the relativistic effects--retaining greater (length contraction) or somewhat lesser (mass increase) validity to the present day; for the ongoing discourse on the nature of scientific revolutions, it provides a perspective on the intricacies and complexities of those occurrences, and on the elements of continuity and gradualism in even the most radical changes; and for our general understanding of historical process in the history of the sciences, it shows the importance of the broader scientific research community for even the most individual accomplishments.

  2. The Nineteenth-Century Revolution in Astronomy

    2015-08-01

    The term "revolution" in scientific contexts usually refers either to the beginnings of modern western science in the sixteenth and seventeenth centuries, or to the two great revolutions of early twentieth century physics. Comparison of what was known at the beginning of the nineteenth century with what was known at the end, however, shows that century to have been one of transformation in astronomy, and in the other sciences, that amounts to "revolution". Astronomers in 1800 knew neither the nature of the Sun nor the distances of the stars. Developments in instrumentation enabled the first determinations of stellar parallax in the 1830s, and later enabled the solar prominences to be studied outside the brief momemnts of total eclipses. The development of photography and of spectroscopy led to the birth of observational astrophysics, while the greater understanding of the nature of heat and the rise of thermodynamics made possible the first attempts to investigate the theory of stellar structure. Nothing was known in 1800 of extra-galactic objects apart from some tentative identifcations by William Herschel but, by the end of the century, the discovery of the spiral structure of some nebulae had led some to believe that these were the "island universes" about which Kant had speculated. Of course, astrophysics and cosmology would be much further developed in the twentieth century and those of us whose careers spanned the second half of that century look back on it as a "golden age" for astronomy; but the nineteenth century was undoubtedly a time of rapid transformation and can be reasonably described as as one of the periods of revolution in astronomy.

  3. Toward a microbial Neolithic revolution in buildings.

    Thaler, David S

    2016-03-29

    The Neolithic revolution--the transition of our species from hunter and gatherer to cultivator--began approximately 14,000 years ago and is essentially complete for macroscopic food. Humans remain largely pre-Neolithic in our relationship with microbes but starting with the gut we continue our hundred-year project of approaching the ability to assess and cultivate benign microbiomes in our bodies. Buildings are analogous to the body and it is time to ask what it means to cultivate benign microbiomes in our built environment. A critical distinction is that we have not found, or invented, niches in buildings where healthful microbial metabolism occurs and/or could be cultivated. Key events affecting the health and healthfulness of buildings such as a hurricane leading to a flood or a burst pipe occur only rarely and unpredictably. The cause may be transient but the effects can be long lasting and, e.g., for moisture damage, cumulative. Non-invasive "building tomography" could find moisture and "sentinel microbes" could record the integral of transient growth. "Seed" microbes are metabolically inert cells able to grow when conditions allow. All microbes and their residue present actinic molecules including immunological epitopes (molecular shapes). The fascinating hygiene and microbial biodiversity hypotheses propose that a healthy immune system requires exposure to a set of microbial epitopes that is rich in diversity. A particular conjecture is that measures of the richness of diversity derived from microbiome next-generation sequencing (NGS) can be mechanistically coupled to--rather than merely correlated with some measures of--human health. These hypotheses and conjectures inspire workers and funders but an alternative is also consequent to the first Neolithic revolution: That the genetic uniformity of contemporary foods may also decrease human exposure to molecular biodiversity in a heath-relevant manner. Understanding the consequences--including the unintended

    Axisymmetric shells of revolution are used for chemical plants, nuclear power plants, aircrafts, structures and so on, and the elucidation of their free vibration is important for the design. In this study, the axisymmetric vibration of a barrel-shaped shell was analyzed by the modified thick shell theory. The Lagrangian during one period of the vibration of a shell of revolution was determined, and from its stopping condition, the vibration equations and the boundary conditions were derived. The vibration equations were analyzed strictly by using the series solution. Moreover, the basic equations for the strain of a shell and others were based on those of Love. As the examples of numerical calculation, the natural frequency and vibration mode of the symmetrical shells of revolution fixed at both ends and supported at both ends were determined, and their characteristics were clarified. By comparing the results of this study with the results by thin shell theory, the effects of shearing deformation and rotary inertia on the natural frequency and vibration mode were clarified. The theoretical analysis and the numerical calculation are described. The effects of shearing deformation and rotary inertia on the natural frequency became larger in the higher order vibration. The vibration mode did not much change in both theories. (Kako, I.)

In addition, evidence-based arguments are included to provide validity of some affirmations. The first section argues that the social sciences are the daughters and an essential part of democracy. A few historical arguments about the way in which the dominant classes have slowed down the scientific progress and the development of people that make it possible. In the second section, it is analyzed the opposition of feudal universities to this unstoppable beginning of what could be called the scientific and democratic revolution. At the same time, we deal with its ambivalent character requiring to be supported and to be criticized so that it can be improved. In the third section, we expound the way in which this progress has provide some conditions that makes it possible to overcome the strong gender-based violence happening in our institutions of higher education and makes it also possible that women who were persecuted are now transforming our universities. Influences and criticism to our university feudalism, made by social movements such as the named 'Spanish Revolution', appear in the fourth section. In the fifth and last section, we offer a proposal to promote the scientific, democratic, and revolutionary approach of the university.

    2011-01-01

    While the Green Revolution has been successful in some regions like South and East Asia, it could hardly address any achievement in Sub-Saharan Africa (SSA). This paper tries to draw a picture on lessons learned from the failures of this revolution that should be taken into account before implementing the so-called Gene Revolution in the SSA region. After scrutinizing the failures and the pros and cons of GM crops in the region, the paper introduces some potentials for improving the malnutrition situation in SSA through launching a successful GM technology. However, it remains doubtful whether this technology can improve the situation of small-scale farmers as long as they receive no financial support from their national governments. Therefore, before any intervention, the socio-economic and environmental impacts of GM technology need to be carefully addressed in the framework of a series of risk assessment studies. Besides, some sort of multi-stakeholder dialog (from small-scale farmers to consumers) involving public-private sector and non-governmental organizations should be heated up at both national and regional levels with regard to the myths and truths of this technology.

    Full Text Available The differences between the decentralized model of the British financial market from the centralized French (continental model emerged after the financial revolution of 1688 in England, which lasted until the end of the XVII century and had an impact on public and private finance. Due to the captivity of the French Huguenots shortly before the "Glorious Revolution" in England, new technologies appeared in the financial sector, and manifested in the creation of the first British banks. After the revolution, with the coming to power of the Dutch Prince, many financiers arrived at London and were spreading the technique of effective Dutch stock transactions. Increased interest of the society to innovation in the financial market and the emergence of new investment opportunities had a positive impact on the development of stock market, government bond market and derivatives market. This, in its turn, led to the appearance of new financial intermediaries such as jobbers, who took over the high risks because of investing of own funds in securities. Such significant changes in the financial system of England became the important prerequisite of the industrial revolution and allowed it to take the leading position in the economic, political and financial area in the world.

    The widespread use of sophisticated electronic tools to monitor data flow and to transact business is alive and well in the oilpatch despite the recent melt-down of dot com companies. By way of illustration the article cites the Alberta government's VIPIR (Volumetric and Infrastructure Petroleum Information Registry) project, which uses state-of-the-art software to gather data from all well sites. This data will assist in the accurate determination of royalties due to the province, and allow spotting of errors almost instantaneously, while reducing the reporting burden on companies. An electronic transfer system will also speed processes of land lease management, bids and transfers, by allowing transactions to be completed on-line. The province is also working on a system called the 'Alberta SuperNet' which will bring high-speed internet access to over 40 towns, villages and remote areas of the province. Concurrently, the National Energy Board is looking at a system that will allow electronic filing of applications. Electronic information transfer systems are also challenging the time -honored SCADA systems. The new systems allow readings to be transmitted daily and alarms to be sounded when problems occur, cutting back on costs by negating operator visits to sites that are running smoothly. The most immediate problem preventing the petroleum industry to truly becoming an e-industry is the lack of standardized software in use by oil, gas, supplier and service companies. Nevertheless, Alberta is said to be leading the world in oil and gas application of structured data management, and it is only a matter of time before industry-specific standards in e-communication will be developed. In the meantime, it is well to remember, that e-business is about business, not technology. Its core function is communication and the connecting of people to information and knowledge, enabling them to work smarter, faster and with greater profitability

  10. Reviewing the evidence to inform the population of cost-effectiveness models within health technology assessments.

    Kaltenthaler, Eva; Tappenden, Paul; Paisley, Suzy

    2013-01-01

    Health technology assessments (HTAs) typically require the development of a cost-effectiveness model, which necessitates the identification, selection, and use of other types of information beyond clinical effectiveness evidence to populate the model parameters. The reviewing activity associated with model development should be transparent and reproducible but can result in a tension between being both timely and systematic. Little procedural guidance exists in this area. The purpose of this article was to provide guidance, informed by focus groups, on what might constitute a systematic and transparent approach to reviewing information to populate model parameters. A focus group series was held with HTA experts in the United Kingdom including systematic reviewers, information specialists, and health economic modelers to explore these issues. Framework analysis was used to analyze the qualitative data elicited during focus groups. Suggestions included the use of rapid reviewing methods and the need to consider the trade-off between relevance and quality. The need for transparency in the reporting of review methods was emphasized. It was suggested that additional attention should be given to the reporting of parameters deemed to be more important to the model or where the preferred decision regarding the choice of evidence is equivocal. These recommendations form part of a Technical Support Document produced for the National Institute for Health and Clinical Excellence Decision Support Unit in the United Kingdom. It is intended that these recommendations will help to ensure a more systematic, transparent, and reproducible process for the review of model parameters within HTA.

  12. Hypercars: The next industrial revolution

    1996-01-01

    The auto industry -- one-seventh of the GNP, and the highest expression of the Iron Age -- is about to trigger the biggest transformation in industrial structure since the microchip. Ultralight cars molded from net-shape advanced composites can be several-fold lighter than present steel cars, yet safer, sportier, and more comfortable, durable, and beautiful. Modern hybrid-electric drives boost efficiency approximately 1.3-1.5x in heavy steel cars, but approximately 5-20x in ultralight, very slippery plafforms. Synergistically combined into ultralight-hybrid 'hypercars,' these elements can yield state-of-the-shelf family cars that average 150-300+ mi/gal -- twice that with state-of-the-art technologies -- yet can also be superior in all other respects, probably including cost: carbon-fiber monocoques can actually be cheaper to mass-produce that steel unibodies. Designing cars more like aircraft and less like tanks requires not only an approximately 400-500 kg curb mass and very low air and road drag, but also an aerospace philosophy of engineering integration. Mass, cost, and complexity turn out to compound with heavy hybrids but to decompound with ultralight hybrids, owing partly to radical simplification. Excellent aerodynamics, preferable including advanced techniques for passive boundary-layer control, will be the key to successful design integration. Transforming automaking is a competitive and environmental imperative, could form the nucleus of a green industrial Renaissance, and would enhance national security by, among other things, saving as much oil as OPEC now extracts. However, this transformation faces serious cultural barriers. For example, hypercars will be more like computers with wheels than like cars with chips -- they'll have an order of magnitude more code than today's cars -- but Detroit is not a software culture. Just the transition from stamped and welded steel to integrated and adhesive-joined synthetics is difficult enough. Nonetheless

    Mutagenesis is a powerful tool used for studying gene function as well as for crop improvement. It is regaining popularity because of the development of effective and cost efficient methods for high-throughput mutation detection. Selection for semi-dwarf phenotype during green revolution has reduced genetic diversity including that for agronomically desirable traits. Most of the available mutant populations in wheat (Triticum aestivum L.) were developed in post-green revolution cultivars. Besides the identification and isolation of agronomically important alleles in the mutant population of pre-green revolution cultivar, this population can be a vital resource for expanding the genetic diversity for wheat breeding. Here we report an Ethylmethane Sulfonate (EMS) generated mutant population consisting of 4,180 unique mutant plants in a pre-green revolution spring wheat cultivar ‘Indian’. Released in early 1900s, ‘Indian’ is devoid of any known height-reducing mutations. Unique mutations were captured by proceeding with single M2 seed from each of the 4,180 M1 plants. Mutants for various phenotypic traits were identified by detailed phenotyping for altered morphological and agronomic traits on M2 plants in the greenhouse and M3 plants in the field. Of the 86 identified mutants, 75 (87%) were phenotypically stable at the M4 generation. Among the observed phenotypes, variation in plant height was the most frequent followed by the leaf morphology. Several mutant phenotypes including looped peduncle, crooked plant morphology, ‘gritty’ coleoptiles, looped lower internodes, and burnt leaf tips are not reported in other plant species. Considering the extent and diversity of the observed mutant phenotypes, this population appears to be a useful resource for the forward and reverse genetic studies.

