    2003-01-01

    Objective: To demonstrate that Philip Morris and British American Tobacco Company attempted to initiate a wide ranging campaign to undermine the success of the 8th World Conference on Tobacco or Health held in Buenos Aires, Argentina, in 1992. Data sources: Publicly available tobacco industry documents housed in Minneapolis, Minnesota, USA; Guilford, UK; on-line document websites; and telephone interviews with informed parties. Study selection: Those documents determined to be relevant to the companies' campaigns against the 8th World Conference on Tobacco or Health. Data extraction: Revision of chapter VIII of the July 2000 WHO report by a committee of experts, entitled: Tobacco company strategies to undermine tobacco control activities at the World Health Organization: report of the committee of experts on tobacco industry documents. Data synthesis: Internal documents describe proposed media and science orientated campaigns developed by BAT, Philip Morris, and their consultants to divert attention away from the conference. Results and conclusion: This work shows that the tobacco industry has the resources and vested interest to combat perceived threats in its regional operating markets, in this case its Latin American market. It is important for the worldwide public heath community to become aware of the numerous ways in which the tobacco industry and its front groups can work against international tobacco control meetings, even including the manipulation of or working with other public health groups to oppose tobacco control efforts. Future world conference planners and participants should be aware that the tobacco industry is likely to continue to employ such methodology. There is no reason to think that the industry is paying less attention to such conferences in the present or future. Rather, it is likely the industry will adopt and expand strategies that were successful while abandoning those that were not effective. Required disclosure of financial support

    The Human Disease Glycomics/Proteomics Initiative (HGPI) Session at the HUPO World Congress was held in Toronto on 26 September 2009. In this report, we summarize the presentation of the HGPI workshop as follows: (i) The results of the past HGPI pilot studies (first and second) in which we analyzed N- and O-linked glycans using standard glycoproteins (i.e. first: N-linked glycan analysis of transferrin and IgG; second: O-linked glycan analysis of IgA). (ii) The recent progresses of the current HGPI third pilot study. The third analytical pilot study is in progress to perform the two tasks, which are glycan structural analysis and identification of proteins which carry specific carbohydrate antigen (Lewis X antigen) using cancer cells (i.e. L428, U937, and SK-N-SH), under the theme of "Glyco-Biomarker Discovery". Finally, recently advanced glycomic and glycoproteomic analyses were also reported.

    On June 10, 1886, Mt. Tarawera in the rhyolitic Okataina Volcanic Centre of the central North Island, New Zealand, erupted in spectacular fashion. Basaltic eruptions at Tarawera produced tall eruption columns, while hydrothermal and phreatomagmatic eruptions at Rotomahana excavated the pre-1886 Lake Rotomahana site, which later filled to form a new lake up to 125 m deep and ~5 x larger than its predecessor. The Pink and White Terraces, which were the world's largest silica aprons and buttresses, had formed as a result of discharging thermal waters and deposition of silica on the margins of the pre-1886 lake, and were believed destroyed during the 1886 eruption. The post-eruption landscape was scarred by eruption craters with the largest marking the foci of the phreatomagmatic eruption, which blanketed the area with 10s of m of mud. A combined ~250 line km survey of Lake Rotomahana was conducted using two REMUS 100 AUVs simultaneously mapping with multibeam and sidescan sonar. Also fitted were a magnetometer, minature plume recorders (LSS, Eh, temperature, depth) and pH sensors. Surface vessels conducted magnetic surveys (110 line km), CO2 flux measurements (420 sites), deployed a CTD and Niksin bottles for water properties and sampling (14 stations), and a camera over sites (12) of known venting and/or where the sidescan showed evidence for the terraces. New bathymetric data clearly shows the en-echelon rift of 1886 in the center of the lake and identifies some pre-1886 shoreline. When combined with sidescan sonar images, several of the basal layers of the Pink Terraces were found very near their original, pre-eruption locations. Underwater photographs reveal buttresses of several tiers. Magnetic data show a pronounced positive anomaly in the southern part of the lake, associated with older lavas, and a distinct negative anomaly associated with the Pink Terraces, marking the boundaries of the pre-1886 geothermal field. Bubble plumes recorded during the magnetic

  16. Integrating WorldWide Telescope with Wordpress

    NASA Astrophysics Data System (ADS)

    Sands, Mark; Luebbert, J.; Fay, J.; Gay, P. L.

    2010-01-01

    In this project we unite three major components of astronomy and new media: World Wide Telescope, Wordpress, and user supplied audio. Through an easy to use Wordpress plug-in users can create WorldWide Telescope sky tours that allow: a) astronomers and educators to spread the facts and awareness of astronomy, potentially bringing new and interested individuals into the astronomy community; b) bloggers/podcasters to create dynamic, virtual tours of the universe that are nearly boundless; and, c) readers to benefit from the alluring WorldWide Telescope tours by gaining a new and dramatic outlook on our universe. This software has the potential to augment, and in some cases replace, traditional methods of astronomy centered online lectures. With this plugin, it is possible to combine Wordpress-based website content with audio, and a sky tour that can be paused at any object. This ability to pause a sky tour allows the user to further explore the wealth of data provided within WWT. This fully customizable solution includes all of the necessary features required to reproduce a lecture in a more creative and appealing format then some of the standard, typically non-interactive, movies and podcasts currently found online. Through the creation of effective WorldWide Telescope tours, astronomers and educators can better extend astronomy content to astronomy-interested, but not yet engaged, members of the new media community. These tours will provide a better understanding and appreciation for what our universe has to offer. Through this new media approach of integrating WorldWide Telescope with blogs and podcasts, users can now extend their interest in astronomy by exploring the universe themselves, moving beyond provided content to gain a better understanding all on their own.

    The World Wide Web has brought the information from a distributed environment into a global information universe. As users keep on surfing the Web and adding their bookmarks, it is increasingly difficult for them to find their desired information even though there are many search tools available. In this paper, a smart engineering system called Cyber Agent is proposed to help users search and organize the information. It contains two major subsystems, namely, WebTracer and WebOrganizer. They adapt their behavior dynamically according to the environment and the special preferences of each individual. WebTracer is the wavefront of the Cyber Agent while WebOrganizer is the brain of the Cyber Agent.

    1988-01-01

    INMARSAT decided to expand the spectrum covered by its new generation of satellites, INMARSAT-2, to include 1 MHz (subsequently increased to 3 MHz) of the spectrum designed for aeronautical use. It began a design study that led to the specifications for the system that is now being implemented. Subsequently, INMARSAT awarded contracts for the design of avionics and high gain antennas to a number of manufactures, while several of the signatories that provide ground equipment for communicating with the INMARSAT satellites are modifying their earth stations to work with the avionic equipment. As a resullt of these activities, a world-wide aeronautical satellite system supporting both voice and data will become operational in 1989.

    Gullberg, B; Johnell, O; Kanis, J A

    1997-01-01

    The aims of this study were to estimate the present and future incidence of hip fracture world-wide. From a survey of available data on current incidence, population trends and the secular changes in hip fracture risk, the numbers of hip fractures expected in 2025 and 2050 were computed. The total number of hip fractures in men and women in 1990 was estimated to be 338,000 and 917,000 respectively, a total of 1.26 million. Assuming no change in the age- and sex-specific incidence, the number of hip fractures is estimated to approximately double to 2.6 million by the year 2025, and 4.5 million by the year 2050. The percentage increase will be greater in men (310%) than in women (240%). With modest assumptions concerning secular trends, the number of hip fractures could range between 7.3 and 21.3 million by 2050. The major demographic changes will occur in Asia. In 1990, 26% of all hip fractures occurred in Asia, whereas this figure could rise to 37% in 2025 and to 45% in 2050. We conclude that the socioeconomic impact of hip fractures will increase markedly throughout the world, particularly in Asia, and that there is an urgent need to develop preventive strategies, particularly in the developing countries.

  2. Developing Basic Space Science World-Wide

    2004-03-01

    When the first United Nations/European Space Agency Workshop for Basic Space Science was planned to be held in Bangalore, India (1991) on the invitation of ISRO, few of those involved could expect that a unique forum was going to be created for scientific dialogue between scientists from developing and industrialized nations. As the format of the first workshop was on purpose left free with time for presentations, working sessions, and plenary discussions, the workshop was left to find its own dynamics. After a decade of UN/ESA Workshops, this book brings together the historical activities, the plans which have been developed over the past decade in the different nations, and the results which have materialized during this time in different developing nations. It aims to achieve for development agencies to be assisted in ways to find more effective tools for the application of development aid. The last section of the book contains a guide for teachers to introduce astrophysics into university physics courses. This will be of use to teachers in many nations. Everything described in this book is the result of a truly collective effort from all involved in all UN/ESA workshops. The mutual support from the participants has helped significantly to implement some of the accomplishments described in the book. Rather than organizing this book in a subject driven way, it is essentially organized according to the common economic regions of the world, as defined by the United Nations (Africa, Asia and the Pacific, Europe, Latin America and the Caribbean, Western Asia). This allows better recognition of the importance of a regional (and at times) global approach to basic space science for the developing nation's world wide. It highlights very specific scientific investigations which have been completed successfully in the various developing nations. The book supplements the published ten volumes of workshop proceedings containing scientific papers presented in the workshops

    The Internet provides new opportunities to gather information on the population and may provide alternatives to the traditional methods of conducting clinical trials in systemic lupus erythematosus. The 'world wide web-www' has grown extensively in the past decade and it is estimated that there will be over 1 billion individuals on the net by the year 2005. Notifying, recruiting and assessing patients using Internet technology are already potential uses of this electronic medium. However, total reliance on the Internet could lead to biased sampling of patients with lupus. Women with low incomes or who are unemployed are less likely to have access to the Internet. Individuals with neurological deficits may have trouble using the Internet effectively. Data collected on the web may not have high reliability and much work needs to be completed to determine the psychometric properties of information derived from this source. One of the greatest threats to contend with is protecting the confidentiality of patient information when using electronic communication. Safeguards against inadvertent or unintended release of information must receive high priority in any attempt to use the Internet for clinical trials. Particular attention should be paid to email messages, which have the potential to be intercepted or sent to individuals without clearance to see patient information. Nevertheless, the costs to systems performance caused by security measures must also be considered and balanced against the need for access by those with appropriate authority. A number of websites already exist for the benefit of patients and providers. Clinicians and scientists interested in the field of lupus research will need to keep up to date on the rapidly proliferating information that is becoming available. This article lists sites which can be visited now.

    `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. The benefits In fact, Astronomy On-Line will be the first

    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.

    The Internet has changed astronomy. It's changed research, outreach and education and it's changed how people consume astronomy as enthusiasts. People have new ways to talk to each other and new ways to participate. Coined ``Web 2.0,'' technologies such as blogs, social networks, wikis, photo and video sharing sites, podcasts and micro-blogging have been adopted by the astronomy community and exciting things are happening as a result. The International Year of Astronomy's New Media Task Force has been working to harness the excitement of ``Web 2.0'' to make the International Year of Astronomy (IYA2009) highly visible on the Internet around the world.

  9. Wildfire contribution to world-wide desertification.

    NASA Astrophysics Data System (ADS)

    Neary, D.; Wittenberg, L.; Bautista, S.; Ffolliott, P.

    2009-04-01

    Wildfire is a natural phenomenon that began with the development of terrestrial vegetation in a lightning-filled atmosphere. Sediments from the Carboniferous Period (307-359 million years before the present) contain evidence of charcoal from post-fire ash slurry flows. As human populations developed in the Pleistocene and Holocene epochs, mankind transformed fire into one of its oldest tools. Human and natural ignited fires from lightning altered and steered the trajectories of ecosystem development in most parts of the world. Humans are now the primary source of forest and grass fire ignitions throughout the world. As human populations have increased and industrialized in the past two centuries, fire ignitions and burned areas have increased due to both sheer numbers of people and anthropogenic changes in the global climate. Recent scientific findings have bolstered the hypothesis that climate change is resulting in fire seasons starting earlier, lasting longer, burning greater areas, and being more severe Computer models point to the Western U.S., Mediterranean nations and Brazil as "hot spots" that will get extremes at their worst. The climatic change to drier and warmer conditions has the potential to aggravate wildfire conditions, resulting in burning over longer seasons, larger areas of vegetation conflagration, and higher fire severities. Wildfire is now driving desertification in some of the forest lands in the western United States. The areas of wildfire in the Southwest USA have increased dramatically in the past two decades from <10,000 ha yr-1 in the early 20th Century to over 230,000 ha yr-1 in the first decade of the 21st Century. Individual wildfires are now larger and produce higher severity burns than in the past. A combination of natural drought, climate change, excessive fuel loads, and increased ignition sources have produced the perfect conditions for fire-induced desertification. Portugal suffered the worst and second worst wildfire seasons in

    Andrew Hutton, Adam Carpenter

    2011-03-01

    The speaker will review and analyze the performance of existing SRF facilities in the world, addressing issues of usage and availability for different customers (HEP research, material sciences, ADS). Lessons learned should be summarized for proposed future facilities (ILC, Project X, Muon Collider). The first use of superconducting cavities for accelerating beams was at HEPL, Stanford University in the early sixties. Rather quickly, other laboratories followed suit, notably the University of Illinois at Champagne, Urbana and Cornell University. There were two main uses, which still persist today. The first is to provide accelerated particles as an injector or for fixed target experiments. The second is to maintain circulating beams, either for synchrotron light sources or for colliding beam experiments. Given the differing requirements, these two uses led to rather different implementations and, in particular, different average operating gradients. A second difference in the implementation is the speed of the particle being accelerated. Electrons are sufficiently relativistic at low beam energies (> {approx} 5 MeV) that cavities designed for relativistic beams can also function acceptably at low energy. This is not the case for protons or ion accelerators so, until recently, copper cavities were used to cover the first {approx} 100 MeV. Superconducting cavities are now also being proposed to cover this energy range as well using a series of superconducting cavities, each of which is matched to the particle velocity.

    The 8th European Antibody Congress (EAC), organized by Terrapin Ltd., was again held in Geneva, Switzerland, following on the tradition established with the 4th EAC. The new agenda format for 2012 included three parallel tracks on: (1) naked antibodies; (2) antibody drug conjugates (ADCs); and (3) bispecific antibodies and alternative scaffolds. The meeting started and closed with three plenary lectures to give common background and to share the final panel discussion and conclusions. The two day event included case studies and networking for nearly 250 delegates who learned of the latest advances and trends in the global development of antibody-based therapeutics. The monoclonal antibody track was focused on understanding the structure-function relationships, optimization of antibody design and developability, and processes that allow better therapeutic candidates to move through the clinic. Discussions on novel target identification and validation were also included. The ADC track was dedicated to evaluation of the ongoing success of the established ADC formats alongside the rise of the next generation drug-conjugates. The bispecific and alternative scaffold track was focused on taking stock of the multitude of bispecific formats being investigated and gaining insight into recent innovations and advancements. Mechanistic understanding, progression into the clinic and the exploration of multispecifics, redirected T cell killing and alternative scaffolds were extensively discussed. In total, nearly 50 speakers provided updates of programs related to antibody research and development on-going in the academic, government and commercial sectors. PMID:23493119

  3. International organizations to enable world-wide mobile satellite services

    NASA Technical Reports Server (NTRS)

    Anglin, Richard L., Jr.

    1993-01-01

    Numbers of systems exist or have been proposed to provide world-wide mobile satellite services (MSS). Developers of these systems have formulated institutional structures they consider most appropriate for profitable delivery of these services. MSS systems provide niche services and complement traditional telecommunications networks; they are not integrated into world-wide networks. To be successful, MSS system operators must be able to provide an integrated suite of services to support the increasing globalization, interconnectivity, and mobility of business. The critical issue to enabling 'universal roaming' is securing authority to provide MSS in all of the nations of the world. Such authority must be secured in the context of evolving trends in international telecommunications, and must specifically address issues of standardization, regulation and organization. Today, only one existing organization has such world-wide authority. The question is how proponents of new MSS systems and services can gain similar authority. Securing the appropriate authorizations requires that these new organizations reflect the objectives of the nations in which services are to be delivered.

  4. World-wide increase in tropospheric methane, 1978-1983

    NASA Technical Reports Server (NTRS)

    Blake, D. R.; Rowland, F. S.

    1986-01-01

    Techniques used to assess methane concentration in the troposphere are described, and data obtained during the period from 1978 to 1983 are presented in detail. Tropospheric methane concentrations in remote locations averaged a yearly world-wide increase of 0.018 + or - 0.002 parts per million by volume (ppmv). Average world-wide tropospheric concentration of methane in dry air was 1.625 ppmv at the end of 1983 measured against an NBS standard certified as 0.97 ppmv. Contributing to this steady increase in methane concentration are increases in the source strengths from cattle and rice fields, which in turn result from CO, CH4 and HO coupling. Among the physical and chemical effects is an increase in greenhouse warming of about 0.04 C per decade.

  5. Wired World-Wide Web Interactive Remote Event Display

    SciTech Connect

    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.

    Klavans, Richard; Boyack, Kevin W.

    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.

  10. Crystallography Open Databases and Preservation: a World-wide Initiative

    NASA Astrophysics Data System (ADS)

    Chateigner, Daniel

    In 2003, an international team of crystallographers proposed the Crystallography Open Database (COD), a fully-free collection of crystal structure data, in the aim of ensuring their preservation. With nearly 250000 entries, this database represents a large open set of data for crystallographers, academics and industrials, located at five different places world-wide, and included in Thomson-Reuters’ ISI. As a large step towards data preservation, raw data can now be uploaded along with «digested» structure files, and COD can be questioned by most of the crystallography-linked industrial software. The COD initiative work deserves several other open developments.

  14. Stardial: an Autonomous Astronomical Camera on the World Wide Web

    NASA Astrophysics Data System (ADS)

    McCullough, P.; Thakkar, U.

    1997-11-01

    We describe the use of an autonomous astronomical camera, called ``Stardial,'' for undergraduate instruction. Stardial delivers images of the night sky nearly in real-time to the world wide web (www.astro.uiuc.edu/~stardial/). The world wide web (WWW) interface is robust, inexpensive, and accommodates many students asynchronously with respect to the instructor(s). The guiding philosophy is to provide students with authentic astronomical data so that they may learn about science by doing it themselves. Students respond favorably to the opportunity to learn from their own experiences with authentic data, complete with its irregularities and its surprises. Stardial has been operational for one academic year (1996-97) at the University of Illinois at Urbana-Champaign. In this paper we describe Stardial's instrumentation, some of the curriculum based upon Stardial's unique data, and the experiences of students who have used Stardial. We conclude with possible research topics using Stardial data and with a brief look to the future of remote laboratories. (SECTION: Astronomical Instrumentation) The name ``Stardial'' derives from the fact that like a sundial, Stardial is a stationary device placed outside 24 hours a day, and that both depend on and make evident the rotation of the Earth. A sundial operates with sunlight, while Stardial operates with starlight. There the similarity ends.

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

    USGS Publications Warehouse

    Griffith, J.A.; Egbert, S.L.

    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.

    Udomprasert, Patricia S.; Goodman, A. A.; Wong, C.

    2013-01-01

    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.

  18. World wide web implementation of the Langley technical report server

    NASA Technical Reports Server (NTRS)

    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.

    PubMed

    Nicoll, L H

    2001-01-01

    In conclusion, the World Wide Web offers an incredible variety of resources, many of which are available free of charge. To begin accessing these resources, one must first become comfortable with using browser software. Once this is done, master the basics of searching. Keep in mind that for a search to be efficient, you should have a clear understanding of why you are doing the search, the basis of a Purpose-Focus-Assessment analysis. With this information in hand, you can dive in, using methods that range from broad and general--such as brute force--to highly focused and specific literature searching. Remember that although the most effective searches are those that are tailored to the situation at hand, all searching on the Internet requires persistence, tenacity, and a good dose of creative thinking!

    The world wide web provides a uniform, user friendly interface to the Internet. Web pages can contain text and pictures and are interconnected by hypertext links. The addresses of web pages are recorded as uniform resource locators (URLs), transmitted by hypertext transfer protocol (HTTP), and written in hypertext markup language (HTML). Programs that allow you to use the web are available for most operating systems. Powerful on line search engines make it relatively easy to find information on the web. Browsing through the web--"net surfing"--is both easy and enjoyable. Contributing to the web is not difficult, and the web opens up new possibilities for electronic publishing and electronic journals. Images p1554-a Fig 5 PMID:8520402

    PubMed

    Chalmers, Gordon R

    2005-01-01

    Health professionals and members of the public are often interested in locating exercise information on the World Wide Web (the Web). There is a large amount of information available on the Web; however, the challenge for all people is to identify the high quality information that can be depended upon. Much of the quality exercise information on the Web is hidden within sites of reputable organizations concerned with exercise and health. This article examines several categories of commonly needed exercise related information. For each category, a few high quality sources of exercise information are listed. Combined, these Web sites provide an excellent and extensive body of knowledge for a person who is not experienced with exercise and wants to get started learning, or for a person with a moderate level of experience and knowledge who wants to learn more.

  2. WorldWide Telescope in High School Astronomy Competitions

    NASA Astrophysics Data System (ADS)

    Constantin, Ana-Maria; Goodman, A. A.; Udomprasert, P. S.

    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.

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

    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.

  4. Accessing NASA Technology with the World Wide Web

    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.

  5. Weighted median image sharpeners for the World Wide Web.

    PubMed

    Fischer, Marco; Paredes, José L; Arce, Gonzalo R

    2002-01-01

    A class of robust weighted median (WM) sharpening algorithms is developed in this paper. Unlike traditional linear sharpening methods, weighted median sharpeners are shown to be less sensitive to background random noise or to image artifacts introduced by JPEG and other compression algorithms. These concepts are extended to include data dependent weights under the framework of permutation weighted medians leading to tunable sharpeners that, in essence, are insensitive to noise and compression artifacts. Permutation WM sharpeners are subsequently generalized to smoother/sharpener structures that can sharpen edges and image details while simultaneously filter out background random noise. A statistical analysis of the various algorithms is presented, theoretically validating the characteristics of the proposed sharpening structures. A number of experiments are shown for the sharpening of JPEG compressed images and sharpening of images with background film-grain noise. These algorithms can prove useful in the enhancement of compressed or noisy images posted on the World Wide Web (WWW) as well as in other applications where the underlying images are unavoidably acquired with noise.

    2007-01-01

    Nosocomial infections are a major worldwide cause of death and disability, infection control programs are effective in limiting these infections, especially those acquired in the intensive care unit. The development of the world wide web has provided health care professionals with immediate access to continuously updated information in the field of infection control. We sought to identify websites that contain information on nosocomial infection control by using popular internet search engines, such as Google, Yahoo and AltaVista, and by reviewing relevant publications identified in the PubMed and Current Contents databases. Only those sites that were English language, open access, and developed by a government, academic institution, or national or international scientific association were eligible for inclusion. From a vast number of internet sites initially identified, we selected 49 that provide information on infection control for inclusion in our list of practical and relevant internet resources. Several sites provide general information on infection control practices, whereas others focus on one or a few specific infection(s). We provide health care professionals with a timely and succinct list of open access internet resources that contain information regarding the prevention and control of nosocomial infections in order to help in the dissemination of relevant information and so contribute to the limitation of such hazards.

    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.

