    Jones, L.M.; Migneron, R.; Narayanan, K.S.S.

    1987-01-01

    We show how integrodifferential equations typical of jet calculus can be combined with an averaging procedure to obtain jet-calculus-based results including the Mueller interference graphs. Results in longitudinal-momentum fraction x for physical quantities are higher at intermediate x and lower at large x than with the conventional ''incoherent'' jet calculus. These results resemble those of Marchesini and Webber, who used a Monte Carlo approach based on the same dynamics

  3. Technology transfer: The CANDU approach

    International Nuclear Information System (INIS)

    Hart, R.S.

    1998-01-01

    The many and diverse technologies necessary for the design, construction licensing and operation of a nuclear power plant can be efficiently assimilated by a recipient country through an effective technology transfer program supported by the firm long term commitment of both the recipient country organizations and the supplier. AECL's experience with nuclear related technology transfer spans four decades and includes the construction and operation of CANDU plants in five countries and four continents. A sixth country will be added to this list with the start of construction of two CANDU 6 plants in China in early 1997. This background provides the basis for addressing the key factors in the successful transfer of nuclear technology, providing insights into the lessons learned and introducing a framework for success. This paper provides an overview of AECL experience relative to the important factors influencing technology transfer, and reviews specific country experiences. (author)

  9. Macrosystems management approach to nuclear technology transfer

    International Nuclear Information System (INIS)

    Angelo, J.A. Jr.; Maultsby, T.E.

    1978-01-01

    The world of the 1980s will be a world of diminishing resources, shifting economic bases, rapidly changing cultural and societal structures, and an ever increasing demand for energy. A major driving function in this massive redistribution of global power is man's ability to transfer technology, including nuclear technology, to the developing nations. The major task facing policy makers in planning and managing technology transfer is to avoid the difficulties inherent in such technology exploitation, while maximizing the technical, economic, social, and cultural benefits brought about by the technology itself. But today's policy makers, using industrial-style planning, cannot adequately deal with all the complex, closely-coupled issues involved in technology transfer. Yet, policy makers within the developing nations must be capable of tackling the full spectrum of issues associated with technology transfer before committing to a particular course of action. The transfer and acceptance of complex technology would be significantly enhanced if policy makers followed a macrosystems management approach. Macrosystems management is a decision making methodology based on the techniques of macrosystems analysis. Macrosystems analysis combines the best quantitative methods in systems analysis with the best qualitative evaluations provided by multidisciplined task teams. These are focused in a project management structure to produce solution-oriented advice to the policy makers. The general relationships and management approach offered by macrosystems analysis are examined. Nowhere are the nuclear power option problems and issues more complex than in the transfer of this technology to developing nations. Although many critical variables of interest in the analysis are generic to a particular importer/exporter relationship, two specific issues that have universally impacted the nuclear power option, namely the fuel cycle, and manpower and training, are examined in the light of

    There is growing awareness of the impact of human activity on the climate and the need to stem this impact. Public health care decision makers from Sweden and the United Kingdom have started examining environmental impacts when assessing new technologies. This article considers the case for incorporating environmental impacts into the health technology assessment (HTA) process and discusses the associated challenges. Two arguments favor incorporating environmental impacts into HTA: 1) environmental changes could directly affect people's health and 2) policy decision makers have broad mandates and objectives extending beyond health care. Two types of challenges hinder this process. First, the nascent evidence base is insufficient to support the accurate comparison of technologies' environmental impacts. Second, cost-utility analysis, which is favored by many HTA agencies, could capture some of the value of environmental impacts, especially those generating health impacts, but might not be suitable for addressing broader concerns. Both cost-benefit and multicriteria decision analyses are potential methods for evaluating health and environmental outcomes, but are less familiar to health care decision makers. Health care is an important and sizable sector of the economy that could warrant closer policy attention to its impact on the environment. Considerable work is needed to track decision makers' demands, augment the environmental evidence base, and develop robust methods for capturing and incorporating environmental data as part of HTA.

    Sockolow, Paulina; Bowles, Kathryn H

    2008-01-01

    Project management is a critical skill for nurse informaticists who are in prominent roles developing and implementing clinical information systems. It should be included in the nursing informatics curriculum, as evidenced by its inclusion in informatics competencies and surveys of important skills for informaticists. The University of Pennsylvania School of Nursing includes project management in two of the four courses in the master's level informatics minor. Course content includes the phases of the project management process; the iterative unified process methodology; and related systems analysis and project management skills. During the introductory course, students learn about the project plan, requirements development, project feasibility, and executive summary documents. In the capstone course, students apply the system development life cycle and project management skills during precepted informatics projects. During this in situ experience, students learn, the preceptors benefit, and the institution better prepares its students for the real world.

  12. Pubertal induction in hypogonadism: Current approaches including use of gonadotrophins.

    Zacharin, Margaret

    2015-06-01

    Primary disorders of the gonad or those secondary to abnormalities of the hypothalamic pituitary axis result in hypogonadism. The range of health problems of childhood and adolescence that affect this axis has increased, as most children now survive chronic illness, but many have persisting deficits in gonadal function as a result of their underlying condition or its treatment. An integrated approach to hormone replacement is needed to optimize adult hormonal and bone health, and to offer opportunities for fertility induction and preservation that were not considered possible in the past. Timing of presentation ranges from birth, with disorders of sexual development, through adolescent pubertal failure, to adult fertility problems. This review addresses diagnosis and management of hypogonadism and focuses on new management strategies to address current concerns with fertility preservation. These include Turner syndrome, and fertility presevation prior to childhood cancer treatment. New strategies for male hormone replacement therapy that may impinge upon future fertility are emphasized. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Recent Cochrane reviews on falls and fall prevention have shown that it is possible to prevent falls in older adults living in the community and in care facilities. Technologies aimed at fall detection, assessment, prediction and prevention are emerging, yet there has been no consistency in describing or reporting on interventions using technologies. With the growth of eHealth and data driven interventions, a common language and classification is required. The FARSEEING Taxonomy of Technologies was developed as a tool for those in the field of biomedical informatics to classify and characterise components of studies and interventions. The Taxonomy Development Group (TDG) comprised experts from across Europe. Through face-to-face meetings and contributions via email, five domains were developed, modified and agreed: Approach; Base; Components of outcome measures; Descriptors of technologies; and Evaluation. Each domain included sub-domains and categories with accompanying definitions. The classification system was tested against published papers and further amendments undertaken, including development of an online tool. Six papers were classified by the TDG with levels of consensus recorded. Testing the taxonomy with papers highlighted difficulties in definitions across international healthcare systems, together with differences of TDG members' backgrounds. Definitions were clarified and amended accordingly, but some difficulties remained. The taxonomy and manual were large documents leading to a lengthy classification process. The development of the online application enabled a much simpler classification process, as categories and definitions appeared only when relevant. Overall consensus for the classified papers was 70.66%. Consensus scores increased as modifications were made to the taxonomy. The FARSEEING Taxonomy of Technologies presents a common language, which should now be adopted in the field of biomedical informatics. In developing the taxonomy as an

  16. Relativistic bound state approach to fundamental forces including gravitation

    Directory of Open Access Journals (Sweden)

    Morsch H.P.

    2012-06-01

    Full Text Available To describe the structure of particle bound states of nature, a relativistic bound state formalism is presented, which requires a Lagrangian including scalar coupling of two boson fields. The underlying mechanisms are quite complex and require an interplay of overlapping boson fields and fermion-antifermion production. This gives rise to two potentials, a boson-exchange potential and one identified with the long sought confinement potential in hadrons. With minimal requirements, two elementary massless fermions (quantons - with and without charge - and one gauge boson, hadrons and leptons but also atoms and gravitational systems are described by bound states with electric and magnetic coupling between the charges and spins of quantons. No need is found for colour, Higgs-coupling and supersymmetry.

    The aim of this paper is to present the marketing strategy and the application of management (marketing management) and advertising in order to increase the efficiency of innovative approach in clinical trials that include and involve the use of new technologies and transfer of technologies. This paper has a descriptive character and represents a narrative review of the literature and new model implementation. Marketing models are primarily used to improve the inclusion of a larger (and appropriate) number of patients, but they can be credited for the stay and monitoring of patients in the trial. Regulatory mechanisms play an important role in the application of various marketing strategies within clinical trials. The value for the patient as the most important stakeholder is defined in the field of clinical trials according to Kotler's value model for the consumer. In order to achieve the best results it is important to adequately examine all the elements of clinical trials and apply this knowledge in creation of a marketing plan that will be made in accordance with the legal regulations defined globally and locally. In this paper, two challenges have been highlighted for the adequate application of marketing tools in the field of clinical trials, namely: defining business elements in order to provide an adequate marketing approach for clinical trials and technology transfer and ensuring uniformity and regulatory affirmation of marketing attitudes in clinical trials in all regions in which they are carried out in accordance with ICH-GCP and valid regulations.

    Stone and Webster Engineering Corporation has developed a systematic program for achieving efficient, effective technology transfer. This program is based on transferring both know-why and know-how. The transfer of know-why and know-how is achieved most effectively by working in partnership with the recipient of the technology; by employing five primary transfer mechanisms, according to the type of learning required; by treating the technology transfer as a designed process rather than an isolated event; and by using a project management approach to control and direct the process. This paper describes the philosophy, process, and training mechanisms that have worked for Stone and Webster, as well as the project management approach needed for the most effective transfer of technology.

    Science.gov (United States)

    Liu, Bo

    Magnetic hard disk drive (HDD) technology is believed to be one of the most successful examples of modern mechatronics systems. The mechanical beauty of magnetic HDD includes simple but super high accuracy positioning head, positioning technology, high speed and stability spindle motor technology, and head-disk interface technology which keeps the millimeter sized slider flying over a disk surface at nanometer level slider-disk spacing. This paper addresses the challenges and possible approaches on how to further reduce the slider disk spacing whilst retaining the stability and robustness level of head-disk systems for future advanced magnetic disk drives.

  4. Approaching hospital administration about adopting cooling technologies.

    Science.gov (United States)

    Kirkland, Lisa L; Parham, William M; Pastores, Stephen M

    2009-07-01

    The purpose of this article is to provide intensivists with information and examples regarding cooling technology selection, cost assessment, adaptation, barriers, and presentation to hospital administrators. A review of medical and business literature was conducted using the following search terms: technology assessment, organizational innovation, intensive care, critical care, hospital administration, and presentation to administrators. General recommendations for intensivists are made for assessing cooling technology with descriptions of common new technology implementation stages. A study of 16 hospitals implementing a new cardiac surgery technology is described. A description of successful implementation of an induced hypothermia protocol by one of the authors is presented. Although knowledgeable about the applications of new technologies, including cooling technology, intensivists have little guidance or training on tactics to obtain a hospital administration's funding and support. Intensive care unit budgets are usually controlled by nonintensivists whose interests are neutral, at best, to the needs of intensivists. To rise to the top of the large pile of requisition requests, an intensivist's proposal must be well conceived and aligned with hospital administration's strategic goals. Intensivists must understand the hospital acquisition process and administrative structure and participate on high-level hospital committees. Using design thinking and strong leadership skills, the intensivist can marshal support from staff and administrators to successfully implement cooling technology.

  9. MODELS OF TECHNOLOGY ADOPTION: AN INTEGRATIVE APPROACH

    Directory of Open Access Journals (Sweden)

    Andrei OGREZEANU

    2015-06-01

    Full Text Available The interdisciplinary study of information technology adoption has developed rapidly over the last 30 years. Various theoretical models have been developed and applied such as: the Technology Acceptance Model (TAM, Innovation Diffusion Theory (IDT, Theory of Planned Behavior (TPB, etc. The result of these many years of research is thousands of contributions to the field, which, however, remain highly fragmented. This paper develops a theoretical model of technology adoption by integrating major theories in the field: primarily IDT, TAM, and TPB. To do so while avoiding mess, an approach that goes back to basics in independent variable type’s development is proposed; emphasizing: 1 the logic of classification, and 2 psychological mechanisms behind variable types. Once developed these types are then populated with variables originating in empirical research. Conclusions are developed on which types are underpopulated and present potential for future research. I end with a set of methodological recommendations for future application of the model.

  13. Technological Criteria Technology-Environmental under a Systemic Approach: Chemistry Technology Transfer

    Directory of Open Access Journals (Sweden)

    Durán-García Martín Enrique

    2014-07-01

    Full Text Available Currently the transfer of chemical technology is a process that contributes to the technology policy of a country, an industry or an organization in general chemistry. This process requires the application of clear criteria for the proper development of the complex interrelations in the transfer of chemical technology. A group of criteria that are present, are those related to environmental technology which intrinsically define the technology and its impact to the environment. Therefore, the transfer of chemical technology requires technological-environmental criteria defining, in conjunction with other criteria, an adequate process for the selection, acquisition and incorporation of technology in a holistic perspective, so it provides feasible solutions the chemical industry in pursuit of their goals. Then the criterion becomes a benchmark for assessing an appropriate technology transfer process. We performed a theoretical analysis of the technological and environmental criteria, proposing thirty-six (36 technological-environmental criteria interrelated under a systemic approach in the process of transfer of chemical technology, focused on a methodological cycle first run, based primarily on the research-action method. Future research is expected to make a refinement of the criteria from the formulation and validation of metrics so that necessary adjustments are made to optimize the process of transfer of chemical technology.

    In an article in this issue of Journal of Diabetes Science and Technology, Sherwyn Schwartz, M.D., presents a study to validate the design of the ClikSTAR® insulin pen from sanofi-aventis and demonstrates that the device can be used correctly by participants with diabetes. Concern with this article lies with the selection of participants, which was meant to reflect the intended audience for the insulin pen device but does not address the inclusion of visually impaired individuals, who comprise over 20% of the adult diabetes population. Visually impaired individuals need to be included as part of the intended audience for insulin administration technology, and manufacturers of these devices need to design their products for safe use by all people, including those who are visually impaired. The study demonstrated successful use of the ClikSTAR insulin pen in a population that did not include subjects with severe visual impairment. We believe that future validation studies for insulin administration technology should also include samples of visually impaired users and that visually impaired patients will embrace the use of insulin pens designed with their needs in mind. © 2010 Diabetes Technology Society.

    Constructing three dimensional (3-D) landscapes is an inevitable issue in deep study of biological ecologies, because in whatever scales in nature, all of the ecosystems are composed by complex 3-D environments and biological behaviors. Just imagine if a 3-D technology could help complex ecosystems be built easily and mimic in vivo microenvironment realistically with flexible environmental controls, it will be a fantastic and powerful thrust to assist researchers for explorations. For years, we have been utilizing and developing different technologies for constructing 3-D micro landscapes for biophysics studies in in vitro. Here, I will review our past efforts, including probing cancer cell invasiveness with 3-D silicon based Tepuis, constructing 3-D microenvironment for cell invasion and metastasis through polydimethylsiloxane (PDMS) soft lithography, as well as explorations of optimized stenting positions for coronary bifurcation disease with 3-D wax printing and the latest home designed 3-D bio-printer. Although 3-D technologies is currently considered not mature enough for arbitrary 3-D micro-ecological models with easy design and fabrication, I hope through my talk, the audiences will be able to sense its significance and predictable breakthroughs in the near future.

    Technological advances have allowed for the evolution of traditional dietary assessment methods. The aim of this review is to evaluate the accuracy of technology-based dietary assessment methods to determine carotenoid and/or fruit and vegetable intake when compared with carotenoid biomarkers. An online search strategy was undertaken to identify studies published in the English language up to July 2016. Inclusion criteria were adults ≥18 years, a measure of dietary intake that used information and communication technologies that specified fruit and/or vegetable intake or dietary carotenoid, a biomarker of carotenoid status and the association between the two. Sixteen articles from 13 studies were included with the majority cross-sectional in design (n = 9). Some studies used multiple dietary assessment methods with the most common: food records (n = 7), 24-h diet recalls (n = 5), food frequency questionnaires (n = 3) and diet quality assessed by dietary screener (n = 1). Two studies were directly web based, with four studies using technology that could be completed offline and data later transferred. Two studies utilised technology in the collection of dietary data, while the majority (n = 11) automated the collection in combination with nutrient analysis of the dietary data. Four studies provided correlation values between dietary carotenoids with biomarkers, ranging from r = 0.13 to 0.62 with the remaining studies comparing a measure of fruit and vegetable intake with biomarkers (r = 0.09 to 0.25). This review provides an overview of technology-based dietary assessment methods that have been used in validation studies with objectively measured carotenoids. Findings were positive with these dietary assessment measures showing mostly moderate associations with carotenoid biomarkers. PMID:28216582

  6. Cooperative technology development: An approach to advancing energy technology

    International Nuclear Information System (INIS)

    Stern, T.

    1989-09-01

    Technology development requires an enormous financial investment over a long period of time. Scarce national and corporate resources, the result of highly competitive markets, decreased profit margins, wide currency fluctuations, and growing debt, often preclude continuous development of energy technology by single entities, i.e., corporations, institutions, or nations. Although the energy needs of the developed world are generally being met by existing institutions, it is becoming increasingly clear that existing capital formation and technology transfer structures have failed to aid developing nations in meeting their growing electricity needs. This paper will describe a method for meeting the electricity needs of the developing world through technology transfer and international cooperative technology development. The role of nuclear power and the advanced passive plant design will be discussed. (author)

The realization of the possibility of such activity researches consider in implementation of technological approach in educational process. The scientists connect the optimal and qualitative realization of this activity with the implementation of education technology into learning process. Modern studies are focused on questions of implementation of technological approach into teaching foreign languages. It is thought to allow to achieve guaranteed minimal level of learning results. At the same time there are some incompletely studied aspects such as content of pedagogical technologies, their conceptual and procedural characteristics, approaches to classification. In the article the essence of technological approach is revealed, the communicatively focused technologies of teaching foreign languages in non-linguistic universities are concretized. The interpretation of technological approach is given; characteristics and attributes in teaching foreign languages are selected. It is noticed that technological approach is social and engineering ideology in the sphere of didactics according to which teaching process is considered to be a completely designed process with strictly planned and fixed results (M. Klarin. In the article it is emphasized on feasibility and efficiency of technological approach while teaching foreign languages, the degree of its integration in educational process is defined. The communication-oriented technologies, based on a communicative method of E. Passov, are allocated as the most optimum. It is shown the communication-oriented technologies go beyond the conceptual idea of modelling in teaching process of real foreign-language communication, and their procedural component and contents are founded on certain principles. The most commonly used technologies of teaching foreign languages are classified as technologies of modernization and technologies of

    2013-09-01

    Full Text Available Identifying the emerging requirements for technology management will help organisations to prepare for the future and remain competitive. Indeed technology management as a discipline needs to develop and respond to societal and industrial needs as well as the corresponding technology challenges. Therefore, following a review of technology forecasting methodologies, a sector-based scenario planning approach has been used to derive the emerging requirements for technology management. This structured framework provided an analytical lens to focus on the requirements for managing technology in the healthcare, energy and higher education sectors over the next 5-10 years. These requirements include the need for new business models to support the adoption of technologies; integration of new technologies with existing delivery channels; management of technology options including R&D project management; technology standards, validation and interoperability; and decision-making tools to support technology investment.

    Chakravarthi, Indira

    2013-01-01

    Medical devices and equipment have become an indispensable part of modern medical practice. Yet these medical technologies receive scant attention in the Indian context, both at the health policy level and as an area of study. There has been little attempt to systematically address the issue of equipment based medical technologies and how to regulate their use. There is paucity of primary data on the kind of medical equipment and techniques being introduced, on their need and relative usefulness, reliability, patterns of utilization, on their production, procurement, distribution, costs, and accessibility. This article reviews some of the policy issues relating to equipment based medical technology in India, in light of the specific choices and policies made during and after the colonial period in favour of modern medicine and a technology-based public health system, attempts at self-sufficiency and the current international environment with respect to the medical equipment and health-care industry.

    ice core drill is designed and tested. The expected average daily production of ice drilling would be not less than 25 m/day. The lower part of the drill is adapted for coring bed-rock using special tooth diamond bit. Deep ice coring requires a drilling fluid in the borehole during operation in order to keep the hole open and to compensate the hydrostatic pressures acting to close it. At present there are no ideal low-temperature drilling fluids as all of them are environmental and health hazardous substances. The new approaches of subglacial bedrock drilling technology are connected with utilization of environmental friendly, low-toxic materials, e.g. low-molecular dimethyl siloxane oils or aliphatic synthetic ester of ESTISOL™ 140 type. They have suitable density-viscosity properties, and can be consider as a viable alternative for drilling in glaciers and subglacial bedrock.

  2. A comprehensive approach to the design of ethanol supply chains including carbon trading effects.

    Science.gov (United States)

    Giarola, Sara; Shah, Nilay; Bezzo, Fabrizio

    2012-03-01

    The optimal design of biofuels production systems is a key component in the analysis of the environmental and economic performance of new sustainable transport systems. In this paper a general mixed integer linear programming modelling framework is developed to assess the design and planning of a multi-period and multi-echelon bioethanol upstream supply chain under market uncertainty. The optimisation design process of biofuels production systems aims at selecting the best biomass and technologies options among several alternatives according to economic and environmental (global warming potential) performance. A key feature in the proposed approach is the acknowledgement of an economic value to the overall GHG emissions, which is implemented through an emissions allowances trading scheme. The future Italian biomass-based ethanol production is adopted as a case study. Results show the effectiveness of the model as a decision making-tool to steer long-term decisions and investments.

    This report is one of a series designed to introduce British exporters to the opportunities offered by the Malaysian market. The Seventh Malaysia Plan, covering the five year period, 1996-2000, contains an ambitious menu of infrastructure projects. Total expenditure under the Plan is envisaged at RM450 billion, of which around RM380 billion will be sourced from the private sector. This is an indication of the wealth accumulated within the Malaysian economy. The infrastructure developments identified are designed to take the country towards Vision 2020. These infrastructure developments will continue to make the country highly attractive to foreign investors, who were the catalyst for Malaysia`s explosive growth over the last few years. Malaysian Corporations have also grown rapidly and are becoming international investors and traders in their own right, including in the United Kingdom. As they expand, seeking new markets, they are looking also for partners with whom they can share technology and jointly develop projects. Such companies are often ideal partners for UK companies wishing to enter the Malaysian and Asian market. Malaysia offers opportunities to companies prepared to make the small effort to know and understand the country and its people.

  8. Monitoring active volcanoes and mitigating volcanic hazards: the case for including simple approaches

    Science.gov (United States)

    Stoiber, Richard E.; Williams, Stanley N.

    1990-07-01

    Simple approaches to problems brought about eruptions and their ensuing hazardous effects should be advocated and used by volcanologists while awaiting more sophisticated remedies. The expedients we advocate have all or many of the following attributes: only locally available materials are required; no extensive training of operators or installation is necessary; they are affordable and do not require foreign aid or exports; they are often labor intensive and are sustainable without outside assistance. Where appropriate, the involvement of local residents is advocated. Examples of simple expedients which can be used in forecasting or mitigating the effects of crises emphasize the relative ease and the less elaborate requirements with which simple approaches can be activated. Emphasis is on visual observations often by untrained observers, simple meteorogical measurements, observations of water level in lakes, temperature and chemistry of springs and fumaroles, new springs and collapse areas and observations of volcanic plumes. Simple methods are suggested which can be applied to mitigating damage from mudflows, nuées ardentes, tephra falls and gas discharge. A review in hindsight at Ruiz includes the use of both chemical indicators and simple mudflow alarms. Simple expedients are sufficiently effective that any expert volcanologist called to aid in a crisis must include them in the package of advice offered. Simple approaches are a critical and logical complement to highly technical solutions to hazardous situations.

  10. A clinical pathway including psychotherapy approaches for managing emotional difficulties after acquired brain injury.

    Science.gov (United States)

    Coetzer, Rudi

    2009-11-01

    Emotional difficulties, such as anxiety and depression, are common after acquired brain injury in adults and can influence long-term outcome. Diagnosis in a brain injury context can be difficult. Ideally, rehabilitation approaches should consider the specific treatment of anxiety and depression as well and may include pharmacotherapy, individual psychotherapy, and family interventions. Psychotherapy, especially in regards to longer-term adjustment to brain injury, may have an important adjunctive role in treatment approaches, but adaptations of techniques may be needed. A clinical pathway is described which can help to raise clinicians awareness, as well as increase detection rates and consideration of the specific role of individual psychotherapy in this clinical population. However, an important caveat is that clinical pathways should not serve as a substitute, but rather a facilitator, for the process of reasoning about individual patients in everyday clinical practice.

  13. Using assistive technology adaptations to include students with learning disabilities in cooperative learning activities.

    Science.gov (United States)

    Bryant, D P; Bryant, B R

    1998-01-01

    Cooperative learning (CL) is a common instructional arrangement that is used by classroom teachers to foster academic achievement and social acceptance of students with and without learning disabilities. Cooperative learning is appealing to classroom teachers because it can provide an opportunity for more instruction and feedback by peers than can be provided by teachers to individual students who require extra assistance. Recent studies suggest that students with LD may need adaptations during cooperative learning activities. The use of assistive technology adaptations may be necessary to help some students with LD compensate for their specific learning difficulties so that they can engage more readily in cooperative learning activities. A process for integrating technology adaptations into cooperative learning activities is discussed in terms of three components: selecting adaptations, monitoring the use of the adaptations during cooperative learning activities, and evaluating the adaptations' effectiveness. The article concludes with comments regarding barriers to and support systems for technology integration, technology and effective instructional practices, and the need to consider technology adaptations for students who have learning disabilities.

Interdisciplinary research methods are salient to this effort. Technology evaluations are faced with a number of challenges including (1) the need to facilitate effective communication between social science researchers, technology specialists, and practitioners, (2) the need to better understand procedural and contextual aspects of a given technology, and (3) the need to generate findings that can be readily used for decision making and policy recommendations. Process and outcome evaluations of technology can be enhanced by integrating concepts from human factors engineering and information processing. This systemic approach, which focuses on the interaction between humans, technology, and information, enables researchers to better assess how a given technology is used in practice. Examples are drawn from complex technologies currently deployed within the criminal justice system where traditional evaluations have primarily focused on outcome metrics. Although this evidence-based approach has significant value, it is vulnerable to fully account for human and structural complexities that compose technology operations. Guiding principles for technology evaluations are described for identifying and defining key study metrics, facilitating communication within an interdisciplinary research team, and for understanding the interaction between users, technology, and information. The approach posited here can also enable researchers to better assess factors that may facilitate or degrade the operational impact of the technology and answer fundamental questions concerning whether the technology works as intended, at what level, and cost. © The Author(s) 2015.

    The US Department of Energy has provided support to Oak Ridge National Laboratory in order to pursue research leading to advanced, automated control of new innovative liquid-metal-cooled nuclear power plants. The purpose of this effort is to conduct research that will help to ensure improved operability, reliability, and safety for advanced LMRs. The plan adopted to achieve these program goals in an efficient and timely manner consists of utilizing, and advancing where required, state-of-the-art controls technology through close interaction with other national laboratories, universities, industry and utilities. A broad range of applications for the control systems strategies and the design environment developed in the course of this program is likely. A natural evolution of automated control in nuclear power plants is envisioned by ORNL to be a phased transition from today's situation of some analog control at the subsystem level with significant operator interaction to the future capability for completely automated digital control with operator supervision. The technical accomplishments provided by this program will assist the industry to accelerate this transition and provide greater economy and safety. The development of this transition to advanced, automated control system designs is expected to have extensive benefits in reduced operating costs, fewer outages, enhanced safety, improved licensability, and improved public acceptance for commercial nuclear power plants. 24 refs

    Point data derived from drilling logs must often be regionalized. However, aquifers may show discontinuous surface structures, such as the offset of an aquitard caused by tectonic faults. One main challenge has been to incorporate these structures into the regionalization process of point data. We combined ordinary kriging and inverse distance weighted (IDW) interpolation to account for neotectonic structures in the regionalization process. The study area chosen to test this approach is the largest porous aquifer in Austria. It consists of three basins formed by neotectonic events and delimited by steep faults with a vertical offset of the aquitard up to 70 m within very short distances. First, ordinary kriging was used to incorporate the characteristic spatial variability of the aquitard location by means of a variogram. The tectonic faults could be included into the regionalization process by using breaklines with buffer zones. All data points inside the buffer were deleted. Last, IDW was performed, resulting in an aquitard map representing the discontinuous surface structures. This approach enables one to account for such surfaces using the standard software package ArcGIS; therefore, it could be adopted in many practical applications.

    A false accusation of child abuse has a major impact on child and family. Conversely, a missed diagnosis of child abuse may have significant and lifelong consequences for the child. For health professionals the assessment of the nature of the injury and differentiating between accidental and inflicted injury, disease manifestation or a physiological phenomenon can be challenging. For adequate determination of the cause of injury, an integrated approach including paediatric knowledge and forensic medical expertise is essential. Therefore, a national expertise centre for child abuse (LECK) was established in the Netherlands in 2014. The first results of this integrated approach are described and illustrated with three case reports. Case A, a 7-month-old boy with an accidental humerus fracture. Case B, an 8-year-old boy with a false positive suspicion of child abuse who was eventually diagnosed with Henoch-Schönlein syndrome. Case C, boy of 3 months with bruises and a metaphyseal fracture of the femur, both highly suspected of being inflicted injury.

    Technology-induced errors are a growing concern for health care organizations. Such errors arise from the interaction between healthcare and information technology deployed in complex settings and contexts. As the number of health information technologies that are used to provide patient care rises so will the need to develop ways to improve the quality and safety of the technology that we use. The objective of the panel is to describe varying approaches to improving software safety from and organizational and health systems perspective. We define what a technology-induced error is. Then, we discuss how software design and testing can be used to improve health information technologies. This discussion is followed by work in the area of monitoring and reporting at a health district and national level. Lastly, we draw on the quality, safety and resilience literature. The target audience for this work are nursing and health informatics researchers, practitioners, administrators, policy makers and students.

    Despite on the improvements in the quality of high-rise construction areas and industrial wastewater treatment, the pollution of water bodies continues to increase. This is due to the organized and unorganized surface untreated sewage entry into the reservoirs. The qualitative analysis of some cities' surface sewage composition is carried out in the work. Based on the published literature review, the characteristic contamination present in surface wastewater was identified. The paper proposes a new technology for the treatment of surface sewage and presents the results of preliminary studies.

  4. Proven approaches to organise a large decommissioning project, including the management of local stakeholder interests

    Full text: Spanish experience holds a relatively important position in the field of the decommissioning of nuclear and radioactive facilities. Decommissioning projects of uranium concentrate mill facilities are near completion; some old uranium mine sites have already been restored; several projects for the dismantling of various small research nuclear reactors and a few pilot plants are at various phases of the dismantling process, with some already completed. The most notable Spanish project in this field is undoubtedly the decommissioning of the Vandellos 1 nuclear power plant that is currently ready to enter a safe enclosure, or dormancy, period. The management of radioactive wastes in Spain is undertaken by 'Empresa Nacional de Residuos Radioactivos, S.A.' (ENRESA), the Spanish national radioactive waste company, constituted in 1984. ENRESA operates as a management company, whose role is to develop radioactive waste management programmes in accordance with the policy and strategy approved by the Spanish Government. Its responsibilities include the decommissioning and dismantling of nuclear installations. Decommissioning and dismantling nuclear installations is an increasingly important topic for governments, regulators, industries and civil society. There are many aspects that have to be carefully considered, planned and organised in many cases well in advance of when they really need to be implemented. The goal of this paper is describe proven approaches relevant to organizing and managing large decommissioning projects, in particular in the case of Vandellos-1 NPP decommissioning. (author)

    The two approaches of consistent quantum field theory for systems of the trapped Bose-Einstein condensates are known, one is the Bogoliubov-de Gennes approach and the other is the generalized Bogoliubov approach. In this paper, we investigate the relation between the two approaches and show that they are formally equivalent to each other. To do this one must carefully treat the Nambu-Goldstone mode which plays a crucial role in the condensation. It is emphasized that the choice of vacuum is physically relevant

    2008-01-01

    This article presents the Catholic Christian tradition and teaching on the moral respect due to human life from conception, supported by natural law moral philosophical reasoning. This approach contrasts with the ethical views of secular philosophers on human embryo research for therapeutic purposes. The challenges for Catholic healthcare institutions is to find ethical ways of using suitable pluripotent stem cells for therapies without creating or destroying human embryos. Catholic teaching on infertility treatment and reproductive technology are presented with emphasis given to the ethical need for children to be conceived and born of the marriage union compared with alterative ethical approaches for the use of infertility treatment and reproductive technology.

