    Full Text Available INTRODUCTION: Open access publishing is becoming increasingly popular within the biomedical sciences. SciELO, the Scientific Electronic Library Online, is a digital library covering a selected collection of Brazilian scientific journals many of which provide open access to full-text articles.This library includes a number of dental journals some of which may include reports of clinical trials in English, Portuguese and/or Spanish. Thus, SciELO could play an important role as a source of evidence for dental healthcare interventions especially if it yields a sizeable number of high quality reports. OBJECTIVE: The aim of this study was to identify reports of clinical trials by handsearching of dental journals that are accessible through SciELO, and to assess the overall quality of these reports. MATERIAL AND METHODS: Electronic versions of six Brazilian dental Journals indexed in SciELO were handsearched at www.scielo.br in September 2008. Reports of clinical trials were identified and classified as controlled clinical trials (CCTs - prospective, experimental studies comparing 2 or more healthcare interventions in human beings or randomized controlled trials (RCTs - a random allocation method is clearly reported, according to Cochrane eligibility criteria. CRITERIA TO ASSESS METHODOLOGICAL QUALITY INCLUDED: method of randomization, concealment of treatment allocation, blinded outcome assessment, handling of withdrawals and losses and whether an intention-to-treat analysis had been carried out. RESULTS: The search retrieved 33 CCTs and 43 RCTs. A majority of the reports provided no description of either the method of randomization (75.3% or concealment of the allocation sequence (84.2%. Participants and outcome assessors were reported as blinded in only 31.2% of the reports.

    Full Text Available http://dx.doi.org/10.5007/1980-0037.2009v11n2p217   A systematic review of original articles published between 1993 and 2007 and indexed in SciELO (Scientific Electronic Library Online was carried out to identify the anthropometric indicators used to assess abdominal obesity in different target subgroups, and to provide an overview of available evidence regarding the relationship between these anthropometric indicators and obesity-associated comorbidities. The articles were analyzed and the following data were collected:year of publication, sample size and age, anthropometric measure used to detect abdominal obesity, and main results of the study. The review comprised 47 articles which met all inclusion criteria, most of them published over the last 5 years. Waist-hip ratio and waist circumference were used as indicators of abdominal obesity in 34 and 11 of the articles reviewed, respectively. With respect to age range, the samples were heterogeneous in most of the studies (n=27 and ten included adolescents. Four studies were conducted on elderly subjects and three included children, but none exclusively involved adolescents as the target population. The sample size was larger than 500 in 26 studies. Despite disagreement in terms of the degree of correlation, the studies generally showed that the anthropometric indicators of abdominal obesity were correlated with hypertension, diabetes, dyslipidemias, and coronary heart risk. The results of this review suggest that abdominal obesity is associated with metabolic diseases. However, there is a lack of studies involving the adolescent population, suggesting the need for further research in this area.

    Interest in the quality of life construct has increased in the same proportion as the output of instruments to measure it. In order to analyze the scientific literature on the subject to provide a reflection on this construct in Brazil, a systematic review of the SciELO database covering the period from January 2001 to December 2006 was conducted. It was divided into 3 phases: the first involving 180 publications, the second 124, and the third 10. Of the 180 publications, 77.4% consisted of production in the last three years, with growth of 32.4% from 2001 to 2006. Of these, 124 were selected for methodological analysis in accordance with the category of the study: 79 (63.9%) instrument application articles; 25 (20.1%) translation, validation, adaptation and construction of a QOL instrument; 10 (8%) qualitative studies on QOL; 5 (4%) bibliographical review, 5 (4%) on the quality of life concept. The next stage involved the use of questionnaires and/or interview scripts in order to obtain a broader consensus on perceived quality of life from the interviewees. It was seen that there was significant scientific output in the period under scrutiny, with diversification of approaches and methodologies, highlighting the complexity of the quality of life construct.

    A three-digit electronic identification system is described. Digits may be decimal (1000 combinations) or hexidecimal (8192 combinations). Battery-powered transponders are interrogated with a lower-power (1 W) radio signal. Line-of-sight interrogations up to 33 m (100 ft) are possible. Successful interrogations up to 7 m (20 ft) are possible for concealed transponders (that is, in the engine compartment). Vehicles moving at high rates of speed can be interrogated. This system provides data in a computer-compatible RS232 format. The system can be used for other applications with little or no modification. A similar system is in present use for identification and temperature monitoring of livestock. No unforeseen problems exist for expanding the coding scheme to identify larger numbers of objects

Method: To achieve that, the required man-hours to publish a scientific paper were measured, using its new publication methodology called XML SPS. 40 articles published in scientific journals of different areas of knowledge are processed; journals from Brazil, Chile, Colombia, Mexico and Venezuela, using that methodology. Results showed that the preparation of the document takes on average 35% of the total time (σ = 9.72%, while the tagging process takes on average 50% of the time (σ = 8.50%, finally the sections corresponding to references, acknowledgments and appendices (back takes the majority of the time. Conclusions: This analysis indicates that the SciELO publishing model is sustainable from the point of view of the need for its existence, but in the economic terms seems not to be fully sustainable for all countries in the region, because it is a technically complex process that not all publishers are able to perform, making outsourcing of that procedure to be necessary, which requires a greater budget for the journal that can jeopardize the sustainability and the control of this publishing model.

    Single, Peg Boyle; Muller, Carol B.; Cunningham, Christine M.; Single, Richard M.

    In this article, we report on electronic discussion lists (e-lists) sponsored by MentorNet, the National Electronic Industrial Mentoring Network for Women in Engineering and Science. Using the Internet, the MentorNet program connects students in engineering and science with mentors working in industry. These e-lists are a feature of MentorNet's larger electronic mentoring program and were sponsored to foster the establishment of community among women engineering and science students and men and women professionals in those fields. This research supports the hypothesis that electronic communications can be used to develop community among engineering and science students and professionals and identifies factors influencing the emergence of electronic communities (e-communities). The e-lists that emerged into self-sustaining e-communities were focused on topic-based themes, such as balancing personal and work life, issues pertaining to women in engineering and science, and job searching. These e-communities were perceived to be safe places, embraced a diversity of opinions and experiences, and sanctioned personal and meaningful postings on the part of the participants. The e-communities maintained three to four simultaneous threaded discussions and were sustained by professionals who served as facilitators by seeding the e-lists with discussion topics. The e-lists were sponsored to provide women students participating in MentorNet with access to groups of technical and scientific professionals. In addition to providing benefits to the students, the e-lists also provided the professionals with opportunities to engage in peer mentoring with other, mostly female, technical and scientific professionals. We discuss the implications of our findings for developing e-communities and for serving the needs of women in technical and scientific fields.

  16. Review of scientific cases and beamline technology for x-ray free-electron laser

    2012-01-01

    We summarize the scientific cases and beamline technology for utilizing X-ray Free-Electron Lasers (XFELs). The scientific targets are classified into two categories: observation with ultrahigh spatio-temporal resolution and the creation of extreme states. As a representative of the former, the coherent diffraction imaging (CDI) method reveals the structure of non-crystalline samples with a single-shot exposure of the XFEL pulse. For the latter, nonlinear interactions between matter and short-wavelength radiation have been investigated. Combining optical lasers and XFEL with a pump and probe technique is a powerful tool for studying the ultrafast dynamics of materials. The state-of-the-art beamline technologies developed as SACLA are also introduced. (author)

    Previously, scientific silicon charge-coupled devices (CCDs) with 10.5-μm pixel pitch and a thick (650 μm), fully depleted bulk have been used to measure gamma-ray-induced fast electrons and demonstrate electron track Compton imaging. A model of the response of this CCD was also developed and benchmarked to experiment using Monte Carlo electron tracks. We now examine the trade-off in pixel pitch and electronic noise. We extend our CCD response model to different pixel pitch and readout noise per pixel, including pixel pitch of 2.5 μm, 5 μm, 10.5 μm, 20 μm, and 40 μm, and readout noise from 0 eV/pixel to 2 keV/pixel for 10.5 μm pixel pitch. The CCD images generated by this model using simulated electron tracks are processed by our trajectory reconstruction algorithm. The performance of the reconstruction algorithm defines the expected angular sensitivity as a function of electron energy, CCD pixel pitch, and readout noise per pixel. Results show that our existing pixel pitch of 10.5 μm is near optimal for our approach, because smaller pixels add little new information but are subject to greater statistical noise. In addition, we measured the readout noise per pixel for two different device temperatures in order to estimate the effect of temperature on the reconstruction algorithm performance, although the readout is not optimized for higher temperatures. The noise in our device at 240 K increases the FWHM of angular measurement error by no more than a factor of 2, from 26° to 49° FWHM for electrons between 425 keV and 480 keV. Therefore, a CCD could be used for electron-track-based imaging in a Peltier-cooled device.

    2011-01-01

    We have implemented benchmarked models to determine the gain in sensitivity of electron-tracking based Compton imaging relative to conventional Compton imaging by the use of high-resolution scientific charge-coupled devices (CCD). These models are based on the recently demonstrated ability of electron-tracking based Compton imaging by using fully depleted scientific CCDs. Here we evaluate the gain in sensitivity by employing Monte Carlo simulations in combination with advanced charge transport models to calculate two-dimensional charge distributions corresponding to experimentally obtained tracks. In order to reconstruct the angle of the incident γ-ray, a trajectory determination algorithm was used on each track and integrated into a back-projection routine utilizing a geodesic-vertex ray tracing technique. Analysis was performed for incident γ-ray energies of 662 keV and results show an increase in sensitivity consistent with tracking of the Compton electron to approximately ±30 o .

First, we describe how the development of electronic journals use follows a three-phase innovation process - research-development, first uses, and technical acculturation. Then, we attempt to find more significant explanatory factors, and emphasis is placed on the wider context of information activity. Three main information activity types are outlined - marginal, parallel, and integrated. Each of these types corresponds to a particular attitude towards scientific information and to different levels of electronic journal use.

  9. High-brightness electron beams for production of high intensity, coherent radiation for scientific and industrial applications

    Kim, K.-J.

    1999-01-01

    Relativistic electron beams with high six-dimensional phase space densities, i.e., high-brightness beams, are the basis for efficient generation of intense and coherent radiation beams for advanced scientific and industrial applications. The remarkable progress in synchrotrons radiation facilities from the first generation to the current, third-generation capability illustrates this point. With the recent development of the high-brightness electron gun based on laser-driven rf photocathodes, linacs have become another important option for high-brightness electron beams. With linacs of about 100 MeV, megawatt-class infrared free-electron lasers can be designed for industrial applications such as power beaming. With linacs of about 10 GeV, 1- angstrom x-ray beams with brightness and time resolution exceeding by several orders of magnitude the current synchrotrons radiation sources can be generated based on self-amplified spontaneous emission. Scattering of a high-brightness electron beam by high power laser beams is emerging as a compact method of generating short-pulse, bright x-rays. In the high-energy frontier, photons of TeV quantum energy could be generated by scattering laser beams with TeV electron beams in future linear colliders

  11. A three-phase model proposal for the evolution of scientific communication: from first print periodicals to current electronic communication system

    Directory of Open Access Journals (Sweden)

    Patrícia Bertin

    Full Text Available Scientific communication has undergone deep transformations, since the emergence of Internet. Aiming to provide further thought on the evolution of scientific communication, this paper features a historical overview of the scientific communication advances over the last twenty years through a three-phase model for the evolution of the electronic journal and the preprints services, and presents Brazilian contemporary panorama for scientific communication. The three-phase model presented in this work is an adaptation of that one proposed by Tenopir et al. (2003 to describe the patterns of journal use by scientists since 1990. The early evolutionary phase followed the emergence of the first digital journals and the creation of repositories in the Web for publishing preliminary versions of scientific literature on the author’s initiative; by that time, most academics reproved electronic publishing initiatives. From 1996 and forward, in the consolidation phase, electronic journals were commonly identical to their print counterparts; the acceptance of the electronic format began to increase, and preprint services got underway in several disciplines. The advanced evolutionary phase started with the world discussion on open access to scientific information. The comparison of the current electronic journal with that viewed by enthusiasts in the first years of the 1990s shows that some aspects still remain to be improved in electronic formal and informal communication, towards effective dissemination of scientific information.

Results Twenty-four per cent of medical students and ninteen per cent of dental students searched MEDLINE 2+ times/month for study purposes, and thiry-two per cent and twenty-four per cent respectively for research. Full-text articles were used 2+ times/month by thirty-three per cent of medical and ten per cent of dental students. Twelve per cent of respondents never utilized either MEDLINE or full-text articles. In multivariate models, the information-searching skills among students were significantly associated with use of MEDLINE and full-text articles. Conclusion Use of electronic resources differs among students. Forty percent were non-users of full-text articles. Information-searching skills are correlated with the use of electronic resources, but the level of basic PC skills plays not a major role in using these resources. The student data shows that adequate training in information-searching skills will increase the use of electronic information resources.

    A free-electron laser with a 38-MeV L-band linear accelerator was developed at the Institute of Scientific and Industrial Research, Osaka University. The self-amplified spontaneous emission was observed at wavelengths of 20 and 40 {mu}m with a high-intensity single-bunch beam passing through a wiggler. In the oscillation experiments with a multibunch beam laser light was obtained at wavelengths from 32 to 40 {mu}m. The peak power in a micropulse of the laser is estimated to be 8.3 MW at a wavelength of 40 {mu}m. In order to apply the laser to basic researches some components of the linac and the optical cavity are being improved. (author)

    This report is based largely on presentations and discussions at two workshops and contributions from workshop participants. The workshop on Fundamental Challenges in Electron-Driven Chemistry was held in Berkeley, October 9-10, 1998, and addressed questions regarding theory, computation, and simulation. The workshop on Electron-Driven Processes: Scientific Challenges and Technological Opportunities was held at Stevens Institute of Technology, March 16-17, 2000, and focused largely on experiments. Electron-molecule and electron-atom collisions initiate and drive almost all the relevant chemical processes associated with radiation chemistry, environmental chemistry, stability of waste repositories, plasma-enhanced chemical vapor deposition, plasma processing of materials for microelectronic devices and other applications, and novel light sources for research purposes (e.g. excimer lamps in the extreme ultraviolet) and in everyday lighting applications. The life sciences are a rapidly advancing field where the important role of electron-driven processes is only now beginning to be recognized. Many of the applications of electron-initiated chemical processes require results in the near term. A large-scale, multidisciplinary and collaborative effort should be mounted to solve these problems in a timely way so that their solution will have the needed impact on the urgent questions of understanding the physico-chemical processes initiated and driven by electron interactions.

    2013-08-01

    Electronic resources have evolved to become one of the most important resources within the library’s collection. The growths of these resources and the players involved within this area have provided library users with another alternative to obtain information. When implemented correctly with library assistance (library trainings, reference consultations and so forth), library users can access these electronic resources anywhere in the world with relative ease as long as there is an internet connection. Geographic barriers are no longer an issue and information can be obtained in a just-in-time manner. This paper describes how KAUST library built its electronic resources and how they grew into what it is today. Issues such as manpower, expertise level, budget, ERM tools, library-vendor relations and library-user communication will also be elaborated in the paper. Despite its drawbacks, KAUST library has managed to overcome most of them and strived to improve certain areas of concern. The paper will also describe the library’s ERM future directions and strategic planning. KAUST University was opened in September 2009 and it started out with its first cohort of 800 graduate students (25% female) taught by 100 faculties. The main areas of study focus on science and engineering divisions consisting mainly of: Mathematics and Computer Science, Physical Sciences and Life Sciences. From a demographic snapshot taken in 2010, 36% of the student body came from Saudi Arabia and the Middle East, 34% from Asia, 21% from Americas, 5% from Europe and 4% from Africa (alZahrani, R. , Branin, J. and Yi , 2012). The university library, when first started, had about 10 staff. The library is known to have a “state-of-the-art learning and information resource center supporting graduate education and advanced scientific research” (KAUST, 2010). The library subscribed to major science databases, electronic journals and books. It also offers a myriad of services from document

    The economic situation of scientific research is now very different from what it was in the early 1960s when Dr. Alvin Weinberg opened the debate on the criteria for scientific choice. Annual rates of growth of 10 per cent. or more in the budget for science were then common in most Western countries, while today scientists face the prospect of no growth at all or even a decline. Some progress has also been made in developing techniques for the evaluation of the scientific performance of research groups. These two facts make it interesting to reconsider the question of scientific choice. (author)

    Warburton, William K

    2009-03-06

    Superconducting tunnel junction (STJ) detectors offer a an approach to detecting soft x-rays with energy resolutions 4-5 times better and at rates 10 faster than traditions semiconductor detectors. To make such detectors feasible, however, then need to be deployed in large arrays of order 1000 detectors, which in turn implies that their processing electronics must be compact, fully computer controlled, and low cost per channel while still delivering ultra-low noise performance so as to not degrade the STJ's performance. We report on our progress in designing a compact, low cost preamplifier intended for this application. In particular, we were able to produce a prototype preamplifier of 2 sq-cm area and a parts cost of less than $30 that matched the energy resolution of the best conventional system to date and demonstrated its ability to acquire an STJ I-V curve under computer control, the critical step for determining and setting the detectors' operating points under software control.

    Infusion of Hibiscus sabdariffa (H. sabdariffa) is a very popular drink in many parts of the world. Its phytochemical composition is associated to antioxidant, hypotensive, and antiatherosclerotic effects. However, the molecular mechanisms involved in these processes are not well known. The aim of this review was to report the scientific evidence supporting that regular use of H. sabdariffa decreases oxidative stress, atherosclerosis, lipid profile, and blood pressure. A search of recent publications was made in the following specialized electronic databases: Elsevier Journal, SciELO, FSTA, Science Direct, Springer Link, and NCBI. Results of research conducted in clinical trials in humans and in animal models and cell cultures were recorded. Keywords used included Hibiscus sabdariffa, oxidative stress, polyphenols, hypertension, atherosclerosis, and lipid profile. Results of the different articles suggested a possible therapeutic effect of H. sabdariffa extracts on oxidative stress, lipid profile, hypertension, and atherosclerosis thanks to its composition rich in phenolic compounds. Anthocyanins significantly decrease LDL oxidation, inhibit adipogenesis by regulating adipogenic signaling pathways and transcription factors, and modulate gene expression of certain microRNAs. No adverse events or side effects were reported. Further more homogeneous, placebo-controlled studies in humans are needed to state that H. sabdariffa has therapeutic efficacy in humans.

  19. Adults' decision-making about the electronic waste issue: The role of the nature of science conceptualizations and moral concerns in socio-scientific decision-making

    Science.gov (United States)

    Yu, Yuqing

    Socio-scientific issues have become increasingly important in Science-Technology-Society (STS) education as a means to make science learning more relevant to students' lives. This study used the e-waste issue as a context to investigate two aspects of socio-scientific decision-making: (1) the relationship between the nature of science (NOS) conceptualizations and decision-making; and (2) moral concerns involved in the process of decision-making. This study contributes to the field of socio-scientific issue research and STS education in the following ways. First, it is the first study that performed meta-analysis to seek the relationship between the NOS understanding and decision-making. This study concludes that valuable NOS conceptualizations that are highly related to the socio-scientific issue under investigation, rather than general NOS understanding, exert statistically significant influences on decision-making. Second, this study empirically examined the Multiple Responses Model (MRM), which enables the transfer of qualitative NOS responses into quantitative data, and hence, inferential statistics. The current study justifies the significance of unidimensionality to the application of the MRM. It addresses the limitations associated with the MRM and provides implications for future use of the MRM in other contexts. Finally, the study explores the role of moral concerns in socio-scientific decision-making. Eight participants engaged in interviews that were designed to elicit their reactions and feelings regarding the issue of exporting e-waste to poor countries. Qualitative analyses demonstrated that moral considerations were significant influences on decision-making. In addition, participants' action responses revealed that they were motivated to take action to help the environment. The study has implications for socio-scientific issue studies in other contexts and for teacher education programs that use socio-scientific issues to advance teachers' reasoning

    The practice of science and engineering is being revolutionized by the development of cyberinfrastructure for accessing near real-time and archived observatory data. Large cyberinfrastructure projects have the potential to transform the way science is taught in high school classrooms, making enormous quantities of scientific data available, giving students opportunities to analyze and draw conclusions from many kinds of complex data, and providing students with experiences using state-of-the-art resources and techniques for scientific investigations. However, online interfaces to scientific data are built by scientists for scientists, and their design can significantly impede broad use by novices. Knowledge relevant to the design of student interfaces to complex scientific databases is broadly dispersed among disciplines ranging from cognitive science to computer science and cartography and is not easily accessible to designers of educational interfaces. To inform efforts at bridging scientific cyberinfrastructure to the high school classroom, Education Development Center, Inc. and the Scripps Institution of Oceanography conducted an NSF-funded 2-year interdisciplinary review of literature and expert opinion pertinent to making interfaces to large scientific databases accessible to and usable by precollege learners and their teachers. Project findings are grounded in the fundamentals of Cognitive Load Theory, Visual Perception, Schemata formation and Universal Design for Learning. The Knowledge Status Report (KSR) presents cross-cutting and visualization-specific guidelines that highlight how interface design features can address/ ameliorate challenges novice high school students face as they navigate complex databases to find data, and construct and look for patterns in maps, graphs, animations and other data visualizations. The guidelines present ways to make scientific databases more broadly accessible by: 1) adjusting the cognitive load imposed by the user

The formal division of communication processes into oral and written does not resolve the problem of attitude. The author defines successful communication as a win-win game, based on the respect and equality of the partners, regardless of their position in the world of science. The core characteristics of the process of scientific communication are indicated , such as openness, fairness, support, and creation. The task of creating the right atmosphere for science communication belongs to moderators, who should not allow privilege and differentiation of position to affect scientific communication processes.

