  1. World wide spatial capital.

    Science.gov (United States)

    Sen, Rijurekha; Quercia, Daniele

    2018-01-01

    In its most basic form, the spatial capital of a neighborhood entails that most aspects of daily life are located close at hand. Urban planning researchers have widely recognized its importance, not least because it can be transformed in other forms of capital such as economical capital (e.g., house prices, retail sales) and social capital (e.g., neighborhood cohesion). Researchers have already studied spatial capital from official city data. Their work led to important planning decisions, yet it also relied on data that is costly to create and update, and produced metrics that are difficult to compare across cities. By contrast, we propose to measure spatial capital in cheap and standardized ways around the world. Hence the name of our project "World Wide Spatial Capital". Our measures are cheap as they rely on the most basic information about a city that is currently available on the Web (i.e., which amenities are available and where). They are also standardized because they can be applied in any city in the five continents (as opposed to previous metrics that were mainly applied in USA and UK). We show that, upon these metrics, one could produce insights at the core of the urban planning discipline: which areas would benefit the most from urban interventions; how to inform planning depending on whether a city's activity is mono- or poly-centric; how different cities fare against each other; and how spatial capital correlates with other urban characteristics such as mobility patterns and road network structure.

    Wohlers, H.C.

    1975-01-01

    Man and the physical and natural resources necessary to support him in a civilized society are on a collision course. It is simple to say that man cannot continue to grow in number at an ever-increasing rate without a destructive effect upon the environment. Positive scientific proof for this impending calamity is not now available, yet many indications--sometimes physical and sometimes natural--point toward major world-wide environmental troubles in the near future. A number of environmental problems are described, particularly as they relate to the total world system. A computer model simulating future world-wide environmental trends from 1900 to 2100 A.D. is evaluated and suggested as a major tool for data-gathering purposes to determine the extent of world-wide environmental problems. It is suggested that scientists take an active role in the study of the environment, particularly in relation to man's future on earth

    1992-01-01

    Purpose - The World-Wide Web (W-3) initiative is a practical project designed to bring a global information universe into existence using available technology. This paper seeks to describe the aims, data model, and protocols needed to implement the "web" and to compare them with various contemporary systems. Design/methodology/approach - Since Vannevar Bush's article, men have dreamed of extending their intellect by making their collective knowledge available to each individual by using machines. Computers provide us two practical techniques for human-knowledge interface. One is hypertext, in which links between pieces of text (or other media) mimic human association of ideas. The other is text retrieval, which allows associations to be deduced from the content of text. The W-3 ideal world allows both operations and provides access from any browsing platform. Findings - Various server gateways to other information systems have been produced, and the total amount of information available on the web is...

  3. Golden Jubilee Photos: World Wide Web

    CERN Multimedia

    2004-01-01

    At the end of the 1980s, the Internet was already a valuable tool to scientists, allowing them to exchange e-mails and to access powerful computers remotely. A more simple means of sharing information was needed, however, and CERN, with its long tradition of informatics and networking, was the ideal place to find it. Moreover, hundreds of scientists from all over the world were starting to work together on preparations for the experiments at the Large Electron-Positron (LEP) collider. In 1989, Tim Berners-Lee (see photo), a young scientist working at CERN, drafted a proposal for an information-management system combining the internet, personal computers and computer-aided document consultation, known as hypertext. In 1990 he was joined by Robert Cailliau and the weaving of the World Wide Web began in earnest, even though only two CERN computers were allocated to the task at the time. The Web subsequently underwent a steady expansion to include the world's main particle physics institutes. The Web was not the...

    Full Text Available The article is aimed at researching bitcoin, the digital currency. It has been found that Bitcoin is a cryptocurrency, that is, the virtual money, which has no material equivalent. The history of creation and development of cryptocurrency was reviewed. There is a reduction in volatility, which guarantees the security of currency, as well as the increase in currency volume and the inability to estimate the profitability of bitcoins. The dynamics of the value of digital currency in US dollars over recent years has been analyzed. Improvement of attitude of many countries to the considered cryptocurrency, in particular the USA, Germany, Spain, Canada, Australia, Israel and Scandinavian countries has been identified. The reasons of Ukraine’s interest in Bitcoin have been considered. Possibilities of creation of cryptocurrency on the territory of Ukraine have been analyzed, i.e. cost of electricity for mining, the legal status of mining firms, and the attitude of the National Bank of Ukraine to the digital currency. It has been concluded that the recognition of Bitcoin by the world countries in the future will allow it to be granted the status of world-wide currency.

  5. Review of stellarator research world wide

    International Nuclear Information System (INIS)

    Shonet, J.L.

    1987-01-01

    The world-wide effort in stellarators has evolved considerably during the past few years. Stellarator facilities are located in the Australia, Federal Republic of Germany, Japan, the Soviet Union, Spain, the United Kingdom and the United States. Dimensions of stellarators range from less than 20 centimeters in major radius to more than 2 meters, and magnetic field values between 0.2 Tesla to more than 3.0 Tesla. Stellarators are made in a variety of magnetic configurations with wide ranges of toroidal aspect ratios and methods of generating the stellarator magnetic surfaces. In particular, continuous helical coils, twisted modular coils, or twisted vacuum chambers all provide different means to generate nested toroidal magnetic surfaces without the need for currents flowing in the plasma. The goal of present day experiments is to accumulate a physics data base. This is being done by increasing electron and ion temperatures with non-ohmic heating, by transport and scaling studies considering neoclassical scaling, global scaling, effects of electric fields, the bootstrap current and magnetic islands. Higher betas are being attempted by designing suitable magnetic configurations, pellet injection and/or minimizing transport losses. Plasma-wall interactions and particle control are being examined by divertor, pumped-limiter and carbonization experiments

  6. MIMAS, setting the world-wide standard for plutonium recycling

    International Nuclear Information System (INIS)

    Vandergheynst Alain; Yvon Vanderborck

    2005-01-01

    Deployment of MIMAS MOX fuel irradiation started in 1985 with loading and irradiation in French 900 MWe PWR of EDF. A 20-year comprehensive R and D programme preceded it. This success was greatly facilitated by some early strategy advantages: 1) Development and licensing of a 'UO 2 -like' MOX fuel rod fully interchangeable with UO 2 rods; 2) Joint SCK/BN operation of the BR2 (MTR) and BR3 (PWR) reactors, pilot and industrial MOX fuel plants, PIE hot laboratories in the Mol/Dessel site. The period since 1985 saw the occurrence of some concurrent facts, that have incontestably led MIMAS to the world-wide leader position (99 % of actual MOX fuel is MIMAS): 1) BN-MIMAS has been selected by Cogema for its plants MELOX and Cadarache and has demonstrated to be a flexible, scalable, and industrial process. 2) MIMAS has been further selected by JNFL for its Japanese domestic MOX plant (Rokkasho-mura) and by US-DOE for its domestic MOX plant (Savannah-NC) for the disposition of 34-ton weapon-Pu. 3) Satisfactory fabrication and irradiation over 1840 metric tons of MIMAS MOX fuel. In order to face the worldwide on-going electricity market liberalisation, MIMAS makers and vendors must definitely improve the MOX performances to compete with continuously improving UO 2 fuel. The facing of this continuous challenge is also reviewed in the paper. (authors)

    1995-01-01

    NASA Langley Research Center (LaRC) began using the World Wide Web (WWW) in the summer of 1993, becoming the first NASA installation to provide a Center-wide home page. This coincided with a reorganization of LaRC to provide a more concentrated focus on technology transfer to both aerospace and non-aerospace industry. Use of WWW and NCSA Mosaic not only provides automated information dissemination, but also allows for the implementation, evolution and integration of many technology transfer and technology awareness applications. This paper describes several of these innovative applications, including the on-line presentation of the entire Technology OPportunities Showcase (TOPS), an industrial partnering showcase that exists on the Web long after the actual 3-day event ended. The NASA Technical Report Server (NTRS) provides uniform access to many logically similar, yet physically distributed NASA report servers. WWW is also the foundation of the Langley Software Server (LSS), an experimental software distribution system which will distribute LaRC-developed software. In addition to the more formal technology distribution projects, WWW has been successful in connecting people with technologies and people with other people.

    International Nuclear Information System (INIS)

    Kugeler, K.

    1995-01-01

    In the future the world-wide energy demand is going to increase considerably. The use of nuclear energy will continuously grow if the demand of climate researchers for a reduction of the world-wide CO 2 emission is fulfilled and if the possible contribution of regenerative energy sources is assessed realistically. In the future a world-wide use of nuclear energy will be realised according to even higher safety standards. The modification of the German Atom Law, which determines the limitation of damage caused to the reactor plant for future reactors fulfils this demand. The efforts in the field of nuclear technical development will concentrate on the proof of the required safety properties. (orig.) [de

  17. Wired World-Wide Web Interactive Remote Event Display

    Energy Technology Data Exchange (ETDEWEB)

    De Groot, Nicolo

    2003-05-07

    WIRED (World-Wide Web Interactive Remote Event Display) is a framework, written in the Java{trademark} language, for building High Energy Physics event displays. An event display based on the WIRED framework enables users of a HEP collaboration to visualize and analyze events remotely using ordinary WWW browsers, on any type of machine. In addition, event displays using WIRED may provide the general public with access to the research of high energy physics. The recent introduction of the object-oriented Java{trademark} language enables the transfer of machine independent code across the Internet, to be safely executed by a Java enhanced WWW browser. We have employed this technology to create a remote event display in WWW. The combined Java-WWW technology hence assures a world wide availability of such an event display, an always up-to-date program and a platform independent implementation, which is easy to use and to install.

    2005-01-01

    This article describes recent improvements in mapping a highly representative set of the world-wide scientific literature. The process described in this article extends existing work in this area in three major ways. First, we argue that a separate structural analysis of current literature vs. reference literature is required for R&D planning. Second, visualization software is used to improve coverage of the literature while maintaining structural integrity. Third, quantitative techniques for measuring the structural integrity of a map are introduced. Maps with high structural integrity, covering far more of the available literature, are presented.

  7. Remote sensing education and Internet/World Wide Web technology

    2001-01-01

    Remote sensing education is increasingly in demand across academic and professional disciplines. Meanwhile, Internet technology and the World Wide Web (WWW) are being more frequently employed as teaching tools in remote sensing and other disciplines. The current wealth of information on the Internet and World Wide Web must be distilled, nonetheless, to be useful in remote sensing education. An extensive literature base is developing on the WWW as a tool in education and in teaching remote sensing. This literature reveals benefits and limitations of the WWW, and can guide its implementation. Among the most beneficial aspects of the Web are increased access to remote sensing expertise regardless of geographic location, increased access to current material, and access to extensive archives of satellite imagery and aerial photography. As with other teaching innovations, using the WWW/Internet may well mean more work, not less, for teachers, at least at the stage of early adoption. Also, information posted on Web sites is not always accurate. Development stages of this technology range from on-line posting of syllabi and lecture notes to on-line laboratory exercises and animated landscape flyovers and on-line image processing. The advantages of WWW/Internet technology may likely outweigh the costs of implementing it as a teaching tool.

    The WorldWide Telescope Ambassadors (WWTA) Program has a track record of inspiring middle school students and getting them excited about science. The WorldWide Telescope (WWT) is a stunningly beautiful and freely available data visualization environment developed by Microsoft Research in collaboration with professional astronomers. Trained volunteer Ambassadors show teachers and students how to use WWT in their classrooms to explore and learn about our Universe. Our initial study has shown that WWT increases student understanding of astrophysical concepts and interest in astronomy and science. As an example of how excited students feel about learning astronomy with WWT, one middle school boy exclaimed, “This is way cooler than Call of Duty!” Our vision is to capitalize on the demonstrated inspirational and educational potential of WWT to increase the number of students who express interest in STEM fields. In this oral presentation, we provide a status update on the WWTA program, including ongoing results from our work with over 700 middle school students to date, and preliminary results from a new NSF-funded study comparing learning and interest gains for students studying Moon phases with WWT vs with the 2-dimensional simulator activity that accompanies their textbook.

    2011-09-01

    Digital planetariums can provide a broader range of educational experiences than the more classical planetariums that use star-balls. This is because of their ability to project images, content from current research, and the 3-D distribution of the stars and galaxies. While there are hundreds of planetariums in the country, the reason that few of these are fully digital is the cost. In collaboration with Microsoft Research (MSR), we have developed a way to digitize existing planetariums for approximately $40,000 using freely available software. We describe here how off the shelf equipment, together with a WorldWide Telescope client, can provide a rich and truly interactive experience. This will enable students and the public to pan though multi-wavelength full-sky scientific data sets, explore 3-D visualizations of our Solar System (including trajectories of millions of minor planets), near-by stars, and the SDSS galaxy catalog.

    2014-01-01

    The ATLAS collaboration accounts for more than 3000 members located all over the world. The efficiency of the experiment can be improved allowing system experts not present on site to follow the ATLAS operations in real-time, spotting potential problems which otherwise may remain unattended for a non-negligible time. Taking into account the wide geographical spread of the ATLAS collaboration, the solution of this problem is to have all monitoring information with minimal access latency available world-wide. We have implemented a framework which defines a standard approach for retrieving arbitrary monitoring information from the ATLAS private network via HTTP. An information request is made by specifying one of the predefined URLs with some optional parameters refining data which has to be shipped back in XML format. The framework takes care of receiving, parsing and forwarding such requests to the appropriate plugins. The plugins retrieve the requested data and convert it to XML (or optionally to JSON) format...

    Nelson, Michael L.; Gottlich, Gretchen L.; Bianco, David J.

    1994-01-01

    On January 14, 1993, NASA Langley Research Center (LaRC) made approximately 130 formal, 'unclassified, unlimited' technical reports available via the anonymous FTP Langley Technical Report Server (LTRS). LaRC was the first organization to provide a significant number of aerospace technical reports for open electronic dissemination. LTRS has been successful in its first 18 months of operation, with over 11,000 reports distributed and has helped lay the foundation for electronic document distribution for NASA. The availability of World Wide Web (WWW) technology has revolutionized the Internet-based information community. This paper describes the transition of LTRS from a centralized FTP site to a distributed data model using the WWW, and suggests how the general model for LTRS can be applied to other similar systems.

    2013-02-01

    The World Wide Web is increasingly becoming an important source of information for healthcare professionals. However, finding reliable information from unauthoritative Web sites to inform healthcare can pose a challenge to nurses. A study, using grounded theory, was undertaken in two phases to understand how qualified nurses judge the quality of Web nursing information. Data were collected using semistructured interviews and focus groups. An explanatory framework that emerged from the data showed that the judgment process involved the application of forms of knowing and modes of cognition to a range of evaluative tasks and depended on the nurses' critical skills, the time available, and the level of Web information cues. This article mainly focuses on the six evaluative tasks relating to assessing user-friendliness, outlook and authority of Web pages, and relationship to nursing practice; appraising the nature of evidence; and applying cross-checking strategies. The implications of these findings to nurse practitioners and publishers of nursing information are significant.

An electronic periodical is usually defined as a regular publication on some particular topic distributed in digital form, chiefly through the Web, but also by electronic mail or digital disk. The author has surveyed 106 publications. Thirty-four are distributed only on the Web, and 72 have printed versions. The number of analysed publications is not very big, but four years of electronic publishing and the variety of periodicals enables us to establish the causes of this phenomenon, the main features of development, and some perspectives. Electronic periodicals were analysed according to their type, purpose, contents, publisher, regularity, language, starting date and place of publication, and other features.

    2014-01-01

    This project aims to improve astronomy education at the high school level, and to increase awareness in astronomy for pre-university students, on an international scale. In 2013, the WorldWide Telescope Ambassadors Program began a collaboration with the International Olympiad in Astronomy and Astrophysics (IOAA), which was held in the city of Volos, Greece in August 2013. Now at its VIIth edition, IOAA is the largest annual astronomy competition for high school students, and it consists of one team task and three individual ones - Theoretical, Data Analysis, and Observational. Each of the participating countries (35 in 2013, compared to 21 in 2007) is responsible for selecting up to five representative students for the International round. IOAA is meant to promote future collaborations between these students, and to encourage friendships inside a global scientific community. Ana-Maria Constantin, a current Harvard undergraduate student and a former medalist of IOAA, represented WorldWide Telescope Ambassadors in Greece by giving a talk on the advantages of using WWT as a tool for research and education. As a result, the President and the International Board of the Olympiad have expressed support for including WWT in the competition for future editions. WWTA is working with the Organizing Board for next year’s competition in Romania, to include WWT as a testing tool. This poster will summarize key points from the WWTA presentation in Greece, present ideas for WWT-based activities in future IOAA competitions, and outline plans for new collaborations from representatives of Sri Lanka, Poland, Bangladesh, and Colombia. Given the positive feedback we have received after the presentation in Greece, we are also considering future implementations of WWT in summer research camps for high school students, such as the Summer Science Program.

    2013-01-01

    Mentoring, for physicians and surgeons in training, is advocated as an essential adjunct in work-based learning, providing support in career and non-career related issues. The World Wide Web (WWW) has evolved, as a technology, to become more interactive and person centric, tailoring itself to the individual needs of the user. This changing technology may open new avenues to foster mentoring in medicine. DESIGN, SYSTEMATIC REVIEW, MAIN OUTCOME MEASURES: A search of the MEDLINE database from 1950 to 2012 using the PubMed interface, combined with manual cross-referencing was performed using the following strategy: ("mentors"[MeSH Terms] OR "mentors"[All Fields] OR "mentor"[All Fields]) AND ("internet"[MeSH Terms] OR "internet"[All Fields]) AND ("medicine"[MeSH Terms] OR "medicine"[All Fields]) AND ("humans"[MeSH Terms] AND English[lang]). Abstracts were screened for relevance (UJ) to the topic; eligibility for inclusion was simply on screening for relevance to online mentoring and web-based technologies. Forty-five papers were found, of which 16 were relevant. All studies were observational in nature. To date, all medical mentoring applications utilizing the World Wide Web have enjoyed some success limited by Web 1.0 and 2.0 technologies. With the evolution of the WWW through 1.0, 2.0 and 3.0 generations, the potential for meaningful tele- and distance mentoring has greatly improved. Some engagement has been made with these technological advancements, however further work is required to fully realize the potential of these technologies.

    Orthotopic liver transplant (OLTx) has evolved to a successful surgical management for end-stage liver diseases. Awareness and information about OLTx is an important tool in assisting OLTx recipients and people supporting them, including non-transplant clinicians. The study aimed to investigate the nature and quality of liver transplant-related patient information on the World Wide Web. Four common search engines were used to explore the Internet by using the key words 'Liver transplant'. The URL (unique resource locator) of the top 50 returns was chosen as it was judged unlikely that the average user would search beyond the first 50 sites returned by a given search. Each Web site was assessed on the following categories: origin, language, accessibility and extent of the information. A weighted Information Score (IS) was created to assess the quality of clinical and educational value of each Web site and was scored independently by three transplant clinicians. The Internet search performed with the aid of the four search engines yielded a total of 2,255,244 Web sites. Of the 200 possible sites, only 58 Web sites were assessed because of repetition of the same Web sites and non-accessible links. The overall median weighted IS was 22 (IQR 1 - 42). Of the 58 Web sites analysed, 45 (77%) belonged to USA, six (10%) were European, and seven (12%) were from the rest of the world. The median weighted IS of publications originating from Europe and USA was 40 (IQR = 22 - 60) and 23 (IQR = 6 - 38), respectively. Although European Web sites produced a higher weighted IS [40 (IQR = 22 - 60)] as compared with the USA publications [23 (IQR = 6 - 38)], this was not statistically significant (p = 0.07). Web sites belonging to the academic institutions and the professional organizations scored significantly higher with a median weighted IS of 28 (IQR = 16 - 44) and 24(12 - 35), respectively, as compared with the commercial Web sites (median = 6 with IQR of 0 - 14, p = .001).

    Full Text Available Two methods were employed in this study of the use of the World Wide Web by business: first, a sample of 300 businesses with Web sites, across a wide range of industry types, was examined, by selecting (rather than sampling companies from the Yahoo! directory. The sites were investigated in relation to several areas - the purpose of the Web site, the use being made of electronic mail and the extent to which multi-media was being utilised. In addition, any other aspects of the site which were designed to make it more interesting to potential customers were also noted. Secondly, an electronic-mail questionnaire was sent to 222 of the 300 companies surveyed: that is, those that provided an e-mail address for contact. 14 were returned immediately due to unknown addresses or technical problems. Of the remaining 208, 102 replies were received, five of which were of no relevance, leaving 97 completed questionnaires to examine; a response rate of 47%, which is surprisingly good for a survey of this kind.

    1999-03-01

    We present here the design key concepts of WEBSLIDE, a software project whose objective is to provide a simple, cheap and efficient solution for showing slides during lessons in computer labs. In fact, WEBSLIDE allows the video monitors of several client machines (the "STUDENTS") to be synchronously updated by the actions of a particular client machine, called the "INSTRUCTOR." The system is based on the World Wide Web and the software components of WEBSLIDE mainly consists in a WWW server, browsers and small Cgi-Bill scripts. What makes WEBSLIDE particularly appealing for small educational institutions is that WEBSLIDE is built with "off the shelf" products: it does not involve using a specifically designed program but any Netscape browser, one of the most popular browsers available on the market, is sufficient. Another possible use is to use our system to implement "guided automatic tours" through several pages or Intranets internal news bulletins: the company Web server can broadcast to all employees relevant information on their browser.

  1. The world wide web: exploring a new advertising environment.

    Johnson, C R; Neath, I

    1999-01-01

    The World Wide Web currently boasts millions of users in the United States alone and is likely to continue to expand both as a marketplace and as an advertising environment. Three experiments explored advertising in the Web environment, in particular memory for ads as they appear in everyday use across the Web. Experiments 1 and 2 examined the effect of advertising repetition on the retention of familiar and less familiar brand names, respectively. Experiment 1 demonstrated that repetition of a banner ad within multiple web pages can improve recall of familiar brand names, and Experiment 2 demonstrated that repetition can improve recognition of less familiar brand names. Experiment 3 directly compared the retention of familiar and less familiar brand names that were promoted by static and dynamic ads and demonstrated that the use of dynamic advertising can increase brand name recall, though only for familiar brand names. This study also demonstrated that, in the Web environment, much as in other advertising environments, familiar brand names possess a mnemonic advantage not possessed by less familiar brand names. Finally, data regarding Web usage gathered from all experiments confirm reports that Web usage among males tends to exceed that among females.

    2016-01-01

    The purpose of this study was to describe the type and quality of health information about infant gastroesophageal reflux (GER) that a parent may find on the World Wide Web. The data collection tool included evaluation of Web site quality and infant GER-specific content on the 30 sites that met the inclusion criteria. The most commonly found content categories in order of frequency were management strategies, when to call a primary care provider, definition, and clinical features. The most frequently mentioned strategies included feeding changes, infant positioning, and medications. Thirteen of the 30 Web sites included information on both GER and gastroesophageal reflux disease. Mention of the use of medication to lessen infant symptoms was found on 15 of the 30 sites. Only 10 of the 30 sites included information about parent support and coping strategies. Pediatric nurse practitioners (PNPs) should utilize well-child visits to address the normalcy of physiologic infant GER and clarify any misperceptions parents may have about diagnosis and the role of medication from information they may have found on the Internet. It is critical for PNPs to assist in the development of Web sites with accurate content, advise parents on how to identify safe and reliable information, and provide examples of high-quality Web sites about child health topics such as infant GER.

    The purpose of this study was to explore and describe the type and quality of information on infantile colic that a parent might access on the World Wide Web. Two checklists were used to evaluate the quality indicators of 24 Web sites and the colic-specific content. Fifteen health information Web sites met more of the quality parameters than the nine commercial sites. Eight Web sites included information about colic and infant abuse, with six being health information sites. The colic-specific content on 24 Web sites reflected current issues and controversies; however, the completeness of the information in light of current evidence varied among the Web sites. Strategies to avoid complications of parental stress or infant abuse were not commonly found on the Web sites. Pediatric professionals must guide parents to reliable colic resources that also include emotional support and understanding of infant crying. A best evidence guideline for the United States would eliminate confusion and uncertainty about which colic therapies are safe and effective for parents and professionals.

  4. Geological problems in radioactive waste isolation - A world wide review

    Energy Technology Data Exchange (ETDEWEB)

    1991-06-01

    The problem of isolating radioactive wastes from the biosphere presents specialists in the earth sciences with some of the most complicated problems they have ever encountered. This is especially true for high-level waste (HLW), which must be isolated in the underground and away from the biosphere for thousands of years. The most widely accepted method of doing this is to seal the radioactive materials in metal canisters that are enclosed by a protective sheath and placed underground in a repository that has been carefully constructed in an appropriate rock formation. Much new technology is being developed to solve the problems that have been raised, and there is a continuing need to publish the results of new developments for the benefit of all concerned. Table 1 presents a summary of the various formations under investigation according to the reports submitted for this world wide review. It can be seen that in those countries that are searching for repository sites, granitic and metamorphic rocks are the prevalent rock type under investigation. Six countries have developed underground research facilities that are currently in use. All of these investigations are in saturated systems below the water table, except the United States project, which is in the unsaturated zone of a fractured tuff.

    Full Text Available The transition of traditional library collections to digital or virtual collections presented the librarian with new opportunities. The Internet, Web en-vironment and associated sophisticated tools have given the librarian a new dynamic role to play and serve the new information based society in bet-ter ways than hitherto. Because of the powerful features of Web i.e. distributed, heterogeneous, collaborative, multimedia, multi-protocol, hyperme-dia-oriented architecture, World Wide Web has revolutionized the way people access information, and has opened up new possibilities in areas such as digital libraries, virtual libraries, scientific information retrieval and dissemination. Not only the world is becoming interconnected, but also the use of Internet and Web has changed the fundamental roles, paradigms, and organizational culture of libraries and librarians as well. The article describes the limitless scope of Internet and Web, the existence of the librarian in the changing environment, parallelism between information sci-ence and information technology, librarians and intelligent agents, working of intelligent agents, strengths, weaknesses, threats and opportunities in-volved in the relationship between librarians and the Web. The role of librarian in Internet and Web environment especially as intermediary, facilita-tor, end-user trainer, Web site builder, researcher, interface designer, knowledge manager and sifter of information resources is also described.

    Full Text Available Some content in multimedia resources can depict or evoke certain emotions in users. The aim of Emotional Information Retrieval (EmIR and of our research is to identify knowledge about emotional-laden documents and to use these findings in a new kind of World Wide Web information service that allows users to search and browse by emotion. Our prototype, called Media EMOtion SEarch (MEMOSE, is largely based on the results of research regarding emotive music pieces, images and videos. In order to index both evoked and depicted emotions in these three media types and to make them searchable, we work with a controlled vocabulary, slide controls to adjust the emotions’ intensities, and broad folksonomies to identify and separate the correct resource-specific emotions. This separation of so-called power tags is based on a tag distribution which follows either an inverse power law (only one emotion was recognized or an inverse-logistical shape (two or three emotions were recognized. Both distributions are well known in information science. MEMOSE consists of a tool for tagging basic emotions with the help of slide controls, a processing device to separate power tags, a retrieval component consisting of a search interface (for any topic in combination with one or more emotions and a results screen. The latter shows two separately ranked lists of items for each media type (depicted and felt emotions, displaying thumbnails of resources, ranked by the mean values of intensity. In the evaluation of the MEMOSE prototype, study participants described our EmIR system as an enjoyable Web 2.0 service.