    2018-01-07

    With the extensive applications of biomagnetic signals derived from active biological tissue in both clinical diagnoses and human-computer-interaction, there is an increasing need for approachable weak biomagnetic sensing technology. The inherent merits of giant magnetoresistance (GMR) and its high integration with multiple technologies makes it possible to detect weak biomagnetic signals with micron-sized, non-cooled and low-cost sensors, considering that the magnetic field intensity attenuates rapidly with distance. This paper focuses on the state-of-art in integrated GMR technology for approachable biomagnetic sensing from the perspective of discipline fusion between them. The progress in integrated GMR to overcome the challenges in weak biomagnetic signal detection towards high resolution portable applications is addressed. The various strategies for 1/ f noise reduction and sensitivity enhancement in integrated GMR technology for sub-pT biomagnetic signal recording are discussed. In this paper, we review the developments of integrated GMR technology for in vivo/vitro biomagnetic source imaging and demonstrate how integrated GMR can be utilized for biomagnetic field detection. Since the field sensitivity of integrated GMR technology is being pushed to fT/Hz 0.5 with the focused efforts, it is believed that the potential of integrated GMR technology will make it preferred choice in weak biomagnetic signal detection in the future.

    2016-01-01

    This book explores emerging trends in wearable sensors for sport and highlights the developments taking place. Drawing on the literature both the approaches and principals for the use of sensors in sport are outlined, and together with references to key works the reader finds this useful in considering such endeavours. The development of wearable technologies is fast paced and accompanying that is an exponential growth in the use and development of computing resources, thus while the review is comprehensive on content not all works can be included and given publication times will inevitably be somewhat dated. The illumination through trends, examples and principles are an aid for anyone considering the use of sensors and wearables in sports.

    2010-01-01

    Complex technology investment decisions within NASA are increasingly difficult to make such that the end results are satisfying the technical objectives and all the organizational constraints. Due to a restricted science budget environment and numerous required technology developments, the investment decisions need to take into account not only the functional impact on the program goals, but also development uncertainties and cost variations along with maintaining a healthy workforce. This paper describes an approach for optimizing and qualifying technology investment portfolios from the perspective of an integrated system model. The methodology encompasses multi-attribute decision theory elements and sensitivity analysis. The evaluation of the degree of robustness of the recommended portfolio provides the decision-maker with an array of viable selection alternatives, which take into account input uncertainties and possibly satisfy nontechnical constraints. The methodology is presented in the context of assessing capability development portfolios for NASA technology programs.

  18. New Nuclear Materials Including Non Metallic Fuel Elements. Vol. II. Proceedings of the Conference on New Nuclear Materials Technology, Including Non Metallic Fuel Elements

    International Nuclear Information System (INIS)

    1963-01-01

    One of the major aims of the International Atomic Energy Agency in furthering the peaceful uses of atomic energy is to encourage the development of economical nuclear power. Certainly, one of the more obvious methods of producing economical nuclear power is the development of economical fuels that can be used at high temperatures for long periods of time, and which have sufficient strength and integrity to operate under these conditions without permitting the release of fission products. In addition it is desirable that after irradiation these new fuels be economically reprocessed to reduce further the cost of the fuel cycle. As nuclear power becomes more and more competitive with conventional power the interest in new and more efficient higher-temperature fuels naturally increases rapidly. For these reasons, the Agency organized a Conference on New Nuclear Materials Technology, Including Non-Metallic Fuel Elements, which was held from 1 to 5 July 1963 at the International Hotel, Prague, with the assistance and co-operation of the Government of the Czechoslovak Socialist Republic. A total of 151 scientists attended, from 23 countries and 4 international organizations. The participants heard and discussed more than 60 scientific papers. The Agency wishes to thank the scientists who attended this Conference for their papers and for many spirited discussions that truly mark a successful meeting. The Agency wishes also to record its gratitude for the assistance and generous hospitality accorded the Conference, the participants and the Agency's staff by the Government of the Czechoslovak Socialist Republic and by the people of Prague. The scientific information contained in these Proceedings should help to quicken the pace of progress in the fabrication of new and m ore economical fuels, and it is hoped that these proceedings will be found useful to all workers in this and related fields

  19. A Mixed Learning Technology Approach for Continuing Medical Education

    2003-01-01

    Full Text Available Introduction: Distance learning technologies have been used for many years to provide CME to rural physicians. The purpose of this study was to evaluate the utility and acceptability of a mixed learning technology approach for providing distance CME. The approach combined audio teleconferencing instruction with a Web-based learning system enabling the live presentation and archiving of instructional material and media, asynchronous computer conferencing discussions, and access to supplemental online learning resources. Methodology: The study population was comprised of physicians and nurse practitioners who participated in audio teleconference sessions, but did not access the Web-based learning system (non-users; learners who participated in audio teleconferences and accessed the Web-based system (online users; and faculty. The evaluation focused upon faculty and learners’ experiences and perceptions of the mixed learning technology approach; the level of usage; and the effectiveness of the approach in fostering non-mandatory, computer-mediated discussions. Results and Discussion: The users of the Web-based learning system were satisfied with its features, ease of use, and the ability to access online CME instructional material. Learners who accessed the system reported a higher level of computer skill and comfort than those who did not, and the majority of these users accessed the system at times other than the live audio teleconference sessions. The greatest use of the system appeared to be for self-directed learning. The success of a mixed learning technology approach is dependent on Internet connectivity and computer access; learners and faculty having time to access and use the Web; comfort with computers; and faculty development in the area of Web-based teaching.

  20. Sustainable Use of Technology in Teaching: A Principled Approach

    Full Text Available The bewildering pace of change in technology has had a polarizing effect on the teaching profession.  Teachers tend to cope in two ways, either by finding the least invasive ways to use technology without interfering with their standard mode of practice, or by embracing technology at every step and turn in new and innovative ways.  The former does a disservice to students, but the latter is unsustainable.  This research explores the sustainability of using technology in teaching and puts forward principles and guidelines to determine the most effective technology to use in the most sustainable fashion.  In this framework, the onus is put on students to complete active learning projects in and outside the classroom.  The resulting learning environment and the learning activities employed in the classroom are investigated in this study. Data were collected via field notes, student interviews, researcher journal entries, and student reflections.  The findings of this research indicate that a principled approach to the sustainable use of technology in teaching fosters a student-centered orientation which raises student motivation, reduces the affective filter and builds confidence without placing undue pressure on the teacher or on limited educational resources.

  1. A DYNAMICAL SYSTEM APPROACH IN MODELING TECHNOLOGY TRANSFER

    Directory of Open Access Journals (Sweden)

    Hennie Husniah

    2016-05-01

    Full Text Available In this paper we discuss a mathematical model of two parties technology transfer from a leader to a follower. The model is reconstructed via dynamical system approach from a known standard Raz and Assa model and we found some important conclusion which have not been discussed in the original model. The model assumes that in the absence of technology transfer from a leader to a follower, both the leader and the follower have a capability to grow independently with a known upper limit of the development. We obtain a rich mathematical structure of the steady state solution of the model. We discuss a special situation in which the upper limit of the technological development of the follower is higher than that of the leader, but the leader has started earlier than the follower in implementing the technology. In this case we show a paradox stating that the follower is unable to reach its original upper limit of the technological development could appear whenever the transfer rate is sufficiently high.  We propose a new model to increase realism so that any technological transfer rate could only has a positive effect in accelerating the rate of growth of the follower in reaching its original upper limit of the development.

  2. A practical approach to the transfer of nuclear technology

    International Nuclear Information System (INIS)

    Segerberg, F.

    1978-01-01

    The paper deals specifically with the transfer of light-water reactor technology to a developing country. The technology transfer scheme presented assumes that Sweden is the supplier of this technology. The basis of the proposed approach is that hardware deliveries for nuclear power plants in the recipient country should constitute an activity in parallel with the general technology transfer. It is pointed out that the developing countries form a very heterogeneous group with respect to industrial capability. On the other hand the supplier nations are not a homogeneous group. Sweden's most relevant characteristics as supplier nation can be summarized under the following headings: (i) fairly small and highly industrialized country; (ii) concentration on nuclear power to cover increasing electricity demands; (iii) independent reactor technology; (iv) well-established infrastructure with regard to component manufacturing; (v) political neutrality. It follows that each combination of two countries constitutes a unique example. The nuclear technology transfer schemes must consequently be extremely flexible. The paper outlines a 'modular' system. This concept means that the supplier offers a great variety of independent courses, training opportunities, facilities etc. which can then be combined into a package meeting the wishes of the recipient nation. The components in a Swedish package of this kind are elaborated. The paper ends with the general conclusion that Sweden has so far been successful in combining high national ambitions with limited manpower and limited financial resources. The underlying efficiency and flexibility will hopefully make Sweden an attractive partner for developing countries. (author)

    In summary, major paradigm shifts in the health care industry are altering the way technology is maintained and supported. Service organizations are now responsible for maintaining a broader base of technology within the health care delivery network and must to this on an extremely rapid, efficient, and productive basis. A number of new technologies are coming on-line, which can allow a health care technology service organization to experience significant improvements in profitability, efficiency, and productivity. To realize maximum benefit from these technologies, service organizations may find themselves re-engineering their service processes. The author believes that this is a requirement for many service organizations, regardless of whether new technology is implemented. The traditional approaches to service delivery are ineffective in managing the new structural realities and service requirements of today's health care environment. New strategies and tactics are required for ensuring that these requirements are met. These approaches will no doubt improve the overall quality, productivity, and efficiency of service and are based on best practices utilized by leading OEMs and ISOs in the medical electronics and other high technology service industry such as information technology and telecommunications, where the service organization is responsible for supporting a broad array of the technology over a large geography with a densely populated installed base, not unlike the typical health care delivery service environment. Once operational improvements are made, a service organization can take advantage of the productivity and efficiency gains brought on by new technology. Organizations interested in doing so are urged to thoroughly research the current state-of-the-art and best practices, because there are numerous systems currently available off-the-shelf. The author believes that new technology will be a basic requirement for competing in the health care

  7. Implementing Educational Technology in Higher Education: A Strategic Approach

    Directory of Open Access Journals (Sweden)

    Cynthia C. Roberts

    2008-01-01

    Full Text Available Although the move toward implementing technology in higher education is driven by an increasing number of competitors as well as student demand, there is still considerable resistance to embracing it. Adoption of technology requires more that merely installing a product. This paper outlines a framework for a strategic change process that can be utilized by educators for the purpose of the selection as well as successful implementation of educational technologies within their setting, in particular, online course management systems. The four steps of this process include strategic analysis, strategy making, strategic plan design, and strategic plan implementation. The choice to embrace a new system and the extent and speed of its implementation depends upon internal factors such as resources, organizational culture, faculty readiness, anticipated degree of resistance, and the degree of variance from the status quo. A case from the author’s experience provides one example of how the use of distance learning technology was strategically implemented.

  8. A heuristic approach to optimization of structural topology including self-weight

    Science.gov (United States)

    Tajs-Zielińska, Katarzyna; Bochenek, Bogdan

    2018-01-01

    Topology optimization of structures under a design-dependent self-weight load is investigated in this paper. The problem deserves attention because of its significant importance in the engineering practice, especially nowadays as topology optimization is more often applied when designing large engineering structures, for example, bridges or carrying systems of tall buildings. It is worth noting that well-known approaches of topology optimization which have been successfully applied to structures under fixed loads cannot be directly adapted to the case of design-dependent loads, so that topology generation can be a challenge also for numerical algorithms. The paper presents the application of a simple but efficient non-gradient method to topology optimization of elastic structures under self-weight loading. The algorithm is based on the Cellular Automata concept, the application of which can produce effective solutions with low computational cost.

  9. Pfirsch-Tasso versus standard approaches in the plasma stability theory including the resistive wall effects

    Pustovitov, V. D.

    2017-11-01

    The study is devoted to theoretical description of plasma stability in toroidal fusion systems with a resistive wall. Its aim is elimination of contradictions between the models recently developed for the resistive wall mode analysis and the Pfirsch-Tasso approach originated from the paper published in 1971 [D. Pfirsch and H. Tasso, Nucl. Fusion 11, 259 (1971)]. The main relations have been given there without detailed proofs. Here, a missing chain of derivations is restored and earlier unknown limitations that restrict the applicability of the Pfirsch-Tasso energy principle are established. Its replacement valid in a wider area is proposed. The new result is free from the constraints implicitly imposed in the Pfirsch-Tasso procedure and can be used with any plasma model (not necessarily ideal) and for arbitrary perturbations. The proposed extensions allow applications for analysis of the rotational stabilization and optimization of the ITER scenarios.

    BioModels serves as a central repository of mathematical models representing biological processes. It offers a platform to make mathematical models easily shareable across the systems modelling community, thereby supporting model reuse. To facilitate hosting a broader range of model formats derived from diverse modelling approaches and tools, a new infrastructure for BioModels has been developed that is available at http://www.ebi.ac.uk/biomodels. This new system allows submitting and sharing of a wide range of models with improved support for formats other than SBML. It also offers a version-control backed environment in which authors and curators can work collaboratively to curate models. This article summarises the features available in the current system and discusses the potential benefit they offer to the users over the previous system. In summary, the new portal broadens the scope of models accepted in BioModels and supports collaborative model curation which is crucial for model reproducibility and sharing. © The Author(s) 2017.

  14. Including the monetary part in macro accounting: A ‘modern’ approach to the macroeconomic accounting

    Directory of Open Access Journals (Sweden)

    Onur TUTULMAZ

    2014-12-01

    Full Text Available Economic output is placed at the heart of the macroeconomics. To calculate the output one needs to achieve simplifying a high level complexity of economic relationships to form a system. On the flip side, the model should be enough elaborated to be able to reflect the important relationships. In this manner, the classical macroeconomic identity as Keynes suggested is simple enough to understand the main elements but it does not show the financial parts of transactions. Not having the monetary part of the economy it lacks the coherence. With the financial and economic crises getting more frequent, more endeavour to build a more inclusive and coherent macroeconomic system has been observed. However, there are large variety in different options of simplifying and simulating complex relationships among the real and monetary part of the modern economies.  Our paper tries to set an analysis comparing some of the recent prominent ideas in building balance sheet and transaction flow matrix in regard to macroeconomic accounting system. We can conclude the new achievement of including the monetary transactions in the frame causes a compromise from the simplicity for a coherent and more complete picture of macro economy.

    2014-06-01

    Full Text Available Irish educational policy acknowledges the importance of integrating technology meaningfully into teaching and learning at the primary level. Much remains to be done, however, in terms of developing, practically implementing and evaluating the use of technology in the Irish primary classroom. This paper describes a study on the use of a structured approach to digital storytelling as a tool for meaningful technology integration with children at primary level. In this study, the researcher developed a structured approach for implementing digital storytelling with primary school children, and collaborated with a class teacher in an Irish primary school to prepare to implement the approach. Multiple qualitative methods were used to evaluate the implementation, including interviews with the teacher, classroom observation, and focus group interviews with participating children. The results suggested that this structured approach to digital storytelling has the potential to be used successfully as a meaningful technology integration approach with this cohort. The findings also explored implications for the implementation of digital storytelling at primary level, and identified aspects on which further research should be undertaken to enhance and extend the approach that was used.

    Kambe, Hidetoshi; Mitsui, Hiroyasu; Endo, Satoshi; Koizumi, Hisao

    The applications of embedded system technologies have spread widely in various products, such as home appliances, cellular phones, automobiles, industrial machines and so on. Due to intensified competition, embedded software has expanded its role in realizing sophisticated functions, and new development methods like a hardware/software (HW/SW) co-design for uniting HW and SW development have been researched. The shortfall of embedded SW engineers was estimated to be approximately 99,000 in the year 2006, in Japan. Embedded SW engineers should understand HW technologies and system architecture design as well as SW technologies. However, a few universities offer this kind of education systematically. We propose a student experiment method for learning the basics of embedded system development, which includes a set of experiments for developing embedded SW, developing embedded HW and experiencing HW/SW co-design. The co-design experiment helps students learn about the basics of embedded system architecture design and the flow of designing actual HW and SW modules. We developed these experiments and evaluated them.

    Borsci, Simone; Uchegbu, Ijeoma; Buckle, Peter; Ni, Zhifang; Walne, Simon; Hanna, George B

    2018-01-01

    The slow adoption of innovation into healthcare calls into question the manner of evidence generation for medical technology. This paper identifies potential reasons for this including a lack of attention to human factors, poor evaluation of economic benefits, lack of understanding of the existing healthcare system and a failure to recognise the need to generate resilient products. Areas covered: Recognising a cross-disciplinary need to enhance evidence generation early in a technology's life cycle, the present paper proposes a new approach that integrates human factors and health economic evaluation as part of a wider systems approach to the design of technology. This approach (Human and Economic Resilience Design for Medical Technology or HERD MedTech) supports early stages of product development and is based on the recent experiences of the National Institute for Health Research London Diagnostic Evidence Co-operative in the UK. Expert commentary: HERD MedTech i) proposes a shift from design for usability to design for resilience, ii) aspires to reduce the need for service adaptation to technological constraints iii) ensures value of innovation at the time of product development, and iv) aims to stimulate discussion around the integration of pre- and post-market methods of assessment of medical technology.

    In a world increasingly more competitive and in a constantly development and growth it's important that companies have economic tools, like frameworks to help them to evaluate and validate the technology development to better fits in each company particular needs. The paper presents an evaluation approach for research project pilot applications to stimulate its implementation and deployment, increasing its adequacy and acceptance to their stakeholders and consequently providing new business profit and opportunities. Authors used the DECIDE evaluation framework as a major guide to this approach, which was tested in the iSURF project to support the implementation of an interoperability service utility for collaborative supply chain planning across multiple domains supported by RFID devices.

  1. The walkshop approach to science and technology ethics.

    2015-02-01

    In research and teaching on ethical aspects of emerging sciences and technologies, the structure of working environments, spaces and relationships play a significant role. Many of the routines and standard practices of academic life, however, do little to actively explore and experiment with these elements. They do even less to address the importance of contextual and embodied dimensions of thinking. To engage these dimensions, we have benefitted significantly from practices that take us out of seminar rooms, offices and laboratories as well as beyond traditional ways of working and interacting. We have called one such practice the 'walkshop'. Through walkshops, we have spent several days walking together with our colleagues and students in open outdoor spaces, keeping a sustained intellectual discussion on ethical aspects of science, technology and innovation while moving through these landscapes. For us, this has generated useful opportunities to escape established hierarchies, roles and patterns of thought and to rethink conceptual and philosophical issues from new perspectives, under new attitudes and with renewed energy. In this paper we wish to highlight the potential benefits of the walkshop approach by sharing some of our experiences and describing how we have prepared for and carried out these events. We share this information in the hope that we may encourage others to both experiment with the walkshop approach and exchange information on their own innovative processes for research and teaching in science and engineering ethics.

  2. Specificity of continuous auditing approach on information technology internal controls

    Directory of Open Access Journals (Sweden)

    Kaćanski Slobodan

    2012-01-01

    Full Text Available Contemporary business world, can not be imagined without the use of information technology in all aspects of business. The use of information technology in manufacturing and non-production companies' activities can greatly facilitate and accelerate the process of operation and control. Because of its complexity, they possess vulnerable areas and provide space for the emergence of accidental and intentional frauds that can significantly materially affect the business decisions made by the companies' management. Implementation of internal controls can greatly reduce the level of errors that can contribute to making the wrong decisions. In order to protect the operating system, the company's management implement an internal audit to periodically examine the fundamental quality of the internal control systems. Since the internal audit, according to its character, only periodically checks quality of internal control systems and information technologies to be reported to the manager, the problem arises in the process of in wrong time reporting the management structures of the business entity. To eliminate this problem, management implements a special approach to internal audit, called continuous auditing.

  3. Innovative technological paradigm-based approach towards biofuel feedstock

    2017-01-01

    Highlights: • DAS was developed through an innovative approach towards literature mining and technological paradigm theory. • A novel concept of biofuel feedstock development paradigm (BFDP) is proposed. • The biofuel production diffusion velocity model gives predictions for the future. • Soft path appears to be the driving force for the new paradigm shift. • An integrated biofuel production feedstock system is expected to play a significant role in a low-carbon sustainable future. - Abstract: Biofuels produced from renewable energy biomass are playing a more significant role because of the environmental problems resulting from the use of fossil fuels. However, a major problem with biofuel production is that despite the range of feedstock that can be used, raw material availability varies considerably. By combining a series of theories and methods, the research objective of this study is to determine the current developments and the future trends in biofuel feedstock. By combining technological paradigm theory with literature mining, it was found that biofuel feedstock production development followed a three-stage trajectory, which was in accordance with the traditional technological paradigm – the S-curve. This new curve can be divided into BFDP (biofuel feedstock development paradigm) competition, BFDP diffusion, and BFDP shift. The biofuel production diffusion velocity model showed that there has been constant growth from 2000, with the growth rate reaching a peak in 2008, after which time it began to drop. Biofuel production worldwide is expected to remain unchanged until 2030 when a paradigm shift is expected. This study also illustrates the results of our innovative procedure – a combination of the data analysis system and the technological paradigm theory – for the present biofuel feedstock soft path that will lead to this paradigm shift, with integrated biofuel production feedstock systems expected to be a significant new trend.

    2012-01-01

    Full Text Available Grouping parts into families which can be produced by a cluster of machine cells is the cornerstone of cellular manufacturing, which in turn is the building block for flexible manufacturing systems. Cellular manufacturing is a group technology (GT concept that has recently attracted the attention of manufacturing firms operating under jobshop environment to consider redesigning their manufacturing systems so as to take advantage of increased throughput, reduction in work-in-progress, set-up time, and lead times; leading to product quality and customer satisfaction. The paper presents a generalised approach for machine cell formation from a jobshop using similarity order clustering technique for preliminary cell grouping and considering machine utilisation for the design of nonintergrouping material handling using the single-pass heuristic. The work addresses the shortcomings of cellular manufacturing systems design and implementations which ignore machine utilisations, group sizes and intergroup moves.

    2017-04-01

    This poster session presents some ideas and approaches to understand concepts of thermal equilibrium, temperature and heat in order to bulid a man-nature relationship in a harmonious and responsible manner, emphasizing the interaction between science and technology, without neglecting the relationship of the environment and society, an approach to sustainability. It is proposed the development of practices that involve the use of modern technology, of easy access and low cost to measure temperature. We believe that the Arduino microcontroller and some temperature sensors can open the doors of innovation to carry out such practices. In this work we present some results of simple practices presented to a population of students between the ages of 16 and 17 years old. The practices in this proposal are: Zero law of thermodynamics and the concept of temperature, calibration of thermometers and measurement of temperature for heating and cooling of three different substances under the same physical conditions. Finally the student is asked to make an application that involves measuring of temperature and other physical parameters. Some suggestions are: to determine the temperature at which we take some food, measure the temperature difference at different rooms of a house, housing constructions that favour optimal condition, measure the temperature of different regions, measure of temperature trough different colour filters, solar activity and UV, propose applications to understand current problems such as global warming, etc. It is concluded that the Arduino practices and electrical sensors increase the cultural horizon of the students while awaking their interest to understand their operation, basic physics and its application from a modern perspective.

    Kim, Jeong Chul; Ronco, Claudio

    2011-01-01

    A wearable artificial kidney (WAK) is a device that continuously supports renal function during ambulation or social activities out of hospital. With the aim of improving dialysis patients' quality of life, WAK systems have been in development for several decades. Technological evolutions in dialysis membrane and dialysate regeneration have been paving the way to wearability, and the possibility of implantation, for renal replacement therapies. However, at present, there are many technical issues confronting the attempts to apply WAK systems in clinical practice. Here, we have reviewed the necessary technical requirements and the WAKs currently being developed that are trying to meet these. Aside from technical issues, ethical, legal and economic aspects should be also considered together, in order to minimize trial and error in the development of the WAK. Continuous follow- up, integration with emerging new technologies, and multidisciplinary approaches involving clinicians, engineers, economists and social scientists are required for the realization of WAK in clinical practice.

  11. Cosmic Evolutionary Philosophy and a Dialectical Approach to Technological Singularity

    Directory of Open Access Journals (Sweden)

    Cadell Last

    2018-04-01

    Full Text Available The anticipated next stage of human organization is often described by futurists as a global technological singularity. This next stage of complex organization is hypothesized to be actualized by scientific-technic knowledge networks. However, the general consequences of this process for the meaning of human existence are unknown. Here, it is argued that cosmic evolutionary philosophy is a useful worldview for grounding an understanding of the potential nature of this futures event. In the cosmic evolutionary philosophy, reality is conceptualized locally as a universal dynamic of emergent evolving relations. This universal dynamic is structured by a singular astrophysical origin and an organizational progress from sub-atomic particles to global civilization mediated by qualitative phase transitions. From this theoretical ground, we attempt to understand the next stage of universal dynamics in terms of the motion of general ideation attempting to actualize higher unity. In this way, we approach technological singularity dialectically as an event caused by ideational transformations and mediated by an emergent intersubjective objectivity. From these speculations, a historically-engaged perspective on the nature of human consciousness is articulated where the truth of reality as an emergent unity depends on the collective action of a multiplicity of human observers.

    In April of this past year, Transatlantic Innovations brought a variety of organizations and industry together for an international exchange of ideas, new technology, and current trends in plastic surgery. The meeting was highly interactive and included audience response devices. The focus was on 10 major areas: (1) new surgical techniques; (2) composite allografts versus conventional techniques, facing the future; (3) interspecialty collaboration versus competition; (4) the business of plastic surgery, best practices; (5) the image of the plastic surgeon, branding yourself; (6) medical tourism; (7) publicity; (8) the regulation of innovation, U.S. Food and Drug Administration and European Medicines Agency perspective; (9) the future of plastic surgery, cutting edge technologies; and (10) applications and controversies in fat grafting. The meeting concluded with the 8th International Committee for Quality Assurance, Medical Technologies and Devices in Plastic Surgery Consensus Conference with the development of a consensus statement. Through an interactive audience response system, additional questions and attitudes were asked of the audience and, in real time, international differences were identified, which led to further discussions from panelists. Responses were identified in three major groups: European Union, North America, and the Rest of the World. Responses and data are included in this article. The meeting brought participants, industry, regulators, and educators from both sides of the Atlantic. The interaction of these groups in these outlined topics brought a unique perspective to the meeting and, in the end, volumes of data. We have more in common than we believe. It is our anticipation that as we as plastic surgeons move forward, we can use these interactions to help our own practices but more specifically the specialty as a whole.

    Full Text Available With the progress of modern sciences and more competitive becoming environment in the technology era, knowledge management is being counted as one of the most important stable competitive advantages of technology oriented organizations. This matter is of higher importance in high technology organizations, especially those active in information technology field due to their unique identity. This way, knowledge management has been already shifted to one of the most important priorities of such organizations that in case of not identifying, applying, recording and creating that knowledge, the organization is inevitable to pay fortunesto revive the knowledge gone. The purpose of this research is presenting a comprehensive knowledge management implementation model in information technology industry. Therefore, the measures of the suggested research’s model were identified by studying identical researches and projects done in knowledge management and information technology sector and also through consultation with the experts. This way, a questionnaire was designed in two parts and distributed among experts in the understudied organizations. The research’s data were analyzed through T Test and Binomial Test through fuzzy approach due to the constraints presented by the Lickert scale. The research findings demonstrate that the stages of knowledge management implementation model in information technology sector include knowledge evaluation, knowledge leverage, knowledge planning, knowledge culture, knowledge strategies, knowledge management processes, suitable knowledge infrastructures, knowledge organization and knowledge presentation. There also exist actions in each stage that effect successful implementation of the mentioned stages.

    Soil salinity management can be complex, expensive, and time demanding, especially in arid and semi-arid regions. Besides taking no action, possible management strategies include amelioration and adaptation measures. Here we apply the World Overview of Conservation Approaches and Technologies (WOCAT) framework for the systematic analysis and evaluation and selection of soil salinisation amelioration technologies in close collaboration with stakeholders. The participatory approach is applied in the RECARE (Preventing and Remediating degradation of soils in Europe through Land Care) project case study of Timpaki, a semi-arid region in south-central Crete (Greece) where the main land use is horticulture in greenhouses irrigated by groundwater. Excessive groundwater abstractions have resulted in a drop of the groundwater level in the coastal part of the aquifer, thus leading to seawater intrusion and in turn to soil salinisation. The documented technologies are evaluated for their impacts on ecosystem services, cost, and input requirements using a participatory approach and field evaluations. Results show that technologies which promote maintaining existing crop types while enhancing productivity and decreasing soil salinity are preferred by the stakeholders. The evaluation concludes that rainwater harvesting is the optimal solution for direct soil salinity mitigation, as it addresses a wider range of ecosystem and human well-being benefits. Nevertheless, this merit is offset by poor financial motivation making agronomic measures more attractive to users.

    Full Text Available In this paper, we describe our efforts in providing a holistic environment for our trainee teachers at the National Institute of Education (Singapore to ‘learn by experiencing and doing’ about using technology in classroom instruction. In our deliberate attempt to move away from lecturing and teaching of discrete IT skills, we modeled various strategies that are built upon established learning theories and pedagogies. These instructional strategies include direct instruction, self-directed learning, group work, computer-mediated communication, and constructivist learning. Through these processes, our trainees also experienced the use of computers as a tool for administration, presentation, tutoring, and cognitive processing. Results from a post-module evaluation survey indicated that majority of the trainees reacted positively towards the module and that the instructional objectives of the module were achieved.

    Korea Hydro and Nuclear Power (KHNP) has been managed Nuclear Power Plant (NPP) construction projects including basic project planning, design, procurement, construction and start-up for nearly 30 years, and taken the leading role in the self-reliance program for constructing NPP. To maintain its leading position of construction technology and export it to other countries, it is more likely required to build the strong and competitive business management system to improve internal business efficiency and transparency, and also to respond to the change of external business circumstances such as electricity market opening. KHNP is implementing Enterprise Resource Planning (ERP) System as a business innovation tool to improve business efficiency, which changes the way of performing work from organizational system to process-oriented system in order to optimize the company resources to achieve above goals. This change should be made based on the results of performing Business Process Re-engineering (BPR) to maximize overall business efficiency. For the construction project management area, the establishment of Integrated Construction Information Sharing System based on Information Technology (IT) is the most important part. It makes possible to build collaboration system with 'Win-Win strategy' between the project owner and all related entities and to contribute to secure transparency and cut the project cost down. We would like to introduce our NPP Construction Project Management System, Infrastructure for Information System, Information Sharing System among construction related entities and Implementation Practices in this paper and also include the suggestions on our customary practice and subject that should be improved

    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.

    2016-12-01

    Full Text Available Recent novel approaches in myocardial perfusion single photon emission CT (SPECT have been facilitated by new dedicated high-efficiency hardware with solid-state detectors and optimized collimators. New protocols include very low-dose (1 mSv stress-only, two-position imaging to mitigate attenuation artifacts, and simultaneous dual-isotope imaging. Attenuation correction can be performed by specialized low-dose systems or by previously obtained CT coronary calcium scans. Hybrid protocols using CT angiography have been proposed. Image quality improvements have been demonstrated by novel reconstructions and motion correction. Fast SPECT acquisition facilitates dynamic flow and early function measurements. Image processing algorithms have become automated with virtually unsupervised extraction of quantitative imaging variables. This automation facilitates integration with clinical variables derived by machine learning to predict patient outcome or diagnosis. In this review, we describe new imaging protocols made possible by the new hardware developments. We also discuss several novel software approaches for the quantification and interpretation of myocardial perfusion SPECT scans.

    Assessment of ethical aspects of a technology is an important component of health technology assessment (HTA). Nevertheless, how the implementation of ethical assessment in HTA is to be organized and adapted to specific regulatory and organizational settings remains unclear. The objective of this study is to present a framework for systematic identification of ethical aspects of health technologies. Furthermore, the process of developing and adapting the framework to a specific setting is described. The framework was developed based on an inventory of existing approaches to identification and assessment of ethical aspects in HTA. In addition, the framework was adapted to the Swedish legal and organizational healthcare context, to the role of the HTA agency and to the use of non-ethicists. The framework was reviewed by a group of ethicists working in the field as well as by a wider set of interested parties including industry, interest groups, and other potential users. The framework consists of twelve items with sub-questions, short explanations, and a concluding overall summary. The items are organized into four different themes: the effects of the intervention on health, its compatibility with ethical norms, structural factors with ethical implications, and long term ethical consequences of using the intervention. In this study, a framework for identifying ethical aspects of health technologies is proposed. The general considerations and methodological approach to this venture will hopefully inspire and present important insights to organizations in other national contexts interested in making similar adaptations.