    Durum wheat (Triticum turgidum L.) is a cereal crop widely grown in the Mediterranean regions; the amber grain is mainly used for the production of pasta, couscous and typical breads. Single nucleotide polymorphism (SNP) detection technologies and high-throughput mutation induction represent a new challenge in wheat breeding to identify allelic variation in large populations. The TILLING strategy makes use of traditional chemical mutagenesis followed by screening for single base mismatches to identify novel mutant loci. Although TILLING has been combined to several sensitive pre-screening methods for SNP analysis, most rely on expensive equipment. Recently, a new low cost and time saving DHPLC protocol has been used in molecular human diagnostic to detect unknown mutations. In this work, we developed a new durum wheat TILLING population (cv. Marco Aurelio) using 0.70-0.85% ethyl methane sulfonate (EMS). To investigate the efficiency of the mutagenic treatments, a pilot screening was carried out on 1,140 mutant lines focusing on two target genes (Lycopene epsilon-cyclase, ε-LCY, and Lycopene beta-cyclase, β-LCY) involved in carotenoid metabolism in wheat grains. We simplify the heteroduplex detection by two low cost methods: the enzymatic cleavage (CelI)/agarose gel technique and the denaturing high-performance liquid chromatography (DHPLC). The CelI/agarose gel approach allowed us to identify 31 mutations, whereas the DHPLC procedure detected a total of 46 mutations for both genes. All detected mutations were confirmed by direct sequencing. The estimated overall mutation frequency for the pilot assay by the DHPLC methodology resulted to be of 1/77 kb, representing a high probability to detect interesting mutations in the target genes. We demonstrated the applicability and efficiency of a new strategy for the detection of induced variability. We produced and characterized a new durum wheat TILLING population useful for a better understanding of key gene functions

    2018-04-01

    On a global basis, adults 65 years of age and older experience falls more frequently than younger individuals, and these often result in severe injuries as well as increased healthcare costs. Gait and balance disorders in this population are among the most common causes of falls and negatively influence quality of life and survivorship. Although falls are a major public health problem and guidelines/recommendations are available to physicians, many are fully aware of different assessments, tools, and resources available for intervention. Given the risk for potentially devastating outcomes if severe injuries occur secondary to a fall, fall prevention strategies in clinical offices is a timely consideration in today's health care landscape. This paper presents a three-tier model, comprising assessment, prevention, and intervention, to highlight methods, proactive programs, and innovative tools and technology that have been developed for fall prevention. Awareness of these resources will enhance the clinician's ability to accurately assess balance and gait, which can improve physical function, and decrease the risk of falls for both average-risk and high-risk older adults.

    Full Text Available The internet and social networks provide new forms of public spaces, virtual continents populated by people of different races, languages, and religions that communicate with a single language, in one unique mode and with one unique tool. In the era of extreme social participation, it is impossible not to consider the role of future policies of education. We cannot ignore the basic language in which the Euro-Mediterranean people recognize themselves, allowing them to interact on all sides of the Mediterranean basin. Technology provides a dialogue bridge, as well as mutual recognition and accreditation for the people who share the Mediterranean Sea and the world. The Internet is the true centre of the Union membership and provides a common good, which generates shared recognition and willingness to communicate; furthermore, it results in the renunciation of personal data protection, as well as the management of its powers to private entities. The aim of this paper is to envisage the effects of the electronic society on the Mediterranean Policies.

    Nuclear material shipping containers have shells of revolution as basic structural components. Analytically modeling the response of these containers to severe accident impact conditions requires a nonlinear shell-of-revolution model that accounts for both geometric and material nonlinearities. Existing models are limited to large displacements, small rotations, and nonlinear materials. The paper presents a finite element model for a nonlinear shell of revolution that will account for large displacements, large strains, large rotations, and nonlinear materials

    2002-07-01

    The 'Casing Drilling' technology, patented by Tesco, which allows operators to simultaneously drill, case and evaluate oil and gas wells, is described. The system is claimed to substantially reduce the amount of lost circulation, loss of well control and bore hole instability problems that have been documented to account for about 25 per cent of total rig time on a well, and at least $4 billion (or 10 per cent of the $40 billion annual global drilling tab) spent on 'unscheduled events' associated with tripping drill pipe. With the Casing Drilling process, wells are drilled using standard oilfield casing instead of drill pipe. The host of downhole problems associated with tripping in and out of the hole are avoided, as the casing pipe is never removed. Instead, drill bits and other downhole tools are tripped through the casing with wireline at a rate of about 500 ft per minute, drastically reducing tripping time. Tesco also developed the portable top drive, the manufacture and rental of which constitutes a large part of the company's business, besides helping technologically to make Casing Drilling possible. Much of the company's success is attributed to the tenacity and zest for innovative approaches of the company's CEO, Bob Tessari, who is largely responsible for the company finding itself at the centre of a drilling technology revolution.

    ``When a white-robed scientist, momentarily looking away from his microscope or cyclotron [or telescope], makes some pronouncement for the general public, he may not be understood but at least he is certain to be believed.'' The truth of this opening sentence of Anthony Standen's 1950 book Science is a Sacred Cow, as clear today as it was then, is the motivation for a new astronomy course at Berry College near Atlanta, GA, USA. To non-scientists, science is known by its products, not by what it is: a human progress. For this illiteracy an antidote is offered: the history of astronomy. In this course the story of the Copernican Revolution is told, for within this story the true nature of science can be found in its fullness. For example, Aristotle's uniform circular motion is used to emphasize the role of assumptions, and the occasional value of wrong ideas is evident in Tycho's theory and in Kepler's universe of perfect solids. Tycho's observations of Mars and Kepler's analysis illustrate the interplay of observation, theory, and technology. As a final example, the indirectness and often-unintentional nature of scientific advance can be seen in the work of Copernicus. The roles of personality and the intersections of science and society are themes throughout the course, as are the merging of disparate fields and the power of strong theories. There are other themes (e.g., coherence, the role of mathematics), but the emphasis is on the science and much of the work is quantitative. There is a laboratory component that features observations and experiments, and in order to bring the narrative to life the class spends two weeks in Poland, the Czech Republic, and Italy, touring sites that are relevant to the story of the Copernican Revolution.

    This paper aims at examining the impacts of shale gas revolution on industrial production in the US. To this end, this paper, first, throughout literature review, exposes the features of shale gas revolution in the US in terms of energy technology and energy markets. However, the potential influences of shale gas extraction on the US economy are not explicit in the existing literature. Thus, considering mainly the output of shale gas revolution on the US economy in this research, later, the paper conducts econometric models to reveal if there exists significant effect(s) of shale gas revolution on the US economy. Therefore, the paper employs unit root tests and cointegration tests by following relevant US monthly data from January 2008 to December 2013. Then, this paper observes long run impact of shale gas production on industrial production in the US through dynamic ordinary least squares estimation with dummy structural breaks and conducts Granger causality test based on vector error correction model. The dynamic ordinary least squares estimator explores that shale gas production has a positive effect on industrial production. Besides, the Granger causality test presents that shale gas production Granger causes industrial production in the long run. Based on the findings of the long run estimations, the paper yields that industrial production is positively related to shale gas production. Eventually, upon its findings, this paper asserts that (i) the shale gas revolution in the US has considerable positive effects on the US economy within the scope of the validity of the growth hypothesis, (ii) new technologies might be developed to mitigate the possible negative environmental effects of shale gas production, (iii) the countries having shale gas reserves, as in US, may follow energy policies to utilize their shale reserves more in the future to meet their energy demand and to increase their economic welfare. - Highlights: • Explores the US shale gas revolution

    2016-04-01

    Major revolutions in energy capture have occurred in both Earth and human history, with each transition resulting in higher energy input, altered material cycles and major consequences for the internal organization of the respective systems. In Earth history, we identify the origin of anoxygenic photosynthesis, the origin of oxygenic photosynthesis, and land colonization by eukaryotic photosynthesizers as step changes in free energy input to the biosphere. In human history we focus on the Palaeolithic use of fire, the Neolithic revolution to farming, and the Industrial revolution as step changes in free energy input to human societies. In each case we try to quantify the resulting increase in energy input, and discuss the consequences for material cycling and for biological and social organization. For most of human history, energy use by humans was but a tiny fraction of the overall energy input to the biosphere, as would be expected for any heterotrophic species. However, the industrial revolution gave humans the capacity to push energy inputs towards planetary scales and by the end of the 20th century human energy use had reached a magnitude comparable to the biosphere. By distinguishing world regions and income brackets we show the unequal distribution in energy and material use among contemporary humans. Looking ahead, a prospective sustainability revolution will require scaling up new renewable and decarbonized energy technologies and the development of much more efficient material recycling systems - thus creating a more autotrophic social metabolism. Such a transition must also anticipate a level of social organization that can implement the changes in energy input and material cycling without losing the large achievements in standard of living and individual liberation associated with industrial societies.

  12. Rotor Wake Development During the First Revolution

    2003-01-01

    The wake behind a two-bladed model rotor in light climb was measured using particle image velocimetry, with particular emphasis on the development of the trailing vortex during the first revolution of the rotor. The distribution of vorticity was distinguished from the slightly elliptical swirl pattern. Peculiar dynamics within the void region may explain why the peak vorticity appeared to shift away from the center as the vortex aged, suggesting the onset of instability. The swirl and axial velocities (which reached 44 and 12 percent of the rotor-tip speed, respectively) were found to be asymmetric relative to the vortex center. In particular, the axial flow was composed of two concentrated zones moving in opposite directions. The radial distribution of the circulation rapidly increased in magnitude until reaching a point just beyond the core radius, after which the rate of growth decreased significantly. The core-radius circulation increased slightly with wake age, but the large-radius circulation appeared to remain relatively constant. The radial distributions of swirl velocity and vorticity exhibit self-similar behaviors, especially within the core. The diameter of the vortex core was initially about 10 percent of the rotor-blade chord, but more than doubled its size after one revolution of the rotor. According to vortex models that approximate the measured data, the core-radius circulation was about 79 percent of the large-radius circulation, and the large-radius circulation was about 67 percent of the maximum bound circulation on the rotor blade. On average, about 53 percent of the maximum bound circulation resides within the vortex core during the first revolution of the rotor.

    The spatial distribution of population is closely related to land use and land cover (LULC) patterns on both regional and global scales. Population can be redistributed onto geo-referenced square grids according to this relation. In the past decades, various approaches to monitoring LULC using remote sensing and Geographic Information Systems (GIS) have been developed, which makes it possible for efficient updating of geo-referenced population data. A Spatial Population Updating System (SPUS) is developed for updating the gridded population database of China based on remote sensing, GIS and spatial database technologies, with a spatial resolution of 1 km by 1 km. The SPUS can process standard Moderate Resolution Imaging Spectroradiometer (MODIS L1B) data integrated with a Pattern Decomposition Method (PDM) and an LULC-Conversion Model to obtain patterns of land use and land cover, and provide input parameters for a Population Spatialization Model (PSM). The PSM embedded in SPUS is used for generating 1 km by 1 km gridded population data in each population distribution region based on natural and socio-economic variables. Validation results from finer township-level census data of Yishui County suggest that the gridded population database produced by the SPUS is reliable. PMID:22399959

    In this paper, we study the relation between conserved quantities of nonholonomic systems and the hamiltonization problem employing the geometric methods of Balseiro (Arch Ration Mech Anal 214:453-501, 2014) and Balseiro and Garcia-Naranjo (Arch Ration Mech Anal 205(1):267-310, 2012). We illustrate the theory with classical examples describing the dynamics of solids of revolution rolling without sliding on a plane. In these cases, using the existence of two conserved quantities we obtain, by means of gauge transformations and symmetry reduction, genuine Poisson brackets describing the reduced dynamics.

    This article will describe how a revolution in customer service provision beginning in 2002 has led to an evolution of library services. When the reference and circulation desks were merged to create a single service point, responsibilities were broadened, core competencies were developed, and staff members were cross trained. In 2005, an analysis of staffing and work patterns demonstrated a need to build upon the original model to better utilize staff and ensure coverage of the desk. Reference librarians were moved to "on call" status, technical services staff were added to the schedule, and core competencies and procedures were refined.

    The novel understanding of the physical world that characterized the Scientific Revolution depended on a fundamental shift in the way its protagonists understood and described space. At the beginning of the seventeenth century, spatial phenomena were described in relation to a presupposed central point; by its end, space had become a centerless void in which phenomena could only be described by reference to arbitrary orientations. David Marshall Miller examines both the historical and philosophical aspects of this far-reaching development, including the rejection of the idea of heavenly sphere

    2016-12-01

    Full Text Available The question about the causes and actors of the February revolution can be understood only in the context of previous events. In this connection, of great importance is the analysis of the causes and circumstances of a strike wave that swept through Petrograd in October 1916. Up to 100 thousand strikers (together with locked-out workers were involved in these labor unrests that were accompanied by demonstrations and clashes with the police. In many ways (bread shortage as the main motivation, bakeshops pillage, spontaneity, suddenness, involvement of adolescents and women, Cossacks’ refusal to shoot into the crowd, solders’ desertion to the side of people, these events recall those of February 23–28, 1917. The American historians L. Haimson and E. Brian called them “a try-out of the February revolution”. Short information about these strikes is available in the papers of a number of Soviet authors; however, it is presented to some extent tendentiously, based on the desire to show the directing and organizational role of the Bolshevik party. In this regard, it seems important to restore the actual course of the events and give them an objective interpretation. The study shows that the October strikes were the first reaction of Petrograd workers to the emerging food crisis, whereas the February revolution was the reaction to the second, a much more acute phase of this crisis. The mechanism of these events was similar: in the both cases, famine was the major factor pushing for protests. In the both cases, protests were spontaneous and massive, externally similar to a hunger riot. The food crisis determined the army’s position as well: both in October and in February, Cossacks and soldiers sympathized with the starving population and refused to use weapons to crackdown demonstrators

    Human reproduction and development are contrasted; they are intimately linked despite the fact that they may be considered antitheses of each other from many points of view. Presently technological development and the advance of humans into every available corner of living space threaten to place the whole world environment in danger. The Green revolution of the 1960s addressed problems of underproduction of food for the world's population, without providing for the effective distribution of the new surpluses, and without addressing the problem of the ecological impact. 2 trends which are regarded by some with alarm: the migration of populations to the cities and the aging of the population with the connected burden on health care systems, are inevitable, and it is not clear that they are completely negative trends. Addressing these issues will have positive effects in the long run: congestion in the cities, the result of mechanization of rural industry which also results in a greater abundance of agricultural products necessary to society, should force serious consideration of problems such as solid waste management. Coming to terms with the costs of intervention to save lives among the very frail elderly and the prematurely born will have the effect of bringing controversial topics such as euthenasia and eugenics to discussion. The important role played by economic development in the braking of population expansion is underlined.