  8. Enhanced photosynthetic efficiency in trees world-wide by rising atmospheric CO2 levels

    The atmospheric CO2 concentration is increasing rapidly due to anthropogenic emissions but the effect on the Earth's biosphere is poorly understood. The ability of the biosphere to fix CO2 through photosynthesis will determine future atmospheric CO2 concentrations as well as future productivity of crops and forests. Manipulative CO2 enrichment experiments (e.g. FACE) are limited to (i) short time spans, (ii) few locations and (iii) large step increases in [CO2]. Here, we apply new stable isotope methodology to tree-ring archives, to study the effect of increasing CO2 concentrations retrospectively during the past centuries. We cover the whole [CO2] increase since industrialization, and sample trees with global distribution. Instead of isotope ratios of whole molecules, we use intramolecular isotope distributions, a new tool for tree-ring analysis with decisive advantages. In experiments on annual plants, we have found that the intramolecular distribution of deuterium (equivalent to ratios of isotopomer abundances) in photosynthetic glucose depends on growth [CO2] and reflects the metabolic flux ratio of photosynthesis to photorespiration. By applying this isotopomer methodology to trees from Oak Ridge FACE experiment, we show that this CO2 response is present in trees on the leaf level. This CO2 dependence constitutes a physiological signal, which is transferred to the wood of the tree rings. In trees from 13 locations on all continents the isotopomer ratio of tree-ring cellulose is correlated to atmospheric [CO2] during the past 200 years. The shift of the isotopomer ratio is universal for all 12 species analyzed, including both broad-leafed trees and conifers. Because the trees originate from sites with widely differing D/H ratios of precipitation, the generality of the response demonstrates that the signal is independent of the source isotope ratio, because it is encoded in an isotopomer abundance ratio. This decoupling of climate signals and physiological

    `Astronomy On-Line' will connect students all over Europe Astronomy On-Line is a major, all-European project that will take place in conjunction with the 4th European Week for Scientific and Technological Culture later this year. It is based on intensive use of the World-Wide-Web (WWW) and represents the first large-scale attempt in the world to bring together pupils and their teachers all over one continent to explore challenging scientific questions, using modern communication tools, both for obtaining and for communicating information. The programme will be carried out in a collaboration between the European Association for Astronomy Education (EAAE) [1] and the European Southern Observatory, and together with the European Commission (EC). The active phase of Astronomy On-Line will start on October 1 and reach a climax on November 18 - 22, 1996 . What is `Astronomy On-Line'? In this project, a large number of students and their teachers at schools all over Europe, together with professional and amateur astronomers and others interested in astronomy, will become associated in a unique experience that makes intensive use of the vast possibilities of the World-Wide-Web (WWW). Although the exact number of participants will not be known until the beginning of October, it is expected to run into thousands, possibly many more. The unusual size and scope of Astronomy On-Line will contribute to make it an important all-European media event. The central idea is that the participants, through the WWW, will `meet' in a `marketplace' where a number of different `shops' will be available, each of which will tempt them with a number of exciting and educational `events', carefully prepared to cater for different age groups, from 12 years upwards. The events will cover a wide spectrum of activities, some of which will be timed to ensure the proper progression of this very complex project through its main phases.

    1995-01-01

    The explosive growth of the World-Wide Web (WWW) in the past year has made it feasible to provide interactive graphical tools to assist scientists in locating planetary images. The highest available resolution images of any site of interest can be quickly found on a map or plot, and, if online, displayed immediately on nearly any computer equipped with a color screen, an Internet connection, and any of the free WWW browsers. The same tools may also be of interest to educators, students, and the general public. Image finding tools have been implemented covering most of the solar system: Earth, Mars, and the moons and planets imaged by Voyager. The Mars image-finder, which plots the footprints of all the high-resolution Viking Orbiter images and can be used to display any that are available online, also contains a complete scrollable atlas and hypertext gazetteer to help locating areas. The Earth image-finder is linked to thousands of Shuttle images stored at NASA/JSC, and displays them as red dots on a globe. The Voyager image-finder plots images as dots, by longitude and apparent target size, linked to online images. The locator (URL) for the top-level page is http: //ic-www.arc.nasa.gov/ic/projects/bayes-group/Atlas/. Through the efforts of the Planetary Data System and other organizations, hundreds of thousands of planetary images are now available on CD-ROM, and many of these have been made available on the WWW. However, locating images of a desired site is still problematic, in practice. For example, many scientists studying Mars use digital image maps, which are one third the resolution of Viking Orbiter survey images. When they douse Viking Orbiter images, they often work with photographically printed hardcopies, which lack the flexibility of digital images: magnification, contrast stretching, and other basic image-processing techniques offered by off-the-shelf software. From the perspective of someone working on an experimental image processing technique for

    liposuctions and retromuscular reinjections. The advantage with regard to the medical procedures is greater stability over time and the greater precision of these muscular actions (one third of a muscle can be weakened for example) and the fat reinjections can be more stable. These procedures can be performed under local anesthesia. In cases of more advanced ageing, surgery offers new treatment possibilities that include, for the midface region, the concentric malar lift. It replaces, on the orbital rim, the sub-orbicularis oculi fat that has descended eccentrically as a result of the contractions of the orbicularis oculi muscle. The procedure, using the subperiosteal detachment plane, is therefore stable over time. At the same time, specific muscles are weakened. The aims of restoring fatty volumes and muscular tonuses are thus achieved. Similarly, in the neck, the platysma muscle is specifically weakened. Each area is studied in line with its specificities. For the first time, the skin tension of the facelift has no more to be maximum to treat the relief of the jawl line, of the palpebro malar groove and so on. The skin tension becomes moderate, just to remove the excess of skin. The relief is faded with the specific muscular and fatty action. The name of this new concept is Face Recurve.

  13. World-Wide Effort Produces Dramatic "Movie" of Cosmic Jet

    Science.gov (United States)

    2001-05-01

    Astronomers using a world-wide collection of radio telescopes, including the National Science Foundation's Very Long Baseline Array (VLBA) of the National Radio Astronomy Observatory (NRAO), have made a dramatic "movie" of a voracious, superdense neutron star repeatedly spitting out subatomic particles at nearly the speed of light into two narrow jets as it pulls material from a companion star. The movie shows these jets ejecting clouds of hot plasma that are then "zapped" by pulses of energy in the jets as they move away from the neutron star. Frame from Radio-Telescope 'Movie' of Scorpius X-1 "We have directly measured the speed of energy flow in a cosmic jet for the first time," said Ed Fomalont, an astronomer at the NRAO in Charlottesville, Virginia. Fomalont worked with Barry Geldzahler and Charles Bradshaw of George Mason University in Fairfax, Virginia. The astronomers used the VLBA, the NSF's Very Large Array (VLA) and the Green Bank 140-foot telescope, along with radio telescopes from the European VLBI Network, Australia, Japan and South Africa to record the double-star system's eruptions continuously for 56 hours. "This study is going to be extremely valuable in helping us understand a phenomenon that we see throughout the universe," Fomalont said. Cosmic jets of superfast particles are ejected from the cores of numerous galaxies. On a smaller scale, similar jets are ejected from binary-star systems closer to home, in our own Milky Way Galaxy. While the jets from galaxy cores are thought to be powered by supermassive black holes millions of times more massive than the Sun, the closer "microquasars" are powered by much smaller black holes or by neutron stars only a few times more massive than the sun. "Studying one of the closer, smaller examples will help us understand how they all work, including the bigger ones," Geldzahler said. "The jets coming from distant galaxies are harder to study because of their much greater distance and the slowness of their

    This study details my viewpoint on the experiences, lessons, and assessments of conducting a national study on care-seeking behavior for heart attack in the United States utilizing the World Wide Web. The Yale Heart Study (YHS) was funded by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health (NIH). Grounded on two prior studies, the YHS combined a Web-based interview survey instrument; ads placed on the Internet; flyers and posters in public libraries, senior centers, and rehabilitation centers; information on chat rooms; a viral marketing strategy; and print ads to attract potential participants to share their heart attack experiences. Along the way, the grant was transferred from Ohio State University (OSU) to Yale University, and significant administrative, information technology, and personnel challenges ensued that materially delayed the study's execution. Overall, the use of the Internet to collect data on care-seeking behavior is very time consuming and emergent. The cost of using the Web was approximately 31% less expensive than that of face-to-face interviews. However, the quality of the data may have suffered because of the absence of some data compared with interviewing participants. Yet the representativeness of the 1154 usable surveys appears good, with the exception of a dearth of African American participants. ©Angelo A Alonzo.

    Las Cumbres Observatory Global Telescope (LCOGT) is an organization dedicated to time-domain astronomy. To carry out the necessary observations in fields such as supernovae, extrasolar planets, small solar-system bodies, and pulsating stars, we have developed and are now deploying a set of robotic optical telescopes at sites around the globe. In this talk I will concentrate on the core of this network, consisting of up to 15 identical 1m telescopes deployed across multiple sites in both the northern and southern hemispheres. I will summarize the technical and performance aspect of these telescopes, including both their imaging and their anticipated spectroscopic capabilities. But I will also delve into the network organization, including communication among telescopes (to assure that observations are properly carried out), interactions among the institutions and scientists who will use the network (to optimize the scientific returns), and our funding model (which until now has relied entirely on one private donor, but will soon require funding from outside sources, if the full potential of the network is to be achieved).

    We present a new way of exploring your favorite Galaxy Zoo galaxies within the context of the sky using Microsoft Research's WorldWide Telescope. Galaxy Zoo has a fantastic community that is eager to learn and contribute to science through morphological classifications of galaxies. WorldWide Telescope is an interactive observatory that allows users to explore the sky. WorldWide Telescope uses images from the world's best telescopes, including the galaxies of the Sloan Digital Sky Survey. WorldWide Telescope provides a fantastic sense of size and distance that is hard to experience in Galaxy Zoo. Creating tours from favorite galaxies directly from Galaxy Zoo aims to solve this dilemma.The incorporation of Galaxy Zoo and WorldWide telescope provides a great resource for users to learn more about the galaxies they are classifying. Users can now explore the areas around certain galaxies and view information about that location from within WorldWide Telescope. Not only does this encourage self-motivated research but after tours are created they can be shared with anyone. We hope this will help spread citizen science to different audiences via email, Facebook, and Twitter.Without the WorldWide Telescope team at Microsoft Research this project would not have been possible. Please go start exploring at http://wwt.galaxyzoo.org. This project was funded through the Microsoft Research Academic Program.

    The world-wide sensor web has become a very useful technique for monitoring the physical world at spatial and temporal scales that were previously impossible. Yet we believe that the full potential of sensor web has thus far not been revealed. In order to harvest the world-wide sensor web's full potential, a geospatial cyberinfrastructure is needed to store, process, and deliver large amount of sensor data collected worldwide. In this paper, we first define the issue of the sensor web long tail followed by our view of the world-wide sensor web architecture. Then, we introduce the Geospatial Cyberinfrastructure for Environmental Sensing (GeoCENS) architecture and explain each of its components. Finally, with demonstration of three real-world powered-by-GeoCENS sensor web applications, we believe that the GeoCENS architecture can successfully address the sensor web long tail issue and consequently realize the world-wide sensor web vision.

    To identify and describe advantages, challenges, and ethical considerations of web based behavioural data collection. This discussion is based on the authors' experiences in survey development and study design, respondent recruitment, and internet research, and on the experiences of others as found in the literature. The advantages of using the world wide web to collect behavioural data include rapid access to numerous potential respondents and previously hidden populations, respondent openness and full participation, opportunities for student research, and reduced research costs. Challenges identified include issues related to sampling and sample representativeness, competition for the attention of respondents, and potential limitations resulting from the much cited "digital divide", literacy, and disability. Ethical considerations include anonymity and privacy, providing and substantiating informed consent, and potential risks of malfeasance. Computer mediated communications, including electronic mail, the world wide web, and interactive programs will play an ever increasing part in the future of behavioural science research. Justifiable concerns regarding the use of the world wide web in research exist, but as access to, and use of, the internet becomes more widely and representatively distributed globally, the world wide web will become more applicable. In fact, the world wide web may be the only research tool able to reach some previously hidden population subgroups. Furthermore, many of the criticisms of online data collection are common to other survey research methodologies.

  4. Efficacy of the World Wide Web in K-12 environmental education

    Science.gov (United States)

    York, Kimberly Jane

    1998-11-01

    Despite support by teachers, students, and the American public in general, environmental education is not a priority in U.S. schools. Teachers face many barriers to integrating environmental education into K--12 curricula. The focus of this research is teachers' lack of access to environmental education resources. New educational reforms combined with emerging mass communication technologies such as the Internet and World Wide Web present new opportunities for the infusion of environmental content into the curriculum. New technologies can connect teachers and students to a wealth of resources previously unavailable to them. However, significant barriers to using technologies exist that must be overcome to make this promise a reality. Web-based environmental education is a new field and research is urgently needed. If teachers are to use the Web meaningfully in their classrooms, it is essential that their attitudes and perceptions about using this new technology be brought to light. Therefore, this exploratory research investigates teachers' attitudes toward using the Web to share environmental education resources. Both qualitative and quantitative methods were used to investigate this problem. Two surveys were conducted---self-administered mail survey and a Web-based online survey---to elicit teachers perceptions and comments about environmental education and the Web. Preliminary statistical procedures including frequencies, percentages and correlational measures were performed to interpret the data. In-depth interviews and participant-observation methods were used during an extended environmental education curriculum development project with two practicing teachers to gain insights into the process of creating curricula and placing it online. Findings from the both the mail survey and the Web-based survey suggest that teachers are interested in environmental education---97% of respondents for each survey agreed that environmental education should be taught in K

    A study has been made of the phenomena occurring in the neighbourhood of a growing crystal-face, with the help of several methods based on interferometric observation. If the system is considered at a given moment, it is possible to express the growth rate of the crystal in two ways: 1) using the origin of the solute contributing to the growth, by application of Fick's law modified in certain cases by a correction factor involving the absolute value of the concentration near the crystal face. 2) directly, using the supersaturation in the crystal-face neighbourhood. On the other hand, if an attempt is made to take into account the changes in growth rate with time, it is seen that this rate is not dependent on diffusion phenomena, but that the convection currents in the solution play an important role. (author) [French] Les phenomenes qui ont lieu dans la solution au voisinage d'un cristal en voie de croissance ont ete etudies grace a plusieurs methodes d'observation interferometriques. Si l'on considere la preparation a un instant donne, il est possible d'exprimer la vitesse de croissance du cristal de deux manieres: 1) a partir de la provenance du solute necessaire a la croissance, par application de l'equation de Fick moyennant, dans certains cas, un facteur correctif faisant intervenir la valeur absolue de la concentration au voisinage de la face, 2) directement a partir de la sursaturation qui regne pres de la face. Par contre, si l'on essaie de rendre compte de l'evolution de la vitesse de croissance au cours du temps, on voit que celle-ci n'est pas commandee par les phenomenes de diffusion, mais que les courants de convection qui existent dons la solution jouent un role important.

    The World Wide Web ("the Web") is a macrocosm of resources that can be overwhelming. Often the sheer volume of material available causes one to give up in despair before finding information of any use. The Web is such a popular resource that it cannot be ignored. Two of the biggest challenges to finding good information on the Web are knowing where to start and judging whether the information gathered is pertinent and credible. This article addresses these two challenges and introduces the reader to a variety of ophthalmology and vision science resources on the World Wide Web.

    Nelson, Michael L.; Bianco, David J.

    1994-01-01

    NASA Langley Research Center (LaRC) began using the World Wide Web (WWW) in the summer of 1993, becoming the first NASA installation to provide a Center-wide home page. This coincided with a reorganization of LaRC to provide a more concentrated focus on technology transfer to both aerospace and non-aerospace industry. Use of the WWW and NCSA Mosaic not only provides automated information dissemination, but also allows for the implementation, evolution and integration of many technology transfer applications. This paper describes several of these innovative applications, including the on-line presentation of the entire Technology Opportunities Showcase (TOPS), an industrial partnering showcase that exists on the Web long after the actual 3-day event ended. During its first year on the Web, LaRC also developed several WWW-based information repositories. The Langley Technical Report Server (LTRS), a technical paper delivery system with integrated searching and retrieval, has proved to be quite popular. The NASA Technical Report Server (NTRS), an outgrowth of LTRS, provides uniform access to many logically similar, yet physically distributed NASA report servers. WWW is also the foundation of the Langley Software Server (LSS), an experimental software distribution system which will distribute LaRC-developed software with the possible phase-out of NASA's COSMIC program. In addition to the more formal technology distribution projects, WWW has been successful in connecting people with technologies and people with other people. With the completion of the LaRC reorganization, the Technology Applications Group, charged with interfacing with non-aerospace companies, opened for business with a popular home page.

  13. GeoCENS: A Geospatial Cyberinfrastructure for the World-Wide Sensor Web

    Directory of Open Access Journals (Sweden)

    Steve H.L. Liang

    2013-10-01

    Full Text Available The world-wide sensor web has become a very useful technique for monitoring the physical world at spatial and temporal scales that were previously impossible. Yet we believe that the full potential of sensor web has thus far not been revealed. In order to harvest the world-wide sensor web’s full potential, a geospatial cyberinfrastructure is needed to store, process, and deliver large amount of sensor data collected worldwide. In this paper, we first define the issue of the sensor web long tail followed by our view of the world-wide sensor web architecture. Then, we introduce the Geospatial Cyberinfrastructure for Environmental Sensing (GeoCENS architecture and explain each of its components. Finally, with demonstration of three real-world powered-by-GeoCENS sensor web applications, we believe that the GeoCENS architecture can successfully address the sensor web long tail issue and consequently realize the world-wide sensor web vision.

    Directory of Open Access Journals (Sweden)

    James F. Aiton

    1994-01-01

    Full Text Available The rapid expansion occurring in World-Wide Web activity is beginning to make the concepts of ‘global hypermedia’ and ‘universal document readership’ realistic objectives of the new revolution in information technology. One consequence of this increase in usage is that educators and students are becoming more aware of the diversity of the knowledge base which can be accessed via the Internet. Although computerised databases and information services have long played a key role in bioinformatics these same resources can also be used to provide core materials for teaching and learning. The large datasets and arch ives th at have been compiled for biomedical research can be enhanced with the addition of a variety of multimedia elements (images. digital videos. animation etc.. The use of this digitally stored information in structured and self-directed learning environments is likely to increase as activity across World-Wide Web increases.

  16. The World-Wide Web past present and future, and its application to medicine

    CERN Document Server

    Sendall, D M

    1997-01-01

    The World-Wide Web was first developed as a tool for collaboration in the high energy physics community. From there it spread rapidly to other fields, and grew to its present impressive size. As an easy way to access information, it has been a great success, and a huge number of medical applications have taken advantage of it. But there is another side to the Web, its potential as a tool for collaboration between people. Medical examples include telemedicine and teaching. New technical developments offer still greater potential in medical and other fields. This paper gives some background to the early development of the World-Wide Web, a brief overview of its present state with some examples relevant to medicine, and a look at the future.

    We model the commercial World Wide Web as a directed graph that emerges as the equilibrium of a game in which utility maximizing websites purchase (advertising) in-links from each other while also setting the price of these links. In equilibrium, higher content sites tend to purchase more advertising links (mirroring the Dorfman-Steiner rule) while selling less advertising links themselves. As such, there seems to be specialization across sites in revenue models: high content sites tend to ea...

  19. Do We Need to Impose More Regulation Upon the World Wide Web? -A Metasystem Analysis

    Directory of Open Access Journals (Sweden)

    John P. van Gigch

    2000-01-01

    Full Text Available Every day a new problem attributable to the World Wide Web's lack of formal structure and/or organization is made public. What arguably could be represented as one of its main strengths is rapidly turning out to be one of its most flagrant weaknesses. The intent of this article is to show the need to establish a more formal organization than presently exists over the World Wide Web. (This article will use the terms the Internet and Cyberspace interchangeably. It is proposed that this formal organization take the form of a metacontrol system--to be explained-- and rely, at least in part, for this control to self-regulate. The so-called metasystem system would be responsible for preventing some of the unanticipated situations that take place in cyberspace and that, due to the web's lack of maturity, have not been encountered heretofore. Some activities, such as the denial-of-service (DoS attacks, may well be illicit. Others, like the question of establishing a world-wide democratic board to administer the Internet's address system, are so new that there are no technical, legal or political precedents to ensure its design will succeed. What is needed is a formal, over-arching control system, i.e. a "metasystem," to arbitrate over controversies, decide on the legality of new policies and, in general, act as a metalevel controller over the activities of the virtual community called Cyberspace. The World Wide Web Consortium has emerged as a possible candidate for this role.This paper uses control theory to define both the problem and the proposed solution. Cyberspace lacks a metacontroller that can be used to resolve the many problems that arise when a new organizational configuration, such as the Internet, is created and when questions surface about the extent to which new activities interfere with individual or corporate freedoms.

    2002-06-01

    Color is the most powerful building material of visual imagery on the World Wide Web. It must function successfully as it has done historically in traditional two-dimensional media, as well as address new challenges presented by this electronic medium. The psychological, physiological, technical and aesthetic effects of color have been redefined by the unique requirements of the electronic transmission of text and images on the Web. Color simultaneously addresses each of these dimensions in this electronic medium.

    “As Bill Gates and Steve Case proclaim the global omnipresence of the Internet, the majority of non-Western nations and 97 per cent of the world's population remain unconnected to the net for lack of money, access, or knowledge. This exclusion of so vast a share of the global population from the Internet sharply contradicts the claims of those who posit the World Wide Web as a ‘universal' medium of egalitarian communication.” (Trend 2001:2)

  6. Embedded Web Technology: Applying World Wide Web Standards to Embedded Systems

    Science.gov (United States)

    Ponyik, Joseph G.; York, David W.

    2002-01-01

    Embedded Systems have traditionally been developed in a highly customized manner. The user interface hardware and software along with the interface to the embedded system are typically unique to the system for which they are built, resulting in extra cost to the system in terms of development time and maintenance effort. World Wide Web standards have been developed in the passed ten years with the goal of allowing servers and clients to intemperate seamlessly. The client and server systems can consist of differing hardware and software platforms but the World Wide Web standards allow them to interface without knowing about the details of system at the other end of the interface. Embedded Web Technology is the merging of Embedded Systems with the World Wide Web. Embedded Web Technology decreases the cost of developing and maintaining the user interface by allowing the user to interface to the embedded system through a web browser running on a standard personal computer. Embedded Web Technology can also be used to simplify an Embedded System's internal network.

  7. World Wide Web voted most wonderful wonder by web-wide world

    CERN Multimedia

    The results are in, and the winner is...the World Wide Web! An online survey conducted by the CNN news group ranks the World Wide Web-invented at CERN--as the most wonderful of the seven modern wonders of the world. (See Bulletin No. 49/2006.) There is currently no speculation about whether they would have had the same results had they distributed the survey by post. The World Wide Web won with a whopping 50 per cent of the votes (3,665 votes). The runner up was CERN again, with 16 per cent of voters (1130 votes) casting the ballot in favour of the CERN particle accelerator. Stepping into place behind CERN and CERN is 'None of the Above' with 8 per cent of the votes (611 votes), followed by the development of Dubai (7%), the bionic arm (7%), China's Three Gorges Damn (5%), The Channel Tunnel (4%), and France's Millau viaduct (3%).

    Science.gov (United States)

    Hunter, William John Forbes

    1998-12-01

    This thesis describes an action research investigation of improvements to instruction in General Chemistry at Purdue University. Specifically, the study was conducted to guide continuous reform of curriculum materials delivered via the World Wide Web by involving students, instructors, and curriculum designers. The theoretical framework for this study was based upon constructivist learning theory and knowledge claims were developed using an inductive analysis procedure. This results of this study are assertions made in three domains: learning chemistry content via the World Wide Web, learning about learning via the World Wide Web, and learning about participation in an action research project. In the chemistry content domain, students were able to learn chemical concepts that utilized 3-dimensional visualizations, but not textual and graphical information delivered via the Web. In the learning via the Web domain, the use of feedback, the placement of supplementary aids, navigation, and the perception of conceptual novelty were all important to students' use of the Web. In the participation in action research domain, students learned about the complexity of curriculum. development, and valued their empowerment as part of the process.

  9. What is WorldWide Telescope, and Why Should Researchers Care?

    Science.gov (United States)

    Goodman, Alyssa A.

    2016-01-01

    As of 2015, about 20 million people have downloaded the computer program called "WorldWide Telescope," and even more have accessed it via the web, at http://worldwidetelescope.org. But, the vast majority of these millions are not professional astronomers. This talk will explain why WorldWide Telescope (WWT) is also a powerful tool for research astronomers. I will focus on how WWT can be, and is, being built-in to Journals, and into day-to-day research environments. By way of example, I will show how WWT already: allows users to display images, including those in Journals, in the context of multi-wavelength full-sky imagery; allows for the display of which parts of the Sky have been studied, when, how, and for what reason (see http://adsass.org); allows, via right-click, immediate access to ADS, SIMBAD, and other professional research tools. I will also highlight new work, currently in development, that is using WWT as a tool for observation planning, and as a display mode for advanced high-dimensional data visualization tools, like glue (see http://glueviz.org). WWT is now well-known in the education community (see http://wwtambassadors.org), so the explicit goal of this talk will be to make researchers more aware of its full power. I will explain how WWT transitioned, over 8 years, from a Microsoft Research project to its current open-source state (see https://github.com/WorldWideTelescope), and I will conclude with comments on the future of WWT, and its relationship to how research should be carried out in the future (see http://tinyurl.com/aas-potf).

    Georgeot, Bertrand; Giraud, Olivier; Shepelyansky, Dima L

    2010-05-01

    We study numerically the spectrum and eigenstate properties of the Google matrix of various examples of directed networks such as vocabulary networks of dictionaries and university World Wide Web networks. The spectra have gapless structure in the vicinity of the maximal eigenvalue for Google damping parameter α equal to unity. The vocabulary networks have relatively homogeneous spectral density, while university networks have pronounced spectral structures which change from one university to another, reflecting specific properties of the networks. We also determine specific properties of eigenstates of the Google matrix, including the PageRank. The fidelity of the PageRank is proposed as a characterization of its stability.

    Garelli, S.; Giordano, S.; Piemontese, G.; Squarcia, S.

    1998-01-01

    We considered the possibility of using the simulation code FLUKA, in the framework of TERA. We provided a window under World Wide Web in which an interactive version of the code is available. The user can find instructions for the installation, an on-line FLUKA manual and interactive windows for inserting all the data required by the configuration running file in a very simple way. The database choice allows a more versatile use for data verification and update, recall of old simulations and comparison with selected examples. A completely new tool for geometry drawing under Java has also been developed. (authors)

    1991-01-01

    Irradiation (ionizing radiation) of various foods is growing in popularity internationally. For example, it is used as a substitute for the use of post-harvest pesticides. This trend has served to intensify research on the identification of irradiated foods. The first Research Co-ordinated Meeting on Analytical Detection Method for Irradiated Foods was held in Poland under the sponsorship of FAO/IAEA in 1990 in order to solve problems related to the international trade of irradiated foods and to ensure their correct labelling in the market. In this review, the world-wide advances in the irradiation of food and its identification are introduced and discussed. (author)

    Sarna, Linda; Bialous, Stella Aguinaga

    2012-01-01

    With the advent of the World Wide Web, historic images previously having limited distributions are now widely available. As tobacco use has evolved, so have images of nurses related to smoking. Using a systematic search, the purpose of this article is to describe types of images of nurses and smoking available on the World Wide Web. Approximately 10,000 images of nurses and smoking published over the past century were identified through search engines and digital archives. Seven major themes were identified: nurses smoking, cigarette advertisements, helping patients smoke, "naughty" nurse, teaching women to smoke, smoking in and outside of health care facilities, and antitobacco images. The use of nursing images to market cigarettes was known but the extent of the use of these images has not been reported previously. Digital archives can be used to explore the past, provide a perspective for understanding the present, and suggest directions for the future in confronting negative images of nursing.

    Muthukumarasamy, S; Osmani, Z; Sharpe, A; England, R J A

    2012-02-01

    This study aimed to assess the quality of information available on the World Wide Web for patients undergoing thyroidectomy. The first 50 web-links generated by internet searches using the five most popular search engines and the key word 'thyroidectomy' were evaluated using the Lida website validation instrument (assessing accessibility, usability and reliability) and the Flesch Reading Ease Score. We evaluated 103 of a possible 250 websites. Mean scores (ranges) were: Lida accessibility, 48/63 (27-59); Lida usability, 36/54 (21-50); Lida reliability, 21/51 (4-38); and Flesch Reading Ease, 43.9 (2.6-77.6). The quality of internet health information regarding thyroidectomy is variable. High ranking and popularity are not good indicators of website quality. Overall, none of the websites assessed achieved high Lida scores. In order to prevent the dissemination of inaccurate or commercially motivated information, we recommend independent labelling of medical information available on the World Wide Web.

