2018-01-01

August 21, 2017, the Citizen Continental-America Telescopic Eclipse(CATE) Experiment observed the 2017 total solar eclipse using a network of 68 identical telescopes and camera systems along the path of totality. The result from the observation was over 90% of all sites collected totality data on the day of the eclipse. Since the volunteers had to remove the solar filter manually, there is an uncertainty between the time of totality and data acquired during totality. Some sites also experienced cloudy weather which obscured the eclipse in some of the exposures but had small breaks in the clouds during the observation, collecting clear totality data. Before we can process and analyze the eclipse data, we must carefully determine which frames cover the time of totality for each site and remove exposures with clouds blocking the FOV. In this poster, we will discuss the techniques we used to determine the extent of totality from each location using the logged GPS data and the removal of totality exposure with clouds.

On the detection and attribution of gravity waves generated by the 20 March 2015 solar eclipse

PubMed Central

2016-01-01

Internal gravity waves are generated as adjustment radiation whenever a sudden change in forcing causes the atmosphere to depart from its large-scale balanced state. Such a forcing anomaly occurs during a solar eclipse, when the Moon’s shadow cools part of the Earth’s surface. The resulting atmospheric gravity waves are associated with pressure and temperature perturbations, which in principle are detectable both at the surface and aloft. In this study, surface pressure and temperature data from two UK sites at Reading and Lerwick are examined for eclipse-driven gravity wave perturbations during the 20 March 2015 solar eclipse over northwest Europe. Radiosonde wind data from the same two sites are also analysed using a moving parcel analysis method, to determine the periodicities of the waves aloft. On this occasion, the perturbations both at the surface and aloft are found not to be confidently attributable to eclipse-driven gravity waves. We conclude that the complex synoptic weather conditions over the UK at the time of this particular eclipse helped to mask any eclipse-driven gravity waves. This article is part of the themed issue ‘Atmospheric effects of solar eclipses stimulated by the 2015 UK eclipse’. PMID:27550763

I discuss ongoing plans and discussions for EPO and scientific observing of the 21 August 2017 total solar eclipse. I discuss aspects of EPO based on my experiences at the 60 solar eclipses I have seen. I share cloud statistics along the eclipse path compiled by Jay Anderson, the foremost eclipse meteorologist. I show some sample observations of composite imagery, of spectra, and of terrestrial temperature changes based on observations of recent eclipses, including 2012 from Australia and 2013 from Gabon. Links to various mapping sites of totality, partial phases, and other eclipse-related information, including that provided by Michael Zeiler, Fred Espenak (retired from NASA) and Xavier Jubier can be found on the website I run for the International Astronomical Union's Working Group on Eclipses at http://www.eclipses.info.

Use of the Nebraska Mesonet to Engage the Public in the 2017 Eclipse Event

Cooper, S. R.; Richter-Ryerson, S.; Shulski, M.; Roebke, G.

2017-12-01

The 21 August 2017 Solar Eclipse promises to be the best observable solar eclipse for the Great Plains of the United States in recent history. The Nebraska State Climate Office has embarked upon a campaign of combining real-time Nebraska Mesonet observations, specifically shortwave downward radiation, with GOES-16 multispectral imagery, and social media solicited citizen images of the event to provide a multiple faceted record of the event. Providing a real-time view of the eclipse via satellite imagery and pyranometer output for web users will act as a hook to solicit images and testimonial from observers in the Great Plains to help enhance the record. The desired result is to provide excitement in the science of what is happening, along with promotion of the Nebraska State Climate Office and the services it provides.

NEWS: Eye safety and the solar eclipse

NASA Astrophysics Data System (ADS)

LeConte, David

1999-05-01

Total eclipses of the Sun are amongst nature's most magnificent spectacles, and offer the opportunity for an exceptional educational experience. Many people never see one in their lifetime, but it has been estimated that this August's eclipse will be seen by more people than any other. It would be a sadly lost opportunity if they were denied the experience because they fear a danger that is easily avoided. The dangers of eye damage are real and precautions need to be taken. Staring at the bright solar photosphere can cause temporary or permanent retinal damage. Since the retina has no pain receptors the observer can be unaware that the eye is being `cooked', and the damage may only become apparent several hours later. However, when the photosphere is completely blocked by the Moon during the brief period of totality (two minutes or less), it is quite safe to look directly. In fact, you will not otherwise see anything at all. It is a complex message to get across to the public, and especially to children, that protection is required during the partial phases but not during totality, and that those outside the path of totality require protection for the whole eclipse. The National Eclipse Group was established by PPARC in 1997 to coordinate educational activities, issue public information and give authoritative advice for the 1999 eclipse. It has published a Solar Eclipse Safety Code, which is available on the national eclipse web site (mentioned above). It advises that the safest way to view the Sun is indirectly, by projecting an image of the Sun with a `pinhole', mirror, binoculars or telescope. Most people, however, will wish to observe the eclipse directly. Sunglasses, photographic film, crossed polarizers, smoked glass and similar filters must not be used. The Safety Code states that the Sun may be viewed directly only through special filters made specifically for solar viewing. Such eclipse viewers are typically made of aluminized polyester film (often generically referred to as `aluminized Mylar') or polymer. Users should ensure that they are marked as having been supplied specifically for direct viewing of the Sun and carry the `CE' mark. To be awarded CE certification, the viewers must be tested in the visual, infrared and ultraviolet by Approved Bodies appointed by the Secretary of State for Trade and Industry, and they must pass a standard based on a specification prepared by Dr B Ralph Chou, University of Waterloo, Canada (see http://sunearth.gsfc.nasa.gov/eclipse/safety2.html). Any method of solar eclipse observation, whether direct or indirect, is not without its hazards. Severe eye damage can be caused, for example, by looking through a pinhole, rather than at the projected image, and will certainly result from looking through any optical instrument. Eclipse viewers should be placed over the eyes before looking up at the Sun and not removed until after looking away. Whatever method is used, children must be clearly instructed and closely supervised. Eclipse viewers are probably not appropriate for very young children. Descriptions of observing methods are in the activities packs for primary and secondary schools prepared by the Association for Astronomy Education and are available from CLEAPSS Schools Science Service and the National Eclipse Line (0345 600444).

EE Cep observations requested for upcoming eclipse

NASA Astrophysics Data System (ADS)

Waagen, Elizabeth O.

2014-07-01

The AAVSO requests observations for the upcoming eclipse of EE Cephei, a long-period eclipsing variable. EE Cep has a period of 2,050 days, and shows strong variations in the eclipse light curve from one event to the next. Observations are needed to study the morphology of the upcoming eclipse, which will be used to better understand the shape of the eclipsing disk and how it precesses. Mid-eclipse is predicted to be August 23, 2014, but the early stages of the eclipse may begin as much as a month earlier. EE Cep is being observed by a number of amateur and professional astronomers using multiple telescopes at multiple wavelengths. Among these is a collaboration (see https://sites.google.com/site/eecep2014campaign/) headed by Cezary Galan at the Nicolaus Copernicus Astronomical Center in Poland; several individual AAVSO observers are already participating in this effort. The AAVSO is not currently a partner in that campaign, but all data submitted to the AAVSO will be publicly available. The AAVSO strongly encourages observers to begin following this star now, and to continue observations into October 2014 at least. Finder charts with sequence may be created using the AAVSO Variable Star Plotter (http://www.aavso.org/vsp). Observations should be submitted to the AAVSO International Database. See full Alert Notice for more details and observations.

Thermal measurements were made in the 10 to 12 micron band of the lunar surface during the total eclipse of December19, 1964. A normalized differential thermal contour map is included, showing the location of the thermal anomalies or hot spots on the disk and the eclipse cooling curves of 400 sites, of which more than 300 were hot spots. The eclipse cooling data is compared to a particulate thermophysical model of the soil.

Evaluating the Eclipse: How good was it?

Noel-Storr, Jacob; InsightSTEM Evaluation Team

2018-01-01

We present findings from the evaluation program carried out of education, public outreach, and communication activities around the "Great American Eclipse" of August 21, 2017. We include findings drawn from the experiences of 30 participants in planning activities prior to the eclipse and 31 recipients of mini-grants for eclipse activities supported by the American Astronomical Society through a grant from the National Science Foundation. We synthesize evaluations gathered by these and other volunteering organizations to provide a multi-site picture of experiences and learning outcomes at eclipse-related events - both in the path of totality and in partial eclipse settings. We make use of qualitative and quantitative responses representing over 30,000 individuals who observed (or tried to observe) the eclipse. We will share findings from across the range of programs included in our evaluation network along with specific highlights. We emphasize a reflection on the motivation and activity behind the 2017 eclipse, and how to leverage the lessons learned for future events on this scale (such as the eclipse of April 8, 2024) along with messages relevant to other events connected with astronomical phenomena, or in multi-site settings.This work was supported in part by the National Science Foundation under Grant No. 1564535 awarded to the American Astronomical Society.

Adams, Mitzi L.; Gallagher, D. L.; Koczor, R. J.; Whitaker, Ann F. (Technical Monitor)

2001-01-01

For the last several years the Science Directorate at Marshall Space Flight Center has carried out a diverse program of Internet-based science communication. The Directorate's Science Roundtable includes active researchers, NASA public relations, educators, and administrators. The Science@NASA award-winning family of Web sites features science, mathematics, and space news. The program includes extended stories about NASA science, a curriculum resource for teachers tied to national education standards, on-line activities for students, and webcasts of real-time events. Science stories cover a variety of space-related subjects and are expressed in simple terms everyone can understand. The sites address such questions as: what is space weather, what's in the heart of a hurricane, can humans live on Mars, and what is it like to live aboard the International Space Station? Along with a new look, the new format now offers articles organized by subject matter, such as astronomy, living in space, earth science or biology. The focus of sharing real-time science related events has been to involve and excite students and the public about science. Events have involved meteor showers, solar eclipses, natural very low frequency radio emissions, and amateur balloon flights. In some cases broadcasts accommodate active feedback and questions from Internet participants. Information will be provided about each member of the Science@NASA web sites.

Lesniak, Michael V.; Pozniak, Daniel; Punnoose, Tarun

2015-01-01

The U.S. Naval Observatory (USNO) is in the process of modernizing its publicly available web services into APIs (Application Programming Interfaces). Services configured as APIs offer greater flexibility to the user and allow greater usage. Depending on the particular service, users who implement our APIs will receive either a PNG (Portable Network Graphics) image or data in JSON (JavaScript Object Notation) format. This raw data can then be embedded in third-party web sites or in apps.Part of the USNO's mission is to provide astronomical and timing data to government agencies and the general public. To this end, the USNO provides accurate computations of astronomical phenomena such as dates of lunar phases, rise and set times of the Moon and Sun, and lunar and solar eclipse times. Users who navigate to our web site and select one of our 18 services are prompted to complete a web form, specifying parameters such as date, time, location, and object. Many of our services work for years between 1700 and 2100, meaning that past, present, and future events can be computed. Upon form submission, our web server processes the request, computes the data, and outputs it to the user.Over recent years, the use of the web by the general public has vastly changed. In response to this, the USNO is modernizing its web-based data services. This includes making our computed data easier to embed within third-party web sites as well as more easily querying from apps running on tablets and smart phones. To facilitate this, the USNO has begun converting its services into APIs. In addition to the existing web forms for the various services, users are able to make direct URL requests that return either an image or numerical data.To date, four of our web services have been configured to run with APIs. Two are image-producing services: "Apparent Disk of a Solar System Object" and "Day and Night Across the Earth." Two API data services are "Complete Sun and Moon Data for One Day" and "Dates of Primary Phases of the Moon." Instructions for how to use our API services as well as examples of their use can be found on one of our explanatory web pages and will be discussed here.

The purpose of the Nationwide Eclipse Ballooning Project is to make the most of the 2017 rare eclipse event in four main areas: public engagement, workforce development, partnership development, and science. The Project is focused on two efforts, both student-led: online live video of the eclipse from the edge of space and the study of the atmospheric response to the eclipse. These efforts, however, involving more than 60 teams across the US, are challenging in many ways. Therefore, the Project is leveraging the NASA Space Grant and NOAA atmospheric science communities to make it a success. The first and primary topic of this poster is the NASA Space Grant supported online live video effort. College and high school students on 48 teams from 31 states will conduct high altitude balloon flights from 15-20 locations across the 8/21/2017 total eclipse path, sending live video and images from near space to a national website. Video and images of a total solar eclipse from near space are fascinating and rare. It’s never been done live and certainly not in a network of coverage across a continent. In addition to the live video to the web, these teams are engaged in several other science experiments as secondary payloads. We also briefly highlight the eclipse atmospheric science effort, where about a dozen teams will launch over one hundred radiosondes from across the 2017 path, recording an unprecedented atmospheric data sample. Collected data will include temperature, density, wind, humidity, and ozone measurements.

Effects of vernal equinox solar eclipse on temperature and wind direction in Switzerland

NASA Astrophysics Data System (ADS)

Eugster, Werner; Emmel, Carmen; Wolf, Sebastian; Buchmann, Nina; McFadden, Joseph P.; Whiteman, Charles David

2017-12-01

The vernal equinox total solar eclipse of 20 March 2015 produced a maximum occultation of 65.8-70.1 % over Switzerland during the morning hours (09:22 to 11:48 CET). Skies were generally clear over the Swiss Alps due to a persistent high-pressure band between the UK and Russia associated with a rather weak pressure gradient over the continent. To assess the effects of penumbral shading on near-surface meteorology across Switzerland, air temperature data measured at 10 min intervals at 184 MeteoSwiss weather stations were used. Wind speed and direction data were available from 165 of these stations. Additionally, six Swiss FluxNet eddy covariance flux (ECF) sites provided turbulent measurements at 20 Hz resolution. During maximum occultation, the temperature drop was up to 5.8 K at a mountain site where cold air can pool in a topographic depression. The bootstrapped average of the maximum temperature drops of all 184 MeteoSwiss sites during the solar eclipse was 1.51 ± 0.02 K (mean ± SE). A detailed comparison with literature values since 1834 showed a temperature decrease of 2.6 ± 1.7 K (average of all reports), with extreme values up to 11 K. On fair weather days under weak larger-scale pressure gradients, local thermo-topographic wind systems develop that are driven by small-scale pressure and temperature gradients. At one ECF site, the penumbral shading delayed the morning transition from down-valley to up-valley wind conditions. At another site, it prevented this transition from occurring at all. Data from the 165 MeteoSwiss sites measuring wind direction did not show a consistent pattern of wind direction response to the passing of the penumbral shadow. These results suggest that the local topographic setting had an important influence on the temperature drop and the wind flow patterns during the eclipse. A significant cyclonic effect of the passing penumbral shadow was found in the elevation range ≈ 1700-2700 m a. s. l., but not at lower elevations of the Swiss Plateau. This contrasts with an earlier theory that the anticyclonic outflow should reach as far as ≈ 2400 km from the center of the eclipse, which would have included all of Switzerland during the 2015 eclipse. Thus, measurable effects of penumbral shading on the local wind system could be even found at ≈ 2000 km from the path of the eclipse (that is, Switzerland during the 2015 eclipse), and our results tend to lend support to a newer theory that the anticyclonic cold-air outflow from the center of the eclipse only extends ≈ 1600 km outwards, with cyclonic flow beyond that distance.

We describe a student-led project to image two seventh-magnitude stars on either side of the Sun during the solar eclipse of August 21, 2017. Both stars were within one solar radius of the Sun, and according to Einstein’s theory of General Relativity, their positions would have been shifted away from the Sun by 1 arcsec. We observed the eclipse from three different sites along the path of totality (Lexington, South Carolina; Indian Valley, Idaho; Madras, Oregon). All three sites were clear, but the brightness of the solar corona has complicated the analysis. We present preliminary results using our best images from the site in Idaho.

The solar corona through the sunspot cycle: preparing for the August 21, 2017, total solar eclipse

We discuss the evolution of the solar corona as seen at eclipses through the solar-activity cycle. In particular, we discuss the variations of the overall shape of the corona through the relative proportions of coronal streamers at equatorial and other latitudes vs. polar plumes. We analyze the two coronal mass ejections that we observed from Gabon at the 2013 total solar eclipse and how they apparently arose from polar crown filaments, one at each pole. We describe the change in the Ludendorff flattening index from solar maximum in one hemisphere as of the 2013 eclipse through the 2015 totality's corona we observed from Svalbard and, with diminishing sunspot and other magnetic activity in each hemisphere, through the 2016 corona we observed from Ternate, Indonesia.We discuss our observational plans for the August 21, 2017, total solar eclipse from our main site in Salem, Oregon, and subsidiary sites in Madras, OR; Carbondale, IL; and elsewhere, our main site chosen largely by its favorable rating in cloudiness statistics. We discuss the overlapping role of simultaneous spacecraft observations, including those expected not only from NASA's SDO, ESA's SWAP on PROBA2, and NRL/NASA/ESA's LASCO on SOHO but also from the new SUVI (Solar Ultraviolet Imager) aboard NOAA's GOES-R satellite, scheduled as of this writing to have been launched by the time of this January 2017 meeting.Our research on the 2013 and 2015 total solar eclipses was supported by grants from the Committee for Research and Exploration of the National Geographic Society (NG-CRE). Our research on the 2017 total solar eclipse is supported by both NG-CRE and the Solar Terrestrial Program of the Atmospheric and Geospace Sciences Division of the National Science Foundation.

Observations of the eclipsing binary b Persei

Templeton, Matthew R.

2015-01-01

Dr. Robert Zavala (USNO-Flagstaff) et al. request V time-series observations of the bright variable star b Persei 7-21 January 2015 UT, in hopes of catching a predicted eclipse on January 15. This is a follow-up to the February 2013 campaign announced in Alert Notice 476, and will be used as a photometric comparison for upcoming interferometric observations with the Navy Precision Optical Interferometer (NPOI) in Arizona. b Per (V=4.598, B-V=0.054) is ideal for photoelectric photometers or DSLR cameras. Telescopic CCD observers may observe by stopping down larger apertures. Comparison and check stars assigned by PI: Comp: SAO 24412, V=4.285, B-V = -0.013; Check: SAO 24512, V=5.19, B-V = -0.05. From the PI: "[W]e wanted to try and involve AAVSO observers in a follow up to our successful detection of the b Persei eclipse of Feb 2013, AAVSO Alert Notice 476 and Special Notice 333. Our goal now is to get good time resolution photometry as the third star passes in front of the close ellipsoidal binary. The potential for multiple eclipses exists. The close binary has a 1.5 day orbital period, and the eclipsing C component requires about 4 days to pass across the close binary pair. The primary eclipse depth is 0.15 magnitude. Photometry to 0.02 or 0.03 mags would be fine to detect this eclipse. Eclipse prediction date (JD 2457033.79 = 2015 01 11 UT, ~+/- 1 day) is based on one orbital period from the 2013 eclipse." More information is available at PI's b Persei eclipse web page: http://inside.warren-wilson.edu/~dcollins/bPersei/. Finder charts with sequence may be created using the AAVSO Variable Star Plotter (https://www.aavso.org/vsp). Observations should be submitted to the AAVSO International Database. See full Alert Notice for more details and information on the targets.

The August 21, 2017 American total solar eclipse through the eyes of GPS

NASA Astrophysics Data System (ADS)

Kundu, Bhaskar; Panda, Dibyashakti; Gahalaut, Vineet K.; Catherine, J. K.

2018-04-01

We explored spatio-temporal variation in Total Electron Contents (TEC) in the ionosphere caused by the recent August 21, 2017 total solar eclipse, which was observed over the United States of America. The path of total solar eclipse passes through the continental parts of the United States of America, starting in the northwestern state of Oregon and ending in the southeastern state of South Carolina, approximately covering 4000 km length. Across this length EarthScope Plate Boundary Observatory (PBO) has been operating a dense cGPS/GNSS networks. During the course of passage of the solar eclipse, the sudden decline in solar radiation by temporarily obscuration by the Moon caused a drop of ˜6-9 × 1016 electrons/m2in the ionosphere with time-delay at the cGPS sites. The significant drop in TEC at cGPS sites captured the average migration velocity of shadow along the eclipse path (0.74 km/s), from which we estimated the Moon's orbital velocity (˜1 km/s). Further, this event also caused some marginal increase in TEC during the eclipse in the Earth's ionosphere in the magnetically conjugate region at the tip of South America and Antarctica, consistent with the model predictions of SAMI3 by Naval Research Laboratory.

Astronomy On-Line Programme Enters "hot Week"

NASA Astrophysics Data System (ADS)

1996-11-01

World's Biggest Astronomy WWW-Event Attracts Thousands of Students The Astronomy On-line Programme (See ESO Press Release 09/96 of 18 June 1996) began officially on 1 October and is now about to enter its most intense phase, known as the Hot Week . On 18 - 22 November, an estimated 4000 astronomy-interested, mostly young people in Europe and on four other continents will get together during five days in what - not unexpected - has become the world's biggest astronomy event ever organised on the World Wide Web. This carefully structured Programme is carried out in collaboration between the European Association for Astronomy Education (EAAE), the European Southern Observatory and the European Commission, under the auspices of the Fourth European Week for Scientific and Technological Culture. The Programme has already had a most visible impact on the school education of natural sciences in various countries; for instance, the Internet-connection of schools has been advanced in some, in order to allow groups to participate. There have been numerous contacts among the groups across the borders and there are clear signs that many Astronomy On-line participants have progressed to use the impressive possibilities of the Web in an efficient and structured way. There has been a lively media interest in Astronomy On-line all over Europe and it is expected to increase during the next week. The current status of Astronomy On-line It is obvious that the pilot function of the Astronomy On-line Programme in the use of the Web has been very effective and that the associated dissemination of astronomical knowledge has been successful. At this time, more than 650 groups have registered with Astronomy On-line. Most come from 31 different European countries and a few dozen groups are located in North and South America as well as in Asia and Australia. Together they have experienced the steady build-up of Astronomy On-line over the past weeks, by means of numerous contributions from a large number of teachers, amateur astronomers and others interested in this field of science. The Astronomy On-line concept is that of a well-structured marketplace with a number of different shops which cater to the participants with a great variety of interesting and educational activities. These range from the availability of useful links to educational and scientific Web sites all around the world, collaborative projects where many participants in different countries work together to achieve an astronomical result and, not the least, the possibility to submit observing programmes to a dozen telescopes at 10 major observatories, including La Silla in Chile. In the early phases of Astronomy On-line , coordinated observations were performed of a lunar eclipse on 27 September and a partial solar eclipse on 12 October. Both events attracted many hundreds of observers from groups in almost all European countries and provisional reports have already been published on the Web. Many beautiful photographs and interesting reports about the activities of the individual groups are also available at their special Web sites.

Effects of the March 2015 solar eclipse on near-surface atmospheric electricity.

PubMed

Bennett, A J

2016-09-28

Measurements of atmospheric electrical and standard meteorological parameters were made at coastal and inland sites in southern England during the 20 March 2015 partial solar eclipse. Clear evidence of a reduction in air temperature resulting from the eclipse was found at both locations, despite one of them being overcast during the entire eclipse. The reduction in temperature was expected to affect the near-surface electric field (potential gradient (PG)) through a reduction in turbulent transfer of space charge. No such effect could be unambiguously confirmed, however, with variability in PG and air-Earth current during the eclipse being comparable to pre- and post-eclipse conditions. The already low solar radiation for this latitude, season and time of day was likely to have contributed to the reduced effect of the eclipse on atmospheric electricity through boundary layer stability. The absence of a reduction in mean PG shortly after time of maximum solar obscuration, as observed during eclipses at lower geomagnetic latitude, implied that there was no significant change in atmospheric ionization from cosmic rays above background variability. This finding was suggested to be due to the relative importance of cosmic rays of solar and galactic origin at geomagnetic mid-latitudes.This article is part of the themed issue 'Atmospheric effects of solar eclipses stimulated by the 2015 UK eclipse'. © 2016 The Author(s).

Coronal jets, which extend from the solar surface to beyond 2 R ⊙, were observed in the polar coronal hole regions during the total solar eclipse on 2017 August 21. In a time-series of white-light images of the corona spanning 70 minutes taken with our multi-site observations of this eclipse, six jets were found as narrow structures upwardly ejected with an apparent speed of about 450 km s‑1 in polar plumes. On the other hand, extreme-ultraviolet (EUV) images taken with the Atmospheric Image Assembly of the Solar Dynamics Observatory show that all of the eclipse jets were preceded by EUV jets. Conversely, all the EUV jets whose brightnesses are comparable to ordinary soft X-ray jets and that occurred in the polar regions near the eclipse period, were observed as eclipse jets. These results suggest that ordinary polar jets generally reach high altitudes and escape from the Sun as part of the solar wind.

The "Eclipse on the Coral Sea" - 13/14 November 2012 (GMT/Australia) - will have happened already. Our intention is to have used this opportunity as a trial run for the eclipse in 2017, which features 1.5 hours of totality across the whole width of the continental US. Conceived first and foremost as an education and public outreach activity, the plan is to engage the public in solar science and technology by providing a way for them to include images they have taken of the solar eclipse, into a movie representation of coronal evolution in time. This project will assimilate as much eclipse photography as possible from the public. The resulting movie(s) will cover all ranges of expertise, and at the basic smartphone or hand-held digital camera level, we expect to have obtained a huge number of images in the case of good weather conditions. The capability of modern digital technology to handle such a data flow is new. The basic purpose of this and the 2017 Megamovie observations is to explore this capability and its ability to engage people from many different communities in the solar science, astronomy, mathematics, and technology. The movie in 2017, especially, may also have important science impact because of the uniqueness of the corona as seen under eclipse conditions. In this presentation we will describe our smartphone application development (see the "Transit of Venus" app for a role model here). We will also summarize data acquisition via both the app and more traditional web interfaces. Although for the Coral Sea eclipse event we don't expect to have a movie product by the time of the AGU, for the 2017 event we do intend to assemble the heterogenous data into beautiful movies within a short space of time after the eclipse. These movies may have relatively low resolution but would extend to the base of the corona. We encourage participation in the 2012 observations, noting that no total eclipse, prior to 2017, will occur in a region with good infrastructure for extended observations. The National Center for Atmospheric Research is sponsored by the National Science Foundation. The Megamovie project is supported by NSF grant AGS-1247226, and JMP's eclipse work about the eclipses of 2012 is supported by NSF grant AGS-1047726.

An area of the solar corona from 1 out to approximately 2.5 solar radii is currently poorly sampled in astronomy. This is largely due to difficulties inherent in observing the sun from space and from the ground. Specifically focusing on ground based observations, the main problem is scattered light in the Earth's atmosphere and in the telescopes themselves. A total solar eclipse solves this problem by blocking the light from the photosphere of the sun before it enters the atmosphere, reducing the scattered light in the atmosphere by a factor of 10,000. However, using a total solar eclipse introduces another challenge due to the small window of time it provides. At any given location in 2017, the totality will last for only about 2.5 minutes and such a small data set limits the studies that can be done on the inner corona. The Citizen Continental-America Telescopic Eclipse Experiment plans to overcome this issue by taking advantage of America's infrastructure and using 60 identical telescopes to collect continuous data of the solar eclipse as the shadow travels from Oregon to South Carolina. By splicing these data together 90 minutes of one-of-a-kind data can be collected, revealing the dynamics of the inner corona as never seen before. For the 2016 Indonesian total solar eclipse the CATE project collected data using 5 sites along the eclipse path. These data were then used to develop processing programs to use on future data. These processes included site-to-site image registration as well as normalized radial graded filtering of the images. Programs were also developed to begin performing studies on the data including overlapping CATE and LASCO space telescope data for a total coronal image as well as thread tracing routines to quantify direction in the coronal filaments. This work was made possible through the National Solar Observatory Research Experiences for Undergraduates (REU) Program, which is funded by the National Science Foundation (NSF). The NSO Training for 2017 Citizen CATE Experiment, funded by NASA (NASA NNX16AB92A), also provided support for this project. The National Solar Observatory is operated by the Association of Universities for Research in Astronomy, Inc. (AURA) under cooperative agreement with the NSF.

The Citizen CATE Experiment: High altitude cirrus cloud removal from eclipse data through use of Kalman filters.

2018-01-01

The Citizen Continental America Telescopic Eclipse (CATE) Experiment was designed to fill in the current data gap for the solar corona from approximately 1 to 2.5 solar radii. Using the total solar eclipse, the project took advantage of the unique opportunity to study this region of the corona from 68 identical sites across the United States. Before the 2017 eclipse, image reduction pipelines and advanced processing techniques were researched and implemented using data that had been collected from the 2016 Indonesian eclipse as a test set. This would speed up the turnaround from data to science after the 2017 eclipse.When processing the 2016 eclipse data, cirrus clouds became apparent moving across the field of view. These would interfere with future processing goals for the data such as coronal filament tracing and polar plume measurements. As the clouds moved across the field they did not completely obscure any part of the image, instead they produced variable, moving absorption across the CATE field of view. This had the effect of creating a noisy signal for each pixel. A noise reduction procedure based on a Kalman filter was developed to effectively remove the clouds from the data. Initial results from the 2016 eclipse data are presented.

The 2016 Total Solar Eclipse provided us an opportunity to introduce astronomy to a much wider audience. The path of totality crossed the Indonesia from Sumatra to the Maluku Islands and ended its journey in the Pacific Ocean. Its path crossed over 4 major islands, 12 provinces and many cities. Most of the cities have minimum exposure to astronomy. langitselatan travelled to observe the eclipse and to do astronomy outreach at the eastern most island under the eclipse path. We chose Maba, a small village in East Halmahera, North Maluku as our site to observe the eclipse as well as conduct a workshop for teachers and students. The aim of the workshop is to introduce astronomy taking advantage of the eclipse as well as raise awareness and curiosity among students. In this paper, we will share a short report regarding the whole trip and event in Maba.

The 2017 total solar eclipse is an unprecedented opportunity for astronomical education throughout the continental United States. With the path of totality passing through 14 states, from Oregon to South Carolina, the United States is expecting visitors from all around the world. Due to the likelihood of clear skies, Idaho was a popular destination for eclipse-chasers. In spite of considerable enthusiasm and interest by the general population, the resources for STEM outreach in the rural Pacific Northwest are very limited. In order to help prepare Idaho for the eclipse, we put together a crowdfunding campaign through the university and raised over $10,000. Donors received eclipse shades as well as information about the eclipse specific to Idaho. Idaho expects 500,000 visitors, which could present a problem for the many small, rural towns scattered across the path of totality. In order to help prepare and equip the public for the solar eclipse, we conducted a series of site visits to towns in and near the path of totality throughout Idaho. To maximize the impact of this effort, the program included several partnerships with local educational and community organizations and a focus on the sizable refugee and low-income populations in Idaho, with considerable attendance at most events.

Public Education Plans for the 2017 August 21 Total Solar Eclipse

A total solar eclipse will cross the continental United States on 2017 August 21, the first such in 99 years and the first whose path of totality on land is entirely in the United States since 1776. People in the rest of the United States-as well as in Canada, Central America, and northern South America-will have a partial solar eclipse. Totality will range up to about 70 km in diameter, and will be visible from a path that extends from Oregon to South Carolina. Cloudiness statistics based on decades on satellite infrared imaging are more favorable for western sites. The sun's diameter will be 80% covered in Miami (south of totality) and New York (north of totality), and 70% covered in Los Angeles (south of totality). For the Working Group on Solar Eclipses of the International Astronomical Union, I maintain a website at http://eclipses.info that provides links to a wide variety of eclipse-related material and to useful websites run by others.Prior to this total eclipse, annular eclipses will cross Africa (from Gabon to Tanzania and Madagascar) and Isle de la Réunion on 2016 September 1, and Chile and Argentina on 2017 February 26, at which time we plan an eclipse workshop in Esquel, Argentina.For the forthcoming 2017 eclipse, we acknowledge grants to JMP and Williams College from the Solar Terrestrial Program of the Atmospheric and Geospace Sciences Division of the National Science Foundation and from the Committee for Research and Exploration of the National Geographic Society.

Statistical analysis of geomagnetic field variations during solar eclipses

2018-04-01

We investigate the geomagnetic field variations recorded by INTERMAGNET geomagnetic observatories, which are observed while the Moon's umbra or penumbra passed over them during a solar eclipse event. Though it is generally considered that the geomagnetic field can be modulated during solar eclipses, the effect of the solar eclipse on the observed geomagnetic field has proved subtle to be detected. Instead of exploring the geomagnetic field as a case study, we analyze 207 geomagnetic manifestations acquired by 100 geomagnetic observatories during 39 solar eclipses occurring from 1991 to 2016. As a result of examining a pattern of the geomagnetic field variation on average, we confirm that the effect can be seen over an interval of 180 min centered at the time of maximum eclipse on a site of a geomagnetic observatory. That is, demonstrate an increase in the Y component of the geomagnetic field and decreases in the X component and the total strength of the geomagnetic field. We also find that the effect can be overwhelmed, depending more sensitively on the level of daily geomagnetic events than on the level of solar activity and/or the phase of solar cycle. We have demonstrated it by dividing the whole data set into subsets based on parameters of the geomagnetic field, solar activity, and solar eclipses. It is suggested, therefore, that an evidence of the solar eclipse effect can be revealed even at the solar maximum, as long as the day of the solar eclipse is magnetically quiet.

Absolute Properties of the Eclipsing Binary Star BF Draconis

Lacy, Claud H. Sandberg; Torres, Guillermo; Fekel, Francis C.; Sabby, Jeffrey A.; Claret, Antonio

2012-06-01

BF Dra is now known to be an eccentric double-lined F6+F6 binary star with relatively deep (0.7 mag) partial eclipses. Previous studies of the system are improved with 7494 differential photometric observations from the URSA WebScope and 9700 from the NFO WebScope, 106 high-resolution spectroscopic observations from the Tennessee State University 2 m automatic spectroscopic telescope and the 1 m coudé-feed spectrometer at Kitt Peak National Observatory, and 31 accurate radial velocities from the CfA. Very accurate (better than 0.6%) masses and radii are determined from analysis of the two new light curves and four radial velocity curves. Theoretical models match the absolute properties of the stars at an age of about 2.72 Gyr and [Fe/H] = -0.17, and tidal theory correctly confirms that the orbit should still be eccentric. Our observations of BF Dra constrain the convective core overshooting parameter to be larger than about 0.13 Hp . We find, however, that standard tidal theory is unable to match the observed slow rotation rates of the components' surface layers.

2017-11-01

Atmospheric surface boundary layer measurements of wind and thermodynamic parameters are conducted during variable insolation conditions, including the 2017 eclipse, using an unmanned aircraft system. It is well known that the air temperatures can drop significantly during a total solar eclipse as has been previously observed. In past eclipses, these observations have primarily been made on the ground. We present results from airborne measurements of the near surface boundary layer using a small unmanned aircraft with high temporal resolution wind and thermodynamic observations. Questions that motivate the study include: How does the temperature within the lower atmospheric boundary vary during an eclipse? What impact does the immediate removal of radiative heating on the ground have on the lower ABL? Do local wind patterns change during an eclipse event and if so why? Will there be a manifestation of the nocturnal boundary layer wind maximum? Comparisons are made with the DOE ARM SGP site that experiences a lower but still significant insolation.

The solar eclipse of 21 August 2017 will be visible to over a half billion people across the entire North American continent. The roughly 100-mile wide path of totality, stretching from Oregon to South Carolina, will be the destination for tens of millions of people. In the decades since 1979, when the last total solar eclipse was visible from the continental USA, the phenomenon of Internet enabled citizen science has grown to be an accepted mode for science. The Citizen Continental-America Telescopic Eclipse (Citizen CATE) experiment has been funded as one of the three 2017 eclipse related NASA STEM agreements to engage citizen scientists in a unique, cutting-edge solar physics experiment. Teams across the USA will be trained to use standardized refracting telescope and digital imager set-ups to observe the solar corona during the eclipse, acquiring multiple exposures to create one high dynamic range image. After observing during the eclipse, the CATE volunteers will upload the combined image to a cloud-storage site and the CATE team will then work to properly orient and align all the images collected from across the continent to produce a continuous 90-minutes movie. A time-compressed first cut of the entire sequence will be made available to media outlets on the same afternoon of the eclipse, with hope that high quality images will encourage the most accurate coverage of this Great American Eclipse. We discuss overall the project, as well as details of the initial tests of the prototype set-up (including in the Faroe Islands during the March 2015 total solar eclipse) and plans for the future night-time and day-time observing campaigns, and for a handful of observing teams positioned for overlapping observations of the March 2016 total solar eclipse in the South Pacific.

We report observation and an early analysis of stellar background from total solar eclipse in Ternate, Indonesia. The eclipse phenomena which occurred on March, 9th 2016 was observed with certain portable instruments in order to obtain the stars behind the Sun in particular field of view and resolution. From our observation site in Ternate city, solar eclipse occurred in the late morning when the weather was unfortunately cloudy. However, during the darkness of totality, we obtained several point source objects between the gaps of the moving clouds and we suspected them as very faint stars due to their appearance in several frames. Those so called stars have been identified and measured with respect to their positions toward the center of the Sun. The main purpose of this research is to revisit strong lensing calculation of the Sun during total solar eclipse by measuring the deflection angle of the background stars as it had been calculated by Einstein and proved by Eddington at a total solar eclipse in 1919. To accomplish this aim, we need to conduct another observation to measure position of the same stars in the next period when those stars appear in the night sky.