    The WorldWide Telescope computer program, released to researchers and the public as a free resource in 2008 by Microsoft Research, has changed the way the ever-growing Universe of online astronomical data is viewed and understood. The WWT program can be thought of as a scriptable, interactive, richly visual browser of the multi-wavelength Sky as we see it from Earth, and of the Universe as we would travel within it. In its web API format, WWT is being used as a service to display professional research data. In its desktop format, WWT works in concert (thanks to SAMP and other IVOA standards) with more traditional research applications such as ds9, Aladin and TOPCAT. The WWT Ambassadors Program (founded in 2009) recruits and trains astrophysically-literate volunteers (including retirees) who use WWT as a teaching tool in online, classroom, and informal educational settings. Early quantitative studies of WWTA indicate that student experiences with WWT enhance science learning dramatically. Thanks to the wealth of data it can access, and the growing number of services to which it connects, WWT is now a key linking technology in the Seamless Astronomy environment we seek to offer researchers, teachers, and students alike.

    The distribution of numbers in human documents is determined by a variety of diverse natural and human factors, whose relative significance can be evaluated by studying the numbers’ frequency of occurrence. Although it has been studied since the 1880's, this subject remains poorly understood. Here, we obtain the detailed statistics of numbers in the World Wide Web, finding that their distribution is a heavy-tailed dependence which splits in a set of power-law ones. In particular, we find that the frequency of numbers associated to western calendar years shows an uneven behavior: 2004 represents a ‘singular critical’ point, appearing with a strikingly high frequency; as we move away from it, the decreasing frequency allows us to compare the amounts of existing information on the past and on the future. Moreover, while powers of ten occur extremely often, allowing us to obtain statistics up to the huge 10127, ‘non-round’ numbers occur in a much more limited range, the variations of their frequencies being dramatically different from standard statistical fluctuations. These findings provide a view of the array of numbers used by humans as a highly non-equilibrium and inhomogeneous system, and shed a new light on an issue that, once fully investigated, could lead to a better understanding of many sociological and psychological phenomena.

  10. Documentation of the AMIP models on the World Wide Web

    1995-08-01

    The intercomparison of atmospheric general circulation model (AGCM) experiments of a similar type has become an increasingly popular methodology for assessing the strengths and weaknesses of climate simulations. In such endeavors, attempts to attribute differences among the simulations to specific model properties require, as a minimum prerequisite, the accurate and comprehensive documentation of these features. Regrettably however, atmospheric model documentation typically is fragmentary and scattered across numerous publications. It is also often inaccurate, in the sense that the pace of model development and the proliferation of new model versions usually outstrip their recorded descriptions. More often than not, the detailed configuration of a model for a particular experiment also is undocumented. In addition, there may be much unevenness in the descriptions of different facets of models. This incompleteness usually is replicated in published results of an intercomparison experiment, in that participating models` features often are summarized only perfunctorily. Summary documentation of the numerics, dynamics, and physics of models participating in the Atmospheric Model Intercomparison Project (AMIP) is now available on the Internet`s World Wide Web. This paper describes the principal attributes of the electronic model documentation and provides instructions on how to access it.

  11. Browsing the World Wide Web from behind a firewall

    1995-02-01

    The World Wide Web provides a unified method of access to various information services on the Internet via a variety of protocols. Mosaic and other browsers give users a graphical interface to the Web that is easier to use and more visually pleasing than any other common Internet information service today. The availability of information via the Web and the number of users accessing it have both grown rapidly in the last year. The interest and investment of commercial firms in this technology suggest that in the near future, access to the Web may become as necessary to doing business as a telephone. This is problematical for organizations that use firewalls to protect their internal networks from the Internet. Allowing all the protocols and types of information found in the Web to pass their firewall will certainly increase the risk of attack by hackers on the Internet. But not allowing access to the Web could be even more dangerous, as frustrated users of the internal network are either unable to do their jobs, or find creative new ways to get around the firewall. The solution to this dilemma adopted at Sandia National Laboratories is described. Discussion also covers risks of accessing the Web, design alternatives considered, and trade-offs used to find the proper balance between access and protection.

    The LBNL/UCSF Resource for Molecular Cytogenetics has been created to facilitate the application of molecular cytogenetics in clinical and biological studies. One of the primary tasks is the selection of probes optimized for use in fluorescence in situ hybridization (FISH). Our group provides data management support for all the activities in the Resource. In this paper we describe an electronic laboratory notebook based on the World Wide Web. The data are located in a central database. The user interface consists of a set of HTML forms that handle data input and retrieval from a database from two locations several miles apart. A WWW client allows users to formulate retrieval and edit operations that are sent to the database. Results are filtered through Perl scripts which generate HTML documents with Hypertext links that are sent back to the client. Besides tracking laboratory information through the various stages in the biology laboratory, the system also feeds into a public web server that makes the data available to the community.

  13. Searching for biomedical information on the World Wide Web.

    2000-01-01

    The rapid growth of biomedical information available via the Internet and its most popular retrieval system, the World Wide Web, has fostered active research and development directed toward locating resources that are appropriate for answering specific queries. The goal is to create tools that optimize information retrieval (as measured by two quantities, precision and recall) while minimizing the effort required by the user. Existing Web retrieval tools can be divided into the following groups: manually maintained topical lists; automatically generated word-based indices; software agents and multi-index searching aids; network cataloging methods; and miscellaneous hybrid and newer approaches. Improvements in current methods should arise from further research into: methods of describing objects on the Web; improved ways of searching for (and within) collections of documents as opposed to single documents; the ability to search for fielded documents; and ways to describe resources that span intra- and interdisciplinary as well as cross-cultural linguistic differences. For this last problem, the U.S. National Library of Medicine's Unified Medical Language System (UMLS) will be of great help. As online information retrieval improves, efforts are underway to improve the online information itself; quality control over content is being addressed as the peer-review systems of traditional printed journals migrate into the realm of electronic publication.

    We report preliminary results from an NSF-funded project to build, test, and research the impact of a WorldWide Telescope Visualization Lab (WWT Vizlab), meant to offer learners a deeper physical understanding of the causes of the Moon's phases. The Moon Phases VizLab is designed to promote accurate visualization of the complex, three dimensional Earth-Sun-Moon relationships required to understand the Moon's phases, while also providing opportunities for middle school students to practice critical science skills, like using models, making predictions and observations, and linking them in evidence-based explanations. In the VizLab, students use both computer-based models and lamp + ball physical models. We present findings from the first two phases of the study—one in which we compared learning gains from the WWT VizLab with a traditional two dimensional Moon phases simulator, and another in which we experimented with different ways of blending physical and virtual models in the classroom.

    Human exposure assessment is frequently noted as a weak link and bottleneck in the risk assessment process. Fortunately, the World Wide Web and Internet are providing access to numerous valuable sources of human exposure assessment-related information, along with opportunities for information exchange. Internet mailing lists are available as potential online help for exposure assessment questions, e.g. RISKANAL has several hundred members from numerous countries. Various Web sites provide opportunities for training, e.g. Web sites offering general human exposure assessment training include two from the US Environmental Protection Agency (EPA) and four from the US National Library of Medicine. Numerous other Web sites offer access to a wide range of exposure assessment information. For example, the (US) Alliance for Chemical Awareness Web site addresses direct and indirect human exposures, occupational exposures and ecological exposure assessments. The US EPA's Exposure Factors Program Web site provides a focal point for current information and data on exposure factors relevant to the United States. In addition, the International Society of Exposure Analysis Web site provides information about how this society seeks to foster and advance the science of exposure analysis. A major opportunity exists for risk assessors and others to broaden the level of exposure assessment information available via Web sites. Broadening the Web's exposure information could include human exposure factors-related information about country- or region-specific ranges in body weights, drinking water consumption, etc. along with residential factors-related information on air changeovers per hour in various types of residences. Further, country- or region-specific ranges on how various tasks are performed by various types of consumers could be collected and provided. Noteworthy are that efforts are underway in Europe to develop a multi-country collection of exposure factors and the European

    The connection between data warehousing and the metadata. used to catalog and locate warehouse data is obvious, but what is the connection between data warehousing, metadata, and the World Wide Web (WWW)? Specifically, the WWW can be used to allow users to search metadata (data about the data) and retrieve data from a warehouse database. In addition, the Internet/Intranet can be used to manage the metadata in archive databases and to streamline the database administration functions of a large archive center. The Oak Ridge National Laboratory`s (ORNL`s) Distributed Active Archive Center (DAAC) is a data archive and distribution center for the National Air and Space Administration`s (NASA`s) Earth Observing System Data and Information System (EOSDIS); the ORNL DAAC provides access to tabular and imagery datasets used in ecological and environmental research. To support this effort, we have taken advantage of the rather unique and user-friendly features of the WWW to (1) allow users to search for and download the data we archive and (2) provide DAAC developers with effective metadata and data management tools. In particular, the ORNL DAAC has developed the Biogeochemical Information Ordering Management Environment (BIOME), a WWW search-and-order system, as well as a WWW-based database administrator`s (DBA`s) tool suite designed to assist the site`s DBA in the management of archive metadata and databases and several other DBA functions that are essential to site management. This paper is a case study of how the ORNL DAAC uses the WWW to both manage data and allow access to its data warehouse.

  18. World-Wide Web Tools for Locating Planetary Images

    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

    2008-02-01

    In the thin, dry air of northern Chile's Atacama Desert, at an altitude of 16,500 feet, an amazing new telescope system is taking shape, on schedule to provide the world's astronomers with unprecedented views of the origins of stars, galaxies, and planets. The Atacama Large Millimeter/submillimeter Array (ALMA) will open an entirely new "window" on the Universe, allowing scientists to unravel longstanding and important astronomical mysteries. ALMA Artist's Concept Artist's Concept of Completed ALMA CREDIT: ALMA/ESO/NRAO/NAOJ Click on image for high-resolution file (182 KB) "Most of the photons in the Universe are in the wavelength range that ALMA will receive, and ALMA will give us our first high-resolution views at these wavelengths. This will be a tremendous advancement for astronomy and open one of our science's last frontiers," Anneila Sargent, a Caltech professor and ALMA Board member, told the American Association for the Advancement of Science at its meeting in Boston, Mass. The millimeter and submillimeter wavelength range lies between what is traditionally considered radio waves and infrared waves. ALMA, a system using up to 66 high-precision dish antennas working together, will provide astronomers with dramatically greater sensitivity, the ability to detect faint objects, and resolving power, the ability to see fine detail, than has ever before been available in this range. "This ambitious project is the product of an international collaboration that spans the globe," Sargent said. "ALMA truly will enable transformational science and providing this capability has required a massive, world-wide effort," she added. The ALMA project is a partnership between Europe, Japan and North America in cooperation with the Republic of Chile. ALMA is funded in Europe by ESO, in Japan by the National Institutes of Natural Sciences in cooperation with the Academia Sinica in Taiwan and in North America by the U.S. National Science Foundation in cooperation with the

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

    NASA Astrophysics Data System (ADS)

    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

  7. The 8th Century Megadrought Across North America

    2002-12-01

    Tree-ring data suggest that the 8th and 16th century megadroughts may have been the most severe and sustained droughts to impact North America in the past 1500 years. The 16th century megadrought may have persisted for up to 40 years, and extended from the tropics to the boreal forest and from the Pacific to Atlantic coasts. Evidence for the 8th century drought is sparse, but tree-ring and lake sediment data indicate that this drought extended from the northern Great Plains, across the southwestern United States, and into central Mexico and the Yucatan peninsula. Tree-ring data from Colorado and New Mexico document severe drought from A.D. 735-765, and may provide accurate and precise dating for the onset of the epic droughts reconstructed during the late first millennium A.D. with sedimentary data from Elk Lake, Minnesota; Moon Lake, South Dakota; La Piscina de Yuriria, Guanajuato; and Lake Chichancanab, Yucatan. If these chronological refinements are correct, then the sedimentary records suggest much greater persistence to the 8th century megadrought than indicated by the very high resolution tree-ring data, and a strong second pulse of prolonged drought late in the first millennium. Analyses of instrumental precipitation and drought indices during the 20th century, along with tree-ring reconstructions of climate in Mexico and the Southwest, indicate that annual and decadal droughts can both simultaneously impact the entire region from New Mexico and Texas down into central Mexico. The intensity and large-scale impact of drought across this region seem to be greatest when La Nina conditions and the low phase of the North Pacific oscillation prevail. The tree-ring dated 8th century megadrought occurred near the decline of the Classic Period civilizations at Teotihuacan in central Mexico and in the Mayan region of the Yucatan. The 8th century megadrought may have interacted with anthropogenic environmental degradation, epidemic disease, and social upheaval to

This paper presents observations acquired in southern Greece and their analyses. Over 1500 timings sent to the European Southern Observatory by observers world-wide resulted in a determination of the Astronomical Unit to within about 0.04% of the currently accepted value. These observations were supported by funds provided by the Denison University Research Foundation

    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.

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

    2013-01-01

    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.

    2010-01-01

    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.

    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

    2001-04-01

    As the need for technical talent grows, the number of young women pursuing technical degrees in the US is declining in spite of the fact that the number of young women earning degrees is at a record high. The attitudes of young people towards math and science are formed very early, and are strongly influenced by their personal experiences. The recommended science and math curricula for elementary education strongly encourage the use of hands-on experiences, coupled with linking the concepts being studied to real world situations, in an effort to overcome the perception that science is for the "brainy". Data indicates that this alone is insufficient for young women to overcome the widely held stereotypical view that science and technology are strictly white male domains. IBM created an initiative to reach out to middle school young women who have the potential to become scientists and engineers. The Technology Camp for Young Women was designed to provide a challenging, hands-on exposure to science, engineering and applied mathematics in a supportive environment. IBM scientists and engineers led the sessions and also serve as mentors during the school year. The program significantly improved the perceptions of the young women toward technical fields of study.

  8. 8th International Special Session on Current Trends in Numerical Simulation for Parallel Engineering Environments

    In today's world, the use of parallel programming and architectures is essential for simulating practical problems in engineering and related disciplines. Significant progress in CPU architecture (multi- and many-core CPUs, SMT, transactional memory, virtualization support, shared caches etc.) system scalability, and interconnect technology, continues to provide new opportunities, as well as new challenges for both system architects and software developers. These trends are paralleled by progress in algorithms, simulation techniques, and software integration from multiple disciplines. In its 8th year, ParSim continues to build a bridge between application disciplines and computer science and to help fostering closer cooperations between these fields. Since its successful introduction in 2002, ParSim has established itself as an integral part of the EuroPVM/MPI conference series. In contrast to traditional conferences, emphasis is put on the presentation of up-to-date results with a short turn-around time. We believe that this offers a unique opportunity to present new aspects in this dynamic field and discuss them with a wide, interdisciplinary audience. The EuroPVM/MPI conference series, as one of the prime events in parallel computation, serves as an ideal surrounding for ParSim. This combination enables participants to present and discuss their work within the scope of both the session and the host conference. This year, five papers from authors in five countries were submitted to Par-Sim, and we selected three of them. They cover a range of different application fields including mechanical engineering, material science, and structural engineering simulations. We are confident that this resulted in an attractive special session and that this will be an informal setting for lively discussions as well as for fostering new collaborations. Several people contributed to this event. Thanks go to Jack Dongarra, the EuroPVM/MPI general chair, and to Jan Westerholm, Juha

  9. Collecting behavioural data using the world wide web: considerations for researchers

    2003-01-01

    Objective: To identify and describe advantages, challenges, and ethical considerations of web based behavioural data collection. Methods: 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. Results: 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. Conclusions: 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. PMID:12490652

    This issue of Journal of Physics: Conference Series contains contributed papers presented at the 8th European Conference on Applied Superconductivity (EUCAS'07) that was held in Brussels, Belgium from 16-20 September 2007. The plenary and invited papers were published in the journal Superconductor Science and Technology. The scientific aims of EUCAS'07 followed the tradition established at the preceding conferences in Göttingen (Germany), Edinburgh (United Kingdom), Eindhoven (The Netherlands), Sitges (Spain), Lyngby (Denmark), Sorrento (Italy) and Vienna (Austria). The focus was placed on the interplay between the most recent developments in superconductor research and the positioning of applications of superconductivity in the marketplace. Although initially founded as an exchange forum mainly for European scientists, it has gradually developed into a truly international meeting with a very significant attendance from the Far East and the United States. Under the guidance of ESAS (the European Society for Applied Superconductivity) this Brussels conference was jointly organized by the University of Ghent and the University of Liege and attracted 795 participants to the scientific programme including a healthy number of 173 students. Participants from 46 countries included a considerable 30% attendance from the Far East and 7% from the United States and Canada. Thirty companies presented their latest developments in the field; 13 plenary and 28 invited lectures highlighted the state-of-the-art in the areas of materials, large-scale as well as small-scale applications were given. Based on a refereed evaluation of all the papers and posters submitted, 347 papers were selected for publication in the IOP electronic journal Journal of Physics: Conference Series and in Superconductor Science and Technology. EUCAS'07 spread a lot of optimism and enthusiasm for this fascinating field of research and for its well established technological potential, especially among the

    These proceedings arose from the 8th Asian International Seminar on Atomic and Molecular Physics (AISAMP) which was held at the University of Western Australia 24-28 November 2008. The history of AISAMP (Takayanagi and Matsuzawa 2002) recognizes its origin from the Japan-China meeting of 1985, and the first use of the name 'The First Asian International Seminar on Atomic and Molecular Physics (AISAMP)' in 1992. The initial attendees, Japan and China, were joined subsequently by scientists from Korea, Taiwan, India, Australia and recently by Malaysia, Thailand, Vietnam, Turkey Iran, UK and USA. The main purpose of the biennial AISAMP series is to create a wide forum for exchanging ideas and information among atomic and molecular scientists and to promote international collaboration. The scope of the AISAMP8 meeting included pure, strategic and applied research involving atomic and molecular structure and processes in all forms of matter and antimatter. For 2008 the AISAMP conference incorporated the Australian Atomic and Molecular Physics and Quantum Chemistry meeting. The topics for AISAMP8 embraced themes from earlier AISAMP meetings and reflected new interests, in atomic and molecular structures, spectroscopy and collisions; atomic and molecular physics with laser or synchrotron radiation; quantum information processing using atoms and molecules; atoms and molecules in surface physics, nanotechnology, biophysics, atmospheric physics and other interdisciplinary studies. The implementation of the AISAMP themes, as well as the international representation of research interests, is indicated both in the contents list of these published manuscripts as well as in the program for the meeting. Altogether, 184 presentations were made at the 8th AISAMP, including Invited Talks and Contributed Poster Presentations, of which 60 appear in the present Proceedings after review by expert referees in accordance with the usual practice of Journal of Physics: Conference Series of

  16. A review of images of nurses and smoking on the World Wide Web.

    PubMed

    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.

    PubMed

    Sperling, W; Biermann, T; Maler, J M

    2009-08-01

    Drastic losses on the stock markets within short periods have been the subject of numerous investigations in view of the fact that they are often irrational. In a recently published model we reported about the world-wide phenomenon of Global panic reaction (GPR) [Sperling W, Bleich S, Reulbach U. Black Monday on stock markets throughout the world - a new phenomenon of collective panic disorder? A psychiatric approach. Med Hypotheses 2008;71(6):972-4], which illustrate typical psychiatric symptoms of panic disorder. We now complete this model by a therapeutic approach for the patient. Therefore the identification of a therapeutic regime "step by step" was necessary.

    1996-12-31

    I view the World Wide Web as an information food chain. The maze of pages and hyperlinks that comprise the Web are at the very bottom of the chain. The WebCrawlers and Alta Vistas of the world are information herbivores; they graze on Web pages and regurgitate them as searchable indices. Today, most Web users feed near the bottom of the information food chain, but the time is ripe to move up. Since 1991, we have been building information carnivores, which intelligently hunt and feast on herbivores in Unix, on the Internet, and on the Web.

  19. PREFACE: 8th Edoardo Amaldi Conference on Gravitational Waves

    NASA Astrophysics Data System (ADS)

    Marka, Zsuzsa; Marka, Szabolcs

    2010-04-01

    (The attached PDF contains select pictures from the Amaldi8 Conference) At Amaldi7 in Sydney in 2007 the Gravitational Wave International Committee (GWIC), which oversees the Amaldi meetings, decided to hold the 8th Edoardo Amaldi Conference on Gravitational Waves at Columbia University in the City of New York. With this decision, Amaldi returned to North America after a decade. The previous two years have seen many advances in the field of gravitational wave detection. By the summer of 2009 the km-scale ground based interferometric detectors in the US and Europe were preparing for a second long-term scientific run as a worldwide detector network. The advanced or second generation detectors had well-developed plans and were ready for the production phase or started construction. The European-American space mission, LISA Pathfinder, was progressing towards deployment in the foreseeable future and it is expected to pave the ground towards gravitational wave detection in the milliHertz regime with LISA. Plans were developed for an additional gravitational wave detector in Australia and in Japan (in this case underground) to extend the worldwide network of detectors for the advanced detector era. Japanese colleagues also presented plans for a space mission, DECIGO, that would bridge the gap between the LISA and ground-based interferometer frequency range. Compared to previous Amaldi meetings, Amaldi8 had new elements representing emerging trends in the field. For example, with the inclusion of pulsar timing collaborations to the GWIC, gravitational wave detection using pulsar timing arrays was recognized as one of the prominent directions in the field and was represented at Amaldi8 as a separate session. By 2009, searches for gravitational waves based on external triggers received from electromagnetic observations were already producing significant scientific results and plans existed for pointing telescopes by utilizing gravitational wave trigger events.

  4. The World-Wide Web: an interface between research and teaching in bioinformatics.

    PubMed

    Aiton, J F

    1994-10-01

    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 archives that 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.

  6. Technical Considerations in Remote LIMS Access via the World Wide Web

    PubMed Central

    Schlabach, David M.

    2005-01-01

    The increased dependency on the World Wide Web by both laboratories and their customers has led LIMS developers to take advantage of thin-client web applications that provide both remote data entry and manipulation, along with remote reporting functionality. Use of an LIMS through a web browser allows a person to interact with a distant application, providing both remote administration and real-time analytical result delivery from virtually anywhere in the world. While there are many benefits of web-based LIMS applications, some concern must be given to these new methods of system architecture before justifying them as a suitable replacement for their traditional client-server systems. Developers and consumers alike must consider the security aspects of introducing a wide area network capable system into a production environment, as well as the concerns of data integrity and usability.

  7. CliniWeb: managing clinical information on the World Wide Web.

    PubMed Central

    Hersh, W R; Brown, K E; Donohoe, L C; Campbell, E M; Horacek, A E

    1996-01-01

    The World Wide Web is a powerful new way to deliver on-line clinical information, but several problems limit its value to health care professionals: content is highly distributed and difficult to find, clinical information is not separated from non-clinical information, and the current Web technology is unable to support some advanced retrieval capabilities. A system called CliniWeb has been developed to address these problems. CliniWeb is an index to clinical information on the World Wide Web, providing a browsing and searching interface to clinical content at the level of the health care student or provider. Its database contains a list of clinical information resources on the Web that are indexed by terms from the Medical Subject Headings disease tree and retrieved with the assistance of SAPHIRE. Limitations of the processes used to build the database are discussed, together with directions for future research. PMID:8816350

    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.

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

    NASA Technical Reports Server (NTRS)

    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.