  1. Cooperation, norms, and revolutions: a unified game-theoretical approach.

    Directory of Open Access Journals (Sweden)

    Dirk Helbing

    Full Text Available BACKGROUND: Cooperation is of utmost importance to society as a whole, but is often challenged by individual self-interests. While game theory has studied this problem extensively, there is little work on interactions within and across groups with different preferences or beliefs. Yet, people from different social or cultural backgrounds often meet and interact. This can yield conflict, since behavior that is considered cooperative by one population might be perceived as non-cooperative from the viewpoint of another. METHODOLOGY AND PRINCIPAL FINDINGS: To understand the dynamics and outcome of the competitive interactions within and between groups, we study game-dynamical replicator equations for multiple populations with incompatible interests and different power (be this due to different population sizes, material resources, social capital, or other factors. These equations allow us to address various important questions: For example, can cooperation in the prisoner's dilemma be promoted, when two interacting groups have different preferences? Under what conditions can costly punishment, or other mechanisms, foster the evolution of norms? When does cooperation fail, leading to antagonistic behavior, conflict, or even revolutions? And what incentives are needed to reach peaceful agreements between groups with conflicting interests? CONCLUSIONS AND SIGNIFICANCE: Our detailed quantitative analysis reveals a large variety of interesting results, which are relevant for society, law and economics, and have implications for the evolution of language and culture as well.

  2. Scientific pluralism and the Chemical Revolution.

    2015-02-01

    In a number of papers and in his recent book, Is Water H2O? Evidence, Realism, Pluralism (2012), Hasok Chang has argued that the correct interpretation of the Chemical Revolution provides a strong case for the view that progress in science is served by maintaining several incommensurable "systems of practice" in the same discipline, and concerning the same region of nature. This paper is a critical discussion of Chang's reading of the Chemical Revolution. It seeks to establish, first, that Chang's assessment of Lavoisier's and Priestley's work and character follows the phlogistonists' "actors' sociology"; second, that Chang simplifies late-eighteenth-century chemical debates by reducing them to an alleged conflict between two systems of practice; third, that Chang's evidence for a slow transition from phlogistonist theory to oxygen theory is not strong; and fourth, that he is wrong to assume that chemists at the time did not have overwhelming good reasons to favour Lavoisier's over the phlogistonists' views.

    Kickbusch, I; Reddy, K S

    2015-07-01

    The recent Ebola crisis has re-opened the debate on global health governance and the role of the World Health Organization. In order to analyze what is at stake, we apply two conceptual approaches from the social sciences - the work on gridlock and the concept of cosmopolitan moments - to assess the ability of the multilateral governance system to reform. We find that gridlock can be broken open by a health crisis which in turn generates a political drive for change. We show that a set of cosmopolitan moments have led to the introduction of the imperative of health in a range of policy arenas and moved health into 'high politics' - this has been called a political revolution. We contend that this revolution has entered a second phase with increasing interest of heads of state in global health issues. Here lies the window of opportunity to reform global health governance.

    The aim of this paper is to analyze the impact of the so-called “shale oil revolution” on oil prices and economic growth. We employ a general equilibrium model of the world oil market in which Saudi Arabia is the dominant firm, with the rest of the producers as a competitive fringe. Our results suggest that most of the expected increase in US oil supply due to the shale oil revolution has already been incorporated into prices and that it will produce an additional increase of 0.2% in the GDP of oil importers in the period 2010–2018. We also employ the model to analyze the collapse in oil prices in the second half of 2014 and conclude that it was mainly due to positive unanticipated supply shocks. - Highlights: • We analyze the impact of the “shale oil revolution” on oil prices and economic growth. • We employ a general equilibrium model of the oil market in which Saudi Arabia is the dominant firm. • We find that most of the shale oil revolution is already priced in. • We also analyze the decline in oil prices in the second half of 2014. • We find that unanticipated supply shocks played the major role in the fall.

    Since conventional treatment technologies may fail in removing many micro-pollutants, there is currently a focus on the potential of additional treatment technologies for improved sewage treatment. The aim of the present study was to evaluate six different effluents from Henriksdal Sewage Treatment Plant in Stockholm, Sweden. The effluents were; conventionally treated effluent (chemical phosphorous removal in combination with an activated sludge process, including biological nitrogen removal and a sand filter), with additional treatments individually added to the conventional treatment; active carbon filtration, ozonation at 5 mg l(-1), ozonation at 15 mg l(-1), ozonation at 5 mg l(-1)+moving bed biofilm reactor and irradiation with ultraviolet radiation+hydrogen peroxide. The evaluation was done by characterizing and comparing the effluents using a Lefkovitch matrix model based on a life cycle test with the harpacticoid copepod Nitocra spinipes, combined with analysis of juvenile development and survival over time. The conventionally treated effluent resulted in the most negative effects, leading to the conclusion that all additional treatments in the present study created effluents with less negative impacts on the copepod populations. The ozone treatments with the low dose treatment in particular, resulted in the overall least negative effects. Moving bed biofilm reactor combined with ozone did not improve the quality of the effluent in the sense that slightly more negative effects on the population abundance were seen for this treatment technology compared to ozonation alone. The active carbon treatment had more negative effects than the ozone treatments, most of which could possibly be explained by removal of essential metal ions. The effluent which was treated with ultraviolet radiation+hydrogen peroxide resulted in few developmental and survival effects over time, but still showed negative effects on the population level. Matrix population modeling proved a

    1996-01-01

    The information revolution provides an opportunity for the Canadian nuclear industry to reinvigorate the information environment that supports companies and employees in achieving business and personal goals. Five necessary steps are to intensify the information environment; develop a new human resources model that stresses access to, and sharing of, information, and which comes to grips with the need for better programs to retrain and retain employees and to accommodate the 'mercenary' workforce; promote awareness of the information revolution; nurture individual initiatives; and develop an integrated approach called information engineering, which involves collaborative work between information technology, information management, and human resources. At the heart of all of these steps is the need for a new way of thinking about information and a determination to share information widely within our organisations and industry. Applying the recommended approaches within our industry will enable us to compete successfully in a global marketplace in which we are outnumbered and out gunned. (author)

  17. Guatemala's green revolution: synthetic fertilizer, public health, and economic autonomy in the Mayan highland.

    Carey, David

    2009-01-01

    Despite extensive literature both supporting and critiquing the Green Revolution, surprisingly little attention has been paid to synthetic fertilizers' health and environmental effects or indigenous farmers' perspectives. The introduction of agrochemicals in the mid-twentieth century was a watershed event for many Mayan farmers in Guatemala. While some Maya hailed synthetic fertilizers' immediate effectiveness as a relief from famines and migrant labor, other lamented the long-term deterioration of their public health, soil quality, and economic autonomy. Since the rising cost of agrochemicals compelled Maya to return to plantation labor in the 1970s, synthetic fertilizers simply shifted, rather than alleviated, Mayan dependency on the cash economy. By highlighting Mayan farmers' historical narratives and delineating the relationship between agricultural science and postwar geopolitics, the constraints on agriculturists' agency become clear. In the end, politics, more than technology or agricultural performance, influenced guatemala's shift toward the Green Revolution.

    2016-01-01

    The French nuclear industry is undergoing tremendous change. France has lost its leader place in the competition to build reactors and today's priority is to realize important competitiveness gains. Nuclear industry must become more flexible concerning the management and integration of innovation at any stage of any nuclear activity and the digital revolution will help to do so by easing cooperation between various enterprises. A joint team composed of engineers from AREVA and EDF is working in the EPR-NM project whose purpose is to re-invent the EPR reactor in order to make it more competitive by a factor 20-30%. The deployment of digital-based technologies in nuclear industry appears late when compared to other industries like aviation industry but it could benefit from the feedback experience. The additive manufacturing already exists to fabricate some small pieces of a plane. The nuclear activities that could benefit from the application of digital-based technologies like connected objects is the monitoring of the fabrication of components, the quality control and the optimization of maintenance.

We...... then extend the analysis to allow for repeated matching over many periods, modeling the shotgun-marriage, contraception- method and abortion margins. We use US survey data on contraception, sexual activity and family dynamics to calibrate the model for the 1970s, and then compute the effects of liberalizing...

    A patient entering a dental office is often greeted and then checked in through the practice management system's digital appointment book. The provider is notified by an electronic signal that is visual, audible, or both. The patient is led to the treatment area and sits in a dental chair which is adjusted to the individual's size and position for the treatment, and the light is positioned. Sometimes a radiograph is taken, local anesthetic is delivered, and a handpiece--air turbine or electric--is used for the procedure. How different is this process today from a dentist treating a patient in 1864?

    Mechanistically, how epigenetic states are inherited through cellular divisions remains an important open question in the chromatin field and beyond. Defining the heritability of epigenetic states and the underlying chromatin-based mechanisms within a population of cells is complicated due to cell heterogeneity combined with varying levels of stability of these states; thus, efforts must be focused toward single-cell analyses. The approaches presented here constitute the forefront of epigenetics research at the single-cell level using classic and innovative methods to dissect epigenetics mechanisms from the limited material available in a single cell. This review further outlines exciting future avenues of research to address the significance of epigenetic heterogeneity and the contributions of microfluidics technologies to single-cell isolation and analysis.

  6. A Comprehensive Plan for Global Energy Revolution

    Science.gov (United States)

    Blees, T.

    2009-05-01

    There is no dearth of information regarding the grave crises faced by humanity in the 21st century. There is also growing consensus that the wholesale burning of fossil fuels must come to an end, either because of climate change or other still-salient reasons such as air pollution or major conflicts over dwindling reserves of cheaply recoverable oil and gas resources. At the same time, global demographics predict with disquieting certainty a world with up to 9 or 10 billion souls by mid-century. The vast expansion of energy consumption that this population represents, along with further increases in already-unacceptable levels of atmospheric carbon dioxide from fossil fuel burning, demands that we quickly develop almost limitless sources of clean, economical power. What is sorely lacking in the public debate are realistic solutions. Expanding wind and solar generating capacity is an important near-term goal, but neither of these technologies represents a viable solution for generating base load power at the vast scales that will be required. Energy efficiency measures are likewise well-directed, but the combination of rising population along with increasingly energy-intensive economic activity by the large fraction of Earth's current population residing in developing nations suggests that absolute energy demand will continue to rise even with radically improved energy efficiency. Fortunately we have the technologies available to provide virtually unlimited clean energy, and to utilize and recycle our resources so that everyone can improve their standard of living. The Integral Fast Reactor (IFR), developed at the Argonne National Laboratory in the 80's and 90's and currently championed by General Electric, is a technology that fills the bill on every count, and then some. IFRs are safe, environmentally clean, economical, and free of conflict over fuel supply. IFRs can safely consume as fuel the nuclear waste from the current installed base of light-water reactors

    2000-02-01

    This study illustrates the potential of small-game data for identifying and dating Paleolithic demographic pulses such as those associated with modern human origins and the later evolution of food-producing economies. Archaeofaunal series from Israel and Italy serve as our examples. Three important implications of this study are that (1) early Middle Paleolithic populations were exceptionally small and highly dispersed, (2) the first major population growth pulse in the eastern Mediterranean probably occurred before the end of the Middle Paleolithic, and (3) subsequent demographic pulses in the Upper and Epi-Paleolithic greatly reshaped the conditions of selection that operated on human subsistence ecology, technology, and society. The findings of this study are consistent with the main premise of Flannery's broad-spectrum-revolution hypothesis. However, ranking small prey in terms of work of capture (in the absence of special harvesting tools) proved far more effective in this investigation of human diet breadth than have the taxonomic-diversity analyses published previously.

    Johannesen, Kasper M; Claxton, Karl; Sculpher, Mark J; Wailoo, Allan J

    2018-02-01

    This paper presents a conceptual framework to analyse the design of the cost-effectiveness appraisal process of new healthcare technologies. The framework characterises the appraisal processes as a diagnostic test aimed at identifying cost-effective (true positive) and non-cost-effective (true negative) technologies. Using the framework, factors that influence the value of operating an appraisal process, in terms of net gain to population health, are identified. The framework is used to gain insight into current policy questions including (a) how rigorous the process should be, (b) who should have the burden of proof, and (c) how optimal design changes when allowing for appeals, price reductions, resubmissions, and re-evaluations. The paper demonstrates that there is no one optimal appraisal process and the process should be adapted over time and to the specific technology under assessment. Optimal design depends on country-specific features of (future) technologies, for example, effect, price, and size of the patient population, which might explain the difference in appraisal processes across countries. It is shown that burden of proof should be placed on the producers and that the impact of price reductions and patient access schemes on the producer's price setting should be considered when designing the appraisal process.