    While research activities on osteoporosis grow constantly, no concise description of the global research architecture exists. Hence, we aim to analyze and depict the world-wide scientific output on osteoporosis combining bibliometric tools, density-equalizing mapping projections and gender analysis. Using the NewQIS platform, we analyzed all osteoporosis-related publications authored from 1900 to 2012 and indexed by the Web of Science. Bibliometric details were analyzed related to quantitative and semi-qualitative aspects. The majority of 57 453 identified publications were original research articles. The USA and Western Europe dominated the field regarding cooperation activity, publication and citation performance. Asia, Africa and South America played a minimal role. Gender analysis revealed a dominance of male scientists in almost all countries except Brazil. Although the scientific performance on osteoporosis is increasing world-wide, a significant disparity in terms of research output was visible between developed and low-income countries. This finding is particularly concerning since epidemiologic evaluations of future osteoporosis prevalences predict enormous challenges for the health-care systems in low-resource countries. Hence, our study underscores the need to address these disparities by fostering future research endeavors in these nations with the aim to successfully prevent a growing global burden related to osteoporosis.

  7. Use of World Wide Web-based directories for tracing subjects in epidemiologic studies.

    2000-11-01

    The recent availability of World Wide Web-based directories has opened up a new approach for tracing subjects in epidemiologic studies. The completeness of two World Wide Web-based directories (Canada411 and InfoSpace Canada) for subject tracing was evaluated by using a randomized crossover design for 346 adults randomly selected from respondents in an ongoing cohort study. About half (56.4%) of the subjects were successfully located by using either Canada411 or InfoSpace. Of the 43.6% of the subjects who could not be located using either directory, the majority (73.5%) were female. Overall, there was no clear advantage of one directory over the other. Although Canada411 could find significantly more subjects than InfoSpace, the number of potential matches returned by Canada411 was also higher, which meant that a longer list of potential matches had to be examined before a true match could be found. One strategy to minimize the number of potential matches per true match is to first search by InfoSpace with the last name and first name, then by Canada411 with the last name and first name, and finally by InfoSpace with the last name and first initial. Internet-based searches represent a potentially useful approach to tracing subjects in epidemiologic studies.

    2007-05-01

    This study was designed to ascertain the quality of patient information available on the World Wide Web on the topic of knee arthroscopy. For the purpose of quality analysis, we used a pool of 232 search results obtained from 7 different search engines. We used a modified assessment questionnaire to assess the quality of these Web sites. This questionnaire was developed based on similar studies evaluating Web site quality and includes items on illustrations, accessibility, availability, accountability, and content of the Web site. We also compared results obtained with different search engines and tried to establish the best possible search strategy to attain the most relevant, authentic, and adequate information with minimum time consumption. For this purpose, we first compared 100 search results from the single most commonly used search engine (AltaVista) with the pooled sample containing 20 search results from each of the 7 different search engines. The search engines used were metasearch (Copernic and Mamma), general search (Google, AltaVista, and Yahoo), and health topic-related search engines (MedHunt and Healthfinder). The phrase "knee arthroscopy" was used as the search terminology. Excluding the repetitions, there were 117 Web sites available for quality analysis. These sites were analyzed for accessibility, relevance, authenticity, adequacy, and accountability by use of a specially designed questionnaire. Our analysis showed that most of the sites providing patient information on knee arthroscopy contained outdated information, were inadequate, and were not accountable. Only 16 sites were found to be providing reasonably good patient information and hence can be recommended to patients. Understandably, most of these sites were from nonprofit organizations and educational institutions. Furthermore, our study revealed that using multiple search engines increases patients' chances of obtaining more relevant information rather than using a single search

  10. Clear-sky classification procedures and models using a world-wide data-base

    International Nuclear Information System (INIS)

    Younes, S.; Muneer, T.

    2007-01-01

    Clear-sky data need to be extracted from all-sky measured solar-irradiance dataset, often by using algorithms that rely on other measured meteorological parameters. Current procedures for clear-sky data extraction have been examined and compared with each other to determine their reliability and location dependency. New clear-sky determination algorithms are proposed that are based on a combination of clearness index, diffuse ratio, cloud cover and Linke's turbidity limits. Various researchers have proposed clear-sky irradiance models that rely on synoptic parameters; four of these models, MRM, PRM, YRM and REST2 have been compared for six world-wide-locations. Based on a previously-developed comprehensive accuracy scoring method, the models MRM, REST2 and YRM were found to be of satisfactory performance in decreasing order. The so-called Page radiation model (PRM) was found to underestimate solar radiation, even though local turbidity data were provided for its operation

    2002-08-01

    We simulate evolution of the World Wide Web from the dynamic rules incorporating growth, bias attachment, and rewiring. We show that the emergent double-hierarchical structure with distinct distributions of out- and in-links is comparable with the observed empirical data when the control parameter (average graph flexibility β) is kept in the range β=3-4. We then explore the Web graph by simulating (a) Web crawling to determine size and depth of connected components, and (b) a random walker that discovers the structure of connected subgraphs with dominant attractor and promoter nodes. A random walker that adapts its move strategy to mimic local node linking preferences is shown to have a short access time to "important" nodes on the Web graph.

  12. The World Wide Web: A Web Even a Fly Would Love

    Bryson, E.

    Ever since my introduction to the World Wide Web (WWW), it's been love at first byte. Searching on the WWW is similar to being able to go to a public library and allow yourself to be transported to any other book or library around the world by looking at a reference or index and clicking your heels together like Dorothy did in "The Wizard of Oz", only the clicking is done with a computer mouse. During this presentation, we will explore the WWW protocols which allow clients and servers to communicate on the Internet. We will demonstrate the ease with which users can navigate the virtual tidal wave of information available with a mere click of a button. In addition, the workshop will discuss the revolutionary aspects of this network information system and how it's impacting our libraries as a primary mechanism for rapid dissemination of knowledge.

    During the latest 20 years, the crucial progress has been made in the field of treatment for Budd-Chiari syndrome (BCS)in China with therapeutic methods transferring from surgical to interventional and achieving successful rate of 96%. Our unique contribution to the BCS interventional therapy should have made ourselves proud for being as a superior world position on account of large number of cases, abundant therapeutic contents and consummate skills. What a pity is that our achievement was not appreciated by international colleagues because of only a few papers published in SCI journals. So that, Chinese scholars ought to have doing more necessarily through diligently learning English, doing long term follow-up and performing more basic researches and actively joining international academic exchanges, let our good experiences of treatment for BCS be introduced to the world-wide.

    1997-12-31

    Wind energy is now being deployed world-wide at a rapidly increasing rate and the International Energy Agency (IEA) has a changing role in its growth. IEA was founded in 1974 within the framework of the Organization for Economic Cooperation and Development (OECD) to collaborate on comprehensive international energy programs. IEA membership consists of eighteen parties from sixteen countries and the European Commission. Recently there has been increasing interest in IEA participation from both OECD and non-OECD countries. Non-OECD countries participating in various IEA Agreements include: China, India, Israel, Korea, and Russia. Because of its diverse international makeup, the IEA is viewed as a source of reliable technical and economic information. The World Bank has approached the Executive Committee for Wind Energy R & D, through the IEA Renewable Energy Working Party, to assist in the expansion of wind deployment. In addition, IEA is moving from R & D programs to include tracking of implementation incentives offered by its members.

    2002-09-01

    The World Wide Web (WWW) is continuing to grow exponentially both in terms of numbers of users and numbers of web pages. There is a trend toward the increasing use of the WWW for medical educational purposes, both among physicians and patients alike. The multimedia capabilities of this evolving medium are particularly relevant to visual medical specialties such as dermatology. The origins of information consumerism on the WWW are examined, and the public health issues surrounding dermatologic information and misinformation, and how consumers navigate through the WWW are reviewed. The economic realities of medical information as a "capital good," and the impact this has on dermatologic information sources on the WWW are also discussed.Finally, strategies for guiding consumers and ourselves toward credible medical information sources on the WWW are outlined.

    2002-01-01

    The World Wide Web is increasingly important for medical education. Internet served pages may also be used on a local hard disk or CD-ROM without a network or server. This allows authors to reuse existing content and provide access to users without a network connection. CD-ROM offers several advantages over network delivery of Web pages for several applications. However, creating Web pages for CD-ROM requires careful planning. Issues include file names, relative links, directory names, default pages, server created content, image maps, other file types and embedded programming. With care, it is possible to create server based pages that can be copied directly to CD-ROM. In addition, Web pages on CD-ROM may reference Internet served pages to provide the best features of both methods.

    Callahan, John; Ramakrishnan, Sudhaka

    1996-01-01

    We briefly describe a system for forms-based, work-flow management that helps members of a software development team overcome geographical barriers to collaboration. Our system, called the Web Integrated Software Environment (WISE), is implemented as a World-Wide-Web service that allows for management and measurement of software development projects based on dynamic analysis of change activity in the workflow. WISE tracks issues in a software development process, provides informal communication between the users with different roles, supports to-do lists, and helps in software process improvement. WISE minimizes the time devoted to metrics collection and analysis by providing implicit delivery of messages between users based on the content of project documents. The use of a database in WISE is hidden from the users who view WISE as maintaining a personal 'to-do list' of tasks related to the many projects on which they may play different roles.

    Sun, Charles; Windrem, May; Givens, John J. (Technical Monitor)

    1998-01-01

    World Wide Web (W3) technologies such as the Hypertext Transfer Protocol (HTTP) and the Java object-oriented programming environment offer a powerful, yet relatively inexpensive, framework for distributed application software development. This paper describes the design of a real-time payload control and monitoring system that was developed with W3 technologies at NASA Ames Research Center. Based on Java Development Toolkit (JDK) 1.1, the system uses an event-driven "publish and subscribe" approach to inter-process communication and graphical user-interface construction. A C Language Integrated Production System (CLIPS) compatible inference engine provides the back-end intelligent data processing capability, while Oracle Relational Database Management System (RDBMS) provides the data management function. Preliminary evaluation shows acceptable performance for some classes of payloads, with Java's portability and multimedia support identified as the most significant benefit.

  2. Health information seeking and the World Wide Web: an uncertainty management perspective.

    Science.gov (United States)

    Rains, Stephen A

    2014-01-01

    Uncertainty management theory was applied in the present study to offer one theoretical explanation for how individuals use the World Wide Web to acquire health information and to help better understand the implications of the Web for information seeking. The diversity of information sources available on the Web and potential to exert some control over the depth and breadth of one's information-acquisition effort is argued to facilitate uncertainty management. A total of 538 respondents completed a questionnaire about their uncertainty related to cancer prevention and information-seeking behavior. Consistent with study predictions, use of the Web for information seeking interacted with respondents' desired level of uncertainty to predict their actual level of uncertainty about cancer prevention. The results offer evidence that respondents who used the Web to search for cancer information were better able than were respondents who did not seek information to achieve a level of uncertainty commensurate with the level of uncertainty they desired.

    1997-01-01

    Recent developments in Internet technologies are changing and enhancing how one processes and exchanges information. These developments include software and hardware in support of multimedia applications on the World Wide Web. In this paper the authors describe these technologies as they have applied them to remote monitoring and show how they will allow the International Atomic Energy Agency to efficiently review and analyze remote monitoring data for verification of material movements. The authors have developed demonstration software that illustrates several safeguards data systems using the resources of the Internet and Web to access and review data. This Web demo allows the user to directly observe sensor data, to analyze simulated safeguards data, and to view simulated on-line inventory data. Future activities include addressing the technical and security issues associated with using the Web to interface with existing and planned monitoring systems at nuclear facilities. Some of these issues are authentication, encryption, transmission of large quantities of data, and data compression

    1994-01-01

    Various human activities are, without a doubt, leading to a steady increase world-wide in the emissions of trace gases which affect the climate into the atmosphere. As a result, the global climate is also forced to change. The evidence from climate models regarding this is uncertain, however, both with respect to the quantitative aspect and the regional aspect, especially concerning climatic elements apart from temperature. It is therefore important to examine the data of climate history for anthropogenic climate signals. It is difficult, though, to distinguish between natural and anthropogenic climate effects. Despite these uncertainties, however, which result in many questions remaining open, estimations of risk and the principle of responsibility lead to immediate, international climate protection measures being demanded.

    Brown, C M

    1997-08-01

    The World Wide Web (WWW) is a burgeoning information resource that can be utilized for current awareness and assistance in manuscript preparation and submission. The ever changing and expanding nature of the WWW allows it to provide up to the minute information, but this inherent changeability often makes information access difficult. To assist nutrition scientists in locating useful information about nutritional science journals on the WWW, this article critically reviews and describes the WWW sites for seventeen highly ranked nutrition and dietetics journals. Included in each annotation are the site's title, web address or Universal Resource Locator (URL), journal ranking and site authorship. Also listed is whether or not the site makes available the guidelines for authors, tables of contents, abstracts, online ordering, as well as information about the editorial board. This critical survey illustrates that the information on the web, regardless of its authority, is not of equal quality.

    Transgenic crops among the most controversial "science and society" issues of recent years. Because of the complex techniques involved in creating these crops and the polarized debate over their risks and beliefs, a critical need has arisen for accessible and balanced information on this technology. World Wide Web sites offer several advantages for disseminating information on a fast-changing technical topic, including their global accessibility; and their ability to update information frequently, incorporate multimedia formats, and link to networks of other sites. An alliance between two complementary web sites at Colorado State University and the University of Nebraska-Lincoln takes advantage of the web environment to help fill the need for public information on crop genetic engineering. This article describes the objectives and features of each site. Viewership data and other feedback have shown these web sites to be effective means of reaching public audiences on a complex scientific topic.

    Fay, Jonathan; Roberts, Douglas A.

    2016-01-01

    After eight years of development by Microsoft Research, WorldWide Telescope (WWT) was made an open source project at the end of June 2015. WWT was motivated by the desire to put new surveys of objects, such as the Sloan Digital Sky Survey in the context of the night sky. The development of WWT under Microsoft started with the creation of a Windows desktop client that is widely used in various education, outreach and research projects. Using this, users can explore the data built into WWT as well as data that is loaded in. Beyond exploration, WWT can be used to create tours that present various datasets a narrative format.In the past two years, the team developed a collection of web controls, including an HTML5 web client, which contains much of the functionality of the Windows desktop client. The project under Microsoft has deep connections with several user communities such as education through the WWT Ambassadors program, http://wwtambassadors.org/ and with planetariums and museums such as the Adler Planetarium. WWT can also support research, including using WWT to visualize the Bones of the Milky Way and rich connections between WWT and the Astrophysical Data Systems (ADS, http://labs.adsabs.harvard.edu/adsabs/). One important new research connection is the use of WWT to create dynamic and potentially interactive supplements to journal articles, which have been created in 2015.Now WWT is an open source community lead project. The source code is available in GitHub (https://github.com/WorldWideTelescope). There is significant developer documentation on the website (http://worldwidetelescope.org/Developers/) and an extensive developer workshops (http://wwtworkshops.org/?tribe_events=wwt-developer-workshop) has taken place in the fall of 2015.Now that WWT is open source anyone who has the interest in the project can be a contributor. As important as helping out with coding, the project needs people interested in documentation, testing, training and other roles.

  9. Using the World Wide Web to Connect Research and Professional Practice: Towards Evidence-Based Practice

    Full Text Available In most professional (applied disciplines, research findings take a long time to filter into practice, if they ever do at all. The result of this is under-utilisation of research results and sub-optimal practices. There are a number of reasons for the lack of knowledge transfer. On the "demand side", people working in professional practice have little time available to keep up with the latest research in their field. In addition, the volume of research published each year means that the average practitioner would not have time to read all the research articles in their area of interest even if they devoted all their time to it. From the "supply side", academic research is primarily focused on the production rather than distribution of knowledge. While they have highly developed mechanisms for transferring knowledge among themselves, there is little investment in the distribution of research results be-yond research communities. The World Wide Web provides a potential solution to this problem, as it provides a global information infrastructure for connecting those who produce knowledge (researchers and those who need to apply this knowledge (practitioners. This paper describes two projects which use the World Wide Web to make research results directly available to support decision making in the workplace. The first is a successful knowledge management project in a health department which provides medical staff with on-line access to the latest medical research at the point of care. The second is a project currently in progress to implement a similar system to support decision making in IS practice. Finally, we draw some general lessons about how to improve transfers of knowledge from research and practice, which could be applied in any discipline.

  10. Global Deliberative Democracy and Climate Change: Insights from World Wide Views on Global Warming in Australia

    Directory of Open Access Journals (Sweden)

    Chris Riedy

    2011-12-01

    Full Text Available On 26 September 2009, approximately 4,000 citizens in 38 countries participated in World Wide Views on Global Warming (WWViews. WWViews was an ambitious first attempt to convene a deliberative mini-public at a global scale, giving people from around the world an opportunity to deliberate on international climate policy and to make recommendations to the decision-makers meeting at the United Nations Climate Change Conference in Copenhagen (COP-15 in December 2009. In this paper, we examine the role that deliberative mini-publics can play in facilitating the emergence of a global deliberative system for climate change response. We pursue this intent through a reflective evaluation of the Australian component of the World Wide Views on Global Warming project (WWViews. Our evaluation of WWViews is mixed. The Australian event was delivered with integrity and feedback from Australian participants was almost universally positive. Globally, WWViews demonstrated that it is feasible to convene a global mini-public to deliberate on issues of global relevance, such as climate change. On the other hand, the contribution of WWViews towards the emergence of a global deliberative system for climate change response was limited and it achieved little influence on global climate change policy. We identify lessons for future global mini-publics, including the need to prioritise the quality of deliberation and provide flexibility to respond to cultural and political contexts in different parts of the world. Future global mini-publics may be more influential if they seek to represent discourse diversity in addition to demographic profiles, use designs that maximise the potential for transmission from public to empowered space, run over longer time periods to build momentum for change and experiment with ways of bringing global citizens together in a single process instead of discrete national events.

  11. Women, pharmacy and the World Wide Web: could they be the answer to the obesity epidemic?

    Science.gov (United States)

    Fakih, Souhiela; Hussainy, Safeera; Marriott, Jennifer

    2014-04-01

    The objective of this article is to explore how giving women access to evidence-based information in weight management through pharmacies, and by utilising the World Wide Web, is a much needed step towards dealing with the obesity crisis. Women's needs should be considered when developing evidence-based information on weight. Excess weight places them at high risk of diabetes and cardiovascular disease, infertility and complications following pregnancy and giving birth. Women are also an important population group because they influence decision-making around meal choices for their families and are the biggest consumers of weight-loss products, many of which can be purchased in pharmacies. Pharmacies are readily accessible primary healthcare locations and given the pharmacist's expertise in being able to recognise underlying causes of obesity (e.g. medications, certain disease states), pharmacies are an ideal location to provide women with evidence-based information on all facets of weight management. Considering the exponential rise in the use of the World Wide Web, this information could be delivered as an online educational resource supported by other flexible formats. The time has come for the development of an online, evidence-based educational resource on weight management, which is combined with other flexible formats and targeted at women in general and according to different phases of their lives (pregnancy, post-partum, menopause). By empowering women with this knowledge it will allow them and their families to take better control of their health and wellbeing, and it may just be the much needed answer to complement already existing resources to help curb the obesity epidemic. © 2013 Royal Pharmaceutical Society.

    2014-01-01

    Findings from diverse subfields of vision research suggest a potential link between high-level aspects of face perception and concentric form-from-structure perception. To explore this relationship, typical adults performed two adaptation experiments and two masking experiments to test whether concentric, but not nonconcentric, Glass patterns (a type of form-from-structure stimulus) utilize a processing mechanism shared by face perception. For the adaptation experiments, subjects were presented with an adaptor for 5 or 20 s, prior to discriminating a target. In the masking experiments, subjects saw a mask, then a target, and then a second mask. Measures of discriminability and bias were derived and repeated measures analysis of variance tested for pattern-specific masking and adaptation effects. Results from Experiment 1 show no Glass pattern-specific effect of adaptation to faces; results from Experiment 2 show concentric Glass pattern masking, but not adaptation, may impair upright/inverted face discrimination; results from Experiment 3 show concentric and radial Glass pattern masking impaired subsequent upright/inverted face discrimination more than translational Glass pattern masking; and results from Experiment 4 show concentric and radial Glass pattern masking impaired subsequent face gender discrimination more than translational Glass pattern masking. Taken together, these findings demonstrate interactions between concentric form-from-structure and face processing, suggesting a possible common processing pathway. PMID:24563526

    Watson, Val; Chancellor, Marisa K. (Technical Monitor)

    1996-01-01

    Two new technologies, the FASTexpedition and Remote FAST, have been developed that provide remote, 3D (three dimensional), high resolution, dynamic, interactive viewing of scientific data. The FASTexpedition permits one to access scientific data from the World Wide Web, take guided expeditions through the data, and continue with self controlled expeditions through the data. Remote FAST permits collaborators at remote sites to simultaneously view an analysis of scientific data being controlled by one of the collaborators. Control can be transferred between sites. These technologies are now being used for remote collaboration in joint university, industry, and NASA projects. Also, NASA Ames Research Center has initiated a project to make scientific data and guided expeditions through the data available as FASTexpeditions on the World Wide Web for educational purposes. Previously, remote visualization of dynamic data was done using video format (transmitting pixel information) such as video conferencing or MPEG (Motion Picture Expert Group) movies on the Internet. The concept for this new technology is to send the raw data (e.g., grids, vectors, and scalars) along with viewing scripts over the Internet and have the pixels generated by a visualization tool running on the viewers local workstation. The visualization tool that is currently used is FAST (Flow Analysis Software Toolkit). The advantages of this new technology over using video format are: (1) The visual is much higher in resolution (1280x1024 pixels with 24 bits of color) than typical video format transmitted over the network. (2) The form of the visualization can be controlled interactively (because the viewer is interactively controlling the visualization tool running on his workstation). (3) A rich variety of guided expeditions through the data can be included easily. (4) A capability is provided for other sites to see a visual analysis of one site as the analysis is interactively performed. Control of

    1997-01-01

    Purpose/Objective: The Internet offers a novel venue for providing educational material to radiation oncologists. This exhibit demonstrates its utility for providing the complete content of two past ASTRO refresher courses. Materials and Methods: The audio recording, handout and slides from the 1995 ASTRO refresher course entitled 'Radiation Therapy for Pediatric Brain Tumors; Standards of Care, Current Clinical Trials and New Directions' and the 1996 ASTRO refresher course entitled 'Internet-based communications in Radiation Oncology' were digitized and placed on an Internet World-Wide-Web site. The Web address was posted on the refresher course handout and in the meeting book ('http://goldwein 1.xrt.upenn.edu/brain95.html' and 'http://goldwein 1.xrt.upenn.edu/astro96/'). The computer distributing this material is an Intel-based 486 DEC50 personal computer with a 50 Mhz processor running Windows NT 3.51 workstation. Software utilized to distribute the material is in the public domain and includes EWMAC's 'httpd', and Progressive Network's 'RealAudio Server' and 'Encoder'. The University's dedicated Internet connection is used to 'serve' this material. Results: The two approximately 100 minute lectures have been encoded into several 'RealAudio' files totaling 10 Megabytes in size. These files are accessible with moderate to excellent quality and speed utilizing as little as a 14.4k modem connection to the Internet. Use of 'streaming' technology provides a means for playing the audio files over the Internet after downloading only a small portion of the files. The time required to digitize the material has been approximately 40 hours, with most time related to digitizing slides from a Powerpoint presentation. Not all slides have been digitized as of this time. To date, approximately 400 accesses to this resource have been logged on the system. Seven electronic comment forms for the second course have all rated it as 'superior'. Pitfalls include the difficulty

    Compact optical discs (CDs and the World Wide Web (the Web are two mechanisms that contemporary libraries extensively use for digitized information storage, dissemination, and retrieval. The Web features an unparalleled global accessibility free from many previously known temporal and spatial restrictions. Its real-time update capability is impossible for CDs. Web-based information delivery can reduce the cost in hardware and software ownership and management of a local library, and provide one-to-one zcustomization to better serve library's clients. The current limitations of the Web include inadequate speed in data transmission, particularly for multimedia applications, and its insufficient reliability, search capabilities, and security. In comparison, speed, quality, portability, and reliability are the current advantages of CDs over the Web. These features, together with the trend in the PC industry and market, suggest that CDs will exist and continue to develop. CD/Web hybrids can combine the best of both developing mechanisms and offer optimal results. Through a comparison of CDs and the Web, it is argued that the functionality and unique features of a technology determine its future.

  18. Securing the anonymity of content providers in the World Wide Web

    1999-04-01

    Nowadays the World Wide Web (WWW) is an established service used by people all over the world. Most of them do not recognize the fact that they reveal plenty of information about themselves or their affiliation and computer equipment to the providers of web pages they connect to. As a result, a lot of services offer users to access web pages unrecognized or without risk of being backtracked, respectively. This kind of anonymity is called user or client anonymity. But on the other hand, an equivalent protection for content providers does not exist, although this feature is desirable for many situations in which the identity of a publisher or content provider shall be hidden. We call this property server anonymity. We will introduce the first system with the primary target to offer anonymity for providers of information in the WWW. Beside this property, it provides also client anonymity. Based on David Chaum's idea of mixes and in relation to the context of the WWW, we explain the term 'server anonymity' motivating the system JANUS which offers both client and server anonymity.

    2016-02-01

    This paper objectively evaluates current information available to the general public related to glue ear on the World Wide Web. The term 'glue ear' was typed into the 3 most frequently used internet search engines - Google, Bing and Yahoo - and the first 20 links were analysed. The first 400 words of each page were used to calculate the Flesch-Kincaid readability score. Each website was subsequently graded using the Discern instrument, which gauges quality and content of literature. The websites Webmd.boots.com, Bupa.co.uk and Patient.co.uk received the highest overall scores. These reflected top scores in either readability or Discern instrument assessment, but not both. Readability and Discern scores increased with the presence of a marketing or advertising incentive. The Patient.co.uk website had the highest Discern score and third highest readability score. There is huge variation in the quality of information available to patients on the internet. Some websites may be accessible to a wide range of reading ages but have poor quality content, and vice versa. Clinicians should be aware of indicators of quality, and use validated instruments to assess and recommend literature.

    2015-01-01

    A world-wide internet survey was conducted to test central assumptions of a recent theory of cultural transmission in minorities proposed by the authors. 844 1st to 2nd generation immigrants from a wide variety of countries recruited on a microjob platform completed a questionnaire designed to test eight hypotheses derived from the theory. Support was obtained for all hypotheses. In particular, evidence was obtained for the continued presence, in the immigrants, of the culture-transmission motive postulated by the theory: the desire to maintain the culture of origin and transmit it to the next generation. Support was also obtained for the hypothesized anchoring of the culture-transmission motive in more basic motives fulfilled by cultural groups, the relative intra- and intergenerational stability of the culture-transmission motive, and its motivating effects for action tendencies and desires that support cultural transmission under the difficult conditions of migration. Furthermore, the findings suggest that the assumption that people have a culture-transmission motive belongs to the folk psychology of sociocultural groups, and that immigrants regard the fulfillment of this desire as a moral right.

    1997-01-01

    Since 1963 Transnucleaire has safely performed a large number of national and international transports of radioactive material. Transnucleaire has also designed and supplied suitable packagings for all types of nuclear fuel cycle radioactive material from front-end and back-end products and for power or for research reactors. Transportation of the nuclear fuel material for power reactors is made on a regular and industrial basis. The transportation of material for the research reactor fuel cycle is quite different due to the small quantities involved, the categorisation of material and the numerous places of delivery world-wide. Adapted solutions exist, which require a reactive organisation dealing with all the transportation issues for LEU and HEU products as metal, oxide, fresh fuel elements, spent fuel elements including supply of necessary transport packaging and equipment. This presentation will: - explain the choices made by Transnucleaire and its associates to provide and optimise the corresponding services, - demonstrate the capability to achieve, through reliable partnership, transport operations involving new routes, specific equipment and new political constraints while respecting sophisticated safety and security regulations.

    In this paper, we present the design architecture and the implementation status of WebPresent - a world wide web based tele-presentation tool. This tool allows a physician to use a conference server workstation and make a presentation of patient cases to a geographically distributed audience. The audience consists of other physicians collaborating on patients' health care management and physicians participating in continuing medical education. These physicians are at several locations with networks of different bandwidth and capabilities connecting them. Audiences also receive the patient case information on different computers ranging form high-end display workstations to laptops with low-resolution displays. WebPresent is a scalable networked multimedia tool which supports the presentation of hypertext, images, audio, video, and a white-board to remote physicians with hospital Intranet access. WebPresent allows the audience to receive customized information. The data received can differ in resolution and bandwidth, depending on the availability of resources such as display resolution and network bandwidth.