Atmospheric Responses from Radiosonde Observations of the 2017 Total Solar Eclipse

NASA Astrophysics Data System (ADS)

Fowler, J.

2017-12-01

The Atmospheric Responses from Radiosonde Observations project during the August 21st, 2017 Total Solar Eclipse was to observe the atmospheric response under the shadow of the Moon using both research and operational earth science instruments run primarily by undergraduate students not formally trained in atmospheric science. During the eclipse, approximately 15 teams across the path of totality launched radiosonde balloon platforms in very rapid, serial sonde deployment. Our strategy was to combine a dense ground observation network with multiple radiosonde sites, located within and along the margins of the path of totality. This can demonstrate how dense observation networks leveraged among various programs can "fill the gaps" in data sparse regions allowing research ideas and questions that previously could not be approached with courser resolution data and improving the scientific understanding and prediction of geophysical and hazardous phenomenon. The core scientific objectives are (1) to make high-resolution surface and upper air observations in several sites along the eclipse path (2) to quantitatively study atmospheric responses to the rapid disappearance of the Sun across the United States, and (3) to assess the performance of high-resolution weather forecasting models in simulating the observed response. Such a scientific campaign, especially unique during a total solar eclipse, provides a rare but life-altering opportunity to attract and enable next-generation of observational scientists. It was an ideal "laboratory" for graduate, undergraduate, citizen scientists and k-12 students and staff to learn, explore and research in STEM.

We report on high-contrast data reduction of white-light images from the August 21, 2017, total solar eclipse. We show the configuration of the solar corona at this declining phase of the solar-activity cycle, with the projection onto the plane of the sky of the three-dimensional coronal streamers plus extensive polar plumes. We discuss the relation of the white-light coronal loops visible in our observations with extreme-ultraviolet observations from NASA’s Solar Dynamics Observatory Atmospheric Imaging Assembly (AIA) and NOAA’s GOES-16 Solar Ultraviolet Imager (SUVI). We show differences and motions over a 65-minute interval between observations from our main site at Willamette University in Salem, Oregon, and a subsidiary site in Carbondale, Illinois. We discuss, in particular, a giant demarcation about 1 solar radius outward in the southwest that crosses the radial streamers.Our observations of the eclipse were sponsored in large part by the Committee for Research and Exploration of the National Geographic Society and by the Solar Terrestrial Program of the National Geographic Society. Additional support was received from the NASA Massachusetts Space Grant Consortium, the Sigma Xi honorary scientific society, the University of Pennsylvania (for DS), the Slovak Academy of Sciences VEGA project 2/0003/16, and the Freeman Foote Expeditionary and Brandi funds at Williams College.

We report the results of photometric observations for doubly eclipsing binaries OGLE-LMC-ECL-15674 and OGLE-LMC-ECL-22159, both of which are composed of two pairs (designated A&B) of a detached eclipsing binary located in the Large Magellanic Cloud. The light curves were obtained by high-cadence time-series photometry using the Korea Microlensing Telescope Network 1.6 m telescopes located at three southern sites (CTIO, SAAO, and SSO) between 2016 September and 2017 January. The orbital periods were determined to be 1.433 and 1.387 days for components A and B of OGLE-LMC-ECL-15674, respectively, and 2.988 and 3.408 days for OGLE-LMC-ECL-22159A and B, respectively. Our light curve solutions indicate that the significant changes in the eclipse depths of OGLE-LMC-ECL-15674A and B were caused by variations in their inclination angles. The eclipse timing diagrams of the A and B components of OGLE-LMC-ECL-15674 and OGLE-LMC-ECL-22159 were analyzed using 28, 44, 28, and 26 new times of minimum light, respectively. The apsidal motion period of OGLE-LMC-ECL-15674B was estimated by detailed analysis of eclipse timings for the first time. The detached eclipsing binary OGLE-LMC-ECL-15674B shows a fast apsidal period of 21.5 ± 0.1 years.

Visualization and Quality Control Web Tools for CERES Products

The CERES project continues to provide the scientific community a wide variety of satellite-derived data products such as observed TOA broadband shortwave and longwave observed fluxes, computed TOA and Surface fluxes, as well as cloud, aerosol, and other atmospheric parameters. They encompass a wide range of temporal and spatial resolutions, suited to specific applications. Now in its 16-year, CERES products are mostly used by climate modeling communities that focus on global mean energetics, meridianal heat transport, and climate trend studies. In order to serve all our users, we developed a web-based Ordering and Visualization Tool (OVT). Using Opens Source Software such as Eclipse, java, javascript, OpenLayer, Flot, Google Maps, python, and others, the OVT Team developed a series of specialized functions to be used in the process of CERES Data Quality Control (QC). We mention 1- and 2-D histogram, anomaly, deseasonalization, temporal and spatial averaging, side-by-side parameter comparison, and others that made the process of QC far easier and faster, but more importantly far more portable. We are now in the process of integrating ground site observed surface fluxes to further facilitate the CERES project to QC the CERES computed surface fluxes. These features will give users the opportunity to perform their own comparisons of the CERES computed surface fluxes and observed ground site fluxes. An overview of the CERES OVT basic functions using Open Source Software, as well as future steps in expanding its capabilities will be presented at the meeting.

On the Totality of the Eclipse in AD 628 in the Nihongi

NASA Astrophysics Data System (ADS)

Tanikawa, Kiyotaka; Sôma, Mitsuru

2004-02-01

It is widely accepted that the solar eclipse on AD 628 April 10 (the reign of Empress Suiko, 36th year, 3rd month, 2nd day) recorded in the Nihongi (****) was not total, but partial at the site of observation, though it is written as an exhausted eclipse. A contemporary Japanese occultation observation on AD 681 November 3 is also suspected as being a missing of Mars in the glaring light of the Moon. We suggest in this paper that both records in the Nihongi may be true. Several reasonings are put forward. We then point out the possibility that the value of ΔT at around AD 600 is about 2000s which is far less than 4500s, the value adopted by Stephenson (1997, Historical Eclipses and Earth's Rotation). Lunar grazing occultation data are found to be very useful.

1998-09-01

The last total solar eclipse of the millenium will be observed from Turkey which bridges two components and has been the cradle of so many past civilisations. Wouldn't you like to witness this magnificient event in the mystic ambiance of central Anatolia which offers its guests Turkish hospitality and a lot of hystorical examples of paganism, Christianity and Islam. Among the countries from which the eclipse will be visible , Turkey seems to be one of the most suitable countries in terms of its climate and observational facilities. Kandilli Observatory and the Earthquake Research Institute has arranged field work on the eclipse path to determine the suitable points for the observations.

The Assembled Solar Eclipse Package (ASEP) is not only an integrated apparatus constructed to obtain imaging data during solar eclipse, but also it involved sky brightness and live streaming requirement. Main four parts of ASEP are composed by two imaging data recorders, one high definition video streaming camera, and a sky quality meter instrument (SQM) linked by a personal computer and motorized mounting. The parts are common instruments which are used for education or personal use. The first part is used to capture corona and prominence image during totality. For the second part, video is powerful data in order to educate public through web streaming lively. The last part, SQM is used to confirm our imaging data during obscuration. The perfect prominence picture was obtained by one of the data capture using William-Optics F=388mm with Nikon DSLR D3100. In addition, the diamond ring and corona were recorded by the second imaging tool using Sky Watcher F=910mm with Canon DSLR 60D. The third instrument is the Sony HXR MC5 streaming set to be able to broadcast to public domain area via official website. From the SQM, the value of the darkness during totality is quiet similar as a dawn condition. Finally, ASEP was entirely successful and be able to fulfil our competency as educational researcher in university.

For the August 2017 eclipse, NASA's Marshall Space Flight Center partnered with the U.S. Space and Rocket Center (USSRC), Austin Peay State University (APSU) in Clarksville, Tennessee, the University of Alabama in Huntsville (UAH), the Interactive NASA Space Physics Ionosphere Radio Experiments (INSPIRE) Project, and the local school systems of Montgomery County, Tennessee, and Christian County, Kentucky. Multiple site visits and workshops were carried out during the first eight months of 2017 to prepare local teachers and students for the eclipse. A special curriculum was developed to prepare USSRC Space Camp and INSPIRE students to observe and participate in science measurements during the eclipse. Representatives from Christian County school system and APSU carried out observations for the Citizen Continental-America Telescopic Eclipse (CATE) Experiment in two separate locations. UAH and APSU as part of the Montana State Ballooning Project, launched balloons containing video cameras and other instruments. USSRC Space Camp students and counselors and INSPIRE students conducted science experiments that included the following: atmospheric science investigations of the atmospheric boundary layer, very-low frequency and Ham radio observations to investigate ionospheric responses to the eclipse, animal and insect observations, solar-coronal observations, eclipse shadow bands. We report on the results of all these investigations.

The D-Region Ionospheric Response to the 2017 Solar Eclipse

2017-12-01

VLF/LF radio remote sensing (0.5-500 kHz) is an effective means for quantifying the D-region ionosphere (60-90 km altitude). Disturbances in the ionospheric electron density induce changes in the propagation of VLF/LF signals, so a network of transmitters and receivers can effectively "image" a disturbed region. VLF/LF signals can all be detected from 100s-1000s of km away. We utilize Georgia Tech's network of highly-sensitive VLF/LF receivers to quantify the lower ionospheric response to the "Great American Eclipse". Nine of these were deployed and operational across the Continental US, Alaska and Puerto Rico all operated successfully. Each receiver synchronously recorded the full radio spectrum between 0.5-470 kHz. The included figure shows the eclipse track at 80 km altitude with a green swath. The nine operational receivers are shown with blue stars, and operational VLF/LF transmitters in dark red. Gray lines are shown for each great-circle path linking a VLF/LF transmitter to a receiver. This constellation forms a dense spider's-web grid of radio links, with which we can effectively image the disturbed patch of the D-region ionosphere as it moves across the country. In addition, shown in yellow are NDGPS transmitters which lie between 285-325 kHz. The red dots are the 230,000 geolocated lightning strokes during the 90-mintue eclipse pass, each of which emitted an intense VLF/LF impulse. These are also detected by our receivers. We present our observations and comparison with a theoretical model, using a combination of three techniques established by a series of three 2017 journal papers: (1) Polarization measurements of VLF/LF transmitter signals, (2) Lightning-generated VLF sferics detected 1000s of km away, and (3) NDGPS beacons near 300 kHz for shorter-range sounding of a small patch of the ionosphere. We find evidence of large scale ionospheric changes which affect the D-region over the entire continental region with a slowly-varying signal perturbation. At some sites close to the totality zone, however, we have evidence of forward scattering from the shadow of the moon, which effectively is a patch of nighttime surrounded by daytime, that can only be observed in a narrower region around the totality zone. Implications of these results for D-region ionospheric dynamics are discussed.

Camera characterization for all-sky polarization measurements during the 2017 solar eclipse

A solar eclipse provides a rare opportunity to observe skylight polarization during conditions that are fundamentally different than what we see every day. On 21 August 2017 we will measure the skylight polarization during a total solar eclipse in Rexburg, Idaho, USA. Previous research has shown that during totality the sky polarization pattern is altered significantly to become nominally symmetric about the zenith. However, there are still questions remaining about the details of how surface reflectance near the eclipse observation site and optical properties of aerosols in the atmosphere influence the totality sky polarization pattern. We will study how skylight polarization in a solar eclipse changes through each phase and how surface and atmospheric features affect the measured polarization signatures. To accomplish this, fully characterizing the cameras and fisheye lenses is critical. This paper reports measurements that include finding the camera sensitivity and its relationship to the required short exposure times, measuring the camera's spectral response function, mapping the angles of each camera pixel with the fisheye lens, and taking test measurements during daytime and twilight conditions. The daytime polarimetric images were compared to images from an existing all-sky polarization imager and a polarimetric radiative transfer model.

Spirit Movie of Phobos Eclipse, Sol 675

[figure removed for brevity, see original site] Spirit Phobos Eclipse Animation

NASA's Mars Exploration Rover Spirit observed the Martian moon Phobos entering the shadow of Mars during the night of the rover's 675th sol (Nov. 27, 2005). The panoramic camera captured 16 images, spaced 10 seconds apart, covering the period from when Phobos was in full sunlight to when it was entirely in shadow. As with our own Moon during lunar eclipses on Earth, even when in the planet's shadow, Phobos was not entirely dark. The small amount of light still visible from Phobos is a kind of 'Mars-shine' -- sunlight reflected through Mars' atmosphere and into the shadowed region.

This clip is a sequence of the 16 images showing the eclipse at about 10 times normal speed. It shows the movement of Phobos from left to right as the moon enters the shadow. Scientists are using information about the precise timing of Martian moon eclipses gained from observations such as these to refine calculations about the orbital path of Phobos. The precise position of Phobos will be important to any future spacecraft taking detailed pictures of the moon or landing on its surface.

Visualization and Quality Control Web Tools for CERES Products

The NASA CERES project continues to provide the scientific communities a wide variety of satellite-derived data products such as observed TOA broadband shortwave and longwave observed fluxes, computed TOA and Surface fluxes, as well as cloud, aerosol, and other atmospheric parameters. They encompass a wide range of temporal and spatial resolutions, suited to specific applications. CERES data is used mostly by climate modeling communities but also by a wide variety of educational institutions. To better serve our users, a web-based Ordering and Visualization Tool (OVT) was developed by using Opens Source Software such as Eclipse, java, javascript, OpenLayer, Flot, Google Maps, python, and others. Due to increased demand by our own scientists, we also implemented a series of specialized functions to be used in the process of CERES Data Quality Control (QC) such as 1- and 2-D histograms, anomalies and differences, temporal and spatial averaging, side-by-side parameter comparison, and others that made the process of QC far easier and faster, but more importantly far more portable. With the integration of ground site observed surface fluxes we further facilitate the CERES project to QC the CERES computed surface fluxes. An overview of the CERES OVT basic functions using Open Source Software, as well as future steps in expanding its capabilities will be presented at the meeting.

The Guilford-Carleton Eclipse Expedition of 1900

English, Thomas R., III

2006-12-01

The solar eclipse of 1900 May 28 provided an opportunity for American astronomers to make observations from home soil, as the shadow tracked across the southeastern United States from New Orleans to Norfolk. Eclipse parties were scattered throughout the southern states, including large-scale scientific teams traveling to sites in Georgia and North Carolina. These major operations, staffed by groups from Yerkes, Princeton, USNO, and Lick, featured multiple observing programs and all the modern techniques they could manage. In addition to the major astrophysical endeavors, there were many smaller parties in the field in 1900 that resembled the more casual eclipse expeditions that were characteristic of a few decades before. In these efforts, relatively small groups of observers used modest instruments and made mostly visual observations, and the expedition was as much a social event as it was a scientific venture. One such group was the party from Carleton College and Guilford College that observed from a fruit farm in Southern Pines, NC. At the turn of the century, the Goodsell Observatory at Carleton College in Minnesota was an important regional astronomical facility that had provided weather and time data for over 20 years, and was the site of publication of Popular Astronomy, a widely circulated astronomical journal. At Guilford College, on the other hand, the astronomy course was taught by the school’s Treasurer, and there were no significant astronomical facilities. The presentation will explain how these two schools came to combine efforts to study the 1900 solar eclipse, and will summarize the events of the trip and the observations made. This research was supported in part by the Herbert C. Pollock Award of the Dudley Observatory.

What If It Rains on Your Eclipse? Planning Ahead for August 2017

It was a dark and rainy morning, not far out of Shanghai, when we saw the 2009 July 22 total solar eclipse. Many of the Americans puttering around their equipment that morning, in hopes that the sky would clear enough to catch some of event they had traveled around the world to view, were already planning ahead for 2017 August 21, when a narrow strip of the United States will experience up to 2 minutes and 45 seconds of totality. For most people, a total solar eclipse is once in a lifetime event steeped in legend. If you are situated along this privileged corridor, you will have a wonderful opportunity for public outreach. But what if it rains? Historically, August is mostly sunny at the location of greatest eclipse, near Makanda, Illinois. Even with such favorable circumstances, having a rain plan will ensure you make the most of the occasion. First, the flexibility to relocate your program to take advantage of the most favorable weather would be ideal. If that is not a realistic option, include some protective gear with your equipment so that you can set up despite misty or drizzling conditions. Second, monitoring changing light levels and temperatures should be possible even under cloudy skies. Third, for some sites, changes in wildlife behavior may also be noticeable. If the weather is clear, such projects could enhance your program during the partial phases of the eclipse and provide enrichment materials for those unable to attend. While 2017 may still seem in the distant future to all but eclipse fanatics, some creativity and advance brainstorming will ensure that your outreach program shines during the event, even if the Sun does not cooperate.

2015-01-01

We observe the long period (5.6 years) Eclipsing Binary Variable Star EE Cep during it's 2014 eclipse. It was observed on every clear night from the Maria Mitchell Observatory as well as remote sites for a total of 25 nights. Each night consisted of a detailed time series in BVRI looking for short term variations for a total of >9000 observations. The data was transformed to the Standard System. In addition, a time series was captured during the night of the eclipse. This data provides an alternate method to determine Time of Minimum than traditionally performed. The TOM varied with color. Several strong correlations are seen between colors substantiating the detection of variations on a time scale of hours. The long term light curve shows 5 interesting and different Phases with different characteristics.

The authors discusse the insuccess of the observation of the Total Eclipse of the Moon from 10 december 2011 in Romania and relate them with meteoconditions. Only a very short part of the last penumbral phase was observed, while the inital part and the totality was not observed due to very dense clouds. The change in color and brightness during this phase was signaled. Meanwhile, there is an area of science where clouds are of great use and interest. This area is Atmospheric optics, while the science which study clouds is meteorology. Clouds in combination with Solar and Moon light could give rise to a variety of strange, rare and unobvious phenomena in the atmosphere (sky), sometimes confused with Unidentified Flying Objects (UFO). The importance of meteorology for astronomy and atmospheric optics is underlined and an invitation to astronomers to use unfavourable days for athmospheric observations was sent. The web address of the site by Les Cowley, designed for atmospheric optics phenomena is contained in the text of the entry.

Ionospheric Bow Waves and Perturbations Induced by the 21 August 2017 Solar Eclipse

During solar eclipses, the Moon's shadow causes a large reduction in atmospheric energy input, including not only the stratosphere but also the thermosphere and ionosphere. The eclipse shadow has a supersonic motion which is theoretically expected to generate atmospheric bow waves, similar to a fast-moving river boat, with waves starting in the lower atmosphere and propagating into the ionosphere. However, previous geographically limited observations have had difficulty detecting these weak waves within the natural background atmospheric variability, and the existence of eclipse-induced ionospheric waves and their evolution in a complex coupling system remain controversial. During the 21 August 2017 eclipse, high fidelity and wide coverage ionospheric observations provided for the first time an oversampled set of eclipse data, using a dense network of Global Navigation Satellite System receivers at ˜2,000 sites in North America. We show the first unambiguous evidence of ionospheric bow waves as electron content disturbances over central/eastern United States, with ˜1 h duration, 300-400 km wavelength and 280 m/s phase speed emanating from and tailing the totality region. We also identify large ionospheric perturbations moving at the supersonic speed of the maximum solar obscuration which are too fast to be associated with known gravity wave or large-scale traveling ionospheric disturbance processes. This study reveals complex interconnections between the Sun, Moon, and Earth's neutral atmosphere and ionosphere and demonstrates persistent coupling processes between different components of the Earth's atmosphere, a topic of significant community interest.

22 July 2009 total solar eclipse induced gravity waves in ionosphere as inferred from GPS observations over EIA

Kumar, K. Vijay; Maurya, Ajeet K.; Kumar, Sanjay; Singh, Rajesh

2016-11-01

In the present contribution we investigate the variation in the Global Positioning System (GPS) derived ionospheric Total Electron Content (TEC) over Equatorial Ionization Anomaly (EIA) region on the rare occasional astronomical phenomenon of total solar eclipse of 22 July 2009. The aim is to study and identify the wave like structure enumerated due to solar eclipse induced gravity waves in the F-region ionosphere altitude. The work is aimed to understand features of horizontal and vertical variation of atmospheric gravity waves (AGWs) properties over the Equatorial Ionization Anomaly (EIA) region in Indian low latitude region. The ionospheric observations is from the site of Allahabad (lat 25.4° N; lon. 81.9° E; dip 38.6° N) located at the fringe of eclipse totality path. The estimated vertical electron density profile from FORMOSAT-3/COSMIC GPS-RO satellite, considering all the satellite line of sight around the time of eclipse totality shows maximum depletion of 43%. The fast fourier transform and wavelet transform of GPS DTEC data from Allahabad station (Allahabad: lat 25.4 N; lon. 81.9 E) shows the presence of periodic waves of ∼20 to 45 min and ∼70 to 90 min period at F-region altitude. The shorter period correspond to the sunrise time morning terminator and longer period can be associated with solar eclipse generated AGWs. The most important result obtained is that our results along with previous result for wave like signatures in D-region ionosphere from Allahabad station show that AGWs generated by sunrise time terminator have similarity in the D and F region of the ionosphere but solar eclipse induced AGWs show higher period in the F-region compared to D-region ionosphere.

How Cool was the Eclipse? Atmospheric Measurements and Citizen Science via NASA's GLOBE Observer

2017-12-01

The solar eclipse of 2017 presented an extraordinary opportunity to engage the public in shared science activity across the entire United States. While a natural focus of the eclipse was on astronomy and heliophysics, there was also an opening for excellent connections to Earth science. Because of the excitement of the event, many people gathered for long periods before and after totality, a perfect opportunity for observations and data collection to explore the impact of the eclipse on the atmosphere. The data was collected via NASA's GLOBE Observer app, a subset of the Global Learning and Observations to Benefit the Environment Program, a citizen science project which has been active for more than 20 years training teachers to collect many different types of environmental science data with their students. GLOBE Observer expands that audience to citizen scientists who might not be connected to a school, but are still interested in collecting data. In addition to the clouds observations that are normally part of GLOBE Observer, a special temporary protocol was added for the eclipse to include air temperature. Both types of measurements were collected at regular intervals for several hours before and after the point of maximum eclipse. By crowdsourcing data from all across the United States, on and off the path of totality, the hope was to be able to see patterns that wouldn't be apparent with fewer data points. In particular, there are few sources of detailed cloud data from the ground, including cloud type as well as overall cloud cover, especially as collected during a unique natural experiment such as an eclipse. This presentation will report preliminary results of the GLOBE Observer eclipse citizen science project, including participation totals and impact, data site distribution, as well as early analyses of both temperature and cloud data.

The white-light corona (WLC) during the total solar eclipse of 2009 July 22 was observed by several teams in the Moon's shadow stretching from India and China across the Pacific Ocean with its many isolated islands. We present a comparison of the WLC as observed by eclipse teams located in China (Shanghai region) and on the Enewetak Atoll in the Marshall Islands, with observations taken 112 minutes apart, combined with near-simultaneous space observations. The eclipse was observed at the beginning of solar cycle 24, during a deep solar minimum (officially estimated as 2008 December according to the smoothed sunspot number, but very extended). The solar corona shows several different types of features (coronal holes, polar rays, helmet streamers, faint loops, voids, etc.), though it was extremely sparse in streamers as shown from Large-Angle Spectroscopic Coronagraph data. No large-scale dynamical phenomena were seen when comparing the observations from the two sites, confirming that the corona was quiescent. We measure a Ludendorff flattening coefficient of 0.238, typical of solar minimum.

In 1994-1996 the Sun and the Earth passed through the equatorial plane of Saturn and therefore through the orbital planes of its main satellites. During this period, phenomena involving seven of these satellites were observed. Light curves of eclipses by Saturn and of mutual eclipses and occultations were recorded by the observers of the international campaign PHESAT95 organized by the Institut de mécanique céleste, Paris, France. Herein, we report 66 observations of 43 mutual events from 16 sites. For each observation, information is given about the telescope, the receptor, the site and the observational conditions. This paper gathers together all these data and gives a first estimate of the precision providing accurate astrometric data useful for the development of dynamical models.

Digitizing Villanova University's Eclipsing Binary Card Catalogue

2018-01-01

Villanova University’s Department of Astrophysics and Planetary Science has years of hand-written archival data on Eclipsing Binaries at its disposal. This card catalog began at Princeton in the 1930’s with notable contributions from scientists such as Henry Norris Russel. During World War II, the archive was moved to the University of Pennsylvania, which was one of the world centers for Eclipsing Binary research, consequently, the contributions to the catalog during this time were immense. It was then moved to University of Florida at Gainesville before being accepted by Villanova in the 1990’s. The catalog has been kept in storage since then. The objective of this project is to digitize this archive and create a fully functional online catalog that contains the information available on the cards, along with the scan of the actual cards. Our group has built a database using a python-powered infrastructure to contain the collected data. The team also built a prototype web-based searchable interface as a front-end to the catalog. Following the data-entry process, information like the Right Ascension and Declination will be run against SIMBAD and any differences between values will be noted as part of the catalog. Information published online from the card catalog and even discrepancies in information for a star, could be a catalyst for new studies on these Eclipsing Binaries. Once completed, the database-driven interface will be made available to astronomers worldwide. The group will also acquire, from the database, a list of referenced articles that have yet to be found online in order to further pursue their digitization. This list will be comprised of references in the cards that were neither found on ADS nor online during the data-entry process. Pursuing the integration of these references to online queries such as ADS will be an ongoing process that will contribute and further facilitate studies on Eclipsing Binaries.

Determining the source at the Sun of the slow solar wind is one of the major unsolved problems in solar and heliospheric physics. First, we review the existing theories for the slow wind and argue that they have difficulty accounting for both the observed composition of the wind and its large angular extent. A new theory in which the slow wind originates from the continuous opening and closing of narrow open field corridors, the S-Web model, is described. Support for the S-Web model is derived from MHD solutions for the quasisteady corona and wind during the time of the August 1, 2008 eclipse. Additionally, we perform fully dynamic numerical simulations of the corona and heliosphere in order to test the S-Web model as well as the interchange model proposed by Fisk and co-workers. We discuss the implications of our simulations for the competing theories and for understanding the corona - heliosphere connection, in general.

Crowdsourcing a Spatial Temporal Study of Low Frequency (LF) Propagation Effects Due to a Total Solar Eclipse: Engaging Students and Citizens in STEM

2015-12-01

The first experiments to study the effects of a solar eclipse on radio wave propagation were done in 1912 utilizing Low Frequency (LF; 30 - 300 kHz) radio waves at a handful of sites across Europe before any theory of the ionosphere had been confirmed and even before the word "ionosphere" existed. In the 1920s, a large cooperative experiment was promoted in the U.S. by Scientific American magazine. They collected over 2000 reports of AM broadcast stations from throughout the U.S. Unfortunately, many of the submissions were unusable because they lacked critical information such as date, time or location. We propose to use the 2017 solar eclipse over the continental U.S. to conduct the first wide-area LF propagation study. To perform this study, we plan to crowdsource the collection of the data by engaging student groups, citizens, and the scientific community. The tools for the different collection stations will consist of a simple homemade antenna, a simple receiver to convert the radio frequency (RF) signals to audio frequencies and a smart phone app. By using the time, date and location features of the smart phone, the problems experienced in the Scientific American experiment will be minimized. By crowdsourcing the observation sites, a number of different short, medium and long-paths studies can be obtained as the total eclipse crosses the continental U.S. The transmitter for this experiment will be WWVB located near Fort Collins, Colorado on 60.000 kHz. This is a U.S. frequency standard that is operated by NIST and transmits time codes. A second frequency, 55.500 kHz transmitted by a LF station in Dixon, CA is also being considered for this experiment. We will present an overall strategy for recruiting participants/crowdsourcing the RF collections during the 2017 total solar eclipse. Preliminary coverage calculations will be presented for WWVB and Dixon, as well as path loss calculations that can be expected during the solar eclipse condition. We will also present the 2016 plan to pilot/refine the design of the RF collection system (e.g., antenna, app) with multiple teams to help ensure project success during the eclipse. Also, we wish to solicit input from AGU attendees on how to increase participation and improve the experiment. Lastly, we will announce social media, website, and standards-based curriculum resources.

SAFOD Brittle Microstructure and Mechanics Knowledge Base (SAFOD BM2KB)

Babaie, H. A.; Hadizadeh, J.; di Toro, G.; Mair, K.; Kumar, A.

2008-12-01

We have developed a knowledge base to store and present the data collected by a group of investigators studying the microstructures and mechanics of brittle faulting using core samples from the SAFOD (San Andreas Fault Observatory at Depth) project. The investigations are carried out with a variety of analytical and experimental methods primarily to better understand the physics of strain localization in fault gouge. The knowledge base instantiates an specially-designed brittle rock deformation ontology developed at Georgia State University. The inference rules embedded in the semantic web languages, such as OWL, RDF, and RDFS, which are used in our ontology, allow the Pellet reasoner used in this application to derive additional truths about the ontology and knowledge of this domain. Access to the knowledge base is via a public website, which is designed to provide the knowledge acquired by all the investigators involved in the project. The stored data will be products of studies such as: experiments (e.g., high-velocity friction experiment), analyses (e.g., microstructural, chemical, mass transfer, mineralogical, surface, image, texture), microscopy (optical, HRSEM, FESEM, HRTEM]), tomography, porosity measurement, microprobe, and cathodoluminesence. Data about laboratories, experimental conditions, methods, assumptions, equipments, and mechanical properties and lithology of the studied samples will also be presented on the website per investigation. The ontology was modeled applying the UML (Unified Modeling Language) in Rational Rose, and implemented in OWL-DL (Ontology Web Language) using the Protégé ontology editor. The UML model was converted to OWL-DL by first mapping it to Ecore (.ecore) and Generator model (.genmodel) with the help of the EMF (Eclipse Modeling Framework) plugin in Eclipse. The Ecore model was then mapped to a .uml file, which later was converted into an .owl file and subsequently imported into the Protégé ontology editing environment. The web-interface was developed in java using eclipse as the IDE. The web interfaces to query and submit data were implemented applying JSP, servlets, javascript, and AJAX. The Jena API, a Java framework for building Semantic Web applications, was used to develop the web-interface. Jena provided a programmatic environment for RDF, RDFS, OWL, and SPARQL query engine. Building web applications with AJAX helps retrieving data from the server asynchronously in the background without interfering with the display and behavior of the existing page. The application was deployed on an apache tomcat server at GSU. The SAFOD BM2KB website provides user-friendly search, submit, feedback, and other services. The General Search option allows users to search the knowledge base by selecting the classes (e.g., Experiment, Surface Analysis), their respective attributes (e.g., apparatus, date performed), and the relationships to other classes (e.g., Sample, Laboratory). The Search by Sample option allows users to search the knowledge base based on sample number. The Search by Investigator lets users to search the knowledge base by choosing an investigator who is involved in this project. The website also allows users to submit new data. The Submit Data option opens a page where users can submit the SAFOD data to our knowledge base by selecting specific classes and attributes. The submitted data then become available for query as part of the knowledge base. The SAFOD BM2KB can be accessed from the main SAFOD website.

Web Content Accessibility of Consumer Health Information Web Sites for People with Disabilities: A Cross Sectional Evaluation

Parmanto, Bambang

2004-01-01

Background The World Wide Web (WWW) has become an increasingly essential resource for health information consumers. The ability to obtain accurate medical information online quickly, conveniently and privately provides health consumers with the opportunity to make informed decisions and participate actively in their personal care. Little is known, however, about whether the content of this online health information is equally accessible to people with disabilities who must rely on special devices or technologies to process online information due to their visual, hearing, mobility, or cognitive limitations. Objective To construct a framework for an automated Web accessibility evaluation; to evaluate the state of accessibility of consumer health information Web sites; and to investigate the possible relationships between accessibility and other features of the Web sites, including function, popularity and importance. Methods We carried out a cross-sectional study of the state of accessibility of health information Web sites to people with disabilities. We selected 108 consumer health information Web sites from the directory service of a Web search engine. A measurement framework was constructed to automatically measure the level of Web Accessibility Barriers (WAB) of Web sites following Web accessibility specifications. We investigated whether there was a difference between WAB scores across various functional categories of the Web sites, and also evaluated the correlation between the WAB and Alexa traffic rank and Google Page Rank of the Web sites. Results We found that none of the Web sites we looked at are completely accessible to people with disabilities, i.e., there were no sites that had no violation of Web accessibility rules. However, governmental and educational health information Web sites do exhibit better Web accessibility than the other categories of Web sites (P < 0.001). We also found that the correlation between the WAB score and the popularity of a Web site is statistically significant (r = 0.28, P < 0.05), although there is no correlation between the WAB score and the importance of the Web sites (r = 0.15, P = 0.111). Conclusions Evaluation of health information Web sites shows that no Web site scrupulously abides by Web accessibility specifications, even for entities mandated under relevant laws and regulations. Government and education Web sites show better performance than Web sites among other categories. Accessibility of a Web site may have a positive impact on its popularity in general. However, the Web accessibility of a Web site may not have a significant relationship with its importance on the Web. PMID:15249268

On 21 August 2017, a solar eclipse occurred over the continental United States resulting in a rapid reduction and subsequent increase of solar radiation over a large region of the country. The eclipse's effect on the land-atmosphere system is documented in unprecedented detail using a unique array of sensors deployed at three sites in north-central Oklahoma. The observations showed that turbulent fluxes of heat and momentum at the surface responded quickly to the change in solar radiation. The decrease in the sensible heat flux resulted in a decrease in the air temperature below 200 m, and a large decrease in turbulent motions throughout the boundary layer. Furthermore, the turbulent mixing in the boundary layer lagged behind the change in the surface fluxes, and this lag depended on the height above the surface. The turbulent motions increased and the convective boundary layer was reestablished as the sensible heat flux recovered.

Totality swept across Indonesia and into the Pacific on 2016 March 9, lasting up to 2 min 45 s on Ternate in the Spice Islands (Malukus). I provide a first report on our observations. Our scientific goal is to follow changes in the corona over the solar-activity cycle, now past its 2012 and 2014 double peak, and to measure temporal changes in the corona on the scale of minutes or hours by comparing eclipse observations made at several sites along the path. I also discuss the near-simultaneous coronal observations made with SOHO/LASCO, SDO/AIA, STEREO/SECCHI, PROBA2/SWAP, and Hinode XRT.For the forthcoming 2017 eclipse, we acknowledge grants to JMP and Williams College from the Solar Terrestrial Program of the Atmospheric and Geospace Sciences Division of the National Science Foundation and from the Committee for Research and Exploration of the National Geographic Society.

The eclipses of HATS551-027 were first identified by observations from the HATSouth survey (Bakos et al. 2013PASP..125..154B). HATSouth is a global network of identical, fully robotic telescopes, providing continuous monitoring of selected 128 deg2 fields of the southern sky. A total of 16622 observations of HATS551-027 were obtained from HATSouth units HS-1, HS-2 in Chile, HS-3, HS-4 in Namibia, and HS-6 in Australia from 2009 September to 2010 September. Two secondary eclipses of HATS551-027 were observed by the Merope camera on 2-m Faulkes Telescope South (FTS), at Siding Spring Observatory, on 2012 December 12 and 2013 March 20. A near-complete primary eclipse of HATS551-027 was observed by the SITe#3 camera on the Swope 1 m telescope at Las Campanas Observatory, Chile, on 2013 February 26. (1 data file).

2017-12-01

The spectral emission of the infrared solar corona is the most promising direct diagnostic of the coronal magnetic field, and yet remains poorly measured. During the 2017 total solar eclipse, we will perform the first spectral survey of the IR corona using the NCAR Airborne Interferometer. This Fourier Transform Infrared Spectrometer is configured to observe the coronal spectrum from 1.5 to 5.5 microns at R 10,000 from a ground-based site. The location is atop Casper Mountain, Wyoming (42.73ºN, 106.32ºW, 2400 masl), 8 km from the center-line of totality. In this presentation, we will outline the need for such measurements, describe the instrument design and adaptation for the eclipse measurement, observation scheme, and present preliminary results. We will also discuss implications for observing infrared coronal lines from the ground, for example with the upcoming DKIST facility.

Spirit View of Phobos Eclipse, Sol 675

NASA Technical Reports Server (NTRS)

2005-01-01

[figure removed for brevity, see original site] Annotated Spirit View of Phobos Eclipse, Sol 675

NASA's Mars Exploration Rover Spirit observed the Martian moon Phobos entering the shadow of Mars during the night of the rover's 675th sol (Nov. 27, 2005). The panoramic camera captured 16 images, spaced 10 seconds apart, covering the period from when Phobos was in full sunlight to when it was entirely in shadow. As with our own Moon during lunar eclipses on Earth, even when in the planet's shadow, Phobos was not entirely dark. The small amount of light still visible from Phobos is a kind of 'Mars-shine' -- sunlight reflected through Mars' atmosphere and into the shadowed region.