    Today, for the first time, scientific concerns are seriously being addressed that span future times--hundreds, even thousands, or more years in the future. One is witnessing what the author calls scientific millenarianism. Are such concerns for the distant future exercises in futility, or are they real issues that, to the everlasting gratitude of future generations, this generation has identified, warned about and even suggested how to cope with in the distant future? Can the four potential catastrophes--bolide impact, CO 2 warming, radioactive wastes and thermonuclear war--be avoided by technical fixes, institutional responses, religion, or by doing nothing? These are the questions addressed in this paper

    In the last few years, bibliometric studies have proliferated, seeking to provide data on world research. This study analyzes the profile of the Brazilian scientific production in the A (H1N1) influenza field between 2009 and 2011. The research was conducted in MEDLINE, SciELO and LILACS databases, selecting papers in which the term "H1N1" and "Brazil" were defined as the main topics. The data were analyzed taking into consideration the Brazilian state and institution in which the articles were produced, the impact factor of the journal and the language. The research revealed 40 documents (27 from MEDLINE, 16 from SciELO and 24 from LILACS). The journal impact factor ranged from 0.0977 to 8.1230. A similar amount of articles were written in English and Portuguese and São Paulo was the most productive state in the country, with 95% of the Brazilian production originating from the Southern and Southeastern regions. Linguistic data indicate that previous efforts made in order to improve the scientific production of Brazilian researchers making their observations attain a broader scientific audience produced results. It is necessary to assess the scientific studies, especially those conducted with public funds, in order to ensure that the results will benefit society.

    2016-01-01

    This proposal involved the study of bacteria capable of transferring electrons from the bacterial cells to electron acceptors located outside the cell. These could be either insoluble minerals that were transformed into soluble products upon the addition of electrons, or they could be soluble salts like uranium or chromium, that become insoluble upon the addition of electrons. This process is called extracellular electron transport or EET, and can be done directly by cellular contact, or via conductive appendages called bacterial nanowires. In this work we examined a number of different bacteria for their ability to perform EET, and also looked at their ability to produce conductive nanowires that can be used for EET at a distance away from the EET-capable cells. In the work, new bacteria were isolated, new abilities of EET were examined, and many new methods were developed, and carefully described in the literature. These studies set the stage for future work dealing with the bioremediation of toxic metals like uranium and chromium. They also point out that EET (and conductive nanowires) are far more common that had been appreciated, and may be involved with energy transfer not only in sediments, but in symbioses between different bacteria, and in symbiosis/pathogenesis between bacteria and higher organisms.

Different study types, characterized by years, city/country of origin, journals and more productive authors, by country, cites and H index. At SCI, 2857 articles were found (17.7% of the total). Brazil was the highest producer (58.1%), followed by Colombia (9.9%) and Venezuela (5.6%); the region received 41186 citations, 54.2% of Brazil (H index=62), 12.1% Colombia (H index=30) and 4.5% of Venezuela (H index=25). At Scopus, there are 3681 (14.7% of the total), 53.2% Brazil, 6.8% Colombia and 6.0% Venezuela; 38.46% at Brazil were from Fundação Oswaldo Cruz; 30.6% of Colombia corresponded to Universidad de Antioquia; 31.34% at Venezuela were from Universidad Central de Venezuela. At Medline there are 4525 records (60.6% of Brazil). At SciELO there are 1068 records (67.5% Brazil). At LILACS, there are 1740 records (56.0% Brazil). Scientific production of Brazil predominates in the region, with one single institution generating more articles than Colombia and Venezuela together. Scientific production in bibliographical data bases, particularly regional, is still relatively low, and the disease neglected when compared to other tropical conditions such as dengue and malaria.

    Nitazoxanide is a member of a new class of drug, thiazolides, and it was discovered in 1984 with antimicrobial activity effect against anaerobic bacteria, Hepatitis virus, protozoa, and helminths. A bibliometric study on four databases (1984-2016) - Medline, Scopus, LILACS, and SciELO - characterizing the global scientific production of nitazoxanide. We determined the quantity, quality (number of citations), and types of studies developed by each country, characterizing them by years, international cooperation, development, place of publication, authors (with its H-index), and groups with higher impact. There were 512 articles in Medline - the higher scientific production is from the USA (19.71%), Switzerland (7.51%), and Mexico (7.27%). There were 1,440 articles in Scopus - from the USA (8.98%), Mexico (2.13%), and India (1.65%). There were 405 articles in LILACS - from Mexico (4.69%), the USA (4.2%), and Peru (2.47%). There were 47 articles in SciELO - from Brazil (34.04%), Venezuela (21.28%), and Colombia (14.89%). The H-index of nitazoxanide is 75 - the USA (26), Egypt (12), and Canada (10) were the countries contributing more with that. Nitazoxanide research has been highly important. Nevertheless, it is relatively limited when compared with other drugs. Its research has been led by the USA, as revealed in this bibliometric assessment. Although some developing countries, where it is used especially for protozoa and helminths, probably have its influence, and this explains the fact that Mexico and India, among others, are the top countries in the scientific production of this anti-infective agent. This bibliometric study evidenced a relatively low number of publications, however, it has been increased in recent years.

    2015-01-01

    The Medical Physics community lost one of its early pioneers in radiation oncology physics, Jacques Ovadia, who passed away in April of 2014 at the age of 90. Jacques received his Ph.D. in Nuclear Physics from the University of Illinois at Urbana in 1951. Subsequently, under the guidance of John Laughlin, he was introduced to the field of Medical Physics. When John moved to Memorial Sloan Kettering, Jacques followed him. There he gained clinical experience and expertise in the then cutting-edge field of high energy electron beam therapy. In 1956, Jacques joined Dr. Erich Uhlmann at Michael Reese Hospital in Chicago where one of the country’s first high energy medical linear accelerators had just been installed. During his 35 year tenure, Dr. Ovadia built a strong Medical Physics department that merged in 1984 with that of the University of Chicago. Jacques pioneered the use of high energy electron beams to treat deep seated tumors, multiple-field chest wall irradiation with variable electron energies, and even anticipated the current interest in high energy electron beam grid-therapy. At an early stage, he introduced a simulator, computerized treatment planning and in-house developed record and verify software. He retired in 1990 as Professor emeritus in Radiation and Cellular Biology at the University of Chicago. Dr. Ovadia was an early and strong supporter of AAPM. He was present at the Chicago ROMPS meeting where the decision was made to form an independent professional society for medical physics. He served as AAPM president in 1976. Jacques Ovadia is survived by his wife of 58 years, Florence, their daughter Corinne Graefe and son Marc Ovadia, MD, as well as four grandchildren and one great-grandchild. Jacques’ dynamic and ever enthusiastic personality inspired all who collaborated with him. He will be greatly missed

  17. Professional scientific blog

    Full Text Available The professional blog is a weblog that on the whole meets the requirements of scientific publication. In my opinion it bear a resemblance to digital notice board, where the competent specialists of the given branch of science can place their ideas, questions, possible solutions and can raise problems. Its most important function can be collectivization of the knowledge. In this article I am going to examine the characteristics of the scientific blog as a genre. Conventional learning counts as a rather solitary activity. If the students have access to the materials of each other and of the teacher, their sense of solitude diminishes and this model is also closer to the constructivist approach that features the way most people think and learn. Learning does not mean passively collecting tiny pieces of knowledge; it much more esembles ‘spinning a conceptual net’ which is made up by the experiences and observations of the individual. With the spreading of the Internet more universities and colleges worldwide gave a try to on-line educational methods, but the most efficient one has not been found yet. The publication of the curriculum (the material of the lectures and the handling of the electronic mails are not sufficient; much more is needed for collaborative learning. Our scholastic scientific blog can be a sufficient field for the start of a knowledge-building process based on cooperation. In the Rocard-report can be read that for the future of Europe it is crucial to develop the education of the natural sciences, and for this it isnecessary to act on local, regional, national and EU-level. To the educational processes should be involved beyond the traditional actors (child, parent, teacher also others (scientists, professionals, universities, local institutions, the actors of the economic sphere, etc.. The scholastic scientific blog answer the purposes, as a collaborative knowledge-sharing forum.

    Full Text Available Abstract Background The study aims to examine whether the end of specialty in trauma surgery in 2003 influenced the scientific productivity of the area in Brazil. Methods We identified and classified the manuscripts and their authors, from databases such as PubMed, Scielo and Plataforma Lattes and sites like Google, in addition to the list of members of SBAIT, the sole society in Brazil to congregate surgeons involved in trauma care in the country. We applied statistical tests to compare the periods of 1997-2003 and 2004-2010. We also analyzed the following variables: impact factor of journals in which manuscripts were published, journals, regional origin of authors, time since graduation, and conducting post-doctorate abroad. Results We observed a significant increase in publication rates of the analyzed groups over the years. There was a predominance of quantitative studies from the Southeast (especially the state of São Paulo. More time elapsed after graduation and the realization of postdoctoral studies abroad influenced the individual scientific productivity. Conclusion The number of articles published by authors from the area of trauma has been growing over the past 14 years in Brazil. The end of the specialty in trauma surgery in the country did not influence the scientific productivity in the area.

    2003-05-16

    The International Committee supported the proposal of the Chairman of the XVIII International Linac Conference to issue a new Compendium of linear accelerators. The last one was published in 1976. The Local Organizing Committee of Linac96 decided to set up a sub-committee for this purpose. Contrary to the catalogues of the High Energy Accelerators which compile accelerators with energies above 1 GeV, we have not defined a specific limit in energy. Microtrons and cyclotrons are not in this compendium. Also data from thousands of medical and industrial linacs has not been collected. Therefore, only scientific linacs are listed in the present compendium. Each linac found in this research and involved in a physics context was considered. It could be used, for example, either as an injector for high energy accelerators, or in nuclear physics, materials physics, free electron lasers or synchrotron light machines. Linear accelerators are developed in three continents only: America, Asia, and Europe. This geographical distribution is kept as a basis. The compendium contains the parameters and status of scientific linacs. Most of these linacs are operational. However, many facilities under construction or design studies are also included. A special mention has been made at the end for the studies of future linear colliders.

  4. Scientific instruments, scientific progress and the cyclotron

    Baird, David; Faust, Thomas

    1990-01-01

    Philosophers speak of science in terms of theory and experiment, yet when they speak of the progress of scientific knowledge they speak in terms of theory alone. In this article it is claimed that scientific knowledge consists of, among other things, scientific instruments and instrumental techniques and not simply of some kind of justified beliefs. It is argued that one aspect of scientific progress can be characterized relatively straightforwardly - the accumulation of new scientific instruments. The development of the cyclotron is taken to illustrate this point. Eight different activities which promoted the successful completion of the cyclotron are recognised. The importance is in the machine rather than the experiments which could be run on it and the focus is on how the cyclotron came into being, not how it was subsequently used. The completed instrument is seen as a useful unit of scientific progress in its own right. (UK)

    The Salton Sea Scientific Drilling Project, was spudded on 24 October 1985, and reached a total depth of 10,564 ft. (3. 2 km) on 17 March 1986. There followed a period of logging, a flow test, and downhole scientific measurements. The scientific goals were integrated smoothly with the engineering and economic objectives of the program and the ideal of 'science driving the drill' in continental scientific drilling projects was achieved in large measure. The principal scientific goals of the project were to study the physical and chemical processes involved in an active, magmatically driven hydrothermal system. To facilitate these studies, high priority was attached to four areas of sample and data collection, namely: (1) core and cuttings, (2) formation fluids, (3) geophysical logging, and (4) downhole physical measurements, particularly temperatures and pressures.

    Carrion's disease is a major re-emerging and occupational health disease. This bibliometric study aimed to evaluate scientific production on this disease both globally and in Latin America. SCI-E, MEDLINE/GoPubMed, SCOPUS, ScIELO, and LILACS databases were searched for Carrion's disease-related articles. They were classified according to publication year, type, city and institution of origin, international cooperation, scientific journal, impact factor, publication language, author(s), and H-index. There were 170 articles in SCI-E. The USA was the largest contributor (42.9%), followed by Peru (24.1%) and Spain (12.4%). Latin American publications were cited 811 times (regional H-index=18). There were 335 articles in SCOPUS: 25.9%, 11.6%, and 8.3% were published by the USA, Peru, and Spain, respectively. Latin American publications were cited 613 times (H-index=12): Peru, Colombia, and Brazil received the most citations (n=395, H-index=10; n=61, H-index=1; and n=54, H-index=4, respectively). The most scientifically productive American institution was the University of Montana (2.9% of American production). In Peru, it was the Institute of Tropical Medicine Alexander von Humboldt of Peruvian University Cayetano Heredia (6.5% of Peruvian scientific production). There were 3,802 articles in Medline (1.2% were Peruvian), 35 in SciELO (94.3% were from Peru), and 168 in LILACS (11% were published in 2010-2014; only one article was published in 2015). Scientific production worldwide is led by the USA, and, in Latin America, by Peru and Brazil. However, Latin American scientific production in bibliographic databases is much lower than in other regions, despite being an endemic area for Carrion's disease.

    This article focuses on scientific integrity and the identification of predisposing factors to scientific misconduct in Brazil. Brazilian scientific production has increased in the last ten years, but the quality of the articles has decreased. Pressure on researchers and students for increasing scientific production may contribute to scientific misconduct. Cases of misconduct in science have been recently denounced in the country. Brazil has important institutions for controlling ethical and safety aspects of human research, but there is a lack of specific offices to investigate suspected cases of misconduct and policies to deal with scientific dishonesty.

    Extensional scientific realism is the view that each believable scientific theory is supported by the unique first-order evidence for it and that if we want to believe that it is true, we should rely on its unique first-order evidence. In contrast, intensional scientific realism is the view that all believable scientific theories have a common feature and that we should rely on it to determine whether a theory is believable or not. Fitzpatrick argues that extensional realism is immune, while intensional realism is not, to the pessimistic induction. I reply that if extensional realism overcomes the pessimistic induction at all, that is because it implicitly relies on the theoretical resource of intensional realism. I also argue that extensional realism, by nature, cannot embed a criterion for distinguishing between believable and unbelievable theories. Copyright © 2016 Elsevier Ltd. All rights reserved.

  14. Electronic wastes

    Regel-Rosocka, Magdalena

    2018-03-01

    E-waste amount is growing at about 4% annually, and has become the fastest growing waste stream in the industrialized world. Over 50 million tons of e-waste are produced globally each year, and some of them end up in landfills causing danger of toxic chemicals leakage over time. E-waste is also sent to developing countries where informal processing of waste electrical and electronic equipment (WEEE) causes serious health and pollution problems. A huge interest in recovery of valuable metals from WEEE is clearly visible in a great number of scientific, popular scientific publications or government and industrial reports.

    Full Text Available It is quite impressive the visibility of online publishing compared to offline. Lawrence (2001 computed the percentage increase across 1,494 venues containing at least five offline and five online articles. Results shown an average of 336% more citations to online articles compared to offline articles published in the same venue. If articles published in the same venue are of similar quality, then they concluded that online articles are more highly cited because of their easier access. Thomson Scientific, traditionally concerned with printed journals, announced on November 28, 2005, the launch of Web Citation Index™, the multidisciplinary citation index of scholarly content from institutional and subject-based repositories (http://scientific.thomson. com/press/2005/8298416/. The Web Citation Index from the abstracting and indexing (A&I connects together pre-print articles, institutional repositories and open access (OA journals (Chillingworth, 2005. Basically all research funds are government granted funds, tax payer’s supported and therefore, results should be made freely available to the community. Free online availability facilitates access to research findings, maximizes interaction among research groups, and optimizes efforts and research funds efficiency. Therefore, Ambi-Água is committed to provide free access to its articles. An important aspect of Ambi-Água is the publication and management system of this journal. It uses the Electronic System for Journal Publishing (SEER - http://www.ibict.br/secao.php?cat=SEER. This system was translated and customized by the Brazilian Institute for Science and Technology Information (IBICT based on the software developed by the Public Knowledge Project (Open Journal Systems of the British Columbia University (http://pkp.sfu.ca/ojs/. The big advantage of using this system is that it is compatible with the OAI-PMH protocol for metadata harvesting what greatly promotes published articles

    The dissemination of the practice of collaborative authorship (coauthorship) in Brazil and in the international scientific community has been accompanied by an increasing occurrence of frauds, manipulations and other deviations in the assignment of responsibility for a scientific paper. This article discusses the criteria for authorship attribution, the reasons for the growing indices of coauthorship and the challenges to determine authorship in electronic journals. Through literature review and case study (bibliographic search in scientific database), it shows ways to avoid that "misbehaviors" related to the authorship attribution affect the credibility of science.

    2014-01-01

    Malaria is a parasitic disease of high global impact in public health, including Latin America. There should be more researched, particularly in this region. A bibliometric assessment of the Latin American contributions about malaria was done. Bibliometric study at SCI (1980-2013), MEDLINE/ GOPUBMED (1802-2013), Scopus (1959-2013), SCIELO (2004-2013), LILACS (1980-2013). The studies were characterized by study type, year of publication, city/country of origin, journals and more productive authors, citations and H index. At SCI, 2,806 articles were retrieved (5.13% of the total). Brazil was the highest producer (31.41%), followed by Colombia (14.3%) and Mexico (9.5%). The region received 39,894 citations, 32.2% from Brazil (H index=51), 12.75% Mexico (H index=38), 11.2% Colombia (H index=33). At Scopus, there are 4,150 articles (4.9% of the total), 33.0% Brazil, 11.3% Colombia and 8.8% Mexico; 17% in Brazil were from Universidad de São Paulo; 23.6% of Colombia from Universidad de Antioquia; 15.4% of Mexico from Instituto Nacional de Salud Pública. At Medline there were 4,278 records (36.8% Brazil). At SciELO there are 792 records (45.3% Brazil). At LILACS there were 1744 records (34.3% Brazil). Brazil has the highest output of the region, as Venezuela the scientific production in Malaria was related with the burden of disease. This was not the case for Colombia. Scientific production at bibliographical databases, particularly regionals, is low, compared to the high incidence of this disease that requires more research and control.

    Full Text Available Objective: To identify the most prevalent nursing ethical issues published in scientific Brazilian journals. Methods: A systematic literature review with the following inclusion criteria: (1 articles on Nursing Ethics written in Portuguese, English, French, and Spanish; (2 published in Brazilian journals; (3 in the period from January 1997 to February 2009. The search was carried out in four databases BDENF, LILACS, MEDLINE, and SCIELO. The key-words were ethics AND nursing. The selected studies were classified into categories. The content of the articles were analyzed using the Collective Subject Discourse. The categories generated discourses by organizing the main excerpts from the abstracts of the selected studies, which are the “key expressions”. Results: A hundred and thirty three articles that met the inclusion criteria were classified into eight categories: 1. Nursing Care; 2. Dilemmas and Controversies; 3. Education; 4. Legal Aspects; 5. Research; 6. Management; 7. Values and Beliefs; 8. Perspectives and Health Policies. The category “Nursing Care” prevailed in 36% of the selected articles, and it was classified into six subcategories. “Dilemmas and Controversies” was the second most prevalent category (15%. Conclusion: The number of theoretical papers on ethical issues is high, but there is little research on the ethical experiences in nursing practice.

    Full Text Available The objective of this study was to critically analyze the scientific production published in specialized Brazilian journals concerning the use of medicinal plants in dentistry. A literature review was carried out using an indirect documentation technique by means of a bibliographical study. Four examiners performed independent searches in Brazilian journals of medicinal plants indexed in the database SciELO (Brazilian Journal of Pharmacognosy; Brazilian Journal of Medicinal Plants; Brazilian Journal of Pharmaceutical Sciences; and Acta Botanica Brasilica using the descriptors "herbal medicine/phytotherapy" or "medicinal plants" and "dentistry ". The articles published from 2002 to 2012 addressing the use of medicinal plants in dentistry were included and analyzed. The searches based on the descriptors and reading of abstracts, resulted in 155 articles. Of these, 44 were read in full and a total of 16 publications met the eligibility criteria and were selected. Laboratory studies predominated (10 and were limited to the evaluation of antimicrobial properties by means of tests for determining inhibitory, fungicidal and bactericidal concentrations. Three literature reviews and only one clinical trial with no blinding and randomization were found. It is highlighted the need for better methodological designs in the researches and greater production of clinical or in vivo studies.

    Full Text Available In this article, the parameters used by RedALyC, Catalogo Latindex, SciELO, Scopus and Web of Science for the incorporation of scientific journals in their collections are analyzed with the goal of proving their relation with the objectives of each database in addition of debating the valuation that the scientific society is giving to those systems as decisive of "scientific quality". The used indicators are classified in: 1 Editorial quality (formal aspects or editorial management. 2 Content quality (peer review or originality and 3 Visibility (prestige of editors and editorial use and impact, accessibility and indexing It is revealed that: a between 9 and 16% of the indicators are related to the quality of content; b Lack specificity in their definition and determination of measure systems, and c match the goals of each base, although a marked trend towards formal aspects related and visibility is observed. Thus makes it clear that these systems pursuing their own objectives, making a core of journals of “quality” for its readership. We conclude, therefore, that the presence or absence of a journal in these collections is not sufficient to determine the quality of scientific magazine and its contents parameter.