    Literacy is a national and international problem. Studies have shown the readability of adult and pediatric patient education materials to be too high for average adults. Materials should be written at the 8th-grade level or lower. To determine the general readability of pediatric patient education materials designed for adults on the World Wide Web (WWW). GeneralPediatrics.com (http://www.generalpediatrics.com) is a digital library serving the medical information needs of pediatric health care providers, patients, and families. Documents from 100 different authoritative Web sites designed for laypersons were evaluated using a built-in computer software readability formula (Flesch Reading Ease and Flesch-Kincaid reading levels) and hand calculation methods (Fry Formula and SMOG methods). Analysis of variance and paired t tests determined significance. Eighty-nine documents constituted the final sample; they covered a wide spectrum of pediatric topics. The overall Flesch Reading Ease score was 57.0. The overall mean Fry Formula was 12.0 (12th grade, 0 months of schooling) and SMOG was 12.2. The overall Flesch-Kincaid grade level was significantly lower (Peducation materials on the WWW are not written at an appropriate reading level for the average adult. We propose that a practical reading level and how it was determined be included on all patient education materials on the WWW for general guidance in material selection. We discuss suggestions for improved readability of patient education materials.

    In response to a 1995 NASA SPDS announcement of support for preservation and distribution of important data sets online, the Geophysical Institute, University of Alaska Fairbanks, Alaska, proposed to provide World Wide Web access to the Poker Flat Auroral All-sky Camera images in real time. The Poker auroral all-sky camera is located in the Davis Science Operation Center at Poker Flat Rocket Range about 30 miles north-east of Fairbanks, Alaska, and is connected, through a microwave link, with the Geophysical Institute where we maintain the data base linked to the Web. To protect the low light-level all-sky TV camera from damage due to excessive light, we only operate during the winter season when the moon is down. The camera and data acquisition is now fully computer controlled. Digital images are transmitted each minute to the Web linked data base where the data are available in a number of different presentations: (1) Individual JPEG compressed images (1 minute resolution); (2) Time lapse MPEG movie of the stored images; and (3) A meridional plot of the entire night activity.

    A principal tenant of the scientific method is that experiments must be repeatable and relies on ceteris paribus (i.e., all other things being equal). As a scientific community, involved in data sciences, we must investigate ways to establish an environment where experiments can be repeated. We can no longer allude to where the data comes from, we must add rigor to the data collection and management process from which our analysis is conducted. This paper describes a computing environment to support repeatable scientific big data experimentation of world-wide scientific literature, and recommends a system that is housed at the Oak Ridge National Laboratory in order to provide value to investigators from government agencies, academic institutions, and industry entities. The described computing environment also adheres to the recently instituted digital data management plan mandated by multiple US government agencies, which involves all stages of the digital data life cycle including capture, analysis, sharing, and preservation. It particularly focuses on the sharing and preservation of digital research data. The details of this computing environment are explained within the context of cloud services by the three layer classification of Software as a Service , Platform as a Service , and Infrastructure as a Service .

    1994-09-01

    The Department of Energy - Office of Special Projects and Argonne National Laboratory (ANL), along with the Department of Energy - office of Scientific and Technical Information have previously designed and implemented the Environment, Safety and Health Facility Profile Information Management System (FPIMS) to facilitate greater efficiency in searching, analyzing and disseminating information found within environment, safety and health oversight documents. This information retrieval based system serves as a central repository for full-text electronic oversight documents, as well as a management planning and decision making tool that can assist in trend and root cause analyses. Continuous improvement of environment, safety and health programs are currently aided through this personal computer-based system by providing a means for the open communication of lessons learned across the department. Overall benefits have included reductions in costs and improvements in past information management capabilities. Access to the FPIMS has been possible historically through a headquarters-based local area network equipped with modems. Continued demand for greater accessibility of the system by remote DOE field offices and sites, in conjunction with the Secretary of Energy` s call for greater public accessibility to Department of Energy (DOE) information resources, has been the impetus to expand access through the use of Internet technologies. Therefore, the following paper will discuss reasons for migrating the FPIMS system into the World Wide Web (Web), various lessons learned from the FPIMS migration effort, as well as future plans for enhancing the Web-based FPIMS.

    1999-01-01

    The International Nuclear Event Scale (INES) is a means designed for providing prompt, clear and consistent information related to nuclear events, that occurred at nuclear facilities, and facilitating communication between the nuclear community, the media and the public. The INES is jointly operated by the IAEA and the OECD-NEA. Nuclear events reported are rated by the Scale', a consistent safety significance indicator. The scale runs from level 0, for events with no safety significance, to level 7 for a major accident with widespread health and environmental effects. The Japan Atomic Energy Research Institute (JAERI) has been promptly translating the INES reports into Japanese and developing a world-wide-web database for the Japanese translation, aiming at more efficient utilization of the INES information inside Japan. The present paper briefly introduces the definitions of INES rating levels and the scope of the Scale, and describes the outlines of the database (the information stored in the database, its functions and how to use it). As well, technical use of the INES reports and the availability/ effectiveness of the database are discussed. (author)

    To determine the validity of the information on the World Wide Web concerning veterinary anesthesia in dogs and to determine the methods dog owners use to obtain that information. Web-based search and client survey. 73 Web sites and 92 clients. Web sites were scored on a 5-point scale for completeness and accuracy of information about veterinary anesthesia by 3 board-certified anesthesiologists. A search for anesthetic information regarding 49 specific breeds of dogs was also performed. A survey was distributed to the clients who visited the University of Georgia Veterinary Teaching Hospital during a 4-month period to solicit data about sources used by clients to obtain veterinary medical information and the manner in which information obtained from Web sites was used. The general search identified 73 Web sites that included information on veterinary anesthesia; these sites received a mean score of 3.4 for accuracy and 2.5 for completeness. Of 178 Web sites identified through the breed-specific search, 57 (32%) indicated that a particular breed was sensitive to anesthesia. Of 83 usable, completed surveys, 72 (87%) indicated the client used the Web for veterinary medical information. Fifteen clients (18%) indicated they believed their animal was sensitive to anesthesia because of its breed. Information available on the internet regarding anesthesia in dogs is generally not complete and may be misleading with respect to risks to specific breeds. Consequently, veterinarians should appropriately educate clients regarding anesthetic risk to their particular dog.

    2009-01-01

    In my last Internet-related article, I speculated that social networking would be the coming wave in the effort to share knowledge among experts in various disciplines. At the time I did not know that a palliative care site on the World Wide Web (WWW), palliativedrugs.com, already provided the infrastructure for sharing expert knowledge in the field. The Web site is an excellent traditional formulary but it is primarily devoted to "unlicensed" ("off-label") use of medications in palliative care, something we in the specialty often do with little to support our interventions except shared knowledge and experience. There is nothing fancy about this Web site. In a good way, its format is a throwback to Web sites of the 1990s. In only the loosest sense can one describe it as "multimedia." Yet, it provides the perfect forum for expert knowledge and is a "must see" resource. Its existing content is voluminous and reliable, filtered and reviewed by renowned clinicians and educators in the field. Although its origin and structure were not specifically designed for social or professional networking, the Web site's format makes it a natural way for practitioners around the world to contribute to an ever-growing body of expertise in palliative care.

    In order for humans and electronics to fully and safely operate in the space environment, codes like HZETRN (High Charge and Energy Transport) must be included in any designer's toolbox for design evaluation with respect to radiation damage. Currently, spacecraft designers do not have easy access to accurate radiation codes like HZETRN to evaluate their design for radiation effects on humans and electronics. Today, the World Wide Web is sophisticated enough to support the entire HZETRN code and all of the associated pre and post processing tools. This package is called SIREST (Space Ionizing Radiation Effects and Shielding Tools). There are many advantages to SIREST. The most important advantage is the instant update capability of the web. Another major advantage is the modularity that the web imposes on the code. Right now, the major disadvantage of SIREST will be its modularity inside the designer's system. This mostly comes from the fact that a consistent interface between the designer and the computer system to evaluate the design is incomplete. This, however, is to be solved in the Intelligent Synthesis Environment (ISE) program currently being funded by NASA.

    Satellite data summary images and analysis plots from the Tropical Ocean Global Atmosphere Coupled Ocean-Atmosphere Response Experiment (TOGA COARE), which were initially prepared in the field at the Honiara Operations Center, are now available on the Internet via World Wide Web browsers such as Mosaic. These satellite data summaries consist of products derived from the Japanese Geosynchronous Meteorological Satellite IR data: a time-size series of the distribution of contiguous cold cloudiness areas, weekly percent high cloudiness (PHC) maps, and a five-month time-longitudinal diagram illustrating the zonal motion of large areas of cold cloudiness. The weekly PHC maps are overlaid with weekly mean 850-hPa wind calculated from the European Centre for Medium-Range Weather Forecasts (ECMWF) global analysis field and can be viewed as an animation loop. These satellite summaries provide an overview of spatial and temporal variabilities of the cloud population and a large-scale context for studies concerning specific processes of various components of TOGA COARE.

    Full Text Available In the past decade, the use of the World Wide Web (WWW as a tool for job-seeking and recruitment has increased globally, changing the dynamics for job-seekers and recruitment organisations. The purpose of this study was to gain greater insight into the factors that influence the adoption of the Internet (WWW for job-seeking within a South African context. The impact of the Internet (WWW and newspaper-reading habits on the adoption process was of specific interest. Data was gathered by survey through telephonic interviews with 228 job seekers applying for information technology (IT work in Cape Town, South Africa. The findings show that the income of a job-seeker influences the favourability of internet facilitating conditions they encounter. Facilitating conditions in turn influence Internet (WWW usage habits. Such habits influence performance expectancy, effort expectancy and intentions to use the Internet (WWW for job-seeking. The actual extent of Internet (WWW usage for job-seeking is positively influenced by these usage intentions and negatively influenced by newspaper-reading habits. These and other findings are discussed and implications drawn.

    The `conjunction fallacy' has been extensively debated by scholars in cognitive science and, in recent times, the discussion has been enriched by the proposal of modeling the fallacy using the quantum formalism. Two major quantum approaches have been put forward: the first assumes that respondents use a two-step sequential reasoning and that the fallacy results from the presence of `question order effects'; the second assumes that respondents evaluate the cognitive situation as a whole and that the fallacy results from the `emergence of new meanings', as an `effect of overextension' in the conceptual conjunction. Thus, the question arises as to determine whether and to what extent conjunction fallacies would result from `order effects' or, instead, from `emergence effects'. To help clarify this situation, we propose to use the World Wide Web as an `information space' that can be interrogated both in a sequential and non-sequential way, to test these two quantum approaches. We find that `emergence effects', and not `order effects', should be considered the main cognitive mechanism producing the observed conjunction fallacies.

  15. World-wide risk assessment of the transportation of radioactive materials

    The aim of the project reported in this paper is to develop the means and methods for a risk analysis of the transportation of radioactive materials throughout the world. The project was initiated by the Standing Advisory Group on the Safe Transport of Radioactive Materials (SAGSTRAM) of the IAEA. In 1979 the Swedish Nuclear Power Inspectorate and the IAEA signed an agreement on the development of a model for calculation of the transport risk. Member States of the IAEA are invited to use the model for a risk assessment of the transportation of radioactive materials in their own country. These assessments will be collected and analyzed and a world-wide risk assessment performed. The IAEA has the overall responsibility for the project and administers it. Sweden manages the project and has performed the applied research with the assistance of research support groups which have supplied data and analyses and performed some other parts of the project. An Oversight Committee with participants from eight Member States has reviewed the progress and has given valuable recommendations. It was important that the model had the sophistication and flexibility required for its use by all Member States but still was easy to handle. The risk calculations are performed by the computer code INTERTRAN which is based on the American computer code RADTRAN II developed by Sandia National Laboratories, Albuquerque, NM. The methodology of the RADTRAN II as well as data and format of the input and output was changed to make the code more internationally oriented. 2 references

    The Boyd E. Christenberry Planetarium at Samford University (Birmingham, AL) offers family friendly, live, and interactive planetarium presentations that educate the public on topics from astronomy basics to current cutting edge astronomical discoveries. With limited funding, it is not possible to provide state of the art planetarium hardware for these community audiences. In a society in which many people, even young children, have access to high resolution smart phones and highly realistic video games, it is important to leverage cutting-edge technology to intrigue young and old minds alike. We use an Oculus Rift virtual reality headset running AAS WorldWide Telescope software to visualize 3D data in a fully immersive environment. We create interactive experiences and videos to highlight astronomical concepts and also to communicate the beauty of our universe. The ease of portability enables us to set up at Virtual Reality (VR) experience at various events, festivals, and even in classrooms to provide a community outreach that a fixed planetarium cannot. This VR experience adds the “wow” factor that encourages children and adults to engage in our various planetarium events to learn more about astronomy and continue to explore the final frontier of space. These VR experiences encourages our college students to participate in our astronomy education resulting in increased interest in STEM fields, particularly physics and math.

    New, visually rich, astronomical software environments coupled with large web-accessible data sets hold the promise of new and exciting ways to teach, collaborate, and explore the universe. These freeware tools provide contextual views of astronomical objects, real time access to multi-wavelength sky surveys, and, most importantly, the ability to incorporate new data and to produce user created content. This interactive panel examined the capabilities of Google Sky and WorldWide Telescope, and explored case studies of how these tools have been used to create compelling and participatory educational experiences in both formal (i.e., K-12 and undergraduate non-science majors classrooms), and informal (e.g., museum) settings. The overall goal of this session was to stimulate a discussion about future uses of these technologies. Substantial time was allotted for participants to create conceptual designs of learning experiences for use at their home institutions, with feedback provided by the panel members. Activities included technical discussions (e.g., mechanisms for incorporating new data and dissemination tools), exercises in narrative preparation, and a brainstorming session to identify potential future uses of these technologies.

    2014-06-01

    Full Text Available A selective ensemble hybrid modeling prediction method based on wavelet transformation is proposed to improve the fitting and generalization capability of the existing prediction models of the coal face gas concentration, which has a strong stochastic volatility. Mallat algorithm was employed for the multi-scale decomposition and single-scale reconstruction of the gas concentration time series. Then, it predicted every subsequence by sparsely weighted multi unstable ELM(extreme learning machine predictor within method SERELM(sparse ensemble regressors of ELM. At last, it superimposed the predicted values of these models to obtain the predicted values of the original sequence. The proposed method takes advantage of characteristics of multi scale analysis of wavelet transformation, accuracy and fast characteristics of ELM prediction and the generalization ability of L1 regularized selective ensemble learning method. The results show that the forecast accuracy has large increase by using the proposed method. The average relative error is 0.65%, the maximum relative error is 4.16% and the probability of relative error less than 1% reaches 0.785.

  1. On the necessity of making geoethics a central concern in eduethics world-wide

    Our planet is in dire need of ethical behaviour by all its citizens. However, recent research has highlighted the increasingly dangerous impact of human activity on life systems of the planet. CO2 emissions continue to rise (400+ppm, end 2016), methane emissions are accelerating. The Arctic is about 28°C above the normal average. Average global temperature is reaching 1° above normal. Air, water and ground pollution levels are reaching devastating levels. Resource depletion is accelerating. Yet most governments still beat the drums of growth, while hypocritically humming the tune of sustainability. Humans are overshooting the carrying capacity of the planet; as attested by top scientists and organizations. Earth overshoot day in 2016 was 8 August; we need 5½ earths to live like Australians. Of course, efforts are being made globally and locally to combat impending disaster and to encourage more respectful behaviour towards the planet and its life. Individuals include scientists, writers, film makers, journalists. World-wide organizations include Climate Literacy and Energy Awareness Network (CLEAN), the Climate Change Education Partnership Alliance, the International Geoscience Education Organisation (IGEO), and the United Nations Environment Programme (UNEP). A key organization is the International Association for Promoting Geoethics (IAPG) because it focuses firmly and explicitly on the key issue of ethics, which few others appear to do. One might argue that the general lack of major progress in environmental care is rooted to a large degree in the world-wide lack of strong adherence to geoethical principles. Learning to behave ethically needs far more than knowledge about energy imbalance, pollution, acidity, ice melt, etc. It needs people to learn, and grow up learning, about what is right and wrong in regard to each aspect of our personal earth citizen lives. That needs nothing short of a revolution in educational practice for all schools across the globe

    Research engineers at the National Library of Medicine are building a prototype system for the delivery of multimedia biomedical information on the World Wide Web. This paper discuses the architecture and design considerations for the system, which will be used initially to make images and text from the third National Health and Nutrition Examination Survey (NHANES) publicly available. We categorized our analysis as follows: (1) fundamental software tools: we analyzed trade-offs among use of conventional HTML/CGI, X Window Broadway, and Java; (2) image delivery: we examined the use of unconventional TCP transmission methods; (3) database manager and database design: we discuss the capabilities and planned use of the Informix object-relational database manager and the planned schema for the HNANES database; (4) storage requirements for our Sun server; (5) user interface considerations; (6) the compatibility of the system with other standard research and analysis tools; (7) image display: we discuss considerations for consistent image display for end users. Finally, we discuss the scalability of the system in terms of incorporating larger or more databases of similar data, and the extendibility of the system for supporting content-based retrieval of biomedical images. The system prototype is called the Web-based Medical Information Retrieval System. An early version was built as a Java applet and tested on Unix, PC, and Macintosh platforms. This prototype used the MiniSQL database manager to do text queries on a small database of records of participants in the second NHANES survey. The full records and associated x-ray images were retrievable and displayable on a standard Web browser. A second version has now been built, also a Java applet, using the MySQL database manager.

  3. Towards a global service registry for the world-wide LHC computing grid

    2014-01-01

    The World-Wide LHC Computing Grid encompasses a set of heterogeneous information systems; from central portals such as the Open Science Grid's Information Management System and the Grid Operations Centre Database, to the WLCG information system, where the information sources are the Grid services themselves. Providing a consistent view of the information, which involves synchronising all these informations systems, is a challenging activity that has lead the LHC virtual organisations to create their own configuration databases. This experience, whereby each virtual organisation's configuration database interfaces with multiple information systems, has resulted in the duplication of effort, especially relating to the use of manual checks for the handling of inconsistencies. The Global Service Registry aims to address this issue by providing a centralised service that aggregates information from multiple information systems. It shows both information on registered resources (i.e. what should be there) and available resources (i.e. what is there). The main purpose is to simplify the synchronisation of the virtual organisation's own configuration databases, which are used for job submission and data management, through the provision of a single interface for obtaining all the information. By centralising the information, automated consistency and validation checks can be performed to improve the overall quality of information provided. Although internally the GLUE 2.0 information model is used for the purpose of integration, the Global Service Registry in not dependent on any particular information model for ingestion or dissemination. The intention is to allow the virtual organisation's configuration databases to be decoupled from the underlying information systems in a transparent way and hence simplify any possible future migration due to the evolution of those systems. This paper presents the Global Service Registry architecture, its advantages

    The great interest for utilization of nuclear materials to produce energy in the middle of last century needed special investigations using first class research facilities. Common problems in the area of nuclear fuel development motivated the establishment of joint research efforts. The OECD Halden Reactor Project (HRP) is a good example of such a cooperative research effort, which has been performing for more than 50 years. During that time, the Halden Reactor evolved from a prototype heavy water reactor envisaged as a power source for different applications to a research reactor that is able to simulate in-core conditions of modern commercial power reactors. The adaptability of the Halden Reactor enables the HRP to be an important international test facility for nuclear fuels and materials development. The long-term international cooperation is based on the flexible HRP organizational structure which also provides the continued success. [1,2] This paper gives a brief history of the Halden Reactor Project and its contribution to world-wide nuclear energy development. Recent expansion of the Project to the East and Asian countries may also assist and stimulate the development of a nuclear industry within these countries. The achievements of the HRP rely on the versatility of the research carried out in the reactor with reliable testing techniques and in-pile instrumentation. Diversification of scientific activity in the areas of development of alternative energy resources and man-machine technology also provide the HRP with a stable position as one of the leaders in the world scientific community. All of these aspects are described in this paper together with current experimental works, including the investigation of ULBA (Kazakhstan) production fuel in comparison with other world fuel suppliers, as well as other future and prospective plans of the Project.(Author)

    Mandatory preparticipation examinations (PPE) are labor intensive, offer little routine health maintenance and are poor predictors of future injury or illness. Our objective was to develop a new PPE for the Stanford University varsity athletes that improved both quality of primary and preventive care and physician time efficiency. This PPE is based on the annual submission, by each athlete, of a comprehensive medical history questionnaire that is then summarized in a two-page report for the examining physician. The questionnaire was developed through a search of MEDLINE from 1966 to 1997, review of PPE from 11 other institutions, and discussion with two experts from each of seven main content areas: medical and musculoskeletal history, eating, menstrual and sleep disorders, stress and health risk behaviors. Content validity was assessed by 10 sports medicine physicians and four epidemiologists. It was then programmed for the World Wide Web (http:// www.stanford.edu/dept/sportsmed/). The questionnaire demonstrated a 97 +/- 2% sensitivity in detecting positive responses requiring physician attention. Sixteen physicians administered the 1997/98 PPE; using the summary reports, 15 found improvement in their ability to provide overall medical care including health issues beyond clearance; 13 noted a decrease in time needed for each athlete exam. Over 90% of athletes who used the web site found it "easy" or "moderately easy" to access and complete. Initial assessment of this new PPE format shows good athlete compliance, improved exam efficiency and a strong increase in subjective physician satisfaction with the quality of screening and medical care provided. The data indicate a need for improvement of routine health maintenance in this population. The database offers opportunities to study trends, risk factors, and results of interventions.

    Both global area coverage (GAC) and high-resolution picture transmission (HRTP) data from the Advanced Very High Resolution Radiometer (AVHRR) are made available to laternet users through an online data access system. Older GOES-7 data am also available. Created as a "testbed" data system for NASA's future Earth Observing System Data and Information System (EOSDIS), this testbed provides an opportunity to test both the technical requirements of an onune'd;ta system and the different ways in which the -general user, community would employ such a system. Initiated in December 1991, the basic data system experienced five major evolutionary changes In response to user requests and requirements. Features added with these changes were the addition of online browse, user subsetting, dynamic image Processing/navigation, a stand-alone data storage system, and movement,from an X-windows graphical user Interface (GUI) to a World Wide Web (WWW) interface. Over Its lifetime, the system has had as many as 2500 registered users. The system on the WWW has had over 2500 hits since October 1995. Many of these hits are by casual users that only take the GIF images directly from the interface screens and do not specifically order digital data. Still, there b a consistent stream of users ordering the navigated image data and related products (maps and so forth). We have recently added a real-time, seven- day, northwestern United States normalized difference vegetation index (NDVI) composite that has generated considerable Interest.

    Traditionally, surgical education has been confined to operating and lecture theaters. Access to the World Wide Web and services, such as YouTube and iTunes has expanded enormously. Each week throughout Ireland, nonconsultant hospital doctors work hard to create presentations for surgical teaching. Once presented, these valuable presentations are often never used again. We aimed to compile surgical presentations online and establish a new online surgical education tool. We also sought to measure the effect of this educational tool on surgical presentation quality. Surgical presentations from Cork University Hospital and Beaumont Hospital presented between January 2010 and April 2011 were uploaded to http://www.pilgrimshospital.com/presentations. A YouTube channel and iTunes application were created. Web site hits were monitored. Quality of presentations was assessed by 4 independent senior surgical judges using a validated PowerPoint assessment form. Judges were randomly given 6 presentations; 3 presentations were pre-web site setup and 3 were post-web site setup. Once uploading commenced, presenters were informed. A total of 89 presentations have been uploaded to date. This includes 55 cases, 17 journal club, and 17 short bullet presentations. This has been associated with 46,037 web site page views. Establishment of the web site was associated with a significant improvement in the quality of presentations. Mean scores for pre- and post-web site group were 6.2 vs 7.7 out of 9 respectively, p = 0.037. This novel educational tool provides a unique method to enable surgical education become more accessible to trainees, while also improving the overall quality of surgical teaching PowerPoint presentations.

    To objectively assess the quality of information available on the World Wide Web on cardiac resynchronization therapy (CRT). Patients frequently search the internet regarding their healthcare issues. It has been shown that patients seeking information can help or hinder their healthcare outcomes depending on the quality of information consulted. On the internet, this information can be produced and published by anyone, resulting in the risk of patients accessing inaccurate and misleading information. The search term "Cardiac Resynchronisation Therapy" was entered into the three most popular search engines and the first 50 pages on each were pooled and analyzed, after excluding websites inappropriate for objective review. The "LIDA" instrument (a validated tool for assessing quality of healthcare information websites) was to generate scores on Accessibility, Reliability, and Usability. Readability was assessed using the Flesch Reading Ease Score (FRES). Of the 150 web-links, 41 sites met the eligibility criteria. The sites were assessed using the LIDA instrument and the FRES. A mean total LIDA score for all the websites assessed was 123.5 of a possible 165 (74.8%). The average Accessibility of the sites assessed was 50.1 of 60 (84.3%), on Usability 41.4 of 54 (76.6%), on Reliability 31.5 of 51 (61.7%), and 41.8 on FRES. There was a significant variability among sites and interestingly, there was no correlation between the sites' search engine ranking and their scores. This study has illustrated the variable quality of online material on the topic of CRT. Furthermore, there was also no apparent correlation between highly ranked, popular websites and their quality. Healthcare professionals should be encouraged to guide their patients toward the online material that contains reliable information. © 2016 Wiley Periodicals, Inc.

    Freshwater "scarcity" has been identified as being a major problem world-wide, but it is surprisingly hard to assess if water is truly scarce at a global or even regional scale. Most empirical water research remains location specific. Characterizing water problems, transferring lessons across regions, to develop a synthesized global view of water issues remains a challenge. In this study we attempt a systematic understanding of water problems across regions. We compared case studies of basins across different regions of the world using configurational frequency analysis. Because water crises are multi-symptom and multi-causal, a major challenge was to categorize water problems so as to make comparisons across cases meaningful. In this study, we focused strictly on water unsustainability, viz. the inability to sustain current levels of the anthropogenic (drinking water, food, power, livelihood) and natural (aquatic species, wetlands) into the future. For each case, the causes of three outcome variables, groundwater declines, surface water declines and aquatic ecosystem declines, were classified and coded. We conducted a meta-analysis in which clusters of peer-reviewed papers by interdisciplinary teams were considered to ensure that the results were not biased towards factors privileged by any one discipline. Based on our final sample of 22 case study river basins, some clear patterns emerged. The meta-analysis suggests that water resources managers have long overemphasized the factors governing supply of water resources and while insufficient attention has been paid to the factors driving demand. Overall, uncontrolled increase in demand was twice as frequent as declines in availability due to climate change or decreased recharge. Moreover, groundwater and surface water declines showed distinct causal pathways. Uncontrolled increases in demand due to lack of credible enforcement were a key factor driving groundwater declines; while increased upstream abstractions

  12. Integrating video and animation with physics problem- solving exercises on the World Wide Web

    1998-10-01

    Problem solving is of paramount importance in teaching and learning physics. An important step in solving a problem is visualization. To help students visualize a problem, we included video clips with homework questions delivered via the World Wide Web. Although including video with physics problems has a positive effect with some problems, we found that this may not be the best way to integrate multimedia with physics problems since improving visualization is probably not as helpful as changing students' approach. To challenge how students solve problems and to help them develop a more expert-like approach, we developed a type of physics exercise called a multimedia-focused problem where students take data from an animation in order to solve a problem. Because numbers suggestive of a solution are not given in the text of the question, students have to consider the problem conceptually before analyzing it mathematically. As a result, we found that students had difficulty solving such problems compared to traditional textbook-like problems. Students' survey responses showed that students indeed had difficulty determining what was needed to solve a problem when it was not explicitly given to them in the text of the question. Analyzing think-aloud interviews where students verbalized their thoughts while solving problems, we found that multimedia-focused problems indeed required solid conceptual understanding in order for them to be solved correctly. As a result, we believe that when integrated with instruction, multimedia-focused problems can be a valuable tool in helping students develop better conceptual understanding and more expert-like problem solving skills by challenging novice beliefs and problem solving approaches. Multimedia-focused problems may also be useful for diagnosing conceptual understanding and problem skills.