This view is a time-lapse composite of images taken 20 seconds apart, showing the movement of Phobos from left to right. (At 10 seconds apart, the images of the moon overlap each other.) Scientists are using information about the precise timing of Martian moon eclipses gained from observations such as these to refine calculations about the orbital path of Phobos. The precise position of Phobos will be important to any future spacecraft taking detailed pictures of the moon or landing on its surface.

Raspberry Pi Eclipse Experiments

Chizek Frouard, Malynda

2018-01-01

The 21 August 2017 solar eclipse was an excellent opportunity for electronics and science enthusiasts to collect data during a fascinating phenomenon. With my recent personal interest in Raspberry Pis, I thought measuring how much the temperature and illuminance changes during a total solar eclipse would be fun and informational.Previous observations of total solar eclipses have remarked on the temperature drop during totality. Illuminance (ambient light) varies over 7 orders of magnitude from day to night and is highly dependent on relative positions of Sun, Earth, and Moon. I wondered whether totality was really as dark as night.Using a Raspberry Pi Zero W, a Pimoroni Enviro pHAT, and a portable USB charger, I collected environmental temperature; CPU temperature (because the environmental temperature sensor sat very near the CPU on the Raspberry Pi); barometric pressure; ambient light; R, G, and B colors; and x, y, and z acceleration (for marking times when I moved the sensor) data at a ~15 second cadence starting at about 5 am until 1:30 pm from my eclipse observation site in Glendo, WY. Totality occurred from 11:45 to 11:47 am, lasting about 2 minutes and 30 seconds.The Raspberry Pi recorded a >20 degree F drop in temperature during the eclipse, and the illuminance during totality was equivalent to twilight measurements earlier in the day. A limitation in the ambient light sensor prevented accurate measurements of broad daylight and most of the partial phase of the eclipse, but an alternate ambient light sensor combined with the Raspberry Pi setup would make this a cost-efficient set-up for illuminance studies.I will present data from the ambient light sensor, temperature sensor, and color sensor, noting caveats from my experiments, lessons learned for next time, and suggestions for anyone who wants to perform similar experiments for themselves or with a classroom.

Total solar eclipse effects on VLF signals: Observations and modeling

NASA Astrophysics Data System (ADS)

Clilverd, Mark A.; Rodger, Craig J.; Thomson, Neil R.; Lichtenberger, János; Steinbach, Péter; Cannon, Paul; Angling, Matthew J.

During the total solar eclipse observed in Europe on August 11, 1999, measurements were made of the amplitude and phase of four VLF transmitters in the frequency range 16-24 kHz. Five receiver sites were set up, and significant variations in phase and amplitude are reported for 17 paths, more than any previously during an eclipse. Distances from transmitter to receiver ranged from 90 to 14,510 km, although the majority were <2000 km. Typically, positive amplitude changes were observed throughout the whole eclipse period on path lengths <2000 km, while negative amplitude changes were observed on paths >10,000 km. Negative phase changes were observed on most paths, independent of path length. Although there was significant variation from path to path, the typical changes observed were ~3 dB and ~50°. The changes observed were modeled using the Long Wave Propagation Capability waveguide code. Maximum eclipse effects occurred when the Wait inverse scale height parameter β was 0.5 km-1 and the effective ionospheric height parameter H' was 79 km, compared with β=0.43km-1 and H'=71km for normal daytime conditions. The resulting changes in modeled amplitude and phase show good agreement with the majority of the observations. The modeling undertaken provides an interpretation of why previous estimates of height change during eclipses have shown such a range of values. A D region gas-chemistry model was compared with electron concentration estimates inferred from the observations made during the solar eclipse. Quiet-day H' and β parameters were used to define the initial ionospheric profile. The gas-chemistry model was then driven only by eclipse-related solar radiation levels. The calculated electron concentration values at 77 km altitude throughout the period of the solar eclipse show good agreement with the values determined from observations at all times, which suggests that a linear variation in electron production rate with solar ionizing radiation is reasonable. At times of minimum electron concentration the chemical model predicts that the D region profile would be parameterized by the same β and H' as the LWPC model values, and rocket profiles, during totality and can be considered a validation of the chemical processes defined within the model.

Analysis of pathology department Web sites and practical recommendations.

Nero, Christopher; Dighe, Anand S

2008-09-01

There are numerous customers for pathology departmental Web sites, including pathology department staff, clinical staff, residency applicants, job seekers, and other individuals outside the department seeking department information. Despite the increasing importance of departmental Web sites as a means of distributing information, no analysis has been done to date of the content and usage of pathology department Web sites. In this study, we analyzed pathology department Web sites to examine the elements present on each site and to evaluate the use of search technology on these sites. Further, we examined the usage patterns of our own departmental Internet and internet Web sites to better understand the users of pathology Web sites. We reviewed selected departmental pathology Web sites and analyzed their content and functionality. Our institution's departmental pathology Web sites were modified to enable detailed information to be stored regarding users and usage patterns, and that information was analyzed. We demonstrate considerable heterogeneity in departmental Web sites with many sites lacking basic content and search features. In addition, we demonstrate that increasing the traffic of a department's informational Web sites may result in reduced phone inquiries to the laboratory. We propose recommendations for pathology department Web sites to maximize promotion of a department's mission. A departmental pathology Web site is an essential communication tool for all pathology departments, and attention to the users and content of the site can have operational impact.

Nearly half of branded Web sites analyzed used designated children's areas to market food and beverages to children, 87% of which were of low nutritional quality. Nutrition professionals should advocate the use of advertising techniques to encourage healthful food choices for children.

Study of medicine 2.0 due to Web 2.0?! - Risks and opportunities for the curriculum in Leipzig

PubMed Central

Hempel, Gunther; Neef, Martin; Rotzoll, Daisy; Heinke, Wolfgang

2013-01-01

Web 2.0 is changing the study of medicine by opening up totally new ways of learning and teaching in an ongoing process. Global social networking services like Facebook, YouTube, Flickr, Google Drive and Xing already play an important part in communication both among students and between students and teaching staff. Moreover, local portals (such as the platform [http://www.leipzig-medizin.de] established in 2003) have also caught on and in some cases eclipsed the use of the well-known location-independent social media. The many possibilities and rapid changes brought about by social networks need to be publicized within medical faculties. Therefore, an E-learning and New Media Working Group was set up at the Faculty of Medicine of Universität Leipzig in order to harness the opportunities of Web 2.0, analyse the resulting processes of change in the study of medicine, and curb the risks of the Internet. With Web 2.0 and the social web already influencing the study of medicine, the opportunities of the Internet now need to be utilized to improve the teaching of medicine. PMID:23467440

Comparison of long-term numerical simulations at the Ketzin pilot site using the Schlumberger ECLIPSE and LBNL TOUGH2 simulators

NASA Astrophysics Data System (ADS)

Kempka, T.; Norden, B.; Tillner, E.; Nakaten, B.; Kühn, M.

2012-04-01

Geological modelling and dynamic flow simulations were conducted at the Ketzin pilot site showing a good agreement of history matched geological models with CO2 arrival times in both observation wells and timely development of reservoir pressure determined in the injection well. Recently, a re-evaluation of the seismic 3D data enabled a refinement of the structural site model and the implementation of the fault system present at the top of the Ketzin anticline. The updated geological model (model size: 5 km x 5 km) shows a horizontal discretization of 5 x 5 m and consists of three vertical zones, with the finest discretization at the top (0.5 m). According to the revised seismic analysis, the facies modelling to simulate the channel and floodplain facies distribution at Ketzin was updated. Using a sequential Gaussian simulator for the distribution of total and effective porosities and an empiric porosity-permeability relationship based on site and literature data available, the structural model was parameterized. Based on this revised reservoir model of the Stuttgart formation, numerical simulations using the TOUGH2-MP/ECO2N and Schlumberger Information Services (SIS) ECLIPSE 100 black-oil simulators were undertaken in order to evaluate the long-term (up to 10,000 years) migration of the injected CO2 (about 57,000 t at the end of 2011) and the development of reservoir pressure over time. The simulation results enabled us to quantitatively compare both reservoir simulators based on current operational data considering the long-term effects of CO2 storage including CO2 dissolution in the formation fluid. While the integration of the static geological model developed in the SIS Petrel modelling package into the ECLIPSE simulator is relatively flawless, a work-flow allowing for the export of Petrel models into the TOUGH2-MP input file format had to be implemented within the scope of this study. The challenge in this task was mainly determined by the presence of a complex faulted system in the revised reservoir model demanding for an integrated concept to deal with connections between the elements aligned to faults in the TOUGH2-MP simulator. Furthermore, we developed a methodology to visualize and compare the TOUGH2-MP simulation results with those of the Eclipse simulator using the Petrel software package. The long-term simulation results of both simulators are generally in good agreement. Spatial and timely migration of the CO2 plume as well as residual gas saturation are almost identical for both simulators, even though a time-dependent approach of CO2 dissolution in the formation fluid was chosen in the ECLIPSE simulator. Our results confirmed that a scientific open-source simulator as the TOUGH2-MP software package is capable to provide the same accuracy as the industrial standard simulator ECLIPSE 100. However, the computational time and additional efforts to implement a suitable workflow for using the TOUGH2-MP simulator are significantly higher, while the open-source concept of TOUGH2 provides more flexibility regarding process adaptation.

STRUCTURE AND DYNAMICS OF THE 2010 JULY 11 ECLIPSE WHITE-LIGHT CORONA

DOE Office of Scientific and Technical Information (OSTI.GOV)

Pasachoff, J. M.; Rusin, V.; Saniga, M.

The white-light corona (WLC) during the total solar eclipse on 2010 July 11 was observed by several teams in the Moon's shadow stretching across the Pacific Ocean and a number of isolated islands. We present a comparison of the WLC as observed by eclipse teams located on the Tatakoto Atoll in French Polynesia and on Easter Island, 83 minutes later, combined with near-simultaneous space observations. The eclipse was observed at the beginning of the solar cycle, not long after solar minimum. Nevertheless, the solar corona shows a plethora of different features (coronal holes, helmet streamers, polar rays, very faint loopsmore » and radial-oriented thin streamers, a coronal mass ejection, and a puzzling 'curtain-like' object above the north pole). Comparing the observations from the two sites enables us to detect some dynamic phenomena. The eclipse observations are further compared with a hairy-ball model of the magnetic field and near-simultaneous images from the Atmospheric Imaging Assembly on NASA's Solar Dynamics Observatory, the Extreme Ultraviolet Imager on NASA's Solar Terrestrial Relations Observatory, the Sun Watcher, using Active Pixel System Detector and Image Processing on ESA's PRoject for Onboard Autonomy, and the Naval Research Laboratory's Large Angle and Spectrometric Coronagraph on ESA's Solar and Heliospheric Observatory. The Ludendorff flattening coefficient is 0.156, matching the expected ellipticity of coronal isophotes at 2 Rs{sub un}, for this rising phase of the solar-activity cycle.« less

Development of a laboratory niche Web site.

PubMed

Dimenstein, Izak B; Dimenstein, Simon I

2013-10-01

This technical note presents the development of a methodological laboratory niche Web site. The "Grossing Technology in Surgical Pathology" (www.grossing-technology.com) Web site is used as an example. Although common steps in creation of most Web sites are followed, there are particular requirements for structuring the template's menu on methodological laboratory Web sites. The "nested doll principle," in which one object is placed inside another, most adequately describes the methodological approach to laboratory Web site design. Fragmentation in presenting the Web site's material highlights the discrete parts of the laboratory procedure. An optimally minimal triad of components can be recommended for the creation of a laboratory niche Web site: a main set of media, a blog, and an ancillary component (host, contact, and links). The inclusion of a blog makes the Web site a dynamic forum for professional communication. By forming links and portals, cloud computing opens opportunities for connecting a niche Web site with other Web sites and professional organizations. As an additional source of information exchange, methodological laboratory niche Web sites are destined to parallel both traditional and new forms, such as books, journals, seminars, webinars, and internal educational materials.

'Mars-shine'

NASA Technical Reports Server (NTRS)

2005-01-01

[figure removed for brevity, see original site] 'Mars-shine' Composite

NASA's Mars Exploration Rover Spirit continues to take advantage of favorable solar power conditions to conduct occasional nighttime astronomical observations from the summit region of 'Husband Hill.'

Spirit has been observing the martian moons Phobos and Deimos to learn more about their orbits and surface properties. This has included observing eclipses. On Earth, a solar eclipse occurs when the Moon's orbit takes it exactly between the Sun and Earth, casting parts of Earth into shadow. A lunar eclipse occurs when the Earth is exactly between the Sun and the Moon, casting the Moon into shadow and often giving it a ghostly orange-reddish color. This color is created by sunlight reflected through Earth's atmosphere into the shadowed region. The primary difference between terrestrial and martian eclipses is that Mars' moons are too small to completely block the Sun from view during solar eclipses.

Recently, Spirit observed a 'lunar' eclipse on Mars. Phobos, the larger of the two martian moons, was photographed while slipping into the shadow of Mars. Jim Bell, the astronomer in charge of the rover's panoramic camera (Pancam), suggested calling it a 'Phobal' eclipse rather than a lunar eclipse as a way of identifying which of the dozens of moons in our solar system was being cast into shadow.

With the help of the Jet Propulsion Laboratory's navigation team, the Pancam team planned instructions to Spirit for acquiring the views shown here of Phobos as it entered into a lunar eclipse on the evening of the rover's 639th martian day, or sol (Oct. 20, 2005) on Mars. This image is a time-lapse composite of eight Pancam images of Phobos moving across the martian sky. The entire eclipse lasted more than 26 minutes, but Spirit was able to observe only in the first 15 minutes. During the time closest to the shadow crossing, Spirit's cameras were programmed to take images every 10 seconds.

In the first three images, Phobos was in sunlight, moving toward the upper right. After a 100-second delay while Spirit's computer processed the first three images, the rover then took the fourth image, showing Phobos just starting to enter the darkness of the martian shadow. At that point, an observer sitting on Phobos and looking back toward the Sun would have seen a spectacular sunset! In the fifth image, Phobos appeared like a crescent, almost completely shrouded in darkness.

In the last three images, Phobos had slipped entirely into the shadow of Mars. However, as with our own Moon during lunar eclipses on Earth, it was not entirely dark. The small amount of light still visible from Phobos is a kind of 'Mars-shine' -- sunlight reflected through Mars' atmosphere and into the shadowed region.

Rover scientists took some images later in the sequence to try to figure out if this 'Mars-shine' made Phobos colorful while in eclipse, but they'll need more time to complete the analysis because the signal levels are so low. Meanwhile, they will use the information on the timing of the eclipse to refine the orbital path of Phobos. The precise position of Phobos will be important to any future spacecraft taking detailed pictures of the moon or landing on its surface. In the near future it might be possible for one of the rovers to take images of a 'Deimal' eclipse to learn more about Mars' other enigmatic satellite, Deimos, as well.

The Internet is a frequently used source of drug information, including among people with mental disorders. Online drug information may be narrow in scope, incomplete, and contain errors of omission. To evaluate the quality of online antidepressant drug information in English and Finnish. Forty Web sites were identified using the search terms antidepressants and masennuslääkkeet in English and Finnish, respectively. Included Web sites (14 English, 8 Finnish) were evaluated for aesthetics, interactivity, content coverage, and content correctness using published criteria. All Web sites were assessed using the Date, Author, References, Type, Sponsor (DARTS) and DISCERN quality assessment tools. English and Finnish Web sites had similar aesthetics, content coverage, and content correctness scores. English Web sites were more interactive than Finnish Web sites (P<.05). Overall, adverse drug reactions were covered on 21 of 22 Web sites; however, drug-alcohol interactions were addressed on only 9 of 22 Web sites, and dose was addressed on only 6 of 22 Web sites. Few (2/22 Web sites) provided incorrect information. The DISCERN score was significantly correlated with content coverage (r=0.670, P<.01), content correctness (r=0.663, P<.01), and the DARTS score (r=0.459, P<.05). No Web site provided information about all aspects of antidepressant treatment. Nevertheless, few Web sites provided incorrect information. Both English and Finnish Web sites were similar in terms of aesthetics, content coverage, and content correctness. Copyright © 2012 Elsevier Inc. All rights reserved.

CATE 2016 Indonesia: Camera, Software, and User Interface

NASA Astrophysics Data System (ADS)

Kovac, S. A.; Jensen, L.; Hare, H. S.; Mitchell, A. M.; McKay, M. A.; Bosh, R.; Watson, Z.; Penn, M.

2016-12-01

The Citizen Continental-America Telescopic Eclipse (Citizen CATE) Experiment will use a fleet of 60 identical telescopes across the United States to image the inner solar corona during the 2017 total solar eclipse. For a proof of concept, five sites were hosted along the path of totality during the 2016 total solar eclipse in Indonesia. Tanjung Pandan, Belitung, Indonesia was the first site to experience totality. This site had the best seeing conditions and focus, resulting in the highest quality images. This site proved that the equipment that is going to be used is capable of recording high quality images of the solar corona. Because 60 sites will be funded, each set up needs to be cost effective. This requires us to use an inexpensive camera, which consequently has a small dynamic range. To compensate for the corona's intensity drop off factor of 1,000, images are taken at seven frames per second, at exposures 0.4ms, 1.3ms, 4.0ms, 13ms, 40ms, 130ms, and 400ms. Using MatLab software, we are able to capture a high dynamic range with an Arduino that controls the 2448 x 2048 CMOS camera. A major component of this project is to train average citizens to use the software, meaning it needs to be as user friendly as possible. The CATE team is currently working with MathWorks to create a graphic user interface (GUI) that will make data collection run smoothly.

Accessibility and content of individualized adult reconstructive hip and knee/musculoskeletal oncology fellowship web sites.

PubMed

Young, Bradley L; Cantrell, Colin K; Patt, Joshua C; Ponce, Brent A

2018-06-01

Accessible, adequate online information is important to fellowship applicants. Program web sites can affect which programs applicants apply to, subsequently altering interview costs incurred by both parties and ultimately impacting rank lists. Web site analyses have been performed for all orthopaedic subspecialties other than those involved in the combined adult reconstruction and musculoskeletal (MSK) oncology fellowship match. A complete list of active programs was obtained from the official adult reconstruction and MSK oncology society web sites. Web site accessibility was assessed using a structured Google search. Accessible web sites were evaluated based on 21 previously reported content criteria. Seventy-four adult reconstruction programs and 11 MSK oncology programs were listed on the official society web sites. Web sites were identified and accessible for 58 (78%) adult reconstruction and 9 (82%) MSK oncology fellowship programs. No web site contained all content criteria and more than half of both adult reconstruction and MSK oncology web sites failed to include 12 of the 21 criteria. Several programs participating in the combined Adult Reconstructive Hip and Knee/Musculoskeletal Oncology Fellowship Match did not have accessible web sites. Of the web sites that were accessible, none contained comprehensive information and the majority lacked information that has been previously identified as being important to perspective applicants.

The Internet is a widely used information resource for patients with inflammatory bowel disease, but there is variation in the quality of Web sites that have patient information regarding Crohn's disease and ulcerative colitis. The purpose of the current study is to systematically evaluate the quality of these Web sites. The top 50 Web sites appearing in Google using the terms "Crohn's disease" or "ulcerative colitis" were included in the study. Web sites were evaluated using a (a) Quality Evaluation Instrument (QEI) that awarded Web sites points (0-107) for specific information on various aspects of inflammatory bowel disease, (b) a five-point Global Quality Score (GQS), (c) two reading grade level scores, and (d) a six-point integrity score. Thirty-four Web sites met the inclusion criteria, 16 Web sites were excluded because they were portals or non-IBD oriented. The median QEI score was 57 with five Web sites scoring higher than 75 points. The median Global Quality Score was 2.0 with five Web sites achieving scores of 4 or 5. The average reading grade level score was 11.2. The median integrity score was 3.0. There is marked variation in the quality of the Web sites containing information on Crohn's disease and ulcerative colitis. Many Web sites suffered from poor quality but there were five high-scoring Web sites.

Personality in cyberspace: personal Web sites as media for personality expressions and impressions.

PubMed

Marcus, Bernd; Machilek, Franz; Schütz, Astrid

2006-06-01

This research examined the personality of owners of personal Web sites based on self-reports, visitors' ratings, and the content of the Web sites. The authors compared a large sample of Web site owners with population-wide samples on the Big Five dimensions of personality. Controlling for demographic differences, the average Web site owner reported being slightly less extraverted and more open to experience. Compared with various other samples, Web site owners did not generally differ on narcissism, self-monitoring, or self-esteem, but gender differences on these traits were often smaller in Web site owners. Self-other agreement was highest with Openness to Experience, but valid judgments of all Big Five dimensions were derived from Web sites providing rich information. Visitors made use of quantifiable features of the Web site to infer personality, and the cues they utilized partly corresponded to self-reported traits. Copyright 2006 APA, all rights reserved.

Eclipse 2017: Through the Eyes of NASA

NASA Astrophysics Data System (ADS)

Mayo, Louis; NASA Heliophysics Education Consortium

2017-10-01

The August 21, 2017 total solar eclipse across America was, by all accounts, the biggest science education program ever carried out by NASA, significantly larger than the Curiosity Mars landing and the New Horizons Pluto flyby. Initial accounting estimates over two billion people reached and website hits exceeding five billion. The NASA Science Mission Directorate spent over two years planning and developing this enormous public education program, establishing over 30 official NASA sites along the path of totality, providing imagery from 11 NASA space assets, two high altitude aircraft, and over 50 high altitude balloons. In addition, a special four focal plane ground based solar telescope was developed in partnership with Lunt Solar Systems that observed and processed the eclipse in 6K resolution. NASA EDGE and NASA TV broadcasts during the entirity of totality across the country reached hundreds of millions, world wide.This talk will discuss NASA's strategy, results, and lessons learned; and preview some of the big events we plan to feature in the near future.

Russell, Amina; Van Woensel, William; Abidi, Samina Raza

2015-01-01

The objective of this study is to determine if shared decisions for managing non-critical chronic illness, made through an online biomedical technology intervention, us feasible and usable. The technology intervention incorporates behavioural and decision theories to increase patient engagement, and ultimately long term adherence to health behaviour change. We devised the iheart web intervention as a "proof of concept" in five phases. The implementation incorporates the Vaadin web application framework, Drools, EclipseLink and a MySQL database. Two-thirds of the study participants favoured the technology intervention, based on Likert-scale questions from a post-study questionnaire. Qualitative analysis of think aloud feedback, video screen captures and open-ended questions from the post-study questionnaire uncovered six main areas or themes for improvement. We conclude that online shared decisions for managing a non-critical chronic illness are feasible and usable through the iheart web intervention.

The Citizen Continental-America Telescopic Eclipse (CATE) Experiment is a team of students, citizen scientists and professional astronomers who will operate 60 identical telescopes distributed across the country in the path of totality from Oregon to South Carolina during the 21 August 2017 solar eclipse. The project goal is to produce a 90-minute time sequence of calibrated white light images of the solar corona. This unprecedented, continuous, temporal coverage during totality will allow us to address questions related to the dynamics in the inner 2.5 Rsun of the corona.Field testing of the equipment began with one setup located on the Faroe Islands during the March 2015 total solar eclipse. Here we report on the more recent March 2016 eclipse where five CATE teams were sent to Indonesia. This group included university undergraduate students, their faculty mentors and other professional scientists. CATE completed a successful field testing of multiple sites near the equator that were distributed over 20 degrees in longitude. We conclude our discussion with how the experience gained over the past two years is being put to use as we prepare for the full implementation of the CATE Network in August 2017.This work was supported in part by funding from NASA SMD grant NNX16AB92A and the NSF REU program through AST-1460743.

How 352 Japanese university students regard web-site information was investigated by two kinds of survey. Application of correspondence analysis and cluster analysis to the questionnaire responses to the web-site advertisement showed students regarded a web-site as a new alien medium which is different from current media. Students regarded web-sites as simply complicated, intellectual, and impermanent, or not memorable. Students got precise information from web-sites but they did not use it in making decisions to purchase goods.

A search at two eclipses for short-period waves that heat the corona

NASA Astrophysics Data System (ADS)

Pasachoff, Jay M.; Babcock, Bryce A.; Russell, Kevin D.; McConnochie, Timothy H.; Diaz, J. Sebastian

2000-08-01

As part of a study of the cause of solar coronal heating, we searched for high-frequency (~1 Hz) intensity oscillations in coronal loops in the [Fexiv] coronal green line. We summarize results from observations made at the 3 November 1994, total solar eclipse from the International Astronomical Union site in Putre, Chile, through partly cloudy skies, and at the 26 February 1998 total solar eclipse from Nord, Aruba, through clear skies. We discuss the image reduction and analysis of two simultaneous series of coronal CCD images digitized at 10 Hz for a total time of 160 s in Chile. One series of images was taken through a filter isolating the 5303 Å[Fexiv] coronal green line and the other through a 100 Å filter in the nearby K-corona continuum. We then discuss the modifications made for the 1998 eclipse, and the image reduction and analysis for those image sequences. After standard calibrations and image alignment of both data sets, we use Fourier analysis to search in the [Fexiv] channel for intensity oscillations in loops at the base of the corona. Such oscillations in the 1-Hz range are predicted as a result of density fluctuations from the resonant absorption of MHD waves. The dissipation of a significant amount of mechanical energy from the photosphere into the corona through this mechanism could provide sufficient energy to heat the corona. At neither eclipse do we find evidence for oscillations in the [Fexiv] green line at a level greater than 2% of coronal intensity.

Web sites for postpartum depression: convenient, frustrating, incomplete, and misleading.

PubMed

Summers, Audra L; Logsdon, M Cynthia

2005-01-01

To evaluate the content and the technology of Web sites providing information on postpartum depression. Eleven search engines were queried using the words "Postpartum Depression." The top 10 sites in each search engine were evaluated for correct content and technology using the Web Depression Tool, based on the Technology Assessment Model. Of the 36 unique Web sites located, 34 were available to review. Only five Web sites provided >75% correct responses to questions that summarized the current state of the science for postpartum depression. Eleven of the Web sites contained little or no useful information about postpartum depression, despite being among the first 10 Web sites listed by the search engine. Some Web sites contained possibly harmful suggestions for treatment of postpartum depression. In addition, there are many problems with the technology of Web sites providing information on postpartum depression. A better Web site for postpartum depression is necessary if we are to meet the needs of consumers for accurate and current information using technology that enhances learning. Since patient education is a core competency for nurses, it is essential that nurses understand how their patients are using the World Wide Web for learning and how we can assist our patients to find appropriate sites containing correct information.

The Citizen CATE Experiment for the 2017 Total Solar Eclipse

NASA Astrophysics Data System (ADS)

Penn, M. J.

2015-12-01

The path of the total solar eclipse of 21 August 2017 passes over about 10 million homes in the USA. Tens of millions more people will travel to the path of totality to view the eclipse first-hand. Using TV and the internet broadcasts, hundreds of millions of people will watch the eclipse, making the event the most viewed astronomical event in the history of mankind. The Citizen Continental-America Telescopic Eclipse (CATE) Experiment for 2017 is being developed at the National Solar Observatory in partnership with universities, schools, astronomy clubs, and corporations. The CATE experiment will use more than 60 identical telescopes equipped with digital cameras positioned from Oregon to South Carolina to image the solar corona. The project will then splice these images together to show the corona during a 90-minute period, revealing for the first time the plasma dynamics of the inner solar corona. The goals for the highly leveraged CATE experiment are diverse and range from providing an authentic STEM research experience for students and lifelong learners, to making state-of-the-art solar coronal observations of the plasma dynamics of coronal polar plumes, to increasing the US scientific literacy. A key goal of this experiment is to donate the telescope and camera system to the volunteer who collects data with it during the total eclipse. The instrument will be then used for a variety of follow-up citizen science projects in astronomy, ranging from solar to cometary to variable star observations. For this reason no government funding is being sought for the equipment costs, but rather private and corporate sources are being developed. The data collected for the 2017 eclipse will be freely available to the scientific, education and amateur astronomy communities. Crowd sourcing the data collection is an essential part of this project, as there are not enough solar physicists in this country to collect these observations. Finally, each site is expected to collect about 10 Gbytes of science data and 10 Gbytes of calibration data, resulting in 1.2 Tbytes of data for the project.

Characteristics of food industry web sites and "advergames" targeting children.

2010-01-01

To assess the content of food industry Web sites targeting children by describing strategies used to prolong their visits and foster brand loyalty; and to document health-promoting messages on these Web sites. A content analysis was conducted of Web sites advertised on 2 children's networks, Cartoon Network and Nickelodeon. A total of 290 Web pages and 247 unique games on 19 Internet sites were examined. Games, found on 81% of Web sites, were the most predominant promotion strategy used. All games had at least 1 brand identifier, with logos being most frequently used. On average Web sites contained 1 "healthful" message for every 45 exposures to brand identifiers. Food companies use Web sites to extend their television advertising to promote brand loyalty among children. These sites almost exclusively promoted food items high in sugar and fat. Health professionals need to monitor food industry marketing practices used in "new media." Published by Elsevier Inc.

2009-02-01

In this study, three characteristics of Web sites were varied: types of banner ad, Web localization, and involvement in purchasing a product. The dependent variable was attitude toward the site. In laboratory experiments conducted in Thailand and Taiwan, participants browsed versions of a Web site containing different types of banner ads and products. As a within-participants factor, each participant browsed both a standardized English-language Web site and a localized Web site. Results showed that animated (rather than static) banner ads, localized versions (rather than a standardized version) of Web sites, and high (rather than low) product involvement led to favorable attitudes toward the site.

Namkung, Young; Almanza, Barbara A

2006-10-01

Despite a growing concern over food safety issues, as well as a growing dependence on the Internet as a source of information, little research has been done to examine the presence and relevance of food safety-related information on Web sites. The study reported here conducted Web site analysis in order to examine the current operational status of governmental Web sites on food safety issues. The study also evaluated Web site usability, especially information dimensionalities such as utility, currency, and relevance of content, from the perspective of the English-speaking consumer. Results showed that out of 192 World Health Organization members, 111 countries operated governmental Web sites that provide information about food safety issues. Among 171 searchable Web sites from the 111 countries, 123 Web sites (71.9 percent) were accessible, and 81 of those 123 (65.9 percent) were available in English. The majority of Web sites offered search engine tools and related links for more information, but their availability and utility was limited. In terms of content, 69.9 percent of Web sites offered information on foodborne-disease outbreaks, compared with 31.5 percent that had travel- and health-related information.

A New Scientific use of Total Eclipses of the Moon: Studies of the Generation and Loss of Atmospheres of Primitives Bodies

NASA Technical Reports Server (NTRS)

Mendillo, Michael

1999-01-01

This grant supported observational campaigns to record the size and brightness of the lunar atmosphere as seen in sodium gas (Na) emissions during the totality phase of lunar eclipses. Three eclipse events were attempted, two from the Mc Donald Observatory in Fort Davis Texas, and one from the site of Italy's Galileo National Telescope (GNT) in La Palma, in the Canary Islands. In all three cases, clear skies prevailed and excellent datasets were obtained. Following the observational component of the grant, a period of detailed processing and analysis began. Eclipse events were chosen for study because when the moon is in full phase it has been within the terrestrial magnetosphere for a few days, thereby shielded from solar wind impact upon its surface. Since sputtering of Na from the lunar regolith by solar wind particles had been proposed as a source of the Moon's atmosphere, this was a test of the mechanism. If the lunar Na appeared to be diminished in comparison to abundances seen at other phases (e.g., at quarter phase when the moon is directly in the solar wind), the solar wind sputtering would indeed be a major source of lunar Na. These experiments could not be conducted during any full moon night because scattering of bright moonlight is so strong that low-light-level imaging of the lunar atmosphere could not be achieved. Hence, the use of eclipses. The final result of these experiments was, for once, clear and unambiguous. The robust size and Na brightness levels measured during all of the eclipses showed that solar wind sputtering could not be a major source of the lunar atmosphere. A major paper on this conclusion was published in ICARUS, and an oral presentation of partial results given at the The Three Galileos conference in Padova (Italy) in January 1997 and at the DPS meeting in Cambridge, MA, in July 1997.

ΔT and tidal acceleration values from three european medieval eclipses

NASA Astrophysics Data System (ADS)

Martinez, M. J.; Marco, F. J.

2011-10-01

There are many possible reasons for the fact that the rate of rotation of the Earth is slowly decreasing in time, being the most important the tidal friction. Since Universal Time (UT) is a time scale based on the rotation of the Earth and ΔT defined as the difference between the uniform time-scale (Dynamical Time), and the Universal Time, clearly that ΔT will vary with time. The problem is that this variation is not uniform, existing irregular fluctuations. In addition, it is not possible to predict exact values for ΔT, being the only possibility its deduction a posteriori from observations. ΔT is strongly related with occultations and eclipses, because it is used for the calculation of exact times of the event, and for determining the position of the central line or the zone of visibility. In this sense, a value ΔT =3600s is roughly equivalent to a shift of 15. in longitude. Past values of ΔT can be deduced from historical astronomical observations such as ancient eclipses which have been widely studied by F.R. Stephenson [3] and [4] who has even obtained an approximation fitted with cubic splines for ΔT from -500 to +1950. This approximation is nowadays widely used in astronomical calculations. The derived relative error from ΔT obtained from ancient eclipsed is quite large, mainly because of the large width of the totality zone and the inaccuracy in the definition of the observational place. A possibility to partially solve these former problems is the analysis of total eclipse records from multiple sites, which could provide a narrow parameter range. In addition, The conjunct analysis of these astronomical phenomena is useful for determining a range of ΔT in function of the tidal acceleration of the Moon. Further discussion about these eclipses in under review.

Estimating the uncertainty of calculated out-of-field organ dose from a commercial treatment planning system.

PubMed

Wang, Lilie; Ding, George X

2018-06-12

Therapeutic radiation to cancer patients is accompanied by unintended radiation to organs outside the treatment field. It is known that the model-based dose algorithm has limitation in calculating the out-of-field doses. This study evaluated the out-of-field dose calculated by the Varian Eclipse treatment planning system (v.11 with AAA algorithm) in realistic treatment plans with the goal of estimating the uncertainties of calculated organ doses. Photon beam phase-space files for TrueBeam linear accelerator were provided by Varian. These were used as incident sources in EGSnrc Monte Carlo simulations of radiation transport through the downstream jaws and MLC. Dynamic movements of the MLC leaves were fully modeled based on treatment plans using IMRT or VMAT techniques. The Monte Carlo calculated out-of-field doses were then compared with those calculated by Eclipse. The dose comparisons were performed for different beam energies and treatment sites, including head-and-neck, lung, and pelvis. For 6 MV (FF/FFF), 10 MV (FF/FFF), and 15 MV (FF) beams, Eclipse underestimated out-of-field local doses by 30%-50% compared with Monte Carlo calculations when the local dose was <1% of prescribed dose. The accuracy of out-of-field dose calculations using Eclipse is improved when collimator jaws were set at the smallest possible aperture for MLC openings. The Eclipse system consistently underestimates out-of-field dose by a factor of 2 for all beam energies studied at the local dose level of less than 1% of prescribed dose. These findings are useful in providing information on the uncertainties of out-of-field organ doses calculated by Eclipse treatment planning system. © 2018 The Authors.

Evaluation of the content and accessibility of web sites for accredited orthopaedic sports medicine fellowships.

PubMed

Mulcahey, Mary K; Gosselin, Michelle M; Fadale, Paul D

2013-06-19

The Internet is a common source of information for orthopaedic residents applying for sports medicine fellowships, with the web sites of the American Orthopaedic Society for Sports Medicine (AOSSM) and the San Francisco Match serving as central databases. We sought to evaluate the web sites for accredited orthopaedic sports medicine fellowships with regard to content and accessibility. We reviewed the existing web sites of the ninety-five accredited orthopaedic sports medicine fellowships included in the AOSSM and San Francisco Match databases from February to March 2012. A Google search was performed to determine the overall accessibility of program web sites and to supplement information obtained from the AOSSM and San Francisco Match web sites. The study sample consisted of the eighty-seven programs whose web sites connected to information about the fellowship. Each web site was evaluated for its informational value. Of the ninety-five programs, fifty-one (54%) had links listed in the AOSSM database. Three (3%) of all accredited programs had web sites that were linked directly to information about the fellowship. Eighty-eight (93%) had links listed in the San Francisco Match database; however, only five (5%) had links that connected directly to information about the fellowship. Of the eighty-seven programs analyzed in our study, all eighty-seven web sites (100%) provided a description of the program and seventy-six web sites (87%) included information about the application process. Twenty-one web sites (24%) included a list of current fellows. Fifty-six web sites (64%) described the didactic instruction, seventy (80%) described team coverage responsibilities, forty-seven (54%) included a description of cases routinely performed by fellows, forty-one (47%) described the role of the fellow in seeing patients in the office, eleven (13%) included call responsibilities, and seventeen (20%) described a rotation schedule. Two Google searches identified direct links for 67% to 71% of all accredited programs. Most accredited orthopaedic sports medicine fellowships lack easily accessible or complete web sites in the AOSSM or San Francisco Match databases. Improvement in the accessibility and quality of information on orthopaedic sports medicine fellowship web sites would facilitate the ability of applicants to obtain useful information.