  12. Revolution, Romanticism and the Long Nineteenth Century

    Directory of Open Access Journals (Sweden)

    Adriana Craciun

    2006-04-01

    Full Text Available In order to consider the future of Victorian literary studies within the long nineteenth century, we must go back to that earlier “period” of the nineteenth century, and the French Revolution of 1789. Drawing on the aesthetic and political innovations of 1790s women's writings, this essay argues that we need to reconceive of nineteenth-century literary studies beyond the period boundaries of Romantic and Victorian. The sexualization of revolutionary Terror, and particularly of Robespierre, in Romantic-era writings by women like Helen Maria Williams, Mary Robinson and Fanny Burney, offers surprising precedents for the feminization of Terror associated with the retrospectives of Victorian writers like Carlyle and Dickens. In this respect, and given many other aesthetic continuities (for example, the crossgender and cross-period appeal of the “poetess” figure, the “Victorian period” appears increasingly unsatisfactory when compared to the merits of a long nineteenth-century model for literary studies.

Finally, Professor Herzlinger returns to the subject with a response to these physician executives.

  14. The quiet revolution: decentralisation and fuel cells

    International Nuclear Information System (INIS)

    Aschenbrenner, N.

    2003-01-01

    This article discusses how major changes in the electricity supply industry can take place in the next few years due to market liberalisation and efforts to reduce the emission of greenhouse gasses. Decentralisation is discussed as being a 'mega-trend' and fuel cells in particular are emphasised as being a suitable means of generating heat and power locally, i.e. where they are needed. Also, the ecological advantages of using natural gas to 'fire' the fuel cell units that are to complement or replace coal-fired or gas-fired combined gas and steam-turbine power stations is discussed. Various types of fuel cell are briefly described. Market developments in the USA, where the power grid is extensive and little reserve capacity is available, are noted. New designs of fuel cell are briefly examined and it is noted that electricity utilities, originally against decentralisation, are now beginning to promote this 'quiet revolution'

The study adopts a blended netnography/ethnography approach to data collection and analysis. My original data consist of 2 hrs of recorded discussions of 60 Tunisian students and a total of 300 online humorous posts collected from the social network Facebook (FB. The data revealed that Tunisians interacting via FB used two main types of situational humor: Third party insult and Alternate reality. These two types of humor were found to be associated with a variety of psychological and social functions and to serve as effective interpersonal strategies to construct group cohesion, strengthen shared attitudes and beliefs, and develop relational identity.

  16. Silicon: Child and Progenitor of Revolution

    Science.gov (United States)

    Cahn, R. W.

    Antoine Lavoisier, the pioneering French chemist who (together with Joseph Priestley in England) identified oxygen as an element and gave it its name, in 1789 concluded that quartz was probably a compound with an as-yet undiscovered but presumably extremely common element. That was also the year in which the French Revolution broke out. Five years later, the Jacobins accused Lavoisier of offences against the people and cut off his head, thereby nearly cutting off the new chemistry. It was not until 1824 that Jöns Berzelius in Sweden succeeded in confirming Lavoisier's speculation by isolating silicon. Argument at once broke out among the scientific elite as to whether the newly found element was a metal or an insulator. It took more than a century to settle that disagreement decisively: As so often, when all-or-nothing alternatives are fiercely argued, the truth turned out to be neither all nor nothing.

  18. Counting nodal domains on surfaces of revolution

    International Nuclear Information System (INIS)

    Karageorge, Panos D; Smilansky, Uzy

    2008-01-01

    We consider eigenfunctions of the Laplace-Beltrami operator on special surfaces of revolution. For this separable system, the nodal domains of the (real) eigenfunctions form a checkerboard pattern, and their number ν n is proportional to the product of the angular and the 'surface' quantum numbers. Arranging the wavefunctions by increasing values of the Laplace-Beltrami spectrum, we obtain the nodal sequence, whose statistical properties we study. In particular, we investigate the distribution of the normalized counts ν n /n for sequences of eigenfunctions with K ≤ n ≤ K + ΔK, where K, ΔK element of N. We show that the distribution approaches a limit as K, ΔK → ∞ (the classical limit), and study the leading corrections in the semi-classical limit. With this information, we derive the central result of this work: the nodal sequence of a mirror-symmetric surface is sufficient to uniquely determine its shape (modulo scaling)

The calculations are performed assuming the geometry perfect, the deformations slight and the behaviour of the material perfectly elastic. The results obtained are presented favourably by plotting a reduced pressure p* against the geometry. A good definition of p* would be: p*=pπ 2 E/1-μ 2 .e 2 b 2 /a 4 (p* critical pressure, E Young's modulus, μ Poisson's coefficient, e thickness, a half large axis, b half small axis). When a/b is above 2 the p value remains close to 1. For lower a/b values the p value rises considerably with a/b [fr

  20. Owning the Revolution: Race, Revolution, and Politics from Havana to Miami, 1959–1963

    Full Text Available “Owning the Revolution” explores the role that conversations about race and racism played in defining the 1959 Cuban Revolution both on the island and in South Florida, where over half of the exiles fled. It highlights how revolutionary leaders challenged internal and external opposition movements by publicly labeling dissenters “counterrevolutionaries” and “racists.” Using the label “racist” to attack an opponent was not altogether new in the 1960s, but by linking the term to counterrevolution, national discussions occurring in newspapers, magazines, and on television defined public racism as existing outside of the norms of a new Cuba. Exiles disagreed with this identification and accused the revolution of betraying the nineteenth-century colorblind goals of Jose Martí. Exile leaders in Miami argued that Castro invented racial tensions and claimed that their fight was not with blacks or mulatos but with “red” or communist Cubans. The politics expressed by white exile newspapers, however, did not always fit with the concerns of Afro-Cubans in the United States. Miami Cubans failed to acknowledge the persistence of racism in new exile communities in the same way that the revolutionary government dismissed racism on the island. These parallel silences exemplify the dangers of polarized narratives that imagine the revolution as antiracist and the exile community as racist.

    1975-01-01

    DYNAPLAS is a program for the transient response of ring stiffened shells of revolution subjected to either asymmetric initial velocities or to asymmetric pressure loadings. Both material and geometric nonlinearities may be considered. The present version, DYNAPLAS II, began with the programs SAMMSOR and DYNASOR. As is the case for the earlier programs, a driver program, SAMMSOR III, generates the stiffness and mass matrices for the harmonics under consideration. A highly refined meridionally curved axisymmetric thin shell of revolution element is used in conjunction with beam type ring stiffeners in the circumferential direction. The shell element uses a cubic displacement function and through static condensation a basic eight degree of freedom element is generated. The shell material may be isotropic or orthotropic. DYNAPLAS II uses the 'displacement' method of analysis in which the nonlinearities are treated as pseudo loads on the right-hand side of the equations of motion. The equations are written for each Fourier harmonic used in representing the asymmetric loading components, and although the left-hand side of the equations is uncoupled, the right-hand side is coupled by the nonlinear pseudo loads. The strain displacement equations of Novozhilov are used and the incremental theory of plasticity is used with the von Mises yield condition and associated flow rule. Either isotropic work hardening or the mechanical sublayer model may be used. Strain rate effects may be included. Either the explicit central difference method or the implcit Houbolt method are available. The program has found use in the analysis of containment vessels for light water reactors

    Current developmental toxicity testing adheres largely to protocols suggested in 1966 involving the administration of test compound to pregnant laboratory animals. After more than 50 years of embryo-fetal development testing, are we ready to consider a different approach to human developmental toxicity testing? A workshop was held under the auspices of the Developmental and Reproductive Toxicology Technical Committee of the ILSI Health and Environmental Sciences Institute to consider how we might design developmental toxicity testing if we started over with 21st century knowledge and techniques (revolution). We first consider what changes to the current protocols might be recommended to make them more predictive for human risk (evolution). The evolutionary approach includes modifications of existing protocols and can include humanized models, disease models, more accurate assessment and testing of metabolites, and informed approaches to dose selection. The revolution could start with hypothesis-driven testing where we take what we know about a compound or close analog and answer specific questions using targeted experimental techniques rather than a one-protocol-fits-all approach. Central to the idea of hypothesis-driven testing is the concept that testing can be done at the level of mode of action. It might be feasible to identify a small number of key events at a molecular or cellular level that predict an adverse outcome and for which testing could be performed in vitro or in silico or, rarely, using limited in vivo models. Techniques for evaluating these key events exist today or are in development. Opportunities exist for refining and then replacing current developmental toxicity testing protocols using techniques that have already been developed or are within reach. © 2018 The Authors.

    2016-07-01

    Full Text Available Cannabis is a predominantly diecious phenotypically diverse domesticated genus with few if any extant natural populations. International narcotics conventions and associated legislation have constrained the establishment, characterization and use of Cannabis genetic resource collections. This has resulted in the underutilization of genepool variability in cultivar development and has limited the inclusion of secondary genepools associated with genetic improvement strategies of the Green Revolution. The structured screening of ex situ germplasm and the exploitation of locally-adapted intraspecific traits is expected to facilitate the genetic improvement of Cannabis. However, limited attempts have been made to establish the full extent of genetic resources available for pre-breeding. We present a thorough critical review of Cannabis ex situ genetic resources, and discuss recommendations for conservation, pre-breeding characterization and genetic analysis that will underpin future cultivar development. We consider East Asian germplasm to be a priority for conservation based on the prolonged historical cultivation of Cannabis in this region over a range of latitudes, along with the apparent high levels of genetic diversity and relatively low representation in published genetic resource collections. Seed cryopreservation could improve conservation by reducing hybridization and genetic drift that may occur during Cannabis germplasm regeneration. Given the unique legal status of Cannabis, we propose the establishment of a global virtual core collection based on the collation of consistent and comprehensive provenance meta-data and the adoption of high-throughput DNA sequencing technologies. This would enable representative core collections to be used for systematic phenotyping, and so underpin breeding strategies for the genetic improvement of Cannabis.

    Digital flat-panel X-ray detectors offer excellent image quality and dose efficiency in addition to clinical productivity, connectivity, and adaptability to advanced clinical applications. GE's Revolution systems provide two modes of exposure control for setting the dose operating point, fixed time and automatic exposure control, the latter of which maintains high image signal-to-noise ratio for the given technique settings. In addition to enhancing detail contrast and compressing the dynamic range, postprocessing automatically determines the best window level and width for display, taking into account the dose at which the image was acquired. Several studies have examined the reduction in patient dose achievable with Revolution systems as compared to competing technologies, and results indicate significant dose savings with equivalent or superior image quality. For pediatric exams, pediatric default techniques provide for a lower patient dose as compared to adult techniques. Therefore, GE's Revolution systems can achieve a high image quality-to-dose ratio for pediatric imaging using the combined advantages of dose-efficient detection, advanced postprocessing, and independently adjustable pediatric techniques.

    Digital revolution is one of the major global trends resulting in the unprecedented scale and depth of penetration of information and communication technologies into all sectors of national economy, including healthcare. The development of this trend brought about high expectations related to the improvement of quality of medical assistance, accessibility and economic efficiency of healthcare services. However, euphoria of the first steps of digital revolution is passing now, opening doors to more realistic analysis of opportunities and conditions of realization of the true potential hidden in the digital transformation of healthcare. More balanced perception of the peculiarities of innovation processes in the sector is coming together with understanding of the serious barriers, hampering implementation of the new ideas and practices due to complicated interweaving of social, economic, ethical and psychological factors. When taking into account the industry specifics it becomes evident that digital revolution cannot be a quick turnaround but rather would pass a number of phases and is likely to last more than one decade. In this context the article focuses on the prospects of the new business models, capable of making significant changes in today’s economic landscape of the sector (including uber-medicine, retail clinics, retainer medicine, network models of medical services). The authors also provide assessment of the current situation and perspectives of digital healthcare development in Russia.

    This report proposes an overview of LTO (Light Tight Oil or shale oil) production in the USA, and examines the consequences of oil price fall on its future level. The first part gives an assessment of five years of this revolution which follows the shale gas revolution. It addresses the most remarkable evolutions: spectacular development of production, decrease of oil imports, increase of oil product exports, and a move towards oil independence. The second part highlights some peculiarities of shale oils and of the resulting business model which is much different from the Exploration/Production model for conventional oil. It analyses the LTO economy and breakeven prices required for a continued investment. Technological advances which are at the basis of this revolution are addressed, and expected improvements on a short or medium term are described. The main financial indicators are then presented as the financial situation of LTO producers is a crucial factor for future investment levels. The last chapter reports the study of the impact of price decrease on capital expenditures (CAPEX) of American producers, and on the drilling activity. It seems that LTO production will resist to price decrease

    Astronomy is going through a scientific revolution, responding to a flood of data from the Hubble Space Telescope, other space missions, and large telescopes on the ground. In this talk, I will discuss some of the important discoveries of the last decade, from dwarf planets in the outer Solar System to the mysterious dark energy that overcomes gravity to accelerate the expansion of the Universe. The next decade will be equally bright with the newly refurbished Hubble and the promise of its successor, the James Webb Space Telescope. An infrared-optimized 6.5m space telescope, Webb is designed to find the first galaxies that formed in the early universe and to peer into the dusty gas clouds where stars and planets are born. With MEMS technology, a deployed primary mirror and a tennis-court sized sunshield, the mission presents many technical challenges. I will describe Webb's scientific goals, its design and recent progress in constructing the observatory. Webb is scheduled for launch in 2014.