  8. CERN Library - Scientific journal cancellations

    CERN Multimedia

    2004-01-01

    Due to the constant increase of the subscription costs of scientific journals and the current budget restrictions, the Scientific Information Policy Board has mandated the Working Group for Acquisitions (WGA) together with the Library to propose a list of titles to be cancelled at the end of 2004. As a first step, the WGA has identified the scientific journals listed at the web site below as candidates for cancellation. The choice has been guided by the personal experience of the WGA members, consultation of other expert CERN staff for highly specialized titles, and by criteria such as subscription price, impact factor, and - where available - access statistics for electronic journals. The list also accounts for the fact that many titles are subscribed to in 'packages' such that a cancellation of individual titles would not lead to any cost savings. We invite users to carefully check the list on the Library homepage (http://library.cern.ch/). If you find any title that you consider critically important for y...

    This comprehensive report on the activities at the Paul Scherrer Institute PSI in Switzerland reviews work done in 2010. Apart from reports on several projects being carried out at PSI, particular attention is given to the realization of the new Free-Electron Laser facility (SwissFEL) whose core was put into operation in 2010. The ability of the SwissFEL to rapidly initiate a catalytic process will allow the characterization of short-lived intermediate states and will aid in the development of more efficient catalysts. The various component parts of the facility are discussed in detail. Initial operation of the system and examples of the future use of the facility are discussed. The report goes on to report on research foci and selected highlights of work done. These include the Swiss Synchrotron Light Source which has seen another year of many highlights. Increasing experimental capabilities based on resonant soft X-ray absorption are described and four-dimensional measurements of the interface-kinetics of solid-liquid mixtures during coarsening are reported on. The handling of nano-volume crystallisation drops in the macromolecular crystallography beamline is described and the use of X-rays and neutrons at the micrometre scale to elucidate a metal artefact from the Bronze Age is discussed, as is the investigation of newly discovered iron-based superconductors with muons and neutrons. Neutron grating interferometry is reported on and over 14 years of successful operation of SINQ, PSI's Spallation Neutron Source, is looked back on, Fundamental muon physics is discussed and emergent magnetic monopoles that have been directly observed in a two-dimensional array of nanoscale magnets arranged in a honeycomb geometry is reported on.

    In a report released last week the National Academy of Sciences' Panel on Scientific Communication and National Security concluded that the ‘limited and uncertain benefits’ of controls on the dissemination of scientific and technological research are ‘outweighed by the importance of scientific progress, which open communication accelerates, to the overall welfare of the nation.’ The 18-member panel, chaired by Dale R. Corson, president emeritus of Cornell University, was created last spring (Eos, April 20, 1982, p. 241) to examine the delicate balance between open dissemination of scientific and technical information and the U.S. government's desire to protect scientific and technological achievements from being translated into military advantages for our political adversaries.The panel dealt almost exclusively with the relationship between the United States and the Soviet Union but noted that there are ‘clear problems in scientific communication and national security involving Third World countries.’ Further study of this matter is necessary.

    2015-01-01

    Before the results of a scientific computer simulation are used for any purpose, it should be determined if those results can be trusted. Answering that question of trust is the domain of scientific computer simulation review. There is limited literature that focuses on simulation review, and most is specific to the review of a particular type of simulation. This work is intended to provide a foundation for a common understanding of simulation review. This is accomplished through three contributions. First, scientific computer simulation review is formally defined. This definition identifies the scope of simulation review and provides the boundaries of the review process. Second, maturity assessment theory is developed. This development clarifies the concepts of maturity criteria, maturity assessment sets, and maturity assessment frameworks, which are essential for performing simulation review. Finally, simulation review is described as the application of a maturity assessment framework. This is illustrated through evaluating a simulation review performed by the U.S. Nuclear Regulatory Commission. In making these contributions, this work provides a means for a more objective assessment of a simulation’s trustworthiness and takes the next step in establishing scientific computer simulation review as its own field. - Highlights: • We define scientific computer simulation review. • We develop maturity assessment theory. • We formally define a maturity assessment framework. • We describe simulation review as the application of a maturity framework. • We provide an example of a simulation review using a maturity framework

    In the words of the UK government chief scientific adviser "Science is not finished until it's communicated" (Walport 2013). The tools to produce good visual communication have never been so easily accessible to scientists as at the present. Correspondingly, it has never been easier to produce and disseminate poor graphics. In this presentation, we highlight some good practice and offer some practical advice in preparing scientific figures for presentation to peers or to the public. We identify common mistakes in visualisation, including some made by the authors, and offer some good reasons not to trust defaults in graphics software. In particular, we discuss the use of colour scales and share our experiences in running a social media campaign (http://tiny.cc/endrainbow) to replace the "rainbow" (also "jet", or "spectral") colour scale as the default in (climate) scientific visualisation.

    Scientific publishing is the ultimate product of scientist work. Number of publications and their quoting are measures of scientist success while unpublished researches are invisible to the scientific community, and as such nonexistent. Researchers in their work rely on their predecessors, while the extent of use of one scientist work, as a source for the work of other authors is the verification of its contributions to the growth of human knowledge. If the author has published an article in a scientific journal it cannot publish the article in any other journal h with a few minor adjustments or without quoting parts of the first article, which are used in another article. Copyright infringement occurs when the author of a new article with or without the mentioning the author used substantial portions of previously published articles, including tables and figures. Scientific institutions and universities should,in accordance with the principles of Good Scientific Practice (GSP) and Good Laboratory Practices (GLP) have a center for monitoring,security, promotion and development of quality research. Establish rules and compliance to rules of good scientific practice are the obligations of each research institutions,universities and every individual-researchers,regardless of which area of science is investigated. In this way, internal quality control ensures that a research institution such as a university, assume responsibility for creating an environment that promotes standards of excellence, intellectual honesty and legality. Although the truth should be the aim of scientific research, it is not guiding fact for all scientists. The best way to reach the truth in its study and to avoid the methodological and ethical mistakes is to consistently apply scientific methods and ethical standards in research. Although variously defined plagiarism is basically intended to deceive the reader's own scientific contribution. There is no general regulation of control of

  13. Recording Scientific Knowledge

    International Nuclear Information System (INIS)

    Bowker, Geof

    2006-01-01

    The way we record knowledge, and the web of technical, formal, and social practices that surrounds it, inevitably affects the knowledge that we record. The ways we hold knowledge about the past - in handwritten manuscripts, in printed books, in file folders, in databases - shape the kind of stories we tell about that past. In this talk, I look at how over the past two hundred years, information technology has affected the nature and production of scientific knowledge. Further, I explore ways in which the emergent new cyberinfrastructure is changing our relationship to scientific practice.

  16. Access to the scientific literature

    Science.gov (United States)

    Albarède, Francis

    The Public Library of Science Open Letter (http://www.publiclibraryofscience.org) is a very generous initiative, but, as most similar initiatives since the advent of electronic publishing, it misses the critical aspects of electronic publishing.Ten years ago, a Publisher would be in charge of running a system called a “scientific journal.” In such a system, the presence of an Editor and peer Reviewers secures the strength of the science and the rigor of writing; the Publisher guarantees the professional quality of printing, efficient dissemination, and long-term archiving. Publishing used to be in everyone's best interest, or nearly everyone. The Publisher, because he/she is financially motivated, ensures widespread dissemination of the journal amongst libraries and individual subscribers. The interest of the Author is that the system guarantees a broad potential readership. The interest of the Reader is that a line is drawn between professionally edited literature, presumably of better quality, and gray literature or home publishing, so that he/she does not waste time going through ‘low yield’ ungraded information. The Publisher could either be a private company, an academic institution, or a scholarly society. My experience is that, when page charges and subscription rates are compounded, journals published by scholarly societies are not necessarily cheaper. The difference between these cases is not the cost of running an office with rents, wages, printing, postage, advertisement, and archiving, but that a private Publisher pays shareholders. Shareholders have the bad habit of minding their own business and, therefore, they may interfere negatively with scientific publishing. Nevertheless, while the stranglehold imposed by private Publishers on our libraries over the last 10 years by increasing subscription rates may in part be due to shareholders' greed, this is true only in part. The increases are also a consequence of the booming number of pages being

  6. Is risk analysis scientific?

    Science.gov (United States)

    Hansson, Sven Ove; Aven, Terje

    2014-07-01

    This article discusses to what extent risk analysis is scientific in view of a set of commonly used definitions and criteria. We consider scientific knowledge to be characterized by its subject matter, its success in developing the best available knowledge in its fields of study, and the epistemic norms and values that guide scientific investigations. We proceed to assess the field of risk analysis according to these criteria. For this purpose, we use a model for risk analysis in which science is used as a base for decision making on risks, which covers the five elements evidence, knowledge base, broad risk evaluation, managerial review and judgment, and the decision; and that relates these elements to the domains experts and decisionmakers, and to the domains fact-based or value-based. We conclude that risk analysis is a scientific field of study, when understood as consisting primarily of (i) knowledge about risk-related phenomena, processes, events, etc., and (ii) concepts, theories, frameworks, approaches, principles, methods and models to understand, assess, characterize, communicate, and manage risk, in general and for specific applications (the instrumental part). © 2014 Society for Risk Analysis.

    2016-12-01

    The Scientific Tourism is relatively new direction in the world, however it already has managed to gain great popularity. As it is, it has arisen in 1980s, but its ideological basis comes from the earliest periods of the human history. In Armenia, it is a completely new phenomenon and still not-understandable for many people. At global level, the Scientific Tourism has several definitions: for example, as explains the member of the scientific tourist centre of Zlovlen Mrs. Pichelerova "The essence of the scientific tourism is based on the provision of the educational, cultural and entertainment needs of a group of people of people who are interested in the same thing", which in our opinion is a very comprehensive and discreet definition. We also have our own views on this type of tourism. Our philosophy is that by keeping the total principles, we put the emphasis on the strengthening of science-individual ties. Our main emphasis is on the scientific-experimental tourism. But this does not mean that we do not take steps to other forms of tourism. Studying the global experience and combining it with our resources, we are trying to get a new interdisciplinary science, which will bring together a number of different professionals as well as individuals, and as a result will have a new lore. It is in this way that an astronomer will become an archaeologist, an archaeologist will become an astrophysicist, etc. Speaking on interdisciplinary sciences, it's worth mentioning that in recent years, the role of interdisciplinary sciences at global level every day is being considered more and more important. In these terms, tourism is an excellent platform for the creation of interdisciplinary sciences and, therefore, the preparation of corresponding scholars. Nevertheless, scientific tourism is very important for the revelation, appreciation and promotion of the country's historical-cultural heritage and scientific potential. Let us not forget either that tourism in all its

    2009-06-01

    Full Text Available INTRODUCTION: The present study was motivated by the need to systematically assess the research productivity of the Heart Institute (InCor, Medical School of the University of São Paulo, Brazil. OBJECTIVE: To explore methodology for the assessment of institutional scientific research productivity. MATERIALS AND METHODS: Bibliometric indicators based on searches for author affiliation of original scientific articles or reviews published in journals indexed in the databases Web of Science, MEDLINE, EMBASE, LILACS and SciELO from January 2000 to December 2003 were used in this study. The retrieved records were analyzed according to the index parameters of the journals and modes of access. The number of citations was used to calculate the institutional impact factor. RESULTS: Out of 1253 records retrieved from the five databases, 604 original articles and reviews were analyzed; of these, 246 (41% articles were published in national journals and 221 (90% of those were in journals with free online access through SciELO or their own websites. Of the 358 articles published in international journals, 333 (93% had controlled online access and 223 (67% were available through the Capes Portal of Journals. The average impact of each article for InCor was 2.224 in the period studied. CONCLUSION: A simple and practical methodology to evaluate the scientific production of health research institutions includes searches in the LILACS database for national journals and in MEDLINE and the Web of Science for international journals. The institutional impact factor of articles indexed in the Web of Science may serve as a measure by which to assess and review the scientific productivity of a research institution.

    2007-01-01

    Full Text Available The Fortran programming language was designed by John Backus and his colleagues at IBM to reduce the cost of programming scientific applications. IBM delivered the first compiler for its model 704 in 1957. IBM's competitors soon offered incompatible versions. ANSI (ASA at the time developed a standard, largely based on IBM's Fortran IV in 1966. Revisions of the standard were produced in 1977, 1990, 1995 and 2003. Development of a revision, scheduled for 2008, is under way. Unlike most other programming languages, Fortran is periodically revised to keep pace with developments in language and processor design, while revisions largely preserve compatibility with previous versions. Throughout, the focus on scientific programming, and especially on efficient generated programs, has been maintained.

Although, its existence dates back to 17 th century in the West, Nepal is still struggling to take few steps towards improving its local science for last 50 years. Since the start of the first medical journal in 1963, the challenges remains as it were decades back regarding role of authors, peer reviewers, editors and even publishers in Nepal. Although, there has been some development in terms of the number of articles being published and appearances of the journals, yet there is a long way to go. This article analyzes the past and present scenario, and future perspective for scientific publications in Nepal.

  9. Sherlock Holmes: scientific detective.

    Science.gov (United States)

    Snyder, Laura J

    2004-09-01

    Sherlock Holmes was intended by his creator, Arthur Conan Doyle, to be a 'scientific detective'. Conan Doyle criticized his predecessor Edgar Allan Poe for giving his creation - Inspector Dupin - only the 'illusion' of scientific method. Conan Doyle believed that he had succeeded where Poe had failed; thus, he has Watson remark that Holmes has 'brought detection as near an exact science as it will ever be brought into the world.' By examining Holmes' methods, it becomes clear that Conan Doyle modelled them on certain images of science that were popular in mid- to late-19th century Britain. Contrary to a common view, it is also evident that rather than being responsible for the invention of forensic science, the creation of Holmes was influenced by the early development of it.

    This monograph investigates the collaborative creation of scientific knowledge in research groups. To do so, I combine philosophical analysis with a first-hand comparative case study of two research groups in experimental science. Qualitative data are gained through observation and interviews......, and I combine empirical insights with existing approaches to knowledge creation in philosophy of science and social epistemology. On the basis of my empirically-grounded analysis I make several conceptual contributions. I study scientific collaboration as the interaction of scientists within research...... to their publication. Specifically, I suggest epistemic difference and the porosity of social structure as two conceptual leitmotifs in the study of group collaboration. With epistemic difference, I emphasize the value of socio-cognitive heterogeneity in group collaboration. With porosity, I underline the fact...

    Inquisitive minds in our society are never satisfied with curatedimages released by a typical public affairs office. They always want tolook deeper and play directly on original data. However, most scientificdata products are notoriously hard to use. They are immensely large,highly distributed and diverse in format. In this presentation,we will demonstrate Resource EXplorer (REX), a novel webtop applicationthat allows anyone to conveniently explore and visualize rich scientificdata repositories, using only a standard web browser. This tool leverageson the power of Webification Science (w10n-sci), a powerful enabling technologythat simplifies the use of scientific data on the web platform.W10n-sci is now being deployed at an increasing number of NASA data centers,some of which are the largest digital treasure troves in our nation.With REX, these wonderful scientific resources are open for teachers andstudents to learn and play.

We hypothesized that study participants would be less effective, report more difficulty, and be less favorably inclined to adopt the system when collaborating remotely. Contrary to expectations...... of collaborating remotely. While the data analysis produced null results, considered as a whole, the analysis leads us to conclude there is positive potential for the development and adoption of scientific collaboratory systems....

    Full Text Available During the last three decades of the nineteenth century, organizations developed rapidly, their managers began to realize that they had too frequent managerial problems; this awareness lead to a new phase of development of scientific management. Examining the titles published in that period, it can be concluded that management issues that pose interest related to payroll and payroll systems, problems exacerbated by the industrial revolution and related work efficiency. Noting that large organizations losing power, direct supervision, the managers were looking for incentives to replace this power . One of the first practitioners of this new management system was Henry R. Towne, the president of the well-known enterprise "Yale and Towne Manufacturing Company", which applied the management methods in his company workshops. Publishers of magazines "Industrial Management" and "The Engineering Magazine" stated that HR Towne is, undisputedly, the pioneer of scientific management. He initiated the systematic application of effective management methods and his famous article "The Engineer as Economist" provided to the company. "American Society of Mechanical Engineers" in 1886 was the one that probably inspired Frederick W. Taylor to devote his entire life and work in scientific management.

    For decades, computer scientists have tried to teach computers to think like human experts. Until recently, most of those efforts have failed to come close to generating the creative insights and solutions that seem to come naturally to the best researchers, doctors, and engineers. But now, Tony Hey, a VP of Microsoft Research, says we're witnessing the dawn of a new generation of powerful computer tools that can "mash up" vast quantities of data from many sources, analyze them, and help produce revolutionary scientific discoveries. Hey and his colleagues call this new method of scientific exploration "machine learning." At Microsoft, a team has already used it to innovate a method of predicting with impressive accuracy whether a patient with congestive heart failure who is released from the hospital will be readmitted within 30 days. It was developed by directing a computer program to pore through hundreds of thousands of data points on 300,000 patients and "learn" the profiles of patients most likely to be rehospitalized. The economic impact of this prediction tool could be huge: If a hospital understands the likelihood that a patient will "bounce back," it can design programs to keep him stable and save thousands of dollars in health care costs. Similar efforts to uncover important correlations that could lead to scientific breakthroughs are under way in oceanography, conservation, and AIDS research. And in business, deep data exploration has the potential to unearth critical insights about customers, supply chains, advertising effectiveness, and more.

    de complexidade dos estudos publicados, bem como de maior multidisciplinaridade. A Revista parece alargar seu alcance e repercussão embora continue fiel aos temas de interesse da saúde pública do Brasil.OBJECTIVE: To recognize the characteristics and path taken by the through analysis of the scientific production it has published over the period from 1967 to 2005. METHODS: Scientometric methods were used to analyze reference data on the articles published in the Revista, retrieved from the databases ISI/Thomson Scientific (Web of Science, National Library of Medicine (PubMed and Scientific Electronic Library Online (SciELO. RESULTS: The Revista is the only Brazilian publication in the field of public health that is indexed by ISI/Thomson Scientific. It is prominent as a medium for publishing Brazilian scientific production in public health and is displaying a geometric increase in publication and citation, with annual rates of 4.4% and 12.7%, respectively. The mean number of authors per paper has risen from 2 to 3.5 over recent years. Although original research articles predominate, the numbers of reviews, multicenter studies, clinical trials and validation studies have been increasing. The number of articles published in foreign languages has also increased, accounting for 13% of the total, and the leading countries originating these are the UK, USA, Argentina and Mexico. The number and diversity of journals citing the Journal has been increasing, many of which are non-Brazilian. Authorship per author shows good fit to Lotka's Law, but the parameters suggest greater concentration and less dispersion than would be expected. Among the fields of interest of published papers, the following topics account for more than 50% of the total volume: infectious-parasitic diseases and vectors; health promotion, policies and administration; and epidemiology, surveillance and disease control. CONCLUSIONS: The Revista shows great dynamism, without signs of abating or reaching a

    The scope of this article is to analyze the characteristics of scientific literature on work and education in health in Brazil from 1990 to 2010. A synthetic study was conducted from abstracts published in Brazilian journal articles selected from the SCIELO and LILACS databases. Five hundred and thirty-two articles were selected, categorized according to their origin, year of publication, theme, and type of study. The publication of these scientific articles increased during the period analyzed, particularly from 2007 onwards. The main areas researched were education and training of health professionals, and the majority of works in these areas examine curriculum reform, methods of learning and teaching, and teaching in-service experiences. Besides these issues, others questions were addressed such as the labor market configuration and trends in health, and characteristics of the work process in several areas, like primary healthcare units. It was also observed that there are only a small number of studies related to policy, planning and management of work in public and private health institutions, as well as a scarcity of studies presenting reflections on theoretical and conceptual aspects of this theme.

    Full Text Available Interest in open access (OA to scientific publications is steadily increasing, both in Norway and internationally. From the outset, FORMakademisk has been published as a digital journal, and it was one of the first to offer OA in Norway. We have since the beginning used Open Journal Systems (OJS as publishing software. OJS is part of the Public Knowledge Project (PKP, which was created by Canadian John Willinsky and colleagues at the Faculty of Education at the University of British Columbia in 1998. The first version of OJS came as an open source software in 2001. The programme is free for everyone to use and is part of a larger collective movement wherein knowledge is shared. When FORMakademisk started in 2008, we received much help from the journal Acta Didactic (n.d. at the University of Oslo, which had started the year before us. They had also translated the programme to Norwegian. From the start, we were able to publish in both Norwegian and English. Other journals have used FORMakademisk as a model and source of inspiration when starting or when converting from subscription-based print journals to electronic OA, including the Journal of Norwegian Media Researchers [Norsk medietidsskrift]. It is in this way that the movement around PKP works and continues to grow to provide free access to research. As the articles are OA, they are also easily accessible to non-scientists. We also emphasise that the language should be readily available, although it should maintain a high scientific quality. Often there may be two sides of the same coin. We on the editorial team are now looking forward to adopting the newly developed OJS 3 this spring, with many new features and an improved design for users, including authors, peer reviewers, editors and readers.

  7. Marie Curie: scientific entrepreneur

    International Nuclear Information System (INIS)

    Boudia, S.