  13. Educational Applications on the World Wide Web: An Example Using Amphion

    There is a great deal of excitement about using the internet and the World Wide Web in education. There are such exciting possibilities and there is a wealth and variety of material up on the web. There are however many problems, problems of access and resources, problems of quality -- for every excellent resource there are many poor ones, and there are insufficiently explored problems of teacher training and motivation. For example, Wiesenmayer and Meadows report on a study of 347 West Virginia science teachers. These teachers were enrolled in a week-long summer workshop to introduce them to the internet and its educational potential. The teachers were asked to review science sites as to overall quality and then about their usefulness in their own classrooms. The teachers were enthusiastic about the web, and gave two-thirds of the sites high ratings, and essentially all the rest average ratings. But alarmingly, over 80% of these sites were viewed as having no direct applicability in the teacher's own classroom. This summer I was assigned to work on the Amphion project in the Automated Software Engineering Group under the leadership of Michael Lowry. I wished to find educational applications of the Amphion system, which in its current implementation can be used to create fortran programs and animations using the SPICE libraries created by the NAIF group at JPL. I wished to find an application which provided real added educational value, which was in line with educational curriculum standards and which would serve a documented need of the educational community. The application selected was teaching about the causes of the seasons -- at the approximately the fourth, fifth, sixth grade level. This topic was chosen because it is in line with national curriculum standards. The fourth, fifth, sixth grade level was selected to coincide with the grade level served by the Ames Aerospace Encounter, which services 10,000 children a year on field trips. The hope is that

  14. Obtaining Streamflow Statistics for Massachusetts Streams on the World Wide Web

    2000-01-01

    A World Wide Web application has been developed to make it easy to obtain streamflow statistics for user-selected locations on Massachusetts streams. The Web application, named STREAMSTATS (available at http://water.usgs.gov/osw/streamstats/massachusetts.html ), can provide peak-flow frequency, low-flow frequency, and flow-duration statistics for most streams in Massachusetts. These statistics describe the magnitude (how much), frequency (how often), and duration (how long) of flow in a stream. The U.S. Geological Survey (USGS) has published streamflow statistics, such as the 100-year peak flow, the 7-day, 10-year low flow, and flow-duration statistics, for its data-collection stations in numerous reports. Federal, State, and local agencies need these statistics to plan and manage use of water resources and to regulate activities in and around streams. Engineering and environmental consulting firms, utilities, industry, and others use the statistics to design and operate water-supply systems, hydropower facilities, industrial facilities, wastewater treatment facilities, and roads, bridges, and other structures. Until now, streamflow statistics for data-collection stations have often been difficult to obtain because they are scattered among many reports, some of which are not readily available to the public. In addition, streamflow statistics are often needed for locations where no data are available. STREAMSTATS helps solve these problems. STREAMSTATS was developed jointly by the USGS and MassGIS, the State Geographic Information Systems (GIS) agency, in cooperation with the Massachusetts Departments of Environmental Management and Environmental Protection. The application consists of three major components: (1) a user interface that displays maps and allows users to select stream locations for which they want streamflow statistics (fig. 1), (2) a data base of previously published streamflow statistics and descriptive information for 725 USGS data

  15. Autonomous Satellite Command and Control through the World Wide Web: Phase 3

    1998-01-01

    NASA's New Millenium Program (NMP) has identified a variety of revolutionary technologies that will support orders of magnitude improvements in the capabilities of spacecraft missions. This program's Autonomy team has focused on science and engineering automation technologies. In doing so, it has established a clear development roadmap specifying the experiments and demonstrations required to mature these technologies. The primary developmental thrusts of this roadmap are in the areas of remote agents, PI/operator interface, planning/scheduling fault management, and smart execution architectures. Phases 1 and 2 of the ASSET Project (previously known as the WebSat project) have focused on establishing World Wide Web-based commanding and telemetry services as an advanced means of interfacing a spacecraft system with the PI and operators. Current automated capabilities include Web-based command submission, limited contact scheduling, command list generation and transfer to the ground station, spacecraft support for demonstrations experiments, data transfer from the ground station back to the ASSET system, data archiving, and Web-based telemetry distribution. Phase 2 was finished in December 1996. During January-December 1997 work was commenced on Phase 3 of the ASSET Project. Phase 3 is the subject of this report. This phase permitted SSDL and its project partners to expand the ASSET system in a variety of ways. These added capabilities included the advancement of ground station capabilities, the adaptation of spacecraft on-board software, and the expansion of capabilities of the ASSET management algorithms. Specific goals of Phase 3 were: (1) Extend Web-based goal-level commanding for both the payload PI and the spacecraft engineer; (2) Support prioritized handling of multiple PIs as well as associated payload experimenters; (3) Expand the number and types of experiments supported by the ASSET system and its associated spacecraft; (4) Implement more advanced resource

  16. World-wide sexual compatibility in Medfly, Ceratitis capitata (Wied.), and its implications for SIT

    International Nuclear Information System (INIS)

    Cayol, J.P.

    2000-01-01

    The concept of the sterile insect technique, described by Knipling (1953), to control and/or eradicate insect pest populations has been applied to many Lepidoptera and Diptera species. Among Diptera species, the Mediterranean fruit fly, Ceratitis capitata (Wied.) (Diptera: Tephritidae), is often referred to as the most important agricultural pest in the world (Liquido et al. 1990) and it is also a major target of SIT action programmes world-wide. The use of SIT requires that mass rearing facilities be developed to produce sterile insects for use in national programmes, with mass reared strains being established by colonising wild insects collected from the SIT target area. More recently, with the increasing demand for sterile Medflies and the limited number of production facilities, some rearing facilities began to export Medflies to other national/regional programmes. Eight facilities have now reached production levels which allow them to export sterile insects (Fisher and Caceres 199) on a regional or inter-regional basis. When this procedure is used, the flies released have to compete with wild flies of a different geographic origin. The increasing use of Medfly genetic sexing strains (GSS) has also resulted in the same strain being used in different countries. To date, five rearing facilities in the world produce GSS (Fisher and Caceres 1999). Since GSS are assembled from specific components, it is impossible to 'colonise' them from each country where sterile GSS flies are needed. The GSS are often backcrossed with insects from the target population to increase the genetic variability (Franz et al. 1996), although in some cases this presents problems (Franz, personal communication). In practice, a single wild population is used as a basis for the synthesis of the GSS. Consequently, the same GSS based on the same wild genetic material may be used in various countries/continents and the question was raised concerning the sexual compatibility of these strains with

  17. Test and calibration of the Digital World-Wide Standardized Seismograph

    1982-01-01

    During the past decade there has been steady progress in the modernization of the global seismograph network operated by the U.S. Geological Survey (USGS). The World-Wide Standardized Seismograph Network (WWSSN) has been augmented by new stations with advanced instrumentation, including the Seismic Research Observatories (SRO) and the modified High-Gain Long-Period (ASRO) stations. One goal in the modernization effort has been to improve signal resolution in the long-period band. A second goal has been to generate a global digital data base to support contemporary computer-based analysis and research. In 1976, a Panel on Seismograph Networks was established by the Committee on Seismology of the National Academy of Sciences to review progress in network seismology and recommend actions that would lead to an improved global data base for seismology. One recommendation in the Panel report (Engdahl, 1977) called for upgrading selected WWSSN stations by the installation of digital recorders. This was viewed as an economical way of expanding the digital network, which had proven itself to be a very promising new tool for earthquake and explosion research. Funds for the development and assembly of 15 digital recorders were provided to the USGS by the Defense Advanced Research Projects Agency and an ad Inoc panel of scientists was convened by the Committee on Seismology to advise the USGS on the selection of stations to be upgraded and on data recording requirements, A total of 19 digital World-Wide Standardized Seismograph (DWWSS) systems will be operational when all are installed. The additional systems were made available through purchase by the USGS and other organizations; for example, the University of Bergen purchased and installed a DWWSS-type recorder and agreed to furnish the USGS with the data. A list of operational and planned DWWSS network stations is given in Table 1.1.As one might expect, the digital recorder turned out to be somewhat more sophisticated than

    Full Text Available There is little published research on the role of consultants in technology adoption. Given the increasing popularity of the World Wide Web in commercial environments and the number of consultants now offering web development services, some analysis into the effects of their engagement would be of benefit. In an extension of an ongoing study, an existing sample of 113 World Wide Web adopters was used to examine the nature of World Wide Web site use with respect to consultant and Internet Service Provider (ISP engagement. Analysis was also conducted into the use of consultants and ISPs as developers and maintainers of these sites. This preliminary research finds a number of interesting outcomes. No significant relationship is found between consultant or ISP engagement and World Wide Web site use, regardless of whether the consultant was engaged as site developer or site maintainer. The study raises a number of additional findings that are of interest but are not directly related to this study. These findings merit further research.

    2002-01-01

    This study was undertaken to determine the quality of information on the Internet regarding laparoscopy. Four popular World Wide Web search engines were used with the key word "laparoscopy." Advertisements, patient- or physician-directed information, and controversial material were noted. A total of 14,030 Web pages were found, but only 104 were unique Web sites. The majority of the sites were duplicate pages, subpages within a main Web page, or dead links. Twenty-eight of the 104 pages had a medical product for sale, 26 were patient-directed, 23 were written by a physician or group of physicians, and six represented corporations. The remaining 21 were "miscellaneous." The 46 pages containing educational material were critically reviewed. At least one of the senior authors found that 32 of the pages contained controversial or misleading statements. All of the three senior authors (LKN, NAO, GAF) independently agreed that 17 of the 46 pages contained controversial information. The World Wide Web is not a reliable source for patient or physician information about laparoscopy. Authenticating medical information on the World Wide Web is a difficult task, and no government or surgical society has taken the lead in regulating what is presented as fact on the World Wide Web.

  9. ETDEWEB versus the World-Wide-Web: a specific database/web comparison

    Energy Technology Data Exchange (ETDEWEB)

    Cutler, Debbie

    2010-06-28

    A study was performed comparing user search results from the specialized scientific database on energy-related information, ETDEWEB, with search results from the internet search engines Google and Google Scholar. The primary objective of the study was to determine if ETDEWEB (the Energy Technology Data Exchange – World Energy Base) continues to bring the user search results that are not being found by Google and Google Scholar. As a multilateral information exchange initiative, ETDE’s member countries and partners contribute cost- and task-sharing resources to build the largest database of energy-related information in the world. As of early 2010, the ETDEWEB database has 4.3 million citations to world-wide energy literature. One of ETDEWEB’s strengths is its focused scientific content and direct access to full text for its grey literature (over 300,000 documents in PDF available for viewing from the ETDE site and over a million additional links to where the documents can be found at research organizations and major publishers globally). Google and Google Scholar are well-known for the wide breadth of the information they search, with Google bringing in news, factual and opinion-related information, and Google Scholar also emphasizing scientific content across many disciplines. The analysis compared the results of 15 energy-related queries performed on all three systems using identical words/phrases. A variety of subjects was chosen, although the topics were mostly in renewable energy areas due to broad international interest. Over 40,000 search result records from the three sources were evaluated. The study concluded that ETDEWEB is a significant resource to energy experts for discovering relevant energy information. For the 15 topics in this study, ETDEWEB was shown to bring the user unique results not shown by Google or Google Scholar 86.7% of the time. Much was learned from the study beyond just metric comparisons. Observations about the strengths of each

    1996-10-01

    Recent articles have identified the plethora of chemical information existing currently on the World-Wide Web (WWW) available via the Internet (1). This information medium is particularly valuable because it represents a very up-to-date source of information. Site managers can update information and it can be "instantaneously visited" by someone. As an example, several current topics of chemical significance were highlighted in a nonmajor chemistry class held in January 1996 at our college. December 31, 1995, represented the last day that leaded gasoline could be sold for use in automobiles. In early January, the FDA approved the synthetic fat olestra for use in snack foods. Both of these topics provoked great interest in students as they brought up issues of relevance and interest to their lives that were currently being discussed in the news. The WWW was utilized extensively as a source of information and current updates. Print media, such as texts and reference manuals, have a much longer "lag-time" before current information can be typeset, printed, and accessed by a researcher. Previous articles (1, 2) have focused on Internet use for upper-division classes, but we have found a useful way to bring the Internet into nonmajor and freshman level classes composed of 20-50 students. The student assignment was to find information on a chemical topic currently in the news by using the WWW and use that information to write a 2-3 page essay (3, 4). Using the Internet to find information presents one issue not previously encountered when using encyclopedias, reference books, or textbooks, but an issue raised in previous editorials in this Journal (5, 6). That difference is that virtually anyone can post information on the WWW. Thus, the WWW can have governmental organizations, environmental groups, large corporations, or just individuals posting their views. Hence, when searching a particular topic, students might find a very factual article, or they might find a very

    2016-01-01

    During the 227th American Astronomical Society meeting last week in Kissimmee, the AAS announced the exciting news that it will become the new institutional home of Microsofts WorldWide Telescope (WWT) astronomy software.WWT is a scriptable and interactive way of browsing the multi-wavelength sky as it is seen from Earth, and the universe as we would travel within it. WWT can be run either as a desktop app or from within an internet browser. And of interest to researchers especially its an incredibly useful way to visualize and contextualize astronomical data.What does WWTs transition to the AAS as its new host mean? WWT was open-sourced by Microsoft Research last year, and hosting by the AAS will permit broad community involvement in the form of contribution of both code and guidance in WWTs further development.All of this begs the question: why might YOU want to use WWT? That depends on whether your goal is to use it for research, education, or just for fun.WWT for ResearchIfyou thought WWT was just for education and outreach, think again! Here are just a few things you can do with WWT to advance your astronomical research1:1) Put surveys into context, on top of more than 40 different all-sky images, spanning the electromagnetic spectrum.2) Perform literature searches from the sky.3) Compare images and catalogs at different wavelengths, on-the-fly in seconds.4) Show your own online data to the world, in an API that allows users to see it on the sky in their browsers.5) Communicate to colleagues and learners about the sky using interactive tours of your data and ideas.An example of WWT used to perform astronomy research is the recently highlighted work on the bones of the Milky Way, in which the authors used WWT to overlay multiple data sets and visually identify and then search for infrared dark clouds along the predicted positions of Milky Way spiral arms.An example of WWT used to communicate research is given in this paper, wherein a link in the caption of a

    2001-01-01

    This editorial provides a model of how quality initiatives concerned with health information on the World Wide Web may in the future interact with each other. This vision fits into the evolving "Semantic Web" architecture - ie, the prospective that the World Wide Web may evolve from a mess of unstructured, human-readable information sources into a global knowledge base with an additional layer providing richer and more meaningful relationships between resources. One first prerequisite for forming such a "Semantic Web" or "web of trust" among the players active in quality management of health information is that these initiatives make statements about themselves and about each other in a machine-processable language. I present a concrete model on how this collaboration could look, and provide some recommendations on what the role of the World Health Organization (WHO) and other policy makers in this framework could be.

    Iodine-129 is one of the radioisotopes which have seen significant increases in the environment since the beginning of the nuclear age. Other prominent representatives of this group include tritium, 14 C and 36 Cl. Most members of this group have gone through a cycle of initial release (associated mainly with atmospheric bomb tests during the late fifties and early sixties) and subsequent decay (e.g. T) or dispersion (e.g. 14 C and 36 Cl) so that their concentrations are again close to pre-anthropogenic levels. 129 I has, however, remained at significantly elevated levels even after the stop of nuclear weapon tests

    1988-01-01

    In a study of one million years of Middle Miocene sediment deposition in ODP Hole 689B in the Weddell Sea near Antarctica, a single iridium (Ir) anomaly of 44 (+ or - 10) x 10 to the 12th gram Ir per gram rock (ppt) was observed in core 6H, section 3, 50 to 60 cm, after background contributions associated with manganese precipitates and clay are subtracted. The ODP Hole 689B is 10,000 km away from another site, DSDP Hole 588B in the Tasman Sea north of New Zealand, where a single Ir anomaly of 144 + or - 7 ppt over a background of 11 ppt was found in an earlier study of 3 million years of deposition. From chemical measurements the latter deposition was thought to be impact-related. Ir measurements were made, following neutron activation, with the Iridium Coincidence Spectrometer. The age vs depth calibration curves given in the DSDP and ODP preliminary reports indicate the ages of the Iranomalies are identical, 11.7 million years, but the absolute and relative uncertainties in the curves are not known. Based on the newest age data the age estimate is 10 million years. As the Ir was deposited at the two sites at about the same time and they are one quarter of the way around the world from each other it seems likely that the deposition was world-wide. The impact of a large asteroid or comet could produce the wide distribution, and this data is supportive of the impact relationship deduced for Deep Sea Drilling Project (DSDP) 588B from the chemical evidence. If the surface densities of Ir at the two sites are representative of the world-wide average, the diameter of a Cl type asteroid containing the necessary Ir would be 3 + or - 1 km, which is large enough to cause world-wide darkness and hence extinctions although the latter point is disputed.

    The web can be regarded as an ecosystem of digital resources connected and shaped by collective successive behaviors of users. Knowing how people allocate limited attention on different resources is of great importance. To answer this, we embed the most popular Chinese web sites into a high dimensional Euclidean space based on the open flow network model of a large number of Chinese users' collective attention flows, which both considers the connection topology of hyperlinks between the sites and the collective behaviors of the users. With these tools, we rank the web sites and compare their centralities based on flow distances with other metrics. We also study the patterns of attention flow allocation, and find that a large number of web sites concentrate on the central area of the embedding space, and only a small fraction of web sites disperse in the periphery. The entire embedding space can be separated into 3 regions(core, interim, and periphery). The sites in the core (1%) occupy a majority of the attention flows (40%), and the sites (34%) in the interim attract 40%, whereas other sites (65%) only take 20% flows. What's more, we clustered the web sites into 4 groups according to their positions in the space, and found that similar web sites in contents and topics are grouped together. In short, by incorporating the open flow network model, we can clearly see how collective attention allocates and flows on different web sites, and how web sites connected each other.

We also study the patterns of attention flow allocation, and find that a large number of web sites concentrate on the central area of the embedding space, and only a small fraction of web sites disperse in the periphery. The entire embedding space can be separated into 3 regions(core, interim, and periphery). The sites in the core (1%) occupy a majority of the attention flows (40%), and the sites (34%) in the interim attract 40%, whereas other sites (65%) only take 20% flows. What’s more, we clustered the web sites into 4 groups according to their positions in the space, and found that similar web sites in contents and topics are grouped together. In short, by incorporating the open flow network model, we can clearly see how collective attention allocates and flows on different web sites, and how web sites connected each other. PMID:27812133

    Full Text Available In a world where the internet and its image are becoming more and more important, this study is about the importance of Investment and Financial Services Companies web sites. Market competition, creates the need of studies, focused on assessing and analyzing the websites of companies who are active in this sector. Our study wants to respond at several questions related to Romanian Investment and Financial Services Companies web sites through four dimensions: content, layout, handling and interactivity. Which web sites are best and from what point of view? Where should financial services companies direct their investments to differentiate themselves and their sites? In fact we want to rank the 58 Investment and Financial Services Companies web sites based on 127 criteria. There are numerous methods for evaluating web pages. The evaluation methods are similar from the structural point of view and the most popular are: Serqual, Sitequal, Webqual / Equal EtailQ, Ewam, e-Serqual, WebQEM (Badulescu, 2008:58. In the paper: "Assessment of Romanian Banks E-Image: A Marketing Perspective" (Catana, Catana and Constantinescu, 2006: 4 the authors point out that there are at least four complex variables: accessibility, functionality, performance and usability. Each of these can be decomposed into simple ones. We used the same method, and we examined from the utility point of view, 58 web sites of Investment and Financial Services Companies based on 127 criteria following a procedure developed by Institut fur ProfNet Internet Marketing, Munster (Germany. The data collection period was 1-30 September 2010. The results show that there are very large differences between corporate sites; their creators are concentrating on the information required by law and aesthetics, neglecting other aspects as communication and online service. In the future we want to extend this study at international level, by applying the same methods of research in 5 countries from

    Visualization tools for biological data are often limited in their ability to interactively integrate data at multiple scales. These computational tools are also typically limited by two-dimensional displays and programmatic implementations that require separate configurations for each of the user's computing devices and recompilation for functional expansion. Towards overcoming these limitations we have developed "ePlant" (http://bar.utoronto.ca/eplant) - a suite of open-source world wide web-based tools for the visualization of large-scale data sets from the model organism Arabidopsis thaliana. These tools display data spanning multiple biological scales on interactive three-dimensional models. Currently, ePlant consists of the following modules: a sequence conservation explorer that includes homology relationships and single nucleotide polymorphism data, a protein structure model explorer, a molecular interaction network explorer, a gene product subcellular localization explorer, and a gene expression pattern explorer. The ePlant's protein structure explorer module represents experimentally determined and theoretical structures covering >70% of the Arabidopsis proteome. The ePlant framework is accessed entirely through a web browser, and is therefore platform-independent. It can be applied to any model organism. To facilitate the development of three-dimensional displays of biological data on the world wide web we have established the "3D Data Display Initiative" (http://3ddi.org).

    The purpose of this project was to compare student outcomes in an undergraduate research course taught using both World Wide Web-based distance learning technology and traditional pedagogy. Reasons given for enrolling in the traditional classroom section included the perception of increased opportunity for interaction, decreased opportunity to procrastinate, immediate feedback, and more meaningful learning activities. Reasons for selecting the Web group section included cost, convenience, and flexibility. Overall, there was no significant difference in examination scores between the two groups on the three multiple-choice examinations or for the course grades (t = -.96, P = .343). Students who reported that they were self-directed and had the ability to maintain their own pace and avoid procrastination were most suited to Web-based courses. The Web-based classes can help provide opportunities for methods of communication that are not traditionally nurtured in traditional classroom settings. Secondary benefits of the World Wide Web-based course were to increase student confidence with the computer, and introduce them to skills and opportunities they would not have had in the classroom. Additionally, over time and with practice, student's writing skills improved.

    To design and develop a World Wide Web-based education program that will allow trainees to interactively learn and improve the diagnostic capability of detecting pulmonary nodules on chest radiographs. Chest radiographs with known diagnosis were retrieved and selected from our institutional clinical archives. A database was constructed by sorting radiographs into three groups: normal, nodule, and false positive (i.e., nodule-like focal opacity). Each nodule was assigned with the degree of detectability: easy, intermediate, difficult, and likely missed. Nodules were characterized by their morphology (well-defined, ill-defined, irregular, faint) and by other associated pathologies or potentially obscuring structures. The Web site was organized into four sections: study, test, record and information. The Web site allowed a user interactively to undergo the training section appropriate to the user's diagnostic capability. The training was enhanced by means of clinical and other pertinent radiological findings included in the database. The outcome of the training was tested with clinical test radiographs that presented nodules or false positives with varying diagnostic difficulties. A World Wide Web-based education program is a promising technique that would allow trainees to interactively learn and improve the diagnostic capability of detecting and characterizing pulmonary nodules

    Software-based medical knowledge packages (MKPs) are packages of highly structured medical knowledge that can be integrated into various health-care information systems or the World Wide Web. They have been established to provide different forms of clinical decision support such as textual interpretation of combinations of laboratory rest results, generating diagnostic hypotheses as well as confirmed and excluded diagnoses to support differential diagnosis in internal medicine, or for early identification and automatic monitoring of hospital-acquired infections. Technically, an MKP may consist of a number of inter-connected Arden Medical Logic Modules. Several MKPs have been integrated thus far into hospital, laboratory, and departmental information systems. This has resulted in useful and widely accepted software-based clinical decision support for the benefit of the patient, the physician, and the organization funding the health care system.

    Studies of the use of the World Wide Web to obtain medical knowledge have largely focused on patients. In particular, neither the international use of academic nephrology World Wide Web sites (websites) as primary information sources nor the use of search engines (and search strategies) to obtain medical information have been described. Visits ("hits") to the Walter Reed Army Medical Center (WRAMC) Nephrology Service website from April 30, 2000, to March 14, 2001, were analyzed for the location of originating source using Webtrends, and search engines (Google, Lycos, etc.) were analyzed manually for search strategies used. From April 30, 2000 to March 14, 2001, the WRAMC Nephrology Service website received 1,007,103 hits and 12,175 visits. These visits were from 33 different countries, and the most frequent regions were Western Europe, Asia, Australia, the Middle East, Pacific Islands, and South America. The most frequent organization using the site was the military Internet system, followed by America Online and automated search programs of online search engines, most commonly Google. The online lecture series was the most frequently visited section of the website. Search strategies used in search engines were extremely technical. The use of "robots" by standard Internet search engines to locate websites, which may be blocked by mandatory registration, has allowed users worldwide to access the WRAMC Nephrology Service website to answer very technical questions. This suggests that it is being used as an alternative to other primary sources of medical information and that the use of mandatory registration may hinder users from finding valuable sites. With current Internet technology, even a single service can become a worldwide information resource without sacrificing its primary customers.

    People with cystic fibrosis (CF) generate Pseudomonas aeruginosa in droplet nuclei during coughing. The use of surgical masks has been recommended in healthcare settings to minimize pathogen transmission between patients with CF. To determine if face masks and cough etiquette reduce viable P. aeruginosa aerosolized during coughing. Twenty-five adults with CF and chronic P. aeruginosa infection were recruited. Participants performed six talking and coughing maneuvers, with or without face masks (surgical and N95) and hand covering the mouth when coughing (cough etiquette) in an aerosol-sampling device. An Andersen Cascade Impactor was used to sample the aerosol at 2 meters from each participant. Quantitative sputum and aerosol bacterial cultures were performed, and participants rated the mask comfort levels during the cough maneuvers. During uncovered coughing (reference maneuver), 19 of 25 (76%) participants produced aerosols containing P. aeruginosa, with a positive correlation found between sputum P. aeruginosa concentration (measured as cfu/ml) and aerosol P. aeruginosa colony-forming units. There was a reduction in aerosol P. aeruginosa load during coughing with a surgical mask, coughing with an N95 mask, and cough etiquette compared with uncovered coughing (P masks during coughing; yet, participants rated the surgical masks as more comfortable (P = 0.013). Cough etiquette provided approximately half the reduction of viable aerosols of the mask interventions during voluntary coughing. Talking was a low viable aerosol-producing activity. Face masks reduce cough-generated P. aeruginosa aerosols, with the surgical mask providing enhanced comfort. Cough etiquette was less effective at reducing viable aerosols.

  13. Affordances of students' using the World Wide Web as a publishing medium in project-based learning environments

    Science.gov (United States)

    Bos, Nathan Daniel

    This dissertation investigates the emerging affordance of the World Wide Web as a place for high school students to become authors and publishers of information. Two empirical studies lay groundwork for student publishing by examining learning issues related to audience adaptation in writing, motivation and engagement with hypermedia, design, problem-solving, and critical evaluation. Two models of student publishing on the World Wide Web were investigated over the course of two 11spth grade project-based science curriculums. In the first curricular model, students worked in pairs to design informative hypermedia projects about infectious diseases that were published on the Web. Four case studies were written, drawing on both product- and process-related data sources. Four theoretically important findings are illustrated through these cases: (1) multimedia, especially graphics, seemed to catalyze some students' design processes by affecting the sequence of their design process and by providing a connection between the science content and their personal interest areas, (2) hypermedia design can demand high levels of analysis and synthesis of science content, (3) students can learn to think about science content representation through engagement with challenging design tasks, and (4) students' consideration of an outside audience can be facilitated by teacher-given design principles. The second Web-publishing model examines how students critically evaluate scientific resources on the Web, and how students can contribute to the Web's organization and usability by publishing critical reviews. Students critically evaluated Web resources using a four-part scheme: summarization of content, content, evaluation of credibility, evaluation of organizational structure, and evaluation of appearance. Content analyses comparing students' reviews and reviewed Web documents showed that students were proficient at summarizing content of Web documents, identifying their publishing

    The 2- to 6-page print journal article has been the standard for 200 years, yet this format severely limits the amount of detailed information that can be conveyed. The World Wide Web provides a low-cost option for posting extended text and supplementary information. It also can enhance the experience of journal editors, reviewers, readers, and authors through added functionality (eg, online submission and peer review, postpublication critique, and e-mail notification of table of contents.) Our aim was to characterize ways that journals were using the World Wide Web in 2005 and note changes since 2003. We analyzed the Web sites of 138 high-impact print journals in 3 ways. First, we compared the print and Web versions of March 2003 and 2005 issues of 28 journals (20 of which were randomly selected from the 138) to determine how often articles were published Web only and how often print articles were augmented by Web-only supplements. Second, we examined what functions were offered by each journal Web site. Third, for journals that offered Web pages for reader commentary about each article, we analyzed the number of comments and characterized these comments. Fifty-six articles (7%) in 5 journals were Web only. Thirteen of the 28 journals had no supplementary online content. By 2005, several journals were including Web-only supplements in >20% of their papers. Supplementary methods, tables, and figures predominated. The use of supplementary material increased by 5% from 2% to 7% in the 20-journal random sample from 2003 to 2005. Web sites had similar functionality with an emphasis on linking each article to related material and e-mailing readers about activity related to each article. There was little evidence of journals using the Web to provide readers an interactive experience with the data or with each other. Seventeen of the 138 journals offered rapid-response pages. Only 18% of eligible articles had any comments after 5 months. Journal Web sites offer similar

    To establish a new visual educational system of virtual reality for clinical dentistry based on world wide web (WWW) webpage in order to provide more three-dimensional multimedia resources to dental students and an online three-dimensional consulting system for patients. Based on computer graphics and three-dimensional webpage technologies, the software of 3Dsmax and Webmax were adopted in the system development. In the Windows environment, the architecture of whole system was established step by step, including three-dimensional model construction, three-dimensional scene setup, transplanting three-dimensional scene into webpage, reediting the virtual scene, realization of interactions within the webpage, initial test, and necessary adjustment. Five cases of three-dimensional interactive webpage for clinical dentistry were completed. The three-dimensional interactive webpage could be accessible through web browser on personal computer, and users could interact with the webpage through rotating, panning and zooming the virtual scene. It is technically feasible to implement the visual educational system of virtual reality for clinical dentistry based on WWW webpage. Information related to clinical dentistry can be transmitted properly, visually and interactively through three-dimensional webpage.