    1998-09-01

    Flat panel display (FPD) technologies have emerged with smaller depth, size, and power than the cathode ray tube technology that now dominates the display market. Liquid crystal displays in general and active matrix liquid crystal displays (AMLCD), in particular, are the FPD technology of choice. The AMLCD technology is well established has undergone dramatic improvements in the past few years, a trend which is likely to continue. In recent years some potential or want-to- be ('wanabe') alternate technologies, such as field emission displays (FED), high gain emissive displays and vacuum fluorescent displays (VFD), have received substantial investments. For example, the VFD knowledge level has reached technology status as segmented displays in automotive and instrumentation applications. Much work has been done to improve FED technology status, resulting in many attempts to build production quality prototypes. However, no FED has actually gone into production. The question still remains: how close to production are these nascent technologies? This paper will examine how fast field emission displays are progressing towards technology status, which is defined as a display technology that is incorporated in products accepted by the market. This paper will provide a status update of where FED companies are and where they may be heading. Current development programs, recent demonstrations, and possible future product offerings will be discussed.

    The demand of fossil fuels, including oil, gas, and coal has been increasing with the rapid development of developing countries such as China and India. U.S., Japan, EU, and Korea have been making efforts to transfer to low carbon and green growth economics for sustainable development. And they also have been measuring to cope with climate change and the depletion of conventional fuels. Advanced nations implemented strategic energy technology development plans to lead the future energy market. Strategic energy technology development is crucial alternative to address the energy issues. This paper analyze the relative competitiveness of hydrogen energy technologies in case of hydrogen production and storage technologies from 2006 to 2010. Hydrogen energy technology is environmentally clean technology comparing with the previous conventional energy technologies and will play a key role to solve the greenhouse gas effect. Leading nations have increasingly focused on hydrogen technology R&D. This research is carried out the relative competitiveness of hydrogen energy technologies employed by an integrated fuzzy analytic hierarchy process (Fuzzy AHP) and The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) approaches. We make four criteria, accounting for technological status, R&D budget, R&D human resource, and hydrogen infra. This research can be used as fundamental data for implementing national hydrogen energy R&D planning for energy policy-makers.

  12. A new approach for evaluating water hammer including the initial state of pressurization of the installation and fluid

    Directory of Open Access Journals (Sweden)

    G. Kaless

    2016-04-01

    Full Text Available The water hammer phenomenon is well known since the 19th century, while its mathematical formulation, by means of differential equations, is due to works of researchers such us Allievi (1903 and others from the beginning of the 20th century. The equations found in the technical publications produce a strange water hammer when the initial condition is defined assuming an incompressible fluid and a rigid pipe. The correct solution requires solving the water hammer equations for the initial state. When the finite difference method is applied, the initial state is solved by means of a set of non-linear equations. A novel approach is proposed including the initial state of pressurization into the governing equations and hence simplifying the calculus of the initial conditions. Furthermore, a critical reading of the deduction of the equations is done pointing out conceptual inconsistencies and proposing corrections.

    A 3-year strategic planning process was undertaken in Oak Ridge, Tennessee, to develop a research and technology development approach that can help guide mercury remediation in East Fork Poplar Creek (EFPC). Mercury remediation is a high priority for the US Department of Energy s (DOE s) Oak Ridge Office of Environmental Management because of large historical losses of mercury to the environment at the Y-12 National Security Complex (Y-12). Because of the extent of mercury losses and the complexities of mercury transport and fate in the stream environment, the success of conventional options for mercury remediation in the downstream sections of EFPC is uncertain. The overall Oak Ridge mercury remediation strategy focuses on mercury treatment actions at Y-12 in the short-term and research and technology development to evaluate longer-term solutions in the downstream environment. The technology development strategy is consistent with a phased, adaptive management paradigm and DOE s Technology Readiness Level guidelines. That is, early evaluation includes literature review, site characterization, and small-scale studies of a broad number of potential technologies. As more information is gathered, technologies that may have the most promise and potential remediation benefit will be chosen for more extensive and larger-scale pilot testing before being considered for remedial implementation. Field and laboratory research in EFPC is providing an improved level of understanding of mercury transport and fate processes in EFPC that will inform the development of site-specific remedial technologies. Technology development has centered on developing strategies that can mitigate the primary factors affecting mercury risks in the stream: (1) the amount of inorganic mercury available to the stream system, (2) the conversion of inorganic mercury to methylmercury, and (3) the bioaccumulation of methylmercury through the food web. Given the downstream complexities and

    2015-07-01

    Full Text Available Technology transfer, from research and technology organizations (RTOs toward local industries, is considered as one of important and significant strategies for countries' industrial development. In addition to recover the enormous costs of research and development for RTOs, successful technology transfer from RTOs toward local firms forms technological foundations and develops the ability to enhance the competitiveness of firms. Better understanding of factors influencing process of technology transfer helps RTOs and local firms prioritize and manage their resources in an effective and efficient way to maximize the success of technology transfer. This paper aims to identify important effective factors in technology transfer from Iranian RTOs and provides a comprehensive model, which indicate the interactions of these factors. In this regard, first, research background is reviewed and Cummings and Teng’s model (2003 [Cummings, J. L., & Teng, B.-S. (2003. Transferring R&D knowledge: The key factors affecting knowledge transfer success. Journal of Engineering and Technology Management, 20(1-2, 39-68.] was selected as the basic model in this study and it was modified through suggesting new factors identified from literature of inter-organizational knowledge and technology transfer and finally a Delphi method was applied for validation of modified model. Then, research conducted used Interpretive Structural Modeling (ISM to evaluate the relationship between the factors of final proposed model. Results indicate that there were twelve factors influencing on technology transfer process from Iranian RTOs to local firms and also the intensity of absorption capability in transferee could influence on the intensity of desorption capability in transferor.

    1993-01-01

    The range of tobacco control activities should be viewed as essential parts of a complex multi-component puzzle. Intervention strategies designed to address tobacco control should be comprehensive and include both primary and secondary prevention activities and be multi-faceted and capable of bringing about change at both the individual and broader social and cultural levels. In this paper I argue for a mutually inclusive framework in which the various components contribute in important and different ways. I examine the prevalence of smoking and identify the high risk groups, then I examine the range of available strategies and present the evidence for their success. I discuss the primary prevention approaches such as warning labels, taxes, price increases, workplace bans, education in schools, mass media and self-help materials, as well as brief interventions and treatment strategies which are conducted at the worksite, general practice and specialized cessation clinics. The areas for future research are delineated for increased resource allocation and include: the best ways to disseminate brief interventions to smokers, methods to motivate smokers; training of health professionals to deliver brief interventions; enhancing quitting and access to existing treatment resources among specific disadvantaged minority groups, e.g. migrants, unemployed youth, the effect on smoking prevalence of warning labels on cigarette packets and price rises on cigarettes.

    For environmental and health effects due to increasing levels of pollution in the atmosphere, it is necessary to develop environmentally sound technologies for the treatment of greenhouse gases (CO 2 , CH 4 , CFC, etc.) and acid gases (SOx, NOx, etc.). Specifically, advanced technology for CO 2 capturing is currently one of the most important environmental issues in worldwide. 14 CO 2 , specially which has been gradually emerging issue in the nuclear facilities, is generated about 330 ppm from the CANDU (Canadian Deuterium Uranium Reactor) nuclear power plant and the DUPIC (Direct Use of spent PWR fuel in CANDU reactors) process which is the process of spent fuel treatment. For this purpose, it is necessary to develop the most efficient treatment technology of CO 2 capture by various lime materials in semi- or dry process, it should be also considering a removal performance, waste recycling and safety of disposal. In order to develop a highly active slaked lime as a sorbent for CO 2 and high temperature desulfurization, macroporous slaked lime is necessarily prepared by modified swelling process and equipment, which was developed under carrying out this project. And also for the optimal removal process of off-gases the removal performance tests of various sorbents and the effects of relative humidity and bed depth on the removal capacity must be considered

  2. After Virtual Archaeology: Rethinking Archaeological Approaches to the Adoption of Digital Technology

    Directory of Open Access Journals (Sweden)

    Gareth Beale

    2017-06-01

    Full Text Available In the 1980s archaeologists embraced the rapidly expanding field of computer modelling and visualisation as a vehicle for data exploration. Against this backdrop 'virtual archaeology' was conceived. The term was originally intended to describe a multidimensional approach to the modelling of the (immaterial structures and processes of field archaeology. It described how technology could be harnessed in order to achieve new ways of documenting, interpreting and annotating primary archaeological discoveries and processes. Despite their initial promise, these digital technologies failed to have the impact upon archaeological fieldwork that might have been expected. Even with the prevalence of digital devices on all archaeological excavations, the documentation, interpretation and subsequent narration of archaeological processes have retained their analogue character. While the archaeological record is now primarily digital, its sections, plans, drawings and photographs are facsimiles of the analogue technologies that preceded them. This retention of analogue conventions is increasingly out of step with the general prevalence and diversity of digital technologies as mediators of professional and private life. It is also challenged by 21st-century advances towards technologies that allow for complex engagements with and representations of physical matter and facilitate the interplay between digital and material worlds. This article argues that emerging forms of archaeological practice including gaming, mixed reality, computational photography and additive manufacturing, reveal digital archaeology to be a creative process, blending computational thinking, technological opportunities and established disciplinary traditions. We go on to suggest that digital archaeology, conceived as a form of practice rather than as a toolset, represents a locus for theory generation and critical thinking.

    The Graphical Unitary Group Approach (GUGA) was cast into an extraordinarily powerful form by restructuring the Hamiltonian in terms of loop types. This restructuring allows the adoption of the loop-driven formulation which illuminates vast numbers of previously unappreciated relationships between otherwise distinct Hamiltonian matrix elements. The theoretical/methodological contributions made here include the development of the loop-driven formula generation algorithm, a solution of the upper walk problem used to develop a loop breakdown algorithm, the restriction of configuration space employed to the multireference interacting space, and the restructuring of the Hamiltonian in terms of loop types. Several other developments are presented and discussed. Among these developments are the use of new segment coefficients, improvements in the loop-driven algorithm, implicit generation of loops wholly within the external space adapted within the framework of the loop-driven methodology, and comparisons of the diagonalization tape method to the direct method. It is also shown how it is possible to implement the GUGA method without the time-consuming full (m 5 ) four-index transformation. A particularly promising new direction presented here involves the use of the GUGA methodology to obtain one-electron and two-electron density matrices. Once these are known, analytical gradients (first derivatives) of the CI potential energy are easily obtained. Several test calculations are examined in detail to illustrate the unique features of the method. Also included is a calculation on the asymmetric 2 1 A' state of SO 2 with 23,613 configurations to demonstrate methods for the diagonalization of very large matrices on a minicomputer. 6 figures, 6 tables

    Pregnancy rates after frozen embryo transfer (FET) have improved in recent years and are now approaching or even exceeding those obtained after fresh embryo transfer. This is partly due to improved laboratory techniques, but may also be caused by a more physiological hormonal and endometrial environment in FET cycles. Furthermore, the risk of ovarian hyperstimulation syndrome is practically eliminated in segmentation cycles followed by FET and the use of natural cycles in FETs may be beneficial for the postimplantational conditions of fetal development. However, a freeze-all strategy is not yet implemented as standard care due to limitations of large randomised trials showing a benefit of such a strategy. Thus, there is a need to test the concept against standard care in a randomised controlled design. This study aims to compare ongoing pregnancy and live birth rates between a freeze-all strategy with gonadotropin-releasing hormone (GnRH) agonist triggering versus human chorionic gonadotropin (hCG) trigger and fresh embryo transfer in a multicentre randomised controlled trial. Multicentre randomised, controlled, double-blinded trial of women undergoing assisted reproductive technology treatment including 424 normo-ovulatory women aged 18-39 years from Denmark and Sweden. Participants will be randomised (1:1) to either (1) GnRH agonist trigger and single vitrified-warmed blastocyst transfer in a subsequent hCG triggered natural menstrual cycle or (2) hCG trigger and single blastocyst transfer in the fresh (stimulated) cycle. The primary endpoint is to compare ongoing pregnancy rates per randomised patient in the two treatment groups after the first single blastocyst transfer. The study will be performed in accordance with the ethical principles in the Helsinki Declaration. The study is approved by the Scientific Ethical Committees in Denmark and Sweden. The results of the study will be publically disseminated. NCT02746562; Pre-results. © Article author(s) (or their

    To date, methodologies are lacking that address a holistic assessment of wellness in older adults. Technology applications may provide a platform for such an assessment, but have not been validated. We set out to demonstrate whether e-health applications could support the assessment of older adults' wellness in community-dwelling older adults. Twenty-seven residents of independent retirement community were followed over 8 weeks. Subjects engaged in the use of diverse technologies to assess cognitive performance, physiological and functional variables, as well as psychometric components of wellness. Data were integrated from various e-health sources into one study database. Correlations were assessed between different parameters, and hierarchical cluster analysis was used to explore the validity of the wellness model. We found strong associations across multiple parameters of wellness within the conceptual model, including cognitive, functional, and physical. However, spirituality did not correlate with any other parameter studied in contrast to prior studies of older adults. Participants expressed overall positive attitudes toward the e-health tools and the holistic approach to the assessment of wellness, without expressing any privacy concerns. Parameters were highly correlated across multiple domains of wellness. Important clusters were noted to be formed across cognitive and physiological domains, giving further evidence of need for an integrated approach to the assessment of wellness. This finding warrants further replication in larger and more diverse samples of older adults to standardize and deploy these technologies across population groups.

    To promote the succession of history of and the creative use of industrial science technologies, the paper made lists and databases of the articles of industrial technology museums and material halls in Japan. Record/preservation and collection/systematization of history of the industrial technology is useful for forming bases necessary for promotion of future research/development and international contribution. Museums and material halls are the fields for making comprehensive and practical activities. The data were made as one of the basic databases as the first step for promoting activities for examining the technical succession situation in a long term range continuously and systematically. In the classification of the data, the energy relation was divided into electric power, nuclear power, oil, coal, gas and energy in general. Others were classified into metal/mine, electricity/electronics/communication, chemistry/food, ship building/heavy machinery, printing/precision instrument, and textile/spinning. Moreover, the traffic relation was classified into railroad, automobiles/two-wheeled vehicles, airline/space, and ships. Items were also set of life relation, civil engineering/architecture, and general. The total number of the museums for the survey reached 208.

    2014-10-01

    Current clinical approaches to melanoma diagnosis have not been associated with a decrease in mortality from this cancer. The components of the new approach presented are, first, a screening examination to look for any lesion that stands out because of being dark, different, or changing; second, when a single lesion is recognized to be of concern for any reason, that lesion is then evaluated in more detail utilizing the ABCDE criteria, with the "D" signifying "Dark" and not "6 mm Diameter" in this mnemonic; and, third, additional discussion of the "ugly duckling" sign and of the recognition of nodular melanomas. Since the Georgia Society of Dermatology and Dermatologic Surgery was the first state or national society to endorse this approach, I refer to it as the Georgia approach.

    For the past number of years, academic entrepreneurship has become one of the most widely studied topics in the entrepreneurship literature. Yet, despite all the research that has been conducted to date, there has not been a systematic attempt to analyze critically the factors which lie behind successful business spin-offs from university research. In this book, a group of academic thought-leaders in the field of technology transfer examine a number of areas critical to the promotion of start-ups on campus. Through a series of case studies, they examine current policies, structures, program initiatives and practices of fourteen international universities to develop a theory of successful academic entrepreneurship, with the aim of helping other universities to enhance the quality of their university transfer programs. This book is a valuable resource for researchers and graduate students working on innovation, entrepreneurship and technology transfer, as well as senior managers and policymakers.

  4. An approach to including protein quality when assessing the net contribution of livestock to human food supply.

    Ertl, P; Knaus, W; Zollitsch, W

    2016-11-01

    The production of protein from animal sources is often criticized because of the low efficiency of converting plant protein from feeds into protein in the animal products. However, this critique does not consider the fact that large portions of the plant-based proteins fed to animals may be human-inedible and that the quality of animal proteins is usually superior as compared with plant proteins. The aim of the present study was therefore to assess changes in protein quality in the course of the transformation of potentially human-edible plant proteins into animal products via livestock production; data from 30 Austrian dairy farms were used as a case study. A second aim was to develop an approach for combining these changes with quantitative aspects (e.g. with the human-edible feed conversion efficiency (heFCE), defined as kilogram protein in the animal product divided by kilogram potentially human-edible protein in the feeds). Protein quality of potentially human-edible inputs and outputs was assessed using the protein digestibility-corrected amino acid score and the digestible indispensable amino acid score, two methods proposed by the Food and Agriculture Organization of the United Nations to describe the nutritional value of proteins for humans. Depending on the method used, protein scores were between 1.40 and 1.87 times higher for the animal products than for the potentially human-edible plant protein input on a barn-gate level (=protein quality ratio (PQR)). Combining the PQR of 1.87 with the heFCE for the same farms resulted in heFCE×PQR of 2.15. Thus, considering both quantity and quality, the value of the proteins in the animal products for human consumption (in this case in milk and beef) is 2.15 times higher than that of proteins in the potentially human-edible plant protein inputs. The results of this study emphasize the necessity of including protein quality changes resulting from the transformation of plant proteins to animal proteins when

    A 58-year-old man with metastatic radioiodine-refractory differentiated thyroid cancer (DTC) presented with left thigh and right flank numbness. He had known progressive and widespread bony metastases, for which he received palliative radiotherapy, and multiple bilateral asymptomatic pulmonary metastases. CT scan and MRI of the spine revealed metastases at right T10-L1 vertebrae with extension into the central canal and epidural disease at T10 and T11 causing cord displacement and canal stenosis but retention of spinal cord signal. Spinal surgery was followed by palliative radiotherapy resulting in symptom resolution. Two months later, sorafenib received approval for use in Australia and was commenced and up-titrated with symptomatic management of mild adverse effects. Follow-up CT scan three months after commencement of sorafenib revealed regression of pulmonary metastases but no evident change in most bone metastases except for an advancing lesion eroding into the right acetabulum. The patient underwent a right total hip replacement, intra-lesional curettage and cementing. After six months of sorafenib therapy, CT scanning showed enlarging liver lesions with marked elevation of serum thyroglobulin. Lenvatinib was commenced and sorafenib was ceased. He now has stable disease with a falling thyroglobulin more than 5 years after metastatic radioiodine-refractory DTC was diagnosed. In DTC, 5% of distant metastases become radioiodine-refractory, resulting in a median overall survival of 2.5-3.5 years. Tyrosine kinase inhibitor (TKI) therapy has recently been demonstrated to increase progression-free survival in these patients but poses some unique management issues and is best used as part of an integrated approach with directed therapy. Directed therapies may have greater potential to control localised disease and related symptoms when compared to systemic therapies.Consider TKI therapy in progressive disease where benefits outweigh risks.Active surveillance and

    Young children are using digital technology (DT) devices anytime and anywhere, especially with the invention of smart phones and the replacement of desktop computers with digital tablets. Although research has shown that parents play an important role in fostering and supporting preschoolers' developing maturity and decisions about DT use, and in protecting them from potential risk due to excessive DT exposure, there have been limited studies conducted in Hong Kong focusing on parent-child DT use. This study had three objectives: 1) to explore parental use of DTs with their preschool children; 2) to identify the DT content that associated with child behavioral problems; and 3) to investigate the relationships between approaches adopted by parents to control children's DT use and related preschooler behavioral problems. This exploratory quantitative study was conducted in Hong Kong with 202 parents or guardians of preschool children between the ages of 3 and 6 attending kindergarten. The questionnaire was focused on four aspects, including 1) participants' demographics; 2) pattern of DT use; 3) parenting approach to manage the child's DT use; and 4) child behavioral and health problems related to DT use. Multiple regression analysis was adopted as the main data analysis method for identifying the DT or parental approach-related predictors of the preschooler behavioral problems. In the multiple linear regression model, the 'restrictive approach score' was the only predictor among the three parental approaches (B:1.66, 95% CI: [0.21, 3.11], p parents play a crucial role in fostering appropriate and safe DT use. It is suggested that parents practice a combination of restrictive, instructive and co-using approaches, rather than a predominately restrictive approach, to facilitate their child's growth and development. Further studies are needed to explore the parent-child relationship and parents' self-efficacy when managing the parent-child DT use, to develop

  7. Technology decision making. A constructive approach to planning and acquisition will require a paradigm shift.

    Technology should be viewed as an integrating rather than a divisive element in hospital planning. In the past, technology decision-making responsibility has often been diffused throughout hospitals, but providers are beginning to take a more considered and coherent approach. The process of making decisions about technology has four key elements: assessment, planning, acquisition, and management. The most important aspect of the assessment phase is the formation of a technology advisory committee to review and evaluate requests for new and emerging technology; review capital budget requests for new and replacement technology; and set mission-based and strategic priorities for new, emerging, and replacement technologies. Technology planning allows hospitals to set long-term goals for technology acquisition. The process involves an audit of existing technologies, evaluation of other hospitals' technologies, and review of technology trends. A well-defined technology plan will, in turn, facilitate the acquisition and management process, allowing hospitals greater flexibility in negotiating costs and budgeting for training, spare parts, service, upgrades, and support. By pooling resources with other providers in their region, hospitals can further enhance the effectiveness of their use and acquisition of technology. Collaboration allows providers to share the risks of technologically volatile and intensive services and avoid costly duplication of equipment and facilities.

    Full Text Available The purpose of this paper is to justify the role of integrated approach to music education of students. This requires the implementation of a theoretical analysis of the meaning and importance of an integrated approach to music education and training, determination of didactic conditions of integrating the music education in schools and coverage of methods of arrangement of the complex relationships of the main types of educational and creative activity for students in music lessons. It is proved that an integrated approach to the music education process causes the appearance of new original teaching forms and techniques that brings the process to a new qualitative level, enriching the musical and creative abilities of students, enabling them to realize the artistic and aesthetic taste preferences, to achieve the integrity of musical and creative development and high levels of formation of aesthetic consciousness and music.

    In recent years, Russia adopted a policy towards increasing of the share of renewable energy in total amount of used energy, albeit with some delay comparing to the EU countries and the USA. It was expected that the use of biofuels over time will reduce significantly the dependency of Russian economy on fossil fuels, increase its competitiveness, and increase Russian contribution to the prevention of global climate changes. Russia has significant bio-energy potential and resources which are characterized by great diversity due to the large extent of the territory, which require systematic studies and environmental assessment of used bio-energy technologies. Results of research carried at the Laboratory of agroecological monitoring, modeling and prediction of ecosystems RSAU-MTAA demonstrated significant differences in the assessment of the environmental, economic and social effects of biofuel production and use, depending on the species of bio-energy crops, regional soil-ecological and agro-climatic characteristics, applied farming systems and production processes. The total area of temporarily unused and fallow land, which could be allocated to the active agricultural use in Russia, according to various estimates, ranges from 20 to 33 million hectares, which removes the problem, typical of most European countries, of adverse agro-ecological changes in land use connected with the expansion of bio-energy crops cultivation. However, the expansion of biofuel production through the use of fallow land and conversion of natural lands has as a consequence the problem of greenhouse gas emissions due to land use changes, which, according to FAO, could be even higher than CO2 emission from fossil fuels for some of bio-energy raw materials and production systems. Assessment of the total impacts of biofuels on greenhouse gas emissions in the Russian conditions should be based on regionally adapted calculations of flows throughout the entire life cycle of production, taking

  11. Fake News: A Technological Approach to Proving the Origins of Content, Using Blockchains.

    Huckle, Steve; White, Martin

    2017-12-01

    In this article, we introduce a prototype of an innovative technology for proving the origins of captured digital media. In an era of fake news, when someone shows us a video or picture of some event, how can we trust its authenticity? It seems that the public no longer believe that traditional media is a reliable reference of fact, perhaps due, in part, to the onset of many diverse sources of conflicting information, via social media. Indeed, the issue of "fake" reached a crescendo during the 2016 U.S. Presidential Election, when the winner, Donald Trump, claimed that The New York Times was trying to discredit him by pushing disinformation. Current research into overcoming the problem of fake news does not focus on establishing the ownership of media resources used in such stories-the blockchain-based application introduced in this article is technology that is capable of indicating the authenticity of digital media. Put simply, using the trust mechanisms of blockchain technology, the tool can show, beyond doubt, the provenance of any source of digital media, including images used out of context in attempts to mislead. Although the application is an early prototype and its capability to find fake resources is somewhat limited, we outline future improvements that would overcome such limitations. Furthermore, we believe that our application (and its use of blockchain technology and standardized metadata) introduces a novel approach to overcoming falsities in news reporting and the provenance of media resources used therein. However, while our application has the potential to be able to verify the originality of media resources, we believe that technology is only capable of providing a partial solution to fake news. That is because it is incapable of proving the authenticity of a news story as a whole. We believe that takes human skills.

    2016-11-01

    Full Text Available Flood protection systems with their spatial effects play an important role in managing and reducing flood risks. The planning and decision process as well as the technical implementation are well organized and often exercised. However, building-related flood-resilience technologies (FReT are often neglected due to the absence of suitable approaches to analyse and to integrate such measures in large-scale flood damage mitigation concepts. Against this backdrop, a synthetic model-approach was extended by few complementary methodical steps in order to calculate flood damage to buildings considering the effects of building-related FReT and to analyse the area-related reduction of flood risks by geo-information systems (GIS with high spatial resolution. It includes a civil engineering based investigation of characteristic properties with its building construction including a selection and combination of appropriate FReT as a basis for derivation of synthetic depth-damage functions. Depending on the real exposition and the implementation level of FReT, the functions can be used and allocated in spatial damage and risk analyses. The application of the extended approach is shown at a case study in Valencia (Spain. In this way, the overall research findings improve the integration of FReT in flood risk management. They provide also some useful information for advising of individuals at risk supporting the selection and implementation of FReT.

    Though the proportion of older population is growing and the number of people with long-term conditions is increasing, there is unlikely to be enough caregivers for those older people or people with long-term conditions who wish to live at home. Thus how to ensure sufficient caregiving events to meet the growing demand in home healthcare sector becomes a challenge. A collaborative software prototype utilising smartphone technology has been proposed in this study to provide coordinated caregiving. The system in future may both spread the load among family caregivers and professional caregivers while ensuring that the patient's needs are always covered.

    2013-04-01

    Full Text Available With the popularization of smartphones, location-based services are increasingly part of everyday live. People use their cell phones to find nearby restaurants, friends in the vicinity, and track their children. Although location-based services have received sparse attention from mobile communications cholars to date, the ability of locating people and things with one’s cell phone is not new. Since the removal of GPS signal degradation in 2000, artists and researchers have been exploring how location-awareness influences mobility, spatiality and sociability. Besides exploring the historical antecedents of today’s location-based services, this paper focuses on the main social issues that emerge when location-aware technologies leave the strict domain of art and research and become part of everyday life: locational privacy, sociability, and spatiality. Finally, this paper addresses two main topics that future mobile communication research that focus on location-awareness should take into consideration: a shift in the meaning of location, and the adoption and appropriation of location-aware technologies in the global south.

    Epigenetics refers to the collection of heritable features that modulate the genome-environment interaction without being encoded in the actual DNA sequence. While being mitotically and sometimes even meiotically transmitted, epigenetic traits often demonstrate extensive flexibility. This allows cells to acquire diverse gene expression patterns during differentiation, but also to adapt to a changing environment. However, epigenetic alterations are not always beneficial to the organism, as they are, for example, frequently identified in human diseases such as cancer. Accurate and cost-efficient genome-scale profiling of epigenetic features is thus of major importance to pinpoint these "epimutations," for example, to monitor the epigenetic impact of environmental exposure. Over the last decade, the field of epigenetics has been revolutionized by several innovative "epigenomics" technologies exactly addressing this need. In this review, we discuss and compare widely used next-generation methods to assess DNA methylation and hydroxymethylation, noncoding RNA expression, histone modifications, and nucleosome positioning. Although recent methods are typically based on "second-generation" sequencing, we also pay attention to still commonly used array- and PCR-based methods, and look forward to the additional advantages of single-molecule sequencing. As the current bottleneck in epigenomics research is the analysis rather than generation of data, the basic difficulties and problem-solving strategies regarding data preprocessing and statistical analysis are introduced for the different technologies. Finally, we also consider the complications associated with epigenomic studies of species with yet unsequenced genomes and possible solutions. Copyright © 2013 Wiley Periodicals, Inc.

    Full Text Available As fragile food commodities, microbial, and organoleptic qualities of fishery and seafood can quickly deteriorate. In this context, microbial quality and security improvement during the whole food processing chain (from catch to plate, using hurdle technology, a combination of mild preserving technologies such as biopreservation, modified atmosphere packaging, and superchilling, are of great interest. As natural flora and antimicrobial metabolites producers, lactic acid bacteria (LAB are commonly studied for food biopreservation. Thirty-five LAB known to possess interesting antimicrobial activity were selected for their potential application as bioprotective agents as a part of hurdle technology applied to fishery products. The selection approach was based on seven criteria including antimicrobial activity, alteration potential, tolerance to chitosan coating, and superchilling process, cross inhibition, biogenic amines production (histamine, tyramine, and antibiotics resistance. Antimicrobial activity was assessed against six common spoiling bacteria in fishery products (Shewanella baltica, Photobacterium phosphoreum, Brochothrix thermosphacta, Lactobacillus sakei, Hafnia alvei, Serratia proteamaculans and one pathogenic bacterium (Listeria monocytogenes in co-culture inhibitory assays miniaturized in 96-well microtiter plates. Antimicrobial activity and spoilage evaluation, both performed in cod and salmon juice, highlighted the existence of sensory signatures and inhibition profiles, which seem to be species related. Finally, six LAB with no unusual antibiotics resistance profile nor histamine production ability were selected as bioprotective agents for further in situ inhibitory assays in cod and salmon based products, alone or in combination with other hurdles (chitosan, modified atmosphere packing, and superchilling.

  5. Modifying the Sleep Treatment Education Program for Students to include technology use (STEPS-TECH): Intervention effects on objective and subjective sleep outcomes.

    Barber, Larissa K; Cucalon, Maria S

    2017-12-01

    University students often have sleep issues that arise from poor sleep hygiene practices and technology use patterns. Yet, technology-related behaviors are often neglected in sleep hygiene education. This study examined whether the Sleep Treatment Education Program for Students-modified to include information regarding managing technology use (STEPS-TECH)-helps improve both subjective and objective sleep outcomes among university students. Results of an experimental study among 78 university students showed improvements in objective indicators of sleep quantity (total sleep time) and sleep quality (less awakenings) during the subsequent week for students in the STEPS-TECH intervention group compared to a control group. Exploratory analyses indicated that effects were driven by improvements in weekend days immediately following the intervention. There were also no intervention effects on subjective sleep quality or quantity outcomes. In terms of self-reported behavioral responses to educational content in the intervention, there were no group differences in sleep hygiene practices or technology use before bedtime. However, the intervention group reported less technology use during sleep periods than the control group. These preliminary findings suggest that STEPS-TECH may be a useful educational tool to help improve objective sleep and reduce technology use during sleep periods among university students.

    Pervasive healthcare support through mobile information technology solutions is playing an increasing role in the attempt to improve healthcare and reduce costs. Despite the apparent attractiveness, many mobile applications have failed or have not been implemented as predicted. Among factors possibly leading to such outcomes, technology adoption is a key problem. This must be investigated early in the development process because healthcare is a particularly sensitive area with vital social implications. Moreover, it is important to investigate technology acceptance using the support of scientific tools validated for relevant information systems research. This article presents an empirical study based on the Technology Acceptance Model 2 in mobile homecare nursing. The study elicited the perceptions of 91 Canadian nurses who used personal digital assistants for 1 month in their daily activities. A partial least squares modeling data analysis revealed that nurse's perception of usefulness is the main factor in the adoption of mobile technology, having subjective norm and image within the organization as significant antecedents. Overall, this study was the first attempt at investigating scientifically, through a pertinent information systems research model, user adoption of mobile systems by homecare nursing personnel.