    Solar cells have been considered as one of the foremost solutions to energy and environmental problems because of clean, high efficiency, cost-effective, and inexhaustible features. The historical development and state-of-the-art solar cells mainly focus on elevating photoelectric conversion efficiency upon direct sunlight illumination. It is still a challenging problem to realize persistent high-efficiency power generation in rainy, foggy, haze, and dark-light conditions (night). The physical proof-of-concept for all-weather solar cells opens a door for an upcoming photovoltaic revolution. Our group has been exploring constructive routes to build all-weather solar cells so that these advanced photovoltaic technologies can be an indication for global solar industry in bringing down the cost of energy harvesting. How the all-weather solar cells are built without reducing photo performances and why such architectures can realize electricity outputs with no visible-light are discussed. Potential pathways and opportunities to enrich all-weather solar cell families are envisaged. The aspects discussed here may enable researchers to develop undiscovered abilities and to explore wide applications of advanced photovoltaics. © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

    2011-10-01

    Rapid advances in molecular technologies are continually re-shaping the way we view and understand the mechanisms driving oncogenesis. The last decade has witnessed unparalleled change in the biology and therapy of the myelodysplastic syndromes (MDS), a heterogeneous collection of clonal myeloid disorders characterised by ineffective haematopoiesis and susceptibility to acute leukaemia transformation. Pivotal studies demonstrating the positive effects of hypomethylating agents on clinical outcome have brought an 'epigenomics revolution' to this disease, emphasising the importance of epigenetic mechanisms to the underlying pathogenesis of MDS. One of the most important future challenges in the MDS field will be to determine whether epigenetic therapies can be made more 'targeted' through identification of biomarkers which define subsets of patients most likely to benefit from treatment. A wave of novel mutations have recently been reported in MDS and other myeloid disorders, several of which regulate endogenous methylation networks within cells (including TET2, DNMT3A, IDH and EZH2). The relevance of these lesions in being able to predict response to epigenetic modulators and their correlation with epigenetic signatures in MDS are beginning to emerge.

    The Asian green revolution trebled grain yields through agrochemical intensification of monocultures. Associated environmental costs have subsequently emerged. A rapidly changing world necessitates sustainability principles be developed to reinvent these technologies and test them at scale. The need is particularly urgent in Africa, where ecosystems are degrading and crop yields have stagnated. An unprecedented opportunity to reverse this trend is unfolding in Malawi, where a 90% subsidy has ensured access to fertilization and improved maize seed, with substantive gains in productivity for millions of farmers. To test if economic and ecological sustainability could be improved, we preformed manipulative experimentation with crop diversity in a countrywide trial (n = 991) and at adaptive, local scales through a decade of participatory research (n = 146). Spatial and temporal treatments compared monoculture maize with legume-diversified maize that included annual and semiperennial (SP) growth habits in temporal and spatial combinations, including rotation, SP rotation, intercrop, and SP intercrop systems. Modest fertilizer intensification doubled grain yield compared with monoculture maize. Biodiversity improved ecosystem function further: SP rotation systems at half-fertilizer rates produced equivalent quantities of grain, on a more stable basis (yield variability reduced from 22% to 13%) compared with monoculture. Across sites, profitability and farmer preference matched: SP rotations provided twofold superior returns, whereas diversification of maize with annual legumes provided more modest returns. In this study, we provide evidence that in Africa, crop diversification can be effective at a countrywide scale, and that shrubby, grain legumes can enhance environmental and food security.

    2017-11-01

    Since 1987 [1,2,3,4,5] the global jet engine community is facing the historical fact that jet engine steering is gradually replacing canards and the common, often dangerous and obsolete, aerodynamic-only flight control - a fact that (i) has already affected the defense-industrial complex in the US, Russia, China, Japan, S-Korea and India, (ii) has integrated the traditional jet-engine components R&D with advanced aero-electro-physics, stealth technology, thrust vectoring aerodynamics and material science. Moreover, this military revolution is historically due to expand into the civil transport jets domain, [6,7,8,9]. The historical aim of the JES-Revolution remains the same: Replace the common, stall-spin sensitive canards [6] and Aerodynamic-Only-Obsolete-Flight Control ("AOOF Control"). Invented about 100 years ago for propeller-driven air vehicles, it has already been partially replaced for failure to function in WVR-combat post-stall domain, and for the following reasons: In comparison with complete Tail-Less, Canard-Less, Stealth-JES (Figure 5 and References [1,2,3,4,5,6]), the common AOOF Control increases drag, weight, fuel consumption, complexity, cost, and reduces flight safety, stealth, [Low Detectability] and provides zero post-stall, WVR air combat capability while its CANARDS KILL LD & REDUCE JES. Examples of stealth fighter aircraft that have already replaced canards and AOOF-Control where JES provides at least 64 to 0 KILL-RATIO advantage over AOOF-Controlled conventional fighter aircraft: The U.S. JES F-22 and, apparently, the Russian JES-Su-T-50 & 35S, China 2016-J-31, Indian HAL AMCA & FGFA, Japanese JES IHHI ATD-X, S-Korean JES KF-X. Cf. X-44 in Figure 5. Consequently, the jet engine is no longer defined as providing only brute force forward. Instead, it successfully competes with and wins over the wrong, dominating AOOF-Control, at least as a backup flight control whose sole factual domain is currently a well-established, primary flight

    In an age beset by social and political revolutions, the Green Revolution deals with the most basic of human needs and offers scope for better balance between the growing population and its food requirements. This report takes a close look at how nuclear techniques are being utilized in modern agricultural research to augment the Green Revolution. The Green Revolution is basically the growing of new, higher yielding cereal varieties, particularly wheat and rice, in the developing countries of Asia and Latin America. Many of the new varieties were developed by plant breeders in the Philippines, the United States of America and in Mexico, among whom is Norman Borlaug, who was recently awarded die Nobel Peace Prize for his work. This report deals only with the additional scientific contribution that nuclear techniques are making and can make to sustain and expand the Green Revolution. In this sense it complements other reports dealing with the contributions of the non-nuclear techniques, which are primarily responsible for the Green Revolution.

    One of the most pressing environmental concerns related to wind project development is the potential for avian fatalities caused by the turbines. The goal of this project is to develop a useful, practical modeling framework for evaluating potential wind power plant impacts that can be generalized to most bird species. This modeling framework could be used to get a preliminary understanding of the likelihood of significant impacts to birds, in a cost-effective way. The authors accomplish this by (1) reviewing the major factors that can influence the persistence of a wild population; (2) briefly reviewing various models that can aid in estimating population status and trend, including methods of evaluating model structure and performance; (3) reviewing survivorship and population projections; and (4) developing a framework for using models to evaluate the potential impacts of wind development on birds.

    Taenia solium is a cestode parasitic of humans and pigs that strongly impacts on public health in developing countries. Its larvae (cysticercus) lodge in the brain, causing neurocysticercosis, and in other tissues, like skeletal muscle and subcutaneous space, causing extraneuronal cysticercosis. Prevalences of these two clinical manifestations vary greatly among continents. Also, neurocysticercosis may be clinically heterogeneous, ranging from asymptomatic forms to severely incapacitating and even fatal presentation. Further, vaccine design and diagnosis technology have met with difficulties in sensitivity, specificity and reproducibility. Parasite diversity underlying clinical heterogeneity and technological difficulties is little explored. Here, T. solium genetic population structure and diversity was studied by way of random amplified polymorphic DNA in individual cysticerci collected from pigs in Madagascar and two regions in Mexico. The amplification profiles of T. solium were also compared with those of the murine cysticercus Taenia crassiceps (ORF strain). We show significant genetic differentiation between Madagascar and Mexico and between regions in Mexico, but less so between cysticerci from different localities in Mexico and none between cysticerci from different tissues from the same pig. We also found restricted genetic variability within populations and gene flow was estimated to be low between populations. Thus, genetic differentiation of T. solium suggests that different evolutionary paths have been taken and provides support for its involvement in the differential tissue distribution of cysticerci and varying degrees of severity of the disease. It may also explain difficulties in the development of vaccines and tools for immunodiagnosis.

    As this century draws to a close, spectacular advances in the fields of genomics and genetics are opening up dramatic new horizons for medicine. For much of the 20th century, genetic research has focused on rare diseases caused by mutations in a particular gene. However, more recently it has been realised that common genetic variations (polymorphisms), interacting with the environment, can influence an individual's susceptibility to diseases widely represented in our populations (e.g. mental illness and asthma), redefining the term "genetic disease". Officially starting in 1990, the Human Genome Project was a $3-billion, 15-year program to find the estimated 80,000 human genes and determine the sequence of the 3 billion DNA building blocks that underlie all of human biology and its diversity. The resulting boom in genetic information and technologies, not only from humans, but from many other organisms, means that we now have new tools to understand and treat normal and disease states.

Mushroom can serve as food, tonic, and as medicine thus make people healthier, fitter and happier. They have a cracking potential for generating great socioeconomic impact in human welfare at local, national and international level. With the help of allied mushroom farming we can easily tackle the problem of food for growing world population; reduce environmental pollution by bioconversion of huge organic wastes into mushrooms; recycle huge quantity of organic wastes to mushroom crops, biofertilizers, and biogas; restore damaged environment by mushroom mycelia through mycoforestry, mycoremediation, mycofiltration and mycopesticides in a zero emission fashion. They can be used to degrade radioactive industrial biocide wastes in an eco-friendly fashion. Since mushroom cultivation is an indoor agribusiness, it could have great economic impact by generating employment, income and functional food requirements for rural people especially in developing countries. How far mushroom cultivation can meet the functional food requirements; address the domestic food challenges, rising food prices and crisis vis a vis environmental sustainability will be thrust areas of this communication.

    2012-01-01

    After 20 years at different positions in the gas sector, from the policy side to trading floors, the author gives an overview of the major gas issues and elaborate on the consequences of the US shale gas revolution. The first part of the book provides basic knowledge and gives needed tools to better understand this industry, that often stands, in sandwich, between upstream oil and utilities. After extensive research, publication and teaching, the author shares his insights on fundamental issues all along the gas chain and explains the price mechanisms ranging from oil-indexing to spot. The second part looks into the future of worldwide gas balance. To supply growing markets, the major resource holder, Russia, is now in direct competition with the major gas producer, the US. China has the potential not only to select the winner but also to decide the pricing principle for all Asian buyers in 2020. As China is a new and growing gas importer and has a lower price tolerance than historical Asian buyers (Japan and South Korea), it is highly possible that, against basic geography, China selects waterborne US LNG vs. close Russian pipe gas, to achieve lower import price. Europe, so risk adverse that it won't be able to take any decision regarding shale gas production on this side of 2020, should see its power fading on the energy scene and would rely more on Russia. Gas geopolitics could tighten Russia stronghold on Europe, on one side, and create a flourishing North America-Asian trade... This book is accessible to all and will particularly interest readers seeking a global gas perspective where economics and geopolitics mix. It can be read as an economic novel where billions of $ are invested to shape tomorrow energy world or as a geopolitical thriller where Russia and the US compete to impose their respective agenda, leaving China to select the winner.

    Full Text Available With an estimated 38 million people worldwide currently infected with human immunodeficiency virus (HIV, and an additional 4.1 million people becoming infected each year, it is important to understand how this virus mutates and develops resistance in order to design successful therapies.We report a novel experimental method for amplifying full-length HIV genomes without the use of sequence-specific primers for high throughput DNA sequencing, followed by assembly of full length viral genome sequences from the resulting large dataset. Illumina was chosen for sequencing due to its ability to provide greater coverage of the HIV genome compared to prior methods, allowing for more comprehensive characterization of the heterogeneity present in the HIV samples analyzed. Our novel amplification method in combination with Illumina sequencing was used to analyze two HIV populations: a homogenous HIV population based on the canonical NL4-3 strain and a heterogeneous viral population obtained from a HIV patient's infected T cells. In addition, the resulting sequence was analyzed using a new computational approach to obtain a consensus sequence and several metrics of diversity.This study demonstrates how a lower bias amplification method in combination with next generation DNA sequencing provides in-depth, complete coverage of the HIV genome, enabling a stronger characterization of the quasispecies present in a clinically relevant HIV population as well as future study of how HIV mutates in response to a selective pressure.

The rehabilitation is most important direction of medical sector supporting complex of services in closed cycle of rendering medical care to population and significant social economic effects. The capacity and extreme unprofitability of rehabilitation services determine necessity of searching alternative forms of organization of this type of care and financing including mechanisms of public-private partnership. The experience is presented related to involvement of resources of non-public medical organizations for implementing public commitments on rendering qualitative rehabilitation services to population using innovative medical organizational technologies.

  1. The Fastskin Revolution From Human Fish to Swimming Androids

    Directory of Open Access Journals (Sweden)

    Jennifer Craik

    2011-04-01

    Full Text Available The story of fastskin swimsuits reflects some of the challenges facing the impact of technology in postmodern culture. Introduced in 1999 and ratified for the Sydney 2000 Olympic Games, fastskin swimsuits were touted as revolutionising competitive swimming. Ten years later, they were banned by the world’s swimming regulatory body FINA (the Fédération Internationale de Natation, with the ban taking effect from January 2010 (Shipley 2009. The reason was the controversy caused by the large number of world records that were broken by competitors wearing polyurethane swimsuits, the next generation of the original fast skin suits. These suits were deemed to be providing an artificial advantage by increasing buoyancy and reducing drag. This had been an issue ever since they were introduced, yet FINA had approved the suits and, thereby, unleashed an unstoppable technological revolution of the sport of competitive swimming. Underlying this was the issue about its implications of the transformation of a sport based on the movement of the human body through water without the aid of artificial devices or apparatus. This article argues that the advent of the fastskin has not only transformed the art of swimming but has created a new image of the swimmer as a virtual android rather than a human fish. In turn, the image of the sport of swimming has been re-mapped as a technical artefact and sci-fi spectacle based on a radically transformed concept of the swimming body as a material object that has implications for the ideal of the fashionable body.