  16. How Did I Get to Princess Margaret? (And How Did I Get Her to the World Wide Web?

    Directory of Open Access Journals (Sweden)

    Kip Jones

    2007-09-01

    Full Text Available The paper explores the growing use of tools from the arts and humanities for investigation and dissemination of social science research. Emerging spaces for knowledge transfer, such as the World Wide Web, are explored as outlets for "performative social science". Questions of ethnics and questions of evaluation which emerge from performative social science and the use of new technologies are discussed. Contemporary thinking in aesthetics is explored to answer questions of evaluation. The use of the Internet for productions is proposed as supporting the collective elaboration of meaning supported by Relational Aesthetics. One solution to the ethical problem of performing the narrations of others is the use of the writer's own story as autoethnography. The author queries autoethnography's tendency to tell "sad" stories and proposes an amusing story, exemplified by "The One about Princess Margaret" (see http://www.qualitative-research.net/index.php/fqs/rt/suppFiles/281/618. The conclusion is reached that the free and open environment of the Internet sidelines the usual tediousness of academic publishing and begins to explore new answers to questions posed about the evaluation and ethics of performative social science.

    Nanomachine and molecular machines are state-of-the-art objects in current physics and chemistry. The operation and manufacturing of nanosize machines are top-level technologies that we have desired to accomplish for a long time. There have been extensive attempts to design and synthesize nanomachines. In this paper, we review the these attempts using the concept of nanoarchitectonics toward the design, synthesis, and testing of molecular machinery, especially at interfacial media. In the first half of this review, various historical attempts to design and prepare nanomachines are introduced as well as their operation mechanisms from their basic principles. Furthermore, in order to emphasize the importance and possibilities of this research field, we also give examples of two new challenging topics in the second half of this review: (i) a world wide nanocar race and (ii) new modes of nanomachine operation on water. The nanocar race event involves actual use of nanomachines and will take place in the near future, and nanomachine operation of a dynamic fluidic interface will enable future advances in nanomachine science and technology.

    Surveys on technical information relevant to the gas industry showed that no single information source was sufficient for all needs, while a number of sources include some pertinent information as part of their mission. The surveys concluded that access was difficult and wide usage of electronic resources had some real as well as some perceived problems. With the availability of the Internet and World Wide Web, many of these difficulties are being overcome. The natural gas industry is moving rapidly toward an era of electronic information with global access to a wide variety of technical, financial, and operational information. The most important sources of technical information are reviewed, and access to resources is briefly described. Cost comparison, relevancy, ease of use, and other factors are also discussed. The current status and future developments of gas industry information resources and technology are addressed in terms of emerging technologies and management issues which will bring critical information to the desktop of engineers, planners, and marketers.

    Objectives To determine the characteristics of popular breast cancer related websites and whether more popular sites are of higher quality. Design The search engine Google was used to generate a list of websites about breast cancer. Google ranks search results by measures of link popularity—the number of links to a site from other sites. The top 200 sites returned in response to the query “breast cancer” were divided into “more popular” and “less popular” subgroups by three different measures of link popularity: Google rank and number of links reported independently by Google and by AltaVista (another search engine). Main outcome measures Type and quality of content. Results More popular sites according to Google rank were more likely than less popular ones to contain information on ongoing clinical trials (27% v 12%, P=0.01 ), results of trials (12% v 3%, P=0.02), and opportunities for psychosocial adjustment (48% v 23%, Ppopular sites by number of linking sites were also more likely to provide updates on other breast cancer research, information on legislation and advocacy, and a message board service. Measures of quality such as display of authorship, attribution or references, currency of information, and disclosure did not differ between groups. Conclusions Popularity of websites is associated with type rather than quality of content. Sites that include content correlated with popularity may best meet the public's desire for information about breast cancer. What is already known on this topicPatients are using the world wide web to search for health informationBreast cancer is one of the most popular search topicsCharacteristics of popular websites may reflect the information needs of patientsWhat this study addsType rather than quality of content correlates with popularity of websitesMeasures of quality correlate with accuracy of medical information PMID:11884322

    As we all know too well, building up a collaborative community around a software infrastructure is not easy. Besides recruiting enthusiasts to work as part of it, mostly for free, to succeed you also need to overcome a number of technical, sociological, and, to our surprise, some political hurdles. The ALMA Common Software (ACS) was developed at ESO and partner institutions over the course of more than 10 years. While it was mainly intended for the ALMA Observatory, it was early on thought as a generic distributed control framework. ACS has been periodically released to the public through an LGPL license, which encouraged around a dozen non-ALMA institutions to make use of ACS for both industrial and educational applications. In recent years, the Cherenkov Telescope Array and the LLAMA Observatory have also decided to adopt the framework for their own control systems. The aim of the "ACS Community" is to support independent initiatives in making use of the ACS framework and to further contribute to its development. The Community provides access to a growing network of volunteers eager to develop ACS in areas that are not necessarily in ALMA's interests, and/or were not within the original system scope. Current examples are: support for additional OS platforms, extension of supported hardware interfaces, a public code repository and a build farm. The ACS Community makes use of existing collaborations with Chilean and Brazilian universities, reaching out to promising engineers in the making. At the same time, projects actively using ACS have committed valuable resources to assist the Community's work. Well established training programs like the ACS Workshops are also being continued through the Community's work. This paper aims to give a detailed account of the ongoing (second) journey towards establishing a world-wide open source collaboration around ACS. The ACS Community is growing into a horizontal partnership across a decentralized and diversified group of

    In the frame of the present preoccupation on the global climatic change and its influence in the human activities, the possible mitigation scenarios of green house effect gases are analyzed (GEG) in the world-wide scope, the contribution of carbon dioxide future emissions as main green house effect gas originating from the burning of fossil fuels; taking into account two large classifications: Developed and developing countries. In accordance with the world-wide evolution in the 1972-1995 period and to diverse adjustments of future emissions a study of the necessary levels of these emissions is made to obtain the stabilization of the greenhouse effect gases in the atmosphere in a level in the vicinity of 550 ppmv. The considered projections are: emissions in accordance with the present tendency, basic scenario of the Intergovernmental Panel of Climatic Change (Panel Intergubernamental de Cambio Climatico) (IPCC-IS92a), mitigation proposals of the Netherlands (NL-1%, NL-2%) and profiles that entail the atmospheric CO{sub 2} stabilization. In addition the reduction in the contribution of future emissions that the developing countries would have to face to obtain the stabilization are compared, emissions that will depend on changes in factors such as population growth, economic, emissions per capita and carbon content of the power fuels, changes that would have to take place in all the countries, or certain key countries, in order to arrive to the necessary atmospheric stabilization of the emissions in accordance with those profiles.

    Full Text Available Abstract Background Main waterfowl migration systems are well understood through ringing activities. However, in mallards (Anas platyrhynchos ringing studies suggest deviations from general migratory trends and traditions in waterfowl. Furthermore, surprisingly little is known about the population genetic structure of mallards, and studying it may yield insight into the spread of diseases such as Avian Influenza, and in management and conservation of wetlands. The study of evolution of genetic diversity and subsequent partitioning thereof during the last glaciation adds to ongoing discussions on the general evolution of waterfowl populations and flyway evolution. Hypothesised mallard flyways are tested explicitly by analysing mitochondrial mallard DNA from the whole northern hemisphere. Results Phylogenetic analyses confirm two mitochondrial mallard clades. Genetic differentiation within Eurasia and North-America is low, on a continental scale, but large differences occur between these two land masses (FST = 0.51. Half the genetic variance lies within sampling locations, and a negligible portion between currently recognised waterfowl flyways, within Eurasia and North-America. Analysis of molecular variance (AMOVA at continent scale, incorporating sampling localities as smallest units, also shows the absence of population structure on the flyway level. Finally, demographic modelling by coalescence simulation proposes a split between Eurasia and North-America 43,000 to 74,000 years ago and strong population growth (~100fold since then and little migration (not statistically different from zero. Conclusions Based on this first complete assessment of the mallard's world-wide population genetic structure we confirm that no more than two mtDNA clades exist. Clade A is characteristic for Eurasia, and clade B for North-America although some representatives of clade A are also found in North-America. We explain this pattern by evaluating competing

    The quality of consumer health information on the World Wide Web is an important issue for medicine, but to date no systematic and comprehensive synthesis of the methods and evidence has been performed. To establish a methodological framework on how quality on the Web is evaluated in practice, to determine the heterogeneity of the results and conclusions, and to compare the methodological rigor of these studies, to determine to what extent the conclusions depend on the methodology used, and to suggest future directions for research. We searched MEDLINE and PREMEDLINE (1966 through September 2001), Science Citation Index (1997 through September 2001), Social Sciences Citation Index (1997 through September 2001), Arts and Humanities Citation Index (1997 through September 2001), LISA (1969 through July 2001), CINAHL (1982 through July 2001), PsychINFO (1988 through September 2001), EMBASE (1988 through June 2001), and SIGLE (1980 through June 2001). We also conducted hand searches, general Internet searches, and a personal bibliographic database search. We included published and unpublished empirical studies in any language in which investigators searched the Web systematically for specific health information, evaluated the quality of Web sites or pages, and reported quantitative results. We screened 7830 citations and retrieved 170 potentially eligible full articles. A total of 79 distinct studies met the inclusion criteria, evaluating 5941 health Web sites and 1329 Web pages, and reporting 408 evaluation results for 86 different quality criteria. Two reviewers independently extracted study characteristics, medical domains, search strategies used, methods and criteria of quality assessment, results (percentage of sites or pages rated as inadequate pertaining to a quality criterion), and quality and rigor of study methods and reporting. Most frequently used quality criteria used include accuracy, completeness, readability, design, disclosures, and references provided

    Antimicrobial stewardship programs aim to reduce inappropriate hospital antimicrobial use. At the Johns Hopkins Children's Medical and Surgical Center (Baltimore, MD), we implemented a World Wide Web-based antimicrobial restriction program to address problems with the existing restriction program. A user survey identified opportunities for improvement of an existing antimicrobial restriction program and resulted in subsequent design, implementation, and evaluation of a World Wide Web-based antimicrobial restriction program at a 175-bed, tertiary care pediatric teaching hospital. The program provided automated clinical decision support, facilitated approval, and enhanced real-time communication among prescribers, pharmacists, and pediatric infectious diseases fellows. Approval status, duration, and rationale; missing request notifications; and expiring approvals were stored in a database that is accessible via a secure Intranet site. Before and after implementation of the program, user satisfaction, reports of missed and/or delayed doses, antimicrobial dispensing times, and cost were evaluated. After implementation of the program, there was a $370,069 reduction in projected annual cost associated with restricted antimicrobial use and an 11.6% reduction in the number of dispensed doses. User satisfaction increased from 22% to 68% and from 13% to 69% among prescribers and pharmacists, respectively. There were 21% and 32% reductions in the number of prescriber reports of missed and delayed doses, respectively, and there was a 37% reduction in the number of pharmacist reports of delayed approvals; measured dispensing times were unchanged (P = .24). In addition, 40% fewer restricted antimicrobial-related phone calls were noted by the pharmacy. The World Wide Web-based antimicrobial approval program led to improved communication, more-efficient antimicrobial administration, increased user satisfaction, and significant cost savings.

    2014-03-01

    Full Text Available This paper assesses world-wide patterns of material extraction, trade, consumption and productivity based on a new data set for economy-wide material flows, covering used materials for all countries world-wide between 1980 and 2009. We show that global material extraction has grown by more than 90% over the past 30 years and is reaching almost 70 billion tonnes today. Also, trade volumes in physical terms have increased by a factor of 2.5 over the past 30 years, and in 2009, 9.3 billion tonnes of raw materials and products were traded around the globe. China has turned into the biggest consumer of materials world-wide and together with the US, India, Brazil and Russia, consumes more than 50% of all globally extracted materials. We also show that the per-capita consumption levels are very uneven, with a factor of more than 60 between the country with the lowest and highest consumption in 2009. On average, each human being consumed 10 tonnes of materials in 2009, 2 tonnes more than in 1980. We discuss whether decoupling of economies’ growth from resource use has occurred and analyse interrelations of material use with human development. Finally, we elaborate on key environmental problems related to various material groups.

    Although the Internet is already a valuable information resource in medicine, there are important challenges to be faced before physicians and general users will have extensive access to this information. As a result of a research effort to compile a health-related Internet directory, new tools and strategies have been developed to solve key problems derived from the explosive growth of medical information on the Net and the great concern over the quality of such critical information. The current Internet search engines lack some important capabilities. We suggest using second generation tools (client-side based) able to deal with large quantities of data and to increase the usability of the records recovered. We tested the capabilities of these programs to solve health-related information problems, recognising six groups according to the kind of topics addressed: Z39.50 clients, downloaders, multisearchers, tracing agents, indexers and mappers. The evaluation of the quality of health information available on the Internet could require a large amount of human effort. A possible solution may be to use quantitative indicators based on the hypertext visibility of the Web sites. The cybermetric measures are valid for quality evaluation if they are derived from indirect peer review by experts with Web pages citing the site. The hypertext links acting as citations need to be extracted from a controlled sample of quality super-sites.

  9. Implementation of a reference standard and proficiency testing programme by the World Wide Antimalarial Resistance Network (WWARN

    2010-12-01

    Full Text Available Abstract Background The Worldwide Antimalarial Resistance Network (WWARN is a global collaboration to support the objective that anyone affected by malaria receives effective and safe drug treatment. The Pharmacology module aims to inform optimal anti-malarial drug selection. There is an urgent need to define the drug exposure - effect relationship for most anti-malarial drugs. Few anti-malarials have had their therapeutic blood concentration levels defined. One of the main challenges in assessing safety and efficacy data in relation to drug concentrations is the comparability of data generated from different laboratories. To explain differences in anti-malarial pharmacokinetics in studies with different measurement laboratories it is necessary to confirm the accuracy of the assay methods. This requires the establishment of an external quality assurance process to assure results that can be compared. This paper describes this process. Methods The pharmacology module of WWARN has established a quality assurance/quality control (QA/QC programme consisting of two separate components: 1. A proficiency testing programme where blank human plasma spiked with certified reference material (CRM in different concentrations is sent out to participating bioanalytical laboratories. 2. A certified reference standard programme where accurately weighed amounts of certified anti-malarial reference standards, metabolites, and internal standards are sent to participating bioanalytical and in vitro laboratories. Conclusion The proficiency testing programme is designed as a cooperative effort to help participating laboratories assess their ability to carry out drug analysis, resolve any potential problem areas and to improve their results - and, in so doing, to improve the quality of anti-malarial pharmacokinetic data published and shared with WWARN. By utilizing the same source of standards for all laboratories, it is possible to minimize bias arising from poor

    Nuclear Technology Products (NTP) a business division of the South African Nuclear Energy Corporation Ltd. (NECSA) is today a leading supplier of a range or radioisotope and supporting products to markets throughout the world. To achieve this status in the face of large technological, logistical and business barriers to entry has required the development of integrated and effective processes from a diverse and unconsolidated range of expertise and other resources. The various facilities and competencies established at NECSA over a period of 40 years had as their objective the accomplishment of strictly non-commercial strategic imperatives. Major emphasis was placed at Pelindaba on development of the capability to beneficiate the country's resources of uranium which are extracted as a by-product of gold mining. Fuel enrichment processes (using a method unique to NECSA) and nuclear fuel fabrication facilities were developed and commissioned during the period 1975 - 1990 and substantial quantities of enriched and depleted uranium material was produced. A small amount of locally produced, highly enriched fuel has been used to power the 20 MW SARARI -1 Research Reactor at Pelindaba which has been in operation since 1965. Major political and economic changes affecting South Africa gave rise, in the late 1980s, to the necessity for a fundamental strategic reorientation of NECSA. Over a period of time the fuel enrichment and fabrication programmes were terminated and ever greater emphasis was placed on development of businesses from established, diverse facilities and competencies with the objective of promoting increased financial independence and long term viability for the organisation. It was at this time that NTP the business responsible for production and marketing of radiation-based products at NECSA, was established. The various developments which facilitated the capacity of NTP to accede to its current position as a significant and growing provider of

    Kevin A. Thayer

    2013-08-01

    Full Text Available This essay introduces the rhetorical concept of “morphos”, a dimension of ethos, in the context of cyborg self-transformation and cyborg storytelling. Focusing on the cyborg storytelling of Michael Chorost, a cochlear implant user and futurist, this essay applies "morphos" to develop an argument about the changing capabilities and changing stories of living cyborg authors. Using rhetorical concepts to illuminate his self-transformation and narrative constructions, this essay analyzes Chorost’s two books: Rebuilt: How Becoming Part Computer Made Me More Human; and, World Wide Mind: The Coming Integration of Humanity, Machines, and the Internet. Chorost’s first book, Rebuilt, is an autobiographical account of his journey from deafness to cochlear implant hearing and his quest for community. He completes his journey of self-transformation using Haraway’s Cyborg Manifesto and Caidin’s Cyborg as narrative tools. Rebuilt can be defined as a cyborg metapathography, identifying rhetorical features of Chorost’s cyborg storytelling. Chorost’s second book, World Wide Mind, is both autobiographical and theoretical. This rhetorical shift in the context of his changing physical, perceptual, and cognitive capabilities, and his changing ethos, is significant because it opens the way for a new hybrid language combining the spoken/written and digital code.

    The Internet has become a major source of health information for women, but information placed on the World Wide Web does not routinely undergo a peer review process before dissemination. In this study, we present an analysis of 197 infertility-related Web sites for quality and accountability, using JAMA's minimal core standards for responsible print. Only 2% of the web sites analyzed met all four recommended standards, and 50.8% failed to report any of the four. Commercial web sites were more likely to fail to meet minimum standards (71.2%) than those with educational (46.8%) or supportive (29.8%) elements. Web sites with educational and informational components were most common (70.6%), followed by commercial sites (52.8%) and sites that offered a forum for infertility support and activism (28.9%). Internet resources available to infertile patients are at best variable. The current state of infertility-related materials on the World Wide Web offers unprecedented opportunities to improve services to a growing number of e-health users. Because of variations in quality of site content, women's health clinicians must assume responsibility for a new role as information monitor. This study provides assessment tools clinicians can apply and share with clients.

    On the basis of ab initio computer simulations, pre-melting phenomena have been suggested to occur in the elastic properties of hexagonal close-packed iron under the conditions of the Earth's inner core just before melting. The extent to which these pre-melting effects might also occur in the physical properties of face-centred cubic metals has been investigated here under more experimentally accessible conditions for gold, allowing for comparison with future computer simulations of this material. The thermal expansion of gold has been determined by X-ray powder diffraction from 40 K up to the melting point (1337 K). For the entire temperature range investigated, the unit-cell volume can be represented in the following way: a second-order Grüneisen approximation to the zero-pressure volumetric equation of state, with the internal energy calculated via a Debye model, is used to represent the thermal expansion of the 'perfect crystal'. Gold shows a nonlinear increase in thermal expansion that departs from this Grüneisen-Debye model prior to melting, which is probably a result of the generation of point defects over a large range of temperatures, beginning at T / T m > 0.75 (a similar homologous T to where softening has been observed in the elastic moduli of Au). Therefore, the thermodynamic theory of point defects was used to include the additional volume of the vacancies at high temperatures ('real crystal'), resulting in the following fitted parameters: Q = ( V 0 K 0 )/γ = 4.04 (1) × 10 -18  J, V 0 = 67.1671 (3) Å 3 , b = ( K 0 ' - 1)/2 = 3.84 (9), θ D = 182 (2) K, ( v f /Ω)exp( s f / k B ) = 1.8 (23) and h f = 0.9 (2) eV, where V 0 is the unit-cell volume at 0 K, K 0 and K 0 ' are the isothermal incompressibility and its first derivative with respect to pressure (evaluated at zero pressure), γ is a Grüneisen parameter, θ D is the Debye temperature, v f , h f and s f are the vacancy formation volume, enthalpy and entropy

    The three international organizations, IAEA, FAO, and UNESCO, which jointly sponsored the Symposium, share an active interest and involvement in information systems development. The extent of their interest was explained by the Director General of the IAEA, Dr. Sigvard Eklund, when he opened the meeting on behalf of the three co-sponsors: UNESCO in conjunction with the International Council of Scientific Unions (ICSU), took initiatives in 1966 which led to the establishment of its UNISIST programme. Its aims are to co-ordinate existing trends towards international co-operation in the collection, storage and dissemination of information and to act as a catalyst. Its ultimate goal is to establish 'a flexible and loosely connected network of information services based on voluntary co-operation'. A particular concern of UNISIST is to ensure co-ordination of the information activities of the United Nations organizations. The Symposium provided an opportunity for the science information community to assess the progress already made in creating links between diverse national, international, intergovernmental and non-governmental information systems and services. Papers were presented describing current developments in the national information systems of a number of countries, with special emphasis on how these developments were furthering harmonization of national information policies and facilitating interconnection with international systems. INIS and AGRIS figured prominently amongst the international systems discussed. In addition, proposals for two new international systems, to be known as DEVSIS and SPINIS, were outlined. The former will deal with development science information; the latter will cover the information on the administrative, scientific and legal aspects of science policy. There was also discussion of international co-operation in information handling within such international organizations as the CMEA, the Commission of the European Communities and OECD

  19. The World Wide Web Revisited

    Science.gov (United States)

    Owston, Ron

    2007-01-01

    Nearly a decade ago the author wrote in one of the first widely-cited academic articles, Educational Researcher, about the educational role of the web. He argued that educators must be able to demonstrate that the web (1) can increase access to learning, (2) must not result in higher costs for learning, and (3) can lead to improved learning. These…

    Predation and competition among native and invasive species are difficult to study in aquatic environments. Identification of preys from semi-digested body parts sampled from stomach contents of the predator is very challenging. Recent studies were mainly based on use of DNA extracted from stomach content to identify the prey species. This study presents the molecular evidence that reveals the predation of critically endangered Aphanius transgrediens by world-wide invasive Gambusia affinis for a better understanding of the link between the invasion and the extinction of native species in freshwater ecosystems. DNA samples were extracted from semi-digested stomach contents of the invader and short fragments of mitochondrial NADH1 gene were amplified using species-specific primers designed in this study to make identification at species level. Existence of both the prey and the predator species were also confirmed using environmental DNA extracted from water samples.

    Breast cancer patient's expectation and choice of reconstruction is increasing and patients often satisfy their information needs outside clinic time by searching the world wide web. The aim of our study was to analyse the quality of content and extent of information regarding breast reconstruction available on YouTube videos and whether this is an appropriate additional source of information for patients. A snapshot qualitative and quantitative analysis of the first 100 videos was performed after the term 'breast reconstruction' was input into the search window of the video sharing website www.youtube.com on the 1st of September 2011. Qualitative categorical analysis included patient, oncological and reconstruction factors. It was concluded that although videos uploaded onto YouTube do not provide comprehensive information, it is a useful resource that can be utilised in patient education provided comprehensive and validated videos are made available.

    The results of analytical measurements play a vital role in our daily lives. Analytical data may be the basis upon which economic, legal or environmental management decisions are made, and they are essential in international trade, environmental protection, safe transportation, law enforcement, consumer safety and the preservation of human health. As an incorrect decision can be extremely costly and detrimental, it is essential that such measurements are accurate, reliable, cost effective and defensible. In addition, measurements performed by laboratories located worldwide should yield traceable and comparable results. Proficiency testing is a method for regularly assessing the accuracy of the analytical data produced by the laboratories of particular measurements. The IAEA-CU-2006-03 world-wide proficiency test (PT) on the determination of gamma emitting radionuclides in water grass and soil is conducted by the Chemistry Unit of the IAEA's Laboratories located in Seibersdorf (Austria), which is actively involved in the production and characterization of matrix reference materials of terrestrial origin, widely used for method validation and organization of proficiency tests and intercomparison studies. The Chemistry Unit is a part of the Physics, Chemistry and Instrumentation Laboratory. This report describes the sample preparation methodology, data evaluation approach, summary evaluation of each nuclide and individual evaluation report for each laboratory

  12. Quality of drug information on the World Wide Web and strategies to improve pages with poor information quality. An intervention study on pages about sildenafil.

    The generally poor quality of health information on the world wide web (WWW) has caused preventable adverse outcomes. Quality management of information on the internet is therefore critical given its widespread use. In order to develop strategies for the safe use of drugs, we scored general and content quality of pages about sildenafil and performed an intervention to improve their quality. The internet was searched with Yahoo and AltaVista for pages about sildenafil and 303 pages were included. For assessment of content quality a score based on accuracy and completeness of essential drug information was assigned. For assessment of general quality, four criteria were evaluated and their association with high content quality was determined by multivariate logistic regression analysis. The pages were randomly allocated to either control or intervention group. Evaluation took place before, as well as 7 and 22 weeks after an intervention which consisted of two letters with individualized feedback information on the respective page which were sent electronically to the address mentioned on the page. Providing references to scientific publications or prescribing information was significantly associated with high content quality (odds ratio: 8.2, 95% CI 3.2, 20.5). The intervention had no influence on general or content quality. To prevent adverse outcomes caused by misinformation on the WWW individualized feedback to the address mentioned on the page was ineffective. It is currently probably the most straight-forward approach to inform lay persons about indicators of high information quality, i.e. the provision of references.

  13. Searching for information on the World Wide Web with a search engine: a pilot study on cognitive flexibility in younger and older users.

    2010-04-01

    This pilot study investigated the age-related differences in searching for information on the World Wide Web with a search engine. 11 older adults (6 men, 5 women; M age=59 yr., SD=2.76, range=55-65 yr.) and 12 younger adults (2 men, 10 women; M=23.7 yr., SD=1.07, range=22-25 yr.) had to conduct six searches differing in complexity, and for which a search method was or was not induced. The results showed that the younger and older participants provided with an induced search method were less flexible than the others and produced fewer new keywords. Moreover, older participants took longer than the younger adults, especially in the complex searches. The younger participants were flexible in the first request and spontaneously produced new keywords (spontaneous flexibility), whereas the older participants only produced new keywords when confronted by impasses (reactive flexibility). Aging may influence web searches, especially the nature of keywords used.