Assessment of the Monitor Unit Objective tool for VMAT in the Eclipse treatment planning system.

Jiménez-Puertas, Sara; Sánchez-Artuñedo, David; Hermida-López, Marcelino

2018-01-01

This work aims to achieve the highest possible monitor units (MU) reduction using the MU Objective tool included in the Eclipse treatment planning system, while preserving the plan quality. The treatment planning system Eclipse (Varian Medical Systems, Palo Alto, CA) includes a control mechanism for the number of monitor units of volumetric modulated arc therapy (VMAT) plans, named the MU Objective tool. Forty prostate plans, 20 gynecological plans and 20 head and neck plans designed with VMAT were retrospectively studied. Each plan ( base plan ) was optimized without using the MU Objective tool, and it was re-optimized with different values of the Maximum MU ( MaxMU ) parameter of the MU Objective tool. MU differences were analyzed with a paired samples t -test and changes in plan quality were assessed with a set of parameters for OARs and PTVs. The average relative MU difference [Formula: see text] considering all treatment sites, was the highest when MaxMU  = 400 (-4.2%, p  < 0.001). For prostate plans, the lowest [Formula: see text] was obtained (-3.7%, p  < 0.001). For head and neck plans [Formula: see text] was -7.3% ( p  < 0.001) and for gynecological plans [Formula: see text] was 7.0% ( p  = 0.002). Although similar MU reductions were observed for both sites, for some gynecological plans maximum differences were greater than 10%. All the assessed parameters for PTVs and OARs sparing showed average differences below 2%. For the three studied clinical sites, establishing MaxMU  = 400 led to the optimum MU reduction, maintaining the original dose distribution and dosimetric parameters practically unaltered.

A total eclipse swept across Queensland and other sites in northeastern Australia on the early morning of 14 November 2012, local time. We mounted equipment to observe coronal images and spectra during the approximately 2 minutes of totality, the former for comparison with spacecraft images and to fill in the doughnut of imaging not well covered with space coronagraphs. Matching weather statistics, viewing was spotty, and our best observations were from a last-minute inland site on the Tablelands, with some observations from a helicopter at 9000 feet altitude over our original viewing site at Miallo. Only glimpses of the corona were visible at our Port Douglas and Trinity Beach, Cairns, locations, with totality obscured from our sites at Newell and Miallo, though some holes in the clouds provided coronal views from Palm Cove and elsewhere along the coast. Preliminary analysis of the spectra again shows Fe XIV stronger than Fe X, as in 2010 but not earlier, a sign of solar maximum, as was the coronal shape. An intriguing CME is discernible in the SE.

A Model for the Sources of the Slow Solar Wind

NASA Astrophysics Data System (ADS)

Antiochos, Spiro K.; Mikic, Z.; Lionello, R.; Titov, V.; Linker, J.

2010-05-01

Models for the origin of the slow solar wind must account for two seemingly contradictory observations: The slow wind has the composition of the closed-field corona, implying that it originates at the open-closed field boundary layer, but it also has large angular width, up to 40 degrees. We propose a model that can explain both observations. The key idea is that the source of the slow wind at the Sun is a network of narrow (possibly singular) open-field corridors that map to a web of separatrices and quasi-separatrix layers in the heliosphere. We calculate with high numerical resolution, the quasi-steady solar wind and magnetic field for a Carrington rotation centered about the August 1, 2008 total solar eclipse. Our numerical results demonstrate that, at least for this time period, a web of separatrices (S-web) forms with sufficient density and extent in the heliosphere to account for the observed properties of the slow wind. We discuss the implications of our S-web model for the structure and dynamics of the corona and heliosphere, and propose further tests of the model. This work was supported, in part, by the NASA HTP, TR&T and SR&T programs.

2014-01-01

To update and extend prior work reviewing Web sites that discuss home drug testing for parents, and assess the quality of information that the Web sites provide, to assist them in deciding when and how to use home drug testing. We conducted a worldwide Web search that identified 8 Web sites providing information for parents on home drug testing. We assessed the information on the sites using a checklist developed with field experts in adolescent substance abuse and psychosocial interventions that focus on urine testing. None of the Web sites covered all the items on the 24-item checklist, and only 3 covered at least half of the items (12, 14, and 21 items, respectively). The remaining 5 Web sites covered less than half of the checklist items. The mean number of items covered by the Web sites was 11. Among the Web sites that we reviewed, few provided thorough information to parents regarding empirically supported strategies to effectively use drug testing to intervene on adolescent substance use. Furthermore, most Web sites did not provide thorough information regarding the risks and benefits to inform parents' decision to use home drug testing. Empirical evidence regarding efficacy, benefits, risks, and limitations of home drug testing is needed.

The objective of this study was to evaluate the quality and accuracy of sexual health information on crisis pregnancy center Web sites listed in state resource directories for pregnant women, and whether these Web sites specifically target adolescents. A survey of sexual health information presented on the Web sites of crisis pregnancy centers. Internet. Crisis pregnancy center Web sites. Evaluation of the sexual health information presented on crisis pregnancy center Web sites. Themes included statements that condoms are not effective, promotion of abstinence-only education, availability of comprehensive sexual education, appeal to a young audience, provision of comprehensive sexual health information, and information about sexually transmitted infections (STIs). Crisis pregnancy center Web sites provide inaccurate and misleading information about condoms, STIs, and methods to prevent STI transmission. This information might be particularly harmful to adolescents, who might be unable to discern the quality of sexual health information on crisis pregnancy center Web sites. Listing crisis pregnancy centers in state resource directories might lend legitimacy to the information on these Web sites. States should be discouraged from listing Web sites as an accurate source of information in their resource directories.

Depth-of-processing effects as college students use academic advising Web sites.

PubMed

Boatright-Horowitz, Su L; Langley, Michelle; Gunnip, Matthew

2009-06-01

This research examined students' cognitive and affective responses to an academic advising Web site. Specifically, we investigated whether exposure to our Web site increased student reports that they would access university Web sites to obtain various types of advising information. A depth-of-processing (DOP) manipulation revealed this effect as students engaged in semantic processing of Web content but not when they engaged in superficial examination of the physical appearance of the same Web site. Students appeared to scan online academic advising materials for information of immediate importance without noticing other information or hyperlinks (e.g., regarding internships and careers). Suggestions are presented for increasing the effectiveness of academic advising Web sites.

Presence of pro-tobacco messages on the Web.

PubMed

Hong, Traci; Cody, Michael J

2002-01-01

Ignored in the finalized Master Settlement Agreement (National Association of Attorneys General, 1998), the unmonitored, unregulated World Wide Web (Web) can operate as a major vehicle for delivering pro-tobacco messages, images, and products to millions of young consumers. A content analysis of 318 randomly sampled pro-tobacco Web sites revealed that tobacco has a pervasive presence on the Web, especially on e-commerce sites and sites featuring hobbies, recreation, and "fetishes." Products can be ordered online on nearly 50% of the sites, but only 23% of the sites included underage verification. Further, only 11% of these sites contain health warnings. Instead, pro-tobacco sites frequently associate smoking with "glamorous" and "alternative" lifestyles, and with images of young males and young (thin, attractive) females. Finally, many of the Web sites offered interactive site features that are potentially appealing to young Web users. Recommendations for future research and counterstrategies are discussed.

Improving Web Searches: Case Study of Quit-Smoking Web Sites for Teenagers

PubMed Central

Skinner, Harvey

2003-01-01

Background The Web has become an important and influential source of health information. With the vast number of Web sites on the Internet, users often resort to popular search sites when searching for information. However, little is known about the characteristics of Web sites returned by simple Web searches for information about smoking cessation for teenagers. Objective To determine the characteristics of Web sites retrieved by search engines about smoking cessation for teenagers and how information quality correlates with the search ranking. Methods The top 30 sites returned by 4 popular search sites in response to the search terms "teen quit smoking" were examined. The information relevance and quality characteristics of these sites were evaluated by 2 raters. Objective site characteristics were obtained using a page-analysis Web site. Results Only 14 of the 30 Web sites are of direct relevance to smoking cessation for teenagers. The readability of about two-thirds of the 14 sites is below an eighth-grade school level and they ranked significantly higher (Kendall rank correlation, tau = -0.39, P= .05) in search-site results than sites with readability above or equal to that grade level. Sites that ranked higher were significantly associated with the presence of e-mail address for contact (tau = -0.46, P= .01), annotated hyperlinks to external sites (tau = -0.39, P= .04), and the presence of meta description tag (tau = -0.48, P= .002). The median link density (number of external sites that have a link to that site) of the Web pages was 6 and the maximum was 735. A higher link density was significantly associated with a higher rank (tau = -0.58, P= .02). Conclusions Using simple search terms on popular search sites to look for information on smoking cessation for teenagers resulted in less than half of the sites being of direct relevance. To improve search efficiency, users could supplement results obtained from simple Web searches with human-maintained Web directories and learn to refine their searches with more advanced search syntax.

2015-01-01

Research has shown that up to 89% of parents used the Internet to seek health information regarding their child's medical condition. Much of the information on the Internet is valuable; however, the quality of health information is variable and unregulated. The aim of this study was to evaluate the quality and content of information about Perthes disease on the Internet using recognized scoring systems, identification of quality markers, and describe a novel specific score. We searched the top 3 search engines (Google, Yahoo!, and Bing) for the following keywords: "Perthes disease." Forty-five unique Web sites were identified. The Web sites were then categorized by type and assessed using the DISCERN score, the Journal of the American Medical Association (JAMA) benchmark criteria, and a novel Perthes-specific Content score. The presence of the Health On the Net (HON) code, a reported quality assurance marker, was noted. Of the Web sites analyzed, the Majority were Governmental and Nonprofit Organizations (NPO) (37.8%), followed by commercial Web sites (22.2%). Only 6 of the Web sites were HONcode certified. The mean DISCERN score was 53.1 (SD=9.0). The Governmental and NPO Web sites had the highest overall DISCERN scores followed closely by Physician Web sites. The mean JAMA benchmark criteria score was 2.1 (SD=1.2). Nine Web sites had maximal scores and the Academic Web sites had the highest overall JAMA benchmark scores. DISCERN scores, JAMA benchmark scores, and Perthes-specific Content scores were all greater for Web sites that bore the HONcode seal. The quality of information available online regarding Perthes disease is of variable quality. Governmental and NPO Web sites predominate and also provide higher quality content. The HONcode seal is a reliable indicator of Web site quality. Physicians should recommend the HONcode seal to their patients as a reliable indicator of Web site quality or, better yet, refer patients to sites they have personally reviewed. Supplying parents with a guide to health information on the Internet will help exclude Web sites as sources of misinformation.

2009-01-01

This catalog is a supplement to the "FiveMillenniumCanonofLunarEclipses." It includes additional information for each eclipse that could not be included in the original publication because of size limits. The data tabulated for each eclipse include the catalog number, canon plate number, calendar date, Terrestrial Dynamical Time of greatest eclipse, (Delta)T, lunation number, Saros number, eclipse type, Quincena Solar Eclipse parameter, gamma, penumbral and umbral eclipse magnitudes, durations of penumbral, partial and total eclipse phases, and geographic coordinates of greatest eclipse (latitude and longitude). The Canon and the Catalog both use the same solar and lunar ephemerides as well as the same values of (Delta)T. This 1-to-1 correspondence between them will enhance the value of each. The researcher may now search, evaluate, and compare eclipses graphically (Canon) or textually (Catalog).

The effects of Web site structure: the role of personal difference.

PubMed

Chung, Hwiman; Ahn, Euijin

2007-12-01

This study examined the effects of Web site structures in terms of advertising effectiveness- memory, attitude, and behavioral intentions. The primary research question for this study is, What type of Web site (Web ad) structure is most effective? In the pilot study, we tested the difference between two Web site structures, linear and interactive, in terms of traditional advertising effectiveness. Results from the pilot study did not support our research expectations. However, differences in terms of memory were noted between the two structures. After re-creating the Web site based on subjects' comments, in the final experiment, we examined the differences between the two structures and the moderating role of personality difference on the effects of Web site structure. The results confirm that participants' attitude, memory, and behavioral intentions were affected differently by the different Web site structures. However, some research hypotheses were not supported by the current data.

Efficacy of a Pilot Internet-Based Weight Management Program (H.E.A.L.T.H.) and Longitudinal Physical Fitness Data in Army Reserve Soldiers

Newton, Robert L; Han, Hongmei; Stewart, Tiffany M; Ryan, Donna H; Williamson, Donald A

2011-01-01

Background The primary aims of this article are to describe the utilization of an Internet-based weight management Web site [Healthy Eating, Activity, and Lifestyle Training Headquarters (H.E.A.L.T.H.)] over a 12–27 month period and to describe concurrent weight and fitness changes in Army Reserve soldiers. Methods The H.E.A.L.T.H. Web site was marketed to Army Reserve soldiers via a Web site promotion program for 27 months (phase I) and its continued usage was observed over a subsequent 12-month period (phase II). Web site usage was obtained from the H.E.A.L.T.H. Web site. Weight and fitness data were extracted from the Regional Level Application Software (RLAS). Results A total of 1499 Army Reserve soldiers registered on the H.E.A.L.T.H. Web site. There were 118 soldiers who returned to the H.E.A.L.T.H. Web site more than once. Registration rate reduced significantly following the removal of the Web site promotion program. During phase I, 778 Army Reserve soldiers had longitudinal weight and fitness data in RLAS. Men exceeding the screening table weight gained less weight compared with men below it (p < .007). Percentage change in body weight was inversely associated with change in fitness scores. Conclusions The Web site promotion program resulted in 52% of available Army Reserve soldiers registering onto the H.E.A.L.T.H. Web site, and 7.9% used the Web site more than once. The H.E.A.L.T.H. Web site may be a viable population-based weight and fitness management tool for soldier use. PMID:22027327

Testosterone replacement therapy and the internet: an assessment of providers' health-related web site information content.

Oberlin, Daniel T; Masson, Puneet; Brannigan, Robert E

2015-04-01

To compare how providers of testosterone replacement therapy (TRT) in large metropolitan cities promote androgen replacement on their patient-oriented Web sites. TRT provider Web sites were identified using Google search and the terms "Testosterone replacement" and the name of the 5 most populous US cities. These Web sites were assessed for (1) type or specialty of medical provider, (2) discussion of the benefits and risks of TRT, and (3) industry affiliations. In total, 75 Web sites were evaluated. Twenty-seven of the 75 clinics (36%) were directed by nonphysicians, 35 (47%) were overseen by nonurology or nonendocrine physicians, and only 13 (17%) were specialist managed. Fourteen of 75 (18.6%) Web sites disclosed industry relationships. Ninety-five percent of Web sites promoted the benefits of TRT including improved sex drive, cognitive improvement, increased muscle strength, and/or improved energy. Only 20 of 75 Web sites (26.6%) described any side effect of TRT. Web sites directed by specialists were twice as likely to discuss risks of TRT compared with nonspecialist providers (41% vs 20%; odds ratio = 2.77; P <.01). Nine of 75 (12%) of all Web sites actually refuted that TRT was associated with significant side effects. Urologists and endocrinologists are in the minority of providers promoting TRT on the Internet. Specialists are more likely to discuss risks associated with TRT although the majority of surveyed Web sites that promote TRT do not mention treatment risks. There is substantial variability in quality and quantity of information on provider Web sites, which may contribute to misinformation regarding this prevalent health issue.

Web accessibility and open source software.

PubMed

Obrenović, Zeljko

2009-07-01

A Web browser provides a uniform user interface to different types of information. Making this interface universally accessible and more interactive is a long-term goal still far from being achieved. Universally accessible browsers require novel interaction modalities and additional functionalities, for which existing browsers tend to provide only partial solutions. Although functionality for Web accessibility can be found as open source and free software components, their reuse and integration is complex because they were developed in diverse implementation environments, following standards and conventions incompatible with the Web. To address these problems, we have started several activities that aim at exploiting the potential of open-source software for Web accessibility. The first of these activities is the development of Adaptable Multi-Interface COmmunicator (AMICO):WEB, an infrastructure that facilitates efficient reuse and integration of open source software components into the Web environment. The main contribution of AMICO:WEB is in enabling the syntactic and semantic interoperability between Web extension mechanisms and a variety of integration mechanisms used by open source and free software components. Its design is based on our experiences in solving practical problems where we have used open source components to improve accessibility of rich media Web applications. The second of our activities involves improving education, where we have used our platform to teach students how to build advanced accessibility solutions from diverse open-source software. We are also partially involved in the recently started Eclipse projects called Accessibility Tools Framework (ACTF), the aim of which is development of extensible infrastructure, upon which developers can build a variety of utilities that help to evaluate and enhance the accessibility of applications and content for people with disabilities. In this article we briefly report on these activities.

The design and implementation of web mining in web sites security

NASA Astrophysics Data System (ADS)

Li, Jian; Zhang, Guo-Yin; Gu, Guo-Chang; Li, Jian-Li

2003-06-01

The backdoor or information leak of Web servers can be detected by using Web Mining techniques on some abnormal Web log and Web application log data. The security of Web servers can be enhanced and the damage of illegal access can be avoided. Firstly, the system for discovering the patterns of information leakages in CGI scripts from Web log data was proposed. Secondly, those patterns for system administrators to modify their codes and enhance their Web site security were provided. The following aspects were described: one is to combine web application log with web log to extract more information, so web data mining could be used to mine web log for discovering the information that firewall and Information Detection System cannot find. Another approach is to propose an operation module of web site to enhance Web site security. In cluster server session, Density-Based Clustering technique is used to reduce resource cost and obtain better efficiency.

A state budget shortfall defunded 10 local tobacco coalitions during a randomized trial but defunded coalitions continued to have access to 2 technical assistance Web sites. To test the ability of Web-based technology to provide technical assistance to local tobacco control coalitions. Randomized 2-group trial with local tobacco control coalitions as the unit of randomization. Local communities (ie, counties) within the State of Colorado. Leaders and members in 34 local tobacco control coalitions funded by the state health department in Colorado. Two technical assistance Web sites: A Basic Web site with text-based information and a multimedia Enhanced Web site containing learning modules, resources, and communication features. Use of the Web sites in minutes, pages, and session and evaluations of coalition functioning on coalition development, conflict resolution, leadership satisfaction, decision-making satisfaction, shared mission, personal involvement, and organization involvement in survey of leaders and members. Coalitions that were defunded but had access to the multimedia Enhanced Web site during the Fully Funded period and after defunding continued to use it (treatment group × funding status × period, F(3,714) = 3.18, P = .0234). Coalitions with access to the Basic Web site had low Web site use throughout and use by defunded coalitions was nearly zero when funding ceased. Members in defunded Basic Web site coalitions reported that their coalitions functioned worse than defunded Enhanced Web site coalitions (coalition development: group × status, F(1,360) = 4.81, P = .029; conflict resolution: group × status, F(1,306) = 5.69, P = .018; leadership satisfaction: group × status, F(1,342) = 5.69, P = .023). The Enhanced Web site may have had a protective effect on defunded coalitions. Defunded coalitions may have increased their capacity by using the Enhanced Web site when fully funded or by continuing to use the available online resources after defunding. Web-based technical assistance with online training and resources may be a good investment when future funding is not ensured.

Publicly available hospital comparison web sites: determination of useful, valid, and appropriate information for comparing surgical quality.

PubMed

Leonardi, Michael J; McGory, Marcia L; Ko, Clifford Y

2007-09-01

To explore hospital comparison Web sites for general surgery based on: (1) a systematic Internet search, (2) Web site quality evaluation, and (3) exploration of possible areas of improvement. A systematic Internet search was performed to identify hospital quality comparison Web sites in September 2006. Publicly available Web sites were rated on accessibility, data/statistical transparency, appropriateness, and timeliness. A sample search was performed to determine ranking consistency. Six national hospital comparison Web sites were identified: 1 government (Hospital Compare [Centers for Medicare and Medicaid Services]), 2 nonprofit (Quality Check [Joint Commission on Accreditation of Healthcare Organizations] and Hospital Quality and Safety Survey Results [Leapfrog Group]), and 3 proprietary sites (names withheld). For accessibility and data transparency, the government and nonprofit Web sites were best. For appropriateness, the proprietary Web sites were best, comparing multiple surgical procedures using a combination of process, structure, and outcome measures. However, none of these sites explicitly defined terms such as complications. Two proprietary sites allowed patients to choose ranking criteria. Most data on these sites were 2 years old or older. A sample search of 3 surgical procedures at 4 hospitals demonstrated significant inconsistencies. Patients undergoing surgery are increasingly using the Internet to compare hospital quality. However, a review of available hospital comparison Web sites shows suboptimal measures of quality and inconsistent results. This may be partially because of a lack of complete and timely data. Surgeons should be involved with quality comparison Web sites to ensure appropriate methods and criteria.

STRUCTURE AND DYNAMICS OF THE 2012 NOVEMBER 13/14 ECLIPSE WHITE-LIGHT CORONA

DOE Office of Scientific and Technical Information (OSTI.GOV)

Pasachoff, J. M.; Rušin, V.; Saniga, M.

2015-02-20

Continuing our series of observations of coronal motion and dynamics over the solar-activity cycle, we observed from sites in Queensland, Australia, during the 2012 November 13 (UT)/14 (local time) total solar eclipse. The corona took the low-ellipticity shape typical of solar maximum (flattening index ε = 0.01), a change from the composite coronal images we observed and analyzed in this journal and elsewhere for the 2006 and 2008-2010 eclipses. After crossing the northeast Australian coast, the path of totality was over the ocean, so further totality was seen only by shipborne observers. Our results include velocities of a coronal massmore » ejection (CME; during the 36 minutes of passage from the Queensland coast to a ship north of New Zealand, we measured 413 km s{sup –1}) and we analyze its dynamics. We discuss the shapes and positions of several types of coronal features seen on our higher-resolution composite Queensland coronal images, including many helmet streamers, very faint bright and dark loops at the bases of helmet streamers, voids, and radially oriented thin streamers. We compare our eclipse observations with models of the magnetic field, confirming the validity of the predictions, and relate the eclipse phenomenology seen with the near-simultaneous images from NASA's Solar Dynamics Observatory (SDO/AIA), NASA's Extreme Ultraviolet Imager on Solar Terrestrial Relations Observatory, ESA/Royal Observatory of Belgium's Sun Watcher with Active Pixels and Image Processing (SWAP) on PROBA2, and Naval Research Laboratory's Large Angle and Spectrometric Coronagraph Experiment on ESA's Solar and Heliospheric Observatory. For example, the southeastern CME is related to the solar flare whose origin we trace with a SWAP series of images.« less

Bradstreet, D. H.; Steelman, D. P.; Sanders, S. J.; Hargis, J. R.

2004-05-01

In conjunction with the upcoming release of \\it Binary Maker 3.0, an extensive on-line database of eclipsing binaries is being made available. The purposes of the atlas are: \\begin {enumerate} Allow quick and easy access to information on published eclipsing binaries. Amass a consistent database of light and radial velocity curve solutions to aid in solving new systems. Provide invaluable querying capabilities on all of the parameters of the systems so that informative research can be quickly accomplished on a multitude of published results. Aid observers in establishing new observing programs based upon stars needing new light and/or radial velocity curves. Encourage workers to submit their published results so that others may have easy access to their work. Provide a vast but easily accessible storehouse of information on eclipsing binaries to accelerate the process of understanding analysis techniques and current work in the field. \\end {enumerate} The database will eventually consist of all published eclipsing binaries with light curve solutions. The following information and data will be supplied whenever available for each binary: original light curves in all bandpasses, original radial velocity observations, light curve parameters, RA and Dec, V-magnitudes, spectral types, color indices, periods, binary type, 3D representation of the system near quadrature, plots of the original light curves and synthetic models, plots of the radial velocity observations with theoretical models, and \\it Binary Maker 3.0 data files (parameter, light curve, radial velocity). The pertinent references for each star are also given with hyperlinks directly to the papers via the NASA Abstract website for downloading, if available. In addition the Atlas has extensive searching options so that workers can specifically search for binaries with specific characteristics. The website has more than 150 systems already uploaded. The URL for the site is http://ebola.eastern.edu/.

The Atlas of Chinese World Wide Web Ecosystem Shaped by the Collective Attention Flows.

Lou, Xiaodan; Li, Yong; Gu, Weiwei; Zhang, Jiang

2016-01-01

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

2008-01-01

This catalog is a supplement to the "Five Millennium Canon of Solar Eclipses." It includes additional information for each eclipse that could not be included in the original 648-page publication because of size limits. The data tabulated for each eclipse include the catalog number, canon plate number, calendar date, Terrestrial Dynamical Time of greatest eclipse, (Delta)T, lunation number, Saros number, eclipse type, Quincena Lunar Eclipse parameter, gamma, eclipse magnitude, geographic coordinates of greatest eclipse (latitude and longitude), and the circumstances at greatest eclipse (i.e., Sun altitude and azimuth, path width, and central line duration). The Canon and the Catalog both use the same solar and lunar ephemerides as well as the same values of (Delta)T. This 1-to-1 correspondence between them will enhance the value of each. The researcher may now search, evaluate, and compare eclipses graphically (Canon) or textually (Catalog).

Written and video approaches to donor education have been shown to enhance donation attitudes and intentions to give blood, particularly when the information provides specific coping suggestions for donation-related concerns. This study extends this work by comparing Web-based approaches to donor preparation among donors and nondonors. Young adults (62% female; mean [±SD] age, 19.3 [±1.5] years; mean [range] number of prior blood donations, 1.1 [0-26]; 60% nondonors) were randomly assigned to view 1) a study Web site designed to address common blood donor concerns and suggest specific coping strategies (n = 238), 2) a standard blood center Web site (n = 233), or 3) a control Web site where participants viewed videos of their choice (n = 202). Measures of donation attitude, anxiety, confidence, intention, anticipated regret, and moral norm were completed before and after the intervention. Among nondonors, the study Web site produced greater changes in donation attitude, confidence, intention, and anticipated regret relative to both the standard and the control Web sites, but only differed significantly from the control Web site for moral norm and anxiety. Among donors, the study Web site produced greater changes in donation confidence and anticipated regret relative to both the standard and the control Web sites, but only differed significantly from the control Web site for donation attitude, anxiety, intention, and moral norm. Web-based donor preparation materials may provide a cost-effective way to enhance donation intentions and encourage donation behavior. © 2012 American Association of Blood Banks.

Astronomers Without Borders: An IYA2009 Organization Node Dedicated to Connecting Groups Worldwide

NASA Astrophysics Data System (ADS)

Simmons, Michael

2008-05-01

Astronomers Without Borders (AWB) is a new global organizational and IYA2009 Organizational Node dedicated to furthering understanding and goodwill across national and cultural boundaries using the universal appeal of astronomy, a common language spoken by all those who share an interest in the sky. It is a universal interest that connects us. The AWB network of Affiliates will bring together up to 1000 astronomy clubs, magazines and other organizations involved in astronomy. Regional Coordinators work within their own regions - based on common language and culture rather than political or geographic boundaries - to best implement AWB's goals, involve the region's participants and bring in new ideas based on local culture and tradition. Participation is free for all Affiliates. The AWB web site is the center for the network of Affiliates. This Community Center is the global meeting place where Affiliates interact. Forums, galleries and more interactive technologies will be used. Sharing Telescopes and Resources (STAR) gathers both surplus and new telescopes and other equipment in developed countries and donates them to clubs in undeveloped countries. Follow-up programs are meant to ensure the best and widest use of the telescope in the destination country, and to maintain a relationship between donors and recipients. The World at Night (TWAN) has been designated as a Special IYA2009 Project. TWAN's specialty photographers create wide-angle images of the night sky in important natural and historic settings around the world that dramatically demonstrate the universal nature and appeal of the night sky. A web site, major exhibitions and more are planned for IYA2009. Astro-tourism has been proposed by several Affiliates. This program will draw on existing facilities and experiences, primarily from the long-established solar eclipse tour industry. AWB is meant to continue and grow for many years beyond the end of IYA2009.

2006-01-01

During 5,000-year period from -1999 to +3000 (2000BCE to 3000CE), Earth will experience 11,898 eclipses of the Sun. The statistical distribution of eclipse types for this interval is as follows: 4,200 partial eclipses, 3956 annular eclipses, 3173 total eclipses,and 569 hybrid eclipses. Detailed global maps for each of the 11,898 eclipses delineate the geographic regions of visibility for both the penumbral (partial) and umbral or antumbral (total, annular, or hybrid) phases of every event. Modern political borders are plotted to assist in the determination of eclipse visibility. The uncertainty in Earth's rotational period expressed in the parameter (delta)T and its impact on the geographic visibility of eclipses in the past and future is discussed.

2017-12-24

The purpose of this study was to survey the accessibility and quality of prostate-specific antigen (PSA) screening information from National Cancer Institute (NCI) cancer center and public health organization Web sites. We surveyed the December 1, 2016, version of all 63 NCI-designated cancer center public Web sites and 5 major online clearinghouses from allied public/private organizations (cancer.gov, cancer.org, PCF.org, USPSTF.org, and CDC.gov). Web sites were analyzed according to a 50-item list of validated health care information quality measures. Web sites were graded by 2 blinded reviewers. Interrater agreement was confirmed by Cohen kappa coefficient. Ninety percent of Web sites addressed PSA screening. Cancer center sites covered 45% of topics surveyed, whereas organization Web sites addressed 70%. All organizational Web pages addressed the possibility of false-positive screening results; 41% of cancer center Web pages did not. Forty percent of cancer center Web pages also did not discuss next steps if a PSA test was positive. Only 6% of cancer center Web pages were rated by our reviewers as "superior" (eg, addressing >75% of the surveyed topics) versus 20% of organizational Web pages. Interrater agreement between our reviewers was high (kappa coefficient = 0.602). NCI-designated cancer center Web sites publish lower quality public information about PSA screening than sites run by major allied organizations. Nonetheless, information and communication deficiencies were observed across all surveyed sites. In an age of increasing patient consumerism, prospective prostate cancer patients would benefit from improved online PSA screening information from provider and advocacy organizations. Validated cancer patient Web educational standards remain an important, understudied priority. Copyright © 2018. Published by Elsevier Inc.

Tobacco-prevention messages online: social marketing via the Web.

PubMed

Lin, Carolyn A; Hullman, Gwen A

2005-01-01

Antitobacco groups have joined millions of other commercial or noncommercial entities in developing a presence on the Web. These groups primarily represent the following different sponsorship categories: grassroots, medical, government, and corporate. To obtain a better understanding of the strengths and weaknesses in the message design of antitobacco Web sites, this project analyzed 100 antitobacco Web sites ranging across these four sponsorship categories. The results show that the tobacco industry sites posted just enough antismoking information to appease the antismoking publics. Medical organizations designed their Web sites as specialty sites and offered mostly scientific information. While the government sites resembled a clearinghouse for antitobacco related information, the grassroots sites represented the true advocacy outlets. In general, the industry sites provided the weakest persuasive messages and medical sites fared only slightly better. Government and grassroots sites rated most highly in presenting their antitobacco campaign messages on the Web.

2013-08-01

This article describes testing of a prototype Web site for adolescent mothers with postpartum depression; providing proof of concept. Participants (N=138) were recruited from a public school-based program for adolescent parents and completed the Mental Health Acceptability Scale, Stigma Scale for Receiving Psychological Help, and Attitudes Towards Seeking Professional Psychological Help Scale before, and after, the Web site intervention. They also provided feedback on the usability of the Web site. Attitudes related to depression and treatment (ATSPPH) improved after viewing the Web site (p=.023). Feedback on the Web site indicated that it was easy to use (77%), reflecting highly acceptable score for product usability. The data provide the foundation for the launch of the Web site from prototype to product and more comprehensive testing. The creation and testing of informational text messages will be added to the Web site to increase the interactivity and dose of the intervention. Copyright © 2013 Elsevier Inc. All rights reserved.

Framing medical tourism: an examination of appeal, risk, convalescence, accreditation, and interactivity in medical tourism web sites.

PubMed

Mason, Alicia; Wright, Kevin B

2011-02-01

This exploratory study analyzed the content of medical tourism Web sites in an attempt to examine how they convey information about benefits and risks of medical procedures, how they frame credibility, and the degree to which these Web sites include interactive features for consumers. Drawing upon framing theory, the researchers content analyzed a sample of 66 medical tourism Web sites throughout the world. The results indicated that medical tourism Web sites largely promote the benefits of medical procedures while downplaying the risks, and relatively little information regarding the credibility of these services appears. In addition, the presentation of benefits/risks, credibility, and Web site interactivity were found to differ by region and type of facility. The authors discuss the implications of these findings concerning the framing of medical tourism Web site content, future directions for research, and limitations.

This study aims to assess and compare melanoma information quality in Hungarian, Czech, and German languages on the Internet. We used country-specific Google search engines to retrieve the first 25 uniform resource locators (URLs) by searching the word "melanoma" in the given language. Using the automated toolbar of Health On the Net Foundation (HON), we assessed each Web site for HON certification based on the Health On the Net Foundation Code of Conduct (HONcode). Information quality was determined using a 35-point checklist created by Bichakjian et al. (J Clin Oncol 20:134-141, 2002), with the NCCN melanoma guideline as control. After excluding duplicate and link-only pages, a total of 24 Hungarian, 18 Czech, and 21 German melanoma Web sites were evaluated and rated. The amount of HON certified Web sites was the highest among the German Web pages (19%). One of the retrieved Hungarian and none of the Czech Web sites were HON certified. We found the highest number of Web sites containing comprehensive, correct melanoma information in German language, followed by Czech and Hungarian pages. Although the majority of the Web sites lacked data about incidence, risk factors, prevention, treatment, work-up, and follow-up, at least one comprehensive, high-quality Web site was found in each language. Several Web sites contained incorrect information in each language. While a small amount of comprehensive, quality melanoma-related Web sites was found, most of the retrieved Web content lacked basic disease information, such as risk factors, prevention, and treatment. A significant number of Web sites contained malinformation. In case of melanoma, primary and secondary preventions are of especially high importance; therefore, the improvement of disease information quality available on the Internet is necessary.

Information on infantile colic on the World Wide Web.

PubMed

Bailey, Shana D; D'Auria, Jennifer P; Haushalter, Jamie P

2013-01-01

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

Systematic Review of Quality of Patient Information on Phalloplasty in the Internet.

PubMed

Karamitros, Georgios A; Kitsos, Nikolaos A; Sapountzis, Stamatis

2017-12-01

An increasing number of patients, considering aesthetic surgery, use Internet health information as their first source of information. However, the quality of information available in the Internet on phalloplasty is currently unknown. This study aimed to assess the quality of patient information on phalloplasty available in the Internet. The assessment of the Web sites was based on the modified Ensuring Quality Information for Patients (EQIP) instrument (36 items). Three hundred Web sites were identified by the most popular Web search engines. Ninety Web sites were assessed after, duplicates, irrelevant sources and Web sites in other languages rather than English were excluded. Only 16 (18%) Web sites addressed >21 items, and scores tended to be higher for Web sites developed by academic centers and the industry than for Web sites developed by private practicing surgeons. The EQIP score achieved by Web sites ranged between 4 and 29 of the total 36 points, with a median value of 17.5 points (interquartile range, 13-21). The top 5 Web sites with the highest scores were identified. The quality of patient information on phalloplasty in the Internet is substandard, and the existing Web sites present inadequate information. There is a dire need to improve the quality of Internet phalloplasty resources for potential patients who might consider this procedure. This journal requires that authors assign a level of evidence to each article.

Practicing for 2023 and 2024: What the AAS Solar Eclipse Task Force Learned from the "Great American Eclipse" of 2017

NASA Astrophysics Data System (ADS)

Fienberg, R. T.; Speck, A. K.; Habbal, S. R.

2017-12-01

More than three years ahead of the "Great American Eclipse" of August 2017, the American Astronomical Society formed the AAS Solar Eclipse Task Force to function as a think tank, coordinating body, and communication gateway to the vast resources available about the 2017 eclipse and solar eclipses more generally. The task force included professional and amateur astronomers, formal and informal educators, and science journalists; many had experienced total solar eclipses before, and others would experience their first totality in August 2017. The AAS task force secured funding from the AAS Council, the National Science Foundation, and NASA. These resources were used mainly for three purposes: (1) to build a website that contains basic information about solar eclipses, safe viewing practices, and eclipse imaging and video, along with resources for educators and the media and a searchable map of eclipse-related events and activities, with links to other authoritative websites with more detailed information; (2) to solicit, receive, evaluate, and fund proposals for mini-grants to support eclipse-related education and public outreach to underrepresented groups both inside and outside the path of totality; and (3) to organize a series of multidisciplinary workshops across the country to prepare communities for the eclipse and to facilitate collaborations between astronomers, meteorologists, school administrators, and transporation and emergency-management professionals. Most importantly, the AAS Solar Eclipse Task Force focused on developing and disseminating appropriate eclipse safety information. The AAS and NASA jointly developed safety messaging that won the endorsement of the American Academies of Opthalmology and Optometry. In the weeks immediately preceding the eclipse, it became clear that the marketplace was being flooded by counterfeit eclipse glasses and solar viewers, leading to a last minute change in our communication strategy. In this talk, we'll review the task force's activities, take stock of what went right and what went wrong, and consider how to do an even better job preparing the nation for the next two "Great American" solar eclipses: the annular eclipse of October 14, 2023, and the total eclipse of April 8, 2024.