  8. Technology information transfer in public outreach - a new approach

    The timely and accurate dissemination to the public of information derived from the site characterization activities on the Yucca Mountain Site Characterization Project (YMP) has sometimes been difficult to achieve. The YMP has many participants who are involved in the gathering and analysis of scientific and engineering data for site characterization. The diversity of the scientific disciplines involved, the uncentralized location of the participant organizations, the difficulty of being able to ask the right questions of the right people, and the translation of technical jargon into understandable terms are but a few of the challenges. The public outreach program of the YMP has done an excellent job of compiling and distributing information over the past few years, but, with the diversity and expansion of field activities in the last two years, the job has become more formidable. A new approach to help resolve this obstacle was instituted in April of 1993, and has been successful in achieving a much more timely and user-friendly discussion of technical information for the public. What is the new approach? The assignment of a technical expert to the public outreach staff whose job is to know what is going on, who is doing what, and what the results are. Based on that knowledge, factual summaries can be generated rapidly and presented to the public in the context of the overall project goals and in a form suitable for a wide range of audiences

  9. Near-term technology policies for long-term climate targets--economy wide versus technology specific approaches

    Sanden, B.A.; Azar, Christian

    2005-01-01

    The aim of this paper is to offer suggestions when it comes to near-term technology policies for long-term climate targets based on some insights into the nature of technical change. We make a distinction between economy wide and technology specific policy instruments and put forward two key hypotheses: (i) Near-term carbon targets such as the Kyoto protocol can be met by economy wide price instruments (carbon taxes, or a cap-and-trade system) changing the technologies we pick from the shelf (higher energy efficiency in cars, buildings and industry, wind, biomass for heat and electricity, natural gas instead of coal, solar thermal, etc.). (ii) Technology specific policies are needed to bring new technologies to the shelf. Without these new technologies, stricter emission reduction targets may be considered impossible to meet by the government, industry and the general public, and therefore not adopted. The policies required to bring these more advanced technologies to the shelf are more complex and include increased public research and development, demonstration, niche market creation, support for networks within the new industries, standard settings and infrastructure policies (e.g., when it comes to hydrogen distribution). There is a risk that the society in its quest for cost-efficiency in meeting near-term emissions targets, becomes blindfolded when it comes to the more difficult, but equally important issue of bringing more advanced technologies to the shelf. The paper presents mechanisms that cause technology look in, how these very mechanisms can be used to get out of the current 'carbon lock-in' and the risk with premature lock-ins into new technologies that do not deliver what they currently promise. We then review certain climate policy proposals with regards to their expected technology impact, and finally we present a let-a-hundred-flowers-bloom strategy for the next couple of decades

    There are many similarities between research on combinatorial chemistry and natural products and research on dietary supplements and botanicals in the NIH Botanical Research Centers. The technologies in the centers are similar to those used by other NIH-sponsored investigators. All centers rigorously examine the authenticity of botanical dietary supplements and determine the composition and concentrations of the phytochemicals therein, most often by liquid chromatography–mass spectrometry. Several of the centers specialize in fractionation and high-throughput evaluation to identify the individual bioactive agent or a combination of agents. Some centers are using DNA microarray analyses to determine the effects of botanicals on gene transcription with the goal of uncovering the important biochemical pathways they regulate. Other centers focus on bioavailability and uptake, distribution, metabolism, and excretion of the phytochemicals as for all xenobiotics. Because phytochemicals are often complex molecules, synthesis of isotopically labeled forms is carried out by plant cells in culture, followed by careful fractionation. These labeled phytochemicals allow the use of accelerator mass spectrometry to trace the tissue distribution of 14C-labeled proanthocyanidins in animal models of disease. State-of-the-art proteomics and mass spectrometry are also used to identify proteins in selected tissues whose expression and posttranslational modification are influenced by botanicals and dietary supplements. In summary, the skills needed to carry out botanical centers’ research are extensive and may exceed those practiced by most NIH investigators. PMID:18258642

    Full Text Available High-tech companies are rapidly growing in the world. Research and development (hereafter R&D department strength is the main asset that allows a firm to achieve a competitive advantage in high-tech businesses. The allocated budget to this sector is finite; thus, integration, human resource, risk and budget limitations should be considered to choose the most valuable project in the best portion of time. This paper investigates a case study from a high-tech company in Iran to prioritize the most attractive technologies for the R&D department. The case consists of twenty three technology options and the goal is to find the most attractive projects to sort them out for implementation in the R&D department. In this research, scholars proposed the best–worst method (henceforth BWM to find the weight of the criteria of the attractive technologies in first step and utilize the newly developed method total area based on orthogonal vectors (henceforward TAOV to sort the selected technologies based upon the identified criteria. Project integration is one of the least-noticed subjects in scientific papers; therefore, the researchers presented a zero or one linear programming (ZOLP model to optimize and schedule the implementation procedure on the project risk, budget and time limitation simultaneously. The results indicate that starting few but attractive projects in the first years and postponing the rest to the future, helps a firm to manage funds and gain profit with the least amount of risk.

    Traumatic brain injury (TBI) has become the signature injury of Operation Iraqi Freedom and Operation Enduring Freedom. The use of improvised explosive devices has seen an exponential increase in both Iraq and Afghanistan. In previous conflicts prior to Iraq, survivability of such an injury was far less. Today, technological improvements in trauma care have increased an injured warfighter's chance of survival. A reduction in severe TBI has been achieved but an increase in mild or moderate TBI has been observed. The consequences of this kind of injury can be both physical and mental and can often be hidden or even misdiagnosed. The U.S. Army is interested in pursuing technological solutions for early detection and treatment of TBI to reduce its lasting impact on the warfighter. Such technological breakthroughs have benefit beyond the military, as TBI is a high probable event in nonmilitary settings as well. To gauge what technologies or methods are currently available, the U.S. Army's Telemedicine and Advanced Technology Research Center partnered with the American Telemedicine Association to organize and conduct a discipline-specific symposium entitled "Innovative New Technologies to Identify and Treat Traumatic Brain Injuries: Crossover Technologies and Approaches Between Military and Civilian Applications." This symposium was held in Palm Springs, CA, in September 2009. The purpose of the meeting was to provide a unique opportunity for leaders from disparate organizations involved in telemedicine and related other activities to meet and explore opportunities to collaborate in new partnership models. The meeting was designed to help Telemedicine and Advanced Technology Research Center identify opportunities to expand strategic operations and form new alliances. This report summarizes this symposium while raising awareness for collaboration into better ways of adapting and adopting technologies to address this growing health issue.

  14. Quantum wavepacket ab initio molecular dynamics: an approach for computing dynamically averaged vibrational spectra including critical nuclear quantum effects.

    Sumner, Isaiah; Iyengar, Srinivasan S

    2007-10-18

    We have introduced a computational methodology to study vibrational spectroscopy in clusters inclusive of critical nuclear quantum effects. This approach is based on the recently developed quantum wavepacket ab initio molecular dynamics method that combines quantum wavepacket dynamics with ab initio molecular dynamics. The computational efficiency of the dynamical procedure is drastically improved (by several orders of magnitude) through the utilization of wavelet-based techniques combined with the previously introduced time-dependent deterministic sampling procedure measure to achieve stable, picosecond length, quantum-classical dynamics of electrons and nuclei in clusters. The dynamical information is employed to construct a novel cumulative flux/velocity correlation function, where the wavepacket flux from the quantized particle is combined with classical nuclear velocities to obtain the vibrational density of states. The approach is demonstrated by computing the vibrational density of states of [Cl-H-Cl]-, inclusive of critical quantum nuclear effects, and our results are in good agreement with experiment. A general hierarchical procedure is also provided, based on electronic structure harmonic frequencies, classical ab initio molecular dynamics, computation of nuclear quantum-mechanical eigenstates, and employing quantum wavepacket ab initio dynamics to understand vibrational spectroscopy in hydrogen-bonded clusters that display large degrees of anharmonicities.

    A key element to improved industry productivity is effective management of Computer Aided Design / Computer Aided Manufacturing (CAD/CAM) information. To stimulate advancement, a unique joint government/industry project designated Integrated Programs for Aerospace-Vehicle Design (IPAD) was carried out from 1971 to 1984. The goal was to raise aerospace industry productivity through advancement of computer based technology to integrate and manage information involved in the design and manufacturing process. IPAD research was guided by an Industry Technical Advisory Board (ITAB) composed of over 100 representatives from aerospace and computer companies. The project complemented traditional NASA/DOD research to develop aerospace design technology and the Air Force's Integrated Computer Aided Manufacturing (ICAM) program to advance CAM technology. IPAD had unprecedented industry support and involvement and served as a unique approach to government industry cooperation in the development and transfer of advanced technology. The IPAD project background, approach, accomplishments, industry involvement, technology transfer mechanisms and lessons learned are summarized.

    This study reported Grade 7 students' normative decision making in teaching and learning about global warming through science technology and society (STS) approach. The participants were 43 Grade 7 students in Sungkom, Nongkhai, Thailand. The teaching and learning about global warming through STS approach had carried out for 5 weeks. The global warming unit through STS approach was developed based on framework of Yuenyong (2006) that consisted of five stages including (1) identification of social issues, (2) identification of potential solutions, (3) need for knowledge, (4) decision-making, and (5) socialization stage. Students' normative decision making was collected during their learning by questionnaire, participant observation, and students' tasks. Students' normative decision making were analyzed from both pre-and post-intervention and students' ideas during the intervention. The aspects of normative include influences of global warming on technology and society; influences of values, culture, and society on global warming; and influences of technology on global warming. The findings revealed that students have chance to learn science concerning with the relationship between science, technology, and society through their giving reasons about issues related to global warming. The paper will discuss implications of these for science teaching and learning through STS in Thailand.

    We have applied the multicoefficient density functional theory (MC-DFT) to four recent Minnesota functionals, including M06-2X, M08-HX, M11, and MN12-SX on the performance of thermochemical kinetics. The results indicated that the accuracy can be improved significantly using more than one basis set. We further included the SCS-MP2 energies into MC-DFT, and the resulting mean unsigned errors (MUEs) decreased by approximately 0.3 kcal/mol for the most accurate basis set combinations. The M06-2X functional with the simple [6-311+G(d,p)/6-311+G(2d,2p)] combination gave the best performance/cost ratios for the MC-DFT and MC-SCS-MP2|MC-DFT methods with MUE of 1.58 and 1.22 kcal/mol, respectively.

    A two-step solution based on the boundary conditions of Crank's equations for mass transfer in a film was developed. Three driving factors, the diffusion (D), partition (K p,f ) and convective mass transfer coefficients (h), govern the sorption and/or desorption kinetics of migrants from polymer films. These three parameters were simultaneously estimated. They provide in-depth insight into the physics of a migration process. The first step was used to find the combination of D, K p,f and h that minimized the sums of squared errors (SSE) between the predicted and actual results. In step 2, an ordinary least square (OLS) estimation was performed by using the proposed analytical solution containing D, K p,f and h. Three selected migration studies of PLA/antioxidant-based films were used to demonstrate the use of this two-step solution. Additional parameter estimation approaches such as sequential and bootstrap were also performed to acquire a better knowledge about the kinetics of migration. The proposed model successfully provided the initial guesses for D, K p,f and h. The h value was determined without performing a specific experiment for it. By determining h together with D, under or overestimation issues pertaining to a migration process can be avoided since these two parameters are correlated. Copyright © 2017 Elsevier Ltd.

    Full Text Available Graphene aerogels (GAs have attracted extensive interest in diverse fields, owing to their ultrahigh surface area, low density and decent electrical conductivity. However, the undesirable thermal conductivity of GAs may limit their applications in energy storage devices. Here, we report a facile hydrothermal method to modulate both the electrical and thermal properties of GAs by including bulk molybdenum disulfide (MoS2. It was found that MoS2 can help to reduce the size of graphene sheets and improve their dispersion, leading to the uniform porous micro-structure of GAs. The electrical measurement showed that the electrical conductivity of GAs could be decreased by 87% by adding 0.132 vol % of MoS2. On the contrary, the thermal conductivity of GAs could be increased by ~51% by including 0.2 vol % of MoS2. The quantitative investigation demonstrated that the effective medium theories (EMTs could be applied to predict the thermal conductivity of composite GAs. Our findings indicated that the electrical and thermal properties of GAs can be tuned for the applications in various fields.

    Exploration technology roadmaps have been developed by ESA in the past few years and the latest edition has been released in 2015. Scope of these technology roadmaps, elaborated in consultation with the different ESA stakeholders (e.g. European Industries and Research Entities), is to provide a powerful tool for strategic, programmatic and technical decisions in support of the European role within an International Space Exploration context. In the context of preparation for possible future European Moon exploration initiatives, the technology roadmaps have been used to highlight the role of technology within Missions, Building Blocks and Operational Capabilities of relevance. In particular, as part of reference missions to the Moon that would fit in the time frame 2020 to 2030, ESA has addressed the definition of lunar surface exploration missions in line with its space exploration strategy, with the common mission goals of returning samples from the Moon and Mars and expanding human presence to these destinations in a step-wise approach. The roadmaps for the procurement of technologies required for the first mission elements of the above strategy have been elaborated through their main building blocks, i.e. Visual navigation, Hazard detection and avoidance; Sample acquisition, processing and containment system; Surface mobility elements; Tele-robotic and autonomous control systems; and Storable propulsion modules and equipment. Technology prioritization methodologies have been developed in support of the ESA Exploration Technology Roadmaps, in order to provide logical and quantitative instruments to verify choices of prioritization that can be carried out based on important, but non-quantitative factors. These methodologies, which are thoroughly described in the first part of the paper, proceed through subsequent steps. First, technology prioritization's criteria are selected; then decision trees are developed to highlight all feasible paths of combination of

    Full Text Available A 58-year-old man with metastatic radioiodine-refractory differentiated thyroid cancer (DTC presented with left thigh and right flank numbness. He had known progressive and widespread bony metastases, for which he received palliative radiotherapy, and multiple bilateral asymptomatic pulmonary metastases. CT scan and MRI of the spine revealed metastases at right T10–L1 vertebrae with extension into the central canal and epidural disease at T10 and T11 causing cord displacement and canal stenosis but retention of spinal cord signal. Spinal surgery was followed by palliative radiotherapy resulting in symptom resolution. Two months later, sorafenib received approval for use in Australia and was commenced and up-titrated with symptomatic management of mild adverse effects. Follow-up CT scan three months after commencement of sorafenib revealed regression of pulmonary metastases but no evident change in most bone metastases except for an advancing lesion eroding into the right acetabulum. The patient underwent a right total hip replacement, intra-lesional curettage and cementing. After six months of sorafenib therapy, CT scanning showed enlarging liver lesions with marked elevation of serum thyroglobulin. Lenvatinib was commenced and sorafenib was ceased. He now has stable disease with a falling thyroglobulin more than 5 years after metastatic radioiodine-refractory DTC was diagnosed. In DTC, 5% of distant metastases become radioiodine-refractory, resulting in a median overall survival of 2.5–3.5 years. Tyrosine kinase inhibitor (TKI therapy has recently been demonstrated to increase progression-free survival in these patients but poses some unique management issues and is best used as part of an integrated approach with directed therapy.

    A cDNA microarray allows biologists to examine the expression of thousands of genes simultaneously. Researchers may analyze the complete transcriptional program of an organism in response to specific physiological or developmental conditions. By design, a cDNA microarray is an experiment with many variables and few controls. One question that inevitably arises when working with a cDNA microarray is data reproducibility. How easy is it to confirm mRNA expression patterns? In this paper, a case study involving the treatment of a murine macrophage RAW 264.7 cell line with tumor necrosis factor alpha (TNF) was used to obtain a rough estimate of data reproducibility. Two trials were examined and a list of genes displaying either a > 2-fold or > 4-fold increase in gene expression was compiled. Variations in signal mean ratios between the two slides were observed. We can assume that erring in reproducibility may be compensated by greater inductive levels of similar genes. Steps taken to obtain results included serum starvation of cells before treatment, tests of mRNA for quality/consistency, and data normalization.

    The SIGMA concept, under development by Argentina, represents the evolution of the Uranium Enrichment Gaseous Diffusion technology, updated to face the challenge of the new economic-based and competitive world frame. The Enrichment technology has been historically considered as a highly proliferating activity in the nuclear field, and central countries have limited the access of the developing countries to this technology. The SIGMA concept incorporates innovative proliferation resistant criteria at the beginning of the design process, and inherits all the non-proliferation features of the Gaseous Diffusion Plants (GDPs). The radical new proliferation resistant approach of the SIGMA technology, suggest a new kind of global control of the Uranium Enrichment Market, were some developing countries might access to an Enrichment plant without accessing to the technology itself. In this paper, we analyse the economy of the SIGMA plants, and the implications of this technology on the Uranium Global Market. (authors)

    Traditional gene mapping using forward genetic approaches is conducted primarily through construction of a genetic linkage map, the process of which is tedious and time-consuming, and often results in low accuracy of mapping and large mapping intervals. With the rapid development of high-throughput sequencing technology and decreasing cost of sequencing, a variety of simple and quick methods of gene mapping through sequencing have been developed, including direct sequencing of the mutant genome, sequencing of selective mutant DNA pooling, genetic map construction through sequencing of individuals in population, as well as sequencing of transcriptome and partial genome. These methods can be used to identify mutations at the nucleotide level and has been applied in complex genetic background. Recent reports have shown that sequencing mapping could be even done without the reference of genome sequence, hybridization, and genetic linkage information, which made it possible to perform forward genetic study in many non-model species. In this review, we summarized these new technologies and their application in gene mapping.

    Everyday technologies (ETs) like microwave ovens and automatic telephone services as well as assistive technologies (ATs) are often used in the performance of everyday activities. As a consequence, the ability to manage technology is important. This pilot study aimed to clarify the applicability of a model for knowledge translation to support healthcare professionals, to support technology use among older adults with dementia and their significant others. An additional aim was to explore the process of translating the model into practice. The applicability of the model (comprising a one-day course, including introduction and provision of tools, followed by interviews during and after a period of practice) was clarified for 11 healthcare professionals using a constant comparative approach. The content of the model gave the participants an eye-opening experience of technology use among persons with dementia. They also described how they had incorporated the model as a new way of thinking which supported and inspired new investigations and collaborations with colleagues and significant others. This study provided an applicable model of how research knowledge about technology use can be translated into clinical practice and be used by healthcare professionals to support the use of technology for persons with dementia.

    2009-04-01

    Patients presenting with recurrent orogenital ulcers may have complex aphthosis, Behçet\\'s disease, secondary complex aphthosis (e.g. Reiter\\'s syndrome, Crohn\\'s disease, cyclical neutropenia) or non-aphthous disease (including bullous disorders, erythema multiforme, erosive lichen planus). Behçet\\'s syndrome is a multi-system vasculitis of unknown aetiology for which there is no diagnostic test. Diagnosis is based on agreed clinical criteria that require recurrent oral ulcers and two of the following: recurrent genital ulcers, ocular inflammation, defined skin lesions and pathergy. The condition can present with a variety of symptoms, hence a high index of suspicion is necessary. The most common presentation is with recurrent mouth ulcers, often with genital ulcers; however, it may take some years before diagnostic criteria are met. All patients with idiopathic orogenital ulcers should be kept under review, with periodic focused assessment to detect evolution into Behçet\\'s disease. There is often a delay of several years between patients fulfilling diagnostic criteria and a diagnosis being made, which may contribute to the morbidity of this condition. Despite considerable research effort, the aetiology and pathogenesis of this condition remains enigmatic.

    Burns, W. C. G.

    2016-12-01

    The new Paris Agreement under the United Nations Framework Convention on Climate Change contemplates that its prospective Parties will balance emissions and sinks by 2050 as a means to effectuate the goal of holding temperature increases to well below 2°C from pre-industrial levels, as well as the more aspirational goal of holding temperature increases to 1.5°C. Most of the IPCC's AR5 scenarios that achieve these objectives contemplate the large-scale deployment of so-called "negative emissions technologies," with an emphasis on bioenergy and carbon capture and storage (BECCS), and to a lesser degree afforestation. BECCS could assuredly help society avoid passing critical climatic thresholds, or address overshoot scenarios in this century and beyond. However, it could also profound implications for food production, the status of forests, access to lands for livelihoods by vulnerable populations, and the integrity of critical ecosystems. This, in turn could have serious ramifications for human rights of some of the world's most vulnerable populations, including the rights to food, water, livelihoods and the benefits of biodiversity. The Preamble to the Paris Agreement acknowledges the need to take into consideration the potential impact of responses to climate change, providing that "Parties should, when taking action to address climate change, respect, promote and consider their respective obligations on human rights." This presentation will outline how application of a human rights-based approach to assessing such options could help to reconcile the objectives of ameliorating potential climatic impacts while protecting the human rights of potentially affected individuals and groups. This will include the potential role of Human Rights Impacts Assessments and potential configuration of HRIAs at the national and international level. It will also briefly suggest how to operationalize this approach within the Paris Agreement framework, including institutional

  12. Integrating renewable energy technologies in the electric supply industry: A risk management approach

    Energy Technology Data Exchange (ETDEWEB)

    Hoff, T.E. [Pacific Energy Group, Walnut Creek, CA (United States)

    1997-07-01

    Regulatory and technical forces are causing electric utilities to move from a natural monopoly to a more competitive environment. Associated with this movement is an increasing concern about how to manage the risks associated with the electric supply business. One approach to managing risks is to purchase financial instruments such as options and futures contracts. Another approach is to own physical assets that have low risk attributes or characteristics. This research evaluates how investments in renewable energy technologies can mitigate risks in the electric supply industry. It identifies risks that are known to be of concern to utilities and other power producers. These risks include uncertainty in fuel prices, demand, environmental regulations, capital cost, supply, and market structure. The research then determines how investments in renewables can mitigate these risks. Methods are developed to calculate the value of renewables in terms of their attributes of fuel costs, environmental costs, lead-time, modularity, availability, initial capital costs, and investment reversibility. Examples illustrate how to apply the methods.

    Transferring processes between different scales and types of mixers is a common operation in industry. Challenges within this operation include the existence of considerable differences in blending conditions between mixer scales and types. Obtaining the correct blending conditions is crucial for the ability to break up agglomerates in order to achieve the desired blend uniformity. Agglomerate break up is often an abrasion process. In this study, the abrasion rate potential of agglomerates is described by the Stokes abrasion (St(Abr)) number of the system. The St(Abr) number equals the ratio between the kinetic energy density of the moving powder bed and the work of fracture of the agglomerate. In this study, the St(Abr) approach demonstrates to be a useful tool to predict the abrasion of agglomerates during blending when technology is transferred between mixer scales/types. Applying the St(Abr) approach revealed a transition point between parameters that determined agglomerate abrasion. This study gave evidence that (1) below this transition point, agglomerate abrasion is determined by a combination of impeller effects and by the kinetic energy density of the powder blend, whereas (2) above this transition point, agglomerate abrasion is mainly determined by the kinetic energy density of the powder blend.

    1997-01-01

    The world's largest environmental cleanup effort is focused upon the DOE weapons complex. These cleanup efforts parallel those which will be required as the commercial nuclear industry reaches the end of licensed life. The Strategic Alliance for Environmental Restoration (Strategic Alliance), reflects the cooperative interest of industry, commercial nuclear utilities, university and national laboratory team members to bring a collaborative best-in-class approach to finding, and providing effective delivery of innovative environmental remediation technologies to the DOE Complex and subsequently to industry. The collaborative team of the Strategic Alliance includes ComEd, Duke Engineering and Services, 3M, ICF Kaiser, Florida International University, Argonne National Laboratory in concert with DOE. The Strategic Alliance approach to technology qualification and deployment provides DOE, through a Cooperative Agreement, with a new way of bringing industry principles to technology research and developed activities. This paper will describe the approach and activities the Strategic Alliance is taking to provide cost effective technology solutions to DOE/Industry needs for decontamination and decommissioning needs

    Full Text Available The Cox maze procedure developed originally in 1987 by Dr James Cox has evolved from a “cut and sew” surgical procedure, where the maze was applied using multiple surgical cuts, to an extensive use of surgical ablation technology where ablation lesions are placed with alternative energy sources (radiofrequency, cryothermy, microwave, and high-frequency ultrasound. Furthermore, the procedure has changed from a median sternotomy approach only to one that can be performed minimally invasively and robotically. The purpose of this paper is to review the current available technology for the ablation of atrial fibrillation as well as the different procedural approaches for the surgical ablation of atrial fibrillation.

    New orthopaedic technology is constantly being developed to help improve patient care. New technology may lead to a waste of resources or lead to harm for the patient if it is not properly evaluated before it is accepted as a standard of care. The purpose of this article is to assess how new technology can be implemented safely while maintaining an environment that allows for surgical innovation through an evidence-based approach. Although randomized controlled trials (Level-I evidence) are typically seen as the so-called gold standard with regard to treatment efficacy, randomized trials may not be the most effective form of evaluating a new technology. In many circumstances, a prospective cohort series or large registry that documents outcomes and adverse events may be more effective and practical for the evaluation of a new surgical technology.

  18. Comparison of approaches to Total Quality Management. Including an examination of the Department of Energy`s position on quality management

    Energy Technology Data Exchange (ETDEWEB)

    Bennett, C.T.

    1994-03-01

    This paper presents a comparison of several qualitatively different approaches to Total Quality Management (TQM). The continuum ranges from management approaches that are primarily standards -- with specific guidelines, but few theoretical concepts -- to approaches that are primarily philosophical, with few specific guidelines. The approaches to TQM discussed in this paper include the International Organization for Standardization (ISO) 9000 Standard, the Malcolm Baldrige National Quality Award, Senge`s the Learning Organization, Watkins and Marsick`s approach to organizational learning, Covey`s Seven Habits of Highly Successful People, and Deming`s Fourteen Points for Management. Some of these approaches (Deming and ISO 9000) are then compared to the DOE`s official position on quality management and conduct of operations (DOE Orders 5700.6C and 5480.19). Using a tabular format, it is shown that while 5700.6C (Quality Assurance) maps well to many of the current approaches to TQM, DOE`s principle guide to management Order 5419.80 (Conduct of Operations) has many significant conflicts with some of the modern approaches to continuous quality improvement.

    The research aimed to enhance Grade 10 Thai students' scientific argumentation in learning about electric field through science, technology, and society (STS) approach. The participants included 45 Grade 10 students who were studying in a school in Nongsonghong, Khon Kaen, Thailand. Methodology regarded interpretive paradigm. The intervention was the force unit which was provided based on Yuenyong (2006) STS approach. Students learned about the STS electric field unit for 4 weeks. The students' scientific argumentation was interpreted based on Toulmin's argument pattern or TAP. The TAP provided six components of argumentation including data, claim, warrants, qualifiers, rebuttals and backing. Tools of interpretation included students' activity sheets, conversation, journal writing, classroom observation and interview. The findings revealed that students held the different pattern of argumentation. Then, they change pattern of argumentation close to the TAP. It indicates that the intervention of STS electric field unit enhance students to develop scientific argumentation. This finding may has implication of further enhancing scientific argumentation in Thailand.

    2016-11-01

    Full Text Available There is a large body of research on technology-enhanced learning, but questions related to the educational effectiveness of technology use still needs to be questioned. In this paper, I argue that digital innovators’ stories about technology enhancement may constitute a rich source for understanding this complex educational phenomenon both in relation to teachers’ daily practices and the implementation of ICT in higher education at large. Based on biographical interviews with “digital innovators”, the aim of this paper is to investigate how [their] digital competence is used to enhance teaching and learning in higher education. This paper asks; how do digital innovators approach the use of ICT to enhance students’ learning and what are the organisational conditions for this approach? The findings suggests that technology-enhancement is linked to nine key characteristics: different educational models, authenticity, pedagogical added values, meaningful student activities, changing approaches to feedback, assessment and connection with the outside world, as well as holistic planning, supportive leaders and strong micro-cultures. This paper proposes a more nuanced understanding of the term technology enhanced learning and suggests strategies for educational development and further investigations related to this phenomenon in higher education.

  2. Applicable approach of the wireless technology for Korean nuclear power plants

    Ko, Do Young; Lee, Soo Ill

    2013-01-01

    Highlights: • To apply wireless technology for Korean NPPs, several stipulations are proposed. • WLAN is proposed as the most appropriate wireless technology for Korean NPPs. • WLAN can be applied to the specific fields except in the control system. • An attitude survey on wireless showed that 94.7% agree with the necessity of wireless. - Abstract: Recently, many nuclear power plants (NPPs) over the world use various types of wireless systems for the advantages. Unfortunately, wireless technologies are not currently installed in any Korean NPPs because it is difficult to solve the negative impact of unexpected outcomes or failures from the influence of the wireless technologies, which is electromagnetic interference and radio-frequency interference (EMI/RFI). Moreover, a lack of desire on the part of Korean nuclear industry to implement it leads to give up benefit from the wireless technologies. To install the wireless technologies with maximum benefit and minimum risk, a systematic approach, which quantify the negative impact and prevent the influence, is essential; therefore, this paper describes an applicable research result on the wireless technology for Korean NPPs based on regulatory guides and current wireless hardware and software technologies. Also, survey on the needs for the wireless technology for Korean nuclear power plants was conducted, because the level of awareness of workers in NPPs regarding wireless technologies is very important issue. In this paper, we propose an applicable system to enhance the applicability for the wireless technology for Korean NPPs. The result based on proposed applicable system shows that wireless local area network (WLAN) is the representative candidate for Korean NPPs, which can be applied to the specific fields of radiation monitoring, voice and data communication, component monitoring and instrumentation, and wireless cameras

    2011-07-01

    Despite a growing consensus that ethical and social values should be addressed in health technology assessment (HTA) processes, there exist a variety of methods for doing so. There is growing interest in involving citizens in policy development to ensure that decisions are legitimate, and reflect the broad social values of the public. We sought to bring these issues together by employing a participatory approach to elicit ethical and social values in HTA. Our primary objective was to elicit a set of ethical and social values from citizens that could be used to guide Ontario's HTA evidentiary review and appraisal process. A secondary objective was to explore the feasibility of using participatory approaches to elicit these values. A 14-person Citizens' Reference Panel on Health Technologies was established to provide input to the Ontario Health Technology Advisory Committee in developing its recommendations. A mixed methods approach was used where informed, deliberative discussions were combined with pre- and post-questionnaires, which assessed the relative importance of various ethical and social values as well as their stability over time. Over the course of five meetings, panel members progressed toward the identification of a set of core values -universal access, choice and quality care. These values were consistently prioritized as the core values that should be considered in the evaluation of health technologies and ensuing recommendations. Sustained and deliberative methods, like a citizens' panel, offer a promising approach for eliciting ethical and social values into HTA. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Full Text Available In Romania, Dornfelder is a rare grape variety which started to become popular among some wine producers due to the intense colour of its wines. However, it is mostly used in blends and therefore varietal wines of Dornfelder are not found too often. In this paper we present some technological approaches suitable for the production of varietal wines of Dornfelder, some of them novel for the Romanian wine industry. The experimental samples include a classical red wine made by the usual technol- ogy using freshly harvested grapes (DW = Dornfelder wine and two variants made with dried grapes (DR and DWDR. The DR variant (Dornfelder raisin wine is produced by a straw-wine type technology, by fermenting a must obtained from grapes dried for 7 weeks. The DWDR is a variant obtained by fermenting a mixture of crushed dried grapes and new Dornfelder wine, the ratio of crushed raisins to wine being 1:1 in weight. The wines were analysed both physico-chemically and sensorially. After one year of aging in bottles, the variant DWDR of wine, produced by fermenting dried berries in already finished wine, proved to be the most balanced in taste, with an intense and complex aroma of berries and red fruit, also displaying good aging potential and stability. The variant DR appeared dense and intense, but with a less complex fruity aroma, with a dominant note of blueberries and black currants. Both straw wines are preferable to the classic varietal wine, which is vinous, but lacks structure and displays a dissociated acidity and a simple aromatic profile, with dominant sour cherry, mineral and vegetal notes.

    Green chemical engineering recognises the concept of developing innovative environmentally benign technologies to protect human health and ecosystems. In order to explore this concept for minimizing industrial waste and for reducing the environmental impact of hazardous chemicals, new greener approaches need to be adopted for the extraction of heavy metals from industrial waste. In this review, a range of conventional processes and new green approaches employed for metal extraction are discussed in brief. Chelation technology, a modern research trend, has shown its potential to develop sustainable technology for metal extraction from various metal-contaminated sites. However, the interaction mechanism of ligands with metals and the ecotoxicological risk associated with the increased bioavailability of heavy metals due to the formation of metal-chelant complexes is still not sufficiently explicated in the literature. Therefore, a need was felt to provide a comprehensive state-of-the-art review of all aspects associated with chelation technology to promote this process as a green chemical engineering approach. This article elucidates the mechanism and thermodynamics associated with metal-ligand complexation in order to have a better understanding of the metal extraction process. The effects of various process parameters on the formation and stability of complexes have been elaborately discussed with respect to optimizing the chelation efficiency. The non-biodegradable attribute of ligands is another important aspect which is currently of concern. Therefore, biotechnological approaches and computational tools have been assessed in this review to illustrate the possibility of ligand degradation, which will help the readers to look for new environmentally safe mobilizing agents. In addition, emerging trends and opportunities in the field of chelation technology have been summarized and the diverse applicability of chelation technology in metal extraction from

    Rayner, S.; Cantor, R.