    Whether or not scholarly publications are going through an evolution or revolution, one comforting certainty remains: the NASA Astrophysics Data System (ADS) is here to help the working astronomer and librarian navigate through the increasingly complex communication environment we find ourselves in. Born as a bibliographic database, today's ADS is best described as a an "aggregator" of scholarly resources relevant to the needs of researchers in astronomy and physics. In addition to indexing content from a variety of publishers, data and software archives, the ADS enriches its records by text-mining and indexing the full-text articles, enriching its metadata through the extraction of citations and acknowledgments and the ingest of bibliographies and data links maintained by astronomy institutions and data archives. In addition, ADS generates and maintains citation and co-readership networks to support discovery and bibliometric analysis.In this talk I will summarize new and ongoing curation activities and technology developments of the ADS in the face of the ever-changing world of scholarly publishing and the trends in information-sharing behavior of astronomers. Recent curation efforts include the indexing of non-standard scholarly content (such as software packages, IVOA documents and standards, and NASA award proposals); the indexing of additional content (full-text of articles, acknowledgments, affiliations, ORCID ids); and enhanced support for bibliographic groups and data links. Recent technology developments include a new Application Programming Interface which provides access to a variety of ADS microservices, a new user interface featuring a variety of visualizations and bibliometric analysis, and integration with ORCID services to support paper claiming.

  3. Water Intelligence and the Cyber-Infrastructure Revolution

    Science.gov (United States)

    Cline, D. W.

    2015-12-01

    As an intrinsic factor in national security, the global economy, food and energy production, and human and ecological health, fresh water resources are increasingly being considered by an ever-widening array of stakeholders. The U.S. intelligence community has identified water as a key factor in the Nation's security risk profile. Water industries are growing rapidly, and seek to revolutionize the role of water in the global economy, making water an economic value rather than a limitation on operations. Recent increased focus on the complex interrelationships and interdependencies between water, food, and energy signal a renewed effort to move towards integrated water resource management. Throughout all of this, hydrologic extremes continue to wreak havoc on communities and regions around the world, in some cases threatening long-term economic stability. This increased attention on water coincides with the "second IT revolution" of cyber-infrastructure (CI). The CI concept is a convergence of technology, data, applications and human resources, all coalescing into a tightly integrated global grid of computing, information, networking and sensor resources, and ultimately serving as an engine of change for collaboration, education and scientific discovery and innovation. In the water arena, we have unprecedented opportunities to apply the CI concept to help address complex water challenges and shape the future world of water resources - on both science and socio-economic application fronts. Providing actionable local "water intelligence" nationally or globally is now becoming feasible through high-performance computing, data technologies, and advanced hydrologic modeling. Further development on all of these fronts appears likely and will help advance this much-needed capability. Lagging behind are water observation systems, especially in situ networks, which need significant innovation to keep pace with and help fuel rapid advancements in water intelligence.

  4. Rethinking the Role of Grey Literature in the Fourth Industrial Revolution

    International Nuclear Information System (INIS)

    Savić, Dobrica

    2018-01-01

    The world is at the dawn of a new industrial revolution that will fundamentally change the way we live and work. Many consider this the Fourth Industrial Revolution (4IR). While the First Industrial Revolution (1IR) mechanized production using water and steam power, the second one brought mass production using electric power, and the third one was characterized by automation and digitization, mainly using electronics and information technology. The 4IR is building upon the third one, but the difference, and its main contribution, is the fusion of technologies that are blurring the lines between the physical, digital, and biological worlds. This is further enhanced by the emerging progress of technology in fields such as quantum computing, machine learning, artificial intelligence, robotics, virtual assistants, the Internet of Things, self-driving cars, drones, 3-D printing, nanotechnology, biotechnology, traffic and security monitoring systems, and renewable energy. This paper examines the potential impact of the emerging 4IR on grey literature (GL) and is based on analysis of the most prevalent current trends and developments in “cyber-physical systems” that connect machines, computers and people. It will examine the need to rethink the definition of GL, its creation and publication types, processing, sustainability and usability. Given the magnitude of the potential impact of the 4IR on GL, the question is what challenges the 4IR will pose to GL managers. One could assume that the acquisition of new knowledge and skills, and the revamping of existing processes and methods will be necessary. Becoming aware of this new phenomenon is only the beginning. It needs to be followed up by professional development and adequate training. Finally, the job of GL professionals will be to promote and publicize the usefulness and importance of GL, not only in their daily work, but also in research and science. (author)

  5. Online Community Interaction - Revolution or Revulsion?

    Directory of Open Access Journals (Sweden)

    Justin Thorne

    2008-02-01

    Full Text Available Marketing writers' assertion that online communities are the future for organisations may be misguided, although peer-to-peer networks are certainly the future for consumers. Brands have experienced 'consumer revulsion' at their poorly-planned attempts to enter online communities to interact with customers. The Internet has facilitated a revolution amongst consumers, providing a medium for online communities to thrive. Source credibility is paramount and Internet users are being selective with exactly whose message they are willing to accept, absorb and ultimately, allow to influence their buying decisions. The primary objective of this research is to undertake an exploratory investigation into the dynamics of online communities and how membership influences the buying decision for consumers of genre novels. Through the process of online focus groups and the completion of online questionnaires, data on the dynamics of online relationships between consumers and authors, the buying habits of consumers and the acceptance of online word-of-mouth (WOM were extracted and analysed. This research demonstrates that the dynamics of online communities are highly complex and in no way inferior or less fulfilling than real-life relationships and that the influence of online relationships on our buying decisions have no less impact than real-life encounters.

  6. [Pierre Bourdieu: sociology as a "symbolic revolution"].

    Science.gov (United States)

    Suaud, Charles

    2014-03-01

    The article combines two objectives: understand the genesis and development of the sociology of Bourdieu in connection with his social and intellectual positioning. The sociology of Bourdieu is a theory of Action which reconciles the double requirement of objectification and taking account of the practical logic bound by social agents. From the character both objective and subjective of social space, he analyzes how different institutions (firstly School) are doing that mental structures match the objective structures of society. By making acceptable reality and registering it in the body, these instances contribute to reproduce social divisions and participate in the work of domination. Gradually, Bourdieu develops a general theory about Power, which leads to a sociology of State. But he refuses any sociological fatalism. Because he perceived homologies between the sociologist and the artist facing the social order, each in their own way, he devoted two researches to Flaubert and Manet, seized in the same enterprise of aesthetic subversion he described as a 'symbolic revolution'. In many aspects, the sociology of Bourdieu opens ways of looking for an objectification of caregivers and their practices.

    The observed diversity of dinosaurs reached its highest peak during the mid- and Late Cretaceous, the 50 Myr that preceded their extinction, and yet this explosion of dinosaur diversity may be explained largely by sampling bias. It has long been debated whether dinosaurs were part of the Cretaceous Terrestrial Revolution (KTR), from 125–80 Myr ago, when flowering plants, herbivorous and social insects, squamates, birds and mammals all underwent a rapid expansion. Although an apparent explosion of dinosaur diversity occurred in the mid-Cretaceous, coinciding with the emergence of new groups (e.g. neoceratopsians, ankylosaurid ankylosaurs, hadrosaurids and pachycephalosaurs), results from the first quantitative study of diversification applied to a new supertree of dinosaurs show that this apparent burst in dinosaurian diversity in the last 18 Myr of the Cretaceous is a sampling artefact. Indeed, major diversification shifts occurred largely in the first one-third of the group's history. Despite the appearance of new clades of medium to large herbivores and carnivores later in dinosaur history, these new originations do not correspond to significant diversification shifts. Instead, the overall geometry of the Cretaceous part of the dinosaur tree does not depart from the null hypothesis of an equal rates model of lineage branching. Furthermore, we conclude that dinosaurs did not experience a progressive decline at the end of the Cretaceous, nor was their evolution driven directly by the KTR. PMID:18647715

    2012-01-01

    The year 2012 marks the 50th anniversary of the publication of Thomas S. Kuhn's The Structure of Scientific Revolutions. Up until recently, the book's philosophical reception has been shaped, for the most part, by the debates and the climate in philosophy of science in the 1960s and 1970s; this new collection of essays takes a renewed look at this work. This volume concentrates on particular issues addressed or raised in light of recent scholarship and without the pressure of the immediate concerns scholars had at the time of the Structure's publication. There has been extensive research on all of the major issues concerning the development of science which are discussed in Structure, work in which the scholars contributing to this volume have all been actively involved. In recent years they have pursued novel research on a number of topics relevant to Structure's concerns, such as the nature and function of concepts, the complexity of logical positivism and its legacy, the relation of history to philosophy o...

  9. Engineering with nuclear explosives near populated areas - A survey from the technological and economic viewpoint

    International Nuclear Information System (INIS)

    Parker, K.

    1970-01-01

    Current experience with underground firings of nuclear explosives and of large charges of conventional explosives is largely confined to sparsely populated areas such as the Nevada and Sahara deserts and parts of Siberia. On the other hand many of the commercial applications proposed for nuclear explosives are directly relevant to industrialized areas, where consumptions of energy and natural resources are high, as are population densities. In many of these areas there is a need to increase the efficiency with which natural gas, oil and electrical power are supplied and to make safe disposal of fluid wastes; completely contained nuclear explosions could be a useful tool in achieving some or all of these aims. Whilst radioactivity and air blast hazards are likely to rule out nuclear cratering operations near densely populated areas, the prospects for carrying out completely contained explosions are much better, providing seismic damage is kept within reasonable bounds. In large areas of Western Europe and on the eastern, southern and western seaboards of the United States this might be achieved by using nuclear explosions beneath the seabed at a reasonable distance from the nearest coastline, always provided the relevant political issues can be resolved. Stimulation and storage of North Sea natural gas, construction of off-shore oil storage and storage of electrical energy are areas where engineering with nuclear explosives merits more detailed investigation and some of the relevant technical problems are discussed.

    The introduction of technically-advanced imaging systems in medicine carries with it potential health hazards, particularly from ionizing and nonionizing radiation exposure of human populations. This paper will discuss what we know and what we do not know about the health effects of low-level radiation, how the risks of radiation-induced health effects may be estimated, the sources of the scientific data, the dose-response models used, the uncertainties which limit precision of estimation of excess health risks from low-level radiation, and what the implications might be for radiation protection in medicine and public health policy

    Changizi, Maryam; Kaveh, Mohammad H

    2017-01-01

    Demographic changes in the 21st century, increased population of the elderly and high prevalence of related diseases call for new healthcare strategies that can change the behavior and lifestyle of elderly individuals. Innovative information and communication technology, such as mobile health (mHealth), can play a significant role. The present study was conducted aiming to assess the effectiveness of mHealth in improving health behaviors among an elderly population. This paper presents a systematic review involving a search of PubMed, Web of Science (ISI), Scopus, Science Direct and Embase databases from [2012-2016]. Our search resulted after initial evaluations 12 articles. Inclusion criteria mostly revolved around interventional studies, other studies were excluded because of their methodology, non-elderly target groups and irrelevant to the subject. Findings showed that mHealth can improve care, self-management, self-efficacy, behavior promotion (quality of sleep, diet, physical activity mental health) and medication adherence. The mHealth technology has proven effective for disease prevention, lifestyle changes, management of cardiovascular disease and diabetes, and is a suitable tool for elderly people. In conclusion, it seems that mHealth can facilitate behavioral changes; although, further research is necessary in this regard.

    2017-01-01

    In Portugal, Spain, and South Africa, there has been a noted anti-neoliberal resistance, marked by the significant participation of the older generation in protest movements. Changing demographics, the global financial crisis, unemployment, poverty, and the reliance of the family nucleus on the pensioner, coupled with neoliberal and austerity-based reductions to welfare programs, pensions, health, and social care, has caused the "silver revolution." As a population group that is often considered to be less politically active and robust members of society, such resistance is a noteworthy moment in society that needs to be considered and responded to.

    2013-11-15

    The purpose of this study was to quantify the reduction in patient radiation dose by X-ray imaging technology using image noise reduction and system settings for neuroangiography and to assess its impact on the working habits of the physician. Radiation dose data from 190 neuroangiographies and 112 interventional neuroprocedures performed with state-of-the-art image processing and reference system settings were collected for the period January-June 2010. The system was then configured with extra image noise reduction algorithms and system settings, which enabled radiation dose reduction without loss of image quality. Radiation dose data from 174 neuroangiographies and 138 interventional neuroprocedures were collected for the period January-June 2012. Procedures were classified as diagnostic or interventional. Patient radiation exposure was quantified using cumulative dose area product and cumulative air kerma. Impact on working habits of the physician was quantified using fluoroscopy time and number of digital subtraction angiography (DSA) images. The optimized system settings provided significant reduction in dose indicators versus reference system settings (p<0.001): from 124 to 47 Gy cm{sup 2} and from 0.78 to 0.27 Gy for neuroangiography, and from 328 to 109 Gy cm{sup 2} and from 2.71 to 0.89 Gy for interventional neuroradiology. Differences were not significant between the two systems with regard to fluoroscopy time or number of DSA images. X-ray imaging technology using an image noise reduction algorithm and system settings provided approximately 60% radiation dose reduction in neuroangiography and interventional neuroradiology, without affecting the working habits of the physician.