Prospective analysis of the quality of Spanish health information web sites after 3 years.

PubMed

Conesa-Fuentes, Maria C; Hernandez-Morante, Juan J

2016-12-01

Although the Internet has become an essential source of health information, our study conducted 3 years ago provided evidence of the low quality of Spanish health web sites. The objective of the present study was to evaluate the quality of Spanish health information web sites now, and to compare these results with those obtained 3 years ago. For the original study, the most visited health information web sites were selected through the PageRank® (Google®) system. The present study evaluated the quality of the same web sites from February to May 2013, using the method developed by Bermúdez-Tamayo et al. and HONCode® criteria. The mean quality of the selected web sites was low and has deteriorated since the previous evaluation, especially in regional health services and institutions' web sites. The quality of private web sites remained broadly similar. Compliance with privacy and update criteria also improved in the intervening period. The results indicate that, even in the case of health web sites, design or appearance is more relevant to developers than quality of information. It is recommended that responsible institutions should increase their efforts to eliminate low-quality health information that may further contribute to health problems.

The quality of mental health information commonly searched for on the Internet.

PubMed

Grohol, John M; Slimowicz, Joseph; Granda, Rebecca

2014-04-01

Previous research has reviewed the quality of online information related to specific mental disorders. Yet, no comprehensive study has been conducted on the overall quality of mental health information searched for online. This study examined the first 20 search results of two popular search engines-Google and Bing-for 11 common mental health terms. They were analyzed using the DISCERN instrument, an adaptation of the Depression Website Content Checklist (ADWCC), Flesch Reading Ease and Flesch-Kincaid Grade Level readability measures, HONCode badge display, and commercial status, resulting in an analysis of 440 web pages. Quality of Web site results varied based on type of disorder examined, with higher quality Web sites found for schizophrenia, bipolar disorder, and dysthymia, and lower quality ratings for phobia, anxiety, and panic disorder Web sites. Of the total Web sites analyzed, 67.5% had good or better quality content. Nearly one-third of the search results produced Web sites from three entities: WebMD, Wikipedia, and the Mayo Clinic. The mean Flesch Reading Ease score was 41.21, and the mean Flesch-Kincaid Grade Level score was 11.68. The presence of the HONCode badge and noncommercial status was found to have a small correlation with Web site quality, and Web sites displaying the HONCode badge and commercial sites had lower readability scores. Popular search engines appear to offer generally reliable results pointing to mostly good or better quality mental health Web sites. However, additional work is needed to make these sites more readable.

Accredited hand surgery fellowship Web sites: analysis of content and accessibility.

PubMed

Trehan, Samir K; Morrell, Nathan T; Akelman, Edward

2015-04-01

To assess the accessibility and content of accredited hand surgery fellowship Web sites. A list of all accredited hand surgery fellowships was obtained from the online database of the American Society for Surgery of the Hand (ASSH). Fellowship program information on the ASSH Web site was recorded. All fellowship program Web sites were located via Google search. Fellowship program Web sites were analyzed for accessibility and content in 3 domains: program overview, application information/recruitment, and education. At the time of this study, there were 81 accredited hand surgery fellowships with 169 available positions. Thirty of 81 programs (37%) had a functional link on the ASSH online hand surgery fellowship directory; however, Google search identified 78 Web sites. Three programs did not have a Web site. Analysis of content revealed that most Web sites contained contact information, whereas information regarding the anticipated clinical, research, and educational experiences during fellowship was less often present. Furthermore, information regarding past and present fellows, salary, application process/requirements, call responsibilities, and case volume was frequently lacking. Overall, 52 of 81 programs (64%) had the minimal online information required for residents to independently complete the fellowship application process. Hand fellowship program Web sites could be accessed either via the ASSH online directory or Google search, except for 3 programs that did not have Web sites. Although most fellowship program Web sites contained contact information, other content such as application information/recruitment and education, was less frequently present. This study provides comparative data regarding the clinical and educational experiences outlined on hand fellowship program Web sites that are of relevance to residents, fellows, and academic hand surgeons. This study also draws attention to various ways in which the hand surgery fellowship application process can be made more user-friendly and efficient.

Public transparency Web sites for radiology practices: prevalence of price, clinical quality, and service quality information.

PubMed

Rosenkrantz, Andrew B; Doshi, Ankur M

2016-01-01

To assess information regarding radiology practices on public transparency Web sites. Eight Web sites comparing radiology centers' price and quality were identified. Web site content was assessed. Six of eight Web sites reported examination prices. Other reported information included hours of operation (4/8), patient satisfaction (2/8), American College of Radiology (ACR) accreditation (3/8), on-site radiologists (2/8), as well as parking, accessibility, waiting area amenities, same/next-day reports, mammography follow-up rates, examination appropriateness, radiation dose, fellowship-trained radiologists, and advanced technologies (1/8 each). Transparency Web sites had a preponderance of price (and to a lesser extent service quality) information, risking fostering price-based competition at the expense of clinical quality.

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.

Food marketing on popular children's web sites: a content analysis.

PubMed

Alvy, Lisa M; Calvert, Sandra L

2008-04-01

In 2006 the Institute of Medicine (IOM) concluded that food marketing was a contributor to childhood obesity in the United States. One recommendation of the IOM committee was for research on newer marketing venues, such as Internet Web sites. The purpose of this cross-sectional study was to answer the IOM's call by examining food marketing on popular children's Web sites. Ten Web sites were selected based on market research conducted by KidSay, which identified favorite sites of children aged 8 to 11 years during February 2005. Using a standardized coding form, these sites were examined page by page for the existence, type, and features of food marketing. Web sites were compared using chi2 analyses. Although food marketing was not pervasive on the majority of the sites, seven of the 10 Web sites contained food marketing. The products marketed were primarily candy, cereal, quick serve restaurants, and snacks. Candystand.com, a food product site, contained a significantly greater amount of food marketing than the other popular children's Web sites. Because the foods marketed to children are not consistent with a healthful diet, nutrition professionals should consider joining advocacy groups to pressure industry to reduce online food marketing directed at youth.

One Course, One Web Site--Of Course? Maybe Not!

ERIC Educational Resources Information Center

Cohn, Ellen R.

2004-01-01

Colleges and universities increasingly employ commercial Web-based course management systems (such as Blackboard and WebCT). How is it, then, that these institutions unquestioningly allocate a unique Web site to each class? Why establish one Web site for one course when other options provide so many benefits? Why isn't there a clamor for…

Integrating NASA Dryden Research Endeavors into the Teaching-Learning of Mathematics in the K-12 Classroom via the WWW

NASA Technical Reports Server (NTRS)

Ward, Robin A.

2002-01-01

The primary goal of this project was to continue populating the currently existing web site developed in 1998 in conjunction with the NASA Dryden Flight Research Center and California Polytechnic State University, with more mathematics lesson plans and activities that K-12 teachers, students, home-schoolers, and parents could access. All of the activities, while demonstrating some mathematical topic, also showcase the research endeavors of the NASA Dryden Flight Research Center. The website is located at: http://daniel.calpoly.edu/dfrc/Robin. The secondary goal of this project was to share the web-based activities with educators at various conferences and workshops. To address the primary goal of this project, over the past year, several new activities were posted on the web site and some of the existing activities were enhanced to contain more video clips, photos, and materials for teachers. To address the project's secondary goal, the web-based activities were showcased at several conferences and workshops. Additionally, in order to measure and assess the outreach impact of the web site, a link to the web site hitbox.com was established in April 2001, which allowed for the collection of traffic statistics against the web site (such as the domains of visitors, the frequency of visitors to this web site, etc.) Provided is a description of some of the newly created activities posted on the web site during the project period of 2001-2002, followed by a description of the conferences and workshops at which some of the web-based activities were showcased. Next is a brief summary of the web site's traffic statistics demonstrating its worldwide educational impact, followed by a listing of some of the awards and accolades the web site has received.

Report of the IAU Working Group on Solar Eclipses

Pasachoff, Jay M.

2015-08-01

The Working Group on Solar Eclipses coordinates scientists and information in the study of the Sun and the heliosphere at solar eclipses. Our Website at http://eclipses.info has a wide variety of information, including links to maps and other websites dealing with solar eclipses, as well as information on how to observe the partial-phases of solar eclipses safely and why it is interesting for not only scientists but also for the public to observe eclipses and to see how we work to uncover the mysteries of the sun's upper atmosphere. In the last triennium, there were total eclipses in Australia and the Pacific in 2012; in an arc across Africa from Gabon to Uganda and Kenya in 2013; and in the Arctic, including Svalbard and the Faeroes plus many airplanes aloft, in 2015. In the coming triennium, there will be total solar eclipses in Indonesia and the Pacific in 2016 and then, on 21 August 2017, a total solar eclipse that will sweep across the Continental United States from northwest to southeast. Mapping websites, all linked to http://eclipses.info, include Fred Espenak's http://EclipseWise.com; Michael Zeiler's http://GreatAmericanEclipse.com and http://eclipse-maps.com; Xavier Jubier's http://xjubier.free.fr; and (with weather and cloudiness analysis) Jay Anderson's http://eclipser.ca. Members of the Working Group, chaired by Jay Pasachoff (U.S.), include Iraida Kim (Russia), Kiroki Kurokawa (Japan), Jagdev Singh (India), Vojtech Rusin (Slovakia), Zhongquan Qu (China), Fred Espenak (U.S.), Jay Anderson (Canada), Glenn Schneider (U.S.), Michael Gill (U.K.), Xavier Jubier (France), Michael Zeiler (U.S.), and Bill Kramer (U.S.).

Mapping the 2017 Eclipse: Education, Navigation, Inspiration

NASA Astrophysics Data System (ADS)

Zeiler, M.

2015-12-01

Eclipse maps are a unique vessel of knowledge. At a glance, they communicate the essential knowledge of where and when to successfully view a total eclipse of the sun. An eclipse map also provides detailed knowledge of eclipse circumstances superimposed on the highway system for optimal navigation, especially in the event that weather forces relocation. Eclipse maps are also a vital planning tool for solar physicists and astrophotographers capturing high-resolution imagery of the solar corona. Michael Zeiler will speak to the role of eclipse maps in educating the American public and inspiring people to make the effort to reach the path of totality for the sight of a lifetime. Michael will review the role of eclipse maps in astronomical research and discuss a project under development, the 2017 Eclipse Atlas for smartphones, tablets, and desktop computers.

DISTANT EARLY WARNING SYSTEM for Tsunamis - A wide-area and multi-hazard approach

NASA Astrophysics Data System (ADS)

Hammitzsch, Martin; Lendholt, Matthias; Wächter, Joachim

2010-05-01

The DEWS (Distant Early Warning System) [1] project, funded under the 6th Framework Programme of the European Union, has the objective to create a new generation of interoperable early warning systems based on an open sensor platform. This platform integrates OGC [2] SWE [3] compliant sensor systems for the rapid detection of hazardous events, like earthquakes, sea level anomalies, ocean floor occurrences, and ground displacements in the case of tsunami early warning. Based on the upstream information flow DEWS focuses on the improvement of downstream capacities of warning centres especially by improving information logistics for effective and targeted warning message aggregation for a multilingual environment. Multiple telecommunication channels will be used for the dissemination of warning messages. Wherever possible, existing standards have been integrated. The Command and Control User Interface (CCUI), a rich client application based on Eclipse RCP (Rich Client Platform) [4] and the open source GIS uDig [5], integrates various OGC services. Using WMS (Web Map Service) [6] and WFS (Web Feature Service) [7] spatial data are utilized to depict the situation picture and to integrate a simulation system via WPS (Web Processing Service) [8] to identify affected areas. Warning messages are compiled and transmitted in the OASIS [9] CAP (Common Alerting Protocol) [10] standard together with addressing information defined via EDXL-DE (Emergency Data Exchange Language - Distribution Element) [11]. Internal interfaces are realized with SOAP [12] web services. Based on results of GITEWS [13] - in particular the GITEWS Tsunami Service Bus [14] - the DEWS approach provides an implementation for tsunami early warning systems but other geological paradigms are going to follow, e.g. volcanic eruptions or landslides. Therefore in future also multi-hazard functionality is conceivable. The specific software architecture of DEWS makes it possible to dock varying sensors to the system and to extend the CCUI with hazard specific functionality. The presentation covers the DEWS project, the system architecture and the CCUI in conjunction with details of information logistics. The DEWS Wide Area Centre connecting national centres to allow the international communication and warning exchange is presented also.

2005-06-01

Recent attempts to propose criteria for judging the quality of pharmaceutical and healthcare Web sites do not distinguish between attributes of Web site design related to content and other attributes not related to the content. The Elaboration Likelihood Model from persuasion literature is used as a framework for investigating the effects of Web site design on consequents like attitude and knowledge acquisition. A between-subjects, 2 (high or low involvement)x2 (Web site designed with high or low aspects of visual appeal) factorial design was used in this research. College students were randomly assigned to these treatment groups yielding a balanced design with 29 observations per treatment cell. Analysis of variance results for the effects of involvement and Web site design on attitude and knowledge indicated that the interaction between the independent variables was not significant in both analyses. Examination of main effects revealed that participants who viewed the Web site with higher visual appeal actually had slightly lower knowledge scores (6.32) than those who viewed the Web site with lower visual appeal (7.03, F(1,112)=3.827, P=.053). Results of this research seem to indicate that aspects of Web site design (namely aspects of visual appeal and quality) may not play a role in attaining desired promotional objectives, which can include development of favorable attitudes toward the product and facilitating knowledge acquisition.

Evaluation of Quality, Content, and Use of the Web Site Prepared for Family Members Giving Care to Stroke Patients.

Demir, Yasemin; Gozum, Sebahat

2015-09-01

This study was designed to evaluate the quality, content, usability, and efficacy of a Web site prepared for the purpose of improving the caregiving capability of family members who provide care for stroke survivors at home. The DISCERN score for the Web site was found to be 4.35 over 5. The first section that assesses reliability of the Web site was 4.38 over 5; mean score of the second section that measures the quality of the provided information on treatment/care options was 4.30, and mean score of the third section that gives a general evaluation of the material was 4.1. The Web site content achieved an average score of 3.47 over 4 after evaluation by experts. The Web site system usability score was found to be 79.4 over 100. The Web site was utilized mostly for exercises in bed (76.3%; n = 29), use of medications, and patient safety (68.4%; n = 26). It was determined that those who were younger and employed and had no previous experience of nursing any patient utilized relatively more from the section of patient nutrition and oral care and married family caregivers from the body hygiene section. The Web site quality and content were judged to be good and reliable to use. The Web site was efficiently used by caregivers.

National leaders are calling for opportunities to facilitate the Future of Nursing. Opportunities can be encouraged through state nurses association Web sites, which are part of the American Nurses Association, that are well designed, with appropriate content, and in a language professional nurses understand. The American Nurses Association and constituent state nurses associations provide information about nursing practice, ethics, credentialing, and health on Web sites. We conducted usability evaluations to determine compliance with heuristic and ethical principles for Web site design. We purposefully sampled 27 nursing association Web sites and used 68 heuristic and ethical criteria to perform systematic usability assessments of nurse association Web sites. Web site analysis included seven double experts who were all RNs trained in usability analysis. The extent to which heuristic and ethical criteria were met ranged widely from one state that met 0% of the criteria for "help and documentation" to states that met greater than 92% of criteria for "visibility of system status" and "aesthetic and minimalist design." Suggested improvements are simple yet make an impact on a first-time visitor's impression of the Web site. For example, adding internal navigation and tracking features and providing more details about the application process through help and frequently asked question documentation would facilitate better use. Improved usability will improve effectiveness, efficiency, and consumer satisfaction with these Web sites.

Effectiveness of off-line and web-based promotion of health information web sites.

PubMed

Jones, Craig E; Pinnock, Carole B

2002-01-01

The relative effectiveness of off-line and web-based promotional activities in increasing the use of health information web sites by target audiences were compared. Visitor sessions were classified according to their method of arrival at the site (referral) as external web site, search engine, or "no referrer" (i.e., visitor arriving at the site by inputting URL or using bookmarks). The number of Australian visitor sessions correlated with no referrer referrals but not web site or search-engine referrals. Results showed that the targeted consumer group is more likely to access the web site as a result of off-line promotional activities. The properties of target audiences likely to influence the effectiveness of off-line versus on-line promotional strategies include the size of the Internet using population of the target audience, their proficiency in the use of the Internet, and the increase in effectiveness of off-line promotional activities when applied to locally defined target audiences.

Information about liver transplantation on the World Wide Web.

Orthotopic liver transplant (OLTx) has evolved to a successful surgical management for end-stage liver diseases. Awareness and information about OLTx is an important tool in assisting OLTx recipients and people supporting them, including non-transplant clinicians. The study aimed to investigate the nature and quality of liver transplant-related patient information on the World Wide Web. Four common search engines were used to explore the Internet by using the key words 'Liver transplant'. The URL (unique resource locator) of the top 50 returns was chosen as it was judged unlikely that the average user would search beyond the first 50 sites returned by a given search. Each Web site was assessed on the following categories: origin, language, accessibility and extent of the information. A weighted Information Score (IS) was created to assess the quality of clinical and educational value of each Web site and was scored independently by three transplant clinicians. The Internet search performed with the aid of the four search engines yielded a total of 2,255,244 Web sites. Of the 200 possible sites, only 58 Web sites were assessed because of repetition of the same Web sites and non-accessible links. The overall median weighted IS was 22 (IQR 1 - 42). Of the 58 Web sites analysed, 45 (77%) belonged to USA, six (10%) were European, and seven (12%) were from the rest of the world. The median weighted IS of publications originating from Europe and USA was 40 (IQR = 22 - 60) and 23 (IQR = 6 - 38), respectively. Although European Web sites produced a higher weighted IS [40 (IQR = 22 - 60)] as compared with the USA publications [23 (IQR = 6 - 38)], this was not statistically significant (p = 0.07). Web sites belonging to the academic institutions and the professional organizations scored significantly higher with a median weighted IS of 28 (IQR = 16 - 44) and 24(12 - 35), respectively, as compared with the commercial Web sites (median = 6 with IQR of 0 - 14, p = .001). There was an Intraclass Correlation Coefficient (ICC) of 0.89 and an associated 95% CI (0.83, 0.93) for the three observers on the 58 Web sites. The study highlights the need for a significant improvement in the information available on the World Wide Web about OLTx. It concludes that the educational material currently available on the World Wide Web about liver transplant is of poor quality and requires rigorous input from health care professionals. The authors suggest that clinicians should pay more attention to take the necessary steps to improve the standard of information available on their relevant Web sites and must take an active role in helping their patients find Web sites that provide the best and accurate information specifically applicable to the loco-regional circumstances.

Fifty Year Canon of Lunar Eclipses: 1986-2035

NASA Technical Reports Server (NTRS)

Espenak, Fred

1989-01-01

A complete catalog is presented, listing the general circumstances of every lunar eclipse from 1901 through 2100. To compliment this catalog, a set of figures illustrate the basic Moon-shadow geometry and global visibility for every lunar eclipse over the 200 year interval. Focusing in on the next fifty years, 114 detailed diagrams show the Moon's path through Earth's shadow during every eclipse, including contact times at each phase. The accompanying cylindrical projection maps of Earth show regions of hemispheric visibility for all phases. The appendices discuss eclipse geometry, eclipse frequency and recurrence, enlargement of Earth's shadow, crater timings, eclipse brightness and time determination. Finally, a simple FORTRAN program is provided which can be used to predict the occurrence and general characteristics of lunar eclipses. This work is a companion volume to NASA Reference Publication 1178: Fifty Year Canon of Solar Eclipses: 1986-2035.

Outreach to Scientists and to the Public about the Scientific Value of Solar Eclipses

NASA Astrophysics Data System (ADS)

Pasachoff, J.

2017-12-01

The Great American Eclipse of August 21, 2017, provided an unprecedented opportunity for outreach among American audiences on a giant scale in the age of social media. Professonal scientists and other educators, however, were not exempt from ignorance of the remaining scientific value of observing solar eclipses, often mistakenly thinking that space satellites or mountaintop observatories could make artificial eclipses as good as natural ones, which they can't. Further, as Chair of the Working Group on Eclipses of the International Astronomical Union and as a frequent observer of solar eclipses in other countries, I felt an obligation to provide at-least-equal hospitality in our country. Here I discuss our welcome to and interaction with eclipse scientists from Greece, Slovakia, Australia, Bulgaria, Iran, China, and Japan and their participation in the eclipse observations. I describe my own outreach about the still-vital solar-eclipse observations through my August 2017 articles in Nature Astronomy and Scientific American as well as through book reviews in Nature and Phi Beta Kappa's Key Reporter and co-authorship of a Resource Letter on Observing Solar Eclipses in the July issue og the American Journal of Physics. I describe my eclipse-day Academic Minute on National Public Radio via WAMC and on http://365daysofastronomy.org, a website started during the International Year of Astronomy. I discuss my blog post on lecturing to pre-school through elementary-school students for the National Geographic Society's Education Blog. I show my Op-Ed pre-eclipse in the Washington Post. I discuss our eclipse-night broadcast of an eclipse program on PBS's NOVA, and its preparation over many months, back as far and farther than the February 26, 2017, annular solar eclipse observed from Argentinian Patagonia, with images from prior eclipses including 2013 in Gabon and 2015 in Svalbard. My work at the 2017 total solar eclipse was supported in large part with grants from the Committee for Research and Exploration of the National Geographic Society and from the Solar Terrestrial Program of the Division of Atmospheric and Geospace Sciences of the National Science Foundation.

Surfing for scoliosis: the quality of information available on the Internet.

Mathur, Sameer; Shanti, Nael; Brkaric, Mario; Sood, Vivek; Kubeck, Justin; Paulino, Carl; Merola, Andrew A

2005-12-01

A cross section of Web sites accessible to the general public was surveyed. To evaluate the quality and accuracy of information on scoliosis that a patient might access on the Internet. The Internet is a rapidly expanding communications network with an estimated 765 million users worldwide by the year 2005. Medical information is one of the most common sources of inquires on the Web. More than 100 million Americans accessed the Internet for medical information in the year 2000. Undoubtedly, the use of the Internet for patient information needs will continue to expand as Internet access becomes more readily available. This expansion combined with the Internet's poorly regulated format can lead to problems in the quality of information available. Since the Internet operates on a global scale, implementing and enforcing standards have been difficult. The largely uncontrolled information can potentially negatively influence consumer health outcomes. To identify potential sites, five search engines were selected and the word "scoliosis" was entered into each search engine. A total of 50 Web sites were chosen for review. Each Web site was evaluated according to the type of Web site, quality content, and informational accuracy by three board-certified academic orthopedic surgeons, fellowship trained in spinal surgery, who each has been in practice for a minimum of 8 years. Each Web site was categorized as academic, commercial, physician, nonphysician health professional, and unidentified. In addition, each Web site was evaluated according to scoliosis-specific content using a point value system of 32 disease-specific key words pertinent to the care of scoliosis on an ordinal scale. A list of these words is given. Point values were given for the use of key words related to disease summary, classifications, treatment options, and complications. The accuracy of the individual Web site was evaluated by each spine surgeon using a scale of 1 to 4. A score of 1 represents that the examiner agreed with less than 25% of the information while a score of 4 represents greater than 75% agreement. Of the total 50 Web sites evaluated, 44% were academic, 18% were physician based, 16% were commercial, 12% were unidentified, and 10% were nonphysician health professionals. The quality content score (maximum, 32 points) for academic sites was 12.6 +/- 3.8, physician sites 11.3 +/- 4.0, commercial sites 11 +/- 4.2, unidentified 7.6 +/- 3.9, and nonphysician health professional site 7.0 +/- 1.8. The accuracy score (maximum, 12 points) was 6.6 +/- 2.4 for academic sites, 6.3 +/- 3.0 for physician-professional sites, 6.0 +/- 2.7 for unidentified sites, 5.5 +/- 3.8 for nonphysician professional sites, and 5.0 +/- 1.5 for commercial Web sites. The academic Web sites had the highest mean scores in both quality and accuracy content scores. The information about scoliosis on the Internet is of limited quality and poor information value. Although the majority of the Web sites were academic, the content quality and accuracy scores were still poor. The lowest scoring Web sites were the nonphysician professionals and the unidentified sites, which were often message boards. Overall, the highest scoring Web site related to both quality and accuracy of information was www.srs.org. This Web site was designed by the Scoliosis Research Society. The public and the medical communities need to be aware of these existing limitations of the Internet. Based on our review, the physician must assume primary responsibility of educating and counseling their patients.

e-Ana and e-Mia: A Content Analysis of Pro–Eating Disorder Web Sites

PubMed Central

Schenk, Summer; Wilson, Jenny L.; Peebles, Rebecka

2010-01-01

Objectives. The Internet offers Web sites that describe, endorse, and support eating disorders. We examined the features of pro–eating disorder Web sites and the messages to which users may be exposed. Methods. We conducted a systematic content analysis of 180 active Web sites, noting site logistics, site accessories, “thinspiration” material (images and prose intended to inspire weight loss), tips and tricks, recovery, themes, and perceived harm. Results. Practically all (91%) of the Web sites were open to the public, and most (79%) had interactive features. A large majority (84%) offered pro-anorexia content, and 64% provided pro-bulimia content. Few sites focused on eating disorders as a lifestyle choice. Thinspiration material appeared on 85% of the sites, and 83% provided overt suggestions on how to engage in eating-disordered behaviors. Thirty-eight percent of the sites included recovery-oriented information or links. Common themes were success, control, perfection, and solidarity. Conclusions. Pro–eating disorder Web sites present graphic material to encourage, support, and motivate site users to continue their efforts with anorexia and bulimia. Continued monitoring will offer a valuable foundation to build a better understanding of the effects of these sites on their users. PMID:20558807

Conceptual Web Users' Actions Prediction for Ontology-Based Browsing Recommendations

NASA Astrophysics Data System (ADS)

Robal, Tarmo; Kalja, Ahto

The Internet consists of thousands of web sites with different kinds of structures. However, users are browsing the web according to their informational expectations towards the web site searched, having an implicit conceptual model of the domain in their minds. Nevertheless, people tend to repeat themselves and have partially shared conceptual views while surfing the web, finding some areas of web sites more interesting than others. Herein, we take advantage of the latter and provide a model and a study on predicting users' actions based on the web ontology concepts and their relations.

Does your web site draw new patients?

PubMed

Wallin, Wendy S

2009-11-01

The absence of scientific data forces orthodontists to guess at how best to design Internet sites that persuade prospective patients to call for appointments. This study was conducted to identify the Web-site factors that lead prospective patients to make appointments or, conversely, to reject a practice. Ten participants actively looking online for an orthodontist were recruited to participate. They reviewed 64 orthodontic Web sites in their geographic areas and rated their likelihood of calling each practice for an appointment. The sessions were videotaped. Analysis of participant comments, navigation patterns, and ratings suggested 25 distinguishing factors. Statistical analysis showed 10 Web-site characteristics that predict the success of an orthodontic Web site in attracting new patients.

Informational content of official pharmaceutical industry web sites about treatments for erectile dysfunction.

PubMed

Waack, Katherine E; Ernst, Michael E; Graber, Mark A

2004-12-01

In the last 5 years, several treatments have become available for erectile dysfunction (ED). During this same period, consumer use of the Internet for health information has increased rapidly. In traditional direct-to-consumer advertisements, viewers are often referred to a pharmaceutical company Web site for further information. To evaluate the accessibility and informational content of 5 pharmaceutical company Web sites about ED treatments. Using 10 popular search engines and 1 specialized search engine, the accessibility of the official pharmaceutical company-sponsored Web site was determined by searching under brand and generic names. One company also manufactures an ED device; this site was also included. A structured, explicit review of information found on these sites was conducted. Of 110 searches (1 for each treatment, including corresponding generic drug name, using each search engine), 68 yielded the official pharmaceutical company Web site within the first 10 links. Removal of outliers (for both brand and generic name searches) resulted in 68 of 77 searches producing the pharmaceutical company Web site for the brand-name drug in the top 10 links. Although all pharmaceutical company Web sites contained general information on adverse effects and contraindications to use, only 2 sites gave actual percentages. Three sites provided references for their materials or discussed other treatment or drug options, while 4 of the sites contained profound advertising or emotive content. None mentioned cost of the therapy. The information contained on pharmaceutical company Web sites for ED treatments is superficial and aimed primarily at consumers. It is largely promotional and provides only limited information needed to effectively compare treatment options.

Satellite observations of surface temperature during the March 2015 total solar eclipse.

PubMed

Good, Elizabeth

2016-09-28

The behaviour of remotely sensed land surface temperatures (LSTs) from the spinning-enhanced visible and infrared imager (SEVIRI) during the total solar eclipse of 20 March 2015 is analysed over Europe. LST is found to drop by up to several degrees Celcius during the eclipse, with the minimum LST occurring just after the eclipse mid-point (median=+1.5 min). The drop in LST is typically larger than the drop in near-surface air temperatures reported elsewhere, and correlates with solar obscuration (r=-0.47; larger obscuration = larger LST drop), eclipse duration (r=-0.62; longer duration = larger LST drop) and time (r=+0.37; earlier eclipse = larger LST drop). Locally, the LST drop is also correlated with vegetation (up to r=+0.6), with smaller LST drops occurring over more vegetated surfaces. The LSTs at locations near the coast and at higher elevation are also less affected by the eclipse. This study covers the largest area and uses the most observations of eclipse-induced surface temperature drops to date, and is the first full characterization of satellite LST during an eclipse (known to the author). The methods described could be applied to Geostationary Operational Environmental Satellite (GOES) LST data over North America during the August 2017 total solar eclipse.This article is part of the themed issue 'Atmospheric effects of solar eclipses stimulated by the 2015 UK eclipse'. © 2016 The Author(s).

Eclipses and dust formation by WC9 type Wolf-Rayet stars

NASA Astrophysics Data System (ADS)

Williams, P. M.

2014-12-01

Visual photometry of 16 WC8-9 dust-making Wolf-Rayet (WR) stars during 2001-2009 was extracted from the All-Sky Automated Survey All Star Catalogue (ASAS-3) to search for eclipses attributable to extinction by dust formed in clumps in our line of sight. Data for a comparable number of dust-free WC6-9 stars were also examined to help characterize the data set. Frequent eclipses were observed from WR 104, and several from WR 106, extending the 1994-2001 studies by Kato et al., but not supporting their phasing the variations in WR 104 with its `pinwheel' rotation period. Only four other stars showed eclipses, WR 50 (one of the dust-free stars), WR 69, WR 95 and WR 117, and there may have been an eclipse by WR 121, which had shown two eclipses in the past. No dust eclipses were shown by the `historic' eclipsers WR 103 and WR 113. The atmospheric eclipses of the latter were observed but the suggestion by David-Uraz et al. that dust may be partly responsible for these is not supported. Despite its frequent eclipses, there is no evidence in the infrared images of WR 104 for dust made in its eclipses, demonstrating that any dust formed in this process is not a significant contributor to its circumstellar dust cloud and suggesting that the same applies to the other stars showing fewer eclipses.

The purpose of this study was to utilize sentiment analysis to describe online opinions toward vaginal mesh. We hypothesized that sentiment in legal Web sites would be more negative than that in medical and reference Web sites. We generated a list of relevant key words related to vaginal mesh and searched Web sites using the Google search engine. Each unique uniform resource locator (URL) was sorted into 1 of 6 categories: "medical", "legal", "news/media", "patient generated", "reference", or "unrelated". Sentiment of relevant Web sites, the primary outcome, was scored on a scale of -1 to +1, and mean sentiment was compared across all categories using 1-way analysis of variance. Tukey test evaluated differences between category pairs. Google searches of 464 unique key words resulted in 11,405 URLs. Sentiment analysis was performed on 8029 relevant URLs (3472 legal, 1625 "medical", 1774 "reference", 666 "news media", 492 "patient generated"). The mean sentiment for all relevant Web sites was +0.01 ± 0.16; analysis of variance revealed significant differences between categories (P < 0.001). Web sites categorized as "legal" and "news/media" had a slightly negative mean sentiment, whereas those categorized as "medical," "reference," and "patient generated" had slightly positive mean sentiments. Tukey test showed differences between all category pairs except the "medical" versus "reference" in comparison with the largest mean difference (-0.13) seen in the "legal" versus "reference" comparison. Web sites related to vaginal mesh have an overall mean neutral sentiment, and Web sites categorized as "medical," "reference," and "patient generated" have significantly higher sentiment scores than related Web sites in "legal" and "news/media" categories.

Background A significant number of soldiers exceed the maximum allowable weight standards or have body weights approaching the maximum allowable weight standards. This mandates development of scalable approaches to improve compliance with military weight standards. Methods We developed an intervention that included two components: (1) an Internet-based weight management program (Web site) and (2) a promotion program designed to promote and sustain usage of the Web site. The Web site remained online for 37 months, with the Web site promotion program ending after 25 months. Results Soldiers’ demographics were as follows: mean age, 32 years; body mass index (BMI), 28 kg/m2; 31% female; and 58% Caucasian. Civilian demographics were as follows: mean age, 38 years; BMI, 30 kg/m2; 84% female; and 55% Caucasian. Results indicated that 2417 soldiers and 2147 civilians (N = 4564) registered on the Web site. In the first 25 months (phase 1) of the study, new participants enrolled on the Web site at a rate of 88 (soldiers) and 80 (civilians) per month. After the promotion program was removed (phase 2), new participants enrolled at a rate of 18 (soldiers) and 13 (civilians) per month. Utilization of the Web site was associated with self-reported weight loss (p < .0001). Participants who utilized the Web site more frequently lost more weight (p < .0001). Participants reported satisfaction with the Web site. Conclusions The Web site and accompanying promotion program, when implemented at a military base, received satisfactory ratings and benefited a subset of participants in promoting weight loss. This justifies further examination of effectiveness in a randomized trial setting. PMID:21303642

Hand Society and Matching Program Web Sites Provide Poor Access to Information Regarding Hand Surgery Fellowship.

The Internet is a common resource for applicants of hand surgery fellowships, however, the quality and accessibility of fellowship online information is unknown. The objectives of this study were to evaluate the accessibility of hand surgery fellowship Web sites and to assess the quality of information provided via program Web sites. Hand fellowship Web site accessibility was evaluated by reviewing the American Society for Surgery of the Hand (ASSH) on November 16, 2014 and the National Resident Matching Program (NRMP) fellowship directories on February 12, 2015, and performing an independent Google search on November 25, 2014. Accessible Web sites were then assessed for quality of the presented information. A total of 81 programs were identified with the ASSH directory featuring direct links to 32% of program Web sites and the NRMP directory directly linking to 0%. A Google search yielded direct links to 86% of program Web sites. The quality of presented information varied greatly among the 72 accessible Web sites. Program description (100%), fellowship application requirements (97%), program contact email address (85%), and research requirements (75%) were the most commonly presented components of fellowship information. Hand fellowship program Web sites can be accessed from the ASSH directory and, to a lesser extent, the NRMP directory. However, a Google search is the most reliable method to access online fellowship information. Of assessable programs, all featured a program description though the quality of the remaining information was variable. Hand surgery fellowship applicants may face some difficulties when attempting to gather program information online. Future efforts should focus on improving the accessibility and content quality on hand surgery fellowship program Web sites.

Quality of information available over the Internet has been a cause for concern. Our goal was to evaluate the quality of information available on lung cancer in the United States and Japan and assess the differences between the two. We conducted a prospective, observational Web review by searching the word "lung cancer" in Japanese and English, using Google Japan (Google-J), Google United States (Google-U), and Yahoo Japan (Yahoo-J). The first 50 Web sites displayed were evaluated from the ethical perspective and for the validity of the information. The administrator of each Web site was also investigated. Ethical policies were generally well described in the Web sites displayed by Google-U but less well so in the sites displayed by Google-J and Yahoo-J. The differences in the validity of the information available was more striking, in that 80% of the Web sites generated by Google-U described the most appropriate treatment methods, whereas less than 50% of the Web sites displayed by Google-J and Yahoo-J recommended the standard therapy, and more than 10% advertised alternative therapy. Nonprofit organizations and public institutions were the primary Web site administrators in the United States, whereas commercial or personal Web sites were more frequent in Japan. Differences in the quality of information on lung cancer available over the Internet were apparent between Japan and the United States. The reasons for such differences might be tracked to the administrators of the Web sites. Nonprofit organizations and public institutions are the up-and-coming Web site administrators for relaying reliable medical information.