  17. Curvature of co-links uncovers hidden thematic layers in the World Wide Web

    PubMed Central

    Eckmann, Jean-Pierre; Moses, Elisha

    2002-01-01

    Beyond the information stored in pages of the World Wide Web, novel types of “meta-information” are created when pages connect to each other. Such meta-information is a collective effect of independent agents writing and linking pages, hidden from the casual user. Accessing it and understanding the interrelation between connectivity and content in the World Wide Web is a challenging problem [Botafogo, R. A. & Shneiderman, B. (1991) in Proceedings of Hypertext (Assoc. Comput. Mach., New York), pp. 63–77 and Albert, R. & Barabási, A.-L. (2002) Rev. Mod. Phys. 74, 47–97]. We demonstrate here how thematic relationships can be located precisely by looking only at the graph of hyperlinks, gleaning content and context from the Web without having to read what is in the pages. We begin by noting that reciprocal links (co-links) between pages signal a mutual recognition of authors and then focus on triangles containing such links, because triangles indicate a transitive relation. The importance of triangles is quantified by the clustering coefficient [Watts, D. J. & Strogatz, S. H. (1999) Nature (London) 393, 440–442], which we interpret as a curvature [Bridson, M. R. & Haefliger, A. (1999) Metric Spaces of Non-Positive Curvature (Springer, Berlin)]. This curvature defines a World Wide Web landscape whose connected regions of high curvature characterize a common topic. We show experimentally that reciprocity and curvature, when combined, accurately capture this meta-information for a wide variety of topics. As an example of future directions we analyze the neural network of Caenorhabditis elegans, using the same methods. PMID:11972019

The importance of triangles is quantified by the clustering coefficient [Watts, D. J. & Strogatz, S. H. (1999) Nature (London) 393, 440-442], which we interpret as a curvature [Bridson, M. R. & Haefliger, A. (1999) Metric Spaces of Non-Positive Curvature (Springer, Berlin)]. This curvature defines a World Wide Web landscape whose connected regions of high curvature characterize a common topic. We show experimentally that reciprocity and curvature, when combined, accurately capture this meta-information for a wide variety of topics. As an example of future directions we analyze the neural network of Caenorhabditis elegans, using the same methods.

    Beyond the information stored in pages of the World Wide Web, novel types of "meta-information" are created when pages connect to each other. Such meta-information is a collective effect of independent agents writing and linking pages, hidden from the casual user. Accessing it and understanding the interrelation between connectivity and content in the World Wide Web is a challenging problem [Botafogo, R. A. & Shneiderman, B. (1991) in Proceedings of Hypertext (Assoc. Comput. Mach., New York), pp. 63-77 and Albert, R. & Barabási, A.-L. (2002) Rev. Mod. Phys. 74, 47-97]. We demonstrate here how thematic relationships can be located precisely by looking only at the graph of hyperlinks, gleaning content and context from the Web without having to read what is in the pages.

    Many countries, including the United States, Canada, European Union member states, and others, require that a comprehensive search for possible alternatives be completed before beginning some or all research involving animals. Completing comprehensive alternatives searches and keeping current with information associated with alternatives to animal testing is a challenge that will be made easier as people throughout the world gain access to the Internet and World Wide Web. Numerous Internet and World Wide Web resources are available to provide guidance and other information on in vitro and other alternatives to animal testing. A comprehensive Web site is Alternatives to Animal Testing on the Web (Altweb), which serves as an online clearinghouse for resources, information, and news about alternatives to animal testing. Examples of other important Web sites include the joint one for the (US) Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM) and the National Toxicology Program (NTP) Interagency Center for the Evaluation of Alternative Toxicological Methods (NICEATM) and the Norwegian Reference Centre for Laboratory Animal Science and Alternatives (The NORINA database). Internet mailing lists and online access to bulletin boards, discussion areas, newsletters, and journals are other ways to access and share information to stay current with alternatives to animal testing.

  1. Hidden Tree Structure is a Key to the Emergence of Scaling in the World Wide Web

    Preferential attachment is the most popular explanation for the emergence of scaling behavior in the World Wide Web, but this explanation has been challenged by the global information hypothesis, the existence of linear preference and the emergence of new big internet companies in the real world. We notice that most websites have an obvious feature that their pages are organized as a tree (namely hidden tree) and hence propose a new model that introduces a hidden tree structure into the Erdös—Rényi model by adding a new rule: when one node connects to another, it should also connect to all nodes in the path between these two nodes in the hidden tree. The experimental results show that the degree distribution of the generated graphs would obey power law distributions and have variable high clustering coefficients and variable small average lengths of shortest paths. The proposed model provides an alternative explanation to the emergence of scaling in the World Wide Web without the above-mentioned difficulties, and also explains the “preferential attachment" phenomenon.

    Rapid advances in information technology have dramatically transformed the world during the past several decades. Access to computers and the World Wide Web is increasingly required for education and employment, as well as for many activities of daily living. Although these changes have improved society in many respects, they present an obstacle for visually disabled patients who may have significant difficulty processing the visual cues presented by modern graphical user interfaces. This article reviews the specific barriers to computer and Web access faced by visually disabled patients, describes clinical evaluation methods, summarizes traditional low vision methods as well as newer assistive computer technologies for universal accessibility, and discusses emerging technologies and future directions in this area.

    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.

    The Complex Carbohydrate Research Center (CCRC) of the University of Georgia holds a symposium yearly that highlights a broad range of carbohydrate research topics. The 8th Annual Georgia Glycoscience Symposium entitled “Integrating Models of Plant Cell Wall Structure, Biosynthesis and Assembly” was held on April 7, 2014 at the CCRC. The focus of symposium was on the role of glycans in plant cell wall structure and synthesis. The goal was to have world leaders in conjunction with graduate students, postdoctoral fellows and research scientists to propose the newest plant cell wall models. The symposium program closely followed the DOE’s mission and was specifically designed to highlight chemical and biochemical structures and processes important for the formation and modification of renewable plant cell walls which serve as the basis for biomaterial and biofuels. The symposium was attended by both senior investigators in the field as well as students including a total attendance of 103, which included 80 faculty/research scientists, 11 graduate students and 12 Postdoctoral students.

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

    NASA Astrophysics Data System (ADS)

    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).

    The development of a hospital wide PACS is in progress at the University Hospital of Geneva and several archive modules are operational since 1992. This PACS is intended for wide distribution of images to clinical wards. As the PACS project and the number of archived images grow rapidly in the hospital, it was necessary to provide an easy, more widely accessible and convenient access to the PACS database for the clinicians in the different wards and clinical units of the hospital. An innovative solution has been developed using tools such as Netscape navigator and NCSA World Wide Web server as an alternative to conventional database query and retrieval software. These tools present the advantages of providing a user interface which is the same, independent of the platform being used (e.g. Mac, Windows, UNIX), and an easy integration of different types of documents (e.g. text, images). A strict access control has been added to this interface. It allows user identification and access rights checking, as defined by the in-house hospital information system, before allowing the navigation through patient data records.

    Cader, Raffik; Campbell, Steve; Watson, Don

    2003-01-01

    Existing criteria used to evaluate information on the World Wide Web often are not related to nursing, especially in relation to clinical and evidence-based practice. Published criteria have been found orientated to the health-consumer, medicine, or general information. In this study, the process by which nurses evaluate practice-related information and the associated evaluative nursing criteria were investigated using a grounded theory approach. In the first stage of this ongoing investigation, semistructured interviews were used to collect data from UK postregistration nursing students. The findings from this initial study provided indications of the process and the criteria for evaluating information on the World Wide Web. Participating students identified intuition as part of the evaluative process. They identified some criteria similar to existing standards, but critically, with additional criteria that are nursing practice related. Because these new criteria are significant for evaluating nursing information, further refinement of these findings is being undertaken through the next stage of the research program.

  2. World-wide association of timberline forest advance with microsite type along a precipitation gradient

    2009-12-01

    Timberline forest advance associated with global climate change is occurring worldwide and is often associated with microsites. Microsites, controlled by topography, substrates, and plant cover, are localized regions dictating temperature, moisture, and solar radiation. These abiotic factors are integral to seedling survival. From a compilation of world-wide information on seedling regeneration on microsites at timberline, including our on-going research in the Pacific Northwest, we classified available literature into four microsite categories, related microsite category to annual precipitation, and used analysis of variance to detect statistical differences in microsite type and associated precipitation. We found statistical differences (p = 0.022) indicating the usefulness of understanding microsite/precipitation associations in detecting world-wide trends in timberline expansion. For example, wetter timberlines with downed wood, had regeneration associated with nurse logs, whereas on windy, drier landscapes, regeneration was typically associated with either leeward sides of tree clumps or on microsites protected from frost by overstory canopy. In our study of timberline expansion in the Pacific Northwest, we expect that such knowledge of microsite types associated with forest expansion will reveal a better understanding of mechanisms and rates of timberline forest advance during global warming.

    1997-04-01

    At the IST and SPIE 96 conference, the author reported a successful cooperative visualization case study that involved using an internet web-browser for data dissemination and data visualization applications between the US and Japanese offices. This cooperative visualization effort using computers and the web-browser has been evaluated, and it has pointed the way to the current research involving the use of the World Wide Web environment for real-time simulation and interactive visualization. Since the spring of 1996, the author has been using Fujitsu's new multi-processor supercomputer VPP300 for fast numerical model simulations and data generations. Meanwhile, the web technology has been advancing very quickly, and it now provides many tools and methods for the scientific visualization. In the summer of 1996, the author began to work on a prototype for a real-time supercomputing interactive visualization system based on the available World Wide Web browser tools and a Fujitsu visualization software known as VisLink. The intranet version of this system was completed in December of 1997. Design issues and a case study of the prototype will be discussed in this paper.

  5. Violent ethnic wars and world-wide people movement: implications for mental health nursing practice.

    PubMed

    Procter, N G

    1998-09-01

    In recent years, the world has been subjected to violent ethnic wars for autonomy and secession. Violent conflicts over national and international territorial boundaries are marked by a murderous mistrust, hatred and a perpetual life-and-death struggle in the present. For the mental health nurse, the world-wide persistent global circumstance of international catastrophe and increasing nationalism mediated through war is inextricably linked to practice as well as the significant health and lifestyle concerns of displaced people. Central to the discussion in this paper will be the mechanisms used by the mental health nurse to maintain empathy and clinical excellence during highly sensitive practice issues; in particular, the management of feelings of frustration, anger, guilt, loneliness and sleeplessness, and repeated mental images of suffering and human butchering, because these issues intersect with national and cultural identity. In rising to the challenges these issues present, mental health nursing must co-exist with critical world events and the globalisation of national identity in cultural diversity.

    As a consequence of the limited resources of underdeveloped countries and the limited interest of the developed ones, the assessment of the chemical quality of entire water bodies around the world is a utopia in the near future. The methodology described here may serve as a first approach for the fast identification of water bodies that do not meet the good chemical status demanded by the European Water Framework Directive (WFD). It also allows estimating the natural background (or reference values of concentration) of the areas under study using a simple criterion. The starting point is the calculation the World-Wide Natural Background Levels (WWNBLs) and World-Wide Threshold Values (WWTVs), two indexes that depend on the concentration of seven elements present in sediments. These elements, As, Cd, Cr, Cu, Ni, Pb and Zn, have been selected taking into account the recommendations of the UNEP (United Nations Environment Programme) and USEPA (United States Environmental Protection Agency), that describe them as elements of concern with respect to environmental toxicity. The methodology has been exemplified in a case study that includes 134 sediment samples collected in 11 transitional water bodies from 7 different countries and 4 different continents. Six of the water bodies considered met the good chemical status demanded by the WFD. The rest of them exceeded the reference WWTVs, at least for one of the elements. The estuaries of the Nerbioi-Ibaizabal (Basque Country) and Cavado (Portugal), the sea inlet of Río San Pedro (Spain), the Sepetiba Bay (Brazil) and the Yucateco lagoon (Mexico) belong to that group.

    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.

    The Internet and the World Wide Web (www) serve as a source of information and a communication network. Together they form a so-called web or network that allows for transmission and dissemination of information in unprecedented speed, volume and detail. This article presents an overview of the current status of neuropathology content on the www. As well as considering the Internet as a resource for neuropathology practice, education and research, we also address the issue of quality assurance when evaluating Internet and www content. Four major categories of websites (archival, broker, news and blog) are discussed and resources relevant to neuropathology of each type are highlighted. We believe that our report and similar attempts can provide an opportunity to discuss appropriate and effective use of the Internet by the neuropathology community.

    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.

    World Wide Web (Web) technology has become increasingly popular and successful, because it uses standard communication protocols and Hyper Text Markup Language(HTML), and is supported on multiple platforms. Innovations such as server push, secure socket layer and Java make it possible to use the Web as the basis for creating monitoring systems of dynamic processes. This paper presents a project, whose goal is to develop a Web based Intelligent on-line Monitoring system for Intensive Care Units (IMI). IMI has been tested and evaluated in an intensive care unit since October 1995, and the results are promising. After presenting the motivations of using Web technology, we present the system structure and the functionality of IMI as well as the testing and evaluation results. Security issues are also addressed. PMID:8947761

    As a teaching tool, the World Wide Web (WWW) is unprecedented in its ability to transmit information and enhance communication between scientist and student. Just beginning to be developed are sites that actively engage the user in the learning process and provide hands-on methods of teaching contemporary topics. These topics are often not found in the classroom due to the complexity and expense of the laboratory equipment and the WWW is an ideal tool for overcoming this difficulty. This paper presents a model for using the Internet to teach high school students about plasma physics and fusion energy. Students are given access to real-time data, virtual experiments, and communication with professional scientists via email. Preliminary data indicate that student collaboration and student-led learning is encouraged when using the site in the classroom.

    Electronic medical record systems (EMRSs) currently do not lend themselves easily to cross-institutional clinical care and research. Unique system designs coupled with a lack of standards have led to this difficulty. The authors have designed a preliminary EMRS architecture (W3-EMRS) that exploits the multiplatform, multiprotocol, client-server technology of the World Wide Web. The architecture abstracts the clinical information model and the visual presentation away from the underlying EMRS. As a result, computation upon data elements of the EMRS and their presentation are no longer tied to the underlying EMRS structures. The architecture is intended to enable implementation of programs that provide uniform access to multiple, heterogeneous legacy EMRSs. The authors have implemented an initial prototype of W3-EMRS that accesses the database of the Boston Children's Hospital Clinician's Workstation. PMID:8723610

    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.

    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.

    As a trial project, the Indiana University Department of Radiology has develop[ed a low-cost manner of distributing radiological images throughout a medical environment using the World Wide Web (WWW). The interface requires the user to have a WWW-browser client, such as Netscape, running on UNIX, PC, or Macintosh platforms. A forms-based interface allows the user to query several DICOM-capable machines at the machine, patient, study, series, and image levels. Once an image transfer is initiated, images are prewindowed from 16- to 8-bits, compressed using public domain Joint Photographic Expert Group (JPEG) compression routines, transferred to the WWW client program, and decompressed and displayed using a locally selected image viewing program. At the currently implemented level of compression (75% quality), the entire fetch-transform-JPEG-display process takes 2 to 5 seconds over Ethernet, depending on the platform used.

    The World-Wide Web offers a potentially interesting tool to collect data from a large and heterogeneous audience. While questionnaires have become rather common on the Internet, its potential reaches far beyond text processing. In principle, it is possible not only to perform interactive, dynamic experiments on the Web, but also to include graphical animation and time-critical responses, such as reaction times. We implemented a visual motion extrapolation task on the Web using the programming language Java, which can be interpreted by standard Web browsers such as Netscape or Internet Explorer. The data collected with this method turned out to be reliable and differed little from data obtained in a controlled laboratory setting, with the exception of conditions with fixation instruction. Thus, the Web can, generally speaking, be used for data collection of large sample sizes. The strengths and weaknesses of dynamic visual simulation experiments on the Internet are discussed.

    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.

    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.

    Assessment of neurocognitive functioning is a critical task in many clinical, educational, service, and industrial settings. We report on descriptive and validation data of a new, World-Wide-Web-based, comprehensive battery of neurocognitive functioning, WebNeuro, that can be used in both applied and research contexts. Fifty healthy control participants completed both WebNeuro, and an established non-Internet-based computerized cognitive assessment battery, IntegNeuro, that uses a touchscreen platform. Results indicated comparability across the two batteries, in terms of critical single test scores, factor analysis derived indices,overall performance scores, and sex differences. These results support the validity of WebNeuro as a neurocognitive assessment measure. Advantages of its use in applied and research settings are discussed.

    The genetic structure of humpback whale populations and subpopulation divisions is described by restriction fragment length analysis of the mitochondrial (mt) DNA from samples of 230 whales collected by biopsy darting in 11 seasonal habitats representing six subpopulations, or 'stocks', world-wide. The hierarchical structure of mtDNA haplotype diversity among population subdivisions is described using the analysis of molecular variance (AMOVA) procedure, the analysis of gene identity, and the genealogical relationship of haplotypes as constructed by parsimony analysis and distance clustering. These analyses revealed: (i) significant partitioning of world-wide genetic variation among oceanic populations, among subpopulations or 'stocks' within oceanic populations and among seasonal habitats within stocks; (ii) fixed categorical segregation of haplotypes on the south-eastern Alaska and central California feeding grounds of the North Pacific; (iii) support for the division of the North Pacific population into a central stock which feeds in Alaska and winters in Hawaii, and an eastern or 'American' stock which feeds along the coast of California and winters near Mexico; (iv) evidence of genetic heterogeneity within the Gulf of Maine feeding grounds and among the sampled feeding and breeding grounds of the western North Atlantic; and (v) support for the historical division between the Group IV (Western Australia) and Group V (eastern Australia, New Zealand and Tonga) stocks in the Southern Oceans. Overall, our results demonstrate a striking degree of genetic structure both within and between oceanic populations of humpback whales, despite the nearly unlimited migratory potential of this species. We suggest that the humpback whale is a suitable demographic and genetic model for the management of less tractable species of baleen whales and for the general study of gene flow among long-lived, mobile vertebrates in the marine ecosystem.

    A recent published model described the phenomenon of a global panic reaction (GPR) on the stock markets based on two remarkable stock market crashes in the months of January and March [Sperling W, Bleich S, Reulbach U, Black Monday on stock markets throughout the world - a new phenomenon of collective panic disorder? A psychiatric approach. Med Hypotheses; 2008]. This model was completed by a therapeutic approach following typical elements of cognitive behavioural therapy (CBT) [Sperling W, Biermann T, Maler JM, Global panic reaction - a therapeutic approach to a world-wide economic crisis. Med Hypotheses; 2009]. The phenomenon of a global panic reaction due to economic crises seems to have even larger implications on human health as well. It is well known that acute and chronic distress is competent to suppress the immune system by various mechanisms that are discussed in detail. This global panic reaction - that has also been observed in former times - might therefore be responsible for the new variation of recent influenza pandemic coming from Mexico.

    We present Terrestrial Gamma-ray Flash (TGF) pairs detected with the Gamma-ray Burst Monitor (GBM) on the Fermi Space Telescope and associated sferics from the World Wide Lightning Network (WWLLN). Several improvements have been made to the GBM TGF detection algorithms since launch in 2008, which have increased the rate of TGFs to ~800 a year. The improved TGF detection algorithms have also uncovered more TGFs within 200 s of each other. There are ~600 unique TGFs with a wide range of time separations. One question is whether a pair originates from the same thunderstorm or from different storms in a storm system. Detecting multiple TGFs from a single storm and their separation in time provides a measure of the electric charging timescales involved in the production of TGFs within a storm. With only gamma-ray detections, this question is difficult to answer since GBM detects TGFs up to 800 km from the nadir of Fermi. If WWLLN sferics are found for both TGFs of a pair, the improved localization uncertainty (<25km) allows us to better answer this question. We present TGF pairs that match this criteria. These pairs are temporally separated by milliseconds to ~180 s.

    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.

    We report a genus-wide comparison of venom proteome variation across New World pit vipers in the genus Agkistrodon. Despite the wide variety of habitats occupied by this genus and that all its taxa feed on diverse species of vertebrates and invertebrate prey, the venom proteomes of copperheads, cottonmouths, and cantils are remarkably similar, both in the type and relative abundance of their different toxin families. The venoms from all the eleven species and subspecies sampled showed relatively similar proteolytic and PLA2 activities. In contrast, quantitative differences were observed in hemorrhagic and myotoxic activities in mice. The highest myotoxic activity was observed with the venoms of A. b. bilineatus, followed by A. p. piscivorus, whereas the venoms of A. c. contortrix and A. p. leucostoma induced the lowest myotoxic activity. The venoms of Agkistrodon bilineatus subspecies showed the highest hemorrhagic activity and A. c. contortrix the lowest. Compositional and toxicological analyses agree with clinical observations of envenomations by Agkistrodon in the USA and Central America. A comparative analysis of Agkistrodon shows that venom divergence tracks phylogeny of this genus to a greater extent than in Sistrurus rattlesnakes, suggesting that the distinct natural histories of Agkistrodon and Sistrurus clades may have played a key role in molding the patterns of evolution of their venom protein genes. Biological significance A deep understanding of the structural and functional profiles of venoms and of the principles governing the evolution of venomous systems is a goal of venomics. Isolated proteomics analyses have been conducted on venoms from many species of vipers and pit vipers. However, making sense of these large inventories of data requires the integration of this information across multiple species to identify evolutionary and ecological trends. Our genus-wide venomics study provides a comprehensive overview of the toxic arsenal across

    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

    We report results from an NSF-funded project to build, test, and research the impact of a WorldWide Telescope Visualization Lab (WWT Vizlab), meant to offer learners a deeper physical understanding of the causes of the Moon’s phases and eclipses. The Moon Phases VizLab is designed to promote accurate visualization of the complex, 3-dimensional Earth-Sun-Moon relationships required to understand the Moon’s phases, while also providing opportunities for middle school students to practice critical science skills, like using models, making predictions and observations, and linking them in evidence-based explanations. In the Moon Phases VizLab, students use both computer-based models and lamp + ball physical models. The VizLab emphasizes the use of different scales in models, why some models are to scale and some are not, and how choices we make in a model can sometimes inadvertently lead to misconceptions. For example, textbook images almost always depict the Earth and Moon as being vastly too close together, and this contributes to the common misconception that the Moon’s phases are caused by the Earth’s shadow. We tested the Moon Phases VizLab in two separate phases. In Phase 1 (fall 2012), we compared learning gains from the WorldWide Telescope (WWT) VizLab with a traditional 2-dimensional Moon phases simulator. Students in this study who used WWT had overall higher learning gains than students who used the traditional 2D simulator, and demonstrated greater enthusiasm for using the virtual model than students who used the 2D simulator. In Phase 2 (spring 2013), all students in the study used WWT for the virtual model, but we experimented with different sequencing of physical and virtual models in the classroom. We found that students who began the unit with higher prior knowledge of Moon phases (based on the pre-unit assessment) had overall higher learning gains when they used the virtual model first, followed by the physical model, while students who had

    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

    2010-12-01

    Upward advance of timberlines, associated with climate warming, is occurring in the Pacific Northwest (PNW) as well as many other mountainous regions of the world. Examination of seedling establishment and survival of sensitive seedlings, rather than examination of older resilient trees, may give a clearer understanding of current climatic factors affecting potential expansion of timberline. Our investigation of seedling establishment along timberline edges in the PNW indicates that trees often germinate on small landforms known as microsites. Microsites include small convexities or concavities on the soil surface having a scale of centimeters to meters, but also include associations with slope, aspect, rocks or plants, or substrates dominated by mineral soil or wood. Growing on favorable microsites helps seedlings cope with some of the stresses that exist at high elevation sites including wind, cold temperatures, high radiation, drought, animal predation, and infestation by fungal pathogens found in snow and soil. Microsites, by providing warmer substrates, adequate moisture, and shelter, allow plants to function more affectively in mountain environments. Our summary of microsite type and associated timberline advance in a world-wide context indicates that factors such as snow accumulation, summer rainfall, and availability of microsites, will control timberline advance. In windswept timberline locations, rocks and plants provide shelter from wind and reduce the likelihood of night frost. In arid climates, concave microsites aid in snow deposition providing needed moisture to seedlings during periods of drought. In contrast, convex microsites and wood substrates, typical sites of regeneration in the PNW where precipitation typically exceeds 150 cm per year, facilitate early snow melt, thereby increasing growing season. Large trees at the edge of timberline fall into alpine meadows, decay, and provide sites for seedling establishment. These sites commonly called

    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.