    1998-01-01

    Marie Curie is best known for her discovery of radium one hundred years ago this month, but she also worked closely with industry in developing methods to make and monitor radioactive material, as Soraya Boudia explains. One hundred years ago this month, on 28 December 1898, Pierre Curie, Marie Sklodowska-Curie and Gustave Bemont published a paper in Comptes-rendus - the journal of the French Academy of Sciences. In the paper they announced that they had discovered a new element with astonishing properties: radium. But for one of the authors, Marie Curie, the paper was more than just the result of outstanding work: it showed that a woman could succeed in what was then very much a male-dominated scientific world. Having arrived in Paris from Poland in 1891, Marie Curie became the first woman in France to obtain a PhD in physics, the first woman to win a Nobel prize and the first woman to teach at the Sorbonne. She also helped to found a new scientific discipline: the study of radioactivity. She became an icon and a role-model for other women to follow, someone who succeeded - despite many difficulties - in imposing herself on the world of science. Although Curie's life story is a familiar and well documented one, there is one side to her that is less well known: her interaction with industry. As well as training many nuclear physicists and radiochemists in her laboratory, she also became a scientific pioneer in industrial collaboration. In this article the author describes this side of Marie Curie. (UK)

    Energy communication is a paradigmatic case of scientific communication. It is particularly important today, when the world is confronted with a number of immediate, urgent problems. Science communication has become a real duty and a big challenge for scientists. It serves to create and foster a climate of reciprocal knowledge and trust between science and society, and to establish a good level of interest and enthusiasm for research. For an effective communication it is important to establish an open dialogue with the audience, and a close collaboration among scientists and science communicators. An international collaboration in energy communication is appropriate to better support international and interdisciplinary research and projects.

    In the past decade, a number of scientific collaboratories have emerged, yet adoption of scientific collaboratories remains limited. Meeting expectations is one factor that influences adoption of innovations, including scientific collaboratories. This paper investigates expectations scientists have...... with respect to scientific collaboratories. Interviews were conducted with 17 scientists who work in a variety of settings and have a range of experience conducting and managing scientific research. Results indicate that scientists expect a collaboratory to: support their strategic plans; facilitate management...... of the scientific process; have a positive or neutral impact on scientific outcomes; provide advantages and disadvantages for scientific task execution; and provide personal conveniences when collaborating across distances. These results both confirm existing knowledge and raise new issues for the design...

  20. Metadata in Scientific Dialects

    Science.gov (United States)

    Habermann, T.

    2011-12-01

    Discussions of standards in the scientific community have been compared to religious wars for many years. The only things scientists agree on in these battles are either "standards are not useful" or "everyone can benefit from using my standard". Instead of achieving the goal of facilitating interoperable communities, in many cases the standards have served to build yet another barrier between communities. Some important progress towards diminishing these obstacles has been made in the data layer with the merger of the NetCDF and HDF scientific data formats. The universal adoption of XML as the standard for representing metadata and the recent adoption of ISO metadata standards by many groups around the world suggests that similar convergence is underway in the metadata layer. At the same time, scientists and tools will likely need support for native tongues for some time. I will describe an approach that combines re-usable metadata "components" and restful web services that provide those components in many dialects. This approach uses advanced XML concepts of referencing and linking to construct complete records that include reusable components and builds on the ISO Standards as the "unabridged dictionary" that encompasses the content of many other dialects.

    This guidebook introduces the reader—the scientific tourist and others—to the visible memorabilia of science and scientists in Budapest—statues, busts, plaques, buildings, and other artefacts. According to the Hungarian–American Nobel laureate Albert Szent-Györgyi, this metropolis at the crossroads of Europe has a special atmosphere of respect for science. It has been the venue of numerous scientific achievements and the cradle, literally, of many individuals who in Hungary, and even more beyond its borders became world-renowned contributors to science and culture. Six of the eight chapters of the book cover the Hungarian Nobel laureates, the Hungarian Academy of Sciences, the university, the medical school, agricultural sciences, and technology and engineering. One chapter is about selected gimnáziums from which seven Nobel laureates (Szent-Györgyi, de Hevesy, Wigner, Gabor, Harsanyi, Olah, and Kertész) and the five “Martians of Science” (von Kármán, Szilard, Wigner, von Neumann, and Teller...

The examples given here are the generally accepted regulations in regards to technology (that is sections 7a and 18b of the WHG (law on water economy), section 3, sub-section 1 of the machine- and engine protection laws) and to the status of technology (section 3, sub-section 6 of the BImSchG (Fed. law on prevention of air-borne pollution)), and to the status of science (section 5, sub-section 2 of the AMG (drug legislation). The ''status of science and technology'' as defined in sections 4 ff of the Atomic Energy Law (AtomG) and in sections 3, 4, 12, 2) of the First Radiation Protection Ordinance (1.StrlSch. VO), is also being discussed. The author defines the in his opinion ''dynamic term'' as the generally recognized result of scientific research, and the respective possibilities of practical utilization of technology. (orig.) [de

    Drilling for scientific purpose is a process of conducting geophysical exploration at deep underground and drilling for collecting crust samples directly. This is because earth science has advanced to get a good understanding about the top of the crust and has shifted its main interest to the lower layer of the crust in land regions. The on-land drilling plan in Japan has just started, and the planned drilling spots are areas around the Minami River, Hidaka Mts., kinds of the Mesozoic and Cenozoic granite in outside zone, the extension of Japan Sea, Ogasawara Is., Minami-Tori Is., and active volcanos. The paper also outlines the present situation of on-land drilling in the world, focusing on the SG-3rd super-deep well SG-3 on the Kola Peninsula, USSR, Satori SG-1st well SG-1 in Azerbaidzhan S.S.R, V.S.S.R, Sweden's wells, Cyprus' wells, Bayearn well Plan in West Germany, and Salton Sea Scientific Drilling Program in the U.S. At its end, the paper explains the present situation and the future theme of the Japanese drilling technique and points out the necessity of developing equipment, and techniques.

    2014-01-01

    We use citation data of scientific articles produced by individual nations in different scientific domains to determine the structure and efficiency of national research systems. We characterize the scientific fitness of each nation-that is, the competitiveness of its research system-and the complexity of each scientific domain by means of a non-linear iterative algorithm able to assess quantitatively the advantage of scientific diversification. We find that technological leading nations, beyond having the largest production of scientific papers and the largest number of citations, do not specialize in a few scientific domains. Rather, they diversify as much as possible their research system. On the other side, less developed nations are competitive only in scientific domains where also many other nations are present. Diversification thus represents the key element that correlates with scientific and technological competitiveness. A remarkable implication of this structure of the scientific competition is that the scientific domains playing the role of "markers" of national scientific competitiveness are those not necessarily of high technological requirements, but rather addressing the most "sophisticated" needs of the society.

  9. Instructional scientific humor in the secondary classroom

    Science.gov (United States)

    Wizner, Francine

    This study is an examination of the manner in which educators employ scientific content humor and how that humor is perceived by their students. Content humor is a useful strategy in drawing the attention of students and improving their receptivity toward scientific information. It is also a useful tool in combating the growing distractions of the electronic classroom. Previous studies have found that humor has a positive effect on knowledge, memory, and understanding. However, few studies have been conducted below the undergraduate level and mainly quantitative measures of student recall have been used to measure learning. This study employed multiple data sources to determine how two secondary biology teachers used humor in order to explain scientific concepts and how their students perceived their teachers' use of scientific instructional humor. Evidence of student humor reception was collected from four students in each of the two classes. All of the scientific instructional humor used in the studied classrooms was cognitive in nature, varying among factual, procedural, conceptual, and metacognitive knowledge. Teachers tended to use dialogic forms of humor. Their scientific humor reflected everyday experiences, presented queries, poked fun at authority, and asked students to search out new perspectives and perform thought experiments. Teachers were the primary actors in performing the humorous events. The events were sometimes physical exaggerations of words or drawings, and they occurred for the purpose of establishing rapport or having students make connections between scientific concepts and prior knowledge. Student perceptions were that teachers did employ humor toward instructional objectives that helped their learning. Helping students become critical thinkers is a trademark of science teachers. Science teachers who take the risk of adopting some attributes of comedians may earn the reward of imparting behaviors on their students like critical thinking

    Harvey, R.W.

    2009-01-01

    This DOE grant supported fusion energy research, a potential long-term solution to the world's energy needs. Magnetic fusion, exemplified by confinement of very hot ionized gases, i.e., plasmas, in donut-shaped tokamak vessels is a leading approach for this energy source. Thus far, a mixture of hydrogen isotopes has produced 10's of megawatts of fusion power for seconds in a tokamak reactor at Princeton Plasma Physics Laboratory in New Jersey. The research grant under consideration, ER54684, uses computer models to aid in understanding and projecting efficacy of heating and current drive sources in the National Spherical Torus Experiment, a tokamak variant, at PPPL. The NSTX experiment explores the physics of very tight aspect ratio, almost spherical tokamaks, aiming at producing steady-state fusion plasmas. The current drive is an integral part of the steady-state concept, maintaining the magnetic geometry in the steady-state tokamak. CompX further developed and applied models for radiofrequency (rf) heating and current drive for applications to NSTX. These models build on a 30 year development of rf ray tracing (the all-frequencies GENRAY code) and higher dimensional Fokker-Planck rf-collisional modeling (the 3D collisional-quasilinear CQL3D code) at CompX. Two mainline current-drive rf modes are proposed for injection into NSTX: (1) electron Bernstein wave (EBW), and (2) high harmonic fast wave (HHFW) modes. Both these current drive systems provide a means for the rf to access the especially high density plasma--termed high beta plasma--compared to the strength of the required magnetic fields. The CompX studies entailed detailed modeling of the EBW to calculate the efficiency of the current drive system, and to determine its range of flexibility for driving current at spatial locations in the plasma cross-section. The ray tracing showed penetration into NSTX bulk plasma, relatively efficient current drive, but a limited ability to produce current over the whole

  11. Experiences of Scientific Thinking in Physics Classrooms

    2018-04-01

    Full Text Available There is a contemporary demand on STEM education to support learning experiences in which students use scientific thinking to solve tasks. Scientific thinking involves domain-specific knowledge and general domain strategies of thinking. The object of interest in this research was the set of students’ experiences of scientific thinking in which they articulate domain-general strategies and domain-specific knowledge to solve physics tasks. Our goal was to characterize the experiences of scientific thinking of two groups of four students engaged in tasks about Newtonian Mechanics. The volunteers were 19 students, 15-17 years old, enrolled in electronics or computer science courses (11th grade of a Brazilian vocational high school at Belo Horizonte/Minas Gerais. All class activities proposed to the students have been regularly used since 2010, therefore, we made no special intervention to conduct the study. Data collection occurred during the classes and involved audio and video recordings of students working in group; field notes; and photographs of students’ notebooks and of the posters they made to conduct oral presentations. The choice of the groups was based on how assiduous the members were. We have transcribed episodes in which we identified experiences of scientific thinking. These transcriptions, the field notes and the photographs were analyzed together, in interaction with each other. Data analysis is based upon John Dewey’s Theory of Experience. Our results show that the experiences of scientific thinking of the two groups were educative experiences, although qualitatively different. This difference was due to the way students interacted with the conditions given to solve the tasks. Additional information is given about the school circumstances in which the study was conducted to allow a better evaluation of results quality.

    The amount and diversity of scientific publications requires a modern management system. By "management" we mean the process of gathering interesting information for the purpose of reading and archiving for quick access in future clinical practice and research activity. In the past, such system required physical existence of a library, either institutional or private. Nowadays in an era dominated by electronic information, it is natural to migrate entire systems to a digital form. In the following paper we describe the structure and functions of an individual electronic library system (IELiS) for the management of scientific publications based on the Google Drive service. Architecture of the system. Architecture system consists of a central element and peripheral devices. Central element of the system is virtual Google Drive provided by Google Inc. Physical elements of the system include: tablet with Android operating system and a personal computer, both with internet access. Required software includes a program to view and edit files in PDF format for mobile devices and another to synchronize the files. Functioning of the system. The first step in creating a system is collection of scientific papers in PDF format and their analysis. This step is performed most frequently on a tablet. At this stage, after being read, the papers are cataloged in a system of folders and subfolders, according to individual demands. During this stage, but not exclusively, the PDF files are annotated by the reader. This allows the user to quickly track down interesting information in review or research process. Modification of the document title is performed at this stage, as well. Second element of the system is creation of a mirror database in the Google Drive virtual memory. Modified and cataloged papers are synchronized with Google Drive. At this stage, a fully functional scientific information electronic library becomes available online. The third element of the system is a

    Highlights, trends, and consensus from the 63 papers submitted to the Scientific Developments theme of the Third International Symposium on Flood Defence (ISFD) are presented. Realizing that absolute protection against flooding can never be guaranteed, trends in flood management have shifted: (1) from flood protection to flood-risk management, (2) from reinforcing structural protection to lowering flood levels, and (3) to sustainable management through integrated problem solving. Improved understanding of watershed responses, climate changes, applications of GIS and remote-sensing technologies, and advanced analytical tools appeared to be the driving forces for renewing flood-risk management strategies. Technical competence in integrating analytical tools to form the basin wide management systems are demonstrated by several large, transnation models. However, analyses from social-economic-environmental points of view are found lag in general. ?? 2006 Taylor & Francis Group.

    Fraudulent business practices, such as those leading to the Enron scandal and the conviction of Bernard Madoff, evoke a strong sense of public outrage. But fraudulent or dishonest actions are not exclusive to the realm of big corporations or to evil individuals without consciences. Dishonest actions are all too prevalent in everyone's daily lives, because people are constantly encountering situations in which they can gain advantages by cutting corners. Whether it's adding a few dollars in value to the stolen items reported on an insurance claim form or dropping outlier data points from a figure to make a paper sound more interesting, dishonesty is part of the human condition. Here, we explore how people rationalize dishonesty, the implications for scientific research, and what can be done to foster a culture of research integrity.

    2003-04-01

    As an American icon, Benjamin Franklin is often portrayed as wise and canny in business and politics, earnestly pursuing and extolling diligence, sensible conduct, pragmatism, and good works. Also legendary are some of his inventions, particularly the lightning rod, bifocals, and an efficient wood-burning stove. The iconic image is misleading in major respects. Today, surprisingly few people appreciate that, in the 18th century, Franklin was greatly esteemed throughout Europe as a scientist (termed then a "natural philosopher.") He was hailed as the "Newton of Electricity." Indeed, until Franklin, electricity seemed more mysterious than had gravity in Newton's time, and lightning was considered the wrath of God. By his own account, Franklin's studies of electricity and many other phenomena were prompted not by practical aims, but by his playful curiosity--which often became obsessive. Also not generally appreciated is the importance of Franklin's scientific reputation in enhancing his efforts to obtain French support for the American Revolution.

    We all learn in elementary school not turn in other people's writing as if it were our own (plagiarism), and in high school science labs not to fake our data. But there are many other practices in scientific publishing that are depressingly common and almost as unethical. At about the 20 percent level authors are deliberately hiding recent work -- by themselves as well as by others -- so as to enhance the apparent novelty of their most recent paper. Some people lie about the dates the data were obtained, to cover up conflicts of interest, or inappropriate use of privileged information. Others will publish the same conference proceeding in multiple volumes, or publish the same result in multiple journals with only trivial additions of data or analysis (self-plagiarism). These shady practices should be roundly condemned and stopped. I will discuss these and other unethical actions I have seen over the years, and steps editors are taking to stop them.

    The scientific value and importance of the Apollo lunar programme is assessed in the light of data obtained both from the lunar surface itself and also from the command modules which orbited above. It is stated that much of the material they returned still awaits a detailed examination and that the cooperative teams set up to handle the lunar material have established new methods and standards of analysis, which are currently revitalising the old science of meteoritics. The new forms of organised research have also been carried over in the rapidly developing subject of planetary science. It is concluded that whatever the motives for launching the Apollo missions, planetary scientists have been in a much better position to understand the Solar System since then. (UK)

We used the bibliographical research, in which it systematized the scientific literature on epistemology and knowledge related to the scientific process and the uncertainties that surround him. The scientific process, though continuously seeks the truth, will not attain perfection, because the researcher deals with the unknown. The science seeks constantly new knowledge and progress with the criticism of the mistakes, seeks the truth, however these are provisional. It is concluded that all scientific knowledge is uncertain.

    The first papers reporting original research results in technical periodicals and proceedings appeared in the late 17th century. Since that time, the typical scientific paper has evolved from a fairly simple document, accessible to a general audience, to a much more complex one, aimed at a specialized audience. The purpose of this article is to give an overview of what the first scientific papers were like and how they evolved to their present form and style. To facilitate this discussion, the scientific paper`s development has arbitrarily been divided into four stages: the origin and formative years of the scientific paper (1665-1765), emergence of scientific papers written for specialized publications (1765-1865), development of the modem scientific paper (1865-1965), and hyperspecialization and computerization of the modem scientific paper (1965-?).

    To present a high school insertion pilot project in post graduate programs (PPG) and discuss the mechanisms for the formation of leaders in science. This study presents a review and pilot project. Bibliographic search occurred in sites of CAPES, MEC, SciELO and library of virtual books from January/ 2014 to February/2015. The pilot is in PPG-Medicine III Translational Surgery/UNIFESP and Pathophysiology and Surgical Sciences / UERJ. The junior undergraduate students (ICj) came from public school and develop scientific activities: scientific meetings, graduation and inclusion in research projects. The evaluation will occur at the end of one year, with the results essays, reports and participation in scientific events. In Brazil, one of the main challenges of education is the high average years of study. The PNPG (2011-2020) shows the insertion of basic education in all PPG. In the Pathophysiology and Surgical Sciences/UERJ there are currently 11 high school students who have followed the scientific meetings and are being prepared for the inclusion in research projects. There was 30% of absence, owing to the high school hours. This result and the experience allow creating future alternatives to enhance the integration project. The leadership in science is formed from a complex relationship between basic education and investment in research. PPG-Medicine III courses follow the vanguard with initiatives focused on scientific and technological development. Thus, projects involving basic education students represent promoter model and environment leaders.

    Energy Technology Data Exchange (ETDEWEB)

    Pearce, Olga Tkachyshyn [Texas A & M Univ., College Station, TX (United States)

    2014-12-01

    The largest supercomputers have millions of independent processors, and concurrency levels are rapidly increasing. For ideal efficiency, developers of the simulations that run on these machines must ensure that computational work is evenly balanced among processors. Assigning work evenly is challenging because many large modern parallel codes simulate behavior of physical systems that evolve over time, and their workloads change over time. Furthermore, the cost of imbalanced load increases with scale because most large-scale scientific simulations today use a Single Program Multiple Data (SPMD) parallel programming model, and an increasing number of processors will wait for the slowest one at the synchronization points. To address load imbalance, many large-scale parallel applications use dynamic load balance algorithms to redistribute work evenly. The research objective of this dissertation is to develop methods to decide when and how to load balance the application, and to balance it effectively and affordably. We measure and evaluate the computational load of the application, and develop strategies to decide when and how to correct the imbalance. Depending on the simulation, a fast, local load balance algorithm may be suitable, or a more sophisticated and expensive algorithm may be required. We developed a model for comparison of load balance algorithms for a specific state of the simulation that enables the selection of a balancing algorithm that will minimize overall runtime.

    Energy Technology Data Exchange (ETDEWEB)

    Bommissetty, Venkat [Materials Research Society, Warrendale, PA (United States)

    2012-11-21

    This symposium aimed to bring together researchers working on quantifying nanoscale carrier transport processes in excitonic solar cells. Excitonic solar cells, including all-organic, hybrid organic-inorganic and dye-sensitized solar cells (DSSCs), offer strong potential for inexpensive and large-area solar energy conversion. Unlike traditional inorganic semiconductor solar cells, where all the charge generation and collection processes are well understood, these excitonic solar cells contain extremely disordered structures with complex interfaces which results in large variations in nanoscale electronic properties and has a strong influence on carrier generation, transport, dissociation and collection. Detailed understanding of these processes is important for fabrication of highly efficient solar cells. Efforts to improve efficiency are underway at a large number of research groups throughout the world focused on inorganic and organic semiconductors, photonics, photophysics, charge transport, nanoscience, ultrafast spectroscopy, photonics, semiconductor processing, device physics, device structures, interface structure etc. Rapid progress in this multidisciplinary area requires strong synergetic efforts among researchers from diverse backgrounds. Such efforts can lead to novel methods for development of new materials with improved photon harvesting and interfacial treatments for improved carrier transport, process optimization to yield ordered nanoscale morphologies with well-defined electronic structures.

    Luiz, Olinda do Carmo

    2007-01-01

    The importance of the communications media in the construction of symbols has been widely acknowledged. Many of the articles on health published in the daily newspapers mention medical studies, sourced from scientific publications focusing on new risks. The disclosure of risk studies in the mass media is also a topic for editorials and articles in scientific journals, focusing the problem of distortions and the appearance of contradictory news items. The purpose of this paper is to explore the meaning and content of disclosing scientific risk studies in large-circulation daily newspapers, analyzing news items published in Brazil and the scientific publications used as their sources during 2000. The "risk" is presented in the scientific research projects as a "black box" in the meaning of Latour, with the news items downplaying scientific disputes and underscoring associations between behavioral habits and the occurrence of diseases, emphasizing individual aspects of the epidemiological approach, to the detriment of the group.

  1. Implicit normativity in scientific advice

    DEFF Research Database (Denmark)

    Folker, Anna Paldam; Andersen, Hanne; Sandøe, Peter

    2008-01-01

    This paper focuses on implicit normative considerations underlying scientific advice-those normative questions, decisions, or issues that scientific advisers and the general public are not fully aware of but that nevertheless have implications for the character of the advice given. Using...... nutritional science as an example, we identify three such implicit normative issues. The first concerns the aim of scientific advice: whether it is about avoiding harm or promoting good. The second concerns the intended beneficiaries of the advice: whether advice should be framed to benefit the society...... as a whole or with special concern for the most vulnerable members of the population. The third consideration involves scientific advisers' attempts to balance the strengths of the scientific evidence with the expected consequences of scientific advice. We hope to promote more explicit discussion...

    reprocessed and yield continuous time series since 2008. The research within SCHOOLS & QUAKES is a consequent continuation of the ALPAACT initiatives. It is coordinated with the ZAMG efforts to keep the routine seismological work on a high scientific standard. Three polytechnic schools in Vienna and the southern Vienna Basin (Mödling and Wiener Neustadt) take part in SCHOOLS & QUAKES. So-called school seismometers as well as high performance short period stations have been installed at these locations. In addition to routine maintenance and site optimization of the seismic stations, scholars and teachers of these schools contribute to research by their unprejudiced approach to interactive event detection and travel time picking as well as by their expertise in electronics, informatics, and civil engineering. The development of low cost short period stations which meet the requirements of medium to high noise locations, or the generation of shake maps and their conversion into maps of potential source locations are work in progress in cooperation with graduate students.