Report about the Solar Eclipse on August 11, 1999

NASA Astrophysics Data System (ADS)

1999-08-01

This webpage provides information about the total eclipse on Wednesday, August 11, 1999, as it was seen by ESO staff, mostly at or near the ESO Headquarters in Garching (Bavaria, Germany). The zone of totality was about 108 km wide and the ESO HQ were located only 8 km south of the line of maximum totality. The duration of the phase of totality was about 2 min 17 sec. The weather was quite troublesome in this geographical area. Heavy clouds moved across the sky during the entire event, but there were also some holes in between. Consequently, sites that were only a few kilometres from each other had very different viewing conditions. Some photos and spectra of the eclipsed Sun are displayed below, with short texts about the circumstances under which they were made. Please note that reproduction of pictures on this webpage is only permitted, if the author is mentioned as source. Information made available before the eclipse is available here.

It begins with some sequences of the first partial phase and the eclipse watchers. Clouds move over and the landscape darkens as the phase of totality approaches. The Sun is again visible at the very moment this phase ends. Some further sequences from the second partial phase follow. Produced by Herbert Zodet. Dire Forecasts The weather predictions in the days before the eclipse were not good for Munich and surroundings. A heavy front with rain and thick clouds that completely covered the sky moved across Bavaria the day before and the meteorologists predicted a 20% chance of seeing anything at all. On August 10, it seemed that the chances were best in France and in the western parts of Germany, and much less close to the Alps. This changed to the opposite during the night before the eclipse. Now the main concern in Munich was a weather front approaching from the west - would it reach this area before the eclipse? The better chances were then further east, nearer the Austrian border. Many people travelled back and forth along the German highways, many of which quickly became heavily congested. Preparations About 500 persons, mostly ESO staff with their families and friends, were present at the ESO HQ in the morning of August 11. Prior to the eclipse, they received information about the various aspects of solar eclipses and about the specific conditions of this one in the auditorium. Protective glasses were handed out and it was the idea that they would then follow the eclipse from outside. In view of the pessimistic weather forecasts, TV sets had been set up in two large rooms, but in the end most chose to watch the eclipse from the terasse in front of the cafeteria and from the area south of the building. Several telescopes were set up among the trees and on the adjoining field (just harvested). Clouds and Holes It was an unusual solar eclipse experience. Heavy clouds were passing by with sudden rainshowers, but fortunately there were also some holes with blue sky in between. While much of the first partial phase was visible through these, some really heavy clouds moved in a few minutes before the total phase, when the light had begun to fade. They drifted slowly - too slowly! - towards the east and the corona was never seen from the ESO HQ site. From here, the view towards the eclipsed Sun only cleared at the very instant of the second "diamond ring" phenomenon. This was beautiful, however, and evidently took most of the photographers by surprise, so very few, if any, photos were made of this memorable moment. Temperature Curve by Benoit Pirenne Temperature Curve on August 11 [JPEG: 646 x 395 pix - 35k] Measured by Benoit Pirenne - see also his meteorological webpage Nevertheless, the entire experience was fantastic - there were all the expected effects, the darkness, the cool air, the wind and the silence. It was very impressive indeed! And it was certainly a unique day in ESO history! Carolyn Collins Petersen from "Sky & Telescope" participated in the conference at ESO in the days before and watched the eclipse from the "Bürgerplatz" in Garching, about 1.5 km south of the ESO HQ. She managed to see part of the totality phase and filed some dramatic reports at the S&T Eclipse Expedition website. They describe very well the feelings of those in this area! Eclipse Photos Several members of the ESO staff went elsewhere and had more luck with the weather, especially at the moment of totality. Below are some of their impressive pictures. Eclipse Photo by Philippe Duhoux First "Diamond Ring" [JPEG: 400 x 292 pix - 34k] [JPEG: 800 x 583 pix - 144k] [JPEG: 2531 x 1846 pix - 1.3M] Eclipse Photo by Philippe Duhoux Totality [JPEG: 400 x 306 pix - 49k] [JPEG: 800 x 612 pix - 262k] [JPEG: 3039 x 1846 pix - 3.6M] Eclipse Photo by Philippe Duhoux Second "Diamond Ring" [JPEG: 400 x 301 pix - 34k] [JPEG: 800 x 601 pix - 163k] [JPEG: 2905 x 2181 pix - 2.0M] The Corona (Philippe Duhoux) "For the observation of the eclipse, I chose a field on a hill offering a wide view towards the western horizon and located about 10 kilometers north west of Garching." "While the partial phase was mostly cloudy, the sky went clear 3 minutes before the totality and remained so for about 15 minutes. Enough to enjoy the event!" "The images were taken on Agfa CT100 colour slide film with an Olympus OM-20 at the focus of a Maksutov telescope (f = 1000 mm, f/D = 10). The exposure times were automatically set by the camera. During the partial phase, I used an off-axis mask of 40 mm diameter with a mylar filter ND = 3.6, which I removed for the diamond rings and the corona." Note in particular the strong, detached protuberances to the right of the rim, particularly noticeable in the last photo. Eclipse Photo by Cyril Cavadore Totality [JPEG: 400 x 360 pix - 45k] [JPEG: 800 x 719 pix - 144k] [JPEG: 908 x 816 pix - 207k] The Corona (Cyril Cavadore) "We (C.Cavadore from ESO and L. Bernasconi and B. Gaillard from Obs. de la Cote d'Azur) took this photo in France at Vouzier (Champagne-Ardennes), between Reims and Nancy. A large blue opening developed in the sky at 10 o'clock and we decided to set up the telescope and the camera at that time. During the partial phase, a lot of clouds passed over, making it hard to focus properly. Nevertheless, 5 min before totality, a deep blue sky opened above us, allowing us to watch it and to take this picture. 5-10 Minutes after the totality, the sky was almost overcast up to the 4th contact". "The image was taken with a 2x2K (14 µm pixels) Thomson "homemade" CCD camera mounted on a CN212 Takahashi (200 mm diameter telescope) with a 1/10.000 neutral filter. The acquisition software set exposure time (2 sec) and took images in a complete automated way, allowing us to observe the eclipse by naked eye or with binoculars. To get as many images as possible during totality, we use binning 2x2 to reduce the readout time to 19 sec. Afterward, one of the best image was flat-fielded and processed with a special algorithm that modelled a fit the continuous component of the corona and then subtracted from the original image. The remaining details were enhanced by unsharp masking and added to the original image. Finally, gaussian histogram equalization was applied". Eclipse Photo by Eddy Pomaroli Second "Diamond Ring" [JPEG: 400 x 438 pix - 129k] [JPEG: 731 x 800 pix - 277k] [JPEG: 1940 x 2123 pix - 2.3M] Diamond Ring at ESO HQ (Eddy Pomaroli) "Despite the clouds, we saw the second "diamond ring" from the ESO HQ. In a sense, we were quite lucky, since the clouds were very heavy during the total phase and we might easily have missed it all!". "I used an old Minolta SRT-101 camera and a teleobjective (450 mm; f/8). The exposure was 1/125 sec on Kodak Elite 100 (pushed to 200 ASA). I had the feeling that the Sun would become visible and had the camera pointed, by good luck in the correct direction, as soon as the cloud moved away". Eclipse Photo by Roland Reiss First Partial Phase [JPEG: 400 x 330 pix - 94k] [JPEG: 800 x 660 pix - 492k] [JPEG: 3000 x 2475 pix - 4.5M] End of First Partial Phase (Roland Reiss) "I observed the eclipse from my home in Garching. The clouds kept moving and this was the last photo I was able to obtain during the first partial phase, before they blocked everything". "The photo is interesting, because it shows two more images of the eclipsed Sun, below the overexposed central part. In one of them, the remaining, narrow crescent is particularly well visible. They are caused by reflections in the camera. I used a Minolta camera and a Fuji colour slide film". Eclipse Spectra Some ESO people went a step further and obtained spectra of the Sun at the time of the eclipse. Eclipse Spectrum by Roland Reiss Coronal Spectrum [JPEG: 400 x 273 pix - 94k] [JPEG: 800 x 546 pix - 492k] [JPEG: 3000 x 2046 pix - 4.5M] Coronal Spectrum (CAOS Group) The Club of Amateurs in Optical Spectroscopy (with Carlos Guirao Sanchez, Gerardo Avila and Jesus Rodriguez) obtained a spectrum of the solar corona from a site in Garching, about 2 km south of the ESO HQ. "This is a plot of the spectrum and the corresponding CCD image that we took during the total eclipse. The main coronal lines are well visible and have been identified in the figure. Note in particular one at 6374 Angstrom that was first ascribed to the mysterious substance "Coronium". We now know that it is emitted by iron atoms that have lost nine electrons (Fe X)". The equipment was: * Telescope: Schmidt Cassegrain F/6.3; Diameter: 250 mm * FIASCO Spectrograph: Fibre: 135 micron core diameter F = 100 mm collimator, f = 80 mm camera; Grating: 1300 gr/mm blazed at 500 nm; SBIG ST8E CCD camera; Exposure time was 20 sec. Eclipse Spectrum by Bob Fosbury Chromospheric Spectrum [JPEG: 120 x 549 pix - 20k] Chromospheric and Coronal Spectra (Bob Fosbury) "The 11 August 1999 total solar eclipse was seen from a small farm complex called Wolfersberg in open fields some 20km ESE of the centre of Munich. It was chosen to be within the 2min band of totality but likely to be relatively unpopulated". "There were intermittent views of the Sun between first and second contact with quite a heavy rainshower which stopped 9min before totality. A large clear patch of sky revealed a perfect view of the Sun just 2min before second contact and it remained clear for at least half an hour after third contact". "The principal project was to photograph the spectrum of the chromosphere during totality using a transmission grating in front of a moderate telephoto lens. The desire to do this was stimulated by a view of the 1976 eclipse in Australia when I held the same grating up to the eclipsed Sun and was thrilled by the view of the emission line spectrum. The trick now was to get the exposure right!". "A sequence of 13 H-alpha images was combined into a looping movie. The exposure times were different, but some attempt has been made to equalise the intensities. The last two frames show the low chromosphere and then the photosphere emerging at 3rd contact. The [FeX] coronal line can be seen on the left in the middle of the sequence. I used a Hasselblad camera and Agfa slide film (RSX II 100)".

Background: A large number of patients who are interested in esthetic surgery actively search the Internet, which represents nowadays the first source of information. However, the quality of information available in the Internet on liposuction is currently unknown. The aim of this study was to assess the quality of patient information on liposuction available in the Internet. Methods: The quantitative and qualitative assessment of Web sites was based on a modified Ensuring Quality Information for Patients tool (36 items). Five hundred Web sites were identified by the most popular web search engines. Results: Two hundred forty-five Web sites were assessed after duplicates and irrelevant sources were excluded. Only 72 (29%) Web sites addressed >16 items, and scores tended to be higher for professional societies, portals, patient groups, health departments, and academic centers than for Web sites developed by physicians, respectively. The Ensuring Quality Information for Patients score achieved by Web sites ranged between 8 and 29 of total 36 points, with a median value of 16 points (interquartile range, 14–18). The top 10 Web sites with the highest scores were identified. Conclusions: The quality of patient information on liposuction available in the Internet is poor, and existing Web sites show substantial shortcomings. There is an urgent need for improvement in offering superior quality information on liposuction for patients intending to undergo this procedure. PMID:27482498

2005-01-01

More and more consumers are searching the Internet for health information. Health Web sites vary in quality, though, and not all consumers are aware of the need to evaluate the information they find on the Web. Nurses and other health providers involved in patient education can evaluate Web sites and suggest quality sites for patients to use. This article describes a project we implemented in 2 public libraries to educate consumers about quality health care and patient safety using Web sites that we had evaluated earlier. Participants (n = 103) completed resources on health care quality, questions patients should ask about their diagnoses and treatment options, changes in Medicare and Medicare options or ways to make their health benefits work for them, and tips to help prevent medical errors. Most consumers were highly satisfied with the Web sites and the information they learned on quality care from these resources. Many participants did not have Internet access at home or work and instead used the library to search the Web. Information about the Web sites used in this project and other sites on quality care can be made available in libraries and community settings and as part of patient education resources in hospitals. The Web provides easy access for consumers to information about patient safety initiatives and health care quality in general.

Public outreach and education during the 2016 total solar eclipse in Palu and Malang

2016-11-01

MAGIC (Ma Chung Galactic Club) of Ma Chung University, Malang, is one of the amateur astronomers club who did public outreach and education during the Total Solar Eclipse March 9, 2016. The motivation for doing this was the bad experience during Total Solar Eclipse 1983. At that time the Indonesian government forbid the people to observe the Total Solar Eclipse in a way to avoid blindness. We try to fix this misunderstanding by educating people the safe way to enjoy the partial and total solar eclipse. MAGIC team was divided into two teams, one team went to Palu and did the solar eclipse related education in six high schools before and during the eclipse. The other team did the observation on Ma Chung University campus, Malang, to accompany people who want to see the partial solar eclipse through filtered telescopes. The sky during the solar eclipse was clear both in Malang and Palu. People were very excited and satisfied with the solar eclipse, and their interest to astronomy is increased.

Building a Playground: General Guidelines for Creating Educational Web Sites for Children

Meloncon, Lisa; Haynes, Erin; Varelmann, Megan; Groh, Lisa

2015-01-01

Purpose Since 2004, the number of children online has increased 18%, compared with a 10% increase in total users. Not only do children represent a growing segment of Internet users, much of what they do online has a specific purpose: education. To help technical communicators create educational Web sites for children, we offer a set of guidelines to direct the design process. Method Nine children participated in a usability test of the CARES Playground, an educational Web site geared toward 7- to 9-year-olds. The site was designed by a group of graduate students in professional writing based on a review of the (admittedly limited) literature dealing with designing Web sites for children. This paper matches common themes from existing literature to the results of the usability tests. Results Since all the information on designing Web sites for children emerged from the literature of designing Web sites for adults, the themes of navigation, appearance, and content are not unfamiliar. However, the interpretation of those common issues for children—as well as the children’s reaction to them—may be surprising. Conclusion Technical communicators need to be conscious and deliberate when designing Web sites for children. To ensure that educational Web sites are able to meet their learning goals, careful consideration of children’s developmental abilities and Web preferences must be considered. We present several guidelines as a starting point, though further research is needed to confirm and expand upon them. PMID:26633909

First results from the Citizen CATE Experiment from August 2017

NASA Astrophysics Data System (ADS)

Penn, Matthew; Citizen CATE Experiment 2017 Team

2018-01-01

The Citizen Continental-America Telescopic Eclipse Experiment deployed 68 identical telescope/detector systems across the path of totality for the August 2017 solar eclipse. The sites were located from Oregon to South Carolina, and while at any one site the solar corona was observed for just 2 minutes, the combined data set reveals evolution of the corona for 93 minutes of time. CATE aims to measure the acceleration of the fast solar wind in polar plumes, which is currently unknown as the inner solar corona is not observed from space and difficult to observe at high signal to noise from the ground. With radial velocities ranging from 1 to 100 km/s, density enhancements in the wind in the polar plumes should be observed to move across the CATE field of view in about 1 hour.On 21 Aug 2017, the CATE network had fantastic luck, collecting data from more than 56 of the 68 sites, and excellent data was collected at the first and last sites, maximizing the time coverage. Several of the volunteers from 27 universities, 22 high schools and 19 amateur astronomers uploaded one high-dynamic range image on eclipse day and an initial movie of the coronal evolution has been made (https://citizencate.org ). Polar plumes are observed in the CATE data to the edge of the field above both north and south polar coronal holes. Slow evolution of low-lying coronal loops is seen, and large-scale motions are visible in a coronal streamer on the south-east solar limb. An ejection event is observed in the southern coronal hole, but with just 1% of the data analyzed so far, the signal to noise ratio is currently not sufficient to track steady solar wind flows.CATE was funded with a collaboration of federal, corporate and private groups. CATE training was funded by NASA, and CATE equipment was funded by Daystar, Mathworks, Celestron, colorMaker, NSF and a dozen smaller donors. The funding was organized so that all 68 CATE groups are keeping their equipment, and CATE is now seeking other types of citizen science projects in astronomy.

Dornan, Barbara A; Oermann, Marilyn H

2006-01-01

To evaluate the quality of Web sites on breastfeeding for patient education. Descriptive study of 30 Web sites on breastfeeding for patient education, evaluated based on the Health Information Technology Institute (HITI) criteria, readability, and eight content criteria from the American Academy of Pediatrics (AAP) policy statement on breastfeeding. The mean Flesch-Kincaid Grade Level for readability of the 30 sites was 9.2. Seven of the sites included all eight of the content criteria from the AAP, and three sites did not include any of the information recommended by the AAP content criteria. Nurses should be able to recommend best patient education materials for their patients. The five best Web sites for breastfeeding education are identified for patient teaching, and the HITI criteria are explained for nurses to learn how to evaluate Web sites for themselves and their patients.

The X-ray eclipse of the LMC binary CAL 87

NASA Technical Reports Server (NTRS)

Schmidtke, P. C.; Mcgrath, T. K.; Cowley, A. P.; Frattare, L. M.

1993-01-01

ROSAT-PSPC observations of the LMC eclipsing binary CAL 87 show a short-duration, shallow X-ray eclipse which coincides in phase with the primary optical minimum. Characteristics of the eclipse suggest the X-ray emitting region is only partially occulted. Similarities with the eclipse of the accretion-disk corona in X 1822-37 are discussed. However, no temperature variation through eclipse is found for CAL 87. A revised orbital period, combining published data and recent optical photometry, is given.

Kepler eclipsing binary stars. IV. Precise eclipse times for close binaries and identification of candidate three-body systems

DOE Office of Scientific and Technical Information (OSTI.GOV)

Conroy, Kyle E.; Stassun, Keivan G.; Prša, Andrej

2014-02-01

We present a catalog of precise eclipse times and analysis of third-body signals among 1279 close binaries in the latest Kepler Eclipsing Binary Catalog. For these short-period binaries, Kepler's 30 minute exposure time causes significant smearing of light curves. In addition, common astrophysical phenomena such as chromospheric activity, as well as imperfections in the light curve detrending process, can create systematic artifacts that may produce fictitious signals in the eclipse timings. We present a method to measure precise eclipse times in the presence of distorted light curves, such as in contact and near-contact binaries which exhibit continuously changing light levelsmore » in and out of eclipse. We identify 236 systems for which we find a timing variation signal compatible with the presence of a third body. These are modeled for the light travel time effect and the basic properties of the third body are derived. This study complements J. A. Orosz et al. (in preparation), which focuses on eclipse timing variations of longer period binaries with flat out-of-eclipse regions. Together, these two papers provide comprehensive eclipse timings for all binaries in the Kepler Eclipsing Binary Catalog, as an ongoing resource freely accessible online to the community.« less

Candidates of eclipsing multiples based on extraneous eclipses on binary light curves: KIC 7622486, KIC 7668648, KIC 7670485 and KIC 8938628

NASA Astrophysics Data System (ADS)

Zhang, Jia; Qian, Sheng-Bang; He, Jian-Duo

2017-02-01

Four candidates of eclipsing multiples, based on new extraneous eclipses found on Kepler binary light curves, are presented and studied. KIC 7622486 is a double eclipsing binary candidate with orbital periods of 2.2799960 d and 40.246503 d. The two binary systems do not eclipse each other in the line of sight, but there is mutual gravitational influence between them which leads to the small but definite eccentricity of 0.0035(0.0022) associated with the short 2.2799960 d period orbit. KIC 7668648 is a hierarchical quadruple system candidate, with two sets of solid 203 ± 5 d period extraneous eclipses and another independent set of extraneous eclipses. A clear and credible extraneous eclipse is found on the binary light curve of KIC 7670485 which makes it a triple system candidate. Two sets of extraneous eclipses with periods of about 390 d and 220 d are found on KIC 8938628 binary curves, which not only confirm the previous conclusion of the 388.5 ± 0.3 triple system, but also indicate new additional objects that make KIC 8938628 a hierarchical quadruple system candidate. The results from these four candidates will contribute to the field of eclipsing multiples.

Poster 16: Eclipse-induced changes of Titan's meteorology at equinox

NASA Astrophysics Data System (ADS)

Tokano, Tetsuya

2016-06-01

Titan experiences solar eclipses by Saturn on ˜20 consecutive orbits around equinox for durations of up to ˜6 hours. The impact of these eclipses on Titan's surface, lower atmosphere and middle atmosphere is investigated by a global climate model. When an eclipse commences, the surface temperature on the subsaturnian side drops by up to 0.3 K, so that the diurnal maximum surface temperature remains lower than on the antisaturnian side, which is never eclipsed. By contrast, the tropospheric air temperature does not abruptly decrease during the eclipses because of the large thermal inertia, but the diurnal mean temperature slightly decreases. The surface wind at low latitudes becomes less gusty in the presence of eclipse due to damping of turbulence. The troposphere outside the planetary boundary layer is not sensitive to eclipses. In most parts of the stratosphere and mesosphere the temperature decreases by up to 2 K due to eclipses, but there are also layers, which experience relative warming due to thermal contraction of the underlying layers. The temperature in the middle atmosphere rapidly recovers after the end of the eclipse season. Eclipse-induced cooling and warming changes the zonal wind speed by a few m/s due to thermal wind adjustment to changing latitudinal temperature gradients.

The quality of pediatric orthopaedic information on the internet.

Winship, Brenton; Grisell, Margaret; Yang, Carolyn B; Chen, Rachel X; Bauer, Andrea S

2014-06-01

Many patients use the Internet for health information. However, there are few guarantees to the reliability and accuracy of this information. This study examined the quality and content of the Internet Web pages for 10 common pediatric orthopaedic diagnoses. We identified 10 common diagnoses in pediatric orthopaedics: brachial plexus injury, cerebral palsy, clubfoot, developmental dysplasia of the hip, leg length discrepancy, osteochondroma, polydactyly, scoliosis, spina bifida, and syndactyly. We used 2 of the most popular search engines to identify the top 10 Web sites for each disease. We evaluated the Web sites utilizing both the quality-based Health On the Net (HON) Foundation criteria and our own content-based grading sheets. The custom grading sheets focused on essential information about disease summary, pathogenesis, diagnosis, treatment, and prognosis. Three orthopaedic surgeons graded 98 academic, commercial, nonprofit, and physicians' Web sites for 10 diseases. Academic Web sites scored the highest in content (mean, 60.8% ± 15.5%), whereas commercial Web sites scored the lowest (mean, 46.7% ± 22.2%). Among the diagnoses, osteochondroma Web sites had the highest content scores (mean, 75.8% ± 11.8%), whereas polydactyly Web sites had the lowest content scores (mean, 39.3% ± 15.7%). In contrast, Web sites about developmental dysplasia of the hip had the highest HON scores (65.0 ± 11.1), whereas those about brachial plexus birth palsy scored the lowest (42.6% ± 16.9%). Among the content subgroups, scores were generally higher for disease summary and diagnostics and lower for prognosis. The Internet Web sites reviewed demonstrated a wide range of content and information. We found that nonprofit and academic Web sites were the most reliable sources, whereas commercial and, surprisingly, physician-run Web sites were the least reliable. We advise physicians to talk to their patients about the information they get on the Internet and how it dictates their expectations. We hope this study, combined with further understanding of how our patients use this information, can help improve the Internet content. Physicians should know that their patients may be receiving misleading information from the Internet and be able to discuss this with their patients.

The Great American Eclipse: Lessons Learned from Public Education

NASA Astrophysics Data System (ADS)

Edson, Shauna Elizabeth; Phoebe Waterman Haas Public Observatory

2018-01-01

The total solar eclipse of 2017 was a high-profile opportunity for nationwide public education. Astronomy experts suddenly became vital sources of information for a lay population whose interest in the eclipse greatly surpassed expectations. At the National Air and Space Museum, we leveraged our relatively accessible location and particularly diverse audience to help thousands of people, from novices to enthusiasts, prepare to view the eclipse safely. The goal was to empower all people so they could experience this unique astronomical event, understand what was happening, and observe the Sun safely. Over the course of two years spent talking with the public about the eclipse, we encountered common misconceptions, worries about safety or liability, and people experiencing confusion or information overload. We developed guidelines for handling these challenges, from correcting misinformation to managing the sudden spike in demand for glasses just before August 21.In particular, we helped people understand the following essential points:- The total phase of the eclipse is only visible from a limited path.- The partial eclipse is visible from a large area outside the path of totality.- The eclipse takes up to three hours from start to finish, providing ample time for viewing.- The Sun can be observed safely using several methods, including but not limited to eclipse glasses.- The eclipse happens because the Moon’s orbit is taking it directly between the Sun and the Earth.- Eclipses do not happen every month because the Moon’s orbit is tilted with respect to the Earth's orbital plane.- Students in schools can safely view the eclipse, with proper protection and supervision, to prevent eye damage and minimize liability.Public education about the eclipse appears to have been successful, as evidenced by the large number of people who saw their first total solar eclipse and the absence of reported eye damage cases. Amidst the excitement, photographs, and stories that emerged from the eclipse, there are valuable lessons that will be useful in helping the public prepare for future eclipses, in 2024 and beyond.

2016 SPD: Day 3

2016-06-01

Editors note:This week were in Boulder, Colorado at the47th meeting of the AAS Solar Physics Division (SPD). Follow along to catch some of the latest news from the field of solar physics!Yesterdayspress conference was titled Preparing for the 2017 Great American Eclipse. Four speakers highlighted both outreach and research projects that are planned for the eclipse that will cross the continental United States on August 21st next year.Eclipse from High AltitudeFirst up, Angela Des Jardins (Montana Space Grant Consortium) introduced us to the nationwide Eclipse Ballooning Project.An eclipse as seen from the ISS. Being up high gives you a very different perspective on eclipses! [NASA]The last total solar eclipse in the continental United States was in 1979, and people were told to stay inside and watch from their TVs! For the next total solar eclipse in the US, we want the opposite: for everyone to be outdoors and in the path of totality to watch (with eclipse glasses lets be safe)! This eclipse is a fantastic educational opportunity, and a way to reach an enormous audience.And what better way to experience the eclipse than to be involved? The Eclipse Ballooning Project is involving more than 50 student teams from 30 states to fly high-altitude balloons at 20 locations along the total eclipse path. These balloons will send live videos and images from the edge of space to the NASA website.Why? Being someplace high up provides an entirely different view for an eclipse! Instead of looking up to watch the Moon slide in front of the Sun, you can look down to watch the Moons shadow race across the Earths surface at thousands of miles per hour. This unique perspective is rare, and has certainly never been covered live. This will be an awesome addition to other coverage of the eclipse!At Maximum TotalityThe next speaker, Gordon Emslie, described the outreach efforts planned at his institution, Western Kentucky University (WKU). The location where the eclipse totality will last the longest 2 minutes and 40 seconds is the small town of Hopkinsville, KY. WKU is located a little over an hour away, and both locations are prepared for a large influx of people on eclipse day!Partial solar eclipse as viewed by the space-based Solar Dynamics Observatory. [NASA/SDO]WKU is located just off the centerline of eclipse path, which has some advantages: this provides better viewing of some of the chromospheric features of the Sun during the eclipse, like priminences and solar loops. WKU is setting up a variety of educational and public outreach activities at their football stadium and the WKU farm, and they encourage you to come visit for the eclipse!In addition, they are participating in a nationwide experiment called Citizen CATE, short for the Continental American Telescopic Eclipse. This project will use 60 telescopes spanning the 2500 mile path of totality to record continuous data of the eclipse as it travels across the US. The result will be data of a remarkable 90 minutes of totality, revealing the activity of the solar corona and providing an extended view of the eclipse as has never been seen before.Science During the EclipseNext up was Shadia Habbal (University of Hawaii), who is a co-leader of the AAS 2017 Eclipse Task Force. In addition to her education and outreach efforts associated with the eclipse, however, Habbal is a solar eclipse researcher. She and her collaborators are known as the Solar Wind Sherpas, due to the fact that they hand-carry their science equipment around the world for solar eclipses!Solar corona during a 2008 eclipse, with color overlay indicating emission from highly ionized iron lines. [Habbal et al. 2010]The primary science done during solar eclipses is the study of the solar corona, the region that extends from the solar surface out to several solar radii. This region is too faint to observe normally, but when the light from the Suns disk is blocked out, we can examine it.Unfortunately, the space telescopes that observe the Sun all have relatively narrow fields of view. But during an eclipse, we can gain the larger context for the corona with ground-based observations, with the Moon conveniently blocking the light from the Suns disk! The cover photo is a spectacular example of this.Observations of the corona during eclipses can provide information on both enormous events, like coronal mass ejections, and faint dynamical features, like plasma instabilities and expanding loops. In addition, we can learn about the plasma properties by examining emission from highly charged ions. The upcoming eclipse should provide a great opportunity to do some coronal science!A Unique OpportunityThe final press-conference speaker for the meeting was Jay Pasachoff (Williams College and Caltech), a veteran solar eclipse observer who was able to speak to what we could expect if we make it into the path of totality next year.Path of totality across the continental US for the August 2017 eclipse. [Fred Espenak/NASA GSFC]Pasachoff pointed out that there are nearly 12 million people located within the band of totality. There are probably another 200 million within a days drive! He strongly encouraged anyone able to make it to the path of totality to do so, pointing out that the experience in person is completely unlike the experience of watching a video. The process of watching the world around you go dark, he says, is something that simply isnt captured when you watch an eclipse on TV.If you plan to travel for the eclipse, Pasachoffs recommendation is to aim for the northwest end of the path of totality, rather than the southeast end surprisingly, weather statistics suggest you have a better chance of not getting clouded out in the northwest.We now have a year left to educate everyone likely to view the eclipse on when and how to view it safely! Accordingly, Pasachoff concluded the conference by providing a series of links on where to find more information:eclipses.infototalsolareclipse.orgGreatAmericanEclipse.comeclipsophile.com

An evaluation of the behaviour-change techniques used on Canadian cancer centre Web sites to support physical activity behaviour for breast cancer survivors

2017-01-01

Background Cancer centre Web sites can be a useful tool for distributing information about the benefits of physical activity for breast cancer (bca) survivors, and they hold potential for supporting health behaviour change. However, the extent to which cancer centre Web sites use evidence-based behaviour change techniques to foster physical activity behaviour among bca survivors is currently unknown. The aim of our study was to evaluate the presentation of behaviour-change techniques on Canadian cancer centre Web sites to promote physical activity behaviour for bca survivors. Methods All Canadian cancer centre Web sites (n = 39) were evaluated by two raters using the Coventry, Aberdeen, and London–Refined (calo-re) taxonomy of behaviour change techniques and the eEurope 2002 Quality Criteria for Health Related Websites. Descriptive statistics were calculated. Results The most common behaviour change techniques used on Web sites were providing information about consequences in general (80%), suggesting goal-setting behaviour (56%), and planning social support or social change (46%). Overall, Canadian cancer centre Web sites presented an average of M = 6.31 behaviour change techniques (of 40 that were coded) to help bca survivors increase their physical activity behaviour. Evidence of quality factors ranged from 90% (sites that provided evidence of readability) to 0% (sites that provided an editorial policy). Conclusions Our results provide preliminary evidence that, of 40 behaviour-change techniques that were coded, fewer than 20% were used to promote physical activity behaviour to bca survivors on cancer centre Web sites, and that the most effective techniques were inconsistently used. On cancer centre Web sites, health promotion specialists could focus on emphasizing knowledge mobilization efforts using available research into behaviour-change techniques to help bca survivors increase their physical activity.

Evaluation of Norwegian cancer hospitals' Web sites and explorative survey among cancer patients on their use of the Internet

PubMed Central

2001-01-01

Background Hospital homepages should provide comprehensive information on the hospital's services, such as departments and treatments available, prices, waiting time, leisure facilities, and other information important for patients and their relatives. Norway, with its population of approximately 4.3 million, ranks among the top countries globally for its ability to absorb and use technology. It is unclear to what degree Norwegian hospitals and patients use the Internet for information about health services. Objectives This study was undertaken to evaluate the quality of the biggest Norwegian cancer hospitals' Web sites and to gather some preliminary data on patients' use of the Internet. Methods In January 2001, we analyzed Web sites of 5 of the 7 biggest Norwegian hospitals treating cancer patients using a scoring system. The scoring instrument was based on recommendations developed by the Norwegian Central Information Service for Web sites and reflects the scope and depth of service information offered on hospital Web pages. In addition, 31 cancer patients visiting one hospital-based medical oncologist were surveyed about their use of the Internet. Results Of the 7 hospitals, 5 had a Web site. The Web sites differed markedly in quality. Types of information included - and number of Web sites that included each type of information - were, for example: search option, 1; interpreter service, 2; date of last update, 2; postal address, phone number, and e-mail service, 3; information in English, 2. None of the Web sites included information on waiting time or prices. Of the 31 patients surveyed, 12 had personal experience using the Internet and 4 had searched for medical information. The Internet users were significantly younger (mean age 47.8 years, range 28.4-66.8 years) than the nonusers (mean age 61.8 years, range 33.1-90.0 years) ( P= 0.007). Conclusions The hospitals' Web sites offer cancer patients and relatives useful information, but the Web sites were not impressive. PMID:11772545

Eclipse Soundscapes Project: Making the August 21, 2017 Total Solar Eclipse Accessible to Everyone

NASA Astrophysics Data System (ADS)

Winter, H. D., III

2017-12-01

The Eclipse Soundscapes Project delivered a multisensory experience that allowed the blind and visually impaired to engage with the August 21, 2017 total solar eclipse along with their sighted peers in a way that would not have been possible otherwise. The project, from the Smithsonian Astrophysical Observatory and NASA's Heliophysics Education Consortium, includes illustrative audio descriptions of the eclipse in real time, recordings of the changing environmental sounds during the eclipse, and an interactive "rumble map" app that allows users to experience the eclipse through touch and sound. The Eclipse Soundscapes Project is working with organizations such as the National Parks Service (NPS), Science Friday, and Brigham Young University and by WGBH's National Center for Accessible Media (NCAM) to bring the awe and wonder of the total solar eclipse and other astronomical phenomena to a segment of the population that has been excluded from and astronomy and astrophysics for far too long, while engaging all learners in new and exciting ways.

Secure Web-Site Access with Tickets and Message-Dependent Digests

USGS Publications Warehouse

Donato, David I.

2008-01-01

Although there are various methods for restricting access to documents stored on a World Wide Web (WWW) site (a Web site), none of the widely used methods is completely suitable for restricting access to Web applications hosted on an otherwise publicly accessible Web site. A new technique, however, provides a mix of features well suited for restricting Web-site or Web-application access to authorized users, including the following: secure user authentication, tamper-resistant sessions, simple access to user state variables by server-side applications, and clean session terminations. This technique, called message-dependent digests with tickets, or MDDT, maintains secure user sessions by passing single-use nonces (tickets) and message-dependent digests of user credentials back and forth between client and server. Appendix 2 provides a working implementation of MDDT with PHP server-side code and JavaScript client-side code.

To explore the role of Web-based platforms in behavioral health, the study examined usage of a Web site for supporting training and implementation of an evidence-based intervention. Using data from an online registration survey and Google Analytics, the investigators examined user characteristics and Web site utilization. Site engagement was substantial across user groups. Visit duration differed by registrants' characteristics. Less experienced clinicians spent more time on the Web site. The training section accounted for most page views across user groups. Individuals previously trained in the Cognitive-Behavioral Intervention for Trauma in Schools intervention viewed more implementation assistance and online community pages than did other user groups. Web-based platforms have the potential to support training and implementation of evidence-based interventions for clinicians of varying levels of experience and may facilitate more rapid dissemination. Web-based platforms may be promising for trauma-related interventions, because training and implementation support should be readily available after a traumatic event.

Keesee, A. M.; Williamson, K.; Robertson-Honecker, J.

2017-12-01

West Virginia experienced up to 90% coverage during the Great American Solar Eclipse on August 21st. To reach the greatest number of West Virginians, we targeted educators and the 4-H program to provide those community leaders with the tools to help students learn about and safely view the eclipse. We developed a website that consolodated relevant eclipse activities, fact sheets, and outreach videos to train educators and others in the public about the science of the eclipse and how to view a partial eclipse safely. The 4-H Summer Experiement used at all 4-H summer camps and events was designed to focus on the eclipse. We distributed over 20,000 custom designed eclipse glasses. These were distributed to teachers through an online request system and to 4-H members involved in summer activities. We hosted a pre-eclipse event on the campus of West Virginia University for the public to learn about the science of the eclipse, relevant research being conducted at the university, and provide tips for safe viewing. Student volunteers were available on campus during the day of the eclipse to hand out glasses and answer questions. We will present the results of our outreach and events as well as lessons learned for the 2024 eclipse. Support for this project was provided by the WVU Department of Physics and Astronomy, WVU Extension, the WV Space Grant Consortium, a WVU internal grant, the Green Bank Observatory, and individual supporters of a crowdfunding campaign.