    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.

    As the World Wide Web has become more prominent as a mode of communication, it has opened up new possibilities for research data collection. This article identifies measurement issues that occur with Internet data collection that are relevant to qualitative and quantitative research approaches as they occurred in a triangulated Internet study of perimenopausal women with migraine headaches. Issues associated with quantitative data collection over the Internet include (a) selecting and designing Internet data collection protocols that adequately address study aims while also taking advantage of the Internet, (b) ensuring the reliability and validity of Internet data collected, (c) adapting quantitative paper-and-pencil data collection protocols for the Internet, (d) making Internet data collection practical for respondents and researchers, and (e) ensuring the quality of quantitative data collected. Qualitative data collection over the Internet needs to remain true to the philosophical stance of the qualitative approach selected. Researcher expertise in qualitative data collection must be combined with expertise in computer technology and information services if data are to be of ultimate quality The advantages and limitations of collecting qualitative data in real time or at a later time are explored, as well as approaches to enhance qualitative data collection over the Internet. It was concluded that like any research approach or method, Internet data collection requires considerable creativity, expertise, and planning to take advantage of the technology for the collection of reliable and valid research data.

  16. Alaskan Auroral All-Sky Images on the World Wide Web

    1997-01-01

    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.

    As part of the required curriculum for medical students, we devised a literature-searching practicum that has been used for two years. In both years, we stressed going beyond the skills needed for using a particular searching program, towards a more conceptual approach to information searching. In the first year, the practicum was taught in a traditional lecture/hands-on format. In the second year, the lecture was replaced by a World Wide Web-based tutorial (http:@www.welch.jhu.edu/Education/tutorials/pra cticum.html). To our knowledge, this is the first Web-based resource intended to teach students about appropriate use of search technology. Comparison of student evaluations showed no difference in attitude toward the two versions of the practicum, and observation of student performance suggested similar levels of proficiency. We conclude that placing these educational materials on the Web (1) makes us practice what we preach; (2) is as effective as traditional teaching methods; and (3) gives students a resource for reinforcement learning.

    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.

    1998-06-01

    The objective of the medical teleconsultation system presented in this paper is to demonstrate the use of the World Wide Web (WWW) for telemedicine and interactive medical information exchange. The system, which is developed based on Java, could provide several basic Java tools to fulfill the requirements of medical applications, including a file manager, data tool, bulletin board, and digital audio tool. The digital audio tool uses point-to-point structure to enable two physicians to communicate directly through voice. The others use multipoint structure. The file manager manages the medical images stored in the WWW information server, which come from a hospital database. The data tool supports cooperative operations on the medical data between the participating physicians. The bulletin board enables the users to discuss special cases by writing text on the board, send their personal or group diagnostic reports on the cases, and reorganize the reports and store them in its report file for later use. The system provides a hardware-independent platform for physicians to interact with one another as well as to access medical information over the WWW.

    1997-01-01

    This article propose a way to automatically retrieve images from the world-wide-web using a semantic description for images and an agent concept for the retrieval of images. The system represents image in a textual way, e.g. look for a portrait of the a specific person, or fetch an image showing a countryside in Southern California. This textual descriptions are fed in search machines, e.g. yahoo, alta- vista. The resulting html documents are seeked for links. The next step subsequently processes each link by fetching the document other the net, converting it to an ascii representation, and performing a full text search by using the image description. This leads to starting points of images which are retrieved via a web-agent. The image descriptions are decomposed in a set of parts containing image operations which are further processed, e.g. a set for representing the background of a portrait tries to find a homogeneous region in the image because this is likely to find in a portrait. Additional operations are performed on the foreground, i.e. the image region which contains e.g. the face of a person. The system is realized using two C++ libraries: one for building up web-agents, LIWA++, and one for processing images, HORUS.

    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.

    Few studies have examined systematic relationships of right whales (Eubalaena spp.) since the original species descriptions, even though they are one of the most endangered large whales. Little morphological evidence exists to support the current species designations for Eubalaena glacialis in the northern hemisphere and E. australis in the southern hemisphere. Differences in migratory behaviour or antitropical distribution between right whales in each hemisphere are considered a barrier to gene flow and maintain the current species distinctions and geographical populations. However, these distinctions between populations have remained controversial and no study has included an analysis of all right whales from the three major ocean basins. To address issues of genetic differentiation and relationships among right whales, we have compiled a database of mitochondrial DNA control region sequences from right whales representing populations in all three ocean basins that consist of: western North Atlantic E. glacialis, multiple geographically distributed populations of E. australis and the first molecular analysis of historical and recent samples of E. glacialis from the western and eastern North Pacific Ocean. Diagnostic characters, as well as phylogenetic and phylogeographic analyses, support the possibility that three distinct maternal lineages exist in right whales, with North Pacific E. glacialis being more closely related to E. australis than to North Atlantic E. glacialis. Our genetic results provide unequivocal character support for the two usually recognized species and a third distinct genetic lineage in the North Pacific under the Phylogenetic Species Concept, as well as levels of genetic diversity among right whales world-wide.

    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 .

    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.

  5. Internet as clinical information system: application development using the World Wide Web.

    1995-01-01

    Clinical computing application development at Columbia-Presbyterian Medical Center has been limited by the lack of a flexible programming environment that supports multiple client user platforms. The World Wide Web offers a potential solution, with its multifunction servers, multiplatform clients, and use of standard protocols for displaying information. The authors are now using the Web, coupled with their own local clinical data server and vocabulary server, to carry out rapid prototype development of clinical information systems. They have developed one such prototype system that can be run on most popular computing platforms from anywhere on the Internet. The Web paradigm allows easy integration of clinical information with other local and Internet-based information sources. The Web also simplifies many aspects of application design; for example, it includes facilities for the use of encryption to meet the authors' security and confidentiality requirements. The prototype currently runs on only the Web server in the Department of Medical Informatics at Columbia University, but it could be run on other Web servers that access the authors' clinical data and vocabulary servers. It could also be adapted to access clinical information from other systems with similar server capabilities. This approach may be adaptable for use in developing institution-independent standards for data and application sharing. PMID:7496876

    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

    Peterson, Jon; Hutt, Charles R.

    1982-01-01

    BACKGROUND 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 hoc 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

    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).

Although web sites containing online psychology demonstrations and experiments for non-handicapped individuals have appeared in recent years (especially in the areas of cognitive and social psychology), there appear to have been few attempts to conduct online experimentation with special populations. We recently completed two online pilot studies of families with Down syndrome or Williams syndrome members: a) A survey that asks (via Likert rating scales, adjective checklists, multiple-choice style questions, and text-entry boxes) about family background, computer use, and temperament of the special needs family member; and b) An experiment (completed by an individual with special needs) that includes auditory and visual digit span tasks and a memory-for-orientation task in which responses are entered via mouse clicks. Recruiting began with e-mail announcements to representative Down syndrome and Williams syndrome discussion groups, listserves, and bulletin boards, and submission of the project's URL (http://www.cofc.edu/~marcellm/testaw.htm) and key indexing terms to selected search engines. This paper reviews technical aspects of developing the online programmes as well as the strengths and weaknesses of online vs. traditional laboratory-based research in relation to issues such as experimental control, delivery of instructions, experimenter bias, participant recruitment, sample heterogeneity, generalization, attrition, privacy, financial costs, data integrity, and ethics. We conclude by offering our thoughts on two ways of implementing online experimentation with special populations: a) Using a remote parent 'helper' as a proxy to work with the target individual; and b) Collaborating with professional colleagues in Web-based projects conducted in traditional laboratory settings.

    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.

  7. Global Cooling: Increasing World-Wide Urban Albedos to Offset CO2

    Modification of urban albedos reduces summertime urban temperatures, resulting in a better urban air quality and building air-conditioning savings. Furthermore, increasing urban albedos has the added benefit of reflecting some of the incoming global solar radiation and countering to some extent the effects of global warming. In many urban areas, pavements and roofs constitute over 60% of urban surfaces (roof 20-25%, pavements about 40%). Using reflective materials, both roof and the pavement albedos can be increased by about 0.25 and 0.10, respectively, resulting in a net albedo increase for urban areas of about 0.1. Many studies have demonstrated building cooling-energy savings in excess of 20% upon raising roof reflectivity from an existing 10-20% to about 60% (a U.S. potential savings in excess of $1 billion (B) per year in net annual energy bills). On a global basis, our preliminary estimate is that increasing the world-wide albedos of urban roofs and paved surfaces will induce a negative radiative forcing on the earth equivalent to removing {approx} 22-40 Gt of CO{sub 2} from the atmosphere. Since, 55% of the emitted CO{sub 2} remains in the atmosphere, removal of 22-40 Gt of CO{sub 2} from the atmosphere is equivalent to reducing global CO{sub 2} emissions by 40-73 Gt. At {approx} $25/tonne of CO{sub 2}, a 40-73 Gt CO{sub 2} emission reduction from changing the albedo of roofs and paved surfaces is worth about $1,000B to 1800B. These estimated savings are dependent on assumptions used in this study, but nevertheless demonstrate considerable benefits that may be obtained from cooler roofs and pavements.

    The purpose of this paper is to facilitate international research of medical resources on the World Wide Web. International research consists of overcoming a unique set of obstacles and challenges that are not involved when undertaking research tasks using only U.S.-based information. Utilizing the World Wide Web can help us to overcome most of the restraints we would have to face when we perform research outside of our local geography. Currently, there are a number of Internet Web sites that may assist us in breaking down the barriers to undertaking international research.

  9. 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

    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

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

    1998-01-01

    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

    signals is a fundamental advantage of isotopomer ratios (Augusti et al., Chem. Geol 2008). These results demonstrate that increasing [CO2] has reduced the ratio of photorespiration to photosynthesis on a global scale. Photorespiration is a side reaction that decreases the C gain of plants; the suppression of photorespiration in all analyzed trees indicates that increasing atmospheric [CO2] is enhancing the photosynthetic efficiency of trees world-wide. The consensus response of the trees agrees with the response of annual plants in greenhouse experiments, with three important conclusions. First, the generality of the isotopomer shift confirms that the CO2 response reflects the ratio of photosynthesis to photorespiration, and that it creates a robust signal in tree rings. Second, the agreement between greenhouse-grown plants and trees indicates that there has not been an acclimation response of the trees during the past centuries. Third, the results show that the regulation of tree gas exchange has during past centuries been governed by the same rules as observed in manipulative experiments, in contradiction to recent reports (Keenan et al., Nature 2013).

    A gap-free, world-wide, ocean-, atmosphere-, and land surface-spanning geophysical data-set of three decades time-duration containing the full set of geophysical parameters characterizing global weather is the scientific perquisite for defining the climate; the generally-accepted definition in the meteorological community is that climate is the 30-year running-average of weather. Until such a tridecadal climate baseline exists, climate change discussions inevitably will have a semi-speculative, vs. a purely scientific, character, as the baseline against which changes are referenced will at least somewhat uncertain.

    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

    2015-01-01

    IC3DDose 2014, the 8th International Conference on 3D Radiation Dosimetry was held in Ystad, Sweden, from 4-7 September 2014. This grew out of the DosGel series, which began as DosGel99, the 1st International Workshop on Radiation Therapy Gel Dosimetry in Lexington, Kentucky. Since 1999 subsequent DoSGel conferences were held in Brisbane, Australia (2001), Ghent, Belgium (2004), Sherbrooke, Canada (2006) and Crete, Greece (2008). In 2010 the conference was held on Hilton Head Island, South Carolina and underwent a name-change to IC3DDose. The 7th and last meeting was held in Sydney, Australia from 4-8 November 2012. It is worth remembering that the conference series started at the very beginning of the intensity modulated radiotherapy era and that the dosimeters being developed then were, to some extent, ahead of the clinical need of radiotherapy. However, since then the technical developments in radiation therapy have been dramatic, with dynamic treatments, including tracking, gating and volumetric modulated arc therapy, widely introduced in the clinic with the need for 3D dosimetry thus endless. This was also reflected by the contributions at the meeting in Ystad. Accordingly the scope of the meeting has also broadened to IC3DDOSE - I See Three-Dimensional Dose. A multitude of dosimetry techniques and radiation detectors are now represented, all with the common denominator: three-dimensional or 3D. Additionally, quality assurance (QA) procedures and other aspects of clinical dosimetry are represented. The implementation of new dosimetric techniques in radiotherapy is a process that needs every kind of caution, carefulness and thorough validation. Therefore, the clinical needs, reformulated as the aims for IC3DDOSE - I See Three-Dimensional Dose, are: • Enhance the quality and accuracy of radiation therapy treatments through improved clinical dosimetry. • Investigate and understand the dosimetric challenges of modern radiation treatment techniques. • Provide

    Stevens, Karen E.; Stevens, Richard E.

    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

  7. "Choking game" awareness and participation among 8th graders--Oregon, 2008.

    PubMed

    2010-01-15

    The "choking game" is an activity in which persons strangulate themselves to achieve euphoria through brief hypoxia. It is differentiated from autoerotic asphyxiation. The activity can cause long-term disability and death among youths. In 2008, CDC reported 82 deaths attributed to the choking game and other strangulation activities during the period 1995-2007; most victims were adolescent males aged 11-16 years. To assess the awareness and prevalence of this behavior among 8th graders in Oregon, the Oregon Public Health Division added a question to the 2008 Oregon Healthy Teens survey concerning familiarity with and participation in this activity. This report describes the results of that survey, which indicated that 36.2% of 8th-grade respondents had heard of the choking game, 30.4% had heard of someone participating, and 5.7% had participated themselves. Youths in rural areas were significantly more likely (6.7%) to have participated than youths in urban areas (4.9%). Choking game participation was higher among 8th graders who reported mental health risk factors (4.0%), substance use (7.9%), or both (15.8%), compared with those who reported neither (1.7%). Public health surveillance of these strangulation activities among youths should be expanded to better quantify the risks and understand the motives and circumstances surrounding participation. Parents, educators, counselors, and others who work with youths should be aware of strangulation activities and their serious health effects; they should watch for signs of participation in strangulation activities, especially among youths with suspected substance use or mental health risk factors.

  10. Possible world-wide middle miocene iridium anomaly and its relationship to periodicity of impacts and extinctions

    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.

  11. Singapore National Medical Image Resource Centre (SN.MIRC): a world wide web resource for radiology education.

    2006-08-01

    Radiology education is heavily dependent on visual images, and case-based teaching files comprising medical images can be an important tool for teaching diagnostic radiology. Currently, hardcopy film is being rapidly replaced by digital radiological images in teaching hospitals, and an electronic teaching file (ETF) library would be desirable. Furthermore, a repository of ETFs deployed on the World Wide Web has the potential for e-learning applications to benefit a larger community of learners. In this paper, we describe a Singapore National Medical Image Resource Centre (SN.MIRC) that can serve as a World Wide Web resource for teaching diagnostic radiology. On SN.MIRC, ETFs can be created using a variety of mechanisms including file upload and online form-filling, and users can search for cases using the Medical Image Resource Center (MIRC) query schema developed by the Radiological Society of North America (RSNA). The system can be improved with future enhancements, including multimedia interactive teaching files and distance learning for continuing professional development. However, significant challenges exist when exploring the potential of using the World Wide Web for radiology education.

    The energy systems we have enjoyed for the last 100 years has resulted in the advanced standard of living in the developed world and a major emerging problem with climate change. Now we face a simultaneous realization that our reliance on fossil fuels is a source of conflict and economic disruption as well as causing potentially catastrophic global climate change. It is time to give serious thought to how to collectively solve this problem. Collective action is critical since individual effort by one or only a few nations cannot adequately address the issue.

    The aim of this study is to determine how the TIMSS mathematics success of the 8th grade students differentiates according to the school type, gender, mathematics report mark, parents' education level, cognitive domains and cognitive domains by gender. Relational survey method was used in the study. Six-hundred fifty two 8th grade students studying in the same city in Turkey participated in this study. In this study, a 45 question test that was made up by choosing TIMSS 2011 mathematics questionnaire was used as a data collection tool. Quantitative data analysis methods were used in the data analysis, frequency, percentage, average, standard deviation, independent sample test, one-way analysis of variance and post-hoc tests were applied to data by using SPSS packaged software. At the end of the study, it was determined that the school type, mathematics school mark, parents' education level and cognitive domains influenced the students' TIMSS mathematics success but their gender was a neutral element. Moreover, it was seen that schools which are really successful in national exams are more successful in TIMSS exam; students whose mathematics school marks are 5 and whose parents graduated from university are more successful in TIMSS exams than others. This study was produced from Alper HANCİ's master thesis that is made consulting Asst. Prof. Gül KALELİ YILMAZ.

  17. Middle school science curriculum design and 8th grade student achievement in Massachusetts public schools

    NASA Astrophysics Data System (ADS)

    Clifford, Betsey A.

    The Massachusetts Department of Elementary and Secondary Education (DESE) released proposed Science and Technology/Engineering standards in 2013 outlining the concepts that should be taught at each grade level. Previously, standards were in grade spans and each district determined the method of implementation. There are two different methods used teaching middle school science: integrated and discipline-based. In the proposed standards, the Massachusetts DESE uses grade-by-grade standards using an integrated approach. It was not known if there is a statistically significant difference in student achievement on the 8th grade science MCAS assessment for students taught with an integrated or discipline-based approach. The results on the 8th grade science MCAS test from six public school districts from 2010 -- 2013 were collected and analyzed. The methodology used was quantitative. Results of an ANOVA showed that there was no statistically significant difference in overall student achievement between the two curriculum models. Furthermore, there was no statistically significant difference for the various domains: Earth and Space Science, Life Science, Physical Science, and Technology/Engineering. This information is useful for districts hesitant to make the change from a discipline-based approach to an integrated approach. More research should be conducted on this topic with a larger sample size to better support the results.

  19. Pseudo-random Spray Release to Measure World-wide Transfer Functions of Cloud Albedo Control.

    Institute for Energy Systems, School of Engineering, University of Edinburgh. S.Salter@ed.ac.uk Previous climate models of Latham's proposal to reverse global warming by using sub-micron sea spray to increase cloud albedo have used a variety of spray patterns. Kettles forced CCN concentration to be 375/cm3 everywhere. Rasch et al used the 20% and 70% most susceptible regions. Bala and Caldeira used an even spread. Jones et al. concentrated spray in the 3.3% oceans with the highest susceptibility All used the same rate through the year. We want to choose a scheme for a climate-modelling experiment designed to identify simultaneously the effects of cloud albedo control at various seasons of the year from spray at all regions of the world on climates of all other regions the world. In particular we want to know seasons and spray places which might have an undesirable effect on precipitation. The spray systems in various regions of a numerical climate model will be modulated on an off with different but known pseudo-random sequences and a selection of seasons. The mean value of the resulting weather records of the parameters of interest, mainly temperature and water run-off, at each region will be subtracted from each value of the record so as to give just the alternating component with an average value of zero. This will be correlated with each of the chosen pseudo-random sequences to give the magnitude and polarity of the effect of a treatment at each input area and selected seasons of the year with the resulting effects on all regions. By doing a time-shifted correlation we can account for phase-shift and time delay. The signal-to-noise ratio should improve with the square root of the analysis time and so we may be able to measure the transfer function with quite a small stimulus. The results of a Mathcad simulation of the process with statistical distributions approximating to natural variations temperature and precipitation show that a single run of a climate

    2015-01-01

    Applying distance-to-frontier analysis, we have used 2.9 million patents and population data to assess whether the relative capacity of world countries and major regions to create new knowledge and technology has become globally more equal or less equal between 1990 and 2010. We show with the Gini coefficient that the global distribution of inventors has become more equal between major countries and regions. However, this trend has been largely due to the improved performance of only two major countries, China and India. The worst performing regions, totalling a population of almost 2 billion, are actually falling behind. Our results suggest that substantial parts of the global population have fallen further behind countries at the global frontier in their ability to create new knowledge and inventions, and that the catch-up among the least developed and middle-income countries is highly uneven, prompting questions about the nature and future of the global knowledge economy.

    2011-01-01

    The extraordinary progress in the knowledge of infectious disease, the discovery of antibiotics and effective vaccines are among the great achievement of the nineteenth and twentieth centuries. These achievement have led to a dramatic reduction in the levels of mortality from these diseases. According to the World Health Organization, the term "re-emerging infectious diseases" refers to infectious diseases, which although well known, have not been of recent public health importance. However, climate change, migration, changes in health services, antibiotic resistance, population increase, international travel, the increase in the number of immune-depressed patients ,etc have lead to the re-emergence of these diseases. The climate changes are exposing sectors of the population to inadequate fresh air, water, food and resources for survival which, in consequence, provoke increases in both internal and international migration. In this particular period in which we find ourselves, characterized by globalization, the international community has become aware that the re-emergence of these diseases poses an important risk for public health underlines the necessity to adopt appropriate strategies for their prevention and control. The re-emerging diseases of the twenty-first century are a serious problem for public health and even though there has been enormous progress in medical science and in the battle against infectious diseases, they are still a long way from being really brought under control. A well organized monitoring system would enable the epidemiological characteristics of the infectious diseases to be analyzed and the success or otherwise of preventive interventions to be precisely evaluated. For this reason, the World Health Organization and the European Union have discussed the formation of a collaborative network for the monitoring and control of re-emerging diseases and has initiated special programmes.