  11. Revista de Saúde Pública in scientific publications on Violence and Health (1967-2015

    Directory of Open Access Journals (Sweden)

    Lilia Blima Schraiber

    Full Text Available ABSTRACT This article retrieved the publications from the Revista de Saúde Pública journal (from 1967 to 2015 on violence and health, on the SciELO and PubMed bases, by searching for the terms “violence”, “suicide”, “aggression”, “bullying”, and “external causes”, registered in any part of the text. We found 130 articles (the first one published in 1974. We observed: increase of publications over time, with decrease in the last five years; similar production volume in lethal and non-lethal violence; later publication of the latter; few studies in qualitative research; mostly descriptive production; and visualization of the problem more by the acts than by contexts or motivations and aggressors. Social markers were little approached, appearing, from largest to smallest frequency, social class, gender, race/ethnicity, and generation. Human rights were little used and only recently used as analytical framework, connected more to gender than to social class. Although Revista de Saúde Pública has registered the theme in its publications, consolidating it as scientific production line, there is still great explanatory theoretical rarefaction and little intersectionality between violence, social inequalities, and human rights.

  12. Self-care under the perspective of Occupational Therapy: analysis of scientific production

    Directory of Open Access Journals (Sweden)

    Regina Célia Titotto Castanharo

    2014-04-01

    Full Text Available This is an exploratory descriptive study aiming to explain how self-care has been addressed by Occupational Therapy (OT. Data collection was carried out by consulting LILACS, SciELO databases and national journals of Occupational Therapy. From 1994 to 2012, twelve articles published by occupational therapists were selected considering the following keywords on abstracts or full texts: occupational therapy, self-care, daily activities or daily life activities. The results were submitted to integrative review and thematic analysis. The categories evidenced were self-care and activities of daily life; autonomy and independence for self-care; and intervention of OT favoring self-care by the individual. The results showed different dimensions of self-care when associated with the individual and private autonomy as well as with professional interdisciplinary practices of OT. The intervention in this area is directed to human performance in the cycles of life, faced with situations of vulnerability, such as disease and social exclusion. Adaptations, modifications, assistive technology resources and/or functional rehabilitation are used to promote the independence of individuals, favoring autonomy and recovery routines. We observed similarities between the conceptions of self-care found in the scientific production of OT and in the Orem’s concepts (1971-2001. In general, health professionals can achieve benefits to the systematization of knowledge that underlie their practice when they articulate them with the knowledge systematized by other areas.

Has identified various effects such as mood disorders and sleep disorders, hostility, isolation, insecurity, among others. To describe and analyze scientific evidence published on workplace violence in studies in Latin American countries between 2009 and 2014. A descriptive and quantitative study. A search was made on the basis of Academic Search Complete (EBSCOhost) Academic Source Premier, PSICODOC, Scielo.org, JSTOR and SCOPUS. And indexed empirical studies were considered. We worked with 46 selected articles. The studies showed a higher amount of psychological violence at work, with a potential risk in women and health professionals. Also, the analysis categories were the most reported behaviors that express violence, health implications and facilitators. The literature on the study of workplace violence in Latin America is recent. Items are descriptive, interpretative studies with insufficient or analytical nature. Health personnel, particularly women, have conditions of vulnerability, with relevance with regard to sexual harassment, wage inequality and bullying.

  11. Scientific Publication Ethics

    Directory of Open Access Journals (Sweden)

    Osman İnci

    2015-06-01

    Full Text Available Science based on consciousness of responsibility and principles of trust puts academics under an obligation to act according to the values and principles, ethical attitudes and standards of behaviour. A quest for perfectness, to observe truth and show respect for the dignity and value of each individual should be a fundamental principle. In this context, academic freedom and autonomy, academic integrity,  responsibility and accountabily, respect for others, the protection of the fundamental rights and competence are among the core values of academic merit. Science is not possible without ethics. Protection of academic value is essential for an academic publication. It is also fundamental that academics should not behave contrary to the ethics values. It is assumed that academic studies are conducted honestly, based on true foundations, that the research data are collected according to the correct methods, accurate statistics are used and results are reported accordingly. It is also assumed that professional standards are carried out in software presentation and share of results. The exceptional methods in academical publications should be classified as those carried out intentionally, aiming to mislead the related studies and the others to be distinguished from the ones carried out by some ignorances and various innocent facts. The most serious infraction of the ethical rules and standards is the ‘academic misappropriation’. Among all, the most crucial one is the academic plagiarism, which is transferring the production of some other person under one’s own name or stealing away the work of other persons. Creating some not-existing data and results, and fabrication is inventing some information just by sitting at the table. Changing the datas and results without scientific reasoning, and falsification is accepted as another and the third kind of misappropriation (FTP.

  12. Does Scientific Evidence for the Use of Natural Products in the Treatment of Oral Candidiasis Exist? A Systematic Review

    Directory of Open Access Journals (Sweden)

    Gabriela Lacet Silva Ferreira

    2015-01-01

    Full Text Available In view of the limitations of antifungal agents used in the treatment of oral candidiasis and the wide variety of natural products that have been studied as treatment of this disease, this systematic literature review proposed to evaluate whether scientific evidence attesting to the efficacy of natural products in the treatment of this disease exists. A systematic search in PubMed, MEDLINE, SciELO, Lilacs, and Cochrane Library databases was accomplished using the associations among the keywords Candida albicans, phytotherapy, biological products, denture stomatitis, and oral candidiasis in both English and Portuguese. Four independent observers evaluated the methodological quality of the resulting articles. Three studies were included for detailed analysis and evaluated according to the analysis protocol based on the CONSORT (Consolidated Standards of Reporting Trials 2010 statement. The tested products were different in all studies. Two studies mentioned random samples, but no study described the sample allocation. No study mentioned sample calculations, a prior pilot study, or examiner calibration, and only one trial reported sample losses. Differences between the tested products and the methodological designs among these studies did not allow the existence of scientific evidence related to the effectiveness of these products for the proposed subjects to be confirmed.

  14. Electronic Publishing or Electronic Information Handling?

    Science.gov (United States)

    Heck, A.

    The current dramatic evolution in information technology is bringing major modifications in the way scientists communicate. The concept of 'electronic publishing' is too restrictive and has often different, sometimes conflicting, interpretations. It is thus giving way to the broader notion of 'electronic information handling' encompassing the diverse types of information, the different media, as well as the various communication methodologies and technologies. New problems and challenges result also from this new information culture, especially on legal, ethical, and educational grounds. The procedures for validating 'published material' and for evaluating scientific activities will have to be adjusted too. 'Fluid' information is becoming a common concept. Electronic publishing cannot be conceived without link to knowledge bases nor without intelligent information retrieval tools.

  16. Hard electronics; Hard electronics

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    1997-03-01

    Hard material technologies were surveyed to establish the hard electronic technology which offers superior characteristics under hard operational or environmental conditions as compared with conventional Si devices. The following technologies were separately surveyed: (1) The device and integration technologies of wide gap hard semiconductors such as SiC, diamond and nitride, (2) The technology of hard semiconductor devices for vacuum micro- electronics technology, and (3) The technology of hard new material devices for oxides. The formation technology of oxide thin films made remarkable progress after discovery of oxide superconductor materials, resulting in development of an atomic layer growth method and mist deposition method. This leading research is expected to solve such issues difficult to be easily realized by current Si technology as high-power, high-frequency and low-loss devices in power electronics, high temperature-proof and radiation-proof devices in ultimate electronics, and high-speed and dense- integrated devices in information electronics. 432 refs., 136 figs., 15 tabs.

    A system capable of performing radiography using a beam of electrons. Diffuser means receive a beam of electrons and diffuse the electrons before they enter first matching quadrupoles where the diffused electrons are focused prior to the diffused electrons entering an object. First imaging quadrupoles receive the focused diffused electrons after the focused diffused electrons have been scattered by the object for focusing the scattered electrons. Collimator means receive the scattered electrons and remove scattered electrons that have scattered to large angles. Second imaging quadrupoles receive the collimated scattered electrons and refocus the collimated scattered electrons and map the focused collimated scattered electrons to transverse locations on an image plane representative of the electrons' positions in the object.

    Although an increasing amount of middleware has emerged in the last few years to achieve remote data access, distributed job execution, and data management, orchestrating these technologies with minimal overhead still remains a difficult task for scientists. Scientific workflow systems improve this situation by creating interfaces to a variety of technologies and automating the execution and monitoring of the workflows. Workflow systems provide domain-independent customizable interfaces and tools that combine different tools and technologies along with efficient methods for using them. As simulations and experiments move into the petascale regime, the orchestration of long running data and compute intensive tasks is becoming a major requirement for the successful steering and completion of scientific investigations. A scientific workflow is the process of combining data and processes into a configurable, structured set of steps that implement semi-automated computational solutions of a scientific problem. Kepler is a cross-project collaboration, co-founded by the SciDAC Scientific Data Management (SDM) Center, whose purpose is to develop a domain-independent scientific workflow system. It provides a workflow environment in which scientists design and execute scientific workflows by specifying the desired sequence of computational actions and the appropriate data flow, including required data transformations, between these steps. Currently deployed workflows range from local analytical pipelines to distributed, high-performance and high-throughput applications, which can be both data- and compute-intensive. The scientific workflow approach offers a number of advantages over traditional scripting-based approaches, including ease of configuration, improved reusability and maintenance of workflows and components (called actors), automated provenance management, 'smart' re-running of different versions of workflow instances, on-the-fly updateable parameters, monitoring

    2013-01-01

    From the hypothesis that the development of scientific papers, mainly in interdisciplinary areas such as Health Informatics, may bring difficulties to the author, as had its communicative efficacy decreased or compromising their approval for publication; we aim to make considerations on the main items to good players making this kind of text. The scientific writing has peculiarities that must be taken into consideration when it writes: general characteristics, such as simplicity and objectivity, and characteristics of each area of knowledge, such as terminology, formatting and standardization. The research methodology adopted is bibliographical. The information was based on literature review and the authors' experience, teachers and assessors of scientific methodology in peer review publications in the area. As a result, we designed a checklist of items to be checked before submission of a paper to a scientific publication vehicle in order to contribute to the promotion of research, facilitating the publication and increase its capacity in this important area of knowledge.

    The U.S. Environmental Protection Agency (EPA) issued its draft scientific integrity policy on 5 August. The draft policy addresses scientific ethical standards, communications with the public, the use of advisory committees and peer review, and professional development. The draft policy was developed by an ad hoc group of EPA senior staff and scientists in response to a December 2010 memorandum on scientific integrity from the White House Office of Science and Technology Policy. The agency is accepting public comments on the draft through 6 September; comments should be sent to osa.staff@epa.gov.

    Scientific Computing was one of the first every applications for parallel and distributed computation. To this date, scientific applications remain some of the most compute intensive, and have inspired creation of petaflop compute infrastructure such as the Oak Ridge Jaguar and Los Alamos RoadRunner. Large dedicated hardware infrastructure has become both a blessing and a curse to the scientific community. Scientists are interested in cloud computing for much the same reason as businesses and other professionals. The hardware is provided, maintained, and administrated by a third party. Software abstraction and virtualization provide reliability, and fault tolerance. Graduated fees allow for multi-scale prototyping and execution. Cloud computing resources are only a few clicks away, and by far the easiest high performance distributed platform to gain access to. There may still be dedicated infrastructure for ultra-scale science, but the cloud can easily play a major part of the scientific computing initiative.

    Recent National Institutes of Health changes have focused attention on the potential scientific impact of research projects. Research with the excellent potential to change subsequent science or health care practice may have high scientific impact. Only rigorous studies that address highly significant problems can generate change. Studies with high impact may stimulate new research approaches by changing understanding of a phenomenon, informing theory development, or creating new research methods that allow a field of science to move forward. Research with high impact can transition health care to more effective and efficient approaches. Studies with high impact may propel new policy developments. Research with high scientific impact typically has both immediate and sustained influence on the field of study. The article includes ideas to articulate potential scientific impact in grant applications as well as possible dissemination strategies to enlarge the impact of completed projects.

  12. Novel electron gas systems

    International Nuclear Information System (INIS)

    Senatore, G.; Rapisarda, F.; Conti, S.

    1998-01-01

    We review recent progress on the physics of electrons in the bilayered electron gas, relevant to coupled quantum wells in GaAs/AIGaAs heterostructures. First we focus on the phase diagram of a symmetric bilayer at T = B = 0, obtained by diffusion Monte Carlo (DMC) simulations. It is found that inter-layer correlations stabilize crystalline structures at intermediate inter-layer separation, while favoring a liquid phase at smaller distance. Also, the available DMC evidence is in contrast with the recently (Hartree-Fock) predicted total charge transfer (TCT), whereby all the electron spontaneously jump in one layer. In fact, one can show that such a TCT state is never stable in the ideal bilayer with no tunneling. We finally comment on ongoing DMC investigations on the electron-hole bilayer, where excitonic condensation is expected to take place. (Copyright (1998) World Scientific Publishing Co. Pte. Ltd)

  17. Scientific Ethics: A New Approach.

    Science.gov (United States)

    Menapace, Marcello

    2018-06-04

    Science is an activity of the human intellect and as such has ethical implications that should be reviewed and taken into account. Although science and ethics have conventionally been considered different, it is herewith proposed that they are essentially similar. The proposal set henceforth is to create a new ethics rooted in science: scientific ethics. Science has firm axiological foundations and searches for truth (as a value, axiology) and knowledge (epistemology). Hence, science cannot be value neutral. Looking at standard scientific principles, it is possible to construct a scientific ethic (that is, an ethical framework based on scientific methods and rules), which can be applied to all sciences. These intellectual standards include the search for truth (honesty and its derivatives), human dignity (and by reflection the dignity of all animals) and respect for life. Through these it is thence achievable to draft a foundation of a ethics based purely on science and applicable beyond the confines of science. A few applications of these will be presented. Scientific ethics can have vast applications in other fields even in non scientific ones.

  19. Network effects on scientific collaborations.

    Directory of Open Access Journals (Sweden)

    Full Text Available BACKGROUND: The analysis of co-authorship network aims at exploring the impact of network structure on the outcome of scientific collaborations and research publications. However, little is known about what network properties are associated with authors who have increased number of joint publications and are being cited highly. METHODOLOGY/PRINCIPAL FINDINGS: Measures of social network analysis, for example network centrality and tie strength, have been utilized extensively in current co-authorship literature to explore different behavioural patterns of co-authorship networks. Using three SNA measures (i.e., degree centrality, closeness centrality and betweenness centrality, we explore scientific collaboration networks to understand factors influencing performance (i.e., citation count and formation (tie strength between authors of such networks. A citation count is the number of times an article is cited by other articles. We use co-authorship dataset of the research field of 'steel structure' for the year 2005 to 2009. To measure the strength of scientific collaboration between two authors, we consider the number of articles co-authored by them. In this study, we examine how citation count of a scientific publication is influenced by different centrality measures of its co-author(s in a co-authorship network. We further analyze the impact of the network positions of authors on the strength of their scientific collaborations. We use both correlation and regression methods for data analysis leading to statistical validation. We identify that citation count of a research article is positively correlated with the degree centrality and betweenness centrality values of its co-author(s. Also, we reveal that degree centrality and betweenness centrality values of authors in a co-authorship network are positively correlated with the strength of their scientific collaborations. CONCLUSIONS/SIGNIFICANCE: Authors' network positions in co

    This article explores the capacity of Latin America in the generation of scientific knowledge and its visibility at the global level. The novelty of the contribution lies in the decomposition of leadership, plus its combination with the results of performance indicators. We compare the normalized citation of all output against the leading output, as well as scientific excellence (Chinchilla, et al. 2016a; 2016b), technological impact and the trends in collaboration types and normalized citation. The main goal is to determine to what extent the main Latin American producers of scientific output depend on collaboration to heighten research performance in terms of citation; or to the contrary, whether there is enough autonomy and capacity to leverage its competitiveness through the design of research and development agendas. To the best of our knowledge this is the first study adopting this approach at the country level within the field of N&N. (Author)

    Biomedical ontologies have been very successful in structuring knowledge for many different applications, receiving widespread praise for their utility and potential. Yet, the role of computational ontologies in scientific research, as opposed to knowledge management applications, has not been extensively discussed. We aim to stimulate further discussion on the advantages and challenges presented by biomedical ontologies from a scientific perspective. We review various aspects of biomedical ontologies going beyond their practical successes, and focus on some key scientific questions in two ways. First, we analyze and discuss current approaches to improve biomedical ontologies that are based largely on classical, Aristotelian ontological models of reality. Second, we raise various open questions about biomedical ontologies that require further research, analyzing in more detail those related to visual reasoning and spatial ontologies. We outline significant scientific issues that biomedical ontologies should consider, beyond current efforts of building practical consensus between them. For spatial ontologies, we suggest an approach for building "morphospatial" taxonomies, as an example that could stimulate research on fundamental open issues for biomedical ontologies. Analysis of a large number of problems with biomedical ontologies suggests that the field is very much open to alternative interpretations of current work, and in need of scientific debate and discussion that can lead to new ideas and research directions.

  7. The scientific status of fusion

    International Nuclear Information System (INIS)

    Crandall, D.H.

    1989-01-01

    The development of fusion energy has been a large-scale scientific undertaking of broad interest. The magnetic plasma containment in tokamaks and the laser-drive ignition of microfusion capsules appear to be scientifically feasible sources of energy. These concepts are bounded by questions of required intensity in magnetid field and plasma currents or in drive energy and, for both concepts, by issues of plasma stability and energy transport. The basic concept and the current scientific issues are described for magnetic fusion and for the interesting, but likely infeasible, muon-catalyzed fusion concept. Inertial fusion is mentioned, qualitatively, to complete the context. For magnetic fusion, the required net energy production within the plasma may be accomplished soon, but the more useful goal of self-sustained plasma ignition requires a new device of somewhat uncertain (factor of 2) cost and size.

    Murphy, M F; Goodnough, L T

    2015-08-01

    Patient blood management is an increasingly used term to describe an evidence-based, multidisciplinary approach to optimising the care of patients who might need transfusion. It encompasses measures to avoid transfusion such as anaemia management without transfusion, cell salvage and the use of anti-fibrinolytic drugs to reduce bleeding as well as restrictive transfusion. It ensures that patients receive the optimal treatment, and that avoidable, inappropriate use of blood and blood components is reduced. This paper provides an overview of the scientific basis for patient blood management with a focus on the increasing evidence for restrictive rather than liberal transfusion practice and the use of electronic blood ordering and decision support to facilitate its implementation.

    Human performance can get degraded due to boredom, distraction and fatigue in vision-related tasks such as measurement, counting etc. Vision based techniques are increasingly being employed in many scientific and engineering applications. Notable advances in this field are emerging from continuing improvements in the fields of sensors and related technologies, and advances in computer hardware and software. Automation utilizing vision-based systems can perform repetitive tasks faster and more accurately, with greater consistency over time than humans. Electronics and Instrumentation Services Division has developed vision-based systems for several applications to perform tasks such as precision alignment, biometric access control, measurement, counting etc. This paper describes in brief four such applications.

    2013-12-01

    The scientist's primary incentive is publication. In the present culture, open practices do not increase chances of publication, and they often require additional work. Practicing the abstract scientific values of openness and reproducibility thus requires behaviors in addition to those relevant for the primary, concrete rewards. When in conflict, concrete rewards are likely to dominate over abstract ones. As a consequence, the reward structure for scientists does not encourage openness and reproducibility. This can be changed by nudging incentives to align scientific practices with scientific values. Science will benefit by creating and connecting technologies that nudge incentives while supporting and improving the scientific workflow. For example, it should be as easy to search the research literature for my topic as it is to search the Internet to find hilarious videos of cats falling off of furniture. I will introduce the Center for Open Science (http://centerforopenscience.org/) and efforts to improve openness and reproducibility such as http://openscienceframework.org/. There will be no cats.

The streamlines of the seventeen magazines on four bibliometric indexes (SCIENCE INDEX, five-year impact factor RISC given the translated version without self-citations, h-index over 10 years and Herfindahl index, which are used in the scientific electronic library elibrary.ru was used as initial data. The statement of the problem refers to multi-criteria decision-making problems. Ranking the journals in these indexes are different from each other because bibliometric indicators account different aspects of the journals. The classical approach to thisproblems solution is based on generalized criterion building in the form of an additive convolution. However, this approach requires adherence to a number of regular conditions that may not always be performed when the practical problems solution. The reductionspossibility of the considered formulation in the form of multi-criteria decision-making tasks to the problem of collective choice. The aggregated ratings of the reporting journals are calculated by using the three social choice rules – Board procedure, Copeland procedures and Kemeny median heuristic procedures. On the basis of Spearman's rank correlation determined the quantitative evaluation of the degree of intimacy built in magazines. In particular, calculated on the basis of procedure, Board and Kemeny median aggregate ratings reporting in the logs coincided. The results showed that the constructed ordering of journals on the basis of social choice rules are in good agreement with the scientific electronic library (eLIBRARY bibliometric indicators.