  15. Sharing individual patient and parasite-level data through the WorldWide Antimalarial Resistance Network platform: A qualitative case study [version 1; referees: 2 approved

    Directory of Open Access Journals (Sweden)

    Elizabeth Pisani

    2017-08-01

    Full Text Available Background: Increasingly, biomedical researchers are encouraged or required by research funders and journals to share their data, but there's very little guidance on how to do that equitably and usefully, especially in resource-constrained settings. We performed an in-depth case study of one data sharing pioneer: the WorldWide Antimalarial Resistance Network (WWARN. Methods: The case study included a records review, a quantitative analysis of WAARN-related publications, in-depth interviews with 47 people familiar with WWARN, and a witness seminar involving a sub-set of 11 interviewees. Results: WWARN originally aimed to collate clinical, in vitro, pharmacological and molecular data into linked, open-access databases intended to serve as a public resource to guide antimalarial drug treatment policies. Our study describes how WWARN navigated challenging institutional and academic incentive structures, alongside funders' reluctance to invest in capacity building in malaria-endemic countries, which impeded data sharing. The network increased data contributions by focusing on providing free, online tools to improve the quality and efficiency of data collection, and by inviting collaborative authorship on papers addressing policy-relevant questions that could only be answered through pooled analyses. By July 1, 2016, the database included standardised data from 103 molecular studies and 186 clinical trials, representing 135,000 individual patients. Developing the database took longer and cost more than anticipated, and efforts to increase equity for data contributors are on-going. However, analyses of the pooled data have generated new methods and influenced malaria treatment recommendations globally. Despite not achieving the initial goal of real-time surveillance, WWARN has developed strong data governance and curation tools, which are now being adapted relatively quickly for other diseases. Conclusions: To be useful, data sharing requires

    Reductions of zooplankton biomasses and grazing pressures were observed during overfishing-induced trophic cascades and concurrent oil spills at global scales. Recent phytoplankton increments followed, once Fe-, P-, and N-nutrient limitations of commensal diazotrophs and dinoflagellates were also eliminated by respective human desertification, deforestation, and eutrophication during climate changes. Si-limitation of diatoms instead ensued during these last anthropogenic perturbations of agricultural effluents and sewage loadings. Consequently, ~15% of total world-wide annual asthma trigger responses, i.e. amounting to ~45 million adjacent humans during 2004, resulted from brevetoxin and palytoxin poisons in aerosol forms of western boundary current origins. They were denoted by greater global harmful algal bloom [HAB] abundances and breathing attacks among sea-side children during prior decadal surveys of asthma prevalence, compiled here in ten paired shelf ecosystems of western and eutrophied boundary currents. Since 1965, such inferred onshore fluxes of aerosolized DOC poisons of HABs may have served as additional wind-borne organic carriers of toxic marine MeHg, phthalate, and DDT/DDE vectors, traced by radio-iodine isotopes to potentially elicit carcinomas. During these exchanges, as much as 40% of mercury poisonings may instead have been effected by inhalation of collateral HAB-carried marine neurotoxic aerosols of MeHg, not just from eating marine fish. Health impacts in some areas were additional asthma and pneumonia episodes, as well as endocrine disruptions among the same adjacent humans, with known large local rates of thyroid cancers, physician-diagnosed pulmonary problems, and ubiquitous high indices of mercury in hair, pesticides in breast milk, and phthalates in urine.

    Instructive laparoscopy videos with appropriate exposition could be ideal for initial training in laparoscopic surgery, but unfortunately there are no guidelines for annotating these videos or agreed methods to measure the educational content and the safety of the procedure presented. Aim of this study is to systematically search the World Wide Web to determine the availability of laparoscopic colorectal surgery videos and to objectively establish their potential training value. A search for laparoscopic right hemicolectomy videos was performed on the three most used English language web search engines Google.com, Bing.com, and Yahoo.com; moreover, a survey among 25 local trainees was performed to identify additional websites for inclusion. All laparoscopic right hemicolectomy videos with an English language title were included. Videos of open surgery, single incision laparoscopic surgery, robotic, and hand-assisted surgery were excluded. The safety of the demonstrated procedure was assessed with a validated competency assessment tool specifically designed for laparoscopic colorectal surgery and data on the educational content of the video were extracted. Thirty-one websites were identified and 182 surgical videos were included. One hundred and seventy-three videos (95%) detailed the year of publication; this demonstrated a significant increase in the number of videos published per year from 2009. Characteristics of the patient were rarely presented, only 10 videos (5.4%) reported operating time and only 6 videos (3.2%) reported 30-day morbidity; 34 videos (18.6%) underwent a peer-review process prior to publication. Formal case presentation, the presence of audio narration, the use of diagrams, and snapshots and a step-by-step approach are all characteristics of peer-reviewed videos but no significant difference was found in the safety of the procedure. Laparoscopic videos can be a useful adjunct to operative training. There is a large and increasing amount of

    This paper argues that existing models of urban concentrations are incomplete unless grounded in the most fundamental aspect of proximity; face-to-face contact. Face-to-face contact has four main features; it is an efficient communication technology; it can help solve incentive problems; it can facilitate socialization and learning; and it provides psychological motivation. We discuss each of these features in turn, and develop formal economic models of two of them. Face-to-face is particular...

As with contradictory propositions about homosexuality, contradiction does not undermine discourse but makes it stronger and more agile. Este artículo utiliza la teoría Queer, más concretamente la literatura sobre Bowers vs. Hardwick, para analizar los debates sobre la legislación propuesta en Quebec en relación al velo. La teoría Queer arroja luz sobre las respuestas legales al velo. Los debates parlamentarios en Quebec reconstituyen la forma de gobierno, especialmente como secular y unido. El documento pone de relieve el carácter contradictorio e inestable de cuatro binarios: texto legislativo frente a las prácticas sociales; legislación frente a estado; mayoría versus minoría; y conocible frente a incognoscible. Al igual que con las proposiciones contradictorias acerca de la homosexualidad, la contradicción no socava el discurso, sino que lo hace más fuerte y más ágil.

    The concentration of ions in the electrolyte solution in lithium ion batteries changes during operation, reflecting the resistance to ion migration and the positions of diffusion barriers. The change causes various negative effects on the performance of batteries. Thus, it is important to elucidate how the concentration changes during operation. In this work, the concentration change of ions in the electrolyte solution in deep narrow spaces in a realistic battery was studied by in situ ultrafine microprobe Raman spectroscopy. Graphite composite and LiCoO 2 composite electrodes, which are the most commonly used electrodes in practical batteries, were placed facing each other and their distance was set to 80 μm, which is close to the distance between electrodes in practical batteries. After repeated charge/discharge cycles, the concentration of ions increased and decreased greatly during charging and discharging, respectively. The maximum concentration was more than three-times higher than the minimum concentration. The rate of changes in concentration increased almost linearly with increase in current density. The results have important implications about concentration changes of ions occurring in practical batteries.

    cyclopolymerize, but only in DMF at 122°C and at a 10:1 solvent:monomer ratio. A multimedia educational program called The Macrogalleria dealing with polymer science was created and distributed by the world wide web and on cd-rom. The site is made in the form of a virtual shopping mall in which each store is a lesson on some aspect of polymer science. The lessons are written in informal language to make the material more accessible. Also, the lessons are connected by hypertext links in a nonlinear fashion to allow students to create their own pathways through the material. The Macrogalleria has been very successful, being used by educational institutions to incorporate polymer science into the undergraduate chemistry curriculum, and by many industrial users as well. It has received numerous awards as well.

  11. Canopy position affects photosynthetic adjustments to long-term elevated CO{sub 2} concentration (FACE) in aging needles in a mature Pinus taeda forest

    Crous, K. Y.; Ellsworth, D. S. [University of Michigan, School of Natural Resources and Environment, Ann Arbor, MI (United States)

    2004-09-01

    Results of an assessment of the long-term effects of exposure to elevated carbon dioxide in free-air enrichment (FACE) on two age classes of pine needles in the upper and lower canopy of a pine forest in North Carolina are discussed. The observations were made during the second through sixth year of exposure. A significant response was observed in 60 per cent of all age classes and canopy locations. Evidence of concurrent down-regulation of Rubisco and electron transport capacity in upper canopy sunlit leaves was noted beyond the sixth year. No such effect was seen in the lower canopy. Carboxylation capacity and electron transport capacity in the upper canopy was down-regulated by 17-20 per cent in one year-old needles, but this was significant across sampling years only for electron transport capacity. It is suggested that a reduction in photosynthetic capacity in aging conifer needles at the canopy top may have significant consequences for canopy carbon balance and global carbon sinks because a major proportion of the annual carbon balance of these conifers is contributed by one-year old sunlit needles. 45 refs., 3 tabs., 4 figs.

  12. Constraining dark matter halo profiles and galaxy formation models using spiral arm morphology. II. Dark and stellar mass concentrations for 13 nearby face-on galaxies

    International Nuclear Information System (INIS)

    Seigar, Marc S.; Davis, Benjamin L.; Berrier, Joel; Kennefick, Daniel

    2014-01-01

    We investigate the use of spiral arm pitch angles as a probe of disk galaxy mass profiles. We confirm our previous result that spiral arm pitch angles (P) are well correlated with the rate of shear (S) in disk galaxy rotation curves. We use this correlation to argue that imaging data alone can provide a powerful probe of galactic mass distributions out to large look-back times. We then use a sample of 13 galaxies, with Spitzer 3.6 μm imaging data and observed Hα rotation curves, to demonstrate how an inferred shear rate coupled with a bulge-disk decomposition model and a Tully-Fisher-derived velocity normalization can be used to place constraints on a galaxy's baryon fraction and dark matter halo profile. Finally, we show that there appears to be a trend (albeit a weak correlation) between spiral arm pitch angle and halo concentration. We discuss implications for the suggested link between supermassive black hole (SMBH) mass and dark halo concentration, using pitch angle as a proxy for SMBH mass.

    Coral-Alvarado, Paola; Pardo, Aryce L; Castaño-Rodriguez, Natalia; Rojas-Villarraga, Adriana; Anaya, Juan-Manuel

    2009-07-01

    The objective of this study was to analyze epidemiological tendencies of systemic sclerosis (SSc) around the world in order to identify possible local variations in the presentation and occurrence of the disease. A systematic review of the literature was performed through electronic databases using the keywords "Systemic Sclerosis" and "Clinical Characteristics." Out of a total of 167 articles, 41 were included in the analysis. Significant differences in the mean age at the time of diagnosis, subsets of SSc, clinical characteristics, and presence of antibodies were found between different regions of the word. Because variations in both additive and nonadditive genetic factors and the environmental variance are specific to the investigated population, ethnicity and geography are important characteristics to be considered in the study of SSc and other autoimmune diseases.

  16. Network dynamics: The World Wide Web

    Science.gov (United States)

    Adamic, Lada Ariana

    Despite its rapidly growing and dynamic nature, the Web displays a number of strong regularities which can be understood by drawing on methods of statistical physics. This thesis finds power-law distributions in website sizes, traffic, and links, and more importantly, develops a stochastic theory which explains them. Power-law link distributions are shown to lead to network characteristics which are especially suitable for scalable localized search. It is also demonstrated that the Web is a "small world": to reach one site from any other takes an average of only 4 hops, while most related sites cluster together. Additional dynamical properties of the Web graph are extracted from diffusion processes.

    Spearman, M. L.

    1978-01-01

    This paper attempts to put in perspective the development of missiles from early history to present time. The influence of World War II in accelerating the development of guided missiles, particularly through German scientists, is discussed. The dispersion of German scientists to other countries and the coupling of their work with native talent to develop guided missiles is traced. Particular emphasis is placed on the evolution of the missile in the U.S. and the U.S.S.R. Since the Soviets possess what is probably the world's most complete array of dedicated missile system types, their known inventory is reviewed in some detail.

  3. [Current tuberculosis mortality world-wide].

    Science.gov (United States)

    Haefliger, E; Rieder, H L

    1992-04-21

    The mortality rate still is an important index for assessment of tuberculosis. Statistical records are kept on the mortality rate on a worldwide basis--more than in the case of other tuberculosis parameters. They allow us to make valuable comparisons. They are also useful because the mortality is closely related to the morbidity. The present thesis is based on comparative figures from the 1989 volume of the WHO Health Statistics Annual. Various countries have been specially selected by the publisher--and subsequently also by us--for sake of clarity. The figures vary strongly within these countries, which was to be expected. The mortality rate varies in Europe (for each 100,000 residents) e.g. from 0.2 in the Netherlands to 8.15 in the Soviet Union. In the Americas the rates vary from 0.4 for Canada to 12.9 for Ecuador. In the Western Pacific region the mortality rates vary from 0.35 for Australia to 14.65 for China. On a worldwide basis, the share of deaths from tuberculosis among all causes of death varies from 0.02% in the Netherlands to 2.10% in the Republic of Korea. The relation of tuberculosis deaths with regard to sexes in Switzerland: 75.7% men, 24.3% women, which is more or less the European average. The lower the mortality rate for tuberculosis are, the lower the difference between the sexes appears to be. Similar facts are found with regard to the distribution of tuberculosis deaths according to age groups: the lower the tuberculosis rate, the more tuberculosis is found in older age groups. The tuberculosis deaths are percentage-wise similarly distributed to the respiratory organs and the other tuberculosis forms.(ABSTRACT TRUNCATED AT 250 WORDS)

    1998-01-01

    Through their operating records, CANDU reactors have established themselves as a successful and cost-effective source of electricity in Canada and abroad. They have proven to be safe, reliable and economical. A variety of factors have contributed to the enviable CANDU record, such as a sound design based on proven principles supported by effective development programs, along with dedicated plant owners committed to excellence in safely maintaining and operating their plants. Atomic Energy of Canada Limited (AECL), the CANDU designer, has continuously maintained a close relationship with owners/operators of the plants in Canada, Argentina, Romania and South Korea. AECL and the plant operators have all benefited from this strengthening relationship by sharing experience and information. CANDU plant operators have been required to respond decisively to the economic realities of downward cost pressures and deregulation. Operating, Maintenance and Administration (OM and A) costs are being given a new focus as plant owners review each cost element to improve the economic returns from their investments. Amongst the three main OM and A constituents, plant maintenance costs are the most variable and have the largest influence on effective plant operations. The correlation between effective plant maintenance and high capacity factors shows clearly the importance of proactive maintenance planning to reduce the frequency and duration of forced plant outages and their negative impacts on plant economics. This paper describes the management processes and organizational structures m AECL that support plant operations and maintenance in operating CANDU plants with cost effective products and services.

  5. Natural background radiation exposures world-wide

    International Nuclear Information System (INIS)

    Bennett, B.G.

    1993-01-01

    The average radiation dose to the world's population from natural radiation sources has been assessed by UNSCEAR to be 2.4 mSv per year. The components of this exposure, methods of evaluation and, in particular, the variations in the natural background levels are presented in this paper. Exposures to cosmic radiation range from 0.26 mSv per year at sea level to 20 times more at an altitude of 6000 m. Exposures to cosmogenic radionuclides ( 3 H, 14 C) are relatively insignificant and little variable. The terrestrial radionuclides 40 K, 238 U, and 232 Th and the decay products of the latter two constitute the remainder of the natural radiation exposure. Wide variations in exposure occur for these components, particularly for radon and its decay products, which can accumulate to relatively high levels indoors. Unusually high exposures to uranium and thorium series radionuclides characterize the high natural background areas which occur in several localized regions in the world. Extreme values in natural radiation exposures have been estimated to range up to 100 times the average values. (author). 15 refs, 3 tabs

    2015-01-01

    It has been previously established that extraverts who are skilled at interpersonal interaction perform significantly better than introverts on a face-specific recognition memory task. In our experiment we further investigate the relationship between extraversion and face recognition, focusing on famous face recognition and face matching. Results indicate that more extraverted individuals perform significantly better on an upright famous face recognition task and show significantly larger face inversion effects. However, our results did not find an effect of extraversion on face matching or inverted famous face recognition.

Die Messung der virtuellen Kampfkraft erfolgt auf Basis von drei Faktoren: Offensivkraft, Defensivfähigkeit und die Abhängigkeit vom Internet. Die USA verfügen als "Supermacht" zwar über die größte virtuelle Offensivkraft, gleichzeitig steht die Nation Cyberangriffen sehr verwundbar gegenüber. Dagegen sind in Nordkorea kaum Systeme vom Internet abhängig. Obwohl die offensiven Netzkriegskapazitäten Nordkoreas verhältnismäßig gering sind, präsentiert sich die virtuelle Kampfkraft des nordkoreanischen Regimes in Bestform. Die Verwundbarkeit ziviler Systeme, insbesondere der Energieversorgung, muss in direkter Korrelation mit deren Anknüpfung an das Internet betrachtet werden. The more broadly connected a country’s infrastructure and energy distribution, the greater its vulnerability in the event of a cyber war. Measuring this virtual fighting power is based on three factors: offensive and defensive strength, as well as dependency on the Internet. As a superpower, the USA has the greatest virtual offensive strength available. At the same time, the nation is most susceptible to cyber attacks and therefore most vulnerable. By contrast, North Korea’s offensive cyber fighting power is relatively small, but its overall cyber war capabilities are cutting-edge. The vulnerability of civil systems, especially power supply, must be viewed in direct correlation to their connection to the Internet.

  3. Familiar face + novel face = familiar face? Representational bias in the perception of morphed faces in chimpanzees

    Directory of Open Access Journals (Sweden)

    Yoshi-Taka Matsuda

    2016-08-01

    Full Text Available Highly social animals possess a well-developed ability to distinguish the faces of familiar from novel conspecifics to induce distinct behaviors for maintaining society. However, the behaviors of animals when they encounter ambiguous faces of familiar yet novel conspecifics, e.g., strangers with faces resembling known individuals, have not been well characterised. Using a morphing technique and preferential-looking paradigm, we address this question via the chimpanzee’s facial–recognition abilities. We presented eight subjects with three types of stimuli: (1 familiar faces, (2 novel faces and (3 intermediate morphed faces that were 50% familiar and 50% novel faces of conspecifics. We found that chimpanzees spent more time looking at novel faces and scanned novel faces more extensively than familiar or intermediate faces. Interestingly, chimpanzees looked at intermediate faces in a manner similar to familiar faces with regards to the fixation duration, fixation count, and saccade length for facial scanning, even though the participant was encountering the intermediate faces for the first time. We excluded the possibility that subjects merely detected and avoided traces of morphing in the intermediate faces. These findings suggest a bias for a feeling-of-familiarity that chimpanzees perceive familiarity with an intermediate face by detecting traces of a known individual, as 50% alternation is sufficient to perceive familiarity.

    Recently, as a measure to reduce an outage duration in nuclear power plants (NPPs), a four-face fuel visual inspection system (4-FFVIS) built in 4 cameras was introduced by Ahlberg Electronics, Sweden. The 4- FFVIS is used to inspect the external appearance of irradiated fuel assemblies in order to confirm their integrity against mechanical defects and foreign materials. Until now, however, a typical one-face fuel inspection system(1-FFVIS) has been world-widely utilized in NPPs. The 1-FFVIS requires four turns with 90 degree to inspect every face of the fuel assembly, causing a relatively long inspecting time. But the 4- FFVIS allow us to inspect every face of the fuel assembly at the same time. The inspection time with the 4-FFVIS may be less than two minutes per fuel assembly, whereas that with the 1-FFVIS is about six minutes per fuel assembly. In viewpoint of this merit, the 4-FFVIS is expected to be world-widely used in the near future. In this paper, the technical requirements necessary to develop the 4-FFVIS as well as some improvements to complement the current 4-FFVIS are described

    Editing faces in movies is of interest in the special effects industry. We aim at producing effects such as the addition of accessories interacting correctly with the face or replacing the face of a stuntman with the face of the main actor. The system introduced in this thesis is based on a 3D generative face model. Using a 3D model makes it possible to edit the face in the semantic space of pose, expression, and identity instead of pixel space, and due to its 3D nature allows...

  6. Series 'Facing Radiation'. 2 Facing radiation is facing residents

    The series is to report how general people, who are not at all radiological experts, have faced and understood the problems and tasks of radiation given by the Fukushima Daiichi Nuclear Power Plant Accident (Mar. 2011). The section 2 is reported by an officer of Date City, which localizes at 60 km northern west of the Plant, borders on Iitate Village of Fukushima prefecture, and is indicated as the important area of contamination search (IACS), which the reporter has been conducted for as responsible personnel. In July 2011, the ambient dose was as high as 3.0-3.5 mc-Sv/h and the tentative storage place of contaminated materials was decided by own initiative of residents of a small community, from which the real decontamination started in the City. The target dose after decontamination was defined to be 1.0 mc-Sv/h: however, 28/32 IACS municipalities in the prefecture had not defined the target although they had worked for 2 years after the Accident for their areas exceeding the standard 0.23 mc-Sv/h. At the moment of decontamination of the reporter's own house, he noticed that resident's concerns had directed toward its work itself, not toward the target dose, and wondered if these figures had obstructed to correctly face the radiation. At present that about 2.5 years have passed since the Accident, all of Date citizens have personal accumulated glass dosimeters for seeing the effective external dose and it seems that their dose will not exceed 1 mSv/y if the ambient dose estimated is 0.3-5 mc-Sv/h. Media run to popularity not to face radiation, experts tend to hesitate to face media and residents, and radiation dose will be hardly reduced to zero, despite that correct understanding of radiation is a shorter way for residents' own ease: facing radiation is facing residents.

    Face transplantation is the innovative application of microsurgery and immunology to restore appearance and function to those with severe facial disfigurements. Our group aims to establish a multidisciplinary education program that can facilitate informed consent and build a strong knowledge base in patients to enhance adherence to medication regimes, recovery, and quality of life. We analyzed handbooks from our institution's solid organ transplant programs to identify topics applicable to face transplant patients. The team identified unique features of face transplantation that warrant comprehensive patient education. We created a 181-page handbook to provide subjects interested in pursuing transplantation with a written source of information on the process and team members and to address concerns they may have. While the handbook covers a wide range of topics, it is easy to understand and visually appealing. Face transplantation has many unique aspects that must be relayed to the patients pursuing this novel therapy. Since candidates lack third-party support groups and programs, the transplant team must provide an extensive educational component to enhance this complex process. As face transplantation continues to develop, programs must create sound education programs that address patients' needs and concerns to facilitate optimal care.

  12. Learning discriminant face descriptor.

    Science.gov (United States)

    Lei, Zhen; Pietikäinen, Matti; Li, Stan Z

    2014-02-01

    Local feature descriptor is an important module for face recognition and those like Gabor and local binary patterns (LBP) have proven effective face descriptors. Traditionally, the form of such local descriptors is predefined in a handcrafted way. In this paper, we propose a method to learn a discriminant face descriptor (DFD) in a data-driven way. The idea is to learn the most discriminant local features that minimize the difference of the features between images of the same person and maximize that between images from different people. In particular, we propose to enhance the discriminative ability of face representation in three aspects. First, the discriminant image filters are learned. Second, the optimal neighborhood sampling strategy is soft determined. Third, the dominant patterns are statistically constructed. Discriminative learning is incorporated to extract effective and robust features. We further apply the proposed method to the heterogeneous (cross-modality) face recognition problem and learn DFD in a coupled way (coupled DFD or C-DFD) to reduce the gap between features of heterogeneous face images to improve the performance of this challenging problem. Extensive experiments on FERET, CAS-PEAL-R1, LFW, and HFB face databases validate the effectiveness of the proposed DFD learning on both homogeneous and heterogeneous face recognition problems. The DFD improves POEM and LQP by about 4.5 percent on LFW database and the C-DFD enhances the heterogeneous face recognition performance of LBP by over 25 percent.

  14. Face inversion increases attractiveness.

    Leder, Helmut; Goller, Juergen; Forster, Michael; Schlageter, Lena; Paul, Matthew A

    2017-07-01

    Assessing facial attractiveness is a ubiquitous, inherent, and hard-wired phenomenon in everyday interactions. As such, it has highly adapted to the default way that faces are typically processed: viewing faces in upright orientation. By inverting faces, we can disrupt this default mode, and study how facial attractiveness is assessed. Faces, rotated at 90 (tilting to either side) and 180°, were rated on attractiveness and distinctiveness scales. For both orientations, we found that faces were rated more attractive and less distinctive than upright faces. Importantly, these effects were more pronounced for faces rated low in upright orientation, and smaller for highly attractive faces. In other words, the less attractive a face was, the more it gained in attractiveness by inversion or rotation. Based on these findings, we argue that facial attractiveness assessments might not rely on the presence of attractive facial characteristics, but on the absence of distinctive, unattractive characteristics. These unattractive characteristics are potentially weighed against an individual, attractive prototype in assessing facial attractiveness. Copyright © 2017 The Authors. Published by Elsevier B.V.

    Full Text Available Visual images that are not faces are sometimes perceived as faces (the pareidolia phenomenon. While the pareidolia phenomenon provides people with a strong impression that a face is present, it is unclear how deeply pareidolia faces are processed as faces. In the present study, we examined whether a shift in spatial attention would be produced by gaze cueing of face-like objects. A robust cueing effect was observed when the face-like objects were perceived as faces. The magnitude of the cueing effect was comparable between the face-like objects and a cartoon face. However, the cueing effect was eliminated when the observer did not perceive the objects as faces. These results demonstrated that pareidolia faces do more than give the impression of the presence of faces; indeed, they trigger an additional face-specific attentional process.

    Turn around time/cycle time is a key success criterion in the semiconductor photomask business. Therefore, global mask suppliers typically allocate work loads based on fab capability and utilization capacity. From a logistical point of view, the manufacturing location of a photomask should be transparent to the customer (mask user). Matching capability of production equipment and especially metrology tools is considered a key enabler to guarantee cross site manufacturing flexibility. Toppan, with manufacturing sites in eight countries worldwide, has an on-going program to match the registration metrology systems of all its production sites. This allows for manufacturing flexibility and risk mitigation.In cooperation with Vistec Semiconductor Systems, Toppan has recently completed a program to match the Vistec LMS IPRO systems at all production sites worldwide. Vistec has developed a new software feature which allows for significantly improved matching of LMS IPRO(x) registration metrology tools of various generations. We will report on the results of the global matching campaign of several of the leading Toppan sites.

    1989-04-01

    This article discusses the need for family planning (FP) as part of the development process, applauds its successes and rallies continued momentum of the FP movement. 500,000 women die each year from pregnancy- or labor-related conditions, and 10s of millions of women suffer pregnancy-related illnesses and impairments that undermine their social and economic productivity. Moreover, the 4 major factors that lead to high-risk pregnancies, namely, becoming pregnant before the age of 20, after the age of 35, after 4 or more pregnancies, and 2 years after an earlier pregnancy, all reveal the need for FP. These tragedies could be avoided by assuring better nutrition, primary health care for all, good antenatal attention and proper facilities and help in childbirth, access to good obstetric care in emergency situations, and universally available FP services. FP organizations must empower women with the knowledge of FP and the means to put it into practice. Developing countries, such as China, India, Indonesia, Thailand and Mexico, in addition to affluent industrialized countries have made strides in FP with the help of such organizations as the International Planned Parenthood Federation (IPPF). IPPF has helped to motivate large numbers of men and women to determine their ideal family size. It has provided the means for them to reach such goals and has ensured that acceptance of FP has been on a voluntary basis. IPPF has also advised and cajoled governments into becoming involved in FP. In the future, national strategies must produce the building blocks for better policies to help women become more responsible for their lives. The education of women will be vital to achieving this objective as well as other aspects of development.

    WIRED ( http://wired.cern.ch/) is a framework, written in Java, to build High Energy Physics event displays that can be used across the network. To guarantee portability across all platforms, WIRED is implemented in the Java language and uses the Swing user interface component set. It can be used as a stand-alone application or as an applet inside a WWW browser. The graphical user interface allows for multiple views and for multiple controls acting on those views. A detector tree control is available to toggle the visibility of parts of the events and detector geometry. XML (Extensible Markup Language), RMI (Remote Method Invocation) and CORBA loaders can be used to load event data as well as geometry data, and to connect to FORTRAN, C, C++ and Java reconstruction programs. Non-linear and non-Cartesian projections (e.g., fisheye, ρ- φ, ρ- Z, φ- Z) provide special views to get a better understanding of events. A special Java interpreter allows physicists to write small scripts to interact with their data and its display. WIRED has grown to be a framework in use and under development in several HEP experiments (ATLAS, CHORUS, DELPHI, LHCb, BaBar, D0 and ZEUS). WIRED event displays have also proven to be useful to explain High Energy Physics to the general public. Both CERN, in its traveling exhibition and MicroCosm, and RAL, during its open days, have displays set up.

    1998-10-01

    Interactive image processing is a proven technique for analyzing industrial vision applications and building prototype systems. Several of the previous implementations have used dedicated hardware to perform the image processing, with a top layer of software providing a convenient user interface. More recently, self-contained software packages have been devised and these run on a standard computer. The advent of the Java programming language has made it possible to write platform-independent software, operating over the Internet, or a company-wide Intranet. Thus, there arises the possibility of designing at least some shop-floor inspection/control systems, without the vision engineer ever entering the factories where they will be used. It successful, this project will have a major impact on the productivity of vision systems designers.