    Diabetic kidney disease – which is defined by elevated urine albumin excretion or reduced glomerular filtration rate (GFR) or both – is a serious complication that occurs in 20% to 40% of all diabetics. In this review we try to highlight the prevalence of diabetic nephropathy which is not uncommon complication of diabetes all over the world. The prevalence of diabetes worldwide has extended epidemic magnitudes and is expected to affect more than 350 million people by the year 2035. There is marked racial/ethnic besides international difference in the epidemiology of diabetic kidney disease which could be explained by the differences in economic viability and governmental infrastructures. Approximately one-third of diabetic patients showed microalbuminuria after 15 years of disease duration and less than half develop real nephropathy. Diabetic kidney disease (DKD) is more frequent in African-Americans, Asian-Americans, and Native Americans. Progressive kidney disease is more frequent in Caucasians patients with type 1 than type 2 diabetes mellitus (DM), although its overall prevalence in the diabetic population is higher in patients with type 2 DM while this type of DM is more prevalent. Hyperglycemia is well known risk factor for in addition to other risk factors like male sex, obesity, hypertension, chronic inflammation, resistance to insulin, hypovitaminosis D, and dyslipidemia and some genetic loci and polymorphisms in specific genes. Management of its modifiable risk factors might help in reducing its incidence in the nearby future. PMID:28197499

    The Automated Space System Experimental Testbed (ASSET) system is a simple yet comprehensive real-world operations network being developed. Phase 3 of the ASSET Project was January-December 1997 and 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) Principle Investigators 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 management, modeling and fault management capabilities that integrate the space and ground segments of the space system hardware. (5) Implement a beacon monitoring test. (6) Implement an experimental blackboard controller for space system management. (7) Further define typical ground station developments required for Internet-based remote control and for full system automation of the PI-to-spacecraft link. Each of those goals are examined. Significant sections of this report were also published as a conference paper. Several publications produced in support of this grant are included as attachments. Titles include: 1) Experimental Initiatives in Space System Operations; 2) The ASSET Client Interface: Balancing High Level Specification with Low Level Control; 3) Specifying Spacecraft Operations At The Product/Service Level; 4) The Design of a Highly Configurable, Reusable Operating System for Testbed Satellites; 5) Automated Health Operations For The Sapphire Spacecraft; 6) Engineering Data Summaries for Space Missions; and 7) Experiments In Automated Health

    In the next few years, several modest-sized telescopes around the world will be upgraded with autonomous laser adaptive optics systems based on the Robo-AO prototype deployed at the Palomar Observatory 1.5-m telescope. The prototype commenced scientific operations in June 2012 and more than 19,000 observations have since been performed at the ~0.12" visible-light diffraction limit. We are planning to move the prototype system to the 2.1-m telescope at Kitt Peak for a 3-year deployment which will serve a consortium of users including Caltech, the University of Hawai`i, IUCAA, NCU and institutions in China. Additionally, 2 months per year will be made available to the US astronomical community.New Robo-AO systems are in various stages of development: a clone by IUCAA for the 2-m IGO telescope in India; a natural guide star variant, KAPAO, by Pomona College at the 1-m Table Mountain telescope in California; and second generation Robo-AO systems are planned for the 3-m IRTF and 2.2-m University of Hawai'i telescopes on Maunakea, Hawai`i. The latter will exploit Maunakea's excellent observing conditions to provide higher Strehl ratios, sharper imaging, ~0.07", and correction to lambda = 400 nm. An additional infrared integral-field spectrograph will be fed by the UH 2.2-m Robo-AO system to quickly classify transients, such as supernovae and asteroids, discovered by the ATLAS system in Hawai`i.

    Despite attempts to generate interest in science and technology careers, US students continue to show reduced interest in science, technology, engineering and mathematics (STEM) majors at the collegiate level. If girls are not engaged in STEM learning by the middle school level, studies show that they are even less likely to choose a science- or engineering-related major. This article presents results from a workshop for 7th and 8th grade girls designed to promote knowledge building in the area of sustainability and alternative energy use in transportation and to stimulate greater interest in STEM subjects. The workshop based on research conducted at University X focused on basic concepts of electric vehicles and electric vehicles' batteries. Tests were conducted to evaluate the students' knowledge and perceptions of electric vehicles and to determine the impact of the workshop. Early exposure to meaningful engineering experiences for these young girls may boost interest and the eventual pursuit of engineering and technology education paths.

    The early life history of anadromous salmonid fishes, be they Atlantic (Salmo salar) or Pacific salmon (Oncorhynchus spp.), trout of those genera, or charrs (Salvelinus spp.), appears much more complex than previously thought. The seaward movement or migration is extremely polymorphic among and within species. To help provide understanding of the processes involved, and implications for conservation, management and husbandry, the 8th International Workshop on Smoltification was held on September 20–24, 2009, with participants from 9 different countries. Because the native distribution of these fishes is in northern latitudes, more or less circumglobally, similar workshops have been held roughly every four years in various countries, starting in LaJolla, California; and subsequently in Stirling, Scotland; Trondheim, Norway; St. Andrews, Canada; Muonio, Finland; Westport, Ireland; and Tono, Japan. Papers emanating from these previous workshops can be found in earlier Special Issues of Aquaculture while those from the 2009 workshop are presented here.

Over 150 delegates participated in this symposium including scientists, clinicians, health officials, policymakers and vaccine manufacturers from across Africa. Key topics discussed included rotavirus surveillance, rotavirus vaccine introduction, post rotavirus vaccine impact analysis and intussusception data and surveillance in Africa. The symposium provided early rotavirus vaccine adopter countries in Africa (South Africa, Ghana and Botswana) an opportunity to share up-to-date information on vaccine introduction, and allowed colleagues to share experiences in establishing routine rotavirus surveillance (Tanzania, Niger and Rwanda). Overall, the symposium highlighted the high burden of rotavirus in Africa, and the need to continue to strengthen efforts in preventing rotavirus diarrhoea in Africa.

  17. Predictors of cultural capital on science academic achievement at the 8th grade level

    NASA Astrophysics Data System (ADS)

    Misner, Johnathan Scott

    The purpose of the study was to determine if students' cultural capital is a significant predictor of 8th grade science achievement test scores in urban locales. Cultural capital refers to the knowledge used and gained by the dominant class, which allows social and economic mobility. Cultural capital variables include magazines at home and parental education level. Other variables analyzed include socioeconomic status (SES), gender, and English language learners (ELL). This non-experimental study analyzed the results of the 2011 Eighth Grade Science National Assessment of Educational Progress (NAEP). The researcher analyzed the data using a multivariate stepwise regression analysis. The researcher concluded that the addition of cultural capital factors significantly increased the predictive power of the model where magazines in home, gender, student classified as ELL, parental education level, and SES were the independent variables and science achievement was the dependent variable. For alpha=0.05, the overall test for the model produced a R2 value of 0.232; therefore the model predicted 23.2% of variance in science achievement results. Other major findings include: higher measures of home resources predicted higher 2011 NAEP eighth grade science achievement; males were predicted to have higher 2011 NAEP 8 th grade science achievement; classified ELL students were predicted to score lower on the NAEP eight grade science achievement; higher parent education predicted higher NAEP eighth grade science achievement; lower measures of SES predicted lower 2011 NAEP eighth grade science achievement. This study contributed to the research in this field by identifying cultural capital factors that have been found to have statistical significance on predicting eighth grade science achievement results, which can lead to strategies to help improve science academic achievement among underserved populations.

    Stamm, Rosemary A.; Houghton, Lisa A.

    2013-01-01

    Folate is a B-vitamin with particular importance during reproduction due to its role in the synthesis and maintenance of DNA. Folate is well known for its role in preventing neural tube defects (NTDs) during the periconceptional period. There is also an increased need for folate throughout pregnancy to support optimal growth and development of the fetus and blood volume expansion and tissue growth of the mother. During lactation, women are at risk of folate deficiency due to increased demands to accommodate milk folate levels. Nutrient Intake Values (NIVs) for folate have been calculated to take into account additional needs during pregnancy and lactation. However, these values vary widely between countries. For example, the folate requirement that is set to meet the needs of almost all healthy women during pregnancy varies from 300 µg/day in the United Kingdom to 750 µg/day in Mexico. Currently, there is no accepted standardized terminology or framework for establishing NIVs. This article reviews country-specific NIVs for folate during pregnancy and lactation and the basis for setting these reference values. PMID:24084052

    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.

    The Internet is rapidly evolving from a resource used primarily by the research community to a true global information network offering a wide range of databases and services. This evolution presents many opportunities for improved access to biomedical information, but Internet-based resources have often been difficult for the non-expert to develop and use. The World Wide Web (WWW) supports an inexpensive, easy-to-use, cross-platform, graphic interface to the Internet that may radically alter the way we retrieve and disseminate medical data. This paper summarizes the Internet and hypertext origins of the WWW, reviews WWW-specific technologies, and describes current and future applications of this technology in medicine and medical informatics. The paper also includes an appendix of useful biomedical WWW servers. PMID:8750386

    Background One relatively new and increasingly popular approach of increasing access to treatment is Web-based intervention programs. The advantage of Web-based approaches is the accessibility, affordability, and anonymity of potentially evidence-based treatment. Despite much research evidence on the effectiveness of Web-based interventions for anxiety found in the literature, little is known about what is publically available for potential consumers on the Web. Objective Our aim was to explore what a consumer searching the Web for Web-based intervention options for anxiety-related issues might find. The objectives were to identify currently publically available Web-based intervention programs for anxiety and to synthesize and review these in terms of (1) website characteristics such as credibility and accessibility; (2) intervention program characteristics such as intervention focus, design, and presentation modes; (3) therapeutic elements employed; and (4) published evidence of efficacy. Methods Web keyword searches were carried out on three major search engines (Google, Bing, and Yahoo—UK platforms). For each search, the first 25 hyperlinks were screened for eligible programs. Included were programs that were designed for anxiety symptoms, currently publically accessible on the Web, had an online component, a structured treatment plan, and were available in English. Data were extracted for website characteristics, program characteristics, therapeutic characteristics, as well as empirical evidence. Programs were also evaluated using a 16-point rating tool. Results The search resulted in 34 programs that were eligible for review. A wide variety of programs for anxiety, including specific anxiety disorders, and anxiety in combination with stress, depression, or anger were identified and based predominantly on cognitive behavioral therapy techniques. The majority of websites were rated as credible, secure, and free of advertisement. The majority required users to

  4. A large-scale study of the world wide web: network correlation functions with scale-invariant boundaries

    We performed a large-scale crawl of the world wide web, covering 6.9 million domains and 57 million subdomains, including all high-traffic sites of the internet. We present a study of the correlations found between quantities measuring the structural relevance of each node in the network (the in- and out-degree, the local clustering coefficient, the first-neighbor in-degree and the Alexa rank). We find that some of these properties show strong correlation effects and that the dependencies occurring out of these correlations follow power laws not only for the averages, but also for the boundaries of the respective density distributions. In addition, these scale-free limits do not follow the same exponents as the corresponding averages. In our study we retain the directionality of the hyperlinks and develop a statistical estimate for the clustering coefficient of directed graphs. We include in our study the correlations between the in-degree and the Alexa traffic rank, a popular index for the traffic volume, finding non-trivial power-law correlations. We find that sites with more/less than about 103 links from different domains have remarkably different statistical properties, for all correlation functions studied, indicating towards an underlying hierarchical structure of the world wide web.

    The development of the World Wide Web has led to an explosion of educational and clinical resources available via the Internet with minimal effort or special training. However, most of these Web pages contain only static information; few offer dynamic information shaped around clinical or laboratory test findings. In this report we show how this goal can be achieved with the design and construction of Medical Algorithm Web Pages (MAWP). Specifically, using Internet technologies known as forms and CGI scripts we demonstrate how one can implement medical algorithms remotely over the Internet's World Wide Web. To use a MAWP, one enters the URL for the site and then enters information according to the instructions presented there, usually by entering numbers and other information into fields displayed on screen. When all the data is entered, the user clicks on the SUBMIT icon, resulting in a new Web page being constructed "on-the-fly" containing diagnostic calculations and other information pertinent to the patient's clinical management. Four sample applications are presented in detail to illustrate the concept of a Medical Algorithm Web page: Computation of the alveolar-arterial oxygen tension difference using the alveolar gas equation; Computation of renal creatinine clearance; drug infusion calculation (micrograms/kilogram/minute); Computation of the renal failure index.

    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). PMID:21249219

    This paper presents an 8th order active-RC elliptic low-pass filter (LPF) for a direct conversion China Mobile Multimedia Broadcasting (CMMB) tuner with a 1 or 4 MHz -3 dB cutoff frequency (f-3dB). By using a novel gain-bandwidth-product (GBW) extension technique in designing the operational amplifiers (op-amps), the proposed filter achieves 71 dB stop-band rejection at 1.7 f-3dB to meet the stringent CMMB adjacent channel rejection (ACR) specifications while dissipates only 2.8 mA/channel from a 3 V supply, its bias current can be further lowered to 2 mA/channel with only 0.5 dB peaking measured at the filter's pass-band edge. Elaborated common-mode (CM) control circuits are applied to the filter op-amp to increase its common-mode rejection ratio (CMRR) and effectively reject the large signal common-mode interference. Measurement results show that the filter has 128 dBμVrms in-band IIP3 and more than 80 dB passband CMRR. Fabricated in a 0.35-μm SiGe BiCMOS process, the proposed filter occupies a 1.19 mm2 die area.

    From 8 th to 10 th of January 2009, significant snowfalls were reported in many areas of the Iberian Peninsula and the Balearic Islands. This relevant event was very important from the meteorological and social impact point of views. The snow affected many zones, especially the regions of Madrid, Castilla & León and Castilla-La Mancha (Spanish central plateau) with the persistence and thickness of solid precipitation. Up to twenty-five centimetres of snow were reported in some places. On 9th of January the snowfalls caused great social and media impact due to the fact that they took place in the early hours in the Madrid metropolitan areas, affecting both air traffic and land transport. The "Madrid-Barajas" airport was closed and the city was collapsed during several hours. A study of this situation appears in the poster. The snowstorm was characterized by the previous irruption of an European continental polar air mass, that subsequently interacted with a wet and warm air mass of Mediterranean origin, all preceded by low level easterly flows. This type of snowfall is called "warm advection". These winter situations are very efficient from precipitation point of view, generating significant snowfalls and affecting a lot of areas.

    In the handful of years since the World Wide Web (WWW or Web) came into being, Web sites have developed at an astonishing rate. With the influx of Web pages comes a disparity of site types, including personal homepages, commercial sales sites, and educational data. The variety of sites and the deluge of information contained on the Web exemplify the individual nature of the WWW. Whereas some people argue that it is this eclecticism which gives the Web its charm, we propose that sites which are repositories of technical data would benefit from standardization. This paper proffers a methodology for publishing ecological research on the Web. The template we describe uses capabilities of HTML (the HyperText Markup Language) to enhance the value of the traditional scientific paper.

  11. Local time variation in land/ocean lightning flash density as measured by the World Wide Lightning Location Network

    We study local time variation in high peak current lightning over land versus over ocean by using lightning locations from the World Wide Lightning Location Network (WWLLN). Optical lightning data from the photodiode detector on the Fast On-Orbit Recording of Transient Events (FORTE) satellite are used to determine the relative detection efficiency of the WWLLN for lightning events by region, as well as over land versus over ocean. We find that the peak lightning flash density varies for the different continents by up to 5 hours in local time. Because the WWLLN measures lightning strokes with large peak currents, the variation in local time of WWLLN-detected strokes suggests a similar variation in local time of transient luminous events (e.g., elves) and their effects on the lower ionosphere.

    This study has attempted to demonstrate the feasibility of obtaining information specific to foot and ankle orthopaedics from the World Wide Web (WWW). Six search engines (Lycos, AltaVista, Infoseek, Excite, Webcrawler, and HotBot) were used in scanning the Web for the following key words: "cavus foot," "diabetic foot," "hallux valgus,"and "pes equinovarus." Matches were classified by language, provider, type, and relevance to medical professionals or to patients. Sixty percent (407 sites) of the visited websites contained information intended for use by physicians and other medical professionals; 30% (206 sites) were related to patient information; 10% of the sites were not easily classifiable. Forty-one percent (169 sites) of the websites were commercially oriented homepages that included advertisements.

    The world wide web is an exciting service that allows one to publish electronic documents made of text and images on the internet. Client software called a web browser can access these documents, and display and print them. The most popular browsers are currently Microsoft Internet Explorer (Microsoft, Redmond, WA) and Netscape Communicator (Netscape Communications, Mountain View, CA). These browsers can display text in hypertext markup language (HTML) format and images in Joint Photographic Expert Group (JPEG) and Graphic Interchange Format (GIF). Currently, neither browser can display radiologic images in native Digital Imaging and Communications in Medicine (DICOM) format. With the aim to publish radiologic images on the internet, we wrote a dedicated Java applet. Our software can display radiologic and histologic images in DICOM, JPEG, and GIF formats, and provides a a number of functions like windowing and magnification lens. The applet is compatible with some web browsers, even the older versions. The software is free and available from the author.

    A computerized database was generated with the epidemiological data of more than 600 CSF virus strains and isolates kept in the EU Reference Laboratory for Classical Swine Fever in Hanover. In addition, as sequence data from defined regions of the genome are increasingly being used for genetic typing of new isolates and are thus being published, it was decided to integrate them into the database. In order to make the epidemiological and the sequence data available to other laboratories through the World Wide Web, a searchable web interface was programmed, which can be accessed using an Internet browser like Netscape or Internet Explorer. The possibility to exchange data via the web has the potential to increase our knowledge concerning genetic and epidemiological links between outbreaks worldwide.

    A custom-written Common Gateway Interface (CGI) program for remote control of an NMR spectrometer using a World Wide Web browser has been described. The program, running on a UNIX workstation, uses multiple processes to handle concurrent tasks of interacting with the user and with the spectrometer. The program's parent process communicates with the browser and sends out commands to the spectrometer; the child process is mainly responsible for data acquisition. Communication between the processes is via the shared memory mechanism. The WWW pages that have been developed for the system make use of the frames feature of web browsers. The CGI program provides an intuitive user interface to the NMR spectrometer, making, in effect, a complex system an easy-to-use Web appliance.

    Since human infections by Salmonella enterica serovar Enteritidis (Salmonella Enteritidis) have been increasing world-wide over the past years and epidemiological studies have implicated the consumption of meat, poultry, eggs and egg products, elucidation of the predominant subtypes for this Salmonella spp. is important. In this study, 107 poultry and food isolates of Salmonella Enteritidis obtained from Germany were analyzed by pulsed field gel electrophoresis (PFGE), and the subtypes were compared with those of the 124 human isolates obtained in Taiwan. Results showed that for these 107 poultry and food isolates, when XbaI, SpeI and NotI were used for chromosomal DNA digestion followed by PFGE analysis, a total of 19, 20 and 19 PFGE patterns, respectively, were identified. Of them, 51 (47.7%), 52 (48.6%) and 42 (39.3%) strains belong to a single pattern of X3, S3 and N3, respectively, and 34 strains belong to a pattern combination of X3S3N3, which was the major subtype. When PFGE patterns of these 107 German isolates were compared with those of the 124 human isolates obtained in Taiwan, pattern combination of X3S3N3 was found as the most common pattern shared by isolates from both areas. PT4 is a major phage type for German and Taiwan isolates. Although most of the X3S3N3 strains are of this phage type, some strains of other PFGE patterns are also of this phage type. Since strains used in this study were unrelated, i.e., they were isolated from different origins in areas geographically far apart from each other, the PFGE study suggests a major world-wide clone of S. enterica serovar Enteritidis.

    Foamy viruses naturally infect a wide range of mammals, including Old World (OWP) and New World primates (NWP), which are collectively called simian foamy viruses (SFV). While NWP species in Central and South America are highly diverse, only SFV from captive marmoset, spider monkey, and squirrel monkey have been genetically characterized and the molecular epidemiology of SFV infection in NWPs remains unknown. We tested a large collection of genomic DNA (n  = 332) comprising 14 genera of NWP species for the presence of SFV polymerase (pol) sequences using generic PCR primers. Further molecular characterization of positive samples was carried out by LTR-gag and larger pol sequence analysis. We identified novel SFVs infecting nine NWP genera. Prevalence rates varied between 14–30% in different species for which at least 10 specimens were tested. High SFV genetic diversity among NWP up to 50% in LTR-gag and 40% in pol was revealed by intragenus and intrafamilial comparisons. Two different SFV strains infecting two captive yellow-breasted capuchins did not group in species-specific lineages but rather clustered with SFVs from marmoset and spider monkeys, indicating independent cross-species transmission events. We describe the first SFV epidemiology study of NWP, and the first evidence of SFV infection in wild NWPs. We also document a wide distribution of distinct SFVs in 14 NWP genera, including two novel co-speciating SFVs in capuchins and howler monkeys, suggestive of an ancient evolutionary history in NWPs for at least 28 million years. A high SFV genetic diversity was seen among NWP, yet these viruses seem able to jump between NWP species and even genera. Our results raise concerns for the risk of zoonotic transmission of NWP SFV to humans as these primates are regularly hunted for food or kept as pets in forest regions of South America.

    Background. AIDA is a widely available downloadable educational simulator of glucose-insulin interaction in diabetes. Methods. A web-based version of AIDA was developed that utilises a server-based architecture with HTML FORM commands to submit numerical data from a web-browser client to a remote web server. AIDA online, located on a remote server, passes the received data through Perl scripts which interactively produce 24 hr insulin and glucose simulations. Results. AIDA online allows users to modify the insulin regimen and diet of 40 different prestored "virtual diabetic patients" on the internet or create new "patients" with user-generated regimens. Multiple simulations can be run, with graphical results viewed via a standard web-browser window. To date, over 637,500 diabetes simulations have been run at AIDA online, from all over the world. Conclusions. AIDA online's functionality is similar to the downloadable AIDA program, but the mode of implementation and usage is different. An advantage to utilising a server-based application is the flexibility that can be offered. New modules can be added quickly to the online simulator. This has facilitated the development of refinements to AIDA online, which have instantaneously become available around the world, with no further local downloads or installations being required.

    Between 1978 and 1983, 1127 patients with de-novo acute myeloid leukaemia (AML) were entered into the Medical Research Council (MRC)'s 8th AML trial. All received the same induction therapy consisting of daunorubicin, cytarabine, and 6-thioguanine--DAT (1 + 5). The 67% who entered complete remission were randomised to consolidation with two or six further courses of DAT. Adults under the age of 55 were randomised for central nervous system (CNS) prophylaxis with intrathecal cytarabine and methotrexate. Finally, those still in remission after 1 year of cytarabine and 6-thioguanine (AT) maintenance were randomised to receive either late intensification with cyclophosphamide, vincristine, cytarabine, and prednisolone (COAP) or continued AT. The median survival for the whole group was 12 months; the median duration of first remission was 15 months, with relapse-free survival at 5 years estimated at 18%. The factors most strongly associated with poor survival were performance status and age at presentation, but even among those over 60 years of age, half went into remission. Six courses of DAT consolidation gave a small advantage over two courses in reducing the number of late relapses but no significant survival advantage. Late intensification showed a marginally significant advantage over continued AT maintenance. The incidence of CNS relapse was low and unaffected by prophylaxis. The second remission rate varied from 10% when the first remission was shorter than 6 months to 61% when it had continued for more than 2 years. 40 patients received histocompatible allogeneic bone-marrow transplants in first remission. There was a high procedure-related death rate, particularly among patients over 30 years of age. Thus, initially at least, the transplanted group had shorter survival than a comparable group of chemotherapy-treated patients. Treatment specifications remained unchanged throughout the trial but those enrolled in the later half of the trial had a better (p = 0

    Background: Newer dentin bonding agents were developed to improve the quality of composite restoration and to reduce time consumption in its application. The aim of the present study was to evaluate tensile bond strength of 6th, 7th and 8th generation bonding agents by in vitro method. Materials and Methods: Selected 60 permanent teeth were assigned into 20 in each group (Group I: 6th generation bonding agent-Adper SE plus 3M ESPE, Group II: 7th generation bonding agent-G-Bond GC Corp Japan and Group III: 8th generation dentin adhesives-FuturaBond, DC, Voco, Germany). With high-speed diamond disc, coronal dentin was exposed, and selected dentin bonding agents were applied, followed by composite restoration. All samples were saved in saline for 24 h and tensile bond strength testing was done using a universal testing machine. The obtained data were tabulated and statistically analyzed using ANOVA test. Results: The tensile bond strength readings for 6th generation bonding agent was 32.2465, for 7th generation was 31.6734, and for 8th-generation dentine bonding agent was 34.74431. The highest tensile bond strength was seen in 8th generation bonding agent compared to 6th and 7th generation bonding agents. Conclusion: From the present study it can be conclude that 8th generation dentine adhesive (Futura DC, Voco, Germany) resulted in highest tensile bond strength compared to 6th (Adper SE plus, 3M ESPE) and 7th generation (G-Bond) dentin bonding agents.