    The Scientific Assistant Virtual Laboratory (SAVL) is a scientific discovery environment, an interactive simulated virtual laboratory, for learning physics and mathematics. The purpose of this computer-assisted intervention is to improve middle and high school student interest, insight and scores in physics and mathematics. SAVL develops scientific and mathematical imagination in a visual, symbolic, and experimental simulation environment. It directly addresses the issues of scientific and technological competency by providing critical thinking training through integrated modules. This on-going research provides a virtual laboratory environment in which the student directs the building of the experiment rather than observing a packaged simulation. SAVL: * Engages the persistent interest of young minds in physics and math by visually linking simulation objects and events with mathematical relations. * Teaches integrated concepts by the hands-on exploration and focused visualization of classic physics experiments within software. * Systematically and uniformly assesses and scores students by their ability to answer their own questions within the context of a Master Question Network. We will demonstrate how the Master Question Network uses polymorphic interfaces and C# lambda expressions to manage simulation objects.

  13. Scientific knowledge and modern prospecting

    Neuerburg, G.J.

    1985-01-01

    Modern prospecting is the systematic search for specified and generally ill-exposed components of the Earth's crust known as ore. This prospecting depends entirely on reliable, or scientific knowledge for guidance and for recognition of the search objects. Improvement in prospecting results from additions and refinements to scientific knowledge. Scientific knowledge is an ordered distillation of observations too numerous and too complex in themselves for easy understanding and for effective management. The ordering of these observations is accomplished by an evolutionary hierarchy of abstractions. These abstractions employ simplified descriptions consisting of characterization by selected properties, sampling to represent much larger parts of a phenomenon, generalized mappings of patterns of geometrical and numerical relations among properties, and explanation (theory) of these patterns as functional relations among the selected properties. Each abstraction is predicated on the mode of abstraction anticipated for the next higher level, so that research is a deductive process in which the highest level, theory, is indispensible for the growth and refinement of scientific knowledge, and therefore of prospecting methodology. ?? 1985 Springer-Verlag.

  19. Promoting Science Learning and Scientific Identification through Contemporary Scientific Investigations

    Science.gov (United States)

    Van Horne, Katie

    This dissertation investigates the implementation issues and the educational opportunities associated with "taking the practice turn" in science education. This pedagogical shift focuses instructional experiences on engaging students in the epistemic practices of science both to learn the core ideas of the disciplines, as well as to gain an understanding of and personal connection to the scientific enterprise. In Chapter 2, I examine the teacher-researcher co-design collaboration that supported the classroom implementation of a year-long, project-based biology curriculum that was under development. This study explores the dilemmas that arose when teachers implemented a new intervention and how the dilemmas arose and were managed throughout the collaboration of researchers and teachers and between the teachers. In the design-based research of Chapter 3, I demonstrate how students' engagement in epistemic practices in contemporary science investigations supported their conceptual development about genetics. The analysis shows how this involved a complex interaction between the scientific, school and community practices in students' lives and how through varied participation in the practices students come to write about and recognize how contemporary investigations can give them leverage for science-based action outside of the school setting. Finally, Chapter 4 explores the characteristics of learning environments for supporting the development of scientific practice-linked identities. Specific features of the learning environment---access to the intellectual work of the domain, authentic roles and accountability, space to make meaningful contributions in relation to personal interests, and practice-linked identity resources that arose from interactions in the learning setting---supported learners in stabilizing practice-linked science identities through their engagement in contemporary scientific practices. This set of studies shows that providing students with the

  1. Deathcore, creativity, and scientific thinking

    Angeler, David G.; Sundstrom, Shana M.; Allen, Craig R.

    2016-01-01

    BackgroundMajor scientific breakthroughs are generally the result of materializing creative ideas, the result of an inductive process that sometimes spontaneously and unexpectedly generates a link between thoughts and/or objects that did not exist before. Creativity is the cornerstone of scientific thinking, but scientists in academia are judged by metrics of quantification that often leave little room for creative thinking. In many scientific fields, reductionist approaches are rewarded and new ideas viewed skeptically. As a result, scientific inquiry is often confined to narrow but safe disciplinary ivory towers, effectively preventing profoundly creative explorations that could yield unexpected benefits.New informationThis paper argues how apparently unrelated fields specifically music and belief systems can be combined in a provocative allegory to provide novel perspectives regarding patterns in nature, thereby potentially inspiring innovation in the natural, social and other sciences. The merger between basic human tensions such as those embodied by religion and music, for example the heavy metal genre of deathcore, may be perceived as controversial, challenging, and uncomfortable. However, it is an example of moving the thinking process out of unconsciously established comfort zones, through the connection of apparently unrelated entities. We argue that music, as an auditory art form, has the potential to enlighten and boost creative thinking in science. Metal, as a fast evolving and diversifying extreme form of musical art, may be particularly suitable to trigger surprising associations in scientific inquiry. This may pave the way for dealing with questions about what we don´t know that we don´t know in a fast-changing planet.

    Electron holography using a coherent electron wave is a promising technique for high-resolution visualization of electromagnetic fields in and around objects. The capability of electron holography has been enhanced by the development of new technologies and has thus become an even more powerful tool for exploring scientific frontiers. This review introduces these technologies including split-illumination electron holography and vector-field electron tomography. Split-illumination electron holography, which uses separated coherent waves, overcomes the limits imposed by the lateral coherence requirement for electron waves in electron holography. Areas that are difficult to observe using conventional electron holography are now observable. Exemplified applications include observing a singular magnetic domain wall in electrical steel sheets, local magnetizations at anti-phase boundaries, and electrostatic potentials in metal-oxide-semiconductor field-effect transistors. Vector-field electron tomography can be used to visualize magnetic vectors in three dimensions. Two components of the vectors are reconstructed using dual-axis tomography, and the remaining one is calculated using div B   =  0. A high-voltage electron microscope can be used to achieve precise magnetic reconstruction. For example, magnetic vortices have been visualized using a 1 MV holography electron microscope.

  4. Software Defects, Scientific Computation and the Scientific Method

    CERN Multimedia

    CERN. Geneva

    2011-01-01

    Computation has rapidly grown in the last 50 years so that in many scientific areas it is the dominant partner in the practice of science. Unfortunately, unlike the experimental sciences, it does not adhere well to the principles of the scientific method as espoused by, for example, the philosopher Karl Popper. Such principles are built around the notions of deniability and reproducibility. Although much research effort has been spent on measuring the density of software defects, much less has been spent on the more difficult problem of measuring their effect on the output of a program. This talk explores these issues with numerous examples suggesting how this situation might be improved to match the demands of modern science. Finally it develops a theoretical model based on an amalgam of statistical mechanics and Hartley/Shannon information theory which suggests that software systems have strong implementation independent behaviour and supports the widely observed phenomenon that defects clust...

  5. Electron/electron acoustic instability

    International Nuclear Information System (INIS)

    Gary, S.P.

    1987-01-01

    The electron acoustic wave becomes a normal mode of an unmagnetized collisionless plasma in the presence of two electron components with similar densities, but strongly disparate temperatures. The characteristic frequency of this mode is the plasma frequency of the cooler electron component. If these two electron components have a relative drift speed several times the thermal speed of the cooler component, the electron/electron acoustic instability may arise. This paper describes the parametric dependences of the threshold drift speed and maximum growth rate of this instability, and compares these with the same properties of the electron/ion acoustic instability. Under the condition of zero current, the electron/ion acoustic instability typically has the lower threshold drift speed, so that observation of the electron/electron acoustic instability is a strong indication of the presence of an electrical current in the plasma

    Full Text Available This study evidences the intersection between science education and communication in the perspective of the popularization of sciences based on the evidence produced in a specific column of a large circulation newspaper of the city of Teresina / PI. The discussions were based on the analysis of content carried out in the context of science classes in a school of basic education with elementary students, where journalistic texts were used with diverse themes that involved science and daily life in order to understand the interpretation of texts And the relationship with the context of scientific dissemination and citizenship. The analysis of the content was used and the answers were stratified into categories of conceptual nature and application of the themes. The analyses show that the texts of scientific dissemination have a contribution in relation to the popularization of Sciences, fomentation to the debate in the classroom, didactic increment in the classes of sciences, in spite of their insertion still incipient in the context of science education. However, the results of the research denote the difficulty faced by the students in understanding the text of dissemination in their conceptual comprehension and resolution of daily problems, as well as the distance between the context of the sciences in their theoretical scope and their presentation in everyday situations, Despite this, the texts of divulgation corroborated as an important way of real insertion in the process of scientific literacy and promotion of citizenship.

    El-Demerdash, Aref M.

    The national goals of clean air, clean water, and healthy ecosystems are a few of the primary forces that drive the need for better environmental monitoring. As we approach the end of the 1990s, the environmental questions at regional to global scales are being redefined and refined in the light of developments in environmental understanding and technological capability. Research in the use of scientific imaging data for the study of the environment is urgently needed in order to explore the possibilities of utilizing emerging new technologies. The objective of this research proposal is to demonstrate the usability of a wealth of new technology made available in the last decade to providing a better understanding of environmental problems. Research is focused in two imaging techniques macro and micro imaging. Several examples of applications of scientific imaging in research in the field of environmental toxicology were presented. This was achieved on two scales, micro and macro imaging. On the micro level four specific examples were covered. First, the effect of utilizing scanning electron microscopy as an imaging tool in enhancing taxa identification when studying diatoms was presented. Second, scanning electron microscopy combined with energy dispersive x-ray analyzer were demonstrated as a valuable and effective tool for identifying and analyzing household dust samples. Third, electronic autoradiography combined with FT-IR microscopy were used to study the distribution pattern of [14C]-Malathion in rats as a result of dermal exposure. The results of the autoradiography made on skin sections of the application site revealed the presence of [ 14C]-activity in the first region of the skin. These results were evidenced by FT-IR microscopy. The obtained results suggest that the penetration of Malathion into the skin and other tissues is vehicle and dose dependent. The results also suggest the use of FT-IR microscopy imaging for monitoring the disposition of

These are juxtaposed to social-scientific, power-sensitive models (Elias, Bourdieu, Merton). The (surplus) value of scientific communication can be variously understood: either as inherent surplus values in the sense of potential effects of stimulation, synergy, critique, quality control; or as symbolic surplus value in the sense of symbolic capital (Bourdi...

  19. Cyber-Enabled Scientific Discovery

    International Nuclear Information System (INIS)

    Chan, Tony; Jameson, Leland

    2007-01-01

    It is often said that numerical simulation is third in the group of three ways to explore modern science: theory, experiment and simulation. Carefully executed modern numerical simulations can, however, be considered at least as relevant as experiment and theory. In comparison to physical experimentation, with numerical simulation one has the numerically simulated values of every field variable at every grid point in space and time. In comparison to theory, with numerical simulation one can explore sets of very complex non-linear equations such as the Einstein equations that are very difficult to investigate theoretically. Cyber-enabled scientific discovery is not just about numerical simulation but about every possible issue related to scientific discovery by utilizing cyberinfrastructure such as the analysis and storage of large data sets, the creation of tools that can be used by broad classes of researchers and, above all, the education and training of a cyber-literate workforce

  20. Tracing Young Children's Scientific Reasoning

    Science.gov (United States)

    Tytler, Russell; Peterson, Suzanne

    2003-08-01

    This paper explores the scientific reasoning of 14 children across their first two years of primary school. Children's view of experimentation, their approach to exploration, and their negotiation of competing knowledge claims, are interpreted in terms of categories of epistemological reasoning. Children's epistemological reasoning is distinguished from their ability to control variables. While individual children differ substantially, they show a relatively steady growth in their reasoning, with some contextual variation. A number of these children are reasoning at a level well in advance of curriculum expectations, and it is argued that current recommended practice in primary science needs to be rethought. The data is used to explore the relationship between reasoning and knowledge, and to argue that the generation and exploration of ideas must be the key driver of scientific activity in the primary school.

  1. Genealogical Trees of Scientific Papers.

    Science.gov (United States)

    Waumans, Michaël Charles; Bersini, Hugues

    2016-01-01

    Many results have been obtained when studying scientific papers citations databases in a network perspective. Articles can be ranked according to their current in-degree and their future popularity or citation counts can even be predicted. The dynamical properties of such networks and the observation of the time evolution of their nodes started more recently. This work adopts an evolutionary perspective and proposes an original algorithm for the construction of genealogical trees of scientific papers on the basis of their citation count evolution in time. The fitness of a paper now amounts to its in-degree growing trend and a "dying" paper will suddenly see this trend declining in time. It will give birth and be taken over by some of its most prevalent citing "offspring". Practically, this might be used to trace the successive published milestones of a research field.

A sample of the retrieved hits was analyzed with regard to how various publication attributes correlated with the scientific quality...... of the content and whether this information could be employed to harvest, filter, and rank Web publications. The attributes analyzed were inlinks, outlinks, bibliographic references, file format, language, search engine overlap, structural position (according to site structure), and the occurrence of various...... types of metadata. As could be expected, the ranked output differs between the three search engines. Apparently, this is caused by differences in ranking algorithms rather than the databases themselves. In fact, because scientific Web content in this subject domain receives few inlinks, both Alta...

  5. [Scientific concepts in clinical medicine].

    Science.gov (United States)

    Rogler, G

    2003-11-28

    The understanding of the scientific basis and the theory of knowledge are surprisingly heterogeneous in practical and clinical medicine. It is frequently influenced or based on the philosophical theory of critical rationalism founded by Sir Karl Popper. Because the theory of knowledge and the understanding of scientific truth is the central basis for cautious and good clinical practise it is necessary to discuss both points to avoid unscientific auto-immunisation against critique in a type of medicine that regards herself as science-based. Evidence-based medicine would not be possible without interpretation and explanation of existing data into the individual treatment context. Besides an inductive or deductive logic the historical and situative side-conditions of the gathering of knowledge and of experiments are of central importance for their interpretation and their relevance in clinical practice. This historical and situative context warrants reflection but must also be paid attention to in the reflections on medical ethics.

  6. Electronic emission and electron guns

    International Nuclear Information System (INIS)

    Roy, Amitava

    2010-01-01

    This paper reviews the process of electron emission from metal surface. Although electrons move freely in conductors like metals, they normally do not leave the metal without some manipulation. In fact, heating and bombardment are the two primary ways in which electrons are emitted through the use of a heating element behind the cathode (termed thermionic emission) or as a result of bombardment with a beam of electrons, ions, or metastable atoms (termed secondary emission). Another important emission mechanism called Explosive Electron Emission (EEE) is also often used in various High Voltage Pulse Power Systems to generate very high current (few hundreds of kA) pulsed electron beams. The electron gun is the device in that it shoots off a continuous (or pulsed) stream of electrons. A brief idea about the evolution of the electron gun components and their basis of functioning are also discussed. (author)

    In order to calculate the electron trajectory of 200 kV self-shielded electron accelerator, the electric field is calculated with a TRAJ program. In this program, following electron track mash points one by one, the electron beam trajectories are calculated. Knowing the effect of grid voltage on electron optics and gaining grid voltage focusing effect in the various energy grades, the authors have gained scientific basis for adjusting grid voltage, and also accumulated a wealth of experience for designing self-shielded electron accelerator or electron curtain in future

    In HEP, scientific research is performed by large collaborations of organizations and individuals. The logbook of a scientific collaboration is an important part of the collaboration record. Often it contains experimental data. At Fermi National Accelerator Laboratory (FNAL), we developed an Electronic Collaboration Logbook (ECL) application, which is used by about 20 different collaborations, experiments and groups at FNAL. The ECL is the latest iteration of the project formerly known as the Control Room Logbook (CRL). We have been working on mobile (IOS and Android) clients for the ECL. We will present the history, current status and future plans of the project, as well as design, implementation and support solutions made by the project.

    The number of Tunisian women conducting scientific research is comparable to that of countries where educating girls has been going on much longer. Although women play an increasingly important role in the field of research, they rarely hold positions of responsibility. Enormous similarities exist between the degree of integration of Tunisian women in science and technology and that of developed countries. Since independence and the removal of discrimination between girls and boys, Tunisian women have been catching up very quickly.

    2004-12-01

    The NOAA mission is to understand and predict changes in the Earth's environment and conserve and manage coastal and marine resources to meet the Nation's economic, social and environmental needs. NOAA has responsibility for long-term archiving of the United States environmental data and has recently integrated several data management functions into a concept called Scientific Data Stewardship. Scientific Data Stewardship a new paradigm in data management consisting of an integrated suite of functions to preserve and exploit the full scientific value of NOAA's, and the world's, environmental data These functions include careful monitoring of observing system performance for long-term applications, the generation of authoritative long-term climate records from multiple observing platforms, and the proper archival of and timely access to data and metadata. NOAA has developed a conceptual framework to implement the functions of scientific data stewardship. This framework has five objectives: 1) develop real-time monitoring of all satellite observing systems for climate applications, 2) process large volumes of satellite data extending up to decades in length to account for systematic errors and to eliminate artifacts in the raw data (referred to as fundamental climate data records, FCDRs), 3) generate retrieved geophysical parameters from the FCDRs (referred to as thematic climate data records TCDRs) including combining observations from all sources, 4) conduct monitoring and research by analyzing data sets to uncover climate trends and to provide evaluation and feedback for steps 2) and 3), and 5) provide archives of metadata, FCDRs, and TCDRs, and facilitate distribution of these data to the user community. The term `climate data record' and related terms, such as climate data set, have been used for some time, but the climate community has yet to settle on a concensus definition.

  20. Scientific papers: A new paradigm

    Science.gov (United States)

    Reid, George C.

    The problem of how to organize and write a scientific paper is a very basic one for most of us. A scientific paper is, after all, the only tangible product of a research scientist and, like all products, will be a failure if not marketed properly to reach its potential buyers. I think that a lack of attention to this “marketing and sales” aspect of research is a serious fault in our community, by which I mean those of us who publish in AGU journals.The potential audience for a scientific paper can be divided roughly into three distinct categories. The first group is usually rather small in number, consisting of fellow scientists working in a very closely related field, and to whom the details of the work are of major importance. The second group is also fellow scientists, but their interest is less sharply focused, and they are concerned with the broad outlines of the work and essential results. The third group is the sponsors and the people who actually pay for the work, whose interest in the details is minimal and they, sadly enough, are often concerned only with the fact that a paper has been published rather than its content.

  1. Neophilia Ranking of Scientific Journals.

    Science.gov (United States)

    Packalen, Mikko; Bhattacharya, Jay

    2017-01-01

    The ranking of scientific journals is important because of the signal it sends to scientists about what is considered most vital for scientific progress. Existing ranking systems focus on measuring the influence of a scientific paper (citations)-these rankings do not reward journals for publishing innovative work that builds on new ideas. We propose an alternative ranking based on the proclivity of journals to publish papers that build on new ideas, and we implement this ranking via a text-based analysis of all published biomedical papers dating back to 1946. In addition, we compare our neophilia ranking to citation-based (impact factor) rankings; this comparison shows that the two ranking approaches are distinct. Prior theoretical work suggests an active role for our neophilia index in science policy. Absent an explicit incentive to pursue novel science, scientists underinvest in innovative work because of a coordination problem: for work on a new idea to flourish, many scientists must decide to adopt it in their work. Rankings that are based purely on influence thus do not provide sufficient incentives for publishing innovative work. By contrast, adoption of the neophilia index as part of journal-ranking procedures by funding agencies and university administrators would provide an explicit incentive for journals to publish innovative work and thus help solve the coordination problem by increasing scientists' incentives to pursue innovative work.

  2. Lexical Features of Scientific Discourse

    Directory of Open Access Journals (Sweden)

    Tatjana Rusko

    2014-06-01

    Full Text Available Currently, a lot of emphasis is placed of the ability of a person to successfully communicate in any sphere of activity, which along with upbringing and education is among the factors that determine a person’s culture. In the context of rapid scientific and technological progress, it is vital to constantly exchange relevant infor- mation. The effectiveness of this process relies not only on the proficient knowledge of the subject and the ability to make grammatically correct sentences, but to a large extent on the level of competence in scientific language. The present article attempts to consider the interaction of discourse and vocabulary, different types of cognitive phenomena responsible for the use of a language in real time and related to the language as a means of storing and organising information. Analysing and classifying some key elements of a scientific discourse lexicon contributes to the development of certain provisions of lexicology, functional stylistics, cognitive linguistics and terminology. The results of the analysis may be advantageous both to linguistics and teaching the language for specific purposes.

  3. Ethics of reviewing scientific publications.

    2017-05-01

    The approval or rejection of scientific publications can have important consequences for scientific knowledge, so considerable responsibility lies on those who have to assess or review them. Today it seems that the peer review process, far from being considered an outdated system to be abandoned, is experiencing a new upturn. This article proposes criteria for the conduct of reviewers and of those who select them. While commenting on new emerging models, it provides practical recommendations for improving the peer-review system, like strengthening the role of guidelines and training and supporting reviewers. The process of peer review is changing, it is getting more open and collaborative, but those same ethical principles which guided it from its very origin should remain untouched and be firmly consolidated. The paper highlights how the ethics of reviewing scientific publications is needed now more than ever, in particular with regard to competence, conflict of interest, willingness to discuss decisions, complete transparency and integrity.