    Raspberry Shake was conceived as an inexpensive plug-and-play solution to satisfy the need for universal, quick and accurate earthquake detections. First launched on Kickstarter's crowdfunding platform in July of 2016, the Raspberry Shake project was funded within hours of the launch date and, by the end of the campaign, reached more than 1000% of its initial funding goal. This demonstrated for the first time that there exists a strong interest among Makers, Hobbyists and Do It Yourselfers for personal seismographs. From here, a citizen scientist network was created and it has steadily been growing. The Raspberry Shake network is currently being used in conjunction with publicly available broadband data from the GSN and other state-run seismic networks available through the IRIS, Geoscope and GEOFON data centers to detect and locate earthquakes large and small around the globe. Raspberry Shake looks well positioned to improve local monitoring of earthquakes on a global scale, deepen community's understanding of earthquakes, and serve as a formidable teaching tool. We present the main results of the project, the current state of the network, and the new Raspberry Shake models that are being built.

    A software program that searches and browses mission data emulates a Web browser, containing standard meta - phors for Web browsing. By taking advantage of back-end URLs, users may save and share search states. Also, since a Web interface is familiar to users, training time is reduced. Familiar back and forward buttons move through a local search history. A refresh/reload button regenerates a query, and loads in any new data. URLs can be constructed to save search results. Adding context to the current search is also handled through a familiar Web metaphor. The query is constructed by clicking on hyperlinks that represent new components to the search query. The selection of a link appears to the user as a page change; the choice of links changes to represent the updated search and the results are filtered by the new criteria. Selecting a navigation link changes the current query and also the URL that is associated with it. The back button can be used to return to the previous search state. This software is part of the MSLICE release, which was written in Java. It will run on any current Windows, Macintosh, or Linux system.

    International Observe the Moon Night (InOMN) is an annual worldwide public event that encourages observation, appreciation, and understanding of our Moon and its connection to NASA planetary science and exploration. Everyone on Earth is invited to join the celebration by hosting or attending an InOMN event - and uniting on one day each year to look at and learn about the Moon together. Events are hosted by a variety of institutions including astronomy clubs, observatories, schools, and universities, museums, planetaria, schools, universities, observatories, parks, private businesses and private homes. Events hosts are supported with event flyers, information sheets, Moon maps for observing, activities to use during events, presentations, certificates of participation, and evaluation materials to be used by hosts. 2016 is the seventh year of worldwide participation in InOMN which will be held on October 8th. In the last six years, over 3,000 events were registered worldwide from almost 100 different countries and almost all 50 states and the District of Columbia in the United States. Evaluation of InOMN is conducted by an external evaluation group and includes analysis of event registrations, facilitator surveys, and visitor surveys. Evaluation results demonstrate that InOMN events are successful in raising visitors' awareness of lunar science and exploration, providing audiences with information about lunar science and exploration, and inspiring visitors to want to learn more about the Moon. Additionally, preliminary analysis of social media has shown that there is a virtual network of individuals connecting about InOMN. A large fraction of events have been held by institutions for more than one year showing sustained interest in participation. During this presentation, we will present data for all seven years of InOMN including lessons learned through supporting and evaluating a worldwide event. InOMN is sponsored by NASA's Lunar Reconnaissance Orbiter, NASA's Solar System Exploration Research Virtual Institute (SSERVI), and the Lunar and Planetary Institute.

    The reliable and adequate supply of energy, especially electricity, is necessary not only for economic development but to enhance the quality of life. Nuclear power is a proven technology which already supplies about 17% of the world''s electricity generation. In 1995, seven countries produce more than 40% of their electricity from nuclear power plants: Lithuanian, France, Belgium, Sweden, Bulgaria, Slovak and Hungary. It is quite clear that many countries are heavily reliant on nuclear power and are well beyond the point where nuclear power could be replaced by some other source, so, nuclear power remains one of the few technologically proven, economically promising and environmentally benign energy sources. An important factor in the continued development of nuclear power is the extent to which nuclear generated electricity remains economically competitive. Factors such as plant availability, standardisation of systems, components and equipment, as well as the cost of equipment to meet safety and environmental regulations play also an important role in determining the relative competitiveness of nuclear power plants. Many operating organizations have already impressive results in the reduction of plant unavailability. The number of nuclear power plants currently operating with annual availability factor exceeding 85% is increasing. Good performance of some operators should establish performance targets for operators everywhere. The International Atomic Energy Agency (IAEA) has the only international and almost complete information system, the Power Reactor Information System (PRIS) with nuclear power plant status and performance data. This paper presents the current status of nuclear power plants, according to information contained in the IAEA. It discusses the plant performance indicators available in PRIS and the improvement trend in the performance of nuclear power plants based on these indicators. It also presents the future trends of nuclear power focusing in the major nuclear power producing countries. (author)

    (Abstract only) Among the 1000 known cataclysmic variables, only one appears to belong to the "Galactic halo"-the Population II stars. We report round-the-world photometry of this star (OV Boo) during March-April 2017, when it staged its first certified dwarf-nova outburst. The star is remarkable for its short binary period (66 minutes), high proper motion, metal-poor composition, substellar secondary, sharp white-dwarf eclipses, and nonradial pulsations. Something for everybody - and it even had the good manners to erupt in northern springtime, when it transits near local midnight. Move over, SS Cyg and WZ Sge; there's a new celebrity in town!

  1. Quality of breast cancer sites on the World Wide Web.

    Hoffman-Goetz, L; Clarke, J N

    2000-01-01

    The Internet is a powerful tool for accessing information about complex health topics. The purpose of this study was to evaluate breast cancer Internet sites using published criteria about website structure. Two searches were undertaken (November 1998 and June 1999) using the Yahoo search engine, providing a sample of 136 unique addresses. The results showed 1) owner's credentials were identified in 31.6% of sites, 2) financial charges were stated in 10.3% of sites, 3) less than 14.0% identified site creation date, 4) 33.1% identified content posting update, 5) 30.1% identified information sources, and 6) just under 88% of sites provided e-mail interactivity. The results indicate variability in breast cancer Internet sites with respect to framework criteria of accountability. We suggest that websites that lack fundamental indicators (such as dating and sources) do not provide the user with fundamental information that could enable informed decision making about site quality.

    It is easy to require the widely discussed termination of nuclear energy application, but it is hardly possible to realise it, unless one is prepared to accept enormous economic and ecological problems. The article investigates, whether the other energy carriers or energy saving methods, respectively, would be in a position to replace the nuclear energy. Thereby the aspects of securing the supply and its economy are of considerable importance. The author describes furthermore the effects of terminating nuclear energy on the growing world population and the economy of trading countries. Ecological problems that may also be aggravated are dealt with, too. (orig.) [de

  3. Digital libraries and World Wide Web sites and page persistence.

    Directory of Open Access Journals (Sweden)

    Wallace Koehler

    1999-01-01

    Full Text Available Web pages and Web sites, some argue, can either be collected as elements of digital or hybrid libraries, or, as others would have it, the WWW is itself a library. We begin with the assumption that Web pages and Web sites can be collected and categorized. The paper explores the proposition that the WWW constitutes a library. We conclude that the Web is not a digital library. However, its component parts can be aggregated and included as parts of digital library collections. These, in turn, can be incorporated into "hybrid libraries." These are libraries with both traditional and digital collections. Material on the Web can be organized and managed. Native documents can be collected in situ, disseminated, distributed, catalogueed, indexed, controlled, in traditional library fashion. The Web therefore is not a library, but material for library collections is selected from the Web. That said, the Web and its component parts are dynamic. Web documents undergo two kinds of change. The first type, the type addressed in this paper, is "persistence" or the existence or disappearance of Web pages and sites, or in a word the lifecycle of Web documents. "Intermittence" is a variant of persistence, and is defined as the disappearance but reappearance of Web documents. At any given time, about five percent of Web pages are intermittent, which is to say they are gone but will return. Over time a Web collection erodes. Based on a 120-week longitudinal study of a sample of Web documents, it appears that the half-life of a Web page is somewhat less than two years and the half-life of a Web site is somewhat more than two years. That is to say, an unweeded Web document collection created two years ago would contain the same number of URLs, but only half of those URLs point to content. The second type of change Web documents experience is change in Web page or Web site content. Again based on the Web document samples, very nearly all Web pages and sites undergo some form of content within the period of a year. Some change content very rapidly while others do so infrequently (Koehler, 1999a. This paper examines how Web documents can be efficiently and effectively incorporated into library collections. This paper focuses on Web document lifecycles: persistence, attrition, and intermittence. While the frequency of content change has been reported (Koehler, 1999a, the degree to which those changes effect meaning and therefore the integrity of bibliographic representation is yet not fully understood. The dynamics of change sets Web libraries apart from the traditional library as well as many digital libraries. This paper seeks then to further our understanding of the Web page and Web site lifecycle. These patterns challenge the integrity and the usefulness of libraries with Web content. However, if these dynamics are understood, they can be controlled for or managed.

  4. Application of a World Wide Web technology to environmental remediation

    2000-01-01

    As part of the Formerly Utilized Site Remedial Action Program (FUSRAP), the United States Army Corps of Engineers (USACE), Buffalo District, is responsible for overseeing the remediation of several sites within its jurisdiction. FUSRAP sites are largely privately held facilities that were contaminated by activities associated with the nuclear weapons program in the 1940s, 50s, and 60s. The presence of soils and structures contaminated with low levels of radionuclides is a common problem at these sites. Typically, contaminated materials must be disposed of off-site at considerable expense (up to several hundred dollars per cubic yard of waste material). FUSRAP is on an aggressive schedule, with most sites scheduled for close-out in the next couple of years. Among the multitude of tasks involved in a typical remediation project is the need to inform and coordinate with active stakeholder communities, including local, state, and federal regulators

    2013-04-01

    Health care practitioners have increasingly used the Internet to obtain health and medication information. The vast number of Internet Web sites providing such information and concerns with their reliability makes it essential for users to carefully select and evaluate Web sites prior to use. To this end, this article reviews the general principles to consider in this process. Moreover, as cost may limit access to subscription-based health and medication information resources with established reputability, freely accessible online resources that may serve as an invaluable addition to one's reference collection are highlighted. These include government- and organization-sponsored resources (eg, US Food and Drug Administration Web site and the American Society of Health-System Pharmacists' Drug Shortage Resource Center Web site, respectively) as well as commercial Web sites (eg, Medscape, Google Scholar). Familiarity with such online resources can assist health care professionals in their ability to efficiently navigate the Web and may potentially expedite the information gathering and decision-making process, thereby improving patient care.

    1996-01-01

    The tilt rotor aircraft holds great promise for improving air travel in the future. It's benefits include vertical take off and landing combined with airspeeds comparable to propeller driven aircraft. However, the noise from a tilt rotor during approach to a landing is potentially a significant barrier to widespread acceptance of these aircraft. This approach noise is primarily caused by Blade Vortex Interactions (BVI), which are created when the blade passes near or through the vortex trailed by preceding blades. The XV- 15 Aeroacoustic test will measure the noise from a tilt rotor during descent conditions and demonstrate several possible techniques to reduce the noise. The XV- 15 Aeroacoustic test at NASA Ames Research Center will measure acoustics and performance for a full-scale XV-15 rotor. A single XV-15 rotor will be mounted on the Ames Rotor Test Apparatus (RTA) in the 80- by 120-Foot Wind Tunnel. The test will be conducted in helicopter mode with forward flight speeds up to 100 knots and tip path plane angles up to +/- 15 degrees. These operating conditions correspond to a wide range of tilt rotor descent and transition to forward flight cases. Rotor performance measurements will be made with the RTA rotor balance, while acoustic measurements will be made using an acoustic traverse and four fixed microphones. The acoustic traverse will provide limited directionality measurements on the advancing side of the rotor, where BVI noise is expected to be the highest. Baseline acoustics and performance measurements for the three-bladed rotor will be obtained over the entire test envelope. Acoustic measurements will also be obtained for correlation with the XV-15 aircraft Inflight Rotor Aeroacoustic Program (IRAP) recently conducted by Ames. Several techniques will be studied in an attempt to reduce the highest measured BVI noise conditions. The first of these techniques will use sub-wings mounted on the blade tips. These subwings are expected to alter the size, strength, and location of the tip vortex, therefore changing the BVI acoustics of the rotor. The subwings are approximately 20% of the blade chord and increase the rotor radius by about 3 percent. Four different subwing configurations will be tested, including square tipped subwings with different angles of incidence. The ability of active controls to reduce BVI acoustics will also be assessed. The dynamic control system of the RTA will be used to implement open- and closed-loop active control techniques, including individual blade control. Open-loop testing will be conducted using a personal computer based, automated, real-time data acquisition system. This system features combined automated output of open loop control signals and automated data acquisition of the resulting test data. A final technique to alter the noise of the rotor will be examined. This will involve changing the number of blades from three to four. A four-bladed rotor hub has been fabricated on which the XV-15 blades will be mounted. While the solidity of the rotor will increase, much useful information can be gained by examining the changes in the thrust and RPM with four blades.

    New web-based technologies provide an excellent opportunity for sharing and accessing information and using web as a platform for interaction and collaboration. Although several specialized tools are available for analyzing DNA sequence information, conventional web-based tools have not been utilized for bioinformatics applications. We have developed a novel algorithm and implemented it for searching species-specific genomic sequences, DNA barcodes, by using popular web-based methods such as Google. We developed an alignment independent character based algorithm based on dividing a sequence library (DNA barcodes) and query sequence to words. The actual search is conducted by conventional search tools such as freely available Google Desktop Search. We implemented our algorithm in two exemplar packages. We developed pre and post-processing software to provide customized input and output services, respectively. Our analysis of all publicly available DNA barcode sequences shows a high accuracy as well as rapid results. Our method makes use of conventional web-based technologies for specialized genetic data. It provides a robust and efficient solution for sequence search on the web. The integration of our search method for large-scale sequence libraries such as DNA barcodes provides an excellent web-based tool for accessing this information and linking it to other available categories of information on the web.

    Oral contraceptive pills are safe, effective, and available without a prescription in most countries. Despite support from the American Congress of Obstetricians and Gynecologists to provide oral contraceptives as an over-the-counter medication, US women are still required to have a prescription to obtain them. Use of online applications and the Internet has made most things easier to obtain in our society and this includes contraceptive methods. Several online ventures are now underway to enable US women to obtain oral contraceptives without visiting a medical provider's office. Women's health care professionals should encourage these novel approaches, as they will improve contraceptive access. As US women experiment with innovative health care models, providers will need to lead, follow, or be left behind. Copyright © 2015 Elsevier Inc. All rights reserved.

  1. The future of nuclear power: A world-wide perspective

    Science.gov (United States)

    Aktar, Ismail

    This study analyzes the future of commercial nuclear electric generation worldwide using the Environmental Kuznets Curve (EKC) concept. The Tobit panel data estimation technique is applied to analyze the data between 1980 and 1998 for 105 countries. EKC assumes that low-income countries increase their nuclear reliance in total electric production whereas high-income countries decrease their nuclear reliance. Hence, we expect that high-income countries should shut down existing nuclear reactors and/or not build any new ones. We encounter two reasons for shutdowns: economic or political/environmental concerns. To distinguish these two effects, reasons for shut down are also investigated by using the Hazard Model technique. Hence, the load factor of a reactor is used as an approximation for economic reason to shut down the reactor. If a shut downed reactor had high load factor, this could be attributable to political/environmental concern or else economic concern. The only countries with nuclear power are considered in this model. The two data sets are created. In the first data set, the single entry for each reactor is created as of 1998 whereas in the second data set, the multiple entries are created for each reactor beginning from 1980 to 1998. The dependent variable takes 1 if operational or zero if shut downed. The empirical findings provide strong evidence for EKC relationship for commercial nuclear electric generation. Furthermore, higher natural resources suggest alternative electric generation methods rather than nuclear power. Economic index as an institutional variable suggests higher the economic freedom, lower the nuclear electric generation as expected. This model does not support the idea to cut the carbon dioxide emission via increasing nuclear share. The Hazard Model findings suggest that higher the load factor is, less likely the reactor will shut down. However, if it is still permanently closed downed, then this could be attributable to political hostility against nuclear power. There are also some projections indicating which reactors are most/least likely to be shut downed from the logit model. We also project which countries are most likely to increase/decrease their nuclear reliance from the residuals of EKC model.

    This pilot study tested the effects of an interactive nutrition education Web site on fruit, vegetable, and fat consumption in minority adolescents genetically at risk for Type 2 diabetes. A one-group nonexperimental pretest, posttest focus group design was used. Twenty-one sixth-grade to eighth-grade junior high adolescents who were minorities volunteered to participate. Participants received 5 hours of Web-based nutrition education over 3 weeks. A significant difference in fat consumption was supported from the computerized dietary assessment. No difference was found in fruit or vegetable consumption. Comparative data indicated a rise in body mass index (BMI) percentile from 88.03 (1999) to 88.40 (2002; boys) and 88.25 (1999) to 91.2 (2002; girls). Focus group responses supported the satisfaction of adolescents in the study with the use of the Web-based intervention for nutrition education. Healthy eating interventions using Web-based nutrition education should be further investigated with adolescents.

    A new search system utilizing Atomindex is expounded. The nuclear information system of United States of America will be shifted to the larger scale system, Atomindex, at the moment of discontinuing the publication of Nuclear Science Abstract (NSA). This shifting exerts large or small influence upon the information systems of the other countries. The Atomindex is a publication of the International Nuclear Information System (INIS), and it includes most market unavailable reports. It is delivered through the clearing house to the users. Main differences between INIS and NSA are illustrated. Each piece of literature is listed under one or more descriptor pairs. Each pair is composed of the main heading and its qualifier, both of which are descriptors. Atomindex employs four working languages, namely English, French, Russian and Spanish. However, a version in the original language, even when this is not a working language can be recorded on magnetic tapes. Many special characters (suffixes, Greek, etc.) as well as alphabet are used, and italic type or boldface can be designated, so that the quality of Atomindex is better than that of NSA. The tapes for SDI and RS will be utilized as on-line real time systems. The second generation that utilizes the computer seems to be superseding the first generation that turns over the abstracts page by page. (Iwakiri, K.)

  13. Vertical vector face lift.

    Somoano, Brian; Chan, Joanna; Morganroth, Greg

    2011-01-01

    Facial rejuvenation using local anesthesia has evolved in the past decade as a safer option for patients seeking fewer complications and minimal downtime. Mini- and short-scar face lifts using more conservative incision lengths and extent of undermining can be effective in the younger patient with lower face laxity and minimal loose, elastotic neck skin. By incorporating both an anterior and posterior approach and using an incision length between the mini and more traditional face lift, the Vertical Vector Face Lift can achieve longer-lasting and natural results with lesser cost and risk. Submentoplasty and liposuction of the neck and jawline, fundamental components of the vertical vector face lift, act synergistically with superficial musculoaponeurotic system plication to reestablish a more youthful, sculpted cervicomental angle, even in patients with prominent jowls. Dramatic results can be achieved in the right patient by combining with other procedures such as injectable fillers, chin implants, laser resurfacing, or upper and lower blepharoplasties. © 2011 Wiley Periodicals, Inc.

  14. Successful decoding of famous faces in the fusiform face area.

    Directory of Open Access Journals (Sweden)

    Vadim Axelrod

    Full Text Available What are the neural mechanisms of face recognition? It is believed that the network of face-selective areas, which spans the occipital, temporal, and frontal cortices, is important in face recognition. A number of previous studies indeed reported that face identity could be discriminated based on patterns of multivoxel activity in the fusiform face area and the anterior temporal lobe. However, given the difficulty in localizing the face-selective area in the anterior temporal lobe, its role in face recognition is still unknown. Furthermore, previous studies limited their analysis to occipito-temporal regions without testing identity decoding in more anterior face-selective regions, such as the amygdala and prefrontal cortex. In the current high-resolution functional Magnetic Resonance Imaging study, we systematically examined the decoding of the identity of famous faces in the temporo-frontal network of face-selective and adjacent non-face-selective regions. A special focus has been put on the face-area in the anterior temporal lobe, which was reliably localized using an optimized scanning protocol. We found that face-identity could be discriminated above chance level only in the fusiform face area. Our results corroborate the role of the fusiform face area in face recognition. Future studies are needed to further explore the role of the more recently discovered anterior face-selective areas in face recognition.

  15. How Well Do Computer-Generated Faces Tap Face Expertise?

    Directory of Open Access Journals (Sweden)

    Kate Crookes

    Full Text Available The use of computer-generated (CG stimuli in face processing research is proliferating due to the ease with which faces can be generated, standardised and manipulated. However there has been surprisingly little research into whether CG faces are processed in the same way as photographs of real faces. The present study assessed how well CG faces tap face identity expertise by investigating whether two indicators of face expertise are reduced for CG faces when compared to face photographs. These indicators were accuracy for identification of own-race faces and the other-race effect (ORE-the well-established finding that own-race faces are recognised more accurately than other-race faces. In Experiment 1 Caucasian and Asian participants completed a recognition memory task for own- and other-race real and CG faces. Overall accuracy for own-race faces was dramatically reduced for CG compared to real faces and the ORE was significantly and substantially attenuated for CG faces. Experiment 2 investigated perceptual discrimination for own- and other-race real and CG faces with Caucasian and Asian participants. Here again, accuracy for own-race faces was significantly reduced for CG compared to real faces. However the ORE was not affected by format. Together these results signal that CG faces of the type tested here do not fully tap face expertise. Technological advancement may, in the future, produce CG faces that are equivalent to real photographs. Until then caution is advised when interpreting results obtained using CG faces.

    The facial width-to-height ratio (face ratio), is a sexually dimorphic metric associated with actual aggression in men and with observers' judgements of aggression in male faces. Here, we sought to determine if observers' judgements of aggression were associated with the face ratio in female faces. In three studies, participants rated photographs of female and male faces on aggression, femininity, masculinity, attractiveness, and nurturing. In Studies 1 and 2, for female and male faces, judgements of aggression were associated with the face ratio even when other cues in the face related to masculinity were controlled statistically. Nevertheless, correlations between the face ratio and judgements of aggression were smaller for female than for male faces (F1,36 = 7.43, p = 0.01). In Study 1, there was no significant relationship between judgements of femininity and of aggression in female faces. In Study 2, the association between judgements of masculinity and aggression was weaker in female faces than for male faces in Study 1. The weaker association in female faces may be because aggression and masculinity are stereotypically male traits. Thus, in Study 3, observers rated faces on nurturing (a stereotypically female trait) and on femininity. Judgements of nurturing were associated with femininity (positively) and masculinity (negatively) ratings in both female and male faces. In summary, the perception of aggression differs in female versus male faces. The sex difference was not simply because aggression is a gendered construct; the relationships between masculinity/femininity and nurturing were similar for male and female faces even though nurturing is also a gendered construct. Masculinity and femininity ratings are not associated with aggression ratings nor with the face ratio for female faces. In contrast, all four variables are highly inter-correlated in male faces, likely because these cues in male faces serve as “honest signals”. PMID:22276184

    In the context of world-wide strategies for the reduction of climatic gases the CCS technology (CCS = carbon capture and sequestration) highlights a great importance. In individual areas the capture of carbon dioxide occurs commercially. However, the losses of the efficiency in the operation of power stations must be reduced by the separation and processing of carbon dioxide. A construction of a demonstration unit is particularly important. On this basis, diaphragm-based procedures, procedures for oxygen production as well as the dry sorption of carbon dioxide are promising. The technical and chemical utilization of carbon dioxide can offer an interesting approach for the direct reduction of the global emissions of carbon dioxide.

    Visual images that are not faces are sometimes perceived as faces (the pareidolia phenomenon). While the pareidolia phenomenon provides people with a strong impression that a face is present, it is unclear how deeply pareidolia faces are processed as faces. In the present study, we examined whether a shift in spatial attention would be produced by gaze cueing of face-like objects. A robust cueing effect was observed when the face-like objects were perceived as faces. The magnitude of the cuei...

    Although the human brain may have evolutionarily adapted to face-to-face communication, other modes of communication, e.g., telephone and e-mail, increasingly dominate our modern daily life. This study examined the neural difference between face-to-face communication and other types of communication by simultaneously measuring two brains using a hyperscanning approach. The results showed a significant increase in the neural synchronization in the left inferior frontal cortex during a face-to-face dialog between partners but none during a back-to-back dialog, a face-to-face monologue, or a back-to-back monologue. Moreover, the neural synchronization between partners during the face-to-face dialog resulted primarily from the direct interactions between the partners, including multimodal sensory information integration and turn-taking behavior. The communicating behavior during the face-to-face dialog could be predicted accurately based on the neural synchronization level. These results suggest that face-to-face communication, particularly dialog, has special neural features that other types of communication do not have and that the neural synchronization between partners may underlie successful face-to-face communication.

    While blended learning combines online and face-to-face teaching, research on blended learning has primarily focused on the role of technology and the opportunities it creates for engaging students. Less focus has been put on face-to-face activities in blended learning. This paper argues...... that it is not only the online activities in blended learning that provide new opportunities for rethinking pedagogy in higher education, it is also imperative to reconsider the face-to-face activities when part of the learning is provided online. Based on a review of blended learning in business and management...... education, we identify what forms of teaching and learning are suggested to take place face-to-face when other activities are moved online. We draw from the Community of Inquiry framework to analyze how face-to-face activities contribute to a blended learning pedagogy and discuss the implications...

  15. Human faces are slower than chimpanzee faces.

    Directory of Open Access Journals (Sweden)

    Anne M Burrows

    Full Text Available While humans (like other primates communicate with facial expressions, the evolution of speech added a new function to the facial muscles (facial expression muscles. The evolution of speech required the development of a coordinated action between visual (movement of the lips and auditory signals in a rhythmic fashion to produce "visemes" (visual movements of the lips that correspond to specific sounds. Visemes depend upon facial muscles to regulate shape of the lips, which themselves act as speech articulators. This movement necessitates a more controlled, sustained muscle contraction than that produced during spontaneous facial expressions which occur rapidly and last only a short period of time. Recently, it was found that human tongue musculature contains a higher proportion of slow-twitch myosin fibers than in rhesus macaques, which is related to the slower, more controlled movements of the human tongue in the production of speech. Are there similar unique, evolutionary physiologic biases found in human facial musculature related to the evolution of speech?Using myosin immunohistochemistry, we tested the hypothesis that human facial musculature has a higher percentage of slow-twitch myosin fibers relative to chimpanzees (Pan troglodytes and rhesus macaques (Macaca mulatta. We sampled the orbicularis oris and zygomaticus major muscles from three cadavers of each species and compared proportions of fiber-types. Results confirmed our hypothesis: humans had the highest proportion of slow-twitch myosin fibers while chimpanzees had the highest proportion of fast-twitch fibers.These findings demonstrate that the human face is slower than that of rhesus macaques and our closest living relative, the chimpanzee. They also support the assertion that human facial musculature and speech co-evolved. Further, these results suggest a unique set of evolutionary selective pressures on human facial musculature to slow down while the function of this muscle

    2016-02-01

    This study aimed to develop a clinical test of face perception which is applicable to a wide range of patients and can capture normal variability. The Caledonian face test utilises synthetic faces which combine simplicity with sufficient realism to permit individual identification. Face discrimination thresholds (i.e. minimum difference between faces required for accurate discrimination) were determined in an "odd-one-out" task. The difference between faces was controlled by an adaptive QUEST procedure. A broad range of face discrimination sensitivity was determined from a group (N=52) of young adults (mean 5.75%; SD 1.18; range 3.33-8.84%). The test is fast (3-4 min), repeatable (test-re-test r(2)=0.795) and demonstrates a significant inversion effect. The potential to identify impairments of face discrimination was evaluated by testing LM who reported a lifelong difficulty with face perception. While LM's impairment for two established face tests was close to the criterion for significance (Z-scores of -2.20 and -2.27) for the Caledonian face test, her Z-score was -7.26, implying a more than threefold higher sensitivity. The new face test provides a quantifiable and repeatable assessment of face discrimination ability. The enhanced sensitivity suggests that the Caledonian face test may be capable of detecting more subtle impairments of face perception than available tests. Copyright © 2015 Elsevier Ltd.