    1987-01-01

    This paper consists of an argument and a pilot study. First is a general, perhaps philosophical, argument against the National Academy's viewpoint that dealing with risk is a two-stage process consisting of (a) assessment of facts, and (b) evaluation of facts in sociopolitical context. They argue that societal risk intrinsically revolves around social relations as much as around evaluations of probability. Second, they outline one particular approach to analyzing societal risk management styles. They call this the fairness hypothesis. Rather than focusing on probabilities and magnitudes of undesired events, this approach emphasizes societal preferences for principles of achieving consent to a technology, distributing liabilities, and investing trust in institutions. Conflict rather than probability is the chief focus of this approach to societal risk management. This view is illustrated by a recent empirical pilot study that explored the fairness hypothesis in the context of new nuclear technologies

    The operation of VTOL aircraft in the city-center environment will require complex landing-approach trajectories that insure adequate clearance from other traffic and obstructions and provide the most direct routing for efficient operations. As part of a larger program to develop the necessary technology base, a flight investigation was undertaken to study the problems associated with manual and automatic control of steep, decelerating instrument approaches and landings. The study employed a three-cue flight director driven by control laws developed and refined during manual-control studies and subsequently applied to the automatic approach problem. The validity of this approach was demonstrated by performing the first automatic approach and landings to a predetermined spot ever accomplished with a helicopter. The manual-control studies resulted in the development of a constant-attitude deceleration profile and a low-noise navigation system.

  19. Proposal for a technology-neutral safety approach for new reactor designs

    International Nuclear Information System (INIS)

    2007-09-01

    Many states are considering an expansion of their nuclear power generation programmes. Many of the technologies and concepts are new and innovative. The current design and licensing rules are applicable to mostly large water reactors and there are no accepted rules in place for design, safety assessment and licensing for new innovative nuclear power plants. This TECDOC proposes a (new) safety approach and a methodology to generate technology-neutral (i.e. independent of reactor technology) safety requirements and a 'safe design' for advanced and innovative reactors. The experience gained in decades of design and licensing, combined with the development of risk-based concepts, has provided insights that will form the basis for new safety rules and requirements. Many lessons learned acknowledge the importance of such concepts as safety goals and defence in depth and the benefits of integrating risk insights early in an iterative design process. A new safety approach will incorporate many of the new developments in these concepts. For example, the probabilistic elements of defence in depth will help define the cumulative provisions to compensate for uncertainty and incompleteness of our knowledge of accident initiation and progression. This TECDOC also identifies areas of work, which will require further definition, research and development and guidance on application. This publication is to be used as a guide to developing a new technology-neutral safety approach, and as a guide in the application of methodologies to define the safety requirements for an innovative reactor designs. The method proposes an integration of deterministic and probabilistic considerations with established principles and concepts such as safety goals and defence in depth. The TECDOC recommends that the structure of the new technology-neutral main pillars for the design and licensing of innovative nuclear reactors be developed following a top-down approach to reflect a newer risk-informed and

    As it is more environmentally sound and friendly than conventional energy technologies that emit carbon dioxide, hydrogen technology can play a key role in solving the problems caused by the greenhouse gas effect and in coping with the hydrogen economy. Numerous countries around the world, including Korea, have increasingly focused on R and D where hydrogen technology development is concerned. This paper focuses on the use of the fuzzy analytic hierarchy process (fuzzy AHP), which is an extension of the AHP method and uses interval values to reflect the vagueness of human thought, to assess national competitiveness in the hydrogen technology sector. This analysis based on the AHP and fuzzy AHP methods revealed that Korea ranked 6th in terms of national competitiveness in the hydrogen technology sector. (author)

    Full Text Available Neurological diseases causing motor/cognitive impairments are among the most common causes of adult-onset disability. More than one billion of people are affected worldwide, and this number is expected to increase in upcoming years, because of the rapidly aging population. The frequent lack of complete recovery makes it desirable to develop novel neurorehabilitative treatments, suited to the patients, and better targeting the specific disability. To date, rehabilitation therapy can be aided by the technological support of robotic-based therapy, non-invasive brain stimulation, and neural interfaces. In this perspective, we will review the above methods by referring to the most recent advances in each field. Then, we propose and discuss current and future approaches based on the combination of the above. As pointed out in the recent literature, by combining traditional rehabilitation techniques with neuromodulation, biofeedback recordings and/or novel robotic and wearable assistive devices, several studies have proven it is possible to sensibly improve the amount of recovery with respect to traditional treatments. We will then discuss the possible applied research directions to maximize the outcome of a neurorehabilitation therapy, which should include the personalization of the therapy based on patient and clinician needs and preferences.

    2014-01-01

    The volatility and uncertainty in the process of technological developments are growing faster than ever due to rapid technological innovations. Such phenomena result in integration among disparate technology fields. At this point, it is a critical research issue to understand the different roles and the propensity of each element technology for technological convergence. In particular, the network-based approach provides a holistic view in terms of technological linkage structures. Furthermore, the development of new indicators based on network visualization can reveal the dynamic patterns among disparate technologies in the process of technological convergence and provide insights for future technological developments. This research attempts to analyze and discover the patterns of the international patent classification codes of the United States Patent and Trademark Office's patent data in printed electronics, which is a representative technology in the technological convergence process. To this end, we apply the physical idea as a new methodological approach to interpret technological convergence. More specifically, the concepts of entropy and gravity are applied to measure the activities among patent citations and the binding forces among heterogeneous technologies during technological convergence. By applying the entropy and gravity indexes, we could distinguish the characteristic role of each technology in printed electronics. At the technological convergence stage, each technology exhibits idiosyncratic dynamics which tend to decrease technological differences and heterogeneity. Furthermore, through nonlinear regression analysis, we have found the decreasing patterns of disparity over a given total period in the evolution of technological convergence. This research has discovered the specific role of each element technology field and has consequently identified the co-evolutionary patterns of technological convergence. These new findings on the evolutionary

    This paper discusss the systems approach taken by NASA and the Jet Propulsion Laboratory in the commercialization of land-mobile satellite services (LMSS) in the United States. As the lead center for NASA's Mobile Satellite Program, JPL was involved in identifying and addressing many of the key barriers to commercialization of mobile satellite communications, including technical, economic, regulatory and institutional risks, or uncertainties. The systems engineering approach described here was used to mitigate these risks. The result was the development and implementation of the JPL Mobile Satellite Experiment Project. This Project included not only technology development, but also studies to support NASA in the definition of the regulatory, market, and investment environments within which LMSS would evolve and eventually operate, as well as initiatives to mitigate their associated commercialization risks. The end result of these government-led endeavors was the acceleration of the introduction of commercial mobile satellite services, both nationally and internationally.

  6. New Approaches and New Technologies for the Verification of Nuclear Disarmament

    2013-01-01

    ESARDA’s New Approaches/Novel Technologies Working group has recently begun to take a great interest in technology for use in arms control verification, in parallel with a focus on Nuclear Safeguards technology. A topic-based meeting of members of the NA/NT Subgroup was hosted at Joint Research Centre (JRC), ITU-Nuclear Security Unit in Ispra (Italy), to further explore the technical issues and opportunities presented by the need for new approaches and technologies in a future verified nuclear weapons dismantlement regime. Nuclear warheads must contain radioactive material and, by their nature, gamma rays and neutrons are likely to penetrate to the outside of the warhead casing and even metal containers. Therefore radiation signatures should be detectable by appropriate pieces of equipment. For this reason, researchers in the field of technical verification of nuclear warhead dismantlement have studied and developed technologies for Non-Destructive Assay (NDA). This paper presents a generic dismantlement pathway for verified nuclear warhead dismantlement, based on the scenario employed by the UK-Norway initiative for their exercise in 2008/9. Using this as a framework the types of measurement challenge likely to be presented to a verifying inspector are discussed. The problem of intrusiveness of measurements in relation to the issue of proliferative release of classified information about the warhead attributes is discussed and the concept of ‘information barriers is introduced as a possible solution to this issue. A list of candidate technologies for use in verification activities, with or without information barriers is then presented and, since most of these are new or novel approaches to the issue, an already-established system for classifying them – in terms of state of development and complexity of use in this context – is proposed. Finally, the concept of capturing this information as a library of ‘data sheets’, designed for periodic review as

    Jones, Michael; Mueller, James; Morris, John

    2017-01-01

    This article describes a flexible and effective approach to research and development in an era of rapid technological advancement. The approach relies on secondary dispersal of grant funds to commercial developers through a competitive selection process. This "App Factory" model balances the practical reliance on multi-year funding needed to sustain a rehabilitation engineering research center (RERC), with the need for agility and adaptability of development efforts undertaken in a rapidly changing technology environment. This approach also allows us to take advantage of technical expertise needed to accomplish a particular development task, and provides incentives to deliver successful products in a cost-effective manner. In this article, we describe the App Factory structure, process, and results achieved to date; and we discuss the lessons learned and the potential relevance of this approach for other grant-funded research and development efforts. Data presented on the direct costs and number of downloads of the 16 app development projects funded in the App Factory's first 3 years show that it can be an effective means for supporting focused, short-term assistive technology development projects.

    Shai, Yair; Ingman, D.; Suhir, E.

    Species” of military aircraft, commercial aircraft and private cars have been chosen in our analysis as illustrations of the fruitfulness of the “ holistic” approach. The obtained data show that both commercial “ species” exhibit similar “ survival dynamics” in compare with those of the military species of aircraft: lifetime distributions were found to be Weibull distributions for all “ species” however for commercial vehicles, the shape parameters were a little higher than 2, and scale parameters were 19.8 years (aircraft) and 21.7 (cars) whereas for military aircraft, the shape parameters were much higher and the mean time to failure much longer. The difference between the lifetime characteristics of the “ species” can be attributed to the differences in the social, operational, economic and safety-and-reliability requirements and constraints. The obtained information can be used to make tentative predictions for the most likely trends in the given field of vehicular technology. The following major conclusions can be drawn from our analysis: 1) The suggested concept based on the use of HLPFs reflects the current state and the general perceptions in the given field of engineering, including aerospace technologies, and allows for all the inherent and induced factors to be taken into account: any type of failures, usage profiles, economic factors, environmental conditions, etc. The concept requires only very general input data for the entire population. There is no need for the less available information about individual articles. 2) Failure modes are not restricted to the physical type of failures and include economic, cultural or social effects. All possible causes, which might lead to making a decision to terminate the use of a particular type

    Highlights: • Dynamic programming method is used in transportation fuel portfolio planning. • The learning effect in new fuel technology is endogenously modeled through an experience curve. • Cellulosic biofuels play critical role in de-carbonization transport sector in near term. • The initial 3–4 billion gallons production is critical to bring down cellulosic biofuels’ cost. • Large penetration of Zero Emission Vehicles will discourage development of cellulosic biofuels. - Abstract: Promoting the adoption of low-carbon technologies in the transportation fuel portfolio is an effective strategy to mitigate greenhouse gas emissions from the transportation sector worldwide. However, as one of the most promising low-carbon fuels, cellulosic biofuel has not fully entered commercial production. Governments could provide guidance in developing cellulosic biofuel technologies, but no systematic approach has been proposed yet. We establish a dynamic programming framework for investigating time-dependent and adaptive decision-making processes to develop advanced fuel technologies. The learning-by-doing effect inherited in the technology development process is included in the framework. The proposed framework is applied in a case study to explore the most economical pathway for California to develop a solid cellulosic biofuel industry under its Low Carbon Fuel Standard. Our results show that cellulosic biofuel technology is playing a critical role in guaranteeing California’s 10% greenhouse gas emission reduction by 2020. Three to four billion gallons of cumulative production are needed to ensure that cellulosic biofuel is cost-competitive with petroleum-based fuels or conventional biofuels. Zero emission vehicle promoting policies will discourage the development of cellulosic biofuel. The proposed framework, with small adjustments, can also be applied to study new technology development in other energy sectors.

    The growth in urbanization and industrial activities has caused solid waste management problems. As a solution the integrated approach has been chosen to manage the solid waste. Developing and implementing integrated solid waste management involve combined technologies and alternatives which are suitable with local laws condition. This research showed that Analytical Hierarchy Process (AHP) has the potential as a decision making tool that can be used in selecting process of solid waste management technology. Three levels hierarchy was developed with the goal at the top level, followed by criteria and alternatives. By using this technique, the priority of each considered technology will be determined where technology with the highest priority is more suitable to be developed. Sensitivity analysis was carried out to test the sensitivity of final decision towards inconsistency of judgement. Application of AHP to determine priority in selecting solid waste management technology was explained in this research based on a case study in the Port Dickson Municipal Council. Analysis of result showed that the combination of recycling technology and composting are suitable to be applied in the Port Dickson district. (author)

    The proper allocation of the limited R and D resources under the restructuring of the electric industry is a primary motivator for this electricity technology roadmap (eTRM) initiative. Because the major interests of CEOs could be the short term profit of their company under the competitive electric industry, it would wrong of them to cut back on the long term R and D budgets which make it impossible to develop all the technologies. Therefore, we should select and support only the favorable and competitive technologies to meet the future market needs using the TRM approach with the concept of ''selection and concentration.'' This study aims at defining the key technologies basis from the forecasts of what is possible or likely to happen in the future and planning the course of action for the technology development in the electricity field in Korea. The selected technologies could be the candidates for the mid and long term R and D program supported concentrically by the Electricity Industry Infrastructure Fund. (orig.)

    Yang, Xiaoliang

    Is a global research partnership effective in developing, deploying, and diffusing clean energy technologies? Drawing on and extending innovation system studies, this doctoral dissertation elaborates an analytical model for a global technology learning system; examines the rationales, mechanisms, and effectiveness of the United States-- China Clean Energy Research Center Advanced Coal Technology Consortium (CERC-ACTC); and analyzes government's role in developing and implementing carbon capture and storage technologies in the United States (U.S.) and China. Studies have shown that successful technology innovation leads to economic prosperity and national competence, and prove that technology innovation does not happen in isolation but rather within interactive systems among stakeholders. However, the innovation process itself remains unclear, particularly with regard to interactive learning among and between major institutional actors, including technology developers, regulators, and financial organizations. This study seeks to advance scholarship on the interactive learning from the angle of global interactive learning. This dissertation research project seeks, as well, to inform policy-makers of how to strengthen international collaboration in clean energy technology development. The U.S.--China CERC-ACTC announced by Presidents Obama and Hu in 2009, provided a unique opportunity to close this scholarly gap. ACTC aimed to "advance the coal technology needed to safely, effectively, and efficiently utilize coal resources including the ability to capture, store, and utilize the emissions from coal use in both nations " through the joint research and development by U.S. and Chinese scientists and engineers. This dissertation project included one-year field research in the two countries, with in-depth interviews of key stakeholders, a survey of Consortium participants, analysis of available data, and site visits to collaborative research projects from 2013-2014.

    Policy simulations in environmental-economic models are influenced by the modelling of technological change. However, environmental-economic models have generally treated technological change as exogenous. This paper presented simulations with a new modelling approach in which technological change was portrayed and linked to actual production processes in 3 industry sectors in Germany, namely iron and steel; cement; and, pulp and paper. Technological choice was modelled via investments in new production process lines. The generic modelling procedure for all 3 industry sectors was presented along with an overview of the relevant sector-specific modelling results and the integration into the macro-economic model PANTA RHEI. The new modelling approach endogenizes technological change. As such, it considers that policy interventions may affect the rate and direction of technological progress. Carbon tax simulations were also performed to investigate the influence of a tax in both the new and conventional modelling approach. For the energy- and capital-intensive industries considered in this study, the conventional top-down approach overestimated the short-term possibilities to adapt to higher carbon dioxide (CO 2 ) prices in the early years. Since the new approach includes policy-induced technological change and process shifts, it also captures the long-term effects on CO 2 emissions far beyond the initial price impulse. It was concluded that the new modelling approach results in significantly higher emission reductions than the conventional approach. Therefore, the estimated costs of the climate policy are lower using the new modelling approach. 37 refs., 2 tabs., 4 figs., 1 appendix

  17. Industry-Cost-Curve Approach for Modeling the Environmental Impact of Introducing New Technologies in Life Cycle Assessment.

    The environmental costs and benefits of introducing a new technology depend not only on the technology itself, but also on the responses of the market where substitution or displacement of competing technologies may occur. An internationally accepted method taking both technological and market-mediated effects into account, however, is still lacking in life cycle assessment (LCA). For the introduction of a new technology, we here present a new approach for modeling the environmental impacts within the framework of LCA. Our approach is motivated by consequential life cycle assessment (CLCA) and aims to contribute to the discussion on how to operationalize consequential thinking in LCA practice. In our approach, we focus on new technologies producing homogeneous products such as chemicals or raw materials. We employ the industry cost-curve (ICC) for modeling market-mediated effects. Thereby, we can determine substitution effects at a level of granularity sufficient to distinguish between competing technologies. In our approach, a new technology alters the ICC potentially replacing the highest-cost producer(s). The technologies that remain competitive after the new technology's introduction determine the new environmental impact profile of the product. We apply our approach in a case study on a new technology for chlor-alkali electrolysis to be introduced in Germany.

  18. Tracing Technological Development Trajectories: A Genetic Knowledge Persistence-Based Main Path Approach.

    Directory of Open Access Journals (Sweden)

    Hyunseok Park

    Full Text Available The aim of this paper is to propose a new method to identify main paths in a technological domain using patent citations. Previous approaches for using main path analysis have greatly improved our understanding of actual technological trajectories but nonetheless have some limitations. They have high potential to miss some dominant patents from the identified main paths; nonetheless, the high network complexity of their main paths makes qualitative tracing of trajectories problematic. The proposed method searches backward and forward paths from the high-persistence patents which are identified based on a standard genetic knowledge persistence algorithm. We tested the new method by applying it to the desalination and the solar photovoltaic domains and compared the results to output from the same domains using a prior method. The empirical results show that the proposed method can dramatically reduce network complexity without missing any dominantly important patents. The main paths identified by our approach for two test cases are almost 10x less complex than the main paths identified by the existing approach. The proposed approach identifies all dominantly important patents on the main paths, but the main paths identified by the existing approach miss about 20% of dominantly important patents.

    Society typically relies on the industrial sector to supply product and service innovations through the free market system. In some areas of free market failure deemed important to society - such as Assistive Technology - governments intervene by applying alternative innovation systems. This paper contends that governments consistently and inappropriately support an exploratory grant approach led by academia which generates knowledge in conceptual and prototype states, and instead should shift to a procurement contract approach led by industry which designs, tests and deploys commercial products and services.

    If commercialization of new technologies is the primary objective of the Department of Energy's Research, Development and Demonstration (RD and D) programs, the ultimate measure of benefit from RD and D programs is the extent of commercial acceptance of the developed technologies. Uncertainty about barriers to commercialization - government policy, fuel supply, etc. - make the task of estimating this acceptance very difficult. However, given that decisions must be made regarding allocation of RD and D funds, the best information available, with due regard for uncertainty, should serve as input to these decisions. An approach is presented for quantifying the range of market potential for new technologies (specifically in the utility sector) based on historical information and known plans for the future.

    As the demographics of many countries shift towards an ageing population it is predicted that the prevalence of diseases affecting cognitive capabilities will continually increase. One approach to enabling individuals with cognitive decline to remain in their own homes is through the use of cognitive prosthetics such as reminding technology. However, the benefit of such technologies is intuitively predicated upon their successful adoption and subsequent use. Within this paper we present a knowledge-based feature set which may be utilized to predict technology adoption amongst Persons with Dementia (PwD). The chosen feature set is readily obtainable during a clinical visit, is based upon real data and grounded in established research. We present results demonstrating 86% accuracy in successfully predicting adopters/non-adopters amongst PwD.

    Attempts to achieve widespread use of software verification tools have been notably unsuccessful. Even 'straightforward', classic, and potentially effective verification tools such as lint-like tools face limits on their acceptance. These limits are imposed by the expertise required applying the tools and interpreting the results, the high false positive rate of many verification tools, and the need to integrate the tools into development environments. The barriers are even greater for more complex advanced technologies such as model checking. Web-hosted services for advanced verification technologies may mitigate these problems by centralizing tool expertise. The possible benefits of this approach include eliminating the need for software developer expertise in tool application and results filtering, and improving integration with other development tools.

    A simplified three-dimensional Monte Carlo simulation model of in vitro tumor growth and response to fractionated radiotherapeutic schemes is presented in this paper. The paper aims at both the optimization of radiotherapy and the provision of insight into the biological mechanisms involved in tumor development. The basics of the modeling philosophy of Duechting have been adopted and substantially extended. The main processes taken into account by the model are the transitions between the cell cycle phases, the diffusion of oxygen and glucose, and the cell survival probabilities following irradiation. Specific algorithms satisfactorily describing tumor expansion and shrinkage have been applied, whereas a novel approach to the modeling of the tumor response to irradiation has been proposed and implemented. High-performance computing systems in conjunction with Web technologies have coped with the particularly high computer memory and processing demands. A visualization system based on the MATLAB software package and the virtual-reality modeling language has been employed. Its utilization has led to a spectacular representation of both the external surface and the internal structure of the developing tumor. The simulation model has been applied to the special case of small cell lung carcinoma in vitro irradiated according to both the standard and accelerated fractionation schemes. A good qualitative agreement with laboratory experience has been observed in all cases. Accordingly, the hypothesis that advanced simulation models for the in silico testing of tumor irradiation schemes could substantially enhance the radiotherapy optimization process is further strengthened. Currently, our group is investigating extensions of the presented algorithms so that efficient descriptions of the corresponding clinical (in vivo) cases are achieved.

    Flight deck-based vision systems, such as Synthetic and Enhanced Vision System (SEVS) technologies, have the potential to provide additional margins of safety for aircrew performance and enable the implementation of operational improvements for low visibility surface, arrival, and departure operations in the terminal environment with equivalent efficiency to visual operations. To achieve this potential, research is required for effective technology development and implementation based upon human factors design and regulatory guidance. This research supports the introduction and use of Synthetic Vision Systems and Enhanced Flight Vision Systems (SVS/EFVS) as advanced cockpit vision technologies in Next Generation Air Transportation System (NextGen) operations. Twelve air transport-rated crews participated in a motion-base simulation experiment to evaluate the use of SVS/EFVS in NextGen low visibility approach and landing operations. Three monochromatic, collimated head-up display (HUD) concepts (conventional HUD, SVS HUD, and EFVS HUD) and two color head-down primary flight display (PFD) concepts (conventional PFD, SVS PFD) were evaluated in a simulated NextGen Chicago O'Hare terminal environment. Additionally, the instrument approach type (no offset, 3 degree offset, 15 degree offset) was experimentally varied to test the efficacy of the HUD concepts for offset approach operations. The data showed that touchdown landing performance were excellent regardless of SEVS concept or type of offset instrument approach being flown. Subjective assessments of mental workload and situation awareness indicated that making offset approaches in low visibility conditions with an EFVS HUD or SVS HUD may be feasible.

    Full Text Available An increasing debate is growing today, in both academic and research-in-action contexts, about the roles of new and traditional technologies in raising knowledge of agents involved, as well as in boosting an effective development of communities. The last century has been largely dominated by capital-intensive technologies, impacting large and populated areas. From the late 1990s up to the present days, due to social, financial, environmental concerns, new low-impact, local-born, little to medium-scale experiences have been challenging large technologies, with interesting results. The importance of such experiences seems to lay on the abilities and knowledge of local populations, which are quite difficult to emerge as formal methodologies and attain recognizable levels of generalization and sharing. Yet the effectiveness of local-based technologies is being increasingly documented, often succeeding in cases where more formal technologies had previously failed. The EU-funded ANTINOMOS project has largely dealt with local-community knowledge enhancing and managing in the water sector management, aiming at creating a real learning environment for the sharing and the active generation of knowledge through mutual synergies. In this paper, the above subject is discussed and carried out with a cross-disciplinary, cross-scale, multi-agent approach, considering the different forms of local knowledge and language involved.

    Full Text Available Water shortage and water pollution are important factors restricting sustainable social and economic development. As a typical coal resource-exhausted city and a node city of the South-to-North Water Transfer East Route Project in China, Zaozhuang City’s water resources management faces multiple constraints such as transformation of economic development, restriction of groundwater exploitation, and improvement of water environment. In this paper, we develop a linear optimization model by input–output analysis to study water resources management with the introduction of three advanced sewage treatment technologies for pollutant treatment and reclaimed water production. The simulation results showed that from 2014 to 2020, Zaozhuang City will realize an annual GDP growth rate of 7.1% with an annual chemical oxygen demand (COD emissions reduction rate of 5.5%. The proportion of primary industry, secondary industry, and tertiary industry would be adjusted to 5.6%, 40.8%, and 53.6%, respectively. The amount of reclaimed water supply could be increased by 91% and groundwater supply could be decreased by 6%. Based on the simulation, this model proposes a scientific reference on water resources management policies, including water environment control, water supply plan, and financial subsidy, to realize the sustainable development of economy and water resources usage.

    2013-04-01

    Through its coordinated research activities, the IAEA promotes the development and application of nuclear technologies in Member States. The scientific and technical knowledge required for the construction and operation of large nuclear fusion research facilities, including ITER and the Laser Megajoule in France, and the Z machine and the National Ignition Facility in the United States of America, necessitates several accompanying research and development programmes in physics and technology. This is particularly true in the areas of materials science and fusion technology. Hence, the long standing IAEA effort to conduct coordinated research projects (CRPs) in these areas is aimed at: (i) the development of appropriate technical tools to investigate the issue of materials damage and degradation in a fusion plasma environment; and (ii) the emergence of a knowledge based understanding of the various processes underlying materials damage and degradation, thereby leading to the identification of suitable candidate materials fulfilling the stringent requirements of a fusion environment in any next step facility. Dense magnetized plasma (DMP) devices serve as a first test bench for testing of fusion relevant plasma facing materials, diagnostic development and calibration, technologies and scaling to conceptual principles of larger devices while sophisticated testing facilities such as the International Fusion Materials Irradiation Facility (IFMIF) are being designed. The CRP on Integrated Approach to Dense Magnetized Plasmas Applications in Nuclear Fusion Technology described herein was initiated in 2007 with the participation of 12 research institutions in 8 Member States and was concluded in 2011. It was designed with specific research objectives falling into two main categories: support to mainstream fusion research and development of DMP technology. This publication is a compilation of the individual reports submitted by the 12 CRP participants. These reports discuss

    Science.gov (United States)

    Fern, Lisa Carolynn

    to improve the methodology for defining technology requirements for regulators in the future. The biggest shortcoming of the presented research program was the absence of the explicit definition, generation and analysis of potential human-automation architectures. Failure to execute this step in the research process resulted in less efficient evaluation of the candidate prototypes technologies in addition to a lack of exploration of different approaches to human-automation cooperation. Defining potential human-automation architectures a priori also allows regulators to develop scenarios that will stress the performance boundaries of the technology during the evaluation phase. The importance of adding this step of generating and evaluating candidate human-automation architectures prior to formal empirical evaluation is discussed. This document concludes with a look at both the importance of, and the challenges facing, the inclusion of examining human-automation coordination issues as part of the safety assurance activities of new technologies.

  9. Beyond nutrient-based food indices: a data mining approach to search for a quantitative holistic index reflecting the degree of food processing and including physicochemical properties.

    Processing has major impacts on both the structure and composition of food and hence on nutritional value. In particular, high consumption of ultra-processed foods (UPFs) is associated with increased risks of obesity and diabetes. Unfortunately, existing food indices only focus on food nutritional content while failing to consider either food structure or the degree of processing. The objectives of this study were thus to link non-nutrient food characteristics (texture, water activity (a w ), glycemic and satiety potentials (FF), and shelf life) to the degree of processing; search for associations between these characteristics with nutritional composition; search for a holistic quantitative technological index; and determine quantitative rules for a food to be defined as UPF using data mining. Among the 280 most widely consumed foods by the elderly in France, 139 solid/semi-solid foods were selected for textural and a w measurements, and classified according to three degrees of processing. Our results showed that minimally-processed foods were less hyperglycemic, more satiating, had better nutrient profile, higher a w , shorter shelf life, lower maximum stress, and higher energy at break than UPFs. Based on 72 food variables, multivariate analyses differentiated foods according to their degree of processing. Then technological indices including food nutritional composition, a w , FF and textural parameters were tested against technological groups. Finally, a LIM score (nutrients to limit) ≥8 per 100 kcal and a number of ingredients/additives >4 are relevant, but not sufficient, rules to define UPFs. We therefore suggest that food health potential should be first defined by its degree of processing.

    The US Department of Energy has initiated an integrated demonstration program to develop and compare new technologies for the characterization of uranium-contaminated soils. As part of this effort, a performance-assessment task was funded in February, 1993 to evaluate the field tested technologies. Performance assessment can be cleaned as the analysis that evaluates a system's, or technology's, ability to meet the criteria specified for performance. Four new technologies were field tested at the Fernald Environmental Management Restoration Co. in Ohio. In the next section, the goals of this performance assessment task are discussed. The following section discusses issues that must be resolved if the goals are to be successfully met. The author concludes with a discussion of the potential benefits to performance assessment of the approach taken. This paper is intended to be the first of a series of documentation that describes the work. Also in this proceedings is a paper on the field demonstration at the Fernald site and a description of the technologies (Tidwell et al, 1993) and a paper on the application of advanced geostatistical techniques (Rautman, 1993). The overall approach is to simply demonstrate the applicability of concepts that are well described in the literature but are not routinely applied to problems in environmental remediation, restoration, and waste management. The basic geostatistical concepts are documented in Clark (1979) and in Issaks and Srivastava (1989). Advanced concepts and applications, along with software, are discussed in Deutsch and Journel (1992). Integration of geostatistical modeling with a decision-analytic framework is discussed in Freeze et al (1992). Information-theoretic and probabilistic concepts are borrowed from the work of Shannon (1948), Jaynes (1957), and Harr (1987). The author sees the task as one of introducing and applying robust methodologies with demonstrated applicability in other fields to the problem at hand

    Purdue University Calumet (Purdue) and Argonne National Laboratory (Argonne) have conducted an independent study to identify deployable technologies that could help the BP Whiting Refinery, and other petroleum refineries, meet future wastewater discharge limits. This study has been funded by BP. Each organization tested a subset of the target technologies and retains sole responsibility for its respective test design and implementation, quality assurance and control, test results obtained from each of the technologies, and corresponding conclusions and recommendations. This project was divided in two phases and modules. This report summarizes the work conducted by Argonne in Phase II Module 3 (Bench Scale Testing). Other Modules are discussed elsewhere (Emerging Technologies and Approaches to Minimize Discharges into Lake Michigan, Phase 2, Modules 1-3 Report, April 2011, prepared for BP Americas by the Argonne - Purdue Task Force). The goal of this project was to identify and assess available and emerging wastewater treatment technologies for removing mercury and vanadium from the Whiting Refinery wastewater and to conduct bench-scale tests to provide comparable, transparent, and uniform results across the broad range of technologies tested. After the bench-scale testing phase, a previously developed decision matrix was refined and applied by Argonne to process and review test data to estimate and compare the preliminary performance, engineering configuration, preliminary cost, energy usage, and waste generation of technologies that were shown to be able to remove Hg and/or V to below the target limit at the bench scale. The data were used as the basis to identify the best candidates for further testing at the bench or pilot scale on a slip stream of effluent to lake (ETL) or clarifier effluent (CE) at the Whiting Refinery to determine whether future limits could be met and to generate other pertinent data for scale-up and sustainability evaluation. As a result of

    With the enactment of the 2009 American Recovery and Reinvestment Act, U.S. President Obama made a public commitment to a new approach to energy production and transmission in the United States. It features installing smart meters and related technologies in residential homes, as part of transforming the current electrical grid into a “smart grid.” Realizing this transformation requires consumers to accept these new technologies and take advantage of the opportunities that they create. We use methods from behavioral decision research to understand consumer beliefs about smart meters, including in-depth mental models interviews and a follow-up survey with a sample of potential smart meter customers of a major U.S. mid-Atlantic electricity utility. In both the surveys and the interviews, most respondents reported wanting smart meters. However, these preferences were often based on erroneous beliefs regarding their purpose and function. Respondents confused smart meters with in-home displays and other enabling technologies, while expecting to realize immediate savings. They also perceived risks, including less control over their electricity usage, violations of their privacy, and increased costs. We discuss the policy implications of our results. - Highlights: ► We outline normative risks and benefits of smart meters from scientific literature. ► We examine consumer perceptions of smart meters via interviews and surveys. ► Smart meter desire stems from consumer misconceptions about purpose and function. ► Appropriate communications may prevent consumer protests against the smart grid.