    The structure and style of representation of the paragraphs about scientific results are adjusted to the research and development program 1979. Since in this program an arrangement according to fields or departments resp. was chosen, the individual reports of this report on results were arranged as to departments too. In doing so, however, a survey of the aims and the development of the department as a whole precedes, and subsequently information on the results of the individual projects is given. In addition to the results of the year under report, the aims during the life of the project are summarized. Para. 2.1 puts the individual FE (research and development) projects into relation to the five research programs, which are at present dealt with by the GBF (Society for Biotechnological Research). The reports on the individual projects refer to the FE program number. For the first time, the report on the results contains a paragraph about the collecting activity and the research work of the DSM (German collection of microorganisms), which became part of the GBF at the beginning of the year under report. A separate paragraph deals with the scientific and technical infrastructure, especially with the work of the Service-Unit 'Biotechnikum' which produces natural substances, which are commercially not available. Paragraphs about further activities in the fields of scientific cooperation, results transfer etc, as well as about the staff and the economical developments of the GBF follow. (orig./AJ) [de

    Conventional computers excel in logic and accurate scientific calculations but make hard work of open ended problems that human brains handle easily. Even von Neumann—the mathematician and polymath who first developed the programming architecture that forms the basis of today's computers—was already looking to the brain for future developments before his death in 1957 [1]. Neuromorphic computing uses approaches that better mimic the working of the human brain. Recent developments in nanotechnology are now providing structures with very accommodating properties for neuromorphic approaches. This special issue, with guest editors James K Gimzewski and Dominique Vuillaume, is devoted to research at the serendipitous interface between the two disciplines. 'Synaptic electronics', looks at artificial devices with connections that demonstrate behaviour similar to synapses in the nervous system allowing a new and more powerful approach to computing. Synapses and connecting neurons respond differently to incident signals depending on the history of signals previously experienced, ultimately leading to short term and long term memory behaviour. The basic characteristics of a synapse can be replicated with around ten simple transistors. However with the human brain having around 1011 neurons and 1015 synapses, artificial neurons and synapses from basic transistors are unlikely to accommodate the scalability required. The discovery of nanoscale elements that function as 'memristors' has provided a key tool for the implementation of synaptic connections [2]. Leon Chua first developed the concept of the 'The memristor—the missing circuit element' in 1971 [3]. In this special issue he presents a tutorial describing how memristor research has fed into our understanding of synaptic behaviour and how they can be applied in information processing [4]. He also describes, 'The new principle of local activity, which uncovers a minuscule life-enabling "Goldilocks zone", dubbed the

    Share is a social networking site with novel, specially designed feature sets to enable simultaneous remote collaboration and sharing of large data sets among scientists. The site will include not only the standard features found on popular consumer-oriented social networking sites such as Facebook and Myspace, but also a number of powerful tools to extend its functionality to a science collaboration site. A Virtual Observatory is a promising technology for making data accessible from various missions and instruments through a Web browser. Sci-Share augments services provided by Virtual Observatories by enabling distributed collaboration and sharing of downloaded and/or processed data among scientists. This will, in turn, increase science returns from NASA missions. Sci-Share also enables better utilization of NASA s high-performance computing resources by providing an easy and central mechanism to access and share large files on users space or those saved on mass storage. The most common means of remote scientific collaboration today remains the trio of e-mail for electronic communication, FTP for file sharing, and personalized Web sites for dissemination of papers and research results. Each of these tools has well-known limitations. Sci-Share transforms the social networking paradigm into a scientific collaboration environment by offering powerful tools for cooperative discourse and digital content sharing. Sci-Share differentiates itself by serving as an online repository for users digital content with the following unique features: a) Sharing of any file type, any size, from anywhere; b) Creation of projects and groups for controlled sharing; c) Module for sharing files on HPC (High Performance Computing) sites; d) Universal accessibility of staged files as embedded links on other sites (e.g. Facebook) and tools (e.g. e-mail); e) Drag-and-drop transfer of large files, replacing awkward e-mail attachments (and file size limitations); f) Enterprise-level data and

    The photo shows a close-up of a Lichtenberg figure – popularly called an “electron tree” – produced in a cylinder of polymethyl methacrylate (PMMA). Electron trees are created by irradiating a suitable insulating material, in this case PMMA, with an intense high energy electron beam. Upon discharge......, during dielectric breakdown in the material, the electrons generate branching chains of fractures on leaving the PMMA, producing the tree pattern seen. To be able to create electron trees with a clinical linear accelerator, one needs to access the primary electron beam used for photon treatments. We...... appropriated a linac that was being decommissioned in our department and dismantled the head to circumvent the target and ion chambers. This is one of 24 electron trees produced before we had to stop the fun and allow the rest of the accelerator to be disassembled....

    Electrons have played a significant role in the development of many fields of physics during the last century. The interest surrounding them mostly involved their wave-like features prescribed by the quantum theory. In particular, these features correctly predict the behaviour of electrons in various physical systems including atoms, molecules, solid-state materials, and even in free space. Ten years ago, new breakthroughs were made, arising from the new ability to bestow orbital angular momentum (OAM) to the wave function of electrons. This quantity, in conjunction with the electron's charge, results in an additional magnetic property. Owing to these features, OAM-carrying, or twisted, electrons can effectively interact with magnetic fields in unprecedented ways and have motivated materials scientists to find new methods for generating twisted electrons and measuring their OAM content. Here, we provide an overview of such techniques along with an introduction to the exciting dynamics of twisted electrons.

    Scientific Investigation with the SJCSI (Saint Jean* Crime Scene Investigation) Our work, which we have been teaching for 3 years, consists of a scientific investigation. We create a case from A to Z and then our students (15 to 16 years old) are meant to collect samples and clues from a reconstituted crime scene and then have to catch the culprit thanks to laboratory tests crossing four subjects: Physics and Chemistry, Biology, Math and English. I'm a biology teacher and I work with 3 other teachers in my school. The objectives of these activities are: • Make sciences more attractive by putting them into a context of crime investigation. • Use science techniques to find a culprit or to clear a suspect. • To acquire scientific knowledge. • Realize that the different scientific subjects complement each other to carry out a survey. • Use English language and improve it. The investigation consists of doing experiments after collecting different samples and clues on the crime scene. Examples of Biology experimentation: • Detecting the origin of the blood samples found on the crime scene. Students observe blood samples with a microscope and compare the characteristics to those of human blood found on the web. They discover that blood samples found aren't human blood because the red cells have a nucleus. By using the information given in the scenario, they discover that blood sample belongs to the parrot of a suspect. Students, also take a photo of their microscopic preparations, add title and caption and so they learn the cell's structure and the characteristics of blood cells. • In another case, students have to study the blood sample found under the victims fingernails. They observe blood preparation and compare it to the blood of a suspect who has a genetic disease: drepanocytosis. So, they discover the characteristics of blood cells by comparing them to sickle cells. • DNA electrophoresis to identify DNA found, for example, on the gun. • Blood type

    During the Great War, the French surgeon Alexis Carrel, in collaboration with the English chemist Henry Dakin, devised an antiseptic treatment for infected wounds. This paper focuses on Carrel's attempt to standardise knowledge of infected wounds and their treatment, and looks closely at the vision of surgical skill he espoused and its difference from those associated with the doctrines of scientific management. Examining contemporary claims that the Carrel-Dakin method increased rather than diminished demands on surgical work, this paper further shows how debates about antiseptic wound treatment opened up a critical space for considering the nature of skill as a vital dynamic in surgical innovation and practice.

    In order to minimize adverse health effects and increase the benefits of physical activity, it is important to systematize indoor air quality study in environments used for physical exercise and sports. To investigate and analyze the scientific production related to indoor air quality of environments used for physical exercise and sports practice through a bibliometric analysis. The databases Scielo, Science Direct, Scopus, Lilacs, Medline via Pubmed, and SportDiscus were searched from their inception to March 2016. Bibliometric analysis was performed for authors, institutions, countries, and collaborative networks, in relation to publication year, theme, citation network, funding agency, and analysis of titles and keywords of publications. Country, area, and impact factor of the journals were analyzed. Of 1281 studies screened, 34 satisfied the inclusion criteria. The first publication occurred in 1975. An increase in publications was observed in the last 15 years. Most of the studies were performed by researchers in the USA, followed by Portugal and Italy. Seventeen different scientific journals have published studies on the subject, and most are in the area of Environmental Sciences. It was noted that the categories of author keywords associated with "Pollutants," "Sport Environment," and "Physical Exercise" were the most commonly used in most studies. A total of 68% of the studies had at least one funding agency, and 81% of studies published in the last decade had funding. Our results demonstrate that there is recent exponential growth, driven in the last decade by researchers in environmental science from European institutions. Copyright © 2017 Elsevier Ltd.

  5. Quantifying the Ease of Scientific Discovery.

    2011-02-01

    It has long been known that scientific output proceeds on an exponential increase, or more properly, a logistic growth curve. The interplay between effort and discovery is clear, and the nature of the functional form has been thought to be due to many changes in the scientific process over time. Here I show a quantitative method for examining the ease of scientific progress, another necessary component in understanding scientific discovery. Using examples from three different scientific disciplines - mammalian species, chemical elements, and minor planets - I find the ease of discovery to conform to an exponential decay. In addition, I show how the pace of scientific discovery can be best understood as the outcome of both scientific output and ease of discovery. A quantitative study of the ease of scientific discovery in the aggregate, such as done here, has the potential to provide a great deal of insight into both the nature of future discoveries and the technical processes behind discoveries in science.

    Full Text Available Electronic commerce can be defined in different ways. Any definition helps to understand and explain that concept as better as possible.. Electronic commerce is a set of procedures and technologies that automate the tasks of financial transactions using electronic means. Also, according to some authors, electronic commerce is defined as a new concept, which is being developed and which includes process of buying and selling or exchanging products, services or information via computer networks, including the Internet. Electronic commerce is not limited just to buying and selling, but it also includes all pre-sales and after-sales ongoing activities along the supply chain. Introducing electronic commerce, using the Internet and Web services in business, realizes the way to a completely new type of economy - internet economy.

    What needs to be done on the long road to evidence-based music therapy? First of all, an adequate research strategy is required. For this purpose the general methodology for therapy research should be adopted. Additionally, music therapy needs a variety of methods of allied fields to contribute scientific findings, including mathematics, natural sciences, behavioral and social sciences, as well as the arts. Pluralism seems necessary as well as inevitable. At least two major research problems can be identified, however, that make the path stony: the problem of specificity and the problem of eclecticism. Neuroscientific research in music is giving rise to new ideas, perspectives, and methods; they seem to be promising prospects for a possible contribution to a theoretical and empirical scientific foundation for music therapy. Despite the huge heterogeneity of theoretical approaches in music therapy, an integrative model of working ingredients in music therapy is useful as a starting point for empirical studies in order to question what specifically works in music therapy. For this purpose, a heuristic model, consisting of five music therapy working factors (attention modulation, emotion modulation, cognition modulation, behavior modulation, and communication modulation) has been developed by the Center for Music Therapy Research (Viktor Dulger Institute) in Heidelberg. Evidence shows the effectiveness of music therapy for treating certain diseases, but the question of what it is in music therapy that works remains largely unanswered. The authors conclude with some questions to neuroscientists, which we hope may help elucidate relevant aspects of a possible link between the two disciplines.

  11. Choosing ESRO's first scientific satellites

    Russo, Arturo

    1992-11-01

    The choice of the scientific payloads of the European Space Research Organization's (ESRO's) first generation of satellites is analyzed. Concentration is on those aspects of the decision process that involved more directly the scientific community and that emerged as major issues in the discussion of the Launching Program Advisory Committee (LPAC). The main theme was the growing competition between the various fields of space science within the progressive retrenching of the Organization's financial resources available for the satellite program. A general overview of the status of the program by the end of 1966 is presented. The choice of the first small satellites' payloads (ESRO 1 and 2, and HEOS-A) and the difficult definition of the TD satellite program are discussed. This part covers a time span going from early 1963 to the spring of 1966. In the second part, the narrative starts from the spring of 1967, when the decision to recommend a second HEOS-type satellite was taken, and then analyzes the complex situation determined by the crisis of the TD program in 1968, and the debates which eventually led to the abandonment of TD-2 and the start of the far less ambitious ESRO 5 project.

    2009-07-01

    A brief history of the Leadership Computing Facility (LCF) initiative is presented, along with the importance of SciDAC to the initiative. The initiative led to the initiation of the Innovative and Novel Computational Impact on Theory and Experiment program (INCITE), open to all researchers in the US and abroad, and based solely on scientific merit through peer review, awarding sizeable allocations (typically millions of processor-hours per project). The development of the nation's LCFs has enabled available INCITE processor-hours to double roughly every eight months since its inception in 2004. The 'top ten' LCF accomplishments in 2009 illustrate the breadth of the scientific program, while the 75 million processor hours allocated to American business since 2006 highlight INCITE contributions to US competitiveness. The extrapolation of INCITE processor hours into the future brings new possibilities for many 'classic' scaling problems. Complex systems and atomic displacements to cracks are but two examples. However, even with increasing computational speeds, the development of theory, numerical representations, algorithms, and efficient implementation are required for substantial success, exhibiting the crucial role that SciDAC will play.

    1990-01-01

    The US Department of Energy (DOE) is moving forward with studies to determine whether Yucca Mountain, Nevada, would be a suitable site for the nation's first high-level radioactive waste repository; however, the DOE's Congressionally mandated task of characterizing the site has been severely delayed by a lack of cooperation from the state of Nevada. The state has refused to issue the appropriate permits that must be obtained before surface disturbing studies can proceed; therefore, an extensive surface-based drilling and trenching program and construction of underground exploration facilities are on hold until pending litigation between the DOE and Nevada has been resolved. Despite this major impasse, significant scientific progress has been made, and the DOE is aggressively pursuing investigations that can be conducted without the state-issued permits. Additionally, the DOE is developing a high-quality technical and management structure as well as equipment, plans, and quality assurance procedures, so that the scientific investigation program can proceed without delay once the appropriate permits are obtained

  15. Scientific issues in fuel behaviour

    International Nuclear Information System (INIS)

    1995-01-01

    The current limits on discharge burnup in today's nuclear power stations have proven the fuel to be very reliable in its performance, with a negligibly small rate of failure. However, for reasons of economy, there are moves to increase the fuel enrichment in order to extend both the cycle time and the discharge burnup. But, longer periods of irradiation cause increased microstructural changes in the fuel and cladding, implying a larger degradation of physical and mechanical properties. This degradation may well limit the plant life, hence the NSC concluded that it is of importance to develop a predictive capability of fuel behaviour at extended burnup. This can only be achieved through an improved understanding of the basic underlying phenomena of fuel behaviour. The Task Force on Scientific Issues Related to Fuel Behaviour of the NEA Nuclear Science Committee has identified the most important scientific issues on the subject and has assigned priorities. Modelling aspects are listed in Appendix A and discussed in Part II. In addition, quality assurance process for performing and evaluating new integral experiments is considered of special importance. Main activities on fuel behaviour modelling, as carried out in OECD Member countries and international organisations, are listed in Part III. The aim is to identify common interests, to establish current coverage of selected issues, and to avoid any duplication of efforts between international agencies. (author). refs., figs., tabs

    1 - Description of program or function: The SCWEB (Scientific Workstation Evaluation Benchmark) software includes 16 programs which are executed in a well-defined scenario to measure the following performance capabilities of a scientific workstation: implementation of FORTRAN77, processor speed, memory management, disk I/O, monitor (or display) output, scheduling of processing (multiprocessing), and scheduling of print tasks (spooling). 2 - Method of solution: The benchmark programs are: DK1, DK2, and DK3, which do Fourier series fitting based on spline techniques; JC1, which checks the FORTRAN function routines which produce numerical results; JD1 and JD2, which solve dense systems of linear equations in double- and single-precision, respectively; JD3 and JD4, which perform matrix multiplication in single- and double-precision, respectively; RB1, RB2, and RB3, which perform substantial amounts of I/O processing on files other than the input and output files; RR1, which does intense single-precision floating-point multiplication in a tight loop, RR2, which initializes a 512x512 integer matrix in a manner which skips around in the address space rather than initializing each consecutive memory cell in turn; RR3, which writes alternating text buffers to the output file; RR4, which evaluates the timer routines and demonstrates that they conform to the specification; and RR5, which determines whether the workstation is capable of executing a 4-megabyte program

  18. [On freedom of scientific research].

    2013-07-01

    Debates about science and, more specifically, about scientific research quickly bring up the question about its freedom. Science is readily blamed for technological disasters or criticized for nursing fantasies of omnipotence and commercial gain. This prompts the call for a restriction of its freedom. At the same time, society's demands on science are enormous, to the effect that science and technology have acquired the status of a deus-ex-machina: they are expected to furnish short-term, affordable, and convenient solutions to a wide range of problems, including issues of health, transportation, food and, more generally, a comfortable life. What kind of freedom is required to meet these expectations? Who is in a position to grant it? What does freedom for science mean and how is it linked to responsibility? The paper examines the current situation of freedom in scientific research and of its restrictions, many of which are mentally or economically conditioned. It calls for the involvement of an informed, self-confident bourgeoisie in research decisions and for the educational measures this necessitates. Finally, it demands a greater appreciation of education (rather than training) as the basis of social trust, and the recognition of continuous education as a productive investment of time and a crucial element in the employment of social goods.

    2016-01-01

    We present a scaling-up plan for AstroComNYC's Methods of Scientific Research (MSR), a course designed to improve undergraduate students' understanding of science practices. The course format and goals, notably the open-ended, hands-on, investigative nature of the curriculum are reviewed. We discuss how the course's interactive pedagogical techniques empower students to learn creativity within the context of experimental design and control of variables thinking. To date the course has been offered to a limited numbers of students in specific programs. The goals of broadly implementing MSR is to reach more students and early in their education—with the specific purpose of supporting and improving retention of students pursuing STEM careers. However, we also discuss challenges in preserving the effectiveness of the teaching and learning experience at scale.

    Microfluidics, a field that has been well-established for several decades, has seen extensive applications in the areas of biology, chemistry, and medicine. However, it might be very hard to imagine how such soft microfluidic devices would be used in other areas, such as electronics, in which stiff, solid metals, insulators, and semiconductors have previously dominated. Very recently, things have radically changed. Taking advantage of native properties of microfluidics, advances in microfluidics-based electronics have shown great potential in numerous new appealing applications, e.g. bio-inspired devices, body-worn healthcare and medical sensing systems, and ergonomic units, in which conventional rigid, bulky electronics are facing insurmountable obstacles to fulfil the demand on comfortable user experience. Not only would the birth of microfluidic electronics contribute to both the microfluidics and electronics fields, but it may also shape the future of our daily life. Nevertheless, microfluidic electronics are still at a very early stage, and significant efforts in research and development are needed to advance this emerging field. The intention of this article is to review recent research outcomes in the field of microfluidic electronics, and address current technical challenges and issues. The outlook of future development in microfluidic electronic devices and systems, as well as new fabrication techniques, is also discussed. Moreover, the authors would like to inspire both the microfluidics and electronics communities to further exploit this newly-established field.

    This article retrieved the publications from the Revista de Saúde Pública journal (from 1967 to 2015) on violence and health, on the SciELO and PubMed bases, by searching for the terms "violence", "suicide", "aggression", "bullying", and "external causes", registered in any part of the text. We found 130 articles (the first one published in 1974). We observed: increase of publications over time, with decrease in the last five years; similar production volume in lethal and non-lethal violence; later publication of the latter; few studies in qualitative research; mostly descriptive production; and visualization of the problem more by the acts than by contexts or motivations and aggressors. Social markers were little approached, appearing, from largest to smallest frequency, social class, gender, race/ethnicity, and generation. Human rights were little used and only recently used as analytical framework, connected more to gender than to social class. Although Revista de Saúde Pública has registered the theme in its publications, consolidating it as scientific production line, there is still great explanatory theoretical rarefaction and little intersectionality between violence, social inequalities, and human rights. RESUMO A produção da Revista de Saúde Pública (de 1967 até 2015) sobre violência e saúde foi recuperada nas bases SciELO e PubMed utilizando-se os termos "violência", "suicídio", "agressões", "bullying" e "causas externas", registrados em qualquer parte do texto. Foram encontrados 130 artigos (o primeiro deles publicado em 1974). Constatou-se: aumento das publicações no tempo, com decréscimo nos últimos cinco anos; volume similar de produção em violência letal e não letal; publicação mais tardia desta última; poucos estudos em pesquisa qualitativa; produção majoritariamente descritiva; e visibilização do problema, mais pelos atos que pelos contextos ou motivações e agressores.

  10. Secure Peer-to-Peer Networks for Scientific Information Sharing

    2012-01-01

    The most common means of remote scientific collaboration today includes the trio of e-mail for electronic communication, FTP for file sharing, and personalized Web sites for dissemination of papers and research results. With the growth of broadband Internet, there has been a desire to share large files (movies, files, scientific data files) over the Internet. Email has limits on the size of files that can be attached and transmitted. FTP is often used to share large files, but this requires the user to set up an FTP site for which it is hard to set group privileges, it is not straightforward for everyone, and the content is not searchable. Peer-to-peer technology (P2P), which has been overwhelmingly successful in popular content distribution, is the basis for development of a scientific collaboratory called Scientific Peer Network (SciPerNet). This technology combines social networking with P2P file sharing. SciPerNet will be a standalone application, written in Java and Swing, thus insuring portability to a number of different platforms. Some of the features include user authentication, search capability, seamless integration with a data center, the ability to create groups and social networks, and on-line chat. In contrast to P2P networks such as Gnutella, Bit Torrent, and others, SciPerNet incorporates three design elements that are critical to application of P2P for scientific purposes: User authentication, Data integrity validation, Reliable searching SciPerNet also provides a complementary solution to virtual observatories by enabling distributed collaboration and sharing of downloaded and/or processed data among scientists. This will, in turn, increase scientific returns from NASA missions. As such, SciPerNet can serve a two-fold purpose for NASA: a cost-savings software as well as a productivity tool for scientists working with data from NASA missions.