Program Director as Webmaster? Analysis of 131 Anesthesiology Department Web Sites and Program Director Web Site Involvement and Opinion Survey.

PubMed

Daneshpayeh, Negin; Lee, Howard; Berger, Jeffrey

2013-01-01

The last formal review of academic anesthesiology department Web sites (ADWs) for content was conducted in 2009. ADWs have been rated as very important by medical students in researching residency training programs; however, the rapid evolution of sites require that descriptive statistics must be more current to be considered reliable. We set out to provide an updated overview of ADW content and to better understand residency program directors' (PD) role and comfort with ADWs. Two independent reviewers (ND and HL) analyzed all 131 Accreditation Council for Graduate Medical Education (ACGME) accredited ADWs. A binary system (Yes/No) was used to determine which features were present. Reviewer reliability was confirmed with inter-rater reliability and percentage agreement calculation. Additionally, a blinded electronic survey (Survey Monkey, Portland, OR) was sent to anesthesiology residency PDs via electronic mail investigating the audiences for ADWs, the frequency of updates and the degree of PD involvement. 13% of anesthesiology departments still lack a Web site with a homepage with links to the residency program and educational offerings (18% in 2009). Only half (55%) of Web sites contain information for medical students, including clerkship information. Furthermore, programs rarely contain up-to-date calendars (13%), accreditation cycle lengths (11%), accreditation dates (7%) or board pass rates (6%). The PD survey, completed by 42 of 131 PDs, noted a correlation (r = 0.36) between the number of years as PD and the frequency of Web site updates - less experienced PDs appear to update their sites more frequently (p = 0.03). Although 86% of PDs regarded a Web site as "very" important in recruitment, only 9% felt "very" comfortable with the skills required to advertise and market a Web site. Despite the overall increase in ADW content since 2009, privacy concerns, limited resources and time constraints may prevent PDs from providing the most up-to-date Web sites for applicants and other interested audiences. PDs are aware of value of Web sites for recruitment, are typically involved in determining ADW content, but few feel very comfortable marketing a training program on the Web.

2017-02-01

Patient care problems arise when health care consumers and professionals find health information on the Internet because that information is often inaccurate. To mitigate this problem, nurses can develop Web literacy and share that skill with health care consumers. This study evaluated a Web-literacy intervention for undergraduate nursing students to find reliable Web-based health information. A pre- and postsurvey queried undergraduate nursing students in an informatics course; the intervention comprised lecture, in-class practice, and assignments about health Web site evaluation tools. Data were analyzed using Wilcoxon and ANOVA signed-rank tests. Pre-intervention, 75.9% of participants reported using Web sites to obtain health information. Postintervention, 87.9% displayed confidence in using an evaluation tool. Both the ability to critique health Web sites (p = .005) and confidence in finding reliable Internet-based health information (p = .058) increased. Web-literacy education guides nursing students to find, evaluate, and use reliable Web sites, which improves their ability to deliver safer patient care. [J Nurs Educ. 2017;56(2):110-114.].

Doshi, Amol; Patrick, Kevin; Sallis, James F; Calfas, Karen

2003-01-01

Physical activity (PA) Web sites were assessed for their use of behavior change theories, including constructs of the health belief model, Transtheoretical Model, social cognitive theory, and the theory of reasoned action and planned behavior. An evaluation template for assessing PA Web sites was developed, and content validity and interrater reliability were demonstrated. Two independent raters evaluated 24 PA Web sites. Web sites varied widely in application of theory-based constructs, ranging from 5 to 48 on a 100-point scale. The most common intervention strategies were general information, social support, and realistic goal areas. Coverage of theory-based strategies was low, varying from 26% for social cognitive theory to 39% for health belief model. Overall, PA Web sites provided little assessment, feedback, or individually tailored assistance for users. They were unable to substantially tailor the on-line experience for users at different stages of change or different demographic characteristics.

The Solar Eclipse Predictions of Chiljeongsam-Oepyeon in Early Choseon

NASA Astrophysics Data System (ADS)

Ahn, Young Sook; Lee, Yong Sam

2004-12-01

The history books of East Asia about astronomical phenomena have the more records of the solar eclipse frequently than any other ones. It is because traditionally, the solar eclipse meaned the fate of dynasty and the king's rule. The Sun, the biggest thing in the heaven symbolized the king, and the solar eclipse foresaw that the king had the problem in private including the body, and the country might suffer from difficulties in a great scale. So the king and all of the ministers used to gather to hold a ceremony named Gusikrye which solar eclipse may pass safely. Consequently, kings always had concernments on collecting informations of solar eclipse. Inspite of importance of solar eclipse predictions, but at the beginning of the Choseon, the predictions of the solar eclipse didn't fit. King Sejong compiled the Chiljeongsan-naepion and the Chiljeongsan-oepyeon to calculate the celestial phenomena including the solar eclipse. By the publications of these two books, the calendar making system of Choseon was firmly established. The Chiljeongsan-oepyeon adopted Huihui calendar of Arabia. The Solar eclipse predictions of Chiljeongsan-oepyeon were relative correct compared to modern method in early Choseon dynasty.

Changes in Latitude, Changes in Attitude: U.S. Naval Observatory Observations of Solar Eclipses 1869 to the Present

NASA Astrophysics Data System (ADS)

Chizek Frouard, Malynda R.; Towne, Linda; Kaplan, George H.

2017-01-01

In anticipation of the 2017 August 21 total solar eclipse over the continental United States, the history of U.S. Naval Observatory eclipse observations illustrates the changes in science, technology, and policy over the past 148 years.USNO eclipse observations began in 1869, when staff traveled to Des Moines, Iowa and the Bering Strait to look for intra-mercurial planets and to observe the solar corona. During the golden age of eclipse expeditions, the USNO officially participated in a dozen expeditions between 1869 and 1929. Seven of these expeditions were to US locations: 1869 in Iowa; 1878 in Colorado, Wyoming, and Texas; 1880 in California; 1900 in Georgia and North Carolina; 1918 in Oregon; 1923 in California; and 1925 in New York. A total solar eclipse has not traced a path across the width of the continental US since 1918 although several eclipses have passed over parts of the US since then.A few official expeditions occurred later in the 20th century to measure the solar diameter, including a total eclipse in the northwest US in 1979 and an annular eclipse across the southeast in 1984. However, observations began transitioning to mostly personal adventures as individual astronomers arranged unofficial trips.Historians can use the USNO Multi-year Interactive Computer Almanac (MICA) to compute local circumstances for solar eclipses world-wide starting with the annual eclipse of 1800 April 24, which was visible from Alaska. Those looking to make history in 2017 may consult the USNO 2017 August 21 Solar Eclipse Resource page (http://aa.usno.navy.mil/data/docs/Eclipse2017.php).

Communicating laboratory results through a Web site: Patients' priorities and viewpoints.

Sabahi, Azam; Ahmadian, Leila; Mirzaee, Moghademeh

2018-02-28

Patients can access laboratory results using various technologies. The aim of this study was to integrate the laboratory results into the hospital Web site based on patients' viewpoints and priorities and to measure patients' satisfaction. This descriptive-analytical study was conducted in 2015. First, a questionnaire was distributed among 200 patients to assess patients' priorities to receive laboratory results through the Web site. Second, those who agreed (n = 95) to receive their laboratory results through the Web site were identified. Then, the required changes were made to the hospital Web site based on patients' viewpoints and priorities. Third, patients were divided into two groups. The first group received their laboratory results through the Web site on the date had been announced during their visit to the laboratory. The second group was informed by SMS once their results were shown on the Web site. After receiving laboratory results, patients' satisfaction was evaluated. More than half of the participants (n = 53, 55.8%) were highly satisfied with receiving the results electronically.

Building on the US Eclipse Experience in Schools, with the Public, and Beyond the US

NASA Astrophysics Data System (ADS)

Simmons, Mike; Chee, Zoe; Bartolone, Lindsay

2018-01-01

Astronomers Without Borders (AWB) organized several programs for the August 21, 2017 total solar eclipse, both before and after the event, to increase participation, build on the inspiration of the eclipse, share the eclipse experience, and prepare for the eclipse in 2024.AWB focused on preparing institutions that were least likely to receive resources despite extensive nationwide efforts. AWB distributed more than 100,000 donated glasses, to isolated schools, children's cancer hospitals, abused women’s shelters, and other institutions without access to other resource providers.AWB’s Building on the Eclipse Education Program builds on the inspiration of the eclipse for STEM education. The program uses a small, personal spectroscope kit to study sunlight in different scientific fields and includes free classroom activities that meet NGSS standards.A program to collect eclipse observing glasses for schools in developing countries for future eclipses was announced around the time of the eclipse and quickly went viral, with coverage by national and innumerable local media outlets. This effort builds on AWB’s earlier programs for schools in Africa and in South America for past eclipses. Well over one million pairs are expected, as compared to the tens of thousands AWB provided through crowdfunding for previous efforts. Nearly 1000 glasses collection centers were created spontaneously, without a public call. Factors leading to widespread and diverse public participation will be presented.A program calling for first-time eclipse observers to share their experiences addresses a major issue in encouraging people to travel to the path of totality. Expert and eclipse-enthusiast testimony often fails to convince people of the value of the experience of totality as “a few minutes of darkness.” This program will share the disconnect between expectation and experience from first-time “ordinary” observers to encourage others to travel to the path of totality for the total solar eclipse in 2024.Analysis and planned follow-up and expanded programs will also be described.

Satellite observations of surface temperature during the March 2015 total solar eclipse

PubMed Central

2016-01-01

The behaviour of remotely sensed land surface temperatures (LSTs) from the spinning-enhanced visible and infrared imager (SEVIRI) during the total solar eclipse of 20 March 2015 is analysed over Europe. LST is found to drop by up to several degrees Celcius during the eclipse, with the minimum LST occurring just after the eclipse mid-point (median=+1.5 min). The drop in LST is typically larger than the drop in near-surface air temperatures reported elsewhere, and correlates with solar obscuration (r=−0.47; larger obscuration = larger LST drop), eclipse duration (r=−0.62; longer duration = larger LST drop) and time (r=+0.37; earlier eclipse = larger LST drop). Locally, the LST drop is also correlated with vegetation (up to r=+0.6), with smaller LST drops occurring over more vegetated surfaces. The LSTs at locations near the coast and at higher elevation are also less affected by the eclipse. This study covers the largest area and uses the most observations of eclipse-induced surface temperature drops to date, and is the first full characterization of satellite LST during an eclipse (known to the author). The methods described could be applied to Geostationary Operational Environmental Satellite (GOES) LST data over North America during the August 2017 total solar eclipse.

2002-01-01

For the past four years the Science Directorate at Marshall Space Flight Center has carried out a diverse program of science communication through the web resources on the Internet. The program includes extended stories about NAS.4 science, a curriculum resource for teachers tied to national education standards, on-line activities for students, and webcasts of real-time events. Events have involved meteor showers, solar eclipses, natural very low frequency radio emissions, and amateur balloon flights. In some cases broadcasts accommodate active feedback and questions from Internet participants. We give here, examples of events, problems, and lessons learned from these activities.

Developing a value-added Web site.

2000-03-01

Once a healthcare organization has decided to establish a Web site on the Internet, it must next determine its implementation strategy, based on a full understanding of the goals of the site and the range of Web content and service offerings available in the marketplace. Although some organizations may choose to develop and maintain a Web site using exclusively in-house resources, most healthcare organizations will find that they can minimize the costs associated with this effort by making judicious use of outsourcing services. Whichever approach is used, it is important that financial managers charged with allocating resources for Web-site development and maintenance understand the implications, including relative financial impact, of key issues and options.

Symbolism and discovery: eclipses in art.

PubMed

Blatchford, Ian

2016-09-28

There is a fascinating tradition of depicting solar eclipses in Western art, although these representations have changed over time. Eclipses have often been an important feature of Christian iconography, but valued as much for their biblical significance as for the splendour of the physical event. However, as Western culture passed through the Renaissance and Enlightenment the depictions of eclipses came to reflect new astronomical knowledge and a thirst for rational learning well beyond the confines of the church and other elites. Artists also played a surprisingly important role in helping scientists in the nineteenth century understand and record the full phenomena of an eclipse, even as the advent of photography also came to solve a number of scientific puzzles. In the most recent century, artists have responded to eclipses with symbolism, abstraction and playfulness.This article is part of the themed issue 'Atmospheric effects of solar eclipses stimulated by the 2015 UK eclipse'. © 2016 The Author(s).

Spectral irradiance curve calculations for any type of solar eclipse

NASA Technical Reports Server (NTRS)

Deepak, A.; Merrill, J. E.

1974-01-01

A simple procedure is described for calculating the eclipse function (EF), alpha, and hence the spectral irradiance curve (SIC), (1-alpha), for any type of solar eclipse: namely, the occultation (partial/total) eclipse and the transit (partial/annular) eclipse. The SIC (or the EF) gives the variation of the amount (or the loss) of solar radiation of a given wavelength reaching a distant observer for various positions of the moon across the sun. The scheme is based on the theory of light curves of eclipsing binaries, the results of which are tabulated in Merrill's Tables, and is valid for all wavelengths for which the solar limb-darkening obeys the cosine law: J = sub c (1 - X + X cost gamma). As an example of computing the SIC for an occultation eclipse which may be total, the calculations for the March 7, 1970, eclipse are described in detail.

Solar retinopathy refers to damage to the central macula caused by exposure to intense solar radiation, most frequently observed after a solar eclipse. Description of the morphological changes in spectral domain optical coherence tomography (SD-OCT) and the clinical course in patients with acute solar retinopathy. The study included a retrospective analysis of 12 eyes from 7 patients with solar retinopathy after the partial solar eclipse on 20 March 2015. Best corrected visual acuity, fundus changes and SD-OCT findings were analyzed. Out of the 7 patients 5 underwent treatment with 1 mg prednisolone per kg body weight. The average age of the patients was 30.1±13.1 years. Best corrected visual acuity was 0.65 at initial presentation. In the acute stage all affected eyes showed a small yellowish lesion in the centre of the fovea in the fundoscopic examination. In SD-OCT the continuity of all layers in the foveola appeared disrupted. In the follow-up examination these changes were partially resolved. After 2 months SD-OCT revealed a small defect of the ellipsoid zone. In one patient the defect could not be shown due to slightly excentric imaging sections. Best corrected visual acuity increased to 0.97. The SD-OCT is an appropriate tool to determine the exact localization of the site of damage and for follow-up examination in solar retinopathy. In the acute phase it shows a disruption of the continuity of all layers in the foveola. Despite good recovery of visual acuity a small central defect of the ellipsoid zone remains in the long term.

Surfing for back pain patients: the nature and quality of back pain information on the Internet.

Li, L; Irvin, E; Guzmán, J; Bombardier , C

2001-03-01

A prospective, systematic review of web sites related to back pain. To assess the nature and quality of back pain-related information on the World Wide Web during a 2-year period. The Internet has become a rich source of medical information. Limited knowledge is available, however, about the quality of online resources. Although previous systematic reviews on medical-related web sites found problems in varying degrees with the credibility of information, no such review was conducted to assess the back pain-related sites. A search of web sites was conducted in November 1996 using five search engines (AltaVista, Infoseek, Lycos, Yahoo, and Magellan) and two key terms ("back pain" and "back problems"). A sample of sites was evaluated by two independent reviewers. Each site was described by the type and nature of the sponsor, target audience, and content. Overall quality was assessed in terms of evidence-based information available. Seventy-four web sites were reviewed in 1996, and nine of them (12.2%) were identified as high-quality sites. Advertising was the focus of 80.8% of the sites. Eleven sites (14.9%) were found to be discontinued 1 year later, and 20 (27.0%) were not accessible by the reviewers at the 2-year follow-up evaluation. Of the remaining 54 sites, 44.4% were produced by for-profit companies, and most sites targeted people with back pain (63.0%). Only seven out of the nine high-quality sites held their ratings at the 2-year follow-up evaluation. Most back pain-related web sites can be classified as advertising. The quality varied considerably, resulting in difficulties for patients to find useful information in this field. The increasing number of people seeking medical information on the Web creates a need for more high quality sites. Further, systematic review of web sites should be encouraged to monitor the accuracy of Internet publication.

Individual belief and knowledge about cancer were shown to influence coping and compliance of patients. Supposing that the Internet information both has impact on patients and reflects patients' information needs, breast cancer web sites in English and German language were evaluated to assess the information quality and were compared with each other to identify intercultural differences. Search engines returned 10 616 hits related to breast cancer. Of these, 4590 relevant hits were analysed. In all, 1888 web pages belonged to 132 English-language web sites and 2702 to 65 German-language web sites. Results showed that palliative therapy (4.5 vs 16.7%; P=0.004), alternative medicine (18.2 vs 46.2%; P<0.001), and disease-related information (prognosis, cancer aftercare, self-help groups, and epidemiology) were significantly more often found on German-language web sites. Therapy-related information (including the side effects of therapy and new studies) was significantly more often given by English-language web sites: for example, details about surgery, chemotherapy, radiotherapy, hormone therapy, immune therapy, and stem cell transplantation. In conclusion, our results have implications for patient education by physicians and may help to improve patient support by tailoring information, considering the weak points in information provision by web sites and intercultural differences in patient needs.

Usability of American Nurses Association State Web Sites: A Follow-up Evaluation.

Koch, Gina; Wakefield, Bonnie J; Alexander, Gregory L; Wilson, Melissa A; Becker, Colleen

2016-05-01

The American Nurses Association supports professional nurses through Web sites administered by state nursing associations, providing important information for current and potential members. Optimal usability of these Web sites is critical for nurses to obtain the information they seek. Heuristic evaluations are general criteria used to evaluate the usability of technology such as Web sites. A study published in 2014, using heuristic criteria from Nielsen's 10 principles and Health on The Web, evaluated 27 state nursing Web sites to identify usability concerns that could prevent nurses from obtaining accurate information regarding state nursing practice. The purpose of this study is to conduct a second heuristic evaluation to assess for changes in a subset of 12 Web sites. The analysis comparing the evaluation from 2012 to 2014 found that mean scores increased and variance decreased; however, no statistically significant difference was found between the two studies. Scores increased in 2014 for "help users to diagnose, and recover from errors," "match between the system and real world," and "consistency and standards." Scores decreased due to absence of mission statements and identification of intended audience. Ideally, Web site designers will use the feedback from this study and make changes that improve their usability to provide information to nurses.

Food marketing contributes to childhood obesity. Food companies commonly place display advertising on children's web sites, but few studies have investigated this form of advertising. Document the number of food and beverage display advertisements viewed on popular children's web sites, nutritional quality of advertised brands and proportion of advertising approved by food companies as healthier dietary choices for child-directed advertising. Syndicated Internet exposure data identified popular children's web sites and food advertisements viewed on these web sites from July 2009 through June 2010. Advertisements were classified according to food category and companies' participation in food industry self-regulation. The percent of advertisements meeting government-proposed nutrition standards was calculated. 3.4 billion food advertisements appeared on popular children's web sites; 83% on just four web sites. Breakfast cereals and fast food were advertised most often (64% of ads). Most ads (74%) promoted brands approved by companies for child-directed advertising, but 84% advertised products that were high in fat, sugar and/or sodium. Ads for foods designated by companies as healthier dietary choices appropriate for child-directed advertising were least likely to meet independent nutrition standards. Most foods advertised on popular children's web sites do not meet independent nutrition standards. Further improvements to industry self-regulation are required. © 2013 The Authors.

Geospatial Analysis of Low-frequency Radio Signals Collected During the 2017 Solar Eclipse

NASA Astrophysics Data System (ADS)

Liles, W. C.; Nelson, J.; Kerby, K. C.; Lukes, L.; Henry, J.; Oputa, J.; Lemaster, G.

2017-12-01

The total solar eclipse of 2017, with a path that crosses the continental United States, offers a unique opportunity to gather geospatially diverse data. The EclipseMob project has been designed to crowdsource this data by building a network of citizen scientists across the country. The project focuses on gathering low-frequency radio wave data before, during, and after the eclipse. WWVB, a 60 KHz transmitter in Ft. Collins, CO operated by the National Institutes of Standard and Technology, will provide the transmit signal that will be observed by project participants. Participating citizen scientists are building simple antennas and receivers designed by the EclipseMob team and provided to participants in the form of "receiver kits." The EclipseMob receiver downsamples the 60 KHz signal to 18 KHz and supplies the downsampled signal to the audio jack of a smartphone. A dedicated app is used to collect data and upload it to the EclipseMob server. By studying the variations in WWVB amplitude observed during the eclipse at over 150 locations across the country, we aim to understand how the ionization of the D layer of the ionosphere is impacted by the eclipse as a function of both time and space (location). The diverse locations of the EclipseMob participants will provide data from a wide variety of propagation paths - some crossing the path of the total eclipse, and some remaining on the same side of the eclipse path as the transmitter. Our initial data analysis will involve identifying characteristics that define geospatial relationships in the behavior of observed WWVB signal amplitudes.

On the Importance of Solar Eclipse Geometry in the Interpretation of Ionospheric Observations

NASA Astrophysics Data System (ADS)

Stankov, S.; Verhulst, T. G. W.

2017-12-01

A reliable interpretation of solar eclipse effects on the geospace environment, and on the ionosphere in particular, necessitates a careful consideration of the so-called eclipse geometry. A solar eclipse is a relatively rare astronomical phenomenon, which geometry is rather complex, specific for each event, and fast changing in time. The standard, most popular way to look at the eclipse geometry is via the two-dimensional representation (map) of the solar obscuration on the Earth's surface, in which the path of eclipse totality is drawn together with isolines of the gradually-decreasing eclipse magnitude farther away from this path. Such "surface maps" are widely used to readily explain some of the solar eclipse effects including, for example, the well-known decrease in total ionisation (due to the substantial decrease in solar irradiation), usually presented by the popular and easy to understand ionospheric characteristic of Total Electron Content (TEC). However, many other effects, especially those taking place at higher altitudes, cannot be explained in this fashion. Instead, a complete, four-dimensional (4D) description of the umbra (and penumbra), would be required. This presentation will address the issue of eclipse geometry effects on various ionospheric observations carried out during the total solar eclipse of August 21, 2017. In particular, GPS-based TEC and ionosonde measurements will be analysed and the eclipse effects on the ionosphere will be interpreted with respect to the actual eclipse geometry at ionospheric heights. Whenever possible, a comparison will be made with results from previous events, such as the ones from March 20, 2015 and October 3, 2005.

Eclipse prediction on the ancient Greek astronomical calculating machine known as the Antikythera Mechanism.

PubMed

Freeth, Tony

2014-01-01

The ancient Greek astronomical calculating machine, known as the Antikythera Mechanism, predicted eclipses, based on the 223-lunar month Saros cycle. Eclipses are indicated on a four-turn spiral Saros Dial by glyphs, which describe type and time of eclipse and include alphabetical index letters, referring to solar eclipse inscriptions. These include Index Letter Groups, describing shared eclipse characteristics. The grouping and ordering of the index letters, the organization of the inscriptions and the eclipse times have previously been unsolved. A new reading and interpretation of data from the back plate of the Antikythera Mechanism, including the glyphs, the index letters and the eclipse inscriptions, has resulted in substantial changes to previously published work. Based on these new readings, two arithmetical models are presented here that explain the complete eclipse prediction scheme. The first model solves the glyph distribution, the grouping and anomalous ordering of the index letters and the structure of the inscriptions. It also implies the existence of lost lunar eclipse inscriptions. The second model closely matches the glyph times and explains the four-turn spiral of the Saros Dial. Together, these models imply a surprisingly early epoch for the Antikythera Mechanism. The ancient Greeks built a machine that can predict, for many years ahead, not only eclipses but also a remarkable array of their characteristics, such as directions of obscuration, magnitude, colour, angular diameter of the Moon, relationship with the Moon's node and eclipse time. It was not entirely accurate, but it was an astonishing achievement for its era.

Many persons who drink excessively remain unidentified and do not receive interventions. Screening and intervention using the World Wide Web could make such services more accessible and therefore more widely used. To evaluate the use of a novel alcohol screening and brief intervention Web site. A Web site was developed, posted, and its use was evaluated. We analyzed a sample of visitors who completed alcohol screening over a 14-month period to describe their alcohol use, and their use of portions of the Web site that provide information and referral resources. The Internet. Web site visitors, with a focus on visitors who completed an alcohol-screening questionnaire about their own drinking. Brief intervention via the Web site, consisting mainly of feedback, advice, and a menu of change options and referral information. Self-reported drinking amounts and alcohol screening test scores, and utilization of Web site components. Visitors completed online alcohol screening questionnaires at a rate of 50,711/year of 115,925 visitors/year. In a 14-month period, 39,842 adults completed the questionnaire about their own drinking habits; 66% were men, 90% reported drinking hazardous amounts (per occasion or typical weekly amounts), 88% reported binge (per occasion) drinking, and 55% reported typically exceeding weekly risky drinking limits. Most (65%) had alcohol screening test results (AUDIT > or = 8) consistent with alcohol abuse or dependence; similar proportions of women and men were hazardous drinkers. One-fifth of visitors visited portions of the Web site that provided additional information about alcohol use and referrals. Visitors with possible alcohol abuse or dependence were more likely than those without these disorders to visit a part of the Web site designed for those seeking additional help (33% vs. 8%, P < 0.0001). A well-publicized, easily accessible, research-based screening and intervention Web site can attract many users, most of whom are drinking excessively, and many of whom avail themselves of referral information after receiving individualized feedback.

The database stores this expertise as choreographed and interlinked multimedia entities including text, imagery, interactive questions, and audio. Case-based presentations or thematic lectures can be authored locally, previewed locally within a web browser, then uploaded at will as packaged knowledge objects to an educator's (or department's) personal web site housed within a virtual server architecture. This architecture can host an unlimited number of unique educational web sites for individuals or departments in need of such service. Each virtual site's content is stored within that site's protected back-end database connected to Internet Information Server (Microsoft Corp, Redmond WA) using a suite of Active Server Page (ASP) modules that incorporate Microsoft's Active Data Objects (ADO) technology. Each person's or department's electronic teaching material appears as an independent web site with different levels of access--controlled by a username-password strategy--for teachers and students. There is essentially no static hypertext markup language (HTML). Rather, all pages displayed for a given site are rendered dynamically from case-based or thematic content that is fetched from that virtual site's database. The dynamically rendered HTML is displayed within a web browser in a Socratic fashion that can assess the recipient's current fund of knowledge while providing instantaneous user-specific feedback. Each site is emblazoned with the logo and identification of the participating institution. Individuals with teacher-level access can use a web browser to upload new content as well as manage content already stored on their virtual site. Each virtual site stores, collates, and scores participants' responses to the interactive questions posed on line. This virtual web site strategy empowers the educator with an end-to-end solution for creating interactive educational content and hosting that content within the educator's personalized and protected educational site on the world wide web, thus providing a valuable outlet that can magnify the impact of his or her talents and contributions.

Cross-sectional survey. The objective of this study was to investigate the authorship, content, and quality of information available to the public on the Internet pertaining to the cervical artificial disc replacement device. The Internet is widely used by patients as an educational tool for health care information. In addition, the Internet is used as a medium for direct-to-consumer marketing. Increasing interest in cervical artificial disc replacement has led to the emergence of numerous Web sites offering information about this procedure. It is thought that patients can be influenced by information found on the Internet. A cross section of Web sites accessible to the general public was surveyed. Three commonly used search engines were used to locate 150 (50/search engine) Web sites providing information about the cervical artificial disc replacement. Each Web site was evaluated with regard to authorship and content. Fifty-three percent of the Web sites reviewed were authorized by a private physician group, 4% by an academic physician group, 13% by industry, 16% were news reports, and 14% were not otherwise categorized. Sixty-five percent of Web sites offered a mechanism for direct contact and 19% provided clear patient eligibility criteria. Benefits were expressed in 80% of Web sites, whereas associated risks were described in 35% or less. European experiences were noted in 17% of Web sites, whereas only 9% of Web sites detailed the current US experience. CONCLUSION.: The results of this study demonstrate that much of the content of the Internet-derived information pertaining to the cervical artificial disc replacement is for marketing purposes and may not represent unbiased information. Until we can confirm the content on a Web site to be accurate, patients should be cautioned when using the Internet as a source for health care information related to cervical disc replacement.

The Dutch Lung Cancer Information Centre launched the Web site www.longkanker.info in November 2003. The purpose of this article is to describe the launching of the Web site, its development, the type of visitors to the Web site, what they were looking for, and whether they found what they requested. Supervised by a panel (pulmonologists, patients, communication specialists), a large amount of material about lung cancer has been collected and edited into accessible language by health care providers, and the Web site has been divided into special categories following the different stages that lung cancer patients, relatives, and health care providers go through during the illness. The Web site is updated regularly. Search engines have been used to check the position of the Web site as a "hit." Pulmonologists have been informed about the founding of the Web site, and all lung cancer outpatient clinics in The Netherlands have received posters, folders, and cards to inform their patients. Visitor numbers, page views, and visitor numbers per page view have been registered continuously. Visitor satisfaction polls were placed in the second half of 2004 and the second half of 2005. The Web site appeared as first hit when using search engines immediately after launching it. Half of the visitors came to the Web site via search engines or links found at other sites. The number of visitors started at 4600 in the first month, doubled in the next months, and reached 18,000 per month 2 years after its launch. The number of visited pages increased to 87,000 per month, with an average number of five pages per visitor. Thirty percent of the visitors return within the same month. The most popular pages are interactive pages with the overview of all questions to "ask the doctor" at the top with forum messages, survival figures of all form of lung cancer, and information about the disease. The first satisfaction poll obtained 650 respondents and the second 382. The visitors to the Web site are caregivers (57%), patients (8%), and others (students, people fearing lung cancer). Of the visitors, 895 found what they were looking for, and the satisfaction is the highest among nurses and caregivers (91% and 95%, respectively) and the lowest among physicians and patients (85% and 83%). Given the number of visitors to the lung cancer Web site, it can be concluded that there is a great need for additional information among patients and caregivers. The launched Web site www.longkanker.info has reached its goal of providing a dependable source of information about lung cancer and satisfying its visitors.

Guidelines for medical and health information sites on the internet: principles governing AMA web sites. American Medical Association.

Access to medical information via the Internet has the potential to speed the transformation of the patient-physician relationship from that of physician authority ministering advice and treatment to that of shared decision making between patient and physician. However, barriers impeding this transformation include wide variations in quality of content on the Web, potential for commercial interests to influence online content, and uncertain preservation of personal privacy. To address these issues, the American Medical Association (AMA) has developed principles to guide development and posting of Web site content, govern acquisition and posting of online advertising and sponsorship, ensure site visitors' and patients' rights to privacy and confidentiality, and provide effective and secure means of e-commerce. While these guidelines were developed for the AMA Web sites and visitors to these sites, they also may be useful to other providers and users of medical information on the Web. These principles have been developed with the understanding that they will require frequent revision to keep pace with evolving technology and practices on the Internet. The AMA encourages review and feedback from readers, Web site visitors, policymakers, and all others interested in providing reliable quality information via the Web.

Cognitive aspects of ancient Maya eclipse theory.

NASA Astrophysics Data System (ADS)

Closs, M. P.

This paper is concerned with determining the nature of eclipse phenomena as it was perceived by the ancient Maya. It approaches the problem by considering the linguistic information pertaining to eclipses and by exploring the traditional beliefs associated with the occurrence of eclipses among the postconquest Maya. These data yield a model of a native eclipse theory which is compatible with hieroglyphic and iconographic materials pertaining to the ancient Maya.

The "Great American Eclipse" – the total solar eclipse visible across the USA on 21 August 2017 – resulted in some notable eclipse images and videos high in educational and scientific value. Some of the images that were selected to appear on the Astronomy Picture of the Day (APOD) website are shown in high resolution accompanied by educational descriptions. The questions of whether this eclipse was the most viewed and the most photographed event of any type in human history will be discussed. People are invited to come by and share their own eclipse images and stories.

On Social e-Learning

Kim, Won; Jeong, Ok-Ran

Social Web sites include social networking sites and social media sites. They make it possible for people to share user-created contents online and to interact and stay connected with their online people networks. The social features of social Web sites, appropriately adapted, can help turn e-learning into social e-learning and make e-learning significantly more effective. In this paper, we develop requirements for social e-learning systems. They include incorporating the many of the social features of social Web sites, accounting for all key stakeholders and learning subjects, and curbing various types of misuses by people. We also examine the capabilities of representative social e-learning Web sites that are available today.

Produce and Consume Linked Data with Drupal!

NASA Astrophysics Data System (ADS)

Corlosquet, Stéphane; Delbru, Renaud; Clark, Tim; Polleres, Axel; Decker, Stefan

Currently a large number of Web sites are driven by Content Management Systems (CMS) which manage textual and multimedia content but also - inherently - carry valuable information about a site's structure and content model. Exposing this structured information to the Web of Data has so far required considerable expertise in RDF and OWL modelling and additional programming effort. In this paper we tackle one of the most popular CMS: Drupal. We enable site administrators to export their site content model and data to the Web of Data without requiring extensive knowledge on Semantic Web technologies. Our modules create RDFa annotations and - optionally - a SPARQL endpoint for any Drupal site out of the box. Likewise, we add the means to map the site data to existing ontologies on the Web with a search interface to find commonly used ontology terms. We also allow a Drupal site administrator to include existing RDF data from remote SPARQL endpoints on the Web in the site. When brought together, these features allow networked RDF Drupal sites that reuse and enrich Linked Data. We finally discuss the adoption of our modules and report on a use case in the biomedical field and the current status of its deployment.

2002-01-01

Several methods are available to evaluate and compare medical journals. The most popular is the journal Impact Factor, derived from averaging counts of citations to articles. Ingwersen adapted this method to assess the attractiveness of Web sites, defining the external Web Impact Factor (WIF) to be the number of external pages containing a link to a given Web site. This paper applies the WIF to 43 medical informatics societies' Web sites using advanced search engine queries to obtain the necessary link counts. The WIF was compared to the number of publications available in the Medline bibliographic database in medical informatics in these 43 countries. Between these two metrics, the observed Pearson correlation was 0.952 (p < 0.01) and the Spearman rank correlation was 0.548 (p < 0.01) showing in both cases a positive and strong significant correlation. The WIF of medicalm informatics society's Web site is statistically related to national productivity and discrepancies can be used to indicate countries where there are either weak medical informatics associations, or ones that do not make optimal use of the Web.

Use of a secure Internet Web site for collaborative medical research.

PubMed

Marshall, W W; Haley, R W

2000-10-11

Researchers who collaborate on clinical research studies from diffuse locations need a convenient, inexpensive, secure way to record and manage data. The Internet, with its World Wide Web, provides a vast network that enables researchers with diverse types of computers and operating systems anywhere in the world to log data through a common interface. Development of a Web site for scientific data collection can be organized into 10 steps, including planning the scientific database, choosing a database management software system, setting up database tables for each collaborator's variables, developing the Web site's screen layout, choosing a middleware software system to tie the database software to the Web site interface, embedding data editing and calculation routines, setting up the database on the central server computer, obtaining a unique Internet address and name for the Web site, applying security measures to the site, and training staff who enter data. Ensuring the security of an Internet database requires limiting the number of people who have access to the server, setting up the server on a stand-alone computer, requiring user-name and password authentication for server and Web site access, installing a firewall computer to prevent break-ins and block bogus information from reaching the server, verifying the identity of the server and client computers with certification from a certificate authority, encrypting information sent between server and client computers to avoid eavesdropping, establishing audit trails to record all accesses into the Web site, and educating Web site users about security techniques. When these measures are carefully undertaken, in our experience, information for scientific studies can be collected and maintained on Internet databases more efficiently and securely than through conventional systems of paper records protected by filing cabinets and locked doors.

2016-01-01

Increasing numbers of training physicians are using the Internet to gather information about graduate medical education programs. The content and accessibility of web sites that provide this information have been demonstrated to influence applicants' decisions. Assessments of orthopedic fellowship web sites including sports medicine, pediatrics, hand and spine have found varying degrees of accessibility and material. The purpose of this study was to evaluate the accessibility and content of the American Shoulder and Elbow Surgeons (ASES) fellowship web sites (SEFWs). A complete list of ASES programs was obtained from a database on the ASES web site. The accessibility of each SEFWs was assessed by the existence of a functioning link found in the database and through Google®. Then, the following content areas of each SEFWs were evaluated: fellow education, faculty/previous fellow information, and recruitment. At the time of the study, 17 of the 28 (60.7%) ASES programs had web sites accessible through Google®, and only five (17.9%) had functioning links in the ASES database. Nine programs lacked a web site. Concerning web site content, the majority of SEFWs contained information regarding research opportunities, research requirements, case descriptions, meetings and conferences, teaching responsibilities, attending faculty, the application process, and a program description. Fewer than half of the SEFWs provided information regarding rotation schedules, current fellows, previous fellows, on-call expectations, journal clubs, medical school of current fellows, residency of current fellows, employment of previous fellows, current research, and previous research. A large portion of ASES fellowship programs lacked functioning web sites, and even fewer provided functioning links through the ASES database. Valuable information for potential applicants was largely inadequate across present SEFWs.