    Full Text Available Turkey's foreign policy has been drawing considerable attention particularly because of the momentous transformations in the Middle East. The visits of Turkish Prime Minister Recep Tayyip Erdogan and Foreign Minister Ahmet Davuoglu to Egypt, Libya, and Tunisia in September 2011 and their subsequent visits to the region underscored the rise of Turkey's involvement in the region. The Arab Spring came at a time when Turkey's relations with the United States, Israel and the European Union were going through significant turbulence. 2010 proved to be a particularly difficult year for Turkey's place in the transatlantic community. The Gaza flotilla crisis in June 2010 - ending with Israeli forces killing eight Turkish citizens - and Turkey's "no" vote to a new round of sanctions against Iran at the United Nations (UN Security Council that same month triggered a heated debate on Turkey's relations with the West, which led popular American columnists such as Tom Friedman to go as far as arguing that Ankara was now joining the "Hamas- Hezbollah-Iran resistance front against Israel." While this was a clear exaggeration, it indicated the scope of debate on the eve of the Arab Spring. Since the Arab Spring, the Western discourse about Turkey has dramatically changed. Instead of asking "who lost Turkey" or complaining about the Islamization of Turkish foreign policy, analysts began discussing whether the new regimes in the Arab world would follow the "Turkish model." This article aims to analyze the Turkish approach to the Middle East and the Arab revolutions, the main determinants of Turkish foreign policy and diplomacy in the Middle East and the debate on "Turkish Model. What has changed, or has not, during and after the Arab Spring?

  17. Energy transition. Between reform and revolution

    Laville, Bettina

    2014-07-01

    The author comments the content of the French bill project on energy transition. She first discusses the meaning of this concept of energy transition which can be perceived as an evolution, a transformation, a progressive change, rather than a revolution. She recalls the original debate between those who wanted to preserve nuclear energy because it does not produce CO 2 emissions, and those who wanted a more radical change of the energy system. In this respect, she outlines and comments the main statements made by the French President on these issues, and indicates the main measures defined in the bill project regarding the reduction of greenhouse gas emission, the increase of the share of renewable energies, a decrease of the share of nuclear in power production, and a reduction of energy consumption. Then, she discusses how this transition is to be financed, proposes an assessment and a discussion of the skills and shortcomings of the bill project. She notably states that the main shortcoming is the lack of strong objectives regarding the reduction of emissions by transports, and the development of inter-modality. She also regrets the disappearance of the regional public service of energy efficiency, the fact that electricity consumption is not capped. Because of that, it's not that sure that the reduction of greenhouse gas emission by a factor 4 in 2050 with respect to 1990 will be reached. In the next parts, the author discusses the issue of the ecologic tax policy, outlines the importance of being exemplary within the perspective of the 2015 Conference on Climate (COP21)

  18. Tunisia’s Revolution and Youth Unemployment

    2013-11-01

    Full Text Available Youth joblessness was one of the main triggers of Tunisia’s January Revolution. Unemployment rate in Tunisia has increased from 13 percent in 2010 to 18.3 percent in 2011 (NIS, 2011. Young people and women are more affected by this increase in unemployment .Thus, the purpose of this study is to examine the effects of various individual and job-related characteristics on the probabilities of unemployment of females and males aged 15–29 and to explore policy actions to create jobs in Tunisia. These issues are addressed using data from a 2010 survey of the National Institute of Statistics that provided information on the employment status of youth aged 15–29. The main estimated results show first that individual’s age, gender, marital status, level of education, sector of economic activity, type of employment and region of residence are significantly related to the unemployment. The results indicate that, for young workers, unemployment incidence increases with the level of education. Education has a greater impact on the unemployment of females than on that of males. Second, there is a negative and significant effect of the agricultural, educational and health sectors on the probability of transition into unemployment for women and men in which case the estimated impact is greater for men. Third, coastal area and public employment are associated with lower probability of transition into unemployment. Finally, Tunisian policymakers are aware of the fact that the elected National Constituent Assembly and the transitional government have a set of challenging tasks to accomplish in order to lower the rate of youth unemployment. For instance, generating funds for business development and infrastructure in non-coastal regions, and collaborating with the private sector to promote investment– whether foreign or domestic – and employment for educated young people.

  20. Hot, flat and crowded. Why we need a green revolution - and how it can renew America

    International Nuclear Information System (INIS)

    Friedman, T.L.

    2009-01-01

    The author blows the whistle about what he considers as a worldwide environmental crisis. He brings a fresh outlook to the crises of destabilizing climate change and rising competition for energy - both of which could poison our world if we do not act quickly and collectively. His argument speaks to all of us who are concerned about the state of America in the global future. The author proposes that an ambitious national strategy - which he calls 'Geo-Greenism' - is not only what we need to save the planet from overheating; it is what we need to make America healthier, richer, more innovative, more productive, and more secure. He explains a new era - the Energy-Climate era - through an illuminating account of recent events. He shows how 9/11, Hurricane Katrina, and the flattening of the world by the Internet (which brought 3 billion new consumers onto the world stage) have combined to bring climate and energy issues to Main Street. But they have not gone very far down Main Street; the much-touted 'green revolution' has hardly begun. With all that in mind, the author sets out the clean-technology breakthroughs we, and the world, will need; he shows that the energy technology revolution will be both transformative and disruptive; and he explains why America must lead this revolution - with the first Green President and a Green New Deal, spurred by the Greenest Generation. This book is fearless, incisive, forward-looking, and rich in surprising common sense about the world we live in today

These physician´s offices were selected by a conglomerate sampling and a random stratified sample was taken from each office. The stratification variable was the age of the studied persons. The selection of each stratum was based on a fixed index proportional to the size of each age group, therefore the final sample was the following: 0-4 years age group =278; 5-11 age group =311; 12-14 =215; 15-34 ? 1 089; 35-59 _ 1 209 and 60 years and over group = 836 inhabitants. Skin and mucose alterations were not oral health problems. ATM condition was good; these disorders were not significant in the studied population, although there are significant differences among the age groups. As to dental caries, CEO was low in primary dentition whereas COP is high in permanent dentition, all depending on the number of obturations and lost teeth. The behavior of malocclusion is favorable, with predominance of slight types. Periodontal disease prevails in 35-59 y age group, with significant differences among the groups. All the studied problems increase with the age. Regarding assistance requirements, primary care was predominant from the orthodontic viewpoint whereas secondary care requirements were higher in the management of periodontal diseases. The most affected group was the 35-59 years in prosthetic treatment, but differences were significant among the age groups. On the other hand, requirements for treatment

    Full Text Available Purpose. To determine the repeatability of recalculated corneal visualization Scheimpflug technology (CorVis ST parameters and to study the variation of biomechanical properties and their association with demographic and ocular characteristics. Methods. A total of 783 healthy subjects were included in this study. Comprehensive ophthalmological examinations were conducted. The repeatability of the recalculated biomechanical parameters with 90 subjects was assessed by the coefficient of variation (CV and intraclass correlation coefficient (ICC. Univariate and multivariate linear regression models were used to identify demographic and ocular factors. Results. The repeatability of the central corneal thickness (CCT, deformation amplitude (DA, and first/second applanation time (A1/A2-time exhibited excellent repeatability (CV% ≤ 3.312% and ICC ≥ 0.929 for all measurements. The velocity in/out (Vin/out, highest concavity- (HC- radius, peak distance (PD, and DA showed a normal distribution. Univariate linear regression showed a statistically significant correlation between Vin, Vout, DA, PD, and HC-radius and IOP, CCT, and corneal volume, respectively. Multivariate analysis showed that IOP and CCT were negatively correlated with Vin, DA, and PD, while there was a positive correlation between Vout and HC-radius. Conclusion. The ICCs of the recalculated parameters, CCT, DA, A1-time, and A2-time, exhibited excellent repeatability. IOP, CCT, and corneal volume significantly influenced the biomechanical properties of the eye.

    To examine the relationships among Assistive Technology (AT) use, race, type of disability and selected other demographic characteristics. Using 2009 National Health Interview Survey, descriptive statistics, statistical interactions and binary logistic regression were performed to identify, contrast and predict the likelihood of using AT based on the type of disability among African Americans (AAs) and European Americans (EAs). We found that more AAs (10% within group proportion of total AAs) used AT compared to EAs (7.5% within group proportion of total EAs). Physical (p disabling conditions that predict the use of AT than AAs, whereas AAs had more demographic characteristics beyond race that predict AT use than EAs. Disparities were observed in AT usage by disability types and demographic characteristics between AAs and EAs. Moreover, the predictive strength of AT usage based on disability types and other demographic variables differed by races. Overall, the findings about the different relationships among race, disability type, and AT use are found. Implications for Rehabilitation The finding may inform the development of initiatives by rehabilitation leaders to encourage the use of AT by AAs and EAs according to their type of impairment. Having identified physical impairment as statistically significant predictor of AT use greater among AAs, rehabilitation leaders should ensure that people living with those types of disability have access to the corresponding type of AT and can use them effectively.

    Western development models label subsistence economies, which do not participate in the market economy on a grand scale and do not consume commodities produced for and distributed through the market, to be poor. Yet, subsistence does not always indicate a low quality of life. The Western development process has destroyed wholesome and sustainable lifestyles. In India, the Green Revolution caused many small farmers to lose their land. In comparison to traditional economies, industrial economies have longer technological chains dependent on higher energy and resource inputs and exclude large numbers of people without power to buy goods. Further, they generate new and artificial needs, necessitating increased production of industrial goods and services. They erode resource bases for survival. This erosion is marginalizing people who were traditionally in nature's economy. Developed countries did not deliver 0.15% of their GNP to development projects in developing countries as promised. The US made population growth in these countries its cause. The UN and other multinational agencies during 1962-1972, at the US's request, began to support population and family planning programs in developing countries. These countries opposed the 1st draft at the 1974 Bucharest Population Conference, but by the conference in Mexico City, most supported the need for family planning. Yet, the US politicized this conference and had a greater say in the recommendations than did developing countries. Structural adjustments and external debt repayments required of developing countries in the 1980s set them back. In fact, the number of developing countries increased from 31 to 42. The UN recognizes the right to development, but social inequalities are barriers to this right. If environmental degradation continues, poverty will only increase. Women's groups are playing a great role in preparations for the International Conference on Population and Development in Cairo in September 1994.

  10. Serbian Volunteers And Russian Revolution Of 1917

    Ia. V. Vishniakov

    2017-01-01

    Full Text Available Using original documents from the Russian State Military Historical Archive, many of which are introduced for the first time, the author reveals details of creation and activities of the Serbian Volunteer Corps formed from captured soldiers and officers of the Austro-Hungarian army inOdessain the Summer 1916. The same autumn it received a baptism of fire in Dobruja fighting in the separate corps of the Russian army under the command of General Zayonchkovsky. The research interest in studying the activities of “national” and "international" military units within the Russian army is connected with the question of expediency and effectiveness of using such forces against those for whom they have not so long ago shed blood. The author, contrary to the popular opinion of Serbian historians, shows that the call to join the First Serbian division did not arouse mass enthusiasm among the prisoners of war both Serbs and representatives of other Yugoslav nations because of well-founded fears for their close relatives living in the Dual Monarchy and a fairly comfortable stay in the Russian captivity. At the same time, the author emphasizes that this military unit, commanded by officers of the Serbian regular army, was considered by the political leadership ofSerbiaas the basis of the future armed forces of the new state ofYugoslavia. The article shows that the events of the Russian Revolution of 1917 influenced the future fate of this military formation. Many of its soldiers later found themselves on different sides of the front in the Russian civil war. A special attention is payed to the interethnic conflict erupted in the corps between the Serbs on the one side and the Croats and Slovenes on the other. The author introduces a significant body of primary documents showing the nuances of relations in the corps between representatives of various Yugoslav nations. The article emphasizes that the relationship of the Serbs, Croats and Slovenes within the

    Materials have played a central role during all advances in human civilization as far back as recorded histories exist. It is possible to characterize the application of materials in technologies as three distinct eras. In the first era, during the industrial revolution materials were mainly used for structural and functional applications. In the second era which includes the information technology revolution, material properties were exploited by integrating them in structures and combining different materials in a systematic manner. In the next era, we indicate that materials application will enter the next era in which size will be used to design materials with targeted properties. In this, for the advent of so-called ``smart'' materials, nano dimensions (between atomic and macrostructures) where both properties and synthesis will lead to may new applications, where differences between devices and materials will disappear. ``Nanomaterials'' will have newer properties because of many new phases the ability to manufacture the using nanotechnology. However, this will also pose challenges in terms of modeling and characterization given the complex nature of the materials and also due to increasing effects of interfaces of these materials. We will outline with examples from multiple industries. Co-authors: E. Kaxiras, J. Grossman.

  14. Do Digital Social Networks Foster Civilian Partecipation among Millenials? Kitchenware Revolution and 15M Democratic Regeneration Cases

    Directory of Open Access Journals (Sweden)

    Igor Calzada

    2018-02-01

    Full Text Available Nowadays “education for citizenship” is presented as a solution for many of the political, social, and co-existential issues in Western democratic societies in order to tackle dysfunctionalities produced by globalization, populism, migration, information and communication technologies (ICTs, and violence. At the same time, particularly among “millennials” or “digital natives”, lack of civil commitment and apathy toward politics as a whole contrasts with their intensive usage of digital social networks, or social media. By examining in-depth the scientific literature about the potential conceptual correlations between the use of “digital social networks” and civilian participation among “millennials”, this paper explores two widely studied paradigmatic events of democratic regeneration: the “Kitchenware Revolution” in Iceland after the financial collapse on 6 October 2008, and the “15M Movement” in Spain after 15 May 2011. Despite the substantial relevance that digital social networks played in both cases, this paper wonders to what extent digital social networks foster millennials’ civilian participation, when, paradoxically, they seem to be the population target who contests the status quo but who is not actually being represented democratically in the formal political system. The author concludes that digital social networks could initially foster civilian participation, but they should be seen as a new artefact that, itself, does not necessarily lead to a better political representation of millennials. As well, this paper argues against the widespread assumption regarding the correlation between socioeconomic and educational status and Internet usage factors of millennials when it comes to civilian participation, particularly in extreme political mobilisation events such as the Kitchenware Revolution and 15M.