    2002-01-01

    Full Text Available The types of technology change catalyzed by research interventions in integrated natural resource management (INRM are likely to require much more social negotiation and adaptation than are changes related to plant breeding, the dominant discipline within the system of the Consultative Group on International Agricultural Research (CGIAR. Conceptual models for developing and delivering high-yielding varieties have proven inadequate for delivering natural resource management (NRM technologies that are adopted in farmers' fields. Successful INRM requires tools and approaches that can blend the technical with the social, so that people from different disciplines and social backgrounds can effectively work and communicate with each other. This paper develops the "follow-the-technology" (FTT approach to catalyzing, managing, and evaluating rural technology change as a framework that both "hard" and "soft" scientists can work with. To deal with complexity, INRM needs ways of working that are adaptive and flexible. The FTT approach uses technology as the entry point into a complex situation to determine what is important. In this way, it narrows the research arena to achievable boundaries. The methodology can also be used to catalyze technology change, both within and outside agriculture. The FTT approach can make it possible to channel the innovative potential of local people that is necessary in INRM to "scale up" from the pilot site to the landscape. The FTT approach is built on an analogy between technology change and Darwinian evolution, specifically between "learning selection" and natural selection. In learning selection, stakeholders experiment with a new technology and carry out the evolutionary roles of novelty generation, selection, and promulgation. The motivation to participate is a "plausible promise" made by the R&D team to solve a real farming problem. Case studies are presented from a spectrum of technologies to show that repeated

    Mapping of tissue structure at the cellular, circuit, and organ-wide scale is important for understanding physiological and biological functions. A bio-electrochemical technique known as CLARITY used for three-dimensional anatomical and phenotypical mapping within transparent intact tissues has been recently developed. This method provided a major advance in understanding the structure-function relationships in circuits of the nervous system and organs by using whole-body clearing. Thus, in the present study, we aimed to improve the original CLARITY procedure and developed specific CLARITY protocols for various intact organs. We determined the optimal conditions for reducing bubble formation, discoloration, and depositing of black particles on the surface of tissue, which allowed production of clearer organ images. We also determined the appropriate replacement cycles of clearing solution for each type of organ, and convincingly demonstrated that 250-280 mA is the ideal range of electrical current for tissue clearing. We then acquired each type of cleared organs including brain, pancreas, liver, lung, kidney, and intestine. Additionally, we determined the images of axon fibers of hippocampal region, the Purkinje layer of cerebellum, and vessels and cellular nuclei of pancreas. CLARITY is an innovative biochemical technology for the structural and molecular analysis of various types of tissue. We developed improved CLARITY methods for clearing of the brain, pancreas, lung, intestine, liver, and kidney, and identified the appropriate experimental conditions for clearing of each specific tissue type. These optimized methods will be useful for the application of CLARITY to various types of organs.

    For the assessment of eye irritation, one alternative test may not completely replace the rabbit Draize test. In the present study, we examined the predictive potential of a tiered approach analyzing the results from several alternatives (i.e., the Short Time Exposure (STE) test, the EpiOcular assay, the Hen's Egg Test-Chorioallantoic Membrane (HET-CAM) assay and the Bovine Corneal Opacity and Permeability (BCOP) assay) for assessing Globally Harmonized System (GHS) eye irritation categories. Fifty-six chemicals including alcohols, surfactants, and esters were selected with a balanced GHS category and a wide range of chemical classes. From a standpoint of both assessable sample numbers and predictive accuracy, the more favorable tiered approach was considered to be the two-stage bottom-up tiered approach combining the STE test, the EpiOcular assay followed by the BCOP assay (accuracy 69.6%, under prediction rate 8.9%). Moreover, a more favorable predictive capacity (accuracy 71.4%, under prediction rate 3.6%) was obtained when high volatile alcohols/esters with vapor pressures >6 kilopascal (kPa) at 25°C were evaluated with EpiOcular assay instead of the STE test. From these results, the two-stage bottom-up tiered approach combining the STE test, the EpiOcular assay followed by the BCOP assay might be a promising method for the classification of GHS eye irritation category (Not classified (NC), Category 2 (Cat. 2), and Category 1 (Cat. 1)) for a wide range of test chemicals regardless of solubility.

    To investigate the impact of integrating a medical intensivist into a cardiac care unit (CCU) multidisciplinary team on the outcomes of CCU patients. We conducted a retrospective cohort study of 2239 CCU admissions between July 1, 2011, and July 1, 2013, which constituted patients admitted in the 12 months before and 12 months after the introduction of intensivists into the CCU multidisciplinary team. This team included a cardiologist, a medical intensivist, medical house staff, nurses, a pharmacist, a dietitian, and physical and respiratory therapists. The primary outcome was CCU mortality. Secondary outcomes included hospital mortality, CCU length of stay, hospital length of stay, and duration of mechanical ventilation. After the implementation of a multidisciplinary team approach, there was a significant decrease in both adjusted CCU mortality (3.5% vs 5.9%; P=.01) and hospital mortality (4.4% vs 11.1%; Pmultidisciplinary team approach in which an intensivist and a cardiologist comanage the critical care of CCU patients is feasible and may result in better patient outcomes.

    Membrane bioreactor (MBR) technology is a very reliable and extensively tested solution for biological wastewater treatment. Nowadays, separate treatment of highly polluted wastewater streams especially from hospitals and other health care facilities is currently under investigation worldwide. In this context, the MBR technology will play a decisive role because an effluent widely cleaned up from solids and nutrients is absolutely mandatory for a subsequent further elimination of organic trace pollutants. Taking hospital wastewater as an example, the aim of this study was to investigate to what extent MBR technology is an adequate 'pre-treatment' solution for further elimination of trace pollutants. Therefore, we investigated - within a 2-year period - the performance of a full-scale hospital wastewater treatment plant (WWTP) equipped with a MBR by referring to conventional chemical and microbiological standard parameters. Furthermore, we measured the energy consumption and tested different operating conditions. According to our findings the MBR treatment of the hospital wastewater was highly efficient in terms of the removal of solids and nutrients. Finally, we did not observe any major adverse effects on the operation and performance of the MBR system which potentially could derive from the composition of the hospital wastewater. In total, the present study proved that MBR technology is a very efficient and reliable treatment approach for the treatment of highly polluted wastewater from hospitals and can be recommended as a suitable pre-treatment solution for further trace pollutant removal.

    The vast majority of Malaysia's fishermen are located in rural areas, specifically in the Western and Eastern coastal regions of Peninsular Malaysia and the Sabah and Sarawak central zones. In these areas, the fishing industry is relied upon as a major economic contributor to the region's residents. Despite the widespread application of various modern technologies into the fishing industry (i.e., GPS, sonar, echo sounder, remote sensing), and the Malaysian government's efforts to encourage their adoption, many small-scale fishermen in the country's rural areas continue to rely on traditional fishing methods. This refusal to embrace new technologies has resulted in significant losses in fish yields and needed income, and has raised many questions regarding the inputs to decision making of the fishermen. Drawing on multiple literatures, in this article we argue for the use of a mental model approach to gain an in-depth understanding of rural Malaysian fishermen's choices of technology adoption according to four main constructs--prior experience, knowledge, expertise and beliefs or values. To provide needed inputs to agricultural specialists and related policy makers for the development of relevant plans of action, this article aims to provide a way forward for others to understand dispositional barriers to technology adoption among fishermen who use traditional methods in non-Western contexts. © 2013 International Union of Psychological Science.

    Both academics and practitioners agree that critical thinking skills are necessary to provide safe and comprehensive nursing care. In order to promote the development of critical thinking, nurse educators need to keep the teaching/learning process captivating and interesting using active learning environments. These can be implemented by using modern information and communication technologies that are simple, fun, and time and cost effective. The goal of our study was to design and test an approach, which allows individual and fast acquisition of critical thinking skills with the use of information and communication technology. A combination of qualitative and quantitative research design was implemented. The study consisted of a quasi-experiment (phases 1-3): (1) pre-test discussion board, (2) use of e-contents based on the presented approach, and (3) post-test discussion board. The participants' opinion about the presented approach was identified in phase 4.

Terahertz (THz) and optical metamaterials are usually fabricated by traditional planar-patterning approaches, while the majority of practical applications require metamaterials with 3D resonators. Making arrays of precise 3D micro- and nanoresonators is still a challenging problem. Here we present a versatile set of approaches to fabrication of metamaterials with 3D resonators rolled-up from strained films, demonstrate novel THz metamaterials/systems, and show giant polarization rotation by several chiral metamaterials/systems. The polarization spectra of chiral metamaterials on semiconductor substrates exhibit ultrasharp quasiperiodic peaks. Application of 3D printing allowed assembling more complex systems, including the bianisotropic system with optimal microhelices, which showed an extreme polarization azimuth rotation of 85° with drop by 150° at a frequency shift of 0.4%. We refer the quasiperiodic peaks in the polarization spectra of metamaterial systems to the interplay of different resonances, including peculiar chiral waveguide resonance. Formed metamaterials cannot be made by any other presently available technology. All steps of presented fabrication approaches are parallel, IC-compatible and allow mass fabrication with scaling of rolled-up resonators up to visible frequencies. We anticipate that the rolled-up meta-atoms will be ideal building blocks for future generations of commercial metamaterials, devices and systems on their basis.

    Attenuation correction for whole-body PET/MRI is challenging. Most commercial systems compute the attenuation map from MRI using a four-tissue segmentation approach. Bones, the most electron-dense tissue, are neglected because they are difficult to segment. In this work, the authors build on this segmentation approach by adding bones using a registration technique and assessing its performance on human PET images. Twelve oncology patients were imaged with FDG PET/CT and MRI using a Turbo-FLASH pulse sequence. A database of 121 attenuation correction quality CT scans was also collected. Each patient MRI was compared to the CT database via weighted heuristic measures to find the "most similar" CT in terms of body geometry. The similar CT was aligned to the MRI with a deformable registration method. Two MRI-based attenuation maps were computed. One was a standard four-tissue segmentation (air, lung, fat, and lean tissue) using basic image processing techniques. The other was identical, except the bones from the aligned CT were added. The PET data were reconstructed with the patient's CT-based attenuation map (the silver standard) and both MRI-based attenuation maps. The relative errors of the MRI-based attenuation corrections were computed in 14 standardized volumes of interest, in lesions, and over whole tissues. The squared Pearson correlation coefficient was also calculated over whole tissues. Statistical testing was done with ANOVAs and paired t-tests. The MRI-based attenuation correction ignoring bone had relative errors ranging from -37% to -8% in volumes of interest containing bone. By including bone, the magnitude of the relative error was reduced in all cases (pbone was improved from a mean of -7.5% to 2% (pbone reduced the magnitude of relative error in three cases (pbone slightly increased relative error in lung from 7.7% to 8.0% (p=0.002), in fat from 8.5% to 9.2% (pbone from -14.6% to 1.3% (pbone was included or not.

Then, we identify the most important trends in this field, and give a real practical case for the application of this approach. The results show that the attempt methods are much better than traditional teaching methods.

  20. Green Materials Science and Engineering Reduces Biofouling: Approaches for Medical and Membrane-based Technologies

    2015-03-01

    Full Text Available Numerous engineered and natural environments suffer deleterious effects from biofouling and/or biofilm formation. For instance, bacterial contamination on biomedical devices pose serious health concerns. In membrane-based technologies, such as desalination and wastewater reuse, biofouling decreases membrane lifetime and increases the energy required to produce clean water. Traditionally, approaches have combatted bacteria using bactericidal agents. However, due to globalization, a decline in antibiotic discovery, and the widespread resistance of microbes to many commercial antibiotics and metallic nanoparticles, new materials and approaches to reduce biofilm formation are needed. In this mini-review, we cover the recent strategies that have been explored to combat microbial contamination without exerting evolutionary pressure on microorganisms. Renewable feedstocks, relying on structure-property relationships, bioinspired/nature-derived compounds, and green processing methods are discussed. Greener strategies that mitigate biofouling hold great potential to positively impact human health and safety.

    The overall aim of this thesis is to examine the interactions between the Danish wind turbine industry and the Test Station for Wind Turbines. Because these interactions are concerning technological innovation, it follows that the innovation processes within the enterprises must be analyzed and modelled. The study is carried out as an iterative model-developing process using case study methods. The findings from some less structured interviews are discussed with literature and forms a basis for models and new interviews. The thesis is based on interviews with 20 R and D engineers in the Danish wind turbine industry, 7 engineers at The Test Station and 7 people involved in wind power abroad (American and British). The theoretical frame for this thesis is sociology/organizational theory and industrial engineering. The thesis consists of five main sections, dealing with technology and knowledge, innovation processes, organizational culture, innovation and interaction between the Test Station's research activities and the companies' innovation processes, and finally interaction through the Test Stations certification activity. First a taxonomy for technology and knowledge is established in order to clarify what kind of technology the interactions are all about, and what kind of knowledge is transferred during the interactions. This part of the thesis also contains an analysis of the patents drawn by the Danish wind turbine industry. The analysis shows that the Danish wind turbine industry do not use patents. Instead the nature of the technology and the speed of innovation are used to protect the industry's knowledge. (EG) (192 refs.)

    The start of the production of bottom-fermented beer in Barcelona, at the beginning of the 1870s, resulted in a drink with organoleptic characteristics that made it more popular: less alcohol and more frothy and transparent than the top-fermented beer made until then. Its production resulted in greater investment in new technologies, including the production of artificial refrigeration, which led to a marked increase in fixed costs. This meant, on the one hand, external financing requirements...

  3. Non-thermodynamic approach to including bombardment-induced post-cascade redistribution of point defects in dynamic Monte Carlo code

    Ignatova, V A; Katardjiev, I V

    2003-01-01

    The redistribution of the elements as a result of atomic relocations produced by the ions and the recoils due to the ballistic and transport processes is investigated by making use of a dynamic Monte Carlo code. Phenomena, such as radiation-enhanced diffusion (RED) and bombardment-induced segregation (BIS) triggered by the ion bombardment may also contribute to the migration of atoms within the target. In order to include both RED and BIS in the code, we suggest an approach which is considered as an extension of the binary collision approximation, i.e. it takes place 'simultaneously' with the cascade and acts as a correction to the particle redistribution for low energies. Both RED and BIS models are based on the common approach to treat the transport processes as a result of a random migration of point defects (vacancies and interstitials) according to a probability given by a pre-defined Gaussian. The models are tested and the influence of the diffusion and segregation is illustrated in the cases of 12 keV ...

    Assessment of variant solutions developed for a building investment project needs to be made at the stage of planning. While considering alternative solutions, the investor defines various criteria, but a direct evaluation of the degree of their fulfilment by developed variant solutions can be very difficult. In practice, there are different methods which enable the user to include a large number of parameters into an analysis, but their implementation can be challenging. Some methods require advanced mathematical computations, preceded by complicating input data processing, and the generated results may not lend themselves easily to interpretation. Hence, during her research, the author has developed a systemic approach, which involves several methods and whose goal is to compare their outcome. The final stage of the proposed method consists of graphic interpretation of results. The method has been tested on a variety of building and development projects.

    In our research project a suitable method has been developed related the technological aspect of the environmental assessment of land use changes caused by climate change. We have prepared an eco-balance (environmental inventory) to the environmental effects classification in life-cycle approach in connection with the typical agricultural / forest and tree utilization technologies. The use of balances and environmental classification makes possible to compare land-use technologies and their environmental effects per common functional unit. In order to test our environmental analysis model, we carried out surveys in sample of forest stands. We set up an eco-balance of the working systems of intermediate cutting and final harvest in the stands of beech, oak, spruce, acacia, poplar and short rotation energy plantations (willow, poplar). We set up the life-cycle plan of the surveyed working systems by using the GaBi 6.0 Professional software and carried out midpoint and endpoint impact assessment. Out of the results, we applied the values of CML 2001 - Global Warming Potential (GWP 100 years) [kg CO2-Equiv.] and Eco-Indicator 99 - Human health, Climate Change [DALY]. On the basis of the values we set up a ranking of technology. By this, we received the environmental impact classification of the technologies based on carbon footprint. The working systems had the greatest impact on global warming (GWP 100 years) throughout their whole life cycle. This is explained by the amount of carbon dioxide releasing to the atmosphere resulting from the fuel of the technologies. Abiotic depletion (ADP foss) and marine aquatic ecotoxicity (MAETP) emerged also as significant impact categories. These impact categories can be explained by the share of input of fuel and lube. On the basis of the most significant environmental impact category (carbon footprint), we perform the relative life cycle contribution and ranking of each technologies.

    improve the methodology for defining technology requirements for regulators in the future. The biggest shortcoming of the presented research program was the absence of the explicit definition, generation and analysis of potential human-automation architectures. Failure to execute this step in the research process resulted in less efficient evaluation of the candidate prototypes technologies in addition to the complete absence of different approaches to human-automation cooperation. For example, all of the prototype technologies that were evaluated in the research program assumed a human-automation architecture that relied on serial processing from the automation to the human. While this type of human-automation architecture is typical across many different technologies and in many different domains, it ignores different architectures where humans and automation work in parallel. Defining potential human-automation architectures a priori also allows regulators to develop scenarios that will stress the performance boundaries of the technology during the evaluation phase. The importance of adding this step of generating and evaluating candidate human-automation architectures prior to formal empirical evaluation is discussed.

    Have the advancement of assisted reproductive technologies (ART) and changes in the incidence of specific causes of infertility-altered ectopic pregnancy (EP) rates following ART over time in the UK? EP rates in the UK following IVF/ICSI have progressively decreased, and this appears to be associated with a reduction in the incidence of tubal factor infertility and the increased use of both a lower number of embryos transferred and extended embryo culture. Historically, EP rates following ART are known to have increased over time. However, the impact of progress in ART procedures and changes in both policy and the incidence of specific causes of infertility on the overall EP rate in the UK has yet to be studied. A population-based retrospective analysis was carried out on all pregnancies following ART cycles carried out in the UK between 2000 and 2012 included in the anonymized database of the Human Fertilisation and Embryology Authority. Overall, 161 967 treatment cycles resulting in a pregnancy were included in the analysis. Among them, 8852 pregnancies occurred after intrauterine insemination (IUI) and 153 115 following IVF/ICSI. During this period of 12 years, ∼1.4% (n = 2244) of all pregnancies following ART were an EP. Crude EP rates were significantly higher after IVF/ICSI when compared with following IUI (1.4 versus 1.1%, P = 0.043). The incidence of EP decreased significantly over time for IVF/ICSI cycles [incidence rate ratios (IRR) 0.96 per year, 95% confidence interval (CI) 0.94-0.97], but not after IUI (IRR 0.96 per year, 95% CI 0.91-1.03).Among pregnancies resulting from IVF/ICSI, multivariable logistic regression analysis demonstrated that the major risk factor for EP was the presence of tubal infertility [adjusted odds ratio (aOR) 2.23, 95% CI 1.93-2.58), followed by the increased number of embryos transferred (aOR 1.29 for 2 versus 1 embryo transferred, 95% CI 1.11-1.49; aOR 1.69 for 3 or more versus 1 embryo transferred, 95% CI 1.35-2.11).

    2014-05-01

    Full Text Available In this paper we argue for the need to apply a cognitive approach to understand deep dynamics and determinants of technological evolutions. After examining main contributions from innovation studies to the conceptualization of innovation and change in complex socio-technical environments, we highlight the contribution coming from the application of the cognitive approach to evolutionary studies on technologies and we introduce the concept of technological memory as an interpretative tool to understand those changes. We discuss our hypothesis with reference to several observations carried out in different local contexts – Mexico, India and Italy – in relation to technological change in the water sector. In those cases deliberate attempts to substitute traditional technologies with modern ones led to interesting trajectories of change ranging from the collapse of old technologies to the development of multifaceted hybridization patterns.

  13. Evaluation of a Mixed Method Approach for Studying User Interaction with Novel Building Control Technology

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available Energy-efficient building performance requires sophisticated control systems that are based on realistic occupant behaviour models. To provide robust data for the development of these models, research studies in real-world settings are needed. Yet, such studies are challenging and necessitate careful design in terms of data collection methods and procedures. This paper describes and critiques the design of a mixed methods approach for occupant behaviour research. It reviews the methodology developed for a longitudinal study in a real-world office environment where occupants’ experience with a novel facade technology (electrochromic glazing was investigated. The methodology integrates objective physical measurements, observational data and self-reported experience data. Using data from one day of the study, this paper illustrates how the different sources can be combined in order to derive an in-depth understanding of the interplay between external daylight conditions, characteristics of the facade technology, occupant interaction with the technology and the resulting occupant experience. It was found that whilst the individual methods may be affected by practical limitations, these can be partially offset by combining physical measurements and observations with self-reported data. The paper critically evaluates the individual techniques, as well as the benefits of their integration and makes recommendations for the design of future occupant behaviour studies in real-world settings.

    2017-06-01

    Full Text Available Impaired awareness of hypoglycemia has been found to be prevalent in 20% to 40% of people with type 1 diabetes. If a similar prevalence exists in Koreans with type 1 diabetes, at a minimum, thousands of people with type 1 diabetes suffer at least one unpredicted episode of severe hypoglycemia per year in Korea. For patients with problematic hypoglycemia, an evidence-based stepwise approach was suggested in 2015. The first step is structured education regarding multiple daily injections of an insulin analog, and the second step is adding a technological intervention, such as continuous subcutaneous insulin infusion or real-time continuous glucose monitoring. The next step is a sensor-augmented pump, preferably with a low glucose suspension feature or very frequent contact, and the final step is islet or pancreas transplantation. In Korea, however, none of these treatments are reimbursed by the National Health Insurance, and thus have not been widely implemented. The low prevalence of type 1 diabetes means that Korean physicians are relatively unfamiliar with the new technologies in this field. Therefore, the roles of new technologies and pancreas or islet transplantation in the treatment of problematic hypoglycemia need to be defined in the current clinical setting of Korea.

    Full Text Available The analysis of Carbon Footprint (CF for technology of hydrogen production from cleaned coke oven gas was performed. On the basis of real data and simulation calculations of the production process of hydrogen from coke gas, emission indicators of carbon dioxide (CF were calculated. These indicators are associated with net production of electricity and thermal energy and direct emission of carbon dioxide throughout a whole product life cycle. Product life cycle includes: coal extraction and its transportation to a coking plant, the process of coking coal, purification and reforming of coke oven gas, carbon capture and storage. The values were related to 1 Mg of coking blend and to 1 Mg of the hydrogen produced. The calculation is based on the configuration of hydrogen production from coke oven gas for coking technology available on a commercial scale that uses a technology of coke dry quenching (CDQ. The calculations were made using ChemCAD v.6.0.2 simulator for a steady state of technological process. The analysis of carbon footprint was conducted in accordance with the Life Cycle Assessment (LCA.

  16. A public perspective on the adoption of microgeneration technologies in New Zealand: A multivariate probit approach

    International Nuclear Information System (INIS)

    Baskaran, Ramesh; Managi, Shunsuke; Bendig, Mirko

    2013-01-01

    The growing demand for electricity in New Zealand has led to the construction of new hydro-dams or power stations that have had environmental, social and cultural effects. These effects may drive increases in electricity prices, as such prices reflect the cost of running existing power stations as well as building new ones. This study uses Canterbury and Central Otago as case studies because both regions face similar issues in building new hydro-dams and ever-increasing electricity prices that will eventually prompt households to buy power at higher prices. One way for households to respond to these price changes is to generate their own electricity through microgeneration technologies (MGT). The objective of this study is to investigate public perception and preferences regarding MGT and to analyze the factors that influence people’s decision to adopt such new technologies in New Zealand. The study uses a multivariate probit approach to examine households’ willingness to adopt any one MGT system or a combination of the MGT systems. Our findings provide valuable information for policy makers and marketers who wish to promote effective microgeneration technologies. - Highlights: ► We examine New Zealand households’ awareness level for microgeneration technologies (MGT) and empirically explore the factors that determine people’s willingness to adopt for MGT. ► The households are interested and willing to adopt the MGT systems. ► Noticeable heterogeneity exists between groups of households in adopting the MGT. ► No significant regional difference exists in promoting solar hot water policies. ► Public and private sectors incentives are important in promoting the MGT

    The food habit is involved in the onset and development of lifestyle-related diseases. In this review I would like to describe a historical case of vitamin B1 deficiency, as well as our case study of fatty acid metabolism abnormality due to carnitine deficiency. In history, the army and navy personnel in Japan at the end of the 19th century received food rations based on a high-carbohydrate diet including white rice, resulting in the onset of beriberi. An epidemiological study by Kenkan Takaki revealed the relationship between the onset of beriberi and rice intake. Then, Takaki was successful in preventing the onset of beriberi by changing the diet. However, the primary cause had yet to be elucidated. Finally, Christian Eijkman established an animal model of beriberi (chickens) showing peripheral neuropathy, and he identified the existence of an anti-beriberi substance, vitamin B1. This is an example of the successful control of a disease by integrating the results of epidemiological and experimental studies. In our study using a murine model of fatty acid metabolism abnormality caused by carnitine deficiency, cardiac abnormality and fatty liver developed depending on the amount of dietary fat. In addition, the mice showed disturbance of orexin neuron activity related to the sleep-arousal system, which is involved in fatigue symptoms under fasting condition, one of the states showing enhanced fatty acid metabolism. These findings suggest that fatty acid toxicity is enhanced when the mice are more dependent on fatty acid metabolism. Almost simultaneously, a human epidemiological study showed that narcolepsy, which is caused by orexin system abnormality, is associated with the polymorphism of the gene coding for carnitine palmitoyltransferase 1B, which is involved in carnitine metabolism. To understand the pathological mechanism of fatty acid toxicity, not only an experimental approach using animal models, but also an epidemiological approach is necessary. The

In this paper, a general approach for loss of life estimation is proposed which includes three elements: (1) the assessment of physical effects associated with the event; (2) determination of the number of exposed persons (taking into account warning and evacuation); and (3) determination of mortality amongst the population exposed. The typical characteristics of and modelling approaches for these three elements are discussed. This paper focuses on 'small probability-large consequences' events within the engineering domain. It is demonstrated how the proposed approach can be applied to various case studies, such as tunnel fires, earthquakes and flood events.

    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.

    South Korea is the 10th largest energy consumer in the world because of the poor country of natural resources such as petroleum, coal, and natural gas. It is essential to solve the energy difficulty of secure supply and demand of national energy. We established the energy technology roadmap to prepare for the next 10 years. We clustered 3 core technological sectors such as technology for high oil prices, the United nations framework for climate change, and the hydrogen economy. But we didn't prioritize the weights of energy technology development in energy technology roadmap. To allocate the finite resources efficiently, we cluster the preferred groups and non-preferred groups by the data envelopment analysis (DEA) approach. Through the scientific decision making approach, we can allocate R and D capacity, budget, and infrastructures efficiently to produce outstanding R and D outputs. (auth)

    Full Text Available Fusarium verticillioides is considered one of the most important global sources of fumonisins contamination in food and feed. Corn is one of the main commodities produced in the Northeastern Region of Brazil. The present study investigated potential mycotoxigenic fungal strains belonging to the F. verticillioides species isolated from corn kernels in 3 different Regions of the Brazilian State of Pernambuco. A polyphasic approach including classical taxonomy, molecular biology, MALDI-TOF MS and MALDI-TOF MS/MS for the identification and characterisation of the F. verticillioides strains was used. Sixty F. verticillioides strains were isolated and successfully identified by classical morphology, proteomic profiles of MALDI-TOF MS, and by molecular biology using the species-specific primers VERT-1 and VERT-2. FUM1 gene was further detected for all the 60 F. verticillioides by using the primers VERTF-1 and VERTF-2 and through the amplification profiles of the ISSR regions using the primers (GTG5 and (GACA4. Results obtained from molecular analysis shown a low genetic variability among these isolates from the different geographical regions. All of the 60 F. verticillioides isolates assessed by MALDI-TOF MS/MS presented ion peaks with the molecular mass of the fumonisin B1 (721.83 g/mol and B2 (705.83 g/mol.

    Full Text Available Cross-cultural investigation of psychopathy measures is important for clarifying the nomological network surrounding the psychopathy construct. The Psychopathic Personality Inventory-Revised (PPI-R is one of the most extensively researched self-report measures of psychopathic traits in adults. To date however, it has been examined primarily in North American criminal or student samples. To address this gap in the literature, we examined PPI-R's reliability, construct validity and factor structure in non-criminal individuals (N = 227 in Sweden, using a multimethod approach including psychophysiological correlates of empathy for pain. PPI-R construct validity was investigated in subgroups of participants by exploring its degree of overlap with (i the Psychopathy Checklist: Screening Version (PCL:SV, (ii self-rated empathy and behavioral and physiological responses in an experiment on empathy for pain, and (iii additional self-report measures of alexithymia and trait anxiety. The PPI-R total score was significantly associated with PCL:SV total and factor scores. The PPI-R Coldheartedness scale demonstrated significant negative associations with all empathy subscales and with rated unpleasantness and skin conductance responses in the empathy experiment. The PPI-R higher order Self-Centered Impulsivity and Fearless Dominance dimensions were associated with trait anxiety in opposite directions (positively and negatively, respectively. Overall, the results demonstrated solid reliability (test-retest and internal consistency and promising but somewhat mixed construct validity for the Swedish translation of the PPI-R.

    2012-01-01

    Interest in the field of patient safety incident reporting and analysis with respect to Health Information Technology (HIT) has been growing over recent years as the development, implementation and reliance on HIT systems becomes ever more prevalent. One of the rationales for capturing patient safety incidents is to learn from failures in the delivery of care and must form part of a feedback loop which also includes analysis; investigation and monitoring. With the advent of new technologies and organizational programs of delivery the emphasis is increasingly upon analyzing HIT incidents. This thematic review had two objectives, to test the applicability of a framework specifically designed to categorize HIT incidents and to review the Welsh incidents as communicated via the national incident reporting system in order to understand their implications for healthcare. The incidents were those reported as IT/ telecommunications failure/ overload. Incidents were searched for within a national reporting system using a standardized search strategy for incidents occurring between 1st January 2009 and 31st May 2011. 149 incident reports were identified and classified. The majority (77%) of which were machine related (technical problems) such as access problems; computer system down/too slow; display issues; and software malfunctions. A further 10% (n = 15) of incidents were down to human-computer interaction issues and 13% (n = 19) incidents, mainly telephone related, could not be classified using the framework being tested. On the basis of this review of incidents, it is recommended that the framework be expanded to include hardware malfunctions and the wrong record retrieved/missing data associated with a machine output error (as opposed to human error). In terms of the implications for clinical practice, the incidents reviewed highlighted critical issues including the access problems particularly relating to the use of mobile technologies.

    Isenhower, Larry Donald

    2009-01-28

    Innovation Partners proposed and successfully demonstrated in this SBIR Phase I grant a software/hardware co-design approach to reduce both the difficulty and time to implement Field Programmable Gate Array (FPGA) solutions to data acquisition and specialized computational applications. FPGAs can require excessive time for programming and require specialized knowledge that will be greatly reduced by the company's solution. Not only are FPGAs ideal for DAQ and embedded solutions, they can also be the best solution to specialized signal processing to replace Digital Signal Processors (DSPs). By allowing FPGA programming to be done in C with the equivalent of a simple compilation, algorithm changes and improvements can be implemented decreasing the life-cycle costs and allow subsitution of new FPGA designs staying above the technological details.

    Full Text Available Despite its acknowledged benefits for health promotion, the full potential of persuasive technology is not (yet reached in regard to usability, effectiveness, and reproducibility. It often lacks an effective combination of technical features and behavior change strategies. This paper presents a multidisciplinary approach, addressing both aspects. It builds on the frameworks of situated Cognitive Engineering and Intervention Mapping. The approach generates building blocks from theory originating from different relevant disciplines; it specifies change objectives and requirements, described in the context of use, for intervention (strategy and interaction (technology; it evaluates process, effect and impact, whereby claims on interaction and intervention are validated. To cope with language barriers between developers from different disciplines, the approach is presented as a guideline, illustrated with a case study. This approach is expected to contribute to a sound design rationale, a broad reach and ongoing use of the technology, and larger results in regard to health promotion.