Characteristics associated with use of public and private web sites as sources of health care information: results from a national survey.

PubMed

Miller, Edward Alan; West, Darrell M

2007-03-01

We sought to determine the frequency with which Americans access health information from governmental (public sector) and nongovernmental (private sector) web sites and to identify similarities and differences in the characteristics associated with use of each type. Data derive from 928 individuals who responded to a November 2005 national survey. In addition to forms of health communication, we asked about age, gender, race, income, education, insurance, lifestyle, residence, satisfaction, literacy, and health. We report the extent of web site use stratified by sponsorship type-public and private. We also use chi tests to examine bivariate associations. Logistic regression and multiple imputation of missing data were used to examine the correlates of use in a multivariate context. More than twice as many respondents visited private web sites (29.6%) than public web sites (13.2%). However, just 23.6% and 18.9% of private and public web site visitors, respectively, reported doing so once a month or more. Both public and private web site visitors were more likely to be better-educated respondents (odds ratio [OR]=0.83, OR=1.57) reporting greater concerns about health care access (OR=1.28, OR=1.20) than nonvisitors. Younger individuals (OR=0.83) living in urban areas (OR=1.59) with stronger health literacy (OR=1.24) and reporting greater concerns about health care affordability (OR=1.59) were more likely to visit privately sponsored web sites but nonpublicly sponsored ones. Relatively low utilization levels necessitate a concerted effort to improve the quality, accessibility, and relevance of Internet health information. Efforts to close the digital divide must recognize differences in user characteristics across governmental and nongovernmental web site providers.

Non-visual Web Browsing: Beyond Web Accessibility

PubMed Central

Ramakrishnan, I.V.; Ashok, Vikas

2017-01-01

People with vision impairments typically use screen readers to browse the Web. To facilitate non-visual browsing, web sites must be made accessible to screen readers, i.e., all the visible elements in the web site must be readable by the screen reader. But even if web sites are accessible, screen-reader users may not find them easy to use and/or easy to navigate. For example, they may not be able to locate the desired information without having to listen to a lot of irrelevant contents. These issues go beyond web accessibility and directly impact web usability. Several techniques have been reported in the accessibility literature for making the Web usable for screen reading. This paper is a review of these techniques. Interestingly, the review reveals that understanding the semantics of the web content is the overarching theme that drives these techniques for improving web usability. PMID:29202137

Aims: We aim to find more eclipsing multiple systems and obtain their parameters, thus increasing our understanding of multiple systems. Methods: The extraneous eclipses on the Kepler binary light curves indicating extraneous bodies were searched. The binary light curves were analyzed using the binary model, and the extraneous eclipses were studied on their periodicity and shape changes. Results: Three binaries with extraneous eclipses on the binary light curves were found and studied based on the Kepler observations. The object KIC 5255552 is an eclipsing triple system with a fast changing inner binary and an outer companion uncovered by three groups of extraneous eclipses of 862.1(±0.1) d period. The KIC 10091110 is suggested to be a double eclipsing binary system with several possible extraordinary coincidences: the two binaries share similar extremely small mass ratios (0.060(13) and 0.0564(18)), similar mean primary densities (0.3264(42) ρ⊙ and 0.3019(28) ρ⊙), and, most notably, the ratio of the two binaries' periods is very close to integer 2 (8.5303353/4.2185174 = 2.022). The KIC 11495766 is a probable triple system with a 120.73 d period binary and (at least) one non-eclipse companion. Furthermore, very close to it in the celestial sphere, there is a blended background stellar binary of 8.3404432 d period. A first list of 25 eclipsing multiple candidates is presented, with the hope that it will be beneficial for study of eclipsing multiples.

The total solar eclipse that occurred over the Arctic region on 20 March 2015 was seen as a partial eclipse over much of Europe. Observations of this eclipse were used to investigate the high time resolution (1 min) decay and recovery of the Earth's ionospheric E-region above the ionospheric monitoring station in Chilton, UK. At the altitude of this region (100 km), the maximum phase of the eclipse was 88.88% obscuration of the photosphere occurring at 9:29:41.5 UT. In comparison, the ionospheric response revealed a maximum obscuration of 66% (leaving a fraction, Φ, of uneclipsed radiation of 34±4%) occurring at 9:29 UT. The eclipse was re-created using data from the Solar Dynamics Observatory to estimate the fraction of radiation incident on the Earth's atmosphere throughout the eclipse from nine different emission wavelengths in the extreme ultraviolet (EUV) and X-ray spectrum. These emissions, having varying spatial distributions, were each obscured differently during the eclipse. Those wavelengths associated with coronal emissions (94, 211 and 335 Å) most closely reproduced the time varying fraction of unobscured radiation observed in the ionosphere. These results could enable historic ionospheric eclipse measurements to be interpreted in terms of the distribution of EUV and X-ray emissions on the solar disc.This article is part of the themed issue 'Atmospheric effects of solar eclipses stimulated by the 2015 UK eclipse'. © 2016 The Author(s).

Health and medication information resources on the World Wide Web.

Grossman, Sara; Zerilli, Tina

2013-04-01

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

Public Education and Outreach for Observing Solar Eclipses and Transits

NASA Astrophysics Data System (ADS)

Pasachoff, Jay M.

2015-08-01

The general public is often very interested in observing solar eclipses, with widespread attention from newspapers and other sources often available only days before the events. Recently, the 2012 eclipse's partial phases in Australia and the 2015 eclipse's partial phases throughout Europe as well as western Asia and northern Africa, were widely viewed. The 21 August 2017 eclipse, whose totality will sweep across the Continental United States from northwest to southeast, will have partial phases visible throughout the U.S., Canada, Mexico, Central America, and into South America. The 2019 and 2020 partial phases of total eclipses will be visible throughout South America, and partial phases from annular eclipses will be visible from other parts of the world. The 9 May 2016 transit of Mercury will be best visible from the Western Hemisphere, Europe, and Africa. Many myths and misunderstandings exist about the safety of observing partial phases, and it is our responsibility as astronomers and educators to transmit accurate information and to attempt the widest possible distribution of such information. The Working Group on Public Education at Eclipses and Transits, formerly of Commission 46 on Education and Development and now of New Commission 11, tries to coordinate the distribution of information. In collaboration with the Solar Division's Working Group on Solar Eclipses, their website at http://eclipses.info is a one-stop shop for accurate information on how to observe eclipses, why it is interesting to do so, where they will be visible (with links to online maps and weather statistics), and how encouraging students to observe eclipses can be inspirational for them, perhaps even leading them to realize that the Universe can be understood and therefore renewing the strength of their studies. Links to information about transits of Mercury and Venus are also included.

We evaluated the quality of Internet information available for femoroacetabular impingement (FAI). Four popular search engines were used to collect 100 Web sites containing information on FAI. Web sites were evaluated based on authorship, various content criteria, and the presence of Health On the Net Code of Conduct (HONcode) certification. By use of a novel evaluation system for quality, Web sites were also classified as excellent, high, moderate, poor, or inadequate and were subsequently analyzed. Web sites were evaluated as a group, followed by authorship type, by HONcode certification, and by quality level. Of the Web sites, 73 offered the ability to contact the author, 91 offered a considerable explanation of FAI, 54 provided surgical treatment options, 58 offered nonsurgical treatment options, 27 discussed possible complications, 11 discussed eligibility criteria, 31 discussed rehabilitation, 67 discussed a differential diagnosis, and 48 included peer-reviewed citations. We categorized 40 Web sites as academic, 33 as private, 9 as industry, 9 as public education, and 9 as blogs. Our novel quality evaluation system classified 16 Web sites as excellent, 18 as high, 17 as moderate, 18 as poor, and 31 as inadequate. Only 8% of all evaluated Web sites contained HONcode certification. We found that the quality of information available on the Internet about FAI was dramatically variable. A significantly large proportion of Web sites were from academic sources, but this did not necessarily indicate higher quality. Sites with HONcode certification showed as much variability in quality as noncertified sites. This study increases clinician competence in the available Internet information about FAI and helps them to confidently guide patients to formulate appropriate medical decisions based on high-quality information.

Kinzie, Mable B.; Cohn, Wendy F.; Julian, Marti F.; Knaus, William A.

2002-01-01

As the Internet continues to grow as a delivery medium for health information, the design of effective Web sites becomes increasingly important. In this paper, the authors provide an overview of one effective model for Web site design, a user-centered process that includes techniques for needs assessment, goal/task analysis, user interface design, and rapid prototyping. They detail how this approach was employed to design a family health history Web site, Health Heritage . This Web site helps patients record and maintain their family health histories in a secure, confidential manner. It also supports primary care physicians through analysis of health histories, identification of potential risks, and provision of health care recommendations. Visual examples of the design process are provided to show how the use of this model resulted in an easy-to-use Web site that is likely to meet user needs. The model is effective across diverse content arenas and is appropriate for applications in varied media. PMID:12087113

In recent years, due to the global warming and global climate anomaly, more and more disasters appear such as flood and debris flow. The disasters always cause loss of life and property. However, the cross-aged invention, smart phone, makes our life more conveniently for delivering lots of information instantly. This study uses Eclipse as the development platform, and designs the urban disaster information mobile Application (APP) which is for debris flow and flood in Taipei city area. In this study, an urban disaster information APP, Taipei Let You Know, has successfully developed under android development environment, combined disaster indicators and the warming value of disaster. In order to ameliorate official information delay problem, this APP not only shows official information, but also offers a WEB 2.0 platform for public users to upload all disaster information instantly. As the result, the losses of life and property can decrease, and the disaster information delivery can be faster and more accurate by utilizing this APP in the future.

Solar Eclipses and the International Year of Astronomy

Solar eclipses capture the attention of millions of people in the countries from which they are visible and provide a major opportunity for public education, in addition to the scientific research and student training that they provide. The 2009 International Year of Astronomy began with an annular eclipse visible from Indonesia on 26 January, with partial phases visible also in other parts of southeast Asia. On 22 July, a major and unusually long total solar eclipse will begin at dawn in India and travel across China, with almost six minutes of totality visible near Shanghai and somewhat more visible from Japanese islands and from ships at sea in the Pacific. Partial phases will be visible from most of eastern Asia, from mid-Sumatra and Borneo northward to mid-Siberia. Eclipse activities include many scientific expeditions and much ecotourism to Shanghai, Hangzhou, and vicinity. My review article on "Eclipses as an Astrophysical Laboratory" will appear in Nature as part of their IYA coverage. Our planetarium presented teacher workshops and we made a film about solar research. Several new books about the corona or eclipses are appearing or have appeared. Many articles are appearing in astronomy magazines and other outlets. Eclipse interviews are appearing on the Planetary Society's podcast "365 Days of Astronomy" and on National Geographic Radio. Information about the eclipse and safe observation of the partial phases are available at http://www.eclipses.info, the Website of the International Astronomical Union's Working Group on Solar Eclipses and of its Program Group on Public Education at the Times of Eclipses of its Commission on Education and Development. The Williams College Expedition to the 2009 Eclipse in the mountains near Hangzhou, China, is supported in part by a grant from the Committee for Research and Exploration of the National Geographic Society. E/PO workshops were supported by NASA.

In 1998 the tobacco industry was released of claims that provided monetary relief for states. A significant expansion of tobacco control activity in many states created a need to develop local capacity. Technical assistance and training for new and experienced staff became a significant challenge for tobacco control leadership. In Colorado, this challenge was addressed in part through the development of a technical assistance and training Web site designed for local tobacco control staff and coalition members. Researchers, technical Web site development specialists, state health agency, and state tobacco control coalition staff collaborated to develop, promote, and test the efficacy of this Web site. The work group embodied a range of skills including tobacco control, Web site technical development, marketing, training, and project management. Persistent marketing, updating of Web site content, and institutionalizing it as a principal source of information and training were key to use by community coalition members.

2018-04-01

It has long been recognized that during solar eclipses, the ionosphere-thermosphere system changes greatly within the eclipse shadow, due to the rapid reduction of solar irradiation. However, the concept that a solar eclipse impacts polar ionosphere behavior and dynamics as well as magnetosphere-ionosphere coupling has not been appreciated. In this study, we investigate the potential impact of the 21 August 2017 solar eclipse on the polar tongue of ionization (TOI) using a high-resolution, coupled ionosphere-thermosphere-electrodynamics model. The reduction of electron densities by the eclipse in the middle latitude TOI source region leads to a suppressed TOI in the polar region. The TOI suppression occurred when the solar eclipse moved into the afternoon sector. The Global Positioning System total electron content observations show similar tendency of polar region total electron content suppression. This study reveals that a solar eclipse occurring at middle latitudes may have significant influences on the polar ionosphere and magnetosphere-ionosphere coupling.

Sorong is located outside the narrow path of total solar eclipse on March 9th, 2016. The predicted obscuration of the sun was 94.2%. The public outreach to anticipate the solar eclipse was intended to educate students in junior and senior high school in Sorong Regency. Some of them are located in the remote area where the educational materials are difficult to find. The public outreach is unique, since it was run by the local person who is student of physics education. The student has both the ability to explain the solar eclipse phenomenon and able to adapt to knowledge level of students. The materials that were given to the schools are brochure and the eclipse glasses. Beside solar eclipse lectures in class, the pinhole workshop and observation practice were held. The limited materials and resources were faced during the public outreach. However, the enthusiasm was shown by the students and teachers. At least one of the schools held the solar eclipse observation on the day of the eclipse.

Vaccines and Internet: characteristics of the vaccine safety net web sites and suggested improvements.

2008-12-09

The Internet contains a large amount of useful information on many subjects, but also information of doubtful quality. To help identify Web sites on vaccine safety that fulfil good practice, the Global Advisory Committee on Vaccine Safety of the World Health Organization (WHO) has published criteria to which sites should adhere and a listing of Web sites that fulfil them. There are no studies describing the common attributes of these sites. To examine the attributes, design characteristics and resources of Web sites belonging to the Vaccine Safety Net (VSN) of the WHO. A cross-sectional, descriptive observational study using an evaluation questionnaire was carried out applied to the VSN web sites listed in March-April 2007. Twenty-six Web sites accredited by the VSN by April 2007 were analysed. With respect to design and quality, all sites contained information about the site manager. Postal and Email addresses were available for 84.6% of the sites. About privacy and personal data processing, 73.1% of sites specified the data protection procedure used and stated that data were not sold or passed third parties. The most-used language was English (76.9%). 96.3% of sites had links to other pro-vaccination sites and 19.2% provided the addresses of vaccination centres. 63.6% of webs were aimed at general public and health care workers but there was no clear separation of documents or different entry routes. With respect to information on vaccine safety, 84.6% of sites had information on adverse effects. In the general information section, 92.3% of sites had a new developments section. Some sites had multiple sources of financing and in 57% of sites, the financing was public. The most-important plus factors found were the transparency of financing, the lack of links to the pharmaceutical industry, the transparency of site management and responsibility and the proven scientific quality and constant updating of contents.

The battle for hearts and minds: who is communicating most effectively with the cosmetic marketplace?

Cosmetic surgery, historically the purview of plastic surgeons, has in recent years seen an influx of practitioners from other fields of training. Many of these new providers are savvy in marketing and public relations and are beginning to control a surprisingly large amount of cosmetic patient care. The purpose of this study is to measure the amount of traffic being attracted to the Web sites of individual practitioners and organizations vying for cosmetic patients. This study investigates the trends of the past 12 months and identifies changes of special concern to plastic surgeons. The Web sites of 1307 cosmetic providers were monitored over a year's time. The Web activity of two million individuals whose computers were loaded with a self-reporting software package was recorded and analyzed. The Web sites were analyzed according to the specialty training of the site owner and total unique visits per month were tallied for the most prominent specialties. The dominant Web sites were closely scrutinized and the Web optimization strategies of each were also examined. There is a tremendous amount of Web activity surrounding cosmetic procedures and the amount of traffic on the most popular sites is continuing to grow. Also, a large sum of money is being expended to channel Web traffic, with sums in the thousands of dollars being spent daily by top Web sites. Overall in the past year, the private Web sites of plastic surgeons have increased their reach by 10%, growing from 200,000 to approximately 220,000 unique visitors monthly. Plastic surgery remains the specialty with the largest number of Web visitors per month. However, when combined, the private Web sites of all other providers of aesthetic services have significantly outpaced plastic surgery's growth. The traffic going to non-plastic surgeons has grown by 50% (200,000 visitors per month in September 2008 to 300,000 visitors monthly in September 2009). For providers of aesthetic services, communication with the public is of utmost importance. The Web has become the single most important information resource for consumers because of easy access. Plastic surgeons are facing significant competition for the attention of potential patients, with increasingly sophisticated Web sites and listing services being set up by independent parties. It is important for plastic surgeons to become familiar with the available Internet tools for communication with potential patients and to aggressively utilize these tools for effective practice building.

Translating access into utilization: lessons from the design and evaluation of a health insurance Web site to promote reproductive health care for young women in Massachusetts.

PubMed

Janiak, Elizabeth; Rhodes, Elizabeth; Foster, Angel M

2013-12-01

Following state-level health care reform in Massachusetts, young women reported confusion over coverage of contraception and other sexual and reproductive health services under newly available health insurance products. To address this gap, a plain-language Web site titled "My Little Black Book for Sexual Health" was developed by a statewide network of reproductive health stakeholders. The purpose of this evaluation was to assess the health literacy demands and usability of the site among its target audience, women ages 18-26 years. We performed an evaluation of the literacy demands of the Web site's written content and tested the Web site's usability in a health communications laboratory. Participants found the Web site visually appealing and its overall design concept accessible. However, the Web site's literacy demands were high, and all participants encountered problems navigating through the Web site. Following this evaluation, the Web site was modified to be more usable and more comprehensible to women of all health literacy levels. To avail themselves of sexual and reproductive health services newly available under expanded health insurance coverage, young women require customized educational resources that are rigorously evaluated to ensure accessibility. To maximize utilization of reproductive health services under expanded health insurance coverage, US women require customized educational resources commensurate with their literacy skills. The application of established research methods from the field of health communications will enable advocates to evaluate and adapt these resources to best serve their targeted audiences. © 2013.

The 1982 ultraviolet eclipse of the symbiotic binary AR Pav

NASA Technical Reports Server (NTRS)

Hutchings, J. B.; Cowley, A. P.; Ake, T. B.; Imhoff, C. L.

1983-01-01

Observations with the International Ultraviolet Explorer (IUE) of the symbiotic binary AR Pav through its 1982 eclipse show that the hot star is not eclipsed. The hot star is associated with an extended region of continuum emission which is partially eclipsed. The eclipsed radiation is hotter near to its center, with a maximum temperature of about 9000 K. The uneclipsed flux is hotter than this. UV emission lines are not measurably eclipsed and presumably arise in a much larger region than the continuum. These data provide new constraints on models of the system but also are apparently in contradiction to those based on ground-based data.

With support from the Moore Foundation, Google, the Research Corporation, and NASA, we were able to distribute about 2.1 million eclipse glasses and an extensive booklet of eclipse information and outreach suggestions to 7,100 public libraries throughout the nation. It appears that this project was the single largest program to provide glasses and eclipse information to the public in the U.S. The project using (and significantly enlarged) the existing STARNet network of libraries set up and maintained by the Space Science Institute. We were able to get glasses to a diverse set of institutions, including urban, rural, Native American, small town and large city libraries. In this poster, we will summarize the history of the project, the various components and how they worked together, and the results of a post survey of the librarians, which provided numbers, photographs, and impressions from the many libraries and their patrons. A map of the libraries involved is at www.starnetlibraries.org/2017eclipse/. The booklet of information that was sent to help train librarians in eclipse science and eclipse outreach can still be downloaded free at: http://www.starnetlibraries.org/EclipseGuide/.”

Little cigars, big cigars: omissions and commissions of harm and harm reduction information on the Internet.

PubMed

Dollar, Katherine M; Mix, Jacqueline M; Kozlowski, Lynn T

2008-05-01

We conducted a comparative analysis of "harm," "harm reduction," and "little cigar" information about cigars on 10 major English-language health Web sites. The sites were from governmental and nongovernmental organizations based in seven different countries and included "harm" and "harm reduction" information, discussions of little cigars, quantitative estimates of health risks, and qualifying behavioral characteristics (inhalation, number per day). Of the 10 Web sites, 7 offered statements explicitly indicating that cigars may be safer than cigarettes. None of the Web sites reviewed described that little cigars are likely as dangerous as cigarettes. Some Web sites provided quantitative estimates of health risks and extensive discussions of qualifying factors. Reading grade levels were higher than desirable. Extensive and complex information on the reduced risks of cigars compared with cigarettes is available on Web sites affiliated with prominent health organizations. Yet these sites fail to warn consumers that popular cigarette-like little cigars and cigarillos are likely to be just as dangerous as cigarettes, even for those who have never smoked cigarettes. Improvement of these Web sites is urgently needed to provide the public with high-quality health information.

Solar Eclipses Observed from Antarctica

NASA Astrophysics Data System (ADS)

Pasachoff, Jay M.

2013-01-01

Aspects of the solar corona are still best observed during totality of solar eclipses, and other high-resolution observations of coronal active regions can be observed with radio telescopes by differentiation of occultation observations, as we did with the Jansky Very Large Array for the annular solar eclipse of 2012 May 20 in the US. Totality crossing Antarctica included the eclipse of 2003 November 23, and will next occur on 2021 December 4; annularity crossing Antarctica included the eclipse of 2008 February 7, and will next occur on 2014 April 29. Partial phases as high as 87% coverage were visible and were imaged in Antarctica on 2011 November 25, and in addition to partial phases of the total and annular eclipses listed above, partial phases were visible in Antarctica on 2001 July 2011, 2002 December 4, 2004 April 19, 2006 September 22, 2007 September 11, and 2009 January 26, and will be visible on 2015 September 13, 2016 September 1, 2017 February 26, 2018 February 15, and 2020 December 14. On behalf of the Working Group on Solar Eclipses of the IAU, the poster showed the solar eclipses visible from Antarctica and this article shows a subset (see www.eclipses.info for the full set). A variety of investigations of the Sun and of the response of the terrestrial atmosphere and ionosphere to the abrupt solar cutoff can be carried out at the future eclipses, making the Antarctic observations scientifically useful.

Ionospheric effects over Europe during the solar eclipse on 20 March 2015

NASA Astrophysics Data System (ADS)

Hoque, Mainul; Jakowski, Norbert; Berdermann, Jens

2017-04-01

A total solar eclipse occurred on March 20, 2015 moving from the North-West Europe towards the North-East. Due to strong solar radiation changes dynamic processes were initiated in the atmosphere and ionosphere causing a measurable impact e.g. on the temperature and ionization during the eclipse. We analyzed the 20 March 2015 solar eclipse effects on the ionospheric structure over Europe using multi-sensor observations such as vertical sounding (VS) and Global Positioning System (GPS) measurements. Whereas the VS measurements are used to provide peak electron density information at the ionospheric F2, F1 and E layers over selected ionosonde stations, a dense network of GPS stations is used to provide high spatial resolution of the total electron content (TEC) estimates over Europe. We reconstructed the TEC maps with 5 minutes time resolution and thus investigated the original TEC maps and differential TEC maps obtained by subtracting 27 days medians from the actual TEC map values on 20 March 2015. By combining VS and GPS measurements the equivalent slab thickness has been estimated over several ionosonde stations to get information how the shape of the vertical electron density profile changes during the eclipse. The analysis of the solar eclipse on 20 March 2015 presented here will contribute to understand the ionospheric response on solar eclipses occurring at different latitudes. The observations indicate that a number of competitive processes initiated by an eclipse are often enhanced by dynamic forces associated with large scale geophysical conditions not directly impacted by the solar eclipse. Our TEC estimation shows that the total ionization reduces up to 60% (after bias correction 40%) as a function of obscuration. Since the 20 March 2015 eclipse occurred during the negative phase of a severe geomagnetic storm on 17 March 2015, the observed TEC depletion is higher than those reported earlier for 1999 and 2005 eclipses. Thus, a negative bias of up to 20% was observed over Northern Europe already before the eclipse occurred. Moreover, the eclipse path of the solar eclipse in 2015 is traced at higher latitudes compared with eclipses observed in the years 1999 and 2005. The ionospheric response to the obscuration function is delayed up to 40 minutes decreasing with growing distance from the totality zone and increasing with altitude. The increasing delay with altitude is in agreement with earlier findings for other eclipses. The equivalent slab thickness was found to increase by approximately 80 -100 km during the solar eclipse on 20 March 2015 showing evidence for a pronounced loss in the bottomside ionosphere causing a delayed depletion of the topside ionosphere.

Public education in developing countries on the occasions of eclipses

NASA Astrophysics Data System (ADS)

Pasachoff, Jay M.

Total solar eclipses will cross southern Africa on June 21, 2001, and on December 4, 2002. Most of Africa will see partial phases. The total phase of the 2001 eclipse will be visible from parts of Angola, Zambia, Zimbabwe, Mozambique and Madagascar. The total phase of the 2002 eclipse will be visible from parts of Angola, Botswana, Zimbabwe, South Africa and Mozambique. Public education must be undertaken to tell the people how to look at the eclipse safely. We can take advantage of having the attention of the people and of news media to teach about not only eclipses but also the rest of astronomy. I am Chair of a "Public Education at Eclipses" subcommission of IAU Commission 46 on the Teaching of Astronomy, and we are able to advise educators and others about materials, procedures and information releases.

Solar Eclipse Effect on Shelter Air Temperature

NASA Technical Reports Server (NTRS)

Segal, M.; Turner, R. W.; Prusa, J.; Bitzer, R. J.; Finley, S. V.

1996-01-01

Decreases in shelter temperature during eclipse events were quantified on the basis of observations, numerical model simulations, and complementary conceptual evaluations. Observations for the annular eclipse on 10 May 1994 over the United States are presented, and these provide insights into the temporal and spatial changes in the shelter temperature. The observations indicated near-surface temperature drops of as much as 6 C. Numerical model simulations for this eclipse event, which provide a complementary evaluation of the spatial and temporal patterns of the temperature drops, predict similar decreases. Interrelationships between the temperature drop, degree of solar irradiance reduction, and timing of the peak eclipse are also evaluated for late spring, summer, and winter sun conditions. These simulations suggest that for total eclipses the drops in shelter temperature in midlatitudes can be as high as 7 C for a spring morning eclipse.

The effect of top-level domains and advertisements on health web-site credibility.

PubMed

Walther, Joseph B; Wang, Zuoming; Loh, Tracy

2004-09-03

Concerns over health information on the Internet have generated efforts to enhance credibility markers; yet how users actually assess the credibility of online health information is largely unknown. This study set out to (1) establish a parsimonious and valid questionnaire instrument to measure credibility of Internet health information by drawing on various previous measures of source, news, and other credibility scales; and (2) to identify the effects of Web-site domains and advertising on credibility perceptions. Respondents (N = 156) examined one of 12 Web-site mock-ups and completed credibility scales in a 3 x 2 x 2 between-subjects experimental design. Factor analysis and validity checks were used for item reduction, and analysis of variance was employed for hypothesis testing of Web-site features' effects. In an attempt to construct a credibility instrument, three dimensions of credibility (safety, trustworthiness, and dynamism) were retained, reflecting traditional credibility sub-themes, but composed of items from disparate sources. When testing the effect of the presence or absence of advertising on a Web site on credibility, we found that this depends on the site's domain, with a trend for advertisements having deleterious effects on the credibility of sites with .org domain, but positive effects on sites with .com or .edu domains. Health-information Web-site providers should select domains purposefully when they can, especially if they must accept on-site advertising. Credibility perceptions may not be invariant or stable, but rather are sensitive to topic and context. Future research may employ these findings in order to compare other forms of health-information delivery to optimal Web-site features.

Observing Solar Eclipses in the Developing World

NASA Astrophysics Data System (ADS)

Pasachoff, J. M.

2006-08-01

The paths of totality of total solar eclipses cross the world, with each spot receiving such a view about every 300 years. The areas of the world from which partial eclipses are visible are much wider. For the few days prior to a total eclipse, the attention of a given country is often drawn toward the eclipse, providing a teachable moment that we can use to bring astronomy to the public's attention. Also, it is important to describe how to observe the partial phases of the eclipse safely. Further, it is important to describe to those people in the zone of totality that it is not only safe but also interesting to view totality. Those who are misled by false warnings that overstate the hazards of viewing the eclipse, or that fail to distinguish between safe and unsafe times for naked-eye viewing, may well be skeptical when other health warnings--perhaps about AIDS or malaria prevention or polio inoculations--come from the authorities, meaning that the penalties for misunderstanding the astronomical event can be severe. Through the International Astronomical Union's Working Group on Solar Eclipses and through the I.A.U.'s Program Group on Public Education at the Times of Eclipses, part of the Commission on Education and Development, we make available information to national authorities, to colleagues in the relevant countries, and to others, through our Websites at http://www.eclipses.info and http://www.totalsolareclipse.net and through personal communication. Among our successes at the 29 March 2006 total solar eclipse was the distribution through a colleague in Nigeria of 400,000 eye-protection filters.

An effective patient quality assurance (QA) program for intensity-modulated radiation therapy (IMRT) requires accurate and realistic plan acceptance criteria--that is, action limits. Based on dose measurements performed with a commercially available two-dimensional (2D) diode array, we analyzed 747 fluence maps resulting from a routine patient QA program for IMRT plans. The fluence maps were calculated by three different commercially available (ADAC, CMS, Eclipse) treatment planning systems (TPSs) and were delivered using 6-MV X-ray beams produced by linear accelerators. To establish reasonably achievable and clinically acceptable limits for the dose deviations, the agreement between the measured and calculated fluence maps was evaluated in terms of percent dose error (PDE) for a few points and percent of passing points (PPP) for the isodose distribution. The analysis was conducted for each TPS used in the study (365 ADAC, 162 CMS,220 Eclipse), for multiple treatment sites (prostate, pelvis, head and neck, spine, rectum, anus, lung, brain), at the normalization point for 3% percentage difference (%Diff) and 3-mm distance to agreement (DTA) criteria. We investigated the treatment-site dependency of PPP and PDE. The results show that, at 3% and 3-mm criteria, a 95% PPP and 3% PDE can be achieved for prostate treatments and a 90% PPP and 5% PDE are attainable for any treatment site.

Consumer trust to a Web site: moderating effect of attitudes toward online shopping.

PubMed

San Martín, Sonia; Camarero, Carmen

2008-10-01

In this paper, authors suggest a model that reflects the role played by the Web site characteristics and the previous level of satisfaction as determinant factors of trust in the Web site. Also, authors consider the moderating effects of consumers' motives and inhibitors to purchase online. Results show that satisfaction with previous purchases, the Web site security and privacy policies, and service quality are the main determinants of trust. Also, the motives and inhibitors the individuals perceive when buying online determine the type of signals they consider to trust.

Okamura, Kyoko; Bernstein, Judith; Fidler, Anne T

2002-01-01

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.

Quality assurance of nursing web sites: development and implications of the ALEU method.

2011-09-01

This article presents a study that evaluated the physical accessibility, readability, and usability of Spanish nursing Web sites and discusses the quality assurance issues raised, which are relevant to the wider nursing community. The Internet is recognized as an important source of health information for both nurses and the general public. Although it makes health-related information universally available, the wide variation in the overall quality of health Web sites is problematic. This raises many questions for the nursing profession: about what constitutes a good-quality Web site, about the nature of the information that nurses are finding and using to support their professional education, research, and clinical practice, and about the impact that Internet information ultimately has on health interactions and nursing care. The process of completing this small study showed that it is possible to usefully assess dimensions of Web site quality and suggested that it may be feasible to develop tools to help nurses evaluate national and international nursing Web sites. More research is needed to understand how nurses use the Internet to support their everyday professional practices, but the development and application of international Web site quality assurance tools may be important for maintaining professional nursing standards in the Internet age.

An analysis of benefits and risk information on pharmaceutical web sites for the treatment of menopause.

PubMed

Charbonneau, Deborah H

2013-09-01

As the Internet is a source of information for many health consumers, there is a need to evaluate the information about prescription drugs provided on pharmaceutical manufacturers' web sites. Using a sample of pharmaceutical manufacturers' web sites for the treatment of menopause, the main objective of this study was to evaluate consumer-oriented information about benefits and risks of prescription drugs for the treatment of menopause provided on pharmaceutical web sites. Pharmaceutical manufacturers' web sites for analysis were identified using a list of U.S. FDA-approved hormone therapies for the treatment of menopause. This study revealed substantial gaps in how benefits and risk information were presented on the web sites. Specifically, information about the benefits was prominent while risk information was incomplete and challenging to find. Further, references to the scientific literature to support claims advertised about prescription drug benefits were not provided. Given the lack of scientific evidence to support claims of benefits and limited disclosure about risks, more information is needed for consumers to be able to weigh the benefits and risks of these treatments for menopause. Overall, these findings provide guidance for evaluating drug information provided on pharmaceutical web sites. © 2013 The author.

Schweitzer, Justin; Hannan, Alexander; Coren, Joshua

2012-10-01

Social networking Web sites such as Facebook have grown rapidly in popularity. It is unknown how such sites affect the ways in which medical trainees investigate and interact with graduate medical education (GME) programs. To evaluate the use of social networking Web sites as a means for osteopathic medical students, interns, residents, and fellows to interact with GME programs and report the degree to which that interaction impacts a medical trainee's choice of GME program. An anonymous, 10-item electronic survey on social networking Web sites was e-mailed to osteopathic medical student, intern, resident, and fellow members of the American College of Osteopathic Family Physicians. The weighted least squares test and the Fisher exact test were used for data analysis. A total of 9606 surveys were distributed, and 992 (10%) were completed. Nine hundred twenty-eight (93%) of the respondents used social networking Web sites, with the most popular services being Facebook (891 [90%]; P=.03), the Student Doctor Network (278 [28%]), and LinkedIn (89 [9%]; P=.03). Three hundred fifty-three respondents (36%; P=.52) were connected with a professional organization and 673 (68%; P=.73) used social networking Web sites for job searching related to GME programs or postresidency employment. Within the population of 497 third-, fourth-, and fifth-year osteopathic medical students, 136 (27%) reported gleaning information about programs through social networking Web sites (P=.01). Within the total population, 100 of 992 (10%) reported that this information influenced their decisions (P=.07). Of note, 144 (14%) of the total 992 respondents reported that the programs they applied to did not have any presence on social networking Web sites (P=.05). Our results indicate that social networking Web sites have a present and growing influence on how osteopathic medical students, interns, residents, and fellows learn about and select a GME program.

A Grid job monitoring system

NASA Astrophysics Data System (ADS)

Dumitrescu, Catalin; Nowack, Andreas; Padhi, Sanjay; Sarkar, Subir

2010-04-01

This paper presents a web-based Job Monitoring framework for individual Grid sites that allows users to follow in detail their jobs in quasi-real time. The framework consists of several independent components : (a) a set of sensors that run on the site CE and worker nodes and update a database, (b) a simple yet extensible web services framework and (c) an Ajax powered web interface having a look-and-feel and control similar to a desktop application. The monitoring framework supports LSF, Condor and PBS-like batch systems. This is one of the first monitoring systems where an X.509 authenticated web interface can be seamlessly accessed by both end-users and site administrators. While a site administrator has access to all the possible information, a user can only view the jobs for the Virtual Organizations (VO) he/she is a part of. The monitoring framework design supports several possible deployment scenarios. For a site running a supported batch system, the system may be deployed as a whole, or existing site sensors can be adapted and reused with the web services components. A site may even prefer to build the web server independently and choose to use only the Ajax powered web interface. Finally, the system is being used to monitor a glideinWMS instance. This broadens the scope significantly, allowing it to monitor jobs over multiple sites.

Tool independence for the Web Accessibility Quantitative Metric.

PubMed

Vigo, Markel; Brajnik, Giorgio; Arrue, Myriam; Abascal, Julio

2009-07-01

The Web Accessibility Quantitative Metric (WAQM) aims at accurately measuring the accessibility of web pages. One of the main features of WAQM among others is that it is evaluation tool independent for ranking and accessibility monitoring scenarios. This article proposes a method to attain evaluation tool independence for all foreseeable scenarios. After demonstrating that homepages have a more similar error profile than any other web page in a given web site, 15 homepages were measured with 10,000 different values of WAQM parameters using EvalAccess and LIFT, two automatic evaluation tools for accessibility. A similar procedure was followed with random pages and with several test files obtaining several tuples that minimise the difference between both tools. One thousand four hundred forty-nine web pages from 15 web sites were measured with these tuples and those values that minimised the difference between the tools were selected. Once the WAQM was tuned, the accessibility of 15 web sites was measured with two metrics for web sites, concluding that even if similar values can be produced, obtaining the same scores is undesirable since evaluation tools behave in a different way.