    Dies ist die Geschichte von Einsteins unvollendeter Revolution, einer tiefgreifenden Veränderung unserer Begriffe von Raum, Zeit, Materie und Strahlung. Diese Revolution begann in Einsteins Wunderjahr 1905, wurde durch seine allgemeine Relativitätstheorie aus dem Jahre 1915 fortgesetzt und wirkt in den heutigen Versuchen der Wissenschaft, die Entstehung und das Schicksal des Universums zu verstehen, weiter. Vor dem Hintergrund einer historischen Theorie des wissenschaftlichen Fortschritts wird Einsteins bis heute nicht abgeschlossene Revolution als das Ergebnis einer langfristigen Entwicklung des Wissens verständlich. Anhand der spannenden Geschichte von Einsteins Entdeckungen wird nachvollziehbar, warum große Denker wie Einstein weiter gesehen haben als ihre Vorgänger. Sie standen nicht nur auf den Schultern von Riesen, also den wissenschaftlichen Leistungen einzelner großer Vorgänger wie Newton, sondern auch auf den Schultern von "Zwergen", dem wissenschaftlichen Wissen, dem technischen Wissen, und d...

    2014-06-01

    The aim of the paper is to clarify Kuhn's theory of scientific revolutions. We propose to discriminate between a scientific revolution, which is a sociological event of a change of attitude of the scientific community with respect to a particular theory, and an epistemic rupture, which is a linguistic fact consisting of a discontinuity in the linguistic framework in which this theory is formulated. We propose a classification of epistemic ruptures into four types. In the paper, each of these types of epistemic ruptures is illustrated by examples from physics. The classification of epistemic ruptures can be used as a basis for a classification of scientific revolutions and thus for a refinement of our view of the progress of science.

    Humans have always sought to imitate the human appearance, functions and intelligence. Human-like robots, which for many years have been a science fiction, are increasingly becoming an engineering reality resulting from the many advances in biologically inspired technologies. These biomimetic technologies include artificial intelligence, artificial vision and hearing as well as artificial muscles, also known as electroactive polymers (EAP). Robots, such as the vacuum cleaner Rumba and the robotic lawnmower, that don't have human shape, are already finding growing use in homes worldwide. As opposed to other human-made machines and devices, this technology raises also various questions and concerns and they need to be addressed as the technology advances. These include the need to prevent accidents, deliberate harm, or their use in crime. In this paper the state-of-the-art of the ultimate goal of biomimetics, the development of humanlike robots, the potentials and the challenges are reviewed.

The Saint Louis University Mental State examination (SLUMS) was ported onto a computerized mobile application named the Cambridge University Pen to Digital Equivalence assessment (CUPDE). CUPDE was piloted and compared to the traditional pen and paper version, with a common comparator test for both groups. Sixty healthy participants (aged 50-79) completed both measurements. Differences were tested between overall outcomes, individual items, and relationship with the comparator. Significant differences in the overall scores between the two testing versions as well as within individual items were observed. Even when groups were matched by cognitive function and age, scores on SLUMS original version (M = 19.75, SD = 3) were significantly higher than those on CUPDE (M = 15.88, SD = 3.5), t (15) = 3.02, p Mobile platforms require the development of new normative standards, even when items can be directly translated. Furthermore, these must fit aging populations with significant variance in familiarity with mobile technology. Greater understanding of the interplay and related mechanisms between auditory and visual systems, which are not well understood yet in the context of mobile technologies, is mandatory.

    Mobile phone-based technology has been used in improving the delivery of healthcare services in many countries. However, data on the effects of this technology on improving primary healthcare services in resource-poor settings are limited. The aim of this study is to develop and test a mobile phone-based system to improve health, population and nutrition services in rural Bangladesh and evaluate its impact on service delivery. The study will use a quasi-experimental pre-post design, with intervention and comparison areas. Outcome indicators will include: antenatal care (ANC), delivery care, postnatal care (PNC), neonatal care, expanded programme on immunization (EPI) coverage, and contraceptive prevalence rate (CPR). The study will be conducted over a period of 30 months, using the existing health systems of Bangladesh. The intervention will be implemented through the existing service-delivery personnel at various primary-care levels, such as community clinic, union health and family welfare centre, and upazila health complex. These healthcare providers will be given mobile phones equipped with Apps for sending text and voice messages, along with the use of Internet and device for data-capturing. Training on handling of the Smartphones, data-capturing and monitoring will be given to selected service providers. They will also be trained on inputs, editing, verifying, and monitoring the outcome variables. Mobile phone-based technology has the potential to improve primary healthcare services in low-income countries, like Bangladesh. It is expected that our study will contribute to testing and developing a mobile phone-based intervention to improve the coverage and quality of services. The learning can be used in other similar settings in the low-and middle-income countries.

  4. The superconductor revolutions and the (slow) applications evolution

    The discovery in the 1960's of type 2 superconductors with high critical current densities in high magnetic fields (and the development of NbTi in particular) led to the first revolution. The discovery of high temperature superconductors (HTS) started the second revolution. At this stage ceramists became involved with superconductors. I will assess the status of various superconductor applications, progress of HTS and their possible applications at 4.2K, and near-term needs for superconducting materials operating at 30T in specialized facilities. Reasons for the slow growth of superconductor applications will be reviewed

    A formulation and solution technique are presented for the creep analysis of shells of revolution subjected to arbitrary loads and temperature changes. Arbitrary creep laws are admitted in the formulation with specific attention given to the two common laws, i.e. strain hardening and time hardening. The governing equations for creep of shells of revolution are derived. The solution method requires the quasi-static linearization of the equations: linear incremental behaviour is assumed during each time step. The incremental equations are expanded in Fourier series and solved by a numerical integration technique. (Auth.)

    Patients with chronic conditions are often the most frequent users of health care. Moreover, adapting to developments in one's illness, understanding how to self-manage a chronic illness, and sharing information between primary care and specialty providers, can be a full-time job for someone with a chronic illness. In response to these challenges, Christiana Care Health System (Wilmington, Delaware) developed Care Link, an information technology (IT)-enhanced care management support to enable populations of patients to achieve better clinical outcomes at lower cost. In 2012 Christiana Care received a grant to design a generalizable, scalable, and replicable IT-driven care model that would integrate disparate clinical and registry data generated from routine care to support longitudinal care management for patients with ischemic heart disease. The single-disease care management program was expanded beginning in mid-2015 to serve risk-based models for many diseases and chronic conditions. More than 8,600 patients in several surgical and medical populations, including joint replacement, cervical spine surgery, and congestive heart failure, have been supported by Care Link. For example, preoperative assessment of patients with elective joint replacement to predict post-acute care needs led to an increase in the volume of patients discharged to home with self-care or with home health care by 30%-from 61% to 80%. Care Link IT functions can be replicated to address the unique longitudinal care needs of any population. Care Link's next steps are to continue to increase the number of patients served throughout the region and to expand the scope of care management programming. Copyright © 2017 The Joint Commission.

    The construction of nine high-end technical installations (hereafter Project NGI, for Nine Great Installations or ) in the 1960s and 1970s was an indispensable part of the development of China's defense and heavy industries. The project put more than 1400 machines into operation or trial operation during the Culture Revolution (1966-1976), and they served essential technical functions in sectors such as aviation, aerospace, machinery, metallurgy, and electronics, and directly advancing the development of these fields. It took more than a decade for Project NGI to go from planning to completion-a surprisingly uninterrupted and steady development while China fell into unprecedented turmoil. One important reason for Project NGI's success was the vital leadership of Shen Hong (, 1906-1998), the technical director of the project and a high-ranking official. Supported by state leaders such as Zhou Enlai and Nie Rongzhen, Shen and his colleagues adopted a suitable roadmap for technological development, coordinated the best-performing manufacturing forces in the country, and successfully manufactured the NGI machines. Project NGI is significant for the history of Chinese science, technology, and medicine during the Cultural Revolution not because it was technologically original, but because it represents an extraordinary case, in which the project's technological development seemed to be largely exempted from the interference of the turbulent Cultural Revolution. The project's national defense orientation, its pragmatism, and the contemporary dogma of self-reliance (), in addition to Shen Hong's political maneuvering, all contributed to the creation of a relatively calm and favorable environment around Project NGI. Despite the widespread turmoil in the country, Shen managed to assemble a stable and continuously productive team, which executed experiments, absorbed previously introduced Soviet technologies, stayed informed about advanced European and American technologies

  9. Completing the Revolution? The United States and Bolivia’s Long Revolution

    Full Text Available James Malloy’s 1970 study, still one of the most systematic analytical attempts in English to understand Bolivia’s 1952 National Revolution, argued that the revolution remained “uncompleted.”  However, the election and subsequent policies of the Morales government after 2005 moved Bolivia much closer to completing two important stated objectives of the revolution, as yet unfulfilled when Malloy wrote: inclusion of all Bolivians in the political system and increased national autonomy.  While it is premature to call Bolivia’s revolution “completed,” the shift in the locus of power from Europeanized elites to more broadly popular forces and the growing independence of Bolivia from outside influence and direction under Morales are key achievements of what might be called Bolivia’s “Long Revolution.”   Giving close attention to these two fundamental achievements—inclusion and autonomy—this paper provides a preliminary examination of the complicated and often paradoxical role the United States has played in Bolivia’s long historical trajectory since April 1952.  Directly and indirectly, through imposition and suggestion, purposefully and unintentionally, by providing assistance and at the same time stimulating fierce nationalist resistance, through design and through the twists and turns of historical contingency—the United States has contributed to Bolivia’s slow revolutionary transformation.  But patterns of imposition and resistance continue and this paper argues that it is time for the United States to examine its assumptions so that the two nations can escape the cyclical patterns of the past. El trabajo que James Malloy publicó en 1970 (hasta hoy día uno de los esfuerzos analíticos más sistemáticos que se han hecho en inglés para entender la Revolución Nacional de 1952, argumentaba que la revolución permanecía "incompleta".

    Hoermann, Raphael

    2015-01-01

    This article explores the Gothicisation of the Haitian Revolution in the transatlantic discourse during the late eighteenth and early nineteenth centuries. As it argues, the Gothic mode has to be understood as a reaction to the profound challenges that the Haitian Revolution posed to a transatlantic world built on the slave economy. Pro-slavery and pro-colonialist authors demonised this successful slave revolution and one of the first anti-colonial revolutions in modern history by resorting f...

  12. E-health beyond technology: analyzing the paradigm shift that lies beneath.

    2018-03-01

    Information and computer technology has come to play an increasingly important role in medicine, to the extent that e-health has been described as a disruptive innovation or revolution in healthcare. The attention is very much focused on the technology itself, and advances that have been made in genetics and biology. This leads to the question: What is changing in medicine today concerning e-health? To what degree could these changes be characterized as a 'revolution'? We will apply the work of Thomas Kuhn, Larry Laudan, Michel Foucault and other philosophers-which offers an alternative understanding of progress and revolution in medicine to the classic discovery-oriented approach-to our analysis. Nowadays, the long-standing curative or reactive paradigm in medicine is facing a crisis due to an aging population, a significant increase in chronic diseases and the development of more expensive diagnostic tools and therapies. This promotes the evolution towards a new paradigm with an emphasis on preventive medicine. E-health constitutes an essential part of this new paradigm that seeks to solve the challenges presented by an aging population, skyrocketing costs and so forth. Our approach changes the focus from the technology itself toward the underlying paradigm shift in medicine. We will discuss the relevance of this approach by applying it to the surge in digital self-tracking through health apps and wearables: the recognition of the underlying paradigm shift leads to a more comprehensive understanding of self-tracking than a solely discovery-oriented or technology-focused view can provide.

  20. Exploiting the information revolution: call for independent evaluation of the latest English national experiment.

    Science.gov (United States)

    The English National Health Service (NHS) has a long history of national experiments with information technology; some successful, others less so. The NHS England Five Year Forward View aspires to 'Exploit the information revolution' through the transformational work of the National Information Board (NIB). NIB has published a 'Framework for Action' that promotes citizen empowerment, information availability, transparency, public trust, innovation, informatics skills and societal value. The framework sets out many laudable and common sense ambitions, but is light on evidence to support its aspirations, or plans for its evaluation. Considerable resource was invested in evaluation studies in the later stages of the National Programme for IT in England, but the analyses do not seem to have been included. Most of the cited evidence is from an unpublished report by management consultants rather than independent peer-reviewed work. National experiments of this importance should be evidence based and properly evaluated so that each iteration of 'information revolution' produces an evidence base to inform subsequent generations of care provision models and technology innovation. Evaluation should be planned from the very start rather than added in as an afterthought. Like any good business plan there should be defined critical success factors for health and social care, and a declaration of how they might be measured. Unintended consequences should be qualitatively explored. Evaluation should also consider critical-interpretive social perspectives to understand the human factors in technology deployment and should seek a theoretically informed insight into the mechanisms of change. The NHS Five Year Forward View and the NIB framework set out challenging ambitions based on transformative use of information technology and collaborative partnerships with commissioners and providers. The framework stands up very well against the Hayes principles, but the learning opportunities