  14. Toward Robust Climate Baselining: Objective Assessment of Climate Change Using Widely Distributed Miniaturized Sensors for Accurate World-Wide Geophysical Measurements

    A gap-free, world-wide, ocean-, atmosphere-, and land surface-spanning geophysical data-set of three decades time-duration containing the full set of geophysical parameters characterizing global weather is the scientific perquisite for defining the climate; the generally-accepted definition in the meteorological community is that climate is the 30-year running-average of weather. Until such a tridecadal climate base line exists, climate change discussions inevitably will have a semi-speculative, vs. a purely scientific, character, as the baseline against which changes are referenced will be at least somewhat uncertain. The contemporary technology base provides ways-and-means for commencing the development of such a meteorological measurement-intensive climate baseline, moreover with a program budget far less than the {approx}$2.5 B/year which the US. currently spends on ''global change'' studies. In particular, the recent advent of satellite-based global telephony enables real-time control of, and data-return from, instrument packages of very modest scale, and Silicon Revolution-based sensor, data-processing and -storage advances permit 'intelligent' data-gathering payloads to be created with 10 gram-scale mass budgets. A geophysical measurement system implemented in such modern technology is a populous constellation 03 long-lived, highly-miniaturized robotic weather stations deployed throughout the weather-generating portions of the Earths atmosphere, throughout its oceans and across its land surfaces. Leveraging the technological advances of the OS, the filly-developed atmospheric weather station of this system has a projected weight of the order of 1 ounce, and contains a satellite telephone, a GPS receiver, a full set of atmospheric sensing instruments and a control computer - and has an operational life of the order of 1 year and a mass-production cost of the order of $20. Such stations are effectively ''intra-atmospheric satellites'' but likely have serial

    The 8th International Conference on Strangeness in Quark Matter (SQM2004) was held at at the Breakwater Lodge, which is part of the Graduate School of Business of the University of Cape Town. The architecture of the Breakwater Lodge is a stark reminder of the fact that its original purpose was to serve as a municipal jail. It appears that the spectacular background of Table Mountain and the V&A Waterfront and an excellent set of speakers were sufficient to keep the lecture rooms full to capacity, despite the numerous temptations of Cape Town. This is the first time a major heavy ion conference has been held in South Africa, and the timing is fortuitous, with a long-delayed MoU between South Africa and CERN at last being signed and finalized. At last, funding is being made available for South African scientists to play a meaningful role and make contributions to the international effort in heavy ion physics. Despite the substantial distance from the major cities in the northern hemisphere, the conference was very well attended and the number of participants was about 50% larger than originally anticipated. Participants came from China, India, Japan, the United States, Brazil and many European countries. We would like to thank all of the SQM2004 participants for their efforts and, in particlular, all of the plenary and parallel speakers for their hard work in making this conference such a success. Of course, even more thanks go to all the chairpersons of the various sessions who struggled to keep the conference program on the (admittedly tight) schedule. For future conferences, we recommend keeping a bell handy! Photograph Participants gather on the UCT campus with Table Mountain in the backgound. We would like to thank Professor Tony Fairall for a most entertaining after-dinner talk about all that is unusual and fascinating about the southern hemisphere. It could not be emphasized enough that the daily working of the meeting would have ground to a halt without the

    During winter season snow precipitation is quite frequent in the Pyrenees (north-east of the Iberian Peninsula). On average the total amount of fresh snow at 2200 metres is of 250 cm. However, important snow episodes at low latitudes are unlikely. From 1947 to 2009, 16 significant snow episodes took place in the Barcelona and 18 in Girona areas. On 8th March 2010, a severe wet snow event had a high social impact on these regions. One of the most remarkable features of this episode was the type of precipitation (wet snow) and the large amount of precipitation combined with strong wind gust that caused the collapse of electricity pylons and tree forests. The damage was very important in the north-eastern part and the regional government approved funds of 21.4 million € to reduce the impact caused by this event. Although diagnosis of other low altitude snowfall events in Catalonia has been done previously, the analysis of this event can contribute to characterise a little bit better these snow episodes. In this study, we will present the synoptic framework characterised by the presence of a deep low in the north-east of Catalonia and moving through Ebro valley to the Catalan coast. To do this we will use ECMWF reanalyses and Meteosat images. The main features to predict this snow event and the critical point were the total amount of precipitation and snow level forecasted by mesoscale models (MM5, WRF). The model outputs for precipitation, temperature and wind will be compared with automatic weather, radar and radiosounding data. The snow level and the type of precipitation are compared with the information received from spotters. The main storm was characterised by moderate vertical development with tops of 8 km (4 km were the average height during the initial and final phase of the event). Also, lightning activity was observed, 310 intra-cloud and 128 cloud-to-ground. The type of precipitation at a specific location in the eastern zone temporally changed because

    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.

    The applications of DNA profiling aim to identify perpetrators, missing family members and disaster victims in forensic investigations. Single nucleotide polymorphisms (SNPs) based forensic applications are emerging rapidly with a potential to replace short tandem repeats (STRs) based panels which are now being used widely, and there is a need for a well-designed SNP panel to meet such challenge for this transition. Here we present a panel of 175 SNP markers (referred to as Fudan ID Panel or FID), selected from ∼3.6 million SNPs, for the application of personal identification. We optimized and validated FID panel using 729 Chinese individuals using a next generation sequencing (NGS) technology. We showed that the SNPs in the panel possess very high heterozygosity as well as low within- and among-continent differentiations, enabling FID panel exhibit discrimination power in both regional and worldwide populations, with the average match probabilities ranging from 4.77×10(-71) to 1.06×10(-64) across 54 world populations. With the advent of biomedical research, the SNPs connecting physical anthropological, physiological, behavioral and phenotypic traits will be eventually added to the forensic panels that will revolutionize criminal investigation.

  20. PREFACE: 8th International Conference on Fine Particle Magnetism (ICFPM2013)

    2014-06-01

    The 8th International Conference on Fine Particle Magnetism (ICFPM) was held in Perpignan from 24 to 27 June 2013, and was the continuation of the previous meetings held in Bangor (1996), Rome (1991), Barcelona (1999), Pittsburg (2002), London (2004), Rome (2007) and Uppsala (2010). The next meeting will be organized by Profs. Robert D. Shull, George Hadjipanayis and Cindi Dennis, in 2016 at NIST, Gaithersburg (USA). ICFPM is a small-sized conference focused on the magnetism of nanoparticles. It provides an international forum for discussing the state-of-the-art understanding of physics of these systems, of their properties and the underlying phenomena, as approached from a variety of directions: theory and modelling, experiments on well characterized or model systems (both fabricated and synthetised), as well as experiments on technologically-relevant non-ideal systems. This meeting brought together about 120 participants working on experimental, theoretical and applied topics of the multidisciplinary research areas covered by magnetic nanoparticles, with focused interest on either single-particle or collective phenomena. The technical program of the conference was based on keynote conferences, invited talks, oral contributions and poster sessions, covering the following aspects: . Fabrication, synthesis, characterization . Single particle, surface and finite-size effects on magnetic properties . Magnetization dynamics, micro-wave assisted switching, dynamical coupling . Assemblies, collective effects, self-assembling and nanostructuring . Applications : hyperthermia, drug delivery, magneto-caloric, magneto-resistance, magneto-plasmonics, magnetic particle imaging This ICFPM edition was organized by the group Nanoscale Spin Systems of the laboratory PROMES of the CNRS (UPR8521), and Université de Perpignan Via Domitia. The meeting took place at the Congress Center of the city of Perpignan providing high-quality facilities for the technical program as well for the

    Chronic kidney disease (CKD) is a pandemic and the need to inform those at risk has never been more important. The World Wide Web (WWW) is no w considered a key source of health information, but the quality and utility of this information has been challenged. In this article, we assess structural, content, and linguistic barriers to accessed CKD information and discuss the implications of limited Internet access to communicating health. Technical (number of hyperlinks), content (number of six core CKD and risk factor information domains included), and linguistic (readability and variation in readability) barriers were assessed for websites offered by 12 kidney disease associations. The Flesch Reading Ease Index method was used to estimate readability scores, and variation in the readability of information was assessed. Eleven websites met inclusion criteria. Six of 11 websites provided information in all 6 domains of CKD information. A mean of 4 hyperlinks (range 3-5) was clicked before CKD information was available and a mean of 6 hyperlinks (range 4-12) was clicked to access all available CKD information. Mean readability scores for all six domains of CKD information exceeded national average literacy skills and far exceeded the 5th grade level readability desired for informing vulnerable populations. Information about CKD and diabetes consistently had higher readability scores. The WWW currently has little utility for informing populations at greatest risk for CKD. Barriers to accessing CKD information on the WWW are socioeconomic, technical, and linguistic. Having lower socioeconomic status, less access to computers and the WWW, multiple website hyperlinks, incomplete information, difficult readability, and significant variation in readability of CKD information on the WWW are social, structural, and content barriers to communicating CKD information. This may contribute to the growing epidemics of diminished public understanding about CKD, and disparities in

    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

    Objective To examine the relationship between perceived family support and other selected correlates of physical activity (PA) with changes in PA over time. Methods A total of 421 girls in South Carolina completed questionnaires at 8th, 9th and 12th grades (1998–2003). Family support for PA, PA self-efficacy, perceived behavioral control, attitudes, availability of equipment, and PA were measured. Results Growth curve analysis showed that family support, perceived behavioral control, and self-efficacy were independently related to age-related changes in PA as reflected by total METs. Girls who reported lower family support at the 8th grade measure had more rapid declines in PA, and a unit change in family support was related to approximately 1/3 of a standard deviation change in total METs. Conclusions Maintenance of support from family members may reduce the decline in PA independent of girl’s self-efficacy and perceived behavioral control. PMID:17157371

    Natural forests store vast amounts of carbon in the terrestrial biosphere, and play an important role in the global carbon cycle. Given the significance of natural forests, there is a lack of carbon accounting of primary forests that are undisturbed by human activities. One reason for this lack of interest stems from ecological orthodoxy that suggests that primary forests should be close to dynamic equilibrium, in that Net Ecosystem Production (NEP) approaches zero. However, recent results from the northern hemisphere and tropics, using eddy covariance flux towers, indicate that primary forests are a greater sink than first thought. The role of evergreen primary forests in Australian carbon balance studies remain uncertain and hence may function differently to their deciduous counterparts in the Northern Hemisphere. In order to address the lack of baseline carbon accounts, an undisturbed, 300 year old Mountain Ash (Eucalyptus regnans) ecosystem, located in the Central Highlands of Victoria (Australia) was selected as a permanent study site to investigate carbon and water budgets over diurnal, seasonal and annual cycles. Mountain Ash trees are the world's tallest angiosperms (flowering plants), and one of the largest carbon reservoirs in the biosphere, with an estimated 1900 tC ha-1. A 110 m tall micrometeorological tower that includes eddy covariance instrumentation was installed in August 2005. An independent biometric approach quantifying the annual net gain or loss of carbon was also made within close proximity to the flux tower. Analysis of NEP in 2006 suggests that the ecosystem acted as a carbon sink of 2.5 tC ha-1 yr-1. Woody and soil biomass increment for the same year was estimated to be 2.8 tC ha-1yr-1, in which nearly half of the biomass production was partitioned into the aboveground woody tissue. These results indicate that temperate primary forests act as carbon sinks, and are able to maintain their carbon sink status due to their uneven stand

  7. Evolution and connectivity in the world-wide migration system of the mallard: Inferences from mitochondrial DNA

    PubMed Central

    2011-01-01

    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 hypotheses and conclude that a

  13. The world-wide increase in tuberculosis: how demographic changes, HIV infection and increasing numbers in poverty are increasing tuberculosis.

    PubMed

    Davies, Peter D O

    2003-01-01

    After more than a century of decline, in the mid 1980s tuberculosis began to increase in some developed countries. Health care workers were then forced to look to the developing world, where they found tuberculosis to be out of control, in many countries. It is now appreciated that tuberculosis is not only increasing globally but is likely to do so beyond the next decade for three principal reasons. First, demographically as the expected population increase will be greatest in areas of the world where tuberculosis is most prevalent, particularly middle Africa and South Asia. Secondly, the increase of HIV, which renders the host uniquely susceptible to tuberculosis, is occurring in the same areas of the world and is already causing an increase in tuberculosis case rates of up to tenfold. Thirdly, as more and more people are forced to live in poverty, where poor nutrition and crowded conditions lead to the spread of tuberculosis, the disease risk will be compounded. Sound medical management, particularly the use of the five components of directly observed therapy, will relieve the situation. But until world conditions of poverty and HIV spread are addressed, it is unlikely that tuberculosis can be controlled.

    The results are summarized of a program to demonstrate the feasibility of Bubble Domain Memory Technology as a mass memory medium for spacecraft applications. The design, fabrication and test of a partially populated 10 to the 8th power Bit Data Recorder using 100 Kbit serial bubble memory chips is described. Design tradeoffs, design approach and performance are discussed. This effort resulted in a 10 to the 8th power bit recorder with a volume of 858.6 cu in and a weight of 47.2 pounds. The recorder is plug reconfigurable, having the capability of operating as one, two or four independent serial channel recorders or as a single sixteen bit byte parallel input recorder. Data rates up to 1.2 Mb/s in a serial mode and 2.4 Mb/s in a parallel mode may be supported. Fabrication and test of the recorder demonstrated the basic feasibility of Bubble Domain Memory technology for such applications. Test results indicate the need for improvement in memory element operating temperature range and detector performance.

    2014-01-01

    Background Poor quality medicines threaten the lives of millions of patients and are alarmingly common in many parts of the world. Nevertheless, the global extent of the problem remains unknown. Accurate estimates of the epidemiology of poor quality medicines are sparse and are influenced by sampling methodology and diverse chemical analysis techniques. In order to understand the existing data, the Antimalarial Quality Scientific Group at WWARN built a comprehensive, open-access, global database and linked Antimalarial Quality Surveyor, an online visualization tool. Analysis of the database is described here, the limitations of the studies and data reported, and their public health implications discussed. Methods The database collates customized summaries of 251 published anti-malarial quality reports in English, French and Spanish by time and location since 1946. It also includes information on assays to determine quality, sampling and medicine regulation. Results No publicly available reports for 60.6% (63) of the 104 malaria-endemic countries were found. Out of 9,348 anti-malarials sampled, 30.1% (2,813) failed chemical/packaging quality tests with 39.3% classified as falsified, 2.3% as substandard and 58.3% as poor quality without evidence available to categorize them as either substandard or falsified. Only 32.3% of the reports explicitly described their definitions of medicine quality and just 9.1% (855) of the samples collected in 4.6% (six) surveys were conducted using random sampling techniques. Packaging analysis was only described in 21.5% of publications and up to twenty wrong active ingredients were found in falsified anti-malarials. Conclusions There are severe neglected problems with anti-malarial quality but there are important caveats to accurately estimate the prevalence and distribution of poor quality anti-malarials. The lack of reports in many malaria-endemic areas, inadequate sampling techniques and inadequate chemical analytical methods and

    In an era when the number of Earth-observing satellites is rapidly growing and measurements from these sensors are used to answer increasingly urgent global issues, it is imperative that scientists and decision-makers can rely on the accuracy of Earth-observing data products. The characterization and calibration of these sensors are vital to achieve an integrated Global Earth Observation System of Systems (GEOSS) for coordinated and sustained observations of Earth. The U.S. Geological Survey (USGS), as a supporting member of the Committee on Earth Observation Satellites (CEOS) and GEOSS, is working with partners around the world to establish an online catalog of prime candidate test sites for the post-launch characterization and calibration of space-based optical imaging sensors. The online catalog provides easy public Web site access to this vital information for the global community. This paper describes the catalog, the test sites, and the methodologies to use the test sites. It also provides information regarding access to the online catalog and plans for further development of the catalog in cooperation with calibration specialists from agencies and organizations around the world. Through greater access to and understanding of these vital test sites and their use, the validity and utility of information gained from Earth remote sensing will continue to improve.

    The 8th African Rotavirus Symposium was held in Livingstone, Zambia from the 12-13 June 2014. Over 130 delegates from 35 countries - 28 from African nations - participated in this symposium, which included scientists, clinicians, immunisation managers, public health officials, policymakers and vaccine manufacturers. The theme for the symposium was Rotavirus Landscape in Africa-Towards Prevention and Control. At the time of the symposium, a total of 21 African countries had introduced the rotavirus vaccine into their national immunisation schedules. This meeting was particularly timely and relevant to review early data on vaccine adoption and impact from these countries. The concluding panel discussion proposed several recommendations for areas of focus moving forward in rotavirus advocacy and research.

    This cross-sectional school-based study explored the relationship between adolescent use of cigarettes and marijuana and the sensation seeking personality factors of (1) Disinhibition and (2) Thrill and Adventure Seeking. The study population included a representative sample of both male and female 8th and 11th graders in the state of Delaware. Analytic methods utilized included correlational analysis and multivariate logistic regression. In the multivariate logistic regression models, the Disinhibition personality factor accounted for cigarette and marijuana using behaviors with odds ratios ranging between 2 and 3. Thrill and Adventure Seeking was not a significant explanatory variable in any of the final multivariate models. Potential confounders (age, gender and race) were considered in all analyses. Of all the two-way interactions assessed, none was significant. The findings from this study utilizing a large general community sample indicate that sensation seeking needs are a potential risk factor for adolescent substance use.

    We analyzed 178 Streptococcus thermophilus strains isolated from diverse products, from around the world, over a 60-year period with a new multilocus sequence typing (MLST) scheme. This collection included isolates from two traditional cheese-making sites with different starter-use practices, in sampling campaigns carried out over a three years period. The nucleotide diversity of the S. thermophilus population was limited, but 116 sequence types (ST) were identified. Phylogenetic analysis of the concatenated sequences of the six housekeeping genes revealed the existence of groups confirmed by eBURST analysis. Deeper analyses performed on 25 strains by CRISPR and whole-genome analysis showed that phylogenies obtained by MLST and whole-genome analysis were in agreement but differed from that inferred by CRISPR analysis. Strains isolated from traditional products could cluster in specific groups indicating their origin, but also be mixed in groups containing industrial starter strains. In the traditional cheese-making sites, we found that S. thermophilus persisted on dairy equipment, but that occasionally added starter strains may become dominant. It underlined the impact of starter use that may reshape S. thermophilus populations including in traditional products. This new MLST scheme thus provides a framework for analyses of S. thermophilus populations and the management of its biodiversity.

    Species' geographical distributions are tracking latitudinal and elevational surface temperature gradients under global climate change. To evaluate the opportunities to track these gradients across space, we provide a first baseline assessment of the steepness of these gradients for the world's terrestrial birds. Within the breeding ranges of 9,014 bird species, we characterized the spatial gradients in temperature along latitude and elevation for all and a subset of bird species, respectively. We summarized these temperature gradients globally for threatened and non-threatened species and determined how their steepness varied based on species' geography (range size, shape, and orientation) and projected changes in temperature under climate change. Elevational temperature gradients were steepest for species in Africa, western North and South America, and central Asia and shallowest in Australasia, insular IndoMalaya, and the Neotropical lowlands. Latitudinal temperature gradients were steepest for extratropical species, especially in the Northern Hemisphere. Threatened species had shallower elevational gradients whereas latitudinal gradients differed little between threatened and non-threatened species. The strength of elevational gradients was positively correlated with projected changes in temperature. For latitudinal gradients, this relationship only held for extratropical species. The strength of latitudinal gradients was better predicted by species' geography, but primarily for extratropical species. Our findings suggest threatened species are associated with shallower elevational temperature gradients, whereas steep latitudinal gradients are most prevalent outside the tropics where fewer bird species occur year-round. Future modeling and mitigation efforts would benefit from the development of finer grain distributional data to ascertain how these gradients are structured within species' ranges, how and why these gradients vary among species, and the capacity

    A typical improved-pasture property in the high-rainfall zone of Australia contains 0.5-2.0 km of waterways per 100 ha. Nationwide, some 25-30 million ha of improved pasture contains about 100,000 km of streams, of which about 75% are currently un-buffered and contributing to soil and water degradation. Farmers and natural resource managers are considering ways to enhance environmental outcomes at farm and catchment scales using stream-side buffers of trees and other perennial vegetation. Benefits of buffers include improved water quality, biodiversity, carbon sequestration and aesthetics. Lack of sound information and funding for establishing and managing buffer zones is hindering wide-scale adoption of this practice. Stream-side areas of farms are generally highly productive (wet and nutrient-rich) and contain a high biodiversity, but they are also high-risk zones for soil and water values and stock safety. Development of options based on a balance between environmental and economic outcomes would potentially promote wider adoption. Australian codes of forest practice currently discourage or prevent harvesting of trees in streamside buffers. These codes were developed exclusively for large-scale native forests and industrial-scale plantations, and were applicable to farm forestry as now required. In countries including USA and Germany trees in stream-side buffers are harvested using Best Management Practices. Trees may grow at a faster rate in riparian zones and provide a commercial return, but the impacts of tree establishment and harvesting on water yield and quality must be evaluated. However, there have been few designed experiments investigating this problem. Australia has recently initiated studies to explore the use of high-value timber species and associated vegetation in riparian zones to improve water quality, particularly suspended sediment. Preliminary information from the Yan Yan Gurt Catchment in Victoria indicate that forested riparian strips can

    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.

  19. Ongoing problems concerning 7th TNM Staging System and Proposals for 8th TNM Staging System of Gastric Cancer

    2016-01-01

    Because of different prognosis of gastric cancer patients with the same T and N stages, the impossibility of N3 staging in patients with fewer than 15 removed lymph nodes, and the presence of stage migration phenomenon, the 6th edition TNM Staging System for gastric cancer was updated to the 7th edition TNM staging system in 2009. Despite some opposing views, the superiority of the 7th edition TNM staging system compared to the 6th has been demonstrated in many studies. However, there are doubts about the 7th edition that it will reduce the stage migration phenomenon. The most important problem about the 7th TNM staging system is regarding subgroups N3a and N3b. The separation of N3 stage as N3a and N3b does not contribute to the TNM staging system. In conclusion, separate usage of N3a and N3b subgroups in the TNM staging system should be considered in the creation phase of the 8th edition. PMID:28053675

    Fast food consumption is a dietary factor associated with higher prevalence of childhood obesity in the United States. The association between food prices and consumption of fast food among 5th and 8th graders was examined using individual-level random effects models utilizing consumption data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998-99 (ECLS-K), price data from American Chamber of Commerce Researchers Association (ACCRA), and contextual outlet density data from Dun and Bradstreet (D&B). The results found that contextual factors including the price of fast food, median household income, and fast food restaurant outlet densities were significantly associated with fast food consumption patterns among this age group. Overall, a 10% increase in the price of fast food was associated with 5.7% lower frequency of weekly fast food consumption. These results suggest that public health policy pricing instruments such as taxes may be effective in reducing consumption of energy-dense foods and possibly reducing the prevalence of overweight and obesity among US children and young adolescents.