    2014-08-01

    In the health field, technologies of care relations are in the scope of the worker-user encounter, implying intersubjectivity with the development of relationships between subjects, resulting in action. Evaluation studies synthesize knowledge produced on the consequences of using these technologies for society. This anthropological study aims to understand the perception of the elderly regarding the resolution capability and effectiveness of the acts produced in health care relationships in the context of the Family Health Strategy (ESF). The group studied consisted of 57 elderly residents in Bambui, State of Minas Gerais, Brazil. The model of signs, meanings and actions was used for collecting and analyzing data and the semi-structured interview was applied as a research technique. Elderly individuals assess resolution capability and effectiveness of the acts of care in the ESF as negative, with relation to the quality of user and professional interaction. The ESF is not effective and the desired change in the health care model has not occurred in practice. It repeats the centrality of the medical-drug-procedure model that treats the disease rather than the patient, perceiving old age as a disease and illness as being related to aging.

    Full Text Available The current rapid technological changes confront researchers of learning technologies with the challenge of evaluating them, predicting trends, and improving their adoption and diffusion. This study utilizes a data-driven discourse analysis approach, namely culturomics, to investigate changes over time in the research of learning technologies. The patterns and changes were examined on a corpus of articles published over the past decade (2006-2014 in the proceedings of Chais Conference for the Study of Innovation and Learning Technologies – the leading research conference on learning technologies in Israel. The interesting findings of the exhaustive process of analyzing all the words in the corpus were that the most commonly used terms (e.g., pupil, teacher, student and the most commonly used phrases (e.g., face-to-face in the field of learning technologies reflect a pedagogical rather than a technological aspect of learning technologies. The study also demonstrates two cases of change over time in prominent themes, such as “Facebook” and “the National Information and Communication Technology (ICT program”. Methodologically, this research demonstrates the effectiveness of a data-driven approach for identifying discourse trends over time.

    The Marine Technology for Teachers and Students (MaTTS) Project implements a year-long continuum of activities beginning with educators reading and reporting on peer-reviewed publications, followed by face-to-face, hands-on weekend workshops and virtual professional development activities. Teams of teacher and student leaders then participate in an intensive, residential Summer Institute (SI) that emphasizes hands-on building of marine related technologies and exposure to career pathways through direct interactions with ocean scientists and engineers. During the school year, teachers integrate ocean science technology and data into their classrooms and participate, along with colleagues and students from their schools, in science cafes and webinars. Student leaders transfer knowledge gained by engaging their district's middle school students in ocean science activities and technologies by serving as hosts for live broadcasts that connect classrooms with ocean scientists and engineers though the Inner Space Center, a national ocean science telecommunications hub. Communication technologies bridge formal and informal learning environments, allowing MaTTS participants to interact with their fellow cohort members, scientists, and engineers both during and outside of school. Evaluation results indicate that for teachers both the weekend workshops and SI were most effective in preparing them to integrate ocean science and technology in STEM curricula and increase their ocean science content knowledge and leadership characteristics. For students the SI and the middle school interactions supported gains in knowledge, awareness, leadership skills and interest in ocean sciences and technologies, and related STEM careers. In particular, the connections made by working directly with scientists have positively impacted both student and teacher leaders. This presentation will provide an overview of the MaTTS model and early evaluation results.

    2017-01-01

    Genome-editing technology has emerged as a powerful method that enables the generation of genetically modified cells and organisms necessary to elucidate gene function and mechanisms of human diseases. The clustered regularly interspaced short palindromic repeats- (CRISPR-) associated 9 (Cas9) system has rapidly become one of the most popular approaches for genome editing in basic biomedical research over recent years because of its simplicity and adaptability. CRISPR/Cas9 genome editing has been used to correct DNA mutations ranging from a single base pair to large deletions in both in vitro and in vivo model systems. CRISPR/Cas9 has been used to increase the understanding of many aspects of cardiovascular disorders, including lipid metabolism, electrophysiology and genetic inheritance. The CRISPR/Cas9 technology has been proven to be effective in creating gene knockout (KO) or knockin in human cells and is particularly useful for editing induced pluripotent stem cells (iPSCs). Despite these progresses, some biological, technical, and ethical issues are limiting the therapeutic potential of genome editing in cardiovascular diseases. This review will focus on various applications of CRISPR/Cas9 genome editing in the cardiovascular field, for both disease research and the prospect of in vivo genome-editing therapies in the future.

    2015-01-01

    Full Text Available In the last decades, food science has greatly developed, turning from the consideration of food as mere source of energy to a growing awareness on its importance for health and particularly in reducing the risk of diseases. Such vision led to an increasing attention towards the origin and quality of raw materials as well as their derived food products. The continuous advance in molecular biology allowed setting up efficient and universal omics tools to unequivocally identify the origin of food items and their traceability. In this review, we considered the application of a genomics approach known as DNA barcoding in characterizing the composition of foodstuffs and its traceability along the food supply chain. Moreover, metabolomics analytical strategies based on Nuclear Magnetic Resonance (NMR and Mass Spectroscopy (MS were discussed as they also work well in evaluating food quality. The combination of both approaches allows us to define a sort of molecular labelling of food that is easily understandable by the operators involved in the food sector: producers, distributors, and consumers. Current technologies based on digital information systems such as web platforms and smartphone apps can facilitate the adoption of such molecular labelling.

    2014-06-01

    Full Text Available Obesity is currently an important public health problem of epidemic proportions (globesity. Inpatient rehabilitation interventions that aim at improving weight-loss, reducing obesity-related complications and changing dysfunctional behaviors, should ideally be carried out in a multidisciplinary context with a clinical team composed of psychologists, dieticians, psychiatrists, endocrinologists, nutritionists, physiotherapists, etc. Long-term outpatient multidisciplinary treatments are likely to constitute an essential aspect of rehabilitation. Internet-based technologies can improve long-term obesity rehabilitation within a collaborative approach by enhancing the steps specified by psychological and medical treatment protocols. These outcomes may be augmented further by the mHealth approach, through creating new treatment delivery methods to increase compliance and engagement. mHealth (m-health, mobile health can be defined as the practice of medicine and public health, supported by mobile communication devices for health services and information. mHealth applications which can be implemented in weight loss protocols and obesity rehabilitation are discussed, taking into account future research directions in this promising area.

    Hydrogen energy technology can be one of the best key players related to the sector of the United Nations Framework Convention on Climate Change (UNFCCC) and the hydrogen economy. Comparing to other technologies, hydrogen energy technology is more environmentally sound and friendly energy technology and has great potential as a future dominant energy carrier. Advanced nations including Korea have been focusing on the development of hydrogen energy technology R and D for the sustainable development and low carbon green society. In this paper, we applied the integrated fuzzy analytic hierarchy process (Fuzzy AHP) and the data envelopment analysis (DEA) for measuring the relative efficiency of the R and D performance in the national hydrogen energy technology development. On the first stage, the fuzzy AHP effectively reflects the vagueness of human thought. On the second stage, the DEA approach measures the relative efficiency of the national R and D performance in the sector of hydrogen energy technology development with economic viewpoints. The efficiency score can be the fundamental data for policymakers for the well focused R and D planning. (author)

    Daniel Tom-Aba

    Full Text Available The recent outbreak of Ebola Virus Disease (EVD in West Africa has ravaged many lives. Effective containment of this outbreak relies on prompt and effective coordination and communication across various interventions; early detection and response being critical to successful control. The use of information and communications technology (ICT in active surveillance has proved to be effective but its use in Ebola outbreak response has been limited. Due to the need for timeliness in reporting and communication for early discovery of new EVD cases and promptness in response; it became imperative to empower the response team members with technologies and solutions which would enable smooth and rapid data flow. The Open Data Kit and Form Hub technology were used in combination with the Dashboard technology and ArcGIS mapping for follow up of contacts, identification of cases, case investigation and management and also for strategic planning during the response. A remarkable improvement was recorded in the reporting of daily follow-up of contacts after the deployment of the integrated real time technology. The turnaround time between identification of symptomatic contacts and evacuation to the isolation facility and also for receipt of laboratory results was reduced and informed decisions could be taken by all concerned. Accountability in contact tracing was ensured by the use of a GPS enabled device. The use of innovative technologies in the response of the EVD outbreak in Nigeria contributed significantly to the prompt control of the outbreak and containment of the disease by providing a valuable platform for early warning and guiding early actions.

    Full Text Available The radial approach is widely used in the treatment of patients with coronary artery disease. We conducted a meta-analysis of published results on the efficacy and safety of the left and right radial approaches in patients undergoing percutaneous coronary procedures. A systematic search of reference databases was conducted, and data from 14 randomized controlled trials involving 6870 participants were analyzed. The left radial approach was associated with significant reductions in fluoroscopy time [standardized mean difference (SMD=-0.14, 95% confidence interval (CI=-0.19 to -0.09; P<0.00001] and contrast volume (SMD=-0.07, 95%CI=-0.12 to -0.02; P=0.009. There were no significant differences in rate of procedural failure of the left and the right radial approaches [risk ratios (RR=0.98; 95%CI=0.77-1.25; P=0.88] or procedural time (SMD=-0.05, 95%CI=0.17-0.06; P=0.38. Tortuosity of the subclavian artery (RR=0.27, 95%CI=0.14-0.50; P<0.0001 was reported more frequently with the right radial approach. A greater number of catheters were used with the left than with the right radial approach (SMD=0.25, 95%CI=0.04-0.46; P=0.02. We conclude that the left radial approach is as safe as the right radial approach, and that the left radial approach should be recommended for use in percutaneous coronary procedures, especially in percutaneous coronary angiograms.

  12. A unifying approach to the clinical diagnosis of melanoma including “D” for “Dark” in the ABCDE criteria

    2014-01-01

    Current clinical approaches to melanoma diagnosis have not been associated with a decrease in mortality from this cancer. The components of the new approach presented are, first, a screening examination to look for any lesion that stands out because of being dark, different, or changing; second, when a single lesion is recognized to be of concern for any reason, that lesion is then evaluated in more detail utilizing the ABCDE criteria, with the “D” signifying “Dark” and not “6 mm Diameter” in this mnemonic; and, third, additional discussion of the “ugly duckling” sign and of the recognition of nodular melanomas. Since the Georgia Society of Dermatology and Dermatologic Surgery was the first state or national society to endorse this approach, I refer to it as the Georgia approach. PMID:25396093

    2016-10-01

    Balanced Scorecard (BSC) is a strategic evaluation tool using both financial and non-financial indicators to determine the business performance of organizations or companies. In this paper, a new integrated approach based on the Balanced Scorecard (BSC) and multi-criteria decision making (MCDM) methods are proposed to evaluate the performance of research centers of research and technology organization (RTO) in Iran. Decision-Making Trial and Evaluation Laboratory (DEMATEL) are employed to reflect the interdependencies among BSC perspectives. Then, Analytic Network Process (ANP) is utilized to weight the indices influencing the considered problem. In the next step, we apply four MCDM methods including Additive Ratio Assessment (ARAS), Complex Proportional Assessment (COPRAS), Multi-Objective Optimization by Ratio Analysis (MOORA), and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) for ranking of alternatives. Finally, the utility interval technique is applied to combine the ranking results of MCDM methods. Weighted utility intervals are computed by constructing a correlation matrix between the ranking methods. A real case is presented to show the efficacy of the proposed approach.

    Common interventions for smoking cessation are based on medical advice and pharmacological aid. Information and communication technologies may be helpful as interventions by themselves or as complementary tools to quit smoking. The objective of the study was to determine the use of information and communication technologies (ICTs) in the smoking population attended in primary care, and describe the major factors associated with its use. Descriptive observational study in 84 health centres in Cataluña, Aragon and Salamanca. We included by simple random sampling 1725 primary healthcare smokers (any amount of tobacco) aged 18-85. Through personal interview professionals collected Socio-demographic data and variables related with tobacco consumption and ICTs use were collected through face to face interviews Factors associated with the use of ICTs were analyzed by logistic regression. Users of at least one ICT were predominantly male, young (18-45 years), from most favoured social classes and of higher education. Compared with non-ICTs users, users declared lower consumption of tobacco, younger onset age, and lower nicotine dependence. The percentages of use of email, text messages and web pages were 65.3%, 74.0% and 71.5%, respectively. Factors associated with the use of ICTs were age, social class, educational level and nicotine dependence level. The factor most closely associated with the use of all three ICTs was age; mainly individuals aged 18-24. The use of ICTs to quit smoking is promising, with the technology of mobile phones having a broader potential. Younger and more educated subjects are good targets for ICTs interventions on smoking cessation.

  18. Coproduction as an Approach to Technology-Mediated Citizen Participation in Emergency Management

    Directory of Open Access Journals (Sweden)

    Paloma Díaz

    2016-08-01

    Full Text Available Social and mobile computing open up new possibilities for integrating citizens’ information, knowledge, and social capital in emergency management (EM. This participation can improve the capacity of local agencies to respond to unexpected events by involving citizens not only as first line informants, but also as first responders. This participation could contribute to build resilient communities aware of the risks they are threatened by and able to mobilize their social capital to cope with them and, in turn, decrease the impact of threats and hazards. However for this participation to be possible organizations in charge of EM need to realize that involving citizens does not interfere with their protocols and that citizens are a valuable asset that can contribute to the EM process with specific skills and capabilities. In this paper we discuss the design challenges of using social and mobile computing to move to a more participatory EM process that starts by empowering both citizens and organizations in a coproduction service envisioned as a partnership effort. As an example, we describe a case study of a participatory design approach that involved professional EM workers and decision makers in an effort to understand the challenges of using technology-based solutions to integrate citizen skills and capabilities in their operation protocols. The case study made it possible to identify specific roles that citizens might play in a crisis or disaster and to envision scenarios were technologies could be used to integrate their skills into the EM process. In this way the paper contributes to the roles and the scenarios of theory-building about coproduction in EM services.

  19. An innovation management approach for renewable energy deployment. The case of solar photovoltaic (PV) technology

    2009-01-01

    In the discussion of renewable energy deployment, one key concern is the various types of barriers that renewable energy needs to overcome before it can make its way into the mainstream. These barriers increasingly shift from the technical to the economic and institutional. The most general types of barriers are due to technological 'lock-out' or to carbon 'lock-in' [. Understanding carbon lock-in. Energy Policy 28(12), 817-830 (Elsevier)]. These barriers necessitate the development of a strategic approach to deploy or introduce renewable energy technology. Existing energy policy has mostly relied upon financial subsidies, market-based instruments such as renewable portfolio standards, and production tax credits to stimulate the installation and use of equipment to generate electricity from renewable sources. These strategies target mostly system-level decisions of end users. The purpose of this paper is to present an innovation perspective on the renewable energy deployment process by introducing the innovation value-added chain (IVC) framework. The analytical objective of IVC is to evaluate the impact of a new innovation on the various stakeholders and players in the development and deployment processes. A deployment or innovation strategy that causes minimal disruption, enhances existing competencies, or expedites new learning by the players has a higher chance to succeed. We draw upon two sets of system integration costs data for grid-connected distributed photovoltaic (PV) systems in Japan and the United States and demonstrate conspicuously different dynamic learning behaviors. These two deployment models can be understood in terms of how the IVCs are organized and how PV system integration projects are performed in the field. In addition, IVC-based findings can inform the targeted application of conventional financial subsidies for learning investment not only at the PV system level, but also at the (localized) system integration level. This would involve

    2016-01-01

    Full Text Available It seems logical to argue that mobile computing technologies are intended for use "on-the-go." However, on closer inspection, the use of mobile technologies pose a number of challenges for users who are mobile, particularly moving around on foot. In engaging with such mobile technologies and their envisaged development, we argue that interaction designers must increasingly consider a multitude of perspectives that relate to walking in order to frame design problems appropriately. In this paper, we consider a number of perspectives on walking, and we discuss how these may inspire the design of mobile technologies. Drawing on insights from non-representational theory, we develop a partial vocabulary with which to engage with qualities of pedestrian mobility, and we outline how taking more mindful approaches to walking may enrich and inform the design space of handheld technologies

    Carrio, Miguel A., Jr.

    1988-01-01

    Rapidly emerging technology and methodologies have out-paced the systems development processes' ability to use them effectively, if at all. At the same time, the tools used to build systems are becoming obsolescent themselves as a consequence of the same technology lag that plagues systems development. The net result is that systems development activities have not been able to take advantage of available technology and have become equally dependent on aging and ineffective computer-aided engineering tools. New methods and tools approaches are essential if the demands of non-stop and Mission and Safety Critical (MASC) components are to be met.

    Silver, L D; Castilho, S R

    1998-12-01

    A consumer-protection assessment and action program aimed at improving reproductive health technologies is reviewed. Evaluations employed both literature review, synthesis, market analysis and laboratory testing for conformity to standards of a wide range of products which affect reproductive health on the Brazilian market 1995-1997. Anti-infective gynecological products, ampicillins, condoms, pregnancy tests, hormonal contraceptives, infant formulas, selected teratogens, bromocriptine and prostaglandins were studied. Actions include dissemination in periodicals and the mass media, consumer education, pressure for regulation, negotiations with manufacturers and legal action. The program was effective in improving the supply and regulation of some, but not all products studied. Impact on health and utilization are unknown. A significant proportion of products studied are unsafe, ineffective or of sub-standard quality. A combination of careful scientific work, strong links between scientists and social movements, dissemination and legal action, can effectively improve the quality of products which affect reproductive health.

    Well-child visits are a critical opportunity to promote learning and development, encourage positive parenting practices, help children acquire behavioral self-control, enhance the development and well-being of children and their families, identify problems not amenable to brief in-office counseling, and refer for services when needed. This article outlines the communication skills, instructional methods, and resource options that enable clinicians to best assist families. Also covered is how to monitor progress and outcomes. A total of 239 articles and 52 Web sites on parent/patient education were reviewed for this study. Providers require a veritable armamentarium of instructional methods. Skills in nonverbal and verbal communication are needed to elicit the parent/patient agenda, winnow topics to a manageable subset, and create the "teachable moment." Verbal suggestions, with or without standardized spoken instructions, are useful for conveying simple messages. However, for complex issues, such as discipline, it is necessary to use a combination of verbal advice, written information, and "teach-back," aided by role-playing/modeling or multimedia approaches. Selecting the approaches most likely to be effective depends on the topic and family characteristics (eg, parental literacy and language skills, family psychosocial risk and resilience factors, children's developmental-behavioral status). When providers collaborate well (with parents, patients, and other service providers) and select appropriate educational methods, families are better able to act on advice, leading to improvements in children's well-being, health, and developmental-behavioral outcomes. Provided are descriptions of methods, links to parenting resources such as cell phone applications, Web sites (in multiple languages), interactive technology, and parent training courses.

  8. Factors That Influence Renewable Energy Technological Innovation in China: A Dynamic Panel Approach

    Directory of Open Access Journals (Sweden)

    Zheng-Xia He

    2018-01-01

    Full Text Available We examine the driving effects of various factors on technological innovation to renewables (TIRES, focusing on a set of 29 provinces in China, and apply a dynamic panel approach. China has become a leading player in research and development spending in renewables, and the dynamic panel estimators we use prove themselves to be suitable in handling the persistent effect on TIRES. The level of TIRES in the previous periods is positively and highly correlated with that in the current period and confirmed the need for a stable and consistent policy support for renewables. Electricity consumption is the most important driver for all renewables and wind energy, but the driving effect was weaker for solar energy and biomass. Research and development intensity is the most important driver for biomass, but is only the second most important driver for all renewables, solar energy and wind energy. Unexpectedly, electricity price has had significant negative impacts on TIRES, which reveals that lowering electricity prices will lead to higher innovation in renewables. The driving effect of renewable energy tariff surcharge subsidy is not significant, which means that Chinese subsidy policy has not played the desired role. The driving effect of installed renewable energy capacity is also minimal, which may be due to the fact that overcapacity will hinder TIRES in China. This paper may help policy-makers and the industry understand how to promote TIRES in China effectively based on these above influential factors.

    2014-08-01

    Full Text Available The European workplace is challenging VET adults’ problem-solving skills in technology-rich environments (TREs. So far, no international large-scale assessment data has been available for VET. The PIAAC data comprise the most comprehensive source of information on adults’ skills to date. The present study (N=50 369 focuses on gaining insight into the problem-solving skills in TREs of adults with a VET background. When examining the similarities and differences in VET adults’ problem-solving skills in TREs across 11 European countries, two main trends can be observed. First, our results show that only a minority of VET adults perform at a high level. Second, there seems to be substantial variation between countries with respect to the proportion of VET adults that can be identified as “at-risk” or “weak” performers. For the future, our findings indicate the variations that can be used as a starting point to identify beneficial VET approaches.

    1999-08-01

    As the semiconductor roadmap continues to require imaging of smaller features on wafers, we continue to explore new approaches in OPC strategies to enhance existing technology. Advanced reticle design, intended for printing sub-wavelength features, requires the support of very fine-increment biases on semi-densely-pitched lines, where the CD correction requires only a fraction of the spot size of an e-beam system. Halftone biasing, a new OPC strategy, has been proposed to support these biases on a raster-scan e-beam system without the need for a reduced address unit and the consequent write time penalty. The manufacturability and inspectability of halftone-biased lines are explored, using an OPC characterization reticle. Pattern fidelity is examined using both optical and SEM tools. Printed DUV resist line edge profiles are compared for both halftone and non-halftone feature edges. Halftone biasing was applied to an SRAM-type simulation reticle, to examine its impact on data volume, write time reduction, and printing performance.

  7. A consortium approach to commercialized Westinghouse solid oxide fuel cell technology

    Science.gov (United States)

    Casanova, Allan

    Westinghouse is developing its tubular solid oxide fuel cells (SOFCs) for a variety of applications in stationary power generation markets. By pressurizing a SOFC and integrating it with a gas turbine (GT), power systems with efficiencies as high as 70-75% can be obtained. The first such system will be tested in 1998. Because of their extraordinarily high efficiency (60-70%) even in small sizes the first SOFC products to be offered are expected to be integrated SOFC/GT power systems in the 1-7 MW range, for use in the emerging distributed generation (DG) market segment. Expansion into larger sizes will follow later. Because of their modularity, environmental friendliness and expected cost effectiveness, and because of a worldwide thrust towards utility deregulation, a ready market is forecasted for baseload distributed generation. Assuming Westinghouse can complete its technology development and reach its cost targets, the integrated SOFC/GT power system is seen as a product with tremendous potential in the emerging distributed generation market. While Westinghouse has been a leader in the development of power generation technology for over a century, it does not plan to manufacture small gas turbines. However, GTs small enough to integrate with SOFCs and address the 1-7 MW market are generally available from various manufacturers. Westinghouse will need access to a new set of customers as it brings baseload plants to the present small market mix of emergency and peaking power applications. Small cogeneration applications, already strong in some parts of the world, are also gaining ground everywhere. Small GT manufacturers already serve this market, and alliances and partnerships can enhance SOFC commercialization. Utilities also serve the DG market, especially those that have set up energy service companies and seek to grow beyond the legal and geographical confines of their current regulated business. Because fuel cells in general are a new product, because small

    Intensive arable food production systems are in need of smart solutions that combine ecological knowledge and farm technology to maximize yields while protecting natural resources. The huge diversity of soil organisms and their interactions is of crucial importance for soil functions and ecosystem services, such as organic matter incorporation and break down, nutrient mineralization, soil structure formation, water regulation and disease and pest control. Soil management decisions that take into account the soil biodiversity and associated functions are thus essential to (i) maintain soil productivity in the long term, (ii) reduce the dependency on external inputs and non-renewables such as fossil fuels, and (iii) make agroecosystems more resilient against biotic and abiotic stresses. Organic farming systems and reduced tillage systems are two approaches that aim to increase soil biodiversity and general soil quality, through improved management of organic matter but differ in their emphasis on the use of chemical inputs for crop protection or soil disturbance, respectively. In North-western Europe experience with and knowledge of reduced tillage systems is still scarce, both in conventional and organic farming. Our study targeted both conventional and organic farming and aimed at 1) documenting reduced tillage practices within different agroecological contexts in NW Europe; 2) evaluating the effects of reduced tillage systems on soil biodiversity and soil ecosystem services; 3) increase understanding of agroecological factors that determine trade-offs between different ecosystem services. Earthworm species and nematode taxa were selected as indicator organisms to be studied for their known response to soil management and effects on soil functions. Additionally, soil organic matter, physical soil parameters and processes, and crop yields have been measured across multiple sites. Data have been collected over several cropping seasons in long term field experiments

    2009-01-01

    As a provider of national energy security, the Korean Institute of Energy Research is seeking to establish a long term strategic technology roadmap for a hydrogen-based economy. This paper addressed 5 criteria regarding the strategy, notably economic impact, commercial potential, inner capacity, technical spinoff, and development cost. The fuzzy AHP and DEA hybrid model were used in a two-stage multi-criteria decision making approach to evaluate the relative efficiency of hydrogen technologies for the hydrogen economy. The fuzzy analytic hierarchy process reflects the uncertainty of human thoughts with interval values instead of clear-cut numbers. It therefore allocates the relative importance of 4 criteria, notably economic impact, commercial potential, inner capacity and technical spin-off. The relative efficiency of hydrogen technologies for the hydrogen economy can be measured via data envelopment analysis. It was concluded that the scientific decision making approach can be used effectively to allocate research and development resources and activities

    Risk-based approach is used for examination of impact of different factors on quality of medicinal products in technology transfer. A general diagram is offered for risk analysis execution in technology transfer from pharmaceutical development to production. When transferring technology to full- scale commercial production it is necessary to investigate and simulate production process application beforehand in new real conditions. The manufacturing process is the core factorfor risk analysis having the most impact on quality attributes of a medicinal product. Further importantfactors are linked to materials and products to be handled and manufacturing environmental conditions such as premises, equipment and personnel. Usage of risk-based approach in designing of multipurpose production facility of medicinal products is shown where quantitative risk analysis tool RAMM (Risk Analysis and Mitigation Matrix) was applied.

    Diabetes and its related complications and comorbidities (C&Cs) represent a significant and increasing healthcare burden. Absence of a systematic manner to evaluate value propositions of technologies from various stakeholders' perspectives impedes the best uses of current and emerging technologies. A system dynamics methodology was used to develop a comprehensive causal simulator of the U.S. population and give proof of principle that entire portfolios of present and future technologies can be evaluated for direct and indirect impacts. An explicit semiquantitative methodology was used for surveying, prioritizing, and grouping C&Cs, patient subgroups, and technologies, utilizing diverse publicly available clinical literature. The resulting model simulates the incidence and prevalence of diabetes and 10 of its most commonly associated C&Cs, reflecting their interrelated upstream and downstream relationships. The simulator enables systematic evaluation of tens of thousands of potential combinations of emerging technologies and technology leverage points that can be used to improve patient outcomes and guide technology investments. Feasibility was demonstrated through single, pair-wise, and targeted analyses of technologies. This effort demonstrated the feasibility of linking complex, interconnected disease states, impact points, outcomes, and interventions with a variety of outcome metrics, to an extent greater than existing models developed for other purposes. The project demonstrated the ability to identify priority technologies and pipeline therapies and leverage points among diabetes interventions. It demonstrated more effective knowledge management of diverse information essential for formulating strategy that could be applied in a wide range of therapeutic applications and technology innovation uses.

  13. Patterns of technological innovation and evolution in the energy sector: A patent-based approach

    Lee, Kyungpyo; Lee, Sungjoo

    2013-01-01

    Given the ever-increasing pace and complexity of technological innovation in the energy sector, monitoring technological changes has become of strategic importance. One of the most common techniques for technology monitoring is patent analysis, which enables the identification of technological trends over time. However, few previous studies have carried out patent analysis in the energy sector. This study aims to explore patterns of innovation and of evolution in energy technologies, particularly focusing on similarities and differences across technologies. For this purpose, we first defined the relevant energy technologies and extracted the associated patent data from the United States Patents and Trademark Office (USPTO) and then adopted six patent indices and developed six patent maps to analyze their innovation characteristics. We then clustered energy technologies with similar characteristics, so defining innovation categories, and analyzed the changes in these characteristics over time to define their evolution categories. As one of the few attempts to investigate the overall trends in the energy sector's innovation and evolution, this study is expected to help develop an in-depth understanding of the energy industry, which will be useful in establishing technology strategies and policy in this rapidly changing sector. - Highlights: • We examined the patterns of innovation and evolution of energy technologies. • Six types of innovation patterns such as “competitive” or “mature” were identified. • Six types of evolution patterns such as “towards closed innovation” were identified. • The patterns of evolution were related to the patterns of innovation

    The development of non-animal testing methods for the assessment of skin sensitisation potential is an urgent challenge within the framework of existing and forthcoming legislation. Efforts have been made to replace current animal tests, but so far no alternative methods have been developed. It is widely recognised that alternatives to animal testing cannot be accomplished with a single approach, but rather will require the integration of results obtained from different in vitro and in silico assays. The argument subjacent to the development of in vitro dendritic cell (DC)-based assays is that sensitiser-induced changes in the DC phenotype can be differentiated from those induced by irritants. This assumption is derived from the unique capacity of DC to convert environmental signals encountered at the skin into a receptor expression pattern (MHC class II molecules, co-stimulatory molecules, chemokine receptors) and a soluble mediator release profile that will stimulate T lymphocytes. Since signal transduction cascades precede changes in surface marker expression and cytokine/chemokine secretion, these phenotypic modifications are a consequence of a signal transduction profile that is specifically triggered by sensitisers and not by irritants. A limited number of studies have addressed this subject and the present review attempts to summarise and highlight all of the signalling pathways modulated by skin sensitisers and irritants. Furthermore, we conclude this review by focusing on the most promising strategies suitable for inclusion into a cell-based in vitro alternative approach to hazard identification.

    One of the major and less explored issues in the characterization of historical glasses is the determination of their viscosity as a function of temperature in order to constrain technological aspects of glass production. Until now, assumptions on temperatures have been based on mathematical models based on chemical compositions. Hence, the topic of this work is to explore the technology of stained glass production related to the workability and melting process of the glass by experimental laboratory measurements. This work presents the analysis of viscosity of glasses from different historical sites and chemical compositions: four from Santes Creus (Tarragona, XIII century), two of classical medieval stained glass window from Santa Maria de Pedralbes (Barcelona, mid XIV century), and three of evolved late-medieval type from Santa Maria del Mar (Barcelona first half of XV century), and one sample of soda-lime industrial glass by means of Hot-Stage Microscopy and glass transformation temperature Tg by dilatometry. These data are then compared to the predictions on theoretical viscosity obtained from mathematical models based on chemical composition. These samples are classified according to their major modifier in: Na-rich (12-17% of Na2O, between 65-77% of SiO2 and less than 3 % of K2O); Ca-rich (29% of CaO, 54% of SiO2, 4% of K2O, and 4% of Na2O); K-Ca-rich (17 to 21% of K2O, more than 14% of CaO, 49-55% of SiO2and less than 2% of Na2O); Na-Ca-rich (12-14% of Na2O, 9-15% of CaO, 57-71% of SiO2 and process (melting, working, conditioning and annealing ranges). These results are also compared to mathematical models of glass viscosity based on chemical composition. The annealing range (viscosity between 1013.5 and 1012 Pa-s) is reached at temperatures between 484-633°C (strain point) and 509-664°C (upper limit). The working point (viscosity of 103 Pa-s) has temperature values in the range between 958 and 1097°C.

    Full Text Available The rapid growth of the use of new technologies is having an important effect on individuals’ health knowledge and behavior. The objective of this paper is to study the potential reduction in health care utilization associated with the expansion of new technologies. Using Spanish micro data from the Survey on the Equipment and Use of Information and Communication Technologies (ICT-H in Households for 2014 we analyze information technologies equipment, availability of access and means of Internet connection per household. We model the probability of an individual being internet user in Spain as a function of a range of socio-economic characteristics, including individual’s gender, age, education and employment situation. Also, we hypothesized that a greater use of this communication technologies is related to a lesser health care expenditure.