  11. The electron

    Hestenes, David; Weingartshofer, Antonio

    1991-01-01

    The stupendous successes of the Dirac equation and quantum electro-dynamics have established the electron as the best understood of the fundamental constituents of matter. Nevertheless, physicists agree that the electron still has secrets to reveal. Moreover, powerful new theoretical and experimental tools for probing those secrets have been sharpened during the last decade. This workshop was organized to bring theorists and experimentalists together to discuss their common goal of knowing the electron. Present state and future prospects for progress toward that goal are here described. The theoretical papers encompass a wide range of views on the electron. Several argue that the 'Zitter-bewegung' is more than a mathematical peculiarity of the Dirac equation, that it may well be a real physical phenomenon and worthy of serious study, theoretically and experimentally. Besides generating the electron spin and magnetic moment, the 'Zitterbewegung' may be a vital clue to electron structure and self-interaction. Some of the papers employ a radical new formulation of the Dirac theory which reveals a hidden geo-metric structure in the theory that supports a 'Zitterbewegung' inter-pretation. For the last half century the properties of electrons have been probed primarily by scattering experiments at ever higher energies. Recently, however, two powerful new experimental techniques have emerged capable of giving alternative experimental views of the electron. First, techniques for confining single electrons for long term study have led to the most accurate measurements of the electron magnetic moment. Second, the interaction of high intensity laser fields with atoms and electrons have revealed striking new phenomena such as multiphoton ionization. refs.; figs.; tabs

    The scanning electron microscope equipped with an x-ray spectrometer is a versatile instrument which has many uses in the investigation of crime and preparation of scientific evidence for the courts. Major applications include microscopy and analysis of very small fragments of paint, glass and other materials which may link an individual with a scene of crime, identification of firearms residues and examination of questioned documents. Although simultaneous observation and chemical analysis of the sample is the most important feature of the instrument, other modes of operation such as cathodoluminescence spectrometry, backscattered electron imaging and direct x-ray excitation are also exploited. Marks on two bullets or cartridge cases can be compared directly by sequential scanning with a single beam or electronic linkage of two instruments. Particles of primer residue deposited on the skin and clothing when a gun is fired can be collected on adhesive tape and identified by their morphology and elemental composition. It is also possible to differentiate between the primer residues of different types of ammunition. Bullets may be identified from the small fragments left behind as they pass through the body tissues. In the examination of questioned documents the scanning electron microscope is used to establish the order in which two intersecting ink lines were written and to detect traces of chemical markers added to the security inks on official documents.

    I'm going to talk about the worldwide market for scientific lasers. I felt we should start with a quote from our soon-to-be President and learn from him how he feels about the commitment that the government should make to R&D. "R&D is the economic Fountain of Youth, and we really should take good care of it because that is where our business is for the future." If you read through that quote, it is very clear that at least before the election, he made a very strong commitment to this. It will be interesting to see over the next four years whether he keeps to that commitment or not, but I happen to totally agree with what he is saying here. The R&D market, as I see it, is certainly, as far as lasers are concerned, the growth place for new technology and applications.

    Petroleum is one of Malaysia's major commodities. In 1993 alone, Malaysia exported about 21 million tonne crude petroleum and 3.4 million tonne of petroleum products with export value of about RM 9.2 billion. Despite the large local and export market of the fuel, our petroleum industry is facing several difficulties. The supply of petrol will inevitably deplete. The industry faces an increase in the exploration costs and decline in the discovery of large reserves. Petronas research and scientific services Sdn Bhd was established 3 years ago. The company which supports its holding company's needs in R and D started its history as an analytical laboratory in 1978. Today, it is one of the leading upstream and downstream petroleum research institute in this region

    Full text: Previous studies realized by our group have demonstrated radio-induction of genotoxic damage in peripheral blood of hospital workers exposed to chronic X-ray. The cytogenetic and cytomolecular damage was significant in the radiologists evaluated. Accordingly, we have researched the knowledge of risk radiation in 57 workers to different health centres, private and public, in La Plata city. Most of respondents (96.4%) answered to know the risk of working with radiation ionizing, but a large portion do not carry out with the appropriate safety rules. The workers have not interest in this rules, it is evidenced by negligence in the use of protective clothing and personal dosimeters. These results suggested that individuals could be sensitising to minimize their risk. For this purpose we are working in scientific literacy conferences which are organized by 'Asociacion de Tecnicos Radiologos y de Diagnostico por Imagenes de La Plata (ASTEDIRLP)'. (author)

    This article discusses the questions associated with the use of reference systems in the preparation of graduates in physical function. The objective of this research is creation of model of recommender system user from the sphere of science and education. The detailed review of current scientific and social network for scientists and the problem of constructing recommender systems in this area. The result of this study is to research user information model systems. The model is presented in two versions: the full one - in the form of a semantic network, and short - in a relational form. The relational model is the projection in the form of semantic network, taking into account the restrictions on the amount of bonds that characterize the number of information items (research results), which interact with the system user.

    It's been 16 years since I first took a physics class at Weber State University. Since them, I've survived graduate school in Nuclear Engineering, and a postdoc appointment doing nuclear nonproliferation. Now I'm a Technical Staff Member at Los Alamos National Laboratory working with nuclear data, the physics behind the numerical simulations of nuclear reactors and nuclear weapons. Along the way, I've learned a few things. First, scientific computing is everywhere in science. If you are not writing codes, you will be analyzing their output, and generally there will be more output than a human can correctly and accurately interpret in a timely manner. Second, a career in science or engineering can be very rewarding with opportunities to collaborate with and generate friendships with very bright people from all over the world.

  20. Helping to expand scientific knowledge

    International Nuclear Information System (INIS)

    1969-01-01

    Nuclear research has spread rapidly across practically all of the established sciences. It has been a dynamic and creative process in which the Agency has been able to play a constructive role. One of the methods has been the programme of research contracts. This has provided financial support for research involving some form of nuclear technology to physicists, chemists, medical doctors, hydrologists, entomologists, geneticists and scientists in many other disciplines. It is a system almost unique within the United Nations family, though the World Health Organization (WHO) also supports medical research under contract. An examination of the programme and its catalysing and co-ordinating effects in the expansion of scientific knowledge is made here by Clarence O'Neal, of the Division of Research and Laboratories.

  1. Superphenix: technical and scientific achievements

    International Nuclear Information System (INIS)

    Guidez, Joel; Prele, Gerard

    2016-04-01

    In this book, the authors propose a synthesis of technical and scientific achievements related to the design, fabrication and eleven-year operation of Superphenix, the most powerful fast breeder reactor ever built and operated. They had the opportunity to use various and important archives maintained by the different involved institutions, actors and companies, such as the CEA with its MADONA database, AREVA and EDF. They address all the different fields: construction, chemistry, exploitation, handling, small and large components, materials, fuel manufacturing, environmental assessment, thermal hydraulics, the sodium-water reaction, sodium fires, the release of residual power, in-service inspection, and dismantling operations. Moreover, a chapter addresses design studies for Superphenix 2 and for the European Fast Reactor (EFR) which should be the successors of Superphenix

    Novelty is an essential feature of creative ideas, yet the building blocks of new ideas are often embodied in existing knowledge. From this perspective, balancing atypical knowledge with conventional knowledge may be critical to the link between innovativeness and impact. Our analysis of 17.9 million papers spanning all scientific fields suggests that science follows a nearly universal pattern: The highest-impact science is primarily grounded in exceptionally conventional combinations of prior work yet simultaneously features an intrusion of unusual combinations. Papers of this type were twice as likely to be highly cited works. Novel combinations of prior work are rare, yet teams are 37.7% more likely than solo authors to insert novel combinations into familiar knowledge domains.

    2017-10-15

    This Final Scientific Report addresses the accomplishments achieved during Phase I of DE- FE0023985, Coal Syngas Combustor Development for Supercritical CO2 Power Cycles. The primary objective of the project was to develop a coal syngas-fueled combustor design for use with high-pressure, high-temperature, oxy-fuel, supercritical CO2 power cycles, with particular focus given to the conditions required by the Allam Cycle. The primary goals, from the Statement of Project Objectives, were to develop: (1) a conceptual design of a syngas-fueled combustor-turbine block for a 300MWe high-pressure, oxy-fuel, sCO2 power plant; (2) the preliminary design of a 5MWt test combustor; and (3) the definition of a combustor test program. Accomplishments for each of these goals are discussed in this report.

  5. The martial art of scientific publication

    Science.gov (United States)

    Parker, E. N.

    Publication of scientific results in refereed journals is an essential part of the scientific process. It is the final payoff for the obscure labors that compose scientific research. Unfortunately, effective operation of the publication procedure requires simultaneous rational scientific judgment on the part of the author, the referee, and the editor, and the coincidence of all of these cannot be taken for granted on every given occasion. There are times when the working definition of truth is taken to be the consensus of one's scientific intimates: the “good old boys.” Anything outside that limited horizon is discomforting and improper and is to be barred from consideration.

    Should scientific facts and methods have an epistemically privileged status in public reason? In Rawls’s public reason account he asserts what we will label the Scientific Standard Stricture: citizens engaged in public reason must be guided by non-controversial scientific methods, and public reason...... must be in line with non-controversial scientific conclusions. The Scientific Standard Stricture is meant to fulfill important tasks such as enabling the determinateness and publicity of the public reason framework. However, Rawls leaves us without elucidation with regard to when science...

  7. Can scientific medicine incorporate alternative medicine?

    Science.gov (United States)

    Federspil, G; Vettor, R

    2000-06-01

    The authors examine the problem of defining alternative medicine, and after a brief analysis conclude that a satisfactory unifying definition of the different practices is not possible. Scientific knowledge is a function of scientific method. In turn the principle of falsifiability proposed by Karl Popper is used as a demarcation line between science and pseudoscience. They assert that the various alternative modalities do not represent authentic scientific disciplines, as they lack many of the minimum requirements of scientific discourse and, above all, because they violate the principle of falsifiability. Until they overcome these methodological shortcomings, alternative medical practices cannot become authentic scientific disciplines.

  8. Peer Review in Scientific Publications: Benefits, Critiques, & A Survival Guide

    Science.gov (United States)

    Kelly, Jacalyn; Sadeghieh, Tara

    2014-01-01

    Peer review has been defined as a process of subjecting an author’s scholarly work, research or ideas to the scrutiny of others who are experts in the same field. It functions to encourage authors to meet the accepted high standards of their discipline and to control the dissemination of research data to ensure that unwarranted claims, unacceptable interpretations or personal views are not published without prior expert review. Despite its wide-spread use by most journals, the peer review process has also been widely criticised due to the slowness of the process to publish new findings and due to perceived bias by the editors and/or reviewers. Within the scientific community, peer review has become an essential component of the academic writing process. It helps ensure that papers published in scientific journals answer meaningful research questions and draw accurate conclusions based on professionally executed experimentation. Submission of low quality manuscripts has become increasingly prevalent, and peer review acts as a filter to prevent this work from reaching the scientific community. The major advantage of a peer review process is that peer-reviewed articles provide a trusted form of scientific communication. Since scientific knowledge is cumulative and builds on itself, this trust is particularly important. Despite the positive impacts of peer review, critics argue that the peer review process stifles innovation in experimentation, and acts as a poor screen against plagiarism. Despite its downfalls, there has not yet been a foolproof system developed to take the place of peer review, however, researchers have been looking into electronic means of improving the peer review process. Unfortunately, the recent explosion in online only/electronic journals has led to mass publication of a large number of scientific articles with little or no peer review. This poses significant risk to advances in scientific knowledge and its future potential. The current

    Bangerth, W.; Heister, T.; Hwang, L.; Kellogg, L. H.

    2016-12-01

    Developing sustainable open source software packages for the sciences appears at first to be primarily a technical challenge: How can one create stable and robust algorithms, appropriate software designs, sufficient documentation, quality assurance strategies such as continuous integration and test suites, or backward compatibility approaches that yield high-quality software usable not only by the authors, but also the broader community of scientists? However, our experience from almost two decades of leading the development of the deal.II software library (http://www.dealii.org, a widely-used finite element package) and the ASPECT code (http://aspect.dealii.org, used to simulate convection in the Earth's mantle) has taught us that technical aspects are not the most difficult ones in scientific open source software. Rather, it is the social challenge of building and maintaining a community of users and developers interested in answering questions on user forums, contributing code, and jointly finding solutions to common technical and non-technical challenges. These problems are posed in an environment where project leaders typically have no resources to reward the majority of contributors, where very few people are specifically paid for the work they do on the project, and with frequent turnover of contributors as project members rotate into and out of jobs. In particular, much software work is done by graduate students who may become fluent enough in a software only a year or two before they leave academia. We will discuss strategies we have found do and do not work in maintaining and growing communities around the scientific software projects we lead. Specifically, we will discuss the management style necessary to keep contributors engaged, ways to give credit where credit is due, and structuring documentation to decrease reliance on forums and thereby allow user communities to grow without straining those who answer questions.

  10. Scientific progress report 2 - 1975

    International Nuclear Information System (INIS)

    1975-01-01

    The work in the field of radiation chemistry was carried out in the year 1975 in the following work groups: Pulsed radiolysis (P), reaction kinematics (RK), and insulators and synthetics (IK). Continuing running research work, the groups P and IK together used the electron accelerator (16 MeV linear accelerator and 1.5 MeV Van de Graaff generator) as well as a laser flash irradiation apparatus (Rubin laser). The new electron accelerator for the nanosecond region ELBENA was installed. Test runs were started. Furthermore, two additional pulsable laser devices were acquired (one of these for work in the picosecond region), which are to be put in operation in 1976. The main topic of investigation in the work group P was the solving of complex reaction mechanisms and the determination of physical-chemical properties of short-lived intermediary products in the investigation of biologically relevant and micelle systems. The problems worked on are partly closely related to problems concerning the photochemical use of solar energy. This involves, e.g., the light-induced reduction of metal ions and the photoionization in micelle systems. The work group RK continued work on elastic, inelastic and reactive scattering processes between ions and molecules as well as electron transfer processes between atoms and molecules. The problems investigated are of fundamental importance to the understanding of chemical elementary processes in the gas phase relevant to procedures in space. The work group IK concentrate on studies for the production and transport of charge carriers in hydrocarbons and liquidized noble gases; amongst others, the electron mobility in short chain paraffins and polyethylene was investigated. A further main topic of investigation was the decomposition of polymers which, amongst others, brought considerable knowledge on the motion of macromolecules and a new method of detecting the preferential solvation of macrolecules.

    2018-01-01

    In many scientific disciplines, each new 'product' of research (method, finding, artifact, etc.) is often built upon previous findings-leading to extension and branching of scientific concepts over time. We aim to understand the evolution of scientific concepts by placing them in phylogenetic hierarchies where scientific keyphrases from a large, longitudinal academic corpora are used as a proxy of scientific concepts. These hierarchies exhibit various important properties, including power-law degree distribution, power-law component size distribution, existence of a giant component and less probability of extending an older concept. We present a generative model based on preferential attachment to simulate the graphical and temporal properties of these hierarchies which helps us understand the underlying process behind scientific concept evolution and may be useful in simulating and predicting scientific evolution.

  14. Improving the scientific misconduct hearing process.

    Science.gov (United States)

    Parrish, D M

    The overturning and withdrawal of several of the Office of Research Integrity's (ORI's) findings of scientific misconduct have called its role into question. The contested findings of scientific misconduct that have been tried before the hearing body have been based on lengthy and expensive ORI investigations. How could ORI have failed to prove its findings of scientific misconduct after the commitment of substantial resources that far exceed those devoted during institutional investigations? One reason may be that the current hearing process makes it difficult or impossible for ORI, institutions, or individuals to prove scientific misconduct. The hearing process has been criticized by discouraged whistleblowers who believe that their allegations of scientific misconduct should have been upheld, and by the accused for the expensive and protracted nature of the proceedings. The following article examines problems in the scientific misconduct hearing process and suggests that the process could be improved by letting administrative law judges, patent attorneys, and a scientific majority decide these cases.

    2011-03-01

    Cloud computing has the potential to open up high-performance computational science to a much broader class of researchers, owing to its ability to provide on-demand, virtualized computational resources. However, before such approaches can become commonplace, user-friendly tools must be developed that hide the unfamiliar cloud environment and streamline the management of cloud resources for many scientific applications. We have recently shown that high-performance cloud computing is feasible for parallelized x-ray spectroscopy calculations. We now present benchmark results for a wider selection of scientific applications focusing on electronic structure and spectroscopic simulation software in condensed matter physics. These applications are driven by an improved portable interface that can manage virtual clusters and run various applications in the cloud. We also describe a next generation of cluster tools, aimed at improved performance and a more robust cluster deployment. Supported by NSF grant OCI-1048052.

    The CEBAF accelerator at Jefferson laboratory can deliver CW electron beams to three experimental halls simultaneously. A large fraction of the approved scientific program at the lab requires polarized electron beams. Many of these experiments, both polarized and unpolarized, require high average beam current as well. Since all electrons delivered to the experimental halls originate from the same cathode, delivery of polarized beam to a single hall requires using the polarized source to deliver beam to all experiments in simultaneous operation. The polarized source effort at Jefferson Lab is directed at obtaining very long polarized source operational lifetimes at high average current and beam polarization; at developing the capability to deliver all electrons leaving the polarized source to the experimental halls; and at delivering polarized beam to multiple experimental halls simultaneously. Initial operational experience with the polarized source will be presented. copyright 1998 American Institute of Physics

  11. Ontolology Negotiation Between Scientific Archives

    Science.gov (United States)

    Bailin, Sidney C.; Truszkowski, Walt; Obenschain, Arthur F. (Technical Monitor)

    2001-01-01

    This paper describes an approach to ontology negotiation between information agents. Ontologies are declarative (data driven) expressions of an agent's "world": the objects, operations, facts, and rules that constitute the logical space within which an agent performs. Ontology negotiation enables agents to cooperate in performing a task, even if they are based on different ontologies. 'Me process allows agents to discover ontology conflicts and then, though incremental interpretation, clarification, and explanation, establish a common basis for communicating with each other. The need for ontology negotiation stems from the proliferation of information sources and of agents with widely varying specialty expertise. The unmanageability of massive amounts of web-based information is already becoming apparent. It is starting to have an impact on professions that rely on distributed archived information. If the expansion continues at its present rate without an ontology negotiation process being introduced, there will soon be no way to ensure the accuracy and completeness of information that scientists obtain from sources other than their own experiments. Ontology negotiation is becoming increasingly recognized as a crucial element of scalable agent technology. This is because agents, by their very nature, are supposed to operate with a fair amount of autonomy and independence from their end-users. Part of this independence is the ability to enlist other agents for help in performing a task (such as locating information on the web). The agents enlisted for help may be "owned" by a different end-user or organization (such as a document archive), and there is no guarantee that they will use the same terminology or understand the same concepts (objects, operators, theorems, rules) as the recruiting agent. For NASA, the need for ontology negotiation arises at the boundaries between scientific disciplines. For example: modeling the effects of global warming might involve

  12. From scientific instrument to industrial machine coping with architectural stress in embedded systems

    CERN Document Server

    Doornbos, Richard

    2012-01-01

    Architectural stress is the inability of a system design to respond to new market demands. It is an important yet often concealed issue in high tech systems. In From scientific instrument to industrial machine, we look at the phenomenon of architectural stress in embedded systems in the context of a transmission electron microscope system built by FEI Company. Traditionally, transmission electron microscopes are manually operated scientific instruments, but they also have enormous potential for use in industrial applications. However, this new market has quite different characteristics. There are strong demands for cost-effective analysis, accurate and precise measurements, and ease-of-use. These demands can be translated into new system qualities, e.g. reliability, predictability and high throughput, as well as new functions, e.g. automation of electron microscopic analyses, automated focusing and positioning functions. From scientific instrument to industrial machine takes a pragmatic approach to the proble...

    A description of the control and data transfer management system for scientific instrumentation involved in the GAMMA-400 space project is given. The technical capabilities of all specialized equipment to provide the functioning of the scientific instrumentation and satellite support systems are unified in a single structure. Control of the scientific instruments is maintained using one-time pulse radio commands, as well as program commands in the form of 16-bit code words, which are transmitted via onboard control system and scientific data acquisition system. Up to 100 GByte of data per day can be transferred to the ground segment of the project. The correctness of the proposed and implemented structure, engineering solutions and electronic elemental base selection has been verified by the experimental working-off of the prototype of the GAMMA-400 scientific complex in laboratory conditions.

    Paper is ubiquitous in everyday life and a truly low-cost substrate. The use of paper substrates could be extended even further, if electronic applications would be applied next to or below the printed graphics. However, applying electronics on paper is challenging. The paper surface is not only very rough compared to plastics, but is also porous. While this is detrimental for most electronic devices manufactured directly onto paper substrates, there are also approaches that are compatible with the rough and absorptive paper surface. In this review, recent advances and possibilities of these approaches are evaluated and the limitations of paper electronics are discussed. Copyright © 2011 WILEY-VCH Verlag GmbH & Co.

    The roots, stems, leaves, and vascular circuitry of higher plants are responsible for conveying the chemical signals that regulate growth and functions. From a certain perspective, these features are analogous to the contacts, interconnections, devices, and wires of discrete and integrated electronic circuits. Although many attempts have been made to augment plant function with electroactive materials, plants’ “circuitry” has never been directly merged with electronics. We report analog and digital organic electronic circuits and devices manufactured in living plants. The four key components of a circuit have been achieved using the xylem, leaves, veins, and signals of the plant as the template and integral part of the circuit elements and functions. With integrated and distributed electronics in plants, one can envisage a range of applications including precision recording and regulation of physiology, energy harvesting from photosynthesis, and alternatives to genetic modification for plant optimization.