    The practice and science of pharmacovigilance first emerged following the disaster caused by thalidomide in 1961, which led to the initiation of systemic international efforts to address drug safety issues spearheaded by the WHO. Systems were developed in member states of the WHO to analyze cases of adverse drug reactions (ADRs) and collate these data into a central database to aid national drug regulatory authorities in improving safety profiles of medicines. Pharmacovigilance is a key public health function for monitoring all medicinal products to assess their quality, efficacy and safety before and following authorization. These medicines are continually assessed to detect any aspect that could compromise their safety, and ensure that the necessary measures are taken. In July 2012, new legislation for pharmacovigilance in the E.U. came into effect as a result of the changes set out in the Directive 2010/84/EU and the European Commission (EC) implementing Regulation (EU) No 520/2012 to reduce the increasing number of ADRs. The latest developments in pharmacovigilance in Europe, including news on E.U. pharmacovigilance legislation, were discussed at the 8th European Generic Medicines Association (EGA) Pharmacovigilance Discussion Forum. The meeting facilitated constructive dialogue between regulators and industry on a range of topics including how to simplify pharmacovigilance activities and improve the processes of risk management plans, periodic safety update reports, signal detection, joint studies and inspections.

At that time Prof. Sjöqvist and his unit had already earned an international reputation, and in the following decades this success has been magnified many times. Although a description of the research performed by Prof. Sjöqvist during his long career is not the main objective of this article, it is clear that the research carried out in his unit has been instrumental in the development of his international reputation. Over an 18-year period from 1994 onwards, some 272 papers bearing the name of Folke Sjöqvist have been cited over 13,000 times, with an average of over 50 citations per paper. In terms of training clinical pharmacologists from around the world, at the last count 112 individuals from 37 different countries have received a substantial part of their training in his unit. As another measure of his world-wide success, 33 individuals from 18 different countries who received a substantial part of their training in his unit between 1968 and 1996 have gone on to become professors of clinical pharmacology. Prof. Sjöqvist has been requested to consult on various aspects of clinical pharmacology in 15 different countries, from Russia to Spain and from Egypt to Latvia. Here I describe the long-term involvement that Prof. Sjöqvist has had with IUPHAR (now the International Union of Basic and Clinical Pharmacology) and with institutions such as the World Health Organisation (WHO). In particular, I recount his role in the long-term saga involved in updating the original WHO manifesto on clinical pharmacology published in 1970 up to the eventual success of the new manifesto published by WHO in 2012. Finally, I briefly describe the international honours that have been bestowed on Prof. Sjöqvist, including various prizes, designated lectureships and honorary Doctorates (5). Taken together, these

    Studies conducted nationwide over the past several decades point consistently to the evidence that American school children lag behind several other countries in science scores. Problems arise from this dilemma, including the question of the ability of our youngsters to compete nationally and globally in the sciences as adults. Current research in this area of scores currently studies mostly mathematics. The few studies conducted concerning science mainly highlight students in other countries and neglects minorities and females regarding outcomes. By contrast, this study investigated the effects of teacher types (also defined as teaching styles or classroom orientation) on student outcomes on two measures; the standardized Standards of Learning 8th grade science test for the state of Virginia, and the Higher-Order Skills test (Berube, 2001), which was a researcher-constricted comprehension measurement. Minority and gender interactions were analyzed as well. Teacher type was designated by using the Constructivist Learning Environment Survey (Taylor & Fraser, 1991). Participants included students from five large urban middle schools and thirteen middle school science teachers. Scores from the two measures were used to determine differences in student outcomes as they pertained to teacher type, gender and ethnicity. Analysis indicated that students who were taught by teachers with more traditional and mixed teaching styles performed better on the Higher-Order Skills comprehension measurement, while teachers with constructivist teaching styles actually had the lowest scoring students. Also, the interaction of ethnicity and teacher type was significant, indicating that Higher-Order Skills scores were influenced by that interaction, with Caucasians scoring the highest when taught by teachers with mixed teaching styles. Such findings could profit school administrators considering the interaction of student achievement and teaching styles on high-stakes testing

    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.

  13. Is there a species spectrum within the world-wide leaf economics spectrum? Major variations in leaf functional traits in the Mediterranean sclerophyll Quercus ilex.

    PubMed

    Niinemets, Ulo

    2015-01-01

    The leaf economics spectrum is a general concept describing coordinated variation in foliage structural, chemical and physiological traits across resource gradients. Yet, within this concept,the role of within-species variation, including ecotypic and plastic variation components, has been largely neglected. This study hypothesized that there is a within-species economics spectrum within the general spectrum in the evergreen sclerophyll Quercus ilex which dominates low resource ecosystems over an exceptionally wide range. An extensive database of foliage traits covering the full species range was constructed, and improved filtering algorithms were developed. Standardized data filtering was deemed absolutely essential as additional variation sources can result in trait variation of 10–300%,blurring the broad relationships. Strong trait variation, c. two-fold for most traits to up to almost an order of magnitude, was uncovered.Although the Q. ilex spectrum is part of the general spectrum, within-species trait and climatic relationships in this species partly differed from the overall spectrum. Contrary to world-wide trends, Q. ilex does not necessarily have a low nitrogen content per mass and can increase photosynthetic capacity with increasing foliage robustness. This study argues that the within-species economics spectrum needs to be considered in regional- to biome-level analyses.

    OBJECTIVE: To assess the reliability of healthcare information on the world wide web and therefore how it may help lay people cope with common health problems. METHODS: Systematic search by means of two search engines, Yahoo and Excite, of parent oriented web pages relating to home management of feverish children. Reliability of information on the web sites was checked by comparison with published guidelines. MAIN OUTCOME MEASURES: Minimum temperature of child that should be considered as fever, optimal sites for measuring temperature, pharmacological and physical treatment of fever, conditions that may warrant a doctor's visit. RESULTS: 41 web pages were retrieved and considered. 28 web pages gave a temperature above which a child is feverish; 26 pages indicated the optimal site for taking temperature, most recommending rectal measurement; 31 of the 34 pages that mentioned drug treatment recommended paracetamol as an antipyretic; 38 pages recommended non-drug measures, most commonly tepid sponging, dressing lightly, and increasing fluid intake; and 36 pages gave some indication of when a doctor should be called. Only four web pages adhered closely to the main recommendations in the guidelines. The largest deviations were in sponging procedures and how to take a child's temperature, whereas there was a general agreement in the use of paracetamol. CONCLUSIONS: Only a few web sites provided complete and accurate information for this common and widely discussed condition. This suggests an urgent need to check public oriented healthcare information on the internet for accuracy, completeness, and consistency. PMID:9224132

    This issue of Superconductor Science and Technology (SuST) contains plenary and invited papers presented at the 8th European Conference on Applied Superconductivity (EUCAS '07) held in Brussels, Belgium between 16-20 September 2007. All the papers that were submitted to the Conference Proceedings and accepted by the referees are published in Journal of Physics: Conference Series (JPCS). The scientific aims of EUCAS '07 followed the tradition established at the preceding conferences in Göttingen (Germany), Edinburgh (United Kingdom), Eindhoven (The Netherlands), Sitges (Spain), Lyngby (Denmark), Sorrento (Italy) and Vienna (Austria). The focus was on the interplay between the most recent developments in superconductor research and the positioning of applications of superconductivity in the marketplace. Although initially founded as an exchange forum mainly for European scientists, it has gradually developed into a truly international meeting with significant attendance from the Far East and the United States. Under the guidance of ESAS (the European Society for Applied Superconductivity), this Brussels conference was jointly organized by the University of Ghent and the University of Liège and attracted 795 participants to the scientific programme, including 173 students. Participants from 46 countries included considerable attendance from the Far East (30%) and from the United States and Canada (7%). The latest developments from 30 companies were presented, and 13 plenary and 28 invited lectures highlighted the state-of-the-art in the area of materials (large- as well as small-scale applications were presented). A total of 347 papers from those submitted were selected for publication in JPCS and SuST. EUCAS '07 stimulated optimism and enthusiasm for this fascinating field of research and its technological potential, especially among the numerous young researchers attending this conference. In addition, it gave the leading scientific authorities a forum in which

    This article discusses the perioperative management of antithrombotic therapy and is part of the American College of Chest Physicians Evidence-Based Clinical Practice Guidelines (8th Edition). The primary objectives of this article are the following: (1) to address the perioperative management of patients who are receiving vitamin K antagonists (VKAs) or antiplatelet drugs, such as aspirin and clopidogrel, and require an elective surgical or other invasive procedures; and (2) to address the perioperative use of bridging anticoagulation, typically with low-molecular-weight heparin (LMWH) or unfractionated heparin (UFH). A secondary objective is to address the perioperative management of such patients who require urgent surgery. The recommendations in this article incorporate the grading system that is discussed in this supplement (Guyatt G et al, CHEST 2008; 133:123S-131S). Briefly, Grade 1 recommendations are considered strong and indicate that the benefits do (or do not) outweigh risks, burden, and costs, whereas Grade 2 recommendations are referred to as suggestions and imply that individual patient values may lead to different management choices. The key recommendations in this article include the following: in patients with a mechanical heart valve or atrial fibrillation or venous thromboembolism (VTE) at high risk for thromboembolism, we recommend bridging anticoagulation with therapeutic-dose subcutaneous (SC) LMWH or IV UFH over no bridging during temporary interruption of VKA therapy (Grade 1C); in patients with a mechanical heart valve or atrial fibrillation or VTE at moderate risk for thromboembolism, we suggest bridging anticoagulation with therapeutic-dose SC LMWH, therapeutic-dose IV UFH, or low-dose SC LMWH over no bridging during temporary interruption of VKA therapy (Grade 2C); in patients with a mechanical heart valve or atrial fibrillation or VTE at low risk for thromboembolism, we suggest low-dose SC LMWH or no bridging over bridging with

    The 8th International Conference on Non-Contact Atomic Force Microscopy, held in Bad Essen, Germany, from 15 18th August 2005, attracted a record breaking number of participants presenting excellent contributions from a variety of scientific fields. This clearly demonstrated the high level of activity and innovation present in the community of NC-AFM researchers and the continuous growth of the field. The strongest ever participation of companies for a NC-AFM meeting is a sign for the emergence of new markets for the growing NC-AFM community; and the high standard of the products presented at the exhibition, many of them brand-new developments, reflected the unbroken progress in technology. The development of novel technologies and the sophistication of known techniques in research laboratories and their subsequent commercialization is still a major driving force for progress in this area of nanoscience. The conference was a perfect demonstration of how progress in the development of enabling technologies can readily be transcribed into basic research yielding fundamental insight with an impact across disciplines. The NC-AFM 2005 scientific programme was based on five cornerstones, each representing an area of vivid research and scientific progress. Atomic resolution imaging on oxide surfaces, which has long been a vision for the catalysis community, appears to be routine in several laboratories and after a period of demonstrative experiments NC-AFM now makes unique contributions to the understanding of processes in surface chemistry. These capabilities also open up new routes for the analysis of clusters and molecules deposited on dielectric surfaces where resolution limits are pushed towards the single atom level. Atomic precision manipulation with the dynamic AFM left the cradle of its infancy and flourishes in the family of bottom-up fabrication nanotechnologies.

    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.

  1. Chemistry to music: Discovering how Music-based Teaching affects academic achievement and student motivation in an 8th grade science class

    McCammon, William Gavin Lodge, Jr.

    Teachers should have access to new and innovative tools in order to engage and motivate their students in the classroom. This is especially important as many students view school as an antiquated and dull environment - which they must seemingly suffer through to advance. School need not be a dreaded environment. The use of music as a tool for learning can be employed by any teacher to create an engaging and exciting atmosphere where students actively participate and learn to value their classroom experience. Through this study, a product and process was developed that is now available for any 8th grade science teacher interested in using music to enhance their content. In this study 8th grade students (n=41) in a public school classroom actively interacted with modern songs created to enhance the teaching of chemistry. Data were collected and analyzed in order to determine the effects that the music treatment had on student achievement and motivation, compared to a control group (n=35). Current literature provides a foundation for the benefits for music listening and training, but academic research in the area of using music as a tool for teaching content was noticeably absent. This study identifies a new area of research called "Music-based Teaching" which results in increases in motivation for 8th grade students learning chemistry. The unintended results of the study are additionally significant as the teacher conducting the treatment experienced newfound enthusiasm, passion, and excitement for her profession.

    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.

  4. What factors help or hinder the achievement of low SES students? An international comparison using TIMSS 2011 8th grade science data

    NASA Astrophysics Data System (ADS)

    Bruner, Justin L.

    Focusing on science from a cross-country perspective, this study explores the relationship between 8th grade science achievement and student, teacher, and school characteristics. More specifically, this study will pay special attention to low socio-economic status (SES) students and seek to understand why some disadvantaged students are able to have higher than expected achievement in science given their SES while other disadvantaged students are not able to achieve beyond what would be expected given their background. This study will explore the multi-level relationship between the characteristics of students, their teachers, their schools, and student achievement in science. While looking at students in classrooms and in schools, this work will create as precise as possible a measure of student SES by drawing on recommendations of an expert panel commissioned by the National Association of Educational Progress (NAEP) study. The study uses the most recent cycle (2011) of the Trends in International Math and Science Study (TIMSS), to strategically select a six-country sample from the 45 participating countries. This six-country sample was selected by using the country level achievement and the standard deviation of that achievement. This will create a sample that has a range of equality in achievement and strength in achievement. This allows for making comparisons both across and within countries to better understand variations in the factors of student performance, especially for disadvantaged students. This paper builds on the existing research around socio-economic status (SES) and achievement by exploring in more detail the conditions in schools and classrooms around the world that might magnify or reduce the effect of SES on student achievement. The analysis looks at these questions: "What conditions help low SES students achieve higher than what would be expected given their SES?" and "What conditions hinder low SES students to achieve at or below what would

    Purpose In addition to excess adiposity, low cardiorespiratory fitness (CRF) and low musculoskeletal fitness (MSF) are important independent risk factors for future cardio-metabolic disease in adolescents, yet global fitness surveillance in adolescents is poor. The objective of this study was to describe and investigate geographical variation in levels of health-related physical fitness, including CRF, MSF, body mass index (BMI), and waist circumference (WC) in Chilean 8th graders. Methods This cross-sectional study was based on a population-based, representative sample of 19,929 8th graders (median age = 14 years) in the 2011 National Physical Education Survey from Chile. CRF was assessed with the 20-meter shuttle run test, MSF with standing broad jump, and body composition with BMI and WC. Data were classified according to health-related standards. Prevalence of levels of health-related physical fitness was mapped for each of the four variables, and geographical variation was explored at the country level by region and in the Santiago Metropolitan Area by municipality. Results Girls had significantly higher prevalence of unhealthy CRF, MSF, and BMI than boys (p<0.05). Overall, 26% of boys and 55% of girls had unhealthy CRF, 29% of boys and 35% of girls had unhealthy MSF, 29% of boys and 44% of girls had unhealthy BMI, and 31% of adolescents had unhealthy WC. High prevalence of unhealthy fitness levels concentrates in the northern and middle regions of the country and in the North and Southwest sectors for the Santiago Metropolitan Area. Conclusion Prevalence of unhealthy CRF, MSF, and BMI is relatively high among Chilean 8th graders, especially in girls, when compared with global estimates. Identification of geographical regions and municipalities with high prevalence of unhealthy physical fitness presents opportunity for targeted intervention. PMID:25255442

    GPS geodetic measurements of 350-650 km baselines across the Pacific-North America plate boundary in the Gulf of California are presented. The analysis employs a four-station U.S. fiducial network and combined carrier phase and pseudorange data. Water vapor radiometer data at the Gulf sites are used to calibrate the GPS signal for wet tropospheric path delays. Residual tropospheric delays are modeled as first-order exponentially correlated stochastic processes. The measurement precision for horizontal components is a few parts in 10 to the 8th or better.

  8. Longitudinal Study of Career Cluster Persistence from 8th Grade to 12th Grade with a Focus on the Science, Technology, Engineering, & Math Career Cluster

    NASA Astrophysics Data System (ADS)

    Wagner, Judson

    Today's technology driven global economy has put pressure on the American education system to produce more students who are prepared for careers in Science, Technology, Engineering, and Math (STEM). Adding to this pressure is the demand for a more diverse workforce that can stimulate the development of new ideas and innovation. This in turn requires more female and under represented minority groups to pursue future careers in STEM. Though STEM careers include many of the highest paid professionals, school systems are dealing with exceptionally high numbers of students, especially female and under represented minorities, who begin but do not persist to STEM degree completion. Using the Expectancy-Value Theory (EVT) framework that attributes student motivation to a combination of intrinsic, utility, and attainment values, this study analyzed readily available survey data to gauge students' career related values. These values were indirectly investigated through a longitudinal approach, spanning five years, on the predictive nature of 8 th grade survey-derived recommendations for students to pursue a future in a particular career cluster. Using logistic regression analysis, it was determined that this 8 th grade data, particularly in STEM, provides significantly high probabilities of a 12th grader's average grade, SAT-Math score, the math and science elective courses they take, and most importantly, interest in the same career cluster.

Quantities obtained were the concentrations of hydrogen atoms, protons, free electrons, hydrogen molecules, negative hydrogen ions, hydrogen diatomic molecular ions, and hydrogen triatomic molecular ions, and the enthalpy, entropy, average molecular weight, specific heat at constant pressure, density, and isentropic exponent. Electronically excited states of H and H2 were included. Choked, isentropic, one-dimensional nozzle flow with shifting chemical equilibrium was calculated to the Debye-Huckel and ideal-gas approximations for stagnation temperatures from 2500 to 100,000 K. The mass flow per unit throat area and the sonic flow factor were obtained. The pressure ratio, temperature, velocity, and ideal and vacuum specific impulses at the throat and for pressure ratios as low as 0.000001 downstream were found. For high temperatures at pressures approaching 1.01325 x 10 to the 8th power N/sq m, the ideal-gas approximation was found to be inadequate for calculations of composition, precise thermodynamic properties, and precise nozzle flow. The greatest discrepancy in nozzle flow occurred in the exit temperature, which was as much as 21 percent higher when the Debye-Huckel approximation was used.

    , local properties of spacetime structure. The scope of this series of conferences is, however, much wider. There have been recent developments in the understanding of general relativity concerning questions associated with dark energy and the dark matter problem, the distribution of stars in galaxies, and the distribution of galaxies in the visible universe, as well as the internal structure of stars. There are, moreover fundamental questions in the applications of relativistic dynamics to physical problems, and in its mathematical and logical structure. It was for this purpose, to bring together researchers from a wide variety of fields, such as particle physics, astrophysics, cosmology, heavy ion collisions, plasma research, and mathematical physics, with a common interest in relativistic dynamics, that this Association was founded. The International Association for Relativistic Dynamics was organized at its first meeting as an informal session of seminars among researchers with common interest in February 1998 in Houston, Texas, with John R Fanchi as president. The second meeting took place, in 2000, at Bar Ilan University in Ramat Gan, Israel, the third, in 2002, at Howard University in Washington, D.C., and the fourth, on 12--19 June 2004, in Saas Fee, Switzerland. In 2006, the meeting took place at the University of Connecticut campus in Storrs, Connecticut, and the sixth meeting, in Thessaloniki, Greece. The seventh meeting took place at the National Dong Hwa University in Hualien, Taiwan from 30 May to 1 June 2010, and the eighth meeting, reported here, at the Galileo Galilei Institute for Theoretical Physics (GGI) in Florence, Italy, 29 May to 1 June 2012. This meeting forms the basis for the Proceedings of IARD 2012, recorded in this volume of Journal of Physics: Conference Series. Along with the work of some of the founding members of the Association, we were fortunate to have lecturers from application areas that provided strong challenges for further

    1998-09-01

    The South 8th Street Landfill Superfund Site (Site), CERCLIS ID No. ARD980496723, is located in West Memphis, Crittenden County, Arkansas. In the 1994 ROD, EPA divided the Site into a source control operable unit and a ground water operable unit. The source control operable unit contains an oily sludge pit, which is identified as a principal threat, and a landfill identified as a low-level threat. This ROD Amendment addresses both operable units by: (1) amending the remedy for the oily sludge pit area in the source control operable unit; (2) modifying the extent of the natural soil cover to be installed over the landfill in the source control operable unit; and (3) selecting a remedy for the ground water operable unit.

    This article is a report of the 8th Berlin Workshop on Developmental Toxicity held in May 2014. The main aim of the workshop was the continuing harmonization of terminology and innovations for methodologies used in the assessment of embryo- and fetotoxic findings. The following main topics were discussed: harmonized categorization of external, skeletal, visceral and materno-fetal findings into malformations, variations and grey zone anomalies, aspects of developmental anomalies in humans and laboratory animals, and innovations for new methodologies in developmental toxicology. The application of Version 2 terminology in the DevTox database was considered as a useful improvement in the categorization of developmental anomalies. Participants concluded that initiation of a project for comparative assessments of developmental anomalies in humans and laboratory animals could support regulatory risk assessment and university-based training. Improvement of new methodological approaches for alternatives to animal testing should be triggered for a better understanding of developmental outcomes.

    Objectives Understanding the similarities and differences between substance use rates for American Indian (AI) young people and young people nationally can better inform prevention and treatment efforts. We compared substance use rates for a large sample of AI students living on or near reservations for the years 2009–2012 with national prevalence rates from Monitoring the Future (MTF). Methods We identified and sampled schools on or near AI reservations by region; 1,399 students in sampled schools were administered the American Drug and Alcohol Survey. We computed lifetime, annual, and last-month prevalence measures by grade and compared them with MTF results for the same time period. Results Prevalence rates for AI students were significantly higher than national rates for nearly all substances, especially for 8th graders. Rates of marijuana use were very high, with lifetime use higher than 50% for all grade groups. Other findings of interest included higher binge drinking rates and OxyContin® use for AI students. Conclusions The results from this study demonstrate that adolescent substance use is still a major problem among reservation-based AI adolescent students, especially 8th graders, where prevalence rates were sometimes dramatically higher than MTF rates. Given the high rates of substance use-related problems on reservations, such as academic failure, delinquency, violent criminal behavior, suicidality, and alcohol-related mortality, the costs to members of this population and to society will continue to be much too high until a comprehensive understanding of the root causes of substance use are established.

    PubMed

    Sverdlov, E D

    2003-01-01

    A tremendous success in bacterial genome sequencing has been achieved during the recent years; it resulted in making available, for analysis, multiple sequences of different bacterial genomes, including such pathogens as causative agents of syphilis, typhus, and tuberculosis as well as such organisms like archaebacterias living under extreme conditions. A comparative analysis of bacterial genomes leads to conclusions, which have a general biological value, and, in particular, to the conclusions about mechanisms and evolution rate as well as about the variability of genomes and interrelation between organisms and their habitat. On the other hand, the analysis reveals specific features of separate bacterial species responsible for their pathogenicity and ability to avoid the destruction of the host immune system as well as for adaptation to exist within a certain ecological niche. However, the variability of bacterial genomes is so high that methods, which enable to evaluate the variability without full genome sequencing, are needed to depict adequately the evolution and ecological characteristics of the prokaryotic world and to develop new effective therapeutics and diagnostic tools. The survey covers two approaches to such comparative analysis, i.e. DNA arrays and subtractive hybridization. The advantages and disadvantages of each approach are discussed and the necessity in a new approach combining the positive features of the two mentioned approaches is substantiated.