  19. A cautionary approach in transitioning to 'green' energy technologies and practices is required.

    Matatiele, Puleng; Gulumian, Mary

    2016-06-01

    Renewable energy technologies (wind turbines, solar cells, biofuels, etc.) are often referred to as 'clean' or 'green' energy sources, while jobs linked to the field of environmental protection and energy efficiency are referred to as 'green' jobs. The energy efficiency of clean technologies, which is likely to reduce and/or eliminate reliance on fossil fuels, is acknowledged. However, the potential contribution of green technologies and associated practices to ill health and environmental pollution resulting from consumption of energy and raw materials, generation of waste, and the negative impacts related to some life cycle phases of these technologies are discussed. Similarly, a point is made that the green jobs theme is mistakenly oversold because the employment opportunities generated by transitioning to green technologies are not necessarily safe and healthy jobs. Emphasis is put on identifying the hazards associated with these green designs, assessing the risks to the environment and worker health and safety, and either eliminating the hazards or minimizing the risks as essential elements to the design, construction, operation, and maintenance of green technologies. The perception that it is not always economically possible to consider all risk factors associated with renewable energy technologies at the beginning without hampering their implementation, especially in the poor developing countries, is dismissed. Instead, poor countries are encouraged to start implementing environmentally sound practices while transitioning to green technologies in line with their technological development and overall economic growth.

    Full Text Available Teaching in a Teacher centric manner has been the mainframe teaching style in engineering education, however students feel it as a single sided approach and feel they are only passive listeners thus this style has now paved way to a Learner centric style of teaching-learning which is ACTIVE LEARNING, wherein every student is actively involved in one or the other form of learning and thus gets a chance to develop the key aspects of the course either on their own or by being a member of an active-learning group. They thus not only learn and practice the course contents but also learn managerial and team skills which are of much importance in present scenario in regard to Industries and companies where these students will be ultimately hired as employees. Professional education is making one’s students ready for the profession which includes team work, management and technical skills, thus Active learning has emerged as a mainframe tool for cherishing this aim of professional education, especially Science, Technology, Engineering and Management (STEM education. This paper aims to focus on a few facets of this active learning process and give an overview to the teaching faculty as well as students on what their individual roles must be like in this process for getting the most out of this process.

    2017-01-01

    Improved knowledge about plant cold stress tolerance offered by modern omics technologies will greatly inform future crop improvement strategies that aim to breed cultivars yielding substantially high under low-temperature conditions. Alarmingly rising temperature extremities present a substantial impediment to the projected target of 70% more food production by 2050. Low-temperature (LT) stress severely constrains crop production worldwide, thereby demanding an urgent yet sustainable solution. Considerable research progress has been achieved on this front. Here, we review the crucial cellular and metabolic alterations in plants that follow LT stress along with the signal transduction and the regulatory network describing the plant cold tolerance. The significance of plant genetic resources to expand the genetic base of breeding programmes with regard to cold tolerance is highlighted. Also, the genetic architecture of cold tolerance trait as elucidated by conventional QTL mapping and genome-wide association mapping is described. Further, global expression profiling techniques including RNA-Seq along with diverse omics platforms are briefly discussed to better understand the underlying mechanism and prioritize the candidate gene (s) for downstream applications. These latest additions to breeders' toolbox hold immense potential to support plant breeding schemes that seek development of LT-tolerant cultivars. High-yielding cultivars endowed with greater cold tolerance are urgently required to sustain the crop yield under conditions severely challenged by low-temperature.

  4. A new approach to standardize multicenter studies: mobile lab technology for the German Environmental Specimen Bank.

    Dominik Lermen

    Full Text Available Technical progress has simplified tasks in lab diagnosis and improved quality of test results. Errors occurring during the pre-analytical phase have more negative impact on the quality of test results than errors encountered during the total analytical process. Different infrastructures of sampling sites can highly influence the quality of samples and therewith of analytical results. Annually the German Environmental Specimen Bank (ESB collects, characterizes, and stores blood, plasma, and urine samples of 120-150 volunteers each on four different sampling sites in Germany. Overarching goal is to investigate the exposure to environmental pollutants of non-occupational exposed young adults combining human biomonitoring with questionnaire data. We investigated the requirements of the study and the possibility to realize a highly standardized sampling procedure on a mobile platform in order to increase the required quality of the pre-analytical phase. The results lead to the development of a mobile epidemiologic laboratory (epiLab in the project "Labor der Zukunft" (future's lab technology. This laboratory includes a 14.7 m(2 reception area to record medical history and exposure-relevant behavior, a 21.1 m(2 examination room to record dental fillings and for blood withdrawal, a 15.5 m(2 biological safety level 2 laboratory to process and analyze samples on site including a 2.8 m(2 personnel lock and a 3.6 m2 cryofacility to immediately freeze samples. Frozen samples can be transferred to their final destination within the vehicle without breaking the cold chain. To our knowledge, we herewith describe for the first time the implementation of a biological safety laboratory (BSL 2 lab and an epidemiologic unit on a single mobile platform. Since 2013 we have been collecting up to 15.000 individual human samples annually under highly standardized conditions using the mobile laboratory.

    As part of its mandate, the CTBTO's nuclear explosion monitoring programme aims to maintain its sustainability, effectiveness and its long-term relevance to the verification regime. As such, the PTS is conducting a Technology Foresight programme of activities to identify technologies, processes, concepts and ideas that may serve said purpose and become applicable within the next 20 years. Through the Technology Foresight activities (online conferences, interviews, surveys, workshops and other) we have involved the wider science community in the fields of seismology, infrasound, hydroacoustics, radionuclide technology, remote sensing and geophysical techniques. We have assembled a catalogue of over 200 items, which incorporate technologies, processes, concepts and ideas which will have direct future relevance to the IMS (International Monitoring System), IDC (International Data Centre) and OSI (On-Site Inspection) activities within the PTS. In order to render this catalogue as applicable and useful as possible for strategy and planning, we have devised a "taxonomy" based on seven categories, against which each technology is assessed through a peer-review mechanism. These categories are: 1. Focus area of the technology in question: identify whether the technology relates to (one or more of the following) improving our understanding of source and source physics; propagation modelling; data acquisition; data transport; data processing; broad modelling concepts; quality assurance and data storage. 2. Current Development Stage of the technology in question. Based on a scale from one to six, this measure is specific to PTS needs and broadly reflects Technology Readiness Levels (TRLs). 3. Impact of the technology on each of the following capabilities: detection, location, characterization, sustainment and confidence building. 4. Development cost: the anticipated monetary cost of validating a prototype (i.e. Development Stage 3) of the technology in question. 5. Time to

    The paper recapitulates some key elements in previously published results concerning exact and complete reconstitution of the field of natural numbers, both as ordinal and as cardinal numbers, from systematic unfoldment of the Fibonacci algorithm. By this natural numbers emerge as Fibonacci 'atoms' and 'molecules' consistent with the notion of Zeckendorf sums. Here, the sub-set of prime numbers appears not as the primary numbers, but as an epistructure from a deeper Fibonacci constitution, and is thus targeted from a 'positive approach'. In the Fibonacci reconstitution of number theory natural numbers show a double geometrical aspect: partly as extension in space and partly as position in a successive structuring of space. More specifically, the natural numbers are shown to be distributed by a concise 5:3 code structured from the Fibonacci algorithm via Pascal's triangle. The paper discusses possible implications for the more general relation between number theory and geometry, as well as more specifically in relation to hadronic mathematics, initiated by R.M. Santilli, and also briefly to some other recent science linking number theory more directly to geometry and natural systems

    Full Text Available The aim of this paper is to evaluate the stage of Information Technology implementation in the agricultural farms in Romania. At the level of each Romanian development region it was performed a research for identifying the use of Information Technology. In addition, it was conducted a study on the management applied in the agricultural farms, the market of information solutions developed for farms specific needs and of the politics that promote the investments in the Information Technology. The research had as result the identification of the main factors that lead to a reduced Information Technology penetration rate in the Romanian agriculture such as: the reduced number of agricultural farms with legal personality, the decreased investment potential of agricultural farms, the lack of interest of software developer enterprises in providing Farm Management Information Systems and the poor professional skills of farm managers and their employees in the Information Technology field.

  18. Analysis of the impact of climate change on groundwater related hydrological fluxes: a multi-model approach including different downscaling methods

    2011-01-01

    Full Text Available Climate change related modifications in the spatio-temporal distribution of precipitation and evapotranspiration will have an impact on groundwater resources. This study presents a modelling approach exploiting the advantages of integrated hydrological modelling and a broad climate model basis. We applied the integrated MIKE SHE model on a perialpine, small catchment in northern Switzerland near Zurich. To examine the impact of climate change we forced the hydrological model with data from eight GCM-RCM combinations showing systematic biases which are corrected by three different statistical downscaling methods, not only for precipitation but also for the variables that govern potential evapotranspiration. The downscaling methods are evaluated in a split sample test and the sensitivity of the downscaling procedure on the hydrological fluxes is analyzed. The RCMs resulted in very different projections of potential evapotranspiration and, especially, precipitation. All three downscaling methods reduced the differences between the predictions of the RCMs and all corrected predictions showed no future groundwater stress which can be related to an expected increase in precipitation during winter. It turned out that especially the timing of the precipitation and thus recharge is very important for the future development of the groundwater levels. However, the simulation experiments revealed the weaknesses of the downscaling methods which directly influence the predicted hydrological fluxes, and thus also the predicted groundwater levels. The downscaling process is identified as an important source of uncertainty in hydrological impact studies, which has to be accounted for. Therefore it is strongly recommended to test different downscaling methods by using verification data before applying them to climate model data.

  19. A Process Analytical Technology (PAT) approach to control a new API manufacturing process: development, validation and implementation.

    2014-03-01

    Pharmaceutical companies are progressively adopting and introducing Process Analytical Technology (PAT) and Quality-by-Design (QbD) concepts promoted by the regulatory agencies, aiming the building of the quality directly into the product by combining thorough scientific understanding and quality risk management. An analytical method based on near infrared (NIR) spectroscopy was developed as a PAT tool to control on-line an API (active pharmaceutical ingredient) manufacturing crystallization step during which the API and residual solvent contents need to be precisely determined to reach the predefined seeding point. An original methodology based on the QbD principles was designed to conduct the development and validation of the NIR method and to ensure that it is fitted for its intended use. On this basis, Partial least squares (PLS) models were developed and optimized using chemometrics methods. The method was fully validated according to the ICH Q2(R1) guideline and using the accuracy profile approach. The dosing ranges were evaluated to 9.0-12.0% w/w for the API and 0.18-1.50% w/w for the residual methanol. As by nature the variability of the sampling method and the reference method are included in the variability obtained for the NIR method during the validation phase, a real-time process monitoring exercise was performed to prove its fit for purpose. The implementation of this in-process control (IPC) method on the industrial plant from the launch of the new API synthesis process will enable automatic control of the final crystallization step in order to ensure a predefined quality level of the API. In addition, several valuable benefits are expected including reduction of the process time, suppression of a rather difficult sampling and tedious off-line analyses. © 2013 Published by Elsevier B.V.

  20. IN SITU GEOTHERMAL ENERGY TECHNOLOGY: AN APPROACH FOR BUILDING CLEANER AND GREENER ENVIRONMENT

    Full Text Available Geothermal energy is abundant everywhere in the world. It certainly would be a great benefit for human being once it is produced by a sophisticated technology. Consequently, it would be the biggest console for earth considering environmental sustainability. Unfortunately, the current status of commercial production of geothermal energy primarily from hydrothermal, geopressured, hot dry rock, and magma are limited to a few countries due to technological difficulties and production cost. This paper describes a simple technology where an in situ geothermal plant assisted by a heat pump would act as a high-temperature production (>150°C to provide excellent capacity of energy generation. The issue related to costs is interestingly cheaper on production, comparing to other technologies, such as solar, hydro, wind, and traditional geothermal technology as described in this article. Therefore, it is suggested that heat pump assisted in situ geothermal energy sources has a great potentiality to be a prime energy source in near future. Since the technology has a number of positive characteristics (simple, safe, and provides continuous baseload, load following, or peaking capacity and benign environmental attributes (zero emissions of CO2, SOx, and NOx, it certainly would be an interesting technology in both developed, and developing countries as an attractive option to produce clean energy to confirm a better environment.

  2. Going 3D with Technology: An Overarching Approach for Language Teachers

    Directory of Open Access Journals (Sweden)

    Jason D. Hendryx

    2016-05-01

    Grounded in over a decade of language classroom observations, in multiple institutions of secondary and higher education in several countries, across over a dozen languages, three key features of what appear to be successful applications of technology by instructors in these classes for language teaching emerged. These features came to be identified as directional, developmental, and decisive—Hereafter referred to as the 3Ds. Observational data suggests that when an instructor embraces any of the 3Ds while using technology for teaching and learning purposes, the more successful that application of technology seems to be. Success here should be understood as higher levels of student interaction, engagement, and motivation, with more kinds and types of student language being produced.  Meanwhile, observations of instructors who did not utilize any of the 3Ds, revealed stiff, uninspiring uses of technology, oftentimes devoid of context, which did not result in much, if any, student interaction or language production.

    Highlights: • Grid effects of intermittent sources show increasing need for decentralized storage. • Novel patent classification is applied to monitor competing technologies. • Up-to-date geographical, organizational, and qualitative insight is given. • Redox flow patenting shows strong growth, lithium also strong absolute numbers. • Revealed patents allow the expectation of improved modules in the future. - Abstract: Due to the suitability to balance the intermittency in decentralized systems with renewable sources, electrochemical energy storage possibilities have been analyzed in several studies, all highlighting the need for improvements in relevant techno-economic parameters. Particularly a reduction in the costs per cycle is much needed, which could either come from innovation in more cost-efficient manufacturing methods, a higher endurance of charge/discharge sequences or higher capacities. Looking at patent applications as a metric allows us to determine whether the necessary technological progress is indeed occurring, as the mandatory publication of the underlying inventions provides access to otherwise hidden R and D activities. Our paper contributes to the literature with a compilation of technological classes related to important battery types in the novel Cooperative Patent Classification (CPC), which can be used to identify relevant patent applications of the competing technologies. Using the worldwide patent statistical database (PATSTAT), we find that promising technologies have been showing increasing patent counts in recent years. For example, the number of patent applications related to regenerative fuel cells (e.g. redox flow batteries) doubled from 2009 to 2011. Nevertheless, the volume of patent filings in technologies related to lithium remains unchallenged. Patent applications in this area are still growing, which indicates that the introduction of improved modules will continue. Using citation analysis, we have identified

    2015-05-01

    The aim of this study was to develop and psychometrically test a shortened version of the Information Technology Attitude Scales for Health, in the investigation of nursing students with clinical placement experiences. Nurses and nursing students need to develop high levels of competency in information and communication technology. However, they encounter statistically significant barriers in the use of the technology. Although some instruments have been developed to measure factors that influence nurses' attitudes towards technology, the validity is questionable and few studies have been developed to test the attitudes of nursing students, in particular. A cross-sectional survey design was performed. The Information Technology Attitude Scales for Health was used to collect data from October 2012-December 2012. A panel of experts reviewed the content of the instrument and a pilot study was conducted. Following this, a total of 508 nursing students, who were engaged in clinical placements, were recruited from six universities in South Korea. Exploratory and confirmatory factor analyses were performed and reliability and construct validity were assessed. The resulting instrument consisted of 19 items across four factors. Reliability of the four factors was acceptable and the validity was supported. The instrument was shown to be both valid and reliable for measuring nursing students' attitudes towards technology, thus aiding in the current understandings of this aspect. Through these measurements and understandings, nursing educators and students are able to be more reflexive of their attitudes and can thus seek to develop them positively. © 2015 John Wiley & Sons Ltd.

    2011-01-01

    Standalone levelised cost assessments of electricity supply options miss an important contribution that renewable and non-fossil fuel technologies can make to the electricity portfolio: that of reducing the variability of electricity costs, and their potentially damaging impact upon economic activity. Portfolio theory applications to the electricity generation mix have shown that renewable technologies, their costs being largely uncorrelated with non-renewable technologies, can offer such benefits. We look at the existing Scottish generation mix and examine drivers of changes out to 2020. We assess recent scenarios for the Scottish generation mix in 2020 against mean-variance efficient portfolios of electricity-generating technologies. Each of the scenarios studied implies a portfolio cost of electricity that is between 22% and 38% higher than the portfolio cost of electricity in 2007. These scenarios prove to be mean-variance 'inefficient' in the sense that, for example, lower variance portfolios can be obtained without increasing portfolio costs, typically by expanding the share of renewables. As part of extensive sensitivity analysis, we find that Wave and Tidal technologies can contribute to lower risk electricity portfolios, while not increasing portfolio cost. - Research Highlights: → Portfolio analysis of scenarios for Scotland's electricity generating mix in 2020. → Reveals potential inefficiencies of selecting mixes based on levelised cost alone. → Portfolio risk-reducing contribution of Wave and Tidal technologies assessed.

    Full Text Available In the current technological world of Information services, academic systems are also in the process of adapting information technology solutions. Information systems vary for different applications and specifically in academia domain, a range of information systems are available for different institutions worldwide. Integration of e-learning can optimize implementation of computer-based and computer-assisted educational processes at all levels. Therefore it is imperative to assess and evaluate integration of these information systems because they have serious impact on e-learning processes. In this study an instrument survey is presented for evaluating integration of information technology systems and practices in an educational environment. Survey is constructed using descriptive questions related to information technology tools to assess qualitative impact and usage of such tools. Critical feedback, analysis and suggestions from 25 educationists played a pivotal role in finalizing proposed survey questionnaire. A subsequent test evaluation by teachers and students is also carried out to assess adequate utilization of information systems in Yanbu University College. The results showed that feedback using this survey can help in identifying technological gaps and facilitate effective integration of information technology in an educational environment. Survey instrument proposed in this research can greatly enhance integration of IT tools as it can identify shortcomings by collecting statistical data from feedback of both faculty and students. Solution to these problems is deterministic and can be easily implemented to optimize overall performance of e-learning systems.

    In a 2-part study, we first examined the results of 71 surveyed physicians who provided responses on how they address the management of patients who maintained either a pacemaker or a defibrillator during radiation treatment. Second, a case review study is presented involving 112 medical records reviewed at 18 institutions to determine whether there was a change in the radiation prescription for the treatment of the target cancer, the method of radiation delivery, or the method of radiation image acquisition. Statistics are provided to illustrate the level of administrative policy; the level of communication between radiation oncologists and heart specialists; American Joint Committee on Cancer (AJCC) staging and classification; National Comprehensive Cancer Network (NCCN) guidelines; tumor site; patient׳s sex; patient׳s age; device type; manufacturer; live monitoring; and the reported decisions for planning, delivery, and imaging. This survey revealed that 37% of patient treatments were considered for some sort of change in this regard, whereas 59% of patients were treated without regard to these alternatives when available. Only 3% of all patients were identified with an observable change in the functionality of the device or patient status in comparison with 96% of patients with normal behavior and operating devices. Documented changes in the patient׳s medical record included 1 device exhibiting failure at 0.3-Gy dose, 1 device exhibiting increased sensor rate during dose delivery, 1 patient having an irregular heartbeat leading to device reprogramming, and 1 patient complained of twinging in the chest wall that resulted in a respiratory arrest. Although policies and procedures should directly involve the qualified medical physicist for technical supervision, their sufficient involvement was typically not requested by most respondents. No treatment options were denied to any patient based on AJCC staging, classification, or NCCN practice standards. Copyright

  19. Measuring energy efficiency under heterogeneous technologies using a latent class stochastic frontier approach: An application to Chinese energy economy

    International Nuclear Information System (INIS)

    Lin, Boqiang; Du, Kerui

    2014-01-01

    The importance of technology heterogeneity in estimating economy-wide energy efficiency has been emphasized by recent literature. Some studies use the metafrontier analysis approach to estimate energy efficiency. However, for such studies, some reliable priori information is needed to divide the sample observations properly, which causes a difficulty in unbiased estimation of energy efficiency. Moreover, separately estimating group-specific frontiers might lose some common information across different groups. In order to overcome these weaknesses, this paper introduces a latent class stochastic frontier approach to measure energy efficiency under heterogeneous technologies. An application of the proposed model to Chinese energy economy is presented. Results show that the overall energy efficiency of China's provinces is not high, with an average score of 0.632 during the period from 1997 to 2010. - Highlights: • We introduce a latent class stochastic frontier approach to measure energy efficiency. • Ignoring technological heterogeneity would cause biased estimates of energy efficiency. • An application of the proposed model to Chinese energy economy is presented. • There is still a long way for China to develop an energy efficient regime

    Science.gov (United States)

    Ellery, Alex; Richter, Lutz; Parnell, John; Baker, Adam

    2006-10-01

    We present a proposed robotic mission to Mars—Vanguard—for the Aurora Arrow programme which combines an extensive technology demonstrator with a high scientific return. The novel aspect of this technology demonstrator is the demonstration of “water mining” capabilities for in situ resource utilisation (ISRU) in conjunction with high-value astrobiological investigation within a low-mass lander package of 70 kg. The basic architecture comprises a small lander, a micro-rover and a number of ground-penetrating moles. This basic architecture offers the possibility of testing a wide variety of generic technologies associated with space systems and planetary exploration. The architecture provides for the demonstration of specific technologies associated with planetary surface exploration, and with the Aurora programme specifically. Technology demonstration of ISRU will be a necessary precursor to any future human mission to Mars. Furthermore, its modest mass overhead allows the re-use of the already built Mars Express bus, making it a very low-cost option.

    2016-10-06

    The US Department of Veterans Affairs (VA) has developed various health information technology (HIT) resources to provide accessible veteran-centered health care. Currently, the VA is undergoing a major reorganization of VA HIT to develop a fully integrated system to meet consumer needs. Although extensive system documentation exists for various VA HIT systems, a more centralized and integrated perspective with clear documentation is needed in order to support effective analysis, strategy, planning, and use. Such a tool would enable a novel view of what is currently available and support identifying and effectively capturing the consumer's vision for the future. The objective of this study was to develop the VA HIT Systems Matrix, a novel tool designed to describe the existing VA HIT system and identify consumers' vision for the future of an integrated VA HIT system. This study utilized an expert panel and veteran informant focus groups with self-administered surveys. The study employed participatory research methods to define the current system and understand how stakeholders and veterans envision the future of VA HIT and interface design (eg, look, feel, and function). Directed content analysis was used to analyze focus group data. The HIT Systems Matrix was developed with input from 47 veterans, an informal caregiver, and an expert panel to provide a descriptive inventory of existing and emerging VA HIT in four worksheets: (1) access and function, (2) benefits and barriers, (3) system preferences, and (4) tasks. Within each worksheet is a two-axis inventory. The VA's existing and emerging HIT platforms (eg, My HealtheVet, Mobile Health, VetLink Kiosks, Telehealth), My HealtheVet features (eg, Blue Button, secure messaging, appointment reminders, prescription refill, vet library, spotlight, vitals tracker), and non-VA platforms (eg, phone/mobile phone, texting, non-VA mobile apps, non-VA mobile electronic devices, non-VA websites) are organized by row.

    Full Text Available Teaching projects which make use of new technology are becoming of interest to all academic institutions in the UK due to economic pressure to increase student numbers. CMC (Computer- Mediated Communication such as computer conferencing appears an attractive solution to higher education's 'numbers' problem, with the added benefit that it is free from time and place constraints. Researchers have discussed CMC from a number of different perspectives, for example Mason and Kaye (1989 describe a CMC system as a system of interactivity between tutors, students, resources and organizational structure. Steeples et al (1993 consider CMC in terms of group cohesion, modes of discourse and intervention strategies to stimulate and structure participation. Goodyear et al (1994 discuss the Just in Time (TT-Based Open Learning (JTTOL model in terms of a set of educational beliefs, role definitions, working methods and learning resources, together with a definition of infrastructure requirements for CMC. Shedletsky (1993 suggests that a CMC should be viewed in terms of an 'intrapersonal communication' model, while Mayes et al (1994 identify three types of learning which is mediated by telematics, that is, learning by conceptualization, construction and dialogue. Other researchers, such as Velayo (1994, describe the teacher as 'an active agent', and present a model for computer conferencing which neglects the social aspect of CMC, while Berge (1995 mentions the importance of social activity between students and the importance of the role of the moderator. From these accounts, there appear to be a number of dimensions which can be used to evaluate CMC. Not all researchers emphasize the same dimensions; however, this paper proposes that computer conferencing systems should be designed to encourage students to participate in all three of the following dimensions. These can be summarized as: (a a knowledge dimension (includes domain and meta knowledge; (b a social

  5. A three pronged approach to community scale renewable energy: Education, incremental capital investment and smart grid technology

    Demeo, Anna E.

    The reality of global climate change, due to anthropogenic emissions of carbon dioxide and other gases, is upon us. A significant source of emissions comes from the burning of fossil fuels to produce energy that is consumed in every aspect of daily life. As such, the human ecological link between how we live and our impact on the planet is at the very center of addressing the causes of climate change. Reducing and eventually eliminating emissions is an enormous and complex task that will involve input and change from all corners of society. Therefore, reducing anthropogenic emissions and confronting the impacts of global climate change must be addressed across disciplines including education, community outreach and technology. A first step towards a new reality, one in which our daily energy is not derived from burning fossil fuels, is education. Ensuring that all citizens hold a basic understanding of energy is paramount in creating a populace that will willingly alter consumption behaviors while at the same time support renewable energy projects. Energy literacy education, both in K-12 and higher education institutions, fosters a new knowledge base for the next generation of citizens who will have to live with and address the challenges of climate change in the decades ahead. Through a hands-on, practical skill building curriculum students can develop an understanding of energy units as well as the connection between energy use and the health of the planet. Providing this solid understanding is critical to the future success of dealing with adaptation and mitigation. Given that there is no time to spare in implementing real change, it is imperative to create support for renewable energy generation in the present day. One effective means of achieving this support is to create opportunities within communities for small-scale renewable energy projects that both involve and benefit the local population. The positive outcomes of such projects are numerous and include

  6. THE SUBSTANTIATION OF THE METHODICAL APPROACH FOR ESTIMATION OF DYNAMICS OF DEVELOPMENT OF TECHNOLOGIES OF OFFSHORE WIND ENERGY USING (THE GERMAN EXAMPLE

    Full Text Available Purpose: the introduction of renewable energy technologies (RES occurs against the backdrop of a developed hydrocarbon energy market, which raises the risk of seeing unreasonable decisions by investors. The development and use of various analytical tools can reduce such risks. Economic models based on calculations by dozens of experts of a number of macro- and micro-economic factors have been used to study the replacement of traditional energy technologies with already developed RES technologies. At the same time, simpler but more effective econometric methods are being developed, based on the data of real projects and allowing to conduct research for the recently launched RES technologies. The main purpose of this article is to substantiate one of such methodologies used to asses growth dynamics of developing offshore wind energy based on the example of Germany – the leading country in the North Sea basin.Methods: many foreign and domestic authoritative organizations have developed a number of fairly complex models in order to study the economic substitution processes in fuel and energy complexes of different countries, calculate trends and forecasts in this area. Such models take into account findings of dozens of experts focusing on various macro and micro economic parameters and factors, including GDP, growth of employment, welfare, trade and many others. However, econometric methods based on the study of learning curves and calculations of the present value of LCOE electricity according to real energy projects tend to be simpler and effective tool used in order to estimates the recently developed RES technologies for which substantial volumes of data have not yet developed. This article considers substantiation of such methodical and mathematical approaches used to evaluate the dynamics of the development of offshore wind energy technologies using the model "Times model", modified by the author.Results: the feasibility analysis of using

    Percussive technology is part of the behavioural suite of several fossil and living primates. Stone Age ancestors used lithic artefacts in pounding activities, which could have been most important in the earliest stages of stone working. This has relevant evolutionary implications, as other primates such as chimpanzees and some monkeys use stone hammer-and-anvil combinations to crack hard-shelled foodstuffs. Parallels between primate percussive technologies and early archaeological sites need to be further explored in order to assess the emergence of technological behaviour in our evolutionary line, and firmly establish bridges between Primatology and Archaeology. What are the anatomical, cognitive and ecological constraints of percussive technology? How common are percussive activities in the Stone Age and among living primates? What is their functional significance? How similar are archaeological percussive tools and those made by non-human primates? This issue of Phil. Trans. addresses some of these questions by presenting case studies with a wide chronological, geographical and disciplinary coverage. The studies presented here cover studies of Brazilian capuchins, captive chimpanzees and chimpanzees in the wild, research on the use of percussive technology among modern humans and recent hunter-gatherers in Australia, the Near East and Europe, and archaeological examples of this behaviour from a million years ago to the Holocene. In summary, the breadth and depth of research compiled here should make this issue of Philosophical Transactions of the Royal Society B, a landmark step forward towards a better understanding of percussive technology, a unique behaviour shared by some modern and fossil primates. © 2015 The Author(s).

  8. Using Vision System Technologies for Offset Approaches in Low Visibility Operations

    Flight deck-based vision systems, such as Synthetic Vision Systems (SVS) and Enhanced Flight Vision Systems (EFVS), have the potential to provide additional margins of safety for aircrew performance and enable the implementation of operational improvements for low visibility surface, arrival, and departure operations in the terminal environment with equivalent efficiency to visual operations. Twelve air transport-rated crews participated in a motion-base simulation experiment to evaluate the use of SVS/EFVS in Next Generation Air Transportation System low visibility approach and landing operations at Chicago O'Hare airport. Three monochromatic, collimated head-up display (HUD) concepts (conventional HUD, SVS HUD, and EFVS HUD) and three instrument approach types (straight-in, 3-degree offset, 15-degree offset) were experimentally varied to test the efficacy of the SVS/EFVS HUD concepts for offset approach operations. The findings suggest making offset approaches in low visibility conditions with an EFVS HUD or SVS HUD appear feasible. Regardless of offset approach angle or HUD concept being flown, all approaches had comparable ILS tracking during the instrument segment and were within the lateral confines of the runway with acceptable sink rates during the visual segment of the approach.

  9. Does a too risk-averse approach to the implementation of new radiotherapy technologies delay their clinical use?

    Radiotherapy is a generally safe treatment modality in practice; nevertheless, recent well-reported accidents also confirm its potential risks. However, this may obstruct or delay the introduction of new technologies and treatment strategies/techniques into clinical practice. Risks must be addressed and judged in a realistic context: risks must be assessed realistically. Introducing new technology may introduce new possibilities of errors. However, delaying the introduction of such new technology therefore means that patients are denied the potentially better treatment opportunities. Despite the difficulty in quantitatively assessing the risks on both sides of the possible choice of actions, including the "lost opportunity", the best estimates should be included in the overall risk-benefit and cost-benefit analysis. Radiotherapy requires a sufficiently high level of support for the safety, precision and accuracy required: radiotherapy development and implementation is exciting. However, it has been anxious with a constant awareness of the consequences of mistakes or misunderstandings. Recent history can be used to show that for introduction of advanced radiotherapy, the risk-averse medical physicist can act as an electrical fuse in a complex circuit. The lack of sufficient medical physics resource or expertise can short out this fuse and leave systems unsafe. Future technological developments will continue to present further safety and risk challenges. The important evolution of radiotherapy brings different management opinions and strategies. Advanced radiotherapy technologies can and should be safely implemented in as timely a manner as possible for the patient groups where clinical benefit is indicated.

    participants enabled evaluation of administrative features of the app including the generation of automated email reminders, participation surveys, and daily AM file upload logs. This study describes the development of the PPAP app, a closed-loop technology framework that enables personalized physical activity prescription and remote monitoring of an individual's compliance and health response to the intervention. Data obtained during a 12-week feasibility study demonstrated the ability of the PPAP app to use objective AM data to create daily, personalized physical activity guidance, provide interactive feedback to users, and enable remote administrative monitoring of data quality and subject compliance. Using this approach, public health professionals, clinicians, and researchers can adapt the PPAP app to facilitate a range of personalized physical activity interventions to improve health outcomes, assess injury risk, and achieve fitness performance goals in diverse populations.

    Full Text Available The present study addresses the communication between professionals of information technology (IT and its users in the corporate environment of Curitiba (Brazil. The main aim was to analyze communication problems and implications for management and marketing. Empirical research examined responses from a sample of IT professionals with some professional experience in the area and academic level, as well as responses from a sample of IT users (making use of technology in that corporate environment. The questionnaires were available online, and the SPSS software was used for data processing. Results allow us to infer that, in the sample studied, problems in communication between IT professionals and the services’ users do exist. Data obtained reflect a need for formal training by the professionals to serve customers, manage their careers and use technology on behalf of users in order to improve business management practice. Professionals must be clear with users, to create confidence. Also, it was evident that respondent users consider technology as a basic tool, and they expect professionals to share and explain their actions toward the machine or system. This research makes some implications obvious in relation to communication processes in the IT field for management and marketing.