    This study summarizes the effects of a strong coronal mass ejection (CME) on Mars as detected by Mars Atmosphere and Volatile Evolution Mission (MAVEN) in the solar wind and by Mars Express (MEX) in the nightside ionosphere. The Solar Wind Ion Analyzer (SWIA) onboard MAVEN identified a strong CME on March 8th, 2015, characterized by an increase in the solar wind density and solar wind speeds up to about 800 km/s. Simultaneously with the MAVEN observations, the Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) on MEX detected unusually high local electron density and local magnetic field values in the nightside Martian ionosphere. The Ion Mass Analyzer (IMA) on Analyzer of Space Plasmas and Energetic Atoms (ASPERA-3) instrument, also on MEX, saw a sharp CME front followed by an increase in the ion speed and a sharp enhancement in the electron flux seen by the ASPERA-3 Electron Spectrometer (ELS) signals the CME. ASPERA-3 data also suggest an increase in the plasma temperature when the shock hits Mars. Finally, the peak ionospheric density obtained with MARSIS remote sounding exhibits a discrete enhancement over a period of about 30 hrs around the same latitude and local time. We believe that this high density ionospheric plasma is forced by the CME from dayside to the nightside towards high altitudes.

  20. Increasing the complexity of young adolescents' beliefs about poverty and inequality: results of an 8th grade social studies curriculum intervention.

    Poverty and economic hardship remain a reality for many of America's children. Although the causes of poverty are varied, Americans strongly endorse individual responsibility as a primary cause. Because beliefs about poverty originate in childhood and adolescence, intervention efforts targeting young people may be particularly effective in shifting attitudes about the poor and policies designed to help the disadvantaged. To test this proposition, the current study evaluated the efficacy of a 1-week 8th grade social studies curriculum focusing on poverty and inequality. Study participants were upper middle-class youth enrolled in multiple sections of a Social Studies course taught by a single teacher. Participants had little direct contact with marginalized groups such as poor and homeless individuals in their communities. Students (N=66) completed a survey assessing their attitudes and beliefs about poverty and poor people prior to, and 1 week and 6 months post-instruction. Results indicated that the curriculum was partially effective in increasing the complexity of students' beliefs about poverty. Students were more likely to emphasize fatalistic causes and less likely to list individualistic causes for poverty following instruction than before, but rarely emphasized structural causes for poverty and rated individual effort as the most influential factor in determining one's success. Implications of the study findings for curriculum efforts targeting young adolescents' reasoning about economic inequality and inequity and directions for future studies are discussed.

  1. Self-diagnosis as a tool for supporting students’ conceptual understanding and achievements in physics: the case of 8th-graders studying force and motion

    I examined the impact of a self-diagnosis activity on students’ conceptual understanding and achievements in physics. This activity requires students to self-diagnose their solutions to problems that they have solved on their own—namely, to identify and explain their errors—and self-score them—that is, assign scores to their solutions—aided by a rubric demonstrating how to solve each problem step by step. I also examined a common practice in the physics classroom in which teachers manage a whole class discussion during which they solve, together with their students, problems that students had solved on their own. Three 8th-grade classes studying force and motion with the same teacher participated. Students were first taught the unit in force and motion. Then a first summative exam was administered. Next, two classes (59 students) were assigned to the self-diagnosis activity and the other class to the whole class discussion (27 students). To assess students’ learning with these activities, a repeat exam was administered. Results suggest that at least for teachers who are not competent in managing argumentative class discussions, the self-diagnosis activity is more effective than the whole class discussion in advancing students’ conceptual understanding and achievements. I account for these results and suggest possible directions for future research.

    The aim of the study was to explore the prevalence of different smoking habits in a population of Austrian pupils, 12 to 15 years old, and the relationship of familial and peer group smoking customs with these habits. In 1997 a population-based survey (International Study of Asthma and Allergies in Childhood, ISAAC) was conducted of all 7th and 8th grade school children of a district of Upper Austria. Information on the smoking habits of the adolescents, the family members, and of the peer as well as smoking habits of the teacher, gender, and age of the children was collected. The overall-prevalence of having ever smoked in this population is 57.8%. The percentage of eversmokers among the 12-year-olds is 50%. This amount increases to 63.8% among the 14- to 15-year-olds. The odds ratios for smoking daily is highest among those whose best friend smokes (OR: 70.63, CI: 9.19, 542.40). The risk of daily smoking increases also if the siblings of the juvenile (OR: 4.71, CI: 1.15, 19.35) or the mother (OR: 4.95, CI: 1.67, 14.70) smoke. If the father smokes the risk to smoke monthly is increased (OR: 2.09, CI: 1.28, 3.40). These results point to the fact that smoking prevention programes should take into account the influence of peers and family of the adolescents.

    The fungal pathogen Sclerotinia sclerotiorum causes stem rot of oilseed rape (Brassica napus) worldwide. In preparation for genome-wide association mapping (GWAM) of sclerotinia resistance in B. napus, 152 accessions from diverse geographical regions were screened with a single Canadian isolate, #321. Plants were inoculated by attaching mycelium plugs to the main stem at full flower. Lesion lengths measured 7, 14 and 21 days after inoculation were used to calculate the area under the disease progress curve (AUDPC). Depth of penetration was noted and used to calculate percent soft and collapsed lesions (% s + c). The two disease traits were highly correlated (r = 0.93). Partially resistant accessions (AUDPC <7 and % s + c <2) were identified primarily from South Korea and Japan with a few from Pakistan, China and Europe. Genotyping of accessions with 84 simple sequence repeat markers provided 690 polymorphic loci for GWAM. The general linear model in TASSEL best fitted the data when adjusted for population structure (STRUCTURE), GLM + Q. After correction for positive false discovery rate, 34 loci were significantly associated with both disease traits of which 21 alleles contributed to resistance, while the remaining enhanced susceptibility. The phenotypic variation explained by the loci ranged from 6 to 25 %. Five loci mapped to published quantitative trait loci conferring sclerotinia resistance in Chinese lines.

  4. From interaction to co-association --a Fisher r-to-z transformation-based simple statistic for real world genome-wide association study.

    Currently, the genetic variants identified by genome wide association study (GWAS) generally only account for a small proportion of the total heritability for complex disease. One crucial reason is the underutilization of gene-gene joint effects commonly encountered in GWAS, which includes their main effects and co-association. However, gene-gene co-association is often customarily put into the framework of gene-gene interaction vaguely. From the causal graph perspective, we elucidate in detail the concept and rationality of gene-gene co-association as well as its relationship with traditional gene-gene interaction, and propose two Fisher r-to-z transformation-based simple statistics to detect it. Three series of simulations further highlight that gene-gene co-association refers to the extent to which the joint effects of two genes differs from the main effects, not only due to the traditional interaction under the nearly independent condition but the correlation between two genes. The proposed statistics are more powerful than logistic regression under various situations, cannot be affected by linkage disequilibrium and can have acceptable false positive rate as long as strictly following the reasonable GWAS data analysis roadmap. Furthermore, an application to gene pathway analysis associated with leprosy confirms in practice that our proposed gene-gene co-association concepts as well as the correspondingly proposed statistics are strongly in line with reality.

    Seventy-seven animal isolates of Salmonella enterica serovar Enteritidis (S. Enteritidis) obtained from the United States were analyzed by phage typing and pulsed field gel electrophoresis (PFGE). Thirty-nine strains were found with phage types (PT) 4, 8, and 13a. When the chromosomal DNA of these 39 isolated strains with PT4, 8, and 13a were digested with XbaI, SpeI and NotI, followed by PFGE analysis, 28 strains were found with a pattern combination of X4S4N4, which was the major subtype. When PFGE patterns of the US isolates with PT 4 and 8 were compared with those of the Taiwanese and German isolates, pattern X3S3N3 was confirmed to be the world-wide subtype shared by PT 4 isolates, as previously reported, while pattern X4S4N4 was newly found to be the most common subtype shared by PT 8 strains. The presence of such major world-wide clones, however, does not necessarily mean that these clones are highly virulent, at least not according to the results of invasiveness assays using cultured human intestinal epithelium cell line Int-407 and living BALB/mice.

    1988-07-01

    Two field trips held in conjunction with the 8th International Conference on Basement Tectonics are the raison d'etre for this volume, which would perhaps otherwise seem an eclectic association. The unifying theme is an investigation of the nature of plate margins in time and space, consonant with the main theme of the conference, Characterization and Comparison of Precambrian Through Mesozoic Continental Margins. Papers presented at the conference will be published in a separate volume by the International Basement Tectonics Association, Inc. The first field trip is at least a preliminary attempt at an overview of the Precambrian (predominantly Archean) crystalline basement of southwestern Montana. A number of interesting investigations have been focused on this region in recent years. Thus, papers in the first part of this volume take the reader from the Stillwater Complex across the Beartooth Plateau, to the northern borders of Yellowstone National Park on to the southern Madison Range, and finally to some of the western-most (probable) Archean exposures in the Highland Mountains south of Butte. Moving considerably forward on the geologic time scale, the other broad topic dealt with in a second field trip and complementary articles is a relatively recent collisional terrane in central Idaho and eastern Oregon. Examined are portions of the Idaho batholith and its enigmatic and fascinating marginal rocks, and to the west, the heart of the suture zone itself in the Wallowa-Seven Devils terrane with its group of exotic intrusive, metavolcanic, and metasedimentary rocks. Individual papers are processed separately for the data base.

    Although most faults are surrounded by a halo of fractured rock known as a damage zone, it is not clear what role damage zones play during the seismic cycle on mature faults. Here, we present a superbly-located foreshock-mainshock-aftershock sequence surrounding the November 8, M5 Prague Oklahoma earthquake, which demonstrates most aftershocks are located within the damage zone surrounding the fault. The 2011 Prague, Oklahoma sequence included three M5+ earthquakes along three different faults over a three-day period. The November 8th event was third in the sequence and captured with an array of nine seismometers with ~2 km spacing, allowing for precise event location. We located more than 1000 foreshocks and aftershocks within a 14 hour time window, and relocated these aftershocks using waveform cross correlation and HypoDD. Because of the location precision, we can use these events to investigate spatial and temporal complexity of the foreshock and aftershock sequences. First, we compare the aftershock distribution to fracture distributions within damage zones surrounding faults. The aftershock sequence localizes to a reasonable damage zone thickness given the rupture length of the event, according to previously documented scaling between fault length and damage zone thickness. Furthermore, the aftershock density is constant within the fault zone, but falls off precipitously outside of the damage zone. Most aftershocks in this sequence occur within the first hour after the mainshock, and there is some indication of temporal migration of aftershocks away from the fault. Finally, foreshock activity along this fault was limited to the intersection with the fault that had hosted a M5.7 earthquake two days prior. Because this earthquake is potentially linked to fluid waste disposal, we interpret our results in terms of hydraulic pressure changes during the foreshock-mainshock-aftershock sequence.

  10. Reflection on solutions in the form of refutation texts versus problem solving: the case of 8th graders studying simple electric circuits

    This study compared students’ learning in troubleshooting and problem solving activities. The troubleshooting activities provided students with solutions to conceptual problems in the form of refutation texts; namely, solutions that portray common misconceptions, refute them, and then present the accepted scientific ideas. They required students to individually diagnose these solutions; that is, to identify the erroneous and correct parts of the solutions and explain in what sense they differed, and later share their work in whole class discussions. The problem solving activities required the students to individually solve these same problems, and later share their work in whole class discussions. We compared the impact of the individual work stage in the troubleshooting and problem solving activities on promoting argumentation in the subsequent class discussions, and the effects of these activities on students’ engagement in self-repair processes; namely, in learning processes that allowed the students to self-repair their misconceptions, and by extension on advancing their conceptual knowledge. Two 8th grade classes studying simple electric circuits with the same teacher took part. One class (28 students) carried out four troubleshooting activities and the other (31 students) four problem solving activities. These activities were interwoven into a twelve lesson unit on simple electric circuits that was spread over a period of 2 months. The impact of the troubleshooting activities on students’ conceptual knowledge was significantly higher than that of the problem solving activities. This result is consistent with the finding that the troubleshooting activities engaged students in self-repair processes whereas the problem solving activities did not. The results also indicated that diagnosing solutions to conceptual problems in the form of refutation texts, as opposed to solving these same problems, apparently triggered argumentation in subsequent class

    In 2010 a group of 8th grade geoscience students participated in an extracurricular activity allowing them to conduct original scientific research while being mentored by students enrolled in a 3 - year high school Science Research program. Upon entering high school the mentored students themselves enrolled in the Science Research program and continued for 4 years, culminating with their participation in Science Research 4. This allowed them to continue conducting original scientific research, act as mentors to 8th grade geoscience students and to provide teacher training for both middle and high school teachers conducting inquiry-based science lessons. Of the 7 Science Research 4 students participating since 2010, 100% plan on majoring or minoring in a STEM - related field in college and their individual research projects have been been granted over 70 different awards and honors in science fair and symposia including a 3rd and 4th place category awards at two different international science fairs - the International Sustainable Energy Engineering and Environment Project (iSWEEP) and the International Science and Engineering Fair (ISEF). Science Research 4 students developed and conducted a Society for Science and the Public affiliated science fair for middle school students enrolled in an 8th grade honors geoscience program allowing over 100 students from 5 middle schools to present their research and be judged by STEM professionals. Students with research judged in the top 10% were nominated for participation in the National Broadcom MASTERS program which they successfully entered upon further mentoring from the Science Research 4 students. 8th grade enrollment in the Science Research program for 2015 increased by almost 50% with feedback from students, parents and teachers indicating that the mentorship and participation in the 8th grade science fair were factors in increasing interest in continuing authentic scientific research in high school.

    Background The incidence of vaccine-preventable diseases is directly related to the number of unvaccinated children. Parents who refuse vaccination of their children frequently express concerns about vaccine safety. The Internet can influence perceptions about vaccines because it is the fastest growing source of consumer health information. However, few studies have analyzed vaccine criticism on the Web. Objective The purposes of this paper are to examine vaccine criticism on the Internet and to analyze the websites in order to identify common characteristics and ethical allegations. Methods A structured Web search was conducted for the terms “vaccine,” “vaccination,” “vaccinate,” and “anti-vaccination” using a metasearch program that incorporated 8 search engines. This yielded 1138 Web pages representing 750 sites. Two researchers reviewed the sites for inclusion/exclusion criteria, resulting in 78 vaccine-critical sites, which were then abstracted for design, content, and allegations. Results The most common characteristic of vaccine-critical websites was the inclusion of statements linking vaccinations with specific adverse reactions, especially idiopathic chronic diseases such as multiple sclerosis, autism, and diabetes. Other common attributes (≥ 70% of websites) were links to other vaccine-critical websites; charges that vaccines contain contaminants, mercury, or “hot lots” that cause adverse events; claims that vaccines provide only temporary protection and that the diseases prevented are mild; appeals for responsible parenting through education and resisting the establishment; allegations of conspiracies and cover-ups to hide the truth about vaccine safety; and charges that civil liberties are violated through mandatory vaccination. Conclusions Vaccine-critical websites frequently make serious allegations. With the burgeoning of the Internet as a health information source, an undiscerning or incompletely educated public may accept these claims and refuse vaccination of their children. As this occurs, the incidence of vaccine-preventable diseases can be expected to rise. PMID:15998608

  19. Critical care and the World Wide Web.

    1999-07-01

    The Internet was created in 1969, when the Advanced Research Projects Agency of the United States Department of Defense fired up an experimental network consisting of only four computers. Over the past five years there has been an exponential explosion in the number of computers added to this network. It is estimated that Internet traffic doubles every 100 days with more than 100 million people worldwide now on-line. The Internet is so vast that practically every aspect of human interest is represented is some form or fashion. From recreation to applied science and technology, and from Critical Care Medicine case scenarios to digitized radiology images and pathology specimens, the Internet has become increasingly useful for critical care practitioners. To date, no resource is better equipped to assist critical care providers in many of their daily tasks. This article presents some of the historical developments of the Internet as well as common applications that are useful for critical care practitioners.

  20. Sun protection factors: world wide confusion.

    The Sun Protection Factor (SPF) is a very popular instrument in the marketing of sunscreens. Unfortunately it is often not understood how sunscreens work and where the limitations of the SPF are. A lot of aspects of the SPF are confusing, e.g. the race for higher and higher numbers, the effect on SPF when less sunscreen is applied and if sunscreen should be used at all because they may block the Vitamin D synthesis. All this has a negative impact on compliance by the consumer or patient which is the most important influence factor in sun protection. This paper explains how sunscreens work, how the SPF is determined and where the limitations of the current methods exist. The dynamic view of 'UV radiation applied' and the 'UV dose transmitted' through the sunscreen onto the skin as well as onto a substrate in vitro help in the understanding and are also promising approaches in the in vitro assessment. A variation of the in vitro assessment of a sunscreen is the in silico calculation based on the absorption spectrum of the UV filters and an assumption about the irregular sunscreen film on the skin. The sunscreen simulator program can be used to determine how the SPF is affected by applying smaller amounts of sunscreen. Besides the SPF, UVA protection is also discussed. The degree of UVA protection determines the quality of the overall UV protection, whereas the SPF is an indication of the quantity of protection. Furthermore other protection factors such as IPF, iSPF, RSF and p53, and the inhibition of the Vitamin D3 synthesis by sunscreens are also discussed. In conclusion it is shown that the accuracy and robustness of the SPF and other Protection Factors will improve significantly with the availability of true broad-spectrum sunscreens rather than conventional UVB-biased sunscreens, because uniform protection profiles lead to protection independent of the action spectrum of the endpoint and the UV-radiation source.

    The supercritical water-cooled reactor (SCWR) is one of the six reactor technologies selected for research and development under the Generation-IV program. SCWRs are promising advanced nuclear systems because of their high thermal efficiency (i.e., about 45% vs. about 33% efficiency for current Light Water Reactors, LWRs) and considerable plant simplification. SCWRs are basically LWRs operating at higher pressure and temperatures with a direct once-through cycle. Operation above the critical pressure eliminates coolant boiling, so the coolant remains single-phase throughout the system. Thus the need for recirculation and jet pumps, a pressurizer, steam generators, steam separators and dryers is eliminated. The main mission of the SCWR is generation of low-cost electricity. It is built upon two proven technologies, LWRs, which are the most commonly deployed power generating reactors in the world, and supercritical fossil-fired boilers, a large number of which is also in use around the world.

    This special issue of the Journal of Micromechanics and Microengineering features papers selected from The 8th International Workshop on Micro and Nanotechnology for Power Generation and Energy Conversion Applications (PowerMEMS 2008) with the 2nd Symposium on Micro Environmental Machine Systems (μMEMS 2008). The workshop was held in Sendai, Japan on 9-12 November 2008 by Tohoku University. This is the second time that the PowerMEMS workshop has been held in Sendai, following the first workshop in 2000. Power MEMS is one of the newest categories of MEMS, which encompasses microdevices and microsystems for power generation, energy conversion and propulsion. The first concept of Power MEMS was born in the late 1990's from a MEMS-based gas turbine project at Massachusetts Institute of Technology. After that, the research and development of Power MEMS have been promoted by the strong need for compact power sources with high energy and/or power density. Since its inception, Power MEMS has expanded to include not only various MEMS-based power generators but also small energy machines and microdevices for macro power generators. Previously, the main topics of the PowerMEMS workshop were miniaturized gas turbines and micro fuel cells, but recently, energy harvesting has been the hottest topic. In 2008, energy harvesting had a 41% share in the 118 accepted regular papers. This special issue includes 19 papers on various topics. Finally, I would like to express my sincere appreciation to the members of the International Steering Committee, the Technical Program Committee, the Local Organizing Committee and financial supporters. This special issue was edited in collaboration with the staff of IOP Publishing.

    This chapter reports the wide range of ideas in a pair of major scientific conference meetings held inside the most popular virtual world, World of Warcraft (WoW), May 9 and May 10, 2008, plus the challenges of organizing these online events. More than a hundred scholars and scientists contributed to each session, the first covering research on World of Warcraft, and the second examining how virtual worlds fit into the larger world of human experience. A third session, held on May 11, was the starting point for the concluding chapter of this volume. This chapter describes how WoW and other virtual worlds can be used as laboratories for studying human behavior, using both qualitative and quantitative methodologies, and the affordances of virtual worlds can be used to support scientific communication (Bainbridge 2007, in press).

    Although national and state estimates of child obesity are available, data at these levels are insufficient to monitor effects of local obesity prevention initiatives. The purpose of this study was to examine regional changes in the prevalence of obesity due to statewide policies and programs among children in grades 4, 8, and 11 in Texas Health Services Regions (HSRs) between 2000-2002 and 2004-2005, and nine selected counties in 2004-2005. A cross-sectional, probability-based sample of 23,190 Texas students in grades 4, 8, and 11 were weighed and measured to obtain BMI. Obesity was >95th percentile for BMI by age/sex using Centers for Disease Control and Prevention growth charts. Child obesity prevalence significantly decreased between 2000-2002 and 2004-2005 for 4th grade students in the El Paso HSR (-7.0%, P = 0.005). A leveling off in the prevalence of obesity was noted for all other regions for grades 4, 8, and 11. County-level data supported the statistically significant decreases noted in the El Paso region. The reduction of child obesity levels observed in the El Paso area is one of the few examples of effective programs and policies based on a population-wide survey: in this region, a local foundation funded extensive regional implementation of community programs for obesity prevention, including an evidence-based elementary school-based health promotion program, adult nutrition and physical activity programs, and a radio and television advertising campaign. Results emphasize the need for sustained school, community, and policy efforts, and that these efforts can result in decreases in child obesity at the population level.

    At Amaldi7,which was held in Sydney in 2007, the Gravitational Wave International Committee (GWIC), which oversees the Amaldi meetings, decided to hold the 8th Edoardo Amaldi Conference on Gravitational Waves at Columbia University in the City of New York. With this decision, Amaldi returned to North America after a decade. The previous two years have seen many advances in the field of gravitational-wave detection. By the summer of 2009 the km-scale ground based interferometric detectors in the USA and Europe were preparing for a second long-term scientific run as a worldwide detector network. The advanced or second-generation detectors had well-developed plans and were ready for the production phase or had started construction. The European-American space mission, LISA Pathfinder, is progressing towards deployment in the foreseeable future and it is expected to pave the way towards gravitational-wave detection in the millihertz regime with LISA. Plans were developed for an additional gravitational-wave detector in Australia and in Japan (in this case underground) to extend the worldwide network of detectors for the advanced detector era. Japanese colleagues also presented plans for a space mission, DECIGO, that would bridge the gap between the LISA and ground-based interferometer frequency range. Compared to previous Amaldi meetings, Amaldi8 had new elements representing emerging trends in the field. For example, with the inclusion of pulsar timing collaborations to the GWIC, gravitational-wave detection using pulsar timing arrays was recognized as one of the prominent directions in the field and was represented at Amaldi8 as a separate session. By 2009, searches for gravitational waves based on external triggers received from electromagnetic observations were already producing significant scientific results and plans existed for pointing telescopes by utilizing gravitational-wave trigger events. Such multimessenger approaches to gravitational-wave detection also

    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.

    The diagnosis of Waldenström macroglobulinaemia (WM) can be challenging given the variety of signs and symptoms patients can present. Furthermore, once the diagnosis of WM is established, the initial evaluation should be thorough as well as appropriately directed. During the 8th International Workshop for WM in London, United Kingdom, a multi-institutional task force was formed to develop consensus recommendations for the diagnosis and initial evaluation of patients with WM. In this document, we present the results of the deliberations that took place to address these issues. We provide recommendations for history-taking and physical examination, laboratory studies, bone marrow aspiration and biopsy analysis and imaging studies. We also provide guidance on the initial evaluation of special situations, such as anaemia, hyperviscosity, neuropathy, Bing-Neel syndrome and amyloidosis. We hope these recommendations serve as a practical guidance to clinicians taking care of patients with a suspected or an established diagnosis of WM.
